This invention discloses a silicon nitride grinding device, relating to the technical field of silicon nitride grinding devices. The device includes a support frame and a collection box. A conical cylinder is fixedly mounted on the upper surface of the support frame, and the collection box is disposed on the lower surface of the support frame. A feed trough is fixedly mounted on the upper surface of the conical cylinder, and a water storage tank is fixedly mounted on the circumferential surface of the conical cylinder. A water spray head is provided on the inner wall of the conical cylinder. A rotating shaft is rotatably mounted on the upper surface of the inner wall of the conical cylinder, and a grinding head is fixedly mounted on the lower surface of the rotating shaft. A grinding disc is fixedly mounted on the inner wall of the conical cylinder. A material unblocking device is also provided inside the conical cylinder. When the feed trough is blocked, it affects the grinding efficiency, potentially causing a decrease in output or production stoppage. Blockage causes material to accumulate in the feed trough, increasing the pressure and stress on the material. If this blockage persists for a long time, it may damage the feed trough.

This invention discloses an indoor mid-to-long-range camera heart rate detection method and system with resistance to environmental interference. The host computer acquires one video stream from each camera to determine the video frame sequence of the current optimal viewing angle. Face detection, tracking, and ROI localization are performed on the video frame sequence to obtain the face ROI region for each video frame. Rigid motion noise filtering is applied to the video frame sequence to obtain an aligned frame sequence and a reference frame sequence. The face ROI region of each aligned frame is determined based on the face ROI region of the reference frame. The ROI signal is determined based on the face ROI region of the aligned frame, and non-rigid noise is filtered out to obtain a pulse wave signal. The heart rate value corresponding to the current sliding window is determined based on the pulse wave signal, and a corresponding quality score is determined. This, combined with a preset correspondence between distance and available focal length, allows for adaptive adjustment of the camera focal length. This invention exhibits high robustness, accuracy, and stability.

This invention provides a method for regulating the eutectic reaction mechanism of DBC (Dielectric-Ceramic Composite) substrates, belonging to the field of DBC substrate fabrication technology in power electronic packaging. Addressing the problems of interfacial brittleness, intermetallic compound aggregation, low bonding strength, and poor thermal cycling reliability caused by thermal expansion coefficient mismatch and stress concentration in traditional DBC processes, this invention proposes a three-pronged approach to actively regulate the stress field: interface microstructure guidance, gradient thermal field control, and dynamic mechanical constraint. Through ten steps including substrate pretreatment, microstructure patterning, gradient thermal field construction, dynamic pressure application, in-situ stress monitoring, and segmented cooling, precise spatiotemporal control of the interface stress field is achieved, promoting the formation of a dense and uniform interface layer. Experiments show that the DBC substrate prepared by this invention exhibits over 30% improved interfacial bonding strength and over 2 times improved thermal cycling life. It also demonstrates strong process compatibility and excellent controllability, making it suitable for demanding applications such as high-end power electronic devices.

This utility model discloses an electrode coating processing and drying structure. A clamping mechanism holds the electrode sheet, which, with the cooperation of a trolley and a slide rail, transports the electrode sheet to the drying unit. The electrode sheet enters the heating chamber through a first clearance notch. A hot air blower stably inputs hot air into the heating chamber through a hot air inlet to complete preheating or drying. The entire drying process requires no manual operation, conforming to the trend of automation in manufacturing. This not only reduces the labor intensity of workers but also lowers the risk of workers being burned by heating equipment or electrode sheets. Furthermore, the automatically controlled trolley moves along the slide rail, effectively ensuring consistent heating time. During drying and heating, the electrode sheet and the heating chamber remain relatively stationary, ensuring uniform heating of each electrode sheet and resulting in more consistent coating quality. This effectively solves the technical problem of high labor intensity associated with manual preheating and drying in current electrode coating processing, achieving improved coating processing quality and safety.

This invention relates to the field of data processing technology for production traceability and quality management, and discloses a method for sampling, sealing, and tracing continuous production lines. It addresses the problems of traditional methods, such as the lack of a freezeable and auditable management mechanism, and the inability to bind sample IDs with production line events, batch boundaries, and workstation equipment status to form adjudicable evidence. The method first generates a traceability session, freezes field mapping, batch boundaries, time alignment, and repairs adjudication rule versions. Then, it integrates manufacturing execution, equipment control, quality inspection, warehousing and transfer, and sealing cabinet records, unifying them into a single event, noting time, quality, and completeness. It aligns tolerance-related event chains, segments batches and transition segments, and adds missing or conflicting events to the accounting system. Sampling triggers the generation of sample identifiers, label verification, seal registration, cabinet binding, and extraction of evidence window indexes. Disputes trigger the verification of evidence packages, adjudicate batch and segment boundaries, and output verifiable conclusions.

The application provides a preparation method of a Gaussian diffusion sheet and belongs to the field of optical diffusion sheet manufacturing. The base is immersed in an etching solution for wet etching, and then the diffusion angle is screened to obtain a Gaussian diffusion sheet mold. The type of the base is limited to ensure that the prepared Gaussian diffusion sheet mold can be reused, thereby reducing the production cost. The diffusion angle deviation is controlled during the screening to improve the accuracy of the diffusion angle of the Gaussian diffusion sheet mold. Then, the Gaussian diffusion sheet base material is molded by using the Gaussian diffusion sheet mold as a template. The fixed Gaussian diffusion sheet mold can accurately copy the micro-nano convex or concave structure of the Gaussian diffusion sheet mold to the Gaussian diffusion sheet base material, thereby ensuring that the consistency of the Gaussian diffusion sheets obtained in the same batch or different batches is high.
