Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a photovoltaic module hot-heating auxiliary positioning device. Background Technology

[0002] After photovoltaic modules leave the shingling machine, some of the encapsulant film is quite smooth, causing the solar cells to easily slide on the film. This can lead to parallel or series connection before glass bonding, increasing the risk of degradation. Therefore, the manufacturing process of photovoltaic modules typically includes an encapsulant film hot-pressing process. Specifically, after applying positioning tape, a soldering iron is used to hot-press the busbar, encapsulant film, and glass together at high temperature to prevent slippage.

[0003] In related technologies, the common practice is for personnel to manually heat the busbar using a soldering iron. During the heating process, the operator mainly controls the position of the soldering iron tip based on vision and their own heating experience, ensuring that the tip accurately lands on the busbar and does not slip out. However, heating requires a high level of experience from the operator, and prolonged operation necessitates continuous arm exertion, leading to employee fatigue. Furthermore, the soldering iron is difficult to control and has a high breakage rate. Utility Model Content

[0004] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a photovoltaic module hot-heating auxiliary positioning device, which can effectively improve the accuracy of the hot-heating position, reduce the difficulty of operation, and reduce the breakage rate.

[0005] A photovoltaic module soldering auxiliary positioning device is used to position the tip of a soldering iron. The photovoltaic module soldering auxiliary positioning device includes:

[0006] A positioning plate, wherein the positioning plate is provided with hot-pressing holes that penetrate the positioning plate and are used for positioning and engaging with a pen tip inserted therein; and

[0007] A positioning frame is connected to the positioning plate and is arranged circumferentially around the hot-pressing hole.

[0008] In one embodiment, the photovoltaic module hot-heating auxiliary positioning device further includes a positioning member connected to the positioning plate, the positioning member being used to abut against the edge of the photovoltaic module.

[0009] In one embodiment, the positioning element is disposed on the side of the positioning plate opposite to the positioning frame; the positioning element includes a mounting block and a positioning block, the mounting block is connected to the positioning plate, the positioning block is connected to the mounting block and is set at an angle, and the positioning block is used to abut against the edge.

[0010] In one embodiment, the mounting block and the positioning block are arranged perpendicular to each other; and / or, the positioning element is made of high-temperature resistant and heat-insulating material.

[0011] In one embodiment, the photovoltaic module hot-heating auxiliary positioning device further includes a heat insulation pad, which is connected to the positioning plate on the side opposite to the positioning frame, and the heat insulation pad is made of non-metallic material.

[0012] In one embodiment, the heat insulation pad is supported by a high-temperature resistant and heat-insulating material; and / or, the heat insulation pad and the positioning element are an integrated structure.

[0013] In one embodiment, the photovoltaic module hot-heating auxiliary positioning device further includes a handle, which is connected and fixed to the positioning plate.

[0014] In one embodiment, the photovoltaic module hot-heating auxiliary positioning device further includes a heat insulation sleeve, which is disposed on the handle.

[0015] In one embodiment, the hot-dip hole is a square hole or a circular hole; the minimum distance between the two intersection points of the straight line passing through the center of the hot-dip hole and the outline of the hot-dip hole is set as D, 4mm≤D≤6mm.

[0016] In one embodiment, the positioning plate and the positioning frame are made of metal; and / or, the positioning plate and the positioning frame are an integral structure.

[0017] The aforementioned photovoltaic module hot-pressing auxiliary positioning device, in use, places a positioning plate on the busbar, aligning the hot-pressing hole with the position to be hot-pressed on the busbar. Then, the soldering iron tip is inserted into the hot-pressing hole to perform hot-pressing on the busbar. Under high temperature, the busbar, encapsulant film, and glass are stably bonded together at the hot-pressing position. During the hot-pressing process, the positioning frame provides initial positioning for the soldering iron tip, facilitating its insertion into the hot-pressing hole. Furthermore, the tip, fixed within the hot-pressing hole by the positioning plate, ensures that the soldering iron tip moves within the required range of the hot-pressing hole during use, preventing it from slipping out and puncturing or burning the solar cells or encapsulant film. Simultaneously, the positioning frame also prevents the tip from slipping out of the fixture and damaging the encapsulant film or burning the solar cells and encapsulant film. Therefore, the photovoltaic module hot-spotting auxiliary positioning device of this application can easily and accurately control the position of the soldering iron tip, effectively improve the accuracy of the hot-spotting position, reduce the difficulty of operation, and reduce the breakage rate.

[0023] 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.

[0024] As described in the background section, existing soldering operations require a high level of experience from operators, and prolonged operation necessitates continuous arm exertion, leading to employee fatigue. The soldering iron is also difficult to control, and the breakage rate is relatively high. The inventors discovered that this problem arises because both the soldering iron tip and the busbar are made of metal. During contact, the soldering iron can slip off the busbar due to insufficient friction, making it easy for the tip to puncture the battery contacts, causing breakage or burns to the contacts and adhesive film. This affects the soldering effect and increases the workload of repair personnel. Furthermore, relying solely on the human arm to control the soldering iron tip to apply heat to the 4mm wide busbar, and visually confirming that the heat application is precisely on the busbar, easily leads to operator fatigue and the risk of the soldering iron tip slipping and damaging the battery contacts or adhesive film.

[0025] Based on the above reasons, this application provides a photovoltaic module hot-spinning auxiliary positioning device, which can effectively prevent the tip of the soldering iron from slipping out of the busbar and puncturing the battery cell, improve the accuracy of the hot-spinning position, reduce the difficulty of operation, and reduce the breakage rate.

[0026] Please see Figure 1 and Figure 2, Figure 1 This diagram shows a structural diagram of a photovoltaic module 10 according to an embodiment of the present application, in preparation for spot welding of the busbar 15. Figure 2 It shows Figure 1 The diagram shows a cross-sectional view of the photovoltaic module 10 at point AA. The photovoltaic module 10 includes glass 11, encapsulant film 12, solar cells 13, solder ribbons 14, and busbars 15. Both the solar cells 13 and the busbars 15 are connected to the glass 11 via the encapsulant film 12. The solar cells 13 are connected to the busbars 15 via solder ribbons 14. The distance between the busbars 15 and the edge 101 of the photovoltaic module 10 is set to S, where the edge 101 is, for example, as shown... Figure 1 The left edge 101 shown is also the left edge 101 of the glass 11. The spacing S includes, but is not limited to, 11mm to 13mm, specifically 11mm, 12mm, 12.15mm, or 13mm, etc. The width of the busbar 15 is set to W, which includes, but is not limited to, 3mm to 5mm, specifically 3mm, 4mm, or 5mm, etc.

[0027] See Figure 3 and Figure 4 , Figure 3 This application shows a structural diagram of a photovoltaic module hot-heating auxiliary positioning device according to an embodiment of the present application. Figure 4 It shows Figure 3 Enlarged structural view at point B. One embodiment of this application provides a photovoltaic module soldering auxiliary positioning device for positioning the tip of a soldering iron. The photovoltaic module soldering auxiliary positioning device includes a positioning plate 20 and a positioning frame 30. The positioning plate 20 has a soldering hole 21. The soldering hole 21 penetrates the positioning plate 20 and is used for positioning and engaging with the soldering tip inserted inside it. The positioning frame 30 is connected to the positioning plate 20 and is arranged circumferentially around the soldering hole 21.

[0028] The aforementioned photovoltaic module hot-spotting auxiliary positioning device, in use, places the positioning plate 20 on the busbar 15, aligning the hot-spotting hole 21 with the position to be hot-spotted on the busbar 15; then, the tip of the soldering iron is inserted into the hot-spotting hole 21 to hot-spot the busbar 15. Under high temperature, the busbar 15, the encapsulant film 12, and the glass 11 are stably bonded together at the hot-spotting position. During the hot-spotting operation, the positioning frame 30 provides initial positioning for the tip, facilitating its insertion into the hot-spotting hole 21. Furthermore, the tip, fixed by the positioning plate 20 within the hot-spotting hole 21, ensures that the tip moves within the required range of the hot-spotting hole 21 during soldering, preventing it from slipping out and puncturing the solar cell 13 or burning the solar cell 13 and encapsulant film 12. At the same time, the positioning frame 30 also prevents the pen tip from slipping out of the fixture and puncturing the adhesive film 12 or burning the battery contacts 13 and the adhesive film 12. Therefore, it serves as an auxiliary heating element, facilitating accurate control of the soldering iron pen tip position, effectively improving the accuracy of the heating point, reducing the difficulty of operation, and lowering the breakage rate.

[0029] Please refer to Figure 4 Based on the aforementioned embodiments, the photovoltaic module hot-pressing auxiliary positioning device further includes a positioning component 40. The positioning component 40 is connected to the positioning plate 20 and is used to abut against the edge 101 of the photovoltaic module 10. Specifically, the edge 101 can be a side edge of the photovoltaic module 10 that is close to and parallel to the busbar 15. Thus, due to the presence of the positioning component 40, when it abuts against the edge 101 of the photovoltaic module 10, it can quickly position the positioning plate 20 and the positioning frame 30, thereby improving the positional accuracy of the hot-pressing hole 21 and increasing work efficiency.

[0030] To precisely adjust and control the distance between the hot stamping hole 21 and the edge 101, this can be achieved by adjusting and controlling the distance between the hot stamping hole 21 and the positioning member 40. In other words, the distance between the hot stamping hole 21 and the positioning member 40 can be adjusted and controlled according to the distance between the hot stamping position and the edge 101. For example, when the distance between the hot stamping position and the edge 101 is 12mm, the distance between the hot stamping hole 21 and the positioning member 40 is set to 12mm accordingly. Thus, after the positioning member 40 abuts and positions itself against the edge 101, the distance between the hot stamping hole 21 and the edge 101 is 12mm, thereby achieving a distance of 12mm between the hot stamping position and the edge 101.

[0031] For example, the positioning element 40 is disposed on the side of the positioning plate 20 opposite to the positioning frame 30. The positioning element 40 includes a mounting block 41 and a positioning block 42. The mounting block 41 is connected to the positioning plate 20, and the positioning block 42 is connected to the mounting block 41 and disposed at an angle. The positioning block 42 is used to abut against the edge 101. In this way, the mounting block 41 abuts against the adhesive film 12 for positioning, and the positioning block 42 abuts against the edge 101 for positioning, so that the positioning element 40 is stably positioned on the edge 101 of the photovoltaic module 10.

[0032] Specifically, the mounting block 41 and the positioning block 42 are arranged perpendicularly to each other. In other words, the positioning element 40 is arranged in an L-shape. In this way, the mounting block 41 is attached to the adhesive film 12, and the positioning block 42 is attached to the edge 101, which can ensure the stability of the positioning element 40.

[0033] Of course, as some optional solutions, the positioning block 42 can also be set to other shapes, which can be flexibly adjusted and set according to actual needs.

[0034] For example, the positioning element 40 is made of, but is not limited to, high-temperature resistant and heat-insulating materials. Specifically, the positioning element 40 is, but is not limited to, PTFE cloth, rubber materials, rock wool, glass wool, or mineral wool, etc. In this way, the positioning element 40 not only serves a positioning function, but also provides high-temperature resistance and heat insulation, thereby being able to withstand the 330°C temperature of the pen tip during hot stamping operations, while reducing the heat transfer to the adhesive film 12, thus preventing the adhesive film 12 from melting and being damaged due to heat transfer to the adhesive film 12.

[0035] It should be noted that the "positioning block 42" in this embodiment can be a part of the "mounting block 41", that is, the "positioning block 42" and the "other parts of the mounting block 41" are integrally formed; or it can be an independent component that can be separated from the "other parts of the mounting block 41", that is, the "positioning block 42" can be manufactured independently and then combined with the "other parts of the mounting block 41" to form a whole.

[0036] Please see Figure 1 and Figure 4 For example, the photovoltaic module heat-pressing auxiliary positioning device also includes a heat insulation pad 50. The heat insulation pad 50 is connected to the side of the positioning plate 20 opposite to the positioning frame 30. Thus, during the heat-pressing operation, the positioning plate 20 abuts against the adhesive film 12 and busbar 15 through the heat insulation pad 50, and will not directly contact the adhesive film 12, busbar 15 and solar cell 13 below it. This effectively prevents heat from being transferred to the adhesive film 12 during the heat-pressing operation, which could cause the adhesive film 12 to melt or become damaged. It also prevents the solar cell 13 from being damaged when the positioning plate 20 presses against it. Therefore, during the heat-pressing operation, the photovoltaic module heat-pressing auxiliary positioning device can be placed normally on the adhesive film 12 without damaging the solar cell 13.

[0037] It should be noted that, during the hot stamping process, the heat insulation pad 50 comes into contact with the adhesive film 12 and / or the manifold 15. In order to prevent contamination from the heat insulation pad 50 coming into contact with the adhesive film 12 and the manifold 15, the side of the heat insulation pad 50 away from the positioning plate 20 must be kept clean.

[0038] For example, the heat insulation pad 50 is made of high-temperature resistant and heat-insulating materials. Thus, the heat insulation pad 50 can withstand high temperatures while providing good heat insulation, preventing the adhesive film 12 from melting and being damaged. The materials of the heat insulation pad 50 and the positioning element 40 can be the same or different, and can be flexibly adjusted and set according to actual needs.

[0039] Optionally, the heat insulation pad 50 and the positioning element 40 can be an integral structure, for example, by injection molding. In this way, the heat insulation pad 50 and the positioning element 40 can be securely installed on the positioning plate 20, and are less likely to fall off during use.

[0040] For example, the heat insulation pad 50 and the positioning element 40 can each be formed on the positioning plate 20 by injection molding, or they can be fastened to the positioning plate 20 by snap-fit, adhesive or fasteners. There are no limitations here, and they can be flexibly adjusted and set according to actual needs.

[0041] Please see Figure 3 and Figure 4 For example, the photovoltaic module hot-spotting auxiliary positioning device also includes a handle 60. The handle 60 is connected and fixed to the positioning plate 20. Thus, during hot-spotting operations, by holding the handle 60, the positioning member 40 is brought into contact with the edge 101, thereby ensuring that the position of the hot-spotting hole 21 does not shift during the hot-spotting operation and improving the ease of operation. In addition, the handle 60 is located away from the tip of the soldering iron, effectively preventing burns.

[0042] For example, the photovoltaic module hot-scalding auxiliary positioning device also includes a heat insulation sleeve 61. The heat insulation sleeve 61 is disposed on the handle 60. In this way, the heat insulation sleeve 61 has a heat insulation function, which can prevent the handle 60 from getting too hot when held.

[0043] For example, the outer wall of the heat insulation sleeve 61 may be, but is not limited to, curved, specifically, a circular arc or an elliptical arc. Thus, the heat insulation sleeve 61 provides better comfort and better fatigue prevention.

[0044] For example, the handle 60, the positioning plate 20 and the positioning frame 30 may be an integral structure, including but not limited to, formed by forging, stamping, die casting or laser milling, or they may be connected and fixed by welding.

[0045] In this embodiment, the handle 60, positioning plate 20, and positioning frame 30 are all made of metal materials, which ensures the structural strength of the product, allows it to withstand high temperatures, and makes it less prone to damage. The metal materials include, but are not limited to, stainless steel, iron, copper, or aluminum.

[0046] Generally speaking, the outer diameter of the tip of the soldering iron in related technologies is, for example, 3mm to 4mm, specifically 3mm, 3.5mm or 4mm, etc.

[0047] For example, the hot-point hole 21 is a square or round hole; the minimum distance between the two intersection points of the straight line passing through the center of the hot-point hole 21 and the outline of the hot-point hole 21 is set as D, 4mm≤D≤6mm. Optionally, D includes, but is not limited to, 4mm, 4.5mm, 5mm, 5.5mm or 6mm. In this way, the distance D is greater than the outer diameter of the pen tip, so that the pen tip can normally pass through the hot-point hole 21 and make contact with the manifold 15, and the tilt angle can be adjusted according to actual needs, so as to smoothly carry out the hot-point operation.

[0048] During each soldering operation, the soldering iron tip, aided by the photovoltaic module soldering auxiliary positioning device, only solders within the soldering hole 21. By defining the soldering area, employees can more easily visually determine the soldering position, reducing employee fatigue. Simultaneously, it effectively prevents damage to the solar cells 13 and encapsulant film 12 caused by the soldering iron sliding against the busbar 15, thus reducing the production of downgraded modules.

[0049] In one embodiment, the hot-point hole 21 is a square hole with a side length of 5mm. The outer diameter of the soldering iron tip is 3.5mm, and the width W of the busbar 15 is 4mm. The side length of the hot-point hole 21 is 1.5mm larger than the outer diameter of the soldering iron tip, which serves to position the soldering iron tip and prevent it from slipping out of the hot-point hole 21.

[0050] In some embodiments, the positioning frame 30 is, but is not limited to, a square frame, specifically a rectangular frame. The outline shape of the positioning frame 30 is consistent with the outline shape of the positioning plate 20. Optionally, the side length of the positioning frame 30 is, for example, 18mm to 22mm, specifically, 18mm, 20mm, or 22mm, etc.
