In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] In the embodiment of the first aspect of the present application, the FPC tensioning device is used to tension the FPC 600, referring to Figures 1-3 comprises a first body 100 and at least three stretching devices 200, the first body 100 comprises a placing part 110 for loading the FPC 600; each stretching device 200 is uniformly distributed on the edge of the placing part 110, the stretching device 200 comprises a clamping mechanism 210 and a second body 220, the clamping mechanism 210 is used to clamp the FPC 600, the second body 220 is rotationally connected to the first body 100, and the rotation axis of the second body 220 is perpendicular to the first body 100, along the direction of the second body 220 towards the placing part 110, the clamping mechanism 210 is slidingly connected to the second body 220, and the clamping mechanism 210 can be away from or close to the FPC 600 to tension the FPC 600; the stretching device 200 comprises a first fixing part 230 and a second fixing part 240, the first fixing part 230 is detachably connected to the clamping mechanism 210 and the second body 220, and the first fixing part 230 can lock or release the clamping mechanism 210 and the second body 220; the second fixing part 240 is detachably connected to the first body 100 and the second body 220, and the second fixing part 240 can lock or release the first body 100 and the second body 220.

[0043] Since the clamping mechanism 210 can move away from or close to the FPC 600 along the direction of the stretching device 200 towards the placement portion 110, and the stretching device 200 can rotate relative to the first main body 100, thus, along the direction of the stretching device 200 towards the placement portion 110, with the maximum extension of the single clamping mechanism 210 as the radius, the area where the circumference formed by the rotation of the stretching device 200 relative to the first main body 100 with the radius overlaps with the placement portion 110 can be clamped by the clamping mechanism 210, therefore, at least three stretching devices 200 are evenly distributed along the edge of the placement portion 110, so that the circumference formed by the rotation of all the stretching devices 200 relative to the first main body 100 can overlap the entire placement portion 110, thus realizing that each corner of the irregular FPC 600 on the placement portion 110 can be clamped by the stretching device 200. Therefore, since the stretching device 200 can rotate relative to the first main body 100 and the clamping mechanism 210 can move relative to the second main body 220, the adjustment of the stretching device 200 is more flexible, the range covered is larger, and it can be applied to special-shaped FPC 600.

[0044] Specifically, the special-shaped FPC 600 is placed on the placement portion 110, each stretching device 200 is adjusted, including rotating the clamping mechanism 210 and adjusting the clamping mechanism 210 to move close to the FPC 600, so that each clamping mechanism 210 clamps the corner of the corresponding FPC 600, then, according to the needs, it is selected whether to tighten the FPC 600 by adjusting the clamping mechanism 210 to move away from the FPC 600, after each clamping mechanism 210 is adjusted to the appropriate position, the first fixing part 230 on each stretching device 200 is adjusted to lock the corresponding clamping mechanism 210 and the second main body 220, so as to limit the sliding of the clamping mechanism 210 along the direction of the stretching device 200 towards the placement portion 110, and the second fixing part 240 on each stretching device 200 is adjusted to lock the corresponding second main body 220 and the first main body 100, so as to limit the rotation of the corresponding stretching device 200 to the first main body 100, thereby realizing the tightening of the FPC 600 on the placement portion 110.

[0045] In order to provide an implementation manner of the first fixing part 230 locking or releasing the clamping mechanism 210 and the second main body 220, referring to Figure 1 and Figure 2 , the clamping mechanism 210 includes a telescopic part 211, the telescopic part 211 is slidingly connected to the second main body 220 along the direction of the second main body 220 towards the placement portion 110, the first fixing part 230 is inserted into the second main body 220 along the direction perpendicular to the movement direction of the telescopic part 211, and can move relative to the telescopic part 211 to abut against the surface of the telescopic part 211 or away from the telescopic part 211, specifically, the first fixing part 230 is threadedly connected to the second main body 220.

[0046] When it is needed to lock the second body 220 and the clamping mechanism 210, the first fixing member 230 is rotated to move towards the telescopic member 211 and abut against the surface of the telescopic member 211, thus the telescopic member 211 is clamped on the second body 220 by the extrusion of the second body 220 and the first fixing member 230; when it is needed to adjust the telescopic member 211, the first fixing member 230 is rotated to move away from the telescopic member 211, thus the telescopic member 211 is released from the second body 220 and can slide relative to the second body 220.

[0047] In order to provide an implementation mode of the second fixing member 240 locking the first body 100 and the second body 220, referring to Figure 1 The second body 220 is provided with an arc-shaped slot 221 along the surface parallel to the placement portion 110, the arc-shaped slot 221 is arc-shaped, the arc-shaped slot 221 is coaxial with the rotation axis of the second body 220, the second fixing member 240 is arranged through the arc-shaped slot 221, the second fixing member 240 can lock or release the second body 220 from the first body 100, specifically, the second fixing member 240 is arranged through the second body 220 and is threadedly connected to the first body 100, the end of the second fixing member 240 away from the first body 100 protrudes along the radial direction of the second fixing member 240, the protruding part can abut against the surface of the second body 220 away from the first body 100.

[0048] When it is needed to lock the first body 100 and the second body 220, the second fixing member 240 is rotated to move the end of the second fixing member 240 away from the first body 100 to be close to the first body 100 and make the protruding part of the second fixing member 240 abut against the surface of the second body 220, thus the second body 220 is clamped and locked by the protruding part of the second fixing member 240 and the first body 100; when it is needed to release the first body 100 and the second body 220, the second fixing member 240 is rotated to move the end of the second fixing member 240 away from the first body 100, thus the first body 100 and the second body 220 are released.

[0049] In some embodiments, the plurality of inner side walls 130 of the first body 100 are sequentially connected to be polygonal and define the placement portion 110, for example Figure 1The inner side wall 130 in the first body 100 is square, and the stretching device 200 can rotate relative to the first body 100 during use, so the stretching device 200 is preferably arranged at the included angle of the inner side wall 130 to improve the clamping range of the stretching device 200 on the placement part 110 (if arranged at the edge of the inner side wall 130, the rotation angle of the stretching device 200 and the extension length of the telescopic part 211 need to be increased to clamp the FPC 600 at the included angle of the adjacent inner side wall 130). Therefore, in order to further improve the tensioning effect of the FPC tensioning device on the FPC 600, referring to Figure 1 and Figure 3 , the FPC tensioning device further comprises a plurality of clamping devices 300, the stretching device 200 and the clamping device 300 are alternately distributed along the circumference of the placement part 110, the stretching device 200 is not collinear with the two clamping devices 300 located on both sides of the stretching device 200, and the clamping device 300 can clamp the FPC 600; the clamping device 300 comprises a third body 310, a clamping mechanism 320 and a third fixing part 340, the clamping mechanism 320 is slidingly connected to the third body 310 in the direction of the placement part 110 along the clamping device 300, the clamping mechanism 320 can clamp the FPC 600, and the clamping mechanism 320 can move close to or away from the FPC 600 to tension the FPC 600; the third fixing part 340 is detachably connected to the clamping mechanism 320 and the third body 310, and the third fixing part 340 can lock or release the clamping mechanism 320 and the third body 310.

[0050] The embodiment of the application adds a plurality of clamping devices 300 on the placement part 110 defined by the inner side wall 130 of the first body 100 in polygonal shape (hereinafter referred to as "polygonal shape"), specifically, the stretching device 200 is arranged at the included angle of each connected inner side wall 130, and one clamping device 300 is arranged between two adjacent stretching devices 200 to further tension the FPC 600.

[0051] Further, each clamping device 300 is installed on each side of the polygon, the moving part 330 is adjusted to move the clamping part 400 close to the FPC 600, when the clamping part 400 can clamp the FPC 600, the clamping part 400 is adjusted to clamp the FPC 600, then the moving part 330 is adjusted in the direction away from the FPC 600 to stretch the FPC 600, and finally the third fixing part 340 is adjusted to lock the moving part 330 to clamp and stretch the FPC 600.

[0052] It can be understood that after the stretching device 200 stretches the FPC 600 at the corners of the polygon, the clamping device 300 is used to further stretch the FPC 600. It should be noted that the order of stretching the FPC 600 is not limited to using the stretching device 200 first or the clamping device 300 first.

[0053] To provide a third fixing member 340 to achieve the locking or releasing of the moving member 330 and the third body 310, in some embodiments, referring to Figure 3 and Figure 4 The clamping mechanism 320 includes a moving member 330, and the third fixing member 340 passes through the moving member 330, and the third fixing member 340 can lock or release the moving member 330 to the third body 310. Specifically, the third fixing member 340 passes through the moving member 330 and is threadedly connected to the third body 310, and the end of the third fixing member 340 away from the third body 310 protrudes along the radial direction of the third fixing member 340, and the protruding part can abut against the surface of the moving member 330 away from the third body 310.

[0054] When it is necessary to lock the moving member 330 and the third body 310, the third fixing member 340 is screwed, so that the protruding part of the third fixing member 340 abuts against the surface of the moving member 330, thereby locking the third body 310 and the moving member 330; when it is necessary to release the moving member 330 and the third body 310, the third fixing member 340 is unscrewed, so that the protruding part of the third fixing member 340 abutting against the surface of the moving member 330 moves away from the moving member 330, thereby releasing the moving member 330 to the third body 310.

[0055] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5 The clamping device 300 includes a fourth fixing member 350, the first body 100 is provided with a groove 120, the groove 120 extends along one of the stretching devices 200 to the direction of the adjacent other stretching device 200, the fourth fixing member 350 passes through the third body 310 and the groove 120, the third body 310 is slidingly connected to the first body 100 along the extension direction of the groove 120, and the fourth fixing member 350 can lock or release the first body 100 and the third body 310.

[0056] Specifically, the embodiment provides a way to lock or release the first body 100 and the second body 220 by the fourth fixing member 350, referring to Figure 4 and Figure 5The first body 100 is provided with a mounting plate 360 on the side away from the third body 310, the mounting plate 360 abuts against the first body 100, the fourth fixing member 350 is sequentially arranged through the third body 310 and the first body 100 and is threadedly connected to the mounting plate 360, the end of the fourth fixing member 350 away from the mounting plate 360 protrudes along the radial direction of the second fixing member 240, and the protruding part can abut against the surface of the third body 310 away from the first body 100. It can be understood that in some other embodiments, the fourth fixing member 350 can also be arranged through the groove 120 and threadedly connected to the third body 310, and the fourth fixing member 350 can be released or locked with the first body 100 and the third body 310 by loosening or tightening, which will not be described in detail here.

[0057] Taking two stretching devices 200 on one side of the polygon and the clamping device 300 between the two stretching devices 200 as an example, when one of the stretching devices 200 clamps the FPC 600 close to the side of the stretching device 200, the clamping device 300 moves close to the stretching device 200 to adapt to the shape of the FPC 600, and the clamping member 400 clamps the FPC 600 by adjusting the moving direction of the moving member 330. The other stretching device 200 moves close to the FPC 600 by rotating and extending the stretching member 211 relative to the first body 100, so that the clamping member 400 on the stretching device 200 clamps the FPC 600. By adjusting the positions of the clamping members 400 on the two stretching devices 200 and the clamping member 400 on the clamping device 300 in the placing part 110, the FPC 600 is stretched on the side of the polygon. In other words, by cooperating the rotation of the stretching device 200 and the movement of the clamping device 300, when the clamping device 300 moves close to one of the stretching devices 200 to adapt to the shape of the FPC 600, the other stretching device 200 can compensate for the distance between the clamping device 300 and the other stretching device 200 by rotating, so that the two can adapt to the special-shaped FPC 600.

[0058] When it is needed to lock the third body 310 on the first body 100, the fourth fixing member 350 is tightened to move the mounting plate 360 close to the first body 100, and the protruding part of the fourth fixing member 350 moves towards the third body 310, so that the mounting plate 360 and the protruding part of the fourth fixing member 350 clamp the first body 100 and the third body 310; when it is needed to adjust the position of the clamping device 300 on the side of the polygon, the fourth fixing member 350 is loosened to change the mounting plate 360 and the protruding part of the fourth fixing member 350 from the clamping state to the releasing state, so as to release the first body 100 and the third body 310. After the third body 310 is moved to the required position along the extension direction of the groove 120, the third body 310 is locked on the first body 100.

[0059] Further, in order to improve the adjustment accuracy of the stretching device 200 and the clamping device 300, in some embodiments, the present embodiment is provided with a scale 500 on the telescopic member 211 along the telescopic direction of the telescopic member 211, a scale 500 on the second main body 220 near the side of the arc-shaped slot 221 along the extension direction of the arc-shaped slot 221, and a scale 500 on the moving member 330 along the moving direction of the moving member 330. Figure 1

[0060] In order to provide a clamping mode of the stretching device 200 and the clamping device 300 to the FPC 600, in some embodiments, the present embodiment is provided with a clamping mechanism 210 and a clamping mechanism 320, and the clamping mechanism 210 and the clamping mechanism 320 are both provided with a clamping member 400. Figure 1 Figure 2 Figure 3 Figure 6 The clamping member 400 includes a first clamping part 410 and a second clamping part 420, and the first clamping part 410 is connected to the second clamping part 420 and can move relative to the second clamping part 420 to clamp or release the FPC 600. Specifically, the clamping member 400 on the stretching device 200 is connected to the telescopic member 211, and the clamping member 400 on the clamping mechanism 320 is connected to the moving member 330.

[0061] Since the first clamping part 410 is connected to the second clamping part 420, when it is necessary to clamp the FPC 600, the present embodiment is taken as an example that the first clamping part 410 moves along the second clamping part 420 in the direction of the first clamping part 410, the first clamping part 410 is operated to move away from the second clamping part 420, the part of the FPC 600 that needs to be clamped is positioned between the first clamping part 410 and the second clamping part 420, and the first clamping part 410 is operated to move close to the second clamping part 420 and clamp the FPC 600 with the first clamping part 410 and the second clamping part 420. Figure 6

[0062] It can be understood that when the first clamping part 410 and the second clamping part 420 are not in the operating state, the surface of the first clamping part 410 that can clamp the FPC 600 abuts against the surface of the second clamping part 420 that can clamp the FPC 600.

[0063] ​​​​​In the embodiment, a spring is arranged on the side of the first clamping part 410 away from the second clamping part 420, one end of the spring abuts against the surface of the first clamping part 410 away from the second clamping part 420, when the first clamping part 410 moves away from the second clamping part 420, the first clamping part 410 exerts pressure on the spring to make the spring contract, when the first clamping part 410 needs to move close to the second clamping part 420, the first clamping part 410 is loosened, and the spring and the first clamping part 410 are reset. In other embodiments, threaded connection can also be used to achieve clamping or releasing of the FPC 600 by the first clamping part 410 and the second clamping part 420, for example, a bolt is arranged in the first clamping part 410 and the second clamping part 420, by loosening the bolt, the first clamping part 410 can move away from the second clamping part 420, and the FPC 600 can be placed between the first clamping part 410 and the second clamping part 420; by tightening the bolt, the first clamping part 410 moves close to the second clamping part 420 and abuts against the second clamping part 420 to clamp the FPC 600.

[0065] Taking the example that the protruding part 430 is connected to the second clamping part 420 and the first clamping part 410 is provided with the through hole 440, when the FPC 600 needs to be clamped, the first clamping part 410 is operated to move away from the second clamping part 420, so that the protruding part 430 is away from the through hole 440, then the protruding part 430 is arranged in the hole of the FPC 600, then the first clamping part 410 is operated to move close to the second clamping part 420, and the protruding part 430 passes through the through hole 440, so that the second clamping part 420 and the first clamping part 410 clamp the FPC 600.

[0066] In some embodiments, referring to Figure 7 , the first clamping part 410 is rotationally connected to the second clamping part 420, and the rotation axis of the first clamping part 410 relative to the second clamping part 420 is parallel to the sliding direction of the first clamping part 410 relative to the second clamping part 420.

[0067] With the protruding part 430 connected to the second clamping part 420, the first clamping part 410 is provided with the through hole 440, for example, when the FPC 600 needs to be clamped, the first clamping part 410 is moved away from the second clamping part 420, so that the protruding part 430 is away from the through hole 440, the first clamping part 410 is rotated to avoid the protruding part 430 to pass through the through hole 440 on the FPC 600, that is, the first protruding part 430 is rotated to better avoid the FPC 600 placed on the second clamping part 420, after the FPC 600 is placed on the second clamping part 420, the first clamping part 410 is rotated above the protruding part 430, and the first clamping part 410 is moved towards the second clamping part 420, so that the protruding part 430 passes through the through hole 440, and the FPC 600 is clamped.

[0068] In the second aspect of the present application, the test device includes the FPC clamping device and the test device, and the test device is arranged on one side of the FPC clamping device and is used for testing the FPC 600. By loading the FPC clamping device on the test device, the FPC 600 can be tested in a clamped state, and the test precision of the test device on the FPC 600 is improved.

[0069] The above describes the embodiments of the present application in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
