[0025] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and descriptions of the same elements will not be repeated.

[0026] The words expressing position and direction described in the utility model are all illustrated by taking the drawings as examples, but changes can also be made according to needs, and the changes made are all included in the protection scope of the utility model.

[0027] With reference to Figures 1 to 4 The utility model provides a kind of suction disc for coating device, the disc is applied in coating device, and the disc can adopt the way of vacuum adsorption and adsorb target component 200, to make target component 200 be fixed on the disc.The disc is used to be installed on carrier and can be moved under the drive of carrier, for example, the disc can be moved up and down and translation under the drive of carrier.In coating device, target component 200 is placed on support component first, then target component 200 moves from support component to disc and further moves to the coating head below and carries out coating operation. Among them, target component 200 is the component that needs to be coated by coating device.Processing. Coating device can be specifically the device that carries out coating perovskite slurry to substrate, the substrate can be used as the target component 200 adsorbed by disc, and support component can be specifically conveying belt.

[0028] The chuck for coating device comprises a first end 1 and a second end 2 opposite to each other along the height direction of the chuck, the first end 1 of the chuck can be the upper end of the chuck, and the second end 2 of the chuck can be the lower end of the chuck.

[0029] With reference to Figure 2 and Figure 3 , the first end 1 of the chuck is provided with a suction area 11 for suction of the target component 200, and one or more vacuum suction ports can be arranged in the suction area 11, which are used to generate suction force to suck the target component 200. Among them, the first end 1 of the chuck can be provided with a plurality of suction areas 11, and the plurality of suction areas 11 are spaced apart from each other.

[0030] The chuck is further provided with a recessed groove 12 recessed from the first end 1 towards the second end 2, the recessed groove 12 does not penetrate the chuck along the height direction of the chuck, and the recessed depth of the recessed groove 12 is greater than the height of the support component. When it is needed to move the target component 200 from the support component to the chuck, the carrier drives the chuck to move below the support component, and then the carrier drives the chuck to move upwards, and the recessed groove 12 of the chuck is opposite to the support component, so that when the chuck moves upwards, the recessed groove 12 of the chuck accommodates the support component to avoid interference between the solid part of the chuck and the support component. When the recessed depth of the recessed groove 12 is greater than the height of the support component, the surface of the chuck at the first end 1 can be moved above the support component to lift the target component 200 and separate the target component 200 from the support component, and at this time the target component 200 is on the chuck.

[0031] By arranging the recessed groove 12 on the chuck, the recessed groove 12 is used to accommodate the support component to prevent interference between the chuck and the support component, so that the surface of the chuck at the first end 1 can pass through the support component in the vertical direction from below the support component; by setting the depth of the recessed groove 12 to be greater than the height of the support component, when the surface of the chuck at the first end 1 moves upwards to be flush with the upper surface of the support component, the bottom of the recessed groove 12 is still spaced apart from the support component by a certain distance, at this time the chuck can be further moved upwards, so that the surface of the chuck at the first end 1 can protrude from the support component and lift the target component 200 to separate the target component 200 from the support component. In this process, the support component can not need to be moved, and a driving device matched with the support component also does not need to be arranged, and the structure of the chuck is small, and the carrier used to drive the chuck can also be relatively simple, which effectively simplifies the structure of the coating device.

[0032] In addition, in the prior art, the target component 200 needs to be moved to the suction cup of the coating platform through the lifting movement of the conveying belt first, and then the coating platform is moved to the coating position, that is, the prior art needs to control the lifting movement of the conveying belt first, and then controls the movement of the coating platform to move the target component 200 on the coating platform to the coating position. In this application, the carrier driving suction cup movement can realize the picking of the target component 200 and can move the target component 200 to the coating position, which is convenient to operate and effectively simplifies the movement steps of the target component 200; and in the prior art, the coating platform and the conveying belt need to be provided with driving structures respectively to realize the transmission of the target component 200, and in this application, only the carrier needs to be provided or connected with the driving structure to realize the transmission of the target component 200, and the structure is simpler.

[0033] The recessed groove 12 can pass through the suction cup along a first direction, which can be the length direction or the width direction of the suction cup. When the length direction of the support component is parallel to the length direction of the suction cup, the first direction can be the length direction of the suction cup; when the length direction of the support component is parallel to the width direction of the suction cup, the first direction can be the width direction of the suction cup. Therefore, when the target component 200 is lifted on the suction cup, no matter where the suction cup is located along the first direction, for example, the entire suction cup is located directly below the support component in the vertical direction, or part of the suction cup is located directly below the support component in the vertical direction, the support component is stacked above and below the recessed groove 12 and is misaligned above and below the part of the suction cup without the recessed groove 12, ensuring that the relative movement between the suction cup and the support component does not interfere.

[0034] The suction area 11 of the suction cup and the recessed groove 12 provided on the suction cup can be provided with a plurality of each. Preferably, the number of suction areas 11 is one more than the number of recessed grooves 12. Each recessed groove 12 is located between two adjacent suction areas 11. Among them, the number of recessed grooves 12 corresponds to the shape of the support component, for example, when the support component is composed of two parallel conveying belts, the recessed groove 12 can be provided with two, each recessed groove 12 corresponds to one conveying belt; when the support component is composed of more than three conveying belts or other similar components, the recessed groove 12 is also correspondingly provided to be more than three, and each recessed groove 12 corresponds to one conveying belt or other similar component. The width of the recessed groove 12 is greater than the width of the conveying belt or other similar component. The width direction of the recessed groove 12 and the width direction of the conveying belt or other similar component can be perpendicular to the first direction and the vertical direction respectively.

[0035] Reference Figure 4In order to enable the vacuum suction ports in the adsorption area 11 to generate suction force, the coating device suction disc is further provided with a plurality of vacuum connection ports 21, each of which is connected with one or more adsorption areas 11, specifically, each of which is in communication with the vacuum suction ports in one or more adsorption areas 11. The vacuum connection ports 21 can be used to connect an external vacuum device, so that the external vacuum device can extract air at the vacuum suction ports through the vacuum connection ports 21, and the vacuum suction ports can generate suction force to adsorb and fix the target component 200. The external vacuum device can be a vacuum pump.

[0036] In the present embodiment, the number of vacuum connection ports 21 is the same as the number of adsorption areas 11, and each vacuum connection port 21 is in communication with the vacuum suction ports in one adsorption area 11. The plurality of vacuum connection ports 21 can be connected to the same vacuum device, or each vacuum connection port 21 is connected to a vacuum device.

[0037] In order to facilitate the installation of the vacuum connection ports 21, the coating device suction disc is provided with a mounting groove 24 recessed from the second end 2 towards the first end 1, which is used to accommodate the vacuum connection ports 21, and the depth of the mounting groove 24 is equal to or greater than the height of the vacuum connection ports 21, so that when the vacuum connection ports 21 are arranged in the mounting groove 24, the vacuum connection ports 21 are flush with the second end 2 of the coating device suction disc, or are recessed in the second end 2 of the coating device suction disc, so as to effectively avoid interference between the vacuum connection ports 21 and the components outside the suction disc, and facilitate the installation of the vacuum connection ports 21.

[0038] When it is necessary to connect the vacuum connection ports 21 with the corresponding vacuum devices, the mounting groove 24 forms a connection space for the pipe joints of the vacuum connection ports 21 and the corresponding vacuum devices, facilitating the connection of the vacuum connection ports 21 and the pipe joints. Moreover, the provision of the mounting groove 24 shortens the distance between the vacuum connection ports 21 and the corresponding adsorption areas 11, which can facilitate the processing of the communication pipeline between the vacuum connection ports 21 and the corresponding adsorption areas 11, and can improve the vacuum efficiency. In addition, the provision of the mounting groove 24 can also reduce the weight of the carrier suction disc, facilitating the movement of the carrier suction disc.

[0039] To effectively reduce the weight of the carrier suction cup, the carrier suction cup can also be provided with a weight-reducing groove 25 recessed from the second end 2 towards the first end 1. The weight-reducing groove 25 can further reduce the weight of the carrier suction cup, facilitating the movement of the carrier suction cup. It should be noted that the size of the weight-reducing groove 25 is generally larger than the size of the mounting groove 24. When the setting position of the weight-reducing groove 25 coincides with the setting position of the mounting groove 24, for example, when the predetermined setting position of the mounting groove 24 is located within the weight-reducing groove 25, only one groove body can be machined, i.e., only the weight-reducing groove 25. The groove body is used to mount the vacuum connection port 21 and to achieve the weight reduction of the carrier suction cup, i.e., the groove body serves as both the mounting groove 24 and the weight-reducing groove 25.

[0040] In the coating device, the suction cup continuously adsorbs and fixes the target component 200 during coating. To ensure the uniformity of the coating paste on the target component 200, the coating area of the paste is larger than the area of the target component 200, so that part of the paste is coated outside the target component 200. Therefore, a mask roller is arranged outside the target component 200 in the coating device, and a container is used to receive the paste coated outside the target component 200.

[0041] Referring to Figure 2 and Figure 3 To prevent interference between the suction cup and the container for receiving the paste and ensure that the adsorption area 11 of the suction cup has sufficient area to stably adsorb the target component 200, the suction cup is provided with a recessed avoidance portion 22 from one side of the suction cup towards the inside. One end of the avoidance portion 22 extends to the second end 2, and the other end of the avoidance portion 22 is separated from the first end 1, and the avoidance portion 22 extends through the coating device suction cup in the first direction. The avoidance portion 22 can be used to avoid the container for carrying the paste to prevent interference between the suction cup and the container; and separating one end of the avoidance portion 22 from the first end 1 ensures that the setting of the avoidance portion 22 does not affect the surface area of the first end 1, and thus does not affect the area of the adsorption area 11 provided on the first end 1, ensuring that the adsorption area 11 of the suction cup has sufficient area to stably adsorb the target component 200.

[0042] Correspondingly, the opposite sides of the coating device suction cup are respectively provided with avoidance portions 22, and each avoidance portion 22 is used to avoid the container for receiving the paste located on the same side of the target component 200.

[0043] Referring to Figure 4In order to facilitate the support of the carrier to the suction disc of the coating device, the second end 2 of the suction disc is provided with a plurality of support portions 23, each of which is provided with a support groove 231, and the carrier is provided with a plurality of support columns. The number of support portions 23 is the same as and corresponds to the number of support columns, and the plurality of support portions 23 cooperates with the plurality of support columns to enable the carrier to support the suction disc in multiple points. Moreover, the cooperation of the wall forming the support groove 231 with the support column can also enable the carrier to drive the synchronous movement of the suction disc when moving horizontally and vertically.

[0044] The plurality of support grooves 231 can include one or more shapes. For example, the plurality of support grooves 231 are all cylindrical grooves, tapered grooves, "V"-shaped grooves or wedge-shaped grooves; or the plurality of support grooves 231 can include multiple shapes, for example, at least two of the plurality of support grooves 231 include cylindrical grooves, tapered grooves, "V"-shaped grooves and wedge-shaped grooves. In the embodiment, the support portion 23 of the suction disc is provided with three, each of which forms a support groove 231 with a different shape, one support portion 23 forms a cylindrical groove, one support portion 23 forms a tapered groove, and one support portion 23 forms a "V"-shaped groove.

[0045] The utility model also provides a suction disc assembly for coating device, including carrier and above-mentioned suction disc for coating device. The carrier is used for supporting the suction disc and driving the suction disc to move. The carrier can be provided with a driving device itself, so that the carrier can move and drive the suction disc to move synchronously through the driving device itself; or the carrier can be connected with an external independent driving device, and the external driving device drives the carrier to move, and the carrier drives the suction disc to move synchronously.

[0046] The carrier is provided with a support column, which is used for abutting against the support portion 23 of the suction disc, for example, one end of the support column is arranged in the support groove 231 of the support portion 23. The number of support columns is the same as and corresponds to the number of support portions 23 in the suction disc. When the suction disc is provided with three support portions 23, and one support portion 23 forms a cylindrical groove, one support portion 23 forms a tapered groove, and one support portion 23 forms a "V"-shaped groove, the carrier can be provided with three support columns, one end of one support column matched with the corresponding support portion 23 is in a tapered structure, one end of one support column matched with the corresponding support portion 23 is in a "V"-shaped structure, and one end of one support column matched with the corresponding support portion 23 is in a cylindrical structure.
