Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and in particular to a transfer manipulator for industrial automation. Background Art

[0002] In the field of automobile manufacturing, the efficient operation of automobile assembly lines is crucial to improving automobile production efficiency and quality. As an important equipment on automobile assembly lines, transfer manipulators undertake the key tasks of grabbing, transporting and assembling various automobile parts.

[0003] At present, common transfer robots usually use suction cups to grab auto parts. However, during the transfer process, the suction cups are prone to weakening their adsorption force on the surface of the parts, which may cause the parts to fall and seriously affect the transfer efficiency of auto parts.

[0004] There are many existing technologies for transfer manipulators, such as:

[0005] Chinese patent publication number CN218707024U discloses a transfer robot for automobile assembly production line, which includes a mounting base, an outer shell, a vertical pole and an adsorption structure. A clamping structure is also arranged on one side of the vertical pole. The clamping structure includes a bottom groove and a threaded rod arranged inside the bottom groove. One end of the threaded rod is connected to the output end of the micro motor. The outer thread of the threaded rod is sleeved with a movable block. A cylinder part is installed at the lower end of the movable block. A clamping plate is installed at the lower end of the cylinder part. The utility model solves the problem that the suction force of the suction cup on the surface of the accessory is easily weakened during the transfer process, which may cause the accessory to fall, thereby affecting the transfer efficiency of the automobile accessories. Through the provided suction cup, suction pipe, exhaust pipe, telescopic pipe, cylinder part, clamping plate, micro motor, threaded rod and movable block, the suction cup can be adsorbed on the accessory, and the clamping effect on the accessory can be enhanced in combination with the clamping plate, and the anti-falling effect is good.

[0006] It can be seen that most transfer robots will clamp both sides of the auto parts after adsorbing them to achieve the stability of the auto parts during transportation. However, in the production and transportation process of auto parts, due to the differences in size and weight of auto parts, when considering the use of two-side clamping to fix the accessories for transportation, for heavier accessories, the clamping structure may be under greater pressure due to the excessive weight of the accessories themselves. In this case, it is easy to reduce the actual effect of the side clamp and reduce the stability of the clamping. Once the clamping is unstable, the accessories may fall off due to the unstable suction cup during transportation, which will not only affect the production efficiency of the auto parts transportation work, but may also cause damage to the accessories, increase production costs, and thus reduce the safety of the use of the transfer robot.

[0007] In view of this, we propose a transfer robot for industrial automation. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] See also Figure 1-Figure 4 As shown, the present embodiment aims to provide a transfer robot for industrial automation, including a body 10, a moving plate 11, a top plate 12, a bottom plate 13 and a suction cup machine 14. The positions of the body 10, the moving plate 11, the top plate 12, the bottom plate 13 and the suction cup machine 14 are arranged by Figure 1 and Figure 2It can be seen that a hydraulic cylinder 20 is provided on the side of the movable plate 11 away from the machine body 10, and the hydraulic cylinder 20 is located on the upper surface of the bottom plate 13, an auxiliary member 21 is provided at the end of the piston rod inside the hydraulic cylinder 20, a support member 22 is provided above the auxiliary member 21 and close to the hydraulic cylinder 20, and lifting members 23 are provided on both sides of the side above the auxiliary member 21 away from the support member 22, and a backing member 30 is provided on the upper surface of the lifting member 23;

[0035] The support member 22 is used to assist the hydraulic cylinder 20 in moving the position of the auxiliary member 21, and also supports the auxiliary member 21 to increase the stability of the position movement of the auxiliary member 21. The auxiliary member 21 can support the bottom of the auto parts to prevent the auto parts from falling. The lifting member 23 is used to adjust the height of the guide member 34, which is suitable for auto parts of different thicknesses. The guide member 34 can guide the auxiliary member 21 to enter the bottom of the suction cup machine 14. At the same time, the auto parts are clamped by the rebound force of the guide member 34 and the distance between the suction cup machine 14.

[0036] Since auto parts have various sizes, including different lengths or widths, when transferring them, a transfer robot corresponding to the size is required, which reduces the flexibility of the transfer robot and increases the cost of auto parts production. Therefore, according to Figure 1-Figure 5 As shown, the specific structure of the auxiliary component 21 is disclosed. The auxiliary component 21 at least includes a mounting block 211. A two-way cylinder 212 is arranged inside the mounting block 211. The piston rods at both ends of the two-way cylinder 212 are provided with adjustment blocks 213. A mounting plate 214 is arranged below the adjustment block 213.

[0037] The two-way cylinder 212 is powered on to start working, and the piston rods at both ends of the two-way cylinder 212 push the two adjustment blocks 213 away from each other, so that the distance between the two mounting plates 214 is increased. Similarly, when the piston rods at both ends of the two-way cylinder 212 are reset, the distance between the two mounting plates 214 is shortened, thereby improving the flexibility of the auxiliary part 21 and being able to adapt to the transportation needs of auto parts of different sizes, reducing the need to equip a variety of transportation robots due to the variety of sizes of parts, thereby reducing the cost of auto parts production. At the same time, the control of the two-way cylinder 212 can ensure that the distance adjustment between the mounting plates 214 is accurate and reliable, thereby improving the stability and efficiency of the transportation process, thereby reducing the cost of auto parts transportation.

[0038] Considering that the auxiliary member 21, the lifting member 23 and the backing member 30 have weight during the pushing process of the hydraulic cylinder 20, in order to reduce the pressure of the hydraulic cylinder 20, reduce the stability of the movement of the auxiliary member 21, the lifting member 23 and the backing member 30, and increase the risk of using the transfer robot, therefore, according to Figure 1 , Figure 2 and Figure 4 As shown, the specific structure of the support member 22 is disclosed. The support member 22 at least includes a support column 221, and the support column 221 is located on the upper surface of the mounting block 211. A slider 222 is provided at one end of the support column 221 away from the mounting block 211, and a slide rail 223 for sliding connection with the slider 222 is provided in the middle of the lower surface of the top plate 12.

[0039] When the piston rod inside the hydraulic cylinder 20 is pushing or resetting, the slider 222 is in a sliding state inside the slide rail 223 and is connected to the mounting block 211 through the support column 221. This can not only reduce the pushing pressure of the hydraulic cylinder 20, but also reduce the stability risk of the movement of the auxiliary parts 21, the lifting parts 23 and the supporting parts 30, and increase the safety of the use of the transfer robot. At the same time, it makes the entire transfer process smoother and improves the efficiency of the transfer. The existence of the support part 22 provides reliable support and guidance for the various components of the transfer robot, ensuring the accurate position and stable posture of the auto parts during the transfer process, and further improving the quality and reliability of the auto parts production.

[0040] In order to make the transfer robot suitable for automobile parts of different thicknesses and reduce the probability of damage to the suction cup machine 14, Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the specific structure of the lifting member 23 is disclosed. The lifting member 23 at least includes an electric telescopic rod 231. The electric telescopic rod 231 is located inside the upper surface of the mounting plate 214. A lifting plate 232 is provided at the end of the piston rod inside the electric telescopic rod 231.

[0041] By turning on the electric telescopic rod 231 and pushing or resetting the piston rod inside the electric telescopic rod 231, the lifting plate 232 is driven to move up and down, and the position of the supporting part 30 can be adjusted, so that the transfer robot can be suitable for auto parts of different thicknesses, which can improve the versatility and adaptability of the transfer robot. When facing auto parts of various specifications, there is no need to frequently replace different transfer equipment, which greatly improves production efficiency. At the same time, the lifting adjustment can ensure the stability of auto parts during the transfer process, avoid shaking or falling due to height mismatch, and further improve the quality of auto parts and production safety.

[0042] Since the bottom of the auto parts needs to be supported, in order to enable the liner 30 to quickly move to the bottom of the auto parts and form a clamping state with the suction cup machine 14 to increase the stability of the auto parts transportation, therefore, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6and Figure 7 As shown, the specific structure of the supporting member 30 is disclosed. The supporting member 30 at least includes an elastic member 31. The lower end of the elastic member 31 is fixedly connected to the upper surface of the lifting plate 232. The upper end of the elastic member 31 is provided with a support plate 32. The support plate 32 is provided with a guide plate 344 for moving away from the mounting block 211. The lower end of the guide plate 344 is slidably connected to the upper surface of the mounting plate 214 through a limit member 35. The upper surface of the mounting plate 214 is provided with an elastic frame 33, and the elastic frame 33 is a right-angled trapezoid.

[0043] according to Figure 8 As shown, the guide member 34 at least includes a first connecting block 341, a second connecting block 342 and a guide plate 344. The upper surface of the first connecting block 341 is fixedly connected to one end of the lower surface of the support plate 32 away from the mounting block 211, and the second connecting block 342 is located above the limit member 35. A connecting shaft 343 is provided on both sides of the first connecting block 341 and the second connecting block 342. The other end of the connecting shaft 343 is rotatably connected to the inside of the guide plate 344. A return spring 345 is provided on the outside of the connecting shaft 343. The two ends of the return spring 345 are respectively fixedly connected to the guide plate 344 and the first connecting block 341 and the second connecting block 342.

[0044] The limiting member 35 at least includes a limiting block 351, the upper surface of which is fixedly connected to the lower surface of the second connecting block 342, and a limiting groove 352 is formed on the upper surface of the mounting plate 214 away from the lifting plate 232 and the mounting block 211, and the limiting groove 352 is slidably connected to the limiting block 351.

[0045] When the hydraulic cylinder 20 moves the auxiliary part 21 to the bottom of the suction cup machine 14, the inclined surface of the elastic frame 33 contacts the bottom of the automobile part, causing the elastic part 31 to deform and shrink, and the elastic frame 33 is also deformed accordingly, and the guide plate 344 slides inside the limiting groove 352 through the limiting block 351, increasing the inclination angle of the guide plate 344. At the same time, the return spring 345 is also deformed accordingly. The auxiliary support plate 32 is located below the automobile part, and the automobile part is clamped by the rebound force of the elastic part 31 and the distance between the suction cup machine 14, which can improve the stability of the automobile part during transportation and ensure that the automobile part will not shake or fall easily during movement. The cooperation between the elastic frame 33 and the elastic part 31 can adapt to automobiles of different sizes and shapes. Accessories, increase the versatility of the transfer robot, the design of the guide plate 344 and the limiter 35 makes the structure of the support member 30 more flexible and can be adjusted according to actual conditions, thereby improving the convenience and efficiency of operation. In addition, during the transfer of automobile accessories, when encountering bumps or external force impacts, the elastic member 31 can play a buffering role, reduce the vibration of the automobile accessories, and protect the automobile accessories from damage. At the same time, the tiltable design of the guide plate 344 and the setting of the return spring 345 enable the support member 30 to better adapt to automobile accessories of different shapes and sizes, thereby improving the versatility and flexibility of the transfer robot, and the setting of the limiter 35 improves the stability of the guide plate 344 during movement, thereby further enhancing the stability of the transfer of automobile accessories.

[0046] In summary, the working principle of this scheme is as follows: first, open the machine body 10, adjust the position of the moving plate 11, and then move the position of the suction cup machine 14 so that it is located above the auto parts, and turn on the suction cup machine 14 to adsorb the auto parts. Next, connect the power supply of the two-way cylinder 212 to make it work, and push the piston rods at both ends of the two-way cylinder 212 to drive the two adjustment blocks 213 away from each other, so that the distance between the two mounting plates 214 is increased to accommodate large-sized accessories, or reset to reduce the distance between the two mounting plates 214 to accommodate small-sized accessories. Then, according to the thickness of the auto parts, turn on the electric telescopic rod 231, adjust the height of the lifting plate 232, and then adjust the position of the lining member 30, so that the transfer robot can be suitable for auto parts of different thicknesses.

[0047] Then, the hydraulic cylinder 20 is started to push the auxiliary part 21 to move under the suction cup machine 14. During the movement, the slider 222 of the support part 22 slides in the slide rail 223 on the lower surface of the top plate 12 to provide support for the movement of the auxiliary part 21, the lifting part 23 and the backing part 30. When the auxiliary part 21 approaches the bottom of the suction cup machine 14, the inclined surface of the elastic frame 33 first contacts the bottom of the automobile part, causing the elastic part 31 to deform and shrink, and the elastic frame 33 also deforms accordingly. At the same time, the guide plate 344 slides in the limiting groove 352 through the limiting block 351, increasing the guide plate At the tilted angle of 344, the reset spring 345 is also deformed. With the continuous movement of the auxiliary part 21, the support plate 32 is located below the auto part with the assistance of the guide plate 344, so that the rebound force of the elastic part 31 and the distance between the suction cup machine 14 clamp the auto part. At this time, the auto part is transferred. Similarly, when the piston rod inside the hydraulic cylinder 20 is reset, it drives the supporting part 30 away from the auto part, and then operates the suction cup machine 14 to place the auto part at the designated position, thus completing the transfer of the auto part by the transfer robot.
