Description

Technical Field

[0001] The utility model relates to the technical field of production of electrolytic copper foil, in particular to a dust sticking device for a copper foil slitting machine. Background Art

[0002] Electrolytic copper foil is a kind of metal copper foil produced by electrolysis with copper as the main raw material. It is an important material for the manufacture of copper clad laminate (CCL), printed circuit board (PCB), and lithium-ion battery. The product is widely used in new energy vehicle power batteries, energy storage equipment and electronic products, copper clad laminate, printed circuit board and other fields.

[0003] In the field of production technology, the production process of electrolytic copper foil mainly covers four major links: liquid preparation, raw foil, surface treatment, and slitting. The goal of the slitting link is to accurately trim the width of the copper foil according to customer needs. After slitting, the appearance of the copper foil needs to be evaluated by the quality control end, including dust detection. Dust detection is a basic appearance detection method. The operation process is as follows: use white sticky paper to adhere to the surface of the copper foil, then cover it with a film, and use a magnifying glass to check whether there are abnormal foreign matter such as copper powder, copper wire, copper chips, fiber filaments, black spots, etc. The current dust detection method is manual operation. The quality inspector holds the sticky paper in hand and touches the surface of the copper foil for sticky sampling. The sampling process is prone to insufficient adhesion, which may lead to inaccurate test results. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] See also Figure 1A preferred embodiment of a dust sticking device for a copper foil slitting machine is disclosed. In this embodiment, the dust sticking device for the copper foil slitting machine includes a smooth dust sticking roller and a matte dust sticking roller. The smooth dust sticking roller and the matte dust sticking roller are directly mounted on the slitting machine table of the slitting machine. The two are arranged opposite to each other, and the gap between the rollers is used as the material passing gap of the copper foil after slitting. When the copper foil 4 passes through this gap, its corresponding smooth surface faces up and the matte surface faces down, and it will contact the smooth dust sticking roller on the upper surface and the matte dust sticking roller on the lower surface, thereby achieving automatic adhesion.

[0020] The smooth surface sticky roller and the rough surface sticky roller have similar roller structures, both of which include a roller surface, a roller body and a roller shaft, which correspond to Figure 1 The smooth sticky roller surface 1, the smooth sticky roller body 2, the smooth sticky roller shaft 3, the rough sticky roller surface 7, the rough sticky roller body 6 and the rough sticky roller shaft 5, the smooth sticky roller shaft 3 and the rough sticky roller shaft 5 are all assembled as driven structures, the smooth sticky roller body 2 and the rough sticky roller body 6 are respectively sleeved on the corresponding smooth sticky roller shaft 3 and the rough sticky roller shaft 5, and the smooth sticky roller surface 1 and the rough sticky roller surface 7 are adhered to the corresponding smooth sticky roller body 2 and the rough sticky roller body 6.

[0021] The smooth sticky roller body 2 and the matte sticky roller body 6 are both made of stainless steel with smooth surfaces and no impurities, while the smooth sticky roller surface 1 and the matte sticky roller surface 7 are made of rubber with a certain surface roughness to have a certain adhesion.

[0022] A smooth sticky paper 8 is fixed on the outer side of the smooth sticky roller surface 1, and a rough sticky paper 9 is fixed on the outer side of the rough sticky roller surface 7. The surfaces of the smooth sticky paper 8 and the rough sticky paper 9 are formed with sticky material layers with different viscosities, which can be selected according to the surface characteristics of the corresponding copper foil to be detected; both the smooth sticky paper 8 and the rough sticky paper 9 adopt a paper roll structure, which is convenient for replacement. At the same time, a pre-tear seam is formed on the smooth sticky paper 8 and the rough sticky paper 9, so that when replacing the sticky paper, it can be easily torn along the pre-tear seam to improve the replacement efficiency; in this embodiment, the tearable area corresponding to the pre-tear seam has a specification of 30cm*150cm. This specification is selected to meet the convenience and efficiency of replacing the sticky paper in actual operation. Of course, this specification can be appropriately adjusted according to actual needs.

[0023] In another embodiment, a pressing device may be optionally provided on the smooth sticky roller and / or the rough sticky roller, and the pressing device may be used to adjust the pressing force between the smooth sticky paper 8 and the copper foil 4, and between the rough sticky paper 9 and the copper foil 4 surface by adjusting the pre-pressure acting on both ends of the smooth sticky roller shaft 3 and / or the rough sticky roller shaft 5, so as to ensure that the corresponding smooth sticky paper 8, rough sticky paper 9 and the copper foil 4 surface can fully contact, thereby improving the adhesion effect. Specifically, an adjustable force-applying structure may be provided at both ends of the smooth sticky roller shaft 3 and / or the rough sticky roller shaft 5, and the force-applying structure may be an electric structure or a pneumatic structure or a pressure spring with a fixed elastic coefficient, and the force-applying direction is the direction of the axis connecting the smooth sticky roller shaft 3 and the rough sticky roller shaft 5.

[0024] In actual application, when the copper foil 4 passes through the roller gap between the smooth sticky roller and the matte sticky roller, the smooth sticky paper 8 and the matte sticky paper 9 will adhere to the smooth upper surface and the matte lower surface of the copper foil respectively, thereby achieving full adhesion of foreign matter on the surface of the copper foil 4. Due to the design of the smooth sticky roller and the matte sticky roller, the sticky paper can more fully adhere to the surface of the copper foil, thereby improving the efficiency and accuracy of sampling, and avoiding the problems of insufficient sampling and inaccurate test results that may exist in the detection process caused by traditional manual dust sticking.

[0025] After each mother roll is unrolled, the operator can tear off the smooth sticky paper 8 and the rough sticky paper 9 after sampling through the pre-tear seam, and obtain the white sticky paper after sampling that can be used for appearance inspection.

[0026] In addition, in order to facilitate the detection and adjustment of the dust sticking effect, the utility model can also be equipped with a corresponding detection mechanism and control system. The detection mechanism can use photoelectric sensors, cameras and other equipment to monitor and record the dust sticking situation on the copper foil surface in real time. The control system can adjust the driving device accordingly according to the feedback signal of the detection mechanism, thereby achieving accurate control of the dust sticking effect.
