Embodiment Construction

[0011] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0012] As shown in Fig. 1, the disconnection protection device for slicing equipment according to the present invention includes an integrally formed double-layer metal plate 1, a double-layer fixing bracket 2 for fixing the metal plate 1 and an alarm shutdown device 6, and the metal plate 1 Located above the guide wheel 4, there are a plurality of small holes for the mortar to leak through. The fixed bracket 2 is connected to the metal plate 1. The surface of the fixed bracket 2 is provided with an insulating shield 5. One end of the alarm stop device 6 is connected to the metal plate 1. Board 1 is connected and the other end is connected to ground.

[0013] When the DS series slicer of MB Company is used to cut silicon wafers, when the steel wire 3 breaks during the cutting process, the broken steel wire 3 loosely touches the metal plate 1 on...

Abstract

The invention discloses a breakage protective device for slicing equipment, which comprises a metal plate, a fixing support and an alarming stopping device. The fixing support is used for fixing the metal plate, the metal plate is disposed above a guide wheel, the fixing support is connected with the metal plate, one end of the alarming stopping device is connected with the fixing support, and the other end of the alarming stopping device is grounded. The breakage protective device has the advantages that when broken, a steel wire contacts with the metal plate, simultaneously, the alarming stopping device can be triggered, accordingly, a machine stops running, effects of protecting the guide wheel and saving silicon materials are realized, economical loss is reduced, and yield is increased advantageously.

Description

technical field [0001] The invention relates to the technical field of cutting equipment in solar cell production, in particular to a disconnection protection device for slicing equipment. Background technique [0002] The shortage of energy makes the development and utilization of solar energy receive more and more attention. The manufacturing process of solar-grade silicon wafers is a hot research topic at home and abroad. For photovoltaic cells based on silicon wafers, crystalline silicon raw material and cutting costs account for the largest part of the total cost of the cell. At present, when the solar silicon wafer cutting equipment is cutting, the hard-point disconnection often occurs, which often causes damage to the guide wheel and waste of silicon materials, which not only brings great economic losses, but also affects the improvement of the production yield of the enterprise. Big trouble. Contents of the invention [0003] Object of the invention: The object o...
