AI Technical Summary

Technical Problem

Existing SMT tooling is inefficient when handling PCB boards, and the clamping process can easily cause the PCB board to shift or components to be damaged.

Method used

A tray body was designed, which connects multiple pressure blocks via a pull strap. A sliding mechanism is used to achieve synchronous operation of the multiple pressure blocks. The combination of an airtight slider and an exhaust hole controls the slow reset clamping of the pressure blocks and uses the principle of air damping to avoid impact.

Benefits of technology

It enables the synchronous opening and closing of multiple clamping blocks, improving loading and unloading efficiency, reducing operation time, ensuring the safety and protection of PCB boards, and avoiding damage caused by excessive clamping speed.

Abstract

This invention relates to the field of SMT carrier technology, specifically to an SMT tooling fixture, comprising a tray body. The upper surface of the tray body has multiple PCB board placement slots, and a clearance slot communicating with the PCB board placement slots. A clamping assembly is disposed within the clearance slot. The clamping assembly includes a clamping block and a first spring plate. One end of the clamping block extends into the PCB board placement slot and is fixedly connected to a copper sheet. A fixing slot is formed on the clamping block. This invention features efficient synchronous operation: all clamping blocks are connected by a pull strap and uniformly controlled by a sliding mechanism, enabling the synchronous opening and closing of multiple clamping blocks (i.e., multiple workstations). The operator can release or prepare to clamp all PCB boards with a single action, greatly improving loading and unloading efficiency, reducing operation time and steps, and making it ideal for mass production.
