Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic technology, and particularly to a sheet material offline tooling. Background Art

[0002] In the photovoltaic production process, according to the upstream and downstream, it can include silica, metallurgical silicon, polysilicon, silicon rods, silicon wafers, solar cells, photovoltaic modules, arrays, and power station systems, etc. Among them, silicon wafers, solar cells, and photovoltaic modules are all in sheet form and can be called "sheet materials".

[0003] In a photovoltaic production line, there may be a situation where the production capacity of the front-end process is large while the production capacity of the back-end process cannot keep up. At this time, it is necessary to lift the materials that have passed through the front-end process (abbreviated as "offline") to avoid material blockage and ensure the normal operation of the production line. Of course, in some other situations, it is also necessary to perform offline operations on the sheet materials during the processing of photovoltaic modules. For example, to improve the power of photovoltaic modules, a reflective film tape is heated and pasted on the back glass of the photovoltaic module through a hot air gun. During the processing, if abnormalities such as bubbles, offsets, or fractures occur in the reflective film tape, and the back glass cannot be repaired at the current station, it also needs to be taken offline for processing.

[0004] However, in the related art, when performing offline operations on sheet materials such as photovoltaic modules or back glass, not only is the operation inconvenient, but during the offline operation, when lifting the short side of the photovoltaic module or back glass, it is easy to have an arc-shaped bend on the long side due to its own gravity, and then the sheet materials such as photovoltaic modules or back glass are prone to hidden cracks or fractures, resulting in poor quality of photovoltaic modules. Summary of the Utility Model

[0005] Based on this, the present application provides a sheet material offline tooling to solve the technical problem of how to improve the convenience of offline operation while taking into account the quality of photovoltaic modules.

[0006] The present application provides a sheet material offline tooling, including a tooling main body, a guiding connecting member, a supporting member, and an elastic member. The tooling main body includes a first supporting arm and a second supporting arm arranged oppositely. Both the first supporting arm and the second supporting arm are connected to the guiding connecting member. The second supporting arm is slidably connected to the guiding connecting member. The first supporting arm and the second supporting arm are both provided with the supporting member, and the supporting member is used to support the sheet material. The elastic member is connected to the second supporting arm, and the elastic member is used to drive the second supporting arm to approach the first supporting arm along the guiding connecting member.

[0007] In one embodiment, one end of the guiding connecting member is movably inserted through the first supporting arm, and the other end is movably inserted through the second supporting arm.

[0008] In one embodiment, another elastic member is provided between the first support arm and the guiding connecting member, and the another elastic member is configured to drive the first support arm to move along the guiding connecting member toward the second support arm.

[0009] In one embodiment, one end of the elastic member is connected to the first support arm, and the other end is connected to the second support arm. The elastic member has an elastic force that drives the first support arm and the second support arm to approach each other.

[0010] In one embodiment, one end of the guiding connecting member is fixedly connected to the first support arm, and the other end movably passes through the second support arm. The elastic member includes a spring that is sleeved on the guiding connecting member. One end of the spring is limited to the guiding connecting member, and the other end abuts against the second support arm.

[0011] In one embodiment, the sheet material offline tooling includes a bearing slider, and the second support arm is slidably connected to the guiding connecting member through the bearing slider.

[0012] In one embodiment, both the first support arm and the second support arm are in a U-shape with an open end, and the open end of the first support arm faces the open end of the second support arm.

[0013] In one embodiment, the support member includes a connecting portion and a supporting portion. The supporting portion is connected to the tooling main body through the connecting portion. The supporting portion is located below the tooling main body, and the distance between the supporting portion and the tooling main body is 20 mm to 40 mm.

[0014] In one embodiment, the material of the support member is selected from one of polyethylene terephthalate, high-density polyethylene, polyvinyl chloride, polypropylene, or polystyrene.

[0015] In one embodiment, the sheet material offline tooling includes a handle, and at least one end of the first support arm and / or the second support arm is connected with the handle; and / or, the sheet material offline tooling includes at least two of the guiding connecting members, and the guiding connecting members are arranged in parallel at intervals.

[0016] In the above-mentioned sheet material offline tooling, both the first support arm and the second support arm are provided with support members for supporting the sheet material. Since the second support arm is slidably connected to the guiding connecting member, when the second support arm moves relative to the first support arm along the guiding connecting member, the support members on the first support arm and the second support arm can pick up the sheet material. During the offline operation using the sheet material offline tooling of the present application, the first support arm and the second support arm can respectively lift the support members from the long side of the sheet material to reduce the probability of hidden cracks or chip cracks. Moreover, when using the sheet material offline tooling of the present application to perform the offline operation on the photovoltaic module, the operator only needs to operate the first support arm and the second support arm to move along the guiding connecting member so that the support members support the long side of the photovoltaic module, and the elastic member can clamp the support members on the long side of the photovoltaic module, thereby making the offline operation of the photovoltaic module simple and reliable. Therefore, the sheet material offline tooling of the present application can improve the offline operation convenience while taking into account the quality of the photovoltaic module.

[0030] Combined Figure 1 and Figure 2 As shown, a sheet material offline tooling 10 provided by an embodiment of the present application is adapted to perform offline operations on sheet materials. The sheet materials in this application include, but are not limited to, silicon wafers, solar cells, and photovoltaic modules. In some embodiments, the sheet material can also be a sheet material such as a back glass or a glass with a reflective film strip during the processing of photovoltaic modules. The type of sheet material that the sheet material offline tooling 10 of the present application is adapted to is not limited herein.

[0031] The sheet material offline tooling 10 includes a tooling main body 11, a guiding connecting member 12, a supporting member 13, and an elastic member 14. The tooling main body 11 includes a first support arm 111 and a second support arm 112 that are oppositely arranged. Both the first support arm 111 and the second support arm 112 are connected to the guiding connecting member 12, and the second support arm 112 is slidably connected to the guiding connecting member 12. Both the first support arm 111 and the second support arm 112 are provided with a supporting member 13, and the supporting member 13 is used to support the sheet material. The elastic member 14 is connected to the second support arm 112. The elastic member 14 is used to drive the second support arm 112 to approach the first support arm 111 along the guiding connecting member 12.

[0032] For the convenience of understanding, the following describes the working principle of the sheet material offline tooling 10 by combining the operation process of offline of photovoltaic modules with the sheet material offline tooling 10.

[0033] When the photovoltaic module needs to be taken offline, the operator places the sheet offline tooling 10 above the photovoltaic module, and makes the first support arm 111 and the second support arm 112 correspond to the long side of the photovoltaic module. Then, the first support arm 111 and the second support arm 112 are pushed away from each other along the guide connecting member 12, and when the distance between the first support arm 111 and the second support arm 112 exceeds the width of the photovoltaic module that needs to be taken offline, the first support arm 111 and the second support arm 112 are moved down to the long side of the photovoltaic module for alignment. As the first support arm 111 and the second support arm 112 approach each other along the guide connecting member 12, the support members 13 on the first support arm 111 and the second support arm 112 can support the photovoltaic module. In this way, the operator can lift the photovoltaic module through the first support arm 111 and the second support arm 112 and move it away from the production line to complete the offline operation.

[0034] Because in the sheet material off-line tooling 10 of the present application, the first support arm 111 and the second support arm 112 can be lifted from the long side of the photovoltaic module with the support member 13 respectively. The support of the long side of the photovoltaic module by the support member 13 makes it difficult for the photovoltaic module to bend in an arc due to its own gravity, so as to reduce the probability of hidden cracks or fragments. Moreover, when the sheet material off-line tooling 10 of the present application is used for off-line operation, the operator only needs to stand on the short side of the photovoltaic module to operate the first support arm 111 and the second support arm 112 to move along the guide connector 12, so that the support member 13 supports the long side of the photovoltaic module, and the elastic member 14 can clamp the support member 13 to the long side of the photovoltaic module. It can be seen that the sheet material off-line tooling 10 of the present application is simple and reliable for off-line operation of photovoltaic modules, and it takes into account the quality of photovoltaic modules while improving the convenience of off-line operation.

[0035] It should be noted that the elastic member 14 can be arranged between the second support arm 112 and the guide connecting member 12, or between the first support arm 111 and the second support arm 112, as long as the elastic member 14 can drive the second support arm 112 to approach the first support arm 111 along the guide connecting member 12.

[0036] Continue to combine Figure 1 and Figure 2As shown, in some embodiments, one end of the guiding connecting member 12 is fixedly connected to the first support arm 111, and the other end movably passes through the second support arm 112. The elastic member 14 includes a spring, and the spring is sleeved on the guiding connecting member 12. One end of the spring is limited to the guiding connecting member 12, and the other end abuts against the second support arm 112. In this way, when using the support members 13 on the first support arm 111 and the second support arm 112 to support the photovoltaic module to be unloaded, the spring drives the second support arm 112 to approach the first support arm 111 along the guiding connecting member 12, so that the support members 13 on the first support arm 111 and the second support arm 112 can clamp the photovoltaic module, and thus the photovoltaic module is not easily detached from the sheet unloading tooling 10, so as to improve the stability of the sheet unloading operation of the sheet unloading tooling 10 on the photovoltaic module.

[0037] In this embodiment, the diameter of the spring only needs to satisfy being sleeved on the guiding connecting member 12. It can be understood that when the spring is not compressed, the distance between the first support arm 111 and the second support arm 112 is slightly less than or equal to the width of the photovoltaic module. When picking up the photovoltaic module, the operator moves the first support arm 111 and the second support arm 112 in opposite directions, so that the distance between the first support arm 111 and the second support arm 112 is greater than the width of the photovoltaic module, and at this time the spring is in a compressed state. After aligning the support member 13 with the long side of the photovoltaic module, the elastic force when the spring restores deformation is used to make the support members 13 on the first support arm 111 and the second support arm 112 clamp the photovoltaic module, so as to improve the stability of the photovoltaic module unloading process. For photovoltaic modules of different widths, the elastic member 14 with different elastic magnitudes can be replaced to make the first support arm 111 and the second support arm 112 have a suitable opening distance, so as to ensure that the support members 13 on the first support arm 111 and the second support arm 112 can clamp the photovoltaic module.

[0038] In some embodiments, one end of the spring is limited to the guiding connecting member 12 by means of sleeving or clamping.

[0039] Combined with Figure 3 and Figure 4As shown, a limiting portion 121 is provided at the end of the guiding connecting member 12, and one end of the spring abuts against the limiting portion 121. In this embodiment, the two ends of the spring respectively abut between the limiting portion 121 and the second support arm 112. Thus, when the second support arm 112 is moved away from the first support arm 111, the second support arm 112 approaches the limiting portion 121 and compresses the spring. Correspondingly, during the process of the spring recovering its deformation, the elastic force of the spring drives the second support arm 112 away from the limiting portion 121, causing the second support arm 112 to approach the first support arm 111. Therefore, by using the elastic force of the spring on the second support arm 112, the second support arm 112 can be made to bring the corresponding support member 13 closer to the first support arm 111, and then the support members 13 on the first support arm 111 and the second support arm 112 can clamp both sides of the photovoltaic module, improving the stability during the process of the photovoltaic module coming off the production line.

[0040] In some embodiments, one end of the elastic member 14 is connected to the first support arm 111, and the other end is connected to the second support arm 112. The elastic member 14 has an elastic force that drives the first support arm 111 and the second support arm 112 to approach each other. Thus, the arrangement of the elastic member 14 can also meet the need for the support members 13 on the first support arm 111 and the second support arm 112 to clamp the photovoltaic module, thereby reducing the probability of the photovoltaic module detaching from the sheet material off-line tooling 10 and achieving improved stability of the sheet material off-line tooling 10 during the off-line operation of the photovoltaic module.

[0041] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the sheet material off-line tooling 10 includes a bearing slider 16, and the second support arm 112 is slidably connected to the guiding connecting member 12 through the bearing slider 16. In this embodiment, the characteristic of the bearing slider 16 being easy to slide is utilized to reduce the resistance when the second support arm 112 moves along the guiding connecting member 12, improving the smoothness of the second support arm 112 moving along the guiding connecting member 12, so as to perform the off-line operation on the photovoltaic module through the sheet material off-line tooling 10.

[0042] In some embodiments, both the first support arm 111 and the second support arm 112 are in a U-shaped form with an open end, and the open ends of the first support arm 111 and the second support arm 112 face each other. Thus, the first support arm 111 and the second support arm 112 enclose a rectangular frame corresponding to the rectangular photovoltaic module, so that when performing the off-line operation on the photovoltaic module, it is convenient for the operator to operate the first support arm 111 and the second support arm 112 on the wide side of the photovoltaic module, improving the operation convenience.

[0043] The sheet material off-line tooling 10 includes a handle 15. At least one end of the first support arm 111 and / or the second support arm 112 is connected with the handle 15. As Figure 1 and Figure 3As shown, handles 15 are connected to both ends of the first support arm 111 and both ends of the second support arm 112. The handles 15 can facilitate the operator to lift or lower the sheet material offline tooling 10, which is beneficial to improving the portability of the sheet material offline tooling 10 when performing the offline operation on the photovoltaic module.

[0044] Regarding the dimensions and shapes of the various components of the sheet material offline tooling 10, as long as they can meet the needs of operating the photovoltaic module, they are not limited herein. For example, in an embodiment where both the first support arm 111 and the second support arm 112 are in a C-shaped form with an open end, the long side length of the first support arm 111 and the second support arm 112 is 2000 mm to 3000 mm, and the short side length is 200 mm to 500 mm. Setting the first support arm 111 and the second support arm 112 with appropriate dimensions is beneficial for performing the offline operation on the photovoltaic module of the corresponding specification. In some embodiments, the long side length of the first support arm 111 and the second support arm 112 can specifically be 2000 mm, 2300 mm, 2400 mm, 2600 mm, 2800 mm, 2900 mm, or 3000 mm; the short side length can specifically be 200 mm, 230 mm, 240 mm, 260 mm, 280 mm, 290 mm, 300 mm, 430 mm, 450 mm, or 500 mm.

[0045] Regarding the materials of the first support arm 111 and the second support arm 112, including but not limited to steel pipes. For example, the materials of the first support arm 111 and the second support arm 112 are stainless steel pipes. In some embodiments, the stainless steel pipes adopted by the first support arm 111 and the second support arm 112 are square pipes, that is, the cross-sectional shape is square. Further, the first support arm 111 and the second support arm 112 are made of square pipes with a side length of 40 mm.

[0046] In some embodiments, the guiding connecting member 12 includes a round pipe. The diameter of the round pipe is less than or equal to 40 mm. The material of the guiding connecting member 12 includes but not limited to stainless steel, iron, or aluminum. The length of the guiding connecting member 12 is 1100 mm to 1200 mm. For example, the length of the guiding connecting member 12 can be 1100 mm, 1150 mm, or 1200 mm.

[0047] The guiding connecting member 12 can protect the mechanical balance of the overall structure of the sheet material offline tooling 10. Under the support and guidance of the guiding connecting member 12, the second support arm 112 can move stably relative to the first support arm 111 to meet the needs of the support member 13 to support or lower the photovoltaic module.

[0048] In some embodiments, the sheet material offline tooling 10 includes at least two of the guiding connectors 12, and the guiding connectors 12 are arranged in parallel at intervals to further improve the overall structural stability of the sheet material offline tooling 10. The number of the guiding connectors 12 may specifically be 2, 3, or 4, which is not limited herein.

[0049] In some embodiments, one end of the guiding connector 12 is movably inserted through the first support arm 111, and the other end is movably inserted through the second support arm 112. In this way, both the first support arm 111 and the second support arm 112 can move along the guiding connector 12, and then the first support arm 111 and the second support arm 112 can move closer to or away from each other to adapt to the support members 13 on the first support arm 111 and the second support arm 112 to pick up or unload the photovoltaic module.

[0050] It should be noted that since both the first support arm 111 and the second support arm 112 can move along the guiding connector 12, in order to improve the stability of the support members 13 on the first support arm 111 and the second support arm 112 for clamping the photovoltaic module, another elastic member (not shown in the figure) is provided between the first support arm 111 and the guiding connector 12. The another elastic member is used to drive the first support arm 111 to move along the guiding connector 12 towards the second support arm 112.

[0051] Continuing to combine Figure 3 and Figure 4 As shown, in some embodiments, the support member 13 includes a connecting portion 131 and a supporting portion 132. The supporting portion 132 is connected to the tooling main body 11 through the connecting portion 131, and the supporting portion 132 is located below the tooling main body 11. When the sheet material offline tooling 10 picks up the photovoltaic module, the supporting portion 132 is used to support the photovoltaic module. In this way, when the operator lifts the tooling main body 11, the support member 13 moves upward with the tooling main body 11, and then the supporting portion 132 lifts the photovoltaic module from the production line. Then, as the operator moves the tooling main body 11 away from the production line, the supporting portion 132 supports the photovoltaic module to leave the production line to complete the offline operation of the photovoltaic module.

[0052] In some embodiments, the distance between the supporting portion 132 and the tooling main body 11 is 20 mm to 40 mm to provide a suitable supporting space to meet the need of supporting the photovoltaic module. The distance between the supporting portion 132 and the tooling main body 11 may be 20 mm, 30 mm, or 40 mm. The number of the support members 13 is not specifically limited. For example, in some embodiments, two or more support members 13 are arranged at intervals on the first support arm 111. Two or more support members 13 are arranged at intervals on the second support arm 112.

[0053] The material of the support member 13 is selected from one of PET (Polyethylene terephthalate), HDPE (High Density Polyethylene), PVC (Polyvinyl chloride), PP (Polypropylene), or PS (Polystyrene). The support member 13 made of these materials has an appropriate hardness to reduce the chance of scratching the photovoltaic module while meeting the need for supporting the photovoltaic module.

[0054] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0055] The above embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
