[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0025] Example 1

[0026] Figure 1-Figure 5 As shown: A novel carbon-based substrate protective coating application system includes a spraying station room, a conveying and accumulating chain 3 installed in the spraying station room, and a circulating air system 8 arranged outside the spraying station room;

[0027] The spraying station room includes a primer spraying room 4, a flash drying room 5 and a topcoat spraying room 6 which are arranged in sequence along the traveling direction of the conveying and accumulating chain 3. A spraying robot 10 is provided in the primer spraying room 4 and the topcoat spraying room 6. A paint supply structure 12 connected to the spraying robot 10 is provided outside the primer spraying room 4 and the topcoat spraying room 6.

[0028] The circulating air system 8 includes a fan, an air inlet arranged at the top of the primer spraying room 4 and the topcoat spraying room 6, and an exhaust outlet arranged on the inner wall of the primer spraying room 4 and the topcoat spraying room 6. A paint mist replenishing structure 11 is provided at the exhaust outlet. The air inlet end of the fan is connected with the exhaust outlet through a pipe, and the air outlet end of the fan is connected with the air inlet. A paint mist replenishing structure 11 is installed at the exhaust outlet. The exhaust outlet in the primer spraying room 4 is also connected with the flash drying room 5 through a pipe. Part of the exhaust air is sent to the flash drying room 5 to reduce the energy consumption of the fan and maximize the utilization of the equipment. After the exhaust air is filtered, part of the air volume is used to supply air to the flash drying room, which is beneficial to the curing of the surface coating and reduces the damage to the primer coating during the topcoat spraying process. The circulating air is effectively utilized to save energy.

[0029] The paint mist replenishment structure 11 includes a dry-type capture paper box and a differential pressure gauge installed in the dry-type capture paper box. The differential pressure gauge transmits the pressure differential information of the paper box filtration system to the circulating air system. The air volume of the supply and exhaust air is adjusted according to the pressure difference of the paper box to ensure the stability of the continuous balance of the indoor cross-sectional wind speed.

[0030] A dust removal chamber 2 is provided on the side of the primer spraying chamber 4 away from the flash drying chamber 5. A dust collector is installed in the dust removal chamber 2. The dust collector is an adjustable compressed air nozzle. The adjustable compressed air nozzle is connected to the high-pressure air source. According to the workpiece profiling arrangement, when the workpiece arrives at the workstation, the surface of the workpiece is blown away, and the blown dust is collected by the dust removal equipment to ensure the cleanliness of the workpiece surface.

[0031] The dust removal chamber 2 is connected to the dust removal equipment 1, and the dust removal equipment 1 is connected to the negative pressure device. A filter element is installed in the dust removal equipment 1, and the negative pressure is used to collect the blown dust. The dust is removed by the filter element and then discharged after meeting the national emission standards.

[0032] A laser positioning structure 13, electrically connected to the spray robot 10, is also installed between the primer spray booth 4 and the dust removal chamber 2. During the production process, the anode carbon blocks are at varying heights above the ground and tend to tilt. The application system, located between the primer spray booth 4 and the dust removal chamber 2, measures the anode carbon blocks' height from the ground and their left and right eccentricity. This data is then transmitted to the spray robot 10 via a PLC. Based on the feedback from the laser positioning, the spray robot 10 uses an algorithm to calculate and adjust its trajectory, thereby ensuring the optimal spraying quality for each carbon block.

[0033] The entire set of equipment in the spray booth room adopts the structure of stainless steel + tempered glass, which is rust-proof and beautiful. A lighting lamp 7 is set outside the spray booth room to ensure that the illumination inside the spray booth room is not less than 800LUX. A closed door 9 is set at the entrance and exit of the spray booth room to prevent the exhaust from absorbing air from the door opening and destroying the wind balance of the segmented air supply.

[0034] The workpiece is transported to the dust removal chamber 2 under the conveying and accumulation chain 3. The dust removal chamber 2 uses compressed air to blow the surface of the workpiece to ensure the cleanliness of the workpiece surface. The dust blown off is collected by the dust removal equipment 1, and is discharged after the dust is removed by the filter element to meet the national emission standards. After dust removal, the workpiece is transported to the primer spraying room 4 by the conveying system, and a laser positioning structure 13 is set between the primer spraying room 4 and the dust removal chamber 2. The laser positioning structure 13 measures the height and inclination angle of the workpiece from the ground. And the relevant parameter system is transmitted to the spraying robot 10. The trajectory of the spraying robot 10 is offset calculated according to the measurement value of the laser positioning structure 13 and the spraying trajectory is adjusted according to the state of the workpiece to complete the automatic spraying work. The primer spraying room 4 uses natural wind, which enters the primer spraying room 4 after primary filtration. The exhaust air passes through the dry carton paint mist filtration system and is exhausted by the fan. Part of the exhaust air is used as the supply air for the flash drying chamber 5. The flash drying chamber 5 is located between the bottom primer spraying chamber 4 and the topcoat spraying chamber 6. The air outlet of the flash drying chamber 5 adopts a high-efficiency wind speed design mode, which can dry the surface of the workpiece at a high speed, ensuring the quick drying of the bottom spray and effectively preventing the damage to the bottom coating when the topcoat is sprayed. The circulating air system greatly reduces the equipment investment and effectively reduces energy. After the primer is flash-dried, it is transported to the topcoat spraying chamber 6 by the conveying and accumulating chain 3. Robotic automatic spraying is adopted. The spraying robot 10 in the topcoat spraying chamber 6 is a topcoat spraying robot. The spraying program of the primer spraying robot is reused to ensure the consistency of the primer and topcoat spraying. After the workpiece is sprayed, it is transported to the unloading position by the conveying and accumulating chain 3. After unloading, it is transported to the electrolytic cell for operation. The utility model not only ensures the automated operation process in the spraying operation section, but also reduces the supply and exhaust air volume of the equipment, achieving the purpose of green environmental protection and energy saving.

[0035] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
