Abstract
The invention discloses an automatic tabulating device for punching and forming a lead frame with a material tube expansion mechanism. A material tube expansion mechanism is arranged on an automatic tabulating device for punching and forming a lead frame. The material tube expansion mechanism comprises an open type holding cavity [7] matched with a material tube in size as well as an expansion plate [5] and a push rod [6] arranged in the holding cavity [7]. The holding cavity [7] is arranged at the end parts of a guide rail [4] and an cover plate [3] of the automatic tabulating device; an empty cavity connected with the holding cavity [7] is arranged on the guide rail [4]; the push rod [6] is arranged in the empty cavity; the upper end of the push rod [6] is arranged in the holding cavity [7]; and the expansion plate [5] is conically fixed in the bottom part of the holding cavity [7]. The automatic tabulating device for punching and forming the lead frame with the material tube expansion mechanism realizes automatization; products can be smoothly fed into tubes; the device stability is greatly improved; no damages are caused to the lead pins of the products; and the product quality is stable. Moreover, the automatic tabulating device for punching and forming the lead frame with the material tube expansion mechanism is convenient to operate and maintain and has low working intensity.
Description
Technical field
The present invention relates to the automatic tubulature device of lead frame punching molding, especially the material enlargement of pipe mechanism of the automatic tubulature device of lead frame punching molding.
Background technology
At present, IC is manufactured industry in rear operation automatic cutting former, generally after punching molding, must realize automatic tubulature to part plastic packaging lead frame, as shown in Figure 1 and Figure 2, also more and more higher to the stability requirement of equipment.Material pipe is generally PVC plastic material, is to extrude continuously drawing moulding by mould, then cuts apart the material pipe 1 that cuts into certain length.Exist portion's sub-feed tube to occur depressed deformation at the material mouth of pipe, as shown in Figure 3, H becomes large B and diminishes, and makes plastic-sealed body goods 2 enter pipe and is obstructed, and has a strong impact on the stability of automatic equipment.At present, in rear operation automatic cutting former, realize automatic tubulature adopt as shown in Figure 4, Figure 5 enter pipe mode.This enter pipe mode to material pipe quality requirements high.Size B according to different plastic-sealed body goods 2 mostly between 0.15mm～0.5mm.The material of material receiving pipe and the restriction of production technology are difficult to ensure that the H value of every material pipe is all less than B value.Sometimes have to be out of shape material pipe by manual sorting in order to improve the stability of equipment.At the bottom of so just there is human factor impact, stabilization of equipment performance, the shortcoming such as production capacity is low, labour intensity is large.
Summary of the invention
Object of the present invention is exactly to solve the distortion due to material pipe in the time of tubulature of the automatic tubulature device of lead frame punching molding, makes production capacity low, the problem that labour intensity is large.
The technical solution used in the present invention is: the automatic tubulature device of lead frame punching molding of Dai Liao enlargement of pipe mechanism, it is characterized in that it is on the automatic tubulature device of lead frame punching molding, to be provided with material enlargement of pipe mechanism, described material enlargement of pipe mechanism comprises open cavity volume, is positioned at the push rod of the expanding plate of cavity volume, described cavity volume is positioned at guide rail and the patch ends of automatic tubulature device, described guide rail is provided with the cavity being connected with cavity volume, push rod is positioned at cavity, upper end is positioned at cavity volume, the tapered bottom that is fixed on cavity volume one side of described expanding plate.
Adopt technique scheme, material pipe is in the first directly insertion of when filling with substance cavity volume, and the expanding plate in cavity volume is expanded the entrance to real pipe, and when after material after dress, push rod promotes to expect that pipe exits cavity volume, thus the problem that the distortion of solution material pipe causes.
For the better expansion that realizes material pipe, above-mentioned expanding plate is two, is separately fixed on the upper wall and lower wall of cavity volume.
Better exit effect for reaching material pipe, cavity and push rod respectively have two, lay respectively at the both sides of cavity volume bottom.
The invention has the beneficial effects as follows: adopt first sky material pipe is advanced to semi open model cavity volume, then the full material pipe of filling plastic-sealed body goods is exited to cavity volume by push rod, utilize this one-in-and-one-out of material pipe and the guide effect of material enlargement of pipe sheet to make the material tube inlet place spreading of expecting mouth of pipe distortion to approaching perfect condition, plastic-sealed body goods enter to manage smooth and easy.Material enlargement of pipe sheet and plastic-sealed body goods enter to manage non-interference, simple in structure, can adapt to expect that the PVC material pipe that the mouth of pipe is out of shape within the specific limits uses on integrated circuit automatic cutting former, realize automation, goods enter to manage smooth and easy, greatly improve the stability of equipment, the terminal pin of product is not damaged to product with stable quality; Convenient operating maintenance, labour intensity is little.
