Description

Technical Field

[0001] This utility model relates to a clamp, specifically a battery cell liquid injection clamp. Background Technology

[0002] A battery cell is the energy storage component of a rechargeable battery. It consists of positive and negative electrodes, a separator, electrolyte, and a casing. It is the basic unit of a battery and an important component. A battery cell typically refers to a single electrochemical unit containing positive and negative electrodes. These units store and release electrical energy through chemical reactions. The quality of the battery cell directly determines the performance of the rechargeable battery, including capacity, voltage, cycle life, and safety. A battery cell does not have a protection circuit or casing and needs to be combined with other components (such as a protection circuit board) to form a complete battery. Types of battery cells include aluminum-cased cells, pouch cells, and cylindrical cells. They differ in appearance and structure but all have similar functions. When repairing or maintaining a battery cell, electrolyte needs to be added to the inside of the cell.

[0003] Currently, in existing technologies, the battery may be tilted when adding electrolyte to the cell, and the electrolyte will be uneven when the battery is tilted. Therefore, this application proposes a cell electrolyte injection fixture to solve this problem. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A battery cell liquid injection clamp includes a support plate. Connecting rods are symmetrically arranged on the top of the support plate. Clamping plates are fixedly installed at one end of each connecting rod. A placement frame is fixedly installed on the top of the support plate and below the clamping plates. A second fixing plate is fixedly installed on the front side of the placement frame. A bubble level is fixedly installed on the top of the second fixing plate. The support plate is circular.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a battery cell liquid injection clamp includes a support plate 8. Connecting rods 14 are symmetrically arranged on the top of the support plate 8. Clamping plates 13 are fixedly installed at one end of each of the two connecting rods 14. A placement frame 12 is fixedly installed on the top of the support plate 8 and below the clamping plates 13. A second fixing plate 16 is fixedly installed on the front side of the placement frame 12. A bubble level 15 is fixedly installed on the top of the second fixing plate 16. The support plate 8 is circular in design. Three support components are equidistantly arranged in the circumferential direction at the bottom of the support plate 8. The support components include an internal threaded cylinder 3. An external threaded rod 4 is connected to the internal thread of the internal threaded cylinder 3. One end of the external threaded rod 4 passes through the internal threaded cylinder 3 and is fixedly installed with a support foot 7.

[0022] A first fixing plate 2 is symmetrically fixedly installed on the top of the support plate 8. A fixing block 11 is fixedly installed on the top of the support plate 8 at the middle position. Rods 9 are symmetrically fixedly installed on both sides of the fixing block 11. One end of each of the two rods 9 on both sides of the fixing block 11 is fixedly connected to the first fixing plate 2. Two sliding sleeves 5 are slidably connected to the outer sides of the two rods 9 on both sides of the fixing block 11. A first mounting plate 1 and a second mounting plate 18 are respectively provided above the two rods 9 on both sides of the fixing block 11. The tops of the sliding sleeves 5 on both sides of the fixing block 11 are respectively connected to the first mounting plate 2. Mounting plate 1 and second mounting plate 18 are fixedly connected. An electric push rod 6 is fixedly installed at the bottom of the first mounting plate 1. The push rod end of the electric push rod 6 is fixedly connected to the fixing block 11. A connecting plate 10 is rotatably installed on one side of the top of the first mounting plate 1 and the middle position of the second mounting plate 18. A rotating plate 17 is rotatably installed on the top of the fixing block 11. One end of the two connecting plates 10 is rotatably connected to the front and rear sides of the top of the rotating plate 17, respectively. The first mounting plate 1 and the second mounting plate 18 drive the two clamping plates 13 to move closer to each other, thereby clamping and fixing the battery cell.

[0023] The rotating plate 17 has a diamond-shaped design, which increases the lateral length of the pull.

[0024] The bottom ends of the two connecting rods 14 are fixedly connected to the first mounting plate 1 and the second mounting plate 18, respectively.

[0025] The placement rack 12 is located on the outside of the connecting plate 10.

[0026] A switch is fixedly installed on the support plate 8. The electric push rod 6 is electrically connected to the switch through a wire, and the switch is electrically connected to an external power source through a wire.

[0027] The working principle of this utility model is as follows:

[0028] In use, the battery cell is placed on top of the mounting bracket 12, and then the electric push rod 6 is activated, causing the push cylinder end of the electric push rod 6 to move towards the push rod end. This causes the first mounting plate 1 to move towards the fixed block 18. Since the connecting plate 10 and the first mounting plate 1 are hinged, the first mounting plate 1 will drive the connecting plate 10 to rotate during its movement. During the rotation of the connecting plate 10, the rotating plate 17 will be pulled to rotate on top of the fixed block 18. During the rotation of the rotating plate 17 and the connecting plate 10, the second mounting plate 18 will also move closer to the first mounting plate 1. The connecting rod 14 at the top of the first mounting plate 1 and the second mounting plate 18 will drive the two clamping plates 13 to move towards each other. This involves clamping and fixing the battery cell. After clamping and fixing the battery cell, observe whether the bubble in the bubble level 15 is in the center position. If the bubble is not in the center position, adjust the height of the three support components. The specific adjustment method is to rotate the external thread rod 4 so that the external thread rod 4 extends into the inner thread cylinder 3 or extends outward from the inner thread cylinder 3. However, when extending, the external thread rod 4 needs to be kept a certain distance inside the inner thread cylinder 3 to avoid the device being unstable. When the bubble is facing a certain support component, increase or decrease the height of the other two support components until the bubble is in the center position of the bubble level 15. At this time, the support plate 8 remains horizontal, and normal liquid injection can be performed.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
