Technical Field

[0001] This application relates to the field of material replacement technology, specifically to a laser device. Background Technology

[0002] Currently, laser-directed energy deposition (L-DED) equipment processes metal wires through nozzles, which are then melted onto a substrate by a laser. As the nozzle and laser move, or the substrate moves on a multi-axis turntable, the molten metal wires are deposited layer by layer to form the desired shape. Furthermore, L-DED equipment typically has a sealed chamber filled with argon gas to prevent oxidation, and when processing less reactive metals, it can operate using only localized argon or nitrogen gas.

[0003] When changing to different metal wires required for processing, the unwanted metal wires inside the machine need to be emptied, and then the required metal wires are sent to the laser head. This process takes a lot of time. In addition, the machine needs to be opened during the process of changing to new metal wires, and gas purging is required before running it again. The gas purging process takes a lot of time, and such material changing operations also waste the rare gas used for gas purging. Utility Model Content

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1 This application provides a laser device 100 for replacing a metal wire 200 to deposit structures of different materials on a target object. The metal wire 200 can be made of aluminum, titanium, or a substrate, but is not limited thereto. Specifically, the laser device 100 includes a laser mechanism 10 and a material changing mechanism 20.

[0027] Please see also Figure 2 The laser mechanism 10 includes a laser emitter 11 and a laser head 12. The laser emitter 11 is connected to the laser head 12 and is used to emit a laser beam. The laser head 12 has an avoidance channel 121, and the laser beam emitted by the laser emitter 11 is emitted from the avoidance channel 121. The material changing mechanism 20 is located on one side of the laser mechanism 10. The material changing mechanism 20 includes a material changing drive assembly 21 and multiple feeding assemblies 22 for conveying different metal wires 200. The material changing drive assembly 21 is connected to the multiple feeding assemblies 22. Any one of the multiple feeding assemblies 22 can be arranged opposite to the laser head 12 to extend the conveyed metal wire 200 into the clearance channel 121 and coaxial with the laser beam. The material changing drive assembly 21 is used to drive the multiple feeding assemblies 22 to move simultaneously to replace the feeding assembly 22 aligned with the laser head 12. This allows the metal wire 200 on the replaced feeding assembly 22 to pass through the clearance channel 121 of the laser head 12 and be melted by the laser beam at the laser head 12, thereby causing the molten metal wire 200 to be deposited on the target object.

[0028] In the solution provided in this application embodiment, when changing the different metal wires 200 required for processing, the material changing drive component 21 drives multiple feeding components 22 to move simultaneously to replace the feeding component 22 aligned with the laser head 12, so that the metal wires 200 on the replaced feeding component 22 pass through the avoidance channel 121 of the laser head 12 and are melted by the laser beam at the laser head 12, thereby causing the molten metal wires 200 to be deposited on the target object. The entire material changing process is simple to operate, takes less time, improves the material changing efficiency, and does not require opening the machine for gas washing, thus avoiding waste of the rare gas used for gas washing.

[0029] The laser mechanism 10 also includes a first fixing member 13 and a plurality of first deflection plates 14. The first fixing member 13 has a multi-segment bending structure and is connected to the laser emitter 11 and the laser head 12 respectively. A first bending channel 131 communicating with the avoidance channel 121 is opened in the first fixing member 13, and a plurality of first deflection positions 132 are provided in the first bending channel 131. The plurality of first deflection plates 14 are respectively disposed at the plurality of first deflection positions 132. The laser beam emitted by the laser emitter 11 is reflected by the plurality of first deflection plates 14 in the first bending channel 131 and then enters the avoidance channel 121. In this embodiment, the first deflection positions 132 are formed at the vertical bend of the first bending channel 131. There are two first deflection positions 132 and two first deflection plates 14. That is to say, the laser beam emitted by the laser emitter 11 reaches the avoidance channel 121 after two bends.

[0030] By setting the first fixing member 13 and multiple first deflectors 14, the laser beam emitted by the laser emitter 11 can be bent and reflected multiple times to reach the avoidance channel 121, which can reduce the space occupied by the laser mechanism 10 and make the layout of the laser device 100 compact.

[0031] The laser device 100 also includes an imaging mechanism 30, which is located on one side of the laser device 10. The imaging mechanism 30 includes a second fixing member 31, an imaging member 32, and at least one second deflector 33. The two ends of the second fixing member 31 are respectively connected to the first fixing member 13 and the imaging member 32. A second bending channel 311 communicating with the first bending channel 131 is formed in the second fixing member 31. The second bending channel 311 has at least one second deflection position 312, and at least one second deflector 33 is disposed at at least one second deflection position 312. The imaging light of the imaging member 32 is reflected by at least one second deflector 33 in the second bending channel 311 and then reaches the second bending channel 311. In this embodiment, the imaging member 32 is a camera, the second deflection position 312 is formed at the vertical bend of the second bending channel 311, and there is one second deflector 33 and one second deflection position 312.

[0032] By allowing the first bending channel 131 and the second bending channel 311 to share a portion of the channel, and by providing the second fixing member 31 and the second deflector 33, the imaging light from the imaging member 32 can be bent and reflected multiple times to reach the avoidance channel 121, thereby reducing the space occupied by the imaging mechanism 30 and making the layout of the laser device 100 more compact. By providing the imaging member 32, it is possible to monitor whether the metal wire 200 at the laser head 12 has melted.

[0033] Please see also Figure 3 The feeding assembly 22 includes a storage component 221, a straightening component 222, and a feeding component 223. The storage component 221 is used to wind and convey the metal wire 200. The straightening component 222 is located on one side of the storage component 221 and is used to straighten the metal wire 200 conveyed from the storage component 221. The feeding component 223 is located on one side of the straightening component 222 and is used to drive the metal wire 200 straightened by the straightening component 222 to move so that the metal wire 200 extends into the clearance channel 121.

[0034] By coordinating the storage component 221, the straightening component 222, and the feeding component 223, the wound metal wire 200 can be straightened and conveyed into the clearance channel 121. The operation is relatively simple and the efficiency is high.

[0035] The storage unit 221 includes a storage shell 2211, a reel 2212 and a motor 2213. The reel 2212 is rotatably disposed inside the storage shell 2211 and is used to wind up the metal wire 200.

[0036] By placing the metal wire 200 inside the storage shell 2211, a protective layer is formed for the metal wire 200, preventing it from being contaminated with impurities. By winding the metal wire 200 onto the reel 2212, it is convenient to store the metal wire 200. By setting a motor 2213, it is convenient to transport the wound metal wire 200 to the straightening member 222.

[0037] Please see also Figure 4The straightening component 222 includes a straightening body 2220, a straightening shell 2221, two rows of first straightening wheel sets 2222, and two rows of second straightening wheel sets 2223. The straightening body 2220 is disposed inside the straightening shell 2221 and has a first side surface 2220A and a second side surface 2220B perpendicular to each other. The two rows of first straightening wheel sets 2222 are spaced apart from the first side surface 2220A of the straightening body 2220 inside the straightening shell 2221 along the direction perpendicular to the insertion of the metal wire 200. The wire 200 is staggered in its insertion direction to straighten the metal wire 200 extending from the storage unit 221; two rows of second straightening wheel sets 2223 are located below the first straightening wheel set 2222. The two rows of second straightening wheel sets 2223 are spaced apart on the second side 2220B of the straightening body 2220 inside the straightening shell 2221 along the insertion direction perpendicular to the metal wire 200, and the two rows of second straightening wheel sets 2223 are staggered in their insertion direction to straighten the metal wire 200 extending from the first straightening wheel set 2222. In this embodiment, each row of first straightening wheel group 2222 includes 6 first straightening wheels 2222A, and the 6 first straightening wheels 2222A in the two rows are arranged alternately. Each row of second straightening wheel group 2223 includes 6 second straightening wheels 2223A, and the 6 second straightening wheels 2223A in the two rows are arranged alternately.

[0038] By setting two rows of first straightening wheel sets 2222 and two rows of second straightening wheel sets 2223, with the two rows of first straightening wheel sets 2222 spaced apart on the first side 2220A of the straightening body 2220 inside the straightening shell 2221 along the direction perpendicular to the insertion of the metal wire 200, and the two rows of second straightening wheel sets 2223 spaced apart on the second side 2220B of the straightening body 2220 inside the straightening shell 2221, the metal wire 200 can be straightened in different directions, and the straightening effect is good.

[0039] Please see also Figure 5 The feeding component 223 includes a feeding shell 2231, two rows of feeding wheel sets 2232, and a feeding drive component 2233. The two rows of feeding wheel sets 2232 are spaced apart within the feeding shell 2231 and arranged opposite each other along a direction perpendicular to the insertion direction of the metal wire 200, for the metal wire 200 straightened by the straightening component 222 to extend into. The feeding drive component 2233 is located in the feeding shell 2231 and is connected to the two rows of feeding wheel sets 2232 respectively, for driving the two rows of feeding wheel sets 2232 to rotate and move the metal wire 200 so that the metal wire 200 extends into the clearance channel 121. In this embodiment, each feeding wheel set 2232 includes two feeding wheels 2232A, and the two feeding wheels 2232A in the two rows are arranged opposite each other. The feeding drive component 2233 is a drive motor.

[0040] By setting the feeding drive component 2233, power can be provided to rotate the feeding wheel assembly 2232, thereby driving the metal wire 200 to move so that the metal wire 200 extends into the clearance channel 121.

[0041] Please continue reading Figure 1 The material changing drive assembly 21 includes a first material changing drive component 211 and a second material changing drive component 212. The first material changing drive component 211 is connected to multiple feeding components 22 respectively, and is used to drive the multiple feeding components 22 to move simultaneously along a first direction. The second material changing drive component 212 is connected to the first material changing drive component 211, and is used to drive the first material changing drive component 211 to move along a second direction perpendicular to the first direction. In this embodiment, there are two feeding components 22, and both the first material changing drive component 211 and the second material changing drive component 212 are linear modules. The first direction is the Y-axis direction, and the second direction is the X-axis direction.

[0042] By setting the first material changing drive 211 and the second material changing drive 212, not only can the switching between multiple feeding components 22 be realized, thus facilitating the replacement of the metal wire 200, but the position of the feeding component 22 can also be adjusted so that the metal wire 200 conveyed by the feeding component 22 extends into the avoidance channel 121 and is coaxial with the laser beam in the avoidance channel 121.

[0043] In one possible implementation, the laser device 100 further includes a moving mechanism 40, which includes a first moving drive 41 and a second moving drive 42.

The second moving drive 42 is connected to the first moving drive 41 and is used to drive the first moving drive 41 to move along the second direction. In this embodiment, both the first moving drive 41 and the second moving drive 42 are linear modules. The third direction is the Z-axis direction.

[0044] By setting the first moving drive 41 and the second moving drive 42, the positions of the laser emitter 11 and the material changing drive assembly 21 can be easily adjusted so that the laser head 12 is close to the target object, so that the molten metal wire 200 is deposited on the target object.

[0045] In one possible implementation, the laser device 100 further includes an air blowing mechanism 50, which is disposed on one side of the laser head 12 and has an air blowing port 51 disposed toward the end of the laser head 12. In this embodiment, the air blowing mechanism 50 is an air blowing nozzle.

[0046] By setting up the air blowing mechanism 50, foreign objects can be blown away during the processing to prevent them from falling onto the processing area of ​​the target object.

[0047] The implementation process of the laser device 100 in this application embodiment is as follows:

[0048] The first moving drive 41 and the second moving drive 42 cooperate to drive the laser emitter 11 and the material changing drive to move along the first direction and the third direction respectively, so that the laser head 12 approaches the target object;

[0049] The first material changing drive 211 and the second material changing drive 212 cooperate to drive multiple feeding components 22 to move simultaneously along the first direction and the second direction, so that the metal wire 200 conveyed by one of the feeding components 22 extends into the clearance channel 121 and is coaxial with the laser beam in the clearance channel 121.

[0050] The laser emitter 11 emits a laser beam, which is bent and reflected multiple times to reach the avoidance channel 121 and melt the metal wire 200 at the laser head 12, so that the molten metal wire 200 is deposited on the target object.

[0051] When it is necessary to change to a different metal wire 200 for deposition, the first material changing drive 211 and the second material changing drive 212 cooperate to drive multiple feeding components 22 to move simultaneously along the first direction and the second direction, so that another feeding component 22 is aligned with the laser head 12, so that the metal wire 200 conveyed by the other feeding component 22 is extended into the avoidance channel 121 and coaxial with the laser beam in the avoidance channel 121. The laser emitter 11 emits a laser beam, which reaches the avoidance channel 121 after multiple bends and reflections, and melts the metal wire 200 conveyed by the other feeding component 22 at the laser head 12, so that the molten metal wire 200 is deposited on the target object.
