Description
Technical Field
The utility model relates to a feeding mechanism for large-size screws. Is applicable to the technical field of screw feeding equipment.
Background
The connection between the parts of the industrial products is mostly screw connection. I.e. by fastening one part to the other by means of bolts or screws. In manual operation, the screw is typically manually fed onto a screwdriver bit or socket of a power tightening tool (e.g., a power screwdriver) and the tightening tool is then manipulated to tighten the screw.
In the process of factory automation, a method of using a robot to carry an electric tightening tool to tighten the screw replaces manual tightening. However, there are technical difficulties: how to mount the disordered screws on the screwdriver head or sleeve of the electric tightening tool one by one according to the required gesture.
The current common methods are blowing nails and sucking nails. The blowing nails are generally arranged in order from disorder by vibrating a disc or other mechanism, then fed one by one to the electric tool through a guide tube, enter the inside of the batch head from the side of the special batch head, and then are pushed forward for fastening. In the process of the screw from the guide pipe to the inside of the batch head, compressed air is introduced into the guide pipe, and the screw is blown forward. The suction nails form negative pressure at the head of the screwdriver through the air pipes, orderly and sequentially arranging screws are sucked onto the screwdriver from the screw placing table, and the screw is required to be upwards from the unthreaded big head. The 2 methods have higher requirements on the screw, are basically only applicable to screws with diameters below M8 and lengths below 40mm, and have the fastening posture required to be as vertically downward as possible (the big head of the screw is upward). The 2 methods are widely applied to the small screw fastening in the 3C electronic industry.
The automotive industry has a great demand for automatic tightening. And for the screws of the automobile chassis, the front auxiliary frame, the rear auxiliary frame and the power battery of the new energy automobile are fastened to the automobile body, basically the screws are screws above M10, the length of the screws is more than 40mm, and the screws are fastened from bottom to top. When the automatic screwing operation of the automobile chassis on the automobile production line is carried out, the screws are required to be downwards arranged according to the heads of the screws and are put into the head or the sleeve of the electric screwing tool from top to bottom, and the method for blowing and sucking the screws cannot meet the requirements.
