Description

Technical Field

[0001] The utility model relates to the technical field of quartz rod processing, in particular to a diamond dresser for one-cut multi-groove processing of a quartz rod. Background Art

[0002] Solar photovoltaic cells are a new type of battery that converts sunlight directly into electrical energy. Currently, silicon photovoltaic cells based on silicon are commonly used, including single-crystal silicon, polycrystalline silicon and amorphous silicon photovoltaic cells. In the preparation process of solar photovoltaic cells, silicon wafers need to go through processes such as texturing, diffusion, etching, coating and printing in sequence. Quartz boat is a commonly used wafer carrier. Multiple quartz boats are placed on a quartz boat holder and sent into the process furnace through the quartz boat holder. During the process, the more complete the contact between the process gas and the surface of the silicon wafer, the more significant the process effect. During the processing of silicon wafers, the silicon wafers need to be placed in a dedicated quartz boat slot rod slot for subsequent processing.

[0003] At present, most domestic manufacturers use a one-cut-one-groove grooving method to process grooved rods. Since conventional grooved rods need to grind at least hundreds of grooves on the quartz rod, and the special properties of quartz materials greatly increase the difficulty of grinding. In order to improve efficiency, our company has developed a grooving device that can make multiple grooves with one cut. After the quartz rod is grooved by this device, the top of the I-shaped groove needs to be chamfered to make it Y-shaped to facilitate the use of the quartz boat. The existing one-cut-one-groove trimmer cannot meet the demand, so a new trimmer is needed to solve this problem. Utility Model Content

[0004] The utility model aims to provide a diamond trimmer for processing multiple grooves of a quartz rod with one cut, which has the effect of trimming multiple rod grooves of a grooved quartz rod at the same time to make it into a Y-shaped opening.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A diamond dresser for one-cut multi-groove processing of a quartz rod comprises a main shaft, on which a plurality of blades are coaxially fixedly connected, the blades have equal diameters, and the intervals between adjacent blades are equal. Both sides of the blade edges are provided with inclined chamfers, and the blades are made of diamond.

[0007] As a further configuration of the utility model, the thickness of the blade is greater than the thickness of the quartz rod groove.

[0008] As a further configuration of the utility model, the number of the blades is equal to the number of grooves required to be formed in the quartz rod.

[0009] The beneficial effects of the utility model are:

[0010] When in use, the spindle is connected to an external power device to control the rotation of the spindle. The spindle drives the diamond blade to rotate and drives the spindle up and down at the same time. When the rapidly rotating blade passes through the rod groove that has been opened on the quartz rod, the rod groove of the quartz rod can be chamfered, thereby grinding the I-type groove into a Y-type groove.

[0015] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] A diamond dresser for one-cut multi-groove processing of a quartz rod comprises a main shaft 1, on which a plurality of blades 2 are coaxially fixedly connected, the blades 2 have equal diameters, and adjacent blades 2 have equal intervals, and both sides of the edges of the blades 2 are provided with inclined chamfers, and the blades 2 are made of diamond.

[0018] Furthermore, the thickness of the blade 2 is greater than the thickness of the quartz rod groove.

[0019] Furthermore, the number of the blades 2 is equal to the number of grooves required in the quartz rod.

[0020] The working principle of this embodiment is as follows:

[0021] When in use, the spindle 1 is connected to an external power device to control the rotation of the spindle 1. The spindle 1 drives the diamond blade 2 to rotate and drives the spindle 1 to move up and down at the same time. When the rapidly rotating blade 2 passes through the rod groove that has been opened on the quartz rod, the rod groove of the quartz rod can be chamfered, thereby grinding the I-shaped groove into a Y-shaped groove.
