[0066] Among them, after obtaining the three-dimensional information of the stapler cutting knife standard part, the outer contour and size information of the stapler cutting knife standard part can be obtained, and then the first grinding path can be set by, for example, software simulation, such as a grinding path moving from the top to the lower left or to the lower right, to process the two edges of the stapler cutting knife blank; then, according to the first grinding path, the dressing device can be used to dress the outer contour of the first grinding wheel to obtain the second grinding wheel.

[0067] like Figure 8 As shown, the dressing device 200 for grinding and correcting a grinding wheel comprises a machining spindle 210, a connecting member 220, a dressing assembly 230 and a controller 240, wherein the connecting member 220 is detachably connected to the machining spindle 210, and the first grinding wheel 201 is mounted on the connecting member 220, wherein two grinding wheels can be mounted on the connecting member 220. The dressing assembly 230 comprises a driving member 231 and a dressing member 232, wherein the driving member 231 is arranged on one side of the machining spindle 210 and connected to the dressing member 232. The controller 240 is electrically connected to the machining spindle 210 and the driving member 231 respectively, and the controller 240 is used to control the machining spindle 210 to drive the first grinding wheel 201 to move relative to the dressing member 232, and control the driving member 231 to drive the dressing member 232 to rotate, so that the dressing member 232 dresses the outer contour of the first grinding wheel 201 to obtain the second grinding wheel 204. Exemplarily, the machining spindle 210 can be a machine tool spindle. In some embodiments, before the step of grinding the stapler cutting blade blank with the second grinding wheel to sharpen the stapler cutting blade blank, the processing method further includes: S31, obtaining the coordinates of the stapler cutting blade blank on the first fixing device.

[0068] S32, determining a second grinding path based on the coordinates of the stapler cutting blade blank, wherein the second grinding path is a grinding path of the second grinding wheel.

[0069] S33, based on the second grinding path, moving the second grinding wheel along the first grinding path toward the first fixing device where no stapler cutting blade blank is placed, to determine whether interference occurs between the second grinding wheel and the first fixing device.

[0070] Before the second grinding wheel sharpens the product (stapler cutting blade blank), the product coordinates and the specific position of the product's cutting edge to be sharpened are first obtained to determine the grinding path, and then a trial run is performed according to the grinding path to confirm whether there is 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.

[0071] Please refer again Figure 4The end 510 to be ground of the stapler cutting knife blank 500 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 surface of the end 510 to be ground, the second detection surface 5102 is the side of the limiting protrusion 530 close to 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 and abuts against the first groove bottom wall 1011 or the second groove bottom wall 2011.

If interference occurs, the second grinding path is adjusted until there is no interference between the second grinding wheel 204 and the first fixing device 100. If no interference occurs, the processing spindle 210 drives the second grinding wheel 102 to grind the stapler cutting knife blank 500 placed on the first fixing device 100 along the second grinding path.

[0072] In some embodiments, the processing method further comprises: S80, based on the fact that the stapler cutting blade obtained after polishing by the polishing device meets the standard, profile information of the second grinding wheel is obtained.

[0073] S90, based on the profile information of the second grinding wheel, enabling the dressing device to dress the outer profile of the third grinding wheel to obtain a fourth grinding wheel having the same outer profile as the second grinding wheel, wherein the hardness of the fourth grinding wheel is greater than that of the second grinding wheel.

[0074] S100, enabling the fourth grinding wheel to grind a plurality of stapler cutting blade blanks in sequence, so as to sharpen the plurality of stapler cutting blade blanks in sequence.

[0075] In order to save costs, the grinding of the grinding wheel is divided into two stages. The first stage is the proofing stage, that is, the first grinding wheel 201 with lower hardness is used for grinding, such as Green Silicon Carbide Wheel), after grinding, a second grinding wheel 204 can be obtained, and then the processing spindle 210 drives the second grinding wheel 204 to sharpen the stapler cutting knife blank 500. When the stapler cutting knife blank 500 obtained after sharpening and polishing meets the standard, for example, the number of burrs and the contour structure size on the stapler cutting knife blank 500 meet the standard, the contour information of the second grinding wheel 204 is obtained, and the second stage, that is, the mass production stage, is entered. At this time, the outer contour of the third grinding wheel with higher hardness is trimmed, and the third grinding wheel is, for example, a cubic boron nitride (CBN) grinding wheel, so as to obtain a fourth grinding wheel, and then the processing spindle 210 drives the fourth grinding wheel to grind multiple stapler cutting knife blanks 500 in sequence, so as to sharpen the multiple stapler cutting knife blanks 500 in sequence, and realize the mass production of the stapler cutting knife blanks 500.

[0076] In some embodiments, before the fourth grinding wheel is used to grind a plurality of stapler cutting blade blanks in sequence to sharpen the plurality of stapler cutting blade blanks in sequence, the processing method includes: S110, causing the fourth grinding wheel to grind a preset number of stapler cutting blade blanks under different grinding conditions and grinding frequencies to sharpen the preset number of stapler cutting blade blanks.

[0077] S120, determining an optimal grinding condition and an optimal grinding frequency based on a preset number of sharpening data of stapler cutting blade blanks.

[0078] S130, based on the optimal grinding condition and the optimal grinding frequency, the fourth grinding wheel is used to grind the subsequent stapler cutting blade blank to sharpen the subsequent stapler cutting blade blank.

[0079] Among them, the processing spindle 210 can drive the fourth grinding wheel to grind a preset number of stapler cutting knife blanks 500 under different grinding conditions and grinding frequencies, so as to sharpen the preset number of stapler cutting knife blanks 500, and the preset number is, for example, 100; then, the stapler cutting knife blanks 500 after sharpening can be detected by a detection instrument such as a CCD camera taking pictures and a processor processing, and the sharpening data of the stapler cutting knife blanks 500 after sharpening, that is, the dimensional values ​​of the stapler cutting knife blanks 500 at various locations are obtained; then, the dimensional values ​​of the stapler cutting knife blanks 500 at various locations obtained after the test are compared with the dimensional values ​​of the stapler cutting knife standard parts, so as to determine the optimal grinding conditions and the optimal grinding frequency, and finally, according to the optimal grinding conditions and the optimal grinding frequency, the processing spindle 210 can drive the fourth grinding wheel to grind the subsequent stapler cutting knife blanks 500.

[0080] In some embodiments, the processing method further comprises: S140, regularly obtaining the size change information and contour change information of the stapler cutting blade blank after sharpening.

[0081] S150, adjusting the grinding frequency of the fourth grinding wheel based on the size change information and profile change information of the stapler cutting blade blank.

[0082] Among them, in order to ensure the consistency of the stapler cutting knife blank 500 after sharpening, the size change information and contour change information of the stapler cutting knife blank 500 after sharpening can be regularly obtained by, for example, taking pictures with a CCD camera and processing with a processor. For example, the size change information and contour change information of a stapler cutting knife blank 500 are obtained every 5 processing. Then, according to the size change information and contour change information of the stapler cutting knife 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 knife blank 500 after sharpening meet the standard.

[0083] In some embodiments, the processing method further comprises: S160, obtaining size change information of the fourth grinding wheel.

[0085] S180, adjusting the first grinding path based on the wear value of the fourth grinding wheel, and obtaining a third grinding path.

[0086] S190, based on the third grinding path, the fourth grinding wheel grinds the subsequent stapler cutting blade blank to sharpen the subsequent stapler cutting blade blank.

[0087] Among them, the fourth grinding wheel will be worn to a certain extent during use. After the worn fourth grinding wheel grinds the stapler cutting knife blank 500 according to the first grinding path, the size of the stapler cutting knife blank 500 will be deviated, so that the accuracy of the stapler cutting knife blank 500 after sharpening is low. In order to avoid this problem, the size change information of the fourth grinding wheel can be regularly obtained by, for example, taking pictures with a CCD camera and processing by a processor, and the wear value of the fourth grinding wheel can be determined. After that, the processor readjusts the first grinding path of the fourth grinding wheel according to the wear value of the fourth grinding wheel, thereby obtaining the third grinding path, and finally the processing spindle 210 drives the fourth grinding wheel to move along the third grinding path to grind the subsequent stapler cutting knife blank 500, thereby sharpening the subsequent stapler cutting knife blank 500.

[0088] In some embodiments, after the stapler cutting blade blank 500 is sharpened and the sharpening effect is tested to be acceptable, the stapler cutting blade blank 500 needs to be polished to make the product edge smooth and burr-free to meet the quality requirements; see Fig. 9 and Fig.10 ,Before polishing the stapler cutter, a special jig is also required, such as Fig. 9 and Fig.10 The second fixing device 300 shown in the figure includes a positioning component 311 and a covering component 312. The covering component 312 is detachably covered on the positioning component 311. A limiting space 3114 is provided between the covering component 312 and the positioning component 311.

[0089] The second fixing device 300 can be installed on the mechanical arm so that the second fixing device 300 can move relative to the polishing device. When grinding the stapler cutting blade blank 500, the stapler cutting blade blank 500 is first positioned in the limiting space 3114, and the end 510 to be ground of the stapler cutting blade blank 500 extends out of the processing exposure opening 3124; then the mechanical arm drives the second fixing device 300 to move relative to the polishing device along the grinding path, and the polishing cloth wheel of the polishing device moves to the processing exposure opening 3124 through the processing avoidance groove 3123 to grind the edge 520 to be ground of the stapler cutting blade blank 500.

[0090] The processing avoidance groove 3123 has a processing groove bottom wall 3123c, the processing groove bottom wall 3123c has a third end 3123d and a fourth end 3123e opposite to each other, the processing exposure port 3124 is arranged corresponding to the third end 3123d, and the processing groove bottom wall 3123c is arranged obliquely downward from the fourth end 3123e toward the third end 3123d.

[0091] When the polishing wheel passes through the processing avoidance groove 3123 to grind the edge 520 to be ground of the stapler cutting knife blank 500, the polishing wheel enters from the fourth end 3123e of the processing groove bottom wall 3123c and grinds the edge 520 to be ground at the processing exposure opening 3124.

By providing the limiting groove 3111a, it is convenient to store and position the stapler cutting knife blank 500. By providing the limiting groove 3111a and the cover pressing assembly 312 to enclose the limiting space 3114, when the cover pressing assembly 312 is covered on the limiting member 3111, the cover pressing assembly 312 squeezes and limits the stapler cutting knife blank 500, thereby improving the accuracy of the second fixing device 100 clamping the stapler cutting knife blank 500.

[0093] A limiting protrusion 3111b is also provided at the bottom of the limiting groove 3111a, and the limiting protrusion 3111b is used for inserting and positioning the stapler cutting knife blank 500.

[0094] The positioning assembly 311 also includes a support body 3112, which is arranged on the side of the limit member 3111 facing the covering assembly 312, and the support body 3112 has a support surface 3112a, which is arranged opposite to the processing exposure port 3124, and the support surface 3112a is used to support the part of the end 510 to be ground located at the processing exposure port 3124.

[0099] Please also see Fig.11 The portion of the cover pressing assembly 312 near the processed exposed opening 3124 includes a wear-resistant structure, and the processed exposed opening 3124 penetrates the wear-resistant structure. Since the polishing cloth wheel grinds the to-be-grinded edge 520 of the stapler cutting blade blank 500 at a high frequency, it will grind the cover pressing assembly 312 at the same time. By providing the wear-resistant structure, it is easy to withstand the high frequency grinding of the polishing cloth wheel, thereby increasing the service life of the cover pressing assembly 312.

[0100] The cover pressing assembly 312 includes a cover pressing member 3121 and a guide member 3122. The cover pressing member 3121 is detachably covered on the positioning assembly 311.

The pressing member 3133 is connected to an end of the driving shaft 3132 close to the covering and pressing assembly 312. The pressing member 3133 is used to press the covering and pressing assembly 312 against the positioning assembly 311 under the drive of the driving shaft 3132.

[0105] The positioning assembly 311 also includes a connecting seat 3113, which is arranged on the side of the limiting member 3111 away from the cover pressing assembly 312, and the connecting seat 3113 is used to connect with the robot arm. The locking driving member 3131 is arranged on the connecting seat 3113, and a through hole 3111e is provided on the limiting member 3111. A stop groove 3121c is provided on the side of the cover pressing member 3121 away from the limiting member 3111, and a waist-shaped hole 3121e is provided at the bottom of the stop groove 3121c.
