Description

Technical Field

[0001] This invention relates to the field of magnetic core production, and more particularly to a laser detection device for cutting blade breakage at a winding station. Background Technology

[0002] In the automated production process of magnetic core winding, the winding station needs to precisely cut off the excess wire of the wound core. Traditional cutting devices mostly adopt a purely mechanical cutting structure with an upper cutter and a fixed lower cutter, which has many technical drawbacks in long-term, high-frequency operation. The cutter is prone to chipping, nicking, wear, or even breakage during continuous cutting operations. Existing equipment does not have online real-time detection capabilities and can only detect problems when there are broken wires, defective products, or during regular manual inspections, which can easily lead to batch defects, increasing production losses and rework costs. Summary of the Invention

[0003] The laser detection device for cutter breakage at winding stations proposed in this invention solves the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A laser detection device for detecting wire breakage at a winding station includes a winding machine. A fixed frame is fixed above the winding machine, and a mounting base is fixed above the fixed frame. The mounting base has a telescopic groove and a collection groove sequentially formed from front to back. A lower blade structure for supporting wire cutting is installed vertically within the telescopic groove of the mounting base. A cleaning structure for removing the cut wire is installed within the collection groove of the mounting base. A vertical frame is installed above the winding machine, located at the left end of the fixed frame, and a cutting structure for cutting the wire is fixed on the vertical frame. The cutting structure is located directly above the lower blade structure. A detection structure is slidably installed on the rear side of the fixed frame and connected to the cutting structure. A robotic arm for gripping the magnetic core is also installed on the front side of the winding machine. The magnetic core on the outer side of the winding on the winding machine is gripped by the robotic arm, so that the wire on the magnetic core is placed on the lower blade structure and cut by the cutting structure, thereby cutting off the excess wire.

[0005] Preferably, the cutting structure includes a cutting cylinder fixed above the upright, the push rod of the cutting cylinder passing through the upright and located below the upright, a mounting plate fixed on the push rod of the cutting cylinder, two sets of guide posts symmetrically arranged on the mounting plate about the cutting cylinder, the guide posts slidingly inserted into the upper end of the upright, and a cutting blade installed below the mounting plate. The downward extension of the push rod of the cutting cylinder can cause the cutting blade to move down, thereby cutting the wire of the magnetic core on the lower cutting structure.

[0006] Preferably, the cutting component includes a sliding column fixed to the underside of the mounting plate by a bracket. A blade holder is slidably sleeved on the sliding column, and an upper cutting blade is fixed below the blade holder by bolts. A lifting spring is sleeved on the left end of the sliding column, and the two ends of the lifting spring abut against the left end and right side bracket of the blade holder, respectively. The lifting spring causes the blade holder and the upper cutting blade to always have a tendency to move to the right. A pusher is fixed to the right end of the blade holder, and the pusher abuts against the right end bracket. The pusher abuts against the right side bracket to limit the position of the blade holder.

[0007] Preferably, the detection structure includes a lifting column fixed above the winding machine, the lifting column being located behind the fixed frame, the lifting column being slidably connected to a lifting slider, and a laser sensor being embedded in the front side of the lifting slider. The infrared laser of the laser sensor is aligned with the lower blade position of the upper cutter, and the laser sensor emits a linear laser to illuminate the blade edge of the upper cutter. The deformation of the reflected light strip is captured by a camera to reconstruct the contour of the blade. When the blade has a notch or crack, the light strip will show obvious breakage or indentation. The system can determine the location and depth of the defect by automatically comparing it with the standard contour through an algorithm. The lifting slider is fixed to the mounting plate by an L-shaped frame. The upper cutter moves up and down under the action of the cutting cylinder, which can ensure that the laser sensor can always be aligned with the cutting edge of the upper cutter and detect the cutting edge in real time. It can react quickly when the upper reflection breaks or falls off, without having to wait until it moves down to cut, thus improving detection efficiency.

[0008] Preferably, the lower blade structure includes a lower blade plate that slides vertically within a telescopic groove, with the lower blade plate directly below the upper blade. Two sets of symmetrically distributed lifting plates are fixed below the lower blade plate. Lifting grooves are provided on the lifting plates. A driving component is slidably installed between the two lifting plates. A push cylinder is mounted on the outside of the mounting base via a support, and the push rod of the push cylinder is connected to the driving component.

[0009] Preferably, the driving component includes a driving frame that is slidably inserted between two lifting plates, a driving roller that is rotatably mounted on the driving frame, a straight rod that is fixed at one end of the driving frame near the pushing cylinder, the straight rod that is slidably inserted into the mounting base, and the tail end of the straight rod that is connected to the push rod of the pushing cylinder.

[0010] Preferably, the lifting groove includes a horizontally opened holding groove, and a lifting inclined groove is opened at one end of the holding groove near the pushing cylinder, and the lifting inclined groove is designed to be inclined downward. In the initial state, that is, when the push rod of the cylinder is in the retracted state, the drive roller is at the bottom of the lifting chute, and the upper surface of the lower blade plate is flush with the upper surface of the mounting base. When the push rod of the cylinder drives the drive frame and drive roller to move to the left, the drive roller will move along the lifting chute toward the holding chute. At this time, the lifting plate and the lower cutter plate will move downward, and the lower cutter plate will move away from the upper cutter, with a certain distance between them.

[0011] Preferably, the mounting base has an extension groove, which is located at the right end of the telescopic groove. A push block is slidably installed in the extension groove, and the lower end of the push block is fixed to the straight rod. In the initial state, that is, when the push rod supplied by the cylinder is in the retracted state, due to the action of the lifting spring, the bracket at the right end of the push frame in the cutting structure abuts, the upper cutter is directly above the lower cutter plate, and the push block is at the right end of the push frame, with a certain distance between the two. The magnetic core is gripped by the robotic arm, and the wire on the magnetic core is placed on the lower blade structure. The cutting cylinder in the cutting structure causes the upper cutter to move downward and cut the wire below. At this time, the cutting edge of the upper cutter is in contact with the upper surface of the lower blade plate, and the bottom end of the pusher is below the upper surface of the pusher block. Then, when the pusher cylinder extends and drives the drive roller and the pusher to move to the left away from the pusher cylinder, the drive roller will first move a distance in the lifting chute so that the lower blade plate moves downward away from the upper cutter. When the drive roller moves into the holding groove, the side of the push block will contact the side of the push frame. Then, as the drive roller moves in the holding groove, the push block will drive the push frame and the upper cutter to shift to the left. In this way, the cutting position of the upper cutter and the wire is misaligned. Even if the cutting edge is notched, the wire will not block it, which facilitates the scanning and detection of the laser sensor and improves the detection effect.

[0012] Preferably, the telescopic groove is connected to the collection groove, and the cleaning structure includes a cleaning push plate. The upper end of the cleaning push plate has an inclined surface. When the cleaning push plate moves upward, it can lift the cut wire wheel upward, thereby lifting the part above the mounting base and letting it fall into the collection groove. The cleaning push plate has a T-shaped linear groove at the end facing the lower blade plate. A linear slider is slidably inserted in the linear groove. The linear slider is fixed in the collection groove. The cleaning push plate is slidably installed in the collection groove through the linear slider and the linear groove. The cleaning push plate has a cleaning groove. The drive roller extends into the collection groove and is slidably inserted in the cleaning groove of the cleaning push plate.

[0013] Preferably, the cleaning tank includes a horizontally designed straight groove, a downwardly inclined groove at the end of the straight groove facing the push cylinder, and an upwardly inclined groove at the end of the downward groove away from the straight groove. In the initial state, that is, when the push rod of the cylinder is in the retracted state, the drive roller is at the end of the rising groove away from the falling groove, and at this time the upper surface of the cleaning push plate is not higher than the upper surface of the mounting base. When the push rod of the cylinder drives the drive frame and drive roller to move to the left, the drive roller will first move in the rising groove, causing the cleaning push plate to move upward, thereby causing the cut wire wheel to be lifted upward, thus lifting the part above the mounting seat and letting it fall into the collection groove, preventing the cut wire from obstructing the cutting edge of the upper cutter. Then the drive roller continues to move to the left and in the falling groove, at which time the cleaning push plate moves downward. When the drive roller is at the intersection of the descending groove and the straight groove, the upper surface of the cleaning push plate is below the upper surface of the mounting base and will not obstruct the upper cutter. At this time, the drive roller is in the lifting inclined groove of the lifting plate and has not yet moved into the holding groove.

[0014] The beneficial effects of this invention are: 1. This device uses a laser sensor to synchronously lift and move the upper cutter, enabling online, non-contact, real-time detection of the cutter's edge status. It can quickly identify defects such as chipping, breakage, and wear of the cutting edge without requiring machine downtime for inspection, effectively avoiding the generation of batches of defective products and significantly improving production stability and product qualification rate.

[0015] 2. By adopting an integrated linkage structure driven by a single power source, the cut wire waste is first pushed into the collection tank by the cleaning push plate to complete the automatic cleaning, then the lower blade plate is driven to descend and avoid it, and finally the upper cutter is pushed to shift horizontally. The whole process is unobstructed and interference-free, allowing the laser sensor to completely capture the blade edge contour, which significantly improves the detection accuracy and reliability, and fundamentally solves the detection failure problem caused by waste and structural obstruction.

[0016] 3. By designing the sequence of the lower blade plate descending first and the upper blade shifting later, mechanical scraping and wear between the cutter and the lower blade plate can be completely avoided. Combined with smooth linkage action, it effectively reduces mechanical impact and wear, and extends the service life of the cutter and the whole machine. At the same time, the cleaning push plate automatically completes the lifting and collection of waste materials with the cooperation of the drive roller and the cleaning tank, eliminating the need for manual cleaning, keeping the working surface clean, and ensuring the continuous and stable operation of the cutting and inspection process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1 - Figure 8A laser detection device for wire cutting breakage at a winding station includes a winding machine base 1, a fixed frame 2 above the winding machine base 1, and a mounting base 3 above the fixed frame 2. The mounting base 3 has a telescopic groove 31 and a collection groove 32 arranged sequentially from front to back. A lowering structure 6 for supporting wire cutting is installed vertically within the telescopic groove 31 on the mounting base 3. A cleaning structure 7 for removing the cut wire is installed within the collection groove 32 on the mounting base 3. A vertical frame 41 is installed above the winding machine base 1. At the left end of the fixed frame 2, and on the upright frame 41, there is a cutting structure 4 for cutting the wire. The cutting structure 4 is located directly above the lower blade structure 6. A detection structure 5 is slidably installed on the rear side of the fixed frame 2. The detection structure 5 is connected to the cutting structure 4. A robotic arm for gripping the magnetic core 8 is also installed on the front side of the winding machine table 1. The magnetic core 8 on the outer side of the winding on the winding machine table 1 is gripped by the robotic arm, so that the wire on the magnetic core 8 is placed on the lower blade structure 6 and cut by the cutting structure 4, thereby cutting off the excess wire.

[0021] Reference Figure 3 , Figure 4 The cutting structure 4 includes a cutting cylinder 42 fixed above the support frame 41. The push rod of the cutting cylinder 42 passes through the support frame 41 and is located below the support frame 41. A mounting plate 43 is fixed on the push rod of the cutting cylinder 42. Two sets of guide columns 431 are symmetrically arranged on the mounting plate 43 about the cutting cylinder 42. The guide columns 431 are slidably inserted into the upper end of the support frame 41. A cutting blade 44 is installed below the mounting plate 43. The downward extension of the push rod of the cutting cylinder 42 can cause the cutting blade 44 to move down, thereby cutting the wire of the magnetic core 8 on the lower cutting structure 6.

[0022] Reference Figure 4 The cutting component 44 includes a sliding column 441 fixed to the underside of the mounting plate 43 via a bracket 432. A blade holder 442 is slidably sleeved on the sliding column 441. An upper cutting blade 444 is fixed below the blade holder 442 by bolts. A lifting spring 443 is sleeved on the left end of the sliding column 441. The two ends of the lifting spring 443 abut against the left end and the right side bracket 432 of the blade holder 442, respectively. The lifting spring 443 causes the blade holder 442 and the upper cutting blade 444 to always have a tendency to move to the right. A pusher 445 is fixed to the right end of the blade holder 442. The pusher 445 abuts against the right end bracket 432 and the right side bracket 432 to limit the position of the blade holder 442.

[0023] Reference Figure 4The detection structure 5 includes a lifting column 51 fixed above the winding machine 1. The lifting column 51 is located behind the fixed frame 2. A lifting slider 52 is slidably connected to the lifting column 51. A laser sensor 53 is embedded in the front of the lifting slider 52. The infrared laser of the laser sensor 53 is aligned with the lower blade position of the upper cutter 444. The laser sensor 53 emits a linear laser beam to illuminate the blade edge of the upper cutter 444. The laser sensor 53 is a 3D laser scanning sensor, which can capture the deformation of the reflected light strip through a camera and reconstruct the image. When the blade has a notch or crack, the light strip will show obvious breakage or indentation. The system can automatically determine the location and depth of the defect by comparing it with the standard contour through an algorithm. The lifting slider 52 is fixed to the mounting plate 43 by the L-shaped frame. The upper cutter 444 moves up and down under the action of the cutting cylinder 42, which can ensure that the laser sensor 53 can always be aligned with the cutting edge of the upper cutter 444 and detect its cutting edge in real time. It can react quickly when the upper reflection breaks or falls off, without having to wait for the lower cutting to detect, thus improving the detection efficiency.

[0024] Reference Figure 5 - Figure 7 The lower blade structure 6 includes a lower blade plate 61 that slides up and down in the telescopic groove 31. The lower blade plate 61 is directly below the upper cutter 444. Two sets of symmetrically distributed lifting plates 65 are fixed below the lower blade plate 61. Lifting grooves 66 are provided on the lifting plates 65. A drive component 64 is slidably installed between the two lifting plates 65. A push cylinder 63 is installed on the outside of the mounting base 3 through a support. The push rod of the push cylinder 63 is connected to the drive component 64.

[0025] Reference Figure 7 The driving component 64 includes a driving frame 641 that is slidably inserted between two lifting plates 65. A driving roller 642 is rotatably mounted on the driving frame 641. A straight rod is fixed at one end of the driving frame 641 near the pushing cylinder 63. The straight rod is slidably inserted into the mounting base 3, and the tail end of the straight rod is connected to the push rod of the pushing cylinder 63.

[0026] Reference Figure 6 , Figure 7 The lifting groove 66 includes a horizontally opened holding groove 661, and a lifting inclined groove 662 is opened at one end of the holding groove 661 near the pushing cylinder 63. The lifting inclined groove 662 is designed to be inclined downward. In the initial state, that is, when the push rod of the cylinder 63 is in the retracted state, the drive roller 642 is at the lowest end of the lifting chute 662, and at this time the upper surface of the lower blade plate 61 is flush with the upper surface of the mounting base 3. When the push rod of the cylinder 63 drives the drive frame 641 and drive roller 642 to move to the left, the drive roller 642 will move along the lifting sloping groove 662 toward the holding groove 661. At this time, the lifting plate 65 and the lower blade plate 61 will move downward, and the lower blade plate 61 will move away from the upper cutter 444, with a certain distance between them. Then the push rod of the cylinder 63 drives the drive frame 641 and drive roller 642 to continue to move to the left. The drive roller 642 moves in the holding groove 661, while the position of the lower blade 61 remains unchanged. Conversely, when the push rod of the push cylinder 63 drives the drive roller 642 to move to the right, the position of the lower blade plate 61 remains unchanged in the holding groove 661. Then, when it moves to the right in the lifting sloping groove 662 and approaches the push cylinder 63, the position of the lower blade plate 61 rises until it returns to the initial position.

[0027] Reference Figure 5 - Figure 7 An extension groove 33 is provided on the mounting base 3. The extension groove 33 is located at the right end of the telescopic groove 31. A push block 62 is slidably installed in the extension groove 33. The lower end of the push block 62 is fixed to the straight rod. In the initial state, that is, when the push rod given by the cylinder 63 is in the retracted state, due to the action of the lifting spring 443, the bracket 432 at the right end of the push frame 445 in the cutting structure 4 abuts, the upper cutter 444 is directly above the lower cutter plate 61, and the push block 62 is at the right end of the push frame 445, with a certain distance between the two. Under the action of the robotic arm, the wire on the magnetic core 8 is grasped and placed on the lower blade structure 6. Then, the cutting cylinder 42 in the cutting structure 4 causes the upper cutter 444 to move downward and cut the wire below. At this time, the cutting edge of the upper cutter 444 is in contact with the upper surface of the lower blade plate 61, and the bottom end of the pusher 445 is below the upper surface of the pusher block 62. Then, when the push rod of the pusher cylinder 63 extends and drives the drive roller 642 and the pusher 445 to move to the left away from the pusher cylinder 63, the drive roller 642 will first move a distance in the lifting chute 662 so that the lower blade plate 61 moves downward away from the upper cutter 444. There is a certain gap between the lower blade plate 61 and the upper cutter 444. When the upper cutter 444 moves laterally, there will be no friction between the two, thus avoiding wear of the upper cutter 444. When the drive roller 642 moves into the holding groove 661, the side of the push block 62 will contact the side of the push frame 445. Then, as the drive roller 642 moves in the holding groove 661, the push block 62 will drive the push frame 445 and the upper cutter 444 to shift to the left. In this way, the cutting position of the upper cutter 444 and the wire is misaligned. Even if the cutting edge is notched, the wire will not block it, which facilitates the scanning and detection of the laser sensor 53 and improves the detection effect. The linkage design between the lower blade 61 and the upper cutter 444 ensures that the upper cutter 444 can only shift after the lower blade 61 moves downward a certain distance. This prevents wear between the two blades during the shift. Furthermore, when the lower blade 61 moves downward, if the upper cutter 444 creates a notch but fails to cut the wire, the wire will bend to a certain extent due to the shift of the upper cutter 444, making it easier to expose the notch and improving the accuracy of the detection.

[0028] Reference Figure 5 - Figure 7 The telescopic groove 31 is connected to the collection groove 32. The cleaning structure 7 includes a cleaning push plate 71. The upper end of the cleaning push plate 71 is provided with an inclined surface. When the cleaning push plate 71 moves upward, it can lift the cut wire wheel upward, thereby lifting the part above the mounting base 3 and letting it fall into the collection groove 32. The cleaning push plate 71 has a T-shaped straight slide groove 73 at the end facing the lower blade plate 61. A straight slider 74 is slidably inserted in the straight slide groove 73. The straight slider 74 is fixed in the collection groove 32. The cleaning push plate 71 is slidably installed in the collection groove 32 through the straight slider 74 and the straight slide groove 73. The cleaning push plate 71 has a cleaning groove 72. The drive roller 642 extends into the collection groove 32 and is slidably inserted into the cleaning groove 72 of the cleaning push plate 71.

[0029] Reference Figure 6 , Figure 7 The cleaning tank 72 includes a horizontally designed straight groove 723, a downwardly inclined groove 722 at one end of the straight groove 723 facing the push cylinder 63, and an upwardly inclined groove 721 at the other end of the downward groove 722 away from the straight groove 723. In the initial state, that is, when the push rod of the cylinder 63 is in the retracted state, the drive roller 642 is at the end of the rising groove 721 away from the falling groove 722, and at this time the upper surface of the cleaning push plate 71 is not higher than the upper surface of the mounting base 3. When the push rod of the cylinder 63 drives the drive frame 641 and drive roller 642 to move to the left, the drive roller 642 will first move in the rising groove 721, causing the cleaning push plate 71 to move upward, thereby causing the cut wire to be lifted upward, thus lifting the part above the mounting base 3 and letting it fall into the collection groove 32, so as to avoid the cut wire from blocking the cutting edge of the upper cutter 444. Then the drive roller 642 continues to move to the left and in the falling groove 722, at which time the cleaning push plate 71 moves downward. When the drive roller 642 is at the intersection of the descending groove 722 and the straight groove 723, the upper surface of the cleaning push plate 71 is below the upper surface of the mounting base 3 and will not obstruct the upper cutter 444. At this time, the drive roller 642 is in the lifting inclined groove 662 of the lifting plate 65 and has not yet moved into the holding groove 661. Then the drive roller 642 continues to move to the left. The drive roller 642 moves in the straight groove 723, and the height of the cleaning push plate 71 remains unchanged. At this time, the drive roller 642 moves in the lifting inclined groove 662 and the holding groove 661, causing the lower blade plate 61 to move down. The cleaning push plate 71 is designed to be linked with the cleaning groove 72, the drive roller 642, the lower blade plate 61, and the upper cutter 444. After the cleaning push plate 71 is lifted, cleaned, and reset, the upper cutter 444 can be offset to avoid obstructing it and affecting subsequent inspections.

[0030] Working principle: In the initial state, the push rod of the cylinder 63 is in the retracted state, the drive roller 642 of the drive component 64 is located at the lowest end of the lifting groove 662 of the lifting groove 66 of the lifting plate 65, the upper surface of the lower blade plate 61 of the lower blade structure 6 is flush with the upper surface of the mounting base 3, and at the same time, the drive roller 642 is at the end of the rising groove 721 of the cleaning groove 72 on the cleaning push plate 71. The upper surface of the cleaning push plate 71 is not higher than the upper surface of the mounting base 3. The lifting spring 443 of the cutter component 44 pushes the blade holder 442 and the upper cutter 444 to maintain a rightward trend. The push frame 445 abuts against the right support 432 for limit positioning. The upper cutter 444 is precisely positioned above the lower blade plate 61. The push block 62 and the push frame 445 maintain a distance. The laser sensor 53 of the detection structure 5 is positioned with the lifting slider 52, and its laser beam is aligned with the cutting edge of the upper cutter 444.

[0031] When the winding operation is completed and cutting is required, the robotic arm on the front side of the winding machine 1 grabs the magnetic core 8 and places the wire to be cut on the magnetic core 8 onto the lower blade plate 61. Then the cutting structure 4 is activated, and the cutting cylinder 42 on the upright 41 extends downward, driving the mounting plate 43 and guide column 431 to move smoothly down along the upright 41, thereby driving the cutter 44 to descend as a whole. The upper cutter 444 and the lower blade plate 61 cooperate to complete the wire cutting. At this time, the cutting edge of the upper cutter 444 contacts the surface of the lower blade plate 61, and the bottom end of the pusher 445 moves to below the upper surface of the pusher block 62.

[0032] After the wire is cut, the push rod of the cylinder 63 begins to extend, driving the drive frame 641 and drive roller 642 to move to the left. The drive roller 642 first slides in the rising groove 721 of the cleaning tank 72, driving the cleaning push plate 71 to rise along the linear slider 74 and the linear slide groove 73, lifting the cut wire waste and pushing it into the collection groove 32 of the mounting base 3, preventing the waste from blocking the cutting edge of the upper cutter 444. Then the drive roller 642 enters the descending groove 722, and the cleaning push plate 71 returns to its original position, its surface falling below the upper surface of the mounting base 3, reserving space for subsequent cutter detection. During this process, the lower cutter plate 61 is always in a state of moving downward away from the upper cutter 444, so as to ensure that when the upper cutter 444 is deflected later, no wear will occur between the lower cutter plate 61 and the upper cutter 444, until the drive roller 642 moves into the holding groove 661 and the linear groove 723. After the drive roller 642 enters the holding groove 661, the drive roller 642 continues to move to the left away from the push cylinder 63. During this process, the height of the lower blade plate 61 and the cleaning push plate 71 remains unchanged. At the same time, the push block 62, which is fixed to the straight rod, moves to the left with the straight rod, and its side contacts the side of the push frame 445. This pushes the push frame 445, the blade holder 442 and the upper cutter 444 to the left along the sliding column 441, so that the cutting edge of the upper cutter 444 is fully exposed, avoiding the wire and the cutting structure 4 from being blocked.

[0033] In actual cutting operations, if the cutting edge of the upper cutting blade 444 chipped or broke due to high-frequency cutting, the detection method of the upper cutting blade 444 resetting upward with the cutting cylinder 42 and the laser sensor 53 moving upward synchronously cannot fully expose the cutting edge defect, and it is very easy to miss the detection. Specifically, there are the following two situations: 1. The cutting edge has a local chipping but can still cut the wire. At this time, the cut wire is still attached to the surface of the cutting edge or embedded in the chipping position. When the upper cutting blade 444 is below, the laser sensor 5 does not detect the existence of the chipping in time, the optical sensor 53 cannot identify the chipping, the system misjudges the cutting blade to be normal, and the robot directly grabs the unqualified magnetic core 8 and places it in the qualified position, causing the unqualified magnetic core 8 to flow into the next process. 2. Severe chipping of the cutting edge prevents the wire from being completely cut. The uncut wire gets stuck in the notch of the cutting edge and tightly wraps around the defect. At this time, whether the upper cutter 444 is in the cutting position or the rising reset position, the wire will completely block the notch. The laser sensor 53 cannot detect the abnormal cutting edge contour. After the upper cutter 444 is reset, the robot will still grab the magnetic core 8 with the uncut wire as a qualified product, directly producing a defective product that is unqualified in both appearance and function.

[0034] After the upper cutter 444 cuts the wire by moving down, the lower cutter structure 6 causes the lower cutter plate 61 to move down to avoid the upper cutter 444. Then, the upper cutter 444 is offset in position, exposing the cutting position of the upper cutter 444. This avoids the wire from blocking the wire and causing errors in detection and judgment, and can effectively prevent unqualified products from flowing out.

[0035] The detection structure 5 moves synchronously with the cutting structure 4. The lifting slider 52 is fixed to the mounting plate 43 by the L-shaped frame, ensuring that the laser sensor 53 always moves up and down with the upper cutter 444 and is aligned with the cutting edge in real time. The laser sensor 53 emits a line laser to irradiate the cutting edge. By capturing the deformation of the reflected light strip, the blade contour is reconstructed. When the cutting edge has a notch, crack, or break, the light strip will show obvious breakage or indentation, realizing real-time, non-contact detection of cutter breakage.

[0036] After the test is completed, the cylinder 63 push rod retracts and resets, the drive roller 642 moves back to the right, and moves sequentially in the holding groove 661 and the lifting inclined groove 662, driving the lower blade plate 61 to rise and reset to the initial height; at the same time, the push block 62 moves to the right to release the thrust on the push frame 445, the lifting spring 443 pushes the blade holder 442 and the upper cutter 444 to move to the right and reset, and the drive roller 642 finally returns to the initial position of the rising groove 721 of the cleaning groove 72. The cleaning push plate 71, the lower blade plate 61 and the upper cutter 444 all return to their initial state, and the device enters the next cutting and testing cycle, realizing the automated linkage operation of wire cutting, waste cleaning and cutter breakage detection throughout the process.
