Problems solved by technology
[0004] Such a conventional screen printing machine applies solder paste on the printed circuit board (especially the upper surface of the mask marked with a specific pattern of openings) after installing the solder container filled with solder. Here, if the solder Insufficient solder paste in the container may result in poor coating of the solder paste on the printed circuit board
[0005] And, if the solder paste in the solder container is completely exhausted, after the work of the screen printing machine needs to be interrupted, the operator personally performs the operation of replacing the solder container, so it is necessary to invest extra work time and manpower, thereby reducing the overall The problem of process efficiency

The present invention relates to an automatic solder container supply device and method, comprising: a supply part for supplying the solder container by its own weight; a mounting part for mounting the solder container supplied from the supply part; a state of the solder container supplied and received by the unit, and apply solder paste on a printed circuit board; and a transfer unit that transfers the mounting unit back and forth between the supply unit and the operation unit, the operation unit including : a standby area where the solder container is located in a standby state before being mounted; a mounting area where a solder container moved from the standby area is mounted; The measurement value of the sensor for measuring the remaining amount of solder paste in the container is moved out of the mounted solder container.
Description
technical field [0001] The present invention relates to an automatic solder container supply device and method, and more particularly, to an automatic solder container supply device that can automatically discharge a solder-depleted container without interrupting the process and at the same time automatically supply a new container filled with solder and methods. Background technique [0002] Generally, a printed circuit board (PCB: Printed Circuit Board) built in as a main component of an electronic device such as a computer or a home appliance is coated with solder paste in a molten state in a predetermined pattern, so that many semiconductor chips or resistance chips are formed. Various forms of small electronic components can be mounted. [0003] This solder paste application process is performed by a solder paste application apparatus called a screen printer, which applies the solder paste supplied to the metal mask in which the openings of the specific pattern are for...
