The connecting column 231 is made of high-strength rigid material, and the internal structure is hollow, which can reduce the weight while maintaining the structural strength.

[0055] In use, the rotating range of the rotary air cylinder 222 is usually controlled by the PLC. The limiting assembly 23 further prevents the rotary air cylinder 222 from rotating too much to cause the winding of the wire or the pipe. The output end of the rotary air cylinder 222 drives the connecting column 231 to rotate. The reset shutter 233 rotates with the connecting column 231, and the upper end of the reset shutter 233 is away from the sensing end of the opposite sensor 234. The limiting block 232 rotates with the connecting column 231, and gradually abuts with the limiting sliding block 236. The limiting sliding block 236 hinders the movement of the limiting block 232, and further hinders the rotation of the connecting column 231, thereby preventing the rotary air cylinder 222 from continuously rotating in one direction. Then the rotary air cylinder 222 reversely rotates, drives the connecting column 231 and the reset shutter 233 to rotate, until the upper end of the reset shutter 233 rotates back to the inside of the sensing end of the opposite sensor 234. The PLC sends a command to stop the rotation of the rotary air cylinder 222. At this time, the rotary air cylinder 222 drives the clamping mechanism 3 to return to the position before rotation, so as not to wind the wire and the pipe together, so as to facilitate the subsequent repeated work.

[0056] The implementation principle of the posture adjusting mechanism of the online testing device is as follows: when the device is used, first, the product to be tested is scanned and recognized, and is placed on the conveying belt 13 at the feeding port, and is conveyed to the inside of the device by the conveying belt 13, the posture adjusting mechanism 2 and the clamping mechanism 3 grasp the product to be tested, the clamping mechanism 3 is moved to the upper side of the product to be tested by the movement module 21, the clamp of the clamping mechanism 3 is kept in alignment with the product to be tested by the visual rotating assembly 22, then the clamping mechanism 3 clamps the product, the clamped product is moved to the testing area of the rotating testing mechanism 4 and is placed down by the movement module 21 and the visual rotating assembly 22, the tested product is conveyed to the conveying belt 13 at the offline port to complete offline, and the unqualified product is conveyed to the conveying belt 13 at the discharge port and is discharged.
