Specifically, as shown in fig. 1 and fig. 6, the discharging device includes a material receiving box 35 and two clamping assemblies, which are arranged on the machine table 1 on two sides of the charging and discharging station of the battery cell jig 2 and are used for clamping and opening the battery cell jig 2, the material receiving box 35 is arranged on the machine table 1 close to the charging and discharging station, and is specifically arranged on the machine table 1 at one end of the long block 20; the clamping assembly comprises a second vertical plate 36, a second mounting plate 37, a containing plate 38, a clamping plate 39, a first cylinder 40 and a second cylinder 41, the second vertical plate 36 is vertically arranged on the upper surface of the machine table 1, the first cylinder 40 is horizontally arranged on the side wall of the second vertical plate 36, the second mounting plate 37 is vertically and fixedly arranged on a telescopic shaft of the first cylinder 40, the containing plate 38 is provided with two containing plates 38, the two containing plates 38 are respectively and vertically arranged at two ends of the second mounting plate 37 along the horizontal direction, the clamping plate 39 is parallelly arranged between the two containing plates 38, the second cylinder 41 is horizontally and fixedly arranged on the side wall of one containing plate 38, an output shaft of the second cylinder 41 is fixedly connected to the side wall of the clamping plate 39, and the clamping plate 39 and the opposite containing plate 38 are fixedly arranged on one side of the placing box 11. After electric core welding in electric core tool 2, place board 3 and be located unloading station department on going up through the drive of horizontal drive arrangement, first cylinder 40 drive second mounting panel 37 in two centre gripping subassemblies that are located electric core tool 2 both sides removes to electric core tool 2 direction, thereby make electric core tool 2 be located between holding plate 38 and splint 39, then rethread second cylinder 41 drive splint 39 cooperation holding plate 38 centre gripping is placing box 11 one side, then the in-process of rethread first cylinder 40's telescopic shaft return stroke will be placed box 11 and opened, thereby conveniently take out electric core from electric core tool 2 and place in receiving box 35.

Further, as shown in fig. 6, the second mounting plate 37 is provided with an ejection assembly for ejecting the battery cells in the storage box 11. The ejection assembly comprises a third cylinder 42, a push plate 43, a plurality of ejector rods 44 and a third mounting plate 45 in a channel steel shape, the third mounting plate 45 is fixedly arranged on the second mounting plate 37 and far away from the side wall of the accommodating plate 38, the ejector rods 44 are fixed on the side wall of the push plate 43, the push plate 43 is positioned between the third mounting plate 45 and the second mounting plate 37, the third cylinder 42 is mounted on the third mounting plate 45, the telescopic shaft of the third cylinder 42 is fixed on the side wall of the push plate 43 far away from the ejector rods 44, and the telescopic shaft of the first cylinder 40 is fixed on the side wall of the third mounting plate 45 in a dislocation manner. The side wall of the third mounting plate 45 is provided with third abdicating holes 46 corresponding to the plurality of spot welding holes 14 on the side plate 12, and the third abdicating holes 46 are used for the mandril 44 to extend out. The placing box 11 is opened through the clamping assembly, then the pushing plate 43 is pushed through the third air cylinder 42 in the ejection assembly, so that the plurality of ejector rods 44 on the pushing plate 43 extend out of the third abdicating hole 46 to push out the electric core in the electric core hole 13 in the spot welding hole 14, and then the electric core is placed in the material receiving box 35, and therefore the electric core discharging efficiency is further improved. A guide rod 47 is arranged between the second mounting plate 37 and the third mounting plate 45, a guide hole 48 is formed in the push plate 43, the guide rod 47 is movably inserted into the guide hole 48, and the guide hole 48 in the push plate 43 moves along the guide rod 47, so that the moving stability of the push plate 43 is improved.

The implementation principle of the embodiment is as follows: place electric core tool 2 that will be equipped with electric core on placing board 3, fix electric core tool 2 on placing board 3 through fixing device, then remove electric core tool 2 from last unloading station to the welding station through horizontal drive arrangement of rethread, rethread thrust unit and cooperation vertical mobile device drive electric bonding tool 4 welds the multirow electric core in electric core tool 2 afterwards, electric core welds good back, place board 3 and remove to last unloading station through horizontal drive arrangement drive of rethread, then open electric core tool 2 through centre gripping subassembly, then electric core in electric core tool 2 is ejecting to the ejecting subassembly of rethread, then manual collection is in collecting box 35 again, thereby production efficiency has been improved, the cost of labor has been reduced.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
