The present invention relates to a method and system for bidirectional control of a PCB line, and more particularly, it is applied to an inspection machine, exposure machine, or circuit generator that inspects a PCB, so that both sides of a PCB can be inspected, exposed, and circuit generated at once. This made it possible to work efficiently.

In general fields such as home appliances, industrial equipment, and automobiles, which are used recently, printed circuit boards (PCBs) are designed with integrated circuits, so the patterns are complex and the thickness is as thin as a few millimeters or less, so precision is required during the manufacturing process. Oulo is careful not to be exposed to the risk of damage.

doesn't exist.

The AOI system to which the prior art is applied as described above consists in a form in which the PCB is put in one unit at a time in order to inspect whether there is an abnormality in the PCB that has undergone the manufacturing process, and is discharged after the inspection process.

However, when the PCB, which is made of a flexible thin film carrying integrated circuits, and is sensitive to handling, is manually put into and discharged from the AOI system as in the prior art, the risk of damage is significantly increased, and process efficiency is greatly improved during mass work. There is a problem with lowering.

In addition, when inserting and discharging PCBs to the AOI system, it takes a lot of time to replace the PCB before and after inspection, and additional devices and operations are required to load and discharge the inspected PCB, resulting in process continuity and productivity. There is a problem of degradation.

In the case of the prior art as described above, since only one side of the PCB is configured to perform operations such as inspection, exposure, and generation, there is no great difficulty in working in the case of single-sided PCBs. Due to the characteristics of the structure, a technology capable of controlling both sides of the PCB is required even in the PCB line.

Conventionally, when you want to control the PCB in the PCB line, especially when you want to control both sides, it is impossible to control both sides at the same time (inspector, exposure machine, or generator) at the same time. It takes the form of controlling one face in one place and controlling the other face in another place.

For this reason, since two identical equipments (a pair) are provided for each process for both-side control of the PCB, a lot of installation space is required, and the equipment cost is excessive because it requires a lot of equipment. Ultimately, it causes an increase in production cost and weakens competitiveness.

In addition, even if a PCB line is equipped with a pair of equipment such as an inspection machine, exposure machine or generator, there is no dedicated device for controlling both sides to be simultaneously worked while supplying and discharging the PCB with such equipment, so smooth operation is performed. There are a number of problems, such as making it impossible to do in reality.

Accordingly, the present invention was invented to solve the above problems, and is installed in front of equipment 101 such as an inspection machine, exposure machine or circuit generator constituting the PCB line, and the equipment 101 is a surface equipment 102 ) and the equipment for the back side (103) side by side to receive the PCB 105, then supply it to the equipment for the surface 102 and change the direction of the discharged PCB 105 again to turn the direction of the equipment for the back surface. so that the operation control is performed in the form of loading the PCB 105 discharged after the operation is performed by supplying it to the 103;

It is possible to achieve the purpose of maximizing work efficiency while minimizing the installation space by controlling both sides of the PCB at the same time so that the necessary work can be performed and it can be mechanically automated.

The present invention can be applied to a PCB line to control the PCB in both directions at once to perform various operations related to PCB manufacturing, such as PCB inspection work, exposure operation, and circuit generation operation, thereby increasing the work efficiency of the PCB line. have an effect

The present invention automates the overall control of the PCB in the PCB line to prevent damage in the process of supply and discharge, etc. in the process of controlling the PCB, thereby excluding the occurrence of defects and ensuring safety while ensuring the quality of the PCB in an excellent and uniform state has the effect of sustaining

The present invention relates to the process of supplying the PCB to the equipment in the process of controlling the PCB in the PCB line, the processing process of the intervening paper interposed between the BC and the PCB, and the interposition between the PCB and the PCB that are supplied and discharged to the equipment.
