The liquid pipe for the plating solution tank on the electroplating line

Abstract

The invention discloses a liquid taking pipe for a plating solution tank of a plating line. The liquid taking pipe comprises a pipe body (1) of which two ends are communicated, and is characterized in that a liquid inlet (1.1) at the lower end of the pipe body (1) is provided with an elastic head cap (2) which is raised in an initial state and produces deformation to form a concave structure when the liquid inlet of the lower end of the pipe body (1) stretches to a position at preset depth, the elastic head cap (2) is fixed to the lower end of the pipe body (1) and covers the liquid inlet (1.1), the elastic head cap (2) is provided with a through hole (2.1) which is closed when the elastic head cap (2) is raised and is communicated when the elastic head cap (2) is concave, and a piston (3) which is used for preventing a liquid in the pipe body (1) from flowing back from the liquid inlet (1.1) is arranged in the pipe body (1). The liquid taking pipe is convenient for operator single hand operation, can be operated simply and is specifically used for taking a sample from a plating solution tank of a plating line.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for detection instruments, in particular to a liquid-taking tube for a plating solution tank on an electroplating line. Background technique [0002] During the production process of the electroplating line, the content change of the electroplating solution in the plating solution tank is one of the more important factors affecting the final electroplating effect of the product. Therefore, in the prior art, it is often necessary to arrange inspectors to regularly sample and detect each specific position of the plating bath. The above-mentioned sampling process is to first select a pipette with openings at both ends by the inspector, and then press it with a finger. And seal the upper end of the pipette, and at the same time immerse the lower end of the pipette in the plating solution tank. At this time, the high-pressure air formed in the pipette tube blocks the liquid on the surface o...

[0003] However, the method of pressing with fingers can only be applied to pipettes with small diameters. For pipettes with larger diameters, the method of pressing with fingers cannot be used to complete sampling. At the same time, for women In other words, its fingers are often small, so in the prior art, a general-purpose pipette is used for sampling the electroplating line, which has the disadvantage of a small scope of application.

[0004] In addition, due to the strict detection requirements for the sampling position of the plating bath, for some detection positions that are far away, the inspector needs to stretch one hand to the limit position to place the pipette above the detection position. , the inspector needs to hold the pipette with one hand and simultaneously complete a series of actions such as pressing the finger to seal, releasing the air pressure, pressing the seal again, and then extracting the pipette. The operation difficulty is relatively large
