Description

Technical Field

[0001] The utility model relates to the technical field of screw surface treatment, in particular to a non-destructive feeding mechanism for screw surface treatment. Background Art

[0002] Screws are tools that use the physical and mathematical principles of the circular rotation of an object's inclined surface and friction to gradually tighten objects and parts. Screws are an indispensable industrial necessity in daily life. In order to extend the service life of screws, they are generally surface treated;

[0003] For example, the disclosed utility model provides "a surface treatment device for screws", and its announcement number is: CN210796680U. The patent includes a frame, a loading platform, an electroplating tank and a unloading platform. The loading platform, the electroplating tank and the unloading platform are fixed on the frame in sequence. Supports are arranged on both sides of the frame. Screws are arranged on the supports for horizontal rotation. The sliding block is driven by the screws to move. The sliding block moves to the top of the electroplating tank. The cylinder piston rod pushes the mounting frame to move downward until the conductive strip and the screw are completely immersed in the electroplating solution. After the electroplating work is completed, the cylinder piston rod is reset, and the power mechanism drives the sliding block to continue to move through the screw. The sliding block moves to the top of the unloading platform, and the stepper motor starts to work. The stepper motor drives the driven gear to rotate through the active gear, thereby driving the mounting lug to rotate. After rotating to a certain angle, the screws placed on the conductive strip fall on the unloading platform, completing the unloading work, and the work efficiency is high.

[0004] This patent directly flips the screws after the electroplating treatment is completed, so that the screws fall onto the unloading table under the action of gravity. The screws fall from a high place and hit the unloading table due to inertia. In this process, it is inevitable that the surface of the screws will be damaged, which will affect the electroplating treatment effect of the screw surface. Therefore, the purpose of this utility model is to improve the effect of the screw surface treatment through a lossless unloading structure. Utility Model Content
