The invention relates to the design and manufacturing method of a micro-mechanical acceleration sensor based on the heat convection principle. The thermal convection micro-mechanical acceleration sensor involved in the present invention does not open a hole on the silicon chip to form a cavity structure, but forms a closed cavity by bonding the glass cover plate and the silicon chip through BCB bonding glue, and in the first A layer of polyimide film is made on the substrate to prevent heat loss, to ensure that the hot air mass plays a better role and reduce power consumption. In addition, the polyimide film can also prevent the leakage of platinum electrodes. This design makes the process easier. The method is simple and the fabricated sensor has a more stable structure, high reliability and better performance.

The invention relates to a glass automatic sorting processing facility and a glass sorting processing method. The glass automatic sorting processing facility comprises a base plate, water removal devices, a screening device and a cleaning device. The two water removal devices are arranged and installed on the upper end face of the base plate in a left-and-right symmetry mode. The screening deviceis installed on the upper end face of the middle of the base plate. The cleaning device is installed on the upper end face of the right side of the base plate. The glass automatic sorting processing facility can solve the problems that by the adoption of an existing glass sorting facility, sorting of glass is not accurate enough, the broken glass cannot be well fixed in the sorting process, the glass which is sorted is not timely subjected to water removal treatment, other things on the glass are not cleaned away before the glass is sorted, and the interlayer phenomenon happens in the sorted glass. The functions that the glass is automatically sorted and recovered, and the sorted glass is subjected to water removal can be fulfilled.

The invention discloses a steel pipe perforating machine which comprises a base. Supporting frames are fixedly mounted at the two ends of the upper surface of the base. A moving lead screw is mounted on the supporting frames in a sleeved manner. A scrap collection mechanism is mounted on the moving lead screw in a sleeving manner. The bottom end of the scrap collection mechanism is fixedly connected with an electric telescopic rod. The end, far away from the scrap collection mechanism, of the electric telescopic rod is fixedly connected with a perforating motor. A drill bit is fixedly mounted on an output shaft of the perforating motor. A scrap guide hole communicating with the scrap collection mechanism through a hose is formed in the top of the drill bit. A sealing piece is arranged on the outer portion of the scrap guide hole, wherein the drill bit is sleeved with the sealing piece. Scrap collection holes communicating with the scrap guide hole are formed in the bottom end of the drill bit at equal distance. One end of the moving lead screw penetrates and extends out of one supporting frame to be fixedly connected with the axis of a driven disc. According to the steel pipe perforating machine, the scrap collection holes are formed in the drill bit and cooperate with the scrap collection mechanism, negative pressure is generated through a draught fan, and therefore scraps generated by machining can be collected, and the situation that the scraps are accumulated, and consequently next machining is influenced is avoided.
