Description

Technical Field

[0001] The present application relates to the technical field of aluminum template cutting, and in particular to an aluminum template laser cutting device. Background Art

[0002] Aluminum formwork is aluminum alloy formwork, a new type of green building formwork system, which is used in temporary support structure systems for concrete pouring in construction. Compared with traditional wood formwork, aluminum alloy formwork has many advantages. Relevant research shows that compared with plywood with low quality level, construction efficiency and reuse rate, steel formwork with high additional cost and potential safety hazards, and plastic formwork with weak durability, low hardness and large temperature impact, aluminum formwork has the advantages of high quality, high efficiency and environmental protection. The high-quality aluminum formwork has high quality and long service life, with a turnover rate of up to 150-300 times, making it one of the building panels with the highest reuse rate; secondly, compared with steel formwork and wood formwork, aluminum formwork is light in weight, less dependent on auxiliary machinery, greatly reduces construction difficulty, and greatly improves work efficiency; in addition, aluminum has recycling value, and the residual value after scrapping is more than 30%. Aluminum recycling has great significance in both economic and environmental protection.

[0003] In specific engineering construction, according to different architectural design requirements, aluminum formwork needs to be made into various forms and shapes, and aluminum formwork raw materials are usually produced in standard fixed sizes, so aluminum formwork raw materials of various shapes need to be cut.

[0004] In the related art, a Chinese patent with application number CN202311047579.2 proposes an aluminum veneer laser cutting device, including a cutting head, a constraint mechanism and a reciprocating feeding mechanism. The constraint mechanism is symmetrically arranged and located on both sides of the cutting head and is used to constrain the state of the aluminum veneer on both sides of the cutting path. The reciprocating feeding mechanism reciprocates in the longitudinal direction and cyclically delivers the aluminum veneer to the cutting table. The aluminum veneer laser cutting device effectively reduces the possibility that the aluminum veneer is deformed by the cutting force and cutting temperature during the cutting process, thereby affecting the curvature of the aluminum veneer, improves the convenience of subsequent installation of the aluminum veneer and the aesthetics of the decorative effect of the aluminum veneer, and at the same time, combined with the precise and fast feeding of the reciprocating feeding mechanism, effectively improves the cutting efficiency, and the upper constraint mold and the lower constraint mold can stably and effectively constrain aluminum veneers of different sizes and different curvatures.

[0005] The above-mentioned related technologies have the following defects: when using a laser cutting device to cut shaped aluminum templates (such as curved templates, three-dimensional templates, etc.), the constraint mechanism will cause excessive local pressure on the aluminum template, causing deformation or damage to the aluminum template; and when fixing aluminum templates of different shapes and thicknesses, the operator is required to manually adjust the constraint mechanism, which requires more time and energy to ensure the correct position of the constraint mechanism, affecting the overall production efficiency and failing to meet mass production needs. Summary of the invention

[0029] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0030] An embodiment of the present application discloses an aluminum template laser cutting device. Refer to Figure 1 、 Figure 2 and Figure 3 . An aluminum template laser cutting device includes a laser head 1 on a cutting table 2 and a reciprocating feeding mechanism on one side of the cutting table 2. Opposite sides of the lower end surface of the cutting table 2 are fixedly connected with a plurality of mounting frames 3. Slide bars 4 are slidably arranged in each mounting frame 3. A driving mechanism for driving all or corresponding slide bars 4 to rise and lock or driving all slide bars 4 to synchronously descend is arranged on the cutting table 2; a vacuum chuck 41 is arranged at the upper end of the slide bar 4. A pressure sensor (not shown in the figure) is arranged in the middle of the upper end of the vacuum chuck 41. A vacuum pump 5 is arranged on one side of the cutting table 2. Air pipes are connected between the plurality of vacuum chucks 41 and the vacuum pump 5. A solenoid valve 55 is arranged on the air pipe. The pressure sensor and the solenoid valve 55 are controlled and connected; when the slide bar 4 rises to trigger the pressure sensor, the solenoid valve 55 is opened to cause the vacuum chuck 41 to adsorb and fix the aluminum template.

[0031] At least three rangefinders 6 are arranged on the upper end of the cutting table 2. The rangefinders 6 are specifically laser rangefinders or infrared rangefinders. The plurality of rangefinders 6 are distributed on two sides of a diagonal of the aluminum template and at least one other side. The rangefinders 6 are connected to a main controller of the driving mechanism. The main controller is configured to control the driving mechanism to stop driving the slide bar 4 corresponding to the rangefinder 6 to move up and lock when any rangefinder 6 detects that the position of the aluminum template reaches the set position.

[0032] When a laser cutting device is used to cut a shaped aluminum template (such as a curved template, a three-dimensional template, etc.), the reciprocating feeding mechanism of the device moves the aluminum template to a predetermined position of the cutting table 2. At this time, the driving mechanism is started, driving all the slide bars 4 to rise synchronously, and the vacuum suction cup 41 at the upper end of the slide bar 4 approaches the aluminum template. When the slide bar 4 rises to a certain height, the vacuum suction cup 41 contacts the aluminum template; at this time, the pressure sensor detects the contact pressure and is triggered, and the signal of the pressure sensor is transmitted to the solenoid valve 55, which is then opened and connected to the vacuum pump 5; the vacuum pump 5 starts to work, forming a negative pressure, and the vacuum suction cup 41 is connected to the vacuum pump 5 through the air pipe, adsorbing the aluminum template and fixing it on the cutting table 2 to ensure that no displacement occurs during the laser cutting process.

[0033] At the same time, at least three rangefinders 6 installed above the cutting table 2 monitor the position of the aluminum template in real time. When multiple vacuum suction cups 41 are jointly lifting the shaped aluminum template to the laser cutting station, a certain part of the aluminum template reaches the set position, and the rangefinder 6 corresponding to the part detects that the displacement of the part of the aluminum template meets the standard. At this time, the main controller controls the driving mechanism to make the slide bar 4 corresponding to the rangefinder 6 stop rising and lock it; until all rangefinders 6 detect that the displacement of the aluminum template meets the standard, the main controller controls the driving mechanism to make all slide bars 4 stop rising and lock it to ensure that the aluminum template is in the preset position during the cutting process. After the aluminum template is successfully adsorbed and fixed, the laser head 1 starts to start cutting the aluminum template, and the laser beam accurately cuts the aluminum template according to the preset cutting path and parameters.

[0034] Once the cutting is completed, the laser head 1 stops working, and the solenoid valve 55 is closed, releasing the vacuum suction cup 41 from adsorbing the aluminum template. The driving mechanism starts again, driving the multiple slide bars 4 to descend synchronously, moving the cut aluminum template out of the cutting table 2, and preparing for the next round of cutting operations.

[0035] The whole device integrates multiple automation components and precise control mechanisms, which not only reduces the difficulty and labor intensity of manual operation, improves production efficiency and product quality, but also can adapt to aluminum templates of different shapes and sizes to meet diverse cutting needs. It effectively improves the problem that when using laser cutting devices to cut aluminum templates, operators need to spend more time and energy to adjust the constraint mechanism, which affects the overall production efficiency and cannot meet the needs of mass production.

[0036] Specifically, refer to Figure 1 , Figure 2 and Figure 3The driving mechanism includes a rack 42 and a transmission gear 43 that are meshed and connected. The rack 42 is fixedly connected to the lower end of the slide bar 4 along the length direction of the slide bar 4. A driving rod 44 is coaxially arranged on the side of the transmission gear 43 away from the laser head 1. A second driving gear 45 is coaxially fixedly connected to the end of the driving rod 44 away from the transmission gear 43. The second driving gear 45 is rotatably arranged on the cutting table 2, and multiple second driving gears 45 are connected through synchronous belt transmission.

[0037] A driving motor 47 is fixedly connected to the cutting table 2, wherein two second driving gears 45 arranged opposite to each other are meshedly connected to the first driving gear 46, a transmission rod 48 is coaxially fixedly connected between the two first driving gears 46, wherein one of the first driving gears 46 is coaxially fixedly connected to the output end of the driving motor 47, and a locking assembly for locking the corresponding relative transmission gear 43 is provided on the driving rod 44 and the second driving gear 45.

[0038] One end of the rack 42 is fixedly connected to the lower end of the slide bar 4, and the transmission gear 43 is meshed with the rack 42. When the transmission gear 43 rotates, it will drive the rack 42 and the slide bar 4 to move along its length direction, thereby realizing the rise or fall of the vacuum suction cup 41 and the aluminum template. A transmission rod 48 is coaxially fixed between the first drive gears 46 located on the two opposite sides of the laser head 1, ensuring the synchronous rotation of the second drive gears 45 on both sides. And multiple second drive gears 45 are connected by synchronous belts to ensure the synchronous rotation of all second drive gears 45. This design enables all slide bars 4 to rise or fall at the same time, ensuring the stability of the aluminum template during the cutting process. The locking component is set to lock the transmission gear 43 after the slide bar 4 rises to the specified position, thereby ensuring the stable adsorption of the vacuum suction cup 41 and the aluminum template.

[0039] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The locking assembly includes an inner gear ring 431 which is sleeved on the driving rod 44 and meshed with the outer teeth of the transmission gear 43. The driving rod 44 is provided with a plurality of slide grooves 441 arranged along its length direction. Slide blocks 442 are slidably arranged in the slide grooves 441. One end of the plurality of slide blocks 442 close to the transmission gear 43 is fixedly connected to the inner gear ring 431. One end of the slide block 442 away from the inner gear ring 431 is fixedly connected to the outer gear ring 443. A slot 451 is provided on the second driving gear 45 for the outer gear ring 443 to be embedded. One end of the outer gear ring 443 close to the second driving gear 45 is fixedly connected to a shaft sleeve 444.

[0040] When the outer gear ring 443 is disengaged from the slot 451, the inner gear ring 431 is sleeved outside the transmission gear 43 and the shaft sleeve 444 is embedded between the driving rod 44 and the second driving gear 45;

[0041] The inner gear ring 431 and the support block are provided with a control component for driving the outer gear ring 443 to disengage from or insert into the slot 451 .

[0042] When the outer gear ring 443 is out of engagement with the slot 451, the inner gear ring 431 is sleeved outside the transmission gear 43 and meshes with the outer teeth of the transmission gear 43. At this time, due to the restraining effect of the inner gear ring 431, the transmission gear 43 cannot rotate, thereby realizing the locking function. At the same time, the shaft sleeve 444 is embedded between the driving rod 44 and the driving gear, providing a stable support for the entire locking assembly. When the outer gear ring 443 is out of engagement with the transmission gear 43 and is moved toward the driving gear to be embedded in the slot 451, during this process, the slider 442 slides in the slide slot 441, driving the inner gear ring 431 to be out of engagement with the transmission gear 43, while the outer gear ring 443 gradually approaches the driving gear and finally embeds in the slot 451. When the outer gear ring 443 is completely embedded in the slot 451, the rotation of the driving gear will drive the outer gear ring 443 and the entire locking assembly to rotate together. Since the inner gear ring 431 is no longer in engagement with the transmission gear 43 at this time, the transmission gear 43 can rotate freely, thereby realizing the unlocking function.

[0043] And, refer to Figure 1 , Figure 2 and Figure 3 The control component includes an electromagnet 31 fixedly connected to the mounting frame 3, an annular lever 432 fixedly connected to the inner gear ring 431, a magnet 433 is arranged at the position of the annular lever 432 corresponding to the electromagnet 31, and the electromagnet 31 is connected to a current controller 32, and the current controller 32 is configured to alternately change the current passing through the electromagnet 31.

[0044] Specifically, when the transmission gear 43 needs to be locked, the current controller 32 makes the electromagnet 31 magnetized and generates suction force on the magnet 433, so that the outer gear ring 443 is disengaged from the slot 451, and the inner gear ring 431 is meshed with the transmission gear 43 to achieve the locking function. When the transmission gear 43 needs to be unlocked, the current controller 32 changes the current direction in the electromagnet 31, so that the electromagnet 31 generates sufficient magnetic repulsion to repel the magnet 433; since the electromagnet 31 is fixed on the driving gear, the magnet 433 will be subjected to a force in the direction of the driving gear, driving the outer gear ring 443 to move in the direction of the slot 451 and gradually embedding therein. Once the outer gear ring 443 is completely embedded in the slot 451, the inner gear ring 431 is no longer meshed with the transmission gear 43, and the transmission gear 43 can rotate freely to achieve the unlocking function. In this way, through the interaction between the electromagnet 31 and the magnet 433 and the precise control of the current controller 32, the rapid locking and unlocking function of the transmission gear 43 is achieved.

[0045] And, refer to Figure 1 , Figure 2 and Figure 3The current controller 32 is controlled and connected with the driving mechanism and the distance meter 6. When any distance meter 6 detects that the position of the aluminum template reaches the set position, the driving mechanism stops driving the sliding rod 4 corresponding to the distance meter 6 to move up, and the current controller 32 controls the electromagnet 31 to be energized and magnetically attracted to the magnet 433. Under the action of the magnetic force of the electromagnet 31 and the magnet 433, the outer gear ring 443 corresponding to the sliding rod 4 is disengaged from the slot 451, the inner gear ring 431 is sleeved on the outside of the transmission gear 43, and the shaft sleeve 444 is embedded between the driving rod 44 and the second driving gear 45.

[0046] In this way, when any distance meter 6 detects that the position of the aluminum template reaches the set position, the driving mechanism stops driving the sliding bar 4 corresponding to the distance meter 6 to move upward, and the current controller 32 corresponding to the distance meter will adjust the current in the corresponding electromagnet 31, so that the electromagnet 31 and the corresponding magnet 433 generate a magnetic force of attraction; under the action of the magnetic force of attraction, the outer gear ring 443 gradually disengages from the slot 451, and the inner gear ring 431 meshes with the transmission gear 43, realizing the one-to-one locking function of the sliding bar 4. The current controller 32 is connected with the driving mechanism and the distance meter 6, so that the laser cutting device can monitor and adjust automatically in real time, ensuring the safe adsorption and precise cutting of the aluminum template.

[0047] Furthermore, refer to Figure 1 ,and Figure 3 The upper end of the slide rod 4 is fixedly connected with a mounting block 412 , the mounting block 412 is provided with a ball head 413 , the ball head 413 is sleeved with a ball sleeve 414 , and the middle part of the vacuum suction cup 41 is fixedly connected to the outer peripheral wall of the ball sleeve 414 .

[0048] The ball head 413 provided on the mounting block 412 and the ball sleeve 414 sleeved on the ball head 413 form a ball joint connection. This connection mode allows the vacuum suction cup 41 to be fine-tuned and rotated within a certain range while maintaining connection with the slide bar 4, so as to adapt to aluminum templates of different shapes and sizes. At the same time, the ball joint connection can help the vacuum suction cup 41 to better fit the surface of the aluminum template, thereby improving the adsorption effect.

[0049] And, refer to Figure 3 , the ball head 413 and the mounting block 412 are threadedly connected (not shown in the figure). The threaded connection allows a quick and stable connection between the ball head 413 and the mounting block 412. When the vacuum suction cup 41 system needs to be replaced or maintained, the operator can easily remove or install it by rotating the ball head 413 without using special tools or complicated steps; at the same time, the threaded connection usually has a certain adjustable range, which means that during the installation process, the operator can fine-tune the relative position between the ball head 413 and the mounting block 412 as needed to ensure that the vacuum suction cup 41 can absorb the aluminum template at the best angle and position. This adjustability improves the adaptability and flexibility of the equipment.

[0050] And, refer to Figure 1 The air pipe includes a first air pipe 51 connected to the vacuum pump 5 and multiple second air pipes 54 connected to multiple vacuum suction cups 41. A multi-joint 53 is connected between the first air pipe 51 and the second air pipe 54, and a solenoid valve 55 is arranged on the second air pipe 54.

[0051] By dividing the air pipe system into a first air pipe 51 and a second air pipe 54, and connecting them with a one-turn multi-joint 53, a modular design is achieved. This design makes the assembly and maintenance of the air pipe system more convenient, and is also convenient for expansion or adjustment according to actual needs; at the same time, the solenoid valve 55 is set on the second air pipe 54, so that each vacuum suction cup 41 can independently control its adsorption state. When the pressure sensor detects that the vacuum suction cup 41 is in contact with the aluminum template and triggers a signal, the corresponding solenoid valve 55 will open, allowing the gas in the second air pipe 54 to flow, so that the vacuum suction cup 41 generates negative pressure and adsorbs the aluminum template. This precise control ensures that the vacuum suction cup 41 is adsorbed at the correct time and position, improving the accuracy and efficiency of the cutting operation.

[0052] At the same time, refer to Figure 1 , a regulating valve 52 is provided on the first air pipe 51, and the operator can also indirectly control the negative pressure generated by the vacuum pump 5 through the regulating valve 52. This is particularly important for aluminum templates of different materials, sizes and shapes, because different aluminum templates may require different adsorption forces to ensure stable adsorption. By adjusting the regulating valve 52 on the first air pipe 51, the output pressure of the vacuum pump 5 can be accurately controlled, thereby meeting the adsorption requirements of various aluminum templates.

[0053] The implementation principle of the aluminum template laser cutting device in the embodiment of the present application is:

[0054] When a laser cutting device is used to cut a shaped aluminum template (such as a curved template, a three-dimensional template, etc.), the reciprocating feeding mechanism of the device moves the aluminum template to a predetermined position of the cutting table 2. At this time, the driving mechanism is started, driving all the slide bars 4 to rise synchronously, and the vacuum suction cup 41 at the upper end of the slide bar 4 approaches the aluminum template. When the slide bar 4 rises to a certain height, the vacuum suction cup 41 contacts the aluminum template; at this time, the pressure sensor detects the contact pressure and is triggered, and the signal of the pressure sensor is transmitted to the solenoid valve 55, which is then opened and connected to the vacuum pump 5; the vacuum pump 5 starts to work, forming a negative pressure, and the vacuum suction cup 41 is connected to the vacuum pump 5 through the air pipe, adsorbing the aluminum template and fixing it on the cutting table 2 to ensure that no displacement occurs during the laser cutting process.

[0055] At the same time, at least three rangefinders 6 installed above the cutting table 2 monitor the position of the aluminum template in real time. When multiple vacuum suction cups 41 are jointly lifting the shaped aluminum template to the laser cutting station, a certain part of the aluminum template reaches the set position, and the rangefinder 6 corresponding to the part detects that the displacement of the part of the aluminum template meets the standard. At this time, the main controller controls the driving mechanism to make the slide bar 4 corresponding to the rangefinder 6 stop rising and lock it; until all rangefinders 6 detect that the displacement of the aluminum template meets the standard, the main controller controls the driving mechanism to make all slide bars 4 stop rising and lock it to ensure that the aluminum template is in the preset position during the cutting process. After the aluminum template is successfully adsorbed and fixed, the laser head 1 starts to start cutting the aluminum template, and the laser beam accurately cuts the aluminum template according to the preset cutting path and parameters.

[0056] Once the cutting is completed, the laser head 1 stops working, and the solenoid valve 55 is closed, releasing the vacuum suction cup 41 from adsorbing the aluminum template. The driving mechanism starts again, driving the slide bar 4 to descend synchronously, and moving the cut aluminum template out of the cutting table 2 to prepare for the next round of cutting operation.

[0057] The whole device integrates multiple automation components and precise control mechanisms, which not only reduces the difficulty and labor intensity of manual operation, improves production efficiency and product quality, but also can adapt to aluminum templates of different shapes and sizes to meet diverse cutting needs. It effectively improves the problem that when using laser cutting devices to cut aluminum templates, operators need to spend more time and energy to adjust the constraint mechanism, which affects the overall production efficiency and cannot meet the needs of mass production.
