[0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. Spray guns are often used in the spraying industry and can be directly filled with paint. As the spraying process becomes more and more intelligent, spray guns are often used in conjunction with robots, that is, the spraying process of the spray gun is controlled by a spray control system. That is, a simple spray gun can be installed in automated equipment, such as automatic glue spraying machines, automatic glue coating machines, automatic paint spraying machines, coating machines and other spraying equipment.

[0003] Currently, the spray gun is controlled by adjusting the atomization and fan shape of the spray gun through the control cabinet and the teach pendant, but it cannot be maintained stably, the continuity is poor and the data cannot be monitored. When an abnormality occurs, it is impossible to detect and adjust it in time, resulting in process waste and cost loss.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] A monitoring and control system for a spray gun fan shape and atomization amount of the present invention comprises:

[0033] A control cabinet 1 is connected to a PC control terminal 3 via a compiler 2. The control cabinet 1 is equipped with a display screen 4 and a spray gun 5. The spray gun 5 has a fan-shaped output pipe 501 and an atomization output pipe 502.

[0034] A signal transmission module 6 is disposed in the control cabinet 1 and is signal-connected to the PC control terminal 3;

[0035] The sensing module 7 can collect the paint output of the spray gun 5 in real time and transmit the data to the signal transmission module 6 and then reach the PC control terminal 3, forming a closed-loop system through data compilation and collection.

[0036] As a further introduction to this embodiment, the signal transmission module 6 includes a program signal encoder 601 connected to the PC control terminal 3, which is used for signal conversion, and can convert an analog signal into a digital signal or convert one digital signal into another digital signal. This signal conversion can make the signal easier to process or transmit, and can also improve the quality and stability of the signal.

[0037] The signal is connected to the communication signal encoder 602 of the PC control terminal 3. The reliability and stability of signal transmission are improved by the communication signal encoder 602. By adding redundant information (i.e., supervisory code element or check bit) in the information sequence, the receiving end can detect and correct errors caused by noise, interference or other factors in the transmission process. There is a specific association rule between this redundant information and the information code element. Once an error occurs in the transmission, this rule will be destroyed, so that it will be detected and corrected by the receiving end. In addition, through channel coding, the bit error rate of the communication system can be significantly reduced, the ability of the receiver to identify errors is improved, and the quality of the recovered information is improved. This is of great significance for ensuring the stability and reliability of the communication system.

[0038] The signal is connected to the pressure sensing encoder 603 of the PC control terminal 3, which can convert the data transmitted by the sensing module 7 into an electrical signal.

In actual use, the paint is stored in the paint container 9 and output to the spray gun 5 through the air pipe 8, and the PC control terminal 3 selects to use the fan-shaped output pipe 501 or the atomization output pipe 502 after data analysis.

[0040] As a further introduction to this embodiment, the fan-shaped output pipe 501 is provided with a first valve 5011 , and the atomization output pipe 502 is provided with a second valve 5021 . The opening and closing of the first valve 5011 and the second valve 5021 are both controlled by the PC control terminal 3 .

[0041] As a further introduction to this embodiment, the sensing module 7 includes a paint output detector 701 connected to the PC control terminal 3 by signal; and

[0042] A first pressure sensor 702, which is used to detect the pressure of the fan-shaped output pipe 501 and form a pressure detection signal to the signal transmission module 6;

[0043] The second pressure sensor 703 is used to monitor the pressure of the atomization output pipe 502 and generate a pressure detection signal to the signal transmission module 6 .

[0044] In the above technical solution, the monitoring and control system of the spray gun fan shape and atomization amount provided by the present invention has the following beneficial effects:

[0045] A monitoring and control system for the fan shape and atomization amount of a spray gun of the present invention effectively improves the reliability and stability of data transmission by arranging a program signal encoder, a communication signal encoder and a pressure sensing encoder; a paint output amount detector is used in conjunction with two pressure sensors to monitor the data of the fan output pipe and the atomization output pipe in real time, and the data is transmitted to the PC control terminal, effectively avoiding batch losses and cost consumption after abnormal problems occur.
