Circuit board stripper

A circuit board stripper comprising:

• a deck (11) having a top pattern plate (12) for supporting circuit boards (50), said deck (11) defining a plurality of first through-holes (13), said pattern plate (12) defining a plurality of second through-holes (14) aligned with said first through-holes (13) of said deck (11);
• a slider (30) movable under said deck (11), said slider (30) having a top face formed with a plurality of slopes under said aligned through-holes (13,14) of said deck (11) and said pattern plate (14);
• a plurality of lifting pins (17) extending upward through said aligned through-holes (13,14), each of said lifting pins (17) being formed with a bottom wheel (18) adapted to roll on corresponding one of said slopes of said deck (11) so that said lifting pins (17) are lifted up when said slider (30) is moved in a first direction and are lowered down when said slider (30) is moved in a second direction opposite to said first direction;
• and
• a pneumatic cylinder (21) having a ram (22) for moving said slider (30) in said directions.
