Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an observation window. Background Technology

[0002] In the field of coating, a viewing window with a good field of view is crucial. The production control process can be accomplished through the viewing window. For example, the selection of production nodes and the judgment of certain equipment states are all determined by observing the situation inside the chamber through the viewing window.

[0003] The observation windows of existing coating equipment almost all use a layer of anti-fouling glass and an open baffle for protection. During the coating process, the open baffle is always open, and the film material will splash onto the anti-fouling glass through the holes of the outermost baffle, causing the anti-fouling glass to become scratched quickly and affecting the view. Furthermore, the structure of the observation window in the existing technology requires the main sealing glass of the observation window to be removed when replacing the anti-fouling glass. Repeated disassembly and reassembly will damage the vacuum sealing structure of the observation equipment, leading to damage to the main sealing glass.

[0004] Therefore, there is an urgent need for an observation window to solve the problems in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide an observation window that allows for the replacement of the anti-fouling glass without damaging its sealing structure, thus ensuring the airtightness of the observation window and improving the efficiency of replacing the anti-fouling glass.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The viewing window includes:

[0008] The base has a first through hole;

[0009] The first shielding plate is detachably mounted on the base and blocks the first through hole. The first shielding plate is provided with at least one first observation hole.

[0010] A rotating assembly, comprising a rotating ring, a second baffle plate, and a dirt-proof glass, wherein the rotating ring is rotatably mounted on the base, the second baffle plate is detachably mounted on the first end of the rotating ring, the second baffle plate is provided with a second observation hole, and the dirt-proof glass is detachably mounted on the second end of the rotating ring;

[0011] A cover plate assembly, the cover plate assembly including a sealing glass, the sealing glass being fitted onto the end face of the second end of the rotating ring.

[0012] Optionally, the rotating assembly further includes a ball bearing. The base is provided with an annular groove, and a plurality of balls are disposed in the annular groove. The balls are in rolling connection with the rotating ring.

[0013] Optionally, the observation window further includes a fixing ring, which is fixedly disposed on the base, and the end of the fixing ring facing away from the base is provided with a first limiting edge along the circumference of the fixing ring. The first limiting edge is used to restrict the axial movement of the rotating ring along the first through hole.

[0014] Optionally, the rotating assembly further includes a retaining ring and a first buffer washer, the first buffer washer being disposed between the anti-fouling glass and the sealing glass, the retaining ring being disposed on the side of the anti-fouling glass away from the sealing glass, and the retaining ring being engaged with the inner wall of the rotating ring.

[0015] Optionally, both the first observation hole and the second observation hole are fan-shaped holes.

[0016] Optionally, the rotating assembly further includes a first sealing ring, a first sealing groove is provided on the wall of the first through hole, the first sealing ring is located in the first sealing groove, and the first sealing ring is used to seal the connection between the rotating ring and the wall of the first through hole.

[0017] Optionally, the second end of the rotating ring is provided with a second sealing groove, and a second sealing ring is provided in the second sealing groove. The second sealing ring is used to seal the connection between the sealing glass and the rotating ring.

[0018] Optionally, the cover plate assembly further includes a cover plate disposed on the rotating ring, the cover plate having a second through hole, the sealing glass being sandwiched between the cover plate and the rotating ring, and the sealing glass blocking the second through hole.

[0021] Beneficial effects:

[0022] The observation window provided by this utility model features a second baffle plate at the first end of a rotating ring. When observation of the interior of the chamber is not required, rotating the ring causes the second observation hole on the second baffle plate to be misaligned with the first observation hole on the first baffle plate. This effectively prevents film from splashing onto the anti-fouling glass during the coating process, thereby reducing contamination and the frequency of replacement. When observation of the interior of the chamber is required, rotating the ring aligns the second observation hole on the second baffle plate with the first observation hole on the first baffle plate, providing a clear view and ensuring accurate observation of the interior. Furthermore, the first baffle plate is detachably mounted on the base, and the second baffle plate is detachably mounted at the first end of the rotating ring. This allows for replacement of the anti-fouling glass without damaging its sealing structure, ensuring the sealing performance of the observation window and improving the efficiency of replacing the anti-fouling glass.

[0038] This embodiment provides an observation window, such as Figures 1-4As shown, the observation window includes a base 100, a first baffle 200, a rotating assembly 300, and a cover assembly 400. The base 100 has a first through hole 110. The first baffle 200 is detachably mounted on the base 100 and blocks the first through hole 110. The first baffle 200 has at least one first observation hole 210. The rotating assembly 300 includes a rotating ring 310, a second baffle 320, and a dirt-proof glass 330. The rotating ring 310 is rotatably mounted on the base 100. The second baffle 320 is detachably mounted on the first end of the rotating ring 310 and has a second observation hole 321. The dirt-proof glass 330 is detachably mounted on the second end of the rotating ring 310. The cover assembly 400 includes a sealing glass 410, which is attached to the end face of the second end of the rotating ring 310. By rotating the second obstruction plate 320 at the first end of the rotating ring 310, when it is not necessary to observe the internal condition of the cavity, the second observation hole 321 on the second obstruction plate 320 is offset from the first observation hole 210 on the first obstruction plate 200. This effectively prevents the film material from splashing onto the anti-fouling glass 330 during the coating process, thereby reducing the contamination of the anti-fouling glass 330 and reducing the replacement frequency of the anti-fouling glass 330. When it is necessary to observe the internal condition of the cavity, by rotating the rotating ring 310, the second observation hole 321 on the second obstruction plate 320 is aligned with the first observation hole 210 on the first obstruction plate 200, a clear field of vision can be obtained, ensuring that the operator can accurately observe the internal condition of the cavity.

[0039] The observation window provided in this embodiment has a first baffle plate 200 detachably mounted on the base 100 and a second baffle plate 320 detachably mounted on the first end of the rotating ring 310. This allows for the replacement of the anti-fouling glass 330 without damaging the sealing structure of the sealing glass 410, and also improves the efficiency of replacing the anti-fouling glass 330.

[0040] Optionally, such as Figures 1-2 As shown, the rotating assembly 300 also includes a ball bearing 121. A base 100 has an annular groove 120, and several balls 121 are disposed within the annular groove 120, rollingly connected to the rotating ring 310. The balls 121 can roll freely within the annular groove 120, reducing friction during the rotation of the rotating ring 310 and thus providing smoother rotational movement. This ensures that the operator can easily and seamlessly adjust the position of the observation window to obtain the required field of view, improving the smoothness and accuracy of operation.

[0041] Optionally, the observation window also includes a retaining ring 130, which is fastened to the base 100 by screws. The end of the retaining ring 130 facing away from the base 100 is provided with a first limiting edge 131 along the circumference of the retaining ring 130. The first limiting edge 131 is used to limit the axial movement of the rotating ring 310 along the first through hole 110, ensuring that the rotating ring 310 is in the proper position and does not move unnecessarily along the first through hole 110 of the base 100. This increases the stability and accuracy of the observation window, making it easier to control and operate.

[0042] Optionally, the rotating assembly 300 further includes a retaining ring 340 and a first buffer washer 500. The first buffer washer 500 is disposed between the anti-fouling glass 330 and the sealing glass 410. The retaining ring 340 is disposed on the side of the anti-fouling glass 330 opposite to the sealing glass 410, and the retaining ring 340 is engaged with the inner wall of the rotating ring 310. It can be understood that the left side of the anti-fouling glass 330 is limited by the sealing glass 410, and the right side of the anti-fouling glass 330 is limited by the retaining ring 340, thereby fixing the anti-fouling glass 330 to the second end of the rotating ring 310.

[0043] Specifically, in this embodiment, the retaining ring 340 is Ω-shaped so that the retaining ring 340 has sufficient elasticity to be engaged on the inner wall of the first through hole 110.

[0044] Optionally, the first baffle plate 200 is locked to the base 100 by a first fastening screw, ensuring a more stable connection between the first baffle plate 200 and the base 100, and facilitating the installation and removal of the first baffle plate 200. The second baffle plate 320 is locked to the first end of the rotating ring 310 by a second fastening screw, ensuring a more stable connection between the second baffle plate 320 and the rotating ring 310, and facilitating the installation and removal of the second baffle plate 320. Understandably, when the anti-fouling glass 330 needs to be replaced, the first baffle plate 200 is removed from the base 100, the second baffle plate 320 is removed from the rotating ring 310, and then the retaining ring 340 is removed from the rotating ring 310 to replace the anti-fouling glass 330. After replacing the anti-fouling glass 330, the retaining ring 340, the second baffle plate 320, and the first baffle plate 200 are reinstalled in sequence. The replacement of the anti-fouling glass 330 does not require damaging the sealing structure of the observation window, thus improving replacement efficiency.

[0045] Optionally, such as Figures 3-4As shown, both the first observation hole 210 and the second observation hole 321 are fan-shaped holes. The fan-shaped hole design provides a wide field of view, allowing the operator to observe more areas. In other embodiments, the shapes of the first observation hole 210 and the second observation hole 321 can be circular, triangular, rhomboid, or trapezoidal, etc. There are no specific limitations on the shape and number of the first observation hole 210 and the second observation hole 321, as long as the number, size, and shape of the first observation hole 210 and the second observation hole 321 are consistent.

[0046] Furthermore, in this embodiment, two symmetrical first observation holes 210 are provided on the first shielding plate 200, and two symmetrical second observation holes 321 are provided on the second shielding plate 320. By rotating the rotating ring 310, the second observation holes 321 on the second shielding plate 320 are aligned with the corresponding first observation holes 210 on the first shielding plate 200 to obtain an observation field of view.

[0047] Optionally, the rotating assembly 300 further includes a first sealing ring 141. A first sealing groove 140 is provided on the wall of the first through hole 110. The first sealing ring 141 is located in the first sealing groove 140. The first sealing ring 141 is used to seal the connection between the rotating ring 310 and the wall of the first through hole 110, ensuring the sealing between the outer wall of the rotating ring 310 and the inner wall of the first through hole 110 during the rotation of the rotating ring 310, and preventing the film material from splashing onto the sealing glass 410 through the connection gap between the rotating ring 310 and the base 100.

[0048] Specifically, in this embodiment, two first sealing grooves 140 are provided on the wall of the first through hole 110, and a first sealing ring 141 is provided in each first sealing groove 140. The arrangement of two first sealing grooves 140 and two first sealing rings 141 can provide double sealing protection, increasing the sealing performance at the connection between the rotating ring 310 and the wall of the first through hole 110.

[0049] Optionally, the second end of the rotating ring 310 is provided with a second sealing groove 311, and a second sealing ring 3111 is provided in the second sealing groove 311. The second sealing ring 3111 is used to seal the connection between the sealing glass 410 and the rotating ring 310, which improves the sealing performance of the observation window and ensures that a good seal is maintained at the connection between the sealing glass 410 and the rotating ring 310, preventing gas or contaminants from entering the inner cavity or leaking out.

[0050] Optionally, the cover plate assembly 400 further includes a cover plate 420, which is disposed on the rotating ring 310. The cover plate 420 has a second through hole 421. A sealing glass 410 is sandwiched between the cover plate 420 and the rotating ring 310, and the sealing glass 410 blocks the second through hole 421. By providing the second through hole 421 in the cover plate 420, the operator can obtain a field of view.

[0051] Furthermore, a second limiting edge 422 is provided on the cover plate 420 along the circumference of the second through hole 421. The second limiting edge 422 is used to make the sealing glass 410 fit against the end face of the second end of the rotating ring 310, thereby preventing the sealing glass 410 from loosening and shifting, and improving the stability of the sealing glass 410.

[0052] Optionally, a buffer mounting groove 4221 is provided on the second limiting edge 422, and a second buffer washer 600 is provided in the buffer mounting groove 4221. The second buffer washer 600 is used to buffer the connection between the sealing glass 410 and the second limiting edge 422, which helps to reduce the impact of vibration, impact or other mechanical stress on the sealing glass 410 and improve the service life of the sealing glass 410.

[0053] Optionally, a third sealing groove 150 is provided on the side of the base 100 away from the cover plate 420, and a third sealing ring 151 is provided in the third sealing groove 150. The third sealing ring 151 is used to ensure the sealing of the connection between the base 100 and the side wall of the chamber when the observation window is installed on the side wall of the coating chamber, so as to ensure the sealing effect in the coating chamber.
