Problems solved by technology

However, due to its small size and high assembly precision requirements, it is inevitable to transfer its size during the manufacturing process. It is obviously not efficient to make it manually, and inappropriate manufacturing methods will easily cause voice coil motor assembly. The accuracy cannot meet the requirements, or even damage, increasing the defective rate
At present, in the process of laser welding and assembly of voice coil motors, the labor intensity of workers is high, the production efficiency is low, the assembly accuracy is poor, and the yield rate is not high, which will greatly increase the production cost of the enterprise.

Embodiment Construction

[0027] The following will describe in detail with reference to the drawings in the embodiments of the present invention.

[0028] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , a method for laser welding and assembly of rectangular voice coil motors, the first step is to fix the shell assembly 60 of the product on the positioning area 10 of the working base 7, and make the pins 11 of equal height in the positioning area 10 pass through The hollow part of the housing assembly 60 . In the second step, the shell assembly 60 is sucked and fixed in the Z-axis direction through the sucking hole 12 on the sucking bottom plate. In the third step, use the four-claw clamp 2 to position the housing assembly 60 in both directions of the X and Y axes to the middle at the same time. Fourth, positioning the positioning mechanism with a pair of tabs 27 to the inner side wall of the housing assembly 60 . In the fifth ste...

Abstract

The invention relates to the technical field of voice coil motor processing, in particular to a method suitable for laser welding assembly of a rectangular voice coil motor. The method mainly comprises the steps that a shell assembly of a product is placed on an adsorption base plate firstly, height-equal pins on the adsorption base plate penetrate through a hollow-out part of the shell assembly,and the shell assembly is adsorbed through a vacuum opening in the adsorption base plate; the shell assembly is positioned through a four-clamping-claw air cylinder, a sheet positioning mechanism is positioned to the inner side wall of the shell assembly, and a tungsten steel assembly is placed into the shell assembly; and an elastic sheet assembly in the tungsten steel assembly is adjusted through an elastic sheet assembly position adjusting mechanism, then the inner side wall of the shell assembly and an elastic sheet in the tungsten steel assembly are subjected to laser welding through a laser welding device, the positioning mechanism is released and removed, and a primary technological cycle is completed. According to the method for laser welding assembly of the voice coil motor, the assembly precision is effectively ensured, the yield is increased, and the production cost is an enterprise is reduced.

Description

technical field [0001] The invention relates to the technical field of voice coil motor processing, in particular to a laser welding and assembling method suitable for rectangular voice coil motors. Background technique [0002] A voice coil motor is a type of motor. Because the principle is similar to that of a speaker, it is called a voice coil motor. The voice coil motor has the characteristics of high frequency response and high precision. The main principle is to control the stretching position of the spring leaf by changing the DC current of the inner coil of the motor in a permanent magnetic field, thereby driving up and down movement. Because of its relatively simple structure and extremely small volume, it is widely used in smart wearable devices. [0003] The voice coil motor is mainly composed of four parts: the mover, the stator, the upper cover assembly, and the lower cover assembly. Each part must be assembled through multiple processes. However, due to its ...
