1. The working track range of the painting robot
When selecting a painting robot, it is necessary to ensure that the working range of the robot must completely cover the relevant surface or cavity of the coated workpiece. In the case of intermittent conveying work, the painting robot sprays the delicate workpiece, such as not covering the relevant surface or cavity of the coated workpiece. In the intermittent conveying work, the robot sprays the stationary workpiece. If the coating is not completely covered, the external rail of the robot needs to be added to expand the working range.
2, the repeatability of the painting robot
For the glue application robot, the repeatability requirement is high, generally it needs to reach 0.5mm. For painting robots, the repeatability requirements are relatively low. At present, the painting robots of major companies can meet the general requirements, such as Rongde's painting robot.
3. The speed and acceleration of the robot
The larger the maximum moving speed or the maximum acceleration speed of the painting robot, the shorter the idle travel time of the robot, and the longer the absolute working time of the painting robot under a certain beat, the higher the utilization rate of the painting robot. It should be pointed out that the speed of the robot is adapted. During the spraying operation, the speed of the spraying tool is directly related to the characteristics and materials of the spraying tool, and needs to be set according to the process requirements. In addition, since the technical index of the painting robot is related to its price, it is necessary to select a robot with a high price ratio according to the production scale according to the production scale.
4, the maximum load that the robot arm can withstand
Depending on the spray application, the spray guns used in the painting or gluing process, etc., determine the maximum load on the robot arm. Sometimes in the process of spraying small workpieces, the paint is also used to lift small workpieces for transfer work. When considering the robot arm load, this factor should be taken into account.
The price of the painting robot is different. The following are the prices of the most sold painting robots that Xiaobian found in Alibaba. However, this price is for reference only and pricing is based on actual conditions.
From the above price we can see that the lowest number of painting robots is 10,000, and the highest is 100,000. The price difference is still so large. Therefore, it is best to choose according to your needs.
Such expensive painting robots are definitely going to be used for a long time. How should they be maintained?
Maintenance and precautions for the painting robotIn order to ensure the normal operation of the painting robot, relevant personnel should timely clean and maintain the equipment used.
Equipment that needs to be cleaned includes: robot body, robot track, cup selection, robot control cabinet, system control cabinet, online tracking system, vehicle identification system, vehicle input system, safety light barrier, emergency stop button box and travel switch.
1. Cleaning of the robot protective cover
The cleaning frequency of the robot protective cover needs to be determined according to the actual use of the site. The arm protective cover is closer to the rotating cup spraying area, which is easy to be contaminated. It is recommended to clean and replace it every day. The protective cover of the body is far away from the spraying area of ​​the rotating cup, which can be appropriately reduced. Number of cleaning and replacement.
The robot protective cover is a consumable item with a service life and needs to be replaced regularly and in time according to the actual use.
2, robot body cleaning
The cleaning of the robot body mainly includes the wrist part of the robot, the part below the J1 axis and other parts that are not protected by the protective cover.
(1) Cleaning of the wrist
Due to the flexible rotation of the painting robot wrist, frequent high-speed rotation is required during the spraying process, so there is no protective cover for protection, and regular cleaning is required according to actual use conditions.
(2) Cleaning of parts below the J1 axis and other parts that are not protected by the protective cover.
These parts are lightly contaminated by the paint compared to the wrist, and can be cleaned once a day according to the actual situation.
(3) Tools needed for cleaning
Clean the rag, solvent or alcohol.
(4) Cleaning method
Use a clean cloth to remove a small amount of solvent or alcohol, wipe the area to be cleaned, and then dry with a dry cloth.
It is strictly forbidden to pour solvent or alcohol directly onto the robot to prevent the solvent from penetrating into the inside of the robot body, resulting in equipment damage.
(5) Notes
Cleaning and maintenance personnel should pay attention to safety and strictly follow the standard procedures to avoid personal injury or equipment damage. It is strictly forbidden to place any sundries in the robot's working range, especially on the robot track, to avoid accidents and equipment damage.
Robot track cleaning
The daily cleaning of the robot track is very important. Once the track is too polluted or piled up, it will cause damage to the track rack or the robot body motor.
(1) Track cleaning
Since the orbital robot moves frequently on the track during the working process, timely cleaning of the track is particularly important. According to the actual use, it is recommended to clean each shift once.
(2) Tools needed for cleaning
Clean rag, solvent or alcohol, brush.
(3) Cleaning method
Use a brush to clean dust, paint, etc. in the track groove, then use a clean cloth to remove a small amount of solvent or alcohol, wipe the area to be cleaned, and then dry it with a dry cloth. It is strictly forbidden to pour solvent or alcohol directly onto the track or robot to prevent the solvent from penetrating into the inside of the robot body, resulting in equipment damage. After cleaning, all tools are packed and it is strictly forbidden to place any items on the robot track.
(4) Notes
Cleaning and maintenance personnel should pay attention to safety and strictly follow the standard procedures to avoid personal injury or equipment damage. It is strictly forbidden to place any debris in the working range of the robot, especially on the track, to avoid accidents.
