The invention provides a clamp for a square shell of a camera module and an assembly method thereof, which are used for making the purposes, the technical scheme and the effects of the invention clearer and more definite, and the invention is further described in detail below by referring to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 2, the fixture for a square housing of an image capturing module provided by the invention includes: the fixture comprises a fixture base 100, a middle fixing plate 200 and a fixture body 300 which are sequentially arranged from bottom to top, wherein the middle fixing plate 200 is detachably connected above the fixture base 100, and the fixture body 300 is detachably connected on the middle fixing plate 200. In contrast, the clamp body 300 and the middle fixing plate 200 need a connection structure that is convenient to disassemble, and the middle fixing plate 200 does not need to be disassembled, so the connection of the middle fixing plate 200 and the clamp body 300 should be mainly stable.
The jig base 100 includes: the base transverse plate 110 and a plurality of base longitudinal plates 120 arranged at intervals, wherein the base longitudinal plates 120 are fixedly connected to the upper end face of the base transverse plate 110, and the middle fixing plate 200 is detachably connected to the upper end face of the base longitudinal plate 120 and is parallel to the base transverse plate 110. A plurality of rotation driving sources 400 are detachably connected to the lower end surface of the middle fixing plate 200, and as shown in fig. 2, it is preferable that the rotation driving sources 400 are located at a gap between the adjacent base longitudinal plates 120. The upper end of the rotary driving source 400 is connected with a T-shaped blind rivet 410 as shown in FIG. 3. As shown in fig. 3 and 4, the clamp body 300 is provided with a fixing groove 317, and the fixing groove 317 corresponds to the position of the blind rivet 410. The fixing groove 317 is provided with two parallel cross bars 312 in a penetrating manner, the distance between the two parallel cross bars 312 is larger than the width of the blind rivet 410 and smaller than the length of the blind rivet 410, and the blind rivet 410 can rotate in the fixing groove 317 after passing through the gap between the two parallel cross bars 312 and entering the fixing groove 317, so as to fixedly connect the middle fixing plate 200 and the fixture body 300.
