DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4As shown, a laser engraving device comprises a workbench 1; a laser body 11 is installed on the top of the workbench 1; two groups of limit rods 12 are slidably connected to the middle of the workbench 1; a frame plate 13 is fixedly connected to the top of the limit rod 12; a first spring column 14 is fixedly connected to the inner wall of the workbench 1; a top plate 15 is rotatably connected to the output end of the first spring column 14; two groups of first bayonet pins 16 are fixedly connected to the middle of the top plate 15; a vertical plate 17 is fixedly connected to the middle of the frame plate 13, and the top plate 15 is arranged at the bottom of the vertical plate 17; when working, the staff needs to install the workbench 1 in the working area, and then align the material to be processed with the inner wall of the workbench 1, and start the switch of the laser body 11 so that it processes the material, and by arranging a rotatable top plate 15 in the middle of the workbench 1, when the workbench 1 is working, the top plate 15 is in a vertical state, and supports the frame plate 13 with its top, At the same time, when it is necessary to clean the impurities inside the workbench 1, the staff can pull the top plate 15 outward to separate the first latch 16 from the middle of the workbench 1, and the middle part of the rubber rod 4 is stretched and generates a reaction force. After the top plate 15 is separated from the vertical plate 17, the frame plate 13 as a whole will lose its supporting force and show a downward trend, and slide in the middle of the workbench 1 with the help of two sets of limit rods 12. At this time, the staff can clean the impurities accumulated inside the workbench 1. This step is combined with the setting of the frame plate 13 that can slide up and down, so that after the laser body 11 completes the processing of the material, because the middle part of the workbench 1 is embedded, it is difficult for the staff to clean its inner groove or corner area. The long-term accumulation of impurities on the inner wall of the workbench 1 makes the middle part of the workbench 1 uneven, which makes it easy for subsequent materials to tilt and shake during processing, thereby improving the accuracy of subsequent materials when being laser processed.

[0025] like Figure 1 , 2As shown in Figure 4, two groups of rails 2 are fixedly connected to the end of the frame plate 13; two groups of rotating shafts 21 are rotatably connected to the middle of the workbench 1; a tooth block 22 is fixedly connected to the middle of the rotating shaft 21, and the tooth block 22 is meshed with the rail 2; a connecting member 23 is fixedly connected to the end of the rotating shaft 21; a pressing plate 24 is provided at the end of the connecting member 23; when working, by providing two groups of rails 2 in the middle of the frame plate 13, when the frame plate 13 is in the working state, the pressing plate 24 will be close to the top of the workbench 1 and squeeze and fix the material, and when the frame plate 13 as a whole moves downward, it will synchronously belt The two groups of rail members 2 are moved to move. Since the rail members 2 and the tooth blocks 22 are meshed, the tooth blocks 22 will move synchronously. At the same time, the connecting member 23 drives the pressure plate 24 to separate from the top of the workbench 1 and the surface of the material. This is repeated. This step is combined with the pressure plate 24 to fix part of the material, thereby reducing the problem of position deviation and affecting the processing accuracy when some materials are laser processed in the middle of the workbench 1. At the same time, the tooth blocks 22 can improve the synchronization of the movement of the pressure plate 24 and the frame plate 13, and improve the stability of the pressure plate 24 when in use.

[0026] like Figure 5 As shown, a second spring column 3 is fixedly connected to the middle of the connecting member 23; a second bayonet 31 is fixedly connected to the output end of the second spring column 3; a slide plate 32 is fixedly connected to the end of the pressing plate 24, and the slide plate 32 is slidably arranged in the middle of the connecting member 23; a plurality of groups of holes 33 are fixedly connected to the middle of the sliding plate 32, and the holes 33 and the ends of the second bayonet 31 are arranged in a shape matching; when working, by arranging the sliding plate 32 at the end of the pressing plate 24, the end of the second bayonet 31 will be stuck in the middle of the sliding plate 32 and fix the pressing plate 24 as a whole, and the staff needs to disassemble or lengthen the pressing plate 24 as a whole. When adjusting the degree, the staff can pull the second pin 31 upwards, so that the end of the second pin 31 will be separated from the slide plate 32 after the force is applied, and the middle part of the second spring column 3 will be elongated, and then the slide plate 32 can be pushed to slide in the middle part of the connecting piece 23, and the position can be adjusted. This step cooperates with the set slide plate 32 to enhance the flexibility of the pressing plate 24 in squeezing and fixing the material, and reduces the problem that the edge of some materials is short and it is difficult for the pressing plate 24 to fix it. At the same time, it is convenient to disassemble the pressing plate 24 as a whole, thereby reducing the adhesion of impurities in the middle part of the pressing plate 24.

[0027] like Figure 4 and 5As shown, a plurality of rubber rods 4 are fixedly connected to the middle of the pressing plate 24; a ball 41 is fixedly connected to the end of the rubber rod 4; during operation, by arranging a plurality of rubber rods 4 in the middle of the pressing plate 24, when the pressing plate 24 squeezes and fixes the material, the plurality of rubber rods 4 in the middle will contact and work with the material, and at the same time, the raised ball 41 will retract inwardly. This step, in conjunction with the rubber rods 4 and the ball 41 made of soft material, can enhance the friction force of the pressing plate 24 when it contacts the material, and the raised ball 41 can reduce the problem of misalignment and sliding in the middle of the workbench 1 when processing materials such as cloth.

[0028] like Figure 3 As shown, a reinforcement rod 5 is fixedly connected to the middle part of the rail member 2; a scraper 51 is connected to the torsion spring in the middle part of the reinforcement rod 5, and the scraper 51 is arranged in contact with the middle part of the tooth block 22; during operation, by arranging the reinforcement rod 5 in the middle part of the rail member 2, when the tooth block 22 rotates, the scraper 51 will scrape off the impurities accumulated in the middle part of the tooth block 22, and at the same time, there are many protruding and hardened impurities in the middle part of the tooth block 22, which can be pushed and cleaned with the help of the torque between the reinforcement rod 5 and the scraper 51. This step cooperates with the scraper 51 to improve the cleanliness of the middle part of the tooth block 22, reduce the adhesion time of more impurities in the middle part of the tooth block 22, reduce its corrosion cycle on impurities, and improve the service life of the tooth block 22.

[0029] like Figure 3 As shown, two sets of wheels 6 are rotatably connected in the middle of the top plate 15, and the wheels 6 are in contact with the bottom of the vertical plate 17; when working, two sets of wheels 6 are set in the middle of the top plate 15, so that when the top plate 15 is pulled out, the wheels 6 will roll in the middle of the vertical plate 17. This step can reduce the wear between the top plate 15 and the vertical plate 17 under the action of rotating the wheels 6, and reduce the subsequent wear, which makes the top plate 15 support the vertical plate 17 and cause shaking.

[0030] like Figure 2 As shown, two groups of rubber pads 7 are fixedly connected to the middle of the workbench 1, and the rubber pads 7 are arranged at the bottom of the frame plate 13; when working, by arranging two groups of rubber pads 7 in the middle of the workbench 1, when the supporting force is lost and it falls, the bottom of the frame plate 13 will directly contact the top of the rubber pads 7, and with the help of the rubber pads 7 made of soft material, the force of the frame plate 13 falling is buffered. This step cooperates with the rubber pads 7 to reduce the direct impact of the bottom of the frame plate 13 on the inner wall of the workbench 1, which will cause deformation at the edge of the frame plate 13 over a long period of time, thereby requiring frequency division repair.

[0031] The working principle is as follows: after the workbench 1 is installed in the working area, the material to be processed is then aligned with the inner wall of the workbench 1, and the switch of the laser body 11 is started to process the material. A rotatable top plate 15 is provided in the middle of the workbench 1, so that when the workbench 1 is working, the top plate 15 is in a vertical state, and the frame plate 13 is supported by its top. When the impurities inside the workbench 1 need to be cleaned, the staff can pull the top plate 15 outward to separate the first latch 16 from the middle of the workbench 1, and the middle of the rubber rod 4 is stretched and a reaction force is generated. After the top plate 15 is separated from the vertical plate 17, the frame plate 13 as a whole will be lost. The support force is removed, and it shows a downward trend, and slides in the middle of the workbench 1 with the help of two sets of limit rods 12. At this time, the staff can clean up the impurities accumulated inside the workbench 1. By setting two sets of rails 2 in the middle of the frame plate 13, when the frame plate 13 is in a working state, the pressure plate 24 will be close to the top of the workbench 1 and squeeze and fix the material. When the frame plate 13 moves downward as a whole, it will synchronously drive the two sets of rails 2 to move. Because the rails 2 and the tooth blocks 22 are meshed, the tooth blocks 22 will move synchronously, and at the same time, the pressure plate 24 is driven to separate from the top of the workbench 1 and the surface of the material under the action of the connecting member 23, and this is repeated. By A slide plate 32 is provided at the end of the pressing plate 24, so that the end of the second latch 31 will be stuck in the middle of the slide plate 32 and fix the pressing plate 24 as a whole. When the staff needs to disassemble the pressing plate 24 as a whole or adjust the length, the staff can pull the second latch 31 upward, so that the end of the second latch 31 will be separated from the slide plate 32 after the force is applied, and the middle part of the second spring column 3 will be stretched, and then the slide plate 32 can be pushed to slide in the middle of the connecting member 23 and adjust the position. By arranging multiple groups of rubber rods 4 in the middle of the pressing plate 24, when the pressing plate 24 squeezes and fixes the material, the multiple groups of rubber rods 4 in the middle will contact and work with the material, and the raised spheres 41 will move inward. Retraction is performed by providing a reinforcement rod 5 in the middle of the rail 2, so that when the tooth block 22 rotates, the scraper 51 will scrape off the impurities accumulated in the middle of the tooth block 22. At the same time, there are many protrusions and hardened impurities in the middle of the tooth block 22, which can be pushed and cleaned with the help of the torque between the reinforcement rod 5 and the scraper 51. Two sets of wheels 6 are provided in the middle of the top plate 15, so that when the top plate 15 is pulled out, the wheels 6 will roll in the middle of the vertical plate 17. Two sets of rubber pads 7 are provided in the middle of the workbench 1, so that when the supporting force is lost and it descends, the bottom of the frame plate 13 will directly contact the top of the rubber pad 7, and with the help of the rubber pad 7 made of soft material, the force of the frame plate 13 descending is buffered.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
