Problems solved by technology
The wire break detection device of the traditional multi-wire cutting machine detects the wire breakage through the guide wheel baffle when the metal wire breaks. In one piece, if it cannot be thrown onto the baffle plate, the disconnection alarm cannot be triggered, resulting in the scrapping of the metal wire evacuated parts and the damage of the polyurethane layer of the guide wheel, which will cause great economic losses.

Embodiment Construction
[0019] Please refer to figure 1 , the present embodiment provides a wire breakage detection device 100 for a multi-wire cutting machine, which is used to detect broken cutting wires on the cutting wire net. The U-shaped bar 110 and the fixing plate 120 fixedly connect the U-shaped bar 110 to the casing (not shown) of the multi-wire cutting machine. It is well known in the industry that the guide wheels of the multi-wire cutting machine are used in pairs. As far as one of the guide wheels is concerned, the side of the guide wheel opposite to the other guide wheel is the inner side, and the side away from the other guide wheel is the outer side. The cutting wire net is wound back and forth on the two guide wheels, that is, it is arranged between the inner sides of the two guide wheels for cutting silicon ingots.
[0020] Please refer to figure 2 , the fixing plate 120 is roughly L-shaped, one end is connected to the U-shaped rod 110, the other end is connected to the casing, ...

The invention relates to a line breaking detecting device of a multi-line cutting machine. The line breaking detecting device comprises detecting rods arranged on outer sides below guiding wheels, wherein cutting line nets are wound around the guiding wheels, each detecting rod is arranged on one side of the axis of each guiding wheel in the direction identical with the axis direction of each guiding wheel, the two ends of each detecting rod are both connected with connecting rods, and the connecting rods are connected with a machine shell of the multi-line cutting machine and are connected to the ground through the machine shell. According to the line breaking detecting device of the multi-line cutting machine, the detecting rods with small occupied space are arranged below the guiding rods, small distances can be arranged between the detecting rods and the guiding wheels, the detecting rods can be contacted with a broken line in time, and alarming sensitivity is improved.
Description
technical field [0001] The invention relates to the technical field of cutting equipment in the manufacture of photovoltaic silicon wafers, in particular to a wire break detection device for a multi-wire cutting machine. Background technique [0002] Multi-wire cutting machine cutting technology is a relatively advanced slicing processing technology in the world. Its principle is to use a high-speed moving metal wire to carry mortar to frictionally cut hard and brittle materials such as semiconductors at high speed, so as to achieve the cutting effect. During the whole cutting process, the metal wire is guided by the main wire wheel, the tension wheel, and the wire arranging wheel, and the metal wire is evenly wound on the winding guide wheel. Wire system, a wire cutting net is formed on the main pulley, and hard and brittle materials such as semiconductors to be processed are installed and locked on the cutting table, and the cutting head realizes feeding and cutting throug...
