Description

Technical Field

[0001] This invention relates to the field of laser marking technology, specifically to a high-precision laser marking device for die-cast housings with quality inspection function. Background Technology

[0002] The high-precision laser marking equipment for die-cast housings with quality inspection function is an industrial-grade intelligent marking device designed specifically for key die-cast housing components such as the three-electric system and chassis of new energy vehicles. Its core function is to perform non-contact laser marking on the surface of die-cast materials such as aluminum alloys with micron-level precision. At the same time, it integrates an industrial vision inspection system to achieve online full inspection after marking, and to verify the clarity, integrity, positional accuracy and data accuracy of the marking in real time. This meets the stringent requirements of the new energy vehicle industry for component marking and improves the automation level and production efficiency of the production line.

[0003] A Chinese patent with publication number CN110560915A discloses an automatic laser marking machine for automotive gearbox housings. The machine includes a worktable, an X-axis translation stage, a Y-axis translation stage, a Z-axis translation stage, a laser marking machine, and an online monitoring camera. It also includes a variable-size fixture fixed to the worktable. The variable-size fixture comprises a feeding guide rail, a slider, a base plate, a feeding cylinder, a fixing block, a clamping guide rail, a clamping block, a clamping cylinder, a positioning pin, a positioning block, a movable positioning block, and a positioning cylinder. By having the clamping cylinder push the clamping block, which cooperates with the fixing block, it can adapt to and clamp various different models of automotive gearboxes. The positioning cylinder and the movable positioning block cooperate to raise different models of automotive gearboxes to the required marking height. The base plate has multiple sets of positioning screw holes. The positioning pins and positioning blocks are fixed to the corresponding positioning screw holes of different automotive gearbox models, serving a positioning function.

[0004] Currently, the integration level of traditional die-cast shell laser marking equipment on the market is low. In the entire process of mass production of die-cast shells, whether manual loading and unloading is used or robotic arms are used to complete workpiece transfer and positioning operations, the entire set of equipment is difficult to achieve integrated continuous operation of the three processes of shell loading, high-precision laser marking, and online quality inspection. Each link is independent and the workstations are clearly separated. After a workpiece completes a process, it needs to be repeatedly transferred and clamped and positioned again. There is a lot of ineffective waiting and repetitive operation in the process connection. This not only increases the frequency of manual intervention and the motion loss of the reciprocating motion of the robotic arm, but also lengthens the complete processing cycle of a single shell. Furthermore, it is easy to cause positioning deviation due to multiple clamping. From the perspective of production process, it significantly reduces the continuous processing capacity of the entire production line and seriously restricts the overall operation efficiency and automation level of the workshop.

[0005] Therefore, the present invention provides a high-precision laser marking device for die-cast housings with quality inspection function. Summary of the Invention

[0006] The purpose of this invention is to provide a high-precision laser marking device for die-cast housings with quality inspection function, so as to solve the problems mentioned in the background art.

[0007] A high-precision laser marking device for die-cast housings with quality inspection function includes a worktable. A frame is fixedly mounted on the top of the worktable. The frame has at least three mounting sides, wherein a mounting bracket is mounted on the first mounting side, and an adjustment mechanism for adjusting the position of the mounting bracket is provided on the frame. A concave frame is fixedly mounted on the second mounting side, and a quality inspection mechanism for inspecting the die-cast housing is provided on the concave frame. A laser marking assembly is mounted on the mounting bracket. A ring frame is fixedly mounted on the top of the worktable, and the ring frame is located at the lower end of the frame. The frame is equipped with a rotating annular disk with symmetrical annular grooves. A limiting ring is engaged within the annular groove and fixedly connected to the inner wall of the annular frame. A gear ring is fixedly installed on the inner ring of the annular disk. A drive mechanism for moving the gear ring is provided inside the worktable. A clamping mechanism is provided on the annular disk. A blower cleaning assembly for cleaning the die-cast housing after marking is provided on the second mounting side of the frame. A brush cleaning assembly for pre-treating and cleaning the die-cast housing to be marked is provided on the third mounting side of the frame.

[0008] By adopting the above scheme, when performing laser marking on the surface of a die-cast shell, the die-cast shell to be processed is placed on a clamping mechanism. After the shell is fixedly clamped by the clamping mechanism, the drive mechanism moves, driving the annular disk to rotate via a gear ring. During the rotation of the annular disk, the limiting ring and the annular groove assist in the smooth rotation of the annular disk. After the annular disk rotates to a preset angle, the clamping mechanism moves, carrying the fixedly clamped die-cast shell. After the die-cast shell is moved to the processing point, the position of the mounting bracket is adjusted by the adjustment mechanism, which in turn adjusts the position of the laser marking component. Once the laser marking component is adjusted to the desired position, its movement can mark the die-cast shell. High-precision laser marking is performed. After laser marking is completed, the drive mechanism continues to move, causing the annular disk to rotate at a preset angle, moving the next shell to be processed to the processing point. At the same time, the air-blowing cleaning component moves to clean the marked shell, effectively preventing the subsequent quality inspection mechanism from affecting image acquisition. During rotation, the quality inspection mechanism can collect and upload image information, which can be compared on a computer to achieve the purpose of quality inspection. By repeating the above steps, the shell is continuously loaded, fixed, rotated, marked, cleaned, inspected, and unloaded, allowing for continuous and uninterrupted marking and loading of die-cast shells, thus improving processing efficiency.

[0009] Preferably, the adjustment mechanism includes a power motor, a threaded rod, and a guide rod. The power motor is fixed to the top of the frame.

A limit rod is fixedly disposed on the top of the concave frame, and the limit rod is engaged with the frame.

[0010] By adopting the above scheme, the movement of the power motor can drive the threaded rod to rotate, thereby adjusting the position of the mounting bracket. The guide rod can guide the mounting bracket to move smoothly, which in turn drives the laser marking component to move, enabling marking processing on the die-cast housing.

[0012] By adopting the above scheme, the laser marking device can perform marking processing on the housing, control the operation of the electric telescopic rod to adjust the position of the sliding plate, and guide the sliding plate through the guide shaft to make the sliding plate move smoothly, thereby adjusting the position of the laser marking device.

The concave frame is engaged with the sliding block, and the outer surface of the threaded screw is threadedly connected to the inside of the sliding block. The industrial camera for quality inspection of the die-cast housing is fixed at the bottom of the sliding block.

[0014] By adopting the above solution, an industrial camera can be used to capture images of the die-cast shell after marking. After being uploaded to the platform, the captured images can be compared and then quality inspection processing can be carried out. The operation of the servo motor will drive the screw to rotate, thereby adjusting the position of the sliding block, and thus adjusting the position of the industrial camera.

[0015] Preferably, the drive mechanism includes a positioning frame, a dual-output shaft motor, a power shaft, a drive wheel, and a drive gear. The positioning frame is fixed to the side of the worktable, the dual-output shaft motor is fixed inside the positioning frame, one end of the power shaft is fixedly connected to one of the output ends of the dual-output shaft motor, one end of the power shaft extends into the ring frame, the drive wheel is fixed on the power shaft, the drive gear is fixed on the power shaft, and the drive gear meshes with the gear ring.

[0016] By adopting the above scheme, the positioning frame provides installation space for the dual-output shaft motor. When the dual-output shaft motor is working, it can drive the power shaft to move. When the power shaft rotates, it will drive the drive wheel and drive gear to rotate. When the drive gear rotates, it will drive the gear ring to rotate. The gear ring can drive the ring disk to rotate.

[0017] Preferably, a fan is fixedly installed inside the workbench, and the other output end of the dual-shaft motor is connected to the impeller inside the fan. The air outlet of the fan is connected to a conveying pipe, and the other end of the conveying pipe is connected to the air blowing cleaning component.

[0018] By adopting the above scheme, the operation of the dual-output shaft motor will drive the fan to move, and the fan can deliver airflow when it moves, which can be delivered through the delivery pipe.

[0019] Preferably, the air-blowing cleaning assembly includes a diversion channel and nozzles. The diversion channel is fixed to the second mounting side of the frame, and the other end of the delivery pipe is connected to the diversion channel. The nozzle array is disposed on the diversion channel.

[0020] By adopting the above scheme, after the airflow enters the diversion tank through the delivery pipe, the airflow will be directed to one side through the nozzle. The nozzle is set at an angle and aimed at the die-cast housing, which can clean the die-cast housing.

[0021] Preferably, the clamping mechanism includes a load-bearing plate, a lifting push rod, and a clamping block. The load-bearing plate is arranged in a circular array on an annular disk. The lifting push rods are symmetrically arranged on the load-bearing plate. The clamping blocks corresponding to the lifting push rods are symmetrically arranged on the load-bearing plate, and the telescopic end of the lifting push rod is fixedly connected to the side of the clamping block.

[0022] By adopting the above scheme, when the clamping mechanism fixes the die-cast shell, after the die-cast shell is placed on the load-bearing plate, the operation of the lifting push rod will push the clamping block to move, and the movement of the clamping block can fix the die-cast shell.

[0023] Preferably, a protective groove is fixedly provided on the third mounting side of the frame, and a rotating rod is rotatably provided in the protective groove. Both ends of the rotating rod are fixedly connected to driven wheels, one of which is connected to a drive wheel via a belt drive.

[0024] By adopting the above scheme, when the drive wheel rotates, it drives the rotating rod to rotate through the driven wheel. When the rotating rod rotates, it drives another set of driven wheels to rotate synchronously. When the driven wheels rotate, they drive the round shaft to rotate through the belt pulley. When the round shaft rotates, it drives the square plate and connecting strip to rotate circumferentially. When the connecting strip rotates, it drives the brush to move circumferentially. After the brush contacts the surface of the die-cast housing, it can clean the die-cast housing, which is convenient for subsequent marking processing and ensures the marking processing effect.

[0025] Preferably, a pulley is fixedly mounted on the round shaft, and the pulley is connected to another driven pulley via a belt drive. A connecting strip is fixedly connected to the bottom end of the square plate, and a brush is connected to the bottom of the connecting strip.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. The high-precision laser marking equipment for die-cast housings with quality inspection function described in this invention facilitates continuous and uninterrupted processing of material loading, marking, and quality inspection through the setting of annular disc and clamping blocks, thereby improving work efficiency. During operation, the lifting push rod drives the clamping block to complete the displacement action, and the clamping block achieves stable positioning and clamping of the die-cast housing. The subsequent drive component drives the annular turntable to rotate smoothly in increments, with a single rotation angle being a preset angle (the preset angle range is 45 degrees to 120 degrees, and in one embodiment, the preset angle is 72 degrees). The clamping mechanism drives the clamped die-cast housing to move synchronously. After the housing is transferred to the laser processing station, the laser marking mechanism... The machine starts up and completes the marking and engraving process on the shell surface. After a single marking process is completed, the drive mechanism drives the annular turntable to rotate at a preset angle again, moving the next set of shells to be processed to the marking station. During the synchronous rotation of the turntable, the quality inspection mechanism simultaneously collects the marking images of the marked shells and uploads them to the industrial control computer. The terminal system automatically completes the image standard comparison, thereby realizing online quality inspection of workpiece markings. The equipment repeatedly performs the entire process of workpiece loading and clamping, turntable indexing and transfer, laser marking, visual quality inspection, and unloading, and can continuously and uninterruptedly complete the batch marking processing of die-cast shells, significantly optimizing the production line flow rhythm and improving the overall processing capacity and production efficiency.

[0027] 2. The high-precision laser marking equipment for die-cast housings with quality inspection function described in this invention uses brushes to pre-treat and clean the surface of the die-cast housing during the feeding stage, removing impurities and preventing contaminants from interfering with the quality of laser marking. An electric telescopic push rod drives a square plate to move horizontally, flexibly adjusting the working distance between the brush and the workpiece. When the circular shaft rotates, it drives the square plate and connecting strip to rotate synchronously, thereby driving the brush to rotate around the workpiece surface. The brush continuously rubs and cleans against the outer wall of the die-cast housing, completing a comprehensive cleaning process for the workpiece. This provides a clean and flat processing surface for subsequent laser marking processes, effectively ensuring clear and uniform marking and steadily improving the overall marking quality.

[0028] 3. The high-precision laser marking equipment for die-cast housings with quality inspection function described in this invention can perform secondary cleaning treatment on the die-cast housings after laser marking through the set fan and diversion tank, removing dust, metal shavings and other impurities attached to the workpiece surface, eliminating various adverse effects caused by impurities. The dual-shaft motor drives the fan to generate high-pressure airflow, which is transported to the diversion tank through the conveying pipeline, and then sprayed directionally by the inclined nozzles precisely aligned with the die-cast housing. The high-speed airflow thoroughly sweeps the surface of the workpiece, completing deep cleaning, effectively removing residual debris from the housing surface, preventing impurities from obscuring the marking patterns, avoiding impurities from interfering with the image acquisition clarity of the quality inspection agency, and reducing the risk of misjudgment in visual inspection.

[0029] 4. The high-precision laser marking equipment for die-cast housings with quality inspection function described in this invention sets the single rotation angle of the annular disk to a preset angle, with the preset angle range being 45 degrees to 120 degrees. In one embodiment, the preset angle is 72 degrees. This satisfies the spatial arrangement requirements of the die-cast parts on the annular disk, rationally allocates the spacing between each workstation, and allows the operator to simultaneously observe all working conditions such as feeding, marking, cleaning, and quality inspection from the first mounting side of the frame. This facilitates production monitoring and abnormal handling, and improves the ease of operation and production safety of the equipment. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8This invention provides a technical solution: a high-precision laser marking device for die-cast housings with quality inspection function, comprising a worktable 1, a frame 102 fixedly mounted on the top of the worktable 1, the frame 102 having at least three mounting sides, wherein a mounting bracket 106 is mounted on the first mounting side, and an adjustment mechanism for adjusting the position of the mounting bracket 106 is provided on the frame 102; a concave bracket 212 is fixedly mounted on the second mounting side, and a quality inspection mechanism for quality inspection of the die-cast housing is provided on the concave bracket 212; a laser marking assembly is mounted on the mounting bracket 106; and a ring frame 325 is fixedly mounted on the top of the worktable 1, and the ring frame 325 is located at the lower end of the frame 102. An annular disk 326 is rotatably mounted inside the frame 325. Symmetrical annular grooves 327 are arranged on the annular disk 326. A limiting ring 328 is engaged within the annular groove 327 and is fixedly connected to the inner wall of the annular frame 325. A gear ring 329 is fixedly mounted on the inner ring of the annular disk 326. A drive mechanism for moving the gear ring 329 is provided inside the worktable 1. A clamping mechanism is provided on the annular disk 326. A blower cleaning assembly for cleaning the die-cast housing after marking is provided on the second mounting side of the frame 102. A brush cleaning assembly for pre-treating and cleaning the die-cast housing to be marked is provided on the third mounting side of the frame 102. The preset angle range is 45 degrees to 120 degrees, and in one embodiment the preset angle is 72 degrees. By setting the single rotation angle to the preset angle, the spatial arrangement requirements of the die-cast parts on the annular disk can be met, the spacing between each station can be reasonably allocated, and the operator can observe all working conditions such as feeding, marking, cleaning, and quality inspection from the first installation side of the frame at the same time. This facilitates production monitoring and abnormal handling, and improves the ease of operation and production safety of the equipment.

[0034] When using a high-precision laser marking equipment with quality inspection function to laser mark the surface of a die-cast housing, the die-cast housing to be processed is placed on a clamping mechanism. After the housing is fixedly clamped by the clamping mechanism, the drive mechanism moves through the gear ring 329 to drive the annular disk 326 to rotate. When the annular disk 326 rotates, the limit ring 328 and the annular groove 327 help the annular disk 326 to rotate smoothly. After the annular disk 326 rotates to a preset angle, the clamping mechanism moves the fixedly clamped die-cast housing to the processing point. After the die-cast housing is moved, the position of the mounting bracket 106 is adjusted by the movement of the adjustment mechanism, which in turn adjusts the position of the laser marking component, so that the laser marking component is adjusted to the moving position. Afterwards, the laser marking component moves to perform high-precision laser marking on the die-cast housing. After laser marking is completed, the drive mechanism continues to move, causing the annular disk 326 to rotate by a preset angle, moving the next housing to be processed to the processing point. At the same time, the air-blowing cleaning component moves to clean the marked housing, effectively preventing the subsequent quality inspection agency from affecting image acquisition. During rotation, the quality inspection agency can collect and upload image information, which can be compared on a computer to achieve the purpose of quality inspection. By repeating the above steps, the housing is continuously loaded, fixed, rotated, marked, cleaned, inspected, and unloaded, allowing for continuous and uninterrupted marking and loading of die-cast housings, thus improving processing efficiency.

A limit rod 213 is fixedly disposed on the top of the concave frame 212, and the limit rod 213 is engaged with the frame 102.

[0036] The movement of the power motor 103 can drive the threaded rod 104 to rotate, thereby adjusting the position of the mounting bracket 106. The mounting bracket 106 can be guided by the guide rod 105 to move smoothly, thereby driving the laser marking component to move and perform marking processing on the die-cast housing.

[0037] When adjusting the vertical position of the quality inspection mechanism, the electric push rod 211 is controlled to work, which can adjust the position of the concave frame 212. When the concave frame 212 moves, the limit rod 213 can guide the concave frame 212 to move smoothly, thereby adjusting the position of the quality inspection mechanism.

[0038] Furthermore, the laser marking assembly includes an electric telescopic rod 107, a sliding plate 108, a guide shaft 109, and a laser marking device 110.

The concave frame 212 is engaged with the sliding block 216. The outer surface of the threaded screw 215 is threadedly connected to the inside of the sliding block 216. The industrial camera 217, used for quality inspection of the die-cast housing, is fixed to the bottom of the sliding block 216.

[0041] The industrial camera 217 can capture images of the die-cast shell after marking and processing. After uploading to the platform, the captured images can be compared and then quality inspection processing can be carried out.

The nozzles 546 are arranged in an array on the diversion channel 545.

[0047] After the airflow enters the diversion trough 545 through the delivery pipe 324, the airflow will be directed to one side through the nozzle 546. The nozzle 546 is tilted and aimed at the die-cast housing, which can clean the die-cast housing.

[0048] Furthermore, the clamping mechanism includes a load-bearing plate 330, a lifting push rod 431, and a clamping block 432. The load-bearing plate 330 is arranged in a circular array on the annular disk 326. The lifting push rod 431 is symmetrically arranged on the load-bearing plate 330. The clamping block 432, corresponding to the lifting push rod 431, is symmetrically arranged on the load-bearing plate 330. The telescopic end of the lifting push rod 431 is fixedly connected to the side of the clamping block 432.

[0049] When the clamping mechanism clamps the die-cast housing, after placing the die-cast housing on the load-bearing plate 330, the lifting push rod 431 will push the clamping block 432 to move. The movement of the clamping block 432 can clamp the die-cast housing.

[0050] Furthermore, a protective groove 433 is fixedly provided on the third mounting side of the frame 102. A rotating rod 434 is rotatably provided in the protective groove 433. Both ends of the rotating rod 434 are fixedly connected to driven wheels 435. One of the driven wheels 435 is connected to the drive wheel 321 via belt drive. A bracket 436 is fixedly provided on the frame 102. A square block 437 is fixedly provided in the bracket 436. A round shaft 438 is rotatably provided in the square block 437. A square groove 543 is provided in the round shaft 438. A square plate 440 passes through the square groove 543. An electric telescopic push rod 544 is fixedly provided in the square groove 543. The telescopic end of the electric telescopic push rod 544 is fixedly connected to the top of the square plate 440. A pulley 439 is fixedly provided on the round shaft 438. The pulley 439 is connected to another driven wheel 435 via belt drive. A connecting strip 541 is fixedly connected to the bottom of the square plate 440. A brush 542 is connected to the bottom of the connecting strip 541.

[0051] When the drive wheel 321 rotates, it drives the rotating rod 434 to rotate via the driven wheel 435. When the rotating rod 434 rotates, it drives another set of driven wheels 435 to rotate synchronously. When the driven wheels 435 rotate, they drive the circular shaft 438 to rotate via the belt pulley 439. When the circular shaft 438 rotates, it drives the square plate 440 and the connecting bar 541 to rotate circumferentially. When the connecting bar 541 rotates, it drives the brush 542 to move circumferentially. After the brush 542 contacts the surface of the die-cast housing, it can clean the die-cast housing, which is convenient for subsequent marking processing and ensures the marking processing effect. The square plate 440 can be moved by the electric telescopic push rod 544. When the square plate 440 moves, the position of the brush 542 can be adjusted to adapt to the cleaning of housings of different volumes. The brush 542 is detachable and can be replaced when impurities are adsorbed.

[0052] Working Principle: First, when using a high-precision laser marking equipment with quality inspection function to laser mark the surface of a die-cast housing, after placing the die-cast housing on the load-bearing plate 330, controlling the lifting push rod 431 will push the clamping block 432 to move. The movement of the clamping block 432 can fix and clamp the die-cast housing. After the housing is fixed and clamped, the electric telescopic push rod 544 can push the square plate 440 to move. When the square plate 440 moves, the position of the brush 542 can be adjusted. When the drive wheel 321 rotates, it will drive the rotating rod 434 to rotate through the driven wheel 435. When the rotating rod 434 rotates, it will drive another set of driven wheels 435 to rotate synchronously. When the driven wheels 435 rotate, they will drive the round shaft 438 through the belt pulley 439. When the circular shaft 438 rotates, it drives the square plate 440 and connecting strip 541 to rotate circumferentially. The rotation of the connecting strip 541 drives the brush 542 to rotate circumferentially. After the brush 542 contacts the surface of the die-cast housing, it cleans the die-cast housing, facilitating subsequent marking processing and ensuring the marking effect. When the dual-output shaft motor 219 works, it drives the power shaft 220 to move. When the power shaft 220 rotates, it drives the drive wheel 321 and drive gear 322 to rotate. The rotation of the drive gear 322 drives the gear ring 329 to rotate, which in turn drives the annular disk 326 to rotate. When the annular disk 326 rotates, the cooperation of the limiting ring 328 and the annular groove 327 assists in the smooth rotation of the annular disk 326. After the preset angle is reached, the clamping mechanism moves, carrying the fixedly clamped die-cast housing. Once the housing is moved to the processing point, the power motor 103 is controlled to rotate the threaded rod 104, thereby adjusting the position of the mounting bracket 106. The guide rod 105 guides the mounting bracket 106, ensuring its smooth movement, which in turn moves the laser marking assembly, allowing for marking processing of the die-cast housing. The laser marking device 110 then marks the housing. Controlling the electric telescopic rod 107 adjusts the position of the sliding plate 108. The guide shaft 109 guides the sliding plate 108, ensuring its smooth movement, which in turn adjusts the position of the laser marking device 110. After laser marking is completed... After completion, the drive mechanism continues to move, causing the annular disk 326 to rotate by a preset angle, moving the next shell to be processed to the processing point. The dual-shaft motor 219 drives the fan 323 to move, which delivers airflow through the delivery pipe 324. After the airflow enters the diversion groove 545 through the delivery pipe 324, the airflow is directed to one side by the nozzle 546. The nozzle 546 is tilted and aimed at the die-cast shell for cleaning. The electric push rod 211 is controlled to adjust the position of the concave frame 212. When the concave frame 212 moves, the limit rod 213 guides the concave frame 212 to move smoothly, thereby adjusting the position of the quality inspection mechanism.The industrial camera 217 captures images of the marked die-cast shell, which are then uploaded to a platform for comparison and quality inspection. The servo motor 214 drives the threaded screw 215 to rotate, adjusting the position of the sliding block 216, which in turn adjusts the position of the industrial camera 217. This allows for flexible positioning for quality inspection. During rotation, the quality inspection unit captures and uploads image information, which is then compared on a computer for quality inspection. This process is repeated, continuously loading, fixing, rotating, marking, cleaning, inspecting, and unloading the die-cast shell, allowing for continuous and uninterrupted marking and loading processes, thus improving processing efficiency.
