Description

Technical Field

[0001] This utility model relates to the technical field of tool polishing equipment, and in particular to a scraper polishing fixture. Background Technology

[0002] During the manufacturing process of a monitor's polarizer, its surface usually needs to be uniformly coated with a layer of liquid material, such as pressure-sensitive adhesive, polarizing film oil, polarizing film coating liquid, etc. In order to ensure that the liquid material is evenly distributed on the surface of the polarizer, a scraper with a length greater than or equal to the length of the polarizer is usually used to smooth the liquid material.

[0003] Scrapers used to level liquid materials are typically narrow blades. After a period of use, the blade edge wears down. Since polarizers are used in displays, using a worn scraper to level the liquid material results in uneven distribution, affecting the normal operation of the display. Therefore, polishing the scraper is necessary. In existing technologies, polishing scrapers usually requires workers to hold sandpaper and move it back and forth across the scraper. Because scrapers require a high degree of surface roughness, sanding takes a considerable amount of time and causes pain in the thumb, index, and middle fingers. Therefore, a polishing fixture is needed to assist workers in polishing scrapers and reduce hand fatigue. Utility Model Content

[0004] To solve the above problems, this utility model provides a scraper polishing fixture.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a scraper polishing fixture, including a base block and a limiting block disposed at the bottom of the base block. Two limiting blocks are provided and symmetrically distributed on both sides of the scraper to be polished. An installation port is provided at the intersection of the top of the limiting block and the limiting block near the other limiting block. Sandpaper for polishing the blade of the scraper to be polished is provided in the installation ports of the two limiting blocks.

[0006] By adopting the above technical solution, two limiting blocks cooperate to clamp and limit the scraper to be polished. The bottom of the sandpaper in the installation port abuts against the blade of the scraper to be polished. After the scraper is fixed, the worker can move the scraper polishing fixture as a whole by pushing the base block. In this way, the blade of the scraper is polished by sandpaper. This changes the traditional method of manually holding the sandpaper for polishing, reduces the hand fatigue of the worker holding the sandpaper for polishing, and improves the polishing efficiency of the scraper.

[0007] Furthermore, the sandpaper has a thickness of 0.5 mm and a length of 15-20 mm.

[0008] Furthermore, the main body of the sandpaper passes through the mounting opening, and both ends of the sandpaper are folded over to the top of the base block and adhered to each other.

[0009] By adopting the above technical solution, after the worker pushes the base block and makes the sandpaper grind the scraper repeatedly, it is necessary to pull the sandpaper so that the part that is not in contact with the scraper moves to the position corresponding to the scraper, so that the worker can push the base block to continue the grinding and polishing action of the scraper.

[0010] Furthermore, a bolt that fits through the base block with a clearance fit is provided on the base block, and a threaded hole for the bolt to be threaded through the limiting block is provided on the limiting block.

[0011] By adopting the above technical solution, the bolts facilitate the assembly and fixing of the base block and the limiting block by the staff.

[0012] Furthermore, the bolt is a bolt with an internal hexagonal groove, and the top of the base block is provided with an upper oblong hole for receiving the bolt head.

[0013] By adopting the above technical solution, the head of the bolt is hidden in the upper waist-shaped hole, which enhances the external aesthetics of the scraper polishing fixture.

[0014] Furthermore, multiple anti-slip protrusions are evenly fixed on the side wall of the head of the bolt.

[0015] By adopting the above technical solution, the probability of slippage during the tightening of bolts is reduced.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. In this application, the traditional method of manually holding sandpaper for polishing is changed, which reduces the hand fatigue of workers holding sandpaper during the polishing process and improves the polishing efficiency of scrapers.

[0018] 2. In this application, after the worker pushes the base block and causes the sandpaper to reciprocate and polish the scraper multiple times, it is necessary to pull the sandpaper so that the part that is not in contact with the scraper moves to the position corresponding to the scraper, so that the worker can push the base block to continue the polishing action on the scraper.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-6 As shown in the illustration, this application discloses a scraper polishing fixture, including a base block 1 and a limiting block 2 disposed at the bottom of the base block 1. Two limiting blocks 2 are symmetrically distributed on both sides of the scraper 9 to be polished. An installation port 21 is provided at the intersection of the top of the limiting block 2 and the point where the limiting block 2 intersects with the point where the limiting block 2 is located. Sandpaper 3 for polishing the blade of the scraper 9 is commonly disposed within the installation ports 21 of both limiting blocks 2. In this embodiment, the scraper is made of 304 stainless steel and has three lengths: 1950mm, 3600mm, and 3800mm, enabling the smoothing of liquid materials on three different sizes of display polarizers. The scraper is available in two widths, 64mm and 62mm, and has a thickness of 3mm. The scraper is mounted on the production line equipment to scrape the surface of the product (polarizer). It mainly uses the two R-angles 4 connecting the 3mm thick surface and the width of the scraper. The 3mm thick surface and the R-angle 4 surface are required to be polished to a mirror finish. The roughness is generally required to be Ra≤0.2μm, 0.1mm≤R-angle 4≤0.15mm. The size of the scraper and the technical effect it can achieve are not related to the technical problem to be solved by this application, and this application will not elaborate on them.

[0028] Two limiting blocks 2 cooperate to clamp and limit the scraper 9 to be polished (the side walls of the two limiting blocks 2 that are close to each other abut against the surfaces on both sides of the scraper). The bottom of the sandpaper 3 in the mounting port 21 abuts against the blade of the scraper 9 to be polished. After the scraper is fixed (the scraper can be fixed on the worktable using a clamp commonly used in existing technology), the operator can move the scraper polishing fixture as a whole by pushing the base block 1. In this way, the blade of the scraper is polished by the sandpaper 3. This changes the traditional method of manually holding the sandpaper 3 for polishing, reduces the hand fatigue of the operator holding the sandpaper 3 for polishing, and improves the polishing efficiency of the scraper.

[0029] The sandpaper 3 is 0.5mm thick and 15-20mm long. The main body of the sandpaper 3 passes through the mounting opening 21, and both ends of the sandpaper 3 are folded over to the top of the base block 1 and fit together. After the worker pushes the base block 1 and the sandpaper 3 reciprocates and polishes the scraper multiple times, the sandpaper 3 needs to be pulled so that the part that was not in contact with the scraper moves to the position corresponding to the scraper, so that the worker can push the base block 1 to continue the polishing action on the scraper.

[0030] To facilitate fixing the limiting block 2 to the bottom of the base block 1, a bolt 7 with clearance fit is provided through the base block 1, and a threaded hole 22 for threaded connection of the bolt 7 is provided through the limiting block 2. In this embodiment, each limiting block 2 has two bolts 7.

[0031] To enhance the external aesthetics of the scraper polishing fixture, bolt 7 is a bolt with an internal hexagonal groove, and the top of the base block 1 is provided with an upper oblong hole 11 for accommodating the head of bolt 7. To reduce the probability of slippage during the tightening of bolt 7, multiple anti-slip protrusions 8 are evenly fixed on the side wall of the head of bolt 7.

[0032] The working principle of the scraper polishing fixture in this embodiment is as follows: two limiting blocks 2 cooperate to clamp and limit the scraper 9 to be polished. The bottom of the sandpaper 3 in the mounting port 21 abuts against the blade of the scraper 9 to be polished. After the scraper is fixed, the operator can move the scraper polishing fixture as a whole by pushing the base block 1. In this way, the blade of the scraper is polished by the sandpaper 3. This changes the traditional method of manually holding the sandpaper 3 for polishing, reduces the hand fatigue of the operator in holding the sandpaper 3 for polishing, and improves the polishing efficiency of the scraper.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
