Electrolytic copper foil pinhole detection marking system

Abstract

The invention discloses an electrolytic copper foil pinhole detection marking system. Belongs to the technical field of electrolytic copper foil production. According to the technical key points, the device comprises a detection support, an upper mounting seat is erected on the detection support on the upper side of the electrolytic copper foil in the width direction of the electrolytic copper foil, and a plurality of industrial cameras are distributed on the upper mounting seat at intervals in the length direction; a lower mounting seat corresponding to the upper mounting seat is arranged on the detection bracket on the lower side of the electrolytic copper foil, and a light source is arranged in the lower mounting seat; two first guide rollers are arranged between the detection support and the winding roller in the horizontal direction in a spaced mode, a labeling support is arranged between the two first guide rollers, a sliding installation frame is connected to the labeling support through a horizontal driving mechanism, and the horizontal driving mechanism is arranged in the moving direction of the electrolytic copper foil. A labeling mechanism is arranged on the sliding mounting frame; the invention aims to provide the electrolytic copper foil pinhole detecting and marking system which is capable of monitoring in real time and accurately marking; the method is used for electrolytic copper foil pinhole detection marking.

Description

technical field [0001] The present invention relates to a pinhole detection system, more particularly, to an electrolytic copper foil pinhole detection and marking system. Background technique [0002] The reason for the pinholes in copper foil is that during online polishing, the friction between the polishing brush and the cathode roller will produce some impurities such as titanium oxide chips, silicon nitride particles, non-woven fibers, resin powder, etc., which enter with the polishing pure water. In the tank liquid, the overflow of the tank liquid will take away part of it into the sewage tank, and then enter the anode tank for electroplating again after being filtered, but a part will still be deposited in the anode tank. Pinholes (light-transmitting spots) are formed on the foil surface. Ultra-thin copper foil cannot avoid pinholes. [0003] At present, the number and size of pinholes cannot be directly detected in the copper foil production process. Because the p...

Ultra-thin copper foil cannot avoid pinholes

[0003] At present, the number and size of pinholes cannot be directly detected during the production process of copper foil. Because the production process is continuous, it is impossible to take samples for testing. It can only be manually sampled and tested in the darkroom after the roll is unrolled to determine the pinholes. Specific number and size of holes

This mode of operation is not only heavy workload, but also low efficiency

[0004] The company's existing production line takes 15-30 hours to produce a roll of electrolytic copper foil. The range of pinholes in the production process cannot be detected, and the robustness of the process cannot be detected.

However, in the raw foil production process, manual sampling and testing can only be carried out during roll-up and roll-off. The middle period cannot be detected, resulting in pinholes in the middle period that cannot be monitored and processed in real time, which may easily cause the entire roll of copper foil to be unqualified and increase manufacturing cost
