Problems solved by technology

[0005] The purpose of the present invention is to provide a diamond wire winding method, which can solve the problem of unstable single-point hooking existing in the traditional diamond wire winding method, and avoid the problem that the diamond wire at the edge of the I-shaped wheel does not reach the edge. Sagging phenomenon
[0006] In the present invention, when the diamond wire is at the edge of the I-shaped wheel, the rotation speed of the cable arranging shaft is paused for a short time, so that the diamond wire and the surface of the I-shaped wheel form a line segment contact, thereby realizing the stable state brought by the friction force of the line segment , to solve the problem of unstable single-point hooking existing in the existing diamond wire winding method

Embodiment 1

[0036] The winding method of the present invention comprises:

[0037] Step 1: Align the side of the I-shaped wheel, and determine the left and right edge positions of the cable;

[0038] The second step: the diamond wire wheel, using adhesive tape to bond the diamond wire to the middle cross section of the cylindrical surface of the I-shaped wheel;

[0039] Step 3: Start the winding device, set the speed of the winding shaft and the spacing of the wires, so that the spacing of the wires is stacked on the surface of the I-shaped wheel according to the set algorithm to produce a stable finished product;

[0040] Step 4: Shut down at fixed length, reach the preset product length, shut down, inspect and pack for shipment.

[0041] Among them, in the third step, the specific steps of setting the speed of the winding shaft and the speed of the winding shaft are as follows.

Embodiment approach

[0043] As an embodiment of the present invention, the speed of the winding shaft can be set at 10-30 m / min. As a specific embodiment of the present invention, the length and diameter of the I-shaped wheel are 200mm, the speed of the winding shaft is 10m / min, and when the diamond wire spacing is 0.1mm, the speed of the third stage in the forward direction is 1.6 / 10000 of the speed of the winding shaft , the forward third-stage speed is 1.6mm / min, the forward second-stage speed and the forward fourth-stage speed are 2.4mm / min (1.5 times the forward third-stage speed), and the forward The maintenance time of the first stage speed is 1.8s, and the maintenance time of the forward second stage speed and the forward fourth stage speed is 1.8s. The calculation relationship is shown in Table 1.

Abstract

The invention provides a diamond wire winding method. The winding method is used for winding a diamond wire on a spool so that a section of line segment contact can exist between the diamond wire andthe surface of the spool at the edge positions of the two ends of the spool. The winding method specifically includes the steps that the speed of a wire arrangement shaft and the speed of a winding shaft are set; and specifically, by shortly stopping the rotating speed of the wire arrangement shaft when the diamond wire is at the edge positions of the spool, the line segment contact can be achieved between the diamond wire and the surface of the spool, and therefore the stable state caused by line segment friction force is achieved and the problem that in the existing diamond wire winding manner, single-point hitching is unstable is solved.

Description

technical field [0001] The invention relates to the technical field of controlling the winding mode of a diamond wire on an I-shaped wheel, in particular to a diamond wire winding method. Background technique [0002] In recent years, photovoltaic, semiconductor, LED and other industries have developed rapidly, and the application fields of precious hard and brittle materials such as silicon wafers and sapphires have become increasingly widespread. As a tool for cutting hard and brittle materials, diamond wire saws have good slicing quality, high cutting efficiency, With the advantages of no pollution and low cost, it has been developed rapidly. [0003] After the diamond wire is produced, it is wound on the I-shaped wheel, specifically, it is spirally wound on the surface of the I-shaped wheel through multi-layer superposition. This winding method is realized by a simple speed control mode with a fixed ratio between the winding shaft speed and the winding shaft speed (the ...
