Description

Technical Field

[0001] The utility model relates to the technical field of detection and screening, and more specifically, to a device for detecting and accurately screening the shell size of an earphone product. Background Art

[0002] Headphones receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ear. They can be separated from the media player and connected using only a plug, allowing you to listen to the audio without disturbing others. They can also block out ambient sounds, making them very helpful for people using them in noisy environments such as recording studios, bars, while traveling, and while exercising. Among the components of headphones, the headphone housing is a crucial protective component.

[0003] In the plastics processing industry, CNC machining of headphone casings requires precise dimensions and high production volumes. Traditionally, this type of product is processed manually, after CNC machining, by placing the product on a custom hardware fixture for thorough inspection, one by one, to verify that the CNC-machined hole dimensions, position, and appearance meet quality requirements. This traditional processing method carries safety risks, is inefficient, prone to fatigue, and results in unstable operation. Given these shortcomings, we urgently need to develop a new, safe, efficient, labor-saving, and easy-to-use automated inspection and screening device. Utility Model Content
