Incidentally, on the top and side surfaces of the tape guide support frame 25, an engaging portion receptacle as shown in FIGS. 1 and 3 is formed with seven hanging pieces.

As shown in FIG. 3, the tape guide 2 has an opening-shaped cross section, and is formed to guide a tape T on which a large number of electronic components n as shown in FIG. 5 are attached. Also, at the tip of the tape guide 2, there is an extending piece 2b on the same surface as the bottom plate part 2a.
is formed, but this extending piece 2b is connected to the tape guide 2.
When set to the lower movement position, it is located inside the feed wheel 13, which will be described later. A tape presser 4 is attached to the upper edge of one side wall portion 2c of the tape guide 2 via a hinge pin 5 arranged in the elongated direction so as to be openable and closable.

As shown in FIG. 3, the tape pusher 4 has a mouth-shaped cross section, and is pivoted to the tape guide 2 at its right edge. As shown in FIGS. 1 and 2, the tape presser 4 allows the majority of the tape guide 2 except for the rear portion to be closed, and has a tip portion 26 extending forward from the tape guide 2. . A pair of left and right notches 26a are formed in this tip portion 26, into which a feed wheel 13 (described later) is loosely inserted. Further, at the rear end of the tape presser 4, when the tape presser 4 is closed and the tape guide 2 is set to the downward movement position, a main body 1 is attached as shown in FIG.
The engaging portion receiver has an engaging portion 6 that is elastically engaged with the piece 7 and is formed to hang down.

A pair of left and right levers 8 supported by the bottom plate 2a of the tape guide 2 via a shaft pin 9 are disposed below the tip of the tape guide 2.

This lever 8 is pivotally supported at the center by a shaft pin 9, and the tip portion 8a bent upward is located on the side of the extension piece 2b, and when the tape guide 2 is in the downward movement position, As shown in the drawings and FIG. 5, the upper end of the tip portion 8a projects slightly above the upper surface of the extension piece 2b. A triangular positioning recess 8 for engaging the lead wire (tape engagement part) m of the electronic component n is provided on the upper side of the tip 8a.
b is formed. A compression spring 27 is interposed between the rear end portion 8C of the lever 8 and the bottom plate portion 2a of the tape guide 2, and biases the lever 8 clockwise in the figure. As shown in FIGS. 2 and 6, when the tape guide 2 is in the downward movement position, the lever 8 is accommodated in the recess 21 formed on the upper surface 24a of the tip 24 of the main body 1. At the same time, the rear end portion 8C of the lever 8 comes into contact with the surface 22 of the step portion formed at the rear portion of the concave portion 21, and the lever 8 rotates counterclockwise in the figure. The extension piece 2b is retracted below the upper surface, and the engagement with the lead wire m of the electronic component n is released. A tape position regulating device that uses such a pair of left and right levers 8 to regulate the position of the tape 40 when the tape guide 2 is in the downward movement position, and releases the regulation when the tape guide 2 is in the downward movement position. 10 are configured.

A tape feeding mechanism 20 is provided at the tip end 24 of the main body 1 . This tape feeding mechanism 20 includes a pair of left and right feeding wheels 13 and a ratchet wheel 2, which are fixed to a common shaft 11 and rotate integrally. A ratchet pawl 15 is provided at the tip of the drive lever 14 which is pivotally supported by the common shaft 11, and when the drive lever 14 is rotated counterclockwise as shown in FIG. Furthermore, when the feed wheel 13 is driven to rotate in the same direction and the drive lever 14 is rotated in the opposite direction, the ratchet pawl 15 is configured to slide on the ratchet wheel 12 and the driving force of the drive lever 14 is not transmitted. There is. A spring 16 biases the drive lever 14 clockwise and rotates the drive lever 14 back to its original position.

The reverse rotation of the ratchet wheel 12 is prevented by a reverse rotation prevention pawl 17a provided at the tip of the reverse rotation prevention lever 17. Reference numeral 19 denotes a spring for pressing the reversal prevention pawl 17a against the ratchet wheel 12. The tape feeding mechanism 20 configured as described above is driven by a rotary drive source 28 that rotates in one direction as shown in FIG. The ratchet wheel 12 is rotated in one direction by l pitch.

Next, a method of using the electronic component supply apparatus having the above configuration will be explained. As shown in FIG. 1, a tape T to which a large number of electronic components n having lead wires m at both ends are attached in parallel is first opened when the tape presser 4 is opened and the tape guide 2 is in the downward movement position. is set in the electronic component supply device. That is, while placing the tape T on the tape guide 2,
The left and right lead wires m of the component n at the foremost position of the tape T are connected to the positioning section 8 of the lever 8 of the tape position regulating device IO.
b. Next, the tape presser 4 is closed and the tape T is lightly sandwiched between it and the tape guide 2, and the tape T is positioned. Thereafter, the tape guide 2 is rotated downward and placed on the upper surfaces 24a and 25a of the main body 1, as shown in FIGS. 2 and 6. At the same time, the engaging portion 6 is forcibly secured to the piece 7 while the left and right leads of component n are held together! m is engaged with the groove of the feed wheel 13 of the tape feed mechanism 20, and as shown in FIG. 6, the lever 8 is rotated to release the engagement between the positioning recess 8b and the lead wire m.

By driving the rotary drive source 28 in this state, the feed wheel 13 rotates intermittently in one direction, and the component n at the foremost position on the tape T is conveyed to a predetermined position. Thereafter, the tape T is sequentially conveyed and supplied to the electronic component mounting machine.

Effects of the Invention According to the electronic component supply device of the present invention, it is possible to set the tape on which components are attached to an accurate position with a simple operation.
