Abstract
Description
Technical Field
[0001] This invention relates to the field of stainless steel water cup processing technology, and more specifically to a processing device for stainless steel water cups. Background Technology
[0002] Stainless steel water cups often require welding of the cup body during the production process.
[0003] Traditional welding methods rely heavily on manual labor or semi-automatic equipment. However, problems remain, such as the tendency for manual placement of cups to introduce deviations, leading to misaligned welds, affecting weld quality and aesthetics. Furthermore, different cup sizes require manual adjustment of the welding head position, making it difficult to ensure consistent defocusing and resulting in unstable welding effects. While some automated welding equipment has emerged, such as mechanically clamping and fixing cups or using servo motors to drive the welding head, these devices still have limitations: the clamping mechanism is typically fixed and cannot adapt to different cup sizes; weld alignment relies on preset programs and cannot detect and fine-tune the cup angle in real time; and the welding head's movement trajectory is limited, making it impossible to achieve oscillating welding to improve weld formation.
[0004] Therefore, we propose a processing device for stainless steel water cups. Summary of the Invention

[0009] Preferably, the driving assembly includes multiple T-shaped arc grooves on the upper end of the arc frame, each T-shaped arc groove has a T-shaped block fixedly connected to its inner wall, the upper ends of the multiple T-shaped blocks are fixedly connected to a driving ring, the inner wall of the T-shaped arc groove and the T-shaped blocks are fixedly connected to a spring, the upper end of the driving ring has multiple limiting grooves, and the side wall of the hollow L-shaped rod is slidably connected to the inner wall of the limiting groove.
[0010] Preferably, the drive assembly further includes an arc-shaped gear fixedly connected to the side wall of the drive ring, and an arc-shaped rack that cooperates with the arc-shaped gear is fixedly connected to the upper end of the support platform.

[0015] Preferably, the upper end of the welding platform is equipped with a feeding device for feeding stainless steel water cups.
[0016] Compared with existing technologies, the advantages of this invention are: 1. The driving component drives the positioning plate to clamp the water cup. At the same time, the conductive positioning rod extends and retracts with the change of the water cup diameter, changing the resistance value of the resistor sleeve connected to the circuit, thereby adjusting the repulsive force of the electromagnet on the magnetic block. This allows the laser welding head to automatically adjust the distance between itself and the surface of the water cup. Regardless of the water cup diameter, a constant defocus amount can be maintained, ensuring stable welding energy and improving welding consistency and quality.
[0017] 2. A vision sensor scans the surface of the water cup in real time to detect the relative position of the weld and the laser welding head. If there is a deviation, the arc-shaped magnetic block is driven to clamp and rotate the water cup step by step by intermittently switching the magnetic spring and electromagnet on and off until the weld is aligned with the welding axis. This process is precise and reliable, avoiding errors caused by manual adjustment.
[0018] 3. During the welding process, the electric push rod drives the laser welding head to move up and down, while the mounting rod slides along the corrugated groove. Under the action of the spring, the welding head produces a small lateral swing, so that the heat and molten metal are evenly distributed, avoiding the bulge in the middle of the weld and the depression on both sides, resulting in a weld with a flat surface and smooth transition, improving the structural strength and aesthetics.
[0019] 4. The feeding device can realize the automatic conveying and filling of water cups. The welding platform drives the water cups through the feeding, welding and unloading stations in turn by intermittent rotation. It works with the discharge port on the support platform to realize automatic unloading, which greatly improves production efficiency and reduces manual intervention. Attached Figure Description

[0022] 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.
[0023] Reference Figures 1-11 A processing device for stainless steel water cups includes a welding table 1 and a welding mechanism for welding stainless steel water cups. A feeding device 41 for feeding stainless steel water cups is installed on the upper end of the welding table 1. The feeding device 41 consists of a feeding track, a feeding rail, a hydraulic cylinder, and a push plate. The extension of the hydraulic cylinder causes the push plate to push the stainless steel water cups in the feeding track out for feeding. Subsequently, the stainless steel water cups arranged in the feeding rail will fall into the feeding track. This is existing technology and will not be described in detail here.
[0024] The welding mechanism includes a mounting rail 2 fixedly connected to the upper end of the welding table 1. A slider 3 is slidably connected to the inner wall of the mounting rail 2. A groove 4 is formed on the side wall of the slider 3. A magnetic block 5 is slidably connected to the inner wall of the groove 4. A groove 6 is formed on the side wall of the magnetic block 5. A mounting rod 7 is slidably connected to the inner wall of the groove 6. A laser welding head 8 is fixedly connected to one end of the mounting rod 7. A servo motor 9 is fixedly connected to the upper end of the welding table 1. A fixed shaft 10 is fixedly connected to the output end of the servo motor 9. A welding frustum 1 is fixedly connected to the side wall of the fixed shaft 10. 1. The side wall of the welding truncated cone 11 has four mounting slots 28. Each mounting slot 28 has an arc-shaped frame 12 fixedly connected to its inner wall. Multiple hollow L-shaped rods 13 are slidably connected to the side wall of the arc-shaped frame 12. A conductive positioning rod 14 is slidably connected to the inner wall of the hollow L-shaped rod 13. A positioning plate 15 is fixedly connected to one end of the conductive positioning rod 14. A spring 16 is fixedly connected between the inner wall of the hollow L-shaped rod 13 and the conductive positioning rod 14. A drive assembly for moving the hollow L-shaped rod 13 is installed on the arc-shaped frame 12.
[0025] The upper end of the welding table 1 is fixedly connected to the support platform 42 by a fixed column. The upper end of the support platform 42 is in contact with the lower end of the welding truncated cone 11, and the upper end of the support platform 42 is provided with a discharge port 40.
[0026] The welding mechanism also includes a resistor sleeve 17 fixedly embedded in the inner wall of the hollow L-shaped rod 13, an electromagnet 18 fixedly connected to the inner wall of the slide 4, a spring 19 fixedly connected between the inner wall of the slide 4 and the magnetic block 5, a conductive block 20 fixedly connected to the inner wall of the mounting groove 28, a conductive block 21 that cooperates with the conductive block 20 fixedly connected to the upper end of the support platform 42, and the conductive positioning rod 14, resistor sleeve 17, electromagnet 18, conductive block 20, conductive block 21 and external power supply are electrically connected by wires.
[0027] The drive assembly includes multiple T-shaped arc grooves 22 formed on the upper end of the arc frame 12. Each T-shaped arc groove 22 has a T-shaped block 23 fixedly connected to its inner wall. The upper ends of the multiple T-shaped blocks 23 are fixedly connected to a drive ring 25. A spring 24 is fixedly connected between the inner wall of the T-shaped arc groove 22 and the T-shaped blocks 23. The upper end of the drive ring 25 has multiple limiting grooves 26. The side wall of the hollow L-shaped rod 13 is slidably connected to the inner wall of the limiting groove 26.
[0028] The drive assembly also includes an arc-shaped gear 27 fixedly connected to the side wall of the drive ring 25, and an arc-shaped rack 29 that cooperates with the arc-shaped gear 27 is fixedly connected to the upper end of the support platform 42.
[0029] Furthermore, the stainless steel water cup is fed into the mounting groove 28 by the feeding device 41. Then, the servo motor 9 is started, which drives the fixed shaft 10 to rotate, thereby driving the welding disc 11 to rotate 90 degrees. During the rotation, the arc gear 27 in the mounting groove 28 adjacent to the laser welding head 8 will rotate and mesh with the arc rack 29. At this time, the rotation of the arc gear 27 will drive the drive ring 25 to rotate. The rotation of the limiting groove 26 on the drive ring 25 will cause the hollow L-shaped rod 13 to move closer to the stainless steel water cup, thereby driving multiple positioning plates 15 to fit with the stainless steel water cup and pushing the stainless steel water cup towards the center of the mounting groove 28, thereby positioning the stainless steel water cup and preparing it for welding.
[0030] It is worth mentioning that when the hollow L-shaped rod 13 moves, the positioning plate 15 comes into contact with the surface of the stainless steel cup. As the hollow L-shaped rod 13 continues to move, the conductive positioning rod 14 moves closer to the inner wall of the mounting groove 28, thus compressing the spring 16. For stainless steel cups of different sizes, the larger the diameter of the cup, the closer the conductive positioning rod 14 is to the inner wall of the mounting groove 28. Consequently, the resistance of the resistor sleeve 17 connected to the circuit increases, resulting in a smaller current flowing into the electromagnet 18. This, in turn, reduces the magnetic field of the electromagnet 18. The smaller the magnetic repulsion generated by block 5, the closer block 5 will be to electromagnet 18 under the action of spring 2 19, thus causing the laser welding head 8 to move away from the stainless steel cup. Conversely, if the diameter of the stainless steel cup is smaller, the laser welding head 8 will move closer to the stainless steel cup. Therefore, the position of the laser welding head 8 can be dynamically adjusted according to the diameter of the stainless steel cup, so that the straight-line distance between the laser welding head 8 and the surface of the stainless steel cup is equal regardless of the size of the stainless steel cup, thereby ensuring that the defocusing amount remains unchanged and the welding effect is guaranteed.
[0031] An electric push rod 30 is fixedly connected to the bottom of the mounting rail 2, and the movable end of the electric push rod 30 is fixedly connected to the slider 3.
[0032] A rotating mechanism is installed on the positioning plate 15. The rotating mechanism includes a T-shaped arc groove 33 on the side wall of the positioning plate 15. A hollow block 34 is slidably connected to the inner wall of the T-shaped arc groove 33. A magnetic spring 35 is fixedly connected between the hollow block 34 and the inner wall of the T-shaped arc groove 33. The magnetic spring 35 is existing technology and can contract after being energized. An arc-shaped magnetic block 36 is slidably connected to the inner wall of the hollow block 34. An electromagnet 37 is fixedly connected to the inner wall of the hollow block 34. A spring 38 is fixedly connected between the inner wall of the hollow block 34 and the arc-shaped magnetic block 36.
[0033] The rotating mechanism also includes a vision sensor 39 fixedly connected to the upper end of the mounting rail 2. The vision sensor 39, the magnetic spring 35, and the electromagnet 37 are connected by a controller.
[0034] Furthermore, after the stainless steel cup is centered and positioned, the vision sensor 39 scans the surface of the stainless steel cup to detect whether the joint of the stainless steel cup to be welded is on the same axis as the laser welding head 8. If they are not on the same axis, the vision sensor 39 sends a signal to the controller to supply intermittent current to the magnetic spring 35 and the electromagnet 37. The magnetic spring 35 contracts when current is applied and extends when power is cut off. The electromagnet 37 synchronously and intermittently generates magnetic repulsion, causing the arc-shaped magnetic block 36 to intermittently clamp the stainless steel cup. When the magnetic spring 35 contracts, it drives the hollow block 34 to slide on the inner wall of the T-shaped arc groove 33, thereby moving the arc-shaped magnetic block 36. Since the arc-shaped magnetic block 36 and the stainless steel cup are in close contact at this time... When the surfaces of the cups are in close contact, the curved magnetic block 36 will cause the stainless steel cup to rotate at a certain angle. After the power is turned off, the magnetic spring 35 extends, and at this time, the curved magnetic block 36 will retract into the hollow block 34 under the action of the spring 38, no longer in contact with the surface of the stainless steel cup. Then, the hollow block 34 will move back to its original position under the action of the magnetic spring 35. At this time, the stainless steel cup will not rotate. When the power is turned on again, the stainless steel cup will rotate at a certain angle again. This process repeats until the joint on the surface of the stainless steel cup rotates to be on the same axis as the laser welding head 8. At this time, the vision sensor 39 scans and stops supplying intermittent current to the magnetic spring 35 and the electromagnet 37. The stainless steel cup will then remain still, waiting for welding.
[0035] The mounting rail 2 is fixedly connected to the side wall of the limiting plate 31. The side wall of the limiting plate 31 is provided with a wave groove 32. The side wall of the mounting rod 7 is slidably connected to the inner wall of the wave groove 32. The inner wall of the groove 6 is fixedly connected to the guide rod 43. The side wall of the guide rod 43 is slidably connected to the mounting rod 7. Two springs 44 are symmetrically sleeved on the side wall of the guide rod 43. The two ends of the two springs 44 are fixedly connected to the inner wall of the groove 6 and the side wall of the mounting rod 7, respectively.
[0036] Furthermore, by reciprocating the electric push rod 30 once, the slider 3 moves downward and then upward to reset, causing the magnetic block 5 to move downward and then upward to reset. The magnetic block 5, through the mounting rod 7, then drives the laser welding head 8 to move downward and then upward to reset, thus welding the joint of the stainless steel water cup. During welding, because the mounting rod 7 slides against the inner wall of the wave groove 32, under the action of the spring 44, the mounting rod 7 moves in a wave-like motion along the wave groove 32, causing the laser welding head 8 to move in a wave-like motion. This allows the laser welding head 8 to produce a small left-right swaying motion, which widens the weld seam and prevents the arc heat and molten metal from concentrating too much in the middle, causing a bulge in the middle of the weld seam while the sides, where it meets the base material, become concave due to insufficient heat. The left-right swaying welding allows the heat and molten metal to be evenly distributed over a wider area, resulting in a smooth, rounded weld seam with higher welding quality.
[0037] Furthermore, after welding is completed, the servo motor 9 drives the welding platform 11 to rotate 90 degrees. At this time, the welded stainless steel cup will rotate 90 degrees to the next position. During the rotation, the arc-shaped rack 29 will separate from the arc-shaped gear 27, and the drive ring 25 will rotate in the opposite direction to reset under the action of the spring 24. At this time, the hollow L-shaped rod 13 will also drive the positioning plate 15 to move outward, no longer clamping and fixing the stainless steel cup. When the stainless steel cup moves to the discharge port 40, it will fall into the collection box below through the discharge port 40, thus collecting the welded stainless steel cup. The welding position will then repeat the above welding process for the next stainless steel cup. This process can be repeated to achieve automated and continuous stainless steel cup welding.
[0038] In this invention, a stainless steel water cup is fed into the mounting groove 28 by a feeding device 41. Then, a servo motor 9 is started, which drives the fixed shaft 10 to rotate, thereby driving the welding frustum 11 to rotate 90 degrees. During the rotation, the arc gear 27 in the mounting groove 28 adjacent to the laser welding head 8 will rotate and mesh with the arc rack 29. At this time, the rotation of the arc gear 27 will drive the drive ring 25 to rotate. The rotation of the limiting groove 26 on the drive ring 25 will cause the hollow L-shaped rod 13 to move closer to the stainless steel water cup, thereby driving multiple positioning plates 15 to fit against the stainless steel water cup and pushing the stainless steel water cup towards the center of the mounting groove 28, thereby positioning the stainless steel water cup and preparing it for welding.
[0039] When the hollow L-shaped rod 13 moves, the positioning plate 15 comes into contact with the surface of the stainless steel cup. As the hollow L-shaped rod 13 continues to move, the conductive positioning rod 14 moves closer to the inner wall of the mounting groove 28, thus compressing the spring 16. For stainless steel cups of different sizes, the larger the diameter of the cup, the closer the conductive positioning rod 14 is to the inner wall of the mounting groove 28. Consequently, the resistance of the resistor sleeve 17 connected to the circuit increases, resulting in a smaller current flowing into the electromagnet 18. This, in turn, causes the electromagnet 18 to exert a force on the magnetic block 5. The smaller the magnetic repulsion, the closer the magnetic block 5 will be to the electromagnet 18 under the action of the spring 2 19, thus causing the laser welding head 8 to move away from the stainless steel cup. Conversely, if the diameter of the stainless steel cup is smaller, the laser welding head 8 will move closer to the stainless steel cup. Therefore, the position of the laser welding head 8 can be dynamically adjusted according to the diameter of the stainless steel cup, so that the straight-line distance between the laser welding head 8 and the surface of the stainless steel cup is equal regardless of the size of the stainless steel cup, thereby ensuring that the defocusing amount remains unchanged and the welding effect is guaranteed.
[0040] Once the stainless steel cup is centered, the vision sensor 39 scans the surface of the cup to detect whether the seam to be welded is on the same axis as the laser welding head 8. If not, the vision sensor 39 sends a signal to the controller to supply intermittent current to the magnetic spring 35 and electromagnet 37. The magnetic spring 35 contracts when current is applied and extends when power is cut off. The electromagnet 37 then synchronously generates intermittent magnetic repulsion, causing the arc-shaped magnetic block 36 to intermittently clamp the stainless steel cup. When the magnetic spring 35 contracts, it causes the hollow block 34 to slide along the inner wall of the T-shaped arc groove 33, thereby moving the arc-shaped magnetic block 36. Since the arc-shaped magnetic block 36 is now aligned with the surface of the stainless steel cup... When the surfaces are tightly pressed together, the arc-shaped magnetic block 36 will cause the stainless steel cup to rotate at a certain angle. After the power is turned off, the magnetic spring 35 extends, and at this time, the arc-shaped magnetic block 36 will retract into the hollow block 34 under the action of the spring 38, no longer pressing against the surface of the stainless steel cup. Then, the hollow block 34 will move back to its original position under the action of the magnetic spring 35. At this time, the stainless steel cup will not rotate. When the power is turned on again, the stainless steel cup will rotate at a certain angle again. This process repeats until the joint on the surface of the stainless steel cup rotates to be on the same axis as the laser welding head 8. At this time, the vision sensor 39 scans and stops supplying intermittent current to the magnetic spring 35 and the electromagnet 37. As a result, the stainless steel cup will remain still, waiting for welding.
[0041] By reciprocating the electric push rod 30 once, the slider 3 moves downward and then upward to reset, causing the magnetic block 5 to move downward and then upward to reset. The magnetic block 5, through the mounting rod 7, then drives the laser welding head 8 to move downward and then upward to reset, thus welding the joint of the stainless steel water cup. During welding, because the mounting rod 7 slides against the inner wall of the wave groove 32, under the action of the spring 44, the mounting rod 7 moves in a wave-like motion along the wave groove 32, causing the laser welding head 8 to move in a wave-like motion. This allows the laser welding head 8 to produce a small left-right swaying motion, which widens the weld seam and prevents the arc heat and molten metal from concentrating too much in the middle, causing a bulge in the middle of the weld seam while the sides, where it meets the base material, become concave due to insufficient heat. The left-right swaying welding allows the heat and molten metal to be evenly distributed over a wider area, resulting in a smooth, rounded weld seam with higher welding quality.
[0042] After welding is completed, the servo motor 9 drives the welding platform 11 to rotate 90 degrees. At this time, the welded stainless steel cup will rotate 90 degrees to the next position. During the rotation, the arc-shaped rack 29 will separate and mesh with the arc-shaped gear 27. Then, the drive ring 25 will rotate in the opposite direction and reset under the action of the spring 24. At this time, the hollow L-shaped rod 13 will also drive the positioning plate 15 to move outward, no longer clamping and fixing the stainless steel cup. When the stainless steel cup moves to the discharge port 40, it will fall into the collection box below through the discharge port 40, thus collecting the welded stainless steel cup. The welding position will then repeat the above welding process for the next stainless steel cup. This process can be repeated to achieve automated and continuous stainless steel cup welding.
