Abstract

Methods, systems, and devices for manufacturing a wearable ring device are described. The manufacturing assembly may rotate, by a rotational component, an inner housing member of the wearable ring device to a radial orientation based on an optical alignment process. A positioning component of the manufacturing assembly may insert and align an optical component of a flexible circuit assembly into at least one aperture of the inner housing member by moving the flexible circuit assembly from a first position adjacent to the inner housing member to a second position on the inner housing member. The manufacturing assembly may secure one or more edges of the flexible circuit assembly onto the inner housing member using a plurality of arms of the positioning component and apply, by an automatic adhesive dispensing device of the manufacturing assembly, a polymeric material to adhere the flexible circuit assembly to the inner housing member.

Description

FIELD OF TECHNOLOGY The following relates to wearable devices and data processing, including flex wrap circuit assembly techniques. BACKGROUND Some wearable devices may be configured to collect data from users. In some cases, some wearable devices may perform various actions, such as providing certain health insights to users, based on acquired physiological data in order to assist the user with improving their overall health. Methods for manufacturing wearable devices may include manually assembling each individual component of the wearable device. However, techniques used in such manufacturing processes may lead to irregularities in shape, may be costly, may be difficult to position to create a consistent product, among other potential deficiencies.

DETAILED DESCRIPTION An individual may use a wearable device (e.g., a wearable ring device) to collect, monitor, and track physiological data of the individual based on sensor measurements of the wearable ring device. Examples of physiological data may include temperature data, heart rate data, photoplethysmography (PPG) data, and the like. The physiological data collected, monitored, and tracked via the wearable ring device may be used to gain health insights about the user. In some cases, one or more sensors of the wearable ring device may be located between an inner housing of the wearable ring device and an outer housing of the wearable ring device. Separate optical components (e.g., lenses, reflectors, prisms, microprisms, micro lenses arrays, angular filters, and the like) may be included in the wearable ring device to enhance the functionality of the one or more sensor optoelectronic components (e.g., components such as light emitting elements and light detecting elements). However, integrating the optical components into the wearable ring device with adequate accuracy and robustness may be challenging due to the size of the components and the scale of the integration. The optical components may need to be manually and properly positioned within the wearable ring devices to align with the one or more sensor optoelectronic components or apertures or other physical features of the wearable device. For example, the optical components may need to be manually and properly positioned within the wearable ring devices to align with the one or more sensor optoelectronic components, resulting in manufacturing complexities or, if misaligned, manufacturing deformities. In such cases, manufacturing the optical components to adhere to the wearable ring device may be expensive and time consuming due to the need to accurately and manually place the optical components onto or within the wearable ring device. In this regard, inefficiently manufacturing the wearable ring device may result in inaccurate placement of the optical components that may result in unreliable physiological measurements, increased battery consumption, increased processing power at the wearable, among other technical challenges.
