[0024] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Please refer to Figures 1 to 4A thin-sheet product buffering and correcting mechanism includes a material placing plate 1, a pressure claw 122, and a driving mechanism, wherein the material placing plate 1 is used to stack thin-sheet products (not shown in the figure); a plurality of pressure claws 122 are arranged at intervals along the circumference of the material placing plate 1; the driving mechanism is arranged on the lower side of the material placing plate 1, and acts on the pressure claws 122, so that the plurality of pressure claws 122 are synchronously approached to the thin-sheet product or synchronously away from the thin-sheet product. The plurality of pressure claws 122 here can move synchronously, so that the thin-sheet product placed on the material placing plate 1 can be accurately and efficiently centered and corrected, which is beneficial to the subsequent process.

[0028] Furthermore, the driving mechanism includes a gear plate 4, on which a plurality of cam grooves 41 are arranged, and the plurality of cam grooves 41 correspond to a plurality of pressing claws 122 one by one, and the pressing claws 122 slide against the inner wall of the cam groove 41; the cam groove 41 has a starting point 411 and an end point 412, and the distance between the starting point 411 and the center of the gear plate 4 is greater than the distance between the end point 412 and the center of the gear plate 4; the pressing claws 122 are slidably connected to the material placing plate 1; the gear plate 4 is parallel to the material placing plate 1, and the gear plate 4 can rotate along its central axis. Figure 1 and 2 As shown, when the gear plate 4 rotates, the cam groove 41 acts on the pressing claw 122, so that it can move in the direction of approaching the thin-sheet product or away from the thin-sheet product. The structure is simple and the stability is high.

[0029] Furthermore, if Figure 4 As shown, in the cam groove 41, the distance from the inner wall of the cam groove 41 to the center of the gear plate 4 gradually decreases from the starting point 411 to the end point 412. Such an arrangement enables the clamping claw to operate smoothly during the movement of approaching or moving away from the thin sheet product, which is beneficial to improving the centering quality of the thin sheet product and preventing the pressing claw 122 from damaging the thin sheet product.

[0030] In this embodiment, the sheet product buffering and correcting mechanism includes a frame plate 42, a gear plate 4 is located between the frame plate 42 and the material placement plate 1, the gear plate 4 is rotatably mounted on the frame plate 42, and the material placement plate 1 and the frame plate 42 are fixedly connected via a connecting shaft 2. The sheet product buffering and correcting mechanism also includes a driving gear 5, a driving motor 51 is mounted on the frame plate 42, and the driving gear 5 is mounted on the output shaft of the driving motor 51 and meshes with the gear plate 4. When in use, the driving motor 51 drives the driving gear 5 so that the gear plate 4 rotates around its central axis, thereby driving the claw to move.

[0031] like Figure 1 and Figure 2As shown, the material placing plate 1 includes a movable plate 11 and a fixed plate 12, wherein: the pressing claw 122 is installed on the fixed plate 12, and the thin-sheet products are stacked on the movable plate 11; a through hole 121 is passed through the fixed plate 12, and the telescopic member 3 passes through the through hole 121 to drive the movable plate 11 to move longitudinally relative to the fixed plate 12. The movable plate 11 here can adjust the longitudinal height through the telescopic member 3, which is conducive to the use of the correction mechanism. Specifically, the thin-sheet products on the movable plate 11 are stacked, and as the upper layer of products are taken away, the lower layer of products are not easily grabbed by components of other processes, such as suction cups, etc. At this time, the movable plate 11 is lifted by the telescopic member 3 so that the longitudinal height of the top layer of thin-sheet products can always remain consistent, which is conducive to the development of the next process.

[0032] like Figure 2 As shown, the movable plate 11 includes a base portion 111, a platform portion 112 and a connecting plate 1121. The platform portion 112 is arranged on the upper side of the base portion 111 for supporting the thin-sheet product. A plurality of limit blocks 1111 are arranged on the base portion 112, and the plurality of limit blocks 1111 are arranged at intervals along the circumference of the material placing plate 1. The limit blocks 1111 here enclose a space for placing the thin-sheet product. The connecting plate 1121 is arranged at the telescopic end of the telescopic member 3, and the connecting plate 1121 is connected to the base portion 111 or connected to the platform portion 112 through the base portion 111. The platform portion 112 here is higher than the base portion 111 in the longitudinal direction, and the two are detachably connected. This is conducive to reducing the processing difficulty and production cost of the movable plate 11. In this embodiment, the connecting plate 1121 can be embedded in or pass through the through hole 121.

[0033] In this embodiment, at least two first guide shafts 1122 are provided on the movable plate 11, and a positioning frame 125 corresponding to the first guide shaft 1122 is provided on the fixed plate 12. The first guide shaft 1122 passes through the corresponding positioning frame 125 and is slidably connected with the positioning frame 125. The first guide shaft 1122 here is installed on the connecting plate 1121, and there are two first guide shafts 1122. The positioning frame 125 here cooperates with the first guide shaft 1122 to ensure that the movable plate 11 does not rotate in the circumferential direction during use.

[0034] like Figure 2 As shown, the telescopic member 3 includes a telescopic portion 31 and a drive shaft 32. Optionally, the telescopic portion 31 includes but is not limited to a cylinder, a hydraulic cylinder or an electric push rod. The drive shaft 32 is arranged at the telescopic end of the telescopic portion 31, and the connecting plate 1121 is connected to the telescopic end of the telescopic portion 31 through the drive shaft 32. The drive shaft 32 here passes through the frame plate 42 and the gear plate 4 in sequence, and is slidably connected to the frame plate 42 and the gear plate 4 respectively.

[0035] like Figure 3As shown, in this embodiment, an extension groove 123 is provided through the fixed plate 12, and the extension groove 123 extends toward the movable plate 11; the pressing claw 122 includes an extension portion 1221, which is embedded in the extension groove 123, and a roller 124 is arranged at the first end thereof, and the roller 124 is arranged in the cam groove 41, and the second end of the extension portion 1221 extends to the side of the fixed plate 12 close to the movable plate 11, and a working portion 1223 is arranged at the second end of the extension portion 1221. The working portion 1223 here is forked, which is conducive to more contact with the thin sheet product to apply pressure to it. The way in which the roller 124 and the cam groove 41 cooperate can effectively reduce friction, which is conducive to the smooth and stable movement of the pressing claw 122.

[0036] In this embodiment, the base 111 is provided with an avoidance notch 1112, which is provided corresponding to the pressing claw 122 and is used to accommodate the pressing claw 122. The avoidance notch 1112 prevents the base 111 from interfering with the pressing claw 122, which is conducive to increasing the stroke of the pressing claw 122, so that the buffer correction mechanism can adapt to the correction of thin-film products of more specifications.

[0037] Furthermore, the extension portion 1221 is provided with a limit protrusion 1222, which is located on the side of the fixed plate 12 away from the movable plate 11; the limit protrusion 1222 is provided with a slider 132, and the fixed plate 12 is provided with a slide rail 131 adapted to the slider 132. The extension direction of the slide rail 131 is parallel to the extension direction of the extension slot 123.

[0038] In this embodiment, a wind knife 6 is provided on the material placing plate 1, and the air outlet of the wind knife 6 faces the thin-sheet product. The wind knife 6 is used to blow air to the thin-sheet product so that gaps are formed between the thin-sheet products on the upper layer and the thin-sheet products float upward, which is conducive to the grabbing components of the next process, such as suction cups, to grab a single thin-sheet product at a time.

[0039] This embodiment also provides a photovoltaic cell processing device, including a frame (not shown in the figure), a material taking suction cup (not shown in the figure) and the aforementioned thin sheet product buffering and correcting mechanism, the material taking suction cup is movably arranged on the frame, and the material taking suction cup is used to grab the thin sheet product on the material placing plate 1.
