[0002] Paper corner protectors, also known as edge boards, are one of the most popular packaging products in the world, used to replace wood packaging and other bulky packaging methods.

[0003] At present, the modules produced by the photovoltaic industry are generally protected by wrapping the four corners with paper corner protectors, which effectively prevents the modules from colliding with each other and rubbing against each other, thereby causing surface damage to the module frame. When packaging photovoltaic modules with paper corner protectors, the paper corner protectors need to be folded into the photovoltaic module frame. Currently, this step is done manually in the market, which increases the labor intensity of the staff. Not only can the manual folding of paper corner protectors not be applied to mass production, resulting in low productivity, but also the manual folding may be affected by human factors, resulting in uneven quality of the folded paper corner protector packaging, the installation position cannot be guaranteed to be accurate, and the installed paper corner protectors are easy to loosen and fall off. Summary of the invention

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0021] Reference Figure 1As shown, a schematic diagram of the structure of an embodiment of a paper corner protection corner suction cup of the present invention includes a guide shaft support 1, a suction connection plate 2, a suction cup 3 and a vacuum suction nozzle 4. The corner suction cup is connected to the mechanical arm through the guide shaft support 1, thereby driving the entire vacuum suction nozzle 4 to absorb the material through the suction cup 3. Specifically, since the paper corner is surrounded by the silo, in order to ensure that the corner suction cup can extend into the silo to absorb the paper corner, the suction cup 3 is a polygonal structure with a hollow middle part. The polygonal structure matches the shape of the paper corner, and the hollow part avoids the silo around the paper corner, so that the paper corner can be stably absorbed in the silo. The suction connection plate 2 spans the hollow part of the suction cup 3 and is fixedly connected to the suction cup 3. The guide shaft support 1 is fixedly connected to the middle of the suction connection plate 2, thereby creating enough space to connect the mechanical arm on the one hand, and enabling the mechanical arm to connect to the central axis of the corner suction cup on the other hand, ensuring the stability of the connection between the mechanical arm and the corner suction cup, and not affecting the suction cup 3 entering and exiting the silo. Furthermore, the vacuum suction nozzle 4 sucks the material through the suction plate 3. Figure 2 As shown, in this embodiment, a plurality of groups of airflow channels 5 are arranged in the suction plate 3, the vacuum suction nozzle 4 is connected to the airflow channels 5, and a plurality of suction holes 6 are arranged on the lower surface of the suction plate 3 and are connected to the airflow channels 5. This arrangement can achieve uniform distribution of airflow without setting too many vacuum suction nozzles 4. Specifically, each group of airflow channels 5 is connected to a vacuum suction nozzle 4, and each group of airflow channels 5 is connected to a plurality of suction holes 6, which increases the area of ​​the suction cup for adsorbing the paper corner protector and ensures that each part of the paper corner protector is uniformly sucked. Furthermore, after the corner wrapping suction cup absorbs the paper corner protector and places it on the paper corner protector packaging machine, the paper corner protector packaging machine matches the paper corner protector with the photovoltaic module, and pushes the paper corner protector upward along the side of the photovoltaic module for the first fold. When the pushed-up paper corner protector is spread on the upper surface of the photovoltaic module and buckled into the frame of the photovoltaic module, the paper corner protector packaging machine cannot perform this operation due to steering. Therefore, the suction plate 3 of this embodiment also includes at least one discount angle 7. The robotic arm adjusts the direction of the discount angle 7 to be consistent with the direction of the corner of the photovoltaic module. The robotic arm drives the suction plate 3 to move inward from the outside of the photovoltaic module along the centerline direction of the corner of the photovoltaic module. The lower surface of the suction plate 3 is abutted against the upper surface of the photovoltaic module, and the paper corner protector is pressed against the upper surface of the photovoltaic module. When the suction plate 3 moves to the inner edge of the frame of the photovoltaic module, the robotic arm stops moving in this direction to complete the second fold. Finally, the robotic arm drives the suction plate 3 to press down, and inserts the paper corner protector into the gap on the inner side of the frame of the photovoltaic module along the centerline direction of the corner of the photovoltaic module to complete the corner wrapping.

[0022] Reference Figure 3As shown, further, since the corners of photovoltaic modules are generally 90°, and each corner suction cup in this embodiment is only responsible for the corner of one corner of the photovoltaic module, the suction plate 3 is provided with a discount angle 7, and the discount angle 7 is a right angle. At the same time, in order to facilitate the smoothing of the paper corner edge on the surface of the photovoltaic module during the second fold, the side opposite to the discount angle 7 is set as the horizontal side of the suction plate 3. Further, a self-adhesive foam patch 8 is provided around the suction hole 6, which, on the one hand, forms a buffer when the paper corner is sucked, and on the other hand, when the paper corner edge is smoothed, the paper corner edge can be guided so that the paper corner edges on both sides are closed inward and fit on the surface of the photovoltaic module.

[0023] Reference Figure 4 As shown, it is a schematic diagram of the structure of the second embodiment of the present invention. In order to prevent the robot from having too large an impact force when picking up and releasing materials, a buffer mechanism is provided between the guide shaft support 1 and the suction plate 3. Specifically, in this embodiment, the buffer mechanism is a first buffer cylinder 9, which is fixedly connected to the guide shaft support 1, and the connecting plate is fixedly connected to the push rod of the first buffer cylinder 9. The suction plate 3 is connected to the first buffer cylinder 9, and the first buffer cylinder 9 directly provides buffering for the suction plate 3.

[0024] Reference Figure 5 and Figure 6 As shown, it is a structural schematic diagram of embodiment 3 of the present invention. In this embodiment, the buffer mechanism includes a second buffer cylinder 10 and a material suction bracket 11. The second buffer cylinder 10 is fixedly connected to the material suction connecting plate 2, and the material suction bracket 11 is fixedly connected to the push rod of the second buffer cylinder 10. The vacuum suction nozzle 4 is connected to the material suction bracket 11. The second buffer cylinder 10 is connected to the vacuum suction nozzle 4 to directly provide buffering for the vacuum suction nozzle 4. To ensure that the vacuum suction nozzle 4 can contact the paper corner protector, the suction plate 3 is provided with a suction cup groove 12 for the vacuum suction nozzle 4 to pass through. In this way, the vacuum suction nozzle 4 can move up and down relative to the suction plate 3. When the vacuum suction nozzle 4 is extended, the vacuum suction nozzle 4 first contacts the paper corner protector, sucks the paper corner protector, and moves the position. When the paper corner protector is placed at the corresponding position on the paper corner protector packaging machine, since the paper corner protector is relatively thin, even if the vacuum suction nozzle 4 no longer sucks air, the paper corner protector is not easy to separate from the vacuum suction nozzle 4. If the vacuum suction nozzle 4 moves up at this time, the paper corner protector cannot continue to move upward due to the obstruction of the suction plate 3, thereby facilitating the placement of the paper corner protector. Further, in order to facilitate the installation of the vacuum suction nozzle 4, a suction cup mounting groove 13 is provided on the suction bracket 11, and the vacuum suction nozzle 4 is clamped in the suction cup mounting groove 13. The suction cup mounting groove 13 is long and strip-shaped, which is convenient for the vacuum suction nozzle 4 to adjust the position in the suction cup mounting groove 13. At the same time, at least one vacuum suction nozzle 4 is provided in the suction cup mounting groove 13, and the number and position of the vacuum suction nozzle 4 can be selected according to the size of the paper corner protector.
