Description

An electronic paper surface cleaning mechanism that facilitates easy replacement of lint-free cloths. Technical Field

[0001] This invention relates to the field of electronic paper surface cleaning technology, and more specifically to an electronic paper surface cleaning mechanism that facilitates the replacement of lint-free cloths. Background Technology

[0002] Electronic paper, also known as digital paper, is an ultra-thin and ultra-light display screen, as thin, soft, and erasable as paper. In actual production, appropriate cleaning methods and equipment are selected based on the material, structure, and cleaning requirements of the electronic paper. Surface cleaning usually needs to be carried out in multiple stages of the production process to ensure the surface quality and performance of the electronic paper.

[0003] Surface cleaning is a crucial step in the production of electronic paper. Precision electronic cleaning agents can be used to clean the surface, effectively removing fingerprints, oil stains, dust particles, and other contaminants. However, it's important to note that to prevent the cleaning agent from seeping into the electronic paper, it's generally not sprayed directly onto the screen. The correct method is to spray a suitable amount of cleaning agent onto a microfiber lint-free cloth and then wipe the screen. However, lint-free cloths need to be manually replaced after multiple uses, which is cumbersome and disrupts automated production cycles. Summary of the Invention

The locking plate 134 is used to fix the external lint-free cloth.

[0037] It also includes a placement part 3, which includes a placement box 31, and the placement box 31 is located directly above the wiper 132. The placement box 31 is fixedly connected to the top of the base 11 by a support frame 32 provided on its outer surface. A square hole 33 is provided on the side of the placement box 31. A slide rail 34 is fixedly connected to the side of the placement box 31 near the square hole 33, and an electric push rod 35 is slidably connected inside the slide rail 34. The output end of the electric push rod 35 is fixedly connected to a push plate 36 that slides against the inner wall of the square hole 33.

[0038] The top of the base 11 is provided with a drive box 14 that is connected to the main shaft 131 for transmission, and the frame 12 is rotatably mounted with ball bearings 122 via a hemispherical rod 121 provided on its outer surface.

[0039] The wiper 132 includes a wiping rod 1321, an outer rod 1322 is fixedly connected to the outer surface of the wiping rod 1321, and a sleeve 1311 is fixedly connected to the outer surface of the main shaft 131, which slides with the outer surface of the outer rod 1322. A strong spring assembly 1323 is provided at the end of the outer rod 1322 away from the wiping rod 1321 and connected to the inner wall of the sleeve 1311.

[0040] The outer circumferential surface of the wiping rod 1321 is provided with an arc-shaped groove 13211 that communicates with the engaging groove 133. The wiping rod 1321 is slidably connected to a reciprocating block 13213 through an internal cavity 13212.

[0043] Referring to Figure 1-8, surface cleaning is a crucial step in the production of electronic paper. When cleaning the surface of electronic paper, a precision electronic cleaning agent can be used. This agent effectively removes fingerprints, oil stains, dust particles, and other contaminants. However, it's important to note that to prevent the cleaning agent from penetrating the interior of the electronic paper, it should not be sprayed directly onto the screen. The correct method is to spray an appropriate amount of cleaning agent onto a microfiber lint-free cloth and then wipe the screen. However, the lint-free cloth needs to be manually replaced after multiple uses, which is cumbersome and disrupts the automated production cycle.

[0044] To overcome the aforementioned defects, this invention designs an electronic paper surface cleaning mechanism that facilitates the replacement of the lint-free cloth.

[0045] Automated feeding of cleanroom wipes:

[0046] The cleaning mechanism 13 in this application adopts a separate structure, mainly including wipers 132 and locking plates 134. Four sets of wipers 132 are equidistantly distributed on the outer circumference of the main shaft 131. Initially, the locking plates 134 are stacked in the placement box 31 of the placement section 3. Because the locking plates 134 adopt a semi-circular design (range exceeding 180 degrees), there is still a large "gap" between the stacked locking plates 134. At the same time, the upper and lower ends of the placement box 31 are open, and the inner side of the bottom end of the placement box 31 adopts a "convex surface" design, which effectively prevents the stacked locking plates 134 from falling freely. Next, the cleanroom wipes are laid flat on the support 23 of the feeding section 2. With the help of the torsion spring, the pressing plate 24 presses the cleanroom wipes on both sides. Then, the drive unit 21 drives the rotating disk 22 to rotate, causing the pressed cleanroom wipes to rotate synchronously and intermittently (the external spray head adds an appropriate amount of cleaning agent to the pressed cleanroom wipes). When the cleanroom wipe rotates to directly below the placement box 31, the placement box 31, the cleanroom wipe, and the wiper 132 are arranged sequentially from top to bottom with small distances between them. Then, the PLC controls the slide rail 34 to drive the electric push rod 35 and the push plate 36 to move towards the locking plate 134 simultaneously until the push plate 36 slides into the adjacent "gap" between the last and second-to-last locking plates 134. Immediately afterwards, the output end of the electric push rod 35 drives the push plate 36 to move downward (both sets of electric push rods 35 move simultaneously), driving the last locking plate... 134 slides downwards along the inner wall of the placement box 31 until the last locking plate 134 disengages from the "convex surface" on the inner side of the bottom of the placement box 31 (the locking plate 134 undergoes elastic deformation). The pushing plate 36 drives the last locking plate 134 to move downwards quickly and contact the cleanroom cloth. The cleanroom cloth is evenly stressed and quickly disengages from the pressing plate 24 until the locking plate 134 drives the cleanroom cloth to quickly snap into the locking groove 133 (short-distance displacement), realizing the automated feeding of the cleanroom cloth, which is suitable for automated production. The locking plate 134 and the locking groove 133 are combined into a whole. Then, the drive box 14 is started, and the servo motor inside drives the main shaft 131 to rotate around the inside of the frame 12, driving the wiper 132 containing the cleanroom cloth and the locking plate 134 to rotate clockwise to the bottom. It should be emphasized that the cleanroom cloth after a single switch can be used for a batch of electronic paper.

[0047] Advantages of locking plate 134:

[0048] Firstly, because the locking plate 134 adopts a semi-circular design, the thickness of the locking plate 134 gradually decreases from the middle to the outside. The locking plate 134 can automatically drive the lint-free cloth to quickly snap into the locking groove 133. The locking plate 134 covers an area of ​​more than 180 degrees, so the locking plate 134 cannot be disengaged from the locking groove 133.

[0049] Secondly, the inner wall of the locking plate 134 is fixedly connected with Velcro 1341, which increases the friction between the locking plate 134 and the lint-free cloth, which not only facilitates lint-free wiping, but also makes it convenient for the lint-free cloth to detach synchronously with the locking plate 134.

[0050] Thirdly, the locking plates 134 are fixedly connected to each other with a pressing rod 1342 that fits against the inner wall of the arc groove 13211, so that the two sets of locking plates 134 are combined into a whole. When pressure is applied to the cleanroom cloth, the cleanroom cloth is subjected to uniform force, and the pressing rod 1342 can press the cleanroom cloth tightly to prevent the cleanroom cloth from curling and detaching during the wiping process.

[0051] Fourthly, the clamping rod 1342 drives the cleanroom cloth to be inserted into the arc-shaped groove 13211, and the cleanroom cloth is in a "tight state" all around. The arc-shaped groove 13211 is designed to allow the cloth to slide out quickly along the arc surface of the groove 13211.

[0052] Cleaning electronic paper surface with a lint-free cloth:

[0053] The external conveyor unit carries the electronic paper directly below the wiper 132. Since the external rod 1322 can slide slightly along the inside of the sleeve 1311, the surface of the electronic paper can be wiped and cleaned in conjunction with the pressed lint-free cloth (containing cleaning agent) while avoiding excessive compression of the electronic paper.

[0054] Automated feeding of cleanroom wipes:

[0055] After a batch of electronic paper is cleaned, it needs to be replaced. Then, the main shaft 131 rotates clockwise, driving the wiper 132 containing the dirty lint-free cloth and the locking plate 134 to rotate upwards simultaneously. When the hemispherical ball 13214 on the wiper 132 rotates and contacts the ball bearing 122, the ball bearing 122 rotates under the action of friction (to avoid long-term force on a single point). At the same time, the ball bearing 122 pushes the hemispherical ball 13214, causing the reciprocating block 13213 to slide inward along the inner wall of the built-in cavity 13212 (the first spring 13215 undergoes elastic deformation under pressure). The inclined surface of the reciprocating block 13213 drives two sets of L-shaped... The inclined blocks 13216 slide outward synchronously (the second spring 13217 is stretched and undergoes elastic deformation). The two sets of L-shaped inclined blocks 13216 slide outward to open the two ends of the locking plate 134 (the thickest part of the locking plate 134). The locking plate 134 undergoes elastic deformation until it is opened to the near value. At this time, the clamping rod 1342 slides to the side of the arc groove 13211. Under the elastic force of the spring plate 1343, the locking plate 134 quickly recovers and detaches and pops outward. With the help of the Velcro 1341, the dirty cleanroom cloth falls into the external collection box, realizing the automated recycling of cleanroom cloth, which is suitable for automated production.
