Description

[0001] This invention relates to the field of spraying equipment technology, and in particular to an automatic spraying robot system for prebaked anode carbon block anti-oxidation functional ceramic coating. Background Technology

[0002] Prebaked anode carbon blocks are the core anode material in electrolytic aluminum production. Their surface needs to be coated with an anti-oxidation functional ceramic coating to isolate air and electrolyte, extend service life, and ensure electrolysis efficiency.

[0003] Traditional automated spraying equipment for prebaked anode carbon blocks with anti-oxidation ceramic coatings primarily handles dust removal, spraying, and drying of the carbon blocks. However, its dust removal relies solely on a simple air jet method, lacking a brush cleaning structure, and can only remove surface dust. It cannot effectively remove stubborn dust from blind spots such as the bottom surface, sides, corners, and areas in contact with the feeding components, resulting in incomplete cleaning, unstable cleaning effects, and residual dust that can cause poor adhesion and insufficient bonding of subsequent coatings to the carbon blocks, affecting the coating's protective performance and shortening the anode carbon block's lifespan. This ultimately fails to meet the high standards of spraying quality required for industrial production. Summary of the Invention

[0024] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0025] Reference Figure 1-6 This invention discloses an automatic spraying robot system for prebaked anode carbon block anti-oxidation functional ceramic coating, comprising: considering the problems of secondary dust accumulation and easy damage to the coating caused by the dispersed process of traditional equipment during carbon block transportation, a dust removal chamber 8, a bottom spray chamber 9, a flash drying chamber 10, a spraying chamber 11, and a drying chamber 13 are connected end to end and interconnected through a connecting port 4; the dust removal chamber 8 is provided with a feed inlet 7, the drying chamber 13 is provided with a discharge outlet 1, the dust removal chamber 8, the bottom spray chamber 9, the flash drying chamber 10, the spraying chamber 11, and the drying chamber 13 are all provided with a feeding assembly, the bottom spray chamber 9 is provided with a bottom spraying assembly, the flash drying chamber 10 is provided with a fast-drying nozzle 43, the spraying chamber 11 is provided with an industrial robot 3, the end of the industrial robot 3 is fixedly connected with a nozzle 43, and the drying chamber 13 is provided with multiple hot air blowers 2.

[0026] Through the integrated cavity design with the head and tail connected, and the feeding components that run through the entire process, the charcoal blocks are seamlessly transported from feeding to discharging, avoiding secondary pollution and coating damage during the transfer process, ensuring the continuous and efficient operation of each process, and improving production continuity.

[0027] Considering that traditional jet dust removal cannot clean the stubborn dust on the bottom and left and right sides of the carbon block, a dust removal nozzle 41 and a dust extraction nozzle 42 are embedded through the dust removal chamber 8 and are symmetrically arranged. An auxiliary cleaning component is provided in the dust removal chamber 8. The auxiliary cleaning component includes: multiple main slide rods 31 fixedly connected in the dust removal chamber 8, two brackets 29 slidably arranged outside the main slide rods 31, and a transverse slide rod 30 fixedly connected between the two brackets 29. A brush 28 is slidably sleeved on the outer wall of the transverse slide rod 30 for cleaning the bottom and left and right sides of the anode carbon block 27.

[0028] Dust removal chamber 8 is symmetrically equipped with dust removal nozzles 41 and suction nozzles 42. The brush 28 of the auxiliary cleaning component slides along the horizontal slide bar 30. With the help of airflow, it efficiently removes dust from the bottom surface and left and right sides of the carbon block, reduces cleaning blind spots, and provides a clean surface for spraying.

[0029] Considering the problem that dust is easily left on the front and back sides and corners of the carbon block and that cleaning is not thorough, the auxiliary cleaning components also include: two brushes 33, four electric slide rails 35 which are fixedly connected to the side surfaces of the two brackets 29 in two groups, and a support plate 34 which is slidably connected in the electric slide rails 35. Multiple longitudinal slide rods 32 are fixedly connected between each pair of support plates 34. The two brushes 33 are slidably connected to the outer wall of the corresponding longitudinal slide rods 32 for cleaning the front and back sides of the anode carbon block 27.

[0030] The electric slide rail 35 drives the support plate 34 to rise and fall, which in turn drives the brush 2 33 to slide along the longitudinal slide bar 32, specifically cleaning the front and back sides of the carbon block, accurately cleaning the residual dust on the front and back sides and corners, further expanding the cleaning coverage and improving the thoroughness of cleaning;

[0031] Considering the issue of power transmission for cleaning with the brush 28, the auxiliary cleaning components also include: a support rod 23 fixedly connected to the side surface of the bracket 29, and a side connecting block 20 fixedly connected to the side surface of the brush 28; a rotating shaft 18 is rotatably connected to the inner surface of the support rod 23, a cam 15 is fixedly connected to the upper end of the rotating shaft 18, a crank 17 is hinged to the protrusion of the cam 15, and the other end of the crank 17 is hinged to the side connecting block 20.

[0032] When the bracket 29 moves, the gear 19 meshes with the rack 16 to drive the rotating shaft 18 to rotate. The cam 15 drives the brush 28 to move back and forth through the crank 17, so that the brush 28 can repeatedly scrape at high frequency, greatly improving the cleaning efficiency and effectively removing stubborn attachments.

[0033] Considering the issue of power transmission for cleaning by the second brush 33, the auxiliary cleaning components also include: a connecting frame 40 fixedly connected between the two second brushes 33, a side plate 12 fixedly connected to the side surface of the bracket 29, and a support rod 21 fixedly connected to the front surface of the side plate 12; a rotating shaft 36 is rotatably connected inside the support rod 21, a cam 37 is fixedly connected to the lower end of the rotating shaft 36, a connecting slide rod 38 is fixedly connected to the lower surface of the cam 37, and a crank 39 is hinged to the lower surface of the connecting frame 40, with the other end of the crank 39 sleeved on the outer wall of the connecting slide rod 38;

[0034] Gear 22 meshes with rack 16 to drive shaft 2 36 to rotate. Cam 2 37 drives brush 2 33 to reciprocate through connecting slide rod 38 and crank 2 39, so that the action of brush 2 33 is synchronized with the carbon block conveying, improving the uniformity of cleaning and avoiding local dust residue.

[0035] Considering the problem that the brush drive requires additional power and has high energy consumption, the auxiliary cleaning components also include: a rack 16 fixedly connected to the inner surface of the dust removal chamber 8, a gear 19 fixedly connected to the outer wall of the rotating shaft 18, a gear 22 fixedly connected to the outer wall of the rotating shaft 2 36, and both gear 22 and gear 19 meshing with the rack 16.

[0036] The carbon block conveyor drives the support 29 to move. Through the meshing of gear 19 and gear 22 with the fixed rack 16, the rotating shaft 18 and rotating shaft 26 can rotate automatically without the need for an additional power source, reducing equipment energy consumption and achieving adaptive matching between cleaning frequency and conveying speed.

[0037] In summary, the improvement of this embodiment lies in:

[0038] The auxiliary cleaning components of this equipment adopt a "mechanical linkage + multi-brush collaboration" design, which breaks through the blind spots of traditional dust removal and achieves all-dimensional cleaning of the carbon blocks without dead angles. Brush 1 28 and brush 2 33 can specifically clean the bottom and sides, effectively removing stubborn residues and greatly improving cleaning efficiency. No additional power is required, it is adaptable to different conveying speeds, and the cleaning effect is stable. It avoids the problem of insufficient coating adhesion caused by dust and lays a solid cleaning foundation for subsequent spraying.

[0039] Based on the above, other structures also need to be disclosed in detail, such as:

[0040] The feeding assembly includes: an electric slide rail 14 that is fixedly connected to the dust removal chamber 8, the bottom spray chamber 9, the flash drying chamber 10, the spraying chamber 11, and the drying chamber 13. A bearing slider 24 is slidably connected to the inner surface of the electric slide rail 14. A steel claw 25 is fixedly connected to the lower surface of the bearing slider 24. An anode carbon block 27 is movably connected to the lower surface of the steel claw 25. A baffle 26 is sleeved on the outside of the steel claw 25 and is movably connected above the anode carbon block 27.

[0041] The bottom spraying assembly includes: electric slide rail 2 5 and bottom nozzle 6. The electric slide rail 2 5 is fixedly connected to the inner surface of the bottom spray chamber 9, and the bottom nozzle 6 is slidably connected inside the electric slide rail 2 5 with the nozzle facing upward.

[0042] Specifically: Electric slide rail 14, electric slide rail 2 5, and electric slide rail 3 35 are all displacement transmission components composed of a motor and a lead screw. This is a mature existing technology and is well known to people in this field, so it will not be elaborated on in this article.

[0043] Specifically: Industrial robot 3 is an automated or semi-automated mechanical device that can move in multiple dimensions through program control or manual operation, and is used to drive nozzle 43 to precisely spray coating around anode carbon block 27 to form a preset coating. This is an existing mature technology and is well known to people in this field, so it will not be described in detail in this article.

[0044] Working principle: In use, the anode carbon block 27 is fixedly connected to the steel claw 25. The input end of the dust removal nozzle 41 and the quick-drying nozzle 43 is connected to the external air pump equipment, and the output end of the dust suction head 42 is connected to the external negative pressure air extraction equipment. Then, the anode carbon block 27 enters the dust removal chamber 8 through the feed port 7. The electric slide rail 14 of the feeding component drives the bearing slider 24 to drive the steel claw 25 to transport smoothly. The baffle 26 outside the steel claw 25 covers the carbon bowl of the anode carbon block 27 for protection.

[0045] After the anode carbon block 27 moves into the dust removal chamber 8, the electric slide rail 35 drives the support plate 34 to rise, causing the two brushes 2 33 to rise to the front and rear sides of the anode carbon block 27. The dust removal nozzle 41 and the dust extraction nozzle 42 symmetrically spray air to extract dust, and the auxiliary cleaning components work synchronously: the anode carbon block 27 pushes the brushes 2 33 forward, causing the bracket 29 to move along the main slide bar 31 with the carbon block conveyor. The gears 1 19, 2 22 and rack 16 mesh to drive the rotating shafts 1 18 and 2 36 to rotate. The cam 1 15 drives the brush 1 28 to move back and forth along the transverse slide bar 30 through the crank 1 17. In conjunction with the cam 2 37, the connecting slide bar 38 and the crank 2 39, the brush 2 33 moves back and forth along the longitudinal slide bar 32 to remove the carbon block dust from all directions.

[0046] After cleaning, the carbon block enters the bottom spray chamber 9 through the connecting port 4. The electric slide rail 2 5 drives the bottom nozzle 6 to spray the bottom surface upward. Then it enters the flash drying chamber 10, where the quick-drying nozzle 43 quickly dries the base coat. Next, it enters the spraying chamber 11, where the industrial robot 3 completes the side and top surface spraying. Finally, it enters the drying chamber 13, where multiple hot air blowers 2 cure the coating. The finished product is output through the discharge port 1.

[0047] The entire process of cleaning, spraying, and drying is automated through an integrated cavity and linkage structure, eliminating the need for additional power to drive the cleaning components and ensuring efficient and continuous operation.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
