Abstract

PURPOSE:To surely take out a wire rod whose posture is unstable one by one from a stocker and supply it to the following process by providing a vibrator for giving lateral vibration to the stocker, and an attracting nozzle having a groove having the same diameter as the wire rod in the stocker on the top end to vacuum attract the wire rod. CONSTITUTION:A stocker 1 is laterally vibrated by a vibrator 5, whereby wire rods 9 in the stocker 1 regularly hold the upper surface horizontally by the vibration, and this vibration plays the role of preventing the entanglement of the wire rods 9 in the stocker and preventing the double taking by the entanglement of the wire rods 9 at raising an attracting nozzle 6. The attracting nozzle 6 has a semicircular groove having the same diameter as the wire diameter of the wire rod 9 so that the wire rods 9 are surely vacuum-attracted by lowering a vertically moving guide 7. The attracting nozzle 6 carries the wire rods 9 to the following process stage after it is raised by the vertically moving guide 7 and a longitudinally moving guide 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire feeding device, and more particularly to a feeding mechanism for a cut fixed-size wire used for soldering work.

[0002]

2. Description of the Related Art Conventionally, as a method of supplying this type of wire,
There is a method of directly pulling out a wire from a long reel material with a roller or the like, soldering and joining, and then cutting the wire.

[0003]

The above-mentioned conventional method of directly drawing a wire material from a long reel material to supply the wire material causes unstable feeding due to winding of the wire material by the reel, clogging of covering dust by strip processing, and the like. Therefore, variations in cutting dimensions and chucking defects occur, and conduction defects due to misalignment occur during soldering work. Further, although it is suitable for a thin wire such as a wire for an electronic circuit which is mechanically easy to handle, it is not suitable for a thick wire, so that it has a drawback that it requires manual work.

The present invention eliminates the above-mentioned conventional drawbacks and provides a vacuum type wire rod supply mechanism for stably supplying a wire rod for soldering work.

[0005]

DISCLOSURE OF THE INVENTION A vacuum type wire rod supply mechanism of the present invention comprises a stocker for storing cut wire rods, a moving means for moving the stocker up and down, and a vibrator for applying a horizontal vibration to the stocker. And a suction nozzle for vacuum-sucking the wire rod by providing a groove having the same diameter as the wire rod in the stocker at the tip, and a guide and drive means for moving the suction nozzle up and down and front and back.

[0006]

The present invention will be described below with reference to the drawings.

1A and 1B show an embodiment of the present invention. FIG. 1A is a front view and FIG. 1B is an enlarged sectional view showing a sucked state of a wire.

As the structure of this embodiment, the cut wire rod 9 is used.
A stocker 1 for storing a stocker is installed in a vertical guide unit 4, and an elevator section 2 as a drive source for the stocker 1 is provided in the lower part and is supported by a support rod 3. Further, a vibrator 5 is provided on the side surface of the stocker 1, and transmission of vibration to the housing base 11 is prevented by interposing a vibration-proof rubber 10. A suction nozzle 6 for sucking the wire material 9 is provided on the upper part of the stocker 1, and the suction nozzle 6 is installed in a vertical movement guide 7 and a front-back movement guide 8.

As the operation of this embodiment, the stocker 1 is vibrated in the left and right directions by the vibrator 5, and the wire 9 in the stocker 1 always keeps its upper surface horizontally due to the vibration. It plays the role of preventing the entanglement of the wire rods 9 and preventing the two wire rods 9 from being entangled when the suction nozzle 6 rises. The suction nozzle 6 is provided with a semicircular groove having the same diameter as the wire diameter of the wire rod 9 so that the wire rod 9 can be surely vacuum-sucked by the downward movement of the vertical movement guide 7. The suction nozzle 6 conveys the wire 9 to the next process stage after the suction nozzle 6 is lifted by the vertical movement guide 7 and the front-back movement guide 8.

[0010]

As described above, according to the present invention, by sucking the wire rods in a vacuum method while vibrating them, the wire rods whose postures are not fixed can be reliably taken out one by one from the stocker and supplied to the next step. There is an effect that can be. This effect makes it possible to stabilize the positioning chucking work of the wire rod in the next step and facilitate automation in the soldering of the lead wire particularly in the assembly of the electric circuit component.
