DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0025] The following is combined with Figure 1-3 The utility model is described in further detail.

[0026] Reference Figure 1-3 , an automatic paint stripping tool, comprising: a main body, on which a spray gun mechanism 1, a spray gun moving mechanism 2 and a main body fixing mechanism 3 are provided; the main body fixing mechanism 3 is used to fix the main body in a position to be paint stripped; the spray gun mechanism 1 includes a spray gun 11 for spraying a paint stripping medium; the spray gun moving mechanism 2 is used to drive the spray gun 11 to move on the main body, so that when in use, the main body is fixed in a position to be paint stripped by the main body fixing mechanism 3, and the outlet of the spray gun 11 is directed toward the paint surface for paint stripping, and at the same time, the spray gun moving assembly 2 drives the spray gun 11 to move to strip paint surfaces at different positions. Therefore, during the paint stripping process, there is no need for manual uninterrupted operation of the tool, the operation difficulty is low, the paint stripping quality is guaranteed, and the safety hazards are reduced.

[0027] Reference Figure 1-3 In order to drive the spray gun to move smoothly on the main body and ensure the quality of paint removal, the spray gun moving mechanism 2 includes a screw 21 and a power assembly. The screw 21 is rotatably arranged on the main body, and the power assembly is used to drive the screw 21 to rotate; the spray gun mechanism 1 also includes a mounting seat 12, which is sleeved on the screw 21 and threadedly connected to the screw 21. The spray gun 11 is arranged on the mounting seat 12. In this way, since the mounting seat 12 is threadedly matched with the screw 21, the mounting seat 12 can be driven to move by driving the screw 21 to rotate, and then the spray gun 11 can be moved to gradually remove paint from different positions of the paint surface to be removed. The power component can be a motor 22, which is set on the main body. The output end of the motor 22 is coaxially connected to the screw 21. In this way, the motor 22 does work to make the screw 21 rotate forward or reverse, controlling the movement of the spray gun 11. In order to limit the movement of the mounting seat 12 so that the mounting seat 12 can only make a translational movement along the axial direction of the screw 21, a guide rod 4 is provided on the main body. The guide rod 4 passes through the mounting seat 12, and the axial direction of the guide rod 4 is consistent with the axial direction of the screw 21. Through the cooperation of the screw 21 and the guide rod 4, the mounting seat 12 moves smoothly on the main body, thereby ensuring the paint removal quality of the spray gun 11.

[0028] Further optimization is, Figure 3As shown, in order to prevent safety accidents caused by uncontrollable factors, the main body is provided with limit sensors 5 at both ends of the guide rod 4. When the movement of the mounting seat 12 exceeds the limit range, it is detected by the limit sensor 5 on that side (the limit sensor 5 can be an infrared sensor, etc.), so that the fault can be adjusted in time.

[0029] A further optimization is that in order to avoid splashing of waste materials such as media and paint residue after paint removal, a paint removal cavity 6 with a downward opening is provided on the main body, and a spray gun 11 is placed in the paint removal cavity 6. The main body is provided with a sand suction port 7 on one side of the paint removal cavity 6. In this way, when removing paint, the sand is recovered to the debris bucket through a recovery pipeline provided at the sand suction port 7.

[0030] like Figure 1 and Figure 2 As shown, in order to stably fix the main body, the main body fixing mechanism 3 includes a plurality of suction cup assemblies arranged on both sides of the main body. The suction cup assemblies can adopt vacuum corrugated suction cups. The main body is fixed by multiple suction cup assemblies so that the device will not move during paint removal.

[0031] Further optimization is, Figure 1-Figure 3 As shown, in order to facilitate the adjustment of the nozzle direction of the spray gun 11, the spray gun mechanism 1 also includes a connecting pipe 13 and an angle adjustment rod 14. The connecting pipe 13 is connected to the spray gun 11, and the connecting pipe 13 is rotatably set on the mounting seat 12. One end of the angle adjustment rod 14 is connected to the ring side of the connecting pipe 13. In this way, by rotating the angle adjustment rod 14, the connecting pipe 13 is rotated, so that the nozzle direction of the spray gun 11 is changed. In order to ensure that the nozzle direction is in a suitable range, two limit slots 15 are provided on the mounting seat 12. The two limit slots 15 are located on both sides of the angle adjustment rod 14, so as to limit the rotation range of the angle adjustment rod 14 and the direction range of the nozzle of the spray gun 11. In order to facilitate the operation of the angle adjustment rod 14, the angle adjustment rod 14 is arranged on the outside of the main body.

[0032] A further optimization is that, in order to facilitate the setting of various working parameters (walking distance, moving speed, etc.), a control panel 8 is provided on the main body, and various parameters are set through the control panel 8.

[0033] In actual use, first place the entire paint removal tool on the product to be worked on, adjust the position of the main body of the automatic paint removal tool shell, and then connect the pipeline sand suction port 7, the air distribution valve block, the sand pipe interface, and the control wire interface on the paint removal tool. Adjust the suction cup assembly according to the actual situation of the paint removal surface, and fit the bottom surface of the four sets of vacuum corrugated suction cups to the contact surface of the product. Then press the suction cup start button on the control panel 8. The four sets of vacuum corrugated suction cups work simultaneously to firmly fix the automatic paint removal tool on the surface to be worked on, and adjust the spray gun 11 parameters (angle, pressure, distance, etc.). Finally, press the spray gun 11 switch on the control panel 8. The spray gun moving mechanism 2 automatically moves inside the paint removal tool body to perform the paint removal operation. It runs according to the parameters until the end. The spray gun moving mechanism 2 will automatically stop and reset, thereby ensuring the quality of paint removal. And the spray gun moving mechanism 2 can be manually intervened to stop the paint removal work in the middle. Flexible and changeable usage modes are more suitable for modern paint removal requirements;

[0034] This application is mainly used in the automatic paint removal operation for local repair of product surfaces. It is a mechanism for automatic mobile paint removal by medium spraying. This mechanism can be applied to mobile paint removal operations on various types of product surfaces, and the walking distance, moving speed and spray gun angle of the mobile mechanism can be adjusted to meet the requirements of the local repair paint removal process. The paint removal quality is uniform, saving time and effort, so that the paint removal operation can be carried out more safely and effectively.

[0035] In summary, the present application has the following advantages: safety and efficiency: the spray gun moving mechanism 2 is used to move the spray gun 11, and the vacuum suction cup assembly is used to stably and efficiently fix the paint removal tool, which can quickly adsorb the fixed tool and steadily perform the paint removal work. No human intervention is required during paint removal, which is truly safe and efficient.

[0036] Strong applicability: The spray gun moving mechanism 2 can control the range of movement of the spray gun 11, which can adapt to various requirements of local repair and paint removal, and can accurately control the size of the location area to be removed, which is suitable for a variety of scenarios;

[0037] Easy to use: After setting the parameters in advance, the spray gun 11 can be started with one button and can move back and forth or one-way according to the settings, which is more time-saving, labor-saving, fast and convenient;

[0038] Cost savings: One tool can be used to repair and remove paint from various parts of the machine, eliminating the need to change tooling and saving significant costs.

[0039] High reliability: The stepper motor drives the ball screw to drive the spray gun 11 to move, which runs smoothly and moves at a uniform speed, ensuring the quality and process of paint removal. It cooperates with the limit sensor to prevent over-limit, which is safer and more reliable.

[0040] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
