Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically an explosion-proof robotic automatic spray booth. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Currently, most polyurea spraying in China involves manual or robotic spraying, both of which result in the formation of a large amount of mist-like coating within the spray booth. Furthermore, due to the properties of the coating, polyurea cures rapidly after spraying, easily contaminating the interior walls of the spray booth. Therefore, effectively protecting the spray booth and quickly removing the polyurea that has dispersed within it are pressing technical problems that need to be solved.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an explosion-proof robotic automatic spray booth. This new type of automatic explosion-proof spray booth can achieve automatic polyurea spraying in confined spaces, while effectively preventing internal wall contamination from drifting polyurea.

[0006] This application discloses an explosion-proof robotic automatic paint spraying booth, comprising: A paint spraying chamber having a sealed chamber, the inner wall of which is coated with a layer of transparent lithium-based lubricating oil; A spraying robot unit is disposed within the sealed chamber to spray the workpiece located within the sealed chamber; An air intake unit is disposed within the sealed chamber and located above the painting robot unit. The airflow generated by the air intake unit flows downward to act on the working part of the painting robot. An exhaust unit is disposed within the sealed chamber and located on one side of the painting robot unit, wherein the material is located between the painting robot unit and the exhaust unit.

[0007] Furthermore, the air intake unit includes a static pressure box assembly and an air intake nozzle assembly. The airflow in the static pressure box assembly flows downward through the air intake nozzle assembly and is blown into the sealed chamber.

[0008] Furthermore, the air inlet nozzle assembly includes multiple air inlet nozzles, which are evenly distributed on the top of the paint spraying chamber, and the vertical projection of the air inlet nozzles covers the painting robot unit.

[0009] Furthermore, the exhaust unit includes an exhaust port, an exhaust pump, and an exhaust channel. The exhaust port is subjected to negative pressure by the exhaust pump to draw in the spray material dispersed in the sealed chamber.

[0010] Furthermore, the air extraction port is located vertically below the working part of the spraying robot unit.

[0011] Furthermore, the exhaust channel adopts a labyrinth structure so that the exhaust airflow flows in a reciprocating and zigzagging path.

[0012] Furthermore, it also includes a hoisting unit, which is used to hoist the material and can drive the material to rotate relative to the painting robot unit.

[0013] Furthermore, the spraying robot unit includes a five-axis robotic arm and a spraying action part disposed on the five-axis robotic arm.

[0014] Based on the above technical solutions, the beneficial effects of this utility model are as follows: The spray painting chamber in this application has a relatively small space design. Through the introduction of an air inlet unit and an exhaust unit, the air inlet unit forms a vertically downward airflow within the spray painting chamber, and the exhaust unit can quickly extract the airflow flowing to or near the bottom of the spray painting chamber to the outside, thereby achieving automatic spraying in a small space. At the same time, effective measures are taken to prevent the dispersion of spray material from contaminating the inner wall of the spray painting chamber. In addition, a transparent lithium-based lubricating oil layer is coated on the inner wall of the sealed chamber. This transparent lithium-based lubricating oil layer can adhere to the spray material (polyurea) without reacting with each other, thus having no impact on the spraying quality of the material surface. After accumulating for a period of time, it can be easily peeled off, keeping the inner wall of the spray painting chamber clean.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] Combination Figure 1 and Figure 2 As shown, this embodiment discloses an explosion-proof robotic automatic spray painting chamber, including a spray painting chamber 1, a spraying robot unit 2, an air inlet unit 3, an exhaust unit 4, and a hoisting unit 5. The hoisting unit 5 is used to hoist the material 6, and the spraying robot unit 2 is responsible for spraying the surface of the hoisted material 6. Since the space design of the spray painting chamber 1 in this application is relatively small, the air inlet unit 3 and the exhaust unit 4 are introduced. The air inlet unit 3 forms a vertically downward airflow within the spray painting chamber 1, and the exhaust unit 4 can quickly extract the airflow flowing to or near the bottom of the spray painting chamber 1 to the outside, thus achieving automatic spraying in a confined space. At the same time, effective measures are taken to prevent contamination of the inner wall of the spray painting chamber 1 by the scattered spray material.

[0022] In this embodiment, the spraying chamber has a sealed chamber, and the inner wall of the sealed chamber is coated with a transparent lithium-based lubricating oil layer. This transparent lithium-based lubricating oil layer can adhere to the spray material (polyurea) and does not react with each other, so it has no effect on the spraying quality of the surface of the material 6. After accumulating for a period of time, it can be easily peeled off, keeping the inner wall of the spraying chamber 1 clean.

[0023] In this embodiment, the spraying robot unit 2 is disposed within the sealed chamber to spray the workpiece 6 located within the sealed chamber. Specifically, the spraying robot unit 2 includes a five-axis robotic arm and a spraying action unit disposed on the five-axis robotic arm. It is worth noting that the spraying action unit can be tilted relative to the workpiece 6. When spraying the front edge, the tilted spraying can cover half of the side wall area, and when spraying the back edge, the tilted spraying can cover the other half of the side wall area. Thus, double-sided spraying can complete the overall surface spraying of the workpiece 6, wherein the tilt angle is controlled at approximately 15°.

[0024] In this embodiment, the air inlet unit 3 is disposed within the sealed chamber and located above the spraying robot unit 2. The airflow generated by the air inlet unit 3 flows downward to act on the working part of the spraying robot. Specifically, the air inlet unit 3 includes a static pressure box assembly 31 and an air inlet nozzle assembly 32. The airflow in the static pressure box assembly 31 flows downward through the air inlet nozzle assembly 32 and is blown into the sealed chamber. The air inlet nozzle assembly 32 includes multiple air inlet nozzles, which are evenly distributed on the top of the spraying chamber 1, and the vertical projection of the air inlet nozzles covers the spraying robot unit 2. In the above arrangement, the airflow of the air inlet nozzles is controlled at 0.4 m / s, the main purpose of which is to uniformly and completely drive the dispersed spray material towards the bottom of the sealed chamber.

[0025] In this embodiment, the exhaust unit 4 is disposed within a sealed chamber and located on one side of the spraying robot unit 2, wherein the material component 6 is located between the spraying robot unit 2 and the exhaust unit 4. The main purpose is that the exhaust unit 4 can effectively collect the sprayed material dispersed after spraying. Specifically, the exhaust unit 4 includes an air intake, an air pump, and an exhaust channel 41. The air intake is subjected to negative pressure by the air pump to draw in the sprayed material dispersed within the sealed chamber. Preferably, in one embodiment, the air intake is located vertically below the working part of the spraying robot unit 2 to effectively collect all the sprayed material. The exhaust channel 41 adopts a labyrinthine structure, causing the exhaust airflow to flow in a reciprocating path, aiming to maximize the contact between the dispersed sprayed material and the material forming the suction channel, thus ensuring the sprayed material adheres to the material.

[0026] In this embodiment, the hoisting unit 5 is used to hoist the material part 6 and can drive the material part 6 to rotate relative to the spraying robot unit 2, so as to realize stepless adjustment of the front and back of the material part 6, and can adjust the vertical position of the material part 6 to cooperate with the action of the robot spraying unit.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
