Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and in particular to a parts processing device for fuze production. Background Art

[0002] A manipulator is an automatic device that can imitate certain movements and functions of human hands and arms, and is used to grasp, move objects, or operate tools according to fixed procedures. It is mainly used in the fields of machinery manufacturing, light industry, and atomic energy. It mainly consists of three parts: an actuator, a drive mechanism, and a control system. It can replace humans in heavy labor to achieve mechanization and automation of production.

[0003] In the related technology, the fuse processing process requires a robot to clamp the fuse into the mold, and then transfer the mold containing the fuse to the processing table. Due to the large number of fuses, the existing robot needs to cooperate with the clamping tool to assemble each fuse on the mold in turn, the path setting is long, and the work efficiency is low.

[0004] A Chinese patent with 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 adsorption component. The fixing frame is provided with a through step assembly cavity for matching and assembling the suction cup assembly. The depth of the step assembly cavity is less than the length of the suction cup assembly so that part of the suction cup assembly is exposed; the auxiliary adsorption component is connected to the fixing frame. The auxiliary adsorption component is provided with a first through hole. The first through hole is used to enclose the exposed part of the suction cup assembly to perform auxiliary sealing when the suction cup assembly performs vacuum adsorption operation.

[0005] The composite suction cup described above encloses an auxiliary suction piece within the exposed portion of the suction cup assembly. When the internal suction cup assembly leaks during suction, the auxiliary suction piece further forms a sealed cavity to hold the object. This makes the composite suction cup suitable for a variety of surfaces and improves its utilization. However, when the composite suction cup is used to hold a workpiece with a through hole on its end face, the suction cup located at the through hole is difficult to seal due to the presence of the through hole, resulting in a loss of suction capacity and a risk of the workpiece falling off. Summary of the Invention

[0006] The present invention provides a parts processing device for fuze production, aiming to solve the problem in the related art that a suction cup is easily ineffective when adsorbing a workpiece with a through hole on its end face.

[0007] The parts processing device for fuze production of the present invention comprises: a mechanical arm, a mounting seat and an adsorption component;

[0008] The robotic arm is used to drive the adsorption component to move freely in space, the mounting seat is connected to the robotic arm, the adsorption component is arranged on the mounting seat, and the adsorption component is used to adsorb the workpiece;

[0009] The adsorption assembly includes a fixed plate and a suction cup unit, the fixed plate is connected to the mounting seat, and the suction cup unit includes a sealing shell, a movable cylinder, a first suction cup, a second suction cup and a first sealing member, the sealing shell is connected to the fixed plate, the movable cylinder is arranged in the sealing shell, a first air channel is provided in the sealing shell, the first suction cup is arranged at the bottom of the movable cylinder and is communicated with the first air channel, the second suction cup is arranged at the bottom of the sealing shell, and there is an annular space between the first suction cup and the second suction cup. The sealing shell is also provided with a second air channel, and the two ends of the second air channel are respectively communicated with the first air channel and the annular space, the first sealing member slides in the first air channel, the first sealing member is connected to the sealing shell by a first elastic member, the first seal can close the first air channel or the second air channel, when the first seal closes the first air channel, the second suction cup can adsorb the workpiece, and when the first seal closes the second air channel, the first suction cup can adsorb the workpiece.

[0010] Beneficial effect: When adsorbing the workpiece, the first suction cup of some suction cup units is in close contact with the end face of the workpiece, and this part of the suction cup units performs the adsorption operation normally. The first suction cup of the other part of the suction cup units has a through hole for the workpiece. After negative pressure is formed in the first suction cup of this part of the suction cup units, the outside air will be continuously drawn into the first air duct through the through hole of the workpiece. Under the push of the air, the first sealing member overcomes the elastic force of the first elastic member and moves in the first air duct, and closes the first air duct, and opens the second air duct. At this time, the annular space between the second suction cup and the first suction cup can adsorb the end face of the workpiece on the side of the through hole, avoiding the failure to generate suction in this area, and thus avoiding the workpiece falling off due to insufficient suction.

[0011] Preferably, the first sealing member is a cylindrical structure, the diameter of the first sealing member is smaller than the diameter of the first air duct, a first sealing ring is provided in the first air duct, the top end of the first sealing member can stop against the first sealing ring, the second air duct is provided with a first opening on the side wall of the first air duct, 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 sealing member, the second sealing ring is connected to the first sealing member through a connecting rod, and the second sealing ring can close the first opening.

[0012] The effect is that when the first elastic member is in a natural state, the first seal is out of contact with 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 duct. When the first suction cup continues to input air into the first air duct, the first seal gradually approaches the first sealing ring under the push of the air. When the first seal and the first sealing ring stop, the first air duct is closed. At this time, the first opening is exposed, and the first air duct is connected with the second air duct, so that negative pressure is formed in the annular space between the second suction cup and the first suction cup, and the adsorption operation continues.

[0013] Preferably, a first matching cavity is provided in the sealing shell, and a first outer edge is provided at the top end of the movable cylinder. The first outer edge is slidably fitted in the first matching cavity and is connected to the sealing shell through an elastic member. A first connecting channel is provided in the sealing shell, one end of the first connecting channel is connected to the first air duct, and the other end thereof is connected to the first matching cavity. The first connecting channel is provided with a second opening on the side wall of the first air duct, and the height of the second opening is the same as that of the first opening. The second sealing ring can close the second opening.

[0014] The effect is that while the first air duct is closed, the second opening is exposed, so that negative pressure is formed in the first matching 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 the second suction cup from generating a gap when adsorbing the workpiece, resulting in a decrease in suction force.

[0015] Preferably, an air extraction device is provided in the mounting seat, the air extraction device can be communicated with the sealing shell, and the air extraction device is used to generate negative pressure.

[0016] Preferably, the fixing plate and the mounting seat are provided with a detection assembly, and the detection assembly includes a first connecting tube, a second connecting tube and a second sealing member. The first connecting tube is provided on the mounting seat and is connected to the air extraction device. The second connecting tube is provided on the fixing plate and is connected to part of the sealing shell. A matching ring groove is provided in the first connecting tube, and the second connecting tube is slidably fitted in the matching ring groove. The second sealing member is slidably fitted in the first connecting tube and is connected to the first connecting tube through a third elastic member. The second sealing member can close the first connecting tube. A second connecting channel is provided in the first connecting tube, and the second connecting channel can connect the first connecting tube and the matching ring groove.

[0017] The effect is that by setting up a detection component, when the adsorption unit is not in contact with the workpiece, air will continue to be input into the first connecting tube. The air can push the second sealing component to close the first connecting tube, thereby connecting the second connecting channel with the first connecting tube. Under the action of negative pressure, the second connecting tube is gradually retracted into the first connecting tube, thereby lifting the fixed plate and the suction cup unit upward, preventing the adsorption unit that is not in contact with the workpiece from affecting the normal operation of other adsorption units.

[0018] Preferably, an air pressure balancing pipeline is provided on the fixed plate, and the air pressure balancing pipeline includes a first tube and a second tube, the first tube is connected to the first connecting tube, the second tube is slidably matched with the first tube, and is connected to the other sealing shells on the fixed plate, the first tube is provided with an air vent, a slider is provided in the vent, the slider at least partially extends into the air pressure balancing pipeline, and is connected to the first tube through a fourth elastic member, the slider can close the vent, and the second tube can push the slider to open the vent.

[0019] The effect is that by setting up an air pressure balance pipeline, the air pressure balance pipeline is connected to the first connecting tube when the first connecting tube is closed. When the fixed plate is lifted upward, the second tube is retracted into the first tube and pushes the slider to move outward, thereby opening the air vent. The air pressure balance pipeline is connected to the outside world, so that the first suction cup and the second suction cup lose suction, further preventing the adsorption components that are not in contact with the workpiece from affecting the normal operation of other adsorption components, and also avoiding the adsorption of impurities.

[0020] Preferably, a plurality of the adsorption components are distributed at intervals on the mounting base.

[0021] The effect is that by setting up multiple adsorption components, multiple workpieces can be adsorbed at one time, thereby realizing the transfer of multiple workpieces in one transfer process, reducing the repeated travel of the workpieces, saving transportation time, and improving transportation efficiency. After the workpiece is transferred from the positioning frame to the mold, multiple adsorption components can also adsorb the mold and realize the transfer of the mold.

[0022] Preferably, the robotic arm includes a rotating base, a first arm, a second arm and a third arm, the first arm is rotatably connected to the rotating base, the second arm is rotatably connected to the first arm, the third arm is rotatably connected to the second arm, and the mounting base is rotatably engaged with the third arm.

[0023] Preferably, a telescopic mechanism is further provided between the third arm and the mounting seat, and the telescopic mechanism is used to drive the mounting seat to move closer to or away from the third arm.

[0024] Preferably, it further includes a positioning frame and a conveyor belt, the positioning frame is provided with a plurality of positioning holes distributed at intervals, the size of the positioning holes is the same as the outline of the workpiece, the workpiece can be inserted into the positioning holes, and the conveyor belt is used to transport the positioning frame.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are:

[0026] According to the parts processing device for fuse production of the present invention, when adsorbing the workpiece, the first suction cup of some suction cup units is in close contact with the end face of the workpiece, and this part of the suction cup units performs the adsorption operation normally. The first suction cup of the other part of the suction cup units has a through hole of the workpiece. After negative pressure is formed in the first suction cup of this part of the suction cup units, the outside air will be continuously drawn into the first air duct through the through hole of the workpiece. Under the push of the air, the first sealing member overcomes the elastic force of the first elastic member and moves in the first air duct, and closes the first air duct, and the second air duct is opened. At this time, the annular space between the second suction cup and the first suction cup can adsorb the end face of the workpiece on the side around the through hole, avoiding the inability to generate suction in this area, and thus avoiding the workpiece falling off due to insufficient suction.

The second sealing ring 326 is fixedly connected to the first sealing member 324 through a connecting rod, and the second sealing ring 326 is tightly attached to the inner wall of the first air duct 3211. When the first sealing member 324 stops at the first sealing ring 323 and blocks the first air duct 3211, the second sealing ring 326 is located above the first opening and the second opening. At this time, the first air duct 3211 is connected to the second air duct 3212 and the first connecting channel 3213.

The inner end of the slider 53 is elliptical and can extend into the first tube 51 through the connection between the vent and the first tube 51, thereby closing the vent. When the first tube 51 and the second tube 52 approach each other, the second tube 52 can stop with the inner end of the slider 53 and squeeze the slider 53, so that the slider 53 extends out of the first tube 51. At this time, the vent is open and the first tube 51 is connected to the outside.

[0045] The implementation principle of the parts processing device for fuze production of the embodiment of the present invention is as follows: the workpiece 100 processed in the previous process is placed in the positioning frame 6, and the positioning frame 6 is transferred to the side of the robot arm 1 by the conveyor belt 7. When the positioning frame 6 moves to the predetermined position, the conveyor belt 7 stops. At this time, the robot arm 1 moves the mounting seat 2 to the top of the positioning frame 6, and 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 hole on each workpiece 100 is located in the first suction cup 327 of the suction cup unit 32 at the corresponding position. At this time, the exhaust device is started, thereby generating negative pressure, and suction is generated by the negative pressure. Under normal circumstances, 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 causes the first suction cup 327 to generate suction, thereby firmly sucking the end face of the workpiece 100. When the through hole of the workpiece 100 is located at the first suction cup 327, the suction cup 327 is in close contact with the first suction cup 327 and the second suction cup 328. When the first suction cup 327 is inserted, the first suction cup 327 continuously sucks air into the first air passage 3211. Under the push of the sucked air, the first sealing member 324 gradually approaches the first sealing ring 323, and the first elastic member 325 is compressed until the first sealing member 324 and the first sealing ring 323 stop, 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 connected to the second air passage 3212 and the first connecting channel 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 the first suction cup 327 and the second suction cup 328 can both be tightly attached to the end face of the workpiece 100. At the same time, the negative pressure draws the air from the annular space between the first suction cup 327 and the second suction cup 328 through the second air duct 3212, and the end face of the workpiece 100 on the side of the through hole is adsorbed by taking the negative pressure of the annular space between the first suction cup 327 and the second suction cup 328.

[0046] The suction assembly 3 at the bottom of the mounting seat 2 that is not in contact with the workpiece 100 continues to pump air, and the extracted air enters the first connecting tube 41 and pushes the second sealing member 44 to gradually approach the third sealing ring 43. The third elastic member 45 is compressed until the second sealing member 44 stops contacting the third sealing ring 43, thereby closing the first connecting tube 41. At this time, the third opening and the fourth opening are opened, and the second connecting channel and the air pressure balance pipeline 5 are connected to the first connecting tube 41. The negative pressure extracts the air in the matching ring groove, thereby causing the second connecting tube 42 to move upward against gravity, causing the second connecting tube 42 to gradually retract into the first connecting tube 41, thereby lifting 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 tube 52 gradually retracts into the first tube 51 and pushes the slider 53 to overcome the elastic force of the fourth elastic member 54 and move outward, thereby opening the vent, allowing the air pressure balance pipeline 5 to communicate with the outside world, preventing the suction cup unit 32 from generating suction to adsorb the positioning frame 6.

[0047] Then the telescopic component contracts, the robot arm 1 moves the mounting plate to directly above the mold 200, and the telescopic component extends, slowly lowering the workpiece 100 and inserting it into the corresponding hole of the mold 200 until the workpiece 100 is completely placed in the mold 200. Then the vacuuming is paused, the adsorption component 3 is reset, and the telescopic component continues to extend until the first suction cup 327 and the second suction cup 328 are tightly attached to the end faces of the workpiece 100 and the mold 200. Then the vacuum device is started again to adsorb the mold 200 together with the workpiece 100. The robot arm 1 moves the mold 200 to the predetermined position, thereby placing the workpiece 100 in the mold 200 and transferring the mold 200 containing the workpiece 100.

A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
