Problems solved by technology

Locking the lens through the thread will make the thread structure occupy a certain volume, and when the lens has an inclination angle relative to the image sensor (Sensor), it will cause the problem of out of focus, but the inclination angle cannot be made due to the limitation of the thread structure Fine-tuning the level, so that the lens i

Example Embodiment

[0037] The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0038] See figure 1 Shown is a three-dimensional schematic diagram of an embodiment of the lens driving device of the present invention. The lens driving device of this embodiment includes a bearing seat 20 for bearing a lens cylinder 10, and the bearing seat 20 is accommodated in a frame 60 with a hollow structure. The frame 60 can also be covered with an upper cover 61, the outer periphery of the bearing base 20 is covered with a coil assembly 62, and the four permanent magnets 63 corresponding to the coil assembly 62 are arranged outside the coil assembly 62, on the bearing base 20 A set of elastic components 64 are connected to each of the lower and lower sides, which can suspend the supporting base 20 in the center of the frame 60, and an image sensor 30 is arranged under the frame 60.

[0039] The coil assembly 62 ca...

Abstract

The invention relates to a lens structure of a micro-lens driving device, which comprises a lens cylinder consisting of at least one lens and a lens support part, the lens cylinder and a carrying seat further constitute a lens unit, the lens and the lens support part have no thread structure, and the lens is adhered in the lens support part by a binding agent; and the bearing seat is in the shape of a hollow cylinder, the lens cylinder can be accommodated in the carrying seat, the lens cylinder and the carrying seat also have no thread structure, and the lens cylinder is adhered in the carrying seat by the binding agent, thereby solving the volume occupied by the thread structure, being more miniaturized, and further solving the problem of contact friction loss caused by the thread structure.

Description

technical field [0001] The present invention relates to a lens structure of a miniature lens driving device and its manufacturing method, in particular to a lens unit with a threadless structure and its manufacturing method, which can specifically reduce the structure of the lens, and has the ability to finely adjust the tilt of the lens during the process and focus function. Background technique [0002] Press, the micro lens driving device is mainly to drive the focusing lens to move linearly along the optical axis to focus the image light on the image sensor. It has been widely used in electronic devices with camera or photography functions, such as mobile phones, etc. There are many related driving modes for the lens driving device, such as patent application documents: Japanese Patent Application No. 2008-129597, claiming the priority of Chinese Invention No. 200610157001.2, which discloses a structure that uses a stepping motor to drive the lens to focus , a method in...
