Printed Circuit Board Loading Device for Automatic Reversing}

The present invention relates to a printed circuit board loading device for automatic reversal, and more particularly, is installed on one side of the printed circuit board processing unit, and vacuum-adsorbs the printed circuit board processed through the printed circuit board processing unit to the loading tray automatically. It is configured to be loaded or inverted by 180 degrees, and the printed circuit board which is inverted and loaded is configured to be inserted into the printed circuit board processing unit side, so that the printed circuit board can be discharged and inserted into a single device. The present invention relates to a printed circuit board loading device for automatic reversal, which can reduce the cost and improve the working efficiency.

In general, in order to insert a circuit component on both sides of the printed circuit board, after inserting the circuit component on one side automatically, the operator who holds the printed circuit board next to the transfer machine must turn over one by one to install the components on both sides. It was.

Therefore, there is a problem that it is impossible to insert the parts on both sides unless the operator to turn over the printed circuit board directly, which leads to a decrease in productivity because the work man-hours and the working time are long.

In addition, it is known that the type of inverted by holding the tip of the printed circuit board entering from the conveyor, and the type of inverted after lifting up in the center of the printed circuit board, this type of equipment according to the size of the printed circuit board Should be at least twice the length of the printed circuit board, or the rotation area of the printed circuit board should be secured on the upper part of the device, so that the space of the device to be installed is limited.

In addition, a conveyor is installed on the upper and lower portions of the printed circuit board so that the printed circuit board is inserted between the conveyor belt or the roller, and then the entire conveyor is rotated to overturn the printed circuit board. In the case of the printed circuit board shorter than the length of the conveyor, there is a problem that the moving time increases because the printed circuit board at the front end is moved to the rear end when the printed circuit board is inverted and moved forward.

In view of this, the patent application No. 10-2007-0015961 published a printed circuit board reversal device.

Looking at the conventional printed circuit board reversal apparatus, in the printed circuit board reversing apparatus, a fixing stand disposed on both sides of the printed circuit board, a conveyor installed on each side of the fixing stand to transfer the printed circuit board, and the printed circuit board A reversing means installed on the fixing stand and a fixing means including a gripper holding the gripper and a rotating part rotating the gripper 180 degrees in a state of holding the printed circuit board, and between the fixing stand and the conveyor. It comprises a lifting means for moving the conveyor in the oblique direction of the lower sides of the printed circuit board to secure the rotation area.

Here, the elevating means includes a drive unit having a rear end inclined to the fixing stand and the action rod of the front end fixed to the conveyor, and a guide for guiding the movement of the conveyor, wherein the reversing means grips the center of the printed circuit board. The stopper further includes a stopper for fixing the position of the printed circuit board, wherein the stopper includes a stop at which the tip contacts the printed circuit board, a working shaft fixed to the rear end of the stop, and a movement of the stop at the printed circuit board. And a brace pivot means for selectively disengaging from the transfer area of the substrate.

However, the conventional general printed circuit board inverting device configured as described above is

With the gripper held on both sides of the center of the printed circuit board, the conveyor is moved diagonally toward the lower outer side of the printed circuit board to be separated from the rotation area of the printed circuit board, and then the gripper is rotated by 180 degrees. Although it is possible to minimize the rotation radius of the substrate, there is a problem that the middle portion of the printed circuit board may be bent or crushed because the middle portion of the printed circuit board is rotated without being supported when the printed circuit board is rotated.

When the printed circuit board (P) is supplied to the upper surface side by the inverting means after the clamping of the printed circuit board (P), inverted to 180 ° to be discharged to the tray (T) side;
It includes a storage unit 180 is fixed to the bottom surface of the opening formed on the right side of the housing 110 is provided to temporarily store the printed circuit board (P) supplied from the right side vacuum suction unit 160 ' ,
The inverting means 170, the left and right LM guide parts (171,171 ') are respectively installed in the longitudinal direction on the left inner side and the right inner side of the housing 110, and the left and right LM guide parts (171,171). ') Is fixed to one end and the other end is formed in a rectangular frame shape is formed in a rectangular frame shape, and fixed to one end of the inverting frame 172 is installed so that the inverting piston in one direction and the other direction to drive A reverse rotation bar 174 rotatably provided inside the inverting frame 172 by having one end fixedly connected to the inverting cylinder 173 and the inverting piston of the inverting cylinder 173. And a reverse plate part 175 spaced apart from each other on the reverse rotation bar 174 so as to be fixedly installed, and fixedly installed at both ends of the reverse plate part 175 at predetermined intervals. The right clamping cylinder Inverted to be located between the left and right clamp portions 176 and 176 'provided to be clampable at both ends of the printed circuit board P, which are operated and correspondingly seated, and the left and right clamp portions 176 and 176'. A plurality of non-contact pads 177 fixed to the plate part 175 and provided to protect the printed circuit board P when the printed circuit board P is seated and reversed, and the LM guide part 171 for the left side. One end of the reversing movement cylinder 178 and the reversing movement cylinder 178 of the reversing movement cylinder 178, which are fixed to the housing 110 and provided with a moving piston driven in one direction and the other direction by being located at one side. The other end is fixed to the inverting frame 172, and the inverting frame 172 is fixed so that the inverting frame 172 is movable in the housing 110 in the front and rear directions by driving the inverting movable cylinder. Connecting piece (179) Automatic reversing printed circuit board loading device, characterized in that consisting of. The method of claim 1,
One side of the upper portion of the housing 110 is inverted by 180 ° by the reversing means 170 to load the printed circuit board P loaded in the tray T to the printed circuit board processing part 10. The thickness of the printed circuit board P is measured by vacuum suction of the printed circuit board P loaded on the tray T to the left side, so that the measured value can be applied to the controller side. Automatic inverting printed circuit board mounting apparatus, characterized in that the measuring means 190 is further provided.
