In order to facilitate sorting, the first discharging mechanism 410 and the second discharging mechanism 420 are only provided with a single second gripper 413. However, since the first feeding mechanism 310 and the second feeding mechanism 320 are both provided with two first grippers 313, the feeding and discharging efficiencies are not matched, which easily affects the overall detection efficiency.

The first discharging mechanism 410, the second discharging mechanism 420 and the third discharging mechanisms 430 can drive the second clamps 413 to move along the Y-axis direction to above the flow line 600, so that each second clamp 413 corresponds to one first material discharging position, and then drive the second clamps 413 to move downward along the Z-axis direction to place the qualified batteries 800 on the conveying line to the corresponding second carriers 610.

The electrode detection mechanism 510 and the core surface detection mechanism are structures known in the art, and the present application will not be described here.

[0067] The two detection devices 500 are arranged staggered along the X-axis direction, so that the first conveying line 100 and the second conveying line 200 can be more compact while being limited by each other, and since the first conveying line 100 and the second conveying line 200 are arranged staggered along the X-axis direction, the staggered degree of the two detection devices 500 is the same as the staggered degree of the two conveying lines, so that the batteries 800 on the first conveying line 100 and the second conveying line 200 can be tested synchronously, that is, when the batteries 800 on different conveying lines move the same stroke, they are in the same detection position.

[0068] The working process of the double-channel visual inspection system is as follows: the flow line 600 moves the second carrier 610 carrying the battery 800 to each taking position, the first feeding mechanism 310 and the second feeding mechanism 320 are moved to the flow line 600 to grasp the battery 800 at the corresponding taking position, and then are moved to the corresponding conveying line to place the battery 800 at each first feeding position and second feeding position. In this process, the flow line 600 drives the empty second carrier 610 to move, so that the second carrier 610 corresponds to each placing position one by one, and ensures that the subsequent battery 800 can continue to flow to the taking position; the first conveying line 100 and the second conveying line 200 drive the battery 800 to flow through each detection position of the detection device 500 in turn, and finally move to the first discharging position and the second discharging position. The first discharging mechanism 410 and one of the third discharging mechanisms 430 can selectively move the battery 800 that passes the detection from the first conveying line 100 to the empty second carrier 610, or move the battery 800 that fails the detection to the transfer line 712. The second discharging mechanism 420 and the other third discharging mechanism 430 selectively move the battery 800 that passes the detection from the second conveying line 200 to the empty second carrier 610, or move the battery 800 that fails the detection to the transfer line 712. The flow line 600 can output the battery 800 that passes the detection to a preset position, and the transfer line 712 can input the battery 800 that fails the detection to the buffer line 721. Whenever the buffer line 721 receives a battery 800, it drives the battery 800 to move a preset distance to prevent the continuous inflow of the battery 800 on the transfer line 712, and when the buffer line 721 is full, the transfer line 712 is lifted to another buffer line 721 under the drive of the lifting module 711.

[0069] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the specification and drawings, is also included in the patent protection scope of the present application.
