Description

Technical Field

[0001] The utility model relates to a discharging manipulator for a pad printer. Background Art

[0002] Pad printing is one of the printing methods. It can print words, graphics and images on the surfaces of irregular shaped objects, and is now becoming an important special printing method. For example, the words and patterns on the surfaces of toy parts are printed by this printing method to achieve one-time printing and processing.

[0003] In order to achieve semi-automatic pad printing operations and relieve the labor intensity of pad printing operators, many pad printing devices are equipped with corresponding loading and unloading manipulators. For example, the utility model with the application number CN201921510781.3 discloses a pad printing device using an automatic turntable, which records a manipulator. The manipulator includes: a material taking head, a material taking head lifter and a material taking head traverser. The material taking head is arranged on the material taking head lifter, and the material taking head lifter is arranged on the material taking head traverser. The material taking head lifter is used to control the lifting of the material taking head, and the material taking head traverser is used to control the traversing of the material taking head. It is pointed out that the material taking head is a suction cup. In the actual process of toy pad printing, due to the irregular shape of toy parts, it is impossible to accurately pick up and discharge materials using a suction cup. Even if the material taking head is set as a chuck, due to the soft and irregular shape of the toy parts, using a chuck is not conducive to improving the operation of picking up and discharging materials.
