[0039] As Figure 2As shown, the example storage block 21 is divided into a first storage block 211 and a second storage block 212, the first storage block 211 is arranged on the rotating rod 31, and the accommodating cavity 22 on the first storage block 211 is arranged at the middle of the end of the first storage block 211 opposite to the rotating rod 31; the second storage block 212 is attached to the discharge end of the conveying track 12, and the accommodating cavity 22 on the second storage block 212 is communicated with the inner cavity of the conveying track 12. Since the two vibration disc frames 11 are used for screening the screw 2 and the nut 1 respectively, the storage block 21 needs to be divided into the first storage block 211 and the second storage block 212 to accommodate the screw 2 and the nut 1 respectively. In addition, the first storage block 211 for accommodating the screw 2 is connected with the rotating rod 31, so that the first storage block 211 can rotate with the rotating rod 31 driven by the first driving member 32, the accommodating cavity 22 on the first storage block 211 is communicated with the inner cavity of the conveying track 12, to accommodate the screw 2, and the rotating rod 31 is rotated again under the driving of the second driving cylinder 32, so that the screw 2 on the first storage block 211 corresponds to the material taking member 41, the screw 2 is taken by the material taking member 41, the screw 2 and the nut 1 are in the corresponding direction, and the screw 2 and the nut 1 are put into the splicing block 42 and can be spliced and assembled together.
[0040] In one embodiment, as shown in Figure 1 The conveying track 12 is divided into a first track 121 and a second track 122, the blocking member 23 is arranged above the first track 121, and the first track 121 corresponds to the first storage block 211, and the second track 122 corresponds to the second storage block 212; the first track 121 and the second track 122 each contain multiple tracks, and the number of the accommodating cavities 22 on the first track 121 and the second track 122 is the same as / one more than the number of the tracks. The two vibration disc frames 11 are used for screening the screw 2 and the nut 1 respectively, and the conveying tracks 12 respectively communicated with the two vibration disc frames 11 are respectively called the first track 121 for conveying the screw 2 and the second track 122 for conveying the nut 1; in order to improve the processing efficiency, the first track 121 and the second track 122 are arranged in multiple tracks, and the number of the accommodating cavities 22 on the first storage block 211 and the second storage block 212 communicated with the first track 121 and the second track 122 is the same as the number of the first track 121 and the second track 122, so as to improve the processing efficiency.
[0041] In another embodiment, as shown in Figure 1 The number of the accommodating cavities 22 on the first storage block 211 and the second storage block 212 can be one time of the number of the first track 121 and the second track 122, specifically, the first track 121 is two tracks, the accommodating cavities 22 on the first storage block 211 are four, the second track 122 is four tracks, and the accommodating cavities 22 on the second storage block 212 are eight, so as to reduce the volume of the screw and nut assembling device, and improve the processing quantity and the processing efficiency.
[0042] AsFigure 3 As shown, the first track 121 is provided with a connecting frame 33, and the connecting frame 33 is provided with a cut-off port 331 on one side adjacent to the discharge end of the first track 121, so that when the first storage block 211 is driven to lap on the cut-off port 331 by the rotating rod 31, the accommodating cavity 22 corresponds to the inner cavity of the first track 121. In order to enable the first storage block 211 to be aligned with the discharge end of the first track 121 after rotating with the rotating rod 31, the cut-off port 331 is arranged on the connecting frame 33 of the rotating rod 31 and the first driving part 32, and after the first storage block 211 is rotated with the rotating rod 31 and aligned with the discharge end of the first track 121, the end surface of the first storage block 211 will lap on the cut-off port 331, so as to avoid excessive movement of the first storage block 211, which causes the screw 2 in the first track 121 to be unable to enter the accommodating cavity 22.
[0043] As shown in the figure, Figure 1 As shown, the rotating rod 31 is provided with a thimble 38 at one end relative to the first storage block 211, the thimble 38 is connected with the eighth driving part 39 at the end away from the accommodating cavity 22, and the eighth driving part 39 is connected with the rotating rod 31. When the taking part 41 needs to take the screw 2 on the first storage block 211, the eighth driving part 39 can push the screw 2 in the accommodating cavity 22 to push out in the accommodating cavity 22, so as to facilitate the taking part 41 to take the screw 2.
[0044] As shown in the figure, Figure 4 As shown, the lower end of the connecting frame 33 is slidably connected with the first sliding rail frame 34, and the second driving part 341 is arranged on the first sliding rail frame 34 and connected with the connecting frame 33, and the connecting frame 33 drives the first storage block 211 to move left and right under the drive of the second driving part 341, so that the accommodating cavity 22 on the first storage block 211 is alternately communicated with the discharge end of the first track 121. When the first track 121 is two, and the accommodating cavity 22 on the first storage block 211 is four, in order to enable the first storage block 211 to move so that the accommodating cavity 22 on the first storage block 211 is aligned with the discharge end of the first track 121, the second driving part 341 is arranged as a self-driven sliding block on the sliding rail of the first sliding rail frame 34, that is, a driving part is arranged on the sliding block, so that the connecting frame 33 arranged on the second driving part 341 can drive the first storage block 211 to move left and right, so that the accommodating cavity 22 on the first storage block 211 can receive the screw 2, so as to be taken by the taking part 41.
[0045] It should be noted that since the first storage block 211 is movable, in order to avoid the screw 2 in the first track 121 from falling on the workbench when the first storage block 211 cooperates with the taking part 41, a blocking part 23 is arranged on the first track 121, and the output end of the blocking part 23 can extend into the inner cavity of the first track 121, so as to limit the movement of the screw 2 in the first track 121.
[0046] AsFigure 2 As shown, the lower end of the second storage block 212 is connected with a third driving member 35, and the second sliding rail frame 36 is slidingly connected with the third driving member 35. The second storage block 212 is driven to move left and right by the third driving member 35, so that the accommodating cavities 22 on the second storage block 212 are alternately communicated with the discharging end of the second track 122. When the second track 122 has four tracks, and the second storage block 212 has eight accommodating cavities 22, the second storage block 212 can be moved to accommodate the nuts 1 in the accommodating cavities 22 by moving left and right. The second storage block 212 is moved left and right by moving the third driving member 35 on the second sliding rail frame 36 left and right. Of course, the third driving member 35 is also a self-driven sliding block, that is, a driving member is arranged on the sliding block.
[0047] As shown, Figure 4 The lower end of the first sliding rail frame 34 is connected with a fourth driving member 37. The first sliding rail frame 34 is driven to move up and down by the fourth driving member 37, so as to adjust the height between the first storage block 211 and the first track 121. In addition, the screws 2 transported in the first sliding rail frame 34 have different sizes. In order to make the accommodating cavities 22 on the first storage block 211 adapt to screws 2 of different sizes as much as possible, the fourth driving member 37 is arranged below the first sliding rail frame 34. The fourth driving member 37 is an electric push rod. The first storage block 211 is adjusted by the pushing of the fourth driving member 37, so as to adjust the adaptability of the accommodating cavities 22 and the discharging end of the first sliding rail frame 34.
[0048] As shown, Figure 5 As shown, the taking member 41 further comprises a seventh driving member 412. The seventh driving member 412 has a belt transmission line 4121 corresponding to two mechanical hands 411 respectively, and a sliding rail 4122 connecting the two mechanical hands 411. The sliding rail 4122 moves with the movement of the belt on the belt transmission line 4121, and then the mechanical hands 411 move above the first storage block 211 / second storage block 212 to above the splicing block 42, or move above the splicing block 42 to above the first storage block 211 / second storage block 212, which is mainly used for taking accessories and placing them in the splicing block 42 for splicing.
[0049] As shown, Figure 6As shown, the example mechanical hand 411 includes a fifth driving element 4111 slidingly arranged on a sliding rail 4122, and a sixth driving element 4112 connected to an output shaft of the fifth driving element 4111, and a clamp 4113 connected to an output shaft of the sixth driving element 4112. The sixth driving element 4112 is a clamp cylinder. Since there is a space between the mechanical hand 411 and the first storage block 211 / second storage block 212, in order to enable the mechanical hand 411 to smoothly clamp the fittings, the mechanical hand 411 is installed on the output shaft of the fifth driving element 4111, and the fifth driving element 4111 is also an electric push rod. The mechanical hand 411 is driven by the fifth driving element 4111 to approach or move away from the fittings. In addition, the clamp 4113 is loosened or clamped on the fittings by the sixth driving element 4112, so as to facilitate the stability of the assembly of the screw 2 and the nut 1.
[0050] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the technical scope of the present application.
