Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] see figure 1 As shown, a horizontal take-up and pay-off wire tension control mechanism includes a base plate 1 and a steel wire 13. The wire tension measuring guide wheel 5, the pay-off and arranging wire control guide wheel 6 control the tension on the pay-off side; The wire arranging guide wheel 10 and the take-up roller 9 control the tension of the take-up side; the limit post 7 is fixedly connected to both sides of the tension control guide wheel 12 and the wire-releasing control guide 6; the anti-rotation block 8 is fixedly connected to the On the base plate 1, it is located at the upper left of the pay-off roller 2 and the take-up roller 9.

[0024] Further, see figure 2 As shown, the take-up roller 9 is supported on the shaft 27 by the cone heads 14 at two places on the left and right, and is axially positioned by t...

Abstract

The invention discloses a horizontal type pay-off and take-up tension control mechanism composed of a baseboard and steel wires. The pay-off side tension of the steel wires is controlled through a pay-off roller, a long guide wheel, a pay-off displacing and guide wheel, a pay-off tension measuring guide wheel and a pay-off and displacing control guide wheel; the take-up side tension of the steel wires is controlled through a take-up tension control guide wheel, a take-up tension measuring guide wheel, a take-up and displacing guide wheel and a take-up roller after led out from a cutting chamber; limiting columns are fixedly connected to two sides of the tension control guide wheel and the pay-off and displacing control guide wheel; and rotation preventing blocks are fixedly connected to the baseboard and on the upper left sides of the pay-off roller and the take-up roller. According to the horizontal type pay-off and take-up tension control mechanism, servo-driving is adopted to control the steel wire tension, therefore accurate control of the steel wire tension at a high speed is achieved; independent pay-off and take-up displacement structures are adopted, therefore flexibility of the process is improved; and spatial arrangement of wire rollers is simplified, and wire breaking probability is reduced.

Description

technical field [0001] The invention belongs to the field of multi-wire cutting machines, and in particular relates to a horizontal tension control mechanism for retracting and unwinding wires. Background technique [0002] Multi-wire cutting technology is a relatively advanced silicon wafer processing technology in the world at present. Its principle is to use a high-speed moving steel wire to drive the cutting blade attached to the steel wire to rub against hard and brittle materials such as semiconductors, so as to achieve the cutting effect. . During the whole process, the steel wire is guided by more than a dozen guide pulleys to form a wire net on the main wire roller, and the workpiece to be processed is fed through the rise and fall of the worktable, which can process hard and brittle materials such as semiconductors at one time. Cutting into hundreds of pieces at the same time, compared with other technologies, multi-wire cutting technology has the advantages of hi...
