[0036] Please refer to Figures 5 to 10 , the assembly mechanism 4 includes a bracket 41, a tray 42, a guiding component 43 and a moving component 44. The bracket 41 is arranged on the frame 1. The tray 42 is slidably arranged on the bracket 41. The guiding component 43 is movably arranged on the bracket 41. The moving component 44 is used to move the guiding component 43.

[0037] The tray 42 includes a bottom plate 421 and a support sleeve 422. The bottom plate 421 is slidably arranged on the bracket 41. The support sleeve 422 is a cylindrical structure with openings at both ends. The support sleeve 422 is fixedly arranged on the bottom plate 421. The flat washer and the spring washer are sequentially placed on the support sleeve 422. A through hole (not shown in the figure) corresponding to the support sleeve 422 is formed on the bottom plate 421. The guiding component 43 can be arranged through the through hole and the support sleeve 422. Further, there are multiple support sleeves 422, and the multiple support sleeves 422 are arranged on the bottom plate 421 at equal intervals.

[0038] Further, a receiving groove 4220 is formed by downward depression of the upper end surface of the support sleeve 422. The cross section of the receiving groove 4220 is in an inverted trapezoidal structure. During assembly, the flat washer and the spring washer are sequentially placed on the receiving groove 4220.

[0039] The guiding component 43 includes a fixed sleeve 431, a guiding rod 432 and a buffer 433. The fixed sleeve 431 is arranged on the moving component 44. The guiding rod 432 is telescopically arranged on the fixed sleeve 431, and the guiding rod 432 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 the buffer 433 is telescopically arranged between the guiding rod 432 and the inner bottom wall of the fixed sleeve 431. Specifically, one end of the buffer 433 is fixedly connected to the guiding rod 432, and the other end of the buffer 433 is fixedly connected to the fixed sleeve 431. During operation, first, the guiding rod 432 passes through the support sleeve 422. The first suction nozzle 33 drives the flat washer and the second suction nozzle 34 drives the spring washer to be sequentially placed on the support sleeve 422. The third suction nozzle 35 drives the bolt to abut against the guiding rod 432. The guiding rod 432 compresses the buffer 433 under the pushing action of the bolt and then moves downward synchronously with the bolt to complete the assembly between the flat washer, the spring washer and the bolt. By providing the buffer 433, there will be no gap between the guiding rod 432 and the bolt, and the guiding rod 432 has a certain supporting force on the bolt, thereby enhancing the stability when the bolt descends.

[0040] In this embodiment, the buffer 433 is a spring. In other embodiments not shown, the buffer 433 can also be an element with elasticity and rigidity such as a stainless steel shrapnel or a copper shrapnel, which is not limited herein.

[0041] 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 arranged on the frame 1. The Y-axis linear motor 442 is connected to the X-axis linear motor 441. The Z-axis linear motor 443 is connected to the Y-axis linear motor 442. The fixed sleeve 431 is arranged on the Z-axis linear motor 443. During use, after starting the X-axis linear motor 441, the Y-axis linear motor 442, and the Z-axis linear motor 443, the guiding component 43 can slide in the X-axis direction, Y-axis direction, and Z-axis direction.

[0042] The assembly mechanism 4 further includes a magazine 45 and a pusher component 46. The magazine 45 is arranged on the frame 1. The magazine 45 is used for loading a plurality of trays 42. Specifically, the magazine 45 can load ten trays 42. The pusher component 46 includes a slider 461, a fixed frame 462, and a suction component 463. The slider 461 is arranged on the frame 1. The fixed frame 462 is connected to the slider 461. The suction component 463 is arranged on the fixed frame 462. The suction component 463 is used for sucking the tray 42. In this embodiment, the slider 461 is a linear motor. During use, after starting the slider 461, the slider 461 drives the fixed frame 462 to move towards or away from the magazine 45, and thus can suck the tray 42 out of the magazine 45 or push the tray 42 into the magazine 45.

[0043] In order to enable the suction component 463 to suck the tray 42, an electromagnet is arranged inside the suction component 463. A iron sheet is arranged on the side of the tray 42 close to the suction component 463. The electromagnet sucks the iron sheet, so that the suction component 463 can suck the tray 42, and thus the relative fixation between the suction component 463 and the tray 42 can be realized.

[0044] Further, the automatic device of the flat washer and spring washer further includes a lifting component (not shown in the figure). The lifting component is arranged on the frame 1 and is located at the bottom of the magazine 45. The lifting component is used for lifting the magazine 45. In this embodiment, the lifting component is composed of a lead screw transmission mechanism, and the structure of the lead screw transmission mechanism will not be elaborated here. In other embodiments not shown, the lifting component can also be composed of a linear motor, which is not limited here.

[0045] When a new tray 42 needs to be replaced, first start the slider 461. The slider 461 drives the fixed frame 462 to move towards the hopper 45, so that the tray 42 can be pushed into the hopper 45. Control the suction member 463 to lose power, and then start the lifting assembly. The lifting assembly drives the hopper 45 to rise, so that the suction member 463 is aligned with the new tray 42. Finally, control the suction member 463 to be powered on, so that the suction member 463 sucks the new tray 42. Start the slider 461, and the slider 461 drives the fixed frame 462 to move away from the hopper 45, so that the tray 42 can be removed from the hopper 45.

[0046] The vision component 5 is a CCD camera, and the CCD camera is used to monitor the state of the parts in the vibrating bowl 2. In this embodiment, the CCD camera is a semiconductor device that can convert an optical image into a digital signal, so as to analyze the state of the parts in the vibrating bowl 2.

[0047] During use, first place the parts in the corresponding vibrating bowl 2, and then start the driving member 31. The driving member 31 drives the first suction nozzle 33 to suck the flat washer, the second suction nozzle 34 to suck the spring washer, and the third suction nozzle 35 to suck the bolt. Start the double-acting cylinder 363 to make the two correcting members 364 approach each other, so as to correct the rod body of the bolt. Start the slider 461, and the slider 461 drives the fixed frame 462 to move away from the hopper 45, so that the tray 42 can be sucked out of the hopper 45. Then place the flat washer and the spring washer on the accommodation 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. Continue to drive the driving member 31 to move downward, and the moving assembly 44 drives the guide rod 432 to move downward synchronously. Repeat this process until the entire tray 42 is filled, and then replace the next tray 42.

[0048] The automatic device for flat washers and spring washers provided by the present invention places the parts in the corresponding vibrating bowl 2, flips and scatters the parts through slight vibration, then picks up the parts in multiple vibrating bowls 2 through the picking mechanism 3, and finally the assembly mechanism 4 assembles the picked parts. Therefore, when the number of bolts assembled is large, the operation is automated, saving time and labor.

[0049] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
