Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and more specifically, the utility model relates to a vacuum observation window device. Background Art

[0002] In the precise operation of continuous line coating and vacuum equipment, sensors play a crucial role. They assist in precisely adjusting the rhythm of substrate movement by emitting and receiving light source signals, ensuring the continuity and stability of the production process. Since a high vacuum state needs to be maintained inside these devices, sensors must be designed to meet the requirements of vacuum sealing and be equipped with light transmission devices to ensure unobstructed transmission of light signals, thereby enabling precise monitoring and control of the production process. The current vacuum window technology, although achieving a tight vacuum seal between the metal joint and the lens, significantly increases the manufacturing cost and relies on special vacuum brazing equipment. More disadvantageously, once the lens is contaminated by the environment, the cleaning and replacement process becomes complex and inefficient, directly restricting the smoothness of the production process, affecting the overall beat efficiency, and posing significant challenges to production management and cost control.

[0016] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0017] Such as Figures 1 to 5As shown in the figure, the utility model provides a vacuum observation window device, which includes a KF flange connection seat 1. A fixing groove 6 is formed inside the KF flange connection seat 1. A sealing ring 5 is movably installed inside the fixing groove 6. A window lens 2 is fixedly placed inside the KF flange connection seat 1. A positioning anti-collision and pressure-resistant sheet 3 is fixedly and movably installed on the outer surface of the window lens 2. A threaded fastening pressure ring 4 is threadedly sleeved on the top of the positioning anti-collision and pressure-resistant sheet 3.

[0018] When the staff needs to assemble the window lens 2, first put the sealing ring 5 into the fixing groove 6, then place the window lens 2 inside the KF flange connection seat 1. Now place the positioning anti-collision and pressure-resistant sheet 3 on the outer surface of the window lens 2. At this time, hold the threaded fastening pressure ring 4 by hand and screw the threaded fastening pressure ring 4 into the KF flange connection seat 1 until it rotates above the positioning anti-collision and pressure-resistant sheet 3, thus completing the assembly of the window lens 2.

[0019] When it is necessary to assemble the window lens 2, first put the sealing ring 5 into the fixing groove 6, then place the window lens 2 inside the KF flange connection seat 1. Now place the positioning anti-collision and pressure-resistant sheet 3 on the outer surface of the window lens 2. At this time, hold the threaded fastening pressure ring 4 by hand and screw the threaded fastening pressure ring 4 into the KF flange connection seat 1 until it rotates above the positioning anti-collision and pressure-resistant sheet 3. Compared with traditional devices, this device is convenient for assembling the window lens 2 through the cooperation between the positioning anti-collision and pressure-resistant sheet 3 and the threaded fastening pressure ring 4. It has a compact structure and simple installation operation. With a general standard KF joint design, the installation process is fast and convenient. Its unique feature is that it can quickly and easily replace the contaminated lens, which can be easily disassembled through the threaded fastening pressure ring 4, improving the maintenance efficiency. To prevent the lens from accidentally breaking, the device is specially designed with a polytetrafluoroethylene gasket and a positioning sunk platform, effectively avoiding damage to the lens during the fastening process and ensuring the safety of long-term use. It has a low cost and can be made without special equipment, being economical and practical. Moreover, its multi-purpose feature allows users to replace lenses of different materials according to actual process requirements, flexibly adapting to various application scenarios, and is an ideal and indispensable choice in laboratories and industrial production.

[0020] Among them, a gasket is fixedly installed between the window lens 2 and the positioning anti-collision and pressure-resistant sheet 3, and a positioning sunk platform is arranged inside the gasket. The gasket is made of polytetrafluoroethylene material.

[0021] Since a gasket is fixedly installed between the window lens 2 and the positioning anti-collision and pressure-resistant sheet 3, and a positioning sunk platform is arranged inside the gasket, and the gasket is made of polytetrafluoroethylene material, it ensures that the window lens 2 maintains a safe distance from the internal thread of the threaded base when bearing the downward extrusion force and the tightening force, effectively avoiding direct contact and friction.

[0023] Since the inner part of the groove 7 is designed with a smooth surface inside the threaded fastening compression ring 4, it is convenient for the staff to place the rotary tool inside the threaded fastening compression ring 4. By rotating the rotary tool inside the threaded fastening compression ring 4, the threaded fastening compression ring 4 can be quickly screwed into the top of the positioning anti-collision pressing piece 3 and fixed by the positioning anti-collision pressing piece 3, ensuring the stability of the window lens 2 during use.

[0024] Among them, the inner diameter value of the KF flange connection seat 1 is smaller than the outer diameter value of the window lens 2, and the inner part of the KF flange connection seat 1 is designed with a smooth surface.

[0025] Since the inner diameter value of the KF flange connection seat 1 is smaller than the outer diameter value of the window lens 2 and the inner part of the KF flange connection seat 1 is designed with a smooth surface, it is convenient to quickly place the window lens 2 inside.

[0026] The working principle and usage process of the present utility model:
