Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a cutting device and a method for cutting material strips. Background Technology

[0002] With the development of new energy vehicles, the technological level of the lithium battery industry is also getting higher and higher, and the requirements for battery safety performance are also getting higher and higher. Among them, the quality of the electrode sheets of the formed battery has a significant impact on the battery's safety performance.

[0003] In the battery manufacturing process, electrode strips need to be cut to form electrodes. If the cutting device used for cutting is not precise enough, it will create wires at the cutting edge. These wires may puncture the separator, causing a short circuit inside the battery. Summary of the Invention

[0004] Therefore, this application proposes a cutting device and a method for cutting strips, which can adjust the cutting distance, improve the cutting accuracy of the cutting device, and thus improve the cutting quality of the strips.

[0005] A first aspect of this application provides a cutting device, comprising: a first cutter; and an adjusting mechanism for adjusting the position of the first cutter. The adjusting mechanism includes a screw and an adjusting member, the adjusting member being sleeved on the screw and threadedly engaged with the screw. The adjusting member and the first cutter are wedge-shapedly engaged by a pair of mating surfaces. The screw is configured to rotate to drive the adjusting member to move axially along the screw, so that the adjusting member pushes the first cutter to move in a first direction, the first direction being perpendicular to the axial direction of the screw.

[0006] Rotating the screw drives the adjusting member to move along the screw's axial direction. The adjusting member and the first cutter are engaged by a pair of wedge-shaped mating surfaces, thereby pushing the first cutter to move in a direction perpendicular to the screw's axial direction. This allows adjustment of the cutter spacing of the cutting device, improving the cutting accuracy and thus the cutting quality of the material strip. When using the cutting device to cut electrode sheets, it improves the cutting quality of the electrode sheets, thereby enhancing the safety performance of the battery cells. Furthermore, the moving direction of the adjusting member is perpendicular to the moving direction of the first cutter, allowing for a compact adjusting mechanism that occupies less space, thus reducing the overall size and dimensions of the cutting device.

[0007] According to some embodiments of this application, the acute angle between the axial direction of the screw and the mating surface is smaller than the acute angle between the first direction and the mating surface.

[0008] When the screw is rotated, the displacement of the adjusting component is greater than that of the first cutter. Thus, with the same displacement of the adjusting component, the first cutter has a smaller displacement, which improves the movement accuracy of the first cutter, thereby improving the spacing adjustment accuracy of the cutting device and improving the cutting quality of the strip.

[0009] According to some embodiments of this application, the adjusting mechanism further includes: a first elastic element disposed between the screw and the adjusting element to tension the adjusting element and the screw along the axial direction of the screw.

[0010] The first elastic element tensions the adjusting element and the screw along the axial direction of the screw, which can make the internal thread of the adjusting element and the external thread of the screw tightly engage, and prevent the adjusting element and the screw from being relatively loose, causing the first cutter to shake in the first direction, which would change the cutting distance of the cutting device and affect the cutting quality of the material strip.

[0011] According to some embodiments of this application, the first cutter includes a first portion, a second portion, and a first guide shaft. The first portion is used to engage with the adjusting member in a wedge shape, and the second portion forms the cutting edge of the first cutter. The first portion and the second portion are respectively connected to both sides of the guide shaft along the first direction.

[0012] The cutting edge of the first cutter and the mating surface that engages with the wedge-shaped adjustment component are respectively formed on both sides of the first cutter along the first direction. This maximizes the distance between the cutting edge and the mating surface, effectively dissipating the vibration generated by the cutting edge as it is transmitted to the adjustment mechanism. This reduces the vibration amplitude of the adjustment mechanism and prevents the adjustment mechanism from loosening during use, which could lead to changes in the cutter spacing and affect the cutting quality of the strip.

[0013] According to some embodiments of this application, the adjustment mechanism includes two screws and two adjustment members. The screws and adjustment members are respectively disposed on a first side and a second side opposite to each other along the first direction of the first portion, and are wedge-shaped with the first portion. One of the two adjustment members is configured to push the first cutter to move along the first direction toward the first side, and the other of the two adjustment members is configured to push the first cutter to move along the first direction toward the second side opposite to the first side.

[0014] A screw and a corresponding adjusting component together constitute an adjusting assembly. Two adjusting assemblies are used to push the first cutter to move in opposite directions along a first direction. When the screw of one adjusting assembly is rotated, the corresponding adjusting component actively moves along the first direction, while the adjusting component of the other adjusting assembly moves passively. By setting two adjusting assemblies, the position of the first cutter can be precisely adjusted in opposite directions along the first direction, thereby controlling the increase or decrease of the cutter spacing of the cutting device.

[0015] According to some embodiments of this application, the first direction is parallel to the thickness direction of the first cutter.

[0016] Pushing the first cutter along its thickness direction to adjust the cutter spacing of the cutting device not only facilitates the calculation of the cutter spacing adjustment amount, but also allows for a larger adjustment of the cutter spacing with a small displacement of the first cutter, thus achieving high spacing adjustment accuracy.

[0017] According to some embodiments of this application, the cutting device further includes: a second cutter; and a driving component configured to drive the first cutter and the second cutter to move relative to each other along a second direction, so that the first cutter and the second cutter jointly cut the strip, the second direction being perpendicular to the first direction.

[0018] The first and second cutters cut the material strip together. The distance between the first and second cutters along their thickness direction is the cutting distance of the cutting device. Adjusting the first cutter to move closer to or further away from the second cutter in the first direction can effectively adjust the cutting distance of the cutting device.

[0019] According to some embodiments of this application, the cutting device further includes a first bracket and a second bracket, the first bracket and the second bracket being slidably engaged along the second direction, the first cutter being mounted on the first bracket, and the second cutter being mounted on the second bracket.

[0020] The first support and the second support slide together in the second direction, which can guide the first cutter and the second cutter to move closer or further apart in the second direction, making the cutting process stable and reliable.

[0021] According to some embodiments of this application, the first bracket includes a third part, a fourth part, and a second guide shaft. The third part and the fourth part are located on opposite sides of the second bracket along the second direction. The second guide shaft extends along the second direction and is slidably inserted through the second bracket. The second guide shaft connects the third part and the fourth part. The first cutter and the adjustment mechanism are mounted on the third part, and the drive assembly is mounted on the second bracket and connected to the fourth part.

[0022] The third part is equipped with the first cutter and the adjustment mechanism, and the fourth part cooperates with the drive assembly. The third part and the fourth part are located on both sides of the second bracket along the second direction, which enables the drive assembly to be located on one side of the second bracket and the first cutter and the adjustment mechanism to be located on the other side of the second bracket. The positions of the first cutter, the adjustment mechanism and the drive assembly are reasonably arranged, making the cutter device compact in structure and small in size.

[0023] According to some embodiments of this application, the driving assembly includes: a driving member mounted on the second bracket; a first connecting member, one end of which is connected to the output shaft of the driving member; and a second connecting member, one end of which is rotatably connected to the other end of the first connecting member, and the other end of which is rotatably connected to the first bracket, so that the driving member can drive the first bracket to reciprocate relative to the second bracket through the first connecting member and the second connecting member.

[0024] The driving component drives the first bracket to move along the second direction in a rotating manner through the first and second connecting components. This enables the first bracket to reciprocate at high speed along the second direction with minimal impact on the second frame, thus mitigating vibration of the cutting device under high-speed cutting conditions.

[0025] According to some embodiments of this application, the cutting device further includes: a holding member, movably mounted on the first cutter along the second direction, for holding the surface of the strip to be cut; and a second elastic member disposed between the first cutter and the holding member.

[0026] When the first and second cutting blades approach each other, the holding member presses against the surface of the strip, and by compressing the second elastic member, the first cutting blade is allowed to continue to approach the second cutting blade in the second direction to cut the strip. Furthermore, the holding member elastically holds the strip, positioning it during the cutting process to ensure stable and reliable cutting action.

[0027] According to some embodiments of this application, the holding member is provided with a dust suction port, and the inside of the holding member is provided with a negative pressure chamber communicating with the dust suction port.

[0028] The suction port is positioned close to the cut of the material belt, which can effectively absorb dust generated during the cutting process under negative pressure, maintaining a clean processing environment.

[0029] According to some embodiments of this application, the cutting device further includes a negative pressure tube, one end of which is connected to the negative pressure chamber and the other end of which passes through the first bracket.

[0030] The other end of the negative pressure pipe is connected to the negative pressure supply device to enable negative pressure suction at the suction port. Furthermore, the other end of the negative pressure pipe passes through the first bracket, making efficient use of the available space. The negative pressure pipe moves synchronously with the first bracket in the second direction, improving the reliability of the connection between the negative pressure pipe and the negative pressure chamber.

[0031] According to some embodiments of this application, the cutting device further includes a heat sink, mounted on the second cutting blade, for dissipating heat from the second cutting blade.

[0032] By installing a heat sink to dissipate heat from the second cutter, the temperature of the second cutter can be reduced, thereby extending the effective service life of the second cutter.

[0033] According to some embodiments of this application, the cutting device further includes: a guide member, mounted on the second cutter, for abutting against the surface of the strip to guide the strip into the gap between the first cutter and the second cutter.

[0034] By having the guide member abut against the surface of the material strip, the feeding direction of the material strip into the gap between the first cutter and the second cutter can be guided and adjusted, so that the first cutter and the second cutter can cut the material strip stably and reliably.

[0035] A second aspect of this application also provides a method for cutting a strip of material, the method comprising:

[0036] The cutting device described in the first aspect of this application is arranged on the conveying path of the material belt;

[0037] Rotating the screw drives the adjusting member to move along the axial direction of the screw, and the adjusting member pushes the first cutter to move along the conveyor belt direction, thereby adjusting the cutter spacing of the cutter device;

[0038] The cutting device is used to cut the strip of material.

[0039] Using the cutting method in the second aspect of this application to cut the strip, the screw can be rotated to push the first cutter to move along the belt travel direction, thereby adjusting the cutter spacing of the cutting device and improving the cutting quality of the strip.

[0040] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, 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.

[0060] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0061] In this application, the term "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0062] In the description of this application, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0063] In this application, "multiple" means two or more (including two).

[0064] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, prismatic battery cells, and pouch battery cells.

[0065] A single battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrodes. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector, and the uncoated positive current collector protrudes beyond the coated one, serving as the positive electrode tab. Taking a lithium-ion battery as an example, the positive current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector, and the uncoated negative current collector protrudes beyond the coated one, serving as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon, etc. To ensure that a large current can pass through without melting, there are multiple positive electrode tabs stacked together, and there are multiple negative electrode tabs stacked together. The separator can be made of PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly can be a wound structure or a stacked structure, and the embodiments of this application are not limited to these.

[0066] In related technologies, the cutting device includes a pair of oppositely arranged cutters that together cut the electrode sheet. If the cutting quality is poor, the metal cross-section of the electrode sheet will extend along the direction of the cutter's movement when the cutter contacts the electrode sheet, forming a wire-drawing defect. When the electrode sheet is laminated with a separator, the wire-drawing of the electrode sheet may puncture the separator. When the electrode sheets are wound or stacked to form a battery cell, it may cause two layers of electrode sheets of different polarities to come into direct contact, resulting in a short circuit inside the battery cell.

[0067] The inventors discovered through research that there is a correlation between electrode thickness, cutter speed, and cutter spacing. Given a fixed electrode thickness and cutter speed, adjusting the spacing between a pair of cutters along the electrode's feeding direction can effectively avoid the aforementioned wire-drawing defects. However, most current cutter devices have low precision in adjusting the cutter spacing, and the spacing is prone to loosening after adjustment, requiring frequent adjustments. This not only makes it difficult to adjust and control the cutter spacing but also results in poor stability of the spacing after adjustment.

[0068] Based on the above ideas, this application provides a new technical solution that can effectively adjust the cutting blade spacing, and the cutting blade spacing has good stability after adjustment, which improves the cutting accuracy of the cutting device, improves the cutting accuracy of the material strip, and thus improves the cutting quality of the electrode sheet and the safety performance of the formed battery cell.

[0069] Figure 1The diagram shown is a structural schematic of the cutting device from one perspective in some embodiments of this application;

[0070] Figure 2 What is shown is Figure 1 A magnified view of a section at point A in the middle; Figure 3 What is shown is Figure 2 BB cross-section diagram.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, some embodiments of this application propose a cutting device 100.

[0072] The cutting device 100 includes a first cutter 10 and an adjusting mechanism 20, which is used to adjust the position of the first cutter 10. The adjusting mechanism 20 includes a screw 21 and an adjusting member 22. The adjusting member 22 is sleeved on the screw 21 and threadedly engaged with the screw 21. The adjusting member 22 and the first cutter 10 are wedge-shaped engaged by a pair of mating surfaces. The screw 21 is configured to rotate to drive the adjusting member 22 to move along the axial direction of the screw 21, so that the adjusting member 22 pushes the first cutter 10 to move along a first direction X, which is perpendicular to the axial direction of the screw 21.

[0073] In this embodiment, the material strip is an electrode sheet, which is used to form the cell of a battery cell. In other embodiments, the material strip can also be a composite material strip formed by laminating the electrode sheet and the separator, or it can be other forms of metal material strip or a composite material strip including a metal interlayer. The conveying direction of the material strip can be parallel to the first direction X, the thickness direction of the first cutter 10 can be parallel to the first direction X, and the cutting device 100 can cut the material strip along the width direction of the material strip; the conveying direction of the material strip can also be inclined to the first direction X, the thickness direction of the first cutter 10 can be inclined to the first direction X, and the cutting device 100 can cut the material strip along the width direction of the material strip.

[0074] Figure 4 This is a schematic diagram of the principle of the adjustment mechanism in some embodiments of this application.

[0075] like Figure 3 and Figure 4 As shown, the screw 21 includes a screw body 211 and a transmission part 212 formed at one end of the screw body 211. The transmission part 212 is used to apply external force to drive the screw 21 to rotate around its own axis. The transmission part 212 can be a nut for manual rotation, or it can be connected to the output end of a motor to achieve automated rotation.

[0076] The screw 21 extends axially along the first axis P, and the first direction X is perpendicular to the first axis P. The cutting device 100 also includes a second cutter 40 (see reference). Figure 1The second cutter 40 and the first cutter 10 are arranged opposite each other along the second direction Z, and the second cutter 40 and the first cutter 10 can approach each other along the second direction Z to cut the strip together.

[0077] The extension direction of the first axis P can be parallel to the second direction Z, and the screw 21 is arranged in the space on the side of the first cutter 10 away from the second cutter 40, exposing the transmission part 212 of the screw 21, so as to drive the screw 21 to rotate. The extension direction of the first axis P can also extend in other directions. For example, the first axis P can be perpendicular to both the second direction Z and the first direction X.

[0078] like Figure 4 As shown, the adjusting member 22 has a first mating surface 221, and the first cutter 10 has a second mating surface 112. The adjusting member 22 and the first cutter 10 are wedge-shapedly engaged through the first mating surface 221 and the second mating surface 112. When the adjusting member 22 moves along the first axis P, it can push the first cutter 10 to move along the first direction X.

[0079] Specifically, along the direction of movement of the adjusting member 22 on one side of the first axis P, the first mating surface 221 is inclined towards the direction closer to the central axis of the screw 21, and the second mating surface 112 is arranged parallel to the first mating surface 221. For example, when the first axis P extends vertically and the adjusting member 22 moves vertically downward to push the first cutter 10 to move away from the screw 21, the lower end of the first mating surface 221 is closer to the central axis of the screw 21 than the upper end; as another example, when the first axis P extends vertically and the adjusting member 22 moves vertically upward to push the first cutter 10 to move away from the screw 21, the upper end of the first mating surface 221 is closer to the central axis of the screw 21 than the lower end.

[0080] Rotating the screw 21 drives the adjusting member 22 to move axially along the screw 21. The adjusting member 22 and the first cutter 10 are engaged by a pair of wedge-shaped mating surfaces, thereby pushing the first cutter 10 to move along the first direction X. This allows adjustment of the cutting distance of the cutting device 100, improving the cutting quality of the material strip. Furthermore, the moving direction of the adjusting member 22 is perpendicular to the moving direction of the first cutter 10, making the adjusting mechanism 20 compact and space-saving, thus reducing the size and dimensions of the cutting device 100.

[0081] like Figure 4 As shown, in some embodiments of this application, the acute angle α between the axial direction (i.e., the first axis P) of the screw 21 and the mating surface is smaller than the acute angle β between the first direction X and the mating surface.

[0082] When α < β, the displacement of the adjusting member 22 along the first axis P is greater than the displacement of the first cutter 10 along the first direction X. Based on screws 21 with the same pitch, adjusting the same displacement of the first cutter 10 requires the screw 21 to rotate more times, thereby improving the displacement accuracy of the first cutter 10 and the adjustment accuracy of the cutter spacing of the cutting device 100. For example, α = 5°, β = 85°; or α = 40°, β = 50°, etc.

[0083] In other embodiments, α and β may also be equal, or α > β, to achieve a larger range of spacing adjustment.

[0084] When the screw 21 is rotated, the displacement of the adjusting member 22 is greater than the displacement of the first cutter 10. Thus, with the same displacement of the adjusting member 22, the first cutter 10 has a smaller displacement, which can improve the movement accuracy of the first cutter 10, thereby improving the spacing adjustment accuracy of the cutting device 100 and improving the cutting quality of the strip.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the adjusting mechanism 20 further includes a first elastic member 23 disposed between the screw 21 and the adjusting member 22 to tension the adjusting member 22 and the screw 21 along the axial direction (i.e., the first axis P) of the screw 21.

[0086] like Figure 3 and Figure 4 As shown, the adjustment mechanism 20 also includes a first mounting block 24 and a second mounting block 25 that are fixedly connected. The screw 21 is mounted on the second mounting block 25, and the adjustment member 22 is restricted to the first mounting block 24.

[0087] like Figure 3 As shown, the first mounting block 24 has a through hole 241 along the first axis P, and the adjusting member 22 is non-rotatably confined within the through hole 241 but can be displaced within the through hole 241 along the first axis P. The adjusting member 22 has an internal threaded hole, and the screw 21 passes through the internal threaded hole along the first axis P and is threadedly engaged with the adjusting member 22.

[0088] The second mounting block 25 is fixedly connected to the first mounting block 24 by a threaded component, and the screw 21 is rotatable around the first axis P and is fixedly mounted on the second mounting block 25 without displacement along the first axis P.

[0089] The second mounting block 25 has a slot 251 extending along the first axis P and open on one side. The slot 251 is aligned with the through hole 241 and together they form a communicating inner cavity. The screw body 211 passes through the slot 251 along the first axis P. The screw 21 also includes an annular boss 213. The annular boss 213 and the transmission part 212 abut against the second mounting block 25 from both sides along the first axis P, so as to rotatably mount the screw 21 to the second mounting block 25 around the first axis P. With this structure, the second mounting block 25 clamps one end of the screw 21, so that the screw 21 can rotate relative to the first mounting block 24 but cannot be displaced along the first axis P. It occupies little space and allows the side of the first mounting block 24 away from the second mounting block 25 to have enough space to connect with the first cutter 10.

[0090] In other embodiments, the adjustment mechanism 20 may also include two end bearing seats, which are respectively mounted on both ends of the first mounting block 24 along the first axis P, and support the screw 21 by rotating from both ends in the axial direction, so as to simplify the construction of the screw 21.

[0091] The first elastic element 23 is disposed in the communicating inner cavity formed by the slot 251 and the through hole 241. The two ends of the first elastic element 23 abut against the annular boss 213 and the adjusting element 22 respectively. Through elastic force, the internal thread of the adjusting element 22 is tightly engaged with the external thread of the screw body 211. There can be one first elastic element 23, which is sleeved on the screw body 211 to occupy less space; or there can be multiple first elastic elements 23, which are arranged circumferentially around the screw body 211. The first elastic element 23 can be a straight spring, or it can be a hydraulic push rod or a cylinder.

[0092] The first elastic element 23 tensions the adjusting element 22 and the screw 21 along the axial direction (i.e., the first axis P) of the screw 21, which can prevent the adjusting element 22 and the screw 21 from being relatively loose, causing the first cutter 10 to shake along the first direction X, resulting in a change in the cutting distance of the cutting device 100 and affecting the cutting quality of the material strip.

[0093] Figure 5 The diagram shown is a structural schematic of the first cutter in some embodiments of this application.

[0094] like Figure 5 As shown, the first cutter 10 includes a first part 11, a second part 12 and a first guide shaft (not shown in the figure). The first part 11 is used to engage with the adjusting member 22 in a wedge shape. The second part 12 forms the cutting edge 13 of the first cutter 10. The first part 11 and the second part 12 are respectively connected to the two sides of the first guide shaft along the first direction X.

[0095] Specifically, the cutting device 100 further includes a first bracket 30, a first cutter 10 which is slidably mounted on the first bracket 30 along a first direction X, and an adjustment mechanism 20 which is mounted on the first bracket 30. The length direction of both the first bracket 30 and the first cutter 10 extends along a third direction Y, which is perpendicular to the first direction X.

[0096] Please refer to Figure 3 , Figure 4 and Figure 5 In the specific embodiment described above, "the adjustment mechanism 20 further includes a first mounting block 24 and a second mounting block 25 that are fixedly connected, the screw 21 is mounted on the second mounting block 25, and the adjustment member 22 is restricted to the first mounting block 24", one end of the first mounting block 24 is mounted on the first bracket 30 along the first direction X, and the other end is set on the same side as the first part 11.

[0097] like Figure 5 As shown, in some embodiments of this application, the first part 11 and the second part 12 are respectively disposed on both sides of the first bracket 30 along the first direction X. Multiple first guide shafts are provided, and the first bracket 30 is provided with multiple first guide holes extending along the first direction X. Each first guide shaft corresponds to one of the first guide holes, and the first guide shaft passes through the corresponding first guide hole. This structural form allows the first cutter 10 to move along the first direction X based on the first bracket 30 to adjust the cutter spacing, and also reduces the overall external dimensions of the first cutter 10 and the first bracket 30 along the first direction X, making the cutter device 100 structurally compact.

[0098] In other embodiments, the first cutter 10 may also be located on one side of the first support 30 along the first direction X to simplify the construction of the first cutter 10.

[0099] The first part 11 and the adjusting member 22 of the adjusting mechanism 20 are engaged by a pair of mating surfaces in a wedge shape. The adjusting member 22 moves along the first axis P to push the first part 11 to move along one side of the first direction X.

[0100] like Figure 5 As shown, two adjustment mechanisms 20 can be provided, spaced apart along the length of the first cutter 10. When there is a clearance between the first guide shaft and the first bracket 30, the two adjustment mechanisms 20 can be used to adjust the position of the first cutter 10 at two points along its length, improving the displacement accuracy of the first cutter 10 and thus improving the cutting distance adjustment accuracy of the cutting device 100. Alternatively, only one adjustment mechanism 20 can be provided, centrally located along the length of the first cutter 10.

[0101] The blade 13 can be a separate component, and the blade 13 can be fixedly connected to the second part 12 by a threaded part; the blade 13 can also be integrally formed with the second part 12 and connected to one end of the first guide shaft.

[0102] Figure 6 The diagram shown is a structural schematic of the cutting device from another perspective in some embodiments of this application; Figure 7 What is shown is Figure 6 A magnified view of a section at point C; Figure 8 What is shown is Figure 7 DD cross-section view.

[0103] like Figure 6 and Figure 7 As shown, the first part 11 may also be provided with a plurality of weight-reducing grooves 14 to reduce the weight of the first cutter 10 and make the first cutter 10 easier to move along the first direction X.

[0104] The blade 13 of the first cutter 10 and the mating surface that engages with the wedge-shaped adjustment member 22 are respectively formed on both sides of the first cutter 10 along the first direction X. This can maximize the distance between the blade 13 and the mating surface, and the vibration generated by the blade 13 can be effectively dissipated during transmission to the adjustment mechanism 20, thereby reducing the vibration amplitude of the adjustment mechanism 20. This also prevents the adjustment mechanism 20 from becoming loose during use, which would cause changes in the cutter spacing and affect the cutting quality of the strip.

[0105] like Figure 6 , Figure 7 and Figure 8 As shown, the adjustment mechanism 20 includes two screws 21 and two adjusting members 22. The screws 21 and the adjusting members 22 are correspondingly arranged. The two adjusting members 22 are respectively arranged on the first side X1 and the second side X2 opposite to each other along the first direction X of the first part 11, and are wedge-shaped with the first part 11. One of the two adjusting members 22 is configured to push the first cutter 10 to move along the first direction X toward the first side X1, and the other of the two adjusting members 22 is configured to push the first cutter 10 to move along the first direction X toward the second side X2 opposite to the first side X1.

[0106] like Figure 8As shown, specifically, a screw and a corresponding adjusting member together constitute an adjusting assembly. The adjusting mechanism 20 includes a first adjusting assembly 26 and a second adjusting assembly 27. Two opposite sides in the first direction X are defined as the first side X1 and the second side X2, respectively. Based on the aforementioned, the first adjusting assembly 26 is used to push the first part 11 to move along the first side X1 in the first direction X, and the second adjusting assembly 27 is used to push the first part 11 to move along the second side X2 in the first direction X. When rotating the screw 21 of the first adjusting assembly 26 drives the corresponding adjusting member 22 to move towards the first side X1, the adjusting member 22 of the second adjusting assembly 27 passively moves towards the first side X1; when rotating the screw 21 of the second adjusting assembly 27 drives the corresponding adjusting member 22 to move towards the second side X2, the adjusting member 22 of the first adjusting assembly 26 passively moves towards the second side X2.

[0107] like Figure 8 As shown, based on the aforementioned embodiment where "the adjustment mechanism 20 further includes a first mounting block 24 and a second mounting block 25 fixedly connected, the screw 21 is mounted on the second mounting block 25, and the adjustment member 22 is restricted to the first mounting block 24", the first adjustment component 26 and the second adjustment component 27 can be jointly mounted on the same first mounting block 24, and each adjustment component has a second mounting block 25. The first adjustment component 26 and the second adjustment component 27 are arranged opposite to each other along the first direction X.

[0108] In other embodiments, the first adjustment component 26 and the second adjustment component 27 may also have a first mounting block 24 and a second mounting block 25, respectively, and the first adjustment component 26 and the second adjustment component 27 are arranged at intervals along the third direction Y.

[0109] like Figure 8 As shown, based on the above-mentioned embodiment in which "the first adjustment component 26 and the second adjustment component 27 can be installed together on the same first mounting block 24", the first part 11 is provided with a narrow part 111, and the two sides of the narrow part 111 along the first direction X each have a second mating surface 112, and the two second mating surfaces 112 are arranged opposite to each other.

[0110] By setting the first adjustment component 26 and the second adjustment component 27, the position of the first cutter 10 can be precisely adjusted on both opposite sides along the first direction X, thereby controlling the increase or decrease of the cutter spacing of the cutter device.

[0111] In some embodiments of this application, the first direction X is parallel to the thickness direction of the first cutter 10.

[0112] Specifically, the thickness direction of the first cutter 10 extends along the first direction X, the length direction extends along the third direction Y, and the width direction extends along the second direction Z.

[0113] In other embodiments, the first direction X may also be inclined to the thickness direction of the first cutter 10. For example, the angle between the length direction of the first cutter 10 and the third direction Y is 45°, the thickness direction of the first cutter 10 is perpendicular to the length direction of the first cutter 10, and the width direction of the first cutter 10 extends along the second direction Z, etc.

[0114] The first cutter 10 is pushed to move along its thickness direction to adjust the cutting distance of the cutting device 100. This not only facilitates the calculation of the adjustment amount of the cutting distance, but also allows for a larger adjustment of the cutting distance with a small displacement of the first cutter 10, thus achieving high distance adjustment accuracy.

[0115] like Figure 6 and Figure 7 As shown, the cutting device 100 also includes a second cutter 40 and a drive assembly 50. The drive assembly 50 is configured to drive the first cutter 10 and the second cutter 40 to move relative to each other along a second direction Z, so that the first cutter 10 and the second cutter 40 jointly cut the strip, the second direction Z being perpendicular to the first direction X.

[0116] In some embodiments of this application, the second direction Z extends vertically, the second cutter 40 is located on the lower side, and the first cutter 10 is located on the upper side. The first cutter 10 and the second cutter 40 are a pair of cutters facing each other vertically. In other embodiments, the second direction Z may also extend horizontally or in other directions, or the first cutter 10 may be located on the lower side.

[0117] The first cutter 10 and the second cutter 40 are arranged opposite each other along the second direction Z. When the first cutter 10 and the second cutter 40 approach each other along the second direction Z, they can cut the material strip together. The first cutter 10 and the second cutter 40 are staggered in the first direction X. The distance between the first cutter 10 and the second cutter 40 along the first direction X is defined as the cutting distance of the cutting device 100.

[0118] The second cutter 40 can be a regular cutter or an ultrasonic cutter.

[0119] The drive assembly 50 can drive the first cutter 10 and the second cutter 40 to move relative to each other along the second direction Z in various ways. For example, one of the first cutter 10 and the second cutter 40 is fixed, while the other moves closer to or away from the second cutter 40 along the second direction Z; or, for another example, both the first cutter 10 and the second cutter 40 are displaced, and the first cutter 10 and the second cutter 40 simultaneously move closer to each other along the second direction Z to cut the strip.

[0120] Adjusting the first cutter 10 to move closer to or further away from the second cutter 40 along the first direction X can effectively adjust the cutting distance of the cutting device 100.

[0121] like Figure 6 and Figure 7 As shown, the cutting device 100 also includes a first bracket 30 and a second bracket 60. The first bracket 30 and the second bracket 60 are slidably engaged along the second direction Z. The first cutter 10 is mounted on the first bracket 30, and the second cutter 40 is mounted on the second bracket 60.

[0122] The first bracket 30 and the second bracket 60 can slide together via a guide rail assembly or via multiple guide shafts.

[0123] Figure 9 The diagram shown is a schematic diagram of the assembly structure of the first support and the second support in some embodiments of this application.

[0124] like Figure 6 and Figure 9 As shown, the first bracket 30 and the second bracket 60 may be provided with a guide sleeve assembly 90. The guide sleeve assembly 90 abuts against the third part 31 of the first bracket 30 and the second bracket 60 along the second direction Z to buffer the impulse generated during the relative movement of the first bracket 30 and the second bracket 60.

[0125] Specifically, the guide sleeve assembly 90 includes a first sleeve 91, a second sleeve 92, and a third elastic element (not shown in the figure). The first sleeve 91 is fixed to the second bracket 60, and the second sleeve 92 is fixed to the third part 31. The first sleeve 91 is sleeved on the second sleeve 92, and the first sleeve 91 and the second sleeve 92 are slidably engaged along the second direction Z. The third elastic element is disposed in the inner cavity between the first sleeve 91 and the second sleeve 92, and both ends of the third elastic element abut against the first sleeve 91 and the second sleeve 92, respectively. As a preferred embodiment, a magnetic element 93 is provided between the first sleeve 91 and the second sleeve 92 to magnetically attract metal dust generated during the cutting process, maintaining a clean processing environment.

[0126] One of the first bracket 30 and the second bracket 60 is fixed, while the other is movable. The drive component 50 is installed on the fixed bracket of the first bracket 30 and the second bracket 60, and the output end of the drive component 50 is connected to the movable bracket. Alternatively, the first bracket 30 and the second bracket 60 can both be slidably installed on another fixed bracket. There are two drive components 50, both of which are installed on the fixed bracket. One drive component 50 is used to drive the first bracket 30 to move, and the other drive component 50 is used to drive the second bracket 60 to move.

[0127] The first bracket 30 and the second bracket 60 can be spaced apart along the second direction Z, or one of the first bracket 30 and the second bracket 60 can be located between the other along the second direction Z.

[0128] The first support 30 and the second support 60 slide together along the second direction Z, which can guide the first cutter 10 and the second cutter 40 to move closer or further apart along the second direction Z, making the cutting process stable and reliable.

[0129] Figure 10 The diagram shown is a schematic diagram of the assembly structure of the first bracket and the drive assembly in some embodiments of this application.

[0130] like Figure 6 and Figure 10 As shown, in some embodiments of this application, the first bracket 30 includes a third part 31, a fourth part 32, and a second guide shaft 33. The third part 31 and the fourth part 32 are located on opposite sides of the second bracket 60 along the second direction Z. The second guide shaft 33 extends along the second direction Z and is slidably inserted through the second bracket 60. The second guide shaft 33 connects the third part 31 and the fourth part 32. The first cutter 10 and the adjustment mechanism 20 are mounted on the third part 31, and the drive assembly 50 is mounted on the second bracket 60 and connected to the fourth part 32.

[0131] As a further explanation of the above-described embodiment where "one of the first support 30 and the second support 60 is located between the other along the second direction Z," the second support 60 is disposed along the second direction Z between the third portion 31 and the fourth portion 32 of the first support 30. Four second guide shafts 33 are provided, spaced apart around the second cutter 40 fixed on the second support 60. The second support 60 has second guide holes corresponding to the second guide shafts 33, and each second guide shaft 33 passes through the corresponding second guide hole along the second direction Z. The third portion 31 and the fourth portion 32 are located on both sides of the second support 60 along the second direction Z, and the third portion 31, the fourth portion 32, and the second guide shaft 33 form an integral structure.

[0132] Based on the aforementioned specific embodiment where "the second direction Z extends vertically, the second cutter 40 is located on the lower side, and the first cutter 10 is located on the upper side," the third part 31 is located on the upper side of the second bracket 60 and is equipped with the first cutter 10 and the adjustment mechanism 20. The fourth part 32 is located on the lower side of the second bracket 60, and the drive assembly 50 is installed on the lower side of the second bracket 60. The output end of the drive assembly 50 is connected to the fourth part 32. By driving the fourth part 32 to reciprocate along the second direction Z, the second cutter 40 moves closer to or further away from the first cutter 10 to perform the cutting action. In other embodiments, the third part 31 and the fourth part 32 may also be located on opposite sides of a certain horizontal direction of the second bracket 60.

[0133] The third part 31 is provided with a first guide hole extending along the first direction X, and the first guide shaft of the first cutter 10 passes through the first guide hole to slide in cooperation with the third part 31 along the first direction X. The fourth part 32 is provided with a connecting shaft 321 to connect to the output end of the drive assembly 50.

[0134] The third part 31 is equipped with the first cutter 10 and the adjustment mechanism 20. The fourth part cooperates with the drive assembly 50. The third part 31 and the fourth part 32 are located on both sides of the second bracket 60 along the second direction Z, which enables the drive assembly 50 to be located on one side of the second bracket 60 and the first cutter 10 and the adjustment mechanism 20 to be located on the other side of the second bracket 60. The positions of the first cutter 10, the adjustment mechanism 20 and the drive assembly 50 are reasonably arranged, making the cutter device 100 compact in structure and small in size.

[0135] Figure 11 The diagram shown is a schematic representation of the structure of the driving component in some embodiments of this application.

[0136] like Figure 10 and Figure 11 As shown, the drive assembly 50 includes a drive member 51, a first connector 52, and a second connector 53. The drive member 51 is mounted on the second bracket 60. One end of the first connector 52 is connected to the output shaft of the drive member 51. One end of the second connector 53 is rotatably connected to the other end of the first connector 52, and the other end of the second connector 53 is rotatably connected to the first bracket 30, so that the drive member 51 can drive the first bracket 30 to reciprocate relative to the second bracket 60 through the first connector 52 and the second connector 53.

[0137] Specifically, the drive assembly 50 also includes a third bracket 54, a coupling 55, and a drive shaft 56. The third bracket 54 is mounted on the lower side of the second bracket 60. The drive component 51 is a motor, which is connected to the drive shaft 56 via the coupling 55. The first connecting component 52 is an eccentric wheel, which is eccentrically mounted on the drive shaft 56. The second connecting component 53 is provided with two bearings: one bearing rotates with the eccentric wheel, and the other bearing is connected to the connecting shaft 321 of the fourth part 32 of the first bracket 30 (see reference). Figure 11 Rotational engagement. The eccentric wheel engages with the second connecting member 53, resulting in a large contact area between the first connecting member 52 and the second connecting member 53, ensuring stable and reliable transmission. The first connecting member 52 and the second connecting member 53 can also be a two-bar linkage mechanism, with one end hinged to the transmission shaft 56 and the other end rotatably engaged with the connecting shaft of the fourth part 32.

[0138] In other embodiments, the drive component 50 may also be a common linear drive component, such as a linear cylinder, a hydraulic push rod, etc.

[0139] The drive component 51 drives the first bracket 30 to move along the second direction Z in a rotating manner through the first connector 52 and the second connector 53. This enables the first bracket 30 to reciprocate at high speed along the second direction Z, while minimizing the impact on the second bracket 60 and alleviating the vibration of the cutter device 100 under high-speed cutting conditions.

[0140] Figure 12 The diagram shown is a schematic representation of the assembly structure of the second part of the first cutter and the pressure member in some embodiments of this application; Figure 13 for Figure 12 A magnified view of a section at point E in the middle.

[0141] like Figure 10 and Figure 12 As shown, the cutting device 100 also includes a holding assembly 70, which includes a holding member 71 and a second elastic member 72. The holding member 71 is movably mounted on the first cutter 10 along the second direction Z and is used to hold the surface of the strip to be cut. The second elastic member 72 is disposed between the first cutter 10 and the holding member 71.

[0142] like Figure 12 and Figure 13 As shown, the clamping member 71 has a clamping surface 712, which is used to abut against the surface of the strip to be cut to clamp it onto the strip surface. The clamping member 71 and the second cutter 40 can be aligned. The clamping member 71 clamps the strip onto the second cutter 40, so that the clamping member 71 and the second cutter 40 together clamp the strip along the second direction Z. The first cutter 10 moves along the second direction Z to cut the strip, thereby positioning and clamping the strip to prevent the strip from shaking when subjected to cutting impact, which would affect the cutting quality. Alternatively, the clamping member 71 can be offset from the second cutter 40 along the first direction X, with another abutting block provided to align with the clamping member 71. The clamping member 71 and the abutting block together clamp the strip.

[0143] The clamping assembly 70 also includes a fourth guide shaft 73, which passes through the second portion 12 of the first cutter 10 and the clamping member 71 along the second direction Z to restrict relative movement of the clamping member 71 along the second direction Z. The fourth guide shaft 73 can be a threaded member, passing through the second portion 12 along the second direction Z and slidingly engaging with it. The end of the threaded member is inserted into the clamping member 71 and threadedly engaged with it. Alternatively, the fourth guide shaft 73 can be riveted to connect the clamping member 71 to the second portion 12, allowing relative movement between the clamping member 71 and the second portion 12 along the second direction Z.

[0144] Multiple fourth guide axes 73 can be provided, with multiple fourth guide axes 73 spaced apart along the third direction Y; or there can be only one fourth guide axis 73 centered along the third direction Y.

[0145] The second elastic element 72 can be sleeved on the fourth guide shaft 73. The two ends of the second elastic element 72 abut against the pressing element 71 and the second part 12 respectively. The number and arrangement of the second elastic elements 72 correspond one-to-one with the fourth guide shaft 73. The second elastic element 72 can also be set independently of the fourth guide shaft 73.

[0146] The second elastic element 72 can be a straight spring, a gas spring, or an elastic rubber component.

[0147] When the first cutter 10 and the second cutter 40 approach each other, the holding member 71 presses against the surface of the strip, and the second elastic member 72 is compressed to allow the first cutter 10 to continue to approach the second cutter 40 along the second direction Z to cut the strip. The holding member 71 also elastically holds the strip, positioning it during the cutting process to ensure stable and reliable cutting.

[0148] like Figure 12 and Figure 13 As shown, the holding member 71 is provided with a dust suction port 711, and the inside of the holding member 71 is provided with a negative pressure chamber that communicates with the dust suction port 711 (not shown in the figure).

[0149] Specifically, the holding member 71 and the blade 13 of the first cutter 10 are spaced apart along the first direction X (e.g., Figure 10 As shown, the holding member 71 has a dust-collecting side (not shown in the figure) and a connecting side (not shown in the figure) on both sides along the first direction X. The dust-collecting side is close to the blade 13 and is used to absorb dust generated during the cutting process. The connecting side is used to connect with the negative pressure providing device. The negative pressure chamber is disposed inside the holding member 71. The negative pressure chamber is connected to the dust-collecting port 711 on the dust-collecting side and has a negative pressure interface on the connecting side.

[0150] Multiple suction ports 711 can be provided, and the multiple suction ports 711 are spaced apart along the third direction Y; the suction ports 711 can also be narrow openings extending along the third direction Y.

[0151] There can be one negative pressure chamber, and multiple suction ports 711 are connected to the same negative pressure chamber; or there can be multiple negative pressure chambers, which are spaced apart along the third direction Y. The multiple suction ports 711 spaced apart along the third direction Y are divided into multiple suction units. Each suction unit includes multiple suction ports 711 arranged in a continuous manner, and the multiple suction ports 711 of the same suction unit correspond to one negative pressure chamber.

[0152] The suction port 711 is located near the cut of the material belt, which can effectively adsorb the dust generated during the cutting process under negative pressure and maintain a clean processing environment.

[0153] like Figure 12 and Figure 13As shown, the cutting device 100 also includes a negative pressure tube 74, one end of which is connected to the negative pressure chamber and the other end of which passes through the first bracket 30.

[0154] One end of the negative pressure tube 74 is connected to the negative pressure cavity on the connecting side of the pressure holder 71, and the other end passes through the third part 31 of the first bracket 30 in the direction away from the second bracket 60 along the second direction Z. The third part 31 is provided with an oblong hole 311, which passes through the third part 31 in the second direction Z and extends in the first direction X, so as to allow the negative pressure tube 74 to move synchronously when the first cutter 10 is displaced in the first direction X.

[0155] The negative pressure tube 74 can also be directly connected to the negative pressure supply device on the connection side of the pressure holding member 71, without penetrating the first bracket 30.

[0156] The number of negative pressure tubes 74 corresponds one-to-one with the number of negative pressure chambers. For example, when there are three negative pressure chambers, there are also three negative pressure tubes 74, and three oblong holes 311 in the third part 31 are also provided. Each negative pressure tube 74 is connected to the corresponding negative pressure chamber and passes through the corresponding oblong hole 311 to connect with the negative pressure supply device.

[0157] The other end of the negative pressure pipe 74 is connected to the negative pressure supply device so that the suction port 711 can suck up dust under negative pressure. The other end of the negative pressure pipe 74 passes through the first bracket 30, making reasonable use of the arrangement space. The negative pressure pipe 74 moves synchronously with the first bracket 30 along the second direction Z, which improves the reliability of the connection between the negative pressure pipe 74 and the negative pressure chamber.

[0158] Figure 14 The diagram shown is a schematic representation of the assembly structure of the second cutter and the second cutter accessory assembly in some embodiments of this application.

[0159] like Figure 1 and Figure 14 As shown, the cutting device 100 also includes a second cutting accessory assembly, which includes a heat sink 81 mounted on the second cutting blade 40 for heat dissipation of the second cutting blade 40.

[0160] When the second cutter 40 is an ultrasonic cutter, the vibration generated during the cutting process and the friction with the material strip during the cutting process will cause the temperature of the second cutter 40 to rise. The second cutter 40 will maintain a high temperature for a long time, which will affect the structural strength of the second cutter 40 and thus reduce the service life of the second cutter 40.

[0161] Multiple heat sinks 81 can be provided, and the multiple heat sinks 81 are spaced apart along the third direction Y; or there can be a single heat sink 81, which is a long strip extending along the third direction Y.

[0162] The heat sink 81 can be a semiconductor cooling plate, using the thermocouple principle to actively dissipate heat from the second cutter 40; the heat sink 81 can also be a heat sink fin, increasing the heat dissipation area to dissipate heat from the second cutter 40. The heat sink 81 can be bonded to the surface of the second cutter 40 with thermally conductive adhesive, or it can be abutted against the surface of the second cutter 40 by other connecting parts.

[0163] The heat sink 81 can be disposed on one side of the second cutter 40 along its thickness direction, or on both sides of the second cutter 40 along its thickness direction.

[0164] By setting up a heat sink 81 to dissipate heat from the second cutter 40, the temperature of the second cutter 40 can be reduced, thereby extending the effective service life of the second cutter 40.

[0165] like Figure 6 and Figure 14 As shown, the cutting device 100 also includes a second cutting accessory assembly, which includes a guide 82 mounted on the second cutter 40 for contacting the surface of the material strip to guide the material strip into the gap between the first cutter 10 and the second cutter 40.

[0166] The guide member 82 is disposed on the feeding side of the second cutter 40. The guide member 82 abuts against the surface of the material strip to guide the material strip's feeding direction, so that the material strip enters the gap between the first cutter 10 and the second cutter 40 along the first direction X, so as to cut the material strip along the thickness direction and improve the cutting quality of the material strip.

[0167] In the above-described embodiment of "heat sink 81 installed on the second cutter 40", the heat sink 81 and the guide 82 are respectively arranged on both sides of the second cutter 40 along the first direction X. The guide 82 is disposed on the feeding side of the second cutter 40, and the heat sink 81 is disposed on the discharge side of the second cutter 40, so as to make reasonable use of the space on both sides of the second cutter 40.

[0168] The guide 82 can be directly fixed to the second cutter 40, or it can be fixed to the second bracket 60 and abut against the second cutter 40.

[0169] like Figure 14 As shown, in some embodiments of this application, the guide member 82 includes a guide portion 821 and a first mounting portion 822 and a second mounting portion 823 connected to both ends of the guide portion 821. The first mounting portion 822 is used to abut against the surface of the second cutter 40, and the second mounting portion 823 is used to be threaded onto the second bracket 60 (see reference). Figure 6 The surface of the guide section 821 is curved and is used to abut against the surface of the strip to guide the gap between the first cutter 10 and the second cutter 40.

[0170] By having the guide member 82 abut against the surface of the material strip, the feeding direction of the material strip into the gap between the first cutter 10 and the second cutter 40 can be guided and adjusted, so that the first cutter 10 and the second cutter 40 can stably and reliably cut the material strip.

[0171] Figure 15 The diagram shows a flowchart of a method for cutting a strip according to some embodiments of this application.

[0172] like Figure 15 As shown, some embodiments of this application also propose a method for cutting a strip of material, the method comprising:

[0173] S1: A cutting device 100 is arranged on the conveying path of the material belt;

[0174] S2: Rotate screw 21 to drive adjustment member 22 to move along the axial direction of screw 21 (i.e., the first axis P), and push the first cutter 10 to move along the conveyor belt direction through adjustment member 22 to adjust the cutting distance of the cutter device 100.

[0175] S3: Use a cutting device 100 to cut the strip.

[0176] It is understood that the material strip can be conveyed horizontally, vertically, or in other directions. In the above-described embodiment where "the adjusting mechanism 20 includes two screws 21 and two adjusting members 22", rotating the two screws 21 respectively adjusts the cutter spacing to increase or decrease.

[0177] The appropriate cutting blade spacing is determined by analyzing the thickness of the strip and the rotation speed of the drive component 51 in the drive assembly 50. The cutting blade spacing is adjusted using the adjustment mechanism 20 to avoid stringing defects at the cut when cutting the strip.

[0178] Using the cutting method in this embodiment to cut the strip, the screw 21 can be rotated to push the first cutter 10 to move along the strip's travel direction, thereby adjusting the cutting distance of the cutter device 100 and improving the cutting quality of the strip.

[0179] like Figures 1-15As shown, some embodiments of this application also propose a cutting device 100, including a first cutter 10, an adjusting mechanism 20, a first bracket 30, a second cutter 40, a driving assembly 50, a second bracket 60, a holding member 71, a heat sink 81, and a guide member 82. The first cutter 10 is mounted on the first bracket 30, and the second cutter 40 is mounted on the second bracket 60. The first bracket 30 is slidably mounted on the second bracket 60 in the vertical direction. The first cutter 10 and the second cutter 40 are arranged vertically opposite each other, with the second cutter 40 located below the first cutter 10. The second cutter 40 is a fixed cutter, and the first cutter 10 is a movable cutter. The driving assembly 50 is mounted on the second bracket 60 and can drive the first bracket 30 to reciprocate in the vertical direction, thereby driving the first cutter 10 to move synchronously. The first cutter 10 and the second cutter 40 jointly cut the material strip.

[0180] Before using the cutting device 100 to cut the strip, the cutting distance of the cutting device 100 needs to be adjusted. The specific adjustment process is as follows:

[0181] The second cutter 40 is fixed to the second bracket 60;

[0182] Tightening screw 21 causes it to rotate and lower adjusting member 22. Adjusting member 22 engages with the first part 11 of the first cutter 10 in a wedge shape. As adjusting member 22 descends, it pushes the first cutter 10 along the first direction X through a pair of mating surfaces, thus reducing the cutter spacing. The first elastic member 23 abuts against the screw 21 and adjusting member 22 to prevent loosening. Alternatively, tightening another screw 21 lowers the corresponding adjusting member 22, increasing the cutter spacing. The spacing between the second cutter 40 and the first cutter 10 along the first direction X is checked. When the spacing meets the requirements, the cutting device 100 is successfully adjusted. The adjusted cutting device 100 effectively prevents stringing defects at the cut edge of the material strip during the cutting process.

[0183] The process of cutting the strip using the cutting device 100 is as follows:

[0184] The electrode travels along the conveying path and is guided by the guide 82 into the gap between the first cutter 10 and the second cutter 40. The second cutter 40 vibrates under the action of the ultrasonic generator. The drive 51 drives the eccentric wheel to rotate, so as to drive the first cutter 10 to descend through the connecting rod. The holding member 71 descends to press the material strip onto the upper surface of the second cutter 40. The first cutter 10 continues to descend, and the blade 13 works in conjunction with the high-frequency vibration of the second cutter 40 to cut the material strip. A semiconductor cooling plate is attached to the surface of the second cutter 40 to reduce the temperature of the second cutter 40.

[0185] During the cutting of the strip, the first cutter 10 reciprocates via a motor and a cam linkage assembly. After reaching its lower limit, the first cutter 10 immediately returns vertically upwards, enabling high-frequency reciprocating motion and thus high-frequency cutting operations. Dust is adsorbed by the negative pressure of the suction port 711 on the holding member 71, and metallic dust is adsorbed by the magnetic component 93 mounted on the guide sleeve assembly 90. This allows for dust removal from both the inside and outside of the cutting device 100, maintaining a clean processing environment.

[0186] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0187] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
