Description

Technical Field

[0001] This application relates to the field of laser curing equipment technology, and in particular to a magnetic steel laser curing equipment and its process. Background Technology

[0002] Laser curing technology for magnetic steel plays a vital role in modern industrial production. As the manufacturing industry moves towards higher precision and efficiency, laser curing equipment for magnetic steel is constantly being innovated. Laser curing of magnetic steel is crucial for improving the performance and quality of magnetic steel, and it has wide applications in many fields such as electronics, machinery, and new energy, driving technological progress and product upgrades in related industries.

[0003] In laser curing equipment for magnetic steel, fumes, spatter, or dust from the environment generated during laser processing may adhere to the surface of the protective mirror, forming a contamination layer that reduces light transmittance and affects light penetration. Therefore, the protective mirror needs to be replaced regularly.

[0004] During laser changeover, a protective lens is typically installed on a mounting base, which is then inserted into the laser equipment. However, during this process, external airborne dust and even moisture can enter the laser equipment. The optical components in the laser curing equipment are extremely sensitive to contamination and moisture. Moisture entering the laser channel can cause corrosion of internal components, short circuits, and other problems, affecting the equipment's lifespan and stability. Furthermore, moisture condensation can cause laser beam scattering, refraction, or attenuation, reducing signal strength and even causing distortion, thus impacting measurement accuracy and processing quality. Similarly, dust entering the equipment can adhere to the optical components, causing contamination and affecting light transmission. Summary of the Invention

[0005] In order to improve the sealing of the laser equipment when replacing the protective lens, thereby reducing the possibility of moisture and dust entering the laser equipment, this application provides a magnetic steel laser curing equipment and its process.

[0006] The technical solution adopted in this application for a magnetic steel laser curing equipment and its process is as follows: A magnetic steel laser curing device includes a bracket and a laser emitter mounted on the bracket. The bracket includes an adjustment mechanism for adjusting the position of the laser emitter. A laser transmission channel is provided inside the laser emitter. An installation groove is provided on the side wall of the laser emitter. A placement groove is provided on the inner wall of the installation groove. The placement groove is connected to the laser transmission channel. A protective mirror and a holder for placing the protective mirror are placed in the placement groove. A sealing door is hinged to the opening of the mounting groove. A sealing ring for sealing the opening of the mounting groove is fixedly connected to the side of the sealing door facing the mounting groove. A screw for fixing the sealing door is rotatably connected to the sealing door. A screw hole for threaded connection of the screw is opened on the inner wall of the mounting groove.

[0007] By adopting the above technical solution, the protective mirror is embedded in the placement slot through the holder, forming an independent module. Replacement is only required by opening the sealed door and removing the holder; the entire laser emitter structure does not need to be disassembled, significantly reducing maintenance time. The sealing ring inside the sealed door, when closed, is compressed by the pre-tightening force of the door, causing it to elastically deform and fill the mounting groove, abutting against the holder, forming the first sealing barrier. This effectively prevents external air, moisture, and dust from entering the laser transmission channel while also stabilizing the position of the holder.

[0008] Preferably, the adjustment mechanism includes an X-rail, a Y-rail, and a Z-rail. A first slide block is fixedly connected to the Y-rail and slidably connected to the X-rail. A second slide block is fixedly connected to the Z-rail and slidably connected to the Y-rail. A third slide block is slidably connected to the Z-rail and a support rod is fixedly connected to the third slide block. The laser emitter is fixedly installed at the end of the support rod away from the Z-rail. The first slide block, the second slide block, and the third slide block are all electronically controlled components, controlled by the terminal panel, to realize independent or linked displacement adjustment of the laser emitter in the X, Y, and Z axes.

[0009] By adopting the above technical solution and through the independent sliding design of the X, Y and Z slide rails, the laser emitter can be adjusted to any position in three-dimensional space to adapt to the processing needs of workpieces of different shapes and sizes in the curing of magnetic steel. The electric slide base combined with the high-precision guide rail can improve the displacement resolution, ensure that the laser spot is accurately aligned with the processing area, and avoid insufficient or excessive curing due to positioning deviation.

[0010] Preferably, the laser emitter is provided with a sealing plate 1 and a sealing plate 2 for enhanced sealing. The laser emitter also has a sliding groove 1 and a sliding groove 2. The sliding groove 1 is located above the protective mirror, and the sealing plate 1 is slidably connected within the sliding groove 1. The sliding groove 2 is located below the protective mirror, and the sealing plate 2 slides within the sliding groove 2. The sealing plate 1 seals the laser transmission channel above the protective mirror, and the sealing plate 2 seals the laser transmission channel below the protective mirror. The laser emitter is provided with two sets of driving components to drive the sealing plate 1 and the sealing plate 2 to move respectively.

[0011] By adopting the above technical solution, before the staff needs to replace the protective mirror, the staff can drive the first sealing plate to the top of the protective mirror through the driving component to cover the upper section of the laser channel; the second sealing plate slides to the bottom of the protective mirror to cover the lower section of the laser channel. The two form a double sealing barrier on both sides of the protective mirror, which can independently block contaminants from entering the laser transmission channel when the staff opens the sealing door to replace the protective mirror.

[0012] Preferably, the driving assembly includes electromagnet one and electromagnet two. Electromagnet one is fixedly disposed on the side wall of the sliding groove one away from the laser transmission channel. Electromagnet two is fixedly disposed on the side wall of the sliding groove one opposite to electromagnet one. The laser emitter is provided with a switch for controlling the energized state of electromagnet one and electromagnet two.

[0013] By adopting the above technical solution, the drive component, through the coordinated design of electromagnet one, electromagnet two, and the switch, achieves rapid, contactless driving and precise control of the sealing plate one. During normal laser equipment use, electromagnet one is energized, and its magnetic force attracts one side wall of the sealing plate to adhere to electromagnet one, keeping the sealing plate one away from the laser transmission channel without affecting laser operation. When the operator prepares to open the sealing plate to replace the protective lens, under the action of the switch, electromagnet one is de-energized and electromagnet two is energized. At this time, the magnetic force on electromagnet two pulls the sealing plate two towards electromagnet two and adheres to it, thereby allowing the sealing plate one to pass through and cover the laser transmission channel.

[0014] Preferably, a groove is provided on the sealing plate, and a flexible pad is slidably connected in the groove. The flexible pad abuts against the side wall of the laser transmission channel, and a moving component is provided in the sealing plate for driving the flexible pad to move and fit against the laser transmission channel.

[0015] By adopting the above technical solution, when the sealing plate slides horizontally to the laser transmission channel, a gap is left between the flexible pad and the inner wall of the sliding groove to avoid friction between the sealing plate and the laser transmission channel, which would reduce the sealing effect in the long run. After the sealing plate is below the laser transmission channel, the flexible pad slides through the moving component and achieves a tight fit with the laser transmission channel through elastic deformation, thereby improving the sealing effect. The sealing effect is better than that of traditional rigid contact seals.

[0016] Preferably, the moving component includes a drive rod and a push rod. The push rod is fixedly connected to the bottom end of the flexible pad. A drive groove is formed inside the sealing plate. The push rod passes through the drive groove. A first inclined surface is formed at the bottom end of the push rod. The drive rod passes through and is slidably connected to the drive groove. A second inclined surface is provided on the drive rod. The first inclined surface and the second inclined surface abut against each other. A first spring is fixedly connected to one end of the drive rod located in the drive groove. The two ends of the first spring are respectively fixedly connected to the inner wall of the drive groove and the port of the drive rod. The end of the drive rod away from the first spring passes through the sealing plate and abuts against the electromagnet.

[0017] By adopting the above technical solution, when the sealing plate moves closer to the electromagnet, the drive rod first abuts against the electromagnet. During the movement of the sealing plate, the electromagnet pushes the drive rod to move into the groove to compress the first compression spring. The movement of the drive rod causes the second inclined surface to abut against and push the first inclined surface, thereby causing the push rod to move upward and drive the flexible pad to move upward to abut against and fit against the laser transmission channel.

[0018] Preferably, a second spring is sleeved on the push rod, and the two ends of the second spring are respectively fixedly connected to the flexible pad and the inner wall of the bottom of the groove.

[0019] By adopting the above technical solution, when the pushing force on the push rod is released, the second spring can pull the flexible pad downward, detach it from the laser transmission channel, and reduce the friction with the inner wall of the sliding groove.

[0020] Preferably, the switch is a button, which is disposed in a screw hole. The screw abuts against and pushes the button, and the button controls the energization of electromagnet one and electromagnet two.

[0021] By adopting the above technical solution, when the staff closes the sealed door and fixes the sealed door by screwing the screw into the screw hole, the screw abuts against and pushes the button to move inward. At this time, the first electromagnet is energized. When the staff screws the screw outward to open the sealed door, the button is reset when the screw moves away from the button, and the second electromagnet is energized.

[0022] The preferred method for replacing the protective lens is as follows: S1. First, turn off the laser power supply of the equipment and wait for the equipment to cool down for 15-30 minutes. Wear clean gloves. S2. Turn the screw to open the sealed door; S3. Pull out the container and close the sealing door; S4. Replace the protective lens; S5. Open the sealed door, insert the holder for the replaced protective mirror into the placement slot, close the sealed door, and tighten the screws to secure the sealed door.

[0023] By adopting the above technical solutions, the power is turned off and cooling is allowed to ensure that the laser completely stops emitting and the temperature of the optical components drops to a safe range, thus avoiding burns to operators from residual laser or high-temperature components. Wearing clean gloves can prevent hand oils and skin flakes from contaminating the surface of the protective mirror. Opening and closing the sealing door multiple times forms a physical isolation barrier, reducing the intrusion of external contaminants during the replacement process.

[0024] In summary, this application includes at least one of the following beneficial technical effects: The protective mirror is embedded into the placement slot through the holder, forming an independent module. When replacing it, only the sealing door needs to be opened and the holder removed to complete the operation. There is no need to disassemble the entire structure of the laser emitter, which greatly shortens the maintenance time. When the sealing door is closed, the sealing ring on the inside of the sealing door is compressed by the pre-tightening force of the sealing door, and undergoes elastic deformation to fill the installation groove and abut against the holder, forming the first sealing barrier. This effectively prevents external air, moisture and dust from entering the laser transmission channel, while also stabilizing the position of the holder. With the independent sliding design of X, Y and Z slide rails, the laser emitter can be adjusted to any position in three-dimensional space to adapt to the processing needs of workpieces of different shapes and sizes in magnetic steel curing. The electric slide base combined with high-precision guide rail can improve the displacement resolution and ensure that the laser spot is accurately aligned with the processing area, avoiding insufficient or excessive curing due to positioning deviation. Before the protective mirror needs to be replaced, the staff uses the drive assembly to move sealing plate one above the protective mirror, covering the upper section of the laser channel; sealing plate two slides below the protective mirror, covering the lower section of the laser channel. The two form a double sealing barrier on both sides of the protective mirror, which can independently block contaminants from entering the laser transmission channel when the staff opens the sealing door to replace the protective mirror.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a magnetic steel laser curing device, such as... Figure 1 As shown, the device includes a bracket 1 and a laser emitter 2 mounted on the bracket 1. The bracket 1 includes an adjustment mechanism for adjusting the position of the laser emitter 2. The adjustment mechanism includes an X-rail 4, a Y-rail 5, and a Z-rail 6. The X-rail 4 and Y-rail 5 are both horizontally arranged and relatively vertical. A first slide block 7 is fixedly connected to the lower end face of the middle position of the Y-rail 5. The first slide block 7 is electrically controlled to slide horizontally on the X-rail 4. The Z-rail 6 is vertically arranged. A second slide block 8 is fixedly connected to the bottom end of the Z-rail 6. The second slide block 8 is electrically controlled to slide horizontally on the Y-rail 5. A third slide block 9 is electrically controlled to slide along the height direction of the Z-rail 6. A support rod 3 is fixedly welded to the third slide block 9. The laser emitter 2 is fixedly mounted on the end of the support rod 3 away from the Z-rail 6. The first slide 7, the second slide 8, and the third slide 9 are all controlled by the terminal panel, supporting automatic operation of preset programs, reducing manual intervention and shortening processing time. The control mechanism can realize independent or linked displacement adjustment of the laser emitter 2 in the X, Y, and Z axes. Through the independent sliding design of the X slide rail 4, Y slide rail 5, and Z slide rail 6, the laser emitter 2 can be adjusted to any position in three-dimensional space, adapting to the processing needs of workpieces of different shapes and sizes in magnet curing. The electric slides, together with high-precision guide rails, can improve displacement resolution, ensuring that the laser spot is accurately aligned with the processing area, avoiding insufficient or excessive curing due to positioning deviation.

[0032] like Figure 2 and Figure 3As shown, a laser transmission channel 10 is provided inside the laser emitter 2. A mounting groove 11 is horizontally formed on one side wall of the laser emitter 2. A placement groove 12 is horizontally formed inward on the inner wall of the mounting groove 11, and the placement groove 12 is connected to the laser transmission channel 10. A protective mirror 13 and a holder 14 for placing the protective mirror 13 are provided in the placement groove 12. The holder 14 is inserted into the placement groove 12, and the position of the protective mirror 13 is aligned with the laser transmission channel 10. The diameter of the mounting groove 11 is larger than the diameter of the placement groove 12. A sealing door 15 is hinged to the opening of the mounting groove 11. A sealing ring 16 for sealing the opening of the mounting groove 11 is fixedly connected to the side of the sealing door 15 facing the mounting groove 11. A groove 37 is formed in the sealing door 15 inside the sealing ring 16. A rubber gasket is also provided on the inner wall of the groove 37. A desiccant or drying sheet can be placed in the groove 37. A screw 17 for fixing the sealing door 15 is rotatably connected to one side of the sealing door 15. A screw hole 18 for threaded connection of the screw 17 is provided on the inner wall of the mounting groove 11. When the sealing door 15 is closed, the sealing ring 16 inside the sealing door 15 abuts against the opening of the placement groove 12 and fits against the side wall of the container 14. The rubber gasket in the groove 37 also abuts against the side wall of the container 14. The drying sheet is positioned between the sealing door 15 and the mounting groove 11, improving the dryness within the mounting groove 11. The sealing door 15, rubber gasket, sealing ring 16, and desiccant together form the first sealing barrier, effectively preventing external air, moisture, and dust from entering the laser transmission channel 10 while also stabilizing the position of the container 14.

[0033] like Figure 2 and Figure 3 As shown, the protective mirror 13 is embedded in the placement slot 12 through the holding base 14, forming an independent module, which is convenient for staff to pick up and put in, and thus facilitates the replacement operation. When replacing, only the sealing door 15 needs to be opened and the holding base 14 needs to be taken out to complete the operation, without disassembling the entire structure of the laser emitter 2, which greatly shortens the maintenance time.

[0034] like Figure 3 As shown, the laser emitter 2 is equipped with a sealing plate 19 and a sealing plate 20 to enhance the sealing effect. The sealing plate 19 seals the laser transmission channel 10 above the protective mirror 13, and the sealing plate 20 seals the laser transmission channel 10 below the protective mirror 13. The laser emitter 2 has a sliding groove 21 located above the placement groove 12, which is horizontally oriented, and the sealing plate 19 slides within the sliding groove 21. The laser emitter 2 also has a sliding groove 22 located below the placement groove 12, which is horizontally oriented and parallel to the sliding groove 21 and the placement groove 12, and the sealing plate 20 slides within the sliding groove 22.

[0035] like Figure 3As shown, the laser emitter 2 is equipped with two sets of driving components 23 to drive the movement of sealing plate 19 and sealing plate 20 respectively. The two sets of driving components 23 have the same structure. This embodiment uses sealing plate 1 as an example. The driving component 23 includes electromagnet 1 24 and electromagnet 25. Electromagnet 1 24 is fixedly installed on the side wall of the sliding groove 21 away from the laser transmission channel 10. Electromagnet 25 is fixedly installed on the side wall of the sliding groove 21 opposite to electromagnet 1 24. Neither electromagnet 25 nor electromagnet 1 24 is in contact with the laser transmission channel 10. The laser emitter 2 is equipped with a switch for controlling the energization state of electromagnet 1 24 and electromagnet 25. The switch is a button 26, which is installed in the screw hole 18 and has a reset function. The button 26 controls the energization state of electromagnet 1 24 and electromagnet 25. When the staff closes the sealing door 15 and fixes the sealing door 15 by screwing the screw 17 into the screw hole 18, the screw 17 abuts against and pushes the button 26 to move inward. At this time, the electromagnet 1 24 is energized. When the staff screws the screw 17 outward to open the sealing door 15, the button 26 is reset when the screw 17 moves away from the button 26. At this time, the electromagnet 25 is energized.

[0036] like Figure 3 and Figure 4 As shown, a vertical groove 27 is formed in the sealing plate 19. A flexible pad 29 is slidably connected in the vertical direction within the groove 27. The flexible pad 29 can be made of materials such as silicone rubber or fluororubber. Multiple second springs 36 are provided in the groove 27. The two ends of the second springs 36 are fixedly connected to the bottom end of the flexible pad 29 and the inner wall of the bottom of the groove 27, respectively. Under the elastic pull of the multiple second springs 36, the flexible pad 29 leaves a gap with the inner wall of the groove 21 and does not contact it. Therefore, when the sealing plate 19 is driven to move under the magnetic force of the electromagnet 25, the wear of the flexible pad 29 is reduced. A moving component 28 is provided in the sealing plate 19 to drive the flexible pad 29 to move and fit against the side wall of the laser transmission channel 10.

[0037] like Figure 4As shown, multiple sets of moving components 28 are provided; in this embodiment, three sets are provided. The moving component 28 includes multiple push rods 31 and one drive rod 30. The number of push rods 31 is the same as the number of second springs 36. One end of each push rod 31 is fixedly welded to the bottom end of the flexible pad 29, and the second springs 36 are sleeved on the push rods 31. A drive groove 32 is provided in the bottom of the sealing plate 19, and the bottom end of each push rod 31 passes through the drive groove 32. A first inclined surface 33 is provided at the bottom end of each push rod 31. The drive rod 30 passes through the length of the sealing plate 19 and slides within the drive groove 32. Multiple push slots are provided on the drive rod 30, and the inner wall of one side of each push slot is provided with a second inclined surface 34. The push slots and push rods 31 cooperate with each other, and the first inclined surface 33 and the second inclined surface 34 abut against each other. One end of the drive rod 30 located in the drive groove 32 is fixedly connected to a first spring 35. The two ends of the first spring 35 are fixedly connected to the inner wall of the drive groove 32 and the port of the drive rod 30, respectively. The end of the drive rod 30 away from the first spring 35 passes through the sealing plate 19 and abuts against the electromagnet 25.

[0038] like Figure 3 and Figure 4 As shown, through the coordinated design of electromagnet 124, electromagnet 25 and the switching device, the sealing plate 19 is driven and controlled quickly and without contact. During normal use of the laser equipment, electromagnet 24 is energized, and its magnetic force attracts the side wall of the sealing plate 19 to adhere to the electromagnet 24, keeping the sealing plate 19 away from the laser transmission channel 10 without affecting the laser operation. When the operator is about to open the sealing plate to replace the protective lens 13, the electromagnet 24 is de-energized and electromagnet 25 is energized under the action of the switching device. At this time, the magnetic force on electromagnet 25 pulls the sealing plate 20 towards the electromagnet 25 and adheres to it, so that the sealing plate 19 passes through the laser transmission channel 10 and covers the laser transmission channel 10. As the sealing plate 19 approaches the electromagnet 25, the drive rod 30 first abuts against the electromagnet 25. During the movement of the sealing plate 19, the electromagnet 25 pushes the drive rod 30 into the slide groove 27 to compress the first compression spring. The movement of the drive rod 30 causes the second inclined surface 34 to abut against and push the first inclined surface 33, thereby causing the push rod 31 to move upward and drive the flexible pad 29 to move upward and abut against and fit against the laser transmission channel 10. The sealing plate 19 and the sealing plate 20 together form a double sealing barrier on both sides of the protective mirror 13. During the process of the staff opening the sealing door 15 to replace the protective mirror 13, contaminants can be independently blocked from entering the laser transmission channel 10, improving the sealing effect and reducing the possibility of contaminants entering the laser transmission channel 10 during the replacement of the protective mirror 13.

[0039] The replacement method for the protective lens 13 of the magnetic steel laser curing equipment is as follows: First, turn off the laser power supply and wait for the equipment to cool down for 15-30 minutes, then wear clean gloves; loosen screw 17 to open the sealing door 15; pull out the container 14 and close the sealing door 15; replace the protective lens 13; open the sealing door 15, insert the container 14 with the replaced protective lens 13 into the placement slot 12, close the sealing door 15, and tighten screw 17 to secure the sealing door 15, thus completing the replacement of the protective lens 13. Turning off the power and waiting for cooling ensures that the laser has completely stopped emitting and the temperature of the optical components has dropped to a safe range, preventing operators from being burned by residual laser light or high-temperature components. Wearing clean gloves prevents hand oils and skin flakes from contaminating the surface of the protective lens 13. Repeatedly opening and closing the sealing door 15 forms a physical isolation barrier, reducing the intrusion of external contaminants during the replacement process.

[0040] The implementation principle of this application embodiment is as follows: This magnetic steel laser curing equipment realizes the precise displacement adjustment of the laser emitter 2 in three-dimensional space through the adjustment mechanism composed of the X, Y, and Z three-axis electric slide rails and slide bases on the support 1, so as to adapt to the curing processing requirements of magnetic steels of different specifications. The laser emitter 2 has a placement slot 12 for placing the container 14. The protective mirror 13 forms an independent module with the container 14. Together with the sealing door 15 and sealing ring 16 hinged to the mounting slot 11, it forms the first seal. At the same time, the sealing plate 19 and sealing plate 20 inside the laser emitter 2 can form a double sealing barrier when the protective mirror 13 is replaced, driven by the drive component 23. The flexible pads 29 on the sealing plate 19 and sealing plate 20 can be tightly fitted with the laser transmission channel 10 through the moving component 28, which further improves the sealing effect and reduces the intrusion of contaminants. When the protective mirror 13 is replaced, it is only necessary to turn off the power and let it cool down. Then, the sealing door 15 can be opened and closed by turning the screw 17 and the container 14 can be removed and placed. The entire process does not require disassembling the laser emitter 2, which takes into account both the convenience of operation and the sealing of the equipment.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
