With the development of science and technology and society, people have gradually entered into today's technological society from the original primitive society. The emergence of various electronic devices has made people's lives more and more convenient. Electronic devices are the result of industrialization. The backwardness of electronic equipment leads to the large size of electronic equipment, which is inconvenient to use. However, with the emergence of integrated technology, the problem of large size of electronic equipment has been solved. Through integrated technology, various electronic components are concentrated on circuit boards, thereby The volume of electronic equipment is greatly reduced, and PCB is the key to integrated technology. The full name of PCB is printed circuit board. Its main function is to connect various electronic components in the equipment. It is a vital component of electronic products. PCBs can be divided into three types: single-sided, double-sided and multi-layered boards according to the number of circuit layers, and the multi-layered boards are made by pressing multiple single-sided and double-sided boards. During the bonding process, a pressing device is often used.

After searching, the existing patent publication number CN112235944A discloses a pressing device for PCB production. The pressing device for PCB production includes: a bottom plate; four supporting legs, each of which is It is fixedly installed at the bottom of the bottom plate, and the four supporting legs are distributed in a rectangular array; two upright plates, both of which are fixedly installed on the top of the bottom plate; horizontal plate, the horizontal plate is fixed Installed on the top of the two vertical plates; two U-shaped rods, the two U-shaped rods are respectively fixed and installed on the sides of the two vertical plates close to each other; two sliding blocks, two The sliding blocks are respectively slidably installed on the corresponding U-shaped rods; the lower pressing plate is arranged above the bottom plate, and the sides of the two sliding blocks that are close to each other are fixedly connected with the lower pressing plate .

But it still has the following disadvantages in actual use:

1. The pressing device used for PCB production in the document usually uses rollers to roll on the surface of the board before pressing the PCB. The rolling of the rollers makes the connection between the layers more tightly, but When the roller is rolling, friction is generated between the roller and the plate. Under the action of the friction force, the plate moves in the opposite direction to the movement of the roller, which causes the position of the upper plate to change, thus affecting the pressing effect, so it is inconvenient. use;

2. For the pressing device used for PCB production that appears in the document, after the PCB pressing is completed, the staff needs to manually remove the pressed plate, which increases the workload of the staff, and the staff manually takes the material When the equipment is closed, the equipment needs to be turned off, which results in the need to repeatedly turn off and on the equipment when the plate is continuously pressed. Frequent switching of the equipment will affect the service life of the equipment, so it is not convenient to use;

3. The pressing device used for PCB production appeared in the document. During the pressing process, due to the thin thickness of the plate, if the pressure is too large during the pressing process, the plate will be broken. The document used for PCB The produced pressing device did not take measures against the excessive pressure of the equipment, so that during the pressing process, if the first motor fails during the working process, the pressure of the lower pressing plate will be too high, which will cause the plate to break, thereby reducing the cost of the machine. Yield, so inconvenient to use.
