The horizontal rotating part 691 and the vertical moving part 692 are hinged through a rotating sleeve mechanism 64. The rotating sleeve mechanism 64 is driven to rotate by a rotating motor 62 so that the horizontal rotating part 691 rotates. The rotating sleeve mechanism 64 and the camera light source 65 have a through-hole structure that will not block the male connector terminal detection CCD camera 63 from collecting images. The male connector terminal detection CCD camera 63, the camera reflector 66 and the camera light source 65 are located on the horizontal rotating part 691. The upper and lower motors 61 are installed on the vertical moving part 692. The upper and lower motors 61 realize the vertical movement of the horizontal rotating part 691 through a ball screw driving structure; the horizontal rotating part 691 rotates to different positions so that the camera reflector 66 can collect images of the PIN133 in the inner holes 131 of multiple male connector terminals, such as Fig. 9 shown.

[0062] The detection method of the CCS integrated busbar offline detection machine of the present invention comprises the following steps:
[0063] Step 1: Place the CCS integrated busbar 1 on the fixture mobile platform module 2;
[0064] Step 2: Start the upper line-of-sight scanning camera module 31 and the lower line-of-sight scanning camera module 41 to start photographing the front and back sides of the CCS integrated busbar 1.
[0065] Step 3, start the upper linear motor slide module 3 and the lower linear motor slide module 4, so that the upper line of sight scanning camera module 31 and the lower line of sight scanning camera module 41 take pictures of all areas on the front and back of the CCS integrated busbar 1, and the image is sent to the control unit for preset data comparison to determine whether the welding piece is missing from the front of the CCS integrated busbar, whether the number of welding points is correct, whether hot riveting is not performed or whether the hot riveting points are damaged, and whether the aluminum bar is installed upside down; whether the thermal pad is missing from the back of the CCS integrated busbar.
[0066] Step 4. When all areas on the front and back sides of the CCS integrated busbar 1 are photographed, the upper linear motor slide module 3 continues to move so that the male connector terminal detection rotating module 6 is located above the male connector terminal. By controlling the upper and lower motors 61 and / or the rotating motor 62, the male connector terminal detection CCD camera 63 obtains the image of the PIN 133 in the inner hole 131 through the reflection of the camera reflector 66, and determines whether the inner hole PIN of the male connector terminal is deformed or whether there is foreign matter.
[0067] Alternatively, when all areas on the front and back of the CCS integrated busbar 1 are photographed, the upper linear motor slide module 3 and the lower linear motor slide module 4 continue to move so that the upper light source module 51 for detecting the female connector terminal and the lower light source module 52 for detecting the female connector terminal are close to the female connector terminal detection camera module 5, and the female connector terminal detection camera module 5 checks whether the PIN pin socket of the female connector terminal is deformed.
[0068] Step 5: When the control unit determines that all images are qualified, the CCS integrated busbar 1 is a qualified good product; otherwise, it is a defective product.
[0069] Among them, in step 4, when the side opening 132 of the male connector terminal is tilted, the tilt angle of the camera reflector 66 is adaptively changed by adjusting the first angle adjustment motor 67 and the second angle adjustment motor 68, and the area or size of the side opening 132 finally obtained by the male connector terminal detection CCD camera 63 is consistent with the preset value, and the area or size of the side opening 132 is used as a reference object to determine whether the rotation position of the camera reflector 66 is correct.
