Detailed implementation manners

[0037] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present application more clearly, and therefore are only examples and cannot be used to limit the protection scope of the present application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0039] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features.

[0040] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0041] In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0042] Currently, from the perspective of the development of the market situation, the application of perovskite solar cells is becoming more and more extensive. Perovskite solar cells can be applied to lunar rovers, satellite solar panels, various sensors, detectors, as well as civilian products such as wearable electronic products and automotive power supply. Perovskite solar cells have become the power source for consumer products in many aspects. Wiping equipment and coating equipment have emerged with the development of perovskite solar cells. Coating is an essential process for preparing perovskite solar cells, and the coating process has a very important impact on the quality of perovskite solar cells, directly affecting various performance indicators such as the reliability, capacity, and lifespan of the cells.

[0043] The coating equipment is used to coat a paste slurry or a molten slurry on a substrate to fabricate a perovskite solar cell. Before coating, it is necessary to detect the slurry output situation of the coating head of the coating equipment. After the detection is completed, a wiping equipment can be used to wipe the slurry flowing out of the coating head. By detecting the slurry output situation of the coating head, the possibility of uneven coating or coating head blockage during the coating process can be reduced. By wiping the slurry flowing out of the coating head with the wiping equipment, the slurry will not drip onto the substrate in a stream before coating, thereby improving the coating effect. After one coating is completed, the wiping equipment can be used to wipe the coating head of the coating equipment, so that the slurry will not remain on the coating head, which can reduce the possibility of uneven coating or coating head blockage during the next coating process. At the same time, the slurry will not form scale on the coating head, thereby ensuring the service life of the coating equipment.

[0044] In the related art, by setting walking wheels, the automatic wiping equipment can move to automatically wipe the coating head of the coating equipment. After the wiping equipment wipes the coating head, it is necessary to manually replace the wiping part of the wiping equipment, and the wiping part cannot be automatically replaced.

[0045] To solve the above technical problems, the present application provides a wiping equipment, which includes a wiping mechanism, a moving mechanism, and a lifting mechanism; the wiping mechanism includes a clamping assembly, the clamping assembly is used to clamp the wiping part, and the clamping assembly has a wiping portion for carrying the wiping part; the moving mechanism is connected to the wiping mechanism and is used to drive the wiping mechanism to move; the lifting mechanism is detachably engaged with the clamping assembly.

[0046] By connecting the wiping mechanism to the moving mechanism, the moving mechanism can drive the wiping mechanism to move from the position of the lifting mechanism to the position to be wiped of the coating device, so as to wipe the coating head of the coating device. After the wiping mechanism finishes wiping, it drives the wiping mechanism to move to the position of the lifting mechanism. The lifting mechanism can move towards the wiping mechanism to cooperate with the wiping mechanism to drive the clamping assembly to open, so that the wiping piece drops; the lifting mechanism can also move away from the wiping mechanism to release the cooperation with the wiping mechanism, so that the clamping assembly closes and clamps a new wiping piece, thus realizing the automatic replacement of the wiping piece.

[0047] The coating device disclosed in the embodiments of the present application can be used to uniformly coat materials such as glue, slurry, coating, or graphite with specific functions on the surfaces of substrates such as films, papers, fabrics, or glasses. The wiping device is used to hold a wiping piece to wipe the coating head of the coating device. The coating device disclosed in the embodiments of the present application can be widely applied in multiple fields such as new energy, textiles, construction, transportation vehicles, integrated circuits, etc. For example, in the new energy field, the coating device can prepare solar cells, that is, coat functional layers such as a conductive layer, a hole transport layer, a perovskite layer, an electron transport layer, and an electrode layer on a substrate, and can also be used to prepare the positive and negative electrodes of lithium batteries, that is, coat a thin film on the surface of the electrode material to improve the performance of the electrode; in the textile field, the coating device can also coat, cover, or print various coatings, inks, glues, etc. on fabrics; in the integrated circuit field, the coating device can coat a protective layer on a circuit board, thereby improving the quality and reliability of the circuit board.

[0048] For the convenience of description in the following embodiments, a wiping device and a coating device according to the embodiments of the present application are taken as examples for description.

[0049] Please refer to Figures 1 to 2 , Figure 1 which is a schematic structural diagram of the wiping device provided by the present application; Figure 2 which is an exploded structural diagram of the wiping mechanism of the wiping device provided by the present application. According to some embodiments of the present application, a wiping device 100 is provided. The wiping device 100 includes a wiping mechanism 110, a moving mechanism 130, and a lifting mechanism 140. The wiping mechanism 110 includes a clamping assembly 111. The clamping assembly 111 is used to hold a wiping piece 120. The clamping assembly 111 has a wiping portion 1111a. The wiping portion 1111a is used to carry the wiping piece 120. The moving mechanism 130 is connected to the wiping mechanism 110 and is used to drive the wiping mechanism 110 to move. The lifting mechanism 140 is detachably cooperated with the clamping assembly 111.

[0050] The wiping mechanism 110 clamps the wiping member 120 through the clamping assembly 111. When the clamping assembly 111 clamps the wiping member 120, at least part of the wiping member 120 covers the wiping portion 1111a, or at least part of the wiping member 120 covers the wiping portion 1111a. Supported by the wiping portion 1111a, the wiping member 120 can wipe the coating head 200 of the coating device 1000.

[0051] The wiping member 120 can be a lint-free cloth, lint-free paper, sponge, etc., but is not limited thereto. The wiping member 120 can be a dry wiping member, and a solvent can be sprayed onto the dry wiping member before wiping. Of course, the wiping member 120 can also be a wet wiping member containing a solvent. The solvent sprayed onto the dry wiping member and the solvent contained in the wet wiping member can be terpineol, butyl carbitol, butyl carbitol acetate, ethyl acetate, methyl acetate, citric acid, baking soda, N-methylpyrrole, dichloromethane, perchloroethylene, etc., but is not limited thereto.

[0052] Please refer to Figures 3 to 4 , Figure 3 which is a schematic structural diagram of an embodiment of the wiping device provided by the present application; Figure 4 which is a schematic structural diagram of another embodiment of the wiping device provided by the present application. The moving mechanism 130 is used to drive the wiping mechanism 110 to move from the position of the lifting mechanism 140 to the position to be wiped of the coating device 1000 to wipe the coating head 200 of the coating device 1000, and after the wiping mechanism 110 finishes wiping, drive the wiping mechanism 110 to move to the position of the lifting mechanism 140 to replace the wiping member 120. Specifically, the moving mechanism 130 is used to drive the wiping mechanism 110 to move from the first position to the second position, or from the second position to the first position. Among them, the first position is the position where the wiping mechanism 110 replaces the wiping member 120, and the second position is the position to be wiped of the coating device 1000. The moving mechanism 130 is also used to drive the wiping mechanism 110 to move at the second position to drive the wiping member 120 on the wiping portion 1111a to wipe the coating head 200. By driving the wiping member 120 on the wiping portion 1111a to wipe the coating head 200 through the moving mechanism 130, the automatic wiping of the wiping mechanism 110 is realized, and a fixed wiping force can be maintained, thereby ensuring the consistency of wiping, improving the wiping effect and wiping efficiency.

[0053] When the wiping mechanism 110 is in the first position, the lifting mechanism 140 is located above the wiping mechanism 110. The lifting mechanism 140 is detachably engaged with the clamping assembly 111. Specifically, when the wiping mechanism 110 is in the first position, the lifting mechanism 140 can move towards the wiping mechanism 110 to cooperate with the wiping mechanism 110 to drive the clamping assembly 111 to open, so as to release the wiping member 120, and the wiping member 120 drops by gravity, that is, the wiping member 120 is automatically discarded; the lifting mechanism 140 can also move away from the wiping mechanism 110 to disengage from the wiping mechanism 110, so that the clamping assembly 111 closes to clamp a new wiping member 120.

[0054] In some embodiments, when the wiping mechanism 110 is in the first position, after the lifting mechanism 140 drives the clamping assembly 111 to open, if the wiping member 120 cannot drop, the moving mechanism 130 can also drive the wiping mechanism 110 to tilt, vibrate or swing slightly, so as to realize the dropping of the wiping member 120 by gravity, that is, the wiping member 120 is automatically discarded.

[0055] In some embodiments, the surface area of the wiping member 120 is larger than the bearing area of the wiping portion 1111a, so that when the wiping member 120 is borne on the wiping portion 1111a, at least part of the wiping member 120 hangs on the outer edge of the wiping portion 1111a. When the wiping mechanism 110 is in the first position, after the lifting mechanism 140 drives the clamping assembly 111 to open, the part of the wiping member 120 hanging on the outer edge of the wiping portion 1111a will drive the part of the wiping member 120 borne on the wiping portion 1111a to drop from the wiping portion 1111a under the action of gravity, so as to realize the automatic discard of the wiping member 120.

[0056] The wiping device 100 further includes a bracket 180. The moving mechanism 130 is arranged at one end of the bracket 180, and the lifting mechanism 140 is arranged at the other end of the bracket 180. The bracket 180 is used to support and carry the moving mechanism 130 and the lifting mechanism 140, so that the wiping device 100 can be integrally designed, which is beneficial to the overall structural stability and matching accuracy of the device. In addition, the wiping device 100 can also be relatively fixed to the coating head 200 of the coating device 1000 through the bracket 180, or the wiping device 100 can be integrally designed with the coating device 1000 as a component of the coating device 1000, which is beneficial to the overall structural stability and matching accuracy of the device.

[0057] By connecting the wiping mechanism 110 to the moving mechanism 130, the moving mechanism 130 can drive the wiping mechanism 110 to move from the position of the lifting mechanism 140 to the position to be wiped of the coating device 1000, so as to wipe the coating head 200 of the coating device 1000. After the wiping mechanism 110 finishes wiping, it drives the wiping mechanism 110 to move to the position of the lifting mechanism 140. The lifting mechanism 140 can move towards the wiping mechanism 110 to cooperate with the wiping mechanism 110 to drive the clamping assembly 111 to open, so that the wiping piece 120 drops; the lifting mechanism 140 can also move away from the wiping mechanism 110 to release the cooperation with the wiping mechanism 110, so that the clamping assembly 111 closes and clamps a new wiping piece 120, thereby realizing the automatic replacement of the wiping piece 120.

[0058] According to some embodiments of the present application, please continue to refer to Figure 2 , the clamping assembly 111 includes a body portion 1111, a fixing member 1112, and a swinging member 1113. The body portion 1111 is formed with a wiping portion 1111a and a first clamping portion 1111b connecting the wiping portion 1111a. The fixing member 1112 is disposed on the side wall of the first clamping portion 1111b away from the wiping portion 1111a. The fixing member 1112 is provided with a first through hole 1112a. The swinging member 1113 includes a pressing portion 1113a and a second clamping portion 1113b. The pressing portion 1113a is swingably disposed on the fixing member 1112. The pressing portion 1113a is provided with a second through hole 1113c corresponding to the first through hole 1112a. The second clamping portion 1113b extends from the pressing portion 1113a towards the first clamping portion 1111b and at least partially abuts against the first clamping portion 1111b in a releasable manner.

[0059] The first clamping portion 1111b of the body portion 1111 is used to cooperate with the second clamping portion 1113b of the swinging member 1113 to clamp the wiping piece 120. The wiping portion 1111a of the body portion 1111 is used to support the wiping piece 120, so as to facilitate wiping the coating head 200 of the coating device 1000. The body portion 1111 can adopt various shapes and various sizes. For example, square, rectangular, polygonal, circular, oval, etc. The specific shape and size of the body portion 1111 are not limited, and the specific shape of the body portion 1111 can be determined according to the specific shapes and sizes of the clamping assembly 111 and the coating head 200 of the coating device 1000.

[0060] The fixing member 1112 is disposed on the side wall of the first clamping portion 1111b away from the wiping portion 1111a. The fixing member 1112 can be integrally formed with the main body portion 1111. The integrally formed structure not only ensures the structural strength of the fixing member 1112 and the main body portion 1111, but also simplifies the number of parts of the clamping assembly 111, thereby improving the assembly efficiency. The fixing member 1112 can also be fixedly connected to the main body portion 1111. The fixing connection method can be riveting, welding, bonding, bolt connection, key connection, snap connection or magnetic adsorption connection, but is not limited thereto.

[0061] In some embodiments, the fixing member 1112 includes a fixing portion 1112b, two first limiting portions 1112c and a supporting portion 1112d. The fixing portion 1112b is disposed on the side wall of the first clamping portion 1111b away from the wiping portion 1111a. The end face of the fixing portion 1112b facing the swinging member 1113 protrudes from the surface of the main body portion 1111 facing the swinging member 1113. The supporting portion 1112d is disposed on the side of the swinging member 1113 facing away from the main body portion 1111, and is disposed away from the end face of the fixing portion 1112b facing the swinging member 1113. The two first limiting portions 1112c are oppositely disposed on the side of the supporting portion 1112d facing the swinging member 1113, and are connected to the fixing portion 1112b. The first through hole 1112a is provided in the supporting portion 1112d.

[0062] The second clamping portion 1113b extends from the pressing portion 1113a towards the first clamping portion 1111b. The second clamping portion 1113b can swing in a direction opposite to the swinging direction of the pressing portion 1113a as the pressing portion 1113a swings, so that the second clamping portion 1113b abuts against the first clamping portion 1111b or releases the abutment with the first clamping portion 1111b, that is, the second clamping portion 1113b closes or opens relative to the first clamping portion 1111b. When the second clamping portion 1113b abuts against the first clamping portion 1111b, it can clamp a new wiping member 120. When the second clamping portion 1113b releases the abutment with the first clamping portion 1111b, the wiping member 120 clamped by the clamping assembly 111 drops off.

[0063] Specifically, when the pressing portion 1113a swings towards the fixing member 1112, the second clamping portion 1113b swings away from the first clamping portion 1111b to release the abutment with the first clamping portion 1111b, so that the wiping member 120 clamped by the clamping assembly 111 drops by gravity. When the pressing portion 1113a swings away from the fixing member 1112, the second clamping portion 1113b swings towards the first clamping portion 1111b to abut against the first clamping portion 1111b and clamp a new wiping member 120.

[0064] The pressing portion 1113a and the second clamping portion 1113b of the swinging member 1113 are fixedly connected or integrally formed. The fixing connection manner between the pressing portion 1113a and the second clamping portion 1113b can be riveting, welding, bonding, bolt connection, key connection, snap connection or magnetic adsorption connection, but is not limited thereto.

[0065] In some embodiments, the swinging member 1113 further includes two second limiting portions 1113d. The two second limiting portions 1113d are oppositely arranged on the side of the pressing portion 1113a facing the fixing portion 1112b. The two second limiting portions 1113d are arranged on the side where the two first limiting portions 1112c face each other, or are arranged on the side where the two first limiting portions 1112c face away from each other.

[0066] By arranging the fixing member 1112 on the side wall of the first clamping portion 1111b away from the wiping portion 1111a, and arranging the pressing portion 1113a swingably on the fixing member 1112, the second clamping portion 1113b extends from the pressing portion 1113a towards the first clamping portion 1111b and at least partially abuts against the first clamping portion 1111b in a releasable manner. When the pressing portion 1113a swings relative to the fixing member 1112, the second clamping portion 1113b can swing in the direction opposite to the swinging direction of the pressing portion 1113a along with the swinging of the pressing portion 1113a, so that the second clamping portion 1113b releases the abutment against the first clamping portion 1111b, or the second clamping portion 1113b abuts against the first clamping portion 1111b, so as to discard the old wiping member 120 or clamp the new wiping member 120, thereby realizing the automatic replacement of the wiping member 120.

[0067] According to some embodiments of the present application, the clamping assembly 111 further includes a reset assembly 150. The reset assembly 150 is arranged between the fixing member 1112 and the pressing portion 1113a.

[0068] The reset assembly 150 is used to store the restoring force towards the pressing portion 1113a when the pressing portion 1113a swings towards the fixing member 1112, and is used to reset to push the pressing portion 1113a to swing towards the direction away from the fixing member 1112, so that the second clamping portion 1113b abuts against the first clamping portion 1111b and clamps the new wiping member 120.

[0069] The reset assembly 150 has properties such as a high elastic limit, fatigue limit, impact toughness, etc. The reset assembly 150 can be a spring, for example, a compression spring, a torsion spring, a bending spring, etc., but is not limited thereto.

[0070] In some embodiments, the reset assembly 150 includes a reset body 151, a first abutting portion 152, and a second abutting portion 153. The first abutting portion 152 is connected to one end of the reset body 151. The second abutting portion 153 is connected to the other end of the reset body 151. If two second limiting portions 1113d are provided on the side where two first limiting portions 1112c face each other, the reset body 151 is arranged between the two second limiting portions 1113d; if two second limiting portions 1113d are provided on the side where two first limiting portions 1112c face away from each other, the reset body 151 is arranged between the two first limiting portions 1112c. The first abutting portion 152 abuts against the side of the fixing portion 1112b facing the pressing portion 1113a. The second abutting portion 153 abuts against the side of the pressing portion 1113a facing the fixing portion 1112b.

[0071] By arranging the reset assembly 150 between the fixing member 1112 and the pressing portion 1113a, when the pressing portion 1113a swings in the direction towards the fixing member 1112, the reset assembly 150 can store a restoring force towards the pressing portion 1113a, and the restoring force stored by the reset assembly 150 can, when the reset assembly 150 resets, push the pressing portion 1113a to swing in the direction away from the fixing member 1112, so that the second clamping portion 1113b abuts against the first clamping portion 1111b and clamps a new wiping member 120.

[0072] Please refer to Figure 5 , Figure 5 FIG. is a schematic structural diagram of a lifting mechanism of a wiping device provided by the present application. According to some embodiments of the present application, the lifting mechanism 140 includes a driving assembly 141, a lifting rod 142, and a stopper 143. The lifting rod 142 is in transmission connection with the driving assembly 141. The inner diameters of the first through hole 1112a and the second through hole 1113c are both larger than the diameter of the lifting rod 142. The stopper 143 is arranged on the lifting rod 142, and the width of the stopper 143 in the radial direction of the lifting rod 142 is larger than the inner diameter of the second through hole 1113c, or the farthest distance of the stopper 143 relative to the lifting rod 142 is larger than the inner diameter of the second through hole 1113c.

[0073] Optionally, the stopper 143 is arranged on the lifting rod 142, and the width of the stopper 143 in the radial direction of the lifting rod 142 is larger than the inner diameter of the second through hole 1113c.

[0074] Optionally, the farthest distance of the stopper 143 relative to the lifting rod 142 is larger than the inner diameter of the second through hole 1113c.

[0075] When the wiping mechanism 110 is in the first position, the axial extension line of the lifting rod 142 is located within the second through hole 1113c and the first through hole 1112a. The lifting rod 142 is in transmission connection with the driving assembly 141. The driving assembly 141 is configured to drive the lifting rod 142 to move towards or away from the clamping assembly 111 when the wiping mechanism 110 is in the first position.

[0076] When the driving assembly 141 drives the lifting rod 142 to move towards the clamping assembly 111, the lifting rod 142 sequentially passes through the second through hole 1113c and the first through hole 1112a. The stopper 143 cannot pass through the second through hole 1113c, and thus abuts against the side of the pressing portion 1113a facing away from the fixing member 1112. The stopper 143 can push the pressing portion 1113a to swing towards the fixing member 1112 under the drive of the driving assembly 141, so that the second clamping portion 1113b opens relative to the first clamping portion 1111b to discard the old wiping member 120. When the driving assembly 141 drives the lifting rod 142 to move away from the clamping assembly 111, the lifting rod 142 sequentially passes out of the first through hole 1112a and the second through hole 1113c. The reset assembly 150 resets to push the pressing portion 1113a to swing in a direction away from the fixing member 1112 so that the second clamping portion 1113b abuts against the first clamping portion 1111b and clamps the new wiping member 120, thereby realizing the automatic replacement of the wiping member 120.

[0077] By arranging the stopper 143 on the lifting rod 142, the stopper 143 can push the pressing portion 1113a to swing towards the fixing member 1112 under the drive of the driving assembly 141, so that the second clamping portion 1113b opens relative to the first clamping portion 1111b to discard the old wiping member 120, thereby realizing the automatic discarding of the wiping member without manual discarding and having a high degree of automation.

[0078] According to some embodiments of the present application, the driving assembly 141 includes a first driving member 1411, a connecting member 1412, and a transmission rod 1413. The transmission rod 1413 is connected to the first driving member 1411 and is rotatably connected to the connecting member 1412. The lifting rod 142 is fixed to the connecting member 1412.

[0079] The output shaft of the first driving member 1411 is connected to the transmission rod 1413. The first driving member 1411 is used to drive the transmission rod 1413 to rotate, so as to drive the connecting member 1412 and the lifting rod 142 to move towards or away from the clamping assembly 111. The first driving member 1411 can be a motor, and the motor has a reliable driving function with high precision, so that the rotation speed and rotational force of the transmission rod 1413 can be reliably and accurately controlled. Furthermore, the moving speed of the connecting member 1412 and the lifting rod 142, as well as the force for the stopper 143 to push the pressing portion 1113a to swing towards the fixing member 1112, can be reliably controlled, so that the stopper 143 can push the pressing portion 1113a with a certain force at a specified speed.

[0080] The connecting member 1412 has a shaft hole, and the transmission rod 1413 passes through the shaft hole of the connecting member 1412 and is rotatably connected to the connecting member 1412. The lifting rod 142 is disposed on one side of the connecting member 1412 facing the first position. Alternatively, the connecting member 1412 has a through hole, and the lifting rod 142 passes through the through hole of the connecting member 1412 and is fixedly connected to the connecting member. Wherein, the first position is located below the lifting mechanism 140.

[0081] In some embodiments, the lifting mechanism 140 can be a ball screw structure. Of course, the lifting mechanism 140 can also be a gear-rack structure. For example, the transmission rod 1413 is a gear structure, and the lifting rod 142 is a rack structure. The gear structure meshes with the rack structure, and the lifting of the lifting rod 142 is realized through the meshing movement.

[0082] By connecting the transmission rod 1413 to the first driving member 1411, rotatably connecting it to the connecting member 1412, and fixing the lifting rod 142 to the connecting member 1412, the transmission rod 1413 can drive the connecting member 1412 and the lifting rod 142 to move towards or away from the clamping assembly 111 under the drive of the first driving member 1411, so as to drive the second clamping portion 1113b to open or close relative to the first clamping portion 1111b, thereby realizing the automatic replacement of the wiping member 120.

[0083] According to some embodiments of the present application, the lifting mechanism 140 further includes a housing 144. The housing 144 is disposed on one side of the first driving member 1411. The housing 144 is formed with a receiving groove 144a. The transmission rod 1413 is located in the receiving groove 144a. A part of the connecting member 1412 is located in the receiving groove 144a, and the other part extends out of a notch 144b of the receiving groove 144a. The lifting rod 142 is fixed to the other part of the connecting member 1412.

[0084] The housing 144 is the basic carrier of the lifting mechanism 140, and plays a role in carrying and protecting the components of the lifting mechanism 140. The housing 144 can adopt various shapes and sizes. For example, a cube, a cuboid, a cylinder, a prism, etc. The specific shape and size of the housing 144 are not limited, and the specific shape of the housing 144 can be determined according to the specific shapes and sizes of the connecting member 1412 and the transmission rod 1413.

[0085] The housing 144 is formed with a receiving groove 144a. A part of the connecting member 1412 is received in the receiving groove 144a, and the transmission rod 1413 is rotatably connected to the part of the connecting member 1412 located in the receiving groove 144a to prevent impurities such as water and dust from interfering with the rotation of the transmission rod 1413 relative to the connecting member 1412, thereby reducing the possibility of wear of the transmission rod 1413 and the connecting member 1412, and further ensuring the service life of the lifting mechanism 140. Another part of the connecting member 1412 extends out of a notch 144b of the receiving groove 144a to extend outside the receiving groove 144a, and the lifting rod 142 is fixed to the part of the connecting member 1412 extending outside the receiving groove 144a, so that the lifting rod 142 will not interfere with the housing 144 when moving.

[0086] By providing the housing 144, a part of the connecting member 1412 is received in the receiving groove 144a and rotatably connected to the transmission rod 1413, and at the same time, another part of the connecting member 1412 extends out of a notch 144b of the receiving groove 144a and is fixedly connected to the lifting rod 142. On the one hand, it can prevent impurities such as water and dust from interfering with the rotation of the transmission rod 1413 relative to the connecting member 1412, thereby reducing the possibility of wear of the transmission rod 1413 and the connecting member 1412, and further ensuring the service life of the lifting mechanism 140. On the other hand, the lifting rod 142 will not interfere with the housing 144 when moving.

[0087] According to some embodiments of the present application, please continue to refer to Figure 1 , the moving mechanism 130 includes a second driving member 131 and a connecting arm 132. One end of the connecting arm 132 is connected to the second driving member 131, and the other end is connected to the wiping mechanism 110.

[0088] The connecting arm 132 is connected between the output end of the second driving member 131 and the wiping mechanism 110. That is, the second driving member 131 is connected to the wiping mechanism 110 through the connecting arm 132 to drive the wiping mechanism 110 to move through the connecting arm 132. Specifically, the second driving member 131 is configured to drive the connecting arm 132 to move so as to drive the wiping mechanism 110 to move from the first position to the second position, or from the second position to the first position. The second driving member 131 is further configured to drive the connecting arm 132 to move to drive the wiping mechanism 110 to wipe the coating head 200 of the coating device 1000 when the wiping mechanism 110 is in the second position. The second driving member 131 is further configured to drive the wiping mechanism 110 to tilt, vibrate or swing slightly when the lifting mechanism 140 drives the clamping assembly 111 to open and the wiper 120 cannot fall, so that the wiper 120 falls by gravity.

[0089] By connecting one end of the connecting arm 132 to the second driving member 131 and the other end to the wiping mechanism 110, the second driving member 131 can drive the connecting arm 132 to move to drive the wiping mechanism 110 to move. The connecting arm 132 has a simple structure and is easy to maintain. On the one hand, it is beneficial to simplify the structure of the moving mechanism 130, and on the other hand, it reduces the maintenance cost of the moving mechanism 130.

[0090] According to some embodiments of the present application, the connecting arm 132 includes a plurality of connecting sub-arms sequentially and movably connected between the second driving member 131 and the wiping mechanism 110.

[0091] In some embodiments, the connecting sub-arm may include a first connecting sub-arm 1321, a second connecting sub-arm 1322, and a third connecting sub-arm 1323. One end of the first connecting sub-arm 1321 facing away from the second connecting sub-arm 1322 is connected to the second driving member 131. One end of the third connecting sub-arm 1323 facing away from the second connecting sub-arm 1322 is connected to the wiping mechanism 110.

[0092] The connecting arm 132 is formed by connecting in series a first connecting sub-arm 1321, a second connecting sub-arm 1322, and a third connecting sub-arm 1323. The first connecting sub-arm 1321 and the second connecting sub-arm 1322 are movably connected, and the second connecting sub-arm 1322 and the third connecting sub-arm 1323 are movably connected. Also, the first connecting sub-arm 1321, the second connecting sub-arm 1322, and the third connecting sub-arm 1323 are in transmission connection. The first connecting sub-arm 1321, the second connecting sub-arm 1322, and the third connecting sub-arm 1323 are configured to gradually transmit the driving force of the second driving member 131 to the wiping mechanism 110, so as to drive the wiping mechanism 110 to move from a first position to a second position, or from the second position to the first position. The second driving member 131 is further configured to drive the first connecting sub-arm 1321, the second connecting sub-arm 1322, and the third connecting sub-arm 1323 to move when the wiping mechanism 110 is in the second position, so as to drive the wiping mechanism 110 to wipe the coating head 200 of the coating device 1000. The second driving member 131 is further configured to drive the first connecting sub-arm 1321, the second connecting sub-arm 1322, and the third connecting sub-arm 1323 to move to drive the wiping mechanism 110 to tilt slightly, vibrate, or sway when the lifting mechanism 140 drives the clamping assembly 111 to open and the wiping member 120 cannot fall off, so that the wiping member 120 falls off by gravity.

[0093] In some embodiments, the specific number of the connecting sub-arms of the connecting arm 132 is not limited to the above number. For example, the number of the connecting sub-arms of the connecting arm 132 can be 2, 4, 5, 7, 8, 10, etc., but is not limited thereto.

[0094] The connecting arm 132 formed by connecting multiple connecting sub-arms in series has a high degree of freedom and flexibility of movement, and can accurately control the moving position and angle of the wiping mechanism 110.

According to some embodiments of the present application, the wiping device 100 further includes a storage box 160, and the storage box 160 is used for storing the wiping member 120. The storage box 160 has an opening 160a.

[0096] The storage box 160 is a carrier for the wiping member 120, and plays a role in carrying and protecting the wiping member 120. The storage box 160 has an opening 160a, and the opening 160a of the storage box 160 is for the wiping member 120 to extend out from the opening 160a. So that the wiping member 120 can be stored in the storage box 160 and extend out through the opening 160a of the storage box 160. The wiping member 120 is detachably arranged in the storage box 160. After the clamping assembly 111 clamps the wiping member 120 extending out from the opening 160a, when wiping the coating head 200 next time, during the process that the moving mechanism 130 drives the wiping mechanism 110 to move to the position to be wiped of the coating device 1000, the clamped wiping member 120 will be completely drawn out, so as to realize the automatic extraction of the wiping member 120. During the process of extracting the wiping member 120 extending out from the opening 160a of the storage box 160, the next wiping member 120 in the storage box 160 will be driven to extend out from the opening 160a.

[0097] By arranging the wiping member 120 in the storage box 160 and extending it out through the opening 160a of the storage box, the wiping member 120 is detachably arranged in the storage box 160. On the one hand, the storage box 160 can play roles such as dust-proof, waterproof, and insect-proof, reducing the possibility of the wiping member 120 being contaminated; on the other hand, it also facilitates the clamping assembly 111 to extract the wiping member 120 and is convenient for the use of the wiping member 120.

[0098] Please refer to Figure 8 , Figure 8 is a schematic structural diagram of the spraying mechanism of the wiping device provided by the present application. According to some embodiments of the present application, the wiping device 100 further includes a spraying mechanism 170.

The pipe body 172 is arranged in the liquid storage box 171 and is in internal communication with the liquid storage box 171. The driving pump 173 is arranged in the liquid storage box 171 and is in internal communication with the liquid storage box 171, and is used for driving the solvent in the liquid storage box 171 to flow out along the pipe body 172.

[0099] The liquid storage box 171 can adopt various shapes and various sizes. For example, a cube, a cuboid, a cylinder, a prism, etc. The specific shape and size of the liquid storage box 171 are not limited, and the specific shape and size of the liquid storage box 171 can be set according to the usage amount of the solvent. The solvent can be terpineol, butyl carbitol, butyl carbitol acetate, ethyl acetate, methyl acetate, citric acid, baking soda, N-methylpyrrole, dichloromethane, tetrachloroethylene, etc., but not limited thereto.

[0100] After a new wiper 120 is replaced in the wiping mechanism 110, the driving pump 173 can drive the solvent stored in the liquid storage box 171 to flow out along the pipe body 172 and be sprayed onto the wiper 120 to wet the wiper 120. The solvent can dissolve the slurry on the coating head, facilitating the wiping of the coating head 200 by the wiper 120. The wiper 120 can wipe the coating head 200 evenly, with good cleaning effect, improving the wiping effect of the wiping device 100.

[0101] In some embodiments, the spraying mechanism 170 further includes a valve 174. The valve 174 is disposed on the pipe body 172 or the driving pump 173. The valve 174 is used to adjust the flow rate of the solvent flowing out along the pipe body 172, thereby controlling the spraying duration of the spraying mechanism 170 and the wetting degree of the wiper 120.

[0102] By providing the spraying mechanism 170, the driving pump 173 of the spraying mechanism 170 can drive the solvent stored in the liquid storage box 171 to flow out along the pipe body 172 and be sprayed onto the wiper 120, thereby realizing automatic spraying of the solvent onto the wiper 120.
