PCB Circuit Board Application Robot Will Become A Trend

Jan 16, 2018

The PCB industry is a technology-intensive and capital-intensive industry, but it is still a labor-intensive industry. A large number of automation devices require manual operations and pipelining. A medium-sized PCB company has thousands of employees.

With the transfer and upgrading of industries, the implementation of the new labor contract law, the rise of urban living costs brought about by the economic structural transformation, and the difficulty of management after the 80,90 staff and large liquidity, PCB manufacturers are experiencing more and more serious The labor shortage and rising labor costs, and the consequent impact on production planning, product quality and profitability. At the same time, with the improvement of robot performance and the decrease of price, the production mode of "automation equipment + manual operation" replaced by "automation equipment + industrial robot operation" will become the trend of PCB industry transformation and development.


Robot representative applications:

1, six-axis multi-joint robot for AOI testing procedures

Traditional AOI scanning machines rely on manual release, flap and close the plate, a person custody of two machines, each doing repetitive monotonous movements, and just produced a good circuit board will emit a pungent odor on the human body Bring some damage, infrared light emitted by the AOI scanning machine is also an invisible killer. We use a six-axis multi-joint robot, instead of two AOI workers responsible for the board, flap and close the plate, each class can be completed more than 700 PCB hard board retractable, the overall efficiency can reach 1 / min ( Including AOI machine scan time). If we can further with the retractable plate machine with the loading and unloading transport lines, connected to the AGV fixed line transport, you can achieve the upper and lower process of fully automated production.


2, SCARA robot for circuit board coil inspection process

The current multilayer PCB short circuit detection equipment is still very small, most of the testing equipment are dependent on artificial, large aperture PCB board is manually put the board above the test equipment and then open the device testing, small aperture PCB board Need to manually hold the device (probe) to detect each coil. We use the SCARA robot to complete the loading and unloading of the inspection equipment and the alignment, to achieve a one-time inspection of all the coils in the board with a large aperture. For the small aperture board, we use the SCARA device to perform the end fixation and visual positioning , With the probe on each coil for testing, our equipment is also effective to avoid manual operation due to small coil diameter or pore size and missed inspection. Compared with the manual operation can significantly improve the detection efficiency, and to avoid quality problems caused by missed inspections.


3, DELTA robot for small circuit board assembly process

The existing FPC loading plates are manually picked up and placed in a plastic tray inside, due to the FPC soft and thin in the pick very inconvenient and therefore will greatly reduce the efficiency, Delta800 plus a visual system can be messy The FPC heap out qualified and then placed in the plastic tray as required, the effect is not inferior to the artificial. His speed can reach 60 / min, can completely replace the manual sorting tray.


Industrial robots in the PCB industry to replace the advantages of artificial

As with the automotive industry and other manufacturing industries, industrial robots bring many advantages to enterprises in the PCB industry instead of labor.


1, to reduce employment, speed up the work beat, improve work efficiency. Robots can achieve high-speed repetitive operations, which can be far higher than the manual beat, resulting in a substantial increase in work efficiency and labor costs, management costs.


2, improve job accuracy, improve product quality. Robots can use programming and vision systems to achieve accurate positioning and repeat accuracy, effectively improving product quality.


3, to avoid the potential threat to the health and safety of workers in the working environment, saving the environmental safety investment.


4, to reduce duplication, boring process on the worker status caused by the decline in efficiency and quality and the accident rate;


5, optimize the operation process, reducing the work space.


6, effectively reduce the material consumption rate.


7, 24 hours of continuous operation and work in black light environment;


8, can make the manufacturing process flexible. The future PCB industry will appear more and more small orders, the use of industrial robots can greatly enhance the production flexibility to achieve the rapid delivery of orders.


9, enhance the brand image and reputation. The application of industrial robot makes PCB manufacturers to further enhance the level of automation and promote product quality, production efficiency, cost control, responsiveness and other aspects of progress, improve the overall competitiveness of manufacturers in the industry.


Industrial robots in the PCB industry prospects

At present, the application of industrial robots in the PCB industry has just started, but also faces a lot of problems to be solved. Many industry lines in PCB industry are non-standard products, which are limited by the existing work space in the process of application of robots. Due to the limitation of the original equipment capacity and the influence of different PCB material factors, various sensors should be considered to improve the robot Intelligent, but also consider training a number of manufacturers for the operation and maintenance of the robot staff.


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

1, from a single station or single-line applications, to multi-line applications. Existing PCB enterprises want to fully introduce robots to achieve automated production more difficult, need to invest a lot of money to transform, but can be conditional on the single-station and single-step transformation, to be significantly effective, and then gradually expand the scope of application.


2, from the application of pure robot and other intelligent equipment such as AGV combination of applications. Most of the existing production line between the material transfer for manual operation, can be distributed to achieve the implementation of the robot and AGV in order to achieve the orderly transmission of materials.


3, the existing factory to local applications, the new plant construction will do the overall planning, direct introduction of robots and AGV applications.


4, through the combination of industrial robots and the Internet of Things, will make the manufacturing process more intelligent and flexible.


In summary, we can foresee: the future of the PCB industry will be a wide range of industrial robots.
