Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic welding tapes, and in particular to a multifunctional photovoltaic cell sheet tinning welding tape conveyor. Background Art

[0002] Photovoltaic welding tape, also known as tinned copper tape or tin-coated copper tape, is an important component of photovoltaic modules. It is used for connection in photovoltaic cell packaging and is applied to the series or parallel connection of photovoltaic cells. It plays an important role in conducting electricity to improve the output voltage and power of photovoltaic modules. Photovoltaic welding tape is an important material in the welding process of photovoltaic modules. Its quality directly affects the current collection efficiency of photovoltaic modules, and has a great impact on the power of photovoltaic modules and the efficiency of photovoltaic power generation systems. It will lead out the electric energy converted from light energy on silicon wafers and transmit it to electrical equipment, playing an important role in conducting electricity to improve the output voltage and power of photovoltaic modules. The quality of photovoltaic welding tape is related to the power transmission efficiency and service life of photovoltaic modules. The performance indicators of photovoltaic welding tape, such as appearance size, mechanical properties, surface structure, resistivity, etc., are important factors affecting the efficiency of photovoltaic power generation, the fragmentation rate of photovoltaic cells, and the long-term reliability and durability of photovoltaic modules. High-quality and high-tech photovoltaic welding tape can not only greatly improve the power generation efficiency, but also reduce the fragmentation rate of photovoltaic cells, and ensure the long-term stable operation of photovoltaic modules. As the production process of photovoltaic welding tape needs to convey the photovoltaic welding tape to the production and processing equipment, there are some defects in the conveying process of photovoltaic welding tape, such as:

[0003] The existing transportation equipment for photovoltaic welding ribbons directly adjusts the tightness of the photovoltaic welding ribbons by pushing the tensioning roller through a motor. During the transportation of the photovoltaic welding ribbons in a relatively tight state, they are prone to excessive contact with the transportation rollers and generate heat, causing the photovoltaic welding ribbons to break in an overly tight state. As the tinned welding ribbons of photovoltaic cells are transported in the conveying device, the tensioning wheels and the contacting transportation device are prone to excessive contact with the surface of the photovoltaic welding ribbons, causing wear, resulting in defects on the surface of the photovoltaic welding ribbons, thereby affecting production quality.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original photovoltaic welding tape conveying device. Summary of the invention

[0056] A limiting clamp 12 is symmetrically and slidably connected to the side walls of the two limiting boxes 5. One side of the limiting clamp 12 is set to a U-shaped opening, and a dust suction roller 13 is rotatably connected in the U-shaped opening of the limiting clamp 12. One side of the limiting clamp 12 is located inside the limiting box 5 and an adjustment component is provided for adjusting the width limiting parts of the dust suction roller 13 located on both sides of the tinned solder strip of the photovoltaic cell to maintain the stability of the transportation of the tinned solder strip of the photovoltaic cell.

The side wall of the cleaning roller 14 is against the positioning scraper 15. The positioning scraper 15 is arranged inside one side of the U-shaped opening of the limiting clamp 12, and the positioning scraper 15 is arranged obliquely, and the bottom end of the positioning scraper 15 is provided with a hollow frame flush with the bottom end of the limiting clamp 12;

[0058] In conjunction with the accompanying drawings Figure 1-10 As shown, the limit box 5 is positioned and installed through the limit frame 1, and the limit clamping plate 12 is located inside the limit box 5 and is slidably connected, as shown in FIG.

[0059] The adjustment components include:

[0060] The metal conductive column 8 is symmetrically installed inside the conveying roller 7, and the inner wall of the groove of the conveying roller 7 is symmetrically provided with metal ports, and a gap is left between the metal port of the conveying roller 7 and the surface of the metal conductive column 8;

[0061] A power-on controller 9 is installed on one side of the metal conductive column 8, and the power-on controller 9 is installed inside the limit box 5;

[0062] An air pump 10, which is connected to the power controller 9 via a cable, and the air pump 10 is installed inside the limit box 5;

[0063] The telescopic bellows 11 has one end connected to the air port of the air pump 10, and the other end of the telescopic bellows 11 is connected to the surface of the limit clamp 12. The telescopic bellows 11 is slidably connected to the hole set inside the limit box 5, and the side wall of the limit box 5 is penetrated by the air pump 10;

[0064] In conjunction with the accompanying drawings Figure 1-10 As shown, the metal conductive pillars 8 are symmetrically arranged inside the conveying roller 7, as shown in FIG. Figure 6-8As shown, a gap is left between the metal strip arranged at the metal port of the conveying roller 7 and the metal conductive column 8 to avoid high temperature caused by contact and rotation, wherein the metal conductive column 8 and the metal port of the conveying roller 7 contain electrons that can move freely, and when the two metals are two centimeters apart, they will conduct electricity, and there are electrons that can move freely in the metal, and the directional movement of the electrons generates current, so that the metal conductive columns 8 located on both sides of the conveying roller 7 are energized, so that the power-on controller 9 connected to this end is electrically connected to the air pump 10, so that the air pump 10 can inflate the inside of the telescopic bellows 11 to push the dust collecting roller 13 on one side of the limit clamp 12 close to both sides of the photovoltaic welding strip, wherein the distance between the metal ports inside the conveying roller 7 is the minimum width distance of the photovoltaic welding strip, and the metal ports inside the conveying roller 7 are elliptical;

[0065] When the width of the photovoltaic welding belt is wide, since the internal opening of the conveying roller 7 is an arc, it does not contact the metal port inside the conveying roller 7. The power-on controller 9 that is powered on on one side remains stable under the control of the synchronous control system and does not start the air pump 10 to work, so as to avoid excessive restriction of the photovoltaic welding belt and cause the surface to be squeezed and worn. When the width of the photovoltaic welding belt is small, it contacts the metal port inside the conveying roller 7, which is convenient for electronic movement to be powered on. When the two power-on controllers 9 are powered on synchronously, they are connected under the control of the synchronous control system, and the air pump 10 is started synchronously to inflate the telescopic bellows 11 and push the limit clamp 12;

[0066] Photovoltaic ribbon detection components include:

[0067] The electromagnet column 19 is mounted on the top of the inner wall of the insulating tube 18, and the surface of the electromagnet column 19 is connected to a conductive winding;

[0068] The thermocouple sensing needle 20 is installed on the surface of a positioning base plate 6, and the thermocouple sensing needle 20 is electrically connected to the conductive winding of the electromagnet column 19. The detection end of the thermocouple sensing needle 20 is installed toward the dust collection roller 13 and the conveying roller 7, and the top of the thermocouple sensing needle 20 is lower than the bottom of the inner groove of the conveying roller 7.

[0069] A light spring column 21 is slidably connected to the bottom end of the insulating cylinder 18, and a spring structure is provided on the outer wall of the light spring column 21, and the spring is connected to the bottom end of the insulating cylinder 18, and a metal sheet is provided on the top end of the light spring column 21 to attract the magnetic field of the electromagnet column 19;

[0070] The surface defect measuring instrument 22 has two ends connected to the bottom end of a light spring column 21 respectively;

[0071] A dynamic roller electronic scale 23 is rotatably connected between two lightweight spring columns 21. The dynamic roller electronic scale 23 is located below the surface defect measuring instrument 22, and a silicone sleeve is provided on the roller surface of the dynamic roller electronic scale 23.

[0072] In conjunction with the accompanying drawings Figure 1-10 As shown, the electromagnet column 19 disposed inside the insulating cylinder 18 is connected to the thermocouple sensing needle 20, as shown in FIG. Figure 5 As shown, the thermocouple sensing needle 20 is close to one side of the conveying roller 7, and is used to detect the heat during the conveying process of the conveying roller 7 and the photovoltaic welding ribbon. The lightweight spring column 21 at the bottom of the insulating cylinder 18 slides downward, so that the roller of the dynamic roller electronic scale 23 directly contacts the photovoltaic welding ribbon, and the photovoltaic welding ribbon is weighed and detected after rolling. The surface defect measuring instrument 22 located above the dynamic roller electronic scale 23 takes pictures of the surface of the photovoltaic welding ribbon to facilitate the inspection of the surface defects of the photovoltaic welding ribbon. After the insulating cylinder 18 and the lightweight spring column 21 cooperate with the spring to descend, and the dynamic roller electronic scale 23 contacts the photovoltaic welding ribbon due to the dynamic roller electric The sub-scale 23 presses the photovoltaic welding tape for conveying. The conveying roller 7 detected by the thermocouple sensing needle 20 is adjusted too tightly, which causes the temperature to rise, causing the thermocouple sensing needle 20 to detect the temperature rise. The voltage difference between the two thermosensitive materials inside the thermocouple sensing needle 20 at the same temperature generates an electric current. The generated current generates a magnetic induction magnetic field inside the solenoid valve, which converts thermal energy into electrical energy, so that the electromagnet column 19 absorbs the metal sheet of the lightweight spring column 21. The spring surrounding the outside of the lightweight spring column 21 cooperates to lift the dynamic roller electronic scale 23, loosening the excessive pressure on the photovoltaic welding tape and adjusting the tension.

[0073] Working principle: When using the multifunctional photovoltaic cell tinning welding belt conveyor, first, one end of the photovoltaic cell tinning welding belt that needs to be rolled up or conveyed is passed through the device to contact and connect with the power pushing equipment, so that the photovoltaic welding belt is located in the device for sliding transportation. As the photovoltaic welding belt is located in the groove on the surface of the conveying roller 7 and contacts the metal port arranged on the surface of the conveying roller 7, the surface of the photovoltaic welding belt is connected to the two sides of the conveying roller 7 to realize power supply. The metal conductive column 8 arranged on one side of the conveying roller 7 is in a power-on state, so that the metal conductive column 8 at the power-on port is connected to the connected power-on controller 9, and the air pump 10 is started to inflate the telescopic bellows 11, and the telescopic push limit splint 12 is rotated to connect the connected dust suction roller 13 to one side of the photovoltaic welding belt. After power is turned on, the dust suction roller 13 on the other side of the photovoltaic welding belt is synchronously started to limit the conveying position of the photovoltaic welding belt. At the same time, the fiber hair on the surface of the dust suction roller 13 cleans the dust on the surface of the photovoltaic welding belt, so that the dust is transported to the cleaning roller 14 and scraped away by the positioning scraper 15. After the photovoltaic welding strip passes through one end of the positioning base plate 6 provided with a thermocouple sensing needle 20, it contacts the dynamic roller electronic scale 23. At this time, the dynamic roller electronic scale 23 is restricted by the lightweight spring column 21 to achieve tension adjustment by pressing down the photovoltaic welding strip. When the tension adjustment is excessive, the thermocouple sensing needle 20 detects that the surface temperature of the dust collection roller 13 and the conveying roller 7 has increased. At this time, the two thermosensitive materials inside the thermocouple sensing needle 20 generate a voltage difference and are connected to the electromagnet column 19, so that the conductive winding and the iron core inside the electromagnet column 19 generate an electromagnetic field, so that the electromagnet column 19 absorbs the metal sheet at the top of the lightweight spring column 21, so that the lightweight spring column 21 drives the dynamic roller electronic scale 23 and the surface defect measuring instrument 22 to lift, and adjust the tightness of the photovoltaic welding strip. At the same time, the surface defect measuring instrument 22 is located between the dynamic roller electronic scale 23 to shoot and scan the surface of the photovoltaic welding strip. At the same time, the dynamic roller electronic scale 23 detects the photovoltaic welding strip for weighing, so as to achieve the weighing of the photovoltaic welding strip and the functional inspection of surface defects.
