Description

Immersion groove

Technical Field

The utility model belongs to the technical field of crystal silicon processing, specifically speaking relates to an immerse groove.

Background

The crystalline silicon is an important component for realizing photoelectric conversion of the solar cell panel, and can be processed into a crystalline silicon wafer meeting the standard through a plurality of procedures. In the processing process of crystalline silicon, the processing efficiency and the cutting quality are the main concerns in the field of single/multi-wire diamond wire cutting. Spraying is adopted as a main cooling mode in the traditional processing process, the temperature of a cutting area can be reduced to a certain extent by adopting the traditional nozzle spraying and pouring modes, and chips are washed away, but the wire diameter of the diamond wire is extremely small, so that the wire diameter can be as low as 50 mu m in the aspect of multi-wire cutting, and the single wire cutting can also be below 120 mu m. Therefore, the cutting seam is extremely small, the capability of cutting fluid brought into a cutting area in a thin line is limited, sufficient cooling and lubricating effects cannot be guaranteed, and particularly the lubricating capability of the cutting fluid is not fully exerted, so that the cutting quality and the machining efficiency are limited to a certain extent. Therefore, in the case of extremely small slits, how to effectively cool the diamond wire is a problem to be solved.

SUMMERY OF THE UTILITY MODEL

To prior art's all sorts of insufficiencies, now provide the groove of immersing that holds the coolant liquid, can effectually cool off for the buddha's warrior attendant line.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an immerse groove, sets up between two parallel cutting rollers, and its below that is located the diamond wire net of laying on the cutting roller, immerse the upper portion opening in groove, it includes lateral wall and the tank bottom that is connected with the lateral wall, lateral wall and tank bottom enclose into the space that holds the cutting fluid, and the upper portion of a set of lateral wall is provided with the wire casing, supplies the diamond wire to run through.

Further, the bottom of the tank is provided with a protrusion, and the protrusion faces the opening of the immersion tank, facilitating the collection of chips toward the bottom edge of the tank.

Further, the longitudinal section of the wire groove is rectangular.

Furthermore, a plurality of drainage ports are arranged at the joint of the side wall and the bottom of the groove and used for discharging cutting fluid.

Furthermore, the longitudinal section of the drainage port is rectangular, and the drainage ports are arranged at intervals.

Further, the immersion groove has a rectangular longitudinal section, and the drain opening is provided along the longitudinal direction of the immersion groove.

The utility model has the advantages that:

1. the wire casing is seted up on immersing groove upper portion for hold the buddha's warrior attendant line, effectively avoid the lateral wall to interfere buddha's warrior attendant line, simple structure.

2. The bottom of the immersion groove is provided with a drainage port for discharging the chips and cutting fluid precipitated on the bottom of the immersion groove.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

The first embodiment is as follows:

as shown in fig. 1, an immersion bath is provided between two parallel cutting rolls and is located below a diamond wire mesh laid on the cutting rolls. The immersion groove comprises a side wall 1 and a groove bottom 2 connected with the side wall 1, the side wall 1 is connected with the edge of the groove bottom 2 in a sealing mode and encloses a space for containing cutting fluid, and an opening is formed in the upper portion of the immersion groove and used for immersing the diamond wire in the cutting fluid. For the erection of diamond wire, the upper portion of lateral wall 1 that corresponds below the diamond wire is provided with the wire casing 3 that supplies the diamond wire to run through, simultaneously, because crystal silicon can produce the smear metal at the in-process of cutting, consequently, be provided with a plurality of discharge ports 4 in the edge of lateral wall 1, supply the smear metal to discharge, discharge port 4 sets up along the bottom edge interval of lateral wall 1. In order to facilitate the collection of the chips at the bottom and the outflow of the chips with the cutting fluid, the bottom of the groove bottom 2 is provided with a projection, and the projection faces the opening.

In this embodiment, immerse the groove and the vertical section of outlet all becomes the rectangle, and immerse groove and cutting roller parallel arrangement, outlet 4 sets up along the length direction interval of immersing the groove, simultaneously, the vertical section of tank bottom 2 becomes triangle-shaped, and the smear metal piece of being convenient for slides to the edge of tank bottom 2, and then flows from outlet 4. And a nozzle is arranged above the diamond wire mesh and used for supplementing the cutting fluid lost in the immersion groove. In other embodiments, the longitudinal cross-section of the immersion tank and the longitudinal cross-section of the tank bottom 2 can also be of other shapes.

When the immersion groove is used, the immersion groove is filled with cutting fluid, the diamond wire penetrates through the wire groove 3 and is immersed in the cutting fluid, the crystalline silicon is in contact with the diamond wire from the upper part of the diamond wire, in the cutting process, the cutting fluid in the immersion groove is brought into a cutting area, the lubricating effect can be effectively achieved for the cutting of the crystalline silicon, heat generated by friction between the diamond wire and the crystalline silicon is taken away, meanwhile, generated cutting chips slide to the edge of the groove bottom 2, and finally the immersion groove is discharged along with the cutting fluid through the drainage port 4. In this embodiment, the nozzles are arranged in two sets, and the two sets of nozzles are respectively arranged on two sides of the crystalline silicon.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
