Description

Technical Field

[0001] This utility model relates to the field of pickling basket technology, and in particular to a novel silicon core pickling basket. Background Technology

[0002] With the development of modern industry, especially in the semiconductor industry, the cleaning process of silicon chips plays a crucial role in production. During the manufacturing process, silicon chips accumulate various stains, oxide layers, and impurities. These stains and impurities need to be removed through chemical cleaning methods such as acid pickling to ensure the quality and performance of the silicon chips. Traditional acid pickling methods often have many problems, such as uneven cleaning results, silicon chip damage, and complex cleaning processes, which affect production efficiency and the yield rate of silicon chips.

[0003] Existing silicon core cleaning devices mostly employ simple soaking or brushing methods. However, these methods cannot effectively guarantee the cleaning effect of each silicon core, nor can they guarantee that the silicon cores will not be damaged due to excessive friction or improper operation during the cleaning process. In addition, the structural design of some existing devices is relatively complex, making equipment maintenance difficult. Furthermore, due to the lack of suitable cleaning media or cleaning methods, the acidic solutions used during the cleaning process may be wasted or contaminated.

[0004] Therefore, we propose a novel silicon core acid washing basket. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a novel silicon core acid washing basket.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel silicon core pickling basket, comprising a pickling basket, a base provided at the bottom of the pickling basket, a top plate that can be flipped up mounted on the top surface of the pickling basket via hinges, mounting plates for easy installation of the pickling basket vertically mounted on both sides of one end of the top surface of the pickling basket, and multiple sets of first cylindrical tubes horizontally fixedly connected to the top of the inner two side surfaces of the pickling basket, one end of each set of first cylindrical tubes horizontally passing through the outer surface of the pickling basket and horizontally located at the outer end of the outer surface of the pickling basket, and a horizontally movable end for entering the pickling basket at the close-to-each end of every two sets of corresponding first cylindrical tubes. The cleaning rollers rotate to clean the silicon core. Each set of cleaning rollers has a limiting plate vertically fixed at both ends to facilitate the limiting of the cleaning rollers. A drive motor that drives the cleaning rollers to rotate is horizontally installed at the outer end of each set of limiting plates. The drive motor is electrically connected to the control panel. Multiple sets of second cylindrical cylinders are horizontally fixedly connected to the inner two sides of the pickling basket below each set of first cylindrical cylinders. A cleaning roller for cleaning the silicon core is horizontally movable between every two sets of second cylindrical cylinders. Water channels arranged in a rectangular pattern are horizontally opened on the four outer sides of the first track to facilitate water inlet. A filter screen is horizontally fixedly connected inside each set of water channels.

[0007] Preferably, each set of mounting plates has horizontally opened mounting holes on its outer surface, the pickling basket has a hollow rectangle inside, and an anti-collision plate is horizontally fixedly connected to the outer surface of the pickling basket to prevent damage caused by collision.

[0008] Preferably, the first cylindrical tubes in each group are horizontally parallel, the two sides of the first cylindrical tubes in each group are open circular grooves, the two ends of the cleaning rollers in each group are located inside the corresponding first cylindrical tube and are movably engaged, and the two ends of the cleaning rollers in each group pass horizontally through the inside of the corresponding first cylindrical tube and are located horizontally at the outer end of the outer surface of the first cylindrical tube.

[0009] Preferably, each set of limiting discs is a vertical disc shape, and a second track is horizontally installed at one end of the outer surface of multiple sets of horizontally corresponding cleaning rollers, which drives the multiple sets of cleaning rollers located at the top to rotate simultaneously. The two ends of the inner surface of the second track are horizontally movably wrapped around the outer surface of the corresponding cleaning roller.

[0010] Preferably, each pair of corresponding second cylindrical tubes are horizontally aligned and one end of each pair of second cylindrical tubes is an open circular groove. Each set of vertically aligned cleaning rollers has a first track that drives the cleaning roller to rotate at one end of its outer surface. The two ends of the inner surface of the first track are movably wrapped around the outer surface of the corresponding cleaning roller.

[0011] This invention provides a novel silicon core acid washing basket. It has the following beneficial effects:

[0012] This novel silicon core pickling basket is used by first mounting the basket onto a lifting assembly using a mounting plate and mounting holes. The top plate is then flipped using hinges, allowing the silicon core to be cleaned to be placed inside the basket between two sets of cleaning rollers. The basket is then lowered into the pickling tank using a lifting device. Pickling solution from the tank flows into the basket through each set of water channels. The drive motor is activated via the control panel, rotating the top cleaning roller. This, in turn, rotates the top cleaning rollers via a second track. The rotation of the top cleaning roller, in conjunction with the first track, causes all the cleaning rollers inside the basket to rotate synchronously. This rotation of the cleaning rollers performs acidic cleaning on the silicon core surface, thus completing the cleaning process. This device is simple and highly practical.

Each group of first cylindrical cylinders 6 is horizontally parallel, with one end of each first cylindrical cylinder 6 horizontally passing through the outer surface of the pickling basket 1 and located horizontally at the outer end of the outer surface of the pickling basket 1. The two sides of each group of first cylindrical cylinders 6 are open circular grooves. A cleaning roller 7, capable of rotating to clean the silicon core, is horizontally and movably mounted at the end of each pair of corresponding first cylindrical cylinders 6 that are close to each other. Both ends of each cleaning roller 7 are movably engaged inside the corresponding first cylindrical cylinder 6, and both ends of each cleaning roller 7 horizontally pass through the inside of the corresponding first cylindrical cylinder 6 and are located horizontally at the outer end of the outer surface of the first cylindrical cylinder 6. Both ends of each cleaning roller 7 are vertically fixedly connected to a [missing information - likely a device or device]. The limiting discs 8 that limit the cleaning rollers 7 are vertically shaped discs. A drive motor 9, which rotates the cleaning rollers 7, is horizontally mounted on the outer end of each limiting disc 8. The drive motor 9 is electrically connected to the control panel. Multiple sets of horizontally corresponding cleaning rollers 7 have a second track 13 horizontally mounted on one end of their outer surface, driving the top sets of cleaning rollers 7 to rotate simultaneously. The inner surfaces of the second track 13 are horizontally and movably wound around the outer surfaces of the corresponding cleaning rollers 7.

Each pair of corresponding second cylindrical cylinders 10 are horizontally aligned, and the ends of each pair of second cylindrical cylinders 10 that are close to each other are open circular grooves. A cleaning roller 7 for cleaning silicon cores is horizontally and movably arranged between each pair of second cylindrical cylinders 10. A first track 11 that drives the cleaning roller 7 to rotate is vertically arranged at one end of the outer surface of each pair of vertically corresponding cleaning rollers 7.
