Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly, in particular to a positioning fixture used for battery assembly. Background Art

[0002] Alkaline zinc-manganese batteries are manufactured using a reverse polarity structure, with zinc as the negative electrode, manganese dioxide as the positive electrode, and sodium hydroxide or potassium hydroxide as the electrolyte. Alkaline zinc-manganese batteries are a high-performance upgrade from conventional dry-cell batteries. Available in two sizes: LR6 (AA) and LR03 (AA). These batteries are available in standard (0.60% mercury content) and trace mercury (less than 0.025% mercury content).

[0003] Currently, when producing alkaline zinc-manganese batteries, it is usually necessary to fill the inside of the battery with graphite powder. When filling the graphite powder to the top, the equipment for filling the graphite powder externally needs to move upward at the end of filling. This can easily cause the graphite powder on the top to slide to one side, causing it to spill to the outside and contaminate the equipment. Utility Model Content

[0004] In order to solve the problems in the prior art, the utility model provides a positioning fixture for battery assembly.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A positioning fixture for battery assembly includes a base, two guide sleeves are installed on the top of the base near the edges on both sides, a movable plate is arranged between the outer surfaces of the multiple guide sleeves, a plurality of through holes are opened at equal intervals on the top of the movable plate, the inner walls of the multiple through holes are correspondingly fitted with the outer surfaces of the guide sleeves, a plurality of hoppers are fixed at equal intervals on the top of the movable plate, the bottoms of the multiple hoppers all penetrate to the bottom, annular grooves are opened between the inner walls of the multiple hoppers near the bottom edges, a rubber membrane is fixed between the inner walls of the multiple annular grooves, and a plurality of blocking pieces are fixed at equal intervals on the outer surfaces of the multiple guide sleeves.

[0007] Optionally, a plurality of bridging holes are opened inside the movable plate, and two adjacent annular grooves are connected to each other through the bridging holes. A second pipe is fixed to one side of the movable plate, and one end of the second pipe passes through the interior of the annular groove.

[0008] Optionally, a plurality of guide grooves are formed on the outer surfaces of the plurality of guide sleeves at equal intervals, and sliders are slidably connected between the inner walls of the plurality of guide sleeves.

[0009] Optionally, multiple connecting plates are fixed on the outer surfaces of the multiple sliders, and the multiple connecting plates are correspondingly slidably engaged inside the guide groove, and one end of the multiple connecting plates is correspondingly fixed on the inner wall of the through hole, and a spring is fixed between the top of the slider and the inner top surface of the guide sleeve.

[0010] Optionally, mounting plates are fixed to the front and rear sides of the base near the bottom edge, clamping plates are fixed to both sides of the base, and movable handles are rotatably connected to both sides of the movable plate.

[0011] Optionally, an inner cavity is opened inside the base, and a first pipe connected to the inner cavity is fixed on one side of the base, and both the first pipe and the second pipe are provided with on-off valves.

[0012] Optionally, a plurality of storage slots are equidistantly provided on the top of the base, a through hole penetrating into the inner cavity is provided on the inner bottom surface of each of the storage slots, a gasket is provided on the inner bottom surface of the storage slot, and a battery shell body is provided inside the storage slot.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] 1. In the utility model, the battery shell body is first placed inside the storage tank, and then the movable plate is slid downward so that the rubber membrane on the hopper is located outside the battery shell body. Then, high-pressure air is introduced into the second pipe to expand the rubber membrane. During the expansion process, the battery shell body is pushed toward the middle part of the storage tank. Then, the first pipe is connected to the external negative pressure air pipe, so that there is negative pressure in the inner cavity, thereby adsorbing the bottom of the battery shell body.

[0015] 2. In the utility model, after graphite powder is injected into the battery shell body, the movable plate is slid upward, so that the graphite powder scattered on the outer shell or the top edge of the battery shell body can be gathered to the top of the battery shell body, and finally enter the top of the battery shell body again. After high-pressure gas is introduced into the second pipe, the high-pressure gas can flow into the interior of each annular groove through the bridge hole. After the movable plate is slid downward, the movable plate can be limited by the mutual engagement of the movable handle shell clamping plate. When the movable plate is reset, the elastic force of the spring facilitates the movable plate to slide upward. At the same time, when the movable plate slides to the top, it is blocked by the blocking piece to prevent slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The effect achieved by the entire embodiment 1 is as follows: first, the battery shell body 24 is placed into the storage tank 11, and then the movable plate 4 is slid downward so that the rubber membrane 16 on the hopper 7 is located on the outside of the battery shell body 24, and then high-pressure air is introduced into the second pipe 9 to expand the rubber membrane 16. During the expansion process, the battery shell body 24 is pushed toward the middle part of the storage tank 11, and then the first pipe 8 is connected to the external negative pressure air pipe so that there is negative pressure in the inner cavity 12, thereby adsorbing the bottom of the battery shell body 24.

[0028] Example 2, as Figure 1-5 As shown, a plurality of bridging holes 17 are provided inside the movable plate 4, and two adjacent annular grooves 15 are connected to each other through the bridging holes 17. A second pipe 9 is fixed on one side of the movable plate 4, and one end of the second pipe 9 passes through the inside of the annular groove 15. The outer surfaces of the plurality of guide sleeves 6 are equidistantly provided with a plurality of guide grooves 19, and the inner walls of the plurality of guide sleeves 6 are slidably connected with sliders 20.

Through the bridging hole 17, the high-pressure gas can flow into the inside of each annular groove 15, thereby expanding the rubber membrane 16. During the expansion process, the battery shell body 24 is pushed toward the middle part of the storage tank 11. Then the first pipe 8 is connected to the external negative pressure air pipe so that there is negative pressure in the inner cavity 12, thereby adsorbing the bottom of the battery shell body 24. After injecting graphite powder into the battery shell body 24, by sliding the movable plate 4 upward, the graphite powder scattered on the outer shell or top edge of the battery shell body 24 can be gathered to the top of the battery shell body 24, and finally enter the top of the battery shell body 24 again.
