The imaging assembly 20 is movably mounted on the crossbeam 11 via a first drive member 21. Specifically, the first drive member 21 includes a motor, a linear guide rail, and a slider. The imaging assembly 20 is fixed to the slider. The imaging assembly 20 includes a DMD (Digital Micromirror Device) module, a collimating lens group, a reflector group, and an imaging lens group. The collimating lens group is connected to the laser assembly. The laser assembly generates a laser beam, which is collimated by the collimating lens group to become parallel light. The collimated laser beam is irradiated onto the DMD module. The micro-mirror array on the DMD module performs high-speed flipping according to the input image signal, thereby modulating the laser beam to form an image beam. Furthermore, the modulated image beam is reflected by the reflector group and transmitted to the imaging lens group. The imaging lens group focuses and amplifies the image beam, ultimately forming a clear image on the projection surface of the product. In the above process, the DMD module is responsible for high-speed modulation of the laser beam to achieve image display; the collimating lens group, reflecting lens group and imaging lens group are responsible for transmitting and processing the laser beam to ensure the clarity and brightness of the image.
