Description

Technical Field

[0001] The utility model relates to a device for treating the surface of the insulation layer of a cable, specifically, a plasma surface treatment device for treating the outer surface of the insulation layer of a photovoltaic irradiated cable. Background Art

[0002] It's well known in the photovoltaic module manufacturing industry that in order to convert solar energy into electricity, photovoltaic modules and the cable boxes used to connect them must be installed outdoors. Because photovoltaic modules and their cable boxes are installed outdoors, the cable boxes must meet high standards for weather resistance, including waterproofing, heat resistance, and UV resistance. Therefore, not only must the cable connectors be located within the junction box, but they must also be glued after connection. As is well known, these cables are made of a conductive core wire and an insulating layer extruded over the conductive core wire. The extruded insulating layer has a relatively smooth outer surface. If used in photovoltaic irradiation cables, this smooth surface can still cause the glue to separate from the insulating layer after years of exposure to wind, sun, and rain. Once this occurs, the weather resistance is significantly reduced. Therefore, traditional cables can only be used in applications where weather resistance, heat resistance, and UV resistance are less critical, and cannot be used in applications where higher weather resistance is required, limiting their scope of application. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a plasma surface treatment device for photovoltaic irradiated cables. Cables treated with this device can be used not only in applications where high weather resistance, such as waterproofing, heat resistance, and UV resistance, is not required, but also in applications where high weather resistance is required, with no limitation on the scope of application.

[0004] The problem to be solved by the utility model is achieved by the following technical solutions:

[0005] The utility model discloses a plasma surface treatment device for photovoltaic irradiation cables, comprising a frame. The characteristic is that there are two sets of plasma emission mechanisms arranged opposite to each other on the frame. The plasma emission mechanisms each contain an ion generator, and there are ion guns on the adjacent sides of the two ion generators, and the two ion guns are respectively connected to the corresponding ion generators. The muzzle ends of the ion guns are arranged opposite to each other, and their centers are located on the same straight line. There is a spacing between the muzzle ends of the two ion guns to facilitate the passage of the photovoltaic irradiation cable to be treated. A pay-out mechanism and a take-up mechanism are respectively provided on both sides of the center of the connection between the two ion guns. The outer end of the photovoltaic irradiation cable on the pay-out mechanism passes through the spacing and is connected to the take-up mechanism.

[0006] Wherein, a first bracket for supporting the muzzle end is provided between the muzzle end of the ion gun and the frame.

[0007] The take-up mechanism is identical to the pay-out mechanism, consisting of a reel seat, a second bracket, a guide wheel, and pay-out and take-up wheels. The second brackets are located below the photovoltaic irradiation cable on either side of the center of the line connecting the two gun muzzles, and the reel seats are fixed to their respective second brackets. The guide wheel and pay-out and take-up wheels have parallel surfaces and are perpendicular to the line connecting the two gun muzzles. They are rotatably mounted on their respective reel seats via axles.

[0008] As can be seen from the above scheme, two sets of plasma emitting mechanisms arranged opposite to each other are provided on the frame 4. The plasma emitting mechanisms both contain ion generators, and there are ion guns on the adjacent sides of the two ion generators. The two ion guns are respectively connected to the corresponding ion generators. The muzzle ends of the ion guns are arranged opposite to each other, and their centers are all located on the same straight line. There is a gap between the muzzle ends of the two ion guns to facilitate the passage of the photovoltaic irradiation cable to be processed. There are a pay-out mechanism and a take-up mechanism on both sides of the center of the connection between the two ion guns. The outer end of the photovoltaic irradiation cable on the pay-out mechanism passes through the gap and is connected to the take-up mechanism. During operation, an air flow is first ejected by the air pump in the ion generator. After the air flow is sent to the ion gun, it is separated by a high-voltage electrode to form a plasma with equal positive and negative charges. The plasma is ejected from the muzzle of the ion gun along the air flow. When the high-energy plasma hits the surface of the cable insulation layer, the energy of the plasma is greater than the binding energy of the molecules on the cable surface, causing the chemical bonds of the molecules on the cable surface to break, and the broken macromolecular chemical bonds form new bonds. However, plasma energy only acts on the cable surface. Consequently, the surface of the cable insulation undergoes physical and chemical changes, becoming roughened. This makes the cable insulation surface more compatible with the glue potting process, thereby improving the cable's water and weather resistance. Therefore, cables treated with this method can be used not only in applications where weather resistance, such as waterproofing, heat resistance, and UV resistance, is less demanding, but also in applications where higher weather resistance is required, with unlimited applicability.

[0012] The present invention will be described in further detail below with reference to the accompanying drawings.

[0013] like Figure 1 、 Figure 2 and Figure 3As shown, the plasma surface treatment device for photovoltaic irradiation cables of the present invention includes a frame 4, on which two sets of plasma emitting mechanisms arranged opposite to each other are provided. The plasma emitting mechanisms each contain an ion generator 5, and an ion gun 6 is provided on the adjacent sides of the two ion generators 5, and the two ion guns 6 are respectively connected to the corresponding ion generators 5. The muzzle ends of the ion guns 6 are arranged opposite to each other, and their centers are located on the same straight line. A gap is left between the muzzle ends of the two ion guns 6 to facilitate the passage of the photovoltaic irradiation cable 3 to be treated. A pay-out mechanism and a take-up mechanism are respectively provided on both sides of the center of the connection between the two ion guns 6; the outer end of the photovoltaic irradiation cable 3 on the pay-out mechanism passes through the gap and is connected to the take-up mechanism.

[0014] The center line of the barrel of the ion gun is located on the horizontal line, and a first bracket 7 for supporting the muzzle end is provided between the muzzle end of the ion gun 6 and the frame 4.

[0015] The take-up mechanism is identical to the pay-out mechanism, both comprising a wheel base, a second bracket, a guide wheel 1, and a pay-out / take-out wheel 2. The second brackets are positioned below the photovoltaic irradiation cable on either side of the center of the line connecting the muzzles of the two ion guns 6, and the wheel bases are fixed to their respective second brackets. The guide wheel 1 and the pay-out / take-out wheel 2 have parallel surfaces and are perpendicular to the line connecting the muzzles of the two ion guns 6. They are rotatably mounted on their respective wheel bases via axles. For simplicity, the wheel base and second brackets are omitted in the accompanying drawings.

[0016] During operation, an air flow is first ejected from the air pump in the ion generator 5. After being sent to the ion gun 6, the air flow is separated by the high-voltage electrode to form a plasma with equal positive and negative charges. The plasma is ejected from the muzzle of the ion gun 6 along the air flow. When the high-energy plasma hits the surface of the insulating layer of the photovoltaic irradiated cable 3, the energy of the plasma is greater than the binding energy of the molecules on the surface of the photovoltaic irradiated cable 3, causing the chemical bonds of the molecules on the surface of the photovoltaic irradiated cable 3 to break, and the broken macromolecular chemical bonds form new bonds. The energy of the plasma can only act on the surface of the photovoltaic irradiated cable 3. In this way, the surface of the insulating layer of the photovoltaic irradiated cable 3 treated with plasma undergoes physical and chemical changes and becomes rough, making it more compatible with the glue. This improves the water resistance and weather resistance of the photovoltaic irradiated cable 3.
