The two groups of threaded blocks 405 are both slidably connected to the slide groove 402. It should be noted that in order to ensure that the two groups of threaded blocks 405 move in opposite directions, the threaded rod 404 is divided into two sections of threads with opposite rotation directions.

[0028] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0030] During appearance inspection, the electric slider 3 drives the appearance inspection mechanism 5 to move to the top of the flip mechanism 6. At this time, the appearance inspection camera 502 will obtain the appearance information of the double-sided flexible circuit board and transmit the information to the PLC controller 503, thereby judging whether the product is qualified. During conductivity inspection, the electric slider 3 drives the conductivity test mechanism 4 to move to the top of the flip mechanism 6, and the electric telescopic rod 406 extends to push the measuring pen 407 to perform conductivity inspection on the circuits at both ends of the double-sided flexible circuit board, and transmit the inspection information to the multimeter 408. The multimeter 408 realizes the display of data, and the flip mechanism 6 can realize the rotation of the double-sided flexible circuit board, so as to perform appearance inspection and conductivity inspection on the other side of the double-sided flexible circuit board.

[0031] When the length of the double-sided flexible circuit board changes, it is necessary to replace the first optical glass plate 603 and the fixing mechanism 7 that are compatible with it for fixing, and at the same time drive the first servo motor 403, the first servo motor 403 drives the threaded rod 404 to rotate, the threaded rod 404 drives the two groups of threaded blocks 405 to move, and then drives the electric telescopic rod 406 and the measuring pen 407 to move, so as to adjust the distance between the two measuring pens 407 to ensure that the distance can adapt to the length of the double-sided flexible circuit board, thereby ensuring the accuracy of the measurement result.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
