Description

Technical Field

[0001] The embodiments of the present invention relate to the field of composite hair formation technology, specifically, to a composite hair formation device using electrical discharge machining and laser technology. Background Technology

[0002] Both electrical discharge machining (EDM) texturing devices and laser texturing devices are existing technologies used for surface treatment of metal molds. They are mainly used to texturize the surface of rolls or flat molds, processing the working end faces of the rolls and flat molds with tiny, uniform pits and protrusions. After texturing the rolls, they can be used to roll metal sheets, forming corresponding textures on the rolled metal sheets. They can also texturize the surface of flat metal molds, improving the demolding performance of the flat molds and producing uniform texturing textures on the surface of the formed products, thereby improving the performance of the formed products.

[0003] In existing technologies, electrical discharge texturing (EDM) involves using electrodes to perform electrical discharge etching on the workpiece surface to achieve texturing. In contrast, laser texturing uses a laser beam to scan the workpiece surface to achieve texturing. In practical applications, EDM texturing achieves a greater texturing depth and produces a deeper texturing layer compared to laser texturing. However, laser texturing offers better processing efficiency and accuracy compared to EDM.

[0004] However, when roughening planar workpieces, different areas of the workpiece surface have different processing requirements. For example, when processing planar molds, there is a need for deeper roughening of the recessed areas of the planar mold and shallower roughening of the planar areas. This requires a combination of electrical discharge machining (EDM) and laser roughening technologies. Furthermore, there is a need to perform EDM roughening on some areas of the workpiece surface first, and then continue laser roughening on the roughened layer to ensure both processing efficiency and roughening depth. Therefore, the use of combined EDM and laser roughening technology is the main technology for roughening plate-shaped workpieces, mainly planar molds, in the existing technology.

[0005] In existing technologies, when the same area of ​​a planar mold surface needs to be processed sequentially by electrical discharge machining (EDM) and laser texturing, the workpiece must first undergo EDM texturing by immersing it in a working fluid (such as kerosene). After EDM texturing the corresponding area of ​​the workpiece surface, before proceeding with laser texturing, the kerosene and other working media on the workpiece surface must be removed to prevent large sparks from occurring during subsequent laser texturing operations and causing safety accidents. However, in actual operation, this additional workpiece surface cleaning process affects the continuity of the combined EDM and laser texturing process, thus impacting the efficiency of thoroughly texturing the workpiece surface. Summary of the Invention

[0006] To overcome the above-mentioned defects, embodiments of the present invention provide an electrical discharge and laser composite texturing device, which solves the technical problem in the prior art that when performing electrical discharge and laser composite texturing on workpieces, the need to specifically remove kerosene from the workpiece surface affects the efficiency of thoroughly texturing the workpiece surface.

[0007] This invention provides a combined electrical discharge and laser texturing apparatus, comprising an electrical discharge texturing device and a laser texturing device, wherein the electrical discharge texturing device is provided with a working pool, and further comprises: A placement tray is used to place roughened workpieces.

The medium removal assembly is in transmission cooperation with the workpiece moving assembly. The workpiece receiving assembly is provided on the side of the conveying trough away from the working pool. It is used to transfer the workpiece between the upper transverse chamber and the lower transverse chamber. The workpiece receiving assembly is provided with a lifting and flipping structure to keep the workpiece vertical within the working range of the laser texturing equipment.

[0008] In order to place the placement tray into the work pool, the placement tray is further provided with a through groove and an abutment groove at opposite ends. The workpiece passes through the through groove, and one side of the workpiece is in contact with the inner wall of the abutment groove. The bottom of the placement tray is provided with multiple insertion strips.

The rotating base is fixedly connected to the inner bottom wall of the working pool, and a rotating shaft is rotatably connected to the rotating base. Counterweights are eccentrically arranged on both sides of the rotating shaft. The fixing plate is fixedly connected to the rotating shaft, and multiple through holes that mate with the insertion strip are provided on the fixing plate.

[0010] To further offset the placement tray upwards, the downward tilting assembly includes a mounting slot and an arc-shaped downward support. The mounting slot is located at the top of the working pool, and a drive shaft is rotatably connected inside the mounting slot. The arc-shaped downward support is fixedly connected to the drive shaft, and the bottom of the arc-shaped downward support causes the fixing plate to offset along the rotation axis.

[0011] To tilt the conveyor trough, the system further includes a mounting bracket, a screw drive structure, a first electric cylinder, and a slope-shaped abutment support. The top of the mounting bracket is equipped with a rotating shaft seat, on which a sliding platform is rotatably connected. The bottom of the conveyor trough is slidably connected to the sliding platform. The sliding platform is equipped with the screw drive structure that moves the conveyor trough. The mounting bracket is equipped with a first electric cylinder that rotates the conveyor trough around the center point of the rotating shaft seat. Slope-shaped abutment supports are located on both sides of the top of the mounting bracket to support the tilted bottom of the conveyor trough.

[0012] To facilitate the movement of the workpiece between the upper and lower transverse chambers, the workpiece moving assembly further includes moving rollers and support rollers. The moving rollers are driven to be installed on both sides of the middle section of the conveying trough frame. The upper and lower sides of the moving rollers are respectively located between the upper and lower transverse chambers. Multiple support rollers are driven to be installed at the bottom of both the upper and lower transverse chambers.

[0013] To add cleaning agent to the surface of a workpiece coated with a roughening medium, the agent addition structure further includes an installation tank, a wiping cotton layer, a collection tank, a shielding curtain, a flexible drain cylinder, and an agent dispensing assembly. The installation tank is fixedly connected to the bottom of the upper transverse chamber. A drain cylinder is fixedly connected inside the installation tank. The top of the drain cylinder has an installation groove, and the wiping cotton layer is disposed within the installation groove. The wiping cotton layer is located within the upper transverse chamber. The bottom of the installation tank is fixedly connected to the collection tank, which is located at the bottom of the lower transverse chamber. A drain pipe is installed through the collection tank. Shielding curtains are provided on both sides of the bottom of the drain cylinder. Multiple flexible drain cylinders are connected to the bottom of the drain cylinder. Multiple seepage outlets are connected to the side walls of the flexible drain cylinders. The agent dispensing assembly is disposed between the drain cylinder and the wiping cotton layer.

[0014] To remove media and cleaning agents from the workpiece surface, the media removal assembly further includes a mounting shaft, a spiral groove, and a wiping belt layer. The mounting shaft is driven on both sides of the middle section of the conveyor frame. The mounting shaft on the same side is driven by the moving roller. The mounting shaft is located between the upper and lower transverse chambers. The spiral groove is formed on the mounting shaft. Mounting ring grooves are fixedly connected to both sides of the mounting shaft. The wiping belt layer is spirally arranged within the spiral groove and fixedly arranged between the two mounting ring grooves.

[0015] To facilitate the transfer of the workpiece between the upper and lower transverse chambers, the workpiece receiving assembly further includes a T-shaped groove frame, clamping rollers, and a rotating ring. Two receiving rollers are rotatably connected to one side of the T-shaped groove frame facing the conveying groove frame. Multiple clamping rollers are equidistantly arranged on the upper and lower sides of the T-shaped groove frame. The rotating ring is fixedly sleeved on the T-shaped groove frame.

[0016] To adjust the height and circumferential position of the T-shaped slot frame, the lifting and tilting structure further includes a lifting bracket and a second electric cylinder. A mounting ring is longitudinally slidably connected inside the lifting bracket, and a rotating ring is rotatably connected inside the mounting ring. The bottom of the lifting bracket is provided with a second electric cylinder that drives the mounting ring to move longitudinally.

[0017] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, after the workpiece processed by the electrical discharge texturing equipment is removed from the working pool, it is moved to the conveying trough. The workpiece with liquid medium adhering to it first moves in the lower transverse chamber. When the workpiece passes through the area between the drain tank and the collection tank, multiple flexible drain cylinders come into contact with multiple recessed areas on the top of the workpiece. The cleaning agent discharged by the flexible drain cylinders fully contacts the top area of ​​the workpiece, allowing the cleaning agent to fully mix with the liquid medium. Then, as the workpiece continues to move, the top of the workpiece comes into contact with the mounting shaft wrapped with a wiping tape layer. The wiping tape layer wipes and cleans the top of the workpiece and the inside of the recessed area on the top of the workpiece. The wiping depth of the wiping tape layer is close to 2.5 cm, which can wipe the recessed area on the top of the workpiece. Then, the workpiece is transferred to the upper transverse chamber to continue moving, so that the bottom of the workpiece comes into contact with the wiping cotton layer, cleaning the liquid medium adhering to the bottom of the workpiece. This prevents the liquid medium from affecting the laser texturing operation in the subsequent process.

[0018] 2. In this invention, after the workpiece is subjected to electrical discharge texturing, the workpiece can be directly moved from the working pool to the conveying trough. After the liquid medium on the surface of the workpiece is treated, the workpiece can be directly and vertically conveyed into the laser texturing equipment, which effectively improves the convenience of moving the workpiece during the combined processing of electrical discharge texturing and laser texturing.

[0027] like Figures 1 to 11As shown, this invention discloses a composite texturing device combining electrical discharge machining (EDM) and laser, comprising an EDM texturing device 1 and a laser texturing device 2. The EDM texturing device 1 is equipped with a working pool 3. The EDM texturing device 1 is a prior art technique for texturing the surface of workpieces such as rolls and flat dies. During the actual texturing operation, a liquid medium (kerosene) is added to the working pool 3, and then the workpiece to be texturized is placed in the working pool 3. The working pool 3 is generally also equipped with a dedicated device for circulating and filtering the liquid medium. The working electrode of the EDM texturing device 1 is close to the workpiece, utilizing... Pulse-based texturing of the workpiece surface is performed, while laser texturing equipment 2 does not require a liquid medium during operation. The laser output end of laser texturing equipment 2 is directly brought close to the workpiece, and a laser beam is directly emitted to texturize the workpiece surface. Both the working electrode of electrical discharge texturing equipment 1 and the laser output end of laser texturing equipment 2 are equipped with an XYZ three-axis moving structure for adjusting the processing area of ​​the working electrode and the laser output end. The electrical discharge texturing equipment 1 and laser texturing equipment 2, as well as the corresponding existing equipment, are all prior art known to those skilled in the art.

[0028] like Figures 1 to 3 As shown, it also includes a placement tray 4 for placing the roughened workpiece. The two ends of the placement tray 4 are respectively provided with a through groove 8 and an abutment groove 9. The workpiece passes through the through groove 8, and one side of the workpiece is in contact with the inner wall of the abutment groove 9. The bottom of the placement tray 4 is provided with multiple insertion strips 10. When it is necessary to roughen the surface of the workpiece, the placement tray 4 is first placed into the work pool 3 through the insertion strips 10. Then, when it is necessary to move the workpiece into the placement tray 4 and fix the position of the workpiece, the size of the placement tray 4 is made to correspond to the size of the workpiece to be processed. Then, after the placement tray 4 is tilted, the workpiece is passed through one side of the through groove 8 so that one end of the workpiece is in contact with the inner wall of the abutment groove 9. The workpiece used for processing in this invention is usually a flat mold for forming, and generally only a single-sided roughening operation is required. like Figures 1 to 5As shown, a rotating placement assembly is provided inside the working pool 3, and a placement tray 4 is placed on the rotating placement assembly. The rotating placement assembly includes a rotating base 11 and a fixing plate 14. The rotating base 11 is fixedly connected to the inner bottom wall of the working pool 3, and a rotating shaft 12 is rotatably connected to the rotating base 11. Counterweights 13 are eccentrically arranged on both sides of the rotating shaft 12. The fixing plate 14 is fixedly connected to the rotating shaft 12, and multiple through holes that mate with the insertion strips 10 are opened on the fixing plate 14. The placement tray 4 is fixed to the working pool 3 by the insertion strips 10. The corresponding multiple through-holes are used to fix the placement tray 4 in the fixing plate 14. Then, one side of the fixing plate 14 is pressed down to make the fixing plate 14 rotate along the rotating shaft 12, causing the side of the placement tray 4 with the through groove 8 to tilt upward, so that one end of the workpiece is exposed from the liquid medium. After the workpiece is replaced, the pressing on one side of the fixing plate 14 is stopped. Under the action of the counterweight 13, the rotating shaft 12 is reset, and the buoyancy of the liquid medium on the placement tray 4 is used to make the placement tray 4 reset and keep it parallel. like Figures 1 to 3 As shown, a downward tilting component that cooperates with the rotating placement component is provided on one side of the working pool 3, which drives the placement tray 4 to shift upward. The downward tilting component includes a mounting bracket 15 and an arc-shaped downward pressure bracket 17. The mounting bracket 15 is located on the top of the working pool 3. A drive shaft 16 is rotatably connected inside the mounting bracket 15. The arc-shaped downward pressure bracket 17 is fixedly connected to the drive shaft 16. The bottom of the arc-shaped downward pressure bracket 17 drives the fixed hole plate 14 to shift along the rotating shaft 12. A first drive motor 45 is provided on one side of the mounting bracket 15. The output end of the first drive motor 45 is fixedly connected to the drive shaft 16. When it is necessary to press one side of the fixed hole plate 14 downward, the first drive motor 45 is started to drive the drive shaft 16 to rotate, which drives the arc-shaped downward pressure bracket 17 to move downward and press the fixed hole plate 14 downward.

[0029] like Figures 1 to 7As shown, it also includes a mounting bracket 18, a screw drive structure 21, a first electric cylinder 22, and a sloped abutment support 23. A rotating shaft seat 19 is provided on the top of the mounting bracket 18, and a sliding platform 20 is rotatably connected to the rotating shaft seat 19. The bottom of the conveying trough frame 5 is slidably connected to the sliding platform 20. A screw drive structure 21 for moving the conveying trough frame 5 is provided on the sliding platform 20. A first electric cylinder 22 for rotating the conveying trough frame 5 along the center point of the rotating shaft seat 19 is provided on the mounting bracket 18. Sloped abutment supports 23 are provided on both sides of the top of the mounting bracket 18 to support the bottom of the inclined conveying trough frame 5. During shutdown, the conveying trough frame 5... The bottom end of the frame 5 contacts the sloping abutment supports 23 on both sides to support the conveying trough frame 5. The tilt angle of the conveying trough frame 5 is consistent with the tilt angle of the placement tray 4. Through the screw transmission structure 21 driven by the motor drive equipment, the conveying trough frame 5 is driven to slide on the sliding platform 20, so that the workpiece located on the side of the placement tray 4 enters the lower transverse chamber 7, and the workpiece is smoothly moved out of the working pool 3 and into the lower transverse chamber 7. When it is necessary to transport the workpiece in parallel, the first electric cylinder 22 is started to drive the conveying trough frame 5 to rotate along the center point of the rotating shaft seat 19, so that the conveying trough frame 5 remains parallel, which facilitates the parallel movement of the workpiece into the laser texturing equipment 2.

[0030] like Figure 1 , Figures 6 to 8 As shown, the conveying trough 5 is set on one side of the working pool 3. The conveying trough 5 is provided with an upper transverse moving chamber 6 and a lower transverse moving chamber 7. A workpiece moving assembly is set between the upper transverse moving chamber 6 and the lower transverse moving chamber 7. The workpiece moving assembly includes moving rollers 24 and support rollers 25. Moving rollers 24 are driven to be installed on both sides of the middle part of the conveying trough 5. The upper and lower sides of the moving rollers 24 are respectively located between the upper transverse moving chamber 6 and the lower transverse moving chamber 7. Multiple support rollers 25 are driven to be installed at the bottom of the upper transverse moving chamber 6 and the lower transverse moving chamber 7. After one end of the workpiece enters the lower transverse moving chamber 7, the workpiece moves between the upper and lower corresponding moving rollers 24 and support rollers 25, driving the moving rollers 24 to rotate and move the workpiece into the lower transverse moving chamber 7. Then, after the workpiece is moved out of the lower transverse moving chamber 7, it is driven to move from the upper transverse moving chamber 6 by the moving rollers 24, thus completing the removal of liquid medium from the surface of the workpiece.

[0031] like Figure 1 , Figures 6 to 9As shown, both sides of the upper transverse chamber 6 and the lower transverse chamber 7 are provided with a chemical addition structure for adding chemicals to the workpiece moving between the upper transverse chamber 6 and the lower transverse chamber 7. The chemical addition structure includes an installation tank 26, a wiping cotton layer 29, a collection tank 30, a shielding curtain 32, a flexible drain cylinder 33, and a chemical dispensing assembly. The installation tank 26 is fixedly connected to the bottom of the upper transverse chamber 6. A drain cylinder 27 is fixedly connected inside the installation tank 26. An installation groove 28 is provided at the top of the drain cylinder 27, and a wiping cotton layer 29 is provided inside the installation groove 28. The wiping cotton layer 29 is located inside the upper transverse chamber 6. The collection tank 30 is fixedly connected to the bottom of the installation tank 26. The collection tank 30 is located at the bottom of the lower transverse chamber 7. A drain pipe 31 is installed through the collection tank 30. Shielding curtains 32 are provided on both sides of the bottom of the drain cylinder 27. The bottom of the drain cylinder 27 is connected to a... Multiple flexible drainage cylinders 33 are connected to multiple seepage ports 34 on their side walls. A chemical injection assembly is provided between the drainage port 27 and the wiping cotton layer 29. When the workpiece moves from the lower transverse chamber 7, it first passes through the shielding curtain 32 and contacts the multiple flexible drainage cylinders 33. The seepage port 34 is provided with a blocking medium, but it can allow the cleaning agent to flow out slowly. After the cleaning agent flows out to the top end face and recess of the workpiece, it causes the cleaning agent and the liquid medium to dissolve and react, so that the liquid medium no longer adheres to the surface of the workpiece. Then it is convenient to wipe the cleaning agent and liquid medium off the surface of the workpiece. Then the position of the workpiece continues to move, so that the workpiece moves into the upper transverse chamber 6. During the movement, the bottom of the workpiece contacts the top of the wiping cotton layer 29, so that the cleaning agent contacts the bottom of the workpiece. Then the bottom of the workpiece is wiped to remove the liquid medium. It should be noted that the workpiece used for processing in this invention is usually a flat mold for forming. The top of the workpiece is a recessed area corresponding to the shape of the product, while the bottom of the workpiece is a flat area. When actually removing the liquid medium attached to the workpiece, a flexible drain cylinder 33 that can be bent is used to fully contact the recessed area inside the workpiece so that the cleaning agent comes into contact with the recessed area of ​​the workpiece. Then, when the workpiece is moved from the upper transverse chamber 6, a wiping cotton layer 29 containing the cleaning agent is used to adhere to the flat bottom of the workpiece to wipe the bottom of the workpiece and remove the liquid medium from the bottom of the workpiece. During the process of discharging the cleaning agent through the flexible drain cylinder 33, the cleaning agent and liquid medium are collected by the collection tank 30 and then discharged through the drain pipe 31. The use of the shielding curtain 32 can prevent the cleaning agent and liquid medium from splashing randomly. The cleaning agent filling assembly includes a three-way filling pipe 46, which has a filling port and two drain ports. One drain port is connected to the drain tank 27, and the other drain port is connected to an outlet pipe 47. The top of the outlet pipe 47 has multiple outlet holes. When cleaning agent needs to be added to the drain tank 27 and the wiping cotton layer 29, the cleaning agent is added to the three-way filling pipe 46 through the filling port, and then discharged through the two drain ports. Some of the cleaning agent is discharged directly into the drain tank 27, and after being discharged through the outlet holes on the outlet pipe 47, the cleaning agent keeps the wiping cotton layer 29 moist, thus achieving the purpose of removing the liquid medium adhering to the workpiece using the cleaning agent. Furthermore, when the wiping cotton layer 29 becomes dirty, it can be removed and replaced.

[0032] A media removal assembly for removing the texturing medium and reagents is provided between the upper transverse chamber 6 and the lower transverse chamber 7. The media removal assembly is driven by the workpiece moving assembly. The media removal assembly includes a mounting shaft 35, a spiral groove 36, and a wiping belt layer 37. Mounting shafts 35 are driven on both sides of the middle part of the conveyor frame 5. The mounting shafts 35 on the same side are driven by the moving roller 24. The mounting shafts 35 are located between the upper transverse chamber 6 and the lower transverse chamber 7. The mounting shafts 35 have spiral grooves 36. Mounting ring grooves are fixedly connected to both sides of the mounting shafts 35. The wiping belt layer 37 spirals... The wiping belt layer 37 is fixedly positioned between two mounting ring grooves within the spiral groove 36. After the cleaning agent is applied to the workpiece, the mounting shaft 35 and the fixed wiping belt layer 37 rotate, allowing the wiping belt layer 37 to effectively remove the cleaning agent and liquid medium adhering to the workpiece. The wiping depth of the wiping belt layer 37 is close to 2.5 cm, which can wipe and absorb the recessed areas on the top of the workpiece. For areas on the workpiece that the wiping belt layer 37 cannot reach, the cleaning agent and liquid medium on the surface of the workpiece can be manually removed by the operator after the workpiece is removed from the conveyor frame 5. When the surface of the wiping tape layer 37 becomes dirty, the wiping tape layer 37 can be removed from the spiral groove 36 and replaced. Both the mounting shaft 35 and the movable roller 24 are fixedly connected to a connecting shaft 48. Both connecting shafts 48 on the same side are equipped with transmission gears 49. A transmission belt 50 is provided between the two transmission gears 49. Both sides of the conveying trough frame 5 are equipped with a second drive motor 51. The second drive motor 51 is fixedly connected to the corresponding connecting shaft 48. When the second drive motor 51 is started, it can drive the mounting shaft 35 and the movable roller 24 on the same side to rotate in the same direction.

[0033] like Figure 1 , Figure 6 and Figure 11As shown, a workpiece receiving assembly is provided on the side of the conveyor frame 5 away from the work pool 3 for transferring workpieces between the upper transverse chamber 6 and the lower transverse chamber 7. The workpiece receiving assembly includes a T-shaped trough 38, clamping rollers 40, and a rotating ring 41. Two receiving rollers 39 are rotatably connected to the side of the T-shaped trough 38 facing the conveyor frame 5. Multiple clamping rollers 40 are equidistantly arranged on the upper and lower sides of the T-shaped trough 38. A rotating ring 41 is fixedly sleeved on the T-shaped trough 38. When it is necessary to transfer the workpiece from the lower transverse chamber 7 to the upper transverse chamber... When the workpiece is moved out of the lower transverse chamber 7, it will enter the T-shaped slot 38. Then, the height of the T-shaped slot 38 is adjusted to correspond to the height of the upper transverse chamber 6, and the receiving roller 39 is driven to rotate, so that the workpiece is transported back to the upper transverse chamber 6. A third drive motor 52 is provided on the T-shaped slot 38. The output end of the third drive motor 52 is fixedly connected to the receiving roller 39 located on the lower side. Starting the third drive motor 52 can drive the receiving roller 39 to rotate, so as to realize the movement of the workpiece in and out of the T-shaped slot 38. The workpiece receiving assembly is equipped with a lifting and flipping structure to keep the workpiece vertical within the working range of the laser texturing equipment 2. The lifting and flipping structure includes a lifting bracket 42 and a second electric cylinder 44. A mounting ring 43 is longitudinally slidably connected inside the lifting bracket 42, and a rotating ring 41 is rotatably connected inside the mounting ring 43. The bottom of the lifting bracket 42 is equipped with a second electric cylinder 44 that drives the mounting ring 43 to move longitudinally. When it is necessary to adjust the height of the T-shaped slot frame 38, the second electric cylinder 44 is activated to drive the mounting ring 43 to move longitudinally. A gear segment 53 is provided on the outer arc surface of the rotating ring 41, and a fourth drive motor 54 is provided at the bottom of the mounting ring 43. A drive gear 55 is driven on the gear segment 53. The drive gear 55 is located at the output end of the fourth drive motor 54. When the fourth drive motor 54 is activated, the drive gear 55 is driven to rotate, thereby causing the gear segment 53, the rotating ring 41, and the T-shaped slot frame 38 to flip, keeping the workpiece inside the laser texturing equipment 2 vertical, so that the laser texturing equipment 2 can continue to perform laser texturing operations on the concave area of ​​the workpiece.

[0034] The working principle of this combined electrical discharge and laser texturing device: Placement tray 4 is placed into working pool 3 through insertion strip 10. Then, the workpiece needs to be moved into placement tray 4. The top of the workpiece is roughened by electrical discharge machining equipment 1. After the roughening operation is completed, the first drive motor 45 is started to drive drive shaft 16 to rotate, which drives arc-shaped pressing bracket 17 to move downward and press down on fixing plate 14. This causes the side of placement tray 4 with through groove 8 to tilt upward, so that one end of the workpiece is exposed from the liquid medium. The screw drive structure 21, driven by a motor-driven device, drives the conveyor trough 5 to slide on the sliding platform 20, allowing the workpiece located on the side of the placement tray 4 to enter the lower transverse chamber 7. This allows the workpiece to smoothly move from the working pool 3 into the lower transverse chamber 7. The moving roller 24 moves the workpiece within the lower transverse chamber 7. The workpiece first passes through the shielding curtain 32 and contacts multiple flexible drain cylinders 33. After the cleaning agent flows out to the top end face and recess of the workpiece, a dissolving reaction occurs between the cleaning agent and the liquid medium, preventing the liquid medium from adhering to the workpiece surface. Then… The wiping belt layer 37 can remove the cleaning agent and liquid medium adhering to the workpiece. Then, the position of the workpiece is moved and the workpiece will enter the range of the T-shaped groove 38. Then, the height of the T-shaped groove 38 is adjusted to correspond to the height of the upper transverse chamber 6, and the receiving roller 39 is driven to rotate to transport the workpiece back into the upper transverse chamber 6. During the movement, the bottom of the workpiece contacts the top of the wiping cotton layer 29, so that the cleaning agent contacts the bottom of the workpiece. Then, the bottom of the workpiece is wiped to remove the liquid medium. Finally, the cleaned workpiece is moved into the T-shaped groove 38. Then, the T-shaped slot frame 38 is rotated to keep the T-shaped slot frame 38 and the workpiece vertical. Finally, the laser texturing equipment 2 is used to texturize the corresponding areas on the workpiece that have not been texturized, and to perform laser texturing on the areas exposed on the outside of the T-shaped slot frame 38 that have been texturized by electrical discharge machining.
