[0036] The mainstream back glass products for current solar (photovoltaic) modules are mainly mesh-coated films. For this type of gap-coated glass, an automatic film applicator is needed to attach the film strip to the back glass, creating a mesh-like structure within the glass. The automatic film applicator's dimensions are set according to the drawing specifications. To ensure that the film strip's position on the glass conforms to the drawing requirements, after the first application, inspectors must use a steel tape measure or ruler to take measurements. Because there are many measurement points, each measurement results in significant downtime. However, failing to take measurements risks batch defects, severely impacting production cycle time, yield improvement, and increasing labor costs.

[0037] See Figure 1 As shown, a measuring fixture 100 according to some embodiments of this application includes a positioning element 1 and a measuring element 2. The positioning element 1 is configured to position and cooperate with the product to be tested. The measuring element 2 includes a first measuring body 21 and at least one second measuring body 22, the second measuring body 22 being disposed perpendicularly to the first measuring body 21, the first measuring body 21 being slidably mounted on the positioning element 1, wherein the first measuring body 21 is disposed perpendicularly to the positioning element 1, and the second measuring body 22 is disposed parallel to the positioning element 1.

[0038] For example, in some embodiments of this application, the measuring fixture 100 according to this application is used to inspect a mesh-like film attached to the back glass of a photovoltaic system, i.e., the product to be tested is a back glass with a mesh-like film attached. However, this application is not limited to this, and the measuring fixture 100 can also be applied to other products that require measurement and inspection using the measuring fixture 100.

[0039] like Figure 1 As shown, the main structure of the positioning element 1, the main structure of the first measuring body 21, and the main structure of the second measuring body 22 are all elongated strips. Furthermore, the longitudinal and transverse film strips in the mesh-like film attached to the back glass are also elongated strips.

[0040] During the inspection process, inspectors can select a reference line in the back glass and place the positioning element 1 on the back glass based on this reference line, wherein the length direction of the positioning element 1 is parallel to the reference line. It should be understood that, when the mesh-like membrane body meets the design requirements, the longitudinal or transverse membrane strips in the mesh-like membrane body are parallel to the reference line.

[0041] For example, taking the case of testing the straight line as the inspection reference line and the horizontal film strip as the horizontal film strip in accordance with the design requirements. When the positioning member 1 is placed on the back glass based on the straight line as the inspection reference line, the length direction of the positioning member 1 is parallel to the horizontal film strip in accordance with the design requirements. Since the first measuring body 21 is slidably assembled to the positioning member 1 and is perpendicular to the positioning member 1, it can also be understood that the length direction of the positioning member 1 is perpendicular to the length direction of the first measuring body 21, that is, the length direction of the first measuring body 21 is parallel to the longitudinal film strip in accordance with the design requirements. And the second measuring body 22 is vertically arranged on the first measuring body 21 and is parallel to the positioning member 1, that is, the length direction of the second measuring body 22 is parallel to the horizontal film strip in accordance with the design requirements. Therefore, during the inspection process using the measuring tool 100, the positioning member 1 and the second measuring body 22 are parallel to the horizontal film strip in accordance with the design requirements, and the first measuring body 21 is parallel to the longitudinal film strip in accordance with the design requirements.

[0042] Based on this, during the inspection process, the inspector can mark the positioning points corresponding to each longitudinal film strip in the positioning member 1 in advance according to the position and size of each longitudinal film strip in the design drawing, using a marking pen. Then the inspector moves the first measuring body 21 along the length direction of the positioning member 1 from one side to the other side. During the movement of the first measuring body 21, when the first measuring body 21 moves to the positioning point of a longitudinal film strip, the inspector observes whether the first measuring body 21 and the corresponding longitudinal film strip are coincident from the top view. It should be understood that the positioning point of each longitudinal film strip is the mark made in the positioning member 1 according to the design drawing. If the longitudinal film strip is in accordance with the design requirements, it will coincide with the corresponding positioning point. If the longitudinal film strip does not meet the design requirements, it will be offset from the corresponding positioning point. Therefore, through the measuring tool 100, it can quickly measure and test whether the longitudinal film strip meets the design requirements.

[0043] In addition, the second measuring body 22 is arranged on the first measuring body 21 according to the position and size of the horizontal film strip in the design drawing. It can also be understood that each second measuring body 22 is arranged on the first measuring body 21 according to the position relationship in the design drawing, so that each second measuring body 22 is used to measure and test whether the corresponding horizontal film strip meets the design requirements during the movement of the first measuring body 21 along the length direction of the positioning member 1. Therefore, through the measuring tool 100, it can quickly measure and test whether the horizontal film strip meets the design requirements.

[0044] In summary, the measuring tool 100 according to the present application can quickly measure and test the position and size of the longitudinal lines (such as longitudinal film strips) and the horizontal lines (such as horizontal film strips) in the grid structure to test whether the grid structure meets the design requirements. For example, through the measuring tool 100, it can measure and test whether the interval values of the adjacent two longitudinal lines and the adjacent two horizontal lines meet the design requirements.

[0045] The measurement tool 100 of the present application is used for measuring the film body with the grid structure attached to the back glass, which improves the measuring and inspecting efficiency of the inspector, reduces the labor cost, ensures the accuracy of the measurement and inspection, and effectively reduces the product defect rate. Therefore, the measurement tool 100 of the present application is used for measuring the film body with the grid structure attached to the back glass, which improves the production efficiency.

[0046] It should be noted that in some embodiments described above, the inspector marks the corresponding positioning points in the positioning member 1 according to the position size in the design drawing by using a marker, and then judges the positional relationship between the corresponding positioning points and the corresponding longitudinal film strip. However, the present application is not limited to this. As shown in FIG. 6, in some embodiments of the present application, the positioning member 1 is provided with a first scale line 51, and the first scale line 51 is arranged along the length direction of the positioning member 1. In this way, during the movement of the first measuring body 21 along the length direction of the positioning member 1, the inspector can judge the displacement amount of the first measuring body 21 according to the first scale line 51 arranged on the positioning member 1, so as to determine whether the position size of the longitudinal film strip meets the design requirement. For the positioning member 1 provided with the first scale line 51, the inspector can not need to mark the positioning points on the positioning member 1 by using the marker, and the inspector only needs to read the displacement amount for judgment, so as to further improve the efficiency. In addition, for different design size drawings, the reading of the displacement amount by the first scale line 51 can also improve the universality of the measurement tool 100. Figure 1

[0047] In some embodiments of the present application, the first measuring body 21 and the second measuring body 22 can be in a permanent fixed connection relationship, for example, the measuring member 2 is an integrally formed member, and the relative position relationship between the first measuring body 21 and the second measuring body 22 is in a permanent fixed state. However, the present application is not limited to this. In some embodiments of the present application, the second measuring body 22 is movably assembled on the first measuring body 21. It can also be understood that along the length direction of the first measuring body 21, the relative position of the second measuring body 22 and the first measuring body 21 can be adjusted, so that the spacing value of the adjacent two second measuring bodies 22 can be adjusted, so as to further improve the universality of the measurement tool 100. For example, the second measuring body 22 is slidably assembled on the first measuring body 21, or the second measuring body 22 is detachably assembled on the first measuring body 21, and the spacing value of the adjacent two second measuring bodies 22 is adjusted by changing the assembly position of the second measuring body 22.

[0048] Referring to FIG. 6, in some embodiments of the present application, the first measuring body 21 is provided with a second scale line 52, and the second scale line 52 is arranged along the length direction of the first measuring body 21. In this way, during the movement of the first measuring body 21 along the length direction of the positioning member 1, the inspector can judge the displacement amount of the first measuring body 21 according to the second scale line 52 arranged on the first measuring body 21, so as to determine whether the position size of the longitudinal film strip meets the design requirement. For the first measuring body 21 provided with the second scale line 52, the inspector can not need to mark the positioning points on the first measuring body 21 by using the marker, and the inspector only needs to read the displacement amount for judgment, so as to further improve the efficiency. In addition, for different design size drawings, the reading of the displacement amount by the second scale line 52 can also improve the universality of the measurement tool 100. Figure 1 ​In some embodiments of the present application, the first measuring body 21 is provided with a second scale 52, which is arranged along the length direction of the first measuring body 21. In this way, during the movement of the second measuring body 22 along the length direction of the first measuring body 21, the inspector can determine the displacement of the second measuring body 22 according to the second scale 52 arranged on the first measuring body 21, so as to determine whether the position size of the transverse film strip meets the design requirements. For the first measuring body 21 provided with the second scale 52, the inspector can not need to mark the positioning point on the first measuring body 21 with a marker pen, and the inspector only needs to read the displacement to determine, so as to further improve the efficiency. In addition, for different design sizes of the drawing, the way of reading the displacement through the second scale 52 can also improve the versatility of the measuring tool 100.

[0049] Referring to Figure 1 In some embodiments of the present application, the second measuring body 22 is provided with an offset observation piece 221, the cross-sectional shape of the offset observation piece 221 is an isosceles triangle, and the center line of the offset observation piece 221 coincides with the center line of the second measuring body 22. It should be understood that the cross-sectional shape of the offset observation piece 221 is an isosceles triangle, which can also be understood as that when the measuring tool 100 is observed from a top view angle, the orthographic projection shape of the offset observation piece 221 is an isosceles triangle. And the center line of the offset observation piece 221 is the center line of the base of the isosceles triangle.

[0050] For example, the measuring tool 100 is used to measure the film body attached to the back glass in a grid structure, and the second measuring body 22 is used to measure the transverse film strip in the film body in the grid structure. It should be noted that the film strip has a certain width.

[0051] If the transverse film strip attached to the back glass is offset, that is, an included angle is formed between one of the adjacent two transverse film strips and the other transverse film strip. It should be understood that in the case that the transverse film strip meets the design drawing requirements, the adjacent two transverse film strips should be arranged in parallel. In this case, the second measuring body 22 moves under the drive of the first measuring body 21, and in this process, the inspector observes the relative position relationship between the offset observation piece 221 and the transverse film strip from a top view angle, so as to determine whether the transverse film strip is offset through vision.

[0052] It needs to be understood that when the offset observation piece 221 with the isosceles triangular cross-sectional shape moves along the straight line, if the lateral film belt does not exist the offset condition, then the distance between the two waists of the isosceles triangular piece and the lateral film belt should be equal at any position, because the distance between the two parallel straight lines (i.e. the two parallel edges of the lateral film belt) is equal everywhere. If the lateral film belt exists the offset condition, then the distance between the two waists of the isosceles triangular piece and the two parallel straight lines will not be equal. Thus, by arranging the offset observation piece 221 with the isosceles triangular cross-sectional shape on the second measuring body 22, the inspector can visually judge whether the lateral film belt exists the offset condition. Based on this, the inspector can quickly judge whether the lateral film belt exists the offset condition visually, so that the inspector can judge whether the lateral film belt exists the offset condition by reading the interval value of the adjacent two lateral film belts, further improving the inspection efficiency.

[0053] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments of the present application, the positioning piece 1 includes a positioning piece body 11 and a fixing structure, the fixing structure is arranged on the positioning piece body 11, and the fixing structure is used for assembly cooperation with the product to be measured (for example, the back glass attached with the grid-shaped film body) to realize the effect of assembly positioning of the positioning piece 1 and the product to be measured. In this way, the effect of installing and fixing the measuring tool 100 on the selected inspection reference straight line based on the product to be measured can be realized, so as to limit the relative positional relationship between the positioning piece 1 and the product to be measured, and improve the accuracy of using the measuring tool 100.

[0054] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments of the present application, the fixing structure includes at least one positioning protrusion 12 and / or at least one positioning hole (not shown in the drawings). It can also be understood that the fixing structure includes at least one positioning protrusion 12, or the fixing structure includes at least one positioning hole, or the fixing structure includes at least one positioning protrusion 12 and at least one positioning hole.

[0055] For example, in some embodiments of the present application, the back glass attached with the grid-shaped film body is provided with a through hole, which can be used as a positioning cooperation hole of the back glass. Correspondingly, the fixing structure includes at least one positioning protrusion 12, and the positioning protrusion 12 is adapted to extend into the positioning hole of the back glass to realize the effect of positioning cooperation between the positioning piece 1 and the back glass, that is, the effect of positioning cooperation between the measuring tool 100 and the back glass.

[0056] In some embodiments, the back glass is provided with a plurality of positioning matching holes, and the arrangement direction of the plurality of positioning matching holes is parallel to the inspection reference straight line. The plurality of positioning protrusions 12 arranged in the positioning member 1 are arranged in sequence along the length direction of the positioning member body 11. In this way, when each positioning protrusion 12 is positioned and matched with each positioning matching hole, the length direction of the positioning member body 11 is parallel to the inspection reference straight line, that is, the length direction of the positioning member 1 is parallel to the inspection reference straight line. In addition, it is worth noting that, for example, the cross section of the positioning matching hole is circular, and the cross section of the positioning protrusion 12 is correspondingly arranged in a circular shape. In this way, the positioning member 1 is provided with a plurality of positioning protrusions 12, which can avoid the rotation of the positioning member 1 and ensure that the length direction of the positioning member 1 is parallel to the inspection reference straight line.

[0057] However, the present application is not limited thereto. In some embodiments of the present application, the cross section of the positioning matching hole can be polygonal, such as triangular, quadrilateral, pentagonal, etc. The cross section of the positioning protrusion 12 is correspondingly shaped, for example, the cross section of the positioning matching hole is triangular, and the cross section of the positioning protrusion 12 is a corresponding triangular shape. In this way, when the positioning member 1 has only one positioning protrusion 12, the positioning protrusion 12 has a tendency to rotate around the axis of the positioning protrusion 12 relative to the positioning matching hole. The peripheral wall of the positioning matching hole limits the positioning protrusion 12, preventing the positioning protrusion 12 from rotating, and ensuring that the length direction of the positioning member 1 is parallel to the inspection reference straight line. In the above-mentioned embodiments, the fixed structure is taken as an example of the positioning protrusion 12, but the present application is not limited thereto. The fixed structure can also be a positioning hole, and the structure of the positioning hole can be a through hole, a counterbore, etc. Since the fixed structure is the positioning protrusion 12 or the positioning hole that is positioned and matched with the product to be measured, further description is omitted here.

[0058] In the above-mentioned embodiments, the fixed structure includes at least one positioning protrusion 12 and / or positioning hole. However, the present application is not limited thereto. In some embodiments of the present application, the fixed structure can include at least one suction cup member, which is fixed by suction cup member adsorption to the back glass, thereby achieving the parallel state of the length direction of the positioning member 1 and the inspection reference straight line.

[0059] It should be further noted that in some embodiments, the fixing structure is movably assembled to the positioning member body 11 along the length direction of the positioning member body 11 (for example, the fixing structure is slidably assembled to the positioning member body 11), so that the position relationship of the fixing structure relative to the positioning member body 11 can be adjusted. For example, the fixing structure includes a plurality of positioning protrusions 12, at least one of the plurality of positioning protrusions 12 is slidably assembled to the positioning member body 11, and the spacing between the positioning protrusion 12 and the adjacent positioning protrusion 12 can be adjusted by sliding the positioning protrusion 12, so as to improve the versatility of the measuring tool 100. For example, the hole spacing of the positioning fitting holes in different back glasses is different, and by adjusting the position of the positioning protrusion 12 in the positioning member body 11, the positioning member 1 can be adapted to different back glasses.

[0060] In some embodiments of the present application, the measuring tool 100 includes a first sliding structure, and the positioning member 1 and the first measuring body 21 are slidably connected through the first sliding structure. Referring to Figure 1 and Figure 2 and Figure 4 In some embodiments, the first sliding structure includes a first sliding groove 31 and a first sliding block 32, the first sliding groove 31 is arranged on the positioning member 1 and extends along the length direction of the positioning member 1, and the first sliding block 32 is arranged on the first measuring body 21, so that in the assembled state of the positioning member 1 and the measuring member 2, the first sliding block 32 arranged on the first measuring body 21 is assembled into the first sliding groove 31 arranged on the positioning member 1, and the first sliding block 32 is adapted to slide along the first sliding groove 31, thereby achieving the effect that the measuring member 2 slides along the length direction of the positioning member 1.

[0061] Alternatively, referring to Figure 3 In other embodiments, the first sliding structure is configured as a first sliding block member 4, the first sliding block member 4 is provided with a first sliding groove 40 adapted to be slidably connected with part of the positioning member 1, so that the first sliding block member 4 is configured to slide along the length direction of the positioning member 1, and the first measuring body 21 is arranged on the first sliding block member 4. In this way, the measuring member 2 and the positioning member 1 are relatively moved through the first sliding block member 4, that is, the effect that the measuring member 2 slides along the length direction of the positioning member 1 is achieved.

[0062] Referring to Figures 1 to 4As shown, in some embodiments of the present application, the measuring member 2 can further comprise a first locking member 23, which is assembled to the first measuring body 21 and is adapted to abut against the positioning member 1. By abutting the first locking member 23 against the positioning member 1, the relative position of the first measuring body 21 and the positioning member 1 is fixed, which achieves the effect of locking the first measuring body 21 to the positioning member 1, so that the first measuring body 21 can be prevented from moving relative to the positioning member 1 during the use of the measuring tool 100.

[0063] As shown, for example, Figure 1 and Figure 4 The first locking member 23 can be configured as a screw structure, and the first measuring body 21 is provided with a through hole with internal threads, so that the first locking member 23 can be screw-assembled to the first measuring body 21, and the first locking member 23 also penetrates the first measuring body 21, so that the first locking member 23 is adapted to abut against the positioning member 1. When the first locking member 23 is in contact with the positioning member 1, the frictional force generated by the first locking member 23 and the positioning member 1 can limit the movement of the first measuring body 21 relative to the positioning member 1.

[0064] In some embodiments of the present application, the second measuring body 22 is movably assembled to the first measuring body 21 along the length direction of the first measuring body 21. For example, in some embodiments, the first measuring body 21 is provided with a plurality of positioning assembly portions arranged along the length direction of the first measuring body 21, and the second measuring body 22 is provided with a positioning matching portion which is assembled and matched with the positioning assembly portions. Alternatively, in some other embodiments, the measuring member 2 is provided with a second sliding structure, and the first measuring body 21 and the second measuring body 22 are slidingly matched through the second sliding structure.

[0065] Exemplarily, in some embodiments, a plurality of positioning assembly portions are arranged along the length direction of the first measuring body 21, and each positioning assembly portion of the second measuring body 22 is adapted to be assembled with any one of the plurality of positioning assembly portions, so that the single second measuring body 22 is optionally assembled with one of the plurality of positioning assembly portions, thereby achieving the effect that the second measuring body 22 is movably assembled with the first measuring body 21. For example, the positioning assembly portion is configured as a threaded hole, the positioning assembly portion is configured as a threaded rod, and the threaded rod is screwed with the threaded hole, thereby achieving the effect that the second measuring body 22 is detachably assembled with the first measuring body 21. Alternatively, the positioning assembly portion is configured as one of a clamping recess and a clamping protrusion, the positioning assembly portion is configured as the other one of the clamping recess and the clamping protrusion, and the clamping recess is clamped with the clamping protrusion, thereby achieving the effect that the second measuring body 22 is detachably assembled with the first measuring body 21.
