[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0030] As Figure 1 shown, the present invention provides a preferred embodiment of a secondary battery processing device.

[0031] A secondary battery processing device, and referring to Figure 1 , the secondary battery processing device includes a battery conveying unit 1, an alkali injection plate conveying unit 2, a battery insertion unit 3, an alkali injection rack conveying unit 4 and an output unit 5. The secondary battery processing device further includes a workbench 6. The battery conveying unit 1, the alkali injection plate conveying unit 2, the battery insertion unit 3, the alkali injection rack conveying unit 4 and the output unit 5 are all fixedly arranged on the workbench 6.

[0032] Specifically, the battery conveying unit 1 is mainly used to convey the battery 10. The battery conveying unit 1 is fixed on the workbench 6, and the output end of the battery conveying unit 1 is docked with the battery inserting unit 3. After the battery 10 is loaded from the input end of the battery conveying unit 1, it is conveyed to the battery inserting unit 3 through the battery conveying unit 1.

[0033] Further, the alkali injection plate conveying unit 2 is mainly used to convey the alkali injection plate 20. The alkali injection plate conveying unit 2 is fixed on the workbench 6, and the output end of the alkali injection plate conveying unit 2 is docked with the battery inserting unit 3. The output end of the alkali injection plate conveying unit 2 is directly below the battery inserting unit 3. After the alkali injection plate 20 is loaded from the input end of the alkali injection plate conveying unit 2, it is conveyed to the output end of the alkali injection plate conveying unit 2 through the alkali injection plate conveying unit 2. At this time, the alkali injection plate 20 is directly below the battery inserting unit 3. When the battery 10 is conveyed to the battery inserting unit 3, the battery inserting unit 3 can push the battery 10 downward and make the battery 10 accurately inserted into the alkali injection plate 20 directly below the battery inserting unit 3.

[0034] Further, the battery inserting unit 3 is mainly used to insert the battery 10 at the output end of the battery conveying unit 1 into the alkali injection plate 20 at the output end of the alkali injection plate conveying unit 2. Since the alkali injection plate conveying unit 2 can convey the alkali injection plate 20 to directly below the battery inserting unit 3, when the battery 10 reaches the battery inserting unit 3, the battery inserting unit 3 can push the battery 10 downward and make the battery 10 inserted into the alkali injection plate 20 directly below the battery inserting unit 3.

[0035] Among them, it should be noted that the alkali injection plate 20 can be provided with multiple rows of alkali injection holes arranged in rows for accommodating the battery 10. The alkali injection plate conveying unit 2 conveys the alkali injection plate 20 to the battery inserting unit 3 and makes the first row of alkali injection holes on the alkali injection plate 20 directly below the battery inserting unit 3. When the first batch of batteries 10 is conveyed from the battery conveying unit 1 to the battery inserting unit 3, the battery inserting unit 3 pushes the first batch of batteries 10 downward into the first row of alkali injection holes on the alkali injection plate 20. Further, the battery inserting unit 3 pushes the alkali injection plate 20 forward and makes the second row of alkali injection holes on the alkali injection plate 20 directly below the battery inserting unit 3 to facilitate the insertion of the next batch of batteries 10. When multiple batches of batteries 10 are respectively inserted into multiple rows of alkali injection holes in the alkali injection plate 20, the battery inserting unit 3 pushes it to the output end of the alkali injection rack conveying unit 4.

[0036] Further, the alkali injection rack conveying unit 4 is mainly used to convey the alkali injection rack 30. The alkali injection rack conveying unit 4 is fixed on the workbench 6, and the output end of the alkali injection plate conveying unit 2 is docked with the input end of the output unit 5. The output end of the alkali injection plate conveying unit 2 is also docked with the output end of the battery loading unit 3. After the battery 10 is inserted into the alkali injection plate 20 through the battery loading unit 3 and enters the output end of the battery loading unit 3, when the alkali injection plate 20 containing the battery 10 enters the output end of the battery loading unit 3, the alkali injection rack conveying unit 4 places the alkali injection rack 30 at its output end above the alkali injection plate 20 containing the battery 10 and outputs it through the output unit 5.

When the front-back pushing module 33 pushes the battery 10 into the slots 311, the up-down pushing module 34 pushes the battery 10 in the slots 311 downward, so that the battery 10 is inserted into the alkali injection plate 20 below the up-down pushing module 34 to complete the battery loading.

[0039] In one embodiment, with reference to Figure 2 and Figure 4 , the front-back pushing module 33 is mainly used to push the battery 10 at the output end of the battery conveying unit 1 onto the limiting plate 31. The front-back pushing module 33 includes a front-back pushing cylinder 331 and a pushing block 332. The front-back pushing cylinder 331 can drive the pushing block 332 to move back and forth relative to the limiting plate 31 to continuously push the battery 10 into the limiting plate 31.

[0040] In one embodiment, with reference to Figure 2 and Figure 5, the up-and-down pushing module 34 includes a pushing column mounting plate 341 and a plurality of pushing columns 342.
