Description

Technical Field

[0001] This invention relates to the field of laser processing, and more specifically to a medium switching device for laser processing. Background Technology

[0002] Currently, traditional laser processing platforms mostly focus on automating single actions, failing to meet the demands for complex motions requiring simultaneous precision lifting, multi-dimensional rotation, and adaptive clamping. Regarding processing environment control, while some high-end platforms can support the introduction of specific processing media (such as protective gases or auxiliary liquids), their media supply systems generally have significant shortcomings, as detailed below:

[0003] First, the existing system design is rigid, usually only pre-setting a single or limited type of media channel, and cannot quickly and seamlessly switch between multiple media according to the processing sequence (such as needing to switch to water environment treatment immediately after air cutting, and then switch to a specific gas environment for post-processing).

[0004] Secondly, existing sealing structures are mostly designed for single media or static working conditions. They are difficult to maintain the absolute seal of the processing cavity during dynamic media switching and workpiece / actuator movement, which poses a risk of media leakage.

[0005] Furthermore, existing machining platforms generally lack a systematic consideration of the problem of residual media after machining. If different media (especially liquids) cannot be completely removed after switching or machining, they will remain on the surface of the workpiece or inside the cavity, which will seriously contaminate the subsequent machining environment. Summary of the Invention

[0006] To address the technical problems existing in the prior art, this invention discloses a medium switching device for laser processing.

[0007] It can be used in fields such as aerospace and medical devices that are sensitive to the medium environment and have stringent process requirements. This equipment is a fully integrated automation solution that integrates intelligent adaptive clamping, multi-medium sealed leak-free switching and cleaning functions to support advanced laser manufacturing processes with high efficiency, high quality and low risk.

The sealing cover is inserted into the processing platform, and the two are combined to form a sealing chamber. Cleaning modules are provided on the outside of the media switching module and on the other side of the processing platform module.

[0012] Along the Y direction, a clamping module is set on each side of the machining platform module; the clamping module is used to clamp the workpiece located on the machining platform, and the clamping module includes a clamping block.

[0018] As a further technical solution, a sliding groove is provided on the connecting rod of one of the clamping modules, a moving block is provided on the sliding groove, and a fifth adsorption block is connected to the moving block.

[0019] As a further technical solution, along the X direction, the side of the sealing cover is also provided with a sliding groove that cooperates with the connecting rod of the clamping module.

[0020] As a further technical solution, the support platform module can be raised and lowered.

[0021] As a further technical solution, the cleaning module can be moved along the X direction under the drive of the driving device.

Therefore, they should not be construed as limitations on this invention.

[0057] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, the present invention proposes a medium switching device and method for laser processing.

[0058] The present invention is mainly composed of five modules: a media switching module 1, a processing platform module 2, a clamping module 3, a cleaning module 4, and a support platform module 5. The media switching module 1, the processing platform module 2, the clamping module 3, the cleaning module 4, and the laser processing module 6 are arranged on the top of the support platform module 5.

[0059] The processing platform module 2 is a workpiece placement module, which mainly realizes the rotation and lifting of the workpiece 7 and the processing platform 31 to facilitate the realization of processing position and function; it includes a processing platform, which can be lifted and rotated under the drive of the first drive system.

[0060] Along the X direction, the media switching module 1 is fixed to one side of the processing platform module 2 (in Figure 1Located on the right side of the processing platform module 2, the medium switching module mainly realizes automatic switching of media and sealing for the workpiece 7. The medium switching module includes a sealing cover, which can be flipped under the drive of the second drive system and moves linearly relative to the processing platform. The sealing cover is inserted into the processing platform, and the two are combined to form a sealing chamber.

[0061] Along the Y-direction, clamping module 3 is located above support platform module 5, mainly for clamping the workpiece 7 being processed. Its position is adjusted according to the size of the workpiece 7 to achieve adaptive clamping. Two clamping modules 3 are provided, located on either side of processing platform module 2. Figure 1 As shown, one clamping module 3 is located on the front side of the processing platform module 2, and the other clamping module 3 is located on the rear side of the processing platform module 2.

[0062] Along the X direction, cleaning modules 4 are provided on the outside of the media switching module 1 and on the other side of the processing platform module. The cleaning modules 4 are mainly used to clean and dry the workpiece 7 in environments requiring cleaning, such as after processing or during media switching. For ease of demonstration, all modules are encapsulated and normally waterproof. In this embodiment, the cleaning module 4 is located on one side of the processing platform module 2 (in...). Figure 1 (Located on the left side of machining platform module 2).

[0063] Laser processing module 6 is a laser processing module, mainly used for processing workpiece 7. It is a three-degree-of-freedom movement module and is located above processing platform module 2.

[0064] This invention achieves complete sealing of the workpiece space through the cooperation of the media switching module, the processing platform module, and the clamping module, thereby enabling rapid, seamless, and automatic switching of multiple media and preventing media leakage. Specifically, the workpiece is placed on the processing platform module, and the clamping module clamps the workpiece. The media switching module ensures sealing before media injection.

[0065] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the medium switching module 1 in this embodiment includes a sealing cover 16 and a second drive system. The second drive system includes a linear drive device and a flip drive device. The linear drive device includes a sealing platform 17, a sealing module moving rack 11, a sealing module slide rail 12, a sealing module drive motor 13, and a sealing module slider 116. The flip drive device includes a sealing module worm gear 14, a sealing module worm wheel 15, a sealing platform 17, a sealing bearing 18, a bearing support frame 19, a sealing motor 110, a sealing module moving plate 111, a sealing drive shaft 112, a sealing connecting block 113, a sealing module gear 114, and a drive rod 115.

[0066] The sealing module moving rack 11 and the sealing module slide rail 12 are fixed on the sealing platform 17. The sealing module drive motor 13 drives the sealing module gear 114 to mesh with the sealing module moving rack 11, so as to realize the movement of the sealing module slider 116 on the sealing module slide rail 12, thereby realizing the movement of the sealing module moving plate 111 in the X direction.

[0067] Furthermore, a sealing motor 110 is fixed on the sealing module moving plate 111. The output end of the sealing motor 110 is connected to the sealing module worm gear 14. The sealing module worm gear 14 meshes with the sealing module worm wheel 15. The sealing module worm wheel 15 is fixedly connected to the sealing drive shaft 112 through a keyway. The sealing drive shaft 112 is connected to the bearing support frame 19 through a sealing bearing 18. A sealing connecting block 113 is sleeved on the sealing drive shaft 112. The sealing connecting block 113 is fixedly connected to the sealing cover 16. The sealing cover 16 has an input hole and an output hole for inputting and outputting media. The media storage device 117 and the media storage device 118 are fixed on the rotating platform 21.

[0068] The sealing cover 16 is provided with sliding grooves on both sides, which cooperate with the connecting rod of the clamping module 3 below. During the sealing process, the sealing cover 16 moves towards the processing platform module 2 under the drive of the linear drive device, and is inserted into the processing platform module 2 from one side of the processing platform module 2, forming a sealing chamber together with the processing platform 231 on the processing platform module 2.

[0069] like Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, the processing platform module 2 in this embodiment includes a processing platform 231 and a first drive system; the first drive system includes a lifting drive device and a rotary drive device, wherein the lifting drive device includes a lifting drive motor 23, a first lifting module synchronous pulley 210, a lifting module synchronous belt 29, a second lifting module synchronous pulley 211, a drive screw 212, a lifting module 25, a lifting module slider 26, a lifting module slide rail 22, etc., and the rotary drive device includes a rotary module motor 28, a second rotary module synchronous pulley 215, a rotary module synchronous belt 216, a rotary module synchronous pulley fixing member 214, a rotary module worm gear 219, a module output rod 220, and a rotary platform 21, etc.

[0070] The lifting drive motor 23 is fixed on the module base 24, and its output shaft is connected to the first lifting module synchronous pulley 210. The first lifting module synchronous pulley 210 realizes the rotation of the second lifting module synchronous pulley 211 through the lifting module synchronous belt 29, so as to drive the drive screw 212. The drive screw 212 drives the lifting module 25 through the nut, so that the lifting module slider 26 moves on the lifting module slide 22, and finally realizes the lifting module 25 rising and falling.

[0071] The rotary module motor 28 is fixed to the lifting module 25 via the rotary module motor mounting bracket 218. It is connected to the second rotary module synchronous pulley 215, which in turn connects to the rotary module synchronous belt 216, ultimately enabling the rotation of the rotary module synchronous belt 216. The rotary module synchronous pulley fixing member 214 is used to fix the second rotary module synchronous pulley 215. The rotary module synchronous belt 216 drives the rotation of the rotary module worm gear 219, which meshes with the rotary module worm wheel 221. This ultimately enables the rotation of the module output rod 220, which is fixedly connected to the rotary platform 21 to achieve the rotation of the rotary platform 21. The rotary platform 21 has a rotary platform slot 27 for placing the media switching module 1.

[0072] The support member 230 has a bearing on its inner side that connects to the module output rod 220. The support member 230 is a fixed end. The support member 230 supports a processing platform 231, which is L-shaped. A first slide rail 225 and a second slide rail 229 are provided on the horizontal surface of the processing platform 231. Rollers are provided on the inner side of the first slide rail 225 and the second slide rail 229 to allow the sealing cover 16 to slide. A sliding second adsorption block 223 is provided on the outer side of the first slide rail 225. The second adsorption block 223 has a relatively large sliding range and can pass through the vertical surface of the processing platform 231 to slide to the outside of the processing platform 231, mainly to accommodate workpieces of different sizes. Therefore, a through hole is provided on the vertical surface of the processing platform 231.

[0073] A first sealing block 224 is provided on the inner side of the second adsorption block 223, and a first adsorption block 222 is provided on the outer side of the second adsorption block 223; the function of the first adsorption block 222 is mainly to fix the connecting rod 321 and the moving block 314 below; the second adsorption block 223 is mainly to adsorb the sealing cover 16, so as to fix the two.

[0074] A fourth adsorption block 227 is provided on the outside of the second slide 229, and a second sealing block 228 is provided on the inside of the fourth adsorption block 227; the fourth adsorption block 227 and the second sealing block 228 are integrated; the fourth adsorption block 227 is mainly for adsorbing the sealing cover 16; thus fixing the two.

[0075] Furthermore, the third adsorption block 226 is fixed to the vertical surface of the processing platform 231, mainly for adsorbing the sealing cover 16; thus achieving the fixation of the two.

[0076] The first sealing block 224 and the second sealing block 228 mentioned above are mainly for cooperating with the sliding groove of the sealing cover 16 to achieve sealing of the sealing cover 16.

[0077] like Figure 14 , Figure 15 , Figure 16 As shown, the two clamping modules 3 in this embodiment can move in the Y and X directions and can extend and retract in the Y direction. Specifically, one of the clamping modules 3 includes a clamping module fixing part 31, a clamping module drive motor 32, a clamping module moving plate 33, a first clamping block 34, a base 35, a first support rod 36, a clamping module lead screw 37, a telescopic motor fixing part 38, a telescopic motor 39, a lead screw motor 310, a second support rod 311, a telescopic plate 312, a fifth adsorption block 313, a moving block 314, a nut block 315, a nut 316, a connecting block 317, a lead screw motor fixing part 318, and a connecting rod 321.

[0078] The clamping module fixing part 31 is fixed on the support platform 51. The clamping module drive motor 32 can drive the clamping module moving plate 33 to move. A base 35 is provided on the clamping module moving plate 33, and a lead screw motor 310 is provided on the base 35. The lead screw motor 310 can drive the nut 316 to realize the movement of the moving platform 320. The telescopic motor 38 is fixed to the moving platform 320. The telescopic cylinder 39 can drive the telescopic plate 312 to extend and retract by rotating. The telescopic plate 312 is connected to the first clamping block 34 through the connecting rod 321. The extension and retraction of the telescopic plate 312 can move the position of the first clamping block 34. A sliding groove is provided on the connecting rod 321, and a moving block 314 is provided in the sliding groove. The fifth adsorption block 313 is fixed to the moving block 314. When the fifth adsorption block 313 slides to the outside of the sealing cover, it adsorbs on the outside of the sealing cover. After the second adsorption block 223 moves, the first sealing block 224 cannot completely block the sliding groove of the sealing cover. Therefore, the fifth adsorption block 313 is designed to block the leaking sliding groove and ensure the sealing performance of the sealing chamber. When the moving block 314 moves into place, it adsorbs with the first adsorption block 222.

[0079] Furthermore, the structure of the other clamping module 3 in this embodiment is basically the same as that of the clamping module described above, such as... Figure 16 As shown, the clamping module is equipped with a moving platform 320, on which a second clamping block 319 is provided. The main difference is that the clamping module is mainly used to position and fix one end of the workpiece, therefore, a fifth adsorption block 313 and a moving block 314 are not provided on it; the rest of the structure is the same as the clamping module described above.

[0080] Furthermore, such as Figure 17 , Figure 18 As shown, the cleaning module 4 in this embodiment can move along the X direction, and includes a first material box 41, a nozzle 42, a connecting pipe 43, a cleaning module moving plate 44, a first connector 45, a second material box 46, a cleaning module drive motor 47, a second connector 48, and a third connector 49.

[0081] The cleaning module 4 is located on the support platform 51, and the first material box 41 and the second material box 46 are material storage. The cleaning module moving plate 44 is driven by the cleaning module drive motor 47. The first connector 45 and the second connector 48 are the air port and water port, respectively. This device is a cleaning equipment. The third connector air port 49 is on the other side. The drying equipment of this device cleans the materials through the nozzle 42.

[0082] Furthermore, such as Figure 19As shown, the support platform module 5 in this embodiment includes a support platform 51, a fixing frame 52, a lifting cylinder 53, and a fixing profile 54; the support platform 51 is fixed to the fixing profile 54, the fixing frame 52 is fixed to the base, and the lifting cylinder 53 is a power source that drives the support platform 51 to lift.

[0083] Furthermore, the laser processing module 6 in this embodiment is a laser processing device with three degrees of freedom, which will not be explained further.

[0084] The specific workflow of the above equipment is as follows;

[0085] First, the workpiece 7 is placed on the processing platform 231 of the processing platform module 2. The processing platform 231 has a built-in vibration damper. The rotation of the processing platform module 2 is mainly used when switching media, while the lifting is used to adjust the position of the workpiece 7 and to avoid interference with other modules when switching media.

[0086] Then, the workpiece 7 is first clamped by the clamping module 3. The clamping module 3 drives the position of the first clamping block 34 through the clamping module drive motor 32 and the lead screw motor 310. On the other side is the second clamping block 319. Note that the second clamping block 319 is in a fixed position, that is, it must be moved to a certain coordinate, while the first clamping block 34 is adjustable and fixed. The position of the fifth suction block 313 is the position that the moving block 314 needs to move when the workpiece 7 is being processed to its maximum size. Through the clamping of the first clamping block 34 and the second clamping block 319, the workpiece 7 is fixed.

[0087] At this moment, the medium switching module 1 achieves sealing before medium injection. This is mainly achieved by the sealing module 13 driving the motor to move the sealing module moving plate 111, and then by rotating the sealing module worm gear 14 to flip the sealing cover 16 so that the sealing cover 16 can be inserted into the first slide 225 and the second slide 229. There are slots of different lengths on both sides of the sealing cover 16. The shorter one corresponds to the second clamping block 319, and the longer one corresponds to the first clamping block 34.

[0088] The first sealing block 224 and the second sealing block 228 are fixed to the corresponding slots on the sealing cover 16 to achieve sealing; wherein the first adsorption block 222 moves together with the second adsorption block 223, and the vertical plane where the third adsorption block 226 is located has a through hole, which allows the second adsorption block 223 to extend out, thereby enabling the movement of locking blocks of different sizes. When the blocks are in place, the adsorption blocks begin to work.

[0089] The first adsorption block 222 adsorbs the first clamping block 34, while the second adsorption block 223 and the fourth adsorption block 227 adsorb the sealing cover 16.

[0090] During the movement, the fifth adsorption block 313 moves with the moving block 314, and the fifth adsorption block 313 is fixed to the other side of the sealing cover 16 to achieve sealing of workpieces 7 of different sizes. The sealed structure can... Figure 20 , Figure 21 ;

[0091] When the seal is released, the sealing cover 16 first retracts, and then the medium cleaning is achieved through the cleaning module 4. When switching media, the rotating platform 21 is rotated through the processing platform module 2 mechanism, and then each adsorption block returns to its original position along with the first clamping block 34 and the second clamping block 319, thereby releasing the adsorption blocks. Then, the clamping module 3 mechanism is retracted. When switching media, the clamping module 3 mechanism needs to be moved to one side and raised and lowered by the lifting cylinder 53 of the supporting platform module 5 mechanism to avoid interference with the rotating platform 21, so as to achieve media switching.

[0092] The process should be as follows: When the processing of a certain medium is completed, the height of the cleaning module 4 is first adjusted by the support platform module 5, and the cleaning module 4 is moved to clean the workpiece 7.
