The swing sorting mechanism makes the material loading plate swing, uses inertia to make the material realize preliminary positioning in the type groove, and is widely used. However, this method has certain limitations: for irregular-shaped materials with unstable center of gravity, the inertia force generated by swinging is often not enough to make the material completely fall into the bottom of the type groove or completely right in the type groove.

[0025] As Figures 1-5 Indicated, the utility model discloses a kind of based on vibration's material posture adjustment mechanism, mainly including rack 1, synchronous conveying assembly 4, load plate 2 and vibration assembly 3.

[0026] The rack 1 constitutes the main support frame of the whole mechanism, and is provided with rigid side wall plates 11 on both sides. The synchronous conveying assemblies 4 are symmetrically installed on both sides of the rack 1, for providing power and driving the load plates 2 to move intermittently. Specifically, the synchronous conveying assembly 4 comprises a conveying chain 41, a sprocket 42 for driving the conveying chain 41 to move, and a synchronous transmission shaft 43 connecting the sprockets 42 on both sides, so as to ensure the synchronous movement of the conveying chains 41 on both sides.

[0027] The load plate 2 is used for carrying and arranging materials, and is fixedly connected with the conveying chains 41 on both sides through connecting seats 23, so as to move synchronously with the chains. The load plate 2 further comprises a load plate body 21, a sliding seat 24 and a sliding block 25. The bottom surface of the load plate body 21 is fixedly connected with the sliding block 25, and the sliding block 25 is in sliding fit with the sliding seat 24 fixedly installed on the two connecting seats 23, so that the load plate body 21 can slide in the horizontal plane relative to the connecting seats 23 and the synchronous conveying assembly 4. The upper end surface of the load plate body 21 is processed with a plurality of type grooves 22 for accommodating single materials.

[0028] In order to further improve the stability during movement, support rails 44 are arranged on the inner walls of the side wall plates 11 of the rack 1, and the extension trajectories of the support rails 44 are consistent with the movement trajectories of the conveying chains 41. The side walls of the connecting seats 23 are installed with symmetrically arranged upper and lower rollers 26, the support rails 44 pass through between the upper and lower rollers 26 and form rolling fit with the rollers 26, so as to effectively guide and support the movement of the load plate 2.

[0029] The vibration assembly 3 is centrally arranged at a specific vibration station of the rack 1, for vibrating and arranging the load plate moving to the station. The vibration assembly 3 comprises a fixing seat 31, a driving cylinder 32, a connecting plate 33, an installation beam 34, a top rod 35 and a vibrator 36. The fixing seat 31 is fixedly installed on the side wall plate 11 of the rack 1, and the driving cylinder 32 is installed on the fixing seat 31. The connecting plate 33 is fixedly connected with the piston rod output end of the driving cylinder 32, the installation beam 34 is fixedly installed on the connecting plate 33, the top rod 35 is fixedly installed on the installation beam 34 and faces one side of the load plate 2, and the vibrator 36 is fixedly installed on the connecting plate 33. On the side wall plate 11 of the rack 1, a through hole 12 is formed opposite to the vibration station, and the position of the top rod 35 corresponds to the through hole 12.

[0030] As a preferred scheme of the embodiment, the load plate 2 is provided with a plurality of groups, each group is connected in series on the synchronous conveying assembly 4 through the connecting seat 23, and forms a circulating conveying. The number of the top rods 35 fixedly installed on the installation beam 34 is the same as the number of the load plate 2 in the vibration station, and the position of each top rod 35 corresponds to the end of each load plate body 21, so as to realize the synchronous processing of the whole group.

[0031] As a further optimization of the present embodiment, a gap is reserved between the two ends of the carrier plate body 21 and the wall plates 11 on both sides of the frame 1, ensuring that no interference and wear will occur during vibration. In addition, the wall plates 11 on both sides of the frame 1 are configured to have a height not less than the upper end face of the carrier plate body 21 at the vibration station, so that when the ejector rod 35 moves forward to abut against one end of the carrier plate body 21, the wall plate 11 on the other side can provide the necessary counter support for the carrier plate body 21, thereby forming an effective vibration transmission path.

[0032] Working principle: the synchronous conveying assembly 4 drives the step-by-step movement of multiple groups of carrier plates 2. When one group of carrier plates 2 moves to the vibration station and pauses, the drive cylinder 32 of the vibration assembly 3 acts to push the connecting plate 33 and mounting beam 34 to move forward, so that all the ejector rods 35 pass through the through holes 12 on the wall plates 11 and abut against the ends of the corresponding carrier plate bodies 21. Then, the vibrator 36 starts to work, and the vibration is directly transmitted to the carrier plate body 21 through the connecting plate 33, mounting beam 34 and ejector rod 35, so that the material on the carrier plate body 21 is automatically aligned to the predetermined posture in the mold groove 22 under high-frequency micro-amplitude vibration. After the vibration is completed, the drive cylinder 32 retracts, the ejector rod 35 is separated from the carrier plate body 21, and the synchronous conveying assembly 4 is started again to move the carrier plate group with completed material out of the station, while the next group of carrier plates to be aligned is sent in, and the cycle operation is repeated.

Therefore, it is to be understood that the application is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended 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.
