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 a mounting component onto 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 picks up a mounting part embedded in the recess of the tape.

In general, the surface mounter is a core equipment of the surface mount assembly equipment for mounting a surface mounting device (SMD) on a printed circuit board. The surface mounter receives various mounting parts from a component supplier and transfers them to the mounting position of the printed circuit board. A device for mounting on a circuit board, the configuration of which is largely a tape feeder for supplying mounting components, an XY table portion for determining a work position, a conveyor portion for conveying a printed board to be worked on, and a mounting component from a tape feeder. And a head portion to be picked up and mounted on a printed circuit board.

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 mounting parts in the recess. 1 is rotatably coupled to the frame 10 as shown in Figure 1 drive wheel 20 for transporting the tape 60, the hinge 31 is rotatably coupled to the upper end of the frame 10 and the tape A cover 30 having an opening 32 through which a vinyl 64 covering the recessed groove 62 of the tape 60 is ejected while the mounting component 63 embedded in the recessed groove 62 of the 60 is exposed. And a stepping motor 40 installed on the frame 10 to repeatedly rotate the forward and reverse directions for a predetermined time, and the power switching means 70 for switching the rotational motion of the stepping motor 40 into a linear motion. ) And a power switching means 70 according to the driving of the stepping motor 40. The slider 50 which linearly reciprocates by an operation, and the ratchet wheel 26 rotatably installed on the slider 50 and fixed to the same axis 22 as the driving wheel 20 when the slider 50 is moved forward. It is connected between the lever 23 for rotating the slider and the slider 50 and the lever 23 to maintain the latched state with the ratchet wheel 26 when the slider 50 is advanced and at the time of restoring the slider 50. In the first elastic member 24 for reducing the lever 23 to the initial state, and rotatably installed on the frame 10 is caught by the ratchet wheel 26 during the restoration of the slider 50 drive wheel 20 ) And a second elastic member 27 connected between the frame 10 and the ratchet wheel 26 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. Then, the cover 30 is closed and then the stepping motor 40 is closed. When the rotating shaft 41 of the stepping motor 40 rotates in the forward direction, the driving force of the stepping motor 40 is switched from the rotational movement to the linear movement by the power switching means 70, the slider 50. The slider 50 is forwardly moved forward, and then the slider 50 is advanced by the set stroke, that is, the distance between the centers of the recesses 62 formed in the tape 60 and coupled to the slider 50. The driving wheel 20 fixed to the same axis 22 as the ratchet wheel 26 is fixed while the lever 23 is advanced with the slider 50 while being engaged with the protrusion 26a of the ratchet wheel 26. The angle is rotated counterclockwise.

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 mounting part 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 protrusion 26a 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 it can and is caught between the projections 26a of the ratchet wheel 26 to prevent rotation of the ratchet wheel 26 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 projection 26a 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, the ratchet 25 is inserted between the projections 26a of the ratchet wheel 26 in the above operation, so that the driving wheel 20 is not rotated in the direction of the tape 60 and remains stopped. 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 have a recovery means for separately collecting the vinyl 64 covering the recesses 62 of the tape 60 in which the mounting parts 63 are 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 problems described above, and its purpose is to remove the vinyl covered on the upper surface of the tape by a predetermined interval while the tape feeder transfers the tape by one pitch, and then the mounting part 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.
