Assembly tooling and assembly method for three parts of back polar plate

Abstract

The invention is applied to the technical field of production of electro-acoustic fittings, and provides an assembly tooling for three parts of a back polar plate. The assembly tooling comprises a bottom plate, a back polar plate tooling, a copper ring tooling, a plastic ring tooling and a pressure plate; and a plurality of assembly positions are arranged on various plates and located precisely. Furthermore, the invention correspondingly provides an assembly method for the three parts of the back polar plate by utilizing the assembly tooling. Therefore, due to combination and location through five simple plates, rapid and precise assembly of the three parts of the back polar plate can be realized; equipment and processes are simplified; rejects are avoided; and furthermore, due to synchronous batch operation, the efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of production of electroacoustic accessories, in particular to a three-piece assembly tool for a back plate and an assembly method. Background technique [0002] In the electret microphone, it generally includes three parts: the back plate, the plastic ring, and the copper ring. The combination of these three parts is commonly called the back plate three-piece set in the industry. At present, the assembly equipment of the three-piece back plate is complicated and the process is complicated. During the assembly process, accurate positioning is required. A little carelessness can easily cause deviation or scratches, which will affect the quality; because it is a miniature product, the assembly operation is inconvenient. A single piece or a small number of pieces are operated at the same time, which is inefficient and cannot meet the demand. [0003] In summary, there are obviously inconveniences and defects i...

Problems solved by technology

At present, the assembly equipment of the three-piece back plate is complicated and the process is complicated. During the assembly process, accurate positioning is required. A little carelessness can easily cause deviation or scratches, which will affect the quality; because it is a miniature product, the assembly operation is inconvenient. A single piece or a small number of pieces are operated at the same time, which is inefficient and cannot meet the demand

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
