Ultrasonic welding inspection process method and system

Abstract

The invention provides an ultrasonic welding inspection process method and system. The ultrasonic welding inspection process method comprises the following steps: S1, importing a good product image into an X-ray detector to serve as a reference image; s2, putting a to-be-detected sensor wire harness terminal and a connecting sheet assembly into an objective table; s3, moving the objective table on the horizontal plane until the to-be-detected sensor wire harness terminal and connecting piece assembly is moved to the position under the detector; s4, adjusting the defocusing amount and the exposure degree of the X-ray detector, and then using the detector to shoot the to-be-detected sensor wire harness terminal and the connecting piece assembly; s5, transmitting an image shot by the detector into the X-ray detector, comparing the image with the reference image, judging the similarity between the image shot by the detector and the reference image, and outputting an inspection report; and S6, uploading the inspection report to a tracing system and / or locally storing the inspection report. The detection accuracy of the sensor wire harness terminal and the connecting sheet assembly can be improved, so that the convenience of screening out unqualified products can be improved.

Description

technical field [0001] The invention relates to the technical field of wire harness inspection, in particular to an ultrasonic welding inspection process method and system. Background technique [0002] The temperature sensor is a semiconductor device that uses the characteristics of NTC's resistance value changing with temperature to convert non-electrical physical quantities into electrical quantities, so that precise temperature measurement and automatic control can be performed. In recent years, the rapid growth of the new energy industry and the lithium-ion battery industry has driven the rapid growth of the demand for temperature sensors in my country. As the energy density of lithium batteries increases and the safety margin decreases, the core issue is to know the temperature of the lithium battery itself. Therefore, the reliability of the temperature sensor is particularly important. [0003] Multiple single batteries are connected in series or in parallel to form...

Problems solved by technology

[0006] The inventor believes that the existing technology uses the current on-off method to detect the sensor wire harness, but it does not take into account that the current can still be turned on when the wire harness is partially broken, and the test result is still qualified, and there is room for improvement
