[0018] The specific embodiments of the utility model are further explained in detail by comparing the drawings and describing the embodiments, and the purpose is to help the technical personnel in the field to have a more complete, accurate and deep understanding of the concept and technical scheme of the utility model, and to help its implementation.

[0019] As Figs. 1-3 shown, the utility model provides a kind of hot wheel laser marking device, including industrial robot 1, identification scanning mechanism for gathering wheel identification area image, primer spraying mechanism for being used to spray primer to wheel and laser marking head 4 for marking identification information on wheel, identification scanning mechanism, primer spraying mechanism and laser marking head 4 are arranged on industrial robot 1.

[0020] Specifically, as Figs. 1-3As shown, the industrial robot 1 is a six-axis robot. The hot wheel laser marking device is installed in the output roller area of the tempering furnace, the wheels output from the tempering furnace are conveyed through the output roller, the end effector of the industrial robot 1 is provided with a protective cover 2, a laser marking head 4 is fixedly installed in the protective cover 2, an opening aligned with the laser marking head 4 is arranged on the side wall of the protective cover 2, and the light beam generated by the laser marking head 4 can be ensured to be emitted outward to perform the marking work. The industrial robot 1 drives the protective cover 2 and the laser marking head 4 in the protective cover 2 to move, and the function of multi-angle free marking can be achieved. The laser generator is arranged on the base of the industrial robot 1, and the laser generator is connected with the laser marking head 4 (such as optical fiber connection). The laser generator is installed on the robot base, which greatly reduces the mechanical arm load, and correspondingly reduces the robot matching cost.

[0021] As preferred, the protective cover 2 is connected with a gas supply system, and the gas supply system introduces gas into the protective cover 2 to form a positive pressure in the protective cover 2. The laser marking head 4 is installed in the protective cover 2, which can protect the laser marking head 4 from being bumped and also serve as heat insulation protection. The protective cover 2 is always ventilated to form an air flow and a positive pressure protection in the protective cover 2, which can protect the protective cover 2 from dust and also ventilate and cool the laser head.

[0022] As shown in the figure, Figs. 1-3 As shown in the figure, the identification scanning mechanism includes a 3D camera 3, the 3D camera 3 is arranged in the protective cover 2, and an opening aligned with the 3D camera 3 is arranged on the side wall of the protective cover 2 to ensure that the 3D camera 3 can shoot the wheel image outside the protective cover 2. The 3D camera 3 is used to scan the wheel marking surface to generate wheel contour information in real time. The scanning system can scan the wheel marking surface at a distance and is provided with a protective cover, which can avoid the influence of heat radiation on the 3D camera 3.

[0023] As shown in the figure, Figs. 1-3 As shown in the figure, the primer spraying mechanism mainly includes a spray gun 5, the spray gun 5 is arranged in the protective cover 2, and an opening aligned with the spray gun 5 is arranged on the side wall of the protective cover 2 to ensure that the spray gun 5 can spray primer on the surface of the wheel outside the protective cover 2. After the high-temperature-resistant white primer is sprayed on the surface of the wheel, the laser marking head 4 is used for marking.

[0024] As shown in the figure, Figs. 1-3 As shown in the figure, the hot wheel laser marking device further comprises a high-pressure blowing mechanism for removing the oxide skin on the wheel, and the high-pressure blowing mechanism is arranged on the industrial robot 1. The high-pressure blowing mechanism mainly includes a jet nozzle, the jet nozzle is connected with an air compressor located outside the industrial robot 1, the jet nozzle is arranged in the protective cover 2, and an opening aligned with the jet nozzle is arranged on the side wall of the protective cover 2 to ensure that the jet nozzle can spray high-pressure air on the surface of the wheel outside the protective cover 2.

[0025] The process flow of the hot-state wheel laser marking device with the above structure is as follows:

[0026] 1) The robot laser marking system receives the data to be marked;

[0027] 2) The wheels are conveyed downstream after exiting the tempering furnace. When the steel signal sensor detects the wheels, it sends a "wheel in position" signal to the roller conveyor control system. The roller conveyor control system then stops the roller conveyor and sends an interlock signal.

[0028] 3) After receiving the roller conveyor interlock signal, the equipment system first identifies the contour of the wheel by the scanning mechanism, and then feeds back the identified and positioned contour to the robot system.

[0029] 4) The robot drives the high-pressure blowing mechanism to remove the oxide scale from the marking surface with high-pressure air. After the air blowing action is completed, it rotates to the primer spray gun 5 to start spraying. The white primer covers the wheel marking surface.

[0030] 5) Once the primer marking is complete, switch to laser marking head 4. Laser marking head 4 starts working and etches the marking content onto the marking surface that has been covered with white primer.

[0031] 6) Once the identification is completed and verified (scan the QR code, handle any abnormal alarms), de-interlock and return to the standby position;

[0032] 7) Waiting for the next wheel to be marked.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
