Embodiment 1

[0066] This embodiment provides a light engine assembling equipment, and the light engine structure to be assembled is as follows figure 1 shown. The light engine includes a color combination prism 1 , a first micro display chip 2 , a second micro display chip 3 , a third micro display chip 4 , and an imaging lens 5 respectively mounted on the color combination prism 1 . The color combination prism 1 has a hexahedral structure, the first micro display chip 2 and the third micro display chip 4 are respectively located on opposite sides of the color combination prism 1, and the second micro display chip 3 and the imaging lens 5 are respectively located on the color combination prism 1. In addition, the other two opposite sides of the color combination prism 1 are used as the clamping surfaces for clamping the color combination prism 1 during the assembly process of the light engine. In the specific implementation process, the first micro display chip 2 , the second micro displa...

Embodiment 2

[0097] The difference between this embodiment and Embodiment 1 is that the assembled light engine has two micro display chips, and the corresponding bonding portion includes a first clamping member and a second clamping member. During specific implementation, the two clamping members enclose an L-shaped structure.

Embodiment 3

[0099] The difference between this embodiment and Embodiment 1 is that the assembled light engine has a micro display chip, and the corresponding attaching part includes a first clamping member. The first clamping member is arranged corresponding to the position where the color combining prism needs to be installed with the micro display chip.

Abstract

The invention discloses optical engine assembly equipment and an assembly method. The equipment comprises a workbench, a mounting frame, a first adjusting mechanism, a first operation table, a second adjusting mechanism and a second operation table. Adjusting the imaging lens through a second adjusting mechanism to enable the imaging lens to correspond to the position of the output surface of the color combination prism; after the first operation table clamps the micro display chip which is dispensed on the periphery and electrified, an image sensor collects an image so as to adjust the first adjusting mechanism to carry out active alignment on the micro display chip and the imaging lens, and then curing and separating are carried out; the imaging lens is far away from the color combination prism provided with the micro display chip, glue dispensing is conducted on the output face of the color combination prism, images are collected through the image sensor so that the second adjusting mechanism can be adjusted to conduct active alignment of the imaging lens and the color combination prism provided with the micro display chip, then solidification and separation are conducted, and assembling of the optical engine is completed. According to the optical engine, high position matching precision among the micro display chip, the color combination prism and the imaging lens in the optical engine can be ensured, and the assembly operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of light engine packaging, and in particular relates to an optical engine assembling device and an assembling method for assembling an optical engine by using the light engine assembling device. Background technique [0002] In recent years, with the advent of microdisplay chip technology, miniaturized and high-resolution projection display has become possible. Large field of view, high imaging quality, small size, and wearable micro-projection light engines are getting more and more attention, especially in today's key development of augmented reality (AR), near-eye display (Near-eye display, NED for short) and optical fields such as wearables. [0003] The miniature projection light engine in the prior art is the most critical component in the projection imaging system; among them, in order to realize the color display, the miniature projection light engine usually adopts a color combination device such a...
