Description

Technical Field

[0001] This disclosure relates to the field of solar cell manufacturing technology, and in particular to a screen wiping tool. Background Technology

[0002] Screen printing is a crucial step in the solar cell manufacturing process and is currently the most widely used printing technology in crystalline silicon cell fabrication. It significantly impacts photoelectric conversion efficiency and product yield. A high percentage of defective products in screen printing are caused by broken lines or incomplete printing, typically due to ink clogging the mesh. Therefore, wiping the screen is necessary to clear the blockage. However, existing screen wiping methods often damage the screen and are ineffective at cleaning. Utility Model Content

[0003] This disclosure provides a screen wiping tool to solve the problems of existing screen wiping methods that easily cause screen damage and have poor cleaning effect.

[0004] According to some embodiments of this disclosure, one aspect of this disclosure provides a screen wiping tool, including:

[0005] The housing has a first rotating shaft and a second rotating shaft that are parallel and rotatable inside, and a first through hole and a second through hole that are parallel and spaced apart on the housing.

[0006] The wiping cloth has one end wound around the first rotating shaft, and the other end of the wiping cloth passes through the first perforation to the outside of the housing, then through the second perforation into the housing and is wound around the second rotating shaft. The portion of the wiping cloth outside the housing is in contact with the outer wall of the housing to form the wiping area of ​​the screen wiping tool.

[0007] In some embodiments, both the first perforation and the second perforation are arranged to extend axially along the first axis of rotation.

[0008] In some embodiments, the distance between the first rotating shaft and the first perforation is greater than the distance between the second rotating shaft and the second perforation, so that at least a portion of the wiping area is inclined relative to the plane in which the central axes of the first rotating shaft and the second rotating shaft are located.

[0009] In some embodiments, the housing includes a first shell wall, a second shell wall, and a third shell wall. The first shell wall and the second shell wall are respectively close to the first rotating shaft and the second rotating shaft in the direction of the interval between the first rotating shaft and the second rotating shaft. The two ends of the third shell wall are respectively connected to the ends of the first shell wall and the second shell wall away from the first rotating shaft.

[0010] The first perforation is located on the first shell wall or on the third shell wall at the end near the first shell wall;

[0011] The second perforation is provided at one end of the second shell wall or the third shell wall near the second shell wall.

[0012] In some embodiments, the first perforation is disposed at one end of the first shell wall near the third shell wall, and the wiping area covers the connection between the first shell wall and the third shell wall.

[0013] In some embodiments, the second perforation is disposed at one end of the second shell wall near the third shell wall, and the wiping area covers the connection between the second shell wall and the third shell wall.

[0014] In some embodiments, the third shell wall is gradually inclined toward the first rotating shaft from one end near the first rotating shaft to one end near the second rotating shaft.

[0015] In some embodiments, the screen wiping tool further includes a synchronous transmission mechanism, which connects the first rotating shaft and the second rotating shaft at the same end along the axial direction of the first rotating shaft, so as to drive the first rotating shaft and the second rotating shaft to rotate synchronously through the synchronous transmission mechanism.

[0016] In some embodiments, the synchronous transmission mechanism includes:

[0017] The first transmission wheel is disposed on the first rotating shaft;

[0018] The second transmission wheel is mounted on the second rotating shaft and is connected to the first transmission wheel via a transmission belt.

[0019] In some embodiments, one end of the first rotating shaft extends out of the housing to form an operating part, so as to rotate the first rotating shaft through the operating part.

[0020] In some embodiments, the operating part is provided with a knob.

[0021] The technical solutions provided in this disclosure have at least the following advantages:

[0022] In the screen wiping tool provided in this embodiment, after the wiping cloth is installed on the housing, both ends of the wiping cloth are wound around the first and second rotating shafts respectively. Part of the wiping cloth is located outside the housing and between the first and second perforations. The part of the wiping cloth outside the housing forms a wiping area for wiping the screen. The wiping area can fit against the outer wall of the housing. In this way, the wiping area of ​​the wiping cloth can wipe the screen evenly, so that the area of ​​the screen in contact with the wiping cloth is evenly stressed, which improves the wiping effect of the screen wiping tool and makes it less likely to cause damage to the screen, thus improving the life of the screen and the printing quality. At the same time, after the wiping area of ​​the wiping cloth is used, the used wiping area can be moved by rotating the first and second rotating shafts, thereby ensuring that the wiping area of ​​the wiping cloth is clean when wiping the screen next time. Attached Figure Description

[0023] One or more embodiments are illustrated by way of example with corresponding pictures in the accompanying drawings. These illustrations do not constitute a limitation on the embodiments. Unless otherwise stated, the pictures in the accompanying drawings do not constitute a limitation on scale. In order to more clearly illustrate the technical solutions in the embodiments of this disclosure or the conventional technology, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1 This is one of the structural schematic diagrams of a screen wiping tool provided in an embodiment of the present disclosure;

[0025] Figure 2 This is a second schematic diagram of the structure of a screen wiping tool provided in an embodiment of the present disclosure. Detailed Implementation

[0026] As can be seen from the background technology, there are three existing methods for wiping screens: one is to wipe the screen with a lint-free cloth. When the screen needs wiping, the lint-free cloth is folded into a small square by hand and wiped in the same direction under the screen. The lint-free cloth is supported by the fingers while wiping the screen. Because the fingers are not at the same level, it will result in uneven force and the wiped area will not be completely covered after one wipe (the gaps between the fingers cannot be wiped because the lint-free cloth is not under pressure). The other method is to wipe the screen with a soft brush. When the screen needs wiping, a soft brush is used to wipe in the same direction under the screen. When wiping the screen, soft brushes can cause significant damage to the screen's adhesive film, easily leading to screen breakage and affecting its lifespan. Another method is to use a nano sponge. When the screen needs wiping, use the nano sponge to wipe it from below in the same direction. However, because the sponge is relatively soft, it is not very effective at cleaning when local printing areas are clogged with ink, resulting in poor printing. It cannot effectively clean the screen, and small foreign objects stuck to the sponge are not easy to remove. If not noticed in time, continuing to wipe the screen can easily puncture it, affecting its lifespan.

[0027] This disclosure provides a screen wiping tool. After the wiping cloth is installed on the housing, both ends of the wiping cloth are wound around a first rotating shaft and a second rotating shaft, respectively. A portion of the wiping cloth is located outside the housing and between a first perforation and a second perforation. The portion of the wiping cloth outside the housing forms a wiping area for wiping the screen. The wiping area can fit against the outer wall of the housing, so that the wiping area of ​​the wiping cloth can be used to wipe the screen evenly, so that the area of ​​the screen in contact with the wiping cloth is subjected to uniform force, improving the wiping effect of the screen wiping tool and reducing the risk of damage to the screen, thus improving the lifespan and printing quality of the screen. At the same time, after the wiping area of ​​the wiping cloth is used, the used wiping area can be moved by rotating the first rotating shaft and the second rotating shaft, thereby ensuring that the wiping area of ​​the wiping cloth is clean when wiping the screen next time.

[0036] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0037] This disclosure provides a screen wiping tool that can be used to wipe screens. Figures 1 to 2 A preferred embodiment of the screen wiping tool provided in this disclosure is shown.

[0038] Please see Figures 1 to 2The screen wiping tool 100 includes a housing 1, a first rotating shaft 2, a second rotating shaft 3, and a wiping cloth 4. The housing 1 has a parallel and rotatable first rotating shaft 2 and second rotating shaft 3. The housing 1 has a parallel and spaced first through hole 11 and a second through hole 12. One end of the wiping cloth 4 is wound around the first rotating shaft 2, and the other end of the wiping cloth 4 passes through the first through hole 11 to the outside of the housing 1, and then passes through the second through hole 12 into the housing 1 and is wound around the second rotating shaft 3. The part of the wiping cloth 4 located outside the housing 1 is in contact with the outer wall of the housing 1 to form the wiping area 41 of the screen wiping tool 100.

[0039] Specifically, the housing 1 has a hollow structure, forming an internal cavity to accommodate the first rotating shaft 2, the second rotating shaft 3, and the wiping cloth 4. The central axis of the first rotating shaft 2 is parallel or approximately parallel to the central axis of the second rotating shaft 3, allowing them to be arranged parallel to each other within the housing 1. Both the first rotating shaft 2 and the second rotating shaft 3 are rotatable relative to the housing 1 along the axial direction of the first rotating shaft 2, and are spaced apart radially from the first rotating shaft 2. Hereinafter, the axial direction of the first rotating shaft 2 is defined as left-right, and the spacing between the first rotating shaft 2 and the second rotating shaft 3 is defined as front-back, with the first rotating shaft 2 located behind the second rotating shaft 3.

[0040] The wiping cloth 4 can be a cleanroom cloth, etc. The following description will use a cleanroom cloth as an example. The wiping cloth 4 is a cylindrical cleanroom cloth, wound into a cylindrical shape. The wiping cloth 4 has a first end and a second end opposite to each other in the winding direction. The first end of the wiping cloth 4 is closer to the central axis of the wiping cloth 4 than the second end. When the wiping cloth 4 is installed on the housing 1, it can be fitted onto the first rotating shaft 2; it can also be fitted onto the second rotating shaft 3. The following description will use the example of the wiping cloth 4 being fitted onto the first rotating shaft 2.

[0041] When the wiping cloth 4 is installed on the housing 1, firstly, the wiping cloth 4 is sleeved on the first rotating shaft 2 so that the first end of the wiping cloth 4 is wound around the first rotating shaft 2 circumferentially; then, the second end of the wiping cloth 4 is passed out from the first perforation 11 to the outside of the housing 1, and then the second end of the wiping cloth 4 is passed into the housing 1 from the second perforation 12; finally, the second end of the wiping cloth 4 that has passed into the housing 1 from the second perforation 12 is fixedly wound around the second rotating shaft 3, and the wiping cloth 4 is pulled taut so that the part of the wiping cloth 4 outside the housing 1 can fit against the outer wall of the housing 1 between the first perforation 11 and the second perforation 12. In this way, the wiping cloth 4 is installed on the housing 1, and the part of the wiping cloth 4 outside the housing 1 (that is, the part of the wiping cloth 4 between the first perforation 11 and the second perforation 12) forms the wiping area 41, through which the operator can wipe the screen.

[0042] During the process of the operator wiping the screen with the screen wiping tool 100, if the cleanliness of the wiping area 41 of the wiping cloth 4 no longer meets the wiping requirements after wiping the screen, the used wiping area 41 (i.e., the used part of the wiping cloth 4) can be allowed to enter the housing 1 through the second perforation 12 by rotating the first rotating shaft 2 and gradually be wound onto the second rotating shaft 3. While the used part of the wiping cloth 4 moves into the housing 1, the unused part of the wiping cloth 4 wound on the first rotating shaft 2 will gradually unfold and move out of the housing 1 from the first perforation 11, thus forming a new wiping area 41. This process continues until the entire wiping cloth 4 has been used, at which point a new wiping cloth 4 can be replaced and reused. The housing 1 is typically composed of two sub-housings connected by snap-fit ​​or screw connections, making it easy to disassemble and replace the wiping cloth 4.

[0043] After the wiping cloth 4 is installed on the housing 1, both ends of the wiping cloth 4 are wound around the first rotating shaft 2 and the second rotating shaft 3 respectively. Part of the wiping cloth 4 is located outside the housing 1 and between the first through hole 11 and the second through hole 12. The part of the wiping cloth 4 outside the housing 1 forms a wiping area 41 for wiping the screen. The wiping area 41 can fit against the outer wall of the housing 1. In this way, the wiping area 41 of the wiping cloth 4 can wipe the screen evenly, so that the area of ​​the screen in contact with the wiping cloth 4 is evenly stressed, which improves the wiping effect of the screen wiping tool 100 on the screen and is less likely to cause damage to the screen, thus improving the life of the screen and the printing quality. At the same time, after the wiping area 41 of the wiping cloth 4 is used, the used wiping area 41 can be moved by rotating the first rotating shaft 2 and the second rotating shaft 3, thereby ensuring that the wiping area 41 of the wiping cloth 4 is clean when wiping the screen next time.

[0044] The embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0045] Both the first through hole 11 and the second through hole 12 are elongated holes. The extending direction of the first through hole 11 is parallel or approximately parallel to the extending direction of the second through hole 12, so that the first through hole 11 and the second through hole 12 can be arranged in parallel on the housing 1. The extending direction of the first through hole 11 can be parallel or approximately parallel to the axial direction of the first rotating shaft 2; the extending direction of the first through hole 11 can also be at a certain angle to the axial direction of the first rotating shaft 2.

[0046] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the first perforation 11 and the second perforation 12 are both arranged to extend axially along the first rotating shaft 2.

[0047] Specifically, the extension directions of the first perforation 11 and the second perforation 12 are both parallel to the axial direction of the first rotating shaft 2. This helps to prevent the part of the wiping cloth 4 located between the first perforation 11 and the first rotating shaft 2, and the part located between the second perforation 12 and the second rotating shaft 3, from curling up.

[0048] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the first perforation 11 and the first rotating shaft 2 are arranged opposite each other in the radial direction of the first rotating shaft 2, and the second perforation 12 and the second rotating shaft 3 are arranged opposite each other in the radial direction of the second rotating shaft 3. This also helps to prevent the portion of the wiping cloth 4 between the first perforation 11 and the first rotating shaft 2, and the portion between the second perforation 12 and the second rotating shaft 3 from curling up.

[0049] The first perforation 11 and the second perforation 12 are spaced apart in a direction perpendicular to the extending direction of the first perforation 11. For example, the first perforation 11 and the second perforation 12 may be spaced apart horizontally and / or vertically. Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the distance between the first rotating shaft 2 and the first perforation 11 is greater than the distance between the second rotating shaft 3 and the second perforation 12, so that at least a portion of the wiping area 41 is inclined relative to the plane in which the central axes of the first rotating shaft 2 and the second rotating shaft 3 are located.

[0050] Specifically, the central axes of the first rotating shaft 2 and the second rotating shaft 3 are both parallel to the horizontal plane, so the planes on which the central axes of the first rotating shaft 2 and the second rotating shaft 3 lie are parallel to the horizontal plane. The vertical distance between the first perforation 11 and the first rotating shaft 2 is greater than the vertical distance between the second perforation 12 and the second rotating shaft 3, that is, the first perforation 11 is located above the second perforation 12, so that the end of the wiping area 41 near the first perforation 11 is located above the end of the wiping area 41 near the second perforation 12, thereby making at least a portion of the wiping area 41 inclined relative to the horizontal plane. This inclined arrangement of the wiping area 41 helps to increase the area of ​​the wiping area 41, thereby improving the wiping efficiency of the screen wiping tool 100, and making the way the operator holds and operates the screen wiping tool 100 more ergonomic.

[0051] The specific shape and style of the casing 1 can be set according to the actual situation. Optionally, please refer to Figure 1 and Figure 2In some embodiments, the housing 1 includes a first housing wall 13, a second housing wall 14, and a third housing wall 15. The first housing wall 13 and the second housing wall 14 are respectively close to the first rotating shaft 2 and the second rotating shaft 3 in the interval direction between the first rotating shaft 2 and the second rotating shaft 3. The two ends of the third housing wall 15 are respectively connected to the ends of the first housing wall 13 and the second housing wall 14 away from the first rotating shaft 2. The first through hole 11 is provided at the end of the first housing wall 13 or the third housing wall 15 close to the first housing wall 13. The second through hole 12 is provided at the end of the second housing wall 14 or the third housing wall 15 close to the second housing wall 14.

[0052] Specifically, the third shell wall 15 can be located above or below the first rotating shaft 2. The following description will use the example of the third shell wall 15 being located above the first rotating shaft 2 as an example. The third shell wall 15 is the upper shell wall of the housing 1. The first shell wall 13 is the rear shell wall of the housing 1, and the second shell wall 14 is the front shell wall of the housing 1. The first perforation 11 is located at the upper end of the first shell wall 13 or at the rear end of the third shell wall 15, and the second perforation 12 is located at the upper end of the second shell wall 14 or at the front end of the third shell wall 15. This ensures that at least a portion of the wiping area 41 of the wiping cloth 4 adheres to the third shell wall 15, making the wiping area 41 of the wiping cloth 4 smooth and flat.

[0053] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the first perforation 11 is provided at one end of the first shell wall 13 near the third shell wall 15, and the wiping area 41 covers the connection between the first shell wall 13 and the third shell wall 15.

[0054] Specifically, the first perforation 11 is located at the upper end of the first shell wall 13, allowing the wiping area 41 to be divided into a first wiping area and a second wiping area. The first wiping area of ​​the wiping cloth 4 is attached to the third shell wall 15. The first wiping area is smooth and flat, allowing for large-area and rapid wiping of the screen. The second wiping area of ​​the wiping cloth 4 is attached to the junction of the first shell wall 13 and the third shell wall 15. The second wiping area is linear or narrow strip-shaped, providing better wiping effect for difficult-to-clean abnormal areas on the screen.

[0055] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the second perforation 12 is located at one end of the second shell wall 14 near the third shell wall 15, and the wiping area 41 covers the connection between the second shell wall 14 and the third shell wall 15. Thus, the wiping cloth 4 also forms a second wiping area at the connection between the second shell wall 14 and the third shell wall 15, giving the screen wiping tool 100 two second wiping areas with different included angles. This enriches the operation methods of the screen wiping tool 100, making it easier for the operator to wipe difficult-to-handle abnormal areas on the screen using the second wiping area of ​​the wiping cloth 4.

[0056] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, the third shell wall 15 is gradually inclined toward the first rotating shaft 2 from one end near the first rotating shaft 2 to one end near the second rotating shaft 3.

[0057] Specifically, the third shell wall 15 is inclined downwards from back to front, which makes the first wiping area of ​​the wiping cloth 4 inclined, which helps to increase the area of ​​the wiping area 41, thereby improving the wiping efficiency of the screen wiping tool 100, and making the way the operator holds and operates the screen wiping tool 100 more ergonomic.

[0058] As described above, the used wiping area 41 can be moved by rotating the first rotating shaft 2 and the second rotating shaft 3. Optionally, please refer to... Figure 1 and Figure 2 In some embodiments, the screen wiping tool 100 further includes a synchronous transmission mechanism 5, which connects the first rotating shaft 2 and the second rotating shaft 3 to the same end in the axial direction of the first rotating shaft 2, so as to drive the first rotating shaft 2 and the second rotating shaft 3 to rotate synchronously through the synchronous transmission mechanism 5.

[0059] Specifically, a synchronous transmission mechanism 5 is provided between the first rotating shaft 2 and the second rotating shaft 3, located within the housing 1. This mechanism ensures that the first rotating shaft 2 and the second rotating shaft 3 rotate synchronously. The synchronous transmission mechanism 5 can connect the left end of the first rotating shaft 2 to the left end of the second rotating shaft 3; it can also connect the right end of the first rotating shaft 2 to the right end of the second rotating shaft 3. The following description will use the example of the synchronous transmission mechanism 5 connecting the left end of the first rotating shaft 2 to the left end of the second rotating shaft 3.

[0060] The specific configuration of the synchronous transmission mechanism 5 can be set according to actual conditions. The synchronous transmission mechanism 5 can be a gear transmission mechanism, a sprocket transmission mechanism, or a belt transmission mechanism, etc. Optionally, please refer to... Figure 1 and Figure 2 In some embodiments, the synchronous transmission mechanism 5 includes a first transmission wheel 51, a second transmission wheel 52, and a transmission belt 53. The first transmission wheel 51 is disposed on the first rotating shaft 2; the second transmission wheel 52 is disposed on the second rotating shaft 3, and the second transmission wheel 52 and the first transmission wheel 51 are connected by the transmission belt 53.

[0061] Specifically, the first transmission wheel 51 and the second transmission wheel 52 are respectively located at the left end of the first rotating shaft 2 and the left end of the second rotating shaft 3, and the first transmission wheel 51 and the second transmission wheel 52 are connected by a transmission belt 53. Thus, the synchronous transmission mechanism 5 is set as a belt drive mechanism, and this setting method of the synchronous transmission mechanism 5 is relatively simple.

[0062] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, one end of the first rotating shaft 2 extends out of the housing 1 to form an operating part 21, so as to rotate the first rotating shaft 2 through the operating part 21.

[0063] Specifically, the operating part 21 can be formed by the left or right end of the first rotating shaft 2 extending out of the housing 1; the operating part 21 can also be formed by the left or right end of the second rotating shaft 3 extending out of the housing 1. Thus, the operating part 21 is usually provided at the end of the first rotating shaft 2 away from the synchronous transmission mechanism 5, so that the operator can synchronously rotate the first rotating shaft 2 and the second rotating shaft 3 through the operating part 21.

[0064] Further, please refer to Figure 1 and Figure 2 In some embodiments, a knob 22 is provided on the operating part 21. By providing a knob 22 on the operating part 21, the operator can more easily and conveniently rotate the first rotating shaft 2 and the second rotating shaft 3 simultaneously by using the knob 22.

[0065] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, two first limiting rings 23 are provided on the first rotating shaft 2, and the two first limiting rings 23 abut against the two sides of the wiping cloth 4 in the axial direction of the first rotating shaft 2.

[0066] Specifically, two first limiting rings 23 are sleeved on the first rotating shaft 2, and the two first limiting rings 23 respectively abut against the left and right sides of the part of the wiping cloth 4 wound on the first rotating shaft 2. In this way, the two first limiting rings 23 can limit the part of the wiping cloth 4 wound on the first rotating shaft 2 from left to right and upward.

[0067] Optionally, please refer to Figure 1 and Figure 2 In some embodiments, two second limiting rings 31 are provided on the second rotating shaft 3, and the two second limiting rings 31 abut against the two sides of the wiping cloth 4 on the axial direction of the second rotating shaft 3.

[0068] Specifically, two second limiting rings 31 are sleeved on the second rotating shaft 3, and the two second limiting rings 31 respectively abut against the left and right sides of the part of the wiping cloth 4 wound on the second rotating shaft 3. In this way, the two second limiting rings 31 can limit the part of the wiping cloth 4 wound on the second rotating shaft 3 from left to right and upward.

[0069] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
