Embodiment approach

[0041] According to one embodiment of the present invention, the bottom of the semicircular groove 3 of the present invention is provided with a limiting opening 31 . When the vehicle-mounted camera module housing A is placed in the housing mounting portion 221 of the second module 22 , it is used to limit the vehicle-mounted camera module housing A.

[0042] combine figure 1 and Figure 7As shown, according to an embodiment of the present invention, the positioning plate 1 is provided with a through hole corresponding to the gap 24 shown. When performing laser welding on the vehicle-mounted camera module housing A, the optical fiber tube g of the laser transmitter is arranged in the through hole and connected to the upper port of the gap 24 so that the laser light reaches the welding surface along the gap 24 . Specifically, usually one of the upper and lower shells of the vehicle-mounted camera module is a transparent material, and the other is an absorbent material. The la...

Abstract

The invention relates to a laser welding jig, comprising a positioning plate (1) and a jig body (2) fixed on the positioning plate (1), the jig body (2) includes (1) a first module (21), a second module (22) and a third module (23) that are detachably connected; the second module (22) is located at the first module 21 and the third module ( There is a gap (24) between 23) and the first module (21) and the third module (23); the second module (22) is provided with a housing installation part (221). The laser welding jig of the present invention can solve the problem of alignment deviation between the laser position and the welding surface, and ensure that the welding effect meets the requirements.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a laser welding jig used for the plastic casing of a camera module. Background technique [0002] The existing side non-destructive laser welding equipment mainly consists of lasers, optical fibers and jigs. Therefore, the design of the fixture will directly lead to the quality of laser welding. The function of the jig is to realize the effective welding of the upper and lower shells of the vehicle-mounted camera module, so that the vehicle-mounted camera module can meet the waterproof requirements. [0003] Generally speaking, there is a certain processing error between the upper and lower shells of the vehicle-mounted camera module. The positions of the welding surfaces of the upper and lower shells of different vehicle-mounted camera modules are not exactly the same. This will require that the laser position should always correspond to the welding surface according to actual...
