However, in the above-mentioned conventional configuration, when the electronic component 1 becomes large, the pitch P between the electronic components 1 shown in FIG. However, the required winding amount of the cover tape 3 also increases, but there is a limit to the amount of the cover tape 3 that can be wound by one winding operation. However, it has a problem that it cannot be applied to the electronic parts of.

The present invention solves the above-mentioned conventional problems. Even when a large electronic component is supplied, the cover tape can be wound up for one pitch of the large electronic component by one winding operation. It is an object of the present invention to provide an electronic component supply device capable of

A guide unit that guides taping electronic components, a conveyance unit that conveys taping electronic components guided by this guide unit, and a conveyance path that conveys this taping electronic components, in front of the take-out position where individual electronic components are sequentially taken out. A cover tape take-up unit including a peeling unit for peeling the cover tape fixed to the provided taping electronic component and a take-up reel for winding the peeled cover tape with a planetary gear mechanism to increase the amount of rotation. It is composed of.

[0010]

With this structure, it is possible to wind the cover tape by transmitting a movement amount larger than that of the ratchet moved by the ratchet pawl that drives the cover tape winding portion, to the reel for winding the cover tape. Therefore, the winding amount of the cover tape required for a large electronic component can be wound in one operation.

Is a ratchet gear 14 rotatably assembled to a fulcrum shaft 16 arranged at the tip of the main body frame 10 while contacting the lower surface of the tape guide 11 attached to the side plate 23.
The carrier tape feed gear 13 coupled to the ratchet gear 14 meshes with the carrier hole 4 of the carrier tape 2 holding the electronic component 1 and is engaged with the carrier tape holder 15 as the ratchet gear 14 rotates. The transport unit is configured so that the taping electronic components 5 guided by the carrier tape feed gear 13 are sequentially fed.

A link 19 is attached to the drive lever 12.
Is connected, and the other end of the link 19 is connected to the ratchet lever 17.

The pin 25 is attached to the drive lever 12. The drive lever 12 is connected with a lever 26, a link 27, and a ratchet lever 28, and a ratchet pawl 31 is attached to the tip of the ratchet lever 28. Has been.

Further, the take-up reel 34 for the cover tape 3
Shares a fulcrum shaft 33 and is attached to the back side of a ratchet 32 that is rotated by the ratchet pawl 31 to form a cover tape winding portion 35. Reference numeral 29 in the drawing is a spring for returning the drive lever 12 to its original position, and reference numeral 30 is a spring attached for returning the link 27 to its original position.

FIG. 2 is a front view showing the details of the cover tape winding portion 35. In FIG. 2, the ratchet lever 28 is rotatably mounted by a fulcrum shaft 33, and one end of the ratchet lever 28 is connected to the link 27. The end is the fulcrum pin 41
Is connected to a ratchet pawl 31 that is rotatably attached.

The fulcrum pin 4 mounted on the side plate 23
The ratchet claw 43 rotatably attached by 2 meshes with a groove (not shown) formed in the outer circumference of the ratchet 32 so that the ratchet 32 rotates counterclockwise but not clockwise. Has become.

3 (a) and 3 (b) are a front sectional view and a side sectional view showing the planetary gear mechanism of the cover tape winding portion 35. In FIGS. 3 (a) and 3 (b), the sun gear 51 is a fulcrum. It is fixed to the side plate 23 by the pin 56 attached to the shaft 33, the carrier 54 is attached to the ratchet 32 by the pin 55 attached to this carrier 54, and the cover tape take-up reel 34 is attached to the pin 57.
Is attached to the internal gear 53 by the planetary gear 5
2 is stored in the carrier 54.

In the cover tape take-up portion 35 thus constructed, the planetary gear 52 is at the G1 point, and at that time, the intersection point with the cover tape take-up reel 34 passes through the G1 point from the center of the fulcrum shaft 33 and the G2 point. As the ratchet pawl 31 moves the ratchet 32 in the direction of arrow F, the pin 54 fixed to the ratchet 32 moves the carrier 54 and the planetary gear 52 housed in the carrier 54.
Moves from point G1 in FIG. 3 to point H1 in FIG. When this movement rotation angle is θ1, G2 which is the intersection of the center of the fulcrum shaft 33 and the cover tape take-up reel 34 shown in FIG.
The point is accelerated according to the gear ratio of the sun gear 51, the planetary gear 52, and the internal gear 53, and is moved to the point H2 indicated by the moving rotation angle θ2 in FIG.

With the structure of the cover tape take-up unit 35 using the planetary gear mechanism, the cover tape take-up reel 34 is provided with a rotation angle θ2 larger than the rotation angle θ1 of the ratchet 32 rotated by the ratchet pawl 31. It is possible to wind the cover tape in a single operation, which is required for large electronic components.
The rotation angle θ2 can be arbitrarily adjusted by changing the tooth number ratio of each of the above gears, and electronic components of different types can be freely supported.

The taping electronic component 5 according to this embodiment is composed of a carrier tape 2 and a cover tape 3 attached to the upper surface thereof.
However, the present invention is not limited to this, and a cover tape in the case of a taping electronic component composed of a tape mount and a cover tape attached to the upper surface thereof, or It goes without saying that the same can be applied to an adhesive tape in the case of a taping electronic component configured to be fixed with an adhesive tape via a carrier tape provided.

[0022]

According to the electronic component supplying apparatus of the present invention having the above-described structure, in the case of a large electronic component, the required winding amount of the cover tape can be wound in a short time by one winding operation. Therefore, productivity can be improved.

Further, even if the diameter of the cover tape take-up reel is made small, the effect can be sufficiently exerted, and it becomes possible to take up more cover tapes than the conventional case.
The number of times the cover tape wound around the cover tape take-up reel is removed and discarded is reduced, and the operating rate is improved.
