Abstract

PROBLEM TO BE SOLVED: To provide a brazing material cut-out and alignment device which hardly move unstably when the brazing material using for bonding of a laser diode is cut out from a reel. SOLUTION: In a device in which after the brazing material is passed through from a gold-tin reel 1 to a guide 2, and is clamped and cut out, it is reversed by a reversing arm 9 and aligned on an adhesive tape 12, the brazing material hardly move unstably when it is released, owing to providing two clampers 3 and 4 and maintaining the brazing material with either one clamper whatever the timing is.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to an apparatus for processing a brazing material used for bonding a laser diode.

[Related Art] In bonding of a laser diode, a chip is welded to a stem base using gold tin as a brazing material. In the automatic bonding apparatus, the method of supplying the brazing material includes: A) supplying the brazing material in a ball shape; and B) supplying the brazing material in a chip shape and placing it on a tray. C) Cut out the raw material wound in a reel shape one by one,
This tape is supplied by aligning and pasting it on an adhesive tape. (Method of the present invention). Among these three, the most stable is C). However, in the conventional brazing material cutting and aligning machine, there are many unstable movements for feeding the brazing material and removing the cut brazing material.

[Problems to be solved by the invention]
The mechanism for pulling out the raw material from the reel and sending it to the cutting blade is as follows: A) A mechanism to send it between two rollers, B) A mechanism to send it between clampers, but A)
Since the distance between the position where the roller is sandwiched and the position of the blade cannot be shorter than the radius of the roller, the unconstrained length of the brazing material becomes longer and becomes unstable. B) is more stable than A), but in the prior art, since there was only one clamper, the row material was released at a certain timing, causing an unstable movement at this time. In addition, when taking out the cut brazing material, conventionally, while cutting the brazing material here, the brazing material was cut, and it was sucked out with a suction cup. The row material is displaced the moment it is cut.-When removing, the cut end of the cut row material is caught on the blade and dropped.

[0004] It is an object of the present invention to solve these two points and to stably cut and align brazing materials.

[Means for Solving the Problems] In order to achieve the above object, two or more clampers are provided, and a method is employed in which a cut brazing material is taken out by a reversing arm.

As shown in FIG. 1, two clampers, a clamper (1) and a clamper (2), are provided, and any one of the clampers clamps the brazing material at any time, so that the brazing material is released. Eliminate unstable movement.

The reversing arm presses the brazing material to be cut by the arm pusher before the upper blade is lowered, so that the brazing material at the moment of cutting is not displaced. The lower sucker keeps away from the blade while holding down, so that the cut material does not touch the blade and fall.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the drawings based on an embodiment. FIG. 1 is an apparatus configuration diagram of the present invention. The movement will be briefly described. The brazing material wound on the gold-tin reel is fed between the upper blade and the lower blade while being clamped by the clamper (1) and the clamper (2) through the guide, and cut by the upper blade and the lower blade. The cut gold-tin chip taken out by the reversing arm and adsorbed by the reversing arm is adsorbed by the sticking arm and aligned and stuck on the adhesive tape.

[Effect of the Invention] Unstable movement is eliminated,
It became a reliable machine.

[Brief description of the drawings]

FIG. 1 When the upper blade is in contact with the lower blade and the brazing material is cut, the cut brazing material is firmly pressed by the reversing arm and the lower suction cup, so that it does not shift.

FIG. 2 shows that the cut brazing material moves away from the upper blade and the lower blade while being pressed by the reversing arm and the lower suction cup. At this point, the suction cup of the reversing arm is suctioned by vacuum, and the lower suction cup is blowing.

FIG. 3 shows that the reversing arm and the lower suction cup are further away from the blade, and the reversing arm is adsorbing the brazing material (gold-tin chip) which has been cut open from the lower suction cup.

FIG. 4 is a side view of the reversing arm, in which the sticking arm sucks the gold-tin chip and aligns and sticks the chip on the adhesive tape;

FIG. 5 shows the clamper (1) opened, backed and closed.

FIG. 6 opens, backs, and closes the clamper (2).

FIG. 7: clampers (1) and (2) feed the brazing material.
