Electronic part supplying tape and electronic part supplying tape connecting method

Abstract

In a carrier tape for supplying electronic parts to an electronic part mounting apparatus for taking the electronic parts from a tape feeder for mounting on a circuit board, a trailing-side connecting portion having a cut portion is provided on an already On the rear side of the carrier tape mounted on the tape feeder, a front side connecting portion having a cutout portion is provided on the front side of the carrier tape to be used, and in the tape splicing operation when the reel is replaced, so The cutout portion is fitted on the cutout portion, and the adhesive tape is stuck thereon from the upper and lower surfaces thereof. Thereby, the rear side connecting portion and the front side connecting portion can be positioned in the longitudinal, width and thickness directions of the carrier tape, and can be efficiently connected without using a dedicated connecting jig.

Description

technical field [0001] The present invention relates to an electronic parts supply tape for holding electronic parts at a constant pitch on a belt-shaped member and feeding the electronic parts, and a method for connecting the electronic parts supply tape. Background technique [0002] According to a method for feeding electronic parts to a delivery head, in an electronic parts mounting apparatus, an electronic parts supply belt (hereinafter simply referred to as a "carrier belt") for holding a large number of electronic parts in on a strip member. In this method, the carrier tape is supplied in a state wound on a supply reel, and this carrier tape is drawn off from the supply reel mounted on a tape feeder (a tapefeeder), and The timing of mounting these electronic parts is synchronously fed pitch-by-pitch to thereby sequentially feed the electronic parts to the pick-up position of the delivery head. Also, when a shortage of parts occurs in the tape feeder during the insta...

Problems solved by technology

[0005] However, according to the aforementioned connecting jig (disclosed in JP-A-2000-289708), it is necessary to perform a process based on the profile of the two carrier strips or the feed holes so that the pitches of the two carrier strips and the feed holes are precisely matched and aligned. operation, and special connection fixtures are required for each carrier belt

Therefore, in order to implement the connection operation, it takes time and labor

In particular, when multiple types of carrier straps are used in combination, it inevitably increases the complexity of using the connecting jig according to the type of the corresponding carrier strap

Also, regarding work accuracy, depending on the proficiency of the operator, it may not be possible to perform correct connection under the condition of precise pitch matching or alignment, and it may cause a machine failure in which the bearing after connection cannot be normally performed. with feed operation

[0006] Also, as shown in JP-A-10-101178, according to a method of connecting carrier straps by matching embossments for storing parts to each other, these carrier straps can only Cases with special shapes are connected, and this method is not suitable for normal cases where multiple carrier straps are used

In this way, according to the carrier tape in the conventional art, there is a problem that it is difficult to efficiently carry out the tape connecting operation when the reel needs to be replaced due to shortage of parts.
