[0039] 2.5D and 3D glass cover plates are widely used in the fields of car curved screens, mobile phone curved screens, etc., which makes customers have higher and higher requirements for the polished surface of cover plate products. In order to meet customer requirements, cover plate products must be measured vertically before leaving the factory; for example, the arc edge thickness or arc edge width of the cover glass is measured using an image measuring instrument.

[0040] However, since 2.5D or 3D cover glass is not a regular flat plate and cannot be placed stably, the product is prone to shaking during the observation and measurement process, making it inconvenient to observe, which seriously affects the measurement results and even the final quality of the product.

[0041] The measuring jig provided in this embodiment cooperates with the receiving groove and the clamping part on the jig body so that the receiving groove and the clamping surface of the clamping part can play a dual role of fixing and limiting the glass plate to be measured, thereby ensuring that the glass plate to be measured can be stably maintained at the detection position, avoiding the problem of unstable placement affecting the measurement results and even the final quality of the product.

[0042] Example 1

[0043] Reference Figure 1 The present embodiment discloses a measuring jig, which comprises a jig body 1 and at least two clamping parts 2. The jig body 1 is provided with a receiving groove 11, so that at least part of the glass plate 3 to be measured can be inserted into the receiving groove 11 perpendicularly to the jig body 1, and the receiving groove 11 is transparent; at least two clamping parts 2 are spaced and movably arranged on both sides of the receiving groove 11 along a first direction a, and the weight of the clamping parts 2 is greater than or equal to the weight of the glass plate 3 to be measured, and the first direction a is the width direction of the receiving groove 11;

[0044] The clamping part 2 has a clamping surface. When at least two clamping parts 2 are in a first relative position relationship, the clamping surfaces of at least two clamping parts 2 are respectively attached to and in contact with two surfaces of the glass plate 3 to be tested in the thickness direction.

[0045] Specifically, in order to solve the problem that non-straight plate-shaped glass cannot be placed stably during vertical position measurement, which affects the measurement results and even the final quality of the product, the present embodiment provides a measuring fixture, which is provided with a receiving groove 11 on the fixture body 1 for accommodating and limiting the glass plate 3 to be measured once, and then at least two clamping parts 2 with specified weights are provided, so that at least two clamping parts 2 can stably clamp the glass plate 3 to be measured in the thickness direction to achieve secondary limiting, effectively ensuring the stable setting of the glass plate 3 to be measured on the measuring fixture, and avoiding the problem of displacement or skewness of the glass plate 3 to be measured during the measurement process.

[0046] Among them, the fixture body 1 is a rigid structure, which is a base structure of the measuring fixture, and can be, but not limited to, a plate-shaped, block-shaped, or frame-shaped structure, as long as it can provide a placement position for the glass plate 3 to be tested; in this embodiment, the fixture body 1 is preferably set to have a certain thickness to ensure that it has corresponding stability as a base, for example, the thickness of the fixture body 1 is at least 7mm acrylic plate. The receiving groove 11 is excavated along the thickness direction of the fixture body 1, and the width of the receiving groove 11 corresponds to the thickness direction of the glass plate 3 to be tested. The length direction of the receiving groove 11 can be a linear direction or a non-linear direction, and it can be adapted to the shape of the glass plate 3 to be tested. In this embodiment, the receiving groove 11 is a transparent structure, which can be, but not limited to, glass material, acrylic material, etc., to ensure that the detection light source from top to bottom or from bottom to top can be illuminated through the glass plate 3 to be tested and the receiving groove 11; the receiving groove 11 can be integrally formed with the fixture body 1, or it can be additionally arranged on the fixture body. In this embodiment, the width of the receiving groove 11 is at least greater than the maximum thickness of the glass plate 3 to be tested, so as to ensure that the glass plate 3 to be tested can be inserted into the receiving groove 11. The maximum thickness of the glass plate 3 to be tested is the sum of its own thickness and the width of the arc edge.

[0047] The clamping part 2 is a rigid structure, which can be but not limited to iron, stainless steel, etc. It has a clamping surface, which can be a flat surface or a surface with a concave-convex structure, as long as it can be compatible with the glass plate 3 to be tested. In this embodiment, at least two clamping parts 2 are set to ensure that there is at least one clamping part 2 on both sides of the receiving groove 11 in the width direction to achieve the clamping of the glass plate 3 to be tested. There can be one clamping part 2 on each side of the receiving groove 11, or multiple on one side, or multiple on both sides. The shape of the clamping part 2 in this embodiment is not limited, and can be Figure 2 The triangle shown can also be Figure 3The strip-shaped one shown in the figure only needs to ensure that its weight is greater than or equal to the weight of the glass plate 3 to be tested, so as to ensure its stability when clamping the glass plate 3 to be tested, and avoid displacement or skew due to the resistance force of the glass plate 3 to be tested. In this embodiment, the clamping part 2 can be detachably arranged or movably arranged on the fixture body 1, for example, flipping, sliding, etc. When the clamping part 2 is detachably arranged, after inserting the glass plate 3 to be tested, the clamping part 2 is manually placed on the fixture body 1 and pushed to the first relative position relationship, and the first relative position relationship is that all the clamping surfaces of the clamping part 2 are in contact with and in contact with the surface of the glass plate 3 to be tested; when the clamping part 2 is movably arranged on the fixture body 1, when the glass plate 3 to be tested is not inserted, the clamping part 2 is moved so that the receiving groove 11 is completely exposed, and after inserting the glass plate 3 to be tested, the clamping part 2 is moved to the first relative position relationship state for clamping. Furthermore, it is understandable that the at least two clamping portions 2 may be directly opposite or staggered in the first direction a, as long as they are able to maintain a stable hold on the glass plate 3 to be tested.

[0048] According to the above, the measuring jig provided in this embodiment, through the cooperation between the receiving groove 11 on the jig body 1 and the clamping part 2, enables the receiving groove 11 and the clamping surface of the clamping part 2 to play a dual role of fixing and limiting the glass plate 3 to be measured, ensuring that the glass plate 3 to be measured can be stably maintained in the detection position, avoiding the problem of unstable placement affecting the measurement results and even the final quality of the product.

[0049] The term "and / or" in this article is merely a description of the association relationship of associated objects, identifying three possible relationships. For example, A and / or B is specifically understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0050] In some embodiments, refer to the attached Figure 2 , Attachment Figure 3 And attached Figure 4 In the measuring jig provided in this embodiment, the sum of the depth of the receiving groove 11 and the thickness of the clamping portion 2 is smaller than the dimension of the glass plate 3 to be measured in the direction perpendicular to the jig body 1 .

[0051] Specifically, in order to ensure the accuracy of the measurement results, in this embodiment, the sum of the depth of the accommodating groove 11 and the thickness of the clamping portion 2 is set to be smaller than the size of the glass plate 3 to be tested in the direction perpendicular to the fixture body 1, so that after the glass plate 3 to be tested is positioned and clamped, the edge or vertical position to be tested remains exposed outside the clamping portion 2, and then when performing lighting detection, the refraction of light in the glass plate 3 to be tested will not be affected by the clamping portion 2, thereby effectively ensuring the accuracy of the test results.

[0052] Furthermore, in some embodiments, in the measuring jig provided in the present embodiment, when at least two clamping parts 2 are in a first relative position relationship, the effective dimension of at least two clamping parts 2 overlapping along the second direction b is at least 1 / 2 of the dimension of the glass plate 3 to be measured in the second direction b; wherein the second direction b is the length direction of the accommodating groove 11; the effective dimension is the sum of the dimension of the clamping part 2 along the second direction b and the dimension of other clamping parts 2 that do not overlap with it in the second direction b.

[0053] Specifically, in order to ensure stable clamping of the glass plate 3 to be tested, in this embodiment, the size of the clamping portion 2 in the second direction b is set to ensure that at least 1 / 2 of the size of the glass plate 3 to be tested in the length direction of the receiving groove 11 is clamped, so as to avoid the glass plate 3 to be tested from shifting or tilting due to unstable clamping. When there are only two clamping portions 2, the two clamping portions 2 can be arranged according to Figure 3 In the state shown, the clamping is performed face to face, and at this time, the size of each clamping part 2 along the second direction b is at least half of the glass plate 3 to be tested in this direction; the two clamping parts 2 can also be arranged alternately in the second direction b, and there can be overlapping parts in the interleaving process, or there can be no overlapping parts, that is, the two clamping parts 2 are connected in the first position. When there are more than three clamping parts 2, two clamping parts 2 can be arranged on one side of the accommodating groove 11, and one clamping part 2 can be arranged on the other side. The two clamping parts 2 on the same side can be arranged continuously or at intervals. The clamping part 2 on one side can be arranged in the middle or between the two clamping parts 2, as long as the clamping length for the glass plate 3 to be tested meets 1 / 2 of its length.

[0054] Further, in some embodiments, referring to the attached Figure 3 and attached Figure 5 In the measuring jig provided in this embodiment, the clamping portion 2 is slidably connected to the jig body 1 along the first direction a; the jig body 1 is provided with guide grooves 12 on both sides of the accommodating groove 11, and the guide grooves 12 extend along the first direction a; the clamping portion 2 is provided with a sliding portion 21 adapted to the guide groove 12; wherein, a plurality of limiting portions 4 are provided in the guide groove 12, the limiting portions 4 are elastic, and the limiting portions 4 extend toward the direction of the accommodating groove 11 at a specified angle with the first direction a.

[0055] Specifically, in order to realize the mobility of the clamping part 2 and improve the convenience of operation, in this embodiment, the clamping part 2 is set to be in a form of sliding connection with the fixture body 1, a guide groove 12 is set on the fixture body 1, and a sliding part 21 is correspondingly set on the clamping part 2. The sliding part 21 can be but not limited to a slider, a pulley, a roller, etc. At the same time, in order to enable the clamping part 2 to maintain the first relative position relationship, in this embodiment, a plurality of limiting parts 4 are set at the bottom of the guide groove 12. The limiting parts 4 extend from the bottom of the guide groove 12 to the notch and extend obliquely toward the receiving groove 11, so that when the sliding part 21 moves toward the receiving groove 11, the limiting parts 4 can use their own elasticity to get close to the bottom of the guide groove 12. However, when the sliding part 21 is in place, the limiting parts 4 will use their own extension direction to block the sliding part 21 from being away from the receiving groove 11, thereby ensuring that when there is no large external force, the clamping part 2 will not move in the direction to affect the clamping effect.

[0056] In some embodiments, refer to the attached Figure 1 In the specific implementation of the measuring jig provided in this embodiment, the jig body 1 includes at least a right-angle portion for adapting to a right-angle support block (not shown in the figure) of a detection device (not shown in the figure).

[0057] Specifically, in order to improve the measurement efficiency, in this embodiment, the shape of the fixture body 1 is set to include at least one right-angle portion, or it can be a rectangular parallelepiped with four right-angle portions, so that it can be quickly and accurately positioned when cooperating with the right-angle support block on the existing positioning fixture, and also provide accurate coordinate points for the image acquisition device.

[0058] In some embodiments, in the measuring jig provided in this embodiment, in a specific implementation, at least the clamping surface of the clamping portion 2 is covered with a protective film (not shown in the figure).

[0059] Specifically, in order to ensure the surface quality of the glass plate 3 to be tested and avoid being scratched by the clamping part 2, a protective film is provided on the clamping surface of the clamping part 2 in this embodiment. The protective film is a flexible film layer, which can be but is not limited to Teflon tape, thereby ensuring that the surface of the clamping surface facing the glass plate 3 to be tested is smooth and elastic, thereby avoiding scratching the glass plate 3 to be tested.
