BACKGROUND

[0002] Today's manufacturing industry is facing labor shortage and rising environmental awareness, labor and operating cost, and the pressure of transforming from labor-intensive to technology-intensive. Most manufacturers respond to rising costs by moving their industry or introducing foreign labor. Production line automation technology and jigs can also be used to improve business conditions and reduce costs to achieve the goal of reducing manpower, saving manufacturing time and improving productivity.

[0003] Furthermore, in the production line automation operation of the manufacturing industry, different workstations in the factory building are usually used for various processing, inspection, cleaning, assembly, quality control, storage and transportation production processes. In the processing production process, the trolley of the conveying device and the conveying belt are used to convey the workpiece to be processed to each workstation position, and the workpiece is taken or replaced by manual operation. The processing tool is used to process various required components and products. This manual operation for taking or replacing is quite time-consuming and labor-intensive, so manufacturers introduce industrial lines with robotic arms for handling to meet the needs of automation and special processes.

[0004] In the process of traditional automated manufacturing of circuit boards, to avoid scratches and wear on the surface of the circuit board, multiple circuit boards must be arranged horizontally to be transported by a conveyor belt to a robotic arm for handling and processing operations. Therefore, the production plant must use a larger space to accommodate production equipment, which increases costs. A better solution to save space is to vertically stack multiple circuit boards to be processed. Of course, some processing jigs are needed as a protective structure for the circuit board to achieve this, which is the subject of the utility model developed and improved.

TWM624706 and TWM626284, both of which are new type patents previously applied by the applicant, both of which disclose a circuit board bearing group, and the bearing group includes a plurality of carriers in a vertical stacked structure, and the carrier includes a tray and a plurality of foot pads (or a plurality of combination members).

In addition, the tray is an aluminum plate produced by an aluminum extrusion method, which has a higher production cost and increases the production cost of the circuit board, which is not conducive to the competitiveness of the market price. The above-mentioned shortcomings need to be solved by those engaged in this industry. Utility Model Content
