Description

Paper removal device {Paper removal device}

The present invention relates to a separator removing device, and more particularly, by having a suction roller rotating in the same direction between a plurality of transfer rollers for transferring a plurality of PCB products disposed on the upper part of the separator, when the product detection sensor is operated The suction roller sucks in the separator and easily separates and discharges the separator from the PCB product to the lower part of the separator, thereby automating the removal of the separator. It relates to an interleaf removal device for stably conveying the PCB product through the interleaving discharge space to the rear conveying roller by pressing and raising the PCB product, which is easily bent by the pressure roller.

In general, PCB (Printed Circuit Board) is a part widely used in electrical and electronic products and is supplied sequentially through a supply device. is plugged in

In order to supply the PCB product through the supply device, the separator and the PCB product must be separated and supplied separately.

The PCB product, which is the object of the present invention, is not adsorbed by intake air because a plurality of through holes having various sizes are irregularly formed throughout the product in a state before semiconductor chips or electrical components are combined.

Accordingly, the suction plate is configured to be able to move up and down and move left and right on the bottom of the two separate transfer holes on the long moving rail, and while the sucker selectively repeats the lifting and moving left and right, the slipper is placed on a loading plate configured on one side for reuse. The work is done by placing the PCB on the transfer conveyor and supplying it.

However, since the PCB supply device of the above configuration requires a large installation space, there is a disadvantage in that a lot of restrictions follow the installation of the device for supplying the PCB.

As another example, one suction plate is configured to be movable up and down and left and right on the rail, and while the sucker goes up and down, it sequentially adsorbs the interleaf and PCB, then moves to one side and puts it on the conveying conveyor, and on the conveying conveyor When the separator and the PCB are placed sequentially, the transfer conveyor rotates in reverse to move in the opposite direction to the PCB supply direction, drop and collect in a separate collection location, and the PCB rotates in the forward direction to be fed to the work line.

In the case of the device of the above configuration, the installation place does not require a large space compared to the above device in which the two suction plates move left and right, but the interleaf placed on the transfer conveyor rotates backwards and falls to the collection site and collects for recycling. There are disadvantages such as requiring a separate worker to collect and sorting slip sheets collected by falling again, and there are also disadvantages in that they cannot be recycled and must be discarded due to pollution caused by falling to the floor.

In particular, since one suction plate moves up and down while moving left and right on the rail, the PCB supply is not smooth and workability is not good because it is a configuration in which the separator and the PCB are placed and supplied one by one on the transfer conveyor.

In order to solve this problem, Utility Model Registration No. 20-0244501 separate supply and loading device for PCB and interleaving paper consists of a horizontal transfer port having a suction pad on the rail so that it can be moved left and right, and a loading part and a supply unit are located below the horizontal transfer port. A vertical transfer port equipped with a suction pad is installed at the top of the loading unit to alternately load the PCB and an interleaf into the loading unit, and then the PCB is adsorbed using the suction pad, and then the horizontal transfer port is transported along the rail. Let the PCB be supplied on the feeding roller of the supply part, and with the horizontal conveying port moved to one side, the vertical conveying port is lowered to adsorb and raise the interleaving paper. The pallet constituted in was placed directly below the vertical transfer port, and in this state, the movement of sequentially loading the interleaved paper adsorbed on the vertical transfer port on the upper side of the pallet was repeated.

However, there are many types of PCBs, and not only are they very thin and flexible, but also there is a problem in that it is difficult to remove the interlayer from the PCB because it is difficult to adsorb if there is a through hole.
