[0003] In existing technologies, photocells and proximity switches are key components for the accurate detection of glass side length. However, photocells and proximity switches are usually used independently. Photocells typically detect the position of an object by emitting and receiving infrared light, while proximity switches use principles such as magnetic field induction to detect the proximity of an object. This independent use method lacks integrated collaborative design, which leads to the need for separate positioning, fixing, and debugging of photocells and proximity switches during installation. This cumbersome operation increases installation time and labor costs, affecting the accuracy and reliability of glass side length detection. Utility Model Content

It solves the problem that in existing technologies, the photocell and proximity switch are used independently without integrated collaborative design, which leads to the need for separate positioning, fixing and debugging of the photocell and proximity switch during installation. This is cumbersome, increases installation time and labor costs, and affects the accuracy and reliability of glass side length detection.
[0005] This utility model provides the following technical solution: a glass-side long detection structure based on a proximity switch, including a photoelectric sensor bracket for infeeding, a detection component, and a mounting component. The detection component includes a photoelectric sensor mounting threaded plate, with a photoelectric sensor disposed inside the photoelectric sensor mounting threaded plate. The photoelectric sensor bracket for infeeding is fixedly connected to the photoelectric sensor wheel bracket for infeeding via hexagonal head bolts. A copper alloy inlaid solid lubricated straight sleeve bearing is disposed on the surface of the hexagonal head bolts.

[0013] 2. With the installation component set up, the operator only needs to pull the lever to place the detection component on the glass production line. After releasing the lever, the spring returns to its original deformation and pushes the abutment down. The anti-slip pad is pressed tightly against the surface of the glass production line, and the detection component is firmly installed by the clamping action to prevent it from sliding on the production line.

[0018] 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.
[0019] Please see Figure 1 - Figure 3This utility model provides an embodiment of a glass side length detection structure based on a proximity switch, including a photoelectric sensor bracket 1, a detection component 2, and a mounting component 6. The detection component 2 includes a photoelectric sensor mounting threaded plate 21, with a photoelectric sensor 22 disposed inside the photoelectric sensor mounting threaded plate 21. The photoelectric sensor bracket 1 is fixedly connected to the photoelectric sensor wheel bracket 24 via a hexagonal head bolt 23. The surface of the hexagonal head bolt 23 is provided with a copper alloy inlaid solid lubricated straight sleeve bearing 25. The surface of the photoelectric sensor wheel bracket 24 is threadedly connected to a first internal hexagonal head screw 26. The surface of the first internal hexagonal head screw 26 is rotatably connected to a small wheel 27. The surface of the small wheel 27 is fixedly connected to a large wheel 28. The photoelectric sensor mounting... The threaded plate 21 has an internally threaded magnet 29 with a built-in magnet and a proximity switch model 211 inside. The surface of the photoelectric sensor support 24 is threaded with a second hexagonal head screw 212. The surface of the second hexagonal head screw 212 is symmetrically equipped with deep groove ball bearings 213. The photoelectric sensor support 1 has an L-shaped structure. The photoelectric sensor mounting threaded plate 21 is fixedly connected to one side surface of the photoelectric sensor support 1. The photoelectric sensor 22 works in conjunction with the proximity switch model 211. The photoelectric sensor 22 senses the glass position information, and the proximity switch model 211 accurately detects the side length of the glass. The large support wheel 28 and the small support wheel 27 assist in the glass movement and positioning, ensuring accurate detection. Accurate measurement is achieved, completing the glass side length detection task. The copper alloy inlaid solid lubricated straight-sleeve bearing 25 on the surface of the hexagonal head bolt 23 provides lubrication. The infeed photoelectric sensor bracket 1 is the supporting foundation of the entire detection structure. Its L-shaped design ensures structural stability and ease of installation. The infeed photoelectric sensor bracket 1 provides a stable mounting platform for other components. The photoelectric sensor mounting threaded plate 21 is fixedly connected to one side of the infeed photoelectric sensor bracket 1. The photoelectric sensor 22 inside accurately detects the edge position of the glass slide by emitting and receiving infrared light. The high-precision detection capability of the photoelectric sensor 22 ensures accurate measurement of the glass side length and transmits the data to the control system. The control system is based on existing technology and integrates the photoelectric sensor 22 and proximity switch. Model 211 is electrically connected to process data signals fed back from the photoelectric sensor 22 and the proximity switch model 211. A built-in magnet 29 with a mounting magnet is threaded into the photoelectric sensor mounting plate 21. The proximity switch model 211 utilizes the principle of magnetic field induction to assist the photoelectric sensor 22 in position detection, improving detection redundancy and reliability. When the glass plate approaches, the proximity switch model 211 senses the change in magnetic field and triggers a signal output. The photoelectric sensor wheel bracket 24 is fixedly connected to the photoelectric sensor bracket 1 via hexagonal head bolts 23. A copper alloy inlaid solid-lubricated straight-sleeve bearing 25 on the bolt surface effectively reduces rotational friction, improving the durability and stability of the structure.The small guide wheel 27 and the large guide wheel 28 are rotatably connected to the surface of the glass feed photoelectric sensor guide wheel bracket 24 via the first hexagon socket head cap screw 26. The large guide wheel 28, fixedly connected to the surface of the small guide wheel 27, forms a double-wheel support structure, providing stable glass sheet conveying support. This allows for adjustment of the glass sheet conveying angle by rotation to adapt to different production needs. The second hexagon socket head cap screw 212 is symmetrically arranged on the surface of the glass feed photoelectric sensor guide wheel bracket 24, and the deep groove ball bearings 213 symmetrically mounted on its surface provide rolling support for the glass sheet conveying, further reducing conveying resistance and improving production efficiency. This is suitable for the precise detection and control of glass length, position, and edges in automated glass production lines. The photoelectric sensor bracket (FBM-Z-3B25) adopts a modular design, fixing the photoelectric sensor 22 and adjusting its detection angle to ensure high-precision identification of glass edges. The photoelectric sensor mounting threaded plate 21 (YC2022-Q04) is used to stably mount the photoelectric sensor 22, providing a threaded interface to accommodate different sensor models. The (M8) proximity switch model 211 works in conjunction with the photoelectric sensor 22, using magnetic field induction to assist in detecting the glass position and improve the reliability of redundant detection.
[0020] Please see Figure 1 - Figure 3 The mounting assembly 6 includes a backing plate 61. Anti-slip pads 62 are provided on the opposing surfaces of the backing plate 61 and the photoelectric sensor bracket 1. Guide rods 63 are symmetrically fixedly connected to the top surface of the photoelectric sensor bracket 1. Springs 64 are fitted onto the surfaces of the guide rods 63. Limit rings 65 are fixedly connected to the top surfaces of the guide rods 63. Guide holes 66 are symmetrically formed on the top surface of the backing plate 61. A pull rod 67 is fixedly connected to the center surface of the top of the backing plate 61. The backing plate 61 and the photoelectric sensor bracket 1 are positioned opposite each other. The backing plate 61 is slidably connected to the surface of the guide rods 63 through the guide holes 66. One end of each spring 64 is fixedly connected to the bottom surface of the limit ring 65, and the other end of each spring 64 is fixedly connected to the top surface of the backing plate 61. The length of the pull rod 67 is longer than the length of the guide rod 63. Anti-slip pads 62 are provided on the opposing surfaces of the support plate 61 and the photoelectric sensor bracket 1. The clamping action securely installs the detection component 2 on the glass production line. The design of the anti-slip pads 62 increases friction and prevents the detection component 2 from sliding on the production line. The guide holes 66 symmetrically opened on the top of the support plate 61 slide in cooperation with the guide rod 63, ensuring the smooth vertical movement of the support plate 61. The pull rod 67 is fixedly connected to the center of the top of the support plate 61. Its length is longer than the guide rod 63, which makes it easy for the operator to lift the pull rod 67 to move the support plate 61 vertically upward, thereby easily completing the installation and disassembly of the detection component 2. When the pull rod 67 is released, the elastic force of the spring 64 pushes the support plate 61 downward, so that the anti-slip pads 62 are in close contact with the surface of the glass production line, ensuring the stable installation of the detection component 2.
[0021] Working principle: During operation, the operator installs the detection component 2 on the side of the glass production line via the mounting component 6. Pulling the pull rod 67 causes the abutment plate 61 to slide upward along the guide rod 63, compressing the spring 64. An installation space is formed between the abutment plate 61 and the infeed photoelectric sensor bracket 1. The device is placed in the required installation position. Releasing the pull rod 67 causes the spring 64 to return to its original shape, pushing the abutment plate 61 downward. Under the action of the anti-slip pad 62, the device is fixed in the required installation position. Then, the detection positions of the photoelectric sensor 22 and the proximity switch model 211 are adjusted. When the glass sheet passes through the detection area, the photoelectric sensor 22 first captures the edge position information of the glass and transmits the signal to the control system. At the same time, the proximity switch model 211 also verifies the position information of the glass through magnetic field induction. When the detection results of the two sensors are consistent, the control system will confirm that the position and length information of the glass are correct and continue to perform subsequent processing operations. If the detection results are inconsistent or an abnormality occurs, the control system will issue an alarm and stop the processing operation to avoid errors or damage.
