High-precision plate washing head

Abstract

The invention discloses a high-precision plate washing head, and relates to the technical field of plate washing heads. The head specifically comprises a supporting mechanism, connecting devices and aplate washing needle assembly, wherein the connecting devices are mounted on the front side and the rear side of the supporting mechanism, the interior of the supporting mechanism is vertically provided with the plate washing needle assembly in a penetration mode, the plate washing needle assembly comprises a first gas injection cylinder, a second gas injection cylinder, a third gas injection cylinder, a communicating pipe, a liquid injection pipe, a gas receiving pipe, a rubber folding cylinder, a taper sleeve, bristles and a needle pipe, the first gas injection cylinder, the second gas injection cylinder, and the third gas injection cylinder are sequentially connected in the vertical direction, the liquid injection pipe is welded to the top end of the first gas injection cylinder, the rubber folding cylinder is bonded to the bottom end of the third gas injection cylinder, and the bottom end of the liquid injection pipe communicates with the needle pipe. According to the high-precision plate washing head, stretching-out and drawing-back of all plate washing needles can be independently controlled through a gas pressure principle, and the stretching-out and drawing-back amount ofeach plate washing needle is completely dependent on the amount of gas exhausted or injected, so that the precision is 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...

AI Technical Summary

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.
