SMT electric automatic Stencil cleaning machine for water based cleaning machine
1.Scope of application:
The water-based stencil cleaning machine is mainly used for SMT stencil cleaning, misprint board cleaning and pcb/pcba cleaning with water-based cleaning liquid in the electronic industry. The most advanced cleaning technology in the industry is used to achieve 100% cleanliness and
environmental protection. The machine is composed of cleaning system, rinsing system, drying system and filtering system. The machine uses electricity and compressed air as energy, and manually puts the stencil into the cleaning room. After setting the cleaning, rinsing, drying and other relevant parameters in the touch screen, press the start button, and the stencil will be
automatically cleaneet cleaning process flow is completed, it will automatically stop running and reset to realize the next work flow. This machine is very convenient for operators to clean stencil, and the chief officer can improve production efficiency and quality It is a new type of high-performance automatic cleaning equipment. The equipment is rinsed with water-based liquid cleaner and DI water, without any potential safety hazards and no harm to personnel.
Stencil in cleaning
Dual liquid tank
Dimensions: 1220mm*1120mm*1850mm
-High pressure spray system specially used for washing stencil, misprint board, pcb/pcba and other processes with water-based cleaning solution.
--Dual liquid tank, equipped with heating system, to meet the needs of cleaning, rinsing and hot air drying.
--Process flow: Cleaning - chemical isolation - rough rinsing (open loop / closed loop) - fine rinsing (open loop / closed loop) - drying.
--Advanced full-automatic touch screen operation software is configured, program files are saved, and the use is extremely simple.
--System counting function, which can automatically accumulate the number of cleaned stencils and the number of circulating filters.
--Liquid and pump pressure can be displayed by panel pressure gauge to feed back equipment operation status in time.
--The spray pressure is monitored by a pressure sensor, and an alarm will be given if the pressure range is set too high.
--The resistivity monitors the rinsing solution to ensure the cleanliness. The resistivity can be set to meet the needs of different stencil processes.
--Direct liquid reflux to reduce liquid consumption .
--The overall stainless steel body is durable and resistant to acid, alkaline and other cleaning fluids.
--Rinsing water can be zero discharged for a long time through ion filtration.
--high pressure fan + hot air drying, the drying effect is faster and more complete.
--Lower operation cost. Only 30-120ml liquid is required for each cleaning. After cleaning, compressed air is used to recover the pipeline and pump residual liquid, which can reduce the liquid consumption by 50%.
2. Main cleaning products:
3. Main structure and function description
3.1 Main structure composition
The equipment is mainly composed of frame, spray cleaning system, spray rinsing system, internal mobile mechanism, cleaning solution tank, rinsing solution tank, electric heating air system, water circulation system, spray room, high-pressure air cutting system and electric control box.
3.2 Water circulation system and working principle
Double pumps and double pipes prevent liquid leakage. The liquid is directly returned to the tank for cleaning.
3.3 Internal moving mechanism
a. The mechanism adopts high-precision linear guide rail, sliding block and ball screw, which are driven by stepper motor to move left and right, ensuring accurate reset each time, long service life and convenient maintenance or replacement,
b. Operate the spray bar to move left and right to spray, and select local areas to achieve targeted spraying.
3.4 cleaning system
When cleaning, the stencil is fixed, the spray bar sprays from left to right, and all cleaning nozzles spray cleaning liquid under high pressure to clean the workpiece in an all-round scanning way. The cleaned cleaning liquid directly flows back to the cleaning liquid tank for circulating filtration and heating.
--cleaning medium: water-based cleaning solution
--cleaning solution tank material: SUS304
--nozzle material: SUS304
--water pump pressure: 0.3-0.5mpa
--water pump flow: 4t/h
--pump lift: 45m
--filtering precision: 10um
3.5 Rinsing system
During rinsing, the screen plate is fixed, the spray bar sprays back and forth from left to right, all rinsing nozzles spray DI water under high pressure to rinse the workpiece in an all-round scanning way, and the DI water after rinsing directly flows back to the rinsing tank for circulating filtration and heating.
--rinsing medium: DI water
-- rinsing tank material: SUS304
--nozzle material: SUS304
--water pump pressure: 0.2-0.5mpa
--water pump flow: 4T/h
--pump lift: 45m
--filtering precision: 10um
3.6 Storage tank
The storage tank is used to recover, store and filter the sprayed liquid. Two stainless steel primary filter screens are set at the outlet of the storage tank to protect and clean the pump, and then pass through the 10um filter.
3.7 Water circulating device
The cleaning room adopts primary filter, liquid tank filter adopts secondary filter, and stainless steel single core filter adopts tertiary filter.
3.8 Liquid level sensor
Due to the volatilization of the liquid, the workpiece is repeatedly cleaned, resulting in the continuous reduction of the liquid. The sensor detects the upper, middle and lower limits of the liquid storage capacity to alarm and control, and informs the operator of the function of adding liquid.
3.9 Temperature control device
The temperature in the liquid tank is controlled by the temperature controller to set the ideal temperature through thermocouple detection.
3.10 Heating device
The cleaning efficiency can be improved through the electric heating device of
the heating pipe.
3.11 Drying device
High pressure air cutting refers to the air flow generated by the high-pressure fan, which is heated by the heating pipe, and then the water drops on the surface of the washed workpiece are quickly separated by the air knife, so as to achieve the purpose of rapid drying of the workpiece.
