Description

Cutting nozzle and wire cutting machine cutting liquid filtering jet device

The present invention relates to a filter nozzle and a filter jet device, and more particularly to a filter head filter jet spray device suitable for filtering a cutting liquid and spraying the cutting liquid to a filter head of a wire cutter and a wire cutter.

With the rise of environmental awareness, the concept of energy conservation and carbon reduction has gradually attracted the attention of the audience. The development and utilization of renewable energy has become the focus of active development in all countries of the world. Among the renewable energy sources, because solar energy is available everywhere, and unlike other energy sources (such as petrochemical energy and nuclear energy), it will generally pollute the earth. Therefore, solar energy and various devices that can convert sunlight into electric energy are currently the star industry. .

In the process of solar wafers, a long strip of ingots is cut through a wire cutter in a wafer cutting chamber to cut a plurality of solar wafers. During this cutting process, the local area of the ingot is lost due to factors such as the width of the cutting line itself, and the damaged wafer is mixed in the cutting liquid. In addition, since the conventional nozzle is quite cumbersome, it is necessary to lock the device end of the inline cutting machine with a considerable number of screws. If the nozzle is to be removed, it is quite difficult to remove, and it is easy to cause the screw to slip. Therefore, in order to avoid the broken wafers clogging the pipeline through which the cutting fluid flows, and facilitating disassembly and cleaning, it has become one of the problems that researchers in this field are eager to solve.

The novel creation provides a filter nozzle that is capable of filtering debris in the cutting fluid as it passes through to prevent debris from clogging the nozzle.

The novel creation provides a cutting liquid filtering jet device of a wire cutting machine, which not only can filter the debris in the cutting liquid, but also is easy to disassemble to the seat body, which is quite convenient for cleaning.

The filter nozzle of the present invention is suitable for being arranged on a wire cutter and adapted to filter the cutting fluid and spray the cutting liquid to the wire cutter. The filter nozzle comprises a nozzle body and a three-dimensional filter. The nozzle body includes a plurality of nozzles. The three-dimensional filter is disposed on the nozzle body.

In an embodiment of the present novel creation, the above-described three-dimensional screen comprises two planar blocks that are connected and non-coplanar, and form two sides of the hollow triangular prism.

In an embodiment of the present invention, the mesh aperture of the stereoscopic screen is smaller than the aperture of each nozzle.

In an embodiment of the present invention, the nozzle body extends along a first axis, and the nozzles on the nozzle body are arranged along the first axis in at least one row, between the two adjacent nozzles of each row. The distance gradually increases along the first axis.

The cutting liquid filtering jet device of the wire cutting machine of the present invention comprises a body and a filtering nozzle detachably disposed on the seat body. The filter nozzle includes a nozzle body and a stereo filter. The nozzle body includes a plurality of nozzles. The three-dimensional filter is disposed on the nozzle body.

In an embodiment of the present invention, the seat body includes a receiving recess extending along a first axis, and the filter head is removably disposed along the first axis in the receiving recess.

In an embodiment of the present novel creation, the above-described three-dimensional screen comprises two planar blocks that are connected and non-coplanar, and form two sides of the hollow triangular prism.

In an embodiment of the present invention, the stereoscopic screen has a hollow semi-cylindrical shape.

In an embodiment of the present invention, the mesh aperture of the stereoscopic screen is smaller than the aperture of each nozzle.

In an embodiment of the present invention, the nozzle body extends along a first axis, and the nozzles on the nozzle body are arranged along the first axis in at least one row, between the two adjacent nozzles of each row. The distance gradually increases along the first axis.

Based on the above, the cutting liquid filtering jet device and the filtering nozzle of the wire cutting machine of the present invention are configured to dispose the three-dimensional filter on the nozzle body, and the cutting liquid mixed with the debris passes through the three-dimensional filter and then through the nozzle of the nozzle body. The probability that the debris mixed in the cutting fluid blocks the nozzle of the nozzle body can be reduced. The mesh aperture of the three-dimensional filter is smaller than the aperture of each nozzle. Therefore, the larger size debris is blocked on the three-dimensional filter to ensure that the size of the debris flowing into the nozzle of the nozzle body is smaller than the aperture size of the nozzle. Can pass through the spout. The three-dimensional filter can be in the form of two sides of the hollow triangular column or a hollow semi-cylindrical shape, and the three-dimensional design can increase the filtering area and prevent the debris from covering the nozzle of the nozzle body, thereby affecting the flow rate of the cutting liquid. In addition, compared with the conventional nozzle, the overall length of the nozzle is relatively heavy, and it is necessary to lock the device end of the online cutting machine with a relatively large number of screws, which is inconvenient to disassemble. The cutting fluid filtering jet device of the wire cutter of the present invention will be used to The filter nozzle is divided into two parts, the seat body is fixed on the device end, and the filter nozzle is replaceably arranged in the accommodating groove along the first axis.

The above described features and advantages of the present invention will become more apparent and understood from the following description.

In general, the wire cutter of a solar wafer needs a cutting liquid for cooling and lubrication during the cutting process of the ingot. During the cutting process, the local area of the ingot is due to the width of the cutting line itself. If it is lost due to other factors, the damaged wafer will be mixed in the cutting fluid. Although the cutting fluid is first filtered through the filter before being recycled back to the storage tank, some of the finer fragments will still flow back into the storage tank together with the cutting liquid through the filter, and then if there are fine fragments mixed together When the cutting liquid is sprayed through the nozzle to the wire cutter, the nozzle is blocked by the debris and affects the flow of the cutting fluid.

The cutting liquid filtering jet device of the wire cutting machine of the present invention can be assembled above a wire cutting machine (not shown), and the wire cutting machine can be a wire cutting machine for cutting a solar crystal ingot. The cutting liquid filtering jet device of the wire cutter of the present invention can effectively reduce the clogging of the nozzle when the cutting fluid flows, so that the cutting fluid can be smoothly sprayed to the wire cutter. This will be described in detail below.

Figure 2 is a schematic illustration of the different perspectives of Figure 1. Fig. 3 is a schematic view showing the seat body of the cutting liquid filtering jet flow device of the wire cutter of Fig. 1. 4 is a schematic view of a filter head of a cutting fluid filtration jet device of the wire cutter of FIG. 1. Figure 5 is a schematic illustration of the nozzle body of Figure 4. Figure 6 is a schematic illustration of the three-dimensional screen of Figure 4.

Referring to FIGS. 1 to 6 , the cutting fluid filtering jet device 10 of the wire cutting machine includes a body 20 and a filter head 100 detachably disposed on the base body 20 . The seat body 20 can be fixed to the device end 5 of the wire cutter by means of screwing. Of course, the manner in which the base body 20 is fixed to the device end 5 of the wire cutter is not limited thereto. The seat body 20 includes a receiving recess 22 extending along a first axis A1. As shown in FIGS. 1 and 2, the filter head 100 is removably disposed along the first axis A1 in the receiving recess 22. It should be noted that, in FIG. 1 and FIG. 2 , in order to show that the filter head 100 is detachably disposed on the seat body 20 , a schematic view of the filter head 100 being disassembled to half is specifically illustrated. After the actual installation is completed, the filter head 100 is filtered. Will be housed entirely within the receiving recess 22 of the base 20, and for clarity of the filter head 100, the device end 5 of the wire cutter of Figure 1 is shown in phantom.

Compared with the conventional nozzle (not shown), the overall length of the nozzle (not shown) is relatively heavy, and it is necessary to lock the device end 5 of the inline cutting machine with a relatively large number of screws, which is inconvenient to disassemble, and the cutting liquid filtering jet device of the wire cutting machine of the embodiment 10, the seat body 20 and the filter nozzle 100 are separated into two pieces, and the filter head 100 is replaceably disposed in the accommodating recess 22. Since the filter head 100 is light in weight, only one or two screws are needed to be fixed to the base body 20, It is quite easy to disassemble and it is easier to carry out subsequent cleaning procedures.

In the embodiment, the filter head 100 includes a head body 110 and a three-dimensional screen 120. The nozzle body 110 includes a plurality of nozzles 112 through which a cutting fluid (not shown) can be sprayed onto the wire cutter. The three-dimensional screen 120 is disposed on the nozzle body 110 and covers the nozzles 112. The steric screen 120 can increase the area of filtration and prevent debris from covering the spout 112 of the nozzle body 110, thereby affecting the flow of cutting fluid. In the present embodiment, the three-dimensional screen 120 includes two planar blocks that are connected and non-coplanar to form two sides of the hollow triangular prism. Of course, the form of the stereoscopic screen 120 is not limited thereto.

In the present embodiment, the mesh aperture of the stereoscopic screen 120 is smaller than the aperture of each of the nozzles 112. This configuration allows larger-sized fragments to be blocked on the stereoscopic screen 120 to ensure flow into the nozzles 112 of the nozzle body 110. The size of the fragments is smaller than the aperture size of the spout 112 and can pass through the spout 112. The filter head 100 of the embodiment is configured to dispose the three-dimensional screen 120 on the nozzle body 110, and the cutting liquid mixed with the debris first passes through the three-dimensional screen 120 and then passes through the nozzle 112 of the nozzle body 110, thereby reducing mixing in the cutting fluid. The debris blocks the probability of the spout 112 of the nozzle body 110.

In addition, as shown in FIG. 5, in the present embodiment, the head body 110 extends along the first axis A1, and the nozzles 112 on the head body 110 are arranged in at least one row along the first axis A1 (arranged in FIG. 5). In two rows, the distance between the two adjacent nozzles 112 of each row gradually increases along the first axis A1. More specifically, in FIG. 5, the cutting liquid flows to the left from the right along the first axis above the nozzle body 110, and flows downward from the nozzle 112 of the head body 110 through the nozzle 112, in order to make the whole The flow rate of the cutting liquid discharged from the discharge port 112 of the row is uniform, and the distance between the two adjacent nozzles 112 on the right side of the drawing is larger in each row.

In this way, when the cutting liquid flows to the left from the right along the first axis A1 above the nozzle body 110, although the cutting liquid on the right side near the drawing surface is large, part of the cutting liquid passes through the right. The square spout 112 will flow downward, so that the cutting fluid flowing to the left side is reduced, but the number of the spouts 112 on the right side of the drawing is small and the spacing is large, and the number of the spouts 112 on the left side of the drawing is large and the spacing is small. The flow rate of the cutting liquid that can pass through the nozzle 112 on the right side of the drawing surface is close to the flow rate of the cutting liquid that can pass through the nozzle 112 on the left side of the drawing surface, so that the flow rate of the cutting liquid discharged from the entire row of nozzles 112 flows. Uniform to achieve the effect of controlling the flow rate of the cutting fluid.

7 is a schematic illustration of a three-dimensional screen of a filter head in accordance with another embodiment of the present invention. Referring to FIG. 7, the main difference between the three-dimensional screen 220 of FIG. 7 and the three-dimensional screen 120 of FIG. 6 is that the three-dimensional screen 220 of FIG. 7 has a hollow semi-cylindrical shape. The three-dimensional screen 220 of the present embodiment can increase the filtering area by the form of a three-dimensional structure, and avoids the debris covering the nozzle 112 of the nozzle body 110 (shown in FIG. 5), thereby affecting the flow rate of the cutting liquid. Of course, the form of the stereoscopic screen 220 is not limited to the above, as long as it is in a non-planar form.

In summary, the cutting liquid filtering jet device and the filtering nozzle of the wire cutting machine of the present invention are arranged on the nozzle body through the three-dimensional filter screen, and the cutting liquid mixed with the debris passes through the three-dimensional filter mesh and then through the nozzle of the nozzle body. Moreover, the probability that the debris mixed in the cutting liquid blocks the nozzle of the nozzle body can be reduced. The mesh aperture of the three-dimensional filter is smaller than the aperture of each nozzle. Therefore, the larger size debris is blocked on the three-dimensional filter to ensure that the size of the debris flowing into the nozzle of the nozzle body is smaller than the aperture size of the nozzle. Can pass through the spout. The three-dimensional filter can be in the form of two sides of the hollow triangular column or a hollow semi-cylindrical shape, and the three-dimensional design can increase the filtering area and prevent the debris from covering the nozzle of the nozzle body, thereby affecting the flow rate of the cutting liquid. In addition, compared with the conventional nozzle, the overall length of the nozzle is relatively heavy, and it is necessary to lock the device end of the online cutting machine with a relatively large number of screws, which is inconvenient to disassemble. The cutting fluid filtering jet device of the wire cutter of the present invention will be used to The filter nozzle is divided into two parts, the seat body is fixed on the device end, and the filter nozzle is replaceably arranged in the accommodating groove along the first axis. The filter nozzle is light in weight and can be fixed to the seat body only by one or two screws. Quite convenient for subsequent cleaning procedures.
