Description

Technical Field

[0001] This utility model relates to the field of robot equipment technology, and in particular to a small logistics palletizing robot. Background Technology

[0002] With the rapid development of the logistics industry, palletizing operations, as a key link in material handling, have created an increasingly urgent need for automated equipment. Small palletizing robots, with their small size and flexible operation, are widely used in small and medium-sized warehousing and logistics scenarios.

[0003] A smart palletizing robot with Chinese patent number CN202272514U includes a base, a waist rotating assembly mounted on the base, a frame fixed to the waist rotating assembly, a main arm, a main forearm, a telescopic auxiliary arm, a telescopic auxiliary forearm, and a gripper mechanism. The control circuits on the waist rotating assembly, the telescopic auxiliary arm, the telescopic auxiliary forearm, and the gripper mechanism are connected to a CNC computer via data cables. It can simultaneously handle multiple materials and palletize multiple stacks, and complete various tasks such as loading, unloading, transporting, palletizing, and depalletizing of various packaging types such as bags and boxes. The palletizing robot has a small footprint, simple structure, and high flexibility, which greatly reduces the intensity of manual labor and improves production efficiency.

[0004] Traditional palletizing robots often use a unified start-stop control logic for their negative pressure suction heads. Once the entire suction module is started, all negative pressure suction heads are in working condition. However, in actual palletizing operations, materials vary in size and shape, and some negative pressure suction heads often do not come into contact with the materials. The continuous operation of these idle suction heads not only causes unnecessary energy consumption but also keeps the energy cost of the equipment high for long-term operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a small logistics palletizing robot, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a small logistics palletizing robot, including a base, an electromechanical arm fixedly connected to the upper end of the base, an adsorption block installed at the output end of the electromechanical arm, a plurality of evenly distributed cylindrical inner holes at the lower end of the adsorption block, a hollow outer cylinder fixedly connected to the inner end of the cylindrical inner hole, an inner top plate fixedly connected to the upper inner wall of the hollow outer cylinder, a contact sensor fixedly connected to the lower middle part of the inner top plate, an inner sliding column slidably connected to the inner end of the hollow outer cylinder, a negative pressure suction head fixedly connected to the lower end of the inner sliding column, a protruding contact block fixedly connected to the upper end of the inner sliding column, a vertical spring fixedly connected between the protruding contact block and the inner top plate, and intermittent contact between the protruding contact block and the contact sensor.

[0007] As a further technical solution of this utility model, the outer end of the inner sliding column is fixedly connected with multiple sliding outer blocks, and the outer end of the hollow outer cylinder is provided with multiple vertical outer sliding grooves.

[0008] As a further technical solution of this utility model, the inner sliding column and the hollow outer cylinder are slidably connected by corresponding vertical outer sliding grooves and sliding outer blocks, and the front end of the equipment base is equipped with a material conveying rolling belt.

[0009] As a further technical solution of this utility model, a supporting top frame is fixedly connected to the upper end of the equipment base, and multiple elastic spheres are fixedly connected to the upper end of the supporting top frame.

[0010] As a further technical solution of this utility model, a top horizontal plate is fixedly connected to the upper end of multiple elastic spheres, and a protruding brush strip is fixedly connected to the upper end of the top horizontal plate.

[0011] As a further technical solution of this utility model, the protruding brush strip and multiple negative pressure suction heads are in intermittent contact with each other, and a transverse electrical guide rail is fixedly connected to the upper end of the equipment base.

[0012] As a further technical solution of this utility model, the output end of the transverse electric guide rail and the electric robotic arm are connected to each other, and the adsorption block moves and displaces above the conveying rolling belt.

[0013] This utility model provides a small logistics palletizing robot, which has the following advantages compared with the prior art:

[0014] This small logistics palletizing robot features an intelligent linkage design between a negative pressure suction head and a contact sensor. When the suction block moves down close to the material, only the negative pressure suction head in contact with the material will activate after the contact sensor triggers a signal, while the suction heads not in contact with the material remain closed. This avoids unnecessary energy consumption at the source and effectively reduces energy costs for long-term operation. Simultaneously, during palletizing gaps, when the horizontal electric guide rail moves the suction block above the support top frame, the protruding brush strip on the top horizontal plate can generate relative friction with the negative pressure suction head, automatically removing residual dust or material debris from the suction head surface. This ensures the sealing and firmness during subsequent suction, guaranteeing operational stability. The accompanying elastic ball forms a flexible buffer when the suction head and brush strip come into contact, significantly reducing impact force and preventing damage to the suction head and brush strip caused by hard collisions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a small logistics palletizing robot: it includes a device base 1, an electromechanical arm 4 fixedly connected to the upper end of the device base 1, an adsorption block 3 installed at the output end of the electromechanical arm 4, a plurality of evenly distributed cylindrical inner holes 6 opened at the lower end of the adsorption block 3, a hollow outer cylinder 7 fixedly connected to the inner end of the cylindrical inner hole 6, an inner top plate 9 fixedly connected to the upper inner wall of the hollow outer cylinder 7, a contact sensor 10 fixedly connected to the lower middle part of the inner top plate 9, an inner sliding column 8 slidably connected to the inner end of the hollow outer cylinder 7, a negative pressure suction head 5 fixedly connected to the lower end of the inner sliding column 8, a protruding contact block 12 fixedly connected to the upper end of the inner sliding column 8, a vertical spring 11 fixedly connected between the protruding contact block 12 and the inner top plate 9, and intermittent contact between the protruding contact block 12 and the contact sensor 10.

[0023] Please see Figures 2-4 Multiple sliding blocks 14 are fixedly connected to the outer end of the inner sliding column 8, and multiple vertical outer sliding grooves 13 are opened on the outer end of the hollow outer cylinder 7. The inner sliding column 8 and the hollow outer cylinder 7 are slidably connected through the corresponding vertical outer sliding grooves 13 and sliding blocks 14. The front end of the equipment base 1 is equipped with a material conveying rolling belt 2.

[0024] Please see Figures 1-4A support top frame 15 is fixedly connected to the upper end of the equipment base 1. Multiple elastic balls 16 are fixedly connected to the upper end of the support top frame 15. A top horizontal plate 17 is fixedly connected to the upper end of the multiple elastic balls 16. A protruding brush strip 18 is fixedly connected to the upper end of the top horizontal plate 17. The protruding brush strip 18 and multiple negative pressure suction heads 5 are in intermittent contact with each other. A transverse electric guide rail 19 is fixedly connected to the upper end of the equipment base 1. The output end of the transverse electric guide rail 19 is connected to the electric robotic arm 4. The adsorption block 3 moves and displaces above the conveying rolling belt 2.

[0025] The working principle of this utility model is as follows: The material rolling belt 2 continuously conveys the material to be stacked, realizing automatic material feeding, reducing manual intervention, and improving feeding efficiency. The electromechanical arm 4 drives the adsorption block 3 to move down and approach the material. When the negative pressure suction head 5 contacts the material, the negative pressure generates an adsorption force to firmly fix the material. At this time, the inner sliding column 8 slides upward along the hollow outer cylinder 7 under the reaction force of the material. The sliding outer block 14 cooperates with the vertical outer sliding groove 13 to ensure that the inner sliding column 8 slides smoothly without deviation. The upward movement of the inner sliding column 8 drives the protruding contact block 12 to compress the vertical spring 11 until the protruding contact block 12 contacts the contact sensor 10 on the inner top plate 9. The contact sensor 10 sends a signal to confirm that the material is adsorbed in place, which will activate the negative pressure suction head 5 at the corresponding position. The remaining positions of the negative pressure suction head 5 will then activate. The first 5 is not started to avoid unnecessary energy consumption. After adsorption is completed, the electromechanical arm 4 moves the material to the stacking position, releases the negative pressure to place the material stably, and the stacking gap is closed. The horizontal electromechanical rail 19 drives the electromechanical arm 4 to achieve precise horizontal displacement. The electromechanical arm 4 moves the adsorption block 3 to above the supporting top frame 15. The negative pressure suction head 5 contacts the protruding brush strip 18 on the top horizontal plate 17. The relative movement achieves cleaning of the negative pressure suction head 5, avoiding material residue from affecting the subsequent adsorption effect. The elastic ball 16 can buffer the impact force when the adsorption block 3 contacts the top horizontal plate 17, protect the components and extend their service life. After the material is released, the vertical spring 11 pushes the inner sliding column 8 to reset, so that the negative pressure suction head 5 returns to the initial state and is ready for the next adsorption operation.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
