Description

Technical Field

[0001] The present invention relates to the technical field of automobile maintenance mechanical arms, and in particular to an automobile intelligent maintenance and spraying mechanical arm. Background Art

[0002] The automobile intelligent maintenance spraying robot arm is a highly automated spraying equipment designed specifically for automobile maintenance and spraying operations. It combines robot arm technology, spraying technology and intelligent control technology, and can achieve efficient, precise and stable spraying operations during automobile maintenance.

[0003] When a car needs to be repaired by spraying paint, a spray robot arm is used to spray paint the positions that need to be painted. When spraying, due to the different sizes of the areas that need to be sprayed, it is necessary to control the distance between the nozzle and the area that needs to be sprayed multiple times during spraying. At the same time, since the nozzle sprays in an atomized manner, the paint liquid will be atomized and sprayed into the air. If the air flows, the spraying will not be uniform, further reducing the spraying efficiency. Improvements need to be made to this problem. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent automobile repair and painting robot arm to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an automobile intelligent maintenance spraying robot arm, comprising a rotating base, a driving assembly, a deformation assembly and a wall scraping assembly, an adjusting arm is arranged on the top of the rotating base, a paint spraying arm tube is rotatably connected to the inner side of the top of the adjusting arm, a paint spraying head is arranged on the side of the paint spraying arm tube away from the adjusting arm, and a feeding pipe is arranged on the other side of the paint spraying arm tube.

[0006] Wherein, the driving component comprises:

[0007] A fixed disc is fixedly connected to the outside of the paint spray arm tube. A positioning disc is fixedly connected to the outer wall of the paint spray arm tube and is located close to the paint spray head. An electric telescopic rod is fixedly connected to the side of the fixed disc close to the positioning disc. The electric telescopic rod has a telescopic end. The telescopic end of the electric telescopic rod is fixedly connected to a connecting rod. The connecting rod is fixedly connected to a movable disc at one end away from the electric telescopic rod.

[0008] According to the above technical solution, the deformation assembly includes a deformation frame 1, a telescopic rod, a deformation frame 2, a protective enclosure, a positioning frame and a drainage trough. The deformation frame 1 is fixedly connected to the outside of the movable disc, the telescopic rod is rotatably connected to the middle of the deformation frame 1, the deformation frame 2 is rotatably connected to the other side of the telescopic rod, the protective enclosure is fixedly connected to the side of the deformation frame 2 away from the telescopic rod, the positioning frame is fixedly connected to the outside of the positioning disc, and the drainage trough is opened on the side of the protective enclosure away from the positioning frame.

[0009] According to the above technical solution, the wall scraper assembly includes an airbag, a connecting hose, a connecting pipe rack, an adjusting box, a spring, a piston moving frame and a scraper plate. The airbag is fixedly connected to the side of the moving disc close to the positioning disc, the connecting hose is fixedly connected to the outside of the airbag, the connecting pipe rack is fixedly connected to the end of the connecting hose away from the airbag, the adjusting box is fixedly connected to the inner wall of the protective enclosure, the spring is fixedly connected to the inner wall of the adjusting box, the piston moving frame is fixedly connected to the other end of the spring, and the scraper plate is fixedly connected to the side of the piston moving frame away from the piston moving frame.

[0010] According to the above technical solution, a circular groove is opened in the middle of the movable disc, and the movable disc is slidably connected to the outer wall of the paint spray arm tube through the circular groove. The telescopic end of the electric telescopic rod passes through the positioning disc and is fixedly connected to the connecting rod. A circular hole is opened in the positioning disc to accommodate the movement of the telescopic end of the electric telescopic rod, so that the electric telescopic rod can drive the connecting rod to move.

[0011] According to the above technical solution, the middle portion of the positioning frame is rotatably connected to the side of the protective enclosure close to the positioning disc, so that the protective enclosure can rotate around the middle portion of the positioning frame.

[0012] According to the above technical solution, the connecting pipe rack is fixedly connected to the regulating box at one end away from the connecting hose, and the airbag is connected to the regulating box through the connecting hose and the connecting pipe rack, so that the air in the airbag is transported to the regulating box through the connecting hose and the connecting pipe rack.

[0013] According to the above technical solution, the piston moving frame is slidably connected to the inner wall of the adjustment box, and the scraper plate is in contact with the inner wall of the protective enclosure on one side close to the protective enclosure, so that the scraper plate can scrape the inner side of the protective enclosure when it moves.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when maintenance spraying work is required, the present invention controls the rotating base, the adjusting arm and the spraying arm pipe to work, and can adjust the spraying position of the spraying head. Then, the feed pipe on the spraying arm pipe passes the external paint liquid into the spraying head, controls the work of the spraying head, and sprays the place where spraying is required.

[0015] When the spraying range is small, the electric telescopic rod is controlled to work. When the electric telescopic rod is working, the electric telescopic rod pushes the connecting rod to move, so that the moving disc on the other side of the connecting rod slides on the outside of the paint spraying arm tube. At the same time, when the moving disc is moving, the deformation frame 1 on the moving disc pulls the telescopic rod to make the telescopic rod extend and retract. At the same time, the telescopic rod pulls the deformation frame 2 when extending and retracting, so that the deformation frame 2 synchronously drives the protective enclosure to move. Since the protective enclosure is rotatably connected with the positioning frame outside the positioning disc, the protective enclosure rotates around the positioning frame to get close to the outside of the paint spraying arm tube, and the protective enclosure moves to the outside of the paint spraying head, so as to protect the outside of the paint spraying head and prevent the outside air flow from disturbing the flow direction of the atomized paint liquid of the paint spraying head. At the same time, the atomized paint liquid sprayed by the paint spraying head can be gathered in front of the paint spraying head, and the excess atomized paint liquid adheres to the inside of the protective enclosure to prevent the atomized paint liquid from escaping into the air and being inhaled by the human body. It can also prevent the paint spraying head from being disturbed by external objects, thereby ensuring the safety of the paint spraying head when spraying.

[0016] When the spraying range is large, the electric telescopic rod is controlled to work, so that the electric telescopic rod pulls the connecting rod, so that the moving disc moves along the outer wall of the spray arm tube, and at the same time, the moving disc on the connecting rod pushes the deformation frame 1, and the deformation frame 1 further pushes the telescopic rod, so that the deformation frame 2 and the protective enclosure on the other side of the telescopic rod are stressed, so that the protective enclosure rotates outward around the positioning frame, thereby expanding the front area of ​​the spray head, and the area of ​​the spray head during spraying can be adjusted. At the same time, the protective enclosure can be set to protect the spray head and adhere to the atomized paint liquid dissipated in the air, ensuring that when the spraying size changes, the protective enclosure can still protect the spray head and prevent a large amount of atomized paint liquid from dissipating in the air.

[0017] After the painting is finished, the excess atomized paint liquid adheres to the inner side of the protective enclosure. At this time, the paint arm pipe is controlled to work so that the paint head is aimed at the lower side, and then the electric telescopic rod is controlled to work so that the connecting rod drives the moving disc to move close to the positioning disc and squeeze the airbag. When the airbag is squeezed, the internal air is transmitted to the connecting pipe rack through the connecting hose, and the air is transported to the regulating box through the connecting pipe rack, so that the pressure in the regulating box increases and the piston moving rack is pushed to work. At this time, the spring is stretched, so that the scraper plate on the piston moving rack scrapes the inner wall of the protective enclosure, and the excess paint liquid flows out through the scraper plate on the protective enclosure, so that the device has a self-cleaning function.

The airbag 701 is fixedly connected to the side of the moving disc 405 close to the positioning disc 402, the connecting hose 702 is fixedly connected to the outside of the airbag 701, the connecting pipe rack 703 is fixedly connected to the end of the connecting hose 702 away from the airbag 701, the adjusting box 704 is fixedly connected to the inner wall of the protective enclosure 604, the spring 705 is fixedly connected to the inner wall of the adjusting box 704, the piston moving rack 706 is fixedly connected to the other end of the spring 705, and the scraper plate 707 is fixedly connected to the side of the piston moving rack 706 away from the piston moving rack 706.

[0037] The piston moving frame 706 is slidably connected to the inner wall of the adjustment box 704, and the scraper plate 707 is close to the inner wall of the protective enclosure 604, so that the scraper plate 707 can scrape the inner side of the protective enclosure 604 when moving.

[0038] When the spraying range is small, the electric telescopic rod 403 is controlled to work. When the electric telescopic rod 403 is working, the electric telescopic rod 403 pushes the connecting rod 404 to move, so that the moving disc 405 on the other side of the connecting rod 404 slides outside the spray arm tube 3. At the same time, when the moving disc 405 moves, the deformation frame 1 601 on the moving disc 405 pulls the telescopic rod 602 to make the telescopic rod 602 extend and retract.

It can also prevent the paint spray head 5 from being disturbed by external objects, thereby ensuring the safety of the paint spray head 5 when spraying paint.

[0039] When the spraying range is large, the electric telescopic rod 403 is controlled to work, so that the electric telescopic rod 403 pulls the connecting rod 404, and the movable disc 405 moves along the outer wall of the paint spray arm tube 3. At the same time, the movable disc 405 on the connecting rod 404 pushes the deformation frame 1 601, and the deformation frame 1 601 further pushes the telescopic rod 602, so that the deformation frame 2 603 and the protective enclosure 604 on the other side of the telescopic rod 602 are subjected to force, so that the protective enclosure 604 rotates outward around the positioning frame 605, thereby expanding the front area of ​​the paint spray head 5, and the area of ​​the paint spray head 5 during spraying can be adjusted. At the same time, the protective enclosure 604 can be set to protect the paint spray head 5 and adhere to the atomized paint liquid dissipated in the air, ensuring that when the spraying size changes, the protective enclosure 604 can still protect the paint spray head 5 and prevent a large amount of atomized paint liquid from dissipating in the air.

[0040] After the painting is finished, the excess atomized paint liquid adheres to the inner side of the protective enclosure 604. At this time, the paint spray arm tube 3 is controlled to work so that the paint spray head 5 is aimed at the lower side, and then the electric telescopic rod 403 is controlled to work so that the connecting rod 404 drives the moving disc 405 to move close to the positioning disc 402, and squeezes the airbag 701. When the airbag 701 is squeezed, the internal air is transmitted to the connecting pipe rack 703 through the connecting hose 702, and the air is transported to the regulating box 704 through the connecting pipe rack 703, so that the pressure in the regulating box 704 increases and the piston moving rack 706 is pushed to work. At this time, the spring 705 is stretched, so that the scraper plate 707 on the piston moving rack 706 scrapes the inner wall of the protective enclosure 604, and the excess paint liquid flows out through the scraper plate 707 on the protective enclosure 604, so that the device has a self-cleaning function.
