Work fixture for grabbing injection parts of doll toy

Abstract

The invention relates to a work fixture for grabbing injection parts of a doll toy. An installation plate is installed on a mechanical arm and moves along with the mechanical arm. Three contact pins are arranged in the parts, corresponding to three water drainage openings of the injection parts of the corresponding doll toy, on the installation plate, and the shape of the ends of the contact pins are consistent with that of conical holes of the water drainage openings. The installation plate is further provided with a water drainage channel and a stripping mechanism, wherein the water drainage channel is used for discharging waste materials, and the stripping mechanism is used for clamping the injection parts of the doll toy when the injection parts of the doll toy are demoulded. The work fixture is simple in structure, high in automatic degree, free of hand fit work and capable of greatly improving the working efficiency; the contact pins are installed on the work fixture, the ends of the contact pins and the opening holes of the water drainage openings are arranged to be conical so that automatic correction can be carried out in a certain offset degree when the contact pins and the water drainage openings cooperate by means of the shape feature of the contact pins and the water drainage openings, the mutual cooperation strength can be improved as well, relative movement is effectively prevented, and therefore the grabbing accuracy and positioning precision are improved.

Description

technical field [0001] The invention relates to a pick-and-place device for a robot, in particular to a fixture for grabbing injection molded parts of a doll toy in the production of doll toys. Background technique [0002] Doll toys are produced by injection molding. It is necessary to make the skeleton of the doll toy first, and then inject the chest, hands, legs and other parts on the basis of the skeleton. After the injection molding work is completed in stages, the waste water used for injection molding needs to be removed. The work process is mainly operated by mechanization, but the existing injection molding equipment lacks corresponding pick-and-place devices for material retrieving, water removal, and sewage discharge, making it difficult to complete these tasks and still relying on manual assistance. This results in high staffing requirements, high costs, and low work efficiency. Contents of the invention [0003] The purpose of the present invention is to prov...
