Description

Technical Field

[0001] The utility model relates to the field of solar cell production, in particular to a cooling device for a blanking end of a solar cell. Background Art

[0002] Solar cell texturing is an important step in solar cell production. After the silicon wafer undergoes the texturing process, the dirt and cutting damage layer on the surface of the silicon wafer can be effectively removed to clean the silicon wafer. In addition, by using low-concentration alkali to prepare a textured velvet surface on the anisotropy of different crystal planes of the silicon wafer, the light trapping effect is used to increase the absorption of light and the surface area of ​​the silicon wafer, thereby achieving the purpose of improving the efficiency of the cell.

[0003] Currently, certain defects have been found in the solar cell texturing production process. For example, in order to effectively clean the silicon wafers during the texturing process, chemical etching using chemicals and additives at a relatively high temperature is involved. After the process is completed, the wafers must be dried at a relatively high temperature. The uncooled wafers are then directly output to the discharge port to await cooling in subsequent processes. However, when an operator is required to track the experiment or when the wafers enter the rejection end of the discharge track due to problems such as waiting for liquid, missing wafers, or abnormal appearance, the baskets must be manually transported. Since the rejection end is usually not equipped with a corresponding cooling device, the baskets must be allowed to cool naturally before they can be transported, resulting in low production efficiency. Furthermore, when the operator directly handles the wafers, they may be burned. Utility Model Content

[0035] The following is a more detailed description of the solar cell texturing feed end cooling device of the present invention, with reference to a schematic diagram. This diagram illustrates a preferred embodiment of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0036] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0037] Example 1

[0038] like Figures 1 to 2 As shown, an embodiment of the present utility model proposes a cooling device for the blanking end of solar cell texturing, which includes a support platform 1, a blowing pipe assembly 2 and a gas conveying component 3.

[0039] Among them, the support table 1 has a cavity 11 built in, and the upper surface of the cavity 11 is provided with an opening connected to the outside world. A mesh support member 4 is embedded in the opening, that is, the flower basket loaded with silicon wafers is supported by the mesh support member 4, and gas can be blown out from the mesh support member 4 to quickly cool the flower basket, making it convenient for operators to quickly pick up and carry it, thereby improving production speed and correspondingly increasing the safety factor.

[0040] Specifically, one end of the blowing pipe assembly 2 is placed in the cavity 11 and faces the mesh support 4. The gas conveying member 3 is disposed on the blowing pipe assembly 2. That is, external air is output from the blowing pipe assembly 2 via the gas conveying member 3. Since one end of the blowing pipe assembly 2 faces the mesh support 4, the air can cool the flower baskets on the mesh support 4.

[0041] The device is provided with a support platform 1, a blowing pipe assembly 2 and a gas conveying member 3, and a cavity 11 with an opening on the upper surface is provided inside the support platform 1, and a mesh support member 4 is embedded in the opening to be able to carry the flower basket discharged from the rejection end, and with the help of the blowing pipe assembly 2 and the gas conveying member 3, the gas is ejected from the mesh support member 4, thereby effectively cooling the flower basket located on the mesh support member 4, making it convenient for operators to track experiments and quickly transport flower baskets loaded with abnormal silicon wafers, thereby achieving the purpose of improving production speed and safety factor.

[0042] In a further embodiment, in order to improve the cooling effect, the blowing pipe assembly 2 is further limited.

[0043] Specifically, the blowing pipe assembly 2 includes a gas pipeline 21 and a distributor 22 .

[0044] One end of the gas pipe 21 is suspended and fixed inside the cavity 11 so that the end of the gas pipe 21 can be directed toward the mesh support 4 to ensure the effect of air blowing and cooling.

[0045] The distributor 22 is arranged at the end of the gas pipeline 21 and is connected to the gas pipeline 21, so that the gas discharged from the gas pipeline 21 enters the distributor 22, and then the gas can be evenly distributed on the periphery of the flower basket during subsequent gas discharge, so as to better dissipate heat from the surface of the flower basket.

[0046] The distributor 22 includes a sleeve 221 and a plurality of sleeves 222 communicating with the sleeve 221 .

[0047] The plurality of sleeves 222 are equidistantly arranged in an annular shape on the outer wall of the sleeve 221, and a plurality of air outlet holes are opened on the upper surface, so that the gas can be blown out in a wrapped shape when discharged, thereby increasing the contact area between the gas and the outer surface of the flower basket, thereby better improving the cooling effect.

[0048] In addition, in this embodiment, the sleeve 221 is rotatably connected to the outer wall of the end of the gas pipe 21, so that the sleeve 221 can rotate, thereby generating wind force to be output to the flower basket, completing the secondary cooling operation of the flower basket, and achieving the purpose of further improving the cooling effect.

[0049] Furthermore, a sealing ring (not shown in the figure) is provided between the sleeve 221 and the gas pipe 21 to prevent gas leakage and affect the cooling effect on the flower basket.

[0050] In other embodiments, the sleeve 221 is further limited to better control the relative rotation of the sleeve 221 and the gas pipe 21 to generate wind force, thereby improving the cooling effect on the flower basket.

[0051] Specifically, a first bevel gear 5 is provided on the outer wall of the sleeve 221, a motor is provided inside the support platform 1, and a second bevel gear 6 engaged with the first bevel gear 5 is installed at the output end of the motor. The motor is driven to operate so that the rotation of the sleeve 221 is controlled under the action of the second bevel gear 6 and the first bevel gear 5.

[0052] In addition, it should be particularly noted that, in this embodiment, the other end of the gas pipe 21 passes through the support platform 1 and extends to the outside of the support platform 1 .

[0053] The gas conveying member 3 includes a pump body 31 and a control valve 32. The pump body 31 and the control valve 32 are both arranged on the gas pipeline 21 exposed to the outside of the cavity 11, so as to provide gas conveying power and control the gas flow rate respectively, that is, to extract external gas through the pump body 31 and output the gas from the gas pipeline 21 to complete the cooling operation.

[0054] Example 2

[0055] like Figure 3As shown, the difference between this embodiment and the first embodiment is that another gas conveying component 3 is proposed to replace the power equipment (such as the pump body 31), thereby achieving the purpose of reducing the use cost.

[0056] Specifically, the gas pipeline 21 is placed in the cavity 11 , and the outer wall of the gas pipeline 21 and the gas outlet are respectively provided with a one-way gas inlet valve and a one-way gas outlet valve.

[0057] The gas conveying member 3 includes a rotating disk 33 , a piston push rod 34 and a hinge rod 35 .

[0058] The rotating disk 33 is rotatably mounted on the inner wall of the cavity 11 and is synchronously connected to the second bevel gear 6 , so that when the motor is driven, the second bevel gear 6 and the rotating disk 33 rotate synchronously.

[0059] The piston push rod 34 is slidably installed in the gas pipeline 21. One end of the hinged rod 35 is hinged to the edge of the rotating disk 33, and the other end is hinged to the piston push rod 34 to form a crank slider mechanism.

[0060] When the rotating disk 33 rotates, the hinged rod 35 is controlled to deflect, so that the piston push rod 34 slides back and forth in the gas pipe 21. Accordingly, gas can be intermittently ejected from the one-way gas outlet valve to cool the gas. Moreover, only the same motor is needed to complete the gas delivery of the gas pipe 21 and the relative rotation of the sleeve 221 and the gas pipe 21, thereby effectively reducing the cost of use.

[0061] It should be noted that the rotating disk 33 is connected to the output end of the motor via a synchronous belt 7 .

[0062] In a further embodiment, the mesh support member 4 is configured as a wire mesh.

[0063] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
