Description

Technical Field

[0001] This utility model belongs to the field of glass testing technology, and in particular relates to testing fixtures and glass production lines. Background Technology

[0002] In the glass manufacturing process, the shape accuracy of cut glass needs to be rigorously inspected to ensure it meets design specifications. Currently, for scenarios with relatively simple shapes and where there is no need for significant investment in automated inspection equipment, the most common method is to use a template for comparison. That is, a physical template with a corresponding outline is created based on the design shape of the target workpiece. Operators compare the cut glass workpiece with the physical template, and determine whether the workpiece is qualified by observing whether the outlines match.

[0003] However, this traditional template inspection method has significant drawbacks. When the production line needs to process glass workpieces of various shapes, each shape requires a dedicated inspection template, resulting in a large number of templates. Operators must search, retrieve, and replace these templates among numerous others when inspecting different workpieces. After inspection, the templates must be categorized and stored. This entire process is cumbersome and time-consuming, severely limiting inspection efficiency and making it difficult to adapt to rapid production changes. Secondly, the large number of templates requires substantial storage space, increasing the difficulty of managing the inspection tools. Utility Model Content

[0028] Please see Figures 1 to 3This application provides a testing fixture for detecting the shape of a first workpiece and a second workpiece. The testing fixture includes a first testing platform 10, which carries the first workpiece. The first testing platform 10 has a ring-shaped structure and surrounds a receiving cavity 200. The outer contour shape of the projection of the first testing platform 10 along the vertical direction is a first preset shape. The first testing platform 10 is used to detect whether the first workpiece has the first preset shape. The fixture also includes a second testing platform 20, which carries the second workpiece. The second testing platform 20 is located in the receiving cavity 200 and connected to the first testing platform 10. The outer contour shape of the projection of the second testing platform 20 along the vertical direction is a second preset shape. The second testing platform 20 is used to detect whether the second workpiece has the second preset shape.

[0029] It is understood that the first and second workpieces in the embodiments of this application can be glass, but the first and second workpieces have a first preset shape and a second preset shape, respectively, and the first and second preset shapes are different shapes. During the glass manufacturing process, the shape of the glass needs to be inspected after cutting to confirm the dimensional accuracy of the cut glass and ensure that it meets the design specifications. Of course, in other possible implementations, the target workpiece can also be other structures with specific shapes; this application does not limit the specific structure of the target workpiece.

[0030] In this embodiment, the outer contour shape of the first detection stage 10 is a first preset shape, that is, the outer contour shape of the projection of the first detection stage 10 along the vertical direction is a first preset shape, such as a rectangle, a square, a circle, an ellipse, or a triangle. The outer contour shape of the second detection stage 20 is a second preset shape, that is, the outer contour shape of the projection of the second detection stage 20 along the vertical direction is a second preset shape, such as a rectangle, a square, a circle, an ellipse, or a triangle.

[0031] In this embodiment, when inspecting a first workpiece with a first preset shape, the first workpiece is placed on a first inspection table 10, which also has a first preset shape. The outer contour line of the first workpiece is compared with the outer contour line of the first inspection table 10. The shape of the first workpiece is determined to be qualified by observing whether the two contours match. Similarly, when inspecting a second workpiece with a second preset shape, the second workpiece is placed on a first inspection table 10, which also has a second preset shape. The outer contour line of the second workpiece is compared with the outer contour line of the second inspection table 20. The shape of the second workpiece is determined to be qualified by observing whether the two contours match.

[0032] The inspection fixture provided in this application embodiment, by setting a first inspection stage 10 and a second inspection stage 20, enables it to inspect two different shaped target workpieces respectively. Furthermore, the first inspection stage 10 and the second inspection stage 20 are integrated on the same fixture, so there is no need to change the corresponding inspection tool according to the different shapes of the workpieces during inspection, thereby simplifying the inspection process and improving inspection efficiency. In addition, the second inspection stage 20 is placed in the accommodating cavity 200 formed by the first inspection stage 10, making full use of the internal space of the first inspection stage 10, thereby reducing the space occupied by the inspection fixture.

[0033] In some embodiments, such as Figure 2 As shown, the first testing station 10 includes two first support walls 11 spaced apart and a second support wall 12 connected between the two first support walls 11. Two second support walls 12 are arranged at intervals. The two first support walls 11 and the two second support walls 12 together form a receiving cavity 200. The second testing station 20 is connected to the first support walls 11 and the second support walls 12.

[0034] By connecting the second testing platform 20 to both the first support wall 11 and the second support wall 12, this configuration eliminates the rotational or offset degrees of freedom that might occur when the second testing platform 20 is supported by only one side wall, ensuring that it has a unique and precise relative position, thereby improving the stability and reliability of the testing. Furthermore, the frame structure formed by the first support wall 11 and the second support wall 12 provides a clear benchmark for the manufacturing of the testing fixture. During manufacturing, the first testing platform 10, serving as the foundation, can be precisely machined first. Then, using the inner sides of the first support wall 11 and the second support wall 12 as benchmarks, the second testing platform 20 can be positioned and machined. This helps ensure the relative positional accuracy between the two testing platforms in the manufacturing process and reduces the overall manufacturing difficulty of the fixture.

[0035] Optionally, the first support wall 11 and the second support wall 12 are perpendicular to each other, that is, the first preset shape is a rectangular structure. Understandably, most glass workpieces on the market are rectangular or contain right angles. Therefore, setting the first support wall 11 and the second support wall 12 to be perpendicular to each other accurately covers the widest range of application scenarios, can detect the shape accuracy of rectangular glass workpieces, and is highly consistent with actual production.

[0036] In addition, the key precision of rectangular glass workpieces lies not only in the side length, but also in the accuracy of their right angles and the consistency of their diagonals. When the right angles of the glass workpiece are not precise, it cannot perfectly fit with the two perpendicular first support walls 11 and second support walls 12 at the same time. Therefore, by setting the first support wall 11 and the second support wall 12 to be perpendicular to each other, the perpendicularity error generated by the workpiece during the cutting or grinding process can be directly exposed, thereby further improving the accuracy of the inspection.

[0037] In some embodiments, the first support wall 11 is provided with a first scale line 13, and multiple first scale lines 13 are arranged at intervals along the extension direction of the first support wall 11; the second support wall 12 is provided with a second scale line 14, and multiple second scale lines 14 are arranged at intervals along the extension direction of the second support wall 12. It can be understood that by providing the first scale line 13 and the second scale line 14 on the first support wall 11 and the second support wall 12 respectively, the first detection stage 10 is no longer limited to detecting only target workpieces of a first preset shape. For example, when the first preset shape is a square, and the first workpiece to be detected is a rectangle, and the long side of the first workpiece to be detected is equal to the side length of the first preset shape, and the wide side of the first workpiece to be detected is less than the side length of the first preset shape, then one of the long sides of the first workpiece to be detected can be aligned with the edge of the first detection stage 10, and the other long side of the first workpiece to be detected can be compared with a certain scale line, thus confirming the dimensional accuracy of the first workpiece.

[0038] Understandably, by setting the first scale line 13 and the second scale line 14, the inspection fixture can not only determine whether the shape of the first workpiece is qualified, but also perform quantitative inspection based on the first scale line 13 and the second scale line 14. While using the fixture for comparison, the operator can directly obtain key dimensions such as the length or width of the first workpiece by reading the first scale line 13 or the second scale line 14, thereby improving the comprehensiveness of the inspection.

[0039] In some embodiments, the first detection stage 10 further includes a first connecting wall 15 and a second connecting wall 16. One end of the first connecting wall 15 is connected to the first support wall 11, and the other end of the first connecting wall 15 is connected to the side wall of the second detection stage 20. One end of the second connecting wall 16 is connected to the second support wall 12, and the other end of the second connecting wall 16 is connected to the side wall of the second detection stage 20. The heights of the first connecting wall 15, the second connecting wall 16, the first support wall 11, the second support wall 12, and the second detection stage 20 are equal.

[0040] By setting the first connecting wall 15 and the second connecting wall 16, the first connecting wall 15, the second connecting wall 16, the first support wall 11, the second support wall 12, and the second testing table 20 together form an integral structure, which can enhance the overall structural rigidity of the testing fixture, thereby more effectively resisting bending and torsional deformation, ensuring that the entire testing reference plane will not collapse or warp under long-term use and load, thus guaranteeing the long-term accuracy life of the testing fixture.

[0041] In addition, the heights of the first connecting wall 15, the second connecting wall 16, the first supporting wall 11, the second supporting wall 12, and the second testing platform 20 are equal, meaning that the top surfaces of the first connecting wall 15, the second connecting wall 16, the first supporting wall 11, the second supporting wall 12, and the second testing platform 20 are at the same horizontal height. This together forms a continuous, flat, and stepless testing reference plane, eliminating the problems of workpiece tilting, shaking, or needing to be re-leveled due to uneven testing platform heights. This ensures the consistency of workpiece condition and guarantees the accuracy and comparability of the testing results.

[0042] In some embodiments, the testing fixture further includes a positioning structure 30, which is connected to the first support wall 11 or the second support wall 12. The positioning structure 30 is used to position the first workpiece. By setting the positioning structure 30, the first workpiece to be tested can be initially positioned, ensuring that each target workpiece being tested is placed in the exact same position, ensuring the consistency of the testing state, and guaranteeing the comparability and reliability of the results.

[0043] In some embodiments, the positioning structure 30 includes a first positioning block 31 and a second positioning block 32, which are respectively connected to the first support wall 11 and the second support wall 12. The first positioning block 31 and the second positioning block 32 are respectively used to abut against the adjacent two sides of the first workpiece to position the first workpiece. In this embodiment, the first positioning block 31 and the second positioning block 32 abut against the adjacent two sides of the first workpiece. The operator only needs to move the first workpiece towards these two positioning blocks simultaneously to complete the precise positioning in two vertical directions. The positioning speed is extremely fast, and the positioning state is unique and repeatable, laying the foundation for subsequent shape comparison.

[0044] In this embodiment, after the first workpiece is positioned by the first positioning block 31 and the second positioning block 32, it can be compared whether the diagonal of the first workpiece is consistent with the diagonal of the first detection table 10. Optionally, multiple first positioning blocks 31 and multiple second positioning blocks 32 are arranged at intervals, thereby further improving the positioning effect on the target workpiece.

[0045] In some embodiments, the inspection fixture further includes a base plate 40, with the first inspection table 10 and the second inspection table 20 connected to one side of the base plate 40. By setting the base plate 40 as a rigid support platform, a common and stable mounting reference is provided for the first inspection table 10 and the second inspection table 20. The first inspection table 10 and the second inspection table 20 are connected to the same base plate 40, forming a robust integral structure. This greatly enhances the overall rigidity of the inspection fixture, effectively resisting torsional or bending deformation that may occur during use and handling, ensuring that the relative positional relationship of the first inspection table 10 and the second inspection table 20, as well as their own shape accuracy, remain stable over a long period. Furthermore, by setting the base plate 40, the inspection fixture can be stably placed on any workbench, assembly line, or rack without wobbling due to local unevenness. Simultaneously, mounting holes or positioning pin holes can be pre-set on the base plate 40, facilitating the use of bolts to firmly fix the inspection fixture to a specific workstation, preventing displacement during operation, and also facilitating rapid positioning and installation on automated production lines.

[0046] In some embodiments, the first preset shape is a rectangle and the second preset shape is a circle. Of course, in other possible embodiments, the first preset shape and the second preset shape can also be other shapes, and the specific shapes of the first preset shape and the second preset shape are not uniquely limited in the embodiments of this application.

[0047] Optionally, such as Figure 3 As shown, multiple second inspection stations 20 can be arranged at intervals, and all multiple second inspection stations 20 are located within the receiving cavity 200, thereby enabling the inspection of multiple second workpieces and further improving testing efficiency. Optionally, the second inspection station 20 can also be a ring structure, thereby saving materials.

[0048] This utility model also proposes a glass production line, which includes a testing fixture. The specific structure of the testing fixture is as described in the above embodiments. Since this glass production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] In summary, the inspection fixture provided in this application embodiment, by setting a first inspection table 10 and a second inspection table 20, enables it to inspect two different shapes of workpieces respectively. Furthermore, the first inspection table 10 and the second inspection table 20 are integrated on the same fixture, so there is no need to change the corresponding inspection tool according to the different shapes of the target workpieces during inspection, thereby simplifying the inspection process and improving inspection efficiency. In addition, the second inspection table 20 is placed in the accommodating cavity 200 formed by the first inspection table 10, making full use of the internal space of the first inspection table 10, thereby reducing the space occupied by the inspection fixture.
