Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing technology, and in particular to a transport device for solar cell strings. Background Technology

[0002] With the continuous development of photovoltaic technology, the solar cell industry has gradually gained attention and favor. The manufacturing process of solar panels involves connecting individual solar cells in series and parallel using solder ribbons to form solar cell strings. Multiple such solar cell strings are then connected in series and parallel to form cells. Finally, components such as backsheets, EVA panels, and glass plates are assembled onto the cells to complete the processing of the solar panel.

[0003] In actual manufacturing processes, due to the different coefficients of thermal expansion between solar cells and solder ribbons, some existing solar cell string handling devices lack heating functions. This can easily lead to pull-out of the solar cells and solder ribbons during the handling and transfer of solar cell strings, reducing work efficiency and affecting product performance. Furthermore, while some solar cell string handling devices do have heating functions, their heating carrier plates are often a single, integrated structure. Over time, this can deform, resulting in uneven contact surfaces and uneven heating of the solar cells.

[0004] Therefore, there is an urgent need to design a solar cell string handling device to solve the above technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a transport device for solar cell strings, which has a simple structure, controllable deformation of the carrier plate, and can improve the uniformity of heating of the solar cells.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0035] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figures 1-4As shown, this embodiment provides a solar cell string handling device, mainly including a support 100, a carrier plate 200, a heating component 300, and a suction cup assembly 400. Several carrier plates 200 are provided, and these carrier plates 200 are mounted on the support 100 by fasteners 220. A first preset gap 210 is provided between adjacent carrier plates 200, and the fasteners 220 are adjustable in height relative to the support 100. Several heating components 300 are provided, and at least one heating component 300 is provided on each carrier plate 200. The suction cup assembly 400 is partially embedded within the carrier plate 200 and is used to attract solar cells, so that the solar cells are in contact with the main plane 230 of the carrier plate 200.

[0040] Based on the above design, in this embodiment, several carrier plates 200 are provided, i.e., the carrier plates 200 adopt a segmented design. The height position of each carrier plate 200 relative to the support 100 can be adjusted by the fixing component 220, so that the main plane 230 of all carrier plates 200 can be at the same height. This is beneficial for the battery cells to be well adsorbed on the carrier plates 200, thereby improving the heating effect of the carrier plates 200 on the battery cells and making the battery cells heated evenly. Optionally, the first preset gap 210 is set between 0.5mm and 10mm, which helps to avoid the compression between adjacent carrier plates 200 after thermal expansion due to heat, which would cause the carrier plates 200 to deform. In other words, by designing the carrier plates 200 in segments and maintaining the first preset gap 210 between the carrier plates 200, the deformation of the carrier plates 200 can be controlled, thereby allowing the main plane 230 of the carrier plates 200 to fully fit with the battery cells, improving the uniformity of the battery cells' heating, avoiding the risk of the battery cells being pulled off from the welding ribbon, and improving the product yield.

[0041] Optionally, in this embodiment, the fixing member 220 is selected as a bolt, which facilitates the operator to disassemble and adjust the height position of the carrier plate 200. There can be 6 carrier plates 200. Of course, the operator can flexibly increase or decrease the number of carrier plates 200 according to the length of the solar cell string, which will not be elaborated here.

[0042] like Figure 1As shown, in this embodiment, the heating assembly 300 includes a heating rod 310 and a thermocouple 320, which are electrically connected. The heating rod 310 is used to heat the carrier plate 200, and the thermocouple 320 is used to control the heating temperature of the heating rod 310. Specifically, the heating rod 310 is externally connected to a heating power supply, which can heat the heating rod 310 by transmitting current. The thermocouple 320 controls the heating temperature of the heating rod 310, so that the temperature of the carrier plate 200 remains constant. It should be noted that the heating principle of the heating rod 310 and the temperature control principle of the thermocouple 320 in this embodiment are existing technologies, and will not be described in detail in this embodiment.

[0043] like Figures 2-4 As shown, in this embodiment, the lower end face of the suction cup assembly 400 protrudes above the second preset gap 410 of the main plane 230 of the carrier plate 200, and the second preset gap 410 is 0.2mm-5mm, preferably 1mm. The suction cup assembly 400 is an elastic element so that the battery sheet can adhere to the main plane 230 of the carrier plate 200. For example, the suction cup assembly 400 can be made of silicone, that is, the suction cup assembly 400 is made of silicone material and has a certain degree of elasticity. In other words, the suction cup assembly 400 is designed as an elastic structure, which facilitates deformation and allows the battery sheet to adhere to the main plane 230 of the carrier plate 200 after the suction cup assembly 400 adsorbs the battery sheet. When the second preset gap 410 is less than 0.2mm, the adhesion between the suction cup assembly 400 and the battery cell cannot be guaranteed, reducing the stability and reliability of the suction cup assembly 400. When the second preset gap 410 is greater than 5mm, the suction cup assembly 400, after its own deformation, cannot guarantee that the battery cell will adhere to the main plane 230 of the carrier plate 200. In other words, the deformation of the suction cup assembly 400 is usually no more than 5mm, resulting in uneven heating of the battery cell. Therefore, in this invention, the second preset gap 410 is set between 0.2mm and 5mm, which can ensure good adhesion between the suction cup assembly 400 and the battery cell, and at the same time, allow the battery cell to adhere to the main plane 230 of the carrier plate 200 after the suction cup assembly 400 has deformed, improving the uniformity of heating of the battery cell and thus avoiding the risk of the battery cell being pulled off from the solder ribbon.

[0044] Optionally, in this embodiment, each carrier plate 200 may be embedded with a plurality of suction cup components 400. For example, each carrier plate 200 may be embedded with 4, 6, 8 or other numbers of suction cup components 400.

[0045] In this embodiment, the solar cell string transport device includes a vacuum pumping assembly (not shown in the figure), a vacuum channel is provided in the carrier plate 200, one end of the vacuum channel is connected to the vacuum pumping assembly, and the other end of the vacuum channel is connected to the suction cup assembly 400. The vacuum pumping assembly provides negative pressure to the suction cup assembly 400, so that the suction cup assembly 400 can adsorb the solar cells.

[0046] Furthermore, such as Figure 1 As shown, the solar cell string transport device in this embodiment also includes a negative pressure channel 500. The negative pressure channel 500 is fixedly installed on the bracket 100. The negative pressure channel 500 is connected to the vacuum channel in the carrier plate 200. The end of the negative pressure channel 500 is provided with a first gas connector 510, which is connected to the vacuum pumping component.

[0047] Furthermore, a second air connector 240 is provided on the carrier plate 200, and a third air connector 520 is provided on the negative pressure channel 500. The second air connector 240 and the third air connector 520 are connected by a connecting pipe (not shown in the figure) to connect the negative pressure channel 500 with the vacuum channel inside the carrier plate 200. This allows the vacuuming component to extract air from the negative pressure channel 500 through the first air connector 510, making the negative pressure channel 500 a negative pressure state. Then, through the third air connector 520 on the negative pressure channel 500, the connecting pipe, and the second air connector 240 on the carrier plate 200, the vacuum channel inside the carrier plate 200 is made into a negative pressure state, thereby realizing the adsorption of the battery cell by the adsorption component.

[0048] Optionally, multiple second air connectors 240 are provided on the carrier plate 200, and multiple third air connectors 520 are provided on the negative pressure channel 500, with each second air connector 240 and third air connector 520 corresponding one-to-one. For example, two second air connectors 240 can be provided on each carrier plate 200.

[0049] like Figure 1 As shown, in this embodiment, the solar cell string handling device further includes a heat insulation block 600. One end of the heat insulation block 600 is mounted on the support 100, and the other end is connected to a robotic arm. The function of the heat insulation block 600 is to insulate the heat on the carrier plate 200 and the support 100, preventing heat transfer to the robotic arm, thereby protecting the robotic arm. The robotic arm is used to move the solar cell string handling device, thereby enabling the movement and handling of the solar cell string.
