[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards; circuit board pressing equipment is one of the important equipment used in the production of circuit boards in the electronics manufacturing industry. Its basic principle is to press multi-layer circuit board sheets into ordinary and simple composite boards by heating and pressurizing.

[0003] In the prior art, when the automated pressing device for processing circuit boards is working, the circuit board to be pressed needs to be placed in the center manually or with the assistance of an external robotic arm. If the placement deviates, it is easy to cause the hidden danger of the circuit board not being pressed in place, reducing the accuracy of circuit board feeding. After the circuit board is pressed, the surface of the circuit board is easily adsorbed to the plane of the equipment due to air pressure, making it difficult to stably feed the pressed circuit board.

[0004] Therefore, it is necessary to invent an automated pressing device for circuit board processing to solve the above problems, which can increase the convenience of loading and unloading circuit boards in the circuit board pressing equipment. Summary of the invention
