In the mechanical symphony of the electrolysis workshop, the stripping machine waves its silver-colored 

mechanical arm to complete the ultimate challenge of metal separation with micron-level precision. This 

equipment is like a precision surgeon in metallurgical industry, stripping thousands of copper foils with a

 thickness of only 0.05 mm from the cathode master plate every day, with an error of no more than 1/3 

of a human hair strand. the secret of the 65% increase in efficiency of the stripping process in the electrolytic

 copper production line of the world's top smelters is hidden in the intelligent control system and mechanical 

innovations of this equipment.


Mechanical revolution of stripping process


Vacuum adsorption system reconstructs the contact mechanics. The 1.2-meter diameter special suction cup 

adopts honeycomb cavity design, and the zoned pressure control system realizes 0-80kPa precise adjustment. 

When the mechanical arm contacts the cathode plate at an inclination angle of 15°, a stable negative pressure 

field is formed within 0.3 seconds, and the deviation of stripping force uniformity is controlled within ±5%.


Dynamic stress analysis optimizes the stripping trajectory. The high-frequency strain sensor monitors the stress 

change of copper foil in real time, and the industrial computer corrects the trajectory 2000 times per second. 

For different thicknesses of copper foil, the equipment automatically switches between sinusoidal, parabolic 

and other 7 types of stripping curves, reducing the metal grain boundary damage rate to 0.7%.


Temperature field regulation cracks the adhesion problem. The dual-channel temperature control system keeps 

the stripping tool at 60±2℃, and the cathode plate is preheated to 45℃, changing the thermal expansion 

coefficient of the material through a 5℃ temperature difference. This thermodynamic design reduces the bonding 

force between copper foil and titanium master plate by 40% and stripping energy consumption by 25%.


Efficiency breakthroughs with intelligent systems


The vision positioning system realizes sub-millimeter accuracy. 20 megapixel industrial camera with deep learning 

algorithm can identify the edge position of motherboard within 0.8 seconds. Six-axis robotic arm repeatable 

positioning accuracy of ±0.02mm, 30 times higher than the traditional hydraulic system, equipment crop rate 

exceeded 92%.


Digital twin technology predicts the state of the equipment. The 3D simulation system maps the data of 2,000 

monitoring points of the stripping machine in real time and predicts the tool wear trend 15 hours in advance. 

Preventive maintenance system reduces downtime to 2 hours per month and increases spare parts turnover

 by 3 times.


Flexible production modules respond to complex demands. The quick-change system can switch from 0.06mm 

to 0.15mm copper foil production in 18 minutes, and the recipe management system stores 200 sets of process 

parameters. The modularized design enables the equipment capacity to be flexibly expanded by 40%, adapting 

to the demand for multi-species production.


Innovative Practice of Green Manufacturing


The waste chip recycling system realizes zero loss. Nanoscale filtration device collects stripping dust, and pneumatic 

conveying system returns 99.97% of copper chips to the melting furnace. Each ton of cathode plate processing 

reduces copper loss by 1.2kg, saving metal value of more than 2 million yuan annually.


Energy-saving drive technology reduces energy consumption. Permanent magnet synchronous motor with energy 

feedback device reduces power consumption by 35% for a single stripping action. The standby power 

consumption of the equipment is controlled to below 200W, and the annual power saving is equivalent to

 the power consumption of 200 households.


Oil-free design shapes clean workshop. Linear motors replace traditional hydraulic systems and graphene 

coating eliminates the need for lubrication. The noise level of equipment operation is reduced to 68dB, oil 

mist emission is zero, and the operating environment is up to pharmaceutical grade cleanliness standards.


When the last piece of copper foil is peeled off, the equipment self-test system automatically generates a 

three-dimensional quality cloud map, and the data of 2,000 testing points are analyzed within 0.5 seconds. 

This multi-million dollar precision machine is reshaping the efficiency limit of electrolytic copper production 

by processing 120 cathode plates per hour. From zero-carbon factories in Northern Europe to intelligent 

workshops in Southeast Asia, the innovative iteration of electrolytic copper stripping machines continues 

to drive the metallurgical industry to evolve towards precision and cleanliness, carving a new precision

 scale on the road to metal rebirth.
