Description

Technical Field

[0001] The utility model relates to a leveling jig for improving the ghosting of an electrochromic device. Background Art

[0002] At present, electrochromic devices are devices whose optical properties such as transmittance and reflectivity can undergo stable and reversible changes under the action of an external electric field. The specific structure of an electrochromic device is disclosed in the Chinese patent with the announcement number CN116449624A. Electrochromic devices are widely used in camera modules. After light passes through the electrochromic device, it enters the camera module and then forms an image on the display screen. At present, some existing electrochromic devices will be affected by the vacuum pressure during vacuum filling and thus deform and cause warping. When such a warped and uneven electrochromic device is used in a camera module, light passing through the warped electrochromic device will be reflected and refracted multiple times, resulting in ghosting during imaging, which reduces the quality of the image and causes dizziness in the user. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a leveling jig for improving the ghosting of electrochromic devices. The leveling jig can level the electrochromic devices during the production process, keep the electrochromic devices flat and avoid warping, and can be applied to camera modules to avoid the ghosting problem.

[0004] In order to solve the above technical problems, the technical solution of the present utility model is: a leveling jig for improving the ghosting of an electrochromic device, comprising a first body, a second body and a third body;

[0005] The electrochromic device includes a first conductive glass and a second conductive glass;

[0006] The first body is provided with a first positioning groove for placing and positioning the first conductive glass, and the center of the bottom wall of the first positioning groove is concave inward;

[0007] The second body is provided with a second positioning groove for placing and positioning the second conductive glass, and the center of the bottom wall of the second positioning groove is concave inward;

[0008] The first positioning groove is provided with a first adsorption hole for applying negative pressure to adsorb the first conductive glass onto the bottom wall of the first positioning groove;

[0009] The second positioning groove is provided with a second adsorption hole for applying negative pressure to adsorb the second conductive glass onto the bottom wall of the second positioning groove;

[0010] The first body is used to buckle with the second body to press the first conductive glass in the first positioning groove and the second conductive glass in the second positioning groove to form a box body;

[0011] The second body is provided with a reference plane portion, and the third body is provided with a pressing plane portion. When the third body is connected to the second body, a flattening gap for placing the box body is formed between the reference plane portion and the pressing plane portion. The pressing plane portion in the third body is used to press the box body against the reference plane portion, thereby flattening the first conductive glass and the second conductive glass in the box body.

[0012] A specific structure of the first body and the second body is further provided. The first body and the second body are both ceramic suction cups, and the first adsorption holes and the second adsorption holes are both micropores provided in the ceramic suction cups.

[0013] Furthermore, an adsorption positioning pin is provided on any one of the first body and the second body, and an adsorption positioning hole is provided on the other of the first body and the second body, and the adsorption positioning pin is used to be inserted into the adsorption positioning hole when the first body and the second body are buckled together.

[0014] Furthermore, a flattening positioning pin is provided on any one of the second body and the third body, and a flattening positioning hole is provided on the other of the second body and the third body, and the flattening positioning pin is used to be inserted into the flattening positioning hole when the third body is connected to the second body.

[0015] Furthermore, the third body is connected to the second body via fasteners.

[0016] Furthermore, the fastener is a bolt, the second body is provided with a threaded hole adapted to the bolt, the third body is provided with a through hole adapted to the bolt, and the bolt passes through the through hole and is connected in the threaded hole to lock the third body to the second body.

[0017] After adopting the above technical solution, a first conductive glass is placed in the first positioning groove with the conductive surface of the first conductive glass facing outward rather than inward. A second conductive glass is placed in the second positioning groove with the conductive surface of the second conductive glass facing outward rather than inward. A circle of unclosed dam glue is applied to either the first conductive glass or the second conductive glass. The dam glue has a pouring notch. Negative pressure is applied to the first adsorption hole to absorb and adhere the first conductive glass to the bottom wall of the first positioning groove. Negative pressure is applied to the second adsorption hole to absorb and adhere the second conductive glass to the bottom wall of the second positioning groove. The first body and the second body are then fastened together so that the first conductive glass in the first positioning groove and the second conductive glass in the second positioning groove are pressed together by the dam glue. The dam glue is then cured to form a box body. A filling gap is formed in the box body, located between the first conductive glass and the second conductive glass and inside the dam glue. Then, vacuum liquid is poured into the filling gap in the box body from the pouring gap, and then the box body is placed in the flattening gap. The box body is pressed against the reference plane portion through the pressing plane portion in the third body to flatten the first conductive glass and the second conductive glass in the box body, and then the pouring gap is sealed.

[0018] Because the centers of the bottom walls of the first and second positioning grooves are both recessed, applying negative pressure through the first adsorption hole to adsorb the first conductive glass against the bottom wall of the first positioning groove causes the first conductive glass to bulge and deform. Applying negative pressure through the second adsorption hole to adsorb the second conductive glass against the bottom wall of the second positioning groove causes the second conductive glass to bulge and deform. When the first and second conductive glasses are pressed together to form a box body, both the first and second conductive glasses within the box body bulge outward. During vacuum filling of the box body, the filling gap within the box body is evacuated. Consequently, during filling, the pressure outside the box body is greater than the pressure within the filling gap. The first and second conductive glasses within the box body are compressed toward the center due to the pressure differential between the inside and outside of the box body, resulting in a reduced outward bulge of the first and second conductive glasses within the box body, though the bulges remain. Among them, when the box body is placed in the flattening gap and the box body is pressed against the reference plane portion by pressing the plane portion, the first conductive glass and the second conductive glass in the box body are pressed inward and flattened. At this time, the first conductive glass and the second conductive glass are in a planar state, and then the pouring gap is sealed, so that the prepared electrochromic device can remain flat and avoid the phenomenon of warping and deformation. In summary, the leveling jig for improving the ghosting of the electrochromic device according to the embodiment of the present application can press the electrochromic device flat during the production process, can level the electrochromic device, keep the electrochromic device flat and avoid the occurrence of warping, and then when applied to the camera module, there will be no ghosting when the light passes through the flat electrochromic device, avoiding the occurrence of ghosting problems, improving the quality of imaging, avoiding dizziness of users, and is very convenient to operate, which can save costs and enable the electrochromic device to adapt to more application scenarios.

[0026] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figures 1 to 7 As shown, a leveling jig for improving ghosting of an electrochromic device includes a first body 1, a second body 2, and a third body 3;

[0029] The electrochromic device includes a first conductive glass 4 and a second conductive glass 5;

[0030] The first body 1 is provided with a first positioning groove 6 for placing and positioning the first conductive glass 4, and the center of the bottom wall of the first positioning groove 6 is concave inward;

[0031] The second body 2 is provided with a second positioning groove 7 for placing and positioning the second conductive glass 5, and the center of the bottom wall of the second positioning groove 7 is concave inward;

[0032] The first positioning groove 6 is provided with a first adsorption hole for applying negative pressure to adsorb the first conductive glass 4 onto the bottom wall of the first positioning groove 6;

[0033] The second positioning groove 7 is provided with a second adsorption hole for applying negative pressure to adsorb the second conductive glass 5 onto the bottom wall of the second positioning groove 7;

[0034] The first body 1 is used to buckle with the second body 2 to press the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 to form a box body 8;

[0035] The second body 2 is provided with a reference plane portion 9, and the third body 3 is provided with a pressing plane portion 10. When the third body 3 is connected to the second body 2, a flattening gap 11 for placing the box body 8 is formed between the reference plane portion 9 and the pressing plane portion 10. The pressing plane portion 10 in the third body 3 is used to press the box body 8 against the reference plane portion 9, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8.

[0036] Specifically, a first conductive glass 4 is placed in the first positioning groove 6 with the conductive surface of the first conductive glass 4 facing outward rather than inward. A second conductive glass 5 is placed in the second positioning groove 7 with the conductive surface of the second conductive glass 5 facing outward rather than inward. A ring of unclosed dam glue 12 is applied to either the first conductive glass 4 or the second conductive glass 5. The dam glue 12 has a pouring notch. Negative pressure is applied to the first adsorption hole to attract and adhere the first conductive glass 4 to the bottom wall of the first positioning groove 6. Negative pressure is applied to the second adsorption hole to attract and adhere the second conductive glass 5 to the bottom wall of the second positioning groove 7. The first body 1 and the second body 2 are then fastened together, pressing the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 together via the dam glue 12. The dam glue 12 is then cured to form a box body 8. A filling gap 13 is formed in the box body 8. The filling gap 13 is located between the first conductive glass 4 and the second conductive glass 5 and inside the dam glue 12. Then, vacuum liquid is poured into the filling gap 13 in the box body 8 from the pouring gap, and then the box body 8 is placed in the flattening gap 11. The box body 8 is pressed against the reference plane portion 9 through the pressing plane portion 10 in the third body 3, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8, and then the pouring gap is sealed.

[0037] More specifically, since the centers of the bottom walls of the first positioning groove 6 and the second positioning groove 7 are both recessed inward, when the first conductive glass 4 is adsorbed and attached to the bottom wall of the first positioning groove 6 by applying negative pressure through the first adsorption hole, the first conductive glass 4 can be convexly deformed. When the second conductive glass 5 is adsorbed and attached to the bottom wall of the second positioning groove 7 by applying negative pressure through the second adsorption hole, the second conductive glass 5 can be convexly deformed. Then, when the first conductive glass 4 and the second conductive glass 5 are pressed together to form the box body 8, the first conductive glass 4 and the second conductive glass 5 in the box body 8 will both convex outwardly, as shown in FIG. Figure 6 As shown in . More specifically, when the box body 8 is in the process of vacuum filling, the filling gap 13 in the box body 8 will be evacuated, and then during filling, the external pressure of the box body 8 is greater than the pressure in the filling gap 13. The first conductive glass 4 and the second conductive glass 5 in the box body 8 will be compressed toward the center under the action of the internal and external pressure difference, resulting in the first conductive glass 4 and the second conductive glass 5 in the box body 8 protruding outward to a reduced extent, but still in a state of protruding outward. More specifically, when the box body 8 is placed in the flattening gap 11 and the box body 8 is pressed against the reference plane portion 9 by the pressing plane portion 10, the first conductive glass 4 and the second conductive glass 5 in the box body 8 are both pressed inward and flattened. At this time, the first conductive glass 4 and the second conductive glass 5 are both in a planar state, as shown in FIG. Figure 7As shown in , the injection gap is then sealed, so that the electrochromic device can be kept flat and avoid warping and deformation. In summary, the leveling jig for improving the ghosting of electrochromic devices according to the embodiment of the present application can press the electrochromic device flat during the production process, can level the electrochromic device, keep the electrochromic device flat and avoid the occurrence of warping. When applied to the camera module, when light passes through the flat electrochromic device, ghosting will not occur, thus avoiding the occurrence of ghosting problems, improving the quality of imaging, avoiding dizziness in users, and is very convenient to operate, which can save costs and enable the electrochromic device to adapt to more application scenarios.

[0038] In this embodiment, both the first body 1 and the second body 2 are ceramic suction cups, and both the first adsorption holes and the second adsorption holes are micropores provided in the ceramic suction cups. As is well known, ceramic suction cups, also known as ceramic microporous suction cups or microporous ceramic vacuum suction cups, are provided with uniformly distributed micropores. When the gas in the micropores is evacuated, a negative pressure is generated, which can then be used to adsorb the product.

[0039] like Figure 1 、 3 As shown in Figures 4 and 5, any one of the first body 1 and the second body 2 is provided with an adsorption positioning pin 14, and the other one of the first body 1 and the second body 2 is provided with an adsorption positioning hole 15, and the adsorption positioning pin 14 is used to be inserted into the adsorption positioning hole 15 when the first body 1 and the second body 2 are buckled together, so that the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 can be aligned and pressed to form the box body 8; in this embodiment, the adsorption positioning pin 14 is provided on the first body 1 and is provided with two, and the adsorption positioning hole 15 is provided on the second body 2 and is provided with two.

[0040] like Figure 1 、 3As shown in Figures 4 and 5, a flattening positioning pin 16 is provided on any one of the second body 2 and the third body 3, and a flattening positioning hole 17 is provided on the other of the second body 2 and the third body 3. The flattening positioning pin 16 is used to be inserted into the flattening positioning hole 17 when the third body 3 is connected to the second body 2. Specifically, when the first conductive glass 4 and the second conductive glass 5 are both thin, the second body 2 is placed below, the third body 3 is placed above the second body 2, and the adsorption positioning pin 14 is inserted into the adsorption positioning hole 15. The box body 8 is placed in the flattening gap 11, and the third body 3 uses its own gravity to cause the pressing plane portion 10 to press the box body 8 against the reference plane portion 9, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8. In this embodiment, the flattening positioning pin 16 is provided on the third body 3, and the flattening positioning hole 17 is provided on the second body 2.

[0041] Example 2

[0042] like Figures 1 to 7 As shown, another leveling jig for improving ghosting of electrochromic devices includes a first body 1, a second body 2 and a third body 3;

[0043] The electrochromic device includes a first conductive glass 4 and a second conductive glass 5;

[0044] The first body 1 is provided with a first positioning groove 6 for placing and positioning the first conductive glass 4, and the center of the bottom wall of the first positioning groove 6 is concave inward;

[0045] The second body 2 is provided with a second positioning groove 7 for placing and positioning the second conductive glass 5, and the center of the bottom wall of the second positioning groove 7 is concave inward;

[0046] The first positioning groove 6 is provided with a first adsorption hole for applying negative pressure to adsorb the first conductive glass 4 onto the bottom wall of the first positioning groove 6;

[0047] The second positioning groove 7 is provided with a second adsorption hole for applying negative pressure to adsorb the second conductive glass 5 onto the bottom wall of the second positioning groove 7;

[0048] The first body 1 is used to buckle with the second body 2 to press the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 to form a box body 8;

[0049] The second body 2 is provided with a reference plane portion 9, and the third body 3 is provided with a pressing plane portion 10. When the third body 3 is connected to the second body 2, a flattening gap 11 for placing the box body 8 is formed between the reference plane portion 9 and the pressing plane portion 10. The pressing plane portion 10 in the third body 3 is used to press the box body 8 against the reference plane portion 9, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8.

[0050] Specifically, a first conductive glass 4 is placed in the first positioning groove 6 with the conductive surface of the first conductive glass 4 facing outward rather than inward. A second conductive glass 5 is placed in the second positioning groove 7 with the conductive surface of the second conductive glass 5 facing outward rather than inward. A ring of unclosed dam glue 12 is applied to either the first conductive glass 4 or the second conductive glass 5. The dam glue 12 has a pouring notch. Negative pressure is applied to the first adsorption hole to attract and adhere the first conductive glass 4 to the bottom wall of the first positioning groove 6. Negative pressure is applied to the second adsorption hole to attract and adhere the second conductive glass 5 to the bottom wall of the second positioning groove 7. The first body 1 and the second body 2 are then fastened together, pressing the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 together via the dam glue 12. The dam glue 12 is then cured to form a box body 8. A filling gap 13 is formed in the box body 8. The filling gap 13 is located between the first conductive glass 4 and the second conductive glass 5 and inside the dam glue 12. Then, vacuum liquid is poured into the filling gap 13 in the box body 8 from the pouring gap, and then the box body 8 is placed in the flattening gap 11. The box body 8 is pressed against the reference plane portion 9 through the pressing plane portion 10 in the third body 3, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8, and then the pouring gap is sealed.

[0051] More specifically, since the centers of the bottom walls of the first positioning groove 6 and the second positioning groove 7 are both recessed inward, when the first conductive glass 4 is adsorbed and attached to the bottom wall of the first positioning groove 6 by applying negative pressure through the first adsorption hole, the first conductive glass 4 can be convexly deformed. When the second conductive glass 5 is adsorbed and attached to the bottom wall of the second positioning groove 7 by applying negative pressure through the second adsorption hole, the second conductive glass 5 can be convexly deformed. Then, when the first conductive glass 4 and the second conductive glass 5 are pressed together to form the box body 8, the first conductive glass 4 and the second conductive glass 5 in the box body 8 will both convex outwardly, as shown in FIG. Figure 6As shown in . More specifically, when the box body 8 is in the process of vacuum filling, the filling gap 13 in the box body 8 will be evacuated, and then during filling, the external pressure of the box body 8 is greater than the pressure in the filling gap 13. The first conductive glass 4 and the second conductive glass 5 in the box body 8 will be compressed toward the center under the action of the internal and external pressure difference, resulting in the first conductive glass 4 and the second conductive glass 5 in the box body 8 protruding outward to a reduced extent, but still in a state of protruding outward. More specifically, when the box body 8 is placed in the flattening gap 11 and the box body 8 is pressed against the reference plane portion 9 by the pressing plane portion 10, the first conductive glass 4 and the second conductive glass 5 in the box body 8 are both pressed inward and flattened. At this time, the first conductive glass 4 and the second conductive glass 5 are both in a planar state, as shown in FIG. Figure 7 As shown in , the injection gap is then sealed, so that the electrochromic device can be kept flat and avoid warping and deformation. In summary, the leveling jig for improving the ghosting of electrochromic devices according to the embodiment of the present application can press the electrochromic device flat during the production process, can level the electrochromic device, keep the electrochromic device flat and avoid the occurrence of warping. When applied to the camera module, when light passes through the flat electrochromic device, ghosting will not occur, thus avoiding the occurrence of ghosting problems, improving the quality of imaging, avoiding dizziness in users, and is very convenient to operate, which can save costs and enable the electrochromic device to adapt to more application scenarios.

[0052] In this embodiment, both the first body 1 and the second body 2 are ceramic suction cups, and both the first adsorption holes and the second adsorption holes are micropores provided in the ceramic suction cups. As is well known, ceramic suction cups, also known as ceramic microporous suction cups or microporous ceramic vacuum suction cups, are provided with uniformly distributed micropores. When the gas in the micropores is evacuated, a negative pressure is generated, which can then be used to adsorb the product.

[0053] like Figures 2 to 5 As shown, either one of the first body 1 and the second body 2 is provided with an adsorption positioning pin 14, and the other one of the first body 1 and the second body 2 is provided with an adsorption positioning hole 15. The adsorption positioning pin 14 is used to be inserted into the adsorption positioning hole 15 when the first body 1 and the second body 2 are buckled together, so that the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 can be aligned and pressed to form a box body 8; in this embodiment, the adsorption positioning pin 14 is provided on the first body 1 and is provided with two, and the adsorption positioning hole 15 is provided on the second body 2 and is provided with two.

[0054] like Figure 2As shown, the third body 3 is connected to the second body 2 via a fastener, a bolt 18. The second body 2 is provided with a threaded hole 19 adapted to accommodate the bolt 18, and the third body 3 is provided with a through hole 20 adapted to accommodate the bolt 18. The bolt 18 passes through the through hole 20 and engages with the threaded hole 19, thereby locking the third body 3 to the second body 2. Specifically, when both the first conductive glass 4 and the second conductive glass 5 are relatively thick, the weight of the third body 3 itself cannot flatten the first and second conductive glasses 4, 5 in the box body 8. Therefore, the bolt 18 is required to lock the third body 3 to the second body 2, and the pressing plane 10 in the third body 3 presses the box body 8 against the reference plane 9, thereby flattening the first and second conductive glasses 4, 5 in the box body 8.

[0055] In summary, the first conductive glass 4 is placed in the first positioning groove 6 with the conductive surface of the first conductive glass 4 facing outward rather than inward. The second conductive glass 5 is placed in the second positioning groove 7 with the conductive surface of the second conductive glass 5 facing outward rather than inward. A circle of unclosed dam glue 12 is applied to either the first conductive glass 4 or the second conductive glass 5. The dam glue 12 has a pouring notch. Negative pressure is applied to the first adsorption hole to attract and adhere the first conductive glass 4 to the bottom wall of the first positioning groove 6. Negative pressure is applied to the second adsorption hole to attract and adhere the second conductive glass 5 to the bottom wall of the second positioning groove 7. The first body 1 and the second body 2 are then fastened together, pressing the first conductive glass 4 in the first positioning groove 6 and the second conductive glass 5 in the second positioning groove 7 together via the dam glue 12. The dam glue 12 is then cured to form a box body 8. A filling gap 13 is formed in the box body 8. The filling gap 13 is located between the first conductive glass 4 and the second conductive glass 5 and inside the dam glue 12. Then, vacuum liquid is poured into the filling gap 13 in the box body 8 from the pouring gap, and then the box body 8 is placed in the flattening gap 11. The box body 8 is pressed against the reference plane portion 9 through the pressing plane portion 10 in the third body 3, thereby flattening the first conductive glass 4 and the second conductive glass 5 in the box body 8, and then the pouring gap is sealed.

[0056] Because the centers of the bottom walls of the first positioning groove 6 and the second positioning groove 7 are both recessed, applying negative pressure through the first adsorption hole to adsorb the first conductive glass 4 against the bottom wall of the first positioning groove 6 causes the first conductive glass 4 to bulge and deform. Applying negative pressure through the second adsorption hole to adsorb the second conductive glass 5 against the bottom wall of the second positioning groove 7 causes the second conductive glass 5 to bulge and deform. When the first and second conductive glasses 4, 5 are pressed together to form the box body 8, both the first and second conductive glasses 4, 5 within the box body 8 bulge outward. During the vacuum filling process of the box body 8, the filling gap 13 within the box body 8 is evacuated. Consequently, during filling, the pressure outside the box body 8 is greater than the pressure within the filling gap 13. As a result, the first and second conductive glasses 4, 5 within the box body 8 are compressed toward the center due to the internal and external pressure differential. This results in a reduced degree of outward bulge in the first and second conductive glasses 4, 5 within the box body 8, though the bulges remain. Among them, when the box body 8 is placed in the flattening gap 11 and the box body 8 is pressed against the reference plane portion 9 by the pressing plane portion 10, the first conductive glass 4 and the second conductive glass 5 in the box body 8 are pressed inward and flattened. At this time, the first conductive glass 4 and the second conductive glass 5 are both in a planar state. Then, the pouring gap is sealed, so that the electrochromic device can be kept flat and the phenomenon of warping and deformation can be avoided. In summary, the leveling jig for improving the ghosting of the electrochromic device according to the embodiment of the present application can press the electrochromic device flat during the production process, can level the electrochromic device, keep the electrochromic device flat and avoid the occurrence of warping. When applied to the camera module, when the light passes through the flat electrochromic device, no ghosting will occur, thus avoiding the occurrence of ghosting problems, improving the quality of imaging, avoiding dizziness of the user, and being very convenient to operate, which can save costs and enable the electrochromic device to adapt to the needs of more application scenarios.
