[0026] The circuit board to be tested is placed on the movable plate 17 and the annular frame 23, and then the electric telescopic rod 11 is started.

[0027] The outer portion of the sliding rod 15 is slidably inserted into the inner ring of the buffer spring 16 , and both ends of the buffer spring 16 are supported between the fixed plate 12 and the clamping plate 18 .

[0028] After the circuit board is clamped by the first clamping plate 18 and the second clamping plate 24, the fixed plate 12 moves toward the second clamping plate 24, so that the fixed plate 12 causes a certain compression to the buffer spring 16. The buffer spring 16 plays a certain protective role on the circuit board, preventing the fixed plate 12 from moving excessively and causing the first clamping plate 18 to damage the circuit board.

[0029] Rollers 14 are installed on both sides of the movable plate 17 , and the outer portions of the rollers 14 are rollingly connected to the inner walls of the two sets of U-shaped tracks 19 .

The bottom of Y-axis electric slide 31 is fixedly connected to the top of one side of annular frame 21, and the top of the other side of annular frame 21 is fixedly connected to the bottom of slide rail 34.

In this way, the cross laser marker 37 and the detection camera 35 can stop and perform detection at any location on the circuit board, ensuring the comprehensiveness and reliability of the test. The cross laser marker 37 marks the surface of the circuit board, and the detection camera 35 can take pictures of the marked area.

[0034] The working principle of the present invention is as follows: when in use, the circuit board to be tested is placed on the movable plate 17 and the annular frame second 23, and then the electric telescopic rod 11 is started, the electric telescopic rod 11 pushes the movable plate 17 to move in the direction of the clamping plate second 24, and the movable plate 17 drives the fixed plate 12 on its upper side to move in the direction of the clamping plate second 24, and the fixed plate 12 pushes the buffer spring 16 and the clamping plate 18 to move in the direction of the clamping plate second 24, so that the clamping plate 18 and the clamping plate 24 are clamped and fixed to the circuit board, avoiding the movement of the circuit board during the detection process, thereby ensuring the detection effect; by controlling the telescopic length of the electric telescopic rod 11, and then controlling the spacing between the clamping plate 18 and the clamping plate 24, the spacing between the clamping plate 18 and the clamping plate 24 can be adjusted according to the specific size of the circuit board, so that the clamping plate 18 and the clamping plate 24 can clamp and position circuit boards of different sizes, thereby improving the applicability of the test platform and making the test platform more convenient to use.
