Description

Technical Field

[0001] The utility model relates to the field of semiconductor cleaning, in particular to a cleaning tank and photovoltaic equipment. Background Art

[0002] Cleaning is a crucial step in silicon wafer electroplating production. A common post-plating cleaning method involves immersing the plated wafers in a cleaning tank for direct chemical cleaning to remove residual chemicals, impurities, and contaminants from the wafer surface. However, this method is inefficient, resulting in poor cleaning results and consuming a large amount of cleaning fluid, failing to achieve the desired results of improving quality, reducing costs, and increasing efficiency.

[0003] To address the aforementioned issues, existing technologies offer a novel cleaning method for silicon wafers using a nozzle. This nozzle cleaning utilizes a high-pressure jet system to spray cleaning fluid onto the wafer surface at high velocity, effectively removing residual chemicals and impurities. This not only improves cleaning effectiveness and efficiency, but also reduces the amount of cleaning fluid used, significantly reducing cleaning costs. However, the splashing water column generated by spray cleaning can easily interfere with other mechanisms, causing contamination and even mechanical failure, thereby shortening service life and increasing repair and maintenance costs. Furthermore, the splashing water column wastes cleaning fluid, resulting in a high cost for cleaning fluid.

[0004] Based on the above, there is an urgent need for a cleaning tank and photovoltaic equipment to solve the problems existing in the existing technology. Utility Model Content

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0057] The cleaning tank and photovoltaic equipment provided by the present invention are described below in conjunction with the accompanying drawings and specific embodiments. It should be noted in advance that the cleaning tank of this embodiment is used to clean solar cells, such as solar cells after texturing, electroplating, film stripping, and etching processes. In the drawings of this embodiment, the one-way arrow marked X represents the horizontal first direction, which is the direction of movement of the solar cell during cleaning. The two-way arrow marked Y represents the horizontal second direction, and the two-way arrow marked Z represents the vertical direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. The parts to be cleaned in this application can also be raw materials, semi-finished products, or finished products. For example, when the parts to be cleaned are solar cells, the solar cells can be silicon wafers, semi-finished solar cells, or finished solar cells.

[0058] Of course, it is understandable that in other embodiments, the cleaning tank can also be used to clean other parts to be cleaned, such as printed circuit boards or semiconductor chips, to remove surface dirt, grease or chemical residues on the parts to be cleaned.

[0059] Specifically, the cleaning tank includes a tank body 1, a spray pipe 2 and a liquid blocking structure.

[0060] In this embodiment, combined with Figures 1 to 4 As shown, the tank body 1 specifically includes a bottom plate 11 and a base frame 12. The bottom plate 11 is horizontally fixed on a horizontal plane. The length of the bottom plate 11 is parallel to the direction of arrow X. Two base frames 12 are spaced apart on the bottom plate 11 in the direction of arrow X. The space between the two base frames 12 defines a cleaning area 101. A liquid inlet is also provided on the bottom plate 11 between the two base frames 12. The cleaning area 101 is connected to an external liquid supply device through the liquid inlet. The external liquid supply device is loaded with cleaning liquid for cleaning battery cells. The composition of the cleaning liquid is not limited in this embodiment. In addition, the base frame 12 can be fixed to the bottom plate 11 by welding, bonding, etc. When manufacturing the cleaning tank, the above-mentioned bottom plate 11 and two base frames 12 are first assembled to form the external frame of the cleaning tank.

[0061] Furthermore, if Figure 4 As shown, the base frame 12 is U-shaped when viewed in the direction of arrow X, so as to form a avoiding space 121 on the base frame 12 to prevent the battery cells from entering or leaving the cleaning area 101 .

[0062] In this embodiment, Figure 3 As shown, the spray pipe 2 extends in the direction of arrow Z and is arranged in the cleaning area 101. A spray port is opened on the side wall of the spray pipe 2. The spray port is connected to the liquid inlet and is aligned with the battery cells arranged in the cleaning area 101, so that the cleaning tank can clean the battery cells entering the cleaning area 101 by spraying. Compared with immersion cleaning, the cleaning effect is better and the cleaning efficiency is higher. It can also effectively reduce the use of cleaning liquid, thereby reducing the cleaning cost.

[0063] Preferably, in this embodiment, Figure 5 As shown, the opening of the cleaning area 101 includes an entrance to the cleaning area 101 and an exit from the cleaning area 101 arranged in sequence along the direction of arrow X; and along the X direction, two spray pipes 2 are arranged at intervals in the cleaning area 101 to perform secondary cleaning on the battery cells at two positions close to the entrance of the cleaning area 101 and close to the exit of the cleaning area 101, thereby effectively improving the cleaning quality of the battery cells.

[0064] More preferably, reference Figure 1 and Figure 2 As shown, in this embodiment, a plurality of pairs of spray pipe groups with two spray pipes 2 as a pair are arranged in the cleaning area 101 at intervals along the direction of arrow Y, so that the cleaning tank can clean multiple battery cells at the same time, so that the cleaning tank can meet the one-time large-scale cleaning requirements, thereby greatly improving the cleaning efficiency and saving time.

[0065] Optionally, the cleaning tank further includes a nozzle 4 disposed on the spray pipe 2. The nozzle 4 has a nozzle opening that is connected to the spray port and is aimed at the battery cells disposed in the cleaning area 101. Because the cleaning tank can control the amount of liquid output by adjusting the valve and flow meter connected to the spray pipe 2, the spray pressure of the cleaning liquid can be automatically adjusted according to factors such as the structural strength of the battery cell itself and the distance between the battery cell and the spray pipe 2, thereby greatly reducing the probability of the battery cell being shattered by the liquid column.

[0066] Furthermore, if Figure 3 As shown, the spray pipe 2 is provided with a plurality of nozzles 4 spaced apart along the direction of arrow Z (i.e., along the length of the spray pipe 2). The spraying range of the nozzles 4 is preferably circular, so that the cleaning liquid can be sprayed on the battery cells over a wider range, thereby further improving the cleaning effect and cleanliness of the battery cells. It is worth noting that in this embodiment, the spraying direction of the cleaning liquid is arranged in the direction of arrow X. This allows the cleaning liquid to be sprayed simultaneously on two battery cells located on both sides of the spray pipe 2. In other words, a battery cell can be cleaned by the cleaning liquid sprayed by the nozzles 4 on two groups of spray pipes at the same time, thereby further helping to further improve the cleaning effect of the battery cells.

[0067] Optionally, the cleaning tank further includes a first connecting structure, through which the spray pipe 2 is detachably connected to the nozzle 4, thereby facilitating assembly and disassembly of the nozzle 4 from the spray pipe 2 and saving time in installation and maintenance of the nozzle 4. For example, in this embodiment, the first connecting structure is a quick-release connector.

[0068] Optionally, in this embodiment, the cleaning tank further includes a side plate 5 , a mounting plate 6 , a second connecting structure 7 , a third connecting structure 8 and a fourth connecting structure 9 .

[0069] Specifically, if Figure 6 As shown, the side plate 5 is vertically fixedly connected to the base frame 12. One specific implementation of this embodiment is that the side plate 5 adopts a grid structure, the side plate 5 is perpendicular to the direction of arrow X, and is adaptively arranged in the avoidance space 121 of the base frame 12, and a plurality of grid holes 501 are arranged side by side along the direction of arrow Y on the plate surface, a grid hole 501 is formed between two adjacent grid bars 51, and the plurality of grid holes 501 are all connected to the avoidance space 121 of the base frame 12, so that a plurality of battery cells can pass through the grid holes 501 and the avoidance space 121 in turn into the cleaning area 101.

[0070] like Figure 7As shown, the mounting plate 6 is detachably connected to the top of the side plate 5 via the second connecting structure 7, so that the mounting plate 6 is fixed above the bottom plate 11 of the tank body 1 through the side plate 5, thereby providing a certain height space for the vertical installation of the spray pipe 2. The provision of the second connecting structure 7 can increase the flexibility of the mounting plate 6 and the side plate 5, thereby facilitating transportation and maintenance. For example, in this embodiment, referring to Figure 6 As shown, the second connection structure 7 adopts a mortise and tenon structure. The setting of the mortise and tenon structure can effectively enhance the installation stability between the mounting plate 6 and the side plate 5, and is convenient for assembly and disassembly.

[0071] One end of the spray pipe 2 is detachably connected to the mounting plate 6 via the third connection structure 8, and the other end of the spray pipe 2 is detachably connected to the bottom plate 11 via the fourth connection structure 9, and the other end of the spray pipe 2 is connected to the liquid inlet. Figure 7 As shown, the third connecting structure 8 is a socket provided on the mounting plate 6, into which one end of the spray pipe 2 is inserted. The fourth connecting structure 9 is a quick-release connector. In one embodiment of this embodiment, the female connector 92 of the fourth connecting structure 9 is fixedly connected to the other end of the spray pipe 2, and the male connector 91 of the fourth connecting structure 9 is fixedly connected to the bottom plate 11. In addition, a return port is formed through the bottom plate 11, which connects to the cleaning area 101 and the external liquid collection device, so that the external liquid collection device can recycle and reuse the cleaning liquid through the return port.

[0072] By providing the second connection structure 7, the third connection structure 8, the fourth connection structure 9, and the return port, the connection structures between the mounting plate 6 and the side panels 5, between the mounting plate 6 and the spray pipe 2, and between the spray pipe 2 and the bottom plate 11, as well as the structure of the bottom plate 11, are simplified, more convenient to use, and quicker to assemble and disassemble. This also ensures the structural connection stability of the entire cleaning tank. When manufacturing the cleaning tank, the side panels 5, mounting plate 6, spray pipe 2, and nozzle 4 are then installed on the bottom plate 11 and the base frame 12. At the same time, a hole is opened in the bottom plate 11 to form a return port, thereby enabling the cleaning of the battery cells and the recycling of waste liquid within the cleaning tank.

[0073] In this embodiment, Figure 1 As shown, a liquid blocking structure cover is provided in the cleaning area 101 to prevent the cleaning liquid sprayed from the spray port from spraying out of the cleaning area 101. Through the action of the liquid blocking structure, the interference and pollution of the cleaning liquid to other mechanisms during cleaning can be reduced, thereby improving the safety and reliability of the use of the cleaning tank.

[0074] Specifically, in this embodiment, the liquid blocking structure includes a first blocking member 31 and a second blocking member 32, wherein the first blocking member 31 blocks the entrance of the cleaning area 101 to prevent the cleaning liquid from splashing out from the entrance of the cleaning area 101, and the second blocking member 32 blocks the exit of the cleaning area 101 to prevent the cleaning liquid from splashing out from the exit of the cleaning area 101, so that the entrance and exit of the cleaning area 101 are blocked and covered respectively by the first blocking member 31 and the second blocking member 32 to ensure that the cleaning liquid does not leak.

[0075] The first blocking members 31 are one or more groups, and the corresponding entrance of the cleaning area 101 includes one or more sub-entrances, each sub-entrance is used for one or a group of battery cells to be cleaned to pass through; the second blocking members 32 are one or more groups, and the corresponding exit of the cleaning area 101 includes one or more sub-exits, each sub-exit is used for one or a group of cleaned battery cells to pass through.

[0076] It should be noted that the number of second blocking members 32 can be equal to or greater than the number of first blocking members 31, as long as the battery cells entering the cleaning area 101 through the first blocking members 31 can respectively exit the cleaning area 101 through the corresponding second blocking members 32. In one implementation of this embodiment, multiple sets of first blocking members 31 and second blocking members 32 are provided, and the multiple sets of first blocking members 31 and second blocking members 32 are all arranged in parallel along the Y-axis direction, so that the cleaning tank can clean a group of multiple battery cells simultaneously, thereby improving the cleaning efficiency of the cleaning tank.

[0077] Specifically, one implementation method of this embodiment is to refer to Figure 9 As shown, the first blocking member 31 includes two first fixed blocks 311 and two first brushes 312. One first brush 312 is connected to one first fixed block 311. The first fixed block 311 is fixedly arranged. The two first brushes 312 on the two first fixed blocks 311 are arranged opposite to each other. The two first brushes 312 can be separated to form a first gap connected to the sub-entrance, or can be fitted and connected to seal the entrance of the cleaning area 101.

[0078] Furthermore, in this embodiment, the first fixing block 311 is extended along the arrow Z direction, and the rear side of the first fixing block 311 is fixedly connected to a grid bar 51 near the entrance of the cleaning area 101. The first fixing block 311 is connected to the grid bar 51 in a one-to-one correspondence. Therefore, in this embodiment, more than two grid bars 51 are provided on one side plate 5. In order to ensure that the multiple grid holes 501 on the side plate 5 can be sealed and covered by the two first brushes 312 arranged opposite to each other, Figure 9 As shown, a first brush 312 is provided on each of the two opposite sides of the first fixing block 311 .

[0079] Continue to refer Figure 9 As shown, taking the cleaning of a battery cell as an example, when the first blocking member 31 provided in this embodiment is in use, in the initial state, the two oppositely disposed first brushes 312 are in close contact with each other and seal the entrance to the cleaning area 101. When the battery cell moves in the direction of arrow X and squeezes the two oppositely disposed first brushes 312, the two first brushes 312 undergo elastic deformation, gradually separating to form a first gap for the battery cell to pass through. The first gap is connected to the grid hole 501, allowing the battery cell to continue to pass through the grid hole 501 and the avoidance space 121 into the cleaning area 101. After the entire battery cell has passed through the first gap, the two first brushes 312 return to their initial state and reset to continue to be in close contact. In this way, when cleaning the battery cell, the first brushes 312 can achieve the purpose of isolating the cleaning liquid from other external structures of the cleaning area 101.

[0080] Of course, bristles may not be provided in some areas on the first brush 312 to form a channel for the battery cells to pass through. This can also achieve the purpose of preventing the cleaning liquid from splashing out from the sub-inlet and ensuring that the battery cells safely enter the cleaning area 101.

[0081] It should be noted that in other implementations of this embodiment, when the brush structure of the first blocking member 31 is replaced with a film, tape, or flexible plastic sheet, the same technical effect as the brush structure can be achieved by providing openings in the film, tape, or flexible plastic sheet to form a channel for the battery cells to pass through. Therefore, in the various embodiments described above, as long as a channel for the battery cells to pass through can be provided or formed on the first blocking member 31, they are all within the scope of protection of this utility model.

[0082] Next, the second blocking member 32 is specifically introduced. One implementation method of this embodiment is to combine Figure 10 、 Figure 11 As shown, the second blocking member 32 includes two second fixed blocks 321 and two second brushes 322. One second brush 322 is connected to one second fixed block 321. The second fixed block 321 is fixedly arranged. The two second brushes 322 on the two second fixed blocks 321 are arranged opposite to each other. The two second brushes 322 can be separated to form a second gap connected to the sub-outlet, or can be fitted and connected to seal the outlet of the cleaning area 101.

[0083] Furthermore, in this embodiment, the battery cell completes the movement process of entering and leaving the cleaning area 101 along the direction of arrow X, that is, along the direction of arrow X, the first blocking member 31 and the second blocking member 32 are spaced apart at both ends of the cleaning area 101. Based on this, the second fixed block 321 is extended along the direction of arrow Z and is fixedly connected to the side plate 5 near the exit of the cleaning area 101, and a second fixed block 321 is fixedly connected to the inner side of a grid bar 51, and the second fixed block 321 is connected to the grid bar 51 in a one-to-one correspondence. Therefore, in this embodiment, more than two grid bars 51 are also provided on the other side plate 5. In order to ensure that the multiple grid holes 501 on the side plate 5 can be sealed and covered by the two second brushes 322 arranged opposite to each other, refer to Figure 11 As shown, a second brush 322 is provided on each of the two opposite sides of the second fixing block 321 .

[0084] For example, when the second blocking member 32 is used, in the initial state, the two second brushes 322 arranged opposite each other are connected and seal the outlet of the cleaning area 101. When the battery cell in the cleaning area 101 is cleaned, the battery cell continues to move in the direction of arrow X. After the battery cell passes through the avoidance space 121 on the base frame 12 and the grid hole 501 on the side plate 5 in sequence, the two second brushes 322 arranged opposite each other are squeezed, causing the two second brushes 322 to elastically deform. The two brushes 322 gradually separate to form a second gap for the battery cell to pass through, so that the battery cell can pass through the second gap and leave the cleaning area 101. After the entire battery cell passes through the second gap, the two second brushes 322 return to their initial state and reset to continue to be connected. In this way, when cleaning the next battery cell entering the cleaning area 101, the second brushes 322 can achieve the purpose of isolating the cleaning liquid from other external structures of the cleaning area 101.

[0085] Through the arrangement of the above-mentioned first blocking member 31 and the second blocking member 32, the cleaning tank can automatically open or close the entrance and exit of the cleaning area 101 without manual intervention, thereby reducing the labor intensity of the staff. At the same time, the first brush 312 and the second brush 322 have excellent water-blocking effects, which can ensure that the cleaning liquid cannot overflow the cleaning area 101.

[0086] More specifically, if Figure 1 As shown, the opening of the cleaning area 101 also includes a side opening and a top opening. The liquid blocking structure provided in this embodiment also includes a third blocking member 33 for blocking the side opening to prevent the cleaning liquid from splashing out of the side opening, and a fourth blocking member 34 for blocking the top opening to prevent the cleaning liquid from splashing out of the top opening.

[0087] In this embodiment, a third barrier 33 is provided on each side of the cleaning area 101 along the direction indicated by arrow Y. The ends of the third barrier 33 along the direction indicated by arrow X are connected to the first barrier 31 and the second barrier 32, respectively, thereby sealing the two sides of the cleaning area 101. Along the direction indicated by arrow Z, fourth barriers 34 are spaced apart on the bottom plate 11 to seal the top of the cleaning area 101. Thus, the first barrier 31, the second barrier 32, the third barrier 33, and the fourth barrier 34 form a cover that covers the cleaning area 101. This shielding function isolates the cleaning area 101 from other components within the cleaning tank at the top and sides, ensuring a reliable seal for the cleaning area 101.

[0088] It should be noted that, in other embodiments, the third blocking member 33 is formed as a side plate of the trough body 1, and the fourth blocking member 34 is not provided, that is, the trough body 1 is not provided with a top plate, so that the trough body 1 has three openings, namely, the entrance to the cleaning area 101, the outlet of the cleaning area 101 and the top opening, so that the battery cells can leave the cleaning area 101 from either the outlet of the cleaning area 101 or the top opening.

[0089] The fourth blocking members 34 may be provided in one or more groups, with the specific number of groups being determined by the length of the cleaning area 101 along the Y-axis. In this embodiment, since multiple groups of first and second blocking members 31, 32 are provided along the Y-axis, multiple groups of fourth blocking members 34 are also provided to ensure the sealing of the top opening of the cleaning area 101. Accordingly, the top opening includes multiple top sub-openings, and the multiple top sub-openings are provided corresponding to the multiple groups of fourth blocking members 34.

[0090] Specifically, in this embodiment, referring to Figure 11As shown, each group of fourth blocking members 34 includes two third fixed blocks 341 and two third brushes 342, one third brush 342 is connected to one third fixed block 341, the third fixed block 341 is fixedly set, and the two third brushes 342 on the two third fixed blocks 341 are relatively set and sealed to close the corresponding top sub-opening. The blocking effect of the third brush 342 prevents the cleaning liquid from splashing out of the top of the cleaning area 101. In addition, because the water-guiding effect of the brush is stronger than that of the baffle, the cleaning liquid splashed onto the third brush 342 can flow along the third brush 342 to the first brush 312 or the second brush 322, and then flow along the first brush 312 or the second brush 322 to the bottom plate 11 of the tank body 1, thereby preventing the cleaning liquid from being retained on the first brush 312, the second brush 322, and the third brush 342, further preventing leakage of the cleaning liquid, and saving the cost of cleaning liquid by collecting the cleaning liquid on the bottom plate 11. Furthermore, in this embodiment, two fourth blocking members 34 are stacked above each grid bar 51 in the vertical direction to further improve the water-blocking effect.

[0091] Similarly, the third brush 342 can also be replaced by a flexible plastic sheet, tape or film to achieve the same technical effect as the above-mentioned brush structure.

[0092] It should be noted that, since the side plate 5 includes a plurality of bars 51, in order to achieve the purpose of blocking the top opening of the cleaning area 101 by the third brush 342, the present embodiment is provided with a plurality of mounting plates 6, both ends of the mounting plates 6 are detachably connected to the bars 51 by a mortise and tenon structure. Figure 7 As shown, a tenon 71 is provided at the top of the grid plate, and a mortise 72 is provided at each end of the mounting plate 6. The tenon 71 is inserted into each mortise 72, thereby completing the fixation of one mounting plate 6. After multiple mounting plates 6 are fixed in the above manner, the third fixing block 341 is fixedly connected to the inner side of the mounting plate 6. The third fixing block 341 is provided in a one-to-one correspondence with the mounting plate 6. Similar to the first blocking member 31 and the second blocking member 32, a third brush 342 is also provided on both sides of the third fixing block 341. This allows the top opening of the cleaning area 101 to be blocked by multiple pairs of oppositely disposed third brushes 342, achieving a good blocking effect and significantly reducing leakage of the cleaning liquid.

[0093] Optionally, in this embodiment, taking the first blocking member 31 as an example, refer to Figure 12As shown, a slide groove 301 is provided on the first fixed block 311, and a slider 302 is provided on the first brush 312. The slider 302 of the first brush 312 is slidably clamped in the slide groove 301 of the first fixed block 311, so that the first brush 312 can be firmly installed on the first fixed block 311. When the first brush 312 needs to be replaced or maintained, it is only necessary to pull the first brush 312 out of the first fixed block 311, thereby shortening the disassembly and assembly time of the first brush 312 and improving the maintenance convenience.

[0094] It should be noted that, in this embodiment, similar to the first blocking member 31, the second fixing block 321 and the third fixing block 341 are also provided with the aforementioned sliding groove 301. Accordingly, the second brush 322 and the third brush 342 are also provided with the aforementioned slider 302, thereby facilitating maintenance of the second brush 322 and the third brush 342. During the manufacture of the cleaning tank, the liquid retaining structure is finally installed on the aforementioned bottom plate 11, mounting plate 6, and side plates 5 to seal and enclose the cleaning area 101 of the cleaning tank and prevent leakage of the cleaning liquid. Thus, the manufacture of the cleaning tank is completed.

[0095] This embodiment further provides a photovoltaic device including the aforementioned cleaning tank. Because the cleaning tank can be provided in the cleaning area 101 via a liquid-blocking structure to prevent the cleaning liquid from splashing out of the cleaning area 101, this solves the technical problem in related arts where the cleaning method easily interferes with the normal operation of other mechanisms outside the cleaning area 101. This makes the photovoltaic device including the cleaning tank safer to use, has a longer service life, and more stable operation.
