Since the paint shop is a major flammable and explosive prevention site, the spraying robot must be safe and reliable before it can be used in the paint shop. In the process of daily use of paint shop robots, some failures will cause production stagnation and losses. Among them, the high-pressure alarm failure of the spraying robot accounts for about 60%. Therefore, it is possible to prevent and solve high-voltage alarm failures, and to greatly reduce production downtime and economic losses caused by robots. Next, Songle Robot will share with you the reasons and solutions for the high-pressure alarm of the spraying robot.

1. Hardware damage causes high pressure alarm of spraying robot

As long as any hardware of the high-voltage generator controller, high-voltage generator and high-voltage line is damaged, an alarm will be given. The processing is relatively simple, and the robot can repair and replace the corresponding hardware.

Because paint is also conductive, it is generally stipulated that the distance between the atomizer and the robot body to be repaired is 25cm. In the actual production process, imperfect maintenance of the robot's profiling program and the deviation of the body fixture may cause the body and The spin cup is too close.

耀彩网3. High pressure alarm of spraying robot caused by solvent and paint leakage

Robot spraying is controlled by valves, and these valves need to be opened and closed thousands of times a day. The valves of spraying robots generally need to be replaced after opening and closing 100,000 times. Otherwise, it is easy to cause paint and solvent leakage due to damage to the robot maintenance valve. Therefore, in normal maintenance, the number of valve use times should be counted, and the valves that have reached the life of the spraying robot should be inspected in time, and if they are found to be defective, they should be replaced in time.

耀彩网Fourth, the color-changing module and the aging of the pipeline cause the spraying and there is still a shortage of high-pressure alarms

With the aging of the spraying robot, the robot maintenance and flushing program set by the manufacturer can no longer clean the color-changing module and pipeline, and the high-pressure alarm will gradually increase. We need to improve from two aspects: robot maintenance optimizes the flushing program, and extends the flushing time as much as possible without affecting the pitch; establishing a long flushing program, repeats the pipeline and color-changing module when starting up and shutting down Clean.

耀彩网Fifth, the unreasonable use of hot and cold water causes high pressure alarm of the spraying robot

耀彩网The spraying robot is very sensitive to temperature and humidity. If the ambient temperature is too low or too high, a high-pressure alarm will be generated. If the hot water and chilled water are turned on for 24 hours, the spraying robot can always maintain the robot under normal humidity and temperature, which is the most effective for the robot. Okay, but this energy consumption is relatively high, so we have to switch the cold and hot water appropriately, the following is a simple analysis of the reasonable application of hot water:

耀彩网The hot water control is mainly in winter. The hot water is turned on for 24 hours. This is a serious waste. However, if it is not turned off during production, and then turned on when production starts, the temperature difference between the robot body and the BOOTH robot maintenance is too large, resulting in The spraying robot body produces condensed water, which makes the robot frequent high-pressure alarms. According to the experience of the robot repairing the Lingang paint workshop, the hot water of the air conditioner is turned on 2h earlier to avoid this problem, which not only saves energy, but also ensures the normality of the spraying robot. the work.

耀彩网Six, other conditions cause high-pressure alarm of the spraying robot

Such as wind balance, humidity, etc. When the wind balance is not good, the paint mist may fly in one direction, and the paint mist is conductive. When too much paint mist gathers around the robot atomizer robot maintenance, it is easy to generate a high-voltage alarm of the spraying robot.
