Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic technology, and in particular to a method, apparatus, electronic device, and storage medium for replacing modules. Background Technology

[0002] Photovoltaic film bonding technology, as an important means of surface protection and functional enhancement of photovoltaic modules, is widely used in building-integrated photovoltaics and outdoor decoration. In related technologies, reliable adhesion between the film and the module surface is typically achieved through the synergistic operation of plasma surface treatment and adhesive layer preparation. With the increasingly widespread application of full-color photovoltaic film-bonded modules in complex environments, their replacement frequency has significantly increased, placing higher demands on the control of residual adhesive after film peeling.

[0003] In existing film replacement methods, the plasma treatment of photovoltaic module surface results in a uniform energy distribution, which leads to insufficient surface energy difference between the module edge and the middle area. When replacing the film, the edge is prone to residual adhesive due to high adhesion force. Moreover, this uniform adhesion force distribution can easily cause edge sealing failure. After long-term use, moisture seepage can cause interlayer delamination, thereby affecting the maintenance efficiency and long-term reliability of the module. Summary of the Invention

Detailed Implementation

[0022] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0023] The following description, with reference to the accompanying drawings, outlines a method, apparatus, electronic device, and storage medium for replacing components according to embodiments of the present disclosure.

[0024] Figure 1This is a schematic flowchart illustrating a component replacement method provided in an embodiment of this disclosure.

[0025] like Figure 1 As shown, the method includes the following steps: Step 101: Perform plasma treatment with gradually varying energy on the surface of the photovoltaic module from the edge to the center, so that the surface energy of the edge region is higher than that of the middle region on the surface of the photovoltaic module. In the preparation process of full-color photovoltaic film-coated modules, in order to optimize the adhesion-related characteristics of the module surface and reduce the problem of residual adhesive when replacing the film, it is necessary to perform plasma treatment with energy gradient on the photovoltaic module surface.

[0026] In practice, plasma treatment is performed along the edge to the center of the photovoltaic module. By gradually controlling the energy output of the plasma, different areas of the module receive differentiated energy effects. The edge areas require relatively high-energy plasma treatment to enhance the adhesion and sealing of subsequent film application, while the center areas are treated with relatively low-energy plasma to reduce the risk of adhesive residue during film peeling. When the plasma interacts with the module surface, high-energy areas induce more significant physicochemical changes, such as the formation of more abundant oxygen-containing polar groups or a denser cross-linked layer, thereby increasing the surface energy of that area. Low-energy areas moderately improve surface hydrophilicity and adhesion properties while avoiding excessively high surface energy that could lead to excessive adhesion between the adhesive and the surface. Through this gradual energy plasma treatment, a surface energy gradient distribution is ultimately achieved on the photovoltaic module surface, with the edge areas having a higher surface energy than the center areas. This provides crucial assurance for the stable implementation of subsequent film application processes and low-residue replacement after long-term module use.

[0027] Step 102: Based on the surface energy gradient distribution, an adhesive layer of a first thickness is printed in the edge region, and an adhesive layer of a second thickness is printed in the middle region; wherein, the first thickness is greater than the second thickness. After constructing the surface energy gradient distribution on the photovoltaic module surface, adhesive layers need to be printed on different areas of the module based on this surface energy gradient distribution to achieve differentiated adaptation between adhesive layer performance and surface energy characteristics. During the printing process, an adhesive layer with a first thickness is printed on the edge areas with higher surface energy; an adhesive layer with a second thickness is printed on the middle areas with lower surface energy, and the first thickness is greater than the second thickness.

[0028] The logic behind this thickness design is that the edge areas with higher surface energy require a thicker adhesive layer to enhance sealing and protection. This first-thickness adhesive layer forms an effective waterproof barrier, preventing the penetration of external moisture during long-term use and avoiding the risk of delamination. Conversely, the middle areas with lower surface energy use a thinner second-thickness adhesive layer, reducing the adhesion area between the adhesive and the module surface during subsequent film peeling, thus lowering the possibility of residual adhesive. During the printing process, a printing technology that precisely differentiates the thickness of each area can be employed, ensuring that the adhesive layer thickness in the edge and middle areas consistently meets the design requirements for the first and second thicknesses, respectively. This allows the thickness distribution of the adhesive layer to synergistically interact with the surface energy gradient distribution on the module surface, laying the foundation for subsequent lamination processes of the full-color photovoltaic film module and low-residue replacement after long-term use.

[0029] Step 103: Apply a first pressure to the edge region and a second pressure to the middle region to match the bonding requirements of different regions; wherein the first pressure is greater than the second pressure.

[0030] After printing the adhesive layer on the edge and center areas of the photovoltaic module, a segmented pressing operation is required to match the bonding needs of different areas. For the edge areas, since they have already formed a high surface energy state and are covered with the first thickness of adhesive layer, the first pressure needs to be applied for pressing. Greater pressure can promote full contact and tight adhesion between the adhesive layer and the module surface, further enhancing the sealing performance of the adhesive layer, ensuring that a solid waterproof barrier is formed in the edge areas, effectively preventing external moisture from seeping into the module during long-term use, and avoiding interlayer delamination problems.

[0031] For the middle area, since it is in a low surface energy state and covered by a second-thickness adhesive layer, a second pressure less than the first pressure is applied for pressing. This pressure strength can ensure that the adhesive layer and the component surface form a bond strength that meets the usage requirements, ensuring the structural stability of the component during normal operation, while avoiding excessive compression and deformation of the adhesive layer due to excessive pressure, thereby reducing the probability of adhesive residue during subsequent film replacement. Ultimately, by applying differentiated pressure, the bonding effect of each area of ​​the component is precisely matched with the functional requirements, providing support for reducing the residual adhesive rate after replacement and improving the overall reliability of the component.

[0032] The module replacement method disclosed herein, through this application, utilizes plasma treatment with gradually varying energy from the edge to the center of the photovoltaic module surface. This actively constructs a surface energy gradient where the surface energy of the edge region is higher than that of the center region. By matching a thicker adhesive layer and greater applied pressure in the edge region, and a thinner adhesive layer and less applied pressure in the center region, it ensures reliable adhesion in the edge region during film application while avoiding adhesion imbalance caused by insufficient surface energy difference between regions. Therefore, it solves the technical problem that existing plasma treatments with uniform energy distribution result in insufficient surface energy difference between the module edge and center regions, leading to residual adhesive at the edge during film application replacement, which affects module maintenance efficiency and long-term reliability. This method achieves the technical effects of reducing residual adhesive at the edge during film application replacement, improving photovoltaic module maintenance efficiency, ensuring long-term module reliability, and simultaneously meeting the adhesion requirements during film application.

[0033] In some embodiments, the plasma treatment of the photovoltaic module surface along the edge to the center direction, which gradually changes energy to form a surface energy gradient distribution on the photovoltaic module surface, such that the surface energy of the edge region is higher than that of the middle region, includes: The photovoltaic module is scanned from the edge to the center using an adjustable power plasma processing device. A high-power processing mode is used for the edge region, and a low-power processing mode is used for the center region. The scanning speed of the adjustable power plasma processing device in the edge region is less than that in the center region.

[0034] When performing plasma treatment with gradually varying energy on the surface of a photovoltaic module to create a surface energy gradient distribution where the surface energy of the edge region is higher than that of the middle region, this is specifically achieved by using an adjustable power plasma treatment device to perform scanning treatment from the edge of the photovoltaic module towards the center.

[0035] The processing device employs differentiated power modes for different regions of the component. The edge region uses a high-power processing mode, which uses higher energy output to act on the surface of the edge region, causing more thorough physicochemical changes on the surface of the region, such as generating more oxygen-containing polar groups or forming a denser cross-linked layer, thereby effectively improving the surface energy of the edge region and laying the foundation for subsequent enhanced film adhesion and sealing. The middle region uses a low-power processing mode, which moderately improves the surface hydrophilicity and basic adhesion characteristics of the middle region while avoiding excessively high surface energy in this region, which would increase the risk of adhesive residue during subsequent film peeling.

[0036] The scanning speed setting of the adjustable power plasma treatment device is also adapted to the regional power mode. Its scanning speed in the edge region is lower than that in the middle region. The slower scanning speed allows the edge region to fully receive the energy of the high-power plasma, ensuring that the surface energy of the edge region reaches a stable and high level. The faster scanning speed is combined with the low-power treatment in the middle region. Under the premise of controlling the total energy input in the middle region, the surface energy of the middle region is kept within a relatively low and reasonable range. Finally, through the coordinated regulation of the power mode and the scanning speed, a surface energy gradient distribution is achieved in which the surface energy of the edge region of the photovoltaic module is higher than that of the middle region.

[0037] In some embodiments, printing an adhesive layer of a first thickness in the edge region and printing an adhesive layer of a second thickness in the middle region based on the surface energy gradient distribution includes: The adhesive layer of the first thickness and the adhesive layer of the second thickness are formed by a multi-channel precision coating process; the adhesive layer is a modified acrylic pressure-sensitive adhesive, and a silane coupling agent is uniformly dispersed in the adhesive layer.

[0038] Based on the gradient distribution of surface energy in the edge region of the photovoltaic module being higher than that in the middle region, a multi-channel precision coating process is used for adhesive layer printing. This process can precisely control the adhesive layer thickness in the edge region and the middle region by independently adjusting the coating parameters of different channels, ensuring that the edge region forms an adhesive layer of the required first thickness and the middle region forms an adhesive layer of the required second thickness, thus achieving the adaptation of adhesive layer thickness to surface energy gradient.

[0039] The resulting adhesive layer uses a modified acrylic pressure-sensitive adhesive, which possesses excellent tack stability and environmental resistance, meeting the requirements of long-term outdoor use of photovoltaic modules. Its adhesive properties can also be matched to the bonding requirements of different areas. Furthermore, a silane coupling agent is uniformly dispersed in the adhesive layer. This coupling agent forms stronger chemical bonds between the adhesive layer and the photovoltaic module surface, effectively improving the adhesion between the adhesive layer and the module surface, especially enhancing the sealing performance of edge areas, preventing moisture penetration during long-term use, further ensuring module reliability, and providing material support for reducing residual adhesive during subsequent film replacement.

[0040] In some embodiments, applying a first pressure to the edge region and a second pressure to the middle region to match the bonding requirements of different regions includes: A segmented pressing and laminating process is used to apply a film to the surface of a photovoltaic module with an adhesive layer; the ambient temperature remains constant during the pressing and laminating process.

[0041] After preparing the adhesive layers for the edge and middle areas of the photovoltaic module, a segmented pressing and lamination process is required on the module surface with the adhesive layer to match the bonding requirements of different areas. During the pressing process, for the edge areas where enhanced sealing performance is needed, a first pressure is applied to press the adhesive layer, ensuring it fully fills the tiny gaps on the module surface and forms a tightly fitted, sealed structure to meet the waterproofing requirements during long-term use. For the middle areas where the risk of residual adhesive after peeling needs to be reduced, a second pressure, less than the first pressure, is applied. This ensures a stable bond between the adhesive layer and the module surface in the middle area, guaranteeing structural reliability during normal module operation, while preventing excessive pressure from causing excessive deformation or adhesion of the adhesive layer to the surface. This lays the foundation for reducing residual adhesive during subsequent film replacement.

[0042] Because the flowability and curing rate of the adhesive layer are easily affected by temperature fluctuations, unstable ambient temperatures can lead to increased adhesive flow, resulting in adhesive overflow at the edges or excessive penetration in the center. Conversely, lower temperatures may accelerate curing, leading to insufficient adhesion between the adhesive layer and the module surface. A constant ambient temperature ensures that the adhesive layer remains in a stable physicochemical state throughout the bonding process, guaranteeing consistent curing between the edge and center areas. This allows for stable sealing performance at the edges and easy peeling in the center, precisely matching the bonding requirements of different areas and further ensuring the overall performance of the full-color photovoltaic film module and the effectiveness of subsequent low-residue replacement.

[0043] In some embodiments, the method further includes: The surface energy of the photovoltaic module surface is detected over the entire area. If the surface energy gradient distribution on the surface of the photovoltaic module does not meet the preset requirements, the power parameters or scanning speed of the plasma treatment are adjusted until the surface energy gradient distribution meets the surface energy difference requirements between the edge region and the middle region.

[0044] After performing a plasma treatment with a gradual energy change on the surface of the photovoltaic module, to ensure that the resulting surface energy gradient distribution accurately matches the requirements of subsequent adhesive layer printing and low-residue replacement, a comprehensive surface energy measurement of the photovoltaic module surface is necessary. This comprehensive measurement must cover both the edge and center areas of the module, acquiring the actual surface energy values ​​of different regions to determine whether the current surface energy gradient meets the preset functional requirements. If the measurement reveals that the surface energy gradient distribution on the photovoltaic module surface does not meet the preset standard—that is, the surface energy difference between the edge and center areas cannot meet the requirements for subsequent process adaptation—then the relevant parameters of the plasma treatment must be adjusted accordingly.

[0045] The power parameters of the plasma treatment can be adjusted to optimize the high power output value in the edge region or the low power output value in the middle region; the scanning speed of the plasma treatment device can also be adjusted to change the slow scanning speed in the edge region or the fast scanning speed in the middle region. Through repeated adjustments and re-testing, the surface energy gradient distribution on the photovoltaic module surface is kept to meet the surface energy difference requirements between the edge and middle regions. This provides a reliable surface foundation for subsequent adhesive layer printing based on the surface energy gradient distribution, achieving a synergistic effect of waterproof and easy-to-peel properties, thereby ensuring the control effect of residual adhesive rate after the replacement of the full-color photovoltaic film module.

[0046] The following example illustrates the component replacement method provided in this application.

[0047] Step 1: Plasma Gradient Treatment Process Use an adjustable power plasma spray gun (power range 500-1500W) to scan along the edge of the component towards the center; The edge area (200mm from the edge) is processed with 1200W high power, and the middle area (>200mm from the edge) is processed with 800W low power. By controlling the movement speed of the spray gun (0.5 m / min at the edge, 1.5 m / min in the middle), a surface energy gradient distribution is achieved: edge ≥70 dyne / cm, middle ≥50 dyne / cm.

[0048] Step 2: Preparation of Differentiated Adhesive Layer A multi-channel screen printing process is used, with a 30±2μm thick adhesive layer printed on the edge area (200mm from the edge) and a 20±2μm thick adhesive layer printed on the middle area (>200mm from the edge); ensuring that the adhesive strength in the middle area is ≥6N / 25mm and that the adhesive strength in the edge area is ≥10N / 25mm. The adhesive layer material is a modified acrylic pressure-sensitive adhesive with 5% silane coupling agent (KH-560) added to enhance the chemical bonding between the edge area and the glass.

[0049] Step 3: Optimization of lamination and film application process A segmented lamination process is adopted: 0.3MPa pressure is applied to the edge area and 0.15MPa pressure is applied to the middle area.

[0050] Corresponding to the component replacement method described above, this invention also proposes a component replacement device.

Figure 2As shown, it includes: The first processing unit 21 is used to perform plasma treatment with gradually changing energy on the surface of the photovoltaic module from the edge to the center, so that the surface energy of the edge region is higher than that of the middle region on the surface of the photovoltaic module.
