Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing device for cracks on the surface of glass panels. Background Technology

[0002] Microcracks that occur during the processing and use of glass panels are unavoidable defects that can significantly weaken the overall strength of the glass panel and thus greatly affect its performance. Therefore, timely and effective testing is necessary to determine the extent of damage to the panel.

[0003] In the existing technology, the commonly used equipment for detecting fine cracks on glass panels is microwave testing equipment. The core principle of microwave testing for cracks on glass surfaces is based on the interaction between microwaves and the dielectric properties and structural defects of materials. When microwave frequencies, typically 1-100 GHz, encounter the surface of a glass panel, their propagation characteristics will change due to internal cracks in the material. Cracks will cause local changes in the dielectric constant, which in turn will cause abnormalities in the phase, amplitude, or frequency response of the microwave signal.

[0004] However, existing microwave testing equipment has the following problems: it does not have the function of positioning glass panels, and it requires additional support equipment to fix and support the glass panels. Furthermore, it requires staff to manually adjust glass panels of different sizes to a suitable position with the microwave testing equipment body, which is very troublesome. Therefore, a device for detecting cracks on the surface of glass panels is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] like Figure 1-2 As shown, this utility model embodiment provides a detection device for cracks on the surface of a glass panel, including a support platform 2 and a microwave detection device body 1. The support platform 2 is installed on the upper end of the base assembly 3, and the microwave detection device body 1 is installed on the upper end of the support platform 2.

[0050] The base assembly 3 includes a support cylinder 311, a base 301, a fixed side cylinder 305, an L-shaped connecting cylinder 306, a support column 309, a support plate 308, and a clamping plate 307. The support cylinder 311 is fixed to the lower end of the support platform 2, the base 301 is fixed to the lower end of the support cylinder 311, the fixed side cylinder 305 is installed at the right end of the support cylinder 311, the L-shaped connecting cylinder 306 is installed at the other end of the fixed side cylinder 305, the support column 309 is installed at the upper end of the L-shaped connecting cylinder 306, the support plate 308 is installed at the upper end of the support column 309, and there are two clamping plates 307, which are symmetrically arranged on the front and rear sides of the support plate 308.

[0051] The microwave detection device body 1 can detect cracks on the surface of a glass panel mounted on a support plate 308 using microwaves. The microwave detection device body 1 is existing technology and is commonly used for detecting glass cracks. When microwave frequencies, typically 1-100GHz, encounter the surface of a glass panel, their propagation characteristics will change due to internal cracks in the material. Cracks can cause changes in the local dielectric constant, which in turn can cause abnormalities in the phase, amplitude, or frequency response of the microwave signal.

[0052] In this embodiment, as Figure 2-3 As shown, the base assembly 3 also includes a lower annular mounting sleeve 313 and an upper annular mounting sleeve 312. The lower annular mounting sleeve 313 is rotatably mounted on the support cylinder 311 via a bearing, and the upper annular mounting sleeve 312 is rotatably mounted on the support cylinder 311 via a bearing. The upper annular mounting sleeve 312 is located above the lower annular mounting sleeve 313, and the lower annular mounting sleeve 313 is fixedly connected to the upper annular mounting sleeve 312 via multiple vertically arranged fixed connecting rods 302.

[0053] The base assembly 3 also includes a first motor 303, a first gear 304, and a second gear 314. The first motor 303 is fixedly installed inside the bottom of the base 301. The upper end of the output shaft of the first motor 303 passes through the base 301 and extends to the top of the base 301. The first gear 304 is fixedly fitted on the output shaft of the first motor 303 and is located above the base 301. The second gear 314 is fixedly fitted on the lower annular mounting sleeve 313, and the first gear 304 and the second gear 314 mesh with each other.

[0054] By starting the first motor 303, the first motor 303 can drive the lower annular mounting sleeve 313 to rotate through the first gear 304 and the second gear 314, thereby driving the upper annular mounting sleeve 312 to rotate. This enables automatic adjustment of the angle of the glass panel mounted on the support plate 308, allowing glass panels of different sizes to be adjusted to a suitable angle according to the position of the microwave detection equipment body 1, thereby improving the detection effect.

[0055] The base assembly 3 also includes a first electric push rod 315, which is fixedly installed inside the left end of the fixed side cylinder 305. The fixed side cylinder 305 is fixedly installed on the right end of the upper annular mounting sleeve 312. The right end of the output end of the first electric push rod 315 is fixedly connected to the bottom left end of the L-shaped connecting cylinder 306. The bottom of the L-shaped connecting cylinder 306 slides horizontally through the right end of the fixed side cylinder 305.

[0056] By activating the first electric push rod 315, the distance between the L-shaped connecting cylinder 306 and the support cylinder 311 can be adjusted, thereby facilitating the automatic adjustment of the distance between the glass panel on the support plate 308 and the microwave detection equipment body 1. This allows the distance between the microwave detection equipment body 1 and glass panels of different sizes to be adjusted to a more suitable range, thus improving the detection effect.

[0057] The base assembly 3 also includes a second electric push rod 316, which is fixedly installed inside the bottom of the L-shaped connecting cylinder 306. The upper end of the output end of the second electric push rod 316 is fixedly connected to the lower end of the support column 309, and the support column 309 slides through the upper end of the L-shaped connecting cylinder 306 in the vertical direction.

[0058] By activating the second electric push rod 316, the height of the support column 309 can be automatically adjusted, thereby adjusting the height of the glass panel on the support plate 308. This allows glass panels of different sizes to be adjusted to a suitable height according to the position of the microwave detection equipment body 1, thereby improving the detection effect.

[0059] The base assembly 3 also includes a second motor 317, which is embedded and fixedly installed on the upper end of the support column 309. The upper end of the output shaft of the second motor 317 passes through the upper end of the support column 309 and is fixedly connected to the lower middle position of the support plate 308.

[0060] By starting the second motor 317, the second motor 317 can drive the support plate 308 to rotate, thereby adjusting the angle of the glass panel on the support plate 308. This allows glass panels of different sizes to be adjusted to a suitable angle according to the position of the microwave detection equipment body 1, thereby improving the detection effect.

[0061] like Figure 4As shown, the base assembly 3 also includes a dual-axis motor 319, a first lead screw 318, a second lead screw 320, and rectangular nut blocks 321. The dual-axis motor 319 is fixedly installed inside the support plate 308. The first lead screw 318 and the second lead screw 320 are both arranged in the front-to-back direction. The ends of the first lead screw 318 and the second lead screw 320 are respectively fixedly connected to the output ends of the front and rear ends of the dual-axis motor 319. The threads of the first lead screw 318 and the second lead screw 320 have opposite directions and the same thread density. There are two rectangular nut blocks 321. Nut blocks 321 are threaded onto the first lead screw 318 and the second lead screw 320 respectively. Two rectangular nut blocks 321 are symmetrically fixed at one end away from each other, and two extension rods 310 are arranged in the front-back direction. The other end of the extension rods 310 passes through the support plate 308. The other end of the two extension rods 310 located in front of the dual-axis motor 319 is fixedly connected to the clamping plate 307 located in front of the dual-axis motor 319. The other end of the two extension rods 310 located behind the dual-axis motor 319 is fixedly connected to the clamping plate 307 located behind the dual-axis motor 319.

[0062] The glass panel can be placed on the support plate 308, and then the dual-axis motor 319 can be started. The dual-axis motor 319 drives the first lead screw 318 and the second lead screw 320 to rotate, which in turn drives the rectangular nut block 321 on it to move. The two rectangular nut blocks 321 moving in opposite directions can drive the clamping plate 307 through the extension rod 310 on them. The two clamping plates 307 moving in opposite directions can clamp and fix the glass panel, thereby achieving the positioning of the glass panel.

[0063] The lower end of the rectangular nut block 321 slides and fits against the inner bottom end of the support plate 308 in the front-back direction, thereby preventing the rectangular nut block 321 from rotating axially as the first lead screw 318 and the second lead screw 320 rotate.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
