[0001] This utility model relates to the field of laser processing technology, specifically to a visual positioning laser processing device. Background Technology

[0002] Visual positioning laser processing technology is a key technology in modern manufacturing. It achieves precise control of laser processing equipment through a high-precision vision system to meet the ever-increasing demands for product quality and personalization. This technology combines the advantages of machine vision and laser processing, providing precise cutting, welding, and marking services in various fields such as automotive manufacturing, aerospace, and electronics. With advancements in image processing algorithms and laser equipment, visual positioning laser processing technology plays a vital role in improving processing accuracy, reducing material waste, and increasing production efficiency.

[0003] Chinese utility model patent CN208772740U discloses a vision-positioning laser cutting machine, including a frame and a servo control system. The frame includes a movable frame and a fixed frame. The movable frame is equipped with a Y-axis motion device and a Z-axis motion device. A laser cutting mechanism is located below the Z-axis motion device. X-axis motion motors are located at both ends of the movable frame. An X-axis transmission gear is located at the front end of the shaft of the X-axis motion motor. The X-axis transmission gear cooperates with an X-axis rack on the fixed frame to form an X-axis transmission device.

[0004] Existing laser processing equipment places the workpiece directly on the surface of the processing table for laser processing. However, placing the workpiece directly on the surface of the processing table can easily cause misalignment and displacement, which will affect the subsequent laser processing of the workpiece. Furthermore, during laser positioning operations, there may be a positional deviation between the positioning position and the ideal center position, resulting in a decrease in the positioning accuracy of the workpiece. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to facilitate the stable processing of laser processing equipment with better visual positioning in the later stage, so as to clamp and limit the workpieces of different thicknesses and avoid misalignment and displacement; and to realize multi-directional cutting processing of workpieces, which facilitates more precise laser positioning operation and plays a role in precise visual positioning.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A visual positioning laser processing device includes a base, on which a plurality of columns are arranged, the plurality of columns being located at the upper top corner of the base, a support plate being fixed on the plurality of columns, and a positioning processing mechanism being arranged below the support plate;

[0008] A processing table is fixed on the base. The processing table has a through groove inside and is slidably connected to the placement plate. Two telescopic cylinders are fixed on the base and are located inside the processing table. The output end of the telescopic cylinders is fixedly connected to the placement plate. Guide rails are provided on both sides of the processing table on the base, and clamping mechanisms are provided on the guide rails.

[0009] As a further embodiment of this utility model, the positioning and processing mechanism includes a rotating disk, a fixed block, a first motor, a first screw, a sliding block, and a laser processing head.

A sliding groove is formed at the bottom of the rotating disk, and the first screw is rotatably disposed in the sliding groove. The output shaft of the first motor passes through the fixed block and is fixed to one end of the first screw. A sliding block is threadedly connected to the first screw, and the sliding block is slidably disposed in the sliding groove. A laser processing head is disposed at the bottom of the sliding block.

[0010] As a further embodiment of this utility model, the clamping mechanism includes a U-shaped guide rail slider, a mounting platform, a slot, a fixing plate, a second screw, and a pressure plate. The U-shaped guide rail slider is slidably disposed on the guide rail, and a mounting platform is fixed to the top of the U-shaped guide rail slider. A slot is opened on the side of the mounting platform facing the processing table. The second screw passes through the top of the mounting platform and is disposed in the slot. A fixing plate is fixed to the side of the mounting platform facing the processing table. A pressure plate is slidably disposed in the slot. The pressure plate is threaded through the second screw.

[0016] As a further embodiment of this invention, a wide-angle camera is provided at the bottom of the rotating disk.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) When in use, place the workpiece on the feeding table. The workpiece will enter the placement plate in the processing table through the opening. At this time, the telescopic cylinder is activated by the external control panel, so that the placement plate rises and drives the workpiece to rise. After the workpiece rises to the clamping mechanism, the clamping mechanism slides to one side through the guide rail, so that the clamping mechanism and the workpiece cooperate with each other. Then, the second screw is rotated, which drives the pressure plate set on the second screw to move downward. The workpiece is fixed by the fixing plate and the pressure plate, which makes it easier for the laser processing equipment with vision positioning to be used stably in the later stage. Thus, workpieces of different thicknesses can be clamped and limited to avoid misalignment and displacement.

[0019] (2) When performing laser processing, start the second motor to drive the rotating disk to rotate, so that the laser processing head is close to the part to be cut. Then start the second motor to drive the sliding block on the first screw to move in the groove, thereby driving the laser processing head to move. This can realize multi-directional cutting processing of the workpiece, which is convenient for more precise laser positioning operation. The wide-angle camera is easy to identify the position and shape of the workpiece, improve the cutting accuracy, and play the role of precise visual positioning. Attached Figure Description

[0029] Please see the appendix Figure 1-5A visual positioning laser processing device includes a base 10, on which a plurality of columns 11 are provided, the plurality of columns 11 being located at the upper top corner of the base 10, a support plate 12 being fixed on the plurality of columns 11, and a positioning processing mechanism being provided below the support plate 12.

[0030] A processing table 17 is fixed on the base 10. The processing table 17 has a through groove inside and is slidably connected to the placement plate 20. Two telescopic cylinders 19 are fixed on the base 10 and are located inside the processing table 17. The output ends of the telescopic cylinders 19 are fixedly connected to the placement plate 20. Guide rails 15 are provided on both sides of the processing table 17 on the base 10. Clamping mechanisms 30 are provided on the guide rails 15. Limiting plates 16 are fixed at both ends of the guide rails 15. The limiting plates 16 are used to limit the clamping mechanisms 30.

[0031] A feeding platform 14 is provided on one side of the processing table 17 on the base 10. An opening 18 is provided on the side of the processing table 17 near the feeding platform 14. A second motor 13 is provided at the top center of the support plate 12. The output shaft of the second motor 13 passes through the support plate 12 and is fixed to the rotating disk 21.

[0032] When in use, the workpiece is placed on the feeding table 14 and enters the placement plate 20 inside the processing table 17 through the opening 18. At this time, the telescopic cylinder 19 is activated through the external control panel, which causes the placement plate 20 to rise and drive the workpiece to rise, thereby improving the stability of the workpiece inside the processing table 17.

[0033] The positioning and processing mechanism includes a rotating disk 21, a fixed block 22, a first motor 23, a first screw 24, a sliding block 25, and a laser processing head 26. The rotating disk 21 is rotatably mounted at the center of the lower part of the support plate 12. The fixed block 22 is fixed to the outer side of the rotating disk 21. The first motor 23 is fixed to the fixed block 22. A groove is formed at the bottom of the rotating disk 21, and the first screw 24 is rotatably mounted within the groove. The output shaft of the first motor 23 passes through the fixed block 22 and is fixed to one end of the first screw 24. The sliding block 25 is threaded onto the first screw 24 and slides within the groove. The laser processing head 26 is mounted at the bottom of the sliding block 25. A wide-angle camera 27 is mounted at the bottom of the rotating disk 21. The wide-angle camera 27 facilitates the identification of the workpiece's position and shape, improving cutting accuracy and serving a visual positioning function.

[0034] When performing laser processing, the second motor 13 is started, which drives the rotating disk 21 to rotate, so that the laser processing head 26 is close to the part to be cut. Then the second motor 23 is started, which drives the sliding block 25 on the first screw 24 to move in the groove, thereby driving the laser processing head 26 to move. This can realize multi-directional cutting processing of the workpiece, which facilitates more precise laser positioning operation and plays a role in precise visual positioning.

[0035] The clamping mechanism 30 includes a U-shaped guide rail slider 31, a mounting platform 32, a slot 33, a fixing plate 34, a second screw 35, and a pressure plate 36. The U-shaped guide rail slider 31 is slidably mounted on the guide rail 15. The mounting platform 32 is fixed to the top of the U-shaped guide rail slider 31. The mounting platform 32 has a slot 33 on the side facing the processing table 17. The second screw 35 passes through the top of the mounting platform 32 and is located in the slot 33.

The pressure plate 36 is threaded through the second screw 35. The fixing plate 34 and the pressure plate 36 have the same dimensions.

[0036] After the workpiece is raised to the clamping mechanism 30, the clamping mechanism 30 is slid to one side via the guide rail 15, so that the clamping mechanism 30 and the workpiece cooperate with each other. Then, the second screw 25 is rotated, which drives the pressure plate 36 set on the second screw 25 to move downward. The workpiece is fixed by the fixing plate 34 and the pressure plate 36, so that workpieces of different thicknesses can be clamped and limited to avoid misalignment. Then, laser processing can be performed.

[0037] Working principle:

[0038] In use, the workpiece is placed on the unloading table 14, and it enters the placement plate 20 inside the processing table 17 through the opening 18. At this time, the telescopic cylinder 19 is activated via the external control panel, causing the placement plate 20 to rise and lift the workpiece. After the workpiece rises to the clamping mechanism 30, the clamping mechanism 30 is slid to one side via the guide rail 15, allowing the clamping mechanism 30 to engage with the workpiece. Then, the second screw 25 is rotated, causing the pressure plate 36 on the second screw 25 to move downwards. The workpiece is fixed by the fixing plate 34 and the pressure plate 36, thus allowing for the processing of different thicknesses. The workpiece is clamped and limited to prevent misalignment and displacement. Then, laser processing can be performed. The second motor 13 is started, which drives the rotating disk 21 to rotate, so that the laser processing head 26 is close to the part to be cut. Then the second motor 23 is started, which drives the sliding block 25 on the first screw 24 to move in the groove, thereby moving the laser processing head 26. This can realize multi-directional cutting processing of the workpiece, which facilitates more precise laser positioning operation. The wide-angle camera 27 is set to facilitate the identification of the position and shape of the workpiece, improve the cutting accuracy, and play a role in precise visual positioning.

[0039] Finally, it should be noted that the telescopic cylinder, motor, laser processing head, wide-angle camera, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
