Description

Technical Field

[0001] The invention relates to the technical field of screw assembly, in particular to a spiral screw directional feeding device. Background Art

[0002] Screws are commonly used assembly parts, which consist of a screw head and a screw rod. During the assembly process, the screws often need to be oriented first. Currently, the feeding of screws is mainly done by neatly sorting them through a spiral vibrating plate, and then picking them up for loading.

[0003] A vibrating plate for feeding PIN pins is disclosed in the patent application with reference to publication number CN117184829A. A plurality of PIN pins are neatly arranged through the vibrating plate body, and then transported in sequence with head to tail relative to each other through the feed plate. Then, in conjunction with the pushing unit and the positioning mechanism, the outermost PIN pin is clamped and pushed into the socket on the outside of the steering wheel, so as to meet the requirements of precise insertion. By rotating the steering wheel, the PIN pin can be in a vertical state with the needle facing upward, which is convenient for subsequent personnel to manually or mechanically clamp it.

[0004] The above-mentioned feeding device uses the cooperation of the pushing unit and the positioning mechanism to send the nails into the jacks on the rotating disk to complete a good feeding work. However, when it is used to transport the nails, it is necessary to repeatedly use the cooperation of the pushing unit and the positioning mechanism to complete the pushing work, and at the same time, it is necessary to repeatedly control the positioning mechanism to complete the opening and closing to cooperate with the pushing unit to complete the pushing action, which makes the overall feeding efficiency low and increases the control difficulty and feeding difficulty; At the same time, after the feeding device transports the nails to the predetermined position, it cannot actively push the nails out, which increases the difficulty of taking them out. In addition, the feeding device cannot actively clean the nails during the transportation process, which increases the difficulty of subsequent cleaning and affects the use of the nails.
