CN209310826U 一种光电编码器用发光元件 有权 转让

一种光电编码器用发光元件
摘要：
本实用新型涉及一种光电编码器用发光元件，包括电路板、主轴、码盘以及底座，底座下表面开有安装通道，安装通道内设有镶嵌件，镶嵌件相对电路板一侧设有透镜，镶嵌件下表面开有安装槽，安装槽内紧密连接有一体式发光管，一体式发光管与透镜之间有间距，由于一体式发光管外套接有具有透镜的镶嵌件，经过两次汇聚，提高发光元件照射在光电转换芯片上的平行度，由于一体式发光管外设置一层透镜，缩短发光元件与光电转换芯片间的距离，有效提高发光元件对光电转换芯片的照射面积，有效改善原始信号质量，除此之外，一体式发光管紧密插接于镶嵌件内部，简化安装工艺，提高生产效率。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model relates to a light-emitting element for a photoelectric encoder. The device comprises a circuit board, a spindle, a coded disc and a base, a mounting channel is formed in the lower surface of the base; an insert is arranged in the mounting channel; a lens is arranged on one side of the insert opposite to the circuit board; a mounting groove is formed in the lower surface of the insert; an integrated light-emitting tube is tightly connected in the mounting groove; a gap is formed between the integrated light-emitting tube and the lens; the insert with the lens is sleeved outside the integrated light-emitting tube; two-time convergence, the parallelism of the light-emitting element irradiated on the photoelectric conversion chip is improved; due to the fact that the lens isarranged outside the integrated light-emitting tube, the distance between the light-emitting element and the photoelectric conversion chip is shortened, the irradiation area of the light-emitting element to the photoelectric conversion chip is effectively increased, the original signal quality is effectively improved, in addition, the integrated light-emitting tube is tightly inserted into the insert, the installation process is simplified, and the production efficiency is improved.
