[0001] The invention relates to the technical field of laser marking, and in particular to a sensor laser marking device. Background Art

[0002] After the sensor is produced, it needs to be marked on its shell by laser ablation. Various laser marking devices are proposed in the prior art. For example, the Chinese invention patent application with publication number CN111151891A proposes an automated laser marking device for automobile air quality sensors. The workpiece of the laser marking device is conveyed to the bottom of the laser marking mechanism via a conveyor belt for marking one by one, which greatly improves the processing efficiency of the product. The conveyor belt is programmed to move at set time intervals, which helps to ensure the accuracy of marking. The laser marking mechanism is provided with an exhaust mechanism, which is connected to a negative pressure power source. The exhaust mechanism includes an exhaust hood, which is located next to the laser marking head and can discharge the exhaust gas generated during laser marking in time to avoid the accumulation of exhaust gas in the workshop. For example, the Chinese utility model patent with publication number CN209647853U proposes a sensor laser welding and marking all-in-one machine. This all-in-one machine can complete the process of loading the sensor on the welding fixture onto the marking fixture while completing the process of unloading the sensor on the marking fixture, which is more convenient and efficient; it avoids human body contact with the sensor that heats up after welding, thereby increasing safety.

[0003] However, the laser marking equipment of the above-mentioned prior art mainly marks the plane of the sensor, and cannot mark the circumference of the curved surface of the cylindrical sensor.
