The invention discloses an XR-based immersive three-dimensional modeling and straight-through 3D printing system and method, and the method comprises the steps: S1, collecting user input, and converting the user input into an interaction instruction; s2, generating three-dimensional model data; s3, superposing the three-dimensional model into a real physical environment according to a proportion of 1: 1, and outputting a virtual-real fusion display result; s4, performing printability analysis on the model, marking a problem area, guiding a user to modify and providing an automatic repair suggestion; s5, generating a support structure, and providing visual preview and interactive editing; s6, slicing and path planning are executed, and a printing instruction file meeting the control requirement of the 3D printer is generated; s7, communication connection with the 3D printer is established, and printing state information is fed back; and S8, providing storage and calling support of the three-dimensional model file, parameter configuration and environment map data. According to the invention, seamless integration of immersive XR modeling, MR real-time verification and one-key direct-through 3D printing is realized.

This invention discloses a fully automatic double-sided polishing device for circular stones, comprising: a conveying mechanism for conveying circular stones; a polishing mechanism disposed above the conveying mechanism for polishing the surface of the circular stones; and a flipping mechanism. This invention achieves continuous polishing of the upper and lower surfaces of the circular stone through the automated coordination of the flipping mechanism, the conveying mechanism, and the polishing mechanism. After polishing one side, the circular stone is automatically clamped and flipped 180° by the flipping mechanism, eliminating the need for manual intervention. This completely eliminates the cumbersome step of manually flipping the stone during the traditional "equipment polishing + manual flipping" mode, avoiding production interruptions and significantly improving production efficiency. Simultaneously, the automated flipping process eliminates the need for manual contact with the circular stone surface, effectively preventing scratches and contamination caused by manual flipping, ensuring product quality consistency and stability, and completely eliminating the safety hazard of large, heavy circular stones slipping and falling during manual flipping.

The application provides an organ chip multilayer cell tissue structure, which comprises an upper layer of a multilayer structure, a middle layer of the multilayer structure and a lower layer of the multilayer structure; the middle layer of the multilayer structure is a self-supporting biological hydrogel support without a supporting film, and cells in the middle layer of the multilayer structure are mixed in the biological hydrogel support; the upper layer of the multilayer structure and the lower layer of the multilayer structure respectively culture different cells and directly contact upper and lower surfaces of the biological hydrogel support. The application truly reproduces a sandwich type multilayer structure of "cell-matrix-cell", avoids problems such as incomplete establishment of cell polarity, imperfect barrier function and distorted signal transmission between cells, and the like; the multilayer cell tissue structure cultured by using the biological hydrogel support avoids interlayer peeling between different layers and structure collapse; and the permeability of the middle layer matrix is convenient to adjust.

The embodiment of the application provides a baby carriage, and relates to the technical field of baby carriages. The baby carriage comprises a frame and a seat installed on the frame. The frame is locked in an unfolded state by a locking mechanism. The locking mechanism comprises a locking groove arranged on a push handle and a locking block arranged on a base. The seat bottom is provided with at least one protruding part. When the seat is rotated from the unfolded position to the folding direction relative to the frame, the protruding part contacts and applies a driving force to the locking block, so that the locking block is separated from the locking groove, thereby linkage unlocking of the frame during folding of the seat is realized, and one-step folding operation is achieved. The end of the protruding part is provided with an abutting inclined surface, so that the seat can avoid the locking block when being turned back to unfold from the folded state, and mislocking is prevented. The seat can be installed in a forward direction or a reverse direction, the locking block is driven by different protruding parts, and the generality is high. The application simplifies the operation steps, and improves the convenience and safety.
