Electronic part feeder

Abstract

An electron-unit supply arrangement can prevent the paperfibre attached on the driving belt and the covering belt when detaching the covering belt from clinging to the projecting part. Accordingly, the covering belt can be smoothly detached from the driving belt, which can avoid the adsorptive error to the electron unit. The electron-unit supply arrangement includes: driving belt which takes in the units with equal interval and forms the bonding unit on the two edges along the direction of length with predetermined interval; covering belt which bonds with the said bonding unit of the driving belt; driver element which intermittently transports the driving belt; stripping element which detaches the covering belt from the driving belt; and winding element which can coil the covering belt separated from the driving belt. In the said electron-unit supply arrangement, the said stripping element includes a marginal element which detaches the covering belt from the driving belt; and a projecting part, in which the gap between the said projecting part and the said marginal element is set along the transfer direction of the driving belt and a straight-line element with a smaller gap than the said bonding unit of the driving belt is formed on the relative margin of the said marginal element.

Description

technical field [0001] The present invention relates to an electronic component supply device capable of peeling a cover tape (cover.tape) from a carrier tape that accommodates electronic components in a storage recess. Background technique [0002] According to the electronic component supply device described in Patent Document 1, as a unit for peeling the cover tape (top tape (top tape)) from the carrier tape, the cover tape is inserted into the slit provided in the tape guide, and the pair of slit end faces constituting the slit Peel the cover tape from the carrier tape. [0003] The notched end surface is configured such that the notched end surface on the conveying direction side (downstream side in the conveying direction) of the carrier tape is formed into an arc shape with an arbitrary curvature centered on the moving track of the electronic component of the carrier tape, so that the electronic component is pressed when the electronic component is adsorbed.

Problems solved by technology

For example, when the winding force of the cover tape is strong, the breakage of the cover tape occurs, or conversely, when the winding force is weaker than the tape conveying force, the peeling cannot be performed because the cover tape enters under the tape guide. Either situation can lead to the inability to peel the cover tape from the carrier tape stably and not be able to adsorb the electronic components
