In this way, after the body structure of the liquid crystal module is determined, the center position of the liquid crystal module placed on the detection index disc 220 will correspond to the detection station, so that the liquid crystal module is aligned with the detection station on the detection index disc 220, thereby facilitating subsequent optical detection.

[0031] Further, the body capturing piece 250 comprises a capturing frame 252 and a second image capturing device 254, the capturing frame 252 is arranged on the detection base 210, and the second image capturing device 254 is movably connected with the capturing frame 252, and the second image capturing device 254 is arranged towards the feeding mechanical arm 120.

[0035] It can be understood that, for the deviation correction positioning of the flexible circuit board of the liquid crystal module, the flexible circuit board of the liquid crystal module is relatively soft, and the position is not easy to capture. Therefore, the manual plugging positioning method is usually used. However, the manual plugging method not only takes too long to correct the deviation, but also has poor accuracy.

[0036] In order to improve the deviation correction accuracy of the flexible circuit board of the liquid crystal module, please refer to Figure 2 The module deviation corrector 230 includes a deviation support 23a and a positioning deviation part 23b.

In the embodiment, the first translation sliding rail 2322 serves as a moving track of the second planar translation structure 232b, that is, the second planar translation structure 232b moves along the track of the first translation sliding rail 2322, so that the second planar translation structure 232b moves in the first axial direction, the first driving motor 2324 provides kinetic energy for the second planar translation structure 232b, so as to facilitate the second planar translation structure 232b to slide on the first translation sliding rail 2322, the second planar translation structure 232b changes the position relative to the deviation bracket 23a, and the position deviation of the flexible circuit board in the first axial direction is corrected.

[0040] Further, referring to Figure 2 The second planar translation structure 232b comprises a second translation slide rail 2326 and a second driving motor 2328, the second translation slide rail 2326 is connected with the first translation slide rail 2322, the steering moving subelement 234 is slidingly arranged on the second translation slide rail 2326, and the second driving motor 2328 is used to drive the steering moving subelement 234 to slide on the second translation slide rail 2326.

The steering moving subelement 234 is connected with the first translation slide rail 2322 through the second translation slide rail 2326, and the steering moving subelement 234 slides on the second translation slide rail 2326, so that the steering moving subelement 234 moves relatively to the second translation slide rail 2326 and the first translation slide rail 2322, which facilitates the displacement of the steering moving subelement 234 in different directions, thereby facilitating the position correction of the flexible circuit board in different directions by the telescopic deviation corrector 236b.

[0041] In another embodiment, the moving direction of the second planar translation structure 232b is perpendicular to the moving direction of the first planar translation structure 232a, so that the steering moving subelement 234 performs omni-directional translation in a plane. In yet another embodiment, the telescopic direction of the telescopic deviation corrector 236b is perpendicular to the moving direction of the first planar translation structure 232a, and the telescopic direction of the telescopic deviation corrector 236b is also perpendicular to the moving direction of the second axial translation element.

The third driving motor 2344 adjusts the position of the telescopic deviation corrector 236b according to the collected images of the positioning and capturing camera 236a, i.e. rotates the telescopic deviation corrector 236b to the position to be corrected, so that the correction accuracy of the flexible circuit board is effectively improved.

[0043] Further, referring to Figure 3 The turning moving sub-component 234 further comprises a suspension bracket 2346 connected with the rotating shaft of the third driving motor 2344, and the suspension bracket 2346 is suspended on the axial moving sub-component 232.
