Description

Technical Field

[0001] This utility model belongs to the technical field of adsorption devices, and in particular relates to a multi-head adjustable vacuum suction cup device. Background Technology

[0002] In industrial material handling, assembly, and processing, vacuum adsorption is a common and efficient non-destructive gripping method. However, traditional multi-head vacuum suction cup devices have the following limitations in practical applications: 1. Poor adaptability and cumbersome adjustment: The position of the suction cup in most devices is fixed or can only be adjusted in a limited number of preset holes. When the size, shape or center of gravity of the workpiece changes, it is necessary to redesign or laboriously disassemble and move the suction cup base. The adjustment efficiency is low and it cannot quickly respond to changes in production.

[0003] 2. Insufficient adsorption stability: For workpieces with slightly undulating, uneven, or soft surfaces, rigidly mounted suction cups may experience poor contact, leading to localized air leakage, affecting the overall adsorption force, and even causing the workpiece to fall off or be damaged. There is a lack of effective buffering and adaptive compensation mechanisms.

[0004] 3. Complex structure and inconvenient maintenance: Vacuum tubing is often messy and prone to interference with moving parts. Adjusting the suction cup position requires simultaneous rearranging of the long, cumbersome tubing, making the operation tedious. The frame structure is bulky and difficult to modularly expand or shrink according to the task.

[0005] 4. Poor control of neutrality and balance: When hoisting large plates, if the suction cup layout cannot flexibly adapt to the center of gravity of the workpiece, it may lead to unbalanced hoisting and create safety hazards.

[0006] Therefore, there is an urgent need for a multi-head vacuum suction cup device with flexible and continuous adjustment of suction cup spacing, adaptive buffering capability, orderly pipeline management, and a stable and reliable structure. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-head adjustable vacuum suction cup device. Through the design of the main beam and the sub-beam that can slide along the main beam, the position of the suction cup in a two-dimensional plane is continuously adjustable. One set of devices can be adapted to workpieces of various sizes and shapes, significantly reducing the number of special tooling and changeover time, and improving equipment utilization and production flexibility.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a multi-head adjustable vacuum suction cup device, including an adjustable frame, a vacuum suction box and several suction cup bodies; The upper and lower parts of the vacuum suction box are respectively equipped with a vacuum generating device and a common chamber; The adjustable frame includes main beams, all of which are rectangular steel tubes, and several secondary beams. The vacuum suction box is installed at the midpoint of the top of the main beam. The bottom of the vacuum suction box, which extends beyond the main beam, has several interfaces for connecting to the common chamber. A crossbeam is fixed at the bottom of the center of the main beam and is perpendicular to the main beam. The top of the sub-beam is fixed with a sliding hoop, and several of the crossbeams are linearly arranged at the bottom of the main beam and parallel to the crossbeams. The sub-beam slides with the main beam through the sliding hoop, and the top of the sliding hoop is provided with a fastening mechanism connected to the main beam. Both ends of the sub-beam and both ends of the crossbeam are provided with strip-shaped through openings along the length direction. Several suction cups are arranged in pairs at the bottom of both ends of the crossbeam and several sub-beams. The suction cups are installed at the strip-shaped through openings of the sub-beams through buffer connectors. The air supply port of the suction cup is connected to the interface on the common chamber through a hose. The hoses at both ends of the same sub-beam are tied at the top and bottom of the main beam with cable ties, and the hoses between the two cable ties form a fastening point on the main beam.

[0009] Furthermore, the buffer connector includes a telescopic tube, both ends of which are provided with end plates. A spring is fixed between the two end plates. The end plate at the bottom of the telescopic tube is fixed to the top of the suction cup body. The end plate at the top of the telescopic tube is attached to the sub-beam and is provided with a locking screw with a through strip-shaped opening. The top of the locking screw is provided with a nut that presses against the top of the sub-beam.

[0010] Furthermore, the fastening mechanism includes a threaded sleeve, which is fixed to the top of the sliding hoop. A fastening screw is internally threaded onto the threaded sleeve, and a handle is provided at the top of the fastening screw.

[0011] Furthermore, several mounting holes are linearly provided at both ends of the top of the main beam, and the sliding hoop is fixed to the main beam through a fastening mechanism and the mounting holes.

[0012] Furthermore, a hanger is fixed at the top axis of the vacuum suction box.

[0013] Furthermore, both ends of the main beam and the secondary beam are provided with end caps.

[0014] Furthermore, the width of the vacuum suction box exceeds the width of the main beam, and reinforcing angle irons are provided between the bottom areas of the vacuum suction box on both sides that extend beyond the main beam and the main beam.

[0015] This utility model has the following beneficial effects: 1. This utility model achieves stepless and continuous adjustment of the position of the suction cup in a two-dimensional plane through the design of the main beam and the secondary beam that can slide along the main beam. One set of devices can be adapted to workpieces of various sizes and shapes, significantly reducing the number of special tooling and replacement time, and improving equipment utilization and production flexibility.

[0016] 2. This utility model, through the design of a buffer connector with telescopic capability, enables the suction cup to have a vertical buffer stroke when contacting the workpiece, which can automatically compensate for slight unevenness of the workpiece surface, ensure that each suction cup can fit tightly and balance the adsorption force, and at the same time absorb slight vibrations during transportation, effectively preventing scratches or damage to the workpiece surface, especially suitable for polishing sheets, glass or precision parts.

[0017] 3. This utility model, through the design of the flexible hose system, uses cable ties to secure the flexible hoses at both ends of the same sub-beam at specific locations on the main beam, forming a fastening point. This ensures the vacuum pipeline is orderly, preventing tangling, pulling, and wear of the hoses during adjustment and movement, and also resulting in a neat overall appearance, facilitating inspection and maintenance. When adjusting the suction cup position, the hoses move in an orderly manner without causing confusion.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
