Abstract

The invention relates to an automatic assembly device for a watch winding stem assembly. The automatic assembly device comprises a vibration feeding machine, a material fetching tray, a clamping mechanism and a vibration assembly mechanism, wherein the material fetching tray, the clamping mechanism and the vibration assembly mechanism are installed on a machine frame. The automatic assembly device is characterized in that the clamping mechanism comprises two clamping belts which are symmetrically arranged side by side and clamping assemblies fixed to the clamping belts at equal intervals. The winding stem and a stem cap are clamped synchronously through the clamping assemblies, and then are assembled into a whole in a vibration and interference mode step by step through a vibrating plate arranged under the clamping belts and driven by an electromagnetic vibration arm. The automatic assembly device has the major characteristics that the winding stem and the stem cap are pressed inwards step by step in an electromagnetic vibration mode, so that the interference assembly process is realized; the clamping assemblies fixed to the clamping belts symmetrically arranged side by side are used for clamping the winding stem and the stem cap respectively and synchronously, lower clamping blocks in the clamping assemblies can move appropriately relative to upper clamping blocks and are used for clamping the stem cap to press the stem cap into the winding stem step by step, and therefore the interference assembly process is realized, in other words, the winding stem is protected by the upper clamping blocks.

Description

Technical field: [0001] The invention belongs to the technical field, and in particular relates to an automatic assembly device for a watch stem assembly. Background technique: [0002] The stem is a slender needle-shaped product, and a handle cap needs to be assembled at one end of the stem, and the stem and the handle cap are interference fit. At present, the one-time press-fit method is used for assembly. Due to the lack of necessary protection for the arbor, the arbor is easily broken or bent, and the defective rate is high. How to design an assembly device that can not only clamp the arbor and the handle cap, but also protect the arbor during the assembly process becomes the research object of the present invention. Invention content: [0003] The purpose of the present invention is to design an automatic assembly equipment for watch stem components that is clamped by a clamp installed on the assembly belt with the stem and stem cap, and the stem cap is gradually pre...
