Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing technology, and more specifically to a four-sided framing device for photovoltaic modules. Background Technology

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy. They are mainly composed of eight materials: solar cells, EVA, tempered glass, backsheet, solder strips, silicone, junction box, and frame. These components are sealed into a whole through series and parallel connections to prevent corrosion of the cell electrodes and interconnects. The encapsulation also prevents the cells from breaking and facilitates outdoor installation. The encapsulation materials and quality of photovoltaic modules directly affect their lifespan and reliability. Most common photovoltaic modules have a flat-plate encapsulation structure.

[0003] During the framing process, the laminate is framed around its perimeter to improve mechanical strength. To ensure frame stability, adhesive is applied inside the frame before installation. After adhesive application, the four glued frame edges are sequentially placed into the designated framing positions using grippers. Because the frame installation requires ensuring the angles align with the frame and the edges of the laminate, the equipment installation process demands high precision. Traditional equipment is prone to frame misalignment or incorrect angles during installation, leading to frame misalignment, failure to framing, and ultimately, frame deformation and damage to the laminate.

[0004] Secondly, the stress during installation can cause the laminated components to wobble and shift, increasing the error. After framing, the assembled photovoltaic modules still need to be manually removed and placed on a conveyor line to flow into the next section for installing junction boxes. The operation is not simplified enough, and workers are required to transfer the products between sections. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a four-sided framing device for photovoltaic modules. By fixing and calibrating the positions of the frame and laminates before assembly, it prevents misalignment, ensures accurate installation, and significantly reduces the probability of installation failure.

Detailed Implementation

[0036] like Figure 1 , 4As shown in Figures 9 and 10, a photovoltaic module four-sided framing device mainly comprises a lifting conveyor belt 1, a laminate 11 calibration mechanism 6, a frame calibration mechanism 5, a short frame clamping mechanism 3, and a long frame clamping mechanism 2, each with its own function. The lifting conveyor belt 1 mainly changes the height of the laminate 11 for easy transfer. The long frame clamping mechanism 2 and the short frame clamping mechanism 3 are used to clamp and fix the frame 10; the laminate 11 calibration mechanism 6 and the frame calibration mechanism 5 calibrate the positions of the frame 10 and the laminate 11 respectively before installation; the laminate 11 is rectangular, so the frame 10 has both short and long frames.

[0037] like Figure 1 , 2 As shown in Figures 3, 4, and 11, the laminate 11 moves along the lifting conveyor belt 1, with one side of the long side of the laminate 11 perpendicular to the conveying direction of the lifting conveyor belt 1. Short frame clamping mechanisms 3 are provided on both sides of the short side of the lifting conveyor belt 1. The lifting conveyor belt 1 stops moving after the laminate 11 moves to the designated position. Long frame clamping mechanisms 2 are provided on both sides of the long side of the laminate 11. The long frame clamping mechanism 2 and the short frame clamping mechanism 3 respectively clamp their corresponding frame 10 in the first frame placement groove 215 and the second frame placement groove 311, and push the frame 10 toward the edge of the laminate 11.

[0038] like Figure 1 , 3 As shown in Figures 4, 9, and 10, the lifting conveyor belt 1 is configured as follows:

[0039] The lifting conveyor belt 1 includes: a conveyor belt body 111, telescopic support legs 112, and a telescopic cylinder 113; the bottom of the conveyor belt body 111 is provided with telescopic support legs 112; telescopic cylinders 113 are fixed at the lower center of both ends of the conveyor belt body 111; the telescopic ends of the telescopic cylinders 113 are fixed to the bottom plate 114 of the conveyor belt body 111, driving the conveyor belt body 111 to move up and down; after the conveyor belt body 111 is raised to its highest position, it is flush with the surface of the conveyor belt inside the frame conveyor assembly 4, and the height of the conveyor belt body 111 after being raised to its highest position is higher than the plane where the long frame clamping mechanism 2 and the short frame clamping mechanism 3 are located. This ensures that after being raised, the framed laminate 11 is detached from the framing equipment, preventing other framing equipment from causing obstruction.

[0040] like Figure 2 , 3 As shown in Figures 4, 5, 9, and 10, the long frame clamping mechanism 2 is configured as follows:

[0041] One or more sets of long frame clamping mechanisms 2 are located on both sides of the long side of the laminate 11. The main function of this mechanism is to fix and clamp two long frames. The long frame clamping mechanism 2 includes: a first stroke frame 211, a long frame drive motor 212, a first frame mounting screw 213, a sliding frame 214, a first frame placement groove 215, a long frame first clamping cylinder 216, a long frame second clamping cylinder 217, a first pull-back plate 219, and a first pressure block 220; the first stroke frame 211 is arranged below the laminate 11 along the conveying direction; rails 222 are fixed on both sides of the first stroke frame 211; a sliding frame 214 is fixed at the bottom of the first frame placement groove 215, and the sliding frame 214 is sleeved on the crossbeam of the first stroke frame 211; the sliding frame 214 has a groove corresponding to the position of the rail 222; the sliding frame 214 moves along the rail 222; the first frame mounting screw 213 is symmetrically inserted below the stroke frame; the sliding frame The bottom of 214 is correspondingly mounted on the first frame mounting screw 213; the first frame mounting screw 213 is connected to the drive end of the long frame drive motor 212; the two ends of the back of the first frame placement groove 215 are respectively vertically fixed with the long frame first clamp cylinder 216; the telescopic end of the long frame first clamp cylinder 216 is fixed with the first mounting plate 218, and the long frame second clamp cylinder 217 is horizontally fixed on the first mounting plate 218; the telescopic end of one end of the long frame second clamp cylinder 217 is fixed with the first pull-back plate 219; the bottom of the first pull-back plate 219 has a protruding edge 221 that fits into the frame 10, and the first pull-back plate 219 clamps the frame 10 in the horizontal direction; the telescopic end of the other end of the long frame second clamp cylinder 217 is fixed with the first pressure block 220. The long frame first clamping cylinder 216, located in the middle section of the long frame clamping mechanism 2, is positioned in the middle of the first frame placement groove 215. The first pressing block 220 is connected to the telescopic end of the long frame first clamping cylinder 216. After the first pressing block 220 presses down, it presses the frame 10 vertically. The telescopic movement of the long frame first clamping cylinder 216 controls the lifting and lowering, while the telescopic movement of the long frame second clamping cylinder 217 is responsible for horizontal movement. When used together, they can change the position of the first pull-back plate 219 and engage with the inner side of the frame 10.

[0042] like Figure 2 , 3 As shown in Figures 4, 6, 7, and 8, the short frame clamping mechanism 3 is configured as follows:

[0043] One or more short frame clamping mechanisms 3 are provided, located on both sides of the short side of the laminate 11; the main function of this mechanism is to fix and clamp the two short frames. The short frame clamping mechanism 3 includes: a second stroke frame 322, a second frame placement groove 311, a short frame first clamping cylinder 312, a short frame second clamping cylinder 313, a second pull-back plate 314, a second pressure block 315, a short frame drive motor 316, a movable plate 317, a first slider 318, and a second frame mounting screw 319; the movable plate 317 is slidably provided on the surface of the second stroke frame 322 along the direction of the laminate 11; the second stroke frame 322 is provided with a movable groove 320, and the second frame mounting screw 319 is rotatably provided in the movable groove 320; the first slider 318 is fixed at the bottom of the movable plate; the first slider 318 passes through the second frame mounting screw 319 and moves along the movable groove 320; the second frame placement groove 311 is fixed on the side of the movable plate 317 near the laminate 11; the back of the second frame placement groove 311 One or more short frame first clamping cylinders 312 are vertically fixed; a second mounting plate 321 is fixed to the telescopic end of the short frame first clamping cylinder 312; a short frame second clamping cylinder 313 is horizontally fixed to the surface of the second mounting plate 321; a second pull-back plate 314 is fixed to the telescopic end of the short frame second clamping cylinder 313; the second pull-back plate 314 has the same structure as the first pull-back plate 219; a second pressure block 315 is fixed to the telescopic end of the short frame first clamping cylinder 312 located in the middle of the movable plate 317; the second pressure block 315 has the same structure as the first pressure block 220; the first frame placement groove 215 and the second frame placement groove 311 form an L-shaped bending mechanism, and the frame 10 is placed at the included angle of the bend; the first frame placement groove 215 and the second frame placement groove 311 are multi-segmented to ensure the stability of the frame 10 after clamping.

[0044] like Figure 1 , 11 As shown in Figures 12 and 13, the border conveying component 4 is configured as follows:

[0045] The frame conveying assembly 4 transfers the glued frame 10 from the previous process stage to this stage. The glued frame 10 is gripped by a mechanical gripper and placed in the long frame clamping mechanism 2 and the short frame clamping mechanism 3 respectively before framing. The frame conveying assembly 4 includes a conveyor frame 411, a conveyor rail 412, a conveyor screw 413, a conveyor motor 414, a second slider 415, a conveyor seat 416, a lifting plate 417, and a slot 418. The conveyor rail 412 is mounted on the conveyor frame 411, and the conveyor seat 416 slides on the conveyor belt. The second slider 415 is fixed to the bottom of the conveyor seat 416. The conveyor screw 413 is movably mounted on the conveyor frame 411. The second slider 415 passes through the screw and is driven by the conveyor motor 414. The lifting plate 417 is movably mounted on the conveyor seat 416. The slot 418 for placing the frame 10 is fixed on the lifting plate 417. Furthermore, the frame conveying assembly 4 also features a lifting function. This is to facilitate the use of a sliding rod 419 fixed to the bottom of the lifting plate 417 of the mechanical gripper. A sliding sleeve 420 is provided on the conveying seat 416 corresponding to the position of the sliding rod 419. The sliding rod 419 moves up and down along the sliding sleeve 420. A lifting cylinder 421 is fixed to the bottom of the conveying seat 416. The telescopic end of the lifting cylinder 421 passes through the conveying seat 416 and is fixed to the bottom of the lifting plate 417, driving the lifting plate 417 to move up and down. The mechanical gripper can be operated by an industrial robot; however, this part uses existing equipment and will not be described in detail.

[0046] like Figure 2 , 3 As shown in Figures 4, 6, and 7, the border calibration mechanism 5 is configured as follows:

[0047] The frame calibration mechanism 5 is designed to prevent offset issues before the frame 10 is gripped. Specifically, this offset issue refers to the fact that, because the frame 10 is placed within the slot 418, it can shift along both sides of the slot 418. After the gripper grips it, this offset persists, causing the first frame placement slot 215 and the second frame placement slot 311 to shift along the slot direction after placement. Therefore, calibration is required. The frame calibration mechanism 5 includes a long-side calibration cylinder 511 and a short-side calibration cylinder 512; both the long-side calibration cylinder 511 and the short-side calibration cylinder 512 are equipped with a first push plate 513; the frame calibration mechanism 5 is positioned at the four corners of the frame 10. Every two long-side calibration cylinders 511 push one long frame, and every two short-side calibration cylinders 512 push one short frame. Therefore, adjacent long-side calibration cylinders 511 and short-side calibration cylinders 512 are arranged vertically. Each first push plate 513 corresponds to half of the cross-section of the frame 10 to prevent obstruction during retraction.

[0048] like Figure 2 , 3 As shown in Figures 4, 6, and 7, the laminate calibration mechanism 6 is configured as follows:

[0049] The laminate calibration mechanism 6 calibrates the position of the laminate 11. The laminate calibration mechanism 6 includes a first plate calibration cylinder 611 and a second plate calibration cylinder 612; a partition gap is provided in the middle of the first frame placement groove 215; the first calibration cylinder is fixed within the partition gap of the frame placement groove; the second calibration cylinder is fixed to the surface of the movable plate 317; a second push plate 613 is fixed to the telescopic ends of the first plate calibration cylinder 611 and the second plate calibration cylinder 612. The first plate calibration cylinder 611 and the second plate calibration cylinder 612 are respectively responsible for the edge of their respective laminate 11. Simultaneous pushing calibrates the position of the laminate 11. Therefore, the positions of the first plate calibration cylinder 611 and the second plate calibration cylinder 612 need to be set in advance, with the distance precisely aligned according to the specifications of the laminate 11.

[0050] like Figure 1 , 3 As shown in Figures 4 and 5, other auxiliary components are set as follows:

[0051] In addition to the aforementioned mechanisms, there are several auxiliary components. A reversing conveyor belt 7 is installed at the discharge end of the lifting conveyor belt 1; the reversing conveyor belt 7 is used to change the direction of the conveying path. An adsorption plate 8 is fixed at the location of the mounting frame 10 on the lifting conveyor belt 1. The adsorption plate 8 is a non-standard component, with suction cups on its surface. The suction cups are connected to an air compressor to provide suction. After the lifting conveyor belt 1 descends, the adsorption plate 8 adsorbs and fixes the laminate 11. One or more auxiliary rollers 9 are movably arranged on both sides of the lifting conveyor belt 1. Unless otherwise described, the fixing methods are all achieved using welding or threaded fastening techniques commonly used by industry professionals.

[0052] The workflow is as follows:

[0053] The frame 10 is conveyed from the previous process section to the discharge end of the frame conveying assembly 4; the laminate is conveyed by other conveyor belts to the feed end of the lifting conveyor belt 1 and stops moving and descends after reaching the designated position. After descending, the adsorption plate 8 adsorbs the laminate 11; the laminate 11 calibration mechanism 6 is activated to first calibrate the position of the laminate, and then resets after the calibration is completed to prevent the laminate calibration mechanism from obstructing the clamping frame. The mechanical gripper grabs the frame 10 and places it on the long frame clamping mechanism 2 and the short frame clamping mechanism 3 respectively, specifically in the first frame placement slot 215 and the second frame placement slot 311 on the mechanism. The frame calibration mechanism 5 starts to operate to calibrate the position of the four frames 10. After the frame calibration mechanism 5 completes the calibration, the long frame clamping mechanism 2 and the short frame clamping mechanism 3 clamp and fix it. After fixing, it begins to move towards the edge of the laminate 11 to start the frame loading. After framing is completed, the long frame clamping mechanism 2 and the short frame clamping mechanism 3 release their respective first pull-back plate 219, second pull-back plate 314, first pressure block 220, and second pressure block 315. The framed laminate 11 is then lifted by the lifting conveyor belt 1 and continues to run, flowing out of the equipment and into the reversing conveyor belt 7. The equipment is then reset to prepare for the framing of the next laminate 11.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
