In the working state, when the mirror oil in the oil storage container 1 is detected to be exhausted: the first electromagnetic valve 101 switches the second oil pipe 22 to be communicated with the fourth oil pipe 24, and the driving part 4 sucks the mirror oil in the buffer container 10; after the oil absorption is finished, the second electromagnetic valve 102 switches the third oil pipe 23 to be communicated with the fifth oil pipe 25, and the driving part 4 drops the absorbed mirror oil onto the glass to be detected through the oil dropping needle 3.

The arrangement of the buffer container 10 enables the mirror oil in the oil storage container 1 to still maintain a normal working state after being used up, and in the process of buffering oil dripping of the buffer container 10, the oil storage container 1 is replaced or the oil storage container 1 is filled up, so that continuous working can be realized, and the detection efficiency is improved.

The oil dripping device 100 further comprises a detector 103, the detector 103 is installed on the first oil pipe 21, the detector 103 is a sensor such as an optical coupler and hydraulic pressure, when no mirror oil exists in the oil storage container 1, gas can be sucked from the oil storage container 1 in the first oil pipe 21, at the moment, information such as pressure and optics of the first oil pipe 21 can be different, and according to the difference information, the detector 103 can detect out the mirror oil existing in the oil storage container 1. When the detector 103 detects that no mirror oil exists in the oil storage container 1, a buffer trigger signal is formed, and the buffer trigger signal is used for triggering the oil dripping buffer liquid circuit to be switched to the buffer container 10 for oil supply.

Install the oil mass detector in the oil storage container 1, whether the mirror oil that the oil mass detector can detect in the oil storage container 1 equally exhausts, when the oil mass detector detects no mirror oil in the oil storage container 1, mirror oil in the driving piece 4 absorption buffer container 10 to on filling the glass piece that awaits measuring through oil dripping needle 3 with the mirror oil of absorbing.

Buffer container 10 still is equipped with and examines empty device and bleeder vent, examines empty device and is used for detecting whether buffer mirror oil in buffer container 10 exhausts, examines empty device's setting and can realize automatic replenishing oil for buffer container 10, also can remind doctor manual control replenishing oil. The buffer container 10 is installed upside down, and the air holes are formed in the upper end of the buffer container 10, so that oil discharge and oil supplement of the buffer container 10 are facilitated.

When the buffer container 10 is replenished with oil, the driver 4 is also controlled to fill the first oil pipe 21 with the mirror oil and discharge the air in the first oil pipe 21, so that the oil dropping operation can be performed immediately after the oil storage container 1 is replaced.

It is right to have used specific individual example above the utility model discloses expound, only be used for helping to understand the utility model discloses, not be used for the restriction the utility model discloses. To the technical field of the utility model technical personnel, the foundation the utility model discloses an idea can also be made a plurality of simple deductions, warp or replacement.
