Description

Technical Field

[0001] The utility model belongs to the technical field of spin coating equipment, and particularly relates to a spin coater. Background Art

[0002] In the processing and production of lenses, different dielectric layers need to be coated on the lenses to meet actual requirements. For example, a color-changing layer is a common functional coating applied to the surface of lenses. It can automatically change color according to the light intensity to adjust the light transmittance under different light conditions and provide better visual comfort.

[0003] In the prior art, a spin coater is usually used to complete the coating process of the lens dielectric layer. Upward spin coating is a common spin coating method. In this method, the lens is usually arranged above the spray head of the spraying device. During spin coating, the lens is first adsorbed and fixed by an adsorption device, then the lens is driven close to the spraying device, and then the spraying device sprays the coating towards the lens located above it. Finally, the lens is driven to rotate and the coating of the dielectric layer on the lens surface is completed by centrifugal force. In upward spin coating, since the adsorption device and the spraying device are arranged up and down and approach and move away from each other, the feeding and discharging space of the lens is relatively small, which is inconvenient for operation.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a spin coater. Summary of the Utility Model

Detailed Embodiments

[0029] To enable those skilled in the art to better understand the technical solutions in this utility model, the following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this utility model without creative efforts shall fall within the protection scope of this utility model.

[0030] Referring to Figure 1 and Figure 2 , a spin coater in an embodiment of this utility model includes a workbench 1, a first bracket 2, a second bracket 3, an adsorption assembly 4, a spraying assembly 5, and a rotating assembly (not shown in the figure).

[0031] Referring to Figure 1 and Figure 2 , the first bracket 2 can be driven to switch between a first position and a second position. In this embodiment, the first bracket 2 is slidably connected to the workbench 1, and the first bracket 2 slides on the surface of the workbench 1 to switch between the first position and the second position. The sliding direction can be seen in the Figure 4 X direction in. The adsorption assembly 4 is used to adsorb and fix the lens and is installed on the first bracket 2.

[0032] Referring to Figure 2 , the second bracket 3 can be driven to move in a direction perpendicular to the surface where the workbench 1 is located, and the spraying assembly 5 is installed on the second bracket 3. The spraying assembly 5 is installed in cooperation with the position of the adsorption assembly 4.

[0033] Among them, when the first bracket 2 is driven to the first position, the adsorption assembly 4 is aligned directly above the spraying assembly 5. At this time, the lens on the adsorption assembly 4 can be spin-coated by the spraying assembly 5. When the first bracket 2 is driven to the second position, the adsorption assembly 4 and the spraying assembly 5 are arranged in a staggered manner so that the adsorption assembly 4 has a loading and unloading space. At this time, it is convenient to install the lens on the adsorption assembly 4 or take out the spin-coated lens from the adsorption assembly 4.

[0034] In this embodiment, when the first bracket 2 is driven to the first position, the second bracket 3 is simultaneously driven to a third position close to the adsorption assembly 4; when the first bracket 2 is driven to the second position, the second bracket 3 is simultaneously driven to a fourth position away from the adsorption assembly 4. It should be noted that in this embodiment Figures 1-4 the states where the first bracket 2 is in the first position and the second bracket 3 is in the third position are shown.

[0035] Referring to Figure 2 and Figure 3, the adsorption assembly 4 includes a cover body 41 mounted on the first bracket 2 and an adsorption head mounted at the center of the cover body 41. The adsorption head is used to connect to a vacuum device, so that vacuum adsorption of the lens can be completed. The spraying assembly 5 includes a cylinder body 51 mounted on the second bracket 3 and a spraying head mounted inside the cylinder body 51. The spraying head is used to communicate with a pump component to suck the coating material to the spraying head.

[0036] When the cover body 41 is cooperatively covered on the cylinder body 51, the first bracket 2 is located at the first position and the second bracket 3 is located at the third position. During spraying, the spraying head sprays the coating material towards the lens adsorbed on the adsorption head, and at the same time, the lens is driven to rotate by the rotating assembly, so as to complete the coating of the lens by means of centrifugal force. Among them, since the rotating assembly is a common structure in the art, it will not be elaborated here.

[0037] It can be understood that since a relatively closed spin coating space is formed after the cover body 41 covers the cylinder body 51, sputtering of the coating material can be reduced during the upward spin coating process, and at the same time, the coating material can be recycled in an organized manner through the cylinder body 51 for multiple cycles of use, reducing production costs.

[0038] Refer to Figure 2 and Figure 4 , in this embodiment, the spin coater further includes a first driving assembly 6 for driving the first bracket 2 to switch between the first position and the second position, and a second driving assembly 7 for driving the second bracket 3 to switch between the third position and the fourth position.

[0039] Refer to Figure 4 , the first driving assembly 6 includes a first driving member 61 mounted on the workbench 1 and a slide rail 62 mounted on the workbench 1. The first bracket 2 is slidably connected to the slide rail 62, and the first driving member 61 drives the first bracket 2 to move along the extension direction of the slide rail 62 to the first position or the second position. Among them, the first bracket 2 moves along Figure 4 the X direction in

[0040] Figure 2 Figure 3 and , the second driving assembly 7 includes a second driving member mounted on one side of the workbench 1 and a driving screw 71 fixed to the output end of the second driving member. The second bracket 3 is threadedly connected to the driving screw 71 to drive the second bracket 3 to move to the third position or the fourth position. Among them, the second driving member is arranged below the workbench and is not shown in the figure. In this embodiment, the second driving member can be selected as a servo motor.

[0041] Further, the second driving assembly 7 further includes a guiding seat and a guiding rod 72. The guiding seat is fixedly installed on the workbench 1. One end of the guiding rod 72 is fixedly connected to the second bracket 3, and the other end passes through and slides in the guiding seat. The axis of the guiding rod 72 is perpendicular to the surface of the workbench 1. By providing the guiding rod 72, the stability of the second driving member driving the second bracket 3 to move and switch between the third position and the fourth position can be improved.

[0042] Referring Figure 1 , in this embodiment, the spin coater further includes a loading assembly 8, an unloading assembly 9, and a conveyor belt 10. When the first bracket 2 is driven to the second position, the loading assembly 8 places the lens on the adsorption assembly 4, or the unloading assembly 9 removes the lens from the adsorption assembly 4. The conveyor belt 10 is used to convey the lens, and the loading assembly 8 obtains the lens from the conveyor belt 10. In this embodiment, the loading assembly 8 and the unloading assembly 9 can select the same equipment and are cooperatively selected with the same sliding track. Among them, since the loading assembly 8 and the unloading assembly 9 are common equipment in the art, the structure thereof will not be described in detail here.

[0043] Referring Figure 1 and Figure 2 , in this embodiment, the first bracket 2 is provided with at least two groups of adsorption assemblies 4, and the corresponding second bracket 3 is provided with spraying assemblies 5 corresponding to the number of adsorption assemblies 4 on the first bracket 2. At least two first brackets 2 are arranged in parallel, and the number of second brackets 3 is correspondingly arranged with that of the first brackets 2. By adjusting the number of the first bracket 2, the second bracket 3, the adsorption assembly 4, and the spraying assembly 5, the coating work of the lens can be completed at multiple stations at one time, so that the coating efficiency of the lens can be effectively improved.

[0044] The implementation principle of the spin coater of the present utility model is as follows:

[0045] During loading, the conveyor belt 10 conveys the lens to the material taking end of the loading assembly 8, and then the loading assembly 8 obtains the lens from the conveyor belt 10. At the same time, the first driving assembly 6 drives the first bracket 2 to move to the second position, and the second driving assembly 7 drives the second bracket 3 to move to the fourth position. Finally, the loading assembly 8 moves to the position corresponding to the adsorption assembly 4 to install the lens on the adsorption assembly 4 to complete the loading.

[0046] During coating, the first driving assembly 6 drives the first bracket 2 to move to the first position, and the second driving assembly 7 drives the second bracket 3 to move to the third position. At this time, the cover body 41 covers the cylinder body 51. Then the rotating assembly drives the lens to rotate, and at the same time, the coating material is sprayed onto the lens through the spraying head to complete the coating.

[0047] When blanking, the first driving component 6 drives the first bracket 2 to move to the second position again, and the second driving component 7 drives the second bracket 3 to move to the fourth position again. At this time, the blanking component 9 moves to the position corresponding to the adsorption component 4 and takes the lens from the adsorption component 4 to complete blanking.

[0048] When the spin coater of the present utility model is loading and unloading materials, the first bracket 2 moves to the second position, so that the adsorption component 4 and the spraying component 5 are arranged in a staggered manner, thus forming a loading and unloading space convenient for taking and placing the lens, so as to reduce the interference that the position of the spraying component 5 may cause to the loading and unloading of the lens, and effectively improve the coating efficiency of the lens.

[0049] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed claims.

[0050] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
