4. When adjusting the foot, it is recommended to group 2 feet as one set and adjust the level in

each direction

5. The feet of the machine must be supported at uniform force, which is adjusted by tightening the

lock nut of the foot so that uniform force is applied to the feet. Check if there is any loose foot.

Tighten the lock nuts for 4 legs after leveling is finished.

Caution

If the level of the machine is not adjusted, it has influence

on the accuracy of the machine. Be sure to level the

machine and check if the feet of the machine are tightened

properly.

There must be no grease on the lock nut and foot nut. If

there is grease on them, clean it completely. Otherwise, the

nut is loosened during machine operation, which may

damage the machine.

3.1.3.3. In-line installation procedure

The procedure for adjusting the level of the machine is given below.

1. First, align the entry station and exit station based on the fixed frame of the front work station.

Feed the sample PCB in and adjust the conveyor width to the PCB width manually and then

align the conveyor while pushing the PCB as shown in the following figure.

2. After moving the new machine near to the existing one, lower the foot of the machine so that it

is aligned level with the existing machine. Then adjust the level keeping the level difference

below 0.05mm/m. (Any slight difference in level can be felt using a finger tip.)

3. Using a lever, move the machine to the position where the gap between the existing machine

and the edge of the conveyor can be kept between 3~5mm.

4. Perform the procedure of leveling the machine again. (Refer to “2.1.3.2 Installation procedure

for stand alone“.)

5. Put the PCBs on each conveyor of the two machines, and set the machines so that the level

difference is 0.05~0.50mm, enough to allow the PCBs to move downward. Essentially, the

slope of the conveyor shall be set to allow for the “Downflow” of the PCB in the direction in

which the PCB is moving.

6. To ensure the straight movement of the PCB between machines, the machines must be installed

correctly so that there will be no unparallel gap at either front or rear side of the PCB, when the

PCB is tightly contacted to the reference line.

7. Adjust the machine level until there is no blocking sound at the gap between machines while

pushing the PCB slowly.

8. In the case of level adjustment between two machines, if the leveling of the postprocess

machine was finished but the level does not match with the conveyor of the pre-process

machine, perform as follows. The level of the reference surface must be identical in the left and

right side direction of the PCB (PCB flow direction), and the level difference must be less than

0.1mm/m in the front and rear side direction of the PCB. The PCB must pass smoothly without

being blocked when it is pushed through the machines by hand at low speed.

9. For the next procedure, refer to “ Installation procedure for stand alone“.
