Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0046] The following description, with reference to the accompanying drawings, describes a cutting device 100 for processing batteries according to an embodiment of the present invention. For example, the cutting device 100 is a cutting device 100 for cutting aluminum-plastic film air bags for batteries.

[0047] Reference Figures 1-7 As shown, the cutting device 100 for processing batteries according to an embodiment of the present invention may include: a first cutter 21 and a second cutter 31.

[0048] Specifically, the first cutter 21 and the second cutter 31 extend along a first direction, and at least one of the first cutter 21 and the second cutter 31 is movable along a second direction. That is, only the first cutter 21 is movable along the second direction, or only the second cutter 31 is movable along the second direction, or both the first cutter 21 and the second cutter 31 are movable along the second direction. All of these arrangements enable the first cutter 21 and the second cutter 31 to jointly cut the workpiece 200, thereby fulfilling the cutting requirements of the cutting device 100 for the battery. For example, when both the first cutter 21 and the second cutter 31 move along the second direction toward each other, the cutting effect of the first cutter 21 and the second cutter 31 on the workpiece 200 is better, thereby ensuring high processing efficiency of the cutting device 100.

[0049] In addition, such as Figure 2 and Figure 7 As shown, at least the cutting edges of the first cutter 21 and at least the cutting edges of the second cutter 31 are offset along a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other. Therefore, by offsetting the cutting edges of the first cutter 21 and the second cutter 31 when cutting the workpiece 200, the cutting areas of the first cutter 21 and the second cutter 31 do not overlap. This disperses the force exerted by the first cutter 21 and the second cutter 31 on the workpiece 200, allowing the workpiece 200 to be torn apart under the relative forces of the first cutter 21 and the second cutter 31. This ensures that the removed portion 202 of the workpiece 200 is completely cut, avoiding problems such as incomplete removal that easily occur when the first cutter and the second cutter are pressed together when cutting the workpiece in related technologies. This ensures a good cutting effect on the workpiece 200, thereby ensuring that the cutting requirements of the workpiece 200 are met, avoiding the problem of secondary cutting, and improving production efficiency.

[0050] At the same time, it can reduce the difficulty of controlling the processing and assembly accuracy in related technologies to ensure that the first cutter and the second cutter abut against each other, which is conducive to reducing the production cost of the cutting device 100. It can also avoid problems such as collision, wear and vibration caused by the first cutter 21 and the second cutter 31 abutting against each other to cut the workpiece 200, ensuring the working reliability of the cutting device 100 and extending its service life.

[0051] In addition, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, along a third direction, the two sides of the first cutter 21 are a first side 23 and a second side 24, respectively. The second cutter 31 is located on the first side 23 of the first cutter 21. The cutting device 100 includes a limiting structure 32, which extends beyond the cutting edge of the second cutter 31 along a second direction and can abut against the first side 23 of the first cutter 21. Thus, when at least one of the first cutter 21 and the second cutter 31 moves along the second direction, the limiting structure 32 can play an auxiliary positioning role for the first cutter 21, ensuring reliable movement between the first cutter 21 and the second cutter 31, avoiding collisions between the cutting edges of the first cutter 21 and the second cutter 31, and ensuring the processing reliability of the cutting device 100.

[0052] In some embodiments, such as Figure 8 and Figure 9 As shown, the workpiece 200 includes a battery body portion 201 and a cut-out portion 202. The first cutter 21 and the second cutter 31 can jointly cut the workpiece 200, so that the cut-out portion 202 can be removed from the battery body portion 201, thus fulfilling the cutting requirements of the battery. For example, the cut-out portion 202 is an air bag.

[0053] According to the present invention, the cutting device 100 extends along a first direction via a first cutter 21 and a second cutter 31. At least one of the first cutter 21 and the second cutter 31 is movable along a second direction to jointly cut the workpiece 200. The cutting edges of at least the first cutter 21 and at least the second cutter 31 are offset along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other, which ensures that the cut-off portion 202 of the workpiece 200 is completely cut open, ensuring a good cutting effect on the workpiece 200, which is beneficial to improving production efficiency and reducing the difficulty of processing and assembly accuracy, which is beneficial to reducing the production cost of the cutting device 100. At the same time, it avoids problems such as collision, wear, and vibration caused by the first cutter 21 and the second cutter 31 cutting the workpiece 200 together, ensuring the working reliability of the cutting device 100 and extending its service life. In addition, the limiting structure 32 can play an auxiliary positioning role for the first cutter 21, ensuring reliable movement between the first cutter 21 and the second cutter 31, avoiding problems such as collision between the blades of the first cutter 21 and the second cutter 31, and ensuring the processing reliability of the cutting device 100.

[0054] In some embodiments of this utility model, such as Figure 2 and Figure 7 As shown, along the second direction, the first cutter 21 and the second cutter 31 are in an overlapping state. In the overlapping state, the cutting edges of the first cutter 21 and the second cutter 31 are in contact with each other's surfaces, ensuring that the relative position of at least one of the first cutter 21 and the second cutter 31 is reliable when moving, avoiding problems such as misalignment, and enabling the first cutter 21 and the second cutter 31 to cut the workpiece 200 close together, avoiding problems such as force dispersion and easy deformation of the workpiece 200, and ensuring that the cutting device 100 has a good cutting effect on the workpiece 200.

[0055] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the limiting structure 32 is connected to the second cutter 31, which can improve the structural strength of the second cutter 31. The limiting structure 32 has a clearance opening 321, which can avoid the workpiece 200, avoid the risk of collision between the limiting structure 32 and the workpiece 200, and reduce the collision failure rate between the cutting device 100 and the workpiece 200. For example, the collision failure rate between the cutting device 100 and the workpiece 200 can be reduced to 0%, which makes it easier for the workpiece 200 to pass through the cutting device 100, meet the required processing requirements, and can realize automatic avoidance of the workpiece 200, avoiding the problems of operation complexity caused by moving the second cutter 31, which is conducive to improving processing efficiency.

[0056] In some embodiments, such as Figure 2 and Figure 7 As shown, the outer contour of the clearance opening 321 along the cross section perpendicular to the first direction is formed in the shape of "C", which makes the structure of the clearance opening 321 simple, easy to process and manufacture, and ensures that the workpiece 200 can pass through the clearance opening 321 conveniently, effectively avoiding collision and other problems.

[0057] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the second cutter 31 has a limiting structure 32 on at least one side of its two sides along the first direction. This allows the limiting structure 32 to limit the first cutter 21, ensuring reliable limiting of the first cutter 21 and preventing problems such as deviation. This also ensures the reliability of the cutting of the workpiece 200 by the first cutter 21 and the second cutter 31, and reduces the material used in the limiting structure 32, thus saving costs. Furthermore, when the second cutter 31 has a limiting structure 32 on both sides along the first direction, it further ensures the reliable limiting of the first cutter 21 along the first direction.

[0058] In some embodiments of this utility model, such as Figures 1-3 , Figure 6 and Figure 7 As shown, the second direction is the up-down direction, and the first cutter 21 is at least partially located above the second cutter 31. Along the third direction, the clamp 300 for clamping the workpiece 200 is located on the side of the cutting edge of the first cutter 21 away from the cutting edge of the second cutter 31. It can limit the position of the first cutter 21 and the second cutter 31 according to the actual situation, meet different processing requirements, and thus realize the cutting requirements of the workpiece 200.

[0059] In some embodiments, such as Figure 8 and Figure 9 As shown, the workpiece 200 includes a battery body portion 201 and a cut-off portion 202. The clamp 300 clamps the battery body portion 201. The first cutter 21 and the second cutter 31 are both movable along the second direction. The first cutter 21 can abut against the cut-off portion 202. The cut-off portion 202 is mainly driven by the second cutter 31 from bottom to top, causing the cut-off portion 202 to detach from the battery body portion 201, thereby cutting the workpiece 200. Since the second cutter 31 is located on the side of the first cutter 21 away from the battery body portion 201, it can avoid problems such as bending of the end of the battery body portion 201 facing the cut-off portion 202, ensuring that the cutting device 100 has a good cutting effect on the workpiece 200.

[0060] According to some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the cutting device 100 also includes a guide structure 34. Along a third direction, the guide structure 34 is located on the side of the cutting edge of the second cutter 31 facing away from the clamp 300. In the top-to-bottom direction, the surface of the guide structure 34 facing away from the clamp 300 is inclined in the direction away from the clamp 300. Therefore, when the first cutter 21 and the second cutter 31 cut the workpiece 200, the waste generated during cutting (e.g., the removed portion 202) can be easily moved to the desired position by the guide structure 34, facilitating waste collection. Furthermore, the guide structure 34 has a simple structure and is easy to manufacture.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the guide structure 34 and the end face of the second cutter 31 opposite to the clamp 300 are connected, which can improve the structural strength of the second cutter 31 and facilitate the guidance of the waste generated by cutting through the guide structure 34, reduce the waste entering between the second cutter 31 and the guide structure 34, ensure reliable guidance, and facilitate the fixation of the guide structure 34 through the second cutter 31, ensuring a compact structure.

[0062] In some embodiments of the cutting device 100 including the limiting structure 32, such as Figure 1 and Figure 2 As shown, at least one side of the guide structure 34 along the first direction is connected to the limiting structure 32. The guide structure 34 is connected to the end face of the second cutter 31 away from the clamp 300, ensuring that the guide structure 34 and the limiting structure 32 are reliably fixed on the second cutter 31, which can meet the required fixing requirements, improve the structural strength of the second cutter 31, avoid deformation and other problems, and help extend the service life.

[0063] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 6 As shown, the cutting device 100 also includes a waste box 41. Along a third direction, the waste box 41 is located on the side of the blade of the second cutter 31 away from the clamp 300. At least a portion of the waste box 41 is located below the blade of the second cutter 31, so that the waste generated by the cutting by the first cutter 21 and the second cutter 31 can enter the waste box 41 under the action of gravity, which facilitates the collection of waste and the centralized processing of waste, optimizes the production environment and safety of the cutting device 100, and helps to improve the cutting efficiency.

[0064] According to some embodiments of this utility model, such as Figure 1 and Figure 6As shown, the cutting device 100 also includes a guide 42, which is connected to the second cutter 31 and can be fixed. In the third direction, the guide 42 is located on the side of the second cutter 31 away from the clamp 300. The guide 42 is at least partially located above the waste box 41. The guide 42 can guide the waste material after cutting the workpiece 200 into the waste box 41, which is convenient for waste collection. At the same time, the guide 42 ensures reliable guidance of waste material and effectively prevents waste material from scattering and causing the cutting device 100 to jam.

[0065] In some embodiments of this utility model, such as Figure 1 As shown, the guide 42 includes a guide plate 421, which is at least partially located above the waste container 41. Along a third direction, in the direction from the first cutter 21 to the second cutter 31, the guide plate 421 is inclined downwards. The end of the guide plate 421 facing away from the clamp 300 is positioned vertically opposite to the waste container 41. This facilitates the entry of waste into the waste container 41 under the guidance of gravity and the guide plate 421, meeting the required collection needs. Waste collection is convenient, and the guide 42 has a simple structure, making it easy to manufacture and reducing production costs.

[0066] According to some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the guide 42 also includes a protective plate 422. The guide plate 421 has protective plates 422 at opposite ends along the first direction. The protective plates 422 are located above the guide plate 421 and extend along the edge of the protective plate 422, so that the protective plate 422 can block the waste on the guide plate 421, preventing the waste from falling from the edge of the protective plate 422 and causing pollution to the production environment of the cutting device 100, thus ensuring reliable waste collection. At the same time, the guide 42 has a simple structure, is easy to process and manufacture, and helps to reduce production costs.

[0067] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cutting device 100 also includes a guide structure 34. Along the third direction, the guide structure 34 is located between the guide member 42 and the second cutter 31. In the top-to-bottom direction, the surface of the guide structure 34 facing away from the clamp 300 is inclined in the direction facing away from the clamp 300, so that the waste material after the workpiece 200 is cut can enter the waste box 41 in sequence through the guide structure 34 and the guide member 42, realizing the continuity of waste material movement, ensuring reliable guidance of waste material, and meeting the required collection needs.

[0068] In related technologies, waste material from workpiece cutting often remains on the cutting device. For example, debris from the air bag after cutting may remain in the fixture gaps, easily contaminating the workpiece. For instance, the cleanliness exceedance rate in related technologies is greater than 12%.

[0069] Therefore, according to some embodiments of the present invention, the cutting device 100 includes a negative pressure device, which can create a negative pressure inside the waste box 41, so that the waste can enter the waste box 41 under the action of negative pressure, making it easier to collect the waste, thereby avoiding waste residue after cutting, ensuring the cleanliness of the cutting device 100, for example ensuring a cleanliness compliance rate of 100%, thereby avoiding contamination of the workpiece 200, for example meeting the requirements of zero-pollution battery production.

[0070] In some embodiments of this utility model, the waste box 41 is provided with an air extraction port, and the negative pressure device is connected to the air extraction port, which enables the negative pressure device to connect with the waste box 41, making it convenient for the negative pressure device to extract air from the waste box 41, and avoiding problems such as damage caused by placing the negative pressure device directly in the waste box 41, which is beneficial to extending the service life.

[0071] According to some embodiments of this utility model, the air extraction port is located at the bottom of the waste box 41, which facilitates air extraction from the bottom of the waste box 41, ensuring that a reliable negative pressure is formed inside the waste box 41, effectively reducing waste residue on the inner peripheral wall of the waste box 41, and ensuring cleanliness.

[0072] In some embodiments, the air extraction port is located on the side wall of the waste box 41, which can prevent waste from blocking the air extraction port, ensure reliable air extraction, and prevent waste from entering the negative pressure device through the air extraction port, which is beneficial to extending the service life of the negative pressure device.

[0073] In some embodiments of this utility model, the negative pressure device includes an air pump and an air extraction pipe. The two ends of the air extraction pipe are connected to the air pump and the air extraction port, so that the air pump is connected to the waste box 41 through the air extraction pipe. Gas can flow to the air pump through the air extraction pipe, ensuring reliable gas flow and facilitating the formation of negative pressure in the waste box 41. Moreover, the structure of the negative pressure device is simple, which can reduce production costs.

[0074] According to some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 6 As shown, the cutting device 100 also includes a drive assembly 50, which can drive at least one of the first cutter 21 and the second cutter 31 to move along a second direction, so as to facilitate the movement requirements of at least one of the first cutter 21 and the second cutter 31, ensure reliable cutting of the workpiece 200, and realize automation, which helps to reduce manual operation and ensure production efficiency.

[0075] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 6 As shown, the first cutter 21 is movable along the second direction. The drive assembly 50 includes a first drive member 51, which can drive the first cutter 21 to move along the second direction, thereby fulfilling the movement requirements of the first cutter 21, ensuring reliable cutting of the workpiece 200, and enabling automation, which helps to reduce manual operation and ensure production efficiency.

[0076] In the embodiments of this utility model, the specific structure of the first driving member 51 can be set according to the actual situation.

[0077] For example, in some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the first driving component 51 can be a cylinder or a linear motor. The first driving component 51 is connected to the first cutter 21, which can ensure that the first driving component 51 can reliably drive the first cutter 21 to move in the second direction.

[0078] For example, in some embodiments, the first driving member 51 includes a motor and a transmission mechanism, which are connected in a transmission manner. The transmission mechanism is also connected in a transmission manner to the first cutter 21. The motor drives the transmission mechanism to move, which in turn drives the first cutter 21 to move, thus fulfilling the movement requirement of the first cutter 21.

[0079] According to some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 6 As shown, the second cutter 31 is movable along a second direction. The drive assembly 50 includes a second drive member 52, which can drive the second cutter 31 to move along the second direction, thus fulfilling the movement requirements of the second cutter 31, ensuring reliable cutting of the workpiece 200, and enabling automation, which helps reduce manual operation and ensures production efficiency. Simultaneously, when the first drive member 51 can drive the first cutter 21 to move along the second direction and the second drive member 52 can drive the second cutter 31 to move along the second direction, the reliability of the first cutter 21 and the second cutter 31 in cutting the workpiece 200 is ensured, and it is convenient to control the first cutter 21 and the second cutter 31 separately, ensuring reliable control and reducing production costs.

[0080] In the embodiments of this utility model, the specific structure of the second driving member 52 can be set according to the actual situation.

[0081] For example, in some embodiments, such as Figure 1 , Figure 3 and Figure 6As shown, the second drive unit 52 can be a cylinder or a linear motor. The second drive unit 52 is connected to the second cutter 31, which can ensure that the second drive unit 52 can reliably drive the second cutter 31 to move along the second direction.

[0082] For example, in some embodiments, the second drive unit 52 includes a motor and a transmission mechanism, which are connected in a transmission manner. The transmission mechanism is also connected in a transmission manner to the second cutter 31. The motor drives the transmission mechanism to move, which in turn drives the second cutter 31 to move, thus fulfilling the movement requirement of the second cutter 31.

[0083] In some embodiments of this utility model, such as Figure 2 As shown, the cutting device 100 also includes a support body 10. A first cutter 21 is movably disposed on the support body 10 along a second direction. A first guide member 22 is provided on the first cutter 21, extending along the second direction. A first guide portion 11 is provided on the support body 10. Thus, through the cooperation of the first guide portion 11 and the first guide member 22, the first guide portion 11 can guide the first guide member 22, ensuring that the first cutter 21 moves reliably on the support body 10 along the second direction, avoiding problems such as deviation, thereby ensuring the reliability of the cutting device 100 in cutting the workpiece 200.

[0084] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple first guide members 22, which are spaced apart along the length of the first cutter 21. There are multiple first guide parts 11 that correspond one-to-one with the multiple first guide members 22. By cooperating with the multiple first guide parts 11 and the multiple first guide members 22, it is possible to limit the multiple different positions of the first cutter 21, ensure the reliable guidance of the first cutter 21, avoid problems such as deviation, and thus ensure the reliability of the movement of the first cutter 21, so as to make the cutting of the workpiece 200 reliable.

[0085] In embodiments of this utility model, the number of first guide members 22 can be flexibly set according to actual conditions. For example, the number of first guide members 22 can be as follows: Figure 1 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0086] In the embodiments of this utility model, the specific structures of the first guide portion 11 and the first guide member 22 can be set according to the actual situation.

[0087] For example, in some embodiments, such as Figure 2As shown, the first guide portion 11 is a guide rail extending along the second direction, and the first guide member 22 is a slider with a groove 221 extending along the second direction. Thus, by cooperating with the guide rail, the guide rail can limit the slider's movement, ensuring that the slider moves along the length of the guide rail. This ensures reliable movement of the first cutter 21 along the second direction. Furthermore, the structure of the first guide portion 11 and the first guide member 22 is simple, facilitating manufacturing and reducing production costs.

[0088] According to some embodiments of this utility model, such as Figure 5 As shown, the cutting device 100 also includes a support body 10. A second cutter 31 is movably disposed on the support body 10 along a second direction. A second guide member 33 is provided on the second cutter 31, extending along the second direction. A second guide portion 12 is provided on the support body 10. Thus, through the cooperation of the second guide portion 12 and the second guide member 33, the second guide portion 12 can guide the second guide member 33, ensuring that the second cutter 31 moves reliably on the support body 10 along the second direction, avoiding problems such as deviation, thereby ensuring the reliability of the cutting device 100 in cutting the workpiece 200.

[0089] In some embodiments, such as Figure 3 As shown, there are multiple second guide members 33, which are spaced apart along the length of the second cutter 31. There are multiple second guide parts 12 that correspond one-to-one with the multiple second guide members 33. By cooperating with the multiple second guide parts 12 and the multiple second guide members 33, it is possible to limit the multiple different positions of the second cutter 31, ensure the reliable guidance of the second cutter 31, avoid problems such as deviation, and thus ensure the reliability of the movement of the second cutter 31, so that the cutting of the workpiece 200 is reliable.

[0090] In embodiments of this utility model, the number of second guide members 33 can be flexibly set according to actual conditions. For example, the number of second guide members 33 can be as follows: Figure 3 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0091] In the embodiments of this utility model, the specific structures of the second guide portion 12 and the second guide member 33 can be set according to the actual situation.

[0092] For example, in some embodiments, such as Figure 2As shown, the second guide member 33 is a guide post extending along the second direction, and the second guide portion 12 is a guide hole, in which the guide post is movably inserted along the second direction. Thus, by cooperating with the guide post and the guide hole, the second cutter 31 can be guided along the second direction, ensuring reliable movement of the second cutter 31 along the second direction. Furthermore, the second guide portion 12 and the second guide member 33 have simple structures, are easy to manufacture, and help reduce production costs.

[0093] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the cutting device 100 also includes a linear bearing 14, which is inserted into the guide hole and sleeved on the outside of the guide post. This reduces the friction between the guide post and the guide hole, ensures movement stability, and enables low-resistance linear reciprocating movement, which is beneficial to improving movement efficiency and extending service life.

[0094] According to some embodiments of this utility model, such as Figure 1 As shown, there are multiple second cutters 31, which are spaced apart along the first direction. There is one first cutter 21, and the first cutter 21 cooperates with the multiple second cutters 31 to meet the cutting requirements of multiple workpieces 200 respectively. When at least the first cutter 21 is movable along the second direction, the workpieces 200 located at the multiple second cutters 31 can be cut by one action of the first cutter 21, which is beneficial to improve processing efficiency. At the same time, the operation is simple and convenient for cutting the workpieces 200.

[0095] In embodiments of this utility model, the number of second cutters 31 can be flexibly set according to actual conditions. For example, the number of second cutters 31 can be as follows: Figure 1 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0096] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the cutting device 100 has a receiving cavity 13 extending through the first direction. The receiving cavity 13 can accommodate the clamp 300 that clamps the workpiece 200, satisfying the placement requirements of the clamp 300 within the cutting device 100, thereby facilitating the subsequent cutting of the workpiece 200. Furthermore, the receiving cavity 13 extends through the cutting device 100 in the first direction, facilitating the movement of the clamp 300 relative to the cutting device 100 in the first direction, satisfying the movement requirements of the workpiece 200, and avoiding collisions between the cutting device 100, the clamp 300, and the workpiece 200, effectively avoiding the risk of collision.

[0097] In some embodiments, such as Figures 1-3 , Figure 6 As shown, the cutting device 100 includes a support body 10, which includes a first support portion 101, a second support portion 102, and a third support portion 103. The second support portion 102 is connected to the first support portion 101 and extends along a second direction. The third support portion 103 is connected to the end of the second support portion 102 away from the first support portion 101 and extends along a third direction. A first cutter 21 is disposed on the third support portion 103 to limit the first cutter 21. A second cutter 31 is disposed on the first support portion 101 to limit the second cutter 31. A receiving cavity 13 is defined between the first support portion 101, the second support portion 102, the third support portion 103, the first cutter 21, and the second cutter 31, making it easy to place the fixture 300 inside the support body 10 and to facilitate the first cutter 21 and the second cutter 31 to cut the workpiece 200. The support body 10 has a simple structure, is easy to manufacture, and helps to reduce production costs.

[0098] In some embodiments, such as Figure 3 As shown, the first support portion 101 extends along the first direction, and the second support portion 102 and the third support portion 103 are multiple portions arranged at intervals along the first direction. The ends of the multiple second support portions 102 that are away from the third support portion 103 are all connected to the first support portion 101, which can improve the structural strength of the bracket body 10 and reduce the use of materials, thus helping to reduce production costs.

[0099] In embodiments of this utility model, the number of the second support portion 102 and the third support portion 103 can be flexibly set according to actual conditions. For example, the second support portion 102 and the third support portion 103 can be as follows: Figure 3 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0100] In some embodiments, such as Figures 1-3 , Figure 6 As shown, the support body 10 also includes a fourth support portion 104, which extends along the first direction. The ends of the plurality of third support portions 103 that are away from the second support portion 102 are all connected to the fourth support portion 104. The first cutter 21 is disposed on the fourth support portion 104 to ensure reliable positioning of the first cutter 21 and to improve the structural strength of the support body 10, avoid deformation and other problems, and help extend the service life of the cutting device 100.

[0101] According to some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the cutting device 100 also includes a clamping member 71, which is movable along the second direction. The clamping member 71 can clamp the clamping part 61 of the clamp 300 that clamps the workpiece 200, making the clamping part 61 of the clamp 300 clamp the workpiece 200 more reliably, avoiding problems such as the workpiece 200 flipping during cutting, and ensuring the reliability and accuracy of the workpiece 200 cutting.

[0102] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the cutting device 100 also includes a third driving member 72, which can drive the clamping member 71 to move along the second direction to meet the movement requirements of the clamping member 71, ensure reliable clamping of the clamping part 61, thereby ensuring reliable limiting of the workpiece 200, and can achieve automation, which is conducive to reducing manual operation and ensuring production efficiency.

[0103] In the embodiments of this utility model, the specific structure of the third driving member 72 can be set according to the actual situation.

[0104] For example, in some embodiments, such as Figure 3 and Figure 4 As shown, the third driving member 72 can be a cylinder or a linear motor. The third driving member 72 is connected to the clamping member 71, which can ensure that the third driving member 72 can reliably drive the clamping member 71 to move in the second direction.

[0105] For example, in some embodiments, the third drive member 72 includes a motor and a transmission mechanism, which are connected in a transmission manner. The transmission mechanism is also connected in a transmission manner to the clamping member 71. The motor drives the transmission mechanism to move, which in turn drives the clamping member 71 to move, thus fulfilling the movement requirement of the clamping member 71.

[0106] According to some embodiments of this utility model, such as Figure 4 As shown, the third driving member 72 is located on one side of the clamping member 71 along the second direction. The clamping member 71 includes a fixing part 713, which is located on one side of the clamp 300 along the third direction. The fixing part 713 forms a relief groove 712. Along the second direction, the groove opening 714 of the relief groove 712 is away from the clamp 300. The output end of the third driving member 72 is connected to the bottom wall of the relief groove 712, which can meet the connection requirements between the third driving member 72 and the clamping member 71. The output end of the third driving member 72 can extend into the relief groove 712. While avoiding interference at the end of the third driving member 72 away from the clamping member 71, it can meet the movement length requirements of the output end of the third driving member 72, ensuring reliable driving of the clamping member 71 and making the cutting device 100 compact in structure.

[0107] In addition, such as Figure 4As shown, the clamping member 71 includes an abutment end 711, which is connected to the fixing part 713. Along a third direction, the abutment end 711 is located on the side of the fixing part 713 facing the clamp 300. Along a second direction, the abutment end 711 is connected to the end of the fixing part 713 away from the clamp 300. The abutment end 711 can abut against the clamp 300. Therefore, by driving the clamping member 71 to move along the second direction via the third driving member 72, the abutment end 711 can abut against or disengage from the clamp 300, thereby fulfilling the required clamping requirement of the clamping member 71 against the clamp 300, ensuring reliable fixation of the workpiece 200. Furthermore, the clamping member 71 has a simple structure, is easy to manufacture, and helps reduce production costs.

[0108] In some embodiments of the resection device 100, including the support body 10, such as Figure 4 As shown, a clearance part 15 is provided on the lower end surface of the bracket body 10. The clearance part 15 can avoid the clamping member 71, thus avoiding interference between the clamping member 71 and the bracket body 10 and ensuring reliable movement of the clamping member 71.

[0109] In some embodiments of this utility model, at least one of the first cutter 21 and the second cutter 31 is a tungsten carbide component, that is, the first cutter 21 is a tungsten carbide component, or the second cutter 31 is a tungsten carbide component, or both the first cutter 21 and the second cutter 31 are tungsten carbide components. Tungsten carbide components have good structural strength, which can ensure good cutting effect on the workpiece 200. In addition, tungsten carbide components have high compressive strength and hot hardness, which can effectively reduce thermal deformation and help extend the service life of the first cutter 21 and / or the second cutter 31.

[0110] The processing equipment 400 according to an embodiment of the present invention includes a clamp 300 and a cutting device 100 for processing batteries according to an embodiment of the present invention. The clamp 300 can fix the workpiece 200, ensuring reliable fixation of the workpiece 200 and facilitating subsequent processing of the workpiece 200. Along a third direction, the clamp 300 is located on the side where the cutting edge of the first cutter 21 is away from the cutting edge of the second cutter 31. By allowing at least one of the first cutter 21 and the second cutter 31 to move along a second direction, the workpiece 200 can be cut, meeting the cutting requirements of the workpiece 200. Furthermore, the cutting edges of at least the first cutter 21 and at least the second cutter 31 are offset along a third direction, ensuring that the cut-off portion 202 of the workpiece 200 is completely cut open, ensuring a good cutting effect on the workpiece 200.

[0111] Since the cutting device 100 according to the present invention has the above-mentioned beneficial technical effects, the processing equipment 400 according to the present invention extends the first cutter 21 and the second cutter 31 along the first direction, and at least one of the first cutter 21 and the second cutter 31 is movable along the second direction to jointly cut the workpiece 200. The cutting edges of at least the first cutter 21 and at least the second cutter 31 are staggered along the third direction. The first direction, the second direction and the third direction are perpendicular to each other, which can ensure that the cut-off portion 202 of the workpiece 200 is completely cut open, ensuring a good cutting effect on the workpiece 200, which is conducive to improving production efficiency and reducing the difficulty of processing and assembly accuracy, which is conducive to reducing the production cost of the cutting device 100. At the same time, it avoids the first cutter 21 and the second cutter 31 cutting the workpiece 200 by abutting each other, which would cause collision, wear and vibration problems, ensuring the working reliability of the cutting device 100 and extending its service life. In addition, the limiting structure 32 can play an auxiliary positioning role for the first cutter 21, ensuring reliable movement between the first cutter 21 and the second cutter 31, avoiding problems such as collision between the blades of the first cutter 21 and the second cutter 31, and ensuring the processing reliability of the cutting device 100.

[0112] In related technologies, the cutting device is independent of other processes in the processing equipment (such as encapsulating, cutting, folding, and hot-pressing the aluminum-plastic film shell of the battery). It requires manual removal of the workpiece from other processes for cutting, and the workpiece needs to be repositioned. This results in poor coordination and large cumulative errors, such as cumulative errors greater than ±0.2mm, which leads to workpiece cut offset and affects the workpiece's processing pass rate. Furthermore, since the workpiece needs to be removed for cutting, the processing equipment needs to be stopped, which can easily affect processing efficiency. For example, the cycle time of the stop-cut mode is greater than 5 seconds per piece, which cannot be matched with high-speed production lines (e.g., high-speed production lines require more than 24PPM).

[0113] Therefore, in some embodiments of this utility model, such as Figures 1-4 , Figures 6-9As shown, the processing equipment 400 also includes a conveying mechanism 80. The fixture 300 is connected to the conveying mechanism 80. The conveying mechanism 80 can drive the fixture 300 to move along the first direction to the cutting device 100, so that the fixture 300 can move synchronously with the conveyor line, realizing dynamic cutting without stopping the line and avoiding the problem of cutting while the line is stopped. This results in higher cutting efficiency, increased production capacity, and high-speed operation, meeting the production cycle requirements. For example, it can achieve a cycle time of less than or equal to 1.8 seconds / piece, meeting the high-speed production line requirement of greater than 24 PPM. At the same time, the workpiece 200 is located on the fixture 300 and moved to the cutting device 100 by the conveying mechanism 80 for cutting. This avoids secondary positioning of the workpiece 200, ensuring the accuracy of cutting and meeting the required processing requirements. For example, the cut position error of the workpiece 200 is less than or equal to ±0.1mm.

[0114] According to some embodiments of this utility model, the clamp 300 is detachably mounted on the conveying mechanism 80, which facilitates the installation and disassembly of the clamp 300, as well as maintenance or replacement, and can meet different usage needs.

[0115] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the fixture 300 includes a base portion 62, a clamping portion 61, and an elastic element. The clamping portion 61 is rotatably disposed on the base portion 62. The workpiece 200 is clamped between the clamping portion 61 and the base portion 62. By rotating the clamping portion 61 on the base portion 62, the workpiece 200 can be clamped and released, making the operation of the fixture 300 simple. The elastic element is disposed between the clamping portion 61 and the base portion 62. The elastic element can drive the clamping portion 61 and the base portion 62 to clamp the workpiece 200, so that the clamping portion 61 can clamp the workpiece 200 under the action of the elastic force of the elastic element, ensuring that the workpiece 200 is reliably fixed between the clamping portion 61 and the base portion 62. At the same time, the fixture 300 has a simple structure, is easy to process and manufacture, and helps to reduce production costs. For example, the elastic element can be a spring, etc.

[0116] In some embodiments, such as Figure 8 As shown, along the third direction, the workpiece 200 and the elastic element are located on both sides of the rotation center of the clamping part 61 and the base part 62, respectively. The workpiece 200 is located at the end of the clamping part 61 and the base part 62 near the rotation center of the rotation center, and the clamping part 61 rotates around the rotation center of the clamping part 61 and the base part 62 under the elastic force of the elastic element, so that the end of the clamping part 61 near the first cutter 21 can clamp the workpiece 200, ensuring that the workpiece 200 is reliably fixed.

[0117] According to some embodiments of this utility model, such as Figure 9As shown, the clamping part 61 has a first groove 611 on the side facing the base part 62, and the base part 62 has a second groove 621 on the side facing the clamping part 61. The first groove 611 and the second groove 621 are opposite to and connected to each other. The workpiece 200 is located in the first groove 611 and the second groove 621. By the first groove 611 and the second groove 621 cooperating with the outer peripheral wall of the workpiece 200, the contact area between the clamping part 61 and the base part 62 and the workpiece 200 can be increased, effectively positioning the workpiece 200 and ensuring reliable positioning of the workpiece 200.

[0118] In some embodiments, such as Figure 8 and Figure 9 As shown, the workpiece 200 is a cylindrical battery. Along the cross-section perpendicular to the rotation center of the clamping part 61 and the base part 62, the first groove 611 and the second groove 621 are both formed in an arc shape, that is, the fixture 300 can perform contour processing to achieve adaptation to the workpiece 200, effectively position the battery, and ensure reliable positioning of the workpiece 200.

[0119] In some embodiments of this utility model, there can be multiple clamps 300 (two or more). The first groove 611 and the second groove 621 of the multiple clamps 300 have different shapes and / or sizes. The multiple clamps 300 can be interchangeably disposed on the conveying mechanism 80 to realize the connection between the multiple different clamps 300 and the conveying mechanism 80, thereby realizing the fixing and conveying requirements of workpieces 200 with different shapes and / or sizes, enabling the processing equipment 400 to process different workpieces 200, facilitating the versatility of the processing equipment 400, meeting the processing requirements of different workpieces 200, and avoiding the need to replace the entire clamps 300 and the conveying mechanism 80, which can reduce production costs.

[0120] The following describes in detail a specific embodiment of the processing equipment 400 according to the present invention with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0121] Reference Figure 1 As shown, the processing equipment 400 includes a fixture 300, a conveying mechanism 80, and a cutting device 100. The cutting device 100 has a receiving cavity 13 extending through a first direction. The fixture 300 is connected to the conveying mechanism 80.

The clamping portion 61 has a first groove 611 on the side facing the base portion 62, and the base portion 62 has a second groove 621 on the side facing the clamping portion 61. The first groove 611 and the second groove 621 are opposite to and communicate with each other. Along a cross section perpendicular to the rotation center of the clamping portion 61 and the base portion 62, both the first groove 611 and the second groove 621 are formed into an arc shape. The battery body portion 201 is located in the first groove 611 and the second groove 621. The elastic member can drive the clamping portion 61 and the base portion 62 to clamp the battery body portion 201.

[0123] like Figure 2 As shown, the cutting device 100 includes a support body 10, a first cutter 21, a second cutter 31, a limiting structure 32, a guide 42, a guide structure 34, a drive assembly 50, a third drive member 72, a linear bearing 14, a clamping member 71, a waste box 41, and a negative pressure device. The drive assembly 50 includes a first drive member 51 and a second drive member 52. The first cutter 21 and the second cutter 31 extend along a first direction, and the first cutter 21 and the second cutter 31 are movably disposed on the support body 10 along a second direction. The first cutter 21 is at least partially located above the second cutter 31, and the cutting edges of at least the first cutter 21 and at least the second cutter 31 are offset along a third direction. Along the third direction, the two sides of the first cutter 21 are a first side 23 and a second side 24, respectively. The second cutter 31 is located on the first side 23 of the first cutter 21. The second cutter 31 is provided with limiting structures 32 on both sides along the first direction. The limiting structures 32 are connected to the second cutter 31. The limiting structures 32 extend beyond the blade of the second cutter 31 along the second direction. The limiting structures 32 have clearance openings 321. Along the third direction, the clamp 300 is located on the side of the blade of the first cutter 21 away from the blade of the second cutter 31.

[0124] like Figure 2 and Figure 5 As shown, the support body 10 is provided with a first guide portion 11 and a second guide portion 12. The first guide portion 11 is a guide rail extending along the second direction, and the second guide portion 12 is a guide hole. The first cutter 21 is provided with a first guide member 22, which is a slider with a groove 221 extending along the second direction. The second cutter 31 is provided with a second guide member 33, which is a guide post extending along the second direction. The guide post is movably inserted into the guide hole along the second direction, and the linear bearing 14 is inserted into the guide hole and sleeved on the outside of the guide post.

[0125] like Figure 1As shown, along a third direction, the guide 42, guide structure 34, and waste container 41 are disposed on the side of the second cutter 31 facing away from the clamp 300. The guide structure 34 is located between the guide 42 and the second cutter 31. The guide 42 is connected to the second cutter 31. In the top-to-bottom direction, the surface of the guide structure 34 facing away from the clamp 300 is inclined in the direction facing away from the clamp 300. At least a portion of the waste container 41 is located below the blade of the second cutter 31, and at least a portion of the guide 42 is located above the waste container 41. The waste container 41 is provided with an air extraction port, and a negative pressure device is connected to the air extraction port, which is located at the bottom of the waste container 41.

[0126] When the processing equipment 400 is working, the drive conveying mechanism 80 moves the clamp 300 along the first direction into the receiving cavity 13 of the cutting device 100. At the same time, the workpiece 200 can pass through the clearance opening 321, so that the workpiece is located between the first cutter 21 and the second cutter 31. The third drive member 72 drives the clamping member 71 to move downward, so that the clamping member 71 clamps the clamping part 61. The first drive member 51 can drive the first cutter 21 to move downward, and through the slide groove 221 and the guide rail, the first cutter 21 is guided along the second direction. The second drive member 52 can drive the second cutter 31 to move upward, and through the guide post and the linear bearing 14, the second cutter 31 is guided along the second direction.

[0127] When the first cutter 21 and the second cutter 31 move toward each other in the second direction, the limiting structure 32 abuts against the first side 23 of the first cutter 21, and along the second direction, the blades of the first cutter 21 and the blades of the second cutter 31 are in contact with each other's surfaces. The first cutter 21 and the second cutter 31 cut the workpiece 200 together, so that the cut-out portion 202 can be cut off from the battery body portion 201, thus fulfilling the cutting requirements of the workpiece 200.

[0128] Waste materials such as the cut-off portion 202 after workpiece 200 is cut can enter the waste box 41 in sequence through the guide structure 34 and guide member 42. The negative pressure device can draw air from the waste box 41 through the air extraction port, which facilitates the collection of waste materials, avoids waste material residue after cutting, and ensures the cleanliness of the cutting device 100.
