[0033] Figure 1 This is a structural schematic diagram of an electromagnetic suction cup control device provided according to an embodiment of the present utility model. This embodiment is applicable to situations where an electromagnetic suction cup is used to transport items. The electromagnetic suction cup control device can be implemented in the form of hardware. The electromagnetic suction cup control device can be configured in large-scale equipment such as industrial automation equipment, lifting systems, logistics handling equipment, and mechanical processing equipment.

[0034] like Figure 1 As shown, the device includes: a main controller 110, an energy storage module 120, a first switch 130, a second switch 140, a first voltage detection circuit 150 and a first current detection circuit 160; the first voltage detection circuit 150 and the first current detection circuit 160 are both connected between the electromagnetic suction cup 170 and the main controller 110, and are used to detect voltage and current respectively and feed back to the main controller 110; the second switch 140 is connected between the electromagnetic suction cup controller 180 and the electromagnetic suction cup 170, and the control end of the second switch 140 is connected to the main controller 110, and the main controller 110 is used to control the conduction or disconnection of the second switch 140; the first switch 130 is connected between the energy storage module 120 and the electromagnetic suction cup 170, and the main controller 110 is connected to the control end of the first switch 130; the main controller 110 is used to control the conduction or disconnection of the first switch 130.

[0035] Specifically, the main controller 110 is the core control unit of the electromagnetic chuck control device, responsible for the overall logic control and data processing of the electromagnetic chuck control device.

[0036] Energy storage module 120 provides backup power for electromagnetic chuck 170, maintaining its operational state in the event of a main power failure. Exemplarily, energy storage module 120 may include a battery pack and a battery pack control module. The battery pack control module monitors the battery capacity and automatically adjusts the battery pack's charging mode based on the battery capacity. Exemplarily, the battery pack's charging mode may be a trickle float charge, which maintains a full charge to ensure that the battery pack can be promptly activated in the event of an external fault.

[0037] The first switch 130 refers to a switch that controls the current flow state between the energy storage module 120 and the electromagnetic suction cup 170. When the first switch 130 is closed, the energy storage module 120 can supply power to the electromagnetic suction cup 170. When the first end switch 130 is open, the energy storage module 120 cannot supply power to the electromagnetic suction cup 170.

[0038] The second switch 140 refers to a switch that controls the current flow state between the electromagnetic chuck controller 180 and the electromagnetic chuck 170. When the second switch 140 is closed, the electromagnetic chuck controller 180 can control the electromagnetic chuck 170. When the second switch 140 is open, the electromagnetic chuck controller 180 cannot control the electromagnetic chuck 170.

[0039] The first voltage detection circuit 150 is a detection device used to monitor the voltage of the electromagnetic chuck 170, ensuring that the voltage is within a safe range to prevent damage to the electromagnetic chuck 170 due to overvoltage or undervoltage, which could lead to safety accidents. For example, the first voltage detection circuit 150 can be a voltage sensor. The voltage data detected by the first voltage detection circuit 150 is fed back to the main controller 110 in real time. If the voltage exceeds the set safety range, the main controller 110 can issue an alarm or automatically cut off the power supply.

[0040] The first current detection circuit 160 refers to a detection device for monitoring the current of the electromagnetic chuck 170, ensuring that its current is within a safe range and preventing the electromagnetic chuck 170 from malfunctioning or other accidents caused by overcurrent. For example, the first current detection circuit 160 can be a Hall current sensor. The current data measured by the first current detection circuit 160 is fed back to the main controller 110 to monitor current changes in real time. If the current exceeds a safety threshold, the main controller 110 can take measures, such as cutting off the power supply or adjusting the working state of the electromagnetic chuck.

[0041] An electromagnetic chuck 170 is a device that uses electromagnetic force to attract and transport metal objects. It is commonly used in industrial environments such as manufacturing, warehousing, and logistics, efficiently lifting and moving heavy metal materials. The core principle of the electromagnetic chuck 170 is electromagnetic induction. When current passes through its electromagnetic coil, it generates a magnetic field around the coil, which in turn attracts metal objects. The current is turned on and off to control the electromagnetic chuck 170's attraction and release processes, ensuring operational flexibility.

[0042] The electromagnetic chuck controller 180 is a device specifically designed to control the electromagnetic chuck 170. It manages the start / stop, suction, and release operations of the electromagnetic chuck 170, ensuring that the electromagnetic chuck 170 can safely and efficiently suction and transport objects during operation, while also allowing for quick release when necessary. The electromagnetic chuck controller 180 controls the operating state of the electromagnetic chuck 170 by issuing control signals.

[0043] In this embodiment of the present invention, the main controller 110 can issue control signals to control the operating states of the first voltage detection circuit 150, the first current detection circuit 160, the first switch 130, and the second switch 140. The first voltage detection circuit 150 and the first current detection circuit 160 can monitor the voltage and current of the electromagnetic chuck 170 in real time and promptly report any abnormalities to the main controller 110. The first switch 130 can control the energy storage module 120 to supply power to the electromagnetic chuck 170, and the second switch 140 can control the flow of current between the electromagnetic chuck controller 180 and the electromagnetic chuck 170.

[0044] For example, if the first voltage detection circuit 150 or the first current detection circuit 160 detects that the voltage or current of the electromagnetic chuck 170 is outside a set safety threshold, indicating a fault in the external power supply for the electromagnetic chuck 170, the first voltage detection circuit 150 or the first current detection circuit 160 will immediately send an abnormality signal to the main controller 110. Upon receiving the abnormality signal, the main controller 110 enters magnetic field protection control and issues a command to turn on the first switch 130, causing the energy storage module 120 to supply power to the electromagnetic chuck 170. This prevents the electromagnetic chuck 170 from losing its magnetism and causing objects to fall off, potentially leading to a safety incident.

[0045] This embodiment of the utility model monitors the operating status of the electromagnetic chuck 170 using voltage data detected by the first voltage detection circuit 150 and current data detected by the first current detection circuit 160. When an anomaly is detected, the electromagnetic chuck 170 is powered via the energy storage module 120. This utility model ensures that if the external power supply responsible for powering the electromagnetic chuck 170 fails, the electromagnetic chuck 170 can be promptly powered via the energy storage module 120, thereby preventing items from falling off the electromagnetic chuck 170 and effectively improving the safety and reliability of the electromagnetic chuck 170 during operation.

[0046] Figure 2 This is a schematic diagram of the structure of another electromagnetic chuck control device provided according to an embodiment of the present utility model. Based on the above embodiments, optional, such as Figure 2 As shown, the device further includes: a thyristor group 210, a thyristor drive circuit 211, and a voltage stabilization and filtering circuit 220. The input end of the thyristor drive circuit 211 is connected to the signal output end of the main controller 110, the output end of the thyristor drive circuit 211 is connected to the signal input end of the thyristor group 210, the power input end of the thyristor group 210 is connected to the power distribution line 230, the busbar output end of the thyristor group 210 is connected to the voltage stabilization and filtering circuit 220, and the voltage stabilization and filtering circuit 220 is connected to the energy storage module 120; the main controller 110 is used to control the operation of the thyristor group 210 through the thyristor drive circuit 211, and the thyristor group 210 is used to charge the energy storage module 120.

[0047] Specifically, the thyristor group 210 refers to a power electronic component consisting of at least two thyristors, used to control and regulate current. Capable of operating under high voltage and high current conditions, the thyristor group 210 operates by rectifying, regulating, and switching AC or DC current, primarily for power control and conversion. In this embodiment of the present invention, the thyristor group 210 is capable of rectifying AC power in the distribution line 230 into DC power to charge the energy storage module 120.

[0048] The thyristor drive circuit 211 is a circuit used to activate the thyristor group 210. Under the control of the main controller 110, the thyristor drive circuit 211 can control the conduction angle of the thyristors in the thyristor group 210 to control the current and power in the circuit. In this embodiment of the utility model, by controlling the conduction angle of the thyristor group 210 by the thyristor drive circuit 211, the energy storage module 120 can be stably supplied with power from the AC supply voltage of the distribution line 230, eliminating the need for a transformer to reduce the voltage, thereby improving resource utilization efficiency and reducing space usage.

[0049] Optionally, based on the above embodiments, the thyristor driving circuit 211 includes a phase-shift trigger circuit.

[0050] Specifically, a phase-shift trigger circuit is a circuit used to control the conduction angle of a thyristor (SCR). By adjusting the phase of the input signal, the thyristor's conduction time is precisely controlled, thereby regulating the load power. Phase-shift trigger circuits are typically based on an AC signal and control the thyristor's switching state by changing the phase position of the trigger signal.

[0051] In the embodiment of the present utility model, the phase-shift trigger circuit can reduce the risk of current mutation and overload through smooth control, so that the electromagnetic suction cup control device can flexibly adjust the trigger signal according to different application requirements, adapt to various working scenarios, and meet the needs of different users.

[0052] The voltage stabilization and filtering circuit 220 is a circuit design that provides a stable voltage output and filters out noise and fluctuations in the power supply. This circuit ensures the stability of the voltage received by the energy storage module 120, preventing voltage fluctuations from affecting battery charging and device operation. For example, the voltage stabilization and filtering circuit 220 may include components such as a voltage stabilizer, capacitors, inductors, and diodes.

[0053] The distribution line 230 refers to the electrical line system that distributes electrical energy from a power source (such as a substation, generator, or distribution cabinet) to various electrical devices and loads. It is responsible for transporting electrical energy in the power system and ensuring the efficient transmission of electrical energy.

[0054] In this embodiment of the present invention, the thyristor drive circuit 211, under the control of the main controller 110, drives the thyristor group 210 to operate, converting the AC power in the distribution line 230 into DC power. The voltage stabilization and filtering circuit 220 then outputs a stable DC voltage to power the energy storage module 120. The thyristor group 210 and thyristor drive circuit 211 can be replaced based on different usage scenarios and operating requirements. By replacing only a few components while keeping other components unchanged, other commercially available electromagnetic chucks 170 can be controlled, demonstrating high compatibility.

[0055] Continue to see Figure 2 Optionally, based on the above embodiments, the electromagnetic suction cup control device also includes: a second current detection circuit 240 and a second voltage detection circuit 241; the second current detection circuit 240 is connected between the main controller 110 and the voltage stabilization and filtering circuit 220; the second voltage detection circuit 241 is connected between the energy storage module 120 and the main controller 110.

[0056] Specifically, the second current detection circuit 240 is a circuit for real-time monitoring of the current flow in the voltage stabilization and filtering circuit 220, ensuring that the current in the voltage stabilization and filtering circuit 220 is within a safe range and preventing overcurrent from damaging the energy storage module 120 or other electronic components. For example, when the second current detection circuit 240 detects that the current in the voltage stabilization and filtering circuit 220 exceeds the safety limit, it immediately sends an alarm signal to the main controller 110, indicating that the system may be at risk of overcurrent.

[0057] The second voltage detection circuit 241 is a circuit used to monitor the output voltage of the energy storage module 120 in real time, ensuring that it is within a set safety threshold to prevent the voltage from being too high or too low. For example, when the second voltage detection circuit 241 detects that the voltage exceeds the safety range, it will send an alarm signal to the main controller 110, indicating that the system has a voltage anomaly.

[0058] In an embodiment of the present utility model, the second current detection circuit 240 and the second voltage detection circuit 241 are important safety monitoring components in the electromagnetic suction cup control device. By monitoring the current and voltage in real time, they ensure the safe operation of the voltage stabilization and filtering circuit 220 and the energy storage module 120, and prevent equipment damage or safety accidents caused by abnormal current or voltage.

[0059] This embodiment of the utility model uses a thyristor group 210 and a voltage stabilization and filtering circuit 220 to rectify, stabilize, and filter the power distribution line 230 to power the energy storage module 120. A second current detection circuit 240 and a second voltage detection circuit 241 are used for real-time monitoring to ensure the safety of the power supply line. This utility model ensures a stable power supply for the energy storage module 120, improves overall energy utilization efficiency, and ensures the normal operation of the electromagnetic chuck 170 and other equipment.

[0060] Figure 3 Schematic diagram of another electromagnetic chuck control device according to an embodiment of the present invention. Figure 3 As shown, the electromagnetic chuck control device further includes: a first control power supply 310 , the input end of the first control power supply 310 is connected to the power distribution line 230 , and the output end of the first control power supply 310 is connected to the power interface of the main controller 110 .

[0061] Specifically, the first control power supply 310 refers to a device responsible for converting the input power of the distribution line 230 into the stable voltage and current required by the main controller 110, which usually includes functions such as rectification, voltage stabilization and filtering to ensure the quality and reliability of the output power.

[0062] In the embodiment of the present invention, the first control power supply 310 provides a stable power output through voltage stabilization and filtering functions, which can effectively prevent power fluctuations and noise from damaging the main controller 110 and extend its service life.

[0063] Continue to see Figure 3 Optionally, based on the above embodiments, the electromagnetic suction cup control device also includes a second control power supply 320, the input end of the second control power supply 320 is connected to the energy storage module 120, and the output end of the second control power supply 320 is connected to the power interface of the main controller 110.

[0064] Specifically, the second control power supply 320 refers to the device in the electromagnetic suction cup control device that is responsible for converting the power provided by the energy storage module 120 into the stable voltage and current required by the main controller 110, which can ensure that the main controller 110 can still obtain a reliable power supply in the event of a factory power outage or other unexpected situations.

[0065] In this embodiment of the present invention, the second control power supply 320, through voltage stabilization and filtering, effectively protects the main controller 110 from power fluctuations and noise, thereby extending its service life. Furthermore, the second control power supply 320 provides a redundant power supply solution, ensuring that the electromagnetic chuck control device can continue to operate even if a factory power supply problem or other malfunction occurs, thereby improving the overall reliability of the device.

[0066] Continue to see Figure 3 Optionally, based on the above embodiments, the first switch 130 includes a relay, and the second switch 140 includes a contactor.

[0067] Specifically, a relay is an electrical control device that uses electromagnetic principles to control the on / off state of a circuit by switching current. A relay typically has a control terminal and a load terminal. When the control terminal receives a signal, it closes or opens the circuit at the load terminal. Examples of relays include electromagnetic relays and solid-state relays.

[0068] A contactor is an electrical switch designed specifically to control high-power circuits. It typically consists of an electromagnet, contacts, and a mechanical structure. It enables rapid switching operations on power loads.

[0069] In this embodiment of the present invention, the relay can safely switch high-power loads under low-power control signals, providing electrical isolation and preventing the high voltage of the energy storage module 120 from affecting the main controller 110. The contactor can effectively isolate the control circuit from the high-power circuit. Since the electromagnetic chuck 170 typically requires high current and voltage to generate sufficient holding force, the contactor, as a high-power switch, can provide electrical isolation and ensure safety between the electromagnetic chuck controller 180 and the electromagnetic chuck 170.

[0070] The embodiment of the present invention ensures that the main controller 110 obtains a stable power supply through the coordinated operation of the first control power supply 310 and the second control power supply 320. On the other hand, it provides a backup power supply solution to ensure that the main controller 110 can obtain a continuous power supply, thereby effectively improving the reliability, safety and working efficiency of the electromagnetic suction cup control device.

[0071] Figure 4 Schematic diagram of another electromagnetic chuck control device according to an embodiment of the present invention. Figure 4As shown, the electromagnetic chuck control device further includes: an inverter 410 , a power supply end of the inverter 410 connected to the energy storage module 120 , a control end of the inverter 410 connected to the main controller 110 , and an output end of the inverter 410 connected to the brake motor 420 .

[0072] Specifically, the inverter 410 is a power electronic device that converts DC power into AC power. In the electromagnetic chuck control device, the inverter 410 converts the DC power provided by the energy storage module 120 into the required AC power to drive the brake motor 420 or other loads.

[0073] The brake motor 420 is an electric motor with a braking function, typically used in applications that require maintaining a fixed position. In equipment such as cranes and elevators, if the motor stops or loses power, the brake motor 420 stabilizes the load and prevents it from sliding down. In the electromagnetic chuck control device, the brake motor 420, under the control of the inverter 410, is responsible for providing the necessary torque to maintain the stability of the electromagnetic chuck 170 during operation.

[0074] For example, if the power supply of the factory where the electromagnetic suction cup control device is located suddenly fails, the DC power output by the energy storage module 120 can be converted into AC power through the inverter 410 to drive the brake motor 420 to open and lower the items sucked by the electromagnetic suction cup 170 to the ground.

[0075] Continue to see Figure 4 , optionally, based on the above embodiments, as Figure 4 As shown, the electromagnetic chuck control device further includes: a command input module 430 , and the command input module 430 is connected to the main controller 110 .

[0076] Specifically, command input module 430 is a device that provides an operating interface for the user and is used to receive user commands or control signals to control the operating state of electromagnetic chuck 170. For example, command input module 430 can input an excitation control signal or a field-weakening control signal. The excitation control signal is used to control electromagnetic chuck 170 to operate at full power, while the field-weakening control signal is used to control electromagnetic chuck 170 to operate at low power, to accommodate different application scenarios.

[0077] During actual operation, a corresponding magnetization delay should be set during the initial excitation phase. This is because the voltage of the electromagnetic chuck 170 takes time to rise after receiving the excitation control signal. This delay prevents the first voltage detection circuit 150 or the first current detection circuit 160 from detecting low voltage or current, which could cause the electromagnetic chuck control device to malfunction. Furthermore, when the first voltage detected by the first voltage detection circuit 150 falls below a set threshold, the magnetization operation is initiated, i.e., the energy storage module 120 is used to power the electromagnetic chuck control device. However, since the voltage of the electromagnetic chuck 170 is low when operating at low power, this could potentially cause malfunction of the magnetization operation. Therefore, the threshold for the first detection voltage is set below the magnetization voltage to prevent malfunction.

[0078] This embodiment of the utility model utilizes an inverter 410, a brake motor 420, and a command input module 430 to enable the energy storage module 120 to provide backup power for the electromagnetic chuck control device. Furthermore, a human-computer interaction module is provided to intuitively control the electromagnetic chuck control device, making it adaptable to various application scenarios. This utility model improves the reliability, safety, and flexibility of the electromagnetic chuck control device.
