Apparatus and method for replacement of defective parts of pcb panel

Abstract

An apparatus for replacing a defective PCB unit formed on a PCB panel includes a location correcting table on which a nondefective PCB unit for replacing the defective PCB unit is disposed, a panel seating table, on which a PCB panel where the defective PCB unit is removed is disposed, a seating table support on which the panel seating table is detachable installed by a fastener, a location correcting driver for driving the location correcting table relative to the panel seating table to correct location of the nondefective PCB unit with respect to the PCB panel, a vision camera for reading location of specific points on the nondefective PCB unit and the PCB panel respectively disposed on the location correcting table and the panel seating table, a reading location varying driver for sequentially moving the specific points read by the vision camera below the vision camera, and a controller for controlling the location correcting driver and the reading location varying driver, receiving operation results of the vision camera, the location correcting driver and the reading location varying driver, and controlling the location correcting driver by calculating location correcting data based on the operation results.

Description

technical field [0001] The present invention relates to an apparatus and method for replacing defective printed circuit board (PCB) units formed on a PCB, and more particularly, to replacing a defective printed circuit board (PCB) unit by replacing it with a non-defective PCB unit when there is at least one defective PCB unit The defective PCB unit is an apparatus and method for rectifying a PCB board having a plurality of PCB units. Background technique [0002] Generally, PCB units are manufactured one by one. However, in recent years, in order to improve productivity and yield during the automatic part mounting process, multiple PCB units having the same pattern as each other are printed on a single board and separated as a single unit after the part mounting process. [0003] This kind of board on which multiple PCBs are printed is called an array PCB board or simply a PCB board. According to the number of PCB units arranged in an array on the board, the PCB board is c...

AI Technical Summary

Problems solved by technology

However, even if the fixing pin and the fixing pin insertion hole are precisely machined, there may be some errors in the process of embedding the fixing pin into the fixing pin insertion hole

That is, it is difficult to manufacture the precise fixtures required for high-density PCB boards

In addition, the fixture board is easily deformed, and the position of the pin is easy to move, resulting in defects of the PCB board

When the fixture is deformed, the entire fixture body needs to be replaced, increasing manufacturing costs
