Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning disc for cleaning zone-melted germanium ingots. Background Technology

[0002] Currently, the production of zone-refined germanium ingots mainly follows the standard GB / T 11071-2018 "Zone-Refined Germanium Ingots". Section 3.4 of GB / T 11071-2018 specifies the surface quality requirements for zone-refined germanium ingots as follows: "The surface of zone-refined germanium ingots should have a silvery-gray luster, free from oxide films, cracks, pores, and slag." However, during the production process, impurities inevitably adhere to the surface, affecting its appearance. To meet the standard's quality requirements, these impurities are typically removed using acids and alkalis, followed by rinsing with pure water and drying to remove surface moisture. Currently, the acid and alkali cleaning and rinsing processes are primarily done manually. This approach is problematic because it compromises inherent safety, posing a risk of acid and alkali corrosion to cleaning workers. Furthermore, incomplete cleaning may occur, affecting the appearance of the zone-refined germanium ingots and consequently impacting the overall product quality. When using equipment for cleaning, a tray is needed to support the molten germanium ingots. This tray needs to be easy to stack the molten germanium ingots without affecting the normal cleaning process, and it also needs to be easy to clamp. There is no such tray in the existing technology. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a cleaning tray for cleaning zone-melted germanium ingots, which is easy to assemble and recyclable.

[0004] This application discloses a cleaning tray for cleaning zone-melted germanium ingots, including a plate and connecting columns that are connected and supported on the plate. The plate is square, with wavy protrusions on one side of the plate. Multiple through holes are arranged in an array at the troughs of the wavy protrusions. Side grooves are formed on both sides of the plate, and connecting shaft holes are formed at the four corners of the plate. Connecting columns are inserted into the connecting shaft holes.

[0005] Optionally, wavy protrusions are arranged vertically and horizontally on the surface of the plate to form point-like support protrusions, and through holes are set at the confluence of the troughs.

[0006] Optionally, the side grooves are constructed on all four sides of the plate.

[0007] Optionally, staggered, wave-shaped protrusions are symmetrically arranged on the upper and lower surfaces of the plate.

[0008] Optionally, the connecting shaft holes are symmetrically arranged on both surfaces of the plate and are stepped through holes.

[0009] The technical solution provided in this application may include the following beneficial effects:

[0010] This device uses ultrasonic vibration cleaning in the cleaning tank to ensure thorough contact between the cleaning acid / alkali, the rinsing pure water, and the molten germanium ingot being cleaned. This ensures a complete cleaning process, guaranteeing that the surface quality of the molten germanium ingot meets the required standards and ensuring product quality. The cleaning disc uses W-shaped or wavy raised supports to significantly reduce the contact area between the cleaning disc and the molten germanium ingot, preventing missed cleaning areas. Through holes are provided in the grooves of the W-shaped disc or wavy raised supports to allow the acid / alkali and rinsing pure water to fully contact the molten germanium ingot being cleaned, while also increasing the flowability of the acid / alkali and rinsing pure water for optimal cleaning results.

[0011] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0021] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] To address the aforementioned problems, this application provides a cleaning tray for cleaning zone-melted germanium ingots. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 The cleaning tray shown includes a plate 1 and connecting posts 5 that are connected to the plate and provide support. In this device, the plate 1 is a square plate with wavy protrusions 2 on one surface. Multiple through holes 3 are arranged in an array at the troughs of the wavy protrusions 2. Side grooves 6 are formed on both sides of the plate 1, and connecting shaft holes 4 are formed at the four corners of the plate 1. Connecting posts 5 are inserted into the connecting shaft holes 4.

[0025] In operation, the cleaning tray is placed in the storage mechanism in front of the cleaning tank. When the zone-melted germanium ingots, after resistivity testing and cutting, are transported to the cleaning tank, a robotic arm automatically places them onto the cleaning tray. Once the tray is full of a set number of ingots, a signal is transmitted to the robotic arm in the cleaning section. The robotic arm picks up the tray with the ingots and, according to a preheating tank, acid-alkali cleaning tank, and pure water rinsing tank, completes the acid-alkali cleaning and pure water rinsing of the ingots. They then automatically transfer to the next stage. By using the cleaning tray to support the zone-melted germanium ingots, batch cleaning is achieved, improving cleaning efficiency.

[0026] Thus, this device uses wave-shaped protrusions 2 to hold the molten germanium ingot in place, minimizing contact and reducing cleaning difficulty. Simultaneously, multiple through holes 3 on the plate 1 allow the cleaning solution to overflow from the bottom, cleaning the bottom of the ingot. Side grooves 6 facilitate gripping by a robotic arm. It is important to note that this application requires the use of corrosion-resistant materials for fabrication. Furthermore, this device employs ultrasonic cleaning in the cleaning tank, ensuring thorough contact between the cleaning acid / alkali and rinsing pure water and the molten germanium ingot being cleaned. This ensures complete cleaning, guarantees the surface quality of the ingot meets standard requirements, and safeguards product quality. The cleaning disc uses W-shaped or wavy convex supports to greatly reduce the contact area between the cleaning disc and the molten germanium ingot, so as to avoid cleaning blind spots. Through holes are set in the grooves of the W-shaped disc or wavy convex supports to allow the acid, alkali and rinsing pure water to fully contact the molten germanium ingot being cleaned, while increasing the fluidity of the acid, alkali and rinsing pure water to achieve the best cleaning effect.

[0027] In one embodiment, such as Figure 2 In order to minimize contact with the zone-melted germanium ingot, wavy protrusions 2 are arranged vertically and horizontally on the surface of the plate 1 to form point-like support protrusions 7, and through holes 3 are set at the intersection of the troughs. In this way, the contact with the zone-melted germanium ingot becomes point-like, and the contact area is reduced.

[0028] In one embodiment, the side slots 6 are constructed on the four sides of the plate 1 for easy clamping.

[0029] In one embodiment, such as Figure 3 and Figure 4 As shown, staggered, wave-shaped protrusions 2 are symmetrically arranged on the upper and lower surfaces of the plate 1. Connecting shaft holes 4 are symmetrically arranged on both surfaces of the plate 1 and are stepped through holes. This facilitates the use of the entire cleaning tray while also ensuring stable connection and support for the connecting shaft holes 4.

[0030] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
