Technical Field

The invention relates to the field of glass quality detection, in particular to a glass profile detection device.

Background

The method is generally used for manually detecting whether the camber of the glass profile is qualified. The specific detection method is as follows: and placing the glass to be detected on a standard plane, and detecting the designated position of the inner surface of the glass to be detected. The measuring method is characterized in that the distance between the inner surface of the glass to be measured and the standard plane is manually measured, and the distance is compared with a design value to judge whether the camber of the position is qualified. Because the measuring mode has no standard coordinate system, when the measuring point is manually selected, the measured position is difficult to be ensured to be the appointed measuring position, reading errors and operation errors in the measuring process exist, and effective evasive means does not exist, so that the measuring result can hardly reflect the real situation.

Therefore, it is urgently needed to provide a measuring device with a standard coordinate system, which can accurately locate each point to be detected on the device, can conveniently and effectively measure the detection points, and further judge whether the camber of the glass molded surface is qualified by measuring whether the camber of each detection point is qualified.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless otherwise specified, the terms "upper, lower, left, right, top, bottom", and the like included in the terms represent only the orientation of the terms in a conventional use state or are colloquially known by those skilled in the art, and should not be construed as limiting the terms.

Referring to fig. 1, the glass profile testing device comprises a base 2 and a plurality of testing mechanisms 1 which are detachably mounted on the base 2, wherein each testing mechanism 1 is provided with a plurality of testing points, an inner contour line 11 of each testing mechanism 1 is a measuring reference, and the radian of the inner contour line is consistent with that of the outer surface of a standard glass profile at the position;

the base 2 is a checking fixture matched with the detection mechanism 1.

Through the implementation of the technical scheme, the base 2 is calibrated by the three-coordinate measuring machine and used as a reference surface of the glass profile detection device. The plane determined by the base 2 is used as the xoy plane, each point on the standard glass molded surface has a coordinate, namely any point (x, y) on the xoy plane in the standard glass molded surface corresponds to a height coordinate z, and therefore, whether the curvature of the glass 3 to be detected is qualified or not can be detected by measuring the height coordinate z of the glass 3 to be detected at the (x, y) coordinate point^，And a is^，And then checking whether the comparison result meets the requirement of design tolerance or not to judge whether the camber of the point is qualified or not.

If the curvature of the molded surface of the glass to be detected is qualified, enough detection points are selected, whether the curvature of the detection points is qualified or not is detected, and after the detection results of all the detection points are summarized, the evaluation on whether the molded surface of the glass 3 to be detected is qualified or not is formed.

As shown in FIG. 5, first, the center point of the glass profile is selected as the first detection position, and the coordinates (X) of the center point in the xoy plane are determined₀，Y₀) For reference, a plane parallel to the yoz plane passing through the point intersects with the standard glass profile, and a curve obtained by the intersection is a standard curve of the position, and the inner contour line of the detection mechanism 1 is made according to the standard curve. And the first point to be measured, i.e. the center point (X), is marked on the detection mechanism 1₀，Y₀) The corresponding position is a first detection point. The other detection points on the detection means 1 can be obtained in pairs by extending the first detection point at equal distances along the detection means 1. Preferably, a set of detection points is determined at a distance of 100mm from each end of the detection mechanism 1, so that the distribution of the detection points is more discrete and the data is more representative.

Preferably, with the detecting means 1 passing through the center point of the glass profile as a reference, moving towards both sides with equal distance along the direction of the X axis, another 2 detecting means 1 will be selected, usually at 100mm from each of the two end edges of the glass profile, first taking their respective middle position as their first detecting point, and then with this first detecting point as a reference, determining the other detecting points on the two detecting means 1 respectively according to the method of taking the other detecting points on the detecting means 1 as described above.

By carrying out the above steps, the glass profile inspection device has obtained at least 3 inspection devices 1 and a total of at least 9 inspection points on these inspection devices, and if more inspection points are desired, the inspection devices 1 and the inspection points on the inspection devices can be added symmetrically according to the above steps.

The base 2 is a checking fixture calibrated by three coordinates, and the glass 3 to be detected is fixed by the positioning device 21 after being placed on the base 2, so that the position of the glass 3 to be detected on the base can be ensured to be a set position. The supporting position 22 on the base 2 is also calibrated by three coordinates, so as to ensure that the detection point on the detection mechanism 1 is the designed detection point after the detection mechanism 1 is installed in place.

As shown in fig. 3, the supporting position 22 on the base 2 has a supporting bolt 221, the detecting mechanism 1 has a U-shaped hole 12 matched with the supporting bolt 221, when the glass to be detected needs to be detected, the glass to be detected is put on the base 2, the positioning device 21 acts to fix the glass 3 to be detected, and then the U-shaped hole 12 of the detecting mechanism 1 is clamped on the supporting bolt 221. The positioning of the glass to be inspected and the inspection device 1 has now been completed so that the components of the glass profile inspection device are in the design position.

As shown in fig. 6, when the curvature of the molded surface of the glass 3 to be detected is qualified, the detection structure 1 is placed on the glass 3 to be detected, the clearance between the glass 3 to be detected and the detection mechanism 1 at the detection position is measured by a feeler gauge, and the curvature of the detection point can be judged to be qualified by comparing the value with theoretical data. When the feeler is used to measure the distance between the glass 3 to be measured and the detecting mechanism 1, the measurement error is usually small, so that the operation is simple and effective.

As shown in fig. 2, the inner contour line of the detecting unit 1 is a curve obtained by intersecting the plane of the detecting unit 1 with the outer surface of the standard glass mold surface. Therefore, the actual distance between the outer surface of the glass to be measured and the inner contour line 1 of the detection mechanism 1 is measured by taking the inner contour line 11 of the detection mechanism 1 as a measurement reference, the actually measured value is compared with the tolerance range of the design requirement, if the tolerance requirement is met, the camber of the detection point is qualified, and if the measured value cannot meet the tolerance requirement, the camber of the detection point is unqualified.

In this embodiment, there is preferably a standard inspection gap between the inner contour line 11 and the outer surface of the profile of the glass 3 to be inspected. Due to the influence of design tolerance and manufacturing error, if the installation height of the detection mechanism 1 is the design height of the glass profile at the position, the glass 3 to be detected may interfere with the detection mechanism 1, and therefore, the installation height of the detection mechanism 1 needs to be translated upwards by a certain displacement along the Z-axis from the design position, so as to ensure that the glass profile detection device has better compatibility. The effect of this translational displacement on the measurement is: the inner contour line 11 has a clearance with the outer surface of the standard glass profile and this clearance is equal to the translational displacement of the inspection mechanism 1 in relation to the position of the standard glass profile, which we call the standard inspection clearance. In this case, the actual measurement result and the design value are compared while considering the influence of the standard measurement gap, and in order to facilitate the operation of quality control personnel, the glass profile detection device may be provided with a measurement result comparison file, in which the qualified range of the measurement value of each detection point is marked, if the measured actual value is within the range marked by the file, the curvature of the glass 3 to be measured at the detection point is qualified, and if the measurement value exceeds the qualified range marked by the file, the curvature of the glass 3 to be measured at the detection point is unqualified.

In this embodiment, the base 2 is preferably provided with positioning means 21. The base 2 is a three-coordinate calibrated checking fixture and can be used as a reference datum in the measurement process of the glass profile detection device, so that in order to ensure that the measurement data of the glass profile detection device is accurate, the glass 3 to be measured has a relatively fixed and accurate fixed position on the base 2, which is realized by the positioning device 21 on the base 2. Carry out the spacing of Y direction by placing point 23 to glass 3 that awaits measuring on base 2, glass 3 that awaits measuring leans on and places on base 2 at placing point 23, has just so realized the location of glass 3 that awaits measuring in the Y direction, then, positioner 21's fastener action, and glass 3 that awaits measuring is also fixed in the position of X direction, has just so guaranteed glass 3 that awaits measuring at base 2's relatively fixed and accurate fixed position.

In this embodiment, preferably, a pair of support positions 22 is provided at corresponding positions of both ends of each detection mechanism 1, and the support positions 22 are fixed on the base 2. The fixed and exact fixing of the detection means 1 on the base 2 is ensured by the support 22. Since the supporting positions 22 are located on the base 2 and calibrated by three coordinates, the position of the detecting mechanism 1 on the base 2 is a fixed and accurate position after the two ends of the detecting mechanism 1 are fixed on the two supporting positions 22. All detection points on the detection mechanism 1 are now already in their design position.

As shown in fig. 4, in this embodiment, the fixing positions of the detecting mechanisms 1 are preferably uniformly distributed on the base 2, and the detecting mechanisms 1 of the center line position of the profile to be detected are taken as the symmetry axes. As the plane selected by the detection mechanism 1 firstly is a plane parallel to the yoz plane and the central point of the glass molded surface is located, the curve of the plane intersected with the outer surface of the glass molded surface is the inner contour line of the detection mechanism 1. Then, the other set of detecting means 1 is obtained by moving the detecting means 1 in the X-axis direction at equal distances on both sides. Therefore, the rest of the detection mechanisms 1 are symmetrically distributed about the detection mechanism 1 passing through the central point, and the glass molded surface is also a curved surface symmetrical about the central line of the glass molded surface, so that the data of the detection points can be used for judging whether the curvature of the glass 3 to be detected is qualified or not, and the bilateral symmetry condition of the glass 3 to be detected can also be judged by comparing the measurement data of the mutually symmetrical detection points.

In this embodiment, it is preferable that the detection mechanisms 1 at different positions mark different detection position numbers. Since each detection mechanism 1 corresponds to a respective designed detection point, their positions on the base 2 are fixed and cannot be mixed. Therefore, the number can be made on the body of the detection mechanism 1, and the support position 22 can also be correspondingly marked corresponding to the number of the detection mechanism 1. So that the operator can quickly recognize the installation position of the detection mechanism.
