That is, the timing belt 430 and the lifting plate 450 are not linked directly but are interlocked with each other through the clamp 460.

Meanwhile, an upper and lower limit sensor 550 may be installed at one side of the vertical movement unit 400 to sense the vertical movement of the vertical movement unit 400. The upper and lower limit sensor 550 senses the distance that the vertical movement unit 400 is moved up and down so that the vertical movement unit 400 does not deviate from the designated range.

The load inspecting unit 500 includes a spring pin 510, a load cell 520, a load cell broker 530, and a left and right feed motor 540. The load inspecting unit 500 measures a load applied to the dome switch 12 .

The spring pin 510 is provided on the upper side of the seating block 200 so as to be movable left and right to press the upper surface of the dome switch 12. The spring pin 510 has a cylindrical shape and is formed with a spring to have elasticity at its end. That is, when the end of the spring pin 510 comes into contact with the upper surface of the dome switch 12, the spring is compressed. When the end of the spring pin 510 is separated from the dome switch 12, .

A load cell 520 is provided at an upper end of the spring pin 510. The load cell 520 is coupled to the upper end of the spring pin 510 and is a portion that interlocks with the spring pin 510 and measures a load applied to the dome switch 12. [ That is, the spring pin 510 functions to measure a load applied by pressing the upper surface of the dome switch 12. [

A load cell broker 530 is provided at an upper end of the load cell 520. The load cell broker 530 is provided to be movable laterally along the front surface of the lifting plate 450.

2, an inspection member 216 for inspecting components provided in the dome switch assembly 10, as well as the dome switch 12 and the connector 14, may be mounted on the upper end of the cover block 210. [ May be further included.

For example, the inspection member 216 may include a member for inspecting a sensor that senses a distance at the time of photographing using a camera provided in the smartphone, a flash (not shown) A member for inspecting the LED, and the like. When the sensor for detecting the distance is inspected on the inspection member 216, the reflection plate 600 may be further provided to reflect the wavelength of the infrared rays. The reflection plate 600 is fixed by a support stand 602 vertically installed upward from the work table 110.

Hereinafter, the operation of the dome switch load tester according to the present invention will be described with reference to the accompanying drawings.

First, when the main body case 100 is powered on for the first time, the seating block 200 is set to move a certain distance to the right side (in FIG. 2) by the horizontal movement unit 300. More specifically, the seating block 200 moves in the direction of the right side, that is, the direction in which the holding member 120 is formed, as shown in FIG. This is a process in which the dome switch assembly 10 is moved to a position easy to inspect because the inspection positions are different according to the dome switch assembly 10 having various sizes and shapes.

Thereby, the inspection preparation procedure is completed, and then the vertical moving part 400 is driven.

The vertical movement unit 400 first drives the rotary shaft 412 by forward and reverse rotation of the stepping motor 410 and rotates the timing belt 430 spanning the pulley 420 and the idler 440, The clamp 460 and the lifting plate 450 interlocked with the timing belt 430 are lifted up and down.

When the lifting plate 450 is lowered toward the work table 110, the inspection is started. On the other hand, when the lifting plate 450 is lifted up the work table 110, the inspection is completed.

More specifically, as the lifting plate 450 is lowered, the spring pin 510 gradually approaches the upper surface of the dome switch 12. Then, when the spring pin 510 and the dome switch 12 are brought into contact with each other, the load applied to the dome switch 12 is measured through the load cell 520. Then, the spring pin 510 is moved toward the next dome switch 12 formed side by side on the side of the dome switch 12 that has been inspected.

At this time, the screw 542 is moved to the left (in FIG. 2) by the driving of the right and left feed motor 540 so that the load cell broker 530 is moved to the left along the front surface of the lift plate 450. In addition, the load cell 520 and the spring pin 510 are also moved to the left side. Here, the measured load value measured through the load cell 520 is transmitted to the controller through the connector 14.

After the inspection of the plurality of dome switches 12 is completed, the left and right feed motors 540 are driven to rotate the screws 542 Is moved to the right (in FIG. 2), the load cell broker 530 is moved to the right along the front surface of the lifting plate 450. In addition, the load cell 520 and the spring pin 510 are moved to the right together. Then, the seating block 200 is returned to the initial position, and the measurement values measured by the above-described procedure are output through the display panel 102.

When the dome switch assembly 10 is to be replaced, the retaining member 212, which fixes the seating block 200, is temporarily spaced apart from the seating block 200 The cover block 210 is lifted upward. Then, after removing the dome switch assembly 10 which is already seated, the new dome switch assembly 10 is seated.

As described above, the dome switch load tester according to the present invention can obtain accurate and detailed load measurement values by simply placing the dome switch assembly 10, which is an object to be inspected, on the seating block 200 and pressing the operation button 101 with a simple operation The present invention can be said to be useful.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
