Description

Technical Field

[0001] This invention relates to the field of automated gripping technology, specifically to a vacuum suction cup device for automated gripping. Background Technology

[0002] Vacuum suction cups are widely used in automated operations such as logistics handling, automated loading and unloading, and warehouse sorting. They are a common core device in automated material handling operations, undertaking the adsorption and transfer functions of various workpieces and boxes. Their structural layout and air circuit control form directly determine the quality of material handling operations and operating costs.

[0003] Existing vacuum suction cups mostly adopt a structure with a fixed overall surface or a large-sized fixed partition, and the air circuit system uses a centralized unified control mode, with each partition synchronously completing air supply and start / stop actions. During operation, the adsorption area not covered by the workpiece is continuously connected to the atmosphere, which easily causes frequent fluctuations in the internal vacuum level, requiring the vacuum supply equipment to maintain high-load operation for a long time. When the workpiece specifications change, the entire suction cup body and matching air circuit valves need to be disassembled and replaced, making the adaptation and adjustment process cumbersome and the applicable working conditions relatively limited. To address this, an automated vacuum suction cup device for gripping is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated gripping vacuum suction cup device to solve the aforementioned technical problems of frequent fluctuations in internal vacuum, the need for vacuum supply equipment to maintain high-load operation for extended periods, cumbersome adaptation and adjustment processes, and limited applicable operating conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated gripping vacuum suction cup device, comprising: The suction cup panel and the reinforced aluminum profile on the front of the suction cup panel are provided. The two sides of the reinforced aluminum profile are respectively connected to the fixed sheet metal and the first air distribution block by the first screw. The third air distribution block is connected to the outside of the fixed sheet metal by the second screw. The center of the reinforced aluminum profile is connected to the fixing component by the fourth screw. The outside of the fixing component is connected to the second air distribution block by the fifth screw. The outside of the first air distribution block, the second air distribution block and the third air distribution block are all connected to the solenoid valve by the straight connector. The outside of the solenoid valve is connected to the solenoid valve fixing plate by the third screw. The outside of the solenoid valve is threaded with the quick-connect elbow. The main air inlet port of the first air distribution block, the second air distribution block and the third air distribution block is connected to the pagoda connector. The outside of the first air distribution block, the second air distribution block and the third air distribution block are all provided with the digital vacuum gauge. The first air distribution block, the second air distribution block and the fixing component and the third air distribution block and the fixed sheet metal are respectively connected to the corresponding solenoid valve fixing plate, quick-connect elbow, solenoid valve, pagoda connector and digital vacuum gauge to form three independent control valve islands. The vacuum nozzle is threadedly connected to an independent vacuum chamber on the back of the suction cup panel. The front of the suction cup panel is connected to a photoelectric sensor for material detection via a bracket. Quick-connect connectors are evenly arranged on the front of the suction cup panel. The vacuum air path of the suction cup panel is connected to the air pipe of the quick-connect elbow, and the quick-connect elbow is connected to the quick-connect connector.

[0006] After the equipment starts up and completes initialization, all solenoid valves are closed by default, the device enters standby mode, the external detection module starts scanning, and at the same time completes the self-test calibration of each gas circuit unit to confirm that each component is in normal working condition.

[0007] After the detection module identifies the workpiece to be grasped, the system obtains the workpiece's external dimensions and placement position, matches the corresponding single-row adsorption unit, determines the opening and closing combination of the corresponding solenoid valve, and completes the configuration of the operation parameters.

[0008] The control system opens the solenoid valve in the corresponding area based on the matching result. The negative pressure is applied to the corresponding independent vacuum chamber in the suction cup panel through the corresponding air distribution block, quick-connect elbow, and quick-connect connector, so that the corresponding vacuum nozzle forms a negative pressure to adsorb the workpiece. The solenoid valve in the area not covered by the workpiece remains closed, and the corresponding vacuum chamber remains sealed.

[0009] Throughout the workpiece handling process, a digital vacuum gauge collects the negative pressure parameters of the corresponding air path in real time, while a photoelectric sensor detects the axial displacement of the vacuum nozzle. Both types of detection signals are fed back to the control system in real time. When the negative pressure value is lower than the preset safety threshold or the photoelectric sensor detects that the vacuum nozzle has not reached the preset adsorption displacement, it is determined to be an abnormal working condition. The system immediately triggers an audible and visual alarm and links the external handling equipment to suspend operation.

[0010] After the workpiece is transported to the target station, the control system controls the two-position three-way solenoid valve, which is in operation, to switch the air path, connecting the air path on the vacuum nozzle side to the atmosphere and introducing atmospheric pressure air to break the negative pressure state of the vacuum nozzle. As the negative pressure dissipates, the vacuum nozzle automatically resets and retracts. After the suction force completely dissipates, the workpiece falls smoothly into place, and the device automatically resets to standby mode, awaiting the next work instruction.

[0011] Preferably, the outer edge of the suction end face of the vacuum nozzle is integrally provided with an outward-folding sealing lip, and the outward-folding sealing lip extends around the entire circumference of the suction opening of the vacuum nozzle and tilts and folds outward.

[0012] When the vacuum nozzle is pressed against the workpiece surface to draw a vacuum, the outward-flaring sealing lip adheres tightly to the workpiece surface under atmospheric pressure. As the negative pressure increases, it gradually compacts, filling gaps on the workpiece surface and maintaining a sealed state at the adsorption end. When the pressure is released, the negative pressure dissipates, and the outward-flaring sealing lip returns to its original position along with the vacuum nozzle, detaching from the workpiece surface.

[0013] Preferably, the detection end of the material detection photoelectric sensor is horizontally aligned with the side wall reference surface of the vacuum nozzle, and the detection end of the material detection photoelectric sensor corresponds to the axial displacement path position of the vacuum nozzle.

[0014] When the vacuum nozzle adsorbs a workpiece and generates axial displacement, the photoelectric sensor detects the positional change of the sidewall reference surface to identify the displacement state of the vacuum nozzle and feeds the detection signal back to the control system to determine the adsorption and adhesion status. After depressurization and reset, the vacuum nozzle returns to its initial position, and the photoelectric sensor resets to its initial detection state.

[0015] Preferably, the quick-connect connector is connected to each of the independent vacuum chambers in the corresponding column of the suction cup panel, and adjacent independent vacuum chambers in the suction cup panel are physically isolated from each other.

[0016] Negative pressure enters the corresponding independent vacuum chamber through the quick-connect connector, acting solely on the vacuum nozzles in that chamber. Adjacent independent vacuum chambers are not connected to each other, each independently completing vacuum extraction and depressurization operations, with no interference between their gas path states.

[0017] Preferably, the solenoid valve fixing plate is connected and fixed to the outlet ports of the first, second and third air distribution blocks via a straight connector, and the surface of the solenoid valve fixing plate is in close contact with the side walls of the first, second and third air distribution blocks.

[0018] The negative pressure output from the gas distribution block is directly transmitted to the corresponding solenoid valve through the straight connector. When the solenoid valve performs the opening and closing action, the solenoid valve fixing plate maintains the stable installation position of the valve body, ensuring the airtight connection at the gas connection point.

[0019] Preferably, the surface of the fixed sheet metal is attached to the surface of the reinforcing aluminum profile, and the fixed sheet metal and the reinforcing aluminum profile are locked and fixed at multiple points along the length direction by the first screw.

[0020] When the valve island assembly is subjected to air pressure and equipment vibration, the fixed sheet metal evenly transmits the load to the reinforced aluminum profile, and the multi-point locking structure keeps the valve island fixed in place without offset or loosening.

[0021] Preferably, the pagoda connector is threaded to the main air intake port of the first air distribution block, the second air distribution block, and the third air distribution block, and the pagoda connector interface faces outward of the device and is connected to the external vacuum circuit.

[0022] The external vacuum circuit connects to the main air circuit inside the distribution block via a pagoda connector. Negative pressure enters the distribution block through the main air inlet port and is distributed to the solenoid valves of each branch. When disassembling or assembling the air circuit, simply insert and unplug the external pipeline along the interface direction.

[0023] Preferably, the digital vacuum gauge is connected to the gas path branch of the first gas distribution block, the second gas distribution block, and the third gas distribution block, and the detection end of the digital vacuum gauge is interconnected with the internal gas path of the first gas distribution block, the second gas distribution block, and the third gas distribution block.

[0024] The negative pressure inside the gas distribution block is transmitted to the detection end of the digital vacuum gauge. The digital vacuum gauge collects the negative pressure parameters of the corresponding valve island gas path in real time and transmits the detection data to the control system to monitor the gas path operation status.

[0025] Preferably, the quick-connect elbow is connected to the corresponding quick-connect connector via an external air pipe to form a single independent vacuum air passage.

[0026] When the solenoid valve is turned on, the negative pressure is conducted through the quick-connect elbow, external air pipe, and quick-connect connector to the corresponding independent vacuum chamber, forming a single, independent negative pressure conduction path. When the solenoid valve is turned off, this air passage is simultaneously shut off and closed.

[0027] Preferably, the end face of the fastener is attached to the center position of the reinforcing aluminum profile and locked in place by a fourth screw.

[0028] The load of the intermediate valve island assembly is transmitted to the central area of ​​the reinforced aluminum profile through the fasteners. The locking structure maintains the stability of the intermediate gas distribution block installation position and keeps it symmetrically arranged with the valve islands on both sides.

[0029] Compared with the prior art, the present invention provides an automated gripping vacuum suction cup device, which has the following beneficial effects: This automated gripping vacuum suction cup device relies on the corresponding connection structure between three sets of independent control valve islands and each row of independent vacuum chambers in the suction cup panel. Each row of vacuum nozzles can independently control the air path opening and closing through the corresponding solenoid valve. It can accurately match the actual size of the workpiece to open the corresponding adsorption area and close the air path of the idle area, avoid leakage in the suspended area, stabilize the internal vacuum state, and reduce the operating load of the vacuum supply equipment.

[0030] It adopts a single-row independent air path control architecture, which can adapt to different sizes of workpieces without disassembling and replacing the suction cup panel and the matching valve island and air path components. The adsorption coverage range can be adjusted by simply adjusting the opening and closing state of the corresponding solenoid valve, adapting to the gripping operation of various specifications of workpieces, and improving the device's adaptability to working conditions and the flexibility of production operations.

[0031] The digital vacuum gauge and the photoelectric sensor for material detection work together to simultaneously detect the working status of each adsorption unit. Combined with the independently partitioned gas path structure, it can locate abnormal working units, identify the risk of adsorption failure in a timely manner, trigger corresponding protective actions, and improve the stability and safety of workpiece handling operations.

[0034] This invention provides a technical solution: an automated gripping vacuum suction cup device, comprising: (see details) Figures 1-6 The suction cup panel 2 and the reinforcing aluminum profile 3 are disposed on the front of the suction cup panel 2. A fixed sheet metal 6 and a first air distribution block 14 are respectively connected to both sides of the reinforcing aluminum profile 3 by first screws. A third air distribution block 7 is connected to the outside of the fixed sheet metal 6 by second screws. A fixing member 13 is connected to the center of the reinforcing aluminum profile 3 by a fourth screw. A second air distribution block 12 is connected to the outside of the fixing member 13 by a fifth screw. Solenoid valves 10 are connected to the outside of the first air distribution block 14, the second air distribution block 12, and the third air distribution block 7 via straight-through connectors. The outside of each solenoid valve 10 is connected to a third screw. The solenoid valve is connected to a solenoid valve mounting plate 8, and quick-connect elbows 9 are threadedly connected to the outside of the solenoid valve 10. The main air inlet ports of the first air distribution block 14, the second air distribution block 12, and the third air distribution block 7 are all connected to pagoda connectors 11. Digital vacuum gauges 15 are installed on the outside of the first air distribution block 14, the second air distribution block 12, and the third air distribution block 7. The first air distribution block 14, the second air distribution block 12 and the fixing part 13, and the third air distribution block 7 and the fixing sheet metal 6 respectively form three independent control valve islands with the corresponding solenoid valve mounting plate 8, quick-connect elbows 9, solenoid valve 10, pagoda connectors 11 and digital vacuum gauges 15. Vacuum nozzle 1 is threadedly connected to an independent vacuum chamber on the back of suction cup panel 2. The front of suction cup panel 2 is connected to a material detection photoelectric sensor 5 via a bracket. Quick-connect connectors 4 are evenly arranged on the front of suction cup panel 2. The vacuum air passage of suction cup panel 2 is connected to the air pipe of quick-connect elbow 9. Quick-connect elbow 9 is connected to quick-connect connector 4.

[0035] The three sets of independent control valve islands correspond one-to-one with the single-row independent vacuum chambers in the suction cup panel 2. Together with the solenoid valve 10, they realize the independent on-off control of the single-row vacuum nozzle 1, which can accurately match the adsorption area of ​​workpieces of different sizes. The idle adsorption area is completely sealed off, effectively reducing vacuum leakage, stabilizing the vacuum degree inside the device, and reducing the operating load of the vacuum power equipment.

[0036] Based on the independent and controllable pneumatic circuit architecture, when changing to workpieces of different specifications, only the opening and closing combination of the solenoid valve 10 needs to be adjusted to complete the adaptation. There is no need to disassemble and replace the suction cup body and the matching pneumatic circuit valve body components, which shortens the changeover adjustment cycle and improves the flexible operation capability and overall operation efficiency of the device.

[0037] The digital vacuum gauge 15 and the photoelectric sensor 5 for material detection form a dual detection and protection system, which can simultaneously monitor the negative pressure status of the gas path and the adsorption and adhesion status, promptly identify abnormal working conditions and trigger protective interlock actions, avoid the risk of workpiece falling off and breaking, and improve the stability and safety of continuous operation of the device.

[0038] The aluminum profile 3 is reinforced to support the valve island assembly in conjunction with the fixed sheet metal 6 and the fastener 13, thereby improving the overall structural strength of the device and the stability of the valve island installation. This ensures the structural reliability of the device under high-speed continuous operation conditions and facilitates the disassembly, maintenance and replacement of each component.

[0039] Please see Figure 2 and Figure 3 The outer edge of the suction end face of the vacuum nozzle 1 is integrally provided with an outward-folding sealing lip, and the outward-folding sealing lip extends around the entire circumference of the nozzle opening of the vacuum nozzle 1 and tilts and folds outward.

[0040] The outward-flaring sealing lip is integrated with the vacuum nozzle 1, which enhances the sealing performance of the adsorption end face, reduces micro-leakage of a single vacuum nozzle 1, stabilizes the negative pressure state inside the vacuum chamber, and improves the reliability of adsorption operations. The integrated structure requires no additional assembly, is simple in design, and is convenient for assembly and maintenance.

[0041] The detection end of the material detection photoelectric sensor 5 is horizontally aligned with the side wall reference surface of the vacuum nozzle 1, and the detection end of the material detection photoelectric sensor 5 corresponds to the axial displacement path position of the vacuum nozzle 1.

[0042] By detecting the physical displacement of the vacuum nozzle 1, the adsorption state can be determined, avoiding the interference of workpiece surface properties on the detection results, improving the accuracy and anti-interference ability of the detection results, and the detection feedback directly corresponds to the physical state of the adsorption action, which is more in line with the actual adsorption conditions.

[0043] The quick-connect connector 4 is connected to the corresponding independent vacuum chambers in the suction cup panel 2, and adjacent independent vacuum chambers in the suction cup panel 2 are physically isolated from each other.

[0044] Each independent vacuum chamber is physically isolated and supplied with gas through quick-connect fittings 4, which ensures the independence of gas path control for each row, avoids crosstalk between gas paths of adjacent chambers, ensures the accuracy of opening and closing control of each row, and provides a stable structural basis for on-demand adsorption.

[0045] Please see Figure 4 , Figure 5 and Figure 6 The solenoid valve fixing plate 8 is fixed to the outlet ports of the first air distribution block 14, the second air distribution block 12 and the third air distribution block 7 through a straight connector, and the surface of the solenoid valve fixing plate 8 is in close contact with the side walls of the first air distribution block 14, the second air distribution block 12 and the third air distribution block 7.

[0046] The solenoid valve mounting plate 8 fits snugly against the side wall of the gas distribution block, which can improve the structural stability of the solenoid valve 10 installation, while shortening the gas path connection, reducing the risk of leakage at the gas connection point, and ensuring the airtightness and reliability of the gas transmission.

[0047] The surface of the fixed sheet metal 6 is attached to the surface of the reinforcing aluminum profile 3, and the fixed sheet metal 6 and the reinforcing aluminum profile 3 are locked and fixed at multiple points along the length direction by the first screw.

[0048] The multi-point locking fitting installation method can enhance the connection strength between the fixed sheet metal 6 and the reinforced aluminum profile 3, improve the installation stability of the valve island assembly, disperse the vibration load generated by equipment operation, and avoid the problem of loose connection during long-term operation.

[0049] The pagoda connector 11 is threaded to the main air intake port of the first air distribution block 14, the second air distribution block 12 and the third air distribution block 7, and the interface of the pagoda connector 11 faces the outside of the device and is connected to the external vacuum circuit.

[0050] The pagoda connector 11 is arranged facing outwards from the device, which facilitates the connection, disassembly, and maintenance of the external vacuum circuit. The threaded connection ensures the sealing performance of the air inlet port, reduces the probability of leakage at the main air inlet, and improves the convenience and sealing of the air circuit connection.

[0051] The digital vacuum gauge 15 is connected to the gas path branch of the first gas distribution block 14, the second gas distribution block 12 and the third gas distribution block 7, and the detection end of the digital vacuum gauge 15 is interconnected with the internal gas path of the first gas distribution block 14, the second gas distribution block 12 and the third gas distribution block 7.

[0052] The digital vacuum gauge 15 is directly connected to the internal gas path of the gas distribution block, which can accurately collect the real negative pressure parameters of the corresponding valve island. The detection data is closer to the actual working gas path state, improving the accuracy of negative pressure monitoring and providing a reliable basis for judging abnormal working conditions.

[0053] The quick-connect elbow 9 connects to the corresponding quick-connect connector 4 via an external air pipe, forming a single independent vacuum air passage.

[0054] The quick-connect structure forms a single-row independent gas path, which is convenient for gas path connection and has good sealing performance. It can ensure the independence and smoothness of the gas path conduction, and at the same time facilitates the disassembly, maintenance and troubleshooting of a single gas path.

[0055] The end face of the fastener 13 is attached to the center of the reinforcing aluminum profile 3 and locked in place by the fourth screw.

[0056] The fastener 13 is centrally positioned and locked in place, which ensures the installation stability of the intermediate valve island assembly, evenly strengthens the load-bearing capacity of the aluminum profile 3, optimizes the load distribution of the overall structure, and improves the balance and stability of the overall structure of the device.

[0057] This solution: This device is equipped with a main control unit, which uses a programmable logic controller (PLC) as its core hardware carrier. It integrates a signal acquisition module, a logic operation module, a valve island control module, an anomaly interlock module, and a communication interaction module. The signal acquisition module receives feedback signals from various detection elements; the logic operation module analyzes workpiece parameters, matches adsorption unit combinations, and determines operating conditions; the valve island control module outputs control commands for airflow on / off and switching; the anomaly interlock module triggers alarms and equipment shutdown interlocks; and the communication interaction module interfaces with external host systems to transmit operational status and receive scheduling commands.

[0058] After the device is powered on, each module of the main control unit completes its initialization sequentially. All solenoid valves 10 are in the closed state by default, and the device enters standby mode. The external vacuum source remains connected to the pagoda connector 11 and is in standby mode. The externally matched visual recognition module and laser positioning module start their scanning functions. The signal acquisition module synchronously acquires the initial status parameters of each gas path, completes the self-test calibration of each individual gas path unit, and confirms that all components are in normal operating condition.

[0059] After the visual recognition module and laser positioning module detect the workpiece to be grasped, they transmit the workpiece's shape and position information to the main control unit. The logic operation module parses the received workpiece parameters, matches them with the corresponding covered single-row adsorption units, determines the opening and closing combination scheme of the corresponding solenoid valve 10, and completes the automatic configuration of the operation parameters.

[0060] The valve island control module outputs control commands based on the configuration results, opening the solenoid valve 10 in the corresponding area. Negative pressure is transmitted through the corresponding air distribution block, quick-connect elbow 9, external air pipe, and quick-connect connector 4 to the corresponding independent vacuum chamber within the suction cup panel 2. These independent vacuum chambers are mutually sealed, creating negative pressure on the corresponding vacuum nozzle 1 and causing it to adhere to the workpiece surface. The outward-flaring sealing lip is pressed firmly against the workpiece surface by the negative pressure. The solenoid valve 10 in areas not covered by the workpiece remains closed, and the corresponding independent vacuum chamber remains sealed.

[0061] Throughout the workpiece handling process, the digital vacuum gauge 15 collects the negative pressure parameters of the corresponding air path in real time, while the material detection photoelectric sensor 5 synchronously detects the axial displacement of the vacuum nozzle 1. Both types of detection signals are transmitted to the signal acquisition module in real time and fed back to the logic operation module. The logic operation module determines the operating conditions in real time. When an abnormal condition is detected, the abnormal interlock module immediately triggers the audible and visual alarm unit to output an alarm signal, and simultaneously links external equipment to suspend operation.

[0062] After the workpiece is transported to the target station, the valve island control module outputs a switching command, controlling the solenoid valve 10, which is in operation, to switch the air path and introduce normal pressure air to break the negative pressure state of the vacuum nozzle 1. The outward-facing sealing lip resets synchronously as the negative pressure dissipates. After the adsorption force completely dissipates, the workpiece is smoothly placed at the target station, and the device automatically resets to the standby state, waiting for the next work command to continuously perform gripping operations.
