[0002] In the prior art, circuit board inspection machines are widely used in the field of circuit board inspection. However, there are two types of press plates used in circuit board industry inspection machines: one is a manual press plate, which is based on a rotating shaft, and the press plate is opened and closed by hand. This is only suitable for small circuit boards, which are larger than 500 mm, or when measuring many times a day, the operator has to open and close the press plate constantly, and the labor intensity is high. Since part of the press plate is glass, it is also prone to danger; the other electric press plate is based on the principle of adding two electric push rods to the manual press plate, so that the press plate can be raised and lowered according to the up and down buttons. In this way, a large press plate can be lifted, but the finger must keep pressing the button to rise and fall. Remember to put the press plate down before the machine moves, otherwise there will be a collision. In addition, when there is a power outage, the electric push rod will drop by itself, which is unsafe for the operator, with a low degree of automation, poor coordination, unsmooth operation, and poor practicality.
