Abstract
The present invention provides a manufacturing method for the core column of a shielded needle with a third guiding thread. In the method, a conventional mode that materials are delivered to the head section of the core column by the third guiding thread through a mechanical arm is changed into a mode that the materials are dropped along the inner chamber of an air exhaust pipe and are delivered from a bell mouth towards a part flattened by clamping to a guide thread positioning mechanism. The manufacturing method for the core column of the shielded needle in the present invention overcomes the defects of frequent failure occurrence of the mechanical arm, inconsistent length of delivered threads, etc. of a traditional material delivery device, and non defective rate of the shielded needle is improved. In addition, the present invention also has the advantages of simple devices and convenient operation, and the manufacturing method for the core column of the shielded needle in the present invention is beyond the limitation of the dimensions of a lamp tube.
Description
Branch art field the present invention relates to a kind of method for making of fluorescent lamp wick column, particularly relates to a kind of method for making with three seal wire stem stems of shielding needle.
The existing fluorescent lamp of technical background often is provided with shielding needle (as German fluorescent tube) or shading ring (as the Philip fluorescent tube) in order to prevent early stage yellow deceiving with prolonging lamp tube service life on stem stem, the support bar of this shielding needle and shading ring all is one the 3rd seal wire of setting up in two seal wire central authorities of original stem stem.
In fact the method for making of shielding needle stem stem is exactly the method to set up of this 3rd seal wire.From the fluorescent lamp production line of Britain Bei Telai company introduction, setting up an organization of this 3rd seal wire just arranged.It is to drive cam by main shaft to promote the slide block feeding through several connecting rods.Fit tolerance between the connecting rod, between slide block and the guide rail must be controlled very strictly, size has deviation slightly, the short partially phenomenon of the ineffective or inclined to one side length of action in the time of will occurring sending the 3rd seal wire, the lighter's stem stem great wheel sky, influence output, it is firm or extend to steam vent (real core stem stem is to penetrate the flat part of folder) and cause the stem stem waste product that the wrapping of the 3rd seal wire appears in heavy person.Facts have proved, spend in and adjust the time of the 3rd seal wire on setting up an organization more than 85% of button stem machine maintenance time that accounts for that usually cause stem stem under-supply thus, influence is produced and raw material are wasted greatly completely.
Many producers improve at the problem that early stage, equipment existed, and have manufactured and designed one the 3rd seal wire with regard to oneself such as Guangzhou Light Bulb Factory and have set up an organization and replace the equipment of Britain Bei Telai company.But the 3rd seal wire does not change by the pattern of finger feed to the button stem machine chieftain, still can't be eradicated by the disadvantage that this feeding pattern of the 3rd seal wire causes.
Summary of the invention
The new technology that the objective of the invention is to provide a kind of the 3rd seal wire to be provided with, its can simplified apparatus, handled easily, wire feed are accurate, and the percent defective that causes because of the 3rd seal wire levels off to zero.
The object of the present invention is achieved like this: the feed funnel that one the 3rd seal wire is set above blast pipe; The 3rd seal wire is sent by funnel, falls into to the flat direction of folder along the blast pipe inner chamber from horn mouth; There is the detent mechanism (this mechanism can with the detent mechanism processing of original two seal wires together) of one the 3rd seal wire the below that loudspeaker press from both sides flat part.
The present invention only needs the feeding pattern of the 3rd seal wire is delivered to the stem stem head by manipulator and changed the guide effect that utilizes blast pipe into and allow the 3rd seal wire fall into the seal wire detent mechanism like clockwork from original.Design processing by the seal wire detent mechanism can allow the 3rd seal wire strictness put in place and locks length.Phenomenons such as manipulator behavior is malfunctioning, the not firm or inclined to one side length of seal wire wrapping is short have partially so just been avoided.
Description of drawings
The present invention does an into explanation by following embodiment and accompanying drawing.
Accompanying drawing is the method for making schematic flow sheet of the T5 fluorescent lamp shielding needle stem stem relevant with the present invention, and 1 is the feed funnel of the 3rd seal wire among the figure, and 2 is blast pipe, arrow 3 expression wire feed directions, and 4 is loudspeaker, the 5th, the seal wire detent mechanism.
Embodiment
The 3rd seal wire by prior making regularly falls into feed funnel, and hopper outlet aligns with blast pipe is suitable for reading; The 3rd seal wire falls into seal wire detent mechanism by horn mouth towards the flat part of folder through the blast pipe guiding; The 3rd seal wire is pressed from both sides flat part length of wrapping up and the size that stretches into fluorescent tube to be determined by detent mechanism fully.
The T5 series fluorescent lamp that utilizes the shielding needle stem stem production that method of the present invention makes is lit a lamp to test and life-cycle through on-off ratio and has more all been embodied the due technical advantage of shielding needle fluorescent tube.
What deserves to be mentioned is that the fluorescent lamp tubuleization is a development trend, the shading ring stem stem will cause the quality shade of tubule, and the shielding needle fluorescent tube of German pattern is comparatively desirable.But along with the refinement stem stem of fluorescent tube will be more small, one the 3rd seal wire is set again, will be difficult to conduct for existing wire feed manipulator, and the method for making of shielding needle stem stem of the present invention not be subjected to the restriction of fluorescent tube size in two seal wire central authorities of several millimeters of spacings.
Claims (1)
1. method for making that is used for the shielding needle stem stem with the 3rd seal wire of fluorescent lamp, it is characterized in that: the 3rd seal wire is along blast pipe inner chamber blanking; There is a feed funnel blast pipe top; There is the detent mechanism of one the 3rd seal wire the blast pipe below.
