In view of the importance of placement speed, manufacturers are doing everything possible to increase the speed of the placement machine. The methods currently used to increase the speed of the placement machine are mainly as follows.

  • Structure improvement of placement machine

Choose dual tracks to complete PCB placement on one track, and send the board on the other track, reducing PCB delivery time and placement

Standby time of loading head;

Multiple placement head combination skills, now there are double heads and 4 heads, 6 heads, 8 number one structure;

The arch structure adopts both ends to be driven together to avoid the effect of the cantilever beam and reduce the mechanical stability time;

Combined (or modular) multi-unit structure, focusing on mounting speed per unit area.

  • Mounting head and nozzle skills

Lightning placement head;

Multi-nozzle structure—up to 30 nozzles on one placement head

High reliability, high adaptability nozzle, can mount components from 0201 and 01005 to 30mm×30 mm QFP yuan

Pieces

Quickly change the nozzle.

  • Motion drive and linear motor skills

Using vague control skills, the movement process is divided into 3 stages of control, namely "slow-fast-slow", showing "s" change, from

The movement becomes both "soft" and fast;

The x-axis operation adopts a double servo motor drive system with a fully synchronized control loop to speed up the movement speed

Select high positioning accuracy and high repeat accuracy, with high speed and high acceleration, fast and stable (up to 55ms),

Patented linear motor with low working current and high precision control.

(4) Quick detection skills

Laser and CCD application cooperation;

Dual cameras-chip components and large-scale IC are detected separately

Fast image acquisition and conversion circuit

Advanced image processing and calculation software.

(5) Feeder skills

The feeding method of the intelligent feeder shortens the replacement time of components and manual errors;

Non-stop refueling

Double belt feeder;

Large-capacity feeder, some placement machines can reach 256 8mm feeder capacity

Replaceable trolley;

For devices with a lot of materials, try to use braid packaging

Efficient bulk feeding.

(6) Optimize the placement program

Optimization criteria:

The number of nozzle changes is less;

Short journey of picking up and patching

Multi-head placement machines should also consider picking up more pieces together each time

(7) Operate the machine in accordance with the safety operating procedures and improve the maintenance level of the equipment

(8) Software skills

Various forms of PCB files are directly optimized to generate patch program files, reducing manual programming time

Use offline programming for multiple varieties and small batches;

Machine fault self-diagnosis system and mass production induction system

Intelligent operation system.
