Description

Technical Field

[0001] This utility model relates to the field of box opening device technology, specifically a robot multi-box box opening device that does not require adjustment. Background Technology

[0002] Cardboard box packaging is an indispensable part of modern logistics, bearing the important responsibilities of containing, protecting, and aesthetically pleasing products. Currently, cardboard box operations are mostly carried out manually or by automatic opening devices to complete the integrated process of picking up the cardboard, forming, folding the lid, and sealing the bottom.

[0003] Existing automatic carton opening devices are mostly dedicated carton opening equipment. During use, due to their limited applicability to cartons, they require a significant amount of manual operation. Every time the carton size is changed, the automatic carton opening device needs to readjust the opening gripper mechanism. Skilled operators may take at least ten minutes, and some may even need half an hour, to adjust the opening gripper mechanism. This excessive time consumption is inconvenient for fast-paced automated production processes and fails to meet the current customer demand for universal and intelligent carton opening. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a robotic multi-box unloading device that eliminates the need for adjustment. Through the coordinated arrangement of a mounting plate, a positioning top plate, a cylinder assembly, a bending assembly, a rotating assembly, and a suction assembly, it enables the unloading of all specified box types with a single adjustment, eliminating the need for manual adjustment. This saves time and effort, is highly efficient, and makes unloading intelligent and universal.

[0005] To achieve the above objectives, this utility model provides a robotic multi-box box opening device without adjustment, including an opening gripper mechanism, a robot, a carton forming mechanism, a conveyor belt, and a cardboard hopper; the opening gripper mechanism is provided with a mounting flange plate, and a flange connection seat is provided on the mounting flange plate; the flange connection seat is connected to the robot's wrist;

[0006] Furthermore, the unpacking gripper mechanism also includes a mounting plate, a positioning top plate, a cylinder assembly, a bending assembly, a rotating assembly, and a suction assembly; the mounting flange plate, mounting plate, and positioning top plate are arranged sequentially; one end of the mounting plate is rotatably connected to a mounting side plate; one end of the positioning top plate is rotatably connected to a positioning top side plate, and the mounting side plate and the positioning top side plate are on the same side; a cylinder assembly is arranged above the mounting plate, and a bending assembly is rotatably connected to the head of the cylinder assembly; a rotating assembly is arranged below the notch at one end of the mounting plate, and a protrusion is provided on the mounting side plate near the notch, the protrusion and the notch can be spliced ​​to form a plane; a suction assembly is movably mounted on the end faces of the positioning top plate and the positioning top side plate.

[0007] This invention utilizes a coordinated setup of an installation plate, a top plate, a cylinder assembly, a bending assembly, a rotating assembly, and a suction assembly. When the robot wrist controls the opening gripper mechanism to pick up cardboard from the cardboard hopper, the cylinder assembly retracts. The bending assembly, under the rotation of the rotating assembly, drives the installation side plate and the top plate upwards. At this point, the installation plate, installation side plate, top plate, and top plate are all on the same horizontal line, with the top plate in its initial state. The suction assembly then picks up the cardboard. After the cardboard is picked up, the opening gripper mechanism straightens it into place. The cylinder assembly extends, and the bending assembly drives the installation side plate and the top plate downwards, changing the top plate from its initial state to a side-opening state. After the cardboard is straightened, it is sent to the carton forming mechanism for folding and sealing, and finally to the conveyor belt. This allows for the completion of opening operations for all specified carton types with a single adjustment, eliminating the need for manual adjustment and saving time and effort while maintaining high efficiency.

[0008] Furthermore, an extension plate is fixedly connected to the top side plate at the end furthest from the bending component; a connecting plate is provided between the top side plate and the extension plate. By providing the extension plate, the box-opening gripper mechanism can pick up large-format cardboard, realizing box-opening operations without adjustment for multiple box types.

[0009] Furthermore, the cylinder assembly includes a cylinder body and a piston rod; the end of the cylinder body is fixedly mounted on a cylinder mounting base; a retractable piston rod is provided on the cylinder body at the end away from the cylinder mounting base, and a Y-shaped connector is provided at the head of the piston rod; the Y-shaped connector is rotatably connected to the bending assembly. By providing a Y-shaped connector at the head of the piston rod, the piston rod retracts and extends, driving the bending assembly to move through the Y-shaped connector, thereby changing the initial state and the side-blowing state, realizing the cardboard suction and straightening operation.

[0010] Furthermore, the bending assembly includes a bending plate, a fixing plate, and a connecting pin; one end of the bending plate is embedded in the Y-shaped connector; a through hole is provided at the end of the bending plate, and the connecting pin passes through the Y-shaped connector and the through hole; the bending plate at the end away from the Y-shaped connector is fixed to the mounting side plate by the fixing plate. Through the bending assembly, the cylinder assembly can drive the mounting side plate and the top side plate to move up and down along the bending plate, realizing the suction and alignment of the cardboard.

[0011] Further, the rotating assembly includes a rotating shaft, shaft retaining rings, and locking plates; the rotating shaft is rotatably mounted on the bottom of the mounting plate; several shaft retaining rings are sleeved on the rotating shaft; several locking plates pass through the shaft retaining rings; the end faces of the locking plates located at both ends of the rotating shaft are fixed to the bottom of the mounting plate, and the end face of the locking plate located in the middle of the rotating shaft is fixed to the bottom of the mounting side plate; a first limiting block is also provided at the bottom of the mounting plate; a second limiting block is provided at the end face of the top plate. When the piston rod retracts, the rotating shaft rotates counterclockwise, causing the bending assembly to move upward. The mounting side plate and the top plate rotate upward under the action of the bending assembly. When the mounting side plate abuts against the first limiting block, the rotating shaft stops rotating, and the mounting side plate and the top plate are in their initial state. When the piston rod extends, the rotating shaft rotates clockwise, causing the bending assembly to move downward. During the downward rotation, the mounting side plate abuts against the second limiting block, the rotating shaft stops rotating, and the mounting side plate and the top plate change from their initial state to a side-opening state.

[0012] Furthermore, the suction assembly is equipped with a vacuum suction cup; the bottom surface of the vacuum suction cup is provided with a suction surface; the vacuum suction cup includes a first suction cup, a second suction cup, and a third suction cup; a set of first suction cups passes through the end face of the top plate, and a set of third suction cups also passes through the end face of the top plate away from the side plate; a set of second suction cups passes through the end face of the side plate. When the vacuum suction cup picks up the cardboard, the cardboard is tightly attached to the end faces of the top plate and the side plate. The vacuum suction cup uses negative pressure to pick up the cardboard, and the suction surface is flush with the end faces of the top plate and the side plate to ensure good airtightness, allowing the cardboard to be smoothly picked up by the vacuum suction cup. When picking up small-sized cardboard, the first and second suction cups work together; when picking up large-sized cardboard, the first, second, and third suction cups work together.

[0013] Furthermore, one set of the first suction cups has four or more; one set of the second suction cups has four or more; and one set of the third suction cups has two or more. By setting multiple suction cups, the cardboard can be picked up from all directions, ensuring that the cardboard is picked up and aligned smoothly.

[0014] Furthermore, the suction assembly is also equipped with a vacuum generator, which is located at the bottom of the mounting flange plate. The vacuum generator includes a second vacuum generator, a first vacuum generator, and a third vacuum generator arranged sequentially. The first vacuum generator controls the first suction cup, the second vacuum generator controls the second suction cup, and the third vacuum generator controls the third suction cup. The first, second, and third vacuum generators independently control the first, second, and third suction cups, respectively. When suctioning small-sized cardboard, only the first and second vacuum generators need to be turned on; when suctioning large-sized cardboard, all three vacuum generators are turned on, enabling adjustment-free opening of multiple types of boxes and improving production efficiency.

[0015] Furthermore, the carton forming mechanism includes a compaction zone and a sealing zone; the compaction zone is provided with a curved chute, and push plates are arranged opposite each other on both sides of the curved chute; a dual-axis cylinder is provided at the bottom of each of the two push plates. The robot delivers the neatly positioned cardboard to the compaction zone through the carton opening gripper mechanism. The carton forming mechanism, through the curved chute and in coordination with the robot's movements, compacts the front and rear folding panels of the carton inward. Then, the robot pushes the carton onto the push plates, and the dual-axis cylinders extend and retract to bring the left and right folding panels together inward to form a complete bottom of the carton. The robot continues to push the carton forward to the sealing zone to complete the sealing operation.

[0016] Furthermore, the cardboard hopper includes a fixed frame with a slide rail; a crossbar is positioned above the front of the slide rail, and a positioning block is fitted onto the crossbar; a tapered pull block is bolted to the outside of the positioning block; and a gravity pressure plate is fixedly connected to the rear of the slide rail. The slide rail can be used to stack cardboard, the positioning block can position the cardboard folding board within the slide rail, the tapered pull block facilitates the opening gripper mechanism to quickly pick up and separate the cardboard, and the gravity pressure plate uses its weight to press against the rear of the stacked cardboard. After the robot completes one opening operation, the cardboard moves forward along the slide rail, maintaining a supply.

[0017] Furthermore, the cardboard hopper is equipped with a large hopper and a small hopper. The cardboard hopper can be customized according to the actual cardboard specifications, with the large hopper and small hopper respectively used for stacking large-specification cardboard and small-specification cardboard. The box-opening device can be equipped with multiple cardboard hoppers. After the initial debugging, the box-opening gripper mechanism requires no further debugging. The box-opening operation is simple and efficient. When changing cardboard specifications, only the corresponding cardboard hopper needs to be replaced.

[0018] Furthermore, a solenoid valve is installed on the top of the mounting flange plate. The solenoid valve controls the on / off state and flow direction of the airflow inside the cylinder assembly through electromagnetic induction, thereby controlling the extension and retraction of the piston rod.

[0019] Furthermore, the mounting flange plate and the mounting plate are fixedly connected by a set of first support rods; the mounting plate and the top plate, and the mounting side plate and the top side plate are fixedly connected by a set of second support rods.
