Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a titanium cylinder welding device for a cathode roller. Background Art

[0002] The titanium cylinder is the core component of precision electrochemical processing equipment such as electrolytic copper foil and lithium battery copper foil. It is made of industrial pure titanium or titanium alloys such as TA1 and TA2. It has high strength, corrosion resistance (can resist erosion by electrolytes such as sulfuric acid and hydrochloric acid), high conductivity and high-temperature stability. Through precision surface polishing and conductive treatment, it can stably carry the cathode reduction reaction during high-speed rotation, ensuring that copper ions are evenly deposited to form ultra-thin copper foil with a thickness of microns, which directly affects the crystallization quality and surface finish of the copper foil.

[0003] However, in the actual manufacturing process, titanium cylinder welding has the characteristic of low thermal conductivity. The thermal conductivity coefficient of titanium is only 1 / 5 of that of steel. The welding heat is difficult to diffuse quickly, resulting in the instantaneous temperature of the weld area exceeding 1600℃, and the temperature difference with the adjacent area can reach more than 800℃. Combined with the low elastic modulus characteristic of titanium, the thermal stress can easily break through the yield strength of the material, causing plastic deformation of the titanium cylinder such as distortion and excessive ovality, affecting the qualified rate of the finished product of the titanium cylinder. Therefore, we propose a new type of titanium cylinder welding device for cathode rollers. Summary of the Invention

[0014] The present invention has the following beneficial effects:

[0015] 1.

[0016] 2. The present invention uses a motor to drive the shaft to rotate and drive the wedge block and the arc-shaped support block to move to support and fix the inner wall of the titanium cylinder. Compared with traditional rigid clamping, it avoids the risk of deformation of the titanium cylinder during welding due to local stress concentration. At the same time, this fixing method can be flexibly applied to the position fixation and support of titanium cylinders of different diameters, thereby improving the versatility and practicality of the equipment.

[0017] 3. This invention uses an inert gas generator to provide inert gas protection. The gas is delivered to the inner and outer surfaces of the titanium cylinder through gas injection and distribution pipes, creating an oxygen-free environment. This not only prevents damage to the weld due to high-temperature oxidation, but also removes localized heat accumulation through gas flow, promoting uniform temperature distribution and reducing transient high-temperature gradients caused by low thermal conductivity, thereby improving weld quality and further compensating for the large temperature differences found in traditional welding.

[0018] 4. After welding is completed, the present invention continuously supplies inert gas until the titanium cylinder cools naturally. This process gradually releases residual welding stress, avoids shrinkage deformation caused by sudden cooling, and ensures the geometric accuracy and surface finish of the titanium cylinder. Furthermore, by ensuring the geometric accuracy and surface finish of the titanium cylinder, the qualified rate and service life of the finished product are ultimately improved. This combination of precise control and automation gives the present invention broader application prospects and higher market competitiveness in the field of titanium cylinder welding.

[0036] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0037] The present invention provides a technical solution:

[0038] See also Figures 1 to 11A titanium cylinder welding device for a cathode roller is characterized in that it includes a base 1 and a welding platform 2 fixedly installed on the base 1, and an anti-deformation mechanism 3 is provided on the welding platform 2.

[0039] The anti-deformation mechanism 3 includes a motor 301 fixedly mounted at the bottom center of the welding table 2, a shaft 302 fixedly mounted on the output end of the motor 301, a plurality of gas boxes 303 are arranged on the outside of the shaft 302, the shaft 302 passes through the gas boxes 303, and the gas boxes 303 are distributed in a vertical stack, wherein the gas box 303 at the bottom of the stack is fixedly connected to the welding table 2, and the remaining gas boxes 303 are connected to each other in turn through a plurality of support ducts 3031, and a plurality of gas boxes 303 are provided with a plurality of support ducts 3031. Dry exhaust hole 3032; the outer side of the shaft 302 is fixedly installed with a shaft ring 304 located at the bottom of the inner cavity of the air box 303, and the outer cylindrical surface of the shaft ring 304 is fixedly installed with five wedge blocks 305, and the inclined surfaces of the five wedge blocks 305 are provided with telescopic inclined blocks 306 that are slidably connected to the air box 303. The wedge blocks 305 are adapted to the telescopic inclined blocks 306, and the end of the telescopic inclined block 306 away from the wedge block 305 is fixedly installed with an arc-shaped support block 307, and the tops of several air boxes 303 are fixedly installed with linkage structures 308.

[0040] The anti-deformation mechanism 3 uses a motor 301 to drive the shaft 302 to rotate, driving the wedge block 305 on the collar 302 to rotate synchronously. This pushes the telescopic bevel block 306 to slide along the gas box 303, allowing the arc-shaped support block 307 to fit the inner wall of the titanium cylinder to form multiple points of support. The linkage structure 308 ensures stable support. At the same time, the inert gas generator 309 provides inert gas protection, creating an oxygen-free environment and removing heat, promoting uniform temperature distribution. This effectively disperses welding thermal stress, reducing the risk of titanium cylinder deformation. The synergistic effect of mechanical support and gas protection solves the deformation problem during titanium cylinder welding, improving weld quality and the yield rate of finished products.

[0041] The anti-deformation mechanism 3 also includes an inert gas generator 309 fixedly installed at the top center of the base 1. An inert gas distribution cylinder 310 is fixedly installed at the output end of the inert gas generator 309. The top end of the inert gas distribution cylinder 310 is fixedly connected to the motor 301. Several distribution pipes 311 are fixedly installed on the inert gas distribution cylinder 310. A nozzle component 312 is fixedly installed at the gas outlet end of the distribution pipe 311. An injection angle adjustment structure 313 is provided at the middle section of the nozzle component 312.

[0042] The inert gas generator 309 in the anti-deformation mechanism 3 provides inert gas, which is delivered to the nozzle assembly 312 via the inert gas distribution cylinder 310 and distribution pipe 311. This forms a gas wall outside the weld to prevent high-temperature oxidation. Simultaneously, some inert gas is injected into the gas box 303, connected through the support conduit 3031, and evenly ejected from the exhaust hole 3032, forming a flowing gas column within the titanium cylinder, achieving dual oxygen-free protection inside and outside. This process not only improves welding quality but also removes heat through the gas flow, promoting uniform temperature distribution and reducing the transient high-temperature gradient caused by the low thermal conductivity of titanium.

[0043] See also Figure 2 、 Figure 5 and Figure 7 The linkage structure 308 includes a base ring 3081 fixedly installed on the top of the air box 303, five base rods 3082 fixedly installed on the outer circular surface of the base ring 3081, and a telescopic spring 3083 fixedly installed in the inner cavity of the base rod 3082. A linkage rod 3084 is fixedly installed on the end of the telescopic spring 3083 away from the base ring 3081, and the linkage rod 3084 is slidably connected to the base rod 3082.

[0044] The linkage structure 308 consists of a base ring 3081, a base rod 3082, a telescopic spring 3083, and a linkage rod 3084. The motor 301 drives the shaft 302 to rotate, driving the wedge block 305 to rotate, pushing the telescopic bevel block 306 to slide along the air box 303. At this time, the telescopic spring 3083 is deformed under force, and the linkage rod 3084 slides along the base rod 3082, ensuring that the arc-shaped support block 307 is stably and evenly attached to the inner wall of the titanium cylinder, achieving multi-point support and adapting to titanium cylinders of different diameters. The sliding of the linkage rod 3084 and the elastic force of the telescopic spring 3083 ensure the stable movement of the arc-shaped support block 307, preventing the arc-shaped support block 307 and the telescopic bevel block 306 from detaching from the air box 303.

[0045] In some embodiments, the vertical length of the arc-shaped support block 307 is equal to the vertical length of the support tube 3031 plus the air box 303 plus the base ring 3081, wherein the vertical length of the base ring 3081 is equal to the vertical length of the support tube 3031.

[0046] In this embodiment, the vertical length of the arc-shaped support block 307 is set to be equal to the vertical length of the support tube 3031 plus the air box 303 plus the base ring 3081, so that the arc-shaped support block 307 can be supported at the top and bottom during the movement (that is, several arc-shaped support blocks 307 support each other), making the movement of the arc-shaped support block 307 more stable; at the same time, the base ring 3081 is equal in length to the support tube 3031, making the structure compact and stable, and able to support the air box 303, so that the structure of several air boxes 303 is more stable and convenient for daily use.

[0047] See also Figures 1 to 3 and Figures 8 to 11 The distribution pipe 311 includes a plurality of inclined tubes 3111 fixedly mounted on the inert gas distribution cylinder 310 and communicating with the inner cavity of the inert gas distribution cylinder 310. The outlet ends of the plurality of inclined tubes 3111 are fixedly mounted with distribution rings 3112 communicating with the inner cavities of the inclined tubes 3111. The distribution rings 3112 are fixedly mounted with right-angle tubes 3113 communicating with the inner cavities of the distribution rings 3112. The outlet ends of the right-angle tubes 3113 are fixedly mounted with rigid connecting tubes 3111 communicating with the inner cavities of the right-angle tubes 3113. 4. The air outlet end of the rigid connecting tube 3114 is fixedly connected to the nozzle part 312; the nozzle part 312 is composed of a bamboo tube and an inert gas nozzle, wherein the bamboo tube is made of POM material; the distribution tube 311 also includes a gas injection tube 3115 fixedly installed on the top of the distribution ring 3112 and connected to the inner cavity of the distribution ring 3112, the gas injection tube 3115 passes through the welding table 2, and the air outlet end of the gas injection tube 3115 is fixedly connected to the gas box 303 at the bottom of the stack and the inner cavities are connected to each other.

[0048] The distribution pipe 311 is a key channel for delivering inert gas. After the gas generated by the inert gas generator 309 enters the inert gas distribution tube 310, it flows through the inclined tube 3111 to the distribution ring 3112. It is then transported to the nozzle assembly 312 via the right-angle tube 313 and the rigid connecting tube 3114, forming a gas wall outside the weld to prevent high-temperature oxidation. Simultaneously, some gas is injected into the gas box 303 through the gas injection pipe 3115. After connecting through the support conduit 3031, it is evenly ejected from the exhaust hole 3032, forming a flowing gas column within the titanium cylinder, achieving dual oxygen-free protection inside and outside. The distribution pipe 311's internal structure precisely controls the gas flow, ensuring uniform distribution of the inert gas and improving weld quality. It is a key component for ensuring a smooth welding process.

[0049] See also Figure 1 、 Figure 8 and Figure 9 The spray angle adjustment structure 313 includes a head cover 3131 fixedly mounted on the nozzle part 312 and adapted to the nozzle part 312. The head cover 3131 is fixedly mounted on the middle section of the bamboo tube on the nozzle part 312. The number of head covers 3131 is several, and the head covers 3131 and the nozzle part 312 are in a one-to-one correspondence. A spray angle adjustment ring 3132 is fixedly mounted on the head cover 3131, and an electric telescopic rod 3133 fixedly connected to the welding table 2 is symmetrically mounted on the bottom of the spray angle adjustment ring 3132. The output end of the electric telescopic rod 3133 is fixedly connected to the spray angle adjustment ring 3132.

[0050] The spray angle adjustment structure 313 consists of a head cover 3131, a spray angle adjustment ring 3132, and an electric telescopic rod 3133. The electric telescopic rod 3133 drives the spray angle adjustment ring 3132 to move vertically up and down through its telescopic action, thereby adjusting the spray angle of the nozzle component 312 (the head cover 3131 is installed in the middle section of the bamboo tube on the nozzle component 312. The vertical movement of the electric telescopic rod 3133 causes the bamboo tube to bend, thereby changing the spray angle). This allows the nozzle to be precisely aligned with the weld position, ensuring that the inert gas forms an effective gas wall outside the weld to prevent high-temperature oxidation. At the same time, the bamboo tube made of POM material combines flexibility and inert gas compatibility, making the spray angle adjustment flexible and precise. By controlling the direction of gas injection, this structure improves welding quality and achieves efficient oxygen-free protection during welding, providing stable and reliable technical support for titanium cylinder welding.

[0051] See also Figure 1 and Figure 2 Three robotic arms 4 are fixedly mounted on the outer circumferential surface of the base 1 , and welding heads 5 are fixedly mounted on the execution ends of the three robotic arms 4 .

[0052] Three robotic arms 4 are fixed to the outer circumference of the base 1, with welding heads 5 precisely mounted on the actuating end to ensure welding stability. Before welding, the robotic arms 4 are adjusted to a preset position, with the welding heads 5 aligned with the weld seam. During welding, the robotic arms 4 coordinate with the welding heads 5 to follow the set welding trajectory, improving efficiency and quality. Under the precise control of the robotic arms 4, the welding heads 5 achieve fast and stable welding, eliminating manual errors. This design enhances welding automation, precisely controls weld consistency and aesthetics, and significantly improves the yield rate and service life of finished products.

[0053] The working principle of the present invention is as follows:

[0054] When using the device to weld titanium cylinders, first place two titanium cylinders with the same diameter vertically on the welding table 2 in a stacked manner (see Figure 1) so that it passes through the shaft 302 and adjusts its position, manually ensuring that the welding interfaces of the two titanium cylinders are precisely aligned. In order to solve the problem of welding heat accumulation caused by the low thermal conductivity of titanium materials, the device realizes dynamic support and stress dispersion through the anti-deformation mechanism 3. Start the motor 301 to drive the shaft 302 to rotate in the forward direction, driving the wedge block 305 on the collar 304 to rotate synchronously. The inclined surface of the wedge block 305 interacts with the telescopic bevel block 306, pushing the telescopic bevel block 306 to slide outward along the inner wall of the air box 303. The linkage structure 308 can prevent the arc-shaped support block 307 and the telescopic bevel block 306 from detaching from the air box (it is also convenient for the telescopic spring 3083 to assist the linkage rod 3084, the arc-shaped support block 307, and the telescopic bevel block 306 to retract inward when the motor 301 rotates in the opposite direction). The linkage rod 3084 moves outward smoothly, and finally the arc-shaped support block 307 is evenly fitted to the inner wall of the titanium cylinder. This design replaces the traditional external clamps with multi-point internal supports, which not only avoids the local stress concentration caused by rigid clamping, but also uses the circumferential distribution of the arc-shaped support block 307 to offset the welding thermal stress, significantly reducing the risk of excessive ovality or distortion of the titanium cylinder due to the low elastic modulus.

[0055] After completing the positioning, adjust the spray angle of the nozzle part 312 according to the position of the weld. By controlling the extension and contraction of the electric telescopic rod 3133, the spray angle adjustment ring 3132 is driven to deflect, and the head cover 3131 is fixed to the middle section of the bamboo tube of the nozzle part 312. The material is made of POM, which has both flexibility and inert gas compatibility, so that the nozzle can be accurately aligned with the weld as the bamboo tube deforms. (In order to isolate the external airflow interference, a windbreak wall can be added around the device to form a closed welding environment to ensure the stability of the inert gas protection effect.) Then start the inert gas generator 309 (such as argon), and the inert gas is diverted to each inclined tube 3111 through the inert gas distribution cylinder 310, and is transported to the nozzle part 312 through the distribution ring 3112, the right-angle tube 3113 and the rigid connecting tube 3114, forming an inert gas wall on the outer surface of the weld to prevent high-temperature oxidation. At the same time, part of the inert gas is injected into the stacked gas boxes 303 through the gas injection pipe 3115, and the supporting conduit 3031 connects the gas boxes 303 of each layer, and finally is evenly ejected from the exhaust hole 3032, forming a continuously flowing inert gas column in the inner cavity of the titanium cylinder, completely replacing the internal air, and realizing dual oxygen-free protection inside and outside.

[0056] During the welding process, three robotic arms 4 drive the welding head 5 to weld along a preset trajectory. The circulation of inert gas inside and outside the titanium cylinder not only isolates oxygen, but also takes away local accumulated heat through the airflow, promotes uniform temperature distribution, and reduces the instantaneous high temperature gradient caused by low thermal conductivity. After welding is completed, the inert gas is continuously supplied until the titanium cylinder naturally cools to room temperature. This slow cooling process gradually releases the residual stress of welding, avoids shrinkage deformation caused by sudden cooling, and ensures the geometric accuracy and surface finish of the titanium cylinder. The entire device solves the core problem of titanium welding through the multi-dimensional coordination of mechanical support, gas protection, and dynamic temperature control, and significantly improves the qualified rate and service life of finished products.

[0057] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
