The fully automatic dual-head terminal crimping machine consists of three main components: the motion part, control part, and execution part. According to terminal machine manufacturers, the wire harness processing equipment in the market can be roughly classified into three categories:
- Mechanical Fully Automatic Dual-Head Terminal Crimping Machine: This machine operates primarily through belts and cams to drive its motion. The advantage is its affordable price, but the downside is that mechanical parts tend to wear out and age after some usage, making maintenance and debugging quite a hassle. It has a relatively short lifespan.
- Stepper Motor Fully Automatic Dual-Head Terminal Crimping Machine: This machine is driven by stepper motors. The advantage is that it is relatively cheaper than true servo machines, resembling servo motors in appearance and having a more sophisticated design compared to mechanical models. However, the downside is that domestically produced ordinary stepper motors are prone to losing steps, affecting product accuracy, with a relatively short lifespan. Many smaller companies currently use stepper motors to impersonate servo motors, falsely claiming their products are fully servo, or combining some unknown servos with cam mechanical parts to deceive consumers.
- Fully Servo Automatic Dual-Head Terminal Crimping Machine: This machine is mainly controlled by PLC, providing servo drive signals to control the motion of servo motors. The advantages are high precision, long lifespan, and cost-effectiveness. However, the downside is the relatively high price, but the use of a motion module together significantly ensures product accuracy and lifespan.
The Role of Gearboxes:
- Gearboxes can reduce rotational inertia, generally lowering the square of the speed ratio, enabling timely control of starting, stopping, and speed changes.
- By increasing torque through gearboxes, it’s equivalent to increasing input power, reducing the power required by the input motor.
- Gearboxes protect the motor during transmission. During operation, the gearbox bears a significant torque. In case of overload, only the overload amount divided by the reduction ratio is transmitted to the motor. Directly bearing this load could lead to motor damage.
- When the motor directly connects to a load for low-speed operation, the motor needs to increase current significantly to meet the output torque, posing higher demands on motor cooling and insulation. Using a gearbox can mitigate these issues.
The Role of Motion Modules:
- Seamless and agile movement without gaps.
- Easily achieve high walking precision.
- High positioning accuracy.
- High rigidity in all directions.
- Accommodate heavy loads.
- Maintain high precision for a long time.
- Excellent high-speed performance.
In the enchanting world of terminal crimping machines, these components dance together to create the symphony of precision and efficiency.
