Capacitor Energy Storage in Automatic Spot Welding Machines

To further enhance the performance and reliability of the automatic spot welding machine, the capacitor energy storage system plays a crucial role. Below is an introduction to the key electromechanical energy storage components and their functions.

1. Key Components and Functions of Energy Storage

1. Triplet
   The triplet is responsible for providing a clean and stable air source to the cylinder, as well as supplying lubricating oil to maintain smooth operation. It also ensures the proper air pressure for different welding processes.

2. Control Box / Control Cabinet
   The control box is the core part of the machine’s control system. It allows operators to set welding parameters based on different materials and thicknesses, ensuring perfect welding results.

3. Solenoid Valve
   The solenoid valve controls the actuator for gas flow, facilitating the up and down movement of the cylinder. It also adjusts the speed of the cylinder’s movement and minimizes operational noise.

4. Cylinder Assembly
   This assembly is responsible for the vertical movement of the upper electrode. It applies the necessary welding pressure to the workpiece, ensuring efficient and accurate welding.

5. Push Button Switch
   The push button switch acts as the main control for welding operations. It allows operators to turn the machine on or off, as well as initiate emergency stops if needed.

Operating Instructions for the Automatic Spot Welding Machine

1. Adjustment Procedures

• Air Pressure Adjustment:
  Set the air pressure of the cylinder to the required value before beginning welding operations.

• Welding Heat Setting:
  Initially, set the welding heat to a lower value based on the material to be welded. Gradually increase it to the optimal level during welding.

• Testing:
  Conduct a tensile or tear test on the welded workpiece to ensure the weld quality is up to standard.

2. Operational Steps

1. Powering On

   • Turn on the unit’s power supply.

   • Switch on the key power switch located on the control cabinet.

2. Initial Settings

   • Set the "empty range / welding" switch to the "empty range" position.

   • Set the "manual / automatic" switch to the "manual" position on the front panel of the machine.

3. Manual Adjustment

   • Press the “Start” button to initiate manual adjustments of the electrode position, cylinder pressure, and other parameters.

4. Welding Mode

   • Once adjustments are made, switch the "empty range / welding" switch to the "welding" position.

   • Press the "Start" button to begin welding with the adjusted settings.

5. Automatic Mode

   • After the manual adjustments are complete, set the "manual / automatic" switch to the "automatic" position.

   • In automatic mode, the machine will complete the welding process with a single press of the "Start" button.

Workpiece Placement and Welding Process

• Manual and Automatic Operation:
  If the workpiece is in manual mode, the operator must press the start button step by step to complete the sequence of operations. In automatic mode, the entire process is automated after placing the workpiece.

1. Place the Workpiece:
   Place the workpiece on the lower electrode. Ensure that no other buttons are touched during placement to avoid accidents.

2. Clamping and Welding:

   • In automatic mode, the machine will automatically clamp the workpiece using the lower fixture and cylinder pressure.

   • The upper electrode will then press down, and welding will take place. After the welding cycle, the machine will return to the starting position, and the lower fixture will release the workpiece.

3. Post-Welding:
   After completing the welding process, the workpiece is released, and the system resets for the next cycle.

Safety and Operation Notes

• Always ensure that the machine is operated by a trained individual, especially during manual mode.

• Be cautious when placing workpieces, particularly cylindrical ones, to avoid accidental injury or equipment malfunction.

• Conduct regular maintenance checks on components such as the solenoid valve and cylinders to ensure optimal performance.
