Technical Field

[0001] The present application relates to the technical field of lithium battery manufacturing, and in particular to a glue sticking machine. Background Art

[0002] In lithium battery manufacturing plants, the battery module gluing machine has a problem of inconsistent width when making buffer pads.

[0003] The above is merely a description of the relevant technology and does not mean that the applicant admits that the above is the prior art.

[0004] In view of this, it is necessary to provide a new glue sticking machine to solve or at least alleviate the above technical defects. Utility Model Content

[0005] In view of the above problems, the present application provides a glue laminating machine, which aims to solve the technical problem of inconsistent width of the glue laminating machine when making buffer pads in the related art.

[0006] According to some embodiments of the present application, the present application provides a glue laminating machine, including a bracket, a cutter assembly and a guide roller, the guide roller is installed on the bracket, the cutter assembly includes a rotating rod and a cutter arranged on the rotating rod, the rotating rod is rotatably installed on the bracket, and a gap is formed between the rotating rod and the guide roller.

[0007] By rotatably mounting the rotating rod on the bracket, the cutting knife on the rotating rod is driven to cut the buffer pad during the rotating process of the rotating rod, and by setting a suitable moving speed of the buffer pad and the rotating speed of the rotating rod, the width of the buffer pad cut can be made equal. This embodiment has the advantages of basically consistent cutting width of the buffer pad and high cutting efficiency.

[0008] In some embodiments, the glue laminating machine further comprises a bottom supporting film arranged at the gap, and the bottom supporting film is rollingly connected to the guide roller.

[0009] By providing the bottom supporting film, it can not only protect the cutter, but also drive the buffer pad to move together.

[0010] In some embodiments, the glue applicator is used to cut a buffer pad, which includes a stacked rubber layer, a double-sided adhesive layer and a transition film layer, wherein the rubber layer is placed on the base film and the transition film layer is placed facing the cutter.

[0011] By providing a bottom film to support the rubber layer of the buffer pad and cutting from the transition film layer of the buffer pad, it can ensure complete cutting and reduce the risk of continuous cutting of the double-sided adhesive, and can also protect the release film.

[0012] In some embodiments, there are multiple cutters, each of which extends along the axial direction of the rotating rod, and the multiple cutters are distributed circumferentially around the periphery of the rotating rod at intervals.

[0013] By arranging multiple cutters on the rotating rod, and each cutter extends along the circumference of the rotating rod, the multiple cutters are arranged at intervals, and the multiple cutters are arranged around the outer circumference of the rotating rod, the buffer pad can be continuously cut by the rotation of the rotating rod. Compared with the cutting method of up and down movement in the related art, this embodiment does not require pause and has the advantage of high cutting efficiency.

[0014] In some embodiments, the plurality of cutters are evenly distributed around the periphery of the rotating rod.

[0015] By arranging a plurality of cutters evenly distributed around the periphery of the rotating rod, the spacing between any two adjacent cutters is equal, which further ensures that the width of the buffer pad after cutting is consistent, which is conducive to mass production.

[0016] In some embodiments, the guide roller is rotatably mounted on the bracket.

[0017] By rotatably mounting the guide roller on the bracket, the guide roller can rotate around its own central axis during actual use, thereby playing a supporting and guiding role.

[0018] In some embodiments, the rotation direction of the rotating rod is opposite to the rotation direction of the guide roller.

[0019] By rotating the rotating rod in the opposite direction to the rotating direction of the guide roller, the guide roller rotates counterclockwise while the rotating rod rotates clockwise, or the guide roller rotates clockwise while the rotating rod rotates counterclockwise, it has the advantage of facilitating cutting of the buffer pad.

[0020] In some embodiments, the glue laminating machine further includes a guide roller, wherein the guide roller, the cutter assembly, and the guide roller are sequentially spaced apart along a height direction of the bracket, and the guide roller is disposed at the top of the cutter assembly.

[0021] By setting the guide roller, the buffer pad to be cut first passes through the guide roller and then extends into the gap between the rotating rod and the guide roller. The guide roller plays a tensioning and guiding role, so that the buffer pad will not bend during the cutting process, thereby improving the cutting accuracy.

[0022] In some embodiments, the guide roller is rotatably mounted to the bracket.

[0023] By rotatably mounting the guide roller on the bracket, the guide roller can rotate around its own central axis during actual use, thereby playing a tensioning and guiding role.

[0024] In some embodiments, the cutter includes a first side and a second side arranged opposite to each other, and a bottom edge and a bevel connecting the first side and the second side respectively, the bottom edge is connected to the rotating rod, and the bevel connects the first side and the second side.

[0025] The cutter includes a first side edge, a second side edge, a bottom edge and a bevel edge which are arranged opposite to each other. The bevel edge is arranged so that a tip is formed on the side of the cutter away from the rotating rod. The tip is used to move toward the gap to cut the buffer pad, making it more convenient to cut the buffer pad.

[0026] In some embodiments, the radial length of the second side along the rotating rod is greater than that of the first side, and along the rotating direction of the rotating rod, the inclined surface extends from the first side to the second side away from the rotating rod.

[0027] By setting the radial length of the second side edge along the rotating rod to be greater than that of the first side edge, along the rotating direction of the rotating rod, the inclined surface extends from the first side edge to the second side edge away from the rotating rod, which is conducive to quickly cutting the buffer pad.

[0028] In some embodiments, a radial length of the cutter along the rotating rod is smaller than a distance between the rotating rod and the guide roller.

[0029] By limiting the maximum length of the cutter, sufficient space is left for the buffer pad and the cutter to move, making it convenient for the buffer pad and the cutter to buffer in the gap, thereby reducing the risk of jamming or chipping of the cutter due to limited space.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0050] The glue sticking machine disclosed in the embodiment of the present application is used to make a buffer pad, which is arranged between adjacent battery cells and made into a battery pack together with the battery cells and the box body. The battery pack is used as an electrical device for power supply or various energy storage systems using the battery pack as an energy storage element. The electrical device can be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Among them, the electric toy can include fixed or mobile electric toys, for example, game consoles, electric car toys, electric ship toys, electric airplane toys, and the like, and the spacecraft can include airplanes, rockets, space shuttles, spacecrafts, and the like.

[0051] Because the battery cells inside the battery pack will expand and contract due to heat and cold during use, the buffer pad has a certain degree of elasticity. The buffer pad is set between adjacent battery cells mainly to play an isolation and buffering role. In the current battery manufacturing process, the buffer pad is obtained by cutting the incoming material buffer pad with a cutter, however, there is a problem of inconsistent width. The applicant has found through research that the existing cutting method is flat knife cutting, that is, a plurality of long blades are arranged on a movable plate, and the buffer pad moves in one direction. The long cutter is moved downward by controlling the movable plate to move up and down to cut the buffer pad. For example, if there are 5 long blades on a plate, 4 rubber strips can be cut for the first time, and the width of the rubber strip is the distance between two adjacent long blades. After cutting downwards once, the moving plate is controlled to move upwards, and there will be a slight pause, and then the long blade moves downwards to continue cutting the buffer pad. The width of the fifth rubber strip cut in this way is actually determined by the cut between the last long blade cut in the previous cut and the first long blade cut this time. This width is not only affected by the moving speed of the buffer pad, but also by the cutter pause time and the cutting up and down moving speed, which makes this width difficult to control and may be inconsistent with the width of the previous 4 rubber strips. There is a problem of narrowing or widening the width of the rubber strip, resulting in a high product defect rate. In addition, due to the time pause between the two cuts and the time required for the moving plate to move up and down, the production efficiency is low.

[0052] To this end, the present application provides a glue sticking machine.

[0053] Reference Figure 1 and Figure 2 According to some embodiments of the present application, the present application provides a glue laminating machine 10, including a bracket 1, a cutter assembly 2 and a guide roller 3, the guide roller 3 is installed on the bracket 1, the cutter assembly 2 includes a rotating rod 21 and a cutter 22 arranged on the rotating rod 21, the rotating rod 21 is rotatably installed on the bracket 1, and a gap 6 is formed between the rotating rod 21 and the guide roller 3.

[0054] The bracket 1, as the main part of the glue laminating machine 10, can also be called a frame, a shell or a casing, which plays a supporting role and provides connection positions for various components. The guide roller 3 is a cylindrical roller, which is installed on the bracket 1. The outer circumference of the guide roller 3 is used for frictional contact connection with the buffer pad 20 to be cut. The guide roller 3 here can be fixedly installed on the bracket 1. The buffer pad is inserted into the gap 6 formed between the guide roller 3 and the rotating rod 21, and can move in the gap 6. The cutter assembly 2 includes a rotating rod 21 and a cutter 22 arranged on the rotating rod 21. The rotating rod 21 is used to be installed on the bracket 1, specifically, it is rotatably installed on the bracket 1, so that the rotating rod 21 can rotate around its own central axis on the bracket 1, thereby driving the cutter 22 arranged on the rotating rod 21 to rotate. During the rotation of the cutter 22, the buffer pad 20 moving in the gap 6 is cut, and the buffer pad 20 is divided into small portions of equal width. In this embodiment, the rotating rod 21 rotates continuously without setting a pause time. The rotation of the rotating rod 21 drives the cutters 22 set at different positions on the rotating rod 21 to cut the buffer pad 20. This is a continuous cutting process with high cutting efficiency. At this time, the speed of the buffer pad 20 and the speed of the rotating rod 21 can be set to move at a uniform speed, which can ensure that each small portion of the buffer pad cut off has equal width.

[0055] By rotatably mounting the rotating rod 21 on the bracket 1, the cutting knife 22 on the rotating rod 21 is driven to cut the buffer pad 20 during the rotation of the rotating rod 21, and by setting a suitable moving speed of the buffer pad 20 and the rotation speed of the rotating rod 21, the width of the cut buffer pad 20 can be made equal. This embodiment has the advantages of substantially consistent cutting width of the buffer pad 20 and high cutting efficiency.

[0056] Reference Figure 3 and Figure 4 In some embodiments, the glue laminating machine 10 further includes a bottom supporting film 5 disposed at the gap 6 , and the bottom supporting film 5 is rollingly connected to the guide roller 3 .

[0057] The bottom film 5 is a film body, which can be made of ordinary plastic material. The bottom surface of the bottom film 5 is connected to the guide roller 3 in a rolling manner, and the top surface of the bottom film 5 is used to support the buffer pad 20 and can move with the buffer pad 20. When the cutter 22 cuts, due to the excessive stroke or wear of the cutter 22 during use, the cutting depths designed for each cutter 22 are different, and some cutters 22 may hit the guide roller 3, causing the cutter 22 to wear or break teeth. In addition, the bottom film 5 can also drive the buffer pad 20 to move together.

[0058] The bottom support film 5 can not only protect the cutter 22 but also drive the buffer pad 20 to move together through friction.

[0059] Reference Figure 3 to Figure 5 In some embodiments, the glue laminating machine 10 is used to cut the buffer pad 20, which includes a stacked rubber layer 201, a double-sided adhesive layer 202 and a transition film layer 203. The rubber layer 201 is placed on the bottom film 5, and the transition film layer 203 is placed facing the cutter 22.

[0060] In the related art, there is always a phenomenon that the buffer pad 20 leaves a cut mark on the release paper or the double-sided adhesive tape cannot be cut after being cut. The applicant has found through research that the incoming buffer pad 20 includes a rubber layer 201, a double-sided adhesive layer 202 and a release paper arranged in layers, the rubber layer 201 is arranged on the top layer, and the cutter 22 cuts downward from one side of the rubber layer 201. If the stroke of the cutter 22 is not enough, the double-sided adhesive layer 202 cannot be cut, and the double-sided adhesive tape cannot be cut; and if the stroke of the cutter 22 is too high, the release paper will be cut or a cut mark will be left on the release paper. The cut of the release paper will affect the subsequent winding process, and the release paper with a cut mark is also easy to break during the subsequent winding process, affecting the subsequent production. Therefore, the stroke control requirements of the cutter 22 are very high, which is difficult to achieve in actual production, resulting in the long-term existence of the technical problem that the double-sided adhesive tape cannot be cut or there are cut marks on the release paper. In addition, when the cutter 22 cuts the release paper, vacuum alarms will frequently occur, which brings great trouble to production. In this embodiment, the rubber film is placed on the supporting film 5, the double-sided adhesive layer 202 is arranged on the rubber layer 201, and the transition film is arranged on the double-sided adhesive layer 202. When the cutter 22 is cutting, the transition film layer 203 on the uppermost side is cut first, and then the double-sided adhesive layer 202 is cut, and finally the rubber layer 201 is cut, so that the double-sided adhesive layer 202 will not be cut. In addition, by setting the supporting film 5, a little more can be set when setting the stroke of the cutter 22 to ensure that the rubber layer 201 is cut off. Even if the stroke of the cutter 22 is allowed to be slightly higher, it is cut on the supporting film 5 and will not damage the cutter 22. Therefore, the stroke setting requirements for the cutter 22 are relatively low. It should also be noted that the transition film layer 203 is made of ordinary plastic and only plays a transition role. After the cutting is completed, the transition film layer 203 will be removed, and then a whole piece of release paper will be pasted. Since the release paper is attached after the cutting process is completed, it will not be damaged by the cutting and there will be no cut marks.

[0061] By providing a bottom film 5 to support the rubber layer 201 of the buffer pad 20 and cutting from the transition film layer 203 of the buffer pad 20, it can ensure complete cutting and reduce the risk of continuous cutting of the double-sided adhesive, and can also protect the release film.

[0062] Reference Figure 3 and Figure 4 In some embodiments, there are multiple cutters 22 , each of which extends along the axial direction of the rotating rod 21 , and the multiple cutters 22 are circumferentially spaced around the periphery of the rotating rod 21 .

[0063] The axial direction of the rotating rod 21 refers to the direction of the central axis of the rotating rod 21. The cutter 22 is generally a long strip cutter. The extension of the cutter 22 along the axial direction of the rotating rod 21 means that the length direction of the cutter 22 is parallel to the central axis of the rotating rod 21. The cutter 22 is installed on the outer circumferential surface of the rotating rod 21, and multiple cutters 22 are circumferentially spaced and distributed on the outer circumferential surface of the rotating rod 21. This circumferential spacing distribution means that the cutters 22 are arranged on the outer circumferential surface of the rotating rod 21 and are circumferentially distributed around the central axis of the rotating rod 21. The length of the cutter 22 defines the length of the buffer pad 20 finally cut, and the spacing between adjacent cutters 22 defines the width of the buffer pad 20 cut. By setting multiple cutters to be spaced around the outer circumference of the rotating rod 21, except for the cutter 22 that cuts for the first time, each subsequent cutter 22 can cut a small buffer pad 20, and continuous cutting is achieved by the rotation of the rotating rod 21 without pausing in the middle, thereby improving the cutting efficiency.

[0064] By arranging multiple cutters 22 on the rotating rod 21, and each cutter 22 extends along the circumference of the rotating rod 21, the multiple cutters 22 are arranged at intervals, and the multiple cutters 22 are arranged around the outer circumference of the rotating rod 21, the buffer pad 20 can be continuously cut by the rotation of the rotating rod 21. Compared with the cutting method of moving up and down in the related art, this embodiment does not require pause and has the advantage of high cutting efficiency.

[0065] Reference Figure 3 and Figure 4 In some embodiments, the plurality of cutters 22 are evenly distributed around the periphery of the rotating rod 21 .

[0066] Here, the periphery around the rotating rod 21 refers to that multiple cutters 22 are all arranged on the outer circumferential surface of the rotating rod 21 and are distributed in a circle around the central axis of the rotating rod 21. Uniform distribution means that the distance between any two adjacent cutters 22 is equal, and the distance between any two adjacent cutters 22 determines the width of the buffer pad 20 cut off, so that the width of all the buffer pads 20 cut off can be kept consistent by simply keeping the rotating rod 21 and the buffer pad moving at a constant speed.

[0067] By arranging a plurality of cutters 22 evenly distributed around the periphery of the rotating rod 21 , the spacing between any two adjacent cutters 22 is equal, thereby ensuring that the width of the cut buffer pad 20 is consistent, which is conducive to mass production.

[0068] In some embodiments, the guide roller 3 is rotatably mounted on the bracket 1 .

[0069] The guide roller 3 here can be fixedly mounted on the bracket 1, and the buffer pad 20 is moved in the gap 6 by pulling with external force, and the guide roller 3 plays a supporting role. Of course, the guide roller 3 can also be rotatably mounted on the bracket 1, so that during the movement of the buffer pad 20, the friction between the guide roller 3 and the buffer pad 20 will drive the guide roller 3 to rotate together, and the guide roller 3 can also play a guiding role at this time. Of course, the guide roller 3 can also be connected to a power component, and the guide roller 3 is driven to rotate by the power component. The buffer pad 20 is moved together by the rotation of the guide roller 3 and the friction between the guide roller 3 and the buffer pad 20, and the guide roller 3 can also play a supporting and guiding role at this time.

[0070] By rotatably mounting the guide roller 3 on the bracket 1 , the guide roller 3 can rotate around its own central axis during actual use, thereby playing a supporting and guiding role.

[0071] Reference Figure 3 and Figure 4 In some embodiments, the rotation direction of the rotating rod 21 is opposite to the rotation direction of the guide roller 3.

[0072] The guide roller 3 and the rotating rod 21 are both cylindrical, and the rotation direction is counterclockwise or clockwise. The opposite rotation direction here means that the guide roller 3 rotates counterclockwise and the rotating rod 21 rotates clockwise, or the guide roller 3 rotates clockwise and the rotating rod 21 rotates counterclockwise. Figure 3 or Figure 4 As shown, arrow A represents that the rotation direction of the rotating rod 21 is counterclockwise, and arrow B represents that the rotation direction of the guide roller 3 is clockwise. Figure 4 When the moving direction of the buffer pad 20 is rightward, the guide roller 3 can be controlled to rotate clockwise and the rotating rod 21 can rotate counterclockwise, which is convenient for cutting the buffer pad 20. Figure 3 or Figure 4 Indicated by the arrow.

[0073] By rotating the rotating rod 21 in the opposite direction to the rotating direction of the guide roller 3, the guide roller 3 rotates counterclockwise while the rotating rod 21 rotates clockwise, or the guide roller 3 rotates clockwise while the rotating rod 21 rotates counterclockwise, it is convenient to cut the buffer pad 20.

[0074] Reference Figure 1 and Figure 2 In some embodiments, the glue laminating machine 10 also includes a guide roller 4, and the guide roller 4, the cutter assembly 2, and the guide roller 3 are arranged in sequence along the height direction of the bracket 1, and the guide roller 4 is arranged on the top of the cutter assembly 2.

[0075] The guide roller 4 is also a cylindrical roller, which mainly plays the role of guiding and tensioning. The height direction here refers to the vertical direction. Figure 2As shown by the arrow H in the middle. The specific operation is: before cutting, the complete cushion pad 20 first passes around the guide roller 4, and then extends into the gap 6 between the rotating rod 21 and the guide roller 3, and then the cutter 22 rotates in the direction of the cushion pad 20 to cut. The rotation direction of the guide roller 3 is opposite to that of the rotating rod 21, so that the cut small cushion pad is sent out.

[0076] By setting the guide roller 4, the buffer pad 20 to be cut first passes through the guide roller 4 and then extends into the gap 6 between the rotating rod 21 and the guide roller 3. The guide roller 4 plays a tensioning and guiding role, so that the buffer pad 20 will not bend during the cutting process, thereby improving the cutting accuracy.

[0077] In some embodiments, the guide roller 4 is rotatably mounted on the bracket 1 .

[0078] The guide roller 4 here can be fixedly installed on the bracket 1, and the buffer pad 20 is moved by pulling with external force, and the guide roller 4 plays a tensioning role. Of course, the guide roller 4 can also be rotatably installed on the bracket 1, so that during the movement of the buffer pad 20, the friction between the guide roller 4 and the buffer pad 20 will drive the guide roller 4 to rotate together, while reducing the friction between the guide roller 4 and the buffer pad 20, reducing the wind direction of the wear of the buffer pad 20, and the guide roller 4 can also play a guiding role at this time. Of course, the guide roller 4 can also be connected to a power component, and the guide roller 4 is driven to rotate by the power component. The buffer pad 20 is moved together by the rotation of the guide roller 4 and the friction between the guide roller 4 and the buffer pad 20, which adds some driving force to the movement of the buffer pad 20. At this time, the guide roller 4 can also play a tensioning and guiding role.

[0079] By rotatably mounting the guide roller 4 on the bracket 1 , the guide roller 4 can rotate around its own central axis during actual use, thereby playing a tensioning and guiding role.

[0080] Reference Figure 6 In some embodiments, the cutter 22 includes a first side 221 and a second side 222 that are arranged opposite to each other, and a bottom edge 223 and a bevel 224 that respectively connect the first side 221 and the second side 222, the bottom edge 223 is connected to the rotating rod 21, and the bevel connects the first side 221 and the second side 222.

[0081] The first side 221, the second side 222, the bottom 223 and the bevel 224 here describe the outer contour of the cutter 22. The cutter 22 is not a middle frame structure, but a solid structure in the middle. The first side 221 and the second side 222 are arranged opposite to each other, the bottom 223 connects the same end of the first side 221 and the second side 222, and the bevel connects the other end of the first side 221 and the second side 222, forming a closed contour. The bottom 223 is connected to the rotating rod 21, which can be welded here. The welding strength is relatively large, and the cutter 22 is not easy to fall off during the cutting process. The bevel 224 is arranged on the side away from the rotating rod 21. The setting of the bevel 224 makes the side of the cutter 22 away from the rotating rod 21 form a tip 225, that is, one end of the tangent buffer pad 20 is the tip 225. The tip 225 is used to rotate to the gap 6 and then cut the buffer pad 20, so that it is easier to cut the buffer pad 20.

[0082] The cutter 22 includes a first side edge 221, a second side edge 222, a bottom edge 223 and a bevel edge 224 which are arranged opposite to each other. The bevel edge 224 is arranged so that a tip 225 is formed on the side of the cutter 22 away from the rotating rod 21. The tip 225 is used to move toward the gap 6 to cut the buffer pad 20, making it more convenient to cut the buffer pad 20.

[0083] Reference Figure 5 and Figure 6 In some embodiments, the radial length of the second side 222 along the rotating rod 21 is greater than the length of the first side 221 , and along the rotation direction of the rotating rod 21 , the inclined surface extends from the first side 221 to the second side 222 away from the rotating rod 21 .

[0084] The length of the second side 222 along the radial direction of the rotating rod 21 is actually the height of the second side 222 relative to the outer circumference of the rotating rod 21. The length of the first side 221 along the radial direction of the rotating rod 21 is actually the height of the second side 221 relative to the outer circumference of the rotating rod 21. For the buffer pad 20 to be cut, it is the length of the cutter 22. Figure 4 If the rotating rod 21 rotates counterclockwise, the length of the second side 222 on the right side of the cutter 22 is greater than the length of the first side 221 on the left side of the cutter 22. Through the connection of the bevel 224, a sharp point 225 is formed at the top of the second side 222. In this way, during the rotation of the rotating rod 21, the sharp point of the second side 222 first contacts the buffer pad 20 and cuts off, which can reduce the contact time between the cutter 22 and the buffer pad 20 and reduce extrusion.

[0085] By setting the radial length of the second side 222 along the rotating rod 21 to be greater than the length of the first side 221, along the rotating direction of the rotating rod 21, the inclined surface extends from the first side 221 to the second side 222 away from the rotating rod 21, which is conducive to quickly cutting off the buffer pad 20.

[0086] In some embodiments, the length of the cutter 22 along the radial direction of the rotating rod 21 is smaller than the distance between the rotating rod 21 and the guide roller 3 .

[0087] The distance between the rotating rod 21 and the guide roller 3 is the height of the gap 6. The gap 6 here needs to allow the buffer pad 20 to pass through, and enough space needs to be left for the cutter 22 to rotate into the gap 6 to cut the buffer pad 20. When the cutter 22 is parallel to the line connecting the center of the rotating rod 21 and the center of the light guide roller, the height occupied by the cutter 22 in the gap 6 reaches a maximum value. At this time, enough space needs to be left for the buffer pad 20. Therefore, it is necessary to set the radial length of the cutter 22 along the rotating rod 21 to be less than the distance between the rotating rod 21 and the guide roller 3.

[0088] By limiting the maximum length of the cutter 22, sufficient space is left for the buffer pad 20 and the cutter 22 to move, so that the buffer pad 20 and the cutter 22 can buffer in the gap 6, thereby reducing the risk of jamming or chipping due to limited space.
