Description

Technical Field

[0001] The invention relates to the field of laser engraving machines, and more particularly to a multi-station laser engraving machine. Background Art

[0002] A laser engraving machine is a device that uses laser technology for engraving and cutting. It is widely used in different industries and fields. A multi-station laser engraving machine is a device with multiple laser engraving or cutting heads that can process multiple workpieces at the same time. This design greatly improves production efficiency and processing capabilities and is suitable for large-scale production and batch processing.

[0003] Laser engraving is usually divided into short-distance engraving and long-distance engraving. In the short-distance engraving process, the laser beam is more concentrated and can transfer energy to the material surface more effectively, thereby causing stronger combustion and gasification. The high-intensity heat energy will cause the material to decompose and evaporate rapidly, usually producing a large amount of dust and smoke. These dust and smoke will form a film on the surface of the material, making the engraved pattern blurred and affecting the beauty and clarity of the finished product. At the same time, the particles in the smoke will cause the laser beam to reflect and scatter, which will not only reduce the concentration of the laser, but also affect the engraving depth and accuracy, thereby resulting in a decrease in engraving quality.

[0034] The air blowing assembly includes an L-shaped top seat 11 arranged above the surrounding frame 2, the L-shaped top seat 11 is fixedly installed with the top of the base 1, a cylinder 12 is fixedly installed on the top of the L-shaped top seat 11, a gas storage frame 13 is fixedly installed on the output end of the cylinder 12, a circular plate 14 is evenly fixedly installed on the bottom of the gas storage frame 13, a laser engraving machine body 15 is fixedly installed on the bottom of each group of circular plates 14, each group of laser engraving machine bodies 15 is located directly above the adjacent surrounding frame 2, and a circular plate 14 is arranged on the outer side of each group of laser engraving machine bodies 15. Tube 16, each group of circular tubes 16 is fixedly installed with the bottom of the adjacent circular plate 14, a vertical tube 17 is fixedly installed on one side of the top of the L-shaped top seat 11, and a fan 20 is fixedly installed in the inner cavity of the vertical tube 17, and a telescopic tube 18 is fixedly installed between the L-shaped top seat 11 and the air storage frame 13, and the two ends of the telescopic tube 18 are respectively connected with the vertical tube 17 and the inner cavity of the air storage frame 13, and each group of circular plates 14 is evenly provided with through holes 19, and the two ends of each group of through holes 19 are respectively connected with the air storage frame 13 and the inner cavity of the adjacent circular tube 16.

[0035] The inner cavity of each group of surrounding frames 2 is provided with a placement seat 22, and a vertical rod 23 is fixedly installed at the bottom of each group of placement seats 22. Each group of vertical rods 23 is slidably installed with the adjacent surrounding frames 2 and the horizontal tube 5. A telescopic spring 24 is fixedly installed between each group of placement seats 22 and the bottom wall of the inner cavity of the adjacent surrounding frame 2. Two groups of clamps 25 are slidably installed on the top of each group of placement seats 22. A connecting plate 26 is rotatably installed on one side of each group of clamps 25 close to the inner cavity wall of the adjacent surrounding frame 2, and the other end of each group of connecting plates 26 is rotatably installed with the inner cavity wall of the adjacent surrounding frame 2.

[0036] First, place the plate to be engraved on the top of the placement seat 22. Under the weight of the plate itself, the placement seat 22 will be pressed to move downward. The placement seat 22 moves downward and slides on the surrounding frame 2 and the cross tube 5 through the vertical rod 23. The placement seat 22 will squeeze the telescopic spring 24 while moving downward. At the same time, through the setting of the connecting plate 26, when the placement seat 22 moves downward, the end of the connecting plate 26 close to the clamping plate 25 will push the clamping plate 25 to slide on the top of the placement seat 22. At this time, the two adjacent groups of clamping plates 25 can move close to each other on the top of the placement seat 22, and the two groups of clamping plates 25 can clamp and fix the plate on the top of the placement seat 22, which plays the role of automatic clamping, which can effectively improve the stability of the engraving, avoid the problem of disordered engraving patterns caused by the deviation of the plate during the engraving process, and effectively improve the aesthetics of the engraving, thereby effectively improving the quality of the engraving.

[0037] After the plate to be engraved is automatically fixed on the top of the placement seat 22, the cylinder 12 is turned on. The output end of the cylinder 12 extends to push the gas storage frame 13 to move downward, which will adaptively stretch the telescopic tube 18. While the gas storage frame 13 moves downward, it will drive the laser engraving machine body 15 to move downward synchronously through the circular plate 14. Then, after the laser engraving machine body 15 is adjusted to a suitable distance above the plate to be engraved, the cylinder 12 is closed and the fan 4 is turned on. When the fan 4 works, it will suck air from the upper part of the inner cavity of the fixed tube 3. The fan 4 sucks air from the inner cavity of the transverse tube 5 through the port 7. The inner cavity of the transverse tube 5 sucks air from the inner cavity of the surrounding frame 2 through the suction hole 6, so that the fan 4 can suck the gas in the surrounding frame 2 and discharge it into the inner cavity of the collecting frame 8 through the fixed tube 3. Then, the laser engraving machine body 15 is turned on. The laser engraving machine body 15 will The material is engraved, and multi-station processing is realized by setting multiple groups of placement seats 22 and the laser engraving machine body 15, which can effectively improve the work efficiency. Due to the short-distance engraving process of the laser engraving machine body 15, a large amount of dust and smoke will be generated on the surface of the plate being engraved. Through the suction force generated by the fan 4 around the inner cavity of the frame 2, these dust and smoke will be directly sucked into the fixed pipe 3 by the fan 4 and discharged into the collection frame 8, and then the smoke and dust will be filtered through the filter net 9, and the dust will be filtered into the inner cavity of the collection frame 8 for collection, and the harmful gas or irritating odor in the smoke will be filtered and purified by the activated carbon 10 and then discharged, which can avoid the situation that the engraved pattern is blurred due to the appearance of dust and smoke, and can effectively improve the beauty and clarity of the finished product, and at the same time can improve the concentration of the laser and improve the engraving effect, so as to effectively improve the quality of engraving;

[0038] After adjusting the position of the laser engraving machine body 15 through the cylinder 12, the fan 20 is turned on. The fan 20 absorbs external air through the vertical pipe 17 and then discharges it into the inner cavity of the air storage frame 13 through the telescopic pipe 18. The gas in the inner cavity of the air storage frame 13 is discharged into the inner cavity of the circular tube 16 through the through hole 19. The gas discharged into the inner cavity of the circular tube 16 is blown downward, so that the dust and smoke generated by the engraving on the plate can be quickly blown away in the inner cavity of the surrounding frame 2, reducing the residence time of the dust on the plate, and preventing the dust and smoke from affecting the engraving of the laser engraving machine body 15. The blowing can quickly blow the smoke and dust generated during the engraving process away from the surface of the plate, preventing these substances from being blown away during the working process. At the same time, by removing the smoke, the operator can observe the engraving process more clearly, so as to make more precise adjustments. At the same time, with the cooperation of the fan 4 to the suction in the surrounding frame 2, the efficiency of removing dust and smoke in the inner cavity of the surrounding frame 2 can be effectively improved, so as to effectively improve the engraving effect. At the same time, under the action of the round tube 16 blowing, the gas will flow downward along the outer wall of the laser engraving machine body 15, so as to realize the cooling of the laser engraving machine body 15 itself, reduce the heat accumulation inside the equipment and the optical components, and extend the service life of the equipment. At the same time, it can prevent the optical components such as lenses and lenses from being contaminated by smoke and dust, so as to maintain the output efficiency of the laser.

[0039] like Figures 4 to 6 As shown, a rotating rod 28 is rotatably installed in the inner cavity of each group of horizontal tubes 5, a fan blade 29 is fixedly installed on the side of each group of rotating rods 28 away from the fixed tube 3, an elastic rod 30 is evenly fixedly installed on the rod wall of each group of rotating rods 28, and an impact ball 31 is fixedly installed on the other end of each group of elastic rods 30.

[0040] A groove 32 adapted to the impact ball 31 is provided on the inner wall of each group of transverse tubes 5 , and each group of elastic rods 30 is in a bent state in the initial state.

[0041] Circular plates 33 are provided on both sides of each group of impact balls 31 in the vertical direction, and each group of circular plates 33 is fixedly mounted on the inner cavity wall of the adjacent transverse tube 5 .

[0042] When the fan 4 is working to extract the gas in the surrounding frame 2, the gas in the surrounding frame 2 will enter the inner cavity of the horizontal tube 5 through the suction hole 6, and then enter the fixed tube 3 through the opening 7. When the gas flows through the horizontal tube 5, the fan blades 29 will be driven to rotate. When the fan blades 29 rotate, the rotating rod 28 will be driven to rotate. When the rotating rod 28 rotates, the impact ball 31 is driven to perform synchronous circular motion through the elastic rod 30. In the initial state, the elastic rod 30 is in a bent state, so that the impact ball 31 can be tightly attached to the inner cavity of the groove 32. When the rotating rod 28 drives the impact ball 31 to move in a circle through the elastic rod 30, the elastic rod 30 will be bent again when the impact ball 31 moves out of the inner cavity of the groove 32. At this time, the rotation of the rotating rod 28 will drive the elastic rod 30 to drive the impact ball 31 to move in a circle. The dynamic impact ball 31 moves on the inner wall of the horizontal tube 5. When the impact ball 31 moves to the position of the next group of grooves 32, under the action of the elastic rod 30, the elastic rod 30 restores the initial state to push the impact ball 31 into the inner cavity of the groove 32 and realizes the impact. At this time, during the rotation of the rotating rod 28, the elastic rod 30 can drive the impact ball 31 to reciprocate and impact the inner cavity of the groove 32 and vibrate the horizontal tube 5. The shock wave will be transmitted to the surrounding frame 2, which can vibrate the engraved plate and reduce the adhesion of residual dust on the plate during the engraving process. At the same time, with the cooperation of the round tube 16 blowing, the dust removal effect on the engraved plate can be effectively improved, and the plate can be kept clean during the engraving process, thereby effectively improving the engraving effect.

[0043] By disposing the annular plates 33 on both sides of the impact ball 31, the process of the elastic rod 30 driving the impact ball 31 to move in a circular motion can be guided, playing a role of limiting guidance, and avoiding the impact ball 31 from deflecting.

[0044] like Figures 1 to 5 As shown, a second filter screen 21 is disposed above the second fan 20 , and the second filter screen 21 is fixedly mounted to the inner cavity wall of the vertical pipe 17 .

[0045] Each group of clamping plates 25 is provided with anti-slip patterns 27 on one side away from the inner wall of the adjacent surrounding frame 2 .

[0046] The number of the surrounding frames 2 is the same as the number of the laser engraving machine bodies 15 .

[0047] Each group of vertical rods 23 is sealed and slidably mounted with the adjacent surrounding frame 2 and the horizontal tube 5 , and each group of laser engraving machine bodies 15 is located directly above the adjacent placement seat 22 .

[0048] By setting the filter mesh 21, when the fan 20 is working to suck the outside air into the vertical pipe 17, the impurities in the gas can be filtered, and when the clamping plate 25 automatically clamps and fixes the plate to be engraved on the top of the placement seat 22, the anti-slip texture 27 can be set to increase the friction between the clamping plate 25 and the plate, thereby improving the stability of the clamping plate 25 on the plate.

[0049] Working principle: first, place the plate to be engraved on the top of the placement seat 22. Under the gravity of the plate itself, the placement seat 22 will be pressed downward, so that the clamping plate 25 can automatically clamp and fix the plate. Turn on the cylinder 12. The extension of the output end of the cylinder 12 will push the laser engraving machine body 15 to move downward. After adjusting the position of the laser engraving machine body 15, turn on the laser engraving machine body 15. The laser engraving machine body 15 will engrave the plate on the top of the placement seat 22. At the same time, turn on the fan 2 20 and the fan 1 4. The fan 2 20 will absorb the external gas and blow it downward through the circular tube 16. The circular tube 16 will blow the dust and smoke generated during the plate engraving process into the surrounding frame 2. The fan 1 4 will absorb the dust and smoke and discharge them into the collection frame 8. The circular tube 16 is in While blowing, the laser engraving machine body 15 will be cooled and dissipated. When the fan 4 absorbs the gas in the surrounding frame 2, the gas will flow through the inner cavity of the horizontal tube 5. The gas will drive the fan blades 29 to rotate while flowing. At this time, the rotating rod 28 will drive the impact ball 31 to perform a circular motion in the inner cavity of the horizontal tube 5 through the elastic rod 30. Through the setting of the groove 32, the impact ball 31 can reciprocately impact the inner cavity of the groove 32 during the circular motion. The horizontal tube 5 will vibrate, and the shock wave will also be transmitted to the surrounding frame 2, which can reduce the adhesion of the residual dust on the plate, so that the circular tube 16 can reduce the dust blown away in the inner cavity of the surrounding frame 2. After the plate is engraved, the laser engraving machine body 15 is controlled by the cylinder 12 to move upward away from the surrounding frame 2, and then the placement seat 22 is pushed to move upward to remove the engraved plate.

[0050] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
