[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment

[0028] As Figures 1 to 5 shown, an automatic wire welding tooling for speakers includes an upper die 1 of the tooling and a lower die 2 of the tooling. The upper die 1 of the tooling covers the lower die 2 of the tooling. A rectangular groove 21 is recessed on the lower die 2 of the tooling. A plurality of grid bars 22 are arranged at intervals on the rectangular groove 21 to divide it into a plurality of speaker accommodation cavities 23. An adsorbing speaker magnet 231 is arranged at the bottom of the speaker accommodation cavity 23. The arrangement of the adsorbing speaker magnet 231 facilitates adsorbing the speaker in the speaker accommodation cavity 23, preventing the speaker from shaking or falling off during clamping, handling, and welding, and ensuring the subsequent welding effect.

[0029] Please refer to Figures 2 - 5 , a lower electronic wire positioning groove 3 is opened on the rectangular groove 21 in front of the grid bar 22. A rectangular hole 11 corresponding to the rectangular groove 21 is opened on the upper die 1 of the tooling. An upper electronic wire positioning groove 4 corresponding to the lower electronic wire positioning groove 3 is opened on the bottom surface of the rectangular hole 11. A clearance step 5 is opened on the inner side wall of the rectangular hole 11 near the upper electronic wire positioning groove 4; the arrangement of the clearance step 5 facilitates the protection of the welding nozzle during subsequent welding and avoids knocking and damaging the welding nozzle.

[0030] In the present utility model, the upper electronic wire positioning groove 4 and the lower electronic wire positioning groove 3 are fitted to form a wire groove for fixing the electronic wire, ensuring that the welding positions are consistent, which can ensure the consistency of the solder joints and a low defect rate.

[0031] Specifically, the clearance between the wire groove formed by the fitting of the upper electronic wire positioning groove 4 and the lower electronic wire positioning groove 3 and the maximum outer diameter of the electronic wire is set to 0.00 mm - 0.02 mm, which is convenient for the operation of threading the electronic wire and ensures that the position of the wire core is in the exact middle of the speaker pad and lies flat against the pad after the electronic wire is inserted, ensuring the welding quality and welding effect.

[0032] In this embodiment, on both sides of the rectangular groove 21, a lower die magnetic body 24 and a lower die positioning hole 25 are provided on the lower die 2 of the tooling, and the lower die positioning hole 25 is located outside the lower die magnetic body 24.

[0033] Specifically, on both sides of the rectangular hole 11, an upper die magnetic body 12 and an upper die positioning post 13 corresponding to the lower die magnetic body 24 and the lower die positioning hole 25 are respectively provided on the upper die 1 of the tooling. The lower die magnetic body 24 and the upper die magnetic body 12 have opposite magnetic polarities. The upper die 1 of the tooling is covered on the lower die 2 of the tooling through the cooperation of the upper die positioning post 13 and the lower die positioning hole 25. The lower die magnetic body 24 and the upper die magnetic body 12 are made of neodymium iron boron, and their opposite magnetic polarities play a role of attracting each other with opposite sexes, preventing the phenomenon of non-tight closing after die closing.

[0034] In this embodiment, two speaker positioning posts 6 are provided at intervals on the grid bar 22. The speaker positioning posts 6 are for matching the installation requirements of the speaker size. The clearance between the speaker positioning posts 6 and the speaker mounting holes is set between 0.05 mm - 0.1 mm, and the speaker can be fixed in the speaker accommodation cavity.

[0035] In front of the rectangular groove 21, an electronic wire clearance groove 7 is recessed on the lower die 2 of the tooling. The electronic wire clearance groove 7 facilitates the threading operation. The width of the lower die 2 of this tooling can be designed according to the length of the electronic wire to ensure that the electronic wire is all within the lower die 2 of the tooling and is not clamped by the manipulator during the automated welding operation.

[0036] Specifically, on both sides of the electronic wire clearance groove 7, tooling positioning holes 8 are respectively opened on the lower die 2 of the tooling. The tooling positioning holes 8 can be set as large and small holes, effectively achieving the technical effects of positioning and preventing misalignment during die closing.

[0037] The working principle of the present utility model:

[0038] The utility model provides an automatic wire welding tooling for a loudspeaker. During specific use, the loudspeaker is placed in a loudspeaker accommodation cavity 23 and buckled on a loudspeaker positioning post 13. The upper die 1 and the lower die 2 of the tooling are closed. The electronic wire passes through a wire groove formed by the fitting of an upper electronic wire positioning groove 4 and a lower electronic wire positioning groove 3 and penetrates into the solder pads of the loudspeaker. Finally, the loudspeaker is welded by using a mechanized welding tooling.

[0039] The above description is a detailed description of a preferred and feasible embodiment of the utility model. However, the embodiment is not intended to limit the patent application scope of the utility model. Any equivalent changes or modified changes completed under the technical spirit prompted by the utility model shall fall within the patent scope covered by the utility model.
