Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to a cutting device. Background Technology

[0002] With the advancement of green and low-carbon development, the new energy industry has achieved rapid development, and the quality of lithium batteries has also received much attention. Regularly testing the coating amount of the positive and negative electrodes of the battery core is a key parameter to ensure the quality of the battery cell.

[0003] Current testing methods are mainly divided into X-ray equipment testing and manual testing. X-ray equipment testing has drawbacks such as high cost, high equipment failure rate, complex operation, and long time consumption. Manual testing usually involves manually cutting the core to obtain its longitudinal section, and then observing and measuring the longitudinal section to determine the amount of coating of the negative electrode sheet over the positive electrode sheet and the amount of coating of the separator over the negative electrode sheet. However, manual testing requires operators to manually fix the core. Since it is difficult to ensure the uniformity and stability of the fixing force by manual fixing, the core is prone to displacement or loosening under the action of external cutting force, causing problems such as core cut deformation, ultimately leading to deviations in test data and poor test accuracy. Utility Model Content

[0004] In view of this, this application provides a cutting device to solve the problem of poor detection accuracy of the positive and negative electrode coating amount of the core in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: A cutting device, comprising: A support mechanism for holding the workpiece to be cut; A fixing mechanism is provided on the support mechanism. The fixing mechanism can switch between a first state and a second state. In the first state, the fixing mechanism is used to fix the workpiece to be cut to the support mechanism. In the second state, the fixing mechanism is used to separate from the workpiece to be cut so that the workpiece to be cut can move relative to the support mechanism. A cutting tool, rotatably mounted on the support mechanism, is used to cut the workpiece to be cut.

[0006] Optionally, the fixing mechanism includes a pressure plate and a telescopic structure. The telescopic structure is disposed on the support mechanism. The pressure plate is disposed opposite to the support mechanism along the height direction and is movably connected to the support mechanism along the height direction through the telescopic structure. In the first state, the pressure plate is used to press the workpiece to be cut against the support mechanism; in the second state, the pressure plate is used to separate from the workpiece to be cut.

[0007] Optionally, the support mechanism includes a base and a support platform arranged along the height direction, the telescopic structure is disposed on the base, and the support platform is disposed on the surface of the base facing the pressure plate, the support platform being used to support the workpiece to be cut.

[0008] Optionally, the surface of the pressure plate facing the support mechanism is provided with a first buffer pad.

[0009] Optionally, the surface of the support mechanism used to support the workpiece to be cut is provided with a second buffer pad.

[0010] Optionally, the support mechanism includes a first part and a second part connected along the length direction, with a gap between the first part and the second part located within the rotation range of the cutter. The first part and the second part are connected by a length adjustment assembly, and the first part and the second part can move relative to each other along the length direction in a direction that brings them closer or further apart.

[0011] Optionally, the first part includes a first base plate, the second part includes a second base plate, and the length adjustment assembly includes a first connector and a plurality of fasteners. The first connector is provided with an elongated hole extending along the length direction. Among the plurality of fasteners, at least one of the fasteners passes through the elongated hole and is connected to the first base plate, and at least one of the fasteners passes through the elongated hole and is connected to the second base plate.

[0012] Optionally, the first base plate is provided with a first groove, and the second base plate is provided with a second groove.

[0013] Optionally, the cutting tool includes a blade and a handle, wherein the handle is a tapered structure and the tip of the tapered structure is connected to the blade.

[0014] Optionally, the outer surface of the handle is provided with an anti-slip structure.

[0015] In this embodiment, the workpiece to be cut is fixed to the support mechanism by a fixing mechanism. The fixing mechanism provides a stable fixing force to the workpiece, preventing displacement or loosening under external force during cutting. When the cutting device in this embodiment is used to cut the core, the fixing mechanism secures the core to prevent displacement or loosening under cutting force, resulting in an effective longitudinal section of the core. This allows for clear observation of the relative positions of the positive electrode, negative electrode, and separator. Measuring the relative positions of the positive electrode, negative electrode, and separator effectively ensures the coating amount parameters of the core in its original state, improving detection accuracy. Therefore, this embodiment solves the problem of poor detection accuracy in manual detection of the positive and negative electrode coating amount of cores in the prior art.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figures 1-6 As shown in the figure, this application embodiment provides a cutting device for cutting a workpiece 600, which may be a roll core. This cutting device includes a support mechanism 100, a fixing mechanism 200, and a cutting tool 300.

[0026] The support mechanism 100 is used to place the workpiece 600 to be cut.

[0027] A fixing mechanism 200 is disposed on the support mechanism 100. The fixing mechanism 200 can switch between a first state and a second state. In the first state, the fixing mechanism 200 is used to fix the workpiece 600 to be cut onto the support mechanism 100, so that the support mechanism 100 and the workpiece 600 to be cut are relatively fixed. In the second state, the fixing mechanism 200 is used to separate from the workpiece 600 to be cut, so that the workpiece 600 to be cut can move relative to the support mechanism 100, and the workpiece 600 to be cut is in a free state. This realizes the action of placing the workpiece 600 to be cut onto the support mechanism 100 before cutting and the action of removing the cut workpiece 600 from the support mechanism 100 after cutting.

[0028] The cutting tool 300 is rotatably mounted on the support mechanism 100 and is used to cut the workpiece 600 to be cut.

[0029] In this embodiment, the workpiece 600 to be cut is fixed to the support mechanism 100 by the fixing mechanism 200. The fixing mechanism 200 provides a stable fixing force to the workpiece 600, preventing displacement or loosening of the workpiece 600 under external force during cutting. When the cutting device in this embodiment is used to cut the core, the fixing mechanism 200 is used to fix the core to prevent displacement or loosening under cutting force, obtaining an effective longitudinal section of the core. This allows for clear observation of the relative positions of the positive electrode, negative electrode, and separator, and measurement of the relative positions of the positive electrode, negative electrode, and separator, effectively ensuring the coating amount parameters of the core in its original state and improving detection accuracy. Therefore, this embodiment can solve the problem of poor detection accuracy of manual detection of the positive and negative electrode coating amount of the core in the prior art.

[0030] The fixing mechanism 200 has various structures. In one optional embodiment, the fixing mechanism 200 may include a clamping mechanism, which may include multiple jaws, such as two, wherein the two jaws are arranged opposite each other. When the clamping mechanism is in the clamping state, the two oppositely arranged jaws of the clamping mechanism can respectively abut against the two ends of the workpiece 600 to be cut, thereby clamping the workpiece 600 to be cut and fixing it to the support mechanism 100. When the clamping mechanism is in the non-clamping state, the workpiece 600 to be cut is not fixed and is in a free state.

[0031] In another alternative embodiment, the fixing mechanism 200 may include a pressure plate 210 and a telescopic structure 220. The telescopic structure 220 is mounted on the support mechanism 100. The pressure plate 210 is disposed opposite to the support mechanism 100 along the height direction b and is movably connected to the support mechanism 100 along the height direction b through the telescopic structure 220, so that a variable space for accommodating the workpiece 600 to be cut is formed between the pressure plate 210 and the support mechanism 100, and the fixing mechanism 200 can switch between a first state and a second state.

[0032] After the workpiece 600 to be cut is placed on the support mechanism 100, in the first state, the pressure plate 210 presses the workpiece 600 to be cut onto the support mechanism 100. In the second state, the pressure plate 210 and the workpiece 600 to be cut are separated, so that the workpiece 600 to be cut is in a free state and can be removed from the support mechanism 100.

[0033] The fixing mechanism 200 of this structure forms a large-area contact with the workpiece 600 to be cut through the pressure plate 210, so as to achieve the pressing and fixing of the workpiece 600 to be cut. Due to the large contact area, the pressing force applied to the workpiece 600 to be cut can be effectively dispersed, reducing the pressure per unit area, thereby reducing the risk of plastic deformation or surface damage to the workpiece 600 to be cut due to local stress concentration.

[0034] The telescopic structure 220 can extend and retract along the height direction b, thereby causing the pressure plate 210 to move along the height direction b towards or away from the support mechanism 100. The movement of the pressure plate 210 causes the size of the variable space to change in the height direction b. When the workpiece 600 to be cut is located in the variable space, or when the workpiece 600 to be cut passes through the variable space (i.e., is partially located in the variable space), the movement of the pressure plate 210 can press the workpiece 600 to be cut tightly or release the workpiece 600 to be cut.

[0035] The telescopic structural component 220 can be a telescopic cylinder such as a pneumatic cylinder or a hydraulic cylinder. The cylinder body can be mounted on the support mechanism 100 via bolts or other connecting parts. The piston rod of the telescopic cylinder can be connected to the pressure plate 210 via bolts or other connecting parts. When the telescopic cylinder extends, it can move the pressure plate 210 away from the support mechanism 100, making the variable space between the pressure plate 210 and the support mechanism 100 larger, so that the workpiece 600 to be cut can be placed into or removed from the variable space. When the telescopic cylinder retracts, it can move the pressure plate 210 closer to the support mechanism 100, making the variable space smaller, so that the workpiece 600 to be cut can be pressed tightly when it is located in or passes through the variable space.

[0036] Optionally, along the width direction c, the pressure plate 210 may be connected to a telescopic structure 220 at one end or at both ends. One end of the pressure plate 210 may be connected to one, two, or more telescopic structures 220. The specific number can be adjusted according to the dimensions of the pressure plate 210 in the length direction a to ensure that the pressure plate 210 can apply pressure evenly to the workpiece 600 to be cut. The accompanying drawings of this application illustrate this with two telescopic structures 220 connected to one end of the pressure plate 210. It should be noted that the aforementioned length direction a, height direction b, and width direction c refer to the length direction, height direction, and width direction of the support mechanism 100, respectively, and these three directions are perpendicular to each other.

[0037] Of course, the telescopic structural component 220 can also be other telescopic structural components such as an electric telescopic pole.

[0038] The support mechanism 100 has various structures. In one optional embodiment, the support mechanism 100 may include a base 110 and a telescopic structural member 220 may be installed on the surface of the base 110. When the workpiece 600 to be cut needs to be cut, the workpiece 600 to be cut is placed on the base 110, and the cutting action is performed after the workpiece 600 is fixed.

[0039] However, when using the support mechanism 100 with this structure, the dimension of the workpiece 600 to be cut in the height direction b needs to be greater than or equal to the dimension of the telescopic structure 220 in that direction so that the pressure plate 210 can effectively press the workpiece 600 to be cut. This size matching requirement limits the adaptability of the cutting device to thinner or smaller workpieces, which limits its application range in practical applications and reduces the versatility and process flexibility of the cutting device.

[0040] Therefore, in another alternative embodiment, the support mechanism 100 may include a base 110 and a support platform 120 arranged along the height direction b, a telescopic structure 220 is mounted on the base 110, and the support platform 120 is disposed on the surface of the base 110 facing the pressure plate 210, and the support platform 120 is used to support the workpiece 600 to be cut.

[0041] Compared to the embodiment where the support mechanism 100 only includes the base 110 and the telescopic structure 220 is mounted on the surface of the base 110, this embodiment effectively shortens the distance between the pressure plate 210 and the support mechanism 100 in the height direction b by adding a support platform 120. This structural design allows the cutting device to adapt to and stably fix a larger range of cut parts 600 in the height direction b, thereby expanding the processing application range of the cutting device.

[0042] Of course, in other alternative embodiments, the support mechanism 100 may also include only the base 110, and at least a portion of the telescopic structure 220 may be embedded in the base 110 to reduce the height of the telescopic structure 220 exposed outside the base 110 in the height direction b. Compared to the embodiment where the support mechanism 100 includes only the base 110 and the telescopic structure 220 is mounted on the surface of the base 110, the partial embedding of the telescopic structure 220 in the base 110 also allows the cutting device to adapt to and stably fix a larger range of cut pieces 600 in the height direction b, thereby expanding the processing application range of the cutting device.

[0043] The support mechanism 100 can be made of materials such as bakelite, stainless steel, aluminum alloy, or acetal alloy. Other materials can also be used; this application does not limit the material of the support mechanism 100. The corners of both the base 110 and the support platform 120 can be rounded. The height of the support platform 120 in the direction from the pressure plate 210 to the support mechanism 100 can be 10-50mm.

[0044] To alleviate the problem of surface damage to the workpiece 600 when it is pressed, a first buffer pad can be provided on the surface of the pressure plate 210 facing the support mechanism 100, and a second buffer pad can be provided on the surface of the support mechanism 100 used to support the workpiece 600. Both the first and second buffer pads can be rubber pads, silicone pads, or felt pads.

[0045] In this case, by providing buffer pads in the contact areas of the pressure plate 210 and the support mechanism 100 with the workpiece 600 to be cut, it is possible to prevent the workpiece 600 from being damaged, scratched, or plastically deformed due to direct contact with the surfaces of the pressure plate 210 and the support mechanism 100 during the clamping process. At the same time, the elastic properties of the buffer pads help to improve the fit between the clamping surface and the workpiece 600 to be cut, further enhancing the stability of fixing the workpiece 600 to be cut.

[0046] In addition, the second buffer pad is elastic. The second buffer pad on the surface of the support mechanism 100 can elevate the workpiece 600 to be cut. When cutting the workpiece 600, the tool 300 can cut the workpiece 600 completely and then move a distance towards the second buffer pad so that the tool 310 can completely cut the workpiece 600.

[0047] In this embodiment, the support mechanism 100 may include a first part and a second part connected along the length direction a, with a gap between them. This gap is located within the rotation range of the cutter 300, allowing the cutter 300 to continue moving a distance along the cutting direction after cutting the workpiece 600, thereby cutting off the workpiece 600. The first part and the second part are connected by a length adjustment assembly 500, and the first part and the second part can move relative to each other along the length direction a, either moving closer to each other or further apart. In this case, adjusting the length of the support mechanism 100 allows the cutting device to process workpieces 600 with a larger length range.

[0048] The length adjustment component 500 has various structures. In one optional embodiment, the length adjustment component 500 can be a telescopic cylinder such as a pneumatic cylinder or a hydraulic cylinder. The telescopic cylinder connects the first part and the second part. The telescopic cylinder can extend and retract to change the distance between the first part and the second part, thereby adjusting the length of the support mechanism 100.

[0049] In another alternative embodiment, the first part may include a first base plate 111, the second part may include a second base plate 112, and the length adjustment assembly 500 may include a first connector 510 and a plurality of fasteners 520, wherein the fasteners 520 may be bolts. The first connector 510 is provided with an elongated hole 511 extending along the length direction a. Among the plurality of fasteners 520, at least one fastener 520 passes through the elongated hole 511 and is connected to the first base plate 111, and at least one fastener 520 passes through the elongated hole 511 and is connected to the second base plate 112. This structure of the length adjustment mechanism is reliable and low in cost, which helps to reduce the cost of the cutting device.

[0050] As described above, the support mechanism 100 includes a base 110 and a support platform 120. The base 110 includes the first base plate 111 and the second base plate 112 described above. The support platform 120 includes a first step 121 and a second step 122. The first step 121 can be fixedly disposed on the first base plate 111, and the second step 122 can be fixedly disposed on the second base plate 112. When the support mechanism 100 includes the above structure, the first part may further include the first step 121 disposed on the first base plate 111, and the second part may further include the second step 122 disposed on the second base plate 112.

[0051] The first step 121 and the second step 122 can be fixed to the first base plate 111 and the second base plate 112 by welding, bolting or other means, respectively. The first step 121 and the second step 122 can also be integrally formed with the first base plate 111 and the second base plate 112, respectively.

[0052] There are several ways to connect the first base plate 111 and the second base plate 112 through the first connector 510 and two fasteners 520, thereby making the length of the support mechanism 100 adjustable.

[0053] In an optional embodiment, the fastener 520 can be a threaded connector, such as a bolt. Multiple bolt holes distributed along the length direction a can be provided on both the first base plate 111 and the second base plate 112. The fastener 520 passes through the elongated hole 511 and connects with one of the bolt holes on the first base plate 111 to connect the first connector 510 and the first base plate 111. Similarly, the fastener 520 passes through the elongated hole 511 and connects with one of the bolt holes on the second base plate 112 to connect the first connector 510 and the second base plate 112. The connection of these three components achieves the connection between the first base plate 111 and the second base plate 112. The different bolt holes on the first base plate 111 and the fastener 520 can be matched with different bolt holes on the second base plate 112 to adjust the length of the support mechanism 100.

[0054] In another optional embodiment, the first base plate 111 is provided with a first groove, and the second base plate 112 is provided with a second groove. Among the plurality of fasteners 520, at least one fastener 520 passes through the elongated hole 511 and abuts against the bottom of the first groove (and the abutting force of the fastener 520 may cause slight deformation of the bottom of the first groove, and the end of the fastener 520 may be embedded in the bottom of the first groove), so that a large static friction force is formed between the fastener 520 and the bottom of the first groove, generating resistance to the relative movement of the two, so that the fastener 520 is connected to the first base plate 111. At the same time, the fastener 520... The head of 20 presses the first connector 510 onto the first base plate 111, fixing the two relatively and thus connecting the first connector 510 and the first base plate 111. At least one fastener 520 passes through the elongated hole 511 and abuts against the bottom of the second groove to connect the first connector 510 and the second base plate 112 (similar to connecting the first base plate 111 and the first connector 510 via the fastener 520, which will not be described again here). In this way, the first connector 510 is connected to the first base plate 111 and the second base plate 112 respectively, thus connecting the first base plate 111 and the second base plate 112.

[0055] Specifically, the fastener 520 can be a bolt, and a washer can be provided between the head of the bolt and the first connecting member 510 to increase the contact area. The end of the bolt facing away from the head of the fastener 520 abuts against the bottom of the first groove, forming a large static friction force between it and the bottom of the first groove. The head of the fastener 520 presses the first connecting member 510 against the side wall of the first base plate 111, thereby connecting the first connecting member 510 to the first base plate 111. The connection of the first connecting member 510 and the second base plate 112 by bolts is similar and will not be described in detail here.

[0056] In this case, the fastener 520 can pass through any position of the elongated hole 511 and then abut against the first base plate 111 or the second base plate 112, so that the length of the support mechanism 100 can be any length between the maximum length and the minimum length, thereby improving the length adjustment flexibility of the support mechanism 100.

[0057] The length of both the first groove and the second groove can be 50mm. The end of the first groove near the second base plate 112 can be formed on the end of the first base plate 111 facing the second base plate 112, and the end of the second groove near the first base plate 111 can be formed on the end of the second base plate 112 facing the first base plate 111, so that the distance between the first base plate 111 and the second base plate 112 can be 0-100mm.

[0058] The first groove and the second groove can be respectively provided on the side walls of the first base plate 111 and the second base plate 112, and the first connector 510 is connected to the side wall of the support mechanism 100. Of course, the first connector 510 can also be connected to the edge position of the surface of the first base plate 111 and the second base plate 112 facing the pressure plate 210. This application does not limit the specific connection position of the first connector 510.

[0059] In the width direction c, the support mechanism 100 may have a length adjustment component 500 on one side or on both opposite sides. When performing a cutting operation, one side of the cutting device (the side along the width direction c) may abut against a limiting device (e.g., a wall) to further improve the positional stability of the cutting device during the cutting process.

[0060] The cutting tool 300 may include a blade 310 and a handle 320. The blade 310 is used to cut the workpiece 600. The blade 310 may be made of materials such as aluminum alloy, tungsten steel, or stainless steel. The handle 320 is a tapered structure. The handle 320 may be designed and machined using a draft die T-shaped stage. The tip of the tapered structure is connected to the blade 310, making it easy for the operator to hold the handle 320 and operate the cutting tool 300. The handle 320 may be made of wood. Of course, the material of the handle 320 may also be aluminum alloy, stainless steel, etc. This application does not limit the material of the handle 320.

[0061] In a further technical solution, the outer surface of the handle 320 can be provided with an anti-slip structure. The anti-slip structure can be an embossed design on the surface of the handle 320, or it can be multiple raised structures on the surface of the handle 320. In this case, it can prevent the operator from holding the handle 320 unsteadily.

[0062] The cutting tool 300 can be mounted on the support mechanism 100 (e.g., mounted on the first base plate 111 or the second base plate 112) via the second connecting member 400. The second connecting member 400 can be a flat structure or an L-shaped structure. The L-shaped structure includes a first connecting part and a second connecting part. The first connecting part can fit against the first base plate 111 and be fixedly connected to the first base plate 111 by bolts. The cutting tool body 310 can be rotatably mounted on the second connecting part via a structure such as a pin.

[0063] Optionally, the rotation range of the cutter 300 can be 0-180 degrees, so that the cutter 300 can cut the workpiece 600 of different thicknesses. Of course, in other optional embodiments, the rotation range of the cutter 300 can also be 0-360 degrees. This application does not limit this, as long as it can complete the cutting of the workpiece 600.

[0064] The cutting device provided in this application embodiment can be used to cut the core, and to cut the core longitudinally or at an angle to obtain an effective longitudinal section. After cutting, the first connecting piece 510 is removed, and the first base plate 111 and the second base plate 112 are separated. Under the fixed state of the core by the fixing mechanism 200, the relative positional relationship of the core's positive electrode sheet, negative electrode sheet and separator is measured using a measuring tool. This can effectively ensure the coating amount parameters of the core in its original state and improve the detection accuracy.

[0065] The cutting device provided in this application embodiment can be used to cut the core, and the core can be cut manually to obtain an effective longitudinal section of the core, thereby accurately measuring the core coverage. Compared with X-ray equipment inspection, the cutting device in this application has advantages such as simplified structure, portable operation, short operation process, and short inspection time.
