[0002] This application claims priority to Chinese patent application number 202322662014.7, filed on September 28, 2023, entitled “Cutter assembly, glue cutting device and battery production line,” the entire text of which is hereby incorporated by reference. Technical Field

[0003] The present application relates to the technical field of battery production, and in particular to a cutter assembly, a glue cutting device and a battery production line. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0005] Battery production involves numerous steps involving taping, such as taping the battery cell after ultrasonically welding the tabs, applying protective tape to the tabs, and applying tape to the end of wound cells. After taping, a cutting mechanism is required to cut the tape. The cutter in the cutting mechanism can become blunt after cutting the tape, causing the cutter to break and trigger a vacuum alarm. Therefore, the cutter must be regularly disassembled and cleaned.

[0006] However, in some cases, the rubber cutting mechanism needs to be manually disassembled and cleaned every shift, which takes up manpower and causes a high number of fault alarms, resulting in more manual intervention, a low degree of automation, and low production efficiency.

[0007] Summary of the Invention

[0008] In view of the above problems, the present application provides a cutter assembly, a glue cutting device and a battery production line, which can solve the problem that in some cases the glue cutting mechanism needs to be manually disassembled and cleaned the cutter every shift, which takes up manpower, and the number of fault alarms is large, resulting in more manual intervention, low degree of automation and low production efficiency.

[0009] In a first aspect, the present application provides a cutter assembly, comprising:

[0010] a knife holder having a cutting end, the cutting end being provided with a cutting position for releasably fixing a knife blade;

[0011] A knife box is mounted on the knife holder, and is provided with a knife storage cavity for storing a plurality of blades; and

[0012] The tool change drive is connected to the tool magazine drive and is used to drive the tool magazine to move back and forth relative to the tool holder; the tool magazine is configured to be able to unload the blade from the cutting position by moving and output the blade in the tool storage cavity to the cutting position.

[0013] In the technical solution of the embodiment of the present application, a knife magazine is installed on the knife holder so that multiple blades can be stored in the knife magazine. When cutting, the knife magazine moves with the knife holder, which has a compact structure and saves space. It can be suitable for application scenarios with smaller cutting space. By setting a knife changing drive connected to the knife magazine drive, the knife changing drive can drive the knife magazine to move relative to the knife holder to realize automatic disassembly and knife changing. There is no need for manual disassembly and knife changing, and the degree of automation is high. The replaced blades can be cleaned uniformly after collection, and there is no need to disassemble and clean them every shift. The manual operation cycle can be extended from once per shift to once a week, which greatly reduces the number of manual interventions and improves production efficiency. It effectively solves the problem that in some cases, the rubber cutting mechanism needs to be manually disassembled and cleaned every shift, which takes up manpower and has a large number of fault alarms, resulting in more manual intervention, low degree of automation, and low production efficiency.

[0014] In some embodiments, the cutter station is located on a first side of the tool holder, and a knife magazine is slidably connected to the first side of the tool holder. Sliding the knife magazine along the tool holder toward the cutting end can push the blade of the cutter station away from the cutter station. With this arrangement, the knife magazine and the cutter station are located on the same side of the tool holder, and the knife magazine can be driven along the tool holder to automatically unload the blade from the cutter station. This configuration provides a simple and reliable structure, takes up little space, is more compact, and has greater applicability.

[0015] In some embodiments, the bottom side of the knife magazine is provided with a first opening extending through the knife storage chamber. The bottom side of the knife magazine is disposed opposite the first side of the knife holder, such that the blade in the knife storage chamber is supported on the first side surface of the knife holder through the first opening. The knife magazine can slide along the knife holder until the first opening is disposed opposite the cutting position or the first opening is offset from the cutting position. This arrangement allows the knife magazine to slide along the knife holder toward the cutting end to simultaneously unload the blade from the cutting position and transfer the blade in the knife storage chamber to the cutting position. A single action can complete the replacement of the blade in the cutting position, facilitate the automatic knife changing operation of the knife magazine by the knife change drive, and improve the degree of automation, simplify and facilitate use, and save manpower.

[0016] In some embodiments, the knife magazine has a top side disposed opposite the bottom side, and the top side of the knife magazine has a second opening extending through the knife storage chamber. The cutter assembly further includes a knife pressing member pivotally disposed at the second opening of the knife magazine for pressing the blade in the knife storage chamber against the first side of the knife holder. This arrangement facilitates the insertion of the blade into the knife storage chamber, provides a simple and easy-to-operate structure, and allows the blade at the bottom of the knife storage chamber to closely contact the first side surface of the knife holder, thereby facilitating the blade at the bottom of the knife storage chamber to better support the movement of the blade at the cutting position, effectively achieving blade unloading at the cutting position and ensuring stable and reliable automatic knife changing.

[0017] In some embodiments, a stopper is further provided on the first side of the blade holder. The stopper is located adjacent to the cutting position on a side of the blade away from the cutting end. The stopper is configured to abut against the back of the blade to hold the blade in the cutting position. This allows the blade to be stably secured in the cutting position, effectively enabling blade changes, and allows the blade to better withstand cutting forces, resulting in better cutting results.

[0018] In some embodiments, the cutter assembly further comprises a backstop, which is retractably disposed on the knife magazine and located between the knife storage cavity and the front end of the knife magazine. The backstop's retraction direction intersects with the bottom surface of the knife magazine, allowing the backstop to extend or retract toward the bottom side of the knife magazine. The side of the backstop facing away from the knife storage cavity is used to block the blade. The side of the backstop near the knife storage cavity is provided with a driving bevel, which is pressed against and squeezed by the blade, thereby driving the backstop to retract toward the bottom side of the knife magazine. This further restricts the blade in the cutting position, making the blade more stable and reliable, and achieving better cutting results. In addition, the backstop can push the blade out of the cutting position, effectively achieving a stable and reliable knife change.

[0019] In some embodiments, the blade holder has a second side disposed opposite the first side, the blade holder defines a mounting opening extending through the first and second sides, and the knife magazine is capable of sliding to a position where the first opening faces the mounting opening, thereby connecting the mounting opening to the knife storage chamber. The cutter assembly further includes a cover plate movably mounted to the second side of the blade holder for opening and closing the mounting opening. This allows the blade to be loaded into the knife storage chamber from the second side of the blade holder, facilitating blade installation in spaces where installation from the first side of the blade holder is difficult, resulting in greater convenience, flexibility, and a wider range of applications.

[0020] In some embodiments, a cover plate is slidably connected to the mounting opening, capable of translating and sliding in a direction parallel to the plane of the mounting opening to open or at least partially cover the mounting opening. A second spring is connected between the cover plate and the tool holder, generating an elastic force toward the cover plate to at least partially cover the mounting opening. This arrangement allows the cover plate to at least partially cover the mounting opening when not in use.

[0021] In some embodiments, a first side of the tool holder defines a slot extending through to the cutting end. The cutting blade is positioned on the bottom inner wall of the slot at the cutting end, and a knife magazine slides within the slot. The slot serves as a guide and limiter for the sliding movement of the knife magazine relative to the tool holder, making the movement of the knife magazine relative to the tool holder more stable and controllable, effectively enabling automatic knife changing. Furthermore, the knife magazine is embedded within the tool holder, resulting in a more compact structure, further saving space, facilitating ease of use, and extending its applicability.

[0022] In some embodiments, the cutter assembly further includes a magnetic element disposed at the cutter position for magnetically securing the blade. This magnetic attraction allows the cutter position to releasably secure the blade, resulting in a simple structure, ease of use, and effective automatic blade changing.

[0023] In some embodiments, the cutter assembly further comprises a pressure plate mechanism, which is disposed at the front end of the knife magazine or the end surface of the cutting end of the knife holder. The pressure plate mechanism is configured to be capable of telescopic movement along the cutting direction of the cutter assembly, and the pressure plate mechanism is used to press the cutting object. With this arrangement, when using the cutter assembly for cutting, the pressure plate mechanism can be used to first press the cutting object to prevent the cutting object from moving during the cutting process, thereby improving the cutting effect.

[0024] In the second aspect, the present application provides a rubber cutting device, comprising: a fixed part; a movable part, mounted on the fixed part; a rubber cutting drive part, drivingly connected to the movable part, the rubber cutting drive part being used to drive the movable part to move linearly relative to the fixed part; and a cutter assembly as in any of the above embodiments, the cutter assembly being mounted on the movable part through a knife holder.

[0025] In some embodiments, the movable member includes a base plate and a connecting frame, wherein the base plate is slidably connected to the fixed member, and the connecting frame is fixedly connected to the base plate; the connecting frame is provided with at least two mounting portions spaced apart along a first direction, and / or the connecting frame is provided with at least two mounting portions spaced apart along a second direction; wherein the mounting portions are used to securely mount the cutter assembly, and the first and second directions are perpendicular to the linear movement direction of the movable member. This arrangement makes it easy to add or remove cutter assemblies, and the rubber cutting device can have a single cutter assembly or a combination of multiple cutter assemblies. The arrangement of the multiple cutter assemblies can be selected according to the needs of use, thereby realizing a modular cutter structure that is more convenient and flexible to use, meets actual use needs, and has a wider range of applications.

[0026] In some embodiments, the rubber cutting device further includes a blade receiving box, into which the blades fall after being ejected. This arrangement facilitates the collection of replaced blades for unified cleaning.

[0027] In a third aspect, the present application provides a battery production line, comprising a cutter assembly as in any of the above embodiments, or a glue cutting device as in any of the above embodiments, wherein the cutter assembly and the glue cutting device are used for cutting the tape.

[0055] Currently, market developments indicate that power batteries are becoming increasingly widely used. Power batteries are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing, and battery production is progressing towards greater efficiency.

[0056] The battery production process involves applying and cutting tape, such as applying tape to the battery cell after ultrasonically welding the tabs, applying protective tape to the tabs, and applying tape to the end of the wound battery cell. Taking an ultrasonic welding machine as an example, after the tabs are welded, the adhesive is applied. First, the adhesive puller clamps the blue adhesive and pulls it out. Then, the adhesive support plate holds the blue adhesive, and the adhesive suction plate presses down to absorb the blue adhesive. The cutter cuts the blue adhesive horizontally or vertically. The cutter mechanism is used to cut the blue adhesive applied to the battery cell. However, the blue adhesive is easily sticky when the cutter is cutting. This sticky condition can cause the cutter to become blunt and unable to cut the blue adhesive, triggering a vacuum alarm. For this reason, in some cases, the ultrasonic welding machine's adhesive cutting mechanism requires manual disassembly and cleaning of the cutter during each shift, which consumes manpower and results in frequent fault alarms, resulting in high manual intervention, low automation, and low production efficiency.

[0057] To address the issue of the aforementioned rubber cutting mechanism requiring manual removal and cleaning of the cutter blades during each shift, a cutter mechanism with an automatic blade changing function can be employed instead of the previously mentioned mechanism. Specifically, the cutter mechanism with an automatic blade changing function can include a knife magazine and a knife changing drive connected to the knife magazine. The knife magazine can store multiple blades. When a knife becomes blunt, the knife changing drive drives the knife magazine to automatically remove and replace the blade, thus achieving an automatic knife changing function. This eliminates the need for manual removal and replacement, resulting in a high degree of automation. The replaced blades are collected and cleaned collectively, eliminating the need for knife removal and cleaning during each shift. This reduces the need for manual intervention and improves production efficiency.

[0058] Based on the above considerations, in order to solve the problems of manual disassembly and cleaning of the cutter in the rubber cutting mechanism during each shift, which occupies manpower and has a high number of fault alarms, resulting in frequent manual intervention, low degree of automation and low production efficiency, a cutter assembly was designed. By arranging a knife magazine and a knife-changing drive on the knife holder, the knife magazine can store multiple blades, and the knife-changing drive can drive the knife magazine to automatically disassemble and change knives, without the need for manual disassembly and changing of knives. The degree of automation is high, and the replaced blades are collected and cleaned uniformly, without the need for disassembly and cleaning during each shift. The manual operation cycle can be extended from once per shift to once a week, greatly reducing the number of manual interventions and improving production efficiency.

[0059] The cutter assembly disclosed in the embodiments of the present application can be used, but not limited to, for cutting rubber in a battery production line, and can also be used in cutting equipment for other materials. The cutter assembly disclosed in the embodiments of the present application can be used, but not limited to, for cutting rubber in a battery production line, and can also be used for cutting other materials, such as thin plates, strips, cables, etc.

[0060] The battery production line provided in the embodiment of the present application can be used to produce new energy batteries.

[0061] The preferred embodiments of the present application are described below with reference to the accompanying drawings.

[0062] According to some embodiments of the present application, referring to Figures 1 to 3, Figure 1 shows a schematic perspective view of a cutter assembly in some embodiments of the present application, Figure 2 shows a right side view of the cutter assembly in some embodiments of the present application, and Figure 3 shows a front view of the cutter assembly in some embodiments of the present application. The present application provides a cutter assembly 10. The cutter assembly 10 includes a tool holder 1, a tool magazine 2, and a tool change drive 3. The tool holder 1 has a cutting end 11, which is provided with a cutting position 12 for releasably securing a blade 20. The tool magazine 2 is mounted on the tool holder 1 and has a tool storage chamber 21 for storing a plurality of blades 20. The tool change drive 3 is drivably connected to the tool magazine 2 and is configured to drive the tool magazine 2 to reciprocate relative to the tool holder 1. The tool magazine 2 is configured to unload the blades 20 from the cutting position 12 by moving, and to transfer the blades 20 from the tool storage chamber 21 to the cutting position 12.

[0063] As shown in FIG. 1 and FIG. 3 , the X direction in the figure is the reciprocating direction of the knife box 2 .

[0064] The tool holder 1 is a mounting frame for fixing the cutter assembly 10 to the cutting device. The cutting end 11 of the tool holder 1 is one end for mounting a fixed blade 20. The cutter assembly 10 drives the blade 20 to move through the tool holder 1 to cut the cutting object. For example, the cutting device can be a rubber cutting device, and the cutting object can be a tape or other thin or filamentous materials. The shape of the tool holder 1 can be a rectangular parallelepiped, a cylinder, a disc, etc., which is not limited here. The tool holder 1 can be a metal material, for example, the metal material can be steel, aluminum and its alloys, etc.; the tool holder 1 can also be a non-metallic material, such as hard plastic, composite material, ceramic, etc., which is not limited here.

[0065] The tool holder 1 is provided with a cutter position 12 at the cutting end 11. The cutter position 12 is a fixed structure for fixing and mounting a blade 20. The cutter position 12 releasably fixes the blade 20, meaning that the blade 20 can be fixedly mounted in the cutter position 12 so that the tool holder 1 can drive the blade 20 to move for cutting. At the same time, the blade 20 can also be disengaged from the cutter position 12 by external operation to unload the blade 20 from the cutter position 12. The fixing structure of the cutter position 12 can be a fixed surface, a fixed groove, a fixed clamp, etc., which is not limited here. The external operation can be pushing the back 201 or side of the blade 20, etc., which is not limited here.

[0066] The knife magazine 2 is installed on the knife holder 1 so that the knife magazine 2 can move with the knife holder 1; the knife storage cavity 21 is a cavity formed inside the knife magazine 2, and multiple blades 20 can be stored in the knife storage cavity 21 so that the multiple blades 20 can move with the knife magazine 2. The shape of the knife magazine 2 can be a cuboid, a cylinder, a disc, etc., which is not limited here. The knife magazine 2 can be a metal material, for example, the metal material can be steel, aluminum and its alloys, etc.; the knife magazine 2 can also be a non-metallic material, such as hard plastic, composite fabric, ceramic, etc., which is not limited here. In some embodiments, the cross-sectional shape and size of the knife storage cavity 21 are adapted to the shape and size of the blade 20, and multiple blades 20 are stacked in the knife storage cavity 21.

[0067] The tool change drive 3 is connected to the tool magazine 2 to drive the tool magazine 2 to move back and forth relative to the tool holder 1. The tool change drive 3 can be a motor, a hydraulic cylinder, an air cylinder, etc., which are not limited here. The reciprocating movement of the tool magazine 2 relative to the tool holder 1 can be linear reciprocating movement, reciprocating swinging, rotation, etc., which are not limited here. The tool magazine 2 moves relative to the tool holder 1 so that the tool magazine 2 can move closer to or away from the cutting position 12, so that the tool magazine 2 can drive the blade 20 of the cutting position 12 to disengage from the cutting position 12 to unload the blade 20 of the cutting position 12; when the tool magazine 2 moves to the cutting position 12, the tool magazine 2 can output the blade 20 in the knife storage cavity 21 to the cutting position 12, thereby replacing the blade 20 of the cutting position 12.

[0068] When the cutter assembly 10 is in use, the cutter assembly 10 is installed and fixed by the tool holder 1, a blade 20 is fixedly installed in the cutter position 12, and multiple blades 20 are stored in the knife box 2. The tool holder 1 drives the blade 20 to move to cut the cutting object; when the blade 20 at the cutter position 12 becomes blunt after use, the tool change drive 3 is started to drive the knife box 2 to move relative to the tool holder 1, and the used and blunt blade 20 on the cutter position 12 is unloaded, and one of the multiple new blades 20 stored in the knife storage chamber 21 is output to the cutter position 12, and the new blade 20 is fixedly installed in the cutter position 12, thereby realizing automatic replacement of the blade 20 at the cutter position 12.

[0069] The cutter assembly 10 of the embodiment of the present application is characterized in that a knife box 2 is installed on the knife holder 1, and the knife box 2 can store multiple blades 20. When cutting, the knife box 2 moves with the knife holder 1, which has a compact structure, saves space, and can be suitable for application scenarios with a small cutting space; by setting a knife changing drive part 3 and driving connection with the knife box 2, the knife changing drive part 3 can drive the knife box 2 to move relative to the knife holder 1 to realize automatic disassembly and change of knives, without the need for manual disassembly and change of knives, and the degree of automation is high. The replaced blades 20 can be cleaned uniformly after collection, without the need for disassembly and cleaning during each shift, and the manual operation cycle can be extended from once per shift to once per week, greatly reducing the number of manual interventions and improving production efficiency. It effectively solves the problem that in some cases, the rubber cutting mechanism needs to be manually disassembled and cleaned per shift, which takes up manpower, and the number of fault alarms is large, resulting in more manual intervention, low degree of automation, and low production efficiency.

[0070] According to some embodiments of the present application, please continue to refer to Figures 1 and 3. The cutting position 12 is arranged on the first side 13 of the tool holder 1, and the knife magazine 2 is slidably connected to the first side 13 of the tool holder 1. The knife magazine 2 slides along the tool holder 1 toward the cutting end 11 to push the blade 20 of the cutting position 12 to move away from the cutting position 12.

[0071] The first side 13 of the tool holder 1 is adjacent to the end face of the cutting end 11 of the tool holder 1. The cutting position 12 is disposed on the surface of the first side 13 of the tool holder 1 and is located at the cutting end 11 of the tool holder 1 to securely mount the blade 20 to the cutting end 11 of the tool holder 1. The knife magazine 2 is slidably connected to the first side 13 of the tool holder 1. That is, the knife magazine 2 and the cutting position 12 are disposed on the same side of the tool holder 1, so that the knife magazine 2 can slide along the first side 13 of the tool holder 1 to move closer to or away from the cutting position 12. Since the knife magazine 2 and the cutting position 12 are located on the same side of the tool holder 1, and the cutting position 12 is disposed at the cutting end 11, when the knife magazine 2 slides along the tool holder 1 toward the cutting end 11, it can push the blade 20 of the cutting position 12 to move relative to the tool holder 1 and disengage from the cutting position 12, thereby achieving unloading of the blade 20 of the cutting position 12.

[0072] By arranging the knife box 2 and the cutting position 12 on the same side of the knife holder 1, and the knife box 2 is slidably connected to the knife holder 1, the knife box 2 can be driven to slide along the knife holder 1 to realize the automatic unloading of the blade 20 on the cutting position 12. The structure is simple and reliable, occupies less space, has a more compact structure, and is more applicable.

[0073] According to some embodiments of the present application, referring to Figures 1 to 3 and further to Figure 4, Figure 4 shows a schematic diagram of the three-dimensional structure of the knife magazine in some embodiments of the present application. The bottom side 22 of the knife magazine 2 is provided with a first opening 23 that extends through the knife storage cavity 21. The bottom side 22 of the knife magazine 2 is arranged opposite the first side 13 of the knife holder 1, so that the blade 20 in the knife storage cavity 21 is supported on the surface of the first side 13 of the knife holder 1 through the first opening 23; the knife magazine 2 can slide along the knife holder 1 until the first opening 23 is opposite to the cutting position 12 or the first opening 23 is offset from the cutting position 12.

[0074] The bottom side 22 of the knife magazine 2 is disposed opposite the first side 13 of the knife holder 1, and the first opening 23 is disposed on the bottom side 22 of the knife magazine 2, i.e., the first opening 23 faces the first side 13 of the knife holder 1, so that the knife storage chamber 21 is connected to the surface of the first side 13 of the knife holder 1, thereby allowing the blade 20 in the knife storage chamber 21 to be directly supported on the surface of the first side 13 of the knife holder 1 through the first opening 23. The knife magazine 2 can slide along the knife holder 1 until the first opening 23 is disposed opposite the cutting position 12, at which point the blade 20 in the knife storage chamber 21 is supported on the cutting position 12, thereby enabling the blade 20 in the knife storage chamber 21 to be transferred to the cutting position 12. The knife magazine 2 can also slide along the knife holder 1 until the first opening 23 is offset from the cutting position 12, at which point the blade 20 in the knife storage chamber 21 is supported on the surface of the first side 13 outside the cutting position 12. In some embodiments, the shape and size of the first opening 23 are the same as the cross-sectional shape and size of the knife storage chamber 21.

[0075] When the cutter assembly 10 performs a tool changing operation, the tool changing drive 3 drives the knife box 2 to slide along the knife holder 1, and the knife box 2 drives the blade 20 in the knife storage chamber 21 to move, so that the blade 20 at the bottom of the knife storage chamber 21 in contact with the knife holder 1 moves along the first side 13 surface of the knife holder 1; in the process of the knife box 2 sliding along the knife holder 1 toward the cutting end 11, the blade 20 at the bottom of the knife storage chamber 21 moves toward the cutting position 12 along the first side 13 surface of the knife holder 1, and the blade 20 at the bottom of the knife storage chamber 21 can support and push the blade 20 on the cutting position 12 to move toward the cutting end 11, so that the blade 20 on the cutting position 12 moves and separates from the cutting position 12; when the knife box 2 slides to the first When the opening 23 is opposite to the cutting position 12, the blade 20 on the cutting position 12 is completely separated from the cutting position 12, thereby realizing the unloading of the blade 20 on the cutting position 12. At the same time, the blade 20 at the bottom of the knife storage chamber 21 falls on the cutting position 12, and the cutting position 12 fixes the blade 20 at the bottom of the knife storage chamber 21 and replaces the unloaded blade 20; the tool changing drive 3 continues to drive the knife magazine 2 to slide along the tool holder 1 away from the cutting end 11, and the knife magazine 2 drives the blade 20 in the knife storage chamber 21 to move away from the cutting position 12. Since the blade 20 at the bottom of the knife storage chamber 21 is fixed by the cutting position 12 and remains in the cutting position 12, the blade 20 at the cutting position 12 is replaced, thereby completing the automatic tool changing action.

[0076] By setting a first opening 23 on the bottom side 22 of the knife magazine 2, the knife storage chamber 21 is connected to the first side 13 surface of the knife holder 1, and the blade 20 in the knife storage chamber 21 is supported on the first side 13 surface of the knife holder 1, so that the knife magazine 2 slides along the knife holder 1 toward the cutting end 11, which can simultaneously realize the unloading of the blade 20 on the cutting position 12 and the output of the blade 20 in the knife storage chamber 21 to the cutting position 12. The blade 20 of the cutting position 12 can be replaced in one action, which is convenient for the tool changing drive 3 to drive the knife magazine 2 to perform automatic tool changing, which is conducive to improving the degree of automation, is simple and convenient to use, and saves manpower.

[0077] According to some embodiments of the present application, with continued reference to Figures 1 and 3, the knife magazine 2 has a top side 24 arranged opposite to the bottom side 22, and the top side 24 of the knife magazine 2 is provided with a second opening 25 that passes through to the knife storage cavity 21; the cutter assembly 10 also includes a knife pressing member 4, which is pivotally arranged at the second opening 25 on the knife magazine 2, and is used to press the blade 20 in the knife storage cavity 21 onto the first side 13 of the knife holder 1.

[0078] The knife magazine 2 has a bottom side 22 and a top side 24 that are arranged opposite each other, and a knife storage cavity 21 is provided within the knife magazine 2. The first opening 23 of the bottom side 22 and the second opening 25 of the top side 24 both extend through the knife storage cavity 21. In other words, the first opening 23, the knife storage cavity 21, and the second opening 25 form a through slot that passes through the top side 24 and the bottom side 22 of the knife magazine 2. The top side 24 of the knife magazine 2 is the side facing away from the knife holder 1, which facilitates the placement of the blade 20 into the knife storage cavity 21 through the second opening 25 of the top side 24. In some embodiments, the shape and size of the second opening 25 are the same as the cross-sectional shape and size of the knife storage cavity 21.

[0079] The blade pressing member 4 is pivotally disposed at the second opening 25 of the knife magazine 2. This means that the blade pressing member 4 is capable of rotating about a pivot 41, and the pivot 41 is disposed at the second opening 25 of the knife magazine 2. The blade pressing member 4 rotates relative to the knife magazine 2 about the pivot 41. The side of the blade pressing member 4 away from the pivot 41 can rotate through the second opening 25 to extend into the knife storage chamber 21, pressing against the multiple blades 20 stacked in the knife storage chamber 21 to press the multiple blades 20 against the surface of the first side 13 of the knife holder 1. Rotating the side of the blade pressing member 4 away from the pivot 41 away from the second opening 25 facilitates the insertion of blades 20 into the knife storage chamber 21 through the second opening 25.

[0080] In some embodiments, referring to Figures 1 and 3, a pivot 41 is disposed on one side of the second opening 25 and is parallel to the side edge of the second opening 25. One side of the blade pressing member 4 is connected to the pivot 41 via a torsion spring 42, and the other side of the blade pressing member 4 is pressed against the blade 20 in the blade storage chamber 21. When inserting the blade 20 into the knife magazine 2, the blade pressing member 4 is manually pulled up, the blade 20 is placed into the blade storage chamber 21, and the blade pressing member 4 is released to press the blade 20.

[0081] By providing the second opening 25 and the knife pressing member 4, it is convenient to load the blade 20 into the knife storage chamber 21. The structure is simple and easy to operate. The knife pressing member 4 can press the blade 20 against the surface of the first side 13 of the knife holder 1, so that the blade 20 at the bottom of the knife storage chamber 21 can be close to the surface of the first side 13 of the knife holder 1, which is beneficial for the blade 20 at the bottom of the knife storage chamber 21 to better support the movement of the blade 20 of the cutting position 12, effectively realize the unloading of the blade 20 at the cutting position 12, and the automatic tool changing is stable and reliable.

[0082] According to some embodiments of the present application, referring again to FIG. 1 and further to FIG. 5 , which illustrates a schematic perspective view of the blade holder in some embodiments of the present application, the blade holder 1 further includes a first side 13 provided with a stopper 14 . The stopper 14 is disposed adjacent to the cutting position 12 on a side away from the cutting end 11 . The stopper 14 is configured to abut against the back 201 of the blade 20 to retain the blade 20 in the cutting position 12 .

[0083] The stopper 14 abuts against the back 201 of the blade 20. Thus, when the knife magazine 2 slides away from the cutting position 12, the stopper 14 prevents the blade 20 that has landed in the cutting position 12 from following the knife magazine 2, ensuring that the blade 20 remains in the cutting position 12, thereby effectively achieving the knife change operation. Simultaneously, when the cutter assembly 10 performs a cutting operation, the stopper 14 abuts against the back 201 of the blade 20, better absorbing the cutting force exerted on the blade 202 and preventing the blade 20 from being subjected to excessive force and leaving the cutting position 12, thereby achieving a better cutting effect.

[0084] In some embodiments, as shown in Figure 5, a boss 15 is provided on the surface of the first side 13 of the tool holder 1, and the limiting portion 14 is the side of the boss 15 close to the cutting end 11. The surface of the first side 13 between the boss 15 and the end face of the cutting end 11 forms a cutting position 12, and the blade 20 is limited to the cutting position 12 by the side of the boss 15 abutting against the back of the blade 201 of the blade 20.

[0085] By providing the limiting portion 14 , the blade 20 can be stably fixed at the cutting position 12 , effectively realizing the blade changing action, and the blade 20 can better withstand the cutting force, resulting in a better cutting effect.

[0086] According to some embodiments of the present application, continue to refer to Figures 1, 3 and 4, and further refer to Figure 6, which shows a sectional view of the AA section in Figure 3. The cutter assembly 10 also includes a check member 5, which is retractably arranged on the knife magazine 2 and is located between the knife storage cavity 21 and the front end 26 of the knife magazine 2. The retraction direction of the check member 5 intersects with the surface of the bottom side 22 of the knife magazine 2, so that the check member 5 can extend or retract the bottom side 22 of the knife magazine 2; the side of the check member 5 facing away from the knife storage cavity 21 is used to block the blade 20, and the side of the check member 5 close to the knife storage cavity 21 is provided with a driving bevel 51, which is abutted and squeezed by the blade 20, and can drive the check member 5 to retract the bottom side 22 of the knife magazine 2.

[0087] The telescopic movement of the check member 5 means that the check member 5 can move in a translational manner along the direction of the telescopic movement. The front end 26 of the knife magazine 2 refers to the end facing the same direction as the cutting end 11 of the knife holder 1. The side of the check member 5 facing away from the knife storage chamber 21, that is, the side of the check member 5 facing the cutting end 11 of the knife holder 1. The driving inclined surface 51 is an inclined surface that is inclined toward the knife holder 1 relative to the telescopic movement direction of the check member 5. In some embodiments, the telescopic direction of the check member 5 is perpendicular to the bottom side 22 surface of the knife magazine 2.

[0088] The backstop 5 is arranged between the knife storage cavity 21 and the front end 26 of the knife magazine 2. When the knife magazine 2 slides to the first opening 23 and is misaligned with the cutting position 12, the backstop 5 can extend out of the bottom side 22 of the knife magazine 2 and abut against the cutting position 12; at this time, the blade 20 on the cutting position 12 abuts against the side of the backstop 5 away from the knife storage cavity 21, and the backstop 5 can prevent the blade 20 of the cutting position 12 from moving toward the knife storage cavity 21, thereby stably limiting the blade 20 at the cutting position 12 and preventing the blade 20 from leaving the cutting position 12; at the same time, during the process of the knife magazine 2 sliding toward the cutting end 11, the backstop 5 can abut against the movement of the blade 20 of the cutting position 12 until the blade 20 leaves the cutting position 12, effectively realizing the unloading of the blade 20 of the cutting position 12. During the process of the knife magazine 2 sliding in the direction away from the cutting end 11, since the driving bevel 51 is located on the side close to the knife storage chamber 21, the blade 20 located on the side of the check member 5 close to the knife storage chamber 21 can abut against and squeeze the driving bevel 51, driving the check member 5 to retract the bottom side 22 of the knife magazine 2. At this time, the check member 5 can avoid the blade 20 that has just fallen on the cutting position 12 until the check member 5 is away from the side of the knife storage chamber 21 and abuts against the blade 20 at the cutting position 12 again.

[0089] In some embodiments, as shown in Figures 4 and 6, the check member 5 can be a check pin, and a mounting hole is opened on the surface of the bottom side 22 of the knife magazine 2, and the check pin is movably arranged in the mounting hole; a first spring 52 is also provided in the mounting hole, and the first spring 52 is used to drive the check pin to extend out of the bottom side 22 of the knife magazine 2.

[0090] In some embodiments, as shown in FIG4 , a limiting hole 203 is provided on the blade 20 , and the return stop 5 is passed through the limiting hole 203 . The side of the return stop 5 facing away from the blade storage cavity 21 abuts against the inner wall of the limiting hole 203 .

[0091] By setting the check member 5, the blade 20 can be further limited at the cutting position 12, the blade 20 is fixed more stably and reliably, and the cutting effect is better. Moreover, the check member 5 can push the blade 20 at the cutting position 12 to unload, effectively realizing the tool changing action, and the tool changing is stable and reliable.

[0092] According to some embodiments of the present application, continue to refer to Figures 1 and 2, and further refer to Figures 7 and 8. Figure 7 shows a rear view of the cutter assembly in some embodiments of the present application, and Figure 8 shows a rear view of the cutter assembly in other embodiments of the present application. The knife holder 1 has a second side 16 arranged opposite to the first side 13. The knife holder 1 is provided with a mounting opening 17 that passes through the first side 13 and the second side 16. The knife magazine 2 can slide to a first opening 23 opposite to the mounting opening 17, so that the mounting opening 17 is connected to the knife storage chamber 21. The cutter assembly 10 also includes a cover plate 6, which is movably mounted on the second side 16 of the knife holder 1. The cover plate 6 is used to open or at least partially cover the mounting opening 17.

[0093] The second side 16 of the tool holder 1 is the side of the tool holder 1 facing away from the knife magazine 2. The mounting opening 17 is connected to the knife storage cavity 21, and the blade 20 can be placed into the knife storage cavity 21 through the mounting opening 17. In some embodiments, the size of the mounting opening 17 is larger than the size of the first opening 23, and the orthographic projection of the first opening 23 on the first side 13 of the tool holder 1 is located within the mounting opening 17. The cover plate 6 is movable to open the mounting opening 17, facilitating the placement of the blade 20 into the knife storage cavity 21 through the mounting opening 17; the cover plate 6 at least partially blocks the mounting opening 17, and the blade 20 at the bottom of the knife storage cavity 21 can be supported on the cover plate 6.

[0094] In some embodiments, as shown in FIG8 , the cover plate 6 is slidably connected to the mounting opening 17 and can slide and translate in a direction parallel to the plane of the mounting opening 17 to open or at least partially block the mounting opening 17. A second spring 61 is further connected between the cover plate 6 and the tool holder 1. The second spring 61 generates an elastic force toward the cover plate 6 to at least partially block the mounting opening 17, so that the cover plate 6 is in a state of at least partially blocking the mounting opening 17 when not being operated. In some embodiments, the sliding direction of the cover plate 6 is parallel to the sliding direction of the tool magazine 2.

[0095] By providing the mounting opening 17 and the movable cover 6, the blade 20 can be loaded into the blade storage cavity 21 from the second side 16 of the blade holder 1, which facilitates the installation of the blade 20 when space is limited and it is difficult to install the blade 20 from the first side 13 of the blade holder 1. The use is more convenient and flexible, and the scope of use is wider.

[0097] The chute 18 extends through the cutting end 11. Specifically, the end surface of the cutting end 11 has an opening that connects to the chute 18. The cutting position 12 is disposed on the bottom inner wall of the chute 18 at the opening, so that the cutting edge 202 of the blade 20 fixedly mounted to the cutting position 12 extends beyond the end surface of the cutting end 11. The chute 18 may be a straight through slot, with the knife magazine 2 slidably disposed within the chute 18, allowing the knife magazine 2 to slide linearly along the chute 18. In this embodiment, the surface of the first side 13 of the tool holder 1 serves as the bottom inner wall of the chute 18.

[0098] In some embodiments, as shown in Figures 4 and 5, guide edges 19 are further protruded on opposite sides of the slide groove 18, and the guide edges 19 extend along the extension direction of the slide groove 18; guide grooves 27 are opened on opposite sides of the knife magazine 2, and the guide grooves 27 are slidably fitted with the guide edges 19, which can guide and limit the sliding of the knife magazine 2 in the slide groove 18, and the knife magazine 2 slides more smoothly relative to the knife holder 1.

[0099] By setting the slide groove 18, the tool magazine 2 slides along the slide groove 18, and the slide groove 18 can play a guiding and limiting role in the sliding of the tool magazine 2 relative to the tool holder 1. The movement of the tool magazine 2 relative to the tool holder 1 is more stable and controllable, and automatic tool changing is effectively realized. Moreover, the tool magazine 2 is embedded in the tool holder 1, and the structure is more compact, which further saves space, is convenient to use, and has a wider range of applications.

[0100] According to some embodiments of the present application, in some embodiments, referring to FIG. 5 , the cutter assembly 10 further includes a magnetic member 7 , which is disposed at the cutter position 12 , and is used to magnetically attract the fixed blade 20 .
