Description

Technical Field

[0001] This utility model relates to the field of laminating technology, and in particular to a photovoltaic module laminating machine. Background Technology

[0002] Traditional photovoltaic module laminators typically use fixed positioning structures to position components such as glass, EVA, and backsheets during the lamination process. However, under the high temperature and pressure lamination environment, the materials in each layer of the photovoltaic module are prone to slight displacement due to differences in their coefficients of thermal expansion. Fixed positioning structures restrict the free expansion and contraction of these materials, leading to stress concentration within the module and causing defects such as microcracks, bubbles, or delamination, thus reducing the yield of the finished product. Furthermore, traditional positioning components are prone to hard collisions with the module when the laminating cover is pressed down, resulting in decreased positioning accuracy or module damage. Existing equipment generally lacks the ability to dynamically adjust the positioning mechanism, and the lamination table height is fixed, making it difficult to adapt to the high-precision lamination requirements of modules with different thicknesses. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that the fixed positioning structure in the prior art restricts the free expansion and contraction of materials, resulting in stress concentration inside the component, causing defects such as microcracks, bubbles or delamination, and reducing the yield of finished products, a photovoltaic module laminator is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a photovoltaic module laminator, including a frame and a raw material conveyor belt, a transfer mechanism and a lamination mechanism installed on the frame. The raw material conveyor belt is used to transport the components of the photovoltaic module. The transfer mechanism is used to transfer the components of the photovoltaic module on the raw material conveyor belt to the lamination mechanism. The lamination mechanism is used to laminate the components of the photovoltaic module together. The lamination mechanism includes a lamination table and mutually cooperating positioning components are installed on the side of the lamination table. The laminating table has positioning cavities for accommodating positioning components. Each positioning cavity corresponds to a positioning component, and the positioning component is arranged within its corresponding positioning cavity. The positioning component includes a first elastic element, a second elastic element, a moving block, and a positioning cover. Both the first elastic element and the moving block are arranged within the positioning cavity, with one end of the first elastic element connected to the positioning cavity and the other end connected to the moving block. The moving block is located between the first elastic element and the middle of the laminating table. The positioning cover and the moving block are slidably connected. The second elastic element is arranged between the positioning cover and the moving block. Through the dual buffer design of the first and second elastic elements, the positioning cover can dynamically expand and contract with the thermal expansion of the module, eliminating stress damage caused by rigid constraints and significantly reducing microcracks and delamination. The positioning cavity corresponds to the positioning component, and the sliding connection between the moving block and the positioning cover ensures that the positioning cover can move elastically when the laminating cover is pressed down, maintaining the positioning of the photovoltaic module components during the lamination process.

[0005] To address the issue of motion interference between the laminator and the positioning components, which affects positioning accuracy, the lamination mechanism further includes a laminator and a lamination drive. The lamination table is arranged on the frame, the lamination drive is fixedly connected to the frame, and the output end of the lamination drive is driven by the laminator. The lamination drive provides power for the laminator to move away from or towards the laminator, and the laminator is located above the lamination table.

[0006] To address the issue of the positioning cover compressing the first elastic element and reducing its lifespan when it contracts, the system further includes a positioning cover that encloses the moving block, with a clearance groove on the positioning cover to avoid the first elastic element.

[0007] To address the issue of unstable sliding between the positioning cover and the moving block, which leads to component misalignment, the system further includes a guide post installed inside the positioning cover, which passes through the moving block, and a second elastic element fitted onto the guide post.

[0008] To address the issue of scratches caused by friction between the laminating cover and the positioning cover during pressing, a further improvement is made by installing rollers on the top surface of the positioning cover.

[0009] To address the issue of a fixed laminar flow table height that cannot accommodate components of different thicknesses, a further laminar flow mechanism is included, comprising a laminar flow lifting and adjusting drive component. The laminar flow lifting and adjusting drive component is fixedly connected to the frame, and its output end is connected to the laminar flow table via a transmission connection. The laminar flow lifting and adjusting drive component is used to provide power for the lifting and lowering of the laminar flow table.

[0010] To address the issues of low component transfer efficiency and easy positioning deviation, the transfer mechanism further includes a transfer lateral drive, a transfer lifting drive, and a transfer gripper. The transfer lateral drive is fixedly connected to the frame, the output end of the transfer lateral drive is connected to the transfer lifting drive, and the output end of the transfer lifting drive is connected to the transfer gripper.

[0011] To address the issue of manual handling of finished products affecting production line continuity, the laminator further includes a finished product conveyor belt, which is fixedly connected to the frame.

[0012] The beneficial effects of this utility model are as follows: The photovoltaic module laminator provided by this utility model, through the dual buffer design of the first elastic element and the second elastic element, allows the positioning cover to dynamically expand and contract with the thermal expansion of the module, eliminating stress damage caused by rigid constraints and significantly reducing microcracks and delamination; the positioning cavity corresponds one-to-one with the positioning component, and combined with the sliding connection between the moving block and the positioning cover, it ensures that the positioning cover can move elastically when the laminating cover is pressed down, maintaining the positioning of the photovoltaic module components during the lamination process.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1 This is a schematic diagram of the structure of the present invention. A photovoltaic module laminator includes a frame 1 and a raw material conveyor belt 2, a transfer mechanism 3 and a lamination mechanism 4 installed on the frame 1. The raw material conveyor belt 2 is used to transport the components of the photovoltaic module. The transfer mechanism 3 is used to transfer the components of the photovoltaic module on the raw material conveyor belt 2 to the lamination mechanism 4. The lamination mechanism 4 is used to laminate the components of the photovoltaic module together. The lamination mechanism 4 includes a lamination table 41 and positioning components 5 that cooperate with each other are installed on the side of the lamination table 41. like Figure 1 , 2As shown in Figure 3, the laminating table 41 has a positioning cavity 411 for accommodating the positioning assembly 5. Each positioning cavity 411 corresponds to a positioning assembly 5, and the positioning assembly 5 is arranged within its corresponding positioning cavity 411. The positioning assembly 5 includes a first elastic element 51, a second elastic element 52, a moving block 53, and a positioning cover 54. The first elastic element 51 and the second elastic element 52 are springs. Both the first elastic element 51 and the moving block 53 are arranged within the positioning cavity 411, with one end of the first elastic element 51 connected to the positioning cavity 411 and the other end connected to the moving block 53. The moving block 53 is located within the first elastic element 51. Between component 51 and the middle of the laminating table 41, the positioning cover 54 and the moving block 53 are slidably connected. The second elastic element 52 is arranged between the positioning cover 54 and the moving block 53. Through the dual buffer design of the first elastic element 51 and the second elastic element 52, the positioning cover 54 can dynamically expand and contract with the thermal expansion of the component, eliminating stress damage caused by rigid constraints and significantly reducing microcracks and delamination. The positioning cavity 411 corresponds one-to-one with the positioning component 5. Combined with the sliding connection between the moving block 53 and the positioning cover 54, it ensures that the positioning cover 54 can move elastically when the laminating cover 42 is pressed down, maintaining the positioning of the photovoltaic module components during the lamination process.

[0018] The lamination mechanism 4 includes a lamination hood 42 and a lamination drive 43. The lamination drive 43 can be a hydraulic cylinder. The lamination table 41 is arranged on the frame 1. The lamination drive 43 is fixedly connected to the frame 1. The output end of the lamination drive 43 is connected to the lamination hood 42. The lamination drive 43 is used to provide power to move the lamination hood 42 away from or closer to it. The lamination hood 42 is located above the lamination table 41. The lamination hood 42 has an independent drive design to avoid interference with the positioning component 5 and to ensure uniform lamination pressure.

[0019] The positioning cover 54 covers the moving block 53. The positioning cover 54 has a relief groove 543 for avoiding the first elastic element 51. The relief groove 543 provides deformation space for the first elastic element 51 and avoids mechanical interference.

[0020] A guide post 541 is installed inside the positioning cover 54. The guide post 541 passes through the moving block 53. The second elastic element 52 is sleeved on the guide post 541. The guide post 541 guides the moving block 53 to slide linearly. The second elastic element 52 sleeved on the guide post 541 enhances stability and improves positioning accuracy.

[0021] like Figure 1 , 2 As shown in Figure 3, a roller 542 is installed on the top surface of the positioning cover 54. The roller 542 converts sliding friction into rolling friction, reducing wear and ensuring smooth downward pressure.

[0022] like Figure 1 , 2As shown in Figure 3, the lamination mechanism 4 includes a lamination lifting and adjusting drive 44, which is fixedly connected to the frame 1. The output end of the lamination lifting and adjusting drive 44 is connected to the lamination table 41. The lamination lifting and adjusting drive 44 is used to provide power for the lifting and lowering of the lamination table 41. The lamination lifting and adjusting drive 44 can be a hydraulic cylinder. The lamination lifting and adjusting drive 44 enables flexible adjustment of the height of the lamination table 41, expanding the applicability of the equipment.

[0023] The transfer mechanism 3 includes a transfer lateral drive 31, a transfer lifting drive 32, and a transfer gripper 33. The transfer lateral drive 31 is fixedly connected to the frame 1. The output end of the transfer lateral drive 31 is connected to the transfer lifting drive 32. The output end of the transfer lifting drive 32 is connected to the transfer gripper 33. The three-axis drive of the transfer mechanism 3 enables precise gripping and rapid transfer, improving the degree of automation.

[0024] The laminator also includes a finished product conveyor belt 6, which is fixedly connected to the frame 1. The finished product conveyor belt 6 automatically receives the components output by the transfer mechanism, forming a complete production closed loop.

[0025] Working process: The raw material conveyor belt 2 transports components such as glass, EVA, and back panel to the designated position. The gripper 33 of the transfer mechanism 3 grabs the component and moves it precisely on the laminating table 41 through the transfer lateral drive 31 and the transfer lifting drive 32. The positioning cover 54 automatically presses against the edge of the component under the action of the first elastic element 51 to complete the initial positioning. The lamination drive 43 drives the lamination cover 42 to press down, and the positioning cover 54 descends after being pressed to adapt to the lamination. After lamination, the component will deform to a certain extent and shrink smoothly through the roller 542. The moving block 53 slides along the guide post 541 and compresses the first elastic element 51. The lamination cover 42 completely covers the component and applies heat pressure. During this period, the thermal expansion of the component pushes the positioning cover 54 to move slightly. The first elastic element 51 provides longitudinal buffering to avoid stress concentration. After lamination is completed, the lamination cover 42 moves upward, the positioning component 5 automatically resets under the action of the first elastic element 51 and the second elastic element 52, and the transfer mechanism 3 moves the finished component to the finished product conveyor belt 6 for transport.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
