Embodiment approach

[0030] Turn on the lighter detection device, first the system will automatically reset. After resetting, adjust the nut 9 to meet the needs of measuring lighters at different heights. The lighter to be tested is placed on the base 11 so that the pressure rod 1 and the button of the lighter remain about 1 cm away. As shown in Figure 1, after pressing the button of the measuring instrument, the microprocessor (TMS2407) sends a pulse signal through the driver to make the stepping motor 5 drive the push rod to move downward, and the pressing rod presses the button of the lighter to ignite the lighter. During the process from pressing the button of the measuring instrument to igniting the lighter, the differential signal output by the S-type tension pressure sensor 2 (N-WL1) is amplified by the transmitter (CYB1151), denoised and then input to the analog-to-digital conversion (AD574), AD574 The voltage signal reflecting the pressure change is converted, and the AD574 and the micro...

Abstract

This invention discloses one lighter button pressure and its pressure and displacement character curve test device, which comprises rack, displacement sensor, step motor, push bar, S shape pressure sensor, pressure bar and process circuit, wherein, the step motor is fixed onto rack with adjusting position; the step motor with whirl bar converts the rotation move into line move to fulfill button press operation through S shape pressure sensor and press push bar; the displacement sensor is to adopt round grating coder to realize button displacement measurement.

Description

technical field [0001] The invention relates to a lighter detecting device, in particular to a lighter pressing force and a pressing force and displacement characteristic curve detecting device. Background technique [0002] Lighter is a commodity widely used in daily life and is in great demand. It is also one of the main export commodities of our country. But since 2002, the export of lighters encountered technical barriers to trade. According to the "CR Act" passed by the European Union in May 2002 and the new CR Act passed in June 2006, lighters exported from my country must be equipped with safety locks that prevent children from opening them. Since most of the safety lock technologies have been patented by the European Union and North American countries, if domestic enterprises adopt safety lock solutions, it will inevitably lead to a substantial increase in the cost of their products due to intellectual property rights, thus losing competitiveness. At present, the c...
