Vinyl Collecting Apparatus of a Tape Feeder for Surface Mounting Device

The present invention relates to a vinyl recovery apparatus for a surface feeder tape feeder, and more particularly, in a surface mounter for automatically mounting electronic components on a printed circuit board, the tape feeder peels off the vinyl covered on the upper surface while transferring the tape by 1 pitch. The present invention relates to a vinyl recovery apparatus for a surface feeder tape feeder configured to easily recover the vinyl of the tape when the picker of the head picks up an electronic component embedded in the recess of the tape.

In general, the surface mounter is a surface mount assembly apparatus for mounting electronic components on a printed circuit board. The surface mounter receives various electronic components from a component supplier and transfers them to the mounting position of the printed circuit board. As an apparatus, the configuration is largely a tape feeder for supplying electronic components, an XY gantry for determining a working position, a conveyor unit for conveying a printed circuit board for working, and an electronic component from the tape feeder in order to pick up the printed circuit board. It is comprised by the head part etc. which are mounted.

The tape feeder is inserted into the recess of the tape and transfers the tape covered with vinyl by one pitch with the vinyl peeled off so that the pickers can sequentially pick up the electronic parts in the recess. As shown in FIG. 1, a driving wheel 20 is installed at a predetermined portion of the frame 10, and the driving wheel 20 is configured to transfer the tape 60. In addition, a cover 30 is installed at an upper end of the frame 10, and the cover 30 is rotatably installed at the hinge 31, and the electronic component embedded in the recessed groove 62 of the tape 60. An opening opening 32 through which the vinyl 64 covering the recess groove 62 of the tape 60 is taken out while the 63 is exposed is provided. A stepping motor (1) is provided on the right side of the frame 10. 40 is installed, and the stepping motor 40 is set to repeatedly rotate forward and backward for a predetermined time. In addition, a power switching means 70 for converting the rotational movement of the stepping motor 40 into a linear movement is installed at a predetermined portion of the right side of the frame 10. Further, the upper right side of the frame 10 is provided. The slider 50 which linearly reciprocates by the operation of the power switching means 70 operated in accordance with the driving of the stepping motor 40 is installed. One side of the slider 50 is provided with a lever 23 for rotating the ratchet wheel 26 fixed to the same axis 22 as the driving wheel 20 when the slider 50 moves forward. A first elastic member 24 is installed between the slider 50 and the lever 23 to maintain the latching state with the ratchet wheel 26 when the slider 50 is moved forward, and the lever 50 when the slider 50 is restored. (23) is reduced to the initial state. The ratchet 25 rotatably installed on the frame 10 serves to prevent the driving wheel 20 from rotating in the reverse direction by being caught by the ratchet wheel 26 when the slider 50 is restored. A second elastic member 27 is connected between the frame 10 and the ratchet wheel 26, and the second elastic member 27 serves to reduce the ratchet wheel 26 to an initial state. .

The operation of the conventional tape feeder configured as described above is as follows.

First, the cover 30 is lifted so that the feed hole 61 formed in the tape 60 is fitted into the protrusion 21 formed in the driving wheel 20, and then the cover 30 is closed, and then the stepping motor 40 is closed. When the rotating shaft 41 of the stepping motor 40 is rotated in the forward direction by operating the drive force of the stepping motor 40 is switched by the power switching means 70 from the rotational movement to the linear movement slider 50 ), The slider 50 moves forward. Then, the slider 50 is advanced by the set stroke, that is, the distance between the centers of the indentation grooves 62 formed in the tape 60, so that the lever 23 coupled to the slider 50 is a projection of the ratchet wheel 26. The driving wheel 20 fixed to the same axis 22 as the ratchet wheel 26 is rotated in a counterclockwise direction while advancing together with the slider 50 while being engaged with the 21.

At this time, the tape 60 in which the transfer hole 61 is inserted into the protrusion 21 of the driving wheel 20 is advanced in a predetermined amount so that the vinyl 64 of the tape 60 is peeled off, and the opening 32 of the cover 30 is removed. At the same time, the electronic component 63 embedded in the recess 62 of the tape 60 is exposed to the outside through the opening 32 of the cover 30, and is rotated to the frame 10. The ratchet 25, which is possibly installed, is pushed by the projection 21 formed on the ratchet wheel 26 as the ratchet wheel 26 rotates to tension the second elastic member 27 and at the same time, the groove of the ratchet wheel 26. The lever 23 is squeezed out as far as possible and is caught between the projections 21 of the ratchet wheel 26 to prevent the ratchet wheel 26 from rotating clockwise upon restoration of the slider 50. .

Further, in this state, when the rotating shaft 41 of the stepping motor 40 is rotated in the reverse direction, the driving force of the stepping motor 40 is switched by the power switching means 70 from the rotational movement to the linear movement slider And the slider 50 is retracted in the rearward direction to be returned to the initial state, and the lever 23 which is bound to the protrusion 21 of the ratchet wheel 26 moves to the first elastic member 24. While being tensioned, the slider 50 is restored by being rotated clockwise about the pin 23a.

At this time, since the ratchet 25 is inserted between the protrusions 21 of the ratchet wheel 26 during the operation as described above, the driving wheel 20 is not rotated in the tape 60 direction and remains in a stopped state. The tape 60 is conveyed by one pitch in accordance with the forward and reverse driving of the motor 40.

However, the conventional tape feeder configured as described above does not include a recovery means for separately collecting the vinyl 64 covering the recess 62 of the tape 60 in which the electronic component 63 is embedded. The tape 60, which is separated from the vinyl 64 which is taken out to the outside through the opening 32 of the cover 30, is conveyed from one tape feeder in the process of operating a plurality of tape feeders at the same time. Since the peeled off vinyl 64 is transported to another tape feeder and is entangled at the same time, the operation of the plurality of tape feeders is stopped and then the vinyl 64 of the tape 60 has to be collected and restarted.

The present invention has been proposed in view of the above problems, and an object thereof is that the tape feeder peels off the vinyl covered on the upper surface of the tape by a predetermined interval while transferring the tape by one pitch, and then embedded in the recess groove of the tape. In the case of allowing the picker to pick up the head unit is to provide a vinyl recovery apparatus of the tape feeder for the surface mounter configured to easily recover the vinyl of the tape.
