Reel Tape Cutter for Surface Mounting Machines {APPARATUS FOR CUTTING REEL TAPE OF SURFACE MOUNTER}

The present invention relates to a reel tape cutter for a surface mounter, and more particularly, to a reel tape cutter for a surface mounter that can increase cutting force even with a simple configuration.

In general, a tape cutter is installed on a component mounter, and the component mounter mounts electronic components such as semiconductor chips (hereinafter referred to as 'parts') on a printed circuit board (hereinafter referred to as 'board'). to be.

A number of large and small components are supplied to such a component mounting machine to be mounted on a board. When the size of the component is relatively large, the tray supply method of loading and supplying the component on a tray is applied, and the size of the component is In the case of relatively small , there is a high risk of loss or damage during parts supply, and since parts must be supplied to a more accurate location, the tape supply method is to supply parts by storing the parts in a tape and then transferring the tape. applies.

Here, the parts supply by the tape feeding method is performed by a tape feeder. In this case, the tape feeder is provided with a rotatable tape reel on which the tape in which the components are accommodated is wound. And, by transferring the tape wound on the tape reel by a predetermined distance, the parts accommodated in the tape are supplied by a certain amount to the parts mounting machine.

After supplying the parts to the parts mounting machine, the waste tape is discharged from the tape feeder and cut by the tape cutter, and after being cut, it is stored in a pre-prepared collection box, etc. and collected.

In the case of a method of performing cutting using two blades, the tape cutter consists of a fixed blade coupled to a predetermined position, and a movable blade disposed parallel to the fixed blade and coupled to a cylinder to move toward the fixed blade. do.

Therefore, when the waste tape after supplying the parts is inserted between the fixed blade and the movable blade, the movable blade is moved toward the fixed blade to cut the waste tape.

At this time, the cutting efficiency of the waste tape is improved when the fixed blade and the movable blade are maintained at regular intervals. In addition, when maintained at regular intervals, the contact between the fixed blade and the movable blade is reduced, resulting in less wear, thereby preventing rust occurrence (a phenomenon in which rust is generated).

However, the conventional tape cutter has a problem in that it is very difficult to assemble the fixed blade and the movable blade so that a constant distance is maintained along the longitudinal direction. That is, when the distance between the fixed blade and the movable blade is too narrow, wear occurs due to the collision between the fixed blade and the movable blade, and the cutting efficiency decreases after a certain period of time. In addition, if the gap is too wide, wear due to collision does not occur, while the waste tape is not cut well and the waste tape is often caught between the fixed blade and the movable blade. .

Therefore, if the wear rate of the parts is high or the waste tape is pinched, the parts cannot be supplied, and the operation rate of the parts mounting machine is lowered, so there is a problem in that the productivity is significantly reduced.

On the other hand, in the case of the conventional rotary saw blade reciprocating and cutting the consumed reel tape, the tape is caught and dragged without being cut, so the tape length is randomly formed after cutting, and missing mass-produced products are also cut In addition to being discarded, there is a problem in that a separate wiring work for power supply to the conventional reel tape cutting device as described above is required, thereby complicating the installation.

The frame 100 may be coupled during the process line of the surface mounter. Although the slit 100a is shown to be oriented in the horizontal direction with respect to the ground in the drawing, the slit 100a is separated according to the discharge direction of the reel tape for disposal. Of course, it may be installed to face an upward direction or a horizontal direction.

The movable blade 110 is slid along the guide groove 100b of the frame 100 to guide linear movement and may be formed in the movable block 101 to be moved.

The fixed blade 120 is formed on one surface of the frame 100, and is spaced apart from the movable blade 110 so that a slit 100a is formed, so that a reel tape (not shown) can pass through the slit 100a in the longitudinal direction It may be spaced apart parallel to the movable blade 110 along the.

Here, one end of the first driving device 131 and the second driving device 132 is fixed inside the frame 100 , respectively, and the other ends of the first driving device 131 and the second driving device 132 are movable. It may be fixed to both ends along the longitudinal direction of the blade 110, respectively.

The first driving device 131 and the second driving device 132 each have a first plunger 131a and a second plunger 132a that are formed to protrude toward the movable blade 110 and are retractable so that the first plunger 131a is formed. and the second plunger 132a may be drawn out or retracted from the first driving device 131 and the second driving device 132 .
