Problems solved by technology

[0004] At this stage, the production process of bluetooth leather keyboard is becoming more and more mature, but the overall assembly yield is not very satisfactory
In particular, the dormant magnet on the Bluetooth leather case keyboard is not properly assembled or reversed due to bad reasons, resulting in the closure of the tablet and the leather case keyboard, due to the reverse polarity of the Bluetooth leather case keyboard magnet or improper assembly and insufficient magnetic induction of the magnet itself. Instead of flipping the internal trigge

Embodiment Construction

[0031] Below, the present invention will be described in further detail in conjunction with the accompanying drawings.

[0032] This embodiment discloses a bluetooth leather case keyboard dormant magnet test device, the test device is used to test the dormant magnet of the bluetooth leather case keyboard, especially can be applied to the semi-finished leather case keyboard to be tested with the dormant magnet assembled The dormant magnet assembly is tested.

[0033] Such as Figure 1-5 As shown, the test device includes a substrate 1 , a development board 2 , a liquid crystal display module 3 , a Hall sensor 4 and an LED indicator 5 . Wherein, the substrate 1 is a transparent substrate made of transparent material. Development board 2 is an Arduino Mega2560 development board with 54 digital input and output channels, which is suitable for the design that requires a large number of IO interfaces. The processor core is ATmega2560, and it has 54 digital input / output ports (15 o...

Abstract

The invention discloses a bluetooth leather sheath keyboard dormancy magnet test device and a test method. A placing area used for positioning and placing a bluetooth leather sheath keyboard is arranged on a substrate, Hall sensors are arranged in the area and the arrangement positions of the Hall sensors correspond to the standard assembling position of each dormancy magnet. When a semi-finishedproduct to be tested is placed in the placing area, the Hall sensors detect the magnetic induction intensity of each position, simultaneously detection signals are processed and compared through a preset test program in a development board, a result is output and whether the dormancy magnet of each position is assembled qualifiedly is determined. In the test method, the upper and lower limits of the magnetic induction intensity of the dormancy magnet at each position are calibrated and are written into the test program, and the bluetooth leather sheath keyboard semi-finished product to be tested with the assembled dormancy magnet is placed in the placing area so that a test can be completed, and whether the polarity of the dormancy magnet is reversed, assembling is in place, and the magnetic induction intensity accords with a flat plate dormancy requirement are detected before the ultrasonic assembling of a shell or screw locking.
