Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production, and in particular to an edge-sealing and chamfering mechanism and edge-sealing equipment for photovoltaic modules. Background Art

[0002] Photovoltaic modules can generally be divided into single-glass photovoltaic modules and double-glass photovoltaic modules according to the number of glass plates in their composition structure. Among them, the edges of double-glass photovoltaic modules generally need to be sealed with tape.

[0003] The edge sealing of photovoltaic modules is typically performed automatically using edge sealing equipment. In related technologies, the edge sealing mechanism in the edge sealing equipment first applies the edge sealing tape to the side of the photovoltaic module. Then, a smoothing component in the edge sealing mechanism aligns the two edges of the tape with the two side surfaces of the photovoltaic module, completing the edge sealing. However, during this edge sealing process, some tape residue often remains at the corners of the photovoltaic module, affecting the sealing performance of the photovoltaic module edge and easily causing the photovoltaic module to fail due to moisture permeation.

[0050] See also Figures 1 to 3 The photovoltaic module edge sealing and chamfering mechanism 100 provided in the present application can be applied to the edge sealing equipment of the photovoltaic module. After sealing one side of the photovoltaic module 200, the tape remaining at the corner of the photovoltaic module can be bent and chamfered to improve the sealing of the photovoltaic module edge sealing.

[0051] The edge banding and chamfering mechanism 100 for a photovoltaic module provided in the present application includes a mounting plate 10, a chamfering drive assembly 20, and an edge banding roller assembly 30. The chamfering drive assembly 20 is fixedly mounted on the mounting plate 10. The edge banding roller assembly 30 is used to pre-attach the two edges of the tape to the two side surfaces of the photovoltaic module 200. The edge banding roller assembly 30 is connected to the output end of the chamfering drive assembly 20, and the chamfering drive assembly 20 is used to drive the edge banding roller assembly 30 to move along a first direction X. When the edge banding roller assembly 30 affixes the tape on one side of the photovoltaic module 200 to the corner of the photovoltaic module 200, the chamfering drive assembly 20 drives the edge banding roller assembly 30 to move along the first direction X toward the photovoltaic module 200, so as to bend the tape to the other adjacent side of the photovoltaic module 200.

[0052] It should be noted that the photovoltaic module 200 is generally rectangular, and the corners of the photovoltaic module 200 refer to the positions of the four corners of the photovoltaic module 200. When the edge-sealing roller assembly 30 affixes the tape on one side of the photovoltaic module 200 to the corner of the photovoltaic module 200, the tape on one side of the photovoltaic module 200 is affixed to the end position of that side. During the edge-sealing process of the photovoltaic module 200, the edge-sealing roller assembly 30 pre-bonds the two edges of the tape to the two side surfaces of the photovoltaic module 200, which means that the tape and the photovoltaic module 200 are preliminarily bonded. After the edge-sealing roller assembly 30, the tape and the photovoltaic module 200 are generally tightly bonded. Of course, in order to further ensure the firmness of the bond between the tape and the photovoltaic module 200, the photovoltaic module 200 that has passed through the edge-sealing roller assembly 30 can also be further smoothed and compacted.

[0053] The mounting plate 10 is used to install the chamfering drive assembly 20. The present application does not limit the specific structure of the mounting plate 10. For example, it can be a plate-like structure or a block-like structure, and can also be specifically configured according to the specific structure of the chamfering drive assembly 20. Since the edge-sealing roller assembly 30 is connected to the output end of the chamfering drive assembly 20, during the process of edge-sealing the photovoltaic assembly 200 by the edge-sealing equipment of the photovoltaic assembly, after the tape is attached to the edge of one side of the photovoltaic assembly 200, it is necessary to move the edge-sealing roller assembly 30 closer to the photovoltaic assembly 200 so that the two edges of the tape can be attached to the two side surfaces of the photovoltaic assembly 200 respectively. At this time, the mounting plate 10 can be driven to drive the edge-sealing roller assembly 30 to move closer to the photovoltaic assembly 200.

[0054] The chamfering drive assembly 20 is used to drive the edge banding roller assembly 30 to move along the first direction X. It is understood that the chamfering drive assembly 20 is a linear drive mechanism. For example, the chamfering drive assembly 20 can be a drive cylinder or an electric telescopic rod, but is not limited thereto. The chamfering drive mechanism drives the edge banding roller assembly 30 to move along the first direction X toward the photovoltaic module 200, so that the tape can be bent to the other adjacent side of the photovoltaic module 200. It is understood that, as shown in FIG. Figure 1 and Figure 2 As shown, in the space coordinate system, the first direction X is the axial direction of the edge banding roller assembly 30 approaching or moving away from the photovoltaic assembly 200 .

[0055] The edge-banding roller assembly 30 is used to apply the two edges of the tape to the two side surfaces of the photovoltaic module 200. For example, the edge-banding roller assembly 30 may include a plurality of edge-banding rollers 33a arranged along a second direction Y, wherein the second direction Y is perpendicular to the first direction X. When the edge-banding chamfering mechanism 100 of the photovoltaic module is edge-banding the photovoltaic module 200, the photovoltaic module 200 is generally arranged horizontally. It can be understood that the second direction Y is a direction in the horizontal plane that is perpendicular to the first direction X. For example, the edge-banding roller 33a may include two upper and lower sub-rollers. After the tape is applied to the edge of the photovoltaic module 200, as the edge-banding roller assembly 30 approaches the photovoltaic module 200, the photovoltaic module 200 enters between the upper and lower sub-rollers, so that the sub-rollers can pre-bond the two edges of the tape to the two side surfaces of the photovoltaic module 200. It should be noted that, taking the placement state of the edge sealing and chamfering mechanism 100 of the photovoltaic module during normal operation as an example, the two edges of the tape are the upper and lower edges of the tape, that is, the part where the tape on the upper and lower sides of the photovoltaic module 200 is greater than the thickness of the photovoltaic module 200.

[0056] The edge banding roller assembly 30 is connected to one end of the chamfering drive assembly 20, so that the chamfering drive assembly 20 can drive the edge banding roller assembly 30 to move along the first direction X. Figure 3 and Figure 4As shown, in some embodiments, the edge banding roller assembly 30 may include a connecting seat 31, a mounting seat 32, and a plurality of edge banding rollers 33a. The connecting seat 31 is fixedly connected to one end of the chamfering drive assembly 20, the mounting seat 32 is disposed on the connecting seat 31, the plurality of edge banding roller assemblies 30 are rotatably mounted on the mounting seat 32, and the plurality of edge banding rollers 33a are arranged along the second direction Y. It should be noted that, in the direction of movement of the photovoltaic module 200 passing through the plurality of edge banding rollers 33a, at least one of the plurality of edge banding rollers 33a is formed with a rectangular bonding groove 331a that cooperates with the photovoltaic module 200. During the edge banding process, the edge of the photovoltaic module 200 is embedded in the rectangular bonding groove to ensure that the adhesive tape and the photovoltaic module 200 are initially tightly bonded. To ensure that the photovoltaic module 200 can smoothly enter the rectangular bonding groove 331a, a guide slope may be provided at the opening of the rectangular bonding groove 331a. Correspondingly, other edge-sealing rollers 33a among the plurality of edge-sealing rollers 33a form a trapezoidal bonding groove 331b, which is used to press the tape toward the two side surfaces of the photovoltaic module 200. Of course, in the moving direction of the photovoltaic module 200 passing through the plurality of edge-sealing rollers 33a in sequence, the angle between the side wall of the trapezoidal bonding groove 331b and the surface of the photovoltaic module 200 can be gradually reduced.

[0057] The edge banding roller assembly 30 can bend the tape to the adjacent other side of the photovoltaic assembly 200 by moving along the first direction X towards the photovoltaic assembly 200, that is, one of the edge banding rollers 33a arranged at the end is moved along the first direction X towards the photovoltaic assembly 200 to push the tape at the corner of the photovoltaic assembly 200 to bend to the adjacent other side.

[0058] In the process of bending the tape at the corner of the photovoltaic module 200 to the adjacent other side, in order to avoid a hard collision between the edge-sealing roller 33a and the photovoltaic module 200 in the second direction Y, such as Figure 4 As shown, in some embodiments, the connecting seat 31 can be provided with a slide rail 311 extending along the second direction Y, and the mounting seat 32 can be slidably disposed on the slide rail 311. Of course, to ensure the bending and chamfering effect of the adhesive tape at the corners of the photovoltaic module 200, in some embodiments, the edge-sealing roller assembly 30 further includes a first elastic member 34, which is disposed along the second direction Y. One end of the first elastic member 34 is connected to the connecting seat 31, and the other end is connected to the mounting seat 32. This prevents the edge-sealing roller 33a from hard collision with the photovoltaic module 200 in the second direction Y, while also utilizing the first elastic member 34 to bend the adhesive tape at the corners of the photovoltaic module 200 and adhere it to the other side.

[0059] like Figure 3 and Figure 5As shown, in other embodiments, to prevent a hard collision between the edge-banding roller 33a and the photovoltaic module 200 in the second direction Y, the mounting base 32 of the edge-banding roller assembly 30 may further include a slide groove 321 extending along the second direction Y. One edge-banding roller 33a located at the end of the plurality of edge-banding rollers 33a is configured as an edge-banding chamfering roller 33b. That is, the edge-banding chamfering roller 33b is located at the end of the array of edge-banding rollers 33a. Alternatively, when the edge-banding roller assembly 30 applies the adhesive tape on one side of the photovoltaic module 200 to the corner of the photovoltaic module 200, the edge-banding roller 33a located closest to the photovoltaic module 200 is configured as the edge-banding chamfering roller 33b. The edge-banding chamfering roller 33b not only applies the two edges of the adhesive tape to the two side surfaces of the photovoltaic module 200 but also bends the adhesive tape. The edge chamfering roller 33b is slidably disposed in the slide groove 321 via a slider 322. Correspondingly, one end of the first elastic member 34 is connected to the slider 322, and the other end is connected to the end of the slide groove 321. The slider 322 can be disposed at the end of the rotating shaft of the edge chamfering roller 33b.

[0060] like Figure 3 As shown, in some embodiments, the edge banding roller assembly 30 further includes a limiting roller 35. The limiting roller 35 is disposed on the mounting base 32, and the central axis of the limiting roller 35 is parallel to the rotation axis of the edge banding roller 33a. The limiting roller 35 is used to limit the distance between the edge banding roller 33a and the photovoltaic module 200 in the first direction X. When the mounting plate 10 is driven to move along the first direction X, so that the edge banding roller assembly 30 applies the two edges of the tape to the two side surfaces of the photovoltaic module 200, when the limiting roller 35 abuts against the photovoltaic module 200, it indicates that the edge banding roller assembly 30 has moved into position. The limiting roller 35 can be a cylindrical roller structure, but is not limited thereto. The limiting roller 35 can also be rotatably disposed on the mounting base 32.

[0061] In some embodiments, the edge banding and chamfering mechanism 100 of the photovoltaic module further includes an edge banding track 50 and a closed drive assembly. The edge banding track 50 extends along the first direction X, and the mounting plate 10 is slidably mounted on the edge banding track 50. The edge banding drive assembly 60 is connected to the mounting plate 10 and is used to drive the edge banding roller assembly 30 to attach the two edges of the tape to the two side surfaces of the photovoltaic module 200. The edge banding drive assembly 60 can drive the edge banding roller assembly 30 to attach the two edges of the tape to the two side surfaces of the photovoltaic module 200 by driving the mounting plate 10 to move along the first direction X on the edge banding track 50 toward the photovoltaic module 200. It can be understood that the edge banding drive assembly 60 is also a linear drive assembly. For example, the edge banding drive assembly 60 can be a drive cylinder or an electric telescopic rod, but is not limited thereto.

[0062] In some embodiments, the edge banding drive assembly 60 can be connected to the mounting plate 10 via a buffer assembly 70. The buffer assembly 70 includes a connector 71 and a second elastic member 72. One end of the connector 71 is connected to the edge banding drive assembly 60, and the other end is slidably connected to the mounting plate 10. The second elastic member 72 is sleeved onto the connector 71, with one end of the second elastic member 72 connected to the end of the connector 71 proximal to the edge banding drive assembly 60 and the other end connected to the mounting plate 10. For example, the connector 71 can be a connecting shaft structure, with one end of the connector 71 connected to the edge banding assembly being provided with a shoulder structure, and one end of the second elastic member 72 being connected to the shoulder structure. The second elastic member 72 can also be a spring, but is not limited thereto. When the connector 71 is a connecting shaft structure, since the other end of the connector 71 is slidably connected to the mounting plate 10, the mounting plate 10 can be provided with a through-hole structure that cooperates with the connector 71. For example, the connector 71 can be provided through the through-hole. In order to prevent the mounting plate 10 from falling off the connecting member 71 , the end of the connecting member 71 away from the edge banding drive assembly 60 can be connected to a limiting block after passing through the through hole.

[0063] In the embodiment of the present application, the edge banding drive assembly 60 is connected to the mounting plate 10 through the buffer assembly 70. During the process of edge banding the photovoltaic assembly 200, when the edge banding drive assembly 60 drives the mounting plate 10 to move along the edge banding track 50 toward the photovoltaic assembly 200, the buffering effect of the buffer assembly 70 can prevent the edge banding roller 33a or the limiting roller 35 in the edge banding roller assembly 30 from colliding hard with the edge of the photovoltaic assembly 200.

[0064] like Figures 1 to 3 As shown, in some embodiments, the edge-sealing and chamfering mechanism 100 of the photovoltaic module further includes a smoothing assembly 40. The smoothing assembly 40 is also provided on the mounting plate 10 and is located on one side of the edge-sealing roller assembly 30 perpendicular to the first direction X. Figure 1 and Figure 3 As shown, the smoothing assembly 40 is located on one side of the edge-sealing roller assembly 30 in the second direction Y. The smoothing assembly 40 includes two smoothing rollers 41, which are used to respectively adhere the two edges of the tape to the two side surfaces of the photovoltaic module 200. It is understood that during the edge-sealing process of the photovoltaic module 200, the photovoltaic module 200 first passes through the edge-sealing roller assembly 30 and then the smoothing assembly 40. In this way, after the edge-sealing assembly adheres the two edges of the tape to the two side surfaces of the photovoltaic module 200, the smoothing assembly 40 can further press the tape and the photovoltaic module 200 together, ensuring a tight and smooth fit between the tape and the photovoltaic module 200.

[0065] It should be noted that, based on the functions of the edge banding roller assembly 30 and the smoothing assembly 40, their relative positions in the first direction X remain relatively unchanged during operation. Therefore, when the smoothing assembly 40 is also provided on the mounting plate 10, the edge banding drive assembly 60 can drive the smoothing assembly 40 and the edge banding roller assembly 30 toward the photovoltaic module 200 when driving the mounting plate 10 along the edge banding track 50. When the edge banding drive assembly 60 is connected to the mounting plate 10 via the buffer assembly 70, it can be understood that the buffer assembly 70 can also prevent hard collisions between the photovoltaic module 200 and the smoothing assembly 40 during the process of the smoothing assembly 40 smoothing the tape.

[0066] like Figures 1 to 5 As shown, the edge banding and chamfering mechanism 100 of the photovoltaic module provided in the above embodiment of the present application, when applied to the edge banding equipment of the photovoltaic module, after the tape is attached to the edge of the photovoltaic module 200, the edge banding drive assembly 60 drives the mounting plate 10 to move along the edge banding track 50 toward the direction close to the photovoltaic module 200, and the edge banding roller assembly 30 on the mounting plate 10 respectively sticks the two edges of the tape to the two side surfaces of the photovoltaic module 200. As the photovoltaic module 200 moves along the second direction Y, the end of the photovoltaic module 200 that first contacts the edge banding roller assembly 30 first enters the smoothing assembly 40. The photovoltaic component 200 continues to move along the second direction Y until the edge banding roller assembly 30 sticks the tape on one side of the photovoltaic component 200 to the corner of the photovoltaic component 200. At this time, the photovoltaic component 200 is detached from the edge banding roller assembly 30, and the photovoltaic component 200 is located on the side of the edge banding roller assembly 30 close to the smoothing assembly 40.
