Description

[0002] Photovoltaic ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is a vital component of solar cell modules. In the production process of photovoltaic modules, ribbon welding is one of the key links. The quality of the ribbon and the welding process directly affect the reliability, conversion efficiency and service life of the photovoltaic modules.

[0003] At present, when photovoltaic welding is performed on photovoltaic modules, the welding tape needs to be laid first. Because photovoltaic modules are assembled from multiple units and the welding tape needs to be welded in series, the corresponding welding tape will be laid on each unit of the photovoltaic module, and then the series welding tape joints will be welded manually or automatically. In this process, after each welding tape on the photovoltaic module is laid, an offset error will inevitably occur, that is, there may be misalignment between the two welding tapes, resulting in direct misalignment welding during the later welding, or external equipment or manual calibration of the welding tape is required before welding, which greatly reduces the welding efficiency of the photovoltaic module, and the photovoltaic welding tape is very inconvenient when radiating, and cannot be laid on the photovoltaic module relatively flatly and neatly, resulting in the quality of the welding will be greatly reduced when the photovoltaic welding tape is automatically welded later. Therefore, a photovoltaic welding tape automatic processing equipment and a processing method thereof are proposed to solve the above-mentioned problems. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1-Figure 7A photovoltaic ribbon automated processing device includes a welding frame 1; a welding gun 2; a ribbon assembly 4 for providing a winding method for flatly laying the photovoltaic ribbon; and a processing assembly 5 for cutting and aligning the laid photovoltaic ribbon. The ribbon assembly 4 includes a reel 401 on which a ribbon strip 402 is wound. The ribbon strip 402 is provided with adhesive, which directly adheres to the photovoltaic module through the adhesive for preliminary positioning, providing stability support for subsequent photovoltaic ribbon welding, and preventing the photovoltaic ribbon from shifting due to the movement of the photovoltaic module. A pressure wheel 404 is connected to the ribbon strip 402, and one end of the ribbon strip 402 is connected to the reel 405. Both the reel 401 and the reel 405 are rotatably connected to the welding frame 1. The pressure wheel 404 contacts the photovoltaic module and then moves the entire welding frame 1 horizontally. The friction and downward pressure are used to control the rotation of the pressure wheel 404. Then, the transmission principle is used to drive the welding ribbon 402, and the welding ribbon 402 is pulled out from the inside of the unwinding reel 401. The overall laying method is similar to the rolling laying method of "correction tape" to achieve the laying of the welding ribbon 4021. When the welding ribbon 4021 passes the position of the pressure wheel 404, due to the influence of the large bend, the welding ribbon 4021 will be separated from the connecting strips 4022 on both sides, thereby achieving rapid laying of the photovoltaic welding ribbon and improving the automatic processing efficiency of the photovoltaic welding ribbon.

[0037] In this embodiment, the welding ribbon strip 402 includes a welding ribbon 4021, with connecting ribbons 4022 connected to both sides of the welding ribbon 4021. Both the welding ribbon 4021 and the connecting ribbon 4022 are provided with a transverse array of perforations 4023. The entire welding ribbon strip 4022 is composed of two parts: the first part is the welding ribbon 4021, and the second part is the connecting ribbon 4022. During radiation, the welding ribbon 4021 is primarily used for laying, while the connecting ribbon 4022 ensures uninterrupted transmission. The multiple perforations 4023 facilitate separation of the welding ribbon 4021 and the connecting ribbon 4022, thereby maintaining the transmission and stretching effect while the welding ribbon 4021 is laid.

[0038] Furthermore, the bottom of the welding frame 1 is connected to a bracket 403 via a spring. A tensioning pulley is rotatably connected to the bracket 403, and the welding strip 402 is overlapped on the tensioning pulley. The bracket 403 slides elastically on the welding frame 1, so the tensioning pulley has an elastic force that can be adjusted up and down, thus providing tension to the welding strip 402.

[0039] Furthermore, the processing assembly 5 includes a cutting device and a calibration device; the cutting device includes a pressing plate 501, the bottom of the pressing plate 501 is connected to a sliding column 502, the sliding column 502 is slidably connected to the welding frame 1, the bottom of the sliding column 502 is connected to a sliding frame 504, the sliding frame 504 is slidably connected to a resistance frame 505, the bottom of the resistance frame 505 is connected to a cutting knife 506, the surface of the sliding column 502 is sleeved with a return spring 503, the return spring 503 is located between the pressing plate 501 and the welding frame 1, and the cutting knife 506 is provided with a limit device for limiting the oblique sliding of the cutting knife 506 to cut the welding strip 402. To cut the welding strip 4021, it is necessary to provide an external force to control the downward movement of the pressing plate 501, and the external force here can be an electric device or manual. Then, the sliding frame 504 is driven downward by the connection of the sliding column 502, and then the sliding contact of the inclined surface is used to drive the resistance frame 505 to move horizontally, and then the cutting knife 506 is driven to slide obliquely, and finally the cutting knife 506 cuts the middle of the laid welding strip 4021, thereby realizing the intermittent laying of the photovoltaic welding strip.

[0040] Furthermore, the limiting device includes a limiting seat 508, to which a positioning frame 507 is fixedly connected. The pressure wheel 404 is rotatably connected to the positioning frame 507. A guide rod 509 is slidably connected within the limiting seat 508. Both ends of the guide rod 509 are fixed to the cutting blade 506. A compression spring 510 is sleeved on the surface of the guide rod 509. One end of the compression spring 510 is connected to the limiting seat 508, and the other end is connected to the spring plate of the guide rod 509. The limiting device allows the cutting blade 506 to be positioned and slid diagonally to prevent misalignment. When the cutting blade 506 moves laterally, the guide rod 509 slides on the limiting seat 508, thereby limiting the sliding direction. After cutting, the elastic force of the compression spring 510 pushes the guide rod 509 to reset.

[0041] In addition, the calibration device includes a pressure frame 512, which is fixed to the bottom of the sliding frame 504. A slope 513 is provided inside the pressure frame 512. The pressure frame 512 is slidably connected to an extrusion rod 514 inside. One end of the extrusion rod 514 is connected to a sliding frame 515, and a clamping strip 517 is connected to the sliding frame 515; one end of the clamping strip 517 is connected to the alignment head 511. When the pressing frame 512 moves down to the limit position, it will synchronously drive the pressing frame 512 to move down, and then use the contact and extrusion of the two inclined surfaces 513 to drive the two extrusion rods 514 to shrink synchronously. Then, the two extrusion rods 514 drive the two card strips 517 to merge through the connection of the slide 515. At this time, the two alignment frames 5111 will drive the two contact heads 5112 to forcibly calibrate and align the joint positions of the two welding strips 4021. Then, external force is used to promote the rotation of the welding gun 2. Using the setting of the lever principle, when the welding gun 2 lowers its head again, it will contact the positions of the two welding strips 4021. After the contact, a contact calibration weld will be directly formed.

[0042] It is worth noting that the carriage 515 is slidably connected to the interior of the winding reel 405 via a connecting rod, and a support spring 516 is provided between the carriage 515 and the winding reel 405. The connecting rod can provide a lateral limit for the extrusion rod 514, limiting the lateral sliding limit of the extrusion rod 514 and the carriage 515. The connection of the support spring 516 can also provide a reset force, providing power for release after calibration.

[0043] Furthermore, the alignment head 511 includes an alignment frame 5111, the bottom of which is connected to a U-shaped contact head 5112. The alignment frame 5111 is connected to the clamping strip 517 via a connecting rod. The U-shaped contact head 5112 can align the two laid welding ribbons 4021, facilitating subsequent welding, thereby avoiding misaligned welding and improving the welding quality of the entire photovoltaic welding ribbon.

[0044] In addition, the welding gun 2 is rotatably connected to the welding frame 1. A tension spring 6 is connected to the bottom right side of the welding gun 2. The left end of the tension spring 6 is connected to the welding frame 1, and the welding frame 1 is connected to the handle 3. The tension spring 6 provides elastic force to stretch and tilt the welding gun 2, preventing contact between the welding gun 2 and the photovoltaic ribbon 4021 during the laying process. Only when an external force is applied will the welding gun 2 rotate and nod, thereby achieving the welding action.

[0045] Example 2

[0046] A photovoltaic ribbon automated processing method comprises the following steps:

[0047] Step S1: Laying and rolling, pressing the welding tape 4021 against the photovoltaic module through the pressing wheel 404, then moving the entire welding frame 1, and using the rolling and rolling of the welding tape strip 402 to horizontally fit the welding tape 4021 on the photovoltaic module; the overall "rolling" contact laying is used to improve the laying efficiency of the welding tape 4021.

[0048] Step S2: Cutting. After one end of the welding ribbon 4021 is laid, the pressing piece 501 is pressed by external force, thereby driving the sliding frame 504 to move downward. Then, the principle of inclined extrusion sliding is utilized to drive the resistance frame 505 and the cutting knife 506 to perform oblique cutting to cut the welding ribbon 4021. Through the cutting process, two methods of intermittent laying and continuous laying of the welding ribbon 4021 can be provided.

[0049] Step S3: repeating steps S1 and S2 to lay and cut the welding ribbon 4021 on another photovoltaic module unit;

[0050] Step S4: Calibration. After pressing the pressure piece 501 to the extreme position by external force again, the pressure frame 512 is moved downward, and then the inclined surface 513 is used to contact and slide, driving the two extrusion rods 514 to shrink, and then through the connection between the slide 515 and the card strip 517, the relative movement of the alignment frame 5111 is driven, and finally the two contact heads 5112 are driven to contact and calibrate with the welding strip 4021; through the set welding strip 4021 calibration, the joint positions of the two welding strips 4021 can be calibrated and aligned to avoid misaligned welding.

[0051] Step S5: Welding: using external force to push the welding gun 2 to rotate around the connection center of the welding frame 1, so that the end welding head of the welding gun 2 contacts and welds with the joint position of the two welding strips.

[0052] Working principle: first, when the photovoltaic welding ribbon needs to be laid in strips on the photovoltaic module, it is necessary to control the pressure wheel 404 on the entire welding frame 1 to contact and abut the photovoltaic module, and then move the entire welding frame 1 horizontally, use friction and downward pressure to control the rotation of the pressure wheel 404, and then use the transmission principle to drive the welding ribbon strip 402 to transmit. The welding ribbon strip 402 will be pulled out from the inside of the unwinding reel 401 and then reeled from the position of the reel 405. The entire welding ribbon strip 402 is composed of two parts, the first part is the welding ribbon 4021, and the second part is the connecting tape 4022. During medium radiation, the main task is to lay the welding tape 4021, while the connecting tape 4022 plays the role of uninterrupted transmission. The overall method is similar to the rolling laying method of using a "correction tape" to achieve the laying of the welding tape 4021. When the welding tape 4021 passes the position of the pressure wheel 404, due to the influence of the large bending, the welding tape 4021 will be separated from the connecting tapes 4022 on both sides. The multiple perforations 4023 are provided to facilitate the separation of the welding tape 4021 and the connecting tape 4022, so that while the welding tape 4021 is laid, the connecting tape 4022 still maintains the transmission stretching effect. When the photovoltaic welding tape is laid, the welding tape 4021 needs to be cut, and an external force needs to be provided to control the downward movement of the pressing piece 501. The external force here can be an electric device or manual. The sliding frame 504 is then driven downward by the connection of the sliding column 502, and the sliding contact of the inclined surface is then used to drive the contact frame 505 to move horizontally, and then the cutting knife 506 is driven to slide obliquely, and finally the cutting knife 506 cuts the middle of the laid welding ribbon 4021. The width of the cutting knife 506 is smaller than the width of the welding ribbon strip 402, so as to avoid cutting the connecting ribbon 4022 at the same time. After that, after releasing the pressing plate 501, the elastic force of the reset spring 503 is used to open it, thereby driving the entire pressing plate 501 to move upward and reset. The welding frame 1 is then moved as a whole to another unit on the photovoltaic module to lay the photovoltaic welding ribbon. This cycle is repeated, and finally the reel-type laying of the photovoltaic welding ribbon is completed.When it is necessary to perform series welding on the laid photovoltaic welding ribbons later, it is necessary to control the extreme downward pressure of the pressing piece 501 again by external force, and it is necessary to control the welding frame 1 to tilt slightly at a certain angle as a whole to prevent the movement of the cutting knife 506 from cutting the welding ribbon 4021 again. When the pressing frame 512 moves down to the extreme position, it will synchronously drive the pressing frame 512 to move down, and then use the contact and extrusion of the two inclined surfaces 513 to drive the two extrusion rods 514 to shrink synchronously. Then, the two extrusion rods 514 drive the two card strips 517 to merge through the connection of the slide 515. At this time, the two alignment frames 5111 will drive the two contact heads 5112 to forcibly align the joint positions of the two welding ribbons 4021. Then, external force is used to push the rotation of the welding gun 2. Using the lever principle, when the welding gun 2 lowers its head again, it will contact the positions of the two welding ribbons 4021. After contact, contact calibration welding will be directly formed, thereby improving the welding quality of the photovoltaic welding ribbon and improving the automated processing welding efficiency of the photovoltaic welding ribbon from the side. The entire welding frame 1 can be mounted on a mobile module or can be handheld, and the specific method of rotation is based on the actual processing.

[0053] To sum up, the entire solution utilizes a transmission laying principle similar to that of a "correction tape". The reel-type laying can effectively improve the laying efficiency and quality of the photovoltaic welding tape. In the later welding process, the photovoltaic welding tape can also be calibrated and aligned, which can also improve the welding quality from the side.

Step S3: repeating steps S1 and S2 to lay and cut the welding ribbon (4021) on another photovoltaic module unit; Step S4: Calibration, after pressing the pressing piece (501) to the limit position again by external force, the pressing frame (512) is moved downward, and then the inclined surface (513) is used to contact and slide, driving the two extrusion rods (514) to shrink, and then the connection between the slide (515) and the card strip (517) drives the relative movement of the alignment frame (5111), and finally drives the two contact heads (5112) to contact and calibrate with the welding strip (4021); Step S5: Welding, using external force to push the welding gun (2) to rotate around the connection center of the welding frame (1), so that the end welding head of the welding gun (2) contacts the joint position of the two welding strips for welding.
