Description

Roll tape automatic cutting device {APPARATUS FOR AUTOMATICALLY CUTTING ROLL TAPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll (reel) tape automatic cutting device, and in particular, a roll tape that automatically cuts to collect a roll tape or a reel tape (hereinafter referred to as "roll tape") generated when supplying parts of a chip mount. It relates to a cutting device.

Chip mount is a device for mounting on a printed board by clamping large and small types of electronic components supplied through roll tape. The roll tape used at this time is a tape made of materials such as paper and synthetic resin, and is manufactured in various kinds of thicknesses and widths and gaps between insertion grooves according to the size and shape of the electronic component to be clamped. Depending on the spacing of the insertion groove, the speed of discharging to the outside after supplying parts varies.

These roll tapes are extended to a length of about 40 ~ 80m. If you keep the empty roll tape discharged after supplying electronic parts, it will not only hinder the working environment but also provide space for storing them separately. It reaches the limit.

Therefore, there is a need for steel balls to improve the working environment by frequently cutting the roll tape discharged to the outside after being used in the chip mount.

As an example of the effort, a roll tape automatic cutting device is disclosed in Korean Registered Credit Model Publication No. 20-0231404. The registered credit model registration No. 20-0231404 is a pinion gear that rotates by engagement with a rack gear parallel to the guide rod on a chain rotated by a reduction motor and a movable body reciprocating from side to side along a guide rod parallel to the chain. And, the pinion gear is guided to the guide rod of the movable body is connected to the variable blade and the operating rod to operate back and forth, and the front of the variable blade to face the fixed blade fixed to the movable body, cutting is made quickly and easily In addition, there is no fear of pulling the roll tape during cutting, thereby preventing malfunction of the chip mount, thereby improving productivity.

Such a roll tape automatic cutting device is installed so that the reduction motor is perpendicular to the longitudinal direction of the main body, the fixed blade and the variable blade is also horizontally installed in a direction perpendicular to the main body has a wide width before and after. Therefore, when the chip mount is installed adjacent to other electronic devices on the line, when the feeder station having a large projecting width from the chip mount is used as a part supply means, the chip mount can be simply and easily installed using a large space portion under the feeder station. However, when a docking cart having a narrow chip mount protrusion width is provided as a part supplying means, a space under the docking cart is narrow, which causes difficulty in moving.

In addition, the variable blade is operated by a rack and pinion gear with a high unit cost, which requires a lot of manufacturing cost, and the reciprocating motion of the moving body is not flexible, which causes severe noise during operation, and is discharged when there is a difference in shape or height of the chip mount. There was a problem that the roll tape was stretched for a long time and roll tape feeding or cutting was not performed properly.

Korean Patent Laid-Open Publication No. 2001-0090089 is an example of an automatic roll tape cutting device for solving this problem. The roll tape automatic cutting device of Korean Patent Laid-Open Publication No. 2001-0090089 includes a chain rotated by a reduction motor and a moving body reciprocated by forward rotation of the reduction motor by a limit switch attached to both sides. The fixed blade is fixedly installed so as to partially overlap with the working blade rotating together with the driving sprocket combined with the chain and the bottom of the working blade so that cutting is made between the fixed blade by the rotation of the working blade when the moving object is moved. Disclosed is a technique.

However, in the conventional roll tape automatic cutting device of the Republic of Korea Patent Publication No. 2001-0090089 as described above, the cutting tapes are not cut between the stationary blade and the rotary blade, and the sliding phenomenon occurs. It may slip and not cut. The roll tape should not be subjected to any kind of force before cutting. Depending on the material, shape and size of the roll tape to be cut, the force to be pulled on the tape prior to cutting due to tearing or pinching will occur. There is a problem that noise occurs because it moves in conjunction with the rotation of the chain. In addition, such a device is a paper tape is laminated because the blade is worn a lot of frequent replacement, there is a problem that a lot of industrial waste occurs because the recycling tape and the waste tape is not collected separately.
