Method to increase the speed of SMT placement machine

At the SMT speed, as far as I know, the methods for roughly increasing the speed of the placement machine are mainly divided into the following types: During the production process, in view of the importance of the placement speed of the placement machine, many placement machine manufacturers are doing everything possible to improve Mounter speed

1. Structural improvement of placement machine

The use of dual tracks allows PCB placement on one track and board feed on the other track, which reduces PCB delivery time and placement head standby time.

Multi-mount head combination technology

At present, there are double-headed Hetian four-headed arched structures that are driven at both ends to prevent the cantilever beam effect and reduce the mechanical stability time.

Combined (or modular) multi-unit structure, emphasizing the mounting speed per unit area.

2. Mounting head and nozzle technology

Lightning head

Multi-nozzle structure Up to 30 nozzles on one placement head, with high stability and strong adaptability, capable of mounting from 0201 and 01005 components to 30 mm × 30 mm QFP components;

3. Motion drive and linear motor technology

Using fuzzy control technology, there are three stages of control during the movement, that is, "slow, fast, slow", which changes in an "S" shape, so that the movement becomes both "soft" and fast.

The patented linear motor with high positioning accuracy and high repeatability, high speed and high acceleration, fast and stable (up to 55ms), small working current, and high precision control.

Four, rapid detection technology

Laser and CCD application cooperation

Dual cameras-separate detection of chip components and large-size ICs, enabling fast image acquisition and conversion circuits.

5. Feeder technology

The feeding method of the intelligent feeder can shorten the time of human error when replacing components. It can change materials without stopping, double belt feeder, large feeder capacity, and some placement machines can reach the capacity of 256 8 mm feeder, which can efficiently feed in bulk.

6. Software Technology

Various forms of PCB files can directly optimize the generation of patch program files, reduce manual programming time, suitable for machine fault self-diagnosis systems and large-scale production management systems, and can intelligently operate the system.
