Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for metal parts, specifically to a surface treatment device for metal parts. Background Technology

[0002] In the surface treatment of metal parts, rust removal is crucial to ensuring the effective implementation of subsequent surface treatments. Currently, rust removal is typically accomplished using laser rust removal machines. The working principle involves using a high-energy laser beam to irradiate the metal surface, causing rust and oxides to rapidly expand and vaporize, thus removing the rust. However, based on this principle, laser rust removal machines still have certain limitations. Because the surface of the parts experiences high heat during laser rust removal, after the surface is treated, oxidation occurs rapidly in the air due to the high temperature, forming a new oxide layer. This is clearly unsuitable for parts with special surface treatment requirements or where further processing (such as plating) is needed after edge treatment. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a surface treatment device for metal parts.

[0004] The technical solution of this utility model is as follows:

[0005] A surface treatment device for metal parts includes a laser cleaning machine, which can clean rust from the surface of the parts.

[0006] As the core technical concept of this utility model, the processing equipment (the aforementioned surface treatment equipment for metal parts) also includes a sealed box and a multi-axis motion mechanism inside it. The laser cleaning machine is connected to the multi-axis motion mechanism and can be moved by the multi-axis motion mechanism. Preferably, the multi-axis motion mechanism is a three-axis moving mechanism. The laser cleaning machine is configured to move along the x-axis, y-axis, and z-axis under the drive of the multi-axis motion mechanism to increase the applicability of the processing equipment and ensure the treatment effect of the part surface. A liquid nitrogen spraying mechanism is also provided on one side of the laser cleaning machine, which is configured to spray liquid nitrogen onto the surface of the part cleaned by the laser cleaning machine. Based on the above structure, by setting up a sealed box, the oxygen concentration in the surface treatment environment of the part can be reduced, thereby reducing the possibility of the part surface overheating and reacting with oxygen to form an oxide layer. At the same time, after the laser cleaning machine sweeps across the surface of the part, liquid nitrogen can be quickly sprayed onto the cleaned part surface by the liquid nitrogen spraying mechanism to quickly reduce the surface temperature of the part, further reducing the possibility of the part reacting with oxygen due to surface overheating to form an oxide layer, and ultimately ensuring the treatment effect of the processing equipment.

[0007] As described above, in a surface treatment device for metal parts, the laser irradiation head of the laser cleaning machine faces downward, and the liquid nitrogen spraying mechanism includes a liquid nitrogen bottle and a nozzle connected thereto. In a preferred embodiment, the nozzle orifice is tilted and points downward and to the rear side of the rust removal direction of the laser cleaning machine to prevent interference between the liquid nitrogen spraying and rust removal work, thus ensuring the rust removal effect of the laser cleaning machine.

[0008] As a further preferred embodiment, the horizontal plane where the nozzle is located is above the horizontal plane where the laser irradiation head is located, to prevent the nozzle setting from affecting the movement of the laser cleaning machine driven by the multi-axis motion mechanism, and to ensure that the rust removal work on the surface of the parts can be carried out smoothly.

[0009] Preferably, in order to ensure the cooling effect of liquid nitrogen spraying while further ensuring the rust removal effect of the laser cleaning machine on the surface of the parts, the horizontal distance between the nozzle and the laser irradiation head is 10-17cm.

[0010] To ensure the service life of the nozzle, the nozzle is made of copper.

[0011] As described above, the surface treatment equipment for metal parts has a switch door on one side of the sealed box, which makes it easier to place the parts inside the sealed box. The outer side of the sealed box is equipped with an oxygen removal mechanism to ensure that the laser rust removal work can be carried out in a low oxygen concentration environment, further reducing the possibility of the overheated part surface reacting with oxygen.

[0012] Regarding the structure of the oxygen removal mechanism, it employs a vacuum pump or a protective gas filling machine.

[0013] As described above, in order to facilitate real-time monitoring of the rust removal process on the surface of the parts, the sealed box is made of transparent or semi-transparent glass or acrylic material.

[0014] The beneficial effects of this utility model are as follows: This utility model is a surface treatment equipment for metal parts. The laser cleaning machine can move along the x-axis, y-axis, and z-axis under the drive of a multi-axis motion mechanism to increase the applicability of the treatment equipment and ensure the treatment effect of the parts surface. By setting a sealed box, the oxygen concentration in the surface treatment environment of the parts can be reduced, thereby reducing the possibility of the parts surface overheating and reacting with oxygen to form an oxide layer. After the laser cleaning machine sweeps across the surface of the parts, liquid nitrogen can be quickly sprayed onto the cleaned parts surface through a liquid nitrogen spraying mechanism to quickly reduce the surface temperature of the parts, further reducing the possibility of the parts overheating and reacting with oxygen to form an oxide layer, and ultimately ensuring the treatment effect of the equipment.

[0022] Example

[0023] This embodiment provides a surface treatment device for metal parts; see [link / reference] Figure 1 The equipment includes a laser cleaning machine 4, which is a laser rust removal machine. Its structure will not be described in detail here. The laser cleaning machine 4 can complete the cleaning of rust on the surface of parts. The structure of the processing equipment (the above-mentioned surface treatment equipment for metal parts) will be described in detail below with reference to the accompanying drawings.

[0024] In this embodiment, as one of the core technical concepts, the processing equipment includes a bottom box 1 and a sealed box 2 on its upper side. The sealed box 2 is also provided with a multi-axis motion mechanism 3. The laser cleaning machine 4 is connected to the multi-axis motion mechanism 3 and can be moved by the multi-axis motion mechanism 3.

[0025] Specifically, the bottom of the sealed box 2 is provided with a fixed platform for placing parts. The multi-axis motion mechanism 3 is preferably a three-axis moving mechanism, which includes two Z-axis crossbeams located on the left and right sides of the upper part of the sealed box 2. The Z-axis crossbeams are arranged in the front-to-back direction, and an X-axis crossbeam arranged in the left-to-right direction is connected between the two Z-axis crossbeams. One end of each Z-axis crossbeam is also provided with a Z-axis motor, which is configured to drive the X-axis crossbeam to move along the Z-axis direction. The multi-axis motion mechanism 3 also includes a mounting base slidably disposed on the X-axis crossbeam. One end of the X-axis crossbeam is also provided with an X-axis motor, which is configured to drive the mounting base to move along the X-axis direction. The multi-axis motion mechanism 3 also includes a vertically arranged... The upper end of the telescopic cylinder is fixed to the mounting base. The laser cleaning machine 4 is located at the lower end of the telescopic cylinder and can move along the y-axis under the drive of the telescopic cylinder. Finally, the laser cleaning machine 4 can move along the x-axis, y-axis and z-axis under the drive of the multi-axis motion mechanism 3. The laser irradiation head of the laser cleaning machine 4 faces downward. The surface treatment of the parts on the fixed table can be completed by the movement of the laser processing machine, which increases the applicability of the processing equipment and ensures the surface treatment effect of the parts. At the same time, by setting the sealed box 2, the oxygen concentration of the surface treatment environment of the parts can be reduced, thereby reducing the possibility of the surface of the parts overheating and reacting with oxygen to form an oxide layer, and ensuring the processing effect of the processing equipment.

[0026] As a preferred embodiment, the sealed box 2 is provided with a switch door on one side, so that the parts can be placed more conveniently on the fixed platform inside the sealed box 2. The sealed box 2 is provided with an oxygen removal mechanism on the outside to ensure that the laser rust removal work can be carried out in a low oxygen concentration environment, further reducing the possibility of the overheated parts surface reacting with oxygen.

[0027] Regarding the structure of the oxygen venting mechanism, it employs a vacuum pump or a protective gas filling machine. Specifically, the sealed box 2 has openings on its left and right opposite sides of the box wall, with the two openings located near the upper and lower ends of the sealed box 2, respectively. In one embodiment, when the oxygen venting mechanism is a vacuum pump, it is connected to the opening near the upper end of the sealed box 2, while the other opening is closed. In another embodiment, when the oxygen venting mechanism is a protective gas filling machine, it is connected to the opening near the lower end of the sealed box 2, while the other opening is open. The protective gas can be nitrogen, carbon dioxide, or other inert gases.

[0028] As a further preferred option, to facilitate real-time monitoring of the rust removal process on the parts' surface, the sealing box 2 is made of transparent or semi-transparent glass or acrylic material.

[0029] In this embodiment, combined with Figure 2As another core technical concept of this embodiment, the processing equipment also includes a liquid nitrogen spraying mechanism 5 located on one side of the laser cleaning machine 4. It is configured to spray liquid nitrogen onto the surface of the parts cleaned by the laser cleaning machine 4. Based on the above structure, after the laser cleaning machine 4 sweeps across the surface of the parts, it can quickly spray liquid nitrogen onto the cleaned surface of the parts through the liquid nitrogen spraying mechanism 5 to quickly reduce the surface temperature of the parts, further reducing the possibility of the parts reacting with oxygen due to overheating and forming an oxide layer, and ultimately ensuring the processing effect of the processing equipment.

[0030] Specifically, the liquid nitrogen spraying mechanism 5 includes a liquid nitrogen bottle 51 fixedly connected to the lower end of the telescopic cylinder and a nozzle 52 located on one side of the liquid nitrogen bottle 51 and communicating with it. In a preferred embodiment, the nozzle 52 is inclined to the rear and lower side of the laser cleaning machine 4 in the direction of rust removal. Specifically, the nozzle 52 has a vertically arranged tubular structure, with its upper end communicating with the liquid nitrogen bottle 51 and its lower end being the spray nozzle. It is curved in an arc towards the rear and lower side of the laser cleaning machine 4 in the direction of rust removal to prevent the liquid nitrogen spraying work from interfering with the rust removal work and to ensure the rust removal effect of the laser cleaning machine 4.

[0031] As a further preferred embodiment, the horizontal plane where the nozzle is located is above the horizontal plane where the laser irradiation head is located, to prevent the setting of the nozzle 52 from affecting the movement of the laser cleaning machine 4 driven by the multi-axis motion mechanism 3, and to ensure that the rust removal work on the surface of the parts can be carried out smoothly.

[0032] Furthermore, to ensure the cooling effect of liquid nitrogen spraying while further ensuring the rust removal effect of the laser cleaning machine 4 on the surface of the parts, the horizontal distance between the nozzle and the laser irradiation head is 10-17cm, preferably 12cm.

[0033] To ensure the service life of the nozzle 52, the nozzle 52 is made of copper.
