Description

Layer height adjusting type three-dimensional shelf for semiconductor products Technical Field The invention relates to the technical field of semiconductors, in particular to a layer height adjusting type three-dimensional shelf for semiconductor products. Background At present, materials in semiconductor production workshops are mainly stored on various shelves. For a high-level goods shelf, materials can be placed on a tray, and then the materials are taken and placed by using a forklift, for a low goods shelf, small materials can be taken and placed directly by workers, and for large materials, the materials still need to be taken and placed by using the forklift. When the space is limited, the high-level goods shelf can not use a forklift to take and put materials, and under the condition of only relying on manpower, the high-level goods shelf can not be used for storing large materials for precision products such as semiconductors, and if the low goods shelf is used, the utilization rate of the vertical space is not high. Because the heights of the workshop materials are different, the problem that the utilization rate of shelf space is not high exists for storing the materials with partial smaller heights. There are a great deal of three-dimensional goods shelves in the prior art, for example, CN111498337B, a material storage is adjustable novel three-dimensional goods shelves, and the baffle on the three-dimensional goods shelves for the current material storage is all fixed, when meetting great article, it is inconvenient to place to the angle of the pull rod of three-dimensional goods shelves is inconvenient to adjust, and the people of different heights of being inconvenient for pull the problem of three-dimensional goods shelves through the pull rod, proposes the following scheme, and it includes the bottom plate, the equal fixedly connected with curb plate in top both sides of bottom plate, two fixedly connected with decides the baffle between two curb plates, the same roof of top fixedly connected with of two curb plates, the change groove has all been seted up to one side that two curb plates kept away from each other, and the pivot is installed to the change inslot rotation, and the equal fixedly connected with of one end that two pivots kept away from each other links the board. The invention is convenient to adjust the position of the movable partition board, is convenient for storing larger objects, can adjust the angle of the pull rod, and meets the use requirements of people with different heights. However, the requirements of the semiconductor products on the storage conditions are high, and the semiconductor products need to be prevented from touching in the storage process, so that the existing technical scheme cannot meet the storage and taking requirements of the goods of the semiconductor products. Disclosure of Invention The invention aims to solve the problems that the existing three-dimensional shelf cannot meet the storage requirement of semiconductor products, when the space is limited, a forklift cannot be used for taking and placing materials by the high-level shelf, and under the condition of manpower only, the high-level shelf cannot be used for storing large materials for precision products such as semiconductors, and if a low shelf is used, the utilization rate of vertical space is not high, and the like. The invention aims to provide a layer height-adjustable three-dimensional goods shelf for semiconductor products, which comprises a goods shelf main body, wherein a goods taking place position and a goods storage place position are arranged in front of and behind the goods shelf main body, a plurality of layers of height-adjustable goods storage spaces are arranged in the goods storage place position, a tray moving supporting mechanism is arranged on each layer of goods storage space, a sliding tray is arranged on each tray moving supporting mechanism, a goods taking place platform is arranged on the goods taking place, a two-stage telescopic mechanism and a chain wheel transmission mechanism for achieving lifting and grabbing of the tray are arranged on the goods taking place platform, and the goods taking place platform is driven to ascend and descend through the chain wheel transmission mechanism. This three-dimensional goods shelves of layer height regulation formula for semiconductor product utilizes the tray as the transfer, realizes that the semiconductor material gets to put, can guarantee the semiconductor material quality, utilizes sprocket drive mechanism to realize getting the lifting operation when putting the vertical movement of platform and snatching the tray, has guaranteed the stability of tray horizontal migration and vertical lift process. The tray moves back and forth between the storage position and the picking and placing position to achieve picking and placing of materials, the tray moves to the picking and placing platform and then moves to the
