Abstract
Description
Technical Field
[0001] This utility model relates to the field of target material production technology, and in particular to an indium coating tool. Background Technology
[0002] For rotating targets such as ITO and AZO, the target tube needs to be produced first, and then bound to the back tube. The binding process involves first coating the outside of the back tube with indium, then coating the inside of the target tube with indium, and then fitting the indium-coated target tube onto the outside of the back tube and pouring molten indium between the two. After the indium solidifies, the binding of this section of the target tube is completed. When coating the inside of the target tube with indium, the target tube is usually placed on two rollers. The rotation of the rollers drives the target tube to rotate (to prevent the target tube from cooling down too quickly, the target tube and rollers can be placed in an electric furnace with one end open, or a heating device can be used to heat the outside of the target tube). Then, an ultrasonic indium coating machine is used to coat the indium, but the ultrasonic indium coating machine is relatively expensive. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an indium coating tool to address the above-mentioned technical deficiencies.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an indium coating tool, including a handle, which is disposed at one end of a main body. The bottom surface of the main body is an arc surface with a diameter equal to the inner diameter of the target tube. A notch is provided on one side of the main body. A brushing part is provided in the middle of the bottom surface of the main body. The bottom surface of the brushing part is an arc surface coaxial with the bottom surface of the main body with a diameter smaller than the inner diameter of the target tube. A front scraper group and a rear scraper group are sequentially arranged on the side of the main body away from the notch, and the bottom surfaces of both groups can contact the inner wall of the target tube. Both the front scraper group and the rear scraper group include multiple scrapers, and the scrapers on both groups are staggered in the length direction of the main body.
[0005] To further optimize this technical solution, a compression part is provided on the side of the coating part near the notch, and the bottom surface of the compression part gradually decreases in distance from the bottom surface of the main body in the direction from near to far from the notch.
[0006] To further optimize this technical solution, the front scraper assembly and the rear scraper assembly are mounted on the scraping component. The scraping component is also provided with an insertion port that extends through both sides. The main body is provided with a threaded hole on the side near the scraping component. After the bolt passes through the insertion port, it connects with the threaded hole to fix the scraping component to the main body.
[0007] To further optimize this technical solution, a grip is provided at the end of the handle away from the main body.
[0008] Compared with the prior art, the present invention has the following advantages: a notch is provided on one side of the main body, a brushing part is provided in the middle of the bottom surface of the main body, and a front scraper group and a rear scraper group are arranged in sequence on the side of the main body away from the notch, so that the indium melt can be coated on the inner wall of the target tube.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0016] Detailed implementation method: combined with Figure 1-5As shown, an indium coating tool includes a handle 1, which is disposed at one end of a main body 2. The bottom surface of the main body 2 is an arc surface with a diameter equal to the inner diameter of a target tube 4. A notch 22 is provided on one side of the main body 2. Due to the presence of the notch 22, side plates 21 are formed at both the front and rear ends of the side of the main body 2 with the notch 22. A coating part 24 is provided in the middle of the bottom surface of the main body 2. The bottom surface of the coating part 24 is an arc surface coaxial with the bottom surface of the main body 2, and the diameter of the arc surface is smaller than the inner diameter of the target tube 4. Preferably, the diameter of the bottom arc surface of the coating part 24 is 0.4-1 mm smaller than the inner diameter of the target tube 4, so that there is a gap of 0.2-0.5 mm between the bottom surface of the coating part 24 and the inner wall of the target tube 4 during use. A front scraper assembly 32 and a rear scraper assembly 31 are sequentially provided on the side of the main body 2 away from the notch 22, and the bottom surfaces of the two can be aligned with the inner wall of the target tube 4. The inner wall of the target tube 4 is in contact with the target tube 4. The bottom surface of both is preferably an arc surface coaxial with the bottom surface of the main body 2, and the diameter of this arc surface is equal to the inner diameter of the target tube 4. Both the front scraper group 32 and the rear scraper group 31 include multiple scrapers, and the scrapers on both are staggered along the length direction of the main body 2 (the length direction of the main body 2 is parallel to the length direction of the handle 1). The multiple scrapers on the front scraper group 32 can be arranged in a straight line with gaps between adjacent scrapers, and the multiple scrapers on the rear scraper group 31 can also be arranged in a straight line with gaps between adjacent scrapers. Except for one or two scrapers located at the edge, the scrapers on the front scraper group 32 are located between two adjacent scrapers on the rear scraper group 31. Preferably, the width of the scrapers on the front scraper group 32 is not less than the distance between two adjacent scrapers on the rear scraper group 31. The distance between the front scraper group 32 and the rear scraper group 31 is... Figure 5 There are certain intervals in the left and right directions. When using, combine... Figure 5 As shown, the heated target tube 4 is placed horizontally on two rollers 5. The rollers 5 rotate to drive the target tube 4 to rotate counterclockwise. The main body 2 of the tool is inserted into the target tube 4 (it can be located at the rear or front end first), and the bottom surface of the main body 2 is made to fit against the inner wall of the lower part of the target tube 4. Then, a certain amount of indium molten liquid is put into the notch 22. Under the action of gravity and adhesion, the indium molten liquid will enter the lower part of the coating part 24 and form a thin layer of indium molten liquid on the inner wall of the target tube 4. The front scraper group 32 and the rear scraper group 31 can scrape the indium molten liquid layer, thereby promoting the wetting of the indium molten liquid with the inner wall of the target tube 4. After the target tube 4 rotates several times (usually about 5 times), the inner wall of the target tube 4 where the main body 2 is located is coated with indium. At this time, the main body 2 can be moved a certain distance along the length of the target tube 4 to continue the indium coating work until the inner wall of the target tube 4 is coated with indium. During this process, it is necessary to observe the condition of the indium melt in the gap 22 in real time. If there is a small amount of indium melt remaining, it is necessary to add an appropriate amount of indium melt into the gap 22 in a timely manner.
[0017] Furthermore, a compression section 23 is provided on the side of the coating section 24 near the notch 22. The bottom surface of the compression section 23 gradually decreases in distance from the bottom surface of the main body 2 in the direction from near to far from the notch 22. The presence of the compression section 23 makes it easier for the indium molten liquid in the notch 22 to enter below the coating section 24.
[0018] Furthermore, the front scraper assembly 32 and the rear scraper assembly 31 are mounted on the scraper component 3. The scraper component 3 is also provided with an insertion port 33 extending through both sides. The main body 2 is provided with a threaded hole on the side near the scraper component 3. After the bolt passes through the insertion port 33, it connects with the threaded hole to fix the scraper component 3 to the main body 2, realizing a detachable connection between the scraper component 3 and the main body 2. The length of the insertion port 33 is greater than the diameter of the threaded hole. When the scraper wears a lot, the position of the scraper component 3 can be adjusted downwards.
[0019] Furthermore, a handle 11 is provided at the end of the handle 1 away from the main body 2, which makes it convenient for the operator to hold.
[0020] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
