Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and more specifically to a lamination tooling and lamination method. Background Technology

[0002] In recent years, photovoltaic power generation has received increasing attention, and photovoltaic power generation systems must be installed on new buildings. Building integrated photovoltaic (BIPV, where PV stands for Photovoltaic) is a technology that integrates solar power generation (photovoltaic) products into buildings. A single building often uses multiple BIPV modules of various lengths and widths.

[0003] Currently, BIPV modules typically consist of a front glass panel and a back glass panel, which are encapsulated with PVB components to form double-glass or triple-glass modules. However, during the encapsulation and lamination process, after the edges of the module are sealed by force, the internal gas is difficult to continue to escape, often resulting in air bubbles at the module edges after lamination. In existing technologies, lamination fixture frames are used to remove corner air bubbles from the modules. Specifically, a closed or detachable lamination fixture frame is placed before lamination, and the module to be laminated is placed inside the frame. The lamination fixture frame enters the laminator along with the module, assisting in supporting the edges of the module and achieving edge buffering during the lamination process. This solves the problem of excessive force on the module edges and high resistance to internal gas escape, facilitating the escape of internal gas.

[0004] However, closed-type lamination tooling frames completely enclose the components, resulting in a large frame structure volume and weight, making turnover and replacement time-consuming and labor-intensive. Demountable lamination tooling frames, on the other hand, require tools to disassemble the tooling frame, adjust the frame size, and reassemble, which is time-consuming and labor-intensive, reduces production efficiency, and also poses the risk of assembly deviations reducing gas exhaust efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing lamination tooling frame, which is time-consuming and labor-intensive and leads to reduced production efficiency, thereby providing a lamination tooling and lamination method.

[0006] This invention provides a lamination fixture, comprising: a plurality of first fixture structures adapted to be distributed and arranged corresponding to protruding positions of an assembly to be laminated, and arranged higher than the assembly to be laminated along the thickness direction, including a first substrate and a first elastic member, the first elastic member being disposed on the first substrate and adapted to buffer impacts along the height direction, a limiting port being provided on the side edge of the first substrate, the limiting port being adapted to accommodate the protruding structure of the assembly to be laminated and being spaced apart from it; and / or, a plurality of second fixture structures adapted to be distributed and arranged corresponding to the side positions of the assembly to be laminated, and arranged higher than the assembly to be laminated along the thickness direction, including a second substrate and a second elastic member, the second elastic member being disposed on the second substrate and adapted to buffer impacts along the height direction, a limiting edge being provided on the second substrate, the limiting edge being arranged adjacent to and spaced apart from the side edge of the assembly to be laminated.

[0007] The first tooling structure further includes a first separating layer, which is made of a non-stick, high-temperature resistant material and is located at the limiting port position, suitable for separating the limiting port and the component to be laminated; and / or, the second tooling structure further includes a second separating layer, which is made of a non-stick, high-temperature resistant material and is located at the limiting edge position, suitable for separating the limiting edge and the component to be laminated.

[0008] The length of the first substrate along the conveying direction of the assembly to be laminated is set to L1, 150mm≤L1≤700mm; and / or, the length of the second substrate along the conveying direction of the assembly to be laminated is set to L2, 150mm≤L2≤700mm.

[0009] The first elastic element is disposed adjacent to the limiting port, with a spacing of L3, 0≤L3≤5mm; and / or, the second elastic element is disposed adjacent to the limiting edge, with a spacing of L4, 0≤L4≤5mm.

[0010] The first elastic element and the second elastic element are identically configured, including several elastic structural strips stacked along the thickness direction and connected to each other.

[0011] The first partition layer extends along the position of the limiting port and is disposed on the upper and lower sides of the first substrate, and / or the second partition layer extends along the position of the limiting edge and is disposed on the upper and lower sides of the second substrate.

[0012] The first separator layer is set to extend along the limiting port toward the inner side of the first substrate by a distance of L5, where 5mm ≤ L5 ≤ 20mm; and / or, the second separator layer is set to extend along the limiting edge toward the inner side of the second substrate by a distance of L6, where 5mm ≤ L6 ≤ 20mm.

[0013] The assembly to be laminated includes: at least one component to be laminated, arranged in a single, single column or array, and several components to be laminated arranged in a single column or array are arranged at uniform intervals.

[0014] A plurality of components to be laminated are arranged along the side of the component to be laminated, and the extension line of the gap between adjacent components to be laminated passes through the limiting edge of the second tooling structure.

[0015] The present invention also provides a lamination method, comprising: arranging and placing components to be laminated; placing a plurality of first tooling structures and / or a plurality of second tooling structures corresponding to the components to be laminated; and controlling a lamination device to laminate the components to be laminated and the lamination tooling.

[0016] The assembly to be laminated includes: at least one component to be laminated, arranged in a single, single column or array, and several components arranged in a single column or array are evenly spaced, with the thickness of the component to be laminated set as H.

[0017] A plurality of components to be laminated are arranged along the side of the component to be laminated, and the extension line of the gap between adjacent components to be laminated passes through the limiting edge of the second tooling structure.

[0018] set up:

[0019] The lamination temperature is set to T1, 140 + (H - 15) × 0.6℃ ≤ T1 ≤ 140 + (H + 5) × 0.6℃; the vacuuming time is t0, 15 + (H - 15) × 0.5min ≤ t0 ≤ 15 + (H + 5) × 0.5min; the lamination time for the first lamination is set to t1, 5min ≤ t1 ≤ 10min, and the pressure for the first lamination is set to P1, 20kPa ≤ P1 ≤ 40kPa; the lamination time for the second lamination is set to t2, 10 + (H - 15) × 0.8min ≤ t2 ≤ 10 + (H + 5) × 0.8min, and the pressure for the second lamination is set to P2, 50kPa ≤ P2 ≤ 100kPa.

[0020] After the step "control the lamination device to laminate the components to be laminated and the lamination tooling", the method further includes: setting up a high-pressure space to accommodate the components to be laminated and performing auxiliary lamination;

[0021] Corresponding settings: Lamination temperature is set to T2, 140+(H-15)×0.6℃≤T2≤140+(H+5)×0.6℃; Vacuuming time is set to t3, 15+(H-15)×0.5min≤t3≤15+(H+5)×0.5min; Lamination time 1 is set to t4, 2min≤t4≤6min; Lamination pressure 1 is set to P3, 20kPa≤P3≤40kPa; Lamination time 2 is set to t5, 2min≤t5≤7min; Lamination pressure 2 is set to P4, 50kPa≤P4≤100kPa.

[0022] The technical solution of this invention has the following advantages:

[0023] 1. The present invention provides a lamination fixture, comprising: a plurality of first fixture structures adapted to be distributed and arranged corresponding to protruding positions of an assembly to be laminated, and arranged higher than the assembly to be laminated along the thickness direction, including a first substrate and a first elastic member, the first elastic member being disposed on the first substrate and adapted to buffer impacts along the height direction, a limiting port being provided on the side edge of the first substrate, the limiting port being adapted to accommodate the protruding structure of the assembly to be laminated and being spaced apart from it; and / or, a plurality of second fixture structures adapted to be distributed and arranged corresponding to the side positions of the assembly to be laminated, and arranged higher than the assembly to be laminated along the thickness direction, including a second substrate and a second elastic member, the second elastic member being disposed on the second substrate and adapted to buffer impacts along the height direction, a limiting edge being provided on the second substrate, the limiting edge being arranged adjacent to and spaced apart from the side edge of the assembly to be laminated.

[0024] By setting the elastic element on the substrate, when the laminating process of the laminator is started, since the tooling structure along the thickness direction is higher than the component to be laminated, it can contact the laminating structure first, and buffer the protruding corner edges and / or side edges of the component to be laminated accordingly, slowing down the lamination process at the corresponding positions, and ensuring that the component to be laminated can complete the edge closure after the internal gas is vented through the corner edge or side edge.

[0025] Furthermore, by selectively setting the first and second tooling structures to correspond to the protruding and side portions of the component to be laminated, respectively, the need to vent the gas inside the component to be laminated can be met, the tooling structure can be reduced in size and weight, making it easier for operators to transport and use. In addition, it does not require disassembly and assembly, making it convenient to use and helping to improve production efficiency and modular manufacturing and use. It can effectively overcome the shortcomings of existing lamination tooling frames, such as being time-consuming and labor-intensive to use, resulting in low production efficiency.

[0026] 2. The present invention provides a lamination fixture, wherein the first fixture structure further includes a first separator layer, which is made of a non-stick, high-temperature resistant material and is disposed at the limiting port position, suitable for separating the limiting port and the component to be laminated; and / or, the second fixture structure further includes a second separator layer, which is made of a non-stick, high-temperature resistant material and is disposed at the limiting edge position, suitable for separating the limiting edge and the component to be laminated.

[0027] By setting a separation layer, the limiting port and limiting edge can be separated from the component to be laminated, preventing excessive molten adhesive from the edge of the component to be laminated from adhering to the tooling structure during the lamination or conveying process.

[0028] 3. The present invention provides a lamination fixture, wherein the length of the first substrate along the conveying direction of the assembly to be laminated is L1, 150mm≤L1≤700mm; and / or, the length of the second substrate along the conveying direction of the assembly to be laminated is L2, 150mm≤L2≤700mm.

[0029] By limiting the length range of the first and second substrates along the conveying direction of the assembly to be laminated, with the lower limit being greater than or equal to 150mm, the length of the first and second substrates is greater than the spacing between the rollers on the commonly used conveying track of the laminator, ensuring that the substrates are conveyed smoothly on the automatic laminator line without falling off. The upper limit is less than or equal to 700mm, which reduces the structural volume of the first or second substrate, avoids overlap of adjacent tooling structures, and reduces the structural weight of the first and second substrates, making it easier for operators to transport and use them.

[0030] 4. The present invention provides a lamination tooling, wherein the first elastic element is disposed adjacent to the limiting port, and the distance between them is set to L3, 0≤L3≤5mm; and / or, the second elastic element is disposed adjacent to the limiting edge, and the distance between them is set to L4, 0≤L4≤5mm.

[0031] This setting of the spacing between each elastic element and the limiting port or limiting edge serves two purposes: firstly, it prevents the elastic elements from exceeding the setting range of the substrate and coming into contact with or sticking to the laminated component under test; secondly, the close proximity of each elastic element to the limiting port or limiting edge facilitates effective buffering of the corresponding parts.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figure 1 - Figure 5As shown, this embodiment provides a lamination fixture, including: a plurality of first fixture structures 1 and a plurality of second fixture structures 2. As a possible implementation, only one of the first fixture structures 1 and the second fixture structure 2 may be provided.

[0045] If the first tooling structure 1 is suitable for the distribution of the protruding positions of the component to be laminated 3, and the protruding positions correspond to the shape selection of the component to be laminated 3, in this embodiment, the component to be laminated 3 is rectangularly distributed, and the protruding positions of the component to be laminated 3 are specifically the corner positions of the component to be laminated 3. The first tooling structure 1 is set higher than the component to be laminated 3 along the thickness direction, and the specific height exceeding the height can be adjusted adaptively as needed.

[0046] The first tooling structure 1 includes a first substrate 11 and a first elastic member 12. The first elastic member 12 is disposed on the first substrate 11 and is suitable for buffering impacts along the height direction. Specifically, the first substrate 11 is a flat plate structure. The specific shape of the flat plate is not limited, but it is preferably partially rectangular. Since a limiting port 13 is provided at one corner, the first substrate 11 is "L" shaped. In this embodiment, the limiting port 13 is a right-angle opening, which is suitable for accommodating the corner of the component 3 to be laminated. The limiting port 13 and the component 3 to be laminated are spaced apart.

[0047] The second tooling structure 2 is adapted to be distributed and positioned corresponding to the side of the component 3 to be laminated, and is positioned higher than the component 3 to be laminated along the thickness direction. It includes a second substrate 21 and a second elastic member 22. The second elastic member 22 is disposed on the second substrate 21 and is adapted to buffer impacts along the height direction. Specifically, the second substrate 21 is also arranged in a flat plate structure. The specific shape of the flat plate is not limited, but it is preferably arranged in a partially rectangular plate shape. A limiting edge 23 is provided on the second substrate 21. In this embodiment, the limiting edge 23 is the long side of one side of the second substrate 21, and this long side is arranged adjacent to and spaced apart from the side of the component 3 to be laminated.

[0048] In this embodiment, the distance between the limiting port 13 and the limiting edge 23 and the component 3 to be laminated ranges from 10mm to 50mm, preferably from 15mm to 30mm, and can specifically be 10mm, 15mm, 25mm, 30mm, 45mm, 50mm, etc. Furthermore, the thickness of the first substrate 11 and the second substrate 21 ranges from 1mm to 7mm, preferably from 2mm to 5mm, and can be 1mm, 2mm, 3mm, 5mm, or 7mm. The first elastic member 12 and the second elastic member 22 are respectively disposed on the upper side of the first substrate 11 and the upper side of the second substrate 21, and the top of each elastic member extends beyond the height of the component 3 to be laminated by 1mm to 8mm, preferably from 2mm to 6mm. Specifically, it can be 1mm, 2mm, 5mm, 6mm, and 8mm, etc. In this embodiment, when the elastic deformation amplitude of the elastic element is at its maximum under the high temperature environment and one atmosphere of pressure of the laminator, the height of the substrate superimposed on the elastic element is still greater than or equal to the thickness of the lamination assembly 3. Preferably, under the high temperature environment and one atmosphere of pressure of the laminator, the elastic deformation amplitude of the elastic element is less than 1 mm.

[0049] By setting the elastic element on the substrate, when the laminating process of the laminator is started, since the tooling structure along the thickness direction is set higher than the component 3 to be laminated, it can contact the laminating structure first, and buffer the protruding corner edge and / or side edge of the component 3 to be laminated respectively, slowing down the lamination process at the corresponding position, and ensuring that the component 3 to be laminated can complete the edge closure after the internal gas is vented through the corner edge or side edge.

[0050] Furthermore, by selectively setting the first tooling structure 1 and the second tooling structure 2 to correspond to the protruding part and the side part of the component to be laminated 3 respectively, it can not only meet the need to vent the gas inside the component to be laminated 3, but also reduce the size and weight of the tooling structure, making it easier for operators to transport and use. In addition, it does not require disassembly and assembly, making it convenient to use and helping to improve production efficiency and modular manufacturing and use. It can effectively overcome the defects of existing lamination tooling frames, such as being time-consuming and labor-intensive to use, resulting in low production efficiency.

[0051] In this embodiment, the first tooling structure 1 further includes a first separating layer 14, made of a non-adhesive, high-temperature resistant material, located at the limiting port 13, suitable for separating the limiting port 13 and the component 3 to be laminated. The second tooling structure 2 further includes a second separating layer 24, made of a non-adhesive, high-temperature resistant material, located at the limiting edge 23, suitable for separating the limiting edge 23 and the component 3 to be laminated. In this embodiment, "non-adhesive material" means that the material is non-adhesive, does not easily adhere to other substances such as sol, metal, etc., and is easy to wash and remove dirt from its surface. By setting the separating layer, the limiting port 13 and the limiting edge 23 can be separated from the component 3 to be laminated, preventing excessive molten adhesive on the edge of the component 3 to be laminated from adhering to the tooling structure during the lamination or conveying process.

[0052] As a variable implementation, when only one of the first tooling structure 1 and the second tooling structure 2 is provided, a corresponding first partition layer 14 or second partition layer 24 is provided on it.

[0053] Specifically, the first separator layer 14 extends along the limiting port 13 and is disposed on the upper and lower sides of the first substrate 11, and the second separator layer 24 extends along the limiting edge 23 and is disposed on the upper and lower sides of the second substrate 21. This arrangement can prevent excessive molten adhesive from falling onto the tooling structure at the edge of the component 3 to be laminated, thus avoiding adhesion between the substrate and the conveying structure when it flows to the lower side of the substrate. As an alternative implementation, the first separator layer 14 can be disposed only on the edge of the limiting port 13, and the second separator layer 24 can be disposed only on the edge of the limiting edge 23.

[0054] Furthermore, the first partition layer 14 is configured to extend along the limiting port 13 toward the inner side of the first substrate 11 by a distance L5, where 5mm ≤ L5 ≤ 20mm, and the second partition layer 24 is configured to extend along the limiting edge 23 toward the inner side of the second substrate 21 by a distance L6, where 5mm ≤ L6 ≤ 20mm. In this embodiment, the extension range of the first partition layer 14 and the second partition layer 24 toward the corresponding substrate is preferably 10mm-20mm, specifically 5mm, 10mm, 15mm, or 20mm.

[0055] In this embodiment, the first separator layer 14 and the second separator layer 24 are made of polytetrafluoroethylene material, specifically Teflon high-temperature cloth. As an alternative implementation, they can also be made of ceramic material.

[0056] In this embodiment, the length of the first substrate 11 along the conveying direction of the assembly to be laminated 3 is set to L1, where 150mm ≤ L1 ≤ 700mm; the length of the second substrate 21 along the conveying direction of the assembly to be laminated 3 is set to L2, where 150mm ≤ L2 ≤ 700mm. Preferably, the length and width of the first substrate 11 are both 300mm-600mm, and the specific values ​​can be 150mm, 200mm, 300mm, 350mm, 600mm, 650mm, or 700mm, etc. Preferably, the length of the second substrate 21 is 300mm-600mm, and the width is between 100mm-300mm, and the specific values ​​of its length can be 150mm, 200mm, 300mm, 350mm, 600mm, 650mm, or 700mm; the specific values ​​of its width can be 100mm, 150mm, 200mm, 300mm, etc.

[0057] By limiting the length range of the first substrate 11 and the second substrate 21 along the conveying direction of the assembly to be laminated 3, with a lower limit greater than or equal to 150mm, the length of the first substrate 11 and the second substrate 21 is greater than the spacing between the rollers on the commonly used conveyor track of the laminator, ensuring that the substrates are smoothly conveyed on the automatic laminator line without falling off. The upper limit is less than or equal to 700mm, which reduces the structural volume of the first substrate 11 or the second substrate 21, avoids overlap of adjacent tooling structures, and reduces the structural weight of the first substrate 11 and the second substrate 21, facilitating transport and use by operators. Generally, the length of the first substrate 11 and the second substrate 21 can be set to be greater than twice the spacing between the rollers on the commonly used conveyor track of the laminator. Correspondingly, the length and width of the first substrate 11 are preferably greater than 300mm, and the length of the second substrate is greater than 300mm. When the substrate is moved forward to the point where its center of gravity is placed on the edge of the rear track roller, the front end of the substrate needs to be in contact with the front track roller to better ensure smooth transmission. In addition, the substrate is a homogeneous plate, and the substrate length needs to be greater than or equal to twice the commonly used track roller spacing, corresponding to a substrate length greater than 300mm.

[0058] In this embodiment, the first substrate 11 and the second substrate 21 are uniformly made of a high-temperature resistant metal material. The metal substrate structure provides better heat dissipation and allows for reuse after a short cooling period following lamination, resulting in a higher turnover rate. Furthermore, it is preferable that the weight of the first substrate 11 is slightly greater than 500 grams, and the weight of the second substrate 21 is slightly greater than 400 grams.

[0059] Specifically, the first substrate 11 and the second substrate 21 can be metals or alloys such as aluminum, iron, and copper, preferably aluminum or aluminum alloy products, so that the structure is lighter.

[0060] As an alternative implementation, the first substrate 11 and the second substrate 21 may be made of only one of a high-temperature resistant metallic material. As an alternative implementation, both the first substrate 11 and the second substrate 21, or one of them, may be made of a rigid, high-temperature resistant non-metallic material, such as a high-temperature resistant ceramic material or a high-temperature resistant fiber material.

[0061] In this embodiment, the first elastic element 12 is disposed adjacent to the limiting port 13 with a spacing of L3, where 0 ≤ L3 ≤ 5 mm. The second elastic element 22 is disposed adjacent to the limiting edge 23 with a spacing of L4, where 0 ≤ L4 ≤ 5 mm. Preferably, L3 and L4 range from 0 mm to 3 mm, specifically 0, 1 mm, 3 mm, or 5 mm.

[0062] This setting of the spacing between each elastic element and the limiting port 13 or the limiting edge 23 serves two purposes: firstly, it prevents the elastic elements from exceeding the setting range of the substrate and coming into contact with or sticking to the laminated component under test; secondly, the close proximity of each elastic element to the limiting port 13 or the limiting edge 23 facilitates effective buffering at the corresponding locations.

[0063] In this embodiment, the first elastic element 12 and the second elastic element 22 are configured as silicone pads. Specifically, they are made of high-temperature silicone rubber. In this embodiment, the first elastic element 12 is shaped to conform to the limiting port 13, and the first elastic element 12 includes two elongated silicone pads, which are respectively placed inside the limiting port 13. The second elastic element 22 is an elongated silicone pad, which is disposed in the middle of the upper limit edge 23 of the second substrate 21. As an alternative implementation, either or both of the first elastic element 12 and the second elastic element 22 may be configured as non-silicone pads, such as uniformly distributed micro springs.

[0064] The first elastic element 12 and the second elastic element 22 are identical in shape. Specifically, identical in shape means that they have the same structural form, both including several elastic structural strips stacked and connected to each other along the thickness direction. In this embodiment, both the first elastic element 12 and the second elastic element 22 are elongated silicone pads, and the silicone pads may include a single elastic structural strip or multiple stacked silicone elastic structural strips. As an alternative implementation, the first elastic element 12 may also be an "L"-shaped silicone pad, with its elastic structural strips also arranged in an "L" shape.

[0065] This embodiment also provides a lamination method, including: S1. arranging and placing the components 3 to be laminated; S2. placing a plurality of first tooling structures 1 and a plurality of second tooling structures 2 corresponding to the components 3 to be laminated; S3. controlling the lamination device to laminate the components 3 to be laminated and the lamination tooling. As a variable implementation, only a plurality of first tooling structures 1 or a plurality of second tooling structures 2 may be placed corresponding to the components 3 to be laminated.

[0066] In this embodiment, the assembly to be laminated 3 includes a plurality of laminar components 31 arranged in a square array. The laminar components 31 are evenly spaced, with a spacing of 8mm-35mm, preferably 10mm-20mm, and specifically 8mm, 10mm, 15mm, 20mm, 25mm, 35mm, etc. This arrangement can prevent the laminar components 31 from sticking together during the lamination process and ensure the expulsion of air bubbles. The overall assembly to be laminated 3 is preferably arranged in a rectangular square array. As a variable implementation, the assembly to be laminated 3 includes a single laminar component 31 or a plurality of laminar components 31 arranged in a single row. Specifically, the laminar components 31 are BIPV components and are arranged in a rectangular plate shape. As a variable implementation, the laminar components 31 can also be circular, rhomboid, or irregular in shape.

[0067] In this embodiment, the matrix-arranged lamination components 3 have a plurality of lamination parts 31 arranged along their side. Specifically, the extension line of the gap between adjacent lamination parts 31 passes through the limiting edge 23 of the second tooling structure 2. Preferably, the extension line of the gap between adjacent lamination parts 31 is collinear with the axis of symmetry of the second tooling structure 2. This arrangement can effectively distribute the pressure on the edges of adjacent lamination parts 31 and avoid stress concentration.

[0068] In addition, after step S3, the process includes: after lamination is completed, removing the first tooling structure 1 and the second tooling structure 2, and returning to step S2. Specifically, after lamination is completed, the lamination tooling stays on the cooling track of the laminator unloading section for a preset time. The preset time can be adjusted as needed. After the lamination tooling cools down, it is removed and placed on a shelf or manually transferred to the laminator for placement of the next component 3 to be laminated.

[0069] Since the component to be laminated 31 is a BIPV module, the photovoltaic module lamination can be divided into two main stages: the vacuuming stage and the lamination stage. When the laminator is in a sealed state, the silicone plate on the top cover divides the laminator into an upper chamber and a lower chamber. The lower chamber is equipped with a heating plate, and the upper chamber is a rectangular space with a relatively small thickness.

[0070] During the vacuuming stage, both the upper and lower chambers are evacuated simultaneously. In the sealed, vacuum-controlled lower chamber, the lower heating plate heats and melts the adhesive film, removing the gas inside the module and placing it under no pressure. During the lamination stage, the upper chamber is filled with gas while the lower chamber remains a vacuum. Depending on the process settings, there may be two or three different filling pressures and times, referred to as lamination one, lamination two, or lamination three, etc.

[0071] In this embodiment, during the lamination process, the lamination parameters for PVB (polyvinyl butyral) or POE (polyolefin thermoplastic elastomer) can be set according to the thickness H of the part to be laminated 31. The thickness H can be selected as needed. In this embodiment, 5mm ≤ H ≤ 40mm. Preferably, the value of H is in the range of 8mm-35mm, specifically 8mm, 10mm, 15mm, 20mm, 25mm, 35mm, etc. As an alternative implementation, H can be greater than 40mm or less than 5mm.

[0072] Furthermore, after the lamination stage, a high-pressure space can be set up to accommodate the component 3 to be laminated and to perform auxiliary lamination. Specifically, the high-pressure space is the inner cavity of an autoclave, or it can be other high-pressure environments. This setup can reduce the lamination stage time and improve the processing efficiency of the laminator.

[0073] In this implementation, when the lamination parameters for the corresponding lamination stage of the autoclave are not set, they can be set as follows:

[0074] The lamination temperature is set to T1, where 140 + (H - 15) × 0.6℃ ≤ T1 ≤ 140 + (H + 5) × 0.6℃. For example, T1 could be 135 + (H - 8) × 0.6℃. The vacuuming time is set to t0, where 15 + (H - 15) × 0.5min ≤ t0 ≤ 15 + (H + 5) × 0.5min. For example, t0 could be 15 + (H - 5) × 0.5min.

[0075] Preferably, the lamination time is set to t1, where 5 min ≤ t1 ≤ 10 min, specifically 5 min, 7 min, or 10 min, etc., and the lamination pressure is set to P1, where 20 kPa ≤ P1 ≤ 40 kPa, specifically 20 kPa, 30 kPa, or 40 kPa, etc. As an alternative implementation, t1 can be less than 5 min or greater than 10 min, and P1 can be less than 20 kPa or greater than 40 kPa.

[0076] Furthermore, the lamination time for the second lamination is set to t2, where 10 + (H - 15) × 0.8 min ≤ t2 ≤ 10 + (H + 5) × 0.8 min. For example, t2 could be 10 + (H - 5) × 0.8 min. The pressure for the second lamination is set to P2, where 50 kPa ≤ P2 ≤ 100 kPa. The specific value can be 50 kPa, 60 kPa, 80 kPa, or 100 kPa, etc.

[0077] When setting up an autoclave, the lamination parameters for the corresponding lamination stage can be set as follows:

[0078] The lamination temperature is set to T2, where 140 + (H - 15) × 0.6℃ ≤ T2 ≤ 140 + (H + 5) × 0.6℃. For example, T2 could be 140 + (H - 5) × 0.6℃. The vacuuming time is set to t3, where 15 + (H - 15) × 0.5min ≤ t3 ≤ 15 + (H + 5) × 0.5min. For example, t3 could be 15 + (H - 5) × 0.5min.

[0079] The lamination time for the first lamination is set to t4, where 2 min ≤ t4 ≤ 6 min, preferably 3 mm to 5 min, and can be 2 mm, 3 mm, 4 mm, 5 mm, or 6 mm. The pressure for the first lamination is set to P3, where 20 kPa ≤ P3 ≤ 40 kPa, and can be 20 kPa, 30 kPa, or 40 kPa, etc. The lamination time for the second lamination is set to t5, where 2 min ≤ t5 ≤ 7 min, for example, 5 min. The pressure for the second lamination is set to P4, where 50 kPa ≤ P4 ≤ 100 kPa, and can be 50 kPa, 60 kPa, 80 kPa, or 100 kPa, etc.

[0080] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
