Problems solved by technology

[0003] However, in the process of assembling the magnetic components, due to the excessive repulsion between the magnetic components, it is difficult to install the magnetic components around the frame of the voice coil motor. If the magnetic components cannot be placed correctly, the subsequent dispensing process, the assembly of other components It is also difficult to complete, which affects the yield and quality of voice coil motors

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] see figure 1 The assembly jig 10 provided by the first embodiment of the present invention includes a magnetically permeable part 106 and a carrying platform 104 carrying the magnetically permeable part 106 .

[0023] The carrying platform 104 has a surface 1041 on which four positioning structures 105 are arranged. The positioning structures 105 are symmetrically distributed about the center of the carrying platform 104 and are used to fix the voice coil motor to be assembled.

[0024] The positioning structure 105 is a boss higher than the surface 1041, and a right-angle structure is provided at the intersection of the two surfaces facing the center of the carrying platform 104, which is designed to match the four right-angle vertices of the voice coil motor to be assembled. This structure can better fix the voice coil motor on the supporting platfo...

Abstract

The invention discloses a voice coil motor assembling jig which is used for mounting magnetic elements for a voice coil motor, the voice coil motor to be mounted is provided with a fixing frame used for refraining plural magnet holding parts for holding the magnetic elements; wherein, the assembling jig comprises a bearing pad and a magnetizer; the bearing pad is provided with a surface which is equipped with a plurality of positioning structures distributed in central symmetry with the bearing pad and used for fixing the fixing frame; and the magnetizer is located on the surface of the bearing pad and within the area limited by the plural positioning structures, and used for offsetting the repulsive force among the magnetic elements during the process of assembling the magnetic elements.The invention also provides a method for mounting magnetic elements by using the voice coil motor assembling jig.

Description

technical field [0001] The invention relates to a voice coil motor assembly jig, in particular to a jig for assembling magnetic elements of a voice coil motor and a method for using the jig. Background technique [0002] Voice coil motors are often used in camera modules as a driving structure for focusing and focusing, and mainly include voice coil motor frames, magnets, coils and other structures. Magnets are often attached around the frame to provide a magnetic field with a magnetic field direction outward from the center of the frame. This magnetic field interacts with the electromagnetic field generated by the energized electromagnetic coil to drive the lens or lens barrel to move. [0003] However, in the process of assembling the magnetic components, due to the excessive repulsion between the magnetic components, it is difficult to install the magnetic components around the frame of the voice coil motor. If the magnetic components cannot be placed correctly, the subse...
