Description

Technical Field

[0001] The present invention belongs to the technical field of glass substrate frames, and in particular, relates to a vacuum-coated glass substrate frame. Background Art

[0002] Glass vacuum coating is a technology that deposits a thin film of metal or alloy material onto the surface of glass. This coating process can improve the optical, mechanical and chemical properties of glass, making it more wear-resistant, corrosion-resistant and light-transmitting. Glass vacuum coating is often used to manufacture products such as optical devices, solar panels, and display screens.

[0003] In the prior art, when coating glass, the glass needs to be placed on a glass substrate rack, such as a glass substrate rack for vacuum coating and a coating system and a transmission method of the coating system with application number "CN201410197259.X". The transmission method of the glass substrate rack is that the glass substrate rack stands obliquely on the glass substrate rack transmission device and the edge of the frame accommodating area forms an inclined angle with the horizontal line of the bottom edge of the glass substrate rack in the horizontal direction. The transmission method of the glass substrate rack is used to replace the clamp by setting the concave frame accommodating area structure of the glass substrate rack and the respective positional relationship between the glass substrate rack and the concave frame accommodating area, so as to solve the problem of the clamp affecting the glass substrate. The problem of low coating yield rate such as coating shadow and small particle pollution on the glass substrate is caused; however, there are defects that the glass is difficult to remove and the corners are easily broken. For this reason, the patent of a vacuum-coated glass substrate rack and its coating system and a transmission method of the coating system with application number CN202011144981.9 makes improvements on this. The glass to be coated is clamped by upper and lower glass fixing springs, which will not scratch the glass surface and reduces the risk of damage to the glass corners. By utilizing the characteristics of the vacuum environment and through the internal and external air pressure difference under vacuum and atmospheric pressure conditions, the glass can be rotated 180° without the need for a motor drive, so that the glass can be coated on both sides, thereby improving the loading and unloading and coating efficiency of the glass.

[0004] However, the above-mentioned prior art still has obvious defects. The comparative document CN202011144981.9 mainly utilizes the expansion of the telescopic airbag to drive the extrusion plate to move through the internal and external air pressure difference under vacuum and atmospheric pressure conditions. However, the weight of the glass itself is relatively large, which will bring greater resistance to the expansion of the airbag, and the weight of glass of different materials and specifications is different. It is difficult to ensure that the telescopic airbag can be fully inflated every time, resulting in the glass flipping angle of less than 180 degrees, resulting in coating failure. Therefore, how to realize automatic double-sided coating of glass and how to control the transmission speed of glass in the vacuum coating chamber are problems that the present invention needs to solve. Summary of the invention

[0005] The object of the present invention is to provide a vacuum coated glass substrate rack, which solves the problems in the prior art of how to automatically coat the glass on both sides and how to control the transmission speed of the glass in the vacuum coating chamber.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A vacuum coated glass substrate rack comprises a substrate mounted on a transmission rack, wherein the transmission rack is composed of a first steel frame, a second steel frame and a plurality of cross beams, wherein the first steel frame and the second steel frame are arranged in parallel, and the cross beams are connected between the first steel frame and the second steel frame, and the substrate slides on the transmission rack through a sliding assembly; the transmission rack is used to transmit the glass substrate rack, and the transmission rack is arranged inside a vacuum coating chamber.

[0008] The first epitaxial plate and the second epitaxial plate are connected to both sides of the substrate respectively, the first epitaxial plate and the second epitaxial plate slide on the first steel frame and the second steel frame respectively, a rack plate is installed on the outer side of the first epitaxial plate, and a driving mechanism 1 for driving the rack plate to move is arranged on the outer side of the first steel frame;

When installing the glass, one end of the glass can pass through the hollow sleeve plate and then be inserted into the strip mounting groove. The hollow sleeve plate can be rotated 180 degrees around the rotating sleeve rod, and a driving mechanism 2 for driving the hollow sleeve plate to rotate is provided on the second extension plate.

[0010] Preferably, the driving mechanism 1 includes a driving motor 1 installed on one side of the first steel frame, and the output end of the driving motor 1 is connected to a gear matched with the rack plate, and one side of the gear is meshed with the rack plate. The driving motor 1 drives the gear to rotate, and the meshing relationship between the gear and the rack plate can drive the rack plate to transmit, thereby driving the substrate to transmit on the transmission frame.

The speed of the driving motor 1 can be set in advance according to the material of the glass, so that the transmission speed of the rack plate can be adjusted, thereby controlling the moving speed of the substrate carrying the processed glass in the vacuum coating chamber. For example, for some particularly high-cost glasses, more sufficient coating may be required, that is, the driving motor 1 is controlled to slow down, so that the transmission speed of the glass in the vacuum coating chamber is slow, so that the glass can be more fully coated.

[0012] Preferably, the second driving mechanism includes a semicircular support plate fixed on the second extension plate, and a connecting rod connected to one end of the hollow sleeve plate, the semicircular support plate is provided with an arc trajectory groove for the rotation of the connecting rod, one end of the connecting rod passes through the arc trajectory groove and is connected to a support block, the connecting rod can move inside the arc trajectory groove, and a second driving motor is installed on the second extension plate through the support block, the output end of the second driving motor is connected to a rotating plate, the rotating plate is provided with a movable groove, and the support block is arranged in the movable groove.

During the transmission process of the substrate carrying the glass, after the coating of the front half of the glass is completed, the hydraulic rod is started, and the hydraulic rod drives the support block to move through the connecting rod, thereby driving the connecting rod to move in the horizontal slide groove, thereby driving the hollow plate to move on the glass, so that the hollow plate moves to the position where the coating has been applied, so as to avoid the hollow plate blocking the glass, resulting in the blocked part of the glass not being coated.

[0014] Preferably, the sliding assembly includes a first slide groove provided inside the first steel frame and the second steel frame, and a plurality of pulleys are provided on both sides of the substrate, and the pulleys are in rolling contact with the inner wall of the first slide groove.

The top and bottom of the hollow sleeve are fixedly connected with sliding blocks, which can ensure that the hollow sleeve can still slide on the base plate after being turned over.

[0016] Beneficial effects of the present invention:

[0017] The present invention can drive the hollow sleeve plate to rotate 180 degrees through the second driving mechanism, and turn the glass to the other side for coating;

[0018] And through the design of the driving motor 1, gears and rack plate, the substrate can be driven to transmit on the transmission frame. After the coating on one side of the glass is completed, the glass is flipped and the driving motor 1 is rotated in the reverse direction, so that the substrate can be transmitted in the reverse direction to achieve coating on the other side of the glass.

[0034] Working principle of the present invention:

[0035] First, install the glass to be coated between the rotating sleeve rod 8 and the hollow sleeve plate 10, that is, one end of the glass passes through the hollow sleeve plate 10 and is installed in the strip installation groove 9 at one end of the rotating sleeve rod 8. The inner wall of the strip installation groove 9 is made of rubber material, which will not cause damage to the glass.

[0036] Then start the driving motor 11, the driving motor 11 drives the gear 12 to rotate, and the meshing relationship between the gear 12 and the rack plate 7 can drive the rack plate 7 to transmit, thereby driving the substrate 1 to transmit on the transmission rack, so that the substrate 1 carries the glass through the vacuum coating chamber for coating. The speed of the driving motor 11 can be set in advance according to the material of the glass, so that the transmission speed of the rack plate 7 can be adjusted, thereby controlling the moving speed of the substrate 1 carrying the processed glass in the vacuum coating chamber. For example, for some particularly high-cost glasses, more sufficient coating may be required, that is, the driving motor 11 can be controlled to slow down, so that the transmission speed of the glass in the vacuum coating chamber is slow, so that the glass can be coated more fully;

[0037] In addition, during the process of the substrate 1 carrying the glass for transmission, after the coating of the front half of the glass is completed, the hydraulic rod 23 is started, and the hydraulic rod 23 drives the support block 18 to move through the connecting rod 24, thereby driving the connecting rod 16 to move in the horizontal slide groove 22, thereby driving the hollow cover plate 10 to move on the glass, so that the hollow cover plate 10 moves to the coated position, so as to avoid the hollow cover plate 10 blocking the glass, resulting in the blocked part of the glass not being coated, until the processed glass side is completely coated, and then the hydraulic rod 23 is started again, and the hydraulic rod 23 drives the hollow cover plate 10 to reset, so that the connecting rod 16 is located at the connection between the arc track groove 17 and the horizontal slide groove 22;

[0038] After one side of the glass is completely coated, start the driving motor 19 again. The driving motor 19 drives the rotating plate 20 to rotate 180 degrees. During the rotation of the rotating plate 20, the connecting rod 16 is driven to slide along the arc track groove 17, so that the connecting rod 16 drives the hollow sleeve plate 10 to rotate, and the hollow sleeve plate 10 drives the glass to rotate 180 degrees to achieve the flipping of the glass. Then start the driving motor 11 to rotate counterclockwise, thereby driving the rack plate 7 to rotate in the opposite direction, thereby driving the rack plate 7 to rotate in the opposite direction, thereby driving the substrate 1 to move in the opposite direction, and driving the glass to pass through the vacuum coating chamber in the opposite direction to complete the double-sided coating of the glass.
