Acceleration sensor

Abstract

The invention provides an acceleration sensor which comprises a rotating shaft arranged on a main frame, a rotating arm arranged on the rotating shaft, and an item placing frame rotationally arranged on the rotating arm and used for placing a plurality of members to be detected. The rotating shaft rotates itself to form a first rotary surface, the item placing frame rotates itself to form a second rotary surface, and the first rotary surface and the second rotary surface intersect with each other. By adopting the structure in which the rotating shaft and the item placing frame capable of rotating itself are matched, rotation lifting of each point in a three-dimensional space is easy to realize, and acceleration sensors in the members to be detected can be tested. The item placing frame can be used for placing a plurality of members to be detected according to actual needs, and can adapt to hand-held devices of various models and flat computers. The acceleration sensor is simple in structure, convenient to use and high in detection efficiency.

Description

technical field [0001] The invention relates to a hand-held device or a tablet computer production detection device, in particular to an acceleration sensor. Background technique [0002] The terms acceleration sensor and electronic compass may be unfamiliar to you, but if you mention G-sensor and E-compass in the consumer market in recent years, it can be said to be very famous, because any handheld product or human-computer interaction interface will Add this feature. After the handheld device or tablet computer is manufactured, it is necessary to test the acceleration sensor for each product produced to test whether it is intact and whether the program can run, etc. [0003] At present, various manufacturers mainly detect the three-dimensional motion of the handheld device or the tablet computer manually, which is time-consuming and laborious, and the detection has certain difficulties. Some manufacturers also use some simple devices to carry out this test. These simple...

Problems solved by technology

[0003] At present, manufacturers mainly detect the three-dimensional motion of handheld devices or tablet computers manually, which is time-consuming and labor-intensive, and there are certain difficulties in detection

Some manufacturers also use some simple devices to carry out this test. These simple devices generally use a structure that cooperates with a lifting frame and a horizontal rotating table. However, these simple devices can only detect a few handheld devices and tablet computers, and can detect up to four. The quantity is small, and only the front side of the handheld device and tablet computer can be detected. To detect the other side, the handheld device and tablet computer need to be reversed, which is time-consuming and laborious, and it is difficult to meet the production needs
