Description

Technical Field

[0001] This invention relates to the field of magnetic blowout switch technology, and in particular to a synchronous on / off detection device for a magnetic blowout switch. Background Technology

[0002] A magnetic blow-out switch is an electrical component that uses the principle of electric arc magnetic blow-out for on / off control. Its on / off performance and synchronization directly affect the overall protection reliability of the device. Existing magnetic blow-out switch synchronization detection devices mostly combine mechanical clamping, electrical on / off testing, and constant-speed triggering. While these methods can achieve basic switch action detection, they still have shortcomings in detecting the synchronization of multi-layer stacked magnetic blow-out switches.

[0003] like Figure 1 and Figure 2 As shown in the figure, and in the prior art, the magnetic blow-out switch shown in the Chinese patent document with announcement number CN221507987U, both are magnetic blow-out switch bodies, whose top and bottom can be connected in series. When the magnetic blow-out switch body at the bottom is turned on or off, it can drive one or more magnetic blow-out switch bodies to be turned on or off synchronously.

[0004] Existing testing equipment generally employs fixed-stroke or manually adjustable clamping structures, and most are only two-wire electrical testing devices. The internal resistance of the wires and clamps drifts during testing due to temperature and contact wear, leading to inconsistent electrical signal judgment edges, insufficient inter-layer timestamp accuracy, poor repeatability of on / off synchronization test results, and a lack of bypass judgment mechanisms for individual clamping anomalies, easily causing misjudgments or duplicate tests in the entire batch. Furthermore, their fixed rotation speed and single triggering method make it impossible to simulate multiple triggering states within a single testing cycle. Triggers from different layers often complete within the same time period, resulting in the superposition of mechanical coupling and electromagnetic interference, reducing time difference resolution. Moreover, the lack of corner position feedback and phase correction mechanisms means that when the motor load changes, trigger phase drift accumulates, causing large statistical errors in inter-layer time difference and unstable synchronization indicators. Therefore, this application discloses a magnetic blow-out switch synchronous on / off detection device. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a magnetic blow-out switch synchronous on / off detection device to solve the problems of existing magnetic blow-out switch detection equipment, which mostly adopts a clamping structure with fixed stroke or manual adjustment and a two-wire detection method, lacking closed-loop control and corner position feedback. This leads to contact resistance drift, unstable trigger phase, and coupling interference caused by simultaneous triggering of multiple layers, resulting in inconsistent on / off signal edge judgment, low accuracy of inter-layer time difference, poor repeatability of synchronization detection results, and easy misjudgment.

[0006] To achieve the above objectives, the present invention provides a magnetic blow-out switch synchronous on / off detection device, comprising: a detection platform and a control panel disposed on one side of the detection platform, wherein the control panel is provided with a touch screen and a start switch, and the top surface of the detection platform is provided with a platform plate.

[0013] Preferably, both the bottom placement plate and the top placement plate are provided with a plurality of threaded holes, and the plurality of threaded holes are respectively adapted to the mounting holes on both sides of the magnetic blow-out switch body.

[0014] Preferably, the clamping detection assembly includes a vertical plate fixedly installed on one side of the support frame. The top and middle parts of the vertical plate are respectively provided with two first electric sliders and two second electric sliders. The two first electric sliders and the two second electric sliders are arranged opposite to each other. A plurality of clamping detection rods are provided on the opposite surfaces of the two first electric sliders and the two second electric sliders. The plurality of clamping detection rods respectively contact the contacts on both sides of the magnetic blow-out switch body.

[0015] Preferably, the triggering assembly includes a rotating shaft rotatably mounted in the middle of the support frame, and a plurality of trigger rings are fixedly sleeved on one outer surface of the rotating shaft, the plurality of trigger rings being used to contact the trigger block.

[0016] Preferably, the trigger rings are set as irregular circles, and the trigger rings are provided with irregular protrusions and grooves. The trigger rings are arranged in an alternating manner, and the irregular trigger rings are used to simulate different trigger states and trigger environments.

[0017] Preferably, the drive assembly includes a drive motor fixedly mounted on one side of the platform, a lead screw fixedly connected to the output end of the drive motor, a sliding block threaded onto the lead screw, a sliding plate slidably mounted on the sliding block, a U-shaped plate fixedly mounted on the sliding plate, a moving rod slidably mounted on one side of the support frame, a meshing gear fixedly sleeved on one side of the rotating shaft, a plurality of meshing teeth on one side of the moving rod meshing with the meshing gear, a drive plate fixedly sleeved on one side of the moving rod, and the drive plate slidably embedded in the U-shaped port of the U-shaped plate. When the drive motor drives the lead screw to rotate forward and backward, the sliding block moves back and forth horizontally on the lead screw, thereby driving the moving rod to drive the meshing gear to rotate and trigger the trigger ring.

[0018] Preferably, a cylinder is provided on one side of the top of the sliding block, and the telescopic end of the cylinder is fixedly connected to the sliding plate. When the sliding block extends or retracts, it drives the sliding plate to move horizontally on the sliding block, thereby pushing the drive plate to drive the moving rod to deflect. The drive plate slides at the U-shaped port of the U-shaped plate, driving the meshing teeth of the moving rod to deflect and disengage from the meshing gear.

[0019] Preferably, the control system includes a clamping detection control module, which is configured to:

[0020] Before the triggering component is activated, the first electric slider and the second electric slider are driven to bring several clamping detection rods closer together in a three-segment trajectory of pre-pressure-detection-stabilization and clamp the two side contacts of the magnetic blow-out switch body with the target pre-pressure.

[0021] During the clamping process, the contact resistance or current signal is collected in real time based on the detection circuit formed with the clamping detection rod, and the displacement of the first electric slider and the second electric slider is finely adjusted in a closed loop according to the rate of change, so that the contact is stabilized within the threshold range.

[0023] The clamping detection component uses a four-wire measurement system and sets up a reference circuit to compensate for the resistance between the wires and the clamp. When any clamping abnormality is detected, the motion coordination unit performs a delayed triggering and bypass determination on the clamping detection component.

[0024] Preferably, the control system further includes a triggering strategy module and an angular feedback unit. The angular feedback unit is used to acquire the angular information of the rotating shaft. The triggering strategy module is used to adaptively adjust the S-shaped speed curve of the drive motor and the initial phase of the rotating shaft according to the inter-layer time difference or consistency index of the previous cycle, and select different misaligned triggering time windows so that the triggering of several trigger rings for different layers falls into the time window in sequence. When no-load calibration or abnormal protection is required, the triggering strategy module controls the cylinder to drive the sliding plate to disengage the meshing teeth of the moving rod from the meshing gear for no-load positioning and reset, and then re-engages to resume detection.

[0025] The beneficial effects of this invention are:

[0026] 1. This magnetic blow-out switch synchronous on / off detection device, through the setting of a clamping detection component and a clamping detection control module, realizes multi-point clamping and "pre-pressure-detection-stabilization" closed-loop control. The four-wire system and reference circuit suppress contact internal resistance drift; stable electrical contact ensures consistent on / off edge judgment, significantly reduces timestamp error and cross-layer jitter, and makes the measurement of inter-layer time difference more accurate and repeatable. After triggering, the clamp release de-jitter ensures that the starting point of the next cycle is consistent, and the bypass of abnormal layers avoids sample contamination, thereby improving the reliability and convergence speed of synchronous detection.

[0027] 2. This magnetic blow-out switch synchronous on / off detection device, by setting up a trigger component in conjunction with a trigger strategy module and an angle feedback unit, utilizes an interleaved irregular trigger loop to act on each layer sequentially within the misaligned time window, significantly reducing instantaneous coupling interference and improving the synchronous detection resolution; the angle closed loop ensures the stability of the "angle-time" mapping, avoiding timing deviations caused by phase drift; the strategy adaptively adjusts the S-shaped velocity and initial phase based on the synchronous index of the previous cycle, continuously compressing the time difference between layers, making the synchronous result more stable and controllable.

[0028] 3. This magnetic blow-out switch synchronous on / off detection device, through the setting of a drive component and trigger strategy module, uses a graded transmission of motor-lead screw-slider-moving rod-meshing gear to stably convert linear displacement into a repeatable trigger angle position, providing consistent excitation for synchronization detection under a unified time base; cylinder disengagement supports load-free positioning and abnormal reset, maintains the zero phase baseline and eliminates accumulated errors; limit guidance and self-locking effect suppress hysteresis and vibration, reduce trigger time jitter, and enhance the comparability of cross-cycle synchronization statistics.

[0047] like Figures 1 to 13As shown, the magnetic blow-out switch synchronous on / off detection device includes a detection platform 3 and a control panel 4 disposed on one side of the detection platform 3. The control panel 4 is equipped with a touch screen 5 and a start switch 6. A platform 7 is disposed on the top surface of the detection platform 3. A placement component is disposed in the middle of the top surface of the platform 7 and is used to place several stacked magnetic blow-out switch bodies 1, wherein the bottom magnetic blow-out switch body 1 is connected to a trigger block 2 at its bottom end. A clamping detection component is disposed on both sides of the placement component and is used to clamp the two sides of the magnetic blow-out switch body 1 and connect to the two side contacts of the magnetic blow-out switch body 1 for detection. A trigger component is disposed in the middle of the placement component and is used to drive several sets of magnetic blow-out switch bodies 1 to perform synchronous on / off detection. A drive component is disposed on one side of the platform 7 and is used to drive the trigger component to perform rotation control. The control system is signal-connected to the touch screen 5 and the start switch 6, and is electrically connected to the clamping detection component, the trigger component, and the drive component. The control system includes a motion coordination unit, which is used to coordinate the drive component, the trigger component, and the... The timing sequence of the clamping detection component's operation is described, and a linkage strategy of delayed triggering, bypass control, and shutdown alarm is implemented for the corresponding component when an anomaly is detected. The control system is configured to: coordinate the drive component to drive the trigger component to operate according to a preset misalignment rhythm based on the detection parameters set on the control panel 4; collect the on / off signals of each layer of magnetic blow-out switch body 1 through the detection path connected to the clamping detection component, and allocate time markers for each layer's signals using the unified time base of the control system, calculate the inter-layer time difference and synchronization index, output the judgment result to the touch screen 5, and execute shutdown and alarm when an anomaly is detected. The placement assembly includes a positioning plate 8 fixedly installed on a platform 7. Fixing blocks 9 are provided on both sides of the platform 7 for fixing the positioning plate 8. A support frame 10 is provided on the positioning plate 8. A bottom placement plate 11 is provided on both sides of the top of the support frame 10. A top placement plate 12 is installed on the two bottom placement plates 11. The bottom placement plates 11 and the top placement plates 12 are used to fix the stacked magnetic blow-out switch body 1. A plurality of threaded holes 13 are provided on both the bottom placement plates 11 and the top placement plates 12. The plurality of threaded holes 13 are respectively adapted to the mounting holes on both sides of the magnetic blow-out switch body 1.

[0048] Specifically, the operator powers on the equipment, sets the number of layers to be tested, the misalignment drive rhythm, and the judgment threshold on the touch screen 5 of the control panel 4, and then presses the start switch 6. Subsequently, several stacked magnetic blow-out switch bodies 1 are placed on the placement assembly in the middle of the platform 7, and fixed through the threaded holes 13 of the bottom placement plate 11 and the top placement plate 12, and the mounting holes on both sides of the workpiece. The positioning plate 8 and the fixing block 9 ensure the stability of the reference position of the support frame 10 and the placement plate. After clamping, the control system commands the clamping detection assembly to approach from both sides and clamp the contacts on both sides of the magnetic blow-out switch body 1, establishing and stabilizing the detection path, and the system enters the standby state. When the operator confirms that everything is correct, a start detection command is issued, and the control system proceeds according to the pre-set parameters. The misaligned rhythm coordination drive component drives the trigger component to operate, causing each layer of magnetic blow-out switch body 1 to be triggered sequentially or according to a set misalignment relationship, resulting in on / off changes. The system collects the on / off signals of each layer in real time through the detection path connected to the clamping detection component, and assigns time markers to the signals of each layer with a unified time base. After the entire triggering process is completed, the control system calculates the time difference and synchronization index between layers based on the collected time markers, displays the qualified / unqualified results and related statistical values ​​on the touch screen 5, and saves the detection record of the current batch. If a detection abnormality is detected during the process, the system immediately stops and alarms, prompting the operator to handle the issue before continuing, thus completing a complete multi-layer superimposed magnetic blow-out switch on / off synchronization detection process.

[0049] like Figure 5 , Figure 7 , Figure 10 , Figure 12 As shown, the clamping detection assembly includes a vertical plate 14 fixedly installed on one side of the support frame 10. The top and middle parts of the vertical plate 14 are respectively provided with two first electric sliders 16 and two second electric sliders 17. The two first electric sliders 16 and two second electric sliders 17 are arranged opposite to each other. Several clamping detection rods 18 are provided on the opposite surfaces of the two first electric sliders 16 and two second electric sliders 17. The several clamping detection rods 18 are respectively in contact with the contacts on both sides of the magnetic blow-out switch body 1.

[0050] The control system includes a clamping detection control module, which is configured as follows:

[0051] Before the trigger component is activated, the first electric slider 16 and the second electric slider 17 are driven to make several clamping detection rods 18 approach each other along a three-stage trajectory of pre-pressure-detection-stabilization and clamp the two side contacts of the magnetic blow-out switch body 1 with the target pre-pressure.

[0052] During the clamping process, the contact resistance or current signal is collected in real time based on the detection circuit formed with the clamping detection rod 18, and the displacement of the first electric slider 16 and the second electric slider 17 is finely adjusted in a closed loop according to its rate of change, so that the contact is stabilized within the threshold range.

[0053] When the trigger component rotates to the preset angle range, the sampling is frozen and a timestamp is added to the on / off edge of each layer; after the trigger is completed, the reverse clamping and de-jittering micro-vibration operation is performed, and the target preload and approach speed of the next cycle are adaptively corrected according to the stability index of this test.

[0054] The clamping detection component uses a four-wire measurement system and sets up a reference circuit to compensate for the resistance of the wires and the clamp. When any clamping abnormality is detected, the motion coordination unit performs a delayed triggering and bypass judgment on the clamping detection component.

[0055] After the workpiece is fixed in place by the placement assembly, the clamping detection control module first drives the first electric slider 16 and the second electric slider 17 into the pre-pressure stage, causing several clamping detection rods 18 on both sides to approach each other at low speed and with small force until initial contact is established. Then, it enters the detection stage to continuously collect the detection loop signal formed by the clamping detection rods 18 and calculate the rate of change of contact resistance or current. If the rate of change exceeds the threshold, the displacement of the two pairs of electric sliders is slightly adjusted to achieve closed-loop fine adjustment until the contact stability meets the set conditions. Then, it enters the pressure stabilization stage to maintain clamping and stabilize the detection path with a constant target pre-pressure. The control system releases the trigger command under the pressure stabilization, and the trigger component starts to rotate according to the predetermined staggered rhythm. When it rotates to the preset angle interval, the system freezes the sampling window, stamps the timestamp of each layer's on / off edge with a unified time base, and continuously records until the triggering process ends. After the triggering is completed, the system immediately performs a reverse clamping action and superimposes a short-term de-jittering micro-vibration to release stress and remove small particles, and then returns to the standby clamping distance. If unstable contact or clamping abnormality is detected at any time, the motion coordination unit will... The control system performs delayed triggering and bypass judgment on this layer, while retaining the normal detection process of other layers and recording the abnormal layer identifier and log. When all layer data of this cycle is ready, the control system calculates the time difference and synchronization index between layers based on the timestamp, displays and archives the qualified / unqualified and abnormal information on the touch screen 5, and adaptively corrects the target pre-pressure and approach speed of the next cycle based on the stability index of this cycle, and enters the next detection cycle. Among them, the "rate of change" is used as a sensitive criterion to identify the subtle fluctuations in the contact state in advance, drive the first / second electric slider 17 to make a small displacement correction, so that the contact falls within the threshold band, significantly reducing false judgments (false opening / false short) and repeated tests. After triggering, the brief reverse clamping and superimposed micro-vibration can release the superimposed load of the workpiece and the fixture, clean the micro-chips / contamination on the contact surface and eliminate hysteresis, ensuring that the next cycle starts with a consistent initial state. In addition, when any layer clamping is abnormal, the motion coordination unit realizes delayed triggering and bypass judgment on this layer, without slowing down the detection of other layers, reducing the downtime losses of the entire batch.

[0056] like Figure 10 , Figure 11 , Figure 13As shown, the triggering assembly includes a rotating shaft 19 rotatably mounted in the middle of the support frame 10. A plurality of trigger rings 20 are fixedly sleeved on one outer surface of the rotating shaft 19. The plurality of trigger rings 20 are used to contact the trigger block 2. The plurality of trigger rings 20 are set as irregular circles, and the plurality of trigger rings 20 are provided with irregular protrusions and grooves. The plurality of trigger rings 20 are arranged in an alternating manner. The plurality of irregular trigger rings 20 are used to simulate different triggering states and triggering environments.

[0057] The control system also includes a triggering strategy module and an angular feedback unit. The angular feedback unit is used to obtain the angle information of the rotating shaft 19. The triggering strategy module is used to adaptively adjust the S-shaped speed curve of the drive motor 23 and the initial phase of the rotating shaft 19 according to the inter-layer time difference or consistency index of the previous cycle, and select different misaligned triggering time windows so that the triggering of several triggering rings 20 for different layers falls into the time window in sequence.

[0058] After powering on, the system sets the number of layers to be detected, the misalignment trigger time window for each layer, the target synchronization index, and the S-shaped rotation speed parameters via the touchscreen 5. Upon startup, the control system first reads the current angle from the angular feedback unit, aligns the phase of the rotating shaft 19 with the preset initial phase, and confirms that the relative positions of several trigger rings 20 and trigger blocks 2 are in the triggering zone. Then, the trigger strategy module sends an S-shaped rotation speed curve to the drive motor 23. The motor drives the rotating shaft 19 to smoothly accelerate into the detection speed. The angular feedback unit continuously outputs angle information, and the strategy module compares the correspondence between the time window and the angular position in real time. When the angle enters the misalignment time window assigned to a certain layer, it ensures that the protruding section of the corresponding trigger ring 20 contacts the trigger block 2 and remains in the set dwell position. When it leaves the time window or reaches the set angular threshold, it smoothly disengages to avoid overshoot. Within the same rotation cycle, several irregularly arranged trigger rings 20 are sequentially triggered with each layer, forming different trigger patterns and dwell times. The control system records the on / off edge timestamps of each layer within the corresponding time window in parallel. After the cycle ends, the strategy module uses the timestamps... The interlayer time difference and consistency index are calculated, and the results are displayed on the touch screen 5 and saved. If the time difference of a certain layer is found to be continuously large or the fluctuation exceeds the threshold, the strategy module automatically adjusts the angular position and dwell ratio of the corresponding time window of that layer in the next cycle without changing the mechanism. At the same time, it fine-tunes the S-curve of the motor (such as the lifting time, constant speed section length and deceleration time) and the initial phase of the rotating shaft 19 to make the triggering of that layer closer to the target synchronization range. Then, the above process is repeated in the next cycle until the set synchronization index is reached or the predetermined test rounds are completed. Among them, several trigger rings 20 are irregular circles with protrusions / grooves and are interlaced. They can form different contact trajectories and trigger "dwelling times" in one rotation cycle, which equivalently simulates different triggering states and triggering environments (such as light touch / heavy touch, fast touch / slow touch, short dwell / long dwell). A set of mechanisms completes multi-condition evaluation. The trigger rings 20 are arranged in an interlaced manner. With the self-correction of the initial phase, the geometric manufacturing / clamping error can be absorbed in the phase adjustment, reducing the dependence on high-precision mechanical consistency and making long-term operation more stable.

[0059] like Figure 5 , Figure 6 , Figure 13As shown, the drive assembly includes a drive motor 23 fixedly mounted on one side of the platform 7. A lead screw 24 is fixedly connected to the output end of the drive motor 23. A sliding block 25 is threaded onto the lead screw 24. A sliding plate 27 is slidably mounted longitudinally on the sliding block 25. A U-shaped plate 28 is fixedly mounted on the sliding plate 27. A moving rod 22 is slidably mounted on one side of the support frame 10. A meshing gear 21 is fixedly sleeved on one side of the rotating shaft 19. A plurality of meshing teeth are provided on one side of the moving rod 22 to mesh with the meshing gear 21. A drive plate 29 is fixedly sleeved on one side of the moving rod 22. The drive plate 29 is slidably embedded in the U-shaped port of the U-shaped plate 28. When the drive motor 23 drives the lead screw 24 to rotate forward and backward, the sliding block 25 moves back and forth horizontally on the lead screw 24. The movement drives the moving rod 22 to drive the meshing gear 21 to rotate, which in turn drives the trigger ring 20 to trigger. A cylinder 26 is provided on one side of the top of the sliding block 25. The telescopic end of the cylinder 26 is fixedly connected to the sliding plate 27. When the sliding block 25 extends or retracts, the sliding plate 27 is driven to move horizontally on the sliding block 25, which in turn pushes the drive plate 29 to drive the moving rod 22 to deflect. The drive plate 29 slides at the U-shaped port of the U-shaped plate 28, and the meshing teeth of the moving rod 22 deflect to disengage from the meshing gear 21. When no-load calibration or abnormal protection is required, the trigger strategy module controls the cylinder 26 to drive the sliding plate 27 to disengage the meshing teeth of the moving rod 22 from the meshing gear 21 for no-load positioning and reset, and then re-engages to resume detection.

[0060] The control system first confirms that the current state is in engagement. At this time, the sliding plate 27 is embedded in the U-shaped port of the U-shaped plate 28, and the drive plate 29 drives the moving rod 22 to maintain reliable engagement with the meshing gear 21. Then, the drive motor 23 starts in the set direction and drives the lead screw 24 to rotate. The lead screw 24 drives the sliding block 25 to move smoothly in the horizontal direction. The sliding block 25 carries the sliding plate 27 on it to move synchronously. Since the sliding plate 27 and the drive plate 29 are fixedly connected, the drive plate 29 pushes the moving rod 22 to make linear drive along the guide and drives it through the meshing teeth on one side. The meshing gear 21 rotates, and is fixedly sleeved on the rotating shaft 19 to rotate synchronously, thereby driving the trigger ring 20 to contact and disengage from the trigger block 2 according to a set rhythm to form one triggering process; when the lead screw 24 continues to rotate to the end of its stroke, the control system reverses the direction, causing the drive motor 23 to reverse, and the sliding block 25 to return in the opposite direction, driving the moving rod 22 to make the meshing gear 21 rotate in the opposite direction, and the trigger ring 20 completes the next triggering segment according to the preset trajectory until a working cycle is completed; if it is necessary to enter the no-load calibration or if abnormal protection conditions occur (such as a certain floor needs to be calibrated), the trigger ring 20 will be activated. (If abnormal torque is detected or skipped), the triggering strategy module in the control system sends a command to cylinder 26. Cylinder 26 extends and retracts, causing its fixedly connected sliding plate 27 to move horizontally relative to the sliding block 25. This causes the drive plate 29 to slide within the U-shaped port of the U-shaped plate 28 and deflect the moving rod 22. As a result, the moving rod 22 disengages its meshing teeth from the meshing gear 21, and the power chain is momentarily disconnected. At this time, the drive motor 23 can continue to idle at low speed or stop to complete the no-load positioning and reset operation. After the calibration / protection steps are completed, cylinder 2... The reverse action resets the sliding plate 27 to the meshing position, and the drive plate 29 returns to the working area of ​​the U-shaped port. The moving rod 22 returns to the center and re-engages with the meshing gear 21, and the system returns to the working condition. Then, the control drive motor 23 drives the lead screw 24 again according to the set forward and reverse rhythm. The sliding block 25 reciprocates to push the moving rod 22, causing the meshing gear 21 and the rotating shaft 19 to rotate continuously. The trigger ring 20 completes the triggering action of each layer in sequence. At the same time, the control system continuously records the on / off signals and time information of the corresponding triggering stage until the batch test is completed.
