Description

Technical Field

[0001] This utility model relates to the field of blue light welding positioning technology, and in particular to a high-precision blue light welding positioning fixture. Background Technology

[0002] Blue light welding positioning technology belongs to the field of optical measurement and precision positioning. Its core is to project laser or structured light in the blue light band onto the workpiece surface, and combine it with a high-precision imaging system and algorithm analysis to achieve micron-level position and attitude positioning. High-precision blue light welding positioning fixtures are intelligent equipment based on the above technology. They use blue light sensors to dynamically monitor workpiece position deviations and combine closed-loop control to adjust the attitude of the welding torch or workpiece to achieve sub-millimeter-level positioning accuracy.

[0003] However, in the existing technology, some blue light welding devices have problems such as low workpiece flipping efficiency and the need for repeated clamping. Specifically, after the workpiece has completed welding on one side, due to the lack of a multi-degree-of-freedom rotation mechanism, the workpiece needs to be removed from the fixture and repositioned and clamped before the reverse or side welding operation can be carried out. This further prolongs the production cycle of loading and unloading operations and reduces the efficiency of workpiece welding.

[0004] Therefore, a high-precision blue light welding positioning fixture is proposed to address the above problems. Utility Model Content

Detailed Implementation

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

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a high-precision blue light welding positioning fixture, including a base plate 1. A working plate 2 is fixedly connected to the top of the base plate 1. The base plate 1 and the working plate 2 form the most basic support base of the entire device. A welding assembly is fixedly connected to the top of the working plate 2. The welding assembly includes a robotic arm 3. The bottom end of the robotic arm 3 is fixedly connected to the top of the working plate 2, where the working plate 2 provides stable support for the robotic arm 3. A laser welder 4 is fixedly connected to one end of the robotic arm 3. A blue light detector 5 is fixedly connected to one side of the laser welder 4. The welder 4 can complete the welding operation of the workpiece, while the blue light detector 5 can make fine adjustments to the laser welder 4 according to the deviation of the current position of the workpiece to ensure the quality of the welding. A drive assembly is fixedly connected to the top front side of the work plate 2. The drive assembly includes a cylinder 6. The bottom end of the cylinder 6 is fixedly connected to the top front side of the work plate 2. The work plate 2 here provides stable support for the cylinder 6. A push plate 7 is fixedly connected to the drive end of the cylinder 6. The bottom end of the push plate 7 is slidably connected to the top of the work plate 2. After the cylinder 6 is started, it can drive the push plate 7 to move back and forth.

[0034] A slide plate 8 is fixedly connected to the rear of the drive assembly. The front of the slide plate 8 is fixedly connected to the rear of the push plate 7. The push plate 7 drives the slide plate 8 to move synchronously. The bottom ends of two slide plates 8 are slidably connected to the top of the work plate 2. Another slide plate 8 is fixedly connected to the top of the work plate 2. Two clamping plates 9 are rotatably connected to the inner wall of the slide plate 8. When the slide plate 8 moves, it drives the clamping plates 9 to move. An arc ring 10 is fixedly connected to the outside of the clamping plate 9. The outside of the arc ring 10 is slidably connected to the inner wall of the slide plate 8. Because of the presence of the arc ring 10, the clamping plate 9... The slide plate 8 can rotate on its inner wall. A rubber frame 11 is fixedly connected to the inner wall of the clamping plate 9. The rubber frame 11 is used to clamp the workpiece while preventing damage to its surface. Insert pins 12 are fixedly connected to the front side of the two clamping plates 9. The two clamping plates 9 are fixed to the work plate 2. A ball clamp 13 is fixedly connected to the front end of the insert pin 12. Multiple sliding pins 14 are slidably connected to the inner wall of the other two clamping plates 9. The clamping plates 9 here are movable clamping plates 9 pushed by the push plate 7, and the clamping plates 9 here provide a stable sliding space for the sliding pins 14.

[0035] The ball 13 is externally slidably connected to the inner wall of another clamping plate 9. A card 15 that engages with the ball 13 is fixedly connected to the inner side of the sliding column 14. When the movable clamping plates 9 (the pair moved by the push plate 7) move towards the fixed clamping plates 9 (the pair fixed to the working plate 2), the insert 12 and the ball 13 gradually insert into the interior of the sliding clamping plate 9. Multiple springs 16 are installed inside the other two clamping plates 9. One end of each spring 16 is fixedly connected to one end of the sliding column 14, and the other end of the spring 16 is fixedly connected to... On the inner wall side of the other clamping plate 9, when the ball 13 is inserted into the interior of the movable clamping plate 9, the spring 16 here will be compressed and contracted, generating a reaction force. Then, after the ball 13 is fully inserted, this force is released, thereby cooperating with multiple cards 15 to fix it, ensuring the connection between the movable clamping plate 9 and the fixed clamping plate 9. At this time, the laser welder 4 can be controlled to perform welding operations on the workpiece. When it is necessary to flip the workpiece, simply rotate the clamping plate 9, which will rotate under the action of the arc ring 10, and then continue to weld the joint.

[0036] Reference Figure 1 , Figure 4 and Figure 5 A suction device 17 is fixedly connected to the rear side of the laser welder 4. The suction device 17 can absorb the exhaust gas generated during laser welding. A hose 18 is fixedly connected to one end of the suction device 17. The hose 18 is used to transport exhaust gas. A mounting ring 19 is rotatably connected to the other end of the hose 18. A threaded tube 20 is fixedly connected to the other side of the mounting ring 19. An exhaust gas box 21 is connected to the external thread of the threaded tube 20. The threaded tube 20 can connect the hose 18 and the exhaust gas box 21 together.

[0037] One side of the mounting ring 19 contacts the outside of the exhaust gas box 21, and the bottom of the exhaust gas box 21 contacts the top of the working plate 2. The inner wall of the exhaust gas box 21 is detachably connected to a filter plate 22. A valve 23 is installed on the outside of the exhaust gas box 21. After the exhaust gas enters the exhaust gas box 21 which has been pre-filled with purifying agent, it is purified. After the impurities are separated, they are intercepted by the filter plate 22. Then, the valve 23 is opened to discharge the clean and harmless air. After a period of time, the adhesion of the internal filter plate 22 can be observed through the observation window at the top of the exhaust gas box 21. When cleaning is required, the box cover is opened and the filter plate 22 is pulled out. If you want to perform deep cleaning of the exhaust gas box 21, you can also directly pull the exhaust gas box 21 up from the bottom plate 1.

[0038] Working Principle: During operation, the workpiece is placed in a clamping mechanism consisting of a fixed clamping plate 9 and a movable clamping plate 9. The rubber frame 11 liner cushions the clamping force to prevent surface damage. The cylinder 6 in the drive assembly pushes the push plate 7, causing the slide plate 8 and movable clamping plate 9 to move towards the fixed clamping plate 9. When the insert pin 12 is inserted into the sliding clamping plate 9, the locking ball 13 and the locking plate 15 are self-locked by the spring force of the spring 16, ensuring the clamping plate 9 is securely closed. The blue light detector 5 monitors the workpiece position deviation in real time and feeds the data back to the control system. The robotic arm 3 then adjusts its posture and uses the laser welder 4 to perform high-precision welding. During welding, the suction device 17 introduces waste gas into the waste gas box 21 through the hose 18. After impurities are filtered and analyzed by the internal purifier, the waste gas is adsorbed by the filter plate 22, and finally, clean air is discharged. The valve 23 controls the opening and closing of the discharged gas, and the observation window facilitates the inspection of the filter plate 22 and the waste gas box 21, allowing for timely judgment on whether cleaning is necessary.

[0039] After welding on one side is completed, the workpiece is flipped over by rotating the clamping plate 9. The arc ring 10 structure allows the clamping plate 9 to rotate flexibly within the inner wall of the slide plate 8, enabling welding operations on the other three sides without disassembling the workpiece. Meanwhile, the exhaust gas box 21 and the hose 18 feature a quick-release design with threaded pipes 20, allowing for periodic cleaning of the filter plate 22 or complete replacement, ensuring efficient exhaust gas treatment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
