Description

Technical Field

[0001] The invention relates to the field of detection facilities, and in particular to a device for detecting the curvature of a curved skylight glass substrate. Background Art

[0002] Skylight glass refers to transparent or translucent materials installed on the top of the car. Some sightseeing cars often install some customized curved skylight glass on the roof to improve the light inside the car, provide a better viewing experience, and improve aesthetics. When producing customized curved skylight glass, matching special-shaped glass substrates are often used to assist in production.

[0003] In order to ensure the production quality of glass, it is necessary to test the curvature of special-shaped glass substrates to ensure that the curvature of the glass after production meets the standards. However, when testing some special-shaped glass substrates, traditional testing facilities cannot accurately find the middle position of the arc segment of the glass substrate, resulting in that the detection end of the testing facility does not fall completely on the arc surface of the glass substrate during testing, resulting in inaccurate curvature detection results. At the same time, after the test, the test personnel need to read the test value before they can compare it to determine whether it is qualified. The reading process is quite cumbersome, resulting in inconvenient testing. Summary of the invention

DETAILED DESCRIPTION

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] like Figure 1-Figure 6 The arc detection device of the arc-shaped skylight glass substrate shown in the figure comprises an L-shaped centering frame 1, one end of the L-shaped centering frame 1 is inlaid with a card edge seat 2, and the other end of the L-shaped centering frame 1 is inlaid with a center frame 3, the spacing between the center frame 3 and the card edge seat 2 is the same as the distance between the horizontal section of the glass substrate 35 and the center of the arc section, so that when the card edge seat 2 is engaged with the edge of the plane section of the glass substrate 35, the height of the center frame 3 can be just flush with the center of the arc section of the glass substrate 35, and two centering plates 33 are symmetrically fixedly installed at one end of the center frame 3, and joints 34 are extended at the ends of the two centering plates 33, and the total length of the centering plates 33 and the joints 34 is the same as the radius of the arc section of the glass substrate 35 , when the joint 34 at the end of the centering plate 33 is pressed against the inner surface of the arc segment of the glass substrate 35, the center frame 3 can just coincide with the center of the arc segment of the glass substrate 35, and a moving part is installed at the other end of the center frame 3, and a bearing column 14 is connected to the end of the moving part, and a detection part is installed on the outer surface of the bearing column 14, and a fixing sleeve 22 is coaxially inlaid on the rear end of the bearing column 14, and a pressure head 21 is fixedly installed on the outer surface of the fixing sleeve 22, and the fixing sleeve 22 plays a role in fixing the pressure head 21, and the pressure head 21 can be pressed tightly on the outer surface of the arc segment of the glass substrate 35 to fix the center frame 3 that coincides with the center of the arc segment of the glass substrate 35, so as to avoid displacement of the center frame 3 during detection.

[0025] The contact surface of the joint 34 and the contact surface of the pressure head 21 are both arc-shaped, which can ensure that the arc segments of the joint 34, the pressure head 21 and the glass substrate 35 are in full contact. The rear edge of the inner surface of the clamping seat 2 is inclined, which can facilitate the clamping seat 2 to be clamped on the glass substrate 35.

[0026] The movable part includes a carrier shell 4 horizontally embedded in the other end of the center frame 3, and a guide rib 23 is slidably installed inside the carrier shell 4. The carrier shell 4 and the guide rib 23 play a role in horizontally guiding the bearing column 14. The end of the guide rib 23 passes through the end of the carrier shell 4, and the front end of the bearing column 14 is coaxially embedded with a column sleeve 31. The column sleeve 31 plays a role in fixing the bearing column 14, and the end of the guide rib 23 is fixed to the column sleeve 31.

[0027] A threaded rod 5 is installed at the lower end of the carrier shell 4, and a threaded sleeve 26 is screwed on the outer surface of the threaded rod 5. The threaded rod 5 can drive the threaded sleeve 26 to move, and then drive the bearing column 14 to move, so that the pressure head 21 on the bearing column 14 can be pressed against the outer surface of the arc segment of the glass substrate 35. A sleeve ear 27 extends from the upper end surface of the threaded sleeve 26. The sleeve ear 27 plays a role in pushing the bearing column 14, and the end of the sleeve ear 27 is connected to the column sleeve 31.

[0028] Both ends of the threaded rod 5 are coaxially rotatably installed with rod seats 28, which are fixed to the carrier shell 4. The rod seats 28 play a role in supporting the threaded rod 5. The lower end of the column sleeve 31 is fixedly installed with a connecting frame 30, and the end of the connecting frame 30 is fixed to the sleeve ear 27. The connecting frame 30 plays a role in fixing the column sleeve 31 and the sleeve ear 27 together. A hand wheel 29 is coaxially fixedly installed on the side of the threaded rod 5, and the hand wheel 29 plays a role in facilitating the rotation of the threaded rod 5.

[0029] The detection part includes an angle plate 10 embedded in the outer surface of a bearing column 14. The bearing column 14 is located at the measuring point of the angle plate 10, which can ensure that when the detection frame 8 rotates with the bearing column 14 as the center, it can synchronously rotate with the measuring point of the angle plate 10 as the center. Two frame sleeves 24 are fixedly installed on the outer surface of the bearing column 14 near the front of the angle plate 10. The outer surfaces of the two frame sleeves 24 are fixedly installed with indicator frames 6. The frame sleeves 24 play a role in connecting the indicator frames 6. The two indicator frames 6 are arranged oppositely. The ends of the two indicator frames 6 are fixedly installed with reference pieces 12. The angle indicated by the indicator frame 6 is the same as the angle detected by the qualified glass substrate 35, so that when the reference piece 12 on the indicator frame 6 is used as a reference point for identification, it can accurately identify whether the curvature of the glass substrate 35 is qualified, that is, in subsequent detection, the position of the detection piece 11 is aligned with the position of the reference piece 12, which indicates that the curvature of the glass substrate 35 is qualified. If the detection piece 11 is not aligned with the reference piece 12, it indicates that the curvature of the glass substrate 35 is unqualified.

[0030] Two connecting sleeves 16 are respectively installed on the outer surface of the bearing column 14 near the rear of the angle plate 10, and the two connecting sleeves 16 are fitted together. Two positioning rings 15 are coaxially inlaid on the outer surface of the bearing column 14, and the two connecting sleeves 16 are fitted between the two positioning rings 15. The positioning rings 15 prevent the connecting sleeves 16 from moving forward and backward. The outer surfaces of the two connecting sleeves 16 are fixedly installed with detection frames 8. The connecting sleeves 16 allow the detection frames 8 to rotate around the bearing column 14. The two detection frames 8 are arranged oppositely. Fixed ball frames 32 are fixedly installed at the ends of the two detection frames 8. Detection balls 25 are inlaid at the ends of the fixed ball frames 32. The fixed ball frames 32 fix the detection balls 25. The spherical setting of the detection ball 25 can enable it to fully contact the arc segment of the glass substrate 35 during detection. An extension frame 9 is extended from the inner surface of the detection frame 8. A detection piece 11 is fixedly installed at the end of the extension frame 9. The extension frame 9 serves to fix the detection piece 11. The detection piece 11 corresponds to the reference piece 12. A mirror frame 13 is fixedly installed at the front end edge of the indicator frame 6. A magnifying lens 7 is installed inside the mirror frame 13. The mirror frame 13 serves to carry the magnifying lens 7. The magnifying lens 7 corresponds to the joint between the detection piece 11 and the reference piece 12. The magnifying lens 7 can magnify the detection piece 11 and the reference piece 12 to clearly and accurately see whether the detection piece 11 and the reference piece 12 are aligned.

[0031] The lower end surface of the connecting sleeve 16 is inlaid with a column frame 20, and the lower end of the column frame 20 is penetrated by a limiting column 19 that is slidably installed. The column frame 20 plays a role in supporting the limiting column 19, and the limiting column 19 extends into the interior of the column frame 20. A top block 17 is fixedly installed on the upper end of the limiting column 19, and the limiting column 19 plays a role in guiding the top block 17. The top block 17 passes through the outer surface of the connecting sleeve 16, and the top block 17 slides with the connecting sleeve 16. The upper end of the top block 17 is pressed against the outer surface of the bearing column 14, which can increase the resistance of the detection frame 8 during rotation to avoid the detection frame 8 being too flexible and affecting its use. A tightening spring 18 is wound around the outer side of the limiting column 19, and one end of the tightening spring 18 is fixed to the inner lower end of the column frame 20. The tightening spring 18 plays a role in tightening the top block 17 against the bearing column 14, and the other end of the tightening spring 18 is fixed to the lower end of the top block 17.

[0032] During the inspection, the glass substrate 35 is first placed on the table and supported by the table. At this time, the arc section of the glass substrate 35 is located on the side of the table, and the edge of the glass substrate 35 extends out of the table. Then, the edge holder 2 is clamped at the edge of the plane section of the glass substrate 35 to position the center frame 3 so that the height of the center frame 3 is flush with the center of the arc section of the glass substrate 35. Then, the center frame 3 is pushed so that the joint 34 at the end of the centering plate 33 can be pressed against the inner surface of the arc section of the glass substrate 35, so that the center frame 3 can coincide with the center of the arc section of the glass substrate 35, so that the bearing column 14 can accurately correspond to the middle of the arc section of the glass substrate 35. Then, the threaded rod 5 is rotated to move the threaded sleeve 26 tightened on the threaded rod 5, thereby driving the bearing column 14 to move. At this time, the guide edge 23 is at the bearing column 14. The two detection frames 8 are then moved to rotate around the bearing column 14 to drive the two detection balls 25 to move. During this process, the detection sheet 11 on the extension frame 9 moves synchronously with the detection balls 25. When the two detection balls 25 are respectively pressed against the two sides of the arc segment of the glass substrate 35, the detection sheet 11 is aligned with the reference sheet 12 through the magnifying glass 7. If the detection sheet 11 is aligned with the reference sheet 12, it indicates that the curvature of the glass substrate 35 is qualified. If the detection sheet 11 is not aligned with the reference sheet 12, it indicates that the curvature of the glass substrate 35 is unqualified.
