Specific embodiments

[0031] For the convenience of understanding the present utility model, the following will describe the present utility model more comprehensively and meticulously in conjunction with the specification drawings and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.

[0032] As Figure 1 As shown, an automatic material sorting and transfer device provided in this embodiment includes a frame 100 and a feeding mechanism 200, a material sorting mechanism 300, a transfer mechanism 400, and a conveying mechanism 500 installed on the frame 100.

[0033] As Figure 2As shown, in this embodiment, the feeding mechanism 200 includes a temporary storage bin 201, which is fixedly mounted on the frame 100. The bottom of the temporary storage bin 201 is open, and is connected to a leakage bottom box 202 inclined to one side of the material sorting mechanism 300. A discharge port is formed between the leakage bottom box 202 and the side wall of the temporary storage bin 201. The leakage bottom box 202 is mounted on the frame 100 through an elastic member, and a vibration motor is fixedly mounted at its bottom. High-frequency vibration is generated by the vibration motor during the feeding stage to ensure continuous and dispersed feeding. A blocking mechanism for closing the discharge port is provided at the discharge port. When feeding is not required, the material in the temporary storage bin 201 is blocked by the blocking mechanism to achieve accurate matching of the feeding rhythm and the material sorting efficiency. The blocking mechanism includes a baffle 203 pivotally connected to the front end of the leakage bottom box 202, and a blocking cylinder 204 that drives the baffle 203 to flip.

[0034] like Figure 3 , Figure 4 As shown, the material sorting mechanism 300 includes a material sorting tray 301, and a plurality of accommodating grooves 302 are arranged in an array on the bottom plate of the material sorting tray 301, each accommodating groove 302 is used to accommodate a material, one side of the material sorting tray 301 is located below the discharge port of the temporary storage bin 201, and the other side is open, and a return bin 303 is provided below the open side; a swing mechanism 304 is provided at the bottom of the material sorting tray 301, and the swing mechanism 304 is used to drive the material sorting tray 301 to tilt toward one side of the return bin 303 and drive the material sorting tray 301 to swing back and forth. The material sorting tray 301 uses gravity and inertia to automatically return the material in the accommodating groove 302 through the composite motion of tilting + reciprocating swinging back and forth, and the excess material falls into the return bin 303 from the open side.

[0035] In this embodiment, the swing mechanism 304 includes a mounting plate 3041, and a rotating shaft 3042 is fixedly connected to the bottom of the mounting plate 3041.

[0036] like Figure 5As shown, the transfer mechanism 400 includes a linear moving module 401 straddling the material sorting mechanism 300 and the feeding station of the conveying mechanism 500, a lifting cylinder 402 connected to the linear moving module 401 through a connecting beam 404, and a suction cup assembly connected to the output end of the lifting cylinder 402 through a connecting frame 405. The suction cup assembly includes a suction cup 403 connected to a negative pressure air source and a plurality of suction nozzles arranged in an array on the bottom surface of the suction cup 403. The suction cup 403 is driven by a negative pressure air source, and the suction nozzle array corresponds to the containing groove one by one, which can quickly and gently suck the material. At the same time, each suction nozzle can only suck one material at a time, avoiding the situation where multiple materials appear in the material receiving groove 5021 on the carrier 502.

[0037] See also Figure 1 , Figure 6 , Figure 7 The conveying mechanism 500 includes a conveying chain 501 with a carrier 502 and a driving device, and a material receiving groove 5021 is arranged in an array on the carrier 502. In this embodiment, the conveying mechanism 500 includes two parallel and spaced conveying chains 501, and the conveying chains 501 are connected to the driving motor 503 through a sprocket 504 and a transmission shaft. A connecting block 506 is fixedly connected to the chain plate on the inner side of the two conveying chains 501, and the carrier 502 includes a plurality of strip-shaped bearing bars 5022, and the two ends of the strip-shaped bearing bars 5022 are respectively connected to the connecting block 506 on the conveying chain 501 through an L-shaped connecting seat 5023. A plurality of material receiving grooves 5021 are evenly distributed on the strip-shaped bearing bars 5022 along the length direction. The strip-shaped bearing bars 5022 are operated in a stepping cycle with the conveying chain 501, and can continuously receive and transfer materials, forming an assembly line operation, and improving the conveying efficiency and the stability of the production rhythm.

[0038] In this embodiment, the conveying mechanism 500 also includes a chain support rail 505 fixedly mounted on the frame 100, and a concave rail groove is provided on the side of the chain support rail 505, and the outer side of the conveying chain 501 is located in the rail groove. A positioning cylinder 507 is fixedly mounted on the frame 100 on one side of the chain support rail 505, and a positioning plate 508 is connected to the output end of the positioning cylinder 507. A plurality of ejectors 509 are fixed at intervals on the side of the positioning plate 508 close to the conveying chain 501, and a positioning socket corresponding to the ejector 509 is provided on the connecting block 506 and the L-shaped connecting seat 5023. The cooperation between the ejector of the positioning cylinder and the positioning socket of the carrier ensures that the carrier is accurately positioned at the material receiving station.

[0039] like Figure 8As shown, to achieve the recycling of the excess materials during the material sorting process of the return bin collection, in this embodiment, the feeding mechanism 200 further includes a main storage bin 206, a hoist 207, and a return conveyor belt 208. The feeding end of the hoist 207 is connected to the bottom of the main storage bin 206, and the discharging end extends above the feeding port of the temporary storage bin 201. The receiving end of the return conveyor belt 208 is located below the return bin 303, and the discharging end extends above the main storage bin 206. Through the cooperation of the main storage bin 206 and the hoist 207, continuous feeding and material recycling are achieved.

[0040] In this embodiment, the middle of the storage bin is separated into two cavities by a partition 205, and two discharging ports, two sorting trays 301, and two suction cups 403 are correspondingly arranged. By physical isolation, a dual working unit is formed to avoid the problem of reduced material dispersion caused by the decrease in the effective vibration area ratio of a single large-sized sorting tray. The dual suction cup assembly can achieve cavity-by-cavity and time-sequential adsorption operations. Compared with the single suction cup full-volume grasping mode, the working area of a single negative pressure adsorption and the air consumption are significantly reduced. Combined with the split control of the negative pressure air source, the system power consumption can be reduced, and at the same time, the risk of material falling off caused by local air pressure fluctuations during large-capacity adsorption can be avoided.

[0041] To eliminate the gap between the two suction cups 403 during discharging, a horizontally arranged linear guide rod is provided on the connecting frame 405. The suction cup 403 is slidably connected to the linear guide rod through a sliding seat. A distance adjustment cylinder 406 is fixedly installed on the connecting frame 405, and the output end of the distance adjustment cylinder 406 is fixedly connected to the suction cup 403 to drive the two suction cups 403 to approach and reset. While increasing the single handling capacity, the efficiency and accuracy of material sorting and transfer are maintained.

Accordingly, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and that modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
