Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic welding ribbon slitting, and in particular to an automatic slitting device suitable for photovoltaic welding ribbons. Background Art

[0002] Photovoltaic ribbon, as the core conductive element in the solar photovoltaic industry, is more commonly known as tin-coated copper ribbon or tinned copper ribbon. This fine ribbon material plays a pivotal role in solar photovoltaic cells. It is not only a simple connector, but also a key bridge to effectively export the electrical energy converted from light energy on the silicon wafer and safely transmit it to various electrical devices. At the same time, photovoltaic ribbon also has the functions of heat dissipation and mechanical support, ensuring the stable operation of photovoltaic modules in complex and changing external environments.

[0003] The structure of photovoltaic ribbon is not simple. It is composed of high-quality copper substrate, tin alloy coating and finely added flux. These materials are cleverly combined in a precision processing process to form a composite material that is both tough and conductive. The quality of photovoltaic ribbon is directly related to the current collection efficiency and overall power output of photovoltaic modules. Therefore, every production link must be strictly controlled to ensure the excellent quality of the product.

[0004] In the production process of photovoltaic welding ribbon, slitting is a crucial process. However, in the process from unwinding to slitting device, photovoltaic welding ribbon often deviates slightly due to external force or mechanical vibration during transmission. Although this deviation is difficult to detect with the naked eye, it will directly lead to uneven width of the ribbon product after slitting, affecting the subsequent photovoltaic module assembly and current collection efficiency. Summary of the invention

[0005] In view of the technical problem in the prior art that during the slitting process of photovoltaic ribbons, slight deviations may occur due to vibrations, which affects the product quality of the photovoltaic ribbons. The purpose of the present invention is to provide an automatic slitting device suitable for photovoltaic ribbons, reduce the possibility of slight deviations of photovoltaic ribbons due to vibrations, ensure the stability of the slitting work, and guarantee the product quality of the photovoltaic ribbons.

[0006] To achieve the above object, the present invention provides the following technical solutions:

This stability is crucial to ensure the precise cutting of the ribbon and product quality.

[0023] 2. Accurate slitting effect: The slitting mechanism adopts a combination of lifting components and cutting components to achieve accurate slitting operations. With the support of the shock-absorbing base, the slitting mechanism can work in a relatively stable environment, thus ensuring the accuracy and consistency of cutting.

[0025] 4. Double-sided cleaning effect: The first air outlet is located between the conveyor chain plate and the support plate. This position allows the airflow to blow through the bottom of the photovoltaic welding ribbon to clean the dust and impurities attached to the bottom of the welding ribbon. The second air outlet is located above the support plate, higher than the height of the support plate, which means that the airflow can blow through the top of the welding ribbon to clean the dust and impurities on its top surface. This double-sided cleaning method greatly improves the efficiency and effect of cleaning.

[0026] 5. Optimized conveying mechanism: The conveying mechanism provides a stable conveying path for the photovoltaic ribbon through the design of the extension plate and the support plate. This design not only ensures the stable conveying of the ribbon, but also improves the conveying efficiency and reduces the waiting time in the production process.

[0027] 6. Improve product quality: Due to the high stability and precise slitting effect of this technical solution, the product quality of photovoltaic welding ribbons can be significantly improved. The stable transmission and slitting process reduces the damage and waste of the welding ribbons, while improving the reliability and service life of the products.

[0028] VII.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] The first embodiment is an automatic slitting device suitable for photovoltaic ribbons, such as Figure 1-2 As shown, it includes a shock-absorbing base, on which a conveying mechanism and a slitting mechanism are arranged, on which a first limiting mechanism is arranged, and on which a cleaning mechanism is arranged; the shock-absorbing base includes a mounting frame 101, on which a plurality of shock-absorbing components are fixedly arranged on the bottom periphery of the mounting frame 101; the conveying mechanism includes a conveying chain plate 201 arranged on the mounting frame 101, on each chain plate of the conveying chain plate 201 a vertical extension plate 202 is fixedly arranged, and on the extension plate 202 a horizontal support plate 203 is arranged; the slitting mechanism includes a receiving platform 301 arranged on the mounting frame 101, on which a slitting frame 302 is fixedly arranged on the top of the receiving platform 301, and the slitting frame 303 02 is provided with a lifting assembly 303, and a cutting assembly 304 is provided at the bottom of the lifting assembly 303; the first limiting mechanism includes a first limiting plate 401 arranged on both sides of the conveying chain plate 201, and both sides of the photovoltaic welding strip are in contact with the inner wall of the first limiting plate 401, and the first air outlet 402 and the second air outlet 403 are opened on the first limiting plate 401, the first air outlet 402 is located between the conveying chain plate 201 and the support plate 203, and the second air outlet 403 is higher than the height of the support plate 203; the cleaning mechanism includes a blower 501, and the air outlet of the blower 501 is connected to the first air outlet 402 and the second air outlet 403 of one of the first limiting plates 401.

[0036] like Figure 1-2As shown, the shock-absorbing base provided at the bottom of the equipment reduces the vibration that may be generated by the equipment during operation through multiple shock-absorbing components; this design can significantly reduce the impact of external vibration on the transmission and slitting process of the photovoltaic welding ribbon, thereby reducing the slight deviation of the welding ribbon caused by vibration; the extension plate 202 and the support plate 203 on the transmission chain plate 201 provide a stable transmission path for the photovoltaic welding ribbon; this design enables the welding ribbon to maintain a relatively fixed position during the transmission process, further reducing the deviation caused by vibration or other factors; the role of the first limiting mechanism: the first limiting mechanism limits the photovoltaic welding ribbon through the first limiting plates 401 on both sides, so that it can move steadily along the preset path; at the same time, the design of the first air outlet 402 and the second air outlet 403 on the first limiting plate 401 not only provides a channel for the cleaning mechanism, but also can further stabilize the position of the welding ribbon through air flow to a certain extent; blower 501 is connected with the first air outlet 402 and the second air outlet 403 of the first limiting plate 401 through the air outlet, so as to clean the dust and impurities on the photovoltaic welding strip during the slitting process; although the cleaning function itself does not directly reduce the deviation of the welding strip, keeping the welding strip clean can ensure the sharpness of the slitting blade, thereby indirectly improving the stability of slitting and the product quality; the slitting mechanism can realize precise and stable cutting operation through the combination of the lifting assembly 303 and the cutting assembly 304; due to the stability of the overall structure of the equipment and the shock-absorbing effect of the shock-absorbing base, the slitting mechanism can work in a relatively stable environment, thereby ensuring the accuracy and stability of slitting; in summary, the technical scheme effectively reduces the slight deviation of the photovoltaic welding strip caused by vibration or other factors during the slitting process through the design of the shock-absorbing base, the stable transmission mechanism, the first limiting mechanism and the cleaning mechanism, thereby improving the stability of the slitting work and the product quality.

[0037] like Figure 1As shown, the shock absorbing assembly includes a hydraulic shock absorbing rod 121, a support block 122 is arranged at the bottom of the hydraulic shock absorbing rod 121, the top edge of the support block 122 is fixedly connected to the bottom of the hydraulic shock absorbing rod 121 through a plurality of connecting rods 123, and an anti-skid pad 124 is bonded to the bottom of the support block 122; the hydraulic shock absorbing rod 121 is the core part of the shock absorbing assembly, and hydraulic oil and a piston are installed inside it; when the equipment is vibrated, the piston will move up and down under the damping effect of the hydraulic oil, thereby absorbing and converting the vibration energy and reducing the vibration transmitted to other parts of the equipment; the support block 122 is the fixed foundation of the hydraulic shock absorbing rod 121, through Multiple connecting rods 123 are fixedly connected to the bottom of the hydraulic shock absorber rod 121; the main function of the support block 122 is to provide a stable supporting surface to ensure that the hydraulic shock absorber rod 121 can work normally; the connecting rod 123 is used to connect the support block 122 and the bottom of the hydraulic shock absorber rod 121 to ensure a stable connection between the two; the provision of multiple connecting rods 123 increases the stability of the connection and prevents the hydraulic shock absorber rod 121 from shaking or falling off during vibration; the anti-slip pad 124 is bonded to the bottom surface of the support block 122 to increase the friction between the support block 122 and the ground to prevent the equipment from shifting or sliding during vibration.

[0038] like Figure 1 As shown, the lifting component 303 is configured as a lifting cylinder, and the cutting component 304 is configured as a slitting knife; the lifting component 303 adopts a lifting cylinder to realize the lifting action of the cutting component 304; the lifting cylinder generally includes a cylinder body, a piston rod and a hydraulic control system; when the hydraulic control system provides power, the piston rod will move up and down in the cylinder body, thereby driving the cutting component 304 connected thereto to lift and lower; the cutting component 304 is designed as a slitting knife, which is fixed on the piston rod of the lifting cylinder; when the piston rod of the lifting cylinder moves up or down, the slitting knife will also move up or down accordingly, thereby realizing the cutting of the photovoltaic welding strip.

[0039] like Figure 1-2As shown, a second limiting mechanism is arranged on the receiving platform 301, and the second limiting mechanism includes second limiting plates 701 arranged on both sides of the receiving platform 301, and a third air outlet 702 is opened on the second limiting plates 701, and the third air outlet 702 is higher than the height of the receiving platform 301, and the third air outlet 702 is connected to the air outlet of the blower 501; in this technical scheme, a second limiting mechanism is arranged on the receiving platform 301, and the mechanism includes second limiting plates 701 located on both sides of the receiving platform 301; these second limiting plates 701 are not only used for physical limiting to ensure the stability of the photovoltaic welding ribbon during the transmission process, but they also integrate the special design of the third air outlet 702; the third air outlet 702 is opened at the first The second limit plate 701 is located on a higher level than the receiving platform 301; when the blower 501 is working, the airflow is introduced into the third air outlet 702 through the air outlet of the blower 501 and blown out from the third air outlet 702; since the position of the third air outlet 702 is higher than the receiving platform 301, the airflow blown out from the third air outlet 702 will act downward on the photovoltaic welding ribbon; this downward airflow has two main functions: one is the cleaning function, the airflow can blow away and take away the dust and impurities on the contact surface between the photovoltaic welding ribbon and the receiving platform 301, and keep the contact surface clean; the second is the pressing function, the airflow blows the photovoltaic welding ribbon downward to make it close to the receiving platform 301, thereby reducing the transmission error caused by looseness or shaking.

[0040] like Figure 1-2 As shown, the second limiting mechanism includes a flattening roller 9 arranged above the receiving platform 301, and the flattening roller 9 is located between the second limiting plates 701, and the flattening roller 9 is used to flatten the photovoltaic welding ribbon; during the transmission of the photovoltaic welding ribbon, the flattening roller 9 will roll with the movement of the conveyor belt, thereby coming into contact with the photovoltaic welding ribbon; due to the design and material selection of the flattening roller 9, it can act on the photovoltaic welding ribbon with a certain pressure to flatten the uneven or undulating parts of its surface; such a design helps to ensure that the photovoltaic welding ribbon has a smoother surface in subsequent processing or application; at the same time, the flattening roller 9 and the second limiting plate 701 work together to form a full-range limitation and fixation of the photovoltaic welding ribbon; the second limiting plate 701 limits the lateral movement of the photovoltaic welding ribbon from both sides, while the flattening roller 9 limits its longitudinal undulation and fluctuation from the top; this full-range limitation and fixation ensures the stability and accuracy of the photovoltaic welding ribbon during the transmission process.

[0041] The second embodiment does not have a flattening roller 9, which controls the air volume of the first air outlet 402 and the second air outlet 403; when the blower 501 is working, the air volume of the first air outlet 402 is greater than that of the second air outlet 403, and the height of the photovoltaic welding ribbon changes; specifically, after the blower 501 is started, the strong airflow generated by the first air outlet 402 directly acts on the photovoltaic welding ribbon, forming an upward thrust; since the air volume of the first air outlet 402 is greater than that of the second air outlet 403, the photovoltaic welding ribbon will move upward under the push of the airflow, forming a certain gap between the ribbon and the support plate 203, which is convenient for the airflow to clean impurities in the gap.

[0042] A third embodiment, which does not have a flattening roller 9, is Figure 3 As shown, a horizontally placed first telescopic electric cylinder 6 is arranged between the first limit plate 401 and the mounting frame 101, and the blower 501 is connected to the first air outlet 402 and the second air outlet 403 through the flexible tube 502; the first telescopic electric cylinder 6 can adjust its telescopic length as needed, thereby changing the distance between the first limit plate 401 and the photovoltaic welding strip; such a design enables the first limit plate 401 to flexibly adapt to photovoltaic welding strips of different widths or heights, and provide a stable limiting effect; the blower 501 is connected to the first air outlet 402 and the second air outlet 403 through the flexible tube 502; the design of the flexible tube 502 enables the blower 501 to be flexibly connected to air outlets at different positions, while ensuring smooth transmission of airflow; the airflow generated by the blower 501 enters the first air outlet 402 and the second air outlet 403 respectively through the flexible tube 502, and then blows or cleans the photovoltaic welding strip.

[0043] like Figure 3 As shown, a horizontally placed second telescopic electric cylinder 8 is provided between the second limit plate 701 and the receiving platform 301, and the blower 501 is connected to the third air outlet 702 through the flexible tube 502; the distance between the second limit plates 701 on both sides is changed by adjusting the telescopic length of the second telescopic electric cylinder 8; such a design allows the distance between the second limit plates 701 to be precisely adjusted to accommodate photovoltaic welding strips of different widths; similarly, the blower 501 is also connected to the third air outlet 702 through the flexible tube 502; the third air outlet 702 is located on the second limit plate 701, and its design purpose is to blow away or clean the dust and impurities between the photovoltaic welding strip and the receiving platform 301; by adjusting the output of the blower 501 and the layout of the flexible tube 502, it can be ensured that the airflow can effectively reach the third air outlet 702 and play its cleaning role.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
