Abstract

The invention discloses an accurate PEG (polyethylene glycol) liquid pumping device which comprises a vehicle body, a liquid storage tank, a liquid conveying pump and a liquid outgoing pipeline. Traveling wheels are mounted at the bottom of the vehicle body, a controller is mounted on one side of the vehicle body, the liquid storage tank is arranged on the vehicle body, the liquid conveying pump is mounted at the bottom of one end of the liquid storage tank, a liquid outgoing end of the liquid conveying pump is connected with the liquid outgoing pipeline, a flowmeter is arranged on the liquid outgoing pipeline, and the controller is in communication connection with both the flowmeter and the liquid conveying pump. By accurate feedback of the flowmeter and automatic control of the controller, manual intervention in the process of operation can be reduced, multiple pumping vehicles can be operated by one person simultaneously, and working efficiency and metering accuracy are high. The automatic controller can effectively avoid artificial operation errors. In addition, the accurate PEG liquid pumping device is compact in overall structure and convenient in moving on a working site.

Description

technical field [0001] The invention belongs to solar silicon chip cutting technology, in particular to a PEG liquid precision pumping device for auxiliary mortar mixing. Background technique [0002] The mortar used for silicon wafer cutting is a suspension of SiC (silicon carbide) cutting sand and PEG liquid (polyethylene glycol). When mixing mortar, it is necessary to mix silicon carbide and polyethylene glycol in strict accordance with the ratio, otherwise the prepared Mortar cannot meet the requirements of silicon wafer cutting. Generally, a hydraulic forklift with weighing function is used to measure PEG liquid. In this method, the barrel containing PEG liquid is first placed on the weighing forklift and pumped out by a pneumatic diaphragm pump, and then the PEG liquid is determined by manual reading. Pumping volume, after reaching the required volume, manually close the pneumatic diaphragm pump. This method is prone to low accuracy of the pumping volume of PEG liqui...
