Description

Technical Field

[0001] This utility model relates to the field of laser ablation platform technology, specifically to a laser ablation platform with active auxiliary air intake function. Background Technology

[0002] With the development of science and technology, people are increasingly using surface modification techniques to repair damaged parts or improve their surface properties. Laser cladding is an advanced surface modification technology that uses laser irradiation on the surface of a substrate to simultaneously melt and rapidly solidify both the substrate and the cladding material, forming a surface cladding layer with extremely low dilution and a metallurgical bond to the substrate. This technology features rapid heating and cooling rates, easy production of fine-grained structures or new phases that cannot be obtained in equilibrium, high interfacial bonding strength, low heat input, low distortion, and virtually no thermal deformation. It has wide applications in industries such as aerospace, electronics, electrical engineering, and transportation.

[0003] However, when the substrate is made of metal, especially non-ferrous metal, contact with air during laser processing can cause severe oxidation and hydrogenation, requiring protection of areas above a certain temperature. The traditional method of protection is to create a fully enclosed inert gas atmosphere, but this is expensive due to high equipment costs, large gas consumption, and high operating costs. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a laser ablation platform with active auxiliary air intake function, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides a laser ablation platform with active assisted air intake function, including a laser ablation device and an adjustment device disposed on the device. Side plates are fixed to both sides of the laser ablation device, and threaded rods are fixed to the outer sides of the side plates. A cleaning device is sleeved on the outer side of the threaded rods. The cleaning device includes a movable frame, sliders fixed to both sides of the movable frame, and an air box fixed to the outer side of the movable frame. The sliders are fixedly sleeved with the threaded rods, and the bottom end of the air box is connected to an air pipe. The tail end of the air pipe is fixedly engaged with a drive assembly. The bottom end of the laser ablation device is fixedly connected to a base frame, and the bottom end of the base frame is fixed to an external structure via a support frame. The drive assembly includes a connecting plate, a drive motor fixed to the bottom end of the connecting plate, and a bevel gear fixedly connected to the output end of the drive motor. One side of the bevel gear meshes with a side gear, and the middle part of the side gear is fixedly connected to a rotating rod. The middle part of the rotating rod is fixedly connected to a connecting rod, and the bottom end of the connecting rod is fixedly connected to a base plate.

[0008] Furthermore, the two ends of the threaded rod are fixedly connected to the side plate through a screw seat structure, and the slider is a screw support structure, and the slider is engaged and fixed with the threaded rod.

[0009] Furthermore, the front end of the base plate is provided with a locking groove, and the locking groove is fixedly locked to the air pipe, and the bottom end of the air pipe is connected to the nozzle.

[0010] Furthermore, one end of the bevel gear is fixedly connected to the connecting plate via a base frame, and the outer side of the connecting plate is fixedly connected to the air box. A high-pressure air pump structure is installed inside the air box, and the air pipe is kept in communication with the output end of the air pump.

[0011] Furthermore, the bottom frame is flared, wider at the top and narrower at the bottom, and the bottom of the laser ablation device is hollow. There are holes at the bottom of the bottom frame, and the outside of the bottom frame is connected to an external air source through a pipe.

[0012] Furthermore, the bottom end of the adjustment device remains connected and fixed to the laser head, and the adjustment device is fixed between the side plates on both sides.

[0013] Furthermore, a mounting plate is fixed on the side plate, and workpieces are laid between the mounting plates.

[0014] Beneficial effects

[0015] This invention utilizes a cleaning device. The user first places the workpiece on a mounting plate, then adjusts the laser head structure using the adjustment device to position it on the workpiece before laser processing. Before operation, the position (height) of the cleaning device can be manually adjusted. A slider within the cleaning device drives a moving frame structure to slide on both side plates. Because the side plates have threaded rod structures, the moving frame structure can move up and down on the outer side of the side plates, moving the air box-drive assembly and air pipe to the workpiece. The air pipe can be a PE corrugated pipe structure, and its drive assembly structure allows for left and right deflection, increasing the contact area between the airflow and the workpiece. Molten products blown up are limited by the moving frame structure and fall into the bottom frame for collection. Therefore, in actual use, this reduces the burning effect of high-temperature debris generated during laser operation on the workpiece surface, while maintaining a clean work surface and reducing cleaning steps.

[0016] In this device, through the designed drive assembly structure, the user can drive the bottom bevel gear to rotate (horizontally) via the drive motor, which in turn drives the side gear and the rotating rod to rotate (vertically). This causes the connecting rod to rotate on the rotating rod, and finally causes the base plate to deflect to one side. Since the air pipe is fixed to the base plate through a locking groove, the air pipe can be quickly inserted and fixed. At the same time, the nozzle at the bottom can cover the workpiece from all directions, removing molten debris and other particulate matter. Attached Figure Description

The cleaning device 3 includes a moving frame 31, sliders 32 fixed to both sides of the moving frame 31, and an air box 33 fixed to the outer side of the moving frame 31. The sliders 32 are fixedly sleeved with the threaded rod 12, and the bottom end of the air box 33 is connected to an air pipe 35. The tail end of the air pipe 35 is fixedly engaged with a drive assembly 34. The bottom end of the device 1 is fixedly connected to the bottom frame 36, and the bottom end of the bottom frame 36 is fixed to the external structure through the support frame 37. The drive assembly 34 includes a connecting plate 341, a drive motor 342 fixed to the bottom end of the connecting plate 341, and a bevel gear 344 fixedly connected to the output end of the drive motor 342. One side of the bevel gear 344 is meshed with a side gear 346, and the middle part of the side gear 346 is fixedly connected to a rotating rod 345. The middle part of the rotating rod 345 is fixedly connected to a connecting rod 347, and the bottom end of the connecting rod 347 is fixedly connected to the bottom plate 348.

[0025] Both ends of the threaded rod 12 are fixedly connected to the side plate 11 through a screw seat structure, and the slider 32 is a screw support structure, and the slider 32 is engaged and fixed with the threaded rod 12; the front end of the base plate 348 is provided with a locking groove 349, and the locking groove 349 is fixedly locked with the air pipe 35, and the bottom end of the air pipe 35 is connected to the nozzle; in this device, through the provided drive component 34 structure, the user can drive the bevel gear at the bottom through the drive motor 342. Rotation 344 (horizontal direction) drives the side gear 346 and the rotating rod 345 to rotate (vertical direction), thus driving the connecting rod 347 to rotate on the rotating rod 345, and finally driving the base plate 348 to deflect to one side. Since the air pipe 35 and the base plate 348 are fixedly engaged through the locking groove 349, the air pipe 35 can be quickly inserted and fixed. At the same time, the nozzle at the bottom can cover the workpiece 5 in all directions to remove the generated molten debris and other particulate matter.

[0026] One end of the bevel gear 344 is fixedly connected to the connecting plate 341 via the base frame 343. The outer side of the connecting plate 341 is fixedly connected to the air box 33. A high-pressure air pump structure is installed inside the air box 33, and the air pipe 35 is connected to the output end of the air pump. The bottom frame 36 is flared, wider at the top and narrower at the bottom, and the bottom end of the laser ablation device 1 is hollow. Holes are formed at the bottom end of the bottom frame 36, and the outer side of the bottom frame 36 is connected to an external air source via a pipe.

A mounting plate 4 is fixed on the side plate 11, and a workpiece 5 is placed between the mounting plates 4. Using the cleaning device 3, the user first places the workpiece 5 on the mounting plate 4, and then adjusts the structure of the laser head 21 using the adjustment device 2 to perform ablation on the workpiece 5. Position adjustment and laser processing: Before operation, the position (height) of the cleaning device 3 can be manually adjusted. The slider 32 in the cleaning device 3 can drive the moving frame 31 structure to slide on the side plates 11 on both sides. Since the side plate 11 is provided with a threaded rod 12 structure, the moving frame 31 structure can move up and down on the outside of the side plate 11, driving the air box 33-drive component 34 and air pipe 35 to the workpiece 5. The air pipe 35 can be a PE corrugated pipe structure, and can be deflected left and right through the drive component 34 structure to expand the contact area between the airflow and the workpiece 5. The blown molten products can be limited by the moving frame 31 structure and fall into the bottom frame 36 to achieve the collection function. Therefore, in actual use, the burning effect of high temperature debris generated during laser work on the surface of the workpiece 5 can be reduced, while keeping the worktable clean and reducing cleaning steps.
