Description

Carrier system of pallet for pcb mount line

The present invention relates to a pallet carrier system for a PCB mount line, and more particularly, the PCB is installed in front of the reflow, and is supplied with soldered and chip mounted PCBs so that the PCBs can be placed in the parts to be combined with the PCB. The present invention relates to a pallet carrier system.

The PCB mount line 10 includes a loader 20 for supplying PCBs, a screen printer 30 for applying lead solution to the PCBs, and a chip mount 40 for inserting components into the soldered PCBs as shown in FIG. 1. ) And the release mount 50 are sequentially disposed, and the reflow 60 which solidifies the component inserted into the PCB by drying the lead solution applied to the PCB on the side of the release mount 50 is provided with a reflow 60. It is installed and on its side is provided with an unloader 70 for discharging the dried PCB.

On both sides of the reflow 60, the pallet carrier system 100 for supplying the PCB to be dried in a state in which it is placed in the pallet and recycling the empty pallet discharged through the reflow 60 is installed.

In the soldered state as described above, when supplying the PCB inserted into the component to the reflow, the PCB is placed on the pallet to prevent deformation such as bending of the PCB by the weight of the inserted part and the weight of the applied lead solution, The pallet is fed to the reflow via the conveyor.

The reason for supplying the PCB in a state where it is placed in a separate pallet when supplying the reflow is as follows.

However, in recent years, since the thickness of the PCB is thin, such as 0.4 to 0.8 mm, the pin correction method cannot be taken while supplying the reflow through the conveyor, so that the pallet is further provided under the PCB so that it is easily deformed during the drying process in the reflow. It is preventing it from becoming.

Conventionally, a PCB on a conveyor is pinched by a vacuum chuck on a pallet that is lifted up by a lift.

In such a case, even if the thin PCB is precisely controlled and picked up by a vacuum chuck, the flow of the PCB can not be prevented due to vibration, and in this case, it causes the movement of the applied lead liquid.

In particular, when picking up the PCB placed on the conveyor by vacuum or adsorbing the sucker against the PCB, the deformation and flow of the PCB are generated, resulting in the flow of lead liquid and passing through the reflow. There is a problem that the inserted part is not fixed because there is no lead liquid and is cured at a completely different position.

In addition, when the lead liquid is cured while being connected to an unrelated part due to the movement of the lead liquid in the process of placing the PCB in a vacuum and placing the PCB on the pallet, various problems may occur such as a malfunction may occur when the PCB is mounted on the actual product.

Therefore, the present invention has been invented to solve the problems as described above work by supplying a pallet for placing the PCB and improving the technology for placing the PCB in the supplied pallet to be placed in the pallet without the flow of the PCB It aims to contribute to the improvement of productivity and quality by preventing the defect of the PCB passed through the efficiency and reflow.
