Abstract

The invention discloses electromagnetic heater to touch bond structure.Electromagnetic heater touches bond structure, including substrate, and substrate is provided with IC, LED, charactron and the membrane keyboard induction region electrically connected, membrane keyboard induction region is provided with copper sheet, copper sheet surface is provided with sensing extension, and sensing extension is resistance or electric capacity, and resistance or electric capacity electrically connect with copper sheet short circuit.By setting copper sheet, and be sticked on copper sheet resistance or electric capacity in induction region, induction region is raised in realization, is substituted spring, be ensure that precision and the sensitivity of sensing, while the structure can be produced by mechanical automation, and production efficiency greatly improves.

Description

Electromagnetic heater touches bond structure
Technical field
The present invention relates to membrane keyboard field, more particularly to electromagnetic heater touches bond structure.
Background technology
The membrane keyboard principle of electromagnetic heater is, by setting induction region on substrate, when human contact's induction zone Corresponding to domain during micro-crystal plate, the change of induction region capacitor's capacity, touch control is realized, in order to realize the sensitivity of sensing and accurate Degree improves, and conventional spring is placed on induction region, raises sensing height so that the distance of reaction of induction region and micro-crystal plate becomes It is small.
But easily wound in transportation in spring, cut-out spring needs artificial progress, cumbersome, time-consuming to take Power, and spring installation is also required to using manually installed, and efficiency is low.
The content of the invention
It is an object of the invention to provide it is a kind of without spring, simplify, can industrial automation production electromagnetic heater touch Touch bond structure.
To achieve the above object, the present invention adopts the following technical scheme that, electromagnetic heater touches bond structure, including base Plate, substrate are provided with IC, LED, charactron and the membrane keyboard induction region electrically connected, and membrane keyboard induction region is provided with copper sheet, Copper sheet surface is provided with sensing extension, the copper sheet short circuit electrical connection of sensing extension.By setting copper sheet in induction region, and in copper Be sticked sensing extension on skin, and realization raises induction region, substitutes spring, ensure that precision and the sensitivity of sensing, The structure can be produced by mechanical automation simultaneously, and production efficiency greatly improves.
In some embodiments, a diameter of 10~15mm of copper sheet.Copper sheet diameter is arranged to 10~15mm, it is ensured that sensing model Enclose.
In some embodiments, substrate is single sided board.
In some embodiments, LED is paster LED.LED uses paster LED so that projecting height is relatively low, whole Body structure is more simplified, is frivolous.
In some embodiments, charactron is " 8 " word pattern that surface-mount digital tube or paster LED form.Charactron is " 8 " word pattern of surface-mount digital tube or paster LED composition so that charactron projecting height is relatively low, and overall structure is more simplified, gently It is thin.
In some embodiments, it is resistance, electric capacity, inductance or magnetic bead to sense extension.
In some embodiments, it is four to sense extension, and four sensing extension annulars are set.Four sensings are set Extension, annular are set, it is ensured that induction area, are ensured sensitivity and accuracy, prevented maloperation.
Beneficial effects of the present invention are:Electromagnetic heater of the present invention touches bond structure, by being set in substrate induction region Copper sheet is put, and be sticked on copper sheet resistance or electric capacity, the raising of sensed position is realized, substitutes spring so that overall structure is more Add and simplify, be frivolous, and mechanical automation integral installation can be realized, substantially increase production efficiency.
Brief description of the drawings
Fig. 1 is the structural representation that electromagnetic heater of the present invention touches bond structure;
Fig. 2 is Fig. 1 schematic diagram of facing upward.
Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Figure 1, 2, electromagnetic heater touches bond structure, including substrate 1, substrate be provided with electrically connect IC2, LED 3, charactron 4 and membrane keyboard induction region 5, membrane keyboard induction region 5, which is sticked, copper sheet 6, and the surface of copper sheet 6 is provided with sensing Extension 7, sensing extension 7 are resistance or electric capacity, and resistance or electric capacity electrically connect with the short circuit of copper sheet 6.
The circular copper sheet 6 for diameter 12mm of copper sheet 6, be sticked on circular copper sheet 6 four resistance or electric capacity, four resistance or Electric capacity is distributed in a ring, it is ensured that sensing precision.
LED 3 is paster LED, and charactron 4 is " 8 " word pattern that surface-mount digital tube or paster LED form.The He of LED 3 Charactron 4 is installed using patch form so that assembling is highly relatively low, and overall structure is simplified, frivolous.
Touch bond structure to be arranged on below micro-crystal plate directly against near, the copper sheet 6 set on touching induction region 5 and sensing Induction range is become big by extension 7, and distance of reaction shortens, and improves sensitivity and the precision of sensing, avoids maloperation,
By said structure design, all electronic components on substrate can realize full-automatic peace by SMT technologies Dress, without manual installation, substantially increases production efficiency.
Electromagnetic heater of the present invention touches bond structure, by setting copper sheet in substrate induction region, and is pasted on copper sheet If resistance or electric capacity, the raising of sensed position is realized, substitutes spring so that overall structure is more simplified, be frivolous, and can be realized Mechanical automation integral installation, substantially increases production efficiency.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention Enclose.
