Introduction: UV Two-sided Exposure Box
This is my first post :)
On this site I saw a few projects UV Exposure Box, and decided to make my choice ... I decided to share with you :)
I wanted to have a two-sided exposure box. I used MDF 12mm and cast acrylic 3mm to prepare the body
Also I have prepared PCB, Proteus 8 with professional help, share all the required filters and information needed to prepare.
Then I'm going to add Fan Air Heater Temperature Heaters to dry
Step 1: PCB UV Timer Creation and Parts:
PCB has developed, Proteus 8 professional help because everyone can not have this program, share PDF files as well as original files Proteus 8
TIMER pcb parts:
arduino nano (1)
relay 12v (2)
CONNECT PIN5 2.54(1) for ENCODER modul arduino
CONNECT PIN3 2.54 (1) for buzzer
TERMINAL BLOCK P2 5MM (12)
led 3mm (inticator) (3)
transistor Power MOSFET IRFZ44E (1)
transistor 5V 1.5A Linear Voltage Regulator 7805 (1)
pcb potentiometer 10K (1)
Ceramic Capacitors 0.1uf (4)
resistor 10K (3)
resistor 300 (3)
resistor 22k (1)
resistor 680 (1)
resistor 100 (1)
Step 2: PCB for UV LED Board
I decided to prepare the UV LED board in four parts of size 15X20 cm,
Because it was possible to produce different size UV Exposure Box The distribution of the boards in my case, the pairs are above and the pair below, the total size of 20x30 cm ... A4 format
It's also easier to make this size than 20x30cm
LED board parts: (board 15X20 CM) You need 4 pieces
resistor 91 (36)X4
UV LED 3.2-3.6V 20mA 395nm - 400nm 5mm (108)x4
Total: resistor 144 pieces and LED UV 432 pieces
Step 3: Body Creation and Parts:
Apply the material to the MDF 12 mm, the size of which is given below, click on the cnc machine, if you have a CNC, I can share files for cnc svg format or CorelDRAW
material MDF 12mm
Dimensions and drawings can be viewed in PDF format "Dimensions and drawings"
4 pieces 180mm Metal Full Extension Ball Bearing Drawer Slides Smooth Runners (The pair must merge, because the tray is open completely)
Step 4: Control Panel Creation and Parts:
control panel Made cast cast acrylic 3mm,
control panel placed: LCD screen, ENCODER modul arduino time control, inclusion keys, controlled upper and lower leds ... Also relay Led lighting Added 110-220v relay, for instance if you use 110-220v lamps, which are also controlled by ...
One of the output signals for RELAY, which can be accessed by Reale Fan Air Heater Temperature Heaters to dry
Step 5: Finish
The final look
If you are interested and you have the idea to be better, please share it :)
We have a be nice policy.
Please be positive and constructive.
And what About these extra holes in timer PCB?
I do not understrand why there are two buzzers and one has three pins, I bought that piezo and it fits into that two-pins one, so what About these three pins? Thank you. And the display, are there any special specifications? Thank you so much.
What is that RV1 on PCB please?
V1 Resistance 10k. Controlling the display contrasts
What is the power supply?
It looks like 230v, but I see any power supply in the box, or am I wrong?
I used the 12 volt power supply in 20 ampers, 230 volts ... enough 4 amperes, 5 amperes are desirable.
12 volt, minimum 4amp..
