Description

Technical Field

[0001] The invention belongs to the technical field of micro-drill sorting equipment, in particular to an automatic handle sorting equipment and method. Background Art

[0002] Micro drills usually refer to drills with a diameter less than 3.175mm. They are generally made of 100% pure carbide. The hardness of this alloy is 3 times higher than that of hard steel, which makes the micro drills have higher hardness, precision, rigidity, wear resistance, corrosion resistance and other excellent properties. After the micro drills are processed and formed, many non-standard workpieces will appear. When recycling these workpieces, it is necessary to measure their shank diameters and then recycle them according to the size of the shank diameters. The micro drills with small shank diameters are processed into other workpieces, and the micro drills with large shank diameters are modified to make micro drills with small shank diameters. This process requires the use of micro drill shank measurement and sorting equipment.

[0003] After searching, CN216369019U discloses an automatic measuring machine for net handle length, including a machine base, a mounting plate is arranged on the machine base, a feeding mechanism and a dividing mechanism connected to the feeding mechanism are arranged on the mounting plate, a measuring mechanism is arranged on the mounting plate on the side of the dividing mechanism, a receiving mechanism is arranged on the machine base at the lower side of the dividing mechanism, the receiving mechanism includes a micro-drill feeding rod arranged on one side of the dividing mechanism, and a base arranged on the other side of the dividing mechanism, a conveyor belt is arranged on the base, the conveyor belt is driven along the pushing direction of the micro-drill feeding rod, a plurality of receiving boxes are arranged on one side of the conveyor belt, a V-shaped feeding frame is arranged on the end of the receiving box close to the conveyor belt, a telescopic cylinder corresponding to the receiving box is arranged on the other side of the conveyor belt, and a feeding block is arranged on the end of the telescopic cylinder close to the conveyor belt.

[0004] However, since the existing automated measuring handle sorting equipment lacks the function of automatic loading after unloading, this results in that after the workpieces have undergone a precise sorting process and are accurately sent to a receiving container of corresponding size or length, they still need to rely on manual operation to complete the subsequent transfer steps. During this process, the operator must directly reach into the receiving box, take out the workpiece by manual grabbing, and then place it in a designated placement box or storage area. This process not only greatly increases the labor intensity of the operator, but also has certain safety hazards. Since the workpieces have sharp tips, direct manual contact can easily cause scratches or punctures. In addition, after the workpieces are sorted, since there is no automatic receiving and packaging mechanism, the workpieces can only be stacked in the receiving box at will, which makes the surface of the workpiece very easy to be scratched, deformed or even broken due to mutual squeezing and collision between the workpieces.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 13 As shown, an automatic handle measuring and sorting device described in an embodiment of the present invention comprises a workbench 1, a length detection seat 2 is fixedly installed on the workbench 1, an automatic material discharge hopper 3 is fixedly connected to the top of the length detection seat 2, a slidable manipulator 4 is arranged on one side of the length detection seat 2, a material guide seat 5 is arranged below the manipulator 4, the material guide seat 5 is fixedly connected to the top of the workbench 1, a material receiving box 10 is evenly arranged on one side of the material guide seat 5, the material receiving box 10 is fixedly connected to the workbench 1, a conveyor belt 11 is installed in the material receiving box 10, material blocks 13 are evenly fixedly connected to the conveyor belt 11, and the material blocks 13 are grouped in pairs and are symmetrically distributed, a material pushing mechanism is arranged on the side of the material receiving box 10 away from the material guide seat 5, bosses 23 are evenly fixedly connected to the top of the workbench 1, the bosses 23 are staggered with the material receiving box 10, and a placement box 26 is arranged on the bosses 23; The workpieces are then fed to the material collecting box 10 and the conveyor belt 11 is moved to the loading platform 21 for loading. The probability of the sharp end of the workpiece stabbing the staff is reduced, and the problem of the existing automatic measuring handle sorting equipment lacking the function of automatic loading after unloading is effectively solved. This results in that after the workpiece has passed the precise sorting process and is accurately sent to the receiving container of the corresponding size or length, it still needs to rely on manual operation to complete the subsequent transfer steps. In this process, the operator must directly reach into the receiving box 10, take out the workpiece by manual grasping, and then place it in the designated placement box 26 or storage area. This process not only greatly increases the labor intensity of the operator, but also has certain safety hazards. Since the workpiece has a sharp tip, direct manual contact can easily cause scratches or punctures. In addition, after the workpiece is sorted, since there is no automatic receiving and packaging mechanism, the workpiece can only be randomly stacked in the receiving box 10, which makes the surface of the workpiece very easy to be scratched, deformed or even broken due to mutual squeezing and collision between the workpieces.

[0023] like Figure 2 and Figure 4 As shown, the top of the material guide seat 5 is in an inverted V-shaped opening, and the material guide slots 6 are evenly opened on the material guide seat 5. The material guide slots 6 are connected to the inverted V-shaped opening of the material guide seat 5. A slidable limit block 9 is arranged in the material guide slot 6. A cylinder 8 is evenly fixedly installed on the side of the material guide seat 5 away from the material receiving box 10. The output end of the cylinder 8 is fixedly connected to the limit block 9. A through groove is arranged in the center of the limit block 9. A baffle 7 is fixedly connected to the side of the material guide seat 5 away from the cylinder 8. The baffle 7 is adapted to the conveyor belt 11. A delay sensor 12 is fixedly installed on the inner wall of the material receiving box 10, and the limit block 9 is adapted to the delay sensor 12. In this embodiment, the top of the material guide seat 5 is designed to be an inverted V-shaped opening and connected to a plurality of material guide grooves 6, so that the manipulator 4 can put the workpiece into the corresponding material guide groove 6 after clamping it. Since the limiting block 9 is set in the material guide groove 6 in the initial state, the workpiece will automatically fall into the through groove of the limiting block 9 after entering the material guide groove 6. At this time, the cylinder 8 is started, and the limiting block 9 is driven by the cylinder 8 to leave the material guide groove 6 and slide to the top of the baffle 7, so that the workpiece slides therewith until the limiting block 9 is separated from the baffle 7, and the workpiece falls from the limiting block 9 into a group of corresponding Between the card blocks 13, the cylinder 8 drives the limit block 9 to reset. During this process, when the workpiece falls from the limit block 9, the delay sensor 12 on the receiving box 10 senses the limit block 9, and controls the conveyor belt 11 to start transmission after the workpiece falls between a group of card blocks 13, so that a group of empty card blocks 13 are transmitted to the bottom of the baffle 7, so that the next limit block 9 can correspondingly unload the material. Through this structure, the sorted workpieces can be placed one by one between the card blocks 13 on the conveyor belt 11 to avoid collision and extrusion between each other.

[0024] like Figure 3 and Figure 6 As shown, the pushing mechanism includes a bracket 14, a second cylinder 15 and a push plate 22. The bracket 14 is fixedly connected to the side of the receiving box 10 away from the material guide seat 5. The second cylinder 15 is fixedly installed on the side wall of the bracket 14. The output end of the second cylinder 15 is fixedly connected to the mounting frame 16. The mounting frame 16 is slidably connected to the side wall of the bracket 14. A motor 18 is fixedly connected to the mounting frame 16. The output end of the motor 18 is fixedly connected to a screw rod 19. The screw rod 19 is rotatably connected to the mounting frame 16. A threaded sleeve 20 is threadedly connected to the screw rod 19. A slide groove 17 is provided on the top of the mounting frame 16. The threaded sleeve 20 is slidably connected to the slide groove 17. The bottom end of the threaded sleeve 20 is fixedly connected to a mounting plate 21. The bottom end of the mounting plate 21 is evenly fixedly connected to a push plate 22. The push plate 22 is adapted to the clamping block 13. In this embodiment, when the conveyor belt 11 transfers the workpiece to the bottom of the push plate 22, the cylinder 15 is started, and the mounting frame 16 is driven to move downward as a whole by the cylinder 15, so that the push plate 22 slides down to one side of the workpiece. At this time, the motor 18 rotates forward and drives the screw rod 19 to rotate, so that the screw sleeve 20 drives the mounting plate 21 to move, and then the multiple push plates 22 move accordingly, and push a number of workpieces into the placement box 26 on the boss 23, thereby realizing automatic transfer after the workpiece is unloaded.

[0025] like Figure 2-Figure 3 and Figure 5 As shown, the top of the boss 23 is symmetrically provided with a second slide groove 24, the four corners of the bottom of the placement box 26 are fixed with sliders 27, the sliders 27 are slidably connected with the second slide groove 24, the top of the placement box 26 is evenly provided with placement grooves 29, the placement grooves 29 are arc-shaped, and the four corners of the top of the placement box 26 are provided with card slots 28, and the card slots 28 are adapted to the sliders 27; In this embodiment, the sliding cooperation between the slide groove 24 on the top of the boss 23 and the slider 27 at the bottom of the placement box 26 makes it convenient for the staff to slide the placement box 26 on the boss 23. The slot 28 designed on the top of the placement box 26 makes it convenient for the staff to stack the filled placement boxes 26. The multiple arc-shaped placement grooves 29 designed in the placement box 26 facilitate the stable storage of the workpiece, and the bottom of the placement groove 29 and the workpiece can be designed to be made of rubber material to further reduce the wear on the workpiece.

[0026] like Figure 3 and Figure 5 As shown, a notch is provided on one side of the material receiving box 10 away from the material guiding seat 5, and a material guiding plate 25 is evenly fixedly connected to the notch of the material receiving box 10, and the material guiding plate 25 is arc-shaped, and a fixed sleeve 30 is inlaid below the notch of the material receiving box 10, and a stopper 32 is slidably connected in the inner cavity of the fixed sleeve 30, and a spring 31 is fixedly connected between the stopper 32 and the inner cavity of the fixed sleeve 30, and one end of the stopper 32 away from the spring 31 extends to the outside of the fixed sleeve 30 and is adapted to the placement box 26, and one end of the stopper 32 away from the spring 31 is provided with an inclined surface; In this embodiment, an arc-shaped material guide plate 25 is provided at the notch of the receiving box 10, so that the push plate 22 can stably push the workpiece into the corresponding placement box 26. By providing a stopper 32, when the staff slides the placement box 26 on the boss 23, the placement box 26 can be easily slid to the corresponding position to facilitate the unloading of the push plate 22. When the placement box 26 filled with workpieces needs to be slid away for stacking, the inclined surface designed on the stopper 32 makes it convenient for the staff to squeeze the stopper 32 when sliding the placement box 26, so that it shrinks away from the placement box 26 and compresses the spring 31 in the fixed sleeve 30 until the placement box 26 slides away from the stopper 32. The stopper 32 can be quickly reset under the elastic force of the spring 31 to position the next empty placement box 26.

[0027] like Figure 4 and Figure 7 As shown, the cross section of the material blocks 13 is trapezoidal, and the opposite sides of each group of material blocks 13 are inclined surfaces, and the opposite sides of each group of material blocks 13 are fixedly connected to the sponge rollers 33; In this embodiment, by designing the opposite sides of each group of clamping blocks 13 to be inclined surfaces, it is convenient to guide and place the workpiece when it falls. By arranging a sponge roller 33 on the clamping blocks 13, the impact and collision generated when the workpiece falls can be reduced, thereby avoiding wear of the workpiece.

[0028] like Figure 2-Figure 4 as well as Figure 7-Figure 13As shown, a rack 1 34 and a contact switch 2 40 are fixedly connected to the inner wall of the material receiving box 10 on one side close to the material guiding seat 5, and the contact switch 2 40 is located above the rack 1 34. A rack 2 35 is provided on the side of the rack 1 34 away from the material guiding seat 5. The rack 2 35 is fixedly connected to the inner wall of the material receiving box 10. A mounting sleeve 36 is provided between each group of material blocks 13. An L-shaped connecting plate 37 is fixedly connected to the outer wall of the mounting sleeve 36. The L-shaped connecting plate 37 is fixedly connected to the end of one of the material blocks 13. An annular groove 1 42, a spiral groove 44 and an annular groove 2 43 are sequentially provided on the inner wall of the mounting sleeve 36. The two ends of the spiral groove 44 are respectively connected to the annular groove 1 42 and the annular groove 2 43. A rotating shaft 38 is rotatably connected to the mounting sleeve 36, and one end of the rotating shaft 38 extends A contact switch 1 39 is fixedly connected to the outer side of the mounting sleeve 36, and the contact switch 1 39 is matched with the contact switch 2 40. A gear 41 is fixedly connected to the side of the rotating shaft 38 close to the contact switch 1 39, and the gear 41 is meshedly connected with the rack 1 34 and the rack 2 35. A mounting ring 46 is provided in the inner cavity of the mounting sleeve 36, and a limiting groove 47 is provided on the inner wall of the mounting ring 46. A limiting protrusion 45 is fixedly connected to the rotating shaft 38, and the limiting protrusion 45 is slidably connected with the limiting groove 47. A guide component is provided on the mounting ring 46, and the guide component is matched with the annular groove 1 42, the annular groove 2 43 and the spiral groove 44. A plurality of support arms 51 are fixedly connected to the side of the mounting ring 46 away from the gear 41, and one end of the support arm 51 extends to the outer side of the mounting sleeve 36 and is provided with a clamping component. In this embodiment, when the conveyor belt 11 drives the workpiece on the clamping block 13 to move toward one side of the pushing mechanism, the gear 41 on the mounting sleeve 36 fixed to the clamping block 13 first meshes with the rack 1 34. At this time, the contact switch 1 39 and the contact switch 2 40 are not in contact. Since the teeth of the rack 1 34 are designed to be upward, the gear 41 drives the rotating shaft 38 to rotate forward after meshing with the rack 1 34, so that the guide assembly on the mounting ring 46 slides from the annular groove 1 42 through the spiral groove 44 into the annular groove 2 43 and remains in the annular groove 2 43. During this process, the mounting ring 46 slides along the rotating shaft 38 toward the side away from the gear 41 under the drive of the guide assembly, so that the clamping assembly on the support arm 51 corresponds to the end of the workpiece, until the contact switch 1 39 and the contact switch 2 40 are in contact, and the clamping assembly is started to fix the end of the workpiece. Later, when the mounting ring 46 continues to rotate with the gear 41 on the rotating shaft 38, the support arm 51 drives the workpiece to rotate together through the clamping assembly, so that the workpiece rubs against the sponge roller 33. The sponge roller 33 can wipe the surface of the workpiece before boxing, so that the workpiece can be in a clean state after boxing, avoiding the tedious process of manual wiping of the surface of the workpiece by the staff when the workpiece is subjected to subsequent processes. When the contact switch 2 40 is disengaged from the contact switch 1 39, the clamping assembly releases the workpiece. Thereafter, the gear 41 first disengages from the rack 1 34 and then meshes with the rack 2 35. Because the teeth of the rack 2 35 are downward, the gear 41 drives the rotating shaft 38 to reverse, thereby causing the guide assembly to slide from the annular groove 2 43 through the spiral groove 44 and then back into the annular groove 1 42. The support arm 51 then drives the clamping assembly away from the workpiece, facilitating the subsequent pushing mechanism to transfer the workpiece.

[0029] like Figure 7-Figure 13 As shown, the guide assembly includes a guide sleeve 48 and a guide block 50. The guide sleeve 48 is movably connected to the side wall of the mounting ring 46. The guide block 50 is slidably connected in the inner cavity of the guide sleeve 48. An elastic gasket 49 is fixedly connected between the guide block 50 and the inner wall of the guide sleeve 48. One end of the guide block 50 away from the elastic gasket 49 extends to the outside of the guide sleeve 48. The guide block 50 is slidably connected to the annular groove 1 42, the annular groove 2 43 and the spiral groove 44. A gasket 1 58 is fixedly connected in the annular groove 1 42. The gasket 1 58 is located at the connection between the annular groove 1 42 and the spiral groove 44, and one end of the gasket 1 58 is provided with an inclined surface. A gasket 2 59 is fixedly connected in the annular groove 2 43. The gasket 2 59 is located at the connection between the annular groove 2 43 and the spiral groove 44, and one end of the gasket 2 59 is provided with an inclined surface. In this embodiment, when the gear 41 is meshed with the rack 1 34, the guide block 50 is blocked by the pad 1 58 and directly slides into the spiral groove 44, and slides from the spiral groove 44 into the annular groove 2 43, and then slides in a circular manner in the annular groove 2 43 and continuously contacts with the pad 2 59. When passing the inclined surface of the pad 2 59, the guide block 50 slides into the guide sleeve 48 and compresses the elastic gasket 49 until the guide block 50 is separated from the pad 2 59. Under the elastic force of the elastic gasket 49, the guide block 50 is again fitted with the annular groove 2 43 until the gear 41 is separated from the rack 1 34 and meshed with the rack 2 35. The guide block 50 reverses in the annular groove 2 43, and after being blocked by the pad 2 59, it directly slides into the spiral groove 44, and then returns from the spiral groove 44 to the annular groove 1 42. Thereafter, the guide block 50 slides in a circular manner in the annular groove 1 42 and continuously contacts with the pad 1 58.

[0030] like Figure 7-Figure 11 As shown, the clamping assembly includes a second fixed sleeve 52, an electromagnet 53 and an arc-shaped clamping plate 57. The second fixed sleeve 52 is fixedly connected to the side wall of the end of the support arm 51 away from the mounting ring 46, and the electromagnet 53 is fixedly connected in the second fixed sleeve 52. A permanent magnet 54 is slidably connected in the inner cavity of the second fixed sleeve 52. A second spring 56 is fixedly connected between the permanent magnet 54 and the inner cavity of the second fixed sleeve 52. A support rod 55 is fixedly connected to the side of the permanent magnet 54 away from the electromagnet 53. One end of the support rod 55 away from the permanent magnet 54 extends to the outside of the second fixed sleeve 52 and is fixedly connected to the arc-shaped clamping plate 57. The arc-shaped clamping plate 57 is slidably connected to the support arm 51. In this embodiment, when contact switch 1 39 and contact switch 2 40 are in contact, the electromagnet 53 is energized to generate suction, so that the permanent magnet 54 drives the support rod 55 to slide into the fixed sleeve 2 52 while stretching the spring 2 56, and the arc-shaped clamping plate 57 slides accordingly and clamps the end of the workpiece. When contact switch 1 39 and contact switch 2 40 are disengaged, the electromagnet 53 is de-energized, and the permanent magnet 54 is reset under the pulling force of the spring 2 56, and the arc-shaped clamping plate 57 moves away from the workpiece.

[0031] A method for automatically measuring handle sorting equipment, the method is applicable to the above-mentioned automatic measuring handle sorting equipment, the method comprises the following steps: S1: The staff puts the workpiece into the automatic unloading hopper 3, so that the workpieces enter the length detection station 2 one by one along the automatic unloading hopper 3, and the length of the workpiece can be detected by the length detection station 2; S2: After being detected by the length detection station 2, the workpieces of different lengths are placed into the material guide station 5 by the manipulator 4. After being discharged from the material guide station 5, the workpieces of different lengths enter into different receiving boxes 10 accordingly, and are placed one by one between the clamping blocks 13 on the conveyor belt 11; S3: The workpieces are transferred to the pushing mechanism via the conveyor belt 11 , and then the pushing mechanism pushes the workpieces transferred to the other side of the conveyor belt 11 into the placement box 26 on the boss 23 . Finally, the staff removes the filled placement box 26 from the boss 23 .

[0032] Working principle: the staff puts the workpiece into the automatic unloading hopper 3, so that the workpiece enters the length detection station 2 one by one along the automatic unloading hopper 3. After being detected by the length detection station 2, the manipulator 4 puts the workpieces of different lengths into the guide seat 5. After being discharged from the guide seat 5, the workpieces of different lengths enter into different receiving boxes 10 accordingly, and are placed one by one between the card blocks 13 on the conveyor belt 11, and are transferred to the pushing mechanism through the conveyor belt 11. Then, the pushing mechanism pushes several workpieces transferred to the other side of the conveyor belt 11 into the placement box 26 on the boss 23. Finally, the staff removes the filled placement box 26 from the boss 23. Through this structure, the workpiece can enter different corresponding boxes from the guide seat 5 after the length is detected. The workpiece is automatically and neatly placed in the receiving box 10 through the cooperation of the conveyor belt 11 and the pushing mechanism, thereby avoiding the process of workers grabbing the workpiece by hand and reducing the probability of the sharp end of the workpiece stabbing the workers. By designing the top of the guide seat 5 to be an inverted V-shaped opening and connected with multiple guide grooves 6, the manipulator 4 can put the workpiece into the corresponding guide groove 6 after clamping it. Since a limiting block 9 is provided in the guide groove 6 in the initial state, the workpiece will automatically fall into the through groove of the limiting block 9 after entering the guide groove 6. At this time, the cylinder 8 is started, and the limiting block 9 is driven by the cylinder 8 to leave the guide groove 6 and slide to the top of the baffle 7, so that the workpiece slides therewith until the limiting block 9 is separated from the baffle 7 and the workpiece falls from the limiting block 9. When the workpiece falls between a group of corresponding card blocks 13, the cylinder 1 8 drives the limit block 9 to reset. During this process, when the workpiece falls from the limit block 9, the delay sensor 12 on the receiving box 10 senses the limit block 9, and controls the conveyor belt 11 to start transmission after the workpiece falls between a group of card blocks 13, so that a group of empty card blocks 13 are transmitted to the bottom of the baffle 7, so that the limit block 9 can correspondingly unload the material next time. When the conveyor belt 11 transfers the workpiece to the bottom of the push plate 22, the cylinder 2 15 is started, and the mounting frame 16 is driven to move downward as a whole through the cylinder 2 15, so that the push plate 22 slides down to one side of the workpiece. At this time, the motor 18 rotates forward and drives the screw rod 19 to rotate, so that the wire sleeve 20 drives the mounting plate 21 to move, and then the multiple push plates 22 move accordingly, and A number of workpieces are pushed into the placement box 26 on the boss 23, realizing automatic transfer of the workpieces after unloading. The sliding cooperation between the slide groove 24 on the top of the boss 23 and the slider 27 at the bottom of the placement box 26 facilitates the staff to slide the placement box 26 on the boss 23. The slot 28 designed on the top of the placement box 26 facilitates the staff to stack the filled placement boxes 26. The multiple arc-shaped placement grooves 29 designed in the placement box 26 facilitate stable storage of the workpieces, and the bottom of the placement groove 29 and the workpiece can be designed to be made of rubber material to further reduce the wear on the workpiece. The arc-shaped guide plate 25 is provided at the notch of the receiving box 10, so that the push plate 22 can stably push the workpiece into the corresponding placement box 26.By setting the stopper 32, when the worker slides the placement box 26 on the boss 23, the placement box 26 can be easily slid to the corresponding position to facilitate the unloading of the push plate 22. When the placement box 26 filled with workpieces needs to be slid away for stacking, the inclined surface designed on the stopper 32 makes it easy for the worker to squeeze the stopper 32 when sliding the placement box 26, so that it shrinks away from the placement box 26 and compresses the spring 31 in the fixed sleeve 30 until the placement box 26 slides off the stopper 32. The stopper 32 can be quickly reset under the elastic force of the spring 31 to position the next empty placement box 26. By designing the opposite sides of each group of card blocks 13 to have inclined surfaces, it is convenient for the guided placement of the workpiece when it falls. The sponge roller 33 is provided to reduce the impact and collision generated when the workpiece falls, and avoid the wear of the workpiece. When the conveyor belt 11 drives the workpiece on the card block 13 to move toward the side of the pushing mechanism, the gear 41 on the mounting sleeve 36 fixed to the card block 13 first meshes with the rack 1 34. At this time, the contact switch 1 39 and the contact switch 2 40 are not in contact. Since the teeth of the rack 1 34 are designed to be upward, the gear 41 drives the rotating shaft 38 to rotate forward after meshing with the rack 1 34, so that the guide component on the mounting ring 46 slides from the annular groove 1 42 through the spiral groove 44 into the annular groove 2 43 and remains in the annular groove 2 43. In this process, the mounting ring 46 is driven by the guide component along the rotating shaft 38 to move away from the gear 4 1, so that the clamping assembly on the support arm 51 corresponds to the end of the workpiece, until the contact switch 1 39 and the contact switch 2 40 are fitted, the clamping assembly is started to fix the end of the workpiece, and thereafter, when the mounting ring 46 continues to rotate with the gear 41 on the rotating shaft 38, the support arm 51 drives the workpiece to rotate together through the clamping assembly, so that the workpiece rubs against the sponge roller 33, and the sponge roller 33 can be used to wipe the surface of the workpiece before boxing, so that the surface of the workpiece can be in a clean state after boxing, avoiding the tedious process of manually wiping the surface of the workpiece when the workpiece is subjected to subsequent processes. When the contact switch 2 40 is disengaged from the contact switch 1 39, the clamping assembly releases the workpiece, and thereafter, the gear 41 first disengages from the rack 1 34 Then it meshes with rack 2 35, and because the teeth of rack 2 35 are facing downward, gear 41 drives rotating shaft 38 to reverse, so that the guide assembly slides from annular groove 2 43 through spiral groove 44 and then back into annular groove 1 42, and support arm 51 drives clamping assembly away from workpiece, so as to facilitate subsequent pushing mechanism to transfer workpiece. When gear 41 meshes with rack 1 34, guide block 50 is blocked by pad 1 58 and slides directly into spiral groove 44, and then slides from spiral groove 44 into annular groove 2 43, and then slides in annular groove 2 43 in a cycle in annular groove 2 43 and continuously contacts pad 2 59. When passing the inclined surface of pad 2 59, guide block 50 slides into guide sleeve 48 and compresses elastic gasket 49 until guide block 50 is separated from pad 2 59.Under the elastic force of the elastic gasket 49, the guide block 50 is again fitted with the annular groove 2 43 until the gear 41 is disengaged from the rack 1 34 and meshed with the rack 2 35. The guide block 50 reverses in the annular groove 2 43 and slides directly into the spiral groove 44 after being blocked by the pad 2 59, and then returns from the spiral groove 44 to the annular groove 1 42. Thereafter, the guide block 50 slides cyclically in the annular groove 1 42 and continuously contacts the pad 1 58. When the contact switch 1 39 is fitted with the contact switch 2 40, the electromagnet 53 is energized to generate suction, so that the permanent magnet 54 drives the support rod 55 to slide into the fixed sleeve 2 52 while stretching the spring 2 56, and the arc clamp 57 slides accordingly and clamps the end of the workpiece. When the contact switch 1 39 is disengaged from the contact switch 2 40, the electromagnet 53 is de-energized, and the permanent magnet 54 is reset under the pulling force of the spring 2 56, and the arc clamp 57 moves away from the workpiece.
