Thermostat error-prevention visual detection and recognition device and method

Abstract

The invention discloses a thermostat error-prevention visual detection and recognition device comprising a cabinet and an operation platform which is arranged in the middle of the cabinet. The devicealso comprises a visual imaging system, a visual processing system, a detection clamp platform and a detection displayer. The visual imaging system comprises a side camera unit and an upper camera unit, and the side camera unit and the upper camera unit are arranged at different perspectives of the thermostat. The visual processing system is arranged between the visual imaging system and the detection displayer. The invention also discloses a thermostat error-prevention visual detection method. According to the thermostat error-prevention visual detection and recognition device, multiple different detection points are simultaneously photographed through the dual-angle arranged CCD camera units and the small change of the thermostat is recognized so that misrecognition caused by personnel visual error and fatigue can be avoided, the correct recognition rate can be 100%, the defective products can be effectively distinguished, the mark detection time for each product is within 0.5s and thus the efficiency of detection and recognition can be greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of automobile thermostat detection, and more specifically relates to a thermostat error-proofing visual detection and recognition device and method. Background technique [0002] Automobile thermostat is an important part of auto parts. When the engine is working at high temperature, the engine is prone to overheating, which may damage the engine or even burn it. However, working at low temperature will greatly reduce the effect of fuel atomization, resulting in insufficient fuel combustion. life. Therefore, a thermostat is usually used to regulate the temperature of the engine. The thermostat automatically adjusts the amount of water entering the radiator according to the change of the coolant temperature, and also changes the water circulation range, thereby adjusting the heat dissipation capacity of the cooling system and ensuring that the engine works within a suitable temperature range. The "mini-cir...

Problems solved by technology

At present, domestic small and medium-sized enterprises mainly rely on manual inspection, the accuracy of identification is not high, and people's eyes are prone to fatigue, and the rate of missed inspection is high, resulting in a substandard product pass rate

In addition, manual inspection is slow, affecting the normal assembly schedule of OEMs, resulting in a continuous decline in customer satisfaction
