Description

Technical Field

[0001] The utility model relates to the technical field of vacuum extraction and pressing of aluminum-plated films, in particular to a device used for a vacuum extraction and pressing machine of aluminum-plated films. Background Art

[0002] Aluminum film vacuum extraction is to place the film substrate to be plated in a vacuum evaporator and use a vacuum pump to evacuate the film. Common vacuum pumps include Roots vacuum pumps. In order to increase the ultimate vacuum degree of the pump, Roots pumps can be used in series. The working principle of Roots pumps is similar to that of Roots blowers. Due to the continuous rotation of the rotor, the pumped gas is sucked from the air inlet into the space v0 between the rotor and the pump casing, and then discharged through the exhaust port.

[0003] According to the application number 201922482793.6, a device for a vacuum extraction and pressing machine for aluminum-plated films is disclosed.

[0026] By providing the shock absorbing assembly 3, a double buffering effect can be achieved when the vacuum pump 4 generates vibration during operation, thereby improving the stability of the vacuum pump 4 and preventing noise caused by vibration.

[0027] See also Figure 3 The sleeve 301 is fixedly connected to the inner bottom of the base 1, the sliding rod 302 is slidably connected to the inside of the sleeve 301, and the top of the sliding rod 302 is fixedly connected to the protective cover 2, the movable plate 303 is fixedly connected to the bottom end of the sliding rod 302, the buffer spring 304 is sleeved on the surface of the sliding rod 302, the sponge 305 is arranged at the inner bottom of the sleeve 301, the limiting groove 306 is opened on the two side surfaces of the sleeve 301, the limiting slider 307 is fixedly connected to the two sides of the movable plate 303, the top of the buffer spring 304 is fixedly connected to the inner wall of the sleeve 301, the bottom end of the buffer spring 304 is fixedly connected to the movable plate 303, vacuum pumps 4 are installed at both ends of the interior of the protective cover 2, an exhaust pipe 5 is installed in series between the two vacuum pumps 4, and an exhaust port 8 is fixedly installed on one side surface of the protective cover 2;

[0028] When the vacuum pump 4 generates vibration during operation, the force caused by the vibration drives the slide rod 302 and the movable plate 303 to move up and down, so that the buffer spring 304 is subjected to compression deformation. The compression deformation of the buffer spring 304 absorbs the force driven by the vibration, thereby achieving a shock-absorbing and buffering effect. In addition, the sponge body 305 can absorb the remaining impact force, thereby achieving a double buffering effect.

[0029] See also Figure 2 and Figure 4A heat dissipation component 6 is arranged inside the protective cover 2, and the heat dissipation component 6 includes a heat dissipation pipe 601, a connecting pipe 602, a temperature sensor 603, a water pump 604 and a tubular cooler 605. The heat dissipation pipes 601 are fixedly connected to the surfaces of both sides of the protective cover 2, and the heat dissipation pipes 601 are provided with coolant inside. The bottom ends of the two heat dissipation pipes 601 are fixedly connected with the connecting pipes 602, and the temperature sensor 603 is fixedly installed inside one of the heat dissipation pipes 601. A water pump 604 is fixedly installed on the upper surface of the protective cover 2, and the input end of the water pump 604 is fixedly connected to the top of one of the heat dissipation pipes 601, and the output end of the water pump 604 is fixedly connected to the tubular cooler 605, and the tubular cooler 605 is fixedly connected to the top of the other heat dissipation pipe 601. A controller 7 is fixedly installed on the surface of one side of the protective cover 2, and the controller 7 is electrically connected to the water pump 604 and the tubular cooler 605;

[0030] The specific model of the tubular cooler 605 is a GLC type cooler, which uses copper finned tubes for heat dissipation. In conjunction with the temperature sensor 603, the controller 7, and the water pump 604, the coolant with excessively high temperature can be sucked into the tubular cooler 605 for cooling, and then flow back into the heat dissipation tube 601 after cooling, thereby ensuring the heat dissipation effect of the heat dissipation tube 601.

[0031] In the utility model, the working steps of the device are as follows:

[0032] The first step: connect one end of the exhaust pipe 5 to the coating machine. When the coating machine is running, the two vacuum pumps 4 are used to evacuate the machine to increase the efficiency of vacuuming. When the vacuum pump 4 generates vibration during operation, the force driven by the vibration is transmitted to the protective cover 2, so that the protective cover 2 is forced to move up and down, and at the same time, the sliding rod 302 and the movable plate 303 are driven to move up and down, so that the buffer spring 304 is forced to compress and deform. The compression deformation of the buffer spring 304 absorbs the force driven by the vibration, which has the effect of shock absorption and buffering. In addition, the sponge 305 can absorb the remaining impact force, which has the effect of double buffering, effectively improving the stability of the vacuum pump 4. At the same time, when the movable plate 303 moves, it can drive the limit slider 307 to slide in the limit groove 306, so that its movement is more stable.

[0033] The second step: when the vacuum pump 4 continuously works and generates a large amount of heat energy, heat exchange is performed through the coolant inside the heat pipe 601 to absorb the generated heat and achieve the effect of heat dissipation. Water cooling is used for heat dissipation, and the heat dissipation efficiency is higher. When the coolant in the heat pipe 601 continuously absorbs heat and causes its own temperature to rise, the coolant temperature is detected by the temperature sensor 603. When it exceeds the set range, the temperature sensor 603 sends a signal, and the controller 7 receives the signal and starts the water pump 604 and the tubular cooler 605 to suck the coolant with too high temperature into the tubular cooler 605 for cooling. After cooling, it flows back into the heat pipe 601 to ensure the heat dissipation effect of the heat pipe 601.
