Abstract
The utility model relates to a welding device of a lead frame. Innovation points are that: the welding device comprises a bottom plate, a support plate and a welding head, wherein the welding head is connected with an elevating device of a welding machine; the bottom plate is formed and connected with the support plate; the welding head is connected with the support plate in a way of sliding up and down through a sliding guide rail pair; the bottom surface of the welding head is provided with two pressure welding points formed bilaterally symmetrically; the left side and the right side of the upper plane of the bottom plate are provided with a plurality of symmetrically-arranged positioning needles respectively; the positioning needles correspond to positioning through holes formed on both sides of the lead frame; and the distance between the pressure welding points on the left side and the pressure welding points on the right side is equal to the distance between the positioning needles on the left side and the positioning needles on the right side of the lead frame. The welding device has the advantages of reducing material waste of the lead frame and reducing the replacing time of the lead frame.
Description
Technical field
The utility model relates to a kind of welder, is specifically related to a kind of welder of lead frame.
Background technology
Along with the continuous development of semiconductor fabrication techniques, high speed, microminiaturization and Surface Mounting Technology are just progressively moved towards in semi-conductive follow-up encapsulation, the existing thin type winding lead frame that uses distribution density high in a large number of generally all needing in process of production.But because the draw-gear of winding loader framework generally all has 60 ~ 80cm apart from soldering tip, and the lead frame of this segment length generally all can't load, therefore can cause the waste of lead frame some, generally changing a new lead frame in process of production also can cause the head of lead frame and the waste of afterbody some, nearly 1 ~ the 1.5m of length of the lead frame of waste, and change a lead frame and generally need time spent 3 ~ 5min, therefore when large-scale production owing to change lead frame, not only can cause a large amount of raw material and waste of time, and cause the raising of production cost.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce blaster fuse frame material waste and reduce and change the lead frame time, and be applicable to the winding loader connect the welder of lead frame, to overcome the deficiency of prior art.
In order to achieve the above object, the technical solution of the utility model is: a kind of welder of lead frame, its innovative point is: comprise base plate, support plate and with the plumb joint of the lowering or hoisting gear load of bonding machine, described base plate and support plate load, plumb joint connects by secondary the sliding up and down with support plate of rail plate, the plumb joint bottom surface is provided with two pressure welding point that are symmetrically arranged, the plane each side is provided with the pilot pin of several symmetric arrangement on the base plate, and the set positioning through hole in described pilot pin and lead frame both sides is tackled mutually; Distance between the pressure welding point of the described left and right sides equals the distance between the pilot pin of the lead frame left and right sides.
In technique scheme, described plumb joint slides up and down the rail plate auxiliary structure that cooperates with support plate multiple implementation, and the rail plate that the utility model is preferentially selected for use is secondary to be swallow-tail form rail plate pair, but is not limited thereto.
The good effect that the utility model had is: when the utility model uses, the afterbody of lead frame is fixed on the base plate, and the head of a new lead frame overlaps fixing with its afterbody, drive the lowering or hoisting gear of bonding machine, make plumb joint move downward, pressure welding point is welded overlapping the zone heat that has a resistance by output current, need not to use any scolder, not only speed of welding is fast, and smokeless environment-friendly, and the lead frame after the welding can smooth and easyly be sent in the guide rail of winding loader, so not only reduce the waste of blaster fuse frame material, also significantly reduce because of changing the time that lead frame is wasted, reduced production cost, improved productivity.

Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of lead frame, and wherein, Fig. 3 a is the schematic diagram before the lead frame welding, and Fig. 3 b is the schematic diagram after the lead frame welding, and 5 is lead frame, and 5-1 is a welding ends, and 5-2 is a positioning through hole.
The specific embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of welder of lead frame, comprise base plate 1, support plate 2 and with the plumb joint 3 of the lowering or hoisting gear load of bonding machine, described base plate 1 and support plate 2 loads, plumb joint 3 slides up and down by rail plate secondary 4 and support plate 2 and connects, plumb joint 3 bottom surfaces are provided with two pressure welding point 3-1 that are symmetrically arranged, and the plane each side is provided with the pilot pin 1-1 of several symmetric arrangement on the base plate 1, and the set positioning through hole 5-2 in described pilot pin 1-1 and lead frame 5 both sides tackles mutually; Distance between the described left and right sides pressure welding point 3-1 equals the distance between lead frame 5 left and right sides pilot pin 1-1.
As shown in Figure 1, 2, slide up and down at support plate 2 for the ease of plumb joint 3, described rail plate secondary 4 is a swallow-tail form rail plate pair.
When the utility model uses, pilot pin 1-1 on the base plate 1 is inserted in the positioning through hole 5-2 of lead frame 5 both sides, the head of another lead frame 5 overlaps with its afterbody and is fixed on (as shown in Figure 3) on the base plate 1, at this moment, drive the lowering or hoisting gear of bonding machine, make plumb joint 3 move downward, pressure welding point 3-1 welds overlapping the zone heat that has a resistance by output current, need not to use any scolder, not only speed of welding is fast, and smokeless environment-friendly, and the lead frame 5 after the welding can smooth and easyly be sent in the guide rail of winding loader, so not only reduces the waste of blaster fuse frame material, also significantly reduces because of changing the time that lead frame is wasted, reduce production cost, improved productivity.
