Description

A nut automatic marking device

Technical Field

The utility model relates to the technical field of nut processing, in particular to an automatic nut marking device.

Background Art

Nuts are parts that tightly connect mechanical equipment. They are screwed together with bolts of the same specifications through the inner threads and are used for fastening. During the production and processing of nuts, nuts need to be marked to facilitate the identification of parameters such as the size of the nuts. Currently, automatic laser marking machines are generally used to mark nuts. Automatic laser marking machines are devices that use laser beams to mark the surface of objects. The surface material of the object is evaporated to reveal the deep material of the object, so that exquisite patterns, trademarks and texts can be marked.

In the process of nut marking, the nuts are usually fixed on an automatic laser marking machine manually for marking, and then the nuts are removed manually. This method is extremely labor-intensive and has low marking efficiency. Alternatively, the nuts are neatly placed on a conveyor belt manually, and the nuts are transported to an automatic laser marking machine via the conveyor belt for marking. This method requires the conveyor belt to transport the nuts rhythmically to ensure the smooth progress of the marking process, resulting in a complex production equipment structure and high cost. At the same time, this method still requires labor and is difficult to achieve fully automatic nut marking.

3. Under the resistance of the spiral rod, the vertical nuts and stacked nuts can be automatically laid flat; at the same time, the rotating spiral rod can provide a friction force along the axial direction of the spiral rod for the nut contacting the spiral rod through its spiral structure, so that the nut will be offset to facilitate the laying of the nut and prevent the nut from being stuck in the laying mechanism because its axial direction is parallel to the axial direction of the spiral rod.

4. The nuts can be conveyed to two automatic marking mechanisms respectively through the first conveyor belt and the second conveyor belt for simultaneous processing to improve processing efficiency.
