An image module positioning jig and method thereof

Abstract

The invention relates to an image module positioning tool and method. The tool comprises a gland, at least one motion briquetting and a supporting desk. The motion briquetting is installed on the supporting desk, and the gland and the supporting desk are pressed together; the supporting desk and the gland are pressed to complete positioning of each element of at least one closed loop type motor, including pressing the motor mover of the closed loop type motor to the bottom of the closed loop type motor, and meanwhile guaranteeing the flatness of other elements in an image module.

Description

technical field [0001] The invention relates to an image module positioning jig, in particular to an image module positioning jig and method suitable for positioning each component of the image module before focusing, including a closed-loop motor mover. Background technique [0002] The closed-loop motor lens has become a rising star in the camera module industry with its "extremely fast focusing" and "excellent low light" as its selling points and highlights. [0003] From the perspective of technology leadership, closed-loop motors have several advantages over ordinary action motors: First, low power consumption. The closed-loop motor puts the lens in the middle of the motor, while the ordinary motor is designed at the bottom. Thanks to this structural design, the power consumption of the closed-loop motor is low. Theoretically, the motor moves 100μm, and the ordinary motor needs to consume 40mA, while the closed-loop motor only needs 15mA. Second, the focus accuracy is...

[0004] However, compared to the traditional motors in use, the use of closed-loop motors does not provide consumers with sufficient user experience due to the increase in cost, which in turn limits the development of closed-loop motors in camera modules.
