Abstract

PURPOSE:To stably supply electronic parts using a tape tap member by providing a long hole so as to enable the tape tap member to be transferred corresponding to the thickness to the taping at the time of feeding the taping which houses electronic parts by a parts cassette. CONSTITUTION:A tape tap member 5 is always activated in the direction of an illustrated arrow A so as to come in contact with the upper surface of the taping 3 provided on a parts cassette 4. A turning support 11 of the tape tap member 5 is supported by a long hole 9. The turning support 11 transfers up and down inside this long hole 9 so as to transfer the contact face 10 with the taping 3 almost vertically in the illustrated direction B or C according to the thickness of the taping 3. Accordingly, the surface of the taping 3, whose top tape 7 is removed, is controlled by the tape tap member 5 so as to remove rising and projecting of electronic parts 1 housed in the taping 3. Thereby, electronic parts 1 can be stably fed.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component suction device used in a component insertion device for mounting electronic components on a printed circuit board.

0002

[Background Art] Recently, as electronic components have become more and more chip-based, components of various shapes and sizes have come into existence, and even small components with dimensions of only about 1 mm need to be mounted on printed circuit boards by suction. It has become.

[0003] The conventional technology will be explained below with reference to the drawings. FIG. 2 shows the configuration of a conventional electronic component suction device. As shown in the figure, the electronic component 1 is attracted by the nozzle 2. The electronic component 1 is supported by taping 3, and the taping 3 is supplied from a parts cassette 4. The parts cassette 4 is provided with a tape pressing member pressed by an elastic member 6, and the electronic component 1 supported by the taping 3 is covered with a top tape 7, and the electronic component 1 is covered with a top tape 7 immediately before the component 1 is sucked into the nozzle 2. The top tape 7 is then wound up by a take-up reel 8. Next, the operation of the electronic component suction device configured as above will be explained. First, top tape 7 is
The electronic component 1 supported by the taping 3 after being wound up by the take-up reel 8 is supported by the main body of the parts cassette 4 and pressed by the tape pressing member 5 by the elastic member 6.
The suction nozzle 2 is moved to the suction position while its rise is restricted from the bottom surface, and finally the suction nozzle 2 descends from above.
sucked up by Generally, the thickness of the taping varies depending on the size of the electronic component to be supported. Therefore, in the past, it was necessary to change the mounting height of the tape holding member to accommodate these different sized parts.

0004

[Problems to be Solved by the Invention] However, in such a conventional configuration, the thickness of the taping 3 is different in order to support electronic components 1 of different sizes, and the mounting height has to be adjusted to accommodate the taping 3. It was necessary to prepare many types of different tape pressing members 5. In addition, the tape pressing member 5
Due to the machining accuracy, a gap is generated between the tape holding member 5 and the top surface of the taping 3, and this gap has a high possibility that the electronic components will stand up due to vibration.
Therefore, there has been a problem in that it is difficult to constantly and stably supply electronic components.

The present invention solves these problems, and even if the thickness of the taping changes or even if the tape pressing member is not flat, the tape pressing member can be used stably. It is an object of the present invention to provide an electronic component suction device capable of supplying electronic components.

[0006]

[Means for Solving the Problem] In order to solve this problem, an electronic component suction device of the present invention includes a nozzle for suctioning an electronic component, a taping for storing the electronic component, and supplying the taping to a suction position. A parts cassette, a tape holding member provided in the parts cassette and in contact with the taping substantially horizontally, and a vertically movable elongated hole, the holding member moving up and down in accordance with the thickness of the taping. It was designed to do so.

[0007]

[Operation] With this configuration, when picking up electronic components from taping, at least one tape pressing member is pressed tightly against the top surface of taping of different thickness.
Housed within taping of different thicknesses,
It becomes possible to keep the clearance generated between the electronic component and the tape pressing member constant, and as a result, the electronic component can be stably supplied.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of an electronic component suction device according to an embodiment of the present invention. In FIG. 1, parts that are the same as those in the conventional configuration shown in FIG. 2 are given the same reference numerals, and description thereof will be omitted. As shown in FIG. 1, the tape pressing member 5 includes an elastic member 6
Therefore, it is always urged in the direction of arrow A and is in contact with the upper surface of the taping 3. 9, a pivot point 11 of the tape pressing member 5 is supported by an elongated hole 9, and as the pivot point 11 moves up and down in the elongated hole 9, the contact surface 10 with the taping is Depending on the thickness of the taping 3, it can move approximately perpendicularly to the B or C direction.

As described above, according to this embodiment, when the electronic component 1 is fed, the rotation fulcrum 11 moves in the elongated hole 9 provided to support the rotation fulcrum of the tape holding member 5. Then, the tape pressing member 5 becomes movable up and down. With this configuration, the upper surface of the taping 3 from which the top tape 7 has been peeled off is restricted by the tape pressing member 5, thereby preventing the electronic components stored in the taping 3 from standing up or protruding. It is also possible to eliminate lifting of the electronic component 1, and as a result, the electronic component 1 can be stably supplied.

0010

[Results of the Invention] As is clear from the above description of the embodiments, according to the present invention, when a tape containing electronic components is supplied using a parts cassette, the tape pressing member moves in accordance with the thickness of the taping. Since the elongated hole is provided to make this possible, there is no need to change the tape pressing member depending on the difference in taping thickness. Further, even if the flatness of the taping contact portion of the tape pressing member is not accurate, a remarkable effect can be obtained in that the tape pressing member can stably press the taping top surface while remaining in close contact with the taping top surface.
