在现代社会中，耳机已经成为人们日常生活中必不可少的一部分。无论是在工作、娱乐还是运动中，耳机都能给我们带来极大的便利和享受。但是，如果耳机的质量无法得到保证，那么使用起来就会产生很多问题。其中一个重要的问题就是耳机的pin脚共面度。

If the coplanarity is not reached, then it will be tilted during insertion, resulting in poor sound quality, loose and easy to fall off and other problems. Therefore, the coplanarity of the pin of the headset has a very important impact on the use of headphones and life, and need to be tested.

Detection needs:

Identify if the pin on the bottom of the headset is in the same plane.

Detection programme:

Using the POMEAS Laser Contour Sensor, the laser scanning and image processing technology obtains three-dimensional information on the surface of the headset and accurately determines whether the pin feet are in the same plane.

Programme strengths:

first. High Precision

The laser profile sensor can achieve micron-level accuracy, which can more accurately determine the coplanarity of the headset pin feet, avoiding the use of problems caused by errors.

Second, fast and efficient

The laser profile sensor can scan and analyse the headphone plug in a very short time, greatly improving the inspection efficiency.

third, High automation

Laser profile sensors allow for automated inspection without human intervention, reducing human interference. This can greatly improve the accuracy and stability of detection.
