Abstract

The invention discloses a device for detecting a deposition rate of mortar. The device comprises a measurement barrel, an infrared detector and a driving device, wherein the driving device is connected with the infrared detector in a driving manner; the infrared detector can translate up and down; the infrared detector and the driving device are connected with a central processor; the infrared detector comprises an infrared emitting end and an infrared receiving end; the infrared emitting end and the infrared receiving end are positioned on the same horizontal plane, and a distance between the infrared emitting end and the infrared receiving end is not smaller than the outer diameter of the measurement barrel. According to the device for detecting the deposition rate of the mortar, the infrared detector is used for detecting and recording a boundary surface of a deposition layer and a supernatant liquid layer of cutting liquid, so that automatic detection is realized; the detection stability is improved, the labor cost is reduced; recording mistakes caused by a fact that a measurer awaits to detect the deposition rate for a long time are avoided.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a device for detecting the deposition rate of mortar in cutting fluid. Background technique [0002] The cutting of silicon material wafers in the photovoltaic industry adopts multi-wire cutting technology. The principle is: the ultra-fine cutting steel wire runs at high speed, driving the mortar (that is, cutting fluid) made of silicon carbide cutting edge and polyethylene glycol attached to the steel wire, so that the silicon carbide cutting edge is pressed tightly on the silicon block to be cut On the surface, under the high-speed operation of the steel wire, the hard characteristics and sharp water chestnuts of the silicon carbide particles grind the surface of the silicon block, thereby gradually cutting off the entire silicon rod. [0003] At present, most of the water-soluble cutting fluids widely used in the market are mainly composed of polyethylene glycol (PEG), and other ...
