In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] The following is based on the attached Figure 2 To Attachment Fig.10 The utility model introduces a mask cleaning hanger.

[0042] Specifically, Figure 2 , Figure 3 As shown, the mask cleaning rack mainly includes a frame assembly 1 and a protruding fixing structure 2. The frame assembly 1 includes at least two frame structures, which are detachably connected and enclose a receiving space 100 capable of receiving the mask after being connected.

[0043] The mask cleaning rack also includes at least three protruding fixing structures 2, which are protrudingly arranged on at least two frames of the frame structure and extend into the accommodation space 100. When in use, after the mask enters the accommodation space 100, the protruding fixing structures 2 can abut between the mask and the frame structure along at least one of the length direction and the width direction of the mask, so that the mask is clamped and limited in the accommodation space 100, and the mask is spaced apart from the frame provided with the protruding fixing structures 2.

[0044] The mask cleaning rack can define a receiving space 100 to receive the mask through the frame assembly 1, and can fix the mask in the receiving space 100 through the protruding fixing structure 2 for easy movement. At the same time, the protruding fixing structure 2 can abut between the mask and the frame provided with the protruding fixing structure, so that the mask and the frame assembly 1 are spaced apart, so that the mask can be cleaned and dried in a maximum exposure manner without being blocked by the frame assembly 1, which can effectively avoid the phenomenon of residual dirt or cleaning liquid on the edge of the mask, optimize the cleaning and drying effects, and improve the yield rate of the exposure process.

[0045] Specifically, Figure 2 , Figure 4 As shown, in this embodiment, the protruding fixing structure 2 includes a first abutting portion 21, a second abutting portion 22 and a third abutting portion 23, and the first abutting portion 21, the second abutting portion 22 and the third abutting portion 23 are fixedly arranged on the frame structure. The second abutting portion 22 and the third abutting portion 23 are arranged at intervals, and the first abutting portion 21 is arranged in the interval between the second abutting portion 22 and the third abutting portion 23. When the mask is limited in the accommodation space 100, the first abutting portion 21 abuts between the frame and the mask, thereby abutting the mask along the length direction or width direction of the mask, playing a role of supporting and positioning. The second abutting portion 22 abuts against one side of the mask along the thickness direction of the mask, and the third abutting portion 23 abuts against the other side of the mask along the thickness direction of the mask, thereby limiting the mask along the thickness direction of the mask, playing a role of limiting and enhancing fixation.

[0046] More specifically, if Figure 4 As shown, the dimensions of the second abutting portion 22 and the third abutting portion 23 protruding from the frame are both larger than the dimensions of the first abutting portion 21 protruding from the frame, and the first abutting portion 21, the second abutting portion 22 and the third abutting portion 23 are combined to form a groove-shaped structure, so that the mask can be limitedly inserted between the second abutting portion 22 and the third abutting portion 23, and supported and positioned by the first abutting portion 21.

[0047] Of course, in some embodiments, only the first abutting portion 21 may be provided, and the mask may be clamped and fixed between the protruding fixing structures 2 by abutting between the frame structure and the mask. Therefore, the specific shape and structure of the protruding fixing structure 2 are not specifically limited in the present invention, as long as the mask and the frame structure can be spaced apart and the mask can be limited in the accommodating space 100.

[0048] like Figure 5 As shown, in this embodiment, the frame assembly 1 includes a first frame structure 11 and a second frame structure 12. The first frame structure 11 is in a "U" shape, and the second frame structure 12 is in a "I" shape. The second frame structure 12 is detachably connected to the opening of the "U". When the first frame structure 11 and the second frame structure 12 are not connected, the mask can enter the middle area of ​​the first frame structure 11 through the opening, and when the first frame structure 11 and the second frame structure 12 are connected, they can enclose to form the above-mentioned accommodation space 100.

[0049] When in use, first place the mask into the accommodating space 100 through the opening, and ensure that the raised fixing structure 2 firmly fixes the mask in the frame assembly 1. Next, the entire mask cleaning rack can be placed in the cleaning equipment for cleaning. Since the mask is firmly fixed, the uniformity and thoroughness of the cleaning can be ensured, while avoiding damage to the mask. After cleaning, take out the mask cleaning rack and the mask together and dry them. After drying, the mask can be easily removed by separating the first frame structure 11 and the second frame structure 12. Finally, perform simple cleaning and maintenance on the mask cleaning rack for next use.

[0050] Optionally, in some embodiments, the second frame structure 12 can also adopt a "U"-shaped structure. Of course, the first frame structure 11 can also adopt an "I"-shaped structure, or more frame structures can be combined to form a frame assembly 1. The utility model does not limit the specific number and structure of the frame structures, as long as the above-mentioned accommodating space 100 can be formed.

[0051] Continue to refer Figure 5As shown, in this embodiment, the mask cleaning rack also includes a threaded fastener 3, and the frame structures are detachably connected through the threaded fastener 3. Exemplarily, the second frame structure 12 is provided with two through holes, and the first frame structure 11 is provided with two threaded holes. The threaded fastener 3 is a bolt, and the bolt passes through the through hole and is threadedly connected to the threaded hole of the first frame structure 11 to detachably connect the first frame structure 11 and the second frame structure 12. Optionally, in some other embodiments, other methods such as snap-on connection can also be used to achieve detachable connection between frame structures, which is not specifically limited in the present utility model.

[0052] In this embodiment, if Figure 3 , Figure 5 As shown, two of the above-mentioned raised fixing structures 2 are arranged on each frame, and the four sides of the mask are respectively abutted against two raised fixing structures 2, so that the mask and each frame structure are spaced apart to avoid residual dirt and cleaning fluid.

[0053] Optionally, in some embodiments, the protruding fixing structure 2 is disposed on two opposite frames of the frame assembly 1, and the protruding fixing structure 2 includes a first abutting portion 21 extending toward the accommodating space 100. When in use, the protruding fixing structure 2 disposed on the two opposite frames of the frame assembly 1 abuts against the mask from both sides of the mask to clamp and fix the mask.

[0054] For example, refer to Figure 6 As shown, the mask is suspended for cleaning by the mask cleaning hanger, and at this time, the length direction and width direction of the mask are both located in the vertical plane. In this embodiment, the above-mentioned raised fixing structure 2 can be set only on the two frames located above and below the accommodating space 100, and each frame is provided with two raised fixing structures 2 to achieve the fixation of the mask. At this time, the frame structure members located on the left and right of the accommodating space 100 can be directly spaced from the mask, which can also achieve the effect of avoiding obstruction, and at the same time, it does not affect the clamping and fixing of the mask in the up and down directions. Of course, in some embodiments, only three raised fixing structures 2 can be set on the two frames to meet the needs of fixing the mask.

[0055] Alternatively, if Figure 7 As shown, in some embodiments, three of the above-mentioned raised fixing structures 2 are arranged on each frame, and the four sides of the mask are respectively abutted against three raised fixing structures 2, so that the mask and each frame structure are spaced apart to avoid residual dirt and cleaning fluid.

[0056] Of course, in some other embodiments, such as Figure 8As shown, each frame may be provided with a protruding fixing structure 2, and each of the four sides of the mask plate abuts against a protruding fixing structure 2, so that the mask plate and each frame structure can be spaced apart to avoid residual dirt and cleaning liquid. Preferably, a protruding fixing structure 2 is provided in the middle of each frame to achieve stable clamping and fixing.

[0057] Further optionally, if Figure 8 , Fig.10 As shown, in this embodiment, the two different structures of the above-mentioned protruding fixing structures 2 can be used at the same time. Exemplarily, the protruding fixing structure 2 located at the bottom frame includes a first abutting portion 21, a second abutting portion 22 and a third abutting portion 23, while the protruding fixing structure 2 located at the side frame only includes the first abutting portion 21.

[0058] Therefore, in the present invention, there is no limitation on the specific structure, position and number of the raised fixing structure 2, as long as it can achieve the effect of limiting fixation (or clamping fixation) and preventing obstruction.

[0059] Preferably, at least one protruding fixing structure 2 is provided on the frame structure below the accommodating space 100 to prevent the cleaning liquid that is easily accumulated on the frame structure from contacting the mask under the action of gravity, resulting in incomplete cleaning. Further preferably, in this embodiment, the mask cleaning hanger includes eight protruding fixing structures 2, and each side of the mask is abutted against at least two protruding fixing structures 2 to achieve uniform limiting fixation or uniform clamping fixation of the mask, which can not only improve the stability of fixation, but also avoid damage to the mask.

[0060] like Figure 4 , Fig.10 As shown, the frame structure member located below the accommodating space 100 is provided with a hollow groove 121, and the hollow groove 121 is arranged to penetrate along the up and down direction of the accommodating space 100. The hollow groove 121 can facilitate the dripping of the cleaning liquid and avoid the accumulation of a large amount of cleaning liquid on the frame structure member. At the same time, it is also helpful to reduce the weight of the entire mask cleaning hanger and facilitate the transfer of the mask. More preferably, the frame structure members are all provided with a hollow groove 121 to further reduce the weight of the mask cleaning hanger and to optimize the efficiency and effect of cleaning and drying. Optionally, the hollow groove 121 is provided on both sides of the protruding fixed structure 2 to avoid the accumulation and residual cleaning liquid on any side of the protruding fixed structure 2.

[0061] Preferably, in this embodiment, the mask cleaning rack further includes a bracket 4, which is connected to the frame assembly 1 by fixing screws. In addition, the bracket 4 is provided with a limiting structure 41, which is a convex or a groove, and is used to cooperate with the groove or convex on the cleaning device, so as to limit and fix the mask cleaning rack during cleaning and drying.

[0062] For example, Fig. 9 As shown, a limiting structure 41 is provided at each end of the bracket 4, and a cleaning device for cleaning the mask is provided with a slot. In the horizontal direction, the limiting structure 41 is a triangular convexity, and the inner contour of the slot is a V-shape. When the limiting structure 41 is inserted into the slot, the mask cleaning hanger can be fixed in position to prevent it from rotating, thereby improving the stability of the mask during cleaning and drying.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
