Description

Technical Field

[0001] The invention relates to the technical field of copper foil processing, in particular to a cutting device for processing and producing conductive copper foil materials. Background Art

[0002] During the production and processing of copper foil, due to the limitations of the manufacturing process and the physical effects in the transmission and winding process, burrs often form on the edges of the copper foil. These burrs not only affect the appearance quality of the copper foil, but more importantly, they may cause a series of undesirable phenomena in the subsequent applications of the copper foil. For example, the burrs will increase the contact resistance between the copper foil and the circuit board or other materials, affecting the performance of the circuit. In the coating and welding processes, the burrs may also cause problems such as uneven coating and poor welding. In severe cases, they may even cause the copper foil to break, seriously affecting the reliability and service life of the product. In order to remove the burrs on the copper foil, cutting is a common and effective processing method. Through the precise cutting process, the burrs and uneven parts on the edge of the copper foil can be removed, and the flatness and overall quality of the copper foil can be improved. However, the tension control of the copper foil during the cutting process is an issue that requires special attention. In the existing copper foil deburring processing device, although the overall automated processing line is usually equipped with a copper foil tension controller to maintain the stability of the copper foil tension during the entire transmission process, there is often a lack of a dedicated tension control mechanism at the copper foil cutting station. This design deficiency results in the inability to accurately monitor and adjust the copper foil tension state in real time at the cutting station. The cutting process will introduce a variety of dynamic factors, such as changes in cutting speed, fluctuations in cutting force, etc. These factors may affect the tension of the copper foil. In the absence of a local tension controller, the tension of the copper foil may be more susceptible to these factors, resulting in unstable tension. When the tool wears or the material thickness changes during the cutting process, the tension of the copper foil may not be effectively controlled in a timely manner, which in turn causes a series of problems. For example, if the tension of the copper foil is insufficient, it may cause the copper foil to deflect or break during the cutting process, affecting the cutting quality and subsequent processing efficiency; if the tension is too large, it may cause the copper foil to have non-permanent arc deformation or permanent deformation, affecting the flatness and performance of the copper foil. In addition, inappropriate tension may also aggravate the wear of the cutting blade, shorten its service life, and increase production costs. Summary of the invention

The output end of the first motor 79 rotates to drive the active bevel gear 711 to rotate through the first connecting rod 710, and the active bevel gear 711 rotates to drive the first rotating rod 71 to rotate through the driven bevel gear 78, and then the rotation of the first rotating rod 71 can drive the rotating drum 74 to rotate through the cooperation between the second slide groove 72 and the second slider 73, and the rotation of the rotating drum 74 can drive the cutting circular knife 75 to rotate, so that the rotating cutting circular knife 75 can be used to cut and remove the burrs of the copper foil 10 being conveyed; Step 2: According to the maximum tension of the copper foil 10 grams being transported, the extrusion degree of the spring 95 is adjusted, so that the elastic force of the spring 95 can be adjusted, and the second motor 97 is started. The output end of the second motor 97 can drive the first gear 99 to rotate through the third connecting rod 98. The rotation of the first gear 99 can cause the second gear 911 to rotate, and then the rotating second gear 911 can drive the slide post 912 to move along the circumferential direction. The slide post 912 moving along the circumferential direction can cooperate with the push plate 913 to cause the push plate 913 to push the baffle 914 to move along the inner cavity of the extrusion groove 94 until the baffle 914 moves to a suitable position, and the spring 95 is squeezed to a suitable degree, so that the elastic force of the spring 95 reaches a suitable degree. In the process of conveying the copper foil 10, the pressure sensor 919 can be used to detect the pressure applied by the second connecting rod 85 to the push rod 920. The thrust can reflect the tension of the copper foil 10 from the side. When the tension of the copper foil 10 needs to be increased, the hydraulic cylinder 91 is started, and the hydraulic cylinder 91 is used to push the base 92 to drive the clamping column 96 to move upward. Since the clamping column 96 is pushed outward by the spring 95, when the clamping column 96 moves upward, the clamping column 96 can be used to push the clamping seat 916 to drive the push rod 920 to move upward. The push rod 920 moves upward and can push the second connecting rod 85 to drive the two push blocks 84 to move upward. The push block 84 moves upward and can drive the first slider 81 to drive the tension roller 82 to move outward through the connecting rod 83, thereby increasing the distance between the two tension rollers 82, thereby increasing the tension of the copper foil 10. At the same time, the thrust applied by the second connecting rod 85 to the push rod 920 detected by the pressure sensor 919 can reflect the tension of the copper foil 10 from the side until the copper foil 10 reaches a suitable tension. Step 3. When increasing the tension of the copper foil 10, if the monitoring value of the pressure sensor 919 deviates, or the pressure sensor 919 fails and cannot accurately detect the thrust applied by the second connecting rod 85 to the push rod 920, such as when the copper foil 10 reaches an appropriate tension, the hydraulic cylinder 91 continues to push the base 92 to move upward due to the failure of the pressure sensor 919. At this time, the thrust applied by the second connecting rod 85 to the push rod 920 is greater than the elastic force of the spring 95, so that the base 92 continues to move upward. Under the pressure of the bottom end of the card seat 916, the card column 96 is forced to move toward the inner cavity of the extrusion groove 94, and the spring 95 is elastically deformed until the card column 96 is separated from the bottom end of the card seat 916. At this time, the hydraulic cylinder 91 continues to push the base 92 upward, causing the base 92 to move upward along the inner cavity of the card seat 916 until the base 92 presses the button switch 918, causing the hydraulic cylinder 91 to close, thereby preventing the copper foil 10 from being torn or damaged due to excessive tension.
