Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically to a crystal cell positioning shelf. Background Technology

[0002] In fields such as semiconductor manufacturing, electronic component production, and precision instrument storage, the safety of storage and transportation of wafer cassettes (silicon wafer storage boxes) is of paramount importance. Wafer cassettes are typically used to house high-value, highly fragile precision components; any accidental drop or impact could damage the internal components, resulting in significant economic losses.

[0003] To prevent crystal boxes from sliding, tilting, or even tipping over, existing crystal box racks are generally not convenient to handle directly using forklifts or other automated transport mechanisms. Especially in unmanned warehouses, the offset of crystal boxes during storage may cause them to fall during automated transfer, resulting in losses. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a crystal box positioning shelf, which is achieved through the following technical solution:

[0005] A crystal box positioning shelf includes multiple uprights and multiple horizontal shelves. The uprights are vertically installed on the ground. The horizontal shelves are installed in pairs on the uprights. Each pair of horizontal shelves is installed at the same horizontal height, and there is a gap between each pair of horizontal shelves. The upper surface of each horizontal shelf is provided with multiple positioning seats. The positioning seats are used to limit the crystal box.

[0006] Optionally or preferably, it includes multiple sets of paired horizontal shelves; different sets of horizontal shelves are installed at different heights of the uprights to form a multi-layer storage structure.

[0007] Optionally or preferably, the number of positioning seats is multiple. When the horizontal shelf supports the crystal box, the multiple positioning seats surround the crystal box, and place the two ends of the crystal box on a pair of horizontal shelves, and place the middle part of the crystal box above the gap between the pair of horizontal shelves.

[0008] Optionally or preferably, the positioning seat is a triangular prism structure; the side of the positioning seat near the crystal box is a sloping structure, so that when the crystal box is misplaced, it can move along the slope under the action of gravity, thereby adjusting the placement position of the crystal box.

[0009] Optionally or preferably, each of the horizontal shelves is provided with multiple positioning seats with different orientations; the positioning seats with different orientations on a pair of horizontal shelves are used to position and restrict the different orientations of the crystal cell.

[0010] Optionally or preferably, each of the horizontal shelves is provided with four positioning seats.

[0011] Optionally or preferably, the column is made of square steel or I-beam steel; the horizontal shelf is installed on the column by welding, screwing or riveting.

[0012] Optionally or preferably, the column is also equipped with a photoelectric sensor; the sensing direction of the photoelectric sensor is toward the gap between each pair of horizontal shelves, and is used to identify whether there are crystal boxes stored on the shelf.

[0013] Optionally or preferably, both the horizontal shelf and the positioning seat are made of a smooth metal material.

[0014] Based on the above technical solution, the following technical effects can be achieved:

[0015] This utility model provides a crystal box positioning shelf with a simple structure that can automatically adjust the placement of crystal boxes, making it suitable for unmanned warehouses. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0021] In a preferred embodiment:

[0022] like Figure 1 As shown:

[0023] This embodiment provides a crystal box positioning shelf, including multiple uprights 1 and multiple horizontal shelves 2. The uprights 1 are vertically installed on the ground. The horizontal shelves 2 are installed in pairs on the uprights 1. Each pair of horizontal shelves 2 is installed at the same horizontal height, and there is a gap between each pair of horizontal shelves 2. The upper surface of the horizontal shelves 2 is provided with multiple positioning seats 3. The positioning seats 3 are used to limit the crystal boxes.

[0024] Furthermore, in this embodiment, multiple sets of paired horizontal shelves 2 are included; different sets of horizontal shelves 2 are installed at different heights of the column 1 to form a multi-layer storage structure.

[0025] Furthermore, in this embodiment, there are multiple positioning seats 3. When the horizontal shelf 2 supports the crystal box, the multiple positioning seats 3 surround the crystal box, and place the two ends of the crystal box on a pair of horizontal shelves 2, and place the middle part of the crystal box above the gap between the pair of horizontal shelves 2.

[0026] Furthermore, in this embodiment, the positioning seat 3 is a triangular prism structure; the side of the positioning seat 3 near the crystal box is a sloping structure, so that when the crystal box is misplaced, it can move along the slope under the action of gravity, thereby adjusting the placement position of the crystal box.

[0027] Furthermore, in this embodiment, each of the horizontal shelves 2 is provided with multiple positioning seats 3 with different orientations; a pair of positioning seats 3 with different orientations on the horizontal shelves 2 are used to position and restrict the different orientations of the crystal box, thereby enabling the crystal box to be accurately positioned and stored in the unmanned warehouse.

[0028] Furthermore, in this embodiment, each of the horizontal shelves 2 is provided with four positioning seats 3.

[0029] Furthermore, in this embodiment, the column 1 is a metal square steel or I-beam; the horizontal shelf 2 is installed on the column 1 by welding, screwing or riveting.

[0030] Furthermore, in this embodiment, the column 1 is also provided with a photoelectric sensor 4; the sensing direction of the photoelectric sensor 4 is toward the gap between each pair of horizontal shelves 2, and is used to identify whether there are crystal boxes stored on this shelf.

[0031] Furthermore, in this embodiment, both the horizontal shelf 2 and the positioning seat 3 are made of smooth metal material.

[0032] The crystal cell positioning shelf provided in this embodiment has the following advantages:

[0033] (1) This embodiment can realize multi-layer storage of chips in a limited space, with high space utilization and is suitable for high-density unmanned warehouse scenarios;

[0034] (2) The triangular prism slope structure of the positioning seat 3 in this embodiment utilizes the gravity self-correction principle. When the crystal box is placed off-center, the crystal box automatically slides into the preset position along the slope without manual adjustment, greatly reducing the complexity of operation and improving the automation level of the unmanned warehouse.

[0035] (3) The positioning seats 3 on each horizontal shelf 2 with different orientations form a three-dimensional enclosure and limiting area, which constrains the displacement of the crystal box from multiple directions such as front and back, left and right, to ensure that the crystal box maintains a stable posture under the vibration of handling or external force interference.

[0036] (4) The photoelectric sensor 4 can monitor the existence status of the crystal cell in the gap of each pair of horizontal shelves 2 in real time, and feed the data back to the warehouse management system to realize dynamic inventory tracking and shortage alarm, and avoid missing or mis-taking.

[0037] (5) The column 1 is made of metal square steel or I-shaped steel, and the horizontal shelf 2 and positioning seat 3 are made of smooth metal material. They have both high strength and low friction characteristics, and there is no risk of wear and jamming during long-term use. They are suitable for high-cleanliness workshop environments.

[0038] (6) The horizontal shelf 2 is fixed to the column 1 by welding, screwing or riveting, which supports quick disassembly and height adjustment to meet the storage needs of different sized crystal boxes; the positioning seat 3 can be replaced independently, and the maintenance cost is low.

[0039] The working principle and process of the unmanned warehouse in this embodiment are as follows:

[0040] The crystal box is placed on a pair of horizontal shelves 2 by automated equipment (such as an automatic trolley). Its two ends are supported by the surfaces of the two horizontal shelves 2 respectively, and the middle is suspended above the gap to distribute the weight.

[0041] If the initial position of the crystal box deviates from the preset area, its bottom surface will contact the slope of the positioning seat 3 and slide along the slope under the action of gravity until it is accurately centered.

[0042] The positioning seat 3 on the horizontal shelf 2 surrounds the crystal box, forming a rectangular limiting area. Each side of the crystal box is blocked by the positioning seat 3, effectively displacing the crystal box.

[0043] The direction finding of photoelectric sensor 4 passes through the gap of horizontal shelf 2. When the crystal box is placed in place, the beam is blocked and photoelectric sensor 4 outputs an "occupied" signal. After the crystal box is removed, the beam is restored and triggers the "idle" state update.

[0044] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
