[0042] In the process of manufacturing the cell piece of the solar cell, texturing needs to be performed on the cell piece. The principle of texturing is to make the cell piece chemically corrode by contacting the cell piece with a chemical solution, so as to form a micron-level textured structure on the surface of the cell piece, thereby reducing light reflectivity and enhancing the ability of light absorption.
[0043] The existing texturing device includes a main texturing groove and a secondary texturing groove. The cell piece is located in the main texturing groove and chemically reacts with the chemical solution. In order to ensure that the cell piece can be fully contacted with the chemical solution, a circulating assembly is usually arranged in the texturing device to guide the chemical solution to circulate and flow in the main texturing groove and the secondary texturing groove. In the actual operation process, the pipeline in the circulating assembly which communicates with the main texturing groove is easily blocked by debris, which affects the normal circulation of the chemical solution and causes the texturing effect of the cell piece to be unable to meet the production requirements.
[0044] Please refer to Figure 1 , Figure 2 and Figure 8 , in order to alleviate the above problems, the present application provides a texturing device 1, which comprises a texturing assembly 10, a circulating assembly 20 and a water gun assembly 30. The texturing assembly 10 has a main texturing groove 122 and a secondary texturing groove 132. The secondary texturing groove 132 is arranged around the outer periphery of the main texturing groove 122. The circulating assembly 20 comprises a circulating pump 23, a circulating outlet pipe 21, a circulating inlet main pipe 24 and a plurality of circulating inlet branch pipes 25. The secondary texturing groove 132, the circulating outlet pipe 21, the circulating pump 23, the circulating inlet main pipe 24, each circulating inlet branch pipe 25 and the main texturing groove 122 are sequentially communicated, and the circulating inlet main pipe 24 and each circulating inlet branch pipe 25 are detachably connected. The water gun assembly 30 is configured to flush the circulating inlet branch pipe 25 when the circulating inlet main pipe 24 and the circulating inlet branch pipe 25 are detached.
[0045] Specifically, the main texturing groove 122 provides a place for the cell piece to be textured, and the main texturing groove 122 and the secondary texturing groove 132 both contain the chemical solution. The openings of the main texturing groove 122 and the secondary texturing groove 132 are both arranged upward.
[0046] As an example, the circulating inlet branch pipe 25 and the circulating inlet main pipe 24 can be detachably connected by screwing.
[0047] In actual operation, the circulating pump 23 is started, and the etching solution in the etching auxiliary groove 132 flows into the etching main groove 122 through the circulating outlet pipe 21, the circulating pump 23, the circulating inlet main pipe 24 and the circulating inlet branch pipes 25, and then overflows from the groove opening of the etching main groove 122 to the etching auxiliary groove 132, to form the circulation of the etching solution. Through the design of the etching solution circulation, the etching solution can be in full contact with the battery piece, and the etching effect is good.
[0048] In the present application, the etching device 1 is provided with the water gun assembly 30, and the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detachably connected, so that when the circulating inlet branch pipes 25 are blocked by the fragments, the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detached, and then the circulating inlet branch pipes 25 are flushed by the water gun assembly 30. The fragments can be flushed away, and then the fragments can flow out from the opening of the end of the circulating inlet branch pipes 25 detached from the circulating inlet main pipe 24, thereby reducing the influence of the fragments on the etching solution circulation, and making the battery piece have a better etching effect.
[0049] In the present application, the etching device 1 is provided with the water gun assembly 30, and the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detachably connected, so that when the circulating inlet branch pipes 25 are blocked by the fragments, the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detached, and then the circulating inlet branch pipes 25 are flushed by the water gun assembly 30. The fragments can be flushed away, and then the fragments can flow out from the opening of the end of the circulating inlet branch pipes 25 detached from the circulating inlet main pipe 24, thereby reducing the influence of the fragments on the etching solution circulation, and making the battery piece have a better etching effect.
[0050] In the present application, the etching device 1 is provided with the water gun assembly 30, and the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detachably connected, so that when the circulating inlet branch pipes 25 are blocked by the fragments, the circulating inlet main pipe 24 and the circulating inlet branch pipes 25 are detached, and then the circulating inlet branch pipes 25 are flushed by the water gun assembly 30. The fragments can be flushed away, and then the fragments can flow out from the opening of the end of the circulating inlet branch pipes 25 detached from the circulating inlet main pipe 24, thereby reducing the influence of the fragments on the etching solution circulation, and making the battery piece have a better etching effect.
[0051] In some embodiments, the water gun assembly 30 can only include the water gun 32, and the water gun 32 can spray high-pressure water flow to ensure that the fragments can be flushed away.
[0052] In some embodiments, the water gun assembly 30 comprises a flushing pipe 31 and a water gun 32, the diameter of the flushing pipe 31 is smaller than that of the circulating liquid inlet branch pipe 25, the flushing pipe 31 is configured to extend into the circulating liquid inlet branch pipe 25 when the circulating liquid inlet main pipe 24 is detached from the circulating liquid inlet branch pipe 25, and the water gun 32 is in communication with the flushing pipe 31.
[0053] In actual operation, the flushing pipe 31 extends into the circulating liquid inlet branch pipe 25, and when the flushing pipe 31 cannot extend further due to the obstruction of the debris, the water gun 32 is opened, so that the high-pressure flushing water flow can directly reach the position of the debris through the flushing pipe 31, and the flushing effect is good.
[0054] In some embodiments, the flushing pipe 31 is a polyvinyl chloride pipe (PVC pipe). The polyvinyl chloride pipe has high strength and rigidity, can withstand large pressure and load, and has a long service life under the impact of high-pressure flushing water flow. In addition, the polyvinyl chloride pipe also has good chemical stability, and is not easily corroded and eroded by chemical solutions, which enables it to work normally in harsh environments such as acid-base environment and high temperature.
[0055] Please refer to Figures 1 to 7 In some embodiments, the texturing assembly 10 comprises a base body 11, a texturing body 12, a filter plate 13, and a plurality of partition plates 14, the texturing body 12 is sleeved in the base body 11, the inner wall of the texturing body 12 defines a texturing main groove 122, the filter plate 13 is arranged around the outer periphery of the texturing body 12, and the inner wall of the base body 11 and the outer wall of the texturing body 12 define a texturing auxiliary groove 132 and a liquid passing cavity 15, the liquid passing cavity 15 is located at the bottom side of the filter plate 13 away from the texturing auxiliary groove 132, all the partition plates 14 are located in the liquid passing cavity 15, and cooperatively separate the liquid passing cavity 15 into a main groove liquid passing cavity 151 and an auxiliary groove liquid passing cavity 152 which are independent of each other; a plurality of filter holes 131 are formed in the filter plate 13, the filter holes 131 are in communication between the texturing auxiliary groove 132 and the auxiliary groove liquid passing cavity 152, the circulating liquid outlet pipe 21 is in communication with the auxiliary groove liquid passing cavity 152; the circulating liquid inlet branch pipe 25 is in communication with the main groove liquid passing cavity 151, and a plurality of permeation holes 121 are formed in the bottom plate of the texturing body 12, the permeation holes 121 are in communication between the main groove liquid passing cavity 151 and the texturing main groove 122.
[0056] Among them, the plurality of filter holes 131 are uniformly distributed on the filter plate 13, and the plurality of permeation holes 121 are uniformly distributed on the bottom plate of the texturing body 12.
[0057] Specifically, the etching body 12 is sleeved in the base body 11, and the outer wall of the etching body 12 is spaced apart from the inner wall of the base body 11. The top surface of the filter plate 13 and the inner wall of the base body 11 and the outer wall of the etching body 12 define an etching auxiliary groove 132, and the bottom surface of the filter plate 13 and the inner wall of the base body 11 and the outer wall of the etching body 12 define a liquid passing cavity 15. All the partition plates 14 are located in the liquid passing cavity 15 and on the bottom side of the etching body 12. The inner wall surface of all the partition plates 14 surrounds to form a main groove liquid passing cavity 151, and the outer wall surface of all the partition plates 14 and the inner wall surface of the base body 11 define a auxiliary groove liquid passing cavity 152. In addition, all the partition plates 14 cooperate to support the etching body 12, so that the etching body 12 is stably installed and is not easy to deform.
[0058] When the liquid medicine circulates, the liquid medicine in the etching auxiliary groove 132 flows into the auxiliary groove liquid passing cavity 152 through the filter plate 13. The filter plate 13 has a filtering effect, and under the filtering effect of the filter plate 13, the debris can be retained in the etching auxiliary groove 132, so as to reduce the risk of blocking the circulating outlet pipe 21, the circulating liquid inlet main pipe 24 and the circulating liquid inlet branch pipe 25 due to the debris flowing into the circulating assembly 20.
[0059] Then, the liquid medicine enters the main groove liquid passing cavity 151 through the circulating outlet pipe 21, the circulating liquid inlet main pipe 24 and the circulating liquid inlet branch pipe 25 in turn, and then penetrates into the etching main groove 122 through the penetration hole 121 on the etching body 12.
[0060] Among them, since the aperture of the penetration hole 121 is small, the penetration hole 121 can also block the debris in the etching main groove 122, so that it is more difficult for the debris to enter the circulating liquid inlet branch pipe 25 through the penetration hole 121 and the main groove liquid passing cavity 151, thereby further reducing the risk of blocking the circulating liquid inlet branch pipe 25 by the debris.
[0061] Please refer to Figures 1 to 4 In some embodiments, the base body 11 protrudes from the top surface of the etching main groove 122 of the etching body 12. Therefore, in the height direction of the base body 11, the side wall of the base body 11 has a certain blocking effect on the liquid medicine, thereby reducing the risk of splashing of the liquid medicine and sputtering out of the base body 11.
[0062] In some embodiments, the setting height of the filter plate 13 is higher than the bottom plate of the etching body 12.
[0063] As the main groove 122 is the main place for texturing, in order to facilitate the placement of the battery piece and to reduce the space occupied by the texturing device 1, generally, the space where the main groove 122 is arranged is large, and the space where the auxiliary groove 132 is arranged is small. The design makes the width of the auxiliary groove 132 narrow. If the depth of the auxiliary groove 132 is also deep, the difficulty of cleaning the debris in the auxiliary groove 132 will be increased. By arranging the filter plate 13 with a height higher than the bottom plate of the texturing body 12, the depth of the auxiliary groove 132 is shallow, so as to facilitate the cleaning of the debris.
[0064] It can be understood that the width of the auxiliary groove 132 is the width of the filter plate 13. The filter plate 13 is arranged around the outer periphery of the texturing body 12. The width of the filter plate 13 is the distance between the inner surface (i.e. the surface facing the texturing body 12) and the outer surface (i.e. the surface away from the texturing body 12) of the same frame edge of the filter plate 13. For example, as shown in FIG. 13. Figure 4
[0065] Please refer to Figure 1 In some embodiments, the texturing device 1 further comprises a heater 40. The heater 40 is connected between the circulating liquid outlet pipe 21 and the circulating pump 23, and is used to heat the liquid medicine, so that the liquid medicine can react with the battery piece at a suitable temperature required for texturing. If the temperature of the liquid medicine is too low, the corrosion rate of the battery piece is too slow, and the texturing period is prolonged. Therefore, the heater 40 is arranged to heat the liquid medicine, which helps to improve the corrosion rate and further improve the texturing efficiency.
[0066] For example, the temperature of the heated liquid medicine can be in the range of 70-85℃.
[0067] In some embodiments, the circulating assembly 20 can further comprise a connecting pipe 22 connected between the heater 40 and the circulating pump 23, so that the heated liquid medicine can be pumped into the main groove 122 by the circulating pump 23.
[0068] The present application also provides a texturing system comprising the texturing device 1 according to any one of the above embodiments. The texturing system has the effects brought by any one of the above embodiments, and thus will not be repeated here.
[0069] In some embodiments, the texturing system further comprises an acid washing device, a slow lifting drying device and a drying device. The acid washing device is used to neutralize the residual alkali solution on the battery piece after texturing. The slow lifting dehydration device is used to clean and dehydrate the battery piece after acid washing, so as to reduce the drying marks. The drying device is used to dry the battery piece after dehydration.
[0070] The application also provides a solar cell manufacturing production line, which comprises the texturing system according to the above-mentioned embodiments. The solar cell manufacturing production line has the effects of any one of the above-mentioned embodiments, and thus will not be described here.
[0071] The above-mentioned texturing device 1, texturing system and solar cell manufacturing production line are provided with the water gun assembly 30 in the texturing device 1, and the circulating liquid inlet main pipe 24 and the circulating liquid inlet branch pipes 25 are detachably connected, so that when the circulating liquid inlet branch pipes are blocked by debris, the circulating liquid inlet main pipe 24 and the circulating liquid inlet branch pipes 25 are detached, and then the circulating liquid inlet branch pipes 25 are flushed by the water gun assembly 30, so that the debris is flushed away, and then the debris can flow out from the opening of the circulating liquid inlet branch pipes 25 at the end of the circulating liquid inlet main pipe 24, thereby reducing the influence of the debris on the circulation of the liquid medicine, and making the battery piece have a better texturing effect.
[0072] The technical features of the above-mentioned embodiments can be combined in any way. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
[0073] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
