Description

Technical Field

[0001] This utility model relates to the technical field of glass cover plate testing equipment, and in particular to a glass cover plate thickness testing device. Background Technology

[0002] During the processing of glass cover plates, after the initial shape is formed, a grinding mill (or pulverizer) is used to further polish it according to requirements. After the polishing is completed, the thickness of the glass cover plate is checked by a thickness gauge to ensure the initial processing quality of the glass cover plate.

[0003] In existing technologies, operators often have a significant amount of abrasive powder adhering to their hands. When using handheld thickness gauges for testing, this powder can easily affect the gauge's accuracy and lifespan (for example, powder entering the gauge's interior can cause it to jam and break), thus impacting the quality of the test. Furthermore, handheld thickness gauges have a market value of around 2500 yuan, resulting in relatively high testing costs. Damage to these gauges further increases the company's testing expenses. Thirdly, handheld thickness gauges typically only measure depths up to 30mm (with special procurement allowing for a maximum depth of 120mm), making it difficult to comprehensively measure large glass covers (thickness exceeding 120mm).

[0020] refer to Figures 1 to 3This application provides a glass cover thickness detection device, including a product carrier 10, an adjusting bracket 20, and a digital displacement sensor 30. The product carrier 10 is used to place the glass cover to be tested. The adjusting bracket 20 includes a vertical support rod 21 and a horizontal adjusting rod 22. The vertical support rod 21 can be fixed to the ground or a workbench, or to other equipment, such as the support frame 41 described later. The horizontal adjusting rod 22 extends horizontally and is vertically connected to the vertical support rod 21 at one end in a manner that allows for adjustment of height and horizontal position. The digital displacement sensor 30 extends vertically. The digital displacement sensor 30 is vertically connected to the opposite end of the horizontal adjustment rod 22, and is positioned directly above the product carrier 10 to detect the thickness of the glass cover plate to be tested on the product carrier 10. In this way, the thickness of the glass cover plate to be tested on the product carrier 10 can be detected by flexibly adjusting the height and horizontal position of the digital displacement sensor 30. The detection is convenient, and the height position can be adjusted to detect glass cover plates of different thicknesses. The detection range is wide, and the detection cost can be effectively reduced. It is also not easily affected by grinding powder, which reduces the detection accuracy. It is also not easily damaged by grinding powder, resulting in a longer service life.

[0021] In one embodiment, the digital display displacement sensor 30 is a pneumatic digital display contact displacement sensor, and the digital display displacement sensor 30 is connected to the air source 33 in sequence through the solenoid valve 31 and the pressure reducing valve 32. The solenoid valve 31 is connected to the power distribution cabinet 34.

[0022] In one embodiment, the end of the lateral adjusting rod 22 near the vertical support rod 21 is sleeved on the vertical support rod 21, and a first linear notch 201 is provided vertically in the middle position. Simultaneously, a first fastening screw 221 is installed on the lateral adjusting rod 22 to penetrate vertically through the first linear notch 201, so that after the lateral adjusting rod 22 is moved vertically into position and / or rotated horizontally into position, it is fixed to the vertical support rod 21. In specific operation, firstly, the first fastening screw 221 is tightened to loosen the first linear notch 201. At this time, the lateral adjusting rod 22 can be moved vertically, or rotated horizontally with the vertical support rod 21 as the rotation axis, or simultaneously moved vertically and rotated horizontally, to adjust the height and horizontal position of the digital displacement sensor 30 through the lateral adjusting rod 22. After adjustment, the first fastening screw 221 is tightened in the opposite direction to tighten the first linear notch 201, firmly fixing the lateral adjusting rod 22 to the vertical support rod 21. The overall structure is simple and easy to operate.

[0023] In one embodiment, the other end of the horizontal adjusting rod 22 has a clamping channel 202 extending vertically, and a second linear notch 203 extending vertically through the clamping channel 202 is provided at the middle position. The digital displacement sensor 30 is installed within the clamping channel 202. A second fastening screw 222 is also installed on the horizontal adjusting rod 22 to vertically penetrate the second linear notch 203, thereby fixing the digital displacement sensor 30 to the horizontal adjusting rod 22 after it has moved vertically into position. In specific operation, first, the second fastening screw 222 is tightened to loosen the second linear notch 203. At this time, the digital displacement sensor 30 can be adjusted vertically within the clamping channel 202. After adjustment, the second fastening screw 222 is tightened in the opposite direction to firmly fix the digital displacement sensor 30 to the horizontal adjusting rod 22. This allows for flexible adjustment of the height position of the digital displacement sensor 30. It can also be used in conjunction with the aforementioned first fastening screw 221 to further increase the height adjustment stroke of the digital displacement sensor 30, thereby further increasing the thickness detection range.

[0024] In some cases, the glass cover plate to be tested can be cleaned first, and then placed on the product carrier 10 for testing. Alternatively, cleaning and testing can be integrated to improve testing efficiency. Therefore, in one embodiment, the glass cover plate thickness testing device further includes a wastewater tank 40 and a cleaning mechanism 50. The wastewater tank 40 is equipped with a support frame 41, and the product carrier 10 is fixedly mounted on the top of the support frame 41. The lower part of the vertical support rod 21 is fixedly connected to the support frame 41. The cleaning mechanism 50 includes a universal nozzle 51, a nozzle bracket, and a water supply pipe 52. The universal nozzle 51 is mounted on the nozzle bracket and faces the product carrier 10 to clean the glass cover plate to be tested on the product carrier 10. The universal nozzle 51 is connected to a water source 53 through the water supply pipe 52. A water pump 521 and a filter 522 are sequentially installed on the 52 unit. The filter 522 is located near the water source 53. The water pump 521 is controllably connected to the power distribution cabinet 34. The power distribution cabinet controls the start and stop timing of the water pump 521. For example, after the glass cover to be tested is placed in place and the digital displacement sensor 30 moves into position, the water pump 521 is started first. The water is sprayed onto the surface of the glass cover through the universal nozzle 51. The water pressure and flow rate can be adjusted by the frequency converter inside the water pump 521 to ensure the surface of the glass cover is clean and to reduce the movement and scratches of the glass cover, ensuring that the test is not affected. The water pump automatically stops after 5 seconds (this can be achieved by using a time relay in the prior art). Then, the power distribution cabinet controls the start of the solenoid valve 31 to control the digital displacement sensor 30 to detect the thickness of the glass cover. The thickness data can be displayed on the power distribution cabinet or on the built-in display screen.

[0025] In one embodiment, the top of the product carrier 10 is provided with a plurality of columnar protrusions 11 of the same height at intervals. The plurality of columnar protrusions 11 include a main protrusion 111 located at the center and a plurality of secondary protrusions 112 arranged outside the main protrusion 111. The diameter of the main protrusion 111 is larger than the diameter of the secondary protrusions 112. For example, the diameter of the main protrusion 111 is 15mm and the diameter of the secondary protrusions 112 is 5mm. Thus, the columnar protrusions 11 can support the glass cover plate to a certain height, ensuring the accuracy of the thickness detection data. At the same time, cleaning wastewater is less likely to contaminate the glass cover plate. In addition, the main protrusion 111 with a larger diameter can also play a role in positioning the product, so that the glass cover plate can be quickly and accurately placed in the middle position of the product carrier 10.

[0026] In one embodiment, a drain pipe 42 is connected to the bottom of the sewage tank 40, and a drain valve is installed on the drain pipe 42 for discharging sewage from the sewage tank 40.
