[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a screw supply device, comprising: a turntable 1, an area sensor 2, a first screw box 3, a first partition 31 and a first driving mechanism 41. The outer edge of the turntable 1 is recessed inward to form a first feeding port 11; the area sensor 2 is fixed to the surface of the turntable 1 and is arranged corresponding to the first feeding port 11, and the light beam emitted by the area sensor 2 covers the first feeding port 11; the cross section of the first screw box 3 is circular, the first screw box 3 is arranged on the side of the turntable 1 away from the area sensor 2, and the first screw box 3 is connected to the turntable 1 for relative rotation; the first partition 31 is arranged in the first screw box 3, and separates the different internal spaces of the first screw box 3 along the circumferential direction to form a plurality of first screw accommodating grooves 32; the first driving mechanism 41 is arranged on the peripheral side of the first screw box 3 and is connected to the first screw box 3; the plurality of first screw accommodating grooves 32 can be driven by the first driving mechanism 41 to rotate around the central axis of the first screw box 3 to a position corresponding to the first feeding port 11.

[0038] In this embodiment, by setting an area sensor 2 corresponding to the position of the first feeding port 11 on the turntable 1 to detect the number of feeding actions of the first feeding port 11, the detection error caused by misoperation can be reduced, ensuring that the area sensor 2 is detected when feeding through the first feeding port 11. The light beam emitted by the area sensor 2 covers the first feeding port 11, which can improve the accuracy of the detection of the feeding action and prevent missed detection. The first feeding port 11 is formed by the outer edge of the turntable 1 being recessed inward, so that it has an opening facing the operator side, which is conducive to improving the convenience of feeding. The first screw box is driven to rotate by the first driving mechanism, and any first screw receiving slot can be automatically rotated to the position corresponding to the first feeding port by the drive of the first driving mechanism, without the need to manually rotate the first screw box, which has the advantages of convenience and speed.

[0039] It should be noted that the position correspondence referred to in this embodiment means that the positions are at least partially aligned, such as the first material feeding port 11 is at least partially aligned with the first screw receiving groove 32, so as to facilitate taking screws into the first screw receiving groove 32 through the first material feeding port 11, preferably completely aligned.

[0040] In this embodiment, the area sensors 2 are specifically paired light curtain sensors, comprising a light source and a light receiver positioned opposite each other. When manually removing material, the material first passes through the area sensor above the first material removal port 11, and then is removed from the first material removal port 11 into the first screw box 3. The area sensors have the advantages of a wider detection range, are not affected by ambient brightness, and provide more stable detection results.

[0041] In this embodiment, the first drive mechanism 41 may include a motor 411 and a transmission assembly. The transmission assembly may be a gear transmission structure. For example, the output shaft of the motor 411 is fixed to the driving wheel 412. The rotation of the output shaft drives the driving wheel 412 to rotate.

In some embodiments, the transmission structure may also be a belt transmission structure. This embodiment does not specifically limit this. Technicians can select a suitable transmission form according to actual working conditions. It should be noted that the turntable 1 is coaxially sleeved on the rotating shaft 414. However, when the first drive mechanism 41 drives the first screw box 3 to rotate, the turntable 1 does not rotate synchronously with the first screw box 3, thereby causing the turntable 1 and the first screw box 3 to rotate relative to each other.
