Technical Field

[0001] This utility model relates to the technical field of vacuum transfer equipment for sheet materials, and more specifically, to a sheet material transfer device. Background Technology

[0002] During the production of solar cells, the cells need to be transferred and processed. The production process of solar cells involves multiple processes. When processing the cells using specific processes, they need to be transferred through transfer devices, typically suction cup structures.

[0003] During the reprocessing process, if debris or slag adheres to the battery cells from the previous production stage and falls off during transfer via the suction cup and platform, and is not detected and removed in time, the subsequent battery cells may develop microcracks when they are held in place by the suction cup. Utility Model Content

[0004] The purpose of this invention is to provide a sheet transfer device that can reduce the occurrence of microcracks during the transfer of battery cells.

[0005] The embodiments of this utility model can be implemented as follows:

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] It should be noted that the sheet material in this embodiment can be a battery cell, and the multiple in this embodiment can be understood as two or more quantities.

[0033] The following describes in detail, with reference to the accompanying drawings, the specific structure of a sheet transfer device provided by this utility model and the desired technical effects it brings.

[0034] Please refer to Figures 1-2The present invention provides a material transfer device 1 including a transfer body 100 and a transfer part 200. The transfer part 200 is connected to the transfer body 100. The transfer part 200 is spiral in shape. The outer peripheral wall of the transfer part 200 is curved and convex. The outer wall of the transfer part 200 is provided with a plurality of spaced vacuum adsorption holes 210 for adsorbing material.

[0035] Optionally, the cross-section of the transfer section 200 is circular or elliptical. In detail, the cross-section can be understood as a plane perpendicular to the extension direction of the transfer section 200.

[0036] Some existing flat suction cups have a large contact area when adsorbing material sheets, as the material sheets are in complete contact with the flat suction cup. Therefore, when some debris is attached to the suction cup or the material sheet, and the material sheet is adsorbed by the suction cup, the debris can easily cause microcracks in the material sheet, which can easily lead to damage to the material sheet.

[0037] Understandably, since the transfer section 200 is spiral-shaped and its outer wall is a protruding curved wall, the vacuum adsorption holes 210 on the transfer section 200 can effectively reduce the contact area between the material sheet and the transfer section 200 when adsorbing the material sheet. This can effectively reduce the occurrence of microcracks in the material sheet when it is transferred through the transfer section 200 in this embodiment, and thus reduce the occurrence of microcracks in the battery cell during transfer.

[0038] Furthermore, since the outer wall of the transfer section 200 is a curved wall, when debris falls onto the transfer section 200, the debris will also fall off under the action of the curved wall, making it less likely for debris to accumulate on the transfer section 200, and also reducing the occurrence of microcracks when the battery cells are adsorbed onto the transfer section 200.

[0039] In detail, in this embodiment, the outer peripheral wall of the transfer part 200 is also provided with a plurality of bearing planes 220, and a vacuum adsorption hole 210 is opened in a preset part of each bearing plane 220. That is to say, the plurality of vacuum adsorption holes 210 are provided in a one-to-one correspondence with the plurality of bearing planes 220.

[0040] Understandably, by setting the bearing surface 220, a bearing surface 220 for the material sheet can be provided, ensuring that the material sheet is more stable when it is adsorbed and driven to move by the vacuum adsorption hole 210.

[0041] It should be noted that the size of the bearing plane 220 in this embodiment should not be too large or too small. The size of the bearing plane 220 can be set according to the size of the material sheet and the size of the transfer part 200 based on experience, as long as it can ensure that the material sheet can be stably adsorbed on the vacuum adsorption hole 210.

[0042] Optionally, in some embodiments, a buffer layer (not shown) is provided on the bearing plane 220. The buffer layer is a flexible buffer film. That is, by providing a buffer layer, the hard contact between the material sheet and the transfer part 200 can be reduced. The buffer layer can effectively disperse the stress during the adsorption and release process, reduce local high-pressure points, and thus reduce the risk of microcracks. The thickness of the buffer film should be moderate, providing sufficient buffering effect without affecting the adsorption force of the suction cup. Optionally, the thickness is between 0.05 mm and 1 mm.

[0043] For example, the thickness of the buffer layer can be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.5mm, 0.6mm, 0.8mm or 1mm.

[0044] Of course, in some other embodiments, the thickness of the buffer layer can be greater than 1 mm, for example, it can be 1.2 mm, 1.5 mm, 1.6 mm or 2 mm.

[0045] Alternatively, the buffer layer can be fixed to the bearing surface 220 by adhesive bonding or by other means, such as by clips or screws.

[0046] The aforementioned buffer layer can be made of silicone, polyurethane, or fluororubber. Of course, in some other embodiments, the buffer layer can also be made of other materials with elasticity and resilience.

[0047] Optionally, in order to ensure that the vacuum adsorption hole 210 can also adsorb the material sheet under the action of the buffer layer, the buffer layer is provided with multiple hollow holes. That is to say, by setting the hollow holes, the vacuum adsorption hole 210 can adsorb the material sheet through the hollow holes.

[0048] Furthermore, due to the perforated design, even if debris falls onto the bearing surface 220, the debris will be contained within the perforated holes. As long as small debris does not protrude from the perforated holes, the debris will not cause microcracks in the material sheet when it is being adsorbed.

[0049] In this embodiment, the material transfer device 1 further includes a rotating shaft 300, and a transfer part 200 is spirally wound on the rotating shaft 300. One end of the rotating shaft 300 is connected to the transfer body 100. The rotating shaft 300 can drive the transfer part 200 to rotate relative to the transfer body 100 around its own axis.

[0050] Therefore, by setting the rotating shaft 300, the material sheet adsorbed on the transfer part 200 can also be driven to rotate during the rotation of the rotating shaft 300, which improves the freedom of material sheet transfer. Moreover, when placing the material sheet, the rotating shaft 300 can drive the material sheet to rotate until the material sheet faces downward, thereby breaking the vacuum and allowing the material sheet to fall to complete the sheet placement. There is no need to use back-blowing to break the vacuum, and there is no need to worry about the back-blowing air blowing the sheet out of shape during sheet placement, which allows for more precise sheet placement.

[0051] In detail, in this embodiment, the multiple vacuum pores are divided into multiple groups, and the multiple vacuum pores in each group are arranged at intervals along the axial direction of the rotating shaft 300, and the multiple groups of vacuum adsorption pores 210 are arranged at intervals around the circumferential direction of the rotating shaft 300.

[0052] Understandably, the different sets of vacuum adsorption holes 210 are not interconnected. By setting multiple sets of vacuum adsorption holes 210, the transfer unit 200 can transfer more material sheets, thereby improving the transfer efficiency of the material sheets.

[0053] It should be noted that the aforementioned transfer section 200 has multiple vacuum channels inside, and the number of vacuum channels is the same as the number of sets of vacuum adsorption holes 210 and they are connected one by one.

[0054] In detail, in this embodiment, the vacuum adsorption holes 210 are in two sets, and the two sets of vacuum adsorption holes 210 are evenly spaced around the rotating shaft 300 in the circumferential direction.

[0055] It should be noted that when adsorbing the material sheet, the rotating shaft 300 can rotate as needed, rotating 90° each time, and the direction can be set according to requirements. In order to further prevent the material sheet from cracking during adsorption, each vacuum adsorption hole 210 is required to not be connected to a material sheet twice consecutively, but to be connected at intervals. That is, after transferring a material sheet once, the vacuum adsorption hole 210 will not adsorb a material sheet again. When it is not adsorbing a material sheet, the debris around the vacuum adsorption hole 210 can be cleaned by a cleaning device (not shown in the figure).

[0056] In order to further improve the transfer efficiency of the material sheet, in this embodiment, there are multiple rotating shafts 300 and multiple transfer parts 200. Multiple rotating shafts 300 are arranged in a one-to-one correspondence with multiple transfer parts 200. Multiple rotating shafts 300 are spaced apart on the transfer body 100. That is to say, each transfer part 200 is spirally wound on a rotating shaft 300.

[0057] In detail, multiple rotating shafts 300 are spaced apart on the transfer body 100 along a preset direction, which is perpendicular to the circumference of the rotating shafts 300. In this embodiment, the preset direction is the length direction of the transfer body 100.

[0058] Please refer to Figure 3Of course, in some other embodiments, the material transfer device 1 may not have a rotating shaft 300. That is, in some embodiments, one end of the transfer part 200 is directly disposed on the transfer body 100. Similarly, in order to improve the transfer efficiency of the material transfer device 1, the number of transfer parts 200 can also be multiple and multiple transfer parts 200 are spaced apart on the transfer body 100. One end of the transfer part 200 is connected to the transfer body 100, and the multiple vacuum adsorption holes 210 on the transfer part 200 can also be set as a single set.

[0059] Optionally, in order to reduce microcracks in the material sheet caused by the transfer section 200 when adsorbing the material sheet, the transfer section 200 is made of a soft material. For example, the transfer section 200 can be made of silicone, polyurethane, natural rubber or fluororubber. Of course, in some other embodiments, the transfer section 200 can also be made of aluminum alloy or polyetheretherketone material.

[0060] Optionally, in some embodiments, the sheet transfer device 1 further includes a cleaning device for cleaning impurities on the outer surface of the transfer section 200. For example, the cleaning device can be an air blowing device to clean the outer surface of the transfer section 200 by blowing out gas. Of course, the cleaning device can also be other types of cleaning devices, such as cleaning brushes. The cleaning device can be installed on the transfer body 100 or set independently. No specific limitation is made on the cleaning device here.

[0061] In summary, the sheet transfer device 1 provided in this embodiment includes a transfer body 100 and a transfer section 200. The transfer section 200 is connected to the transfer body 100 and is spiral-shaped. The outer peripheral wall of the transfer section 200 is curved and convex. The outer wall of the transfer section 200 is provided with a plurality of spaced vacuum adsorption holes 210 for adsorbing sheet material. This effectively reduces the contact area between the sheet material and the transfer section 200, and the transfer section 200 also facilitates the removal of debris from its surface. This effectively reduces the occurrence of microcracks in the sheet material during transfer through the transfer section 200 in this embodiment, thus reducing the occurrence of microcracks in the battery cells during transfer.

[0062] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
