Description

Technical Field

[0001] The present invention relates to the technical field of electronic screen thickness measurement, and in particular to an electronic screen thickness measurement device. Background Art

[0002] In the prior art, in the production and manufacturing process of the 3C industry, it is usually necessary to conduct quality inspection on various electronic screens after manufacturing, and the quality inspection of electronic screens mainly includes various measurement operations such as color, glossiness, thickness, scanning and size. Among them, because different inspection methods require the use of different measuring equipment, multiple measuring equipment is required in the multiple inspection processes of various electronic screens in the prior art. In order to save the time of transporting the inspected electronic screens between multiple measuring equipment, the prior art will set a device for driving the electronic screen to move between multiple measuring equipment.

[0003] In the measurement equipment for color, glossiness and other electronic screens that use light detection, due to the integrity of the electronic screen material, there is no need to specifically perform targeted measurement operations on a certain area of the electronic screen. However, when detecting the size and thickness of the electronic screen, due to certain differences in the appearance of electronic screens in the prior art, it is necessary to ensure that the overall thickness and size of the electronic screen remain uniform. In the prior art, the utility model with patent announcement number CN218884889U has a classification number of G01B, and the thickness detection device includes: a test bench, provided with a bearing surface for placing a screen; a carrying mechanism for transporting the screen to be tested to the test bench, and for transporting the tested screen from the test bench; an OCT detection mechanism, arranged on the side of the test bench away from the bearing surface, for scanning the screen on the test bench to obtain thickness information of each layer structure of the screen; this document can improve the detection efficiency of the screen and ensure the accuracy of the detection. Another patent publication number is CN112461080A, which discloses a thickness detection device for the production of mobile phone screen display panels. Its classification number is G01B, which relates to the field of mobile phone display module production technology. The thickness detection device for the production of mobile phone screen display panels includes a device body, a detection slot is opened on the left side of the device body, and a triangular block is arranged on the top of the detection slot. The left side of the triangular block is rotatably installed inside the device body, and the top of the right side of the triangular block is in contact with the first movable plate, and the top of the first movable plate is fixedly connected to the second movable plate. In the thickness detection device for the production of mobile phone screen display panels, when the mobile phone screen is placed in the detection slot and moved to the right, if the thickness of the mobile phone screen is qualified, the qualified prompt plate will completely extend out of the device body. If the mobile phone screen is unqualified, the mobile phone screen cannot be completely moved into the detection slot, and the qualified prompt plate will not extend, thereby reducing the use cost without affecting the measurement accuracy of the mobile phone screen thickness.

[0004] However, the existing technology has defects in measuring the thickness of electronic screens: it is difficult to ensure the position between the electronic screen and the thickness measuring device, which makes the measured value inaccurate; therefore, during the transportation process of the electronic screen, it is necessary to ensure that the position between the electronic screen and the thickness measuring device is accurate enough to facilitate the thickness measuring device to accurately measure the electronic screen.

Specific implementation manner

[0032] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0033] As Figures 1 to 8 shown, this embodiment proposes an electronic screen thickness measurement device, which is applied to the detection platform 1. Along the center point of the polygonal turntable 2 on the detection platform 1, a color measurement device 24, a glossiness measurement device 25, and a thickness measurement device 26 are sequentially arranged. Between the color measurement device 24, the glossiness measurement device 25, and the thickness measurement device 26 and the detection platform 1, there is a three-axis moving mechanism 27, which is used to drive the working ends of the color measurement device 24, the glossiness measurement device 25, and the thickness measurement device 26 to move in the X-axis, Y-axis, and Z-axis. Among them, in order to avoid the influence of external light on the measurement accuracy of the glossiness measurement device 25 during the measurement of the electronic screen by the glossiness measurement device 25, light-shielding plates are arranged on both sides of the glossiness measurement device 25;

[0034] It includes a polygonal turntable 2. The polygonal turntable 2 is rotationally connected to the detection platform 1 through a rotating mounting component. The rotating mounting component includes a rotating mounting seat 5 and a main shaft drive motor 6. The rotating mounting seat 5 is arranged inside the detection platform 1. The polygonal turntable 2 is rotationally connected to the rotating mounting seat 5 through a rotating seat. The main shaft drive motor 6 is arranged on the rotating mounting seat 5. The output end of the main shaft drive motor 6 is connected to the polygonal turntable 2. When it is necessary to drive the polygonal turntable 2 to rotate so that each positioning tray 3 for placing the electronic screen corresponds to each measurement device in turn, start the main shaft drive motor 6 to drive the rotating seat and the polygonal turntable 2 to rotate along the center point of the rotating mounting seat 5;

[0035] It further includes a positioning tray 3. A plurality of mounting grooves are circumferentially formed on the polygonal turntable 2, and a positioning tray 3 is fixedly connected in each mounting groove. Two suction clamps 4 are arranged on both sides of each positioning tray 3. The two suction clamps 4 on the same side and one side of the positioning tray 3 are set as a corresponding sliding assembly. The corresponding sliding assembly includes a sliding track 7 and a sliding seat 8. Accommodating grooves are formed on both sides of the positioning tray 3, and two sliding tracks 7 are fixedly connected in the accommodating grooves. The two sliding tracks 7 are fixedly connected in the accommodating groove in a shape of an inverted V. A sliding seat 8 is slidably arranged in the sliding track 7. The suction clamp 4 is arranged through the sliding seat 8. Rotating balls 9 are ball-jointed on both sides of the sliding seat 8, and the rotating balls 9 are in contact with the inner wall of the sliding track 7. In order to make the position of the suction clamp 4 correspond to the volume of the electronic screen to be detected, the two sliding seats 8 on the same side slide in their respective sliding tracks 7, so as to adjust the position of the suction clamp 4. And because the two sliding tracks 7 correspond to each other, the movement of the two sliding seats 8 is kept corresponding.

[0036] An air injection and sealing assembly is arranged between the two suction clamps 4 on the same side. The air injection and sealing assembly includes a communicating air pipe 10 and an exhaust pipe 11. The bottoms of the two suction clamps 4 are communicated with the communicating air pipe 10. The middle of the communicating air pipe 10 is communicated with the exhaust pipe 11. A solenoid valve is arranged on the exhaust pipe 11. After the electronic screen is in close contact with the top of the suction clamp 4, the gas between the suction clamp 4 and the electronic screen is discharged through the exhaust pipe 11 and the communicating air pipe 10, so that the suction clamp 4 performs a vacuum adsorption operation on the electronic screen, and the electronic screen is fixed on the positioning tray 3. The suction clamp 4 is a prior art device commonly used for adsorbing and clamping smooth parts in the prior art, and is a prior art device well known to those skilled in the art.

[0037] On one side of the rotating mounting assembly, a calibration assembly is provided. The calibration assembly is used to adjust the position of the suction fixture 4 on the positioning tray 3. The calibration assembly includes a moving chute 12 and a first electric cylinder 14. The number of moving chutes 12 is set to two. The moving chutes 12 are located within the detection platform 1. Two calibration blocks 13 are slidably arranged oppositely within the moving chutes 12. An electromagnetic connecting member is provided between the calibration blocks 13 and the sliding seat 8. The electromagnetic connecting member includes an electromagnet 15. Electromagnets 15 are provided on both calibration blocks 13. A ferromagnetic strip 16 is provided on the sliding seat 8. The electromagnet 15 is magnetically connected to the ferromagnetic strip 16. Two first electric cylinders 14 are provided within the detection platform 1. The output end of the first electric cylinder 14 is fixedly connected to the moving chute 12. When it is necessary to adjust the position of the suction fixture 4, start the first electric cylinder 14 to push the moving chute 12 and the calibration block 13 towards the sliding seat 8, so that the electromagnet 15 is in contact with the ferromagnetic strip 16. Then, supply power to the electromagnet 15 to generate magnetism, so that a magnetic connection is maintained between the calibration block 13 and the sliding seat 8. When the first electric cylinder 14 pushes the moving chute 12 to move, the calibration block 13 can drive the sliding seat 8 and the suction fixture 4 to move within the sliding track 7;

[0038] A bidirectional screw 17 is rotatably connected within the moving chute 12. The calibration block 13 is threadedly connected to the bidirectional screw 17. A screw driving motor 18 is provided on the moving chute 12. The output end of the screw driving motor 18 is fixedly connected to the bidirectional screw 17. Because as the sliding seat 8 moves within the sliding track 7, the two sliding seats 8 on the same side will also approach each other. At this time, start the screw driving motor 18 to drive the bidirectional screw 17 to rotate, so that the calibration block 13 adjusts according to the moving path of the sliding seat 8. And because the calibration block 13 needs to adjust the suction fixtures 4 at different positions among multiple positioning trays 3, the bidirectional screw 17 can also be used to adjust the lateral position of the calibration block 13.

[0039] An air suction cooperation mechanism is further included. An air suction cooperation mechanism is provided on one side of the rotating mounting assembly. The air suction cooperation mechanism cooperates with the two gas injection and sealing assemblies. The air suction cooperation mechanism includes a support plate body 19 and a moving assembly. The support plate body 19 is fixedly connected to the rotating mounting seat 5. A vacuum pump 20 is provided on the support plate body 19. An air suction assembly is provided at the air suction end of the vacuum pump 20. The air suction assembly includes sealing insertion cylinders 21. The number of sealing insertion cylinders 21 corresponds one by one. The sealing insertion cylinders 21 are all communicated with the air suction end of the vacuum pump 20. The sealing insertion cylinders 21 cooperate with the inner wall of the exhaust pipe 11. Move one of the positioning trays 3 directly above the support plate body 19, and then place the electronic screen between the multiple suction fixtures 4, so that the sealing insertion cylinders 21 are inserted into the corresponding exhaust pipes 11. Then use the vacuum pump 20 to extract the gas between the suction fixtures 4 and the electronic screen, so that the suction fixtures 4 vacuum adsorb the electronic screen;

[0040] A moving component for driving the suction component to move is arranged on the support plate body 19. The moving component includes a second electric cylinder 22. The second electric cylinder 22 is fixedly connected to the support plate body 19. A connecting plate 23 is fixedly connected between the two sealing insertion cylinders 21. The output end of the second electric cylinder 22 is fixedly connected to the connecting plate 23. When it is necessary to move the position of the sealing insertion cylinder 21, the second electric cylinder 22 is started to drive the connecting plate 23 to rise, so that the sealing insertion cylinder 21 enters the corresponding exhaust pipe 11.

[0041] The working principle of the automatic positioning mechanism for thickness measurement:

[0042] Move one of the positioning trays 3 directly above the support plate body 19. Start the first electric cylinder 14 to push the moving chute 12 and the calibration block 13 towards the sliding seat 8, so that the electromagnet 15 is in contact with the ferromagnetic strip 16. Then, supply power to the electromagnet 15 to make it generate magnetism, so that a magnetic connection is maintained between the calibration block 13 and the sliding seat 8. When the first electric cylinder 14 pushes the moving chute 12 to move, the calibration block 13 can drive the sliding seat 8 and the suction fixture 4 to move within the sliding track 7. Start the screw drive motor 18 to drive the bidirectional screw 17 to rotate, so that the calibration block 13 adjusts in cooperation with the moving path of the sliding seat 8, so that the position of the suction fixture 4 within the positioning tray 3 corresponds to the volume of the electronic screen.

[0043] Then, place the electronic screen between the multiple suction fixtures 4. Start the second electric cylinder 22 to drive the connecting plate 23 to rise, so that the sealing insertion cylinder 21 enters the corresponding exhaust pipe 11. Use the vacuum pump 20 to extract the gas between the suction fixture 4 and the electronic screen, so that the suction fixture 4 vacuums and adsorbs the electronic screen. Then, start the main shaft drive motor 6 to drive the rotating seat and the polygonal turntable 2 to rotate around the center point of the rotating mounting seat 5, so that the electronic screen is measured among the multiple measuring devices.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
