[0023] The slide trough structure 6 includes two slide troughs 8 which are installed on the frame 1 at a certain interval and parallel to each other. The slide rod structure 7 is installed on the frame 1 between the two slide troughs 8. The side of the lower end of the slide trough 8 is installed with a material distribution cylinder 10 and a material distribution cylinder 2 11. The material distribution cylinder 10 and the material distribution cylinder 2 11 work alternately, so that the hooks 5 on the slide trough 8 can fall one by one to the conveying mechanism 2 by gravity at a certain interval.

[0024] The slide bar structure 7 includes a plurality of slide bar groups fixed on the frame 1 and having the same slope as the slide slot 8. The slide bar groups each include two slide bars 9 arranged up and down, and the gap between the two slide bars 9 forms an oblique slideway for the hooks 5 to slide down one by one. The vertical spacing between the two slide bars 9 is less than the thickness of the overlap of the two hooks 5, so as to prevent the hooks 5 from overlapping. The gap between the slide bar groups does not block the hook on the hook 5, so as to prevent the hook of the hook 5 from contacting and blocking the unloading mechanism 3. The installation position of the slide slot 8 and the slide bar 9 can be changed on the frame 1, so as to facilitate the use of hooks 5 of different sizes.

[0025] The conveying mechanism 2 includes two mounting frames 12 mounted on the frame 1 in parallel with each other, with pulleys 13 at both ends of the mounting frames 12, a rotating shaft 14 is provided between the pulleys 13 at one end of the two mounting frames 12 close to the unloading mechanism 3, a motor 15 is connected to one end of the rotating shaft 14, a conveyor belt 16 is meshed and linked between the two pulleys 13 on the same mounting frame 12, and a plurality of partition grooves 17 arranged at the same interval are provided on the outer surface of the conveyor belt 16. The width of the partition groove 17 matches the width of the hook 5, so as to achieve the effect of one-to-one corresponding conveying between the partition groove 17 and the hook 5.

[0026] The suction mechanism 4 includes a support frame 21 installed on the frame 1, a telescopic cylinder 22 on the support frame 21, the movable end of the telescopic cylinder 22 is arranged downward and connected to a mounting plate 23, and a hook clamping cylinder 24 and a needle clamping cylinder 25 are installed on the mounting plate 23.

[0027] The shell unloading mechanism includes a telescopic cylinder 26 mounted on the frame 1, the movable end of the telescopic cylinder 26 faces the mounting plate 23 and is connected to a shell positioning block 27, and the shell positioning block 27 is arranged near the output end of the conveyor belt 16. The shell positioning block 27 can be installed with a positioning pin or other positioning components corresponding to the hole position of the shell, which is not limited here.

[0028] A fixing plate 18 is further provided between the two mounting frames 12, and a telescopic cylinder 3 19 is provided on the fixing plate 18. The movable end of the telescopic cylinder 3 19 faces the surface shell positioning block 27 and is connected to a hook positioning block 20. The hook positioning block 20 is provided close to the output end of the conveyor belt 16 so that the hook 5 transported by the conveyor belt 16 can fall onto the hook positioning block 20.

[0029] When the utility model is used, the hook 5 is placed on the upper end of the chute 8, and the face shell 28 parts are placed on the face shell positioning block 27. The hook 5 slides down with the slide bar 9 due to the effect of gravity. Since the vertical spacing between the two slide bars 9 is less than the overlapping thickness of the two hooks 5, the overlap of the hook 5 is effectively prevented during the sliding process. When the hook 5 slides to the lower end of the chute 8, it is blocked by the material distribution cylinder 1 10. The material distribution cylinder 1 10 and the material distribution cylinder 2 11 work successively to make the first hook 5 slide between the material distribution cylinder 1 10 and the material distribution cylinder 2 11. Then the material distribution cylinder 1 10 and the material distribution cylinder 2 11 work again successively to make the hook 5 located between the material distribution cylinder 1 10 and the material distribution cylinder 2 11 fall onto the conveying mechanism 2. At the same time, the second hook 5 arranged on the chute 8 slides between the material distribution cylinder 1 10 and the material distribution cylinder 2 11, so as to achieve the effect of cyclically unloading the hooks 5 one by one. The hooks 5 fall onto the conveyor belt 16 one by one, and the fallen hooks 5 correspond to the dividing grooves 17 on the conveyor belt 16 one by one. The motor 15 works, and drives the conveyor belt 16 to rotate through the rotating shaft 14 and the pulley 13, so as to realize the conveying of the hooks 5 one by one on the conveyor belt 16. The hooks 5 fall onto the hook positioning block 20 along with the conveyor belt 16, and the telescopic cylinder 3 19 works to move the hook positioning block 20 to the bottom of the suction mechanism 4. After the hook clamping cylinder 24 and the clamping needle cylinder 25 descend through the telescopic cylinder 1 22 to absorb the hooks 5, the telescopic cylinder 3 19 resets, and the telescopic cylinder 2 26 works to drive the surface shell positioning block 27 to rise and assemble with the hooks 5 absorbed by the suction mechanism 4, thus completing the automatic conveying and assembly work. The utility model effectively improves the feeding efficiency of the hooks 5, stably conveys the hooks 5, accurately absorbs and positions the materials, and realizes automatic conveying and assembly.
