Description

Technical Field

[0001] This utility model relates to the technical field of battery cell housing processing equipment, specifically to an automatic stacking and storage device for battery cell housings. Background Technology

[0002] The battery cell casing is the aluminum alloy shell of the battery, which is a hollow cuboid. During the production process, the openings at both ends of the battery cell casing need to be rotary cut to make the battery cell casing reach the required length. Then, the cut openings of the battery cell casing are widened and shaped to meet the production standards. Finally, the qualified battery cell casings are removed from the cutting equipment and stored.

[0003] Existing methods for unloading and storing battery cell casings are mostly manual. Workers remove the casings from the unloading station, stack them neatly, and store them in a storage bin. This method requires workers to be present at the unloading station at all times, which is not only a waste of manpower but also inefficient, severely restricting the production efficiency of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a device that can automatically stack and store battery cell housings to improve production efficiency.

[0005] The technical solution of this utility model is to provide an automatic stacking and storage device for battery cell housings with the following structure: The device includes a support frame and a storage assembly and a top assembly mounted on the support frame. The storage assembly includes two symmetrically arranged storage plates. Each storage plate has a slot extending along its height and penetrating its upper and lower ends on one side wall facing each other. A space is formed between the two slots to accommodate stacked battery cell housings. The lower end of each storage plate has a radially extending through-slot. A stop-fall assembly is connected within the through-slot, and the supporting end of the stop-fall assembly can extend or retract from the through-slot. The top assembly is used to push the battery cell housing upwards into the space of the storage assembly. The stop-fall assembly supports the bottom of the lowest battery cell housing within the space to prevent it from falling back.

[0006] With the above structure, the automatic stacking and storage device for battery cell housings in this utility model has the following advantages compared with the prior art: This invention uses a top-feeding component to push the battery cell housings on the unloading station upwards into the storage space of the storage component. Then the top-feeding component resets, and at this time, the anti-fall component supports the bottom of the lowest battery cell housing in the storage space to prevent the battery cell housing from falling back. By repeating the above operation, the battery cell housings in the storage space will be automatically stacked and stored layer by layer without manual operation, which not only saves time and effort but also has high efficiency.

[0007] Preferably, the anti-falling assembly includes an anti-falling block rotatably connected within the through slot. The end of the anti-falling block furthest from its axis of rotation is the support end, used to support the battery cell housing. When the feeding assembly pushes the battery cell housing from the unloading station upward into the receiving space of the storage assembly, the battery cell housing pushes against the support end of the anti-falling block, causing it to flip upward into the through slot. After the battery cell housing rises above the support end, the support end loses the push from the battery cell housing and, under its own gravity, the support end of the anti-falling block falls back. Then, the feeding assembly resets, and the battery cell housing falls and abuts against the support end, preventing the battery cell housing from falling out of the receiving space.

[0008] Preferably, the top of the stop block on the side away from the support end is provided with a radially extending positioning part, and the storage plate is provided with a positioning block near the top of the channel. The positioning block is used to abut against the upper end of the positioning part, so that the support end is in a horizontal state. When the support end falls back, the positioning part rotates synchronously and abuts against the positioning block. The positioning block plays a limiting role, so that the support end is in a horizontal state at this time, which can better support the battery cell housing.

[0009] Preferably, the inner bottom wall of the through groove is provided with a positioning surface, which is used to abut against the lower end of the positioning part so that the rotation angle of the support end is less than 90 degrees. This can prevent the stop block from rotating too much and causing the support end to be unable to rotate.

[0010] Preferably, the anti-falling component further includes a counterweight block, the supporting end of which has a groove, and the counterweight block is connected within the groove. The counterweight block increases the weight of the supporting end of the anti-falling block, allowing the supporting end to stably fall back under its own weight after the lifting component raises the battery cell housing above the supporting end, preventing it from getting stuck in the through slot.

[0011] Preferably, the lower end of the storage plate has two through slots, which are symmetrically arranged; both through slots are connected to the anti-fall component, so as to more stably support the battery cell housing in the accommodating space.

[0012] Preferably, the top material assembly includes two symmetrically arranged drive units. A support plate is connected to the output end of the drive unit. The drive unit is used to drive the support plate to move vertically upward. The support plate is used to support the bottom of the cell housing and drive the cell housing to rise synchronously.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1-4 As shown, this utility model discloses an automatic stacking and storage device for battery cell housings: including a support 1 and a storage component 2 and a top component 3 disposed on the support 1.

[0021] The storage assembly 2 includes two symmetrically arranged storage plates 21. The two storage plates 21 have slots 22 extending along their height direction and penetrating their upper and lower end faces on one side wall facing each other. A space for accommodating stacked battery cell housings is formed between the two slots 22. The distance between the free ends of the two slots 22 is less than the length of the battery cell housing, which can prevent the battery cell housing from coming out laterally.

[0022] The lower end of the storage plate 21 is provided with a radially extending through groove 211, and a stop-fall component 4 is connected in the through groove 211. The support end 411 of the stop-fall component 4 can extend out or retract into the through groove 211.

[0023] The anti-falling component 4 includes an anti-falling block 41 rotatably connected in the through groove 211. The end of the anti-falling block 41 away from its axis of rotation extends inward to form the aforementioned support end 411, which is used to support the battery cell housing.

[0024] The top of the anti-fall block 41 on the side away from the support end 411 is provided with a radially extending positioning part 412. The storage plate 21 is provided with a positioning block 212 near the top of the through groove 211. The positioning block 212 is used to abut against the upper end of the positioning part 412 so that the support end 411 is in a horizontal state.

[0025] The inner bottom wall of the through groove 211 is provided with a positioning surface 213. The positioning surface 213 is used to abut against the lower end of the positioning part 412 so that the rotation angle of the support end 411 is less than 90 degrees. This can prevent the stop block 41 from rotating too much and causing the support end 411 to be unable to rotate.

[0026] The anti-falling component 4 also includes a counterweight 42. The support end 411 of the anti-falling block 41 is provided with a groove 413. The counterweight 42 is connected in the groove 413 to increase the weight of the support end 411 of the anti-falling block 41. After the top material component 3 lifts the battery cell housing above the support end 411, the support end 411 can stably fall back by its own weight, preventing it from getting stuck in the through groove 211.

[0027] In the initial state, the support end 411 of this utility model is horizontally set. When the top material assembly 3 pushes the battery cell housing on the unloading station upward into the accommodating space of the storage assembly 2, the battery cell housing will push the support end 411 of the stop block 41, causing it to flip upward into the through groove 211. Due to the limitation of the positioning surface 213, its flipping angle is less than 90 degrees. After the battery cell housing rises above the support end 411, the support end 411 loses the push of the battery cell housing. Under the action of its own weight and the weight block 42, the support end 411 of the stop block 41 falls back to the positioning part 412 and abuts against the positioning block 212 (i.e., the initial state). At this time, the support end 411 is in a horizontal state, which can better support the battery cell housing. Then the top material assembly 3 resets, the battery cell housing falls down and abuts against the support end 411, preventing the battery cell housing from falling out of the accommodating space.

[0028] The lower end of the storage plate 21 can be provided with two through slots 211, which are symmetrically arranged on the left and right. Both through slots 211 are connected with anti-fall components 4, which can more stably support the battery cell housing in the accommodating space.

[0029] The aforementioned anti-drop component 4 can also be an elastic pin, which can extend into or retract from the receiving space of the storage component 2; the anti-drop component 4 can also be a protrusion and a spring, with one end of the spring connected to the storage plate 21 and the other end connected to the protrusion, the protrusion can extend into or retract into the through groove 211, and the bottom of the protrusion is also provided with an upwardly inclined slope, so that when the top material component 3 pushes the battery cell housing upward into the receiving space of the storage component 2, it is easier to push the protrusion into the through groove 211.

[0030] The top feeding assembly 3 includes two symmetrically arranged drive units 31 (cylinders). A support plate 32 is connected to the output end of the drive unit 31. The drive unit 31 can drive the support plate 32 to move vertically up and down. When the drive unit 31 drives the support plate 32 to move upward, the support plate 32 will support the bottom of the cell housing and drive the cell housing to rise synchronously.

[0031] This invention automatically pushes the battery cell housings on the unloading station upwards into the accommodating space of the storage component 2 using the top feeding component 3. Then, the top feeding component 3 resets, and at this time, the anti-fall component 4 supports the bottom of the lowest battery cell housing in the accommodating space to prevent the battery cell housing from falling back. Repeating the above operation, the battery cell housings in the accommodating space will be automatically stacked and stored layer by layer without manual operation, which is not only time-saving and labor-saving, but also highly efficient. After the accommodating space is full, all battery cell housings can be taken out from the top of the accommodating space at once.

[0032] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
