Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a robot spraying system for an anode carbon rod for aluminum. Background Art

[0002] In the production process of anode carbon rods for aluminum, in order to improve the performance and service life of anode carbon rods, it is usually necessary to spray the surface. Anode carbon rods are mainly used in the production of electrolytic aluminum, and the quality of their surface coating is directly related to their conductivity, corrosion resistance and wear resistance in the electrolytic cell. Traditional spraying operations usually use manual spraying, which has a series of technical and operational challenges, not only resulting in low production efficiency, but also unable to guarantee the consistency of coating quality.

[0003] In existing manual spraying operations, operators need to hold the spray gun for a long time to work, which is labor-intensive and long-term exposure to the spraying environment will also lead to health risks. The organic solvents in the paint will release harmful gases, and long-term inhalation may cause occupational diseases such as respiratory diseases and skin allergies. In addition, the spraying operation environment is harsh, and operators also have to face high temperatures, dust and potential explosion hazards, which poses great safety hazards. Therefore, existing manual spraying operations have serious efficiency problems, health hazards and safety risks.

[0004] At the same time, due to the lack of stability in manual operation, the skill level, working status and techniques of different operators will lead to inconsistent spraying quality, and defects such as uneven coating thickness, sagging and peeling are prone to occur. In addition, the waste of paint is serious and the material utilization rate is low, which further increases the production cost. Therefore, how to improve the accuracy and consistency of the anode carbon rod spraying process through automation technology has become an important demand in the industry. Summary of the invention

The carbon rod conveying system 1 includes a guide track 11, a drive mechanism 12, a suspension chain 13 and a suspension hanger 14. The guide track 11 is installed on the top of the workshop, and the suspension chain 13 is controlled by the drive mechanism 12 to move along a predetermined path. The suspension chain 13 is connected to the suspension hanger 14, and the suspension hanger 14 is used to fix the anode carbon rod to be sprayed. The anode carbon rod gradually enters the spray room mechanism 3 along the guide track 11.

[0060] When the anode carbon rod arrives at the spray room mechanism 3, the explosion-proof photoelectric sensor installed at the entrance of the spray room detects the arrival of the anode carbon rod and sends a signal to the control system. Subsequently, the automatic door mechanism 33 at the entrance of the spray room opens to allow the anode carbon rod to enter the spray room. After the anode carbon rod enters the spray room, the automatic door mechanism 33 closes to ensure airtightness during the spraying process.

[0061] A stop mechanism 4 is provided inside the spray room, and the stop mechanism 4 is used to fix the anode carbon rod in an appropriate position when it reaches the predetermined spraying position. The main components of the stop mechanism 4 include a stop block 41, a push rod and a stop block driving cylinder 46. The stop block 41 moves from the initial position to the stop position under the action of the stop block driving cylinder 46, preventing the anode carbon rod from moving forward and ensuring that it remains stable during the spraying process. Before the spraying operation begins, the stop block 41 is withdrawn to the initial position under the command of the control system to release the anode carbon rod.

[0062] During the spraying process, the six-axis spraying robot 21 set in the spraying room performs the spraying operation. The six-axis spraying robot 21 has highly flexible movement ability and can drive the spray gun 22 to spray the anode carbon rod comprehensively according to the preset path and parameters. The spray gun 22 is connected to the paint supply system 5 through the flow valve 23. The paint supply system 5 includes a large-capacity paint storage tank, a high-precision paint supply pump, a pressure sensor and a flow controller. The paint supply system 5 stably supplies paint to the spray gun 22 according to the spraying requirements to ensure that the flow and pressure of the paint are always maintained in an ideal state during the spraying process.

[0063] In order to ensure that the working environment in the spray room meets environmental protection and safety requirements, a filter cotton 32 is set at the bottom of the spray room to filter the excess paint and dust generated during the spraying process. In addition, the spray room is also equipped with a ventilation system 34, which includes a centrifugal fan, ventilation ducts, exhaust gas treatment devices and air volume control valves, which can timely discharge harmful gases and dust generated during the spraying process. The exhaust gas treatment device uses a combination of technologies such as activated carbon adsorption, catalytic combustion and plasma purification to ensure that the discharged gas meets national environmental protection standards.

[0064] After the spraying operation is completed, the automatic door mechanism 33 of the spraying room is opened again, and the driving mechanism 12 of the carbon rod conveying system 1 is started to continue to transport the anode carbon rods that have been sprayed to the next process. During the entire operation process, the control system communicates with the robot execution unit 2, the carbon rod conveying system 1, the paint supply system 5 and the various components of the spraying room to achieve automatic control of the entire spraying process. The control system can monitor the spraying parameters in real time and adjust the status of each device to ensure the stability and consistency of the spraying quality.

[0065] The robot spraying system of the present invention can not only significantly improve the spraying efficiency of the anode carbon rod, but also ensure the uniformity and quality of the coating and reduce the errors in manual operation. At the same time, the system effectively improves the working environment and reduces the health hazards to the operators through the automated exhaust gas treatment and filtration system, which meets the requirements of modern industrial production for high efficiency, safety and environmental protection.

[0066] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
