Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying devices, in particular to a robot remote-controlled paint spraying device. Background Art

[0002] As the running part of a motor vehicle, the bogie is very susceptible to corrosion damage during operation due to the severe changes in climate and other conditions, and is often affected by rain, snow, wind, sand, flying stones, etc., as well as severe vibrations during operation. Moreover, the bogie is located at the bottom of the vehicle body, and the working environment is even worse. Under long-term outdoor operation conditions, it will be severely corroded, causing safety hazards, directly endangering the operation safety of the motor vehicle and affecting the service life of the motor vehicle. Therefore, it is necessary to spray the bogie externally to protect the bogie.

[0003] At present, the spraying of locomotive bogies is mainly completed by full manual operation. A group of three or four people use manual paint spray guns to spray the upper and lower, left and right, front and back, inside and outside of the locomotive bogies in an environment filled with paint mist, which takes about 3 hours. The main problem of this traditional and backward manual spraying operation method is that the highly dispersed paint mist and volatile solvents not only pollute the environment and are not good for human health, but also waste paint and cause economic losses. Manual spraying has a low degree of automation, is time-consuming and labor-intensive, and the quality of spraying depends entirely on the operation of the workers. It can no longer meet the needs of the intelligentization of Industry 4.0 and the increasingly high quality requirements of spraying processes. Utility Model Content

[0004] In view of the shortcomings of the prior art, such as poor working environment, backward means and poor spraying effect, the utility model provides a robot remote-controlled painting device, which has the advantages of improving the work efficiency of spraying paint on workpieces, realizing standardized operations, less-managed management, ensuring the consistency of spraying effects, greatly reducing operating costs, reducing workers' labor intensity and saving labor, improving working comfort, and optimizing the on-site working environment, especially in summer, winter, and rainy and snowy weather operations where there are safety risks such as labor safety and personal injury.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a manipulator remote-controlled paint spraying device, comprising a foundation and a control cabinet, the top of the foundation is fixedly connected to a robot track, a robot is installed on the outside of the robot track, a spray gun rack is fixedly connected to the tail of the robot, a hollow shell is fixedly connected to the outside of the robot, a paint pipe and an air pipe are fixedly connected to the inside of the hollow shell in sequence, a high-pressure mixed gas spray gun is installed inside the spray gun rack, a wear-resistant ring is installed on the outside of the high-pressure mixed gas spray gun, a safety pin is fixedly connected to the outside of the high-pressure mixed gas spray gun, and an explosion-proof solenoid valve is installed inside the high-pressure mixed gas spray gun.

[0006] Preferably, a brake release button is provided on the outside of the control cabinet, an axis is provided inside the robot, and a brake is provided on the outside of the axis. The robot adopts the Kawasaki KF264 ​​explosion-proof spray robot. All axes contain programmable software limits to limit the robot's operation overtravel. The axis can be driven to stop hard at the place where the overtravel operation may cause damage to the robot. All axis systems are equipped with braking systems. In the event of an emergency stop, error or power failure, the movement of the arm that is in full load, full extension and full speed can be stopped in a short time. When the power is removed, all brake systems are in the "ON" (in use) state by default, and the brake of the corresponding axis is manually released through the brake release button on the control cabinet.

[0007] Preferably, the main structure of the robot is arranged on a slide plate provided on the robot track, and the robot dynamically moves back and forth along the slide plate of the robot track according to the requirements of the spraying process.

[0008] Preferably, a computer is arranged on the top of the control cabinet, and a control system is arranged inside the computer for controlling the movement of the robot.

[0009] Preferably, the paint pipe is externally connected to a paint delivery mechanism to supply paint. The maximum fluid pressure of the high-pressure mixed air spray gun is 28MPa, the maximum air pressure is 0.7Mpa, the start control switch is triggered, and the trigger speed is 50-70msec (fully open-fully closed). The small and light round spray gun design can cope with extremely high production speeds, the parts are highly durable, the continuous operation time is longer, the spraying efficiency is high, and the cost is greatly saved. The modular design is easy to repair and replace, the operation is simple and reliable, and it can automatically adjust the paint flow and automatically switch the atomization fan width.

[0010] Preferably, the safety pin is externally connected to an alarm mechanism, and the alarm mechanism is used to send out an alarm signal.

[0011] Preferably, the safety pin is fixedly connected to the spray gun holder, and the device automatically stops after the safety pin breaks. The spray gun holder is used to protect the spray gun. When there is a large deviation in the position of the workpiece or the automatically called spraying program is inconsistent with the actual spraying workpiece, the spray gun collides with the workpiece, and the safety pin breaks after being stressed. The control system automatically stops after detecting the alarm signal, thereby avoiding greater damage to the spray gun and the equipment.

[0012] Beneficial effects:

[0013] 1. The robot remote control painting device can build the paint tube and air tube into the arm through the hollow shell of the robot, without exposing any pipes on the outside. The upper part of the KF264 ​​robot is a process arm for installing high-pressure mixed gas spray guns, solenoid valves and other spraying equipment, shortening the distance between the spraying equipment and the spray gun, ensuring the switching time of spraying start and stop. According to the actual situation on site, the corresponding profiling trajectory is written for the corresponding different types of locomotive bogies. The robot can realize different angles and postures of the spray gun when spraying different positions of the bogie, which improves the painting efficiency while ensuring the coverage of the workpiece surface.

[0014] 2. The robot remote control paint spraying device protects the spray gun through structures such as the spray gun holder, safety pin and wear-resistant ring. When there is a large deviation in the position of the workpiece or the automatically called spraying program is inconsistent with the actual spraying workpiece, the spray gun collides with the workpiece and the safety pin breaks after being stressed. The control system automatically stops after detecting the alarm signal to avoid greater damage to the spray gun and equipment. BRIEF DESCRIPTION OF THE DRAWINGS
