Japanese Unexamined Patent Publication No. 2015-140289

In a device that performs a three-point bending brake on a substrate while mounted on a belt conveyor, the belt conveyor is bent at a location where the three-point bending brake is applied, and there is a possibility that the three-point bending brake of the substrate cannot be properly executed. there was. For example, it is conceivable that the substrates after the brake are in contact with each other due to the bending of the belt conveyor and the substrates after the brake are damaged.

An object of the present invention is to suppress the bending of a member on which the substrate is mounted in cutting (braking) a substrate by a three-point bending brake method.

Hereinafter, a plurality of aspects will be described as a means for solving the problem. These aspects can be arbitrarily combined as needed.

A table according to one aspect of the present invention is a table on which a substrate to be cut (braking) is placed in a three-point bending brake method. The table includes a frame, a mounting member, and a fixing member. The frame has an opening. The mounting member is flexible, and forms a mounting table for mounting the substrate by covering the opening of the frame. The fixing member fixes the end of the mounting member to the frame while pulling the mounting member with a predetermined tensile force.

In the above table, a mounting member serving as a mounting table for mounting a substrate is pulled with a predetermined tensile force while covering the opening of the frame and fixed to the frame. That is, the flexible mounting member has a configuration covering a limited space called an opening provided in the frame. Accordingly, it is possible to suppress the bending of the placement member in the area of the placement table on which the substrate is placed.

The frame may be circular. Due to this, it is possible to evenly apply a tensile force to the mounting member.

A brake device according to another aspect of the present invention includes a brake unit and a table. The brake part brakes the board with a three-point bending brake. The table mounts the substrate to be braked by the brake unit.

A table provided in the brake device includes a frame, a mounting member, and a fixing member. The frame has an opening. The placing member is flexible, and forms a placing table for placing the substrate by covering the opening of the frame. The fixing member fixes the end of the mounting member to the frame while pulling the mounting member with a predetermined tensile force.

In the table provided in the above-described brake device, a mounting member serving as a mounting table for mounting a substrate is pulled with a predetermined tensile force while covering the opening of the frame and fixed to the frame. Accordingly, even if the placing member has flexibility, it is possible to suppress the bending of the placing member within a limited space in which the opening provided in the frame is placed, that is, within a limited area in which the substrate is placed. As a result, the brake device can appropriately brake the substrate by the three-point bending brake.

The above-described brake device may further include a support portion. The support part supports the table detachably. Accordingly, the mounting of the substrate on the table can be performed at a place different from the place where the brake device is installed.

The support portion may be capable of adjusting the mounting angle of the table. This makes it possible to break the substrate in any direction.

The bending of the mounting member on which the board to be braked by the three-point bending brake is mounted can be suppressed, and the board mounted on the mounting member can be properly braked by the three-point bending brake.

1. First embodiment

(1) brake system

Hereinafter, a brake device 100 according to a first embodiment will be described with reference to FIGS. 1 and 2. 1 is a top view of a brake device according to a first embodiment. Fig. 2 is a cross-sectional view taken along line A-A of the brake device of Fig. 1 according to the first embodiment. In Figs. 1 and 2, the height direction is indicated by an arrow in the Z direction. In addition, the horizontal direction perpendicular to the height direction (Z direction) is indicated by an arrow as the X direction.

The brake device 100 according to the first embodiment is a device that brakes the substrate S by a "three-point bending brake". Specifically, the brake device 100 forms the scribe lines SL1 and SL2 while supporting the substrate S with two points interposed between the scribe lines SL1 and SL2 (FIG. 4) formed on the substrate S. The substrate S is cut (brake) by pressing the portion near the side opposite to the side on which the scribe lines SL1 and SL2 of the substrate S are formed. The brake device 100 brakes the brake substrate S in a state in which it is placed on the flexible mounting member 33.

The brake device 100 includes a brake part 1, a table 3, and a support part 5. As shown in FIG. 2, in the brake device 100 according to the first embodiment, a pair of brake units 1 is provided in the Z direction with the table 3 interposed therebetween. On the other hand, a pair of brake units 1 are installed to face each other in the X direction.

The brake unit 1 brakes the substrate S placed on the table 3 (placement member 33) with a three-point bending brake. Specifically, the brake unit 1 has a support member 11 and a pressing member 13.

The support member 11 is, for example, an L-shaped member, and a pair is provided at predetermined intervals in the X direction. Further, the support member 11 is moved in the Z direction by a driving mechanism such as a fluid cylinder (not shown), for example. When the support member 11 moves in the Z direction and approaches the substrate S, the L-shaped portion of the support member 11 extending in the X direction (referred to as the support portion 11a) is on the substrate S. The substrate S can be supported by the support portion 11a by contacting.

The pressing member 13 is, for example, a long plate-shaped brake bar, and is provided between the pair of support members 11. The pressing member 13 moves in the Z direction by a driving mechanism such as a fluid cylinder (not shown), for example. That is, the pressing member 13 is movable in the Z direction between the pair of support members 11. The pressing member 13 moves in the Z direction while supporting the substrate S by the support portion 11a of the brake unit 1 on the opposite side with the substrate S interposed therebetween, and is pressed against the substrate S. It is possible to break the substrate S.

The table 3 mounts the substrate S to be braked by the brake unit 1. In the brake device 100 of the present embodiment, the three-point bending brake of the substrate S is performed while the substrate S is mounted on the table 3. The specific configuration of the table 3 capable of a three-point bending brake of the substrate S will be described later in detail.

The support part 5 supports the table 3 in a detachable manner. Specifically, the support portion 5 has a first storage opening O1 capable of accommodating the table 3. As shown in FIG. 2, the support part 5 contacts the flange part 31a (to be described later) of the table 3 on its upper surface, and opens the lower part (placement member 33) of the table 3 to the first storage opening ( The table 3 can be supported by storing it in O1). On the other hand, by separating the table 3 accommodated in the first storage opening O1 from the first storage opening O1, the table 3 can be removed from the support portion 5.

Since the table 3 is detachable from the support part 5, for example, the substrate S can be mounted on the table 3 at a location away from the installation location of the brake device 100.

1 and 2, the brake device 100 includes a moving table 7. The moving platform 7 supports the support 5. The moving table 7 is provided with a second storage opening O2 corresponding to the first storage opening O1 of the support portion 5, and a guide rail 71 is provided along the second storage opening O2. The guide rail 71 is fitted with a concave portion 51 provided along the first storage opening O1 from the lower portion of the support portion 5. Thereby, the support part 5 is supported by the moving table 7 in a state rotatable around the Z-axis.

Further, a rotation driving unit 73 is provided on the moving table 7. The rotation drive part 73 is a device that rotates the support part 5 around the Z-axis, and has, for example, a first gear 73a and a drive part 73b. The first gear 73a meshes with the second gear 53 installed on the lower side of the support 5. The driving unit 73b rotates the first gear 73a. When this rotation drive part 73 rotates the support part 5 around the Z-axis, the support part 5 rotates the table 3 accommodated in the 1st accommodating opening O1 about the Z-axis. Thereby, the support part 5 can adjust the installation angle of the table 3.

Since the mounting angle of the table 3 is adjustable, the substrate S can be braked in any direction.

Further, the moving platform 7 is movable in the X direction along a pair of rails 9 arranged at predetermined intervals. Accordingly, the moving table 7 can move the substrate S placed on the table 3 in the X direction with respect to the brake unit 1.

(2) table

Next, the configuration of the table 3 on which the substrate S to be braked by a three-point bending brake is placed will be described with reference to FIG. 3. 3 is a cross-sectional view of a table according to the first embodiment. In the table 3, the substrate S has flexibility and is placed on the mounting member 33 in a pulled state by a predetermined tensile force.

Specifically, the table 3 has a frame 31, a mounting member 33, and a fixing member 35. The frame 31 is a ring-shaped (circular) member having an opening (O3). By making the frame 31 in a ring shape, when the mounting member 33 is fixed to the frame 31, a tensile force can be applied to the mounting member 33 evenly. The frame 31 has an L having a flange portion 31a that contacts the upper surface of the support portion 5 when the table 3 is supported by the support portion 5, and a fixing portion 31b to which the mounting member 33 is fixed. It is a ruler-shaped member.

The mounting member 33 is, for example, a sheet-like member made of a flexible material. The mounting member 33 is, for example, a sheet made of urethane rubber. The mounting member 33 covers the opening O3 in a state pulled by a predetermined tensile force by the fixing member 35. The portion of the mounting member 33 covering the opening O3 forms a mounting table on which the substrate S is mounted.

Moreover, the surface of the mounting member 33 has an uneven shape. Since the uneven shape on the surface of the placing member 33 can reduce the contact area between the placing member 33 and the substrate S, it is possible to move the substrate S on the placing member 33 when the 3-point bending brake is executed. You can do it easily.

Further, when the mounting member 33 is made of a material having a relatively small coefficient of friction with respect to contact with the substrate S, it may not have an uneven shape on its surface.

The fixing member 35 is a member that fixes the end of the mounting member 33 to the frame 31 in a state in which the mounting member 33 is pulled with a predetermined tensile force. The fixing member 35 is, for example, a nail such as a rivet, a bolt nut, a turnbuckle, or the like. When the fixing member 35 is a turnbuckle, the bending state of the placing member 33 on the placing table may be adjusted by adjusting the tensile force of the placing member 33.

In the table 3 having the above configuration, the mounting member 33 covers a limited space (a short distance) called an opening O3 provided in the frame 31. Accordingly, even if the mounting member 33 has flexibility, it is possible to suppress the bending of the mounting member 33 in the region of the mounting table on which the substrate S is mounted.

(3) 3-point bending brake operation of the board

Hereinafter, an operation of performing a three-point bending brake on the substrate S placed on the table 3 using the brake device 100 according to the first embodiment will be described with reference to FIGS. 4A to 4F. 4A to 4F are diagrams schematically showing an example of a three-point bending brake operation of the substrate by the brake device according to the first embodiment. In Figs. 4A to 4F, when the mounting member 33 is used as a reference, the side where the substrate S is present in the Z direction is defined as the upward direction, and the side where the opening O3 is present is defined as the downward direction.

In the following description, the substrate S is a substrate obtained by bonding the first substrate S1 and the second substrate S2. Further, in the following description, the substrate S along the first scribe line SL1 provided on the first substrate S1 and the second scribe line SL2 provided on the second substrate S2 using the brake device 100. ) Will be described.

First, a first scribe line SL1 is formed on the first substrate S1 of the substrate S to be braked, and a second scribe line SL2 is formed on the second substrate S2, and the substrate S ) Is placed on the placing member 33 of the table 3. Here, as shown in Fig. 4A, it is assumed that the substrate S is placed so that the second substrate S2 faces downward.

Next, as shown in FIG. 4A, a pair of support members 11 provided on the side of the second substrate S2, that is, below, are brought close to the mounting member 33, and the pair of support members 11 is used as the substrate ( S) is supported on the second substrate S2 side (lower side). At this time, the second scribe line SL2 exists between the pair of support members 11.

Thereafter, as shown in FIG. 4B, the upper pressing member 13 is brought close to the substrate S while supporting the substrate S on the lower support member 11 from the lower side, and the upper pressing member 13 ) Is brought into contact with the first substrate S1. By moving the pressing member 13 further downward while in contact with the first substrate S1, the second substrate S2 is braked along the second scribe line SL2 as shown in FIG. 4C.

After breaking the second substrate S2, as shown in FIG. 4D, a pair of support members 11 installed on the side of the first substrate S1, that is, above, are brought close to the first substrate S1, and the pair of The substrate S is supported on the support member 11 from the first substrate S1 side (upper side). At this time, the first scribe line SL1 exists between the pair of support members 11.

After that, as shown in Fig. 4E, the lower pressing member 13 is brought close to the substrate S while the substrate S is supported by the upper support member 11 from the upper side, and the lower pressing member 13 is Is brought into contact with the mounting member (33). By moving the pressing member 13 further upward in a state in which it is in contact with the mounting member 33, the first substrate S1 is braked along the first scribe line SL1 as shown in FIG. 4F.

As described above, since bending of the placing member 33 is suppressed in the table 3, when the substrate S is pressed by the pressing member 13 to break the substrate S, the placing member 33 ) Does not bend greatly.

As a result, movement of the substrate after the brake due to the bending of the placing member 33 is suppressed, and it is possible to suppress the two substrates after the brake from colliding and being damaged.
