Description

Technical Field

[0001] The invention relates to the technical field of thin-wall stainless steel pipe production, and in particular to a laser welding production line for thin-wall stainless steel pipe production. Background Art

[0002] Thin-walled stainless steel pipe refers to a stainless steel pipe with a ratio of wall thickness to outer diameter of no more than 6%, and the wall thickness is usually between 0.6mm and 4.0mm. This type of pipe is lightweight and beautiful due to its thin wall thickness, and is widely used in water supply and drainage systems, gas transmission, and architectural decoration. In the production and processing of thin-walled stainless steel pipes, it is usually necessary to go through the processes of raw material preparation, steel plate uncoiling, hot rolling, thin-walled pipe welding, surface treatment, and quality inspection in sequence to complete the production of thin-walled stainless steel pipes. In the processing process of thin-walled pipe welding, it is necessary to use a laser welding production line to weld the rolled tubular stainless steel sheets to ensure the sealing and stability of the pipe. In the process of welding thin-walled stainless steel pipes on the laser welding production line in the prior art, if there are defects on the surface of the stainless steel pipe before welding or the parts to be welded are not in a straight line, since there is no relevant automatic detection mechanism inside the production line, the stainless steel pipe to be welded cannot be pre-detected and processed, so the laser welding production line will continue to weld the defective stainless steel pipe, resulting in a significant reduction in the yield rate of the stainless steel pipe during the production process, and indirectly leading to an increase in the production cost of the stainless steel pipe for the enterprise.

[0032] In this embodiment, the first industrial camera 17, the second industrial camera 23 and the third industrial camera 31 are all industrial matrix cameras of model I3CMOS05000KMB provided by Tupu Optoelectronics in the prior art.

[0033] In the present invention, when the user uses the device, the stainless steel pipe body 2 is formed after the previous several processes. Figure 1 As shown, with the help of multiple conveying rollers 4 at the left end, the stainless steel pipe body 2 is conveyed toward the direction close to the laser welding equipment 10. When the stainless steel pipe body 2 continues to move from the bottom of the laser welding equipment 10 toward the right end, the welding head at the bottom end of the laser welding equipment 10 can automatically perform laser welding on the welding parts of the curled stainless steel pipe body 2, and with the help of multiple conveying rollers 4 at the right end, the welded stainless steel pipe body 2 is conveyed toward the next processing equipment, and the stainless steel pipe body 2 continues to be processed subsequently.

[0034] The multiple conveying rollers 4 at the left end convey the curled stainless steel pipe body 2 toward the right end and conduct trial welding, so as to facilitate the debugging of the laser welding equipment 10 to a suitable state and ensure the subsequent continuous welding of the stainless steel pipe body 2. After the laser welding equipment 10 welds the right end of the stainless steel pipe body 2 to a specified length, the multiple conveying rollers 4 and the laser welding equipment 10 can be controlled to stop working together, and then the two second sliders 21 are controlled to move upward to a specified height inside the corresponding second slide groove 19, and then the limit plate 20 is controlled to rotate 180 degrees clockwise between the two second sliders 21, driving the storage groove 26 at the top of the limit plate 20 to rotate to the bottom, and the two first sliders 18 are controlled to move toward the moving plate close to the moving plate. 7, driving the two moving rods 6 and the limiting plate 20 and other components to move and adjust in the direction close to the moving plate 7, until the limiting plate 20 moves to a position close to the laser welding equipment 10. At this time, since the limiting plate 20 is rotated 180 degrees, the first mounting plate 22 and the baffle plate 24 originally located on the left side of the limiting plate 20 are rotated to the right end, and after the two moving rods 6 are moved and adjusted on the top of the bottom plate 1, the baffle plate 24 can be driven to move to the bottom of the laser welding equipment 10, so that the baffle plate 24 can cover the welding head at the bottom of the laser welding equipment 10, so as to avoid the switch of the laser welding equipment 10 being accidentally touched by humans, so that the welding head at the bottom continues to emit laser, causing damage to the components inside the production line; Then, the telescopic ends of the two second electric telescopic rods 28 are controlled to extend together, driving the cutting knife 27 to extend downward from the inside of the storage groove 26, and automatically cutting the stainless steel pipe body 2 below. In conjunction with the cutting groove opened on the top of one of the support blocks 12, the part of the stainless steel pipe body 2 after trial welding can be automatically cut off, and the cut parts are manually inspected and analyzed, and then the relevant parameters of the laser welding equipment 10 are adjusted, so as to make adequate preparations for the subsequent continuous laser welding of the stainless steel pipe body 2 and ensure that the welding quality of the stainless steel pipe body 2 meets the requirements.

[0035] At the same time, when the laser welding equipment 10 formally performs continuous laser welding on the stainless steel pipe body 2, the multiple first industrial cameras 17 arranged inside the fixing frame 5 and the second industrial camera 23 at the bottom of the first mounting plate 22 cooperate with each other to automatically perform visual inspection on the appearance quality of the stainless steel pipe body 2 and the part to be welded. When the stainless steel pipe body 2 to be welded passes through the circular cavity enclosed by one of the support blocks 12 and the limit plate 20, the impurities attached to its surface can be automatically scraped off by the limit plate 20 and one of the support blocks 12. In addition, by means of the downward rotation adjustment of the blow head 25, the blow head 25 can automatically clean the impurities attached to the welding part of the stainless steel pipe body 2 to be welded, so as to facilitate the subsequent automatic welding process of the stainless steel pipe body 2 by the laser welding equipment 10, and can also indirectly improve the welding quality of the stainless steel pipe body 2.

[0036] If multiple first industrial cameras 17 detect that the appearance quality of the stainless steel tube body 2 to be welded has defects, or the second industrial camera 23 detects that the welding parts of the stainless steel tube body 2 to be welded are not on the same straight line, in order to prevent the production line from continuing to produce the defective stainless steel tube body 2, the first industrial camera 17 and the second industrial camera 23 can transmit the relevant detection information to the controller, and the controller can control the entire production line to suspend operation. At this time, the laser welding equipment 10 no longer needs to continue welding the subsequent defective stainless steel tube body 2, and can repeat the above steps to cut the stainless steel tube body 2, and separate the stainless steel tube body 2 with no defects in the front section and after laser welding from the stainless steel tube body 2 with defects in the rear section and not after laser welding, so as to avoid the production line continuing to operate, producing and preparing unqualified stainless steel tube bodies 2, and increasing production costs.

[0037] Furthermore, before the above-mentioned cutting of the stainless steel pipe body 2, at this time, since the limit plate 20 is rotated 180 degrees and adjusted, the blowing head 25 at the left end is driven to rotate to the right end and is located above the first mounting plate 22. When the baffle 24 blocks the welding head at the bottom of the laser welding equipment 10, the blowing head 25 can blow air toward the welding head to perform air cooling and heat dissipation treatment on the welding head, thereby accelerating the heat dissipation of the welding head. After the subsequent inspection and adjustment of the relevant equipment in the production line, the subsequent stainless steel pipe body 2 can continue to be used in the subsequent welding work of the stainless steel pipe body 2 after the visual inspection of multiple first industrial cameras 17 and second industrial cameras 23 is qualified, and the welding head after rapid heat dissipation can continue to be put into the subsequent welding work of the stainless steel pipe body 2, without waiting for the temperature of the welding head to drop before continuing the production of the stainless steel pipe body 2.

[0038] After the laser welding work of the stainless steel pipe body 2 by the laser welding equipment 10 is completed, the welding part of the stainless steel pipe body 2 is automatically visually identified and detected with the help of the third industrial camera 31. If no large impurities are detected near the welding part, one of the grinding rollers 32 close to the welding part can be directly controlled to rotate, and the welding part of the stainless steel pipe body 2 can be polished. When the polished stainless steel pipe body 2 continues to be transported toward the right end, the polished welding part can be cleaned with the help of a cleaning brush 36, and the grinding debris in the welding part can be removed. When the stainless steel pipe body 2 passes through the circular hole inside the vertical plate 9, the residual impurities attached to its outer wall are automatically scraped off by the scraper 16, so as to achieve the effect of automatic polishing and automatic cleaning of the welding part of the stainless steel pipe body 2, so as to facilitate the subsequent processing of the stainless steel pipe body 2.

[0039] If the third industrial camera 31 detects that there are large impurities in the welding area, the area where the large impurities exist in the stainless steel pipe body 2 can be moved to the inside of the ring 35, and the gear 14 of the driving motor 13 can be controlled to rotate, so that the ring 35 is driven by the gear ring 15 to rotate, and the two grinding rollers 32 are driven to rotate on the surface of the stainless steel pipe body 2, so that the two grinding rollers 32 cooperate to quickly grind and remove the large impurities on the surface of the stainless steel pipe body 2, thereby further improving the efficiency of grinding and removing impurities in the welding area of ​​the stainless steel pipe body 2.

[0040] Moreover, when the ring 35 rotates, it can also drive the cleaning brush 36 to fully clean the surface of the stainless steel pipe body 2, thereby improving the cleaning effect of the surface of the stainless steel pipe body 2 after welding; At the same time, when the scraper 16 is scraping and cleaning the impurities on the surface of the stainless steel pipe body 2, some impurities will accumulate on the surface of the scraper 16. At this time, the rotating block 37 can be controlled to rotate and adjust, driving the two third electric telescopic rods 38 and the cleaning brush 36 to rotate and adjust upward until the cleaning brush 36 rotates to a state flush with the scraper 16. The telescopic ends of the two third electric telescopic rods 38 are controlled to extend, driving the cleaning brush 36 to contact the outer wall of the scraper 16. As the ring 35 drives the cleaning brush 36 to continue to rotate, the cleaning brush 36 can clean and remove the impurities accumulated on the surface of the scraper 16, which is convenient for the subsequent use of the scraper 16.

[0041] After the laser welding work on the stainless steel pipe body 2 is completed, the telescopic ends of the two first electric telescopic rods 29 can be controlled to move upward and adjusted together until the welding head moves to a position higher than the two moving rods 6, and the two first sliders 18 are controlled to move in the direction close to the ring 35 inside the corresponding first slide groove 11, and the two second sliders 21 are controlled to drive the limit plate 20 to move upward and adjusted inside the corresponding second slide groove 19, and then the limit plate 20 is controlled to rotate 180 degrees counterclockwise. At this time, the blowing head 25 can blow air toward one of the grinding rollers 32 to clean the impurities on the surface of one of the grinding rollers 32. After the impurities attached to the surface of one of the grinding rollers 32 are cleaned, the ring 35 is controlled to rotate and adjust so that the other grinding roller 32 rotates to a position close to the blowing head 25, and the blowing head 25 can continue to clean the impurities on the surface of the other grinding roller 32, so as to facilitate the subsequent use of the two grinding rollers 32.
