Technical Field
[0001] The present invention relates to the field of mechanical arms, and more particularly to an industrial mechanical arm for a production line. Background Art
[0002] Industrial robot arms, also known as industrial manipulators or industrial robot arms, are automated mechanical devices that are widely used in the field of robotics technology.

The tasks they can perform include but are not limited to clamping welding tongs or welding guns for welding, carrying die-cast or stamped parts, laser cutting, spraying, and assembling mechanical parts.
[0003] Industrial robotic arms are usually composed of structures, end-of-arm tools, computer digital controllers, drivers, measurement feedback systems and sensors. They control the movement of each joint through programming to achieve precise positioning and operation.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.
[0034] See also Figures 1 to 9 , an industrial robot arm for a production line, comprising a robot arm body 1, the robot arm body 1 is composed of two mutually hinged arms 101 and a claw 102 hinged at the end of the arm 101, an impact component 2 is arranged inside the claw 102, the impact component 2 comprises a moving groove 21 opened inside the claw 102, and the number of the moving grooves 21 is two;
[0035] The left and right sides of the two movable grooves 21 are fixedly connected with the first return springs 22, the opposite ends of the two first return springs 22 on the same side are fixedly connected with the magnet rods 23, the opposite ends of the two magnet rods 23 are fixedly connected with the top rods 231, the insides of the two movable grooves 21 are fixedly connected with the fixed seats 24, the two fixed seats 24 both penetrate the lower side of the claw 102, and the two magnet rods 23 on the same side are respectively located on the left and right sides of the fixed seat 24.
[0036] By adopting the above technical solution, first, in the process of the robot arm body 1 controlling the movement of the claw 102 through the arm 101, if the claw 102 swings in an up and down state, the two magnet rods 23 inside the moving groove 21 in the claw 102 both move to the same side by inertia, one of which collides with the inner wall of the moving groove 21, and the impact force generated will relieve the inertia generated by the material grabbed by the claw 102, and the other magnet rod 23 and the top rod 231 will enter one side of the fixed seat 24, and finally reset by the first reset spring 22, and repeat the above steps. When the claw 102 moves in the opposite direction, the two magnet rods 23 will move in opposite directions, and one of the magnet rods 23 will hit the other side of the inner wall of the moving groove 21. Since the claw 102 swings up and down, one of the two magnet rods 23 inside the claw 102 will hit the inside of the moving groove 21, and the impact force generated during the collision will relieve the inertia generated by the movement of the claw 102, thereby ensuring the stability of the claw 102 when grabbing the material and avoiding the dislocation of the material due to inertia.
[0037] like Figures 3 to 5 As shown, a locking assembly 25 is disposed inside each of the two fixing seats 24 . The locking assembly 25 includes a clamping slot 251 respectively disposed on the left and right sides of the fixing seat 24 , and the two clamping slots 251 are connected to each other.
[0038] After the magnet rod 23 is moved, it is inserted into the slot 251 in the corresponding direction, and the magnet rod 23 is adsorbed inside the slot 251. A first limiting slot 252 is opened inside the fixing seat 24, and the number of the first limiting slots 252 is four. Two first limiting slots 252 on the same side form a group, and the corresponding two first limiting slots 252 are connected to the same slot 251. The insides of the four first limiting slots 252 are all slidably connected with the moving rods 253, and the outer sides of the four moving rods 253 are all fixedly connected with the guide blocks 254. There are two outer guide blocks 254 of a single moving rod 254, and the moving rod 253 is slidably connected in the same first limiting groove 252 through the two guide blocks 254. After the magnet rod 23 is inserted into the slot 251, the two moving rods 253 are pushed at the same time. The interior of the fixed seat 24 is slidably connected with an extrusion column 255, and the number of the extrusion columns 255 is two. The opposite surfaces of the two extrusion columns 255 are inclined, and the moving rod 253 is pushed by the magnet rod 23 to squeeze the extrusion column 255.
[0039] By adopting the above technical solution, first, when the magnet rod 23 hits the fixing seat 24, it will enter the slot 251 opened on the side of the fixing seat 24, and finally be adsorbed in the slot 251. After the magnet rod 23 enters the slot 251, it will also push the moving rod 253 in the first limiting slot 252, so that the moving rod 253 slides in the first limiting slot 252 through the guide block 254, so that the two moving rods 253 respectively squeeze the inclined surfaces of the two squeezing columns 255, and finally cause the two squeezing columns 255 to move downward, and always ensure the state after the downward movement, when the other magnet rod 23 enters the slot 251 on the other side. During the process, the push rod 231 at the end of the magnet rod 23 will contact the push rod 231 at the end of the other magnet rod 23 and push the push rod 231. At this time, the first return spring 22 will pull the pushed magnet rod 23, and repeat the above steps. The two magnet rods 23 will repeatedly enter the slot 251. As the claw 102 swings up and down, one of the magnet rods 23 will enter the slot 251 and lock the squeezing column 255 through the moving rod 253, so that the squeezing column 255 always remains in the state of moving downward, so that pressure can be applied to the grasped material through the squeezing column 255, further ensuring the stability of the grasped material during movement.
[0040] like Figure 6 As shown, a positioning assembly 26 is disposed inside each of the two fixing seats 24 . The positioning assembly 26 includes two second limiting grooves 261 opened inside the fixing seat 24 . The number of the second limiting grooves 261 is two, and both second limiting grooves 261 pass through the lower side of the fixing seat 24 .
[0041] The two extrusion columns 255 are respectively slidably connected in the two second limiting grooves 261, and the second return springs 262 are fixedly connected to the front and rear sides of the lower end of the extrusion column 255. The other ends of the two second return springs 262 are fixedly connected to the inner side walls of the second limiting grooves 261. The lower sides of the two extrusion columns 255 are commonly connected to the extrusion plate 263, and the shape of the extrusion plate 263 fits the lower side of the fixed seat 24.
[0042] By adopting the above technical solution, first, in the process of the moving rod 253 squeezing the squeezing plate 263, the two squeezing columns 255 will slide in the two second limiting grooves 261 and squeeze the second return spring 262. Since the two squeezing columns 255 are fixed to the squeezing plates 263, after the squeezing columns 255 move downward, the squeezing plates 263 will also be pushed out from the bottom of the fixed seat 24 and squeeze the material. After the moving rod 253 is disengaged from the squeezing columns 255, the second return spring 262 inside the second limiting groove 261 will lift the squeezing columns 255, so that the squeezing plates 263 re-enter the fixed seat 24. Since the squeezing plates 263 will increase the friction force of the materials after the inertia is applied to the materials after contacting with the materials, the phenomenon of material being misplaced inside the claws 102 after the claws 102 swing left and right is avoided, thereby once again ensuring the stability of the grasped materials during movement.
[0043] like Figure 7 and Figure 8 As shown, a buffer component 3 is provided at the lower side of the arm 101 , and the buffer component 3 includes two fixing frames 31 fixedly connected to the lower side of the arm 101 .
[0044] The opposing surfaces of the two fixed frames 31 are provided with sliding grooves 32, and the two sliding grooves 32 are staggered. The insides of the two sliding grooves 32 are slidably connected with sliders 33. The opposing surfaces of the two fixed frames 31 and the two sliders 33 are fixedly connected with hinge seats 331. The opposing surfaces of the two hinge seats 331 are hinged with connecting rods 34, and the two connecting rods 34 are staggered. One side of the opposing surfaces of the two sliders 33 is clamped with a first magnetic block 35. A buffer cavity 37 is provided inside the fixed frame 31. The inside of the buffer cavity 37 is slidably connected with a piston block 36, and one side of the piston block 36 extends into the sliding groove 32. The first magnetic block 35 is slidably connected to the side of the piston block 36 close to the slider 33.
[0045] By adopting the above technical solution, firstly, during the operation of the arm 101, the two connecting rods 34 that are displaced and interlaced with each other will be pulled at the same time, and the other sides of the corresponding two connecting rods 34 are hinged to the outer side of the hinge seat 331 fixed by the opposite fixed frame 31. At this time, the connecting rod 34 will pull the hinge seat 331 fixed to the slider 33, and the slider 33 will slide inside the slide groove 32 after being pulled. Since the slider 33 is connected to the piston block 36 through the first magnetic block 35, the slider 33 will also drive the piston block 36 to move up and down inside the buffer chamber 37 during the process of moving up and down. When the piston block 36 is inside the buffer chamber 37, the piston block 36 will squeeze the air inside the buffer chamber 37. Since during the operation of the arm 101, the two sliders 33 will drive the piston block 36 to move in the corresponding reverse direction and squeeze the air inside the buffer chamber 37, so that the pressure on the arm 101 when the claw 102 is carrying materials is buffered, thereby alleviating the impact force on the connection between the claw 102 and the arm 101 due to inertia.
[0046] like Figure 8 As shown, a dust blowing assembly 38 is also provided inside the fixed frame 31, and the dust blowing assembly 38 includes baffles 381 respectively fixedly connected to the upper and lower sides of the piston block 36, and air outlets 382 are provided on the upper and lower sides of the fixed frame 31, and the two air outlets 382 are connected to the same buffer chamber 37, and the two baffles 381 are both slidably connected in the slide groove 32, and the connection between the buffer chamber 37 and the slide groove 32 is blocked during the movement of the baffles 381, and a movable groove 383 is provided on the side of the piston block 36 close to the slider 33, and the first magnetic block 35 is slidably connected in the movable groove 383, and a third return spring 384 is fixedly connected to the side of the movable groove 383 away from the slider 33, and the other end of the third return spring 384 is fixedly connected to the side of the first magnetic block 35 close to the third return spring 384.
[0047] By adopting the above technical scheme, first, during the movement of the piston block 36 inside the buffer chamber 37, the third return spring 384 inside the movable groove 383 on the side of the piston block 36 always pushes the first magnetic block 35 to make it enter the side of the slider 33, and the fixed baffle 381 of the piston block 36 will block the connection between the slide groove 32 and the buffer chamber 37. After the piston block 36 squeezes the air inside the buffer chamber 37, part of the air will be discharged through the air outlet 382 and blown to the joints between the arm 101 and the claw 102, and the arm 101 and the robot body 1, and the dust remaining at the joints will be blown out. Since part of the air flow will be blown to the joints between the arm 101 and the claw 102, and the arm 101 and the robot body 1 during the up and down movement of the piston block 36, the dust remaining at the joints between the arm 101 and the claw 102, and the arm 101 and the robot body 1 can be handled in time, thereby avoiding the wear of the arm 101 due to dust during operation.
[0048] like Figure 8 and Fig. 9 As shown, a liquid supply assembly 39 is disposed inside the fixed frame 31 , and the liquid supply assembly 39 includes two fixed cylinders 391 fixedly connected to the upper and lower sides of the fixed frame 31 .
[0049] A lifting rod 392 is slidably penetrated inside the two fixed cylinders 391, and the two lifting rods 392 are respectively located at the upper and lower sides of the piston block 36, and one end of the opposite surface of the two fixed cylinders 391 is fixedly connected to the second magnetic block 393, and the upper and lower sides of the piston block 36 are fixedly connected to the fourth return spring 394, and the ends of the two fourth return springs 394 that are far away are respectively fixedly connected to the upper and lower sides of the inside of the slide groove 32, and the two fourth return springs 394 are respectively sleeved on the outside of the two fixed cylinders 391, and a storage cavity 395 is opened inside the fixed frame 31, and the number of the storage cavity 395 is two, and the two storage cavities 395 are respectively located at the upper and lower sides of the slide groove 32. A through groove 396 is provided on one side of 395 close to the air outlet 382, and the two storage chambers 395 are respectively connected to the two air outlets 382 through the through groove 396. Anti-backflow membranes 397 are fixedly installed inside the two through grooves 396. Insertion grooves 398 are provided on the upper and lower sides of the piston block 36. After the piston block 36 moves, the insertion groove 398 is sleeved on one end of the fixed cylinder 391 fixed with the second magnetic block 393, and the insertion groove 398 is sleeved on the outer side of the second magnetic block 393. The second magnetic block 393 is inserted into the insertion groove 398 and magnetically adsorbed with the first magnetic block 35 inside the movable groove 383. After the first magnetic block 35 and the second magnetic block 393 are magnetically adsorbed, the first magnetic block 35 is separated from the slider 33.
[0050] By adopting the above technical solution, first, in the process of the slider 33 driving the piston block 36 to move up and down, the piston block 36 will squeeze the fourth return spring 394, and the lifting rod 392 in the fixed cylinder 391 will first enter the insertion groove 398 opened in the corresponding direction of the piston block 36. As the piston block 36 continues to move, the lifting rod 392 will also slide inside the fixed cylinder 391 and squeeze the lubricating liquid inside the storage chamber 395. Since an anti-backflow membrane 397 is provided inside the through groove 396, and the anti-backflow membrane 397 is an open rubber membrane that is closed for a long time at the center, it will deform after being compressed and a gap will appear. In a normal state, the pressure of the liquid is not enough to deform it, and it remains in a closed state. When the lubricant passes through the anti-backflow membrane 397 inside the through groove 396 and enters the air outlet 382, the airflow discharged from the buffer chamber 37 blows the lubricating liquid to the joint, and the fixed cylinder 391 is not After the second magnetic block 393 at the end enters the insertion groove 398, the second magnetic block 393 will absorb the first magnetic block 35 in the movable groove 383, so that the piston block 36 loses connection with the slider 33, and the piston block 36 is reset by the fourth reset spring 394, while the slider 33 continues to move. After the slider 33 moves in the opposite direction, because the edge of the slider 33 is arc-shaped, the slider 33 will squeeze the first magnetic block 35 and retract into the movable groove 383. After the two are re-docked, the first will enter the slider 33 again. At this time, the slider 33 will drive the piston block 36 to move in the opposite direction. During the process of the slider 33 driving the piston block 36 to move up and down, the lubricating fluid in the storage chamber 395 will be squeezed out in small doses and sprayed to the joint through the airflow pushed out by the piston block 36, which can not only reduce the heat generated by friction at the joint, but also facilitate the rapid removal of dust from the joint.
[0051] Working principle: First, when the robot body 1 controls the movement of the claw 102 through the arm 101, if the claw 102 swings in an up and down state, one of the magnet rods 23 inside the moving groove 21 in the claw 102 will collide with the inner wall of the moving groove 21, and the impact force generated will relieve the inertia generated by the material grabbed by the claw 102, and the other magnet rod 23 and the top rod 231 will enter the slot 251 on one side of the fixed seat 24 and be adsorbed inside the slot 251. At this time, the magnet rod 23 will push the moving rod 253 in the first limiting groove 252, so that the moving rod 253 slides inside the first limiting groove 252 through the guide block 254, and finally causes the two extrusion columns 255 to be on the moving rod 253. When the other magnet rod 23 enters the other side slot 251, the push rod 231 at the end of the magnet rod 23 will contact the push rod 231 at the end of the other magnet rod 23 and push the push rod 231. At this time, the first return spring 22 will pull the pushed magnet rod 23. When the moving rod 253 is pressing the pressing plate 263, the two pressing columns 255 will slide in the two second limiting grooves 261. Since the two pressing columns 255 are fixed to the pressing plate 263, the pressing columns 255 move downward to press the material. After the moving rod 253 is separated from the pressing column 255, the second return spring 262 in the second limiting groove 261 will lift the pressing column 255.
[0052] When the arm 101 is in motion, the two connecting rods 34 that are misaligned and interlaced with each other will be pulled at the same time, and the other sides of the corresponding two connecting rods 34 are hinged on the outer sides of the hinge seats 331 fixed by the opposite fixing frame 31. At this time, the connecting rods 34 will pull the fixed hinge seats 331 of the slider 33, and the slider 33 will slide inside the slide groove 32 after being pulled. Because the third return spring 384 inside the movable groove 383 on the side of the piston block 36 always pushes the first magnetic block 35 to make it enter the side of the slider 33, the slider 33 drives the piston block 36 to move up and down inside the buffer chamber 37 through the first magnetic block 35. When the piston block 36 is inside the buffer chamber 37, its internal airflow will be discharged through the air outlet 382 and blown to the joint. At the same time, the fixed baffle 381 of the piston block 36 will block the connection between the slide groove 32 and the buffer chamber 37. At the same time, the piston block 36 will squeeze the fourth return spring 394, and the fixed cylinder 39 The lifting rod 392 inside the piston block 36 will first enter the insertion groove 398 opened in the corresponding direction of the piston block 36, and squeeze the lubricating fluid inside the storage chamber 395. After the lubricating fluid passes through the anti-backflow membrane 397 inside the through groove 396 and enters the inside of the air outlet 382, the airflow discharged from the buffer chamber 37 blows the lubricating fluid to the joint. After the second magnetic block 393 at the end of the fixed cylinder 391 enters the insertion groove 398, the second magnetic block 393 will adsorb the first magnetic block 35 inside the movable groove 383, so that the piston block 36 loses connection with the slider 33. The piston block 36 is reset by the fourth reset spring 394, and the slider 33 continues to move. After the slider 33 moves in the opposite direction, because the edge of the slider 33 is arc-shaped, the slider 33 will squeeze the first magnetic block 35 and shrink into the inside of the movable groove 383. After the two are re-connected, the first magnetic block 35 will enter the slider 33 again, and finally the slider 33 will drive the piston block 36 to move in the opposite direction.
