Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention applies to leadless type electronic components such as chip resistors and chip multilayer capacitors.
The present invention relates to a taping cassette type component supply device that is mainly used in an electronic component mounting machine that mounts electronic components onto a board constituting an electronic circuit.

Conventional technology For electronic component mounting machines, the conventional technology
A taping cassette type component supply device as shown in Japanese Patent No. 118698 is used.

As shown in FIG. 6, the taping cassette A in this taping cassette type component supply device has a tape body a with a large number of component accommodating portions b formed in one row at a predetermined pitch, into which electronic components c are loaded. In addition, the electronic component c is held by a sealing tape d and a holding tape e attached to the front and back surfaces of the tape body a. Further, feed holes (not shown) are formed at a predetermined pitch on the side edge of the taping cassette A.

In the electronic component mounting machine, the taping cassette A is intermittently fed in one direction as shown in FIG. Reference numeral g designates a feeding device that engages with the feed hole and moves the taping cassette A intermittently, and h designates a device that peels off the sealing tape d.

The electronic component c loaded into the component housing part b is sucked by a vacuum chuck (pickup means) i, and after being taken out from the taping cassette A,
It is mounted at a predetermined position on the substrate j by the vacuum chuck i.

Problems to be Solved by the Invention However, according to the above-mentioned conventional example, it is difficult to reliably pick up the electronic component c using the vacuum chuck i due to the diversification of electronic components c and their increasing size. It may become. For example, a semi-fixed polyimide chip (electronic component) c has a screwdriver groove f on its top surface as shown in FIG.
There is a problem in that the suction force of the vacuum chuck i becomes insufficient due to air leakage through the groove f, making pickup uncertain. In addition, the top surface of the electrolytic capacitor chip (electronic component) c may be concave in the shape of a bowl, and in this case as well, there is a problem that the suction force of the vacuum chuck i does not work sufficiently and the pick-up becomes uncertain. be. This problem becomes more noticeable as the electronic component c becomes larger and weighs more.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a taping cassette that is intermittently fed in one direction with a large number of component storage sections, stores components in these component storage sections, and picks up the taping cassette. In a taping cassette type parts supply device configured to pick up the parts sent to a position with a pick-up means, the pick-up means is constituted by a picking device equipped with chuck claws for gripping both sides of the part, and The present invention is characterized in that spaces are formed on both sides of the parts storage portion of the cassette for the chuck pawl to pass through.

Effect As a result of the present invention having the above configuration, parts such as electronic components can be picked up from a taping cassette using a pick-up device equipped with chuck claws, and the chuck claws can be passed through both sides of the parts storage portion of the taping cassette. Since a space is formed for this purpose, the chuck claw of the extracting device can be smoothly operated. In addition, it has the effect of being able to reliably pick up parts that have driver grooves or depressions on the top surface.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The embodiments of the invention shown in FIGS. 1-4 relate to implementation in an electronic component mounting machine. In this embodiment, the taping cassette 1 has a large number of component housing portions 3 formed in one row at a predetermined pitch on a synthetic resin tape body 2, into which electronic components 4 are inserted, and at the same time, the electronic components 4 are placed on the surface of the tape body 2. The electronic component 4 is held by the attached sealing tape 5. Further, feed holes 7 are formed at a predetermined pitch on the side edge of the taping cassette 1. The taping cassette 1 of this embodiment differs from the one shown in FIG.
It is integrally formed with the holder, eliminating the need for retaining tape.

Grooves 8 are formed on both sides of the component accommodating section 3 of the taping cassette 1, the inner end communicating with the component accommodating section 3 and the outer end open to the outside. This groove 8 becomes a space through which a chuck pawl 9, which will be described later, passes.

The taping cassette 1 is intermittently fed in one direction as shown in FIG. Reference numeral 10 denotes a feeding device that engages with the feed hole 7 and moves the taping cassette 1 intermittently, and 11 is a device that peels off the sealing tape 5.

The electronic component 4 loaded into the component storage section 3 is gripped by a pick-up means 12 consisting of a pick-up device equipped with a pair of chuck claws 9, and after being taken out from the taping cassette 1, is picked up by the pick-up device 12. It is attached to a predetermined position on the board 13.

As shown in FIGS. 3 and 4, the extracting device 12 has a pair of chuck claws 9 pivoted to a support 15 via pivot shafts 14, and a proximal end 16 of each of the chuck claws 9 to an operating rod of an air cylinder 17. 18, and the pair of chuck pawls 9 can be opened and closed by the vertical movement of the operating rod 18, but the mode is not limited thereto. The chuck claw 9 of the extracting device 12 grips both sides of the electronic component 4 and picks it up. Also, at this time, the chuck pawl 9 can pass through the groove 8 without any problem.

The present invention can be configured in various ways other than those shown in the embodiments. For example, as shown in Figure 5,
Taping cassette 1 with holding tape 19
The present invention can be applied to a component supply device using a. In this case, a slit-like space 8b is formed in the tape body 2, and this space 8b becomes a space for the chuck pawl to pass through.

Furthermore, although the above embodiment relates to a supply device for electronic components 4, it is also possible to apply the present invention to a supply device for components having the same problems as the electronic components 4.

Effects of the Invention Since the taping cassette type component supply device of the present invention has the above configuration, even if the shape of the component is not suitable for vacuum suction, the chuck claw of the extraction device can reliably pick up the component in the taping cassette. It has the effect that it can be picked up and that the picking up operation of the chuck claw can be carried out smoothly.
