[0040] The collecting box 11 is placed on the top wall of the bottom plate of the working table 1 .

[0041] Handles 12 are fixed to both sides of the collection box 11 .

[0042] In this embodiment, the bolt mounting groove 5 provided on the rotating disk 2 is used to place the bolts, and the cooperating limiting ring 4 can drive the bolts to move to the bottom of the nut feeding assembly 8 for combined operation when the rotating disk 2 is rotated by the No. 1 motor 3. The nut feeding assembly 8 cooperates with the feeding mechanism 9 to control the falling of a nut each time, and can drive the nut and bolt to be assembled. The stripping assembly 10 is capable of pushing the assembled bolts and nuts from the feeding notch 6 into the collection box 11 for collection, and the handle 12 provided on the collection box 11 can facilitate the transportation of the collection box 11.

[0043] Example 2

[0044] like Figure 3~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0045] The nut blanking assembly 8 includes a mounting cylinder 81, which is fixed to one end of the mounting frame 7, a mounting plate 84 is fixed to one side of the mounting cylinder 81, and a rotating shell 82 is rotatably mounted at the bottom end of the mounting cylinder 81;

[0046] A first gear 83 is fixed to the outer wall of the rotating shell 82;

[0047] A second motor 85 is fixed to the bottom wall of the mounting plate 84;

[0048] A second gear 86 is fixed on the power shaft at the bottom end of the second motor 85;

[0049] The second gear 86 is meshedly connected to the first gear 83 .

[0050] The unloading mechanism 9 includes a No. 3 motor 91, which is fixed on the bottom wall of the mounting frame 7, and a mounting shaft 92 is fixed on the power shaft at the bottom of the No. 3 motor 91;

[0051] Two separation plates 93 are mounted on the mounting shaft 92;

[0052] The sides of the two separation plates 93 are both provided with notches, and the notches on the two separation plates 93 are arranged alternately.

[0053] A separation groove 13 is provided on the side wall of the installation tube 81 corresponding to the position of the separation plate 93 , and the edge line of the notch position of the separation plate 93 is located outside the inner cavity of the installation tube 81 .

[0054] The mounting tube 81 and the rotating shell 82 are both arranged in a regular hexagonal shape.

[0055] The material stripping assembly 10 comprises a vertical plate 101 , an electric push rod 102 is fixed to the bottom of the side wall of the vertical plate 101 , and a push plate 103 is fixed to the movable end on the left side of the electric push rod 102 .

[0056] The first motor 3, the second motor 85 and the third motor 91 are all servo motors or stepper motors.

[0057] In this embodiment, the installation cylinder 81 is used to store multiple nuts, and the feeding mechanism 9 is used to control the dropping of a nut each time. The distance between the two separation plates 93 is the thickness of the nut. In the initial state, the notch of the upper separation plate 93 faces outward, and the nut at the bottom is located on the top of the upper separation plate 93. When the feeding mechanism 9 is working, the No. 3 motor 91 drives the installation shaft 92 to rotate. During the rotation of the installation shaft 92, the notch position of the upper separation plate 93 gradually moves into the installation cylinder 81 until the upper separation plate 93 is no longer in contact with the nut. At this time, the bottom nut falls onto the lower separation plate 93. During the continued rotation of the installation shaft 92, the upper separation plate 93 will prop up the second nut at the bottom. At this time, the bottom nut is located on the lower separation plate 93, and the lower separation plate When the notch 93 moves into the installation tube 81, the nut at the bottom falls to the top of the bolt. At this time, the nut is just located at the rotating shell 82 (the top of the bolt is at the same height as the bottom wall of the rotating shell 82). The No. 2 motor 85 drives the No. 2 gear 86 to rotate, and the No. 2 gear 86 drives the rotating shell 82 to rotate through the No. 1 gear 83, so that the nut is screwed to the top of the bolt until the nut is separated from the rotating shell 82. At this time, the electric push rod 102 is controlled to extend, and the electric push rod 102 pushes the combined bolts and nuts into the collection box 11 for collection through the push plate 103. The above operation is repeated continuously to achieve continuous combination of bolts and nuts.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
