[0028] 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.

[0029] like Figures 1 to 4 , combined Figure 6As shown, a magnet assembly combined tooling structure is used for assembling a magnet assembly 100 for wireless charging of mobile phones. The magnet assembly 100 includes an iron sheet 101 and a magnet 102. The iron sheet 101 includes a first iron sheet 1011 in a ring structure and a second iron sheet 1012 in a sheet structure. The magnet 102 includes thirty-six first magnets 1021 that are spaced apart and form a ring structure, and two second magnets 1022 that are arranged side by side and located outside the ring structure. The first iron sheet 1011 and the first magnet 1021, as well as the second iron sheet 1012 and the second magnet 1022 need to be positioned and assembled to form the magnet assembly 100. After the magnet assembly 100 is assembled, it needs to be attached with Mylar 103 in the subsequent process to facilitate the protection, storage, transportation and attachment of the magnet assembly 100. In response to the above requirements, the magnet assembly assembly tooling structure includes a first tooling plate 1, a second tooling plate 2 and an auxiliary tooling plate 3, all of which are made of hard plastic. The upper end surface of the first tooling plate 1 is provided with a first bottom positioning groove 111 in an annular structure and a second bottom positioning groove 112 in a sheet structure for positioning the first iron sheet 1011 and the second iron sheet 1012 respectively. The upper end surface of the second tooling plate 2 is provided with thirty-six first middle positioning grooves 211 arranged at intervals and forming an annular structure to form a first positioning area 2a for Thirty-six first magnets 1021 are positioned, and a second middle positioning groove 212 with a sheet-like structure is provided on the upper end surface to form a second positioning area 2b for positioning two second magnets 1022. The upper end surface of the auxiliary tooling plate 3 is provided with a first top positioning groove 311 with an annular structure and a second top positioning groove 312 with a sheet-like structure. The first top positioning groove 311 and the second top positioning groove 312 are respectively fixed with a first magnetic attraction member 3a with an annular structure and a second magnetic attraction member 3b with a sheet-like structure. The first magnetic attraction member 3a and the second magnetic attraction member 3b with an annular structure are respectively fixed. The two magnetic members 3b can be made of stainless steel. When the auxiliary tooling plate 3 is abutted and positioned at the lower end of the second tooling plate 2, the first magnetic member 3a and the second magnetic member 3b can respectively have an adsorption effect with the first magnet 1021 and the second magnet 1022, thereby fixing the first magnet 1021 and the second magnet 1022 on the second tooling plate 2. After the auxiliary tooling plate 3 and the second tooling plate 2 are inverted, the first magnet 1021 and the second magnet 1022 are still fixed on the second tooling plate 2. The inverted second tooling plate 2 is abutted. On the first tooling plate 1, the first magnet 1021 and the second magnet 1022 are respectively in contact with and bonded to the first iron sheet 1011 and the second iron sheet 1012 coated with glue on the upper end surface, thereby forming a magnet assembly 100; by removing the auxiliary tooling plate 3 first and then the second tooling plate 2, the magnet assembly 100 positioned on the first tooling plate 1 can be exposed, and the magnet part 102 is located at the upper end, which facilitates the attachment of the Mylar 103 to the end surface of the magnet part 102 away from the iron sheet part 101 in the subsequent process.

[0030] In the present invention, the iron sheet is positioned on the first tooling plate 1, the magnet is positioned on the second positioning plate 2, and the magnet is adsorbed and fixed by a magnetic attraction piece fixed on the auxiliary tooling plate 3 to ensure a stable position. After the second tooling plate 2 and the auxiliary tooling plate 3 are inverted, the magnet is positioned on the iron sheet (bonded to each other), completing the assembly of the magnet and the iron sheet to form a magnet assembly. On the one hand, the stability and accuracy of the magnet can be effectively guaranteed during assembly, thereby improving the assembly quality of the magnet assembly 100. On the other hand, the structure is simpler and easier to operate. Furthermore, a multi-station form can be set, which is more suitable for the assembly of multiple components and multiple products, thereby improving assembly efficiency.

[0031] In order to ensure that the iron sheet and the magnet, as well as the magnet and the magnetic attraction member can interact with each other in precise alignment, a plug-in positioning structure is provided between the first tooling plate 1 and the second tooling plate 2, as well as between the second tooling plate 2 and the auxiliary tooling plate 3. More specifically, the plug-in positioning structure includes mutually cooperating positioning columns and positioning holes. For example, the first tooling plate 1 is provided with a plurality of first positioning columns 121 and a plurality of first positioning holes 122, the second tooling plate 2 is provided with a plurality of second positioning columns 221 and a plurality of second positioning holes 222, and the auxiliary tooling plate 3 is provided with a plurality of second positioning columns 221 and a plurality of second positioning holes 222. A pair of third positioning posts 32 are provided at the line position. When assembling the magnet assembly, the second tooling plate 2 and the auxiliary tooling plate 3 are sleeved on the third positioning posts 32 through the second positioning holes 222 to realize the positioning of the two. After the two are positioned and inverted, the first positioning posts 121 are extended into the second positioning holes 222 (the first positioning posts located at a pair of corners do not abut or interfere with the third positioning posts in the same second positioning hole), and the first positioning holes 122 are sleeved on the second positioning posts 221 to realize the positioning of the first tooling plate 1 and the second tooling plate 2.

[0032] Furthermore, the upper end surfaces of the plurality of positioning posts are formed with guide cut surfaces, which facilitate their insertion into the positioning holes.

[0033] In addition, a pair of limit blocks 33 are provided at the diagonal positions on the auxiliary tooling plate 3 , which can be used to position the corners of the second tooling plate 2 .

[0034] Preferably, the height of the magnetic parts such as the second magnetic part 312 protrudes from the auxiliary tooling plate 3, and the lower end surface of the second tooling plate 2 is provided with a clearance groove 20, and the second magnetic part 312 is embedded in the clearance groove 20. On the one hand, the second magnetic part 312 and the second magnet 1022 can be more accurately aligned, and on the other hand, the closer distance between the two can ensure the magnetic attraction; the first magnetic part 311 can also be set to a similar structure as mentioned above.

[0035] like Figure 5As shown, in another embodiment of the present invention, the magnet assembly combined tooling structure also includes a pressing tooling 4, which includes a mounting plate 41 and a push rod arranged at the lower end of the mounting plate 41, the push rod including thirty-six first push rods 421 that are spaced apart and form a ring structure, and a pair of second push rods 422 arranged outside the ring structure, and a through hole 210 is provided in the middle positioning groove on the second tooling plate 2, which passes through its body. The push rod extends into the through hole 210 from the side of the through hole away from the middle positioning groove and abuts on the magnet. After removing the auxiliary tooling plate 3 and before removing the second tooling plate 2, the mounting plate 41 is used to drive the push rod to extend into the through hole 210 and abut on the magnet, and the magnet is pressed against the iron sheet (coated with glue). The downward pressure-maintaining action can ensure that the magnet is firmly connected to the iron sheet.

[0036] The above-mentioned use of the top pressing tooling 4 can be in the form of mechanical drive, such as installing the connecting part 43 of the top pressing tooling on the output end of the external pressing mechanism, and realizing downward pressure and pressure maintenance through the external pressing mechanism; it can also be in the form of manual operation, such as the operator holding the connecting part 43 for operation, and it is necessary to set a directional mark on the mounting plate 41 to ensure that the top rod can be accurately and matchingly extended into the through hole 210 on the second tooling plate 2.

[0037] 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.
