Description

Technical Field

[0001] This utility model relates to the field of optical thin film technology, and in particular to an automatic coating machine device for multilayer optical thin films. Background Technology

[0002] In the field of optical thin film technology, multilayer optical thin films are widely used in the fabrication of various optical devices due to their specific optical properties (such as precise refractive index, reflectivity, and transmittance). As a key piece of equipment in the fabrication of multilayer optical thin films, the operational stability, coating accuracy, and equipment lifespan of automated coating machines directly affect the quality of the thin films and production efficiency.

[0003] When existing devices are used, the light source used in the coating process generates a lot of heat during operation. If the heat cannot be dissipated in time, it will not only cause the internal components of the light source to age faster and degrade in performance due to high temperature, but may also cause short circuits, burnout and other malfunctions, affecting the stability of the light source output and thus interfering with the coating process. Therefore, we propose an automatic coating machine for multilayer optical thin films to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide an automatic coating machine for multilayer optical thin films, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic coating machine for multilayer optical thin films includes a shock-absorbing component, an mounting component mounted on the upper part of the shock-absorbing component, a coating component mounted inside the shock-absorbing component, a heat dissipation component mounted inside the shock-absorbing component, and a dust removal component mounted inside the shock-absorbing component.

[0007] Preferably, the shock absorption assembly includes a housing, with dampers installed at the four lower corners of the housing, and connecting legs installed at the lower ends of the four dampers.

[0008] Preferably, the mounting assembly includes a mounting plate, which is mounted on the upper end of the housing. The upper end of the mounting plate is fixedly connected to the cover by bolts, and a vacuum tube is mounted on the upper end of the housing.

[0009] Preferably, the coating assembly includes a partition plate, the partition plate is installed in the inner cavity of the housing, a wave lamp is installed on the inner surface of the partition plate, and a placement shell is installed in the inner cavity of the housing.

[0010] Preferably, the heat dissipation assembly includes a fan, which is installed in the inner cavity of the housing. A heat dissipation fan shell is installed in the inner cavity of the housing. A connecting pipe is installed at the left and right ends of the heat dissipation fan shell. Several fixing plates are installed on the outer surface of the connecting pipe.

[0011] Preferably, the dust removal assembly includes a second fixing plate. Several second fixing plates are installed on the inner surface of the right side of the connecting pipe. The ends of the several second fixing plates near the center are rotatably connected to a turbine. A pulley is installed on the outer surface of the turbine. Two third fixing plates are installed at the lower end of the outer shell. A pulley is installed on the right end of the third fixing plate located on the left side. A belt is wound around the outer surface of the pulley and the outer surface of the pulley. A reciprocating screw is installed on the right end of the pulley. Two guide rods are installed at the ends of the two third fixing plates that are close to each other. A scraper is slidably connected to the outer surfaces of the two guide rods and the outer surface of the reciprocating screw.

[0012] Preferably, all of the aforementioned fixing plates are fixedly connected to the bottom wall of the inner cavity of the outer shell, and a filter plate is installed in the inner cavity of the outer shell.

[0013] Preferably, the right end of the reciprocating lead screw is rotatably connected to the right end of the fixed plate located on the left.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device achieves vibration reduction during use through its designed damping and mounting components. When the device is running, significant vibrations may cause slight changes in the relative position of the coating target and the substrate, or result in uneven deposition of evaporated sputtered particles on the substrate surface. The damper effectively reduces this vibration, ensuring the stability of the relative positions of the components during the coating process. This guarantees accurate and uniform film thickness, improving the optical performance of multilayer optical films, such as refractive index, reflectivity, and transmittance, to better meet design requirements. Simultaneously, the vibrations generated during equipment operation produce noise. Prolonged exposure to noise can negatively impact the health of operators. The damper reduces the noise generated by equipment vibration, improving the working environment in the workshop, protecting the hearing of operators, and enhancing work comfort.

[0016] 2. This device, through its designed heat dissipation and dust removal components, can achieve vibration reduction during the operation of the wave lamp. Wave lamps typically generate a large amount of heat during operation. If this heat accumulates and cannot be dissipated in time, it may cause internal components to age faster due to high temperatures, experience performance degradation, or even short circuits and burnout. By controlling the heat dissipation, the operating temperature of the wave lamp can be kept within a reasonable range, avoiding a decrease in light source stability due to overheating. This ensures that the output energy or light parameters remain stable, providing reliable light source conditions for the coating process. At the same time, it reduces the wear and tear on the internal components of the wave lamp caused by high temperatures, significantly extending its service life, reducing replacement frequency, and lowering equipment maintenance costs and downtime. Moreover, when the wave lamp is in a high-temperature state for a long time, it not only poses a risk of failure itself but may also conduct heat to other components of the coating machine, triggering a chain of failures.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 As shown, an automatic coating machine for multilayer optical thin films includes a shock-absorbing component 1, an mounting component 2 mounted on the upper part of the shock-absorbing component 1, a coating component 3 mounted inside the shock-absorbing component 1, a heat dissipation component 4 mounted inside the shock-absorbing component 1, and a dust removal component 5 mounted inside the shock-absorbing component 1.

[0026] When implementing this solution, the operator connects the installation component 2 to the vacuum pump, then places the lens to be coated into the shock-absorbing component 1, and then places the coating material into the coating component 3. The coating material is heated, and the operator starts the coating component 3 to perform the coating, thus achieving the coating effect on the lens. At the same time, the shock-absorbing component 1 will dampen the device during the coating process to prevent any movement that could affect the coating.

[0027] Meanwhile, when using the coating component 3, the operator activates the heat dissipation component 4 to dissipate heat from the coating component 3, preventing damage to the coating component 3 due to overheating. At the same time, the air generated by the heat dissipation component 4 will also cause the dust removal component 5 to rotate, thereby allowing the dust removal component 5 to scrape away the dust on the filter plate, preventing dust from clogging the filter plate and also preventing the problem of bacteria growth caused by dust remaining on the filter plate for a long time.

[0028] Specifically, in order to reduce vibration during coating, such as Figure 2 and Figure 4 As shown, in this scheme, the shock absorption component 1 includes a housing 11, and dampers 12 are installed at the four corners of the lower end of the housing 11. Connecting legs 13 are installed at the lower ends of the four dampers 12.

[0029] For further details, please refer to [link / reference]. Figure 1 and Figure 3 The mounting assembly 2 includes a mounting plate 21, which is mounted on the upper end of the housing 11. The upper end of the mounting plate 21 is fixedly connected to the cover 22 by bolts, and a vacuum tube 23 is installed on the upper end of the housing 11.

[0030] For further details, please refer to [link / reference]. Figure 3 The coating assembly 3 includes a partition plate 31, which is installed in the inner cavity of the housing 11. A wave lamp 32 is installed on the inner surface of the partition plate 31, and a placement shell 33 is installed in the inner cavity of the housing 11.

[0031] In this process, the operator connects the vacuum tube 23 to the vacuum pump, then places the lens to be coated into the housing 11, and then places the coating material into the placement housing 33, which heats the coating material. At the same time, the operator turns on the wave lamp 32 to perform the coating, thus achieving the coating effect on the lens. Meanwhile, the damper 12 will reduce vibration of the device during the coating process to prevent movement that could affect the coating.

[0032] Example 2: This example improves the heat dissipation of the wave lamp 32 based on Example 1.

[0033] Specifically, in order to dissipate heat from the wave lamp 32, such as Figure 4 and Figure 5As shown, in this solution, the heat dissipation component 4 includes a fan 41, which is installed in the inner cavity of the outer casing 11. A heat dissipation fan shell 42 is installed in the inner cavity of the outer casing 11. A connecting pipe 43 is installed on the left and right ends of the heat dissipation fan shell 42. Several fixing plates 44 are installed on the outer surface of the connecting pipe 43.

[0034] For further details, please refer to [link / reference]. Figure 6 The dust removal assembly 5 includes a second fixing plate 51. Several second fixing plates 51 are installed on the inner right side of the connecting pipe 43. The ends of several second fixing plates 51 near the center are rotatably connected to a turbine 52. A pulley 53 is installed on the outer surface of the turbine 52. Two third fixing plates 54 are installed at the lower end of the outer casing 11. A pulley 55 is installed on the right end of the third fixing plate 54 located on the left side. A belt 56 is wound around the outer surface of the pulley 55 and the outer surface of the pulley 53. A reciprocating screw 57 is installed on the right end of the pulley 55. Two guide rods 58 are installed at the ends of the two third fixing plates 54 that are close to each other. A scraper 59 is slidably connected to the outer surface of the two guide rods 58 and the outer surface of the reciprocating screw 57.

[0035] For further details, please refer to [link / reference]. Figure 4 Several fixing plates 44 are fixedly connected to the bottom wall of the inner cavity of the outer shell 11, and a filter plate is installed in the inner cavity of the outer shell 11.

[0036] For further details, please refer to [link / reference]. Figure 6 The right end of the reciprocating screw 57 is rotatably connected to the right end of the fixed plate 3 54 located on the left.

[0037] When implementing this solution, while using the wave lamp 32, the operator starts the fan 41 to generate air. The air flows from the heat dissipation housing 42 to the connecting pipe 43, and finally exits from the connecting pipe 43 to dissipate heat from the wave lamp 32, preventing damage to the wave lamp 32 due to overheating. At the same time, the air generated by the fan 41 also causes the turbine 52 to rotate, which in turn causes the pulley 53, pulley 55, belt 56, and reciprocating screw 57 to rotate. This causes the scraper 59 to slide on the guide rod 58, allowing the scraper 59 to scrape away dust from the filter plate, preventing dust from clogging the filter plate and avoiding the problem of bacteria growth caused by dust remaining on the filter plate for a long time.

[0038] There is a clip inside the hole of scraper 59, which can slide in the groove of reciprocating lead screw 57.

[0039] In summary, the implementation process of this utility model is as follows:

[0040] The operator connects the vacuum tube 23 to the vacuum pump, then places the lens to be coated into the housing 11, and then places the coating material into the placement housing 33, allowing the placement housing 33 to heat the coating material. At the same time, the operator turns on the wave lamp 32 to perform coating, achieving the coating effect on the lens. Meanwhile, during the coating process, the damper 12 will reduce the vibration of the device to prevent movement during the coating process and avoid affecting the coating.

[0041] Simultaneously, when using the wave lamp 32, the operator starts the fan 41 to generate air, which flows from the heat dissipation housing 42 to the connecting pipe 43, and finally exits from the connecting pipe 43 to dissipate heat from the wave lamp 32, preventing damage to the wave lamp 32 due to overheating. At the same time, the air generated by the fan 41 also causes the turbine 52 to rotate, which in turn causes pulley 53, pulley 55, belt 56, and reciprocating screw 57 to rotate, thereby causing the scraper 59 to slide on the guide rod 58, allowing the scraper 59 to scrape away dust from the filter plate, preventing dust from clogging the filter plate and also preventing the problem of bacteria growth caused by dust remaining on the filter plate for a long time.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the fan 41 and other components used in this utility model are all conventional designs, and will not be described in detail in this utility model.
