[0002] At present, the mainstream products in the photovoltaic market have gradually evolved into double-glass photovoltaic modules with glass plates on both the front and back. They are favored because of their better light transmittance and efficiency. For double-glass photovoltaic modules, the traditional edge-sealing solution is to add a frame, but this greatly increases the production cost. Also, considering factors such as cost and maintenance, the market often requires double-glass photovoltaic modules to be frameless. Therefore, in the prior art, edge tapes are adhered to the edges of double-glass photovoltaic modules. However, the problem that follows is the process of pasting the edge tapes. Since most of the existing pasting processes use manual pasting, it is relatively complex and very likely to cause differences in edge wrapping, affecting the appearance and performance of the modules. Based on the above defects and deficiencies, it is necessary to improve the existing technology. Summary of the Invention

[0020] The present invention will be 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 be able to implement it, but the exemplified embodiments are not intended to limit the present invention.

[0021] Referring to Figure 1 As shown, it is a schematic structural diagram of the first embodiment of an edge-sealing device for a photovoltaic module of the present invention. The edge-sealing device of the present invention includes a substrate 10, and a tape bonding assembly 20, a tape pressing assembly 30, a tape cutting assembly 40 and an edge-sealing pressing wheel assembly 50 are arranged on the substrate 10. Installing each component on the substrate 10 uniformly facilitates driving the edge-sealing device as a whole to approach or move away from the photovoltaic module. During operation, when the edge-sealing device is close to the side of the photovoltaic module, the tape bonding assembly 20 is pushed out to bond a certain length of tape to the side of the photovoltaic module. The tape pressing assembly 30 can press the end of the tape against the side of the photovoltaic module. Then, the edge-sealing device moves forward as a whole, and the edge-sealing pressing wheel assembly 50 is close to the side of the photovoltaic module to fit the two sides of the tape to the upper and lower surfaces of the photovoltaic module until the edge-sealing of the side of the photovoltaic module is completed. Then, the tape pressing assembly 30 retracts, pulls the tape outward from the photovoltaic module to make the tape away from the photovoltaic module, which facilitates the tape cutting assembly 40 to cut the tape. After the edge-sealing pressing wheel assembly 50 completes all the edge-sealing tasks, it retracts, and the edge-sealing device returns to the starting point to wait for the next edge-sealing.

[0022] Specifically, referring to Figure 1As shown, the tape bonding assembly 20 is disposed at one end of the substrate 10, and can first bond a certain length of tape to the side surface of the photovoltaic module, facilitating the pasting of the tape to the upper and lower surfaces of the photovoltaic module. The tape pressing assembly 30 is located in the middle of the tape bonding assembly 20. On the one hand, it can press the tape bonded to the side surface of the photovoltaic module against the side surface of the photovoltaic module. On the other hand, after the side surface of the photovoltaic module is fully bonded, it can drive the tape away from the side of the photovoltaic module, facilitating the cutting of the tape. The tape pressing assembly 30 in this embodiment includes a pressing plate 31 and a pressing plate connecting plate 32. The pressing plate connecting plate 32 extends out of the front side of the tape pressing assembly 30, and the pressing plate 31 is installed at the front end of the pressing plate connecting plate 32, and the pressing plate 31 clamps the photovoltaic module. During edge sealing, the tape passes through the bonding assembly and simultaneously passes between the pressing plate 31 and the pressing plate connecting plate 32. When the tape presses against the side surface of the photovoltaic module, the side surface of the pressing plate connecting plate 32 abuts against the tape on its front side, pressing the tape against the side surface of the photovoltaic module. After edge sealing is completed, the pressing plate 31 moves away from the photovoltaic module. Due to the blocking of the pressing plate 31, the tape will not be in a V shape and can be pulled by the pressing plate 31 to move away from the side of the photovoltaic module, thus facilitating the cutting assembly 40 to cut the tape. Moreover, the adhesive surface of the tape adheres to the surface of the pressing plate 31, ensuring the stability of the end position of the tape and facilitating the next bonding. The edge sealing pressing wheel assembly 50 is located at the other end of the substrate 10, and is used to attach the upper and lower sides of the tape attached to the side of the photovoltaic module to the surface of the photovoltaic module. The cutting assembly 40 is disposed between the tape bonding assembly 20 and the edge sealing pressing wheel assembly 50, and the tape sequentially passes through the tape bonding assembly 20, the cutting assembly 40, and the edge sealing pressing wheel assembly 50. Thus, after the tape bonding assembly 20 completes the bonding of the tape on the side surface of the photovoltaic module, the cutting assembly 40 first cuts it, and then the edge sealing pressing wheel assembly 50 presses the tape between it and the tape bonding assembly 20 onto the surface of the photovoltaic module, ensuring the full utilization of the tape.

[0023] Referring to Figure 2As shown, it is a schematic diagram of the tape bonding assembly 20. The tape bonding assembly 20 includes a bonding cylinder 21, a bonding connecting plate 22, a tape reel 23, a guide shaft 24 and a bonding shaft 25. The bonding cylinder 21 pushes the bonding connecting plate 22 closer to or farther away from the photovoltaic module, so that the tape is bonded to the side of the photovoltaic module. The tape reel 23 automatically unwinds as the edge sealing device moves forward. The tape bypasses the guide shaft 24 and the bonding shaft 25. When the bonding cylinder 21 is pushed forward, the bonding shaft 25 presses the tape against the side of the photovoltaic module to achieve the bonding of the tape. The bonding cylinder 21 is installed on the substrate 10. The bonding connecting plate 22 is connected to the push rod of the bonding cylinder 21. The tape reel 23, the guide shaft 24 and the bonding shaft 25 are arranged on the top surface of the bonding connecting plate 22 and are driven to move uniformly by the bonding cylinder 21. In this embodiment, a plurality of bonding shafts 25 are provided, and the connection line of the plurality of bonding shafts 25 is parallel to the edge sealing direction, so that a section of tape can be compacted on the side of the photovoltaic module from multiple points to ensure the stability of the bonding between the tape and the side of the photovoltaic module. Further, the tape pressing assembly 30 is located between the bonding shafts 25 to press the tape between the two bonding shafts 25 against the side of the photovoltaic module to ensure the stability of the tape bonding. In this embodiment, to detect whether the tape on the tape reel 23 is out of stock, a detection sensor 26 is provided on the bonding connecting plate 22 on one side of the guide shaft 24. If the detection sensor 26 senses that no tape passes through, the machine stops and alarms. Further, referring to Figure 3 As shown, the bonding cylinder 21 is inclined towards the side away from the cutting assembly. When the bonding of the tape on the side of the photovoltaic module is completed and the bonding cylinder 21 retracts, due to the blockage of the pressing plate 31, the tape is driven away from the side of the photovoltaic module. A hypotenuse is formed by the tape between the end of the pressing plate 31 and the edge sealing pressing wheel assembly 50. If the bonding cylinder 21 drives the tape to retract perpendicular to the bonding direction, the length of the tape between the end of the pressing plate 31 and the edge sealing pressing wheel assembly 50 will increase, which is likely to stretch and deform the tape. However, when the bonding cylinder 21 is inclined, when the bonding cylinder 21 retracts, the distance between the end of the pressing plate 31 and the edge sealing pressing wheel assembly 50 remains unchanged, ensuring that the tape is flat and does not deform.

[0024] Referring to Figure 4As shown in the figure, it is a schematic structural diagram of the second embodiment of the present invention. Compared with the first embodiment, in this embodiment, the tape pressing assembly 30 further includes a pressing cylinder 33, the pressing cylinder 33 is installed on the bonding connecting plate 22, and the pressing plate connecting plate 32 is connected to the push rod of the pressing cylinder 33. The pressing cylinder 33 can push the pressing plate connecting plate 32 to move. When sealing the edge, the pressing cylinder 33 pushes out the pressing plate connecting plate 32, so that the side of the pressing plate connecting plate 32 presses the tape on the side of the photovoltaic module, ensuring the stability of the tape bonding; when the tape bonding is completed, the pressing cylinder 33 retracts, so that the pressing plate 31 presses against the bonding shaft 25, pressing the tape between the pressing plate 31 and the bonding shaft 25, ensuring the stability of the tape position after cutting, and facilitating the bonding of the tape end next time. At the same time, when the bonding ends, since one end of the tape is pressed by the edge sealing pressing wheel assembly 50 and is U-shaped and attached to the side of the photovoltaic module, the tape between the tape bonding assembly 20 and the edge sealing pressing wheel assembly 50 is still U-shaped due to the pulling force. At this time, the pressing cylinder 33 retracts, and by using the pressing of the pressing plate 31 against the bonding shaft 25, the tape can be pressed flat, so that the tape can be in full contact with the cutter 42, thus facilitating the cutter 42 to cut the tape.

[0025] To ensure that the tape can be cut, in another embodiment of the present invention, a cutting groove 34 is provided at a position on the pressing plate 31 corresponding to the tape cutting assembly 40. After the tape bonding is completed, the pressing cylinder 33 retracts, pressing the tape between the pressing plate 31 and the bonding shaft 25, and the tape adheres to the surface of the pressing plate 31. Then the bonding cylinder 21 retracts, the tape moves away from the side of the photovoltaic module, and the cutting assembly 40 extends and inserts into the cutting groove 34 to ensure that the tape on the surface of the pressing plate 31 is cut. In this embodiment, the tape cutting assembly 40 includes a cutting cylinder 41 and a cutter 42, and the cutter 42 is connected to the push rod of the cutting cylinder 41. The cutter 42 is pushed by the cutting cylinder 41 to extend and retract. To achieve rapid cutting of the tape, the cutting edge of the cutter 42 is serrated.

[0026] Refer to Figure 5As shown in the figure, the edge-sealing pressing wheel assembly includes an edge-sealing cylinder 51, a transition wheel 53, a clamping wheel 54, and a pressing wheel 55 that are sequentially connected to the edge-sealing cylinder 51 through a mounting plate 52. The edge-sealing cylinder 51 pushes the transition wheel 53, the clamping wheel 54, and the pressing wheel 55 to abut against the side surface of the photovoltaic module. The transition wheel 53 presses the flat tape flowing out from the tape bonding assembly 20 into a V shape, so that both sides of the tape are close to the upper and lower surfaces of the photovoltaic module. The clamping wheel 54 presses the V-shaped tape onto the upper and lower surfaces of the photovoltaic module, so that the tape is attached to the upper and lower surfaces of the photovoltaic module in a U shape. The pressing wheel 55 presses the tape from the upper and lower surfaces of the photovoltaic module to ensure the firm attachment of the tape to the upper and lower surfaces of the photovoltaic module. In order to gradually press the flat tape into a U shape, the transition wheel 53 and the clamping wheel 54 are vertically arranged. The transition wheel 53 is provided with an inclined wheel surface 56 acting on the tape, and the clamping wheel 54 is provided with an annular groove 57 having the same thickness as the photovoltaic module. With the guidance of the inclined wheel surface 56 and the annular groove 57, the tape is gradually deformed and finally attached to the upper and lower surfaces of the photovoltaic module. In order to ensure the stable attachment of the tape to the upper surface of the photovoltaic module, a plurality of pressing wheels 55 are horizontally arranged in parallel. The pressing wheels 55 are respectively connected to the upper and lower parts of the mounting plate 52, and press the tape and the surface of the photovoltaic module from the upper and lower parts respectively. In order to ensure that the tape can maintain a flat state during cutting, a tape blocking shaft 58 is provided on one side of the transition wheel 53 close to the cutting assembly 40. Since the tape blocking shaft 58 is cylindrical, when the tape adheres to the tape blocking shaft 58, the tape will not be deformed, so that the tape between the tape blocking shaft 58 and the tape bonding assembly 20 is flat, and the tape can be in full contact with the cutter 42, which is convenient for cutting. Further, in order to facilitate the pressing wheel 55 to clamp the photovoltaic module, so as to completely adhere the tape to the surface of the photovoltaic module, the distance between the pressing wheels 55 is smaller than the thickness of the photovoltaic module. Therefore, it is not convenient for the pressing wheel 55 to enter the position of the photovoltaic module. In this embodiment, the pressing wheels 55 are respectively connected to the mounting plate 52 through clamping cylinders. When the pressing wheels 55 are outside the photovoltaic module, the pressing cylinders 33 retract, and the distance between the upper and lower pressing wheels 55 is large, which is convenient for the pressing wheels 55 to enter the range of the photovoltaic module; after entering, the clamping cylinders extend, the pressing wheels 55 clamp the photovoltaic module, and the tape is pressed onto the surface of the photovoltaic module.

[0027] When the present invention is in operation, the tape on the tape reel 23 bypasses the guide shaft 24 and the bonding shaft 25. The bonding cylinder 21 extends, and the bonding connecting plate 22 is pushed out. The bonding shaft 25 presses the tape against the side of the photovoltaic module, and the tape is bonded to the side of the photovoltaic module. The pressing cylinder 33 extends, and the side of the pressing plate connecting plate 32 abuts against the side of the photovoltaic module, pressing the tape between the two bonding shafts 25 against the side of the photovoltaic module. The edge-sealing device moves along the side of the photovoltaic module. The edge-sealing cylinder 51 extends, and the tape blocking shaft 58, the gradient wheel 53, the clamping wheel 54, and the pressing wheel 55 abut against the side of the photovoltaic module, fitting the tape to the upper and lower surfaces of the photovoltaic module, and the pressing wheel 55 compacts the tape. The edge-sealing device continues to move along the side of the photovoltaic module. The pressing cylinder 33 retracts until the pressing plate 31 abuts against the bonding shaft 25, and the tape is pressed flat. The bonding cylinder 21 retracts, driving the tape away from the side of the photovoltaic module. Then, the cutting knife 42 extends and inserts into the cutting groove 34 to cut the tape. Since the bonding cylinder 21 is inclined, the length of the tape remains unchanged when it retracts, ensuring that the tape does not deform and ensuring the edge-sealing quality. Then, the edge-sealing device continues to move until the edge-sealing is completed.

Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
