Wearable equipment, optical device, optical module and packaging method of optical module

Abstract

The invention discloses wearable equipment, an optical device, an optical module and a packaging method of the optical module. The packaging method comprises the following steps of providing a substrate loaded with components; forming a cover plate with a light-transmitting area by adopting a double-shot molding, secondary injection molding or rubber coating process; and installing the cover plateon the substrate, enabling the cover plate to protrude towards the side away from the substrate, forming a containing space between the cover plate and the substrate, and containing the components inthe containing space to form the optical module. The forming shape of the cover plate can be flexibly changed, a plane or a curved surface or other complex curved surfaces can be formed on the outersurface of the cover plate, and adaptive adjustment is conducted according to the shape of an equipment shell, so that waste of internal space of equipment is reduced, and miniaturization of the equipment is facilitated. Moreover, the shape of the cover plate can be flexibly changed, the light-transmitting area is arranged on the cover plate, and the shape of the light-transmitting area can also be flexibly changed, so that the flexibility of light path design is improved, and the process cost is low.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a wearable equipment, an optical device, an optical module and a packaging method thereof. Background technique [0002] As people's health awareness continues to increase, more and more smart electronic devices, such as bracelets and watches, choose to integrate optical devices, such as heart rate sensors, which measure the user's heart rate and blood oxygen concentration based on the PPG principle. In the industry, the optical module is generally packaged by potting glue or attaching a glass cover. When it is applied to the whole machine, it is often necessary to design a window on the casing of the device. However, there are the following problems in the way of potting glue or attaching the glass cover: (1) The upper surface of the optical module is generally flat, which cannot well adapt to the situation when the equipment shell is a curved surface, which will ca...
