[0002] During the production of photovoltaic (PV) modules, after performance testing and appearance inspection, the modules are conveyed to a sorting machine via an assembly line. During this process, the modules are protected at the corners by a corner protector and then flipped by a flipping machine. After flipping, the junction box cables on the PV modules droop downwards under gravity. These drooping junction box cables are prone to rubbing against the assembly line, and the friction exerted on the junction boxes can cause them to shift or even detach, resulting in defective modules. Utility Model Content

[0003] Therefore, it is necessary to provide a junction box cable anti-scratching device and conveying equipment to solve the problem that drooping junction box cables are prone to scratching with the assembly line.

[0006] The lifting mechanism includes a mounting frame and multiple rotating rollers arranged side by side and rotatably connected to the mounting frame. The telescopic mechanism is connected to the mounting frame. The detection mechanism and the telescopic mechanism are electrically connected to the control mechanism. The detection mechanism is used to detect the presence of junction box cables. When the detection mechanism detects the junction box cables, the control mechanism controls the telescopic mechanism to extend to raise the lifting mechanism so that the lifting mechanism lifts the junction box cables.

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please refer to Figure 1 and Figure 2 As shown, a junction box cable anti-scratching device 100 according to an embodiment of the present invention includes a control mechanism 110, a detection mechanism 120, a telescopic mechanism 130, and a lifting mechanism 140.

[0034] Further integration Figure 3 As shown, the lifting mechanism 140 includes a mounting frame 141 and multiple rotating rollers 142. The multiple rotating rollers 142 are arranged side-by-side and rotatably connected to the mounting frame 141. A telescopic mechanism 130 is connected to the mounting frame 141. When the telescopic mechanism 130 extends, it can raise the lifting mechanism 140. The detection mechanism 120 and the telescopic mechanism 130 are electrically connected to the control mechanism 110. The detection mechanism 120 is used to detect the presence of the junction box cable 21. When the detection mechanism 120 detects the junction box cable 21, the control mechanism 110 controls the telescopic mechanism 130 to extend to raise the lifting mechanism 140, so that the lifting mechanism 140 lifts the junction box cable 21.

[0035] like Figure 4 As shown, after the photovoltaic module 20 on the first conveying device 11 is flipped, the junction box cable 21 hangs downward under the action of gravity. Figure 5 As shown, the junction box cable anti-scratching device 100 can, for example, be installed on a second conveying device 12 that is perpendicular to the conveying direction of the first conveying device 11. Figure 6 As shown, when the downward-hanging junction box cable 21 passes through the detection area of ​​the detection mechanism 120, it is detected by the detection mechanism 120, which then transmits a signal to the control mechanism 110. The control mechanism 110 controls the extension mechanism 130 to extend and raise the lifting mechanism 140, so that the lifting mechanism 140 lifts the junction box cable 21, preventing the junction box cable 21 from rubbing against the first conveying device 11. At the same time, by providing a rotating roller 142 on the lifting mechanism 140, the friction force on the junction box cable 21 can be reduced, preventing the junction box from shifting or falling off.

[0036] The control mechanism 110 can be, but is not limited to, a programmable logic controller (PLC) or an industrial computer. The control mechanism 110 receives the output signal from the detection mechanism 120 and controls the movement of the telescopic mechanism 130 through a control program.

[0037] The detection mechanism 120 may employ, but is not limited to, photoelectric sensors. A photoelectric sensor, for example, is a diffuse reflective photoelectric switch, which includes a emitter and a receiver. After the photovoltaic module 20 is flipped, the junction box cable 21 hangs downwards. When it passes through the detection area of ​​the detection mechanism 120, it reflects the light emitted by the emitter of the detection mechanism 120. The receiver of the detection mechanism 120 receives the reflected light, converts the optical signal into an electrical signal, and transmits it to the control mechanism 110.

[0038] The operating voltage of the detection mechanism 120 is, for example, DC 10~30V. The detection distance of the detection mechanism 120 is, for example, 300mm~600mm.

[0039] Optionally, the telescopic mechanism 130 may include, but is not limited to, at least one of a scissor lift, a push rod, a motor screw drive assembly, and a cylinder.

[0040] like Figure 1 and Figure 3 As shown, the lifting mechanism 140 includes a mounting frame 141 and a plurality of rotating rollers 142 rotatably connected to the mounting frame 141. By having the rotating rollers 142 contact the junction box cable 21, the friction force on the junction box cable 21 can be reduced.

[0041] In some examples, the number of rotating rollers 142 is more than five, for example, five to ten.

[0042] In some examples, the spacing between adjacent rotating rollers 142 is 20mm to 40mm.

[0043] In some examples, the diameter of the rotating roller 142 is 20mm to 30mm.

[0044] In some examples, the length of the rotating roller 142 is 150mm to 200mm.

[0045] The material of the rotating roller 142 can be an organic material such as silicone, or it can be a composite material.

[0046] The mounting bracket 141 can be made of metal materials such as stainless steel or aluminum alloy, or composite materials.

[0047] like Figure 1 and Figure 2As shown, in some examples, the junction box cable anti-scratching device 100 also includes a support mechanism 160. The support mechanism 160 is rotatably connected to the mounting bracket 141 of the lifting mechanism 140. A telescopic mechanism 130 is movably connected to the mounting bracket 141. For example, the support mechanism 160 is rotatably connected to one end of the mounting bracket 141. The telescopic mechanism 130 is movably connected to the middle position of the mounting bracket 141. When the telescopic mechanism 130 extends, it allows multiple rotating rollers 142 to be arranged horizontally. When the telescopic mechanism 130 retracts, the arrangement direction of the multiple rotating rollers 142 is inclined to the horizontal plane.

[0048] like Figure 1 As shown, the support mechanism 160 includes a support plate 161 and a first mounting portion 162 disposed on the support plate 161. The first mounting portion 162 is used to install and fix the entire device. The thickness of the support plate 161 is, for example, 3 mm. The first mounting portion 162 is, for example, a rectangular protrusion. The height of the rectangular protrusion is, for example, 5 mm, the length is, for example, 20 mm, and the width is, for example, 20 mm.

[0049] The support mechanism 160 is preferably made of a material with high rigidity, such as stainless steel, aluminum alloy and other metal materials. Alternatively, composite materials can also be used.

[0050] In some examples, the mounting frame 141 of the lifting mechanism 140 includes a mounting frame body 1412 connecting multiple rotating rollers 142 and a connecting frame 1414 connected to the mounting frame body 1412. The mounting frame body 1412 is, for example, a rectangular frame, more specifically, a rectangular frame with a length of 150 mm, a width of 120 mm, and a thickness of 2 mm. A connecting frame 1414 is connected to each opposite end of the rectangular frame. The connecting frame 1414 is, for example, a rectangular border. The length of the inner hole of the connecting frame 1414 is, for example, 10 mm, and the width is, for example, 5.5 mm. The telescopic mechanism 130 includes a drive component 131 and a connecting crossbar 132. The connecting crossbar 132 movably passes through the connecting frame 1414. The drive component 131 is connected to the connecting crossbar 132. The drive component 131 is capable of raising the connecting crossbar 132, thereby raising the lifting mechanism 140.

[0051] In some examples, the drive component 131 is connected to the connecting crossbar 132 via a support vertical rod 133. One end of the support vertical rod 133 is connected to the drive component 131, for example, via a latch. The other end of the support vertical rod 133 is connected to the middle of the connecting crossbar 132. Thus, as... Figure 2 As shown, the connecting horizontal bar 132 and the supporting vertical bar 133 form a T-shaped structure. The diameter of the connecting horizontal bar 132 is, for example, 5 mm. The diameter of the supporting vertical bar 133 is, for example, 5 mm.

[0052] The materials used to connect the horizontal bar 132 and the supporting vertical bar 133 are, for example, metal materials such as stainless steel and aluminum alloy. Alternatively, composite materials can also be used.

[0053] Optionally, the drive component 131 may include, but is not limited to, at least one of a scissor lift telescopic frame, a push rod, a motor lead screw drive assembly, and a cylinder.

[0054] In the specific example shown, the drive component 131 is a cylinder. The cylinder bore is, for example, 50 mm. The cylinder stroke is, for example, 50 mm.

[0055] like Figure 1 As shown, in some examples, the drive component 131 is connected to a solenoid valve 134. The solenoid valve 134 is, for example, a two-position five-way solenoid valve. The operating voltage of the solenoid valve 134 is, for example, DC 24V. The control mechanism 110 receives the output signal from the detection mechanism 120 and, through a control program, controls the on / off state of the solenoid valve 134, thereby controlling the action of the telescopic mechanism 130.

[0056] In some examples, the support mechanism 160 and the mounting bracket 141 are rotatably connected via a rotating shaft 170. Using a rotating shaft 170 reduces friction between the support mechanism 160 and the lifting mechanism 140, thus reducing wear. The rotating shaft 170 can be made of materials such as metals like stainless steel, plastics like polypropylene or polytetrafluoroethylene, or composite materials. The diameter of the rotating shaft 170 is, for example, 10 mm.

[0057] like Figure 1 and Figure 2 As shown, in some examples, the junction box cable anti-scratching device 100 also includes a connector 180. The connector 180 is connected to the support mechanism 160 and the telescopic mechanism 130 to improve the overall stability of the device.

[0058] In some examples, the connector 180 includes a first connecting member 181. The first connecting member 181 is a horizontally arranged plate-like structure. One end of the first connecting member 181 is connected to the lower end of the support mechanism 160. The first connecting member 181 has a mounting groove in which the telescopic mechanism 130 is mounted. The mounting groove is, for example, a rectangular groove, with a depth of, for example, 3mm to 4mm, a width of, for example, 50mm to 60mm, and a length of, for example, 50mm to 60mm.

[0059] The first connecting component 181 is preferably made of a material with high rigidity, such as stainless steel, aluminum alloy, or other metal materials. Alternatively, composite materials may be used. The first connecting component 181 can be a solid structure or a hollow structure.

[0060] In some examples, the connector 180 includes a second connecting member 182. The second connecting member 182 is connected to the support mechanism 160 via fasteners 1822 and is sleeved on the drive member 131 of the telescopic mechanism 130. More specifically, the support mechanism 160 also includes a second mounting portion 163 disposed on the support plate 161. The second connecting member 182 is connected to the second mounting portion 163 via fasteners 1822. The second mounting portion 163 is, for example, a rectangular protrusion. The height of the rectangular protrusion is, for example, 5 mm, the length is, for example, 20 mm, and the width is, for example, 20 mm.

[0061] The material of the second connecting component 182 is, for example, plastics such as polyvinyl chloride and polycarbonate, or composite materials.

[0062] Furthermore, this utility model also provides a conveying device.

[0063] One embodiment of the conveying equipment includes a conveying device and a junction box cable anti-scratching device 100 as described in any of the above examples. The conveying device is used to convey a photovoltaic module 20 containing the junction box cable 21.

[0064] The aforementioned conveying device may be, but is not limited to, a conveyor belt.

[0065] The aforementioned junction box cable anti-scratching device 100 and conveying equipment are equipped with a detection mechanism 120 for detecting the drooping junction box cables 21 in the photovoltaic modules 20 on the production line. A telescopic mechanism 130 and a lifting mechanism 140 are also included. When the detection mechanism 120 detects the junction box cable 21, the telescopic mechanism 130 extends to raise the lifting mechanism 140, thereby lifting the junction box cable 21 and preventing it from scratching against the production line. Simultaneously, by installing a rotating roller 142 on the lifting mechanism 140, the friction force on the junction box cable 21 is reduced, preventing the junction box from shifting or falling off, thus avoiding component defects and eliminating the need for rework or scrapping of defective components, thereby reducing production costs.

[0066] By using the aforementioned junction box cable anti-scratching device 100, production abnormalities caused by scraping of the junction box cable 21 can be avoided, thus improving production cycle time and efficiency. The junction box cable anti-scratching device 100 is automatically controlled, requiring no manual operation, reducing labor costs, and eliminating safety hazards.

[0067] 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.

[0068] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
