Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solar energy, in particular to a wet-process basket device suitable for photovoltaic cell slices. Background Art
[0002] At present, with the vigorous development of the clean energy industry, photovoltaic cells as a green, renewable clean energy has gradually become a research hotspot. The industrial preparation technology of photovoltaic cells is becoming more and more diversified, and the preparation cost is becoming lower and lower. Among them, heterojunction cells are the solar cells with the highest market share due to their high energy conversion efficiency. In the production process of solar cells, the flower basket is responsible for carrying the original silicon wafers into the tank for the texturing process. In the texturing process, the silicon wafers are brought into each process tank for processing through the flower basket. As for the heterojunction cells after printing the ink, since the ink is not easy to solidify, the flower basket device needs to be used to carry the drying and curing process and the transmission process of the cell to ensure the batch production efficiency of the heterojunction cell.
[0003] In the related art, since the flower basket device for placing battery cells is placed vertically during the transfer process under the action of the robotic arm, the flower basket device in the related art is provided with limiting placement rods on the side end faces and the lower end faces, and the placement opening is not provided to limit and fix the battery cells. In actual applications, the inventors found that as the battery cells become thinner and the process requirements become higher and higher, the existing flower basket has fewer constraints, resulting in a large range of silicon wafer jumps due to the drive of the liquid during the process, which easily causes the silicon wafers to have missing corners, large broken edges and even fragments. For large-sized silicon wafers, stacking is easily produced, resulting in uneven surface texturing; and due to fewer constraints, the silicon wafers are tightly attached to the flower basket teeth due to the influence of gravity and liquid pressure during the process, and are not completely dried after cleaning, resulting in flower basket marks, which leads to an increase in the defective rate of battery cell production.

The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0043] Example
[0044] See also Figures 1 to 5 , this embodiment provides a wet-process basket device 10 suitable for photovoltaic cells, the basket device 10 includes: two support end plates 100, the two support end plates 100 are symmetrically arranged at intervals, it can be understood that the area of the support end plates 100 can be set according to the size of the photovoltaic cells to be installed, and there is no restriction here, a support bottom rod 200 and a support side rod 300, the two ends of the support bottom rod 200 and the support side rod 300 are respectively connected to the two support end plates 100, and are perpendicular to the support end plates 100, the support bottom rod 200, the support side rod 300 and the support end plates 100 form a receiving cavity with an opening on one side, and the receiving cavity is used to accommodate photovoltaic cells.
[0045] Specifically, such as Figure 1 and Figure 2 As shown, each support end plate 100 has a second mounting hole 120 along the length edge. Unlike the first mounting hole 110, the second mounting hole 120 is only opened on one length edge of the support end plate 100. The second mounting hole 120 is used to connect and fix the support bottom bar 200 to the support end plate 100. The second mounting holes 120 can be arranged in groups, such as 2, 3 or 4 per group. The number of second mounting holes 120 can be determined according to the number of support bottom bars 200 to be set.
[0046] Similarly, each support end plate 100 has a first mounting hole 110 along the width edge on its surface. The first mounting holes 110 can be arranged in groups, such as 2, 3 or 4 per group. The number of first mounting holes 110 arranged in the width direction on the left and right sides is equal and symmetrical. The first mounting holes 110 are used to connect and fix the support side rods 300 to the support end plates 100. Therefore, the number of first mounting holes 110 can be determined based on the number of support side rods 300 to be set.
[0047] It should be noted that the support bottom bar 200 and the support side bar 300 are arranged in a group. When the support bottom bar 200, the support side bar 300 are connected and fixed to the support end plate 100, the support bottom bar 200, the support side bar 300 and the support end plate 100 form a accommodating cavity with an opening on one side. The accommodating cavity is a rectangular accommodating cavity. The two groups of support bottom bars 200 are arranged in a mirror image and form three side surfaces of the rectangular accommodating cavity with a group of support side bars 300. The accommodating cavity is used to accommodate photovoltaic cells.
[0048] It should also be noted that the axes of all the supporting side rods 300 of each group or all the supporting bottom rods 200 of each group are located in the same virtual plane. The length and width of the rectangular accommodating cavity can be set according to actual needs. The side end surface of the supporting bottom rod 200 is provided with a plurality of bottom teeth 210 arranged at equal intervals along the length direction, and the side end surface of the supporting bottom rod 200 is provided with a plurality of side teeth 310 arranged at equal intervals along the length direction. The shape, size, spacing and number of the bottom teeth 210 and the side teeth 310 are equal, that is, from one end to the other of the supporting bottom rod 200 and the supporting side rod 300, each bottom tooth 210 has a corresponding side tooth 310 of the same height.
[0049] In this way, the support side rods 300 and the support bottom rods 200 can be arranged to stack photovoltaic cells and fix the photovoltaic cells between adjacent side teeth 310 and adjacent bottom teeth 210. When the photovoltaic cells are placed, their side end surfaces and bottom end surfaces can limit and fix the left and right sides and bottom ends of the cells.
[0050] In some embodiments, the interval between the side teeth 310 and the side teeth 310 can be 6.0mm, 6.3mm or 6.6mm, and the number of teeth of the entire supporting side rod 300 or the supporting bottom rod 200 can be 70, 80 or 90 intervals. This can effectively increase the space between the contact position of the bottom teeth of the basket and the solar cell, so that the chemical solution can fully flow into the space and effectively contact the photovoltaic cell, thereby improving the flow capacity of the chemical solution, allowing the chemical solution to fully and thoroughly react and clean the photovoltaic cell, reducing the residual amount of chemical solution, and thereby achieving the effect of reducing the proportion of blue tooth marks on photovoltaic cells, improving the color difference of the coating, improving the product yield of photovoltaic cells after texturing and cleaning, and improving the conversion efficiency of the cell.
[0051] Optional, such as Figure 3As shown, a snap-fit notch 140 is provided on the end face of each supporting end plate 100 close to the opening side of the rectangular accommodating cavity. The snap-fit notch 140 includes a notch end 141 and a notch bottom 142. It should be noted that the shape of the notch bottom 142 can be reasonably set according to the limiting pressure rod 400. The distance between the end faces on both sides of the notch end 141 is slightly smaller than the diameter of the notch bottom 142. In this way, the limiting pressure rod 400 is ensured to be inserted into the snap-fit notch 140 to achieve a snap-fit connection. Of course, the snap-fit notch 140 can also be other structures for achieving a snap-fit connection, for example, using elastic materials, which are not listed here one by one.
[0052] Optionally, two recessed portions 150 are provided on the end face of the supporting end plate 100, and the two recessed portions 150 are located on both sides of the engaging notch 140. The recessed portions 150 are used for the transfer of the flower basket device by the robotic arm. The specific structure is reasonably set according to the gripper of the robotic arm. An avoidance chamfer 160 is provided at one end of the supporting end plate 100 close to the recessed portion 150, and an avoidance notch 130 is provided at the chamfer between the first mounting hole 110 and the second mounting hole 120. In this way, by providing the recessed portions 150 on the two supporting end plates 100, it is convenient for the robotic arm to smoothly hook the flower basket device without changing the original position, and by providing the avoidance notch 130, it is convenient for the flower basket device to interfere with other devices and equipment during the transfer process.
[0053] In some embodiments, as Figure 4 and Figure 5 As shown, the limiting pressure rod 400, both ends of the limiting pressure rod 400 are embedded in the locking notch 140, and are snap-connected with the support end plate 100, and the limiting pressure rod 400 is used to press the photovoltaic cell sheet, wherein the limiting pressure rod 400 includes: a pressure rod body 410; a protrusion 430, which is arranged at both ends of the pressure rod body 410; a locking portion 440, which is arranged on the end face of the protrusion 430 away from the pressure rod body 410; wherein the locking portion 440 is connected with the locking notch 140 by interference fit, the pressure rod body 410, the protrusion 430 and the locking portion 440 are coaxially arranged, and the diameter length of the protrusion 430 is greater than the diameter length of the locking portion 440.
[0054] The locking portions 440 are configured in this way to be connected with the locking notches 140 by interference fit, so that the two ends of the limiting pressure rod 400 are connected with the support end plates 100 by snapping, which not only fixes the battery cells but also facilitates the placement and removal of the photovoltaic battery cells. Specifically, by providing the locking notches 140 and the limiting pressure rod 400 on the end faces of the two support end plates 100, the protrusions 430 and the locking portions 440 are provided at both ends of the limiting pressure rod 400, and at the same time, the limiting teeth 420 are provided at intervals on the side end faces of the limiting pressure rod 400. When multiple photovoltaic cells are placed After the cell is placed in the accommodating cavity; squeeze the limiting pressure rod 400 so that the locking parts 440 set at both ends are connected with the locking notch 140 by interference fit. At this time, the limiting pressure rod 400 is fixed with the two supporting end plates 100 by snap-fitting, and a photovoltaic cell is clamped between the two limiting teeth 420. In this way, each photovoltaic cell is fixed on all sides, effectively preventing the silicon wafer from floating due to the circulation of the liquid medicine when the flower basket is in the trough, thereby reducing the chipping of silicon wafers, large edge collapse and even fragments, and avoiding uneven texturing on the surface of silicon wafers, thereby improving the production yield of photovoltaic cells.
[0055] It should be noted that a plurality of limiting teeth 420 are arranged at equal intervals along the length direction on the side end surface of the pressure rod body 410, and the bottom teeth 210, the side teeth 310 and the limiting teeth 420 have the same shape, and the distances between two adjacent bottom teeth 210, two adjacent side teeth 310 and two adjacent limiting teeth 420 are equal, and the shapes of the bottom teeth 210, the side teeth 310 and the limiting teeth 420 include conical shapes or diamond shapes.
[0056] It should also be noted that the top surface of each limiting tooth 420 is formed by two inclined surfaces to form a supporting edge 421, thereby reducing the contact area between the limiting tooth 420 and the photovoltaic cell. The spacing of the limiting teeth 420 can be 6.0mm, 6.3mm or 6.6mm, and the number of teeth of the entire limiting pressure rod 400 can be 70, 80 or 90 intervals, which is the same as the number of teeth set on the supporting bottom rod 200 and the supporting side rod 300. The protrusion 430 and the locking portion 440 can be cylindrical, and a paddle 450 is set at one end of the protrusion 430. The setting of the paddle 450 facilitates the installation and disassembly of the limiting pressure rod 400.
[0057] It can be understood that the shape and density of the bottom teeth 210, side teeth 310 and limiting teeth 420 are the same. At the same time, taking the limiting teeth as an example, the top surface of the limiting teeth 420 is formed by two inclined surfaces to form a support edge 421, and the angle formed by the center axis of the rod can range from 30° to 90°. For example, the angle value is 30°, 45° or 60°. The specific selection can be made according to actual needs and is not limited here. Within this angle range, the contact area between the photovoltaic cell and the limiting teeth 420 can be further reduced to improve the yield and quality of the cell during electroplating or other production processes. The same is true for the bottom teeth 210 and the side teeth 310, which will not be elaborated here.
[0058] In this way, through the bottom teeth 210 set on the side end face of the supporting bottom rod 200, the side teeth 310 set on the side end face of the supporting side rod 300, and the limiting teeth 420 set on the side end face of the limiting pressure rod 400, the bottom teeth 210, the side teeth 310 and the limiting teeth 420 are the same shape, and the distances between two adjacent bottom teeth 210, side teeth 310 and limiting teeth 420 are equal, so that the photovoltaic cell can be fixed and limited more effectively. At the same time, the bottom teeth 210, the side teeth 310 and the limiting teeth 420 are shaped as a cone or a diamond, so as to reduce the contact area between the teeth and the photovoltaic cell, so that the chemical solution can fully flow into the space and effectively contact the cell, so that the chemical solution and the cell can fully and thoroughly react and clean, and the residual amount of chemical solution can be reduced, thereby achieving the effect of reducing the proportion of blue tooth marks on the cell, improving the color difference of the coating, and improving the product yield and cell conversion efficiency after texturing and cleaning of the cell.
