Description

Technical Field

[0001] This utility model belongs to the technical field of glue applicator, and in particular relates to a slit scraper adjustment device for a glue applicator. Background Technology

[0002] A photomask, also known as a photomask or photomask, uses quartz glass as a substrate. First, a layer of chromium is deposited on the quartz glass substrate. Then, photoresist is coated on the chromium layer to make it a photosensitive material. The designed circuit pattern is then exposed to light by an electron laser device. The exposed areas are developed and etched onto the chromium to form the circuit pattern, creating a photomask master similar to a negative after exposure. Photomasks are an indispensable component in the production of LCD panels, where LCD panel manufacturers use them for exposure to obtain the desired patterns.

[0003] Existing devices, such as the adjustment device for the slit scraper of a glue applicator shown in patent publication number CN212596762U, include a glue applicator and a slit scraper arranged on the glue applicator. Although the slit scraper width can be adjusted within a small range by sliding clamps when the above patent is in use, the clamps are too long when a larger range of adjustment is required. When coating large-size photomasks, the clamps may extend too far, affecting the space occupied by the glue applicator.

[0004] In addition, due to the relative sliding between the fixture and the slit scraper, gaps may exist between them. During coating, photoresist may escape from the gaps, affecting the coating effect and causing waste.

[0005] To address this issue, we propose a slit scraper adjustment device for an adhesive applicator. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art where the excessive extension of the clamp affects the space occupied by the glue applicator, and to propose a slit scraper adjustment device for the glue applicator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A slit scraper adjustment device for an adhesive applicator includes an adhesive applicator and a slit scraper mounted on the adhesive applicator, and further includes at least one material-stopping unit detachably connected to the bottom surface of the slit scraper;

[0009] The material blocking unit includes a base plate that fits the bottom surface of the slit scraper. The base plate has clamps that are fixedly connected to the outside of the slit scraper on both sides. The top surface of the base plate is fixed with a sealing component that is inserted into the slit scraper. The slit scraper has multiple threaded holes on both sides. The clamps are detachably connected to the slit scraper by bolts that fit into the threaded holes.

[0010] Preferably, the clamping plates of adjacent material-blocking units are provided with mutually cooperating protrusions and grooves.

[0011] Preferably, auxiliary blocks are fixedly connected to both sides of the lower part of the slit scraper, and the bottom surface of the auxiliary blocks is flush with the base plate. The auxiliary blocks are provided with auxiliary grooves for matching protrusions on both sides.

[0012] Preferably, the sealing assembly includes an insert block fixedly connected to the top surface of the base plate, and the insert block is inserted into the slit scraper, with a sealing ring fixedly provided on the side of the insert block.

[0013] Preferably, the side of the sealing ring facing the auxiliary block on the same side is lower than the other side of the sealing ring.

[0014] Preferably, the insert block is fixedly connected to a locking block with a matching sealing ring on both sides parallel to the slit scraper.

[0015] In summary, the technical effects and advantages of this utility model are as follows: Compared with existing devices, this slit scraper adjustment device for a glue applicator achieves a detachable and fixed connection between the clamping plate and the slit scraper through bolts and threaded holes, and achieves partial material blocking of the material outlet of the scraper below through the base plate and the sealing component, thereby realizing the adjustment of the slit scraper width. Compared with existing devices, it avoids the problem of long clamp length due to the need for a large adjustment range, which affects space occupation, and improves flexibility and applicability.

[0016] Furthermore, the detachable fixed connection of the clamp to the slit scraper achieves relative stillness between the sealing component and the slit scraper, which improves the sealing and coating effects and reduces waste compared to the existing sliding design.

[0017] By arranging and combining multiple baffle units, the slit scraper is divided into multiple segments, thereby enabling simultaneous coating of multiple small-sized photomasks and improving work efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3 A slit scraper adjustment device for an adhesive applicator includes an adhesive applicator 1 and a slit scraper 2 mounted on the adhesive applicator 1, and further includes at least one baffle unit 3 detachably connected to the bottom surface of the slit scraper 2. The adhesive applicator 1 and the slit scraper 2 are prior art and will not be described in detail.

[0026] The material blocking unit 3 includes a base plate 4 that fits the bottom surface of the slit scraper 2. The base plate 4 has clamping plates 5 that are fixedly connected to the outside of the slit scraper 2 on both sides. The top surface of the base plate 4 is fixedly provided with a sealing component that is inserted into the slit scraper 2. The slit scraper 2 has multiple threaded holes 6 on both sides. The clamping plates 5 are detachably connected to the slit scraper 2 by bolts 7 that fit into the threaded holes 6.

[0027] When coating large-size photomasks, the slit scraper adjustment device of this coating machine only requires turning on the coating machine 1, and the slit scraper 2 can apply photoresist onto the photomask.

[0028] When coating a medium-sized photomask, one or more baffle units 3 are selected according to the size of the photomask and arranged and fixed sequentially from both sides of the slit scraper 2 toward the middle. The baffle units 3 are fixed by being threaded into the threaded holes 6 by bolts 7. At this time, the sealing component is inserted into the slit scraper 2, and the photoresist flows out only from the middle of the slit scraper 2, so that the medium-sized photomask can be coated.

[0029] Reference Figure 5 When coating small-sized photomasks, multiple photomasks can be coated simultaneously. Simply place adjacent baffle units 3 at a distance from each other, and the photoresist flows out between the adjacent baffle units 3 during coating, thus coating multiple small-sized photomasks simultaneously.

[0030] Reference Figure 1-3 The clamping plates 5 of adjacent material blocking units 3 are provided with mutually cooperating protrusions 8 and grooves 9. The connection between adjacent clamping plates 5 is achieved by the protrusions 8 and the grooves 9, thereby improving the connection stability and ease of connection between adjacent material blocking units 3.

[0031] Auxiliary blocks 10 are fixedly connected to both sides of the lower part of the slit scraper 2, and the bottom surface of the auxiliary blocks 10 is flush with the base plate 4. Auxiliary grooves 11 are provided on both sides of the auxiliary blocks 10 to cooperate with the protrusions 8. Through the auxiliary blocks 10 and auxiliary grooves 11, in cooperation with the protrusions 8, a function similar to that of the protrusions 8 and grooves 9 can be achieved, improving the connection stability and convenience of the material blocking units 3 on both sides.

[0032] Reference Figure 3-4 The sealing assembly includes an insert block 12 fixedly connected to the top surface of the base plate 4, and the insert block 12 is inserted into the slit scraper 2. A sealing ring 13 is fixedly provided on the side of the insert block 12. The sealing of the sealing assembly is achieved by the insert block 12 and the sealing ring 13, preventing photoresist from escaping from the gaps.

[0033] Due to the width of the sealing ring 13 itself, it may be difficult to install adjacent baffle units 3 in place. The side of the sealing ring 13 facing the auxiliary block 10 on the same side is lower than the other side of the sealing ring 13. During installation, the sealing rings 13 of adjacent baffle units 3 are staggered to facilitate installation.

[0034] To prevent the sealing ring 13 from shifting due to external forces during use, the insert block 12 is fixedly connected to the two sides of the slit scraper 2 with a locking block 14 that matches the sealing ring 13, and the locking block 14 limits the sealing ring 13.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
