Problems solved by technology

[0003] In the production method of this kind of opposing photointerrupter, after the photodetector and photoreceiver are packaged, it still needs to go through complicated procedures such as plug-in and tin furnace. The whole process takes a lot of time and costs a lot, and The process of going through the tin furnace must make the vertical photointerrupter withstand high temperature, which may cause damage to the components and affect the reliability of the finished product

Embodiment Construction

[0049] In the embodiment of the present invention, the signal source and the detector are directly packaged on the metal support, and the signal source and the detector are formed into a parallel opposing structure by bending. Anyone with ordinary knowledge in the technical field can cooperate with it If necessary, change the material, shape and related design parameters of the metal bracket to meet various application product specifications and cost considerations.

[0050] Please refer to figure 1 , an exploded view of the first embodiment of the present invention, the opposite photointerrupter in the figure can be divided into several parts, namely the signal source 102, the receiver 104, the housing 106 and the opposite light shield 108. The signal source 102 and the receiver 104 are in a parallel opposing structure, so that the receiver 104 can receive the signal sent by the signal source 102 . There are two holes 110 on the opposite shading cover 108, corresponding to t...

Abstract

The invention relates to an opposite-type optical breaker, comprising a receiver, a signal source and a metal bracket. The signal source and the receiver are arranged in parallel and oppositely; the metal bracket comprises a first vertical part, a second vertical part and a horizontal part; the first vertical part and the second vertical part are respectively used for installing the signal source and the receiver. The invention has the manufacturing method that the receiver and the signal source are encapsulated on the metal bracket, and then the molding is completed through the steps of bending, cutting, outer shell molding by ejecting plastic, etc.

Description

technical field [0001] The present invention relates to an opposed photointerrupter device and a manufacturing method, and in particular to a substrate-free photointerrupter device and a manufacturing method. Background technique [0002] The vertical photointerrupter uses the detection of the presence or absence of light signals as a switch mechanism, and has a wide range of applications. The current development trend of vertical photointerrupters is small size, low cost and high precision. The production method of the common opposed photointerrupter is to install the packaged photodetector and photoreceiver on a substrate as a plug-in, and then enter the solder furnace step to solder the photodetector and photoreceiver on the Finally, it is combined with the light shield to complete the finished product of the opposing photointerrupter. [0003] In the production method of this kind of opposing photointerrupter, after the photodetector and photoreceiver are packaged, it ...
