Next, on one surface of a guide member 7c that slidably guides a driver portion 7g, which will be described later, is installed a straight-moving actuator 7d that is a straight-moving air cylinder that moves straight in parallel to the axial direction of the driver portion. A connecting member 7f having a predetermined length is attached to the side surface so as to extend to the side opposite to the rectilinear actuator 7d, and the connecting member 7f is fixed to the rotary shaft 7b of the rotary actuator 7a. Next, the driver portion 7g is provided with a drive portion 7i composed of an electric motor at a rear end portion of a cylindrical member 7h that slides straight on the inner surface of the circular guide of the guide member 7c, and at the front end portion thereof.

m is fixed, and the bracket 7m is connected to the shaft 7n of the linear actuator 7d. Therefore, when the rectilinear actuator 7d is driven, the driver portion 7g rectilinearly advances and retracts via the bracket 7m. The adjusting mechanism 7 is configured in this way, and drives the rotary actuator 7a to rotate the entire driver portion 7g attached to the linear actuator 7d. When the substrate holding member 5, that is, the XY table 6 is lowered and the rotary actuator 7a is driven to rotate 90 °, the height of the rotary bit 7k is set to the substrate as shown in FIG. 3B. The length of the connecting member 7f is determined so as to be equal to the height of the insertion hole 2g of the adjustment element 2f having the insertion hole in the direction parallel to the surface. Further, in the state of FIG. 3B, in FIG.

Next, the operation of this embodiment will be described.

In FIG. 2, when the switch of the electronic circuit board adjusting device 1 is turned on, the board 2 is carried in by the conveyor 3 and stopped at a predetermined position by a stopper (not shown), and the loading of the board is detected by a sensor (not shown). It Then,
The substrate pressing member 5 descends together with the cylinder shaft 5d, and the rod-shaped projections 5b press and fix the substrate 2 from above. Note that the XY table 6 also descends as the substrate pressing member 5 descends. Further, the pin contact member 8 rises, the pins come into contact with the substrate 2 from the back surface, and the electronic components on the substrate and the measuring means are electrically connected.

Next, according to a command from the control section of the electronic circuit board adjusting device 1, adjustment elements such as variable resistors, capacitors, coils, etc. at respective positions on the board are adjusted.

First, the insertion hole 2b is formed in the direction perpendicular to the substrate surface.
When adjusting a certain adjusting element 2a, as shown in FIG. 3A, the rotary actuator 7a is not driven,
That is, with the rotation axis of the rotation bit 7k being perpendicular to the substrate surface, the XY table 6 is driven to position the rotation bit 7k axis in the insertion hole 2b. Then, the linear actuator 7d is driven. Then, the driver portion 7g goes down between the beams 5c and 5c, descends, inserts the rotating bit 7k into the insertion hole 2b, and the driving portion 7i rotates the rotating bit 7k.
Is rotated by a predetermined amount to adjust the adjusting element 2a. After the adjustment, the linear actuator 7d is driven to retract the driver portion 7g, and if there is an adjustment element 2a having the insertion hole portion 2 in the direction perpendicular to the substrate surface, the XY table 6 is similarly moved. By driving, the rotary shaft of the rotary bit 7k is made to face the insertion hole 2b, and adjustment is performed.

2 to the right end position in FIG. 2 and the Y table is driven to equalize the Y coordinates of the rotary bit 7k of the adjusting mechanism 7 and the insertion hole 2g of the adjusting element 2f at the right end of FIG. Then, in this state, when the rotary actuator 7a is driven to rotate 90 °, the rotary bit 7k and the insertion hole 2g face each other as shown in FIG. 3 (b). Therefore, when the linear actuator 7d is driven to move the driver portion 7g forward, or the X table is driven to move the Y table 6c to the left in FIG. 2, the rotary bit 7k causes the outer frame 5a of the substrate pressing member to move. Since it is inserted into the insertion hole 2b through the lower side, the drive unit 7i rotates the rotary bit 7k by a predetermined amount to adjust the adjusting element 2f. Board 2
2 has another adjusting element 2f at the right end thereof, the linear actuator 7d is driven to move the driver portion 7g backward, or the X table is driven to move the Y table 6c to the right in FIG. After that, the Y table is driven to equalize the Y coordinates of the rotary bit 7k and its insertion hole 2g,
The driver portion 7g is moved forward or the Y table 6c is moved to the left to make an adjustment. In this way, it is possible to adjust the adjusting element 2f having the insertion hole portion in the direction parallel to the board surface, which is mounted at various positions on the right end portion of the board in FIG.

, The substrate 2 is unloaded by the conveyor 3, a new substrate 2 is loaded into the apparatus 1, and the adjustment element is adjusted in the same manner as described above.

In the present embodiment, the rotary actuator 7
It is assumed that the adjustment element 2a having the insertion hole 2b in the direction parallel to the substrate surface is adjusted by driving a and is rotated by 90 °, but in the case of the adjustment element having the insertion hole portion obliquely to the substrate surface. Can be adjusted by driving and rotating the rotary actuator 7a by that angle.

A second adjusting mechanism 12 for adjusting an adjusting element 2f is provided.

The first adjusting mechanism 11 is the same as the conventional one, that is, the guide member 11c is fixed to the carriage 6d with the guide hole direction perpendicular to the substrate surface, and the guide hole is formed in the guide hole. The driver portion 11g is slidably guided. Further, the driver portion 11g is connected to the first linear actuator 11d fixed to the guide member 11c by the bracket 11m, and the first linear actuator 1

Next, the second adjusting mechanism 12 includes the guide member 1
2c is fixed to the carriage 6d with the guide hole direction perpendicular to the substrate surface.
p is slidably fitted. The guide rod 12p is the second linear actuator 1 fixed to the guide member 12c.
It is connected to 2d by a bracket 12m, and moves in the vertical direction by driving the second rectilinear actuator 12d. Next, the driver portion 12g has a structure in which a drive portion 12i composed of an electric motor and a rotary bit 12k are connected by a drive shaft (not shown) passing through the cylindrical cover 12h. Since the driver portion 12g does not slide, The length is getting shorter. And the axial direction of the rotary bit 12k is X
The cylindrical cover 12h is fixed to the bracket 12m in the direction. Therefore, the second linear actuator 12
When d is driven, the driver unit 12g causes the rotary bit 12
The axial direction of k is set to the X direction, and it moves back and forth in the vertical direction. It should be noted that when the carriage 6d is moving above the substrate, the driver portion 12g is raised so that the second adjusting mechanism 12 does not hit an electronic component or the like on the substrate.

The other structure is the same as that of the first embodiment, and the explanation is omitted.

Next, the operation of this embodiment will be described.

When adjusting the adjusting element 2a having the insertion hole 2b in the direction perpendicular to the substrate surface, as shown in FIG.

(C)).

[0037]

Since the present invention is constructed as described above,
With one XY table, it is possible to adjust the adjustment element having no insertion hole in the direction perpendicular to the substrate surface, which simplifies the structure of the device and reduces the cost of the device.

Further, since it is not necessary to limit the arrangement position of the adjusting element having no insertion hole portion in the direction perpendicular to the substrate surface to a fixed position, the degree of freedom in the design of the substrate is increased, and therefore the design of the product incorporating this is increased. It is possible to greatly increase the degree of freedom.
