Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a power battery core sampling device. Background Technology

[0002] In existing power battery dismantling operations, the battery cell extraction step typically involves using complex equipment to clamp and remove the cell along with its coating. Subsequent processing steps then rely on manual or semi-automatic equipment to handle the coating. The need for complex and precise mechanical structures to ensure the synchronous removal of the cell and coating not only increases equipment procurement costs but also raises daily maintenance costs. The complex design also makes equipment operation and training more difficult, further increasing operating costs.

[0003] Therefore, the inventors designed a power battery core extraction device to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the present invention provides a power battery core extraction device, which aims to solve the problems of complex equipment, high cost and difficult operation in the core extraction step of power battery dismantling operations in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a power battery core extraction device for extracting and recycling battery cells from a battery casing, comprising a battery cell pulling assembly and a casing clamping assembly. The battery cell pulling assembly includes: an outer pulling frame; an outer pulling motor and an outer pulling screw disposed on the outer pulling frame, the outer pulling motor being connected to one end of the outer pulling screw via belt drive; an outer pulling internal thread block slidably fitted within an outer pulling sliding strip opening disposed on the upper end face of the outer pulling frame, the threaded portion of the outer pulling internal thread block passing through the outer pulling sliding strip opening and threadedly connected to the outer pulling screw; two outer pulling air clamps disposed on the outer pulling internal thread block; two battery cell film cutters symmetrically disposed on both sides of the outer pulling frame, the two battery cell film cutters being located at one end closer to the casing clamping assembly; and a grating sensor disposed on the core extraction placement plate of the casing clamping assembly on one side near the two battery cell film cutters.

[0006] Based on the above, the beneficial effects of a power battery core extraction device are that it solves the problems of complex equipment, high cost, and difficult operation in the core extraction process of power battery dismantling operations in the prior art; mainly reflected in:

[0007] 1. This utility model achieves the separation of battery cell and coating film through a battery cell film cutter, replacing the traditional process of directly removing the battery cell and then processing the coating film manually or with this automatic equipment, thus reducing equipment manufacturing and procurement costs.

[0008] 2. This utility model uses a grating sensor on the core placement plate of the outer casing clamping assembly to monitor whether the battery cell has been completely removed from the battery casing by the battery cell pull-out assembly, thus ensuring the safety performance of the equipment during operation and effectively preventing accidents.

[0009] Furthermore, the outer shell clamping assembly also includes a single-sided positioning plate disposed on one side of the core placement plate, a movable clamping plate disposed on the other side of the core placement plate, and a push-clamping cylinder. The output end of the push-clamping cylinder passes through the core placement plate and is connected to the movable clamping plate via a connecting plate, for driving the movable clamping plate to move towards the single-sided positioning plate.

[0010] Based on the above, the single-sided positioning plate provides a fixed reference surface for the battery casing, ensuring that the position of the battery cells is consistent during each core extraction operation, thus improving the accuracy and repeatability of the operation. The movable clamping plate can be adjusted according to battery casings of different sizes, enabling the device to handle power batteries of various specifications, enhancing the versatility and flexibility of the equipment. The push-clamp cylinder automates the clamping process by driving the movable clamping plate, thereby reducing manual intervention, improving work efficiency, and reducing the risk of operational errors caused by human factors.

[0011] Furthermore, after the external air clamp holds the battery cell, the external motor drives the battery cell to pass through the battery cell film cutter to complete the cutting of the coating film on the battery cell.

[0012] Furthermore, the power battery core extraction device also includes a cell recycling conveyor belt, the input end of which is located below the output end of the cell pulling assembly.

[0013] Based on the above, the beneficial effect of the battery cell recycling conveyor belt is to transport battery cells to the battery cell recycling area.

[0014] Furthermore, the connecting plate is slidably fitted to the bottom of the core placement plate via a slide rail.

[0015] Based on the above, the beneficial effect of the connecting plate sliding with the bottom of the core placement plate via the slide rail is to ensure that the movable clamping plate operates smoothly when clamping the power battery.

[0016] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0021] like Figures 1-3 As shown, a power battery core extraction device is used to clamp and recover battery cells 9 from a battery casing 10. It includes a battery cell pulling assembly 1 and a casing clamping assembly 8. The battery cell pulling assembly 1 includes: an outer pulling frame 2; an outer pulling motor 3 and an outer pulling screw 4 disposed on the outer pulling frame 2, the outer pulling motor 3 being connected to one end of the outer pulling screw 4 via belt drive; an outer pulling internal thread block 5 slidably fitted within an outer pulling sliding slot 21 disposed on the upper surface of the outer pulling frame 2, the threaded portion of the outer pulling internal thread block 5 passing through the outer pulling sliding slot 21 and threadedly connected to the outer pulling screw 4; two outer pulling air clamps 6 disposed on the outer pulling internal thread block 5; two battery cell film cutters 7 symmetrically disposed on both sides of the outer pulling frame 2, the two battery cell film cutters 7 being located near one end of the casing clamping assembly 8; and a grating sensor 811 disposed on the core extraction placement plate 81 of the casing clamping assembly 8 near one side of the two battery cell film cutters 7.

[0022] The outer shell clamping assembly 8 further includes a single-sided positioning plate 82 disposed on one side of the core placement plate 81, a movable clamping plate 83 disposed on the other side of the core placement plate 81, and a push-clamping cylinder 84. The output end of the push-clamping cylinder 84 is connected to the movable clamping plate 83 through the core placement plate 81 via a connecting plate 841, and is used to drive the movable clamping plate 83 to move towards the single-sided positioning plate 82.

[0023] After the external air clamp 6 clamps the battery cell 9, the external motor 3 drives the battery cell 9 to pass through the battery cell film cutter 7 to complete the cutting of the coating film on the battery cell 9.

[0024] The power battery core extraction device also includes a cell recycling conveyor belt 11, the input end of which is located below the output end of the cell pulling assembly 1.

[0025] The connecting plate 841 is slidably fitted to the bottom of the core placement plate 81 via a slide rail.

[0026] In summary, the specific embodiments of this utility model are as follows:

[0027] First, the battery casing 10 is placed on the core placement plate 81 of the casing clamping assembly 8. At this time, the single-sided positioning plate 82 provides a fixed reference surface for the battery casing 10, ensuring the positional consistency of the battery cell 9. Then, the push clamping cylinder 84 pushes the movable clamping plate 83 to move towards the single-sided positioning plate 82 through the connecting plate 841 via the core placement plate 81, so as to adapt to battery casings 10 of different sizes and fix them firmly.

[0028] Subsequently, the external pull motor 3 starts to operate, driving the external pull screw 4 to rotate via belt drive. The external pull internal thread block 5 located on the external pull frame 2 is threadedly connected to the external pull screw 4 and slides within the external pull sliding bar opening 21. As the external pull screw 4 rotates, the external pull internal thread block 5 drives the two external pull air clips 6 to approach the battery cell 9 along the external pull sliding bar opening 21. When the external pull air clips 6 reach the appropriate position, they firmly clamp the battery cell 9.

[0029] Once the battery cell 9 is clamped, the external pull motor 3 reverses its direction, causing the external pull internal thread block 5 to retract along with the battery cell 9. During this process, the battery cell 9 passes through two battery cell film cutters 7 symmetrically arranged on both sides of the external pull frame 2. The two battery cell film cutters 7 cut both sides of the coating film on the battery cell 9, achieving separation of the battery cell 9 from the coating film. The grating sensor 811 monitors the entire process to confirm whether the battery cell 9 has been completely removed from the battery casing 10, thereby sending a signal to the external conveying device to clamp the battery casing 110 for recycling, ensuring the safety and accuracy of the operation.

[0030] Finally, the cut and separated battery cell 9 is pulled out of the battery casing 10 as the external pull clamp 6 continues to move, and eventually falls into the input end of the battery cell recycling conveyor belt 11 located below the battery cell external pull assembly 1. The battery cell recycling conveyor belt 11 transports the processed battery cell 9 to the designated battery cell recycling area, completing the entire battery cell retrieval process.

[0031] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
