Definitions
- the present invention relates to a work connection device for connecting multiple workpieces.
- Patent Document 1 describes a laser processing device 1 that laser welds a part P to a workpiece W placed on a workbench 4 (see paragraphs "0030" to "0032" and Figure 1, etc.).
- the laser processing device 1 described in Patent Document 1 uses a pressing portion 26 to press the top surface of a workpiece W and the top surface of a part P placed on a worktable 4, and in this state, irradiates laser light L from a laser processing head 5 to connect the workpiece W and the part P (see paragraphs "0054" to "0057” and Figure 10, etc.).
- the laser processing device 1 (hereinafter referred to as the "workpiece connecting device") does not cause any problems in connection when the workpiece W is planar and the work table 4 is also planar, but when the workpiece W has a complex shape such as a curved or bent shape, it is very difficult to connect the part P to any point on the workpiece W having a complex shape.
- the present invention has been made in response to the above-mentioned problems with the conventional technology, and aims to provide a work connection device that can quickly connect components to a workpiece, even if the workpiece has a complex shape, and further, a work connection device that improves the appearance quality of the workpiece after connection.
- the first aspect of the present invention is a work connection device that biases a second work against a surface of a first work to connect the second work to the surface of the first work, the work connection device being characterized by comprising an articulated robot and a support body that is connected to the tip of the articulated robot and can abut against the back surface of the first work.
- the second aspect of the present invention is characterized in that in the work connection device of the first aspect, the support body is provided with a plurality of first plates arranged so that their normals are directed in a plurality of directions.
- the third aspect of the present invention is characterized in that in the workpiece connecting device of the second aspect, a polyhedron is connected to the tip of the articulated robot, and each of the multiple first plates is separately connected to one of the faces that constitute the polyhedron.
- the fourth aspect of the present invention is characterized in that in the work connection device of the third aspect, the polyhedron has an open surface and an internal cavity, and each of the plurality of first plates is clamped to the polyhedron by a fastener from the cavity and is separately connected to one of the surfaces that constitute the polyhedron.
- the fifth aspect of the present invention is characterized in that in the work connection device of any of the second to fourth aspects, the first plate has a structure in which the center portion protrudes.
- a sixth aspect of the present invention is a work connection device that urges a second work against a surface of a first work to connect the second work to the surface of the first work, comprising a moving body and at least one second plate that is arranged on the moving body and can abut against the back surface of the first work and has a normal that can be changed to a plurality of directions, and is characterized in that the direction of the normal of at least one of the second plates can be fixed when the second plate abuts against the back surface of the first work.
- the seventh aspect of the present invention is characterized in that in the work connection device of the sixth aspect, the second plate has a structure in which the center portion protrudes.
- the support body is provided with a plurality of first plates arranged so that their normals point in a plurality of directions. Therefore, in addition to the effect of the work connection device of the first aspect, even if the first work has a complex shape, an appropriate first plate can be selected and abutted against the back surface of the first work, and thus the second work can be efficiently connected to the front surface of the first work. On the other hand, even if one first plate becomes unusable, the other first plate can be used, thereby improving the durability of the device.
- a polyhedron is connected to the tip of the articulated robot, and each of the multiple first plates is separately connected to one face that constitutes the polyhedron, so that in addition to the effect of the workpiece connecting device of the second aspect, it is possible to easily create a structure in which an appropriate first plate can be selected and abutted against a first workpiece of a complex shape.
- the polyhedron has an open surface and an internal cavity, and each of the multiple first plates is clamped to the polyhedron by fasteners from the cavity and is separately connected to one of the surfaces that make up the polyhedron.
- the first plate has a structure with a protruding center, so that in addition to the effect of the work connection device of any of the second to fourth aspects, it is possible to prevent distortion occurring on the surface of the first work and/or the surface of the second work, thereby improving the appearance quality.
- the second plate has a structure in which the center protrudes, so that in addition to the effect of the work connection device of the sixth aspect, it is possible to prevent distortion occurring on the surface of the first work and/or the surface of the second work, thereby improving the appearance quality.

- the second holding portion 7c configured as described above, like the second holding portion 7a of the first embodiment, first lowers the second base portion 13, the second swivel fixing solenoid valve 26, the expansion/contraction portion 17, and the second holding suction portion 46 in the -Y direction by the second holding cylinder 42, and then fixes the expansion rod 15 in the lowered position with the compression spring compressed by the second up/down fixing solenoid valve 28.
- the second pressing part 7c is moved below the connection position using the second pressing slide motor 22, and then the second up-down fixing solenoid valve 28 is released, and the second base 13, the second swivel fixing solenoid valve 26, the expansion/contraction part 17, the second pressing suction part 46 and the protrusion 49 are raised in the +Y direction by the force of the compression spring, and the second pressing suction part 46 and the protrusion 49 are brought into contact with the back surface of the first workpiece W1.
- the second pressing portion 7c is configured to be movable in the +X direction or the -X direction on the right mounting table 88b fixed to the mounting table 88 by using a second pressing slide motor 22 arranged near the right mounting table 88b and a ball screw arranged inside the right mounting table 88b.
- the rotational force of a motor gear fixed to the motor shaft of the second pressing slide motor 22 is transmitted to the ball screw.
- the second clamping portion 7c can also be used in place of the third clamping portion 7b.
- the workpiece connecting device 101 of this embodiment is intended for connecting the second workpiece W2 to the surface of the first workpiece W1 by pressing the second workpiece W2 against the surface of the first workpiece W1, and is particularly equipped with one movable second pressing suction part 46 that can contact the back surface of the first workpiece W1 and whose normal can be changed in multiple directions. Since the direction of the normal of the second pressing suction part 46 can be fixed when it contacts the back surface of the first workpiece W1, the second pressing suction part 46 can be appropriately contacted with the back surface of the first workpiece W1 even if the first workpiece W1 has a complex shape, and thus the second workpiece W2 can be quickly connected to the surface of the first workpiece W1.
- the second pressing suction portion 46 has a protruding portion 49 with a protruding central portion, which prevents distortion from occurring on the surface of the first workpiece W1 and/or the surface of the second workpiece W2 during welding, thereby improving the appearance quality of the entire workpiece including the first workpiece W1 and the second workpiece W2.
- the present invention is not limited to this, and can be applied to any connection, including crimping, pressure welding, etc., as long as the second workpiece W2 is connected to the first workpiece by pressing it against it.
- the support body is described as a 14-sided polyhedron, and the shape of the first plate constituting the polyhedron is described as being approximately triangular, but this is not limited thereto, and the polyhedron may be a polyhedron with two or more sides, and may be partially curved. Furthermore, the shape of the first plate constituting the polyhedron may be any shape.
- the shape of the first plates that make up the polyhedron is a uniform shape, and it is better for the polyhedron to be made up of first plates with that uniform shape.
- the support is described as having a hemispherical shape, but this is not limited thereto, and may be, for example, a shape in which two or more planes are folded into a V shape.
- the second holding portion 7a and the third holding portion 7b have been described as moving in a linear direction, but this is not limited thereto, and the direction of movement can be changed as appropriate depending on the specifications of the work connection device.
