Description

Technical Field

[0001] The present invention relates to the technical field of electronic paper processing equipment, and in particular to an alternating electronic paper cleaning device. Background Art

[0002] With the development of electronic technology, the concept of electronic paper (e-paper), also known as digital paper, has emerged. It is an ultra-thin, ultra-light display that can be understood as "paper-thin, flexible, and rewritable." E-paper is increasingly being used in a variety of fields, including retail, education, healthcare, and office work. Its low-carbon, environmentally friendly, eye-friendly, and rewritable properties make it an ideal alternative to traditional paper. However, during the processing of e-paper, its surface inevitably becomes contaminated with dust, stains, and other contaminants. This not only affects the display quality but can also negatively impact its lifespan and performance.

[0003] Currently, there are a variety of electronic paper cleaning devices on the market, but most of these devices share a common problem: they can only clean the electronic paper once. When cleaning multiple sheets of electronic paper continuously, this single cleaning method often fails to completely remove dust and stubborn stains from the surface of the electronic paper, resulting in limited effectiveness. Furthermore, single cleaning can result in uneven cleaning, with some areas being over-cleaned and others under-cleaned, thus affecting the overall display quality of the electronic paper and hindering subsequent processing steps. Therefore, an alternating electronic paper cleaning device is provided to address this technical problem. Summary of the Invention

[0004] The purpose of the present invention is to provide an alternating electronic paper cleaning device to address the shortcomings of the prior art, so as to solve the technical problem that the existing electronic paper cleaning device can only clean the electronic paper once, resulting in poor cleaning effect.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] An alternating electronic paper cleaning device includes a support housing, a support base disposed at the bottom of the support housing, a rotating base rotatably disposed on the support base with its axis vertically arranged, and a plurality of lifting bases movably disposed up and down on the sides of the rotating base, the lifting bases being arranged in an array equidistantly around the axis of rotation of the rotating base; each lifting base being rotatably disposed with a transversely arranged rotating shaft, the axis of the rotating shaft being perpendicular to the axis of rotation of the rotating base, and a supporting mechanism for supporting the electronic paper being mounted at the end of each rotating shaft;

[0007] The supporting mechanism includes a support frame having a vertically arranged guide groove formed therein. The guide groove is provided with a pair of supporting plates arranged up and down and capable of sliding toward or away from each other. The supporting plates are used to support the electronic paper. The pair of supporting plates are symmetrically arranged about the axis of the rotating shaft, and when the two supporting plates slide toward each other, they can clamp the electronic paper.

[0008] A first cleaning table for holding the lowered carrier plate is installed in the supporting shell, the top surface of the first cleaning table is the first cleaning station, and a first placement groove for positioning the carrier plate is formed on the top surface of the first cleaning table, and a surface middle wiping mechanism for performing a first cleaning on the electronic paper placed at the first cleaning station is provided on the side of the first cleaning table; a second cleaning table for holding the lowered carrier plate is installed in the supporting shell, the top surface of the second cleaning table is the second cleaning station, and a second placement groove for positioning the carrier plate is formed on the top surface of the second cleaning table, and a surface edge wiping mechanism for performing a second cleaning on the electronic paper placed at the second cleaning station is provided on the side of the second cleaning table.

[0009] The beneficial effects of the present invention are as follows: when in use, after the electronic paper to be cleaned is placed on the supporting plate placed below, the rotating seat is controlled to rotate 90 degrees on the supporting seat, so that the supporting plate can be driven to be placed just above the first placement slot, and then the lifting seat is controlled to move downward to drive the supporting plate below to be placed in the first placement slot, so that the supporting plate is supported by the first cleaning table and positioned by the first placement slot, so that the electronic paper placed on the supporting plate is placed in the first cleaning station, and finally the middle surface wiping mechanism is operated to perform the first cleaning treatment on the electronic paper placed in the first cleaning station, thereby cleaning the middle position of the surface of the electronic paper; after the cleaning is completed, the middle surface wiping mechanism stops running and resets, and then the lifting seat is controlled to move upward The lifting seat is controlled to move downward again to drive the lower supporting plate to be placed in the second placement slot, so that the supporting plate is supported by the first cleaning table and positioned by the first placement slot, so that the electronic paper placed on the supporting plate is placed in the second cleaning station, and finally the surface edge wiping mechanism is operated to perform a second cleaning process on the electronic paper placed in the second cleaning station, and clean both edges of the surface of the electronic paper; the above cleaning process is repeated to realize two automatic cleaning processes on different electronic papers in an orderly manner, thereby improving the cleaning efficiency of the electronic paper.

[0010] In addition, after the electronic paper has undergone the second cleaning process, the lifting seat is first controlled to reset upward, and then the upper and lower supporting plates are controlled to move in a direction close to each other to clamp the electronic paper. Subsequently, the rotating seat is controlled to rotate 90°, and during the rotation process, the rotating shaft is driven to rotate 180°, so that the clamped electronic paper is flipped 180°, and the electronic paper is turned over. Then the upper and lower supporting plates are moved in a direction away from each other to loosen the electronic paper. At this time, the side of the electronic paper to be cleaned faces up, and the side that has been cleaned faces down. After turning over, the other side of the electronic paper undergoes two cleaning processes, which realizes automatic cleaning of both sides of the electronic paper, thereby improving the cleaning effect of the electronic paper.

DETAILED DESCRIPTION

[0026] The following is a detailed description of an alternative electronic paper cleaning device according to the present invention with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, an embodiment of an alternating electronic paper cleaning device of the present invention includes a base 1 and a support shell 2 mounted on the base 1, wherein a support base 4 is provided at the bottom of the support shell 2, and a rotating base 5 with a vertically arranged axis is rotatably provided on the support base 4, and a plurality of lifting bases 6 are provided on the side of the rotating base 5 so as to move up and down. The lifting bases 6 are arranged in an equidistant array around the axis of rotation of the rotating base 5, and four lifting bases 6 are provided so that the angle between adjacent lifting bases 6 is 90°; when the rotating base 5 is controlled to rotate on the support base 4, the four lifting bases 6 can be driven to rotate around the axis of rotation of the rotating base 5, and the lifting bases 6 can also move up and down on the side of the rotating base 5.

[0028] Among them, a horizontally arranged rotating shaft 7 is rotatably provided on each lifting seat 6, and the axis of the rotating shaft 7 is perpendicular to the axis of rotation of the rotating seat 5. The rotating seat 5 is cylindrical, and the direction of the axis of the rotating shaft 7 is consistent with the radial direction of the rotating seat 5. A carrying mechanism 8 for carrying electronic paper is installed at the end of each rotating shaft 7; after the electronic paper is placed on one of the carrying mechanisms 8, the rotating seat 5 can be controlled to rotate 90° on the supporting seat 4, thereby driving the carrying mechanism 8 carrying the electronic paper to rotate 90°, and then the lifting seat 6 is controlled to move downward, which can drive the electronic paper to the first cleaning position, and perform the first cleaning treatment on the electronic paper. While cleaning, the next piece of electronic paper is placed on the next carrying mechanism 8; after the electronic paper is cleaned for the first time, the lifting seat 6 is controlled to reset upward, and the lifting seat 6 is controlled again to move downward. The rotating base 5 rotates 90 degrees on the support base 4 and controls the lifting base 6 to move downward. The carrying mechanism 8 carries the electronic paper after the first cleaning process to the second cleaning position for the second cleaning process. However, the electronic paper on the next carrying mechanism 8 is moved to the first cleaning position. The first cleaning process cleans the center of the electronic paper surface, and the second cleaning process cleans the edges of the electronic paper surface. After the electronic paper has undergone two cleaning processes, the carrying mechanism 8 drives the electronic paper to rotate around the axis of the rotating base 5 and returns to the initial position. The cleaned electronic paper can then be removed from the carrying mechanism 8 to facilitate the placement of the electronic paper to be cleaned on the carrying mechanism 8. The above cleaning process is repeated, and the electronic paper is continuously loaded, cleaned, cleaned, and unloaded. The fully automated setting greatly improves the cleaning efficiency of the electronic paper.

[0029] In addition, in order to realize automatic cleaning of both sides of the electronic paper, the carrying mechanism 8 has the function of clamping the electronic paper, and a gear 18 is installed on each shaft 7, a fixing frame 19 is provided on the support base 4, and an arc-shaped rack 20 is provided on the fixing frame 19 for driving the gear 18 to rotate. The gear 18 is driven by the arc-shaped rack 20 during the movement around the axis of the rotating base 5 so that the electronic paper is turned over after the second cleaning is completed; when the electronic paper on the carrying mechanism 8 completes the second cleaning and the lifting base 6 is controlled to reset upward, the rotating base 5 is controlled to rotate 90° on the support base 4, and the rotating shaft 7 carries the gear 18 around the rotating base 5. The axis of rotation of the seat 5 moves. During this movement, the gear 18 (the gear 18 corresponding to the electronic paper that has completed the second cleaning) and the arc-shaped rack 20 contact and mesh, which drives the gear 18 to rotate, so that the rotating shaft 7 drives the supporting mechanism 8 on the lifting seat 6 to rotate 180 degrees around its axis, achieving the effect of flipping the electronic paper. The supporting mechanism 8 is then controlled to release the electronic paper. At this time, the side of the electronic paper to be cleaned faces up and the cleaned side faces down. The rotating seat 5 is controlled to continue rotating on the support seat 4, so that the electronic paper undergoes two more cleaning processes, achieving automatic cleaning of both sides of the electronic paper. The lifting seat 6 is controlled to move up and down to facilitate the rotating seat 5 to drive the supporting mechanism 8 to rotate and prevent the supporting mechanism 8 from being blocked by other mechanisms.

[0030] Furthermore, the supporting mechanism 8 includes a support frame 81 installed at the end of the rotating shaft 7, and the support frame 81 is formed with a pair of vertically arranged guide grooves 82. A pair of supporting plates 85 are arranged up and down and can slide toward or away from each other at the guide grooves 82. The pair of supporting plates 85 are symmetrically arranged based on the axis of the rotating shaft 7; the supporting plates 85 are used to support the electronic paper. After the electronic paper is placed on the supporting plates 85 placed below, the lifting seat 6 is controlled to move up and down on the rotating seat 5 and the rotating seat 5 is controlled to rotate on the supporting seat 4, so that the electronic paper can be driven to move up and down and rotate around the axis of the rotating seat 5. After the electronic paper is driven to the designated cleaning position, the first cleaning and the second cleaning process are performed.

[0031] After the electronic paper has undergone the second cleaning process, it needs to be turned over. At this time, the pair of supporting plates 85 are controlled to slide towards each other to clamp the electronic paper. In the process of clamping and driving the supporting plates 85 to rotate around the axis of the rotating base 5, the arc-shaped rack 20 cooperates with the gear 18 to drive the rotating shaft 7 to rotate 180°, so that the clamped electronic paper is flipped 180°, thereby realizing the turning of the electronic paper.

[0032] In order to control a pair of slides toward or away from each other, a vertically arranged forward and reverse screw rod 83 is rotatably provided in each guide groove 82. Both ends of the forward and reverse screw rod 83 extend outward through the support frame 81. A first driven wheel 86 and a second driven wheel 87 are respectively mounted on the ends of the forward and reverse screw rods 83 extending outside the support frame 81 on the same side. A transmission belt 810 is wound around the first driven wheel 86 and the second driven wheel 87. A first servo motor 88 is also mounted on the support frame 81. The output shaft of the first servo motor 88 is mounted with a driving wheel 89 larger than the first driven wheel 86 and the second driven wheel 87. The transmission belt 810 is wound around the driving wheel 89. When the first servo motor 88 is operated, the driving wheel 89 is driven to rotate. Under the transmission action of the transmission belt 810, the first driven wheel 86 and the second driven wheel 87 can be driven to rotate synchronously, thereby controlling the forward and reverse screw rods 83 on both sides to rotate synchronously and controlling the pair of slides toward or away from each other.

[0033] Furthermore, a transport mechanism 9 is installed in the supporting shell 2 for placing the electronic paper to be cleaned on the carrying mechanism 8 or removing the cleaned electronic paper from the carrying mechanism 8, and a material inlet and outlet 3 is provided on the side of the supporting shell 2; by setting the material inlet and outlet 3, the transport mechanism 9 can transport the electronic paper, and the material inlet and outlet 3 is connected to the equipment for continuously feeding the electronic paper (not shown in the figure), and then cooperates with the transport mechanism 9 to continuously place the electronic paper to be cleaned on different carrying mechanisms 8, or transport the cleaned electronic paper out of the device from the material inlet and outlet 3.

[0034] A first cleaning table 10 is installed in the supporting shell 2 for supporting the lowered supporting plate 85. The top surface of the first cleaning table 10 is the first cleaning station, and a first placement groove 101 for positioning the supporting plate 85 is formed on the top surface of the first cleaning table 10. A middle surface wiping mechanism 12 is also installed next to the first cleaning table 10 and is used for performing the first cleaning of the electronic paper placed on the supporting plate 85, as well as a first adjustment mechanism 11 for controlling the upper and lower and lateral movements of the middle surface wiping mechanism 12. After the electronic paper to be cleaned is placed on the corresponding supporting plate 85 placed below by operating the transport mechanism 9, the rotating seat 5 is controlled to rotate 90° on the support seat 4, so that the supporting plate 85 can be driven to be placed directly above the first placement groove 101. Then the lifting seat 6 is controlled to move downward to drive the supporting plate 85 below to be placed in the first placement groove 101, so that the supporting plate 85 is supported by the first cleaning table 10 and positioned by the first placement groove 101, so that the electronic paper placed on the supporting plate 85 is placed in the first cleaning station, and finally the middle surface wiping mechanism 12 is operated to perform the first cleaning treatment on the electronic paper placed in the first cleaning station and clean the middle position of the surface of the electronic paper. After the cleaning is completed, the middle surface wiping mechanism 12 stops running and resets, and then the lifting seat 6 is controlled to move upward so that the rotating seat 5 can continue to drive the supporting plate 85 to rotate 90° around the axis line for the subsequent second cleaning treatment.

[0035] In addition, a first pressing mechanism 13 for pressing the edge position of the electronic paper to be cleaned is installed on the first cleaning table 10. A pair of first pressing mechanisms 13 are provided, and are respectively placed on both sides of the first placement groove 101; when the supporting plate 85 moves downward to be placed in the first placement groove 101, the first pressing mechanisms 13 on both sides are operated to clamp the two edges of the electronic paper at the designated first cleaning position, and when the middle position of the top surface of the electronic paper is wiped and cleaned by the middle surface wiping mechanism 12, the position of the electronic paper is prevented from shifting due to the action of friction, which affects the subsequent second cleaning and transportation of the electronic paper.

[0036] Furthermore, a second cleaning table 14 is installed in the supporting shell 2 for supporting the lowered supporting plate 85. The top surface of the second cleaning table 14 is a second cleaning station, and a second placement groove 141 for positioning the supporting plate 85 is formed on the top surface of the second cleaning table 14. There is also a surface edge wiping mechanism 16 placed next to the second cleaning table 14 and used for performing a second cleaning of the electronic paper placed on the supporting plate 85, as well as a second adjustment mechanism 15 for controlling the surface edge wiping mechanism 16 to move up and down and horizontally. After the electronic paper has undergone the first cleaning process, the rotating seat 5 drives the carrier plate 85 carrying the electronic paper that has been cleaned for the first time to be placed just above the second placement groove 141, and the lifting seat 6 is controlled to move downward again to drive the lower carrier plate 85 to be placed in the second placement groove 141, so that the carrier plate 85 is supported by the first cleaning table 10 and positioned by the first placement groove 101, so that the electronic paper placed on the carrier plate 85 is placed in the second cleaning station, and finally the surface edge wiping mechanism 16 is operated to perform a second cleaning process on the electronic paper placed in the second cleaning station, and the surface of the electronic paper is cleaned. The two sides are cleaned; after the electronic paper has undergone the second cleaning process, the lifting seat 6 is first controlled to reset upward, and then the upper and lower supporting plates 85 are controlled to move towards each other to clamp the electronic paper, and then the rotating seat 5 is controlled to rotate 90°. During the rotation process, the arc-shaped rack 20 cooperates with the gear 18 to drive the rotating shaft 7 to rotate 180°, so that the clamped electronic paper is flipped 180° to realize the turning over of the electronic paper. After turning over, the other side of the electronic paper is cleaned for the second time; the above cleaning process is repeated to realize orderly automatic cleaning of different electronic papers.

[0037] A second pressing mechanism 17 is installed on the second cleaning table 14 for pressing the middle position of the electronic paper to be cleaned. When the supporting plate 85 moves downward to be placed in the second placement groove 141, the second pressing mechanism 17 is operated to clamp the middle position of the electronic paper at the designated second cleaning position. The second pressing mechanism 17 has the same function as the first pressing mechanism 13, both of which are to prevent the position of the electronic paper from shifting due to friction during the cleaning process.

[0038] In this embodiment, in order to control the rotating base 5 to rotate a specified angle (i.e., 90°) on the support base 4, an axially vertically arranged rotating column 21 is provided in the support base 4. The top of the rotating column 21 is fixed to the rotating base 5, and the bottom of the rotating base 5 extends below the support shell 2 and is equipped with a driven tooth 22 at its bottom end. The base 1 is equipped with a fifth servo motor 23, and the output shaft of the fifth servo motor 23 is equipped with a driving tooth 24 that meshes with the driven tooth 22. When the fifth servo motor 23 is operated, the driving tooth 24 and the driven tooth 22 drive the rotating column 21 to rotate, thereby driving the rotating base 5 to rotate a specified angle on the support base 4. In addition, the number of teeth of the driving tooth 24 is smaller than the number of teeth of the driven tooth 22. Under the effect of the transmission ratio, the rotation speed of the rotating base 5 is reduced and the output torque is increased, thereby improving the accuracy of driving the rotating base 5 to rotate the specified angle and preventing errors.

[0039] To enable the lifting seats 6 to move up and down on the side of the rotating base 5, the rotating base 5 is formed with lifting slots 27, the same number as the lifting seats 6. These slots 27 are arranged in a row, equidistantly around the axis of rotation of the rotating base 5. There are four lifting slots 27, each of which is fitted with a vertically arranged second guide rod 28. The lifting seats 6 slide up and down on different second guide rods 28, and each second guide rod 28 is fitted with a spring 29 for applying a downward force to the lifting seats 6. Applying a downward force to the lifting seats 6 causes them to move downward on the second guide rods 28. The springs 29 compress, and when the force on the lifting seats 6 ceases, the lifting seats 6 automatically return to their upward position under the action of the compressed springs 29.

[0040] When the rotating base 5 is controlled to rotate on the support base 4 and no downward thrust is applied to the lifting base 6, to prevent the lifting base 6 from automatically moving up and down on the rotating base 5, an L-shaped limiting rod 25 is provided on each lifting base 6. An annular limiting groove 26 is formed on the side of the support base 4. The bottom end of the limiting rod 25 slides within the limiting groove 26. When the rotating base 5 drives the plurality of lifting bases 6 to rotate about its axis, the bottom end of the limiting rod 25 slides within the limiting groove 26. Under the limiting action of the limiting groove 26, the lifting base 6 is prevented from automatically moving up and down on the rotating base 5.

[0041] However, to allow the lifting base 6 to move up and down at a designated position, the side of the support base 4 is further formed with a clearance groove 30 that allows the bottom end of the limiting rod 25 to move up and down. A pair of clearance grooves 30 are provided, one aligned with the first cleaning station 10 and the other aligned with the second cleaning station 14. When the rotating base 5 drives the supporting plate 85 to be placed directly above the first cleaning station 10, the limiting rod 25 corresponding to the supporting plate 85 aligns with the clearance groove 30 (the clearance groove 30 corresponding to the first cleaning station 10). Under the action of the clearance groove 30, the lifting base 6 can move up and down without being restricted by the limiting slide groove 26. When the rotating base 5 drives the supporting plate 85 to be placed directly above the second cleaning station 14, the limiting rod 25 corresponding to the supporting plate 85 aligns with the next clearance groove 30 (the clearance groove 30 corresponding to the second cleaning station 14).

[0042] A pair of second electric push rods 31 are installed in the support seat 4, which are respectively placed above different give way slots 30 and are used to push the limit rod 25 to move downward. When the carrier plate 85 carrying the electronic paper that has undergone the first cleaning process is aligned with the second placement slot 141 on the second cleaning table 14, the carrier plate 85 carrying the electronic paper to be cleaned is aligned with the first placement slot 101 on the first cleaning table 10, and the pair of second electric push rods 31 are running at the same time. The telescopic rods of the second electric push rods 31 extend downward, thereby contacting the bottom end of the L-shaped limit rod 25, thereby applying a downward thrust to the limit rod 25, and the limit rod 25 moves downward into the give way slot 30 to drive the lifting seat 6 to move upward, so that the carrier plate 85 carrying the electronic paper that has undergone the first cleaning process moves downward into the second placement slot 141, and the carrier plate 85 carrying the electronic paper to be cleaned moves downward into the first placement slot 101.

[0043] Additionally, a positioning mechanism 32 is installed on the lifting base 6 for accurately positioning the rotating shaft 7 when it rotates a specified angle (i.e., 180°). After the rotating shaft 7 is driven to rotate 180° under the cooperation of the arc-shaped rack 20 and the gear 18, it is accurately positioned by the positioning mechanism 32 to prevent the rotating shaft 7 from rotating beyond 180° due to inertia. Figure 5 As shown, the positioning mechanism 32 includes a mounting housing 321 mounted on the lifting base 6. A rotating member 322 is mounted on the rotating shaft 7 and is positioned within the mounting housing 321. The rotating member 322 is in the shape of a circular pancake and has a pair of oppositely disposed positioning slots 323 formed on its outer circumference. A first positioning spring 324 is mounted within the mounting housing 321 for engaging with one of the positioning slots 323, and a second positioning spring 325 is mounted for engaging with the other positioning slot 323. The oppositely disposed pair of positioning slots 323 are symmetrically arranged and form an angle of 180°. When the rotating shaft 7 is driven to rotate 180°, the pair of positioning slots 323 on the rotating member 322 remain engaged by the first positioning spring 324 and the second positioning spring 325, thereby achieving positioning of the rotating shaft 7.

[0044] like Figure 6 As shown, the transport mechanism 9 includes a support frame 91 and a first guide rod 92 laterally arranged on the support frame 91, and a movable seat 93 that can slide toward or away from the supporting plate 85 is slidably provided on the first guide rod 92, and a lifting member 94 that can move up and down is provided on the movable seat 93, and a vacuum suction plate 95 for sucking electronic paper is installed on the lifting member 94; when the supporting plate 85 is rotated to align with the vacuum suction plate 95, the supporting plates 85 are in an open state away from each other, and then the movable seat 93 is controlled to slide on the first guide rod 92 toward the supporting plate 85, so as to drive the vacuum suction plate 95 with the electronic paper to be placed between the two supporting plates 85, and then the lifting member 94 is controlled to move downward to place the electronic paper on the supporting plate 85 below, thereby realizing new transportation of the electronic paper. In addition, when the electronic paper that has been cleaned is aligned with the vacuum suction plate 95, the movable seat 93 drives the vacuum suction plate 95 to be placed between the two supporting plates 85, and controls the lifting member 94 to move downward so that the vacuum suction plate 95 contacts the cleaned electronic paper. The vacuum suction plate 95 is operated to suck the electronic paper, and then the lifting member 94 is controlled to reset upward. The movable seat 93 drives the vacuum suction plate 95 to move in a direction away from the supporting plate 85, thereby transporting the cleaned electronic paper and transporting it out of the device.

[0045] In order to control the movable seat 93 to automatically slide on the first guide rod 92, a first screw rod 96 is rotatably provided on the support frame 91, the length direction of which is parallel to the length direction of the first guide rod 92. The first screw rod 96 is threadedly connected to the movable seat 93. The support frame 91 is also equipped with a second servo motor 97, and the output shaft of the second servo motor 97 is connected to one end of the first screw rod 96 through a first transmission component 98. The first transmission component 98 can be a transmission structure composed of a pulley and a belt. When the second servo motor 97 is operated, the first screw rod 96 is driven to rotate under the transmission action of the first transmission component 98, thereby controlling the movable seat 93 to automatically slide on the first guide rod 92.

[0046] like Figure 7-9As shown, the first adjustment mechanism 11 includes a laterally arranged support rail 111, on which is provided a movable plate 113 that can slide laterally toward or away from the rotating seat 5, and on the movable plate 113, a lifting plate 116 that can slide up and down and a plurality of cylinders 117 with vertically arranged telescopic rods, the ends of the telescopic rods of the cylinders 117 are fixed to the lifting plate 116, and the middle surface wiping mechanism 12 is arranged on the lifting plate 116; by operating the cylinders 117, the lifting plate 116 can be controlled to move up and down on the movable plate 113 to adjust the height of the middle surface wiping mechanism 12, and then the movable plate 113 can be controlled to slide laterally on the support rail 111, so as to drive the middle surface wiping mechanism 12 to contact the electronic paper placed on the first cleaning table 10, so as to facilitate the first cleaning process thereof.

[0047] However, in order to control the lateral sliding of the movable plate 113 on the support rail 111, a second screw rod 112 arranged transversely is rotatably mounted on the support rail 111. The movable plate 113 is threadably connected to the second screw rod 112. The support rail 111 is also equipped with a third servo motor 114. The output shaft of the third servo motor 114 is in transmission connection with one end of the second screw rod 112 via a second transmission component 115. The second transmission component 115 can be two mutually meshing transmission teeth. When the third servo motor 114 is operated, the second screw rod 112 is driven to rotate under the transmission action of the second transmission component 115, thereby controlling the lateral sliding of the movable plate 113 on the support rail 111.

[0048] Furthermore, the middle surface wiping mechanism 12 includes a first cleaning cloth belt 129 for wiping and cleaning the middle position of the surface of the electronic paper, and also includes an I-shaped feeding wheel 121 rotatably set on the lifting plate 116 and used for continuously feeding out the first cleaning cloth belt 129 and an I-shaped feeding wheel 122 for continuously feeding in the first cleaning cloth belt 129. A first bracket 126 is installed below the lifting plate 116, and a pair of first upper guide rollers 127 and a pair of first lower guide rollers 128 are rotatably provided on the first bracket 126. The pair of first upper guide rollers 127 and the pair of first lower guide rollers 128 are arranged up and down, and the pair of first lower guide rollers 128 are at the same height. The fed first cleaning cloth belt 129 is sequentially wound around the first lower guide roller 128 and the first lower guide roller 128 to stretch the first cleaning cloth belt 129, so that the first cleaning cloth belt 129 wound around the first lower guide roller 128 is arranged flatly, so as to fully contact the middle position of the surface of the electronic paper.

[0049] Specifically, under the coordination of controlling the up and down movement of the lifting plate 116 and the lateral movement of the movable plate 113, the first cleaning cloth belt 129 wound on the first lower guide roller 128 is driven to contact the middle position of the electronic paper surface placed on the first cleaning table 10. After contact, the I-shaped unloading wheel 121 and the I-shaped receiving wheel 122 are driven to rotate synchronously in the same direction, so that the first cleaning cloth belt 129 is moved to wipe and clean the middle position of the electronic paper surface; and, while the first cleaning cloth belt 129 is moved for cleaning, the movable plate 113 can also be controlled to move on the support rail 111 in a direction away from the first cleaning table 10, thereby increasing the wiping area of ​​the first cleaning cloth belt 129 and the cleaning effect.

[0050] Secondly, the lifting plate 116 is equipped with a pair of first driving mechanisms 123 that respectively drive the I-shaped unloading wheel 121 and the I-shaped receiving wheel 122 to rotate, and the I-shaped unloading wheel 121 and the I-shaped receiving wheel 122 are detachably mounted on different first driving mechanisms 123; by running a pair of first driving mechanisms 123 at the same time, the I-shaped unloading wheel 121 and the I-shaped receiving wheel 122 can be driven to rotate synchronously in the same direction to realize the unloading and receiving of the first cleaning cloth belt 129. In addition, the first driving mechanism 123 can also automatically loosen the I-shaped unloading wheel 121 and the I-shaped receiving wheel 122, so that the two can be disassembled for replacement and replaced with a new first cleaning cloth belt 129 roll.

[0051] In order to improve the cleaning efficiency of the first cleaning cloth belt 129, a supporting cross bar 1210 is provided on the first bracket 126, and a movable frame 1211 that can move up and down is installed on the supporting cross bar 1210. A plurality of pressure rollers 1212 whose length direction is consistent with the length direction of the first lower guide roller 128 are rotatably provided on the movable frame 1211. The pressure rollers 1212 are placed above the first cleaning cloth belt 129 wound on the first lower guide roller 128 to apply downward pressure to the first cleaning cloth belt 129. After the bottom surface of the first cleaning cloth belt 129 wound on the first lower guide roller 128 contacts the middle position of the electronic paper surface placed on the first cleaning table 10, the movable frame 1211 is controlled to move downward on the supporting cross bar 1210, and the multiple pressure rollers 1212 are at the same height. The multiple pressure rollers 1212 apply downward pressure to the first cleaning cloth belt 129 wound on the first lower guide roller 128, so that the bottom surface of the first cleaning cloth belt 129 is in full contact with the middle position of the electronic paper surface, further improving the wiping force and cleaning efficiency of the first cleaning cloth belt 129.

[0052] Additionally, the support crossbar 1210 is equipped with a plurality of vertically arranged first electric push rods 1213, each of which has a telescopic rod end fixed to the movable frame 1211. When the plurality of first electric push rods 1213 are operated simultaneously, the telescopic rods extend and retract to drive the movable frame 1211 to automatically move up and down on the support crossbar 1210.

[0053] Furthermore, the first driving mechanism 123 includes a first guide rail 1231 and a second guide rail 1235 which are installed on the lifting plate 116 and arranged in a mirror image.

After controlling the first sliding seat 1232 and the second sliding seat 1236 to slide in the direction away from each other, the I-shaped unwinding wheel 121 or the I-shaped receiving wheel 122 can be placed between the first turntable 1234 and the second turntable 1238, and the I-shaped unwinding wheel 121 or the I-shaped receiving wheel 122, the first turntable 1234 and the second turntable 1238 are coaxially arranged, and then the first sliding seat 1232 and the second sliding seat 1236 are controlled to slide in the direction close to each other, through the first turntable 1234 and the second The turntable 1238 clamps the I-shaped discharge wheel 121 or the I-shaped receiving wheel 122, and the I-shaped discharge wheel 121 or the I-shaped receiving wheel 122 is newly installed. When the two need to be disassembled, the first sliding seat 1232 and the second sliding seat 1236 are controlled to slide away from each other again; and then the first drive motor 1233 and the second drive motor 1237 are operated at the same time to drive the I-shaped discharge wheel 121 or the I-shaped receiving wheel 122 to rotate, thereby discharging or receiving the first cleaning cloth belt 129.

[0054] Additionally, a plurality of inlay grooves 125 are formed at both ends of the I-shaped discharge wheel 121 and the I-shaped receiving wheel 122. A plurality of inlay blocks 124 are provided on the side of the first rotary disc 1234 and the second rotary disc 1238 that are adjacent to each other, and are capable of being inserted into the inlay grooves 125. When the first sliding seat 1232 and the second sliding seat 1236 are controlled to move toward each other, the I-shaped discharge wheel 121 or the I-shaped receiving wheel 122 is clamped by the first rotary disc 1234 and the second rotary disc 1238, and the plurality of inlay blocks 124 are respectively inserted into different inlay grooves 125. This not only improves installation accuracy but also prevents deviation during the rotation of the I-shaped discharge wheel 121 and the I-shaped receiving wheel 122.

[0055] like Figure 10As shown, the first pressing mechanism 13 includes a protective shell 131 provided on the first cleaning table 10, and a fourth servo motor 132 is installed in the protective shell 131. The fourth servo motor 132 is arranged in a lying position. The first pressing mechanism 133 also includes a swing rod 133. One end of the swing rod 133 is fixed to the output shaft of the fourth servo motor 132, and the other end is provided with a first pressing rod 134 for pressing the edge of the electronic paper placed at the first cleaning station. The first pressing rod 134 is placed at a position deviating from the position directly above the first placement slot 101; the lifting seat 6 is controlled to move downward to drive the carrying plate 85 downward. The electronic paper is moved and embedded into the first placement groove 101. At this time, the electronic paper placed on the carrier plate 85 is placed at the first cleaning station. The fourth servo motor 132 is then operated to drive the pendulum 133 to swing around the axis of the output shaft of the fourth servo motor 132. The pendulum 133 drives the first pressure rod 134 to move until it contacts the edge of the electronic paper to press it. During the subsequent wiping and cleaning process with the first cleaning cloth 129, the position of the electronic paper will not shift, which facilitates the subsequent second cleaning process and improves the cleaning efficiency. In addition, an arc-shaped guide rod 135 is also installed in the protective shell 131 for guiding the pendulum 133. The pendulum 133 is slidably set on the arc-shaped guide rod 135; the arc trajectory of the arc-shaped guide rod 135 itself is consistent with the trajectory of the pendulum 133. Under the action of the arc-shaped guide rod 135, it can be more stable when driving the pendulum 133 to swing.
