Technical Field

[0001] The utility model belongs to the technical field of screw processing, in particular to a screw processing screening device. Background Art

[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts. In the production process of screws, damage often occurs due to material or process problems, resulting in the risk of reduced quality of screws shipped out of the warehouse and affecting the profit. For screws that do not require too much precision inspection, random inspections are often used for appearance inspection. This method not only wastes manpower but also has low inspection quality, resulting in the risk of reduced production quality. For this reason, we propose a screw processing screening device.
