[0031] Below, please refer to the appendix. Figure 1 and Figure 2 The present application describes a spray assembly 4, which includes a sleeve 401 and an extension tube 405.
[0032] The sleeve 401 has two opposite ends and forms a receiving space, and a first spray head 403 is provided on the first surface of the sleeve 401;
[0033] Specifically, the sleeve 401 can be a circular tube or a rectangular tube; the sleeve 401 has opposite ends and forms a receiving space; the sleeve 401 can be fully enclosed or quarter-enclosed; if the sleeve 401 is a circular tube, a first spray head 403 is provided on the first surface tangent to the sleeve 401; there can be multiple first spray heads 403, which are evenly spaced on the first surface of the sleeve 401. If the sleeve 401 can be a rectangular tube, and if the sleeve 401 is a fully enclosed structure, any surface of the sleeve 401 can be the first surface, and the first surface is provided with a first spray head 403; if the sleeve 401 is a quarter-enclosed structure, the first surface of the sleeve 401 is adjacent to the open surface, and the first surface is provided with a first spray head 403.
[0034] In a specific embodiment, such as Figure 1-2 As shown, the sleeve 401 is a rectangular tube with opposite ends, both ends of which are hollow; the sleeve 401 has three surfaces, one of which is an open structure.
[0035] The extension tube 405 is movably disposed within the receiving space of the sleeve 401 and can extend to at least one end of the sleeve 401. A second spray head 408 is provided on the first surface of the extension tube 405, and the first surface of the extension tube 405 is parallel to the first surface of the sleeve 401.
[0036] Specifically, the extension tube 405 is disposed within the sleeve 401 and has a shape adapted to the sleeve 401. For example, if the sleeve 401 is a circular tube, then the extension tube 405 is a circular tube; if the sleeve 401 is a rectangular tube, then the extension tube 405 is a rectangular tube. The extension tube 405 can be disposed at one or both ends of the sleeve 401, such that the extension tube 405 extends at least at one end of the sleeve 401. The first surface of the extension tube 405 is parallel to the first surface of the sleeve 401 and is provided with a second spray head 408, thereby enabling the extension tube 405 and the sleeve 401 to spray in the same direction. There can be multiple second spray heads 408, which are evenly spaced on the first surface of the extension tube 405.
[0037] In a specific embodiment, such as Figure 1-2As shown, since the sleeve 401 is a rectangular tube and the extension tube 405 is a rectangular tube, and the extension tube 405 has the same shape as the sleeve 401, the extension tube 405 is a hollow structure and has three surfaces, one of which is an open structure.
[0038] It is understandable that when the size of the extension tube 405 is smaller than the size of the sleeve 401, the extension tube 405 can move within the sleeve 401 by being placed in the receiving space formed by the sleeve 401. In other words, the extension tube 405 can move from one end of the sleeve 401 to the other end.
[0039] In this application, by providing an extension tube 405 inside the sleeve 401, the length of the sleeve 401 can be increased, thereby adjusting the spray range of the spray assembly 4, which can be applied to photovoltaic cells of different sizes.
[0040] In one alternative approach, such as Figure 1 and Figure 2 As shown, a first groove 402 is provided on the first surface of the sleeve 401, and a first spray head 403 is disposed in the first groove 402. There are multiple first grooves 402, and the multiple first grooves 402 are adapted to the first spray head 403 and disposed on the first surface of the sleeve 401.
[0041] In one alternative approach, such as Figure 1 and Figure 2 As shown, a second groove 407 is provided on the first surface of the extension tube 405, and a second spray head 408 is disposed in the second groove 407. A plurality of second grooves 407 are adapted to the second spray head 408 and disposed on the first surface of the extension tube 405.
[0042] In an alternative embodiment, the spray assembly 4 further includes a connecting pipe 404 disposed between the sleeve 401 and the extension pipe 405 for further extending the extension pipe 405 and / or restricting the movement of the extension pipe 405 within the sleeve 401.
[0043] Specifically, the connecting pipe 404 is disposed between the extension pipe 405 and the sleeve 401, and has a shape adapted to the sleeve 401. For example, if the sleeve 401 is a circular pipe, then the connecting pipe 404 is a circular pipe; if the sleeve 401 is a rectangular pipe, then the connecting pipe 404 is a rectangular pipe. The connecting pipe 404 is disposed between the extension pipe 405 and the sleeve 401. In one specific embodiment, the connecting pipe 404 can extend out of the sleeve 401, thereby further increasing the movement area of the extension pipe 405 extending from the sleeve 401, thus extending the movement area of the extension pipe 405. In another specific embodiment, the connecting pipe 404 is disposed within the sleeve 401 or is provided with a limiting device 406, thereby reducing the area of the extension pipe 405 extending from the sleeve 401, thus restricting the movement area of the extension pipe 405.
[0044] In a specific embodiment, such as Figure 1-2 As shown, since the sleeve 401 and the extension tube 405 are rectangular tubes, the connecting tube 404 is a rectangular tube, and the connecting tube 404 has the same shape as the sleeve 401, the connecting tube 404 is a hollow structure and has three surfaces, one of which is an open structure.
[0045] It is understandable that when the size of the connecting tube 404 is smaller than the size of the sleeve 401 but larger than the size of the extension tube 405, the connecting tube 404 can be positioned between the sleeve 401 and the extension tube 405, thereby enabling the connecting tube 404 to move within the sleeve 401 and to extend the extension tube 405 or restrict the movement area of the extension tube 405.
[0046] In one alternative embodiment, a limiting device 406 is provided on the connecting pipe 404 to restrict the movement of the extension pipe 405 within the sleeve 401. In a specific embodiment, the limiting device 406 can be a limiting nut, which is fixedly disposed on the connecting pipe 404, for example, by a threaded connection. The limiting nut can be on any surface of the connecting pipe 404; preferably, it is disposed on a surface other than that parallel to the extension pipe 405.
[0047] In a specific embodiment, such as Figure 1-2 As shown, a limiting nut is provided on the connecting pipe 404 on the surface adjacent to the first surface of the extension pipe 405. The limiting nut is provided on the connecting pipe 404 by means of a threaded connection. Since the limiting nut protrudes from the surface adjacent to the first surface of the sleeve 401, the movement area of the connecting pipe 404 is restricted when the limiting nut approaches the sleeve 401, and the formation of the diffraction tube in the connecting pipe 404 is also restricted.
[0048] The second aspect of this application also provides a spraying device, including a spraying component 4 provided in the first aspect of this application.
[0049] In one alternative embodiment, the spraying device includes a housing 1, with a spraying chamber 2 formed inside the housing 1, and a spraying assembly 4 disposed inside the spraying chamber 2.
[0050] Specifically, the box 1 can be a cylinder, cube, or cuboid, and the box 1 can have a fully enclosed, semi-enclosed, or other structures, such as... Figure 3 As shown, the box 1 is a semi-enclosed cuboid structure with six surfaces. The six surfaces can be divided into an upper surface, a lower surface, and four side surfaces. The upper and lower surfaces are provided with shells, and the two opposite side surfaces of the four side surfaces are semi-enclosed structures. The six surfaces form the box 1, and the spray chamber 2 is formed in the box 1.
[0051] In one alternative embodiment, the spraying equipment further includes a liquid supply assembly 3, which includes a liquid supply tank 301, a liquid supply pump 302, and a liquid supply main pipe 303; the liquid supply pump 302 is connected to the liquid supply tank 301; the liquid supply main pipe 303 is connected to the liquid supply pump 302, and a liquid supply branch pipe 304 is provided at the lower end of the liquid supply main pipe 303, and each liquid supply branch pipe 304 is connected to a single sleeve 401.
[0052] Specifically, such as Figure 3 and Figure 5 As shown, the liquid supply tank 301 in the liquid supply assembly 3 is located on the outside of the side of the tank body 1; the liquid supply pump 302 and part of the liquid supply main pipe 303 are located above the upper surface of the tank body 1. The liquid supply main pipe 303 includes multiple liquid supply branch pipes 304. The multiple liquid supply branch pipes 304 penetrate the upper surface of the tank body 1 and are connected to the sleeve 401 on the spray assembly 4 located below the tank body 1, thereby realizing the delivery and spraying of the spray liquid.
[0053] In one alternative approach, such as Figure 3 and Figure 6 As shown, the liquid supply equipment also includes a storage component, which includes a storage device 6; the storage device 6 is located below the spray chamber 2 and is used to place the object to be sprayed.
[0054] It is understood that the object to be sprayed in this application mainly refers to solar cells, but if other items such as silicon wafers or flat panels are also suitable for this spraying equipment, this spraying equipment is not limited.
[0055] In one alternative approach, such as Figure 3 and Figure 6 As shown, the storage assembly also includes a slide rail 5; the slide rail 5 is movably disposed on both sides of the spray chamber 2, and the storage device 6 is disposed on the slide rail 5.
[0056] In a specific embodiment, such as Figure 3 and Figure 6 As shown, the placement device 6 includes a mesh plate 601 and a limiting component. The mesh plate 601 is disposed below the spray chamber 2 and is used to place the object to be sprayed; the limiting component is disposed on the mesh plate 601 and is used to form the placement position of the object to be sprayed.
[0057] In a more specific embodiment, such as Figure 3 and Figure 6 As shown, the limiting assembly consists of at least one limiting member 602 and a fastener 603; the fastener 603 sets the limiting member 602 on the mesh plate 601. In a specific embodiment, the limiting member 602 is an L-shaped limiting angle with a screw; the fastener 603 is a nut. By inserting the L-shaped limiting angle with the screw into the mesh plate 601 and connecting it to the screw with the nut, the limiting assembly is positioned on the mesh plate 601. When four limiting assemblies are arranged on the mesh plate 601 according to the shape of the battery cells, the placement position of the battery cells, i.e., the object to be sprayed, can be effectively limited.
[0058] In one alternative approach, such as Figure 3 and Figure 4 As shown, the spray assembly 4 also includes a drainage assembly for discharging waste liquid. Specifically, the drainage assembly includes a guide plate 7 and a waste liquid discharge pipe 8; the guide plate 7 is disposed at the lower end of the housing 1, and the waste liquid discharge pipe 8 is disposed at one end of the guide plate 7. In a specific embodiment, the guide plate 7 is inclined downwards towards the lower part of the housing 1, and the waste liquid discharge pipe 8 is disposed at the end of the guide plate 7 near the lower part of the housing 1. Thus, when the sprayed waste liquid falls onto the guide plate 7, the waste liquid can flow down with the angle of inclination and out through the waste liquid discharge pipe 8.
[0059] The structure and process of the spray assembly 4 of the first aspect and the spray device of the second aspect of this application are described below with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not a specific limitation of this application.
[0060] like Figure 3-4 As shown, the spraying equipment includes a housing 1. The upper half of the housing 1 is hollow and forms a spraying chamber 2. A liquid supply component 3 is provided outside the housing 1. The outlet end of the liquid supply component 3 is connected to the spraying component 4. The spraying component 4 is installed inside the upper part of the spraying chamber 2. Slide rails 5 are fixedly installed on both sides of the spraying chamber 2 inside the housing 1. A placement device 6 for placing battery cells is slidably engaged on the slide rails 5. When spraying the battery cells, the battery cells are placed on the placement device 6 and pushed into the spraying chamber 2 of the housing 1 through the slide rails 5. By adjusting the spraying component 4, the spraying range can be adjusted according to the size of the battery cells, thus making it suitable for spraying battery cells of different sizes.
[0061] A guide plate 7 is fixedly installed at the lower end of the interior of the housing 1. The guide plate 7 is inclined and positioned below the storage device 6. A waste liquid discharge pipe 8 is provided at the end of the guide plate 7 near the lower part of the housing 1. During the spraying process, the spraying waste liquid falls from the storage device 6 and lands on the guide plate 7. The waste liquid can flow down with the angle of inclination and flow out from the waste liquid discharge pipe 8, thus avoiding the accumulation of waste liquid.
[0062] Both ends of the slide rail 5 extend to the outside of the housing 1. When the storage device 6 is pulled out of the spray chamber 2, the slide rail 5 can support the storage device 6 and improve the stability of picking up and putting in the battery cells.
[0063] The liquid supply assembly 3 includes a liquid supply tank 301 with a liquid injection port. The liquid supply tank 301 is fixedly installed on the outer side of the housing 1. The input end of the liquid supply pump 302 is connected to the liquid supply tank 301. The liquid supply pump 302 supplies the liquid inside the liquid supply tank 301 into the interior of the spray assembly 4 to spray the battery cells.
[0064] A main supply pipe 303 is fixedly installed at the output end of the liquid supply pump 302. A series of branch supply pipes 304 are fixedly installed at the lower end of the main supply pipe 303. Valves 305 and 305 are fixedly installed on the main supply pipe 303 between the branch supply pipes 304. The spray assembly 4 is fixedly installed at the lower end of the branch supply pipes 304. When processing the spraying process, the industrial assembly opens and closes the valves 305 and 305 according to the size of the battery cell to adjust the spraying range. For example, the branch supply pipes 304 on both sides can be shut off, and only the branch supply pipe 304 near the middle can be supplied with liquid, so that the spray assembly 4 near the middle can perform spraying operation.
[0065] The spray assembly 4 includes a sleeve 401. The lower surface of the sleeve 401 is evenly spaced with a plurality of first grooves 402. A first spray head 403 is fixedly installed inside each first groove 402. When the liquid supply branch pipe 304 supplies liquid, the spray solution enters the inside of the sleeve 401 and is then sprayed out through the first spray head 403 to spray the battery cells.
[0066] Connecting pipes 404 are fixedly installed at both ends of the sleeve 401, and an extension pipe 405 is inserted into the inside of the sleeve 401. A limiting nut 406 is threadedly connected to one side of the connecting pipe 404, and one side of the limiting nut 406 contacts the extension pipe 405. Multiple second grooves 407 are evenly spaced on the lower surface of the extension pipe 405. A second spray head 408 is fixedly installed inside each second groove 407. In use, the spray range is adjusted according to the size of the battery cell and the connecting pipe 404. During adjustment, the limiting nut 406 is loosened first, and the extension pipe 405 is pushed and pulled, so that the extension pipe 405 moves inside the sleeve 401 through the connecting pipe 404, so that the sleeve 401 blocks the second spray head 408 that enters the sleeve 401, thereby achieving the effect of adjusting the lateral spray range. After adjustment, the limiting nut 406 is tightened to fix the extension pipe 405 for easy use.
[0067] The storage device 6 includes a storage mesh plate 601. The two sides of the storage mesh plate 601 are slidably engaged with the slide rail 5. An L-shaped limiting member 602 is fixedly installed on the mesh plate 601. A threaded rod 603 that mates with a nut is fixedly installed at the lower end of the limiting member 602. The threaded rod 603 is inserted into the hole of the storage mesh plate 601, and the nut on the threaded rod 603 contacts the lower surface of the storage mesh plate 601. In use, the position of the limiting member 602 is adjusted according to the size of the external battery cell. There are four limiting members 602, which are L-shaped, so that the limiting members 602 form a frame to limit the battery cell, which facilitates the placement of the battery cell. When installing the limiting member 602, the threaded rod 603 on the limiting member 602 is inserted into the mesh hole on the storage mesh plate 601, and the nut is tightened at the lower end of the limiting member 602 to achieve the effect of fixing the limiting member 602.
