A small placement machine for special-shaped pcb boards

Abstract

The invention discloses a small-size surface-mounting machine for an irregularly-shaped PCB. The small-size surface-mounting machine comprises a working platform, wherein a fixed device is arranged ata middle part of the working platform, a surface-mounting device is arranged on the fixed device, a feeding device is arranged at one side of the fixed device, the fixed device comprises a bottom plate, a plurality of fixed seat groups are arranged on the bottom plate, each fixed seat group comprises a fixed shaft, a rotation arm is rotatably connected to the fixed shaft and comprises a rotationcylinder, an arm body is arranged at one side of an outer wall of the rotation cylinder, a wiring sliding groove and a seat body sliding groove are respectively formed in two sides of the arm body, afixed seat is arranged on the seat body sliding groove, a guide plate is arranged at an inner side of the fixed seat and is matched with the seat body sliding groove, electromagnetic locks are arranged at two ends of the fixed seat, and an installation hole is formed in the top of the fixe seat. The small-size surface-mounting machine has the characteristics of high applicability, good stability and low production cost.

Description

technical field [0001] The invention relates to a small placement machine, in particular to a small placement machine for special-shaped PCB boards. Background technique [0002] The placement machine is a device that accurately places surface mount components on the PCB pad by moving the placement head. Compared with the large placement machine, the small placement machine has low production cost, small size, and energy consumption. As an independent processing machine, it is generally placed on the desktop in the office for use due to its low profile. The current small placement machines are limited by cost and volume, and most of them use mechanical mounting structures to fix the PCB board. By distributing a number of mounting screw holes on the mounting surface, the mounting base is fixed on the corresponding position according to the shape of the PCB board. Mounting hole for installation. However, this installation method not only has installation dead angles, but als...

AI Technical Summary

Problems solved by technology

However, this installation method not only has installation dead angles, but also causes the installation position of the installation seat to not completely cover the entire installation surface, which makes it difficult to install some special-shaped PCB boards and has poor applicability; and the installation seat still has force after it is fixed. The possibility of deviation causes a slight displacement of the PCB board during placement, which affects the placement quality of the small placement machine to the PCB board

In addition, conventional SMD strips are generally conveyed by stepping motors, resulting in increased equipment costs and processing costs

Therefore, the existing small placement machines have the problems of low applicability, poor stability and high production cost
