Description

TECHNICAL FIELD

[0001] The application relates to the technical field of laser cutting, in particular to a laser processing device for isolating switch production. BACKGROUND

[0002] In the production process of the isolating switch, the copper plate is a core raw material of the conductive part of the isolating switch, and the laser cutting precision directly determines the assembly precision and electrical performance of the isolating switch.

[0003] The laser processing device is a kind of metal cutting equipment and is a key equipment in the production of the isolating switch. When the existing laser processing device performs laser metal cutting on the copper plate, a fixed grid workbench is usually used to support the processed workpiece. After the laser cutting passes through the copper plate, it will continue to impact the supporting grid at the bottom, thereby generating intense sparks. The sparks are easy to rebound after impacting the grid, and impact the precise components such as the laser cutting head and the protective mirror, thereby causing damage to the components. Meanwhile, the protective mirror is easy to be contaminated after long-term use. The existing cleaning method mainly relies on manual disassembly and wiping, which is complicated and inefficient. Moreover, manual wiping is easy to damage the coating of the protective mirror, and it is difficult to ensure the wiping cleanliness, thereby causing secondary pollution. SUMMARY

[0006] Preferably, tension springs are fixedly connected to both sides of the slide plate, and the other end of the tension springs is fixedly connected to the outer wall of the adsorption box. Adsorption magnets are provided on both sides of the slide plate, and a magnetic plate is provided at the end of the upper plate. The magnetic plate has opposite magnetic poles to the adsorption magnets.

[0007] Preferably, an air suction box is connected to the outer wall of the adsorption box, a one-way valve is provided inside the air suction box, a baffle is slidably connected through the air suction box, a through opening is provided on the baffle, the baffle is fixedly connected to the slide plate, and a cleaning mechanism is provided on the adsorption box.

[0008] Preferably, the cleaning mechanism includes two covering boxes fixedly connected to the adsorption box. A left rotating roller and a right rotating roller are rotatably connected inside the two covering boxes respectively. A release roller is sleeved on the left rotating roller, and a take-up roller is sleeved on the right rotating roller. A dustproof cloth strip is provided between the release roller and the take-up roller.

[0009] Preferably, a connecting disc is fixedly connected to the end of the right rotating roller, and multiple torsion spring shafts are installed inside the connecting disc. Each of the multiple torsion spring shafts is fixedly connected to a flipping plate. Multiple blocking components are fixedly connected inside the connecting disc, and the multiple blocking components contact the corresponding flipping plates respectively. A gear is rotatably connected through the inside of the connecting disc, and multiple push plates are fixedly connected to one end of the gear located inside the connecting disc.

[0010] Preferably, a limiting rail is fixedly connected to the outer wall of one of the two covering boxes, a rack is slidably connected to the limiting rail, the rack is meshed with a gear, and a pressure spring is provided inside the limiting rail.

[0012] Preferably, a protective cover is installed at the end of the laser cutting head, and a protective mirror is provided inside the laser cutting head.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This device, as a type of metal cutting equipment, uses a second double-headed telescopic rod to drive the pressure rollers on the upper and lower plates to tightly fit the upper and lower surfaces of the copper plate, providing support for the cutting space. Because the bottom of the copper plate is hollowed out, combined with the limiting and supporting effect of the pressure rollers, the high-temperature sparks and molten slag generated when the laser cuts through the copper plate fall directly to the bottom of the main body of the equipment. This avoids the backlash phenomenon caused by traditional grid worktables, effectively preventing backlash sparks and slag from impacting precision components such as the laser cutting head and protective mirror, reducing the risk of component damage and secondary pollution. When the laser cutting head cuts the copper plate, the adsorption box pre-cleans the uncut area of ​​the copper plate, effectively removing impurities such as floating dust, oxide scale powder, and fine metal dust from the surface of the copper plate. This reduces the generation of sparks and fumes during laser cutting from the source, lowering the probability of contamination of the laser cutting head and protective mirror.

[0014] 2. This device uses multiple telescopic rods to move the adsorption box, which in turn seals the adsorption box and opens the suction box. At the same time, it uses wedges, racks and pinions to switch the clean section of the dustproof cloth strip. It automatically cleans the protective mirror by using negative pressure suction and wiping with the clean cloth strip. Compared with manual cleaning of the protective mirror, this cleaning method is more convenient and efficient, improving the cutting efficiency of the entire equipment. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1 - Figure 13 A laser processing device for producing disconnect switches includes a main body 1, a movable swing arm 2 slidably connected to the main body 1, a transverse drive component 28 slidably connected to the movable swing arm 2, a laser cutting head 3 mounted on the transverse drive component 28, a follow-up pre-processing mechanism fixedly connected to the movable swing arm 2, the follow-up pre-processing mechanism including a second double-headed telescopic rod 12 fixedly connected to both sides of the movable swing arm 2, an upper plate 17 and a lower plate 13 fixedly connected to the upper and lower sides of the second double-headed telescopic rod 12 respectively, multiple pressure rollers 19 rotatably connected between the upper plate 17 and the lower plate 13 on both sides, a negative pressure suction device 14 fixedly connected to the outer wall of the lower plate 13, multiple telescopic rods 18 fixedly connected to the outer walls of the upper plates 17 on both sides, an adsorption box 11 fixedly connected to the end of the multiple telescopic rods 18, an air suction pipe 16 connected to the negative pressure suction device 14, the other end of the air suction pipe 16 connected to the interior of the adsorption box 11, and a sliding plate 8 slidably connected to the adsorption box 11.

[0019] Both sides of the slide plate 8 are fixedly connected with tension springs 9, and the other end of the tension springs 9 is fixedly connected to the outer wall of the adsorption box 11. Both sides of the slide plate 8 are provided with adsorption magnets, and the end of the upper plate 17 is provided with a magnetic plate 10, which has opposite magnetic poles to the adsorption magnets.

[0020] An air suction box 27 is connected to the outer wall of the adsorption box 11. A one-way valve is installed inside the air suction box 27. A baffle 26 is slidably connected through the air suction box 27. A through hole 32 is opened on the baffle 26. The baffle 26 is fixedly connected to the slide plate 8. A cleaning mechanism is provided on the adsorption box 11.

[0021] In this embodiment, this device, as a type of metal cutting equipment, first pushes the copper plate 4 into the main body 1 of the device during actual use. Then, through the retraction of multiple first double-headed telescopic rods 5, the clamping member 6 is driven to securely clamp and fix the copper plate 4 (e.g., ...). Figure 1 As shown, after the copper plate 4 is clamped and fixed, the second double-headed telescopic rods 12 on both sides of the equipment retract synchronously, which respectively drive the two sets of pressure rollers 19 on the upper plate 17 and the lower plate 13 to fit tightly against the upper and lower surfaces of the copper plate 4. After the above operation is completed, the laser cutting head 3 can be started, and the high-energy laser generated by the laser cutting head 3 can be used to perform metal cutting on the copper plate 4.

[0022] During the laser metal cutting process of the laser cutting head 3, since all components related to the pressure rollers 19, such as the second double-headed telescopic rod 12, the upper plate 17, and the lower plate 13, are fixedly connected to the movable swing arm 2, when the movable swing arm 2 drives the laser cutting head 3 to move back and forth and adjust the cutting position, the above-mentioned components will move synchronously with the movable swing arm 2. During this process, the multiple pressure rollers 19 fixed on the upper plate 17 and the lower plate 13 will roll and follow the movement of the laser cutting head 3 on the surface of the copper plate 4. Moreover, the installation position of the laser cutting head 3 is exactly within the space defined by the multiple sets of pressure rollers 19, so that the cutting range of the laser cutting head 3 is precisely limited to the middle area of ​​two adjacent sets of pressure rollers 19. The pressure rollers 19 support the space where the copper plate 4 is cut. When the laser emitted by the laser cutting head 3 completes the laser cutting operation on the copper plate 4 and passes through the copper plate 4, the activated negative pressure suction device 14 will remove the laser through the negative pressure suction generated. The fumes generated during laser cutting are prevented from drifting upwards onto the surface of the protective mirror 37 of the laser cutting head 3, thus avoiding contamination of the protective mirror 37 and preventing laser spot distortion and cutting energy attenuation, ensuring cutting accuracy. At the same time, since the cutting range of the laser cutting head 3 is limited to a fixed clamping space by multiple sets of pressure rollers 19, and the bottom of the copper plate 4 is hollowed out, the high-temperature sparks and molten slag generated when the laser cutting head 3 cuts through the copper plate 4 will fall directly to the bottom of the main body 1 of the equipment. Unlike traditional laser cutting equipment, where sparks bounce back after hitting the worktable grid, this effectively avoids the backlash of sparks and slag hitting the laser cutting head 3, the protective mirror 37, and other precision components of the equipment, reducing the risk of component damage. It also reduces secondary pollution caused by spark backlash, further ensuring cutting accuracy and equipment lifespan. It also prevents the grid from being damaged by long-term spark impact, reducing equipment maintenance frequency and costs.

[0023] Since the second double-headed telescopic rod 12, the upper plate 17, the lower plate 13 and other components are all fixedly connected to the movable swing arm 2, when the movable swing arm 2 drives the laser cutting head 3 to move and cut different areas of the copper plate 4, the cutting space limited by the multiple sets of pressure rollers 19 will be adjusted synchronously with the movement of the movable swing arm 2, and the cutting range of the laser cutting head 3 will always be limited and pressed until the cutting operation of the entire copper plate 4 is completed, ensuring stable cutting accuracy throughout the process.

[0024] When the movable swing arm 2 drives the laser cutting head 3 to perform cutting operations from back to front, part of the negative pressure suction generated by the negative pressure fan inside the negative pressure suction device 14 is conducted to the adsorption box 11 through the suction pipe 16, so that the adsorption box 11 generates a stable negative pressure suction, which pre-suctions and cleans the areas on the copper plate 4 that have not yet been laser-cut. This can effectively adsorb and remove various impurities from the surface of the copper plate 4, such as floating dust in the workshop environment, oxide powder that has fallen off the surface of the copper material, and fine metal dust remaining before laser cutting. Pre-suction cleaning of the surface of the copper plate 4 can reduce the generation of sparks, metal fumes, and oily aerosols caused by the high temperature burning of impurities during laser cutting, and reduce the pollution and damage to the entire laser cutting head 3 component. (It should be noted that, referring to...) Figure 13 The structure is designed such that the top of the adsorption box 11 is provided with an inclined slope. When impurities are drawn to the top of the adsorption box 11 by the negative pressure suction, they will slide down the inclined slope into the suction pipe 16 under the combined action of gravity and negative pressure airflow. Then, they will be drawn into the negative pressure suction device 14 for collection through the suction pipe 16. The negative pressure suction device 14 is provided with an openable cleaning door. When the impurities collected inside the negative pressure suction device 14 are full, the operator can easily clean the inside of the negative pressure suction device 14 through the opening and closing door.

[0025] Example 2: Please refer to Figure 1 - Figure 13 The cleaning mechanism includes two covering boxes 20 fixedly connected to the adsorption box 11. The two covering boxes 20 are respectively rotatably connected to a left rotating roller 21 and a right rotating roller 24. A release roller 22 is sleeved on the left rotating roller 21, and a take-up roller 23 is sleeved on the right rotating roller 24. A dustproof cloth strip 25 is provided between the release roller 22 and the take-up roller 23.

[0026] A connecting disc 30 is fixedly connected to the end of the right-hand roller 24. Multiple torsion spring shafts are installed inside the connecting disc 30. Each torsion spring shaft is fixedly connected to a flipping plate 35. Multiple blocking members 36 are fixedly connected inside the connecting disc 30. Each blocking member 36 contacts the corresponding flipping plate 35. A gear 31 is rotatably connected through the inside of the connecting disc 30. Multiple push plates 15 are fixedly connected to one end of the gear 31 inside the connecting disc 30.

[0027] A limiting rail 34 is fixedly connected to one of the outer side walls of the two covering boxes 20. A rack 33 is slidably connected to the limiting rail 34. The rack 33 is meshed with the gear 31. A pressure spring is installed inside the limiting rail 34.

[0028] Two wedge-shaped parts 29 are fixedly connected to the transverse drive component 28. The first double-headed telescopic rod 5 is fixedly connected to both sides of the main body 1. Clamping parts 6 are fixedly connected to both sides of the first double-headed telescopic rod 5. A copper plate 4 is installed inside the main body 1.

[0029] A protective cover 7 is installed at the end of the laser cutting head 3, and a protective mirror 37 is installed inside the laser cutting head 3.

[0030] In this embodiment, as the equipment is used for an extended period, when the surface of the protective lens 37 of the laser cutting head 3 needs cleaning due to impurities, the quick-release structure inside the laser cutting head 3 can be controlled to allow the protective cover 7 to detach from the laser cutting head 3 autonomously (this is prior art and will not be elaborated further). After the protective cover 7 detaches autonomously, since the equipment is in a stopped state and no copper plate 4 is placed inside the main body 1, the detached protective cover 7 will fall to the bottom space of the main body 1, avoiding interference with subsequent cleaning operations. After the protective cover 7 detaches autonomously from the laser cutting head 3, the operator can adjust the laser cutting head 3 to a preset cleaning position using the transverse drive 28, and then control the multiple multi-section telescopic rods 18 to retract. When the multiple multi-section telescopic rods 18 retract, they will drive the entire adsorption box 11 to move closer to the laser cutting head 3. (It should be noted that the suction pipe 16 adopts a telescopic flexible hose structure, and its length can be adaptively adjusted with the movement of the adsorption box 11 to ensure stable transmission of negative pressure suction.) When the adsorption box 11 moves closer to the laser cutting head 3, the adsorption magnet on the slide plate 8 will gradually detach from the magnetic plate 10. When the distance between the two reaches the preset value, the adsorption magnetic force generated between them will completely disappear. At this time, under the pulling force of the tension spring 9, the slide plate 8 moves into the interior of the adsorption box 11 to achieve a seal and blockage of the adsorption box 11, so that the bottom of the adsorption box 11 no longer generates negative pressure suction, and avoids the adsorption box 11 from accidentally sucking up impurities during the cleaning process.

[0031] As the slide plate 8 moves into the suction box 11, it will drive the baffle 26 fixedly connected to it to move synchronously. When the baffle 26 moves to the preset position, the through hole 32 will completely enter the suction box 27. At this time, the suction box 27, which was originally in a closed state, will start to be open. Since the suction box 11 has been sealed by the slide plate 8, and the suction box 27 is in a conductive state, the negative pressure suction force transmitted by the negative pressure suction device 14 to the inside of the suction box 11 through the suction pipe 16 will be fully received by the suction box 27, ensuring that the suction box 27 can generate enough negative pressure suction force for the cleaning operation of the protective mirror 37.

[0032] Driven by the retraction of the multi-section telescopic rod 18, the adsorption box 11 continues to move closer to the laser cutting head 3. During this process, the rack 33 will contact the left wedge-shaped part 29 (see reference). Figure 8The left wedge 29 overcomes the elastic force of the internal pressure spring of the limiting rail 34, pushing the entire rack 33 downward. When the rack 33 is pushed downward, it will drive the gear 31 meshing with it to rotate clockwise four times. When the gear 31 rotates clockwise, it will drive multiple push plates 15 to rotate clockwise and contact the corresponding flip plate 35. When the flip plate 35 is pushed clockwise by the push plate 15 and flips to the right, the right flip direction of the flip plate 35 is limited by the blocking part 36. Therefore, the flip plate 35 will drive the connecting plate 30 to rotate together. When the connecting plate 30 rotates, it will drive the right rotating roller 24 to rotate synchronously. The right rotating roller 24 drives the take-up roller 23 to rotate and perform a take-up action on the dustproof cloth strip 25. Correspondingly, the left rotating roller 21 and the unloading roller 22 perform a take-up action synchronously. Under this linkage operation, the part of the dustproof cloth strip 25 that is about to be used to wipe the protective mirror 37 will be automatically switched to the previously unused clean part to ensure that there is no secondary pollution during the wiping process and to ensure the cleaning effect of the protective mirror 37.

[0033] As the adsorption box 11 continues to move, when the fully conductive suction box 27 comes into contact with the surface of the protective mirror 37, the negative pressure suction generated by the suction box 27 will precisely suction and clean the dust and impurities on the surface of the protective mirror 37. Since the adsorption box 11 is in a continuous moving state, after the suction box 27 moves past the surface of the protective mirror 37, the switched clean dustproof cloth strip 25 will immediately perform a secondary wipe and clean the surface of the protective mirror 37 to ensure the removal of any remaining fine impurities. Once the dustproof cloth strip 25 has finished wiping the surface... After the protective mirror 37 is wiped and detached from the protective mirror 37, the rack 33 will contact the right wedge 29. Referring to the contact linkage principle between the left wedge 29 and the rack 33, the gear 31 will drive the right roller 24 to rotate again through the connecting plate 30. When the right roller 24 rotates, it will drive the take-up roller 23, the release roller 22 and the left roller 21 to move synchronously, roll up the dustproof cloth strip 25 that has been used to wipe the protective mirror 37, and release the new unused clean part to prepare for subsequent wiping or the next cleaning operation.

[0034] After the cleaning operation is completed, the multi-section telescopic rod 18 can be controlled to extend, pushing the adsorption box 11 back to the initial working position. During the process of the adsorption box 11 returning to the initial position, the clean part of the dustproof cloth strip 25 will come into contact with the surface of the protective mirror 37 again for a second wipe. Subsequently, the suction box 27 will perform a second negative pressure suction on the surface of the protective mirror 37 to further remove residual impurities. By using a clean dustproof cloth strip 25 to wipe the protective mirror 37, the secondary contamination of the surface of the protective mirror 37 caused by the reuse of the dustproof cloth strip 25 can be effectively avoided, ensuring the cleanliness of the protective mirror 37 and guaranteeing laser transmission efficiency and cutting accuracy. After the surface of the protective mirror 37 has been automatically cleaned, the operator can install a new protective cover 7 on the laser cutting head 3, and the equipment can be put back into production.

[0035] It should be noted that, referring to the above linkage principle, when the rack 33 is pressed down, driving the gear 31 to rotate clockwise, it will drive the connecting plate 30 to rotate synchronously through the push plate 15 and the flip plate 35. When the rack 33 moves downward to its limit stroke, under the reset force of the pressure spring inside the limit rail 34, the rack 33 will move upward. When the rack 33 moves upward, it will drive the gear 31 to rotate counterclockwise. When the gear 31 rotates counterclockwise, it will push the flip plate 35 to flip to the left. At this time, the direction of the flip plate 35 to flip to the left is not limited by the blocking part 36. Therefore, the flip plate 35 only flips itself and will not drive the connecting plate 30 to rotate. Correspondingly, the right-turning roller 24 and the take-up roller 23 will not perform the winding action of the dustproof cloth strip 25, avoiding waste caused by the accidental winding of the dustproof cloth strip 25.

[0036] It should be noted that a matching clamping mechanism (not shown in the figure) is provided at the rear of the main body 1 of the equipment. When the entire copper plate 4 is pushed into the main body 1 of the equipment, the front of the copper plate 4 is clamped and fixed by the clamping component 6, and the rear of the copper plate 4 is clamped and fixed simultaneously by the matching clamping mechanism, so as to realize the bidirectional positioning of the copper plate 4 from front to back, avoid the copper plate 4 from moving or shifting during the laser cutting process, further ensure the cutting accuracy, and meet the high-precision processing requirements of the copper plate 4 component in the production of disconnect switches.

[0037] It should be noted that when the dustproof cloth strip 25 is completely used up, the operator can remove the release roller 22 from the left rotating roller 21 to replace the dustproof cloth strip 25. Specifically, for a single complete cleaning operation of the protective mirror 37, the required length of the dustproof cloth strip 25 is 50-80mm, and the overall length of the matching roll of dustproof cloth strip 25 is 3-5m. Based on the amount used per cleaning, one roll of dustproof cloth strip 25 can meet the cleaning needs of the protective mirror 37 for 60 cleanings. At the same time, considering the actual operating conditions of the equipment, the cleaning cycle of the protective mirror 37 is relatively long, so there is no need to frequently replace the dustproof cloth strip 25. This can effectively reduce equipment maintenance costs and operator workload, improve the continuous operation efficiency of the equipment, and adapt to the working conditions of mass production of disconnect switches.

[0038] It should be noted that the cutting space range defined by the multiple sets of pressure rollers 19 is relatively large compared to the laser cutting head 3. When the laser cutting head 3 performs straight cutting or irregular cutting on the copper plate 4, it will not come into contact with the multiple sets of pressure rollers 19.

[0039] It should be noted that the magnetic force of the adsorption magnet and the magnetic plate 10 is relatively small. The magnetic force generated between them only provides adsorption and positioning for the slide plate 8 and will not affect the laser cutting operation.

[0040] It should be noted that a one-way valve is installed inside the suction box 27, and the flow direction is from the inside of the suction box 27 to the inside of the adsorption box 11. This can prevent backflow of air and avoid the impurities being drawn out. At the same time, a slag storage box (not shown in the figure) can be installed at the bottom of the main body 1 of the equipment, so that the slag and sparks generated during cutting can directly enter the slag storage box.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
