Preparation process of infrared receiving head with large receiving angle for air conditioner

Abstract

The invention discloses a preparation process of an infrared receiving head with a large receiving angle for an air conditioner. The preparation process comprises the following steps: forming a first glue locking through hole in a substrate; a chip set is fixedly arranged on the upper surface of the substrate; metal pins are arranged on one side of the substrate; packaging a colloid on the upper surface of the substrate; a semispherical receiving surface is fixedly arranged at the top end of the rubber body and is integrally formed with the rubber body; a shielding shell is arranged on the periphery of the colloid. The packaging glue can permeate into the glue locking through hole during packaging, so that the connection between the packaging layer and the substrate after the packaging glue is cured is firmer, the function failure of the infrared receiving head caused by looseness between the infrared receiving head and the packaging layer is prevented, the yield is improved, and the service life is prolonged; the hemispherical receiving surface is arranged, so that the receiving area is increased, the receiving angle is increased, and the receiving effect is better; and the shielding shell is arranged to shield interference signals, so that the anti-interference capability is enhanced, and the effects of large receiving angle, good receiving effect, strong anti-interference capability and high production efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of infrared receiving heads, in particular to a preparation process of an infrared receiving head for an air conditioner with a large receiving angle. Background technique [0002] In today's society, air conditioners have gradually become one of the household appliances that every household needs, and the normal use of air conditioners requires the installation of infrared receivers to receive infrared rays from the remote control and realize infrared remote control functions. At present, in the infrared receiving head of the prior art, the entire support is packaged by welding the infrared receiving device on the support. In the existing infrared receiving head bracket, after encapsulation, the connection between the bracket and the encapsulation layer is not reliable, and the bracket may become loose after a long time of use, leading to disconnection of the lead wire, which makes the infrared receiving he...

AI Technical Summary

Problems solved by technology

The existing infrared receiving head bracket, after packaging, the connection between the bracket and the packaging layer is not reliable, and the bracket may become loose after a long time of use, resulting in disconnection of the lead wires, invalidating the infrared receiving head, and reducing the service life

And this kind of infrared receiving head also has the shortcomings of small receiving angle and poor anti-interference ability, so when the distance is a little far or the angle is a little bit off, the remote control function of the air conditioner remote control will not work normally, which brings certain problems to the use. Trouble

[0003] Therefore, under the existing technical solutions, the problems of small receiving angle and short service life of the infrared receiving head for air conditioners need to be solved urgently.
