Ultrasonic detecting system and method

Abstract

The invention discloses an ultrasonic detecting system and method. The ultrasonic detecting system is used for detecting lithium batteries and comprises a detecting portion, a transmitting portion, a sorting mechanism, wherein the detecting portion is used for detecting swelling of the lithium batteries, the transmitting portion is used for bearing and moving the lithium batteries, the transmitting portion is further connected with the detecting portion, and the sorting mechanism is arranged above the transmitting portion, connected with the detecting portion and used for sorting the lithium batteries with the swelling. The ultrasonic detecting system has the advantages and the beneficial effects of achieving a non-contact type ultrasonic detecting effect and having high flexibility, strong penetrating power, good directivity, quick detecting speed, low cost, relatively simple equipment and no harm to a human body. The ultrasonic detecting system also has the advantages of avoiding coupling agent, keeping longer distance with an object to be detected, having a simple and convenient detection process, improving the automation degree of lithium battery detection, greatly saving labor consumption of a battery swelling detecting process, reducing production cost, being beneficial to solving the problem that the efficiency and the accuracy are not high in manual product detection and greatly improving the production efficiency.

Description

technical field [0001] The invention relates to the field of detection, in particular to an ultrasonic detection system and method. Background technique [0002] Lithium battery is a new type of rechargeable battery.
