Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention cuts a wire supplied from a reel into a predetermined length, and inserts the cut end of the wire into a predetermined insertion hole of a printed circuit board. This is related to an automatic jumper wire insertion machine.

[Prior art]

Move the printed circuit board horizontally, front and back, left and right, that is, X-Y.
An automatic component insertion machine is known that automatically inserts the terminals of electrical components such as transistors, resistors, or capacitors from above the printed circuit board placed on a table that is transported in the direction. The majority of printed circuit boards used in electrical equipment are fitted with electrical components using this automatic insertion machine, making a major contribution to supplying a large quantity of stable products free of human errors. I am accomplishing it.

As mentioned above, this type of conventional automatic component insertion machine inserts multiple terminals established on the component body, such as transistors, resistors, or capacitors, into the insertion holes of the printed material. Therefore, by tapping a predetermined part of the component body, it is possible to locate the terminals of the component by oneself, and therefore it is relatively easy to insert the terminals of the component into the stored position on the printed circuit board. It is easily possible.

However, it is impossible to insert the end of a flexible wire different from the electrical components mentioned above into the insertion hole of the printed circuit board, and insertion of the flexible wire must be done manually. is the current situation.

In recent years, work efficiency in producing printed circuit boards has become more and more important, and as shown in Japanese Patent Publication No. 43-24031, for example, a perforation-like dividing line is provided in advance in the center of a printed circuit board, and A flexible wire, that is, a jumper wire, is used to connect the two through the split line, and after automatic soldering, the two base plates are connected along the perforation-like split line.
A method of dividing or further dividing is also adopted.

In order to improve the efficiency of such work, jumper wires must be inserted manually as mentioned above, which causes problems such as decreased work efficiency and variation, and increased repair man-hours due to human error. [To reduce connection mistakes] Connect both ends of the Ume jumper wire to the multi-connector, and connect the connector to the corresponding connector or wrapping terminal placed on the printed circuit board via the -ζ jumper. Currently, processes such as connecting wires are not required in advance, which is a major hindrance to reducing manufacturing costs.

[Object of the present invention]

This invention is a jumper wire that can sequentially draw out jumper wire material wound on a reel, cut it to a predetermined length, peel off the coating on the end, and then continuously insert the end into a predetermined insertion hole of a printed circuit board. The purpose of the present invention is to provide an automatic insertion machine that enables continuous automatic insertion of jumper wires, improves work efficiency, and eliminates the occurrence of erroneous connections.

[Configuration of the present invention]

Before explaining the specific configuration of the automatic insertion machine of the present invention, an outline of the automatic insertion machine of the present invention mainly focused on wire processing will be explained first.

Figure A shows the process of gripping the end of the wire rod 2 wound on the reel 1 with the chuck 9 and pulling out the wire rod 2. The wire pulled out by the chuck 9 is let out for a predetermined length by a movable roller 20 moving between a pair of fixed rollers 19, 19, as shown in Figure B, and the wire length is determined. In this state, as shown in Figure 0, the coating on both ends of the wire +A2 is peeled off by a pair of cutters 11, 11, and then, as shown in Figure D, both ends of the wire are gripped by a pair of insertion heads 13, 13,
The core wires from which the coating has been peeled off are each bent downward and inserted into a predetermined insertion hole of the printed circuit board 4 by a pair of insertion heads 13, 13 as shown in FIG.

The Nyanbar wire whose end is inserted as shown in Fig. E is cut horizontally from below by a pair of cutters 21 and 21 as shown in Fig. F, and the cut is cut horizontally into the printed circuit board 4. He was clinched against the opponent.

The following is an overview of the wire processing for jumper wires.

Next, the general structure and operation of the automatic insertion machine of the present invention as a whole will be explained, and then the detailed structure and operation of each main part will be explained in order.

[Overall schematic structure and operation of automatic jumper wire insertion machine] Figures 2 to 6 show an overall overview of an embodiment of the present invention. In FIGS. 2 to 6, 1 is a wire supply reel, and 2 is a wire supplied from a cigarette burner l. Reference numeral 3 denotes a table on which a printed circuit board 4 into which both ends of the processed wire are inserted is placed and fixed, and this table is controlled by numerical control so that it can be transported horizontally in the front, back, left, and right directions, that is, in the x-y directions. Supported.

Each of the above-mentioned cams transfers the corresponding transmission rotor l-L to a lever J that transports it in its axial direction, and a drawer chuck r that transfers the wire rod 2 fed out from the reel 1 to the machine for seven strokes.
g+<9, a wire length determining unit section 10 which determines the wire length of the wire rod 2 that has been sewn by the drawer chuck section 9, cants the wire rod determined by the wire length determining unit section 10, and peels off the coating at both ends thereof. A hook part 11, a delivery feed chuck part 13 that transfers the canted wire rod to the insertion head part 12, and a delivery feed chuck part 1;
It is used as a timing operation source for the insertion head section 12, etc., which inserts the wire passed from the wire rod 3 into the insertion hole of the printed circuit board 4.

Hereinafter, the details of each part shown in r6/Nos. 9 to 13 will be described in separate sections later.

Next, an outline of the operation will be explained based on the following configuration.

The wire rod 2 supplied from the reel 1 passes through a guide nozzle 14 and a driving roller 15 as shown in FIG. Sent to 18th.

Note that S, which is not shown in Figure 5, is Mitsushi Suinona, which is
From Le 1, the effect of pulling out the line + A2 with some margin-]. -4- That is, when the wire rod 2 is pulled out in the direction of the kite pipe 16, the wire rod 2 loses its slack and is pulled in two directions as shown in FIG. As a result, a motor (not shown) that rotationally drives the drive roller 15 rotates, and the wire 2 is pulled out from the reel 1 by the drive roller 15 driven by this motor. The drive roller 15 is rotated by the motor until the wire rod 2 or the wire rod detection photoelectric switch S+:la is reached.
By this operation, the wire rod 2 is always drawn out in a U-shape as shown in FIG. 5, and acts so that no load is applied to the wire rod 2.

The wire rod 2 drawn out in this manner is corrected in its posture by the five rollers 17 as described above, and is supplied to the nozzle 18. Here, the drawer chuck section 9 pulls out the wire 2 from the nozzle 18. That is, the pull-out chuck section 9 is moved from the position shown in FIG. 6 to the right, ie, to the nozzle 18 portion, with the chuck open, and chucks the lines 4 and 12 protruding from the tip of the nozzle 18. In the chunked state, move to the left in the figure and return to the state shown in FIG.

The more specific structure and operation of the drawer chuck part 9 will be described later, but when the chuck part moves from left to right in FIG.
It passes over the two cutter parts 11 existing on the opening movement path, and after chucking the wire, passes between the open cutter parts 11 when moving to the left from "A" in the figure,
It acts to draw in the wire rod 2.

In this state, the wire length of the wire rod 2 is determined by the wire length determination unit section 10. The wire length determining unit 10 basically consists of 2
It is composed of two fixed rollers 19, 19 and a moving roller 20 that moves between them.The movement of the moving roller 20 draws the wire into a U shape, and the length of the wire 2 is determined by the amount of movement of the moving roller 20. Ru. The wire rod whose wire length has been determined by the wire length determining unit 1O is chucked at both ends by the delivery and feeding chuck section 13 shown in FIG. The details of this mechanism will be described later, but the chuck is located inside the two cutter parts 11 and the fixed roller 19,
Located outside of 19. After both ends of the wire rod 2 are chucked, the pull-out chuck 9 is opened, and then the blades of the cutter part 11 are closed and moved in the left and right directions. By this operation, the coating on both ends of the wire 4A2 can be peeled off.

The cut and stripped wire rod 2, ie, the jumper wire, remains chucked in the delivery and feeding chuck section 13, and the chuck rotates and is delivered to the pair of insertion head sections 12. This insertion head section 12 has a function of bending the core wire part from which the coating has been peeled downward while holding both ends of the jumper wire 2, and moves downward and is placed on the X-Y table 3. Insert the core wire portions at both ends of the jumper wire 2 into the predetermined insertion holes of the printed circuit board 4.

Note that a cant-and-clinch mechanism is provided as necessary directly below the insertion head section 12, that is, on the lower surface side of the print 1 to the substrate 4 placed on the X-Y table 3, and the excess end of the inserted jumper wire 2 is and simultaneously clinch the cut ends against the handle.

Furthermore, the moving roller 20 is moved up and down by the operation of the cylinder 39 via the lever 43. The fixed roller 19 moves on a slider base 46 via a roller bracket 44 and a roller slider 45 by driving a cylinder 47.

Here, when the cylinder 39 is driven to retract, the moving roller 2
0 is lifted upward as shown by the chain line. Further, the fixed roller 19 is moved to the right in FIG. 10 by being driven by the cylinder 47.

This state is shown in FIG. 12A. Next, the wire drawing chuck 9 passes through the center, and the wire guide 2 is drawn in. Then, the cylinders 39 and 47 are driven into a protruding state, and the wire 2 is sandwiched between the moving loaf 20 and the fixed roller 19. This state is shown in FIG. 12B.

At this point, the pulse motor 34 rotates, and the movable roller 20 slides to the left in FIG. That is, Figure 12C
As shown in FIG. 2, the wire kA2 is drawn into a beam shape, and the amount of drawing is determined by the number of pulses given to the pulse motor 34, and the length of the jumper wire is determined here.

After the line length is determined and the pulse motor 34 stops driving,
The pulse motor 34 rotates in the opposite direction and returns to its original state.

At this time, after returning a certain distance, the cylinder 39 performs a retracting operation, and the moving roller 20 moves upward as shown by the chain line in FIG. 10, completing one stroke of the line length determining unit.

After the wire length is determined in this way, the cutter part 11 located outside the pair of fixed rollers 19 cuts the wire rod 2 as described above.

48 is a drive lot for driving this mechanism;
9 is the 9th rank taken at the tip of the drive rod 48. A pinion 50 is engaged with the nine rack 49,
It is rotated by moving the nine-way sole 49 in the longitudinal direction.

The shaft 51 of the pinion 50 is connected to a cylinder 52, and a piston 53 is housed in the cylinder 52. The movement of the screws 1 and 53 within the cylinder 52 causes the pair of clampers 54 and 55 to move against the shaft 56 and the piston 53, respectively. Opening and closing operations are performed using 57 as a fulcrum. This clamper functions as a chuck.

A spring receiver 58 is attached to the nine rack 49, and a coil spring 60 is stored in a compressed state between it and the rank presser 59.

rotates counterclockwise about the shafts 56, 57 as fulcrums as shown in FIG.

At this time, the slider 61 is pressed against the stopper 63 by the pressure of the spring 60.

Next, when the drive rod 48 is pushed out, the cylinder 52 rotates to the left due to the action of the round rack 49 and pinion 50.
The state shown in FIG. 14 is reached. During the transition from the state shown in FIG. 15 to that shown in FIG. 14, the spring 60 is compressed and presses the rank presser 59 to hold the slider 61 at the upper right end position.

In the state shown in FIG. 14, the cylinder 52 hits the top surface of the slider 62, making it impossible for the pinion 50 to rotate, and the nine rack 49 and pinion 50 are in a rigid state. If the drive rod 48 is further pushed out in this state,
As shown in FIG. 16, the slider 61 is connected to the slide base 6.
The movement is to slide down on the top of 2 towards the lower left.

The position of the slider 62 shown in FIG. 16 is the position for transferring the wire rod 2, that is, the jumper wire, and by releasing the air from the cylinder 52 at this point Z, the clamper 54.55
becomes open. Then, as shown in FIG. 14 from FIG. 16, the drive rod 48 is pulled up again, and when the slider 3 hits the slider 63, the pinion 5o rotates again and acts to move the clampers 54 and 55 upward. Get ready to receive the next jumper wire.

In the above configuration, as shown in FIG. 18A, the push rod 6
The wire rod 2 is held by the chuck 5 and the chuck 64. In this state, the slide bar 66 is
is coming down. Since the bending rod 74 is attached to the slide bar 66, the bending rod 74 and the slide bar f
i fi]・falls at the same time as falling. Here, the push rod 65 supported by the lower bending rod 74 is pushed down by the spring 72. Therefore, the wire rod 2 is the push rod 6
4, it is fixed without loosening. The pressure of the push rod 64 can be set arbitrarily by the spring constant of the spring 72.

When the slide bar 66 further rises F, the bending rod 74 bends the core wire 2' portion of the wire 2 downward, and the upper part of the slide bar 66 is bent at the position where the lower end of the chunk 64 and the lower end of the bending rod 74 coincide. It hits the head slider 76. At this time as well, the pressure of the push rod 65 becomes the pressure of the spring 72.

From this point on, the slide bar ti6 also pushes down the hex slider 76 and descends to the insertion surface in the state shown in FIG. 17C.

FIG. 18A shows a state in which the core wire 2' of the printed circuit board 4-1 line 2 has arrived due to the above-described downward action.

In this state, the wire rod 2 is fixed by the chuck 64 and the push rod 65. Next, when the insertion rod 67 is pushed downward, the cam 68, which moves in the same direction as the insertion rod 67, pushes up the hair ring 70. , fulcrum pin 69
Use this as a fulcrum to open the chuck to the left. (Figure 18B)
When the insertion rod 67 further descends, the push rod stopper 71 is pushed down as shown in FIG. The pressure at this time is also determined by the spring constant of the spring 72, and the end of the wire 2 is stably inserted into the printed circuit board 4.

When the slide no. 1-66 rises in the state shown in FIG. 18C, the chuck 64 rises to a certain position while remaining open as shown in FIG. 18C.

The operation during lifting is completely opposite to the above-mentioned operation for chucking the wire. Further, the closing operation of the chuck 64 is also the opposite of the opening operation.

The head portion, which is not shown or shown in FIGS. 17 and 18, is supported by a hair ring on one side thereof, and is configured so that it can be rotated arbitrarily in the circumferential direction, and the direction of the wire rod can be arbitrarily selected. has been done.
