Description

Technical Field

[0001] This utility model relates to the field of glass cover plate testing technology, and in particular to a flatness testing device for glass cover plates. Background Technology

[0002] For example, Chinese Patent No. CN212806983U discloses a flatness testing device for glass covers. Through the cooperation between the support mechanism, the longitudinal adjustment mechanism, the transverse adjustment mechanism and the testing mechanism, a flatness testing device for glass covers is realized, which can perform multi-directional testing of glass covers, thereby greatly improving the testing efficiency of glass covers.

[0003] However, the testing device in the aforementioned application performs point-to-area testing using a test probe, which is very inefficient. Furthermore, it cannot accurately mark any uneven areas on the glass cover, making it difficult to identify problems and improve subsequent production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flatness detection device for glass covers, which solves the technical problems of low detection efficiency and inability to accurately mark uneven areas in existing technologies, thereby achieving the purpose of improving detection efficiency and marking uneven areas.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a flatness testing device for a glass cover plate, comprising support rods installed on both sides of the top of a testing platform, wherein the testing platform is provided with a testing mechanism for marking uneven areas of the glass cover plate.

[0006] The testing mechanism includes an electromagnetic backplate installed on the back of the testing platform, and a gantry frame installed on the top of the support rod. An electric lifting rod is installed on the top of the gantry frame, and a pressure plate is installed at the bottom free end of the electric lifting rod through the gantry frame. The pressure plate has through holes arranged in an array, and a guardrail is installed on its outer side. A flipping assembly for testing both sides of the glass cover is provided on the support rod, and a recycling assembly for recycling the magnetorheological fluid is provided on the testing platform.

[0007] A further improvement is that the flipping assembly includes a rotating shaft rotatably connected to a rotating hole at the top of the support rod, and a U-shaped clamping plate is installed at the inner end of the rotating shaft. A flipping motor that drives the rotating shaft to rotate is installed on the left support rod, and a clamping component is provided on the U-shaped clamping plate to prevent the glass cover from slipping when flipped.

[0008] A further improvement is that the clamping assembly includes an electric push rod mounted on the top of the U-shaped clamping plate, and the bottom free end of the electric push rod passes through the U-shaped clamping plate and is mounted with a fixing plate, the bottom of which is fitted with a rubber pad.

[0009] A further improvement is that a pressure sensor is installed in the mounting groove on the fixing plate, and a corresponding slot adapted to the pressure sensor is also provided on the rubber pad.

[0010] A further improvement is that the circulation component includes a liquid storage box installed inside the testing station, and a manifold is installed on the testing station. A drain port communicating with the liquid storage box is opened through the center of the manifold. A circulation pump communicating with the liquid storage box is installed on the side of the testing station, and an infusion pipe is installed at the outlet of the circulation pump.

[0011] A further improvement is that the bottom of the manifold is a conical structure, and the top of the infusion tube passes through the gantry frame and is located above the pressure plate.

[0012] By employing the above technical solution, this utility model provides a flatness detection device for glass covers, which has at least the following beneficial effects:

[0013] 1. This utility model uses an electric lifting rod to push the pressure plate down to contact the glass cover plate. Then, magnetorheological fluid is poured onto the pressure plate. The magnetorheological fluid flows into the surface of the glass cover plate along the through hole and seeps into its uneven areas. Then, the electromagnetic back plate is energized to generate a magnetic field, which transforms the magnetorheological fluid into Bingham fluid. After the pressure plate is raised, the uneven areas of the glass cover plate can be directly observed, which facilitates subsequent targeted improvements to the production process.

[0014] 2. In this invention, when the magnetorheological fluid overflows from the glass cover, it flows into the manifold and into the storage box, thereby realizing the recovery of the magnetorheological fluid. When it is necessary to inject the magnetorheological fluid for testing, the circulation pump is started to pump the magnetorheological fluid in the storage box into the infusion tube and inject it into the pressure plate, thereby realizing the recycling of the magnetorheological fluid.

[0015] 3. This utility model uses a flipping motor to drive the rotating shaft to rotate, thereby causing the glass cover plate inside the U-shaped clamping plate to flip and perform flatness detection on its other side, thus improving the detection efficiency. In conjunction with the electric push rod to push the fixing plate down, the glass cover plate is pressed and fixed, preventing the glass cover plate from falling and breaking during the flipping process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] To address the issues of low detection efficiency and inability to accurately mark uneven areas in existing technologies, this embodiment provides a flatness detection device for glass covers. Please refer to... Figures 1-5 This embodiment provides a flatness testing device for glass covers, which can improve testing efficiency and mark uneven areas. The device includes support rods 2 installed on both sides of the top of a testing platform 1. A testing mechanism 3 is provided on the testing platform 1 to mark uneven areas of the glass cover. The testing mechanism 3 detects the flatness of both sides of the glass cover and marks uneven areas, facilitating visual observation of defects and enabling subsequent production improvements.

[0031] Because existing technologies are inefficient and cannot accurately mark uneven areas, this device includes a detection mechanism 3. The detection mechanism 3 includes an electromagnetic backplate 31 mounted on the back of the detection table 1, a gantry frame 32 mounted on the top of the support rod 2, an electric lifting rod 33 mounted on the top of the gantry frame 32, and a pressure plate 34 mounted on the bottom free end of the electric lifting rod 33, which passes through the gantry frame 32. The pressure plate 34 has through holes arranged in an array, and a guardrail 35 is mounted on its outer side. A flipping assembly 36 for detecting both sides of the glass cover is mounted on the support rod 2. The testing platform 1 is equipped with a recycling component 37 for recovering and reusing the magnetorheological fluid. The glass cover is placed on the testing platform 1, and then the electric lifting rod 33 is activated to push the pressure plate 34 down to contact the glass cover. The magnetorheological fluid is then poured onto the pressure plate 34. The magnetorheological fluid flows into the surface of the glass cover along the through hole and seeps into its uneven areas. Then, the electromagnetic back plate 31 is energized to generate a magnetic field, which converts the magnetorheological fluid into Bingham fluid. The pressure plate 34 is then raised, and the uneven areas of the glass cover can be directly observed, which facilitates subsequent targeted improvements to the production process.

[0032] To further improve the inspection efficiency of the glass cover, the device is also equipped with a flipping assembly 36. The flipping assembly 36 includes a rotating shaft 361 rotatably connected to a rotating hole at the top of the support rod 2. U-shaped clamping plates 362 are installed at the inner ends of the rotating shaft 361. A flipping motor 363 that drives the rotating shaft 361 to rotate is installed on the left support rod 2. The U-shaped clamping plates 362 are equipped with clamping components 364 to prevent the glass cover from slipping when flipped. The two ends of the glass cover are inserted into the U-shaped clamping plates 362 respectively. Then, the flipping motor 363 is started to drive the rotating shaft 361 to rotate, thereby causing the glass cover inside the U-shaped clamping plates 362 to flip and perform flatness inspection on the other side, thus improving the inspection efficiency.

[0033] To prevent the glass cover from slipping and breaking during the flipping process, the device is also equipped with a clamping assembly 364. The clamping assembly 364 includes an electric push rod 3641 installed on the top of the U-shaped clamping plate 362. The bottom free end of the electric push rod 3641 passes through the U-shaped clamping plate 362 and is fitted with a fixing plate 3642. A rubber pad 3643 is installed at the bottom of the fixing plate 3642. When the glass cover is inserted into the U-shaped clamping plate 362, the electric push rod 3641 is activated to push the fixing plate 3642 down until it contacts the glass cover and presses it in place, thereby preventing the glass cover from falling during the flipping process. The rubber pad 3643 also increases friction and provides a certain cushioning and protective effect.

[0034] To prevent the glass cover from being crushed due to excessive downward pressure from the electric push rod 3641, a pressure sensor 3644 is installed in the mounting groove on the fixed plate 3642. A corresponding slot for the pressure sensor 3644 is also provided on the rubber pad 3643. When the fixed plate 3642 moves down and contacts the glass cover, the pressure sensor 3644 is subjected to force and emits an electrical signal, thereby stopping the electric push rod 3641 from moving down and preventing excessive downward movement that could cause the glass cover to break.

[0035] Example 2

[0036] To avoid wasting the overflowing magnetorheological fluid, therefore, based on Example 1, as follows: Figures 1-5 As shown, the device is also equipped with a circulation component 37, which includes a liquid storage box 371 installed in the test platform 1, and a manifold 372 installed on the test platform 1. A drain port 373 communicating with the liquid storage box 371 is opened through the center of the manifold 372. A circulation pump 374 communicating with the liquid storage box 371 is installed on the side of the test platform 1, and an infusion pipe 375 is installed at the outlet of the circulation pump 374.

[0037] The bottom of the manifold 372 has a conical structure, and the top of the infusion tube 375 passes through the gantry frame 32 and is located above the pressure plate 34. When the magnetorheological fluid overflows from the glass cover, it flows into the manifold 372 and into the storage box 371 through the drain port 373, thereby realizing the recovery of the magnetorheological fluid. When it is necessary to inject the magnetorheological fluid for testing, the circulation pump 374 is started to pump the magnetorheological fluid in the storage box 371 into the infusion tube 375 and inject it onto the pressure plate 34, thereby realizing the recycling of the magnetorheological fluid.
