Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The cutting device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0021] like Figures 1-4 As shown, the cutting device 100 according to an embodiment of the present utility model includes a cutting mechanism 1, a pressure roller mechanism 2, and a driving mechanism 3.
[0022] The cutting mechanism 1 includes a cutting assembly 11, which includes at least two cutting blades 111, which are positioned along a first direction (e.g., ...). Figure 1 The cutting blades 111 are arranged at intervals in the first direction shown. The pressure roller mechanism 2 includes a pressure roller 21, which is used to press the workpieces cut by the cutting blades 111. The drive mechanism 3 includes a drive motor 31, which is connected to the cutting mechanism 1 and the pressure roller mechanism 2 respectively. It is used to drive the cutting blade assembly 11 and the pressure roller 21 along the second direction (as shown in the first direction). Figure 1The second direction shown is used for movement, and the first and second directions are perpendicular.
[0023] It is understood that by including at least two cutters 111 arranged at intervals along the first direction, the cutter assembly 11 can cover multiple cutting positions in the first direction within a single stroke of the drive mechanism 3 driving the cutter assembly 11 along the second direction. This reduces the amount of repeated workpiece transfer in the first direction, increases the cutting cycle time, and thus increases the cutting output per unit time. It enables two or more cutting points to be formed simultaneously in a single stroke without increasing the reciprocating frequency of the cutter assembly 11, increasing the workpiece output that can be obtained in a single cutting, reducing the idle movement and waiting required to reach the next cutting position, further compressing the invalid time of a single stroke, improving overall efficiency, and reducing the space occupied by the cutting device 100.
[0024] Furthermore, the end face of the cutter 111 facing away from the drive mechanism 3 along the second direction is set as an inclined surface. The inclined surface serves as an inlet angle so that the cutter 111 first makes line contact with the workpiece from one side of the inclined surface, and then gradually expands to surface contact, thereby making it easier to cut the workpiece, reducing the impact on the workpiece, reducing burrs, chipping and dust, and improving the perpendicularity of the cut and the neatness of the edge.
[0025] It should be noted that, Figure 2 The diagram shows two cutters 111 for illustrative purposes. In this case, a single cut can yield two cut workpieces. However, after reading the following technical solution, a person skilled in the art will obviously understand that this solution can be applied to a solution with three or more cutters 111, which also falls within the protection scope of this utility model.
[0026] After the cutter 111 finishes cutting, the pressure roller 21 of the pressure roller mechanism 2 presses down on the workpiece cut by the cutter 111, thereby effectively suppressing the workpiece from lifting, slipping or shifting during the conveying process, ensuring that the workpiece is flat and does not slip when there is a transition during the conveying process, and improving the stability of the workpiece in the subsequent transfer process.
[0027] Meanwhile, by driving the cutter assembly 11 and the pressure roller 21 along the second direction with a single drive motor 31, the cutter assembly 11 and the pressure roller 21 can move synchronously by the same drive motor 31. This avoids a series of problems such as material blockage caused by inconsistent signal interaction response due to dual drives, further improving the stability of the cutting device 100. Moreover, by using a single drive motor 31, the number of drive components and debugging dimensions can be reduced, and maintenance points and fault coupling can be reduced.
[0028] In addition, by driving at least two cutters 111 of the cutter assembly 11 along the second direction through the same drive motor 31, the problem of asynchronous dual-motor drive in the prior art is effectively solved, ensuring that each cutter 111 moves synchronously and improving system stability.
[0029] It should be noted that the above-mentioned workpieces can be electrode sheets for electrochemical batteries, including but not limited to positive / negative electrode sheets for lithium-ion batteries. Of course, the workpieces can also be other sheet materials that need to be cut from strips.
[0030] According to an embodiment of the present invention, the cutting device 100 includes a cutting mechanism 1 comprising a cutting blade assembly 11, which includes at least two cutting blades 111 arranged at intervals along a first direction. The cutting blades 111 are used to cut workpieces, thereby increasing the cutting cycle time and improving the cutting output per unit time, effectively reducing the space occupied by the cutting device 100. A pressure roller mechanism 2 includes a pressure roller 21, which presses down on the workpieces cut by the cutting blades 111, ensuring the workpieces are flat and do not slip, thus improving the stability of the workpieces during subsequent transport. Simultaneously, a driving mechanism 3 includes a driving motor 31, which is connected to both the cutting mechanism 1 and the pressure roller mechanism 2, driving the cutting blade assembly 11 and the pressure roller 21 to move along a second direction. This avoids problems such as material blockage caused by inconsistent signal interaction response due to dual drives, further improving the stability of the cutting device 100.
[0031] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the drive mechanism 3 includes an output shaft 32. The output shaft 32 is a single shaft extending along a first direction. The output end of the drive motor 31 is connected to the output shaft 32 in a transmission connection. The cutting mechanism 1 and the pressure roller mechanism 2 are respectively connected to the output shaft 32 in a transmission connection.
[0032] Therefore, the output shaft 32 transmits the rotational power of the drive motor 31 to the cutter assembly 11 and the pressure roller mechanism 2 simultaneously, so that the same drive source drives the cutter assembly 11 and the pressure roller 21 to reciprocate along the second direction, and the action phase of the two is uniformly determined by the circumferential position of the output shaft 32. There is no need for cross-axis communication to synchronize the timing, thereby further avoiding a series of problems such as material blockage caused by inconsistent signal interaction response due to dual drive, and improving the cycle consistency and operation stability of the cutting device 100.
[0033] Furthermore, such as Figure 4As shown, the drive mechanism 3 also includes a reducer 33, which is connected to the output end of the drive motor 31, and the output shaft 32 is connected to the output end of the reducer 33. Thus, the reducer 33 transforms the high-speed, low-torque output of the drive motor 31 into a low-speed, high-torque output, making it easier to match the target cycle time of the cutter assembly 11 and the pressure roller 21. Furthermore, under high-cycle, frequent start-stop conditions, it helps maintain the repeatability of the reciprocating stroke and further enhances the reliability of the cutting device 100.
[0034] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the cutting mechanism 1 also includes a first transmission mechanism 12, which is connected to the output shaft 32 and the cutter assembly 11 respectively. Thus, the rotation of the output shaft 32 is converted into the reciprocating motion of the cutter assembly 11 along the second direction by the first transmission mechanism 12.
[0035] The first transmission mechanism 12 includes a first connecting rod, a second connecting rod, and a slider 121. One end of the first connecting rod is fixedly connected to the output shaft 32, and both ends of the second connecting rod are respectively hinged to the other end of the first connecting rod and the cutter assembly 11. The first transmission mechanism 12 is used to convert the rotational motion of the output shaft 32 into the linear motion of the cutter assembly 11 along the second direction.
[0036] Understandably, when the output shaft 32 rotates, the first connecting rod drives the second connecting rod to swing, which in turn drives the slider 121 to perform reciprocating linear motion along the second direction, thereby converting continuous rotation into reciprocating linear motion of the cutter assembly 11 along the second direction. Thus, the first transmission mechanism 12 converts the rotation of the output shaft 32 into the reciprocating motion of the cutter assembly 11 along the second direction, and the motion law of the first transmission mechanism 12 is realized by the mechanical structure, requiring no complex control, resulting in higher repeatability and reliability.
[0037] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the pressure roller mechanism 2 also includes a second transmission mechanism 22, which is connected to the output shaft 32 and the pressure roller 21 respectively. Thus, the rotation of the output shaft 32 is converted into the reciprocating motion of the pressure roller 21 along the second direction by the second transmission mechanism 22.
[0038] The second transmission mechanism 22 includes a transmission rod 221 and a drive wheel 222. The drive wheel 222 is sleeved and fixed on the output shaft 32. The drive wheel 222 has a track. One end of the transmission rod 221 along the second direction is movable in the track, and the other end is connected to the pressure roller 21. There are at least two points on the track that are at different distances from the axis of the output shaft 32.
[0039] It is understandable that when the drive wheel 222 rotates with the output shaft 32, the radial change of the track drives the transmission rod 221 to produce displacement in the second direction, thereby realizing the reciprocating motion of the pressure roller 21 along the second direction. Furthermore, through the contour of the track and its circumferential installation position, the starting point of the pressure roller 21, the dwell time, and the return time can be precisely set, thereby realizing the timing control of "cutting before pressing", effectively suppressing warping and slippage after cutting, reducing the risk of material blockage and sheet throwing, and improving the stability of conveying.
[0040] In some embodiments of this invention, during the rotation of the output shaft 32, the contact time between the cutter assembly 11 and the workpiece is earlier than the contact time between the pressure roller 21 and the workpiece. Therefore, this arrangement ensures that the pressure roller 21 presses down on the workpiece only after the cutter 111 has completed the cutting, guaranteeing a "cut first, press later" sequence and improving reliability.
[0041] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, there are multiple pressure rollers 21, which are arranged at intervals along the first direction. The second transmission mechanism 22 consists of multiple pressure rollers 21 that correspond one-to-one with the pressure rollers 21. Along the workpiece conveying direction, the pressure roller 21 located upstream of any two adjacent pressure rollers 21 is the first pressure roller 21, and the pressure roller 21 located downstream is the second pressure roller 21. During the rotation of the output shaft 32, the first pressure roller 21 contacts the workpiece earlier than the second pressure roller 21 contacts the workpiece.
[0042] Understandably, the first pressure roller 21 presses the workpiece after it is cut, and then the second pressure roller 21 presses it as the workpiece is conveyed. The first and second pressure rollers apply additional pressure and shape to the same workpiece at different times, further suppressing residual warping and displacement, improving the stability of transition and conveying, and avoiding overlapping, mis-pressing, and secondary displacement. Simultaneously, by setting different tracks in the second transmission mechanism 22 corresponding to the pressure rollers 21, the first pressure roller 21 contacts the workpiece earlier than the second pressure roller 21 during the rotation of the same output shaft 32, simplifying the overall structure and enabling high-speed continuous operation.
[0043] In some embodiments of this utility model, along the rotation direction of the output shaft 32, the point where the maximum distance between the track corresponding to the first pressure roller 21 and the central axis of the output shaft 32 is located in front of the point where the maximum distance between the track corresponding to the second pressure roller 21 and the central axis of the output shaft 32 is located.
[0044] It is understandable that the point where the maximum distance between the track and the central axis of the output shaft 32 is the strongest pressing moment during the pressing process of the pressure roller 21. By placing the point where the maximum distance between the track corresponding to the first pressure roller 21 and the central axis of the output shaft 32 is located in front of the point where the maximum distance between the track corresponding to the second pressure roller 21 and the central axis of the output shaft 32 is located, the points where the maximum distance between the two tracks and the central axes of the output shaft 32 is staggered in the circumferential direction, forming a stable mechanical phase difference. Thus, during the rotation of the output shaft 32, the contact time between the first pressure roller 21 and the workpiece is earlier than the contact time between the second pressure roller 21 and the workpiece.
[0045] In some embodiments of this utility model, such as Figure 1 , Figure 5 and Figure 6 As shown, the cutting device 100 also includes a transmission mechanism 4. The transmission mechanism 4 is arranged opposite to the cutting mechanism 1 along a second direction. The transmission mechanism 4 includes a first conveyor belt 41 and a vacuum assembly 42. The first conveyor belt 41 transports the workpiece to be cut along a first direction and has through holes. The vacuum assembly 42 is located on the side of the first conveyor belt 41 away from the cutting mechanism 1 and is used to adsorb the workpiece onto the first conveyor belt 41.
[0046] Understandably, after the first conveyor belt 41 transports the workpiece to be cut to the corresponding position, the drive mechanism 3 drives the cutter assembly 11 to move along the second direction toward the transmission mechanism 4, so that at least two cutters 111 can cut the workpiece. Subsequently, during the process of the first conveyor belt 41 transporting the cut workpiece to the downstream process, the drive mechanism 3 drives the pressure roller 21 to move along the second direction toward the transmission mechanism 4, so that the pressure roller 21 presses the workpiece cut by the cutter 111. This effectively suppresses the workpiece from lifting, slipping or shifting during the transport process, ensuring that the workpiece is flat and does not slip when there is a transition during transport, thus improving the stability of the workpiece in the subsequent transfer process.
[0047] Meanwhile, the vacuum component 42 creates negative pressure at the through hole of the first conveyor belt 41 to adsorb the workpiece onto the first conveyor belt 41, effectively preventing the workpiece from deviating after being cut by the cutter 111, further ensuring that the workpiece on the first conveyor belt 41 remains flat and in good contact, significantly suppressing warping, slippage and deviation, and reducing the risk of scraping and material blockage, thereby improving overall reliability.
[0048] The device has multiple through holes, which are spaced apart along the length of the first conveyor belt 41 to increase the adsorption area of the vacuum assembly 42 on the workpiece. This further ensures that the vacuum assembly 42 adsorbs the cut workpiece onto the first conveyor belt 41, thereby improving the overall reliability.
[0049] Furthermore, the vacuum assembly 42 includes a vacuum suction plate 421, and a first conveyor belt 41 surrounds the vacuum suction plate 421 and the first drive roller 44 of the first conveyor belt 41. The vacuum suction plate 421 is normally open, maintaining a negative pressure state to stably suction the workpiece. The first conveyor motor 43 of the first conveyor belt 41 drives the first drive roller 44 of the first conveyor belt 41 to rotate, thereby driving the first conveyor belt 41 to rotate around the vacuum suction plate 421, thus realizing the conveying of the workpiece. At the same time, by reducing the radius of the transition rounded corner at the end of the vacuum suction plate 421, the adsorption area of the vacuum suction plate 421 on the workpiece is increased, improving the adsorption coverage per unit length and the adhesion ability of the edge area, thereby further improving the stability of the joint and the bridge.
[0050] In some embodiments of this utility model, such as Figure 1 , Figures 5-7 As shown, the cutting device 100 also includes a feeding mechanism 5 and a receiving mechanism 6. The feeding mechanism 5 is located upstream of the transmission mechanism 4 along the workpiece conveying direction and is used to convey the workpiece to be cut to the first conveyor belt 41. The receiving mechanism 6 is located downstream of the transmission mechanism 4 along the workpiece conveying direction and is used to receive the cut workpiece conveyed by the first conveyor belt 41.
[0051] Thus, the feeding mechanism 5 stably feeds the workpiece to be cut into the first conveyor belt 41 along the first direction. After the cutting assembly 11 completes the downward cutting in the second direction, the first conveyor belt 41 transports the cut workpiece to the receiving mechanism 6. At the same time, during the process of the first conveyor belt 41 transporting the cut workpiece to the receiving mechanism 6, the pressure roller 21 presses the workpiece, effectively suppressing the workpiece from lifting, slipping or shifting, ensuring that the workpiece is flat and does not slip.
[0052] Furthermore, the feeding mechanism 5 includes a drive roller 51, a follower roller 52, and a motor for the drive roller 51. The follower roller 52 is driven to press against the drive roller 51 via a lifting mechanism 54, forming a clamping channel between the drive roller 51 and the follower roller 52. The motor drives the drive roller 51 to rotate, and the follower roller 52 rotates together with the material belt under the pressure, thereby stably conveying the workpiece to be cut to the transmission mechanism 4. Simultaneously, the lifting mechanism 54 effectively presses the follower roller 52 against the material belt, ensuring no slippage or slippage during conveying. In a specific embodiment, such as... Figure 1 , Figure 3 and Figure 4As shown, the pressure roller mechanism 2 includes a first pressure roller 21, a second pressure roller 21, a first transmission rod 221, a second transmission rod 221, and a cam. Along the first direction, one cutter 111 is located between the two first pressure rollers 21 and the second pressure roller 21. The cam is sleeved and fixed on the output shaft 32, and its two end faces along the axis of the output shaft 32 have a first track and a second track, respectively. One end of the first transmission rod 221 is movable in the first track, and the other end is connected to the first pressure roller 21. One end of the second transmission rod 221 is movable in the second track, and the other end is connected to the second pressure roller 21. Along the workpiece conveying direction, the first pressure roller 21 is located upstream of the second pressure roller 21. The maximum distance between the first track and the central axis of the output shaft 32 is located in front of the maximum distance between the second track and the central axis of the output shaft 32. Along the second direction, the first pressure roller 21 is arranged opposite to the transmission mechanism 4, and the second pressure roller 21 is arranged opposite to the receiving mechanism 6.
[0053] It is understandable that the electrode sheet cut by the cutter 111 located between the first pressure roller 21 and the second pressure roller 21, along the workpiece conveying direction, the workpiece located upstream is the first workpiece and the workpiece located downstream is the second workpiece. During the process of the first conveyor belt 41 conveying the first workpiece to the receiving mechanism 6, the first workpiece is first pressed by the first pressure roller 21 and then by the second pressure roller 21, so as to ensure that the first workpiece is flat and does not slip, thereby achieving smooth conveying to the receiving mechanism 6.
[0054] In some embodiments of this utility model, such as Figure 6 As shown, the cutting device 100 also includes a lifting assembly 7. The lifting assembly 7 is disposed on the transmission mechanism 4 and is used to lift the cutting mechanism 1 on the side of the transmission mechanism 4 facing the cutting mechanism 1. The lifting assembly 7 includes a cylinder 71 and a top block 72. The piston rod of the cylinder 71 is connected to the top block 72, and the top block 72 is disposed opposite to the cutting mechanism 1.
[0055] Therefore, to achieve rapid maintenance and replacement of the cutting mechanism 1, when the cutting blade 111 needs to be replaced, the fasteners connecting the cutting mechanism 1 and the transmission mechanism 4 are first released. Then, the lifting assembly 7 is activated, and the cylinder 71 pushes the top block 72 to lift the entire cutting mechanism 1 in the second direction, creating a gap between it and the transmission mechanism 4. In the lifted state, the cutting mechanism 1 is moved laterally along the cutting device 100 to complete the rapid blade replacement. When reinstalling, the operation is reversed in the order of reset, alignment, and tightening. Thus, this process can complete the lateral removal and reinstallation of the cutting mechanism 1 without disassembling the transmission mechanism 4, achieving quick disassembly, significantly shortening downtime, and improving replacement efficiency and operational safety.
[0056] In some embodiments of this utility model, such as Figure 1 and Figure 5As shown, the cutting device 100 also includes a roller assembly 8. The roller assembly 8 includes ball casters and a lifting member. The roller assembly 8 is located below the transmission mechanism 4, and one of the ball casters and the lifting member can be optionally supported on the table surface where the cutting device 100 is located.
[0057] Therefore, when it is necessary to replace or repair the transmission mechanism 4, first loosen the fasteners between the transmission mechanism 4 and the base of the cutting device 100, then lift the transmission mechanism 4 with the lifting component so that the ball casters support the table where the cutting device 100 is located and bear the weight. Then, with the help of the rolling friction between the ball casters and the table, the transmission mechanism 4 is smoothly pushed out to complete the inspection or replacement, realizing quick disassembly, significantly shortening downtime, and improving replacement efficiency and operational safety.
[0058] Furthermore, there are multiple roller assemblies 8, which are spaced apart along the 4 directions of the transmission mechanism, thereby reducing local stress and overturning risk through multi-point support, and improving replacement efficiency and operational safety.
[0059] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cutting device 100 also includes a dust removal mechanism 9. The dust removal mechanism 9 includes an air blowing assembly 91 and a collection assembly 92. The air blowing assembly 91 is used to provide compressed gas to the cutting mechanism 1, and the collection assembly 92 is located below the cutting mechanism 1 and is used to collect foreign objects generated during cutting by means of negative pressure.
[0060] Understandably, the air blowing assembly 91 continuously supplies dry compressed air to the cutter 111 and its adjacent area, stripping and directionally blowing away foreign objects such as filaments and dust generated during cutting from the blade surface of the cutter 111 and the workpiece surface. The collection assembly 92 forms a negative pressure zone below the blade to promptly suck in and remove the blown-away foreign objects, preventing leakage and thus keeping the blade surface of the cutter 111 clean, ensuring stable cutting quality, and reducing the risk of short circuits caused by foreign objects entering subsequent processes. Simultaneously, when the workpiece is an electrode sheet, the dust removal mechanism 9 removes foreign objects such as filaments and dust generated during cutting, ensuring the cleanliness of the electrode sheet, preventing short circuits in the electrode core due to the introduction of foreign objects, and improving overall reliability.
[0061] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cutter assembly 11 includes a connector 13. The connector 13 is used to connect multiple cutters 111. Thus, the drive mechanism 3 drives the connector 13 to reciprocate along the second direction, thereby driving the multiple cutters 111 to reciprocate along the second direction.
[0062] The connectors 13 are multiple, each corresponding to one of the multiple cutters 111. At least one pair of adjacent connectors 13 can move toward and away from each other along a first direction to change the distance between the two cutters 111 corresponding to the two connectors 13. Therefore, when at least one pair of adjacent connectors 13 can move toward and away from each other along the first direction, the distance between the two corresponding cutters 111 can be directly changed in the first direction, enabling rapid switching between workpieces of different specifications. Simultaneously, by adjusting the two connectors 13 to change the distance between the two cutters 111, it is ensured that the two cutters 111 remain parallel, have consistent blade placement, and maintain accurate repeatability after adjustment, thus balancing dimensional consistency and stability under high-cycle operation.
[0063] For example, at least one of the two adjacent connectors 13 has a slotted hole extending in a first direction, which, together with the pressure plate, forms a slidable connection. By loosening the locking bolt, the connector 13 is pushed to the target position along the slotted hole direction, and then the pressure plate and bolt are tightened to change the distance between the two connectors 13; or, at least one pair of adjacent connectors 13 are connected by an indirect member, and by changing the length of the indirect member along the first direction, the distance between the two connectors 13 is changed.
