Z-axis motion module

The utility model discloses a Z-axis motion module, which relates to the field of linear motion mechanisms, and is characterized in that the Z-axis motion module comprises a base and a support fixed on the base, one side of the support is provided with a Z-axis sliding groove, the other side of the support is provided with a limiting sliding groove, and the limiting sliding groove comprises an upper limiting side wall and a lower limiting side wall which are arranged along the Z-axis direction. A Z-axis moving part is slidably connected into the Z-axis sliding groove, a voice coil motor used for driving the Z-axis moving part to slide in the Z-axis direction is embedded in the base, an anti-collision block is arranged in the limiting sliding groove, an upper buffering pad and a lower buffering pad are arranged on the anti-collision block, and a transverse groove is further formed in the other side of the support. A guide rod is fixed to the portion, located in the transverse groove, of the support in the Z-ax
