Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and particularly to a part processing device for fuse production. Background Art

[0002] A manipulator refers to an automatic operation device that can imitate some action functions of human hands and arms, and is used to grasp, transport objects or operate tools according to a fixed program. It is mainly applied in fields such as mechanical manufacturing, light industry, and atomic energy. It mainly consists of three major parts: an execution mechanism, a driving mechanism, and a control system. It can replace humans to perform heavy labor to achieve the mechanization and automation of production. In related technologies, the fuse processing process requires a manipulator to clamp a fuse part into a mold, and then transfer the mold carrying the fuse part to a processing table. Due to the large number of fuses, the existing manipulator needs to cooperate with a clamping tool to sequentially assemble individual fuses onto the mold, with a long path setting and low work efficiency.

[0003] Chinese Patent with the authorization announcement number CN109843516B discloses a composite suction cup, a composite suction cup assembly, and a manipulator. The composite suction cup includes: a suction cup assembly, a fixing frame, and an auxiliary suction attachment. The fixing frame is provided with a through stepped assembly cavity for mating and assembling the suction cup assembly. The depth of the stepped assembly cavity is less than the length of the suction cup assembly so that part of the suction cup assembly is exposed; the auxiliary suction attachment is connected to the fixing frame, and the auxiliary suction attachment is provided with a first through hole for enclosing the exposed part of the suction cup assembly to perform auxiliary sealing when the suction cup assembly performs a vacuum adsorption operation.

[0004] The above composite suction cup encloses the auxiliary suction attachment around the exposed part of the suction cup assembly. Then, when the internal suction cup assembly leaks air during the adsorption process, the auxiliary suction attachment further forms a sealing cavity to adsorb an object, so that the composite suction cup is applicable to various different object surfaces and improves the utilization rate of the composite suction cup. However, when the above composite suction cup adsorbs a workpiece with a through hole on the adsorption end face, the suction cup at the through hole is difficult to seal due to the existence of the through hole, thereby losing the adsorption ability and easily having a risk of workpiece detachment. Summary of the Invention

[0005] The present invention provides a part processing device for fuse production, aiming to solve the problem that the suction cup is prone to failure when adsorbing a workpiece with a through hole on the adsorption end face in related technologies.

[0006] The part processing device for fuse production of the present invention includes: a robotic arm, a mounting seat, and an adsorption assembly; The robotic arm is used to drive the adsorption assembly to move freely in space. The mounting seat is connected to the robotic arm, and the adsorption assembly is arranged on the mounting seat. The adsorption assembly is used to adsorb a workpiece; The adsorption assembly includes a fixing plate and a suction cup unit. The fixing plate is connected to the mounting seat. The suction cup unit includes a sealing shell, a movable cylinder, a first suction cup, a second suction cup, and a first seal. The sealing shell is connected to the fixing plate. The movable cylinder is arranged inside the sealing shell. A first air passage is provided inside the sealing shell. The first suction cup is arranged at the bottom of the movable cylinder and is communicated with the first air passage. The second suction cup is arranged at the bottom of the sealing shell. There is an annular space between the first suction cup and the second suction cup. A second air passage is further provided inside the sealing shell. Two ends of the second air passage are respectively communicated with the first air passage and the annular space. The first seal is slidably fitted inside the first air passage. The first seal is connected to the sealing shell through a first elastic member. The first seal can close the first air passage or the second air passage. When the first seal closes the first air passage, the second suction cup can adsorb the workpiece. When the first seal closes the second air passage, the first suction cup can adsorb the workpiece.

[0007] Beneficial effects: When adsorbing the workpiece, the first suction cups of some suction cup units are in close contact with the end face of the workpiece, and these suction cup units normally perform the adsorption operation. The first suction cups of some other suction cup units have through holes of the workpiece. After a negative pressure is formed inside the first suction cups of these suction cup units, the outside air will be continuously drawn into the first air passage through the through holes of the workpiece. Under the push of the air, the first seal moves inside the first air passage against the elastic force of the first elastic member and closes the first air passage, and the second air passage is opened. At this time, the annular space between the second suction cup and the first suction cup can adsorb the end face on the periphery of the through hole of the workpiece, avoiding the inability to generate suction in this area, and further avoiding the workpiece falling off due to insufficient suction.

[0008] Preferably, the first seal is of a cylindrical structure. The diameter of the first seal is smaller than the diameter of the first air passage. A first sealing ring is provided inside the first air passage. The top end of the first seal can abut against the first sealing ring. The second air passage has a first opening on the side wall of the first air passage, and the height of the first opening is higher than the height of the sealing ring. A second sealing ring is provided above the first seal. The second sealing ring is connected to the first seal through a connecting rod. The second sealing ring can close the first opening.

[0009] The effect is that when the first elastic member is in its natural state, the first seal is disengaged from the first sealing ring. At this time, the air flow can flow through the gap between the first seal and the inner wall of the first air passage. When the first suction cup continuously inputs air into the first air passage, under the push of the air, the first seal gradually approaches the first sealing ring. When the first seal abuts against the first sealing ring, the first air passage is closed. At this time, the first opening is exposed, and the first air passage is communicated with the second air passage, so that a negative pressure is formed in the annular space between the second suction cup and the first suction cup, and the adsorption operation continues.

[0010] Preferably, a first fitting cavity is provided in the sealing shell. A first outer edge is provided at the top end of the movable cylinder. The first outer edge is slidably fitted in the first fitting cavity and is connected to the sealing shell through an elastic member. A first connection channel is provided in the sealing shell. One end of the first connection channel is communicated with the first air passage, and the other end thereof is communicated with the first fitting cavity. The first connection channel is provided with a second opening on the side wall of the first air passage. The height of the second opening is the same as the height of the first opening. The second sealing ring can close the second opening.

[0011] The effect is that when the first air passage is closed, the second opening is exposed, so that a negative pressure is formed in the first fitting cavity. The negative pressure drives the movable cylinder to move downward, so that the bottom end of the first suction cup is flush with the bottom end of the second suction cup, preventing a gap from being generated when the second suction cup adsorbs the workpiece and causing the suction force to decrease.

[0012] Preferably, an air extraction device is provided in the mounting seat. The air extraction device can be communicated with the sealing shell. The air extraction device is used for generating a negative pressure.

[0013] Preferably, a detection assembly is provided on the fixing plate and the mounting seat. The detection assembly includes a first connection cylinder, a second connection cylinder and a second seal. The first connection cylinder is provided on the mounting seat and is communicated with the air extraction device. The second connection cylinder is provided on the fixing plate and is communicated with a part of the sealing shell. A fitting ring groove is provided in the first connection cylinder. The second connection cylinder is slidably fitted in the fitting ring groove. The second seal is slidably fitted in the first connection cylinder and is connected to the first connection cylinder through a third elastic member. The second seal can close the first connection cylinder. A second connection channel is provided in the first connection cylinder. The second connection channel can communicate the first connection cylinder and the fitting ring groove.

[0014] The effect is that by setting the detection component, when the adsorption unit is not in contact with the workpiece, air will continuously be input into the first connecting cylinder. The air can push the second seal to close the first connecting cylinder, so that the second connecting channel communicates with the first connecting cylinder. Under the negative pressure, the second connecting cylinder gradually retracts into the first connecting cylinder, so that the fixing plate and the suction cup unit are lifted upward, preventing the adsorption unit that is not in contact with the workpiece from affecting the normal operation of other adsorption units.

[0015] Preferably, an air pressure balance pipeline is provided on the fixing plate. The air pressure balance pipeline includes a first pipe and a second pipe. The first pipe communicates with the first connecting cylinder. The second pipe is slidably matched with the first pipe and communicates with other seal housings on the fixing plate. An air vent is provided on the first pipe. A slider is provided in the air vent. At least part of the slider extends into the air pressure balance pipeline and is connected to the first pipe through a fourth elastic member. The slider can close the air vent, and the second pipe can push the slider to open the air vent.

[0016] The effect is that by setting the air pressure balance pipeline, when the first connecting cylinder is closed, the air pressure balance pipeline communicates with the first connecting cylinder. When the fixing plate is lifted upward, the second pipe retracts into the first pipe and pushes the slider to move outward, thereby opening the air vent, and the air pressure balance pipeline communicates with the outside, so that the first suction cup and the second suction cup lose suction, further preventing the adsorption component that is not in contact with the workpiece from affecting the normal operation of other adsorption components, and also being able to avoid adsorbing impurities.

[0017] Preferably, a plurality of the adsorption components are spaced apart and distributed on the mounting seat.

[0018] The effect is that by setting a plurality of adsorption components, a plurality of workpieces can be adsorbed at one time, so as to realize the transfer of a plurality of workpieces in one transfer process, reduce the repeated travel of the workpieces, save transportation time, and improve transportation efficiency. After the workpieces are transferred from the positioning frame to the mold, a plurality of adsorption components can also adsorb the mold and realize the transfer of the mold.

[0019] Preferably, the robotic arm includes a rotating seat, a first arm, a second arm, and a third arm. The first arm is rotatably connected to the rotating seat. The second arm is rotatably connected to the first arm. The third arm is rotatably connected to the second arm. The mounting seat is rotatably matched with the third arm.

[0020] Preferably, a telescopic mechanism is further provided between the third arm and the mounting seat. The telescopic mechanism is used to drive the mounting seat to approach or move away from the third arm.

[0021] Preferably, it further includes a positioning frame and a conveyor belt. A plurality of positioning holes are provided on the positioning frame at intervals. The size of the positioning holes is the same as the contour of the workpiece. The workpiece can be inserted into the positioning holes, and the conveyor belt is used to transfer the positioning frame.

[0022] Adopting the above technical solution, the beneficial effects of the present invention are as follows: According to the part processing device for fuse production of the present invention, when adsorbing the workpiece, the first suction cups of some suction cup units are in close contact with the end face of the workpiece, and these suction cup units normally perform the adsorption operation. The first suction cups of another part of the suction cup units have through holes of the workpiece. After a negative pressure is formed in the first suction cups of these suction cup units, the outside air will be continuously drawn into the first air passage through the through holes of the workpiece. Driven by the air, the first seal moves in the first air passage against the elastic force of the first elastic member and closes the first air passage, and the second air passage is opened. At this time, the annular space between the second suction cup and the first suction cup can adsorb the end face on the periphery of the through hole of the workpiece, avoiding the inability to generate suction in this area, and further avoiding the workpiece falling off due to insufficient suction.

The conveyor belt 7 is located beside the robot arm 1, and a plurality of positioning frames 6 are distributed at intervals on the conveyor belt 7.

[0034] As Figure 3As shown, the mounting base 2 is of a rectangular structure. An air extraction device is provided on the mounting base 2. The air extraction device is a vacuum generator in conventional technology. A plurality of adsorption components 3 are evenly spaced and distributed on the mounting base 2. A sealed air path is provided inside the mounting base 2. Each adsorption component 3 is communicated with the air extraction device through the sealed air path.

[0035] As Figures 4 to 7As shown, the adsorption assembly 3 includes a fixing plate 31 and a suction cup unit 32. The fixing plate 31 is of a square structure, and multiple suction cup units 32 are evenly spaced and distributed on the fixing plate 31. The suction cup unit 32 includes a sealing shell 321, a movable cylinder 322, a first suction cup 327, a second suction cup 328, and a first seal 324. The sealing shell 321 is of a cylindrical structure, and a first ventilation channel 3211 in the shape of a circular hole is provided inside it. The first ventilation channel 3211 penetrates through the top and bottom ends of the sealing shell 321. An annular sliding groove is also provided in the sealing shell 321. The diameter of the annular sliding groove is larger than the circumference of the first ventilation channel 3211. The annular sliding groove and the first ventilation channel 3211 are coaxially distributed. The movable cylinder 322 is slidably fitted in the annular sliding groove and is elastically connected to the sealing shell 321 through a second elastic member. The second elastic member is a spring, one end of which is fixedly connected to the top end of the movable cylinder 322, and the other end of which is fixedly connected to the sealing shell 321. The movable cylinder 322 can move axially relative to the sealing shell 321 along the sealing shell 321. A first fitting cavity is also provided on the outer peripheral side of the annular sliding groove of the sealing shell 321. A first limiting ring is fixedly arranged in the first fitting cavity. The bottom end of the first limiting ring is fixedly connected to the sealing shell 321. The first limiting ring is sleeved on the movable cylinder 322 and is slidably fitted with the movable cylinder 322. The top end of the movable cylinder 322 is also provided with a first outer edge, and the outer end of the first outer edge extends downward, thereby forming an annular groove structure between the first outer edge and the movable cylinder 322. The first limiting ring can extend into the annular groove. The first suction cup 327 is fixedly connected to the bottom end of the movable cylinder 322 and is fixedly connected to the movable cylinder 322. The size of the second suction cup 328 is larger than that of the first suction cup 327. The second suction cup 328 is fixedly connected to the bottom end of the sealing shell 321. The first suction cup 327 and the movable cylinder 322 are coaxially distributed. The second suction cup 328 and the first suction cup 327 are coaxially distributed. An annular space is formed between the first suction cup 327 and the second suction cup 328. A sealing ring is also provided in the first ventilation channel 3211. The sealing ring is fixedly arranged in the first ventilation channel 3211. The first seal 324 is of a cylindrical structure, and its diameter is smaller than the diameter of the first ventilation channel 3211. The first seal 324 is arranged in the first ventilation channel 3211 and is located below the sealing ring. The first seal 324 is elastically connected to the sealing ring through a first elastic member 325. The first elastic member 325 is a spring, one end of which is fixedly connected to the top end of the first seal 324, and the other end of which is fixedly connected to the bottom surface of the sealing ring. The first seal 324 can move axially in the first ventilation channel 3211 along the first ventilation channel 3211. When the first seal 324 moves upward to the limit, it can abut against the sealing ring. At this time, the first seal 324 and the sealing ring act together to block the first ventilation channel 3211.A second ventilation passage 3212 and a first connection passage 3213 are also provided inside the sealed housing 321. The top end of the second ventilation passage 3212 has a first opening on the side wall of the first ventilation passage 3211. The height of the first opening is higher than the height of the sealing ring. The bottom end of the second ventilation passage 3212 communicates with the annular space between the first suction cup 327 and the second suction cup 328. The top end of the first connection passage 3213 has a second opening on the side wall of the first ventilation passage 3211. The second opening has the same height as the first opening in the first ventilation passage 3211, and they are distributed oppositely. The bottom end of the first connection passage 3213 communicates with the bottom end of the first mating cavity. A second sealing ring 326 is provided above the first seal 324. The second sealing ring 326 is fixedly connected to the first seal 324 through a connecting rod. The second sealing ring 326 is in close contact with the inner wall of the first ventilation passage 3211. When the first seal 324 abuts against the first sealing ring 323 and blocks the first ventilation passage 3211, the second sealing ring 326 is located above the first opening and the second opening. At this time, the first ventilation passage 3211 communicates with the second ventilation passage 3212 and the first connection passage 3213. When the first seal 324 is disengaged from the first sealing ring 323, the first ventilation passage 3211 remains unobstructed. At this time, the second sealing ring 326 can cover the first opening and the second opening, thereby closing the second ventilation passage 3212 and the first connection passage 3213.

[0036] Such as Figure 4 , Figure 7 and Figure 8As shown in the figure, a detection component 4 is further provided between the fixing plate 31 and the mounting seat 2. The detection component 4 includes a first connecting cylinder 41, a second connecting cylinder 42 and a second seal 44. The first connecting cylinder 41 is fixedly arranged on the mounting seat 2 and is communicated with the air extraction device through a sealed air path. The second connecting cylinder 42 is fixedly arranged on the fixing plate 31. A first air path 311 is arranged in the fixing plate 31. The second connecting cylinder 42 can be communicated with a part of the sealed housing 321 through the first air path 311. A mating ring groove is arranged at the bottom end of the first connecting cylinder 41. The second connecting cylinder 42 can extend into the mating ring groove and is slidably matched with the first connecting cylinder 41. The second connecting cylinder 42 can move relative to the first connecting cylinder 41 along the axial direction of the first connecting cylinder 41. A third seal ring 43 is fixedly arranged in the first connecting cylinder 41. The second seal 44 is a cylindrical structure and has the same structure as the first seal 324. The diameter of the second seal 44 is smaller than the inner diameter of the first connecting cylinder 41. The second seal 44 is located below the third seal ring 43 and is elastically connected to the third seal ring 43 through a third elastic member 45. The third elastic member 45 is a spring. One end of the spring is fixedly connected to the top end of the second seal 44, and the other end of the spring is fixedly connected to the bottom surface of the third seal ring 43. The top end of the second seal 44 can abut against the bottom surface of the third seal ring 43, thereby blocking the first connecting cylinder 41. A second connecting passage 411 is arranged in the first connecting cylinder 41. One end of the second connecting passage 411 is provided with a third opening on the inner side wall of the first connecting cylinder 41, and the other end of the second connecting passage 411 is communicated with the top end of the mating ring groove. A fourth seal ring 46 is arranged above the second seal 44. The fourth seal ring 46 is fixedly connected to the second seal 44 through a connecting rod. The fourth seal ring 46 is in close contact with the inner side wall of the first connecting cylinder 41. When the second seal 44 abuts against the third seal ring 43 and closes the first connecting cylinder 41, the fourth seal ring 46 is separated from the third opening. At this time, the first connecting cylinder 41 is communicated with the second connecting passage 411. When the second seal 44 is separated from the third seal ring 43, the first connecting cylinder 41 remains in a smooth state. At this time, the fourth seal ring 46 can cover the third opening, thereby closing the second connecting passage 411. A second limiting ring is further arranged on the outer side wall of the second connecting cylinder 42. When the second connecting cylinder 42 moves downward to the limit, the second limiting ring abuts against the bottom surface of the first connecting cylinder 41, thereby restricting the second connecting cylinder 42 from continuing to move downward and preventing the second connecting cylinder 42 from separating from the first connecting cylinder 41.

[0037] When the first elastic member 325 is in a natural state, the first seal 324 is located below the first seal ring 323 and is separated from the first seal ring 323. At this time, the first air passage 3211 remains in a smooth state. When the second elastic member is in a natural state, the top end of the movable cylinder 322 abuts against the top surface of the first mating cavity.

[0038] As Figure 4 、 Figure 7And Figure 8 As shown, an air pressure balance pipeline 5 is further provided on the fixing plate 31. The air pressure balance pipeline 5 includes a first pipe 51 and a second pipe 52. The top end of the first pipe 51 is fixedly connected to the first connecting cylinder 41, and the top end of the first pipe 51 communicates with the inner hole of the first connecting cylinder 41. There is a fourth opening on the inner side wall of the first connecting cylinder 41, and the height of the fourth opening in the first connecting cylinder 41 is the same as the height of the third opening. When the fourth sealing ring 46 shields the third opening, the fourth sealing ring 46 can also shield the fourth opening. The second pipe 52 is provided on the fixed seat. The outer diameter of the second pipe 52 is the same as the inner diameter of the first pipe 51. The top end of the second pipe 52 extends into the first pipe 51 and is slidably matched with the first pipe 51. A second air path 312 is provided in the fixing plate 31. The remaining sealing cases 321 not connected to the second connecting cylinder 42 are communicated with the air pressure balance pipeline 5 through the second air path 312. An air vent is provided on the side wall of the first pipe 51. A slider 53 is provided in the air vent. The slider 53 is communicated with the outer end of the air vent through a fourth elastic member 54. The inner end of the slider 53 is elliptical and can extend into the first pipe 51 through the connection part of the air vent and the first pipe 51 to close the air vent. When the first pipe 51 and the second pipe 52 approach each other, the second pipe 52 can abut against the inner end of the slider 53 and squeeze the slider 53, so that the slider 53 extends out of the first pipe 51. At this time, the air vent is opened, and the first pipe 51 communicates with the outside.

[0039] The implementation principle of the part processing device for fuse production in the embodiment of the present invention is as follows: The workpiece 100 completed in the previous process is placed in the positioning frame 6. The positioning frame 6 is transported to the side of the robotic arm 1 through the conveyor belt 7. When the positioning frame 6 moves to the predetermined position, the conveyor belt 7 stops. At this time, the robotic arm 1 moves the mounting seat 2 to directly above the positioning frame 6. The telescopic mechanism 105 drives the mounting seat 2 to gradually approach the positioning frame 6 until the adsorption component 3 at the bottom of the mounting seat 2 is in close contact with the workpiece 100 on the positioning frame 6. Each workpiece 100 corresponds to an adsorption component 3, and the through holes on each workpiece 100 are located in the first suction cup 327 of the corresponding suction cup unit 32. At this time, the air extraction device is started to generate negative pressure, and suction is generated through the negative pressure. Usually, the end face of the workpiece 100 is in close contact with the first suction cup 327 and the second suction cup 328. The negative pressure makes the first suction cup 327 generate suction to firmly suck the end face of the workpiece 100. When the through hole of the workpiece 100 is located in the first suction cup 327, the first suction cup 327 continuously sucks air into the first air passage 3211. Driven by the sucked air, the first seal 324 gradually approaches the first sealing ring 323, and the first elastic member 325 is compressed until the first seal 324 abuts against the first sealing ring 323, thereby blocking the first air passage 3211. At the same time, the first opening and the second opening are exposed, and the first air passage 3211 is communicated with the second air passage 3212 and the first connection passage 3213. Under the action of negative pressure, the movable cylinder 322 slides downward until the bottom ends of the first suction cup 327 and the second suction cup 328 are flush, so that both the first suction cup 327 and the second suction cup 328 can be in close contact with the end face of the workpiece 100. At the same time, the negative pressure extracts the air in the annular space between the first suction cup 327 and the second suction cup 328 through the second air passage 3212, and adsorbs the end face on the periphery of the through hole of the workpiece 100 by taking the negative pressure in the annular space between the first suction cup 327 and the second suction cup 328.

[0040] The adsorption component 3 at the bottom of the mounting seat 2 that is not in contact with the workpiece 100 continuously extracts air. The extracted air enters the first connecting cylinder 41 and pushes the second seal 44 to gradually approach the third sealing ring 43. The third elastic member 45 is compressed until the second seal 44 abuts against the third sealing ring 43, thereby closing the first connecting cylinder 41. At this time, the third opening and the fourth opening are opened, and the second connecting passage and the air pressure balance pipeline 5 are communicated with the first connecting cylinder 41. The negative pressure extracts the air in the mating annular groove, so that the second connecting cylinder 42 moves upward against the gravity, and the second connecting cylinder 42 gradually retracts into the first connecting cylinder 41, thereby raising the fixing plate 31 and the suction cup unit 32 to prevent the suction cup unit 32 from adsorbing the positioning frame 6. When the fixing plate 31 moves upward, the second pipe 52 gradually retracts into the first pipe 51 and pushes the slider 53 to move outward against the elastic force of the fourth elastic member 54, thereby opening the air vent, so that the air pressure balance pipeline 5 is communicated with the outside, preventing the suction cup unit 32 from generating suction to suck the positioning frame 6.

[0041] Subsequently, the telescopic component contracts, and the robotic arm 1 moves the mounting plate to directly above the mold 200. The telescopic component extends, slowly lowers the workpiece 100 and inserts it into the corresponding hole of the mold 200 until the workpiece 100 is completely placed inside the mold 200. Then, the air extraction is paused, the adsorption component 3 resets, and the telescopic component continues to extend until the first suction cup 327 and the second suction cup 328 are closely attached to the end faces of the workpiece 100 and the mold 200. Then, the air extraction device is started again to adsorb the mold 200 together with the workpiece 100. The robotic arm 1 moves the mold 200 to a predetermined position, thereby realizing placing the workpiece 100 into the mold 200 and transferring the mold 200 containing the workpiece 100.
