Description

Technical Field

[0001] This invention relates to the field of laminator technology, specifically to a modular laminator, lamination device, and lamination system. Background Technology

[0002] A laminator is a mechanical device that presses multiple layers of material together. It is one of the important pieces of equipment for encapsulating solar cell modules.

[0003] However, existing laminators have the following main drawbacks:

[0004] ① The laminator size is calculated in reverse based on demand and production capacity, resulting in a large number of laminator models. Different manufacturers also have different designs for laminators with the same production capacity, lacking a unified standard. This undoubtedly increases design, procurement and after-sales costs. In order to improve efficiency, the length dimension of the laminator is often increased so that multiple components can be laminated in one lamination chamber at the same time. However, if the component plate shape changes, the number of components that can be laminated in one lamination chamber will change, which will bring about changes in lamination capacity, increasing the uncertainty and instability of capacity and limiting applicability. ② For the laminators corresponding to the current mainstream production capacity, the length dimension of the laminator is often increased to allow multiple components to be laminated simultaneously in one lamination chamber. This results in a large overall size. Furthermore, since there must be a certain interval between adjacent components, the design of the laminator becomes redundant, further increasing the size of the laminator. This leads to difficulties in ensuring vacuum, temperature uniformity, large lamination deformation, high energy consumption, and limited improvement in equipment capacity per unit area. ③ Currently, most laminators on the market are dual-cavity, with some models equipped with triple-cavity cooling. The internal flow method is a chain-connected high-temperature cloth support assembly, meaning that the material is input from the left feed end and output from the right discharge end, using a sequential transmission method. The transmission cycle is close to 1 minute, resulting in a long flow time and efficiency that needs improvement.

[0005] Therefore, providing a modular laminator, lamination device, and lamination system is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the above, the present invention provides a modular laminator, lamination apparatus and lamination system to at least solve one of the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A modular laminator includes a frame, multiple lamination components, a limiting lifting mechanism, multiple reciprocating transmission mechanisms, and a gas pressurization system. The multiple lamination components, arranged sequentially from top to bottom, are installed inside the frame via the limiting lifting mechanism, so that when two adjacent lamination components are pressed together, a single lamination cavity is formed between them. The multiple reciprocating transmission mechanisms are respectively installed around the multiple lamination components. The gas pressurization system is integrated inside the frame and on the sides of the lamination components and communicates with the single lamination cavity.

[0008] Furthermore, the plurality of laminating components are divided into a top laminating component and a plurality of lower laminating components located below the top laminating component. The top laminating component is fixed to the inner top of the frame. The plurality of lower laminating components arranged sequentially from top to bottom are installed inside the frame through the limiting lifting mechanism. The plurality of reciprocating transmission mechanisms are respectively installed around the plurality of lower laminating components.

[0009] Furthermore, the limiting and lifting mechanism includes multiple limiting frames, multiple first limiting blocks, multiple lifting seats, and multiple lifting electric cylinders. The multiple limiting frames are all vertically installed inside the frame body and arranged in a matrix on both sides of the multiple laminating components. There is a gap between the limiting frames and the laminating components. Each limiting frame is provided with multiple second limiting blocks arranged at intervals from top to bottom. The multiple lower laminating components are respectively placed on the second limiting blocks via the first limiting blocks fixed to their sides, so that the top laminating component and its adjacent lower laminating components, as well as adjacent... The two lower laminating components are spaced apart; multiple lifting seats are located inside the frame, and the multiple lifting seats are arranged in a matrix on both sides of the multiple lower laminating components. There is a gap between the lifting seats and the lower laminating components, and the bottom plate of each lifting seat is inserted into the lower laminating component at the bottom; multiple lifting electric cylinders are vertically installed inside the frame and arranged in a matrix on both sides of the multiple lower laminating components. The extension end of the telescopic rod of each lifting electric cylinder is aligned with the top pressure plate of the corresponding lifting seat.

[0010] Furthermore, the plurality of limiting frames are divided into a plurality of left limiting frames and a plurality of right limiting frames, the plurality of first limiting blocks are divided into a plurality of left first limiting blocks and a plurality of right first limiting blocks, and the plurality of second limiting blocks are divided into a plurality of left second limiting blocks and a plurality of right second limiting blocks. The plurality of left first limiting blocks are respectively fixed on the sides of a plurality of laminating components that are spaced apart, and the plurality of right first limiting blocks are respectively fixed on the sides of another plurality of laminating components that are spaced apart. The plurality of left second limiting blocks are respectively fixed vertically at intervals on the left limiting frames and correspond to the positions of the plurality of left first limiting blocks, such that the left first limiting blocks are placed on the left second limiting blocks. The plurality of right second limiting blocks are respectively fixed vertically at intervals on the right limiting frames and correspond to the positions of the plurality of right first limiting blocks, such that the right first limiting blocks are placed on the right second limiting blocks.

[0011] Furthermore, the reciprocating transmission mechanism includes a drive roller seat, a drive roller, a first pressure roller, a driven roller seat, a driven roller, a second pressure roller, and a high-temperature fabric. The drive roller seat and the driven roller seat are respectively fixed at both ends of the laminating assembly. The drive roller, driven by a motor, is mounted on the drive roller seat. The first pressure roller is engaged with the drive roller seat and located obliquely below the drive roller. The driven roller is mounted on the driven roller seat. The second pressure roller is engaged with the driven roller seat and located obliquely below the driven roller. The high-temperature fabric surrounds the drive roller, the first pressure roller, the laminating assembly, the driven roller, and the second pressure roller.

[0012] Furthermore, the driven roller seat includes a seat body, bolts, and a limiting plate. The seat body has a transverse groove and a first longitudinal groove. The shaft end of the driven roller is located in the transverse groove and is slidably connected thereto. The limiting plate is located at the open end of the transverse groove. The bolt is screwed sequentially onto the limiting plate and the shaft end of the driven roller, with the head of the bolt pressing against the limiting plate. The shaft end of the second pressure roller is engaged in the first longitudinal groove. The driving roller seat has a second longitudinal groove, and the shaft end of the first pressure roller is engaged in the second longitudinal groove.

[0013] Furthermore, it also includes multiple insulated roller shutters, and each of the four sides of the frame is provided with slide rails distributed in the vertical direction; the multiple insulated roller shutters are respectively installed on the periphery of the frame, and the door body of each insulated roller shutter is fitted into the corresponding slide rail and slidably connected thereto.

[0014] Furthermore, the frame includes a top cover and a frame body, with the top cover mounted on top of the frame body; the top layer lamination assembly is fixed to the bottom of the top cover.

[0015] A modular lamination apparatus includes multiple modular laminators as described above, with the multiple modular laminators stacked one on top of the other.

[0016] A modular lamination system includes multiple modular lamination devices as described above, wherein the multiple modular lamination devices are arranged sequentially.

[0017] Therefore, the present invention provides a modular laminator, lamination device, and lamination system, which, compared with the prior art, have the following advantages: 1) Improved versatility: The length of the laminator is standardized to the size of a single laminating module, forming a single lamination chamber (each lamination chamber can only laminate one module). The number of laminations is only stacked in the height direction, resulting in fixed and stable production capacity. It is suitable for any module type (meeting the size requirements of the largest existing standard module with the smallest possible laminator size), and is not affected by changes in module type. This improves applicability, reduces design, procurement, installation and after-sales costs, and is easy to maintain. 2) Reliable performance and improved product quality: Due to the reduction in the length of the laminator (smaller size), it is not only easier to process, but also reduces deformation, improves temperature uniformity, reduces vacuum leakage, and achieves a high vacuum level; 3) Fast operating cycle: Saves time compared to traditional long-distance transmission and shortens the overall operating cycle of the lamination zone; 4) High transmission accuracy: The change from cyclic unidirectional transmission to reciprocating transmission results in a leapfrog improvement in repetitive positioning accuracy, which directly translates into significant improvements in product processing consistency, production yield, and overall equipment efficiency. 5) Low energy consumption: Each modular laminator is independently insulated, resulting in low heat loss, fast heating rate, and significantly reduced operating power; 6) Small footprint: The modular laminator occupies an area of ​​about 10 square meters, and the stacked combination of laminators occupies only 1 / 3 of the footprint of a double-layer laminator with the same capacity, and 1 / 2 of the footprint of a multi-layer laminator. 7) High scalability: Modular design allows for flexible stacking and combination based on production capacity, matching any production capacity.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figure 1-7As shown, this invention discloses a modular laminator, including a frame 1, multiple lamination components 2, a limiting lifting mechanism 3, multiple reciprocating transmission mechanisms 4, and a gas pressurization system 5. Multiple lamination components 2, arranged sequentially from top to bottom, are installed inside the frame 1 via the limiting lifting mechanism 3, so that when two adjacent lamination components 2 are pressed together, a single lamination cavity is formed between them. Multiple reciprocating transmission mechanisms 4 are respectively installed around the multiple lamination components 2. The gas pressurization system 5 is integrated inside the frame 1 and on the side of the lamination components 2 and communicates with the single lamination cavity. On one hand, this invention adopts a single-component lamination method, where each lamination cavity can only laminate one component. The dimensions are uniform, the production capacity is determined, and it is applicable to any component board type, unaffected by component board type changes, thus improving applicability and reducing design, procurement, installation, and after-sales costs, while also being easy to maintain. On the other hand, it saves long-distance transmission time, shortens the operating cycle, and improves transmission accuracy. Finally, it significantly reduces the floor space required and improves space utilization.

[0022] Specifically, the structures of the lamination component 2 and the gas pressurization system 5 are the same as those of a fully automatic stacked multilayer laminator disclosed in CN114834138B, and will not be described in detail here.

[0023] Specifically, the multiple laminating components 2 are divided into a top laminating component 21 and multiple lower laminating components 22 located below the top laminating component 21. The top laminating component 21 is fixed to the inner top of the frame 1. In this embodiment, the frame 1 includes a top cover 11 and a frame body 12. The top cover 11 is installed on the top of the frame body 12. The top laminating component 21 is fixed to the bottom of the top cover 11. Multiple lower laminating components 22 arranged sequentially from top to bottom are installed inside the frame 1 through a limiting lifting mechanism 3. Multiple reciprocating transmission mechanisms 4 are respectively arranged around the multiple lower laminating components 22. In this embodiment, there are 4 lower laminating components 22, and correspondingly, there are also 4 reciprocating transmission mechanisms 4.

[0024] Specifically, the limiting and lifting mechanism 3 includes multiple limiting frames 31, multiple first limiting blocks 32, multiple lifting seats 33, and multiple lifting electric cylinders 34. The multiple limiting frames 31 are all vertically installed inside the frame body 1 and arranged in a matrix on both sides of the multiple laminated components 2. There is a gap between the limiting frames 31 and the laminated components 2, meaning the limiting frames 31 do not obstruct the vertical movement of the laminated components 2. Each limiting frame 31 is provided with multiple second limiting blocks 35 arranged at intervals from top to bottom. Multiple lower-layer laminated components 22 are respectively placed on the second limiting blocks 35 via the first limiting blocks 32 fixed to their sides, so that the top-layer laminated component 21 is adjacent to it. The lower layer laminating components 22 are distributed at intervals between adjacent lower layer laminating components 22; multiple lifting seats 33 are located inside the frame 1, and the multiple lifting seats 33 are arranged in a matrix on both sides of the multiple lower layer laminating components 22. There is a gap between the lifting seats 33 and the lower layer laminating components 22, and the bottom plate of each lifting seat 33 is inserted into the lower layer laminating component 22 located at the bottom; multiple lifting electric cylinders 34 are vertically installed inside the frame 1 and arranged in a matrix on both sides of the multiple lower layer laminating components 22. The extension end of the telescopic rod of each lifting electric cylinder 34 is aligned with the top pressure plate of the corresponding lifting seat 33. During operation, the telescopic rod of the lifting cylinder 34 extends, driving the lifting seat 33 to rise. At this time, since the bottom plate of the lifting seat 33 is inserted under the bottommost lower laminating component 22, the bottommost lower laminating component 22 will rise with the lifting seat 33, lifting each lower laminating component 22 layer by layer until the topmost lower laminating component 22 is pressed together with the top laminating component 21. After lamination is completed, the telescopic rod of the lifting cylinder 34 retracts, and each lower laminating component 22 falls down in sequence until the first limiting block 32 on each lower laminating component 22 is placed on the second limiting block 35. Finally, a certain distance is maintained between two adjacent lower laminating components 22, completing the opening of the cover.

[0025] Understandably, when the lifting electric cylinder 34 reaches the target point for opening and closing the cover, it can switch to a slow and smooth mode to resolve the impact defect when opening the cover of the original laminator.

[0026] In some embodiments, a buffer 36 is installed at the position of each second limiting block 35 corresponding to the position of the first limiting block 32. In this embodiment, the buffer 36 is selected as a hydraulic buffer.

[0027] Specifically, the multiple limiting frames 31 are divided into multiple left-side limiting frames and multiple right-side limiting frames; the multiple first limiting blocks 32 are divided into multiple left-side first limiting blocks and multiple right-side first limiting blocks; and the multiple second limiting blocks 35 are divided into multiple left-side second limiting blocks and multiple right-side second limiting blocks. The multiple left-side first limiting blocks are fixed to the sides of multiple laminated components 2 that are spaced apart, and the multiple right-side first limiting blocks are fixed to the sides of other multiple laminated components 2 that are spaced apart. The multiple left-side second limiting blocks are fixed vertically and horizontally on the left-side limiting frames and correspond to the positions of the multiple left-side first limiting blocks, so that the left-side first limiting blocks are placed on the left-side second limiting blocks. The multiple right-side second limiting blocks are fixed vertically and horizontally on the right-side limiting frames and correspond to the positions of the multiple right-side first limiting blocks, so that the right-side first limiting blocks are placed on the right-side second limiting blocks. Through alternating left and right arrangements, the stable support and limiting of each laminated component 2 are achieved.

[0028] Specifically, the reciprocating transmission mechanism 4 includes an active roller seat 41, an active roller 42, a first pressure roller 43, a driven roller seat 44, a driven roller 45, a second pressure roller 46, and a high-temperature fabric. The active roller seat 41 and the driven roller seat 44 are respectively fixed to both ends of the laminating assembly 2. The active roller 42, driven by a motor 47, is mounted on the active roller seat 41. The first pressure roller 43 is engaged with the active roller seat 41 and located diagonally below the active roller 42. The driven roller 45 is mounted on the driven roller seat 44. The second pressure roller 46 is engaged with the driven roller seat 44 and located diagonally below the driven roller 45 to tension the high-temperature fabric. The high-temperature fabric surrounds the active roller 42, the first pressure roller 43, the laminating assembly 2, the driven roller 45, and the second pressure roller 46. The assembly of this invention can input from the active end and output from the active end, realizing reciprocating transmission.

[0029] Specifically, the driven roller seat 44 includes a seat body 441, bolts 442, and a limiting plate 443. The seat body 441 has a transverse groove 4411 and a first longitudinal groove 4412. The shaft end of the driven roller 45 is located in the transverse groove 4411 and is slidably connected thereto. The limiting plate 443 is located at the open end of the transverse groove 4411. The bolts 442 are screwed sequentially onto the limiting plate 443 and the shaft end of the driven roller 45, with the heads of the bolts 442 pressing against the limiting plate 443. The shaft end can move horizontally within the transverse groove 4411 and be fixed in position by bolts 442 and limiting plate 443, so that the front and rear positions of the driven roller 45 can be adjusted to tension the high-temperature cloth; the shaft end of the second pressure roller 46 is engaged in the first longitudinal groove 4412; the driving roller seat 41 has a second longitudinal groove, and the shaft end of the first pressure roller 43 is engaged in the second longitudinal groove, so that the vertical position of the first pressure roller 43 can be adjusted to adjust the tension of the high-temperature cloth.

[0030] To further optimize the technical solution of the present invention, multiple insulated roller shutters 6 are also included. The four sides of the frame are provided with slide rails distributed in the vertical direction. The multiple insulated roller shutters 6 are respectively installed on the periphery of the frame 1, and the door of each insulated roller shutter 6 is fitted into the corresponding slide rail and slidably connected to it. During the lamination process, all-round insulation is achieved, and heat loss is reduced.

[0031] Understandably, a base can be added to the bottom of frame 1 to increase the overall structural stability.

[0032] Example 2: like Figure 8 , 9 As shown, this embodiment discloses a modular lamination device, including multiple modular laminators as described in Embodiment 1. These modular laminators are stacked vertically. In this embodiment, the number of modular laminators is two or three. This invention allows for flexible combinations and can be stacked according to production capacity to meet corresponding production requirements.

[0033] Example 3: like Figure 10 As shown, this embodiment discloses a modular lamination system, including multiple modular lamination devices as described in Embodiment 2, arranged sequentially. This invention can achieve relatively high benefits in terms of performance, reliability, and flexibility at a lower cost.

[0034] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
