Description

Technical Field

[0001] The utility model belongs to the field of truss robots, and particularly relates to a structure of a cantilever truss robot. Background Technique

[0002] The cantilever truss robot is a robot with a light structure, having a cantilever design to cover a large working area, high load capacity, operational flexibility and light weight characteristics, and is suitable for occasions such as automated production lines and warehousing logistics that require large-range operations.

[0003] The existing cantilever truss robots usually drive the cantilever to move through a rack and pinion. At the same time, in order to ensure smoothness, lubricating fluid usually needs to be applied at the meshing position of the rack and the pinion. However, the lubricating fluid has a certain viscosity and is easy to adhere to dust and impurities in the air. After long-term use, a large amount of dust accumulates, which may affect the meshing effect of the rack and pinion, and further affect the movement accuracy of the robot.

[0025] Cleaning unit 12, the cleaning unit 12 includes a gearbox 13 fixedly connected to the motor base 11. On one side of the gearbox 13, there is a cleaning box 14. An air filter box 15 is movably arranged in the cleaning box 14. On one side of the upper end of the air filter box 15, a brush base 16 is fixedly arranged. On the side surface of the brush base 16, there are bristles 17 for cleaning. A filter screen 18 for filtering is also fixedly arranged in the air filter box 15. An inlet 19 is arranged at the upper end of the cleaning box 14. A dust-proof cover 20 for sealing and dust-proof is movably arranged in the inlet 19. A sealing rubber ring 21 is fixedly arranged at the lower end of the outer side of the dust-proof cover 20. A sewage outlet 22 for discharging sewage is arranged at the lower end of the cleaning box 14. A liquid pump 23 is also fixedly arranged in the cleaning box 14. The upper end of the liquid pump 23 is connected to an infusion tube 24. The end of the infusion tube 24 is bifurcated and connected to two groups of nozzles 25. The nozzles 25 are inclined above the tooth surface of the rack 4.

[0026] In an embodiment of the present utility model, through the provided gearbox 13, it can be used for dust-proof of the gear 10. Then, through a group of nozzles 25 arranged to wash the tooth surface of the rack 4, the dirt can be softened. Then, the softened dirt is brushed off by the bristles 17. Then, through another group of nozzles 25 arranged to perform secondary washing and lubrication on the tooth surface of the rack 4 to ensure subsequent use. Through the provided filter screen 18, the flowing-down cleaning liquid can be filtered to remove impurities in the cleaning liquid, collected by the air filter box 15 for convenient cleaning. The filtered cleaning liquid can also be reused to reduce waste of resources.

[0027] In an example of the present utility model, during use, cleaning liquid is injected into the cleaning box 14 through the inlet 19. The robot main body 8 is started to drive the gear 10 to rotate. Under the meshing action of the gear 10 and the rack 4, relative movement is generated between the gear 10 and the rack 4. Under the limitation of the slide rail 5 and the slider 6, the gear 10 drives the cantilever 7 to move. The liquid pump 23 is started to extract the cleaning liquid, which is split by the infusion tube 24 and sprayed onto the tooth surface of the rack 4 through the nozzles 25. One group of nozzles 25 washes and softens the dirt on the tooth surface of the rack 4. The softened dirt is scraped and brushed off the tooth surface of the rack 4 by the bristles 17. Then, through another group of nozzles 25 arranged to perform secondary washing and lubrication on the tooth surface of the rack 4, the cleaning liquid flowing down from the tooth surface of the rack 4 is collected by the air filter box 15, filtered by the filter screen 18 and then returned to the cleaning box 14. The impurities generated by the filtration are stored in the air filter box 15. After long-term use, the cleaning liquid needs to be replaced. The old cleaning liquid is discharged through the sewage outlet 22, the air filter box 15 is taken out and cleaned, and then the air filter box 15 is inserted back into the cleaning box 14, and new cleaning liquid is poured through the inlet 19.

[0028] Such as Figures 1 to 3As shown, as a preferred embodiment of the present utility model, the cantilever 7 is perpendicular to the truss 2. The side surface of the motor base 11 is fixedly connected to the side surface of the cantilever 7, and the gearbox 13 is bolted to the motor base 11.

[0029] Furthermore, the gearbox 13 is provided with a box-shaped structure, the cleaning box 14 is provided with a box-shaped structure, the cleaning box 14 and the gearbox 13 are integrally formed, and openings adapted to the rack 4 are provided on the side surfaces of both the gearbox 13 and the cleaning box 14 corresponding to the rack 4.

[0030] In an example of the present utility model, the provided gearbox 13 can be used for dust prevention of the gear 10, and its integrally formed structure also facilitates processing, production, and installation.

[0031] As Figures 4 to 6 shown, as a preferred embodiment of the present utility model, the filter box 15 is provided with a frame-shaped structure. One end of the filter box 15 penetrates through the cleaning box 14 and is flush with the outside of the cleaning box 14, and the other end of the filter box 15 is movably located inside the side wall of the cleaning box 14. A card strip 151 for limiting is provided on one side of the filter box 15, and a card slot 141 adapted to the size of the card strip 151 is fixedly provided at the position corresponding to the card strip 151 on the inner side of the cleaning box 14. The brush holder 16 is provided with an "L"-shaped plate-like structure, and the brush holder 16 is integrally formed with the filter box 15.

[0032] In an example of the present utility model, the limitation of the filter box 15 by the provided card strip 151 facilitates the installation of the filter box 15. By setting the brush holder 16 as an "L"-shaped plate, it can prevent the filter box 15 from being blocked by the bristles 17 when being pulled out. Based on the split structure of the filter box 15, it also facilitates the cleaning and maintenance of the bristles 17 and the filter screen 18.
