Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a device for placing insulating materials for photovoltaic modules. [Background Technology]

[0002] In the manufacturing process of photovoltaic modules, there is a gap in the EVA film at the lead connection location to allow the lead to pass through and be exposed. To fill this gap in the EVA film, a small insulating material is usually used to cover it. This prevents the molten material from being squeezed out of the gap after the film melts during lamination. When placing the insulating material, it needs to pass through the vertical leads on the photovoltaic module. However, the vertical leads on the photovoltaic module can have various orientations and are not always perfectly straight. Therefore, the lead's position needs to be aligned during the placement of the insulating material so that it can smoothly pass through the perforations in the insulating material before being attached to the EVA film surface. Chinese Patent Publication No. CN 115557043A discloses an integrated equipment and process for placing and labeling insulating materials for photovoltaic modules. The equipment includes an insulating material supply unit, a conveying unit for transporting the insulating materials, an insulating material placement robot, and a lead wire alignment unit. The insulating material supply unit first punches and cuts insulating materials to a fixed shape, which then flows onto the conveying unit. The insulating material placement robot picks up the insulating materials from the conveying unit. After the lead wire alignment unit straightens the lead wire, the insulating material placement robot places the picked-up insulating materials onto the lead wire, completing the placement. In this scheme, the placing robot that picks up the insulating materials from the conveying unit and the lead wire alignment unit that straightens the lead wire are located on opposite sides of the lead wire, completing the lead wire straightening and insulating material placement sequentially. The placement robot and lead wire alignment unit are distributed on both sides of the lead wire, which not only occupies a large space but also results in high robot costs, leading to overall equipment complexity and high production costs.

[0003] Therefore, it is necessary to provide a device for placing insulating materials for photovoltaic modules to solve the above-mentioned technical problems. [Utility Model Content]

Detailed Implementation Methods

[0035] Please refer to Figures 1-9 This embodiment is a photovoltaic module insulation material placement device 100. The photovoltaic module insulation material placement device 100 includes a module conveying device 1, an insulation material feeding device 2 located above one side of the module conveying device 1, an insulation material conveying device 3 located at the output end of the insulation material feeding device 2, and a handling and placement device 40 located above the module conveying device 1. The handling and placement device 40 includes a Y-axis drive module 5, a mounting beam 6 driven by the Y-axis drive module 5 to move along the Y direction, and a plurality of handling and placement units 7 movably arranged on the mounting beam 6. The handling and placement unit 7 includes a pick-and-place mechanism 71 for picking up and placing insulation materials, a lead straightening mechanism 72 for straightening the leads on the module, and a visual inspection camera 73.

[0036] The component conveying device 1 includes a feeding conveyor line 11 for conveying components, a lifting module 12 for driving the feeding conveyor line 11 to rise and fall, a short side straightening component 13 for straightening the two opposite short sides of the components, a long side straightening component 14 for straightening the two opposite long sides of the components, and a discharge conveyor line 15 disposed below the feeding conveyor line 11. The feeding conveyor line 11 and the discharge conveyor line 15 are staggered vertically and their conveying directions are perpendicular to each other. After the component is fed into position on the feeding conveyor line 11, the lifting module 12 drives the feeding conveyor line 11 to descend, thereby placing the component on the discharging conveyor line 15. The short side alignment component 13 and the long side alignment component 14 align the component. After the handling and placement device 40 completes the placement of the insulating material 200, the component is output through the discharging conveyor line 15. The input and output directions of the component are rotated by 90°. In this embodiment, the conveying direction of the feeding conveyor line 11 is along the Y direction, and the conveying direction of the discharging conveyor line 15 is along the X direction. The component is fed from the long side on the feeding conveyor line 11 and discharged from the short side on the discharging conveyor line 15, which can realize the reversal of the component and facilitate the subsequent process operation.

[0037] The lifting module 12 includes a lifting motor 121 and a lifting frame 122 driven by the lifting motor 121 to move up and down. Since the lifting module 12 drives the feeding conveyor line 11 to move up and down and needs to transport the components to the discharging conveyor line 15, the feeding conveyor line 11 is disconnected. The feeding conveyor line 11 includes a first feeding conveyor line located outside the discharging conveyor line 15 and a second feeding conveyor line located in the middle of the discharging conveyor line 15. Both the first feeding conveyor line and the second feeding conveyor line are located on the lifting frame 122. When the lifting motor 121 drives the lifting frame 122 to move up and down, the first feeding conveyor line and the second feeding conveyor line move up and down simultaneously.

[0038] The short-side alignment component 13 includes a second cylinder 131, a third cylinder 132 driven by the second cylinder 131 to move in the X direction, and a first alignment wheel 133 driven by the third cylinder 132 to move up and down.

[0039] The long-side alignment component 14 includes a fourth cylinder 141, a fifth cylinder 142 driven by the fourth cylinder 141 to move along the Y direction, and a second alignment wheel 143 driven by the fifth cylinder 142 to move up and down.

[0040] Both the short-side alignment module 13 and the long-side alignment module 14 are mounted on the frame via sliding rails and sliders, enabling them to accommodate photovoltaic modules of different sizes.

[0041] The insulating material feeding device 2 includes an unwinding module 21 arranged in sequence, a punching module 22 that punches lead wire holes in the insulating strip at equal intervals, a feeding module 23 that accurately conveys the strip forward, a cutting module 24 that cuts the insulating strip into insulating materials, a placement platform 25 that carries the cut insulating materials, and a suction and handling module 26 that picks up the insulating materials 200 from the placement platform 25 and transports them to the insulating material conveying device 3.

[0042] The suction and handling module 26 includes a linear drive component 261, a handling frame 262 driven by the linear drive component 261 to move along the X direction, a first cylinder 263 mounted on the handling frame 261, a first adsorption mounting block 264 driven by the first cylinder 263 to move up and down, and several first suction cups 265 mounted at the bottom of the first adsorption mounting block 264. The specific structures of the unwinding module 21, punching module 22, feeding module 23, cutting module 24, and placement platform 25 are described in detail in the "Integrated Equipment and Process for Placing and Labeling Insulating Materials for Photovoltaic Modules" disclosed in Chinese Patent Publication No. CN115557043A, and will not be repeated here.

[0043] The insulating material conveying device 3 includes a lifting motor 31, a first support plate 32 driven by the lifting motor 31 to move up and down, and a conveyor line 33 disposed on the first support plate 32. The conveyor line 33 includes a servo motor 331, a synchronous pulley group 332 driven by the servo motor 331, and a conveyor belt 333 disposed on the synchronous pulley group 332 for conveying insulating materials. The conveyor line 33 conveys insulating materials along the X direction. In this embodiment, since the insulating material feeding device 2 is disposed above the transport and placement unit 7, in order to reduce the movement stroke of the transport and placement unit 7, the lifting motor 31 can drive the conveyor line 33 to move up and down. The lifting motor 31 drives the conveyor line 33 to move upward to receive the insulating materials on the insulating material feeding device 2. Then, the lifting motor 31 drives the conveyor line 33 to move downward to approach the working plane of the transport and placement unit 7. The Y-axis drive module 5 drives the mounting beam 6 to move the transport and placement unit 7 along the Y direction, so that it can move to the conveyor line 33 to pick up the insulating materials 200. This can reduce the movement stroke of the transport and placement unit 7 and improve the efficiency of placing the insulating materials 200.

[0044] In this embodiment, there are three leads on the component that require the placement of insulating materials. Correspondingly, three handling and placement units 7 are provided. The picking and placing mechanisms 71 of the three handling and placement units 7 pick up and place the three insulating materials simultaneously, and the three lead straightening mechanisms 72 simultaneously straighten the leads. In order to improve the versatility of the handling and placement units 7, the three handling and placement units 7 are movably arranged on the mounting beam 6 in the X direction, which can adapt to photovoltaic modules of different sizes. This allows the picking and placing mechanisms 71 to adapt to the insulating materials and leads in different positions, and allows the lead straightening mechanisms 72 to straighten the leads in different positions. Therefore, the handling and placement unit 7 also includes an X-axis drive module 74 mounted on the mounting beam 6, a mounting frame 75 driven by the X-axis drive module 74 to move along the X direction, a pick-and-place mechanism 71, a lead wire straightening mechanism 72, and a vision inspection camera 73, all mounted on the mounting frame 75. The X-axis drive module 74 can drive the mounting frame 75 to move along the X direction, which is suitable for photovoltaic modules of different sizes, can pick up and place insulating materials 200 in different positions, and can also straighten leads in different positions. Two sets of Y-axis drive modules 5 are arranged in parallel, driving the mounting beam 6 to move simultaneously, which can ensure the stability of the movement of the mounting beam 6, so as to ensure the accuracy of the three handling and placement units 7 during operation.

[0045] The pick-and-place mechanism 71 includes a first motor 711 mounted on a mounting frame 75, a lifting block 712 driven by the first motor 711 to move up and down, a ball spline shaft module 713 rotatably mounted on the lifting block 712 and moving up and down simultaneously with the lifting block 712, a second motor 714 driving the ball spline shaft module 713 to rotate, a second suction mounting block 715 located at the lower end of the ball spline shaft module 713, and a plurality of second suction cups 716 located at the bottom of the second suction mounting block 715.

[0046] The ball spline shaft module 713 includes a ball spline shaft, a spline nut, and a ball screw nut. The ball spline shaft is provided with vertical grooves. The ball spline shaft module 713 is prior art and will not be described in detail here.

[0047] In this embodiment, the first motor 711 is positioned above the second motor 714, and both the first motor 711 and the second motor 714 are positioned on the back of the mounting bracket 75. The output shafts of the first motor 711 and the second motor 714 are connected to synchronous pulley sets. The two sets of synchronous pulley sets drive the ball spline shaft module 713 to move up and down or rotate, thereby realizing the picking of insulating materials or the rotation of the insulating materials. Since the placement direction of the insulating materials on the insulating material conveying device 3 is 90° different from the direction of the insulating materials placed on the lead wire, the picking and placing mechanism 71 needs to rotate the insulating materials by 90° when picking up materials from the insulating material conveying device 3. The rotation of the insulating materials is achieved by driving the ball spline shaft module 713 to rotate through the second motor 714.

[0048] The lead wire straightening mechanism 72 includes a second support plate 721 disposed at the bottom of the mounting bracket 75, a slide cylinder 722 disposed on the second support plate 721, a third support plate 723 disposed at the bottom of the slide cylinder 722 and capable of moving up and down by the slide cylinder 722, a front straightening component 724 and a rear straightening component 725 disposed opposite to each other at the front and rear ends of the third support plate 723 for straightening the lead wire.

[0049] A visual inspection camera 73 is mounted on the second support plate 721. It takes photographic inspection pictures of the module's leads before the insulating material is placed to confirm whether there are any abnormalities in the incoming module leads. After the insulating material is placed, it takes photographic inspection pictures of the module's leads and the leads and insulating material after placement to confirm whether the insulating material is placed correctly and to confirm whether there were any abnormalities in the leads during the placement of the insulating material. Below the visual inspection camera 73, a light source plate 76, a reflecting prism 77, and a light-shielding plate 78 are also provided. These components provide sufficient light to the visual inspection camera 73, enabling clearer photographs.

[0050] The third support plate 723 has a clearance opening 7231 in the middle for the second suction cup 716 to move up and down, and a third suction cup 7232 with an adsorption component at the bottom. The third suction cup 7232 adsorbs the component, which can prevent the component from shaking and enable the pick-and-place mechanism 71 to accurately place the insulating material onto the lead wire.

[0051] The front straightening assembly 724 and the rear straightening assembly 725 have the same structure and both include a straightening cylinder 7241, a moving block 7242 driven by the straightening cylinder 7241 to move back and forth, and a straightening plate 7243 installed at the bottom of the moving block 7242 and located in the clearance opening 7231. The straightening plate 7243 is provided with several clearance grooves 7244 that are contoured to avoid the guide wires. The front end of the clearance groove 7244 is provided with a V-shaped guide groove 7245 so that the guide wires with different bending states can smoothly enter the clearance groove 7244. The number of clearance grooves 7244 is set to two, for two guide wires to enter respectively. Two straightening plates 7243 are arranged opposite each other and staggered vertically. For example, the straightening plate 7243 of the front straightening assembly 724 is on top and the straightening plate 7243 of the rear straightening assembly 725 is below it; alternatively, the straightening plate 7243 of the front straightening assembly 724 can be arranged below and the straightening plate 7243 of the rear straightening assembly 725 above it. No limitation is made here. The two straightening plates 7243 extend simultaneously and are inserted between the two leads, allowing the two leads to enter their corresponding clearance grooves 7244 for straightening. Whether the leads are bent inwards or outwards, entering the clearance grooves 7244 ensures straightening. Furthermore, the staggered vertical arrangement of the front and rear straightening assemblies 724 and 725 allows for simultaneous straightening at different heights of the leads, resulting in more precise straightening and improved quality. This, in turn, ensures accurate placement of the insulating material onto the leads.

[0052] When using the photovoltaic module insulation material placement device 100 provided in this solution, after the module is input into position from the feeding conveyor line 11, the lifting module 12 drives the feeding conveyor line 11 to descend, thereby placing the module on the discharging conveyor line 15. The short side alignment component 13 and the long side alignment component 14 align the module, completing the alignment of the module around its perimeter. At the same time, the insulation material feeding device 2 punches and cuts the insulation material strip into multiple insulation material segments 200. The linear drive component 261 drives the transport frame 261 to move to the left above the placement platform 25. The first cylinder 263 drives the first adsorption mounting block 264 to descend, and the first suction cup 265 adsorbs the insulation material segment 200. The first cylinder 263 drives the first adsorption mounting block 264 to rise, and the linear drive component 261... The drive transport frame 261 moves to the right-side insulating material conveying device 3. Simultaneously, the lifting motor 31 drives the first support plate 32 to raise the conveyor line 33 into position. The first cylinder 263 drives the first adsorption mounting block 264 to descend and place the insulating material onto the conveyor belt 333. The lifting motor 31 drives the first support plate 32 to lower the conveyor line 33. At the same time, the Y-axis drive module 5 drives the mounting beam 6 to move along the Y direction, so that the three transport and placement units 7 move onto the conveyor line 33. When the three transport and placement units 7 are in position, the three insulating materials 200 are respectively aligned with the three transport and placement units 7. Each insulating material 2 is located directly below the pick-and-place mechanism 71. The first motor 711 drives the lifting block 712 to drive the ball spline shaft module. 713 descends, causing the second suction cup 716 to descend as well. Simultaneously, the second motor 714 drives the ball spline shaft module 713 to rotate 90°, causing the second suction cup 716 to rotate 90° to pick up the insulating material 200. The first motor 711 drives the lifting block 712 to raise and reset the ball spline shaft module 713. The Y-axis drive module 5 drives the mounting beam 6 to move along the Y direction, moving the three handling and placement units 7 above the three leads respectively. The visual inspection camera 73 takes pictures of the component's leads before placing the insulating material to check for any abnormalities. After confirming that there are no abnormalities, the slide cylinder 722 drives the third support plate 723 to descend to the component surface. The third suction cup 7232 picks up the upper surface of the component, and the front straightening component 7... Simultaneously driven by the straightening cylinders 7241 of the front straightening assembly 724 and the rear straightening assembly 725, the two straightening plates 7243 extend and insert between the two lead wires, allowing the lead wires to enter the clearance groove 7244 and straighten them. The first motor 711 drives the lifting block 712 to lower the ball spline shaft module 713, causing the second suction cup 716 to descend, precisely placing the insulating material 200 onto the upper end of the lead wire. Simultaneously driven by the straightening cylinders 7241 of the front straightening assembly 724 and the rear straightening assembly 725, the two straightening plates 7243 retract simultaneously. The first motor 711 continues to drive the lifting block 712 to lower the ball spline shaft module 713, causing the insulating material 200 to continue descending and be placed on the bottom of the lead wire, completing the straightening of the lead wire and the placement of the insulating material.The slide cylinder 722 drives the third support plate 723 to rise into position. The visual inspection camera 73 takes pictures of the lead wire and insulating material after the insulating material has been placed, confirming that the insulating material has been placed correctly. The short-side alignment component 13 and the long-side alignment component 14 reset and release the components. The components are output via the discharge conveyor line 15, completing the placement of the insulating material for the component. The next component is then conveyed to the material conveyor line 15 via the infeed conveyor line 11 to continue the next round of insulating material placement.

[0053] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
