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

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0029] see figure 1 , the present invention provides a three-piece assembly tooling for the back plate. The three-piece back plate assembly tooling includes a bottom plate 1 , a back plate tooling 2 , a copper ring tooling 3 , a plastic ring tooling 4 and a pressure plate 5 .
[0030] The bottom plate 1 is a light plate structure; the back plate tooling 2 is a plate structure with a number of blind holes 21 evenly arranged on one side, the depth of the blind holes 21 is equal to the height of the back plate 6, and the diameter of the blind holes 21 is not smaller than the back electrode The outer...

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...
