Lens assembling mechanism

Abstract

The present invention discloses a lens assembling mechanism comprising a base, a slide carriage, a voice coil linear motor, a rotary drive device and a gripping device, the base being mounted on a moving frame and movable along with the moving frame above a lens fetching station and a lens assembling station. The slide carriage is mounted on the base and moves vertically along the base. The voice coil linear motor is mounted on the base and used for driving the slide carriage to move vertically along the base. The rotary drive device is mounted on the slide carriage and moves vertically. The gripping device is mounted a lower part of the rotary part of the rotary drive device and can rotate under the driving of the rotary part. The gripping device grips the lens at the lens fetching station, and presses the lens into a lens barrel and loosens the lens at the lens assembling station. The mechanism can be used in the process of assembling the lens to avoid the situation that the lens assembly is not in place or the lens is crushed due to the insufficient pressure or the large pressure, and the success rate of the lens assembly is improved.

Description

technical field [0001] The invention relates to the technical field of lens assembly, in particular to a lens assembly mechanism of a lens. Background technique [0002] Existing electronic products (such as mobile phones, tablet computers, notebook computers, and e-books, etc.) are basically equipped with camera lenses. The lens generally includes a lens barrel and a plurality of lenses installed in the lens barrel. The lens and the lens barrel are produced separately. After production, the separated lenses need to be packed into the lens barrel. The traditional lens assembly work is carried out manually, but due to the small size of the lens, manual assembly has the problems of low assembly efficiency and assembly accuracy, and the corresponding assembly cost is high. [0003] In order to improve the assembly efficiency, the existing technology uses the manipulator on the lens assembly equipment to assemble the lens. Generally, the manipulator first grabs the lens from th...

AI Technical Summary

Problems solved by technology

Although this method can replace manual labor to improve efficiency, due to the small size of the lens and high requirements for assembly accuracy, it is difficult for the existing manipulator to ensure micron-level vertical movement in the process of pressing the lens down into the lens barrel. Accuracy requirements

Therefore, in the process of assembling the lens, the manipulator is prone to the situation that the lens is not assembled properly or the lens is crushed due to insufficient pressure (caused by too small moving distance) or excessive pressure (caused by too large moving distance)
