Abstract

PURPOSE:To obtain a taped component feeding device holding always a normal attitude by a method wherein an edge part is formed into the form of a projecting curve and curve parts or linear parts slanted to the edge part for peeling an adhesion part are respectiely provided on both sides of each housing chamber. CONSTITUTION:An edge part 4b of a press plate 4 is formed into roughly a semicircle and a peeling part 4c, which contacts an adhesion part 3a of a cover tape 3, is brought into contact to the tape 3 at an angle shown by an angle dimension line theta. Moreover, a gap 5 is made narrower than the width of electronic components 2 due to the formation of the semicircular edge part 4b. As the tape 3 is continuously stripped off its adhesion part 3a by the peeling part 4c which comes into contact with the tape 3 at the angle theta of inclination, the component 2 in each housing chamber 1a is not made to move and is fed to a prescribed component feeding position while holding a normal attitude. The edge part 4b is formed into roughly a semicircle, but if the peeling part 4c has an inclination to the adhesion part 3a, a projected curve may be used and the peeling part 4c may be constituted of a straight line.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a taping component supply device that supplies components arranged and stored at a constant pitch within a tape one by one at a predetermined component supply position. be.

(Prior Art) A conventional taped component supply device peels off the cover tape with a cover tape peeling device disposed in front of a predetermined component supply position, and supplies components one by one at the predetermined component supply position.

Regarding the above-mentioned conventional cover tape peeling device, Fig. 2 (
This will be explained using a) and (b). FIGS. 2(a) and 2(b) are a plan view and a side sectional view of a conventional cover tape peeling device.

A carrier tape 1 used in a component supply device stores electronic components 2 one by one in a uniform direction in storage chambers 1a formed at a constant pitch on one side to prevent them from moving or falling off. The cover tape 3 is attached to the adhesive parts 3a on both sides.
It is glued with.

The cover tape peeling device is disposed between an intermittent drive device (not shown) placed in the front and a carrier tape supply reel (not shown) placed in the rear, and has a straight line at the tip for peeling off the cover tape 3. It is composed of a presser plate 4 having an edge portion 4a formed therein, and a cover plate 6 that protects the carrier tape l on which the electronic component 2 is exposed, with a gap 5 through which the cover tape 3 passes.

(Problem to be Solved by the Invention) However, with the above configuration, as the size of electronic components has become smaller as in recent years, it is difficult to remove the adhesive portion 3a of the cover tape 3 from the carrier tape 1 all at once. There was a problem in that the electronic components 2 danced due to the generated vibrations of the carrier tape 1 and also stood up due to the static electricity possessed by the cover tape 3, making it impossible to supply them in a normal position.1 The present invention solves the above problems. The purpose of the present invention is to provide a parts feeding device that always maintains a normal posture.

(Means for Solving the Problems) In order to solve the above problems, the present invention forms an edge part in a protruding curved shape, and includes an inclined curved part or a straight part on the edge part from which the adhesive parts on both sides of the storage chamber are peeled off. It shall be established.

Further, the edge portion is semicircular.

(for production) With the above configuration, the cover tape 3 can be peeled off.

Since it is continuous, it does not cause the carrier tape 1 to vibrate, and the effect will be even greater if it is peeled off at a uniform speed on a straight line with slopes on both sides of the storage chamber 1a. Moreover, since the gap with the cover plate 6 becomes smaller, it is possible to suppress the movement of the electronic component 2.

(Example) An embodiment of the present invention will be described with reference to FIG.

FIGS. 1(a) and 1(b) are a plan view and a side sectional view of a cover tape peeling device of a taping parts supply device according to the present invention, and this embodiment is different from the conventional example shown in FIG. The points are the point where the edge portion 4b of the presser plate 4 is approximately semicircular and the peeling portion 4C that contacts the adhesive portion 3a of the cover tape 3 is brought into contact at an angle shown by the angular dimension line θ in the figure, and the point where the edge portion 4b of the presser plate 4 is approximately semicircular. This is because the gap 5 is made narrower than the width of the electronic component 2 by forming the edge portion 4b. Since the rest is the same as the conventional example, the same components are given the same reference numerals and their explanations will be omitted.

The operation of the cover tape peeling device configured as described above will be explained.

Since the adhesive part 3a of the cover tape 3 is continuously peeled off by the peeling part 4c that contacts at the inclination angle θ, the electronic components 2 in the storage chamber la do not dance and maintain their normal posture.
It is sent to a predetermined parts supply position.

In this embodiment, the edge portion 4b is approximately semicircular, but as long as the peeling portion 4c has an inclination with the adhesive portion 3a, it may be a convex curve, or the peeling portion 4c may be formed of a straight line. Needless to say, it's a good thing.

(Effects of the Invention) As explained above, according to the present invention, when the cover tape is peeled off from the carrier tape, the electronic components stored in the storage chamber do not dance and are stably attached to the component mounting device in a normal posture. It is possible to improve the component suction rate and reliability of the single component mounting device.
