The content of the invention
Line hair of the invention in order to solve the real winding part by being constituted through the multilaminate coiled mesa-shaped lamination form of intersection
Raw heap goods avalanche, and completed in the above mentioned problem that closing line of pure silver alloy etc. weares and teares, its object is to provide than existing
There is technology fastening force stronger, and the vibration etc. when will not be because of conveying and the winding structure of the novel closing line of heap goods avalanche.This
Outside, it is an object of the invention to provide a kind of composition by the top that tail end winding part again group is entered to real winding part,
There will not be the waste for the line that can not be used in engagement whereby, the semiconductor device that can also successfully carry out the replacement operation of bobbin is used
The winding structure of closing line.
(means for solving problem)
To achieve the above object of the invention, the present invention proposes the winding structure of closing line, wherein：The front volume wound by sequence
It is wound with and connects on the bobbin that the tail end winding part of the multilaminate coiled real winding part of part, intersection and sequence winding is constituted
Zygonema, at least one side hypotenuse formed in the two ends shape of the real winding part, at least one side hypotenuse have with than
The middle hypotenuse at the more anxious steep elevation angle in the elevation angle of the lower hypotenuse extended by bobbin ends or the jut of upper hypotenuse, in the projection
Portion in succession wave mode zigzag layer, and the summit of the upper hypotenuse height than the zigzag layer average height it is higher.
In the winding structure of the closing line of the present invention, why formed at least in the two ends shape of real winding part
One side hypotenuse, the middle hypotenuse or upper hypotenuse for having the more anxious steep elevation angle in the elevation angle with lower hypotenuse than being extended by bobbin ends
Jut, is the reason for the effect of so-called breakwater is played based on the vibration to transverse direction.Due to the height on the summit of upper hypotenuse
Average height than zigzag layer is higher, therefore the pressing force of the jut of upper hypotenuse is scattered with horizontal direction, can press down whereby
Make the transverse shakiness of the real winding part of the section shape of nearly rectangle.That is, even if the thickness of real winding part is uprised, from tail end volume
Pressing force around the vertical direction of part can't disperse, thus can than existing less jut pressing force, pressing is near
The real winding part of rectangular cross-sectional shape.
In addition, why jut wave mode in succession zigzag layer, be to be applied in order to scattered because of the vibration in conveying
It is added on the drag of the horizontal direction of line.That is, for prevent real winding part through intersecting the reason for multilaminate coiled line unclamps.By
The section triangle that zigzag layer is formed, for the scattered drag for putting on line, if therefore having a certain degree of height i.e.
Can.All height of the height less than the top of upper hypotenuse of the section triangle of zigzag layer can generally be made.Even if in addition, subtracting
The small section triangle, the narrow range on the base equivalent to section triangle has the pressing force of vertical direction, and can
The drag of the scattered horizontal direction for putting on line.In addition, the zigzag layer of the wave mode also has the pressing force of vertical direction, therefore can
Make the pressing force of the vertical direction of the jut of the upper hypotenuse of the drag of horizontal direction to putting on line relatively reduced.
Preferably implement state in the winding structure of the closing line of the present invention as follows.
Preferably described jut is configured to stepped.Reason is the hypotenuse spindle such as fruit winding part, easily
The heap goods avalanche because of transverse shakiness.If jut is configured to stepped, so-called breakwater will become big.Even if therefore real wind
The thickness of partial coating is uprised, and the spiral construction throughout the closing line of total length is not easy to crumble.In addition, the section of jut
Product is preferred more than the average cross-section product of the zigzag layer of the wave mode.It is to play the effect to the breakwater of transverse shakiness.That is,
The height of jut can be increased or widen wide cut.Strengthen supporting the pressing for touching the both ends in the tail end winding part of real winding part
Power, and in order that the line of real winding part will not be slided.In addition, in the other extreme can remove the tail end winding part or
The front winding part, is only constituted winding structure with real winding part.This is in order to save the line of waste.
In addition, being preferably equipped with the jut at the two ends of the real winding part.Even if this with tweezers in order to be pinched
The terminal of closing line is grabbed, is not easy to unclamp.In addition, also for preventing transverse shakiness.
In addition, the quantity at the peak of the zigzag layer of preferably above-mentioned wave mode is provided with 7~18.The peak of zigzag layer is general
Refer to the shape that line repeats triangle.But, actual triangle is not symmetrical, the hypotenuse formed with line
Also it is deformation.Therefore, for convenience, benchmark will be turned among the plane of projection, the line of the jut for the upper hypotenuse that continues
The height of line, the higher situation of the neighbour height for connecing two adjacent lines, is counted as 1 peak.
In addition, preferably described closing line is silver alloy.Not only pure silver alloy, it is as follows the reasons why containing silver alloy.
That is, practical silver alloy, such as Ag-Pd alloys, Ag-Pd-Pt alloys, Ag-Pd-Au alloys, because fusing point is low and matter is soft, because
This easily causes surface abrasion, so the effect of the present invention can play particularly significant.
In addition, preferably described closing line, which is noble metal, is coated to copper alloy.Noble metal is coated to copper alloy wire and also compares gold line
It is easier to cause surface abrasion, and the effect of the present invention can be played.In this, it is coated to copper alloy wire in noble metal and also includes Pd paintings
Apply fine copper alloy wire or Au disperses Pd coating fine copper alloy wires.These easily cause surface abrasion than gold line, and can play
The effect of the present invention.
In addition, the elevation angle of real winding part is more anxious steep, more lines can be wound, but the number of plies such as fruit winding part becomes
Thickness, then can easily crumble.In addition, the peak of zigzag layer is preferably the face of more than half to be formed above the real winding part
Product, is most preferably formed throughout comprehensive.In addition, the number of plies of real winding part or spacing interval are fitted by used engagement device
Work as setting.
(The effect of invention)
By the present invention closing line winding structure, using than prior art as smaller tail end winding part tension force,
It can firmly fix than prior art more elongated closing line, that is, increase the line of the real winding part of Winding Layer.In addition,
The zigzag layer of wave mode is scattered, and the horizontal direction for substantially restraining the line of real winding part is rocked, therefore even for
Vibration during conveying etc., also have more has resistance than prior art, can prevent the vibration than prior art more elongated line from shaking
Shake.Specifically, in the closing line as formed by pure silver alloy or silver alloy, elongated line more than 1 km can be wound securely,
, can be securely as fine copper or copper alloy or in closing line formed by being coated with Pd Cu or copper alloy (above-mentioned " Pd copper coateds ")
Elongated lines more than 2 kms is wound, and in the closing line as formed by proof gold or billon, can be wound securely more than 5 kms
Elongated line.Then, elongated the rocking property of line vibration resistance as implied above wound is strong, and is not worn and torn on the surface of closing line
Deng, therefore stable joining process can be carried out continuously.
In addition, by the present invention, it can be supplied to than prior art more elongated closing line, therefore the rewinding operation of closing line
With less number of times.In addition, the line of tail end winding part can be used on closing line, therefore line will not be wasted, and
