Description

Technical Field

[0001] The utility model belongs to the technical field of mask cleaning, and in particular relates to a device for cleaning an OLED vapor-deposited metal mask. Background Art

[0002] If evaporation is the heart of OLED, then metal mask is the root of evaporation. It is an indispensable high-value core production consumable in the OLED evaporation process. It needs to be replaced regularly and has a high production cost. Its main material is metal or metal and resin. Its main function is to deposit RGB organic substances and form pixels in the OLED production process, and to accurately and finely deposit organic substances where needed. Masks are very critical in the OLED panel production process and determine the yield and resolution of OLED screen production.

[0003] Because the mask has high precision requirements and is expensive, and the cleanliness of the mask has a great impact on the evaporation process, cleaning the mask has become an indispensable process.

[0004] Currently, the mask is cleaned by placing it directly in a cleaning tank, soaking it with solvent and cleaning it. During cleaning, the mask and the cleaning agent cannot fully contact each other, resulting in poor cleaning effect. The mask is not convenient to take and put, which can easily cause damage to the mask. Cleaning can easily lead to a waste of solvent. At the same time, there is more contact between personnel and the cleaning agent, which increases the risk.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0030] like Figure 1 to Figure 4 As shown, a device for cleaning an OLED vapor deposition metal mask in an embodiment of the utility model comprises a cleaning device 1, a placement frame 2 and a mask 3.

[0031] like Figure 1 to Figure 4 As shown, the cleaning device 1 includes a cleaning device body 11, which is used to store cleaning agent. The upper end of the cleaning device body 11 is set as an opening, which facilitates the addition of cleaning agent and the placement of the mask version body 31.

[0032] like Figure 1 to Figure 5 As shown, the placement frame 2 includes a placement frame body 21, which is placed in the cleaning device body 11, and is used to place the mask version body 31; a plurality of through holes 22 are provided on the wall panels of the placement frame body 21, and the cleaning agent in the cleaning device body 11 can contact the mask version body 31 through the plurality of through holes 22; a plurality of support rods 23 are fixedly connected to the inner walls of the left and right wall panels of the placement frame body 21, and the support rods 23 are used to support the mask version body 31, thereby ensuring the stability of the mask version body 31 during cleaning.

[0033] like Figure 4 and Figure 5 As shown, the mask plate 3 includes a mask plate body 31, and the mask plate body 31 is installed in the placement frame body 21, so that the mask plate body 31 is placed in the cleaning device body 11 through the placement frame body 21 for cleaning.

[0034] Preferably, since the mask version body 31 is placed in the placement frame body 21 during cleaning, the mask version body 31 is taken and moved by the placement frame body 21, and the placement frame body 21 can protect the mask version body 31, thereby avoiding damage to the mask version body 31 due to touching during taking.

[0035] like Figure 1 to Figure 3 As shown, the cleaning device body 11 is composed of a bottom wall panel and surrounding wall panels. The connection between the bottom wall panel and the surrounding wall panels of the cleaning device body 11 is formed in an integrated manner. The integrated connection method ensures that there is no gap at the connection, ensuring that the cleaning liquid in the cleaning device body 11 will not leak through the gap.

[0036] like Figure 1 to Figure 4 As shown, a pair of first handles 12 are hingedly connected to the upper portions of the outer side walls of the left and right wall panels of the cleaning device body 11 , and the first handles 12 facilitate movement of the cleaning device body 11 .

[0037] like Figure 5 As shown, the placement frame body 21 is composed of multiple outer wall panels. The placement frame body 21 is set as a hollow structure to facilitate the placement of the mask version body 31. The front end of the placement frame body 21 is provided with an opening, so that the mask version body 31 is easy to take out of the placement frame body 21.

[0038] Preferably, the plurality of outer side wall panels of the placement frame body 21 are connected by integral molding, and the integral molding connection method makes the placement frame body 21 structurally stable.

[0039] like Figure 4 As shown, the upper surfaces of the multiple support rods 23 on the left side wall panel of the placement frame body 21 and the multiple support rods 23 on the right side wall panel of the placement frame body 21 are all on the same horizontal line, so that when the support rods 23 support the mask version body 31, the mask version body 31 is in a horizontal state, thereby facilitating the cleaning of the mask version body 31.

[0040] like Figure 4As shown, the support rod 23 is set to a hollow structure, so as to ensure the strength of the support rod 23 while reducing its own weight, so that the weight of the placement frame 2 is light, so that it is convenient for the placement frame 2 to drive the mask version body 31 to move. A certain distance is set between the multiple support rods 23 and between the upper support rod 23 and the upper end wall plate of the placement frame body 21, so as to facilitate the placement of the mask version body 31.

[0041] like Figure 1 to Figure 5 As shown, a pair of connecting parts 24 are fixedly connected to the upper side wall plate of the placing frame body 21, and a second handle 25 is hinged on the pair of connecting parts 24. The second handle 25 makes it easy to take the placing frame body 21 when it is placed in the cleaning device body 11, so as to facilitate the taking of the mask version body 31 when cleaning.

[0044] Preferably, in the present application, all components except the mask body 31 are made of stainless steel. Since the cleaning agent has a certain corrosiveness, the device is made of stainless steel to avoid corrosion to the device by the cleaning agent, thereby increasing the service life of the device.

[0045] When in use, the cleaning agent is poured into the cleaning device body 11, and the mask version body 31 to be cleaned is placed in the placement frame body 21, and the mask version body 31 is supported by the support rod 23. Then, the placement frame body 21 can be placed in the cleaning device body 11 by carrying the second handle 25, and the cleaning agent in the cleaning device body 11 can fully contact the upper and lower surfaces of the mask version body 31 through the through hole 22, thereby improving the cleaning effect of the mask version body 31. After cleaning, the placement frame body 21 can be taken out of the cleaning device body 11 by carrying the second handle 25, so that the mask version body 31 can be taken out. When taking it out, the placement frame body 21 can protect the mask version body 31 to avoid damage to the mask version body 31 during taking it out. At the same time, when taking it out before and after cleaning, the operator's hand can be touched with the second handle 25 to avoid contact with the cleaning agent.
