The outer wall of the fixed sleeve is movably connected to a limiting component, and the limiting component is used to improve the tightness when the plug body is connected to the line connector.

[0015] Preferably, the limiting assembly includes a group of slide grooves, and the slide grooves are opened on the outer wall of the fixed sleeve, the inner wall of the slide groove is movably connected with a slider, one end of the slider is penetrated by a fixed rod, and both ends of the fixed rod are installed on the inner wall of the slide groove, the outer wall of the fixed rod is movably connected with a pressure spring, and one end of the pressure spring is movably connected to one side of the slider.

[0016] Preferably, a limiting sleeve is installed at one end of the sliding block, and the inner wall of the limiting sleeve is movably connected to the outer wall of the arc-shaped connecting sleeve, and the outer wall of the limiting sleeve is provided with a frosted surface.

[0018] Preferably, the working steps of the electro-permanent magnetic chuck controller with rapid charging and demagnetization function are as follows:

[0019] S1. Detecting various key parameter data collected by the data acquisition module through the activation condition module to verify whether the temperature exceeds the threshold, the specific position of the electro-permanent magnetic chuck, and whether there is an object attached to the bottom, and other parameter data, thereby determining whether the activation conditions are met;

[0020] S2. Determine that the enabling conditions are met, generate accurate charging and demagnetization control signals based on various key parameter data collected by the data acquisition module through the microcontroller module, and accurately adjust the magnitude and rate of the charging and demagnetization current by adjusting the actuator through the PLC controller;

[0021] S3. If the activation conditions are not met, that is, if the temperature exceeds the threshold, the electro-permanent magnetic chuck is in a dangerous position, and an object is attached to the bottom, adjusting the magnitude and rate of the charging and demagnetization current may cause changes in temperature or magnetic force, which may damage the chuck controller or cause the object to be damaged or dropped due to increased or decreased magnetic force. Therefore, if the activation conditions are not met, the magnitude and rate of the charging and demagnetization current shall not be adjusted;

[0022] S4. By pulling the limit sleeve, the slider moves in the slide groove, and then the limit sleeve moves out of the range of the arc-shaped connecting sleeve. The plug body is inserted into the line connector, which can move the arc groove opened on the inner wall of the arc-shaped connecting sleeve to the outer wall of the limiting ring. The limit sleeve is released, and the elastic force of the pressure spring pushes the slider to move, and then pushes the limit sleeve to move, so that the limit sleeve moves back to the range of the arc-shaped connecting sleeve, which can limit the arc-shaped connecting sleeve, improve the stability of the connection between the plug body and the line connector, and thereby improve the stability of the transmission of power supply and charging and demagnetization control signals.

[0023] Preferably, the step S2 further includes the following steps:

[0024] S21. When the enabling conditions are met, in addition to being able to generate the charging and demagnetization control signals through the microcontroller module, the charging and demagnetization control signals can also be manually input through the control panel. In an emergency, the enabling condition module can be turned on or off by triggering the emergency control button. After the enabling condition module is turned off, the magnitude and rate of the charging and demagnetization current can still be adjusted even if the enabling conditions are not met, thereby improving the flexibility of the controller and facilitating the response to sudden emergencies.

[0025] The S3 also includes the following steps:

[0026] S31. When the temperature exceeds a threshold, the temperature change in the suction cup controller is monitored in real time by a temperature sensor, and the speed of the fan is adjusted according to the temperature change, thereby improving the temperature control effect of the controller;

[0027] S32. The first dust filter and the second dust filter can prevent dust from entering the interior of the suction cup controller during heat dissipation.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention uses an activation condition module to detect various key parameter data collected by the data acquisition module, thereby verifying parameter data such as whether the temperature exceeds a threshold, the specific position of the electro-permanent magnetic chuck, and whether an object is attracted to the bottom, and then determines whether the activation conditions are met. If the activation conditions are met, the microcontroller module can generate accurate charging and demagnetization control signals based on the various key parameter data collected by the data acquisition module. The PLC controller regulates the actuator to precisely adjust the magnitude and rate of the charging and demagnetization current, thereby improving the stability and efficiency of the charging and demagnetization process.

[0030] 2. If the activation condition module fails to meet the activation conditions, namely, if the temperature exceeds a threshold, the electro-permanent magnetic chuck is in a dangerous position, and an object is attracted to the bottom, the present invention adjusts the magnitude and rate of the magnetization and demagnetization current. This can cause temperature or magnetic force fluctuations, which in turn can damage the chuck controller or cause objects to be damaged or dropped due to increased or decreased magnetic force. Therefore, if the activation conditions are not met, the magnitude and rate of the magnetization and demagnetization current are prohibited from being adjusted. The fan speed is adjusted to improve the cooling effect, thereby protecting the entire controller.

[0031] 3. When the activation conditions are met, the present invention not only generates the charging and demagnetization control signals through the microcontroller module, but also allows manual input of the charging and demagnetization control signals through the control console. In an emergency, the activation condition module can be activated or deactivated by triggering the emergency control button. After deactivating the activation condition module, the magnitude and rate of the charging and demagnetization current can still be adjusted even if the activation conditions are not met, thereby improving the controller's flexibility and facilitating response to sudden emergencies.

[0032] 4. The present invention drives the slider to move within the slide groove by pulling the limit sleeve, thereby moving the limit sleeve out of the range of the arc-shaped connecting sleeve. When the plug body is inserted into the line connector, the arc groove formed on the inner wall of the arc-shaped connecting sleeve can be moved to the outer wall of the limiting ring. When the limit sleeve is released, the elastic force of the pressure spring pushes the slider to move, thereby pushing the limit sleeve to move back to the range of the arc-shaped connecting sleeve. This can restrict the arc-shaped connecting sleeve, improve the stability of the connection between the plug body and the line connector, and further improve the stability of the transmission of power supply and charging and demagnetization control signals.

[0061] S3. If the activation conditions are not met, that is, if the temperature exceeds the threshold, the electro-permanent magnetic chuck 8 is in a dangerous position, and an object is attracted to the bottom, adjusting the magnitude and rate of the charging and demagnetization current may cause changes in temperature or magnetic force, thereby damaging the chuck controller 7 or causing the object to be damaged or dropped due to increased or decreased magnetic force. Therefore, if the activation conditions are not met, adjusting the magnitude and rate of the charging and demagnetization current is prohibited.

[0062] S4. By pulling the limit sleeve 28, the slider 24 is driven to move in the slide groove 23, and then the limit sleeve 28 is moved out of the range of the arc-shaped connecting sleeve 18.

[0063] S2 also includes the following steps:

[0064] S21. When the enabling conditions are met, in addition to generating the charging and demagnetization control signals through the microcontroller module 1, the charging and demagnetization control signals can also be manually input through the control console 13. In an emergency, the enabling condition module 5 can be turned on or off by triggering the emergency control button 15.

[0065] S3 also includes the following steps:

[0066] S31. When the temperature exceeds a threshold, the temperature sensor 11 monitors the temperature change in the suction cup controller 7 in real time, and adjusts the speed of the fan 35 according to the temperature change, thereby improving the temperature control effect of the controller;

[0067] S32. The first dustproof filter 34 and the second dustproof filter 38 can prevent dust from entering the interior of the suction cup controller 7 under heat dissipation.

[0068] Working principle: Through the enabling condition module 5, various key parameter data collected by the data acquisition module 2 are detected, and then the parameter data such as whether the temperature exceeds the threshold, the specific position of the electro-permanent magnetic chuck 8 and whether there are objects adsorbed on the bottom are verified, and then whether the enabling condition is met. After the enabling condition is determined to be met, the micro-control module 1 can generate accurate charging and demagnetization control signals according to various key parameter data collected by the data acquisition module 2, and the PLC controller 3 adjusts the actuator 4 to accurately adjust the size and rate of the charging and demagnetization current, thereby improving the stability and efficiency of the charging and demagnetization process. If the enabling condition module 5 does not meet the enabling condition, that is, the temperature exceeds the threshold, the micro-control module 1 will generate accurate charging and demagnetization control signals according to various key parameter data collected by the data acquisition module 2, and the PLC controller 3 adjusts the actuator 4 to accurately adjust the size and rate of the charging and demagnetization current, thereby improving the stability and efficiency of the charging and demagnetization process. When the threshold is exceeded, the electro-permanent magnetic suction cup 8 is in a dangerous position and there are objects adsorbed on the bottom, adjusting the magnitude and rate of the charging and demagnetization current can cause changes in temperature or magnetic force, thereby causing damage to the suction cup controller 7 or damage or falling of objects due to increased or decreased magnetic force. Therefore, when the activation conditions are not met, it is prohibited to adjust the magnitude and rate of the charging and demagnetization current, which can protect the entire controller. When the activation conditions are met, in addition to generating the charging and demagnetization control signal through the micro-control module 1, the charging and demagnetization control signal can also be manually input through the control console 13. Through the emergency control button 15, in an emergency, In an emergency, the enabling condition module 5 can be turned on or off by triggering the emergency control button 15. After the enabling condition module is turned off, even if the enabling condition is not met, the size and rate of the charging and demagnetizing current can still be adjusted, which is conducive to improving the flexibility of the controller and facilitating the response to sudden emergency situations. By pulling the limit sleeve 28, the slider 24 is driven to move in the slide groove 23, and then the limit sleeve 28 is moved out of the range of the arc-shaped connecting sleeve 18. The plug body 22 is inserted into the line connector 16, which can make the arc groove 19 on the inner wall of the arc-shaped connecting sleeve 18 move to the outer wall of the limiting ring 17.

Determine that the enabling conditions are met, generate accurate charging and demagnetization control signals based on various key parameter data collected by the data acquisition module through the microcontroller module, and accurately adjust the magnitude and rate of the charging and demagnetization current by adjusting the actuator through the PLC controller; S3. If the activation conditions are not met, that is, if the temperature exceeds the threshold, the electro-permanent magnetic chuck is in a dangerous position, and an object is attached to the bottom, adjusting the magnitude and rate of the charging and demagnetization current may cause changes in temperature or magnetic force, which may damage the chuck controller or cause the object to be damaged or dropped due to increased or decreased magnetic force.
