(Summary description)SMT mounter maintenance plan SMT mounters should have a regular inspection and maintenance system.   1. Daily inspection (1)Before turning on the power of the mounting machine, check the following items. ① temperature and humidity: temperature between 20 ℃ ~ 26 ℃, humidity between 45 ~ 70%. ② Indoor environment: require clean air, no corrosive gas. ③Convinced that there is no debris on the transmission rail and within the moving range of the mounting head. ④Check that there is no debris on the fixed camera and that the lens is clean. ⑤ Make sure that there is no debris around the nozzle bank. ⑥Check that the nozzles are not dirty or deformed and clean or replace them. (vii) Check that the tape feeder is correctly positioned in the station and that there is no debris on the station. (8) Check the connection of the air connections, air hoses etc. (2) Check the following items after turning on the power to the labelling machine. If the machine is not operating correctly, an error message will be displayed on the monitor. (1) After booting the system, check that the menu screen is displayed properly. ② Press the "Servo" switch and the indicator light should be on. Otherwise, switch off the system, restart it and turn it on again. ③If the emergency switch is working properly. ④Check whether the mounting head can return to the starting point (source point) correctly. ⑤Check whether there is abnormal noise when the mounting head moves. ⑥Check that the negative pressure of the suction nozzle of all the mounting heads is within the measuring range. ⑦ Check that the PCB runs smoothly on the guide rails. Check whether the sensor is sensitive. ⑧Check whether the side positioning and needle positioning are correct. 2. Monthly check (1) Clean the screen of the CRT and the floppy disk drive (2) X and Y axes - make sure there is no abnormal noise in the X and Y axes when the attaching head is moving. (3) Cables - Ensure that there are no loose screws on the cables and cable brackets. (4) Air connectors - make sure that the air connectors are not loose. (5) Air hoses - Check the tubes and connections. Be satisfied that there are no leaks in the air hoses. (6) X and Y motors - Be sure that the X and Y motors are not abnormally hot. (7) Overtravel alarm - Move the attachment head in the positive and negative directions along the X and Y axes. When the mounting head is moved out of its normal range, an alarm should sound and the mounting head can stop moving immediately. After the alarm, use the manual operation menu to make sure the mounting head can operate. (8) Rotating motor - check that there is no dirt on the timing drive belt and gears. Ensure that the placement head can be rotated without obstruction. Ensure that the head has sufficient torque. (9) Z-axis motor - check that the placement head can move smoothly up and down. Push the nozzle upwards with your finger to see if it moves smoothly. Move the head up and down out of its normal range, check that the alarm sounds and that the head stops immediately. (10) S-motor (if there is a scanning CCD) one by one make sure that the scanning head moves smoothly. (11) Negative pressure - check the negative pressure of all placement heads. If the negative pressure value is not normal, clean the filter in the nozzle shaft and if the filter in the vacuum discharge tube is dirty (blackened), replace it. (12) Transfer guide - Check the movement of the transfer guide. Check the tightness of the conveyor belt. Check that the conveyor belt is free of stains, scratches and debris. Check the automatic width adjustment of the guide rails. Check movement when adjusted to *large and *small widths. Check the parallelism of the guide rails and the transfer of the PCB at the population and exit points. (13) PCB limiter - check its movement and noise. (14) Side clamping, rear top block, buffer block - check their wear. (15) Clamps on the nozzle bank - check for flexibility and wear. (16) Cameras - clean all camera lenses and light boxes. (17) Camera lighting unit - check its movement and brightness. (18) Operating switches - check that all brakes are working properly on the VO signal screen. Check the emergency stop switch. (19) Warning lights - Make sure all lights are illuminated. Make sure they are all securely mounted. (20) Danger alarms, warning alarms - check that they are working. (21) Camera - carry out a "picture check". (22) Pick-up point coordinates - check the pick-up point coordinates of the feeder station. (23) Placement position - make sure that the components can be assembled to the specified location. The SMT mounter maintenance schedule is described.
