[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5A photoelectric width measuring device includes a dual-axis cylinder 1 and a photoelectric sensor 12. The lower end of the dual-axis cylinder 1 is bolted to a width measuring cylinder connecting plate 2. A magnet 7 with a seat is threaded through the front plate of the width measuring cylinder connecting plate 2 on its left side. An internally threaded cylinder 13 is fixedly installed at the rear end of the width measuring cylinder connecting plate 2. The rear end of the photoelectric sensor 12 passes through the width measuring cylinder connecting plate 2 and is threaded into the interior of the internally threaded cylinder 13. A photoelectric sensor 12 has a photoelectric sensor bracket copper sleeve shaft 6 at its front end. A copper alloy straight sleeve bearing 5 is movably sleeved on the outer side of the photoelectric sensor bracket copper sleeve shaft 6. A measuring magnet 7 is movably sleeved on the outer ring of the copper alloy straight sleeve bearing 5. The upper end of the wide contact block 3 and the base magnet 7 are magnetically connected to the width measuring contact block 3. The lower end of the width measuring contact block 3 has a corresponding insertion hole 14 at the photoelectric sensor 12. A width measuring contact probe 4 is slidably installed inside the insertion hole 14. A cylindrical inductive sensor 11 is threaded through and threaded onto the right side of the front plate of the width measuring cylinder connecting plate 2. When the glass product enters the measurement area, the cylindrical inductive sensor 11 can detect changes in the electromagnetic field caused by the object's edge, thereby accurately determining the edge position of the glass product. Then, the dual-axis cylinder 1 is opened, causing its output end to drive the width measuring cylinder connecting plate 2 downwards. The descent of the contact plate 2 causes the width measuring contact probe 4 to descend, simultaneously activating the photoelectric sensor 12. With the assistance of the cylindrical inductive sensor 11, the photoelectric sensor 12 captures the edge position of the glass in real time through the photoelectric effect. This synergistic effect not only enables the photoelectric sensor 12 to perform high-precision measurements but also achieves high-precision edge detection and calibration, resulting in a precise alignment measurement. This ensures that the width measuring contact probe 4, driven by the dual-axis cylinder 1, accurately contacts the expected measurement position on the glass, thereby acquiring a more accurate initial width signal. This combination of mechanical contact and non-contact sensing effectively addresses both detection and non-contact sensing needs. It boasts advantages such as high-precision measurement and enhanced adaptability. Notably, the design of the copper alloy straight sleeve bearing 5, the copper sleeve shaft 6 of the photoelectric sensor bracket, and the magnet with a seat ensures stable operation and anti-interference capabilities. Furthermore, the signals acquired by the width measuring contact probe 4 and the photoelectric sensor 12 are fused within the device to form a composite signal. After conversion by the cylindrical inductive sensor 11, these composite signals are transmitted to the control system for further calibration and processing, ultimately outputting the precise width value of the measured object. This is crucial for automated production lines and measuring equipment that require high-precision positioning and calibration.
[0022] Please see Figures 3-5The lower end of the width measuring contact block 3 is fixedly installed with an external threaded cylinder 15 at the insertion hole 14. Two sets of gradually changing fastening plates 16 are symmetrically arranged at the lower end of the external threaded cylinder 15. The width measuring contact probe 4 extends through the gradually changing fastening plates 16 and the external threaded cylinder 15 into the insertion hole 14. A nut sleeve 17 is threadedly fitted on the outer side of the external threaded cylinder 15. A retaining sleeve 18 is slidably fitted on the outer side of the external threaded cylinder 15 at the lower side of the nut sleeve 17. The width measuring contact block 3 of this device is rotatably fitted onto the copper sleeve shaft 6 of the photoelectric sensor bracket through a copper alloy straight sleeve bearing 5. The seated magnet 7 is a built-in magnet, which can attract and fix the width measuring contact block 3 through magnetic attraction. The height of the seated magnet 7 can be adjusted by directly rotating it, so that the angle of the width measuring contact block 3 can be adjusted, keeping the width measuring contact block 3 vertically fixed and preventing the width measuring contact probe 4 from tilting. Compared with fixing methods such as bolt fixing, this fixing method can not only keep the width measuring contact block 3. It can withstand certain external impacts and vibrations, and at the same time, it can quickly separate the seated magnet 7 from the width measuring contact block 3, so that the width measuring contact block 3 can be directly removed from the photoelectric sensor 12's photoelectric sensor bracket copper sleeve shaft 6 and copper alloy straight sleeve bearing 5. Then, the photoelectric sensor 12 and cylindrical inductive sensor 11 and other equipment can be removed for replacement and maintenance. In addition, by turning the nut sleeve 17 upward, its limiting effect on the clamping sleeve 18 can be released, so that the clamping sleeve 18 can further release its limiting effect on the gradual fastening plate 16. After the gradual fastening plate 16 releases its fastening effect on the width measuring contact probe 4, it can be directly pulled out for replacement or maintenance. Similarly, the installation can be completed by simply turning the nut sleeve 17 downward to complete the installation and fixation of different models of width measuring contact probe 4. By adopting this split structure, it is easy to achieve the purpose of quick disassembly and assembly and functional expansion.
[0023] Please see Figure 2 and Figure 5 The lower end of the width measuring contact probe 4 is lower than the lower end of the cylindrical inductive sensor 11 to ensure the rationality of the structural design. A check pad 8 is fixedly installed at the front end of the copper sleeve shaft 6 of the photoelectric sensor bracket to prevent the front end of the copper sleeve shaft 6 of the photoelectric sensor bracket from being worn or damaged due to frequent contact, thus extending its service life. The right end of the width measuring contact block 3 is threaded with an internal hexagonal head screw 9. Three sets of deep groove ball bearings 10 are fixedly sleeved on the smooth part of the screw on the internal hexagonal head screw 9 to improve the compatibility of the device and for functional expansion. The rear end of the dual-axis cylinder 1 is bolted to a right-angle piece 19. In use, the device is fixedly installed in a suitable position in the automated production line for glass products through the right-angle piece 19.
[0024] Working Principle: During operation, when the glass product enters the measurement area, the cylindrical inductive sensor 11 detects changes in the electromagnetic field caused by the object's edge. Then, the dual-axis cylinder 1 is activated, causing its output end to lower the width-measuring cylinder connecting plate 2. This descent of the connecting plate 2 lowers the width-measuring contact probe 4. Simultaneously, the photoelectric sensor 12, aided by the cylindrical inductive sensor 11, captures the glass edge position in real time through the photoelectric effect. This ensures that the width-measuring contact probe 4, driven by the dual-axis cylinder 1, accurately contacts the glass at the expected measurement position, thus obtaining a more precise initial width signal. Furthermore, the width-measuring contact block 3 is rotatably mounted on the copper sleeve shaft 6 of the photoelectric sensor bracket via a copper alloy straight-sleeve bearing 5. The base magnet 7 is a built-in magnet, which magnetically attracts and fixes the width-measuring contact block 3. The height of the base magnet 7 can be adjusted by directly rotating it, allowing for angle adjustment of the width-measuring contact block 3. To keep the width measuring contact block 3 vertically fixed and prevent the width measuring contact probe 4 from tilting, compared to fixing methods such as bolt fixing, this fixing method not only allows the width measuring contact block 3 to withstand certain external impacts and vibrations, but also allows the seated magnet 7 to be quickly separated from the width measuring contact block 3. This allows the width measuring contact block 3 to be directly removed from the photoelectric sensor 12's photoelectric sensor bracket copper sleeve shaft 6 and copper alloy straight sleeve bearing 5. This allows the photoelectric sensor 12 and cylindrical inductive sensor 11 to be removed for replacement and maintenance. In addition, by turning the nut sleeve 17 upward, its limiting effect on the clamping sleeve 18 can be released, allowing the clamping sleeve 18 to further release its limiting effect on the gradient fastening plate 16. After the gradient fastening plate 16 releases its fastening effect on the width measuring contact probe 4, it can be directly pulled out for replacement or maintenance. Similarly, installation can be completed by simply turning the nut sleeve 17 downward to install and fix different models of width measuring contact probe 4.
