Description

Technical Field

[0001] The utility model relates to the field of chemical vapor deposition, and particularly to a coating machine with a coating baffle having a flipping function. Background Art

[0002] Coating equipment uses a certain heating and evaporation method to evaporate a coating material and turn it into a gas, and the particles fly to the surface of a substrate and condense into a film.

[0003] As Figure 1 shown Figure 1 shows the schematic diagram of existing vapor deposition equipment. For example, F1 is a coating roller, and a film serving as a substrate is wound around the coating roller F1. Currently, it is necessary to coat a layer of aluminum on the film. F3 is a crucible, and the aluminum material is in the crucible F3. After heating the aluminum material to an evaporating state, the aluminum material flies to the film and condenses into a coating layer of aluminum material on the film.

[0004] In the coating equipment, there are many components. In order to prevent the aluminum material from flying onto these components, a baffle F4 is usually selected to block the aluminum material from coating the above-mentioned components. The area of the baffle F4 corresponding to the coating roller F1 is designed with an opening F2, and the aluminum material then enters the film.

[0005] During vapor deposition, it is inevitable that the coating vapor condenses on the coating roller F1. When cleaning the coating roller F1, the baffle F4 needs to be removed. In the coating equipment, the baffle F4 is fixed by bolts, and moreover, the baffle F4 is large and heavy. It is necessary to use equipment to lift the baffle F4 away in order to further remove and clean the coating roller F1. However, this removal method of the baffle F4 makes the steps of cleaning the coating roller F1 become cumbersome. Summary of the Utility Model

[0006] To solve the above problems, the utility model provides a coating machine with a coating baffle having a flipping function. The flipping assembly method can reduce the steps of removing bolts and simplify the steps of cleaning the coating roller.

[0007] To achieve the above object, the technical solution adopted by the utility model is: a coating machine with a coating baffle having a flipping function. The film transmission part thereof includes a cover plate that shields the peripheral area of the coating roller. It is characterized in that the film transmission part further includes a flipping device, which is composed of a motor, a worm and worm gear mechanism, and a driven shaft. The cover plate is sleeved on the driven shaft, and the motor drives the driven shaft to rotate through the worm and worm gear mechanism, so that the cover plate follows the driven shaft and unfolds the peripheral area of the coating roller.

[0008] Furthermore, an opening is provided on the cover plate, and the opening has a size corresponding to the coating roller. The coating roller is exposed to the coating vapor through the opening.

[0009] Furthermore, a heat-conducting fluid for heat transfer is provided inside the cover plate to carry away the heat flow on the cover plate.

[0010] Furthermore, the cover plate is arc-shaped, and the cooling channels provided inside the cover plate are used to guide the heat-conducting fluid to fill the inside of the cover plate. The cover plate includes an inner cover and an outer cover. The cooling water channels include a first pipe, a second pipe, and a plurality of baffles. The partition plates are arranged in the cavity of the outer cover to divide the cavity into continuous and winding channels. The first pipe and the second pipe are respectively connected to both ends of the channel and are respectively fixed on the inner surface of the cavity and the inner cover.

[0011] Furthermore, there is also a cooling plate adapted to the circumferential surface of the coating roller. The cooling plates located inside the film transmission part are close to both ends of the coating roller. Heat dissipation channels are provided inside the cooling plates, and the heat-conducting fluid inside the heat dissipation channels carries away the heat.

[0012] Advantages of the present utility model:

[0013] The coating machine of the present utility model adopts a baffle with a flipping function. The baffle uses a flipping mechanism. Through the flipping mechanism, it is not necessary to detach from the film transmission part. Relying on the motor, the worm and worm gear mechanism, and the driven shaft, the cover plate performs a flipping action on the film transmission part, thereby opening the peripheral area of the film transmission part corresponding to the coating roller. Thus, it is possible to remove the coating roller inside the film transmission part without removing the baffle, thereby simplifying the steps of cleaning the coating roller and making the cleaning of the coating roller easier.

[0022] Figure 2 This is the coating machine of the present utility model. In this coating machine, the film transmission part 1 is shown. The film transmission part 1 is used to guide the movement of the film. At the lower end of the film transmission part 1, there is a cover plate 1a with an opening. Inside the film transmission part, there is a coating roller 1b corresponding to the above opening. The film is wound around the coating roller 1b. After the aluminum material is evaporated by heating, it passes through the opening and condenses on the film. Under the rotation of the coating roller 1b, the film is dragged to move on the coating roller 1b, so that each area of the film can be coated with an aluminum film.

[0023] As Figure 2-4 shown, in this embodiment, the common use of the cover plate 1a and the outer shell 2 wraps the transmission components inside the film transmission part 1 to prevent the aluminum vapor from flowing onto the transmission components. The cover plate 1a is equivalent to a flippable part of the outer shell 2. The outer shell 2 is also provided with a flipping device 3. The flipping device 3 is used to drive the cover plate 1a to flip. After flipping, the cover plate 1a exposes the transmission components belonging to the lower end of the film transmission part 1, and performs a removal process on the exposed coating roller 1b. This exposure includes both ends of the coating roller 1b and the components connected to the above two ends.

[0024] As Figure 5-7 shown, the flipping device 3 is composed of a worm and worm gear mechanism 31, a motor 32, and a driven shaft 33. The cover plate 1a is sleeved on the driven shaft 33 and rotates following the rotation of the driven shaft 33. The motor 32 drives the driven shaft 33 to rotate through the worm and worm gear mechanism 31. This design scheme mainly meets the basic use in the film transmission part 1, that is, it does not affect the basic use of the film transmission part 1 and does not make a change in principle to the transmission components.

[0025] There is a heat-conducting fluid inside the cover plate 1a. Since the heating temperature of the crucible can reach 1300 °C, while the temperature of the cover plate 1a is between 500 - 600 °C, the heat-conducting fluid reduces the influence of heat on the film and avoids the film from being baked at high temperature for a long time.

[0026] The cover plate 1a is in an outwardly convex arc shape. In order to ensure that the heat-conducting fluid fills the entire interior of the cover plate 1a, a cooling channel is provided inside the cover plate 1a. The cover plate 1a includes two parts, an inner cover 100 - a and an outer cover 100 - b. The cooling water channel includes a first pipe 100 - c, a second pipe 100 - d, and a plurality of partition plates 100 - e. The partition plates 100 - e are arranged in the cavity of the outer cover 100 - b, dividing the above cavity into continuous and winding channels 100 - f. The first pipe 100 - c and the second pipe 100 - d are respectively connected to both ends of the channel 100 - f. After the inner cover 100 - a seals the cavity, the heat-conducting fluid can only flow from one end of the channel 100 - f to the other end. Among them, the end of the channel 100 - f for discharging the heat-conducting fluid is located at the end of the outer arc surface of the cover plate 1a (as Figure 8As shown, in other words, after the heat-conducting fluid is poured in, the end for discharging the heat-conducting fluid is located at the highest point of the channel 100-f. In this embodiment, the first pipe 100-c guides the heat-conducting fluid to flow into the channel 100-f, and the second pipe 100-d discharges the heat-conducting fluid in the channel 100-f. The first pipe 100-c and the second pipe 100-d are respectively fixed on the inner surface of the cavity and the inner cover 100-a. Only after the entire channel 100-f is completely filled, the heat-conducting fluid will be discharged from the second pipe 100-d as the water level rises.

[0027] Therefore, the design of the partition 100-e, the first pipe 100-c, and the second pipe 100-d is determined based on the state of the cover plate 1a during use. The advantage of this design is that it can allow the heat-conducting fluid to fully contact the cover plate 1a and take away the heat.

[0028] As Figure 3 shown, in the transmission assembly, there is also a cooling plate 4. The cooling plate 4 has a shape adapted to the circumferential surface of the coating roller 1b. The cooling plate 4 is close to both ends of the coating roller 1b. A heat dissipation channel is provided in the cooling plate 4, and the heat-conducting fluid in the heat dissipation channel takes away the heat. The cooling plate 4 is used to dissipate the heat of the transfer film. There is a gap between the cooling plate 4 and the coating roller 1b, and the film is located in the gap. When the coating roller 1b drags the film to move, the film will contact the cooling plate 4, and the heat is taken away by the heat-conducting fluid.

[0029] It should be noted that the above heat-conducting fluid can be water or other liquid refrigerants.

[0030] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
