Abstract
The invention provides a circuit board cleaning liquid automatic preparation system comprising a primary liquid trough and a mixed liquid storage trough. A liquid level sensor is arranged in the primary liquid trough. The primary liquid trough is connected with a proportioning pump. A PH meter sensor is arranged in the mixed liquid storage trough. Communication is performed by adopting configuration programming touch screen and a control box by a Modbus protocol connected through RS232. A user only needs to input set concentration through a touch screen input window and performs simple control operation on an electromagnetic valve to read mass flow rate of a flowmeter so as to obtain a solution of corresponding concentration through calculation of the proportioning control box. The liquid level of the primary liquid trough is observed by using the liquid level sensor so as to timely perform liquid supplementing; and cleaning liquid in proportioning and use are monitored in real time by using the PH meter so as to analyze influence of the PH value of the solution to cleanliness of a circuit board subsequently, and thus operation, setting and monitoring are convenient.
Description
Technical field
The present invention relates to the technical field of chemical solution preparation, particularly relate to a kind of circuit card scavenging solution automatic preparation system.
Background technology
Water washer is the specific equipment carrying out circuit card cleaning after PCB components welding, and the scavenging solution used is the certain density diluent obtained by thin up by scavenger specially. Water washer does not possess the function of automatic mixing in scavenging solution preparation, mostly adopt the method for artificial preparation at present, and manually prepare the accurate control that can not complete concentration of lotion, cannot qualitative assessment on the impact of PCB assembly cleaning quality on concentration of lotion.
Summary of the invention
The object of the present invention, to be solved the deficiency of water washer in scavenging solution automatic preparation exactly, concentration of lotion is controlled proportioning automatically, the PH value of configured solution is automatically monitored simultaneously. And then a kind of circuit card scavenging solution automatic preparation system is proposed.
The present invention is by the following technical solutions:
A kind of circuit card scavenging solution automatic preparation system, comprising: stoste groove, mixed solution holding tank;
Being provided with liquid level sensor in described stoste groove, described stoste groove is connected with proportioning pump;
Described mixed solution holding tank is provided with PH flowmeter sensor;
Described proportioning pump is connected with gage probe with burden control case respectively by certainty ratio mixed solution magnetic valve; Described gage probe is connected with mixed solution holding tank by waterway electromagnetic valve.
In technique scheme, described burden control case adopts micro-chip as master control chip.
In technique scheme, described gage probe is Coriolis flowmeter.
In technique scheme, described burden control case is connected with touch-screen, and the Modbus that this touch-screen adopts configuration Soft-ware programme control to be connected by RS232 with burden control case communicates.
It is an advantage of the current invention that: stoste and water are carried out fixing quantity, it is possible to go out the scavenging solution of desired concn according to simple setting proportioning; Adopt the touch-screen of configuration programming by Modbus agreement and burden control case communication, user only needs to be inputted the concentration of setting by touch screen input window, and certainty ratio mixed solution magnetic valve and waterway electromagnetic valve are carried out simple control operation, just can obtain the solution of respective concentration, adopt PH meter that the scavenging solution in proportioning and use is carried out Real-Time Monitoring, facilitating post analysis solution PH value on the impact of circuit card cleaning degree, whole system operation, setting and supervision are convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the structural representation of the circuit card scavenging solution automatic preparation system of the present invention.
Fig. 2 is the structure block diagram of the circuit card scavenging solution automatic preparation system of the present invention.
In figure, Reference numeral represents and is:
1-stoste groove, 2-mixed solution holding tank, 3-burden control case, 4-touch-screen, 5-Coriolis flowmeter, 6-certainty ratio mixed solution magnetic valve, 7-waterway electromagnetic valve, 8-proportioning pump, 9-liquid level sensor, 10-PH flowmeter sensor.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of circuit card scavenging solution automatic preparation system of the present invention by stoste groove 1, mixed solution holding tank 2, burden control case 3, touch-screen 4, Coriolis flowmeter 5, certainty ratio mixed solution magnetic valve 6, waterway electromagnetic valve 7, proportioning pump 8, liquid level sensor 9, PH flowmeter sensor composition 10. Wherein, touch-screen 4 adopts configuration Soft-ware programme, is connected Modbus protocol with adopting RS232 between burden control case 3; The 485 Modbus protocol communications being connected are adopted between the transmitter of Coriolis flowmeter 5 with burden control case 3.
Described proportioning pump 8 is the proportioning pump not needing the ratio of other motivating forces adjustable; It drives the suction of stoste by tap water, completes the configuration of certainty ratio solution. The independent thin up of certainty ratio solution that final setting concentration is exported by proportioning pump obtains.
In burden control case 3, principal controller is the C8051F020 micro-chip with two serial ports, it obtains setting strength of solution from touch-screen, corresponding magnetic valve action is triggered according to the magnetic valve triggering situation of touch-screen, and carry out instruction and return to touch-screen, the total mass flow rate that reading quality under meter transmitter is uploaded by the Modbus agreement that 485 connect simultaneously, current concentration is calculated according to the situation that current magnetic valve is opened, and the Modbus agreement connected by RS232 returns to touch-screen shows current concentration in real time, when certainty ratio mixed solution or water reach respective stored groove store content maximum value under current setting concentration, automatically corresponding magnetic valve is closed, now trigger another way solenoid valve by touch-screen, then in burden control case, computing system can calculate according to setting concentration real time contrast, automatically the current magnetic valve opened is closed after reaching setting concentration, complete the automatic preparation of scavenging solution. liquid level sensor is placed in stoste groove, and carries out communication by 4-20mA electric current signal between burden control case, and level condition is returned to touch-screen and carries out real-time level instruction by burden control case. PH flowmeter sensor is placed in mixed solution holding tank, detects the PH value of mixed solution in real time when scavenging solution proportioning and circuit card are cleaned, and exports 4-20mA electric current signal to burden control case, and the PH value that the process of burden control case obtains returns to touch-screen and shows in real time.
Obviously, above-described embodiment is only for example is clearly described, and not to the restriction of the mode of enforcement. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without the need to also cannot all enforcement modes be given exhaustive. And the apparent change thus extended out or variation are still among the protection domain of the invention.
