[0033] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. The drawings show the preferred embodiments of the present application.

[0034] Please refer to Figures 1 to 5 A scissor automatic sharpener 10 comprises a base 100, a sharpening assembly 200 and a material loading assembly 300. The sharpening assembly 200 comprises a sharpening driving member 210 and a grinding wheel 220. The sharpening driving member 210 is arranged on the base 100. The grinding wheel 220 is rotatably arranged on the base 100. The grinding wheel 220 is connected with an output shaft of the sharpening driving member 210. The sharpening driving member 210 is used to drive the grinding wheel 220 to rotate continuously. The material loading assembly 300 comprises a material loading driving member 310, a material loading plate 320, a positioning pin 330 and an electromagnet 340. The material loading driving member 310 is arranged on the base 100. The material loading plate 320 is arranged on the material loading driving member 310. The material loading driving member 310 is used to drive the material loading plate 320 to move close to or away from the grinding wheel 220. The positioning pin 330 and the electromagnet 340 are arranged on the material loading plate 320. The positioning pin 330 is used to pass through a blade body. The electromagnet 340 is used to adsorb and fix the blade body.

[0035] It should be noted that the sharpening driving member 210 is installed on the base 100, for example, the sharpening driving member 210 is a motor-driven speed reducer, the grinding wheel 220 is installed on the base 100 through a bearing, for example, the grinding wheel 220 is a grinding wheel, the grinding wheel 220 is connected with the output shaft of the sharpening driving member 210, and the grinding wheel 220 is driven to rotate continuously by the sharpening driving member 210. The material carrying driving member 310 is installed on the base 100, and the material carrying plate 320 is installed on the material carrying driving member 310 and is driven by the material carrying driving member 310 to approach or move away from the grinding wheel 220. The material carrying plate 320 is used to carry and fix the blade body, wherein the material carrying plate 320 is provided with a positioning pin 330 and an electromagnet 340, when the blade body is placed on the material carrying plate 320, the positioning pin 330 penetrates the blade body, and the electromagnet 340 magnetically fixes the blade body. After the blade body is fixed on the material carrying plate 320, it is driven by the material carrying driving member 310 to approach the grinding wheel 220, so that the grinding wheel 220 performs the sharpening operation on the blade body. Thus, compared with manual operation of workers, the present application can automatically sharpen the blade body of the scissors, thereby improving safety, avoiding that the scissors scratch the workers, and improving the sharpening quality of the scissors.

[0036] Please refer to Figure 3 and Figure 4 In an embodiment, the material carrying driving member 310 includes a pushing driving part 311, a bottom plate 312, a turnover driving part 313 and a rotating plate 314. The pushing driving part 311 is arranged on the base 100, the bottom plate 312 is arranged on the base 100 in a sliding manner, the bottom plate 312 is connected with the pushing driving part 311, the pushing driving part 311 is used to drive the bottom plate 312 to slide to approach or move away from the grinding wheel 220, the turnover driving part 313 is arranged on the bottom plate 312, the rotating plate 314 is arranged on the bottom plate 312 in a rotating manner, the turnover driving part 313 is connected with the rotating plate 314, and the material carrying plate 320 is arranged on the rotating plate 314.

[0037] It should be noted that the bottom plate 312 is slidingly installed on the base 100, for example, a slide rail is installed on the base 100, and the bottom plate 312 is installed on the slide rail, so that the bottom plate 312 slides on the base 100. The push top driving part 311 is installed on the base 100, and the push top driving part 311 is connected with the bottom plate 312, and the bottom plate 312 is driven to slide by the push top driving part 311. For example, the push top driving part 311 is an electric cylinder, and can also be a motor-driven lead screw module. The turnover driving part 313 is installed on the bottom plate 312, and the rotating plate 314 is installed on the bottom plate 312 through a bearing, so that the rotating plate 314 can rotate relative to the bottom plate 312. The rotating plate 314 is connected with the turnover driving part 313, so that the rotating plate 314 is driven to rotate relative to the bottom plate 312 by the turnover driving part 313. For example, the turnover driving part 313 is a pneumatic cylinder. The load plate 320 is installed on the rotating plate 314, so that the load plate 320 is driven to rotate by the turnover driving part 313, so that the tool body fixed on the load plate 320 rotates, and the grinding wheel 220 better performs the sharpening operation on the tool body.

[0038] Please refer to Figure 3 and Figure 4 In an embodiment, the load driving member 310 further comprises a load driving part 315, the load driving part 315 is arranged on the rotating plate 314, the load plate 320 is arranged on the rotating plate 314 in a rotating manner, and the load plate 320 is connected with the load driving part 315.

[0039] It should be noted that the load driving part 315 is installed on the rotating plate 314, and the load plate 320 is installed on the rotating plate 314 in a rotating manner through a bearing. The load plate 320 is driven to rotate relative to the rotating plate 314 by the load driving part 315. For example, the load driving part 315 is also a pneumatic cylinder. Thus, the rotating plate 314 is driven to rotate by the turnover driving part 313, so that the turnover driving part 313 drives the tool body to overturn by 90 degrees as a whole, which is beneficial for workers to load the tool body. Specifically, after the workers load the tool body horizontally, the tool body is driven to rotate by 90° by the turnover driving part 313, so that the cutting edge of the tool body changes from horizontal to vertical, thereby facilitating the sharpening operation of the grinding wheel 220. The load driving part 315 is arranged to drive the load plate 320 to rotate, and when the grinding wheel 220 performs the sharpening operation on the tool body, the load driving part 315 drives the tool body to rotate in a small range, so that the grinding wheel 220 better grinds the cutting edge of the tool body, thereby improving the sharpening quality.

[0040] Please refer to Figure 3 and Figure 4 In an embodiment, a plurality of anti-collision top rods 316 are arranged on the bottom plate 312, and the turnover driving part 313 is used to drive the rotating plate 314 to rotate, so that the anti-collision top rods 316 abut against the rotating plate 314.

[0041] It should be noted that the turnover driving part 313 is used to drive the rotating plate 314 to turn 90 degrees clockwise or counterclockwise. In order to avoid hard collision between the rotating plate 314 and the bottom plate 312, a collision-preventing top rod 316 is installed on the bottom plate 312, so that the collision-preventing top rod 316 is in top contact with the rotating plate 314. For example, the collision-preventing top rod 316 is a spring rubber structure.

[0042] Please refer to Figure 4 and Figure 5 In an embodiment, the material carrying assembly 300 further comprises a top holding block 350, which is arranged on the material carrying plate 320 and is used to top the blade body 20.

[0043] It should be noted that when the grinding wheel 220 grinds the cutting edge of the blade body, the blade body will be subjected to the pressure of the grinding wheel 220. In order to avoid the position deviation of the blade body, the top holding block 350 is arranged to top the blade body. The top holding block 350 is fixed on the material carrying plate 320 by bolts, so that the position of the top holding block 350 relative to the material carrying plate 320 can be adjusted.

[0044] Please refer to Figure 3 and Figure 4 In an embodiment, the material carrying driving part 310 further comprises a correction tool 317 and a correction driving part 318. The correction driving part 318 is arranged on the rotating plate 314, and the correction tool 317 is slidingly arranged on the rotating plate 314 and connected with the correction driving part 318. The correction driving part 318 is used to drive the correction tool 317 to slide, so that the correction tool 317 is aligned with or offset from the grinding wheel 220.

[0045] It should be noted that after the grinding wheel 220 is used for a period of time, the outer side wall thereof will become uneven, which will reduce the sharpening quality of the blade body. Therefore, the correction tool 317 is arranged to correct the grinding wheel 220. Specifically, the correction driving part 318 is installed on the rotating plate 314, and the correction tool 317 is installed on the correction driving part 318. The correction tool 317 is slidingly moved along the rotating plate 314 by the correction driving part 318. When the pushing and top driving part 311 drives the bottom plate 312 to slide close to the grinding wheel 220, the correction tool 317 is in contact with the grinding wheel 220. With the driving of the correction driving part 318 to slide the correction tool 317, the correction tool 317 smoothes the outer side wall of the grinding wheel 220. In an embodiment, the correction driving part 318 is a lead screw module driven by a motor. Further, the correction tool 317 is installed on the rotating plate 314 through a sliding rail, so as to ensure the stability of the correction tool 317.

[0046] Please refer to Figure 3 and Figure 4In an embodiment, the carrier driving member 310 further comprises a rotating shaft 318a, a friction wheel 318b, a friction cylinder 318c and a friction block. The rotating shaft 318a is arranged on the rotating plate 314 and is rotatably connected to the bottom plate 312. The friction wheel 318b is arranged on the rotating shaft 318a. The friction cylinder 318c is arranged on the bottom plate 312. The friction block is arranged on the output shaft of the friction cylinder 318c. The friction cylinder 318c is used to drive the friction block to abut or move away from the friction wheel 220.

[0047] It should be noted that the rotating shaft 318a is fixedly installed on the rotating plate 314 and is rotatably connected to the bottom plate 312 through a bearing, so that the rotating plate 314 can rotate relative to the bottom plate 312. The friction wheel 318b is fixedly installed on the rotating shaft 318a. The friction cylinder 318c is fixedly installed on the bottom plate 312, and the friction block is installed on the friction cylinder 318c. The friction block is driven by the friction cylinder 318c to move close to or away from the friction wheel 318b. When the friction block abuts against the friction wheel 318b, the friction force of the friction block on the friction wheel 318b is used to reliably fix the rotating plate 314 and the bottom plate 312 together. This enables the grinding wheel 220 to stably perform the sharpening operation on the cutting edge of the blade.

[0048] In an embodiment, the friction block is a plastic structure, for example, a silica gel. In this way, the friction wheel 318b can be reliably compressed.

[0049] Please refer to Figure 4 In an embodiment, the rotating plate 314 further comprises a nozzle 319 arranged towards the carrier plate 320.

[0050] It should be noted that the nozzle 319 is used to be connected to an external air compressor. The nozzle 319 is used to blow air on the cutting edge of the blade to blow away the dust generated when the grinding wheel 220 grinds the blade. This avoids the accumulation of dust on the grinding wheel 220, thereby improving the sharpening quality of the blade.

[0051] Please refer to Figure 2 In an embodiment, the base 100 further comprises a dust cover 110, and the grinding wheel 220 is located in the dust cover 110. For example, the dust cover 110 is connected to an air extractor, so that the dust generated by the grinding wheel 220 during the sharpening operation can be timely cleaned, thereby ensuring the cleanliness of the equipment.

[0052] Please refer to Figure 1 and Figure 2The automatic blade sharpening machine 10 further comprises a material preparation mechanism 400, a positioning mechanism 500 and a material moving mechanism 600. The material preparation mechanism 400 and the positioning mechanism 500 are arranged on the base 100, and the positioning mechanism 500 is located between the material preparation mechanism 400 and the material loading assembly 300. The material moving mechanism 600 is arranged on the base 100, and is used to sequentially move the blade body from the material preparation mechanism 400 to the positioning mechanism 500 and the material loading assembly 300.

[0053] Please refer to Figure 1 、 Figure 2 and Figure 6 In an embodiment, the material preparation mechanism 400 comprises a loading table 410, a horizontal moving driving member 420, a material lifting driving member 430 and a top plate 440. The horizontal moving driving member 420 is arranged on the base 100, the loading table 410 is arranged on the horizontal moving driving member 420, the material lifting driving member 430 is arranged on the base 100, and the top plate 440 is arranged on the material lifting driving member 430. The horizontal moving driving member 420 is used to drive the loading table 410 to slide close to or away from the top plate 440. When the top plate 440 is lifted by the material lifting driving member 430, the top plate 440 can lift the blade body from the loading table 410.

[0054] It should be noted that the loading table 410 is used to support a plurality of blade bodies. For example, since a pair of scissors is composed of two blade bodies, the loading table 410 is used to support the two kinds of blade bodies. The loading table 410 is installed on the horizontal moving driving member 420 and is driven by the horizontal moving driving member 420 to move horizontally. For example, the horizontal moving driving member 420 is a motor-driven belt module, and the loading table 410 is installed on the base 100 through a slide rail, so that the horizontal moving driving member 420 drives the loading table 410 to slide. When the two kinds of blade bodies of the scissors are placed on the loading table 410, the blade bodies can be driven to slide. When the loading table 410 slides close to the top plate 440 and the top plate 440 is lifted by the material lifting driving member 430, the top plate 440 can lift the blade bodies from the loading table 410. In an embodiment, the material lifting driving member 430 is a motor-driven lead screw module, and the top plate 440 is installed on the output shaft of the lead screw module, so that the top plate 440 is driven by the material lifting driving member 430 to move up and down.

[0055] Please refer to Figure 6 In an embodiment, the material preparation mechanism 400 further comprises a plurality of material boxes 450 and a plurality of pressing clamps 460. Each pressing clamp 460 is arranged on the loading table 410, and each material box 450 is placed on the loading table 410, so that each pressing clamp 460 corresponds to each material box 450 to clamp the material box 450. The material box 450 is provided with a material cavity for accommodating the blade body.

[0056] It should be noted that in order to facilitate the loading of the blade body of the scissors, a plurality of blade bodies are loaded into the magazine 450 in advance, and then the magazine 450 is installed on the loading platform 410, which facilitates the loading of the blade body. Further, the pressing clamp 460 is an elbow clamp, so that the magazine 450 can be quickly fixed.

[0057] Please refer to Figure 6 and Figure 7 In an embodiment, the loading platform 410 is provided with a positioning hole 411, and the magazine 450 is provided with a positioning protrusion 470. When the magazine 450 is placed on the loading platform 410, the positioning protrusion 470 is arranged in the positioning hole 411. In this way, by arranging the positioning protrusion 470 and the positioning hole 411 to cooperate with each other, the magazine 450 can be quickly positioned on the loading platform 410, improving the installation efficiency.

[0058] Please refer to Figure 1 and Figure 8 In an embodiment, the positioning mechanism 500 includes a positioning driving member 510, a positioning plate 520, and a sliding plate 530. The positioning driving member 510 is arranged on the base 100, and the sliding plate 530 is slidingly arranged on the base 100. One end of the positioning plate 520 is rotationally connected with the sliding plate 530, and the other end of the positioning plate 520 is rotationally connected with the output shaft of the positioning driving member 510. The positioning driving member 510 is used to push the positioning plate 520, so that the positioning plate 520 is in a horizontal state or an inclined state.

[0059] It should be noted that the positioning driving member 510 is installed on the base 100, for example, the positioning driving member 510 is a pneumatic cylinder. The sliding plate 530 is slidingly installed on the base 100 through a sliding rail, so that the sliding plate 530 can slide relative to the base 100. One end of the positioning plate 520 is rotationally connected with the sliding plate 530 through a bearing, and the other end of the positioning plate 520 is rotationally connected with the output shaft of the positioning driving member 510 through a pin shaft. In this way, the positioning plate 520 is pushed by the positioning driving member 510, so that the positioning plate 520 can be in a horizontal state or an inclined state. It should be noted that the blade body is placed in a horizontal state in the magazine 450, but it needs to be in an inclined state in the loading assembly 300, so that the cutting edge of the blade body is in a horizontal state, which facilitates the sharpening operation. Therefore, the positioning mechanism 500 is arranged to change the state of the blade body.

[0060] In an embodiment, the positioning plate 520 and the sliding plate 530 are both provided with two, and a spacing is arranged between the two sliding plates 530. One end of the two positioning plates 520 is respectively rotationally connected with the two sliding plates 530, and the other end of the two positioning plates 520 is rotationally connected with the output shaft of the positioning driving member 510. In this way, the state of the two positioning plates 520 is changed by the positioning driving member 510 at the same time, so that the state of the two blade bodies of one pair of scissors is changed at the same time, thereby improving the loading efficiency of the scissors.

[0061] Referring to Figure 8 In an embodiment, the positioning mechanism 500 further comprises a positioning column 540, a pressing cylinder 550, a pressing wheel 560 and a pressing column 570. The positioning column 540 is arranged on the positioning plate 520. The pressing wheel 560 is rotatably arranged on the positioning plate 520. The pressing cylinder 550 is arranged on the positioning plate 520. The pressing column 570 is arranged on an output shaft of the pressing cylinder 550, and the pressing column 570 is aligned with the pressing wheel 560.

[0062] It should be noted that when the blade is placed on the positioning plate 520, in order to ensure that the blade is placed correctly, the positioning column 540 is arranged to pass through the blade to align it. At the same time, the pressing cylinder 550 is arranged to drive the pressing column 570 to approach the pressing wheel 560, so that the pressing column 570 and the pressing wheel 560 jointly clamp the blade, thereby adjusting the position of the blade.

[0063] Referring to Figure 1 and Figure 9 In an embodiment, the material moving mechanism 600 comprises a material moving drive 610, a first material taking member 620 and a second material taking member 630. The material moving drive 610 is arranged on the base 100. The first material taking member 620 and the second material taking member 630 are both slidably arranged on the base 100, and are both connected with the material moving drive 610. The material moving drive 610 is used to drive the first material taking member 620 to reciprocate between the material preparation mechanism 400 and the positioning mechanism 500, while driving the second material taking member 630 to reciprocate between the positioning mechanism 500 and the material carrying assembly 300.

[0064] It should be noted that the material moving drive 610 is used to drive the first material taking member 620 and the second material taking member 630 to move synchronously, so that the first material taking member 620 moves the blade from the material preparation mechanism 400 to the positioning mechanism 500 for position adjustment, and so that the second material taking member 630 moves the blade from the positioning mechanism 500 to the material carrying assembly 300 for sharpening. In an embodiment, the material moving drive 610 is a lead screw module driven by a motor. The first material taking member 620 and the second material taking member 630 are both mounted on the base 100 through a slide rail.

[0065] Referring to Figure 9In an embodiment, the first material taking member 620 comprises a first material taking cylinder 621, a first material taking block 622, a material taking spring 623, a first material releasing cylinder 624, a first material taking magnet 625 and a first material taking plate 626. The first material taking cylinder 621 is connected with the output shaft of the material moving driving member 610. The first material taking plate 626 is arranged on the output shaft of the first material taking cylinder 621. The first material taking block 622 is slidingly arranged on the first material taking plate 626. The material taking spring 623 is in abutment with the first material taking block 622 and the first material taking plate 626 respectively. The first material releasing cylinder 624 is arranged on the first material taking block 622. The first material taking magnet 625 is arranged on the first material taking block 622.

[0066] It should be noted that the first material taking member 620 is used to move the blade body from the material preparation mechanism 400 to the positioning mechanism 500. Specifically, the first material taking cylinder 621 drives the first material taking plate 626 to descend, so that the first material taking magnet 625 is in abutment with and is attracted to the blade body. When the first material taking block 622 is in contact with the blade body, the material taking spring 623 is compressed under force, thus having a buffering capacity, avoiding hard contact between the first material taking magnet 625 and the blade body. When the blade body is released, the first material releasing cylinder 624 pushes the blade body, so that the blade body is separated from the first material taking magnet 625 to achieve material releasing. For example, the first material taking magnet 625 is an electromagnet structure.

[0067] Please refer to Figure 9 In an embodiment, the second material taking member 630 comprises a second material taking cylinder 631, a second material taking plate 632, a second rotating block 633, a second lifting block 634, a second magnet 635 and a second material releasing cylinder 636. The second material taking cylinder 631 is connected with the output shaft of the material moving driving member 610. The second material taking plate 632 is arranged on the output shaft of the second material taking cylinder 631. The second lifting block 634 is slidingly arranged on the second material taking plate 632. One end of the second rotating block 633 is rotatably arranged on the second material taking plate 632. The other end of the second rotating block 633 is rotatably connected with the second lifting block 634. The second lifting block 634 is used to drive the second rotating block 633 to rotate. The second magnet 635 and the second material releasing cylinder 636 are arranged on the second rotating block 633.

[0068] It should be noted that the knife body is in a horizontal state in the preparation mechanism 400, and the knife body is in an inclined state in the loading assembly 300, and therefore the positioning mechanism 500 is used to transform the knife body from the horizontal state to the inclined state. Therefore, the second material taking member 630 is used to take and place the knife body in the inclined state. Therefore, the inclination angle of the second rotating block 633 is adjusted by the second lifting block 634, and since the second magnet 635 and the second stripping cylinder 636 are both mounted on the second rotating block 633, the inclination angle of the second magnet 635 and the second stripping cylinder 636 can be adjusted. The second magnet 635 is an electromagnet structure, which is used to adsorb and fix the knife body, and the second stripping cylinder 636 is used to push the knife body to separate the knife body from the second magnet 635, so as to achieve the placing of the material.

[0069] Further, please refer to Figure 1 、 Figure 2 and Figure 10 In an embodiment, the automatic knife sharpener 10 further comprises an assembling mechanism 700, which is arranged adjacent to the loading assembly 300. The assembling mechanism 700 comprises a loading plate 710 and an assembling driving member 720, which is arranged on the base 100. The loading plate 710 is arranged on the output shaft of the assembling driving member 720, and the assembling driving member 720 is used to drive the loading plate 710 to perform lifting movement. The loading plate 710 is provided with a loading column 730 and two loading blocks 740, and the loading column 730 and the two loading blocks 740 are arranged on the loading plate 710. One of the two loading blocks 740 and the loading column 730 are used to jointly support one of the two knife bodies, and the other loading block 740 and the loading column 730 are used to jointly support the other knife body.

[0070] It should be noted that after the two knife bodies of the scissors are sharpened by the cooperation of the sharpening assembly 200 and the loading assembly 300, the two knife bodies are moved to the assembling mechanism 700 by the material moving mechanism 600 for assembly, and the loading column 730 passes through the perforations of the two knife bodies for positioning. In an embodiment, a slot for limiting the end of the knife body is formed in the loading block 740.

[0071] Please refer to Figure 9 In an embodiment, the material moving mechanism 600 further comprises a third material taking member 640, which is slidingly arranged on the base 100 and connected with the material moving driving member 610. The material moving driving member 610 is used to drive the third material taking member 640 to perform reciprocating movement between the loading assembly 300 and the assembling mechanism 700, so that the third material taking member 640 moves the two knife bodies after sharpening from the loading assembly 300 to the assembling mechanism 700.

[0072] Further, please refer to Figure 9The third taking member 640 comprises a third taking cylinder 641, a third taking plate 642, a third rotating block 643, a third lifting block 644, a third lifting cylinder 645, a third rotating cylinder 645 and a third magnet 646.

The third rotating block 643 is rotatably arranged on the third taking plate 642. The third lifting block 644 is slidably arranged on the third taking plate 642. The third lifting cylinder 645 is arranged on the third taking plate 642, and the output shaft of the third lifting cylinder 645 is connected with the third lifting block 644. The third rotating cylinder 645 is arranged on the third rotating block 643. The third magnet 646 is arranged on the output shaft of the third rotating cylinder 645.

[0073] It should be noted that, since the blade is in an inclined state when carried by the material carrying assembly 300 for sharpening, and the blade is in a horizontal state in the assembling mechanism 700, and the blade needs to be rotated by 90 degrees in the horizontal direction. Specifically, the third taking cylinder 641 drives the third taking plate 642 to perform lifting movement, the third lifting cylinder 645 drives the third lifting block 644 to perform lifting movement, so that the third rotating block 643 can rotate to change into a horizontal state or an inclined state, and the third rotating cylinder 645 is used to drive the third magnet 646 to rotate along the horizontal direction, so that the adsorbed blade can be rotated by 90 degrees along the horizontal direction. In this way, the third taking member 640 moves the scissors after sharpening to the assembling mechanism 700 to be assembled into a structure of being hingedly connected.

[0074] Please refer to Figure 1 , Figure 2 and Figure 10 In an embodiment, the automatic scissors sharpening machine 10 further comprises a material feeding mechanism 800. The material feeding mechanism 800 comprises a material feeding driving member 810, a material feeding clamp 820 and a material feeding belt 830. The material feeding driving member 810 is arranged on the base 100. The material feeding belt 830 is rotatably arranged on the base 100. The material feeding clamp 820 is arranged on the material feeding driving member 810. The material feeding driving member 810 is used to drive the material feeding clamp 820 to perform reciprocating movement between the material feeding belt 830 and the assembling mechanism 700, so that the material feeding clamp 820 moves the scissors from the assembling mechanism 700 to the material feeding belt 830.

[0075] Please refer to Figure 10In an embodiment, the discharging driving member 810 comprises a transverse movement module 811 and a discharging cylinder 812. The transverse movement module 811 is arranged on the base 100, and the discharging cylinder 812 is arranged on the transverse movement module 811. The transverse movement module 811 is used to drive the discharging cylinder 812 to reciprocate between the discharging belt 830 and the assembling mechanism 700. The discharging clamp 820 is arranged on the output shaft of the discharging cylinder 812, and the discharging cylinder 812 is used to drive the discharging clamp 820 to move up and down. For example, the transverse movement module 811 is a belt module driven by a motor. The discharging cylinder 812 is slidingly arranged on the base 100 and is driven by the transverse movement module 811 to move transversely.

[0076] Please refer to Figure 1 、 Figure 2 and Figure 11 In an embodiment, the discharging mechanism 800 further comprises a rotating belt 840, a rotating module 850 and a plurality of rotating jigs 860.

In order to automatically transfer the scissors to the riveting machine for riveting operation, the discharging belt 830 is arranged to transfer the scissors. The discharging belt 830 is used to convey the rotating jig 860. For example, the rotating jig 860 is provided with a material groove for limiting the scissors. Further, the rotating module 850 is connected with the rotating belt 840 and the discharging belt 830 respectively. After the empty rotating jig 860 enters the rotating belt 840, it is transferred to the discharging belt 830 by the rotating module 850. Then, the discharging clamp 820 driven by the discharging driving member 810 transfers the scissors to the rotating jig 860. The rotating jig 860 carrying the scissors is then moved out of the discharging belt 830 and enters the next riveting process. In this way, the production automation level is improved, thereby improving the production efficiency of the scissors.

[0078] In an embodiment, the discharging belt 830 and the rotating belt 840 are both belts driven by a motor through bearings. After the rotating jig 860 is placed on the belt, the rotating jig 860 can be moved. Further, in an embodiment, the rotating module 850 is a screw module driven by a motor.
