Embodiment 1

[0047] like Figure 1-5 As shown in the figure, an online automatic detection and control device for copper-melting tank potion for PCB production line proposed by the present invention includes a copper-melting tank 1 and an operation detection platform. The operation detection platform performs operation detection and automatic control on all copper-melting tanks 1. The operation detection platform includes a processor, the processor communicates with the acquisition and division unit, the dosing analysis unit and the cleaning and impurity removal unit. The corresponding copper melting tank 1 is sent to the processor; the working process of the collection and division unit is as follows: obtain all copper melting tanks 1 in the PCB production workshop, and mark the copper melting tank 1 as i, and i is a natural number greater than zero; obtain The starting working time of each copper melting tank 1 is set with the starting working time of the copper melting tank 1 as the sta...

Embodiment 2

[0066] like figure 1 and Figure 6-7 As shown, the difference between this embodiment and Embodiment 1 is that the switch switch assembly 3 includes a switch gear 303 , a first cavity 301 and two sets of second cavities 302 are provided below the cleaning chamber 201 , and the first cavity 301 Located between the two sets of second cavities 302 , the connecting rod 304 is arranged horizontally, the middle of the connecting rod 304 is located in the first cavity 301 , the two ends of the connecting rod 304 are installed with triangular inclined blocks 306 , and the triangular inclined blocks 306 are slidably arranged In the second cavity 302, and two sets of triangular inclined blocks 306 are located symmetrically at the midpoint of the connecting rod 304, the upper part of the triangular inclined blocks 306 is inclined; Slot 310, the push-pull rod 307 is vertically arranged and penetrates the reset groove 310, the bottom end of the push-pull rod 307 is spherical, and the sphe...

Embodiment 3

[0069] like figure 2 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the processor is communicatively connected to the maintenance and repair unit, the processor generates a maintenance analysis signal, and sends the maintenance analysis signal to the maintenance and inspection unit; After analyzing the signal, perform maintenance analysis. The maintenance analysis process is as follows:

[0070] Step R1: Obtain the current time and the last cleaning and maintenance time of the corresponding copper tank 1, perform a difference calculation between the current time and the last cleaning and maintenance time, and obtain the cleaning time interval value QWSi after the calculation, that is, the distance between the current time and the last time. Time interval between cleaning and maintenance moments;

[0071] Step R2, obtain the historical cleaning and maintenance times of the corresponding copper tank 1, and obtain the time interval be...

Abstract

The invention belongs to the technical field of PCB (Printed Circuit Board) processing, and aims to solve the problems that automatic liquid medicine adding and automatic decontamination treatment in a single copper melting tank are difficult to realize in the prior art, all copper melting tanks in a workshop are difficult to effectively supervise, the operation is complicated, and the labor cost is high. The PCB production line-oriented copper melting tank liquid medicine online automatic detection and control device comprises a copper melting tank and an operation detection platform, the operation detection platform comprises a processor, an acquisition and division unit, a dosing analysis unit, a decontamination and impurity removal unit and a maintenance and repair unit, and a liquid medicine adding pipe and a decontamination treatment mechanism are mounted on the copper melting tank. The sewage disposal mechanism is used for performing sewage disposal and impurity removal on the liquid medicine; the operation detection platform and the background supervision platform are arranged, so that the liquid medicine can be automatically and accurately added, the liquid medicine in the copper melting tank can be automatically and circularly cleaned and recycled, and all the copper melting tanks in a workshop are effectively supervised.

Description

technical field [0001] The invention relates to the technical field of PCB processing, in particular to an on-line automatic detection and control device for a copper bath potion for a PCB production line. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component. It is the support of electronic components and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is It is called printing; in the PCB manufacturing process, the PCB needs to be chemically processed in the copper bath of the chemical equipment assembly line. [0003] At present, when using the copper chemical tank to process the PCB board, it is necessary to manually detect the data information of the chemical liquid in the copper chemical tank, and according to the detection results, the chemical liquid is added to clean the internal chemical liquid, which is ...
