Description

Technical Field

[0001] This utility model relates to the field of coating devices, and in particular to an interior wall coating application robot that prevents paint spillage. Background Technology

[0002] With the accelerating pace of urbanization, the development and utilization of underground space continues to expand, leading to a surge in underground structures such as underground parking lots, underground commercial complexes, and civil defense projects. Basement interior wall coating construction, as a crucial step in ensuring the aesthetics, durability, and functionality of building spaces, directly impacts the user experience and maintenance costs of underground spaces through its quality and efficiency.

[0003] In large-scale basement interior wall painting, painting robots are used to increase construction efficiency. These robots mainly consist of a robotic arm, a spraying system, a control system, a material supply system, and a sensor system. The robotic arm, acting as the actuator, has multiple degrees of freedom and can flexibly adjust the spraying position and angle. The spraying system, including nozzles and spray guns, is responsible for atomizing the paint and spraying it onto the target surface. The control system receives instructions and controls the robotic arm's movement trajectory and spraying parameters. The material supply system ensures a stable supply of paint. The sensor system monitors the spraying environment, distance, paint flow rate, and other information in real time, feeding this feedback to the control system for precise adjustment.

[0004] Existing pneumatic spray nozzle painting robots have problems. When the air pressure supply stops, the paint remaining inside the nozzle lacks an active recovery mechanism. Furthermore, the paint delivery pipeline is usually designed as a straight-through system. When the device stops spraying, the paint in the pipeline is prone to overflow from the nozzle due to inertia, resulting in a large amount of paint dripping onto the ground, causing pollution and safety risks. Therefore, an interior wall painting robot that prevents paint spillage is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an interior wall coating application robot that prevents paint spillage. It aims to improve the problem in the prior art that "when a traditional pneumatic spray nozzle coating robot stops spraying, the paint in the pipeline is prone to overflow from the nozzle due to inertia and drip onto the ground, causing pollution and safety risks."

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an interior wall paint application robot for preventing paint spillage, comprising a mobile base and a robotic arm, wherein the robotic arm is fixedly installed on the front side of the mobile base, a nozzle is fixedly connected to the output end of the robotic arm, a delivery pipe is connected to the inner wall of the nozzle, and a collection component is fixedly installed on the outer side of the nozzle through a support component;

[0007] The collection assembly includes a connector, which is fixedly connected to the outside of the support assembly. A base plate is fixedly connected to the lower part of the connector, and a collection box is provided on the upper part of the base plate. Sliding fasteners are provided on both the left and right sides of the inner wall of the connector. Springs are provided on the inner walls of the two sets of fasteners on opposite sides. An insertion hole is provided on the inner wall of the collection box near the connector, and the fastener is inserted into the inner wall of the insertion hole. Two sets of limiting rails are fixedly connected to the rear side of the connector. Insert plates are slidably connected to the inner walls of the limiting rails, and the lower parts of the insert plates are inserted into the outside of the two sets of fasteners.

[0008] As a further description of the above technical solution: the support assembly includes a support cylinder a, which is inserted into the outside of the nozzle. A bearing is sleeved on the outer wall of the support cylinder a. A support cylinder b is sleeved on the front outer side of the support cylinder a. A set screw is threaded to the front inner wall of the support cylinder b. The lower side of the set screw passes through the support cylinder a and is threaded to the inner wall of the nozzle.

[0009] As a further description of the above technical solution: the upper part of the connector is configured as a ring.

[0010] As a further description of the above technical solution: the rear diameter of the support cylinder a is larger than the front diameter.

[0011] As a further description of the above technical solution: the rear diameter of the support cylinder b is larger than the front diameter.

[0012] As a further description of the above technical solution: the rear diameter of the support cylinder a and the support cylinder b is smaller than the upper inner diameter of the connecting piece.

[0013] As a further description of the above technical solution: a protrusion is provided on the inner side of the support cylinder b, and the protrusion on the inner side of the support cylinder b is inserted into the inner wall of the support cylinder a.

[0014] As a further description of the above technical solution: the lower inner side of the connector is fixedly connected to the outer side of the bearing.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a collection component on the outside of the nozzle, when the nozzle stops spraying, the paint remaining inside or the paint overflowing due to sudden changes in pipeline pressure will drip directly into the collection box, avoiding dripping onto the ground, keeping the construction environment clean, and eliminating the safety hazards caused by slippery ground. At the same time, the collection box is connected to the connector through snap-fit ​​parts, springs and insert plates, which is easy to disassemble and can be quickly removed for cleaning without affecting the continuous operation of the device, thus ensuring construction efficiency.

[0017] 2. In this utility model, by using the support component, the nozzle is driven by the robotic arm, and the connecting part is connected to the bearing. Under the influence of gravity, the collection box can always maintain a vertical state with the nozzle, ensuring that the dripping paint falls accurately into the box. At the same time, the rear sides of the support cylinder a and support cylinder b form a baffle, reducing the paint contact with the bearing, so that the bearing can still maintain stable operation in the harsh underground environment and reduce the frequency of equipment maintenance.

[0024] 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.

[0025] Reference Figures 1-3This utility model provides an embodiment of an interior wall coating application robot that prevents paint spillage. It includes a mobile base 1 and a robotic arm 2, serving as the support and moving carrier for the entire device. It has a built-in battery and lifting mechanism, and an external control panel to control the lifting mechanism and robotic arm 2. It also features a drive system, enabling the device to move freely within a basement, adapting to different construction locations. The robot's speed and direction can be adjusted according to ground conditions. The robotic arm 2 is fixedly mounted on the front of the mobile base 1 and connected to the lifting mechanism, which drives it up and down. A nozzle 4 is fixedly connected to the output end of the robotic arm 2, atomizing or evenly spraying the paint supplied by the delivery pipe 3 to form a uniform coating on the wall surface, directly affecting the coating quality and effect. The inner wall of the nozzle 4 is connected to the delivery pipe 3, connecting the supply system to the nozzle 4, ensuring a stable supply of paint from the supply box during spraying. A collection component 5 is fixedly installed on the outside of the nozzle 4 via a support assembly 6 to collect dripping paint during spraying, solving the paint dripping problem.

[0026] Reference Figures 2-4 The collecting component 5 includes a connector 51. The upper part of the connector 51 is ring-shaped and is fixedly connected to the outside of the support component 6, serving to connect the support component 6 and the collecting component 5. The lower part of the connector 51 is fixedly connected to a base plate 52, which provides an installation support platform for the collecting box 53 and ensures the stability of the collecting box 53. The upper part is provided with a positioning pin to assist in fixing the collecting box 53. The collecting box 53 is set on the upper part of the base plate 52 and is the main container for collecting dripping paint. When the nozzle 4 stops spraying, the residual or overflowing paint drips into the collecting box 53, avoiding pollution of the ground. The inner walls of the connector 51 are slidably connected with snap-fit ​​pieces 54 on both the left and right sides. The inner walls of the two sets of snap-fit ​​pieces 54 on opposite sides are provided with springs 55. When the collecting box 53 is installed, the snap-fit ​​pieces 54 are inserted into the insertion holes 56 of the collecting box 53 to achieve snap-fit ​​fixation between the collecting box 53 and the connector 51. When disassembling, the snap-fit ​​pieces 54 are squeezed to disengage them from the insertion holes 56, which facilitates the quick disassembly and cleaning of the collecting box 53.

[0027] Reference Figure 3 and Figure 4 The collection box 53 has an insertion hole 56 on its inner wall near the connector 51. The snap-fit ​​component 54 is inserted into the inner wall of the insertion hole 56. Two sets of limiting rails 57 are fixedly connected to the rear side of the connector 51. The limiting rails 57 are U-shaped and are used to fix the insert plate 58. The insert plate 58 is slidably connected to the inner wall of the limiting rails 57. The insert plate 58 is T-shaped and serves to lock the snap-fit ​​component 54 to prevent the snap-fit ​​component 54 from sliding accidentally during operation and to ensure the firmness of the collection box 53 installation. The lower part of the insert plate 58 is inserted into the outer side of the two sets of snap-fit ​​components 54.

[0028] Reference Figure 1 and Figure 2 The support assembly 6 includes a support cylinder a61, which is inserted into the outside of the nozzle 4 to support the bearing 62. The bearing 62 is sleeved on the outer wall of the support cylinder a61. The lower inner side of the connector 51 is fixedly connected to the outside of the bearing 62 to reduce friction. When the nozzle 4 moves, the collection assembly 5 is kept perpendicular to the nozzle 4 by the bearing 62 under the action of gravity, ensuring that the collection box 53 is always facing the bottom of the nozzle 4. The support cylinder b63 is sleeved on the outer front side of the support cylinder a61 and contacts the inner ring of the bearing 62 at the rear side, which can axially limit the bearing 62.

[0029] Reference Figure 2 A set screw 64 is threaded onto the inner wall of the front side of the support cylinder b63. ​​The lower side of the set screw 64 passes through the support cylinder a61 and is threaded onto the inner wall of the nozzle 4. The position of the support cylinder a61 and the support cylinder b63 is fixed by the set screw 64. At the same time, the support cylinder a61 and the support cylinder b63 are fixedly installed on the nozzle 4. The rear diameter of the support cylinder a61 is larger than the front diameter, and the rear diameter of the support cylinder b63 is larger than the front diameter. The rear diameters of the support cylinders a61 and b63 are smaller than the upper inner diameter of the connector 51. This is used to block the paint and reduce the impact of the paint on the bearing 62. A protrusion is provided on the inner side of the support cylinder b63. ​​The protrusion on the inner side of the support cylinder b63 is inserted into the inner wall of the support cylinder a61 to facilitate the alignment of the positions of the support cylinders a61 and b63.

[0030] Working principle: During use, the device enters the underground construction area by carrying the robotic arm 2 and the nozzle 4 on the mobile base 1. After the control system is started, the robotic arm 2 moves the nozzle 4 according to the preset program or the real-time planned path. The delivery pipe 3 delivers the paint in the supply system to the nozzle 4 to complete the wall spraying. During or after the spraying process, the collection component 5 and the support component 6 work together to solve the problem of paint dripping and ensure the stable operation of the equipment.

[0031] When the nozzle 4 stops spraying, the dripping paint will fall directly into the collection box 53. The collection component 5 is connected to the bearing 62 of the support component 6 via the connector 51. Under the action of gravity, the collection box 53 always maintains a vertical downward posture. No matter how the nozzle 4 moves, the collection box 53 is always facing directly below the nozzle 4, ensuring accurate recovery of dripping paint and avoiding contamination of the ground or wall.

[0032] The collection box 53 is connected to the connector 51 via a snap-fit ​​connector 54: the spring 55 pushes the snap-fit ​​connector 54 into the insertion hole 56 of the collection box 53 to achieve fixation; when disassembling, slide the insert plate 58 upward to disengage from the outside of the snap-fit ​​connector 54, squeeze the snap-fit ​​connector 54 to retract it, squeeze the spring 55, and the collection box 53 can be removed for cleaning, supporting "replacement when full" without affecting the continuous operation of the device.

[0033] Both support cylinders a61 and b63 are designed with a stepped structure where the rear diameter is larger than the front diameter. The rear sides of the two are combined to form an annular baffle, which prevents impurities such as mud and dust in the underground environment from directly contacting the bearing 62, ensuring the smooth operation of the bearing 62 for a long time. When the bearing 62 needs maintenance, the limiting position of support cylinders a61 and b63 can be quickly released by rotating the set screw 64, and the support cylinders a61 and b63 can be removed from the outside of the nozzle 4 for easy maintenance of the bearing 62.

[0034] Finally, it should be noted that components not described in detail herein are existing technologies. The above descriptions are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
