3.3 Double squeegee (option)

Standard machine uses a double squeegee with urethane scrapers or metal scrapers. This double squeegee can

be easily attached or detached from the squeegee holder by using the mount knobs. Double squeegees with a

length of 250mm, 300mm, 350mm, 400mm, 440mm or 530mm are supplied according to your order.

1. Scraper

Prints solder patterns on a board while uniformly scraping solder paste placed on the mask. Squeegee scrapers are made

of urethane or metal.

2. Mount knob

Tighten these mount knobs to install the squeegee on the squeegee holder. The squeegee with the narrower mount knob

spacing is should be installed at the front.

3. Side plate

Prevents solder paste on the mask from spreading beyond the squeegee width.

When using metal squeegees, fully insert the side plate onto the guide pin while aligning the side plate notch with the

guide pin, and tighten the thumbscrew to secure the side plate. (Fit the side plates onto both sides of the squeegee.)

4. Conveyor unit

The YSP uses a 3-stage conveyor unit separated into a board carry-in conveyor, a clamp unit (board clamp

table), and a board carry-out conveyor. The YSP equipped with an optional extended exit conveyor allows a

visual check of printed solder paste at the exit of the conveyor.

4.1 Board clamp unit (board clamp table)

The board clamp table secures a board in the printing position. During recognition or position teaching by the

vision camera, this table moves along the servo-controlled Y-axis (perpendicular to board transport direction).

This table also rotates slightly in the R direction by controlling two X axes. The conveyor rail width is

automatically adjusted according to the board width (Board Size Y).

1. Main stopper

When a board is carried in on the conveyor, the main stopper stops the board at the printing position. The main stopper

is automatically positioned by servo control according to the board length (Board Size X).

2. Push-up plate

The push-up plate moves up by servo control to clamp the board from the bottom. This push-up plate has pin insertion

holes arranged in a matrix, into which matrix pins can be inserted to support the board. (Board support jigs are optional.)

3. Flap

Presses on the board edge from the top to correct the board curvature. These flaps are automatically actuated when the

board is clamped in printing position.

4. Edge clamp

Secures the board in printing position by pushing laterally on the board edge.

4.2 Board support

Matrix pins are provided to support the board at the printing position by pushing it from the bottom. (Note that

board support jigs are optional.)

Matrix pins

For machines with matrix pin specifications, matrix pins into the holes in the push-up plate (matrix plate) in positions

that match the board.
