[0030] The limiting assembly is the key to ensure the stable placement of the product 6 in the rotating plate 5. It includes two groups of sliding grooves 52 opened on the upper and lower surfaces of the rotating plate 5, and the sliding grooves 52 are slidably provided with clamping blocks 53. The upper surfaces of the two groups of clamping blocks 53 are respectively connected with a first supporting plate 51 and a second supporting plate 60 through bolts, and the two are slidably provided on the surface of the rotating plate 5 through guide rail sliding blocks to ensure the smoothness of movement.

A floating head 71 is fixedly mounted on the output end of the second cylinder 7, and a connecting bracket 72 is welded to the floating head 71. The connecting bracket 72 is bolted to one side of the first rotating frame 2. When the second cylinder 7 is driven, the first rotating frame 2 is driven to slide on the guide rail through the transmission of the floating head 71 and the connecting bracket 72, achieving flexible position adjustment.

[0036] To ensure stability during the flipping process, a small rotating shaft 31 is rotatably mounted inside the second rotating frame 3 via bearings. An adapter plate 23 is bolted to one end of the small rotating shaft 31. The other end of the small rotating shaft 31 is bolted to a limit arm 32, and the outer side of the second rotating frame 3 is bolted to a limit screw seat 33. The top of the limit screw seat 33 is threaded with two flipping limit screws 34 that cooperate with the limit arm 32. When the small rotating shaft 31 rotates, the limit arm 32 rotates accordingly. When it contacts the flipping limit screws 34, it reaches the limit position of the flipping, thus achieving precise limiting of the rotation angle of the small rotating shaft 31.

[0037] The initial state, under the action of the rotating cylinder 21 rotating the driving cylinder, one side of the rotating plate 5 faces upward, and under the action of the two groups of springs 55, the upper and lower groups of the first supporting plates 51 and the second supporting plates 60 are in the closed state and inward. Before the product 6 is put in, under the extension of the two first cylinders 4, the driving unlocking head 41 moves to drive the two unlocking swing arms 58 located above to rotate on the corresponding rotating pins 56, and in the rotating process, the second waist-shaped hole 581 and the driving pin 59 drive the corresponding first supporting plate 51 and the second supporting plate 60 to move outward, after the product 6 is put in, the two first cylinders 4 retract, and under the action of the spring 55, the upper first supporting plate 51 and the second supporting plate 60 are close to each other again and closed, and in the closing process, the lower first supporting plate 51 and the second supporting plate 60 fix the product 6;

[0038] Then the rotating cylinder 21 reverses the movement, can drive the large rotating shaft 22 to rotate, the large rotating shaft 22 rotates can drive the rotating plate 5 to overturn 180° through the adapter plate 23, in the overturning process, the product 6 is supported by the upper and lower groups of the clamping blocks 53, and the product 6 can be stably positioned in the mechanism under the hoop of the rotating plate 5;

[0039] After the overturning is in place, the two first cylinders 4 extend again, and this time the two unlocking swing arms 58 drive the first supporting plate 51 and the second supporting plate 60 on the other side to open, and after the product 6 is grabbed, it returns to the original position.

[0040] However, as known to those skilled in the art, the working principle and wiring method of the first cylinder 4, the second cylinder 7 and the rotating cylinder 21 are common, which belong to conventional means or common knowledge, and will not be repeated here, and those skilled in the art can make any selection or arrangement according to their needs or convenience.

[0041] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the technical field can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
