Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying, in particular to a portable multifunctional paint construction robot. Background Art

[0002] Exterior wall coating application is a crucial component of building construction, and its overall effectiveness significantly impacts the building's quality. Wall coatings decorate and protect building walls, creating a beautiful and tidy appearance while also protecting and extending their service life.

[0003] For example, the national authorized patent announcement number CN217975242U discloses a line patrol robot for exterior wall paint spraying construction, which belongs to the field of exterior wall paint spraying technology. The robot includes a line patrol walking mechanism, a spraying mechanism mounted on the line patrol walking mechanism, and a rooftop feeding system connected to the spraying mechanism. The line patrol walking mechanism includes a steel wire rope, a walking body connected to the steel wire rope in a rolling manner, and a walking controller mounted on the walking body. The spraying mechanism includes a connecting rod connected to the walking controller, a paint storage barrel connected to the connecting rod, and a spray gun and color sensor mounted on the paint storage barrel. The rooftop feeding system includes a mobile base located on the roof, a feeding barrel mounted on the mobile base and connected to the paint storage barrel, and a master controller connected to the walking controller. This utility model uses machinery to replace manual labor for the manual spraying of exterior wall paint. This not only has high spraying efficiency and avoids slowing down the construction progress, but also has almost no construction risks.

[0004] However, the above-mentioned exterior wall paint spraying construction line patrol robot can only move and spray in the vertical direction during the exterior wall spraying process. If the lateral position needs to be adjusted, the staff needs to readjust the position of the wire rope. When the wire rope is adjusted, it will cause the spray gun to swing and rotate, which will cause uneven spraying and inconsistent coating thickness, affecting the final construction quality. Utility Model Content

[0005] The purpose of the present utility model is to provide a portable multifunctional paint construction robot to solve the problem proposed in the above-mentioned background technology that during the spraying of external walls, only vertical movement spraying can be performed. If the horizontal position needs to be adjusted, the staff needs to readjust the position of the wire rope, which affects the overall construction progress and reduces efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A portable multifunctional paint construction robot comprises: a vehicle plate, a reduction motor fixedly mounted on the upper surface of the vehicle plate, a roller fixedly mounted on one end of the output shaft of the reduction motor, a guide rail fixedly mounted on the upper surface of the vehicle plate, a lifting mechanism slidably mounted on the outer surface of the guide rail, a spraying mechanism fixedly mounted inside the lifting mechanism, so that the spraying mechanism can perform cross-directional moving spraying operations through the movement of the lifting mechanism and the roller.

[0008] Preferably, a push-pull rod is fixedly mounted on one end of the upper surface of the guide rail rod, and the upper surface of the vehicle plate between the push-pull rods can be used for workers to stand.

[0009] Preferably, a mounting plate is fixedly installed between the two groups of push-pull rods, and a camera is fixedly installed at one end of the mounting plate so that the camera is tilted downward at 30°.

[0010] Preferably, the lifting mechanism includes an H-shaped plate, in which a limiting wheel is rotatably installed. The H-shaped plate contacts both sides of the outer surface of the guide rail rod through the limiting wheel set, and a U-shaped frame is fixedly installed between the two groups of H-shaped plates.

[0011] Preferably, the U-shaped frame is fixedly connected to the movable block of the linear module, and the linear module is fixedly installed between the guide rails.

[0012] Preferably, the spraying mechanism includes a support frame, which is fixedly installed in a U-shaped frame, and a storage barrel is fixedly installed in the support frame. The lower surface of the storage barrel is connected to the spray gun, and an expansion port is fixedly installed at one end of the spray gun spray port. The upper surface of the storage barrel is connected to the ball valve, so that the storage barrel can be filled with paint through the ball valve.

[0013] Preferably, the signal transmitting end of the camera is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the reduction motor and the linear module. The camera is integrated with a visual recognition system that can identify the wall status, such as roughness and color difference, so as to accurately control the operation of the spray gun.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the design of the reduction motor, guide rod, camera, roller, lifting mechanism and spraying mechanism, when spraying the wall, the reduction motor can be started to drive the roller to rotate, and then the roller can drive the spraying mechanism in the vehicle plate to move to the end of the wall to be sprayed, and it can also be pushed and moved by pushing the push-pull rod. The mobility of the roller can facilitate transportation and operation. After the spraying mechanism is moved to the end of the wall to be sprayed, the sprayed wall can be displayed in the monitoring range of the camera, and then the camera can transmit the captured image to the controller, and then the controller can control the lifting mechanism and the reduction motor to drive the spraying mechanism to perform cross-directional mobile spraying operations. The linkage between the camera and the controller not only provides real-time wall observation capabilities, but also accurately captures the sprayed area to avoid overlap or omissions, ensuring uniform distribution of the coating.

[0016] 2. Through the design of linear module, H-shaped plate, limiting wheel, storage barrel and spray gun, after the reduction motor controls the roller to move to one end of the wall to be sprayed, the spray gun can be started to extract the paint in the storage barrel and spray it on the wall. The spraying process is within the monitoring range of the camera. Then the controller will continue to receive the real-time picture sent by the camera, and automatically calculate the spraying trajectory according to the preset spraying path or through image analysis. The controller outputs the control signal to drive the linear module and the reduction motor respectively. When the linear module is started, the limiting wheel in the H-shaped plate will be driven by the moving block to touch the outer surface of the guide rod for vertical rise, so that the H-shaped plate can drive the U-shaped frame between them to rise vertically, and the U-shaped frame will drive the spray gun in the support frame to move vertically. The gun performs a vertical upward spraying operation, and when it reaches the top, the reduction motor is started to drive the car plate to move horizontally, and then the spray gun can be driven to move horizontally to the area that has not been sprayed. Then the linear module can be started again to drive the spray gun to descend vertically, thereby realizing the cross-directional mobile spraying operation. The real-time monitoring of the camera can help the controller to obtain the image of the spraying area in time, ensure the accuracy and timely adjustment of the spraying process, and effectively reduce manual intervention. By automatically controlling the vertical and lateral movement of the spray gun, the spraying area can be switched quickly, reducing the time wasted due to manual position adjustment. By controlling the lifting and movement of the spray gun, it can ensure that the paint is evenly distributed on the wall, reducing the risk of uneven coating and omissions.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0023] like Figure 1 As shown, a portable multifunctional paint construction robot includes: a vehicle plate 1, a reduction motor 106 is fixedly mounted on the upper surface of the vehicle plate 1, a roller 105 is fixedly mounted on one end of the output shaft of the reduction motor 106, a guide rail rod 101 is fixedly mounted on the upper surface of the vehicle plate 1, a lifting mechanism 2 is slidably mounted on the outer surface of the guide rail rod 101, and a spraying mechanism 3 is fixedly mounted inside the lifting mechanism 2, so that the spraying mechanism 3 can perform a cross-directional moving spraying operation through the movement of the lifting mechanism 2 and the roller 105.

[0024] A push-pull rod 102 is fixedly mounted on one end of the upper surface of the guide rail rod 101 , and the upper surface of the vehicle plate 1 between the push-pull rods 102 can be used for workers to stand.

[0025] A mounting plate 103 is fixedly mounted between the two sets of push-pull rods 102 , and a camera 104 is fixedly mounted on one end of the mounting plate 103 , so that the camera 104 is tilted downward at 30°.

[0026] Through the design of the reduction motor 106, the guide rod 101, the camera 104, the roller 105, the lifting mechanism 2 and the spraying mechanism 3, when spraying the wall, the reduction motor 106 can be started to drive the roller 105 to rotate, and then the roller 105 can drive the spraying mechanism 3 in the vehicle plate 1 to move to the end of the wall to be sprayed, and can also be pushed and moved by pushing the push-pull rod 102. The mobility of the roller 105 can facilitate transportation and operation. After the spraying mechanism 3 is moved to the end of the wall to be sprayed, the sprayed wall can be displayed within the monitoring range of the camera 104. Then, the camera 104 can transmit the captured image to the controller, and then the controller can control the lifting mechanism 2 and the reduction motor 106 to drive the spraying mechanism 3 to perform cross-directional moving spraying operations. The linkage between the camera 104 and the controller not only provides real-time wall observation capabilities, but also accurately captures the sprayed area to avoid overlap or omission, ensuring uniform distribution of the coating.

[0027] like Figure 2-Figure 3 As shown, the lifting mechanism 2 includes an H-shaped plate 202, in which a limiting wheel 203 is rotatably installed. The H-shaped plate 202 is fitted onto both sides of the outer surface of the guide rail rod 101 through the limiting wheel 203, and a U-shaped frame 204 is fixedly installed between the two sets of H-shaped plates 202.

[0028] The U-shaped frame 204 is fixedly connected to the movable block of the linear module 201 , and the linear module 201 is fixedly installed between the guide rails 101 .

[0029] The spraying mechanism 3 includes a support frame 301, which is fixedly installed in the U-shaped frame 204. A storage barrel 302 is fixedly installed in the support frame 301. The lower surface of the storage barrel 302 is connected to the spray gun 303. An expansion port 304 is fixedly installed at one end of the spray port of the spray gun 303. A ball valve 305 is installed on the upper surface of the storage barrel 302, so that the storage barrel 302 can be filled with paint through the ball valve 305.

[0030] The signal transmitting end of the camera 104 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the reduction motor 106 and the electric control end of the linear module 201. The camera 104 is integrated with a visual recognition system that can identify the wall status, such as roughness and color difference, so as to accurately control the operation of the spray gun 303.

[0031] Through the design of the linear module 201, H-shaped plate 202, limiting wheel 203, storage barrel 302 and spray gun 303, after the reduction motor 106 controls the roller 105 to move to one end of the wall to be sprayed, the spray gun 303 can be started to extract the paint in the storage barrel 302 and spray it on the wall. During the spraying process, it is within the monitoring range of the camera 104. Then the controller will continue to receive the real-time image sent by the camera 104, and automatically calculate the spraying trajectory according to the preset spraying path or through image analysis. The controller outputs a control signal to drive the linear module 201 and the reduction motor 106 respectively. When the linear module 201 is started, the limiting wheel 203 in the H-shaped plate 202 will be driven by the moving block to touch the outer surface of the guide rod 101 for vertical ascent, thereby enabling the H-shaped plate 202 to drive the U-shaped frame 204 between them to vertically rise. The shape frame 204 will drive the spray gun 303 in the support frame 301 to perform a vertical upward spraying operation. After spraying to the top, the reduction motor 106 will be started to drive the car plate 1 to move horizontally, and then the spray gun 303 will be driven to move horizontally to the area that has not been sprayed. Then the linear module 201 can be started again to drive the spray gun 303 to descend vertically, thereby realizing the cross-directional mobile spraying operation. The real-time monitoring of the camera 104 can help the controller to obtain the image of the spraying area in time, ensure the accuracy and timely adjustment of the spraying process, and effectively reduce manual intervention. By automatically controlling the vertical and horizontal movement of the spray gun 303, the spraying area can be switched quickly, reducing the time waste caused by manual position adjustment. By controlling the lifting and movement of the spray gun 303, it can ensure that the paint is evenly distributed on the wall, reducing the risk of uneven coating and omissions.

[0032] According to the above technical solution, the working steps of this solution are summarized and sorted out: when starting work, the reduction motor 106 can be started to drive the roller 105 to rotate, and then the vehicle plate 1 can be driven to move in a straight line along the wall or the ground, and then the spray gun 303 can be driven to move to the starting position of the wall to be sprayed. The spraying range can be displayed in the camera 104, and its signal transmitting end is connected to the signal receiving end of the controller to monitor the spraying area to ensure that the spraying path is accurate. Then the controller controls the linear module 201 to drive the spray gun 303 in the support frame 301 to move vertically to the appropriate height position to start the spraying operation. Then the controller will continue to receive the camera signal. The controller receives the real-time picture sent by the camera 104 and automatically calculates the spraying trajectory according to the preset spraying path or through image analysis. The controller outputs a control signal to drive the reduction motor 106 and the linear module 201 to control the spray gun 303 in the support frame 301 to move precisely, thereby realizing the cross-directional mobile spraying operation. During the spraying process, if an obstacle is encountered or the spraying path needs to be adjusted, the controller will make corresponding adjustments based on the real-time feedback of the camera 104 to ensure the spraying quality, and the spray gun 303 completes the spraying operation of the entire wall according to the predetermined path and sequence. After completion, the robot can move to the next work area or stay in the current area.

[0033] In summary: the robot can drive the spray gun 303 to perform cross-directional mobile spraying operations, and through the linkage of the camera 104 and the controller, it not only provides real-time wall observation capabilities, but also can accurately capture the sprayed area to avoid overlap or omissions, ensuring uniform distribution of the coating.
