Description

Technical Field

[0002] Laser engraving machine is an advanced equipment that uses laser to engrave the materials that need to be engraved. The laser inside the laser engraving machine is its core. Generally speaking, compared with mechanical engraving machines and other traditional manual engraving methods, laser engraving machines have a wider range of uses, higher engraving accuracy, and faster engraving speed. Laser engraving machines use a laser of a certain wavelength as a light source, refract the light source twice through a two-dimensional galvanometer, and shape and focus the refracted light beam, and then use the laser energy points formed by the shaped and focused light beam on the surface of the object to engrave preset patterns and texts on the surface of the object. It is often used to engrave plates or other materials.

[0003] When laser engraving is performed, there will be problems with thermal deformation. Thermal deformation will cause unevenness or asymmetry of the engraved surface, affecting the accuracy of the final work. The heat generated by high temperature may cause cracks, bubbles or stratification in certain materials during the engraving process, reducing the availability of the material. At the same time, the laser engraving machine usually requires two sets of equipment to flip the plate and load and unload the material. The two sets of equipment require more physical space for installation and operation. The additional space occupation may affect the layout and workflow of the workshop, reducing space utilization and production efficiency. In view of the above problems, a multifunctional laser engraving machine is proposed to solve them. Summary of the invention

The present invention drives the flipping component to adsorb the plate on the placement plate through the left moving component, and the plate is accurately transferred to the calibration component through the cooperation of the first threaded rod and the first moving slide rail. The right moving component and the flipping component work together to complete the flipping of the plate after engraving, so that the engraved plate can be quickly processed or handled in the next step. The rapid flipping of the plate ensures the smooth progress of subsequent processes and avoids delays caused by improper operation. The scissor lift lifts the plate to be processed to the calibration height, and the roller conveyor line receives the engraved plate and conveys it to the next process.

Accurate positioning avoids the plate from shifting during the engraving process, thereby ensuring the accuracy of laser engraving. Whether it is detailed engraving or overall pattern, precise positioning can ensure the integrity and detail of the engraved pattern, avoid deviation and error, and improve the quality of the finished product. Accurate positioning ensures that each processing position of the plate can be correctly aligned with the laser path of the engraving machine, thereby reducing the time for repeated inspections and adjustments, reducing repositioning and adjustments caused by deviation, and improving the efficiency of the entire processing process. Through precise positioning, errors or incomplete engravings caused by plate deviation during the engraving process are avoided, which can significantly reduce the scrap rate, reduce the reprocessing or discarded plates due to deviations, and save resources and costs.

Through the dual functional integration of loading and unloading and flipping, automatic processing of multiple links can be realized in the same system, reducing the conversion time between equipment and systems. It not only optimizes the operations of loading and unloading and flipping, but also significantly improves production efficiency, processing accuracy, production consistency and safety. The integration of such an automated system can significantly reduce manual intervention and reduce production costs.

[0018] 4. The present invention adopts a composite purification scheme of wind knife and filter bag dust collection by setting up a closed-loop cooling component.

No redundant description is made in this embodiment. A closed-loop cooling component 9 is fixedly installed on the upper surface of the substrate 1 below the calibration component 4, and a moving component 2 is fixedly connected to the left and right sides of the calibration component 4 on the upper surface of the substrate 1. The two groups of moving components 2 are distributed perpendicular to each other, and a flipping component 3 is installed above the two groups of moving components 2.

[0024] In this embodiment, the working principle and workflow of the device are as follows: first, the plate to be engraved is placed on the placement plate 6, and then the moving component 2 on the left drives the flip component 3 above it to move to the placement plate 6, and then the moving component 2 on the left absorbs the plate and transports it to the calibration component 4 through the moving component 2 on the left. The calibration component 4 works to center the plate, and then the laser engraving machine 10 is controlled by an external controller to engrave the plate. During engraving, the closed-loop cooling component 9 works to cool the engraved surface and blow away the dust. After one side is engraved, the controller controls the laser engraving machine 10 to move to the edge of the frame 401, and then the flip component 3 on the left side will engrave the engraved plate The material is adsorbed and lifted to the control position. At this time, the flip component 3 on the left drives the plate to rotate ninety degrees, so that the unengraved side faces the flip component 3 on the right. The flip component 3 on the right is driven by the moving component 2 on the right to approach the plate and adsorb the plate. Then the flip component 3 on the right drives the plate to rotate ninety degrees so that the engraved side faces upward, and then the plate is placed in the calibration component 4 for calibration through the rotation of the screw rod. Then the laser engraving machine 10 engraves the other side. After the engraving is completed, the laser engraving machine 10 is reset, and the flip component 3 on the right adsorbs the plate.

At the same time, the dual-axis motor 306 drives the fixed seat 307 to rotate, thereby realizing the flipping of the plate and increasing the versatility of the equipment.

[0031] In this embodiment, the working principle and working process of the flipping component 3 are as follows: the flipping component 3 moves under the drive of the moving component 2. After moving to the appropriate position, the second motor 311 drives the second threaded rod 310 to rotate. When the second threaded rod 310 rotates, the moving plate 304 moves through the threaded cooperation, so that the suction cup 309 is close to the plate and adsorbs the plate through negative pressure. When flipping the plate, first, the second motor 311 drives the second threaded rod 310 to rotate to lift the plate to a suitable height. The output ends on both sides of the dual-axis motor 306 drive the fixed seat 307 to rotate, thereby driving the mounting frame 308 to rotate, so that the plate rotates ninety degrees.

[0035] In this embodiment, the working principle and working process of the calibration component 4 are as follows: the plate is transported to the top of the placement seat 403 through the flipping component 3, and then the output end of the electric cylinder 409 pushes the sliding bar 406 to move along the guide rod 405. When the sliding bar 406 on one side is moving, the sliding bar 406 on the other side will be pulled by the rotating bar 410 and the two first connecting rods 411 to move synchronously relative to each other. At this time, the extrusion plates 408 on both sides will first contact the plate to center the plate in the front and back directions. When the two groups of sliding bars 406 move, the inclination angles of the two second connecting rods 412 on both sides become larger, and the plate is squeezed through the connection position of the two second connecting rods 412. The synchronous movement of the two sides is used to center the left and right directions of the plate. The ball 404 at the bottom is used to reduce friction, so that the plate can be smoothly positioned. After the positioning is completed, it is engraved by the laser engraving machine 10.

The heat exchange plate 914 is a prior art, such as the fin-type heat exchanger commonly used in air conditioners in life, and will not be elaborated in detail in this embodiment.

[0038] Reference Figure 5 As shown, a first air collecting hood 902 is fixedly connected to the front side of the installation box 901, two air inlet pipes 903 are fixedly connected to the end of the first air collecting hood 902, and first main air diffusion pipes 904 are fixedly connected to the ends of the two air inlet pipes 903. The first main air diffusion pipes 904 are fixedly connected to the air outlet 906 through a plurality of first branch air diffusion pipes 905.

[0040] In this embodiment, the working principle and working process of the closed-loop cooling component 9 are as follows: when laser engraving is performed, the axial flow fan 908 is started to blow the air flow toward the first air collecting hood 902. The air flow passes through the air inlet pipe 903, the first main air diffuser pipe 904 and the first branch air diffuser pipe 905 in sequence, and then blows toward the plate being engraved through the air outlet 906. When the axial flow fan 908 is working, negative pressure will be generated at the air inlet 913 (the axial flow fan promotes the air to flow axially through the rotating impeller. When the air is accelerated through the impeller, according to the Bernoulli principle, the increase in flow rate causes the pressure to decrease, thereby forming a negative pressure at the air inlet. This is the prior art). The airflow blown out of the air outlet 906 is sucked in by the negative pressure at the air inlet 913, and then is introduced into the second air collecting hood 909 through the second branch air diffusion pipe 912, the second main air diffusion pipe 911 and the air outlet pipe 910 in sequence. The airflow mixed with dust is filtered by the dust collecting filter bag 907 to retain the dust, and these high-temperature airflows will be cooled when passing through the heat exchange plate 914, and then blown out by the axial flow fan 908 to cool the plate.
