Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a cutting device. Background Art

[0002] In the process of battery cell manufacturing, electrode cutting is a crucial link. The dimensional accuracy and shape of the electrode after cutting have a significant impact on the performance parameters of the battery cell, such as energy density, internal resistance and cycle life.

[0003] In traditional battery cell processing, electrode cutting mainly relies on mechanical cutting equipment, which includes a frame with a cutter installed on it. The electrode is transported to the cutting position and can be cut by the cutter.

[0004] However, in order to ensure cutting stability, the cutter of the cutting equipment usually adopts a fixed setting method, and the position of the cutter cannot be adjusted as the size of the electrode changes. As a result, the cutting process needs to rely on the operator's experience to determine whether the cutting position of the electrode corresponds to the cutter, resulting in large size deviations and shapes that do not meet the requirements during the cutting process. This not only affects the performance of the battery cell, but also increases the difficulty and cost of subsequent processes. Utility Model Content

[0066] The utility model embodiment discloses a cutting device.

[0067] Reference Figure 1 and Figure 2The cutting device comprises a cutting frame 1 and a plurality of conveying components 2. The plurality of conveying components 2 are arranged at intervals on the cutting frame 1 for conveying products, and a cutting mechanism is arranged between two adjacent conveying components 2. The cutting mechanism is used for cutting products, and at least one cutting mechanism can move along the conveying direction of the product to adjust the spacing between the plurality of cutting mechanisms.

[0068] Specifically, the cutting frame 1 can be set on the corresponding mechanism, and multiple groups of conveying components 2 are distributed at intervals along the conveying direction of the product on the cutting frame 1. The multiple groups of conveying components 2 can be fixed to each other, or can be selectively moved relative to each other to adjust the spacing between two adjacent conveying components 2. The conveying component 2 can use a structure such as a manipulator to realize the conveying of the product, or it can use a structure such as a roller to realize the conveying of the product. A group of cutting mechanisms is set between two adjacent groups of conveying components 2. The cutting mechanism has a cutting gap for the product to pass through. When the cutting position of the product corresponds to the cutting gap, the cutting mechanism can cut the product. At least one group of cutting mechanisms can move, that is, only one group of cutting mechanisms can move, in which case only one group of moving modules needs to be set to drive the cutting mechanism to move, or multiple groups of cutting mechanisms can all move. Specifically, it can be designed according to the complexity of the driving module that needs to be set when the actual cutting mechanism moves and the overall manufacturing cost. The number of cutting mechanisms and conveying components 2 can be designed according to the requirements of the actual cutting operation. In this embodiment, three groups of conveying components 2 are set, and two groups of cutting mechanisms are set.

[0069] By setting a cutting mechanism between two adjacent groups of conveying components 2, the product can be smoothly conveyed to the cutting mechanism, and at least one group of cutting mechanisms can be moved, so that the spacing between the two adjacent groups of cutting mechanisms can be changed according to the requirements of product size and shape, so that when the product is conveyed by the conveying component 2, it is ensured that each cutting position on the product can correspond to a group of cutting mechanisms. In this way, when the cutting device is used, by adjusting the spacing of the cutting mechanisms, it can be used to cut products of different sizes and shapes to ensure that the products meet the operating requirements after cutting, and when the product is a pole piece, it can also ensure that it does not affect the performance of the battery cell, effectively reducing the difficulty and cost of subsequent processes.

A slide rail is arranged on the cutting frame 1, and the extension direction of the slide rail is consistent with the conveying direction of the product. A slider is slidably connected on the slide rail, and the slider is fixedly connected to the second cutting mechanism 4. The second cutting mechanism 4 extends in a direction perpendicular to the conveying direction of the product. In order to ensure the stable sliding of the second cutting mechanism 4, multiple groups of slide rails and sliders can be distributed at intervals along the extension direction of the second cutting mechanism 4. The adjustment drive member 5 can be a motor, which is fixed on the cutting frame 1. The output end of the motor is fixedly connected with a lead screw 51, and a drive unit 52 is threadedly connected to the lead screw 51. The drive unit 52 is fixedly connected to the second cutting mechanism 4. The motor drives the lead screw 51 to rotate, which can drive the drive unit 52 to move, and the drive unit 52 then drives the second cutting mechanism 4 to move, so as to adjust the position of the second cutting mechanism 4. It should be understood that the lead screw 51 can also be directly threadedly connected to the second cutting mechanism 4, or the drive member 5 can be a cylinder connected to the second cutting mechanism 4. The structure of the specific adjustment drive member 5 can be designed according to the actual installation space and the distance that the second cutting mechanism 4 needs to move, and the utility model does not limit this. The specific number of the first cutting mechanism 3 and the second cutting mechanism 4 can be designed according to the actual cutting requirements. In this embodiment, only one set of the first cutting mechanism 3 and the second cutting mechanism 4 is provided, and only one adjustment drive member 5 is provided.

[0072] When the relative position between the first cutting mechanism 3 and the second cutting mechanism 4 needs to be adjusted, the adjusting driving member 5 is driven to drive the second cutting mechanism 4 to slide, thereby changing the position of the second cutting mechanism 4 relative to the first cutting mechanism 3, thereby changing the distance between the first cutting mechanism 3 and the second cutting mechanism 4 to meet the cutting requirements of products of different sizes and shapes.

[0073] Optionally, the cutting frame 1 includes a first cutting board 11 and a second cutting board 12. At least one group of cutting mechanisms is arranged on the first cutting board 11, and the remaining cutting mechanisms are arranged on the second cutting board 12; the cutting device also includes a frame 6 and a first driving assembly 7. The first cutting board 11 and the second cutting board 12 are both arranged on the frame 6, and the first cutting board 11 is slidably connected to the cutting frame 1 along the conveying direction of the product; the first driving assembly 7 is arranged on the frame 6 and connected to the first cutting board 11 to adjust the distance between the first cutting board 11 and the second cutting board 12.

[0074] Specifically, the first cutting board 11 and the second cutting board 12 are distributed along the conveying direction of the product, and the first cutting board 11 is slidably connected to the bottom plate 61 of the frame 6 through the slide rail and the slider, and an installation space is formed between the first cutting board 11 and the bottom plate 61. The first driving component 7 is arranged in the installation space and connected to the first cutting board 11 to drive the first cutting board 11 to move along the conveying direction of the product. The first driving component 7 can be formed by a hand-cranked screw, or by a motor screw or other structure, which can smoothly drive the first cutting board 11 to move.

[0075] In this embodiment, the first cutting mechanism 3 in the plurality of cutting mechanisms is arranged on the first cutting board 11, and the second cutting mechanism 4 is slidably connected to the second cutting board 12. In this way, the first cutting mechanism 3 can adjust the distance between it and the second cutting mechanism 4 by moving the first cutting board 11. In another embodiment, the first cutting mechanism 3 is arranged on the second cutting board 12, and the second cutting mechanism 4 is slidably connected to the first cutting board 11, and in this case, the second cutting mechanism 4 can move in a larger range. In another embodiment, the first cutting mechanism 3 and the second cutting mechanism 4 are fixed on the first cutting board 11 and the second cutting board 12 respectively, and in this case, the first cutting mechanism 3 and the second cutting mechanism 4 only rely on the movement of the first cutting board 11 to achieve the change of the distance.

[0076] When adjusting the relative positions of the first cutting mechanism 3 and the second cutting mechanism 4, the first driving assembly 7 can be used to drive the first cutting plate 11 to move, thereby driving the cutting mechanism arranged on the first cutting plate 11 to move relative to the frame 6, while the second cutting plate 12 remains stationary, thereby smoothly realizing the adjustment of the distance between the first cutting mechanism 3 and the second cutting mechanism 4.

The top wall of the driving block 72 is fixedly connected to the bottom wall of the first cutting plate 11, and the fixed connection method can be welding, screw connection, etc.

[0079] When the first cutting board 11 needs to be driven to move, the operator grasps and screws the handle 73 to drive the driving rod 71 to rotate. As the driving rod 71 rotates, the driving block 72 can be driven to move along the conveying direction of the product. When the driving block 72 moves, it can smoothly pull the first cutting board 11 to move.

The locking member can also be an insert block, and the insert block has a fixing rod that can be inserted into the fixing hole 62, and the insert block can fill the locking hole 81, so that the locking hole 81 and the frame 6 can be locked.

[0082] By providing the locking block 8, the first cutting board 11 can be locked on the frame 6. When the position of the first cutting board 11 needs to be adjusted, the locking piece is taken out from the locking hole 81 to unlock the locking block 8. By providing a plurality of fixing holes 62, the first cutting board 11 can be locked at any position by installing the locking piece.

[0088] When cutting the product, the cutting drive 33 is started, and the cutting drive 33 drives the cutting knife 32 to slide up and down through the cam transmission structure 34. When the product is between the cutting strip 31 and the cutting knife 32, the cutting knife 32 is inserted into the cutting slit to complete the cutting. The specific sliding distance of the cutting knife 32 depends on the distance between the cutting knife 32 and the bottom wall of the cutting slit, and it is sufficient to ensure that the cutting knife 32 is inserted into the cutting slit to complete the cutting of the product and can be pulled out of the cutting slit.
