Description

Technical Field

[0001] This utility model relates to the field of mask fixture technology, specifically a general-purpose adhesive application fixture. Background Technology

[0002] In the photomask production industry, surface cleaning, adhesive coating, and drying are essential processing steps. Due to the limitations of the frames in our cleaning, adhesive coating, and baking machines, the smallest photomask size we can produce is 800*920mm. Our existing adhesive coating fixtures cannot be used on every machine, leading to manual handling of masks and fixture changes during production, which can contaminate the masks and affect production efficiency. Subsequent drying and cleaning of the masks are necessary, but conventional adhesive coating fixtures are unsuitable for use with drying and cleaning equipment. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a universal adhesive application fixture, which solves the problem of limited applicability of existing mask adhesive application fixtures and the inconvenience of daily handling of the fixture due to its weight limitations.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A general-purpose adhesive applicator includes a fixture body and a mask placement groove formed in the middle of the fixture body. The bottom of the placement groove has a hollowed-out groove, and a supporting edge is provided around the bottom of the placement groove to support the placement of the mask. A sealing groove is provided on the supporting edge, and a sealing ring is provided in the sealing groove.

[0008] Preferably, the clamp body is 800mm wide and 920mm long, the placement slot is 524mm wide and 804mm long, and the hollow slot is 494mm wide and 774mm long.

[0009] Preferably, the placement groove is 105mm deep and the support edge is 4mm high.

[0010] Preferably, the diameter of the sealing ring is not less than 5mm and the protruding portion after being placed in the sealing groove is not less than 1mm.

[0011] Preferably, the fixture body is integrally formed from aluminum alloy material.

[0012] (III) Beneficial Effects

[0013] This utility model has the following beneficial effects:

[0014] This universal adhesive coating fixture features a hollowed-out center with supporting edges around the perimeter for holding the mask to be produced. The trapezoidal shape with height differences is designed based on the mask's thickness, ensuring the mask's upper surface and the fixture's upper surface are on the same plane. This guarantees a good fit between the mask and the fixture without affecting the process, allowing it to conform to the existing equipment and procedures in subsequent cleaning and baking processes. The sealing rings on the supporting edges, in conjunction with the vacuum pump of the adhesive coating equipment, ensure the mask's stability during high-speed rotation, thus improving production safety. The fully hollowed-out center of the fixture allows the back spray system of the cleaning equipment to clean the lower surface of the mask to a certain extent, improving product cleanliness. It also ensures more even heating of the mask placed and fixed within the fixture during subsequent baking, improving product precision. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1This utility model provides a technical solution: a general-purpose adhesive applicator, including an applicator body 1 and a mask placement groove 2 opened in the middle of the applicator body 1. The bottom of the placement groove 2 is provided with a hollow groove 3. The bottom of the placement groove 2 is provided with a support edge 4 around the hollow groove 3 to support the placement of the mask. A sealing groove 5 is provided on the support edge 4, and a sealing ring 6 is provided in the sealing groove 5.

[0022] This invention features a hollowed-out fixture body 1 with surrounding support edges 4 for holding the mask to be produced. The trapezoidal shape with height difference is designed based on the mask's thickness to ensure the upper surface of the mask and the upper end of the fixture body 1 are on the same plane. This guarantees a good fit between the mask and the fixture without affecting the process, allowing it to conform to the existing equipment and process height during subsequent cleaning and baking. The sealing ring 6 on the support edges 4 works in conjunction with the vacuum pump of the adhesive coating equipment to ensure the stability of the mask's adhesion and fixation during high-speed rotation of the adhesive coating equipment, thereby improving production safety. The fully hollowed-out design of the fixture body 1 allows the back spray device of the cleaning equipment to clean the lower end of the mask to a certain extent, improving product cleanliness. Furthermore, it ensures more even heating of the mask placed and fixed within the fixture body 1 during subsequent baking, improving product precision.

[0023] In this embodiment, the fixture body 1 is 800mm wide and 920mm long, the placement slot 2 is 524mm wide and 804mm long, and the hollowed-out slot 3 is 494mm wide and 774mm long. The overall dimensions of the fixture body 1 are 800*920mm, corresponding to the minimum size of the production equipment, allowing it to participate normally in the production process of subsequent equipment. The centrally located placement slot 2 is 524*804mm in size, corresponding to the mask plate size of 520*800mm, with a 2mm allowance on each side for convenient plate handling. The hollowed-out design allows the back spray device of the cleaning equipment to perform a certain degree of cleaning on the mirror surface of the mask plate, improving the cleanliness of the product; it also allows the mask plate to be heated more evenly in the baking equipment, improving product precision.

[0024] In this embodiment, the placement groove 2 is 105mm deep and the support edge 4 is 4mm high.

[0025] In this embodiment, the sealing ring 6 has a diameter of not less than 5mm and protrudes not less than 1mm after being placed in the sealing groove 5. The design of the sealing ring 6, in conjunction with the vacuum pump of the adhesive coating equipment, ensures the airtightness of the mask plate when it is fixed at high speed by the adhesive coating equipment, thereby improving the safety of the production process.

[0026] In this embodiment, the fixture body 1 is integrally machined from aluminum alloy. The fixture body 1 is made entirely of aluminum alloy. The main consideration for choosing aluminum alloy is its stability and plasticity, small deformation, stable structure, and light weight, which greatly facilitates the operator's operation of picking up and placing the fixture.

[0027] Existing adhesive application equipment uses the following method: Figure 4 The fixture body with grid grooves shown is heavy and has a high manufacturing cost, making it inconvenient to replace the fixture body in subsequent processes. At the same time, due to the obstruction of the grid groove edges, it is inconvenient for cleaning and drying equipment to clean and dry the lower end face of the mask inside the fixture body. In addition, water stains are easily left on the end face of the mask during the cleaning process. Therefore, conventional fixtures with grid grooves are not suitable for use with drying and cleaning equipment.
