Assembly tool for printed circuit board of automobile instrument

Abstract

The invention relates to an assembly tool for a printed circuit board of an automobile instrument. The assembly tool for the printed circuit board of the automobile instrument comprises a rectangularbase and a lamp box frame. Two elastic pressing block seats are fixedly arranged on the rectangular base, and a siding groove is horizontally formed in the top of the elastic pressing block seats. Anelastic pressing block is horizontally arranged in the sliding groove. The elastic pressing block is composed of a pressing spring and a pressing block, the head of the pressing block extends out of the sliding groove, and the other end of the pressing block is connected with the pressing spring. A semicircular arc surface is arranged at the contact position between the upper half portion of the head of the pressing block and an outer frame of the lamp box frame, and four top blocks are vertically arranged on the rectangular base. The top blocks correspond to buckles on an inner frame of the lamp box frame. A circular arc surface is arranged at the contact position of the upper ends of the top blocks and the inclined surfaces of the buckles. Installation grooves are formed in the buckles of the lamp box frame. The problem that debris is generated caused by the contact scraping between the buckles of the lamp box frame and the printed circuit board in a traditional assembly process is solved by the top blocks with the circular arc surface and the elastic pressing block structure, and the operation of manually pressing the printed circuit board in the assembly process is omitted, thelabor consumption and injury are reduced, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to the technology of installing automobile parts, in particular to an assembly tool for printed circuit boards of automobile instruments. Background technique [0002] The printed circuit board in the automobile instrument is its core component, and it is usually fixed with the light box frame in the instrument by buckle. In the existing assembly technology, the printed circuit board is generally assembled by directly pressing the printed circuit board into the light box frame of the instrument. During the assembly process, the printed circuit board is in contact with the buckle assembly guide surface on the light box frame of the instrument. Since the material of the printed circuit board is hard and the edge is sharp, while the light box frame is mostly made of PP material and the material is relatively soft, during the sliding assembly process Scratching with the printed circuit board, i...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide a printed circuit board assembly tool for automotive instrumentation. Through the design of the tooling with a round chamfer top block and a round chamfer elastic pressure block, the traditional assembly problem is solved. During the process, the buckle of the light box frame contacts and scratches the printed circuit board to generate debris, which causes the appearance defect of the car instrument
