Mobile phone camera LENS automatic locking jig and locking device and method

Abstract

The invention discloses a mobile phone camera LENS automatic locking jig and an automatic locking device. The locking device comprises a driving mechanism, a locking platform, a shaft sleeve and the locking jig. The locking jig comprises a rotary shaft, a coupler, a low-power motor and a programmable switching module, and the programmable switching module comprises an IGBT. A first groove matchedwith the upper surface of a camera LENS is formed in the bottom of the rotary shaft, and the first groove is used for fixing the upper surface of the camera LENS. By means of the automatic locking device, a voice coil motor is firstly placed on the locking platform, the voice coil motor is sleeved with the shaft sleeve, and the locking jig is moved to the position over the shaft sleeve. Then the driving mechanism is started, the locking jig is moved downwards till the rotary shaft reaches the upper surface of the shaft sleeve, and meanwhile the driving mechanism gives a trigger signal to the IGBT; and the low-power motor is started, rotation of the rotary shaft is controlled, and automatic locking of the camera LENS is achieved. According to the mobile phone camera LENS automatic locking jig and the automatic locking device, automatic and precise locking of the mobile phone camera LENS and the voice coil motor is achieved through an integral structure.

Description

technical field [0001] The invention relates to the technical field of mobile phone cameras, in particular to a mobile phone camera LENS automatic locking jig, locking device and locking method. Background technique [0002] Voice coil motor is a kind of motor, which is widely used in the camera of mobile phone. The existing mobile phone camera module includes a LENS (lens), and a voice coil motor connected to the LENS. The upper part of the front of the voice coil motor has a through hole for LENS to be pressed in. The LENS is arranged on the upper part of the front of the voice coil motor. When the LENS is locked with the voice coil motor 2, it is locked with the focus ring or automatic equipment. The defect of the focus ring or the traditional lock fixture is that the locking height and the flatness of the lens cannot be controlled, which may easily cause the lens to be crooked or locked. The VCM shrapnel is broken, and the locking work of the existing mobile phone camer...

AI Technical Summary

Problems solved by technology

The existing mobile phone camera module includes a LENS (lens), and a voice coil motor connected to the LENS. The upper part of the front of the voice coil motor has a through hole for LENS to be pressed in. The LENS is arranged on the upper part of the front of the voice coil motor. When the LENS is locked with the voice coil motor 2, it is locked with a focus ring or automatic equipment. The focus ring or the traditional locking fixture has the disadvantage of being unable to control the locking height and the flatness of the lens, which may easily cause the lens to be crooked or locked. The VCM shrapnel is broken, and the locking work of the LENS of the existing mobile phone camera and the voice coil motor is mostly completed by manual operation, but the lens size is small, which makes the manual efficiency very low
