Description

  The present invention relates to a component assembling apparatus that automatically assembles a plurality of components one above the other.

  Conventionally, a method for assembling a plurality of components by vertically stacking them is known (for example, Patent Document 1).

JP-A-10-310254

  When assembling parts by stacking them up and down, the stacked parts may be displaced or detached when the parts are stacked or when the stacked parts are moved up and down. In particular, in a small component, the unevenness may be extremely shallow, and there is a problem that the assembled component is displaced or detached when a force in the vertical direction (antigravity direction and gravity direction) is applied.

  An object of the present invention is to stably assemble parts when the parts are assembled one above the other.

  A component assembly apparatus according to an exemplary embodiment of the present application is a component assembly apparatus that assembles a plurality of components stacked in the gravity direction, and includes a pedestal unit, a component transfer unit, a component support unit, and a first drive unit. And a control unit that controls the first drive unit and the second drive unit, the pedestal unit has a horizontal component transfer surface at the top and a recess that opens upward. The component transfer unit can transfer components on the component transfer surface. The component support portion can move up and down in the recess and has a support surface capable of supporting the component transferred by the component transfer portion from below. The first drive unit drives the component transfer unit. The second drive unit moves the component support unit up and down. When the control unit drives the first drive unit and transfers one component by the component transfer unit, the upper surface of another component supported by the component support unit by driving the second drive unit is the same as the component transfer surface. The component support part is moved up and down so that the position is lower than one or the component transfer surface.

  According to the component assembly apparatus of an exemplary embodiment of the present application, when the component transfer unit transfers one component to the component support unit, the upper surface of the other component supported by the component support unit is substantially the same as the component transfer surface. It is held in a position that is flush. As a result, the parts to be input are transferred along the part transfer surface, and are stacked on other parts while maintaining substantially the same level, thereby assembling the parts. For this reason, it is hard to receive the impact of an up-down direction at the time of an assembly, and components can be assembled stably.

An example of

  Hereinafter, a component assembling apparatus according to an embodiment of the present invention will be described with reference to the drawings. Note that the scope of the present invention is not limited to the following embodiments, and can be arbitrarily changed within the scope of the technical idea of the present invention.

  In the following drawings, the scale and number of each structure may be different from the scale and number of an actual structure in order to make each configuration easy to understand.

  As used herein, “upper”, “lower”, “upper”, “lower”, “upper”, “lower”, “upper”, “lower”, “vertical”, “horizontal”, “side” As well as other similar terms refer to relative positions as shown in the figures. These representations are used for illustrative purposes only, and the actual implementation of the structures described herein may be spatially arranged in any direction or manner.

  In the following, “assembled part” represents a part assembled by the part assembling apparatus according to the present embodiment. Regarding the rotor parts exemplified in the present embodiment, the “assembly part” is an assembly of the rotor member P1 and the magnet P2, and is in a state before the shaft is inserted (for example, as shown in FIG. 10C). Stuff).

  In the present embodiment, an explanation will be given taking as an example the assembly of a rotor member and a magnet, which are parts of the hybrid stepping motor shown in FIGS. 10 (a) to 10 (c). 10A shows the rotor member P1, FIG. 10B shows a state in which the magnet P2 is superimposed on the rotor member P1, and FIG. 10C shows an assembled state. The number of rotor members P1 and magnets P2 in the assembled state is not limited to those shown in the figure, but a combination with a smaller number (for example, two rotor members and two magnets for one magnet). (E.g., three rotor members) and more combinations are possible.

  The rotor of the hybrid stepping motor is assembled such that the magnet P2 is sandwiched between the rotor members P1. After assembling the rotor member P1 and the magnet P2, the rotor member P1, the magnet P2, and the shaft are fixed to each other by inserting a shaft (not shown) into the center hole (press-fitting, bonding, etc.) to complete the rotor. . Therefore, the rotor member P1 and the magnet P2 are not fixed before the shaft is inserted. In particular, the rotor member P1 and the magnet P2 often have a very small thickness of 1 mm or less. For this reason, for example, in the state in the middle of assembly as shown in FIG. 10B, the rotor member P1 floats due to a drop shock or the like, and the position of the magnet P2 is shifted or detached from the rotor member P1.

  The component assembly apparatus according to the present embodiment is intended to solve such a problem and to assemble a stable component.

The component support part 12 has a support surface 12a for supporting a rotor member P1 and a magnet P2 transferred by a component transfer part 30 described later on the upper surface thereof.

  The elevating part 13 has a screw shape (not shown) and is provided through the component support part 12. The elevating unit 13 moves the component support unit 12 up and down by rotating by the drive of the connected elevating drive unit 53.

<Parts transfer section>
As shown in FIG. 1, the component assembling apparatus 1 further includes a component transfer unit 30 (an example of a component transfer unit). The component transfer unit 30 includes a first component transfer unit 31 (an example of a first component transfer unit) and a second component transfer unit 32 (an example of a second component transfer unit). As shown in FIG. 3, the first component transfer unit 31 and the second component transfer unit 32 are arranged so as to face each other with the pedestal unit 11 interposed therebetween. The first component transfer unit 31 and the second component transfer unit 32 are driven by a first component transfer drive unit 51 and a second component transfer drive unit 52 (FIG. 6), which will be described later, in a horizontal direction with respect to the pedestal unit 11. By moving forward and backward, the components on the component transfer surface 15 are transferred to the component support portion 12.

As shown in FIG. 1, FIG. 4A and FIG. 4B, the component assembling apparatus 1 includes a component pressing portion 16 (an example of a pressing portion). As shown in FIG. 1, the component pressing portion 16 is a component in the middle of assembly by elastically pressing the rotor member P1 and / or the magnet P2 supported on the component supporting portion 12 from above with an urging force such as a spring. Prevents misalignment or disengagement.

  FIG. 4A is a perspective view of the component pressing portion 16. The component pressing portion 16 has a lower surface 16 a on the lower side, that is, on the side facing the component support portion 12. The component pressing unit 16 further faces the moving directions of the first component transfer unit 31 and the second component transfer unit 32, and the inclined surfaces 161 and 162 guide the components transferred on the component transfer surface 15 onto the component support unit 12. (An example of an inclined surface) is formed. The inclined surface 161 is formed in the direction in which the first component transfer unit 31 moves, and the inclined surface 162 is formed in the direction in which the second component transfer unit 32 moves. The inclined surface 161 guides the rotor member P <b> 1 transferred by the first component transfer unit 31 onto the component support unit 12. The inclined surface 162 guides the magnet P <b> 2 transferred by the second component transfer unit 32 onto the component support unit 12. In the present embodiment, the inclined surfaces 161 and 162 are formed in a size and an angle that match the size or height of the guided component.

  The component pressing portion 16 is biased downward, and the component pressing portion 16 is arranged as follows. The distance between the lower surface 16a of the component pressing portion 16 and the support surface 12a of the component supporting portion 12, or the distance between the lower surface 16a of the component pressing portion 16 and the upper surface of the uppermost component supported on the component supporting portion 12 is The thickness of the component transferred to the component transfer unit 30 is smaller than the thickness in the vertical direction. In FIG. 4B, the vertical position of the upper surface of the support surface 12a of the component support portion 12 or the uppermost component supported on the component support portion 12 is H. When the distance between the lower surface 16a and H is L1, and the length in the vertical direction of the magnet P2, which is a component (here, the minimum thickness of the component to be transferred) is L2, L1 <L2. By being arranged in this way, the transferred rotor member P1 and / or magnet P2 are smoothly guided onto the component support portion 12 while in contact with the inclined surfaces 161 and 162. By this contact, the component pressing portion 16 is lifted upward against the downward urging force. As a result, the rotor member P1 and / or the magnet P2 transferred onto the component support portion 12 are elastically pressed from above by the component pressing portion 16 and are stably held.

The second component supply unit 22 accommodates a plurality of magnets P2 so as to be stacked in the vertical direction, and supplies the magnet P2 onto the component transfer surface 15 at a predetermined timing by a component supply drive unit 54 (FIG. 6) described later. .

<Assembly parts holder>
The assembly component holding unit 40 (an example of a component holding unit) includes a first holding unit 41, a second holding unit 42, a spring 43, and a clamper 45. The first holding part 41 receives an assembly part (for example, the one shown in FIG. 10C) from the raised part support part 12 and elastically holds it from above and below by the spring 43. The second grip portion 42 grips the assembly component from both sides. The clamper 45 moves up and down while holding the assembly rotor from both sides, and transfers the assembly parts to the next process such as the shaft insertion process.

At this time, the rotor member P1 is elastically pressed between the support surface 12a and the component pressing portion 16 described above, so that the rotor member P1 is stably held on the support surface 12a.

  S104: The elevating unit 13 is driven downward by the drive signal from the control device 5 so that the upper surface of the uppermost rotor member P1 supported by the component support unit 12 and the component transfer surface 15 are substantially flush with each other. At this time, as shown in FIG. 8B, the upper surface of the rotor member P <b> 1 is substantially flush with the component transfer surface 15.

Means that

  S 105: The second component supply unit 22 is driven by the drive signal from the control device 5 to supply the magnet P 2 on the component transfer surface 15.

  S106: The second component transfer unit 32 is driven by the drive signal from the control device 5, and the magnet P2 is transferred onto the uppermost rotor member P1 supported by the component support unit 12, and the magnet P2 and the rotor member are transferred. Assemble P1. At this time, since the magnet P <b> 2 transferred by the component pressing portion 16 described above is elastically pressed from above, it is stably held on the component support portion 12.

  S107: In response to the drive signal from the control device 5, the elevating unit 13 is driven downward to make the upper surface of the uppermost magnet P2 supported by the component support unit 12 and the component transfer surface 15 substantially flush.

  S108: The first component supply unit 21 is driven by the drive signal from the control device 5 to supply the rotor member P1 onto the component transfer surface 15.

  S109: The first component transfer unit 31 is driven by the drive signal from the control device 5 to transfer the rotor member P1 onto the uppermost magnet P2 supported by the component support unit 12, and the rotor member P1 and magnet Assemble P2. At this time, the transferred rotor member P <b> 1 is elastically pressed from above by the above-described component pressing portion 16, and is thus stably held on the component support portion 12.

  S110: The control device 5 determines whether the assembly is completed. In this embodiment, for example, the assembly in which the rotor member P1 and the magnet P2 are vertically stacked is continued until the assembly component in the state shown in FIG. When the assembly is completed, the process proceeds to step S111, and when the assembly is not completed, the process returns to step S104.

  S111: The elevator 13 is driven up by the drive signal from the control device 5, and the assembly component is transferred to the assembly component holding unit 40.

  S112: The assembly component holding unit 40 drives a predetermined drive unit (not shown) by a drive signal from the control device 5, and holds the assembly component.

  Thereafter, the assembly component is transferred to the next process such as shaft insertion.

  The operation procedure of the component assembling apparatus 1 is not limited to that shown in FIG. It is also possible to change a part thereof within the scope of the present embodiment. For example, the operation of first supplying the component by the first component supply unit 21 (step S102) is an operation of making the component transfer surface 15 and the support surface 12a substantially flush with each other by the vertical movement of the component support unit 12 by the elevating unit 13. It may be executed before (Step S101) or may be executed in parallel. Similarly, the operation of supplying components by the second component supply unit 22 and the first component supply unit 21 (steps S105 and S108) is performed by the vertical movement of the component support unit 12 by the lifting unit 13 and the component transfer surface 15 and the component support unit. 12 may be executed before the operation (steps S104 and S107) of making the upper surface of the component supported on the surface approximately flush with each other, or may be executed in parallel.
