What is a dual-head laser stripping machine?

The dual-head laser stripping machine is an industrial equipment used for processing wires, cables or optical fibers. It uses laser as the processing tool and precisely controls the energy of the laser to remove the external insulation layer or sheath of the cable, without damaging the internal conductor or optical fiber. The core feature of this equipment lies in its being equipped with two independent laser processing heads, which can work synchronously or asynchronously. 
I. Working Principle 
The dual-head laser stripping machine is mainly based on the principle of the interaction between laser and matter. When a high-energy-density laser beam is irradiated onto the insulation material of the cable (such as PVC, TPU, PE plastic, etc.), the material will quickly absorb the laser energy and generate a thermal effect, causing it to vaporize or decompose instantly. By precisely controlling the power of the laser, the pulse frequency, the scanning path, and the size of the light spot, the material can be removed layer by layer, forming clean and precise cuts. Since the metal conductor has a high reflectivity and low absorption rate for specific wavelengths of laser, the internal metal conductor can be well preserved. 
II. System Composition 
A standard dual-head laser stripping machine typically consists of the following core subsystems: 
Laser generator: It is the energy source of the equipment. Common types include carbon dioxide lasers or fiber lasers, which generate the laser beam needed for processing. 
Beam transmission and splitting system: The laser generator's emitted beam is guided, shaped, and distributed to two separate processing heads. The splitting system ensures that both processing heads can obtain stable and energy-identical laser beams. 
Dual processing head unit: Each processing head typically consists of a focusing lens group and a galvanometer scanning system. The galvanometer system uses high-speed deflecting lenses to control the laser beam to scan along a pre-set trajectory on the cable surface, completing circular or specific-shaped cutting. 
Motion control system: Responsible for coordinating the operation of the entire equipment, including controlling the parameters of the laser, the scanning path of the galvanometer, as well as the positioning and clamping movement of the cables and the clamping devices. 
Visual positioning system (optional but common): By using cameras, it automatically identifies the position, color or markings of the cables, ensuring the accuracy of the stripping location. It is particularly suitable for double-head asynchronous processing or scenarios with high precision requirements. 
Precision fixtures and base plate: Used to fix and position the cables to be processed, ensuring their stability during the processing. The double-head design usually corresponds to two separate processing stations. 
Software operating system: Users input processing parameters (such as stripping length, stripping depth, stripping type, etc.) through this interface and control the operation of the equipment. The software converts the instructions into signals that the control system can execute. 
Safety protection system: It includes a sealed outer cover, interlock switches, and laser protection observation windows, etc., which are used to prevent the leakage of laser radiation and ensure the safety of operators. 
III. Key Technical Features 
High precision and high quality: Laser stripping is a non-contact processing method, without mechanical stress. The cut edges are neat and free of burrs, causing no damage to the conductor. The length and depth of the stripping can be precisely controlled. 
High efficiency: The dual-head design enables the simultaneous processing of two cables, or the simultaneous processing at two different positions on the same cable, significantly enhancing production efficiency. 
High flexibility: Through software programming, different specifications and stripping requirements of cables can be quickly switched, meeting the production needs of various products in small batches. It can handle extremely thin wire diameters or special-shaped cables. 
A wide range of processing materials: Capable of handling a variety of special materials that are difficult to deal with by traditional mechanical methods, such as heat-resistant materials, elastomers, and composite materials, etc. 
Clean and environmentally friendly: During the processing, almost no debris is produced and no subsequent cleaning steps are required. 
IV. Application Areas 
The double-head laser stripping machine is widely used in industries where there are high requirements for the processing quality and efficiency of cables: 
Automotive industry: Automotive wiring harnesses, especially high-voltage cables for electric vehicles. 
Aerospace: Lightweight and highly reliable cables for aircraft. 
Medical devices: Precise wires and sensor cables inside medical equipment. 
Communication industry: High-speed data cables, RF coaxial cables and fiber optic microprocessing. 
Electronic manufacturing: Connecting wires used in precision instruments and consumer electronic products. 
The double-head laser stripping machine is a high-end processing equipment that integrates laser technology, precision machinery, automatic control and computer software. Its dual-head design not only ensures high processing quality but also effectively enhances production capacity. It is one of the key equipment in the modern precision cable processing field.
