|Applicants:||GUANGZHOU SHELL-CONNING MECHANICAL EQUIPMENT CO., LTD.
|Title:||LABELING MACHINE FOR LOWER SURFACE|
A labeling machine for a lower surface. The machine comprises: a controller; a first transport mechanism configured to feed a product to be labeled and electrically connected to the controller; and a positioning and gripping device (200) electrically connected to the controller and comprising a workpiece gripper mechanism (210) provided above the first transport mechanism. The workpiece gripper mechanism comprises a drive member (211), a holder base (212) drivably connected to the drive member, and at least three workpiece gripper correction fingers (213) provided at the holder base. The at least three workpiece gripper correction fingers can rotate with respect to the holder base, enclose and form a workpiece holding cavity (300), and approach or move away from each other. By means of rotatability of the workpiece gripper correction fingers with respect to the holder base, the present invention provides superior adaptability to hold, position, and perform attitude correction on a product having an irregular shape, thus adjusting an attitude of the product to be highly aligned with a labeling work position, and accordingly improving labeling precision and ensuring superior manufacturing quality of the product.
