[0071]
Thereby, the harness 100 (refer FIG. 3) by which the 1st and 2nd connectors 12 and 13 are press-contacted to the both ends of the electric wire 11 is manufactured.
[0072]
The first pressure contact connector 12 and the second pressure contact connector 13 are moved from the first and second parts feeders 30 and 32 (see FIG. 1) to the pressure contact position 53 via the first and second connector supply conveyors 31 and 33. Supplied.
[0073]
Next, the case where the second press-connecting connector 13 is pressed against one end of the electric wire 11 and the other end is stripped will be described with reference to FIGS. 19 to 30.
[0074]
In this case, first, as shown in FIG. 19, the front and rear rails 60 and 61 are moved forward, and the front end of the front rail 60 is disposed at a position where it substantially contacts the end of the wire rail 90 in the wire cutting means 19. . And the front-end | tip of the electric wire 11 is sent to the front-rear rails 60 and 61 side.
[0075]
Next, as shown in FIG. 20, the front and rear rails 60 and 61 are retracted to the tip alignment position. Subsequently, the tips of the plurality of electric wires 11 are aligned in a row by the slide portion 69 of the tip aligning means 68. Thereafter, the electric wire pressing portion 63 is lowered, and the end portion of the electric wire 11 is clamped by the front rail 60 and the electric wire pressing portion 63.
[0076]
Next, with the electric wire 11 clamped, the front and rear rails 60 and 61 are retracted to the strip position B1.
[0077]
Subsequently, as shown in FIG. 21, the rear rail 61 moves backward with the front rail 60 remaining. Thereby, the opening 77 of the front rail 60 is opened.
[0078]
Next, the covering portion cutting means 62 moves up through the opening 77 of the front rail 60. Then, the upper blade 71 of the covering section cutting means 62 is disposed on the upper side of the conveyance path of the electric wire 11, and the lower blade 72 is disposed on the lower side of the conveyance path of the electric wire 11.
[0079]
Next, as shown in FIG. 22, the front and rear rails 60 and 61 move rearward with the electric wire 11 clamped. Thereby, the front-end | tip part of the electric wire 11 is inserted between the upper and lower blades 71 and 72 relatively. And the upper blade 71 and the lower blade 72 are arrange | positioned in the position which entered only the predetermined dimension from the front-end | tip of the electric wire 11. FIG.
[0080]
Next, as shown in FIG. 23, the upper blade 71 and the lower blade 72 move up and down. And as shown in FIG. 23, the upper blade 71 and the lower blade 72 cut | disconnect only the coating | coated part 11a of the electric wire 11, and stop just before biting into the core wire 11b. As a result, a notch 11c is formed in the covering portion 11a of the electric wire 11.
[0081]
In addition, as shown in FIG. 24, V-shaped concave grooves 71a and 72a are formed in the cutting edges of the upper blade 71 and the lower blade 72. Thus, only the covering portion 11a can be cut without damaging the core wire 11b of the electric wire 11.
[0082]
After cutting the covering portion 11a of the electric wire 11, the front and rear rails 60 and 61 move forward in a state where the electric wire 11 is clamped as shown in FIG. If it does so, the front-end | tip part of the electric wire 11 will also move ahead.
[0083]
At this time, as shown in FIG. 26, since the upper blade 71 and the lower blade 72 are still biting into the covering portion 11a of the electric wire 11, the portions ahead of the notch 11c of the covering portion 11a are the upper blade 71 and the lower blade 72. The core wire 11a moves forward only while remaining in its original position.
[0084]
Thereby, the coating | coated part 11a of a front-end | tip is extracted from the core wire 11b. And the front-end | tip part of the core wire 11b is exposed only the length L. FIG. This completes the strip process.
[0085]
When cutting the covering portion 11a of the wire 11, the front end portion of the wire 11 is clamped by the front rail 60 and the wire pressing portion 63 on the front side of the upper and lower blades 71, 72 of the covering portion cutting means 62 as described above ( (See FIG. 21).
[0086]
In this state, by moving the front rail 60 rearward from the upper and lower blades 71 and 72, the positional relationship between the upper blade 71 and the lower blade 72 and the electric wire 11, that is, the cutting position of the covering portion 11a is adjusted. Thereby, the clamp length L can be adjusted.
[0087]
That is, the front rail 60, the electric wire pressing portion 63, the servo motor 64, and the ball screw 65 are configured as a strip length adjusting means, and the strip length L of the electric wire 11 can be freely adjusted.
[0088]
In this way, after the strip processing at one end of the electric wire 11 is completed, the second press-connecting connector 13 is pressed into the other end of the electric wire 11.
[0089]
In this case, first, as shown in FIG. 27, the wire pressing portion 63 is raised, and the clamp of the wire 11 is released. Next, the length measuring means 18 reverses, and the electric wire 11 is sent forward and detached from the front and rear rails 60 and 61.
[0090]
Next, the covering section cutting means 62 descends, and the rear rail 61 moves forward and is accommodated in the front rail 60.
[0091]
Next, as shown in FIG. 28, the length measuring means 18 sends the electric wire 11 backward (to the front and rear rails 60 and 61 side) by a predetermined dimension. Subsequently, the electric wire 11 is clamped by the second electric wire clamping means 47 of the transfer 26. Next, the upper and lower cutting blades 91 and 92 of the electric wire cutting means 19 move up and down, and the electric wire 11 is cut.
[0092]
Next, as shown in FIG. 29, the timing belt 50 of the transfer 26 is rotated by the servo motor 51, and the second electric wire clamping means 47 moves from the length measurement / strip position 52 to the pressure contact position 53.
[0093]
Subsequently, as shown in FIG. 30, the second press contact connector 15 presses the second press contact connector 13 to the end of the electric wire 11 that is not stripped. Thus, the harness 101 (see FIG. 4) in which one end is stripped and the second press-connecting connector 13 is press-contacted to the other end is manufactured.
[0094]
Thus, in the present invention, the covering section cutting means 62 of the aligning and stripping means 17 is disposed so as to be able to enter and retreat to the strip position, so that one set of the first pressure contact means 14 is removed as in the prior art. There is no need to perform operations such as replacement with a means, or replacement of a part of the first pressure contact means 14 to remodel the strip means.
[0095]
This eliminates the need for an exchange-only loading / unloading device. Further, there is no need for alignment, replacement of electrical wiring to the strip means 17, air piping, and the like, and a general operator can easily switch by operating an operation panel or the like without relying on a skilled engineer.
[0096]
Moreover, since it is not necessary to make fine adjustments after switching, the performance of the pressure welding apparatus 1 is stabilized and the operating efficiency is improved.
[0097]
Moreover, the position of the cutting blade which cut | disconnects the coating | coated part 11a of the electric wire 11 was fixed in the conventional strip apparatus. For this reason, when the strip length L is changed, it is necessary to change the cutting blade to another position each time, or to replace the spacer sandwiched between the cutting blade and the holding portion. For this reason, the conventional strip apparatus cannot quickly respond to the change in the strip length.
[0098]
On the other hand, the present invention clamps the front end portion of the electric wire 11 with the front rail 60 and the electric wire pressing portion 63 and moves the front rail 60, so that the upper and lower blades 71 and 72 of the covering portion cutting means 62 are connected to the electric wire. 11 is arranged inside the tip.
[0099]
Therefore, since the clamp length L can be adjusted by adjusting the moving dimension of the front rail 60, the strip length can be specified from the operation panel. In addition, since the front rail 60 is moved by the servo motor 64, the accuracy of the strip length L is improved, and the quality of the harnesses 100 and 101 can be stabilized.
[0100]
In addition, when the pitches at both ends of the plurality of electric wires 11 are different from each other, the tip shape of the wire with the larger pitch becomes convex as it is, and the tip shape of the wire with the narrower pitch becomes concave.
[0101]
Therefore, conventionally, the tips are aligned in a line by cutting the tip of the electric wire with a linear cutting blade. However, the conventional method has a problem in that there are more items to be monitored and checked during operation such as checking the wear state of the cutting blade and checking the cutting state of the electric wire.
[0102]
On the other hand, in the present invention, the wire 11 is temporarily fed beyond a predetermined position, and the tip of the wire 11 is pushed back by the slide portion 69 of the tip aligning means 68, thereby aligning the tip of the wire 11 in a straight line. Therefore, the tip alignment can be performed without cutting the tip of the electric wire 11.
[0103]
Therefore, a cutting blade for aligning the electric wires 11 is not necessary, and therefore, it is not necessary to replace the cutting blade, and the operation efficiency is improved. In addition, it is possible to prevent an increase in the monitoring confirmation items in the above operation.
[0104]
【The invention's effect】
In the present invention, a pair of pressure contact means and a strip means are provided, and a strip means can be used instead of one of the pressure contact means. Therefore, there is a dedicated loading / unloading device for switching between the pressure contact means and the strip means as in the prior art. This is unnecessary and improves the operating efficiency of the apparatus.
[0105]
Further, after switching between the pressure contact means and the strip, it is not necessary to replace the electric wiring and the air piping to the strip means, and the fine adjustment performed before the start of operation can be minimized.
[0106]
Therefore, the time required for the switching operation can be shortened and the performance of the pressure welding apparatus can be stabilized.
