[0059] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0060] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0061] The main solution of the embodiment of the present application is: detecting the temperature of the heat sink; when the temperature of the heat sink exceeds a preset temperature, starting the water pump, fan and servo motor; calculating the heat dissipation efficiency data of the heat sink through a preset model; adjusting the speed of the water pump, fan and servo motor according to the heat dissipation efficiency data; and dissipating the heat from the vacuum coating machine cavity through the water pump and fan with adjusted speed.

[0062] In this embodiment, for the convenience of description, the following description is made by taking the identification of the internal actuator of the vacuum coating machine cavity cooling system as the execution subject.

[0063] Since the heat dissipation of vacuum coating machines in the prior art mostly adopts natural cooling, the effect is poor, and untimely cooling can easily lead to overheating of the vacuum coating machine.

[0064] The present application provides a solution, which uses a water pump and a fan to enhance the water cooling and air cooling effects to dissipate heat from the vacuum coating machine cavity, thereby improving the heat dissipation effect of the vacuum coating machine.

[0065] It can be seen from the above embodiments that the present application uses a water pump and a fan to enhance the water cooling and air cooling effects to dissipate the heat from the vacuum coating machine cavity, thereby solving the technical problems that the existing vacuum coating machines mostly use natural cooling for heat dissipation, which has poor effects, untimely cooling, and easily leads to overheating of the vacuum coating machine, thereby achieving the goal of improving the heat dissipation effect of the vacuum coating machine.

[0066] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes the internal actuator of the vacuum coating machine cavity cooling system as an example to illustrate this embodiment and the following embodiments.

[0067] Based on this, the embodiment of the present application provides a vacuum coating machine cavity cooling method, referring to Figure 1 , Figure 1 This is a schematic flow chart of the first embodiment of the vacuum coating machine chamber cooling method of the present application.

[0068] In this embodiment, the method is applied to a vacuum coating machine cooling device, which includes: a servo motor, a water tank, a fan, a screw, a slider, a water pump and a heat sink, wherein the screw is connected to the servo motor, and the slider is connected to the screw and the fan; the vacuum coating machine cavity cooling method includes steps S10 to S50:

[0069] Step S10, detecting the temperature of the heat sink.

[0070] It should be noted that the main function of the heat sink in the vacuum coating machine is to improve the heat conduction efficiency and accelerate the heat dissipation by increasing the heat dissipation area. It is usually made of materials with high thermal conductivity, such as copper, aluminum, etc. These materials can effectively conduct heat from the heat source to the surface of the heat sink, and then dissipate the heat. The heat sink is connected to the water tank, absorbs the heat in the water tank and dissipates it.

[0071] In addition, it should be noted that the vacuum coating machine is a technical device that deposits thin films in a specific vacuum environment. It deposits metals, non-metals or other materials from the vapor phase onto the surface of the substrate by physical or chemical methods. Figure 2 A schematic structural diagram of a coating machine cavity cooling device combined with a vacuum coating machine is provided, specifically: a servo motor 1, a first water pipe 2, a first water pump 3, a heat dissipation water tank 4, a fan 5, a mounting frame 6, a spring 7, a leg 8, a screw 9, a support block 10, a heat sink 11, a second water pump 12, a coating machine body 13, a second water pipe 14, a control box 15, a slider 16, a roller 17, and a base plate 18.

[0072] Step S20, when the temperature of the heat sink exceeds a preset temperature, starting the water pump, the fan and the servo motor.

[0073] It should be noted that the preset temperature is the maximum temperature of the heat sink to ensure the normal operation of the vacuum coating machine, such as 80°C. When the heat sink temperature exceeds the preset temperature, the working state of the vacuum coating machine will be affected; the water pump is a mechanical device for conveying liquid media, used to accelerate the circulation of liquid in the water tank; the fan is a device for generating airflow, widely used in home, industrial and commercial environments to provide ventilation, cooling or air circulation, and used to accelerate the flow of air on the surface of the water tank and the heat sink; the servo motor is an engine that controls the operation of mechanical elements in a servo system. It can accurately control speed and position, and has very high position accuracy. It is used to control the up and down movement of the fan through a screw and a slider to further accelerate the flow of air on the surface of the water tank and the heat sink.

[0074] Step S30, calculating the heat dissipation efficiency data of the heat sink through a preset model.

[0075] It should be noted that the preset model is a model for calculating the heat dissipation efficiency of the heat sink through the rotation speed of the water pump and the fan, such as a finite element analysis (FEA) model, a thermal fluid analysis model, and the like.

[0076] Step S40, adjusting the rotation speeds of the water pump, the fan and the servo motor according to the heat dissipation efficiency data.

[0077] The speeds of the water pump, fan and servo motor are adjusted accordingly according to the heat dissipation efficiency data. When the heat dissipation efficiency is low, the speeds of the water pump, fan and servo motor are adaptively increased to improve the heat dissipation efficiency. When the heat dissipation efficiency is high, the speeds of the water pump, fan and servo motor are adaptively maintained or reduced to save power and electricity.

[0078] Step S50, dissipating heat from the vacuum coating machine cavity through a water pump and a fan with adjusted speed.

[0079] The speed-adjustable water pump and fan accelerate the flow of liquid in the water tank and the flow of air between the water tank and the surface of the heat sink, and dissipate heat through water cooling and air cooling.

[0080] The present embodiment provides a method for cooling the cavity of a vacuum coating machine. By using a water pump and a fan to enhance the water cooling and air cooling effects, the vacuum coating machine cavity is dissipated with heat. This solves the technical problem that the existing vacuum coating machine heat dissipation mostly uses natural cooling, the effect is poor, the cooling is not timely, and it is easy to cause the vacuum coating machine to overheat, thereby improving the heat dissipation effect of the vacuum coating machine.

[0081] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following.

[0085] Step S311, obtaining historical temperature data of the heat sink.

[0086] The historical temperature data of the heat sink can be obtained from the historical maintenance files of the vacuum coating machine to calculate the heat absorption efficiency.

[0087] Step S312, obtaining the heat absorption efficiency of the heat sink through a preset algorithm according to the historical temperature data.

[0088] It should be noted that the preset algorithm is an algorithm for calculating the heat absorption efficiency of the heat sink, which can be a BP neural network model, a simple average method (SA), an entropy value method (EV), etc.

[0089] Based on the historical temperature data of the heat sink, the heating rate of the heat sink absorbing heat and the temperature change curve are calculated.

[0090] The heat absorption efficiency is calculated through the historical temperature of the heat sink, providing a data basis for model calculations.

[0091] Step S32, obtaining the rotation speeds of the water pump and the fan.

[0092] In a specific implementation, the rotation speed of the water pump and the fan can be directly detected or calculated through a rotation speed sensor. After the rotation speed is obtained, the rotation speed can be recorded to facilitate subsequent calculation of the heat dissipation efficiency data.

[0093] Step S33, inputting the heat sink temperature, the heat absorption efficiency and the rotation speed into a preset model.

[0094] The heat sink temperature, heat absorption efficiency, and current speeds of the water pump and fan are input into the preset model for calculation.

[0095] Step S34, obtaining the heat dissipation efficiency data of the heat sink through the preset model.

[0096] It should be noted that the heat dissipation efficiency of the heat sink is the efficiency of the heat sink in releasing heat. The heat dissipation efficiency data include heat dissipation speed, temperature change curve, liquid heat dissipation speed and gas heat dissipation speed. Heat dissipation speed = heat dissipation fin temperature change difference / detection time, liquid heat dissipation speed = liquid temperature change difference / detection time, gas heat dissipation speed = heat dissipation speed - liquid heat dissipation speed.

Figure 4 , step S40 includes steps S41 to S43:

[0099] Step S41, obtaining liquid heat dissipation data and gas heat dissipation data in the heat dissipation efficiency data.

[0100] It should be noted that the liquid heat dissipation data refers to the data of the heat sink dissipating heat through the liquid in the connected water tank; the gas heat dissipation data refers to the data of the heat sink dissipating heat through the air.

[0101] Step S42, obtaining water pump adjustment data, fan adjustment data and motor adjustment data according to the liquid heat dissipation data and the gas heat dissipation data.

[0102] The heat dissipation efficiency of the liquid and the gas is obtained according to the liquid heat dissipation data and the gas heat dissipation data, and the adjustment data of the rotation speed of the water pump, the fan and the servo motor are obtained. When the heat dissipation efficiency is low, the rotation speed is adaptively increased, and when the heat dissipation efficiency is high, the rotation speed is adaptively maintained or reduced.

[0103] Step S43, adjusting the rotation speeds of the water pump, the fan and the servo motor according to the water pump adjustment data, the fan adjustment data and the motor adjustment data.

[0104] According to the adjustment data of the water pump, the fan and the servo motor, the speed of the water pump, the fan and the servo motor is adjusted accordingly.

[0107] Step S51, controlling the water pump after the speed adjustment to dissipate heat from the vacuum coating machine cavity through liquid.
