Description

Technical Field

[0001] This invention relates to the field of laser marking technology, and in particular to an ultraviolet laser marking device based on visual inspection. Background Technology

[0002] In the field of precision manufacturing, ultraviolet laser marking has become a core technology for marking and tracing products such as electronic components, medical devices, and automotive precision parts due to its advantages of small heat-affected zone and high marking accuracy. Ultraviolet laser marking equipment with stable processing and accurate detection functions is a key piece of equipment to ensure consistency in mass production and product quality. Among these factors, the stability of workpiece clamping, surface cleanliness, and the degree of automation of post-processing inspection and classification directly affect marking accuracy and production efficiency. Therefore, integrated and automated ultraviolet laser marking systems have become an important direction for industry development.

[0003] Currently, the industry has widely adopted basic equipment including vibration feeding, mechanical handling, indexing plate conveying, laser marking, and visual inspection, providing a basic solution for the automated production of ultraviolet laser marking. In conventional processing scenarios, it can realize orderly feeding of workpieces, batch marking, and preliminary quality inspection, effectively reducing the cost of manual intervention. Some equipment is also equipped with tooling fixtures to fix the workpieces. The workpiece surface is pretreated by cleaning process, and the finished product and waste product classification and collection structure is used to complete the basic closed loop of the processing flow, meeting the needs of most small and medium batch production.

[0004] Existing UV laser marking equipment relies heavily on independent motors and cylinders for additional driving force when clamping workpieces, increasing manufacturing costs and energy consumption. Furthermore, after the degreasing unit completes the workpiece degreasing, the resetting process requires separate stroke control, which may cause misalignment with the indexing plate station switching. This results in the degreasing process affecting the time it takes for the workpiece to be sent to the next process. Post-processing waste cleaning often requires independent air blowing or dust suction units, which not only increases the space occupied by the equipment, but also makes waste collection and gas recycling usually independent settings, lacking synchronization, which to some extent affects the overall production efficiency. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing vision-based ultraviolet laser marking equipment, the present invention is proposed.

[0007] Therefore, the problem that this invention aims to solve is that when clamping workpieces, it often relies on additional driving forces such as independent motors and cylinders, which increases the manufacturing cost and energy consumption of the equipment. Furthermore, after the degreasing component completes the degreasing of the workpiece, the resetting process requires separate control of the stroke. The cleaning of waste chips after processing often requires the configuration of independent blowing or dust suction components, which not only increases the space occupied by the equipment, but also the waste chip collection and gas recycling are usually set up independently, lacking synchronization.

Detailed Implementation

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, referring to Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a vision-based ultraviolet laser marking device. The vision-based ultraviolet laser marking device includes a marking component 1 and a tooling component 2. By setting the marking component 1 and the tooling component 2, the entire process of workpiece automatic feeding, precise positioning, laser marking, quality inspection, finished product unloading and scrap removal can be realized without frequent manual intervention. The downward pressure during the workpiece picking and placing process is used as the driving source to automatically clamp the workpiece. It can also automatically wipe and remove oil before marking. Before the workpiece is unloaded, air is blown on one side and air is drawn on the other side to clean and collect the waste generated by laser marking on the workpiece surface, which greatly improves the overall processing efficiency.

[0041] Specifically, the marking component 1 includes a first processing table 11, a vibrating feeding component 12 fixed to the top of the first processing table 11, a second processing table 13 fixed to one side of the first processing table 11, an indexing plate rotating component 15 fixed to the top of the second processing table 13, a feeding and conveying component 14 fixed to one side of the top of the second processing table 13, a laser marking component 16 fixed to one side of the feeding and conveying component 14, a visual inspection component 17 fixed to one side of the laser marking component 16, a discharging and conveying component 18 fixed to one side of the visual inspection component 17, and a waste discharge and conveying component 19 fixed to one side of the discharging and conveying component 18. The discharging and conveying component 18 and the waste discharge and conveying component 19 have the same structure.

[0042] By setting up the vibrating feeder 12, the materials can be sorted and transported to the designated picking position in an orderly manner, avoiding the tediousness and positioning deviation of manual feeding, and facilitating the normal operation of subsequent automated processes.

[0043] The vibrating feeder 12 is a vibrating feeder and a dual-channel vibrating plate, used to vibrate feed the workpiece 25 to achieve diversion and synchronous supply of the workpiece 25. The working principle of this part is existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0044] By setting the unloading and conveying component 18, the locking component 26 of the tooling assembly 2 can be unlocked simultaneously when the unlocking trigger rod 182 is pressed down while the qualified workpiece 25 is being gripped, thus achieving an automatic unlocking effect.

[0045] Specifically, the tooling assembly 2 is located on the top of the indexing plate rotating component 15, including a tooling shell 21 fixed to the top of the indexing plate rotating component 15. The tooling shell 21 has workpiece grooves 22 on both sides of its top. The tooling shell 21 has driving components 23 on both sides of its top. The driving component 23 has a locking component 26 on one side. The tooling shell 21 has ventilation components 27 on both sides of its inner cavity bottom. The tooling shell 21 has a fixed degreasing component 24 on both sides of its inner cavity. The workpiece 25 is placed inside the workpiece groove 22. The ventilation component 27 has an air supply component 28 on its top.

[0046] By setting the indexing plate rotating component 15, the tooling assembly 2 can be driven to rotate precisely at a fixed angle, and the workpiece 25 can be transported to the marking, inspection, and unloading stations in sequence, ensuring the alignment accuracy between each station and the workpiece 25 and improving the processing stability.

[0047] By setting up the laser marking component 16, the workpiece 25 can be marked with high precision using ultraviolet laser, with a small heat-affected zone, avoiding damage to the workpiece surface and meeting the marking requirements of precision parts.

[0048] By setting up the visual inspection component 17, the marking quality of the workpiece 25 can be automatically detected after marking, quickly distinguishing between qualified and unqualified products, replacing manual inspection, and improving the efficiency and accuracy of judgment.

[0049] By setting the air exchange component 27, the gas stored in the airbag 272 can be compressed when the pressure plate 236 is pressed down, so as to provide an air source for the fixing component 243 and the degreasing component 246. At the same time, the third spring 273 is used to realize the automatic reset of the airbag 272, ensuring the continuity of the air supply.

[0050] Example 2, refer to Figures 3-16 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0051] Specifically, it also includes a waste collection box 110 fixed on one side of the waste handling component 19, a material unloading and handling component 18 with a material unloading and distributing trough 111 fixed below one side, a finished product box 112 fixed at the discharge end of the material unloading and distributing trough 111, a positioning hole 211 opened at the bottom of the workpiece groove 22, a material loading and handling component 14 including a material loading gripper 141 fixed to the top of the second processing table 13, a drive trigger rod 142 fixed at the bottom of the material loading gripper 141, and a material unloading and handling component 18 including a material unloading gripper 181 fixed to the top of the second processing table 13, an unlocking trigger rod 182 fixed at the bottom of the material unloading gripper 181.

[0052] Both the loading gripper 141 and the unloading gripper 181 include a cylinder bracket, a cylinder, and a mechanical gripper. The mechanical gripper is driven by the cylinder to clamp the workpiece 25. The working principle of this part is existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0053] By matching the waste handling component 19 with the waste collection box 110, and the material distribution trough 111 with the finished product box 112, unqualified workpieces 25 and qualified workpieces 25 can be collected separately, avoiding mixing and ensuring the accuracy of product classification.

[0054] By setting the workpiece groove 22 and the positioning hole 211, the workpiece 25 can be quickly embedded into the tooling shell 21 and centered, thus avoiding the workpiece 25 from shifting its marking position during subsequent marking processes and affecting the marking effect.

[0055] Specifically, the driving component 23 includes a driving rod 231 slidably connected to the top of the tooling housing 21. The surface of the driving rod 231 is provided with a spiral groove 232. A small gear 234 is sleeved on the outer ring of the driving rod 231. A steel ball 233 is movably connected to the inner ring of the small gear 234. The steel ball 233 is slidably connected to the inner wall of the spiral groove 232. The bottom of the small gear 234 is rotatably connected to the inner wall of the tooling housing 21. A slot 235 is provided on the surface of the driving rod 231. A pressure plate 236 is fixed to the bottom of the driving rod 231. A round hole 237 is provided on the surface of the pressure plate 236.

[0056] By setting the driving component 23, when the driving rod 231 is pressed down, it can drive the spiral groove 232 on its surface to move downward, thereby driving the steel ball 233 to rotate along the spiral groove 232, thereby driving the small gear 234 to rotate, and achieving the effect of driving the large gear 244 to rotate.

[0057] By setting up the loading and conveying component 14, the drive component 23 of the tooling assembly 2 can be driven synchronously by the drive trigger rod 142 while gripping the workpiece 25, thereby providing both downward pressure and rotational force without the need for an additional power source.

[0058] By setting the drive component 23, the downward pressure of the loading gripper 141 can be converted into the axial movement of the drive rod 231 and the rotational power of the pinion 234, eliminating the need for an additional motor drive, reducing energy consumption and equipment costs. At the same time, the smooth transmission of power is achieved through the cooperation of the spiral groove 232 and the steel ball 233.

[0059] Specifically, the locking component 26 includes a mounting bracket 261 fixed to the top of the inner cavity of the tooling housing 21. A locking rod 262 is movably sleeved on the surface of the mounting bracket 261. One end of the locking rod 262 is fixed with a wedge 267, and the other end of the locking rod 262 has a sliding hole 263. A torsion spring 266 is sleeved on the surface of the mounting bracket 261. One end of the torsion spring 266 is fixed to the surface of the mounting bracket 261, and the other end of the torsion spring 266 is fixed to the surface of the locking rod 262. A roller 264 is slidably connected to the inner cavity of the sliding hole 263. A pressure rod 265 is fixed to the top of the roller 264. The pressure rod 265 is slidably connected to the top of the tooling housing 21. A threshold rod 268 is fixed to one side of the roller 264.

[0060] The bottom of the threshold rod 268 is inserted into the interior of the circular hole 237. The diameter of the circular hole 237 is larger than the diameter of the threshold rod 268. By setting the circular hole 237, when the locking rod 262 moves and drives the threshold rod 268 to move down, it will not contact the pressure plate 236. This ensures that the threshold rod 268 can contact the top of the airbag 272 and trigger the preset threshold of the pressure valve 242.

[0061] By setting the slot 235, the inclined block 267 can be provided with a locking space, so that the inclined block 267 can be locked in and limit the drive rod 231.

[0062] By setting the locking element 26, after the drive rod 231 moves down, it can be locked by the wedge block 267 engaging the slot 235 to prevent the drive rod 231 from springing back and ensure the stability of the workpiece clamping. At the same time, the cooperation between the pressure rod 265 and the unlocking trigger rod 182 allows for quick unlocking and convenient operation.

[0063] Specifically, the ventilation component 27 includes a limiting shell 271 fixed to the bottom of the inner cavity of the tooling shell 21, an airbag 272 fixed in the inner cavity of the limiting shell 271, a third spring 273 fixed in the inner cavity of the airbag 272, and a pressure plate 236 slidably connected to the inner wall of the limiting shell 271.

[0064] By setting a third spring 273, the airbag 272 can rebound after the pressure is lost, thereby driving the airbag 272 to automatically reset.

[0065] The total torque of the torsion spring 266 is greater than the total elastic force of the third spring 273, which enables the wedge block 267 to be engaged inside the third spring 273 so that the drive rod 231 will not return to its original position.

[0066] Specifically, the fixed degreasing component 24 includes an air outlet pipe 241 fixed to the bottom of the airbag 272, a pressure valve 242 fixed to the outer ring of the air outlet pipe 241, a fixing component 243 provided at one end of the air outlet pipe 241, and large gears 244 rotatably connected to both sides of the inner cavity of the tooling housing 21, with a buffer reset component 245 provided on the top of the large gears 244.

[0067] By setting up a meshing structure between the large gear 244 and the small gear 234, the rotational power of the small gear 234 can be transmitted to the large gear 244, thereby driving the buffer reset component 245 and the degreasing component 246 to move, and automatically degreasing the surface of the workpiece 25 during rotation.

[0068] Specifically, the fixing component 243 includes a first annular tube 2431 fixed to one end of the air outlet pipe 241. A piston cylinder 2432 is fixed to the inner ring of the first annular tube 2431. A piston rod 2433 is slidably connected to the inner cavity of the piston cylinder 2432. A clamping plate 2435 is fixed to one end of the piston rod 2433. A first spring 2434 is sleeved on the outer ring of the piston rod 2433. One end of the first spring 2434 is fixed to the surface of the piston rod 2433, and the other end of the first spring 2434 is fixed to the inner wall of the piston cylinder 2432.

[0069] By setting the fixing member 243, the gas discharged from the airbag 272 can push the piston rod 2433 to extend, so that the clamping plate 2435 clamps the workpiece 25 from the outer ring of the workpiece groove 22, realizing the automatic clamping of the workpiece 25. The first spring 2434 can drive the piston rod 2433 to reset after the gas is discharged, making it easier to remove the workpiece 25.

[0070] Specifically, the buffer reset component 245 includes a housing 2451 fixed to the top of the large gear 244. The top of the housing 2451 has a moving hole 2452. The inner cavity of the housing 2451 is fixed with a second spring 2453. The top of the tooling shell 21 has an arc-shaped hole 210. The top of the inner cavity of the tooling shell 21 and the two ends of the arc-shaped hole 210 are respectively fixed with a first baffle 29 and a second baffle 212.

[0071] By setting a buffer reset component 245, when the large gear 244 rotates, the moving tube 2466 can be moved along the arc-shaped hole 210 via the housing 2451. Simultaneously, the elasticity of the second spring 2453 provides buffering. After exhaust, the second spring 2453 rebounds, accelerating the reset speed of the moving tube 2466. Furthermore, the movement of the moving tube 2466 controls the opening and closing of the first one-way valve 2467. When the second baffle 212 contacts and pushes the valve stem of the first one-way valve 2467, the first one-way valve 2467... When 67 is opened, gas can be discharged from the moving pipe 2466 and blown out from the blowing pipe 2465. When the second baffle 212 contacts and pushes the valve stem of the first one-way valve 2467, the first one-way valve 2467 closes. At this time, gas cannot be discharged from the moving pipe 2466 and no blowing is performed. This achieves the effect of not blowing when the moving pipe 2466 moves and blowing when the moving pipe 2466 resets, so that the degreasing component 246 can blow the waste on the surface of the workpiece 25 during the reset process.

[0072] Specifically, the surface of the fixing component 243 is provided with an oil removal component 246. The oil removal component 246 includes an inclined tube 2461 fixed to the surface of the first ring tube 2431. One end of the inclined tube 2461 is fixed with a moving tube 2466. The outer ring of the moving tube 2466 is fitted with a first one-way valve 2467. One end of the moving tube 2466 is fixed with a slider 2468. The other end of the moving tube 2466 is fixed with an arc-shaped shell 2462. One side of the inner cavity of the arc-shaped shell 2462 is fixed with a filter screen 2463. One end of the inner side of the arc-shaped shell 2462 is fixed with a dust suction hood 2464. The other end of the inner side of the arc-shaped shell 2462 is fixed with an air blowing pipe 2465. The bottom of the arc-shaped shell 2462 is fixed with an oil removal cotton 2469.

[0073] The oil removal cotton 2469 is a microfiber cleanroom cloth. By setting microfiber cleanroom cloth as the material of the oil removal cotton 2469 of the oil removal part 246, it can quickly absorb cutting oil, rust-preventive oil and other oil stains on the surface of the workpiece 25 by means of the high specific surface area of ​​microfiber and oleophilic modification treatment.

[0074] Specifically, the air supply component 28 includes an air supply pipe 281 fixed to the top of the airbag 272. A second one-way valve 282 is fixed to the surface of the air supply pipe 281. One end of the air supply pipe 281 is connected to a second ring pipe 283. An air inlet pipe 284 is fixed to the outer ring of the second ring pipe 283. One end of the air inlet pipe 284 is fixed to the surface of the arc-shaped shell 2462. The air inlet end of the air inlet pipe 284 is located outside the filter screen 2463.

[0075] Both the inclined tube 2461 and the air inlet tube 284 are telescopic hoses, which can extend and retract during the rotation of the oil removal component 246, so that it is not affected by the fixation of the first ring tube 2431, ensuring that the oil removal component 246 can rotate normally, and the clamping plate 2435 and the first ring tube 2431 will not rotate with the rotation of the inclined tube 2461.

[0076] Example 3, referring to Figures 3-16 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0077] Specifically, the clamping plate 2435 is located on the outer ring of the inner cavity of the workpiece groove 22, and the large gear 244 is the same as the center of the workpiece groove 22. The clamping plate 2435 is made of highly elastic anti-slip rubber material, which can not only prevent scratches on the surface of the workpiece 25 during clamping, but also prevent the workpiece 25 from rotating or shifting by increasing friction, thus ensuring clamping stability and avoiding damage to the surface of the workpiece 25 during clamping.

[0078] Specifically, the slider 2468 is slidably connected to the inner wall of the housing 2451, and the surface of the moving tube 2466 is slidably connected to the inner wall of the moving hole 2452.

[0079] By setting the slider 2468, the moving tube 2466 can be stably supported, so that it can move stably by sliding on the inner wall of the outer shell 2451 through the slider 2468.

[0080] Specifically, one end of the second spring 2453 is fixed to the surface of the slider 2468, and the surface of the moving tube 2466 is slidably connected to the inner wall of the arc-shaped hole 210. The sliding arrangement of the moving tube 2466 can ensure stable movement inside the arc-shaped hole 210 and avoid jamming.

[0081] In use, the workpiece 25 to be processed is placed inside the vibrating feeder 12. The vibrating feeder 12 conveys the workpiece 25 to the picking position in an orderly manner through vibration. The feeding gripper 141 of the feeding and conveying component 14 moves to transport the workpiece 25 into the workpiece slot 22 of the top tooling assembly 2 of the indexing plate rotating component 15, so that the bottom of the workpiece 25 is inserted into the positioning hole 211 for center positioning.

[0082] When the workpiece 25 is placed into the workpiece slot 22, the drive trigger rod 142 on the loading gripper 141 moves down accordingly. Its downward pressure drives the drive component 23 to move. The drive rod 231 of the drive component 23 drives the pressure plate 236 to squeeze the air bag 272 of the ventilation component 27 downward. The gas in the air bag 272 enters the fixing component 243 through the air outlet pipe 241, pushing the clamping plate 2435 to clamp and fix the workpiece 25.

[0083] During the downward movement of the drive rod 231 on the drive member 23, the steel ball 233 inside the pinion 234 rolls in the spiral groove 232 on the surface of the drive rod 231, thereby driving the pinion 234 to rotate. The pinion 234 then drives the large gear 244 to rotate, which in turn drives the buffer reset member 245 to rotate, and then drives the moving tube 2466 to rotate. This causes the moving tube 2466 to rotate inside the arc-shaped hole 210. When the moving tube 2466 moves to the middle position of the arc-shaped hole 210, the moving tube... When the tube 2466 moves to its maximum distance, the degreasing component 246 moves above the workpiece 25, so that the bottom of the degreasing cotton 2469 contacts the top of the workpiece 25. Through horizontal rotation, the bottom of the degreasing cotton 2469 automatically wipes the top of the workpiece 25 to remove oil. Then, the pinion 234 of the drive component 23 continues to rotate. When the moving tube 2466 moves to the other end of the arc-shaped hole 210, the drive component 23 moves to its maximum distance, and the degreasing component 246 moves away from above the workpiece 25.

[0084] At this time, the inclined block 267 of the locking component 26 is precisely engaged in the slot 235 to limit the drive rod 231, preventing the drive rod 231 from resetting upwards. Then, the indexing plate rotating component 15 rotates, driving the tooling assembly 2 containing the workpiece 25 to move below the laser marking component 16. The laser marking component 16 starts and performs ultraviolet laser marking on the workpiece 25 located at the marking position according to the preset parameters. Then, it continues to rotate, driving the tooling assembly 2 containing the workpiece 25 to move below the vision inspection component 17. The vision inspection component 17 inspects the marking quality of the workpiece 25 to determine whether it is a qualified product.

[0085] If it is a qualified product, the indexing plate rotating component 15 sends it to the bottom of the unloading and conveying component 18. The unloading and conveying component 18 operates, and the workpiece 25 is taken out from the workpiece slot 22 by the unloading gripper 181 and placed into the unloading and distributing slot 111, and finally falls into the finished product box 112. If it is a defective product, the indexing plate rotating component 15 sends it to the waste discharge and conveying component 19. The waste discharge and conveying component 19 operates, takes out the workpiece 25 and puts it into the waste collection box 110.

[0086] When the unloading and conveying component 18 and the waste discharge and conveying component 19 press down, they drive the unlocking trigger rod 182 to move downward, thereby pressing the pressure rod 265 downward. This causes the roller 264 to drive one end of the locking rod 262 to press down, causing the other end of the locking rod 262 to rotate around the mounting bracket 261 and tilt upward, causing the inclined block 267 to tilt upward and move out of the slot 235. At this time, the drive rod 231 is unrestrained, causing the third spring 273 to reset and drive the drive rod 231 to reset upward. The drive rod 231 drives the pinion 234 to reset, thereby causing the large gear 244 to drive the relevant components of the fixed degreasing component 24 to reset synchronously. When the locking rod 262 is located at one end of the roller 264 and presses down, it will drive the threshold rod 268 to slightly squeeze the airbag 272 downward, causing the internal pressure of the airbag 272 to rise and reach the preset threshold of the pressure valve 242. The pressure valve 242 opens, allowing the gas inside the airbag 272 to be discharged.

[0087] Gas is discharged into the first ring pipe 2431 through the exhaust pipe 241, then enters the moving pipe 2466 through the inclined pipe 2461, and is discharged into the arc-shaped shell 2462. It is then blown onto the surface of the workpiece 25 from the blowing pipe 2465, blowing up the tiny waste chips generated by marking. At this time, the third spring 273 rebounds and drives the air bag 272 to expand and generate negative pressure, so that the air bag 272 enters the air replenishment state. Under the action of negative pressure, the blown waste chips are sucked into the arc-shaped shell 2462 from the dust suction hood 2464, filtered by the filter screen 2463, and then the air enters the air bag 272 in sequence from the air inlet pipe 284, the second ring pipe 283 and the second one-way valve 282 to replenish the air, thereby achieving the chip removal effect.

[0088] During the handling of workpiece 25, the unloading gripper 181 of the unloading transport component 18 or the waste discharge transport component 19 is positioned above workpiece 25. The unloading gripper 181 is activated to clamp workpiece 25, and then the unloading transport component 18 or the waste discharge transport component 19 transports workpiece 25, dropping it into the finished product box 112 and the waste collection box 110 respectively. When the unloading transport component 18 and the waste discharge transport component 19 clamp workpiece 25 and move it upward, the unlocking trigger rod 182 moves upward, the pressure rod 265 loses pressure, and the torsion spring 266 resets, thereby driving the locking component 26 to reset. At this time, all the above components have been reset, and workpiece 25 has completed one process. Then the above steps are repeated for laser marking operation.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
