Description

Technical Field

[0001] The present invention relates to the technical field of PCB micro-drill processing equipment, in particular to a full-automatic micro-drill shank welding machine. Background Art

[0002] Currently, cemented carbide is the most commonly used material for PCB micro-drills. However, due to the high cost of cemented carbide raw materials, only the micro-drill blade is made of cemented carbide (WC-Co cemented carbide), while the micro-drill shank is made of steel. During the welding production process of the micro-drill blade and the micro-drill shank, it is preferred to use a micro-drill blade feeding and clamping mechanism to clamp the micro-drill blade, and a micro-drill shank feeding and clamping mechanism to clamp the micro-drill shank, and then weld the micro-drill blade and the micro-drill shank together. Traditional micro-drill blade and shank welding machines use manual loading and manual collection, which is not only labor-intensive and has low production efficiency, but also has high production costs. At the same time, the participation of an operator is required during the welding process of the micro-drill blade and the micro-drill shank. The strong light, high temperature, and toxic gases generated by the micro-drill blade and the micro-drill shank during welding can cause harm to the operator. Summary of the Invention

DETAILED DESCRIPTION

[0038] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a fully automatic micro-drill blade handle welding machine, which includes a workbench 1 and a plurality of micro-drill blade handle welding devices arranged on the workbench 1; the micro-drill blade handle welding devices include a micro-drill blade feeding clamping mechanism 2, a micro-drill handle feeding clamping mechanism 3, a receiving mechanism 4, a grinding mechanism 5, a blade feeding vibration plate 6, and a handle feeding vibration plate 7; the micro-drill blade feeding clamping mechanism 2, the micro-drill handle feeding clamping mechanism 3, the receiving mechanism 4, the grinding mechanism 5, the blade feeding vibration plate 6, and the handle feeding vibration plate 7 are all installed on the workbench 1;

[0040] The handle feeding vibration plate 7 is used to arrange the micro-drill handles in order and transport them to the micro-drill handle feeding clamping mechanism 3; the micro-drill handle feeding clamping mechanism 3 is used to clamp the micro-drill handles transported by the handle feeding vibration plate 7; the blade feeding vibration plate 6 is used to arrange the micro-drill blades in order and transport them to the micro-drill blade feeding clamping mechanism 2; the micro-drill blade feeding clamping mechanism 2 is used to clamp the micro-drill blades transported by the blade feeding vibration plate 6, and the micro-drill blade feeding clamping mechanism 2 is also used to feed the micro-drill blades into the micro-drill The micro-drill blade clamped by the material clamping mechanism 2 abuts against the micro-drill shank clamped by the micro-drill shank feeding clamping mechanism 3; the micro-drill blade feeding clamping mechanism 2 and the micro-drill shank feeding clamping mechanism 3 are respectively connected to an external power supply. After the micro-drill blade clamped by the micro-drill blade feeding clamping mechanism 2 abuts against the micro-drill shank clamped by the micro-drill shank feeding clamping mechanism 3, the micro-drill blade feeding clamping mechanism 2 and the micro-drill shank feeding clamping mechanism 3 are respectively energized to electrically weld the micro-drill blade and the micro-drill shank together to form a micro-drill finished product;

[0041] The receiving mechanism 4 is used to clamp and collect the finished micro-drills, and the grinding mechanism 5 is used to grind the micro-drill shanks of the finished micro-drills clamped by the receiving mechanism 4 .

[0042] In actual operation, the handle feeding vibration disk 7 arranges the micro-drill handles in an orderly manner and conveys them to the micro-drill handle feeding and clamping mechanism 3. The micro-drill handle feeding and clamping mechanism 3 clamps the micro-drill handles conveyed by the handle feeding vibration disk 7. The blade feeding vibration disk 6 arranges the micro-drill blades in an orderly manner and conveys them to the micro-drill blade feeding and clamping mechanism 2. The micro-drill blade feeding and clamping mechanism 2 clamps the micro-drill blades conveyed by the blade feeding vibration disk 6. Then, the micro-drill blade feeding and clamping mechanism 2 abuts the micro-drill blade clamped by the micro-drill blade feeding and clamping mechanism 2 against the micro-drill handle clamped by the micro-drill handle feeding and clamping mechanism 3. After the micro-drill blade and the micro-drill handle abut, the micro-drill blade feeding and clamping mechanism 2 and the micro-drill handle feeding and clamping mechanism 3 are respectively energized to electrically weld the micro-drill blade and the micro-drill handle together to form a finished micro-drill. Then the receiving mechanism 4 clamps the finished micro-drill and collects the finished micro-drill. Before the receiving mechanism 4 collects the finished micro-drill, the grinding mechanism 5 grinds the micro-drill shank of the finished micro-drill clamped by the receiving mechanism 4.

[0043] The fully automatic micro-drill blade and handle welding machine of the present application can realize automatic loading and unloading, which not only reduces labor intensity and improves production efficiency, but also reduces production costs. At the same time, the micro-drill blade and the micro-drill handle do not require operator participation during the welding process, thus avoiding the strong light, high temperature and toxic gases generated by the micro-drill blade and the micro-drill handle during welding and causing harm to the operator.

[0044] like Figures 3 to 5As shown, in this embodiment, the micro drill blade feeding and clamping mechanism 2 includes a blade mounting plate 21, a mounting seat assembly 22, a mounting seat driving mechanism 23, a blade bearing block 24, a blade intermittent feeding block 25, a blade intermittent feeding block driving mechanism 26, a blade storage block 27, a blade ejector pin 28, a blade ejector pin driving mechanism 29, a blade pressing block 210, a blade pressing block driving mechanism 211 and a pressure detection device 212;

[0045] The mounting seat driving mechanism 23 is arranged on the workbench 1 and is used to drive the mounting seat assembly 22 to move, and the blade mounting plate 21 is slidably connected to the mounting seat assembly 22; the blade bearing block 24, the blade intermittent feeding block 25 and the blade storage block 27 are respectively arranged at intervals on the blade mounting plate 21, and the blade intermittent feeding block 25 is located between the blade bearing block 24 and the blade storage block 27; the blade intermittent feeding block 25 is provided with a first blade storage hole 251, and the first blade storage hole 251 passes through the blade intermittent feeding block 25; the blade storage block 27 is provided with a second blade storage hole 271 and a blade push pin through hole 272, and the second blade storage hole 271 and the blade push pin through hole 272 both pass through the blade storage block 27; the blade intermittent feeding block driving mechanism 26 is used The intermittent feeding block 25 of the driving blade is moved so that the first storage hole 251 of the blade is connected to the second storage hole 271 of the blade or the first storage hole 251 of the blade is connected to the blade pusher pin through hole 272; the blade pusher pin driving mechanism 29 is arranged on the blade mounting plate 21 and is used to drive the blade pusher pin 28 to move, and the blade pusher pin 28 is slidably arranged in the blade pusher pin through hole 272; the blade clamping block driving mechanism 211 is arranged on the blade mounting plate 21 and is used to drive the blade clamping block 210 to rotate, and the blade clamping block 210 is used to press the micro drill blade carried by the blade bearing block 24 to the blade bearing block 24, and the blade clamping block 210 is connected to the external power supply; the pressure detection device 212 is arranged on the mounting seat assembly 22 and is used to resist the blade mounting plate 21.

[0046] In actual work, the blade feeding vibration disk 6 arranges the micro-drill blades in order and transports them one by one to the blade second storage hole 271 of the blade storage block 27 through the conveying pipe, and then the blade intermittent feeding block driving mechanism 26 drives the blade intermittent feeding block 25 to move. When the blade first storage hole 251 is connected to the blade second storage hole 271, the micro-drill blade in the blade second storage hole 271 will enter the blade first storage hole 251, and at the same time, the next micro-drill blade in the conveying pipe will enter the blade second storage hole 271. The blade intermittent feeding block driving mechanism 26 then drives the blade intermittent feeding block 25 to continue moving, and the blade intermittent feeding block 25 blocks the blade second storage hole 271, preventing the micro-drill blade from falling out of the blade second storage hole 271. When the blade first storage hole 251 is connected to the blade pusher pin through hole 272, the blade pusher pin driving mechanism 29 drives the blade pusher pin 28 to slide along the blade pusher pin through hole 272 and the blade first storage hole 251. The sliding blade pusher pin 28 pushes the micro-drill blade in the blade first storage hole 251 onto the blade bearing block 24. The blade pusher pin driving mechanism 29 then drives the blade pusher pin 28 in the reverse direction to reset it, and the blade intermittent feeding block driving mechanism 26 drives the blade intermittent feeding block 25 to move in the reverse direction and prepare to deliver the next micro-drill blade. At the same time, the blade pressing block driving mechanism 211 drives the blade pressing block 210 to rotate so that the blade pressing block 210 presses the micro-drill blade carried by the blade bearing block 24 onto the blade bearing block 24. After the micro-drill blade is pressed, the mounting seat driving mechanism 23 drives the mounting seat assembly 22 to move toward the direction of the micro-drill shank feeding clamping mechanism 3. When the micro-drill blade abuts against the micro-drill shank clamped by the micro-drill shank feeding clamping mechanism 3, the mounting seat driving mechanism 23 continues to drive the mounting seat assembly 22 to move toward the direction of the micro-drill shank feeding clamping mechanism 3. At this time, the blade mounting plate 21 will slide in the opposite direction along the mounting seat assembly 22 and apply a reverse thrust to the pressure detection device 212. The pressure detection device 212 is pressed. The detection device 212 detects the pressure between the micro-drill blade and the micro-drill handle by detecting the reverse thrust of the blade mounting plate 21. When the pressure between the micro-drill blade and the micro-drill handle reaches a set value, the operator energizes the micro-drill blade and the micro-drill handle respectively. Specifically, the external current is transmitted to the micro-drill blade via the blade clamping block 210, and a short circuit occurs between the micro-drill blade and the micro-drill handle, generating high temperature. The high temperature causes the micro-drill blade and the micro-drill handle to be welded together to form a finished micro-drill.

[0047] The micro-drill blade feeding and clamping mechanism 2 of the present application can automatically clamp the micro-drill blade, which not only reduces labor intensity and improves production efficiency, but also reduces production costs.

[0048] Specifically, the blade bearing block 24 is recessed with a plurality of blade retaining grooves 241 , which are spaced apart and arranged on the same side of the blade bearing block 24 . The blade retaining grooves 241 are used to carry the micro-drill blade. In actual operation, the blade pusher pin driving mechanism 29 drives the blade pusher pin 28 to slide along the blade pusher pin through hole 272 and the blade first storage hole 251. The sliding blade pusher pin 28 pushes the micro-drill blade in the blade first storage hole 251 into a blade slot 241 of the blade support block 24. Then, the blade clamping block driving mechanism 211 drives the blade clamping block 210 to rotate so that the blade clamping block 210 presses the micro-drill blade carried by the blade support block 24 into the blade slot 241 of the blade support block 24. The inner walls of the blade slot 241 respectively contact the micro-drill blade, so that the micro-drill blade is clamped more firmly by the blade clamping block 210, which is convenient for subsequent welding work. Specifically, the sizes of the multiple blade slots 241 are different. The operator can select the appropriate blade slot 241 according to the production needs to meet the production needs. Preferably, the blade groove 241 is a V-shaped groove.

[0049] Specifically, the blade storage block 27 is provided with an intermittent feed stopper 273, which is arranged crosswise with the blade storage block 27 and is configured to abut the blade intermittent feed block 25. In actual operation, when the blade intermittent feed block drive mechanism 26 drives the blade intermittent feed block 25 to a set position, the intermittent feed stopper 273 abuts the blade intermittent feed block 25, preventing the blade intermittent feed block 25 from further movement. The provision of the intermittent feed stopper 273 on the blade storage block 27 ensures the stable operation of the blade intermittent feed block 25.

[0050] like Figure 4 As shown, in this embodiment, the blade pressing block 210 includes a blade conductive block 2101 and a blade conductive block connecting rod 2102, and the blade conductive block connecting rod 2102 is made of insulating material; the middle part of the blade conductive block connecting rod 2102 is rotatably connected to the blade mounting plate 21, one end of the blade conductive block connecting rod 2102 is connected to the output end of the blade pressing block driving mechanism 211, and the other end of the blade conductive block connecting rod 2102 is connected to the blade conductive block 2101, and the blade conductive block 2101 is used to press the micro-drill blade carried by the blade supporting block 24 to the blade supporting block 24, and the blade conductive block 2101 is electrically connected to the external power supply.

[0051] During actual use, the blade clamping block driving mechanism 211 drives one end of the blade conductive block connecting rod 2102 to move upward, and the middle part of the blade conductive block connecting rod 2102 rotates along the blade mounting plate 21, and the other end of the blade conductive block connecting rod 2102 drives the blade conductive block 2101 to rotate downward, and the downward rotating blade conductive block 2101 presses the micro-drill blade against the blade supporting block 24; since a current needs to be applied to the blade conductive block 2101, in order to prevent the current of the blade conductive block 2101 from being transmitted to other components of the micro-drill blade feeding and clamping mechanism 2, an insulating blade conductive block connecting rod 2102 is used to isolate the current of the blade conductive block 2101, so that the micro-drill blade feeding and clamping mechanism 2 can work safely and stably.

[0052] like Figure 5 As shown, in this embodiment, the two opposite sides of the blade intermittent feeding block 25 are connected with wear-resistant layers 252 , and the wear-resistant layers 252 on the two opposite sides of the blade intermittent feeding block 25 respectively abut against the blade bearing block 24 and the blade storage block 27 .

[0053] In actual operation, the blade intermittent feed block 25 needs to move frequently, which may cause friction and wear between the blade bearing block 24 and the blade storage block 27, thereby reducing the service life of the blade intermittent feed block 25. In the present application, wear-resistant layers 252 are connected to opposite sides of the blade intermittent feed block 25. The wear-resistant layers 252 protect the blade intermittent feed block 25, thereby increasing the service life of the blade intermittent feed block 25. Specifically, the wear-resistant layers 252 are made of ceramic material, which is inexpensive and wear-resistant.

[0054] like Figures 6 to 8 As shown, in this embodiment, the micro drill handle feeding and clamping mechanism 3 includes a handle bracket 31, a handle storage box 32, a handle bearing block 33, a handle intermittent feeding block 34, a handle intermittent feeding block driving mechanism 35, a handle pushing pin 36, a handle pushing pin driving mechanism 37, a handle pressing block 38 and a handle pressing block driving mechanism 39;

[0055] The handle bracket 31 is arranged on the workbench 1, and the handle storage box 32 is connected to the handle bracket 31. The handle storage box 32 is provided with a handle storage groove 321, and the handle storage groove 321 passes through the handle storage box 32. The handle intermittent feeding block 34 is recessed with a handle receiving groove 341. The handle intermittent feeding block 34 is located between the handle storage box 32 and the handle bracket 31. The handle intermittent feeding block 34 is located below the handle storage groove 321. The handle intermittent feeding block 34 is slidably arranged on the handle bracket 31. The handle intermittent feeding block driving mechanism 35 is installed on the handle bracket 31 and is used to drive the handle intermittent feeding block 34 to slide so that the handle receiving groove 341 is connected to the handle storage tank 321; the handle pushing pin driving mechanism 37 is installed on the handle bracket 31 and is used to drive the handle pushing pin 36 to move, and the handle pushing pin 36 is slidably set in the handle accommodating groove 341; the handle supporting block 33 is connected to the handle bracket 31 and is used to carry the micro-drill handle, and the handle supporting block 33 is located at the discharge end of the handle accommodating groove 341; the handle clamping block driving mechanism 39 is installed on the handle bracket 31 and is used to drive the handle clamping block 38 to rotate, and the handle clamping block 38 is used to clamp the micro-drill handle carried by the handle supporting block 33 to the handle supporting block 33, and the handle clamping block 38 is connected to the external power supply.

[0056] In actual operation, the shank feeding vibration plate 7 arranges the micro-drill shanks in an orderly manner and transports them one by one to the shank storage trough 321 of the shank storage box 32 via the conveying pipe. The micro-drill shanks are stacked one by one in the shank storage trough 321. Then, the shank intermittent feeding block driving mechanism 35 drives the shank intermittent feeding block 34 to move. When the shank receiving trough 341 is connected to the shank storage trough 321, a micro-drill shank stacked in the shank storage trough 321 falls into the shank receiving trough 341. Then, the shank intermittent feeding block driving mechanism 35 drives the shank intermittent feeding block 34 to continue moving. The shank intermittent feeding block 34 blocks the discharge port of the shank storage trough 321, preventing the micro-drill shanks stacked in the shank storage trough 321 from falling out of the shank storage trough 321. When the shank receiving groove 341 moves to the corresponding position of the shank bearing block 33, the shank pusher pin driving mechanism 37 drives the shank pusher pin 36 to slide along the shank receiving groove 341. The sliding shank pusher pin 36 pushes the micro-drill shank in the shank receiving groove 341 onto the shank bearing block 33. Then, the shank pusher pin driving mechanism 37 drives the shank pusher pin 36 in the reverse direction to reset it. The shank intermittent feeding block driving mechanism 35 drives the shank intermittent feeding block 34 in the reverse direction to prepare for delivering the next micro-drill shank. At the same time, the shank pressing block driving mechanism 39 drives the shank pressing block 38 to rotate so that the shank pressing block 38 presses the micro-drill shank carried by the shank bearing block 33 against the shank bearing block 33.

[0057] The micro-drill shank feeding and clamping mechanism 3 of the present application can automatically clamp the micro-drill shank, which not only reduces labor intensity and improves production efficiency, but also reduces production costs.

[0058] Specifically, the handle bracket 31 is connected to a handle ejector guide block 311. The handle ejector guide block 311 defines a guide hole (not shown) in which the handle ejector 36 slides. In actual operation, when the handle ejector drive mechanism 37 drives the handle ejector 36 to move, the moving handle ejector 36 slides along the guide hole of the handle ejector guide block 311. The handle ejector guide block 311 of the present application ensures that the handle ejector 36 moves in the correct direction.

[0059] Specifically, the handle clamping block 38 includes a handle conductive block 381 and a handle conductive block connecting rod 382, ​​and the handle conductive block connecting rod 382 is made of insulating material; the middle part of the handle conductive block connecting rod 382 is rotatably connected to the handle bracket 31, one end of the handle conductive block connecting rod 382 is connected to the output end of the handle clamping block driving mechanism 39, and the other end of the handle conductive block connecting rod 382 is connected to the handle conductive block 381, and the handle conductive block 381 is used to press the micro-drill handle carried by the handle supporting block 33 to the handle supporting block 33, and the handle conductive block 381 is electrically connected to the external power supply. During actual use, the handle clamping block driving mechanism 39 drives one end of the handle conductive block connecting rod 382 to move upward, the middle part of the handle conductive block connecting rod 382 rotates along the handle bracket 31, and the other end of the handle conductive block connecting rod 382 drives the handle conductive block 381 to rotate downward, and the downward rotating handle conductive block 381 presses the micro-drill handle against the handle supporting block 33; since a current needs to be applied to the handle conductive block 381, in order to prevent the current of the handle conductive block 381 from being transmitted to other components of the micro-drill handle feeding and clamping mechanism 3, an insulating handle conductive block connecting rod 382 is used to isolate the current of the handle conductive block 381, so that the micro-drill handle feeding and clamping mechanism 3 can work safely and stably.

[0060] Specifically, the handle support block 33 is recessed with a handle slot 331 for supporting the microdrill handle. The handle slot 331 is a V-shaped groove. In actual operation, the handle pusher pin drive mechanism 37 drives the handle pusher pin 36 to slide along the handle receiving groove 341. The sliding handle pusher pin 36 pushes the microdrill handle within the handle receiving groove 341 into the handle slot 331 of the handle support block 33. The handle pressing block drive mechanism 39 then drives the handle pressing block 38 to rotate, causing the handle conductive block 381 of the handle pressing block 38 to press the microdrill handle carried by the handle support block 33 into the handle slot 331 of the handle support block 33. The inner walls of the handle slot 331 contact the microdrill handle, ensuring that the microdrill handle is more firmly pressed by the handle support block 33, facilitating subsequent welding. Preferably, the handle groove 331 is a V-shaped groove, which has a better impact on the micro-drill handle.

[0061] like Figure 8 As shown, in this embodiment, the handle intermittent feeding block 34 includes a handle intermittent loading block 342 and a guide sliding block 343 connected to the handle intermittent loading block 342, the guide sliding block 343 is driven and connected to the handle intermittent feeding block driving mechanism 35, the handle intermittent loading block 342 and the guide sliding block 343 are cross-arranged, and the handle accommodating groove 341 is recessed inward from the surface of the handle intermittent loading block 342; the handle bracket 31 is recessed with a slide groove (not shown in the figure), and the guide sliding block 343 is slidably arranged in the slide groove.

[0062] In actual operation, when the handle intermittent feed block drive mechanism 35 drives the handle intermittent feed block 34 to move, the guide slide 343 slides along the slide groove of the handle bracket 31, ensuring that the handle intermittent feed block 34 moves in the correct direction. The handle receiving groove 341 of the handle intermittent loading block 342 is used to support the micro-drill handle. Preferably, the handle receiving groove 341 is a V-shaped groove, which has a better impact resistance effect on the micro-drill handle.

[0063] like Figures 9 to 12 As shown, in this embodiment, the material receiving mechanism 4 includes a material receiving mounting base 40, a material receiving box 41, a material clamping hook block 42, an elastic member 43, a material pushing plate 44, a material pushing plate driving mechanism 45, a material pushing ejector 46, a material pushing ejector driving mechanism 47, a material grabbing assembly 48 and a material grabbing assembly driving mechanism 49;

[0064] The material receiving mounting seat 40 is arranged on the workbench 1, and the material receiving box 41 is arranged on the material receiving mounting seat 40. The material receiving box 41 is provided with a material accommodating cavity 411 and a material feeding port 412. The material feeding port 412 communicates with the material accommodating cavity 411 and the outside. The middle part of the material clamping hook block 42 is rotatably connected to the material receiving box 41. One end of the elastic member 43 abuts against the material receiving box 41, and the other end of the elastic member 43 abuts against the upper part of the material clamping hook block 42. The lower part of the material clamping hook block 42 is located at the material feeding port 412.

[0065] The grabbing assembly 48 is used to clamp the finished micro-drill product, and the grabbing assembly driving mechanism 49 is arranged on the material receiving mounting seat 40 and is used to drive the grabbing assembly 48 to move; the pushing pin driving mechanism 47 is arranged on one side of the material receiving mounting seat 40, and the pushing pin driving mechanism 47 is used to drive the pushing pin 46 to move; the pushing plate driving mechanism 45 is arranged on the material receiving box 41 and is used to drive the pushing plate 44 to move, and the pushing plate 44 is slidably arranged at the feed port 412.

[0066] In actual operation, after the micro-drill blade and the micro-drill shank are electrically welded together to form a finished micro-drill, the gripper assembly drive mechanism 49 drives the gripper assembly 48 to move to a set position, whereupon the gripper assembly 48 grips the finished micro-drill. The gripper assembly drive mechanism 49 then drives the gripper assembly 48 in the opposite direction to the grinding mechanism 5, which grinds the micro-drill shank of the finished micro-drill gripped by the gripper assembly 48. Then, the material grabbing assembly driving mechanism 49 continues to drive the material grabbing assembly 48 to move in the opposite direction to the set position, and the material grabbing assembly 48 releases the finished micro-drill product it has gripped. The material pusher pin driving mechanism 47 drives the material pusher pin 46 to move and push the finished micro-drill product gripped by the material grabbing assembly 48 to the feed port 412 of the material receiving box 41. The material pusher plate driving mechanism 45 drives the material pusher plate 44 to move. The movable material pusher plate 44 slides along the feed port 412 and pushes open the material clamping hook block 42. At the same time, the movable material pusher plate 44 pushes the finished micro-drill product in the feed port 412 into the material holding cavity 411 of the material receiving box 41. When the material clamping hook block 42 is pushed open by the material pusher plate 44, the middle portion of the material clamping hook block 42 rotates along the material receiving box 41, and the upper portion of the material clamping hook block 42 squeezes the elastic member 43, causing the elastic member 43 to elastically deform and store elastic potential energy. When the push plate 44 releases the pressure on the material-holding hook block 42, the elastic member 43 releases its elastic potential energy and drives the middle portion of the material-holding hook block 42 to rotate in the opposite direction along the material receiving box 41. The lower portion of the material-holding hook block 42 blocks the feed port 412, thereby preventing the finished micro-drills in the material-holding cavity 411 from escaping from the material receiving box 41. The material receiving mechanism 4 of the present application can realize automatic material receiving, which not only reduces labor intensity but also improves production efficiency.

[0067] like Figure 12 As shown, in this embodiment, the grabbing assembly 48 includes a lower claw block 481, an upper claw block 482 and a grabbing cylinder 483. The lower claw block 481 is driven and connected to the grabbing assembly driving mechanism 49. The lower claw block 481 is provided with two upper claw mounting blocks 4811 at intervals. The middle part of the upper claw block 482 is rotatably connected to the two upper claw mounting blocks 4811 respectively. One end of the upper claw block 482 is connected to the output end of the grabbing cylinder 483, and the other end of the upper claw block 482 is used to press the micro-drill finished product to the lower claw block 481. The grabbing cylinder 483 is provided on the lower claw block 481 and is used to drive the upper claw block 482 to move.

[0068] In actual operation, after the gripper assembly drive mechanism 49 drives the gripper assembly 48 to the set position, the gripper cylinder 483 drives one end of the upper claw block 482 upward. Simultaneously, the middle portion of the upper claw block 482 rotates along the two upper claw mounting blocks 4811. The other end of the upper claw block 482 presses the finished micro-drill against the lower claw block 481. The gripper assembly 48 has a simple structure and can stably and reliably grasp the finished micro-drill.

[0069] Specifically, the lower jaw block 481 is recessed with a micro-drill product holding slot (not shown) for accommodating the micro-drill product. In actual operation, the micro-drill product will be placed in the micro-drill product holding slot of the lower jaw block 481. The inner wall of the micro-drill product holding slot will contact the micro-drill product, so that the micro-drill product is pressed more firmly by the upper jaw block 482.

[0070] like Figure 11 As shown, in this embodiment, the grabbing assembly driving mechanism 49 includes a grabbing connection slider 491 and a grabbing connection slider driving mechanism 492. The grabbing connection slider 491 is slidably connected to the material receiving mounting seat 40. The grabbing connection slider driving mechanism 492 is provided on the material receiving mounting seat 40 and is used to drive the grabbing connection slider 491 to slide. The grabbing assembly 48 is connected to the grabbing connection slider 491; the grabbing connection slider 491 is also provided with a finger cylinder 493, which is used to clamp the micro-drill finished product clamped by the grabbing assembly 48.

[0071] In actual operation, the gripper connecting slider 491 provides a mounting base for the gripper assembly 48 and the finger cylinder 493. After the gripper assembly 48 grasps the finished micro-drill, the finger cylinder 493 further clamps the micro-drill shank of the finished micro-drill. Because the finished micro-drill needs to be polished by the grinding mechanism 5 before entering the material receiving box 41, the gripping of the micro-drill shank by the finger cylinder 493 ensures that the finished micro-drill will not break during the polishing process.

[0072] Specifically, the material grabbing connecting slider driving mechanism 492 is a screw-nut type driving mechanism, which has the characteristics of high transmission efficiency and high precision.

[0073] like Figure 2 、 Figure 13 and Figure 14As shown, in this embodiment, the grinding mechanism 5 includes a reference block 51, a top block 52, a top block driving mechanism 53, a grinder 54 and a grinder moving driving mechanism 55; the reference block 51 is arranged on the workbench 1 or the material receiving mechanism 4, the top block driving mechanism 53 is arranged on the workbench 1 and is used to drive the top block 52 to move closer to or away from the reference block 51, the top block 52 is arranged opposite to the reference block 51, the grinder moving driving mechanism 55 is arranged on the workbench 1 and is used to drive the grinder 54 to move, and the grinder 54 is used to grind the micro-drill shank of the micro-drill product clamped by the material receiving mechanism 4.

[0074] After the microdrill blade and microdrill shank are electrically welded together to form the finished microdrill, the length of the finished microdrill may vary. Therefore, any overly long microdrills need to be polished to ensure that each finished microdrill meets production standards. In actual operation, when the receiving mechanism 4 clamps the finished microdrill and moves it to one side of the reference block 51, the top block driving mechanism 53 drives the top block 52 to move closer to the reference block 51. The moving top block 52 presses against the finished microdrill clamped by the receiving mechanism 4, causing the microdrill blade to contact the reference block 51. After the finished microdrill clamped by the receiving mechanism 4 is corrected, the top block driving mechanism 53 drives the top block 52 to move away from the reference block 51 and reset. As the receiving mechanism 4 continues to move the finished microdrill and passes through the grinder 54, the grinder 54 polishes the finished microdrill clamped by the receiving mechanism 4. The grinder movement driving mechanism 55 can drive the grinder 54 to adjust its position, allowing the grinder 54 to polish microdrills of different lengths to meet production requirements. The grinding mechanism 5 of the present application can automatically grind the finished micro-drills to ensure that the length of each finished micro-drill meets the production standards.

[0075] All technical features in this embodiment can be freely combined according to actual needs.

[0076] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
