Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber carrier boards, and in particular to a photovoltaic carrier board suitable for carbon fiber materials. Background Art

[0002] In the production process of solar cells, silicon wafers are placed on carriers, which are carried into the solar cell coating equipment and undergo process reactions in the equipment. Since the conveyor line span of the process equipment is relatively large, the carrier must be large in size and light in weight, while also having good rigidity. In summary, carbon fiber materials are very suitable, and carbon fiber boards have excellent properties such as high strength, low density, and high temperature resistance.

[0003] At present, a large carbon fiber sheet is used to process the carrier body, which is the part used to carry the silicon wafer. Due to its insufficient structural strength, a structure is added around or at the bottom of the carrier body to increase the structural strength. However, the carbon fiber material has a very high hardness, which makes traditional cutting tools easy to wear when processing carbon fiber. The rapid wear of the tool not only increases the processing cost, but also affects the processing accuracy and surface quality. This requires the structure of the carrier to have a high structural strength and be streamlined in areas that require fine processing. Utility Model Content

[0004] The utility model provides a photovoltaic carrier plate suitable for carbon fiber material, which can effectively solve the above problems.

[0005] The utility model is achieved in this way:

[0006] A photovoltaic carrier plate suitable for carbon fiber material, comprising:

[0007] A carrier body made of carbon fiber material, provided with a plurality of grooves for placing silicon wafers;

[0008] The frame includes a frame and a plurality of longitudinal bars and transverse bars arranged in the frame, all of which are made of carbon fiber. The upper end surface of the frame is provided with a plurality of leveling bosses, and the upper end surfaces of the leveling bosses abut against the lower end surface of the carrier body;

[0009] A T-shaped latch passes through the carrier body and is connected to the frame to fix the carrier body on the frame.

[0010] As a further improvement, right-angle connectors are provided between the longitudinal rod and the cross rod and the frame for fixation, the longitudinal rod passes through the cross rod, and a right-angle connector is further provided between the longitudinal rod and the cross rod, and the upper end surfaces of the frame and the cross rod are provided with the leveling boss.

[0011] As a further improvement, the frame is composed of two horizontal beams and two longitudinal beams, the leveling boss is provided on the horizontal beam, and a blind hole is provided in the middle of the leveling boss, the T-shaped pin includes a vertical part and a horizontal part, a through hole is provided on the vertical part, the T-shaped pin is inserted into the blind hole, and the bolt passes through the horizontal beam and the through hole to fix it.

[0012] As a further improvement, the upper end surface of the longitudinal rod is also provided with the leveling boss, and the side surface of the longitudinal rod is embedded with a square nut below the leveling boss. The tightening bolt passes through the carrier body and is inserted into the longitudinal rod to connect with the square nut.

[0013] As a further improvement, an L-shaped hanger is provided on the side of the cross bar, one end of the L-shaped hanger is fixed to the cross bar and the other end is inserted into the through hole.

[0014] As a further improvement, a plurality of exhaust holes are provided on the bottom surface of the groove.

[0015] As a further improvement, the carrier plate body is composed of four small plates.

[0016] The beneficial effects of the utility model are:

[0017] High structural strength: A frame is provided on the lower end of the carrier body. The frame includes a thicker frame and internal longitudinal and transverse bars, all made of carbon fiber. This greatly improves the overall structural strength of the carrier. This design can better adapt to the requirements of large-span conveyor lines of process equipment, ensuring that silicon wafers will not be deformed or damaged when being carried.

[0018] Reduce processing difficulty and cost. Due to the high hardness of carbon fiber materials, traditional processing tools are easy to wear, the processing cost is high and affects the processing accuracy and surface quality. After the improvement, several leveling bosses are set on the upper end face of the frame. Only the upper end face of the leveling boss needs to be fine-machined, which greatly reduces the area that needs to be processed. This not only reduces the degree of tool wear and reduces processing costs, but also improves processing accuracy and avoids problems such as surface unevenness and scratches caused by large-area processing.

[0019] It is easy to assemble and fix. The carrier body is fixed to the frame with T-shaped pins. The design of T-shaped pins makes the assembly process simpler and faster, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Reference Figure 1-6 As shown, a photovoltaic carrier suitable for carbon fiber material comprises: a carrier body 1 made of carbon fiber material, a plurality of grooves 11 are arranged in an array on the carrier body 1, and silicon wafers are placed in the grooves 11 when they need to be coated; in order to improve the structural strength of the carrier body 1, a frame 2 is further provided on the lower end face of the carrier body 1, the frame 2 comprises a frame 21 with a thicker cross section and a plurality of longitudinal rods 23 and transverse rods 22 arranged in the frame 21, the longitudinal rods 23 and transverse rods 22 can improve the overall structural strength of the frame 2, and all three are made of carbon fiber material, a plurality of leveling bosses 5 are provided on the upper end face of the frame 2, and the upper end face of the leveling boss 5 abuts against the lower end face of the carrier body 1. It should be noted that the carbon fiber material has a very high hardness, which makes traditional cutting tools easy to wear when processing carbon fiber. The rapid wear of the tool not only increases the processing cost, It will also affect the processing accuracy and surface quality. When the carrier body 1 and the frame 2 are assembled, the surface flatness between the two has certain requirements, and there should be no ups and downs to ensure the flatness of the surface of the carrier body 1. However, when trying to make one side of a whole carbon fiber material into a flat surface, the wear of the tool may cause unevenness, scratches and other problems on the processed surface. Therefore, many leveling bosses 5 are provided on the upper end face of the frame 2. During processing, only the upper end face of the leveling boss 5 needs to be fine-machined, thereby reducing the area to be processed, and in order to further improve the flatness after assembly, the lower end face of the carrier body 1 and the contact place with the leveling boss 5 can be locally fine-machined; a number of T-shaped pins 3, the T-shaped pins 3 pass through the carrier body 1 and are connected to the frame 2 to fix the carrier body 1 on the frame 2, and the T-shaped pins 3 are also made of carbon fiber material.

[0034] Specifically, in order to improve the structural strength of the frame 2, right-angle connectors are provided between the longitudinal rod 23 and the cross rod 22 and the frame 21 for fixation. The longitudinal rod 23 passes through the cross rod 22, and a right-angle connector is also provided between the longitudinal rod 23 and the cross rod 22. Leveling bosses 5 are provided on the upper end surfaces of the frame 21 and the cross rod 22.

[0035] Specifically, in order to facilitate the fixation of the carrier body 1 and the frame 21, the frame 21 is composed of three cross beams 211 and two longitudinal beams 212. Usually, the cross section of the frame 21 is larger. To facilitate fixation, a leveling boss 5 is provided on the cross beam 211, and a blind hole is provided in the middle of the leveling boss 5. The T-shaped pin 3 includes a vertical portion and a horizontal portion, and a through hole is provided on the vertical portion. The T-shaped pin 3 is inserted into the blind hole, and the bolt passes through the cross beam 211 and the through hole to fix it.

[0036] Specifically, in order to improve the fit between the carrier body 1 and the frame 2, a leveling boss 5 is also provided on the upper end surface of the longitudinal rod 23, and a slot is provided on the side of the longitudinal rod 23. The slot is located below the leveling boss 5, and a square nut 6 is embedded in the slot. The clamping bolt 4 passes through the carrier body 1 and is inserted into the longitudinal rod 23 and connected with the square nut 6 to press the carrier body 1 onto the frame 2. It should be noted that the clamping bolt 4 is only used to fix the longitudinal rod 23 in order to avoid uneven pressure when using multilateral clamping, which may cause the carrier body 1 to twist and deform.

[0037] Specifically, in order to facilitate the fixation of the carrier body 1 and the cross bar 22, an L-shaped hanger 7 is provided on the side of the cross bar 22. During assembly, one end of the L hanger 7 is fixed to the side of the cross bar 22 by bolts and nuts, and the other end is fitted between the carrier body 1 and the cross bar 22. The T-shaped pin 3 passes through the carrier body 1 and is inserted into the through hole.

[0038] Specifically, to facilitate the placement of the silicon wafer into / out of the groove 11, exhaust holes 111 are provided at the four corners of the bottom surface of the groove 11. When the silicon wafer is placed into the groove 11, a closed cavity is prevented from forming between the groove 11 and the silicon wafer, which is not conducive to stable placement. When the silicon wafer is taken out of the groove 11, a vacuum cavity is prevented from forming between the groove 11 and the silicon wafer, which prevents the silicon wafer from being sucked tightly into the groove 11 and making it difficult to take out.

[0039] Specifically, in order to reduce the manufacturing difficulty of the carrier body 1 and reduce the cost of parts, the carrier body 1 is composed of four small plates, which are easy to transport and disassemble. When one of the small plates has a problem, only a single small plate needs to be replaced.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
