Bluetooth leather sheath keyboard dormancy magnet test device and test method

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.

Description

technical field [0001] The invention belongs to the field of electronic product accessory manufacturing, and in particular relates to a test device for a dormant magnet of a bluetooth leather case keyboard, and also relates to a test method for a dormant magnet of a bluetooth leather case keyboard. Background technique [0002] With the continuous development of electronic products, smart handheld terminals are more and more widely used in people's lives. Common smart handheld terminals usually include smartphones and tablet computers, and as the processing chips and memory chips of smart terminal applications such as mobile phones and tablet computers become more and more powerful, mobile phones and tablet computers can basically handle things that ordinary computers can handle. Can handle, especially tablet computer, even has the trend of replacing traditional computer. [0003] The design display screen of the tablet computer is exposed, and the screen is easy to be dama...

AI Technical Summary

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 trigger of the Hull switch on the tablet, the tablet cannot enter sleep mode, which seriously affects the battery life of the tablet.

[0005] In addition, although manufacturers of Bluetooth leather case keyboards have used IPAD tablets and leather case keyboards for actual group testing during shipment inspections, the defective reworked repairs waste a lot of manpower and materials, especially the rework of plastic case leather case keyboards combined with ultrasonic waves. It is very difficult to disassemble and will cause all plastic shells to be scrapped
