Description

Technical Field

[0001] The utility model relates to the field of coating equipment technology, in particular to a coating equipment for long grating glass. Background Art

[0002] With the advancement of science and technology, various new types of glass are emerging, and coated glass is one of them. Coated glass is a glass surface coated with one or more layers of metal, alloy or metal compound film to change the optical properties of the glass to meet certain specific requirements.

[0003] At present, for the coating of large pieces of glass (such as architectural glass, LCD mask glass, etc.), most of them are mainly laid flat and continuously coated. The coating process mainly uses continuous coating equipment. The main structure of this continuous coating equipment includes a feeding area, a first rough vacuum area, a first high vacuum area, a coating area, a second high vacuum area, a second rough vacuum area and a discharging area. The feeding area, the first rough vacuum area, the first high vacuum area, the coating area, the second high vacuum area, the second rough vacuum area and the discharging area are arranged horizontally in sequence. During the coating process, large pieces of glass are laid flat on the rack and enter each area in sequence to complete the coating.

[0004] However, for the coating of long grating glass, due to the needs of the subsequent process, the glass needs to be cut into thin strips before coating, and its aspect ratio is more than 100:1. If the above-mentioned continuous coating equipment is used for flat coating, it is easy to cause dust during coating and cause pinholes. At the same time, since the production volume of long grating glass is not large, the above-mentioned continuous coating equipment has a high equipment cost and occupies a large space, which is not suitable for coating long grating glass. Therefore, it is necessary to study a coating equipment suitable for coating long grating glass. Utility Model Content

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a coating device for long grating glass, which can effectively solve the problem that the existing continuous coating device is not suitable for coating long grating glass.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A coating device for long grating glass comprises an inlet and outlet chamber, a coating chamber and a buffer chamber which are connected in parallel in sequence; a first valve is arranged at the inlet and outlet end of the inlet and outlet chamber, a heating device, an ion cleaning device and a first conveying device are arranged in the inlet and outlet chamber, and a first vacuum pumping device for vacuuming the inlet and outlet chamber is arranged outside the inlet and outlet chamber; a second valve is arranged at the connection between the coating chamber and the inlet and outlet chamber, a vacuum breaking valve is arranged on the inlet and outlet chamber, a coating device is arranged in the coating chamber, a second conveying device is arranged in the coating chamber and the buffer chamber, and a second vacuum pumping device for vacuuming the coating chamber and the buffer chamber is arranged outside the buffer chamber.

[0008] As a preferred solution, the inlet and outlet ends of the inlet and outlet chamber are provided with upper and lower material racks, which include a base, a conveying roller, a conveying group and a glass hanger. The conveying roller and the conveying group are both arranged on the base, and the conveying group drives the conveying roller to operate. The glass hanger is arranged on the base and is conveyed by the conveying roller.

[0009] As a preferred solution, the first conveying device is a roller conveying device.

[0010] As a preferred solution, the first valve is a pneumatic valve.

[0011] As a preferred solution, the second conveying device is a roller conveying device.

[0012] As a preferred solution, the second valve is a pneumatic valve.

[0013] As a preferred solution, a maintenance hole is provided on the side of the buffer chamber.

[0014] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0015] By setting up the feeding and discharging chamber, the coating chamber and the buffer chamber, and coordinating with various valves and devices, the long grating glass placed horizontally on the glass rack can be coated. During the coating, dust will not fall and cause pinholes, and the coating quality is better.

The glass hanger 64 is arranged on the base 61 and is conveyed by the conveying roller 62, so as to feed and discharge the long grating glass. In addition, a magnetic restraint magnet 65 is arranged on the upper side of the loading and unloading rack 60, and a magnetic restraint fixing device 66 cooperating with the magnetic restraint magnet 65 is arranged in the loading and unloading chamber 10, the coating chamber 20 and the buffer chamber 30 to form a magnetic restraint structure, thereby stabilizing the loading and unloading rack 60 so that it does not swing back during the movement and has no direct contact with the loading and unloading chamber 10, the coating chamber 20 and the buffer chamber 30, thereby reducing dust caused by friction.

[0036] A second valve 42 is provided at the connection between the coating chamber 20 and the inlet and outlet chamber 10, a vacuum breaking valve 43 is provided on the inlet and outlet chamber 10, a middle coating device 71 is provided in the coating chamber 20, a second conveying device 72 is provided in the coating chamber 20 and the buffer chamber 30, and a second vacuum pumping device 73 for vacuuming the coating chamber 20 and the buffer chamber 30 is provided outside the buffer chamber 30.

[0037] The working principle of this embodiment is described in detail as follows:

[0038] First, the long grating glass is placed horizontally on the glass rack 64. Multiple layers of long grating glass can be placed on the glass rack 64. Then, the first valve 41 is opened, and the second valve 42 remains closed. The rack 64 is sent into the inlet and outlet chamber 10, and the long grating glass enters the inlet and outlet chamber 10 with the rack 64. Then, the first valve 41 is closed. Then, the interior of the inlet and outlet chamber 10 is heated by the heating device 51, and the long grating glass is ion-cleaned by the ion cleaning device 52. During the heating and cleaning process, the inlet and outlet chamber 10 is evacuated by the first vacuuming device 54, so that the interior of the inlet and outlet chamber 10 reaches a vacuum state. Then, the second valve 42 is opened, and the first valve 41 is kept closed. The glass rack 64 is transported to the coating chamber 20 by the first conveying device 53, and the long grating glass enters the coating chamber 20 with the glass rack 64. Then, in the coating chamber 20, the second conveying device 72 drives the glass rack 64 to move, and at the same time, the coating device 71 coats the long grating glass on the glass rack 64. When the glass rack 64 completely leaves the coating chamber 20 and enters the buffer chamber 30, the coating operation is completed. Then, the second conveying device 72 drives the glass rack 64 to move in the opposite direction and enter the inlet and outlet chamber 10. Then, the second valve 42 is closed to ensure that the coating chamber 20 is maintained in a high vacuum state. Then, the vacuum breaking valve 43 is opened, and then the first valve 41 is opened. The first conveying device 53 conveys the glass rack 64 in the opposite direction to the upper and lower material racks 60. At this time, the coated long grating glass can be removed from the glass rack 64, and another batch of coated long grating glass can be placed on the glass rack 64, and then the coating operation can be performed as described above.

[0039] The design focus of the utility model is: by setting the feeding and discharging chamber, the coating chamber and the buffer chamber, and coordinating the valves and the devices, the long grating glass placed horizontally on the glass rack can be coated.
