Description

Technical Field

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

[0002] In the production and processing of copper foil, due to the limitations of manufacturing processes and physical effects in links such as transmission and winding, 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 adverse 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 processes such as coating and welding, the burrs may also cause problems such as uneven coating and poor welding. In severe cases, it may even lead to the fracture of the copper foil, seriously affecting the reliability and service life of the product.

[0003] In order to remove the burrs on the copper foil, cutting is a common and effective processing method. Through precise cutting processes, the burrs and uneven parts on the edges of the copper foil can be removed, improving the flatness and overall quality of the copper foil. However, the tension control of the copper foil during the cutting process is a problem that requires special attention.

[0004] In existing copper foil deburring processing devices, although a copper foil tension controller is usually equipped on the overall automated processing production line to maintain the tension stability of the copper foil during the entire transmission process, at the copper foil cutting station, there is often a lack of a dedicated tension control mechanism. This deficiency in design results in the inability to accurately monitor and adjust the tension state of the copper foil in real time at the cutting station.

[0005] During the cutting process, various dynamic factors will be introduced, such as changes in cutting speed and fluctuations in cutting force. These factors may all affect the tension of the copper foil. In the absence of a local tension controller, the tension of the copper foil is more likely to be affected by these factors, resulting in unstable tension. When situations such as tool wear and material thickness change occur during the cutting process, the tension of the copper foil may not be effectively controlled in a timely manner, thereby triggering a series of problems.

[0006] For example, if the tension of the copper foil is insufficient, it may cause the copper foil to shift or break during the cutting process, affecting the cutting quality and subsequent processing efficiency. If the tension is too large, it may cause non-permanent arc deformation or permanent deformation of the copper foil, affecting the flatness and service performance of the copper foil. In addition, inappropriate tension may also exacerbate the wear of the cutting blade, shortening its service life and increasing production costs. Summary of the Invention

Start the second motor 97. 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. Furthermore, the rotating second gear 911 can drive the sliding column 912 to move circumferentially. The circumferentially moving sliding column 912 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 an appropriate position and the spring 95 is extruded to an appropriate degree, so as to make the elastic force of the spring 95 reach an appropriate degree. During the transportation of the copper foil 10, the pressure sensor 919 can be used to detect the thrust exerted by the second connecting rod 85 on the push rod 920, which can reflect the tension of the copper foil 10 sideways. When it is necessary to increase the tension of the copper foil 10, start the hydraulic cylinder 91. The hydraulic cylinder 91 is used to push the base 92 to drive the clamping column 96 to move upward. Since the spring 95 is used to push the clamping column 96 to move outward, 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 upward movement of the push rod 920 can push the second connecting rod 85 to drive the two push blocks 84 to move upward. Thus, the upward movement of the push blocks 84 can cause the first slider 81 to drive the tension roller 82 to move outward through the connecting rod 83, so as to increase the distance between the two tension rollers 82, and further increase the tension of the copper foil 10. At the same time, the pressure sensor 919 can be used to detect the thrust exerted by the second connecting rod 85 on the push rod 920, which can reflect the tension of the copper foil 10 sideways, until the copper foil 10 reaches an appropriate tension;

[0042] Step 3: During the process of increasing the tension of the copper foil 10, if the monitored value of the pressure sensor 919 deviates, or the pressure sensor 919 fails and cannot accurately detect the thrust exerted by the second connecting rod 85 on the push rod 920. For example, when the copper foil 10 reaches an appropriate tension and the hydraulic cylinder 91 continues to push the base 92 upward due to the failure of the pressure sensor 919. At this time, the thrust exerted by the second connecting rod 85 on the push rod 920 is greater than the elastic force of the spring 95. Thus, when the base 92 continues to move upward, under the extrusion of the bottom end of the clamping seat 916, the clamping column 96 can be made to move into the inner cavity of the extrusion groove 94 and squeeze the spring 95 to cause elastic deformation until the clamping column 96 separates from the bottom end of the clamping 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 clamping seat 916 until the base 92 presses the button switch 918, causing the hydraulic cylinder 91 to close, so as to prevent the copper foil 10 from being torn or damaged due to excessive tension.

[0043] The device realizes precise adjustment of the copper foil tension at the cutting station, effectively solving the problems of offset, fracture, deformation and other defects of the copper foil during cutting in the prior art. The device not only significantly improves the cutting quality of the copper foil and the subsequent processing efficiency, but also prolongs the service life of the cutting blade, reduces the production cost, and provides an efficient and reliable solution for the precision processing of the copper foil.
