[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4A palletizing composite fixture for boxed products with interlayer partitions is provided, comprising a fixture frame 1; a fixed clamping plate 2 fixed to the fixture frame 1; and a movable clamping plate 3 configured to reciprocate linearly towards and away from the fixed clamping plate 2, with a gripping claw 4 mounted on its lower part. The lower part of the gripping claw 4 is bent towards the fixed clamping plate 2 to form a bent portion 401. The fixture frame 1 is mounted on a palletizing robot and moves under the robot's drive to grip and palletize boxed products. The movable clamping plate 3, driven by a power mechanism, moves laterally left and right, i.e., makes linear movements towards and away from the fixed clamping plate 2. When a boxed product needs to be gripped, the fixture moves to the product, with the bent portion 401 of the gripping claw 4 positioned below the boxed product. Then, the movable clamping plate 3 moves towards the fixed clamping plate 2, with the bent portion 401 moving to the bottom of the boxed product to grip it firmly. The feature is that it further includes at least two rotating shafts 5 rotatably mounted on the clamp frame 1. At least one retractable long arm 6 is mounted on each rotating shaft 5. One end of the retractable long arm 6 is fixed to the rotating shaft 5, and the other end is fixedly equipped with a suction cup 7. A rotary drive device is connected to the rotating shaft 5 to drive its rotation. The rotation of the rotating shaft drives the free end of the retractable long arm 6 to rotate the suction cup 7 between the working position and the retraction position. When the suction cup 7 is in the working position, it is located below the fixed clamping plate 2. When the clamp needs to pick up boxed products, the rotating shaft 5 drives the retractable long arm 6 to rotate to the retraction position and fix it. When the suction cup 7 needs to pick up a partition, the rotating shaft 5 rotates, driving the retractable long arm 6 to move to the working position and fix it. At this time, the suction cup 7 is located below the bent portion 401. Thus, when the suction cup 7 picks up a partition, the fixed clamping plate 2 and the moving clamping plate 3 will not interfere with the suction cup 7. When suction cup 7 rotates to the partition, the palletizing robot drives suction cup 7 to press down on the partition, expelling the air inside suction cup 7 to create negative pressure, thus sucking up the partition. Then, driven by the palletizing robot, it moves to the neatly stacked boxed products that need to be added with partitions.

[0016] The rotary drive device includes a long-arm drive cylinder 8 mounted on the clamp frame 1. The bottom of the long-arm drive cylinder 8 is rotatably connected to the clamp frame 1. The telescopic rod of the long-arm drive cylinder 8 is rotatably connected to a rotating connector 9, which is fixedly connected to the rotating shaft 5. When the long-arm drive cylinder 8 extends, it drives the retractable long arm 6 to move to the working position. At this time, the retractable long arm 6 and the fixed clamping plate 2 are in a vertical direction, and then the partition can be picked up and placed on the stacked goods. Then, the long-arm drive cylinder 8 retracts, causing the suction cup 7 to deflect. Air enters the suction cup 7, allowing it to detach from the partition. When the long-arm drive cylinder 8 retracts, it drives the rotating connector 9 to rotate, which in turn drives the rotating shaft 5 to rotate, thereby driving the retractable long arm 6 to rotate to the recovery position. Then, it can pick up boxed products without interference between the retractable long arm 6 and the suction cup 7 affecting the gripping of goods.

[0017] There are two rotating shafts 5. One rotating shaft 5 is located on the side of the fixed clamping plate 2 away from the movable clamping plate 3, and the other is located on the side of the movable clamping plate 3 away from the fixed clamping plate 2. The two rotating shafts 5 are parallel and rotate in opposite directions.

[0018] Both ends of the rotating shaft 5 are fixedly connected to a retractable long arm 6. Since there are two rotating shafts 5 located on both sides of the clamp, there are four retractable long arms 6, each with a suction cup 7 fixed to its free end. This creates four gripping points during partition gripping, ensuring stable and reliable gripping of the partition. When the partition is moved onto the stacked goods and needs to be released, the long arm drive cylinder 8 retracts, causing the rotating shaft 5 to rotate. This causes the retractable long arms 6 connected to the two rotating shafts 5 to move towards each other, i.e., deflect towards the center of the clamp. The forces generated by the deflection of the suction cups 7 are opposite to each other, effectively preventing the partition from moving due to the deflection of the suction cups 7. When the retractable long arm 6 deflects the suction cups, air enters between the suction cups 7 and the partition, causing the suction cups to detach from the partition.

[0019] A guide rail assembly is fixed on the clamp frame 1. The guide rail assembly includes a fixed guide rail 10 fixed on the clamp frame 1 and a guide block 11 fixedly installed on the movable clamping plate 3. The guide block 11 is installed on the fixed guide rail 10 and slidably connected to the fixed guide rail 10. A clamping plate cylinder 12 is installed on the clamp frame 1. The telescopic rod of the clamping plate cylinder 12 is fixedly connected to the movable clamping plate 3. There are two fixed guide rails 10, and the clamping plate cylinder 12 is located between the two fixed guide rails 10. The guide rail assembly restricts the movable clamping plate 3 to only make linear movements towards and away from the fixed clamping plate 2. Driven by the clamping plate cylinder 12, it can make reciprocating linear movements. When the clamping plate cylinder 12 extends, it drives the movable clamping plate 3 away from the fixed clamping plate 2. When the clamping plate cylinder 12 retracts, it drives the movable clamping plate 3 towards the fixed clamping plate 2 to clamp the boxed products.

[0020] The upper end of the gripper 4 is rotatably connected to the movable clamping plate 3. A gripper cylinder 13 is connected to the movable clamping plate 3. The bottom of the gripper cylinder 13 is rotatably connected to the movable clamping plate 3. The telescopic rod of the gripper cylinder 13 is rotatably connected to the gripper 4. The connection part between the telescopic rod of the gripper cylinder 13 and the gripper 4 is located on the side of the gripper 4 away from the fixed clamping plate 2, and the connection part is located in the middle of the gripper 4. The gripper 4 is rotatably connected to the movable clamping plate 3. When gripping goods, the gripper cylinder 13 extends, driving the gripper 4 to move into the gripping state. At this time, the bent part 401 of the gripper 4 is perpendicular to the movable clamping plate 3, which makes the gripping of goods stable and reliable. When it is necessary to release the gripped goods, the gripper cylinder 13 retracts, and the gripper 4 moves away from the fixed clamping plate 2. At the same time, the clamping plate cylinder 12 drives the movable clamping plate 3 to move away from the fixed clamping plate 2, releasing the goods in the designated area and stacking the goods, making the release of goods easier.

[0021] The beneficial effects of this utility model are: it can grip and hold partitions while simultaneously palletizing boxed goods, improving palletizing stability; it integrates the functions of a palletizing robot, increasing production efficiency and reducing labor costs; it uses suction cups to pick up and release partitions, and the rotation of the retractable arm drives the suction cups to retract, preventing interference with the gripping of goods; the structure is simple and the manufacturing cost is low; when the suction cups deflect to release the partitions, the deflection forces generated by the suction cups corresponding to different rotating axes are relative and cancel each other out, effectively preventing partition movement during this process.

[0022] The embodiments described above are not intended to limit the scope of this utility model. Any modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the design concept of this utility model should be included within the protection scope defined by the claims of this utility model.
