When the sliding rod moves, it will drive the piston to move in the sleeve. When the piston moves out of the sleeve, negative pressure suction will be generated, and the lubricating oil will be drawn into the sleeve through the oil inlet pipe. When the piston moves into the sleeve, the oil inlet one-way valve will be closed, so that the lubricating oil is squeezed and passes through the multi-stage filtering component.

[0018] 2. By setting up a pre-filter component, the pre-filter component uses the internal flow tube to extend the flow path of the lubricating oil, and then uses the magnetic rod set in the flow tube to contact the lubricating oil. The magnetism of the magnetic rod is used to adsorb ferromagnetic debris in the lubricating oil, so that the lubricating oil is preliminarily filtered, reducing the filtering pressure of the subsequent multi-stage filtering components and improving the filtering efficiency.

DETAILED DESCRIPTION

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 , a multi-layer filtering system for lubricating oil of an intelligent robot, comprising a sleeve 1, a piston 14 is provided in the sleeve 1, the end surface of the piston 14 is provided with a sliding rod 2 passing through the sleeve 1, the front end of the sliding rod 2 is provided with a second rotating shaft 12, the end surface of the second rotating shaft 12 is provided with a second clamp 13 connected to the robot's small arm, the tail end of the sleeve 1 is provided with a rear end cover 5, the outer end of the rear end cover 5 is provided with a hinged frame 7, the inner end is provided with a multi-stage filtering component 4, a first rotating shaft 8 is provided in the hinged frame 7, the end surface of the first rotating shaft 8 is provided with a first clamp 9 connected to the robot's large arm, an oil inlet pipe 11 is provided below the sleeve 1 between the piston 14 and the multi-stage filtering component 4, an oil inlet check valve 15 is provided in the oil inlet pipe 11, an oil outlet pipe 10 is provided below the sleeve 1 between the rear end cover 5 and the multi-stage filtering component 4, an oil outlet check valve 17 is provided in the oil outlet pipe 10;

[0027] In the present invention, a sleeve 1 and a piston 14 are provided. When the robot's upper arm and lower arm move, the articulated frame 7 and the slide rod 2 will be driven to move through the first clamp 9 and the second clamp 13. When the slide rod 2 moves, the piston 14 will be driven to move in the sleeve 1. When the piston 14 moves out of the sleeve 1, a negative pressure suction force will be generated, and the lubricating oil will be drawn into the sleeve 1 through the oil inlet pipe 11. When the piston 14 moves into the sleeve 1, the oil inlet one-way valve 15 will be closed, so that the lubricating oil is squeezed to pass through the multi-stage filter component 4. The lubricating oil is filtered by the multi-stage filter component 4, and the filtered lubricating oil is discharged through the oil outlet pipe 10, thereby achieving the purpose of filtering the lubricating oil by the robot's own movement. The structure is simple and no driving equipment is required.

[0028] The multi-stage filter component 4 includes a support rod 401 connected to the rear end cover 5. The support rod 401 is provided with a stopper 402 and a nut 403. A perforated clamping plate 404 and filter paper 405 are provided between the stopper 402 and the nut 403 on the support rod 401. The perforated clamping plates 404 and the filter paper 405 are alternately arranged.

[0029] By setting up the perforated splint 404 and the filter paper 405, the filter paper 405 can filter the lubricating oil, absorb impurities and debris in the lubricating oil, and use the pressure of the piston 14 to push it, so that the filtering effect is better and the efficiency is higher. The perforated splint 404 can support the filter paper 405, so that the filter paper 405 can completely cover the inside of the sleeve 1, ensuring the efficiency and effect of the filtration. At the same time, the holes on the perforated splint 404 can support the lubricating oil while allowing it to flow smoothly.

[0030] A sealing ring 16 is provided between the inner wall of the sleeve 1 and the multi-stage filter component 4. The sealing ring 16 is used to prevent the lubricating oil from passing through the multi-stage filter component 4.

[0031] By setting the sealing ring 16, the sealing ring 16 can close the gap between the multi-stage filter component 4 and the inner wall of the sleeve 1, preventing the pressurized lubricating oil from passing through the gap and over the multi-stage filter component 4, avoiding the outflow of unfiltered lubricating oil, and ensuring the quality and effect of the filtration.

[0032] A pre-filter component 3 is connected below the oil inlet pipe 11. The pre-filter component 3 is used for coarse filtering of lubricating oil. The pre-filter component 3 includes a flow pipe 301. An oil outlet 302 is formed at one end of the flow pipe 301, and an oil inlet 303 is formed at the other end. The oil outlet 302 is connected to the oil inlet pipe 11. A sealing plate 304 is inserted below the flow pipe 301, and a magnetic rod 305 is provided on the sealing plate 304.

[0033] By setting up a pre-filter component 3, the pre-filter component 3 uses the internal circulation tube 301 to extend the flow path of the lubricating oil, and then uses the magnetic rod 305 provided in the circulation tube 301 to contact the lubricating oil. The magnetism of the magnetic rod 305 is used to adsorb ferromagnetic debris in the lubricating oil, so that the lubricating oil is preliminarily filtered, reducing the filtering pressure of the subsequent multi-stage filtering component 4 and improving the filtering efficiency.

[0034] The sleeve 1 is provided with a locking component 6, which is in contact with the rear end cover 5. The locking component 6 includes a connecting plate 601 provided on the sleeve 1, a pin 603 is provided in the connecting plate 601, a connecting frame 604 is provided on the pin 603, and a threaded rod 605 is provided on the connecting frame 604. The threaded rod 605 is in contact with the rear end cover 5.

[0035] By setting the connecting frame 604 and the threaded rod 605, when the rear end cover 5 needs to be locked, the connecting frame 604 is rotated onto the rear end cover 5, and then the threaded rod 605 is tightened so that the threaded rod 605 fits the rear end cover 5 and is squeezed onto the tail end of the sleeve 1. When the rear end cover 5 needs to be opened, the threaded rod 605 is loosened and the connecting frame 604 is rotated outward. In this way, all structures of the locking component 6 can be connected to the sleeve 1, which can avoid the loss of parts.

[0036] A coil spring 602 is sleeved on the pin 603, and the other end of the coil spring 602 is connected to the connecting plate 601;

[0037] By setting the coil spring 602, the coil spring 602 supports and limits the pin shaft 603 and applies an elastic force to rotate the pin shaft 603 outward, so that the connecting frame 604 can be automatically unfolded after being released, which facilitates the disassembly of the rear end cover 5 and the replacement of the multi-stage filter component 4.

[0038] Working principle: During installation, connect the first clamp 9 to the robot's upper arm and the second clamp 13 to the robot's lower arm. Then, when the robot moves, the upper arm and the lower arm drive the slide rod 2 to move in the sleeve 1, and drive the piston 14 to move. When the piston 14 moves out of the sleeve 1, a negative pressure suction force is generated in the sleeve 1 to suck the lubricating oil through the oil inlet pipe 11. When the piston 14 moves into the sleeve 1, the piston 14 will squeeze the lubricating oil, so that the lubricating oil is pressurized and passes through the multi-stage filter component 4. After filtration, it is discharged through the oil outlet pipe 10, thereby achieving the effect of filtering the lubricating oil.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
