Description

Technical Field

[0001] The present invention relates to the field of measurement and positioning technology, and more specifically, to a glass size measurement and positioning device. Background Art

[0002] After the glass is produced, its edges are often very sharp, which can easily scratch people or cause other safety hazards when used. The edge grinding machine can be used to grind and polish the glass edge to make the glass edge smooth, thereby greatly reducing the risk of scratches. Glass edge grinding machine is one of the most widely used mechanical equipment in glass deep processing equipment, mainly used for the processing of furniture glass, architectural glass and craft glass. Some existing glass edge grinding machines require manual loading when loading, which has low loading efficiency, high labor intensity, and is prone to glass breakage or safety accidents caused by manual negligence. Some edge grinding machines use measuring and positioning devices for measurement and positioning when loading, but because the edge grinding process takes a long time, while the measurement and positioning process takes a relatively short time, a measuring and positioning device is used with an edge grinding machine, resulting in the measuring and positioning device being idle for a long time. This long idle state significantly reduces the resource utilization of the equipment. In addition, the measuring and positioning device needs to be calibrated after long-term use, and the existing measuring and positioning device cannot achieve automatic calibration. Measurement deviations or error accumulation may not be discovered in time, which may lead to a decline in product quality or problems in the production process cannot be discovered and solved in time.

[0046] The present application also discloses a measurement and positioning method based on the above-mentioned glass size measurement and positioning device, comprising the following steps:

[0047] 1) The glass 9 is transported by the first transport unit. When the proximity switch 6.8.1 senses the glass 9, the upper frame 6 is raised by the first electric lift rod 1.1, and the glass 9 is fixed by the vacuum suction cup unit 5.5. The size of the glass 9 is detected by the four first detection parts;

[0048] 2) Next, the glass 9 is rotated 90 degrees using the vacuum suction cup unit 5.5, and the size of the glass 9 is detected using the four first detection units;

[0049] 3) The lower frame 5 descends, and the glass 9 is transported to the top of the lifting and transporting unit by the first transporting unit and the second transporting unit;

[0050] 4) When the difference between the data detected by the two first detection parts of the first inverted U-shaped frame in step 1) and the data detected by the two first detection parts of the second inverted U-shaped frame is greater than or equal to the set threshold, or the difference between the data detected by the two first detection parts of the first inverted U-shaped frame in step 2) and the data detected by the two first detection parts of the second inverted U-shaped frame is greater than or equal to the set threshold, the glass 9 is pushed to the lifting plate 8.3 by using the conveyor belt unit and the push plate 7.8;

[0051] When the difference between the data detected by the two first detection parts of the first inverted U-shaped frame in step 1) and the data detected by the two first detection parts of the second inverted U-shaped frame is less than the set threshold, and the difference between the data detected by the two first detection parts of the first inverted U-shaped frame in step 2) and the data detected by the two first detection parts of the second inverted U-shaped frame is less than the set threshold; the lower frame, the lifting frame and the detection frame rise, and the size of the glass 9 is detected by the lifting wheel 5.6 and the second detection part, and the first wheel 1.4 or the second wheel 1.5. When the difference between the detection data and the two data detected in step 2) is less than the set threshold, the lifting frame descends, and the second conveying unit is used to continue to convey the glass downstream; when the difference between the detection data and one or more of the two data detected in step 2) is greater than or equal to the set threshold, the conveyor belt unit and the push plate 7.8 are used to push the glass 9 to the lifting plate 8.3.

[0052] In the step 3), when the glass is transported to the lifting and conveying unit, the lower frame 5 rises to detect the next glass;

[0053] In the step 4), when the previous glass is detected by the first supporting wheel, the second supporting wheel is used to detect the glass in step 4); when the previous glass is detected by the second supporting wheel, the first supporting wheel is used to detect the glass in step 4).

[0054] In addition, the measurement and positioning method also includes a calibration step, in which the lifting and conveying unit rises, and the push rod 8.8 pushes the calibration plate 8.9 in the installation slot 8.3.1 to the lifting and conveying unit; the lifting and conveying unit descends, and the calibration plate 8.9 is conveyed to the top of the lower frame 5 by the second conveying unit and the first conveying unit; the calibration plate 8.9 is inspected by the rising lower frame 5, and the calibration plate 8.9 is rotated 90 degrees for inspection again; the lower frame 5 descends, and the calibration plate 8.9 is conveyed to the top of the lifting and conveying unit by the first conveying unit and the second conveying unit; the calibration plate 8.9 is inspected by the lifting and conveying unit, the lifting wheel 5.6, the second detection part and the first wheel 1.4, and then the calibration plate 8.9 is inspected by the lifting and conveying unit, the lifting wheel 5.6, the second detection part and the second wheel 1.5; the calibration plate 8.9 is pushed into the installation slot 8.3.1 by the lifting and conveying unit and the push plate 7.8.

[0055] Specifically, Figure 1-10 As shown, Figure 1 As shown, the glass is placed at the first conveying unit; then as Figure 2 As shown, lift the glass and fix it with a vacuum suction cup unit; then Figure 3 As shown, the first detection unit is used for detection; then as Figure 4 As shown in FIG. 1 , the glass is rotated 90 degrees and tested again using the first testing unit. After the test is completed, Figure 5 As shown, the glass is transported to the bottom of the lifting and conveying unit, and the next glass is transported to the top of the lower frame, so that the lifting and conveying unit can position and detect the glass, and the next glass can be detected at the lower frame, so that the detection and positioning efficiency is higher.

[0056] exist Figure 3 and Figure 4 In the step, in theory, the two first detection parts of the same inverted U-shaped frame clamp the glass from both sides, and the detection data of the two inverted U-shaped frames should be roughly equal. If they are equal, then Figure 6 As shown, the second wheel is used for positioning and detection, or as Figure 7 As shown in the figure, the first wheel is used for positioning and detection. The rule for selecting the first wheel or the second wheel is to select a wheel different from the previous glass. The detection at this time only detects the size of the glass in one direction. This size is also the size that the edge grinder needs to adjust according to. When the value detected at this time is Figure 4 When the values ​​detected in are roughly equal, the glass can continue to be transported to the edge grinding machine. Figure 3 Or the data measured in 4 does not meet the requirements (indicating that the glass may not be rectangular), or Figure 6Or 7 The measured data does not meet the requirements (indicating that the glass is unqualified, or a major failure occurred during the detection process and maintenance personnel are required to perform maintenance). Figure 8 As shown, the glass is pushed to the lifting plate by a push plate (the lifting plate can be raised and lowered, so that unqualified glass can be stacked as the lifting plate descends). In addition, when the unqualified glass is pushed by the push plate, the conveyor belt will actually descend slightly so that the upper surface of the conveyor belt corresponds to the strip groove. When the second detection unit is used for measurement, the height of the upper surface of the conveyor belt actually corresponds to the height of the first or second supporting wheel, so that one side of the measured glass can abut the lifting supporting wheel, and the other side can abut the first or second supporting wheel.

[0057] And after using it for a period of time, the first and second detection parts need to be calibrated, because the measurement of the glass size is actually obtained by converting the driving data of the first motor and the second motor. During calibration, the lifting plate is raised so that the installation slot is aligned with the conveyor belt unit, and the calibration plate is pushed from the installation slot to the conveyor belt unit by the push rod. Then the conveyor belt unit is lowered, and the calibration plate is transported to the top of the lower frame by the second conveyor unit and the first conveyor unit, so that the calibration plate is measured in a similar process to the glass. Since the size of the calibration plate is known, the first and second detection parts and the entire system can be judged based on the measurement data to determine whether they are working properly. After the calibration is completed, the calibration plate can be pushed into the installation slot again by the push plate, so that the calibration can be repeated the next time it is needed.

[0058] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
