Description

Technical Field

[0001] This utility model relates to the technical field of automotive lens processing equipment, and in particular to a vacuum device for ultraviolet coating of automotive lenses. Background Technology

[0002] Vacuum coating technology plays a crucial role in contemporary science and industry, especially in fields such as optics, electronics, and materials science. The vacuum coating machine, as the core equipment of this technology, is mainly used to form thin films on the surface of objects to improve their physical, chemical, or optical properties. Traditional vacuum coating machines typically include heating mechanisms, vacuum mechanisms, and electrical control mechanisms, such as the lens UV coating equipment disclosed in Chinese Patent Publication No. CN213266677U.

[0003] The working principle of traditional vacuum coating machines is mainly to evaporate the components on the surface of the target material in the form of atomic clusters or ions in a vacuum environment using vacuum ion evaporation. Then, these atomic clusters or ions are deposited on the surface of the substrate (such as a lens) to form a thin film. However, the chamber needs to be heated during the coating process, which will cause the gas temperature in the chamber to rise. When the vacuum pump evacuates and directly discharges these high-temperature gases, it will greatly affect the working environment.

[0004] Therefore, in order to improve the operational applicability of existing vacuum devices, we propose a vehicle-mounted ultraviolet coating vacuum device for lenses. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the significant impact on the working environment when vacuum pumps directly discharge these high-temperature gases, thus providing a vacuum device for ultraviolet coating of vehicle-mounted lenses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a vacuum device for ultraviolet coating of automotive lenses, including a vacuum pump, wherein the input end of the vacuum pump is connected to the coating device through an input pipe, and a cooling mechanism is connected to the output end of the vacuum pump.

[0008] The cooling mechanism includes an outer tube, which is detachably connected to the output end of the vacuum pump via a flange structure;

[0009] A spiral water pipe is placed inside the outer tube, and both ends of the spiral water pipe extend to the outside of the outer tube and are connected to the water cooling circulation assembly.

[0010] Furthermore, a middle tube is fixedly connected to the inner side of the outer tube by an outer bracket, and an inner tube is fixedly connected to the inner side of the middle tube by an inner bracket. An outer channel is formed between the outer tube and the middle tube, and an inner channel is formed between the middle tube and the inner tube.

[0011] The outer channel and the inner channel are connected.

[0012] Furthermore, the spiral water pipe is wound around the outside of the inner pipe and located inside the middle pipe, with both ends of the spiral water pipe passing through the middle pipe and the outer pipe in sequence.

[0013] Furthermore, it also includes a plug, which is threaded to the end of the outer tube, and the end face of the plug is provided with a plurality of vent holes, which are connected to the outer channel.

[0014] Furthermore, the inner end of the plug abuts against and seals the end of the middle tube, and the end of the inner tube and the plug are at a predetermined distance apart.

[0015] Furthermore, the outer end of the inner tube is inserted into the output port of the vacuum pump, and a sealing gasket is fixedly installed on the outside of the inner tube to seal the connection between the inner tube and the output port of the vacuum pump.

[0016] Furthermore, the input pipe has a deformable section in the middle.

[0017] The present invention provides a vacuum device for ultraviolet coating of vehicle lenses, which has the following advantages: In this invention, a cooling mechanism is connected to the output end of the vacuum pump. Since the coating device generates high temperatures after the reaction, the cooling mechanism cools the exhaust gas during reciprocating operation, thus ensuring the comfort of the working environment. In addition, the cooling mechanism in this invention adopts a multi-channel and multiple cooling method, which can greatly improve the cooling effect on the gas. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 As one embodiment of this utility model, it discloses a vacuum device for ultraviolet coating of vehicle lenses. Specifically, the vacuum device includes a vacuum pump 1. The input end of the vacuum pump 1 is connected to the coating device through an input pipe 2. A cooling mechanism 3 is connected to the output end of the vacuum pump 1. The cooling mechanism 3 is used to cool the exhaust gas to avoid the problem of hot gas affecting the working environment.

[0025] The cooling mechanism 3 includes an outer pipe 31, which is detachably connected to the output end of the vacuum pump 1 via a flange structure. In this embodiment, flange interfaces are provided on both the end of the outer pipe 31 and the output end of the vacuum pump 1. The two flange interfaces can be fixed together by bolts. In a preferred embodiment, the joint surfaces of the two flange interfaces can be provided with a beveled structure. Thus, when the outer pipe 31 is connected, it can be arranged in an inclined structure. If condensate is generated during cooling, it can flow downward along the inclined angle of the outer pipe 31 to facilitate subsequent centralized cleaning.

[0026] A spiral water pipe 32 is placed inside the outer pipe 31. Both ends of the spiral water pipe 32 extend to the outside of the outer pipe 31 and are connected to the water cooling circulation assembly, the water circulation assembly water tank, and the water pump. The two ends of the spiral water pipe 32 are connected to the water tank and the water pump. Of course, an air-cooled or refrigeration plate cooling structure should also be installed on the water tank to ensure that cool water with a low temperature can continuously flow in the spiral water pipe 32.

[0027] In some embodiments, in this invention, a middle tube 34 is fixedly connected to the inner side of the outer tube 31 by an outer bracket 33, and an inner tube 36 is fixedly connected to the inner side of the middle tube 34 by an inner bracket 35. Specifically, the outer bracket 33 and the inner bracket 35 in this embodiment have the same structure and can be either sheet-like or columnar. Multiple such brackets can be provided to improve the stability of the support without obstructing the flow of gas. An outer channel is formed between the outer tube 31 and the middle tube 34, and an inner channel is formed between the middle tube 34 and the inner tube 36.

[0028] The outer channel and the inner channel are connected.

[0029] Based on the above embodiments, in this embodiment, the spiral water pipe 32 is wound around the outside of the inner pipe 36 and located inside the middle pipe 34, with both ends of the spiral water pipe 32 passing through the middle pipe 34 and the outer pipe 31 in sequence.

[0030] In other words, in this embodiment, by adopting the design of the middle pipe 34 and the inner pipe 36, which are located on both sides of the spiral water pipe 32, when the vacuum pump 1 discharges gas, the gas first flows along the inner pipe 36 for initial cooling, and then the cooled gas enters between the middle pipe 34 and the inner pipe 36 for secondary cooling. Finally, the gas is discharged along the middle pipe 34 and the outer pipe 31. This design increases the gas flow path and greatly improves the cooling effect of the gas.

[0031] It should be noted that this embodiment also includes a plug 37, which is threaded to the end of the outer tube 31. The end face of the plug 37 is provided with a plurality of vent holes 371, which are connected to the outer channel. Specifically, in this embodiment, the vent holes 371 on the plug 37 are connected between the outer tube 31 and the middle tube 34, so as to ensure that the cooled gas can be discharged smoothly.

[0032] Based on the above embodiments, in this embodiment, the inner end of the plug 37 abuts against and seals the end of the middle tube 34, and the end of the inner tube 36 is a predetermined distance away from the plug 37. That is to say, in this embodiment, the end of the middle tube 34 is sealed by the plug 37. At the same time, since there is a distance between the inner tube 36 and the plug 37, the gas in the inner tube 36 will change direction and move towards the space between the middle tube 34 and the inner tube 36 when it comes into contact with the plug 37. This can ensure that the gas undergoes multiple cooling operations. At the same time, when the plug 37 is disassembled, the condensate in the outer tube 31, the middle tube 34 and the inner tube 36 can be easily discharged.

[0033] Based on the above embodiments, in this embodiment, the outer end of the inner tube 36 is inserted into the output port of the vacuum pump 1. A sealing gasket 38 is also fixedly installed on the outside of the inner tube 36. The sealing gasket 38 seals the connection between the inner tube 36 and the output port of the vacuum pump 1. In this embodiment, the outer side of the inner tube 36 has an annular platform. The sealing gasket 38 is sleeved on the outside of the inner tube 36 and abuts against the annular platform for limitation. The design of the sealing gasket 38 is used to improve the connection sealing between the inner tube 36 and the output port flange of the vacuum pump 1, so as to ensure that all gas can enter the inner tube 36.

[0034] Preferably, in this embodiment, the input pipe 2 has a deformable section 21 in the middle. Specifically, the deformable section 21 is set as a corrugated pipe section. The design of the corrugated pipe section is to give the end of the input pipe 2 a certain amount of adjustable space. In this way, when connecting the coating equipment, the installation error can be adapted within a certain range to improve the convenience of installation.

[0035] In summary, by connecting a cooling mechanism 3 to the output end of the vacuum pump 1, the cooling mechanism 3 cools the exhaust gas during reciprocating operation because the inside of the coating device will generate high temperature after the reaction, thus ensuring the comfort of the working environment. In addition, the cooling mechanism 3 in this invention adopts a multi-channel and multiple cooling method, which can greatly improve the cooling effect of the gas.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
