Description

Tape Feeder for Chip Mounter

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape feeder for a component mounter for pulling out electronic components such as chips, preferably semiconductor chips, one by one from a carrier tape in which a plurality of electronic components are separately stored in a line and sealed by a cover vinyl, and supplying them to the mounter. More specifically, by cutting the cover vinyl using a cutting punch and simultaneously discharging the cut wick cover vinyl and the base tape, the component mounter is designed to maximize device reliability, simplify component parts, and reduce overall volume. A tape feeder.

In general, a component mounter (chip mounter) picks up and picks up an electronic component supplied from a feeder by vacuum suction to a nozzle of a head that picks and places a pick and places it on a substrate.

With the development of the electronics industry, printed circuit board mounting technology is also developing day by day. The conventional printed circuit board surface mounting technology is completed by soldering after inserting a component into a through hole of a printed circuit board.

With the recent development of electronic technology, electronic components are becoming more compact and require high-density component mounting.In addition, the component mounting technology of printed circuit boards is not limited to the conventional through-hole method. The Surface Mounted Technology (SMT) method of mounting has become mainstream.

The conventional SMT surface mounter is installed to be spaced apart from the tape winding part and the tape winding part interlocked by a SMD (Surface Mounted Device) head and is coated on the tape transfer part and the upper surface of the tape to transfer the tape on which the parts are mounted. It comprises a vinyl recovery unit for recovering the vinyl to prevent separation of the transmission unit and a transmission unit for interlocking the tape winding unit and the vinyl recovery unit.

Here, the tape winding part has a structure in which a drive latch rotated in one direction by a push rod and a ratchet pole connected thereto are mounted on a tape feeder plate, and a tape on which a component is mounted is wound. It has a winding shaft.

The vinyl recovery part includes a vinyl winding reel having a winding gear rotatably installed on the bracket and a fixing lever fixed to one side of the vinyl winding reel, a rotating lever rotatably installed on the other side of the fixing lever, and a pinion installed on one side of the rotating lever. It consists of.

The transmission part is installed in the intermediate portion is connected to the transmission plate, one side of the link lever is connected to interlock with the lower end of the push rod of the tape winding portion and one end is connected to the end of the link lever by a hinge, the other end of the rotation of the vinyl recovery portion It is composed of a link lever that is installed to be linked to the lower end of the lever.

The feeder has been disclosed in various types such as a tape feeder, a chip feeder, a tray feeder, etc., but a tape feeder capable of supplying chips at high speed and in large quantities is widely used. Carrier tape is applied to such a tape feeder.

The carrier tape has two types of tape and embossing type, and the carrier tape is difficult to be pulled out one by one due to the extremely small size of electronic components, and is not easy to handle due to the possibility of loss due to the minute size. .

In particular, as shown in FIG. 1, the above-described carrier tape 2 includes electronic components such as a semiconductor chip 8 in a storage space 6 formed at a predetermined interval on the base tape 4 of a paper material. The tape is treated with a cover vinyl 10, and is distributed in a form in which a transfer hole 12 spaced apart by a predetermined interval in the longitudinal direction of the tape is formed at one side.

The carrier tape is mainly used in a shape in which the storage space between the electronic components is 2 mm to several intervals.

The carrier tape locks the transfer hole by a tape feeder mounted in the component mounter, moves by a predetermined pitch, and the base tape and the cover vinyl are separated in stages, and the electronic components in the exposed storage space are sucked out by the suction nozzle. .

In the conventional tape feeder having this structure, when the carrier tape is mounted on the tape feeder, the operator must separate the base tape and the vinyl directly, and the carrier tape is stored in the storage space in the process of connecting the carrier tape to the tape feeder due to the operator's carelessness. There is a problem that frequently occurs when the electronic component is lost.

In addition, the base tape is discharged to the front part, and the cover vinyl is separately discharged to the rear part, so that the cover vinyl discharge part may be entangled, and the parts may be lost, and the pitch may be changed due to the pulling of the cover vinyl. Accurate pick-up is difficult and there is a problem that must be reset.

In order to overcome this problem, the applicant of the present invention in the Republic of Korea Patent Application No. 2007-0053268 the gate block provided in the tape feeder for the component mounter, the gate block, the guide block and the gate cover is installed on one side of the gate cover and the gate cover Consists of a cutting punch connected to one side of the upper side, the cutting punch with the cover vinyl and the base tape of the carrier tape together to simplify the device, reducing the waste of electronic components during the initial insertion of the carrier tape, cover vinyl Since the discharge part is not needed, the pickup error of the electronic parts caused by the pulling of the cover vinyl is minimized.

However, the above-described technique is configured such that the cutting punch for separating the cover vinyl of the carrier tape cuts only one side corresponding to the longitudinal direction of the cover vinyl in which the semiconductor chip is housed, that is, the other side opposite to the conveying hole.

The present invention provides a cover vinyl and a base tape by cutting and separating a central portion of a cross section with respect to the longitudinal direction of the cover vinyl in separating the cover vinyl of the carrier tape containing the electronic component provided in the tape feeder for the component mounter from the carrier tape. There is a technical problem to provide a tape feeder which improves workability by opening the gate member to the second half of the tape feeder without simultaneously discharging it to the front part and requiring a cover vinyl discharge part.

In order to solve the above problems, the gate member constituting the tape feeder for a component mounter according to the present invention comprises a gate cover; A cutting punch connected to one side of the gate cover in a direction in which the carrier tape is supplied, the cutting punch being provided to cut the center of the cover vinyl of the carrier tape; And a guide member inserted into the lower end of the cover vinyl of the carrier tape at the lower end of the cutting punch to separate the cover vinyl and the base tape.

The present invention simplifies the apparatus by discharging the cover vinyl and the base tape together using a cutting punch, reducing the waste of the semiconductor chip during the initial insertion of the carrier tape, and eliminating the need for the cover vinyl discharge portion. It is possible to minimize the error of semiconductor chip pick-up generated.

The present invention provides a tape conveying member for conveying and supplying a carrier tape at a predetermined pitch to the front and rear of the body mounted on the component mounter; A gate member installed to mount and transport the carrier tape; In the tape feeder for a component mounter made of a drive member for providing a driving force for conveying the carrier tape,
