1, smt mounter is a SMT mounting device specially designed and customized for chip processing industry. Various sensors with excellent functions on SMT mounter can transmit functional program data to computer for processing during operation, which ensures the stability and reliability of the whole mounting process. Some products do not require high precision of mounter, but require high speed, so it is necessary to maintain smt mounter on schedule according to scientific methods and technical specifications.
2. The speed of 2.smt mounter must be fast, and the minimum mounting speed can reach more than 18000 points per hour.
3. LED mounter in 3.smt mounter can mount PCB with minimum length of 1200mm.
4. Easy to learn and humanized operation method can reduce the operation time of mounter. If the wrong operation mode is used in the machining process, the efficiency and quality of the product will be reduced. The mounter production line is divided into full-automatic and semi-automatic mounter. Semi-automatic needs two people, and fully automatic only needs one person to operate and manage. Thrifty human resources.
5. Multifunctional SMT mounter can mount various components: various resistors, capacitors, IC, BGA, QFP, CFP,&; μBGA, can be mounted. Generally speaking, in the production line of mounting technology, high-speed mounter and multifunctional mounter are used together.
6.SMT high-speed mounter can mount 0402-40mmIC components, and the best mounting speed can reach 15000CPH.
Adjustment method of position and direction of parts of arch mounter;
1. Adjust the position by mechanical centering and the direction by rotating the suction nozzle. The accuracy that this method can achieve is limited, so it will not be used in future models.
2. Laser identification, X/Y coordinate system adjustment position and nozzle rotation adjustment direction. This method can realize the recognition in flight, but it can't be used in BGA.
3. Camera identification, position adjustment of X/Y coordinate system and rotation direction adjustment of suction nozzle. Generally, the camera is fixed, and the chip head flies over the camera for imaging recognition, which takes a little longer than laser recognition, but it can recognize any component. There is also a camera recognition system that realizes recognition in flight, and there are other sacrifices in mechanical structure.
In this form, the speed is limited because the chip head moves back and forth for a long distance. At present, generally, multiple vacuum suction nozzles are used to take materials at the same time (at most ten) and a double-beam system is used to improve the speed, that is, while the patch head on one beam takes materials, the speed of the patch head on the other beam is almost twice that of the single-beam system. However, in practical application, it is difficult to achieve the condition of taking materials at the same time, and different vacuum nozzles need to be replaced for different types of components, so there is a time delay in replacing the nozzles. This machine tool has the advantages of simple system structure and high precision, and is suitable for parts of various sizes and shapes, even special-shaped parts. Feeders are in the form of belts, tubes and trays. Suitable for small and medium-sized batch production, but also multi-machine combination batch production.
