The utility model discloses a bur-removing machine for diode leads, which is a machine used for removing plastic package materials (burs) adhering to plastic package diode leads and straightening the leads. The utility model is characterized in that the diode leads is moved in a planetary mode in a wedge-shaped gap formed by the inner circular cone surface of a skiving cutter body and the outer circular surface of a rubber wheel, and the skiving cutter body is moved in reciprocating mode. The utility model has the advantages of simple structure and low operating expenses; the bur-removing efficiency reaches to ten thousand per hour, and the bur-removing cleaning rate reaches to ninety-nine out of a hundred; the leads have higher surface finish after burs on the leads are removed, and the surface of the plastic package body can keep glossy.
Description
The utility model is one and removes the capsulation material that the plastic package diode lead-in wire upward adheres to, and has the machine of alignment lead-in wire effect.
Existing diode lead (hereinafter to be referred as lead-in wire) is gone up the capsulation material (burr promptly goes between) that adheres to, and relies on manual the removal, or removes with shot-peening with import equipment three-way vibration sieve.The manual removal, production efficiency is low, and wire surface is of poor quality, three-way vibration sieve apparatus costliness, operating cost height.More than two kinds of methods all can not be with the lead-in wire alignment.
The utility model provide one simple in structure, per ten thousand of operating costs are no more than one yuan, deburring efficient reaches per hour 10,000, burr goes clean rate to reach 99 percent, has the diode lead flash trimmer of alignment lead-in wire effect.Lead-in wire after the deburring has higher fineness, and can keep the plastic-sealed body lustrous surface.
Utility model is to realize like this, diode is through the ordering of ordering funnel, send into by drawing-inroller successively, plastic-sealed body is sent in the circumferential groove of rubber wheel middle part, lead-in wire is admitted in the wedge-shaped crevice of rubber wheel outer round surface and scraping cutter hub internal conical surface formation, when rubber wheel counterclockwise rotates, lead-in wire cylindrical and the friction of rubber wheel cylindrical, lead-in wire is done clockwise rotation and the planetary motion of revolution counterclockwise, when the scraping cutter hub when elliptic cam and its fixed guide of effect lower edge of recovering spring move back and forth, the capsulation material that adheres on the diode lead will be repeatedly by scraping, goes between in wedge-shaped crevice through repeatedly rotating, with its spreading alignment.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Accompanying drawing 1 " B-B analyses and observe " and accompanying drawing 2 " A to " are the structural representations of diode lead flash trimmer.
The primary structure and the course of work below in conjunction with accompanying drawing 1 and accompanying drawing 2 detailed description diode lead flash trimmers.
This flash trimmer is divided into two parts, and first is the ordering feed mechanism, and second portion is the scraping aligning mechanism.
In the ordering feed mechanism, diode is sent into forward funnel (2) forward through feed funnel (1), and forward the forward plate (3) of funnel (2) divides two row's inclination 45 degree to install, and makes when diode leans on gravity to descend, and progressively proofreaies and correct to be horizontal direction.In the ordering funnel, it forward is level that diode continues, and radially proper alignment can reached axially, ordering funnel plate (5A) and (6A) between with ordering funnel plate (5B) and (6B) (picture among the figure of the slit (7A) that constitutes, structure respectively with (5A) and (6A) identical) between the slit (7B) that constitutes (draw among the figure, (7A) identical), be used for by lead-in wire (24), promptly as the rail plate that goes between.The size in this slit is 1.5 times of diameter wire.Make the lead-in wire that adheres to capsulation material also can pass through smoothly, (5A) with a side shield (25) that (6A) constitutes plastic-sealed body (26), (5B) with the opposite side baffle plate (27) that (6B) constitutes plastic-sealed body (26), distance between the biside plate is 1.2 times of plastic-sealed body (26) length, moves down to guarantee the plastic-sealed body orientation.The forward plate (8) of ordering funnel plays the level of corrections direction in sequencer procedure, thus (7A) or slit (7B) be not straight line only, be still in order forward to need.Diode arrives the lower end of ordering funnel, and is just side by side horizontal, enters successively in the groove (12) of drawing-inroller (9).Uniform several grooves of the excircle of drawing-inroller (9) (12), in order to determine feeding speed, the degree of depth of groove (12) is the radius and the diameter wire sum of plastic-sealed body (26), the width of groove is that the thickness of drawing-inroller is littler 0.05 millimeter than plastic-sealed body length.The lower end of ordering funnel has with two sections circular arcs (10A) of parts feeding axle (28) concentric and (11A), the little 1.5 times of diameter wire of the radius of the radius ratio drawing-inroller of circular arc (10A), the big 1.2 times of diameter wire of the radius of the radius ratio circular arc (10A) of circular arc (11A), like this, when drawing-inroller (9) when clockwise rotating, fall into the diode in the groove, its lead-in wire (24) will be along (10A) and the circular arc slit (23A) that (11A) constitutes with (10B) (draw among the figure, structure same (10A)) (draw among the figure in the circular arc slit (23B) that constitutes, structure is with (23A)) to send in the wedge-shaped crevice (14) that rubber wheel outer round surface (22) and scraping cutter hub internal conical surface (13) constitute, plastic-sealed body (26) is admitted in the middle part of the rubber wheel in the rectangular channel (21) on the circumference.And the place of the non-groove of drawing-inroller (9), diode lead (24) is higher than circular arc slit (23A) and (23B), and diode (4) can not be admitted to.In the ordering feed mechanism, feed funnel (1), funnel (2) forward, ordering funnel (3) all is fixedly connected with frame (17).
The scraping aligning mechanism is by rubber wheel (15), scraping cutter hub (20), camshaft (16) and recover spring compositions such as (31).Rubber wheel (15) the General Purpose Rubber manufacturing of making seal, the rectangular channel (21) of its middle part circumference, width is that the length of plastic-sealed body (26) adds 0.02 millimeter, groove depth is the diameter sum of the radius and the diode lead (24) of plastic-sealed body (26).Scraping cutter hub (20) is made with the general tool steel, the along the circumferential direction uniform a plurality of shallow slots in scraping cutter hub female cone surface (30), to form a plurality of blades (32), scraping cutter hub female cone surface (13) is the conical surface that tapering is 1:40, the big end of the conical surface is near plastic-sealed body (26), and like this, the slit (14) that makes the conical surface (13) and rubber wheel outer round surface (22) constitute is a wedge shape, wedge-shaped crevice is in the slit minimum at lead-in wire root place, and its value is 0.95 times of diameter wire.When rubber wheel (15) when its axle (29) counterclockwise rotates, the diode lead of sending into wedge-shaped crevice (14) is at first stressed and maximum at root, lead-in wire is done clockwise rotation and the planetary motion of revolution counterclockwise under the effect of rubber wheel frictional force, meanwhile, scraping cutter hub (20A) and (20B) by thereon anti-wearing liner (19) of edge at elliptic cam (16) be installed under the effect of the recovery spring (31) on the frame (17), move back and forth along the fixed guide (18) that is parallel to rubber wheel shaft (29), like this, capsulation material on the diode lead is repeatedly scraped away by blade (32) on whole circumference.Scraping cutter hub female cone arc length should be greater than 10 times of lead-in wire girth, to guarantee lead-in wire energy rotation more than 10 times in wedge-shaped crevice (14), the rotating speed of camshaft (16), in the time of should making lead-in wire (24) through scraping cutter hub female cone arc length, scraping cutter hub (20A) and (20B) reciprocal time be no less than 7 times.The planetary motion of lead-in wire (24) makes lead-in wire through spreading repeatedly and alignment makes diode (4) withdraw from flash trimmer simultaneously.
