Problems solved by technology

[0006] In the conventional reciprocating movement control of the touch roller type, since the speed correction control is not performed before the wire material touches a certain touch roller, it can roughly cope with the slight misalignment of the wire material on the reel, but in the part of the reel When the winding pitch of the wire deviates greatly, due to the delay of the control system, the guide roller for reciprocating movement cannot quickly follow the change of the large winding pitch, and sometimes the wire will fall off the guide roller or the wire will break question

Embodiment Construction

[0037] figure 1 The relationship between the reciprocating device 1 and the wire saw 2 to which it is attached is shown. The reciprocating device 1 is provided on the winding side of the wire rod 3 in addition to the feed-out side of the wire rod 3 with respect to the wire saw 2 .

[0038] exist figure 1 In order to supply the wire 3 to the wire saw 2, the wire 3 is wound and stored on the reel 4 on the feed side, and the reciprocating device 1 on the delivery side pulls the wire 3 from the reel 4 and winds it on the reel 4. After the grooved reciprocating roller 5 is on, it is guided in the direction of the wire saw 2 via the grooved tension roller 14, the tension adjustment roller 15, and one or more than two grooved guide rollers 18. The wire saw 2 cuts a workpiece with the advancing wire 3 . Then, the wire 3 is guided to the winding side by one or two or more grooved guide rollers 18, passing through the grooved tension adjustment roller 15, the grooved tension roller 1...

Abstract

The invention provides a traverse control technology, capable of preventing the deviation and broken line of a wire rod in advance with the bigger change of the wire rod reeling spacing. A traverse device (1), reels the wire rod (3) of a reel (4) for a linear saw (2) on a traverse roller (5) and a tension roller (14), when the traverse roller (5) is the reciprocating motion along the axial direction of the reel (4), the target position of the wire rod (3) is in the right-angle direction relative to the axial direction of the reel (4) between the reel (4) and the traverse roller (5), the reference force (F1) of the wire rod (3) is detected at the tensioning roller (14), the variation force (F2) based on the displacement of the wire rod (3) deviated from the target position is detected at the traverse roller (5), based on the variation of the difference (delta F) of the reference force (F1) and the variation force (F2), the reciprocating speed (V) of the traverse roller (5) is controlled.

Description

technical field [0001] The present invention relates to a method and device for controlling the moving speed of a reciprocating roller in a reciprocating device for a wire used in a linear saw. Background technique [0002] In order to supply the wire to the wire saw, the delivery-side reel has the wire in a neatly wound state. Starting from the reel on the sending side, the wire is supplied to the cutting position of the wire saw through the reciprocating device on the sending side, and after cutting workpieces such as semiconductors at the cutting position, it is neatly wound through the reciprocating device on the winding side Wind the wire on the winding side reel. [0003] As shown above, the reciprocating device is provided on both the sending-side reel and the winding-side reel, and by moving the reciprocating roller in the lateral direction with respect to the traveling direction of the wire at positions close to the respective reels, in other words , to reciprocat...
