Description

Technical Field

[0001] This utility model relates to the technical field of optical glass coating process, and in particular to an adsorption device and a coating equipment. Background Technology

[0002] In the TFT (Thin Film Transistor) industry, photoresist coating equipment requires a pre-adhesive adsorption process on large-size glass before photoresist coating to prevent glass bending. However, as LCD manufacturers increase the size of substrates in higher-generation lines, the degree of glass bending also increases, meaning the glass may exhibit poor flatness. This makes it difficult for existing adsorption devices to adhere to the glass edges, leading to frequent shutdowns of the coating equipment due to adsorption abnormalities and disruptions to normal production.

[0003] Therefore, how to achieve good adsorption of large-size glass is a technical problem that urgently needs to be solved. Utility Model Content

[0010] In one embodiment of this utility model, the adsorption structure further includes a second installation space, the suction cup is disposed in the second installation space, and the interior of the suction cup is connected to the second installation space; wherein, the first installation space is connected to the second installation space so that when the end of the support rod away from the adsorption structure is connected to the external negative air pressure, the second installation space is a vacuum environment.

[0011] In one embodiment of this utility model, the inner diameter of the adsorption structure at the end near the suction cup is less than or equal to 4 mm.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figure 1 and Figure 2As shown, this embodiment of the present invention provides an adsorption device 10. The adsorption device 10 provided in this embodiment of the present invention is, for example, used in photopolymer coating equipment in the TFT (Thin Film Transistor) industry. Users can install the adsorption device 10 on the photopolymer coating equipment, thereby enabling the adsorption device 10 to effectively adsorb glass, facilitating subsequent coating operations.

[0025] For details, please refer to [link / reference]. Figure 1 and Figure 2 The adsorption device 10 includes, for example, a support structure 100 and an adsorption structure 200. The support structure 100 includes a first end 101 and a second end 102 opposite to the device. The first end 101 is used to connect to an external negative air pressure. The adsorption structure 200 is disposed at the second end 102 of the support structure 100 and is connected to the support structure 100. The end of the adsorption structure 200 away from the support structure 100 is equipped with a suction cup 210, and the interior of the suction cup 210 is connected to the interior of the adsorption structure 200.

[0026] The adsorption device provided in this embodiment of the utility model is provided with a support structure and an adsorption structure. The support structure can be connected to an external negative pressure, and the adsorption structure is connected to the support structure. The adsorption structure is provided with a suction cup, which is connected to the adsorption structure. Thus, when the support structure is connected to the external negative pressure, the inside of the adsorption structure is a vacuum environment. Therefore, the suction cup can tightly adsorb the glass, thereby solving the problem that large-sized glass is easy to warp and difficult to adsorb.

[0027] Further, see Figure 1 and Figure 2 The support structure 100 includes a support base 110 and a support rod 120. The support rod 120 is disposed on the support base 110, and the adsorption structure 200 is disposed on the end of the support rod 120 away from the support base 100. As described above, the adsorption structure 200 is sleeved on the outer side of the end of the support rod 120 away from the support base 110.

[0028] For details, see Figure 3The support rod 120 includes an internal hollow structure 121, and the end of the support rod 120 away from the adsorption structure 200 is connected to the external negative pressure. The adsorption structure 200 includes a first mounting space 201, and the support rod 120 is disposed within the first mounting space 201, with the internal hollow structure 121 of the support rod 120 connected to the first mounting space 201. The adsorption structure 200 also includes a second mounting space 202, and the suction cup 210 is disposed within the second mounting space 202, with the interior of the suction cup 210 connected to the second mounting space 202; wherein, the first mounting space 201 and the second mounting space 202 are connected so that when the end of the support rod 120 away from the adsorption structure 200 is connected to the external negative pressure, the second mounting space 202 is a vacuum environment. In this way, the suction cup 210 can better adsorb glass through the pressure difference.

[0029] In one specific embodiment, the inner diameter of the adsorption structure 200 near the suction cup 210 is less than or equal to 4 mm. The inner diameter of the support rod is less than or equal to 2 mm. This allows for better adsorption of glass and ensures compatibility with most adhesive coating equipment currently on the market.

[0030] For example, the adsorption device 10 provided in this embodiment of the present invention is applied to a photopolymer coating equipment. The photopolymer coating equipment includes, for example, a main body and a shuttle, and the adsorption device 10 is installed on the main body. Specifically, when large-size glass needs to be coated, the existing photopolymer coating equipment performs the following process: the adsorption structure rises, the large glass (short side) is lifted → the shuttle moves below the glass → the adsorption structure descends → the adsorption structure draws a vacuum to open the glass and achieves a set negative pressure value → the shuttle moves to perform the coating action. The photopolymer coating equipment equipped with the adsorption device 10 provided in this embodiment performs the following process: the adsorption device 10 (with suction cup 210) rises and holds the glass, the glass (short side) is lifted and held → the shuttle moves below the glass → the adsorption device 10 descends (the suction cup 210 assists in pulling down the glass) → the adsorption device 10 draws a vacuum to open the glass and achieves a set negative pressure value → the suction cup 210 breaks the vacuum and releases the glass → the shuttle moves to perform the coating action.

[0031] In summary, the adsorption device provided by this utility model embodiment is provided with a support structure and an adsorption structure. The support structure can be connected to an external negative pressure, and the adsorption structure is connected to the support structure. The adsorption structure is provided with a suction cup, which is connected to the adsorption structure. Thus, when the support structure is connected to the external negative pressure, the inside of the adsorption structure is a vacuum environment. Therefore, the suction cup can tightly adsorb the glass, thereby solving the problem that large-sized glass is easy to warp and difficult to adsorb.

[0032] On the other hand, this utility model also provides an adhesive coating device. The adhesive coating device includes, for example, a main body and the aforementioned adsorption device 10. The support structure 100 is fixedly mounted on the main body at one end away from the suction cup 210, and the adsorption device 10 is at least one.

[0033] Preferably, the number of adsorption devices 10 is four, and the four adsorption devices 10 are arranged in a rectangular shape. This is to match the shape of the glass as closely as possible, thereby enabling better adsorption of the glass.

[0034] In summary, the adsorption device provided by this utility model embodiment is provided with a support structure and an adsorption structure. The support structure can be connected to an external negative pressure, and the adsorption structure is connected to the support structure. The adsorption structure is provided with a suction cup, which is connected to the adsorption structure. Thus, when the support structure is connected to the external negative pressure, the inside of the adsorption structure is a vacuum environment. Therefore, the suction cup can tightly adsorb the glass, thereby solving the problem that large-sized glass is easy to warp and difficult to adsorb.
