Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a multi-cell unified liquid injection mold for zinc-based batteries. Background Art

[0002] In the production process of zinc-based batteries, after the battery cell pole pieces are assembled and before they are put into the shell and sealed, the same electrolyte needs to be added to each cell. The current technology mainly has the following two methods: 1. Use manual weighing to weigh the amount of liquid required for each cell in a container, and then manually pour it into each cell cavity of the unfilled battery. Each battery has 8 cavities that need to be weighed 8 times to complete the filling. 2. Use equipment for automatic filling. The required weight is adjusted by a volumetric pump. After each battery cavity is filled, the filling position automatically moves to the next battery cavity for filling. After all 8 cavities are filled, the battery automatically flows to the next process.

[0003] In the existing technology, when the electrolyte enters the mold, it is not stirred, and the various components in the electrolyte cannot be ensured to be evenly mixed, resulting in uneven concentration. In addition, when the electrolyte is poured into the battery shell, the injection cavity is not sealed. Improper operation will cause the electrolyte to splash and affect the injection work. Therefore, we propose a multi-cell unified injection mold for zinc-based batteries to solve the above problems. Utility Model Content

[0027] The technical solution of this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of this embodiment, rather than all the embodiments.

[0029] Reference Figure 1-Figure 3 , a multi-cell unified liquid injection mold for zinc-based batteries, comprising:

[0030] Mold body 1;

[0031] There are multiple liquid injection ports 2, which are arranged in sequence on the mold body 1. Multiple limit ports 3 are respectively provided between the multiple liquid injection ports. Solution cavities 4 corresponding to the multiple liquid injection ports 2 are respectively provided in the mold body 1. The multiple solution cavities 4 are each provided with a capacity scale 5.

[0032] A stirring mechanism is provided in the mold body 1 and is used to stir and mix the electrolytes in the multiple solution cavities 4;

[0033] The sealing cover 7 is located on the mold body 1, and upper fixing plates 8 are fixedly installed on both sides of the sealing cover 7;

[0034] The mounting mechanism is provided on the mold body 1 and is used to mount and fix the sealing cover 7 to the mold body 1 .

[0035] In this embodiment, a handle 9 is fixedly provided at the top center of the sealing cover 7 . The handle 9 is arc-shaped, and the staff can cover the sealing cover 7 on the mold body 1 through the handle 9 .

[0036] In this embodiment, the stirring mechanism includes a rotating rod 10 rotatably connected to the mold body 1, and a plurality of stirring blades 11 are fixedly connected to the outer wall of the rotating rod 10 in sequence. The plurality of stirring blades 11 are respectively located in the plurality of solution cavities 4. When the plurality of stirring blades 11 rotate, the electrolyte in the plurality of solution cavities 4 can be stirred and mixed, thereby avoiding uneven concentration. One end of the rotating rod 10 is fixedly connected to a turntable 12, and a crank is fixedly provided at an eccentric position on one side of the turntable 12. The staff can drive the turntable 12 to rotate by the crank.

[0037] The two brackets 20 are respectively connected to the bottom of the two upper fixing plates 8, and the bottom ends of the two connecting rods 14 are fixedly connected to a cross joint 15. The two lower fixing plates 6 are provided with a cross slot 16. The two cross joints 15 are respectively located in the two cross slots 16. The two lower fixing plates 6 are provided with a spring slot 17. The inner wall of one side of the two spring slots 17 is fixedly connected with a return spring 18. One end of the two return springs 18 is fixedly connected with a slide 19. The two slides 19 are respectively slidably connected to the two spring slots 17 by the elastic force released by the two return springs 18, which can drive the two slides 19 to move and reset. One side of the two slides 19 is fixedly connected with a bracket 20. The two brackets 20 are respectively located on the two cross joints 15. The two brackets 20 can limit the two cross joints 15.

The setting of the pull ring 22 makes it convenient for the staff to drag the extension plate 21.

[0038] The implementation principle of a multi-cell unified liquid injection mold for a zinc-based battery in an embodiment of the present application is as follows: the mold body 1 is made of acrylic material, the mold body 1 is transparent, and the liquid content in the multiple solution cavities 4 can be clearly seen. The capacity scales 5 provided inside the multiple liquid cavities 4 are relatively reduced in the internal viewing angle refraction difference caused by the thickness of the cavity wall relative to the scales provided outside the liquid cavities 4. When the amount of electrolyte in the liquid cavities is different, the difference can be clearly seen. The multiple limit ports 3 are used to position the partition of the battery shell during liquid injection to prevent the electrolyte from being poured into the battery cell cavity. The electrolyte flows into other cavities by shaking. The amount of electrolyte can be freely added to multiple solution cavities 4 according to needs. It is only necessary to check the capacity scale 5 for confirmation before filling the battery. It is applicable to battery filling with different electrolyte amounts. Before filling, the electrolyte required for each cavity of the battery is separately divided and loaded into each liquid cavity 4. By pulling the two pull rings 22, the two extension plates 21 are driven to move. The two extension plates 21 drive the two slides 19 to move and compress the two reset springs 18. The two slides 19 drive the two brackets 20 away from the two cross slots 16, and then the sealing cover 4 is closed. Located on the mold body 1, at the same time, the two cross joints 15 are inserted into the two cross slots 16, the two pull rings 22 are released, and the elastic force released by the two return springs 18 drives the two slides 19 to move. The two slides 19 drive the two brackets 20 to move above the two cross slots 16 and contact the top surfaces of the two cross joints 15 to limit and fix the two cross joints 15, thereby achieving the installation between the sealing cover 7 and the mold body 1. The staff drives the turntable 12 to rotate by the crank, the turntable 12 drives the rotating rod 10 to rotate, and the rotating rod 10 drives multiple The stirring blade 11 rotates to stir and mix the electrolyte in multiple solution cavities 4 to avoid uneven concentration. The multiple limiting ports 3 of the injection mold body 1 filled with electrolyte are steadily placed against the partition of the required injection battery. Each limiting port 3 corresponds to a partition. Confirm that the multiple injection ports 2 of the injection mold body 1 are positioned above the battery cell cavity. Slowly lift the bottom surface of the injection mold and let the electrolyte slowly flow from the injection port 2 into the battery cell cavity until the electrolyte in the injection mold body 1 is completely poured into the battery cell cavity. Then remove the injection mold body 1 to complete the battery injection.

[0039] Example 2

[0040] The rest of the embodiment 2 is the same as the embodiment 1, except that a sealing sleeve 13 is provided on the outer wall of the rotating rod 10, and the sealing sleeve 13 is fixedly arranged on one side of the mold body 1. The rotating rod 10 can rotate in the sealing sleeve 13. The sealing sleeve 13 can be used to prevent the electrolyte from overflowing from the mold body 1 when the rotating rod 10 rotates. All structures in this application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.
