Abstract
The utility model discloses a nickel tank automatic controller capable of surface processing chemical nickel gold production line, which comprises a sampling pump connected with a nickel tank and an automatic analyzing/feeding/controlling unit of nickel tank liquid medicine, wherein an air exhaust device is arranged between the sampling pump and the automatic analyzing/feeding/controlling unit of nickel tank liquid medicine. By virtue of the air exhaust device arranged between the original sampling pump and the automatic analyzing/feeding/controlling unit of nickel tank liquid medicine, the air extracted by the sampling pump from the liquid medicine is exhausted and prevented from entering the automatic analyzing/feeding/controlling unit of liquid medicine along with the liquid medicine, so as to avoid the following possibilities: the entry of the air influences the stability of liquid medicine concentration analysis, the liquid medicine concentration is unstable and exceeds process range, the nickel tank damage and overturn are caused, and the skip coating and diffusion coating appear on the circuit board undergoing chemical nickel gold surface processing.
Description
Technical field
The utility model relates to the production line of printed circuit board (PCB), specifically is meant the improvement of the nickel cylinder self-actuated controller of a surface treatment chemical nickel and gold production line.
Background technology
For surface mounted welding performance and the anti-extraneous oxidation affects that improves circuit board, prolong the holding time of circuit board, generally need to select circuit board is carried out the chemical nickel and gold surface treatment, circuit board is handled line through chemical nickel and gold, make after chemical reaction deposition one deck nickel on the copper face of circuit board, on nickel, deposit one deck gold then, existing nickel cylinder all adopts self-actuated controller to control, generally with the concentration of the principle analysis liquid medicine of optical absorbance, owing to there is gas to exist in the liquid medicine, the result of interference analysis, the concentration instability that causes liquid medicine to analyze easily, the reactive activity of the de-stabilising effect nickel cylinder of liquid medicine easily causes the plating leakage of wiring board, plating causes scrapping of wiring board.
The utility model content
The problem that the utility model need solve provides a kind of, accurately nickel cylinder self-actuated controller more stable to the concentration analysis of liquid medicine of realizing.
To achieve these goals, the utility model is designed a kind of nickel cylinder self-actuated controller of surface treatment chemical nickel and gold production line, comprise that the sampling pump and the nickel cylinder liquid medicine that are connected with the nickel cylinder analyzes the interpolation control module automatically, analyze automatically to add between the control module at sampling pump and nickel cylinder liquid medicine and be provided with the emptying device of air.After local time liquid medicine extracted and enters the emptying device of air, gas can float, and only liquid medicine enters nickel cylinder liquid medicine by pipeline and analyzes the interpolation control module automatically, and the analysis of liquid medicine is just more stable.
Described emptying device of air comprises that the container of sealing is arranged at feed tube, drain pipe and the gas outlet on the container, and feed tube is connected with sampling pump, and drain pipe is analyzed the interpolation control module automatically with nickel cylinder liquid medicine and is connected, and gas outlet is provided with valve.
The improvement of the nickel cylinder self-actuated controller structure of the utility model surface treatment chemical nickel and gold production line has the following advantages:
1, nickel cylinder liquid medicine adopts to analyze automatically and adds the liquid medicine control module, helps liquid medicine control;
2, between original sampling pump and nickel cylinder analysis interpolation automatic control unit, be provided with an emptying device of air, this emptying device of air, gas in the liquid medicine that sampling pump extracts is discharged, gas does not enter liquid medicine with liquid medicine and analyzes automatic control unit, and avoiding influences the stability that chemical concentration is analyzed because of gas enters;
3, prevent that chemical concentration is unstable and exceed processing range, prevent that the nickel cylinder from dead cylinder occurring, turning over cylinder;
4, prevent that plating leakage, plating etc. from appearring in chemical nickel and gold surface-treated wiring board.

Fig. 1 is the structural representation of the utility model chemical nickel and gold production line;
Fig. 2 is the structural representation of the utility model nickel cylinder self-actuated controller;
Fig. 3 is the emptying device of air structural representation in the utility model nickel cylinder self-actuated controller.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, a kind of structural representation of chemical nickel and gold production line.It comprises washing cylinder 1, overhead traveling crane 2 and control box 3, and washing cylinder 1, overhead traveling crane 2 are connected with control box 3 respectively, and overhead traveling crane 2 drives core material 10 through washing cylinder 1.Irritating in washing cylinder 1 has liquid medicine, and this liquid medicine is mended by nickel cylinder 4.
As shown in Figure 2, the embodiment of the nickel cylinder liquid medicine sample analysis controller of the utility model chemical nickel gold thread.It comprises that nickel cylinder 4, sampling pump 5, emptying device of air 6, nickel cylinder liquid medicine are analyzed automatically and adds control module 7 that described sampling pump 5 and nickel cylinder liquid medicine are analyzed automatically to add between the control module 7 and is provided with emptying device of air 6.
As shown in Figure 3, described emptying device of air 6 comprises that the container 61 of sealing is arranged at feed tube 62, drain pipe 63 and the gas outlet 64 on the container, feed tube 62 is connected with sampling pump 5, and drain pipe 63 is analyzed interpolation control module 7 automatically with nickel cylinder liquid medicine and is connected, and tracheae 64 is provided with valve 65.The potpourri of air and liquid medicine enters emptying device of air 6 by feed tube, and in emptying device of air 6, air can float, and liquid medicine enters nickel cylinder liquid medicine through drain pipe 63 and analyzes interpolation control module 7 automatically.
When controlling the chemical concentration of nickel cylinder 4 by nickel cylinder self-actuated controller, because analyzing 7 of adding devices automatically, sampling pump 5 and nickel cylinder increased emptying device of air 6, make in the liquid medicine of sampling and do not have sneaking into of air, reduce the interference of air, the automatic analysis of nickel cylinder and adding device can be more stable to the analytical concentration of liquid medicine, can not exceed plating leakage and the plating that processing range causes because of chemical concentration.
Foregoing is preferred embodiment of the present utility model only, is not to be used to limit embodiment of the present utility model, and those skilled in the art are according to design of the present utility model, and appropriate adaptation of having done or modification all should be within protection domains of the present utility model.
