Description

Technical Field

[0001] This utility model relates to the field of tempered glass measurement technology, and in particular to a measuring fixture. Background Technology

[0002] The tempered glass used in photovoltaic modules requires regular fragment particle size testing. Currently, the testing procedure for tempered glass fragment particle size in photovoltaic modules is as follows: The tempered glass is laid flat, and the edges are secured with transparent tape or other methods to prevent glass fragments from scattering. At the center of the long edge, a small hammer or drill bit with a radius of curvature of 0.2mm ± 0.05mm is used to impact the glass, causing it to break. When counting fragments, the area within a radius of 80mm from the impact point and 25mm from the edge of the glass or drill hole is selected as the sparsest area after the entire tempered glass breaks. A 50mm x 50mm counting frame is used to count the number of fragments within this area. Each fragment must not have a through crack. Fragments crossing the edge of the counting frame are counted as half a fragment. However, the existing fragment counting method involves manually selecting the sparsest area, manually drawing a 50mm x 50mm square area, manually counting the fragments, and then measuring the length of long strip fragments with a steel ruler. This process is time-consuming and inefficient. Utility Model Content

[0003] Therefore, it is necessary to provide a measuring fixture to address the problems of long measurement time and low work efficiency in existing fragment counting methods.

[0004] The technical solution is as follows:

[0005] On one hand, a measuring fixture is provided for detecting the particle size of tempered glass fragments. The measuring fixture includes a fixture body with a frame-selection counting hole and a measuring element disposed on the fixture body. The frame-selection counting hole is used to select a corresponding counting area within the selected range of the tempered glass, so as to calculate the number of glass fragments within the counting area. The measuring element is used to measure the length of the tempered glass fragments.

[0006] In the above embodiments, the measuring fixture is used by attaching the fixture body to the broken tempered glass and selecting a corresponding counting area within the tempered glass using the frame-selection counting holes, so as to calculate the number of glass fragments within the counting area. When the counting area has been counted and the length of a long strip of glass fragment needs to be measured, the fixture body can be moved directly and the measuring parts on the fixture body can be used to measure it. The measuring fixture in this application has both the functions of selecting the counting area and measuring length. It eliminates the need for manually drawing the counting area and the need for length measuring tools such as steel rulers. The selection of the counting area is highly accurate, the operation is simple and convenient, it is highly practical, and the measurement time is short, thus improving the efficiency of tempered glass fragment particle size measurement.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the tooling body includes a first frame, a second frame, a third frame, and a fourth frame. The first frame, the second frame, the third frame, and the fourth frame are connected in sequence to surround and form the frame selection counting hole. An extension is provided on the side of the first frame away from the frame selection counting hole. The extension cooperates with the first frame to form a mounting structure. The measuring element is disposed on the mounting structure.

[0009] In one embodiment, the extension direction of the first frame is perpendicular to the extension direction of the extension portion.

[0010] In one embodiment, the distance between the extension and the side of the first frame that is away from each other is set to 80 mm.

[0011] In one embodiment, along the extending direction of the extension, the projection area of ​​the extension is located within the projection area of ​​the framed counting hole.

[0012] In one embodiment, the measuring element is configured as a scale mark set along the extension direction of the extension.

[0013] In one embodiment, the widths of the first border, the second border, the third border, and the fourth border are the same and are all set to 25mm.

[0014] In one embodiment, the cross-section of the selected counting hole along the direction perpendicular to its own axis is a 50mm*50mm square.

[0015] In one embodiment, the thickness of the tooling body is set to 3 mm. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] like Figure 1 As shown, in one embodiment, a measuring fixture 10 is provided for detecting the particle size of tempered glass fragments. The measuring fixture 10 includes a fixture body 100 with a frame-selection counting hole 110 and a measuring element 200 disposed on the fixture body 100. The frame-selection counting hole 110 is used to select a corresponding counting area within the selected range of the tempered glass, so as to calculate the number of glass fragments within the counting area. The measuring element 200 is used to measure the length of the tempered glass fragments.

[0023] In the above embodiment, the measuring fixture 10 is used by attaching the fixture body 100 to the broken tempered glass and using the frame selection counting hole 110 to select the corresponding counting area within the selected range of the tempered glass, so as to calculate the number of glass fragments within the counting area. When the counting area has been counted and the length of a long strip of glass fragment needs to be measured, the fixture body 100 can be moved directly and the measuring element 200 on the fixture body 100 can be used to measure it. The measuring fixture 10 in this application has both the functions of selecting the counting area and measuring length. It eliminates the need for manually drawing the counting area and the need for length measuring tools such as steel rulers. The selection of the counting area is highly accurate, the operation is simple and convenient, it is highly practical, and the measurement time is short, thus improving the efficiency of tempered glass fragment particle size measurement.

[0024] Specifically, in this embodiment, the selection counting hole 110 has a cross-section of 50mm*50mm along the direction perpendicular to its own axis. The axial direction of the selection counting hole 110 is the same as the thickness direction of the tooling body 100.

[0025] In this specific embodiment, the fixture body 100 is set as a transparent plate (for example, a transparent plate made of acrylic material). In this way, the fixture body 100 is transparent, which facilitates visual operation and improves the practicality of the measuring fixture 10.

[0026] The thickness of the tooling body 100 can be flexibly adjusted according to actual usage needs. For example, the thickness of the tooling body 100 can be set from 2mm to 5mm. Specifically, in this embodiment, the thickness of the tooling body 100 is set to 3mm.

[0027] like Figure 1 As shown, optionally, the fixture body 100 includes a first frame 120, a second frame 130, a third frame 140, and a fourth frame 150. The first frame 120, second frame 130, third frame 140, and fourth frame 150 are connected sequentially to enclose and form a frame selection counting hole 110. An extension 160 is provided on the side of the first frame 120 away from the frame selection counting hole 110. The extension 160 cooperates with the first frame 120 to form a mounting structure, and the measuring element 200 is disposed on the mounting structure. In this way, the first frame 120, second frame 130, third frame 140, and fourth frame 150 can cooperate to form the frame selection counting hole 110 to select and count the area, while the first frame 120, extension 160, and measuring element 200 can cooperate to form a measuring tool to measure the length of glass fragments, improving the practicality of the measuring fixture 10.

[0028] In other embodiments, the measuring element 200 may also be directly disposed on any one of the first border 120, the second border 130, the third border 140, and the fourth border 150.

[0029] like Figure 1 As shown, in one embodiment, the extending direction of the first frame 120 and the extending direction of the extension 160 are perpendicular. This facilitates the measuring fixture 10 in measuring the length of the glass fragments.

[0030] In this embodiment, the extension 160 is elongated. In other embodiments, the extension 160 may be shaped in other ways. The extension direction of the first frame 120 and the extension direction of the extension 160 may also be at an angle.

[0031] like Figure 1 As shown, optionally, the distance between the extension 160 and the side of the first frame 120 that is far from each other is set to 80mm. In this way, the mounting structure can be used as a measuring tool to measure the non-counting area with a radius of 80mm from the impact point on the broken tempered glass, thereby improving the practicality and accuracy of the measuring fixture 10.

[0032] like Figure 1 As shown, optionally, along the extending direction of the extension 160, the projection area of ​​the extension 160 is located within the projection area of ​​the selected counting hole 110. This facilitates precise control of the distance between the extension 160 and the side of the first frame 120 that is far apart from each other, ensuring the accuracy of the mounting structure when measuring non-counting areas and improving the practicality of the measuring fixture 10.

[0033] The width of the extension 160 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the width of the extension 160 can be set to 20mm. The first frame 120, the second frame 130, the third frame 140, the fourth frame 150, and the extension 160 can be integrally formed. The thicknesses of the first frame 120, the second frame 130, the third frame 140, the fourth frame 150, and the extension 160 are all the same.

[0034] like Figure 1 As shown, optionally, the measuring element 200 is configured as a scale mark 210 provided along the extension direction of the extension 160.

[0035] Specifically, in this embodiment, the scale markings 210 are directly printed on the mounting structure. The scale markings 210 include a 0mm scale line corresponding to the side of the extension 160 away from the first frame 120, and an 80mm scale line corresponding to the side of the first frame 120 away from the extension 160. The scale markings 210 also include other numerical scale lines, with a spacing of 5mm between adjacent scale lines.

[0036] It should be noted that the scale markings 210 will wear down over time. Regular calibration and comparison of the scale markings 210 can ensure their effectiveness. The spacing between adjacent scale lines can be flexibly adjusted according to actual usage needs.

[0037] In other embodiments, the measuring element 200 may also be configured as a graduated film or a graduated ruler with markings. The measuring element 200 may be mounted on the mounting structure by adhesive, insertion, snap-fit, or other fixing methods.

[0038] like Figure 1 As shown, in one embodiment, the width of the first border 120, the width of the second border 130, and the width of the third border 140 (as shown) Figure 1 The width of the first frame 120 (shown in section A) and the width of the fourth frame 150 are the same, and both are set to 25mm. Thus, any one of the first frame 120, the second frame 130, the third frame 140, and the fourth frame 150 can be used as a measuring tool to measure the non-counting area within 25mm of the edge of the glass or the edge of the drill hole on the broken tempered glass, thereby improving the practicality and accuracy of the measuring fixture 10.

[0039] Specifically, in this embodiment, adjacent pairs of the first border 120, second border 130, third border 140, and fourth border 150 are connected by a connecting part. The connecting part can be a right-angle structure or an arc structure.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
