Description

Technical Field

[0001] This invention relates to the field of electronic screen thickness measurement technology, and more specifically, to an electronic screen thickness measurement device. Background Technology

[0002] In the current manufacturing process of the 3C industry, it is usually necessary to conduct quality inspections on various electronic screens after manufacturing. The quality inspection of electronic screens mainly includes measurement operations on multiple aspects such as color, gloss, thickness, scanning, and size. Since different inspection methods require the use of different measuring equipment, multiple measuring devices are needed in the current technology for the multiple inspection processes of various electronic screens. In order to save the time of transferring the electronic screens to be inspected between multiple measuring devices, the current technology will set up a device to move the electronic screens between the multiple measuring devices.

[0003] While measurement devices that use light to detect various aspects of electronic screens, such as color and gloss, do not require specific measurements of a particular area due to the uniformity of the screen material, they are suitable for measuring the size and thickness of electronic screens. However, when measuring the size and thickness of electronic screens, the varying shapes of existing screens necessitate ensuring uniformity in overall thickness and size. In the prior art, a utility model patent with publication number CN218884889U and classification number G01B describes a thickness detection device comprising: a test platform with a support surface for placing the screen; a transport mechanism for transporting the screen to be tested to the test platform and for removing the screen after testing; and an OCT detection mechanism located on the side of the test platform away from the support surface for scanning the screen to obtain thickness information of each layer of the screen structure. This document improves the efficiency and accuracy of screen detection. Another patent, CN112461080A, discloses a thickness detection device for mobile phone screen display panel production, classified under G01B, relating to the field of mobile phone display module production technology. This device includes a main body with a detection groove on its left side. A triangular block is inserted through the top of the detection groove, rotating on its left side inside the main body. The top right side of the triangular block is attached to a first movable plate, which is fixedly connected to a second movable plate. In this device, when a mobile phone screen is placed in the detection groove and moved to the right, if the screen thickness is acceptable, a qualified indicator plate will fully extend from the main body. If the screen thickness is unacceptable, it cannot move completely into the detection groove, and the qualified indicator plate will not extend. This reduces usage costs without affecting the accuracy of the screen thickness measurement.

[0004] However, existing technologies for measuring the thickness of electronic screens have shortcomings: it is difficult to guarantee the position between the electronic screen and the thickness measuring device, which makes the measurement values ​​inaccurate. Therefore, during the transportation of electronic screens, it is necessary to ensure that the position between the electronic screen and the thickness measuring device is accurate enough so that the thickness measuring device can accurately measure the electronic screen. Summary of the Invention

The rotating mounting base is disposed inside the detection platform, the polygonal turntable is rotatably connected to the rotating mounting base via a rotating base, and the spindle drive motor is disposed on the rotating mounting base. The output end of the spindle drive motor is connected to the polygonal turntable.

[0011] To further adjust the position of the suction clamp, the corresponding sliding component includes a sliding rail and a sliding seat. Receiving grooves are provided on both sides of the positioning tray. Two sliding rails are fixedly connected within the receiving grooves, forming a figure-eight shape. The sliding seat is slidably disposed within the sliding rails. The suction clamp passes through the sliding seat. Rotating balls are connected to both sides of the sliding seat via ball joints, and the rotating balls contact the inner wall of the sliding rails.

[0012] To enable the suction clamps to perform clamping operations, the air injection sealing assembly further includes a connecting air pipe and an exhaust pipe. The connecting air pipe connects the bottoms of the two suction clamps, and the exhaust pipe connects to the middle of the connecting air pipe. A solenoid valve is installed on the exhaust pipe.

[0013] To adjust the position of the suction clamp, the calibration assembly further includes a movable slide and a first electric cylinder. The number of movable slides is set to two. The movable slides are located inside the detection platform. Two calibration blocks are slidably arranged opposite each other inside the movable slides. An electromagnetic connector is provided between the calibration blocks and the sliding seat. Two first electric cylinders are provided inside the detection platform. The output end of the first electric cylinder is fixedly connected to the movable slide.

[0014] To further connect the calibration blocks and the sliding seat, the electromagnetic connector includes an electromagnet, with the electromagnet provided on both calibration blocks and an iron strip provided on the sliding seat. The electromagnet is magnetically connected to the iron strip.

[0015] To ensure that the positions of the calibration block and the sliding seat correspond, a bidirectional screw is rotatably connected inside the movable slide groove, the calibration block is threadedly connected to the bidirectional screw, and a screw drive motor is provided on the movable slide groove, with the output end of the screw drive motor fixedly connected to the bidirectional screw.

[0016] To enable the corresponding suction clamp to hold the electronic screen, a suction engagement mechanism is further included. The suction engagement mechanism is provided on one side of the rotating mounting assembly. The suction engagement mechanism engages with the two gas injection sealing assemblies. The suction engagement mechanism includes a support plate and a moving assembly. The support plate is fixedly connected to the rotating mounting base. A vacuum pump is provided on the support plate. A suction assembly is provided at the suction end of the vacuum pump. The moving assembly is provided on the support plate to drive the suction assembly to move.

[0020] 1.

During the subsequent rotation of the polygonal turntable, the electronic screen is moved between multiple measuring devices. Especially when measuring the thickness of the electronic screen, the positioning accuracy of the electronic screen can be guaranteed.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, this embodiment proposes an electronic screen thickness measuring device, applied to a detection platform 1. Along the center point of the polygonal turntable 2 on the detection platform 1, a color measuring device 24, a gloss measuring device 25, and a thickness measuring device 26 are sequentially arranged. A three-axis moving mechanism 27 is provided between the color measuring device 24, the gloss measuring device 25, and the thickness measuring device 26 and the detection platform 1, which is used to drive the working ends of the color measuring device 24, the gloss measuring device 25, and the thickness measuring device 26 to move along the X-axis, Y-axis, and Z-axis. In order to avoid the external light affecting the measurement accuracy of the gloss measuring device 25 during the measurement of the electronic screen, light shields are provided on both sides of the gloss measuring device 25.

[0034] The system includes a polygonal turntable 2, which is rotatably connected to the detection platform 1 via a rotating mounting assembly. The rotating mounting assembly includes a rotating mounting base 5 and a spindle drive motor 6. The rotating mounting base 5 is located inside the detection platform 1, and the polygonal turntable 2 is rotatably connected to the rotating mounting base 5 via the turntable. The spindle drive motor 6 is located on the rotating mounting base 5, and the output end of the spindle 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 holding an electronic screen corresponds to each measuring device in sequence, the spindle drive motor 6 is started to drive the turntable and the polygonal turntable 2 to rotate along the center point of the rotating mounting base 5.

[0035] It also includes a positioning tray 3. The polygonal turntable 2 has multiple mounting slots around its circumference. Each mounting slot is fixedly connected to a positioning tray 3. Two suction clamps 4 are provided on both sides of each positioning tray 3. The two suction clamps 4 on the same side are set as corresponding sliding components on one side of the positioning tray 3. The corresponding sliding components include sliding rails 7 and sliding seats 8. Both sides of the positioning tray 3 have receiving slots. Two sliding rails 7 are fixedly connected in the receiving slots. The two sliding rails 7 are fixedly connected in a figure-eight shape in the receiving slots. The sliding seats 8 are slidably arranged in the sliding rails 7. The suction clamps 4 are through the sliding seats 8. The two sides of the sliding seats 8 are ball-jointed to rotating balls 9. The rotating balls 9 are in contact with the inner wall of the sliding rails 7. In order to make the position of the suction clamps 4 correspond to the volume of the electronic screen being tested, the two sliding seats 8 on the same side slide in their respective sliding rails 7, thereby adjusting the position of the suction clamps 4. And because the two sliding rails 7 correspond to each other, the movement of the two sliding seats 8 remains corresponding.

[0036] An air-injection sealing assembly is provided between two suction clamps 4 located on the same side. The air-injection sealing assembly includes a connecting air pipe 10 and an exhaust pipe 11. The connecting air pipe 10 connects the bottom of the two suction clamps 4, and the exhaust pipe 11 connects the middle of the connecting air pipe 10. A solenoid valve is provided 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 connecting air pipe 10, so that the suction clamp 4 performs vacuum adsorption on the electronic screen and fixes the electronic screen on the positioning tray 3. The suction clamp 4 is a common prior art device used for adsorption and clamping of smooth parts, and is a prior art device known to those skilled in the art.

[0037] A calibration component is provided on one side of the rotating mounting assembly. The calibration component is used to adjust the position of the suction clamp 4 on the positioning tray 3. The calibration component includes a movable slide 12 and a first electric cylinder 14. There are two movable slides 12, which are located inside the detection platform 1. Two calibration blocks 13 are slidably arranged opposite each other inside the movable slide 12. An electromagnetic connector is provided between the calibration blocks 13 and the sliding seat 8. The electromagnetic connector includes an electromagnet 15. An electromagnet 15 is provided on both calibration blocks 13. An iron strip 16 is provided on the sliding seat 8. The electromagnet 15 and the iron strip 16 are magnetically connected. Next, two first electric cylinders 14 are set in the detection platform 1. The output end of the first electric cylinder 14 is fixedly connected to the moving slide 12. When it is necessary to adjust the position of the suction clamp 4, the first electric cylinder 14 is activated to push the moving slide 12 and the correction block 13 to move towards the sliding seat 8, so that the electromagnet 15 is in contact with the iron strip 16. Then, the electromagnet 15 is powered to generate magnetism, so that the correction block 13 and the sliding seat 8 are magnetically connected. During the process of the first electric cylinder 14 pushing the moving slide 12, the correction block 13 can drive the sliding seat 8 and the suction clamp 4 to move in the sliding track 7.

[0038] A bidirectional screw 17 is rotatably connected inside the movable slide 12. The correction block 13 is threadedly connected to the bidirectional screw 17. A screw drive motor 18 is provided on the movable slide 12. The output end of the screw drive motor 18 is fixedly connected to the bidirectional screw 17. As the sliding seat 8 moves in the sliding track 7, the two sliding seats 8 on the same side will also move closer to each other. At this time, the screw drive motor 18 is started to drive the bidirectional screw 17 to rotate, so that the correction block 13 is adjusted in accordance with the moving path of the sliding seat 8. In addition, since the correction block 13 needs to adjust the suction clamps 4 in different positions in multiple positioning trays 3, the lateral position of the correction block 13 can also be adjusted using the bidirectional screw 17.

[0039] It also includes a suction coordination mechanism. A suction coordination mechanism is provided on one side of the rotating mounting assembly. The suction coordination mechanism cooperates with two gas injection sealing assemblies. The suction coordination mechanism includes a support plate 19 and a moving assembly. The support plate 19 is fixedly connected to the rotating mounting base 5. A vacuum pump 20 is provided on the support plate 19. A suction assembly is provided at the suction end of the vacuum pump 20. The suction assembly includes a sealing insert 21. The number of sealing inserts 21 corresponds one-to-one. All sealing inserts 21 are connected to the suction end of the vacuum pump 20. The sealing insert 21 cooperates with the inner wall of the exhaust pipe 11. One of the positioning trays 3 is moved to the top of the support plate 19. Then the electronic screen is placed between multiple suction clamps 4, so that the sealing insert 21 is moved into the corresponding exhaust pipe 11. Then the vacuum pump 20 is used to extract the gas between the suction clamp 4 and the electronic screen, so that the suction clamp 4 performs vacuum adsorption on the electronic screen.

[0040] The support plate 19 is provided with a moving component that drives the air intake component to move. The moving component includes a second electric cylinder 22, which is fixedly connected to the support plate 19. A connecting plate 23 is fixedly connected between the two sealing 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 cylinder 21, the second electric cylinder 22 is activated to drive the connecting plate 23 to rise, so that the sealing cylinder 21 enters the corresponding exhaust pipe 11.

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

[0042] Move one of the positioning trays 3 directly above the support plate 19, start the first electric cylinder 14 to push the moving slide 12 and the correction block 13 toward the sliding seat 8, so that the electromagnet 15 is in contact with the iron strip 16, and then power the electromagnet 15 to generate magnetism, so that the correction block 13 and the sliding seat 8 are magnetically connected. During the process of the first electric cylinder 14 pushing the moving slide 12, the correction block 13 can drive the sliding seat 8 and the suction clamp 4 to move in the sliding track 7, and start the screw drive motor 18 to drive the bidirectional screw 17 to rotate, so that the correction block 13 is adjusted in accordance with the moving path of the sliding seat 8, so that the position of the suction clamp 4 in the positioning tray 3 corresponds to the volume of the electronic screen.

[0043] Then, the electronic screen is placed between multiple suction clamps 4, and the second electric cylinder 22 is started to drive the connecting plate 23 to rise, so that the sealing insert 21 enters the corresponding exhaust pipe 11. The vacuum pump 20 is used to extract the gas between the suction clamp 4 and the electronic screen, so that the suction clamp 4 vacuum adsorbs the electronic screen. Then, the main spindle drive motor 6 is started to drive the rotary table and polygonal turntable 2 to rotate along the center point of the rotating mounting base 5, so that the electronic screen can measure between multiple measuring devices.

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