[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic adjustment device that automatically performs mechanical adjustment work of a trimmer capacitor used for voltage adjustment, for example.

[0002]

[Prior art]

 In the past, adjusting this type of trimmer capacitor was done manually, relying on human labor. That is, the operation of rotating the adjusting portion by an arbitrary amount so as to obtain a predetermined voltage value while pressing the minus driver against the adjusting portion of the trimmer capacitor is performed while checking the operation with human eyes.

[0003]

[Problems to be solved by the device]

 However, with this type of manual work method, uneven adjustment occurs due to individual differences, and sufficient quality control cannot be performed.Moreover, when adjusting a large number of trimmer capacitors, it takes a lot of work time to rely on manual work. There was a problem that sufficient productivity could not be expected.

In view of the above problems, the present invention stably drives the adjustment driver, obtains a reliable desired rotation amount, and enables accurate positioning of the trimmer capacitor, which is the workpiece, and the adjustment driver. It is an object of the present invention to provide an assembly as an automatic adjustment device, that is, an automatic adjustment device for a trimmer capacitor assembled as a single cell.

[0005]

[Means for Solving the Problems]

 The present invention aims to solve the above-mentioned problems, and in order to achieve the purpose, a trimmer capacitor, an adjustment driver for adjusting the electrical capacity of the trimmer capacitor, and a driving means for rotating the adjustment driver. The present invention is characterized in that it comprises a positioning means for controlling the position of the adjusting driver in the horizontal plane and a control means for controlling the vertical position of the adjusting driver.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a front view showing the overall configuration of the automatic adjustment device, FIG. 2 is a plan view thereof, and FIG. 3 is a side view. FIG. 4 is an enlarged perspective view showing the trimmer capacitor 1 as a target work.

In the figure, 1 is a trimmer capacitor, 20 is a driver unit of the automatic adjusting device in the present invention, 3 is an adjusting driver, 4 is a stepping motor for automatic driver adjustment 5 and 6 for rotationally driving the adjusting driver. Is an ultra-low speed synchronous motor for fitting the tip of the adjusting driver 3 into the adjusting slit 1A of the trimmer capacitor 1 (that is, for positioning), and 7 is for moving the adjusting driver 3 in the vertical direction. A driver vertical drive cylinder, 8 is a driver unit mounting base for mounting the driver unit 20, 9 is a base driving cylinder for driving the driver unit mounting base 8, and 10 is the tip of the adjusting driver 3 with the trimmer capacitor 1 A detection micro switch for detecting that it is fitted into the adjustment slit 1A. It is. Further, 11 is a pulley fixed to the adjusting driver 3, 12 is a belt hung between the pulley 11 and the pulley 22 of the stepping motor 4, 13 is a bearing for the adjusting driver 3, and 14 is a driver unit 20. A Y-axis slide guide for sliding in the Y-axis direction, 15 is an X-axis slide guide for sliding the driver unit 20 in the X-axis direction, and 17 is a rotation stopper for preventing the adjusting driver 3 from rotating naturally. It's a pin.

In the automatic adjustment device having the above-described configuration, the automatic adjustment work of the trimmer capacitor 1 as shown in FIG. 1 is performed as follows.

When the trimmer capacitor 1 arranged on the workbench 21 is mounted at the position shown in the figure, the driver vertical drive cylinder 7 is lowered, whereby the tip of the adjusting driver 3 comes into contact with the upper surface of the trimmer capacitor 1. To do. At this time, the tip portion of the adjusting driver 3 does not always fit exactly into the adjusting unit 1A of the trimmer capacitor 1, but rather does not fit in many cases.

Therefore, in the next step, first, the ultra-low speed synchronous motors 5 and 6 are automatically driven so that the tip of the adjusting driver 3 and the adjusting slit 1A are just fitted, and the driver unit 20 is moved to the X-axis. The slide guide 15 and the Y-axis slide guide 14 are slid in the X-axis direction and the Y-axis direction so that the center point of the tip of the adjustment driver 3 and the center point of the adjustment slit 1A coincide with each other.

When the detection microswitch 10 detects that the center point of the tip of the adjustment driver 3 and the center point of the adjustment slit 1A match, then the stepping motor 4 is automatically driven and connected by the belt 12. The tip end of the adjustment driver 3 is fitted into the adjustment slit 1A of the trimmer capacitor 1 by rotationally driving the adjustment driver 3 provided. The tip of the adjusting driver 3 has a compliance function by a coil spring (not shown).

The fitting of the tip of the adjusting driver 3 and the adjusting slot 1A of the trimmer capacitor 1 is detected by the detection microswitch 10. That is, when the two are fitted together, the adjusting driver 3 slightly descends, so that the detection microswitch 10 detects the fitting and the preparation for adjusting the trimmer capacitor 1 is completed.

When the detection micro switch 10 detects the fitting of the tip of the adjusting driver 3 and the adjusting slit 1 A of the trimmer capacitor 1, the stepping motor 4 is automatically driven to rotate the tip of the adjusting driver 3.

A voltmeter (not shown) is connected to the trimmer capacitor 1, and the stepping motor 4 is driven until the preset electric capacitance value of the trimmer capacitor 1 is detected by the voltmeter. As a result, the electric capacity of the trimmer capacitor 1 is automatically adjusted until it reaches a predetermined value. In order to drive the adjustment driver 3 more stably, it is preferable to use, for example, a 5-phase stepping motor as the stepping motor 4.

[0016]

[Effect of device]

 As described above, according to the present invention, the mechanical adjustment work of the trimmer capacitor used as the voltage adjustment device is automatically realized, so that quick adjustment can be performed in a short time without adjustment error due to individual differences. To be achieved.
