The traditional manual cleaning method has the following defects: low efficiency, high labor intensity, poor working environment, unstable quality, etc. Although the existing automated cleaning technologies have been improved, there are still the following problems: high tool wear: directly cleaning high-bonding areas leads to frequent tool replacement, and it is difficult to clean carbon blocks with severe sticking materials thoroughly; incomplete cleaning: the existing systems rely on conveyor roller tracks and cleaning mechanisms, but lack a turning mechanism, making it difficult to cover all sides of the carbon blocks; poor adaptability: the fixed parameter design cannot adapt to different sticking material distributions and carbon block sizes.

The first cylinder drives the first roller cutter to approach the small-end surfaces on both sides of the anode carbon block, and the materials on the small-end surfaces on both sides of the anode carbon block are cut off by the rotation of the first roller cutter. After being cut, the materials fall into the material collection device below. Step 3.3: When the first hydraulic cylinder pushes the anode carbon block through the small-end surface cleaning device, the first limit module sends a limit signal to the main control module. The main control module controls the first hydraulic cylinder to retract to the initial position and controls the small-end surface roller motor and the first cylinder of the small-end surface cleaning device to stop running and retract to the initial position respectively.

After the anode carbon block reaches the designated position, the second limit module sends a limit signal to the main control module, and the main control module starts the carbon bowl cleaning device. Step 4.2: The second cylinder pushes the carbon bowl cleaning rotary cutter close to the anode carbon block. The carbon bowl cleaning motor drives the carbon bowl cleaning rotary cutter to rotate. During the rotation, the carbon bowl cleaning rotary cutter advances into the carbon bowl. The carbon bowl cleaning rotary cutter scrapes off the filling material in the carbon bowl, and the wire brush on the cutter head of the carbon bowl cleaning rotary cutter clears the filling material out of the carbon bowl.

The third cylinder respectively pushes the special-shaped cutter, the third roller cutter, the second roller cutter, and the chamfering cutter to approach the top surface, bottom surface, two large-end surfaces, and bottom chamfer of the anode carbon block. The materials on the surface of the anode carbon block are cut off by the rotation of the special-shaped cutter, the third roller cutter, and the second roller cutter. Step 5.4: When the limit sensor at the exit of the large-end surface cleaning device senses the anode carbon block, it sends a limit signal to the main control module.

[0039] The robot cleaning device 10 includes a roller bed. A machine vision positioning system and a robot cleaning arm 10-1 are arranged on one side of the roller bed. A lifting device is arranged above the roller bed. There are several toothed roller wheels 10-3 arranged in parallel on the roller bed. The several toothed roller wheels 10-3 are drivingly connected to each other. The toothed roller wheels 10-3 are driven to rotate by a roller motor 10-2. It further includes a material collection device, and the material collection device is arranged at the bottoms of the small-end surface cleaning device 4, the carbon bowl cleaning platform 5, the drum turning device 8, the large-end surface cleaning device 9, the robot cleaning device 10, and the purging cleaning device.
[0040] In the embodiment of the present invention, the ungrouping receiving frame 1 is connected with a cross-rotating positioning device 3. The two ends of the cross-rotating positioning device 3 are respectively connected with a first hydraulic cylinder 2 and a small-end surface cleaning device 4. A carbon bowl cleaning platform 5 is connected behind the small-end surface cleaning device 4. A carbon bowl cleaning device 6 is installed on the carbon bowl cleaning platform 5 to clean the carbon bowl. A second hydraulic cylinder 7 and a drum turning device 8 are respectively connected in front of and behind the carbon bowl cleaning device 6. A large-end surface cleaning device 9 is connected behind the drum turning device 8. A robot cleaning device 10 is connected behind the large-end surface cleaning device 9. Four first roller cutters 4-1 are installed inside the small-end surface cleaning device 4. The first roller cutters 4-1 are driven to rotate by a motor and are pushed by a first air cylinder to closely adhere to the surface of the anode carbon block 11. Several rollers 4-2 are arranged at the bottom, and the rollers 4-2 are drivingly connected by a chain. The driving of the rollers is realized by a speed reducer and a small-end surface roller motor 4-3. Four circular carbon bowl cleaning rotary cutters 6-2 are installed on the carbon bowl cleaning device 6. The carbon bowl cleaning rotary cutters 6-2 are fixed at one end of a rotating shaft, and the other end is connected with a speed reducer and a carbon bowl cleaning motor 6-1. The cutters are driven to rotate by the carbon bowl cleaning motor 6-1. A total of six second roller cutters 9-1 are installed on the left and right sides inside the large-end surface cleaning device 9, and three "dumbbell"-shaped special-shaped cutters 14 are installed on the top. The special-shaped cutters 14 adopt a through-shaft special-shaped cutter, and the rotating shaft 13 effectively improves the strength and service life of the cutters. All the roller cutters are driven by a servo motor and are pushed by a third air cylinder to closely adhere to the surface of the anode carbon block 11. The bottom chamfer of the anode carbon block 11 is slightly sticky with materials, so two chamfer scrapers 15 are installed inside the large-end surface cleaning device 9 to clean the two bottom edges of the anode carbon block 11 respectively. The robot cleaning device 10 mainly includes a roller bed and a robot cleaning arm 10-1. The robot cleaning arm 10-1 is independent of the roller bed and is fixed on the concrete structure at the bottom. Several toothed rollers 10-3 are fixed on the roller bed through bearing seats. Each toothed roller is connected by a chain. Driving one roller by the roller motor 10-2 can drive several rollers on the entire roller bed to rotate, so as to realize the transmission of the carbon block.
[0041] In the embodiment of the present invention, after the anode carbon block 11 enters the small-end surface cleaning device 4, upon recognition of the entry of the carbon block by the small-end surface cleaning device 4, the first roller cutter 4-1 with a hardness not less than 60 HRC driven by a servo motor and rotating at high speed is pressed against the surface of the anode carbon block 11 under the action of a cylinder, and the filling material adhered to the surface of the anode carbon block 11 is cleaned off by the high-speed rotating first roller cutter 4-1; after the cleaning is completed, the cylinder retracts to about 50 mm away from the small end surface of the anode carbon block 11, and at the same time, the servo motor gradually reduces the rotational speed until it stops rotating; the first roller cutter 4-1 can automatically adjust the rotational speed (500-2000 rpm) and pressure (0.3-0.5 MPa) according to the thickness of the adhered material, and the cleaning time is about 30 seconds.
[0042] After the small end surface of the anode carbon block 11 is cleaned, the anode carbon block 11 enters the carbon bowl cleaning platform 5. At this time, the carbon bowls of the anode carbon block 11 all face the same side. After the anode carbon block 11 reaches the designated position, the carbon bowl cleaning device 6 pushes the carbon bowl cleaning rotary cutter 6-2 into the carbon bowl to achieve the preliminary cleaning of the carbon bowl; the carbon bowl cleaning rotary cutter 6-2 is made of tungsten carbide and has a hardness ≥90 HRC. The carbon bowl cleaning rotary cutter 6-2 is slightly smaller than the diameter of the carbon bowl, and the cleaning time is fixed at 10 seconds. During the cleaning process, under the action of the centrifugal force generated by the rotation of the carbon bowl cleaning rotary cutter 6-2, most of the materials fall from the carbon bowl into the material collection device below. The carbon bowl cleaning rotary cutter 6-2 is driven by the carbon bowl cleaning motor 6-1. After the cleaning is completed, the second hydraulic cylinder 7 drives the carbon bowl cleaning device 6 to withdraw along the slide rail.
[0043] After the drum flipping device 8 adjusts the position of the anode carbon block 11, it is pushed into the large-end surface cleaning device 9. There are three groups of roller cutters on the upper, lower, left, and right sides of the large-end surface cleaning device 9, with a rotational speed of 1000-1800 rpm and a pressure of 1.5-2.5 MPa; the large-end surface cleaning device 9 synchronously cleans the large end surface of the anode carbon block 11. After the anode carbon block 11 enters the large-end surface cleaning device 9, the large-end surface cleaning device 9 recognizes the entry signal of the anode carbon block 11. The roller cutter driven by a servo motor and rotating at high speed is pressed against the surface of the anode carbon block 11 under the action of a cylinder, and the filling material adhered to the surface of the carbon block is cleaned off by the high-speed rotating roller cutter. After the cleaning is completed, the cylinder retracts to about 50 mm away from the small end surface of the carbon block, and at the same time, the servo motor gradually reduces the rotational speed until it stops rotating. The roller cutter can automatically adjust the rotational speed and pressure according to the thickness of the adhered material, and the cleaning time is about 40 seconds. The top surface of the anode carbon block 11 is an irregular plane, and the top roller cutter in the large-end surface cleaning device 9 uses a special-shaped cutter 14, which is tightly pressed against the top surface of the anode carbon block 11 by a cylinder during the cleaning process; roller cutters are respectively arranged on the upper side, lower side, left side, and right side of the large-end surface cleaning device 9. Among them, the roller cutters on the upper and lower sides rotate in the opposite direction to those on the left and right sides, or the rotation direction of one roller cutter in the middle of each side is the same as the advancing direction of the oil cylinder, and the rest are opposite. The purpose of such a design is to offset part of the resistance and reduce the advancing load of the oil cylinder.
[0044] After the pre - cleaning stage of the anode carbon block 11 is completed, the anode carbon block 11 is transported to the robot cleaning device 10 by the toothed roller 10 - 1 for secondary cleaning. The robot cleaning device 10 generates high - precision point cloud data through visual recognition and path planning, and dynamically plans the cleaning path. Based on the feedback of the force sensor and the infrared sensor, the tool pressure (0.1 - 0.5 MPa) and the motion trajectory are adjusted in real time to ensure that all surfaces of the whole carbon block are cleaned. After the robot cleaning device 10 finishes cleaning, there is still a small amount of material remaining in the carbon bowl of the carbon block. When the anode carbon block 11 enters the purging and cleaning device, the purging head is aligned obliquely above the carbon bowl, and compressed air is controlled by a solenoid valve to blow the carbon bowl. The blown - out material falls into the material collection and recycling device, and the dust is taken away by the dust collector to ensure that there is no dust flying at the site.
[0045] In the pre - cleaning stage of the present invention, more than 90% of the adhering materials are removed, and the remaining are handed over to the intelligent robot for cleaning. The pre - cleaning is also divided into three stages: cleaning the two small end faces of the carbon block, cleaning the carbon bowl, and cleaning the remaining four faces, namely the bottom face, the top face of the carbon block, and the two large end faces. Changing the centralized cleaning to segmented cleaning greatly improves the cleaning efficiency; the irregular surface at the top is finely cleaned at the intelligent robot station to achieve efficient cleaning of the carbon block. The time taken for a single robot to clean the entire carbon block is about 3 - 4 minutes. By using the cleaning method of the present invention, the time consumption is shortened to about 1 minute, and the overall efficiency is increased by 60%; the unit price of the robot tool is high and the loss is fast. Coupled with other sensitive and high - precision spare parts of the robot, the cleaning method using only the robot is costly. By using the cleaning method of the present invention, the maintenance cost can be effectively reduced by about 60%, greatly alleviating the pressure on the production cost of the enterprise.
[0046] The present invention cleans all surfaces of the carbon block, including the bottom face that is difficult for the robot to clean. Through multi - station collaborative cleaning, it is ensured that the cleanliness of the four side faces, the bottom face, the top face of the carbon block, and the carbon bowl is ≥99%, greatly improving the cleaning quality of the pre - baked anode. In the present invention, the pre - cleaning station has less dust emission compared to robot cleaning. In addition, after pre - cleaning, the cleaning amount of the intelligent robot is low, and the dust emission is correspondingly less. Coupled with the closed - type negative - pressure dust removal design, the dust collection effect is good, meeting the GBZ2.12019 standard; the largest irregular surface of the pre - baked anode is at the top of the carbon block, and the other surfaces are basically regular surfaces. The adhering materials on the other surfaces and in the carbon bowl are pre - cleaned by the pre - cleaning equipment, and only a small part of the irregular top is handed over to the intelligent robot for cleaning. The robot can achieve cleaning of different shapes through the AI recognition system.
[0047] The present invention combines the pre - cleaning technology and the robot cleaning in a coordinated manner, improving the problems of the existing robot cleaning technology, which can partially replace manual labor but is limited by the large difference in the bonding strength of the carbon block surface and the complex working conditions, resulting in unstable cleaning effect, high tool loss, and high cost.
