Fiber Laser Cutting Machine with Auto Sheet Loading

Technical Solution

a. Technical Parameters:

1. This system consists of a laser cutting machine loading and unloading composite truss robot, a double-layer electric exchange trolley, a CNC control system, a vacuum control system, and other components. Together with the laser cutting machine, it forms an automated sheet metal production unit. This system automatically loads and unloads sheets, effectively improving production efficiency and reducing costs.

2. The robot is driven by a servo motor through a precision reducer, with a total lifting stroke of 700mm and a traverse distance of 5500mm (adjustable based on actual conditions).

3. Multiple sets of OPDEPO brand vacuum, oil-resistant suction cups are installed, each equipped with a manual valve for manual closing and closing according to the sheet material size. The loading robot has a repeatability accuracy of ±2mm.

4. A pneumatic sheet separation device is installed at the end to facilitate sheet separation during automatic loading. Note: Due to differences in sheet adhesion and oil content, manual assisted sheet separation can be used as needed.

5. The automatic loading and unloading system is equipped with a double-layer electric trolley (upper layer) to store finished material frames and scrap material for the laser machine after cutting, and a second electric trolley (lower layer) to supply raw material to the laser machine.

6. The trolley is driven by a reduction motor and equipped with an electromagnetic brake. It is equipped with a movable magnetic separator to facilitate sheet separation by attracting the sheet material, increasing the success rate of sheet separation.

7. The unloading mechanism utilizes a dual-fork unloading manipulator and loading suction cup connected to a single lifting column structure. This left-right dual-fork unloading mechanism shortens the unloading fork’s travel distance and reduces malfunctions.

8. The equipment is fully servo-driven. High-power servo motors drive the manipulator’s lifting and traversing operations. The lifting mechanism utilizes linear guides, ensuring high speed and positioning accuracy.

9. The control system utilizes an imported 10-inch touch screen and an intelligent CNC system with an Omron programmable controller. It features both automatic and manual operation modes. All settings, monitoring, and debugging can be performed quickly and easily via touchscreen.

10. The operating environment for this machine should meet the requirements of a temperature range of -10-45°C, a relative humidity of less than 80%, and good lighting. The environment should be free of flammable and explosive substances, strong electromagnetic interference, corrosive gases, or splashing liquids.

Technical Parameters

b. User Guide:

1. The user can switch between automatic and manual loading modes using the touchscreen to suit different working conditions.

2. Loading method: The bottom split fork opens, and the internal vacuum suction cup picks up the plate. The lifting axis lifts and moves horizontally to the laser machine, placing the sheet on the laser platform.

3. The unloading mechanism utilizes a motorized, left-right double-fork structure. The unloading forks have a short travel distance and a low failure rate. The opening and closing forks utilize steel square tube tines, which offer high load capacity and strong deformation resistance. The forks also minimize contact with the sheet, preventing scratches. The double forks open and close synchronously in both directions along linear guideways and are driven by an electromagnetic brake motor.

4. The loading and unloading robot is constructed from manganese steel pipes and high-quality steel plates welded together, treated with vibration stress relief, and machined on a large CNC gantry milling machine. It offers excellent rigidity and precision. The gantry beam and outriggers are connected by adjustment bolts, allowing for easy adjustment of the beam’s levelness. The loading and unloading robot is driven by a servo motor via a precision reducer and equipped with imported linear guides. A synchronous balancing cylinder has been added to the lifting mechanism to enhance high-speed lifting stability and prevent vibration during movement.
