Abstract
The utility model relates to a work fixture for welding and pickling axial diodes; the work fixture comprises an upper mould and a lower mold; the innovation of the work fixture lies in that a plurality of cavities containing leading wires, chips and soldering lugs are uniformly arranged on the upper end surface of the lower mold; and a pickling tank is arranged on the lower end surface of the upper mold, and cavities which correspond to the cavities of the lower mold and can contain the leading wires are uniformly arranged on the bottom of the pickling tank. When welding is carried out, firstly the welding lugs and the chips are placed in the lower mold filled with the leading wires, the upper mold and the lower mold are assembled, then are welded and formed through the high temperature of a tunnel-based drying oven; and after the welding is finished, the upper mold and the lower mold are entirely overturned so that the upper mold is positioned at the lower part, and the lower mold is positioned at the upper part, thereby the lower mold can be taken down for pickling, and the conversion procedure is reduced, the production efficiency is improved, and the damage of the leading wires caused by conversion is avoided.
Description
Technical field
The utility model relates to a kind of diode and makes frock, the dual-purpose frock of particularly a kind of axial diode welding pickling.
Background technology
The diode manufacturing process flow process mainly comprises welding, pickling, mold pressing, lettering, machine bag, several operation such as inspection and packing outward.When welding successively during operation with pickling; Be applied to two kinds of frocks respectively; Be respectively graphite jig and pickling dish, graphite jig is made up of the identical upper die and lower die of structure, and the surface of upper and lower mould evenly is provided with some die cavities that hold lead-in wire and chip; The pickling panel surface is provided with descaling bath, is evenly distributed with some die cavities that hold lead-in wire at the bottom of the descaling bath.
Adopt the graphite jig of said structure and the shortcoming of pickling dish to be: after welding is accomplished; Need take away patrix, the diode semi-finished product on the counterdie are converted in the pickling dish can carry out pickling, conversion efficiency is low; And be prone to problems such as lead-in wire bending, cause half-finished scrapping.
Summary of the invention
The technical problem that the utility model will solve provides the dual-purpose frock of a kind of axial diode welding pickling, can be applicable to welding and pickling process simultaneously, need not to carry out the conversion of frock, increases work efficiency.
For solving the problems of the technologies described above, the technical scheme of the utility model is: the dual-purpose frock of a kind of axial diode welding pickling, comprise upper die and lower die, and its innovative point is: said counterdie upper surface evenly is provided with some die cavities that hold lead-in wire and chip, weld tabs; Said patrix lower surface is provided with descaling bath, and it is corresponding and can hold the die cavity of lead-in wire that the bottom land of said descaling bath evenly is provided with die cavity with counterdie.
Further, be provided with alignment pin around the upper surface of said counterdie, be provided with the location hole corresponding around the lower surface of said patrix with alignment pin.
The advantage of the utility model is: when welding, at first need weld tabs, chip be placed in the counterdie that fills lead-in wire, with passing through the moulding of tunnel type baking oven high-temperature soldering behind the upper and lower mould matched moulds; After accomplishing welding, the upper and lower mould of whole upset makes patrix following, and counterdie is last, and can take off counterdie carries out pickling, reduces the conversion operation, has improved production efficiency greatly, causes the damage of lead-in wire when avoiding changing simultaneously.

Embodiment
Like Fig. 1,2, shown in 3, counterdie 1 upper surface evenly is provided with some die cavities 11 that hold lead-in wire and chip, weld tabs, around counterdie 1 upper surface, is provided with alignment pin 12.
Like Fig. 4,5, shown in 6, patrix 2 lower surfaces are provided with descaling bath 23, and the bottom land of descaling bath 23 evenly is provided with corresponding with the die cavity of counterdie 11 and can holds the die cavity 21 of lead-in wire.Around the lower surface of patrix, be provided with the location hole 22 corresponding with alignment pin 12.
When welding, weld tabs, chip are placed in the counterdie 1 that fills lead-in wire, patrix 2, counterdie 1 are realized accurate matched moulds through location hole 22 and alignment pin 12, pass through the moulding of tunnel type baking oven high-temperature soldering behind the matched moulds; After accomplishing welding, whole upset patrix 2, counterdie 1 make patrix 2 following, and counterdie 1 is last, and taking off counterdie 1 carries out pickling, reduces the conversion operation, has improved production efficiency greatly, causes the damage of lead-in wire when avoiding changing simultaneously.
Claims (2)
1. the dual-purpose frock of axial diode welding pickling comprises upper die and lower die, it is characterized in that: said counterdie upper surface evenly is provided with some die cavities that hold lead-in wire and chip, weld tabs; Said patrix lower surface is provided with descaling bath, and it is corresponding and can hold the die cavity of lead-in wire that the bottom land of said descaling bath evenly is provided with die cavity with counterdie.
2. the dual-purpose frock of axial diode welding pickling according to claim 1 is characterized in that: be provided with alignment pin around the upper surface of said counterdie, be provided with the location hole corresponding with alignment pin around the lower surface of said patrix.
