The utility model relates to the field of early warning device, solve the problem that the existing anti -collision early warning device is easy to fall off when the collision of offshore facilities, provide a kind of anti -collision early warning device, including installation part and damping mechanism, installation part is used to carry detection device, and installation part is the box body of one end opening, damping mechanism includes: protective plate, groove, guide rod, guide block, elastic part and rotating rod, protective plate and the open end of installation part are slidably connected, and sliding direction is along the depth direction of installation part;Groove is connected with the side close to installation part of protective plate;Guide rod is connected with the inner wall of groove;Guide block is sleeved in guide rod, and is slidably connected with guide rod;Elastic part is arranged between guide block and the end wall of groove;One end of rotating rod is rotatably connected with slider. The utility model increases the anti -collision structure distinguishing from air cushion on the protective plate, so that protective plate not only has certain activity, but also can increase the anti -collision performance of early warning device.

The application provides a quartz boat taking device, and relates to the field of semiconductor manufacturing. The quartz boat taking device comprises a taking device body, a connecting piece and a handheld piece. The connecting piece is connected with the taking device body and the handheld piece respectively. The taking device body is used for cooperating with a quartz boat. The handheld piece is used for being held by an operator to take and place the quartz boat through the taking device body. The quartz boat taking device has the characteristics of being convenient to hold, can facilitate the operator to take and place the quartz boat, can effectively reduce or avoid the problem of collision and damage of the quartz boat and fragments caused by improper operation when the operator places and takes the quartz boat, and can also reduce or avoid the problems of cost waste caused by damage of the quartz boat and contamination of the furnace tube caused by the broken chips, thereby helping to improve the quality of the chips and improve the yield of the chips.

This utility model provides a hinge and a refrigerator including the same. The hinge includes: a first fixed base; a second fixed base; a transmission assembly; and a buffer assembly, which is mounted on the first fixed base or the second connecting member and extends toward the fifth connecting member. A buffer mating part is provided on the side of the fifth connecting member facing the buffer assembly. The buffer assembly is configured to switch from a non-active state to an active state when the buffer mating part abuts against the buffer end face of the buffer assembly during the closing process of the door. The fifth connecting member is the rod used to cooperate with the buffer assembly to achieve the buffering effect. During opening and closing, the fifth connecting member bears a smaller weight of the door, which helps to ensure the overall strength of the hinge. Mounting the buffer assembly on the first fixed base or the second connecting member increases the buffer stroke of the buffer assembly, enabling it to maintain a better buffering effect even when the door speed changes abruptly, thereby reducing or preventing damage to the refrigerator door and cabinet.

The application provides a method and system for segmenting FMM plates. The method comprises identifying whether the segmentation strip on the FMM plate after the first etching and before the etching back protection film is removed is an etching residual segmentation strip, determining the etching parameters corresponding to the secondary etching according to the gray scale image of the etching residual segmentation strip; based on the coordinate range of each etching residual segmentation strip and the etching parameters corresponding thereto, combining the contour image of the etching front surface non-etching area (product unit area) of the FMM plate to control the precise spraying mechanism and etching nozzle to perform secondary etching on all etching residual segmentation strips. The technical solution provided by the application accurately identifies the etching residual segmentation strips on the FMM with the aid of image recognition technology, accurately controls the spraying mechanism and etching nozzle to perform secondary etching on the etching residual segmentation strips, ensures that the product unit will not be damaged when the protection film is removed, and improves the yield of FMM products.

The utility model relates to the technical field of stackers, and discloses a single-stand-column stacker which comprises stand columns, guide wheel assemblies, a transmission chain, linear guide rails, a connecting plate, a quick-release mounting assembly, a deck plate, a top box and a safety belt. The stand column is provided with an installation area, the guide wheel assembly is used for changing the transmission direction of the transmission chain, and the two ends of the transmission chain are fixed to the connecting plates and wound around the guide wheel assembly. The connecting plate is slidably arranged on the linear guide rail and is used for reciprocating along the length direction of the linear guide rail; the quick-release mounting assembly is arranged on the connecting plate, and the deck plate is arranged on the quick-release mounting assembly; the two ends of the safety belt are connected with the mounting base and the connecting plate respectively. A linear guide rail structure is adopted, linearity can be kept in the movement process, movement stability is ensured, and safety is improved. The top box is installed in the installation area of the stand column and does not protrude out of the end of the stand column, damage to the safety belt in the transportation process can be reduced or avoided, and cost is reduced.
