Infrared receiver is something used to receive infrared. This thing has many names, generally called infrared receiver, referred to as receiver, can also be called infrared receiver, infrared receiver tube, infrared receiver module, remote control receiver, etc.
There are many shapes of infrared receivers, but they can be divided into three categories, hemispherical (or dot type), nose bridge type (or tombstone type), and straw hat type. The infrared receiving head is packaged into these shapes to focus the infrared rays, which is the same as the principle of the convex lens to focus the light. After the infrared rays are focused, they are concentrated on a photosensitive element of a PD in the receiving head, and then the signal is amplified and demodulated by the IC.
At present, the infrared receivers on the market can be divided into two main categories from the packaging method: pressure model and potting type. Generally speaking, the nose bridge type belongs to the potting type, and the ball type belongs to the pressure model. In terms of the two packaging processes, the investment in molding equipment is relatively large, and the rubber cake used is more expensive, so the overall price is more expensive; the investment in glue-filling equipment is small, and most of the products made by domestic factories are glue-filled products.
Yihexing automatic high-speed glue filling machine is an upgraded and customized intelligent glue filling production line, which realizes the functions of automatic identification of product model, automatic glue filling, automatic drying, and automatic reflow of tooling. The production line presets MES interface, which is convenient to realize the docking with the system and upload the data. The data covers the production quantity, defect phenomenon, equipment abnormal phenomenon, abnormal time and other data; optional bracket detection imaging system, taking pictures, automatically identifying product types and automatically calling out The glue program enters the glue filling area to take pictures of the later stage, automatically recognizes the glue filling path and performs automatic glue filling, the product is automatically dried, and the tooling is automatically reflowed without manual intervention, thus realizing intelligent production. It reduces the manpower input of the enterprise, liberates the labor productivity, speeds up and improves the production efficiency and product quality of the enterprise, and is widely used in electronic products such as visible light sensors and infrared photosensitive sensors.
