Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, specifically relating to a sealing mechanism for a photovoltaic module. Background Technology

[0002] Currently, edge sealing tape can be used to seal the edges of photovoltaic modules. The edge sealing mechanism attaches the sealing tape to the edge of the photovoltaic module to achieve edge sealing.

[0003] However, if the sealing pressure is too high during the sealing process, it may cause the photovoltaic modules before lamination to break. If the sealing pressure is too low, the sealing tape may not be able to adhere tightly to the photovoltaic modules before lamination, which may easily cause air bubbles.

[0004] In summary, both excessive and insufficient edge sealing pressure can lead to an increased defect rate in photovoltaic modules before lamination. Utility Model Content

[0005] Based on the above analysis, this utility model aims to provide a sealing mechanism for photovoltaic modules to solve the problem that the failure rate of photovoltaic modules before lamination is increased due to the inability to detect the sealing pressure in the prior art.

Detailed Implementation

[0038] The preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the present invention to illustrate the principle of the present invention.

[0039] Example 1

[0040] This embodiment provides a sealing mechanism for a photovoltaic module, see [link to documentation]. Figures 1 to 2 ,include:

[0041] The surface sealing wheel assembly 9 includes a first gap for accommodating the edge of a photovoltaic module to which sealing tape is bonded, and the inner wall of the first gap can abut against the sealing tape 1 located on the upper and lower surfaces of the photovoltaic module. The surface sealing wheel assembly 9 is used for sealing the upper and lower surfaces of the photovoltaic module.

[0042] The tape edge-gathering wheel assembly 10 is located downstream of the surface sealing wheel assembly 9 and includes a second gap for accommodating the edge of the photovoltaic module with the edge sealing tape bonded thereon or the edge sealing tape, and the inner wall of the second gap can abut against the edge sealing tape or the edge sealing tape located on the upper and lower surfaces of the photovoltaic module.

[0043] The first pressure sensor group 11 includes at least two first pressure sensors, which are respectively located above and below the surface sealing wheel group 9 to detect the sealing pressure on the upper and lower surfaces of the photovoltaic module.

[0044] The second pressure sensor group 12 includes at least two second pressure sensors, which are respectively located above and below the tape edge-gathering wheel group 10 to detect the edge-gathering pressure on the upper and lower surfaces of the photovoltaic module.

[0045] For example, along the direction of movement of the photovoltaic module, the surface sealing wheel group 9 and the tape edge-gathering wheel group 10 are arranged sequentially. In this embodiment of the invention, "photovoltaic module" refers to a photovoltaic module without tape edge sealing.

[0046] Compared with the prior art, the edge sealing mechanism of the photovoltaic module provided in this embodiment, by setting a first pressure sensor group 11 and a second pressure sensor group 12, can detect the edge sealing pressure of the upper and lower surfaces of the photovoltaic module in real time during the edge sealing process, so as to ensure that the edge sealing pressure is within a suitable range, thereby reducing the occurrence of cracks or bubbles and effectively improving the edge sealing yield of the photovoltaic module.

[0047] In some embodiments, the edge sealing mechanism provided by this utility model further includes: a side edge sealing wheel group 8, located upstream of the surface edge sealing wheel group 9. The side edge sealing wheel group 8 includes a first side edge sealing wheel and a second side edge sealing wheel arranged symmetrically. A first groove is formed between the first side edge sealing wheel and the second side edge sealing wheel. The edge of the photovoltaic module with the edge sealing tape is inserted into the first groove, and the edge sealing tape on the side of the photovoltaic module abuts against the bottom wall of the first groove to seal the side edge of the photovoltaic module.

[0048] Considering that the side sealing wheel assembly 8, surface sealing wheel assembly 9, and tape edge-collecting wheel assembly 10 target different positions of the photovoltaic module, the distances between these three wheel assemblies and the centerline of the photovoltaic module gradually decrease. It should be noted that the centerline of the photovoltaic module refers to the central axis along the direction of movement of the photovoltaic module. For example, if the photovoltaic module has a cuboid structure, it includes a centerline parallel to the long side and passing through the midpoint of the short side, and a central axis parallel to the short side and passing through the midpoint of the short side. If the long side of the photovoltaic module is sealed, the distances between the centerline of the photovoltaic module parallel to the long side and the side sealing wheel assembly 8, surface sealing wheel assembly 9, and tape edge-collecting wheel assembly 10 gradually decrease.

[0049] Understandably, to facilitate the feeding of photovoltaic modules and the supply of sealing tape 1, the aforementioned photovoltaic module sealing mechanism also includes a tape clamp 2, a module feeding wheel assembly 6, and a tape longitudinal bending assembly 7. The tape clamp 2 is located upstream of the side sealing wheel assembly 8, the surface sealing wheel assembly 9, and the tape take-up wheel assembly 10. The sealing tape 1 can be wound around the tape clamp 1. The tape longitudinal bending assembly 7 is located between the tape clamp 2 and the surface sealing wheel assembly 9. The tape longitudinal bending assembly 7 has a second groove with a V-shaped cross-section. The free end of the sealing tape 1 passes through the second groove. The module feeding wheel assembly 6 supports the photovoltaic module, and the opening of the second groove faces the module feeding wheel assembly 6. After the tape passes through the second groove, the tape will become V-shaped under the action of the second groove (V-shape). That is, the two opposite sides of the tape are folded, so that the two opposite sides of the tape are located on the upper and lower surfaces of the photovoltaic module, respectively. That is, after passing through the side sealing wheel group 8, the tape is folded and initially bonded to the photovoltaic module.

[0050] Specifically, the structure of the side sealing wheel assembly 8 includes a first side sealing wheel and a second side sealing wheel arranged symmetrically. A first groove is formed between the first side sealing wheel and the second side sealing wheel. The edge of the photovoltaic module with the sealing tape 1 is inserted into the first groove, and the sealing tape on the side of the photovoltaic module abuts against the bottom wall of the first groove. Through the concave surface of the first groove, the edge of the sealing tape 1 is tightly attached to the side of the photovoltaic module, thereby sealing the side of the photovoltaic module.

[0051] Specifically, the structure of the surface sealing wheel assembly 9 includes an upper surface sealing wheel and a lower surface sealing wheel arranged symmetrically. A first gap is formed between the upper surface sealing wheel and the lower surface sealing wheel. The upper surface sealing wheel can abut against the sealing tape 1 located on the upper surface of the photovoltaic module, so that the sealing tape 1 is tightly attached to the upper surface of the photovoltaic module. The lower surface sealing wheel can abut against the sealing tape 1 located on the lower surface of the photovoltaic module, so that the sealing tape 1 is tightly attached to the lower surface of the photovoltaic module, thereby achieving edge sealing of the upper and lower surfaces of the photovoltaic module.

[0052] It should be noted that in practical applications, the gap between the upper and lower sealing wheels needs to be adjusted according to the different thicknesses of the photovoltaic modules to accommodate modules of varying thicknesses. For example, the ratio of the photovoltaic module thickness to the maximum width of the first gap is 1:1.1 to 1.2, such as 1:1.10, 1:1.13, 1:1.15, 1:1.18, or 1:1.20. By limiting the ratio of the photovoltaic module thickness to the maximum width of the first gap within this range, the sealing pressure on the photovoltaic module can be maintained within a suitable range.

[0053] Specifically, the tape edge-gathering wheel assembly 10 includes a symmetrically arranged first tape edge-sealing wheel and a second tape edge-sealing wheel, with a second gap between them. The first tape edge-sealing wheel can abut against the edge-sealing tape on the upper surface of the photovoltaic module, and the second tape edge-sealing wheel can abut against the edge-sealing tape on the lower surface of the photovoltaic module. The edge-sealing tape between two adjacent photovoltaic modules can be folded and abut against the first and second tape edge-sealing wheels. When the edge-sealing tape between two adjacent photovoltaic modules passes through the tape edge-gathering wheel assembly 10, the assembly folds the tape, thus gathering the edge of the edge-sealing tape downstream of the photovoltaic module.

[0054] The upper surface sealing wheel, lower surface sealing wheel, first tape sealing wheel, and second tape sealing wheel are all deformable wheels. The material of the deformable wheels can be high-density sponge wheels. The upper end of the upper surface sealing wheel and the lower end of the lower surface sealing wheel are respectively connected to a first pressure sensor, and the upper end of the first tape sealing wheel and the lower end of the second tape sealing wheel are respectively connected to a second pressure sensor. The pressure is detected by the deformation of the upper surface sealing wheel, lower surface sealing wheel, first tape sealing wheel, and second tape sealing wheel.

[0055] In order to detect defects (e.g., cracks or bubbles) in the photovoltaic modules after edge sealing in a timely manner, the edge sealing mechanism of the photovoltaic modules also includes an image acquisition unit 13 (e.g., a smart camera). The image acquisition end of the image acquisition unit 13 faces the tape edge-gathering wheel group 10. The image acquisition unit 13 is used to acquire images of the photovoltaic modules after the edge sealing tape has been gathered. Operators can judge whether there are defects in the edge sealing of the photovoltaic modules based on the images, and then judge whether the photovoltaic modules after edge sealing are qualified.

[0056] In order to achieve tensioning and guiding of the sealing tape 1, the sealing mechanism of the photovoltaic module also includes a guide wheel 3, a first tensioning wheel 4 and a second tensioning wheel 5. Along the direction from the tape clamp 2 to the tape longitudinal bending assembly 7, the guide wheel 3, the first tensioning wheel 4 and the second tensioning wheel 5 are sequentially arranged between the tape clamp 2 and the tape longitudinal bending assembly 7. The free end of the sealing tape 1 passes through the guide wheel 3, the first tensioning wheel 4 and the second tensioning wheel 5 in sequence and is then inserted into the groove of the tape longitudinal bending assembly 7.

[0057] It should be noted that, in order to achieve stable installation of the above components, the edge sealing mechanism of the photovoltaic module also includes a mounting bracket 14, a side edge sealing wheel group 8, a surface edge sealing wheel group 9, a tape edge-gathering wheel group 10, a tape clamping shaft 2, a module feeding wheel group 6, a tape longitudinal bending component 7, an image acquisition unit 13, a guide wheel 3, a first tensioning wheel 4 and a second tensioning wheel 5, all of which are mounted on the mounting bracket 14.

[0058] Based on the above structure, the specific working process of the edge-sealing mechanism for the photovoltaic module provided in this embodiment is as follows:

[0059] Place the edge sealing tape 1 onto the tape clip 2;

[0060] Tear off the free end of the sealing tape 1, with the sticky side of the sealing tape 1 facing the photovoltaic module;

[0061] After pulling the free end of the sealing tape 1 counterclockwise through the guide wheel 3, the free end is passed through the gap between the first tensioning wheel 4 and the second tensioning wheel 5. The free end is then passed clockwise around the first tensioning wheel 4 and counterclockwise around the second tensioning wheel 5 to achieve tensioning of the sealing tape 1.

[0062] Insert the free end of the sealing tape 1 into the second groove of the tape longitudinal bending component 7. Under the action of the second groove, the cross section of the sealing tape 1 is bent into a V shape. At the same time, the V-shaped sealing tape 1 contacts the side of the photovoltaic module.

[0063] The photovoltaic module and the edge sealing tape 1 move synchronously to the first side edge sealing wheel and the second side edge sealing wheel. The edge of the photovoltaic module with the edge sealing tape 1 is inserted into the first groove. Through the concave surface of the first groove, the edge sealing tape 1 is tightly attached to the side edge of the photovoltaic module, thereby sealing the edge of the photovoltaic module.

[0064] The photovoltaic module and the sealing tape 1 move synchronously to the upper and lower surface sealing wheels. The upper surface sealing wheel can press against the sealing tape 1 located on the upper surface of the photovoltaic module, so that the sealing tape 1 is tightly attached to the upper surface of the photovoltaic module. The lower surface sealing wheel can press against the sealing tape 1 located on the lower surface of the photovoltaic module, so that the sealing tape 1 is tightly attached to the lower surface of the photovoltaic module, thereby sealing the upper and lower surfaces of the photovoltaic module. At the same time, the first and second tape sealing wheels deform, and the first pressure sensor group 11 detects the sealing pressure.

[0065] The photovoltaic modules and the edge sealing tape 1 move synchronously, causing the edge sealing tape 1 located between two adjacent photovoltaic modules to move to the first edge sealing wheel and the second edge sealing wheel. The first edge sealing wheel can abut against the edge sealing tape located on the upper surface of the photovoltaic module, and the second edge sealing wheel can abut against the edge sealing tape located on the lower surface of the photovoltaic module. The edge sealing tape located between two adjacent photovoltaic modules can be folded and abut against the first edge sealing wheel and the second edge sealing wheel, so that the two layers of edge sealing tape 1 are tightly bonded. At the same time, the first edge sealing wheel and the second edge sealing wheel deform, and the second pressure sensor group 12 detects the edge-gathering pressure.

[0066] Example 2

[0067] This embodiment provides an edge-sealing mechanism for a photovoltaic module, the structure of which is basically the same as that of the edge-sealing mechanism for a photovoltaic module provided in Embodiment 1, the difference being:

[0068] For judging the edge sealing pressure and edge finishing pressure, and judging the defects in the acquired images, the edge sealing mechanism of the photovoltaic module in this embodiment adopts automatic judgment instead of the manual judgment used in the edge sealing mechanism of the photovoltaic module in Embodiment 1.

[0069] Specifically, the first pressure sensor group collects the sealing pressure of the upper surface and the sealing pressure of the lower surface and transmits it to the controller. The controller receives the sealing pressure of the upper surface and the sealing pressure of the lower surface and determines whether the sealing pressure of the upper surface and the sealing pressure of the lower surface are within the threshold range (e.g., 0.4 to 0.6 MPa). If they are within the threshold range, a sealing valid signal is sent to the display for display. If they are below the threshold range (i.e., below 0.4 MPa), a bubble abnormality signal is sent to the display for display. If they are above the threshold range (i.e., above 0.6 MPa), a crack abnormality signal is sent to the display for display. At the same time, the photovoltaic modules with crack abnormalities are further inspected by electroluminescence and microscopic inspection equipment.

[0070] The second pressure sensor group collects the edge-receiving pressure and transmits it to the controller. The controller receives the edge-receiving pressure and determines whether it is within the threshold range (e.g., 0.5–0.6 MPa). If it is within the threshold range, a valid edge-receiving signal is sent to the display for display. If it is below the threshold range (i.e., below 0.5 MPa), a bubble abnormality signal is sent to the display for display. If it is above the threshold range (i.e., above 0.6 MPa), a crack abnormality signal is sent to the display for display. At the same time, the photovoltaic modules with crack abnormalities are further inspected by electroluminescence and microscopic examination equipment.

[0071] The image acquisition unit acquires images of the photovoltaic module after edge sealing and transmits them to the controller. The controller stores an edge sealing defect image library, which includes edge sealing defects such as bubbles, folds, and wrinkles. The controller receives the image of the photovoltaic module after edge sealing and extracts the edge sealing tape area from the image. It compares the image with the images in the edge sealing defect image library according to the boundary shape comparison method to determine whether there is an edge sealing defect. If so, the edge sealing needs to be resealed; otherwise, the edge sealing of the photovoltaic module is deemed qualified.

[0072] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
