Description

Maintenance system and maintenance method of cloud laser processing device

The present invention relates to a maintenance system and method which can automatically monitor a laser processing machine and perform troubleshooting in time.

At present, the common laser processing technology can carry out various processing such as marking, engraving, cutting, rust removal and welding. It has multiple functions and rich materials, including wood, metal, leather, paper and other materials. The common laser processing machines on the market are divided into two main technologies: "fiber laser" and "CO2 laser", which also use high-energy beams to act on objects. The main difference lies in the wavelength of the light source. Since different materials can absorb different wavelengths of energy, it is the main factor that affects the applicable materials. If you add a rotating shaft, it can also be used for carving on curved surfaces, such as glasses and thermos. Because the laser processing machine has a wide processing range and a large processing volume, the probability of failure is also relatively increased. Therefore, the maintenance method mainly based on labor is difficult to load, and it is time-consuming and cost-consuming.

Therefore, there is a patent case of the new No. M579748 "operation panel that can connect and read the status of the machine tool" announced on June 21, 108, which is mainly used for machine tool operation and machine tool status reading. . There are two main parts. One of them is to improve the wiring method of cables and use the microprocessor to change the I/O status of the machine tool controller through ethernet network communication, so as to achieve the advantages of saving wiring, easy maintenance, and reducing costs. The second series operation panel can continuously read the machine status, such as mechanical point, spindle load, alarm status and other information. Through the wireless network, you can connect to the cloud database or ERP database for data storage, analysis, real-time monitoring and other functions.

The previous case of the patent only has the functions of monitoring faults and issuing warnings, and does not have the ability to eliminate the causes of faults. In particular, when the laser processing machine fails, a fault code will be displayed. The maintenance personnel need to carefully compare the fault causes represented by a large number of fault code data, and need personnel with rich maintenance experience, or those who have documented The detailed maintenance record table is for the maintenance personnel to search for reference, so that the fault can be eliminated according to the cause of the fault, so it is quite labor-intensive and time-consuming.

There is also a patent case of the new model No. M579748 "operation panel that can connect and read the status of machine tools" announced on June 21, 108, mainly including: a plurality of working machines, an external access device, A sensing module, a cloud monitor, a remote controller and a network server are connected to the plurality of working machines, the sensing module, the cloud monitor and the remote controller, and the cloud monitor The external access device is connected with the remote controller to achieve remote control.

The above-mentioned transmission module is a man-machine interface for manual control to output the fault signal.

The above-mentioned fault signals generate different fault codes according to different fault causes. The database stores the solutions corresponding to the fault codes. The processing module parses the fault codes, searches the database and compares them to Find this solution that matches the fault code.

The above control computer will automatically record the cause of the failure and the solution, and store it.

When the above-mentioned control computer fails to transmit the fault signal to the server, it directly inputs the fault phenomenon or the fault code by manual input through a transmission module of the monitoring unit, so as to generate the fault signal, and then output the fault signal. Fault signal to the server.

When there are more than two solutions above, one of the solutions can be manually selected and executed.

C. The monitoring unit sends the fault signal to a server in the cloud. After the monitoring unit 1 receives the fault signal output by the control computer A1, it will send the fault signal to the server 2 in the cloud. In addition, if the operator of the laser processing machine A finds that the laser processing machine 1 has a fault phenomenon, and the monitoring unit 1 does not transmit the fault signal to the server terminal 2, he can also directly use the man-machine interface. The transmission module 12 is manually input to input the fault phenomenon or fault code, thereby generating the fault signal, and then outputting the fault signal to the server 2 .
