Further, a jacket C is disposed on one of the fixing members that has not been cut, and if the formed fixing member is cut, the jacket C feeds the formed fixing member to perform a joining operation. The jacket C absorbs the formed fixing member by applying a vacuum pressure.

8 to FIG. 11 are schematic views showing a forming process and a cutting process performed by a forming/cutting unit of a fixing component supply module of a fixing component joining device according to a preferred embodiment of the present invention.

8 is a view showing a state in which the cutting process of the fixing member by the cutting portion 114 of the cutter 110 is started after the moving block 66 supplies the wound copper wire 58, in which state the wound copper wire 58 is pressed by the pressing member. 104 formed. The forming projection 108 at the pressing member 104 is engaged with a forming recess 79 located at a lower portion of the forming die 78. Accordingly, the wound copper wire 58 is shaped into the shape of a fixing member. As shown in FIG. 6, the striking member 104 is supported by a striking spring 102 located below the striking member 104. Even if the ascending cam 86 actuates the ascending drive unit 100 to rise, the upper portion of the striking member 104 is still supported by the forming die 78 without further ascending, but the striking spring 102 remains Further compressed. Accordingly, the wound copper wire 58 can be formed more firmly. However, even when the ascending operation of the pressing member 104 is stopped, the cutter 110 continues to rise. The cutting portion 114 of the cutter 110, while rising, also cuts a portion of the fully formed fixing element.

Fig. 9 shows a state in which the drive link member 98 actuates the moving block 66 to move rearward, but at this time the cutter 110 continues to rise to cut the fully formed fixed member and raise it. The drive link element 98 rotates along the axis of rotation 97 and drives the reel 99 to retract the moving block 66 while the driven reel 96 of the drive link element 98 is actuated by the feed cam 88. In this case, since the solenoid 74 is not actuated and one end of the wound copper wire 58 is engaged between the pressing member 104 and the forming die 78, the wound copper wire 58 does not move. When the cutter 110 is raised, the fully formed fixing member is cut by the cutting portion 114. When the cutting portion 114 ascends, the jacket C also rises.

Fig. 10 shows a state in which the winding copper wire 58 starts to be fed when the moving block 66 starts moving forward, in which state the pressing member 104 and the cutter 110 are lowered. In this case, when the optical sensor 94 is interrupted by the optical sensing interrupter 90, the solenoid 74 is actuated. Accordingly, the pressing block 77 located below the solenoid 74 presses the upper portion of the wound copper wire 58. When the driven reel 96 of the drive link element 98 is lowered, the drive reel 99 no longer supports the moving block 66 and the support spring 70 actuates the moving block 66 to move forward. Therefore, the wound copper wire 58 moves forward together with the moving block 66. In this case, when the ascending driving portion 100 coupled to the ascending cam 86 is lowered, the striking member 104 moves downward together with the cutter 110.

Figure 11 shows the arrival of the crimping member 104 and the cutter 110 to the wound copper wire. Before one of the directions 58, the moving block 66 is completely forward and briefly moved. When the driven reel 96 is further moved downward from the state shown in Fig. 10, the moving block 66 is moved forward, and the wound copper wire 58 is completely fed accordingly. When the cutting portion 92 of the optical sensing interrupting plate 90 starts to be positioned between the light emitting portion and the light receiving portion of the optical sensor 94, one of the actuators of the solenoid 74 is stopped. The portion of the wound copper wire 58 that is completely shaped into a fixed element shape has been moved to a portion of the cutter 110, and the unformed portion of the wound copper wire 58 is located on one of the portions of the crushing member 104.

When the states shown in Figs. 8 to 11 are sequentially performed, the wound copper wire 58 is continuously formed and is initially cut into the shape of a fixing member.

Figure 12 is a cross-sectional view showing a punch cutter of a forming/cutting unit of a fixing member supply module of a fixing member engaging device according to another preferred embodiment of the present invention.

In Fig. 6, the pressing member 104 and the cutter 110 are separately provided, but in Fig. 12, a pressing member is integrated with a cutter to become a pressing cutter 120. The crushing cutter 120 is driven by the ascending driving portion 100 and has a forming protrusion 122 and a cutting portion 124. The forming protrusion 122 and the cutting portion 124 are located on one of the pressing cutters 120 and both of them. There is a gap between them. When the crushing cutter 120 is raised, the cutting portion 124 cuts the portion of the wound copper wire 58 that is shaped into the shape of the fixing member, and then, if the crushing cutter 120 is further raised, the forming projection 122 forms the wound copper wire 58 into The shape of the fixing element.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or variations to the spirit and scope of the invention are It should be included in the scope of the patent application attached.
