Description

Technical Field

[0001] This utility model relates to the field of storage battery production technology, specifically to an acid injection pot for storage battery formation. Background Technology

[0002] After the battery plates, separators, and casing are assembled, the battery needs to undergo its first charge and discharge cycle, which involves adding an electrolyte such as dilute sulfuric acid into the battery. This process is called the battery formation process. The formation of the battery mainly involves the formation of active materials and an SEI film on the plates in order to activate the battery for use. During the battery formation process, dilute sulfuric acid needs to be added between the battery plates using an acid filling pot. When using an acid filling pot, the pot contains corrosive electrolyte, and the spout is the key part from which the liquid flows out. If it is placed carelessly, the spout may come into contact with the ground or work surface, which may cause multiple risks: spout contamination will affect the purity of the electrolyte, residual acid will corrode the work surface, and operators may accidentally touch it, causing safety hazards. Existing acid filling pots usually have a support frame. However, as mentioned in the authorization announcement number CN222261322U "An Acid Filling Pot for Battery Production and Processing", the existing support mechanism for acid filling pots has the problem of not being able to support the pot when acid is not being added to the battery, and the spout of the acid filling pot can easily come into contact with the support surface. Utility Model Content

[0003] This utility model addresses the problem that the support frame of an acid injection pot is difficult to support when the pot is not in operation. It provides an acid injection pot for battery formation that prevents the spout from contacting the support surface when the pot is not in operation.

[0004] To solve the above problems, the technical solution of this utility model is: A battery formation acid filling pot includes a pot body, with multiple pot bodies connected sequentially from left to right to form an acid filling pot assembly; it also includes support frames symmetrically arranged on both sides of the acid filling pot assembly; the left support frame includes a shell, a support plate, and a control component, the shell is fixed to the left end of the acid filling pot assembly, the upper end of the support plate extends into the shell through the lower end opening of the shell, and the support plate has a receiving hole; the control component includes a vertical plate and an annular belt, the vertical plate is fixed in the receiving hole, the upper and lower ends of the vertical plate are spaced from the upper and lower ends of the receiving hole respectively, the annular belt is slidably fitted around the outer circumference of the vertical plate, the right inner side of the shell is connected to the right side of the outer ring surface of the annular belt via a connecting rod, the shell is provided with a limiting component for limiting the rotation of the annular belt; the left outer side of the shell is provided with a handle.

[0005] Furthermore, a horizontal plate is fixed to the lower left side of the support plate on the support frame on the left; the front and rear ends of the vertical plate are respectively fixedly connected to the front and rear sides of the receiving hole, and the upper and lower ends of the vertical plate are arc-shaped surfaces with protrusions facing away from each other.

[0006] Furthermore, the annular belt is a ring-shaped belt woven from polytetrafluoroethylene fibers, and the inner side of the annular belt slides in contact with the side of the upright plate.

[0007] Furthermore, the handle on the left side includes a connecting plate and a grip bar. The front and rear parts of the left outer side of the outer casing on the left side are both fixed with connecting plates, and the left ends of the two connecting plates are connected to the grip bar.

[0008] Furthermore, the grip is a rectangular box with its lower opening blocked by a bottom plate. The left limiting component includes a movable plate and a cone. A movable plate is provided between the two connecting plates of the left handle. The movable plate has a pull hole. The left end of the movable plate moves through the right part of the grip and extends into the grip. The left end of the movable plate is connected to the left inner surface of the grip via a spring. The right end of the movable plate moves through the left side plate of the outer shell and faces the left side of the left annular band. Cones with their tips pointing to the right are evenly distributed on the right end face of the movable plate. Multiple cones extend into or out of the left side of the annular band.

[0009] Furthermore, when the multiple cones on the right end of the movable plate on the left extend into the left part of the annular belt, the pull hole on the movable plate is located between the grip rod and the outer shell, and the spring connected to the movable plate is in a semi-compressed state; the left side plate of the outer shell on the left is provided with a through hole for the right end of the movable plate to move through, and when the spring connected to the movable plate on the left is compressed to its limit, the multiple cones on the movable plate on the left are located in the through hole.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: When performing acid injection, this invention releases the two limiting members from restricting the annular band on the same side, allowing the acid injection pot assembly to move downwards along the height direction of the support plate. This connects the spout of the acid injection pot assembly to the inlet of the battery. After the two limiting members restrict the annular band on the same side again, the outer shells on both sides are fixed and locked in the height direction of the support plate, and the position of the acid injection pot assembly is stable, allowing for acid injection.

[0011] When no acid injection is being performed, this invention allows the acid injection pot assembly to move upwards along the height of the support plate by releasing the two limiting members that restrict the annular belt on the same side. This causes the spout of the acid injection pot assembly to be higher than the lower end of the support plate. After the annular belt on the same side is restricted again, the outer shells on both sides are fixed and locked in the height direction of the support plate, and the position of the acid injection pot assembly is stable. When this invention is placed on a workbench, it can prevent the spout of the acid injection pot assembly from contacting the workbench surface and avoid contamination of the spout.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 As shown, an acid filling pot for battery formation includes a pot body 1, each pot body 1 having an acid filling hole 16 at the upper end and a spout 15 at the lower end. Multiple pot bodies 1 are connected sequentially from left to right to form an acid filling pot group. It also includes symmetrical support frames arranged on both sides of the acid filling pot group. The left support frame includes a shell 2, a support plate 3, and a control component. The shell 2 is a hollow cuboid with an opening at the lower end. The shell 2 is fixed to the left end of the acid filling pot group. The upper end of the support plate 3 extends into the shell 2 through the lower opening. The support plate 3 has a side-sliding contact with the outer shell. The inner wall of the shell 2 has a rectangular plate, and the support plate 3 has a receiving hole 4, which is a rectangular hole; the control component includes a vertical plate 5 and an annular belt 6. The vertical plate 5 is fixed in the receiving hole 4, and there is a gap between the upper and lower ends of the vertical plate 5 and the upper and lower ends of the receiving hole 4, respectively. The annular belt 6 is slidably fitted around the outer circumference of the vertical plate 5. The right inner side of the shell 2 is connected to the right side of the outer ring surface of the annular belt 6 via a connecting rod 7. The connecting rod 7 is a long strip rod. The shell is provided with a limiting component for limiting the rotation of the annular belt 6; the left outer side of the shell 2 is provided with a handle.

[0015] A horizontal plate 8 is fixed to the lower left side of the support plate 3 on the support frame on the left side; the vertical plate 5 is a rectangular plate, the thickness of the vertical plate 5 is less than the thickness of the receiving hole 4, the front and rear ends of the vertical plate 5 are respectively fixed to the front and rear sides of the receiving hole 4, and the upper and lower ends of the vertical plate 5 are arc-shaped surfaces with protrusions facing away from each other.

[0016] The annular belt 6 is a ring-shaped belt woven from polytetrafluoroethylene fibers. The inner side of the annular belt 6 slides in contact with the side of the upright plate 5. The annular belt 6 made of polytetrafluoroethylene material has the property of being resistant to acid corrosion. During the formation of the battery, if dilute sulfuric acid or other acid liquids are accidentally immersed in the annular belt 6, it can prevent the annular belt 6 from being damaged.

[0017] The handle on the left side includes a connecting plate 9 and a grip bar 10. The connecting plate 9 is fixed to the front and rear parts of the left outer side of the outer casing 2 on the left side. The connecting plate 9 is a rectangular plate, and the left ends of the two connecting plates 9 are connected to the grip bar 10.

[0018] The grip 10 is a rectangular box with its lower opening blocked by a bottom plate. The left limiting component includes a movable plate 11 and a cone 12. The movable plate 11 is located between the two connecting plates 9 of the left handle. The movable plate 11 is a rectangular plate with a pull hole 17 on it. The pull hole is an oblong hole. The left end of the movable plate 11 moves through the right side of the grip 10 and extends into the grip 10. The left end of the movable plate 11 is connected to the left inner surface of the grip 10 via a spring 13. The right end of the movable plate 11 moves through the left side plate of the outer shell 2 and faces the left side of the left annular belt 6. The right end face of the movable plate 11 is evenly distributed with cones 12 pointing to the right. Multiple cones 12 extend into or out of the left side of the annular belt 6.

[0019] When the multiple cones 12 at the right end of the movable plate 11 on the left side extend into the left part of the annular belt 6, the pull hole 17 on the movable plate 11 is located between the grip 10 and the outer shell 2, and the spring 13 connected to the movable plate 11 is in a semi-compressed state; the left side plate of the outer shell 2 on the left side is provided with a through hole 14 for the right end of the movable plate 11 to move through; when the spring 13 connected to the movable plate 11 on the left side is compressed to its limit, the multiple cones 12 on the movable plate 11 on the left side are located in the through hole 14.

[0020] When this invention is used for acid injection, the lower ends of the support plates 3 and the horizontal plates 8 of the two side support frames are supported on the top surface of the battery. At this time, the spouts 15 of each pot 1 are located above the corresponding battery inlet. The operator grips the left handle 10 with their left hand and inserts their fingers into the pull hole 17 of the left movable plate 11, pulling the movable plate 11 to the left until the spring 13 connected to the left movable plate 11 is compressed to its limit. At this time, the cone 12 at the right end of the left movable plate 11 completely disengages from the left annular belt 6. On the left side, similarly, the operator grips the right-side lever 10 with their right hand and pulls the right-side movable plate 11 to its limit, causing the right-side cone 12 to disengage from the right side of the right-side annular belt 6. At this point, both annular belts 6 are released from their limits and can rotate freely around their respective vertical plates 5. Keeping both movable plates 11 in their extended limit position, the operator grips both levers 10 with both hands and applies downward force, causing the two outer shells 2 and the entire acid injection tank assembly to move downward. The two support plates 3 remain stationary because they are supported by the top surface of the battery. The two outer shells 2 are connected to their respective annular belts 6 via connecting rods 7. When the left outer shell 2 moves downward, it causes the right part of the left annular belt 6 to move downward via connecting rod 7, forcing the left annular belt 6 to rotate clockwise around the outer circumference of the left vertical plate 5. Similarly, when the right outer shell 2 moves downward, it causes the left part of the right annular belt 6 to move downward via connecting rod 7, forcing the right annular belt 6 to rotate counterclockwise around the outer circumference of the right vertical plate 5. When the downward movement continues until all spouts 15 are connected to the corresponding battery inlets, the downward movement stops; the two movable plates are then released. 11. The left movable plate 11 returns to the right under the action of the spring 13, and the cone 12 at the right end extends into the left part of the left annular belt 6, and the right end of the movable plate 11 presses against the left part of the annular belt 6; the right movable plate 11 returns to the left, and the cone 12 at the left end extends into the right part of the right annular belt 6, and the left end of the movable plate 11 presses against the right part of the annular belt 6. The two annular belts 6 cannot rotate because they are limited. Thus, the two outer shells 2 are fixed and locked in the height direction of the support plate 3, the position of the acid injection pot assembly is stable, and acid injection operation can be performed. When not in acid injection mode, this invention is designed so that an assistant holds the support plates 3 of the two side support frames in place to prevent movement. Another operator holds the left and right levers 10 with both hands and pulls the two movable plates 11 in opposite directions to their limits, causing the cones 12 on both sides to disengage from their corresponding annular belts 6, releasing the restriction on the annular belts 6, and keeping the two movable plates 11 in their extended limit state. The operator holds the levers 10 with both hands and lifts them upward, causing the two outer shells 2 and the entire acid injection tank assembly to move upward. Since the support plates 3 on both sides are held stationary by the assistant, the upward movement of the left outer shell 2 will cause the right side of the left annular belt 6 to move upward via the connecting rod 7. The movement forces the left annular belt 6 to rotate counterclockwise around the outer circumference of the left vertical plate 5. The upward movement of the right outer shell 2 will drive the left part of the right annular belt 6 to move upward via the connecting rod 7, forcing the right annular belt 6 to rotate clockwise around the outer circumference of the right vertical plate 5. When the acid injection pot assembly is lifted until all the spouts 15 are higher than the lower end of the support plate 3, the lifting action stops, and the two movable plates 11 are released. The two movable plates 11 automatically reset under the action of their respective springs 13. The cones 12 on the movable plates 11 re-extend and limit the corresponding annular belts 6. The two annular belts 6 are limited, the height of the outer shell 2 is fixed, and the acid injection pot assembly is supported on the workbench by the two support frames. The spouts 15 are suspended and will not contact the workbench.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
