  As shown in FIG. 34, when the tool returns, the contact receiving portion 2 and the cutting punch 1 in the direction indicated by the arrow 35 move. However, since the contact 21 does not have the engaging portion 21a, the contact 21 comes out as shown in FIG.

  In this way, if the engaging portion 21a is not provided, the contact may stick to the punch after being temporarily inserted and come back (return), and the conventional method cannot be assembled or the assembly rate is frequently generated and the yield rate is good. Will be reduced.

  As described above, possible causes of the component 21 missing in the contact 21 include Paris after cutting, electrostatic force, vibration of the device, and the like.

  Therefore, as countermeasures against missing parts, there are those shown in FIGS. FIG. 35 is a partial front view showing countermeasures against component omission, FIG. 36 is a partial front view showing countermeasures against component omission in the conventional method, and FIG. 37 is a partial front view showing defects in the conventional method.

  As shown in FIG. 35, the contact 21 is inserted at a position shifted from the center of the housing insertion hole 25a by Ymm as indicated by reference numeral 74, and the contact receiving portion 2 moves in the direction indicated by the arrow 34 as shown in FIG. That is, a method of generating a distance Ymm indicated by reference numeral 75 when OPEN is performed can be considered. However, as shown in FIG. The tip of the component may be deformed, and a defect that scrapes the housing 25 occurs.

The housing 25 in which the specified contact has been inserted is transferred to a housing assembly post-process 50 in a subsequent process.

  Next, an assembly method using the component insertion device according to the first embodiment of the present invention will be described with reference to FIGS.

  FIGS. 4 to 12 are diagrams showing the steps of assembling the parts according to the embodiment of the present invention in order. FIG. 4 shows the origin, FIG. 5 shows the state in which the contact cutting punch has advanced, and the contact receiving portion has advanced. 6 shows the contact clamp and cut, FIG. 7 inserts the contact tip, FIG. 8 returns the minute pitch, FIG. 9 temporarily inserts and fully inserts the temporary insert contact one pin before, FIG. 11 shows the return of each tool, and FIG. 12 shows the housing pitch feed and contact feed, respectively. FIG. 13 is a front view showing the OPEN state of the contact receiving portion according to the embodiment of the present invention, and FIG. 14 is a time chart of each tool of the stitching press-fitting operation.

  Referring to FIGS. 4 to 12, in the component insertion device according to the embodiment of the present invention, a stitching type assembly method in which the contacts 21 are inserted into the housing 25 one pin at a time is employed. The assembly process will be described focusing on the movement of one contact 21.

  Referring to FIG. 4, the continuous strip is held on the cutting die 3 at the origin. On both sides of the contact 21, the cutting punch 1 and the contact receiving portion 2 are in positions facing each other in an open state. A housing 25 is provided on the housing feeding mechanism 11, and a contact 21A is shown in the state where the contact 21 is inserted into the hole 25a of the housing. On the other hand, reference numeral 21B indicates that the contact is temporarily inserted.

  Referring to FIG. 5, the cutting punch 1 of the contact 21 is advanced, and the contact receiving portion 2 is also advanced. The contact 21 that is not held by the continuous strip 20 and is supplied to the separation position by the transport system is clamped in the plate thickness direction by the cutting punch 1 and the contact receiving portion 2 at the position shown in FIG.

  Referring to FIG. 6, the cutting punch 1 and the contact receiving portion 2 simultaneously move in the plate thickness direction of the carrier 22 as indicated by an arrow 34, so that the contact 7 is contacted at the edge portion (cutting portion H) 23 at the contact 21. Is cut and separated from the carrier 22 in a state of sandwiching. At this time, the contact 21 is held by the cutting punch 1 and the contact receiving portion 2.

Incidentally, the present insertion portion 4 for the insertion of the cutting punch 1 contact 21 in the first embodiment at the same time temporarily inserted into Howe di ring 25, the provisionally inserted contact 21 in the previous step to the housing 25 Have. The cutting punch 1 is provided with a main insertion portion 4 so as to protrude from a side surface facing the housing 25, and a temporarily inserted contact 21B temporarily inserted by the distal end surface of the main insertion portion 4 is press-fitted into the insertion hole 25a. This insertion is performed.

  Referring to FIG. 7, the contact 21 is transported to a predetermined position by a predetermined operation of the cutting punch 1 and the contact receiving portion 2, and an insertion hole 25 a in which the tip of the sandwiched contact 21 is an insertion position of the housing 25. Is temporarily inserted.

  Referring to FIG. 8, after the distal end portion of the contact 21 is inserted into the insertion hole 25a of the housing 25, the housing 25 is moved by the housing feed mechanism in the return direction A34, which is reverse to the pitch feed direction B, by a minute pitch Ymm. Returned.

  Referring to the time chart shown in FIG. 14, in the temporary insertion, the tip of the terminal (contact) is inserted into the housing at a point indicated by reference numeral 61, the return movement is completed at reference numeral 62, and the main insertion is performed at reference numeral 63. . Thus, since the operation timing of the terminal tip in the housing reverse return direction Ymm is performed at a high speed, the press-fitting speed is not affected. In other words, there is no tact.

Referring to FIG. 9, down to the cutting punch 1 and the contact receiving portion 2 are both housing 25 side (insertion direction indicated by the arrow C direction 32), provisionally inserted more clamped contact 21 in the lowered indicated by arrow C32 a temporary insertion contact (second contact) 21 Te, which provisional already inserted a contact that is provisionally inserted before cycle process in this insertion portion 4 provided on the side of the housing 25 side of the cutting punch 1 at the same time (the first No.) 21B (FIG. 6) is fully inserted. That is, at this time, the contact 21 (second contact) gripped by the cutting punch 1 and the contact receiving portion 2 is completely temporarily inserted into the insertion hole 25a which is the insertion position of the housing 25 by a predetermined operation. In this state, air suction is performed from the component suction hole 13 provided in the housing feed mechanism 11. The contact 21 (second contact) is sucked by the suction action, and is fixedly held inside the insertion hole 25a of the housing (temporary insertion) .

  Referring to FIG. 10, thereafter, the contact receiving portion 2 moves by a movement amount Zmm in a direction 34 indicated by an arrow A, and the movement of the contact 21 releases the clamp in the plate thickness direction. By this operation, a gap of Y mm is generated between the cutting punch 1 and the contact 21.

  Referring to FIG. 11, when each tool returns, the cutting punch 1 and the contact receiving portion 2 rise in an arrow D direction 35 that is opposite to the insertion direction. At this time, the cutting punch 1 moves in the arrow B direction 33.

  As shown in FIG. 12, the cutting punch 1 and the contact receiving portion 2 return to the origin by the above-described movement. This process is continuously and automatically repeated by the assembling apparatus while moving the housing 25 by one pitch. At this time, the pitch feed amount of the housing is the housing pitch Pmm + the pitch return amount Ymm.

  Further, after the prescribed number of contacts 21 are inserted into the housing 25 and the number of cycle operations is performed, the last one is inserted. At this time, the continuous band member 20 is not fed (not shown, but the feed mechanism uses, for example, a servo motor and a sub rocket), and the cutting punch 1 and the component receiving part 2 do not hold the contact 21. A cycle operation for inserting the contact 21 is performed to complete the product assembly (empty insertion operation). This operation is a so-called empty insertion operation of only the main insertion without a temporary insertion operation.

  Next, the operation of the component insertion method and the assembly apparatus according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 13, the movement amount Zmm is moved in the arrow A direction 34, and the clamp of the contact 21 in the plate thickness direction is released by this movement. By this movement, it becomes possible to generate a gap Ymm between the cutting punch 1 and the contact 21. Since there is a gap Ymm, the cutting punch 1 and the contact receiving portion 2 return to the arrow D direction 35 and perform an operation. However, the contact 21 is not pulled out by the cutting punch 1.

The movement is completed before the terminal book insertion starts.

  After the parts receiver is opened (OPEN), a gap of Y mm is formed between the cutting punch 1 and the contact 21. This eliminates the phenomenon that the contact 21 sticks to the cutting punch 1 when the cutting punch 1 and the contact receiving portion 2 return. Further, in order to maintain the terminal posture at the time of temporary insertion, the contact air suction fixing is performed from the component suction hole 13 provided in the housing feed mechanism 11 on the opposite side of the housing hole 25a.
