Concept of the SMT Telescopic Angle Machine

The SMT Telescopic Angle Machine is an automated device employed in SMT production lines to achieve 90-degree directional conversion of PCB boards. Its core function involves altering the PCB conveying direction through telescopic tracks, rotation, or lifting mechanisms. The following is a comprehensive overview:

I. Structural Composition and Working Principle

‌Structural Principle‌: Utilises an adjustable-width track carriage to achieve precise alignment between two devices through track extension/retraction, elevation, and rotation.

‌Operational Sequence‌:

Receive PCB → Positioning complete → Track retracts → 90-degree rotation → Track extends → PCB discharge complete → Cycle to standby.

Select models support instant switching between straight-through and angled modes via the human-machine interface.

II. Technical Parameters and Performance

‌Dimensions and Compatibility‌:

Common external dimensions range from 550×550×950mm to 780×780×1200mm.

Supports PCB board sizes from 50×50mm to 450×460mm; custom non-standard specifications available for select models.

Power System:

Stepper motor-driven rotation with high-precision ball screws and linear bearings ensuring repeatable positioning accuracy.

Conveying speed: 1–12 m/min; cycle time: approximately 10–15 seconds.

Control and Safety:

PLC control system featuring SMEMA standard signal interfaces for automated integration.

Safety enhanced by photoelectric protection sensors and enclosed rotating design.

III. Application Scenarios and Advantages of Telescopic Angle Machines

‌Suitable Scenarios‌: SMT dual-function production lines, L/U-shaped lines for PCB flow direction adjustment, diversion, or convergence.

‌Core Advantages‌:

Labour savings and reduced production costs.

High-stability frame (cold-rolled steel plate + powder coating process) and electromagnetic interference resistance.
