Vibration discharging device of elastic sheet input machine for voice coil motor

Abstract

The invention discloses a vibration discharging device of an elastic sheet input machine for a voice coil motor. The vibration discharging device comprises a frame body, and the frame body is composedof a top plate and two side plates, and further comprises eccentric mechanisms; the top plate is used for bearing trays; the two side plates are fixedly arranged on the two sides of the top plate; atleast three guide columns are arranged on the top plate in a protruding mode, are arranged aligned with guide holes in the bottoms of the trays and are used for positioning the trays; the eccentric mechanisms are driven by motors; output shafts of the motors are horizontally arranged; each eccentric mechanism comprises a semicircular eccentric block; the circle centers of the eccentric blocks arelocated on the axes of the output shafts of the motors; the eccentric blocks are driven by the motors to rotate; matched round holes are formed in the positions, corresponding to the eccentric blocks, in a machine frame of the elastic sheet input machine; the diameter of each matched round hole is larger than the diameter of each eccentric block; the eccentric blocks of the eccentric mechanisms extend into the matched round holes to be in transmission connection with the matched round holes so as to be configured to be that when the motors drive the eccentric blocks to rotate, the side wallsof the eccentric blocks generate regular impact on the inner walls of the matched round holes so as to drive the frame body to vibrate regularly relative to the machine frame of the elastic sheet input machine. According to the vibration discharging device, vibration is generated on the trays, and therefore carriers and elastic sheets in the trays can be accurately stacked in an aligned mode.

Description

technical field [0001] The invention relates to the processing field of a micro-camera voice coil motor, in particular to a vibration discharge device for a voice coil motor shrapnel inserting machine. The miniature camera can be assembled and applied to thin electronic products such as mobile phones, tablet computers, and smart watches. Background technique [0002] In existing designs of camera voice coil motors (VCM), its structure usually includes a carrier positioned in a housing composed of a yoke and a base. The carrier is provided with a through hole for assembling the lens of the camera; wherein, the outer circumference of the carrier is provided with a coil, and the corresponding coil is provided with a magnet in the yoke, so that when the coil is energized, the carrier can be displaced vertically due to electromagnetic induction , so as to realize the zooming and focusing of the camera; the upper and lower end surfaces of the carrier are also respectively positio...

AI Technical Summary

Problems solved by technology

Usually, in an ideal state, the carrier and the shrapnel should be aligned and stacked, but in the process of automatic production, it is difficult to ensure that the carrier and the lower shrapnel in each chute can be in the aligned state, so it is often caused by the two The deviation of the position leads to problems with the product yield of subsequent production
