Automated optical inspection machine (AOI) is a new type of testing technology. It has developed very rapidly in recent years. The structure of AOI consists of four parts: workbench, CCD camera system, electromechanical control and system software. When testing, firstly, the circuit board to be tested is placed on the workbench of the AOI machine, and the detection procedure of the product to be detected is called out through positioning. The X/Y workbench will send the circuit board under the lens according to the command of the setting program. With the help of the special light source, the lens will capture the image required by the AOI system and analyze it, then the processor will move the lens toward the lens. The next position is collected for the next image and then analyzed, and the image is subjected to continuous analysis and processing to obtain a higher detection speed. The process of AOI image processing essentially digitizes the extracted image, and then compares it with the pre-stored “standard”. After analysis and judgment, it finds the defect to make a position prompt, and at the same time generates image text, and the operator further confirms or sends the repair station. Overhaul.
Why Use AOI ?
AOI plays a full role in the miniaturization, high-density, rapid assembly, and diversified development of SMT. The amount of information detected is large and complex, both in terms of real-time detection and feedback, and in the analysis and diagnosis of correctness. The era of manual visual inspection is gone forever. The intelligent development of AOI technology is bound to become an inevitable development trend.

1. Daily maintenance is carried out by the operator of the production department. The maintenance contents are as follows:
a. Clean the surface of the machine casing;
b. Clean the dust on the display screen and the surface of the keyboard and mouse;
c. Clean foreign objects on both sides of the track to prevent unnecessary debris from falling into the machine;
d. Check if the static wire is well grounded.
2. Weekly maintenance is arranged by the technician for maintenance. The maintenance contents are as follows:
a. Check the operation of the lead screw and the guide rail;
b. Check the parallel condition on both sides of the track and the tension of the clip;
c. Check the operation of the motor, whether it is hot or abnormal, etc.;
d. Check the finishing status of the program and the SPC misjudgment status statistics of each model.
3. The monthly maintenance is carried out by the technicians during the month. The maintenance contents are as follows:
a. Check the usage status of the program and make backup updates in time;
b. Check the lubrication of the rotating part of the electric motor and clean it in time;
c. Check if the brightness of the light source is good. If necessary, do camera calibration.
d. Check all belt drive and belt tension;
e. Clean the cooling fan filter cotton.
Maintenance itemIn order to make the equipment work properly and extend the life of the equipment, please perform the following regular maintenance work:
After the end of the day, turn off the power of the computer and the machine, vacuum the dust on the machine surface and wipe the dust on the surface of the device with a white cloth. Note: Do not use organic solvents to scrub the surface of the machine as it may damage the surface paint. Never use a wind gun. The air gun will blow dust and debris into the machine and attach it to the screw, rail or lens. Affect the normal operation of the machine.
For maintenance of the screw and guide rails every 1 month, first clean the oil with a clean white cloth, then use the 10-11 oil brush to evenly apply the grease to the surface of the screw and the guide rail. Note: Grease and lubricant must be of good quality. Otherwise, the surface friction of the screw or the guide rail will be increased, thereby shortening the service life of the lead screw and the guide rail, and affecting the accurate positioning of the machine. Recommended: Germany OKS premium grease OKS422, or refer to the grease used in the maintenance of the placement machine.
Clean the filter cotton on the left side of the industrial computer panel every 1 month.
Perform a calibration of the light source every 6 months. Because the brightness of the LED light may change slightly after half a year, in order to ensure the normal test, the light source needs to be verified once.
Packing & Delivery
Can be exported according to customer requirements fumigation wooden box or standard inspection-free wooden box
The wooden box is packed in tin foil and vacuumed to achieve a waterproof and moisture-proof effect.
The machine fixes each corner with foam to prevent the impact from being affected during transportation.
