[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-described circumstances, and has as its object to provide a suction jig and a method of transporting an object to be conveyed without leaving any suction marks. Make it an issue.

[0007]

According to a first aspect of the present invention, there is provided a suction jig for sucking an object to be conveyed by suctioning air, wherein the jig contacts the object in a plane and adsorbs the object. Characterized in that it is provided with a suction member that performs

Next, the operation and effect of the suction jig according to the first aspect will be described.

In the conventional suction jig, since the suction surface is formed in a curved shape, there is a problem that a convex suction mark remains on the transported object when the transported object is sucked.

Here, since the object to be conveyed is in contact with the suction member in a plane, the adsorbed portion of the object to be conveyed does not have a convex shape as in the related art.

As described above, in the suction jig of the present invention, even if the object to be transported is thin, the flatness of the object to be transported can be ensured at the time of suction, so that a convex suction mark is left on the object to be transported. Can be transported.

According to a second aspect of the present invention, there is provided a suction jig having an air suction hole, a holding member for holding the suction member, wherein the suction member has a flat plate formed with an opening communicating with the air suction hole. A porous member that covers the flat plate and contacts the object to be transported in a plane, and a contact member provided on an outer peripheral portion of the porous member and closely adheres to the object to be transported. And

Next, the operation and effect of the suction jig according to the second aspect will be described.

In order to adsorb an object to be conveyed to the adsorbing member,
A hole communicating with the air suction hole formed in the holding member needs to be provided in the suction member. However, if a large hole is provided in a member that is in direct contact with the object to be conveyed, the suction portion of the object to be conveyed is sucked into the hole due to the suction force at the time of suction and becomes convex, leaving a suction mark.

Here, the flat plate provided with an opening communicating with the air suction hole of the holding member is covered with a porous member, and the object to be conveyed is adsorbed on the porous member, so that the hole of the porous member is formed as a flat plate. Since it is much smaller than the opening, it is possible to prevent the suction portion of the transported object from being sucked into the hole of the porous member. As a result, it is possible to prevent the adsorption mark from being left on the transported object.

Further, since the contact member comes into close contact with the object to be conveyed during suction, a gap between the object to be conveyed and the suction jig can be eliminated, and air leakage can be prevented.

According to a third aspect of the present invention, in the suction jig, the holding member is formed with a concave portion forming a space between the holding member and the flat plate.

Next, the operation and effect of the suction jig according to the third aspect will be described.

Since the holding member is provided with a concave portion to form a space between the holding member and the opening member, it is possible to adsorb the conveyed object over a wider area of the porous member. Thus, the transported object can be reliably sucked and transported.

According to a fourth aspect of the present invention, in the suction jig, a support member that supports the flat plate and prevents the flat plate from bending when the load is sucked is formed in the concave portion of the holding member. And

Next, the function and effect of the suction jig according to claim 4 will be described.

Since the supporting member for supporting the flat plate is formed in the concave portion of the holding member, the flat plate can be prevented from bending toward the holding member due to the suction force at the time of suction. Thereby, the flatness of the flat plate and the porous member can be ensured, and the flatness of the transferred object can be ensured.

[0023] In the suction jig according to the fifth aspect, the air suction hole is a screw hole.

Next, the operation and effect of the suction jig according to the fifth aspect will be described.

By using a screw hole for the air suction hole, for example, a jig for transporting the suction jig can be connected by a screw or the like. This allows the air suction hole to have not only an air suction function but also a connection function, so that the suction jig can be easily moved to another location. As a result, the transported object can be transported by suction.

According to a sixth aspect of the present invention, there is provided a method of transporting an object, wherein the object is attracted and transported by using the suction jig according to any one of the first to fifth aspects.

Next, the operation and effect of the method for transporting an object to be transported according to the sixth aspect will be described.

By suctioning and transporting the transported object using the suction jig according to any one of claims 1 to 5, it is possible to prevent a suction mark from remaining on the transported object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A suction jig according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the suction jig 10
Has a square suction jig body 12.

A square concave portion 14 is formed on one surface of the suction jig body 12. At the outer periphery of the concave portion 14, an attachment groove 16 to which a punching metal plate 18 described later is attached is formed. As shown in FIGS. 3 to 5, the depth of the mounting groove 16 is set to be substantially the same as the thickness of the punched metal plate 18.

A seal member 22 is mounted on the outer periphery of the mounting groove 16. As shown in FIGS. 3 to 5, the thickness of the sealing member 22 is set to be substantially the same as the thickness of the porous plate 20. For this reason, the sealing member 22
Has a function to make one surface of the suction jig main body 12 flush and to adhere to the work 24 at the time of suction of the work 24 (see FIG. 6) to prevent air leakage.

The seal member 22 is made of a member obtained by stretching a member formed by compacting a powder made of polytetrafluoroethylene (trade name commercially available from Japan Gore-Tex Corporation). "Goretex" is equivalent to this.)

On the other hand, the substantially square center of the bottom 26 of the suction jig main body 12, which forms a part of the concave portion 14, is provided.
8 are formed. The tip of the support frame 28 reaches the bottom of the mounting groove 16, and the support frame 28 contacts and supports the punched metal plate 18. For this reason,
The support frame 28 has a function of preventing the punching metal plate 18 and the porous plate 20 from bending toward the concave portion 14 during air suction.

Since the support frame 28 is formed substantially at the center of the concave portion 14, the center portion of the punching metal plate 18 having a relatively large bending can be supported, and the bending of the punching metal plate 18 can be effectively prevented.

The support frame 28 is not limited to the square shape shown in FIG. 1, but may be a projection or any other shape as long as it comes into contact with the punched metal plate 18. Further, the number of the support frames 28 is not particularly limited.
One shown in FIG. 1 or two or more provided ones may be used.

A plurality of air suction holes 30 are formed in the bottom 26 of the suction jig body 12. The air suction hole 30 penetrates through the bottom 26 and is formed as a screw hole.

That is, the air suction hole 30 not only has a function as a passage for passing air from the inside of the suction jig main body 12 to the outside, but also has a connection function for connecting a fixing member 40 composed of a bolt 36, a nut 38 and the like. Have. For this reason, as shown in FIG. 6, a tube 32 connected to a vacuum source such as a vacuum suction pump (not shown) is inserted into the air suction hole 30 through the fixing member 40 having a through hole 34 formed in the center. At this time, a work jig (not shown) for moving the suction jig 10 is also fixed at the same time, so that the work 24 can be conveyed while being sucked.

The air suction holes 30 are randomly formed in the bottom 26, but are preferably formed on both the inside and the outside of the support frame 28 as shown in FIG.

On the other hand, a square punching metal plate 18 is mounted in the mounting groove 16. The punching metal plate 18 is attached with, for example, a special adhesive. Further, a plurality of openings 42 having a relatively large diameter are formed in the punching metal plate 18, and communicate with the air suction holes 30 of the suction jig main body 12 when suctioning air.

The punching metal plate 1 is provided in the mounting groove 16.
When the plate 8 is attached, a porous plate 20 having air permeability is attached with an adhesive or the like so as to cover the surface of the punched metal plate 18.

Here, a hole (not shown) having a diameter much smaller than the opening 42 of the punched metal plate 18 is formed in the porous plate 20 and communicates with the opening 42. The porous plate 20 is preferably a flat plate made of a sponge.

Next, the function and effect of the suction jig 10 will be described.

As shown in FIG. 6, a tube 32 connected to a vacuum suction pump (not shown) is fixed to an air suction hole 30 of the suction jig body 12 by a fixing member 40.

The vacuum suction pump is operated, and the suction jig 10 is operated.
Is brought closer to a relatively thin sheet-like work 24 (for example, a ceramic plate, a film, or the like). Workpiece 2 with suction jig 10
4, the hole 24 of the porous plate 20, the opening 42 of the punching metal plate 18, and the air suction hole 30 of the suction jig body 12 are in communication with each other. Adsorbed.

At this time, since the porous plate 20 is formed in a flat plate shape and the diameter of the hole is formed relatively small, the work 24 comes into contact with the porous plate 20 in a flat surface, and Part of 24 is not sucked into the hole. That is, the flatness of the work 24 is secured during the suction. For this reason, it is possible to prevent suction marks from remaining on the work 24.

Further, at the time of suction, the sealing member 22
4, the air can be prevented from leaking from the gap between the suction jig 10 and the work 24. For this reason, a decrease in the air suction force can be prevented, and the work 24 can be reliably adsorbed to the porous plate 20.

Further, since the concave portion 14 is formed in the suction jig body 12 and a large number of openings 42 are formed in the punching metal plate 18, the work 24 is sucked on the entire surface of the porous plate 20. be able to. As a result, the contact area between the work 24 and the porous plate 20 increases, so that the work 24 can be surely adsorbed without wrinkles or the like.

Here, if the concave portion 14 is formed in the suction jig main body 12, a space is formed between the suction jig main body 12 and the punching metal plate 18, so that the punching metal plate 18 bends toward the concave portion 14 when sucking air. However, since the punching metal plate 18 is supported by the support frame 28 formed in the concave portion 14, the bending of the punching metal plate 18 can be prevented. As a result,
Punching metal plate 18 and porous plate 20
And the flatness of the work 24 can be ensured.

In the present embodiment, the square suction jig 10 has been described. However, the present invention is not limited to this. For example, the curved suction surface 106 of the conventional suction jig 104 shown in FIGS. A suction surface may be made flat by filling a sponge (not shown) inside. Thereby, the workpiece can be brought into flat contact with the workpiece at the time of suction, and it is possible to prevent a suction mark from remaining on the workpiece.
