For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Example 1 An automatic blank loading gripper includes a gripper body, a suction cup assembly, a push-pull mechanism, and a hook-and-cutter assembly. The suction cup assembly is disposed on the lower end face of the gripper body, the slider assembly is slidably disposed on the gripper body, the hook-and-cutter assembly is disposed on the slider assembly, and the slider assembly is connected to the push-pull mechanism, which is disposed on the gripper body and is used to drive the slider assembly to move back and forth.

[0024] Furthermore, there are two sets of hook-and-cutter assemblies and two sets of slider assemblies. The two slider assemblies are symmetrically arranged on the gripper body, and the two sets of hook-and-cutter assemblies are respectively arranged on the two slider assemblies. The two sets of hook-and-cutter assemblies are also relatively symmetrically arranged. The slider assembly includes a slider 3-2, and a guide rod 2-6 is arranged longitudinally on the gripper body. The slider is set on the guide rod and is connected to a push-pull mechanism. The push-pull mechanism drives the slider to move back and forth along the guide rod.

[0025] Furthermore, the slider assembly and the hook-and-cutter assembly are arranged on the centerline of the gripper body; The suction cup assembly includes multiple vacuum suction cups mounted on the gripper body. The multiple vacuum suction cups are divided into two groups and are symmetrically arranged on both sides of the centerline where the slider assembly and hook-and-cutter assembly are located on the gripper body.

[0026] Furthermore, the push-pull mechanism includes an ejector cylinder, which is mounted on the gripper body. The movable end of the ejector cylinder is connected to the slider of the slider assembly. The ejector cylinder can drive the slider to move back and forth along the guide rod.

[0027] Example 2 Based on Example 1, the hook and strip cutter assembly is further defined, resulting in Example 2 having even better performance.

[0028] The hook and strap cutter assembly includes a cutter pressure plate cylinder 3-1, a pressure plate 3-3, a hook and strap plate 3-4, and a cutter 3-5. The hook and strap plate 3-4 is horizontally mounted on the slider assembly along the longitudinal direction. The cutter pressure plate cylinder is vertically mounted on the slider of the slider assembly. The pressure plate is connected to the movable end of the cutter pressure plate cylinder and is positioned directly above the hook and strap plate. The cutter is positioned on one side of the pressure plate and is fixedly connected to the pressure plate. The cutter is staggered from the hook and strap plate below. When the cutter pressure plate cylinder extends, it drives the cutter and the pressure plate to move towards the hook and strap plate. The pressure plate presses down on the strapping on the hook and strap plate, while the cutter moves down to cut the strapping from one side of the hook and strap plate. When the cutter pressure plate cylinder retracts, it drives the cutter and the pressure plate to move upward towards the hook and strap plate, and the pressure plate disengages from the hook and strap plate.

[0029] Furthermore, a protective plate 3-6 is provided on one side of the cutter, and the protective plate is connected to the slider assembly.

[0030] Furthermore, the slider assembly is equipped with cable tie detection photoelectric sensor 3-8, which is used to detect whether there is a cable tie on the hook plate (that is, to detect whether the hook plate has successfully hooked the cable tie).

[0031] Furthermore, the cable tie detection photoelectric sensor is mounted on the slider assembly via the detection bracket 3-7, and the cable tie detection photoelectric sensor 3-8 is mounted above the hook plate; a vision camera is mounted on the gripper body or on an independent bracket above the working area.

[0032] Furthermore, slider 3-2 is directly fitted onto a pair of guide rods 2-6, and the tail sections of a pair of ejector cylinders 1-6 are respectively fitted onto ejector cylinder tailstocks 1-7, equipped with nuts for locking and limiting. The heads are mounted on slider 3-2 via their own pins. Hook plates 3-4 are bolted to the bottom of slider 3-2. When ejector cylinders 1-6 extend, hook plates 3-4 can hook the strapping tape. During the strapping tape hooking process, the strapping tape detection photoelectric sensor 3-8, bolted to the detection bracket 3-7, will detect the strapping tape and send a success signal to the control system. If no signal is received, it indicates that the strapping tape hooking has failed, and the system completes the transfer and rejection of the entire bundle of blanks. A protective plate 3-6, bolted to the side of slider 3-2, provides safety protection when the cutter 3-5 extends. The cutter pressure plate cylinder 3-1 is bolted to the slider 3-2, and the bottom is bolted to the pressure plate 3-3. The cutter 3-5 is also bolted to the side of the pressure plate 3-3. When the cutter pressure plate cylinder 3-1 extends, the cutter 3-5 cuts the strapping that has been hooked on the hook plate 3-4 and clamps one end of the strapping. Driven by the robot, the strapping can be pulled out and placed into the designated recycling station.

[0033] Furthermore, the outer ring of the gripper body is provided with a collision safety frame 1-11, which is connected to the gripper body by a strong magnet 1-10. A collision switch 1-1 is connected between the gripper body and the collision safety frame. The collision safety frame 1-11 and the collision switch 1-1 connected thereto serve as safety components.

[0034] Furthermore, the gripper body includes a body frame and a gripper flange for connecting to the robot body. The body frame includes two gripper longitudinal beams 1-4 and a gripper crossbeam 2-3. The two ends of the gripper crossbeam are respectively connected to the middle of the two gripper longitudinal beams 1-4. The gripper flange is set on the gripper crossbeam. A guide rod connecting plate 2-5 is connected between the two ends of the two gripper longitudinal beams. The slider assembly includes a slider, a guide rod on the main frame, the slider being mounted on the guide rod and able to move back and forth along the guide rod, the guide rod being arranged longitudinally between two gripper beams, and the two ends of the guide rod being connected to the guide rod connecting plates at both ends respectively.

[0035] Furthermore, there are two guide rods, and a guide rod pressure plate 2-2 is connected between the middle of the two guide rods. The guide rod pressure plate is connected to the gripper beam.

[0036] Furthermore, some vacuum suction cups are directly connected to the main frame, while others are connected to the main frame via an extension bracket. The extension bracket helps to avoid other components, allowing the vacuum suction cups to be distributed throughout the body and ensuring a more even distribution of force during gripping.

[0037] An automatic box-loading robot includes an automatic box-loading gripper, a control system, and a robot body. The robot body is connected to the gripper body of the automatic box-loading gripper via a gripper flange. A vision camera is provided on the gripper body or above the working area. The control system is connected to the robot body, the automatic box-loading gripper, and the vision camera.

[0038] The control system is connected to the suction cup assembly, push-pull mechanism, hook and cable cutter assembly, and cable tie detection photoelectric sensor.

[0039] The gripper body is equipped with a vision camera or an independent bracket above the working area. The vision camera is used to acquire images and identify and determine the box blank and its position in the image.

[0040] The working process of this utility model is as follows: Step 1: The robot body drives the automatic box-loading gripper to move to the storage area for the whole bundle of box blanks; Step 2: Identify the specific location of the entire bundle of blanks using a vision camera; Step 3: A whole bundle of box blanks is gripped by the suction cup assembly. The push-pull mechanism drives the hook and cutter assembly to move through the slider assembly to hook the strapping on the whole bundle of box blanks. The photoelectric sensor determines whether the strapping has been hooked. Step 4: After moving the grabbed bundle of box blanks to the designated position on the box opener, the strapping is cut by the hook and cutter assembly, and the cut strapping is clamped and moved to the strapping recycling point.

[0041] The working principle of this utility model: like Figure 4 As shown, the automatic box blank loading gripper is mounted on the articulated robot via gripper flange 1-3. A vacuum source is connected to the first and second vacuum interfaces via vacuum pipes. Ten suction cups are used to grip the entire bundle of box blanks. Compressed air via a solenoid valve is connected to the ejector cylinder 1-6 and the cutter pressure plate cylinder 3-1 via air pipes. The ejector cylinder 1-6 extends during its stroke to hook the strapping tape, while the cutter pressure plate cylinder extends to cut the strapping tape and clamp one end of the cut tape. Successful hooking is detected during the strapping tape hooking process. When the automatic box blank loading gripper works in conjunction with a vision camera, it can accurately position the gripper, determine the orientation of the box blank, judge the box blank specifications, and determine the position of the strapping tape. It can also reject non-compliant box blanks, ensuring the stability of the gripper's gripping and the effectiveness of the automatic box blank loading.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the automatic blank loading gripper of this utility model comprises, but is not limited to, a pair of collision switches 1-1, a pair of switch brackets 1-2, gripper flanges 1-3, a pair of gripper longitudinal beams 1-4, four extension brackets 1-5, a pair of ejection cylinders 1-6, a pair of ejection cylinder tailstocks 1-7, four transition vacuum tube structures 1-8, four safety frame brackets 1-9, four powerful magnets 1-10, collision safety frame 1-11, a pair of vacuum inlet pipe connectors 1-12, vacuum pipes 1-13, ten vacuum suction cups 2-1, guide rod pressure plates 2-2, gripper crossbeams 2-3, air blowing connectors 2-4, a pair of guide rod connecting plates 2-5, a pair of guide rods 2-6, a pair of cutter pressure plate cylinders 3-1, a pair of sliders 3-2, a pair of pressure plates 3-3, a pair of hook plates 3-4, a pair of cutters 3-5, a pair of protective plates 3-6, a pair of detection brackets 3-7, and a pair of cable tie detection photoelectric eyes 3-8.

[0043] The main body comprises a gripper flange 1-3, a pair of gripper longitudinal beams 1-4, a guide rod pressure plate 2-2, a gripper crossbeam 2-3, a pair of guide rod connecting plates 2-5, and a pair of guide rods 2-6. The gripper flange 1-3 is directly fixed to the gripper crossbeam 2-3 with bolts for connecting the gripper to the robot. The two ends of the pair of guide rods 2-6 are fixed to the pair of guide rod connecting plates 2-5 with bolts, and the middle is pressed against the gripper crossbeam 2-3 by the guide rod pressure plate 2-2 and locked with bolts. The two ends of the pair of guide rod connecting plates 2-5 are respectively fixed to the two ends of the pair of gripper longitudinal beams 1-4 with bolts, forming a structurally stable gripper main body assembly.

[0044] The suction cup assembly includes four vacuum suction cups 2-1 at both ends, which are directly locked onto four extension brackets 1-5 by nuts. The four extension brackets 1-5 are respectively fixed to the outer sides of the two gripper longitudinal beams 1-4 by bolts to expand the position of the vacuum suction cups. There are six vacuum suction cups 2-1 in the middle position, in groups of three, which are installed on the lower side of the two gripper longitudinal beams 1-4. The outer suction cups are connected to each other by vacuum pipes 1-13. The external vacuum source is connected to a pair of gripper longitudinal beams 1-4 with hollow structure through a pair of vacuum inlet pipe connectors 1-12 to ensure vacuum conduction of all vacuum suction cups of the gripper, so as to grasp the bundled box blanks.

[0045] The safety components include a pair of collision switches 1-1, which are bolted to the collision safety frame 1-11 and one of the gripper beams 1-4 via a pair of switch brackets 1-2. Four powerful magnets 1-10 are bolted to the collision safety frame 1-11. Four safety frame brackets 1-9 are bolted to the pair of gripper beams 1-4 and are attracted to the safety frame brackets 1-9 by the powerful magnets 1-10, thus connecting the collision safety frame 1-11 to the gripper. When the robot drives the gripper and encounters an obstacle, the collision safety frame 1-11 will shift relative to the gripper body. At this time, the collision switches 1-1 will send an alarm signal to the control system.

[0046] The slider assembly consists of a pair of cutting and pressing cylinders 3-1, a pair of sliders 3-2, a pair of pressing plates 3-3, a pair of hook plates 3-4, a pair of cutters 3-5, a pair of protective plates 3-6, a pair of detection brackets 3-7, and a pair of cable tie detection photoelectric sensors 3-8. Slider 3-2 is directly fitted onto a pair of guide rods 2-6. The tail sections of the pair of ejection cylinders 1-6 are respectively fitted onto ejection cylinder tail seats 1-7, with nuts for locking and limiting. The heads are mounted on slider 3-2 via their own pins. Hook plates 3-4 are bolted to the bottom of the sliders. When the ejection cylinders 1-6 extend, the hook plates 3-4 can hook the cable ties. During the hooking process, the cable tie detection photoelectric sensors 3-8, bolted to the detection brackets 3-7, will detect the cable tie and send a success signal to the control system. If no signal is received, it indicates that the hooking of the cable tie has failed, and the system completes the transfer and rejection of the entire bundle of blanks. A protective plate 3-6, bolted to the side of the slider 3-2, provides safety protection when the cutter 3-5 extends. A cutter pressure plate cylinder 3-1, bolted to the slider 3-2, has a pressure plate 3-3 bolted to its bottom. The cutter 3-5 is also bolted to the side of the pressure plate 3-3. When the cutter pressure plate cylinder 3-1 extends, the cutter 3-5 cuts the strapping already hooked on the hook plate 3-4 and clamps one end of the strapping. Driven by the robot, the strapping can be pulled out and placed into the designated recycling station.

[0047] In summary: 1. The gripper body is lightweight and has a universal interface, allowing it to be mounted on various articulated robots by matching different flange interfaces; 2.
