Detailed ways

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

As shown in Figures 1 and 2, a multifunctional wire cutting machine is the first embodiment of the present invention, including a main roller cutting mechanism and a coordinate driving mechanism.

The main roller cutting mechanism is arranged above the worktable, and the main roller cutting mechanism includes a cutting steel wire 11 , a main roller 2 , a guide wheel and a main roller motor 6 . Usually, two main rollers 2 arranged in parallel can be designed, and several sets of guide wheels are designed in groups corresponding to the upper sides of the two sides of the main roller 2 . The guide wheels are distributed in groups along the axial direction of the main roller 2 at intervals, and the cutting steel wire 11 is tensioned and connected between each group of guide wheels and the main roller 2 . In order to facilitate multiple cuts on the same workpiece at the same time, and the distance between different cutting wires can be adjusted, the guide wheel is a universal adjustment guide wheel 1, and the surface of the main roller is spaced with accommodating cutting steel wires 11. duct. During cutting, the number of sets of guide wheels for installing the cutting wire should be selected according to the number of cuts, and the angle of each set of universal adjustment guide wheels 1 can be adjusted according to the spacing requirements of cutting, so that the cutting steel wire can be tensioned with the wire groove below according to the cutting spacing. .

The winding method of the cutting steel wire can be selected according to the actual use requirements. As shown in FIG. 5 , the cutting wire 11 is wound only in the wire groove of the main roll 2, and can be used in the case of cutting thin sheets. In the case where thick slices need to be cut, the winding method shown in Figure 6 can be used according to the requirements of the spacing between the cutting lines. The wire grooves with the required spacing are selected, and the angle of the guide wheel 1 can be adjusted universally above so that the The cutting steel wire 11 can be extended correspondingly obliquely and the corresponding wire groove can be selected for winding. At the same time, these two different winding methods can also expand the height limit of the workpiece to be cut. When the winding method shown in FIG. 5 is adopted, the maximum height of the workpiece to be cut does not exceed the distance between the clamping plane of the rotary table 3 and the cutting steel wire 11 located under the main roller. When the winding method shown in FIG. 6 is adopted, the cutting The maximum height of the workpiece can be expanded, not limited to the main roller, but can be up to the position of the cutting steel wire 11 on the universal adjustment guide wheel 1, which can be selected as needed in use.

The coordinate drive mechanism includes an X-axis servo sliding mechanism 4 and a Y-axis feeding and jacking mechanism. A worktable is fixed on the slider of the X-axis servo sliding mechanism 4 . The workbench is a rotary workbench 3, and the rotary workbench 3 is driven to rotate by a worm gear. On the rotary table 3, a fixture, such as a chuck, is selected according to the clamping requirements of the workpiece. The rotation axis of the rotary table 3 is the third axis. In use, the rotary table 3 clamps the workpiece for rotation. On the one hand, it performs rotary cutting. On the other hand, it can also turn the rotary table 3 to a pre-adjusted position for some materials with crystal orientation requirements after clamping. Angle, the function of correcting the clamping error. For example, when cutting materials such as silicon rods, since the growth of silicon is directional, during wire cutting, after clamping the workpiece, it is necessary to drive the workpiece to rotate through the rotary table 3 to compensate the crystal orientation angle. Adjust the workpiece rotation to the appropriate cutting angle.

At the same time, in the actual design, the X-axis servo sliding mechanism 4 can be designed as a motion mechanism that moves along the axial direction of the main roller as required. The motion mechanism can be selected as a carriage, rolling guide, screw motion pair, Gear transmission mechanism, etc.

The Y-axis feeding and jacking mechanism includes a Y-axis feeding table 7 and a jacking mechanism that controls the lifting and lowering of the Y-axis feeding table 7 . The coordinate drive mechanism further includes a fourth axis angle rotation mechanism 5 . The fourth-axis angle rotation mechanism 5 is arranged on the Y-axis feed table 7 and drives the rotary table 3 to adjust the angle relative to the horizontal plane.

The fixing bracket 9 is fixed on the Y-axis feeding table 7 , and the X-axis servo sliding mechanism 4 is fixed above the arc-shaped plate 8 . The power mechanism can be selected as required, as long as it can drive the arc-shaped plate 8 to move along the arc-shaped track. In order to improve the accuracy of movement, the power mechanism here may preferably be a servo motor. When the arc-shaped plate 8 slides along the arc-shaped track under the action of the power mechanism, the X-axis servo sliding mechanism 4 and the rotary table 3 above the arc-shaped plate 8 also move synchronously to realize the angle adjustment of the workpiece relative to the horizontal plane (along the arc-shaped track). perform arc adjustment).

At the same time, on the same Y-axis feed table 7, multiple sets of fourth-axis angle rotation mechanisms 5 can also be designed as needed, and the fourth-axis angle rotation mechanisms 5 are arranged axially along the main roller 2.

In this way, when the same main roller 2 and the same cutting steel wire 11 are cutting, multiple sets of rotating worktables 3 can be simultaneously driven for cutting, which facilitates simultaneous processing of multiple workpieces. At the same time, the multi-station designed fourth-axis angle rotation mechanism 5 can be adjusted during operation to play the role of automatic tool setting. In use, multiple fourth-axis are designed on the same Y-axis feed table 7 The angle rotation mechanism 5 can process multiple workpieces synchronously, and a group or a smaller number of fourth-axis angle rotation mechanisms 5 are designed on the same Y-axis feed table 7. At the same time, the Y-axis feed table 7 is long enough to design If there are multiple stations, the same workpiece can have multiple stations on the machine. After one clamping, multiple processing is performed according to the stations, which can effectively avoid errors caused by multiple clamping and further improve the processing accuracy.
