Embodiment 2

[0025] Such as figure 1 , figure 2 In the shown embodiment, a VCM coil fixture device includes a positioning shaft 1 and a positioning seat 4, wherein the positioning seat includes a seat body 4b and a positioning plate 4a, and the top of the seat body is provided with a positioning device for positioning the VCM coil 3 in the circumferential direction. The slot 404, since the VCM coil is octagonal, the positioning slot in this embodiment is also octagonal, corresponding to each side of the VCM coil. The edge of the positioning groove is provided with a positioning protrusion 402, the inner side of the positioning protrusion is flush with the inner side wall of the positioning groove, and the thickness of the positioning protrusion is smaller than the depth of the positioning groove on the VCM coil.

[0026] combine image 3 As shown, the center of the positioning groove is provided with a guide post 4c, the center of the seat body is provided with a through hole for accomm...

Abstract

The invention discloses a VCM coil clamp. The VCM coil clamp comprises a positioning shaft and a positioning seat, wherein the positioning seat comprises a seat body and a positioning plate; the positioning plate and the seat body are elastically connected; a positioning groove for circumferentially positioning the VCM coil is formed in the top of the seat body; a guide column fixed with the seatbody is arranged in the center of the positioning groove; a positioning hole matched with the guide column is formed in one end of the positioning shaft; and the edge of the positioning hole is provided with a transmission bulge for driving the VCM coil to rotate. The invention aims to provide the VCM coil clamp for improving coil winding efficiency.

Description

technical field [0001] The invention belongs to the field of VCM coil manufacturing, and in particular relates to a VCM coil clamp device. Background technique [0002] VCM (English: Voice Coil Motor) linear motor, also known as voice coil motor, is a kind of motor. Its main principle is to control the stretching of the spring leaf by changing the DC current of the inner coil of the motor in a permanent magnetic field. position, thereby driving up and down movement. In the camera of a smartphone, a VCM linear motor is needed, which can adjust the position of the lens to change the focal length, so that the camera can show the clearest state. For example, Chinese Patent Publication No. CN204349757U discloses a VCM linear motor, which includes an antimagnetic cover, a front shrapnel, a magnet, a coil, a carrier, a rear shrapnel, and a base. The rear shrapnel includes an inner spring part, an outer spring part, and a connecting part. The connection part is connected between t...
