[0054] The battery string gluing device also includes a conveying mechanism 8, an NG material recovery mechanism 9 and a third conveyor line 3. The NG material recovery mechanism 9 and the third conveyor line 3 are both located on one side of the second conveyor line 12; the conveying mechanism 8 is used to convey the battery string conveyed by the second conveyor line 12 to the NG material recovery mechanism 9 or the third conveyor line 3.

Driven by the transverse movement module 85, the transverse movement frame 81 moves horizontally, thereby driving the connecting column 82 and the second suction cup assembly 83 to move between the second conveyor line 12 and the NG material recovery mechanism 9 / third conveyor line 3.

[0059] The powered clamping assembly 86 includes a fixed base 861 connected to the connecting post 82, a conductive block 864, an insulating plate 862 rotatably mounted on the fixed base 861, and a first rotary drive member 863. The first rotary drive member 863 drives the insulating plate 862 to rotate relative to the fixed base 861, so that the insulating plate 862 and the conductive block 864 cooperate to clamp and secure the end of the welding ribbon. In this embodiment, the first rotary drive member 863 is preferably a servo motor.

[0060] When performing EL testing, two energized clamping components 86 are used to clamp and fix the two solder ribbon ends of the battery string adsorbed and fixed by the second suction cup component 83; driven by the second rotating drive component 88, the connecting column 82 rotates, driving the second suction cup component 83 and the adsorbed and fixed battery string to rotate together, so that the EL camera 87 can take an image of the battery string.

[0061] The transport mechanism 8 can flip the battery strings to a certain angle to facilitate imaging by the EL camera 87. After EL testing, battery strings that pass the EL test are directly transported to the third conveyor line 3, while battery strings that fail the EL test are transported to the NG material recovery mechanism 9, achieving the purpose of EL testing and sorting the battery strings.

Among them, the lifting material receiving line 31 includes two material receiving and conveying assemblies that move synchronously. The structure of these two material receiving and conveying assemblies is basically the same as that of the two conveying assemblies 2. The difference is that the connecting frames 21 of the two material receiving and conveying assemblies are connected by a connecting plate, and the connecting plate is connected to a lifting cylinder that drives it to rise and fall. When the EL test is qualified, the lifting cylinder drives the connecting plate to move upward, driving the two material receiving and conveying assemblies to move upward together to receive the battery strings adsorbed and fixed by each second suction cup assembly 83; the two material receiving and conveying assemblies move downward together and reset and then move together to convey the battery strings to the battery string output streamline 32. Among them, the battery string output streamline 32 is preferably a belt conveyor line.
