Trap Manufacturing

Manufacturing

To manufacture my trap i needed:

Laser cutting

CNC milling

3D printing

CNC MILLING

I choose to make the shape with the alucobond which is a composite panel made up of two sheets of aluminum facing and a mineral filler core that is hardly flammable or even incombustible.i choose it epecially for it’s its weather resistance ; Temperature , rain because my trap will be installed in the agricultural fields in the open air so it will be uncovered which may damage the components inside .

I used Fusion 360 to design my trap shape

At first I fixed all the trap dimensions

For the design I started with the left side and I used it to make the top by extruding the upper part as much as the width distance

I used the miror option to make the right side then i used the same method as before to create the back and the front side

For the front side I had to design the door and the LCD shape I choose to decorate the door with a form of the target insect , these perforations are also from where the insects will enter the trap

As we know while making corners ,milling tool doesn’t give sharp corners thus joinery fails in the CNC product I used dogbone add in to add circle at all corners of a slot this is because vertical end mill cutter cannot cut square corner

I made windows on the left and right side to be cutted by the laser cutter from plexiglass , I extruded 4mm as i defined the depth

As a final step I imported the linear servo actuator and i used the move option to fix it on the top

For the setup I had to define the stock and choose my (x,y,z) axes I defined my cutter (4mm)

I started with the inner cutting going the outer cutting I selected the inner holes then i movedto the outside for the contour

The last step is to generate the Gcode For the making process I used Victor VR0907B cnc machine

3D printing

I used the 3D printer for two purposes , to print the camera mount and to print the servo actuator

Camera mount

As I mentioned ,I needed the camera to take a photo of the plate at a specific time , for that i needed to print a support for it

Servo actuator

i tried to find a mechanism to push the button-on of my camera at a specific time without my intervention .At first i thought about differet mechanisms but at the end i found tha the linear actuator can solve the issue that’s why i decided to print a pusher , a gear and a motor support

I started by designing the motor and the pusher support I used the MG996 servo motor datasheet to be sure about the dimensions which I should define in the parametres

I extruded the part where the pusher should be mounted and I extruded the perforations where the servo motor should mounted as showing bellow

Then I designed the pusher so i started by designing 2D pusher teeth then I extruded these teeth as the pusher width

Then I used the pattern option to multiplie the number

The first version wasn’t really as I was expecting ,I didn’t likethe quality at allthat’s why I changed some parametres and i also changed the PLA filament and used the ABS instead and i could have a better version

I also printed a battery box as showing bellow , It was a simple enclosure for 12v battery

Check fusion file

Also t fix the board inside the trap i designed a 3d printed box using Raise 3d printer

Check fusion file

laser cutting

Beside the cnc milling and the 3d printing i used the laser cutter

The laser cutting was the process i used to manifacture the door of the trap and the sides as showing bellow.The material I used was the plexiglass 4mm.

I choose the plexiglass because it has different charachteristics , it is 50% lighter than glass and resistant to UV rays as well asweathering which makes it perfectly suitable for outdoor installations
