Description

Technical Field

[0001] This application relates to the field of photovoltaic modules, and more particularly to a ribbon welding system. Background Technology

[0002] Currently, in the photovoltaic industry, the production of welding strips involves using pressure rollers to perform multiple stretching operations on copper strips to achieve specified dimensions. In the initial stage, the copper strip is continuously stretched by multiple pressure rollers, gradually forming a flat strip with an approximately rectangular shape, achieving preliminary adjustment of the strip's width and thickness. In the intermediate stage, the flat strip is further stretched using the combined action of multiple pressure rollers and specific molds to ensure it reaches a standard rectangular shape. Finally, pressure rollers with roller patterns are used to stretch the rectangular flat strip into the specified shape.

[0003] The embossed pressure roller consists of a patterned upper pressure roller and a smooth lower pressure roller. When the flat strip passes through it, both sides become a structure with one smooth and one rough side, meeting the product's shape requirements. Although the final pressure roller has a good embossing effect, the transfer rate of its two rollers is low, which cannot meet the high-efficiency production of the production line, resulting in low capacity. Furthermore, when its rollers are damaged, replacement is difficult, time-consuming, and labor-intensive. If the patterned upper pressure roller is damaged, a new mold must be made, resulting in high maintenance and replacement costs.

DETAILED DESCRIPTION

[0033] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0034] As described in the background, in the initial stage, the copper strip is continuously elongated by multiple compression rollers to gradually form a flat strip in a nearly rectangular shape, achieving preliminary adjustment of the width and thickness of the copper strip; in the intermediate stage, the flat strip is further elongated by the coordinated action of multiple compression rollers and a special mold to ensure that the flat strip reaches the standard rectangular shape; in the final stage, the rectangular flat strip is elongated into a specified shape by a compression roller with a strip roller pattern. The compression roller with a strip roller pattern is composed of an upper compression roller with a pattern and a smooth lower compression roller. When the flat strip passes through it, the two sides become one smooth and one rough structure, meeting the product shape condition index. Although the last compression roller has good embossing effect, the transfer rate of its two rollers is low, which cannot meet the efficient production of the production line, and the production capacity is low. When the roller is damaged, it is difficult to replace, time-consuming and laborious. If the upper compression roller with a pattern is damaged, a new mold needs to be made, and the maintenance and replacement cost is high.

[0035] To solve one or more of the above problems, the core of the present application is to provide a solder strip processing system which uses a wire drawing structure instead of a final embossing compression roller mechanism to reduce production cost and improve production efficiency of the system.

[0036] REFERENCE Figure 1 For example, a solder strip processing system includes a pay-off mechanism 10 for driving the solder strip 70 to move along the running direction of the production line; at least one compression roller mechanism 20 is provided in the running direction of the production line for preliminary elongation of the solder strip 70 paid off from the pay-off mechanism 10; at least one wire drawing structure is provided downstream of the compression roller mechanism 20, for example, Figure 1The three drawing structures are respectively a first drawing structure 30, a second drawing structure 40 and a third drawing structure 50. The first drawing structure 30 has a round shaped structure, the second drawing structure 40 has an elliptical shaped structure, and the third drawing structure 50 has a sawtooth shaped structure. The three drawing structures are used to draw the shape of the welding strip 70 passing through the drawing structures into the corresponding shaped structure. The traction wheel 60 can be arranged between different drawing structures according to the production line to apply a traction force to the drawn welding strip 70.

[0037] Embodiment 1

[0038] Embodiment 1 of the present application provides a welding strip processing system, referring to Figures 2 to 5 , comprising at least one drawing structure 100 arranged in the moving direction of the welding strip. The drawing structure 100 is internally provided with a drawing channel 110. The drawing channel 110 is provided with a shaped structure 120. The shaped structure 120 has a preset shape towards at least one side of the welding strip, so that at least one side of the welding strip passing through the drawing channel 110 forms a shape corresponding to the preset shape.

[0039] In the running process of the welding strip processing production line, a plurality of drawing structures 100 are arranged. The cross sections of the shaped structures 120 of different drawing structures 100 have different shapes. The welding strip passing through the drawing structures will be drawn into different structures. In the usual drawing process, the cross section of the shaped structure 120 of the last drawing structure 100 in the production line direction is set according to the requirements of the preset product structure shape. The welding strip is drawn into the final drawing structure 100 to make its structure meet the requirements of the product. Compared with the original embossing drawing process of the welding strip by the patterned roller at the end of the drawing process, the design of the present application can accurately draw the welding strip passing through the drawing channel 110 to meet the requirements of different product structure shapes. Compared with the patterned roller, the operation of the present application is more simple. The welding strip can directly pass through the drawing channel 110 at high speed without slow roller pressing operation. Not only the production rate is improved, but also the whole drawing process is more efficient due to the compact layout of different drawing structures 100. In addition, since the production cost of the drawing structure 100 is low and easy to replace and maintain, when the product design requirements change, only the drawing structure 100 with a new cross section shape needs to be re-modeled to quickly adapt to the changes in production requirements, avoiding the high cost problem of re-modeling the roller. Thus, an efficient, economical and flexible solution is provided for the welding strip production and processing in the photovoltaic industry. It should be noted that the above cross sections refer to the cross sections in the moving direction of the welding strip.

[0040] Preferably, referring to Figures 3 to 5The wire drawing structure includes opposite first end 101 and second end 102; the first end 101 is inwardly recessed to form a recessed structure 103; the bottom of the recessed structure 103 is at least partially and the second end 102 is through-communicated to form a wire drawing channel 110.

[0041] The recessed structure 103 serves as a guide structure, which not only improves the guiding efficiency of the wire drawing channel 110, but also further optimizes the wire drawing forming process of the welding strip by at least partially and the second end 102 being through-communicated. Specifically, the recessed structure 103 can effectively guide the welding strip into the wire drawing channel 110, reduce the deviation and wrinkle of the welding strip, and ensure the stability and consistency of the welding strip in the wire drawing process. In addition, the wire drawing channel 110 formed by the communication of the recessed structure 103 and the second end 102 helps the welding strip to smoothly transition in the wire drawing channel 110, and at the same time utilizes the shaping structure 120 therein to draw the welding strip, reducing the damage to the welding strip material caused by friction, thereby improving the surface quality and overall strength of the welding strip after wire drawing.

[0042] Preferably, the preset shape of the cross section of the shaping structure at least includes: an arc line pattern, a polygon, and a combination pattern of the arc line pattern and the polygon.

[0043] The diversified cross-sectional shape can meet the specific needs of different welding strip products and provide design flexibility. The smoothness of the arc-shaped pattern helps to reduce stress concentration of the welding strip during the forming process. For example, the preset shape of the cross section of the shaping structure is circular or elliptical, which changes the shape of the welding strip passing through it to circular or elliptical, to meet the shape requirements in the processing process, and improve the stress concentration of the welding strip material during the forming process, thereby improving the forming quality of the welding strip and the durability of the finished product. The polygonal cross-sectional shape is usually used in the last wire drawing structure in the wire drawing link, which is used to draw the welding strip into a preset product structure shape. It is especially useful in production that requires specific angles or straight edges. For example, the preset shape of the cross section of the shaping structure is sawtooth-shaped, which changes the shape of the welding strip passing through it to sawtooth-shaped, to meet the shape requirements of the welding strip product. The sawtooth-shaped welding strip can provide a larger contact area when in contact with the battery sheet, which helps to improve the electrical conductivity and the adhesion between the welding strip and the battery sheet. At the same time, the sawtooth-shaped welding strip can better disperse and withstand the force when subjected to tension due to its shape characteristics, thereby improving the overall tensile strength. Further, the application of the combination pattern can realize the integration of multiple functional characteristics in the same welding strip product, for example, setting one end of the shape as semicircular and the other end as sawtooth-shaped, which not only meets the flexibility requirements of the welding strip, but also meets the strength requirements of the welding strip. In summary, the diversified cross-sectional design not only enhances the practicality and functionality of the welding strip product, but also improves the flexibility in the welding strip production and processing process.

[0044] Embodiment 2

[0045] Embodiment 2 of the present application provides related structures of the welding strip processing system on the basis of embodiment 1, to install the wire drawing structure in the system.

[0046] Preferably, referring to Figures 2 to 5 , the welding strip processing system further comprises at least one fixing structure 130 and at least one bracket 140; one end of the fixing structure 130 is connected with the corresponding bracket 140, and the other end is provided with a positioning structure 150; the positioning structure 150 is configured to install the wire drawing structure 100; the second end 102 of the wire drawing structure 100 is embedded in at least part of the positioning structure 150 in the installation direction, so that the end face of the first end 101 of the wire drawing structure 100 extends beyond the end face of the positioning structure 150 in the opposite direction of the installation direction.

[0047] Among them, the fixing structure 130 ensures the stability of the installation of the wire drawing structure 100, and the positioning structure 150 provides accurate positioning for the wire drawing structure 100, ensuring that the welding strip does not deviate during the wire drawing process, at the same time, the end face of the first end 101 of the wire drawing structure 100 beyond the end face of the positioning structure 150, has better guiding when the welding strip enters the wire drawing channel 110, reduces the adjustment time of the welding strip, simplifies the operation process, thereby speeding up the production speed.

[0049] Among them, the protection structure 160 ensures that the wire drawing structure 100 is not subjected to external impact or damage during the operation of the production line, prolonging its service life, and at the same time, the sleeve helps to stabilize the position of the wire drawing structure 100, preventing displacement caused by vibration or welding strip tension, ensuring the accuracy of the wire drawing process. In addition, the protection structure also improves the appearance of the wire drawing structure 100 to some extent, avoiding being exposed to the outside all the time, ensuring its neatness.

[0050] It should be noted that the protection structure 160 is actually to disperse the force received by the wire drawing structure 100, reduce the concentrated stress, and improve the durability of the overall structure, which can be adjusted according to the size of different wire drawing structures 100 and positioning structures 150.

[0051] Preferably, the protection structure 160 comprises a blocking portion 161, the sidewall of the blocking portion 161 extends in a direction perpendicular to the plane where the blocking portion 161 is located to form a surrounding portion 162; the surrounding portion 162 is arranged around the connecting end of the positioning structure 150 and the wire drawing structure 100 in the circumferential direction of the positioning structure 150, so that the blocking portion 161 abuts against the first end 101 of the wire drawing structure 100 in the mounting direction; wherein the mounting direction is parallel to the axial direction of the positioning structure 150.

[0052] The blocking portion 161 directly abuts against the first end 101 of the wire drawing structure 100, which provides a physical barrier for the wire drawing structure 100, effectively preventing direct impact or wear of the wire drawing structure 100 caused by external interference during processing and production. The surrounding portion 162 is arranged around the connecting end of the positioning structure 150 in the circumferential direction, which helps to maximize the protection area while optimizing the space utilization, making the structure more compact. The structural design of the blocking portion 161 and the surrounding portion 162 enhances the stability of the connecting end of the wire drawing structure 100 and the positioning structure 150, reduces the vibration and displacement of the wire drawing structure 100 under high speed or high load.

[0053] In some embodiments of the present application, the inner wall surface of the surrounding portion 162 is provided with an internal thread, and the outer surface of the wire drawing structure 100 is provided with an external thread, which are connected in a threaded manner.

[0059] The lubricating nozzle 172 directly sprays the predetermined lubricating liquid to the wire drawing structure 100, effectively reducing the contact friction between the welding strip and the wire drawing structure 100 during the wire drawing process, thereby reducing energy loss and material wear. By reducing friction, the welding strip can pass through the wire drawing structure more smoothly, improving production speed and overall production efficiency, while protecting the surface quality of the welding strip and avoiding damage caused by overheating due to friction.
