Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production jigs for voice coil and diaphragm assemblies, and particularly refers to an auxiliary wire aligning jig for voice coil and diaphragm assemblies. Background Art
[0002] A voice coil is a coil through which an electric current passes in a loudspeaker and is an important part of the mechanical wave system of an electro-dynamic loudspeaker. It can also be said to be the heart of the loudspeaker. As shown in the Figure 3 accompanying drawing, a voice coil and diaphragm assembly 5 on the market is composed of a skeleton 50, a coil 51 wound on the surface of the skeleton 50, cotton threads 52 welded to two lead-out ends of the coil 51, and a diaphragm 53 bonded to the top end of the skeleton 50. A wire outlet groove 530 is formed in the diaphragm 53, and two cotton threads 52 need to be led out from the top of the diaphragm 53 through the wire outlet groove 530. Since the customer has specific requirements for the lengths and arc shapes of the two cotton threads 52, the shapes of the cotton threads 52 need to be trimmed after the cotton threads 52 pass through the wire outlet groove 530. Currently, employees use cotton swabs to straighten the arcs of the leads. This method is difficult to operate, the arc shapes of the cotton threads are not accurately fixed, and repeated adjustments are required, resulting in long working hours, low production efficiency, and increased production costs. Summary of the Invention
[0003] The problem to be solved by the utility model is to provide an auxiliary wire aligning jig for voice coil and diaphragm assemblies, which reduces the difficulty of wire alignment and improves the wire alignment efficiency.
[0004] To solve the above technical problems, an auxiliary wire aligning jig for voice coil and diaphragm assemblies provided by the utility model includes a cylinder. A window is formed in the side wall at the top end of the cylinder, and a crescent-shaped shaping plate is arranged at the bottom of the window. Cotton thread outlets are formed between the two ends of the shaping plate and the side walls of the window.
[0005] Preferably, the top surface of the shaping plate is in the same plane as the top surface of the cylinder.
[0006] Preferably, avoidance inclined surfaces are arranged on both side walls of the window.
[0007] The beneficial effects of the utility model are as follows: The utility model provides an auxiliary wire aligning jig for voice coil and diaphragm assemblies. When threading and trimming the cotton threads, first place the diaphragm of the voice coil and diaphragm assembly on the top of the cylinder, and place the skeleton inside the cylinder. At this time, the two cotton threads should be pulled out from the two cotton thread outlets respectively. The ends of the two cotton threads are passed through the wire outlet groove from the top of the diaphragm and straightened in a crossed shape. The cotton threads will be placed on the outer side wall of the shaping plate, thereby playing a role in shaping the arcs and shapes of the cotton threads. After trimming is completed, the voice coil and diaphragm assembly can be taken out from the wire aligning jig. It has a simple structure and is easy to use, can play an auxiliary role, greatly reduces the difficulty of wire alignment, reduces working hours, improves production efficiency, and reduces production costs.

Detailed implementation manners
[0013] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure.
[0014] Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.
[0015] Reference Figures 1 - 4 .
[0016] The present utility model provides an auxiliary whole-line fixture for a voice coil and diaphragm assembly, which includes a cylinder 1. A window 2 is provided on the top side wall of the cylinder 1. A crescent-shaped shaping plate 3 is arranged at the bottom of the window 2. Cotton thread lead-out ports 4 are formed between the two ends of the shaping plate 3 and the side walls of the window 2 respectively.
[0017] The specific working principle is as follows: When threading and trimming the cotton thread, first place the diaphragm 53 of the voice coil and diaphragm assembly 5 on the top of the cylinder 1, and place the skeleton 50 inside the cylinder 1. At this time, the two cotton threads 52 should be pulled out from the two cotton thread lead-out ports 4 respectively. The ends of the two cotton threads 52 are passed through the wire outlet groove 530 and pulled out from the top of the diaphragm 53 and straightened in a crossed shape. The cotton threads 52 will be placed on the outer side wall of the shaping plate 3, so as to shape the arc and shape of the cotton threads 52. After trimming, the voice coil and diaphragm assembly 5 can be taken out from the whole-line fixture. Its structure is simple and easy to use, which can play an auxiliary role, greatly reduce the difficulty of whole-line, reduce working hours, improve production efficiency and reduce production costs.
[0018] Based on the above embodiments, the top surface of the shaping plate 3 is in the same plane as the top surface of the cylinder 1, which can provide better support for the sound film 53 and avoid the inclination of the product during the whole process.
[0019] Based on the above embodiments, avoiding inclined surfaces 20 are provided on both side walls of the window 2 to reduce the interference with the cotton thread 52 and ensure that the cotton thread 52 is led out in a streamlined manner.
[0020] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
