Voice Coil Motor (VCM) magnetic sheet assembly device

Abstract

The invention discloses a Voice Coil Motor (VCM) magnetic sheet assembly device. The device comprises a bench, a feed system, a feeding system, a carrying system and a control system, wherein a feeding hole is arranged on the bench, the feed system which is used for feeding a magnetic sheet to the feeding hole is arranged at the position of the inside of the bench, which corresponds to the magnetic sheet installation position, the feeding system which is used for automatically assembling the magnetic sheet fed by the feed system to motors to be assembled is arranged at the position of the upper portion of the bench, which corresponds to the feeding hole, the carrying system which is used for fixing the motors to be assembled is arranged at the position of the lower portion of the bench, which corresponds to the feeding device, and the control system is used for controlling the working of the feed system, the feeding system and the carrying system. The feeding system which moves vertically is matched with a magnetic sheet feed system, magnets sheets which are required to be assembled are assembled to the carrying system for fixing the motors to be assembled one time, the carrying system is set to move along an X axis and a Y axis, a plurality of motor fixing groove for fixing motors to be assembled are fixedly arranged on a fixture carrier, a plurality of motors can be assembled continuously, and the production efficiency and the pass percentage are improved.

Description

technical field [0001] The invention relates to the technical field of voice coil motor manufacturing, in particular to a VCM motor magnetic sheet assembly device and a method for assembling strip-shaped thin magnetic sheets using the assembly device. Background technique [0002] VCM is Voice Coil Motor, commonly known as voice coil motor or voice coil motor. Voice coil motor is a special form of direct drive motor, which has the characteristics of simple structure, small size, high speed, high acceleration, and fast response. Its working principle is that a force will be generated by placing an electric coil (conductor) in a magnetic field, and the magnitude of the force is proportional to the current applied to the coil. Based on this principle, the movement form of the voice coil motor manufactured can be a straight line or a circular arc. [0003] At present, the assembly methods of the magnetic sheets inside the VCM motor mostly adopt the following two methods: [00...

AI Technical Summary

Problems solved by technology

Although adopting this device to assemble the magnetic sheets can reduce the labor intensity of the operators to a certain extent, it has the following defects: a, because it also installs the magnetic sheets one by one, resulting in low production efficiency; b, in the At the end of the installation, it needs to be pasted with glue, which increases the assembly process. On the one hand, the structure of the production equipment is complicated and the cost is increased. On the other hand, the magnetic sheet is glued to the fixed frame. Or it is very inconvenient when the surface of the magnetic sheet is scratched and needs to be replaced, and when the magnetic sheet needs to be replaced later, it is also necessary to deal with the glue pasted on the fixed frame, which complicates the replacement work
