[0002] The protector is a thermal protection element made of bimetallic strip, which is widely used in various heat generating household appliances such as motors and electrical appliances. When the temperature rises to the action temperature value, the bimetallic strip generates internal stress and quickly acts to open the contact, thereby achieving the purpose of cutting off the circuit and playing the role of thermal protection.

[0035] Working principle:

[0036] Firstly, the detection time of the protector put into the oil tank is set by the man-machine control panel 16. After the equipment is started, the feeding position tray 20 in the feeding mechanism is conveyed along the feeding guide rail 17 to the designated position, and is full of the protector to be detected. When the detection of the previous batch of protectors is completed and discharged, the new feeding position tray 20 is ready for the next round of detection.

[0037] The PLC controller 70 is responsible for commanding the operation of the entire equipment. When the feeding position tray 20 reaches the designated position, the PLC control motor drives the transmission cylinder 41, so that the moving trolley 14 moves to the position along the moving guide rail, and moves the feeding position tray 20 to above the designated oil tank opening through the positioning cylinder. Then, the moving trolley 14 puts the feeding position tray 20 into the oil tank for detection.

[0038] The oil tank control system is composed of a PLC controller 70, a servo driver 74, a heating pump solid-state relay and a cooling pump contactor 75. The PLC controller 70 controls the servo driver 74 according to the set temperature instruction, and the servo driver 74 controls the solid-state relay of the oil tank heating pump and the cooling pump contactor 75 to realize the heating or cooling operation of the oil tank. The four oil tanks are low-temperature tank, high-temperature tank, low-temperature return tank and high-temperature return tank, and the protector will be detected in these tanks in turn.

[0039] The detection mechanism includes a PLC, a detection base plate, a detection assembly 6215 and a detection cylinder 22. When the protector is placed in the oil tank for a predetermined time, the PLC controls the detection cylinder 22 to drive the detection assembly 6215 to move above the protector to be detected, detects the on-off state of the protector, and feeds back the detection result to the man-machine control panel 16 for display.

[0040] After the test is completed, the moving trolley 14 again grasps the feeding position tray 20 to the next oil tank for detection, until all the tests in the four oil tanks are completed. At this time, the protector to be detected is transferred to the sorting discharge tray 9 for sorting.

[0041] The sorting mechanism sorts out the defective products according to the detection results on the man-machine control panel 16, and puts the low-temperature products, high-temperature products, low-temperature return products and high-temperature return products into the corresponding defective product boxes. The defective product boxes correspond to different types of defective products.

[0042] Finally, the protector after sorting is placed on the discharge position tray, and the discharge position tray is conveyed along the discharge guide rail 1 to the discharge base plate, completing the entire detection process.

[0043] In addition, the stirring mechanism 10 continuously stirs the silicone oil in the oil tank to maintain a uniform and constant temperature state in the oil tank. The air source two-connection piece 65 placed on the side of the machine body frame 18 is used in the pneumatic system to ensure the quality and stability of the compressed air. The Forma wheel arranged below the machine body frame 18 facilitates the movement and positioning of the equipment, ensuring the smooth operation of the production line.
