The process flow is continuous without waiting, effectively solving the problem of low production efficiency of the original process.

[0017] (2) The welding quality is stable and consistent. The manual hand-held welding gun operation method is abandoned. The work station is equipped with a special fixed welding device. The welding posture, running trajectory and welding parameters are uniform and controllable, which completely eliminates the welding instability defects caused by shaking and uneven force of manual hand-held operation. With the material loading height setting device, the height benchmark of the front end of the product is uniformly calibrated, avoiding welding defects caused by height deviation from the clamping source. The welding forming effect of batch products is uniform.

[0018] (3) Pre-welding interception of defects reduces processing waste.

[0019] (4) The detection is accurate and objective, reducing missed detections and misjudgments. The whole process size control is achieved through dual CCD vision detection before and after welding. The workpiece clamping status and the size deviation of the finished product after welding are automatically determined. Compared with manual visual inspection, the detection accuracy is higher and the judgment standard is unified, eliminating the problem of subjective misjudgment and missed detection.

[0020] (5) Automated sorting facilitates quality traceability. The unloading station is equipped with a material sorting and unloading device, which can automatically separate good and bad products into different material boxes, eliminating manual sorting steps and reducing manual intervention. The separate collection of bad products facilitates subsequent defect statistics and process traceability, and improves the product quality control system.

[0021] (6) Reduce the intensity of manual labor and reduce human error. The whole set of equipment integrates positioning, detection, welding and sorting automation functions, which greatly reduces manual clamping, hand welding, manual quality inspection and manual sorting operations, reduces various size, welding and sorting errors caused by manual operation, and reduces the manpower input of the post.

[0027] The turntable mechanism 2 is surrounded by a circular arrangement of a loading station, a pre-welding inspection station, a welding station, a post-welding inspection station, and an unloading station. In this embodiment, five clamping fixtures 3 are respectively set on the turntable mechanism 2 for each of the five stations.

[0028] A height-fixing device 4 is installed at the loading station to fix the height of the front end of the product. A pre-welding CCD detection device 5 is installed at the pre-welding inspection station to determine whether the product on the clamping fixture 3 has any positional deviation and whether its height is within the allowable deviation range of the welding process. A welding device 6 is installed at the welding station to weld the front end of the product. A post-welding CCD detection device 7 is installed at the post-welding inspection station to determine whether the relevant dimensions of the product after welding meet the product's deviation requirements. An unloading device 8 is installed at the unloading station to unload defective and good products into different material boxes.

[0029] like Figure 6 and 7 As shown, the clamping fixture 3 includes a clamping base plate 301. The bottom of the clamping base plate 301 is fixed to the turntable mechanism 2. A slide block 302 is provided on the top of the clamping base plate 301. The slide block 302 is provided with a fixing block 303 and a slider 304. The fixing block 303 is fixedly connected to the slide block 302, and the slider 304 is slidably connected to the slide block 302. The fixing block 303 and the slider 304 are arranged horizontally. The fixing block 303 is provided with two vertically arranged fixed jaws 305, and the slider 304 is provided with two vertically arranged movable jaws 306. The movable jaws 306 and the fixed jaws 305 correspond one-to-one. The upper movable jaw 306 cooperates with the fixed jaw 305 to clamp the front end E of the product, and the lower movable jaw 306 cooperates with the fixed jaw 305 to clamp the rear end C of the product.

[0030] A movable plate 307 is provided on one side of the slide block 302. The movable plate 307 is slidably connected to a pre-reserved guide hole on the slide block 302. The movable plate 307 is fixedly connected to the slider 304. An elastic element 308 is provided on the side of the slider 304 away from the movable plate 307. One end of the elastic element 308 abuts against the slider 304, and the other end abuts against the slide block 302. In use, pushing the movable plate 307 moves the slider 304 away from the fixed block 303, thereby causing the movable gripper 306 to open. When the movable plate 307 is released, the slider 304 returns to its original position under the action of the elastic element 308, which can be a spring.

[0031] In this embodiment, a third auxiliary support plate 309 is fixed to the lower part of the clamping base plate 301. A third limiting groove 310 is provided at the supporting end of the third auxiliary support plate 309. After the product is clamped and fixed by the clamping fixture 3, the stainless steel inner tube B of the product is located in the third limiting groove 310. The third limiting groove 310 is used to limit the stainless steel inner tube B of the product to the left and right.

[0032] The height-fixing device 4 includes a height-fixing base plate 401. A height-fixing cylinder 402 is mounted on the top of the height-fixing base plate 401, located above the clamping fixture 3. The telescopic end of the height-fixing cylinder 402 faces downwards, and a limiting head 403 is installed on the telescopic end of the height-fixing cylinder 402. A height-limiting groove 404 is provided at the bottom of the limiting head 403. When the height-fixing device 4 is working, after the worker places the product into the loading station, the height-fixing cylinder 402 extends downwards. The worker then places the front end E of the product against the height-limiting groove 404 at the bottom of the limiting head 403. Then, the clamping fixture 3 clamps and fixes the product, and the height-fixing cylinder 402 returns to its original position. The height-fixing device 4 ensures that the product is placed at a consistent height.

[0033] like Figure 8 As shown, the pre-welding CCD inspection device 5 and the post-welding CCD inspection device 7 have the same structural hardware, but different built-in software, thus achieving different functions.

The opening of the first limiting groove 1005 faces the third limiting groove 310. When the gripper on the first gripper cylinder 1003 clamps and fixes the stainless steel inner tube B, the first limiting groove 1005 is used to limit the stainless steel inner tube of the product to the left and right.

[0036] Assuming the pre-welding CCD inspection device 5 is OK, the servo system lowers the linear slide 601 to drive the welding torch 603 to a suitable height. Before welding, the first slide cylinder 1002 of the auxiliary fixture 10 moves to bring the first gripper cylinder 1003 closer to the stainless steel inner tube B of the product. The grippers on the first gripper cylinder 1003 hold and fix the stainless steel inner tube B. The first gripper cylinder 1003, together with the first limiting groove 1005, the third limiting groove 310, the first gripper cylinder 1003, and the clamping fixture 3, work together to ensure the absolute position of the product during the welding process.
