Description

Technical field:

[0001] The utility model relates to the technical field of hollow glass production lines, in particular to an automatic glass thickness detection device. Background technology:

[0002] In an insulating glass production line, it is necessary to obtain the thickness of the glass sheet and / or the thickness of the glass sheet plus the aluminum frame (also called aluminum spacer, spacing frame) and / or the aluminum frame. There are two main technical means to obtain them in the prior art. One is to use manual measurement or manually input the required dimensions into the control system of the insulating glass production line according to the design dimensions. This manual input method has the problem of low efficiency and may also result in human input errors. The other is to use online automatic detection to directly transmit the detection results to the control system. This method has the advantages of high detection efficiency and reliable detection.

[0003] With the continuous promotion and application of automatic detection technology, users have given some feedback. Among them, the more prominent problem is that the detection accuracy sometimes deteriorates. Once the detection accuracy decreases, it directly affects the quality of subsequent product processing. According to user feedback, after in-depth analysis by technical personnel, it is concluded that the main reason for the poor detection accuracy sometimes is that when the glass conveyor deviates, the detection result will have a large error. Further analysis shows that the existing automatic detection technology is based on the rear support surface (that is, the glass will not deviate by default, the rear support surface is usually composed of wheels, and of course, other surfaces parallel to the rear support surface can also be used as a reference) as the reference, and then a displacement sensor is used at the front end to cooperate with the displacement drive for corresponding thickness detection. Therefore, once the glass deviates, measurement errors will occur. For example, a thickness measuring device for producing hollow glass previously applied by our company (authorization announcement number: CN217276026U). Therefore, it is necessary to improve and optimize the existing automatic glass thickness measurement technology in order to improve the detection accuracy.

[0031] Instructions for use of the automatic glass thickness detection device in this application:

[0032] like Figure 5-7 As shown, in actual application, the automatic glass thickness detection device of the present application needs to be installed in the existing insulating glass production line, the support roller 19 supports the lower end of the glass and can be transported, the support wheel 21 supports the back of the glass (the support wheel 21 is installed on the support frame 20), and the corresponding position can be installed according to actual needs. In the initial state, the detection cylinder A9 is extended, and the detection cylinder B11 is retracted. In the initial state, the distance from the detection plate 12 to the positioning block A5 is known, the detection stroke of the displacement sensor 10 is known, and the stroke of the detection cylinder B22 is known.

[0033] like Figure 8As shown in FIG. 1 , when the glass thickness needs to be checked, the glass (the aluminum frame 18 has been installed in front of the glass sheet 17) is transported by the supporting roller 19, and the transport is stopped after it is in place (at this time, the positioning block A5 and the positioning block B6 correspond to the position of the aluminum frame 18, the detection plate 12 corresponds to the position of the glass sheet 17, the positioning block B6 is located behind the glass sheet 17, and the positioning block A5 is located in front of the glass sheet 17, as shown in FIG. Figure 8 As shown in (a) of FIG. 1 ); the detection cylinder A9 is started, and the detection cylinder A9 begins to shrink, so that the distance between the positioning block A5 and the positioning block B6 gradually becomes smaller. At the same time, under the action of the spring 8, the positioning block A5 finally acts on the aluminum frame 18, and the positioning block B6 acts on the back of the glass sheet 17. At this time, the detection cylinder A9 cannot move further, and the displacement sensor 10 reads the moving distance (as shown in FIG. 1 ). Figure 8 As shown in (b) of FIG. 1 , the thickness of the glass (i.e., the glass sheet 17 plus the aluminum frame 18) can be obtained by subtracting the read moving distance from the detection stroke of the displacement sensor; then the detection cylinder B11 is started, and the detection cylinder B11 drives the detection plate 12 to extend and act on the front of the glass sheet 17 (as shown in FIG. Figure 8 (c) in the figure) and continue to extend (at this time, the detection cylinder B11 moves away from the glass sheet 17 due to the obstruction of the glass sheet 17. The detection cylinder B11 moves backward and drives the detection cylinder A9 and the displacement sensor 10 to move backward synchronously) until the detection cylinder B11 completes the stroke (as shown in the figure). Figure 8 As shown in FIG. 5( d ) in the figure, the displacement sensor 10 reads the moving distance, and the thickness of the aluminum frame 18 and the thickness of the glass sheet 17 can be calculated through the above-mentioned known quantities and the detection values ​​of the displacement sensor 10.
