Problems solved by technology
A voice coil motor generally includes a base, a PIN foot, a lower shrapnel, a carrier, and an upper shrapnel, etc. The structural parts are complex and difficult to assemble. The conduction with the PIN pin adopts the welding method, which needs to go through multiple processes, the process flow is more complicated, and the setting of the hot riveting column will affect the fixing effect and static characteristics, and the welding will also cause the bad phenomenon that the conduction cannot be achieved. There is a risk of the glue breaking off after the fatigue test

The invention discloses a voice coil motor. The voice coil motor comprises a base and an lower elastic sheet; the base comprises a base body and at least one PIN mounted on the base body; the base isalso provided with a silver paste layer; and the lower elastic sheet and the base are glued and fixed through the silver paste layer, and the lower elastic sheet and the PIN are connected in a conducting manner through the silver paste layer. According to the voice coil motor, the lower elastic sheet and the base are glued and fixed through the silver paste layer; and compared with the prior art which needs thermal riveting fixation firstly, then welding fixation and finally dispensing fixation, the technological process is simplified, production efficiency is greatly improved, and firm fixation is achieved.
Description
technical field [0001] The present invention relates to the field of micro-motor technology, and more specifically relates to a voice coil motor. Background technique [0002] A voice coil motor is a micro-motor widely used in camera modules of electronic equipment to drive the focus of the lens. A voice coil motor generally includes a base, a PIN pin, a lower shrapnel, a carrier, and an upper shrapnel, etc. The structural parts are complex and difficult to assemble. The conduction with the PIN pin adopts the welding method, which needs to go through multiple processes, the process flow is more complicated, and the setting of the hot riveting column will affect the fixing effect and static characteristics, and the welding will also cause the bad phenomenon that the conduction cannot be achieved. There is a risk of the glue breaking off after the fatigue test. Contents of the invention [0003] In order to solve the disadvantages of the prior art, the present invention pr...
