The reject removing mechanism 23 may be a mechanism identical to the feeding mechanism 11, and the structure and operation principle of the second temporary storage mechanism 24 are identical to those of the first temporary storage mechanism 22, which will not be described herein.

The pairing feeding process in the embodiment has two modes: in the first pairing and feeding process, the first four batteries are transmitted to the incoming material level at the tail end of the battery by the incoming material detection mechanism 11, and if the first four batteries detected by the incoming material detection mechanism 12 are all qualified batteries, the pairing and material moving mechanism 21 directly transfers the four qualified batteries to the first temporary storage mechanism 22; if unqualified batteries exist in the first four batteries detected by the incoming material detection mechanism 12, the pairing and material moving mechanism 21 transfers the qualified batteries in the four batteries to the first temporary storage mechanism 22, and transfers the unqualified batteries in the four batteries to the unqualified product material removing mechanism 23. Then, the material receiving mechanism 11 continues to convey the four batteries to the material receiving position at the tail end of the material receiving mechanism, and if the four subsequent batteries are all qualified batteries, the pairing material moving mechanism 21 synchronously transfers the four qualified batteries to the conveying device 3; if unqualified batteries exist in the four subsequent batteries, the pairing and moving mechanism 21 transfers the unqualified batteries to the unqualified product material removing mechanism 23, at this time, the qualified batteries at the material coming position of the material supplying mechanism 11 are missing, then the pairing and moving mechanism 21 transfers the corresponding qualified batteries to the material coming position of the material supplying mechanism 11 from the first temporary storage mechanism 22, so that the batteries at the material coming position of the material supplying mechanism 11 are supplemented with the four qualified batteries, and then the pairing and moving mechanism 21 transfers the four qualified batteries to the conveying device 3. If the qualified batteries temporarily stored in the first temporary storage mechanism 22 are not enough to replenish the qualified batteries lacking in the incoming material level of the incoming material mechanism 11, the paired material moving mechanism 21 moves the qualified batteries of the incoming material level of the incoming material mechanism 11 to the first temporary storage mechanism 22 for temporary storage, and waits for the next replenishing and material taking. Thus, the four batteries transferred to the conveying device 3 synchronously by the paired material transferring mechanism 21 are all qualified batteries. In the second pairing feeding process, the first four batteries are conveyed to the material receiving position at the tail end of the battery by the material receiving mechanism 11, and if the first four batteries detected by the material receiving detection mechanism 12 are all qualified batteries, the pairing material moving mechanism 21 directly transfers the four qualified batteries to the conveying device 3. Then, the material receiving mechanism 11 continues to convey, and when the products subsequently conveyed by the material receiving mechanism 11 have unqualified products, the paired material moving mechanism 21 transfers the qualified batteries in the four batteries to the first temporary storage mechanism 22, and transfers the unqualified batteries in the four batteries to the unqualified product material removing mechanism 23. If unqualified batteries exist in the first four batteries detected by the incoming material detection mechanism 12, the pairing and material moving mechanism 21 transfers the qualified batteries in the four batteries to the first temporary storage mechanism 22, and transfers the unqualified batteries in the four batteries to the unqualified product material removing mechanism 23. The subsequent other completion processes are consistent with the first pairing feeding process, and are not described herein again.

The pairing blanking process of the pairing material moving mechanism 21 is similar to the pairing material loading process, and the pairing material moving mechanism also has two modes: in the first pairing blanking process, if all the four batteries transmitted by the clamp for the first time are qualified batteries in welding detection, the pairing material moving mechanism 21 directly transfers the four qualified batteries to the second temporary storage mechanism 24; if the welding-unqualified batteries exist in the four batteries firstly conveyed by the fixture, the pairing material moving mechanism 21 transfers the welding-qualified batteries in the four batteries to the second temporary storage mechanism 24, and transfers the welding-unqualified batteries in the four batteries to the unqualified product material removing mechanism 23. Then, the clamp continues to transmit the positions of the four subsequent battery pairing and moving mechanisms 21, and if the four subsequent batteries are all welding qualified batteries, the pairing and moving mechanisms 21 synchronously transfer the four welding qualified batteries to the intermediate blanking device 4; if the welding unqualified batteries exist in the following four batteries, the pairing material moving mechanism 21 transfers the welding unqualified batteries to the unqualified product material removing mechanism 23, at this time, the batteries in the clamp are lost, then, the pairing material moving mechanism 21 transfers the corresponding welding qualified batteries to the clamp from the second temporary storage mechanism 24, so that the clamp is filled with the four welding qualified batteries, and then, the pairing material moving mechanism 21 transfers the four qualified batteries to the blanking device 4. Therefore, the four batteries synchronously transferred to the blanking device 4 by the paired material transferring mechanism 21 are all welding qualified batteries. In the second pairing blanking process, the four batteries conveyed by the clamp for the first time are all welding qualified batteries, and then the pairing material moving mechanism 21 directly transfers the four welding qualified batteries to the blanking device 4. And then, the fixture is conveyed continuously, when the batteries conveyed subsequently by the fixture have unqualified batteries for welding, the pairing material-moving mechanism 21 transfers the qualified batteries for welding in the four batteries to the second temporary storage mechanism 24, and transfers the unqualified batteries for welding in the four batteries to the unqualified product material-removing mechanism 23. If the first four batteries conveyed by the fixture have unqualified welding batteries, the pairing material moving mechanism 21 transfers the four middle welding qualified batteries to the second temporary storage mechanism 24, and transfers the four middle welding unqualified welding battery removing mechanisms 23. The subsequent area completion process is consistent with the first pairing blanking process, and is not described herein again.

The above is merely an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
