Description

Technical Field

[0001] This application relates to the field of screen cleaning equipment technology, and in particular to screen cleaning devices. Background Technology

[0002] In the photovoltaic field, solar cells typically have a main grid and multiple fine grids on their surface. The main grid is used for current collection and series connection. The fine grids of adjacent cells are connected by interconnecting strips to achieve series or parallel connection between adjacent cells. Some solar cells use gridless technology, which eliminates the main grid and uses solder strips to conduct current. To ensure the reliability of photovoltaic modules, after the interconnecting strips are soldered to the cells, screen printing is often used to improve the welding tensile strength and contact between the interconnecting strips and the cells.

[0003] In the screen printing process, adhesive is printed using printing equipment. The screen is placed above the adhesive to be printed, and a squeegee is installed on top of the screen. During printing, the squeegee scrapes the adhesive, which is then printed through the mesh of the screen onto the welding points of the interconnect strips and battery cells. However, as the squeegee passes over the screen, it deforms under pressure, causing some adhesive to rub onto the adhesive being printed below. Furthermore, adhesive residue remains in the mesh of the screen during printing, resulting in adhesive residue on the screen surface and causing defects such as missed printing or misalignment.

[0004] In related technologies, operators periodically clean residual adhesive from the screen surface with a scraper while the machine is stopped to avoid affecting production. However, because the screen needs to be cleaned frequently, the cleaning operation is time-consuming, labor-intensive, costly, and inefficient. Utility Model Content

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] See Figure 1 As shown, a schematic diagram of the structure of a screen cleaning device 10 in one embodiment of this application is shown. The screen cleaning device 10 provided in one embodiment of this application includes a support mechanism 100 and a first cleaning mechanism 200, which can be used to clean residual glue on the screen surface.

[0043] The support mechanism 100 serves as a mounting base, providing support for other components. The support mechanism 100 includes a support frame 110 and a first mounting frame 120, which is connected to the support frame 110. Exemplarily, the support frame 110 is a frame structure, and its material can be stainless steel, hollow or solid aluminum alloy, or a composite material. The plate thickness can be selected from 8-20mm to provide sufficient support. Furthermore, the first mounting frame 120 and the support frame 110 are connected as an integral structure, resulting in high structural strength.

[0044] The first cleaning mechanism 200 includes a first support member 210 and a first rubber shovel 220. The first support member 210 is connected to the support frame 110 and extends horizontally to support the screen. The first rubber shovel 220 is slidably connected to the first mounting frame 120, allowing the first rubber shovel 220 to slide relative to the first mounting frame 120 when subjected to external force. Furthermore, the first rubber shovel 220 and the first support member 210 are spaced apart along the height direction, such as... Figure 1 As shown, the first adhesive scraper 220 is specifically positioned above the first support member 210. Exemplarily, the first adhesive scraper 220 can be made of stainless steel, hollow or solid aluminum alloy, or composite materials to effectively remove residual adhesive from the screen surface.

[0045] When cleaning the screen, the screen to be cleaned is placed on the first support member 210 with the glue scraping side facing outwards. The first glue scraper 220 is pushed, causing it to slide relative to the first support member 210, squeezing and removing the root of the residual glue, thereby cleaning the residual glue on the screen surface. Thus, the screen cleaning device 10 of this embodiment can quickly clean the residual glue on the screen surface using the sliding first glue scraper 220, eliminating the need for frequent machine stops, reducing operation time, improving production efficiency, and lowering cleaning costs.

[0046] Further, see Figure 2 As shown, the first support member 210 includes a support portion 211 and a limiting portion 212. The support portion 211 is connected to the support frame 110 and is a rectangular flat plate arranged horizontally. For example, the length of the support portion 211 is 380-450 mm, the width is 240-300 mm, and the height is 3-5 mm. The limiting portion 212 is connected to the support portion 211 and is an L-shaped baffle fixed to the edge of the support portion 211. For example, the length of the limiting portion 212 is 40-60 mm, the width is 8-15 mm, and the height is 3-5 mm. The limiting portion 212 protrudes from the support portion 211 in the height direction of the first support member 210, which is the same as the height direction of the screen cleaning device 10. When the screen is placed on the support part 211, the limiting part 212 can block the edge of the screen, effectively fix the screen to be cleaned, prevent the screen from shifting during the cleaning process, and ensure that the first glue scraper 220 can accurately fit the surface of the screen to remove residual glue.

[0047] See Figure 3 and Figure 4 As shown, the first shovel 220 includes a first shovel body 221 and a first handle 222. The first shovel body 221 is slidably connected to the first mounting bracket 120, with the shovel blade of the first shovel body 221 facing the first support member 210. For example, the length of the first shovel body 221 is 270-330mm. The first handle 222 is connected to the side of the first shovel body 221 away from the first support member 210. For example, the first handle 222 can be integrally formed with the first shovel body 221, or connected and fixed by bolts, welding, or other methods. When the screen is placed on the first support member 210, the shovel blade of the first shovel body 221 is in contact with the upper surface of the screen. The operator can push the first shovel 220 relative to the first support member 210 using the first handle 222, thereby using the shovel blade of the first shovel body 221 to remove residual adhesive from the surface of the screen.

[0048] Further, see Figure 2 As shown, the inner side of the first mounting bracket 120 is provided with two parallel first guide rails 121. Exemplarily, the first guide rails 121 can be formed by elongated grooves on the first mounting bracket 120, with a length of 400-600mm, a depth of 10-20mm, and a height of 10-15mm. The first adhesive spatula 220 also includes first guide protrusions 223, which are respectively disposed at both ends of the first adhesive spatula body 221. The first guide protrusions 223 slide in cooperation with the first guide rails 121. Exemplarily, the first guide protrusions 223 have a length of 15-20mm, a width of 15-20mm, and a height of 10-15mm for engaging with the first guide rails 121. The cooperation between the first guide rails 121 and the first guide protrusions 223 guides the first adhesive spatula 220, preventing deviation or tilting during sliding, which could lead to incomplete removal of residual adhesive, and also improving cleaning efficiency.

[0049] See Figure 1 and Figure 2 As shown, in some embodiments, the screen cleaning device 10 further includes a second cleaning mechanism 300, and the support mechanism 100 further includes a second mounting bracket 130, which is connected to the support bracket 110 and is used to install the second cleaning mechanism 300.

[0050] Specifically, the second cleaning mechanism 300 and the second mounting bracket 130 are both fixed to the bottom of the support frame 110 and located below the first cleaning mechanism 200 and the first mounting bracket 120. The second cleaning mechanism 300 includes a second support member 310 and a second rubber shovel 320. The second support member 310 is connected to the support frame 110 and has a frame-like structure extending horizontally. The second rubber shovel 320 is slidably connected to the second mounting bracket 130, and the second rubber shovel 320 and the second support member 310 are spaced apart along the height direction. Figure 1 As shown, the second adhesive scraper 320 is specifically positioned below the second support member 310. When the screen is placed on the second support member 310, the second adhesive scraper 320 can slide horizontally to remove residual adhesive from the bottom surface of the screen. Thus, residual adhesive on the top surface of the screen can be cleaned through the first cleaning structure, and residual adhesive on the bottom surface of the screen can be cleaned through the second cleaning structure, thereby achieving cleaning of both sides of the screen and improving cleaning efficiency.

[0051] Further, see Figure 5 and Figure 6 As shown, the second shovel 320 includes a second shovel body 321, a connector 324, and a second handle 322. The second shovel body 321 is slidably connected to the second mounting bracket 130, and the shovel blade of the second shovel body 321 faces the second support member 310. Exemplarily, the length of the second shovel body 321 is 210-270 mm. The support bracket 110 is provided with a first limiting hole 111, which is, exemplarily, a rectangular through hole with a length of 25-40 mm and a width of 15-30 mm. The connector 324 is a rectangular columnar structure, with one end connected to the second shovel body 321 and the other end passing through the first limiting hole 111 and connected to the second handle 322. When the screen is placed on the second support member 310, the shovel blade of the second shovel body 321 adheres to the lower surface of the screen. The operator can push the second glue scraper 320 relative to the second support member 310 through the second handle 322, thereby using the scraper blade of the second glue scraper body 321 to remove residual glue from the screen surface. In addition, the first limiting hole 111 can limit the connecting member 324 to limit the movement direction of the second glue scraper 320, thereby improving the residual glue cleaning effect.

[0052] See Figure 2 As shown, the second mounting bracket 130 has second guide rails 131 on both sides, for example, the second guide rails 131 can be configured as grooves. The second glue scraper 320 also includes second guide protrusions 323, which are respectively connected to both ends of the second glue scraper body 321. The second guide protrusions 323 slide in cooperation with the second guide rails 131, so that the second glue scraper 320 remains stable when sliding horizontally, avoiding the problem of residual glue being missed at the bottom of the screen due to shaking, and also improving the cleaning consistency, which is conducive to thoroughly cleaning the residual glue on the bottom surface of the screen.

[0053] Furthermore, considering that there may be residual adhesive in the mesh of the screen, this residual adhesive also needs to be cleaned. Therefore, the screen cleaning device 10 can be further optimized to clean the residual adhesive in the mesh of the screen.

[0054] See Figure 1 , Figures 7 to 9 As shown, in some embodiments, the screen cleaning device 10 further includes a pressure plate mechanism 400. The pressure plate mechanism 400 includes an operating member 410, a rotating shaft 420, a connecting assembly 430, and a pressure plate 440 connected in sequence. The operating member 410 is fixedly connected to the rotating shaft 420, and the rotating shaft 420 can be rotated by applying force to the operating member 410. For example, the operating member 410 can be configured to be composed of a rod-like structure, and the operating member 410 extends outside the support frame 110 so that the operator can apply force to the operating member 410. It should be understood that the shape of the operating member 410 is not limited to that shown in the figure. The support frame 110 is provided with a circular second limiting hole 112, and the rotating shaft 420 passes through the second limiting hole 112, thereby being rotatably connected to the support frame 110, so that the rotating shaft 420 can rotate relative to the support frame 110. The connecting assembly 430 connects the rotating shaft 420 and the pressure plate 440. The pressure plate 440 is positioned on the side of the second support member 310 opposite to the second glue scraper 320, i.e., the pressure plate 440 is located above the second support member 310. The pressure plate 440 can be a rectangular plate, and the side of the pressure plate 440 facing the second support member 310 has several top glue protrusions 441. The top glue protrusions 441 are used to insert into the mesh of the screen, thereby pushing out residual glue from the mesh of the screen. Furthermore, the shape of the top glue protrusions 441 can be adaptively designed according to the shape of the mesh of the screen to be cleaned, so that the top glue protrusions 441 can fit the mesh.

[0055] Specifically, when cleaning the screen, the screen to be cleaned is first placed on the first support member 210 with the glue scraping side facing outwards, and is fixed by the limiting parts 212 at the four corners of the first support member 210. The operator pushes the first glue scraper 220, which slides under the guidance of the first guide rail 121, thereby removing the residual glue on the surface of the screen. At this time, the pressure plate mechanism 400 is in the normal state, that is, the operating member 410 and the pressure plate 440 hang downwards under the action of gravity, so that the pressure plate 440 fits against the second mounting bracket 130. When using the pressure plate mechanism 400, the operating member 410 needs to be lifted upwards, so that the rotating shaft 420 rotates and drives the pressure plate 440 upwards through the connecting assembly 430. At this time, the screen can be placed on the second support member 310. Next, the operating component 410 is pressed down, causing the pressure plate 440 to move down and press the screen. At this time, the top adhesive protrusion 441 on the pressure plate 440 inserts into the mesh, pushing out the residual adhesive inside the mesh. Then, the second adhesive scraper 320 is pulled outward. Guided by the second guide rail 131, the second adhesive scraper 320 removes the residual adhesive extruded from the pressure plate 440 and the lower surface of the screen. Finally, it is wiped with alcohol, thereby achieving a complete cleaning of the screen.

[0056] Further, see Figure 1 and Figure 2 As shown, the support frame 110 is provided with a third limiting hole 113. The axial direction of the third limiting hole 113 is parallel to the height direction of the second bearing member 310, that is, the third limiting hole 113 is arranged in the vertical direction. For example, both inner sides of the support frame 110 are provided with protrusions, and the third limiting hole 113 is provided through these protrusions. (See reference...) Figures 7 to 9 As shown, the connecting assembly 430 includes a rotating rod 431, a connecting rod 432, and a push rod 433 that are interconnected. Specifically, one end of the rotating rod 431 is fixedly connected to the rotating shaft 420 so that the rotating rod 431 and the rotating shaft 420 remain relatively fixed. The other end of the rotating rod 431 is rotatably connected to one end of the connecting rod 432, for example, the rotating rod 431 and the connecting rod 432 are hinged by a pin. The other end of the connecting rod 432 is rotatably connected to one end of the push rod 433, for example, the connecting rod 432 and the push rod 433 are hinged by a pin. The other end of the push rod 433 is fixedly connected to the pressure plate 440 so that the push rod 433 and the pressure plate 440 remain relatively fixed. The push rod 433 extends vertically and is perpendicular to the surface of the pressure plate 440, and the push rod 433 passes through the third limiting hole 113.

[0057] When the rotating shaft 420 is rotated via the operating component 410, the rotating shaft 420 drives the rotating rod 431 to rotate. Due to the restriction of the third limiting hole 113, the rotating rod 431 pushes the push rod 433 up and down via the connecting rod 432, causing the pressure plate 440 to press or release the screen. Thus, the connecting component 430 can convert the rotational motion into the linear motion of the pressure plate 440, ensuring that the pressure plate 440 can only move up and down, so that the top adhesive protrusion 441 on the pressure plate 440 can be accurately inserted into the mesh of the screen, thereby improving the residual adhesive cleaning effect.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
