Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] see figure 1 and figure 2 , the voice coil motor assembly jig 400 provided by the first embodiment of the present invention includes a base 500 and a cover 600 .

[0012] The base 500 includes a cube body 50 , two pairs of base legs 504 diagonally distributed around the body 50 , two pairs of positioning structures 503 , three support columns 502 , and two magnet slots (not shown).

[0013] The body 50 has a surface 501 and another surface 505 opposite to the surface 501 . The three support columns 502 are located on the surface 501 , and the line connecting the three support columns 502 is approximately an equilateral triangle, and the center of the equilateral triangle coincides with the center of the body 50 .

[0014] Each base leg 504 has an end surface 5041 , and a pair of base legs 504 has a positioning hole 5042 respectively, and the positi...

Abstract

The invention relates to an assembly fixture for a voice coil motor, which comprises a base and a cover body, wherein the base comprises a body, a pair of first fit parts which are in central symmetry distribution relative to the center of the base, a pair of positioning structures and a first magnet groove; the base body is provided with a first surface, and a second surface opposite to the first surface; the pair of positioning structures are in diagonal distribution relative to the centre of the base body and perpendicular to the first surface of the base body; the first magnet groove is positioned on the second surface of the base and used for accommodating a first magnet; the cover body comprises a body, a pair of second fit parts which are in central symmetry distribution relative to the cover body, and a second magnet groove; the body of the cover body is provided with a first surface, and a second surface opposite to the first surface; the second magnet groove is positioned on the second surface of the cover body and used for accommodating a second magnet and making the second magnet and the first magnet match to provide a magnetism; and the base and the cover body are relatively fixed through the clamping of the first fit parts and the second fit parts.

Description

technical field [0001] The present invention relates to a voice coil motor, in particular to a jig for assembling a voice coil motor. Background technique [0002] Currently, assembly of magnetic components is becoming more difficult with the miniaturization of voice coil motors and the inherently strong forces between the magnetic components. Traditionally, large-scale automatic magnetic component assembly machines are generally used to assemble magnetic components for voice coil motors. However, for researchers, if automatic magnetic component assembly machines are used for assembly verification in the design and verification stages of voice coil motors, then It is cost prohibitive and time consuming. Contents of the invention [0003] In view of this, it is necessary to provide a convenient jig for assembling magnetic components of a voice coil motor. [0004] A voice coil motor assembly jig, which is used to assemble magnetic elements for the voice coil motor, the vo...
