[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic connector assembling machine for automatically assembling a connector by automatically press-fitting a contact pin into an insulator, and more particularly to a contact in this automatic assembling machine. The present invention relates to a contact supply device that automatically supplies pins.

[0002]

2. Description of the Related Art An automatic connector assembling machine for assembling a connector by automatically press-fitting contact pins into an insulator (insulating housing) that is sequentially conveyed has been known. In such an automatic machine, insulators which are objects of work such as assembly are sequentially supplied from the parts feeder in a state of being aligned in the longitudinal direction and the width direction.
On the other hand, the contact pin is formed into a belt shape in which the contact pin is aligned and held by a carrier, and is wound around a reel. The contact belt is pulled out from the reel and cut into a predetermined size, which is press-fitted into the insulator.

By the way, the conventional automatic connector assembling machine is usually an exclusive automatic machine for assembling certain fixed contacts, and the shape, size, number, etc. of the insulators and contact pins carried by this carrying device are predetermined. It was Therefore, the contact belt pulled out from the reel is cut for each size (predetermined size) having a predetermined number of contact pins to be press-fitted into the insulator,
It is supplied to the press-fitting station. There was only one predetermined size, which made it very easy to feed and cut the contact belt.

[0004]

As described above, in the case where the connector automatic assembly machine has only one type of connector, that is, in the case of the dedicated automatic assembly machine, the contact belt has only one cut size. , It is easy to supply and cut, but in the case of a general-purpose automatic assembly machine that is the subject of the present invention, there are multiple types of connectors to be assembled, and the shape and cut dimensions of the contact belt differ for each type. However, there is a problem that the contact supply device becomes complicated and the operation control thereof tends to be difficult. In many cases, the contact pins are press-fitted side by side in two rows in the insulator. In this case, depending on the connector, some contact pins have different lengths, such as angle type connectors. Some have the same length, such as straight type connectors. When the contact pins are press-fitted in two rows, it is necessary to perform the press-fitting with the tips of the contact pins on the side press-fitted to the insulators aligned, but it is possible to assemble both types of connectors as described above. The problem is that it's difficult to do.

Further, in such an automatic assembly machine,
The contact pins are pressed into the insulator while being aligned and held by the carrier.If there is a defect (alignment failure) such as bending or falling, the contact pins are pressed into the insulator as they are. Even if an attempt is made, the misaligned contact pin cannot be properly press-fitted because it is displaced from the insertion hole of the insulator. Therefore, conventionally, before performing this press-fitting,
The presence or absence of misalignment of the contact pins was inspected, and among the contact belts cut into predetermined dimensions, the contact belt including the misaligned contact pins was discarded. However, in this case, if even one misaligned contact pin is included, the entire contact belt including the remaining usable portion will be disposed of, and the effective use efficiency of the contact belt will be reduced accordingly. There's a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a contact supply device for a general-purpose automatic assembly machine which has a relatively simple structure and whose operation control is also simple. The object of the present invention is to make it possible to minimize the number of contact belts to be discarded when there are misaligned contact pins in the contact belts to be disposed.

[0007]

In order to achieve such an object, a contact supply device according to the present invention comprises a belt withdrawing means for sequentially withdrawing a contact belt wound on a reel for each predetermined size, and this belt withdrawing means. The contact cutting means that cuts the contact belt pulled out by a predetermined size, the defect detection means that detects misalignment of the contact pins of the contact belt that is pulled out and conveyed by the belt pulling means, and the operation amount of the belt pulling means. A position detecting means for detecting the conveying position of the contact belt from the operation amount, and a controller for setting the above-mentioned predetermined dimension according to the type of the connector to be assembled and controlling the operation of the belt pulling means and the contact cutting means. And is configured. Where the controller is
Normally, the operation of the belt withdrawing means and the contact cutting means is controlled so as to pull out and cut the contact belt for each predetermined size. On the other hand, when the misalignment detection means detects misalignment, the position of this misaligned contact pin is calculated from the detection signal from the position detection means,
When this misalignment exists within a predetermined size to be cut by the contact cutting means, the amount of withdrawal of the belt withdrawing means is adjusted to cause the contact cutting means to cut the contact belt immediately after the misaligned contact pin. . The contact belt including the misaligned contact pins thus cut is discarded. Next, the controller controls the operation of the belt withdrawing means and the contact cutting means from the position immediately after the defective contact pin to perform the cutting for each predetermined dimension from the next time.

Further, another contact supply device according to the present invention is particularly provided with a contact pin on the insulator.
It is used in an automatic connector assembling machine that assembles connectors by arranging them in a row and automatically press-fitting them. A fixed base for holding one of them, a movable base for holding the other belt withdrawing means and capable of moving up and down with respect to the fixed base, and a contact cutting means for cutting the contact belt drawn out by the belt withdrawing means to a predetermined size. And a controller for controlling the operation of the belt withdrawing means and the contact cutting means by setting a predetermined dimension according to the type of the connector to be assembled, and the controller further includes a controller to the type of the connector to be assembled. Movable base so that the tip positions of the contact pins on both belt means are aligned accordingly To adjust the vertical position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. The contact supply device according to the present invention is used, for example, in a general-purpose automatic assembly machine for assembling the connectors 1 and 5 having the configurations shown in FIGS. 4 and 5.
The connector 1 shown in FIG. 4 is composed of an insulator 2 and a plurality of contacts 11a, 11b press-fitted from the rear end side of the insulator 2 with the tips protruding into the internal space 3d. The contact 11a straightly protrudes rearward while being press-fitted. The contact 11b is bent in a crank shape at a portion projecting to the rear end surface of the insulator 2 and then straightly projecting rearward. Below, the connector 1 of such a structure is called a straight type connector.

Similarly, the connector 5 shown in FIG. 5 is also composed of an insulator 6 and a plurality of contacts 13 and 14 which are press-fitted from the rear end side of the insulator 6 so as to project the tips into the internal space 7d. . All contacts 1
3, 14 are bent downward at a right angle on the rear side (tail side). At this time, the upper contact 14 is longer than the lower contact 13 so that the bent ends are aligned. Below, the connector 5 of such a structure is called an angle type connector.

FIGS. 4 and 5 show two types of connectors 1 and 5 having different basic configurations. However, in the general-purpose automatic assembly machine described below, not only the assembly of these types of different connectors, Even with the same type, it is possible to assemble connectors having different sizes of insulators, different sizes of contacts, and the like. In order to assemble various connectors in this manner, various contrivances have been made in this general-purpose automatic assembly machine. First, an outline of the assembly process by this general-purpose automatic assembly machine is shown in FIG. This will be described with reference to FIG.

In the general-purpose automatic assembly machine, the insulators 2 are supplied one by one from the vibrating parts feeder 20 in a line in a predetermined direction. As shown in FIG. 2, the insulator 2 thus supplied has the first transport path 3
0 to the insulator alignment device 50.
The insulators 2 are supplied side by side in a predetermined direction by the vibrating parts feeder 20, but the vibrating parts feeder 20 cannot align the front and rear and top and bottom (front and back) directions of each insulator 2. Therefore, the external shape of each insulator 2 is read by the image processing device, the direction of each insulator 2 is read from the image data, and the direction of each insulator 2 is aligned by the insulator aligning device 50. After that, the insulators 2 whose directions are aligned in this way are sequentially sent to the transport holding device 80 through the second transport path 70. The step of aligning the insulators 2 supplied from the vibrating parts feeder 20 as described above, that is, the step of reaching the conveyance holding device 80 from the first conveyance path 30 is referred to as a first station ST1.

On the other hand, the contacts are supplied from the reel 100. As shown in FIG. 6, a contact belt 10 having a large number of contact pins 16 held at a predetermined pitch by a carrier 15 having a pilot hole 15a is wound around the reel 100. Therefore, reel 1
00 to contact belt 10 is the contact feeder 1
It is pulled out by 10 and supplied to the contact cutter 130 and the transport pallet 140. The feeding by the contact supply device 110 is stopped in a state where the contact belt 10 is projected onto the transfer pallet 140 by a predetermined size. Next, the portion protruding onto the transfer pallet 140 is held by the pallet 140, and the held portion is separated from the contact belt 10 on the reel 100 side by the contact cutter 130. As a result, the contact belt 10 cut into the predetermined size is held by the transport pallet 140. The process of pulling out the contact belt 10 from the reel 110 and cutting the contact belt 10 to a predetermined size as described above is referred to as a second station ST2.

The transport pallet 140 holding the contact belt 10 cut into a predetermined size as described above is transported on the rectangular transport device 300. This quadrilateral transfer device 300 includes first to fourth transfer rails 310, 320, 33.
0, 340, and these transport rails form a square loop transport path as shown in FIG. The first transfer base 350 is mounted on the first transfer rail 310,
The transfer pallet 140 is placed on the first transfer base 350. As described above, the first transfer base 350 moves from the position adjacent to the contact cutter 130 on the first transfer rail 310 in the direction of arrow A in FIG. 2 to the position adjacent to the temporary contact insertion device 160. Therefore, the transfer pallet 140 is also moved onto the temporary contact insertion device 160 together with the first transfer base 350 while holding the contact belt 10 that has been cut to a certain size.

On the other hand, the insulator 2 sent to the carrying / holding device 80 is gripped by the manipulator arm of the first handling robot 410 arranged in the vicinity of the temporary contact inserting device 160, and the temporary contact inserting device 160 is kept in that state. Transport pallet 14 that has moved to the top
Transported above zero. Next, the image processing device for alignment enters between the contact belt 10 held by the transport pallet 140 and the insulator 2 held by the manipulator arm, and the contact insertion hole of the insulator 2 with respect to the position of the contact pin 16 of the contact belt 10. Read the position of. Then, based on the read image data, the positional deviation of the insertion hole of the insulator 2 with respect to the contact pin 16 is corrected by operating the manipulator arm. Next, the manipulator arm is moved downward while being held by the manipulator arm to press the insulator 2 onto the contact belt 10, and the contact pin 16 is lightly inserted into the contact insertion hole of the insulator 2. The process of temporarily inserting the contact pin 16 into the contact insertion hole in this manner is referred to as a third station ST3.

After the contact pin 16 is temporarily inserted in this way, the insulator 2 using the manipulator arm is inserted.
Is released, and the manipulator arm retracts to a predetermined position. As a result, the insulator 2 is temporarily inserted and attached onto the contact belt 10 held by the transport pallet 140. Next, in this state, the transfer pallet 140 is transferred to the first transfer base 350.
A second transport base which is moved away from the second transport rail 320, is transported in the direction of the arrow B on the second transport rail 320, and is located on the third transport rail 330 so as to face the second transport rail 320. It is conveyed onto 360. The contact press-fitting device 180 is located above the second transfer base 360 at this position. When the transfer pallet 140 is transferred onto the second transfer base 360, the insulator 2 temporarily inserted into the contact belt 10 held thereby is pressed by the contact press-fitting device 18, and the contact pins 16 are inserted into the contacts of the insulator 2. Fully press fit into the hole. The press-fitting process by the contact press-fitting device 18 is referred to as the fourth station ST4.

When this press fitting is completed, the second transfer base 3
60 is a third pallet with the transfer pallet 140 placed thereon.
It is moved in the direction of arrow C on the transport rail 330 to the transport position indicated by the chain line in FIG. 2, that is, to the position indicated by the solid line in FIG. 2 and 3 both show a general-purpose automatic assembly machine according to this embodiment.
Shows the first half of the process, and FIG. 3 shows the second half of the process. However, FIG.
3 and FIG. 3 show a part of the transport device 300 in an overlapping manner.

Next, the second handling robot 420 is operated, and the manipulator arm of the second handling robot 420 grips the insulator 2 on the transfer pallet 140. At this time, the holding of the contact belt 10 by the transfer pallet 140 is released, and the manipulator arm transfers the insulator 2 into which the contact pin 16 is press-fitted onto the carrier cutting device 200. In the carrier cutting device 200, the contact belt 10 in which the contact pin 16 is press-fitted and attached to the insulator 2
The carrier 15 of is separated from the contact pin 16. As a result, the contact pins 16 are independently press-fitted into the contact insertion holes of the insulator 2. The process of separating the carrier 15 by the carrier cutting device 200 is referred to as a fifth station ST5.

When the separation of the carrier 15 is completed, the third handling robot 430 is operated to grip the insulator 2 on the carrier cutting device 200 and convey it to the first bending device 220. In the first bending device 220, the tail portion of one row of the contact pins 16 that are press-fitted into the insulator 2 and project in two rows is bent into a predetermined shape. When this first bending process is completed, the fourth handling robot 440 is operated to grip the insulator 2 on the first bending device 220 and convey it to the second bending device 250. In the second bending apparatus 250, the tail portions of the contact pins 16 forming a row on the side that has not been bent yet are bent into a predetermined shape. Both of these bending devices 2
When the bending process of the tail portion of the contact pin 16 by 20, 250 is completed, the connectors 1, 5 having the configuration shown in FIG. 4 or 5 are completed. The bending process performed by these bending devices 220 and 250 is referred to as sixth and seventh stations ST6 and ST7.

The first to seventh stations ST1 to ST
1 is schematically shown in FIG. 1, and the controller 510 controls the operation control of the devices constituting each station and the operation of the parts feeder 20. This operation control differs depending on the type of the connector to be assembled. Therefore, data on the connector to be assembled is input from the input device 500 to the controller 51 prior to the assembly work.
It is designed to be input to 0.

Since the contact supply device according to the present invention is included in the second station ST2,
The station ST2 will be described below. This second
The station ST2 is shown on an enlarged scale in FIG.
The station ST2 is a contact supply device 110 that pulls out the pair of contact belts 10 from the reel 100.
A transport pallet 140 that holds the tip of the contact belt 10 and a contact cutter 130 that cuts the contact belt 10 at a predetermined dimension.

The contact supply device 110 has a fixed base 111 and a movable base 121.
Can move up and down. The contact belt 1 from the reel 100 is provided on each of the bases 111 and 121.
Correcting rollers 112 and 122 for correcting a 0 warp (a warp caused by being wound on the reel 100), supply detection sensors 113 and 123 for detecting whether or not the contact belt 10 is supplied, and a pitch direction of the cotact pin 16 in the pitch direction. A laser sensor 114 for detecting a defect (alignment defect),
124 and the touch sensor 115 for detecting the tilt of the contact pin 16 (alignment failure in the direction perpendicular to the pitch direction),
125 and drive sprockets 116 and 126 for pulling out the contact belt 10 are arranged along the conveyance direction of the contact belt 10. The guide rollers 117a, 117b and 127 that guide the contact belt 10 so as to be conveyed in this conveying direction.
a and 127b are also disposed on both bases 111 and 121 as shown in the figure.

In the contact belt 10 supplied from the reel 100, for example, as shown in FIGS. 8A and 8B, some contact pins 16 are deformed in the pitch direction as indicated by a1, or It may be chipped as indicated by a2, or may be overturned as indicated by a3.
Therefore, defects in the pitch direction as indicated by a1 and a2 are detected by the laser sensors 114, 124, and defects as indicated by a3 are detected by the touch sensors 115, 125.

The teeth of the drive sprockets 116 and 126 mesh with the pilot holes 15a formed in the carrier 15 of the contact belt 10, so that the drive sprockets 11 can be driven.
The contact belt 10 is pulled out in accordance with the rotation of 6,126. A drive motor (not shown) is attached to each of the sprockets 116 and 126, and an encoder (not shown) that detects the rotation of the sprockets 116 and 126 is attached. Therefore, the transport amount of the contact belt 10 is accurately detected by this encoder. Further, the laser sensors 114, 1
Since the positional relationship (distance) between the 24 and the touch sensors 115, 125 and the drive sprockets 116, 126 is determined, when a defect is detected by these sensors, the position of the defective contact pin is accurately known from the detection value of the encoder. be able to.

The vertical movement control of the movable plate 121 will be described below. The pair of contact belts 10 conveyed on both the plates 111 and 121 correspond to each row of the two rows of contacts inserted into the connector. Figure 4
In the case of the straight type connector 1 shown in (1), since the lengths of contacts in both rows are the same, both plates 111,
121 are positioned so that they are at the same level. However, in the case of the angle type connector 5 shown in FIG. 5, the contacts 14 forming the upper row are longer than the contacts 13 forming the lower row. Correspondingly, contact belts having different lengths are used, but at this time, if both plates 111 and 121 are at the same level, there is a problem that the upper end positions of the contact pins of the contact belt are different. Therefore, in this case, as shown in FIG. 9, the vertical position of the movable plate 121 is adjusted, and for example, the contact pin 1 of the contact belt 10 having a short length conveyed on the fixed plate 111.
The upper and lower positions of the upper end 16a of 6 are made equal to the upper and lower positions of the upper end 16a 'of the contact pin 16' of the contact belt 10 'having a long length conveyed on the movable plate 121.

As described above, the contact supply device 1
The pair of contact belts 10 pulled out from the reel 100 and conveyed by 10 are sent to the conveyance pallet 140 through the contact cutter 130 shown in detail in FIG. The contact cutter 130 is composed of a pair of left and right cutting devices, and each cutting device has a fixed plate 111 and a movable plate 12, respectively.
It is mounted on 1.

The two cutting devices respectively include a cutting reinder 131, a movable block 132 moved by the cutting cylinder 131, and a movable block 1.
The pressing plate 134 is movably guided by the guide pin 133a with respect to 32 and is connected via a compression spring 133b between the pressing plate 134 and a cutting member 136 coupled to the side surface of the movable block 132. A pair of separator plates 13 facing the pressing plate 134
5 are mounted on the fixed plate 111 and the movable plate 121. When the contact belt 10 is conveyed, the movable block 132 is pulled outward by the cutting cylinder 131, and the pressing plate 134 and the separator plate 135 face each other with a predetermined gap.

As shown in FIG. 7, the transport pallet 140 has an arrow J on the rail 351 on the first transport base 350.
When the contact belt 10 supplied from the contact supply device 110 is received, the contact belt 10 is moved to a position close to the contact cutter 130 as illustrated. This transport pallet 140
Is a pair of left and right clamp cylinders 141 mounted on the base plate 150, as shown in FIGS. 10 and 11A (cross-sectional view taken along the arrow ZZ in FIG. 10).
And a pair of left and right clamp blocks 142 locked to the rod 141a of the clamp cylinder 141, and a pair of left and right compression springs 144 that bias the clamp block 142 toward the center. Further, on the holding block 151 attached to the base plate 150, the fixing member 1
A separator plate 153 is fixedly held by 52 and protrudes between the clamp portions 143 of the left and right clamp blocks 143.

A pair of rail blocks 155 are mounted in the holding block 151 so that the transfer pallet 140 can be used as the second and fourth transfer rails 320 and 340.
When the rails are transported up, the cylindrical rails enter the guide holes 155a of the rail blocks 155 and are transported along the rails. In addition, the transport pallet 14
Reference numeral 0 also has a positioning cylinder 157, and the positioning cylinder 157 can adjust the positions of all members on the base plate 150 in the left-right direction.

When the contact belt 10 is supplied from the contact supply device 110, the clamp block 1
42 is pulled out by the clamp cylinder 141, and the clamp portion 143 is separated from the separator plate 153. Then, the pair of contact belts 10 supplied from the contact supply device 110 is fed between the clamp parts 143 on both sides of the separator plate 53 through the contact cutter 130. When the contact belt 10 is fed by a predetermined size, driving of the drive sprockets 116 and 126 is stopped, and then the rod 141a of the clamp cylinder 141 is pushed out.
As a result, the clamp block 142 is compressed by the compression spring 144.
Is urged toward the center by the urging force of the clamp portion 143.
Sandwiches the contact belt 10 with the separator plate 153.

As shown in FIG. 11B, the clamp portion 143 has a comb-shaped first clamp surface 143a on the upper side,
It has a flat second clamp surface 143b on the lower side,
The root portion of the contact pin 16 of the contact belt 10 is gripped by the first clamp surface 143a, and the carrier 15 is gripped by the second clamp surface 143b. Therefore, the upper portion of the contact pin 16 is in a state of protruding upward while being clamped by the clamp portion 143.

When the contact belt 10 is sandwiched by the transport pallet 140 in this way, the cutting cylinder 131 of the contact cutter 130 is then actuated to push the movable block 132 to the center. When the movable block 132 is pushed out, the pressing plate 134 is pushed out via the compression spring 133b.
Due to the spring force of 3b, the pressing plate 134 holds the subsequent portion of the contact belt 10 between itself and the separator plate 135. Almost at the same time as this clamping, the movable block 13
The blade edge 13 of the cutting member 136 by the extrusion of 2
6a projects beyond the front end surface of the pressing plate 134, cuts the contact belt 10 at this portion, and separates the contact belt 10 held by the transport pallet 140 from the subsequent contact belt 10.

The separation of the contact belt 10 is usually performed for each predetermined size of the contact belt 10, but the contact belt 1 is separated by the laser sensors 114 and 124 and the touch sensors 115 and 125.
If a defect is detected in the contact pin 16 of 0,
A cut for removing this portion is also performed. For example, in FIG.
As shown in (C), a
As shown in 2, when a defect of one contact pin 16 is detected, the accurate position can be grasped by the encoders mounted on the drive sprockets 116 and 126. You can cut each L1. Then, when the contact belt 10 is cut to a position (p2) in which the defective contact pin is included in the predetermined dimension L1, the contact belt 10 is cut at a position (p3) on the rear side of the defective contact pin, and the cut portion is discarded. To reject. After this, cutting is newly started from this position p3 for each predetermined dimension L1. By doing so, it is possible to minimize the portion that is discarded when a defective contact pin is detected. In addition, when disposing of the cut portion, the transfer pallet 140 is temporarily retracted, and a waste component is received up to the side of the contact cutter 130 (not shown).
To move.

When the separation of the contact belt 10 is completed in this way, the transfer pallet 140 is moved to the rail 35.
It is moved by a predetermined amount in the direction away from the contact cutter 130 on the top 1. By this movement, the transport pallet 140
There is no risk of interference between the contact temporary contact insertion device 160 and the contact cutter 130, and the first transfer base 350 is placed on the first transfer rail 310 in the direction of arrow A (see FIG. 2) of the temporary contact insertion device 160 while the transfer pallet 140 is placed. It is transported to the position.

As described above, in the contact supply device according to the present invention, the controller is usually
The operation of the belt withdrawing means and the contact cutting means is controlled so as to pull out and cut the contact belt for each predetermined size, and when the defect detecting means detects misalignment, this is detected from the detection signal from the position detecting means. The position of the misaligned contact pin is calculated, and when this misalignment exists within the predetermined dimension to be cut by the contact cutting means, the pull-out amount of the belt withdrawing means is adjusted to make contact at the position immediately after the misaligned contact pin. The contact belt is cut by the cutting means, and then the controller controls the operation of the belt withdrawing means and the contact cutting means so as to carry out the cutting for each predetermined dimension from the position immediately after the defective contact pin. In this case, the contact belt containing the cut misaligned contact pins is discarded, but since the contact belt is cut immediately after the misaligned contact pin, the scraped contact belt is kept to the minimum necessary. Can be suppressed.
