Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to an assembly jig for a latch assembly. Background Art

[0002] A latch assembly includes a latch made of 316L material and a housing made of 304 material. The latch is MIM-molded, sandblasted, and treated with PVD. The housing is stamped and then painted. During assembly, the latch and housing are bonded together using adhesive. Conventional assembly methods often involve manual assembly and press-fitting of the latch and housing. Workers must first remove the release paper from one side of the adhesive and then attach it to the latch. The worker then removes the release paper from the other side and presses the housing onto the latch. Manual assembly is inefficient, has poor precision, and is difficult to guarantee product quality. Therefore, the present invention provides a latch assembly jig. Utility Model Content

[0003] The main purpose of the present utility model is to provide a latch assembly assembly jig, wherein the lower template and the positioning plate are used to position the latch and the housing, thereby ensuring the pressing accuracy of the latch and the housing; the latch positioning piece and the positioning hole are both provided in plurality, which can be mass-produced, greatly improving production efficiency.

[0004] The utility model achieves the above-mentioned purpose through the following technical solution: a latch assembly jig, comprising a lower template, an upper template, and a limit plate and a positioning plate arranged between the lower template and the upper template from bottom to top, positioning columns are provided on both sides of the lower template, positioning holes are provided on the limit plate, the positioning plate and the upper template, a plurality of latch positioning pieces are provided on the upper end surface of the lower template, and a plurality of shell positioning holes corresponding to the latch positioning pieces are provided on the positioning plate.

[0005] Preferably, a layer of cloth is provided between the lower template and the limiting plate.

[0006] Preferably, the pad is flocked cloth.

[0007] Preferably, the upper template and the lower template are both made of bakelite.

[0008] Preferably, the limiting plate is made of stainless steel.

[0009] The beneficial effects of the technical solution of the present utility model are as follows: the lower template and the positioning plate are used to position the latch and the shell, thereby ensuring the pressing accuracy of the latch and the shell; a plurality of latch positioning pieces and positioning holes are provided, which can be mass-produced, greatly improving production efficiency; the limiting plate is supported by stainless steel material, and is used to limit the pressing depth of the upper template to prevent the product from being crushed.

[0015] The present invention will be further described in detail below with reference to specific embodiments.

[0016] Example:

[0017] like Figures 1 to 3 As shown, the utility model is a latch 8 assembly jig, comprising a lower template 1, an upper template 2, and a limit plate 3 and a positioning plate 4 arranged between the lower template 1 and the upper template 2 from bottom to top, a positioning column 5 is provided on both sides of the lower template 1, and positioning holes are provided on the limit plate 3, the positioning plate 4 and the upper template 2. A plurality of latch positioning pieces 6 are provided on the upper end surface of the lower template 1, and a plurality of shell positioning holes corresponding to the latch positioning pieces 6 are provided on the positioning plate 4.

[0018] A layer of padding cloth 7 is provided between the lower template 1 and the limiting plate 3 .

[0019] The padding cloth 7 is flocked cloth, which increases the buffer between the latch 8 and the lower template 1 to avoid crushing.

[0020] The upper template 2 and the lower template 1 are both made of bakelite.

[0021] The limiting plate 3 is made of stainless steel and can limit the pressing depth of the upper template 2 to prevent the product from being crushed.

[0022] The working process of the present utility model is as follows: provide a latch 8, a shell 9 and a backing glue, the lower end surface of the latch 8 is provided with a positioning groove, the backing glue includes two layers of release paper and a ring-shaped adhesive sticker located between the two release papers, remove the upper template 2 and the positioning plate 4, place multiple latches 8 on the lower template 1, insert the latch positioning piece 6 into the positioning groove, peel off the release paper on one side of the backing glue, and place it on multiple latches 8, position it through the positioning column 5, the limit plate 3 and the positioning holes preset on the backing glue, install the upper template 2 on the lower template 1 and press down so that the backing glue sticks tightly to the latch 8, remove the upper template 2, peel off the release paper on the upper surface of the backing glue, install the positioning plate 4, place the shell 9 into the shell positioning hole, and finally cover the upper template 2 and press down so that the shell 9 and the latch 8 are pressed together.

[0023] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
