The core production equipment in the SMT production process is the SMT pick and place machine. All production equipment is developed around the SMT pick and place machine. At the same time, the SMT pick and place machine is also a sophisticated automated production equipment, which is equivalent to a robot. If the pick and place machine fails, all the work in the SMT production workshop can only be stopped, so the operation of the SMT pick and place machine must memorize the operation precautions. Charmhigh Electromechanical's high-end domestic pick and place machines share the precautions and details of the SMT pick and place machine operation here. have those?
First,what are the precautions and details for the operation of the SMT pick and place machine?
1. Check whether there are impurities and foreign objects inside the SMT pick and place machine, and clean them in time if there are any;
2. Check whether the feeder is placed abnormally;
3. Check whether the nozzle configuration status is abnormal;
4. Check whether the safety shield is abnormal;
5. Check whether there are unsafe safety hazards around the equipment;
6. First, according to the safety technical operation specification of SMT equipment, the SMT pick and place machine power supply, check whether the air pressure and rated voltage are normal, and then turn it on;
7. Secondly, we need to check whether the vacuum pressure of the SMT pick and place machine meets the requirements of the equipment. The vacuum value of the pick and place machine is usually around 5.5bar;
8. Turn on the pick and place machine servo system;
9. Return the x and y axes of the pick and place machine to the initial position of the source point;
10. According to the width of the pcb circuit board, adjust the guide rail width of the transmission system of the SMT pick and place machine. The guide rail width should be greater than the pcb width by 1mm, and at the same time ensure that the pcb slides freely on the guide rail;
11. Set up the pcb positioning device at the same time.
Second,precautions for safe use of SMT pick and place machine.
1. When the machine is in operation, it is not allowed to extend the head, hands, and other parts into the machine.
2. When changing materials, be sure to stop the machine and open the safety door, or press the emergency switch to change materials.
3. If there is an emergency, press the emergency switch first, and then notify the equipment technicians to solve it.
Third,precautions for refueling operation of SMT pick and place machine
When changing the material of the SMT pick and place machine, it is necessary to see the spacing of the material. The standard distance between the hole and the hole on the material belt is 4mm, and the spacing of the general material is 4mm. The special material packaging depends on how many holes there are between the materials to determine the distance between the materials.
Forth,matters needing attention before and after loading when changing the line of SMT pick and place machine.
1. Before feeding, clean the Feeder Table and check whether there are components or other sundries under the Feeder that cause the Feeder to deviate. If there are, remove them.
2. After loading the material, check whether the material is in place, and use the moving lens to check whether the feeder is out of position.
