[0020] In one embodiment, Figure 1 and Figure 2 As shown, a pad height measuring device 10 includes: a base 100, a fixing frame assembly 200 and an infrared height measuring assembly 300; the fixing frame assembly 200 is arranged on the base 100, and the fixing frame assembly 200 is used to fix and place the sound shell to be measured; the height measuring assembly includes: a slider frame 310, a sliding block 320 and an infrared rangefinder 330, the slider frame 310 is arranged on the base 100, the sliding block 320 is slidably arranged on the slider frame 310, the infrared rangefinder 330 is arranged on the sliding block 320, and the infrared rangefinder 330 is movably aligned with the fixing frame assembly 200.

[0021] Specifically, the utility model provides a pad height measuring device 10, which is provided with the fixing frame assembly 200 on the base 100, and the speaker housing can be fixed on the base 100 by the fixing frame assembly 200. Then, the sliding block 320 slides on the slider frame 310, so that the sliding block 320 can drive the infrared rangefinder 330 to align with the pad on the speaker housing, and then the infrared rangefinder 330 is used to measure the height of the pad. Since the fixing frame assembly 200 is fixedly mounted on the base 100, and the fixing frame assembly 200 can match the shape of the speaker housing to fix the speaker housing, it is only necessary to use the infrared rangefinder 330 to measure the distance between the pads, and the height of the pad compared to the height of the side of the speaker housing can be obtained, so that the height of each pad on the speaker housing can be accurately obtained. The utility model can accurately and quickly measure the height distance of the pad relative to the side of the speaker housing by using the infrared rangefinder 330, thereby improving the measurement efficiency and reducing the error.

[0022] In this embodiment, the sliding block 320 is located at one side of the slider frame 310 before the measurement starts, that is, at this time, the sliding block 320 and the infrared rangefinder 330 on the sliding block 320 are not above the fixing frame assembly 200, so that it is convenient to place or take the speaker shell on the fixing assembly. After the speaker shell is placed, the sliding block slides to the top of the fixing assembly, that is, the top of the speaker shell, and the infrared rangefinder 330 starts to measure the pad height of the speaker shell. After the infrared rangefinder 330 finishes the measurement, the sliding block will slide back to the initial position, so that it is convenient for the user to take the measured speaker shell.

[0023] In order to adjust the height of the infrared rangefinder 330, in one embodiment, Figure 1 As shown, a moving groove 321 is provided on the sliding block 320, a moving block 322 is slidably arranged in the moving groove 321, the sliding direction of the moving block 322 is perpendicular to the sliding direction of the sliding block 320, and the infrared rangefinder 330 is fixedly arranged on the moving block 322. Specifically, by sliding the moving block 322 in the moving groove 321, the distance between the moving block 322 and the table surface of the workbench can be adjusted, that is, the height of the infrared rangefinder 330 on the moving block 322 relative to the workbench, so that the appropriate height measurement distance can be adjusted according to different sound housings, so as to reduce the error of the infrared rangefinder 330 in measuring the distance between the infrared rangefinder 330 and the welding pad.

[0024] In order to quickly display the measurement results, in one embodiment, as Figure 1 and Figure 2As shown, the height measuring component also includes a determination indicator light 340, and the indicator light 340 is arranged on a side surface of the slider frame 310, and the indicator light 340 is electrically connected to the infrared rangefinder 330. Specifically, the indicator light 340 is used to display the detection result of the pad height measuring device 10. The indicator light 340 has two colors, red and green. When the infrared rangefinder 330 measures the distance between the pad and the pad, that is, the height of the pad is within the preset correct range value, the indicator light 340 lights up green; conversely, when the infrared rangefinder 330 measures the distance between the pad and the pad, that is, the height of the pad exceeds or is lower than the preset range value, the indicator light 340 lights up red. By setting the indicator light 340 to light up with the corresponding light color in the above manner, the measurement result can be quickly displayed.

[0025] In order to remind the user that the height of the pad exceeds or falls below the preset value, in one embodiment, the height measuring component further includes an alarm sound (blocked in the figure, not shown), which is arranged in the sliding block 320 and electrically connected to the infrared height measuring component 300.

[0026] In order to fix the speaker housing on the base 100, in one embodiment, Figure 1 As shown, the fixing frame assembly 200 includes a movable bottom plate 210, a support column 220 and a fixed mold 230; the movable bottom plate 210 is slidably arranged on the base 100, the support column 220 is detachably arranged on the movable bottom plate 210, and the fixed mold 230 is fixedly arranged on the support column 220. Specifically, the movable bottom plate 210 is used to slide on the base 100, so that the pads on the sound shell on the movable bottom plate 210 that need to measure the height can be moved to a suitable position, thereby facilitating the infrared rangefinder 330 to measure the height. The support column 220 is used to support and fix the fixed mold 230 on the movable bottom plate 210, and the support column 220 is detachably arranged on the movable bottom plate 210, so that the fixed mold 230 can be fixed by selecting a suitable support column 220 according to different fixed molds 230.
