Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a membrane tape opening device. Background Technology

[0002] A photovoltaic (PV) module is a device that converts solar energy into electrical energy. Currently, double-glass PV modules occupy the vast majority of the PV module market. As the name suggests, a double-glass PV module is a PV module whose front and back are both encapsulated by glass. A double-glass PV module typically consists of a back glass layer, a cell string, and a front glass layer, all stacked together.

[0003] To further improve the power generation of double-glass photovoltaic (PV) modules, a reflective film strip is typically attached to the back glass to increase the module's light utilization rate. However, to facilitate current extraction, the back glass of the double-glass PV module also needs to have outlet holes. Currently, to avoid these outlet holes, the reflective film strip must be applied in segments, dividing the strip into multiple sections and using the gaps between adjacent sections to avoid the outlet holes.

[0004] However, segmented film application is inefficient and involves complex automation processes. Furthermore, segmented application results in shorter individual reflective film strips, reducing the contact area between the reflective film strip and the back glass, making it prone to detachment. In addition, segmented application leaves a large area around the cable outlet uncovered by the reflective film strip, reducing the power generation of the photovoltaic module. Utility Model Content

[0005] Therefore, it is necessary to provide a film strip opening device to address the problem of how to improve the power generation of photovoltaic modules while avoiding the outlet holes of the reflective film strip.

[0006] This application provides a membrane tape perforation device for perforating the reflective membrane tape of a photovoltaic module, comprising:

[0007] A perforating tool, used to make holes in the reflective film strip;

[0008] A lifting mechanism is connected to the drilling tool, and the lifting mechanism is used to drive the drilling tool to perform lifting and lowering movements;

[0009] A translation mechanism is provided, which is connected to the lifting mechanism. The translation mechanism is used to drive the lifting mechanism and the drilling tool to perform translational motion together.

[0010] A clamping mechanism is connected to the punching tool and is used to clamp the reflective film strip when the punching tool punches a hole in the reflective film strip.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the drilling tool includes:

[0013] An electric motor, which is mounted on the lifting mechanism;

[0014] A blade connected to the shaft of the motor, the blade being rotated under the drive of the motor to make openings in the reflective film strip.

[0015] In one embodiment, the drilling tool is a laser cutter; or, the drilling tool is a hot melt cutter.

[0016] In one embodiment, the lifting mechanism includes:

[0017] A first guide rail is connected to the translation mechanism;

[0018] The first sliding member is movablely engaged with the first guide rail and is connected to the drilling tool.

[0019] A lifting cylinder is connected to the first sliding member. The lifting cylinder is used to drive the first sliding member to move along the first guide rail, so as to drive the drilling tool to rise and fall.

[0020] In one embodiment, the translation mechanism includes:

[0021] The second guide rail is configured to be arranged along the extension direction parallel to the reflective film strip;

[0022] The second sliding member moves in cooperation with the second guide rail and is connected to the lifting mechanism.

[0023] In one embodiment, the translation mechanism includes a plurality of second sliding members, each of which is movably disposed on the second guide rail, and each of the second sliding members is provided with a lifting mechanism, a hole-opening tool, and a clamping mechanism.

[0024] In one embodiment, the clamping mechanism includes:

[0025] A fixing frame is connected to the drilling tool, and the fixing frame has a through hole;

[0026] A movable rod, which is movably inserted into the through hole;

[0027] A pressure block, connected to the movable rod, is used to press against the reflective film strip;

[0028] An elastic element is sleeved on the movable rod, with one end of the elastic element abutting against the fixed frame and the other end of the elastic element abutting against the pressure block.

[0029] In one embodiment, the fixing frame has two through holes, which are located on both sides of the drilling tool respectively; there are two movable rods, which are inserted into the through holes respectively, and each movable rod is fitted with the elastic element. The pressure block is connected to both movable rods at the same time.

[0030] In one embodiment, the pressure block has a clearance opening located between the two movable rods, and the drilling tool can pass through the clearance opening to drill a hole in the reflective film strip.

[0031] In one embodiment, a limiting block is provided at the end of the movable rod away from the pressure block to prevent the movable rod from dislodging from the through hole.

[0032] The process of perforating the reflective film strip of a photovoltaic module using the aforementioned film strip perforation device is as follows: First, a continuous reflective film strip is attached to the back glass of the photovoltaic module. At this stage, the reflective film strip may cover the lead-out holes on the back glass. Then, the photovoltaic module with the reflective film strip attached is transported to the film strip perforation device. A translation mechanism moves the perforation cutter above the lead-out holes, aligning the cutter with the holes. A lifting mechanism then drives the perforation cutter downwards to contact the reflective film strip. Simultaneously, a pressing mechanism lowers the cutter and the pressing mechanism to press the reflective film strip together. The perforation cutter then begins to perforate the reflective film strip. Throughout this process, the pressing mechanism maintains pressure on the reflective film strip to prevent displacement or misalignment. After perforation, the lifting mechanism raises the perforation cutter and the pressing mechanism to remove them from the reflective film strip. Finally, the perforated photovoltaic module is removed from the film strip perforation device, completing the reflective film application process for the photovoltaic module.

[0033] Compared to the traditional segmented film application method, the film application process using the aforementioned film strip perforation device eliminates the cumbersome segmented application process by first attaching a continuous reflective film strip to the back glass of the photovoltaic module, and then using the film strip perforation device to create perforations at the corresponding outlet positions on the reflective film strip. This facilitates automation. Furthermore, it ensures that the reflective film strip avoids the outlet holes while still covering the area around them, indirectly increasing the power output of the photovoltaic module. It also increases the bonding area between the reflective film strip and the photovoltaic module, thereby improving the adhesion and preventing the reflective film strip from easily detaching.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] like Figure 1 As shown, in the current photovoltaic module 10, in order to avoid the outlet hole 12, the reflective film strip 11 can only be applied in segments, that is, the reflective film strip 11 is divided into multiple segments, and the gap between two adjacent segments of the reflective film strip 11 is used to avoid the outlet hole 12. However, segmented application is inefficient and complex to automate, and segmented application will result in a shorter length of each segment of the reflective film strip 11, reducing the contact area between the reflective film strip 11 and the back glass, thus making the reflective film strip 11 easy to fall off. In addition, segmented application will also result in a large area around the outlet hole 12 not being covered by the reflective film strip 11, reducing the power generation of the photovoltaic module 10.

[0052] like Figure 2 As shown, to solve the problems caused by segmented film application, the inventors of this application have discovered through inventive effort that it is only necessary to first attach a continuous reflective film strip 11 to the photovoltaic module 10, and then make holes at the corresponding outlet holes 12 of the reflective film strip. This avoids the reflective film strip 11 covering the outlet holes 12, while increasing the coverage of the reflective film strip 11, thereby indirectly increasing the power of the photovoltaic module 10. In addition, the automated process is easy to implement, which can effectively improve the product yield. However, because the surface of the photovoltaic module 10 is relatively fragile, the reflective film strip 11 is prone to displacement and misalignment under stress during the drilling process. Therefore, traditional drilling equipment is difficult to use to make holes in the reflective film strip 11 on the photovoltaic module 10.

[0053] Based on this, one embodiment of this application provides a film strip opening device for opening holes in the reflective film strip 11 of a photovoltaic module 10. Specifically, see... Figure 3 as well as Figure 4 One embodiment of the membrane tape perforation device includes a perforation cutter 20, a lifting mechanism 30, a translation mechanism 40, and a pressing mechanism 50.

[0054] The punching tool 20 is used to punch holes in the reflective film strip 11. For example, the punching tool 20 can punch holes in the reflective film strip 11 by means of mechanical punching, laser punching or hot melt punching, etc., without limitation.

[0055] The lifting mechanism 30 is connected to the hole-making cutter 20. The lifting mechanism 30 is used to drive the hole-making cutter 20 to move up and down. For example, the lifting mechanism 30 is used to drive the hole-making cutter 20 to move up and down in a direction perpendicular to the surface of the photovoltaic module 10, so as to move the hole-making cutter 20 closer to or away from the reflective film strip 11.

[0056] The translation mechanism 40 is connected to the lifting mechanism 30, and the translation mechanism 40 is used to drive the lifting mechanism 30 and the hole-opening cutter 20 to perform translational movements together. For example, the translation mechanism 40 is used to drive the hole-opening cutter 20 to move in a direction parallel to the extension direction of the reflective film strip 11, so as to drive the hole-opening cutter 20 to align with the wire outlet hole 12 of the photovoltaic module 10.

[0057] The clamping mechanism 50 is connected to the hole-opening cutter 20. The clamping mechanism 50 is used to clamp the reflective film strip 11 when the hole-opening cutter 20 makes a hole in the reflective film strip 11, so as to limit the displacement and misalignment of the reflective film strip 11 during the hole-opening process.

[0058] Specifically, the process of using the aforementioned film strip opening device to open the reflective film strip 11 of the photovoltaic module 10 is as follows: First, a continuous reflective film strip 11 is attached to the back glass of the photovoltaic module 10. At this time, the reflective film strip 11 may cover the wire exit hole 12 on the back glass. Then, the photovoltaic module 10 with the reflective film strip 11 attached is transported to the area below the film strip opening device. The opening cutter 20 is moved above the wire exit hole 12 by the translation mechanism 40, so that the opening cutter 20 is aligned with the wire exit hole 12. Then, the lifting mechanism 30 drives the opening cutter 20 to descend until it contacts the reflective film strip 11. At the same time, the pressing mechanism 50 descends synchronously with the opening cutter 20 to press the reflective film strip 11. Subsequently, the opening cutter 20 begins to open the reflective film strip 11. During this process, the pressing mechanism 50 keeps the reflective film strip 11 pressed to prevent the reflective film strip 11 from shifting or misaligning during the opening process. After the hole is opened, the lifting mechanism 30 drives the opening cutter 20 and the pressing mechanism 50 to lift so that the opening cutter 20 and the pressing mechanism 50 leave the reflective film belt 11. Finally, the photovoltaic module 10 with the hole opened is sent out of the film belt opening device, thus completing the process of applying reflective film to the photovoltaic module 10.

[0059] Compared to the traditional segmented film application method, the film application process using the aforementioned film strip opening device eliminates the cumbersome segmented film application process by first attaching a continuous reflective film strip 11 to the back glass of the photovoltaic module 10, and then using the film strip opening device to make openings at the positions corresponding to the outlet holes 12 on the reflective film strip 11. This facilitates automation. In addition, it allows the reflective film strip 11 to avoid the outlet holes 12 while ensuring that the reflective film strip 11 covers the area around the outlet holes 12, indirectly improving the power of the photovoltaic module 10. At the same time, it also increases the bonding area between the reflective film strip 11 and the photovoltaic module 10, thereby improving the adhesion between the reflective film strip 11 and the photovoltaic module 10 and preventing the reflective film strip 11 from easily falling off.

[0060] See Figure 4 as well as Figure 5 In some embodiments, the punching tool 20 includes a motor 21 and a blade 22. The motor 21 is mounted on the lifting mechanism 30, and the blade 22 is connected to the rotating shaft of the motor 21. The blade 22 is used to rotate under the drive of the motor 21 to punch holes in the reflective film strip 11. Exemplarily, the blade 22 can be circular, elliptical, or square, etc., and is not limited thereto.

[0061] For example, in other embodiments, the perforating tool 20 is a laser cutter, thereby using a laser to create a hole in the reflective film strip 11. Alternatively, the perforating tool 20 is a hot melt cutter, thereby using high temperature to melt the reflective film strip 11, thus creating a hole in the reflective film strip 11.

[0062] See Figure 5 as well as Figure 6 In some embodiments, the lifting mechanism 30 includes a first guide rail 32, a first sliding member 33, and a lifting cylinder 31.

[0063] The first guide rail 32 is connected to the translation mechanism 40, thereby enabling the first guide rail 32 to perform translational movement under the drive of the translation mechanism 40. For example, the first guide rail 32 extends in a direction perpendicular to the surface of the photovoltaic module 10.

[0064] The first sliding member 33 is movably engaged with the first guide rail 32, and the first sliding member 33 is connected to the drilling tool 20. Specifically, the first sliding member 33 can be slidably connected with the first guide rail 32; or, the first sliding member 33 can be movably engaged with the first guide rail 32 via a roller.

[0065] The lifting cylinder 31 is connected to the first sliding member 33. The lifting cylinder 31 is used to drive the first sliding member 33 to move along the first guide rail 32, thereby driving the drilling tool 20 to rise and fall. Specifically, the first sliding member 33 can be driven to move and rise and fall along the first guide rail 32 by extending and retracting the lifting cylinder 31, thereby driving the drilling tool 20 and the clamping mechanism 50 connected to the drilling tool 20 to rise and fall.

[0066] See Figure 4 as well as Figure 6 In some embodiments, the translation mechanism 40 includes a second guide rail 41 and a second slider 42.

[0067] The second guide rail 41 is configured to extend in a direction parallel to the reflective film strip 11. For example, the second guide rail 41 is mounted above the photovoltaic module 10 and extends in a direction parallel to the reflective film strip 11.

[0068] The second sliding member 42 is movablely engaged with the second guide rail 41, and the second sliding member 42 is connected to the lifting mechanism 30. For example, the second sliding member 42 is connected to a mounting plate 43, and the first guide rail 32 and the lifting cylinder 31 of the lifting mechanism 30 are both mounted on the mounting plate 43. Thus, by driving the second sliding member 42 to move along the second guide rail 41, the lifting mechanism 30, the drilling tool 20, and the pressing mechanism 50 can be moved, allowing the drilling tool 20 to align with the wire outlet hole 12, so that the drilling tool 20 can drill holes in the reflective film strip 11 corresponding to the wire outlet hole 12.

[0069] See Figure 3 In some embodiments, the translation mechanism 40 includes a plurality of second sliding members 42, each of which is movably mounted on the second guide rail 41. Each second sliding member 42 is equipped with a lifting mechanism 30, a hole-opening cutter 20, and a pressing mechanism 50. This allows for simultaneous hole opening at different positions of the corresponding different wire outlet holes 12 of the reflective module, improving the hole-opening efficiency.

[0070] See Figure 4 as well as Figure 5 In one embodiment, for example, the pressing mechanism 50 includes a fixed frame 51, a movable rod 52, a pressing block 54, and an elastic element 53. The fixed frame 51 is connected to the drilling tool 20 and has a through hole (not shown); the movable rod 52 is movably inserted into the through hole; the pressing block 54 is connected to the movable rod 52 and is used to press against the reflective film strip 11. The elastic element 53 is sleeved on the movable rod 52, and one end of the elastic element 53 abuts against the fixed frame 51, while the other end of the elastic element 53 abuts against the pressing block 54.

[0071] Thus, when the punching tool 20 descends to contact the reflective film belt 11 under the drive of the lifting mechanism 30, the pressing mechanism 50 can also descend synchronously until the pressing block 54 abuts against the reflective film belt 11. Under the elastic force of the elastic member 53, it can ensure that the pressing block 54 always presses against the reflective film belt 11 during the punching process, thereby preventing the reflective film belt 11 from being displaced or misaligned.

[0072] See Figure 5In some embodiments, the fixing frame 51 has two through holes, located on both sides of the drilling tool 20. There are two movable rods 52, each corresponding to one of the through holes. Each movable rod 52 is fitted with an elastic element 53. The pressure block 54 is connected to both movable rods 52. This ensures that the pressure block 54 is subjected to balanced forces on both sides, improving its pressing effect on the reflective film strip 11.

[0073] See Figure 4 In some embodiments, the pressure block 54 has a clearance opening 541 located between the two movable rods 52. Specifically, the diameter of the clearance opening 541 is larger than the size of the blade 22, thereby ensuring that the blade 22 can pass through the clearance opening 541 to make a hole in the reflective film strip 11. At the same time, during the hole-making process, the pressure block 54 can press against both sides of the hole position of the reflective film strip 11, further improving the pressing effect on the reflective film strip 11.

[0074] See Figure 5 In some embodiments, a limiting block 55 is provided at the end of the movable rod 52 away from the pressure block 54 to prevent the movable rod 52 from dislodging from the through hole. Specifically, the diameter of the limiting block 55 is larger than the diameter of the through hole, thereby preventing the movable rod 52 from dislodging from the through hole under the elastic force of the elastic member 53, and ensuring the structural stability of the pressing mechanism 50.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
