<< Assembly manufactured using assembly manufacturing equipment >>
As shown in FIG. 1, the assembly 100 includes a first part 110, a second part 120, and a coil spring 130 (hereinafter referred to as a spring 130). The assembly 100 is assembled on a stand 30 described later in the specific manufacturing apparatus 10. Here, when assembling the assembly 100, the first component 110 is arranged on the −X side and the second component 120 is arranged on the + X side on the table 30. The axial direction of the spring 130 is equal to the X direction. In a state where the assembly 100 is assembled, the first component 110 and the second component 120 oppose each other in the axial direction of the spring 130 and compress the spring 130. In addition, the 1st component 110 and the 2nd component 120 are formed with nonmagnetic resin as an example.
Here, “first component 110” is an example of “component” in the present invention, and “second component 120” is an example of “other component” in the present invention. The “spring 130” is an example of the “cylindrical magnetic body” in the present invention.

The lateral direction (X direction) of the main body 112 is along the axial direction (X direction) of the spring 130. Further, the main body 112 is located on the −X side with respect to the spring 130. The pair of hooks 114 extend from both ends in the longitudinal direction (Z direction) of the main body 112 toward the + X side, and the tip portions thereof face each other (inward in the Z direction). In addition, a round hole 116 is formed at the center in the longitudinal direction of the main body 112 (position at a distance D from the end surface on the −Z side). The round hole 116 is recessed from the surface of the main body 112 toward the −X side. The “round hole 116” is an example of the “concave portion” in the present invention.

The short side direction (X direction) of the main body 122 is along the axial direction (X direction) of the spring 130. The main body 122 is located on the + X side with respect to the spring 130. The pair of hooks 124 extends from the outside in the longitudinal direction (Z direction) of the main body 122 slightly toward the -X side, and the tip portions thereof face each other (outside in the Z direction). The tip portions of the pair of hooks 124 are hooked on the tip portions of the pair of hooks 114 of the first component 110. The pin 126 is provided at the center in the longitudinal direction (Z direction) of the main body 122 (position at a distance D from the end surface on the −Z side) and protrudes from the surface of the main body 122 toward the −X side.

The depth of the third alignment groove 33C in the Y direction is slightly deeper than the width of the second component 120 in the Y direction. Further, the width in the X direction of the third alignment groove 33 </ b> C is slightly wider than the width in the X direction of the second component 120. That is, in the third alignment groove 33C, the second component 120 is movable along the Z direction.

  A part of the two partition plates 36, the right outer frame 34 </ b> B, and the lower outer frame 34 </ b> C are covered with a rectangular cover 38. The cover 38 is formed of an acrylic plate as an example, and the first alignment groove 33A, the third alignment groove 33C, and the movement groove 33D are visible.

Further, an insertion hole 38A into which the pin 74 is inserted is formed in a portion of the cover portion 38 corresponding to the pin 74 of the stopper portion 70 described later.

  Here, as shown in FIG. 2, in the moving groove 33D, a position that intersects when the second alignment groove 33B is extended to the −Z side (a position surrounded by a two-dot chain line in FIG. 2) is the first. Let it be position P1. The first position P1 is an arrangement place of the first component 110 in an initial state before the assembly of the assembly 100 is started (hereinafter simply referred to as “initial state”). Further, in the moving groove 33D, a position that intersects when the third alignment groove 33C is extended to the −Z side (a position surrounded by a two-dot chain line in FIG. 2) is defined as a second position P2. The second position P2 is an arrangement place of the second component 120 in the initial state.

  In the present embodiment, the plurality of first components 110 are arranged in a line from the first position P1 of the moving groove 33D to the second alignment groove 33B. Here, one first component 110 is disposed at the first position P1 while maintaining its orientation from the initial state to the completed state when the assembly of the assembly 100 is completed (hereinafter simply referred to as “completed state”). . That is, the first component 110 disposed at the first position P1 is held by the flat plate 32 and the lower outer frame 34C at the first position P1. That is, “the flat plate 32 and the lower outer frame 34 </ b> C” is an example of the “holding portion” in the present invention.

  Similarly to the first component 110, the second component 120 includes a plurality of second components 120 arranged in a line from the second position P2 of the moving groove 33D to the third alignment groove 33C. Here, the one second component 120 is arranged at the second position P2 in the initial state. Then, when the second component 120 arranged at the second position P2 moves from the initial state to the completed state, the second member 120 moves to the vicinity of the first position P1 while maintaining the direction thereof as the push member 40 moves to the −X side. To do. That is, the second component 120 arranged at the second position P2 is held by the flat plate 32, the lower outer frame 34C, and the pressing member 40 from the second position P2 toward the first position P1. That is, “the flat plate 32, the lower outer frame 34C, and the pressing member 40” is an example of “another holding portion” in the present invention.

  Further, the plurality of springs 130 are arranged in a line with a stop portion 70 (to be described later) of the first alignment groove 33A, which will be described later. Although details will be described later, one spring 130 falls from the first alignment groove 33A to the movement groove 33D from the completed state to the initial state. And when returning to an initial state, this one spring 130 is arrange | positioned in the 3rd position P3. When the spring 130 arranged at the third position P3 moves from the initial state to the completed state, the spring 130 moves to the first position P1 while maintaining its orientation as the push member 40 moves to the −X side. That is, the axial direction moves along the X direction.

  Although the positions P1, P2, and P3 have been briefly described above, the details of the positions P1, P2, and P3 will be supplemented in the description of the method for manufacturing the assembly 100. Note that the front surface 32A and the back surface 32B of the present embodiment are flat as an example, as shown in FIG. That is, in the present embodiment, the base 30 can arrange the spring 130 along the moving groove 33D. Here, “along the spring 130 along the movement groove 33 </ b> D” means “along the axial direction of the spring 130 along the X direction”.

<Pushing member>
When the assembly 100 is manufactured, the pushing member 40 pushes the second component 120 and the spring 130 from the + X side and moves them to the −X side (see FIGS. 2 and 6 to 8). As shown in FIG. 2, the pressing member 40 is formed in a square bar shape. The width of the pushing member 40 in the Z direction is slightly narrower than the width of the moving groove 33D in the Z direction, and the width of the pushing member 40 in the Y direction is slightly narrower than the depth of the moving groove 33D in the Y direction. That is, the push member 40 is movable along the X direction. Here, the “pushing member 40” is an example of the “moving part” in the present invention.

The pushing member 40 in the initial state is disposed at a position where the -X side surface is continuous with the -X side surface of the right outer frame 34B (see FIG. 2). Further, the pressing member 40 in the completed state has the −X side surface disposed near the first position P1 (see FIG. 8).
The push member 40 is supported by a guide (not shown) so as to be movable along the X direction, and is moved in the X direction by a driving device (not shown). This movement is performed based on an operator operating a start switch (not shown) in a first step of the method of manufacturing the assembly 100 described later.

<Magnet>
The magnet 50 forms a magnetic field in the moving groove 33D. In the present embodiment, the magnet 50 includes a first magnet 52 (see FIG. 4A) disposed on the left outer frame 34A, and a second magnet 54 (see FIG. 2) disposed on the lower outer frame 34C. It has. The first magnet 52 and the second magnet 54 of the present embodiment have a thickness in the Y direction, and the thickness is slightly thinner than the outer diameter of the spring 130. That is, the thicknesses of the first magnet 52 and the second magnet 54 of the present embodiment are set to be equal to or smaller than the outer diameter of the spring 130. The first magnet 52 and the second magnet 54 are permanent magnets. Here, “first magnet 52” and “second magnet 54” are examples of “magnet” and “other magnet” in the present invention, respectively.

<First magnet>
As shown in FIG. 4A, the first magnet 52 is formed in a disk shape having a thickness in the Y direction. As shown in FIG. 4A, the first magnet 52 is fitted in a hole formed in the left outer frame 34A. Further, when observed from the Z direction, the first magnet 52 is symmetric with respect to the apex 52A closest to the X direction at the −X side end of the moving groove 33D and is separated from the apex 52A in the X direction. Accordingly, the moving groove 33D has a side portion 52B having a large separation distance from the end portion on the −X side. Here, the side portion 52B having a large separation distance from the end portion on the −X side of the moving groove 33D refers to a portion other than the top portion 52A on the outer periphery of the first magnet 52 in FIG. .

  In the present embodiment, the first magnet 52 forms a magnetic field near the first position P1 of the moving groove 33D. The first magnet 52 has an N-pole on the + Y side and an S-pole on the −Y side (not shown) with the center in the Y direction as a boundary. Therefore, the direction of the magnetic field of the first magnet 52 is from the N pole to the S pole, and when viewed from the Z direction, an annular magnetic field line extending from the + Y side to the −Y side extends (not shown). Accordingly, the first magnet 52 forms a magnetic field in the vicinity of the first position P1 of the moving groove 33D.

  FIG. 4A shows a plurality of lines of equal magnetic force (two-dot chain lines in the figure) with the same magnetic force interval by the first magnet 52. As shown in FIG. 4A, the interval between the isomagnetic lines increases as the distance from the outer periphery increases in the X direction. For this reason, the magnetic flux density on the moving groove 33D formed by the first magnet 52 is maximized at the position closest to the top 52A, and decreases symmetrically as the distance from the position closest to the top 52A increases to both ends in the Z direction. That is, at the first position P1 (see FIG. 2), a magnetic field having the maximum magnetic flux density is formed at a position closest to the top 52A.

  In the present embodiment, the position of the top 52A in the Z direction is equal to the center of the round hole 116 of the first component 110. Furthermore, the position of the center of the top portion 52 </ b> A in the Y direction is equal to the center of the round hole 116 of the first component 110. Therefore, when the spring 130 approaches the first position P <b> 1, one end of the spring 130 moves toward the round hole 116 by the magnetic force of the first magnet 52.

<Second magnet>
Similarly to the first magnet 52, the second magnet 54 forms a magnetic field in the moving groove 33D. The second magnet 54 is formed in a rectangular shape having a thickness in the Y direction. The second magnet 54 is fitted in a hole formed in the lower outer frame 34C.

  Further, the second magnet 54 has an N pole on the + Y side and an S pole on the −Y side (not shown) with the center in the Y direction as a boundary. Therefore, the direction of the magnetic field of the second magnet 54 is from the N pole to the S pole, and when viewed from the Z direction, an annular magnetic field line extending from the + Y side to the −Y side extends (not shown). Thereby, the second magnet 54 forms a magnetic field in the moving groove 33D. The second magnet 54 has a function of disposing the spring 130 supplied to the third position P3 at the third position P3 so that the axial direction thereof is along the X direction. The function of the second magnet 54 will be described later.

<Spring supply part>
The spring supply part 55 is for supplying the one spring 130 to the moving groove 33D when the assembly 100 is manufactured. Here, the “spring supply section 55” is an example of the “supply section” in the present invention. As shown in FIG. 2, the spring supply unit 55 includes a stop unit 70 and a release unit 60.

<Stopping part>
The stopper 70 is provided on the first alignment groove 33A and prevents the spring 130 from moving to the movement groove 33D.
As shown in FIG. 5, the stopper 70 includes a disk-shaped head 72 and a pin 74 that extends from the center of the head 72 toward the −Y side. The stopper 70 is pressed by the pressing member 76 toward the −Y side of the head 72. Then, when the pin 74 comes into contact with the spring 130 in the first alignment groove 33A, the spring 130 is stopped at the spot.

The pin 70 is inserted into the insertion hole 38 </ b> A of the cover 38 and the stopper 70 is movable in the Y direction. That is, the stopper 70 is restricted by the movement in the X direction and the Z direction coming into contact with the cover 38. At this time, the pin 74 of the stopper 70 protrudes toward the −Y side through the insertion hole 38A.
The initial state of the stopper 70 includes an initial state before starting the assembly of the first assembly 100 (see FIG. 5A) and an initial state before starting the assembly of the second and subsequent assemblies 100. (See FIG. 5C). 5A, in the initial state of the first assembly 100, the stopper 70 is in contact with the head 72 and the cover 38, and the pin 74 is in the first alignment groove 33A. Has reached the bottom. Further, as shown in FIG. 5C, the stopper 70 has a pin 74 which is not in contact with the head 72 and the cover 38 in the initial state of the second and subsequent assemblies 100, and the pin 74 is a spring 130. It is in contact with the outer peripheral surface. On the other hand, as shown in FIG. 5 (B), the stopper portion 70 has a hook 66 of a release portion 60 (described later) inserted between the head portion 72 and the cover portion 38 in the completed state. The contact with the cover 38 is released.

<Release section>
The release part 60 releases the rest of the spring 130 by the stop part 70 by lifting the stop part 70 to the + Y side against the pressing force of the pressing member 76. As shown in FIG. 2, the release portion 60 is formed along the push member 40, that is, along the X direction. The release unit 60 is disposed so as to contact the cover unit 38. The release portion 60 includes a plate-shaped body portion 62, a hook 66, and a contact portion 64.

The width of the trunk 62 is slightly wider than the head 72 of the stopper 70 in the short direction (Z direction).
The hooks 66 extend from both ends in the short direction (Z direction) of the body portion 62 toward the −X side. Further, as shown in FIG. 5, the tip side (−X side) of the hook 66 is formed so that the thickness in the Y direction decreases from the + X side to the −X side. That is, the tip end side (−X side) of the hook 66 is an inclined surface 66 </ b> A formed with a downward inclination toward the cover portion 38. The hook 66 lifts the head 72 to the + Y side when the inclined surface 66 </ b> A enters between the head 72 of the stopper 70 and the cover 38.

  The contact portion 64 is a side surface on the −X side of the body portion 62 and is a portion between the pair of hooks 66. The width of the pair of hooks 66 is narrower than the width of the head 72 in the Z direction and wider than the outer diameter (Z direction) of the pin 74. The contact portion 64 is a portion that contacts the pin 74 of the stop portion 70 when the inclined surface 66A of the hook 66 enters between the head portion 72 and the cover portion 38. That is, the contact portion 64 functions as a stopper for preventing the release portion 60 from moving to the −X side. The release portion 60 is positioned on the right outer frame 34B in the initial state, and is formed so that the contact portion 64 contacts the pin 74 in the completed state.

Here, the release unit 60 of the present embodiment is connected to the push member 40 by a link mechanism (not shown), and can move in the X direction in conjunction with the push member 40. Specifically, when the push member 40 moves from the initial state to the completed state, the release unit 60 moves toward the −X side in conjunction with the movement of the push member 40. Further, when the pushing member 40 moves from the completed state to the initial state again, the release unit 60 moves toward the + X side in conjunction with the movement of the pushing member 40.
The above is the description of the specific manufacturing apparatus 10 of the present embodiment.

≪Method of manufacturing assembly≫
Next, the manufacturing method of the assembly 100 using the specific manufacturing apparatus 10 of this Embodiment is demonstrated, referring drawings. The manufacturing method of the assembly 100 includes a first step, a second step, and a third step described below. The assembly 100 is manufactured automatically using the specific manufacturing apparatus 10 except for an operation in which an operator operates the start switch.

<First step>
The first step is a step from the initial state until the second member 120 and the spring 130 are moved to the −X side by the pushing member 40 and moved to insert one end of the spring 130 into the round hole 116.

First, as shown in FIG. 2, the operator does not illustrate the first part 110 in the first position P1, the second part 120 in the second position P2, and the spring 130 in the third position P3. When the start switch is operated, the first step is started. In addition, arrangement | positioning to the 1st position P1 of the 1st component 110, arrangement | positioning to the 2nd position P2 of the 2nd component 120, and arrangement | positioning to the 3rd position P3 of the spring 130 are performed at the 3rd process mentioned later.
When the operator operates the start switch, the push member 40 starts moving, and the second component 120 that is in contact with the front end surface (the −X side surface) of the push member 40 is disposed at the second position P2. It is moved while being pushed out by the pushing member 40 toward the -X side while maintaining the orientation when being pushed.

When the second component 120 is moved while being pushed toward the −X side by the pressing member 40, the second component 120 contacts the spring 130. For example, the main body 122 of the second component 120 is contacted. Then, the spring 130 is moved together with the second component 120 while being pushed out toward the −X side by the pushing member 40.
Thereafter, as shown in FIG. 6, when the spring 130 reaches the first position P <b> 1, the magnetic force of the first magnet 52 starts to be attracted toward the first magnet 52.

  At this time, as described above, at the first position P1, the position closest to the top portion 52A is the maximum magnetic flux density position, so that one end of the spring 130 is drawn toward the top portion 52A. Then, one end of the spring 130 is inserted into the round hole 116 of the first component 110 at a position corresponding to the top 52A. The above is the first step.

  When the second component 120 arranged at the second position P2 is moved while being pushed out to the −X side by the pushing member 40, the second component 120 arranged next to the moved second component 120. Contacts the + Z side surface of the push member 40 (see FIGS. 6 to 9). Therefore, the next second component 120 cannot fall into the moving groove 33D by its own weight and is not disposed at the second position P2.

As described above, the release unit 60 moves to the −X side in conjunction with the movement of the pressing member 40 to the −X side, and therefore moves as follows in the first step.
The release portion 60 in the first step moves to the −X side from the initial state shown in FIG. 2 in conjunction with the movement of the push member 40 to the −X side, and the head 72 of the stop portion 70 is inclined 66A. (See FIG. 7).

  Here, in the initial state, as shown in FIG. 5A, in the release unit 60, the hook 66 is positioned on the right outer frame 34B. At this time, in the stop portion 70, the outer peripheral surface of the pin 74 is in contact with the lower end portion (−Z side end portion) of the spring 130, so that the spring 130 in the first alignment groove 33 </ b> A moves to the moving groove 33 </ b> D. Is preventing. Therefore, in the initial state, the spring 130 does not fall into the moving groove 33D.

  On the other hand, in a state where the release portion 60 has moved from the initial state to the −X side, the head portion 72 of the stopper portion 70 is lifted by the inclined surfaces 66A of the pair of hooks 66 as shown in FIG. When the gap between the pin 74 and the first alignment groove 33A exceeds the outer diameter of the spring 130, the spring 130 moves toward the moving groove 33D by its own weight. However, since the pushing member 40 is moved in the moving groove 33D, the spring 130 is blocked by the + Z side surface of the pushing member 40 and does not fall into the moving groove 33D.

<Second step>
The second process is a process from assembling the second part 120 to the first part 110 and inserting the pin 126 into the other end of the spring 130 until the assembly 100 is completed. The second step is performed continuously to the first step.

  First, in a state where the first step is completed, one end of the spring 130 is inserted into the round hole 116 as shown in FIG. When the second component 120 is further pressed toward the first position P1 by the pressing member 40 in a state where the second component 120 and the first component 110 face each other, the ends of the pair of hooks 124 are paired with each other. The second part 120 is fitted into the first part 110 by getting over the tip of the hook 114. Further, the pin 126 of the second component 120 is inserted into the other end of the spring 130. The pushing member 40 pushes out the second component 120 until the main body 122 contacts the pair of hooks 114. In addition, since the distance between the main body 122 and the main body 112 is shorter than the free length of the spring 130, the spring 130 is in a compressed state. As described above, the first part 110, the second part 120, and the spring 130 are combined to complete the assembly 100, and the second step is completed.

In addition, the cancellation | release part 60 in a 2nd process moves as follows.
First, the release unit 60 in the second step moves further from the state at the end of the first step shown in FIG. 7 to the −X side in conjunction with the movement of the pressing member 40 to the −X side, and is in a completed state. In FIG. 8, the contact portion 64 moves to a position where it comes into contact with the pin 74 (see FIG. 8).

  In the completed state, the release unit 60 lifts the stopper 70 to the + Y side along the inclination of the inclined surface 66A. As described above, when the gap between the pin 74 and the first alignment groove 33A exceeds the outer diameter of the spring 130 (see FIG. 5B), the spring 130 moves toward the moving groove 33D by its own weight. However, since the pushing member 40 is moved in the moving groove 33D, it is blocked by the + Z side surface of the pushing member 40, so the spring 130 does not fall into the moving groove 33D.

<Third step>
The third step is a step from the completed state to the initial state again. Specifically, the step of arranging the next second component 120 and the spring 130 constituting the next assembly 100 at the second position P2 and the third position P3, respectively, by returning the pushing member 40 to the initial state position. It is. The third step is performed continuously with the second step.

  First, as shown in FIG. 9, the pushing member 40 starts moving toward the + X side. Here, as a result of the release of the contact between the front end surface of the push member 40 (the surface on the −X side) and the second component 120, the spring 130 compressed between the first component 110 and the second component 120 is restored. Try to return to the state. As a result, the spring 130 pushes the first part 110 and the second part 120 away from each other, whereby the assembly 100 shown in FIG. 1 is obtained.

  Next, when the tip end surface (the −X side surface) of the pressing member 40 reaches the first alignment groove 33A (see FIG. 9) and further passes through the first alignment groove 33A, the + Z side surface of the pressing member 40 and The spring 130 that has been in contact loses support and falls toward the moving groove 33D by its own weight (see FIG. 10). As shown in FIG. 10, the spring 130 falls in the direction in which the axial direction is along the first alignment groove 33 </ b> A, in other words, in the Z direction, but reaches the lower outer frame 34 </ b> C, and the magnetic force of the second magnet 54. Is pulled toward the second magnet 54. As a result, the spring 130 is attracted to the + X side by the magnetic force of the second magnet 54, and is disposed at the third position P3 in a sideways state (a state in which the axial direction of the spring 130 is along the X direction).

  Further, when the push member 40 moves to the + X side and moves to the position in the initial state, that is, the tip surface (the -X side surface) of the push member 40 continues to the -X side surface of the right outer frame 34B. The second component 120 that has been in contact with the + Z side surface of the pressing member 40 falls due to its own weight and is disposed at the second position P2.

  As described above, the second member 120 and the spring 130 are disposed at the second position P2 and the third position P3, respectively, by moving the push member 40 to the initial position, and thus the third step is completed. When the third step is completed, the operator takes out the assembly 100 completed in the second step, so that the first component 110 constituting the next assembly 100 is arranged at the first position P1. . Specifically, the first part 110 constituting the next assembly 100 is arranged above (+ Z side) the first part 110 of the assembly 100 in the completed state. The first part 110 above the first part 110 of the assembly 100 in the completed state (+ Z side) loses support and falls due to its own weight, and is disposed at the first position P1. The

The release unit 60 in the third step moves to the + X side in conjunction with the movement of the pressing member 40 to the + X side, and moves to the initial position (see FIGS. 9 and 10).
Here, as shown in FIG. 9, when the inclined surfaces 66 </ b> A of the pair of hooks 66 are separated from the head 72 of the stopper 70, the stopper 70 moves to the −Y side by the pressing force of the pressing member 76.
Here, as shown in FIG. 5C, when the stopper 70 moves to the -Y side, the spring 130 is sandwiched between the tip end portion (-Y side) of the pin 74 and the first alignment groove 33A. This prevents the spring 130 from moving to the moving groove 33D.

And according to the manufacturing method of the assembly 100 using the specific manufacturing apparatus 10 in the present embodiment, the assembly 100 is mass-produced by returning to the first step and repeating the steps up to the third step. be able to.
The above is the description of the method for manufacturing the assembly 100 of the present embodiment.

<Effect>
Next, the effect of this Embodiment is demonstrated.

<First effect>
The first operation effect is an operation effect of the first magnet 52 having a top portion 52A that is closest to one end of the moving groove 33D when viewed from the Z direction (hereinafter referred to as a specific requirement). The first effect will be described by comparing the present embodiment with the comparative embodiment. In addition, when using the component etc. which were used by this Embodiment in the comparison form, it demonstrates using the code | symbol, name, etc. of the component as it is.

First, a comparative embodiment will be described with reference to FIG.
The specific manufacturing apparatus 10 </ b> A of the comparative form includes a base 30 </ b> A, a pressing member 40, and a moving device 80. The base 30A includes a long flat plate 32C and an outer frame 34D. The outer frame 34D is provided in a portion on the outer peripheral side of the surface of the flat plate 32C and other than a part on the + X side (hereinafter referred to as “a portion without the outer frame 34D”). The pushing member 40 is moved in the X direction through a portion where the outer frame 34D is absent. Further, on the surface of the base 30A, the first component 110 is disposed at a position on the −X side (referred to as a first position P1), and a second component is disposed at a position on the + X side (referred to as a second position P2). 120 is arranged. In this case, the first component 110 and the second component 120 are arranged so that the sides on which the pair of hooks 114 and 124 extend face each other.

  The moving device 80 grips the spring 130 disposed at a position away from the table 30A (fourth position P4 in the figure), and moves the spring 130 to the fifth position P5 in the center in the X direction of the table 30A. It is like that. The moving device 80 is configured to hold the spring 130 moved to the fifth position P5 at the fifth position P5 in a state where the axial direction is along the X direction. That is, the moving device 80 according to the comparative embodiment is a robot having a function of holding the spring 130, moving the spring 130, and holding the moved spring 130 in a predetermined direction.

  With the above configuration, in the comparative embodiment, the assembly 100 is manufactured as follows. First, the worker arranges the first component 110 at the first position P1, and arranges the second component 120 at the second position P2. Next, the operator operates the moving device 80 to move the spring 130 disposed at the fourth position P4 to the fifth position P5. The spring 130 moved to the fifth position P5 is held while being held by the moving device 80 in a state where the axial direction thereof is along the X direction. Next, the operator moves the push member 40 from the + X side to the −X side to move the second part 120 at the second position P2 from the + X side to the −X side of the table 30A, and the moving device 80 moves the second part 120. The pin 126 of the second component 120 is inserted into the other end of the spring 130 held at the fifth position P5. Next, the operator operates the moving device 80 to release the moving device 80 from the spring 130. Further, the operator moves the second member 120 by moving the push member 40 from the + X side of the base 30A to the -X side, and inserts one end of the spring 130 into the pin 118 of the first component 110, and then The tips of the pair of hooks 124 of the second component 120 are fitted into the tips of the pair of hooks 114 of the first component 110 at the first position P1. The assembly 100 is manufactured through the above steps, and the manufacturing method of the assembly 100 of the comparative form is completed.

  As described above, in the comparative example, the moving device 80 (robot) is used to move the spring 130 from the fourth position P4 to the fifth position P5 and to move the spring 130 moved to the fifth position P5 in the axial direction. Needs to be held along the X direction. In the case of the comparative example, it is necessary to cancel the holding of the spring 130 by the moving device 80 at the timing when the pin 126 of the second component 120 is inserted into the other end of the spring 130 held at the fifth position P5.

  On the other hand, in the case of the present embodiment, as described above, there are specific requirements (see FIG. 4A). Therefore, according to the present embodiment, the axial direction after the movement of the spring 130 can be positioned along the direction of the movement groove 33D (X direction) without using the moving device 80 as in the comparative embodiment. Furthermore, the spring 130 can be inserted into the round hole 116 (see FIG. 7).

  Therefore, according to the specific manufacturing apparatus 10 of the present embodiment, it is simpler than the case where the moving device 80 grips the spring 130, moves the gripped spring 130, and positions the spring 130 while gripping. In a configuration (or in a short time), the spring 130 can be inserted into the round hole 116 of the first part 110 in a defined orientation. Furthermore, according to the specific manufacturing apparatus 10 of the present embodiment, it is simpler than the case where the moving device 80 grips the spring 130, moves the gripped spring 130, and positions the spring 130 while gripping. The assembly 100 can be manufactured in a configuration (or in a short time). Moreover, according to the specific manufacturing apparatus 10 of the present embodiment, the moving device 80 grips the spring 130, moves the gripped spring 130, and is simpler than the case where the spring 130 is gripped and positioned. In the configuration (or in a short time), the spring 130 can be positioned such that its axial direction is along the X direction.

<Second effect>
The second effect is an effect that the thickness of the first magnet 52 is equal to or less than the outer diameter of the spring 130.

  According to the test and research by the inventors of the present application, the spring 130 is positioned at any position in the range of the first magnet 52 in the Y direction at the first position P1. Therefore, when the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130, the spring 130 can be attracted, but the position of the spring 130 in the Y direction of the first magnet 52 is a range in the Y direction of the first magnet 52. Inside.

  Therefore, when the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130, the position of the spring 130 attracted and attracted to the first magnet 52 and the position of the pin 126 of the second component 120 in the Y direction. Deviation may occur. As described above, when a deviation in the Y direction occurs between the position of the spring 130 and the position of the pin 126 of the second component 120, the pin 126 is moved even if the second component 120 moves to the -X side. 130 cannot be inserted into the other axial end. In other words, when a deviation in the Y direction occurs between the position of the spring 130 and the position of the pin 126 of the second component 120, the assembly 100 cannot be completed. Further, when the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130, even if the spring 130 is pulled toward the first magnet 52, a deviation in the Y direction occurs due to the positional relationship with the round hole 116. And the assembly 100 may not be completed.

  On the other hand, the thickness of the first magnet 52 of the present embodiment is set to be equal to or smaller than the outer diameter of the spring 130. Therefore, in the case of the present embodiment, the first magnet 52 is positioned in a narrow range in the Y direction as compared with the case where the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130.

  Therefore, according to the specific manufacturing apparatus 10 of the present embodiment, the spring 130 is positioned in a narrow range in the Y direction of the first magnet 52 as compared with the case where the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130. can do. Furthermore, according to the specific manufacturing apparatus 10 of the present embodiment, the round hole 116 of the first component 110 and the pin of the second component 120 are compared with the case where the thickness of the first magnet 52 is thicker than the outer diameter of the spring 130. Both ends of the spring 130 in the axial direction can be easily inserted into 126 (or the insertion rate is high).

<Third effect>
The third effect is an effect of the second magnet 54 being disposed on the lower outer frame 34C.

  In the third step in the manufacturing method of the assembly 100 of the present embodiment, as described above, the spring 130 that has been in contact with the + Z side surface of the pressing member 40 is supported by the movement of the pressing member 40 to the initial state. And fall into the moving groove 33D by its own weight.

At this time, in the method for manufacturing the assembly 100 of the present embodiment, the spring 130 falls in the direction in which the axial direction of the spring 130 extends along the first alignment groove 33A, in other words, in the Z direction, but reaches the lower outer frame 34C. When the magnetic force of the second magnet 54 reaches, it is drawn toward the second magnet 54.
Thereby, according to the manufacturing method of the assembly 100 of this Embodiment, the spring 130 can be moved to the -X side from the state which laid down in the X direction beforehand.

  According to the study by the inventors of the present application, a state other than a state where the spring 130 is laid down, for example, a state where the axial direction of the spring 130 is along the Z direction (hereinafter referred to as “vertical state”) is shifted to the −X side. When moved, one end of the spring 130 in the axial direction could not be inserted into the round hole 116. This is because the part other than one end in the axial direction of the spring 130 entered the magnetic field of the first magnet 52 first, and the part of the spring 130 that first entered the magnetic field of the first magnet 52 aimed at the top 52A. This is presumed to be due to being drawn.

  On the other hand, according to the manufacturing method of assembly 100 of the present embodiment, spring 130 can be moved to the −X side in a state where the spring 130 is laid down in the X direction in advance. Therefore, according to the method for manufacturing assembly 100 of the present embodiment, the axial direction of spring 130 can be moved along the X direction, and the axis of spring 130 is first applied to the magnetic field of first magnet 52. One end of the direction can be entered.

  Therefore, according to the specific manufacturing apparatus 10 of the present embodiment, the spring 130 for the round hole 116 is compared with the case where the spring 130 is moved to the −X side from the state in which the spring 130 is disposed in the vertical position in the third position P3. The insertion rate at one end in the axial direction can be increased.

<Fourth effect>
The fourth effect is an effect of the spring supply unit 55 being arranged on the table 30.
In the manufacturing method of the assembly 100 according to the present embodiment, the stopper 70 is lifted to the + Y side by the release portion 60, and then the pushing member 40 moves to the + X side, whereby the spring constituting the next assembly 100 is obtained. 130 is supplied to the moving groove 33D. Specifically, as described above, the spring 130 is disposed at the third position P3 by the second magnet 54 after being supplied to the moving groove 33D.

Thereby, according to the manufacturing method of the assembly 100 of this Embodiment, when the manufacturing process of the assembly 100 is completed, the spring 130 which comprises the next assembly 100 is automatically supplied to the moving groove 33D. can do.
Therefore, according to the manufacturing method of assembly 100 of the present embodiment, it is easier (or in a shorter time) than a configuration in which spring 130 is not supplied to moving groove 33D when the manufacturing process of assembly 100 is completed. The next assembly 100 can be completed.
