The utility model provides a two-dimensional motion mechanism for a pasting head of a chip mounter, and the mechanism comprises a horizontal moving mechanism and a vertical moving mechanism. The horizontal moving mechanism and the vertical moving mechanism are connected with each other through a slide rail and a synchronous belt, so as to reduce the impact from the vibration of a motor and improve the pasting precision. The horizontal moving mechanism comprises a lead screw, a first horizontal slide rail, a second horizontal slide rail, a first sliding block, a first motor, a first vertical slide rail, a second sliding block, a first limiting switch, a second limiting switch, and a tension spring. The vertical moving mechanism comprises a substrate, a second motor, a first synchronous wheel, a second synchronous wheel, a synchronous belt, a belt clamping frame, a second vertical slide rail, a third vertical slide rail, a third sliding block, a third horizontal slide rail, a fourth sliding block, a third limiting switch, and a fourth limiting switch. The mechanism provided by the utility model is reasonable in design, and is low in cost. All the materials are easy to obtain, and the mechanism is high in repeatability, is simple in structure, is easy to assemble, is stable and reliable in system operation, and is long in service life.
