Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to a self-lubricating gantry robot. Background Technology

[0002] A truss robot is an automated material handling device based on a truss structure. It consists of a frame composed of beams and columns, and moves in three-dimensional space by a slider and a robotic arm driven by a servo motor to complete tasks such as material handling, assembly, and loading / unloading. It features high speed, high precision, and high load capacity.

[0003] Lubrication gantry robots can reduce maintenance needs, avoid frequent downtime for lubrication, and are suitable for complex environments with high dust and oil sensitivity. They prevent lubricant from contaminating workpieces, reduce friction loss, extend component life, and ensure long-term operational accuracy and stability. In automated production lines, they can improve continuous operation efficiency and reduce manual maintenance costs.

[0004] During gantry robot operations, the handling machine can only move up and down, limiting its range of motion and making it difficult to grasp objects at different horizontal positions, affecting the flexibility and coverage of the operation.

However, in actual use, the moving track will wear down due to long-term friction, resulting in a decrease in the accuracy of the track surface and a reduction in the positioning accuracy during movement, affecting the accuracy of grasping.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a self-lubricating gantry robot, comprising a support 1 and a movable seat 2. The support 1 is provided with a moving mechanism 4 on both the top left and right sides. The moving mechanism 4 is used to move the movable seat 2 in a horizontal position.

[0034] The lubrication mechanism 3 includes two oil tanks 31. The bottoms of the two oil tanks 31 are located on the top left and right sides of the moving mechanism 4. Oil pumps 32 are fixedly connected to the outside of the two oil tanks 31. Oil pipes 33 are fixedly connected to the bottom of the two oil pumps 32.

[0035] Specifically, when the lubrication mechanism 3 is working, two oil tanks 31 store lubricating medium and are located on the top left and right sides of the moving mechanism 4 to provide a medium source for lubrication operations. Through the cooperation of the oil tanks 31 and the moving mechanism 4, the lubricating medium is supplied in a follow-up manner.

[0036] When the oil pump 32 on the outside of the oil tank 31 is started, the lubricating medium inside the oil tank 31 is extracted and transported through the oil pipe 33 to the nozzles 34 on the left and right sides of the front of the moving mechanism 4. The nozzles 34 spray the lubricating medium onto the top of the longitudinal guide rail 41. Through the cooperation of the oil pump 32 and the oil pipe 33, the directional delivery and spraying of the lubricating medium is realized.

[0037] The oil tank 2 35 on the rear side of the top of the movable seat 2 also stores the lubricating medium. After the oil pump 2 36 on the front side is started, the lubricating medium in the oil tank 2 35 is extracted and transported to the nozzle 2 38 on the right side of the movable seat 2 through the oil pipe 2 37. The nozzle 2 38 sprays the lubricating medium onto the top of the transverse guide rail 44. Through the cooperation of the oil pump 2 36 and the oil pipe 2 37, the lubricating medium is transported and sprayed.

[0038] In the control assembly 39 at the top of the mobile base 2, the electrical cabinet 391 controls the operation of oil pump 1 32 and oil pump 2 36. The cabinet door 392 is rotatably connected to the front of the electrical cabinet 391 and can be opened for operation and maintenance. Through the cooperation of the electrical cabinet 391 and the cabinet door 392, the control and maintenance of the lubrication mechanism 3 can be made convenient.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The moving mechanism 4 includes two longitudinal guide rails 41. The bottom of the two longitudinal guide rails 41 is fixedly connected to the top left and right sides of the bracket 1, respectively. Multiple longitudinal sliders 42 are slidably connected to the top of each of the two longitudinal guide rails 41.

A transverse guide rail 44 is fixedly connected to the front and rear sides of the top of the cross frame 43. Multiple transverse sliders 45 are slidably connected to the top of each of the two transverse guide rails 44.

[0040] The top left and right sides of the cross frame 43 are provided with longitudinal drive components 46. The longitudinal drive components 46 include two servo motors 461. The bottom of the two servo motors 461 is fixedly connected to the top left and right sides of the cross frame 43 respectively. The bottom of the two servo motors 461 is fixedly connected with gears 462. The bottom left and right sides of the cross frame 43 are provided with longitudinal displacement components 47. The longitudinal displacement components 47 include two racks 471. The bottom of the two racks 471 is fixedly connected to the top left and right sides of the bracket 1 respectively. The bottom left and right sides of the cross frame 43 are fixedly connected with balance gears 472.

[0041] The top of the movable seat 2 is provided with a transverse drive assembly 48, which includes a second servo motor 481. The bottom of the second servo motor 481 is fixedly connected to the top of the movable seat 2. The bottom of the second servo motor 481 is fixedly connected with a second gear 482. The bottom of the movable seat 2 is provided with a transverse displacement assembly 49, which includes a second rack 491. The front side of the second rack 491 is fixedly connected to the top front side of the cross frame 43. The bottom of the movable seat 2 is fixedly connected with a second balance gear 492. The top of the two longitudinal guide rails 41 is provided with a limit assembly 410. The limit assembly 410 includes multiple limit blocks 4101. The outer side of each of the multiple limit blocks 4101 is fixedly connected with a buffer pad 4102.

[0042] Specifically, when the moving mechanism 4 is working, the longitudinal guide rail 41 is fixed to the top of the bracket 1, the longitudinal slider 42 slides on the top, driving the cross frame 43 to move longitudinally, the transverse guide rail 44 moves with the cross frame 43, and the transverse slider 45 slides on the top of the transverse guide rail 44, driving the moving seat 2 to move transversely. Through the cooperation of the longitudinal guide rail 41 and the longitudinal slider 42, and the transverse guide rail 44 and the transverse slider 45, the longitudinal and transverse movement guidance of the moving seat 2 is realized.

[0043] In the longitudinal drive assembly 46, the servo motor 461 starts and drives the gear 462 to rotate. The gear 462 meshes with the rack 471 of the longitudinal displacement assembly 47. The balance gear 472 assists the gear 462 to maintain stable meshing. Through the cooperation of the gear 462 and the rack 471, the crossbeam 43 is driven to move along the longitudinal guide rail 41.

[0044] In the transverse drive assembly 48, the servo motor 481 starts and drives the gear 482 to rotate. The gear 482 meshes with the rack 491 of the transverse displacement assembly 49. The balancing gear 492 assists the gear 482 to maintain stable meshing. Through the cooperation between the gear 482 and the rack 491, the moving seat 2 is driven to move along the transverse guide rail 44.

[0045] In the limiting assembly 410 at the top of the longitudinal guide rail 41, the limiting block 4101 restricts the movement range of the longitudinal slider 42, and the buffer pad 4102 reduces the impact when the longitudinal slider 42 contacts the limiting block 4101. Through the cooperation of the limiting block 4101 and the buffer pad 4102, the longitudinal movement is limited and buffered.

[0046] Working principle: The moving mechanism 4 is operated. The electrical cabinet 391 of the control component 39 at the top of the moving seat 2 sends a command to start the servo motor 461 of the longitudinal drive component 46. The rotation of the servo motor 461 drives the gear 462 at the bottom to rotate synchronously. The gear 462 meshes with the rack 471 of the longitudinal displacement component 47. The balance tooth 472 at the bottom of the cross frame 43 is in contact with the rack 471. The auxiliary gear 462 maintains a stable meshing state to avoid loosening and deviation. Under the transmission action of the gear and rack, multiple longitudinal sliders 42 at the bottom of the cross frame 43 slide along the top of the longitudinal guide rail 41, driving the cross frame 43 to move in the longitudinal direction. When the longitudinal slider 42 moves to the limit block 4101 at the top of the longitudinal guide rail 41, the limit block 4101 blocks the longitudinal slider 42 from moving further. The outer buffer pad 4102 contacts the longitudinal slider 42 to reduce the impact force generated by the collision between the two and complete the adjustment of the longitudinal position.

[0047] The electrical cabinet 391 controls the start of the servo motor 481 of the transverse drive component 48. The rotation of the servo motor 481 drives the gear 482 at the bottom to rotate synchronously. The gear 482 meshes with the rack 491 of the transverse displacement component 49. The balance gear 492 at the bottom of the moving seat 2 is in contact with the rack 491. The auxiliary gear 482 maintains stable meshing. Under the transmission action, multiple transverse sliders 45 at the bottom of the moving seat 2 slide along the transverse guide rail 44 at the top of the cross frame 43, driving the moving seat 2 to move in the transverse direction and complete the adjustment of the transverse position.

[0048] During the operation of the moving mechanism 4, the lubrication mechanism 3 is started simultaneously. The electrical cabinet 391 controls the operation of the oil pump 32 outside the oil tank 31. The oil pump 32 extracts the lubricating medium stored in the oil tank 31 and delivers it to the nozzles 34 at the left and right ends of the front side of the moving mechanism 4 through the oil pipe 33. The nozzles 34 spray the lubricating medium evenly onto the top of the longitudinal guide rail 41 to lubricate the contact part between the longitudinal guide rail 41 and the longitudinal slider 42.

[0049] Electrical cabinet 391 controls the operation of oil pump 2 36 on the front side of oil tank 2 35. Oil pump 2 36 extracts the lubricating medium from oil tank 2 35 and delivers it to nozzle 2 38 on the right side of moving seat 2 via oil pipe 2 37. Nozzle 2 38 sprays the lubricating medium evenly onto the top of transverse guide rail 44 to lubricate the contact part between transverse guide rail 44 and transverse slider 45, reducing frictional resistance during movement.

[0050] When equipment maintenance is required, turn the cabinet door 392 on the front side of the electrical cabinet 391 to open it, and then you can check, debug and replace the components inside the electrical cabinet 391.
