The invention relates to a balanced counterweight mechanism for vertical movement of a linear, which comprises a stent, the linear motor, an object carrying slipway and a counterweight slipway; wherein, the linear motor has effects in the vertical direction, a stator of the linear motor is fixedly connected with the stent relatively, while a mover of the linear motor is fixedly connected with the object carrying slipway; the object carrying slipway is glidingly connected in the vertical direction relative to a stent guide, and the counterweight slipway is glidingly connected in the vertical direction relative to the stent guide; the object carrying slipway and the counterweight slipway are respectively and fixedly provided with racks in the vertical motion direction, a gear is correspondingly arranged on the stent, and the gear is rotatablely and fixedly connected correspondingly to the stent; meanwhile, the gear is meshed with the racks on the object carrying slipway and the counterweight slipway. The technical scheme solves the problems of instability, complex mechanism and large size of a vertical motion system for linear motor existing in the prior art.
