Description

Technical Field

[0001] This invention relates to the field of electrolyte tank processing, and in particular to an automated positioning welding system and process adapted to electrolyte tanks. Background Technology

[0002] In existing technologies, electrolyte tanks, as the core containers for electrolyte storage and transportation, are directly related to the purity and safety of the electrolyte during storage and transportation due to their manufacturing quality. The electrolyte tank is assembled from three independent components: the tank body, the upper end cap, and the lower end cap. The circumferential weld between the tank body and the upper and lower end caps is crucial to the container's sealing performance and service life. Given the small opening and limited internal space of the electrolyte tank, a single-sided welding double-sided forming process is required. However, quality control of the back-side forming during circumferential welding has always been a challenge in this process, making it difficult to guarantee the quality of the back-side forming. Furthermore, precise adjustment of the relative positions and coaxiality between the tank body, upper end cap, and lower end cap is required before welding. Existing positioning methods are mostly single-positioning, meaning only the tank body is clamped and positioned, while the positioning of the end caps often relies on manual adjustment or independent clamps, lacking an automatic positioning mechanism among the three components. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies, such as small opening and limited internal space of electrolyte tanks, difficulty in ensuring the back-side forming quality in circumferential welding, and the fact that positioning methods are mostly single positioning, this invention provides an automated positioning welding system and process adapted to electrolyte tanks.

[0009] To further explain, the barrel positioning assembly includes a second electric rotating ring fixedly connected to the base frame, a fixed cylinder fixedly connected to the rotating part of the second electric rotating ring, and two second mounting rings fixedly connected to the fixed cylinder via a connecting frame; wherein, each of the second mounting rings is circumferentially and equidistantly connected with several other guide positioning units and several other fixing units.

[0010] To further explain, the gasket assembly includes: A second electric straight-moving device is connected to the base frame. An electric rotating frame is connected to the second electric straight-moving device. The second electric straight-moving device is configured as an electric slide rail and an electric slider. A mounting tube is fixedly connected to the rotating part of the electric rotating frame. A mounting rod is inserted into the mounting tube. Several fourth electric push rods are provided on the mounting tube. The initial state of the extension and retraction ends of all the fourth electric push rods is inserted into the mounting rod. Several third electric straight-moving devices are connected to the mounting rod. There are two pad support units, each connected to the mounting rod and several third electric straight-moving devices. The mounting rod is provided with an air supply channel communicating with the mounting tube. Several exhaust holes corresponding to the two pad support units are provided on the air supply channel. An arc-shaped sealing strip is provided on both sides of each exhaust hole on the outer ring surface of the mounting rod. Several limiting strips are provided on the mounting rod. Sliding grooves matching the limiting strips are provided in the mounting tube. The two pad support units are symmetrical from left to right. The third electric straight-moving device is configured as an electric slide rail and two electric sliders.

[0011] Further explanation: The padding support unit includes a first mounting plate slidably connected to the mounting rod, several annularly distributed first connecting plates movably connected to the first mounting plate via several rotating shafts, several second connecting plates movably connected to the several first connecting plates via rotating shafts, and a second mounting plate movably connected to all the second connecting plates via several rotating shafts. The first mounting plate is a hollow structure, each first connecting plate has a vent groove, and the first mounting plate is connected to several connecting hoses, each connecting hose communicating with a vent groove of one of the first connecting plates. Each end of the first connecting plate is connected to a mounting module, and all mounting modules are jointly bonded with a high-temperature resistant flexible adhesive ring. An annular ceramic pad is bonded to the outer surface of the high-temperature resistant flexible adhesive ring, and the outer surface of the annular ceramic pad has a shaped groove.

[0012] Further explanation: The installation module includes a connector, which is detachably connected to the first connecting plate. The connector has a connecting groove that communicates with the ventilation groove. The high-temperature resistant flexible adhesive ring has several through grooves and several first air guide grooves that communicate with the connecting grooves at positions opposite to each connector.

[0013] Further explanation includes an automated positioning and welding process adapted for electrolyte tanks, comprising the following steps: Step 1: Positioning, the tank body, lower end cap, and upper end cap are placed sequentially by an external robotic arm or manually. The lower and upper end caps are automatically positioned by two end cap positioning components, and the tank body is automatically positioned by a tank body positioning component. After positioning, a gasket component supports the weld seam inside the tank body.

Step 3: Removal, after fixing, the gasket component is controlled to retract from the tank body, and finally, the fixed electrolyte tank is removed by an external material handling device.

[0014] The beneficial effects of this invention are as follows: 1. The molten metal is limited by the forming groove of the annular ceramic gasket, allowing the molten metal to flow into the groove and solidify to form a regular and full weld bead. This avoids the problem of irregular weld beads forming on the back side of the weld pool or depressions due to gravity when welding directly on one side. It ensures the quality of single-sided welding with double-sided forming and significantly reduces the post-weld repair rate.

[0015] 2. After welding is completed, the cooling plates of the part directly opposite the connecting groove and the through groove are activated. The argon gas is cooled to reduce the temperature of the stainless steel at the edge of the welding area, thereby increasing the heat dissipation rate inside the molten pool and increasing the supercooling during the solidification process of the molten pool. This results in grain refinement and improves the toughness and fatigue resistance of the weld.

[0016] 3. The second electric push rod extends to a preset length to guide the positioning guide wheel to the barrel body. The barrel body is positioned by several ring-shaped positioning guide wheels that are evenly distributed. The same operation is used to guide, position and adjust the lower end cap and the upper end cap. No manual adjustment is required for positioning, so as to realize the automatic positioning of the barrel body, the upper end cap and the lower end cap. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

The base frame 1 is connected to a plurality of first electric straighteners 802, which are divided into left and right groups. Each group of first electric straighteners 802 is connected to a head positioning assembly. The tank positioning assembly is mounted on the base frame 1 and located between two head positioning assemblies. The welding assembly is connected to the base frame 1 and is equipped with a plurality of vision sensors 7. The gasket assembly is connected to the base frame 1 and provides a gasket for the back of the weld inside the tank 002, working in conjunction with the tank positioning assembly and the two head positioning assemblies. The upper end cap 001 and the lower end cap 003 are positioned and fixed by two end cap positioning components, the barrel body 002 is positioned and fixed by the barrel body positioning component, and the upper end cap 001, the barrel body 002 and the lower end cap 003 are welded by the gasket component inside the barrel body 002 through limiting.

[0021] The welding assembly includes a mounting frame 2 fixed to the base frame 1, a plurality of electric lifters 3 connected to the mounting frame 2, a plurality of first electric push rods 4 fixed to the plurality of electric lifters 3 respectively, an electric telescopic frame 5 fixed to the telescopic ends of the plurality of first electric push rods 4 through a connecting block, and two welding guns 6 respectively connected to the two telescopic ends of the electric telescopic frame 5 through a connecting frame. The electric lifter 3 is configured with an electric slide rail and an electric slider. By controlling the electric slider to slide on the electric slide rail, it drives the first electric push rod 4 and the parts connected to it to rise and fall.

[0022] The end cap positioning assembly includes a fixed frame 801 connected to a group of first electric straight-through devices 802, a first electric rotating ring 8 fixedly connected to the fixed frame 801, a first mounting ring 9 fixedly connected to the rotating part of the first electric rotating ring 8, a plurality of guide positioning units connected to the first mounting ring 9, and a fixed unit connected to the first mounting ring 9. The fixing units are equidistantly distributed in a ring on the first mounting ring 9, and the guiding and positioning units are divided into left and right groups, with all the guiding and positioning units in each group equidistantly distributed in a ring on the first mounting ring 9. The left and right groups of guiding and positioning units guide and position the straight sections of the upper end cap 001 and the lower end cap 003, respectively, and the equidistant ring arrangement positions the upper end cap 001 and the lower end cap 003 from all directions.

[0023] The guiding and positioning unit includes a second electric push rod 901 fixedly connected to the first mounting ring 9 and a positioning guide wheel 902 rotatably connected to the telescopic end of the second electric push rod 901 through a connecting frame. The outer ring surface of the positioning guide wheel 902 is configured as an arc shape that matches the outer ring surface of the end cap. This arc shape increases the contact area between the positioning guide wheel 902 and the outer ring surface of the end cap, preventing the outer ring surface of the end cap from being deformed by pressure.

[0024] The fixing unit includes a third electric push rod 903 fixedly connected to the first mounting ring 9 and an electric suction cup 904 fixedly connected to the telescopic end of the third electric push rod 903.

[0025] The barrel positioning assembly includes a second electric rotating ring 10 fixedly connected to the base frame 1, a fixed cylinder 11 fixedly connected to the rotating part of the second electric rotating ring 10, and two second mounting rings 12 fixedly connected to the fixed cylinder 11 via a connecting frame. Each of the second mounting rings 12 is equidistantly connected with several other guide positioning units and several other fixing units in a ring.

[0026] The padding assembly includes a second electric straightener 13, a mounting tube 15, and a padding support unit. The second electric straightener 13 is connected to the base frame 1, and an electric rotating frame 14 is connected to it. The second electric straightener 13 is configured as an electric slide rail and an electric slider, and the electric rotating frame 14 is moved by controlling the electric slider to slide on the electric slide rail. The mounting tube 15 is fixedly connected to the rotating part of the electric rotating frame 14, and a mounting rod 16 is inserted into the mounting tube 15. Several fourth electric push rods 1501 are provided on the mounting tube 15, and the initial extension ends of all the fourth electric push rods 1501 are inserted into the mounting rod 16. Several third electric straighteners 17 are connected to the mounting rod 16. Two padding support units are provided, each connected to the mounting rod 16 and several third electric straighteners 17. The mounting rod 16 is provided with an air supply channel 1602 that communicates with the mounting pipe 15, and the air supply channel 1602 is provided with a plurality of exhaust holes 1603 corresponding to the two pad support units. An arc-shaped sealing strip 1601 is provided on both sides of each of the exhaust holes 1603 on the outer ring surface of the mounting rod 16. The arc-shaped sealing strip 1601 is provided to ensure the sealing between the mounting rod 16 and the gasket support unit. The mounting rod 16 is provided with a plurality of limiting strips 1604, and the mounting tube 15 is provided with a sliding groove that matches the plurality of limiting strips 1604. The limiting strips 1604 cooperate with the sliding groove to limit and guide the mounting rod 16, so as to avoid the mounting rod 16 from being misaligned during assembly, which would prevent the fourth electric push rod 1501 from being unable to properly limit the mounting rod 16. The two pad support units are symmetrical from left to right. The third electric straightener 17 is configured as an electric slide rail and two electric sliders. The pad support units are driven to run by controlling the electric sliders to slide on the electric slide rail.

[0027] The padding support unit includes a first mounting plate 18 slidably connected to the mounting rod 16, a plurality of annularly distributed first connecting plates 19 movably connected to the first mounting plate 18 via a plurality of rotating shafts, a plurality of second connecting plates 21 movably connected to the plurality of first connecting plates 19 via rotating shafts, and a second mounting plate 22 movably connected to all the second connecting plates 21 via a plurality of rotating shafts. The first mounting plate 18 is configured as a hollow structure, and each of the first connecting plates 19 is provided with a vent groove 1901. The first mounting plate 18 is connected to a number of connecting hoses 20, and each of the connecting hoses 20 is connected to a vent groove 1901 of a first connecting plate 19. The vent groove 1901 and the first mounting plate 18 are connected through the connecting hoses 20, which facilitates the movement of the first connecting plate 19. Each of the first connecting plates 19 is connected to an installation module at its end. All the installation modules are bonded with a high-temperature resistant flexible adhesive ring 24. An annular ceramic gasket 25 is bonded to the outer ring surface of the high-temperature resistant flexible adhesive ring 24. The annular ceramic gasket 25 has a shaped groove on its outer ring surface.

[0028] The installation module includes a connector 23, which is detachably connected to the first connecting plate 19. The connector 23 is provided with a communication groove 2301 that communicates with the ventilation groove 1901. The high-temperature resistant flexible adhesive ring 24 and each of the connecting seats 23 are provided with a plurality of through grooves 2401 and a plurality of first air guide grooves 2402 that are connected to the through groove 2301. Each first air guide groove 2402 is connected to a first exhaust groove 2403. Cooling plates are provided on the part of the through groove 2401 that is directly opposite to the through groove 2301. The inner ring surface of the annular ceramic gasket 25 is provided with an annular second air guide groove 2501 that is connected to a plurality of through grooves 2401. The second air guide groove 2501 is connected to a plurality of second exhaust grooves 2502 and a plurality of third exhaust grooves 2503.

[0029] The inner ring surface of the high-temperature resistant flexible adhesive ring 24, which is bonded to the connecting seat 23, has a color that is different from the other parts. The outer ring surface of the high-temperature resistant flexible adhesive ring 24, which is bonded to the annular ceramic gasket 25, also has a color that is different from the other parts.

[0030] It also includes an automated positioning welding process adapted for electrolyte tanks, comprising the following steps: Step 1: Positioning. The barrel 002, lower end cap 003 and upper end cap 001 are placed sequentially by an external robotic arm or manually. The lower end cap 003 and upper end cap 001 are automatically positioned by two end cap positioning components. The barrel 002 is automatically positioned by the barrel positioning component. After positioning, the weld seam inside the barrel 002 is supported by the padding component. Step 2: Welding. The barrel 002, lower end 003 and upper end 001 are welded together by the welding assembly, the gasket assembly, the barrel positioning assembly and the two end cap positioning assemblies. Step 3: Exit. After welding is completed, control the gasket assembly to exit the barrel 002. Finally, use the external material handling equipment to remove the welded electrolyte barrel.

[0031] Before operation, the installation pipe 15 is connected to an external argon gas delivery device via a rotating conduit. The third electric actuator 17 controls the two first installation plates 18 to move closer to each other at a predetermined distance, causing the two padding support units to close like an umbrella to a predetermined degree. Specifically, several first connecting plates 19 and several second connecting plates 21 close like the frame of an umbrella, causing the two annular ceramic pads 25 to deform to a predetermined degree, thus reducing their outer diameter to facilitate the placement of the barrel 002 and the lower end cap 003. During operation, the barrel 002 is first placed by an external robotic arm, positioning it within the barrel positioning assembly at a predetermined position. The barrel 002 is then fitted over the two annular ceramic pads 25 of the padding assembly. The second electric push rod 901 extends the barrel to a predetermined length. The length guides the positioning guide wheel 902 to guide the barrel 002. The barrel 002 is positioned by several equally spaced annular positioning guide wheels 902. Then, the fixing units on the two second mounting rings 12 are controlled to operate, and the third electric push rod 903 is controlled to extend, causing the electric suction cup 904 to contact the surface of the barrel 002. Simultaneously, the electric suction cup 904 is activated to adhere and fix itself to the surface of the barrel 002. Next, the lower end cap 003 is placed and guided for positioning using the same steps, and then fixed by the fixing unit on the left first mounting ring 9. Then, the visual sensor 7 identifies the gap width at the weld between the barrel 002 and the lower end cap 003, and the first electric straightener 802 drives the left first mounting ring 9 and the lower end cap 003... The end cap 003 is moved and adjusted so that the gap width at the weld between the barrel body 002 and the lower end cap 003 meets the preset value. Then, the two first mounting plates 18 are reset by the third electric straight actuator 17, so that the two annular ceramic gaskets 25 are aligned with the inner wall of the barrel body 002 and the two weld seams. At this time, due to the support of the two gasket support units and the inner wall of the barrel body 002, the mounting rod 16 can remain stable after separating from the mounting tube 15. Then, the fourth electric push rod 1501 is retracted to release the limit on the mounting rod 16. Then, the electric rotating frame 14 is driven by the second electric straight actuator 13 to move the mounting tube 15 to the right by a preset distance. Then, the upper end cap 001 is placed into the first mounting ring 9 on the right, so that the mounting tube 15... The tube passes through the opening on the upper end cap 001 that is directly opposite the axis. Then, the second electric straight traveler 13 is controlled to drive the electric rotating frame 14 and the installation tube 15 to reset. The fourth electric push rod 1501 extends to lock the installation rod 16. The same operation is performed as described above to guide, position and adjust the lower end cap 003. The upper end cap 001 is guided, positioned and adjusted without manual adjustment. The barrel body 002, the upper end cap 001 and the lower end cap 003 are automatically positioned. Then, the position of the end of the welding torch 6 from the weld is identified by the vision sensor 7. The height of the welding torch 6 is adjusted by the electric lifter 3. The distance is adjusted by the extension and retraction of the first electric push rod 4 and the extension and retraction of the electric telescopic frame 5 so that the end of the welding torch 6 is at the preset position from the weld.

[0032] Next, the installation pipe 15 is started by connecting an external argon gas delivery device via a rotating conduit, allowing argon gas to pass sequentially through the installation pipe 15, installation rod 16, gas delivery channel 1602, exhaust port 1603, first installation plate 18, connecting hose 20, ventilation groove 1901, and connecting groove 2301. Then, it enters the through groove 2401 and the first gas guide groove 2402 through the connecting groove 2301, and the second gas guide groove 2501 through the through groove 2401. Finally, the argon gas passes through the second exhaust groove 2502 and the third exhaust groove. Gas outlets 2503 and the first exhaust outlet 2403 spray out gas to protect the weld seam, i.e., the weld edge area. The two welding torches 6, equipped with argon gas injection mechanisms, protect the other side of the weld area, preventing weld metal oxidation and alloy burn-off, which would reduce the mechanical properties and corrosion resistance of the weld metal. The two welding torches 6 are activated simultaneously to weld the upper head 001, barrel body 002, and lower head 003. Simultaneously, the two first electric rotating rings 8, the second electric rotating ring 10, and the electric rotating frame 14 are activated, causing the two heads... The positioning components, barrel positioning components, and gasket components rotate synchronously, causing the upper end cap 001, barrel 002, lower end cap 003, and two annular ceramic gaskets 25 to rotate synchronously. Then, two welding torches 6 simultaneously perform annular single-sided welding and double-sided forming on the upper end cap 001, barrel 002, and lower end cap 003. During welding, the forming grooves of the annular ceramic gaskets 25 limit the molten metal, allowing it to flow into the grooves and solidify to form a regular and full weld bead. This avoids the problems of irregular weld beads forming on the back side of the weld pool or depressions due to gravity caused by direct single-sided welding, ensuring the quality of single-sided welding and double-sided forming, and significantly reducing the post-weld repair rate. After welding, the cooling plates of the connecting groove 2301 and the through groove 2401 are activated, using cooled argon gas to cool the stainless steel at the edge of the welding area, increasing the heat dissipation rate inside the weld pool, and thus increasing the supercooling during the solidification process. This achieves grain refinement and improves the toughness and fatigue resistance of the weld.

[0033] After welding, the annular ceramic gasket 25 becomes brittle due to high temperature and cannot be reused. At this point, the right-side gasket support unit is controlled to retract, that is, the first mounting plate 18 and the second mounting plate 22 are moved away from each other by the third electric straight-line device 17, so that the right-side gasket support unit retracts like an umbrella to the end of its stroke. This causes the high-temperature resistant flexible adhesive ring 24 to retract and deform, thereby causing the brittle annular ceramic gasket 25 to break as the high-temperature resistant flexible adhesive ring 24 retracts. Most of the broken fragments of the annular ceramic gasket 25 are then fixed by the adhesive properties of the high-temperature resistant flexible adhesive ring 24. Then, the other gasket support unit is controlled to perform the same operation. Then, the second electric straight-line device is controlled to retract... The moving straight device 13 moves to the right. The size of the retracted pad support unit is smaller than the opening size of the upper end cap 001. The mounting rod 16 and the two pad support units are driven through the opening of the upper end cap 001 to carry out the retracted deformed high-temperature resistant flexible adhesive ring 24 and the broken annular ceramic pad 25. The fragments remaining in the electrolyte tank can be poured out through the opening of the upper end cap 001. Then the electrolyte tank can be removed. Before the next welding, new high-temperature resistant flexible adhesive rings 24 and annular ceramic pads 25 are installed on the two pad support units. The high-temperature resistant flexible adhesive rings 24 and annular ceramic pads 25 are used as consumable peripheral kits.
