Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic component mounting device.

More specifically, the present invention relates to an apparatus for cutting and bending lead wires of electronic components inserted into mounting holes of a printed circuit board and protruding toward the back side thereof into predetermined lengths.

(Prior Art) Conventionally, there are various types of electronic component mounting devices that automatically cut and bend the lead wires of electronic components inserted into the mounting holes of printed circuit boards and protruding to the back side to a predetermined length. A representative example thereof is disclosed in Japanese Patent Application Laid-open No. 184793/1983.

Specifically, the center carrier is disposed below the printed circuit board so that it can move in two mutually orthogonal directions in a plane parallel to the printed circuit board set on the work table, and the piston rod is moved toward the printed circuit board. A hydraulic actuator mounted on the carrier so as to be able to project a predetermined stroke and rotate at a predetermined angle with respect to the center line of the piston rod, a head table fixed to the upper end of the piston rod, and a fixed knife and a movable knife. A pair of cutter devices are mounted on the head table so that the pairs face each other, and a pair of lead wires of the electronic component inserted into the mounting hole of the board and protruding to the back side thereof are provided. An electronic component mounting device is disclosed that is configured to be received into a cutting hole provided in a fixed knife and to be able to cut and bend the fixed knife to a predetermined length by acting on the fixed knife with a movable knife.

(Problems to be Solved by the Invention) However, in this known mounting device, both cutter devices are mounted so that the pair of fixed knife and movable knife can move in directions facing each other. Moreover, the device configuration was complicated and its operation and operation was troublesome.

That is, in order to receive the lead wire into the cutting hole provided in each stationary knife, both cutter devices must be positioned so that the cutting hole is located on the extension of the lead wire, but this method is not suitable for the known mounting method. In the device, since both cutter devices are mounted so as to be movable as described above, the movement of the center carrier is controlled so that the center of the piston rod of the fluid pressure actuator is located at the midpoint between the pair of lead wires. While performing this, the rotation of the fluid pressure actuator is controlled to position both cutter devices in the direction of cutting and bending, and the movement of both cutter devices is controlled to adjust the pitch between the cutting holes to the pitch between the pair of lead wires and position them. Therefore, the configuration of the device is complicated and the operation thereof is also troublesome.

In addition, in order to collect the lead wires cut by the pair of cutter devices without scattering them onto the head table, etc., the lead wires are inserted into the cutter bracket to which the fixed knives are fixed, and are connected to the cutting holes of the fixed knives. A hole is bored and a discharge pipe is connected to the insertion hole, and while both cutter devices are in operation, air in the discharge pipe is sucked and the cut lead wire is discharged to another appropriate location.

However, because the pipe has to be small in diameter due to the structure of the device and must be bent appropriately, the pipe is easily clogged and it is difficult to always properly discharge the lead wire. .

Therefore, we focused on this problem, and as a result of intensive study from various angles in order to improve it, we decided to fix one of the pair of cutter devices to the head table and mount the other cutter device so that it can be moved. For example, we have found that the device configuration can be simplified and operation can be made easier, and we have proposed this type of electronic component mounting device in another application, but in this case as well, we have not solved the problem of discharging the cut lead wires. The problem had not yet been fully resolved.

Therefore, as a result of intensive study from various directions to further improve this point, we drilled a through hole in the piston rod of the fluid pressure actuator that moves the head table up and down, and used this through hole to discharge the cut lead wire. They discovered that if the lead wires are provided in a manner that allows the lead wires to be properly discharged at all times.

A fixed cutter device having a fixed cutter device fixed on the head table, and a movable cutter device having a pair of a fixed knife and a movable knife and movably mounted on the head table are provided. A pair of lead wires of the electronic component inserted into the mounting holes and protruding to the back side thereof are received into the cutting holes provided in each fixed knife, and the lead wires are removed by causing the movable knife to act on the fixed knife. An electronic component mounting device configured to be able to cut and bend the lead wire to a predetermined length is equipped with a lead wire discharge device that collects cut lead wires and sends them to the upper end of the through hole drilled in the piston rod.

Note that, as shown enlarged in FIG. 4, the fixed cutter 70 has a cutting hole 74 formed therethrough at its distal end and located on the centerline C-C of the piston rod 34. , and as shown in FIG. 5, which is a view taken in the direction of arrow V in FIG. The cutter rod 68 is inserted into the locking recess 76 provided in the movable cutter 69.

Then, by operating the movable cutter 69, it can be cut to a predetermined length and bent inward.

That is, the center carrier 1 is moved by the carrier movement control device 5 and positioned so that the cutting hole 74 of the cutter device 4a is located on the extension of the lead wire 73 of the electronic component 72.

Next, the piston rod 34 of the fluid pressure actuator 2 is projected upward toward the printed circuit board 20, and the head table 3 is accordingly raised to cut the lead wire 73 of the electronic component 72 into the cutting hole 74 of the cutter device 4a. is accepted.

In addition, when the lead wire 73 is received into the cutting hole 74 in this manner, the tip of the fixed cutter 70 is located at a position below the back surface of the printed circuit board 20 suitable for cutting and bending. , the piston rod 66 of the fluid pressure actuator 65 is protruded, and accordingly the movable cutter 69 slides on the fixed cutter 70 toward the printed circuit board 20, cuts the lead wire 73, and then cuts the lead wire 73 inward. It can be folded.

In this way, in this electronic component mounting device,
Since one cutter device 4a is fixed on the head table 3, the cutting hole 74 of the fixed cutter 70 can be directly positioned with respect to the lead wire 73 of the electronic component 72 by controlling the movement of the center carrier 1. Therefore, positioning can be performed easily and with high precision.

On the other hand, the cutter device 4b includes a pair of cutter stands 81a and 81b fixed to the head table 3 by bolts 80, as shown in FIG. 1 and FIG. 6, which is a right side view of this figure.

Therefore, according to this cutter device 4b, the first
As shown in FIG. 7, which is a plan view of the figure, when this cutter device 4b is located on the same center line (X1-X2 line) as one cutter device 4a, the cutter device 4a, the lead wire 73 of the electronic component 72 can be cut to a predetermined length and bent inward.

In FIG. 8, the electronic component 72 is shown bent inwardly by the cutter devices 4a and 4b in directions facing each other and attached thereto.

In this case, the pitch between the cutting holes 74 of one cutter device 4a and the cutting holes 74 of the other cutter device 4b is adjusted to be the same as the pitch between the pair of lead wires 73 of the electronic component 72, so that each hole 74 The lead wire 73 is received inside, and this pitch adjustment can be performed by moving the other cutter device 4b using the cutter base movement control device 100.

This cutter base movement control device 100, as shown in FIGS. 6 and 7 and FIG. 9, which is a view taken from the W arrow in FIG. A stepping motor 103 is fixed to 102 by bolts (not shown), one end of which is connected to the output shaft of this motor 103 via a shaft coupling 104, and a nut 105 attached to the cutter base 83; It consists of a screw shaft 107 whose other end is supported by a bearing 106 mounted on a bracket 102.

Note that the nut 105 is fixed by a flange 109 that is fixed to the nut support portion of the cutter base 83 with a bolt 108.

The cutter base 83 can be moved in the X1-X2 direction together with the cutter device 4a,
The pitch between the cutting holes 74 of the cutter base 83 can be adjusted to a predetermined value. In this case, the moving distance of the cutter base 83 is controlled by the stepping motor 103.
This is done by counting the pulses emitted by the drive. In FIG. 7, it is shown moved to the maximum in the X2 direction, and by driving the stepping motor 103 in reverse rotation, it can be moved in the X1 direction.

In addition, in this way, the cutter device 4b is
An overrun prevention device is provided to prevent troubles such as the cutter device running out of control and colliding with the fixed cutter device 4a when moving in the direction. That is, the detection pin 120 shown in FIG. 7 is inserted into the hole 121 shown in FIG. 6 and is fixed to the cutter base 83, and is also fixed to the cutter stand 61 of the cutter device 4a. A proximity switch is fixed to the holder 122. Although this proximity switch is not shown, it is fixed using the hole 123 of the holder 122.

Therefore, when the movable cutter device 4b approaches the fixed cutter device 4a more than a predetermined distance, the pin 120 is detected by the switch,
Then, based on this detection signal, the driving of the stepping motor 103 is stopped.

Next, in the case where the pair of lead wires 73 of the electronic component 72 arranged in the Y1-Y2 direction perpendicular to the X1-X2 direction in the same plane are cut and bent inward, FIGS. Both cutter devices 4a and 4b are positioned in the Y1-Y2 direction by the table rotation control device 130 shown in FIG. 10, which is an enlarged view of FIG.
This table rotation control device 130 includes a bracket 132 fixed to the center carrier 1 by bolts 131, a stopper 133 screwed to the bracket 132, and an air cylinder type fixed to the bracket 132 by bolts (not shown). a hydraulic actuator 134;

Note that the flange 135 is fixed to the housing 31 with bolts 143 as shown in FIG.

Therefore, by moving the piston rod 137 of the fluid pressure actuator 134 in and out, the housing 31 can be rotated, and the fluid pressure actuator 2 fixed to the housing 31 can also be rotated with respect to the center line of the piston rod 34. Therefore, the head table 3 can be rotated to position both cutter devices 4a, 4b in the X1-X2 direction or the Y1-Y2 direction.

At this time, when the piston rod 137 of the fluid pressure actuator 134 is protruded, the attachment 136 and the flange 135 move to the tenth position.
The piston rod 137 is rotated to the left in the figure, and the piston rod 137 is projected until it abuts against the stopper 133. Further, when the piston rod 137 of the fluid pressure actuator 134 is depressed, the attachment 136 is rotated to the right together with the flange 135, and the piston rod 137 is depressed until it abuts against the stopper 141.

In this manner, the attachment 136 is attached to the stopper 1, as shown in FIG.
33, the cutting holes 74 of both cutter devices 4a, 4b are located in the X1-X2 direction, and when in contact with the stopper 141, they are located in the Y1-Y2 direction.

Although not described in detail, the Y1
The lead wire 73 arranged in the -Y2 direction can also be cut and bent inward.

Further, according to this attachment device, it is also possible to attach it by bending it outward, as an example of which is shown in FIG.

That is, as shown in FIG. 12, after moving the movable cutter device 4b in the Y2 direction with respect to the fixed cutter device 4a,
The cutting hole 74 of both cutter devices 4a, 4b can be positioned in the Y1-Y2 direction.

In this case, the piston rod 91 of the fluid pressure actuator 90 shown in FIGS. 6 and 7 is depressed and the cutter bracket 84 is removed.
is moved in the Y2 direction, and the cutter base 83 is moved in the X1 direction by driving the stepping motor 103. And in this way Y1-
Both cutter devices 4a, 4b located in the Y2 direction
The pitch P between the cutting holes 74 is adjusted to be the same as the pitch between the pair of lead wires 73 of the electronic component 72, and the movable cutter 69 of the cutter device 4a is adjusted to be the same as the pitch between the pair of lead wires 73 of the electronic component 72. The movable cutter 69 of this cutter device 4b is projected in the X1 direction.

In FIG. 11, Y1-
Although the electronic component 72 is shown in which a pair of lead wires 73 arranged in the Y2 direction are bent in a direction away from each other (outward), the pair of lead wires 73 arranged in the X1-X2 direction is shown. can also be folded in the same way.

That is, in this case, both cutter devices 4a,
The cutting hole 74 of 4b is located in the Y1-Y2 direction,
This can be done by moving the cutter bracket 84 in the X1 direction under the control of the fluid pressure actuator 90 and moving the cutter base 83 in the Y1 direction under the control of the stepping motor 103.

In this way, according to this mounting device, X1-X2
A pair of lead wires 73 arranged in the Y1-Y2 direction can be cut to a predetermined length and bent in directions facing each other or in directions away from each other.

The cutter device 4b, which is moved under the control of the fluid pressure actuator 90, is brought into contact with the stopper 95 and positioned on the same center line as the stationary cutter device 4a when bending inward, and is positioned on the same center line as the cutter device 4a on the fixed side. In order to position the movement in the Y2 direction or the X1 direction when bending, a detection piece (not shown) that is fixed to the connecting fitting 93 and moved together with it is fixed to the cutter base 83 (not shown). This is done by controlling the protrusion stroke of the fluid pressure actuator 90 by detecting it with a sensor.

Further, the lead wires cut by both cutter devices 4a, 4b are cut by a pair of screen devices 150a, 150b and a first cutter device shown in FIG.
The lead wires are collected by a lead wire discharging device 153, which is shown in the figure, and are composed of a shooter 151, skirts 152a, 152b, etc., and are fed into a through hole 33 formed in a piston rod 34 and discharged.

Specifically, as shown in FIG. 13, which is a front view of this lead wire discharging device 153, and FIG. 14, which is a plan view of this figure, both screen devices 150a and 150b are used for discharging glass sheets or the like. A screen 154 made of a flexible sheet material for preventing static electricity is installed between the fixed cutter device 4a and the movable cutter device 4b.

One end of the screen 154 is fixed to the cutter bracket 84 of the movable cutter device 4b with a machine screw 156. The other end is supported by a take-up and unwind mechanism 155 whose detailed structure is shown in FIG. 15.

This take-up and unwind mechanism 155 fixes the case 158 to the cutter stand 61 of the stationary cutter device 4a with bolts 159, and
A shaft 162 is rotatably supported by a first cap 160 and a housing 161 screwed to the shaft 162,
Then, firmly nip one end of the screen 154 wound around this shaft 162 with the presser plate 163, and attach the presser plate 163 to the shaft 162 with the machine screw 164.
Furthermore, one end of the spiral spring 165 inserted into the housing 161 is inserted into a slit provided at the lower end of the shaft 162 and locked, and the other end is inserted into a slit provided in the case 158. It is inserted and locked.

Note that 166 is a second cap screwed onto the housing 161.

Since the pair of winding and unwinding mechanisms 155 are installed in this manner, the shaft 162 rotates as the movable cutter device 4b moves, and the screen 154 is automatically wound up or unwound. This allows the screen 154 to be kept in tension at all times. For this reason, both cutter devices 4a and 4b
The cut lead wires can be prevented from scattering, and the collected lead wires can be stored in the shutter 151 disposed below.

The shooter 151 is attached to the head table 3 by bolts 167 shown in FIG. 6 so as not to interfere with the movement of the movable cutter device 4b.

Further, the printed circuit board 20 is set at a predetermined position on the work table 19 by an operator, and in order to attach the electronic component 72 to the circuit board 20, the center carrier 1 is moved to a predetermined position by the carrier movement control device 5. At this time, the head table 3 has been lowered, and when the center carrier 1 is brought to a predetermined position, the fluid pressure actuator 2 is operated and the head table 3 is raised.

Furthermore, while the center carrier 1 is being moved, the rotation of the head table 3 and the movement of the cutter device 4b are controlled.

Then, with the cutting holes 74 of both cutter devices 4a and 4b positioned relative to the pair of lead wires 73 of the electronic component 72, the head table 3
When the electronic component 72 is raised, light is projected from the tip of the tube 172 shown in FIG. into the indicated mounting hole 78.

Next, when the operation pedal 173 is pressed with a foot, the movable cutters 69 of the cutter devices 4a and 4b slide on the fixed cutter 70 toward the substrate 20, cutting and bending the lead wire 73.

After cutting and bending in this manner, the head table 3 is lowered and the center carrier 1 is moved to the next position.

Thereafter, the electronic components 72 can be attached to the printed circuit board 20 one after another in the same way, but after the printed circuit board 20 is set at a predetermined position on the work table 19, it is fixed in the same place until all the attachments are completed. Not moved.

Further, the tube 172 is fixed to the cutter brackets 63 and 84 by appropriate means, and an optical fiber is introduced into these, and one end of this optical fiber is connected to a light emitting device (not shown). has been done.

In the above-mentioned example, the movable cutter device 4b is inserted into the mounting hole 78 of the printed circuit board 20 and the electronic component 7 protrudes toward the back side thereof.
It is provided so that it can be moved in two directions: a direction parallel to the line connecting the pair of lead wires 73 of 2, and a direction orthogonal to this direction in the same plane, so that it can be bent inward and outward. In the present invention, the movable cutter device 4b may be installed so that it can move only in a direction parallel to the line connecting the pair of lead wires 73 of the component 72, and be provided so that it can only bend inward. In this case, for example, as shown in FIG. 16, the cutter bracket 84 may be fixed to the cutter base 83.

Further, the lead wire discharging device 153 is connected to the skirt 1.
