Description

Technical Field

[0001] The present invention relates to the technical field of copper foil equipment manufacturing, and particularly relates to a device and a process for reducing welding and processing deformation at the ends of large-sized cathode rollers. Background Art

[0002] For a long time, there has been a large gap in the service stability between domestic cathode rollers and original Japanese cathode rollers. Especially for large-sized cathode rollers (φ3300), the service environment is harsh, being a copper sulfate solution at 60°C. When the roller body expands due to heat, due to the difference in the expansion coefficients of copper and titanium materials, it is easy to drive the deformation of the roller surface. In particular, the stress concentration at the ends of the cathode roller is obvious, the shrinkage deformation of the sealing plate and end ring welding is large, and there is also processing deformation. The superposition of welding and processing deformation leads to frequent problems of edge collapse at the ends, that is, the ends shrink and the straightness exceeds the tolerance. To solve the problem of edge collapse at the ends of the cathode roller, it is necessary to reduce the gap between the sealing plate, end ring and titanium cylinder. However, during the welding process of the cathode roller, the processing stress cannot be eliminated. Therefore, a device for reducing welding and processing deformation at the ends of large-sized cathode rollers is needed. Summary of the Invention

The bearing plate is driven to flip by the motor. A support ring is arranged at the end of the bearing plate away from the support seat. A welding detection mechanism is arranged on the support ring. There are two groups of the welding detection mechanisms and they are symmetrically arranged. A sliding groove is formed on the top surface of the support ring. The sliding groove is an annular groove. A sliding plate is slidably and matingly arranged in the sliding groove. The sliding plate is fixedly connected to the bottom of the end of the bearing plate. An electric wheel is arranged at the end of the bearing plate. The electric wheel is in contact with the top surface of the support ring. The electric wheel is a rubber wheel. A clamp is arranged on the base, and the clamp is used to clamp the cathode roller. When clamping the cathode roller, the central axis of the cathode roller is vertically arranged. In the initial state, the support ring is located above the cathode roller.

[0007] As a further improvement of the present technical solution, the welding detection mechanism includes a second pushing mechanism, a mounting plate, and a detection mechanism. The second pushing mechanism is arranged on the annular surface of the support ring. The mounting plate is arranged at the end of the second pushing mechanism. The detection mechanism is arranged on the mounting plate. On the plate surface of the mounting plate, a first support rod, a second support rod, and a third support rod are horizontally and fixedly arranged.

The second detection mechanism is arranged at the bottom of the third support rod and close to the end of the third support rod. The structures of the first detection mechanism and the second detection mechanism are the same.

[0008] As a further improvement of the present technical solution, the first detection mechanism includes a detection block, a connecting column, a connecting sleeve, a first support plate, and a guiding column. The detection block is at the bottom of the second support rod. The side wall of the detection block is flush with the end of the second support rod. The connecting column is vertically arranged on the top of the detection block. There are two connecting columns. The connecting sleeve is vertically arranged at the bottom of the second support rod. The connecting column is sleeved in the connecting sleeve. A spring is sleeved on the connecting column and the connecting sleeve. One end of the spring is connected to the bottom of the second support rod, and the other end of the spring is connected to the top of the detection block. The first support plate is arranged on the top of the detection block. A vertical column is vertically arranged at the bottom of the second support rod. A connecting shaft is arranged on the plate surface of the vertical column. A swing rod is arranged on the vertical column. The swing rod is rotatably connected to the vertical column through the connecting shaft. One end of the swing rod is close to the first support plate, and the other end of the swing rod is suspended. A guiding groove is formed on the plate surface of the swing rod. The guiding column is arranged on the plate surface of the first support plate. The guiding column is matched and sleeved in the guiding groove. A distance sensor is arranged on the second support rod. The distance sensor passes through the second support rod and extends to the bottom of the second support rod. The distance sensor is directly above the suspended end of the swing rod.

[0009] As a further improvement of the present technical solution, an exhaust pipe is arranged below the first support rod. The intake end of the exhaust pipe is close to the first detection mechanism, and the exhaust end of the exhaust pipe is close to the second detection mechanism. The intake port and the exhaust port of the exhaust pipe face the weld of the cathode roller. A fan is arranged on the exhaust pipe.

[0010] As a further improvement of the present technical solution, a second support plate is horizontally and fixedly arranged at the side wall of the first support rod. A lifting rod is arranged below the first support rod. The lifting rod is perpendicular to the first support rod. A guiding rod is vertically arranged at the top of the lifting rod. There are two guiding rods. The top of the guiding rod passes through the plate surface of the second support plate and is provided with a retaining piece.

[0011] As a further improvement of the present technical solution, a cylinder is arranged at the end of the lifting rod. The driving end of the cylinder is coaxially and fixedly connected with a limiting rod. A limiting plate is vertically arranged on the top of the detection block. The end of the limiting rod is close to the limiting plate. A plurality of limiting holes are formed on the plate surface of the limiting plate and are evenly arranged at intervals along the height direction of the limiting plate.

[0012] As a further improvement of this technical solution, a connecting housing is connected to the exhaust pipe. An impeller is rotatably arranged in the connecting housing. The top of the impeller passes through the connecting housing and is coaxially and fixedly connected to a turntable. A convex block is arranged on the top surface of the turntable. There are multiple convex blocks and they are evenly arranged around the edge of the turntable. The convex block is in the shape of a cone with the tip facing upward. A connecting plate is horizontally and fixedly connected to the wall of the lifting rod. The suspended end of the connecting plate is above the turntable and contacts the top surface of the turntable.

[0013] As a further improvement of this technical solution, a filter box is connected to the exhaust pipe.

[0014] Compared with the prior art, the progress and advantages of the present invention are as follows: During the use of the present invention, after the cathode roller is clamped, the pushing mechanism I and the lifting mechanism drive the support ring to be at the center directly above the cathode roller. The distance sensor detects the change process of the distance of the suspended end of the swing rod. At this time, the lifting mechanism stops working, and the electric wheel rotates to drive the support ring to rotate along the sliding plate, so that the welding torch welds the end of the cathode roller. When welding the weld of the cathode roller by setting two groups of detection and welding mechanisms, the welding efficiency of the weld of the cathode roller can be improved, and the welding deformation can be reduced;

[0015] When welding the weld of the cathode roller, the support ring rotates along the sliding plate. The temperature of the weld bead formed after the welding torch welds the weld is relatively high. The fan works to suck the hot air around the weld bead and discharge the hot air through the exhaust port of the exhaust pipe to the un-welded weld, so as to preheat the un-welded weld, which is beneficial to heat utilization;

[0016] After the weld of the cathode roller is welded, the detection block is moved along the weld bead of the cathode roller. The detection block moves up and down reciprocally to hammer the weld bead and reduce the welding deformation. Brief Description of the Drawings

[0036] As Figures 1-10 shown, a device for reducing the welding and machining deformation at the ends of a large-sized cathode roller includes:

[0037] Base 10, first pushing mechanism 110, lifting mechanism 120, support base 130, bearing plate 140. The first pushing mechanism 110 (which is prior art and will not be elaborated much) is arranged on the base 10. The pushing direction of the first pushing mechanism 110 is horizontally arranged. The lifting mechanism 120 (which is prior art and will not be elaborated much) is vertically arranged at the pushing end of the first pushing mechanism 110. The support base 130 is arranged on the top of the lifting mechanism 120. A bearing plate 140 is arranged at the side wall of the support base 130. A motor 141 is arranged at the side wall of the support base 130. The output shaft of the motor 141 is horizontally arranged. The bearing plate 140 is driven to flip by the motor 141. A support ring 160 is arranged at the end of the bearing plate 140 away from the support base 130. Two sets of detection and welding mechanisms 20 are arranged on the support ring 160 and are symmetrically arranged. A sliding groove 161 is formed on the top surface of the support ring 160. The sliding groove 161 is an annular groove. A sliding plate 142 is slidably and matingly arranged in the sliding groove 161. The sliding plate 142 is fixedly connected to the bottom of the end of the bearing plate 140. An electric wheel 143 is arranged at the end of the bearing plate 140. The electric wheel 143 is in contact with the top surface of the support ring 160. The electric wheel 143 is a rubber wheel. A clamp 150 (which is prior art and will not be elaborated much) is arranged on the base 10. The clamp 150 is used to clamp the cathode roller. When clamping the cathode roller, the central axis of the cathode roller is vertically arranged. In the initial state, the support ring 160 is above the cathode roller. When the electric wheel 143 rotates, it can drive the support ring 160 to rotate along the sliding plate 142, so that the detection and welding mechanism 20 detects and welds the end of the cathode roller.

[0038] More specifically, the detection and welding mechanism 20 includes a second pushing mechanism 210, a mounting plate 220, and a detection mechanism 30. The second pushing mechanism 210 (which is prior art and will not be elaborated much) is arranged on the annular surface of the support ring 160. The mounting plate 220 is arranged at the end of the second pushing mechanism 210. The detection mechanism 30 is arranged on the mounting plate 220. A first support rod 221, a second support rod 222, and a third support rod 223 are horizontally and fixedly arranged on the plate surface of the mounting plate 220. The first support rod 221 is between the first support rod 221 and the third support rod 223. A welding torch 224 is arranged at the end of the first support rod 221. The welding direction of the welding torch 224 is inclined downward. The detection mechanism 30 includes a first detection mechanism 310 and a second detection mechanism 320. The first detection mechanism 310 is arranged at the bottom of the second support rod 222 and close to the end of the second support rod 222. The second detection mechanism 320 is arranged at the bottom of the third support rod 223 and close to the end of the third support rod 223. The structures of the first detection mechanism 310 and the second detection mechanism 320 are the same.

[0039] As Figures 5-7As shown in the figure, the first detection mechanism 310 includes a detection block 311, a connecting column 312, a connecting sleeve 313, a first support plate 314, and a guiding column 315. The detection block 311 is located at the bottom of the second support rod 222, and the side wall of the detection block 311 is flush with the end of the second support rod 222. The connecting column 312 is vertically arranged on the top of the detection block 311, and there are two connecting columns 312. The connecting sleeve 313 is vertically arranged at the bottom of the second support rod 222, and the connecting column 312 is sleeved in the connecting sleeve 313. A spring is sleeved on the connecting column 312 and the connecting sleeve 313. One end of the spring is connected to the bottom of the second support rod 222, and the other end of the spring is connected to the top of the detection block 311. The first support plate 314 is arranged on the top of the detection block 311. A vertical column 226 is vertically arranged at the bottom of the second support rod 222. A connecting shaft 227 is arranged on the plate surface of the vertical column 226. A swing rod 228 is arranged on the vertical column 226. The swing rod 228 is rotatably connected to the vertical column 226 through the connecting shaft 227. One end of the swing rod 228 is close to the first support plate 314, and the other end of the swing rod 228 is suspended. A guiding groove 229 is formed on the plate surface of the swing rod 228. The guiding column 315 is arranged on the plate surface of the first support plate 314, and the guiding column 315 is correspondingly sleeved in the guiding groove 229. A distance sensor 225 is arranged on the second support rod 222. The distance sensor 225 passes through the second support rod 222 and extends into the bottom of the second support rod 222. The distance sensor 225 is directly above the suspended end of the swing rod 228. After the cathode roller is clamped, the first pushing mechanism 110 and the lifting mechanism 120 drive the support ring 160 to the center directly above the cathode roller. Then, the second pushing mechanism 210 drives the first support rod 221, the second support rod 222, and the third support rod 223 to move towards the inner wall of the titanium cylinder near the cathode roller, so that the ends of the first support rod 221, the second support rod 222, and the third support rod 223 contact the inner wall of the titanium cylinder. The welding torch 224 approaches the weld seam. Then, the lifting mechanism 120 drives the support ring 160 to move downward, so that the bottom of the detection block 311 abuts against the top surface of the cathode roller, so that the detection block 311 moves towards the second support rod 222. Then, the swing rod 228 is driven to deflect around the connecting shaft 227. The distance sensor 225 detects the distance change process of the suspended end of the swing rod 228. At this time, the lifting mechanism 120 stops working. The electric wheel 143 rotates to drive the support ring 160 to rotate along the sliding plate 142, so that the welding torch 224 welds the end of the cathode roller. When two sets of detection and welding mechanisms 20 are set to weld the cathode roller weld seam, the welding efficiency of the cathode roller weld seam can be improved, and the welding deformation can be reduced.

[0040] As Figure 5 , Figure 6 , Figure 9As shown, an exhaust pipe 330 is provided below the first support rod 221. The intake end of the exhaust pipe 330 is close to the first detection mechanism 310, and the exhaust end of the exhaust pipe 330 is close to the second detection mechanism 320. The intake port and the exhaust port of the exhaust pipe 330 face the weld of the cathode roller. A fan 331 is provided on the exhaust pipe 330. When welding the weld of the cathode roller, the support ring 160 rotates along the sliding plate 142. The temperature of the weld bead formed after the welding gun 224 welds the weld is relatively high. The fan 331 operates to suck the hot air around the weld bead and discharge the hot air through the exhaust port of the exhaust pipe 330 to the un-welded weld, thereby preheating the un-welded weld, which is beneficial to heat utilization.

[0041] As Figure 6 , Figures 8-10 shown, a second support plate 343 is horizontally and fixedly provided at the side wall of the first support rod 221. A lifting rod 340 is provided below the first support rod 221. The lifting rod 340 is perpendicular to the first support rod 221. A guide rod 344 is vertically provided at the top of the lifting rod 340. There are two guide rods 344. The top of the guide rod 344 passes through the plate surface of the second support plate 343 and is provided with a stop piece. A cylinder 341 is provided at the end of the lifting rod 340. The driving end of the cylinder 341 is coaxially and fixedly connected with a limiting rod 342. A limiting plate 316 is vertically provided at the top of the detection block 311. The end of the limiting rod 342 is close to the limiting plate 316. A limiting hole is formed on the plate surface of the limiting plate 316. There are multiple limiting holes and they are evenly spaced along the height direction of the limiting plate 316.

[0042] More specifically, a connecting housing 332 is connected to the exhaust pipe 330. An impeller 334 is rotatably arranged in the connecting housing 332. The top of the impeller 334 passes through the connecting housing 332 and is coaxially and fixedly connected to a turntable 335. A convex block 336 is arranged on the top surface of the turntable 335. There are multiple convex blocks 336 and they are evenly arranged around the edge of the turntable 335. The convex block 336 is in the shape of a cone with the tip facing upwards. A connecting plate 345 is horizontally and fixedly connected to the wall of the lifting rod 340. The suspended end of the connecting plate 345 is above the turntable 335 and contacts the top surface of the turntable 335. After the welding of the cathode roller weld is completed, the fan 331 stops working. The air cylinder 341 pushes the limiting rod 342 into the limiting hole of the limiting plate 316 to lock the detection block 311. Then the fan 331 works. The electric wheel 143 rotates to drive the support ring 160 to rotate along the sliding plate 142, so that the detection block 311 moves along the weld of the cathode roller. When the fan 331 works, the wind flowing through the connecting housing 332 blows the impeller 334 to rotate, driving the turntable 335 to rotate. The connecting plate 345 abuts against the conical surface of the convex block 336, driving the connecting plate 345 and the lifting rod 340 to reciprocate up and down along the guide rod 344, driving the detection block 311 to reciprocate up and down, and hammering the weld to reduce welding deformation.

[0043] More specifically, a filter box 333 is connected to the exhaust pipe 330 to facilitate filtering of impurities.

[0044] Working principle:

[0045] During the use of the present invention, after the cathode roller is clamped, the first pushing mechanism 110 and the lifting mechanism 120 drive the support ring 160 to the center directly above the cathode roller. Then, the second pushing mechanism 210 drives the first support rod 221, the second support rod 222, and the third support rod 223 to move towards the inner wall of the titanium cylinder close to the cathode roller, so that the ends of the first support rod 221, the second support rod 222, and the third support rod 223 contact the inner wall of the titanium cylinder. The welding torch 224 approaches the weld seam. Then, the lifting mechanism 120 drives the support ring 160 to move downward, so that the bottom of the detection block 311 abuts against the top surface of the cathode roller, causing the detection block 311 to move towards the second support rod 222. Then, the swing rod 228 is driven to deflect around the connecting shaft 227, and the distance sensor 225 detects the change process of the distance of the suspended end of the swing rod 228. At this time, the lifting mechanism 120 stops working, and the electric wheel 143 rotates to drive the support ring 160 to rotate along the sliding plate 142, so that the welding torch 224 welds the end of the cathode roller. When welding the weld seam of the cathode roller by setting two groups of detection and welding mechanisms 20, the welding efficiency of the weld seam of the cathode roller can be improved, and the welding deformation can be reduced. When welding the weld seam of the cathode roller, the support ring 160 rotates along the sliding plate 142, and the temperature of the weld bead formed after the welding torch 224 welds the weld seam is relatively high. The blower 331 works to suck the hot air around the weld bead and discharge the hot air through the exhaust port of the exhaust pipe 330 to the un-welded weld seam, so as to preheat the un-welded weld seam, which is beneficial to heat utilization. After the weld seam of the cathode roller is welded, the blower 331 stops working, and the cylinder 341 pushes the limiting rod 342 into the limiting hole of the limiting plate 316 to lock the detection block 311. Then, the blower 331 works, and the electric wheel 143 rotates to drive the support ring 160 to rotate along the sliding plate 142, so that the detection block 311 moves along the weld bead of the cathode roller. When the blower 331 works, the wind flowing through the communicating housing 332 blows the impeller 334 to rotate, driving the turntable 335 to rotate. The connecting plate 345 abuts against the conical surface of the convex block 336, driving the connecting plate 345 and the lifting rod 340 to reciprocate up and down along the guide rod 344, driving the detection block 311 to reciprocate up and down, and hammering the weld bead to reduce the welding deformation.

9. The processing technology of a device for reducing the welding and processing deformation at the end of a large-sized cathode roller according to claim 7, characterized in that: S1. After the cathode roller is clamped, the first pushing mechanism and the lifting mechanism drive the support ring to be at the center directly above the cathode roller. Then, the second pushing mechanism drives the first support rod, the second support rod, and the third support rod to move towards the inner wall of the titanium cylinder of the cathode roller, so that the ends of the first support rod, the second support rod, and the third support rod contact the inner wall of the titanium cylinder. The welding torch approaches the weld seam. Then, the lifting mechanism drives the support ring to move downwards, so that the bottom of the detection block abuts against the top surface of the cathode roller, so that the detection block moves towards the direction close to the second support rod. Then, the swing rod is driven to deflect around the connecting shaft. The distance sensor detects the change process of the distance of the suspended end of the swing rod. At this time, the lifting mechanism stops working. The electric wheel rotates to drive the support ring to rotate along the sliding plate, so that the welding torch welds the end of the cathode roller. S2. When welding the weld seam of the cathode roller, the support ring rotates along the sliding plate. The weld bead formed after the welding torch welds the weld seam has a relatively high temperature. The fan works to suck the hot air around the weld bead and discharge the hot air through the exhaust port of the exhaust pipe to the un-welded weld seam, so as to preheat the un-welded weld seam. S3. After the welding of the weld seam of the cathode roller is completed, the fan stops working. The cylinder pushes the limiting rod to insert into the limiting hole of the limiting plate to lock the detection block. Then, the fan works. The electric wheel rotates to drive the support ring to rotate along the sliding plate, so that the detection block moves along the weld bead of the cathode roller. When the fan works, the wind flowing through the communicating shell blows the impeller to rotate, so as to drive the turntable to rotate. The connecting plate abuts against the conical surface of the bump, so as to drive the connecting plate and the lifting rod to reciprocate up and down along the guide rod, so as to drive the detection block to reciprocate up and down, so as to hammer the weld bead and reduce the welding deformation.
