Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal mounting for connecting a terminal to an electric wire routed on a board of an insulation plate (hereinafter simply referred to as IP) mounted around a seat of an automobile, for example. About the machine.

[0002]

2. Description of the Related Art As shown in FIG. 27 (a), an electric wire w is provided on both sides of a rectangular substrate W made of resin, as shown in FIG.
Are arranged, and a terminal t as shown in FIG. 27 (b) is press-connected to the electric wire w. Protrusions Wp of various shapes are formed on the surface of the substrate W, and the electric wire w is sandwiched between the protrusions Wp and locked by the frictional force.

In the terminal mounter for producing the IP, the substrate W, on which only the electric wire w has been routed in the previous process, is moved vertically and horizontally in a horizontal plane and sent to a press-contact position, and is provided at the press-contact position. As shown in FIG. 27C, the terminal t is connected by pressure to the electric wire w on the substrate W by a pressure contact mechanism.

[0004]

In the above-mentioned terminal mounting machine, the terminals are pressed against the electric wires routed on the substrate W by moving the substrate W to the pressed position of each terminal. ing.

In this case, the shorter the movement route, the higher the efficiency and the size of the whole apparatus can be reduced, and these are not repaired, which leads to cost reduction.

An object of the present invention is to reduce the size of the terminal mounting machine as described above.

However, as a prerequisite for the mounting machine, in the present invention, a terminal cutting machine for separating a terminal from a terminal hoop introduced from a hoop, a terminal cutting machine which is moved to a press-contact position and placed on a work. It is assumed that the apparatus comprises a press-contacting machine for press-contacting the cable, and a pallet transfer device for supporting the work and moving the work-replacement position and the press-contact position.

[0008]

In order to solve the above-mentioned problems, according to the present invention, first, the above-mentioned transporter sets the pallet to X
It is movable in the Y direction, a plurality of the pressure welding machines are arranged around the square moving area, and the periphery of the moving area corresponding to each pressure welding machine is set as the pressure welding position. Each of the terminal cutting machines was attached, and at least two of the hoops for guiding the terminal hoop to each of the terminal cutting machines were vertically stacked.

[0009] With such a configuration, the pallet is transported in an X, Y direction so as to reach an arbitrary position.
A movement mode (for example, an XY table in an embodiment described later) based on a combination of directions is the simplest device configuration,
In order to contribute to downsizing of the device, it is most effective to reduce the occupied space in a horizontal plane by stacking FOUPURIS.

[0010] At this time, it is preferable that the pallet is provided with a means for pressing the peripheral edge of the work on the pallet so that the work follows the upper surface of the pallet. The work of the resin plate is "warped" as it is manufactured. When pressed against the electric wire on the surface as it is, the terminal and the electric wire are relatively inclined and pressed, so if the degree of “warpage” is excessive, the inclination between the electric wire and the terminal t is large. As a result, the desired “pressing height” cannot be obtained, or the pressing position shifts in a more severe case, but the pressing can correct the “warpage” and prevent the occurrence of such a defect. .

Further, by pressing the work, it is possible to prevent the work from being displaced due to severe vibration at the time of conveyance.

Second, as the terminal cutting machine, a feed roller intermittently rotating in contact with the terminal hoop, and a positioning pin for inserting and locking into the positioning hole of the hoop at every predetermined feed of the terminal hoop, orthogonally to the hoop. , Comprising a punch and a die for cutting each terminal from the terminal hoop, feeding the predetermined amount by the feed roller, positioning the terminal hoop by the pin, and separating the terminal by cooperation of the punch and the die in that state. It was.

With this configuration, an arbitrary feed amount can be set immediately by merely changing the timing of the contact and separation of the pinch roller, without increasing the size of the device as in the case of a cam mechanism. Since insertion and locking are performed in the positioning holes of the hoop from the orthogonal direction, accumulation of errors in the feed amount of the roller can be prevented, and cutting can be performed at an accurate position.

At this time, the feed amount of the feed roller is selectively switched between one terminal and two terminals, and the punch and the die are cut not only at one terminal but also at two terminals at a time. The pressure welding machine has a one-terminal clamping chuck and a two-terminal clamping chuck, and can selectively position both the chucks at the clamping position.

Furthermore, if the punch and the die holder are integrated, there is no need to adjust the clearance between the punch and the die, which saves labor and allows the hoop to be cut while always maintaining the best clearance. The life of the punch and die can be extended.

Third, the terminal cutting machine cuts a terminal by moving a punch toward and away from the die with a terminal hoop interposed between the punch and the die. The reciprocation of the cylinder rod perpendicular to the reciprocation direction is performed by connecting the inclined surfaces.

If the angle between the inclined surface and the traveling direction is set to an acute angle of 45 ° or less, the stroke of the air cylinder for pressing the punch is small even if the punch is given the same work. This also contributes to downsizing of the device.

In the case where the working direction of the punch and the disposing direction of the unit are the same as in the embodiment described later, if the components are arranged so as to increase the occupied space in that direction, the dimensions of the unit will be reduced. Since the total size of the apparatus is increased by accumulation, it is also prevented.

Fourth, the terminal cutting machine according to the second means is applied to the terminal cutting machine according to the first means.

As a fifth means, in the pressure welding machine, a terminal chucking / pressure welding unit is provided on a base so as to be movable in the front-rear direction, and the terminal chuck can be moved up and down to a terminal cutting position by one cylinder. That is, the cylinder can be moved up and down to the terminal press-fitting position by another cylinder.

In a case where the height of the chucking position and the pressure contact position of the terminal is different from each other as in the embodiment described later, the motor can be controlled if the lifting and lowering operation of the chuck is performed by one driving mechanism. When using a motor, the equipment is expensive and the configuration of the apparatus is complicated. Therefore, if two air cylinders having different strokes are used at the chucking position and the pressure contact position, the cost can be reduced and the device configuration can be simplified.

Finally, the pressure welding machine in the first to fourth means is applied to the fifth means.

[0023]

Each basic unit 4 is composed of three sub-units: a hoop feed unit for feeding the hoop H to the chucking position of the terminal t at a pitch, a hoop cutting unit, and a terminal chucking / pressing unit. The details of each subunit will be described later. First, the transport mechanism 100 that transports the work W to the press-contact position corresponding to each basic unit 4 will be described. The transport mechanism 100
An XY table 10 is provided on the middle base plate 2. FIG. 3 shows only the portion of the XY table 10 taken out. In the drawing, the arrow indicated by the symbol Y indicates the front-back direction of the apparatus.

As shown in the figure, a linear guide 11a and a ball screw 11 are disposed in the front-rear direction of the middle base plate 2.

A linear guide 12a and a ball screw 12b that move in the left-right direction (X direction) are provided.

The X table 12 attached to the left-right linear guide 12a is a rectangular plate whose longitudinal direction is directed in the front-rear direction, and the linear guide 13a is also disposed on the upper surface along the longitudinal direction (front-rear direction). Has been established. A pallet 13 on which the work W is placed is attached to the linear guide 13a, and the pallet 13 is guided by the linear guide 13a, and is driven by a ball screw 13b.
It moves along the longitudinal direction of the table 12.

As shown in FIG. 3, the pallet 13 has a two-stage structure in which two plates 14 and 15 are vertically stacked via four shafts 16, and a lower portion is a base portion 14, The upper side is the mounting portion 15 for the work W.

The upper plate 21 of the positioning plate 20 includes
As shown in FIG. 5, a guide member 22 and a pin 23 for positioning the work W are provided.
As shown in FIG. 6, the support member 27 of the electric wire w arranged on the back surface of the work W is fixed by screws from the lower surface of the plate.

As shown in FIG. 5, an opening 24 is provided at a position of the upper plate 21 corresponding to the support member 27. The support member 27 has an upper portion projecting from the opening 24. ing. Here, the role of the support member 27 will be described.

As described above, the electric wire w is routed not only on the front surface but also on the rear surface of the substrate W of the work. At that time, as described above, since the electric wire w is only sandwiched between the ridges Wp on the work surface and is locked by the frictional force, if the terminal t is operated as it is, the electric wire w is separated from the work W. It cannot be pressed.

Therefore, in order to support the electric wire w upward at the pressure contact position, the support member 27 is provided directly below the electric wire w (immediately below the through hole). In this way, the electric wire w on the back surface is supported by the support member 27, and the terminal t can be acted from the front side through the through-hole and press-contacted.

Next, when the terminal is pressed against the work W, the work W is not sent to the pressed position as it is, but in this embodiment, the work W is pressed by the plate as described above. A work pressing mechanism 30 for correcting the "warpage" is provided. Next, the pressing mechanism 3 for this work
0 will be described.

As shown in FIGS. 3 and 7, an air cylinder 31 is provided on the lower base plate 3 immediately below the end point position T ₀ of the pallet 13 of the X table 12. The air cylinder 31 has a rod 31a directed upward, and a support plate 32 is attached to an upper end thereof. Support poles 33 are erected at four positions on the upper surface of the support plate 32 in a rectangular shape. The support poles 33 are provided on the intermediate base plate 2 and the Y table 11 as shown in FIGS. The upper end reaches above the Y table 11 through the through holes 2h and 11h provided.

Here, the holding plate 35 has a structure shown in FIGS.
As shown in FIG. 5, an opening 35a having a similar shape slightly smaller than the outer shape of the work W is provided on the inner side, and when the holding plate 35 comes into contact with the work W, the inner periphery of the opening 35a and the outer periphery of the work W are opened. The inner circumference of the workpiece 35a is located inside the outer circumference of the work W, and the interval between the corresponding sides is equal. That is, the pressing plate 35 presses the work W only in the vicinity of the periphery of the work W. When the terminal t is pressed against the electric wire w near the periphery of the work W, the terminal t
And the pressing plate 35 do not interfere with each other. As described above, the “warpage” of the work W is corrected.

The end point position T ₀ of the pallet 13 of the X table 12 is also the origin position of the XY table 10, and the work W is pressed as described above at this origin position, and X is moved from this origin position as it is. -It moves vertically and horizontally on the Y table 10 to reach a predetermined pressure contact position, and receives pressure contact at each pressure contact position. When all the pressure welding is completed, it returns to this origin position again.

When the pallet 13 returns to the origin position (the state shown in FIG. 10), the flow reverses to the previous one.
The rod 31a of the air cylinder 31, which has caused the holding plate 35 to act on the workpiece W, advances, and pushes up the holding plate 35 against the urging force of the spring 34b. Thus, the pressing of the work W is released (the state of FIG. 9).

Thereafter, the pallet 13 returns to the starting point position S ₀ on the X table 12 (state shown in FIG. 8), and the worker collects the work W to complete one IP. The above is the description of the transport mechanism 100 of the work W in this apparatus.

Next, the basic unit 4 of the press-contact mechanism 200 for pressing the terminal t against the electric wire w on the work W conveyed to the press-contact position by the transfer mechanism 100 will be described. As described above, each basic unit 4 is a hoop feed unit that feeds the hoop H to the chucking position of the terminal t at a pitch,
It is composed of three sub-units, a hoop cutting unit and a terminal chucking / pressure welding unit. Hereinafter, the three subunits will be described individually.

(1) Hoop feed unit The hoop feed unit 40 shown in FIGS. 11 and 12 is guided into the basic unit 4 from the hoop R which is disposed behind the arrangement area of the basic unit 4 in FIG. The hoop H is moved by pitch feed to a chucking position of a terminal chucking / pressing unit described later.

As shown in FIGS. 11 and 12, a vertical stand 41s is erected on a base plate 50p of the unit 40, and a servo motor 42 having a main shaft directed vertically downward is provided on the stand 41s. It is attached at a side portion of the bearing box 43 of 42a. A main roller 41 for feeding a hoop is attached to a lower end of a vertical rotation shaft 42b connected to the main shaft. Main roller 4
1 rotates constantly during operation of the apparatus.

On the other hand, as shown in FIG.
A horizontal plate 43h protrudes next to the bearing box 43 in s, and a linear guide 44 is disposed on the lower surface of the horizontal plate 43h. The linear guide 44 has a bracket 4
A pinch roller 46 (rotating shaft) is vertically provided via 4a, and a dog 45d connected to a rod 45a of a thin air cylinder 45 fixed to the bearing box 43 is connected to the bracket 44a. I have.

With this configuration, the pinch roller 46 is driven by the thin air cylinder 45 so as to be able to come in contact with and separate from the main roller 41. Feed pitch every time.

The "unit terminal" for pitch feeding is as follows.
There are two types of terminals, a single-pole terminal t of the basic shape itself shown in FIG. 27 (b) and a two-pole terminal T in which the one-pole terminal t is continuous in the width direction. The feed amount is twice as large as that in the case of the single pole terminal t.

The high-precision feeding of the hoop H can be realized by the pitch feeding of the hoop H by the main roller 41 and the pinch roller 46 driven by the servo motor 42 having the speed reducer (42a). The device does not become complicated or large unlike the cam mechanism.

The hoop H, which has been pitch-fed to the chucking position by the hoop feeding unit 40 as described above, is cut by the hoop cutting unit 50, and the terminal for each unit (one pole t and two poles T as described above) is used. There are two types of units). Next, the hoop cutting unit 5
0 will be explained.

(2) Hoop cutting unit 50 The hoop cutting unit 50 shown in FIGS. 13 to 16 (and FIGS. 11 and 12) is disposed downstream of the hoop feed unit 40 in the hoop H feeding direction. And a cutting mechanism 51 for positioning the hoop H at a predetermined cutting position during cutting. Both mechanisms 51 and 61 are provided on the base plate 50b of the hoop feed unit 40.

The hoop cutting mechanism 51 has a pair of punches 52 and a die 58, and the punches 52 are disposed orthogonal to the hoop H feeding direction as shown in FIG.

At the rear end of the punch 52, a front end of a strip-shaped wedge 54 disposed at a right angle to the operation direction is located, and behind the wedge 54, as shown in FIG.
An air cylinder 53 is arranged in parallel with the wedge 54.

As shown in FIGS. 14 and 15,
Below the punch 52, a guide mechanism for guiding the forward / backward movement is provided. This guide mechanism has a pair of stripper bolts 55, 55 arranged in line with the axis of the punch 52 in a horizontal plane below the punch 52. The stripper bolt 55 has a threaded portion 55b at the rear end thereof.
Is screwed to and connected to a lower portion of a dog 52d attached to a rear portion of the die holder 59, and is supported by being inserted through a bearing 57 embedded in a base block 56 halfway in the longitudinal direction. It is in contact with the wall.
A compression spring 55s is mounted on the stepped small diameter portion at the rear of the stripper bolt 55, and urges the punch 52 rearward between the dog 52d and the stepped portion. Thus, the punch 52 is guided and guided by the guide mechanism via the wedge 54 by the driving of the air cylinder 53 and moves forward and backward.

As described above, the punch 52 is not advanced and retracted by the air cylinder disposed on the axis concentric with the axis of the punch 52. Instead, the inclined surface of the rear end of the punch 52 and the inclined surface of the wedge 54 are connected. The reason is that, when the air cylinder 53 is to be arranged concentrically with the axis of the punch 52, the axial direction is the juxtaposition direction of the basic unit 4, and the component arrangement that takes up a large occupied space in that direction is required. Doing so accumulates the dimensions of the four basic units and increases the size of the entire device.
To avoid it.

In addition, this inclined surface coupling not only prevents the device from being enlarged due to the arrangement direction of the air cylinder 53 described above, but also allows the inclination angle θ of the wedge 54 to be kept at an acute angle of 45 ° or less. For example, the stroke of the air cylinder 53 for pressing the wedge 54 to give the same work to the punch 52 may be small, which also contributes to downsizing of the apparatus.

As shown in FIGS. 13 to 15, the die 58 disposed opposite to the punch 52 is cylindrical and fixed to the die holder 59, and the edge of the punch 52 has an edge on the punch side. A cutting blade hole 58h to be fitted is provided. The rear end is connected to a pipe 60, and a cut piece generated at the time of cutting is sucked from the cutting blade hole 58h through the pipe 60 by a blower (not shown) and discharged out of the apparatus.

Here, the die holder 59 to which the die 58 is fixed is integrated with a base block 56 in which a bearing 57 for guiding the punch 52 to move forward and backward is embedded. Since the positional relationship is fixed, there is no need to adjust the clearance between the punch 52 and the die 58 each time, and it is possible to save labor and cut the hoop while always maintaining the best clearance. The life of the die 52 and the die 58 can be extended. The above is the hoop cutting mechanism 5
1, adjacent to the hoop positioning mechanism 61
Is provided.

The hoop positioning mechanism 61 is shown in FIGS.
As shown in FIGS. 5 and 16, a pin holder 62 having a positioning pin 62p attached in the longitudinal direction of the longitudinal rectangular member is disposed in parallel with the punch 52. Pin holder 62
As shown in FIG. 15, is fitted in a groove provided continuously with the base block 56 and the die holder 59, and is slidable along this groove.

As shown in FIG. 16, a short rod air cylinder 63 is provided immediately above the front part of the pin holder 62, and a bracket 63 attached to the rod 63a is provided.
The tip of the pin holder 62 is attached to one end of the pin b. The other end of the bracket 63b is a pin holder 6
Guide shaft 64 and guide cylinder 6 provided in parallel to
A 4 g guide mechanism is connected to the tip of its guide shaft 64.

With this configuration, when the hoop H flows to the cutting position (chucking position), the air cylinder 6
3, the pin holder 62 advances, and the positioning pin 62p is inserted into the positioning hole of the hoop H to position the hoop H. Thereby, the accumulated error of the feed amount by the hoop feed unit 40 can be eliminated.

In this case, as shown in FIG. 16, the air cylinder 63 for moving the pin holder 62 forward and backward is disposed above the front portion of the pin holder 62, so that the cylinder 63 and the pin holder 62 can be seen in plan view. Are overlapped to reduce the size of the device.

In addition to the positioning of the hoop H in the feed direction by the positioning pins 62p, a pressing mechanism is provided for suppressing the vertical swing generated when the hoop H is stopped.

As shown in FIG. 16, this mechanism has an air cylinder 66 disposed immediately above the hoop H at a position where the positioning pin 62p exists. The air cylinder 66 is connected to the hoop feed unit 4 of the stand 41s.
The rod 66a is attached to the opposite side of the surface on which the 0 main roller 41 is attached, and the pressing member 67 is attached to the tip of the rod 66a via a bracket 66b.

The hoop H is at the cutting position (chucking position)
The air cylinder 66 operates at the same timing as the positioning operation by the positioning pin 62p, and the pressing member 67 presses the hoop H from above to position the hoop H in the vertical direction.

As shown in FIG. 5, a rotation mechanism 80 is provided around the extension axis of the chuck 90 (around the vertical axis), and when the terminal 90 is pressed against an object in which the posture of the terminal t with respect to the electric wire w differs by 90 ° around the vertical axis, The rotation mechanism 80 acts to rotate the chuck 90 by 90 ° around the vertical axis to press the chuck 90 against each other. The rotation mechanism 80 will be described.

A mounting rod 7 is provided on the lower surface of the plate 75.
5b is provided vertically, and a cylindrical bearing 81 is attached to the lower end thereof. A ball spline 82 is provided in the bearing 81, and a rotating body 83 is fixed to an upper portion of the cylindrical portion of the ball spline 82. The extension shaft 77 is inserted through the ball spline 82, and the extension shaft 77 is attached to a lower end of the ball spline 82 at the lower end thereof.
7, a chuck 90 is detachably attached.

Further, as shown in FIG.
The upper edge protrudes horizontally, and the overhang portion 81h
The fourth air cylinder 84 is horizontally disposed. The axis of the rod 84a is disposed on a line eccentric from the axis center of the extension shaft 77 (the rotation center of the chuck 90), and the tip of the rod 84a is
The arm 83a of the rotating body 83 above the column is swingably connected. Therefore, when the rod 84a moves forward and backward, the arm 83a is pushed and pulled, and the rotating body 83 rotates, so that the lower chuck 90 rotates. The fourth air cylinder 84 has its rear end rotatably mounted on a vertical axis because the cylinder axis of the fourth air cylinder 84 swings in a horizontal plane by pressing the rotating body 83.

A stopper 85 is mounted on the bottom surface of the cylindrical portion of the ball spline 82. As shown in FIG. 22, the stopper 85 has a cylindrical shape extending along the circumferential direction.
A part of a predetermined distance from the peripheral surface toward the center side has a hollow shape over a range of 70 °, and rotates around the extension shaft 77 together with the rotating body 83. A pair of dampers 86 are provided at a 180 ° opposing angle in the middle of the rotation path of the surface facing the circumferential direction of the hollowed portion. One of the opposing surfaces of the damper 86 and the stopper 85 comes into contact with one of the dampers 86 when the rod 84a of the air cylinder 84 advances most and retreats, respectively. In addition, the chuck 90 rotates around the extension shaft 77 and absorbs an impact when the chuck 90 stops. The above is the configuration and operation of the movement and rotation mechanism of the chuck 90 of the terminal chucking / pressing unit 71. Next, the structure of the chuck 90 will be described.

As shown in FIG. 23, the chuck 90 has an upper plate 91a and a pair of opposing plates 91b, 91b suspended therefrom.
A holding plate 93 is attached to a horizontal shaft 92 which is passed between the facing plates 91b, 91b of a housing portion 91 composed of a housing plate 91 (to be collectively referred to as a facing plate 91b). The main body 94 (when distinction is made between one pole terminal and two pole terminals, 94a and 94
b) are attached such that their longitudinal directions are orthogonal to each other.

A gear 92a is mounted on the horizontal shaft 92, and a main gear 9 for driving the gear 92a is mounted on the gear 92a.
2m is engaged. The main gear 92m is attached to a main shaft 95a of a rotary actuator 95 attached to a plate on the near side of the opposed plate 91b in the drawing, and driven by the rotary actuator 95, the gear 92m,
The holding plate 93 is rotated by 90 ° via the pin 92a. As a result, as shown in FIG.
Two chuck bodies 94a, 94 attached thereto
One of the terminals b faces the vertical direction, the other faces the horizontal direction, and grips the terminal t in the direction facing the vertical direction.

The upper plate 91a of the housing portion 91
, Two bolts 96, 96 are screwed together with the head projecting from the lower surface of the plate, and the head serves as a "hit" for rotation of the holding plate 93, and the amount of rotation is small. Adjustment is possible. Next, the structure of the chuck body 94 will be described with reference to FIGS. FIG. 24 shows the chuck 94b for a bipolar terminal, but the basic structure is the same for a single pole and a bipolar pole.

As shown in FIG. 24, the chuck main body 94 has a substantially rectangular shape, and the lower portion thereof has a shape narrowing downward as shown in the front view of FIG. A stepped cylindrical mounting portion 97 for mounting to the holding plate 93 protrudes from the upper surface, and a gripping plate 98 for chucking the terminal t is provided at the center of the front surface. The holding plate 98 is fitted in the front groove 94c,
4c, it is swingably attached to a horizontal shaft 99 disposed in the width direction of the groove 94c (left and right direction in FIG.
As shown in (b), the compression spring 98 is buried at the upper end side.
The lower end is urged clockwise in the figure by b.

A spacer 98b is fixed to the lower portion of the main body 94 by screws, and a groove 94g for terminal fitting is provided on a surface of the main body 94 facing the lower end of the spacer 98b. A hole 98h is provided in a portion that covers the groove 94g, and when the terminal T is chucked, the terminal T is relatively fitted into the groove 94g, and the gripping plate is urged by the spring 98s. The holding portion 98p at the lower end of the 98 presses the terminal T toward the main body through the hole 98h to chuck.

With this gripping method, when the terminal T is pressed against the wire w and then pulled out from the chuck 90, the gripping force (spring pressure) of the terminal T is greater than the gripping force (spring pressure). Since the force applied to the substrate W is much greater, the terminal T is connected to the electric wire w while the chuck 90 is connected.
Easily pulled out of

FIG. 25 is a cross-sectional view showing the chucking of the terminals t and T in the chuck body 94. In the case of the two-pole chuck body 94b, as shown in FIG. There are two holes 98h into which the heads are fitted, and the one in which the gripping plate 98 has one pole is also integrated with the groove 94c at an axial distance. On the other hand, the chuck body 94a for one pole has only one hole 98h as shown in FIG.

The chuck main body 94 is configured such that the mounting portion 97 is attached to the mounting hole 93 formed in the holding plate 93.
h and is attached by screwing (screw 97b), and the whole is attached to the lower end of the extension shaft 77 by screwing. The above is the configuration of the terminal chucking / pressure contact unit 71. Next, the operation will be described.

First, the terminal t is moved by the hoop feed mechanism.
When hoop H is sent to chucking position C ₁ of
As shown in FIG. 19, the chuck 90 first air cylinder 72 is operated to chuck the standby position (home position) terminal t of the unit is lowered from C ₀ right above the terminal chucking position C _1.

Immediately after the chucking, the hoop positioning mechanism 61 and the cutting mechanism 51 operate to cut the hoop H and separate the unit terminal t.

When the terminal t is disconnected, the chuck 90 has already chucked the terminal t, so that the first air cylinder 72 operates immediately and the chucking standby position C _0.
Retreat (rise) until.

[0091] Subsequently, as shown in FIGS. 19 20, the chuck 90 is waiting position pressed horizontally moved by being driven by a third air cylinder 74 remains in the height of the waiting position C ₀ of the chucking After reaching P ₀ , subsequently, as shown in FIG. 20, it is driven by the first and second air cylinders 72 and 73 and descends, and at its bottom dead center P ₁ (pressure contact position), the terminal t of the unit is reached.
Is pressed against the electric wire w on the work W.

[0092] When the pressure is over, the chuck 90 is first again, it is driven to the second air cylinders 72, 73 retracted to the standby position P ₀ of the pressure (increase), followed by the third remains in its height retracts be driven to the air cylinder 74 returns to the standby position (home position) C ₀ chucking.

[0093] Thus, pressure operation of one terminal t is completed, waiting on its original position C ₀ in chucking the next terminal t. Further, the work W immediately moves to the next press contact position after the press contact. The subsequent operations are repeated.

[0094] During this time, when the posture around the axis of the pin t is pressed against the 90 ° different from, the axis chuck 90 fourth cylinder 84 where the chuck 90 has reached the standby position P ₀ of the pressure contact is operated Around (around the axis of the extension axis 77)
, The posture is changed by 90 °, and the body is lowered and pressed against in this state. When the pressure contact is completed, the pressure rises, and the fourth cylinder 84 operates again at the pressure contact standby position P ₀ to operate the chuck 9.
0 rotates 90 °, and the posture returns to the original position. In this state, the posture returns to the origin position C ₀ .

The switching of the chuck bodies 94a and 94b with respect to the terminals t and T for one pole and two poles is
When 0 returns to the origin position C ₀ , the operation is performed by operating the rotary actuator 95 as described above.

The basic units 4 of the press-contact mechanism 200 are described above.
And the configuration and operation of the transport mechanism 100 for feeding the workpiece W to the press-contact position. Next, the method of disposing the FOUPIRE R will be described in detail once again.

(4) Arrangement of FOUPIR R As described above, as shown in FIG. 2, the eight FOUPIRERs are provided at the rear of the opposing rows of the basic unit 4 of the press-contact mechanism 200, four by four. However, the four hoouprils R ₁ , R ₂ , R ₃ , R ₄ corresponding to each row are arranged such that three of them R ₁ , R ₂ , R ₃ are vertically stacked at a position close to the apparatus. And the remaining one R ₄ is disposed behind it.

As shown in FIG. 26, _one of the three groups R ₁ , R ₂ , and R ₃ near the apparatus is a cutting position of the hoop H in the hoop feed unit 40 with _{one of} the groups R ₁ having its reel surface horizontal. At the same height (hereinafter referred to as reference height D ₀ ), and the remaining two groups R ₂ , R ₃
They are arranged symmetrically at the same angle of inclination on the upper side and the lower side of the reel R ₁ in the horizontal arrangement. The rear of Ichiki R ₄ are disposed on the reel R ₁ and same horizontal plane of the horizontal arrangement of the apparatus three groups closer R _1, R _2, R _3. Such a manner of arranging the reels is based on the following reasons.

The eight basic units 4 of the pressure welding mechanism 200
All are arranged on the same base plate 1 and each basic unit
The cutting position of the hoop H in the slot 4 is also the same height.
(Reference height D₀)It is in. Therefore, each basic unit 4
Corresponding reel R₁, R_Two, R _Three, R_FourAlso, Hoop H
In order not to bend in the height direction, all are set to the reference height D₀Go
It is desirable to arrange them horizontally.

However, when the reels R are to be arranged in such a manner, the area occupied by the reels R definitely requires an area of eight units, and such an arrangement is obviously useless.

Therefore, in order to reduce the area occupied by the reels R in the horizontal plane, it is conceivable to stack the reels R in the height direction. For example, all eight reels R are made to have the same reel center. When the reels are stacked, the occupied area of the reel R in plan view can be reduced to one reel.

However, when the reels R are stacked,
The reference height D in the basic unit 4 ₀At the same height as
Other than the reel R, its reference height D₀Hoop H
In order to guide the hoop H in the width direction (the height direction of the terminal t)
It will bend and bend in the middle, and if the deflection is large,
Hoop H does not flow smoothly.

In fact, it is an extreme story to stack all eight reels R with the same reel center as described above. In such a case, the height from the reference height D ₀ in the basic unit 4 is increased. The reel R farthest in the vertical direction is bent rather than bent, and it is impossible to guide the hoop H into the basic unit 4.

Therefore, the reel R which is horizontally arranged at the same height as the reference height D ₀ of the hoop H in the basic unit 4 and the one which is stacked thereon are appropriately mixed, and the reel R when viewed in plan is mixed. The above arrangement is a result of minimizing the occupied area of the hoop H in the horizontal plane in consideration of the occupied area of the hoop H and the degree of bending of the hoop H, which is stacked and inclined.

That is, first, in order to reduce the area occupied by the entire apparatus in the horizontal plane, the reel R is pressed by the pressing mechanism 20.
It needs to be placed right next to 0, but if you do,
At the position immediately adjacent to the pressure contact mechanism 200, the reference height D ₀
When the other reels R are inclined and stacked on the reels R arranged horizontally at the same height as the above, the hoops H of the stacked reels R flow smoothly, and Reel R which can take an inclination angle such that there is no influence of bending in the middle when the cutting position is reached.
Tests have shown that the number of stages in the stack must be at most two.

Therefore, of the four reels R ₁ , R ₂ , R ₃ , R ₄ in the row of each basic unit 4 of the press-contact mechanism 200, the first one R ₁ naturally has the reference height D ₀ . A horizontal arrangement beside the device, two of the remaining three R ₂ , R ₃ are arranged above and below the horizontally arranged reel R ₁ at the same inclination angle as described above, and the fourth base R ₄ at the expense of the reduction in occupied space in a horizontal plane, it was placed horizontally immediately behind the same the reference height D ₀ as one group first R _1.

In this way, there is no problem with the deflection of the hoop H, and the occupied area of the hoop R is also equivalent to four units in plan view, and all eight units have the same height. Is half that of the case of horizontal arrangement. In this way, the size of the apparatus can be reduced depending on the arrangement of the FOUPIRER.

The components of the apparatus of this embodiment have been described individually, and finally, the flow of operation of the entire terminal mounting machine will be described.

(5) Flow of Operation of the Entire Apparatus The operator places the work W on the pallet 13 at the start point S ₀ on the X table 12 and starts when all the operating elements of the apparatus are at the origin position. When the button is pressed, first, the pallet 13 is moved to the end point position T ₀ (X-Y
(The origin position of the table 10). Then, the pressing plate 35 descends and presses the work W.

Subsequently, the XY table 10 is operated while the pressing plate 35 keeps pressing the work W, and the work W
The (pallet 13) goes around all the predetermined press contact positions.

Then, the pallet 13 is stopped at each press-contact position, and the above-mentioned press-contact mechanism 200 operates to press the terminal t against the electric wire w on the work W. When all pressure welding is completed,
The pallet 13 returns to the origin position of the XY table.

When the pallet 13 returns to the origin position,
The pressing plate 35 is lifted, and the pressing of the work W is released.

Subsequently, the pallet 13 returns to the start point position S ₀ on the X table 12, and the worker collects the work W to complete one IP.
