薄膜面板按键凸起

更新时间:2016-04-27 点击数:2174

什么是按键凸起?

按键凸起是用压鼓机将面膜层上的键体区域压起。此方法依据材料的自然特性和凸凹特性,有严格的温度和压力要求。

基本形式如下:

(1)框线凸起:开关边缘凸起的时候采用。

(2)平面凸起:整个开关都高于面板表面时采用。

(3)球凸:用于加工球形按键。

(4)框线凸起+球凸:不常用。

  有哪些优点:

(1)增进了薄膜开关外观的装饰效果。

(2)操作者的触觉比较敏感。

(3)准确给定键体的范围。

(4)提高辨认速度。

  重要的设计考虑因素有哪些:

(1)需要专用的模具机加工。

(2)用力过大会减少机械寿命(对于聚碳酸酯面膜来说机械寿命应能操作不少于10万次)。

(3)凸起的聚脂的极限温度为50℃。

(4)凸起高度应不超过材料厚度的1.5倍。

(5)平面凸起应距边缘最少3mm或 5mm。                      

(6)框线凸起的按键距离边缘最少5mm。   


What are the keys raised?

The key is raised by pressing the drum machine will mask layer on the key body region pressure. According to the nature and characteristics of convex and concave material, there are strict requirements for temperature and pressure.

The basic form is as follows:

(1): when the switch line raised by convex edge.

(2): the whole plane uplift are higher than the surface of the panel switch.

(3): convex ball for processing spherical button.

(4) frame line raised + ball convex: not commonly used.

What are the advantages?

(1) to enhance the decorative effect of the appearance of the film switch.

(2) the operator's sense of touch is more sensitive.

(3) the exact range of the given key.

(4) increase the speed of identification.

What are the important design considerations?

(1) die machining special.

(2) reduce the life of the mechanical force over the general assembly (for polycarbonate mask mechanical life should be able to operate for not less than 100 thousand times).

(3) raised the limit temperature of polyester is 50 DEG C.

(4) the bulge height should be 1.5 times less than the thickness of the material.

(5) plane uplift from the edge of at least 3mm or 5mm.

(6) the frame line convex button from the edge of at least 5mm.
