A material injection mechanism

Abstract

The invention discloses a material injection mechanism, which comprises a conduit fixing part, a material channel part and an injection head connected in sequence; a plurality of linear conduit grooves for fixing material conduits are arranged side by side on the conduit fixing part; A plurality of linear injection holes corresponding to the conduit grooves are arranged side by side on the head, and the distance between the injection holes is smaller than the distance between the conduit grooves; the material channel part includes an injection chamber and a docking chamber There is a first curved surface on the injection chamber, and a plurality of first grooves with arc-shaped cross-sections and recessed into the first curved surface are distributed side by side along the bending direction of the curved surface on the first curved surface, and the docking chamber There is a second curved surface matched with the first curved surface, and there are a plurality of second grooves corresponding to the plurality of first grooves on the second curved surface; each first groove corresponds to the corresponding The second grooves are butted with each other to form a complete material channel. The invention has the characteristics of simple structure and convenient operation.

Description

technical field [0001] The invention relates to a tooling, in particular to a material injection mechanism. Background technique [0002] In the assembly of electronic parts, in the production process of transferring and positioning light and small solid materials (abbreviated as materials), such as springs and ball parts, it is sometimes necessary to use airflow to blow the materials out along the duct and blow them out according to the design Arrange them at a certain distance for the subsequent assembly process. However, it is often encountered that the set spacing is small, or even smaller than the minimum outer diameter of the duct that can be used. At this time, if the material is blown out directly from the duct, it is difficult to realize the one-time positioning of the material; if the method of blowing out multiple times is used, it will be Complicate the structure and reduce production efficiency. Contents of the invention [0003] In view of the above deficie...
