The utility model discloses a pressing claw fixture for an ultrasonic aluminium wire press welder, and the fixture comprises a lower locating plate and a pressing claw, the pressing claw is divided into an interconnecting piece and a claw part, and the claw part is provided with at least two bending claws whose ends bend oppositely to each other; the bent ends respectively correspond to the side brims of the welding ends of the left pin and the right pin of a weld assembly transistor; 2-4 bending claws or two more straight claws which are added are also available, which separately stick and compress the welding ends of the left pin and the right pin of the transistor on the lower locating plate from the both sides, the outer side and the rear side; thanks to that two, three, even four bending claws are added to the existing pressing claw with only two straight claws, the welding ends of the left pin and the right pin of the transistor can be compressed tightly on the lower locating plate of the welding fixture from two to three directions, thereby insuring the welding ends of the pins without adrift when soldering, and greatly improving the pressing weld quality of the ultrasonic aluminium wire press welder.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly relates to a kind of ultrasonic aluminum wire press welder paw anchor clamps.
Background technology
In transistorized production process, the pin that need from chip, go between, lead-in wire generally is an aluminium wire, this measure is exactly that the two ends that will go between are soldered on chip extraction electrode and the pin, welding generally is to adopt the ultrasonic bonding form, and ultrasonic bonding requires welded part closely to contact, and it is loosening not have; In the prior art, generally be that a plurality of transistorized arrangements of chips are bonded on the bar shaped substrate of a drawing with embarking on journey, be a plurality of chips on one side on the bar shaped substrate, another side is corresponding each chip and three of making draw pin, middle pin is connected with the die bottom surface electrode, the left and right sides pin of both sides is unsettled, pin is elongated flat, unsettled welding ends is bigger, each chip and pairing transistor link together on the bar shaped substrate, afterwards on two electrodes and left and right sides pin that the chip that two aluminium wires is welded on the chip end face by the employing ultrasonic aluminum wire press welder is drawn, when welding, design has anchor clamps, it comprises location-plate and paw down, and the effect of following location-plate is that the bar shaped substrate is fixed, and the effect of paw is to press card to be pressed on down on the location-plate so that welding left and right sides pin; Paw can be divided into connecting portion and claw, connecting portion is in order to fixedly connected paw with press welder, claw compresses the left and right pin of transistor in order to overlay, existing paw be shaped as rectangular flap, be shaped on the claw perpendicular to broken line and corresponding to the straight pawl (the straight pawl number of common paw is two) of the left and right pin of transistor; Straight pawl will be the cantilever beam shape left and right pin, be pressed in down on the location-plate from stiff end top half pin, pressure welding aluminium wire then, the last stamping-out of process again will connect each chip on the bar shaped substrate and three connections of drawing between the pin are cut off, and just can obtain welding the transistor of pinout.Certainly these actions all are semiautomatic controls.In process of production, find that existing paw has its weak point: because straight pawl is to be pressed in down on the location-plate from the stiff end top that is cantilever beam shape left and right sides pin with half of pin, the welding ends of pin still is the cantilever beam state, welding ends was loosening sometimes when so pin was crushed on down on the location-plate, cause welding effect poor, easily produce substandard products.
The utility model content
The purpose of this utility model, be to provide a kind of simple in structure, the pin welding ends can not become flexible when compressing, and guarantees the ultrasonic aluminum wire press welder paw anchor clamps of welding effect.
The purpose of this utility model is achieved by the following technical programs: ultrasonic aluminum wire press welder paw anchor clamps of the present utility model, comprise location-plate and paw down, paw can be divided into connecting portion and claw, it is characterized in that: described claw has at least two radicles curved pawl of corresponding bending in opposite directions; Each lateral edges of the end of bending corresponding to the left and right pin welding ends of welded part transistor.
The utility model advantage compared with prior art is: owing to Duoed two, three even four curved pawls than the existing paw that has only two straight pawls, can it be pressed on the following location-plate of weld jig tightly from two, three directions of transistor pin welding ends, the pin welding ends can not become flexible when guaranteeing to weld, and can improve ultrasonic wave aluminium wire pressure welding quality greatly.
