The output shaft of the lifting drive motor 11-4 is connected to the crank 11-6 through a synchronous belt transmission mechanism 11-5. When the crank 11-6 rotates, the inclined push plate 11-10 is driven to reciprocate up and down through the connecting rod 11-8. A rear guide column 11-13 which is consistent with the movement direction of the inclined push plate 11-10 is also fixed on the support frame 11-1, and a sliding seat 11-12 which cooperates with the sliding guide of the rear guide column 11-13 is provided on the inclined push plate 11-10 located at the back, thereby ensuring the reciprocating motion stability of the inclined push plate 11-10. The movement stroke of the inclined push plate 11-10 is equal to or slightly greater than the height difference between the adjacent inclined push fixing plate 11-11 and the bottom side of the discharge tray 11-2 and the corresponding inclined push fixing plate 11-11. When the inclined push plate 11-10 is in the lower stroke position, the top of the inclined push plate 11-10 is lower than or flush with the corresponding inclined push fixing plate 11-11 or the discharge tray 11-2. When the inclined push plate 11-10 moves to the upper stroke position, the top of the inclined push plate 11-10 is higher than or flush with the adjacent upper inclined push fixing plate 11-11. In this way, the inclined push plate 11-10 can push the rod-shaped part 400 upward by a step distance every time it reciprocates, and can keep the part lying flat during this process. The material dropping inclined plate 11-3 is fixed on the upper edge of the inclined push fixing plate 11-11 at the top, and is inclined toward the conveying channel direction of the conveying mechanism 12, so that the rod-shaped parts 400 lifted to the top roll along the material dropping inclined plate 11-3 onto the conveying mechanism 12. Support feet 11-7 are also provided at the bottom of the support frame 11-1 to facilitate the stable support of the parts loading device 100. With the above-mentioned lifting mechanism 11, the inclined push plate 11-10 reciprocates and pushes the rod-shaped parts 400 upward step by step. During the lifting process, the rod-shaped parts can be automatically arranged neatly, which provides guarantee for the subsequent parts conveying and counting, and the parts lifting movement is stable.

[0059] catch Figure 2 and Figure 3 As shown, the above-mentioned conveying mechanism 12 includes a conveying transverse plate 12-1, a conveying drive motor 12-2, a driving pulley 12-3, a driven pulley 12-4, a tensioning pulley 12-5, a conveyor belt 12-6, a conveying side baffle 12-7 and a blanking chute 12-8. The conveying transverse plate 12-1 is horizontally fixed on the top of the support frame 11-1 and extends to the other side from the blanking chute 11-3. The conveying drive motor 12-2 is installed on the conveying transverse plate 12-1, the driving pulley 12-3 is connected to the output shaft of the conveying drive motor 12-2, and the driven pulley 12-4 is installed on the other side of the conveying transverse plate 12-1. At one end, the conveyor belt 12-6 is tensioned between the driving pulley 12-3 and the driven pulley 12-4 through the tensioning pulley 12-5. The conveyor belt 12-6 located at the upper part between the driving pulley 12-3 and the driven pulley 12-4 is in a horizontal state. The conveyor belt 12-6 is composed of two belts with circular cross-sections, and a "V"-shaped groove is formed between the two belts. The rod-shaped part 400 can be stably positioned in the "V"-shaped groove. The conveying side baffle 12-7 is arranged on one side of the conveyor belt 12-6 and is opposite to the blanking inclined plate 11-3, so as to block the rod-shaped parts 400. The structure is simple and the conveying is stable. The blanking chute 12-8 is located on the opposite side of the conveying side baffle 12-7, and the blanking chute 12-8 is arranged on the side close to the blanking slant plate 11-3, and is used to guide the rod-shaped parts 400 overlapped on the conveyor belt 12-6 into the blanking chute 12-8. A reflux port 12-9 for returning the rod-shaped parts 400 to the discharge tray 11-2 is also arranged between the blanking chute 12-8 and the support frame 11-1. In this way, after the lifting mechanism 11 conveys the rod-shaped parts 400 to the conveyor belt 12-6, if there are parts stacked together, they can roll down when passing through the blanking chute 12-8. The rolled parts can be manually sent back to the discharge tray 11-2 from the reflux port 12-9, and participate in the parts lifting again, which effectively avoids the rolling or overlapping conveying and counting of parts, and ensures the accuracy of the parts packaging quantity.

[0060] See also Figure 2 , Figure 3 , and combined with Figure 5As shown, the counting and pushing mechanism 13 comprises a pushing driver 13-1, a limiting pushing block 13-2 and a discharging guide plate 13-3.

After the storage hopper 14-2-3 on the upper part of the flip storage box 14-2-2 is filled with a sufficient number of parts, the flip motor 14-3 drives the flip storage box 14-2-2 to rotate 180°, so that the two storage hoppers 14-2-3 are interchanged, and the parts in the upper storage hopper 14-2-3 can be rotated to the lower part for discharge, while the storage hopper 14-2-3 originally at the lower part rotates to the upper part to continue to receive the parts sent by the counting and pushing mechanism 13, so that the operation efficiency of the middle discharge mechanism 14 is higher and the middle connection is more compact. During the rotation of the flip storage box 14-2-2, the arc baffles 14-2-1 on both sides can prevent the parts from rolling out.

[0062] like Figure 8 and Fig.13As shown, in this embodiment, the packaging bag placement mechanism 22 comprises a front baffle 22-1, a rear baffle 22-2, a right baffle 22-3 and a left baffle 22-4, which are combined into a rectangular packaging bag placement cavity, and the front baffle 22-1, the rear baffle 22-2, the right baffle 22-3 and the left baffle 22-4 are all adjustable structures, which can adapt to packaging bags of different sizes by adjusting the positions of each baffle, and the front baffle 22-1, the rear baffle 22-2, the right baffle 22-3 and the left baffle 22-4 are all "L" shaped structures, and the bottoms of the front baffle 22-1 and the rear baffle 22-2 can be slightly extended to the inside of the packaging bag placement cavity for a certain distance, so as to facilitate supporting the packaging bags stacked together from the bottom. The bottom of the packaging bag placement cavity is open, and the packaging bag grabbing mechanism 23 grabs the bottommost packaging bag from the bottom opening.

When the bag feeding suction cup 23-9 is rotated to a vertical state, the first driver 23-5 and the second driver 23-7 are rotated. The actuator 23-5 extends to control the bag feeding suction cup 23-9 to contact the packaging bag, and uses the bag feeding suction cup 23-9 to suck the bottom packaging bag, then the first driver 23-5 contracts to pull the bottom packaging bag out, and the grabbing and flipping driver 23-1 drives the bag feeding suction cup 23-9 to rotate to a horizontal state again. At this time, the packaging bag is in a vertical state with the bag opening facing upward.
