Description

Technical Field

[0001] This utility model relates to the field of lithium battery casing processing technology, specifically a lithium battery casing buffer platform. Background Technology

[0002] Cleaning the lithium battery casing is a necessary step in the lithium battery manufacturing process. Typically, finished lithium battery casings are temporarily placed on a device called a buffer platform, and then a robotic arm transports them from the buffer platform to a specialized cleaning unit for further cleaning. For example, utility model patent CN210210332U discloses a lithium battery casing buffer platform equipped with multiple pairs of parallel longitudinal clamping rods. The spacing between each pair of clamping rods can be adjusted according to the size of the rectangular cylindrical lithium battery casings to accommodate the storage needs of various lithium battery casing models.

[0003] However, the lithium battery casing buffer platform described above has certain limitations. The position adjustment of the longitudinal clamping rods requires manually tightening the locking nuts. This means that whenever a different model of lithium battery casing is used, the spacing between each pair of longitudinal clamping rods must be adjusted individually. This process is cumbersome and time-consuming, negatively impacting overall production efficiency. In view of these problems, we propose an improved lithium battery casing buffer platform designed to simplify the adjustment process and improve production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery casing buffer platform to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A lithium battery casing buffer platform includes a support platform with a downwardly recessed groove on the top and a plurality of limiting structures spaced apart in the groove along a first horizontal direction. Each limiting structure includes a fixed plate, a movable plate, and a lead screw. The fixed plate is vertically fixed in the groove, and the movable plate is slidably disposed in the groove along the first horizontal direction and arranged parallel to the fixed plate. The lead screw is rotatably connected to the support platform and threadedly connected to the movable plate of each limiting structure. The fixed plate, the movable plate, and the support platform form a first accommodating space for accommodating a single battery casing.

[0007] Optionally, the support platform includes a base plate, legs, and a square side frame. The side frame is fixedly disposed at the top edge of the base plate, and the side frame and the base plate enclose the groove. The legs are fixedly installed at the bottom of the base plate.

[0008] Optionally, a sliding hole extending along a first horizontal direction is provided on the side wall of the support platform, and sliders are fixedly provided at both ends of the movable plate. The sliders are slidably connected to the sliding hole, and the lead screw is threadedly connected to the slider on the movable plate.

[0009] Optionally, each set of limiting structures further includes at least one pair of limiting plates. The at least one pair of limiting plates includes two plates that are elastically connected to the fixed plate and the movable plate respectively. The two plates have a pushing slope on their opposite sides. The fixed plate and the movable plate are provided with insertion holes for the plates to be inserted. The two plates, the fixed plate and the movable plate enclose a second accommodating space.

[0010] Optionally, each set of limiting structures further includes several pairs of limiting plates, which are spaced apart in the first accommodating space along a second horizontal direction perpendicular to the first horizontal direction.

[0011] Optionally, the plate body is elastically connected to the fixed plate and the movable plate through an elastic connection structure. The elastic connection structure includes a screw, a spring, and a first connecting piece. The first connecting piece is fixedly provided at the positions on the fixed plate and the movable plate for connecting the plate body. A second connecting piece is fixedly provided on the plate body. The screw passes through the second connecting piece and is threadedly connected to the first connecting piece. The spring is sleeved on the outside of the screw, and the two ends of the spring abut against the head of the screw and the plate body, respectively. A limit protrusion is fixedly provided on the screw on the side of the plate body away from the spring.

[0012] Compared with the prior art, this utility model provides a lithium battery casing buffer platform, which has the following features:

[0013] Beneficial effects:

[0014] 1. When processing lithium battery casings of different models, this utility model only requires rotating the lead screw to quickly and synchronously adjust the distance between the movable plate and the fixed plate in each set of limiting structures, thereby uniformly adjusting the size of each first accommodating space to adapt to different models of lithium battery casings. Since the dimensions of all first accommodating spaces can be adjusted synchronously, the entire adjustment process is simpler and faster, thus effectively improving the storage efficiency of lithium battery casings;

[0015] 2. The second accommodating space in this utility model is used to define the position of the lithium battery casing. When the fixed plate and the movable plate approach each other, the two plates of the limiting plate also move closer together, thereby reducing the length and width of the second accommodating space simultaneously. Conversely, when the fixed plate and the movable plate move away from each other, the two plates of the limiting plate also separate, causing the length and width of the second accommodating space to increase simultaneously. This setting allows the size of the second accommodating space to be adjusted synchronously, thereby more effectively fixing the lithium battery casing.

[0016] 3. This utility model defines multiple second accommodating spaces within each first accommodating space by setting multiple pairs of limiting plates within each first accommodating space, thereby increasing the number of lithium battery casings that can be placed within a single first accommodating space.

[0022] 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.

[0023] Example 1:

[0024] like Figure 1As shown, an embodiment of this utility model provides a lithium battery casing buffer platform, which includes a support platform with a downwardly recessed groove 4 at the top and several sets of limiting structures spaced apart in the groove 4 along a first horizontal direction. Each set of limiting structures includes a fixed plate 1, a movable plate 2, and a lead screw 3. The fixed plate 1 is vertically fixed in the groove 4, and the movable plate 2 is slidably disposed in the groove 4 along the first horizontal direction and arranged parallel to the fixed plate 1. The first horizontal direction is... Figure 1 In the front-back direction, the lead screw 3 is rotatably connected to the support platform via the bearing 19 and threadedly connected to the movable plates 2 of each set of limiting structures. The fixed plate 1, the movable plate 2 and the support platform form a first accommodating space 5 for accommodating a single battery casing. It can be understood that the size of the first accommodating space 5 should be adapted to the shape of the lithium battery casing, and the depth of the first accommodating space 5 should be less than the height of the lithium battery casing. That is to say, when the lithium battery is placed in the first accommodating space 5, at least a part of the lithium battery will protrude from the first accommodating space 5. In this way, not only can the lithium battery casing be more stably confined in the first accommodating space 5, but it also facilitates the subsequent gripping of the lithium battery casing by the robotic arm.

[0025] With the lithium battery casing buffer platform using the above structure, when different models of lithium battery casings need to be placed, simply rotating the lead screw 3 can quickly and synchronously adjust the distance between the movable plate 2 and the fixed plate 1 in each set of limiting structures, thereby synchronously adjusting the size of each first accommodating space 5. This allows the first accommodating space 5 to be suitable for different models of lithium battery casings. Since the size of each first accommodating space 5 can be adjusted synchronously, the adjustment is more convenient and faster, which helps to improve the storage efficiency of lithium battery casings.

[0026] In this exemplary embodiment, the support platform includes a base plate 7, legs 8, and a square side frame 9. The side frame 9 is fixedly disposed at the top edge of the base plate 7, and the side frame 9 and the base plate 7 enclose the aforementioned groove 4. The legs 8 are fixedly installed at the bottom of the base plate 7. In other embodiments, the side frame 9 and the base plate 7 may also be an integral unit, for example, the aforementioned groove 4 may be formed by slotting the top of a single plate.

[0027] To enable the movable plate 2 to slide slidably within the groove 4 along the first horizontal direction, in this exemplary embodiment, a sliding hole 10 extending along the first horizontal direction is provided on the side wall of the support platform. Slider blocks 11 are fixedly provided at both ends of the movable plate 2, and the sliders 11 are slidably connected to the sliding holes 10. A lead screw 3 is threadedly connected to the sliders 11 on the movable plate 2. Specifically, the lead screw 3 is located outside the groove 4, and the slider 11 passes through the sliding hole 10 and connects to the lead screw 3. When the lead screw 3 is turned, the slider 11 slides within the sliding hole 10.

[0028] Example 2:

[0029] like Figures 2 to 4As shown, based on Embodiment 1, each set of limiting structures further includes at least one pair of limiting plates. Each pair of limiting plates includes two plates 12 elastically connected to the fixed plate 1 and the movable plate 2, respectively. The opposite sides of each plate 12 are provided with a pushing slope 14. The fixed plate 1 and the movable plate 2 are each provided with an insertion hole 13 for the plate 12 to be inserted. The two plates 12, the fixed plate 1, and the movable plate 2 enclose a second accommodating space 6. In this example, the second accommodating space 6 can be used to limit the position of the lithium battery casing. When the fixed plate 1 and the movable plate 2 approach each other, the two plates 12 of the limiting plates approach each other, and the length and width of the second accommodating space 6 decrease simultaneously. Conversely, when the fixed plate 1 and the movable plate 2 move away from each other, the two plates 12 of the limiting plates also move away from each other, and the length and width of the second accommodating space 6 increase simultaneously. This allows the length and width of the second accommodating space 6 to be adjusted synchronously, thereby better limiting the lithium battery casing.

[0030] In this exemplary embodiment, each set of limiting structures further includes several pairs of limiting plates, which are spaced apart within the first accommodating space 5 along a second horizontal direction perpendicular to the first horizontal direction. Figure 2 The left and right directions. By setting multiple pairs of limiting plates in each first accommodating space 5, multiple second accommodating spaces 6 are defined within the first accommodating space 5, thereby increasing the number of lithium battery casings that can be placed in a single first accommodating space 5.

[0031] In this exemplary embodiment, the plate 12 is elastically connected to the fixed plate 1 and the movable plate 2 via an elastic connection structure. The elastic connection structure includes a screw 15, a spring 16, and a first connecting piece 17. The first connecting piece 17 is fixedly provided at the positions on both the fixed plate 1 and the movable plate 2 for connecting the plate 12. A second connecting piece 20 is fixedly provided on the plate 12. The screw 15 passes through the second connecting piece 20 and is threadedly connected to the first connecting piece 17. The spring 16 is sleeved on the outside of the screw 15, and both ends of the spring 16 abut against the head of the screw 15 and the plate 12, respectively. A limit protrusion 18 is fixedly provided on the screw 15 on the side of the plate 12 away from the spring 16. The screw 15 provides guidance for the sliding of the plate 12 along the second horizontal direction, and the spring 16 provides elastic support for the resetting of the plate 12. This ensures the stable movement of the two plates 12 between the fixed plate 1 and the movable plate 2.

[0032] Working principle: When it is necessary to temporarily store completed lithium battery casings, the size of the first accommodating space 5 can be adjusted according to the specific model of the lithium battery casing. Specifically, by rotating the lead screw 3, the movable plates 2 in each set of limiting structures are moved relative to the fixed plate 1, causing them to move closer or further apart, thereby synchronously adjusting the size of the first accommodating space 5 to ensure it fits the currently produced lithium battery casing. Since the size of all the first accommodating spaces 5 can be adjusted uniformly, this makes the adjustment process more convenient and efficient, effectively improving the storage efficiency of the lithium battery casings.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
