[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The outer circular array of the outer drum 101 has a plurality of external teeth 103, which are meshed with the gear 11; the gear 11 is mounted on the output shaft of the rotating motor 10.

[0043] By adopting the above technical solution, when in use, the rotating motor 10 drives the outer cylinder 101 to rotate with the cooperation of the gear 11. During rotation, the paddle 102 arranged inside the outer cylinder 101 will pick up the screws scattered inside the outer cylinder 101. When the screws fall, they will fall on the array conveying component 3, so that the scattered screw array can be arranged in the groove in the array conveying component 3, which is convenient for conveying the screws.

[0044] In this embodiment, the array conveying assembly 3 includes a transmission frame 31, which is composed of two symmetrical plates with an L-shaped longitudinal cross-section; an inclined material guide frame 32 is welded at one end of the transmission frame 31 close to the rotating drum 1, and an L-shaped blanking plate 33 is welded at the end of the inclined material guide frame 32.

[0045] By adopting the above technical solution, when the precision screw falls on the blanking plate 33, the cap of the precision screw is larger than the gap between the two transmission racks 31 and will be stuck on it, while the wire end under the cap has a small diameter and will enter the gap between the two transmission racks 31. In this way, the precision screws can be loaded and moved slowly under the vibration of the vibration motor 5, thereby realizing the array loading of the precision screws; some precision screws that cannot accurately enter the gap between the two transmission racks 31 will fall back into the rotating drum 1, thereby realizing circular feeding.

[0046] In this embodiment, an array conveying assembly 3 for precision screw transmission is provided on the inner side of the rotating drum 1; two array conveying assemblies 3 are provided, and a fixing frame 6 is fixed between the two array conveying assemblies 3; a vibration motor 5 is provided at the bottom of the fixing frame 6; the array conveying assembly 3 is inclined from one end of the rotating drum 1 to the other end, and the inclination angle is not less than 15 degrees.

[0047] By adopting the above technical solution, the inclined array conveying assembly 3 can accelerate the moving efficiency of the precision screws under the vibration of the vibration motor 5, and improve the arrangement efficiency of the precision screws.

[0048] In this embodiment, a raised shaft hole is provided in the middle of the outer cylinder 101 and is mounted on the T-shaped shaft 2 through a bearing; the T-shaped shaft 2 is also fixedly connected to the two array conveying assemblies 3 .

[0056] The working principle of the utility model is: when in use, the rotating motor 10 drives the outer cylinder 101 to rotate with the cooperation of the gear 11. During rotation, the paddle plate 102 arranged inside the outer cylinder 101 will paddle the screws scattered inside the outer cylinder 101. When the screws fall, they will fall on the array conveying assembly 3. When the precision screws fall on the blanking plate 33, the cap of the precision screw is larger than the gap between the two transmission frames 31 and will be stuck on it, while the diameter of the wire end under the cap is small and will enter the gap between the two transmission frames 31. In this way, the loading of the precision screws can be realized, and it will move slowly under the vibration of the vibration motor 5, thereby realizing the array loading of the precision screws; some precision screws that cannot accurately enter the gap between the two transmission frames 31 will fall back into the rotating cylinder 1, thereby realizing circular feeding.
