Description

Technical Field

[0001] The utility model relates to the field of monocrystalline silicon wafer manufacturing, in particular to a device for collecting texturing additives. Background Art

[0002] Currently, monocrystalline silicon wafers are basically cut by diamond wires. Without the assistance of texturing additives, an ideal fuzzing effect cannot be achieved. This requires each texturing machine to be equipped with an additive replenishment barrel to transport additives during wafer texturing. The additive contains a surfactant with special functions. Its addition can improve the wettability between the texturing solution and the silicon wafer surface, and the texturing additive has a buffering effect on the transport process of OH- ions from the etching solution to the reaction interface in the etching solution. When a large number of monocrystalline silicon pyramid surfaces are etched, the NaOH content in the solution has a wide process range, which is beneficial to improving the stability of product process quality.

[0003] However, there is a problem with the existing additive replenishment barrel: if there is a large amount of additive in the barrel that cannot be consumed, and when it is urgent to switch to another type of additive, it needs to be directly discharged into the sewage pipeline. The additive is expensive, which will cause great waste. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a device for collecting texturing additives.

[0005] The device for collecting texturing additives provided by the utility model adopts the following technical scheme:

[0006] A device for collecting texturing additives includes a texturing machine, an additive replenishment barrel, and a collection barrel. The additive replenishment barrel contains texturing additives. An external pipeline is provided on the additive replenishment barrel. The external pipeline is connected to the collection barrel, and a solenoid valve is provided on the external pipeline.

[0007] Optionally, a stirring barrel is further provided between the additive replenishment barrel and the texturing machine. A feeding pump is provided on the stirring barrel. The feeding pump pumps the additives in the additive replenishment barrel into the stirring barrel, and the stirring barrel is connected to the texturing machine through a pipeline.

[0008] Optionally, the external pipeline is provided at the bottom of the additive replenishment barrel.

[0009] Optionally, a feeding port is provided at the top of the additive replenishment barrel.

[0010] Optionally, a feeding cover is provided on the feeding port.

[0011] In summary, the utility model includes at least one of the following beneficial technical effects:

[0012] 1. Add a solenoid valve and an external pipeline to the existing additive replenishment barrel, and discharge the additive into the collection barrel through the added pipeline for use by other machines, which can effectively reduce additive waste;

[0013] 2. Set up a stirring barrel between the additive replenishment barrel and the texturing machine. Before transporting the additive, it can be stirred in advance, so that the solid particles or liquid components in the additive can be fully mixed, avoiding uneven distribution or precipitation.
