Description

The present invention relates to a jig for laser processing, and more particularly to a jig for laser processing that can enhance versatility.

A technique is known in which a plate-shaped workpiece is cut by a laser beam to be individualized. Patent Document 1 discloses a jig in which a groove is formed on the surface on which the workpiece is placed along a planned cutting line by a laser beam. According to this jig, the work piece is cut and individualized by sweeping the laser beam along the groove (planned cutting line). In this case, since the laser beam that has passed through the workpiece can be received by the groove, even if the laser beam reaches the bottom surface or the side surface of the groove, the jig is damaged because the beam diameter is widened and the energy density is low. Can be suppressed.

WO2013 / 100149 (paragraphs 0043, 0047)

However, in the above-mentioned conventional technique, since the groove is formed along the planned cutting line by the laser beam (that is, the shape to be individualized), if the shape to be individualized is different, a new jig is used. There was a problem that the versatility was low because it was necessary to manufacture the laser.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a laser machining jig capable of increasing versatility.

In order to achieve this object, the laser processing jig of the present invention holds a work piece to be cut by laser light , and is erected from a base base and the base base and has the work piece on the upper surface.

Since the holding means for holding the column member is provided, the space between the adjacent column members can function as a groove for receiving the laser beam that has passed through the workpiece.

In this case, since the pillar members are configured to be removable from the base, for example, by changing the arrangement of the pillar members or changing the size and shape of the pillar members, the space between the adjacent pillar members can be changed. The space (groove) can correspond to the planned cutting line (that is, the shape to be individualized) by the laser beam. Therefore, even if the shape to be individualized is different, it can be dealt with without manufacturing a new laser processing jig. That is, the versatility can be enhanced.

Even if the pillar member or base base is damaged by the laser light that has passed through the workpiece, it is not necessary to replace the entire laser machining jig, and only the damaged parts (pillar member or base base) should be replaced. Can be done.
Further, a recess is recessed in the upper surface of the column member, the column member is provided with a protective member disposed in the recess and made of an elastic material, and the lower surface of the workpiece placed on the upper surface of the column member is. Since it is in contact with the protective member, it is possible to prevent spatter, dross, and the like generated by cutting the workpiece from adhering to a predetermined region (the region with which the protective member is abutted) on the lower surface of the workpiece. Further, while ensuring the thickness dimension of the protective member and making it easy to adhere to the lower surface of the workpiece, the side surface of the protective member is shielded by the side wall of the concave portion, and spatter, dross, etc. generated by cutting the workpiece, etc. Can be prevented from adhering to the side surface of the protective member.

According to the second aspect of the laser processing jig, in addition to the effect of the laser processing jig according to the first aspect, a plurality of recesses are formed in the base base, and the pillar member is formed on the recesses. It is configured to be removable. Therefore, the position where the pillar member is arranged on the base base can be easily recognized by the position of the recess. This makes it easier to construct a laser machining jig.

According to the laser processing jig according to the third aspect, in addition to the effect of the laser processing jig according to the second aspect, a through hole is formed through the recess and a screw is formed on the lower surface of the pillar member. A fastening hole that can be fastened is formed, and the screw inserted through the through hole of the recess is fastened to the fastening hole of the pillar member, so that the pillar member can be attached to and detached from the base base. The structure to enable it can be simplified and the product cost can be reduced. In addition, the pillar members can be easily replaced.

According to the laser processing jig according to claim 4, in addition to the effect of the laser processing jig according to claim 2 or 3, the holding means includes a holding member on the upper surface for holding the workpiece. , A fastening hole to which a screw can be fastened is formed on the lower surface of the holding member, a through hole is formed through the recess, and a screw inserted through the through hole of the recess is fastened to the fastening hole of the holding member. By doing so, the holding member is configured to be detachable from the base base, so that the arrangement of the holding member (holding position of the workpiece) can be changed according to the size of the workpiece. Therefore, the work piece can be held in an appropriate state.

Further, since the through hole of the recess can be shared by the pillar member and the holding member, it is not necessary to separately provide a configuration for attaching and detaching the holding member to the base base. Therefore, the product cost can be reduced accordingly.

(A) is a top view of the laser processing jig, and (b) is a cross-sectional view of the laser processing jig in the Ib-Ib cross-sectional line. It is sectional drawing of the jig for laser processing at the time of laser processing. It is a figure which showed the cutting path of a work schematically. It is a figure which shows the jig for laser processing which has various pillar members. It is a figure which shows the jig for laser processing which hollowed out the irradiation position of a laser beam.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, the outline of the laser processing jig 1 of the present embodiment will be described with reference to FIG. 1 (a) is a top view of the laser processing jig 1, and FIG. 1 (b) is a cross-sectional view of the laser processing jig 1 in the cross-sectional line of Ib-Ib.

In the laser processing jig 1 in the present embodiment, a stainless steel work 5 (see FIG. 2), which is a workpiece, is placed, and the work 5 is cut by irradiating the laser light L from above the work 5 as desired. It is a jig for obtaining the individualized shape 8 (see FIG. 3). The laser processing jig 1 has a base base 2, a plurality of pillar members 3, and a work fixing tool 4.

The base base 2 is an aluminum plate-shaped member for erection of the pillar member 3 and the work fixture 4, which will be described later. A plurality of through holes 2a (recesses) for screwing the pillar member 3 and the work fixture 4 are formed through the base base 2 at equal intervals in the vertical and horizontal directions. From the position of the through hole 2a, the position where the pillar member 3 and the work fixing tool 4 are arranged on the base base 2 can be easily recognized.

The pillar member 3 and the work fixture 4 arranged on the base base 2 are fixed to the base base 2 by screwing from the through hole 2a with a screw 6. Since the through hole 2a is countersunk for the height of the screw head of the screw 6, the screw head can be embedded in the base base 2 and can be reliably fixed by the screw 6.

In the present embodiment, the size of the base base 2 is exemplified by 120 mm in length and 120 mm in width, and the drilling interval of the through hole 2a is exemplified by 5 mm in both the vertical direction and the horizontal direction. The base base 2 is not limited to aluminum, and a material such as steel that can drill through holes 2a and is less likely to be damaged, melted, or thermally deformed by irradiation with laser light L is appropriately applied. You may.

The pillar member 3 is a pillar member that is erected on the base base 2 and on which the work 5 is placed. The pillar member 3 includes a support member 3a, a recess 3b recessed in the upper surface of the support member 3a, a protective member 3c disposed in the recess 3b, and a pillar member 3 disposed in the lower surface of the support member 3a. It is composed of a fastening hole 3d for fastening to the base base 2.

The support member 3a is a steel columnar member having a shape similar to the individualized shape 8 (see FIG. 3) of the work 5 when viewed from above. The individualized shape 8 of the work 5 in the present embodiment is a shape in which four vertices of the rectangular shape are cut off by an arc, and the shape of the support member 3a viewed from above is formed by a rectangular shape inscribed in the individualized shape 8. Will be done. The work 5 placed on the pillar member 3 is cut by irradiating the space between the adjacent support members 3a with the laser beam L to obtain an individualized shape 8 from the work 5.

Further, the lower surface of the support member 3a is made flat. As a result, the pillar member 3 can be erected vertically with respect to the base base 2. The support member 3a is not limited to steel, and may be configured to appropriately apply a material such as ceramic or aluminum that is less likely to be damaged, melted, or thermally deformed by the laser beam L.

The protective member 3c is a member made of synthetic rubber, which is arranged in the recess 3b and for protecting the work 5 fixed to the laser processing jig 1. The shape of the recess 3b and the protective member 3c in the top view is the same as the shape of the support member 3a in the top view. Further, the size of the recess 3b and the protective member 3c in the top view is smaller than the size of the support member 3a in the top view, and the finely processed portion of the work 5 (specifically, the holes 5a and 5b described later in FIG. 2). It is said to close the. As a result, although details will be described later, since the protective member 3c and the finely processed portion of the work 5 are brought into close contact with each other, spatter S, dross D, etc. (see FIG. 2) that occur when the work 5 is irradiated with the laser beam L (see FIG. 2). ), It is possible to protect the finely processed portion of the work 5 from contamination by the dissolved substance of the work 5.

Further, the height of the protective member 3c is larger than the height (depth) in the side view of the recess 3b, and even if the protective member 3c is elastically deformed when the work 5 is attached to the laser machining jig 1. The height is set so that the work 5 does not come into contact with the support member 3a. Therefore, a part of the side surface of the protective member 3c is shielded by the side wall of the recess 3b. The protective member 3c is not limited to that made of synthetic rubber, and is appropriately applied as long as it has elasticity and is in close contact with the work 5, such as natural rubber, silicon gel, and reusable double-sided tape.

The fastening hole 3d is a screw hole for detachably screwing the pillar member 3 and the base base 2. The pillar member 3 is arranged on the base base 2, and the screw 6 inserted from the through hole 2a is screwed into the fastening hole 3d to fasten the base base 2 and the pillar member 3. As a result, the structure for making the pillar member removable can be simplified, so that the product cost can be reduced and the pillar member 3 can be easily replaced.

The height of the pillar member 3, that is, the height from the lower surface of the support member 3a to the upper surface of the protective member 3c is determined by the laser light L emitted from the work 5 placed on the pillar member 3 to cause the base base 2 to be set. The height is set so as not to be damaged, and 50 mm is exemplified.

The work fixture 4 is a columnar member that is erected on the base base 2 and for fixing the work 5 to the laser processing jig 1, and is a fixing hole (not shown) formed in the work 5. It is erected at the position corresponding to. The work fixture 4 is composed of a support member 4a, a work fixing hole 4b arranged on the upper surface of the support member 4a, and a fastening hole 4c arranged on the lower surface of the support member 4a.

The support member 4a is a columnar member for supporting the work 5 on the base base 2. The upper and lower surfaces of the support member 4a are flat. As a result, the work fixture 4 can be erected vertically with respect to the base base 2, and the work 5 fixed on the support member 4a can be supported in parallel with the base base 2. ..

The work fixing hole 4b is a screw hole for fixing the work 5 placed on the laser processing jig 1 with the mounting screw 7 (see FIG. 2). The work 5 and the work fixing tool 4 are fixed by screwing the mounting screw 7 inserted from the fixing hole of the work 5 into the work fixing hole 4b.

The fastening hole 4c is a screw hole for detachably screwing the work fixing tool 4 and the base base 2. The work fixture 4 is arranged on the base base 2, and the screw 6 is inserted through the through hole 2a and screwed into the fastening hole 4c to fasten the base base 2 and the work fixture 4. As a result, the arrangement of the work fixture 4 and the holding position of the work 5 can be changed according to the size of the work 5, so that the work 5 can be held in an appropriate state.

Further, when the pillar member 3 and the work fixing tool 4 are erected, the through hole 2a of the base base 2 can be shared by the fastening hole 3d of the pillar member 3 and the fastening hole 4c of the work fixing tool 4, so that the work fixing tool 4 can be used. It is not necessary to make a through hole in the hole or prepare a screw 6, and the product cost can be reduced accordingly.

The height of the work fixing tool 4 is such that when the work 5 is fixed by the work fixing tool 4, the protective member 3c of the pillar member 3 and the lower surface of the work 5 come into contact with each other, and the protective member 3c is elastically deformed while the work is deformed. The lower surface of the pillar member 3 is set to a height such that the lower surface does not come into contact with the upper surface of the support member 3a of the pillar member 3, and 48 mm is exemplified. As a result, the work 5 fixed to the laser machining jig 1 by the work fixture 4 is not damaged by the support member 3a, and the lower surface of the work 5 is appropriately protected from spatter S, dross D, and the like. Can be done.

From the above, in the laser processing jig 1 of the present embodiment, the pillar member 3 and the work fixing tool 4 are detachably screwed to the base base 2 according to the position and number of the individualized shapes 8 or the shape of the work 5. By stopping, it is configured as a "mold" for cutting the work 5. Therefore, it is not necessary to create a mold corresponding to the position and number of the individualized shapes 8 or the shape of the work 5, so that the product cost can be reduced. Further, since it is only necessary to screw the column member 3 and the work fixing tool 4 into the through hole 2a, a desired mold can be formed in a short time.

Next, with reference to FIG. 2, a case where the work 5 is cut into the individualized shape 8 by the laser beam using the laser processing jig 1 will be described. FIG. 2 is a cross-sectional view of the laser processing jig 1 during laser processing. As shown in FIG. 2, the pillar member 3 is arranged on the base base 2 at a position corresponding to the individualized shape 8, and the work fixture 4 is arranged at a position corresponding to the fixing hole of the work 5 on the base base 2. Then, the work 5 is placed on the laser processing jig 1 configured by screwing the pillar member 3 and the work fixing tool 4 with screws 6, and the fixing hole of the work 5 and the work fixing tool 4 are placed. The laser processing jig 1 and the work 5 are fixed by screwing and with the mounting screw 7. Then, the laser processing jig 1 and the work 5 are arranged on the stage ST on which the object to be processed is placed in the laser processing machine.

Then, the work 5 is cut by irradiating the space between the adjacent pillar members 3 with the laser light L from the processing head H on the laser processing jig 1 and the work 5. Therefore, the space between the adjacent pillar members 3 can function as a "groove" that receives the laser beam L that has passed through the work 5.

By the way, fine holes 5a and 5b are opened in each of the individualized shapes 8 of the work 5 in the present embodiment. During the cutting process of the work 5, spatter S, dross D, dust and the like generated by irradiating the work 5 with the laser beam L adhere to the work 5. If the spatter S, dross D, and dust adhere to the inside of the holes 5a and 5b, it is difficult to remove them.

Therefore, the pillar member 3 of the laser processing jig 1 in the present embodiment is provided with a protective member 3c, and the protective member 3c is arranged at a position that closes the holes 5a and 5b. Further, when the work 5 is fixed to the laser machining jig 1 by the work fixing tool 4, the lower surface of the work 5 and the protective member 3c are in close contact with each other, and the holes 5a and 5b are closed by the protective member 3c. As a result, it is possible to prevent spatter S, dross D, dust and the like generated by irradiating the work 5 with the laser beam L from adhering to the inside of the holes 5a and 5b.

Further, since the protective member 3c is arranged in the recess 3b, if the heights of the support members 3a are the same, the height (thickness) of the protective member 3c can be increased as compared with the case where the recess 3b is not recessed. It can be secured to a large extent. When the work 5 is fixed to the laser machining jig 1, the work 5 and the support member 3a come close to each other due to the dimensional tolerance and distortion of the work 5 and the individual differences of the support members 3a and 4a, so that the work 5 is attached to the protective member 3c. Excessive pressure may be applied. In such a state, when the recess 3b is not recessed, the height (thickness) of the protective member 3c is small, so that the compressibility of the protective member 3c is high. Therefore, on the contrary, the repulsive force from the protective member 3c to the work 5 becomes large, and the work 5 warps toward the upper surface side. As a result, even if the work 5 is cut into individualized shapes 8 by laser light, the shape after cutting may be far from the desired shape, or repulsive force may occur during processing by laser light. There is a risk that the work 5 will be damaged, such as the individualized shape 8 being accidentally cut.

On the other hand, in the present embodiment, since the protective member 3c is arranged in the recess 3b, it is possible to secure a large height (thickness) of the protective member 3c. As a result, even when the work 5 and the support member 3a come close to each other, the compressibility of the protective member 3c becomes small, so that the work 5 can be prevented from warping toward the upper surface side. That is, the dimensional tolerances and distortions of the work 5 and individual differences of the support members 3a and 4a can be absorbed by the protective member 3c.

Here, even when the recess 3b is not recessed, the height (thickness) of the protective member 3c can be secured by lowering the height of the support member 3a and increasing the height of the protective member 3c. can. However, in such a case, since the protective member 3c is completely exposed to the outside, spatter S, dross D, etc. generated when the laser beam L is irradiated to the work 5 adhere to the protective member 3c, and the protective member There is a risk that 3c will be damaged.

On the other hand, in the present embodiment, since the protective member 3c is arranged in the recess 3b, a part of the side surface of the protective member 3c is shielded by the side wall of the recess 3b. As a result, it is possible to suppress the adhesion of spatter S, dross D, etc. to the protective member 3c, so that deterioration of the protective member 3c can be suppressed.

Next, a method of cutting the work 5 by the laser beam L will be described with reference to FIG. FIG. 3 is a diagram schematically showing a cutting route (planned cutting line) of the work 5. In the present embodiment, the work 5 is cut by irradiating the laser beam L from above the work 5 along the space between the adjacent pillar members 3. At that time, it is possible to completely separate the work 5 for each individualized shape 8, but if the work 5 is completely separated for each individualized shape 8, in a later process (for example, cleaning or painting). Since the separated individualized shapes 8 must be collected and individually processed, the work efficiency is significantly reduced. Therefore, in the present embodiment, the work 5 is not completely separated by providing two or more connection points for one pieced shape 8.

Specifically, at least two cutting paths are provided for one pieced shape 8 to irradiate the laser beam L. In the present embodiment, two cutting paths are provided, the first is a corner portion of the individualized shape 8, and the starting point S1 on the outside of the individualized shape 8 in the work 5 is directed toward the pillar member 3. It is a cutting path L1 along the side surface of the pillar member 3 to the end point E1 on the diagonal side of the start point S1 as it is. The other is adjacent to the end point E1 and runs along the side surface of the pillar member 3 from the outer start point S2 of the individualized shape 8 in the work 5 toward the pillar member 3 and directly to the diagonal end point E2 of the start point S2. It is a cutting path L2. It should be noted that the start point S1 and the end point E2, which are adjacent to each other, and the start point S2 and the end point E2 are set to different positions.

The region formed by the cutting path L1 and the cutting path L2 becomes an individualized shape 8, but it is formed by two connection points between the start point S1 and the end point E2 and between the start point S2 and the end point E1. , The individualized shape 8 remains on the work 5. As a result, each pieced shape 8 is not completely separated from the work 5, so that the work efficiency in the process after the cutting process is improved. In addition, in this embodiment, the connection points are provided at two places for one pieced shape 8, but the connection points are not limited to two places, and may be one place or three or more places. good.

Further, both the starting points S1 and S2 are provided on the outside of the individualized shape 8 in the work 5. The starting points S1 and S2 are set outside the individualized shape 8 in the work 5, because a large amount of spatter S is generated at the start of the output of the laser beam L, especially until the laser beam L penetrates the work 5. However, the spatter S adheres to the work 5. Therefore, by setting the positions of the starting points S1 and S2 to the outside of the individualized shape 8 in the work 5, that is, the position finally separated from each individualized shape 8, the individual individualized shape 8 is finally separated from the individual individualized shape 8. , Adhesion of spatter S can be suppressed.

As described above, the laser processing jig 1 of the present embodiment holds the base base 2, a plurality of pillar members 3 erected from the base base 2, and the work 5 on the base base 2 or the pillar member 3. A work fixing tool 4 is provided. Therefore, the space between the adjacent pillar members 3 can function as a groove for receiving the laser beam L that has passed through the work 5. In this case, since the pillar member 3 is configured to be detachable from the base base 2, for example, by changing the arrangement of the pillar member 3 or changing the size and shape of the pillar member 3, adjacent pillars are formed. The space (groove) between the members 3 can be made to correspond to the individualized shape 8 by the laser beam. Therefore, even if the individualized shapes 8 are different, it can be dealt with without newly manufacturing the laser processing jig 1. That is, the versatility can be enhanced.

Further, even if the pillar member 3 or the base base 2 is damaged by the laser beam L passing through the work 5, it is not necessary to replace the laser processing jig 1, and only the pillar member 3 or the base base 2 can be replaced. can.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and it is easy that various improvements and changes can be made without departing from the spirit of the present invention. It can be inferred from.

The numerical values given in the above embodiment are examples, and it is naturally possible to adopt other numerical values.

In the above embodiment, the laser processing jig 1 is used for laser processing, but the present invention is not limited to this. It may be applied to other machine tools such as NC machine tools that perform cutting and drilling.

In the above embodiment, the column member 3 and the work fixture 4 are screwed to the base base 2, but the present invention is not limited to this. A protrusion is provided on the bottom surface of the pillar member 3 and the work fixing tool 4, and the protrusion is inserted into the through hole 2a of the base base 2, so that the pillar member 3 and the work fixing tool 4 are arranged on the base base 2. good. Further, instead of the through hole 2a of the base base 2, a recess that is not formed through is provided, and the protrusion of the pillar member 3 and the work fixing tool 4 is inserted into the recess to base the pillar member 3 and the work fixing tool 4. It may be configured to be arranged on the table 2. In this case, the cross-sectional shapes of the protrusions, through holes 2a, and recesses are in an unstable state, such as a rectangle or a cross shape, and the pillar member 3 and the work fixing tool 4 arranged on the base base 2 rotate. It is preferable that the shape is not formed.

In the above embodiment, the pillar member 3 has a recess 3b and a protective member 3c, but the present invention is not limited to this. The pillar member 3 may be configured by removing the recess 3b and the protective member 3c. Even in such a case, since the holes 5a and 5b of the work 5 placed on the laser processing jig 1 and the support member 3a of the pillar member 3 are in contact with each other, spatter S and dross are formed in the holes 5a and 5b. It is possible to suppress the invasion of D and the like.

In the above embodiment, the individualized shape 8 of the work 5 is formed by cutting off four vertices of the rectangular shape by an arc, and the shape of the support member 3a viewed from above is formed into a rectangular shape inscribed in the individualized shape 8. It is not always limited to this. The individualized shape 8 of the work 5 may be configured as various shapes such as a triangle. FIG. 4 is a diagram showing a laser processing jig 1 having various pillar members 3. As shown in FIG. 4, as the shape of the pillar member 3, various shapes such as a triangle, a star, a circle, and the like can be applied other than the rectangle. Further, the shapes of the pillar members 3 erected on the laser processing jig 1 do not necessarily have to be the same, and the pillar members 3 having various shapes may be mixed and configured.

In the above embodiment, the heights of the pillar member 3 and the work fixture 4 are configured to be such that the base base 2 is not damaged by the laser beam L emitted from the pillar member 3 and the work fixture 4. I said. In addition to this, or instead of this, the height of the support member 3a of the pillar member 3 and the support member 4a may be lowered, and then the irradiation position of the laser beam L on the base base 2 may be hollowed out. FIG. 5 is a diagram showing a laser processing jig 1 in which the irradiation position of the laser beam L is hollowed out. As shown in FIG. 5, a rectangular groove 2b is provided by hollowing out between the through holes 2a around the vertical position of the pillar member 3 of the base base 2.

The laser beam L irradiated from above the work 5 placed on the laser processing jig 1 passes through the groove 2b. As a result, the area of the base base 2 irradiated with the laser beam L becomes small, and the area of the base base 2 damaged by the laser light L also becomes small, so that deterioration of the base base 2 can be suppressed. Further, when the heights of the support member 3a of the pillar member 3 and the support member 4a are lowered, the manufacturing cost of the support members 3a and 4a is reduced, so that the manufacturing cost of the laser processing jig 1 can also be reduced. The groove 2b is not necessarily limited to being hollowed out in a rectangular shape, and various shapes are appropriately applied depending on the shape of the support member 3a when viewed from above. Further, the groove 2b may be hollowed out along the shapes of the cutting paths L1 and L2 shown in FIG.
