Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a lamination device. Background Technology

[0002] The production process of photovoltaic modules involves a series of complex procedures, among which lamination is a crucial step. To prevent issues such as adhesive overflow or air bubbles during lamination, edge-sealing tape is typically applied to the two long sides of the photovoltaic module before lamination. After lamination, a tape-tearing machine is used to remove the edge-sealing tape from the photovoltaic module.

[0003] To facilitate tape removal after lamination, a certain length of sealing tape needs to extend from two opposite corners of the photovoltaic module when applying the edge sealing tape. After installing the lamination frame before lamination, the tape end is pushed onto the frame for the subsequent tape-tearing machine to grasp. However, in automated processes, there is a problem where the tape end tends to tilt inwards towards the photovoltaic module after being pushed onto the lamination frame. During lamination, the inwardly tilted tape end easily sticks to the front of the photovoltaic module, preventing the tape-tearing machine from grasping and tearing off the edge sealing tape after lamination. This triggers alarms, stops the line, and impacts production efficiency and product quality. Utility Model Content

[0004] Therefore, it is necessary to provide a lamination device to address the problem of sealing tape sticking to photovoltaic modules during the lamination process.

[0005] This application provides a lamination apparatus, comprising:

[0006] A laminator, the laminator being used for laminating photovoltaic modules, the laminator being provided with a feed inlet;

[0007] A conveying mechanism for conveying photovoltaic modules and feeding the photovoltaic modules from the feed inlet into the laminator;

[0008] A tape straightening mechanism is provided at the feed inlet and is used to guide the diagonal sealing tape of the photovoltaic module to bend outward toward the photovoltaic module.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the tape straightening mechanism includes a scraper having a contact surface for contacting the sealing tape, the normal direction of the contact surface having an obtuse angle with the conveying direction of the conveying mechanism.

[0011] In one embodiment, the installation angle is greater than or equal to 105° and less than or equal to 165°.

[0012] In one embodiment, the tape straightening mechanism further includes a rotary drive connected to the scraper, the rotary drive being used to drive the scraper to rotate in order to adjust the installation angle of the scraper.

[0013] In one embodiment, the tape straightening mechanism further includes a moving drive member connected to the scraper, the moving drive member being used to drive the scraper to move along the width direction of the feed inlet to adjust the installation position of the scraper.

[0014] In one embodiment, the tape correction mechanism further includes a camera electrically connected to the rotary drive and the moving drive. The camera is used to acquire the position and tilt angle of the sealing tape, and can control the moving drive to adjust the installation position of the scraper according to the position of the sealing tape, and can control the rotary drive to adjust the installation angle of the scraper according to the tilt angle of the sealing tape.

[0015] In one embodiment, the feed inlet has an upper edge disposed opposite to the conveying mechanism, one end of the scraper is connected to the upper edge, and the other end of the scraper extends toward the conveying mechanism and contacts and engages with the conveying mechanism.

[0016] In one embodiment, the scraper is a soft rubber part.

[0017] In one embodiment, the conveying mechanism includes a conveyor belt, one end of which extends into the laminator from the feed port.

[0018] In one embodiment, the number of tape straightening mechanisms is two, and the two tape straightening mechanisms are spaced apart at the feed inlet along the width direction of the feed inlet.

[0019] In the aforementioned lamination device, by setting a tape correction mechanism at the feed inlet of the laminator, when the photovoltaic module with the lamination frame is conveyed by the conveyor mechanism through the feed inlet, the tape correction mechanism can guide the sealing tape on the opposite corner of the photovoltaic module to bend outwards towards the outside of the photovoltaic module, preventing the sealing tape on the opposite corner of the photovoltaic module from tilting inwards. This prevents the sealing tape from sticking to the front of the photovoltaic module during the lamination process, ensuring that the tape tearing machine can accurately grab and tear off the sealing tape after lamination, thus ensuring stable and orderly production on the production line.

[0036] See Figure 1 as well as Figure 2 , Figure 1 A schematic diagram of the lamination apparatus according to an embodiment of this application is shown. Figure 2 It shows Figure 1 The image shows a partial enlarged view of the laminating apparatus in section A. Specifically, one embodiment of the laminating apparatus includes a laminator 10, a conveying mechanism 20, and a tape straightening mechanism 30. The laminator 10 is used to laminate the photovoltaic module 40 and is provided with a feed inlet 11. The conveying mechanism 20 is used to convey the photovoltaic module 40 and feed the photovoltaic module 40 into the laminator 10 from the feed inlet 11. The tape straightening mechanism 30 is provided at the feed inlet 11 and is used to guide the diagonal sealing tape 41 of the photovoltaic module 40 to bend outwards towards the photovoltaic module 40.

[0037] In the above-mentioned lamination device, by setting a tape correction mechanism 30 at the feed inlet 11 of the laminator 10, when the photovoltaic module 40 with the lamination frame is conveyed by the conveying mechanism 20 through the feed inlet 11, the tape correction mechanism 30 can guide the sealing tape 41 on the opposite corner of the photovoltaic module 40 to bend outwards towards the photovoltaic module 40, preventing the sealing tape 41 on the opposite corner of the photovoltaic module 40 from tilting inwards, thereby preventing the sealing tape 41 from sticking to the front of the photovoltaic module 40 during the lamination process. This ensures that the tape tearing machine can accurately grab and tear off the sealing tape 41 after lamination, ensuring stable and orderly production of the production line.

[0038] See Figure 2 as well as Figure 3 In one embodiment, the tape straightening mechanism 30 includes a scraper 31 having a contact surface 311 for contacting the sealing tape 41, combined with... Figure 4 as well as Figure 5The contact surface 311 has an obtuse angle S1 with the conveying direction S2 of the conveying mechanism 20. Specifically, the contact surface 311 of the scraper 31 faces the outside of the photovoltaic module 40 at an inclined angle. Thus, when the conveying mechanism 20 feeds the photovoltaic module 40 with the laminated frame into the laminator 10 from the feed port 11, the scraper 31 can brush over the sealing tape 41. Since the contact surface 311 has an obtuse angle with the conveying direction S2 of the conveying mechanism 20, when the scraper 31 brushes over the sealing tape 41, it can apply pressure to the sealing tape 41 towards the outside of the photovoltaic module 40, thereby guiding the sealing tape 41 to bend towards the outside of the photovoltaic module 40 and preventing the sealing tape 41 at the opposite corners of the photovoltaic module 40 from tilting inward and sticking to the front of the photovoltaic module 40.

[0039] For example, the installation angle α is 105°≤α≤165°, such as 105°, 115°, 120°, 135°, 150°, 165°, etc. Specifically, if the installation angle α of the scraper 31 is too small, it may not be able to contact the sealing tape 41, while if the installation angle α of the scraper 31 is too large, it will squeeze the sealing tape 41 towards the inside of the photovoltaic module 40. Therefore, by configuring the installation angle α of the scraper 31 to 105°≤α≤165°, it can be ensured that the scraper 31 can stably contact the sealing tape 41, and it can also be ensured that the scraper 31 guides the sealing tape 41 to bend towards the outside of the photovoltaic module 40.

[0040] See Figure 3 Optionally, in one embodiment, the feed inlet 11 has an upper edge 12 disposed opposite to the conveying mechanism 20. One end of the scraper 31 is connected to the upper edge 12, and the other end of the scraper 31 extends toward the conveying mechanism 20 and contacts and engages with the conveying mechanism 20. This ensures that when the photovoltaic module 40 passes through the feed inlet 11, the scraper 31 can stably contact the photovoltaic module 40 and press the sealing tape 41 toward the outside of the photovoltaic module 40, guiding the sealing tape 41 to bend toward the outside of the photovoltaic module 40, thus ensuring the stability of the scraper 31 in correcting the angle of the sealing tape 41.

[0041] Optionally, in one embodiment, the scraper 31 is a soft rubber part, thus ensuring that the scraper 31 does not scratch the photovoltaic module 40 when it slides over it. For example, in one embodiment, the material of the scraper 31 can be polyethylene terephthalate (PET), polyvinylidene fluoride (PVF), and polyvinylidene fluoride (PVDF).

[0042] It is worth noting that in the above embodiments, since the scraper 31 is a soft rubber part and the scraper 31 is in contact with the conveying mechanism 20, when the conveying mechanism 20 is running, due to the friction between the scraper 31 and the conveying mechanism 20 or between the scraper 31 and the photovoltaic module 40, the scraper 31 will be in an arc-shaped plate that bends towards the inside of the laminator 10. The normal direction S1 of the contact surface 311 of the scraper 31 mentioned above refers to the normal direction of the contact surface 311 when it is in a straight state and the scraper 31 is not subjected to external force.

[0043] See Figure 2 In one embodiment, the tape correction mechanism 30 further includes a rotary drive 32 connected to the scraper 31. The rotary drive 32 drives the scraper 31 to rotate, thereby adjusting the installation angle α of the scraper 31. Specifically, the rotary drive 32 can drive the scraper 31 to rotate in a vertical direction to adjust the installation angle α of the scraper 31. In this way, the installation angle α of the scraper 31 can be flexibly adjusted according to the tilt angle of the sealing tape 41. For example, when the sealing tape 41 is tilted towards the inside of the photovoltaic module 40, the rotary drive 32 drives the scraper 31 to rotate counterclockwise to reduce the installation angle α, thereby ensuring that the scraper 31 has the best correction effect on the sealing tape 41 and ensuring that the sealing tape 41 can be scraped to the outside of the photovoltaic module 40.

[0044] For example, in one embodiment the rotary drive 32 is an electric shaft. In other embodiments, it can also be a motor or the like, as long as it can drive the scraper 31 to rotate around the vertical axis. There are no restrictions here.

[0045] See Figure 2 In one embodiment, the tape straightening mechanism 30 further includes a moving drive component 33 connected to the scraper 31. The moving drive component 33 drives the scraper 31 to move along the width direction of the feed inlet 11 to adjust the installation position of the scraper 31. Specifically, the moving drive component 33 can drive the scraper 31 to move along the upper edge 12 of the feed inlet 11 to adjust the installation position of the scraper 31. In this way, the installation position of the scraper 31 can be flexibly adjusted according to the position of the sealing tape 41 so that the position of the scraper 31 is aligned with the position of the sealing tape 41, ensuring that the scraper 31 can stably scrape across the sealing tape 41.

[0046] See Figure 2 Optionally, in one embodiment, the tape correction mechanism 30 further includes a camera 34, which is electrically connected to the rotary drive 32 and the moving drive 33. The camera 34 is used to acquire the position and tilt angle of the sealing tape 41, and can control the moving drive 33 to adjust the installation position of the scraper 31 according to the position of the sealing tape 41, and can control the rotary drive 32 to adjust the installation angle α of the scraper 31 according to the tilt angle of the sealing tape 41.

[0047] Specifically, camera 34 can acquire images of the sealing tape 41 diagonally opposite the photovoltaic module 40. Using image recognition technology, the position and tilt angle of the sealing tape 41 can be determined. Then, based on the position of the sealing tape 41, the moving drive component 33 can be controlled to adjust the installation position of the scraper 31 to ensure that the scraper 31 is aligned with the sealing tape 41. At the same time, based on the tilt angle of the sealing tape 41, the rotating drive component 32 can be controlled to adjust the installation angle of the scraper 31 to ensure the best correction effect of the scraper 31 on the sealing tape 41, thereby ensuring that the sealing tape 41 can be scraped to the outside of the photovoltaic module 40.

[0048] Optionally, in one embodiment, the conveying mechanism 20 includes a conveyor belt, one end of which extends into the laminator 10 from the feed port 11, thus ensuring that the conveying mechanism 20 can smoothly feed the photovoltaic module 40 into the laminator 10. Understandably, in other embodiments, the conveying mechanism 20 may also be a sprocket and chain mechanism or a synchronous belt mechanism, etc., and is not limited thereto.

[0049] See Figure 3 In one embodiment, there are two tape correction mechanisms 30, which are spaced apart along the width of the feed inlet 11. Specifically, sealing tape heads for the tape tearing machine are pre-reserved at both opposite corners of the photovoltaic module 40. By setting two tape correction mechanisms 30 at the feed inlet 11 of the laminator 10, the two tape correction mechanisms 30 are respectively aligned with the two short sides of the photovoltaic module 40. Thus, when the photovoltaic module 40 passes through the feed inlet 11 under the conveying mechanism 20, the two tape correction mechanisms 30 can respectively correct the sealing tape heads at the two opposite corners, thereby improving efficiency.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
