Problems solved by technology

[0002] At present, there are LED lights on the PCB of smart bracelets on the market. In order to achieve the smallest light shadow seen outside the product and consistent lighting, it is necessary to add assembly parts on the PCB; currently, the assembly parts on the PCB are marked on the PCB. , Assemble the assembly along the marking line, plus manual assembly, this method is easy to be misaligned, the assembly effect is difficult to guarantee, and the defect rate is high; therefore, a tool with fixed positioning is needed to ensure the yield rate of the product

Abstract

The invention provides a fixing fixture, which comprises a base for fixing a PCB and an upper cover for limiting movement of an assembly unit, wherein the base is provided with at least two positioning columns; the PCB is provided with first positioning holes with positions corresponding to the positioning columns; the upper cover comprises second positioning holes corresponding to the positioningcolumns and a processing through groove for limiting movement of the assembly unit; and the opposite side walls between the processing through groove and the assembly unit are provided with positioning surfaces contacted with the assembly unit. In comparison with the prior art, through the match between the positioning columns on the fixture base and the positioning holes on the upper cover of the fixture, the positioning accuracy is improved; and when the assembly unit is assembled, the assembly area on the PCB is determined through the positioning surface of the upper cover, non offset in the case of assembly of the assembly unit is thus ensured, and the production yield is improved.

Description

technical field [0001] The invention belongs to the field of structural design, and in particular relates to a fixing jig. Background technique [0002] At present, there are LED lights on the PCB of smart bracelets on the market. In order to achieve the smallest light shadow seen outside the product and consistent lighting, it is necessary to add assembly parts on the PCB; currently, the assembly parts on the PCB are marked on the PCB. , Assembling the assembly along the marking line, plus manual assembly, this method is easy to be misaligned, the assembly effect is difficult to guarantee, and the defect rate is high; therefore, a tool with fixed positioning is needed to ensure the product yield. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a positioning jig, so that the positioning of the PCB board when assembling the silicone is more accurate and the deviation is guaranteed. [0004] ...
