[0006] To achieve the above objectives, the present invention adopts the following technical solution: a battery liquid filling device, comprising an operating table and a filling injection head, wherein the filling injection head is disposed above the operating table, and an mounting plate is fixedly installed at the top of the operating table below the filling injection head. A support plate is fixedly installed at the top of the mounting plate. A battery body is disposed between the support plate and the mounting plate near the left inner wall of the support plate. A clamping mechanism is disposed at the top of the mounting plate inside the support plate. The clamping mechanism includes a clamping component and a limiting component. The clamping component includes a support rod and a clamping frame. The upper front and rear surfaces of multiple sets of support rods are slidably connected with sliding rods. A guide plate is fixedly connected to the bottom end of the clamping frame. A moving groove is formed in the middle of the middle support rod.

[0007] As a further description of the above technical solution:

[0008] A reset assembly is provided between the support rod and the clamping frame in the middle. The reset assembly includes a second spring, which is sleeved on the outer wall of the slide rod between the clamping frame and the support rod. One end of the second spring is fixedly connected to the front surface of the clamping frame, and the other end of the second spring is fixedly connected to the rear surface of the support rod.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting plate, and a connecting rod is fixedly connected to the rear surface of the limiting plate. The connecting rod is rotatably connected to the middle of the mounting plate, located below the battery body.

[0011] As a further description of the above technical solution:

[0012] The support rods are provided in multiple sets, and the multiple sets of support rods are evenly and fixedly connected to the front surface of the mounting plate in front of the battery body.

[0013] As a further description of the above technical solution:

[0014] Three sets of sliding rods are evenly arranged and fixedly connected to the front surface of the clamping frame. The clamping frame is U-shaped. The top of the rear surface of the guide block is set as an inclined surface. The inclined surface of the guide block is located below the guide plate.

A locking block is fixedly connected to the inclined surface of the bottom left side of the limiting plate, and the locking block is set at the top of the positioning block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the limiting plate, the connecting rod and another set of limiting plates rotate synchronously. The two sets of limiting plates squeeze the guide rod, causing the guide block to move upward so that its inclined surface squeezes the guide plate, so that the two sets of guide plates and the two sets of clamping frames move inward synchronously until they contact and fix the battery body. At this time, the limiting plate is in a vertical state, supporting and limiting the guide rod in the limiting groove, ensuring that the battery body is stably fixed.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a battery liquid filling device, including an operating platform 1 for processing and operation and a filling injection head 4 for filling the battery with liquid. The filling injection head 4 injects liquid into the battery body 41. The filling injection head 4 is located above the operating platform 1. The top of the operating platform 1 is fixedly installed below the filling injection head 4 and a mounting plate 2 for supporting the battery body 41 is fixedly installed. The top of the mounting plate 2 is fixedly installed with a support plate 42 that cooperates with the mounting plate 2 to support the battery body 41. The battery body 41 is arranged between the support plate 42 and the mounting plate 2 near the left inner wall of the support plate 42. The top of the mounting plate 2 is located inside the support plate 42 and a clamping mechanism for fixing the battery body 41 is arranged inside the support plate 42.

[0032] Furthermore, the clamping mechanism includes a clamping assembly and a limiting assembly. The clamping assembly includes a support rod 24 that provides support and a clamping frame 22 that fits against the outer wall of the battery body 41 and fixes it thereto. The upper front and rear surfaces of the multiple sets of support rods 24 are slidably connected to multiple sets of sliding rods 3 that support the clamping frame 22. The bottom end of the clamping frame 22 is fixedly connected to a guide plate 23 that drives the clamping frame 22 to move. The middle of the support rod 24 located in the middle is slidably connected to a moving groove that provides space for the guide block 27 to move. The inner wall of the moving groove is slidably connected to a guide block 27 that pushes the guide plate 23 to move inward by moving upward on an inclined surface. The inward movement of the guide plate 23 can drive the clamping frame 22 to move inward synchronously and fix the battery body 41. The front surface of the guide block 27 is fixedly connected to a guide rod 25 that limits the guide block 27.

[0033] Reference Figure 1 and Figure 4A reset assembly is provided between the support rod 24 in the middle and the clamping frame 22. The reset assembly includes a spring 31 that can quickly reset the clamping frame 22 by the elastic force of the spring 31. The spring 31 is sleeved on the outer wall of the slide rod 3 between the clamping frame 22 and the support rod 24. One end of the spring 31 is fixedly connected to the front surface of the clamping frame 22, and the other end of the spring 31 is fixedly connected to the rear surface of the support rod 24.

[0034] Reference Figure 2 , Figure 3 and Figure 4 The limiting assembly includes a limiting plate 21 that drives the limiting groove 26 to move. A rotating rod is fixed on the front surface of the limiting plate 21 to facilitate the rotation of the limiting plate 21. A connecting rod 28 is fixedly connected to the rear surface of the limiting plate 21 to connect the front and rear limiting plates 21 simultaneously and operate synchronously. The connecting rod 28 is rotatably connected to the middle of the mounting plate 2, located below the battery body 41. The upper and lower ends of the left side of the limiting plate 21 are both set as inclined surfaces, which can push the guide rod 25 to move upward.

[0035] Furthermore, a limiting groove 26 adapted to the guide rod 25 is provided in the middle of the left side of the limiting plate 21. The limiting groove 26 can limit the guide rod 25, preventing it from automatically moving downward to reset. The top of the guide block 27 is elastically connected to the support rod 24 through a spring 29. One end of the spring 29 is fixedly connected to the top of the guide block 27, and the other end of the spring 29 is fixedly connected to the inner wall of the support rod 24 below the slide rod 3. The other end of the front surface of the support rod 24 on the left side, away from the slide rod 3, is fixedly connected to a positioning block 210 that supports the locking block and the limiting plate 21. The left bottom slope of the limiting plate 21 is fixedly connected to a locking block that cooperates with the positioning block 210 to support the limiting plate 21. The locking block is set at the top of the positioning block 210.

[0036] Reference Figure 2 , Figure 3 and Figure 4 Multiple sets of support rods 24 are provided, and the multiple sets of support rods 24 are evenly and fixedly connected to the front surface of the mounting plate 2, located in front of the battery body 41. Every three sets of sliding rods 3 are evenly arranged and fixedly connected to the front surface of the clamping frame 22. The multiple sets of sliding rods 3 can stably support the clamping frame 22, allowing it to move back and forth stably. The clamping frame 22 is set in a U-shaped frame shape, which can fit against the outer wall of the battery body 41 and fix it stably. The top of the rear surface of the guide block 27 is set as an inclined surface. By setting it as an inclined surface, the guide plate 23 can be squeezed and moved inward. The inclined surface of the guide block 27 is located below the guide plate 23. The guide rod 25 passes through the support rod 24 and slides vertically and is connected to the front surface of the support rod 24. Multiple sets of clamping mechanisms are provided, located on the front and rear sides of the mounting plate 2 and arranged left and right respectively.

[0037] Working principle: During use, the battery body 41 to be filled is placed between the mounting plate 2 and the support plate 42, above the support plate 42. At this time, the clamping frame 22 is not clamped and has a certain distance from the battery body 41. Then, the limiting plate 21 is rotated, which drives the connecting rod 28 to rotate accordingly. At the same time, the other set of limiting plates 21 rotate synchronously. During the rotation, the inclined surfaces at the upper and lower ends of the left side of the limiting plate 21 contact the guide rod 25, pushing the guide rod 25 to move upward. The guide rod 25 compresses the spring 29 at its top. At the same time, when the guide rod 25 moves upward, it drives the fixed connecting rod 28 to rotate. The guide block 27 slides upward in the moving groove in the middle of the support rod 24. The inclined surface at the top of the rear surface of the guide block 27 moves upward and presses the bottom end of the guide plate 23. Under the action of the pressing force, the guide plate 23 drives the clamping frame 22 to move inward along the slide rod 3. At the same time, the clamping frame 22 moves inward and stretches the second spring 31. Since multiple sets of slide rods 3 are evenly arranged on the front surface of the clamping frame 22 and pass through the support rod 24, they provide stable support for the clamping frame 22, so that the front and rear clamping frames 22 of the battery body 41 can move inward synchronously until they are attached to the outer wall of the battery body 41 and are stably fixed.

[0038] Furthermore, when the guide rod 25 rises to a certain height and the limiting plate 21 is in a vertical state, the guide rod 25 is aligned with the limiting groove 26 in the middle of the left side of the limiting plate 21. Under the partial elastic force of the spring 29, the guide rod 25 resets a certain distance and is inserted into the limiting groove 26. The limiting groove 26 limits the guide rod 25, preventing it from moving downwards. At this time, the battery body 41 can be stably fixed, ensuring that the battery body 41 will not be displaced during the filling process. The operation is convenient and quick, and the operation is labor-saving. After the battery body 41 is fixed, the filling injection head 4 located above the operating table 1 descends and injects the liquid into the battery body 41, completing the filling operation.

[0039] After filling is completed, the limiting plate 21 is rotated in the reverse direction, causing the guide rod 25 to disengage from the limiting groove 26. At this time, under the elastic force of the first spring 29, the guide block 27 drives the guide rod 25 to move downward and reset. The guide plate 23 and the clamping frame 22 are no longer subjected to the squeezing force of the inclined surface of the guide block 27. At the same time, the second spring 31 between the clamping frame 22 and the support rod 24 was stretched during the previous clamping process. At this time, the second spring 31 contracts, and the elastic force generated pushes the clamping frame 22 and the slide rod 3 to move outward and quickly reset to the initial position. After the limiting plate 21 rotates to the initial position, the locking block on the inclined surface of the left bottom end of the limiting plate 21 stops on the positioning block 210 on the front surface of the left support rod 24. The positioning block 210 supports the limiting plate 21, so that the filled battery body 41 can be easily removed for subsequent operations, further improving the processing efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
