Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a high-precision laser cutting component and a cutting system. Background Art

[0002] Laser cutting technology, a shining jewel of modern manufacturing, plays an irreplaceable role in a wide range of fields, including metalworking, automotive manufacturing, aerospace, and electronic equipment, thanks to its high precision, high efficiency, and diverse processing capabilities. However, the optical path must be adjusted before processing; otherwise, the material will not be cut through or the cutting effect will be poor. This is because most laser cutting machines use a flying optical path system. Only the perfect coordination of the laser tube, reflector mounts (single, double, and triple reflectors), focusing lens, and corresponding adjustment devices can achieve optimal results.

[0003] Patent document CN217701805U discloses a reflector mount adjustment structure for a laser cutting machine, comprising a right-angle base, a reflector mounting plate, a laser assembly, and a light-transmitting plate. The right-angle base further comprises an inclined surface and two right-angled surfaces. The reflector mounting plate is threaded with four fine-tuning bolts, each fitted with a spring. The first end of the fine-tuning bolt is threaded onto the inclined surface, and the spring presses the reflector mounting plate against the second end of the fine-tuning bolt.

[0004] In the prior art of the above-mentioned patent document, the optical path needs to be adjusted before laser cutting processing. The traditional adjustment method is to first adjust the laser current to below 8mA (<50% power), then stick double-sided tape on the first dimming target hole, emit light, and observe whether the photoelectric device is in the center of the dimming target. Subsequent adjustments to the second and third reflectors require sticking double-sided tape. If an error occurs during operation, causing the double-sided tape to contact the reflective lens, there will be glue marks left on the reflective lens, which can easily cause the lens to be contaminated with dust, affecting the light path reception and output. In addition, each time the glue is applied and removed, the operation is cumbersome and reduces the adjustment time. Summary of the Invention

The compensation module includes a placement box 21 set in the dimming target 14, and a compensation spring 22 fixedly connected to the placement box 21. The other end of the compensation spring 22 is fixedly connected to a push plate 23. A dimming cardboard 24 is set in the placement box 21. When the loading module completes loading, the compensation module automatically compensates the dimming cardboard 24 to complete the preparation stage for the next loading.

[0023] The loading module includes a push rod 26 movably mounted on the dimming target 14 and a handle 27 fixedly mounted on the end of the push rod 26 . A dimming slot 29 is provided in the dimming target 14 . The top of the dimming target 14 is threadedly connected to a first positioning bolt 210 , and the placement box 21 is located below the first positioning bolt 210 .

[0024] Specifically, before laser cutting, dimming is required. The traditional dimming method is to stick double-sided tape on the dimming target hole of the first reflector, point out the light, and observe whether the photoelectric is in the center of the dimming target. If it is in the center, the adjustment of the first reflector is completed. When adjusting the second reflector, move the second reflector to the closest point to the first reflector, stick double-sided tape on the mark, and then move the second reflector to the farthest point from the first reflector, and point the mark again. If the two points are offset, use the adjustment screw of the second reflector to make the near and far end light spots completely overlap. At this time, the adjustment of the second reflector is completed. The adjustment of the third reflector only needs to ensure that the light spot at the laser nozzle outlet is centered and without offset. In the above operations, you need to stick and tear off the double-sided tape. If the tape accidentally touches When the reflective lens is applied to the adhesive, the adhesive trace is easily contaminated with dust and affects the optical path. In addition, the adhesive application process requires not only finding the tape head, but also cutting it with scissors and then pasting it, which is a cumbersome process. In the present invention, the frame mechanism also includes a base 1, an adjusting rod 11, a support plate 12, an adjusting screw 15, and tension spring locking screws 16 and 17. The base 1 is used to fix and support the adjusting rod 11, and the adjusting rod 11 can be a telescopic rod for adjusting the height of the mounting plate 13, or by changing the fixed height of the base 1. The support plate 12 is used to install the mounting plate 13. The number of adjusting screws 15 is three, which is used to adjust the position of the mounting plate 13. , 17 is used to disassemble and assemble the reflective lens, which are all existing technologies and are not described in detail here; the compensation module also includes a first mounting groove 2 provided inside the dimming target 14, and the placement box 21 is installed in the first mounting groove 2. Both sides of the placement box 21 are provided with through grooves 25 adapted to the dimming cardboard 24 for loading. The loading module also includes a first return spring 28 sleeved on the outer peripheral side of the push rod 26, one end of the first return spring 28 is fixedly connected to the dimming target 14, and the other end is fixedly connected to the handle 27 for assisting the push rod 26 to reset. When loading, the push rod 26 can be moved by pushing the handle 27, and the straightness of the push rod 26 The diameter is adapted to the through slot 25, and the dimming cardboard 24 can be pushed into the dimming slot 29 for testing, and then the push rod 26 is reset. At this time, under the elastic force of the compensation spring 22, the push plate 23 will push a dimming cardboard 24 into the loading position to complete the material preparation. A loading slot is provided above the placement box 21 for replenishing the dimming cardboard 24, and the top of the dimming target 14 is threadedly connected with a first positioning bolt 210 for fixing the placement box 21. Compared with the traditional method of sticking double-sided tape, the present invention only needs to push to complete the preliminary preparation of dimming, the operation is more convenient, and the influence of the double-sided tape on the reflector is avoided.

[0025] Example 2: Please refer to Figures 3 to 6 , further comprising a connecting frame 3 movably mounted on the dimming target 14 , and a calibration cross ring 32 fixedly connected to one end of the connecting frame 3 .

[0026] The device further includes a locking mechanism, which includes a first gear rod 41 fixedly connected to the other end of the connecting frame 3, and a driven column 42 movably mounted in the dimming target 14. The driven column 42 has a driven groove 47 on its surface, a locking column 45 fixedly connected to the bottom of the driven column 42, and a locking hole 46 on the push rod 26. The light modulating target 14 further includes a positioning mechanism, which includes a fixing plate 51 movably disposed in the light modulating target 14 , and an elastic column 52 fixedly connected to one end of the fixing plate 51 .

[0027] The bottom of the dimming target 14 is threadedly connected to a lifting screw 6 , and a step 62 is provided in the dimming target 14 .

[0028] The device further includes a blanking mechanism, which includes a gear 7 meshing with the first gear rod 41 and a second gear rod 71 meshing with the lower side of the gear 7. A blanking plate 72 is fixedly mounted on one end of the second gear rod 71. A blanking trough 74 is provided in the dimming target 14.

[0029] An engaging groove 73 adapted to the blanking plate 72 is defined in the dimming target 14 , and the bottom of the blanking plate 72 is located below the top of the blanking groove 74 .

[0030] Specifically, a second positioning bolt 31 is threadedly connected to the connecting frame 3 for positioning the connecting frame 3. The locking mechanism also includes a driving groove 4 opened in the dimming target 14 and a round block 43 fixedly installed on the top of the driven column 42, a second return spring 44 sleeved on the outer peripheral side of the driven column 42, one end of the second return spring 44 is fixedly connected to the round block 43, and the other end is fixedly connected to the dimming target 14, wherein the first gear rod 41 is movably installed in the driving groove 4. When the connecting frame 3 is not moved, one end of the first gear rod 41 is in the driven groove 47. At this time, the locking column 45 is in the locking hole 46, which is used to lock the push rod 26 to prevent the staff from accidentally touching the handle 27 during use of the machine, resulting in the problem of the dimming cardboard 24 blocking the light path. On the basis of Example 1, in the dimming Before loading the light, you can first move the connecting frame 3 so that the calibration cross ring 32 moves to the center of the dimming target 14. At this time, the first gear rod 41 moves with the connecting frame 3 and separates from the driven column 42. Under the elastic force of the second return spring 44, the driven column 42 moves upward, so that the locking column 45 and the locking hole 46 are separated, and the limit on the push rod 26 is released. Then loading and point shooting can be carried out. Compared with observing with the naked eye whether the point shooting position is at the center point, the calibration cross ring 32 can assist the staff to make a more accurate judgment and improve the dimming accuracy. Correspondingly, when the dimming is completed, the first gear rod 41 is reset, and the driven groove 47 is inclined. Under the drive of the first gear rod 41, the driven column 42 is driven to move downward, so that the locking column 45 and the locking hole 46 coincide with each other, and the locking is completed. Furthermore, after the loading is completed, the dimming is carried out in a point-to-point manner. During the dimming process, repeated adjustment is often required. At this time, the jacking screw 6 can be screwed to lift the dimming cardboard 24 upward so that the bottom of the dimming cardboard 24 is flush with the step 62, so that the dimming cardboard 24 can be reused. An interference block 61 is also fixed on the jacking screw 6. The distance between the interference block 61 and the bottom of the dimming target 14 is equal to the height of the step 62, which is convenient for the staff to adjust. During the first point-to-point shooting, the dimming cardboard 24 is positioned by the step 62 to maintain its stability; a second mounting groove 5 is also provided inside the dimming target 14, and the fixing plate 51 is movably installed in the second mounting groove 5, and the other end of the elastic column 52 is fixedly connected to the part of the dimming target 14 in the second mounting groove 5, for adjusting the fixing plate 51 To reset, when the calibration cross ring 32 moves to the center of the dimming target 14, the first gear rod 41 will drive the gear 7 to rotate during the movement, so that the gear 7 drives the second gear rod 71 to move, so that the blanking plate 72 moves into the fitting groove 73. As the first gear rod 41 continues to move, it will drive the top of the fixed plate 51 to rotate the fixed plate 51. When the first gear rod 41 is driven, the fixed plate 51 is in a vertical state. When the dimming paperboard 24 is lifted up and the second burst is performed, the upper side of the dimming paperboard 24 contacts the fixed plate 51. The fixed plate 51 can be used to position the lifted dimming paperboard 24. The dimming target 14 is also provided with a compensation groove 53 adapted to the fixed plate 51 for compensating for the rotation stroke of the fixed plate 51. When the first and second gears 41 and 41 are in contact with the mounting plate 72, the fixing plate 51 is reset and the blanking plate 72 is moved. The fixing plate 51 releases the positioning of the dimming paperboard 24, and the blanking plate 72 drives the dimming paperboard 24 to move, so that the dimming paperboard 24 is moved out through the blanking slot 74 to complete the blanking. It should be noted that the width of the fitting slot 73 is greater than the width of the blanking plate 72, ensuring that when the blanking plate 72 contacts the dimming paperboard 24, the fixing plate 51 has a certain flip angle, which is fully separated from the dimming paperboard 24 to avoid interference in operation. Figure 1 As shown, the high-precision laser cutting component refers to the second reflector in the cutting system, but in actual production and processing, the dimming target structure of this application can be integrated into other reflectors.

[0031] When the first gear 41 is in the upright position, the first gear 41 is in the upright position, and the second gear 41 is in the upright position, so that the first gear 41 is in the upright position, and the second gear 41 is in the upright position, so that the first gear 41 is in the upright position, and the second gear 41 is in the upright position, so that the first gear 41 is in the upright position, and the second gear 41 is in the upright position, so that the first gear 41 is in the upright position, so that the first gear 41 is in the upright position, The placing box 21 moves to the dimming slot 29. At this time, the new dimming paperboard 24 will be pushed to the upper material level by the pushing plate 23 under the elastic force of the compensation spring 22. At this time, the dimming paperboard 24 in the dimming slot 29 is positioned by the step 62, and then spot dimming is performed. When spot dimming is needed again, the lifting screw 6 can be turned to make the bottom of the dimming paperboard 24 in the dimming slot 29 flush with the bottom of the discharge slot 74. At the same time, the upper side of the dimming paperboard 24 will be positioned by the vertical fixing plate 51 to ensure stability during the second adjustment. When the dimming is completed or the dimming paperboard 24 needs to be replaced, the connecting frame 3 is reset. At this time, the first gear rod 41 is reset, and the limit on the fixing plate 51 is released. Under the action of the elastic column 52, the fixing plate 51 is reset, and the discharge plate 72 drives the dimming paperboard 24 to discharge it through the discharge slot 74. Then the connecting frame 3 is moved to move the calibration cross ring 32 to the center of the dimming target 14, and the above operation is repeated.
