Processing method of plate

field of invention The invention relates to a processing method for dividing a plate into a plurality of strips.

Background of the invention Sometimes, a plate-shaped object formed of a composite material of a different material, such as a metal plate and a resin plate, is cut by a processing mechanism such as a cutting blade. In such cutting, as disclosed in, for example, Patent Document 1, the back side of the plate-like object is attached to the supporting member with a hot-melt type wax, and the state is firmly held. prior art literature patent documents

Patent Document 1: Japanese Patent Laid-Open No. 2013-129024

Summary of the invention The problem to be solved by the invention Among the composite materials, for example, a composite material in which a relatively soft and thick resin plate is laminated with respect to a thin metal plate is used as an object of cutting. When such a composite material is cut, even if the backside is firmly fixed with wax, the rigidity of the composite material as a whole is still low, so there is a problem that it falls over the singulated workpiece during the cutting process.

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a board that can prevent individual strip-shaped pieces from falling during cutting even if the board-shaped object is a composite material including a soft layer. The processing method of the shape. means to solve problems

The processing method of the plate-shaped object of the present invention is a processing method of a plate-shaped object having a product area, and is characterized in that it is composed of the following steps: an attaching step, attaching a plate of remaining size having a remaining area on the outer periphery of the work-in-progress area to the holding member; In the step of cutting the product area, after the attaching step is carried out, the processing mechanism is used to cut into the middle of the holding member from the remaining area on one side above the remaining size of the plate, and cut the product area along the predetermined dividing line in the first direction, And raising the processing mechanism in the remaining area on the other side, thereby leaving the non-cutting part in the remaining area on one side and the other side and cutting the product area along the planned dividing line in the first direction; and In the dividing step, after the product area cutting step is performed, the remaining area in the second direction perpendicular to the first direction is cut and removed by a processing mechanism to be divided into individual strips.

According to this method, since non-cut portions remain in the remaining regions located on both sides of the extending direction of the planned dividing line during cutting along the planned dividing line, it becomes possible to connect the strip-shaped sheets through the remaining regions. Thus, even if the board is a composite material including a soft layer and the rigidity becomes low, it is possible to prevent the strip-like sheet from falling down in the product region cutting step. This prevents the end faces of the strips from becoming trapezoidal or parallelogram-shaped when the strips are divided into individual strips by cutting to remove the excess area, and becomes a square with good precision, and can achieve stable processing quality. change. Invention effect

According to the present invention, even if the plate-shaped object is a composite material including a soft layer, it is possible to prevent individual strip-shaped pieces from falling during cutting.

form for carrying out the invention Hereinafter, with reference to the accompanying drawings, the processing method of the plate-shaped object according to the embodiment will be described with reference to FIGS. 1 to 7 . FIG. 1 is an explanatory view of the attaching step, FIGS. 2 to 5 are explanatory views of the product region cutting step, and FIGS. 6 and 7 are explanatory views of the dividing step. In addition, the procedure shown in each figure mentioned above is an example only, and is not limited to this structure.

First, as shown in Fig. 1, the attaching step is carried out. In the attaching step, first, the remaining size plate (plate) 10 is prepared. The remaining size plate 10 is prepared by preparing a substrate (not shown) of a size larger than its planar size, and is formed by cutting said substrate into a rectangle. In the present embodiment, the plate-shaped object 10 of the remaining size is a composite material in which the resin layer 10b formed of a resin plate is laminated on both sides in the thickness direction of the metal layer 10a formed of a metal plate. Although not particularly limited, the resin layer 10b is formed relatively thicker than the metal layer 10a, and is formed of a relatively soft material.

The remaining size plate 10 has a product region 12 and a remaining region 14 located on the outer periphery of the product region 12 . In addition, the remaining size plate 10 has a plurality of dividing lines 16 formed at predetermined intervals. In FIG. 1 , the dividing lines 16 are shown as dotted lines for convenience of description. Here, in the remaining size plate 10, the extending direction of the planned dividing line 16 in the view of the upper surface is defined as the first direction, and the direction perpendicular (orthogonal) to the first direction is defined as the second direction. In the remaining size plate 10, the predetermined width region (area shown in halftone dots) along both ends of the first direction is defined as the remaining region 14, and the region between the remaining regions 14 is defined as the product region 12. .

Furthermore, the dots shown in the drawings after FIG. 1 are drawn for convenience so that the area 12 and the remaining area 14 of the product can be distinguished and visually recognized. In this embodiment, although the material and structure of the product area|region 12 and the remainder area|region 14 were made the same, it is not limited to this, You may make it a different structure.

In the attaching step, the prepared plate-shaped object 10 of the remaining size is attached to the plate-shaped holding member 19 made of the base material through the hot-melt wax 18, so as to hold the plate-shaped object 10 of the remaining size In the state of holding member 19. As the holding member 19 , any member can be used as long as it can hold the plate-shaped object 10 with an excess size in a flat state, and for example, a carbon plate, a silicon plate, a glass plate, or a metal plate can be used. In addition, instead of the wax 18, as long as the adhesiveness can be reduced by external stimulation, it is also possible to use, for example, an ultraviolet curable resin or a thermally peelable adhesive tape in which a foam material is dispersed.

After the attaching step is carried out, as shown in FIG. 2 , the product region cutting step is carried out in which a cutting blade (processing mechanism) 20 is used to cut into the product region 12 of the plate-like object 10 with the remaining size. The cutting blade 20 is disposed on the front end of the rotatable main shaft 22 . In the step of cutting the product area, the remaining size plate 10 is sucked and held on the work clamp (not shown) via the holding member 19 . The work clamping table is moved in the X direction by the feed mechanism, and is rotatably arranged.

After sucking and holding the plate 10 of the remaining size, the plate 10 of the remaining size is aligned. This alignment is to position the plate-shaped object 10 with the remaining size so that the first direction (refer to FIG. 1 ) which is the extending direction of the planned dividing line 16 becomes the cutting feeding direction (X direction). At this time, in the present embodiment, the remaining regions 14 are arranged on both sides in the X direction on the plate-shaped object 10 having an remaining size.

As shown by the two-dot chain line in FIG. 3 , the cutting blade 20 is positioned directly above the remaining region 14 on the −X direction side (one side) and directly above the dividing line 16 . Next, the lower end of the cutting blade 20 rotating at high speed is lowered from above the plate-shaped object 10 of the remaining size to halfway in the thickness direction of the holding member 19 to cut into the entire thickness direction of the plate-shaped object 10 of the remaining size. At this time, on the starting side (-X direction side) of the cutting feed, the cutting blade 20 cuts in from the inner side of the outer edge of the remaining area 14 (the remaining size plate 10), and at the cutting position - The non-cut portion 25 in which the cut groove 26 is not formed remains on the X direction side.

In the state of maintaining the height position where the cutting blade 20 cuts in, by cutting and feeding the remaining size plate 10 in the X direction relative to the cutting blade 20, it is cut along the planned dividing line 16 of the product area 12 and forms a cut. Ditch 26. On the end side (+X direction side) of the cutting groove 26, as shown in Figure 4, on the side near the outer edge of the remaining size plate 10, that is, the remaining area on the +X direction side (the other side) 14, the cutting blade 20 is raised to leave the remaining size plate 10. In this way, the dicing groove 26 is formed, and the non-cutting portion 27 where the dicing groove 26 is not formed remains in the remaining region 14 on the end side (+X direction side) of the dicing groove 26 .

When one cutting groove 26 is formed, the cutting blade 20 will be fed in the indexing direction (+Y direction) corresponding to the interval of the planned dividing line 16, and the cutting blade 20 will be aligned to the adjacent planned dividing line 16 . The cutting feeding and indexing feeding are repeated in sequence to sequentially cut and form a plurality of cutting grooves 26 on the plate 10 of remaining size. After the product region cutting step is completed, as shown in FIG. 5 , the remaining regions 14 on both sides in the X direction are connected to the workpiece W which will be described later as a strip sheet to form an integral body.

After the product area cutting step is carried out, as shown in FIG. 6 , the segmentation step is carried out. In the dividing step, the remaining size plate 10 is positioned so that the extending direction (second direction) of the boundary positions 30, 31 between the product region 12 and the remaining region 14 becomes the cutting feeding direction (X direction). Next, after the cutting blade 20 is positioned outside the outer edge of the -X direction side of the remaining size plate 10, the cutting blade 20 is lowered, and the cutting blade 20 is positioned so that the holding member 19 can be cut into a predetermined depth. height position. After this positioning, the remaining size plate 10 is cut and fed in the X direction relative to the cutting blade 20 rotating at high speed, so as to cut off at the junction position 30 on one side and divide the remaining size plate 10 in the Y direction for two.

Thereafter, the cutting blade 20 is fed in the index feeding direction (+Y direction) corresponding to the interval between the two boundary positions 30 and 31 , and the cutting blade 20 is aligned to the non-cut boundary position 31 . Then, in the same manner as above, the uncut boundary position 31 is cut to divide the plate-shaped object 10 with an excess size. Thereby, the remaining area 14 can be removed from the product area 12, and as shown in FIG. 7, it can be divided into each work W which becomes a strip-shaped piece.

In addition, in the conventional processing method, in the cutting of the planned division line of the plate-shaped object, it is carried out in such a way that the cutting blade is cut from the outer edge of the -X direction of the plate-shaped object from the outer side of the -X direction when the above-mentioned remaining area is not formed. Cut in and pull out from the outer edge of the plate in the +X direction. Therefore, as shown in FIG. 8, when the plate-like object 100 is a composite material, and compared with the middle metal layer 100a, the resin layers 100b on both sides in the thickness direction are softer and the overall rigidity of the plate-like object 100 is lower, resulting in The workpiece W0 that becomes a strip during the cutting process falls or tilts. As a result, there is a problem that the workpiece W0 is not a rectangle but a trapezoid or a parallelogram when viewed from the first direction side as enlargedly shown in FIG. 8 , thereby reducing machining accuracy.

In this regard, in the processing method of this embodiment, since the remaining region 14 is formed and the non-cutting portions 25, 27 remain on both ends of the cutting groove 26, the following situations can be limited: During the implementation of the product region cutting step The portion to be the workpiece W between adjacent dicing grooves 26 falls or inclines. In this way, even if the rigidity of the plate-shaped object 10 of the remaining size is lowered due to the soft resin layer 10b, etc., it is still possible to remove the remaining area 14 in the dividing step, and then separate the pieces of the workpiece W into strip-shaped pieces one by one. The end faces on both sides in the first direction are formed in a rectangular shape with good accuracy. As a result, even when the plate-like object 10 with the excess size is formed as a composite material, the machining accuracy of the cut-out workpiece W can be maintained well.

Here, in the above-mentioned conventional processing method, the higher the cutting feed rate in the X direction of the cutting blade, the easier it is for the workpiece W0 to fall. On the other hand, in this embodiment, even if the cutting feed speed in the X direction is high, since the fall of the workpiece W is restricted by the remaining area 14, the cutting feed speed can be increased and the throughput can be improved. . In addition, in the present embodiment, in cutting other than the second boundary position 31 , the fall of the workpiece W is regulated by the remaining area 14 on at least one side. Therefore, if the cutting feed speed is set to a high speed for cutting other than the second border position 31, and the cutting feed speed for cutting at the second border position 31 is set to be relatively slow, then it is possible to While keeping the processing accuracy well, the throughput in cutting the entire plate-like object 10 with excess dimensions is improved.

In addition, in the form of the above-mentioned embodiment, although the cutting mechanism is set as the cutting blade 20, it is not limited to this structure. The processing mechanism only needs to be able to form the cutting groove 26 and cut at the boundary positions 30 and 31 similarly to the embodiment, and may also be configured to perform processing by, for example, laser ablation.

In addition, the excess size plate 10 is not limited to the above-mentioned composite material, and various plate-shaped objects such as other composite materials or inorganic material substrates may be used. Various substrates such as sapphire, ceramics, and glass can also be used as the inorganic material substrate. The inorganic material substrate may or may not be formed with elements. In addition, green ceramics and piezoelectric materials can also be used as the plate-shaped object.

In addition, the embodiments of the present invention are not limited to the above-mentioned embodiments, and various changes, substitutions, and deformations can be made without departing from the scope of the technical idea of the present invention. In addition, if the technical idea of the present invention can be realized in other ways through technological progress or other derived technologies, this method can also be used for implementation. Therefore, the scope of claims covers all the embodiments that can be included in the scope of the technical idea of the present invention. Industrial availability

As described above, the present invention is useful in a processing method for dividing a plate-shaped object formed of a composite material having low rigidity due to a soft layer or the like into strip-shaped pieces.
