Description
Technical Field
[0001] This utility model relates to the field of semiconductor equipment accessories technology, and in particular to a device for quickly removing FOSB filter cartridges. Background Technology
[0002] FOSB refers to Front-Opening Transport Wafer Container, a key device used for wafer storage and transportation. It has the following core characteristics and application scenarios. It contains a filter structure to adsorb waste from the wafer cleaning process. The filter structure will become unusable during use. The conventional filter structure is very complicated and difficult to disassemble and replace. To solve this problem, an auxiliary device is needed to facilitate the disassembly and assembly of the filter. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a quick removal device for FOSB filter elements, which has the characteristics of convenient filter element removal, reduced operation difficulty and low manufacturing cost.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a device for quickly removing FOSB filter elements is provided, including an outer cylinder, a linear bearing, and an inner shaft. The upper end of the outer cylinder is equipped with a linear bearing, and the inner shaft, which can slide up and down, is vertically installed on the inner ring of the linear bearing. The lower end of the outer cylinder is provided with a hook mounting port, and two hooks are symmetrically installed on the hook mounting port. When the lower end of the inner shaft is fully inserted, the lower end of the inner shaft is located between the two hooks and pushes the lower ends of the hooks to move to the left and right sides. The middle of the lower end of the inner shaft is provided with a mating interface, and two snap-fit protrusions are provided on the inner side wall of the mating interface.
[0005] After the filter element structure is inserted into the equipment, there are two snap-fit protrusions inside the equipment that hold the upper end of the filter element structure in place, thus ensuring that the filter element structure is installed in place. At the same time, there are two symmetrical mating ears on the upper end of the filter element structure.
[0006] The outer cylinder serves as the docking body for inserting the equipment, facilitating docking with the device. A linear bearing is installed to stabilize the movement of the inner shaft, which can move vertically along the inner ring of the linear bearing. A hook mounting port is provided at the lower end of the outer cylinder for easy hook installation. The hook is used to push the snap protrusion at the filter element installation position, opening the snap protrusion and facilitating the removal of the filter element structure. At the same time, a mating interface is provided to facilitate docking between the inner shaft and the upper end of the filter element structure, and the snap protrusion can mate with the docking lug.
[0007] When removing the filter element, first insert the outer sleeve into the mounting port of the filter element structure on the equipment. Then insert the inner shaft. When the inner shaft is inserted to the bottom, the lower end of the inner shaft will push the hook, and the lower end of the hook will push outward. The hook will push the snap-fit protrusion, and the snap-fit protrusion will disengage from the filter element structure. At the same time, the interface at the lower end of the inner shaft will fit into the filter element structure. Then rotate the inner shaft so that the snap-fit protrusion of the inner shaft aligns with the mating ear of the filter element structure. Finally, pull up the filter element structure with the inner shaft so that the filter element structure can be detached from the equipment.
[0008] As a supplement to this technical solution, the lower end of the linear bearing is inserted into the inner ring of the outer cylinder, and the upper end of the linear bearing is annular and fixed at the upper end of the outer cylinder. In this technical solution, the structural compactness of the device is improved by setting a linear bearing.
[0009] As a supplement to this technical solution, the upper end of the hook is connected to the hook mounting port via a longitudinal rotating shaft, and a reset coil spring is sleeved on the longitudinal rotating shaft. By setting the reset coil spring, the hook can easily return to its original state.
[0010] As a supplement to this technical solution, the two snap-fit protrusions are arranged clockwise along the inner wall of the interface.
[0011] As a supplement to this technical solution, the snap-fit protrusion is arc-shaped and fits snugly on the inner side wall of the interface, and a stepped protrusion extending towards the center of the interface is provided on the lower side of the snap-fit protrusion.
[0012] As a supplement to this technical solution, a handle is installed at the upper end of the inner shaft, and the handle controls the rotation of the inner shaft.
[0013] Beneficial Effects: This utility model relates to a quick-release device for FOSB filter elements. An outer cylinder serves as the docking body for insertion into the equipment, facilitating docking. A linear bearing stabilizes the movement of the inner shaft, allowing it to move vertically along the inner ring of the bearing. A hook mounting port at the lower end of the outer cylinder facilitates hook installation. This hook allows for easy pushing of the snap-fit protrusion at the filter element mounting position, opening the protrusion and facilitating filter element removal. A mating interface facilitates docking between the inner shaft and the upper part of the filter element structure. The snap-fit protrusion engages with the docking lug. This device offers advantages such as convenient filter element removal, reduced operational difficulty, and low manufacturing cost. Attached Figure Description
