Description

Technical Field

[0002] Silicon wafer cutting is a critical component of the solar photovoltaic cell manufacturing process, processing solid silicon ingots (monocrystalline or polycrystalline). A wire saw is first used to cut the ingot into square silicon blocks, which are then sliced ​​into very thin wafers. These wafers become the substrates for photovoltaic cells. The core of the wire saw is an ultra-fine, high-strength cutting wire, which, in conjunction with an abrasive slurry, performs the cutting action. Multiple wires are wound parallel to each other around a wire reel, forming a horizontal wire grid. As the wires move, nozzles continuously spray abrasive slurry containing suspended silicon carbide particles onto the wires. The abrasive slurry is driven by the wires to cut the silicon blocks.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 4 As shown, this embodiment provides a positioning jig for the production of photovoltaic modules, including: a connecting seat 1, a heat dissipation chamber 3 is fixedly connected to the bottom of the connecting seat 1, a silicon material 13 is fixedly connected to the bottom of the heat dissipation chamber 3, a cavity is provided in the heat dissipation chamber 3, a plurality of air inlets 4 are provided on the bottom surface of the heat dissipation chamber 3, and air outlets 5 are provided on the front and rear sides. A heat exchange tube 7 is fixedly installed in the cavity of the heat dissipation chamber 3, and both ends of the heat exchange tube 7 pass through the inner wall of the heat dissipation chamber 3 and extend to the outside of the heat dissipation chamber 3 and are connected to a cooling water tank 16. The cooling water tank 16 is fixed to the outside of the heat dissipation chamber 3, and a hair dryer 10 is provided above the cooling water tank 16.

[0026] The utility model is used on a cutting device for processing photovoltaic modules. The connecting seat 1 is connected to the lifting mechanism on the cutting device. When cutting the silicon material 13, the cutting wire mesh of the cutting device cuts from bottom to top, and the cutting wire mesh and the silicon material 13 continuously rub to generate heat. Therefore, the heat accumulated on the top of the silicon material 13 is relatively high. The heat on the top of the silicon material 13 can be transferred upward to the heat dissipation bin 3 through the air inlet 4, and part of the hot air is discharged through the air outlet 5; at the same time, cooling water is provided in the cooling water tank 16, and the cooling water circulates in the heat exchange tube 7. Therefore, the heat of the hot air in the heat dissipation bin 3 can also be heat exchanged with the cooling water in the heat exchange tube 7. The cooling water in the heat exchange tube 7 absorbs the heat and enters the cooling water tank 16. The hair dryer 10 can cool the cooling water, thereby achieving the purpose of continuously cooling the heat inside the heat dissipation bin 3. The present application efficiently replaces the heat inside the heat dissipation bin 3 through the flow of air in the heat dissipation bin 3 and the heat exchange between the cooling water circulating in the heat exchange tube 7 and the hot air, so that the heat in the heat dissipation bin 3 will not accumulate, and the purpose of efficiently dissipating the silicon material 13 at the bottom of the heat dissipation bin 3 can be achieved. The heat dissipation effect is good and the collapse of the upper end of the silicon material 13 can be effectively avoided.

[0027] Furthermore, the heat exchange tubes 7 are arranged in a serpentine shape in the heat dissipation chamber 3, which can increase the heat exchange area and speed up the heat exchange efficiency.

[0028] To further optimize the solution, a number of heat-conducting aluminum plates 6 are fixedly installed on the side of the heat dissipation chamber 3, and the heat-conducting aluminum plates 6 connect the inside of the heat dissipation chamber 3 with the outside.

[0029] The heat-conducting aluminum plate 6 has good thermal conductivity and can quickly discharge the heat of the hot air inside the heat dissipation chamber 3, further improving the cooling effect and efficiency.

[0030] To further optimize the solution, a water pump 8 is fixedly connected to the inner wall of the cooling water tank 16 , and the water pump 8 connects the interior of the cooling water tank 16 and the heat exchange pipe 7 .

[0031] The water pump 8 is used to circulate the cooling water in the cooling water tank 16 and the heat exchange tube 7, thereby achieving heat transfer and heat exchange of the heat in the heat dissipation chamber 3.

[0032] To further optimize the solution, a clamping mechanism 12 is symmetrically fixed to the left and right sides of the heat dissipation bin 3. The clamping mechanism 12 includes a support plate 1204. One end of the support plate 1204 is fixed to the outer side of the heat dissipation bin 3, and the other end is bent downward and threadedly connected to a threaded rod 1202. The end of the threaded rod 1202 close to the silicon material 13 is fixed to a clamping pad 1203, and the end away from the silicon material 13 is fixed to a turntable 1201.

[0033] The clamping mechanisms 12 on both sides can clamp and fix the silicon material 13 from both sides. During clamping, the threaded rod 1202 is moved on the support plate 1204 by rotating the turntable 1201, so that the clamping pad 1203 abuts against the silicon material 13 to clamp the silicon material 13. The clamping is convenient and fast.

[0034] According to a further optimized solution, a mortar guide plate 14 is bonded to the bottom surface of the silicon material 13 , and a plurality of cutting marking openings 15 are opened at the bottom of the mortar guide plate 14 .

[0035] The mortar guide plate 14 is sintered from mortar slurry, and the cutting marking port 15 is a uniformly opened groove, which can guide the cutting wire net for cutting, thereby improving the cutting accuracy; when cutting, the cutting wire net first cuts the mortar guide plate 14, and then cuts into the silicon material 13, thereby avoiding the cutting wire net directly cutting the silicon material 13 and causing slipping, thereby improving the cutting quality. Moreover, the raw material of the mortar guide plate 14 contains mortar raw material, and the mortar generated by cutting the mortar guide plate 14 enters the silicon material 13, which also helps in cutting.

[0036] To further optimize the solution, a connecting plate 11 is fixedly connected to the side of the cooling water tank 16 , and the connecting plate 11 is fixedly connected to the side of the heat dissipation chamber 3 .

[0037] To further optimize the solution, a mounting plate 9 is fixedly connected to the top of the cooling water tank 16, and a hair dryer 10 is fixedly connected to the mounting plate 9 to blow air toward the inside of the water tank.

[0038] According to a further optimized solution, a connecting groove 2 is provided on the top surface of the connecting seat 1 .

[0039] The connection groove 2 matches the shape of the lower end portion of the lifting mechanism of the cutting device, making it easy to connect with the cutting device.

[0040] How it works

[0041] When cutting the cooling water tank 16, the silicon material 13 is first placed under the heat dissipation chamber 3. By rotating the turntable 1201, the threaded rod 1202 and one end of the clamping pad 1203 can be driven to position the silicon material 13. The mortar guide plate 14 is bonded to the bottom of the silicon material 13. The cutting wire mesh is used to accurately cut the silicon material 13 along the cutting mark 15. The mortar powder generated by the mortar guide plate 14 helps to prevent slipping when cutting the silicon material 13. The heat generated during the cutting process will rise and enter the interior of the heat dissipation chamber 3 through the air inlet 4. When there is a large amount of hot air, part of the hot air will be discharged from the hot air outlet due to the influx of gas. A group of heat-conducting aluminum plates 6 can conduct the heat of the hot air inside it and discharge it. The hot air contacts the heat exchange tube 7. The cooling water inside the heat exchange tube 7 will absorb the heat in the hot air and send it into the cooling water tank 16. The hair dryer 10 can be used to cool the cooling water to achieve continuous cooling of the heat inside the heat dissipation chamber 3.
