[0002] The copper foil defect inspection mechanism of a copper foil slitting machine is a device used to cut large rolls of copper foil into the required size and width. During the copper foil slitting process, it is necessary to check for defects. However, existing slitting workers can only inspect the front of the copper foil, and defects on the back of the copper foil cannot be detected, resulting in the loss of copper foil material. Although there are camera or scanning detection technologies on the market, their purchase and use costs are high, their compatibility is poor, and they cannot be used directly on existing equipment.
[0003] Utility model patent CN216847438U, published on June 28, 2022, discloses an online inspection device for the appearance quality of electrolytic copper foil. This device includes two light source camera systems, each comprising a first camera and a first light source, as well as a second camera and a second light source. The first camera and the first light source are mounted above the copper foil being pulled in the slitting section and facing the upper surface of the foil. The second camera and the second light source are mounted below the copper foil being pulled in the slitting section and facing the lower surface of the foil. The first camera and the second light source are vertically opposite each other. However, this online inspection device for the appearance quality of electrolytic copper foil does not solve the aforementioned technical problem. Utility Model Content

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.
[0022] like Figure 1 As shown, the copper foil defect inspection mechanism of the copper foil slitting machine includes a frame 1, a winding frame 2, and a smoothing roller 3. The frame 1 includes an inclined section 4 and a side plate 5. A fixed plate 6 is fixedly connected to the inclined section 4, and a mounting plate 7 is hinged to the fixed plate 6. A mirror 8 is provided on the mounting plate 7, and a mirror adjustment mechanism is connected to the mounting plate 7. The winding frame 2 is used to collect the copper foil roll, and the smoothing roller 3 is used to flatten the surface of the copper foil and improve its winding effect. The fixed plate 6 is welded to the frame 1. During the copper foil winding process, the operator can easily visually inspect the defects on the back of the copper foil through the mirror 8 on the frame 1. This device utilizes the reflective effect of the mirror 8, has a simple structure, requires no additional electrical equipment or control components, and has low modification and application costs. The bottom of the fixed plate 6 is connected to the bottom of the mounting plate 7 by a hinge 22, which enables the mounting plate 7 to move. The mirror 8 moves with the mounting plate 7 to achieve angle changes. The above structure has high versatility. Operators can adjust the mirror 8 to a suitable angle according to the position distribution of the winding frame 2 and smoothing roller 3 of different slitting machines, so as to adapt it for use.
[0023] like Figures 2-1 to 3 As shown, the mirror adjustment mechanism includes a sliding bolt 12, a mounting plate 7 hinged to the sliding bolt 12 with a connecting rod 14, and a mounting block 9 fixedly connected to the upper center of the fixing plate 6. The upper side of the mounting block 9 has a slotted hole 11, through which the sliding bolt 12 passes and is connected to a nut 13, which presses against the mounting block 9. A connecting lug 20 is provided on the back of the mounting plate 7, and a pin 21 is connected to one end of the connecting rod 14. The head of the sliding bolt 12 is fixedly connected to the pin 21, allowing the connecting rod 14 to move. Production personnel loosen the nut 13, controlling the sliding bolt 12 to slide on the slotted hole 11, forming a slider mechanism, thereby changing the angle of the mounting plate 7. After the mirror 8 is adjusted to a suitable angle, the nut 13 can be tightened. The operation is simple and convenient.
[0024] like Figure 5As shown, a maintenance hole 10 is provided on the side plate 5, located on one side of the mirror surface 8. A cover plate 15 is hinged to the side plate 5. The cover plate 15 is mounted on the side plate 5 via a hinge 22. The maintenance hole 10 is used to replace the mirror surface 8 or adjust the angle of the mirror surface 8. Its setting on the side plate 5 and at the same height as the mirror surface 8 does not interfere with the space of other components on the frame 1, making it convenient for operators to operate directly. During operation, the operator's body is located outside the slitting machine, and tools can be directly used to put the mirror surface 8 onto the mounting plate 7 or to loosen or tighten the nut, which improves the safety of operation and has no impact on the precision components on the slitting machine.
[0025] like Figure 1 As shown, mirror 8 is higher than the winding frame 2 and lower than the smoothing roller 3. During the smoothing and winding process of the copper foil slitting machine, the copper foil will be in a flat state between the smoothing roller 3 and the winding frame 2. Placing mirror 8 between the two reduces the difficulty for operators to inspect defects on the copper foil, which is beneficial to assist operators in visual judgment and improves the accuracy of inspection.
[0026] like Figure 2-1 As shown, the mounting plate 7 has limiting flanges 18 on both sides, and the mirror 8 is located between the limiting flanges 18. The mounting plate 7 has an installation opening 17 on the side near the inspection hole 10, and the nut 13 is located on the side of the mounting block 9 near the inspection hole 10. The limiting flanges 18 prevent the mirror 8 from falling off the mounting plate 7, improving the stability of the mirror 8 after installation. The limiting flanges 18 only occupy a local area on both sides of the mirror 8, having little impact on the overall area of the mirror 8. The installation opening 17 serves as the installation and removal port for the mirror 8, and it is opposite to the inspection door, allowing operators to directly install and remove the mirror 8 through the inspection hole 10.
[0027] like Figure 4 As shown, the cover plate 15 is provided with a handle 16 and a limiting plate 19 on one side of the inspection hole 10. The handle 16 makes it easy for the operator to rotate the cover plate 15, and the limiting plate 19 reduces the opening size of the inspection hole 10 to prevent the cover plate 15 from rotating excessively and entering the machine.
[0028] like Figure 1 As shown, there are two mirrors 8. There are two winding racks 2, each located at the bottom of the side plate 5. Each winding rack 2 is equipped with a mirror 8 to facilitate the inspection of defects in the copper foil on each winding rack 2.
[0029] When installing or replacing mirror 8, open cover 15. Production personnel can manually or with tools push mirror 8 into mounting plate 7 through inspection hole 10 along mounting opening 17. If the angle of mirror 8 needs to be adjusted, loosen nut 13 and adjust the position of sliding bolt 12 in slot 11 according to the required angle of mirror 8. During the sliding of sliding bolt 12, mirror 8 will rotate a certain angle under the action of connecting rod 14. After adjustment, tighten nut 13 and close cover 15. Mirror 8 can also be replaced with a convex mirror as needed to expand the visual inspection range.
[0030] The copper foil defect inspection mechanism of this copper foil slitting machine adds a mirror 8 to the frame 1. The mirror 8 is adjustable in angle, easy to replace, and has low maintenance safety risk. Production personnel can check the defects on the back of the copper foil after slitting through the mirror 8, which solves the cost loss caused by the inability to detect copper foil defects in time. The structure is simple, easy to install, and can be used directly on existing equipment with low modification cost.
[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
