BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor system for transferring a substrate, and more particularly, to a substrate fixing apparatus for a conveyor system for aligning and fixing a substrate such that the substrate to be transported is parallel to the conveyor belt.

In general, a component mounter such as a chip mounter refers to a device for mounting a component such as a semiconductor chip on a substrate such as a printed circuit board.

Such a component mounter is largely a component supply unit for supplying a component such as a semiconductor chip, a substrate supply unit for supplying a substrate such as a printed circuit board, and a component mounter for mounting components supplied by the component supply unit on a substrate supplied by the substrate supply unit. It consists of wealth.

In such a component mounting machine, many conveyor systems are applied to the board | substrate supply part which supplies a board | substrate.

Such a conveyor system is widely used because it can supply a plurality of substrates continuously by placing the substrates on a conveyor belt that rotates continuously.

On the other hand, when the conveyor system is applied to the component mounting device, there is a need for a device for stopping the substrate to be transported in the work area where the mounting operation of the component is carried out and aligning and fixing the substrate so that the stopped substrate is parallel to the conveyor belt. The reason for this is that the accuracy and reliability of the component mounting operation is maximized only by stopping the substrate to be transferred and aligning and fixing the substrate so that the stopped substrate is parallel with the conveyor belt.

Therefore, conventionally, the board | substrate conveyed using the stopper is stopped, and the board | substrate is aligned and fixed so that the board | substrate which was stopped using the board | substrate fixing apparatus may be parallel with a conveyor belt.

Hereinafter, an example of a substrate fixing apparatus of a conventional conveyor system will be described in detail.

The substrate fixing device of the conventional conveyor system is installed on one side of the conveyor belt, a '┌' shape or '┐' shape holder having a vertical surface disposed vertically with respect to the conveyor belt and a horizontal surface disposed horizontally with respect to the conveyor belt, and the conveyor A plurality of pneumatic cylinders installed on the other side of the belt and pushing a stationary substrate to the vertical surface side of the stator by applying a certain amount of physical force to one side of the stationary substrate, and installed on the lower part of the conveyor belt, And a backup table for fixing the substrate pushed to the vertical surface side of the support by pushing it up to the horizontal surface side of the holder.

Therefore, the substrate fixing apparatus of the conventional conveyor system aligns and fixes the substrate in the following manner.

That is, when the substrate to be transported is stopped in the work area where the component mounting operation is performed by the stopper, the pneumatic cylinder of the substrate fixing device is physically of a predetermined size to one side of the stopped substrate such that one side of the substrate is in contact with the vertical surface of the holder. The force is applied to push the stationary substrate to the vertical side of the holder.

Then, when the substrate is pushed to the vertical plane side of the holder, the backup table pushes up the substrate pushed to the vertical plane side of the holder to the horizontal plane side of the holder. Therefore, the substrate is aligned by the vertical surface of the holder by the action of the pneumatic cylinder and is fixed to the lower horizontal surface of the holder by the action of the backup table. Thus, the component mounting portion of the component mounter is to mount the component on the substrate thus aligned and fixed.

However, in the case of the substrate fixing apparatus of the conventional conveyor system, since the substrate is aligned by applying a certain amount of physical force to one side of the stationary substrate by the pneumatic cylinders, there is often a problem that the substrate on which the component is to be mounted is bent. This causes various problems such as component mounting error when the component is mounted on the board. In particular, recently printed circuit boards that are frequently used as substrates have become very thin, about 0.3 to 0.5 mm. Therefore, when a certain amount of physical force is applied to the side surface in the above manner, the bending of the substrate There is a problem that becomes larger.

In addition, since the substrate fixing apparatus of the conventional conveyor system uses a plurality of pneumatic cylinders to align the substrates, a plurality of additional devices are provided to control the pneumatic pressure used in the plurality of pneumatic cylinders. As a result, in the case of the conventional substrate fixing device, the error is frequently caused by various factors that can cause the operation error as well as the volume is very large and the manufacturing cost is very high.

Accordingly, the present invention has been made in view of the above problems, and the technical problem to be achieved by the present invention is to provide a substrate fixing apparatus of a conveyor system that can prevent the bending problem of the substrate in advance.

In addition, another technical problem to be achieved by the present invention is to provide a substrate fixing apparatus of a conveyor system that can simplify the configuration to minimize the occurrence of errors and minimize the volume and the manufacturing cost thereof.

The present invention for realizing such a technical problem provides a substrate fixing apparatus of the conveyor system for aligning and fixing the substrate transported by the conveyor belt. The substrate fixing device of the conveyor system is installed on one side of the conveyor belt and has a horizontal surface disposed horizontally with respect to the conveyor belt, the horizontal surface is installed on the upper side than the conveyor belt, and is installed below the conveyor belt A backup table for pushing up the substrate transported by the conveyor belt to the horizontal surface side of the holder, and coupled to the holder such that one end of the substrate pushed up by the backup table is in contact with the substrate and rotated by a predetermined angle upon contact with the substrate. It includes a rotating body for guiding the substrate in contact with the horizontal plane.

In another embodiment, the rotating body may have a curved surface having a predetermined diameter. In this case, the curved surface may contact one end of the pushed up substrate.

In another embodiment, the holder may be provided with a vertical surface which is spaced a predetermined distance from one end of the substrate to be transported by the conveyor belt to guide the transport of the substrate. In this case, the vertical plane may be connected to the horizontal plane and disposed perpendicular to the conveyor belt.

In another embodiment, the rotating body may be installed in a portion where the horizontal plane and the vertical plane of the various parts of the stator is connected.

In another embodiment, the rotating body may be coupled to the stator via a support shaft hinged to the rotating body. In this case, the support shaft may be elastically coupled to the holder to reciprocate a predetermined distance in a state coupled to the holder.
