Description

Technical Field

[0001] The utility model relates to a glossiness detection device, and more specifically, to an online glossiness detection device for copper foil. Background Art

[0002] As one of the important raw materials for the negative electrode current collector of lithium batteries, electrolytic copper foil is not only light, thin, high in energy density, high in tensile strength, high in elongation and low in roughness, but its glossiness also determines whether the copper foil can be used commercially. Glossiness that meets the standard means that the surface quality of the copper foil roll is good. It also shows that the copper grains are deposited evenly and densely during the electrodeposition process, which also indirectly reflects that the foil production system is in good operating condition.

[0003] Currently, the surface glossiness data of copper foil on a foil production machine is obtained by manually measuring and recording it using instruments at regular intervals. This manual measurement method cannot obtain data continuously in real time, and cannot promptly detect abnormal fluctuations in the foil production machine. The test distance is difficult to control and may press on the copper foil surface, affecting the apparent quality of the copper foil. It is also easily affected by changes in external light. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the above-mentioned prior art and to provide a copper foil online glossiness detection device which has a simple structure, is real-time and continuous, and reduces external light interference.

[0017] See Figure 1-3As shown, the present invention provides an online copper foil gloss detection device, comprising a frame 1 of a foil machine, with light shields 2 provided on the frame 1 on both sides of one of the conveyor rollers of the foil machine. A mounting frame 3 is provided on the light shield 2 located on one side of the copper foil, a position adjustment assembly 4 perpendicular to the copper foil surface is provided between the mounting frame 3 and the light shield 2, and a gloss detector 5 is provided within the mounting frame 3. By providing the gloss detector on one side of the copper foil via the position adjustment assembly, the gloss of the copper foil produced by the foil machine can be detected in real time. The distance between the gloss detector and the copper foil surface can also be adjusted to avoid pressing on the copper foil surface, thereby ensuring the apparent quality of the copper foil. Furthermore, by providing light shields on both sides of the copper foil to block external light sources, the gloss detector is prevented from being interfered with by external light, thereby ensuring the accuracy of the detection.

[0018] In this embodiment, the inner surface of the light shield 2 is provided with an anti-reflective layer. The inner surface of the light shield is frosted or sprayed with matte paint to prevent light from entering the reflector through the gap at the light shield opening and being reflected to the gloss detector to affect the detection.

[0019] In this embodiment, a shock-absorbing assembly 6 is installed on the mounting frame 3 to reduce vibration of the gloss meter 5. The foil production machine experiences slight vibrations during operation, which can cause the gloss meter to wobble slightly, affecting the testing process and potentially causing the gloss meter to contact the copper foil surface. By installing a shock-absorbing assembly on the mounting frame, the gloss meter remains stable, eliminating the transmission of vibration.

[0020] Furthermore, the shock-absorbing assembly 6 preferably includes a rubber layer 6a disposed on the inner wall of the mounting frame 3, which covers the sidewalls of the gloss meter 5. A shock-absorbing spring 6b is connected to the position adjustment assembly 4 on the outer wall of the mounting frame 3. The shock-absorbing spring 6b has 0.8-1.4 turns. The shock-absorbing spring, with a large diameter and small number of turns, provides primary vibration damping between the position adjustment assembly and the mounting frame. The rubber layer covering the outer surface of the gloss meter then provides secondary isolation from vibration, effectively ensuring the stability of the gloss meter.

[0021] In this embodiment, the frame 1 is preferably provided with a plurality of crossbeams 7 for mounting the light shield 2, with cushioning pads 8 disposed between the crossbeams 7 and the light shield 2. Both the crossbeams 7 and the light shield 2 are provided with through-holes, within which fastening bolts 9 are disposed for securing the crossbeams 7 to the light shield 2. The fastening bolts 9 are coated with shock-absorbing cotton 10. With this structure, the cushioning pads and shock-absorbing cotton effectively reduce the transmission of frame vibration to the light shield, thereby reducing vibration to the gloss tester mounted on the light shield and maintaining stability.

[0022] In this embodiment, the position adjustment assembly 4 comprises two mounting plates 4a symmetrically positioned on the light shield 2 and perpendicular to the copper foil surface. Each mounting plate 4a is equipped with an adjustment rail 4b, which in turn is supported by a sliding seat 4c. The mounting frame 3 is connected to each sliding seat 4c at either end. An adjustment screw 4d is provided between the adjustment rails 4b and the sliding seat 4c. By moving the sliding seat with the adjustment screw, the distance between the gloss tester and the copper foil surface can be adjusted to accommodate testing of copper foils of varying thicknesses.

[0023] Furthermore, in this embodiment, since the mounting frame and the sliding seat are connected via a damping spring, a gap exists between them. A light shield, no less than the length of this gap, is installed on one end of the sliding seat to prevent external light from entering between the gloss meter and the copper foil. Furthermore, with this structure, the angle of the gloss meter can be adjusted within a certain range by adjusting the position of one side of the sliding seat.

[0024] During operation, the position of the gloss tester is adjusted by adjusting the screw according to the thickness of the copper foil produced by the foil machine, so that the gloss tester is at an appropriate detection distance from the copper foil surface. The copper foil is transported into the light shield on the foil machine and the gloss tester is used to detect the gloss in real time.

[0025] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
