Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a clamp for automatically handling cardboard boxes. Background Technology

[0002] With the rise of e-commerce and the prosperity of global trade, the logistics industry has experienced explosive growth. The volume of goods handled in logistics centers, warehouses and other places has increased significantly. The traditional method of manually handling cardboard boxes is inefficient, labor-intensive and prone to errors and safety accidents, making it difficult to meet the requirements of fast and efficient operation in modern logistics. Automated cardboard box handling fixtures are widely used in the logistics field, enabling rapid loading, unloading, palletizing and handling of cardboard boxes, improving logistics operation efficiency and reducing costs. For example, in large e-commerce warehouses, a large number of goods need to be quickly sorted and packed into cardboard boxes and then transported to the shipping area. Automated cardboard box handling fixtures, in conjunction with automated sorting systems and warehouse robots, can greatly improve the operational efficiency of the warehouse.

[0003] The applicant discovered through a search that a Chinese patent, "A Clamp for Carton Palletizing," with publication number "CN220011377U," is disclosed. This patent mainly comprises a mounting base, a clamping unit, a power unit, and a sponge suction cup unit. The mounting base is used to install on a palletizing robot. The clamping unit includes a first clamping plate and a second clamping plate arranged opposite to each other. The first clamping plate is fixedly connected to the mounting base, and the second clamping plate is movably disposed on the mounting base. The power unit is disposed on the mounting base and is used to drive the second clamping plate to move toward or away from the first clamping plate so that the first clamping plate and the second clamping plate can clamp goods. The sponge suction cup unit is disposed on the mounting base and located between the first clamping plate and the second clamping plate. The sponge suction cup unit is used to absorb goods. During the process of clamping cartons, the cardboard palletizing clamp of this utility model can ensure that the cartons will not fall while effectively reducing the clamping force of the two clamping plates on the cartons, thereby effectively preventing the cartons from deforming. In addition, it can also handle cartons with large weight and volume, and has strong applicability.

[0004] However, the following shortcomings still exist:

[0005] In automated material handling scenarios, suction cups hold cartons for extended periods, making their surfaces highly susceptible to damage from the cartons. During frequent handling, dust, debris, and other impurities continuously fall off the cartons and adhere to the suction cups. Over time, these impurities not only alter the original smoothness of the suction cup surface but also fill the tiny gaps between the suction cup and the cartons, severely reducing the sealing performance. This results in insufficient suction power from the suction cups during operation, causing cartons to detach during handling and significantly impacting the stability and continuity of the handling process. To address this, we propose an automated carton handling clamp. Utility Model Content

[0006] The purpose of this invention is to provide a clamp for automatically handling cardboard boxes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic cardboard box handling clamp, including a fixed base, support plates fixed on both sides below the fixed base, a clamping plate fixed below the support plates, the clamping plate connected to a suction cup via a support rod on one side, a plurality of suction holes opened on the side of the suction cup, a vacuum generator provided on the other side of the clamping plate, the vacuum generator being connected to the suction cup via an upper air supply pipe, a cleaning assembly mounted above the suction cup, the cleaning assembly including an air compressor, an air tank, an air supply pipe, an air duct, and a nozzle, the air compressor being located above the vacuum generator, the air tank being located above the air compressor, the air supply pipe being connected to the nozzle via an air duct, a plurality of nozzles being provided, the nozzles being located above the suction cup.

[0008] As a further embodiment of this utility model: an electric telescopic rod is provided on both sides below the clamping plate, and the clamping plate is connected to the fixing plate through the electric telescopic rod below.

[0009] As a further embodiment of this utility model: a limiting plate is provided on both sides of the fixing plate, a guide rail is provided on the inner side of the limiting plate, and guide rail grooves are opened on both sides of the inner side of the limiting plate, the guide rail grooves and the guide rail are positioned correspondingly.

[0010] As a further embodiment of this utility model: a second locking plate is internally engaged with the second guide rail, the second locking plate and the first limiting plate are integrally formed, the other end of the first limiting plate is provided with the second limiting plate, the inside of the second limiting plate is provided with a slot corresponding to the position of the second locking plate, a support plate is sleeved on the outside of the second guide rail, the support plate and the second locking plate are connected, and an electric telescopic rod is provided on the side of the support plate.

[0011] As a further embodiment of this utility model: guide rails are provided on both sides below the fixed base, a locking plate is engaged inside the guide rails, and a bidirectional screw is provided below the guide rails.

[0012] As a further embodiment of this utility model: a slider is sleeved on the outside of the bidirectional screw, the slider is connected to a guide rail via a clamping plate above, and the bidirectional screw is connected to the drive end of the motor.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model uses an air compressor to compress air and store it in an air tank to ensure a sufficient air supply for subsequent cleaning. The air supply pipe 2 introduces the compressed air from the air tank into the air pipeline. Multiple jet nozzles distributed above the suction cup spray the compressed air evenly onto the surface of the suction cup to achieve all-round cleaning of the suction cup, thereby cleaning up dust and impurities, maintaining the suction effect of the suction cup, avoiding the influence of dirt on the suction force, and ensuring stable and reliable handling.

[0015] 2. This utility model uses the extension and retraction of the electric telescopic rod 2 to drive the connected pallet to slide outside the guide rail 2, so that the clamping plate 2 moves synchronously. Because the clamping plate 2 is clamped inside the guide rail 2, it is connected to the limiting plate 1. When the clamping plate 2 moves, the limiting plate 1 also moves synchronously. The limiting plate 1 slides outside the guide rail groove, and the clamping plate 2 slides in the corresponding groove. When the limiting plate 1 approaches and reaches the limiting plate 2, the limiting plate 2 prevents the limiting plate 1 from falling out. Therefore, the pallet is driven by the electric telescopic rod 2 to lift the bottom of the carton, providing reliable support for handling and improving the safety and efficiency of handling.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 5 This utility model discloses an automatic cardboard box handling clamp, including a fixed base 1, with support plates 2 fixed on both sides below the fixed base 1. (The rest of the text appears to be a continuation of the previous sentence.) Figure 1 , Figure 2 as well as Figure 4 As shown, a clamping plate 3 is fixed below the support plate 2. The clamping plate 3 is connected to a suction cup 5 via a support rod 4 on one side. Several suction holes 51 are opened on the side of the suction cup 5. A vacuum generator 52 is set on the other side of the clamping plate 3. The vacuum generator 52 is connected to the suction cup 5 via an upper air supply pipe 53. A cleaning assembly 6 is mounted above the suction cup 5. The cleaning assembly 6 includes an air compressor 61, an air tank 62, an air supply pipe 63, an air duct 64, and a jet nozzle 65. The air compressor 61 is located below the vacuum generator 5. Above the suction cup 5, an air tank 62 is mounted on the air compressor 61. An air supply pipe 63 connects to the air nozzles 65 via an air duct 64. Several nozzles 65 are provided and are positioned above the suction cup 5. A support rod 4 connects the clamping plate 3 to the suction cup 5. The clamping plate 3 cooperates with the support plate 2 to ensure the suction cup 5 maintains the correct position and orientation during handling, facilitating stable adsorption and handling of the cardboard box. A vacuum generator 52 is connected to the suction cup 5 via an air supply pipe 53. When handling is initiated... Vacuum generator 52 operates rapidly, and suction port 51, influenced by vacuum generator 52, strongly sucks the air between suction cup 5 and the surface of cardboard box. The resulting suction force causes suction cup 5 to adhere to the cardboard box, thus gripping it. After suction cup 5 undergoes multiple rounds of handling and suction cycles, air compressor 61 compresses air and delivers it to air tank 62. Air tank 62 stores the compressed air from air compressor 61, ensuring a sufficient supply of compressed air to maintain the stability and continuity of the cleaning operation and prevent insufficient air supply from affecting the cleaning effect. Subsequently, air supply pipe 63 introduces the compressed air from air tank 62 into air pipe 64, while multiple air nozzles 65 are distributed above suction cup 5, evenly spraying compressed air onto the surface of suction cup 5 to achieve all-round cleaning of suction cup 5. Therefore, dust and impurities adhering to the surface of suction cup 5 can be thoroughly cleaned through air nozzles 65, thereby ensuring the suction effect of suction cup 5, preventing the suction force from being affected by dirt on the surface of suction cup 5, and ensuring the stability and reliability of the handling process.

[0026] In Embodiment 1, electric telescopic rods 7 are provided on both sides below the clamping plate 3, and the clamping plate 3 is connected to the fixing plate 8 through the electric telescopic rods 7 below.

[0027] Specifically, by extending and retracting the electric telescopic rod 7, the height of the fixing plate 8 and the pallet 85 can be adjusted so that the pallet 85 can support the bottom of the carton according to the height of different cartons, so that the bottom of the carton can be fixed above the pallet 85, preventing the risk of the carton shaking, tilting or even falling due to unstable bottom support, and improving the fixing effect of the carton.

[0028] In embodiment 2, a locking plate 2 83 is snapped into the inside of the guide rail 2 82. The locking plate 2 83 and the limiting plate 1 81 are integrated. A limiting plate 2 84 is provided at the other end of the limiting plate 1 81. The limiting plate 2 84 has a slot inside that corresponds to the position of the locking plate 2 83. A support plate 85 is sleeved on the outside of the guide rail 2 82. The support plate 85 is connected to the locking plate 2 83. An electric telescopic rod 2 86 is provided on the side of the support plate 85.

[0029] Specifically, during carton handling, when it is necessary to stably lift the bottom of the carton, the extension and retraction of the electric telescopic rod 86 causes the connected pallet 85 to slide outside the guide rail 82. During this process, the pallet 85 drives the tightly connected clamping plate 83 to move synchronously. Since the clamping plate 83 is engaged within the guide rail 82, it slides along the path defined by the guide rail 82. Due to the integrated structure of the clamping plate 83 and the limiting plate 81, when the clamping plate 83 is subjected to force and moves, the limiting plate 81 moves synchronously, passing through the guide groove inside the limiting plate 81. The pallet 85 can slide outside the guide rail 2 82, while the pallet 2 83 slides in the corresponding slot. During the movement, it continues to advance until the limiting plate 1 81 approaches and reaches the limiting plate 2 84. The limiting plate 2 84 limits the limiting plate 1 81, effectively preventing the limiting plate 1 81 from falling off the predetermined running track and preventing the handling risk caused by the loss of control of component displacement. In this way, the pallet 85, driven by the electric telescopic rod 2 86, lifts the bottom of the carton, providing solid and reliable support for the carton during the handling process, and greatly improving the safety and efficiency of the handling operation.

[0030] Working principle:

[0031] First, driven by the motor 105, the slider 104 slides outside the bidirectional screw 103, thereby adjusting the position between the suction cups 5 below, so that they move closer or further away according to the size of the carton. When the slider 104 slides, it pulls the card plate 102 to slide within the guide rail 101, improving the stability during the movement.

[0032] The support rod 4 connects the clamping plate 3 and the suction cup 5. The clamping plate 3 and the support plate 2 cooperate to ensure that the suction cup 5 is accurately positioned during handling and to ensure stable handling of the carton. During handling, the vacuum generator 52 draws air from the suction hole 51 through the air supply pipe 1 53 to the surface of the suction cup 5 and the carton, generating suction force to grip the carton. After the suction cup 5 has been handled multiple times, the air compressor 61 compresses air and stores it in the air tank 62. Then, the air supply pipe 2 63 introduces the air in the air tank 62 into the air pipe 64, and the air is evenly sprayed onto the surface of the suction cup 5 through the air nozzle 65 to clean dust and impurities, maintain suction force, and ensure reliable handling.

[0033] When supporting the bottom of the carton, the electric telescopic rod 7 extends and retracts, adjusting the height of the fixing plate 8 and the pallet 85 so that the pallet 85 supports the bottom of the carton according to its height. Then, the electric telescopic rod 86 extends and retracts, causing the pallet 85 to slide along the guide rail 82. The pallet 85 causes the clamping plate 83 to move synchronously. The clamping plate 83 slides along the guide rail 82 because it is clamped inside the guide rail 82. Because it is connected to the limiting plate 81, the two move synchronously, sliding outside the guide rail 82 and inside the slot respectively. When the limiting plate 81 approaches the limiting plate 84, the limiting plate 84 limits it to prevent it from falling out. The pallet 85 supports the bottom of the carton under the drive of the electric telescopic rod 86, ensuring safe and efficient handling. At this point, the entire workflow is completed.
