Description

Technical Field

[0001] The present invention relates to the field of robot technology, in particular to a quantum intelligent industrial robot protection mechanism. Background Art

[0002] Quantum intelligent welding robot is an industrial robot engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization, industrial robots belong to standard welding robots. Industrial robots are multi-purpose, reprogrammable automatic control manipulators with three or more programmable axes. The core of the robot's multi-axis motion controller is usually the motion control algorithm, which can calculate the motion parameters of each axis, such as speed, acceleration, distance, etc., according to the user's instructions.

[0003] The invention patent with patent number CN112621045B discloses a base, a first turntable at the top of the base, a first mechanical arm connected to the first turntable, a second turntable connected to the other end of the first mechanical arm, and a second mechanical arm connected to the second turntable, the other end of the second mechanical arm is equipped with a working head, the top of the base is also equipped with a first gas storage mechanism for providing fire extinguishing gas, the first gas storage mechanism is connected to a pipeline mechanism for gas transmission, and the second mechanical arm is equipped with a protective component connected to the pipeline mechanism. The present invention enables the fire extinguishing gas to pass through the path passed by the welding gas during the transmission process, and completes the protection of the pipeline system part during the transmission process, improves the safety of the pipeline system part when an open flame occurs, improves the overall safety, and prolongs the service life.

[0004] The above-mentioned device protects the pipeline system by transmitting the fire-extinguishing gas along the pipeline components, thereby improving the safety of the pipeline system part when an open flame occurs, improving the overall safety, and extending the service life. However, the use environment of industrial robots also varies greatly. Depending on the area with high temperature and humidity, it is easy to cause the shaft temperature of the working robot to be too high, and the robot will also be in a high temperature environment when performing welding work. The high shaft temperature will cause the lubricating oil between the robot shafts to oxidize and deteriorate rapidly. At present, most industrial robots use protective clothing to protect against harsh environments such as dust, static electricity and high temperature, and the protective clothing is difficult to wear and take off. The robot works in a high temperature environment wearing protective clothing, resulting in a rapid increase in the oxidation rate of the lubricating oil, which requires workers to frequently replenish the lubricating oil. The robot wearing protective clothing needs to take off the protective clothing to replenish the lubricating oil. This is very troublesome for robots that need to frequently replenish the lubricating oil in a high temperature environment. The existing oil replenishing mechanism is very complicated and relatively large. Installing it on the robot not only increases the energy consumption of the robot but also affects the flexibility of the robot. Summary of the invention

Firstly, when the device needs to replenish lubricating oil after work is completed, the oil replenishing mechanism 6 is controlled to replenish the oil, and while opening the oil replenishing mechanism 6, the linkage mechanism 7 will be driven to work synchronously, and the linkage mechanism 7 will open the oil drain port, and the internal oxidized and deteriorated lubricating oil will be discharged to the oil drain mechanism through the oil drain port. After the fresh lubricating oil is replenished, the oil replenishing mechanism 6 is closed, and at the same time, the oil drain mechanism is closed synchronously. There is no need for manual contact with the high-temperature machine, and the oil can be replenished without machine cooling. The overall operation is quick and convenient, and there is no need to take off protective clothing. Not only does it reduce the risk of burns caused by manual contact with the machine, but it can also save the steps of putting on and taking off the robot protective clothing, reducing the difficulty of operation, and avoiding the situation where the protective clothing is easily damaged due to frequent putting on and taking off of protective clothing.

[0030] Specifically, the oil replenishing mechanism 6 includes an oil tank 61, a long rod 62, a movable plate 63, two connecting blocks 64, a first through hole 65, a fixed plate 66, a second through hole 67, a mounting plate 68, an electric telescopic rod 69, a first piston plate 610, an airbag 611, a second piston plate 612, a resisting spring 613, a plurality of wedge blocks 614 and a plurality of compression springs 615, the fixed plate 66 is fixedly arranged on the side wall of the second mechanical arm 4, the movable plate 63 is slidably arranged inside the fixed plate 66, the first through hole 65 is arranged on the fixed plate 66, the second through hole 67 is arranged on the movable plate 63, the oil tank 61 is fixedly arranged on the two connecting blocks 64, the mounting plate 68 is fixedly arranged on the side wall of the second mechanical arm 4, The electric telescopic rod 69 is arranged on the mounting plate 68, and the end of the output shaft of the electric telescopic rod 69 is fixedly connected to the end of the movable plate 63. The first piston plate 610 is slidably arranged inside the oil tank 61, and the airbag 611 is arranged on one side of the first piston plate 610.

At this time, the gas inside the airbag 611 is heated and expanded, pushing the first piston plate 610 to move toward the fixed plate 66. The first piston plate 610 squeezes out the lubricating oil inside the oil tank 61, and the lubricating oil enters the interior of the robot along the corresponding first through hole 65 and second through hole 67. After the oil replenishment is completed, the electric telescopic rod 69 is controlled to reset. At this time, the movable plate 63 and the fixed plate 66 are reset, and the first through hole 65 and the second through hole 67 are misaligned, so that the oil tank 61 mouth is closed. At this time, the airbag 611 gradually shrinks to its original state at room temperature, and the air pressure in the sealed space between the first piston plate 610 and the second piston plate 612 becomes smaller. At this time, the left side of the first piston plate 610 is filled with lubricating oil, making the first piston plate 610 unable to move, so the second piston plate 612 and the long rod 6 are driven by the air pressure. 2 moves toward the direction of the first piston plate 610, and because the compression spring 615 is compressed during the movement, the wedge block 614 is clamped in the long rod 62, and after entering the oil tank 61, it is reset under the action of the compression spring 615, thereby contacting the inner wall of the oil tank 61, so as to avoid the second piston plate 612 sliding when the oil is replenished next time, causing the air bag 611 to expand and unable to push the first piston plate 610, so that the lubricating oil cannot be injected into the machine. The overall structure is simple, and there is no need for the cumbersome pressurization operation of the existing automatic refueling mechanism, and the operation of replenishing the lubricating oil can be realized by using the heat energy generated by the machine, and no additional power source is required, which is energy-saving and environmentally friendly. The structure is simple and the protective clothing can be automatically refueled without disassembling it, and the position of the piston can be automatically changed according to the amount of oil in the oil tank 61, so as to ensure that no excess air is injected into the robot during refueling, and the service life of the robot is extended without affecting the flexibility of the normal operation of the robot.

The connecting rod 71 is fixedly arranged at the bottom of the mounting plate 68, the slide rail 72 is fixedly arranged at the bottom of the second mechanical arm 4, the L-shaped rack 74 is fixedly arranged at the bottom of the connecting rod 71, the oil guide column 77 is fixedly arranged at the oil discharge port of the second mechanical arm 4, and the first An oil outlet 79 is set at the bottom of the oil guide column 77, the limit block 73 is fixedly set on the top of the L-shaped rack 74, the two arc-shaped limit plates 710 are fixedly set at the bottom of the oil guide column 77, the two opening and closing plates 78 are slidably set between the two arc-shaped limit plates 710, the two limit columns 711 are respectively fixedly set at the bottom of the two opening and closing plates 78, the turntable 713 is rotatably clamped between the two arc-shaped limit plates 710, the linkage gear ring 76 is fixedly set at the bottom of the turntable 713, the waste oil barrel 75 is set in the middle of the linkage gear ring 76, and the two arc-shaped grooves 712 are set on the turntable 713. The electric telescopic rod 69 is extended to drive the connecting rod 71 and the L-shaped rack 74 to move synchronously, the L-shaped rack 74 moves to drive the linkage gear ring 76 to rotate, the linkage gear ring 76 rotates to drive the waste oil barrel 75 to rotate, the waste oil barrel 75 rotates to drive the turntable 713 to rotate, the turntable 713 rotates to drive the two limit posts 711 to move along the arc groove 712 on the turntable 713, the two limit posts 711 move to drive the two opening and closing plates 78 to open, so that the first oil outlet 79 and the second oil outlet 714 are connected, so that the oxidized and deteriorated lubricating oil inside the robot is discharged into the waste oil barrel 75 for collection. Avoid the deteriorated lubricating oil inside the robot, which causes the newly added fresh lubricating oil to deteriorate, and collect the deteriorated lubricating oil through the waste oil barrel 75 to prevent it from dripping on the surface of the robot to cause the robot to rust and damage, and prevent the surrounding environment from being damaged by the deteriorated lubricating oil, and then treat it uniformly, which is green and environmentally friendly.

[0035] Specifically, the two limiting posts 711 are respectively located in the two arc-shaped grooves 712 and slide.

[0036] Specifically, the interior of the oil guide column 77 is hourglass-shaped.

[0037] Specifically, the L-shaped rack 74 and the linkage gear ring 76 are meshed with each other.

[0038] Specifically, the limit block 73 is slidably matched with the slide rail 72 .

[0039] Working principle: First, when the device needs to be supplemented with lubricating oil after work is completed, the end of the output shaft of the electric telescopic rod 69 is controlled to extend to drive the movable plate 63 to move, so that the second through hole 67 on the movable plate 63 coincides with the first through hole 65. At this time, the gas inside the airbag 611 expands due to heat, pushing the first piston plate 610 to move toward the fixed plate 66. The first piston plate 610 squeezes out the lubricating oil inside the oil tank 61, and the electric telescopic rod 69 extends to drive the connecting rod 71 and the L-shaped rack 74 to move synchronously. The movement of the L-shaped rack 74 drives the linkage gear ring 76 to rotate, and the linkage gear ring 76 The rotation drives the waste oil barrel 75 to rotate, and the rotation of the waste oil barrel 75 drives the turntable 713 to rotate. The rotation of the turntable 713 drives the two limit posts 711 to move along the arc groove 712 on the turntable 713. The movement of the two limit posts 711 drives the two opening and closing plates 78 to open, so that the first oil outlet 79 and the second oil outlet 714 are connected, so that the oxidized and deteriorated lubricating oil inside the robot is discharged into the waste oil barrel 75 for collection, and the lubricating oil enters the interior of the robot along the corresponding first through hole 65 and the second through hole 67. After the oil replenishment is completed, the electric telescopic rod 69 is controlled to reset. At this time, the movable plate 63 and the fixed plate 6 6 is reset, the first through hole 65 and the second through hole 67 are misaligned, so that the oil tank 61 is closed. At this time, the airbag 611 gradually shrinks to its original state at room temperature, and the air pressure in the sealed space between the first piston plate 610 and the second piston plate 612 becomes smaller. At this time, the left side of the first piston plate 610 is filled with lubricating oil, so that the first piston plate 610 cannot move. Therefore, under the action of air pressure, the second piston plate 612 and the long rod 62 are driven to move toward the first piston plate 610, and because the compression spring 615 is compressed during the movement, the wedge block 614 is clamped inside the long rod 62, and after entering the oil tank 61, It is reset under the action of the compression spring 615, thereby resisting the inner wall of the oil tank 61, to prevent the second piston plate 612 from sliding when replenishing oil next time, causing the airbag 611 to expand and unable to push the first piston plate 610, so that the lubricating oil cannot be injected into the machine. There is no need for manual contact with the high-temperature machine, and oil replenishment can be carried out without machine cooling. The overall operation is quick and convenient, and there is no need to take off protective clothing. It not only reduces the risk of burns caused by manual contact with the machine, but also saves the steps of putting on and taking off the robot protective clothing, reduces the difficulty of operation, and avoids the situation where the protective clothing is easily damaged due to frequent putting on and taking off of protective clothing.
