Description

Axial diode die assembly

Technical Field

The utility model relates to a diode processing field especially relates to axial diode compound die subassembly.

Background

In the assembly process of the axial diode, a process of die assembly of a lead, a soldering lug and a chip is carried out, namely, the lead of an upper die of the diode is reversely buckled at the other end of the chip, so that the assembly of five raw materials of a lower lead, a lower soldering lug, a chip, an upper soldering lug and an upper lead is realized; then, the tail end of the upper die lead is lightly pressed through the acrylic plate, so that the upper die lead is tightly attached to other raw materials, and the phenomenon of welding breakage can be effectively avoided in the welding process of the raw materials.

However, due to an error in the accuracy of the lead manufacturing equipment, the lead length varies, or an abnormality such as a burr occurs during conveyance after the lead is loaded, which causes a variation in the length of the upper mold lead after the mold is closed, as shown in fig. 3 (the intermediate upper lead 3 is short and cannot contact the acrylic plate). In the process of lightly pressing the lead wire by the acrylic plate, the lead wire is uneven, so that the lead wire can only contact the lead wire with a longer length, and the part of the lead wire is tightly attached to other raw materials. And the lead with shorter length is tightly attached to other raw materials due to no external force, and finally the phenomenon of welding material breakage can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a to above problem, a simple structure is provided, makes each lead wire all can closely laminate the axial diode compound die subassembly of other raw materials at the compound die in-process.

The technical scheme of the utility model is that: the graphite boat comprises a boat body and an acrylic plate, wherein the graphite boat and the acrylic plate are vertically symmetrical, stand columns are respectively arranged at two ends of the boat body, stepped through holes are uniformly distributed in the boat body, the through holes of the pair of boat bodies are communicated, the upper boat body through hole is used for placing an upper lead, and the lower boat body through hole is used for placing a lower lead and a chip;

the acrylic plate is connected between the pair of upright posts of the upper ship body in a sliding mode, containing grooves are uniformly formed in the bottom face of the acrylic plate and correspond to the through holes one to one, and pressing sheets connected through springs are arranged in the containing grooves.

The inner side of the upright post is provided with an L-shaped guide rail, two ends of the acrylic plate are respectively provided with a guide ring, and the vertical section of the guide rail is positioned in the guide rings.

The bottom surface of the pressing sheet is provided with a positioning cylinder.

In the work of the utility model, the lower lead, the lower soldering lug, the chip, the upper soldering lug and the upper lead are placed in the through hole communicated with the upper and lower ship bodies, and the upper lead is pressed down through the acrylic plate; because the bottom surface of the acrylic plate is provided with the containing groove, the containing groove is internally provided with the pressing sheet connected through the spring, and the upper lead wire is contacted through the pressing sheet; because the length of the upper lead is different, the shape of the acrylic plate is adjusted through the elasticity of the spring, and therefore each lead can receive the flapping pressure.

The utility model discloses can greatly reduce the disconnected material proportion of axial product welding spare, improve product welding quality, solve the disconnected material problem of axial product in welding process effectively.
