Description

Technical Field

[0001] The present invention relates to the technical field of industrial robots, and in particular to an industrial robot with a lightweight and high-strength joint assembly and a method for using the same. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and relies on its own power and control capabilities to achieve various functions. It can accept human commands or run according to pre-programmed programs. Modern industrial robots can also act according to the principles and guidelines formulated by artificial intelligence technology. In industrial production, industrial robots can replace people to do certain monotonous, frequent and repetitive long-term operations, or operations in dangerous and harsh environments, such as in stamping, pressure casting, heat treatment, welding, painting, plastic product forming, machining and simple assembly processes, as well as in the atomic energy industry and other departments, to complete the handling or process operations of materials that are harmful to the human body.

[0004] When the above patent is in use, by setting a sensor inside the grasping claw, simple data analysis and processing can be performed on the grasped objects, thereby increasing its functionality and ensuring the safety of the transported objects. Since some products are thin-walled shell parts during aluminum alloy stamping and casting, the mechanical claw will deform the thin-walled shell parts when clamping the parts.

[0008] As a further solution of the present invention, a baffle is fixedly mounted on the outer surface of the sliding column near one end of the top head, and a first spring is sleeved on the outer surface of the sliding column, and the first spring is arranged between the baffle and the mounting plate.

[0009] As a further solution of the present invention, a guide column is fixedly installed on the other end of the sliding column, and a seesaw is rotatably installed between the inner walls of the clamping jaws. A waist-shaped groove is penetrated through the outer surface of the seesaw near one end of the sliding column, and the other end of the sliding column penetrates the waist-shaped groove, and the seesaw is arranged between the guide column and the mounting plate.

[0010] As a further solution of the present invention, a first driven gear is rotatably installed between the inner walls of the clamping jaws, the first driven gear is arranged at the end of the seesaw away from the sliding column, a cam is fixedly installed on the outer surface of the rotation center of the first driven gear, the cam is abutted against the outer surface of the seesaw, a driving gear is fixedly installed on the outer surface of the rotating shaft, the driving gear is meshed with the first driven gear, a second spring is fixedly installed on the outer surface of the seesaw close to the cam, and the other end of the second spring is fixedly connected to the inner wall of the clamping jaws.

[0011] As a further solution of the present invention, an indicator sign is rotatably installed between the inner walls of the clamp, and a second driven gear is fixedly installed at both ends of the indicator sign.

[0014] A method for using a lightweight and high-strength joint component industrial robot comprises the following steps:

[0015] S1: The operator sets the clamping jaws to clamp the aluminum alloy shell from the top through programming. When the clamping jaws are in the loose state, the raised surface of the cam abuts against the seesaw, causing the other end of the seesaw to tilt and move. The seesaw restricts the sliding of the slide post through the guide post. At this time, the slide post restricts the head to be flush with the clamping surface of the clamping jaws;

[0016] S2: When the two clamps are close to each other, they will clamp the housing part. When the two clamps move close to each other, they will drive the shaft to rotate. The shaft drives the cam to rotate through the driving gear and the first driven gear, so that the convex surface of the cam is away from the rocker. The other end of the rocker is away from the guide column through the second spring and does not contact the guide column.

[0017] S3: The slide column drives the ejector head to abut against the surface of the shell part through the first spring. When the surface of the shell part is subjected to a large clamping force, the thin wall of the shell will be deformed and bent. At this time, the ejector head will move away from the seesaw plate and protrude from the clamping surface of the clamping claw.

[0018] S4: The guide post is driven by the sliding post to move in the direction close to the top head, the guide post drives the rotating plate to rotate through the guide groove, the rotating plate drives the second driven gear to rotate through the fan gear, and the second driven gear drives the sign to rotate. When the flip angle of the sign is greater than 90°, the operator can intuitively see the prompt of the sign.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the thin wall of the shell is deformed greatly, the guide column is driven by the sliding column to move in the direction close to the top head, the guide column drives the rotating plate to rotate through the guide groove, the rotating plate drives the second driven gear to rotate through the fan gear, and the second driven gear drives the indicator to rotate. When the indicator flips at an angle greater than 90°, the operator can intuitively see the prompt of the indicator. At this time, the operator can judge that the clamping force of the shell parts is too large, and can adjust the clamping force of the drive motor in time. Through this device, the operator can intuitively see whether the clamping claws have deformed the shell parts in time, avoiding excessive clamping force that causes batch deformation and scrapping of products;

[0021] 2. The mechanical joints of the industrial robot body are composed of lightweight and high-strength joints, which improve the flexibility, efficiency and load capacity of the robot's movement, while reducing energy consumption and improving the reliability of the robot.

The other end of the sliding column 14 is fixedly installed with a guide column 25, and a seesaw 17 is rotatably installed between the inner walls of the clamping jaws 3. The outer surface of the seesaw 17 near the end of the sliding column 14 is penetrated with a waist groove 27, and the other side of the sliding column 14 is penetrated with the waist groove 27. The seesaw 17 is arranged between the guide column 25 and the mounting plate 13, and the clamping jaws 3 A first driven gear 20 is rotatably mounted between the inner walls of the seesaw 17. The first driven gear 20 is arranged at the end of the seesaw 17 away from the sliding column 14. A cam 21 is fixedly mounted on the outer surface of the rotation center of the first driven gear 20. The cam 21 abuts against the outer surface of the seesaw 17. A driving gear 19 is fixedly mounted on the outer surface of the rotating shaft 28. The driving gear 19 meshes with the first driven gear 20. A second spring 18 is fixedly mounted on the outer surface of the seesaw 17 close to the cam 21. The other end of the second spring 18 is fixedly connected to the inner wall of the clamp 3.

[0034] When the two clamping jaws 3 move toward each other, the rotating shaft 28 will be driven to rotate. The rotating shaft 28 drives the cam 21 to rotate through the driving gear 19 and the first driven gear 20, so that the raised surface of the cam 21 is away from the seesaw 17. The seesaw 17 is made to move away from the guide column 25 at the other end through the second spring 18 and does not contact the guide column 25. At this time, the sliding column 14 drives the head 11 to resist the surface of the shell part through the first spring 16. When the surface of the shell part is subjected to a large clamping force, the thin wall of the shell will be deformed and bent. At this time, the head 11 will move away from the seesaw 17, and the head 11 will protrude from the clamping surface of the clamping jaw 3. Through this device, the operator can see in time and intuitively whether the clamping jaw 3 has deformed the shell part, thereby avoiding the deformation and scrapping of batches of products due to excessive clamping force.

[0035] In this embodiment, an indicator sign 12 is rotatably installed between the inner walls of the clamping jaws 3, and a second driven gear 22 is fixedly installed at both ends of the indicator sign 12. Fan gears 23 are rotatably installed on the inner walls of the opposite sides of the clamping jaws 3, and the fan gear 23 is meshed with the second driven gear 22. A rotating plate 26 is fixedly installed on the outer surface of the fan gear 23, and a guide groove 24 is penetrated through the outer surface of the rotating plate 26 close to the end of the sliding column 14, and the guide column 25 is slidably installed with the inner wall of the guide groove 24. A driving motor 4 is fixedly installed on the top of the mounting frame 2, and a lead screw 6 is fixedly installed on the output end of the driving motor 4 through the outer surface of the mounting frame 2, and a driving rod 5 is threadedly connected to the outer surface of the lead screw 6. A connecting rod 9 is rotatably installed on the inner walls of the driving rod 5 close to both ends, and the other end of the connecting rod 9 is rotatably connected to the other end of the L-shaped rotating rod 7, and a parallelogram structure is formed through the connecting rod 8 and the L-shaped rotating rod 7.

[0036] The screw rod 6 is driven to rotate by the driving motor 4, and the screw rod 6 drives the driving rod 5 to move away from the clamping jaw 3. The driving rod 5 drives the L-shaped rotating rod 7 to move closer to each other through the connecting rod 9. The L-shaped rotating rod 7 drives the two clamping jaws 3 to move closer to each other through the connecting rod 8. When the two clamping jaws 3 are close to each other, they will clamp the shell parts. When the thin wall deformation of the shell is large, the guide column 25 is driven by the sliding column 14 to move in the direction close to the top head 11. The guide column 25 drives the rotating plate 26 to rotate through the guide groove 24. The rotating plate 26 drives the second driven gear 22 to rotate through the fan gear 23. The second driven gear 22 drives the indicator board 12 to rotate. When the flip angle of the indicator board 12 is greater than 90°, the operator can intuitively see the prompt of the indicator board 12.

[0037] In this embodiment, the mechanical joints of the industrial robot body 1 are composed of lightweight and high-strength joints. The lightweight and high-strength joints improve the flexibility, efficiency and load capacity of the robot's movement, while reducing energy consumption and improving the reliability of the robot. The clamping surface of the clamp 3 is provided with a rubber pad to prevent slipping when placing the clamped shell parts. The clamp 3 in this device is suitable for clamping shell parts of the same clamping size.

[0038] A method for using a lightweight and high-strength joint component industrial robot comprises the following steps:

[0039] S1: The operator sets the clamping jaw 3 to clamp the aluminum alloy shell from above through programming. When the clamping jaw 3 is in the loose state, the convex surface of the cam 21 abuts against the seesaw 17, so that the other end of the seesaw 17 tilts up, and the seesaw 17 restricts the sliding of the slide post 14 through the guide post 25. At this time, the slide post 14 restricts the head 11 to be flush with the clamping surface of the clamping jaw 3;

[0040] S2: When the two clamping jaws 3 are close to each other, they will clamp the housing part. When the two clamping jaws 3 move towards each other, they will drive the rotating shaft 28 to rotate. The rotating shaft 28 drives the cam 21 to rotate through the driving gear 19 and the first driven gear 20, so that the convex surface of the cam 21 is away from the rocker 17. The other end of the rocker 17 is away from the guide column 25 through the second spring 18 and does not contact the guide column 25.

[0041] S3: The slide column 14 drives the plug 11 to abut against the surface of the shell part through the first spring 16. When the surface of the shell part is subjected to a large clamping force, the thin wall of the shell will be deformed and bent. At this time, the plug 11 will move away from the rocker 17 and protrude from the clamping surface of the clamping jaw 3.

[0042] S4: The guide post 25 is driven by the slide post 14 to move in the direction close to the top head 11, the guide post 25 drives the rotating plate 26 to rotate through the guide groove 24, the rotating plate 26 drives the second driven gear 22 to rotate through the fan gear 23, and the second driven gear 22 drives the indicator board 12 to rotate. When the flip angle of the indicator board 12 is greater than 90°, the operator can intuitively see the prompt of the indicator board 12.

[0043] It should be noted that when the present invention is in use, the operator sets the clamping jaw 3 to clamp the aluminum alloy shell from above through programming. When the clamping jaw 3 is in a loose state, the convex surface of the cam 21 abuts against the seesaw 17, so that the other end of the seesaw 17 tilts up, and the seesaw 17 restricts the sliding of the slide post 14 through the guide post 25. At this time, the slide post 14 restricts the head 11 from being flush with the clamping surface of the clamping jaw 3. When the clamping jaw 3 clamps the shell part, the lead screw 6 is driven to rotate by the driving motor 4, and the lead screw 6 drives the driving rod 5 away from the housing. The clamping jaws 3 move, the driving rod 5 drives the L-shaped rotating rod 7 to move closer to each other through the connecting rod 9, and the L-shaped rotating rod 7 drives the two clamping jaws 3 to move closer to each other through the connecting rod 8. When the two clamping jaws 3 move closer to each other, they will clamp the shell parts. When the two clamping jaws 3 move closer to each other, they will drive the rotating shaft 28 to rotate. The rotating shaft 28 drives the cam 21 to rotate through the driving gear 19 and the first driven gear 20, so that the convex surface of the cam 21 is away from the rocker 17, and the rocker 17 is moved away from the guide column 25 at the other end by the second spring 18. , does not contact with the guide column 25. At this time, the slide column 14 drives the head 11 to resist the surface of the shell part through the first spring 16. When the surface of the shell part is subjected to a large clamping force, the thin wall of the shell will be deformed and bent. At this time, the head 11 will move away from the rocker 17, and the head 11 will protrude from the clamping surface of the clamping claw 3. When the thin wall of the shell is greatly deformed, the slide column 14 drives the guide column 25 to move in the direction close to the head 11. The guide column 25 drives the rotating plate 26 to rotate through the guide groove 24. The rotating plate 26 drives the second driven gear 22 to rotate through the fan gear 23. The second driven gear 22 drives the indicator board 12 to rotate. When the flip angle of the indicator board 12 is greater than 90°, the operator can intuitively see the prompt of the indicator board 12. At this time, the operator can judge that the clamping force of the shell part is too large, and can adjust the clamping force of the drive motor 4 in time. Through this device, it is convenient for the operator to timely and intuitively see whether the clamping claw 3 has deformed the shell part, thereby avoiding excessive clamping force causing batch deformation and scrapping of products.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.

At this time, the push head (11) will move away from the seesaw (17) and the push head (11) will protrude from the clamping surface of the clamping claw (3); S4: The guide post (25) is driven by the slide post (14) to move in a direction close to the top head (11), the guide post (25) drives the rotating plate (26) to rotate through the guide groove (24), the rotating plate (26) drives the second driven gear (22) to rotate through the fan gear (23), and the second driven gear (22) drives the indicator board (12) to rotate. When the flip angle of the indicator board (12) is greater than 90°, the operator can intuitively see the prompt of the indicator board (12).
