Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass measurement, and particularly relates to a full-automatic photovoltaic glass thickness online measurement device. Background Art

[0002] In the production process of photovoltaic rolled glass, thickness, width and light transmittance are the main contents of control. For the rolling forming process, the control of glass plate thickness is the top priority of the work. First, the thickness is controlled in daily operation, second, it must be restored as soon as possible during the change of different thickness specifications, and third, the thickness must reach the required range in time after changing bricks and machines to reduce losses. All of these require comprehensive control and timely adjustment of thickness data. For photovoltaic rolled glass, the glass liquid is controlled by the guard brick and lip brick, and then flows through the calender to be pressed and cooled. The distance between the upper and lower rollers of the calender determines the thickness of the glass plate. As production continues, the pressure fluctuation of the pressure bar will cause changes in the thickness of the glass. At the same time, with the changes in the market, the glass thickness required by downstream manufacturers is also different. Among them, the replacement between glass plates with thicknesses of 2.0mm, 2.8mm, 3.2mm and other specifications is also more frequent. The original method of measuring thickness is to manually measure at the cold end at regular intervals, and then adjust the calender at the hot end. This obviously has data lag and is difficult to adjust in time, not to mention continuous data support, which affects the precise control of the thickness of the glass plate.

[0003] To solve these problems, it is necessary to study the timely feedback of glass plate thickness data, that is, how to change the original manual timed measurement of photovoltaic glass thickness to full-time measurement in a fully automatic way, realize fully automatic measurement, recording and analysis of photovoltaic glass thickness, and ensure that process personnel can view thickness data in the control room, thereby fundamentally solving the above problems.

[0033] The sliding track is also provided with a connecting piece 210 for connecting with the bracket device 1 , and the connecting piece 210 is configured as an L-shaped structure to facilitate the connection between the crossbeam 102 and the sliding track 207 .

[0034] The following is further described in conjunction with specific embodiments:

[0035] 1. Assembly of online thickness measurement device:

[0036] Weld the two columns 101 of the support device 1 with the two bases 103, and fix them on both sides of the conveyor belt of the glass plate production line through anchor bolts 104, and fix the tops of the two columns 101 of the crossbeam 102. Fix the track body 207 on the support crossbeam 102 through the connecting piece 210, and insert the mobile measuring device 3 from either end of the track body 207 so that its upper arc groove 301 is in close contact with the upper arc track 208 of the driving mechanism 2, and the lower arc groove 302 is in close contact with the lower arc track 209 of the driving mechanism 2. Move the mobile measuring device 3 left and right to check its smoothness, and install the driving motor 201, the driving gear 202, and the driven gear 203 on the " Figure 2" Corresponding position, the synchronous rack belt 204 bypasses the driving gear 202 and the driven gear 203 and is connected to the mobile measuring device 3 using the rack belt left joint 205 and the rack belt right joint 206, thus forming a "mechanism in which the driving motor 201 drives the mobile measuring device 3 to move through the driving gear 202, the driven gear 203 and the synchronous rack belt 204".

[0037] Fix the laser measurement sensor 304 on the sliding block of the mobile measurement device 3 and protect it with the sensor protection cover 305, fix the glass plate deformation detector 503 at a suitable height above the glass plate 501, connect the drive motor 201, the laser measurement sensor 304, the glass plate deformation detector 503, etc. to the control cabinet of the control and display system, connect the control cabinet to electricity, input a specific program, and the installation process is completed.

[0038] 2. Preliminary setting and debugging of the control system:

[0039] Open the "settings page", input the origin coordinate X0, the coordinates of each measuring point X1, X2...Xn and the pause delay t between each position; open "manual measurement", move the mobile measuring device 3 to the corresponding measuring point, the dynamic cursor 405 will light up during the forward movement, and the measuring position indicator light 406 will light up after reaching the position to be measured. At this time, the thickness data in the corresponding "thickness data display box 403" can be read, and the thickness data of each position to be measured can be read in the same way. Here, you can first enter a correction value in the "thickness correction coefficient display box 404 for each position", and then you can re-correct it according to the actual situation; open the "alarm page", and input the out-of-tolerance alarm value of each type of thickness, the glass plate deformation alarm value and other abnormal alarms.

[0040] 3. Use of online measuring device:

[0041] After the device is started, click "Operation Page". At this time, the mobile measuring device 3 is at the origin position. When the operation screen switches to the "Automatic Measurement" state, the mobile measuring device 3 starts thickness measurement from position X1 to Xn, and then from Xn to X1 in sequence. Each time interval is a preset pause delay t. For the data obtained by automatic measurement, the thickness of the actual glass plate can be measured manually, and the difference between the two can be used to correct it in the "Thickness Correction Coefficient Display Box 404 at Each Position". During use, the thickness data can be recorded and can be reviewed by opening the "History Record" interface. When the thickness data exceeds the alarm range, an alarm will be issued, and the "Fault" light in the "Control Status Display 408" will light up. When a display is also connected to the hot end control room, the operator will be able to grasp the changes in the thickness of the glass plate in the control room at any time and take timely countermeasures.

[0042] During the production process, when the glass plate is deformed, it can be detected by the beam switch 504 and the reflector 505; when the glass plate is missing due to reasons such as machine replacement, it can be detected by the glass plate detector 503. In both cases, an alarm will be triggered, and the fault alarm light 402 on the control cabinet will flash. To prevent damage to the measuring device, the mobile measuring device 3 will automatically return to the original position. After the fault is resolved and the alarm is eliminated, the measuring device 3 will automatically return to the measuring state.

[0043] The fully automatic online photovoltaic glass thickness measuring device changes the original manual timed measurement of photovoltaic glass thickness into a full-time fully automatic measurement. The measuring system cooperates with the control and display system 4. Through the combined setting of the servo system, CPU and IO modules, the host computer with a database installed, and the on-site human-machine interface of the control and display system 4, and after program design, it can realize the fully automatic measurement, recording and analysis of the photovoltaic glass thickness, ensuring that process personnel can view the thickness data in the control room, fundamentally solving the above problems.
