Description

Technical Field

[0001] This application relates to the field of copper foil slitting technology, and more particularly to a material slitting apparatus. Background Technology

[0002] Copper foil with a thickness of 105μm and above is widely used in high-density interconnects, multilayer boards and high-frequency circuits (such as 5G base stations and satellite communications) due to its excellent conductivity, bending resistance and thermal stability.

[0003] In related technologies, copper foil slitting equipment usually has a blade gap adjustment system. During operation, the gap between the blade and the lower blade roller is adjusted manually or semi-automatically to accommodate copper foil of different thicknesses for slitting.

[0004] However, due to the influence of assembly dimensions or the increase in the working time of the slitting equipment, the cutting tools are prone to slight deflection or offset. At this time, it is difficult to adjust the cutting tool to the optimal working position by relying solely on single-dimensional blade gap adjustment, which in turn affects the subsequent slitting accuracy of the copper foil and easily leads to a high amount of copper powder generation, resulting in serious copper powder contamination. Summary of the Invention

[0005] This application provides a material slitting device to solve the problem that slitting equipment in related technologies is difficult to maintain good slitting accuracy and is prone to producing a high amount of copper powder.

[0006] This application provides a material cutting device, comprising:

[0008] Mounting base, which is movably mounted on the mounting rail;

[0009] A first connecting seat is movably disposed on the mounting base;

[0012] The cutting tool is used to cut material; the mounting base is movable relative to the mounting track to adjust the cutting angle of the cutting tool; the first connecting seat is movable relative to the mounting base to adjust the cutting gap of the cutting tool; the second connecting seat is movable relative to the first connecting seat to adjust the elevation angle of the cutting tool.

[0013] In one possible implementation, the mounting track extends horizontally, the mounting base is slidably disposed on the mounting track in a horizontal direction, and the mounting base can also rotate relative to the mounting track about a vertical axis of rotation.

[0014] The first connecting seat is slidably mounted on the mounting base in the vertical direction;

[0015] The second connecting seat is rotatably mounted on the first connecting seat about a horizontal axis of rotation.

[0016] In one possible implementation, at least two mounting tracks are provided and are parallel to each other. The mounting base includes a support beam and at least two sliders. The support beam is connected to each of the sliders. The sliders are correspondingly sleeved on the mounting tracks so that the sliders are slidably connected to the mounting tracks. There is a gap between the side of the mounting track and the side of the slider so that the slider can rotate relative to the mounting track about a vertical axis of rotation.

[0017] The first connecting seat is slidably mounted on the support beam in the vertical direction.

[0018] In one possible implementation, the mounting track is provided with a rack portion, the extending direction of the rack portion being consistent with the extending direction of the mounting track;

[0019] The slider is provided with a first driving member and a gear, the gear meshing with the rack portion, and the first driving member is used to control the rotation or stop the rotation of the gear.

[0020] In one possible implementation, a lead screw is rotatably mounted on the mounting base, the lead screw is threaded to the first connecting seat, and the extension direction of the lead screw is consistent with the sliding direction of the first connecting seat;

[0021] A second driving component is provided on the mounting base, which is used to control the rotation or stop the rotation of the lead screw.

[0022] In one possible implementation, a pressure detection element is further included. The pressure detection element is used to detect the pressure on the cutting tool. The pressure detection element is electrically connected to the second driving element. The second driving element is used to control the lead screw to rotate or stop rotating according to the pressure, so as to dynamically adjust the tool gap and keep the pressure within a preset range.

[0023] In one possible implementation, a third driving member is also included, wherein the second connecting seat is rotatably connected to the first connecting seat via an elevation angle shaft, and the third driving member is used to drive the elevation angle shaft to rotate or stop rotating.

[0024] In one possible implementation, a spindle is slidably mounted on the second connecting seat, the tool is rotatably mounted on the spindle, and a fine-tuning component is provided on the second connecting seat for controlling the spindle to slide or stop sliding relative to the second connecting seat.

[0025] In one possible implementation, the fine-tuning component includes a fine-tuning nut, which is sleeved and threadedly connected to the main shaft, and the fine-tuning nut is rotatably connected to the second connecting seat.

Therefore, when slitting copper foil, if the cutting tool experiences slight offset or deflection due to prolonged use or dimensional deviations in assembly, the movement of the mounting base, the first connecting seat, and / or the second connecting seat can be controlled to perform three-dimensional coordinated adjustment of the cutting tool's separation angle, elevation angle, and / or clearance. This facilitates adjusting the cutting tool to an optimal working position, maintaining better slitting accuracy for the copper foil, and also adapting to copper foil slitting operations with higher precision requirements. When the cutting tool is adjusted to the optimal working position, the gap between the cutting tool and the copper foil can be optimized, thereby greatly reducing the amount of copper powder generated and the possibility of edge burrs on the copper foil, and improving the copper foil slitting quality. This solves the problem in related technologies where slitting equipment is difficult to maintain optimal slitting accuracy and easily leads to a high amount of copper powder generated.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] In related technologies, copper foil with a thickness of 105μm and above is widely used in high-density interconnects, multilayer boards and high-frequency circuits (such as 5G base stations and satellite communications) due to its excellent conductivity, bending resistance and thermal stability.

[0047] Copper foil slitting equipment typically has a blade gap adjustment system. During operation, the gap between the blade and the lower blade roller is adjusted manually or semi-automatically to accommodate copper foil of different thicknesses for slitting.

[0048] However, due to the influence of assembly dimensions or the increase in the working time of the slitting equipment, the cutting tools are prone to slight deflection or offset, which affects the accuracy of subsequent copper foil slitting and easily leads to a high amount of copper powder (i.e., debris scattered during copper foil slitting), resulting in serious copper powder contamination. In other words, when the cutting tools experience slight offset or deflection due to prolonged use or deviations in assembly dimensions, the slitting equipment, which can only achieve single-dimensional blade gap adjustment, finds it difficult to adjust the cutting tools to the optimal working position, thus affecting the accuracy of subsequent copper foil slitting (e.g., large deviations in the width of the slitting copper foil, inclined surfaces at the cut edges, etc.), and the high amount of copper powder generated makes the edges of the slitting copper foil prone to burrs.

[0049] Based on this, this application provides a material slitting device, including: a mounting track; a mounting base movably disposed on the mounting track; a first connecting seat movably disposed on the mounting base; a second connecting seat movably disposed on the first connecting seat; a cutting tool disposed on the second connecting seat; the cutting tool is used to slit materials; the mounting base is movable relative to the mounting track to adjust the cutting tool's separation angle; the first connecting seat is movable relative to the mounting base to adjust the cutting tool's clearance; and the second connecting seat is movable relative to the first connecting seat to adjust the cutting tool's elevation angle. Therefore, when slitting copper foil, if the cutting tool experiences slight offset or deflection due to prolonged use or dimensional deviations in assembly, the movement of the mounting base, the first connecting seat, and / or the second connecting seat can be controlled to perform three-dimensional coordinated adjustment of the cutting tool's separation angle, elevation angle, and / or clearance. This facilitates adjusting the cutting tool to an optimal working position, maintaining better slitting accuracy for the copper foil, and also adapting to copper foil slitting operations with higher precision requirements. When the cutting tool is adjusted to the optimal working position, the gap between the cutting tool and the copper foil can be optimized, thereby greatly reducing the amount of copper powder generated and the possibility of edge burrs on the copper foil, and improving the copper foil slitting quality. This solves the problem in related technologies where slitting equipment is difficult to maintain optimal slitting accuracy and easily leads to a high amount of copper powder generated.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, a material slitting device is provided, which can be used to slitting copper foil, metal plates, fabrics, or other materials. In this embodiment, copper foil slitting is taken as an example. The material slitting device includes:

[0052] Install track 100;

[0053] Mounting base 200, which is movably mounted on mounting rail 100;

[0054] The first connecting seat 300 is movably mounted on the mounting base 200;

[0055] The second connector 400 is movably mounted on the first connector 300.

[0056] Cutting tool 500 is mounted on the second connecting seat 400;

[0057] The blade 500 is used to cut materials; the mounting base 200 is movable relative to the mounting rail 100 to adjust the separation angle of the blade 500; the first connecting seat 300 is movable relative to the mounting base 200 to adjust the blade gap of the blade 500; the second connecting seat 400 is movable relative to the first connecting seat 300 to adjust the elevation angle of the blade 500.

[0058] It should be noted that the cutter 500 is vertically mounted on the second connecting seat 400 and can be rotatably connected to the second connecting seat 400. The material slitting device may also include a lower cutter roller 600 for continuously conveying the copper foil forward, with the cutter 500 positioned above the lower cutter roller 600. In practice, the lower cutter roller 600 and the mounting rail 100 may be mounted on a frame 800 by screwing, snapping, or other means.

[0059] In practice, the cutter 500 can be passively rotated when it comes into contact with the continuously forward-feeding copper foil to achieve the purpose of cutting the copper foil. Of course, the cutter 500 can also be actively rotated by a motor to achieve the purpose of cutting the copper foil.

[0060] like Figure 4 As shown, the separation angle refers to the angle α between the tool 500 and its deflection around the vertical axis of rotation. Figure 2 As shown, the tool gap refers to the distance δ between the cutting tool 500 and the lower cutting roller 600. For example... Figure 5 As shown, the elevation angle refers to the angle β between the tool 500 and the horizontal axis of rotation when the tool 500 deflects.

[0061] When slitting copper foil, if the cutter 500 experiences slight offset or deflection due to prolonged use or dimensional deviations during assembly, the movement of the mounting base 200, the first connecting seat 300, and / or the second connecting seat 400 can be controlled to perform three-dimensional coordinated adjustment of the cutter 500's separation angle, elevation angle, and / or blade gap. This facilitates adjusting the cutter 500 to an optimal working position, maintaining better slitting accuracy for the copper foil, and adapting to copper foil slitting operations with higher precision requirements. When the cutter 500 is adjusted to its optimal working position, the gap matching between the cutter 500 and the copper foil can be optimized, significantly reducing copper powder generation and the possibility of edge burrs on the copper foil, thus improving the quality of copper foil slitting. This solves the problem in related technologies where slitting equipment struggles to maintain optimal slitting accuracy and easily leads to high copper powder generation.

[0062] When the cutter 500 is adjusted to a better working position, the stress distribution on the contact surface between the cutter 500 and the copper foil can be more uniform, reducing local stress concentration during slitting, making the copper foil more uniformly stressed, and optimizing the slitting effect.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the mounting track 100 extends horizontally, and the mounting base 200 is slidably disposed on the mounting track 100 in the horizontal direction. The mounting base 200 can also rotate relative to the mounting track 100 about a vertical axis of rotation.

[0064] The first connecting seat 300 is slidably mounted on the mounting base 200 in a vertical direction;

[0065] The second connecting seat 400 is rotatably mounted on the first connecting seat 300 about a horizontal axis of rotation, and the axis of rotation of the second connecting seat 400 is perpendicular to the axis of rotation of the tool 500.

[0066] Therefore, the mounting base 200 can rotate relative to the mounting track 100 around the vertical rotation axis, thereby causing the tool 500 to deflect around the vertical rotation axis, thus achieving the purpose of adjusting the separation angle of the tool 500.

[0067] Furthermore, the mounting base 200 can slide relative to the mounting track 100 to adjust the relative position of the mounting base 200 on the mounting track 100. This facilitates adaptive adjustment of the copper foil cutting width during copper foil slitting.

[0068] The first connecting seat 300 can slide relative to the mounting base 200 in the vertical direction, which is equivalent to raising and lowering the first connecting seat 300, thereby driving the tool 500 to rise and fall, and thus achieving the purpose of adjusting the tool gap of the tool 500.

[0069] The second connecting seat 400 can rotate relative to the first connecting seat 300 around a horizontal rotation axis, thereby driving the tool 500 to deflect around a horizontal rotation axis and achieving the purpose of adjusting the elevation angle of the tool 500.

[0070] In other embodiments, the first connecting seat 300 may also be rotatably mounted on the mounting base 200, and the rotatable connection portion of the first connecting seat 300 may be eccentrically positioned so that when the first connecting seat 300 rotates relative to the mounting base 200, the height of the tool 500 can be adjusted, i.e., the tool gap can be adjusted. Alternatively, the first connecting seat 300 may be movably mounted on the mounting base 200 via a combination of sliding and rotation. The second connecting seat 400 may also be movably mounted on the first connecting seat 300 via a combination of sliding and rotation to adjust the elevation angle of the tool 500.

[0071] like Figure 1 and Figure 3As shown, in some embodiments, at least two mounting rails 100 are provided and are parallel to each other. The mounting base 200 includes a support beam 210 and at least two sliders 220. The support beam 210 is connected to each slider 220. The sliders 220 are correspondingly sleeved on the mounting rails 100 so that the sliders 220 are slidably connected to the mounting rails 100. There is a gap between the side of the mounting rail 100 and the side of the slider 220 so that the slider 220 can rotate relative to the mounting rails 100 about a vertical axis of rotation.

[0072] The first connecting seat 300 is slidably mounted on the support beam 210 in the vertical direction.

[0073] In this embodiment, two mounting rails 100 are provided, which are parallel to each other and spaced apart. The mounting base 200 includes a support beam 210 and two sliders 220. The two sliders 220 can be fixed to both ends of the support beam 210 in the extending direction by integral molding, screwing, welding or other means. Of course, the mounting rails 100 can also be one, three or other numbers, and the number of sliders 220 can be set according to the number of mounting rails 100.

[0074] The slider 220 has a horizontally extending through hole so that it can be fitted onto the mounting track 100. Furthermore, the width of the through hole on the slider 220 can be slightly larger than the width of the mounting track 100, so that after the slider 220 is fitted onto the mounting track 100, there is a certain gap between the side of the mounting track 100 and the sidewall of the through hole in the slider 220.

[0075] Therefore, within the allowable range of this gap, the slider 220 and the mounting base 200 as a whole can deflect relative to the mounting track 100 around the vertical axis of rotation, thereby adjusting the separation angle of the cutter 500. Furthermore, the slider 220 can also slide along the mounting track 100 to adjust the relative position of the mounting base 200 on the mounting track 100, thus facilitating rapid adjustment of the cutter 500's arrangement position. This allows for adjustment of the copper foil slitting width according to actual needs, improving slitting accuracy and adaptability, while also providing a rapid adjustment function for copper foil cutting edge trimming.

[0076] It should be noted that the size of the gap between the side of the mounting rail 100 and the side wall of the through hole in the slider 220 can be set according to actual needs and is not limited.

[0077] In other embodiments, a transmission block can be slidably disposed on the mounting track 100, and then the mounting base 200 can be rotatably disposed on the transmission block, so that the mounting base 200 can both slide and rotate relative to the mounting track 100. In other embodiments, the mounting base 200 can also be mounted on a robotic arm, so that the position of the mounting base 200 can be adjusted by the robotic arm.

[0078] like Figure 2 and Figure 3 As shown, in some embodiments, a rack portion 110 is provided on the mounting rail 100, and the extending direction of the rack portion 110 is consistent with the extending direction of the mounting rail 100.

[0079] The slider 220 is provided with a first driving member 221 and a gear 222. The gear 222 meshes with the rack portion 110. The first driving member 221 is used to control the rotation or stop the rotation of the gear 222.

[0080] It should be noted that both mounting rails 100 are provided with racks 110, and both sliders 220 are provided with first drive components 221 and gears 222.

[0081] Specifically, a groove 120 can be formed on the side surface of the mounting rail 100, and the extending direction of the groove 120 is consistent with the extending direction of the mounting rail 100. In this embodiment, the groove 120 is formed on the side surface of the mounting rail 100 away from the support beam 210. At this time, the rack portion 110 can be provided on the inner surface of the groove 120, such as the top surface, side surface, or bottom surface. In this embodiment, the rack portion 110 is provided on the top surface of the groove 120. The rack portion 110 can be connected to the mounting rail 100 by integral molding, welding, or other means.

[0082] The first driving component 221 is a motor, and the model is not limited, but a servo motor is preferred to provide a self-locking function. The first driving component 221 can be mounted on the slider 220 by screwing, snapping, or other means. The gear 222 meshes with the rack portion 110, and the gear 222 can be connected to the output shaft of the first driving component 221 by sleeve, screwing, or other means, so that the first driving component 221 can drive the gear 222 to rotate.

[0083] Thus, the two first driving components 221 can be operated synchronously to drive the gear 222 to rotate, thereby simultaneously driving the two sliders 220 to slide along the corresponding mounting track 100 to adjust the relative position of the mounting base 200 as a whole on the mounting track 100.

[0084] In addition, by operating one of the first driving components 221 individually, stopping both first driving components 221 one after the other, or making the two first driving components 221 run in opposite directions, the two sliders 220 can be misaligned, thereby causing the mounting base 200 to slightly deflect around the vertical axis of rotation, thus adjusting the separation angle of the cutter 500, so that the force is more uniform during copper foil cutting and the cutting accuracy is improved.

[0085] In implementation, the first driving member 221 can be positioned on the side of the slider 220 facing away from the support beam 210 to reduce the possibility of interference between the first driving member 221 and the tool 500. Secondly, the output shaft of the first driving member 221 can pass through the slider 220 into the through hole, and then the gear 222 can be connected to the output shaft of the first driving member 221 from inside the slider 220. Alternatively, both the first driving member 221 and the gear 222 can be positioned inside the slider 220.

[0086] In other embodiments, the first drive member 221 and gear 222 can be replaced with a quick-tension handle that passes through and is threadedly connected to the slider 220. This allows the slider 220 to be adjusted on the mounting track 100 by rotating the quick-tension handle to engage or disengage from the mounting track 100.

[0087] like Figure 2 and Figure 3 As shown, in some embodiments, a lead screw 310 is rotatably mounted on the mounting base 200, the lead screw 310 is threadedly connected to the first connecting seat 300, and the extension direction of the lead screw 310 is consistent with the sliding direction of the first connecting seat 300.

[0088] A second drive unit 320 is provided on the mounting base 200, which is used to control the rotation or stop the rotation of the lead screw 310.

[0089] Specifically, for the first connecting seat 300 to slide vertically on the support beam 210, a vertically extending guide block 230 can be integrally formed, welded, or otherwise provided on the support beam 210, with the guide block 230 located below the support beam 210. A connecting groove adapted to the guide block 230 is then formed on the first connecting seat 300. Subsequently, the first connecting seat 300 can slide on the guide block 230 through the connecting groove, so that the guide block 230 provides better support and guidance for the first connecting seat 300, improving the stability of the first connecting seat 300 when sliding vertically (i.e., lifting). The cross-section of the guide block 230 can be trapezoidal, rectangular, or other shapes.

[0090] The lead screw 310 extends vertically, and its upper part passes through and is rotatably connected to the support beam 210 about a vertical axis of rotation. A positioning part, such as a protruding ring or annular groove, can be provided on the upper part of the lead screw 310 to mate with the support beam 210. This positioning part restricts the axial freedom of the lead screw 310 during rotation, ensuring its stability relative to the support beam 210.

[0091] The lower part of the lead screw 310 is threaded through and connected to the first connecting seat 300, so that when the lead screw 310 rotates, it can drive the first connecting seat 300 to slide.

[0092] Therefore, by rotating the lead screw 310 forward or backward, the first connecting seat 300 can be raised or lowered, thereby achieving the purpose of adjusting the tool gap of the tool 500.

[0093] Meanwhile, a second drive unit 320 can be installed on the mounting base 200 via screw connection, snap-fit ​​connection, or other means. The second drive unit 320 can be a hollow geared motor or other types of motor, and there are no restrictions on this. The output shaft of the second drive unit 320 can be connected to the lead screw 310 via sleeve connection, screw connection, or other means, so as to control the rotation and stop of the lead screw 310 through the second drive unit 320, thereby improving the convenience of controlling the rotation of the lead screw 310.

[0094] In practice, a handle, such as a spool handle 330, can be installed at the top of the lead screw 310 by screwing, sleeve connection, or other means. This allows the lead screw 310 to be rotated manually in certain scenarios (such as when the second drive component 320 is damaged), improving adaptability.

[0095] In other embodiments, the first connecting seat 300 can be raised or lowered by a cylinder or a hydraulic cylinder.

[0096] like Figure 6 As shown, the material cutting device may further include a pressure detection element 700, which is used to detect the pressure on the cutter 500. The pressure detection element 700 is electrically connected to the second drive element 320, which is used to control the screw 310 to rotate or stop rotating according to the pressure, so as to dynamically adjust the blade gap and keep the pressure within a preset range.

[0097] The pressure detection element 700 can be a pressure sensor, and its model is not limited. The pressure detection element 700 can be installed between the tool 500 and the second connecting seat 400, or on the tool 500, or on the second connecting seat 400 by bonding, embedding, or other methods. The only requirement is that the pressure detection element 700 can detect the pressure on the tool 500 in real time during operation; its specific installation location is not limited.

[0098] The second drive unit 320 is electrically connected to the pressure detection unit 700, so that the second drive unit 320 can control the lead screw 310 to rotate or stop rotating according to the pressure on the cutter 500 detected by the pressure detection unit 700, thereby controlling the lifting and lowering of the first connecting seat 300 to dynamically adjust the blade gap, control the cutting depth in real time, and ensure that the pressure on the cutter 500 is within a preset range, thus ensuring a better cutting state.

[0099] like Figure 3 As shown, in some embodiments, a third driving member is also included. The second connecting seat 400 is rotatably connected to the first connecting seat 300 via the elevation angle rotating shaft 410. The third driving member is used to drive the elevation angle rotating shaft 410 to rotate or stop rotating.

[0100] The elevation angle shaft 410 extends horizontally, and its extension direction is perpendicular to the rotation axis of the tool 500. The elevation angle shaft 410 can be fixed to one of the second connecting seat 400 and the first connecting seat 300 by welding, integral molding, or other methods, and then rotatably connected to the other by plugging in. At this time, the third driving component can be screwed, snap-fitted, or otherwise mounted on the component not fixed to the elevation angle shaft 410. The third driving component can be a motor, and the model is not limited, but a servo motor and a geared motor are preferred to provide a self-locking function. The output shaft of the third driving component can be connected to the elevation angle shaft 410 by screwing, plugging in, or other methods.

[0101] Therefore, the third driving component can drive the elevation angle shaft 410 to rotate or stop rotating, thereby causing the second connecting seat 400 to deflect relative to the first connecting seat 300 around the horizontal rotation axis, so as to achieve the purpose of adjusting the elevation angle of the tool 500.

[0102] In other embodiments, a telescopic member may be provided between the second connecting seat 400 and the first connecting seat 300. The two ends of the telescopic member are connected to the second connecting seat 400 and the first connecting seat 300 respectively, so that by controlling the extension and retraction of the telescopic member, the second connecting seat 400 can be deflected relative to the first connecting seat 300. The telescopic member can be a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0103] like Figure 6 As shown, in some embodiments, a spindle 510 is slidably disposed on the second connecting seat 400, a tool 500 is rotatably disposed on the spindle 510, and a fine-tuning component 520 is disposed on the second connecting seat 400. The fine-tuning component 520 is used to control the spindle 510 to slide or stop sliding relative to the second connecting seat 400.

[0104] Specifically, the spindle 510 and the cutter 500 are coaxially arranged. The cutter 500 is sleeved and rotatably connected to the spindle 510, and the spindle 510 is slidably mounted on the second connecting seat 400 along its own axis. At this time, the second connecting seat 400 is provided with a fine-tuning component 520, which controls the sliding of the spindle 510 relative to the second connecting seat 400, which is equivalent to controlling the cutter 500 to slide slightly along its own axis, so as to further fine-tune the position of the cutter 500, and further facilitate the adjustment of the cutter 500 to a better working position to ensure better cutting accuracy.

[0105] Based on this, during implementation, the pressure detection element 700 can be installed on the spindle 510 to reflect the pressure on the tool 500 by detecting the pressure on the spindle 510, and then dynamically adjust the tool gap through the second drive element 320.

[0106] In this embodiment, the fine-tuning component 520 includes a fine-tuning nut 521, which is sleeved and threadedly connected to the main shaft 510, and is rotatably connected to the second connecting seat 400.

[0107] Specifically, a positioning ring 420 can be detachably connected to the second connecting seat 400 by screwing or other means. In this case, the fine-tuning component 520 also includes a retaining ring 522, which can be coaxially connected to the fine-tuning nut 521 by welding, screwing, or other means. The fine-tuning nut 521 is sleeved and threadedly connected to the main shaft 510, and is located on the side of the positioning ring 420 opposite to the second connecting seat 400, while the retaining ring 522 is clamped between the positioning ring 420 and the second connecting seat 400. This allows the fine-tuning nut 521 to be rotatably connected to the second connecting seat 400 via the retaining ring 522; that is, when the fine-tuning nut 521 rotates, the positioning ring 420 can restrict the axial displacement of the fine-tuning nut 521.

[0108] Therefore, by rotating the fine-tuning nut 521, the spindle 510 can be driven to slide along its own axis, thereby driving the tool 500 to slide along its own axis, thus achieving the purpose of axial fine-tuning of the tool 500.

[0109] Additionally, during installation, the fine-tuning nut 521 and retaining ring 522 can be installed on both sides of the positioning ring 420 first, and then the fine-tuning nut 521 can be connected to the retaining ring 522. Furthermore, to improve the stability of the spindle 510 sliding relative to the second connecting seat 400, at least a portion of the spindle 510 can be configured as a prism or irregular shape to restrict the circumferential rotation of the spindle 510, but axial sliding of the spindle 510 is permitted.

[0110] In other embodiments, the fine-tuning component 520 can also be configured as a fine-tuning screw, which passes through and is threadedly connected to the second connecting seat 400. The fine-tuning screw is connected to the main shaft 510, and the two extend in the same direction.

[0111] like Figure 6 As shown, in some embodiments, the tool 500 can be rotatably mounted on the spindle 510 via at least two bearings 530, the at least two bearings 530 being tapered roller bearings and arranged symmetrically.

[0112] Specifically, the cutting tool 500 can be configured as a ring structure, with an additional boss-shaped bearing sleeve 540 and a clamping ring 550. The bearing sleeve 540 has a limiting base plate 541. During installation, the cutting tool 500 and the clamping ring 550 can be coaxially sleeved on the bearing sleeve 540, with the cutting tool 500 clamped between the clamping ring 550 and the limiting base plate 541. The clamping ring 550 is then fastened to the bearing sleeve 540 by threaded connection or screw fastening. Thus, the bearing sleeve 540, the cutting tool 500, and the clamping ring 550 are installed as a single structure. This single structure can then be rotatably mounted on the spindle 510 via at least two bearings 530.

[0113] In this embodiment, two bearings 530 are provided, both of which are tapered roller bearings. Specifically, as shown... Figure 6 As shown, both bearings 530 are coaxially mounted on the main shaft 510. The two bearings 530 are adjacent and symmetrically arranged, for example, back to back (i.e., the large ends of the roller conical distribution trajectory are arranged facing each other). The bearing sleeve 540 is simultaneously mounted on both bearings 530.

[0114] Therefore, the tool 500 is rotatably mounted on the spindle 510 via two tapered roller bearings, which can effectively reduce the runout of the tool 500 and control the runout to less than 0.005mm.

[0115] During implementation, the end face of the cutting tool 500 can be machined with high precision to ensure that the thickness dimensional accuracy tolerance of the cutting tool 500 is controlled within ±0.007mm. A PLC system can also be used to collect slitting parameters, cutting tool 500 speed, etc., to record production process parameters. Simultaneously, by detecting different cutting tool 500 slitting speeds and the corresponding copper powder generation, the relationship between the cutting tool 500 slitting speed and the copper powder production can be analyzed and compared.

[0116] The manufacturing of cutting tool 500 can employ tempering, quenching, and vacuum nitriding processes to ensure its stability. For example, cutting tool 500 can be manufactured using a forging process with high-vanadium metal alloy materials, followed by heat treatment tempering, precision machining, vacuum nitriding and quenching to HRC≥65, deep cryogenic grinding and polishing, and a 2μm titanium plating to enhance wear resistance. This allows for copper foil slitting speeds of 200~800m / min, or even 800m / min and above.

[0117] For example, verification tests can be conducted on various copper foil materials (taking copper foils with thicknesses of 105μm, 145μm, 210μm, and 245μm as examples) according to different parameters (such as separation angle, elevation angle, and cutting speed), resulting in a verification test table (testing copper powder amount, tool wear at 500°, and edge burrs), as shown in Table 1. The values ​​for the separation angle α and elevation angle β can be taken as α = 1.2°~1.4° and β = 1.5°~1.8°. The formula for the copper powder generation amount (Q, unit mg / 1000m³) is: Q = 0.15α² + 0.09β² - 0.4αβ + 0.7α + 0.5β.

[0118] Finally, based on the verification test results, the optimal values ​​of the corresponding parameters (such as separation angle, elevation angle, blade gap, and cutting speed) for different copper foil materials when the copper powder suppression rate meets the requirements can be determined, as shown in Table 2.

[0119] In summary, the material slitting apparatus provided in this application, when slitting copper foil, if the cutter 500 experiences slight displacement or deflection due to prolonged use or dimensional deviations in assembly, can control the movement of the mounting base 200, the first connecting seat 300, and / or the second connecting seat 400 to perform three-dimensional coordinated adjustment of the cutter 500's separation angle, elevation angle, and / or blade gap. This facilitates adjusting the cutter 500 to an optimal working position to maintain better slitting accuracy for the copper foil, while also adapting to copper foil slitting operations with higher precision requirements. When the cutter 500 is adjusted to an optimal working position, the gap matching between the cutter 500 and the copper foil can be optimized, thereby significantly reducing the amount of copper powder generated and the possibility of edge burrs on the copper foil, improving the quality of copper foil slitting. This solves the problem in related technologies where slitting equipment struggles to maintain optimal slitting accuracy and easily leads to high copper powder generation.
