A high-precision washing head

Abstract

The invention discloses a high-precision plate washer, relates to the technical field of the plate washer, and specifically includes a support mechanism, a connecting device and a plate washer needle assembly. The front and rear sides of the support mechanism are equipped with connecting devices. The plate washing needle assembly vertically runs through the inside of the support mechanism, and the plate washing needle assembly includes a first gas injection cylinder, a second gas injection cylinder, a third gas injection cylinder, a communication pipe, a liquid injection pipe, an air connection pipe, a rubber folding cylinder, a cone cover, bristles and needle tube, the first gas injection cylinder, the second gas injection cylinder and the third gas injection cylinder are connected in sequence along the vertical direction, the top of the first gas injection cylinder is welded with a liquid injection pipe, and the third gas injection cylinder The bottom end of the injection tube is bonded with a rubber folding tube, and the bottom end of the liquid injection tube is connected with a needle tube. The high-precision washing head can independently control the expansion and contraction of each washing needle through the principle of air pressure, and the amount of expansion and contraction of each washing needle depends entirely on the amount of air drawn out or filled in, so the precision is relatively high. high.

Description

technical field [0001] The invention relates to the technical field of washing head, in particular to a high-precision washing head. Background technique [0002] The development of plate washer can be roughly divided into three stages, simple type, automatic type, and integrated environment type plate washer. The simple type washer can also be called manual plate washer, which generally consists of a negative pressure pump and a cleaning head. Complete the most basic liquid absorption, the automatic plate washer can complete the plate washing work for the specified number of times and strips according to the user’s settings, and the integrated environment plate washer can provide a good plate washing environment and has certain intelligent features. [0003] The plate washer head is an important structure on the plate washer. Generally, there are multiple plate washer needles on the plate washer head, and the plate washer water is injected into the plate washer, and the enz...

Problems solved by technology

[0004] In the actual use of the existing plate washing head, each plate washing needle cannot achieve independent telescopic movement, which leads to low precision and poor cleaning effect when cleaning the microplate plate, and it is difficult to adjust the cleaning efficiency. For improvement, the washer head considers the firmness of the structure, and the washer needles inside are mostly fixed installations. This kind of structural setting brings more impossibility to the telescopic movement of the washer needles.
