Description

Technical Field

[0001] This utility model relates to the field of screw feeding tools, and in particular to a miniature fully automatic screw feeder. Background Technology

[0002] The miniature fully automatic screw feeder is a device specifically designed for the automated feeding of small screws. Its main structure includes a feeding tray, controller, feeding track, screw distribution mechanism, and hopper. In existing miniature fully automatic screw feeders, screws enter the conveyor through the feeding tray, but misaligned screws can become stuck in the conveyor belt, causing blockages. A scraper is typically used to knock down the floating screws, but because the scraper is installed perpendicular to the conveyor, some screws cannot be removed. Furthermore, when the screws rotate synchronously with the turntable, the screw root contacts the inclined surface of the top block when the turntable reaches a certain angle, causing the screw to slowly rise off the turntable, resulting in bending and breakage at the screw root. Therefore, these technical problems need to be addressed. Utility Model Content

A short shaft is provided on the outer edge of the middle of one side of gear 3 13, passing through the groove of the connecting plate. A drive motor 6 is longitudinally installed at the lower end of gear 3 13, and is fixedly connected to the inner bottom surface of the rear end of the housing 1. The drive shaft of the drive motor 6 is equipped with gears. Gear 12 and gear 13 mesh and drive each other; the drive motor 6, gear 12 and gear 13 work together to provide power to the feeding tray 11; the gear 13, sector gear 7, gear 8 and rotating shaft 16 work together to control the scraper 9 to swing left and right; the feeding tray 11 and conveying device 10 work together to complete automatic feeding; the inclined structure and arc structure in the middle of the feeding hopper 2 and the shell 1 make it easy to keep the screws always gathered at the bottom of the feeding tray 11.

[0023] In this utility model, a mounting hole is provided in the middle of the top surface of the front end of the housing 1. A turntable 4 is vertically mounted in the mounting hole. Multiple through U-shaped grooves are vertically and equidistantly provided in the middle of the outer edge of the turntable 4. The outer edge of the bottom surface of the turntable 4 is inclined.

[0024] Working Principle: When using this utility model, the screws are first placed into the feeding bin through the feeding hopper 2. Simultaneously, the drive motor 6, conveying device 10, and servo motor 14 are started. The drive motor 6 rotates, driving gear 2 12 to rotate. Gear 2 12 meshes with gear 3 13, causing the feeding tray 11 to rotate and lifting the screws from the feeding bin. When the arc plate of the feeding tray 11 reaches its highest point, the screws fall from the arc plate onto the baffle of the conveying device 10 below. The conveyor belt then transports the screws off the baffle. Simultaneously, gear 3 13 rotates, driving the sector gear 7 to oscillate. The sector gear 7 meshes with gear 1 8, facilitating the movement of the scraper 9 via the rotating shaft 16. Synchronous oscillation knocks off excess screws from the conveyor 10 for reloading. When the conveyor 10 delivers the screws to the outlet, the servo motor 14 rotates, driving the turntable 4 to rotate. When the bushing 5 fitted on the turntable 4 aligns with the outlet of the conveyor 10, the screw enters the bushing 5. When the turntable 4 rotates to a certain position, the bottom of the bushing 5 abuts against the inclined surface of the top block 15 and gradually rises. When the bushing 5 rises to its highest point, the infrared device 3 irradiates the screw in the middle of the bushing 5, and the servo motor 14 stops rotating. When the screw is removed, the servo motor 14 and the turntable 4 continue to rotate. When the turntable 4 rotates a certain distance, the bottom of the bushing 5 detaches from the top block 15 and gradually falls back to its original position, repeating the initial steps to complete the automatic feeding.
