[0002] In modern industrial production, screw fastening is widely used in electronics, home appliances, automobiles and other fields, and its degree of automation directly affects production efficiency and product quality.

[0003] Some mechanisms use vibratory feeders to feed screws, which use high-frequency vibration to sort and transport screws. However, the vibration process can easily cause scratches on the screw surface and results in poor sorting stability, often leading to jamming and affecting production continuity. To solve the above problems, this application proposes a screw feeding mechanism for a high-efficiency automatic screw fastening machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screw feeding mechanism for a high-efficiency automatic screw fastening machine. The mechanism uses multiple hydraulic rods to drive the first and second vertical plates to move up and down, thus arranging multiple screws one by one for easy subsequent transport. An air pump generates air, which is then discharged through a nozzle to blow the screws and prevent jamming during transport.

[0010] Preferably, the two screw conveyor plates are inclined from high to low at the top from the front end to the rear end.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. By using multiple hydraulic rods to drive the first and second vertical plates to move up and down, multiple screws are arranged in a specific order, which facilitates subsequent transportation.

[0012] 2. Air is generated by an air pump and then discharged through a nozzle, causing the air to blow away the screws and prevent jamming during the cleaning process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 A screw feeding mechanism for a high-efficiency automatic screw fastening machine includes a base 1 for supporting the overall structure. A screw collection box 2 for centralized screw storage is fixedly connected to the top of the base 1. A collection slot 3 for storing screws is opened on the top of the screw collection box 2. A multi-section hydraulic rod 4 capable of driving the components to rise and fall is fixedly connected to the top of the base 1. A lifting plate 5 that can move synchronously with the extension and retraction of the hydraulic rod is fixedly connected to the output end of the multi-section hydraulic rod 4. A first vertical plate 6 and a second vertical plate 8 for receiving and conveying screws are fixedly connected to the top of the lifting plate 5. Both the first vertical plate 6 and the second vertical plate 8 pass through the screw collection box 2 and are slidably connected to it. The two plates achieve height adjustment through synchronous sliding. Adjustments are made to accommodate screw conveying. The bottom of the screw collection box 2 has two sealing openings. The first upright plate 6 and the second upright plate 8 pass through the two sealing openings and are slidably connected to their inner walls. The sealing openings provide space for the lifting and lowering of the upright plates. The inner wall of the collection trough 3 is fixedly connected to a fixing plate 7 for receiving screws and guiding their movement. The bottom of the collection trough 3 is inclined to facilitate the screws sliding towards the upright plates under the action of gravity. The tops of the first upright plate 6, the fixing plate 7, and the second upright plate 8 are all inclined in the same direction to achieve a smooth transition of screws between different components. The top of one side of the screw collection box 2 is inclined to guide the screws to the conveying structure.

[0018] The side wall of the screw collection box 2 is fixedly connected to a mounting plate 9 for mounting the blower mechanism. Both the mounting plate 9 and the outer wall of the screw collection box 2 are fixedly connected to screw conveying plates 10 for carrying and conveying screws. A conveying groove 11 is provided between the two screw conveying plates 10, which allows the bottom of the screw to pass through (the screw is set vertically under the action of gravity). The tops of the two screw conveying plates 10 are symmetrically inclined (inclination angle 10°-15°) to prevent the screw from deviating from the track during conveying. The tops of the two screw conveying plates 10 are inclined from high to low from the front end to the rear end, and the screw is driven to move backward by the inclination slope.

[0019] The mounting plate 9 is equipped with multiple air blowing mechanisms for assisting screw positioning. Each air blowing mechanism includes an air pump 12 that is fixedly connected to the outer wall of the mounting plate 9 and can generate airflow. The output end of the air pump 12 is fixedly connected to a delivery pipe 13 for delivering airflow. The end of the delivery pipe 13 is fixedly connected to a nozzle 14 for spraying airflow. A through opening 15 is provided on the mounting plate 9 to provide an installation position for the nozzle and allow the airflow to act directly on the screw. The nozzle 14 is located in the through opening 15 and is fixedly connected to its inner wall. The air blows slightly to make the screw shake, and the tilt of the screw delivery plate 10 prevents the screw from getting stuck.

[0020] In the working process of this utility model, the operator first puts multiple screws into the collection trough 3, and then activates the multi-section hydraulic rod 4; the output end of the multi-section hydraulic rod 4 will drive the lifting plate 5, the first upright plate 6 and the second upright plate 8 to move up and down: when the top of the first upright plate 6 moves to be level with the inner bottom of the collection trough 3, the top of the second upright plate 8 is level with the bottom of the top of the fixed plate 7, at which time the screws in the collection trough 3 will enter the top of the first upright plate 6; when the lifting plate 5 drives the first upright plate 6 and the second upright plate 8 to move to the top, the bottom of the top of the first upright plate 6 is level with the top of the fixed plate 7, so that the screws on the first upright plate 6 are transported to the top of the fixed plate 7.

[0021] Under the continuous extension and retraction of the output end of the multi-section hydraulic rod 4, the screw will gradually move to the top of the left side wall of the screw collection box 2; with the cooperation of the left side wall of the screw collection box 2 and the inclined surface of the screw conveying plate 10, the screw will move between the two screw conveying plates 10 (at this time, the bottom of the screw penetrates the conveying groove 11, and the top of the screw is located at the top of the two screw conveying plates 10), and since the two screw conveying plates 10 are inclined from front to back, the screw will gradually move backward.

[0022] At the same time, multiple air pumps 12 work to generate air, which is discharged through the conveying pipe 13 and the nozzle 14, which can blow the screws on the two screw conveying plates 10, thereby ensuring that the screws are all located between the two screw conveying plates 10 and pass through the conveying groove 11 and avoid jamming during screw conveying. Finally, the screws at the tail end will enter the screw fastening machine.
