Abstract

The invention relates to a lens feeding device capable of controlling force. The lens feeding device comprises a clamping seat provided with an upper limiting block and a clamping jaw and further comprises a base, a voice coil motor, an encoder, a servo driver and a controller, wherein the base is arranged right below the upper limiting block; the voice coil motor and the encoder are fixedly arranged on the base and are in circuit connection with the servo driver; the servo driver is in circuit connection with the controller; the motor stator of the voice coil motor is fixed on the base; a workpiece placement seat is arranged at the top end of the motor rotor of the voice coil motor; an induction component of the encoder is fixedly connected with the motor rotor; and a sliding mechanism isarranged between the voice coil motor and the base. The lens feeding device is compact, small and exquisite in structural design, precisely controls workpiece impact force through controlling the movement speed of the motor rotor by stages, enlarges the control range, improves the feeding stability, reduces the damage rate and improves the applicability.

Description

technical field [0001] The invention relates to the technical field of lens feeding, in particular to a lens feeding device with controllable force. Background technique [0002] In the mobile phone camera module assembly equipment, it is necessary to assemble the cmos sensor and the lens according to the appropriate position and angle. During assembly, the lens module needs to be translated to the right below the lens gripper, and then raised to withstand the upper limit. Then the jaws clamp the lens module. The upper limit block can ensure that the lens is accurate in height, position and direction, and it is level. However, it requires force to withstand the upper limit block. If the force is too large, the lens module will be damaged. The traditional technology often achieves up and down movement through cylinders or ball screws, and force control through air pressure, springs, etc.; the up and down movement of the cylinder cannot accurately control the speed, accelerati...
