During this process, the moving direction of the carrier 301 changes by 180°, and the electric rail joint 1 is completed. A switch of the docking state.

Specifically, in this embodiment, as shown in Figure 6, the left and right ends of the conveying line 3 and the return line 4 are provided with a lifting device 5, the lifting device 5 is, for example, a lift, and the carrier 301 drags the electric rail joint 1 to move to At the left end of the conveyor line 3, the computer 302 is removed from the carrier 301 after the inspection is completed, and the carrier 301 enters the lifting device 5 on the left, and the lifting device 5 drives the carrier 301 and moves downward, and then sends it into the return line from the left end 4. During this process, the carrier 301 and the rail connector 1 are always connected by wires, the moving direction of the carrier 301 changes by 180°, from right to left, and the rail connector 1 completes the plugging state once After entering the return line 4, the carrier 301 moves to the right end of the return line by dragging the electric rail joint 1 through the wire, and enters the lifting device 5 on the right side. After the lifting device 5 drives the carrier 301 to move upward, it is sent from the right end During this process, the carrier 301 and the electric rail connector 1 are still connected by wires all the time, the moving direction of the carrier 301 changes by 180°, from left to right, and the electric rail connector 1 is completed once. The switching of the plugged state; after entering the transmission line 3, the carrier 301 continues to drag the electric rail joint 1 to move to the left through the wires. At this time, the computer 302 can be put on the carrier for power-on detection. The tool 301 drags the electric rail joint 1 through the wire, and keeps looping. During this period, because the carrier 301 only moves horizontally, the electric rail joint 1 rotates with the electric rail 2 .

In the detection method applicable to the detection line of electronic equipment in the above solution, by setting a ring-shaped electric rail and setting a rotary joint group on the electric rail, the rotary joint group moves in circles on the electric rail without re-taking and placing , plugged in, the rotary joint group can be kept in the energized state, which effectively improves the shortcomings of the prior art that the joints need to be manually taken and placed from the electric rail, greatly improves the detection efficiency of electronic equipment on the detection line, and reduces the cost of electronic equipment.
