Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal strip cutting device and a terminal mounting device using the same.

[0002]

2. Description of the Related Art In recent years, the applicant of the present invention has developed a new connection technique for a wire harness in order to meet the demand for downsizing and cost reduction of the wire harness.

FIG. 1 is a perspective view showing a schematic structure of a terminal strip developed by the present applicant.

Referring to FIG. 1, the terminal strip B is formed by bending a conductive metal material with a press, and
0 and a carrier 31 carrying the terminal 30.

The carrier 31 is a strip-shaped member which is undulated in a waveform at a constant pitch interval shown by P in FIG.

The terminals 30 are provided so as to project from the carrier 31 at each valley portion of the carrier 31 in a direction orthogonal to the longitudinal direction of the carrier 31, and are arranged in parallel along the longitudinal direction of the carrier 31. In the terminal 30, a barrel portion 32 that is crimped to the covering portion of the electric wire W, a pair of pressure contact portions 33 (an example of an electric wire connecting portion) that bites into the covering portion of the electric wire W and connects to the inner core wire, and a mating terminal Square tube-shaped connecting portion 34 connected to
And are provided in this order from the base end side. Moreover, the connection part 3
A tab-shaped joint portion 35 is extended at the tip of the No. 4. A part of the joint portion 35 is cut as necessary.

Each of the terminals 30 is cut from the terminal strip B to a preset number of terminals by cutting the carrier 31 from the portion indicated by the phantom line A in FIG. Since the plurality of cut terminals 30 may be mounted in the same connector housing, in this case, the top 31a of the uncut carrier 31 may be completely removed in order to ensure insulation between the individual terminals. It is required that the cut end 31b of the carrier 31 be lower than the top 31a so that the carrier 31 is cut off, as shown by h in FIG.

[0008]

In order to apply the above-mentioned terminal 30 to an automatic wire harness production apparatus, the carrier is so arranged that a preset number of terminals 30 are disconnected from the state of the terminal strip B. It is required to cut 31 accurately. In addition, the cutting work of the carrier 31
So that it can be synchronized with the operation of other automated units,
It needs to be done quickly.

However, since the carrier 31 has a corrugated shape, it is not always easy to accurately and quickly cut a specific portion thereof.

Since the carrier 31 is deformed into a waveform,
In order to cut a specific part, it is dimensionally difficult to introduce the cutting unit from the radial direction of the terminal 30, and
The carrier 3 is arranged in the direction orthogonal to the direction in which the terminals 30 are arranged in parallel
When 1 is pressed, the top 31a of the carrier 31 cannot be completely removed, and reliable insulation cannot be ensured. It is also conceivable to grind the top portion 31a, but in that case, the processing time becomes long and the processing of the cutting powder becomes a problem.

The present invention has been made in view of the above problems, and is capable of precisely and quickly cutting a terminal strip provided with a carrier that undulates in a wave pattern at a constant pitch interval, thereby contributing to automation. An object is to provide a cutting device and a terminal mounting device using the cutting device.

[0012]

The feeding unit that feeds the terminal strip guided along the transport guide unit and the cutting point of the carrier of the terminal strip fed to the feeding unit to the preset terminal cutting position. A terminal pressing unit for locking, and a carrier cutting unit for shearing the above cutting point of the terminal strip locked by the terminal pressing unit in the longitudinal direction of the terminal. It is a terminal strip cutting device to.

According to the present invention, when cutting a carrier that undulates in a corrugated shape at a constant pitch interval, a carrier cutting unit that shears the cutting points of the carrier along the longitudinal direction of the terminal is provided. The motion allows cutting of the standing portion, including the top of the carrier. Further, since the cutting unit for shearing the cutting points of the carrier is provided along the longitudinal direction of the terminals, the cutting points can be quickly and precisely cut even if the terminal strip has a narrow pitch interval. As a result, even when the present invention is incorporated into an automatic wire harness manufacturing apparatus, it is possible to quickly supply terminals in synchronization with other automatic processing elements.

Another aspect of the present invention is a terminal feeding mechanism for feeding a terminal strip to the carrier cutting unit at each pitch of the terminals, and a terminal feeding mechanism arranged upstream of the carrier cutting unit. And a joint section cutting unit for selectively cutting the tabs of the terminals fed to the mechanism.

According to the present invention, the joint cutting of the terminal can be performed in conjunction with the operation of feeding the terminal strip by pitch by the terminal feeding mechanism. Therefore, the terminals can be processed more quickly and intensively. Further, since the joint cutting unit is provided on the upstream side of the cutting unit that cuts the carrier of the terminal strip, the joint cutting unit cuts the tab of the terminal before the terminal is cut from the terminal strip. It will be. Therefore, positioning and the like are easier than in the case where the terminals are cut into pieces, and the tabs can be cut with a simpler mechanism.

Another aspect of the present invention is a terminal mounting device using the above terminal strip cutting device, wherein the terminal strip cutting device, a pallet for detachably accommodating a plurality of terminals, and a terminal of a transport guide unit. A pallet conveyor which is arranged in parallel with the belt conveying direction and reciprocates the pallet along the terminal belt conveying direction, and a terminal cut by the terminal cutting device on the pallet conveyed to the pallet conveyor along its longitudinal direction. A terminal mounting device comprising: a sending unit for sending out.

In this aspect, since the cut terminals can be sent to the pallet, it becomes possible to accumulate various kinds of terminals in the pallet and use them for the downstream process. As a result, by arranging multiple types of terminal cutting devices along the pallet conveyor according to the type of terminal and sending out multiple types of terminals to the pallet, automatic terminal production suitable for the production of larger wire harnesses can be performed. Supply is possible.

FIG. 13 is a flow chart showing the operation procedure of each section according to the present embodiment.

Referring to the figure, the terminal band cutting device 10 described above.
In 0, in order to specify the cutting point of the terminal strip B,
The control unit 190 reads the number of terminal band feeds set in advance for cutting the tab (set number Nt) and the number of terminal band feeds set for cutting the carrier (set number Nc) ( Step S1). After that, the control unit 190 drives the feeding unit 140 to feed the terminal strip B (step S2) and counts the number of feedings (step S3). When the counted number of feeds reaches the set number Nt set for cutting the joint portion 35 of the terminal 30 (step S4), the control unit 190 shifts to the cutting operation of the joint portion 35 (step S5). . In this cutting operation, the air cylinder 152 is driven and the cutting blade 154 moves the base plate 12
The joint portion 35 is cut in cooperation with the fixed cutting unit 155 fixed to 1 (see FIG. 9). If the counted number of feeds does not reach the set number Nt, the control unit 190 bypasses the joint cutting operation of step S5 and proceeds to the next step.

When the joint cutting operation of step S5 is executed or bypassed, the control unit 190 determines whether or not the counted number of feeds reaches the set number Nc set for cutting the carrier 31 of the terminal 30. It is determined whether or not (step S6). If the counted number of feedings reaches the set number Nc, the control unit 190 shifts to the carrier cutting operation (step S7). In this carrier cutting operation, first, the terminal pressing unit 180 operates to press the terminal 30 onto the terminal tray 143, and the terminal 30 is locked. In this state, the cylinder portion 161 is driven to drive the pair of nipper blades 162 and 163 to cut the carrier 31 as shown in FIG. By this cutting operation, the carrier 31 of the terminal strip B is sheared in the axial direction of the terminal 30 while being lowered by a predetermined height shown by h in FIG. As a result, in the transport direction A1, the terminal 30 on the downstream side of the sheared carrier 31 is separated from the terminal strip B on the upstream side and placed on the terminal tray 143.

In step S6, if the counted number of times of feeding does not reach the set number of times Nc, the process returns to step S2 and the above-mentioned work is repeated.

When the carrier cutting process is completed, the control unit 190 shifts to the sending process (step S8).
In this sending step, first, the terminal pressing unit 180
Releases the terminal 30, then the rodless cylinder 171 of the delivery unit 170 is displaced, causing the blade 178 to project forward. By this operation, the delivery portion 178a formed at the free end of the blade 178 delivers each terminal 30 after being cut by the carrier cutting unit 160 from the accommodation chamber of the corresponding terminal tray 143, and the terminal tray 1
The terminals 30 are delivered to the pallet 15 waiting in line with 43.

Then, the above steps are repeated until the processing is completed (step S9).

As described above, in the present embodiment, when cutting the carrier 31 which is undulated in a wave pattern at a constant pitch interval, the carrier which cuts the cutting point of the carrier 31 along the longitudinal direction of the terminal 30 is cut. Since the cutting unit 160 is provided, the standing portion including the top of the carrier 31 can be cut by one cutting operation. Further, the carrier cutting unit 160 is provided with the terminal 3
Since the cutting points of the carrier 31 are sheared along the longitudinal direction of 0, even if the terminal strip B has a narrow pitch interval, the cutting points can be quickly and precisely cut. As a result, even when the present invention is incorporated in an automatic wire harness manufacturing apparatus, the terminal 3 can be quickly synchronized with other automatic processing elements.
It becomes possible to supply 0.

In particular, in the present embodiment, the joint cutting of the terminal 30 can be performed in conjunction with the operation of feeding the terminal strip B by the pitch by the terminal feeding unit 140. Therefore, the processing of the terminal 30 can be performed more quickly and intensively. Further, the joint cutting unit 150 cuts the tab of the terminal 30 before the terminal 30 is cut from the terminal strip B.
Positioning and the like are easier than those in which 0 is cut into pieces, and the tabs can be cut with a simpler mechanism.

Further, in this embodiment, the cut terminal 3 is used.
Since 0 can be sent to the pallet 15, it becomes possible to store various kinds of terminals 30 in the pallet 15 and use them for the downstream process. As a result, a plurality of types of terminal processing devices are arranged along the pallet conveyor 14 according to the type of the terminal, and a large number of types of terminals 30 are sent to the pallet, thereby making the terminal suitable for manufacturing a larger-scale wire harness. 30 automatic feeds are possible.

The above-described embodiment is merely an example of a preferred specific example of the present invention, and the present invention is not limited to the above-described embodiment. It goes without saying that various design changes are possible within the scope of the claims of the present invention.
