Abstract

PURPOSE:To prevent inspection effect from dropping even when a switch is frequently changed over by installing a change over mechanism which changes over a slide switch on a printed board. CONSTITUTION:Continuity test is carried out to examine the continuity of a printed board 1 with a continuity jig pin 16 in an inspection station 3 and an ON/OFF test is further carried out to examine the on/off performance of a dip switch 100 by changing over the dip switch 100 with a change-over mechanism 30.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to the following: Among the components mounted on a printed circuit board,
The present invention relates to an automatic adjustment inspection device for printed circuit boards, an orthogonal robot, and a CIM that automatically adjust and inspect parts that require adjustment.

[Prior Art] Printed circuit boards used in electrical equipment, control equipment, etc. require mote switching, such as slide switches, or rotation adjustment elements, which are adjusted by rotating. When mounting the necessary components, after all components are mounted and wired, the components are adjusted using an automatic adjustment inspection device for printed circuit boards.
I'm trying to get it checked.

Various conventional automatic adjustment inspection devices for printed circuit boards have been proposed and put into practical use, among which the following are described.

The first conventional technology is to turn on a printed circuit board during inspection, then check the power supply to the printed circuit board and the input/output of various signal lines, and then drive the variable volume resistor as a rotation adjustment element. The operator sets the mote of the printed circuit board by turning it to a predetermined position using a bit and then changing the dip switch as a slide switch.

When checking the power supply and signal lines, a connector of a circuit on the inspection device side is connected to a connector on the printed circuit board, or a conductive pin is pressed against a terminal portion or a through-hole portion on the back side of the printed circuit board. Sometimes, the operator can easily push the conduction pins using a conduction pin jig that is specially designed for each model of printed circuit board, and the conduction pin jig should be changed and used according to the test model. There is.

On the other hand, as a second prior art, for example, Japanese Patent Laid-Open No. 55-1
As shown in Publication No. 48498, Publication No. 55-1500300, Publication No. 62-O 3098, and Publication No. 62135QQQ, a driver bit is fitted into a rotation adjustment element such as a variable volume resistor, and a variable value is set in the energized state. There is a device that adjusts the value to a set value. In this case, at the time of adjustment, setting data is stored in the device in advance, as shown in Japanese Patent Application Laid-Open No. 55-150300, and the setting value is adjusted while monitoring the variable amount accordingly. There is.

7 Also, the tri-babit part is published in Japanese Patent Application Laid-Open No. 55-148494.
As shown in the publication, a clutch mechanism is provided to prevent the element under test from being destroyed due to excessive load in the rotational direction, and a pressure sensor is also provided to prevent excessive load in the axial direction of the driver bit. Some devices are designed so that the pressure sensor does not press the element to be tested when the force is generated.

[Problems to be Solved by the Invention] By the way, the prior art described above does not take into account the following points.

(1) That is, in the first prior art, the mode switching of the slide switch is performed manually, so when a dip switch is used as the slide switch, the switch part is very small, about 1 river angle. Therefore, if you try to switch the switch part manually, you will need a tool with a narrow tip, such as a screwdriver, which makes it difficult to work with, and if you try to switch it frequently, the inspection efficiency will drop significantly. be.

In order to solve this problem, it is easy to think of shorting the terminals of the dip switch to perform the electrical switching operation instead of manually switching the dip switch. Since the switch is not moved directly, there is a problem in that it is not possible to detect abnormalities in the switch body, such as poor contact between contacts.

(2) In addition, in the first conventional technology, a conduction pin jig is used as a means for energizing the printed circuit board, but this conduction pin jig needs to be replaced depending on the type of printed circuit board being inspected. There is a problem in that it requires human intervention and therefore cannot be fully automated.

(3) In addition, dust such as flux residue adheres to the tip of the conduction pin jig, which can be a major cause of poor conduction. Therefore, the operator must remove the dust with a brush, etc. There's a problem.

(4) Furthermore, in the first conventional technology, when checking whether the orientation of the connector mounted on the printed circuit board is correct, the operator visually checks it; This can lead to product malfunctions and damage due to oversights.

(5) Depending on the rotation adjustment element, there may be a slight angle return called springback between the pit m91 angle and the angle when the bit is unloaded.
! Depending on the I adjustment level, the springback may have a large effect. However, in the first and second prior art techniques, the springback is not taken into consideration, and therefore, there is a problem in that even if the automatic adjustment is performed, an error due to the springback is included.

(6) Among the second conventional techniques, JP-A-55-14849
The one in Publication No. 8 is rotary li! Although there is a means to prevent overload that occurs in the rotational direction when adjusting the adjusting element, if the rotating adjusting element stops rotating, the allowable torque amount for stopping rotation varies depending on the type of element. In order to be able to change the amount of allowable torque depending on the type of element, it is necessary to replace the wave-shaped ring-shaped spring, or to correspond to this, it is necessary to replace the tri-babit itself, which requires replacement work. There's a problem.

With this switching mechanism, the switch section can be reliably and automatically switched, inspection efficiency can be increased, and the above objective (a) can be achieved. Furthermore, since the switch section is directly switched, it is possible to detect abnormalities in the switch itself, such as poor contact of contacts.

The frame 34 is approximately U-shaped, and the bracket l-3

It has a slider 44 and a wedge-shaped slider 45 attached to the rod of each cylinder 43 and disposed between the guide 39 and each mode switching claw 32. Then, when the two cylinders 42 are driven, the slider 44 of the rod descends along the guide 39 and resists the elastic force of the spring 41 to open the upper end of the reset claw 3 and open the tapered part of the reset claw 31. By rotating the tip around the pin 37 toward the mower 00-mode switching pawl 32, the switch part j00a of the dip switch 100 is turned.

In order to confirm whether the switch section 100 of the dip switch 100 is on or off, each lead of the dip switch 100 is brought into contact with the dip switch 100, as shown in FIG. 6 (1).

Therefore, the probe pin 48 is wired so that the current flowing through each lead can be detected when it comes into contact with the lead 100b. Each probe pin 48 is made of a spring material or the like, and when it comes into contact with each lead lOOb, the probe pin 48 is
Even if 00b is deformed, the elastic force of the spring increases the contact force so that it can reliably contact each lead 100b. Therefore, each beam of these probe pins 48 -+:

The friction torque between the third member 64 and the second member 63 is greater than the friction torque between the third member 64 and the second member 63, and the third member 64 and the second member If slippage occurs in the meshing portion between the upper case 59 and the member 63, and a torque exceeding the allowable rotation stop torque of the variable resistor 200 acts on the upper case 59 when adjusting the rotation of the upper case 59 in the counterclockwise direction, the torque is the first member 6
The friction torque between the second and third members 64 is greater than that between the first member 62 and the third member 64 by overcoming the engaging part of the third member 64 while resisting the engaging part of the first member 62 or the spring force of the spring 66. Slippage occurs in the meshing portion with the third member 64, thus preventing the driver bit 61 from rotating with a torque exceeding the allowable torque.

Further, the adjustment driver device 50 includes a driver bit 6
In order to ensure that J fits into the variable resistor 200, in addition to connecting the cantering shaft 57 and the upper case 59 with the flexible coupling 58 as described above, the driver bit 61 is urged toward its tip. A compression spring 71 is provided.

That is, the compression spring 71 consists of a coil spring installed between the upper end of the driver bit 6 and the bolt 73 inside a cylinder 72 fixed to the lower case 60, and the compression spring 71 is variable depending on the spring force. When the height of the resistor 200 changes depending on the type, the spring force causes the driver bit 61- to move up and down in the cylinder 72 to fit the groove 200a of the variable resistor 200 in an appropriate manner. It is made to fit together by force. Therefore, the driver bit 61 and the variable resistor 200#
If a radial deviation occurs in j, the deviation is absorbed by the flexible coupling 58, and if an axial deviation occurs between the two, the deviation is absorbed by the spring force of the compression spring 71. We are making it possible to do so.

The bolts 73 are used to fix the cylinder 72 to the lower case 60, and the cylinder 72 is attached by a bit receiver 74 so that the driver bit 6e can be moved in the axial direction.

Further, the adjustment driver device 50 includes springback correction means for adjusting the amount of rotation of the rotation adjustment element by an amount corresponding to a predetermined amount of variation due to springback. The springback correction means, as shown in FIG. 9, calculates the amount of springback of the variable resistor 200 in advance using a computer 76, and based on a command from the computer 76, the adjustment unit 75 calculates the amount of springback when the stepping motor 52 is driven. Adjustment is made by rotating the variable resistor 200 an additional amount corresponding to the amount of springback determined based on the command from the personal computer 76.

At this time, there are, for example, the following two al111 methods that take into consideration the amount of springback. Note that the rotation angle of the variable resistor 200 used here is 3.
It rotates at an angle of less than 60 degrees, and rotates clockwise from its rotation start position to its rotation end position.

For that (-), first fit the tip of the driver bit 1-6]- into the groove 200a of the variable resistor 200, and then hit the driver bit 6e against the stopper that is the starting point of rotation in the variable resistor 200. Turn counterclockwise until
At this time, the current value flowing through the stepping motor 52 is monitored by the adjustment units 1 to 75, and the rotation of the driver bit 61 is controlled by the variable resistor 2.
When the stepper motor 52 hits the stopper 00, the load on the stepping motor 52 increases and the current value increases, so when the current value reaches a certain value, the adjustment unit 75 turns off the motor drive circuit to stop the motor 52. Further, the current value set by the personal computer 76 is selected to be lower than the current value generated when the rotation stop torque of the variable resistor 200 is lower than the allowable rotation torque, and larger than the current value generated at the required rotation torque. Initial settings are performed in this way.

Then, the stepping motor 5 is adjusted by the adjustment unit 61.
The driver bit 61 is rotated clockwise through 2, and the current value at that time is 1! The stepping motor 52 is monitored by the II adjustment unit 75, and when the rotation of the driver bit 61 reaches a set value predetermined by the personal computer 76, the stepping motor 52 is stopped. In this case, adjustment unit 75
is the frequency of the rotating variable resistor 200 according to the command from the computer 76.

Variable resistor 20 by detecting DC voltage and angle
It is designed to adjust to 0.

Next, when the variable resistor 200 is stopped and the variable resistor 200 is raised by raising the driver pin 1 to open the variable resistor 200, the variable resistor 200 returns slightly counterclockwise due to springback, as shown in FIG. ΔO occurs, and the adjustment value fluctuates by ΔR. This variation amount ΔR becomes the springback amount, so at that time, the variation amount ΔR
is determined by the adjustment unit 75. After storing the amount of variation ΔR with respect to the predetermined adjustment value R in the personal computer 76, the driver bit 61 is lowered again, and the driver bit 61 is further fitted into the groove 200a of the variable resistor 200. 200 to the stopper, which is the starting position, and then rotate the variable resistor 200 clockwise with a rotation amount equal to the set value R plus the variation amount ΔR, thereby taking into account the amount of springback. We are making adjustments accordingly.

As for (d), adjust the adjustment unit 75 in advance.

Variation amount Δ from the setting amount for the rotation angle of the variable resistor 200
R is stored as experimental data, and after initial setting by turning the variable resistor 200 to the rotation starting position in the same manner as described above, the driver bit 61 is actually set.
By rotating the variable resistor 200 clockwise and detecting the number of steps of the stepping motor 52 at that time,
Alternatively, the variable resistor 2 can be detected by position detection means such as an encoder.
By detecting the rotation angle of 00, adjustment is made by adding a variation amount ΔR obtained in advance from experimental data to the set amount R.

Therefore, the amount of variation ΔR due to springback of the variable resistor 200 to be adjusted is determined in advance, and the amount of variation ΔR is adjusted by adding the rotation amount to the set value R at the time of adjustment.

On the other hand, a discrimination inspection device 80 for determining the orientation of the connector 300 includes eight fins movable in the direction of the connector 300, as shown in FIGS. The orientation of the connector 300 is determined depending on whether or not it is inserted into the slit 300a.

To explain in more detail, first, connector 3 used here.
00 is one in which a slit 300a is provided in one wall of the periphery. Then, the discrimination inspection device 80
A fin 81 is attached to the tip of a rod 82, and the rod 82 is attached to a frame 83 fixed to the operating shaft 10a of the hunt 10 so as to be movable in the direction of the connector 300. A compression spring 86 inserted through the rod 82 is interposed between a spring receiver 84 fixed to the bottom of the frame 83 and a spring receiver 85 fixed to the lower part of the rod 82.
Due to the spring force of the compression spring 86, the fin 8'' is pressed against the connector 3.
It is biased in the 00 direction.

In this case, the operating axis ]-0a is constituted by a screw shaft. Further, a limit switch 87 is installed on the upper part of the frame 83 at a position facing the rod 83, and the striker 88 thereof is arranged so as to be in contact with the upper end of the rod 83 while remaining in the off state, for example.

As shown in FIG.
When the connector 300 is moved toward the connector 300, the fin 81 is inserted into the slit 300a of the connector 300, thereby determining that the connector 300 is in the normal position, and at this time, as shown in FIG. When the fin 81 hits the upper end of the connector 300, the rod 82 resists the spring force of the compression spring 86 and rises in the direction indicated by the arrow shown by the broken line with respect to the frame 83, and the upper end of the frame 83 hits the striker of the limit switch 87. By pressing 88 to turn it on, it is determined that the connector 300 is in the reverse position. Therefore, the fins 81 and the rods 82 are prevented from rotating around the axis.

Note that when the limit switch 87 is turned on, the operation axis 1. of the hand 10 is immediately turned on. It is preferable to prevent the connector 300 from being damaged by the fins 81 when Oa is stopped and raised.

Further, the fin 81 has a cross shape, and the fin 81 has a cross shape.
As shown in the figure, when the connectors 300 are arranged in four directions on the printed circuit board 1, the orientation of the connectors 300 can be determined without changing the position of the fins 81.

Therefore, as shown in FIG. 14, the automatic adjustment inspection device of this embodiment inspects the continuity between the printer 1 and the substrate 1 using the conduction pin jig 16 at the inspection station 3, and switches the dip switch 100 using the switching mechanism 30. Then, the on/off state of the dip switch 100 is checked, and the adjustment driver device 50 adjusts the rotation of the variable resistor 200 to vJ.

Furthermore, the orientation of the connector 300 is inspected by the discrimination inspection device 80.

And those conduction pin jigs 16. Switching mechanism 30.
As shown in FIG. 15, the adjustment driver device 502 and the discrimination/inspection device 80 are designed so that the entire device is controlled in various ways according to a predetermined program based on commands from a personal computer 76. Therefore, this automatic adjustment inspection device includes a measurement unit 90 for measuring each inspection point of the printed circuit board 1, an adjustment section of the hand 10, and an adjustment driver device 5.
Adjustment units 1 to 75 that control 0 and inspection stage 43
- ~44- Control of controllers 1 to rollers 9 in controller 3, loader 4 for loading substrates and unloader 5 for unloading substrates in transport path 2
A sequencer 9 that controls the drive unit 92 that drives each of the
3, a jig setup mechanism A, and a personal computer 76 that integrally manages these via GPIB. In this case, a serial I/F is provided between the personal computer 76 and the conductive pin jig 16 to enable communication between the two. Also connected to the personal computer 76 are a barcode reader 94 for reading information on the model of the printed circuit board 1, and a printer 95 for printing out inspection results.

Since the automatic adjustment inspection device of the embodiment has the above-mentioned configuration, its operation will be explained next.

First, in FIG. 1, a magazine rack containing printed circuit boards 1 to be inspected is set on the board loading loader 4 on the transport path 2, and the printed circuit boards 1 are loaded from the magazine rack.
is sent out onto the conveyance path 2 and carried into the inspection station 3. At the inspection station 3, the barcode affixed to the printer 1 to the board 1 in advance is read by the barcode reader 81, and the read model information is read. is sent to the computer 76.

The personal computer 76 selects inspection software for the target model to be inspected based on the information read by the barcode reader 81, and prepares for inspection according to the selected inspection software. At that time, the jig setup mechanism A takes out the conductive pin jig 16 of the type corresponding to the type of printed circuit board 1 to be inspected from the stocker 19 and transfers it to the transfer table 2 as shown in FIG. The conductive pin jig 16 is transferred to the inspection position of the inspection station 3 by the movement of the conveyor table 21, and then the conductive pin jig]-6 is connected to the apparatus side by the electric switch section 24. Furthermore, when the conduction pin jig 16 is transported to the inspection station 3, dust attached to the pins of the conduction pin jig 16 is removed by a rotary brush 25 and a vacuum pump 26, which are self-cleaning means.

On the other hand, in the inspection station 3, the presser bar 46↓3 is lowered by the drive of the cylinder 1 of the presser unit, presses the printed circuit board 1 against the conductive pin jig 16 as shown in FIG. Accurately position the pin jig ↓6.This allows you to select the type of conduction pin jig 1 that corresponds to the printed circuit board 1 to be inspected.
6 can be set automatically.

When the inspection preparation is completed in this way, the inspection station 3 moves the hand 10 in the X direction, Y direction, and Z direction and positions it at a desired position, thereby inspecting the components mounted on the printed circuit board 1, that is, sliding the hand 10. Inspection of the dip switch 1 and OO as switches, the variable resistor 200° connector 300 as a rotation adjustment element is started.

For example, when inspecting the dip switch 100,
When the switching mechanism 30 is positioned on the dip switch 100 by the movement of the hand 0, the switching mechanism 30 switches the switch portion of the dip switch 100. In this case, in order to first turn off all switch parts of the dip switch 100, the two cylinders 42 of the switching mechanism 30 are driven to operate the reset claw 31 as shown in FIG. is turned off by switching the switch portions of the dip switch 100 all at once.

Next, select a desired cylinder 4 among the four cylinders 43.
3, the corresponding mode switching claw 32 operates, and the mode switching claw 32 switches the corresponding switch section, thereby selectively turning on the desired switch section. In addition, when changing the switching mode,
After turning off all the switch sections by operating the reset claw 31 again, the desired mode can be set by operating the desired mode switching claw 32 again.

In this way, by reducing the number of reset claws 31 to one, not only can the number of claws used as the switching mechanism 30 be reduced, but also the number of cylinders 42 and 43 for driving the switching mechanism 30 can be reduced. The switching mechanism 30 can be downsized.

Moreover, the reset claw 31. The mode switching claws 3247-48 have a shorter length from the point of contact with the slider 44 to the fulcrum of the spring 41 than the length from the point of action at their tip to the fulcrum of the spring 41. .2.43 driving force can be reduced,
It can be operated reliably with a small driving force, and further miniaturization can be achieved.

In addition, to check whether the switch part of the dip switch 100 is on or off, please use the probe pin 4 as shown in FIG. 6(b).
8 to each lead 100b of the dip switch 100.
This is done by contacting the probe pin 48 and checking the electrical signal of the probe pin 48 at that time. In this case, probe pin 48
Since each lead is made of spring material etc.
Even if the lead 100b is deformed by being pressed against the lead 100b, the contact can be made reliably, and when the pressure against the lead 100b is released, the lead 100b can return to its original shape.

When inspecting the variable resistor 200, as shown in FIG.
0 is positioned on the variable resistor 200, the hand 1
0 first lowers the driver bit 61 of the adjusting driver device 50 and fits its tip into the groove 200a of the variable resistor 200.

At this time, since the drive shaft 57 of the adjustment driver bit 50 and the second case 59 are connected by the flexible coupling 58, it is possible to absorb the deviation of the driver bit 61 in the radial direction with respect to the groove 200a. Since the compression spring 71 that biases the driver bit 61 is provided, the driver bit 61 is pressed against the groove 200a.
can absorb the axial deviation of the driver bit 6.
1 can be tolerated, so the driver bit 61 can be reliably fitted into the groove 200a.

Then, the driver bit 61 is connected to the groove 2 of the variable resistor 200.
00a, the stepping motor 52 of the adjustment driver device 50 is rotated, the variable resistor 200 is rotated counterclockwise to the starting position of the rotation direction using the driver bit 6↓, and then stopped. Then, the variable resistor 200 is rotated by the driver bit 61 to a desired adjustment position.

In this case, the adjustment lever device 50 additionally rotates by the amount of variation ΔR due to the springback of the variable resistor 200, and is provided with a springback means for adjusting the springback to a predetermined setting value R. Adjustments can be made taking into account the amount of variation ΔR caused by the adjustment, and therefore, even if adjustments are made in the conventional manner, the adjustment values will not change due to springback, and adverse effects can be prevented. Furthermore, during adjustment, since the amount of adjustment is monitored by the adjustment unit 75 of the adjustment driver device 50, there is no need to consider the play between the driver pitch (-61) and the groove 20Oa of the variable resistor 200.

Further, when a torque exceeding the allowable rotation stop torque of the variable resistor 200 is applied to the driver bit 61 due to runaway of the stepping motor 52, etc., the adjustment driver bit 50 adjusts as shown in FIGS. 7 and 8. It has a torque limiter mechanism composed of third members 62, 63, 64, a support shaft 65, and a spring 66, and for example, when a torque exceeding the allowable rotation stop torque is applied in a clockwise direction,
Slippage occurs in the meshing portion between the third member 64 and the second member 63, causing the meshing of both 63 and 64 to be released, and a torque exceeding the allowable rotation stop torque in the counterclockwise direction is generated. When this action occurs, the meshing portion between the first member 62 and the third member 64, which has slipped, will be disengaged, causing the driver bit 61 to exceed the allowable rotation stop torque. Prevents rotation due to torque. Therefore, since the torque exceeding the allowable rotation stop torque of the driver bit 61 does not act on the variable resistor 200, it is possible to deal with various rotation adjustment elements.

When inspecting the orientation of the connector 300, the discrimination inspection device 80 moves the connector 300 by moving the hand 10.
00, the fin 81 is moved to the connector 30 by driving the operating axis 1-Oa of the hand 10.
Move towards 0.

1 2- At that time, if the connector 300 is in the correct orientation,
As shown in the first diagram, the fin 81 is inserted into the slit 300a, and the striker 88 of the limit switch 87
Since the connector 300 does not operate, it can be determined that the connector 300 is in the normal position. Furthermore, if the connector 300 is not in the correct orientation, the fins 81 will not be inserted into the slits 300a, and the connector 300 will not be inserted into the slit 300a, as shown in FIG.
0, the rod 82 rises, and the rod 82 pushes the striker 88 of the limit switch 87 to turn it on, thereby making it possible to determine that the orientation of the connector 300 is not the normal orientation.

Since the fin 81 has a cross shape, the connector 30
As shown in FIG. 13, even if the connectors 300 are arranged in various ways on all four sides of the printer 1 to the board 1''2, the orientation of the connector 300 can be reliably determined without changing the position of the fins 81.

When the various inspections are completed in this manner, the cylinder 11 at the inspection station 3 is raised by 1" to release the pressing of the printed circuit board 1 against the conduction pin jig 1-6 by the presser bar 13, and to release the printed circuit board 1 The inspection information of measurement unit 90° adjustment unit 1 to 75. The data is sent to a personal computer 76 by the conduction bin jig 16, and the personal computer 76 judges the inspection data to send out the printed circuit boards 1- that have passed the inspection via the conveyance path 2 to the unloader 5 for carrying out the board, and also to send out the printed circuit boards 1- that have passed the inspection to the unloader 5 for unloading the substrates. The printed circuit boards 1 are sent to the ejection buffer 6, and the defective data for the printed circuit boards 1 that are defective in the inspection are printed out using a printer, etc., thereby completing the inspection of the - number of printed circuit boards 1.

In the illustrated embodiment, a jig setup mechanism A is provided in the hand 10 of the inspection station 3 of the automatic adjustment inspection device.

Switching mechanism 30. Adjustment driver device 50. Although an example is shown in which the discriminative inspection device 80 is provided, it is possible to apply the hand to an orthogonal robot configured to have a self-propelling function and to be movable in each of the X direction, Y direction, and Z direction. This not only facilitates teaching for inspection, but also allows for easy handling of printed circuit boards in which mounted components are mounted in different positions.

In addition, although the above-mentioned inspection shows an example in which various components mounted on the printed circuit board 1 are inspected in advance, it is also possible to perform the mounting, soldering, inspection, etc. of various components on the printed circuit board in an integrated manner.

Solder the leads of the components by melting them.

Then, in a cleaning step 105, the board is cleaned to wash away the residue of the flux used in the soldering process 104. In the component insertion step 1-06, the leads of the lead components supplied from the component management equipment 1.01 are inserted into the through-holes of the board, etc., and in flow soldering 107, the board is soldered with the solder in the solder bath. After the lead components are soldered, a cleaning step 108 washes away the flux residue used during the soldering in step 107, and an appearance inspection step 109 checks to see if there are any damaged parts on the board or parts or if there are any disconnections at the connection points. 9 circuit components of a board on which components were visually inspected and components were mounted in an in-circuit tester step 110.

Check soldering, etc. Thereafter, the jig setup mechanism A and the switching mechanism 30 . The inspection is performed by the adjustment driver equipment R502 discrimination inspection device 80.

In this way, by using the automatic inspection function in the consistent production process from raw boards to producing printed circuit boards with components mounted on them, it is possible to cope with the shift to CIM.
