The structures of the conveying device, the cell edge sealing and tab leveling device 30, the cell detecting device 9 and the cell production waste recycling system in the cell processing production line will be described in detail below.
As shown in fig. 1, the conveying apparatus of the present embodiment may include at least two split conveying lines 11, a merging conveying line 12, and a conveying mechanism 13; the diverting conveyor line 11 is disposed upstream of the conveying apparatus 1, the converging conveyor line 12 is disposed downstream of the conveying apparatus 1, and the conveying mechanism 13 is disposed above the diverting conveyor line 11 and the converging conveyor line 12 and conveys the material on the diverting conveyor line 11 to the converging conveyor line 12 in a round-robin manner.
As shown in fig. 1 and 2, the split-flow conveyor line 11 and the merge-flow conveyor line 12 in the present embodiment each employ the same type of conveyor device. The split-flow conveyor line 11 and the combined-flow conveyor line 12 each include conveyor frames 111 and 121 and conveyor belts 112 and 122. The conveyor belts 112, 122 are mounted on the above-mentioned conveyor frames 111, 121 and driven by a power device (not shown) to convey the material from the split conveyor line 11 to the merging conveyor line 12.
As shown in fig. 1, the split-flow conveying lines 11 may be provided in two, the two split-flow conveying lines 11 and the converging conveying line 12 are provided in parallel, the head section of the converging conveying line 12 is located between the tail sections of the two split-flow conveying lines 11, and the conveying mechanism 13 can convey the material from the discharging position 113 of the tail section of the split-flow conveying line 11 to the feeding position 123 of the head section of the converging conveying line 12.

In one embodiment of the present invention, more than two split conveyor lines 11 may be provided, and then the material is conveyed to the split conveyor line 12 by the conveying mechanism 13. The present invention is not limited to the specific arrangement of the split-flow line 11 and the combined-flow line 12, and those skilled in the art can set the arrangement according to the actual situation.
As shown in fig. 1 and 2, in the present embodiment, stop blocks 114 and 124 are disposed at the tail sections of the split conveying line 11 and the converging conveying line 12, and the stop blocks 114 and 124 can stop and regulate materials. Stops 114, 124 may be disposed above the conveyor belts 112, 122 and coupled to the carriages 111, 121, but the stops 114, 124 do not impede the operation of the conveyor belts 112, 122. When the material is conveyed to the stop block 114, the stop block 114 can stop the material at the discharging position 113 of the split conveying line 11 and normalize the material so as to facilitate the conveying of the material by the conveying mechanism 13. And the stopper 124 functions similarly to the stopper 114, and will not be described again.

In an embodiment, a material handling device may be disposed on the split conveying line 11 to handle materials, and the combined conveying line 12 is used to simply convey materials. Since the material needs to be handled on the split conveyor line 11, the conveying speed of the split conveyor line 11 is smaller than that of the merging conveyor line 12. On some longer production lines, the step of carrying out complex treatment on materials adopts a material treatment device arranged on the split-flow conveying line 11, and the relative simple treatment step adopts a single split-flow conveying line 12 for conveying.
As shown in fig. 1 and 3, the conveying mechanism 13 may be disposed above the split conveying line 11 and the converging conveying line 12 through a bracket 14, and the bracket 14 may be made of square steel, but the present invention is not limited to specific materials and shapes, and a person skilled in the art may select the conveying mechanism according to practical situations. The handling mechanism 13 may specifically include a gripping device 131 and a driving device 132, and the driving device 132 drives the gripping device 131 to handle the material from the split conveyor line 11 to the merge conveyor line 12.

As shown in fig. 1, the two manipulators are a first manipulator 1311 and a second manipulator 1312, respectively, and the gripping device 131 is specifically configured such that the first manipulator 1311 moves above a diverting conveyor line 11 and grips the material located at the discharging position 113, then the first manipulator 1311 moves above the feeding position 123, and the second manipulator 1132 moves above the other discharging position 113, and the first manipulator 1311 places the material at the feeding position 123 while the second manipulator 1312 grips the material at the other discharging position 113, so as to complete the confluent conveying of the material in a cyclic reciprocation manner. By adopting the mode, the invention has the advantages that the structure is simple, the two manipulators cooperatively operate, the waste of working procedures does not exist, the reciprocating steps of the two manipulators can be effectively reduced when the materials are grabbed, the working efficiency of the conveying mechanism is greatly improved, and the efficiency of confluence conveying is effectively improved.
It should be understood that the foregoing embodiments are merely illustrative of the principles of the present invention and are not intended to limit the number and arrangement of the manipulators, and those skilled in the art may choose the number and arrangement of the manipulators according to practical situations, for example, when the split conveyor lines are plural, the manipulators may be plural in order to match the split conveyor lines.
