DETAILED DESCRIPTION

[0046] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0048] Grain-oriented silicon steel (GOSI) is a type of electrical steel and a key material for power equipment. Also known as cold-rolled transformer silicon steel, GOSI is a special ferrosilicon alloy specifically used in the cores of power equipment such as transformers and large motors. The iron loss (hysteresis loss and eddy current loss) of GOSI directly impacts the energy efficiency of power equipment such as transformers. Creating notches on the surface of GOSI can reduce this iron loss.

[0049] Laser scoring technology uses a laser beam to scan the surface of oriented silicon steel at high speed, creating fine scoring lines. Laser scoring can improve the performance of oriented silicon steel and is the most direct and effective means of reducing steel loss in oriented silicon steel.

[0050] Laser scoring is typically performed using scoring equipment. When scoring oriented silicon steel, the steel is placed horizontally and a laser beam directed perpendicular to the surface is used to ablate the steel, creating a score on the surface. While this method can achieve scoring of oriented silicon steel to a certain extent, the scoring type is limited, and multiple scoring types (e.g., heat-resistant scoring, non-heat-resistant scoring with visible score lines, and non-heat-resistant scoring with invisible score lines) cannot be achieved simultaneously. Furthermore, the scoring effect is unsatisfactory.

[0051] In view of this, the present application provides an electrical steel sheet scoring device. The electrical steel sheet scoring device of an embodiment of the present application is introduced below.

[0052] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic structural diagram of an electrical steel sheet scoring device according to some embodiments of the present application; Figure 2 This is a schematic diagram of the connection between the scanning component, the column and the supporting platform in some embodiments of the present application.

[0053] An embodiment of the present application provides an electrical steel sheet scoring device, comprising a workbench, a lifting assembly, a laser assembly, and a purge assembly. Among them, the workbench includes a support member 1, a bearing platform 2 and a driving member 3. The transfer side of the bearing platform 2 is rotatably connected to the support member 1. The driving member 3 is respectively connected to the support member 1 and the bearing platform 2, and is used to drive the bearing platform 2 to rotate around the transfer side; the lifting component includes a column 7, a driving mechanism and an adjusting seat 8. The column is arranged on the bearing platform 2, the driving mechanism is arranged on the column 7, and the adjusting seat 8 is arranged on the driving mechanism, and is used to rise and fall relative to the bearing platform 2 under the drive of the driving mechanism; the laser component includes a laser, a scanning component 4 and a control card. The laser is arranged on the support member 1 for generating laser, and the scanning component 4 is arranged on the adjusting seat 8 for emitting laser to the bearing platform 2 to inscribe the electrical steel sheet. The control card is respectively connected to the laser and the scanning component 4 for controlling the laser parameters; the blowing component includes an air supply member and a wind knife module 5. The air supply member is connected to the wind knife module 5 for supplying air. The wind knife module 5 is arranged on the installation side of the bearing platform 2, and is used to blow air from the installation side to the transfer side to form a protective atmosphere and / or clean the slag.

[0054] In the workbench, both the carrier platform 2 and the driver 3 are mounted on the support 1. The carrier platform 2 has a transfer side and a mounting side. The transfer side is rotatably connected to the support 1, and the purge assembly is mounted on the mounting side. The area between the transfer side and the mounting side of the carrier platform 2 can support electrical steel sheets, providing a placement for the sheets. The driver 3 is connected to the carrier platform 2 and provides driving power to rotate the carrier platform 2 around the transfer side on the support 1.

[0055] When the driving member 3 drives the supporting platform 2 to rotate, various implementations are possible. For example, the driving member 3 can be a motor, rotary cylinder, hydraulic motor, or other element that provides rotational power, which can drive the supporting platform 2 to rotate during rotation. The driving member 3 can also be an electric push rod, air cylinder, hydraulic cylinder, or other element that provides linear power, which can drive the supporting platform 2 to rotate during extension and retraction. The driving member 3 can also be a combination of a motor and a transmission mechanism, which can be a flexible transmission mechanism such as a chain transmission mechanism or a belt transmission mechanism.

[0056] The column 7 is arranged on the supporting platform 2, the driving mechanism is arranged on the column 7, the adjustment seat 8 is arranged on the driving mechanism, and the scanning component 4 is arranged on the adjustment seat 8. Under the drive of the driving mechanism, the adjustment seat 8 can drive the scanning component 4 to move to change the spot size of the laser projected on the electrical steel sheet.

[0057] In the laser assembly, the laser is connected to the scanning assembly 4, and the laser emitted by the laser can be directed to the electrical steel sheet through the scanning assembly 4, thereby marking the electrical steel sheet. The control card is respectively connected to the laser scanning assembly 4 and can provide control for the operation of the laser assembly. The adjustment seat 8 drives the scanning assembly 4 to rise and fall relative to the carrier 2, changes the distance from the electrical steel sheet, and cooperates with the control card to adjust the parameters of the laser, which can form non-heat-resistant marks with visible marking lines, non-heat-resistant marks with invisible marking lines, and heat-resistant marks with adjustable groove depth on the electrical steel sheet (the groove depth range can be 0μm to 35μm). In addition, multiple scans can be performed to repeat the marking (the repetition accuracy is ±3μm), and the angle between the marking line and the rolling direction can be adjusted (the adjustment range is 0° to 90°).

[0058] In the purge assembly, the air supply component can be installed on the support member 1 or not (for example, the air supply component can be installed inside or outside the laboratory). The air supply component can provide compressed gas to the air knife module 5, so that the air knife module 5 blows air onto the carrier 2, so that the electrical steel sheet is scored in the blowing environment. When the air supply component provides compressed gas, it is preferably an inert gas, such as nitrogen, which can form a protective atmosphere. Of course, the air supply component can also choose compressed air.

[0059] In the technical solution of the above embodiment, the carrier 2 can be used to place electrical steel sheets, and the scanning component 4 can emit a laser onto the electrical steel sheets, thereby achieving scoring of the electrical steel sheets. The drive mechanism can drive the adjustment seat 8 up and down, so that the scanning component 4 approaches or moves away from the carrier 2, thereby adjusting the laser spot size during scoring, flexibly adjusting the scoring width and depth, and achieving the processing of heat-resistant scoring and non-heat-resistant scoring (with visible or invisible scoring lines), so that the electrical steel sheet scoring device can integrate multiple scoring methods. In addition, the drive member 3 can drive the carrier 2 to rotate on the support member 1, so that the carrier 2 can be tilted at different angles to the horizontal plane. The air knife module 5 can blow air from top to bottom along the tilt direction of the carrier 2 to form a protective atmosphere, so that the slag formed by the scoring can fall along the tilt direction of the carrier 2 under the combined action of its own gravity and wind force, avoiding the accumulation and splashing of slag at the scoring position and improving the scoring quality.

[0060] like Figure 1 As shown, in some embodiments, one end of the driving member 3 is rotatably connected to the support member 1, and the other end is rotatably connected to the supporting platform 2, for providing a linear driving force to push and pull the supporting platform 2 to rotate.

[0061] The adapter side of the support platform 2 is rotatably connected to the support member 1, and the driver 3 is rotatably connected to the support member 1 and the support platform 2. When achieving this rotatable connection, the rotatable connection can be achieved through bearings or a hinged connection. Preferably, the adapter side is hingedly connected to the support member 1, and the driver 3 is hingedly connected to the support platform 2 and the support member 1, respectively. This structure is simple and easy to implement. The driver 3 is preferably a servo electric cylinder, which can improve the motion accuracy of the support platform 2 when driving the rotation of the support platform 2.

[0062] In the technical solution of the above embodiment, the driving member 3 can provide a linear driving force, driving the supporting platform 2 to rotate in the form of pushing and pulling. Compared with using rotational power to control the supporting platform 2, it can improve the stability of the supporting platform 2 and reduce the load.

[0063] like Figure 1 As shown, in some embodiments, the connection position between the driving member 3 and the supporting platform 2 is located between the transfer side and the installation side.

[0064] The driving member 3 is hingedly connected to the supporting platform 2, and its connection position can be close to the transfer side, close to the installation side, or at an equal distance from the transfer side and the installation side. When the connection position is close to the installation side, the load of the driving member 3 is small, but the expansion and contraction amount is large; when the connection position is close to the transfer side, the expansion and contraction amount of the driving member 3 is small, but the load is large. The transfer side of the supporting platform 2 is rotatably connected to the support member 1 through a hinged connection. On the support member 1, a support foot can be set at a position corresponding to the installation side of the supporting platform 2, and the support foot can abut the supporting platform 2 to provide support for the supporting platform 2.

[0065] In the technical solution of the above embodiment, the driving member 3 provides driving force to the supporting platform 2 through the connection position with the supporting platform 2. The position for providing driving force (that is, the connection position) is located between the transfer side and the installation side, which can coordinate the extension and contraction amount and load of the driving member 3 so that both are within a better range.

[0066] Please refer to Figure 3 , Figure 3 For this application Figure 2 Enlarged schematic diagram at I.

[0067] In some embodiments, the wind knife module 5 includes a support 51, a mounting frame 52 and a wind knife 53. The support 51 is arranged on the installation side, the mounting frame 52 is arranged on the support 51, and the wind knife 53 is arranged on the mounting frame 52. The mounting frame 52 is movably connected to the support 51 for adjusting the angle and / or height of the wind knife 53.

[0068] The support 51 is installed on the top surface of the installation side, and the mounting frame 52 can be rotatably connected to the support 51, or can be movably connected to the support 51, or can be both rotatably connected to the support 51 and movably connected to the support 51. When the mounting frame 52 is rotatably connected to the support 51 (for example, a sliding fit), the installation angle of the wind knife 53 can be adjusted, thereby adjusting the blowing angle; when the mounting frame 52 is movably connected to the support 51, the distance between the wind knife 53 and the support platform 2 can be adjusted, thereby adjusting the blowing height on the support platform 2. On the mounting frame 52, the number of wind knives 53 can be one or more. Preferably, there are multiple wind knives 53, and they are respectively connected to the air supply parts. Each wind knife 53 can blow air independently, thereby improving the flexibility of blowing.

[0069] In the technical solution of the above embodiment, the mounting frame 52 is movably connected to the support 51. By adjusting the mounting frame 52, the blowing angle and blowing height of the wind knife 53 can be adjusted, and the blowing angle and height can be adjusted simultaneously, so that the atmosphere environment of laser scoring can be flexibly adjusted.

[0070] like Figure 3 As shown, in some embodiments, an adjustment groove 511 is provided on the support 51, and the extension direction of the adjustment groove 511 is perpendicular to the supporting platform 2. A fastener is provided on the mounting frame 52, and the fastener is threadedly connected to the end of the mounting frame 52, and is inserted into the adjustment groove 511 and abuts against the support 51 to adjust the angle and height of the wind knife 53.

[0071] Exemplarily, there are two supports 51, one located on either side of the mounting bracket 52 in its longitudinal direction. The adjustment slot 511 is a through-slot in the support 51, and the fastener is a hexagon socket head bolt. The width of the adjustment slot 511 is greater than the nominal diameter of the bolt and less than the head diameter of the bolt. The fastener is threadedly connected to the mounting bracket 52 and abuts against the support 51, thereby securing the mounting bracket 52 to the support 51.

[0072] When adjusting the angle and height of the wind knife 53 , first loosen the fasteners so that the mounting frame 52 can move freely (rotate and translate). After adjusting the mounting frame 52 , tighten the fasteners to fix the mounting frame 52 on the support 51 .

[0073] In the technical solution of the above embodiment, the mounting frame 52 can be flexibly installed on the support 51 through the adjustment groove 511 on the support 51 and the fasteners on the mounting frame 52, so that the angle and height of the wind knife 53 can be flexibly adjusted, which is convenient for adjusting the blowing angle and height.

[0074] Please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic structural diagram of the gas collecting member in some embodiments of the present application at a viewing angle; Figure 6 This is a schematic structural diagram of the gas collecting component in some embodiments of the present application from another perspective.

[0075] In some embodiments, the electrical steel sheet scoring device also includes a flue gas purification component, which includes a purification body and a gas collecting part 6. The purification body is arranged on the support 1 and is used to purify the flue gas. The gas collecting part 6 is arranged on the transfer side and is connected to the purification body for collecting the flue gas blown by the purge component.

[0076] For example, the purification system may include a purification rack, a processing unit mounted within the rack, and a fan. The purification rack forms a purification chamber and is connected to the air collection unit 6 via a pipe. When purifying the flue gas, the fan operates, extracting air from the air collection unit 6. The extracted flue gas passes through the processing unit and the fan before being discharged. The processing unit may include one or more HEPA modules (High-Efficiency Particulate Air).

[0077] In the technical solution of the above-mentioned embodiment, the gas collection member 6 of the flue gas purification assembly is arranged on the adapter side, and correspondingly, the air knife module 5 of the purge assembly is arranged on the installation side. The gas blown by the purge assembly passes through the electrical steel sheet and is collected by the gas collection member 6. It is then processed by the purification body, which can treat the flue gas generated during laser scoring, thereby reducing its impact on the human body. In addition, the gas collection member 6 is located downstream of the gas flow, which can not only passively collect gas, but also actively collect gas under the action of the purification body, thereby improving the efficiency of flue gas treatment.

[0078] like Figure 5 and Figure 6 As shown, in some embodiments, the air collecting part 6 includes a first-level air collecting hood 61 and a second-level air collecting hood 62. The first-level air collecting hood 61 is arranged on the adapter side, and the opening faces the wind knife module 5. The side facing the opening is provided with a vent 611. The second-level air collecting hood 62 is arranged on the first-level air collecting hood 61, and the opening covers the vent 611 to form an air chamber. The second-level air collecting hood 62 is provided with a transmission port 621 facing the vent 611, which is used to purify the main body to extract the flue gas through the first-level air collecting hood 61 and the second-level air collecting hood 62 in sequence.

[0079] When the gas passes through the gas collecting member 6, it enters the first-stage gas collecting hood 61 through the opening of the first-stage gas collecting hood 61, then enters the gas warehouse through the vent 611, and finally enters the purification body through the pipeline through the transmission port 621 to be purified.

[0080] In the technical solution of the above embodiment, the first-stage gas collecting hood 61 is open on one side and can collect smoke. The first-stage gas collecting hood 61 and the second-stage gas collecting hood 62 form an air chamber, which can effectively suppress the overflow of smoke, thereby maintaining the stability of the airflow.

[0081] Preferably, there are multiple vents 611 arranged at intervals along the length direction of the first-stage air collecting hood 61. The vents 611 are rectangular and their length direction is consistent with that of the first-stage air collecting hood 61, which can increase the air intake volume.

[0082] Preferably, the transmission port 621 is one and circular, projected from the first-level gas collecting hood 61 to the second-level gas collecting hood 62, and the outer contour of the vent 611 is spaced apart from the outer contour of the transmission port 621, which can further suppress the overflow of smoke in the gas bin and provide a smooth airflow environment for laser marking.

[0083] Please refer to Figure 7 , Figure 7 Schematic diagram of the disassembly of the electromagnetic carrier according to some embodiments of the present application.

[0084] In some embodiments, the supporting platform 2 includes a base plate 21 and an electromagnetic carrier 22 . The base plate 21 is connected to the support member 1 and the driving member 3 respectively. The electromagnetic carrier 22 is arranged on the base plate 21 to provide electromagnetic attraction to fix the electrical steel sheet.

[0085] For example, the base plate 21 is hingedly connected to the support member 1 and the driving member 3. The electromagnetic carrier 22 is provided on the top surface of the base plate 21. When powered on, the electromagnetic carrier 22 can generate a magnetic force, thereby adsorbing the electrical steel sheet on the electromagnetic carrier 22 to fix the electrical steel sheet. When the electromagnetic carrier 22 is powered off, the magnetic force disappears.

[0086] In the technical solution of the above embodiment, the electromagnetic carrier 22 provides a placement for the electrical steel sheet and secures the sheet, preventing it from shifting during scoring. Furthermore, magnetically securing the sheet ensures that it remains flat on the electromagnetic carrier 22, thereby improving scoring accuracy.

[0087] Preferably, the electromagnetic carrier 22 includes a separator layer 221, a sandwich layer 222, and a panel layer 223. The separator layer 221 is disposed on the substrate 21. The separator layer 221 may be made of an insulating material and provides a mounting location for the sandwich layer 222 and the panel layer 223. The sandwich layer 222 is disposed on the separator layer 221 and includes a wiring groove and a plurality of electromagnets arranged in series within the wiring groove. The wiring groove of the sandwich layer 222 provides mounting space for the electromagnets, which can generate magnetic force when energized. The panel layer 223 is arranged on the plywood layer 222. The panel layer 223 includes a positioning block and a plurality of through holes. The through holes are connected to the electromagnets in a one-to-one correspondence, so that there is no obstruction between the electromagnets and the electrical steel sheets, which can improve the suction force of the electromagnets on the electrical steel sheets; the positioning block is used to provide positioning for the electrical steel sheets. When the electrical steel sheets are placed on the electromagnetic carrier 22, they can rely on the positioning block for positioning. By setting the positioning block and the electromagnet, the scoring deviation can be made less than 0.05mm when the electrical steel sheets are scored on both sides, thereby improving the scoring accuracy.

[0088] The panel layer 223 can have multiple positioning blocks, enabling positioning of electrical steel sheets of varying specifications, useful for laboratory laser scoring research on electrical steel sheets. For example, the positioning blocks can position three sizes of electrical steel sheets: 30mm x 300mm, 100mm x 500mm, and 500mm x 500mm. The thickness ranges from 0.15mm to 0.35mm, and the material is silicon steel. This provides a reference for laser scoring research on electrical steel sheets, shortening the development cycle.

[0089] Please refer to Figure 8 , Figure 8 This is a schematic structural diagram of the scanning component of some embodiments of the present application.

[0090] In some embodiments, the scanning assembly 4 includes a protective member 41, a scanning head 42, a focusing module 43, a steering member 44, a collimating member 45 and a connecting member 46. The scanning head 42 and the focusing module 43 are both arranged in the protective member 41. The steering member 44 is arranged at one end of the protective member 41. The collimating member 45 is connected to the steering member 44. The connecting member 46 is respectively connected to the collimating member 45 and the laser. The connecting member 46, the collimating member 45, the steering member 44, the focusing module 43 and the scanning head 42 pass through the laser in the direction of laser propagation in sequence.

[0091] The scanning head 42, adjustment module, and steering member 44 are all mounted on the enclosure 41. The scanning head 42 can emit laser light toward the electrical steel sheet and adjust the laser emission angle. The focusing module 43 can adjust the focusing parameters of the laser to change the thickness of the laser.

[0092] For example, a laser galvanometer may be provided in the scanning head 42 , and when the scanning head 42 receives the laser, the laser galvanometer can adjust the direction of the laser.

[0093] Exemplarily, the focusing module 43 may include a plurality of focusing lenses, such as two focusing lenses, which can adjust the divergence angle of the laser, thereby changing the thickness of the laser.

[0094] For example, the steering member 44 is a reflector with a 45° angle to the incident laser for laser steering, the collimating member 45 is a collimating mirror, the laser is a fiber laser, and the connecting member 46 is an optical fiber with an optical fiber connector.

[0095] The laser light emitted by the fiber laser is transmitted to the fiber connector through the optical fiber, and then transmitted to the collimator lens by the fiber connector. After being collimated, it is transmitted to the steering member 44. After the propagation direction is changed by 90° at the steering member 44, it is transmitted to the focusing module 43. Under the control of the control card, the focusing module 43 can adjust the divergence angle of the laser and change the thickness (focus) of the laser. Then, the laser light passes through the scanning head 42 and is shot onto the electrical steel sheet, thereby making a mark on the electrical steel sheet.

[0096] By adjusting the laser parameters through the fiber laser and the scanning component 4, non-heat-resistant scoring and heat-resistant scoring of the electrical steel sheet can be achieved. Among them, non-heat-resistant scoring refers to scoring that disappears after heating, and heat-resistant scoring refers to scoring that does not disappear after heating. In non-heat-resistant scoring, visible scoring lines and invisible scoring lines are distinguished according to the degree of damage to the surface coating of the electrical steel sheet by the laser. When achieving heat-resistant scoring, the laser component can be achieved through double-sided scoring, high-frequency laser scoring, and repeated scoring, thereby integrating multiple scoring methods into one, realizing large-scale static scoring processing of electrical steel sheets, and uniform scoring lines across the entire width.

[0097] In the technical solution of the above embodiment, after the laser emits the laser, it passes through the connecting piece 46, the collimating piece 45, the steering piece 44, the focusing module 43 and the scanning head 42 in sequence. The collimating piece 45 can collimate the laser, the focusing module 43 can adjust the divergence angle of the laser, and the scanning head 42 can adjust the direction of the laser. The collimating piece 45, the focusing module 43 and the scanning head 42 cooperate with each other to realize diversified laser scoring of electrical steel sheets.

[0098] Preferably, the laser assembly further includes a cooling member, which is disposed on the support member 1 and connected to the laser. The cooling member may be a water chiller, which can provide cooling for the laser.

[0099] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the connection between the column, drive guard plate and shielding cover in some embodiments of the present application.

[0100] In some embodiments, the driving mechanism may include a lead screw, a guide rail, a motor, a nut and a slider.

The nut is arranged on the lead screw. The slider and the guide rail are slidably matched. The nut and the slider are both connected to the adjustment seat 8. The slider is installed on the adjustment seat 8, and the nut is snap-connected to the adjustment seat 8 in the direction of the lead screw axis. The motor drives the lead screw to rotate, which can enable the nut to drive the adjustment seat 8 to translate along the guide rail. The use of a lead screw and a nut to achieve transmission can improve transmission accuracy. The use of a guide rail and a slider to provide sliding guidance can improve the movement accuracy of the adjustment seat 8.

[0101] Preferably, the column 7 is arranged perpendicular to the supporting platform 2, so that the moving direction of the adjustment seat 8 is perpendicular to the supporting platform 2; the column 7 is located on the transfer side of the supporting platform 2, which can reduce the displacement of the lifting assembly when the supporting platform 2 rotates.

[0102] like Figure 2 and Figure 4 As shown, in some embodiments, the driving mechanism and the adjustment seat 8 are both located on the side of the column 7 facing the air knife module 5 .

[0103] During the structural arrangement, the air knife module 5 is located on the installation side, the air collector 6 is located on the adapter side, and the electromagnetic carrier 22 is located between the air knife module 5 and the air collector 6. The column 7 is installed on the adapter side, the adjustment seat 8 is closer to the air knife module 5 than the column 7, and the scanning assembly 4 is located above the electromagnetic carrier 22.

[0104] In the technical solution of the above embodiment, the adjustment seat 8 is located on the side of the column 7 facing the wind knife module 5. When the scanning component 4 is located above the electromagnetic carrier 22, the distance between the scanning component 4 and the column 7 can be reduced, thereby optimizing the force on the adjustment seat 8 and making the lifting and lowering of the adjustment seat 8 smoother.

[0105] like Figure 4 As shown, in some embodiments, the lifting assembly also includes a driving guard plate 9, which is arranged on the side of the column 7 facing the wind knife module 5 and is spaced apart from the column 7. The driving guard plate 9 is inserted into the adjustment seat 8.

[0106] The adjusting seat 8 is provided with a through slot, and the driving guard plate 9 is inserted into the through slot. Preferably, the cross-sectional profile of the driving guard plate 9 is smaller than the cross-sectional profile of the through slot.

[0107] In the technical solution of the above embodiment, the drive guard plate 9 is spaced apart from the column 7 and inserted into the adjustment seat 8, which not only enables the adjustment seat 8 to be smoothly connected to the drive mechanism, but also blocks the airflow from the wind knife module 5, providing protection for the drive mechanism, thereby providing good working conditions for the lead screw, guide rail, nut, and slider, and reducing the impact of airflow on transmission accuracy.

[0108] like Figure 4 As shown, in some embodiments, a detection component is also included, which includes a sensing piece, a ranging sensor and a photoelectric sensor. The sensing piece is arranged on the adjustment seat 8 and extends toward the column 7, and is used to indicate the position of the scanning component 4 in real time. The ranging sensor is arranged on the column 7 and is used to cooperate with the sensing piece to detect the position of the scanning component 4.

[0109] Preferably, the distance measuring sensor is a digital distance measuring sensor, the photoelectric sensor is a slot-type photoelectric sensor, there are multiple photoelectric sensors, and photoelectric sensors are provided at both ends of the column 7 along the length direction of the column 7 .

The sensing piece cooperates with the ranging sensor to detect the position of the scanning component 4; the sensing piece cooperates with the photoelectric sensor to limit the travel range of the scanning component 4 and prevent the adjustment seat 8 from exceeding the travel range, thereby improving safety.

[0111] Preferably, the detection assembly further includes a shielding cover 10, which is mounted on the upright post 7 and forms a housing space with the upright post 7. The housing space can accommodate the ranging sensor and the photoelectric sensor, protecting them from interference from external light, thereby improving detection accuracy. The shielding cover 10 is provided with a strip-shaped groove, the length of which is parallel to the length of the upright post 7. This provides a window for the sensor chip to enter the housing space, allowing the sensor chip to enter the housing space and cooperate with the ranging sensor and the photoelectric sensor for position detection and position limiting.

[0112] like Figure 1 As shown, in some embodiments, the support member 1 includes a scoring chamber 11, a receiving chamber 12, and an electronic control system 13.

The electronic control system 13 is mounted on the wall of the scoring chamber 11 and is connected to the carrier 2, the driver 3, the laser assembly, and the purge assembly to provide operational control.

[0113] The transfer side of the support platform 2 is hingedly connected to the bottom wall of the scoring chamber 11, and the driving member 3 is hingedly connected to the bottom wall of the accommodating chamber 12. The top of the driving member 3 extends into the scoring chamber 11 and is hingedly connected to the bottom of the support platform 2.

[0116] In the technical solution of the above embodiment, the scoring chamber 11 provides processing space for laser scoring of electrical steel sheets, forming a closed environment within the support member 1 to prevent the escape of fumes generated by laser scoring. The accommodating chamber 12 accommodates the driver 3, laser, and air supply components, thereby reducing external interference and improving the operating environment. The electronic control system 13 is installed on the side wall of the scoring chamber 11 and is connected to the support platform 2, driver 3, laser assembly, and purge assembly, respectively, facilitating direct control of the laser scoring process from outside the scoring chamber 11.

[0118] Preferably, a safety grating is provided in the chamber body, located at the opening of the chamber body and connected to the electronic control system 13. Under the control of the electronic control system 13, the grating can be switched between an open state and a closed state. When the safety grating is in the open state, the operation of the laser assembly is stopped when an object is detected to have entered the scoring chamber 11, thereby achieving a foolproof design and improving safety.

[0119] Preferably, the chamber door is an electric lift door, which can be a rolling shutter door. When open, it is housed at the top of the chamber opening and drops down when closed. The chamber body is equipped with dual control buttons, which are connected to the chamber door and the electronic control system 13, enabling simultaneous control of the door's elevation. The dual control buttons comprise two control buttons. During use, the scoring parameters are input through the electronic control system 13, causing the electric lift door to rise. The sample is placed on the electromagnetic carrier 22. The dual control buttons are then pressed simultaneously with both hands, causing the electric lift door to drop and initiate scoring. The use of dual control buttons further enhances foolproofing.
