[0029] The following mainly describes the embodiments of the present application in conjunction with the accompanying drawings.

[0030] The present application proposes a substrate scribe line detection device 100, referring to Figure 1 and Figure 2 , which includes a conveying mechanism 110, a scribe line detection member 120 and a lifting mechanism 130. The conveying mechanism 110 has a detection station, and the conveying mechanism 110 drives the substrate 140 to move and pass through the detection station; the scribe line detection member 120 is installed above the detection station; the lifting mechanism 130 is installed below the detection station, and when the substrate 140 is in the detection station, the lifting mechanism 130 lifts the substrate 140 upward and horizontally away from the conveying mechanism 110 and close to the scribe line detection member 120.

[0031] In the present application, the conveying mechanism 110 drives the substrate 140 to move and pass through the inspection station, and the lifting mechanism 130 located below the inspection station lifts the substrate 140 to separate it from the conveying mechanism 110 and approach the line detection part 120 located above the inspection station, so that the position of the substrate 140 no longer moves during the inspection process, and by lifting the substrate 140 away from the conveying surface, it can be ensured that the substrate 140 is in a horizontal state, and the laser line is relative to the line detection part 120, thereby increasing the inspection accuracy; in addition, there is no need to remove the photovoltaic substrate 140 from the production line, the inspection process is simple, and the inspection efficiency is high, so that the production can proceed smoothly, the line detection part 120 can detect each substrate 140, the inspection data volume is large, the inspection results are accurate, the objectivity is strong, and the error is reduced.

[0032] Understandably, referring to Figure 1 and Figure 2 The substrate marking line detection device 100 has a front-to-back direction X, a left-to-right direction Y and an up-to-down direction Z, wherein the front-to-back direction X is the conveying direction of the conveying mechanism 110, the left-to-right direction Y is a direction in a horizontal plane perpendicular to the conveying direction, and the up-to-down direction Z is a direction perpendicular to the horizontal plane.

[0033] It should be noted that the line detection component 120 is a visual detection module, which in some embodiments specifically includes an integrated or separately arranged light source device and a visual camera; the light emitted by the light source device at least covers the detection station; the visual camera has high sensitivity and high resolution, and can clearly capture the appearance image of the substrate including the line condition.

[0034] In some embodiments, reference Figure 2 The conveying mechanism 110 includes at least two sets of secondary conveying mechanisms 111 arranged at intervals perpendicular to the conveying direction, and a movable channel A is formed between the secondary conveying mechanisms 111 for the lifting mechanism 130 to move through.

[0035] Specifically, in some embodiments, the conveying mechanism 110 may be a conventional belt conveying mechanism 110, and the belt surface width is relatively small. Figure 2 Two conveyor belts spaced apart along the left-right direction Y drive the conveyor substrate 140, that is, the conveyor belts are arranged corresponding to the edge area of ​​the substrate 140, the substrate 140 is mounted on the two conveyor belts and moves forward, and a movable channel A is formed between the two conveyor belts for the lifting mechanism 130 to move through.

[0036] In some embodiments, reference Figure 1The lifting mechanism 130 includes a support frame 131 and a lifting part 132. The support frame 131 is arranged below the detection station. The lifting part 132 is installed on the support frame 131 to move up and down. The lifting part 132 can pass through the conveying mechanism 110 and abut against the substrate 140 to be tested. Further, in some embodiments, the support frame 131 is provided with a plurality of groups of distributed lifting parts 132. The lifting parts 132 are lifting mechanisms or telescopic mechanisms. Each lifting part 132 can independently move and adjust the lifting height. Further, in some embodiments, the horizontality of the substrate 140 on the conveying mechanism 110 is H1, and the horizontality of the substrate 140 when being lifted by the lifting mechanism 130 is H2, then H2<

[0037] Specifically, in some embodiments, in combination Figure 1 and Figure 2 The lifting portion 132 of the lifting mechanism 130 passes through the active channel A between the two sets of secondary conveying mechanisms 111, directly or indirectly contacts the substrate 140, and lifts the substrate 140 upward, so that the substrate 140 remains horizontal, thereby increasing the detection accuracy.

[0038] It should be noted that the smaller the value of the levelness is, the closer it is to the horizontal state. When the substrate 140 is on the conveying mechanism 110, the levelness value of the substrate 140 is relatively large due to factors such as the manufacturing quality of the conveying surface of the conveying mechanism 110 and the conveying vibration. When the substrate 140 is lifted by the lifting part 132, its levelness is much smaller than the levelness when it is placed on the conveying mechanism 110, and is closer to the horizontal direction.

[0039] In some embodiments, the substrate marking line detection device 100 further includes a positioning mechanism 150 , which is installed on the support frame 131 for vertical movement. The positioning mechanism 150 can horizontally limit the position of the substrate 140 to be tested on the detection station.

[0040] The positioning mechanism 150 has multiple implementations, and may include at least the following two embodiments:

[0041] In one embodiment, the positioning mechanism 150 includes two movable positioning members 151 that can be limited to at least one set of diagonal corners of the substrate 140, and the two movable positioning members 151 centrally position the substrate 140 in a direction perpendicular to the conveying direction.

[0042] In another embodiment, the positioning mechanism 150 includes four groups of movable positioning members 151 that can be respectively limited to the four sides of the substrate 140, each group of movable positioning members 151 includes at least two spaced apart along the edge of the substrate 140, and the four groups of movable positioning members 151 center the substrate 140 in four directions.

[0043] Further, in some embodiments, referring to Figure 2 ​, each edge of the substrate 140 is limited by two groups of movable positioning members 151, that is, a total of eight groups of movable positioning members 151 are provided to limit the four sides of the substrate 140. Furthermore, in some embodiments, the movable positioning member 151 includes a lifting module 1511 and a movable block 1512 provided on the lifting end of the lifting module 1511, and the movable block 1512 is lifted and displaced relative to the conveying surface of the conveying mechanism 110 in the normal direction of the substrate 140, and the movable block 1512 has a retracted state below the conveying surface and a positioned state above the conveying surface.

[0044] Specifically, in the above embodiment, when the substrate 140 is moved to the detection station under the drive of the conveying mechanism 110, a plurality of positioning members cooperate with each other to center and position the substrate 140, so that the substrate 140 corresponds to the line detection member 120 along the up and down direction Z, thereby realizing the limitation of the substrate 140 in the horizontal direction; wherein, the movable block 1512 of the positioning member is in direct contact with the edge of the substrate 140, and the movable block 1512 can be made of soft material or wrapped with a protective layer to avoid pinching the substrate 140; when the lifting mechanism 130 lifts the substrate 140, the movable block 1512 rises synchronously with the substrate 140 under the drive of the lifting module 1511, so that the substrate 140 remains stable during the rising process, thereby improving the detection accuracy.

[0045] See attached Figure 3 In some embodiments, a vacuum adsorption tray 200 is provided at the top of the lifting mechanism 130, and the vacuum adsorption tray 200 is used to lift and adsorb the substrate 140 to be tested. The support and adsorption of the substrate 140 to be tested by the vacuum adsorption tray can, on the one hand, ensure the relative position of the substrate 140 and the lifting mechanism 130 and the stability during the lifting movement; on the other hand, since the width of the laser line groove is only about 100μm, the large area contact between the vacuum adsorption tray 200 and the substrate 140 can prevent the deformation of the substrate 140 and the line groove, thereby improving the line detection accuracy.

[0046] In some embodiments, the conveying mechanism 110 includes a front-section conveying mechanism 1101, a middle-section conveying mechanism 1102, and a rear-section conveying mechanism 1103 which are spaced apart in the conveying direction; the vacuum adsorption tray 200 is an integral structure, and a through groove 210 is provided on the vacuum adsorption tray 200 along the lifting direction, and the orthographic projection of the middle-section conveying mechanism 1102 in the lifting direction is located in the through groove 210.

[0047] The substrate 140 is sequentially conveyed by the front conveying mechanism 1101, the middle conveying mechanism 1102 and the rear conveying mechanism 1103; the lifting mechanism 130 and the vacuum adsorption tray 200 have a lifting state and an initial state. In the initial state, the lifting mechanism 130 retracts, and the vacuum adsorption tray 200 is located below the conveying surface, that is, the upper surface of the vacuum adsorption tray 200 is lower than the upper conveying surface of the middle conveying mechanism 1102. The middle conveying mechanism 1102 conveys the substrate to the inspection station, and then the lifting mechanism 130 lifts, so that the vacuum adsorption tray 200 rises until the vacuum adsorption tray contacts the substrate 140 and vacuum adsorbs the substrate 140.

[0048] In some embodiments, the vacuum adsorption tray 200 is provided with a plurality of peripheral positioning blocks 220 along the outer contour, and the plurality of peripheral positioning blocks 220 define a positioning space for positioning the substrate 140. The peripheral positioning blocks 220 may be fixed blocks, and are distributed around the vacuum adsorption tray 200.

[0049] In some embodiments, reference Figure 1 The substrate line detection device 100 further includes a displacement module 160 , which is disposed above the detection station, and the line detection member 120 is connected to the displacement module 160 by movement along the front-to-back direction X and / or the left-to-right direction Y.

[0050] Specifically, in this embodiment, refer to Figure 1 , the displacement module 160 can be installed on the rack of the device, and the displacement module 160 can be a one-dimensional module or a two-dimensional module, that is, the engraved line detection member 120 is arranged at the displacement end of the displacement module 160 along the front-back direction X and / or the left-right direction Y. In addition, in some embodiments, the displacement module 160 can also be a three-dimensional module, that is, the engraved line detection member 120 can be fine-tuned along the up-down direction Z in addition to horizontal displacement, so as to better focus and image, so that the result of detecting the engraved line is more accurate.

[0051] In particular, the term "and / or" in this application should be understood as follows:

[0052] First, the term “and / or” located between a first subject and a second subject includes any one of the following meanings: (1) only the first subject; (2) only the second subject; and (3) the first subject and the second subject.

[0053] Secondly, the term "and / or" between the last two entities among three or more entities refers to at least any one of the entities. For example, "the first entity, the second entity and / or the third entity" has the same meaning as "the first entity and / or the second entity and / or the third entity", specifically including the following combinations: (1) only the first entity; (2) only the second entity; (3) only the third entity; (4) the first entity and the second entity without the third entity; (5) the first entity and the third entity without the second entity; (6) the second entity and the third entity without the first entity; and (7) the first entity, the second entity, and the third entity.

[0054] In addition, although the above content describes the embodiments of the present application in conjunction with the accompanying drawings, those skilled in the art can also make various modifications and variations without departing from the concept of the present application, and such modifications and variations are all within the scope defined by the attached claims.
