The use of a patch machine
Preparatory work
Equipment inspection
Power check: Ensure that the power supply of the chip machine is properly connected and the voltage is stable.
Air source check: Check whether the air source pressure meets the requirements to ensure that the gas path is smooth.
Mechanical inspection: Check the normal operation of the mechanical arm, conveyor belt, mounting and other parts.
Material preparation
PCB preparation: Ensure that the PCB is clean, without damage, and the reference point is clear.
Component preparation: Ensure that all SMD components are complete and the feeder is properly installed.
Solder paste preparation: Ensure that the quality of solder paste is qualified and the storage conditions meet the requirements.
Program preparation
Program import: Import the mounting program into the mounter control system.
Parameter setting: According to PCB and component type, set the installation speed, precision and other parameters.
Operation procedure
PCB positioning
Input PCB: Input the PCB to the mounter through the delivery system.
Reference point recognition: The vision system recognizes the reference point on the PCB to ensure accurate positioning.
Element picking
Feeder feeding: The feeder delivers the component to the pick up position.
Pick up components: The mounting head picks up components from the feeder.
Component detection
Visual inspection: The camera detects the position, orientation and shape of the component to ensure correct pickup.
Component calibration: Adjust the component position and direction according to the test results.
Component mounting
Positioning: The mounting head places the component precisely according to the pad position on the PCB.
Mount: The mount head places the component on the PCB, usually using a vacuum nozzle or clamp.
PCB output
Output PCB: The completed mounted PCB is output through the transmission system and enters the next process.
Matters needing attention
Equipment maintenance
Regular maintenance: Clean the equipment regularly, check the wear of mechanical parts, and replace it in time.
Lubrication: Lubricate moving parts regularly to ensure smooth operation of equipment.
Operation safety
Protective measures: Wear protective equipment during operation and avoid touching moving parts.
Emergency stop: familiar with the position of the emergency stop button, stop immediately in case of abnormal situation.
Program optimization
Path optimization: Optimize the mounting path, reduce the mounting head travel distance, improve efficiency.
Parameter adjustment: According to the actual production situation, adjust the mounting speed, pressure and other parameters.
Quality control
First piece inspection: Before each batch production, the first piece inspection is carried out to ensure the quality of the mounting.
Process monitoring: In the production process, real-time monitoring of mounting quality, timely discovery and solution of problems
Common problems and solutions
Component pickup failed
Reasons: nozzle blockage, component size mismatch, feeder failure, etc.
Solution: Clean the nozzle, check the component size, repair or replace the feeder.
Mounting position deviation
Reasons: reference point identification error, PCB positioning is inaccurate, mechanical arm deviation, etc.
Solution: re-identify the reference point, adjust the PCB positioning, and calibrate the robot arm.
Component failure
Reasons: mounting pressure is too large, component quality is not qualified, suction nozzle damage.
Solution: Adjust the mounting pressure, check the quality of the components, and replace the nozzle.
