[0002] In smart watch electronic parts, it is necessary to assemble and form Figure 5 The magnet assembly 100 with a curved surface structure shown in the figure has a second magnet unit 100b with a curved surface structure symmetrically bonded to both sides of a first magnet unit 100a with a curved surface structure. Therefore, the contact surfaces of the second magnet unit 100b and the first magnet unit 100a need to be precisely docked through an arc-shaped moving trajectory.

[0003] In the prior art, for example, a jig for assembling a plurality of magnet monomers into a long strip magnet with application number 202321215012.7 can be used for a structure in which the side surfaces of the magnets after assembly are flat. However, the structure does not have an arc surface and is not suitable for positioning the above-mentioned products or guiding the movement of the magnet monomers. Moreover, when the first magnet monomer 100a and the second magnet monomer 100b are brought into close contact with each other, it is necessary to avoid misalignment due to the repulsive force between them, which may result in inaccurate docking. Utility Model Content

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 5 As shown, an assembly jig for a magnet assembly with a curved surface structure is used to assemble a magnet assembly 100 with a curved surface structure. The magnet assembly 100 is formed by gluing a first magnet monomer 10a with a curved surface structure located in the middle position and a pair of symmetrical second magnet monomers 10b with a curved surface structure located on opposite sides of the first magnet monomer 10a. The assembly jig includes a positioning base plate 10 and a side pressure plate 20. The positioning base plate 10 is made of a magnetic material, such as stainless iron, and can be adsorbed with the magnet assembly 100 (magnet monomer). At least one placement groove 101 is provided on the positioning base plate 10. The placement groove 101 forms an opening 1010 on one side of the positioning base plate, and forms a curved side wall 102 on the other side for positioning multiple magnet monomers with a curved surface structure. The side pressure plate 20 is an L-shaped structure. A push block 21 is provided at the end of the side pressure plate 20 and between the horizontal plate 201 and the vertical plate 202. When the horizontal plate 201 abuts against the upper end surface of the positioning base plate 10 and moves laterally, the multiple magnet monomers are located between the vertical plate 202 and the curved side wall 102 and abut against each other after being pushed by the push block 21.

[0027] In the present invention, first, the first magnet monomer 10a and the second magnet monomer 10b are placed in the placement groove 101 at intervals according to the orientation of the assembled magnet assembly 100, and the sides of the three magnet monomers with the arc surface structure are all in contact with the arc surface side wall 102, and the other side wall of one of the second magnet monomers 10b is preferably in contact with the side wall adjacent to the arc surface side wall 102 in the placement groove 101, and then glue is evenly applied on the adjacent side walls of the first magnet monomer 10a and the second magnet monomer 10b at intervals. Due to the magnetic attraction characteristics of the positioning base plate 10, the first magnet monomer 10a and the second magnet monomer 10b are placed in the placement groove 101. , and can maintain a stable position during the process of applying glue; after the glue is applied, the lower end of the horizontal plate 201 on the side pressure plate 20 is abutted against the positioning base plate 10, and the push block 21 is abutted against another second magnet monomer 10b. The side pressure plate 20 is operated to translate a certain distance to abut the first magnet monomer 10a and the second magnet monomer 10b, thereby realizing the bonding of glue and forming the magnet assembly 100. In this process, multiple magnet monomers are located between the vertical plate 202 and the curved side wall 102, which can avoid the magnet monomer from overcoming the magnetic attraction between it and the positioning base plate 10 due to the external thrust during the movement, resulting in dislocation, and can ensure the precise docking of the magnets.

[0028] Preferably, a contoured arc surface 22 is provided on the side wall of the vertical plate 202, which matches the arc surface structure of the magnet assembly 100 and can better limit the movement of the magnet unit in the lateral direction.

[0029] On the basis of avoiding lateral dislocation of the magnet monomer during translation, further, the lower end surface of the vertical plate 202 forms a downward pressure surface 220 that abuts against at least part of the end surface of the magnet monomer, that is, the downward pressure surface 220 can press down at least the outer end surface of the first magnet monomer 10a and the second magnet monomer 10b, thereby avoiding vertical dislocation of the magnet monomer during translation.

[0030] In addition, a guide post 23 can be set at the lower end of the horizontal plate 201, and an arc-shaped slide groove 103 can be set at the upper end of the positioning base plate 10. The guide post 23 can be slidably set in the arc-shaped slide groove 103. Since multiple magnet monomers are placed in the placement groove 101 in an arc shape, the movement path of the magnet monomers during the abutment process is also arc-shaped. Therefore, through the cooperation of the guide post 23 and the arc-shaped slide groove 103, the movement path of the side pressure plate 20 (i.e., the push block 21) can be realized as an arc along the arc side wall 102. At the same time, with the help of the contoured arc surface 22 on the vertical plate 202, the precise arc movement of multiple magnet monomers can be achieved on the basis of limiting the magnet monomers to ensure precise docking.

[0031] Furthermore, two parallel guide posts 23 and arc-shaped slots 103 are provided to prevent the side pressure plate 20 from deflecting during movement, and to ensure that the contoured arc surface 22 and the arc-shaped side wall 102 are always in contact with the opposite side walls of the magnet unit.

[0032] In one embodiment of the present invention, in order to facilitate the application of external thrust to the side pressure plate 20 , a translation push rod 24 is provided at the upper end of the horizontal plate 201 , which can be easily grasped and pushed.

[0033] Combine Figure 3 and Figure 4 In another embodiment of the present invention, the upper end of the side pressure plate 20 is provided with side push rods 25 equal to the number of magnet monomers, that is, three in the present invention. The three side push rods 25 form an arc structure similar to the arc side wall 102 and in the opposite direction. The positioning base plate 10 is provided with connecting grooves 104 connected to the placement groove 101 and equal to the number of the side push rods 25. The three side push rods 25 are respectively embedded in the connecting grooves 104 to push each magnet monomer away from the side wall of the placement groove 101. Specifically, after the three magnet units are bonded together with glue to form the magnet assembly 100, since the magnet assembly 100 is adsorbed on the positioning base plate 10 and the structure of the magnet assembly 100 is relatively small, in order to facilitate the removal of the magnet assembly 100 from the placement slot 101 (it is necessary to achieve synchronous movement of the three magnet units, that is, to avoid unstable adhesion between each other caused by successive movement), the side pressure plate 20 is inverted so that the three side push rods 25 are respectively embedded in the three connecting slots 104. The magnet assembly 100 can be conveniently removed from the placement slot 101 from the opening 1010 by holding the vertical plate 202 and moving it horizontally. It should be noted that: under the premise of having the side push rod 25, it can also be used as a translation push rod 24, that is, there is no need to set up a separate translation push rod 24.

[0034] In the present invention, the number of placement slots 101 is preferably set to four, and the four magnet assemblies 100 are formed by operating the side pressure plate 20 to translate at each placement slot 101. This design can also increase the volume of the positioning base plate 10, making it easier for manual handheld operation.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
