Description
Technical Field
The invention relates to the technical field of camera assembly, in particular to a memory alloy wire installation tool of a micro optical camera module with an optical correction function.
Background
The miniature automatic focusing camera is widely applied to products such as mobile phones, automobiles, unmanned planes, security monitoring, smart homes and the like. The common micro automatic focusing camera module is driven by a micro voice coil motor to drive a lens to move up and down in the direction of an optical axis, and the voice coil motor is driven to move through a control chip during photographing, so that the automatic focusing function is realized. When taking a picture or taking a picture, the camera lens can not keep absolutely steady because of the shake of people or other reasons, produces certain skew, and the focus and the light inlet amount of camera all can receive the influence this moment, and then influences the quality that the camera acquireed the image. Generally, such lens deflection occurs in a direction perpendicular to the optical axis, and the auto-focus voice coil motor can only drive the lens to move in the optical axis direction, so that the problem caused by such lens deflection cannot be solved. An optical anti-shake actuator is added on the basis of an automatic focusing voice coil motor to drive a lens to move in two directions vertical to an optical axis, so that the deflection of the lens can be compensated, and the camera is helped to acquire better image quality.
The real sense of the miniature optical anti-shake camera motor is a closed-loop control system, the gyroscope detects the shake parameters of the lens and feeds the shake parameters back to the camera module control chip, and the camera module control chip calculates the corrected angle or displacement according to the position information provided by the lens position sensor and sends an instruction to drive the anti-shake actuator to reach the specified position, so that the displacement deflection of the lens caused by shake is corrected, and better image quality is obtained by photographing or shooting.
In the prior art, the same method can be adopted in two directions perpendicular to the optical axis as driving the lens to move in the optical axis direction, that is, the method can be realized by adopting a miniature voice coil motor. The common miniature voice coil motor generates Lorentz magnetic force in a magnetic field by an electrified coil to drive the lens to move; however, to realize optical anti-shake, the lens needs to be driven in at least two directions, which means that a plurality of coils need to be arranged, and thus, the miniaturization of the whole structure is challenging. For this reason, the micro-actuator using the voice coil motor principle for optical anti-shake generally integrates a plurality of coils on one circuit board, which is called as FP coil, thereby solving the size problem of the optical anti-shake actuator. However, the micro vcm optical anti-shake actuator and the autofocus micro vcm are separate, and the lens is usually mounted in the autofocus micro vcm, and the lens is moved in a direction perpendicular to the optical axis, that is, the lens moves along with the autofocus micro vcm. Therefore, the assembly process of the micro optical anti-shake camera module is more difficult, and the structural reliability of the whole micro motor is reduced. Then, a micro optical camera module is provided, in which an auto-focus voice coil motor is driven by a memory alloy wire to move in a direction perpendicular to an optical axis, and the module includes a protective outer cover, a lens, the auto-focus voice coil motor, an image sensor module, and a micro memory alloy optical anti-shake actuator, in which the lens is fixed to the auto-focus voice coil motor, the micro memory alloy optical anti-shake actuator includes a lens mounting hole adapted to mount the lens, and the image sensor module transmits an image acquired by the lens. The automatic focusing voice coil motor is fixed on the micro memory alloy optical anti-shake actuator, and the control chip pulls the automatic focusing voice coil motor to move based on the length change of the memory alloy wire on the micro memory alloy optical anti-shake actuator, so that the shake compensation of the lens is realized. However, when the memory alloy wire of the existing micro optical camera module adopting the memory alloy wire is implanted and assembled, the traditional tweezers type clamp often has the situations of unstable clamping and wire dropping due to the tiny memory alloy wire, and the assembling efficiency and quality are affected.
