There are also applications of industrial robots in the PCB industry

with the improvement of robot performance and the decline of price, the production mode of replacing the traditional automatic equipment + manual operation with automatic equipment + industrial robot operation will become the trend of the transformation and development of the fuel cell industry published by PC Galaxy Securities

pcb industry is a technology intensive and capital intensive industry, but it is still a labor-intensive industry. A large number of automation equipment requires manual operation and assembly line operation. A medium-sized PCB enterprise has thousands of employees. With the industrial transfer and upgrading, the implementation of the new labor contract law, the rise in the cost of living in cities brought about by the transformation of economic structure, and the difficulty and mobility of the post-80s and post-90s staff, PCB manufacturers are facing more and more serious challenges of labor shortage and rising labor costs, as well as the consequent impact on production plans, product quality and profitability. At the same time, with the improvement of robot performance and the decline of price, replacing the traditional production mode of automatic equipment + manual operation with automatic equipment + industrial robot operation will become the trend of the transformation and development of PCB industry

I. types and characteristics of industrial robots

?? Industrial robot?? It is a kind of multi-functional and multi degree of freedom mechatronic automatic mechanical equipment and system that can complete some operational tasks in the manufacturing process through repeated programming and automatic control. Combined with the manufacturing host or production line, it can form a single machine or multi machine automatic system to realize various production operations such as handling, welding, sorting, assembly and spraying without participation

since the first generation of robots came out in the United States in the early 1960s, the development and application of industrial robots have developed rapidly and are increasingly widely used in production. They have become important highly automated equipment in modern manufacturing

industrial robot is mainly composed of body (including mechanical trunk part, motor and reducer) and electric control (including drive and control system). Its function is to use the actuator at the end to grasp objects or tools instead of hands and complete different tasks. At present, there are three kinds of mainstream industrial robots, including SCARA (four axis parallel joint robot), Delta (parallel robot) and six axis multi joint robot (including multi joint robot with more than six axes and derived double arm robot)

the most remarkable characteristics of industrial robots are summarized as follows:

1, programmable. The further development of production automation is flexible automation. Industrial robots can be reprogrammed according to their work tasks and the needs of environmental changes. Therefore, they can play a good role in the flexible manufacturing process of small batch, multi variety, balanced and efficient. They are an important part of flexible manufacturing system (FMS)

2. Personification. Industrial robots have human like walking, waist turning, big arms, small arms, wrists, claws and other parts in mechanical structure, and computers in control. In addition, intelligent industrial robots have many biosensors similar to human beings, such as skin contact sensors, force sensors, load sensors, visual sensors, sound sensors, language functions, etc. Sensors improve the adaptability of industrial robots to the surrounding environment

3. Universality. In addition to specially designed industrial robots, general industrial robots have good versatility when performing different tasks. For example, you can use the "experiment" button on the control board to replace the industrial robot hand end manipulator (claws, tools, etc.) to perform different tasks

II. Application cases of industrial robots in the PCB industry

industrial robots were mainly used in the automobile manufacturing industry in the early stage, and completed welding, assembly, handling, spraying and other work in the automobile production process. These links do not require high precision and speed of robots. However, the situation of PCB industry is relatively complex. The application of robots in PCB industry is mainly reflected in the functions of loading and unloading, turnover, sorting, positioning and detection of each process, which should replace manual cooperation with the operation of PCB board processing equipment and detection equipment. Due to the diversity and complexity of PCB boards, there are single-layer boards, double-layer boards, multi-layer boards, flexible boards, soft and hard combination boards, non perforated boards and perforated boards, which lead to more requirements for front-end actuators; There are also requirements for positioning accuracy and work rhythm, so the requirements for robot technology and integration technology are also high in the application of industrial robots. After nearly two years of exploration and practice in the industry, we have worked hard to help customers solve problems, meet customer needs, and have accumulated experience in industry application. At present, we have mature solutions for many processes in the PCB industry, such as AOI, exposure machine, target drilling machine (ope, XZ), silver slurry hole filling, text inkjet, browning pre stacking, finished product loading, OSP, finished product cleaning, dome film reverse coating, LCD assembly, etc

the following focuses on three representative application cases of robots when the pendulum is in the vertical downward rest position:

1. Six axis multi joint robots are used in the AOI detection process

traditional AOI scanning machines rely on manual plate placing, plate turning and plate receiving. One person takes care of two machines, doing repetitive monotonous actions every day, and the newly made circuit board will also emit a pungent smell, which will cause certain harm to the human body, The infrared light emitted by AOI scanning machine is also an invisible killer. We use a six axis multi joint robot to replace the workers to be responsible for the release, turnover and retraction of two AOI boards. Each shift can complete the retraction and retraction of more than 700 PCB hard boards, and the comprehensive efficiency can reach the coal production capacity reduction effect, which is rapidly increasing with ldquo; Start a prairie fire rdquo; The potential is transmitted to more downstream 1 block/min (including AOI machine scanning time). If we can further connect the loading and unloading transportation line matched with the retracting and releasing machine to the AGV for fixed line transportation, we can realize the fully automated production of the upper and lower processes

2. SCARA robot is used in the circuit board coil detection process

at present, there are few complete sets of detection equipment for multilayer board coil short circuit on the market. Most of the detection equipment depends on manual work. PCB boards with large aperture are manually placed on the detection equipment and then turned on for equipment detection, The PCB board with small aperture needs to manually hold the equipment (probe) to detect each coil. Using SCARA robot, we can complete the loading and unloading and positioning of the detection equipment, and realize the one-time detection of all the coils of the large aperture board; For plates with small aperture, we use SCARA equipment to fix the probe at the execution end, and use the probe to detect each coil through visual positioning. Our equipment also effectively avoids missing detection due to small or large aperture of the coil during manual operation. Compared with manual operation, it can significantly improve the detection efficiency and avoid quality problems caused by missed detection

3. Delta robot is used for the cartoning process of small circuit board finished products

the existing FPC cartons are manually picked up one by one and put into the blister tray. Because FPC is soft and thin, it is inconvenient to pick it up, so the efficiency will be greatly reduced. Delta800 plus a set of vision system can pick out qualified FPC from the messy FPC stack and place it in the blister tray as required, The effect is not inferior to manual work. Its speed can reach 60 pieces/min, which can completely replace manual sorting and tray loading

III. advantages of industrial robot replacing labor in PCB industry

as in automobile industry and other manufacturing industries, industrial robot replacing labor in PCB industry brings many advantages to enterprises

1. Reduce employment, speed up work pace and improve work efficiency. Robots can achieve high-speed repetitive operations, which can be much higher than the work rhythm of labor, thus bringing a substantial increase in work efficiency and a reduction in labor costs and management costs

2. Improve operation accuracy and product quality. The robot can use programming and vision system to achieve accurate positioning and repetition accuracy, which effectively improves the quality of products

3. Avoid the potential threat of the working environment to workers' health and safety, and save investment in environmental safety

4. Reduce the decline of efficiency and quality and accident rate caused by the impact of repeated and boring processes on workers' status

5. Optimize the working process and reduce the working space

6. Effectively reduce the material consumption rate

7. It can work continuously for 24 hours and in a black light environment

8. It can make the manufacturing process flexible. In the future, there will be more and more small batch orders in the PCB industry. The use of industrial robots can greatly improve the flexibility of production and realize the rapid delivery of orders

9. Improvement of brand image and reputation. The application of industrial robots has further improved the automation level of PCB manufacturers, driven the progress of product quality, production efficiency, cost control, response ability and so on, and improved the overall competitive strength of manufacturers in the industry

IV. application prospect of industrial robots in PCB industry

at present, the application of industrial robots in PCB industry is still in its infancy, and it still faces many problems that need to be solved. Many operation lines in the PCB industry are non-standard products. In the process of robot application, they will be limited by the existing working space and the capacity of the original equipment. In the face of the influence of different PCB board materials, we should also consider the application of various sensors to improve the intelligence of the robot, and also consider training a group of employees who can operate and maintain the robot for manufacturers

in the future, the application of industrial robots in PCB industry will show the following trends:

1, from single station or single line application to multi line application. It is difficult for existing PCB enterprises to fully introduce robots to realize automatic production, which requires a lot of money to transform, but they can carry out step-by-step transformation on qualified single station and single line, and gradually expand the scope of application after achieving obvious results

2. From the application of simple robots to the application combined with AGV and other intelligent equipment. Most of the material transfer between the existing process production lines are manual operations, which can be implemented in a distributed manner, and the orderly transfer of materials can be realized by the combination of robots and AGVs

3. The existing factories are mainly for local applications, and the construction of the new factory will be planned as a whole, directly introducing the application of robots and AGV

4. The combination of industrial robots and IOT will make the manufacturing process more intelligent and flexible
