A third suction nozzle 35 and a straightening assembly 36 are both disposed on the third sidewall, with the straightening assembly 36 located outside the third suction nozzle 35. The third suction nozzle 35 is used to pick up the bolt, and the straightening assembly 36 is used to straighten the bolt's shank.

[0035] Furthermore, the third suction nozzle 33 needs to pick up bolts of different specifications, so it is necessary to replace it with a corresponding suction nozzle. In order to accommodate different suction nozzles, the connecting frame 361 is slidably connected to the connecting seat 32. Specifically, a slide rail 320 and a slider 360 are provided between the connecting frame 361 and the connecting seat 32. The slide rail 320 and the slider 360 cooperate with each other.

[0037] Please see Figures 5 to 10 The assembly mechanism 4 includes a support 41, a tray 42, a guide assembly 43, and a moving assembly 44. The support 41 is mounted on the frame 1, the tray 42 is slidably mounted on the support 41, the guide assembly 43 is movably mounted on the support 41, and the moving assembly 44 is used to move the guide assembly 43.

[0038] The tray 42 includes a base plate 421 and a support sleeve 422. The base plate 421 is slidably mounted on the bracket 41. The support sleeve 422 is a cylindrical structure with openings at both ends and is fixedly mounted on the base plate 421. The flat pad and the spring pad are sequentially placed on the support sleeve 422. The base plate 421 has through holes (not shown in the figure) corresponding to the support sleeve 422. The guide assembly 43 can pass through the through holes and the support sleeve 422. Furthermore, there are multiple support sleeves 422, which are arranged evenly and at equal intervals on the base plate 421.

[0039] Furthermore, the upper end of the support sleeve 422 is recessed downwards to form a receiving groove 4220, and the cross-section of the receiving groove 4220 is trapezoidal. During assembly, the flat pad and the spring pad are sequentially placed on the receiving groove 4220.

[0040] The guide assembly 43 includes a fixed sleeve 431, a guide rod 432, and a buffer 433. The fixed sleeve 431 is disposed on the movable assembly 44. The guide rod 432 is telescopically disposed on the fixed sleeve 431 and passes through the through hole 420, the support sleeve 422, and the receiving groove 4220. The buffer 433 is received in the fixed sleeve 431 and is telescopically disposed between the guide rod 432 and the inner bottom wall of the fixed sleeve 431. Specifically, one end of the buffer 433 is fixedly connected to the guide rod 432, and the other end of the buffer 433 is fixedly connected to the fixed sleeve 431. During operation, the guide rod 432 first passes through the support sleeve 422. The first suction nozzle 33 drives the flat pad and the second suction nozzle 34 to sequentially place the spring pad onto the support sleeve 422. The third suction nozzle 35 drives the bolt to abut against the guide rod 432. Under the pushing action of the bolt, the guide rod 432 compresses the buffer 433 and then moves downward synchronously with the bolt to complete the assembly of the flat pad, the spring pad, and the bolt. With the buffer 433 in place, there is no gap between the guide rod 432 and the bolt, and the guide rod 432 provides a certain supporting force to the bolt, thereby enhancing the stability of the bolt during descent.

[0041] In this embodiment, the buffer 433 is a spring. In other embodiments not shown, the buffer 433 may also be an elastic and rigid element such as a stainless steel spring or a copper spring, which is not limited here.

[0042] The moving component 44 includes an X-axis linear motor 441, a Y-axis linear motor 442, and a Z-axis linear motor 443. The X-axis linear motor 441 is mounted on the frame 1, the Y-axis linear motor 442 is connected to the X-axis linear motor 441, and the Z-axis linear motor 443 is connected to the Y-axis linear motor 442. A fixing sleeve 431 is mounted on the Z-axis linear motor 443. In use, activating the X-axis linear motor 441, the Y-axis linear motor 442, and the Z-axis linear motor 443 allows the guide component 43 to slide in the X-axis, Y-axis, and Z-axis directions.

[0043] The assembly mechanism 4 also includes a hopper 45 and a pushing assembly 46. The hopper 45 is mounted on the frame 1 and is used to load multiple trays 42. Specifically, the hopper 45 can hold ten trays 42. The pushing assembly 46 includes a slider 461, a fixed frame 462, and a suction member 463. The slider 461 is mounted on the frame 1, the fixed frame 462 is connected to the slider 461, and the suction member 463 is mounted on the fixed frame 462 and is used to suction the trays 42. In this embodiment, the slider 461 is a linear motor. In use, when the slider 461 is activated, it drives the fixed frame 462 to move closer to or further away from the hopper 45, thereby suctioning the trays 42 out of the hopper 45 or pushing the trays 42 into the hopper 45.

[0044] In order to enable the suction member 463 to pick up the material tray 42, an electromagnet is provided inside the suction member 463, and an iron sheet is provided on the side of the material tray 42 near the suction member 463. The electromagnet picks up the iron sheet, so that the suction member 463 can pick up the material tray 42, thereby achieving relative fixation between the suction member 463 and the material tray 42.

[0045] Furthermore, the automated device for the flat pad includes a lifting assembly (not shown in the figure). The lifting assembly is mounted on the frame 1 and located at the bottom of the hopper 45. The lifting assembly is used to lift the hopper 45. In this embodiment, the lifting assembly is composed of a screw drive mechanism; the structure of the screw drive mechanism will not be described in detail here. In other embodiments (not shown), the lifting assembly may also be composed of a linear motor; this is not limited here.

[0046] When a new tray 42 needs to be replaced, firstly, the sliding member 461 is activated, which drives the fixed frame 462 to move closer to the hopper 45, thereby pushing the tray 42 into the hopper 45. Then, the suction member 463 is de-energized, and then the lifting assembly is activated, which drives the hopper 45 to rise, so that the suction member 463 is aligned with the new tray 42. Finally, the suction member 463 is energized, so that it picks up the new tray 42. Then, the sliding member 461 is activated, which drives the fixed frame 462 to move away from the hopper 45, thereby removing the tray 42 from the hopper 45.

[0047] The vision component 5 is a CCD camera, which is used to monitor the state of the part within the vibratory feeder 2. In this embodiment, the CCD camera is a semiconductor device capable of converting optical images into digital signals, thereby enabling the analysis of the state of the part within the vibratory feeder 2.

[0048] In use, the parts are first placed in the corresponding vibratory plate 2. Then, the drive unit 31 is activated, which drives the first suction nozzle 33 to pick up the flat pad, the second suction nozzle 34 to pick up the spring pad, and the third suction nozzle 35 to pick up the bolt. The bidirectional cylinder 363 is activated to bring the two straightening components 364 closer together, thereby straightening the bolt. The sliding component 461 is activated, which drives the fixed frame 462 to move away from the hopper 45, thereby picking up the tray 42 from the hopper 45. Then, the flat pad and the spring pad are placed on the receiving groove 4220 in sequence. After that, the third suction nozzle 35 moves to the support sleeve 422 and abuts the bottom of the bolt against the guide rod 432. The drive unit 31 is driven to move downward, and the moving component 44 drives the guide rod 432 to move downward synchronously. This process is repeated until the entire tray 42 is filled, and then the next tray 42 is replaced.

[0049] The picking mechanism or automated device for flat and spring washers provided by this utility model uses a first suction nozzle 33 to pick up the flat washer, a second suction nozzle 34 to pick up the spring washer, and a third suction nozzle 35 to pick up the bolt. The straightening member 364 has a straightening groove 3640 with a V-shaped structure. The groove wall of the straightening groove 3640 makes point contact with the bolt shank, which can straighten the bolt shank. This allows the flat washer and the spring washer to be easily fitted onto the bolt, resulting in high assembly efficiency.

[0050] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model.
