Patent: A convenient laser welding machine

1. Technical field and background technology:

Briefly describe laser welding technology and its applications (such as precision manufacturing, electronics, medical devices, jewelry, mold repair, etc.).

Identify the common drawbacks of current laser welding equipment (especially industrial grade), such as large and bulky size, need for fixed installation, high requirements for working environment (such as power supply and cooling), complex operation, and high cost.

Emphasize that existing technologies are unable to meet the needs of outdoor operations, on-site maintenance, small studios, mobile processing, and other scenarios.

2. Purpose of Invention:

The purpose of the present invention is to provide a laser welding machine that is compact in structure, lightweight, and easy to carry and operate.

Overcoming the drawbacks of bulky equipment, inconvenient mobility, and limited usage scenarios in existing technologies.

This may also include improving operational convenience, lowering usage barriers, and enhancing the applicability of specific scenarios such as fine welding.

2. Technical solution (core content):

Overall structural design:

Integrated design: Highly integrate core components such as laser, control system, cooling system (if any), power supply (possibly with built-in battery) into a compact box or frame. The patent will provide a detailed description of how each component is arranged to minimize volume and weight.

Lightweight materials: The shell and frame are made of lightweight materials such as aluminum alloy and high-strength engineering plastics.

Portable design: includes accessories such as handles, shoulder straps, rollers, etc. that are easy to carry manually or move over short distances. It may be designed in the form of a toolbox, suitcase, or small cart.

3. Laser selection:

The key to achieving portability is to choose small-sized and high-efficiency lasers. Common choices include:

Fiber laser: high efficiency, good beam quality, relatively small size, maintenance free (or low maintenance), is currently the mainstream choice for portable laser welding machines.

Semiconductor lasers: smaller in size and higher in efficiency, but may have slightly lower beam quality and power density than fiber lasers, making them suitable for specific precision requirements.

Pulsed Nd: YAG laser (early): also used in portable devices, but not as bulky and efficient as fiber lasers.

The patent will clearly specify the type, power range (usually lower power, such as 50W-1500W, sufficient for fine welding and thin plate welding), and integration method of the selected laser.

4. Cooling system:

Miniaturization/efficient cooling: Traditional water cooling systems have a large volume. The portable solution may adopt:

Micro air cooling system: For low to medium power lasers, efficient and compact fan cooling may be feasible.

Miniaturized water cooling/semiconductor refrigeration: In situations where stronger heat dissipation is required, an integrated water cooling cycle system or thermoelectric cooler with significantly reduced volume and weight is used.

Natural cooling (low-power): Extremely low-power devices may rely solely on heat sinks and natural convection.

5. Power system:

Wide voltage input/built-in battery: Supports universal AC input (such as 100-240V AC).

Key innovation point (important): It may include a built-in rechargeable lithium battery pack, which is the core of achieving true "wireless" portability and outdoor operations. The patent will describe the type of battery (such as lithium-ion), capacity, battery life, charge and discharge management circuit, and how to integrate it safely.

6. Control system:

Integration and Simplification: Integrating laser control, motion control (if including simple fixtures or mirrors), and human-computer interaction into a compact control panel or touchscreen.

Intelligent/preset program: may include preset welding parameters and simple programming functions to reduce operational difficulty.

Wireless connection (optional): Supports Bluetooth/WiFi connection to mobile apps or tablets for remote monitoring and parameter settings.

7. Beam transmission and processing head:

Lightweight handheld welding gun/processing head: Designed as a lightweight and ergonomic handheld welding head, laser is transmitted through flexible fiber optics (fiber laser). The welding gun integrates collimating/focusing lenses, protective gas interface (optional), indicator light (red/blue light), and may also have a simple wire feeding mechanism (optional).

Simple fixing device (optional): may come with small, foldable, or quick to install simple workpiece fixing fixtures, suitable for mobile environments.

8. Safety protection:

Integrated security measures: Although portable, security is crucial. Including key switch, emergency stop button, laser protective goggles (standard or interface), protective cover (processing area), laser start stop indicator, safety interlock, etc. Patents will describe how to implement necessary safety features in compact designs.

9. Innovation points/beneficial effects:

Significantly improved portability: significantly reduced weight and volume, making it easy for a single person to carry and move.

Flexible operating scenarios: It can be used in various environments such as workshops, outdoors, on-site, high-altitude, and small workbenches, freeing itself from the limitations of fixed workstations.

Easy to use: Integrated control system, user-friendly interface, reducing the requirement for professional skills of operators.

Quick response: convenient for on-site maintenance, emergency response, and small-scale production.

Reduce usage costs: Reduce reliance on large fixed equipment and dedicated sites.

Improve efficiency in specific scenarios: There are significant efficiency advantages in areas such as mold repair, precision parts welding, jewelry processing, and electronic maintenance.

Wireless operation capability (such as including batteries): achieving true unrestricted operation, especially suitable for power free environments or scenarios that require frequent movement.
