Description

Technical Field

[0001] This utility model relates to the field of photovoltaic silicon rod slicing technology, specifically a silicon rod crystal holder device that facilitates material feeding and reduces the impact of jumper wires. Background Technology

[0002] In recent years, the photovoltaic industry has developed rapidly, with silicon wafer preparation playing an increasingly important role in the entire industrial chain. However, during the process of cutting silicon rods into wafers, wire breakage often occurs, especially jumper wire breakage. Human factors are the most obvious and easiest to control. Currently, the crystal holders used to bond silicon rods have two through holes on each side to hold metal rods as support devices for placing them on the unloading trolley, in order to facilitate material unloading. Metal debris is very likely to remain in these holes, causing jumper wire problems during the slicing process. Therefore, how to reduce the occurrence of jumper wire breakage, thereby reducing diamond wire loss and saving raw materials, has become a focus of widespread attention in the technological research and development and actual production of the wafer slicing field.

[0003] The current method for unloading silicon ingots and wafer trays involves using a loading and unloading gripper to remove the wafer trays from the slicing machine. Workers then insert two metal rods into holes on both sides of the wafer tray, and the gripper places it on an unloading trolley, using the two metal rods as support points. Currently, these metal rods are used as support devices; they are inserted during unloading and removed before debonding, which is time-consuming. Furthermore, large metal fragments and dirt can easily fall into the wire mesh through the through holes on both sides of the wafer tray during slicing, causing wire breakage and affecting yield and reducing actual output. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a silicon rod holder device that facilitates material feeding and reduces the impact of jumpers, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a silicon rod crystal holder device that facilitates material feeding and reduces the impact of jumpers, comprising a crystal holder and a support rod structure device. The support rod structure device is located inside both sides of the crystal holder. The support rod structure device includes a main support rod, a sleeve is sleeved on the surface of the main support rod, and key blocks are fixedly connected to the bottom of both sides of the surface of the main support rod. A handle is fixedly connected to the top of the main support rod.

[0006] Preferably, the number of the support rod structure devices is four, and they are equally distributed on both sides of the crystal holder.

[0007] Preferably, the crystal holder has holes on both sides that are adapted to the support rod structure, and the sleeve is fixedly connected to the inner wall of the hole.

[0008] Preferably, the inner wall of the sleeve is adapted to the surface of the key block, and the inner wall of the sleeve is provided with a keyway adapted to the key block.

[0009] Beneficial effects

[0010] This invention provides a silicon rod crystal holder device that facilitates material unloading and reduces the impact of jumper wires. Compared with the prior art, it has the following advantages: This silicon rod crystal holder device, which facilitates material unloading and reduces the impact of jumper wires, uses a support rod structure located inside both sides of the crystal holder. The support rod structure includes a main support rod, with a sleeve fitted on the surface of the main support rod. Key blocks are fixedly connected to the bottom of both sides of the main support rod, and a handle is fixedly connected to the top of the main support rod. The original through hole for placing the support rod is replaced by a support rod device, which reduces the time cost of manual handling of the support rod and solves the problem of dirt and debris easily left in the through hole during handling and cutting / debonding, affecting the cutting yield and economic benefits. The unloading efficiency is higher, avoiding the time consumed by transporting the metal rod back and forth for unloading and debonding, and reducing the jumper wire breakage rate caused by debris in the crystal holder holes from 4.5% to 3%.
