[0002] Currently, thermal protectors are commonly used safety protection devices in electrical equipment to prevent dangers caused by overheating or overload. During the production process of thermal protectors, marking is required on their housings to identify product information such as production date, model, and batch number. For small thermal protector housings, due to their small size and complex shape, traditional marking machines often struggle to achieve stable and reliable marking results.

[0003] After searching the existing technology, a Chinese patent with publication number CN211516397U was found to disclose an automatic marking machine for thermal protector shells. In this patent, a marking path conveyor track is fixedly installed at the upper end of the conveyor, and a laser marking head marks the workpiece inside the conveyor track. However, during use, it was found that marking on the conveyor can easily cause the workpiece position to be unstable, affecting the marking accuracy. Summary of the Invention

[0050] The vibratory feeder and linear feeder 3 are existing technologies, and will not be described in detail in this embodiment. The specific structure of the linear feeder 3 is described in the linear feeder in patent publication number CN217497534U.

[0051] Specifically, such as Figure 1 and Figure 5-6 As shown, the marking machine for thermal protectors also includes a thermal protector measuring mechanism 10, which includes:

[0052] Telescopic drive mechanism 11 is mounted on the upright frame 4 and is provided with a telescopic rod that can reciprocate in the vertical direction.

[0053] A pair of measuring columns 12 with measuring heads at their ends are fixedly connected to the corresponding telescopic rods of the telescopic drive mechanism 11. The measuring heads are adapted to be driven to make contact with the corresponding contacts of the thermal protector.
