Specific implementation

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1-5 A jig structure for processing computer tablet back cover, including drive box 1, the top of drive box 1 is connected with placing table 5, the bottom of placing table 5 is provided with clamping assembly 2, clamping assembly 2 includes rotating groove 23, two-way threaded rod 22 is rotatably installed in rotating groove 23, one end of two-way threaded rod 22 is connected with motor 21, the top of rotating groove 23 is provided with symmetrical moving groove 231, clamping piece 24 is slidably installed in moving groove 231, clamping piece 24 is screw-connected with two-way threaded rod 22, the top of clamping piece 24 is arranged above placing table 5, buffer pad 241 is installed on the top of clamping piece 24.

[0026] Specifically, when different sizes of back covers need to be clamped, the motor 21 is started. The output shaft of the motor 21 is connected to one end of the bidirectional threaded rod 22, and the motor 21 rotates to drive the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22 is located in the rotating groove 23, and the screw directions of the two ends thereof are opposite. The clamping pieces 24 pass through the moving grooves 231 and are matched with the moving grooves 231, and the clamping pieces 24 are screw-connected with the bidirectional threaded rod 22. According to the screw transmission principle, when the bidirectional threaded rod 22 rotates, the two clamping pieces 24 will move in opposite directions under the guidance of the moving grooves 231, so as to adjust the distance between the two clamping pieces 24. Since the top of the clamping piece 24 is arranged above the placement table 5, when placing the back cover, the back cover is placed on the placement table 5, and then the top of the clamping piece 24 is adjusted to clamp the back cover, and the buffer pad 241 of the top of the clamping piece 24 can be in contact with the back cover to prevent damage to the back cover.

[0027] The back cover can be precisely positioned by the clamping assembly 2. The clamping assembly 2 is symmetrical, and the two clamping pieces 24 can move synchronously and symmetrically by the driving of the bidirectional threaded rod 22, so that the back cover can be clamped in the middle position of the placement table 5 when the distance between the clamping pieces 24 is adjusted.

[0028] Embodiment 2:

[0029] To achieve preliminary positioning of the back cover, please refer to Figures 1-5 On the basis of embodiment 1, the placement table 5 is provided with the symmetrically arranged fixing assembly 3, and the fixing assembly 3 is perpendicular to the clamping assembly 2.

[0030] The fixing assembly 3 comprises a sliding groove 31, a sliding rod 32 is fixedly installed in the sliding groove 31, a fixed block 34 is slidingly installed on the sliding rod 32, the bottom of the fixed block 34 is matched with the sliding groove 31, and one side of the fixed block 34 is connected with the inner wall of the sliding groove 31 through the spring 33.

[0031] Specifically, in the initial state, the spring 33 is in a natural state, and the fixed block 34 is located at a certain position in the sliding groove 31 under the action of the spring 33. When the back cover is placed on the placement table 5, the edge of the back cover will contact the fixed block 34. Due to the presence of the back cover, the fixed block 34 will be subjected to pressure exerted by the edge of the back cover. This pressure makes the fixed block 34 slide along the sliding rod 32 in the sliding groove 31, while compressing the spring 33. The bottom of the fixed block 34 is adapted to the sliding groove 31, ensuring the stability and directionality of the fixed block 34 during sliding. The spring 33 will generate a counterforce during compression, which is exerted on the edge of the back cover through the fixed block 34. Thus, when the two symmetrically arranged fixed assemblies 3 fix the back cover from the direction perpendicular to the clamping assembly 2, regardless of the size variation of the back cover in this direction, the fixed block 34 can adapt to and clamp the back cover through the expansion and contraction of the spring 33, thereby achieving preliminary positioning of the back cover, facilitating further positioning by the clamping assembly 2.

[0032] Embodiment 3:

[0033] To achieve convenient removal of the back cover, please refer to Figures 1-5 On the basis of Embodiment 1 and Embodiment 2, a guide rod 11 is fixedly installed inside the drive box 1, and the top of the guide rod 11 is fixedly connected with the rotating groove 23.

[0034] The lifting assembly 4 is installed on the guide rod 11, and the lifting assembly 4 includes a moving plate 42. The two ends of the moving plate 42 are slidably installed on the guide rod 11 through the through holes 45.

[0035] The bottom middle of the moving plate 42 is connected with the output end of the electric telescopic rod 41, and the electric telescopic rod 41 is installed at the bottom of the inner cavity of the drive box 1. The top side of the moving plate 42 is fixedly installed with a supporting rod 43, and the top of the supporting rod 43 is fixedly connected with a supporting plate 44. The supporting plate 44 slidably penetrates the placement table 5.

[0036] Specifically, if the back cover is a common flat back cover that is not specially designed with a dedicated force application point, it may be difficult for the operator to find a suitable force application point when removing it. In addition, the surface of the back cover is usually smooth and flat, and the friction between the fingers and the back cover is limited when directly lifting it with the hands. Moreover, if the force is not properly applied, the back cover may easily slip or deform due to uneven force.

[0037] Therefore, when the back cover needs to be taken out, the electric telescopic rod 41 is started. The output end of the electric telescopic rod 41 extends upward, pushing the moving plate 42 to move upward along the guide rod 11. Because the two ends of the moving plate 42 are adapted to slide through the through hole 45 and the guide rod 11, the guide rod 11 provides stable vertical guidance for the moving plate 42, ensuring that the moving plate 42 can rise smoothly. As the moving plate 42 rises, the support rod 43 fixed on the top side of the moving plate 42 also rises, in turn driving the support plate 44 at the top to slide upward. Since the support plate 44 is slid through the placement table 5, when the support plate 44 rises to a certain height, it will lift the back cover placed on the placement table 5, making it leave the placement table 5 and the fixing range of the clamping assembly 2 and the fixing assembly 3. At this time, since the back cover has left the placement table 5, the operator can more easily put his fingers into the bottom of the back cover to hold it from below or pinch the edge of the back cover. The force exerted by the fingers will not be hindered by the placement table 5, and can more directly act on the back cover, thereby facilitating the operator to take out the back cover.

[0038] Working principle: When the device is in use, if its size is unknown or does not match the current distance between the clamping members 24, the motor 21 is started. The motor 21 drives the bidirectional threaded rod 22 to rotate. Because the threads at both ends of the bidirectional threaded rod 22 are opposite and the clamping members 24 are screw-connected with it and guided by the moving grooves 231, the two clamping members 24 will move synchronously in opposite directions, so that the clamping members 24 move to the two ends of the rotating grooves 23, respectively, to facilitate subsequent clamping. The back cover is placed on the placement table 5, the edge of the back cover contacts the fixing block 34 in the fixing assembly 3, generating pressure on the fixing block 34, causing it to slide in the sliding groove 31 along the sliding rod 32 and compress the spring 33. The counterforce generated by the compression of the spring 33 acts on the edge of the back cover through the fixing block 34, and the two symmetrical fixing assemblies 3 fix the back cover from the direction perpendicular to the clamping assembly 2. Regardless of the size of the back cover in this direction, the fixing block 34 can adapt to it through the expansion of the spring 33 and clamp the back cover on the axis of the moving grooves 231, completing the preliminary positioning of the back cover;

[0039] The motor 21 is started again to drive the bidirectional threaded rod 22 to rotate, moving the clamping members 24 along the moving grooves 231 and clamping the back cover fixed by the fixing assembly 3. The characteristics of the bidirectional threaded rod 22 can further adjust the position of the back cover, so that back covers of different sizes can be fixed in the middle part of the placement table 5. The buffer pad 241 can prevent the back cover from being damaged;

[0040] When the back cover is finished and needs to be taken out, the electric telescopic rod 41 is started. The output end of the electric telescopic rod 41 extends upward, pushes the moving plate 42 to move upward along the guide rod 11, and as the moving plate 42 rises, the support rod 43 on the top side of the moving plate 42 drives the support plate 44 to slide upward. When the support plate 44 rises to a certain height, the back cover is lifted from the placement table 5 and the fixed range of the clamping assembly 2 and the fixing assembly 3. At this time, the operator can easily and conveniently take out the back cover.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
