Common Failures and Solutions of Automatic Wire Terminal Crimping Machines

Automatic Wire Terminal Crimping Machine (AWTCM) is becoming increasingly popular in electronic wiring harnesses.

Below are some common problems, causes, and solutions related to AWTCM:

Issue: The machine cannot start or stops during operation.
Solution:

a. Check for power input (220V) and 6KG air pressure.

b. Verify if the set total quantity has been reached. If reached, reset it, then power off and restart.

c. Inspect for wire jamming or any obstructed moving parts in the machine.

d. Ensure proper signal and power connections to prevent machine malfunction.

Issue: Mild noise during AWTCM operation is normal, but excessive noise may indicate:
a. Wear between certain parts causing increased friction.

b. Loose screws during operation leading to greater component vibrations.

Solution:

a. Apply more lubricating oil.

b. Replace worn-out parts.

c. Perform tightening procedures.

Issue: Poor terminal detection or no sensing.
a. Optical fiber probe misalignment.

b. Improper adjustment of detection distance resulting in faulty detection.

c. Sensor damage.

d. Missing terminal detection system deactivated.

Solution:

a. Adjust the probe to align with the path of terminal passing.

b. Re-adjust the distance between the detection head and the terminal.

c. Check for sensor damage and consider replacement if necessary.

d. Verify if the missing terminal detection is enabled on the operating interface.

Regular pre-operation checks and cleaning of AWTCM equipment daily can prevent most faults. Thorough inspection and cleaning before operation are crucial. A malfunction in one area can affect the normal operation of other parts, exacerbating the issue. Thus, prompt maintenance is essential upon detecting abnormalities to minimize disruptions in production or unnecessary losses. Additionally, daily cleaning and periodic maintenance are equally vital for sustained performance.
