[0033] When the first position adjustment component is working: the output shaft of motor 2 502 drives screw 1 503 to rotate, and when screw 1 503 rotates, it drives the spline shaft 304 to slide in the spline sleeve 303 through the position adjustment plate 501, and the spline shaft 304 drives the slider 707 to move through the second position adjustment component, and the slider 707 drives the detection mechanism to move in the vertical direction, thereby adjusting the position of the detection mechanism in the vertical direction.

[0034] When the second position adjustment component is working: the output shaft of the motor three 602 drives the screw two 603 to rotate, and the screw two 603 drives the slider 707 to move when rotating, and the slider 707 drives the detection mechanism to move in the horizontal direction, thereby adjusting the position of the detection mechanism in the horizontal direction.

[0035] When the slider 707 and the detection mechanism are working: when the flexible circuit board needs to be tested, pull the detection frame 701, the detection frame 701 drives the support plate five 705 to slide on the slider 707, and then drives the support plate four 702, the detection rod 703 and the detection head 704 to move, and place one end of the flexible circuit board to be tested between the two detection heads 704, release the detection frame 701, and under the action of the spring one 706 and the spring two 708, multiple detection heads 704 arranged face to face clamp one end of the flexible circuit board (the number of detection heads 704 is set according to the actual flexible circuit board to be tested), and the two ends of the flexible circuit board are clamped respectively by two detection mechanisms; at the same time, the test pins on the flexible circuit board are connected to the corresponding detection heads 704, and the circuit changes are monitored in real time through an external circuit detection device.

[0036] When the reciprocating swing assembly and the driving assembly are working: the output shaft of the motor 1 202 drives the rotating rod 208 to swing, the rotating rod 208 drives the slide bar 207 to slide back and forth in the vertical direction on the guide rod 1 206, and the slide bar 207 slides back and forth in the rotating rod 208, the slide bar 207 drives the rotating rod 1 205 to rotate back and forth through the guide rod 1 206, the rotating rod 1 205 drives the rotating shaft 204 to rotate back and forth, the rotating shaft 204 drives the pulley 2 305 to rotate back and forth, and the pulley 2 305 The belt 301 drives the pulley 1 302 to reciprocate, the pulley 1 302 drives the spline shaft 304 to reciprocate through the spline sleeve 303, the spline shaft 304 drives the slider 707 to reciprocate through the second position adjustment assembly, the slider 707 drives one end of the connected flexible circuit board to reciprocate through the detection mechanism, and the swing angle of the rotating rod 1 205 is changed by replacing the rotating rod 208 of different sizes, thereby changing the reciprocating rotation angle of one end of the flexible circuit board.

[0037] The working principle of the present invention is:

[0038] The two ends of the flexible circuit board to be tested are clamped respectively by two detection mechanisms, and at the same time, the corresponding detection head 704 is connected to the test pin on the flexible circuit board. One of the reciprocating swing components drives a connected driving component to work, and the driving component drives the detection component to rotate through the second position adjustment component. The detection component drives one end of the flexible circuit board to rotate, and the other reciprocating swing component and the connected driving component remain stationary, so that the other end of the flexible circuit board is fixed, so that the flexible circuit board is reciprocated and twisted. During the reciprocating twisting process, the circuit changes (including resistance changes, short circuit, etc.) are monitored in real time through an external circuit detection device, so as to realize automatic torsion test of the flexible circuit board and detect whether the flexible circuit board is faulty in real time.

[0039] When it is necessary to perform a torsion test on the same flexible circuit board at different placement angles: the position of the flexible circuit board is adjusted through the cooperation of the first position adjustment component and the second position adjustment component, so that the flexible circuit board can be twisted at different inclination angles, and an external circuit detection device is used to detect in real time whether the circuit fails when the flexible circuit board is twisted in different postures, thereby simulating the situation when the user wears the smart wearable device in reality to the greatest extent, so as to ensure the reliability and durability of the smart wearable device when in use, and solving the problem that the prior art can only perform torsion tests on the flexible circuit board in the same posture, resulting in the test results not being able to fit the actual situation to the greatest extent.

[0040] When different flexible circuit boards need to be tested: through the cooperation between the first position adjustment component and the second position adjustment component, the positions of the two detection components are adjusted to adapt to the detection of different flexible circuit boards (the working principle of the detection refers to the previous one).

[0041] When the test on one end of the flexible circuit board is completed, the tested end remains fixed, and the previously fixed end is rotated, so that different ends of the flexible circuit board can be twisted, which solves the problem in the prior art that usually only one end of the flexible circuit board can be twisted, resulting in incomplete test results.

[0042] By replacing the rotating rod 208 of different sizes to change the swing angle of the rotating rod 1 205, the reciprocating rotation angle of one end of the flexible circuit board is changed to achieve testing of different torsion angles of the flexible circuit board, thereby improving the applicable scope of flexible circuit board testing.

[0043] It should be particularly noted that the start and stop of the above-mentioned power parts, the real-time feedback of the detection results and the overall working process of the present invention are all controlled by the software control unit and the hardware control unit.

the spline shaft (304) and the position adjustment plate (501) are rotatably connected; and the spline shaft (304) and the position adjustment plate (501) are relatively fixed in a vertical direction; the pulley 1 (302) is fixedly mounted on the spline sleeve (303); the pulley 1 (302) and the pulley 2 (305) are connected via a belt (301); and the position adjustment frame (601) is fixedly mounted on an end of the spline shaft (304) away from the spline sleeve (303).
