Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new material detection, in particular to a silicon steel stripping layer online detection device and detection method. BACKGROUND

[0002] As a core soft magnetic functional material in the field of power electronics, silicon steel is widely used in the manufacturing of transformer and motor cores. The structure integrity of the insulating coating on the surface of the silicon steel directly determines the insulation resistivity, magnetic hysteresis loss characteristics and overall service life of the core. The coating stripping defect and micro-crack defect are the core defect types affecting the quality of silicon steel products, which need to be identified and controlled in real time by an online detection device.

[0003] After the existing insulating coating on the surface of the silicon steel is sprayed and solidified, it is cooled by a forced cooling system and then wound by a winding machine for storage. In the downstream processing stage, the silicon steel coil is unwound by an unwinding machine, adjusted in posture by a tension control system and a flattening unit, and then conveyed to subsequent processing equipment. In the unwinding and conveying process, a visual detection device is used in cooperation with a special lighting system to detect micro-cracks and stripping defects on the surface of the coating at a fixed detection height. The detection height of the visual detection device is fixed, and the relative positions of the lighting system and the imaging module also remain unchanged.

[0004] Although the flattening unit is arranged to flatten the unwound silicon steel, the internal stress accumulated in the silicon steel substrate during the rolling process will be released when it is unwound, and there is a difference in the thermal expansion coefficient between the coating and the substrate, which causes local elastic recovery deformation after flattening. The deformation is non-uniform, which causes the actual detection distance between the visual detection device with a fixed detection height and the dynamic surface of the silicon steel to fluctuate in a small range, resulting in unclear imaging in some areas. In addition, for local areas with large curvature on the surface of the silicon steel, the incident angle of the lighting system at a fixed position and the collection angle of the imaging system cannot cover the area, thus forming a detection blind area, which seriously affects the accuracy of product quality detection.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0043] Please refer to Figures 1 to 11 The present application provides an embodiment as shown in the figure:

[0044] The application discloses a silicon steel stripping layer on-line detection device and a detection method.

[0045] In actual application, as shown in the drawings, Figure 1 The silicon steel to be detected is first fed by the feeding seat 1, so that the silicon steel is smoothly fed into the connecting seat 2 fixedly installed between the feeding seat 1 and the discharging seat 3, at this time, the silicon steel is in the action area of the flattening assembly 5 in the connecting seat 2, and the surface coating of the silicon steel faces the detection assembly 4 side, so that the initial posture is prepared for the subsequent flattening and detection procedures.

[0046] As shown in the drawings, Figure 2 、 Figure 8 and Figure 10 When the silicon steel enters the preset position of the connecting seat 2, the driving mechanism 54 outputs power, drives the two traction seats 51 installed in the connecting seat 2 through the transmission rods 59 fixedly connected to the two ends of the traction seat 51, and drives the two traction seats 51 installed in the connecting seat 2 through the synchronous mechanism 55, so that the synchronization and stability of the movement of the two traction seats 51 are ensured, and the movement track of the traction seat 51 is further stabilized. In this process, the traction seat 51 forms a clamping force on the silicon steel, and the pre-clamping action of the clamping mechanism 52 is combined, so that the traction seat 51 applies a traction force to the silicon steel through the same direction movement after facing each other, the residual deformation of the silicon steel caused by unwinding is controlled to deform plastically, the flattening and correction of the surface of the silicon steel are realized, the surface of the silicon steel to be detected is ensured to be in an approximately planar state, and the appearance interference is eliminated for the subsequent accurate detection.

[0047] As shown in the drawings, Figure 2 and Figure 3As shown, after the flattened silicon steel is conveyed to the detection station directly below the detection assembly 4, the vision detection unit 45 fixedly installed inside the movable frame 42 detects the initial defects of the surface coating of the silicon steel, preliminarily identifies the approximate positions of defects such as coating peeling layer and micro-cracks; at the same time, the vision detection unit 45 collects real-time distance data between the surface of the silicon steel and the vision detection unit 45 based on the image ranging principle, and transmits the distance data to the controller;

[0048] After the controller receives the distance data transmitted by the vision detection unit 45, it compares the preset optimal detection distance, i.e. the optimal distance between the vision detection unit 45, the electromagnetic probe 44 and the surface of the silicon steel. If there is a deviation between the actual distance and the optimal detection distance, the controller sends a driving signal to the motor one 43 fixedly installed at the top of the support 41. After receiving the signal, the motor one 43 starts and its output end drives the threaded rod 47 to rotate synchronously through the coupling. Since the threaded rod 47 and the threaded sleeve 46 fixedly installed at the top of the movable frame 42 are in threaded connection, and the movable frame 42 is slidingly installed inside the support 41, the support 41 radially constrains the movable frame 42, limiting its rotational freedom. The rotational movement of the threaded rod 47 is converted into the axial linear movement of the threaded sleeve 46, which in turn drives the movable frame 42 to slide along the inside of the support 41, achieving the height adjustment of the movable frame 42, until the distance between the surface of the silicon steel and the vision detection unit 45, the electromagnetic probe 44 reaches the optimal detection distance.

[0049] After the height adjustment of the movable frame 42 is completed, the electromagnetic probe 44 fixedly installed inside the movable frame 42 emits electromagnetic signals of a specific frequency to the surface coating of the silicon steel based on the principle of electromagnetic induction. When there is a coating peeling layer on the surface of the silicon steel, the permeability and resistivity of the peeling layer area are significantly different from those of the normal coating area, causing a sudden change in the electromagnetic induction feedback signal received by the electromagnetic probe 44. The electromagnetic probe 44 transmits the feedback signal to the controller, which analyzes and processes the signal, combines with the preliminary detection results of the vision detection unit 45, and accurately determines the position, area and other parameters of the coating peeling layer on the surface of the silicon steel, completing the accurate detection of the silicon steel peeling layer.

[0050] As shown in Figure 1 , the silicon steel after completing the peeling layer detection continues to be conveyed from the connecting seat 2 inside to the discharging seat 3 under the traction of the flattening assembly 5, and the discharging seat 3 completes the collection or subsequent conveying of the silicon steel after detection, thus completing the online detection process of the single-section silicon steel, effectively eliminating the influence of residual deformation of the silicon steel on the detection accuracy and ensuring the accuracy of defect identification.

[0051] As shown in Figure 4 , Figure 5 , Figure 8 and Figure 10As shown, the driving mechanism 54 comprises a support seat 541, a driving seat 542 and a driving shaft 543, the support seat 541 is fixedly installed on the top of the connecting seat 2, the driving shaft 543 is rotatably connected to the inside of the support seat 541, the driving seat 542 is fixedly connected with the driving shaft 543, and the transmission rod 59 is slidingly installed in the inside of the driving seat 542.

[0052] The outside of the support seat 541 is fixedly installed with a motor two 6, and the output end of the motor two 6 is fixedly connected with the driving shaft 543 through a shaft coupling.

[0053] When the traction seat 51 needs to be driven to move in actual application, the motor two 6 fixedly installed on the outside of the support seat 541 is started, and the output end of the motor two 6 transmits torque to the driving shaft 543 rotatably connected to the inside of the support seat 541 through a shaft coupling, so that the driving shaft 543 rotates synchronously, and since the driving seat 542 is fixedly connected with the driving shaft 543, the rotation of the driving shaft 543 directly drives the driving seat 542 to rotate synchronously.

[0054] At this time, the transmission rod 59 slidingly installed in the inside of the driving seat 542 converts the rotation of the driving seat 542 into directional sliding along the gap formed between the support seat 541 and the connecting seat 2 under the rotation driving force of the driving seat 542, and the movement of the transmission rod 59 is synchronously transmitted to the traction seat 51 fixedly connected therewith, so that the displacement driving of the traction seat 51 is finally realized, and the clamping and traction of the silicon steel are realized.

[0055] As shown in Figure 5 , Figure 8 and Figure 9 , the synchronous mechanism 55 comprises a mounting seat 551, a back plate 552 and a guide seat 557, the back plate 552 is fixedly connected to one end of the mounting seat 551 away from the traction seat 51, the guide seat 557 is fixedly installed on the inner wall of the connecting seat 2, the back plate 552 is slidingly connected with the guide seat 557, the inside of the mounting seat 551 is slidingly connected with an upper seat 554 and a lower seat 553, the upper seat 554 is fixedly connected with the transmission rod 59, the inside of the back plate 552 is fixedly connected with a mounting shaft 556, the outside of the mounting shaft 556 is rotatably connected with a gear two 555, the inside of the lower seat 553 and the upper seat 554 is respectively fixedly connected with a rack 558, and the two racks 558 are symmetrically distributed and engaged with the gear two 555.

[0056] The outside of the back plate 552 is fixedly connected with a connecting block 57, and the outside of the connecting block 57 is fixedly connected with a driving strip 58.

[0057] In actual application, when the driving mechanism 54 drives the transmission rod 59 to produce linear displacement, the upper seat 554 fixedly connected with the transmission rod 59 moves synchronously with the transmission rod 59, since the upper seat 554 is slidingly installed in the installation seat 551, the installation seat 551 moves synchronously with the upper seat 554, at this time, the installation seat 551 moves away from the back plate 552 fixedly connected with one end of the traction seat 51, and slides along the guide seat 557 fixedly installed on the inner wall of the connecting seat 2, the guide seat 557 forms radial constraint on the movement track of the installation seat 551 and the upper seat 554 through the sliding cooperation with the back plate 552, effectively inhibits the rotation or deviation of the upper seat 554 in the moving process, and further guarantees the movement stability of the traction seat 51 associated with the upper seat 554, avoids the influence of the posture deviation of the traction seat 51 on the flattening effect of the silicon steel;

[0058] In the process that the upper seat 554 slides along the installation seat 551, the rack 558 fixedly connected in the upper seat 554 moves synchronously, since the rack 558 is engaged with the gear two 555 rotatingly connected with the outside of the installation shaft 556 in the back plate 552, the linear movement of the rack 558 is converted into the rotary movement of the gear two 555, at the same time, the lower seat 553 slidingly connected in the installation seat 551 is symmetrically engaged with the gear two 555 fixedly installed in the inside, the gear two 555 drives the lower seat 553 to produce synchronous displacement in the opposite direction of the upper seat 554 with the same speed, finally realizes the symmetrical opening and closing action of the two traction seats 51, ensures the uniform distribution of the clamping force on the silicon steel, and avoids the new deformation of the silicon steel due to the uneven clamping stress;

[0059] When the back plate 552 moves with the installation seat 551, the connecting block 57 fixedly connected with the outside of the back plate 552 synchronously drives the driving strip 58 to displace, the driving strip 58 transmits the movement power of the synchronous mechanism 55 to the clamping mechanism 52 through the engagement with the gear one 526 in the clamping mechanism 52, provides power basis for the clamping mechanism 52 to realize the pre-clamping and surface cleaning of the silicon steel, and ensures the traction flattening of the traction seat 51 and the pre-clamping action of the clamping mechanism 52 to be synchronous.

[0060] As Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, the clamping mechanism 52 comprises a clamping block 521, a connecting sleeve 522 and a movable seat 523, the connecting sleeve 522 is symmetrically fixedly connected to the outer side of the clamping block 521, the movable seat 523 is slidingly installed in the inner part of the connecting seat 2 through a guide plate 529, a connecting rod 524 is rotatably connected between the clamping block 521 and the movable seat 523, a lead screw 525 is rotatably installed in the inner part of the connecting seat 2, the lead screw 525 is threadedly connected between the movable seat 523, and the outer side of the lead screw 525 is fixedly connected with a gear one 526, and the top of the driving bar 58 is provided with gear teeth matched with the gear one 526.

[0061] The inner part of the connecting sleeve 522 is slidingly connected with a cleaning block 527 through a pin block, and the spring 528 is symmetrically fixedly connected between the cleaning block 527 and the inner wall of the connecting sleeve 522.

[0062] In actual application, when the synchronous mechanism 55 drives the displacement of the driving bar 58, the gear teeth on the top of the driving bar 58 are engaged with the gear one 526 fixedly connected to the outer side of the lead screw 525, the linear motion of the driving bar 58 is converted into the rotary motion of the gear one 526, and then the synchronous rotation of the lead screw 525 fixedly connected with the gear one 526 is driven, the lead screw 525 is rotatably installed in the inner part of the connecting seat 2, and the stability of the rotation axis is ensured, since the lead screw 525 is threadedly connected with the movable seat 523, and the movable seat 523 is constrained by the guide plate 529 and cannot rotate with the lead screw 525, the rotary motion of the lead screw 525 is converted into the linear displacement of the movable seat 523 along the axial direction of the lead screw 525, and the opposite or reverse movement of the movable seat 523 at both ends is realized.

[0063] When the movable seat 523 at both ends moves towards each other, the movable seat 523 applies a pushing force to the clamping block 521 through the rotatably connected connecting rod 524, the connecting rod 524 adaptively adjusts the angle through its rotation, converts the axial force of the movable seat 523 into the radial clamping force of the clamping block 521, and pushes the clamping block 521 to move close to the surface of the silicon steel, along with the displacement of the clamping block 521, the symmetrically fixed connecting sleeve 522 on the outer side of the clamping block 521 moves synchronously, and finally the cleaning block 527 in the inner part of the connecting sleeve 522 contacts the surface of the silicon steel, forming a pre-clamping constraint on the silicon steel, providing a stable clamping basis for the flattening and correction of the silicon steel by the traction seat 51 in the subsequent traction.

[0064] After the cleaning block 527 contacts the silicon steel, the springs 528 symmetrically arranged between the inner wall of the connecting sleeve 522 and the cleaning block 527 are compressed, and the elastic reaction force of the springs 528 acts on the cleaning block 527, on the one hand, it ensures that the cleaning block 527 always adheres to the surface of the silicon steel, and removes the foreign matter and loose and bulging defects on the surface of the silicon steel coating through the material properties of the cleaning block 527; on the other hand, the elastic deformation of the spring 528 can adaptively buffer the slight deformation of the surface of the silicon steel, avoid the damage of the silicon steel coating caused by the excessive pre-clamping force, and ensure the stability of the pre-clamping force, so that the silicon steel does not slide relatively during the traction process, and the flattening effect is improved.

[0065] As Figure 2 , Figure 4 , Figure 10 And Figure 11 As shown, the inside of the driving roller 53 is rotatably installed with a driving rod 56 through a one-way bearing, the driving rod 56 is rotatably installed in the inside of the connecting seat 2, and the outside of the driving rod 56 is fixedly connected with a gear three 50, and the gear three 50 is in meshing engagement with the driving strip 58.

[0066] In actual application, when the synchronous mechanism 55 drives the driving strip 58 to move linearly, the driving strip 58 is in meshing transmission with the gear three 50 fixedly connected with the outside of the driving rod 56, the linear displacement of the driving strip 58 is converted into the rotary motion of the gear three 50, and then the driving rod 56 fixed with the gear three 50 is synchronously rotated, since the driving rod 56 is rotatably installed in the inside of the driving roller 53 through the one-way bearing, when the driving rod 56 rotates in the preset direction, the one-way bearing is in meshing force under the action of the driving rod 56 to drive the driving rod 56 and the driving roller 53 to form rigid connection, the rotary torque of the driving rod 56 is directly transmitted to the driving roller 53 to drive the driving roller 53 to rotate synchronously, and the driving of the silicon steel is realized; when the driving rod 56 reversely rotates, the one-way bearing is in a separated state, the driving rod 56 idles and cannot drive the driving roller 53 to rotate, so that it is ensured that the driving roller 53 only outputs driving force in the feeding direction of the silicon steel, the resistance of the driving roller 53 when the silicon steel reversely moves is avoided, and the one-way continuity and stability of the silicon steel conveying are ensured.

[0067] Another embodiment of the present application is provided:

[0068] A silicon steel stripping layer online detection method, comprising the following steps:

[0069] Step one: the silicon steel to be detected enters the connecting seat 2 between the feeding seat 1 and the discharging seat 3 through the feeding seat 1, so that the silicon steel coating faces the detection assembly 4 and is in the action area of the flattening assembly 5, and the initial positioning is completed;

[0070] Step two: the motor two 6 is started, the transmission rod 59 is driven to move through the driving shaft 543 and the driving seat 542, and the two traction seats 51 are synchronously actuated;

[0071] Step three: the transmission rod 59 drives the upper seat 554 to slide, the lower seat 553 is reversely driven to slide through the rack 558 and the gear two 555, the symmetric opening and closing of the traction seat 51 are realized, and the driving strip 58 moves with the back plate 552;

[0072] Step four: the driving strip 58 meshes with the gear one 526, the driving strip 58 drives the gear one 526 to rotate to make the movable seat 523 slide, the clamping block 521 is pushed to approach the silicon steel through the connecting rod 524, and the cleaning block 527 cooperates with the spring 528 to realize the pre-clamping and foreign matter cleaning;
