The computer of the mechanical equipment is one of the brains controlling the vertical machine. Starting, shutting down, and adjusting various parameters of the machine all rely on computer control.
When the vertical injection molding machine encounters a fault, the computer can also provide prompts. During the inspection of various parts of the machine, if no issues are found with other components, then the circuit board of the vertical injection molding machine should be checked.
Open the computer circuit board of the machine for an overall inspection to see if there are any obvious signs of damage to the circuit components. If not, then some appropriate instruments should be used for measurement.
The inspection of the circuit board mainly involves checking for any broken connections and whether any components such as resistors, electrolytic capacitors, inductors, diodes, or transistors are broken.
It is also necessary to observe whether the circuit board has been repaired before. If repairs have been made, it is important to keep track of which components were repaired.
Using an online circuit repair instrument, the circuit board can be checked. One method is to compare it with a similar, functional circuit board to identify any differences and address them immediately.
The normal maintenance of the circuit board, which is the brain commanding the vertical injection molding machine, can be divided into semi-annual and annual maintenance.
1. Semi-annual Maintenance:
(1) Clean the dust from the circuit board every quarter. You can use a specialized circuit board cleaning solution. After cleaning the dust from the circuit board, use a hair dryer to dry it.
(2) Check for any signs of overheating on the electronic components in the circuit. Check if the electrolytic capacitors have bulged or leaked. If so, they should be replaced.
2. Annual Maintenance:
(1) Clean the dust from the circuit board.
(2) Randomly inspect the capacitance of the electrolytic capacitors on the circuit board. If any capacitor’s capacitance is found to be less than 80% of its rated value, it should be replaced. Typically, the lifespan of electrolytic capacitors is around ten years, after which they should all be replaced to ensure the functionality of the circuit board.
(3) For high-power components coated with thermal grease, check if the thermal grease has dried out. If it has, remove the dried thermal grease and apply new thermal grease to prevent high-power components from burning out due to poor heat dissipation.
