[0067] The present utility model provides a linkage type test fixture and a test device, which are applicable to the application scenario of electrical testing of smart watches, and can effectively solve the problem that the FPC circuit is easily torn off.

[0068] See Figure 1 , the test device provided in this embodiment includes a workbench 100, a linkage type test fixture 200 detachably installed on the workbench 100, and a lateral pressing mechanism 300 located on the workbench 100 and used for laterally pressing the FPC fixture 3.

[0071] For the linkage test fixture 200 provided in this embodiment, when testing a smart watch, first switch the linkage mechanism 4 to the unlocked state, then rotate the rotating plate 2 in the forward direction (for example, rotate the rotating plate 2 to the horizontal state), and place the watch body of the smart watch on the fixed base plate 1; then rotate the rotating plate 2 in the reverse direction (for example, rotate the rotating plate 2 to the vertical state) so that the FPC fixture 3 approaches the watch body; then, place the FPC circuit of the smart watch into the FPC fixture 3; finally, switch the linkage mechanism 4 to the locked state, which on the one hand cooperates with the FPC fixture 3 to clamp the FPC circuit, and on the other hand restricts the relative rotation of the fixed base plate 1 and the rotating plate 2 to prevent the tester from accidentally rotating the rotating plate 2 and causing the FPC circuit to be torn off.

[0072] After the test is completed, first switch the linkage mechanism 4 to the unlocked state, and then the FPC circuit can be taken out of the FPC fixture 3, and the watch body can be taken out of the fixed base plate 1.

[0073] Therefore, the linkage test fixture 200 and the test equipment provided in this embodiment can effectively solve the problem that the FPC circuit is easily torn off.

[0074] Optionally, the fixed base plate 1 is provided with a workpiece placing groove 101 that opens upward and is used for placing the watch body. In this embodiment, the watch body is directly placed in the workpiece placing groove 101 without any pressing operation, so as to avoid tearing the FPC circuit caused by pressing the watch body downward.

[0075] The linkage mechanism 4 includes an FPC pressing plate 401, a push block 402, a connecting rod 403, and a limiting insertion rod 404. The FPC pressing plate 401 is slidably connected to the FPC fixture 3; the push block 402 is slidably connected to the rotating plate 2; one end of the connecting rod 403 is fixedly connected to the FPC pressing plate 401, and the other end is fixedly connected to the push block 402; one end of the limiting insertion rod 404 is fixedly connected to the push block 402, and the other end is used for clamping with the fixed base plate 1.

[0076] The fixed base plate 1 is provided with two vertical baffles 102, and an insertion rod space 103 for the other end of the limiting insertion rod 404 to be inserted is provided between the two vertical baffles 102; wherein, when the linkage mechanism 4 is in the locked state, the limiting insertion rod 404 is inserted into the insertion rod space 103; when the linkage mechanism 4 is in the unlocked state, the limiting insertion rod 404 is disengaged from the insertion rod space 103.

[0077] An active magnet 5 is fixedly provided on the push block 402, and a proximal magnet 6a and a distal magnet 6b are fixedly provided on the rotating plate 2. When the linkage mechanism 4 is in the locked state, the active magnet 5 is magnetically positioned with the proximal magnet 6a. When the linkage mechanism 4 is in the unlocked state, the active magnet 5 is magnetically positioned with the distal magnet 6b.

[0078] The FPC fixture 3 includes a fixture base 301 and a fixture cover plate 302. The fixture base 301 is provided with a test slot 3011 for placing the FPC circuit. A test probe for electrically connecting with the FPC circuit is provided at the bottom of the test slot 3011. Wherein, the FPC pressing plate 401 is slidably connected to the fixture base 301.

[0079] When the linkage mechanism 4 is in the locked state, the end of the FPC pressing plate 401 is inserted into the test slot 3011 and cooperates with the test probe to press the FPC circuit. When the linkage mechanism 4 is in the unlocked state, the end of the FPC pressing plate 401 exits the test slot 3011. The fixture cover plate 302 is hinged to the fixture base 301 and is used to cover the test slot 3011 to prevent dust and the like from entering the test slot 3011 and interfering with the test results.

[0080] See Figure 5 , the linkage type test fixture 200 further includes a test circuit board 11. The test circuit board 11 is fixedly provided at the bottom of the fixed base plate 1 and is electrically connected to the test probe through a connecting FPC for electrically testing the smart watch.

[0081] See Figure 6 , the lateral pressing mechanism 300 includes a lifting plate 7, a vertical linear driving mechanism 8, a lateral pressing block 9, and a horizontal linear driving mechanism 10. The driving end of the vertical linear driving mechanism 8 is connected to the lifting plate 7 to drive the lifting plate 7 to move up and down. The lateral pressing block 9 is disposed opposite to the FPC fixture 3. The driving end of the horizontal linear driving mechanism 10 is connected to the lateral pressing block 9 to drive the lateral pressing block 9 to press the FPC fixture 3.

[0082] For the test equipment provided in this embodiment, the detailed test process is as follows:

[0083] S10: Take out the linkage type test fixture 200 from the workbench 100, push the push block 402 so that the active magnet 5 is magnetically positioned with the distal magnet 6b. At this time, the linkage mechanism 4 is in the unlocked state, and the limit insertion rod 404 disengages from the insertion rod space 103. Therefore, the rotating plate 2 can be rotated to an inclined or horizontal state to avoid the FPC fixture 3 blocking the placing slot 101. Then, the watch body can be placed into the placing slot 101.

[0084] S20: Rotate the rotating plate 2 to the vertical state so that the FPC fixture 3 approaches the component placement groove 101;

[0085] S30: Open the fixture cover plate 302 and place the end of the FPC circuit into the test slot 3011;

[0086] S40: Push the push block 402 to magnetically attract and position the movable magnet 5 and the proximal magnet 6a. At this time, the linkage mechanism 4 is in the locked state:

[0087] On the one hand, the end of the FPC pressing plate 401 extends into the test slot 3011 and presses the end of the FPC circuit against the test probe, thereby realizing the electrical connection between the FPC circuit and the test circuit board 11;

[0088] On the other hand, the limit insertion rod 404 is inserted into the insertion rod space 103, and the vertical baffle 102 restricts the rotation of the limit insertion rod 404, thereby restricting the rotation of the rotating plate 2 to prevent the FPC circuit from being torn off accidentally by rotating the rotating plate 2;

[0089] S50: Place the linkage test fixture 200 on the workbench 100, and the vertical linear drive mechanism 8 drives the lifting plate 7 to move downward until the lateral pressing block 9 aligns with the fixture cover plate 302;

[0090] S60: The horizontal linear drive mechanism 10 drives the lateral pressing block 9 to laterally press the fixture cover plate 302. After that, the electrical test can be performed through the test main board.

[0091] The linkage test fixture 200 and the test equipment provided in this embodiment have the following advantages:

[0092] ① After placing the FPC circuit of the smart watch into the FPC fixture 3, switch the linkage mechanism 4 to the locked state. On the one hand, cooperate with the FPC fixture 3 to clamp the FPC circuit, and on the other hand, restrict the relative rotation of the fixed bottom plate 1 and the rotating plate 2 to prevent the test personnel from accidentally rotating the rotating plate 2 and causing the FPC circuit to be torn off;

[0093] ② Set the proximal magnet 6a and the distal magnet 6b for magnetic attraction positioning in the locked state and the unlocked state to improve the feel of locking and unlocking.

[0094] It should be noted that the linear drive mechanism mentioned in the present invention can be a cylinder, a hydraulic cylinder, an electric cylinder, or a motor screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, a brushless motor, or a rotary cylinder, etc. The present invention does not limit the specific structural forms of the linear drive mechanism and the rotary drive mechanism.
