Description

The present invention relates to a terminal positioning device and a terminal positioning method.

Conventionally, a terminal positioning method for positioning a terminal such as a power line of a motor is known (for example, see Patent Document 1).

Patent Document 1 describes that one end of a power line is connected to one end of a stator coil of a stator by welding. Further, a terminal is connected to the other end of the power line. Here, in order to accurately connect the power line to the stator coil, it is necessary to accurately position the terminal in the height direction. Therefore, although it is not specified in Patent Document 1, it is considered that the terminals of the power line are positioned in the height direction.

JP2019-92248A

Although not specified in Patent Document 1, in order to position the terminal in the height direction, it is conceivable to detect the height position of the terminal with a camera and perform position correction, for example. In this case, it is conceivable that the positioning work becomes complicated due to the need to use a camera, and the time required for the positioning work becomes longer due to the time required to read the camera. Therefore, there is a need for a terminal positioning device and a terminal positioning method that can position the terminal in the height direction without using a camera.

The terminal is moved upward along the slope by sandwiching the terminal between the slopes of each of the pair of clamp members and then moving the pair of clamp members closer to each other. The terminal is configured to be positioned at a predetermined height reference position by causing the terminal to move and abut against the height positioning portion. Note that the term "tapered" includes both a case where the sloped part is provided in a straight line and a case where the sloped part has a curved shape instead of a straight line.

As described above, in the terminal positioning device according to the first aspect of the present invention, the terminal is sandwiched between the inclined portions of the pair of clamp members, and the pair of clamp members are further brought closer to each other, thereby positioning the terminal on the inclined portion. The terminal is configured to be mechanically positioned at a predetermined height reference position by moving the terminal upward along the height positioning portion and abutting the height positioning portion. As a result, the terminal is mechanically positioned at a predetermined height reference position by moving the terminal along the inclined portion of the pair of clamp members and bringing the terminal into contact with the height positioning portion, so that the terminal can be mechanically positioned at a predetermined height reference position. There is no need to detect the position of the terminal in the height direction and perform position correction. Therefore, the terminal can be positioned in the height direction without using a camera. In addition, the terminal can be positioned in the height direction simply by bringing the pair of clamp members close to each other, which simplifies the positioning work compared to manually positioning the terminal in the height direction. can.

Further, the terminal positioning method according to the second aspect of the present invention includes inclined portions that move toward and away from each other in the first direction in the horizontal direction, and that are provided so as to extend at an angle with respect to the height direction. a pair of clamps, each included in the clamp, and provided so that the gap between the mutually inclined parts is formed in a tapered shape tapering downward when viewed from a second horizontal direction perpendicular to the first direction. a pinching step in which the terminals of the conductor are sandwiched in the first direction by the inclined portions of each of the pair of clamp members by bringing the members closer to each other; and after the pinching step, the pair of clamp members are further brought closer to each other while sandwiching the terminals; By this, the terminal is moved upward along the inclined part, and is provided at a predetermined height reference position above the lower end of the inclined part of each of the pair of clamp members, and the terminal is moved in the height direction of the terminal. and a height positioning step of positioning the terminal at a predetermined height reference position in the height direction by bringing the terminal into contact with a height positioning part that performs positioning.

The terminal positioning method according to the second aspect of the present invention, as described above, moves the terminal upward along the slope and increases the height by moving the pair of clamp members closer to each other while sandwiching the terminal. The method includes a height positioning step of positioning the terminal at a predetermined height reference position in the height direction by bringing the terminal into contact with the positioning portion. As a result, the terminal is mechanically positioned at a predetermined height reference position by moving the terminal along the inclined portion of the pair of clamp members and bringing the terminal into contact with the height positioning portion, so that the terminal can be mechanically positioned at a predetermined height reference position. There is no need to detect the position of the terminal in the height direction and perform position correction. Therefore, it is possible to provide a terminal positioning method that allows positioning of the terminal in the height direction without using a camera. In addition, the terminal can be positioned in the height direction simply by bringing the pair of clamp members close to each other, which simplifies the positioning work compared to manually positioning the terminal in the height direction. A possible terminal positioning method can be provided.

Embodiments of the present invention will be described below based on the drawings.

A terminal positioning device 100 and a terminal positioning method according to this embodiment will be described with reference to FIGS. 1 to 7.

In this specification, the X direction is the direction in which the clamp member 3, which will be described later, moves in the horizontal direction. Further, the Y direction is a direction in the horizontal direction orthogonal to the X direction. Note that the Z direction is the height direction. Note that the X direction is an example of a "first direction" in the claims. Further, the Y direction is an example of a "second direction" in the claims. Further, the Z direction is an example of the "height direction" in the claims.

As shown in FIG. 1, the terminal positioning device 100 has a terminal 200 of a power line 201 housed in a tray 101 that is conveyed by a belt conveyor or the like to a predetermined position in the movable range 100a of the terminal positioning device 100 (see FIG. 3). It is configured to take out. Note that the power line 201 is an example of a "conductor" and "wiring" in the claims.

Next, the terminal positioning device 100 transports the terminal 200 taken out from the tray 101 to the power line setting section 102 provided at a predetermined position in the movable range 100a of the terminal positioning device 100. In the power line setting section 102, the power line 201 connected to the terminal 200 is attached to a welding jig (not shown). Next, the terminal 200 and the power line 201 attached to the jig are moved to the power line welding part 103 by a robot arm or the like separate from the terminal positioning device 100. In the power line welding section 103, an end 201a of the power line 201 on the opposite side from the terminal 200 is welded to a lead wire (not shown) of the stator 104.

As shown in FIG. 2, the tray 101 is provided with a plurality of recesses 101a in which terminals 200 and power lines 201 are accommodated. Note that the tray 101 is made of foamed resin as a cushioning material. Therefore, the positions in the Z direction of the terminals 200 and the power lines 201 accommodated in each of the plurality of recesses 101a vary by a predetermined amount (for example, about ±2 mm with respect to the set value).

Next, the configuration of the terminal positioning device 100 and the terminal positioning method using the terminal positioning device 100 will be described.

(Terminal positioning device)
As shown in FIG. 3, the terminal positioning device 100 includes a robot hand connecting section 1 connected to a robot hand 105. As shown in FIG. Note that the robot hand 105 is configured to move a pair of clamp members 3 and pin members 5, which will be described later, in the Z direction (Z1 direction and Z2 direction).

Further, the terminal positioning device 100 includes an actuator 2. The actuator 2 is configured to move a pair of clamp members 3, which will be described later, in the X direction. Specifically, the actuator 2 is configured to move the pair of clamp members 3 by the same distance in opposite directions in the X direction. Note that the actuator 2 is, for example, an air-driven actuator.

The terminal positioning device 100 includes a pair of clamp members 3. The pair of clamp members 3 move toward and away from each other in the horizontal X direction. Moreover, each of the pair of clamp members 3 is provided so as to extend in the Z direction. Further, each of the pair of clamp members 3 is made of iron, for example. Note that the terminal 200 is made of copper, for example. Further, the terminal 200 includes a flat plate-shaped portion 200a (see FIG. 4) that is provided to extend within the horizontal plane (in the XY plane).

Each of the pair of clamp members 3 includes an inclined portion 30 provided to extend at an angle with respect to the height direction. The pair of clamp members 3 are formed in such a manner that the gap S between the inclined portions 30 is formed in a tapered shape that tapers downward (Z2 side) when viewed from the Y direction, which is a horizontal direction perpendicular to the X direction. It is provided. Specifically, the inclined portion 30 of the clamp member 3 on the X1 side is provided so as to be inclined toward the X1 side toward the Z1 side. Further, the inclined portion 30 of the clamp member 3 on the X2 side is provided so as to be inclined toward the X2 side toward the Z1 side.

As shown in FIG. 4, the lower parts 3a provided on each of the pair of clamp members 3 and including the lower end 31 of the inclined part 30 are positioned relative to each other when viewed from the X direction so that they overlap each other in the Y direction. They are staggered and arranged.

Thereby, the pair of clamp members 3 can be brought closer to each other in the X direction while overlapping the lower parts 3a of each of the pair of clamp members 3 in the Y direction, so that the pair of clamp members 3 can be brought closer to each other. Can be done.

Specifically, each of the pair of clamp members 3 is provided with a stepped portion 32 . The step portion 32 is provided at a position between the lower end 31 and the upper end 33 of the inclined portion 30 in the Z direction. The lower portion 3a is a portion of the clamp member 3 that is on the lower side (Z2 side) than the stepped portion 32.

Moreover, as shown in FIG. 5, the upper parts 3b provided above the lower part 3a (Z1 side) of each of the pair of clamp members 3 are arranged so as to overlap each other when viewed from the X direction. There is. The upper portion 3b includes a portion where the terminal 200 is positioned in the Z direction, as will be described later.

As a result, the terminal 200 can be sandwiched in the X direction between the upper parts 3b that overlap each other when viewed from the X direction, so the terminal 200 can be positioned in the Z direction while the terminal 200 is stably fixed. It is possible.

Note that the upper portion 3b is provided continuously with the lower portion 3a with the stepped portion 32 as a boundary.

Further, as shown in FIG. 4, the thickness t1 of the lower portion 3a in the Y direction is constant regardless of the position in the Z direction. Further, the thickness t2 of the upper portion 3b in the Y direction gradually increases toward the upper side (Z1 side). Note that the minimum value of the thickness t2 is equal to the thickness t1.

Further, the distance D in the Z direction between the lower end 31 of the inclined part 30 and the upper end 33 of the inclined part 30 (see FIG. 7) is determined based on the variation in the position of the terminals 200 accommodated in the tray 101 in the Z direction. is set. Specifically, the distance D is set to 4 mm or more based on the fact that the position of the terminal 200 in the Z direction varies by approximately ±2 mm with respect to the reference position.

Further, as shown in FIG. 3, the terminal positioning device 100 is positioned at a height reference position P (see FIG. 5) above (Z1 side) than the lower end 31 of each inclined portion 30 of the pair of clamp members 3. A height positioning section 4 is provided. The height positioning section 4 positions the terminal 200 in the Z direction. Note that the height reference position P is an example of a "predetermined height reference position" in the claims.

The height positioning part 4 is provided at the lower end (Z2 side) of the columnar part 40. Note that the cylindrical portion 40 is provided so as to extend downward from a protruding portion 42 provided to protrude from a side surface 41a of a cylindrical portion 41 extending from the lower surface 2a of the actuator 2 downward (Z2 side).

The terminal positioning device 100 positions the terminal 200 on the upper side (Z1 The terminal 200 is positioned at the height reference position P by moving the terminal 200 to the side) and bringing it into contact with the height positioning part 4.

Thereby, by moving the terminal 200 along the inclined portions 30 of the pair of clamp members 3 and bringing the terminal 200 into contact with the height positioning portion 4, the terminal 200 is mechanically positioned at the height reference position P. Therefore, there is no need to detect the position of the terminal 200 in the Z direction using a camera and perform position correction. Therefore, the terminal 200 can be positioned in the Z direction without using a camera. Furthermore, since the terminal 200 can be positioned in the Z direction simply by bringing the pair of clamp members 3 close to each other, the positioning work can be simplified compared to the case where the terminal 200 is manually positioned in the Z direction. Can be done.

Further, each inclined portion 30 of the pair of clamp members 3 is provided so as to extend linearly when viewed from the Y direction.

Thereby, unlike the case where the inclined part 30 is not linear but curved, for example, the terminal 200 can be pressed upward (Z1 side) by the inclined part 30 with a constant force.

Specifically, the angle θ1 (see FIG. 7) between the inclined portion 30 and the X direction is, for example, 45 degrees. In this case, compared to the case where the angle θ is larger than 45 degrees, it is possible to increase the force that presses the terminal 200 upward (Z1 side). Furthermore, compared to the case where the angle θ is smaller than 45 degrees, it is possible to increase the range in which the terminal 200 can be moved upward (the range (stroke) in the Z direction in which the inclined portion 30 is provided). .

As the pair of clamp members 3 approach each other while sandwiching the terminal 200, the terminal 200 is pressed from the lower side (Z2 side) by the slope portions 30 of each of the pair of clamp members 3, and slides on the slope portion 30. It is moved upward (Z1 side). Note that the inclined portion 30 is polished so that its surface roughness is lower than that of other portions of the clamp member 3. Thereby, it is possible to prevent the terminal 200 from being damaged by friction with the inclined part 30 while moving along the inclined part 30 as much as possible.

Moreover, the height positioning part 4 is provided at the same height position as the upper end 33 of the inclined part 30 in the Z direction. Thereby, the terminal 200 comes into contact with the height positioning part 4 while being moved along the inclined part 30 by the thickness t3 (see FIG. 5) in the Z direction. Specifically, the terminal 200 is brought into contact with the height reference position P while being pressed from the lower side (Z2 side) by the inclined portion 30 on the upper part 3b of the clamp member 3. As a result, since the terminal 200 can be positioned in the Z direction while being pressed from below, the terminal 200 can be stably positioned in the height positioning section 4.

Furthermore, the terminal positioning device 100 positions the end portion 201a of the power line 201 connected to the terminal 200 in the Z direction by positioning the terminal 200 at the height reference position P using the pair of clamp members 3. It is composed of

Thereby, the end 201a of the power line 201 can be connected (welded) to another member (in this embodiment, the lead wire of the stator 104) with the end 201a of the power line 201 positioned in the Z direction.

Further, as shown in FIG. 3, the terminal positioning device 100 includes a pin member 5 provided so as to extend along the Z direction. The pin member 5 is provided to position the terminal 200 within a horizontal plane. The pin member 5 is provided so as to protrude downward (Z2 side) from the cylindrical portion 41. Note that the pin member 5 is made of iron, for example.

As shown in FIG. 5, the pin member 5 includes a tapered portion 50 provided at the lower end (Z2 side). The tapered portion 50 is provided so as to taper downward. In other words, the tapered portion 50 is formed in a tapered shape toward the lower side. That is, the outer diameter r1 of the tapered portion 50 gradually becomes smaller toward the lower side.

Thereby, it is possible to easily insert the pin member 5 into the hole 200b of the terminal 200.

Further, the pin member 5 includes a cylindrical columnar portion 51 provided above the tapered portion 50 . The outer diameter r2 of the cylindrical portion 51 is constant regardless of the position in the Z direction. Note that the cylindrical portion 51 is provided continuously with the tapered portion 50. That is, the maximum value of the outer diameter r1 of the tapered portion 50 is equal to the outer diameter r2 of the cylindrical portion 51.

The terminal positioning device 100 positions the terminal 200 in a horizontal plane by inserting the pin member 5 into a hole 200b provided in the terminal 200, and then positions the terminal 200 relative to the pin member 5 using a pair of clamp members 3. The terminal 200 is configured to be positioned in the Z direction by moving it relatively upward and bringing it into contact with the height positioning part 4.

Thereby, the terminal 200 can be positioned in the Z direction with the pin member 5 positioning the terminal 200 in the X direction and the Y direction.

The diameter r3 of the hole 200b is larger than the outer diameter r2 of the cylindrical portion 51 of the pin member 5. The difference (r3−r2) between the diameter r3 of the hole 200b and the outer diameter r2 of the cylindrical portion 51 is, for example, about 0.1 mm. The above difference is smaller than the thickness t3 of the terminal 200, for example.

As shown in FIG. 6, the terminal positioning device 100 is configured such that the pin member 5 is inserted into the hole 200b of the terminal 200, and the flat portion 200a of the terminal 200 is held between the pair of clamp members 3, so that the pin member 5 is inserted into the hole 200b of the terminal 200. It is configured to position the terminal 200 at the same time as to position the power line 201 connected to the terminal 200 in the rotational direction.

Thereby, it is possible to position the end portion 201a (see FIG. 3) of the power line 201 in the horizontal plane and in the rotational direction.

Specifically, when viewed from the Z2 side, the power line 201 is positioned (fixed) so as to be inclined, for example, by a predetermined angle θ2 with respect to the X direction.

Further, as shown in FIG. 5, the terminal positioning device 100 includes a guide portion 6 provided to guide the pin member 5 along the side surface 50a of the pin member 5. The lower end 60 of the guide part 6 is provided at the same height position (height reference position P) as the height positioning part 4 in the Z direction.

The lower ends 60 of the height positioning part 4 and the guide part 6 are provided so as to position the terminal 200 at the height reference position P in the Z direction by respectively abutting different parts of the terminal 200.

Accordingly, unlike the case where the terminal 200 is positioned only by the height positioning section 4, the terminal 200 can be positioned at two different points, so the terminal 200 can be positioned more stably.

Specifically, the lower end 60 of the guide portion 6 is provided so as to position the terminal 200 by coming into contact with the outer peripheral edge of the hole 200b of the terminal 200. Further, the height positioning portion 4 is provided so as to position the terminal 200 by coming into contact with a portion of the terminal 200 that is spaced apart from the hole portion 200b (a portion near the bent portion 200c, which will be described later).

Moreover, the height positioning part 4 includes a flat surface 4a provided so as to be orthogonal to the Z direction at the end on the Z2 side, and an outer peripheral edge part 4b provided so as to surround the flat surface 4a.

The outer peripheral edge portion 4b has an R shape (round shape) so as to follow the bent portion 200c having an R shape (round shape) provided on the terminal 200 when the flat surface 4a and the terminal 200 are in contact with each other. are doing.

Thereby, it is possible to prevent interference between the outer peripheral edge portion 4b and the bent portion 200c in a state where the flat surface 4a and the terminal 200 are in contact with each other. As a result, it is possible to bring the flat surface 4a and the terminal 200 into contact with each other more reliably. Further, it is possible to prevent the terminal 200 (bent portion 200c) from being damaged due to interference between the outer peripheral edge portion 4b and the bent portion 200c.

(Terminal positioning method)
Next, with reference to FIG. 7, a terminal positioning method in this embodiment will be described.

First, in step S1, the terminal positioning device 100 is moved to a predetermined position within the XY plane. Specifically, the terminal positioning device 100 is moved such that the center of the pin member 5 is located at the coordinates of the center of the hole 200b (see FIG. 6) of the terminal 200 in the XY plane.

Next, in step S2, the robot hand 105 (see FIG. 3) is driven to move the pair of clamp members 3 and pin members 5 to the Z2 side by a predetermined distance. Thereby, in the Z direction, the terminal 200 (lower end) is arranged in the range between the lower end 31 of the inclined part 30 and the upper end 33 of the inclined part 30. Further, at this time, the pin member 5 is inserted into the hole 200b of the terminal 200, so that the terminal 200 is positioned within the XY plane.

Next, in step S3, a pinching process is performed in which the terminal 200 is sandwiched in the X direction by the inclined portions 30 of each of the pair of clamp members 3 by bringing the pair of clamp members 3 closer to each other. In this step, the position of the power line 201 connected to the terminal 200 in the rotational direction is determined (the angle θ2 (see FIG. 6) is determined).

In step S4 after the clamping process (S3), the pair of clamp members 3 are brought closer to each other while clamping the terminal 200, so that the terminal 200 moves upward (toward the Z1 side) along the inclined portion 30 and abuts against the height positioning portion 4, thereby performing a height positioning process in which the terminal 200 is positioned at the height reference position P in the Z direction. As a result, the end portion 201a of the power line 201 is positioned in the Z direction.

As a result, the terminal 200 is mechanically positioned at the height reference position P by moving the terminal 200 along the inclined portions 30 of the pair of clamp members 3 and bringing the terminal 200 into contact with the height positioning portion 4. Therefore, there is no need to detect the position of the terminal 200 in the Z direction using a camera and perform position correction. Therefore, it is possible to provide a terminal positioning method that allows positioning of the terminal 200 in the Z direction without using a camera. Further, since the terminal 200 can be positioned in the Z direction simply by bringing the pair of clamp members 3 close to each other, the positioning work is simplified compared to the case where the terminal 200 is manually positioned in the Z direction. It is possible to provide a terminal positioning method that allows for

Specifically, the pair of clamp members 3 are moved from a state where they are separated from each other in the X direction to a position where their lower portions 3a (see FIG. 4) overlap each other when viewed from the Y direction.

Further, the height positioning step (S4) is a step that is performed continuously with the pinching step (S3).

Thereby, it is possible to shorten the time required to position the terminal 200 in the Z direction.

Specifically, the pair of clamp members 3 are continuously moved without stopping from when they start moving until the terminal 200 comes into contact with the height positioning section 4 .

For example, in the above embodiment, the positions of the lower parts 3a of the pair of clamp members 3 are shifted from each other when viewed from the X direction (first direction), and the upper parts 3b of the pair of clamp members 3 are shifted from each other when viewed from the X direction (first direction). Although an example is shown in which they overlap each other when viewed from the direction, the present invention is not limited to this. The upper parts 3b of the pair of clamp members 3 may be shifted in position from each other without overlapping each other when viewed from the X direction (first direction).

Further, in the above embodiment, an example was shown in which the inclined portion 30 is provided so as to extend linearly when viewed from the Y direction (second direction), but the present invention is not limited to this.

For example, the terminal 200 may be positioned using only one of the height positioning section 4 and the lower end 60 of the guide section 6.

Further, in the above embodiment, an example was shown in which the height positioning step (S4) is performed continuously with the pinching step (S3), but the present invention is not limited to this. For example, the movement of the clamp members 3 may be temporarily stopped when the pair of clamp members 3 come into contact with the terminal 200, and then the pair of clamp members 3 may be moved again (and moved closer to each other).
