Referring to fig. 1 and 2, an embodiment of the present invention provides a detection tool for clamping a product a to detect the product a. The detection jig comprises a mounting bracket 10, a clamping assembly 20, a supporting assembly 30 and a linkage assembly 40.

The clamping assembly 20 includes a fixed clamping portion 21 and a movable clamping portion 22 disposed at intervals along the first direction X on the mounting bracket 10. A clamping position (not shown) for clamping the product a is formed between the fixed clamping portion 21 and the movable clamping portion 22, and the movable clamping portion 22 is configured to be operatively adjacent to or distant from the fixed clamping portion 21. The movable clamping part 22 can clamp the product A in the clamping position when moving close to the fixed clamping part 21; the product a in the gripping position can be released (i.e., the gripping of the product a is released) when the movable gripping portion 22 moves away from the fixed gripping portion 21. The support assembly 30 includes a first support 31 and a second support 32 provided on the mounting bracket 10. The first supporting member 31 and the second supporting member 32 are respectively located at two sides of the clamping position in the second direction Y, and the second direction Y intersects with the first direction X. Preferably, the second direction Y is perpendicular to the first direction X.

The movable clamping part 22 is in transmission connection with the first supporting piece 31 and the second supporting piece 32 through the linkage assembly 40. When the movable clamping part 22 moves away from the fixed clamping part 21, the first supporting piece 31 and the second supporting piece 32 are driven to move close to each other by the linkage assembly 40 so as to support the product A at the clamping position; when the movable clamping part 22 moves close to the fixed clamping part 21, the first supporting member 31 and the second supporting member 32 are driven to move away from each other by the linkage assembly 40, so as to release the support of the product A at the clamping position.

When the product a needs to be clamped, the detection tool controls the movable clamping portion 22 to move away from the fixed clamping portion 21, so that the first supporting member 31 and the second supporting member 32 are driven to approach each other by the linkage assembly 40 until the movable clamping portion extends into the clamping position. At this time, the product a can be placed in the clamping position, and the first supporting member 31 and the second supporting member 32 are used to support the product a, so as to prevent the product a from falling. Then, the movable clamp portion 22 is controlled to move close to the fixed clamp portion 21 so that the movable clamp portion 22 and the fixed clamp portion 21 clamp and fix the product a. Meanwhile, the first supporting member 31 and the second supporting member 32 are driven to be away from each other by the linkage assembly 40 until the clamping position is withdrawn to release the support of the product a. When the clamping of the product A needs to be released, the movable clamping part 22 is controlled to move away from the fixed clamping part 21 so as to release the product A. Meanwhile, the first supporting member 31 and the second supporting member 32 are driven to approach each other by the linkage assembly 40 until the first supporting member and the second supporting member extend into the clamping position, so as to support the product a and prevent the product a from falling.

So, utilize movable clamping part 22 and fixed clamping part 21 centre gripping product A, and utilize first support piece 31 and the second support piece 32 that link with movable clamping part 22 to support product A, operating personnel control movable clamping part 22 presss from both sides tightly or loosens and can accomplish the clamping, goes up the unloading convenient and fast, is favorable to improving clamping efficiency.

In the embodiment of the present invention, the clamping assembly 20 further includes an operating member 23, where the operating member 23 is disposed on the mounting bracket 10 and located on a side of the movable clamping portion 22 away from the fixed clamping portion 21. The operating member 23 is movable in a first direction X to a clamped position (see fig. 2) and an undamped position (see fig. 1) under the influence of an external force. When the operating member 23 is moved to the clamping position, the operating member 23 abuts against the movable clamping portion 22, so that the movable clamping portion 22 moves toward the fixed clamping portion 21 to clamp the clamped product a. When the operating member 23 is moved to the release position, the operating member 23 drives the movable clamping portion 22 to move away from the fixed clamping portion 21, so that the movable clamping portion 22 and the fixed clamping portion 21 release the clamping of the product a.

Thus, when the product a needs to be clamped, first, the operating member 23 is pushed to move to the releasing position along the first direction X, and the operating member 23 drives the movable clamping portion 22 to move away from the fixed clamping portion 21, so that the first supporting member 31 and the second supporting member 32 are driven to approach each other through the linkage assembly 40 until the first supporting member and the second supporting member extend into the clamping position. At this time, the product a can be placed in the clamping position, and the first supporting member 31 and the second supporting member 32 are used to support the product a, so as to prevent the product a from falling. Then, the operating member 23 is pushed to move to the clamping position in the first direction X, at which time the operating member 23 abuts against the movable clamping portion 22, so that the movable clamping portion 22 moves close to the fixed clamping portion 21 until the movable clamping portion 22 and the fixed clamping portion 21 clamp and fix the product a. At the same time, the first supporting member 31 and the second supporting member 32 are driven to move away from each other by the linkage assembly 40 until the clamping position is withdrawn to release the support of the product a.

When the clamping of the product A needs to be released, the operating member 23 is pushed to move to the release position, so that the operating member 23 drives the movable clamping part 22 to move away from the fixed clamping part 21 to release the product A. Meanwhile, the first supporting member 31 and the second supporting member 32 are driven to approach each other by the linkage assembly 40 until the first supporting member and the second supporting member extend into the clamping position, so as to support the product a and prevent the product a from falling. That is, by pushing the operating member 23 to move between the releasing position and the clamping position, the clamping and releasing of the product a are realized, the operation is convenient and quick, and the clamping efficiency is improved.

The movement of the operating element 23 between the release position and the clamping position is not limited to being performed by pushing and pulling by an operator, but may be performed by automation. For example, in one embodiment, the clamping assembly 20 further includes a first drive member mounted to the mounting bracket 10 and drivingly coupled to the operating member 23 to drive the operating member 23 in the first direction X between the undamped position and the clamped position. Alternatively, the first driving member may be a cylinder or the like.

In particular, in the embodiment, the clamping assembly 20 further includes a first elastic member 24, and the first elastic member 24 is disposed on a side of the movable clamping portion 22 facing the operating member 23. When the operating member 23 is moved to the clamping position, the operating member 23 abuts against the movable clamping portion 22 through the first elastic member 24 (at this time, the first elastic member 24 is in a compressed state) to push the movable clamping portion 22 to clamp the product a, and to provide a clamping force to the movable clamping portion 22 to hold the clamped product a. When the operating member 23 moves to the releasing position, the operating member 23 is separated from the first elastic member 24 (the first elastic member 24 is in a natural state at this time), and drives the movable clamping portion 22 to move away from the fixed clamping portion 21, i.e. the clamping force for driving the movable clamping portion 22 to clamp the product a disappears, and the movable clamping portion 22 releases the clamping of the product a. So, the size of the clamping force of clamping product A can be adjusted by selecting the first elastic pieces 24 with different specifications to be suitable for clamping different types of products A, and the compatibility of the detection jig is improved. Alternatively, the first elastic member 24 may be a spring.

Further, the clamping assembly 20 further includes a first guiding rod 25 and a first slider 26, the first guiding rod 25 is fixedly connected to the mounting bracket 10, the first slider 26 and the operating member 23 are slidably connected to the first guiding rod 25, and the movable clamping portion 22 is fixedly connected to the first slider 26. The first guide rod 25 is parallel to the first direction X, so that the first slider 26 and the operating member 23 slide along the first guide rod 25, i.e., move along the first direction X. One or more movable holding portions 22 may be provided on the first slider 26, as long as the product a can be held stably, which is not limited herein. Similarly, the fixed holding portion 21 may include one or more, as long as it can hold the product a stably, which is not limited herein.

It should be noted that, according to the shape of the product a to be clamped, the positions of the movable clamping portion 22 and the fixed clamping portion 21 may be designed to match the shape of the product a, so as to ensure that the product a can be clamped stably. For example, the product a may have a rectangular, circular, oval, etc., and is not limited herein.

Further, the clamping assembly 20 further comprises a pull rod 27, one end of the pull rod 27 is fixedly connected with the first sliding block 26, and the other end of the pull rod 27 is in sliding fit with the operating piece 23. The first elastic member 24 is sleeved on the pull rod 27 and is located between the first slider 26 and the operating member 23. Thus, when the operating member 23 moves to the clamping position, the operating member 23 abuts against the first slider 26 through the first elastic member 24, so as to drive the movable clamping portion 22 to clamp the product a. When the operating member 23 is moved to the release position, the operating member 23 drives the first slider 26 and the movable clamping portion 22 to move away from the fixed clamping portion 21 via the pull rod 27, thereby releasing the clamping of the product a.

In particular, in the embodiment, the linkage assembly 40 includes a first linkage mechanism 41, and the first linkage mechanism 41 includes a first linkage block 410 and a first cam slot plate 411. The first linkage block 410 is movably connected to the mounting bracket 10 along the first direction X and is fixedly connected to the operating member 23, such that the first linkage block 410 can move along the first direction X following the operating member 23. The first cam groove plate 411 is mounted to the first linkage block 410, and opens the first cam groove B1. The first support 31 has mounted thereon a first follower 34, and the first follower 34 is slidably fitted in the first cam groove B1. When the operating member 23 moves between the clamping position and the releasing position, the operating member 23 drives the first linkage block 410 and the first cam slot plate 411 to move along the first direction X, so that the first follower 34 moves along the first cam slot B1 relative to the first cam slot plate 411, and further drives the first supporting member 31 to move close to or away from the second supporting member 32. That is, the linear motion of the operating member 23 in the first direction X is converted into the linear motion of the first supporting member 31 in the second direction Y by the sliding fit of the first follower 34 with the first cam groove B1. Alternatively, the first follower 34 may be a rolling bearing, thereby reducing friction between the first follower 34 and the first cam slot plate 411, so that the first follower 34 can smoothly move along the first cam slot plate 411.

In the embodiment, the support assembly 30 further includes a second guide rod 331 and a first mounting block 33, and the second guide rod 331 is fixedly connected to the mounting bracket 10 and parallel to the second direction Y. The first mounting block 33 is slidably coupled to the second guide bar 331. The first support 31 and the first follower 34 are mounted on the first mounting block 33. When the first cam slot 411 moves along the first direction X along with the first linkage block 410, the first follower 34 and the first cam slot B1 cooperate to drive the first mounting block 33 to slide along the second guide rod 331, so that the first supporting member 31 moves along with the first mounting block 33 to support or release the product a. One or more first supporting members 31 may be attached to the first attaching block 33 as needed, so long as the product a can be stably supported, and the present invention is not limited thereto.

In the embodiment, the first linkage mechanism 41 further includes a second elastic member 412, where one end of the second elastic member 412 is connected to the mounting bracket 10, and the other end of the second elastic member is connected to the first linkage block 410, so as to provide a pre-tightening force for driving the operating member 23 to move from the releasing position to the clamping position. Thus, when feeding into the clamping position is required (as shown in fig. 3 and 4), the operator pushes the operating member 23 from the clamping position to the releasing position, and the second elastic member 412 is in a stretched state, so that the product a can be placed on the first supporting member 31 and the second supporting member 32 in the clamping position. When the product a needs to be clamped (as shown in fig. 5 and 6), the operator releases the operating member 23, and the operating member 23 automatically moves to the clamping position under the elastic force of the second elastic member 412, so that the movable clamping portion 22 and the fixed clamping portion 21 clamp the product a.

Further, the first interlocking mechanism 41 further includes a first locking fitting 413 and a first locking piece 414. The first locking fitting 413 is mounted on the first linkage block 410 to move along the first direction X with the first linkage block 410. The first locking member 414 is provided on the mounting bracket 10 and has a first locking portion 4141 (see fig. 8) and a second locking portion 4142 (see fig. 8).

When the operating member 23 is moved to the release position, the first locking member 414 is operable to bring the first locking portion 4141 into positive engagement with the first locking engagement member 413; when the operating member 23 is moved to the clamping position, the first locking member 414 is operable to bring the second locking portion 4142 into positive engagement with the first locking engagement member 413. In this way, the first locking portion 4141 of the first locking member 414 is in a limit fit with the first locking engagement member 413 to limit the movement of the first linkage block 410 in the first direction X, thereby locking the operating member 23 in the release position. The second locking portion 4142 of the first locking member 414 is used to limit the movement of the first linkage block 410 in the first direction X by being engaged with the first locking engagement member 413, thereby locking the operating member 23 in the clamping position. That is, the first locking engagement piece 413 and the first locking piece 414 can achieve locking of the position of the operating piece 23, preventing the product a from falling.

Further, the first locking member 414 is rotatably coupled to the mounting bracket 10, and the first locking member 414 includes a first locked position and a first unlocked position during rotation. When the first locking member 414 is rotated to the first locking position, the first locking engagement member 413 is in a limit engagement with the first locking portion 4141 or the second locking portion 4142 to prevent the first linkage block 410 from moving in the first direction X, thereby locking the operating member 23 in the clamped position or the unclamped position. When the first locking piece 414 is rotated to the first unlocking position, the first locking fitting 413 is separated from the first locking portion 4141 or the second locking portion 4142, thereby releasing the restriction of the movement of the first linkage block 410 in the first direction X, so that the operating piece 23 can be moved between the clamping position and the releasing position.

Further, the first locking matching piece 413 has a first head 4131, the first locking portion 4141 is a first limiting groove formed on the first locking piece 414, and the second locking portion 4142 is a second limiting groove formed on the first locking piece 414. When the first locking member 414 is rotated to the first locking position, the first head 4131 is restricted within the first restricting groove or the second restricting groove. When the first locking member 414 is rotated to the first unlocking position, the first head 4131 exits the first limit groove or the second limit groove.

Further, the first interlocking mechanism 41 further includes a first torsion spring (not shown) fitted between the first locking member 414 and the mounting bracket 10 for providing a preload force for rotating the first locking member 414 from the first unlocking position to the first locking position. In this way, when the lock of the operating member 23 needs to be released, the operator presses the first locking member 414, so that the first locking member 414 rotates to the first unlocking position against the elastic force of the first torsion spring, thereby releasing the lock of the operating member 23, so that the operating member 23 can move between the releasing position and the clamping position. When the operating member 23 needs to be locked, the operator releases the first locking member 414, so that the first locking member 414 automatically rotates to the first locking position under the elastic force of the first torsion spring, and the first head 4131 is limited in the first limiting groove or the second limiting groove, thereby limiting the operating member 23 to the release position or the clamping position.

With continued reference to fig. 1 and 2, in an embodiment of the present invention, the linkage assembly 40 includes a second linkage mechanism 42, and the second linkage mechanism 42 includes a second linkage block 420 and a second cam slot plate 421. The second linkage block 420 is movably connected to the mounting bracket 10 along the first direction X and is fixedly connected to the operating member 23, so that the second linkage block 420 can move along the first direction X along the operating member 23. The second cam groove plate 421 is mounted on the second linkage block 420, and is provided with a second cam groove B2. A second follower (not shown) is mounted on the second support 32, and slidably engages with the second cam groove B2. When the operating member 23 moves between the clamping position and the releasing position, the operating member 23 drives the second linkage block 420 and the second cam slot plate 421 to move along the first direction X, so that the second follower moves along the second cam slot plate 421 relative to the second cam slot plate 421, and further drives the second support member 32 to move close to or away from the first support member 31. That is, the linear motion of the operating member 23 in the first direction X is converted into the linear motion of the second support member 32 in the second direction Y by the sliding fit of the second follower with the second cam groove B2. Alternatively, the second follower may be a rolling bearing, thereby reducing friction between the second follower and the second cam groove plate 421 so that the second follower can smoothly move along the second cam groove plate 421.

In the embodiment, the support assembly 30 further includes a third guide rod (not shown) and a second mounting block 35, wherein the third guide rod is fixedly connected to the mounting bracket 10 and is parallel to the second direction Y. A second mounting block 35 is slidably connected to the third guide bar, and a second support 32 and a second follower are mounted on the second mounting block 35. When the second cam slot plate 421 moves along the first direction X along the second linkage block 420, the second follower and the second cam slot B2 cooperate to drive the second mounting block 35 to slide along the third guide rod, so that the second supporting member 32 moves along the second mounting block 35 to support or release the product a. One or more second support members 32 may be mounted on the second mounting block 35 as needed, so long as the product a can be stably supported, and the present invention is not limited thereto.

In the embodiment, the second linkage mechanism 42 further includes a third elastic member 422, where one end of the third elastic member 422 is connected to the mounting bracket 10, and the other end of the third elastic member is connected to the second linkage block 420, so as to provide a pre-tightening force for driving the operating member 23 to move from the releasing position to the clamping position. Thus, when the feeding to the clamping position is required, the operator pushes the operating member 23 from the clamping position to the releasing position, and the third elastic member 422 is in a stretched state, so that the product a can be placed on the first supporting member 31 and the second supporting member 32 in the clamping position. When the product a needs to be clamped, the operator releases the operating member 23, and the operating member 23 automatically moves to the clamping position under the action of the elastic force of the second elastic member 412, so that the movable clamping portion 22 and the fixed clamping portion 21 clamp the product a.

Further, the second interlocking mechanism 42 further includes a second locking mating piece 423 and a second locking piece 424. The second locking matching piece 423 is installed on the second linkage block 420 to move along the first direction X along with the second linkage block 420. The second locking piece 424 is provided on the mounting bracket 10, and has a third locking portion 4241 and a fourth locking portion 4242.

When the operating member 23 is moved to the release position, the second locking member 424 is operable to bring the third locking portion 4241 into positive engagement with the second locking engagement member 423; the second locking member 424 is operable to positively engage the fourth locking portion 4242 with the second locking engagement member 423 when the operating member 23 is moved to the clamping position. In this way, the third locking portion 4241 of the second locking member 424 is in limit fit with the second locking mating member 423 to limit the movement of the second linking block 420 in the first direction X, thereby locking the operating member 23 in the release position. The fourth locking portion 4242 of the second locking member 424 is in limit fit with the second locking mating member 423 to limit the movement of the second linkage block 420 in the first direction X, thereby locking the operating member 23 in the clamping position. That is, the second locking engagement piece 423 and the second locking piece 424 can achieve locking of the position of the operating piece 23, preventing the product a from falling.

Further, the second locking member 424 is rotatably coupled to the mounting bracket 10, and the second locking member 424 includes a second locked position and a second unlocked position during rotation. When the second locking member 424 rotates to the second locking position, the second locking engagement member 423 is in a limit engagement with the third locking portion 4241 or the fourth locking portion 4242 to prevent the second linkage block 420 from moving in the first direction X, thereby locking the operating member 23 in the clamping position or the releasing position. When the second locking piece 424 is rotated to the second unlocking position, the second locking fitting 423 is separated from the third locking portion 4241 or the fourth locking portion 4242, thereby releasing the restriction of the movement of the second linkage block 420 in the first direction X, so that the operating piece 23 can be moved between the clamping position and the releasing position.

Further, the second locking mating member 423 has a second head 42331, the third locking portion 4241 is a third limiting groove formed on the second locking member 424, and the fourth locking portion 4242 is a fourth limiting groove formed on the second locking member 424. When the second locking member 424 is rotated to the second locking position, the second head 42331 is limited to the third or fourth limit groove. When the second locking member 424 is rotated to the second unlocking position, the second head 42331 is withdrawn from the third or fourth limiting groove.

Further, the second interlock mechanism 42 also includes a second torsion spring (not shown) fitted between the second locking member 424 and the mounting bracket 10 for providing a preload force that rotates the second locking member 424 from the second unlocked position to the second locked position. In this way, when the lock of the operating member 23 needs to be released, the operator presses the second locking member 424 so that the second locking member 424 rotates to the second unlocking position against the elastic force of the second torsion spring, thereby releasing the lock of the operating member 23 so that the operating member 23 can move between the releasing position and the clamping position. When the operating member 23 needs to be locked, the operator releases the second locking member 424, so that the second locking member 424 automatically rotates to the second locking position under the elastic force of the second torsion spring, and the second head 42331 is limited in the third limit groove or the fourth limit groove, thereby locking the operating member 23 in the release position or the clamping position.

Further, the linkage assembly 40 further includes a pressing plate 43, and the pressing plate 43 is mounted on the first locking member 414 and the second locking member 424. When the pressing plate 43 is pressed, the first locking member 414 is driven to rotate to the first unlocking position, and the second locking member 424 is driven to rotate to the second unlocking position. When the pressing plate 43 is released, the first locking member 414 rotates to the first locking position by the first torsion spring, and simultaneously the second locking member 424 rotates to the second locking position by the second torsion spring. The pressing operation of the pressing plate 43 is not limited to the pressing operation by the operator, and may be performed by an automated method. For example, in one embodiment, the linkage assembly 40 further includes a second driving member mounted to the mounting bracket 10 and drivingly connected to the pressing plate 43 to drive the pressing plate 43 to move, thereby rotating the first locking member 414 between the first unlocked position and the first locked position and simultaneously rotating the second locking member 424 between the second unlocked position and the second locked position. Alternatively, the second driving member may be a cylinder or the like.

Further, the linkage assembly 40 further includes a first handle 11 and a second handle 12, the first handle 11 and the second handle 12 are fixedly connected to both ends of the mounting bracket 10 in the first direction X, and the operating member 23 is disposed adjacent to the first handle 11, and the pressing plate 43 is disposed adjacent to the second handle 12. In this way, the operator can hold the first handle 11 and the second handle 12 and conveniently operate the operating member 23 and the pressing plate 43, thereby achieving the clamping of the product a.

In particular, in the embodiment, the detection fixture further includes a pressing assembly 50, and the pressing assembly 50 includes a support plate 51, a pressing block 52, and a cam block 53. The support plate 51 is mounted to the mounting bracket 10 for supporting the flexible circuit board a of the product a in the clamped position. The press block 52 is rotatably coupled to the mounting bracket 10 and includes a first position (see fig. 1) for pressing the flexible circuit board a and a second position (see fig. 4) for releasing the flexible circuit board a during rotation.

The cam block 53 is connected to the second linkage block 420 and is in driving engagement with the press block 52. When the operating member 23 is moved to the clamped position, the cam block 53 moves with the second linkage block 420 and drives the pressing block 52 to rotate to the first position. When the operating member 23 is moved to the released position, the cam block 53 moves with the second linkage block 420 and urges the pressing block 52 to rotate to the second position. Thus, when the operating member 23 is moved to the release position, the cam block 53 urges the pressing block 52 to rotate to the second position such that the flexible electronic control board on the product a is located on the support plate 51 when the product a is placed on the first and

second supports

31, 32 in the clamping position. When the operating member 23 is moved to the clamping position, the cam block 53 drives the pressing block 52 to rotate to the first position such that the pressing block 52 presses the flexible circuit board a on the product a against the support plate 51.

Further, the pressing assembly 50 further includes a magnetic attraction member (not shown) provided on the mounting bracket 10 or the support plate 51 for attracting and fixing the pressing block 52 in the first position so that the pressing block 52 presses the flexible circuit board a of the product a on the support plate 51. Alternatively, the magnetic attraction member may be a magnet.

It should be noted that, a connector such as a probe may be further disposed on the supporting board 51, and used for electrically connecting with the flexible circuit board on the supporting board 51, so as to detect the product a.

The clamping process of the detection jig of the present invention is described below with reference to fig. 3 to 8:

please refer to fig. 3 to 6, the feeding of the product a: first, the operator right-hand presses the pressing plate 43 so that the first locking piece 414 rotates upward to the first unlocking position, while the second locking piece 424 rotates upward to the second unlocking position.

Then, the operator pulls the operating member 23 leftward to the release position, so that the movable clamp portion 22 moves leftward. Meanwhile, the first linkage block 410 drives the first cam slot plate 411 to move leftwards (the second elastic member 412 stretches), so that the first follower 34 moves along the first cam slot B1 relative to the first cam slot plate 411, and the second linkage block 420 drives the second cam slot plate 421 to move leftwards (the third elastic member 422 stretches), so that the second follower moves along the second cam slot B2 relative to the second cam slot plate 421, and further drives the first supporting member 31 and the second supporting member 32 to approach each other and extend into the clamping position. At the same time, cam block 53 moves leftward with second linkage block 420, thereby urging press block 52 to rotate upward to the second position.

Then, the operator releases the pressing plate 43 (both the first locking member 414 and the second locking member 424 are rotated downward) with the right hand so that the first head 4131 is positioned in the first locking groove of the first locking member 414 and the first head 4131 is positioned in the third locking groove of the second locking member 424 to lock the operating member 23 in the released position. The operator places the product a on the first 31 and second 32 supports in the gripping position.

Then, the pressing plate 43 is pressed by the right hand of the operator, and the operating member 23 is released by the left hand, so that the operating member 23 automatically moves rightward to the clamping position under the action of the second elastic member 412 and the third elastic member 422, and the movable clamping portion 22 and the fixed clamping portion 21 clamp the product a. Meanwhile, the first linkage block 410 moves rightward, so that the first follower 34 moves along the first cam groove B1 relative to the first cam groove plate 411, and the second linkage block 420 moves rightward, so that the second follower moves along the second cam groove B2 relative to the second cam groove plate 421, and further drives the first supporting member 31 and the second supporting member 32 to move away from each other, and the support of the product a is released. Meanwhile, the second linkage block 420 drives the cam block 53 to move rightward, so that the pressing block 52 rotates to the first position under the adsorption action of the magnetic attraction piece, that is, the pressing block 52 presses the flexible circuit board a of the product a on the supporting plate 51.

Finally, the operator releases the pressing plate 43, so that the first locking member 414 rotates to the first locking position, and the second locking member 424 rotates to the second locking position, at which time the first head 4131 is located in the second locking groove of the first locking member 414, and the second head 42331 is located in the fourth locking groove of the second locking member 424, to lock the operating member 23 in the clamping position, preventing the product a from falling.

And (3) detecting a product A: the operator can check the front and back of the product A, check the backlight, check the light transmission, etc. according to the process requirement.

Referring to fig. 7 and 8, product a is fed: first, the operator presses the pressing plate 43 with the right hand and pulls the operating member 23 to the left to the release position with the left hand, so that the movable clamp portion 22 releases the clamping of the product a. Meanwhile, the first linking block 410 and the second linking block 420 move leftwards, respectively, and drive the first supporting member 31 and the second supporting member 32 to move close to each other to support the product a, and the product a is placed to drop.

Then, the pressing plate 43 is released by the right hand of the worker so that the operating member 23 is locked in the released position. At this time, the operator can take down the product a supported on the first support 31 and the second support 32.
