[0061] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] Please see Figure 1 The embodiments of this application provide a method for processing a stapler cutter, including:

[0063] S10: Obtain the three-dimensional information of the stapler cutting blade standard part.

[0064] S20, based on the three-dimensional information of the stapler cutting blade standard part, the dressing device dresses the outer contour of the first grinding wheel to obtain the second grinding wheel.

[0067] S50, the stapler cutting blade blank after sharpening is inspected to check whether the sharpening effect of the stapler cutting blade blank is qualified.

[0068] S60 uses a second fixing device to clamp the stapler cutting blade blank that has passed the edge-sharpening effect test.

[0069] S70, the stapler cutting blade blank held by the second fixing device is polished by a polishing device to obtain the stapler cutting blade.

[0070] The above-mentioned processing method for the stapler cutter first obtains the three-dimensional information of the stapler cutter standard part; then, based on the three-dimensional information of the stapler cutter standard part, the dressing device trims the outer contour of the first grinding wheel to obtain the second grinding wheel; next, the stapler cutter blank is clamped by the first fixing device; then, the stapler cutter blank is ground by the second grinding wheel to sharpen the stapler cutter blank; then, the sharpened stapler cutter blank is inspected to check whether the sharpening effect of the stapler cutter blank is qualified; next, the stapler cutter blank with qualified sharpening effect is clamped by the second fixing device; finally, the stapler cutter blank clamped by the second fixing device is polished to obtain the stapler cutter. This method can sharpen and polish the stapler cutter blank according to the three-dimensional information of the stapler cutter standard part, resulting in more consistent stapler cutters and higher processing efficiency.

[0071] In this embodiment, the three-dimensional information of the stapler cutter standard can be obtained by taking an image of the stapler cutter standard using a detection device such as a scanner or CCD camera.

[0072] Please see Figure 2 , Figure 3 and Figure 4 The first fixing device 100 includes a positioning component 10 and a clamping component 20. The clamping component 20 is detachably mounted on the positioning component 10, and a positioning space 30 is provided between the positioning component 10 and the clamping component 20 for positioning the stapler cutting blade blank 500. The positioning component 10 has a first recess 101 and a first opening 102. The first recess 101 is located on the side of the positioning component 10 opposite to the clamping component 20, and the first opening 102 penetrates the positioning component 10 and communicates with the first recess 101. The clamping component 20 has a second recess 201 and a second opening 202. The second recess 201 is located on the side of the clamping component 20 opposite to the positioning component 10, and the second opening 202 penetrates the clamping component 20 and communicates with the second recess 201. The second opening 202 is directly opposite to the first opening 102. The first exposed opening 102 and the second exposed opening 202 are connected to the positioning space 30. The first exposed opening 102 and the second exposed opening 202 are used to allow the grinding end 510 of the stapler cutting blade blank 500 to extend out.

[0073] Please see Figure 2 , Figure 3 and Figure 4The first recess 101 has a first recess bottom wall 1011, and the second recess 201 has a second recess bottom wall 2011. Both the first recess bottom wall 1011 and the second recess bottom wall 2011 have opposing first ends 1011a and second ends 1011b. A first exposed opening 102 is provided corresponding to the first end 1011a of the first recess bottom wall 1011. The first recess bottom wall 1011 is inclined downwards from its corresponding second end 1011b toward its corresponding first end 1011a. The second exposed opening 202 is provided corresponding to the first end 1011a of the second recess bottom wall 2011. The second recess bottom wall 2011 is inclined downwards from its corresponding second end 1011b toward its corresponding first end 1011a.

[0074] When the second grinding wheel passes through the first clearance groove 101 to grind the cutting edge 520 of the stapler cutting tool blank 500, the second grinding wheel enters from the second end 1011b of the first clearance groove 101 and grinds the cutting edge 520 at the first exposure opening 102. When the second grinding wheel passes through the second clearance groove 201 to grind the cutting edge 5201 of the cutting edge 520 of the stapler cutting tool blank 500, the second grinding wheel enters from the first end 1011a of the second clearance groove 201 and grinds the cutting edge 520 at the second exposure opening 202.

[0075] Please refer to the following: Figure 5 , Figure 6 and Figure 7 The positioning component 10 has a first positioning groove 121 on the side facing the clamping component 20, and the clamping component 20 has a second positioning groove 221 on the side facing the positioning component 10. The second positioning groove 221 is directly opposite to the first positioning groove 121, and the first positioning groove 121 and the second positioning groove 221 together enclose at least a portion of the positioning space 30.

[0076] The positioning space 30 also includes a gap (not shown) between the clamping assembly 20 and the positioning assembly 10, which communicates with the first positioning groove 121 and the second positioning groove 221. There can be multiple positioning spaces 30, and correspondingly, there can also be multiple first positioning grooves 121 and multiple second positioning grooves 221, with each first positioning groove 121 and each second positioning groove 221 corresponding one-to-one. Thus, the first fixing device 100 can simultaneously clamp and position multiple stapler cutting blade blanks 500, thereby facilitating the simultaneous grinding of the grinding edges 520 of multiple stapler cutting blade blanks 500 by multiple second grinding wheels, thereby improving the efficiency of grinding the workpiece 500.

[0077] The bottom of the first positioning groove 121 is further provided with a positioning protrusion 1211, which is used to insert the positioning workpiece 500. For example, the stapler cutting blade blank 500 is provided with an insertion hole 540. When the stapler cutting blade blank 500 is positioned in the first positioning groove 121 and the second positioning groove 221, the positioning protrusion 1211 is inserted into the insertion hole 540 to position the stapler cutting blade blank 500.

[0078] Please refer to the reference again. Figure 5 , Figure 6 and Figure 7 The positioning component 10 includes a first wear-resistant structure 13 near the first exposed opening 102, and the first exposed opening 102 penetrates the first wear-resistant structure 13. The clamping component 20 includes a second wear-resistant structure 23 near the second exposed opening 202, and the second exposed opening 202 penetrates the second wear-resistant structure 23.

[0079] Please refer to the reference again. Figure 5 and Figure 6 The positioning component 10 includes a positioning element 11 and a support element 12. The clamping component 20 is detachably mounted on the positioning element 11, and the support element 12 is located on the side of the positioning element 11 facing the clamping component 20. The positioning element 11 is a first wear-resistant structure 13. The first clearance groove 101 includes two connected parts. One part of the first clearance groove 101 is formed on the side of the positioning element 11 opposite to the clamping component 20, and the other part of the first clearance groove 101 is formed on the support element 12. A first exposed opening 102 penetrates the portion between the side of the support element 12 facing the clamping component 20 and the bottom wall of the first clearance groove 101.

[0080] Please refer to the reference again. Figure 5 and Figure 6 The positioning member 11 has a first mounting groove 111 on the side facing the clamping assembly 20. The first mounting groove 111 is located at the end of the positioning member 11, and the support member 12 is installed in the first mounting groove 111.

[0081] The positioning member 11 also has a mounting groove 112 on the side facing the clamping assembly 20, and the mounting groove 112 is located in the middle of the positioning member 11. The positioning assembly 10 also includes a stop member 14, a clamping member 15 and an elastic member 16. The stop member 14 is disposed in the mounting groove 112 and extends out of the positioning member 11 on the side facing the clamping assembly 20. The clamping member 15 is slidably disposed in the mounting groove 112 and can move relative to the stop member 14. The elastic member 16 can be a spring. The elastic member 16 is disposed in the mounting groove 112, and the two ends of the elastic member 16 are respectively connected to the inner wall of the mounting groove 112 and the side of the clamping member 15 away from the stop member 14. The elastic member 16 is used to drive the clamping member 15 to press the stapler cutting blade blank 500 against the stop member 14.

[0082] When the stapler cutter blank 500 is placed on the positioning assembly 10, the clamping member 15 is first moved away from the abutment member 14. Then, the stapler cutter blank 500 is placed between the clamping member 15 and the abutment member 14, and the stapler cutter blank 500 is positioned in the first positioning groove 121. After that, the clamping member 15 is released, and the elastic member 16 drives the clamping member 15 to press the stapler cutter blank 500 against the abutment member 14. In this way, the positioning assembly 10 can also clamp and position the stapler cutter blank 500, thereby improving the accuracy of positioning the stapler cutter blank 500.

[0083] Please refer to the following: Figure 5 and Figure 7 The clamping assembly 20 includes a clamping member 21 and a guide member 22. The clamping member 21 is detachably mounted on the positioning member 11, and the guide member 22 is located on the side of the clamping member 21 facing the positioning member 11. The guide member 22 is directly opposite the support member 12, and the guide member 22 is the second wear-resistant structure 23. The second clearance groove 201 includes two connected parts. One part of the second clearance groove 201 is formed on the side of the clamping member 21 away from the positioning member 11, and the other part of the second clearance groove 201 is formed on the guide member 22. The second exposed opening 202 penetrates the portion between the side of the guide member 22 facing the positioning assembly 10 and the bottom wall of the second clearance groove 201.

[0084] Please refer to the reference again. Figure 5 and Figure 7 The clamping member 21 has a second assembly groove 211 on the side facing the positioning component 10. The second assembly groove 211 is located at the end of the clamping member 21 and is directly opposite to the first assembly groove 111. The guide member 22 is installed in the second assembly groove 211.

[0085] The clamping member 21 is also provided with a clearance groove 213 on the side facing the positioning component 10. The clearance groove 213 is positioned opposite the blocking member 14 and is used to avoid the blocking member 14 and the clamping member 15.

[0086] The support member 12 has a first limiting groove 122 on the side facing the guide member 22, and the guide member 22 has a second limiting groove 222 on the side facing the support member 12. The second limiting groove 222 and the first limiting groove 122 are arranged opposite each other. The first limiting groove 122 and the second limiting groove 222 are respectively used to cooperate with the structural limiting of the two sides of the end 510 to be ground.

[0087] For example, such as Figure 4 As shown, the end 510 to be ground of the stapler cutting blade blank 500 has limiting protrusions 530 on both sides. When the first fixing device 100 clamps the workpiece 500, the first limiting groove 122 and the second limiting groove 222 respectively cooperate with the limiting protrusions 530 on both sides of the end 510 to be ground to restrict the movement of the end 510 to be ground.

[0088] Please refer to the reference again. Figure 5 and Figure 7 The positioning component 10 has a limiting part 113 on the side facing the clamping component 20, and the clamping component 20 has a limiting engagement part 212 on the side facing the positioning component 10. The limiting engagement part 212 and the limiting part 113 are inserted and engaged to position the clamping component 20 relative to the positioning component 10.

[0089] For example, the limiting part 113 is a positioning pin inserted into the side of the positioning member 11 facing the clamping component 20, and the limiting mating part 212 is a positioning hole opened on the clamping member 21. The positioning pin and the positioning hole are engaged to position the clamping component 20 relative to the positioning component 10.

[0090] Please refer to the reference again. Figure 5 and Figure 7 The positioning assembly 10 includes a first cutting edge 103 located at the first exposed opening 102, the first cutting edge 103 being disposed around the first exposed opening 102. The clamping assembly 20 includes a second cutting edge 203 located at the second exposed opening 202, the second cutting edge 203 being disposed around the second exposed opening 202. The shapes of both the first cutting edge 103 and the second cutting edge 203 are arc-shaped to conform to the shape of the grinding edge 520 of the workpiece 500.

[0091] The first fixing device 100 also includes a locking member 40, which passes through the clamping assembly 20 and is connected to the positioning assembly 10.

[0092] For example, the positioning member 11 has a first threaded hole 114, the clamping member 21 has a second threaded hole 214, and the locking member 40 can be a bolt. The locking member 40 passes through the second threaded hole 214 and the first threaded hole 114 to lock the clamping assembly 20 and the positioning assembly 10.

[0093] In some embodiments, before sharpening the cutting edge 520 of the stapler cutting blade blank 500 using a grinding wheel, the grinding wheel needs to be ground and corrected; wherein, the step of using a dressing device to adjust the outer contour of the first grinding wheel based on the three-dimensional information of the stapler cutting blade standard part to obtain the second grinding wheel includes:

[0094] S21, Based on the three-dimensional information of the stapler cutting blade standard part, confirm the first grinding path.

[0095] S22, based on the first grinding path, the dressing device dresses the outer contour of the first grinding wheel to obtain the second grinding wheel.

[0096] After obtaining the three-dimensional information of the stapler cutting blade standard part, the outline and size information of the stapler cutting blade standard part can be obtained. Then, the first grinding path can be set by means of software simulation, such as a grinding path that moves from the top to the lower left or from the lower right, to process the two edges of the stapler cutting blade blank. Then, according to the first grinding path, the dressing device can dress the outer contour of the first grinding wheel to obtain the second grinding wheel.

[0097] like Figure 8 As shown, the dressing device 200 for grinding and dressing grinding wheels includes a machining spindle 210, a connector 220, a dressing assembly 230, and a controller 240. The connector 220 is detachably connected to the machining spindle 210, and a first grinding wheel 201 is mounted on the connector 220. Two grinding wheels can be mounted on the connector 220. The dressing assembly 230 includes a drive component 231 and a dressing component 232. The drive component 231 is located on one side of the machining spindle 210 and connected to the dressing component 232. The controller 240 is electrically connected to both the machining spindle 210 and the drive component 231. The controller 240 controls the machining spindle 210 to move the first grinding wheel 201 relative to the dressing component 232, and controls the drive component 231 to drive the dressing component 232 to rotate, so that the dressing component 232 dresses the outer contour of the first grinding wheel 201 to obtain a second grinding wheel 204. For example, the machining spindle 210 can be a machine tool spindle. In some embodiments, prior to the step of sharpening the anastomosis cutter blank by grinding it with a second grinding wheel, the processing method further includes:

[0098] S31, obtain the coordinates of the stapler cutting blade blank on the first fixing device.

[0099] S32, based on the coordinates of the anastomosis device cutting blade blank, determine the second grinding path, wherein the second grinding path is the grinding path of the second grinding wheel.

[0100] S33, based on the second grinding path, the second grinding wheel is moved along the first grinding path toward the first fixing device where the anastomosis cutter blank is not placed, in order to determine whether there is interference between the second grinding wheel and the first fixing device.

[0101] Before the second grinding wheel sharpens the product (anastomosis device cutting blade blank), the product coordinates and the specific position of the cutting edge to be sharpened are obtained to determine the grinding path. Then, a trial run is performed according to the grinding path to confirm whether there is any interference between the grinding wheel and the product fixture (first fixing device). If there is interference, the grinding path is adjusted. If there is no interference, the second grinding wheel can start sharpening the product cutting edge according to the preset grinding path.

[0102] Please refer to it again. Figure 4The end 510 of the stapler cutting blade blank 500 to be ground has a first detection surface 5101, a second detection surface 5102 and a third detection surface 5103. The first detection surface 5101 is the end face of the end 510 to be ground, the second detection surface 5102 is the side of the limiting protrusion 530 near the first exposure port 102 or the second exposure port 202, and the third detection surface 5103 is the side of the end 510 to be ground that abuts against the bottom wall 1011 of the first groove or the bottom wall 2011 of the second groove. When grinding the cutting edge 520 of the stapler cutting tool blank 500, a probe (not shown) can be used to detect the first detection surface 5101, the second detection surface 5102, and the third detection surface 5103 of the stapler cutting tool blank 500 to obtain the processing coordinates. Based on the processing coordinates, the processing spindle 210 can drive the second grinding wheel 204 to move along the second grinding path toward the first fixing device 100 where the stapler cutting tool blank 500 is not placed, in order to determine whether there is interference between the second grinding wheel 102 and the first fixing device 100. If there is interference, the second grinding path is adjusted until there is no interference between the second grinding wheel 204 and the first fixing device 100. If there is no interference, the processing spindle 210 drives the second grinding wheel 102 to grind the stapler cutting tool blank 500 placed on the first fixing device 100 along the second grinding path.

[0103] In some embodiments, the processing method further includes:

[0104] S80, based on the fact that the stapler cutter obtained after polishing by the polishing device meets the standard, the contour information of the second grinding wheel is obtained.

[0105] S90, based on the contour information of the second grinding wheel, the dressing device dresses the outer contour of the third grinding wheel to obtain a fourth grinding wheel with the same outer contour as the second grinding wheel, and the hardness of the fourth grinding wheel is greater than that of the second grinding wheel.

[0106] S100 causes the fourth grinding wheel to grind multiple stapler cutting blade blanks in sequence, thereby sharpening the multiple stapler cutting blade blanks in sequence.

[0107] To save costs, the grinding process is divided into two stages. The first stage is the prototyping stage, which uses a low-hardness first grinding wheel, such as a green silicon carbide grinding wheel (201). After grinding, a second grinding wheel 204 is obtained. Then, the machining spindle 210 drives the second grinding wheel 204 to sharpen the anastomosis cutter blank 500. When the anastomosis cutter blank 500 obtained after sharpening and polishing meets the standard, such as the number of burrs and the outline structure size on the anastomosis cutter blank 500 meeting the standard, the outline information of the second grinding wheel 204 is obtained, and the second stage, namely the mass production stage, is entered. At this time, the outer outline of the third grinding wheel with higher hardness is dressed. The third grinding wheel is, for example, a cubic boron nitride (CBN) grinding wheel, thereby obtaining a fourth grinding wheel. Subsequently, the machining spindle 210 drives the fourth grinding wheel to grind multiple anastomosis cutter blanks 500 in sequence, so as to sharpen multiple anastomosis cutter blanks 500 in sequence, thereby realizing the mass production of anastomosis cutter blanks 500.

[0108] In some embodiments, before sequentially sharpening multiple stapler cutting blade blanks by having a fourth grinding wheel grind multiple stapler cutting blade blanks, the processing method includes:

[0109] S110 causes the fourth grinding wheel to grind a preset number of stapler cutting tool blanks under different grinding conditions and at different grinding frequencies, thereby sharpening the preset number of stapler cutting tool blanks.

[0110] S120 determines the optimal grinding conditions and optimal grinding frequency based on the cutting data of a preset number of stapler cutting tool blanks.

[0111] S130, based on optimal grinding conditions and optimal grinding frequency, enables the fourth grinding wheel to grind the subsequent anastomosis cutter blank, thereby sharpening the subsequent anastomosis cutter blank.

[0112] Specifically, the machining spindle 210 can drive the fourth grinding wheel to grind a preset number of anastomosis cutter blanks 500 under different grinding conditions and frequencies, thereby sharpening the preset number of anastomosis cutter blanks 500, for example, 100. Afterwards, the sharpened anastomosis cutter blanks 500 can be detected by means of a detection instrument such as a CCD camera taking pictures and a processor processing, to obtain the sharpening data of the anastomosis cutter blanks 500, that is, the dimensional values ​​of the anastomosis cutter blanks 500 at various points. Then, by comparing the dimensional values ​​of the anastomosis cutter blanks 500 obtained after testing with the dimensional values ​​of the standard anastomosis cutter, the optimal grinding conditions and the optimal grinding frequency can be determined. Finally, based on the optimal grinding conditions and the optimal grinding frequency, the machining spindle 210 can drive the fourth grinding wheel to grind subsequent anastomosis cutter blanks 500.

[0113] In some embodiments, the processing method further includes:

[0114] S140 periodically acquires information on the dimensional and contour changes of the anastomosis cutter blank after sharpening.

[0115] S150 adjusts the grinding frequency of the fourth grinding wheel based on the size and contour changes of the stapler cutting tool blank.

[0116] To ensure the consistency of the stapler cutting tool blank 500 after sharpening, the size and contour change information of the stapler cutting tool blank 500 after sharpening can be obtained periodically by means of CCD camera photography and processor processing, for example, the size and contour change information of the stapler cutting tool blank 500 is obtained every 5 processed. Then, based on the size and contour change information of the stapler cutting tool blank 500 after sharpening, the grinding frequency of the fourth grinding wheel is adaptively increased or decreased so that the size and contour of the stapler cutting tool blank 500 after sharpening meet the standard.

[0117] In some embodiments, the processing method further includes:

[0118] S160, obtain the dimensional change information of the fourth grinding wheel.

[0119] S170, based on the dimensional change information of the fourth grinding wheel, confirm the wear value of the fourth grinding wheel.

[0120] S180, based on the wear value of the fourth grinding wheel, adjust the first grinding path and obtain the third grinding path.

[0121] S190, based on the third grinding path, causes the fourth grinding wheel to grind the subsequent anastomosis cutter blank, thereby sharpening the subsequent anastomosis cutter blank.

[0122] The fourth grinding wheel will experience wear during use. When the worn fourth grinding wheel grinds the anastomosis cutter blank 500 along the first grinding path, the dimensions of the blank will deviate, resulting in lower precision after sharpening. To avoid this problem, the dimensional change information of the fourth grinding wheel can be periodically acquired through methods such as CCD camera photography and processor processing to determine its wear value. The processor then readjusts the first grinding path of the fourth grinding wheel based on the wear value, thus obtaining a third grinding path. Finally, the machining spindle 210 drives the fourth grinding wheel to move along the third grinding path to grind subsequent anastomosis cutter blanks 500, thereby sharpening them.

[0123] In some embodiments, after the stapler cutting blade blank 500 is sharpened and the sharpening effect is tested to be qualified, the stapler cutting blade blank 500 also needs to be polished to make the product cutting edge smooth and burr-free, meeting the quality requirements; please refer to Figure 9 and Figure 10 Before polishing the stapler cutter, a special fixture is also required, such as... Figure 9 and Figure 10 The second fixing device 300 shown includes a positioning component 311 and a cover component 312. The cover component 312 is detachably covered by the positioning component 311. A limiting space 3114 is provided between the cover component 312 and the positioning component 311. The limiting space 3114 is used to position the anastomosis device cutting blade blank 500 after sharpening. The cover component 312 is provided with a machining avoidance groove 3123 and a machining protrusion 3124. The machining avoidance groove 3123 is located on the side of the cover component 312 away from the positioning component 311. The machining protrusion 3124 penetrates the cover component 312 and communicates with the machining avoidance groove 3123 and the limiting space 3114. The machining protrusion 3124 is also used to allow the end 510 of the anastomosis device cutting blade blank 500 to be ground to protrude.

[0124] The second fixing device 300 can be mounted on the robotic arm, thereby enabling the second fixing device 300 to move relative to the polishing device. When grinding the anastomosis cutter blank 500, the anastomosis cutter blank 500 is first positioned in the limiting space 3114, and the end 510 of the anastomosis cutter blank 500 to be ground extends out of the processing exposure opening 3124; then the robotic arm drives the second fixing device 300 to move along the grinding path relative to the polishing device, and the polishing cloth wheel of the polishing device moves through the processing avoidance groove 3123 to the processing exposure opening 3124 to grind the cutting edge 520 of the anastomosis cutter blank 500.

[0125] The machining clearance groove 3123 has a machining groove bottom wall 3123c, the machining groove bottom wall 3123c has a third end 3123d and a fourth end 3123e opposite to each other, the machining exposure opening 3124 is set corresponding to the third end 3123d, and the machining groove bottom wall 3123c is set inclined downward from the fourth end 3123e toward the third end 3123d.

[0126] When the polishing cloth wheel passes through the processing clearance groove 3123 to grind the cutting edge 520 of the stapler cutting tool blank 500, the polishing cloth wheel enters from the fourth end 3123e of the bottom wall 3123c of the processing groove and grinds the cutting edge 520 at the processing protrusion 3124.

[0127] The positioning component 311 includes a limiting member 3111, and a cover assembly 312 is detachably mounted on the limiting member 3111. The limiting member 3111 has a limiting groove 3111a on the side facing the cover assembly 312. The limiting groove 3111a and the cover assembly 312 enclose a limiting space 3114, and the exposed processing opening 3124 communicates with the limiting groove 3111a. The limiting groove 3111a facilitates the storage of the positioning stapler cutting blade blank 500. By forming the limiting space 3114 with the cover assembly 312, when the cover assembly 312 is mounted on the limiting member 3111, the cover assembly 312 compresses and limits the stapler cutting blade blank 500, thereby improving the accuracy of the second fixing device 100 in clamping the stapler cutting blade blank 500.

[0128] The bottom of the limiting groove 3111a is also provided with a limiting protrusion 3111b, which is used to insert the positioning stapler cutting blade blank 500.

[0129] The positioning assembly 311 also includes a support body 3112, which is disposed on the side of the limiting member 3111 facing the cover assembly 312. The support body 3112 has a support surface 3112a, which is directly opposite to the machining protrusion 3124. The support surface 3112a is used to support the part of the end 510 to be ground located in the machining protrusion 3124.

[0130] For example, the limiting member 3111 has a receiving groove 3111c on the side facing the cover assembly 312. The receiving groove 3111c is located at one end of the limiting groove 3111a and communicates with the limiting groove 3111a. The support body 3112 is disposed in the receiving groove 3111c.

[0131] A clearance groove 3112b is provided on the side of the support body 3112 facing the cover assembly 312. The clearance groove 3112b is located in the extension direction of the machining avoidance groove 3123, wherein the extension direction of the machining avoidance groove 3123 is inclined. Since the grinding edge 520 of the anastomosis cutter blank 500 is inclined, when the polishing wheel polishes the grinding edge 520, the polishing wheel is prone to contact with the support body 3112, resulting in incomplete grinding of the grinding edge 520. By providing the clearance groove 3112b, and the clearance groove 3112b being located in the extension direction of the machining avoidance groove 3123, when the polishing wheel polishes the grinding edge 520 of the anastomosis cutter blank 500, the clearance groove 3112b avoids the polishing wheel, thereby enabling the polishing wheel to grind the grinding edge 411, thus improving the accuracy of grinding the anastomosis cutter blank 500.

[0132] The support body 3112 is also provided with a receiving groove 3112c on the side facing the cover assembly 312. The receiving groove 3112c is located on the side of the relief groove 3112b. The receiving groove 3112c is used to cooperate with the structural limit of the end to be ground 510 away from the processing exposure opening 3124.

[0133] The positioning component 311 has a limiting portion 3111d on the side facing the cover pressing component 312, and the cover pressing component 312 has a limiting mating portion 3121b on the side facing the positioning component 311. The limiting mating portion 3121b and the limiting portion 3111d are inserted and mated to position the cover pressing component 312 relative to the positioning component 311.

[0134] Please see also Figure 11 The portion of the cover assembly 312 near the processing opening 3124 includes a wear-resistant structure, through which the processing opening 3124 penetrates. Since the polishing cloth wheel grinds the cutting edge 520 of the stapler cutting tool blank 500 at high frequencies, it also grinds the cover assembly 312. By providing a wear-resistant structure, the cover assembly 312 can withstand the high-frequency grinding of the polishing cloth wheel, thereby improving its service life.

[0135] The cover assembly 312 includes a cover member 3121 and a guide member 3122. The cover member 3121 is detachably covered by the positioning assembly 311. The guide member 3122 is located on the side of the cover member 3121 facing the positioning assembly 311 and has a wear-resistant structure. The machining clearance groove 3123 includes a first sub-groove 3123a and a second sub-groove 3123b that are connected to each other. The first sub-groove 3123a is located on the side of the cover member 3121 away from the positioning assembly 311. The second sub-groove 3123b is located on the guide member 3122. The machining protrusion 3124 penetrates the portion between the side of the guide member 3122 facing the positioning assembly 311 and the bottom wall of the second sub-groove 3123b away from the end of the first sub-groove 3123a.

[0136] For example, the cover member 3121 has an assembly groove 3121a on the side facing the positioning component 311, the assembly groove 3121a is arranged opposite to the receiving groove 3111c, and the guide member 3122 is installed in the assembly groove 3121a.

[0137] The exposed opening 3124 also extends through the guide 3122 and the cover 3121 along the closing direction of the cover assembly 312.

[0138] The cover assembly 312 includes a cutting edge 3122a located at the processing opening 3124. The cutting edge 3122a is arranged around the processing opening 3124 and is arc-shaped to conform to the grinding edge 520 of the cutting tool blank 500 of the stapler.

[0139] The second fixing device 300 further includes a locking assembly 313. The locking assembly 313 includes a locking drive member 3131 and a clamping member 3133. The locking drive member 3131 is disposed on the positioning assembly 311 and has a telescopic drive shaft 3132. The drive shaft 3132 passes through the positioning assembly 311 and the cover pressing assembly 312 and extends to the side of the cover pressing assembly 312 opposite to the positioning assembly 311. The clamping member 3133 is connected to the end of the drive shaft 3132 near the cover pressing assembly 312. The clamping member 3133 is used to press the cover pressing assembly 312 against the positioning assembly 311 under the drive of the drive shaft 3132.

[0140] The positioning assembly 311 also includes a connecting seat 3113, which is located on the side of the limiting member 3111 opposite to the cover pressing assembly 312. The connecting seat 3113 is used to connect with the robotic arm. A locking drive member 3131 is located on the connecting seat 3113. The limiting member 3111 has a through hole 3111e, and the cover pressing member 3121 has a stop groove 3121c on the side opposite to the limiting member 3111. The bottom of the stop groove 3121c has an oblong hole 3121e. The locking drive member 3131 is a lifting rotary cylinder. The clamping member 3133 is perpendicularly connected to the drive shaft 3132 of the locking drive member 3131, and the size of the clamping member 3133 is approximately the same as the size of the oblong hole 3121e.

[0141] When the cover assembly 312 presses onto the positioning assembly 311, the clamping member 3133 extends into the stop groove 3121c through the oblong hole 3121e. At this time, the locking drive member 3131 drives the clamping member 3133 to rotate by a preset angle, such as 90 degrees, through the drive shaft 3132. Then, the locking drive member 3131 drives the clamping member 3133 to move towards the positioning assembly 311 through the drive shaft 3132. The clamping member 3133 presses the cover assembly 312 against the positioning assembly 311, thereby improving the convenience of locking the cover assembly 312 and the positioning assembly 311. After the grinding edge 520 of the stapler cutting blade blank 500 is ground, the locking drive member 3131 drives the clamping member 3133 to rotate and return to its original position through the drive shaft 3132, thereby facilitating the removal of the cover assembly 312 from the positioning assembly 311.

[0142] After the second fixing device 300 fixes the stapler cutting blade blank 500 to be polished, the product can be polished using a polishing device, which includes a polishing wheel (such as...). Figure 12 As shown in the figure, the polishing wheel needs to be waxed before polishing each product.

[0143] In some embodiments, the step of obtaining a stapler cutter by polishing the stapler cutter blank held by the second fixing device using a polishing device includes:

[0144] S71, drives the waxing component to move toward the polishing device so that the waxing component waxes the polishing device; the waxing component may include a waxing fixture and a wax block, the waxing fixture is used to fix the wax block and make the wax block extend a certain distance to facilitate waxing the polishing wheel; the waxing component can be driven to the corresponding position by a robotic arm or robotic hand to wax the polishing wheel.

[0145] S72, the sharpened stapler cutting blade blank is moved toward the polishing device so that the polishing device polishes the stapler cutting blade blank at a preset angle and pressure, thereby obtaining the stapler cutting blade; wherein the stapler cutting blade blank 500 to be polished is fixed by the second fixing device 300, and can be held and driven to the polishing position by a robotic arm or robotic hand, so as to facilitate the polishing device to polish the product.

[0146] The waxing component can be fixed to the robotic arm. The exposed length of the wax block is adjustable, but manual adjustment is required. For each stapler cutter blank processed, the waxing component automatically performs waxing compensation feed. When the wax block wears down to approximately 35mm, the waxing component will give a signal, requiring timely adjustment of the wax block length. The second fixing device 300 effectively protects the stapler cutter blank 500 from over-polishing. The robotic arm clamps the second fixing device 300 according to a pre-programmed polishing trajectory, allowing the polishing device to polish the stapler cutter blank 500 at a preset angle and pressure. For each stapler cutter blank 500 processed, the robotic arm automatically performs compensation feed.

[0147] The polishing apparatus also includes a scraper assembly, which is connected to a robotic arm that moves the scraper assembly. See also... Figure 12 The polishing wheel 400 of the polishing device includes a polishing clamp 410 and a polishing cloth wheel 420 clamped by the polishing clamp 410. Both the polishing clamp 410 and the polishing cloth wheel 420 are circular and concentric. The diameter of the polishing cloth wheel 420 is larger than the diameter of the polishing clamp 410. In some embodiments, the processing method further includes:

[0148] S73, the polishing wheel of the polishing device polishes a preset number of stapler cutting blade blanks, causing the robotic arm to move the scraper assembly toward the polishing device so that the scraper assembly scrapes off a preset thickness of polishing layer on the polishing cloth wheel of the polishing device.

[0149] S74, based on the waxing component scraping off the polishing cloth wheel of the polishing device with a preset thickness of polishing layer, so that the polishing cloth wheel with the preset thickness of polishing layer scraped off polishes the subsequent stapler cutting blade blank.

[0150] When the polishing cloth wheel 420 polishes a preset number of stapler cutter blanks 500, for example, 5, too many abrasive grains fall off the polishing cloth wheel 420, rendering it unusable. At this point, the scraper assembly can scrape off a preset thickness of polishing layer on the polishing cloth wheel 420, for example, 1 mm, and a new polishing cloth wheel 420 can be obtained, i.e., a polishing cloth wheel 420 with the preset thickness of polishing layer scraped off. The new polishing cloth wheel 420 has more abrasive grains on its outer circumference and can continue to polish the stapler cutter blanks 500.

[0151] Please continue reading Figure 8 The detection device 600 includes a sliding member 610 and a detection member 620. The sliding member 610 is disposed on one side of the machining spindle 210 and slidably connected to the machining spindle 210 in the direction pointing from the machining spindle 210 to the connector 220. The detection member 620 is disposed on the side of the sliding member 610 away from the machining spindle 210 and connected to the sliding member 610. The detection member 620 is used to slide along the direction pointing from the machining spindle 210 to the connector 220 under the drive of the sliding member 610 to detect different processing areas of the stapler cutting blade blank 500. Exemplarily, the sliding member 610 can be any sliding part, sliding body, or similar sliding block that can drive the detection member 620 to slide, such as a sliding plate connected to a cylinder. The detection member 620 can be any detection part, detection body, or similar detection rod that can detect the stapler cutting blade blank 500, such as a detection probe, probe, and / or CCD.

[0152] Please see Figure 13 The embodiments of this application also provide a processing device 1000 for a stapler cutting blade, including a detection device 700, a trimming device 200, a first fixing device 100, a detection device 600, a second fixing device 300, a polishing device 401, and a processing chip 800. The processing chip 800 is electrically connected to the detection device 700, trimming device 200, first fixing device 100, first grinding device, detection device 600, second fixing device 300, and polishing device 401 respectively, and controls them to perform corresponding operations.

[0153] The detection device 700 is used to acquire three-dimensional information of the stapler cutter standard part. The dressing device 200 is used to dress the outer contour of the first grinding wheel based on the three-dimensional information of the stapler cutter standard part to obtain the second grinding wheel. The first fixing device 100 is used to clamp the stapler cutter blank 500. The dressing device 200 is also used to grind the stapler cutter blank 500 with the second grinding wheel to sharpen the stapler cutter blank 500. The detection device 600 is used to detect the sharpened stapler cutter blank 500 to detect whether the sharpening effect of the stapler cutter blank 500 is qualified. The second fixing device 300 is used to clamp the stapler cutter blank 500 that has passed the sharpening effect detection. The polishing device 401 is used to polish the stapler cutter blank 500 clamped by the second fixing device 300 to obtain the stapler cutter.

[0154] The aforementioned processing equipment 1000 for the stapler cutter first acquires the three-dimensional information of the stapler cutter standard part through the detection device 700; then, based on the three-dimensional information of the stapler cutter standard part, the dressing device 200 trims the outer contour of the first grinding wheel to obtain the second grinding wheel; then, the stapler cutter blank 500 is clamped by the first fixing device 100; next, the dressing device 200 also uses the second grinding wheel to grind the stapler cutter blank 500 to sharpen the stapler cutter blank 500; then, the sharpened stapler cutter blank 500 is inspected by the detection device 600. The stapler cutting blade blank 500 is inspected to check whether the sharpening effect of the stapler cutting blade blank 500 is qualified; then, the stapler cutting blade blank 500 that has passed the sharpening effect inspection is clamped by the second fixing device 300; finally, the stapler cutting blade blank 500 clamped by the second fixing device 300 is polished by the polishing device 401, thereby obtaining the stapler cutting blade. The stapler cutting blade blank 500 can be sharpened and polished according to the three-dimensional information of the stapler cutting blade standard part, which can make the obtained stapler cutting blade more consistent and the processing efficiency is high.
