8.2.2 Function description of the component changeover table

8.2.2.1 Docking

The docking process can only be perform when the machine is power on , compressed air is sup-

plied to the machine and the safety cover have to be closed.

For docking the COT move the table into the machine as far as possible, keep safety cover closed

and press the button (One hand operation). On the left and right from the empty tape duct are two

centering pins to center the COT for the final correct pick up position.

At docking procedure the component table plate raise (depend on machine and COT height) and

is pulled into the machine automatically. Two pneumatic cylinders with cam disks on the left and

right side of the COT move the trolley.

8.2.2.2 Undocking

When machine is running:

For undocking the COT open the safety cover and press the but-

ton 1. The component table is pushed out with two additional pneumatic cylinders at the left and

right of the empty tape duct. The COT is lowered by the cam disks. The COT electrical and pneu-

matic supply will be automatically disconnected from the machine.

When machine is OFF: Remove the COT for service without electrical and pneumatic power

supply -> Open the safety cover an pull out the COT on the handles.

8.2.2.3 Adjustment pneumatic cylinder

The movement of the CAM-disks at the docking unit, left and right side can be individually adjus-

ted at the round cylinder

Note:

If you adjust the pneumatics cylinder is to be ensured that the COT is moved in parallel into the

docking unit. The docking and undocking procces of the COT should be set to

approx. 2 seconds.

8.2.2.4 Docking unit

The docking unit is fixed with a special screw to the machine so that the accuracy for picking up

of small components from the COT is guaranteed. These screw had to be fixed first before the

other screws when mounting the docking unit. (Necessary in case of changing the docking unit

COT to MTC 2 or vise versa).

Pneumatic cylinder for move the cam disks. That

means the component table plate will move hori-

zontal 43mm and 20 mm vertical into the machine.

Throttle valves for adjust the speed of the pneu-

matic cylinders (Time adjustment). The time for ad-

just should be approx. 2-3 sec.for dokking and

undocking the COT. Check the time without COT.

Pneumatic cylinders for ejection the COT during

the undocking procedure.
