Description

Technical Field

[0001] The invention relates to the technical field of laser engraving, in particular to a stable micro-circular tube laser engraving machine. Background Art

[0002] Metal round tubes, including but not limited to stainless steel round tubes, carbon steel tubes, aluminum tubes, etc., are widely used in various fields. In order to meet the processing needs of round tubes in various fields, such as marking, personalized customization, surface treatment, etc., it is often necessary to engrave metal round tubes. Laser engraving is an existing mature technology. It uses the monochromaticity and high brightness characteristics of lasers to evaporate and melt the surface of the material through the laser beam to achieve fine engraving.

[0003] When an existing laser engraving machine engraves a round tube, the two ends of the round tube are clamped and adaptively rotated according to the engraving requirements. The laser emitted by the laser head acts on the surface of the round tube to achieve engraving of the round tube. It is well known that in order to ensure the accuracy and effect of engraving, the light spot of the laser head should be the smallest so that the energy gathered by the laser is the highest. However, in the actual engraving of round tubes, it is found that the processed round tubes are often of different sizes. It is often necessary to engrave round tubes of different thicknesses according to production requirements. Every time the size of the round tube is changed, the hand wheel must be adjusted to readjust the focal length so that the light spot is in a suitable state, which brings inconvenience.

[0004] To this end, we propose a stable micro-circular tube laser engraving machine. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] See also Figures 1 to 10 The present invention provides a technical solution: a stable micro-circular tube laser engraving machine, comprising: a workbench 1, a moving component 2 and a laser head 3, wherein the moving component 2 is installed on the workbench 1, and the laser head 3 is installed on the moving component 2, and the moving component 2 can drive the laser head 3 to move up and down and left and right.

[0040] The installation of the moving component 2 is achieved by a mounting frame 8 fixed on the workbench 1, and the moving component 2 and the mounting frame 8 are slidably connected.

[0041] A support member 4 is installed on the upper surface of the workbench 1. The support member 4 is used to support the round tube, and a clamp 1 5 and a clamp 2 6 are respectively arranged on the left and right sides of the support member 4. In this embodiment, the clamp 1 5 is a rotatable three-jaw chuck, and the clamp 2 6 is a mounting seat 11 installed on the workbench 1. A round tube is fixed to the end of the mounting seat 11, and a plurality of groups of movable rods 13 are equidistantly slidably installed on the ring 12. An arc plate 14 is fixed to one end of the movable rod 13, and a plurality of balls 15 are rotatably installed in the arc plate 14. A limit rod 16 is fixed to the other end of the movable rod 13, and a first spring 17 is sleeved on the outer side of the movable rod 13.

[0042] At the same time, a driving assembly 7 is installed at the bottom of the clamp 1 5 and the clamp 2 6, and the driving assembly 7 can drive the clamp 1 5 and the clamp 2 6 to move closer to or away from each other, that is, a motor 18 is fixed on one side of the workbench 1, and a bidirectional screw 19 is fixed at the end of the motor 18, and the bidirectional screw 19 is threadedly connected with the clamp 1 5 and the clamp 2 6 respectively.

[0043] Through the above technical solution, when engraving, the round tube is placed on the support 4, and the motor 18 is driven, and the motor 18 drives the bidirectional screw 19 to rotate. When the two-way screw 19 rotates, the clamp 1 5 and the clamp 2 6 approach each other. For the clamp 1 5, when the end of the circular tube enters the interior of the clamp 1 5, the three-jaw chuck clamps one end of the circular tube. After clamping, the driving component 7 continues to act. When the clamp 1 5 and the clamp 2 6 approach each other, the circular tube with one end fixed squeezes the arc plate 14 at the other end, so that the movable rod 13 on the arc plate 14 slides to the outside of the ring 12 and compresses the first spring 17 until the other end of the circular tube is clamped in the plurality of arc plates 14. When engraving is performed, the three-jaw chuck rotates to drive the clamped circular tube to rotate, and the other end of the circular tube can be rotated by the ball 15 on the inner side of the arc plate 14. After the engraving is completed, the driving component 7 reverses and drives the clamp 1 5 and the clamp 2 6 to move away from each other. During the movement, one end of the circular tube is first separated from the clamp 2 6. When the circular tube is separated from the clamp 2 6, the three-jaw chuck is released, and the circular tube falls back on the support 4.

[0044] At the same time, when the end of the round tube enters the inner side of the arc plate 14, the thicker the round tube is, the stronger the squeezing force of the round tube on the arc plate 14 is, and the larger the moving distance of the movable rod 13 and the limit rod 16 is, and vice versa. Therefore, while the clamp 2 6 clamps the round tube, the thickness of the round tube can also be judged according to the movement change of the movable rod 13 and the limit rod 16.

[0045] A fine-tuning mechanism 9 is installed between the mounting frame 8 and the moving assembly 2. The fine-tuning mechanism 9 can adjust the height of the moving assembly 2. Specifically, the moving assembly 2 includes a fixed plate 22 fixed to the inner side of the mounting frame 8 and a movable plate 21 slidably installed on the inner side of the mounting frame 8. An adjusting screw 20 is threadedly connected to the inner side of the movable plate 21. The top of the adjusting screw 20 is rotatably installed on the fixed plate 22 and the bottom of the adjusting screw 20 is rotatably installed on the bottom of the mounting frame 8. Push plates 23 are fixed on both sides of the movable plate 21. The top of the push plate 23 is against the bottom of the mounting frame 8.

[0046] Therefore, through the above technical solution, the bottom of the mobile component 2 in the fixed state is supported by the push plate 23. When the height of the mobile component 2 is fine-tuned, the adjusting screw 20 only needs to be rotated. When the adjusting screw 20 is rotated, it drives the movable plate 21 to slide on the inner side of the mounting frame 8, but when the movable plate 21 slides, it will simultaneously drive the push plate 23 to slide in the fixed plate 22. When the push plate 23 slides upward, it will drive the entire mobile component 2 to move upward. When the push plate 23 moves downward, the mobile component 2 will move downward under the action of its own gravity, thereby achieving fine-tuning of the height of the mobile component 2.

[0047] It should be added that telescopic rods 53 are installed on both sides of the movable plate 21. Springs are installed in the telescopic rods 53. The telescopic rods 53 can move with the movement of the movable plate 21. At the same time, when the movable plate 21 is stationary, the telescopic rods 53 can also provide a certain supporting force for the movable plate 21, which can reduce the load of the movable component 2 falling on the movable plate 21, ensure that the connection between the movable plate 21 and the adjusting screw 20 maintains a good working condition, is not easy to be damaged, and also improves the stability of the installation of the movable component 2.

[0048] In this embodiment, the arc plate 14, the movable rod 13 and the limit rod 16 on the circular ring 12 are all set to four, which are respectively distributed at the upper, lower, left and right positions of the circular ring 12. A transmission member 10 is installed at the end of the left limit rod 16, and the transmission member 10 can drive the fine adjustment mechanism 9 to move. Specifically, a roller 24 is fixed at the end of the left limit rod 16, and the end of the roller 24 is abutted with a rack 25 with an inclined surface. The rack 25 is slidably installed on the side of the moving component 2, and a third spring 54 is fixed at the rear end of the rack 25. A gear 26 is meshed on one side of the rack 25, and a pulley 27 is coaxially fixed at the bottom of the gear 26, and a pulley 28 is coaxially fixed on the adjusting screw 20. A transmission belt 29 is installed between the pulley 27 and the pulley 28, and a through hole 52 is opened on the push plate 23 close to the side of the gear 26, so that the transmission belt 29 can be connected with the inner adjusting screw 20 through the through hole 52.

[0049] Through the above technical scheme, when the clamp 2 6 clamps the round tube, since the moving distance of the limit rod 16 can be changed according to the thickness of the round tube, when the clamp 2 6 and the clamp 1 5 are close to each other, the roller 24 located on the left limit rod 16 squeezes the rack 1 25 with the inclined surface, so that the rack 1 25 slides. The greater the moving distance of the limit rod 16, the greater the moving distance of the rack 1 25. When the rack 1 25 moves, it meshes with the gear 1 26, driving the gear 1 26 to rotate. When the gear 1 26 rotates, it drives the pulley 1 27 to rotate. When the pulley 1 27 rotates, it drives the pulley 2 28 to rotate through the transmission belt 29, thereby realizing the rotation of the adjusting screw 20. When the adjusting screw 20 rotates, the height of the moving component 2 can be adjusted. The height change of the moving component 2 will also synchronously drive the height of the laser head 3 to change.

[0050] For example, when the engraving of a thin round tube turns into the engraving of a thick round tube, the focal length between the laser head 3 and the round tube will decrease, and the light spot acting on the surface of the round tube will increase. However, when the clamp 2 6 clamps the thick round tube, the displacement of the limit rod 16 is adjusted to rotate the screw 20, so that the height of the moving component 2 and the laser head 3 increases. When the height of the laser head 3 increases, the focal length between the laser head 3 and the round tube increases accordingly, thereby compensating for the focal length error caused by the change in the size of the round tube, so that the round tube can be processed more precisely, and there is no need for manual adjustment by the user. It is suitable for the processing needs of different round tubes and can effectively improve the processing efficiency of the round tube.

[0051] After the round tube is engraved, the clamp 1 5 and the clamp 2 6 are reset, and the round tube is separated from the clamp 2 6 after the reset. At this time, the movable rod 13 and the limit rod 16 are reset under the action of the first spring 17, and the rack 1 25 is also reset under the action of the third spring 54. During the reset process of the rack 1 25, the moving assembly 2 is readjusted so that the moving assembly 2 is restored to the default height;

[0052] It should be noted that in this embodiment, the end of the limit rod 16 and the roller 24 drive the rack 25 to slide by squeezing the roller 24 and the rack 25 with the inclined surface. Similarly, the inclined surface and the roller 24 can be squeezed to make the roller 24 slide, and the rack 25 can be driven to slide by the sliding of the roller 24.

[0053] Embodiment 2

[0054] In this embodiment, the support member 4 is composed of two symmetrically arranged arc-shaped movable seats 35, and one movable seat 35 is slidably connected to the workbench 1, while the other movable seat 35 is fixedly connected to the workbench 1. A pushing cylinder 36 is fixed on one side of the slidable movable seat 35. At the same time, a feeding port 37 is opened on the upper surface of the workbench 1, and an inclined feeding chute 38 is arranged at the bottom of the feeding port 37. Therefore, after the round tube is engraved, the pushing cylinder 36 drives the slidable movable seat 35 to separate from the fixed movable seat 35, and the round tube located on the support member 4 will enter the feeding chute 38 through the feeding port 37 at the bottom, thereby realizing automatic feeding of the round tube.

[0055] The rear baffle 33 is located behind the discharge port, and the front baffle 33 is fixed to the rear baffle 33. The round tube is stored in the storage hopper 32. The distance between the front baffle 33 and the rear baffle 33 is the same as the diameter of the round tube. When discharging, the pushing member 34 drives the front baffle 33 and the rear baffle 33 to move upward. When the front baffle 33 moves upward, the discharge port is opened, and the rear baffle 33 enters the storage hopper 32 when moving upward. After entering the storage hopper 32, the rear baffle 33 blocks the round tube at the rear, so that only one round tube can be discharged at a time. After the round tube is discharged, the pushing member 34 drives the front baffle 33 and the rear baffle 33 to move downward synchronously. At this time, the rear baffle 33 is separated from the storage hopper 32, and the round tube located at the rear baffle 33 can be supplemented to the discharge port.

[0056] At the same time, in this embodiment, the bidirectional screw 19 in the driving component 7 is set to two sections, and the two sections of the bidirectional screw 19 are respectively threadedly connected to the clamp 1 5 and the clamp 2 6. At the same time, the driving component 7 also includes a transmission rod 30 and a belt transmission component 31. The transmission rod 30 rotates on one side of the bidirectional screw 19, and the belt transmission component 31 is installed between the end of the bidirectional screw 19 and the end of the transmission rod 30. Therefore, when the motor 18 rotates, it drives the bidirectional screw 19 on one side to rotate. When the bidirectional screw 19 rotates, the transmission rod 30 is driven to rotate through the belt transmission component 31. When the transmission rod 30 rotates, it drives the bidirectional screw 19 on the other side to rotate, thereby realizing the simultaneous rotation of the two sections of the bidirectional screw 19, which provides an installation space for the unloading chute 38, so that the fallen round pipe can fall on the unloading chute 38 instead of falling on the bidirectional screw 19.

[0057] At the same time, a storage hopper 32 is also installed at the front end of the mobile component 2. Two baffles 33 are slidably installed at the bottom of the storage hopper 32. The two baffles 33 are arranged one in front and one behind. A pusher 34 is installed on the top of the baffle 33. The pusher 34 can also be realized by a cylinder.

[0058] Through the above technical solution, the storage hopper 32 is used to store unprocessed round tubes. When the round tubes need to be loaded, the pusher 34 drives the two baffles 33 to move upward. The baffle 33 at the front end opens the discharge port of the storage hopper 32 when moving upward, so that the round tubes in the storage hopper 32 slide onto the support 4, and the baffle 33 at the rear end blocks the round tubes at the rear during the upward movement, so as to avoid multiple round tubes sliding out of the discharge port at the same time when the discharge port is opened, so as to ensure that only one round tube is transported each time the material is loaded.

[0059] Therefore, in actual use, automatic loading and unloading of round tubes can be realized, which can further improve the processing efficiency of round tubes. There is no need for operators to stay around the engraving machine all the time, which can reduce the absorption of smoke by users during the engraving process and ensure the user's physical safety.

[0060] Embodiment 3

[0061] A plurality of suction heads 39 are equidistantly mounted on a movable seat 35 fixed on the workbench 1, a pipe 40 is mounted on the other end of the suction head 39, an air pump 41 is mounted on the other end of the pipe 40, and a filter structure is mounted on the pipe 40, the filter structure can filter the adsorbed smoke, and the air pump 41 is fixed on the bottom of the workbench 1;

[0062] Furthermore, a side plate 45 is fixed on the top of the movable seat 35 fixed on the workbench 1, a mounting plate 46 is fixed on the suction head 39, a vertical rod 47 is rotatably mounted on the end of the mounting plate 46, a connecting rod 48 is rotatably mounted on the bottom of the mounting plate 46, the other end of the connecting rod 48 is rotatably mounted on the side plate 45, a sleeve 49 is slidably mounted on the bottom of the vertical rod 47, a connecting pipe 50 is connected to the bottom of the sleeve 49, the other end of the connecting pipe 50 is mounted on the pipeline 40, a second spring 51 is sleeved on the bottom of the vertical rod 47, and the second spring 51 is located in the sleeve 49.

[0063] Through the above technical solution, when negative pressure is generated in the pipeline 40, the negative pressure will also enter the sleeve 49 through the connecting pipe 50, so that negative pressure is also generated in the sleeve 49. When negative pressure is generated in the sleeve 49, the adsorption vertical rod 47 moves downward, and at the same time drives the second spring 51 to stretch. When the vertical rod 47 moves downward, it will drive the angle of the mounting plate 46 and the connecting rod 48 to change, so that the angle of the suction head 39 is adjusted upward, thereby changing the angle of the suction head 39. Moreover, when the size of the circular tube is larger, the negative pressure in the sleeve 49 is greater, and the angle of the suction head 39 is greater. Conversely, the position of the suction head 39 can be adaptively adjusted according to the size of the circular tube to ensure that the position of the suction head 39 always remains at the engraved position, further improving the adsorption effect of the flue gas.
