[0047] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] like Figures 1 to 6 As shown, an embodiment of the present invention provides a clamping device for fixing an assembly part (e.g., a spring) to a product part 700 (e.g., a mobile phone) to facilitate subsequent unified screw locking operations. The clamping device includes a base plate 100, a base 200, a positioning assembly 300, a spinning assembly 400, a first rotary drive assembly 500, and a second rotary drive assembly 600, wherein:

[0049] The base 200 is set on the bottom plate 100. The base 200 has a bearing surface 201. The bearing surface 201 is used to bear the product 700. The product 700 has an assembly surface 701. The assembly parts need to be installed on this assembly surface 701. Figure 6 As shown, the assembly surfaces 701 are formed on two opposite sidewall surfaces of the product 700 .

[0050] The positioning component 300 is used to push and clamp the product part 700 to achieve precise positioning of the product part 700 and prevent the product part 700 from falling from the base 200 during rotation. The positioning component 300 has at least two postures. The positioning component 300 can clamp and fix the product part 700 in the clamping posture, so that the product part 700 is fixed on the base 200 and is not easy to be dislocated or fall off; after the product part 700 is assembled and before the product part 700 is placed on the base 200, the positioning component 300 is in a release posture. At this time, the product part 700 can be placed on the base 200 from the outside without interference, and the product part 700 can be released after the operation is completed.

[0051] The spinning assembly 400 includes a pressing block 401, referring to Figure 5 As shown, the pressing block 401 has a first surface 4013 and a second surface 4014. The pressing block 401 can move along a first preset path so that the first surface 4013 approaches or moves away from the bearing surface 201, and the pressing block 401 can move linearly along a second preset path. The extension direction of the second preset path is parallel to the extension direction of the bearing surface 201. Before the assembly part is placed on the product part 700, the pressing block 401 is at the starting end of the first preset path and the second preset path, which can avoid interference with the placement of the assembly part. After the assembly part is placed on the product part 700, The pressing block 401 first moves from the starting end to the end of the first preset path, and the first surface 4013 is close to the product part 700. When the pressing block 401 reaches the end of the first preset path, the assembly part is located on the second preset path of the pressing block 401, and the pressing block 401 begins to move linearly along the second preset path so that the second surface 4014 moves toward the side close to the assembly surface 701. When the pressing block 401 reaches the end of the second preset path, the pressing block 401 presses the assembly part against the assembly surface 701, and the second surface 4014 and the assembly surface 701 jointly clamp the assembly part.

[0052] The first rotation drive assembly 500 is connected to the base plate 100 to drive the base plate 100 to rotate around the first preset axis. In the embodiment provided in the present application, the first preset axis extends along the normal direction of the base plate 100. The first rotation drive assembly 500 can drive the base plate 100 and the product part 700 thereon to rotate along the center normal of the base plate 100.

[0053] The second rotation drive assembly 600 is connected to the first rotation drive assembly 500 to drive the first rotation drive assembly 500 to rotate around the second preset axis. The extension direction of the second preset axis is perpendicular to the extension direction of the first preset axis. The first rotation drive assembly 500 and the second rotation drive assembly 600 cooperate to form a composite motion to drive the base 200 to form a universal posture. In the embodiment provided in the present application, the second preset axis extends in the horizontal direction. By driving the first rotation drive assembly 500 to rotate, the base plate 100 and the product part 700 thereon are synchronously driven to rotate around the second preset axis.

[0054] Based on the above embodiment, the working process of the utility model is as follows:

[0055] In the initial state, the normal extension direction of the base plate 100 is parallel to the direction of gravity, so that the product part 700 can be placed. After the product part 700 is placed on the supporting surface 201 of the base 200, the positioning component 300 clamps the product part 700 and fixes it. The second rotation drive component 600 drives the base plate 100 and the product part 700 thereon to rotate along the second preset axis by a preset angle to facilitate the placement of the assembly parts. After the assembly parts on one side are implanted, the spinning component 400 fits the assembly parts on this side tightly against the corresponding On the assembly surface 701 on one side, the first rotation drive component 500 then drives the base plate 100 and the product part 700 to rotate a preset angle along the first preset axis to facilitate the placement of the assembly parts on the other side. After the assembly parts on this side are implanted, the spinning component 400 fits the assembly parts on this side tightly against the assembly surface 701 on the other side. After the assembly parts on multiple sides are fit tightly, the screw locking operation is performed to lock the assembly parts on the product part 700. This reduces the back and forth and clamping procedures and improves production efficiency.

[0056] In the embodiments provided by the present utility model, Figures 2 to 4 As shown, the positioning assembly 300 includes a first fixed block 301, a first movable block 302, a first slider 303, a second fixed block 304, a second movable block 305, a second slider 306 and a first driving member 307, wherein:

[0057] The first movable block 302 and the first fixed block 301 are arranged opposite to each other along the first direction D1. The first fixed block 301 is fixed to one end of the base 200. The first movable block 302 can approach or move away from the first fixed block 301 along the first direction D1. Initially, the positioning assembly 300 is in a released posture, and the first movable block 302 is away from the first fixed block 301 to facilitate the placement of the product part 700 on the supporting surface 201 of the base 200. Then, the first movable block 302 approaches the first fixed block 301 along the first direction D1 until the first movable block 302 and the first fixed block 301 clamp the product part 700, thereby limiting the movement of the product part 700 in the first direction D1. At this time, the positioning assembly 300 is in a clamping posture.

[0058] The second movable block 305 and the second fixed block 304 are arranged opposite to each other along the second direction D2. The second fixed block 304 is fixed to one end of the base 200. The second movable block 305 is movably arranged on the base 200 in the second direction D2. The second direction D2 intersects with the first direction D1. In the initial state, the positioning assembly 300 is in a released state. The second movable block 305 is away from the second fixed block 304 to facilitate the placement of the product 700 on the supporting surface 201 of the base 200. Then, the second movable block 305 approaches the second fixed block 304 along the second direction D2 until the second movable block 305 and the second fixed block 304 clamp the product 700, restricting the movement of the product 700 in the second direction D2. At this time, the positioning assembly 300 is in a clamping state. The product 700 is restricted from moving in both the first direction D1 and the second direction D2. The product 700 will not fall off or be misplaced during the rotation of the base plate 100.

[0059] Reference Figure 4 As shown, the first slider 303 is connected to the first movable block 302, and a first guide portion 308 is formed on the first slider 303. The second slider 306 is connected to the second movable block 305, and a first guide matching portion 309 is formed on the second slider 306. A guide matching is formed between the first guide matching portion 309 and the first guide portion 308, so that the movement between the first movable block 302 and the second movable block 305 is linked. When the first movable block 302 moves along the first direction D1, the second movable block 305 moves synchronously along the second direction D2. When the first movable block 302 approaches or moves away from the first fixed block 301, the second movable block 305 approaches or moves away from the second fixed block 304, and the product part 700 is synchronously clamped or released to achieve centering and straightening operations.

[0060] The first driving member 307 is connected to the first movable block 302 to drive the first movable block 302 to move back and forth along the first direction D1; or, the first driving member 307 is connected to the second movable block 305 to drive the second movable block 305 to move back and forth along the second direction D2. The first driving member 307 only needs to apply force to one of the first movable block 302 and the second movable block 305 to drive the first movable block 302 and the second movable block 305 to move synchronously, thereby synchronously clamping or releasing the product part 700, which is efficient and convenient, while simplifying the structure and reducing costs.

[0061] In a feasible implementation, referring to Figure 4 As shown, the first guide portion 308 includes a guide groove provided on the first slider 303, and a preset angle is formed between the extension direction of the guide groove and the first direction D1. The first guide matching portion 309 includes a guide boss protruding from the second slider 306, and the guide boss is loosely fitted in the guide groove. When the first movable block 302 and / or the second movable block 305 moves, a force is generated between the guide boss and the inner wall surface of the guide groove. Preferably, the preset angle is 45°, and the angles between the guide groove and the first direction D1 and the second direction D2 are the same, so that this force can be decomposed into a first sub-force and a second sub-force. The first sub-force extends along the first direction D1, and the second sub-force extends along the second direction D2, so that the first movable block 302 and the second movable block 305 can move synchronously.

[0062] Those skilled in the art will appreciate that the first guide portion 308 may be a guide protrusion protruding from the first slider 303 , and the first guide mating portion 309 may be a guide groove provided on the second slider 306 , which may also achieve the same technical effect and is not limited here.

[0063] In the embodiment provided by the present invention, a first slide groove and a second slide groove are formed on the side of the base 200 away from the bearing surface 201, the first slide groove extends along the first direction D1, and the second slide groove extends along the second direction D2. The first slider 303 is clearance-fitted in the first slide groove, and the second slider 306 is clearance-fitted in the second slide groove. The first driving member 307 includes a first cylinder 3071, and the piston rod of the first cylinder 3071 is connected to the first movable block 302. Under normal circumstances, the piston rod of the first cylinder 3071 extends forward. At this time, the positioning assembly 300 is in a released posture, and the first movable block 302 is in a released posture. The two movable blocks 305 are respectively away from the first fixed block 301 and the second fixed block 304. After the product part 700 is placed on the base 200, the piston rod of the first cylinder 3071 retracts, and the first movable block 302 and the second movable block 305 are respectively close to the first fixed block 301 and the second fixed block 304 to clamp the product part 700. At this time, the positioning assembly 300 is in a clamping posture. When the operation is completed and the product part 700 needs to be released, the piston rod of the first cylinder 3071 extends forward again, and the positioning assembly 300 returns to the releasing posture to facilitate the removal of the product part 700 from the base 200.

[0064] After the assembly parts are placed on the product part 700, the assembly parts are pressed against the assembly surface 701 of the product part 700 by the spinning assembly 400 to prevent the assembly parts from being misplaced or falling off, and then the assembly parts are fixed to the assembly surface 701 by means of bolt connection or the like. In a feasible embodiment, referring to Figures 1 to 3 As shown, the spinning assembly 400 further includes a slide plate 402, a rotating body 404, a first synchronous wheel 405, a synchronous belt 406, a second synchronous wheel 407 and a second driving member 408, wherein:

[0065] The slide 402 is arranged on the base plate 100 and is located at the outer circumference of the base 200. The base plate 100 may be provided with a slide rail. The slide 402 slides on the slide rail to be guided by the slide rail to move along a second preset path. The second preset path is a linear movement path. At the starting end of the second preset path, the slide 402 is close to the base 200. At the end of the second preset path, the slide 402 is away from the base 200. At least two oppositely arranged first bearing seats 403 are provided on the slide 402.

[0066] The rotating body 404 is rotatably supported on the two first bearing seats 403, and the rotational resistance of the rotating body 404 is less than the movement resistance of the slide 402. Preferably, the rotating body 404 is a circular axis structure, and the pressing block 401 has a first end and a second end. The first end of the pressing block 401 is connected to the rotating body 404, and the first surface 4013 and the second surface 4014 are formed at the second end of the pressing block 401. The first preset path is the rotational movement path of the pressing block 401 with the axis of the rotating body 404 as the center. The external force drives the rotating body 404 to rotate, which can drive the pressing block 401 to rotate synchronously. At the starting end of the first preset path, the second end of the pressing block 401 is away from the assembly part, and at the end of the second preset path, the second end of the pressing block 401 is close to the assembly part.

[0067] The first synchronous wheel 405 is fixed on the rotating body 404, and the slide plate 402 is provided with a side plate 409. The side plate 409 provides a basis for the installation of the second synchronous wheel 407. The second synchronous wheel 407 is rotatably supported on the side plate 409. The opposite ends of the synchronous belt 406 are respectively mounted on the first synchronous wheel 405 and the second synchronous wheel 407. The first synchronous wheel 405 and the second synchronous wheel 407 have the same rotation direction.

[0068] The second driving member 408 is connected to the adapter block 410 to drive the adapter block 410 to move back and forth along the second preset path. The adapter block 410 is connected to the synchronous belt 406. When the second driving member 408 drives the adapter block 410 to move, the power is transmitted to the first synchronous wheel 405 and the second synchronous wheel 407 through the synchronous belt 406, so that the first synchronous wheel 405, the second synchronous wheel 407 and the rotating body 404 rotate synchronously, thereby realizing the movement of the pressing block 401 on the first preset path.

[0069] The working process of the spinning assembly 400 is as follows:

[0070] The second driving member 408 works, and the power transmission of the adapter block 410 drives the synchronous belt 406 to move. Since the rotational resistance of the rotating body 404 is less than the movement resistance of the slide 402, the rotating body 404 will preferably rotate while the slide 402 remains stationary. The pressing block 401 fixed on the rotating body 404 moves from the initial end to the end of the first preset path, and then the rotating body 404 is restricted from rotating, and the pressing block 401 remains at the end of the first preset path. The synchronous belt 406, the first synchronous wheel 405, the second synchronous wheel 407, the bearing seat, the rotating body 404, the pressing block 401 and the slide 402 become a rigid whole. The pressing block 401 begins to move linearly on the second preset path until the pressing block 401 presses the assembly parts on the assembly surface 701 of the product part 700. At this time, the pressing block 401 is located at the end of the second preset path.

[0071] Further, refer to Figure 3As shown, in order to achieve the elastic reciprocation of the slide 402 and to adjust the movement resistance of the slide 402, the spinning assembly 400 also includes an elastic connecting member 411, which is connected to the slide 402 so that the slide 402 can elastically reciprocate along the second preset path. The elastic connecting member 411 is preferably a spring. By adjusting the elastic force of the elastic connecting member 411, the movement resistance of the slide 402 can be adjusted. In the initial state, the elastic force of the elastic connecting member 411 is greater than the rotation resistance of the rotating body 404, so the rotating body 404 will rotate first and the slide 402 remains stationary. When the rotating body 404 rotates to the end of the first preset path, it is restricted from rotating. The second driving member 408 continues to work, so that the slide 402 overcomes the elastic force of the elastic connecting member 411 and moves. After the operation is completed, the slide 402 can move back under the action of the elastic force of the elastic connecting member 411. After the slide 402 returns to the initial position, the rotating body 404 rotates in the opposite direction to drive the pressing block 401 to return to the initial position.

[0072] In order to limit the moving range of the pressing block 401 in the first preset path and make the pressing block 401 remain at the end of the first preset path and then start to move along the second preset path, refer to Figure 3 as well as Figure 5 As shown, in the embodiment provided by the present invention, the spinning assembly 400 also includes a first limit block 412, which is arranged on the slide 402; the pressing block 401 includes a first block 4011 and a second block 4012. In a feasible implementation manner, the first block 4011 and the second block 4012 are integrally formed into an "L"-shaped block structure, one end of the first block 4011 is connected to the rotating body 404, and the second block 4012 is connected to the other end of the first block 4011, and the first surface 4013 and the second surface 4014 are both formed on the second block 4012, wherein the extension direction of the first surface 4013 is parallel to the extension direction of the first block 4011, and the extension direction of the second surface 4014 is perpendicular to the extension direction of the first block 4011.

[0073] When the pressing block 401 rotates to the end of the first preset path, the first block 4011 is against the first limit block 412, the extension direction of the first surface 4013 is parallel to the extension direction of the bearing surface 201, and the extension direction of the second surface 4014 is parallel to the extension direction of the assembly surface 701. Since the first limit block 412 limits the continued movement of the pressing block 401, the rotating body 404 cannot continue to rotate. The synchronous belt 406, the first synchronous wheel 405, the second synchronous wheel 407, the bearing seat, the rotating body 404, the pressing block 401 and the slide plate 402 become a rigid whole. In this way, the second driving member 408 continues to apply force. After the slide plate 402 overcomes the elastic force of the elastic connecting member 411, the slide plate 402 can move along the second preset path until the pressing block 401 presses the assembly parts against the assembly surface 701 of the product part 700. At this time, the slide plate 402 moves to the end of the second preset path.

[0074] In order to limit the moving range of the pressing block 401 in the second preset path and enable the slide 402 to remain at the starting end of the second preset path in the initial state, in the embodiment provided by the present invention, reference is made to Figure 3 As shown, the spinning assembly 400 also includes a second limit block 413, which is arranged on the base plate 100. In the initial state, the slide 402 is against the second limit block 413. After the operation is completed, the slide 402 can move back under the elastic force of the elastic connecting member 411. After the slide 402 returns to the position against the second limit block 413, the second limit block 413 limits the movement of the slide 402. At this time, the rotating body 404 rotates in the opposite direction to drive the pressing block 401 to rotate in the opposite direction.

[0075] In a feasible implementation, referring to Figure 1 as well as Figure 2 As shown, the second driving member 408 includes a second cylinder 4081, the cylinder body of the second cylinder 4081 is fixed on the base plate 100, the piston rod of the second cylinder 4081 is connected to the adapter block 410, and the extension direction of the piston rod of the second cylinder 4081 is parallel to the extension direction of the first preset path.

[0076] In the initial state, the piston rod of the second cylinder 4081 is in a retracted state. When the spinning assembly 400 is operating, the piston rod of the second cylinder 4081 extends forward, and the power is transmitted through the adapter block 410 to push the synchronous belt 406 to move. Because the rotation resistance of the rotating body 404 is less than the movement resistance of the slide 402, the rotating body 404 will preferably rotate while the slide 402 remains stationary, and the pressing block 401 thereon moves from the initial end to the end of the first preset path, and the first block 4011 is against the first limit block 412. When the rotating body 404 is restricted from rotating, the synchronous belt 406, the first synchronous wheel 405, the second synchronous wheel 407, the bearing seat, the rotating body 404, the pressing block 401 and the slide 402 become a rigid whole, and the piston rod of the second cylinder 4081 continues to extend forward. After the slide 402 overcomes the elastic force of the elastic connecting part 411, the slide 402 can move along the second preset path until the pressing block 401 presses the assembly part against the assembly surface 701 of the product part 700. At this time, the slide 402 moves to the end of the second preset path.

[0077] After the operation is completed, the elastic force of the elastic connecting member 411 is released, and the piston rod of the second cylinder 4081 naturally retracts. The slide plate 402 can move back under the elastic force of the elastic connecting member 411. After the slide plate 402 returns to the initial position, the rotating body 404 rotates in the opposite direction to drive the pressing block 401 to return to the initial position.

[0078] In the embodiments provided by the present utility model, Figure 1 As shown, the first rotation drive assembly 500 includes a first motor 501, the output shaft of the first motor 501 is connected to the base plate 100, the first preset axis is the axis of the output shaft of the first motor 501, and the extension direction of the output shaft of the first motor 501 is parallel to the normal direction of the base plate 100. Preferably, the center normal of the base plate 100 coincides with the axis of the output shaft of the first motor 501. When the first motor 501 works, it drives the base plate 100 and the base 200 installed on the base plate 100 and the product part 700 fixed on the base 200 to rotate synchronously. The angle of rotation can be determined according to actual needs and is not limited here.

[0079] In a feasible implementation mode, continue to refer to Figure 1As shown, the second rotation drive assembly 600 includes a second motor 601, a second bearing seat 602, a swing arm 603 and a flip plate 604. There are two second bearing seats 602 and two swing arms 603. The two second bearing seats 602 are relatively arranged on the same horizontal plane. Each swing arm 603 corresponds to a second bearing seat 602. Each swing arm 603 has a first end and a second end. The first end of the swing arm 603 is rotatably connected to the second bearing seat 602. The opposite ends of the flip plate 604 are respectively connected to the second ends of the two swing arms 603. The output shaft of the second motor 601 is transmission-connected to at least one swing arm 603. The first motor 501 and the base 200 are both arranged on the flip plate 604.

[0080] The second motor 601 works, driving the swing arm 603 to swing around the second preset axis, and then drives the first motor 501, the base plate 100, the base 200 and the product part 700 thereon to swing together. The swing angle can be determined according to actual needs and is not limited here.

The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings.
