Abstract
The utility model discloses a water-washing device for a printed circuit board. The water-washing device for the printed circuit board comprises a water-washing groove, a stirrer, a potential of hydrogen (PH) value detector and a support frame, wherein the stirrer is arranged at the bottom of the water-washing groove, and the support frame is arranged above the water-washing groove. The PH value detector is fixed through the support frame and comprises a PH meter contact head and a PH value display screen, and one end of the PH meter contact head is arranged inside the water-washing groove. According to the water-washing device for the printed circuit board, through the way, a PH value of water-washing liquid inside the water-washing groove can be monitored in real time. And when the PH value of the water-washing liquid is not within normal limits, the water-washing device can give an alarm automatically, and thereby the production efficiency is improved, and the production hidden trouble is reduced.
Description
Technical field
The utility model relates to field of printed circuit board fabrication, particularly relates to a kind of printed circuit board (PCB) water washing device.
Background technology
Printed circuit board (PCB) because processing needs, need to carry out first the acid solution etching in process of production, then washes, and printed circuit board (PCB) water washing device commonly used generally is provided with rinsing bowl, product is delivered to rinsing bowl washes.And the pH value in the rinsing bowl need to be regulated according to the washing degree of printed circuit board (PCB), when the printed circuit board (PCB) of washing is more, in the rinsing bowl pH value of solution can because of printed circuit board surface with acid solution or alkali lye change, need again in the solution acid adding or add alkali to regulate, conventional is to make the operator at set intervals with the pH value of pH meter manual measurement solution, then according to circumstances carries out acid adding or adds alkali.Operation is slower like this, and has increased workman's the amount of labour, in case the workman forgets measurement, will make printed circuit board (PCB) because of washing lotion pH value discomfort injury.
The utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose provides a kind of printed circuit board (PCB) water washing device, can the Real Time Monitoring rinsing bowl in the pH value of water lotion, and when the pH of water lotion value was not in normal range (NR), water washing device was understood automatic alarm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of printed circuit board (PCB) water washing device, comprise: rinsing bowl, agitator, pH value detector, support, described agitator is located at the bottom of described rinsing bowl, described top that is set up in described rinsing bowl, described pH value detector is fixed on the top of described rinsing bowl by support, and described pH value detector comprises pH meter contact and pH value display screen, and described pH meter contact one end places in the rinsing bowl.
Preferably, described printed circuit board (PCB) water washing device comprises a warning device, and described warning device is connected with described pH value detector.
Preferably, described rinsing bowl has two, is respectively the first rinsing bowl and the second rinsing bowl, and described the first rinsing bowl connects described the second rinsing bowl, and described pH value detector is fixed on the second rinsing bowl top.The bottom of each rinsing bowl is equipped with agitator, and water lotion and printed circuit board surface are fully reacted, and accelerates washing speed.
When carrying out the printed circuit board (PCB) washing, can affect the plate face of pre-treatment when water lotion pH value is too high or too low, cause the adhesion of follow-up wet film bad, affect plate face quality, pH value detector can to the situation Real-Time Monitoring of pre-treatment washing, effectively be managed the quality of pre-treatment.
PH value detector of the present utility model can preset a normal ph scope, the pH meter contact is inserted in the rinsing bowl, last together washing is detected in real time, when pH during in normal range (NR) pH value display screen show green light, when the pH value is too high or too low, can send out a warning on the pH value display screen, in time process with the prompting operator, if untimely processing warning device can send alert song automatic alarm.
The beneficial effects of the utility model are: the utility model printed circuit board (PCB) water washing device, the pH value of water lotion in can the Real Time Monitoring rinsing bowl, and when the pH of water lotion value was not in normal range (NR), water washing device was understood automatic alarm, thereby enhance productivity, reduce production hidden danger.
Description of drawings
Fig. 1 is the structural representation of a kind of printed circuit board (PCB) water washing device one preferred embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises: a kind of printed circuit board (PCB) water washing device, comprise rinsing bowl, agitator 6, pH value detector, support, and rinsing bowl has two, is respectively the first rinsing bowl 1 and the second rinsing bowl 2.Agitator 6 has two, be located at respectively the bottom of the first rinsing bowl 1 and the second rinsing bowl 2, prop up the top that is set up in the second rinsing bowl 2, pH value detector is fixed on the second rinsing bowl 2 tops by support, pH value detector comprises pH meter contact 3 and pH value display screen 4, and an end of pH meter contact 3 places under the liquid level in the second rinsing bowl 2.
The printed circuit board (PCB) water washing device also comprises a warning device 5 in the present embodiment, and warning device 5 is connected with pH value detector.
During use, the first rinsing bowl 1 and the second rinsing bowl 2 are built-in with corresponding water lotion, and it is neutral that water lotion is, but along with the bringing into of the printed circuit board surface acid solution after the pickling, cause water lotion to be acid, and rinsing bowl is provided with automatic adding device and overflow mechanism.PH value detector is preseted a normal ph scope, generally be that normal ph is between 6.0-9.0, then after printed circuit board (PCB) tentatively being cleaned in the first rinsing bowl 1, enter and proceed in the second rinsing bowl 2 to clean, agitator 6 constantly stirs in the cleaning process, promotes water circulation to flow and is beneficial to cleaning.PH meter contact 3 one ends of pH value detector place the pH value of the second rinsing bowl 2 interior moment detection water lotions, and show by pH value display screen 4, and the workman also can adjust according to the numerical value of pH value display screen 4 in operating process.
When the pH value that detects water lotion is in the range of normal value of setting, indicator lamp on the pH value display screen 4 can show green light, when the pH value is too high or too low, can send out a warning on the pH value display screen 4, after seeing, the staff just can in time process, if after a period of time, in time do not process, then warning device 5 can send alert song and reports to the police, to prevent that to change the printed circuit board (PCB) that causes greatly impaired because of the solution pH value.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
