Description

Technical Field

[0001] The invention relates to a battery sheet processing device, in particular to a rack for drying batteries. Background Art

[0002] The preparation of the monocrystalline silicon velvet surface is to use the anisotropic etching of silicon to form millions of four-sided square cones, that is, pyramid structures, on each square centimeter of silicon surface. Before preparing the velvet, the silicon wafer must first undergo preliminary surface etching, using alkaline or acidic etching liquid to etch away about 20 to 25μm. After etching the velvet surface, general chemical cleaning is performed. Silicon wafers that have undergone surface preparation should not be stored in water for a long time to prevent contamination, and should be diffused and bonded as soon as possible.

[0003] Therefore, the photovoltaic cells (glass products) are cleaned and textured. After the texture is completed, they are dried with hot air (drying the residual moisture on the rack and the cells).

[0004] The existing solar cell drying rack (commonly known as PVDF wet basket in the industry) is as follows Figure 1 , Figure 2 , Figure 3 As shown,

[0005] Four parallel support rods are fixed on the two side panels, each support rod is provided with a row of protrusions, and a clamping groove is formed between adjacent protrusions. The downward protrusion of the upper left support rod and the upward protrusion of the lower left support rod are arranged oppositely, that is, the downward clamping groove of the upper left support rod and the upward clamping groove of the lower left support rod are arranged oppositely, and the downward protrusion of the upper right support rod and the upward protrusion of the lower right support rod are arranged oppositely, that is, the downward clamping groove of the upper right support rod and the upward clamping groove of the lower right support rod are arranged oppositely. The two relative clamping grooves 20 of the upper left support rod and the lower left support rod correspond to the relative two clamping grooves of the upper right support rod and the lower right support rod, and the clamping groove positions are corresponding, and are located on the same vertical surface, so that a battery cell can be inserted. In this way, the four support rods can be inserted into a row of battery cells, because the protrusions have a certain thickness, so there is a gap between adjacent battery cells. The two limiting rods fixed on the side panels are located on the same side of the four support rods, which play a role in limiting the side positions of the battery cells.

[0006] However, once the supporting rods of the cell rack are damaged, the cells will fall off and cannot be replaced. The entire rack has to be replaced, and once the size of the cells that can be dried changes, it is necessary to replace the rack with another size, which wastes a lot of costs. Summary of the invention

[0007] To solve the above problems, the present invention provides the following solutions:

[0008] A battery cell drying rack, wherein a parallel upper support rod and a lower support rod are fixed on the side plate, the upper support rod is provided with a row of protrusions downwardly, and clamping grooves are formed between the protrusions, and the lower support rod is provided with a row of protrusions upwardly, and clamping grooves are formed between the protrusions, and the clamping grooves of the upper support rod correspond to the clamping grooves of the lower support rod in position, and the side of the side plate fixed to the upper support rod or the lower support rod is a fixed surface, and a plurality of groups of parallel clamping holes are provided on the edge of the fixed surface, and each group of clamping holes includes a first clamping hole and a through groove opened from the first clamping hole to the edge of the side plate, and the first clamping hole and the through groove side wall are provided with a clamping groove outwardly so that the cross section of the through groove and the first clamping hole is T-shaped; clamping surfaces are provided at both ends of the upper support rod and the lower support rod, and the clamping surface has the same width as the clamping groove, and the clamping surface is aligned with the bottom end of the upper support rod or the lower support rod.

[0032] In order to make the purpose, technical scheme and advantages of the present application clearer, the present invention is further described in detail below in conjunction with embodiment. For a thorough understanding of the present invention, some specific details will be involved in the following description. And in the absence of these specific details, the invention can still be realized, that is, the skilled person in the art can more effectively introduce their work essence to other skilled persons in the field using these descriptions and statements herein. In addition, it should be noted that it should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the actual protection scope. All raw materials used in the following examples are commercially available products.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown:

[0034] The battery sheet drying rack of the present invention is similar to the prior art in most aspects of structure:

[0035] Four parallel support rods are fixed on the two side plates 1, each support rod is provided with a row of protrusions, and clamping grooves are formed between adjacent protrusions. The downward protrusion 21 of the upper left support rod 2 and the upward protrusion 31 of the lower left support rod 3 are arranged oppositely, that is, the downward clamping groove 20 of the upper left support rod 2 and the upward clamping groove 30 of the lower left support rod 3 are arranged oppositely, and the downward protrusion 41 of the upper right support rod 4 and the upward protrusion 51 of the lower right support rod 5 are arranged oppositely, that is, the downward clamping groove 40 of the upper right support rod 4 and the upward clamping groove 50 of the lower right support rod 5 are arranged oppositely. The two opposite clamping grooves 20 and 30 of the upper left support rod 2 and the lower left support rod 3 correspond to the two opposite clamping grooves 40 and 50 of the upper right support rod 4 and the lower right support rod 5, and are located on the same vertical surface, so that a battery cell 6 can be inserted. In this way, the four support rods can be inserted into a row of battery cells 6, because the protrusions have a certain thickness, so there is a gap between adjacent battery cells 6. The two limiting rods 7 fixed on the side plate 1 are located on the same side of the four supporting rods, and play a role in limiting the side positions of the battery cells 6 .

[0036] like Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 As shown,

[0037] Embodiment 1 of the present invention:

[0038] Four parallel support rods are fixed on the two side panels 1, and one side of the side panel 1 fixed to the upper support rod or the lower support rod is a fixed surface, and multiple groups of clamping holes are arranged in parallel on the edge of the fixed surface, and each group of clamping holes includes a first clamping hole 10, and a through groove 14 is arranged between the first clamping hole 10 and the edge of the side panel, and the side walls of the first clamping hole 10 and the through groove 14 are clamped with a clamping groove 9 outward; both ends of the upper support rod and the lower support rod are provided with a clamping surface 12, and the clamping surface 12 has the same width as the clamping groove 9, and a connecting line is formed between the clamping surface 12 and the bottom end of the upper support rod or the lower support rod. The connecting column 13 is connected, one end of the connecting column 13 and the other end of the clamping surface 12 are planes, and the diameter of the connecting column 13 is the same as the width of the through slot 14; the clamping surface 12 is inserted into the clamping slot 9 to connect the upper support rod or the lower support rod to the side plate 1, and the connecting column 13 and one end of the clamping surface 12 face the first clamping hole 10. After the upper support rod or the lower support rod is inserted into the first clamping hole 10, it slides toward the through slot until it is adjusted to a suitable position. After the adjustment is completed, the through slot 14 is embedded with an insert to fix the upper support rod or the lower support rod, and the first clamping hole 10 is blocked by a plug. When the size of the inserted battery cell is large and the distance between the upper support rod and the lower support rod is large, the support rod slides to the position of the through slot close to the edge of the side panel, the embedded block is inserted into the through slot 14 to fix the support rod, the plug covers the first clamping hole 10, and one end of the plug plane is against one end of the support rod plane; when the size of the inserted battery cell is small, the upper support rod and the lower support rod are located at the position of the through slot 14 close to the first clamping hole 10, first insert the embedded block into the through slot 14, and then insert the support rod into the first clamping hole 10, after sliding along the through slot 14 to a suitable position, the plug covers the first clamping hole 10, one end of the plug plane is against one end of the support rod plane, and the plug and the embedded block clamp and fix the support rod; screw holes are opened at the center of the plug and the corresponding bottom of the side panel, and when the support is fixed, the plastic screws are screwed into the screw holes to fix the plug.

[0039] The lowest outer surface axial line position of the lower right support rod 5 is taken as the bottom line 52, and a water droplet collecting strip 8 extends downward from the bottom line position of the lower right support rod 5. The water droplet collecting strip 8 is in a V shape, low in the middle and high on both sides, that is, it can be divided into two triangular left parts 81 and right parts 82, respectively. The distance from the lower edge line of the water droplet collecting strip 8 to the bottom line 52 of the lower support rod 5 is the height of the water droplet collecting strip 8, and the height of the left part 81 and the right part 82 are gradually increased from the end of the lower support rod 5 to the middle, and the height of the water droplet collecting strip 8 is the largest at point A, that is, the water droplet collecting strip 8 at point A is the lowest.

[0040] A V-shaped water droplet collecting strip extends downward from the bottom end line of the left lower support rod 3 of the same structure.

[0041] So, in actual use:

[0042] The drying rack and the battery cell 6 inserted in the clip groove are dried with hot air, and the water on the battery cell 6 will flow down to the lower left support rod 3 and the lower right support rod 5, and then flow along the surface of the lower right support rod 5 to the water drop collection bar 8, and flow to the lower edge of the water drop collection bar 8. Since the lower edge of the water drop collection bar 8 is inclined, the water will flow to the middle of the V-shaped water drop collection bar 8, and the water droplets will quickly gather at the middle of the V-shaped water drop collection bar 8, that is, the lowest point, that is, point A, and the weight of the water droplets will increase rapidly and fall, so that the water will fall off quickly, and the work efficiency will be improved. Similarly, the lowest point of the water drop collection bar of the lower left support rod 3 also plays a role in quickly collecting water droplets.

[0043] like Figure 7 Embodiment 2 of the present invention is shown:

[0044] Six V-shaped water droplet collecting strips 8' are arranged in a row and extend downward from the bottom line of the right lower support rod 5, so that water droplets gather and fall from the bottom tip A' of each water droplet collecting strip 8'. Similarly, six V-shaped water droplet collecting strips 8' are arranged in a row and extend downward from the bottom line of the left lower support rod 3.

[0045] like Figure 8 Embodiment 3 of the present invention is shown:

[0046] Six triangular water droplet collecting bars 8" are extended downward from the bottom line of the right lower support rod 5 and are arranged in a row, so that water droplets will gather and fall from the bottom tip A" of each water droplet collecting bar 8". Similarly, six triangular water droplet collecting bars 8" are extended downward from the bottom line of the left lower support rod 3 and are arranged in a row.

[0047] Of course, the purpose of the invention can also be achieved if there is only one triangular water droplet collecting strip under each support rod, and the water droplets will gather and fall at the lowest point of the water droplet collecting strip.

[0048] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation of the present invention.
