[0032] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the utility model.

[0033] like Figure 3 , Figure 4 The structure of the utility model shown is an independently controllable vacuum coating device, including a plurality of coating boxes, a display device and a PLC controller.

[0034] In order to solve the problems existing in the prior art and overcome its defects and realize the invention purpose of stable operation of vacuum coating equipment, the technical solution adopted by the utility model is:

[0035] like Figure 3 , Figure 4 As shown, the vacuum coating equipment of the utility model can be independently controlled, and each operating part thereof is connected to the PLC controller through an independent control circuit; the PLC controller controls the operation and start and stop of each operating part respectively.

[0036] The vacuum coating equipment is provided with a computer host, which is connected to a PLC controller and a display device.

[0037] After the transformation of the utility model, the original cumbersome control mode is removed, and an industrial computer is used to control the start and stop of the equipment, thereby reducing the situation of equipment downtime caused by host failure.

[0038] The number of N2 flow meters installed on the coating box is: 8 on M52 and 8 on M62.

[0039] According to the production process requirements, an N2 flow meter will be added to the original coating box, so that the equipment can add new production processes and make new products.

[0040] The vacuum coating equipment is provided with a shutdown alarm associated with the start and stop of the equipment. When the shutdown alarm sounds, the vacuum coating equipment stops running.

[0041] The vacuum coating equipment is provided with a fault alarm which is not associated with the start and stop of the equipment; when a minor fault occurs in the vacuum coating equipment, the fault alarm sends out an alarm signal which serves as a prompt.

[0042] The utility model adds an alarm light to remind employees of faults. After rewriting the program and configuration, in the new control system, some unnecessary conditions are removed according to the production line requirements, and the various parts of the equipment can be operated freely. When a fault occurs, the corresponding fault point can be found according to the alarm content and handled in time. Some alarms that are not very important will only be prompted by the alarm light. After the maintenance operator knows about it, he can handle it quickly without stopping the equipment.

[0043] The display device adopts a display screen with virtual control buttons for human-computer dialogue, and the display screen adopts a Chinese interface.

[0044] The alarm records are now in Chinese, and the alarm information is described more clearly, allowing staff to find the problem more quickly;

[0045] The PLC controller stores the control programs of all points of the equipment, including the exhaust, transmission, heating and power supply parts.

[0046] Software: All points of the equipment are reorganized, and programs are written separately for the exhaust, transmission, heating, power supply, etc. The original equipment functions are modified as required to make it more convenient for operators to operate on the computer configuration.

[0047] Equipment debugging: Let the system automatically run the driving test to complete the signal handshake between the coating equipment and the peripheral Mengli equipment. Correct and adjust the problems in time to ensure that the entire equipment system can meet production requirements.

[0048] The key technical points of this utility model are:

[0049] The equipment can be operated stably in automatic operation, and each part of the equipment can be controlled independently. If a part of the equipment has a problem, it will not interfere with the other parts and affect the overall operation of the equipment.

[0050] The original equipment has many interlocking conditions. After shutdown, there will always be abnormal startup. It is often necessary to find the corresponding missing signal in the program to run it, which is extremely inconvenient.

[0051] The utility model retains some important interlocking functions, and some unnecessary parts have been removed. If a fault occurs, the maintenance personnel only need to find the problem according to the alarm record to deal with it.

[0052] In summary, the beneficial effects achieved by the utility model are:

[0053] 1. According to the requirements of the production line, the alarm is revised to solve the problems that cause some functions to stop, such as the lack of target cooling water, and the corresponding power supply is directly shut down;

[0054] 2. Rewrite the heating program and use professional temperature control function blocks to control heating. After setting, the temperature is relatively stable.

[0055] 3. Split the original integrated control and cancel some unnecessary interlocking signals, which makes it more convenient for employees to operate and can find problems more quickly when they occur.

[0056] The specific operating state of the vacuum coating equipment of the utility model is as follows Figure 5 to Figure 7 shown.

[0057] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
