Description

Technical Field

[0001] The utility model relates to the technical field of quartz rod processing, in particular to a clamp 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-slot method to process slotted rods. Since conventional slotted rods need to grind at least hundreds of slots on the quartz rod, and the special properties of quartz materials greatly increase the difficulty of grinding. In order to improve the efficiency of slotting, our company has developed a slotting device with one cutter and multiple slots. For the one-cut multiple slots device, a specific fixture is required to clamp the quartz rod. The existing fixtures all use a single clamping fixture for clamping, which reduces the processing efficiency. In order to increase the clamping efficiency, a new fixture is needed to cooperate with the one-cut multiple slots slotting device. Utility Model Content

[0004] The utility model aims to provide a clamp for processing multiple grooves of a quartz rod with one cutter, which has the effect of high clamping efficiency.

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

[0006] A clamp for processing multiple grooves with one cutter on a quartz rod comprises a clamping plate, on which a plurality of placement grooves with U-shaped cross-sections are provided, the plurality of placement grooves are arranged in parallel and spaced apart, and the placement grooves penetrate the clamping plate along the length direction.

[0007] As a further configuration of the utility model, the clamping plate is an elongated plate, and an inclination of an angle a is provided between the length direction of the placement groove and the width direction of the clamping plate, and the angle a is equal to the angle between the cutting groove and the axis of the quartz rod.

[0008] By adopting the above technical solution and setting the inclination angle, it is possible to ensure that a predetermined angle is achieved between the cut rod groove and the axis of the quartz rod during processing.

[0009] As a further configuration of the utility model, the width of the placement groove matches the diameter of the quartz rod.

[0010] By adopting the above technical solution, when the width of the placement groove matches the diameter of the quartz rod, after the quartz rod is placed in the placement groove, the quartz rod will not be offset and can be pre-positioned.

[0011] As a further configuration of the utility model, the depth of the placement groove is greater than the radius length of the quartz rod.

[0012] The beneficial effects of the utility model are:

[0013] During the slotting process, a single quartz rod is placed in the placement groove, and the ends of the quartz rod are controlled to be flush. Then, pressure is applied from both sides of the clamping plate through an external pressure device. Under higher pressure, the clamping plate squeezes the quartz rod to achieve clamping of the quartz rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.

[0020] Example

[0021] A fixture for processing multiple grooves in a quartz rod with one cutter comprises a clamping plate 1, on which a plurality of placement grooves 2 with U-shaped cross sections are opened, the plurality of placement grooves 2 are arranged in parallel and spaced apart, and the placement grooves 2 penetrate the clamping plate 1 along the length direction.

[0022] Furthermore, the clamping plate 1 is a long plate, and an inclination of an angle a is provided between the length direction of the placement groove 2 and the width direction of the clamping plate 1, and the angle a is equal to the angle between the cutting groove and the axis of the quartz rod.

[0023] By setting the inclination angle, it is possible to ensure that a predetermined angle is achieved between the cut rod groove and the axis of the quartz rod during processing.

[0024] Furthermore, the width of the placement groove 2 matches the diameter of the quartz rod.

[0025] When the width of the placement groove 2 matches the diameter of the quartz rod, after the quartz rod is placed in the placement groove 2, the quartz rod will not be offset and can be pre-positioned.

[0026] The depth of the placement groove 2 is greater than the radius length of the quartz rod.

[0027] The working principle of this embodiment is as follows:

[0028] During the grooving process, a single quartz rod is placed in the placement groove 2, and the ends of the quartz rod are controlled to be flush. Then, pressure is applied from both sides of the clamping plate 1 through an external pressure device. Under higher pressure, the clamping plate 1 squeezes the quartz rod to achieve clamping of the quartz rod.

[0029] Specifically, the external pressure device applies pressure from the side of the width of the clamping plate 1, so that the placement groove 2 of the clamping plate 1 is squeezed, thereby achieving a clamping effect.
