[0030] Please refer to Figure 1 and Figure 2 , Figure 1 is a perspective structural schematic view of a circuit board pressure testing machine 100 according to an embodiment of the present application; Figure 2 is Figure 1 a cross-sectional structural schematic view of the circuit board pressure testing machine 100. The present application provides a circuit board pressure testing machine 100, which comprises a rack 10, a mounting plate 20, a display assembly 30 and a pressure testing assembly 40. The rack 10 is used to carry the circuit board to be tested, the mounting plate 20 is connected with the rack 10, the display assembly 30 is connected with the rack 10 and is opposite to the mounting plate 20 at intervals. The pressure testing assembly 40 comprises a pressure plate 41, a protective plate 42 and a driving member (not shown), the pressure plate 41 is slidingly connected with the mounting plate 20 and is located at the bottom side of the mounting plate 20, and the protective plate 42 is connected with the pressure plate 41. When the driving member drives the pressure plate 41 to slide relative to the mounting plate 20 so that the pressure plate 41 abuts against the circuit board to be tested, the protective plate 42 is located between the mounting plate 20 and the display assembly 30.

[0031] Specifically, the rack 10 comprises a bearing surface 101, the bearing surface 101 is used to place the circuit board to be tested, the bearing surface 101 is opposite to the mounting plate 20, and the pressure plate 41 is located between the bearing surface 101 and the mounting plate 20. The rack 10 is also used to be arranged on a support surface such as the ground or the surface of other equipment. The pressure plate 41 is provided with an electrical testing member, the electrical testing member is used to be connected with the circuit board to be tested when the pressure plate 41 abuts against the circuit board to be tested, and sends a test signal to the circuit board to be tested to test the circuit board to be tested. The electrical testing member can be selected as a contact pin. The driving member can be selected as a component such as an electric cylinder, an air cylinder or a hydraulic cylinder, and the type of the driving member is not limited in the present application.

[0032] It can be understood that during the testing process, the driving member drives the pressing plate 41 to slide relative to the mounting plate 20 towards the bearing surface 101, so that the pressing plate 41 is pressed against the circuit board to be tested, and at this time, the pressing plate 41 is at the lowest position. After the testing is completed, the driving member drives the pressing plate 41 to slide relative to the mounting plate 20 away from the bearing surface 101, so that the pressing plate 41 is lifted away from the circuit board to be tested, the pressing plate 41 is separated from the circuit board to be tested, and the pressing plate 41 returns. During the testing process and after the testing is completed, the protection plate 42 moves with the pressing plate 41, and when the pressing plate 41 is in contact with the circuit board to be tested, that is, when the pressing plate 41 is at the lowest position, the protection plate 42 is located between the mounting plate 20 and the display assembly 30, so that the protection plate 42 can always block the user from putting his hand between the pressing plate 41 and the mounting plate 20 during the testing process and after the testing is completed.
