Description

  The present invention relates to a component transport plate for storing and transporting components such as electronic components and a connecting device therefor.

  Carrier tapes, trays, stick magazines, bulk cassettes, and the like are known as component transport bodies that store and transport components such as electronic components and mechanical components. Of these, a carrier tape is often used because it can supply components efficiently (for example, Patent Document 1). In addition, in order to supply parts more efficiently, the length of the carrier tape has been increased.

However, the carrier tape has the following problems.
(I) Since the carrier tape is provided in a state of being wound around a reel, when the carrier tape wound around the reel is exhausted, it is necessary to replace the reel. Therefore, parts cannot be supplied during the replacement work.
(Ii) Since the carrier tape is a continuous and integrally formed product, if a defect such as defective molding occurs in part, the entire long carrier tape must be discarded. When the carrier tape is lengthened, the discard amount becomes enormous.
(Iii) Since the carrier tape is cut and discarded after use, it cannot be reused.
(Iv) In addition to the carrier tape, a top tape for closing the opening of the carrier tape storage portion, a reel around which the carrier tape is wound, etc. are necessary, and the number of components is large.
(V) The carrier tape wound around the reel tends to collapse during storage and transportation. The problem becomes significant when the carrier tape is elongated.
