Problems solved by technology

In order to ensure the vibration effect, most of the eccentric blocks currently used adopt an asymmetric structure, so that the center of mass does not coincide with the main shaft, resulting in an arc-shaped gap on the eccentric block. There is a problem with centering and positioning, and it is impossible to accurately insert and rotate the center hole of the eccentric block and the main shaft of the motor, which seriously restricts the degree of automatic assembly

Abstract

The invention provides a micro vibration motor with convenient assembly of balance weight blocks. The micro vibration motor comprises a motor body, a rear cover is installed on the tail part of the motor body, a power line is connected to the rear cover, and a combined balance weight block is installed on a main shaft of the motor body. The combined balance weight block comprises a hollow balanceweight block, and the hollow balance weight block and a solid balance weight block jointly form an integral cylinder balance weight block structure. The shape structure of the balance weight blocks ofthe micro vibration motor balance weight block adopts a cylindrical integral structure, the micro vibration motor can be matched with a feeding vibration plate and automatic motor assembling equipment to realize automatic feeding and assembling, fast and accurate positioning is ensured in the assembly process, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the field of micro motors, in particular to a micro vibrating motor which is convenient for assembling weights. Background technique [0002] Micro motors are widely used in all walks of life, especially in electronic products. Generally, vibration motors need to install eccentric weights on the main shaft, drive the main shaft through the motor, and then drive the eccentric weights to rotate by the main shaft, and finally achieve vibration. In order to ensure the vibration effect, most of the eccentric blocks currently used adopt an asymmetric structure, so that the center of mass does not coincide with the main shaft, resulting in an arc-shaped gap on the eccentric block, but due to the existence of the arc-shaped gap, it will cause it to fail during the automatic assembly process. There is a problem in the centering and positioning. It is impossible to accurately insert and rotate the center hole of the eccentric block and ...
