Description

Technical Field

[0001] This invention relates to the field of coating spraying equipment, specifically to an automatic coating instrument for aluminum electrolytic anodes. Background Technology

[0002] To reduce the ineffective oxidation consumption of aluminum electrolysis anode blocks, the industry will spray a layer of high-temperature resistant and anti-oxidation coating on the surface of the aluminum electrolysis anode blocks. The main purpose is to isolate the aluminum electrolysis anode blocks from contact with oxygen in the air during the aluminum electrolysis process, thereby preventing ineffective raw material consumption.

[0003] When spraying dual anodes, the assembled anode blocks need to be placed on a channel steel support frame that is 600mm high, 1700mm wide, and 1700mm long using a forklift. Operators need to use a handheld pneumatic sprayer for spraying. During the handheld spraying process, the operator needs to manually rotate around the finished anode to spray, resulting in low spraying efficiency. In addition, the spray paint bucket needs to be manually changed and stirred after every eight sets of anodes are sprayed, resulting in high labor intensity and waste of manpower. Summary of the Invention

[0010] Preferably, the telescopic expansion mechanism includes a bidirectional ball screw slide installed below the mounting base plate. Both sides of the movable end of the bidirectional ball screw slide are provided with expansion mounting plates. A connecting rod is installed between the expansion mounting plate and the movable end of the bidirectional ball screw slide.

[0011] Preferably, the external automatic spraying device includes a horizontal ball screw slide mounted on an expansion mounting plate, a linkage adjustment frame mounted on the horizontal ball screw slide, a long spray pipe mounted on the linkage adjustment frame, the long spray pipe being covered with spray nozzles, and a spraying limit mechanism mounted at the bottom of the linkage adjustment frame.

[0012] Preferably, the linkage adjustment frame includes a horizontal mounting plate installed on the movable end of the horizontal ball screw slide, an adjusting nut installed on the horizontal mounting plate, a lifting mounting rod installed below the horizontal mounting plate, a threaded rod at the top of the lifting mounting rod, the threaded rod being threadedly connected to the adjusting nut, a limiting mounting groove at the end of the lifting mounting rod away from the threaded rod, and a linkage adjustment rod installed between the lifting mounting rod and the horizontal mounting plate.

[0015] The advantages of this invention compared to the prior art are: The lifting and hoisting device synchronously lowers the outer automatic spraying device, the inner automatic spraying device, the telescopic expansion mechanism, and the rotation adjustment device, causing the bottom of the telescopic expansion mechanism to contact the top of the aluminum electrolytic double anode block. The telescopic expansion mechanism then synchronously retracts, causing the outer automatic spraying device to contact the outer wall of the aluminum electrolytic double anode block. The outer automatic spraying device sprays the aluminum electrolytic double anode block, while the inner automatic spraying device sprays the inner middle section of the block. After spraying, the inner automatic spraying device automatically resets. After spraying one side of the aluminum electrolytic double anode block, the telescopic expansion mechanism and rotation adjustment device can rotate the outer automatic spraying device to switch positions, allowing for full-area spraying of the aluminum electrolytic double anode block surface. This effectively saves manpower and improves work efficiency. Attached Figure Description

Detailed Implementation

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 11As shown, an automatic spraying device for aluminum electrolysis anodes includes an automatic spraying apparatus for spraying aluminum electrolysis anodes. The automatic spraying apparatus includes a lifting and hoisting device 1 mounted on a mobile device. A rotation adjustment device 2 is installed on the lifting end of the lifting and hoisting device 1. An inner automatic spraying device 3 is installed on the rotation adjustment device 2. A telescopic expansion mechanism 4 is also installed at the bottom of the inner automatic spraying device 3. An outer automatic spraying device 5 is installed on the expansion end of the telescopic expansion mechanism 4. A recognition camera is also installed at the bottom of the telescopic expansion mechanism 4. A limiting placement device 6 is installed below the recognition camera. A limiting placement groove is provided inside the limiting placement device 6.

[0030] The preferred mobile device is a gantry frame, which can drive the lifting and hoisting device 1 to adjust the position of the equipment. When the surface of the aluminum electrolytic double anode block needs to be coated with anti-oxidation paint, the worker uses a forklift to place the aluminum electrolytic double anode block into the limiting placement slot of the limiting placement device 6. The limiting placement slot can effectively guide the aluminum electrolytic double anode block to be placed directly below the recognition camera. After the recognition camera recognizes that the aluminum electrolytic double anode block is in place, the lifting and hoisting device 1 will drive the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4, and the rotation adjustment device 2 to descend synchronously, so that the bottom of the telescopic expansion mechanism 4 is aligned with the top of the aluminum electrolytic double anode block. When the telescopic expansion mechanism 4 retracts and moves synchronously, it causes the outer automatic spraying device 5 to come into contact with the outer wall of the aluminum electrolytic double anode block. The outer automatic spraying device 5 sprays the aluminum electrolytic double anode block, while the inner automatic spraying device 3 sprays the inner middle part of the aluminum electrolytic double anode block. After the inner automatic spraying device 3 finishes spraying, it will automatically reset. After the outer automatic spraying device 5 finishes spraying one side of the aluminum electrolytic double anode block, the outer automatic spraying device 5 can be rotated and switched positions by the cooperation of the telescopic expansion mechanism 4 and the rotation adjustment device 2 to spray the entire surface of the aluminum electrolytic double anode block.

[0031] See Figure 2 and Figure 3 As shown, the lifting and hoisting device 1 includes a fixed mounting frame 11 installed on the mobile device. A hoisting mounting plate 12 is installed below the fixed mounting frame 11. Several first limiting guide posts 13 are installed on the hoisting mounting plate 12. One end of the first limiting guide post 13 away from the hoisting mounting plate 12 extends through the fixed mounting frame 11. A winding machine 14 is also installed on the fixed mounting frame 11. The hoisting rope on the winding machine 14 is connected to the hoisting mounting plate 12.

[0032] After the camera identifies the aluminum electrolysis double anode block as placed, the hoisting rope is loosened by the winding machine 14. The loosening of the hoisting rope will cause the hoisting installation plate 12 to descend. The first limit guide column 13 can effectively limit and guide to ensure the stability of the lifting position. When the hoisting installation plate 12 is lifted, it will drive the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4 and the rotation adjustment device 2 to descend synchronously, effectively driving the equipment to lift and adjust its position.

[0033] See Figures 2 to 4 As shown, the rotation adjustment device 2 includes a rotating mounting column 21 mounted on the hoisting mounting plate 12. The rotation adjustment device 2 also includes a rotation drive device 22 for driving the rotating mounting column 21 to rotate. The rotation drive device 22 also includes a rotating gear ring 221 mounted on the rotating mounting column 21. A first rotation driver 222 is mounted on the side of the rotating gear ring 221. A drive gear 223 is mounted on the output end of the first rotation driver 222. The drive gear 223 meshes with the rotating gear ring 221.

[0034] The first rotary driver 222 is preferably a servo motor. When it is necessary to rotate to adjust the position of the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4, and the rotary adjustment device 2, the servo motor drives the drive gear 223 to rotate. When the drive gear 223 rotates, it drives the rotating gear ring 221 to rotate synchronously. When the rotating gear ring 221 rotates, it drives the rotating mounting column 21 to rotate synchronously. The rotation of the rotating mounting column 21 can drive the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4, and the rotary adjustment device 2 to rotate synchronously to adjust their positions. The rotation adjustment angle can be effectively controlled by the servo motor.

[0035] See Figure 4 and Figure 5 As shown, the inner automatic spraying device 3 includes a mounting base plate 31 installed at the bottom of a rotating mounting column 21. Rotating brackets 38 are installed at both ends of the mounting base plate 31. A first mounting plate 32 and a second mounting plate 33 are installed on the rotating mounting column 21. A lifting mounting plate 35 is installed between the first mounting plate 32 and the second mounting plate 33. Adjusting screws 34 are also installed on the first mounting plate 32 and the second mounting plate 33. A second rotary driver 36 is also installed on the second mounting plate 33. The output end of the second rotary driver 36 is connected to the adjusting screw 34. The adjusting screw 34 is threadedly connected to the lifting mounting plate 35. Synchronous retraction rods 37 are installed at both ends of the lifting mounting plate 35. The end of the synchronous retraction rod 37 away from the lifting mounting plate 35 is connected to the rotating bracket 38. Extended spraying devices 39 are evenly installed on the rotating bracket 38.

[0036] The second rotary drive 36 is preferably a servo motor. When the outer automatic spraying device 5 sprays the aluminum electrolytic double anode block, and it is necessary to spray the anti-oxidation coating on the inner middle part of the aluminum electrolytic double anode block, the servo motor drives the adjusting screw 34 to rotate. When the adjusting screw 34 rotates, it drives the lifting mounting plate 35 to move downward. When the lifting mounting plate 35 moves downward, it drives the synchronous contraction rod 37 to move outward. When the synchronous contraction rod 37 moves outward, it can effectively drive the rotating bracket 38 to rotate. When the rotating bracket 38 rotates, it drives the extension spraying device 39 to remain horizontal. When the extension spraying device 39 is in a horizontal state, the extension spraying device 39 can move towards the inner middle part of the aluminum electrolytic double anode block. When the extension spraying device 39 moves, it simultaneously sprays the anti-oxidation coating onto the middle part of the aluminum electrolytic double anode block.

[0037] See Figure 5 and Figure 6 As shown, the extended spraying device 39 includes a limiting mounting seat 391 mounted on the rotating bracket 38, a telescopic rack 392 mounted on the limiting mounting seat 391, a third rotary driver 393 mounted on the limiting mounting seat 391, a drive gear 394 mounted on the output end of the third rotary driver 393, the drive gear 394 meshing with the telescopic rack 392, and a V-shaped spraying pipe 395 mounted on the telescopic end of the telescopic rack 392, the V-shaped spraying pipe 395 being covered with spray nozzles.

[0038] The third rotary actuator 393 is preferably a servo motor. When the rotating bracket 38 rotates, it will drive the limiting mounting seat 391 to rotate to a horizontal state. The servo motor drives the drive gear 394 to rotate. When the drive gear 394 rotates, it will drive the telescopic rack 392 to move along the limiting mounting seat 391. When the telescopic rack 392 moves along the telescopic rack, it will drive the V-shaped spray pipe 395 to move to the inner middle position of the aluminum electrolysis double anode block. When the V-shaped spray pipe 395 moves, it will spray the anti-oxidation coating onto the inner middle position of the double anode block through the spray nozzle.

[0039] See Figure 2 and Figure 7 As shown, the telescopic expansion mechanism 4 includes a bidirectional ball screw slide 41 installed below the mounting base plate 31. Both sides of the movable end of the bidirectional ball screw slide 41 are provided with expansion mounting plates 43. A connecting rod 42 is installed between the expansion mounting plate 43 and the movable end of the bidirectional ball screw slide 41. A second limiting guide post 44 is also installed on the expansion mounting plate 43. The end of the second limiting guide post 44 away from the expansion mounting plate 43 is slidably connected to the bidirectional ball screw slide 41.

[0040] When it is necessary to synchronously expand and adjust the position of the automatic spraying devices 5 on both sides, the connecting rods 42 on both sides are driven to move synchronously by the bidirectional ball screw slide 41. When the connecting rods 42 move, they will push the expansion mounting plate 43 to move telescopically. The second limit guide post 44 can ensure the stability of the telescopic movement of the expansion mounting plate 43. When the expansion mounting plate 43 moves, it will drive the automatic spraying devices 5 on both sides to adjust their positions synchronously.

[0041] See Figure 7 and Figure 8 As shown, the outer automatic spraying device 5 includes a horizontal ball screw slide 51 mounted on the expansion mounting plate 43. A linkage adjustment frame 53 is mounted on the horizontal ball screw slide 51. A long spray pipe 52 is mounted on the linkage adjustment frame 53. The long spray pipe 52 is covered with spray nozzles. A spraying limit mechanism 54 is also mounted at the bottom of the linkage adjustment frame 53.

[0042] When the expansion mounting plate 43 of the telescopic expansion mechanism 4 moves, it will drive the horizontal ball screw slide 51 to move synchronously, so that the linkage adjustment frame 53 and the long spray pipe 52 are adjusted to the appropriate spraying position. At the same time, the spraying limiting mechanism 54 abuts against the outer wall of the aluminum electrolytic double anode block. The horizontal ball screw slide 51 will drive the linkage adjustment frame 53 to move horizontally. When the linkage adjustment frame 53 moves along the horizontal ball screw slide 51, the long spray pipe will spray the anti-oxidation coating onto the outer wall of the aluminum electrolytic double anode block through the spray nozzle. The spraying limiting mechanism 54 can effectively block the spraying position.

[0043] See Figure 8 and Figure 9 As shown, the linkage adjustment frame 53 includes a horizontal mounting plate 531 installed on the movable end of the horizontal ball screw slide 51. An adjusting nut 532 is installed on the horizontal mounting plate 531. A lifting mounting rod 534 is installed below the horizontal mounting plate 531. A threaded rod 535 is provided at the top of the lifting mounting rod 534. The threaded rod 535 is threadedly connected to the adjusting nut 532. A limiting mounting groove 536 is provided at the end of the lifting mounting rod 534 away from the threaded rod 535. A linkage adjustment rod 533 is also installed between the lifting mounting rod 534 and the horizontal mounting plate 531.

[0044] When the operator rotates the adjusting nut 532, the position of the threaded rod 535 can be effectively adjusted. When the threaded rod 535 is adjusted, it will drive the lifting mounting rod 534 and the linkage adjusting rod 533 to move up and down synchronously. When the lifting mounting rod 534 and the linkage adjusting rod 533 move up and down synchronously, the height of the long spraying pipe 52 and the spraying limit mechanism 54 can be effectively adjusted, thus effectively controlling the spraying height.

[0045] See Figure 9 and Figure 10As shown, the spraying limiting mechanism 54 is installed inside the limiting mounting groove 536 on the rotating mounting plate 541. The abutting end of the rotating mounting plate 541 is provided with several abutting balls 542. The rotating mounting plate 541 is also covered with masking stickers. The spraying limiting mechanism 54 also includes a rotating mounting sleeve 543 installed on the lifting mounting rod 534. A guide connecting post 544 is installed inside the rotating mounting sleeve 543. One end of the guide connecting post 544 is connected to the rotating mounting plate 541. A return spring 545 is also installed between the rotating mounting sleeve 543 and the rotating mounting plate 541.

[0046] The limiting mounting groove 536 of the lifting mounting rod 534 is used to limit the installation of the rotating mounting plate 541. When the lifting mounting rod 534 retracts, it will drive the abutting ball 542 on the side of the rotating mounting plate 541 to abut against the side of the aluminum electrolytic double anode block. When the rotating mounting plate 541 abuts against the side of the aluminum electrolytic double anode block, it will push the guide connecting column 544 to retract and move towards the rotating mounting sleeve 543. The return spring 545 will be squeezed. The squeezing force of the return spring 545 can effectively press the rotating mounting plate 541, so that the side of the rotating mounting plate 541 abuts against the side of the aluminum electrolytic double anode block. When the long strip spraying pipe 52 sprays the aluminum electrolytic double anode block, the rotating mounting plate 541 can effectively limit and block the spraying range, effectively control the spraying range and improve the spraying quality. When the staff needs to clean the surface of the rotating mounting plate 541, the staff can directly peel off the masking sticker on the surface to quickly clean the surface of the rotating mounting plate 541.

[0047] See Figure 11 As shown, the automatic spraying device also includes a rotary stirring device for automatically mixing the spraying liquid. The rotary stirring device includes multiple mixing tanks 71 for mixing the coating. Each mixing tank 71 is equipped with a solenoid valve 72 at its outlet end. A delivery pump 73 is provided on the side of the mixing tank 71. The input end of the delivery pump 73 is connected to the solenoid valve 72. The output end of the delivery pump 73 is connected to both the inner automatic spraying device 3 and the outer automatic spraying device 5.

[0048] Multiple mixing tanks 71 are used to mix and stir the paint. During each spraying, the solenoid valve 72 controls the delivery pump 73 to draw paint from the mixing tank 71. The delivery pump 73 delivers the paint to the spraying ends of the inner automatic spraying device 3 and the outer automatic spraying device 5. A weight detector is also installed at the bottom of the mixing tank 71. The weight detector can effectively detect the amount of paint stored in the mixing tank 71. If one mixing tank 71 is short of paint, the solenoid valve 72 will close, and the solenoid valve 72 of the other mixing tank 71 will open, which facilitates continuous delivery of paint and improves work efficiency. At the same time, the operator can add raw materials to the empty mixing tank 71 for mixing.

[0049] Specific working principle: Workers use a forklift to place the aluminum electrolytic double anode block into the limiting placement slot of the limiting placement device 6. The limiting placement slot effectively guides the aluminum electrolytic double anode block to be placed directly below the recognition camera. After the recognition camera recognizes that the aluminum electrolytic double anode block is in place, the lifting and hoisting device 1 will drive the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4, and the rotation adjustment device 2 to descend synchronously, so that the bottom of the telescopic expansion mechanism 4 contacts the top of the aluminum electrolytic double anode block. The telescopic expansion mechanism 4 then retracts synchronously. When the telescopic expansion mechanism 4 retracts, it will drive the outer automatic spraying device 5, the inner automatic spraying device 3, the telescopic expansion mechanism 4, and the rotation adjustment device 2 to descend synchronously. The spraying device 5 contacts the outer wall of the aluminum electrolytic double anode block. The outer automatic spraying device 5 sprays the aluminum electrolytic double anode block, while the inner automatic spraying device 3 sprays the inner middle part of the aluminum electrolytic double anode block. After the inner automatic spraying device 3 finishes spraying, it will automatically reset. After the outer automatic spraying device 5 finishes spraying one side of the aluminum electrolytic double anode block, the outer automatic spraying device 5 can be rotated and switched positions through the cooperation of the telescopic expansion mechanism 4 and the rotation adjustment device 2 to spray the entire surface of the aluminum electrolytic double anode block, effectively saving manpower and improving work efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
