Chip flushing device

Abstract

The invention discloses a chip flushing device which comprises an outer frame body and a flush tank; the outer frame body is provided with an inner cavity used for containing the flush tank, and the flush tank is arranged to be capable of entering or exiting from the inner cavity of the outer frame body; a flushing platform is arranged in the flush tank, and the top of the flushing platform is used for loading a chip; nozzles are arranged at the top of the outer frame body and comprise a liquid nozzle used for spraying flushing liquid to the surface of the chip and a gas nozzle used for blowing gas to the surface of the chip; and the flush tank or the nozzles are provided with a position adjusting mechanism capable of driving the flush tank or the nozzles to move, and the position adjusting mechanism is used for adjusting the relative position of the nozzles and the flushing platform. The flushing device can flush all sites of the chip at the same time, it is guaranteed that actual flushing parameters of all the sites are consistent, the flushing effect of each time is the same, and the flushing device is reasonable in structural design, easy to operate and control, high in working efficiency and capable of effectively saving flushing liquid and gas.

Description

technical field [0001] The invention relates to the technical field of chip washing equipment, in particular to a device for washing electrochemical analysis chips, biological detection chips, modified electrode chips and other chips. Background technique [0002] An electrochemical chip generally consists of a substrate and electrodes on it. The substrate is generally non-conductive glass, ceramics, plastics and other materials, and the electrodes on it are generally metal coatings. There are generally three areas on the electrochemical chip, electrode area, wire area and lead area. When in use, drop the liquid to be tested on the electrode area, and use the contact plate on the connector and chip lead area to derive the signal. [0003] An electrode area on a chip is generally composed of 2-4 electrodes, which is called a cell. In order to achieve high-throughput electrochemical analysis, multiple cells are often placed on an electrochemical chip, and each cell operates ...

AI Technical Summary

Problems solved by technology

Manual operation is difficult to flush all sites at the same time, the actual parameters of each site flushing are inconsistent, and the effect of each flushing is also different

In addition, manual flushing also has disadvantages such as long operation time, low efficiency, and large amount of flushing fluid and gas consumed.

[0009] The other is immersion rinsing, which usually immerses chips or a batch of chips in the rinsing solution to achieve rinsing. Its disadvantage is that it is difficult to ensure that no contamination occurs during rinsing. Moreover, immersion rinsing is also difficult to rinse all positions at the same time. point, the actual parameters of flushing at each point are inconsistent, and the effect of each flushing cannot be guaranteed to be the same

[0010] The other is the automatic washing and drying mechanism disclosed in CN 206139560 U, CN 208146533 U, etc. When this type of mechanism is washing and drying the chip, the water flow and the air flow flow through the surface of the modified electrode, and the modified molecules attached to the electrode surface It has a certain destructive effect, and there is no design to prevent waste liquid from flowing through other sites. It is difficult to ensure that no pollution occurs during flushing, and it is difficult to ensure that all sites on the chip have the same flushing effect
