Description

Technical Field

[0001] This utility model relates to the field of automatic spraying, and in particular to an automatic spraying device. Background Technology

[0002] A shipping container is a type of container used for transporting goods when combining different modes of transport such as sea, land, and air. During the manufacturing process, the inner and outer surfaces of a container are usually painted with different colors of paint. Meanwhile, the door frame of the container, which marks the boundary between the inner and outer surfaces, must be painted with the same color as the inner or outer surface, depending on the specific requirements, and the paint boundary at the dividing point must be clear and free of splashes.

[0003] However, the current process in container factories uses high-pressure airless spraying (the supply pressure is usually greater than 100 bar), where workers use baffles to cover one side of the door frame for spraying. This has drawbacks such as high labor costs, poor working environment, and low paint utilization. Utility Model Content

Detailed Implementation

[0022] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0023] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The door frame of a container serves as the boundary between the inner and outer surfaces. It requires painting with a topcoat of the same color as either the inner or outer surface, ensuring a clear and splash-free paint boundary. Currently, container factories use high-pressure airless spraying (supply pressure typically exceeding 100 bar), where workers use a shield to cover one side of the door frame during spraying. This method suffers from high labor costs, poor working conditions, and low paint utilization. Therefore, an automated spraying device is proposed to address these issues.

[0026] The solution is further illustrated by the following examples:

[0027] Figure 1 This is a schematic diagram of an automatic spraying device according to an embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of point A.

[0028] Please see Figure 1 and Figure 2 The automatic spraying device of this embodiment can be used to spray topcoat onto containers to protect them.

[0029] Specifically, the automatic spraying device may include a robot 10, a spray gun 20, a paint assembly 30, a cleaning assembly 40, and an atomizing assembly 50. The spray gun 20 is mounted on the robot 10, enabling the robot 10 to move the spray gun 20. The paint assembly 30, the cleaning assembly 40, and the atomizing assembly 50 are all connected to the spray gun 20 to provide paint, cleaning agent, and atomizing gas to the spray gun 20, respectively, thereby enabling the spray gun 20 to spray paint or clean itself.

[0030] In this embodiment, the robot 10 is mounted on a base surface. The base surface can be the ground, a platform, or a shelf, etc. The robot 10 is a multi-axis industrial robot, with one end of the robot 10 away from the base surface designated as a free end 11, which is movable. This allows the robot 10 to move the spray gun 20 along the path to be sprayed.

[0031] See Figure 2 The automatic spraying device may also include a laser sensor 72. The laser sensor 72 is mounted on the free end 11 and faces the spraying direction of the spray gun 20, thereby collecting spraying information.

[0032] In this embodiment, a mounting plate is provided on the free end 11, and the spray gun 20 and the laser sensor 72 are respectively disposed on the surfaces of opposite sides of the mounting plate. Meanwhile, the laser sensor 72 can be configured as a laser positioning sensor, thereby pre-collecting and planning the spraying path on the container or container door frame to be painted, so that the spray gun 20, driven by the robot 10, sprays paint onto the container or container door frame along the spraying path.

[0033] See Figure 2 The spray gun 20 is fixed to the free end 11, and thus moves under the drive of the robot 10.

[0034] In this embodiment, the spray gun 20 is provided with a spraying interface 21 and an atomizing interface 22. The spraying interface 21 is connected to both the paint assembly 30 and the cleaning assembly 40, and the atomizing interface 22 is connected to the atomizing assembly 50.

[0035] Specifically, the automatic spraying device may also include a three-way connector 71. The three-way connector 71 is provided with three interfaces. Two interfaces of the three-way connector 71 are connected to the paint assembly 30 and the cleaning assembly 40, respectively, and the other interface is connected to the spraying interface 21, so that the paint assembly 30 and the cleaning assembly 40 can be connected to the spray gun 20.

[0036] In some other embodiments, there may be two spraying ports 21, which are respectively connected to the paint assembly 30 and the cleaning assembly 40, so that the paint assembly 30 and the cleaning assembly 40 are simultaneously connected to the spray gun 20.

[0037] In this embodiment, the spray gun 20 may include a gun body 23, a needle 24, and a spray valve 25. The gun body 23 is fixed to the free end 11 and is provided with a spraying interface 21 and an atomizing interface 22. An internal cavity is provided within the gun body 23, and both the spraying interface 21 and the atomizing interface 22 are connected to this cavity. The needle 24 and the spray valve 25 are connected to the gun body 23. The needle 24 guides the paint or cleaning agent from the cavity out of the cavity and sprays the paint onto the desired spraying location. The spray valve 25 controls the opening and closing of the needle 24. Specifically, the spray valve 25 controls the needle 24 to open and close at a frequency or continuously, enabling the spray gun 20 to perform spraying or cleaning, thereby allowing the spray gun 20 to adapt to the spraying process requirements of different paints.

[0038] See Figure 1 and Figure 2 The coating assembly 30 may include a coating pipeline 31 and a coating valve 32. The coating valve 32 is disposed on the coating pipeline 31 and is used to control the opening or closing of the coating pipeline 31. One end of the coating pipeline 31 is connected to the spraying interface 21, and the other end is connected to the coating supply device, so that the coating can flow along the coating pipeline 31 to the spray gun 20.

[0039] In this embodiment, the coating assembly 30 may further include a coating pump 33 and a coating container 34. Both the coating pump 33 and the coating container 34 may be disposed on the base surface and located on the side of the robot 10. Specifically, the coating container 34 is used to store coating, and one end of the coating pump 33 is connected to the coating container 34, while the other end is connected to the coating pipeline 31, so that the coating pump 33 can drive the coating in the coating container 34 to flow along the coating pipeline 31 and provide coating to the spray gun 20.

[0040] It should be noted that the coating can be set according to the actual situation, that is, the coating can be solvent-based coating, high-solids coating, solvent-free coating, water-based coating, powder coating, etc.

[0041] See Figure 1 and Figure 2 The cleaning assembly 40 may include a cleaning pipeline 41 and a cleaning valve 42. The cleaning valve 42 is disposed on the cleaning pipeline 41 and is used to control the opening or closing of the cleaning pipeline 41. One end of the cleaning pipeline 41 is connected to the spray interface 21, and the other end is connected to the cleaning agent supply device, allowing the cleaning agent to flow along the cleaning pipeline 41 to the spray gun 20. It should be noted that the cleaning valve 42 may be configured as a solenoid valve, so as to open or close the valve by electromagnetic drive.

[0042] In this embodiment, the cleaning assembly 40 may further include a cleaning pump 43 and a cleaning agent container 44. Both the cleaning pump 43 and the cleaning agent container 44 can be disposed on the base surface and located on the side of the robot 10. The cleaning agent container 44 is used to store the cleaning agent. One end of the cleaning pump 43 is connected to the cleaning agent container 44, and the other end is connected to the cleaning pipeline 41, so as to drive the cleaning agent in the cleaning agent container 44 to flow along the cleaning pipeline 41 into the spray gun 20, thereby enabling the cleaning agent to clean the spray gun 20, ensuring the cleanliness of the internal cavity of the spray gun 20, and thus keeping the internal passage of the spray gun 20 normal.

[0043] It should be noted that the two ports of the tee connector 71 are connected to the paint pipe 31 and the cleaning pipe 41 respectively, and the other port is connected to the spraying port 21.

[0044] See Figure 1 and Figure 2 The atomizing component 50 is connected to the atomizing interface 22 to provide atomizing gas to the spray gun 20. The atomizing gas can be set to high-pressure gas, which can atomize the paint. Driven by the high-pressure gas, the paint in the paint component 30 can be sprayed out from the gun body 23 and coated on the container or container door, thereby improving the utilization efficiency of the paint.

[0045] At the same time, the atomizing gas can also atomize the cleaning agent to improve the cleaning effect of the cleaning agent on the spray gun 20.

[0046] In this embodiment, the atomizing assembly 50 may include an atomizing conduit 51 and an air source. The air source provides compressed gas and can be a high-pressure gas cylinder or compressed gas supplied by an air pump. The atomizing conduit 51 connects the air source and the atomizing interface 22 to guide the compressed gas into the spray gun 20. Furthermore, a solenoid valve is provided on the atomizing conduit 51 to control its opening or closing.

[0047] It should be noted that in actual use, the paint valve 32 and the cleaning valve 42 of the automatic spraying device can only be activated at one time. That is, when the paint valve 32 is activated, the cleaning valve 42 is deactivated, allowing the spray gun 20 to spray paint; while when the cleaning valve 42 is activated, the paint valve 32 is deactivated, allowing the cleaning agent to enter the spray gun 20 and clean it.

[0048] See Figure 2 Both the paint valve 32 and the spray valve 25 can be configured as pneumatic valves. The paint valve 32 and the spray valve 25 are connected to an air source via a drive line 60, allowing them to be opened or closed under the drive of compressed gas.

[0049] Specifically, the paint valve 32 is connected to the air source through a drive line 60, and the spray valve 25 is connected to the air source through another drive line 60, so that the air source can drive the paint valve 32 and the spray valve 25 to open or close.

[0050] Meanwhile, a solenoid valve 61 is provided on the drive line 60 to control the drive line 60 to open or close, so that the gas source can supply drive gas to the paint valve 32 or the spray valve 25 separately.

[0051] It should be noted that, in this embodiment, the air source used by the paint valve 32, the spray valve 25 and the atomizing component 50 can be set to the same air source, so that the air source can drive the paint valve 32 and the spray valve 25 to open or close, and can also provide atomizing gas to the spray gun 20.

[0052] In other embodiments, both the paint valve 32 and the spray valve 25 can be configured as solenoid valves, so that the paint valve 32 and the spray valve 25 can respectively control the opening or closing of the paint pipeline 31 and the gun needle 24. Specifically, in this embodiment, the spray valve 25 is configured as a high-frequency solenoid valve to control the opening or closing of the gun needle.

[0053] Therefore, when the automatic spraying device is spraying, it simultaneously opens the paint valve 32 and the spraying valve 25, and closes the cleaning valve 42. The robot 10 moves the spray gun 20 and the laser sensor 72, and sprays according to the pre-collected spraying path. After spraying is completed, the paint valve 32 and the spraying valve 25 are closed.

[0054] During the cleaning process, the automatic spraying device moves the spray gun 20 to the waste liquid collection point, simultaneously opening the cleaning valve 42 and the spraying valve 25, and closing the paint valve 32 to begin cleaning the spray gun 20. Cleaning is complete when the liquid sprayed from the gun body 23 no longer contains paint, and the cleaning valve 42 and the spraying valve 25 are then closed.

[0055] In summary, robot 10 is mounted on a base surface, with one end of robot 10 away from the base surface designated as a free end 11 capable of movement. Spray gun 20 is fixed to the free end 11 and can move with it, allowing it to move along the spraying path under the influence of robot 10. Paint assembly 30 includes paint piping 31 and paint valve 32, and cleaning assembly 40 includes cleaning piping 41 and cleaning valve 42. Spray gun 20 is equipped with a spraying interface 21 and an atomization interface 22. Paint piping 31 and cleaning piping 41 are connected to spray gun 20 through spraying interface 21 to supply paint and cleaning agent to spray gun 20, respectively. Atomization assembly 50 is connected to atomization interface 22 to supply atomized gas to spray gun 20, atomizing the paint and thereby improving paint utilization efficiency. Paint valve 32 and cleaning valve 42 are respectively connected to paint pipeline 31 and cleaning pipeline 41. At the same time, only one of paint valve 32 and cleaning valve 42 can be turned on, so that the spray gun 20 can spray paint under the drive of robot 10, or allow cleaning agent to enter the spray gun 20 and clean the spray gun 20, so as to ensure the accuracy and spraying effect of the spray gun 20 in the next spraying.

[0056] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
