Description

Technical Field

[0002] A screw machine, also known as a screw arranging machine or a screw feeding machine, is a small automated equipment that simply arranges screws in a row to improve work efficiency. It is mainly used in the production of automotive parts, and automatic assembly of computers, display screens, motors, lamps, mobile phones, etc. During use, the existing screw machine uses a screw feeding mechanism to install screws on different materials.

[0003] A screw arrangement and feeding mechanism is disclosed in the Chinese utility model patent application disclosure CN205703942U. In this screw arrangement and feeding mechanism, the screw material is moved along the conveying direction from one end of the conveying track to the other end. When passing through the blocking member, the screw with the screw body embedded in the conveying groove continues to be conveyed forward smoothly through the blocking member. Otherwise, it is intercepted by the blocking member and blown away from the conveying track by the jet member, so that the screw can be conveyed outward in a predetermined arrangement direction. The screw conveying is stable and reliable. However, the existing screw feeding mechanism has a relatively simple structure. There is no limiting device when the material is installed with screws, and it is easy to cause position deviation during the installation process, thereby affecting the accuracy of the screw machine.
