Implantation method of memory alloy wire in miniature optical camera module

Abstract

The invention relates to a method for implanting a memory alloy wire in a micro-optical camera module, including S1, providing a jig, placing the memory alloy wire in a wire slot opened by the jig, and positioning one end of the memory alloy wire; S2, changing the jig The track line of the wire groove in the tool, the memory alloy wire deforms along the wire groove, so as to change the length of the memory alloy wire in the wire groove, cut the movable end of the memory alloy wire, and obtain a certain length of memory alloy wire parked on the wire of the jig In the groove; S3, restore the line groove trajectory in the jig, and move the memory alloy wire to the micro-optical camera module through the jig, and fix the two ends of the memory alloy wire with the micro-optical camera module; S4 1. Exit the jig, that is to complete the implantation of the memory alloy wire on the micro-optical camera module. The invention realizes grasping on the jig, adaptation adjustment and cutting, implanting the memory alloy wire to the micro-optical camera module for fixed connection, simple process, easy operation, and improved assembly efficiency and quality.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a method for implanting a memory alloy wire of a miniature optical camera module with an optical correction function. Background technique [0002] Miniature auto-focus cameras are widely used in mobile phones, cars, unmanned aircraft, security monitoring, smart home and other products. Ordinary miniature auto-focus camera modules are driven by a miniature voice coil motor to move the lens up and down in the direction of the optical axis. When taking pictures, the control chip drives the voice coil motor to move, thereby realizing the auto-focus function. When taking pictures or videos, the lens will not be able to keep absolutely stable due to human shaking or other reasons, resulting in a certain offset. At this time, the focus and light input of the camera will be affected, which will affect the quality of the image captured by the camera. Generally, this kind of lens deflect...

Problems solved by technology

But the existing miniature optical camera module that adopts memory alloy wire, its memory alloy wire implantation assembly method is: first measure and cut out the memory alloy wire of corresponding length, then grab memory alloy wire and assemble into the micro memory alloy wire On the optical anti-shake actuator, this implant assembly method has pre-cutting in actual operation, so that the length of the memory alloy wire cannot be adjusted according to the assembly requirements, and it is inconvenient to grab and assemble, which affects assembly efficiency and quality
