Description

Technical Field

[0001] The present invention relates to the technical field of glass detection equipment, and in particular to a device and method for detecting the curvature of bulletproof glass. Background Art

[0002] With the widespread application of bulletproof glass in military, security and other fields, the requirements for its quality and performance testing are becoming increasingly stringent. The curvature of bulletproof glass, as one of the key performance indicators, is directly related to its protective effect and safety of use.

[0003] There are often many problems in traditional detection methods. On the one hand, the detection environment lacks effective shielding measures, and external electromagnetic interference and other environmental factors can easily affect the stability of the detection instrument, resulting in deviations in the measurement data and failure to accurately reflect the true curvature of the bulletproof glass. On the other hand, the pretreatment of the bulletproof glass before detection is not perfect, and problems such as dust, impurities and uneven coating thickness on the glass surface have not been fully resolved. These factors will seriously interfere with the accuracy of curvature detection, greatly reducing the reliability of the test results. Moreover, previous detection equipment lacks flexibility and accuracy in structural design, making it difficult to adapt to bulletproof glass of different sizes and shapes. The detection efficiency is low and cannot meet the needs of large-scale production detection.

[0004] Therefore, there is an urgent need for a new type of bulletproof glass curvature detection equipment that can effectively overcome the above problems, achieve high-precision and high-efficiency detection, and provide strong guarantees for the quality control and performance improvement of bulletproof glass.

[0009] Furthermore, support blocks are movably arranged below the opposite sides of the two clamping frames, and the two support blocks are telescopically driven by micro electric cylinders arranged inside the clamping frames.

[0010] Furthermore, the processing unit comprises a fixing frame, and the fixing frames are symmetrically fixedly arranged at the top and bottom of the right side inside the shielding detection frame, and the adjustment frames are movably arranged on the opposite sides of the two fixing frames.

[0011] Furthermore, servo electric cylinders are fixedly arranged on all four sides inside the fixed frame, and the driving ends of the four servo electric cylinders are fixedly connected to the four sides of the bottom of the adjusting frame, cleaning brushes are rotatably arranged on the left and right sides inside the adjusting frame, and the two cleaning brushes are driven to rotate by a motor arranged at the bottom of the adjusting frame, and dust suction pipes are symmetrically fixedly arranged on the left and right sides inside the adjusting frame, and the bottom ends of the two dust suction pipes are connected to the dust collecting trough arranged inside the fixed frame through a dust suction pump.

[0012] Furthermore, an electric slide table 1 is fixedly arranged in the middle of the adjusting frame, and a coating thickness gauge is slidably arranged on the top of the electric slide table 1.

[0013] Furthermore, linear slide rails three are fixedly arranged on the left and right sides inside the shielding frame, and the tops of the two linear slide rails three are slidably connected to the left and right sides of the bottoms of the two sliding frames respectively, and electric slides two are fixedly arranged inside the two sliding frames, and a plurality of linear modules are slidably arranged on one side of the electric slide two, and detection heads are fixedly arranged on the driving ends of the plurality of linear modules.

[0014] Furthermore, a plurality of detection heads arranged inside the two sliding frames respectively adopt capacitive displacement sensors and laser displacement sensors.

[0015] Furthermore, a method for detecting the curvature of a bulletproof glass comprises the following steps: Step 1: Use two linear slide rails 1 to drive the movable frame to slide to the rightmost side of the shielding detection frame. At this time, the right half of the movable frame is outside the shielding detection frame. Then use two linear slide rails 2 to drive the unloading frame to slide to the rightmost side of the movable frame. At this time, the unloading frame as a whole is outside the shielding detection frame. Step 2: put the bulletproof glass to be tested into the unloading rack, and control the support blocks on the lower sides of the two clamping racks to extend at the same time, adjust the spacing between the two clamping racks according to the size of the bulletproof glass to be tested, and adjust the two clamping racks to one side of the left and right sides of the bulletproof glass by controlling the extension stroke of the driving ends of the driving electric cylinders on the left and right sides, put the bulletproof glass into the unloading rack, and use the two support blocks to support the bottom of the left and right sides of the bulletproof glass. At this time, the driving ends of the clamping electric cylinders inside the two clamping racks cooperate with the clamping plates to push the rubber pad and the left and right sides of the bulletproof glass to fit together; Step 3: Use two linear slide rails to drive the movable frame to slide into the shielding detection frame. At this time, the two fixed shielding plates and the movable shielding plate on the left and right sides cooperate with each other to temporarily seal the inside of the shielding detection frame. Use the servo electric cylinder driving end inside the two fixed frames to control the upper and lower adjustment frames to approach the upper and lower surfaces of the bulletproof glass. Use the upper and lower cleaning brushes to clean the dust on the upper and lower surfaces of the bulletproof glass. At the same time, use the coating thickness gauge to detect the coating thickness on the detection surface of the bulletproof glass. Step 4. After completing the cleaning process of the upper and lower surfaces of the bullet-proof glass, the driving unit drives the bullet-proof glass to move between the upper and lower shielding frames. At this time, the driving ends of several linear modules inside one of the upper and lower sliding frames are controlled to drive the detection head to move to the upper and lower parts of the unloading rack respectively. Infrared level sensors are arranged at the upper and lower parts of the unloading rack. The infrared level sensors are used to detect the horizontal positions of several detection heads at the upper and lower parts to ensure that the positions of several detection heads are unified before detection. Then, the driving ends of several linear modules are used to control several detection heads to approach the upper and lower surfaces of the bullet-proof glass until one side of several detection heads contacts the surface of the bullet-proof glass. The displacement distance is recorded by several detection heads. By comparing the displacement distances of the detection heads at several detection points, the displacement distance curves of each detection point are drawn to obtain the curvature of the bullet-proof glass, thereby completing the curvature detection operation of the bullet-proof glass.

[0016] Compared with the prior art, it has the following beneficial effects: 1. The movable partition is controlled by the driving ends of the two lifting electric cylinders to slide up and down inside the shielding detection frame, and the left and right sides of the shielding detection frame are divided into two processing chambers by the movable partition. The upper and lower surfaces of the bullet-proof glass are simultaneously cleaned and the thickness of the coating is measured in the processing chamber on the right side of the shielding detection frame. On the one hand, the cleanliness of the surface of the bullet-proof glass can be ensured, thereby improving the subsequent detection accuracy of the curvature of the bullet-proof glass. On the other hand, it can avoid the uneven coating thickness or poor adhesion of the coating on the surface of the bullet-proof glass. The impact on the accuracy of the result of the curvature detection of the bullet-proof glass.

[0017] 2. When the bulletproof glass is sent into the shielding detection frame for curvature detection, the two fixed shielding plates and the movable shielding plate on the left and right sides cooperate with each other to temporarily seal the inside of the shielding detection frame, which greatly reduces the interference of external factors on the detection process, especially effectively avoids the influence of external electromagnetic on the detection instrument, ensures the stability of the detection instrument during operation, and thus creates a good environmental condition for obtaining accurate curvature detection results.

[0018] 3. During the unloading stage, the present invention can easily and completely move the unloading rack out of the shielding detection rack, which greatly facilitates the placement of the bullet-proof glass to be detected, avoids the inconvenience of operation in a small enclosed space, and improves work efficiency. In addition, the through-hole design at the bottom of the movable rack provides necessary conditions for the detection and processing of the lower surface of the bullet-proof glass, ensures the comprehensiveness and feasibility of the detection and processing of the upper and lower surfaces, avoids the detection blind area caused by unreasonable structure, and helps to improve the detection accuracy. In addition, through the combined design of multiple driving electric cylinders, clamping electric cylinders, clamping plates and rubber pads, the spacing can be flexibly adjusted and tightly clamped according to the size specifications of the bullet-proof glass. The setting of the rubber pad can not only ensure the stability of clamping, but also avoid damage to the glass surface.

[0019] 4. Through the combination of electric slide table 2 and linear module, the displacement of the detection head can be further accurately controlled to achieve detailed detection of multiple points on the glass surface, improve the comprehensiveness and accuracy of the detection, and use capacitive displacement sensor and laser displacement sensor as the detection head, which can give full play to the advantages of both, measure the curvature of the glass from different angles and principles, complement and verify each other, and enhance the reliability of the detection results.

The impact on the accuracy of the result of the curvature detection of the bulletproof glass.

[0025] Furthermore, two fixed shielding plates 4 are fixedly provided on the left and right sides of the shielding detection frame 1, and the two fixed shielding plates 4 on the left and right sides are symmetrically arranged up and down, a feeding gap is arranged between the upper and lower two fixed shielding plates 4, and movable shielding plates 5 are slidably arranged on the opposite sides of the upper and lower two fixed shielding plates 4 through an electric controller; by utilizing the combined structure of the fixed shielding plates 4 and the movable shielding plates 5 on the left and right sides of the shielding detection frame 1, when the bulletproof glass is fed into the interior of the shielding detection frame 1 for curvature detection, the structural cooperation of the two fixed shielding plates 4 and the movable shielding plates 5 on the left and right sides is utilized to temporarily close the interior of the shielding detection frame 1, thereby being able to greatly reduce the adverse effects of external factors on the curvature detection process, avoid the detection instrument from being affected by external electromagnetic influences during operation, and ensure the stability of the detection instrument during operation.

[0026] Furthermore, a driving unit 6 is movably arranged inside the shielding detection frame 1, and a processing unit 7 is arranged on the right side inside the shielding detection frame 1, and a detection unit 8 is arranged on the left side inside the shielding detection frame 1; when performing curvature detection of the bulletproof glass, the bulletproof glass is positioned and clamped by the driving unit 6, and at the same time, the bulletproof glass is driven to move to the left and right sides inside the shielding detection frame 1, and the upper and lower surfaces of the bulletproof glass are synchronously preprocessed by the processing unit 7 arranged on the right side inside the shielding detection frame 1, and finally, the upper and lower surfaces of the bulletproof glass are synchronously measured by the detection unit 8 arranged on the left side inside the shielding detection frame 1. By synchronously preprocessing and detecting the curvature of the upper and lower surfaces of the bulletproof glass, the detection accuracy and efficiency of the bulletproof glass can be greatly improved.

[0027] In a specific embodiment, the present invention uses two lifting electric cylinders 3 to accurately control the movable partition 2 to slide up and down in the shielding detection frame 1, and divides the interior into two processing chambers on the left and right. In this way, in the processing chamber on the right side of the shielding detection frame 1, the upper and lower surfaces of the bullet-proof glass can be cleaned and the thickness of the coating can be measured simultaneously. On the one hand, it ensures that the surface of the bullet-proof glass is clean and free of impurities, effectively reduces the detection error caused by dust, stains, etc., and significantly improves the subsequent curvature detection accuracy; on the other hand, it accurately measures and processes the coating thickness problem, avoids the adverse effects of uneven coating or coating with poor adhesion on the accuracy of the detection result, and makes the detection data more reliable; when the bullet-proof glass is sent into the shielding detection frame 1 for curvature detection During the test, the two fixed shielding plates 4 and the movable shielding plate 5 on the left and right sides cooperate with each other to temporarily close the inside of the shielding detection frame 1, which greatly reduces the interference of external factors on the detection process, especially effectively avoids the influence of external electromagnetic on the detection instrument, and ensures the stability of the detection instrument during operation, thereby creating a good environmental condition for obtaining accurate curvature detection results. Moreover, the reasonable layout and coordinated work of the driving unit 6, the processing unit 7 and the detection unit 8 can position, clamp and drive the bulletproof glass while simultaneously pre-processing and detecting the curvature of the upper and lower surfaces. This integrated design not only improves the detection accuracy, but also greatly improves the detection efficiency, making the entire detection process more efficient, accurate and stable.

[0028] See also Figures 3 to 5 As shown, specifically, the driving unit 6 includes a movable frame 10 and a material discharging frame 12, and linear slide rails 9 are fixedly arranged on both sides of the front and rear of the inner wall of the shielding detection frame 1, and the movable frame 10 is slidably arranged between the opposite sides of the two linear slide rails 9, wherein the middle parts of the front and rear sides of the movable frame 10 are respectively slidably connected to one side of the two linear slide rails 9, so when the movable frame 10 is controlled to slide to the rightmost or leftmost side of the shielding detection frame 1, half of the area of ​​the movable frame 10 will be outside the shielding detection frame 1, and in addition, a through opening is also provided at the bottom of the movable frame 10 to facilitate the curvature detection of the lower surface of the bulletproof glass. And cleaning and coating thickness measurement processing; the front and rear sides of the inner wall of the movable frame 10 are fixedly provided with linear slide rails 11, and a material discharge rack 12 is slidably provided between the opposite sides of the two linear slide rails 11. The connection relationship between the front and rear sides of the material discharge rack 12 and the two linear slide rails 11 is the same as the connection method between the movable frame 10 and the two linear slide rails 9. Therefore, when the movable frame 10 slides to the leftmost or rightmost side, the material discharge rack 12 is controlled to slide to the same side edge. At this time, the entire material discharge rack 12 will be outside the shielding detection frame 1, so as to facilitate the placement of the bulletproof glass inside the material discharge rack 12.

[0029] Furthermore, two driving electric cylinders 13 are fixedly arranged on both the front and rear sides of the inner wall of the unloading rack 12, and clamping racks 14 are slidably arranged on both the left and right sides of the inside of the unloading rack 12, and the front and rear sides of the two clamping racks 14 are respectively fixedly connected to the driving ends of the two driving electric cylinders 13 arranged on the same side, and the front and rear sides of the clamping racks 14 are respectively slidably connected to the front and rear sides of the inner wall of the unloading rack 12; Furthermore, a plurality of clamping electric cylinders 15 are fixedly provided on one side opposite to the two clamping frames 14, and a clamping plate 16 is fixedly provided on the driving end of each of the clamping electric cylinders 15; a rubber pad 17 is provided on one side opposite to the two clamping frames 14, and the two rubber pads 17 are respectively fixedly connected to the plurality of clamping plates 16 provided on the same side; a support block 18 is movably provided below one side opposite to the two clamping frames 14, and the two support blocks 18 are telescopically driven by a micro electric cylinder provided inside the clamping frames 14.

[0030] It should be noted that when positioning and feeding the bulletproof glass, the movable frame 10 is driven to slide to the rightmost side of the shielding detection frame 1 by two linear slide rails 19. At this time, the right half of the movable frame 10 is outside the shielding detection frame 1, and then the unloading frame 12 is driven to slide to the rightmost side of the movable frame 10 by two linear slide rails 11. At this time, the unloading frame 12 is outside the shielding detection frame 1 as a whole, and the bulletproof glass to be detected is placed inside the unloading frame 12. At the same time, the support blocks 18 at the lower sides of the two clamping frames 14 are controlled to extend, and the spacing between the two clamping frames 14 is adjusted according to the size specifications of the bulletproof glass to be detected. The two clamping frames 14 are adjusted to the bulletproof position by controlling the extension stroke of the driving ends of the driving electric cylinders 13 on the left and right sides. On one side of the left and right sides of the glass, the bullet-proof glass is placed inside the unloading rack 12, and the bottom of the left and right sides of the bullet-proof glass are supported by two supporting blocks 18. At this time, the driving ends of several clamping electric cylinders 15 inside the two clamping racks 14 cooperate with the clamping plates 16 to push the rubber pad 17 and the left and right sides of the bullet-proof glass to fit together, and according to the shapes of the two sides of the bullet-proof glass, the tight fit of each fitting point can be guaranteed, and the clamping stability of the bullet-proof glass between the two clamping racks 14 is guaranteed. When the surface of the bullet-proof glass is cleaned and the curvature is detected, the two supporting blocks 18 are controlled to be reset inside the two clamping racks 14 to avoid interference with the cleaning and curvature detection operations on the surface of the bullet-proof glass.

[0031] In a specific embodiment, the present invention can easily and completely move the unloading rack 12 out of the shielding detection rack 1 during the unloading stage, which greatly facilitates the placement of the bulletproof glass to be detected, avoids the inconvenience of operation in a small enclosed space, and improves work efficiency. In addition, the through-hole design at the bottom of the movable rack 10 provides the necessary conditions for the detection and processing of the lower surface of the bulletproof glass, ensures the comprehensiveness and feasibility of the detection and processing of the upper and lower surfaces, avoids the detection blind area caused by unreasonable structure, and helps to improve the detection accuracy; in addition, through multiple driving electric cylinders 13, clamping electric cylinders 15 and clamping plates The combined design of 16 and rubber pad 17 can flexibly adjust the spacing and tightly clamp the bulletproof glass according to the size specifications. The setting of rubber pad 17 can not only ensure the stability of clamping, but also avoid damage to the glass surface. The retractable design of support block 18 is also very critical. It plays a stable supporting role for the glass during discharge, and can be reset in time during detection and cleaning to avoid interference with subsequent operations, ensuring the smoothness of the entire detection process and the efficient coordination of various links, making the detection results more accurate and reliable, and also improving the adaptability and versatility of the equipment to bulletproof glass of different specifications.

Cleaning brushes 22 are rotatably arranged on the left and right sides of the interior of the adjusting frame 20, and the two cleaning brushes 22 are driven to rotate by a motor arranged at the bottom of the adjusting frame 20. Dust suction pipes 23 are also symmetrically fixedly arranged on the left and right sides of the interior of the adjusting frame 20, and the bottom ends of the two dust suction pipes 23 are connected to the dust collecting tank arranged inside the fixed frame 19 through a dust suction pump, wherein the two cleaning brushes 22 rotate in opposite directions, and through the rotation of the two cleaning brushes 22, the dust and impurities on the surface of the bulletproof glass are cleaned to the upper ends of the two dust suction pipes 23, thereby ensuring the cleanliness of the surface of the bulletproof glass before detection.

[0033] Furthermore, an electric slide 24 is fixedly provided in the middle part of the adjusting frame 20, and a coating thickness gauge 25 is slidably provided on the top of the electric slide 24. The coating thickness gauge 25 is used to detect the coating thickness of the detection surface of the bulletproof glass to avoid the adverse effects of uneven coating or coating with poor adhesion on the accuracy of the detection result, so as to make the detection data more reliable.

[0034] In a specific embodiment, the present invention connects the fixed frame 19 and the adjusting frame 20 through a servo electric cylinder 21, and can flexibly and accurately adjust the position of the adjusting frame 20 to adapt to bullet-proof glass of different thicknesses and sizes, thereby ensuring the accuracy and comprehensiveness of cleaning and detection operations. The cleaning brush 22 rotates in the opposite direction under the drive of the motor, and cooperates with the dust suction pipe 23 and the dust suction pump to efficiently remove dust and impurities on the surface of the bullet-proof glass, thereby ensuring the cleanliness of the glass surface before detection, greatly reducing the detection error caused by surface impurities, and improving the accuracy of subsequent curvature detection. Furthermore, the coating thickness gauge 25 on the electric slide 24 can detect the coating thickness on the glass surface in time after cleaning is completed, and discover and avoid the adverse effects of uneven coatings or coatings with poor adhesion on the curvature detection results in advance, thereby ensuring the reliability and accuracy of the detection data, providing important preliminary guarantees for the entire bullet-proof glass curvature detection process, and improving the practicality of the detection equipment and the quality of the detection results.

[0035] See also Figure 2 and Figure 7 As shown, specifically, the detection unit 8 includes a shielding frame 26, and the shielding frame 26 is fixedly arranged at the top and bottom of the left side of the inside of the shielding detection frame 1, and two sliding frames 28 are slidably arranged inside the two shielding frames 26. Here, the structure of the detection unit 8 located at the lower left side of the inside of the shielding detection frame 1 is mainly described; Linear slide rails 3 27 are fixedly provided on the left and right sides inside the shielding frame 26, and the tops of the two linear slide rails 3 27 are slidably connected to the left and right sides of the bottoms of the two sliding frames 28 respectively. Electric slides 29 are fixedly provided inside the two sliding frames 28, and a plurality of linear modules 30 are slidably provided on one side of the electric slides 29. Detection heads 31 are fixedly provided on the driving ends of the plurality of linear modules 30, and the plurality of detection heads 31 provided inside the two sliding frames 28 respectively adopt capacitive displacement sensors and laser displacement sensors. Specifically, a plurality of capacitive displacement sensors are provided inside the sliding frame 28 located on the front side inside the shielding frame 26 as detection heads 31, and a plurality of laser displacement sensors are provided inside the sliding frame 28 located on the rear side inside the shielding frame 26 as detection heads 31. By comparing and analyzing the measurement results of the two groups of detection heads 31, the accuracy of the detection results of the curvature of the bulletproof glass is improved.

[0036] It should be noted that when the curvature of the bulletproof glass is detected, the driving unit 6 is used to drive the displacement of the bulletproof glass between the upper and lower shielding frames 26. At this time, the driving ends of several linear modules 30 inside one of the upper and lower sliding frames 28 are controlled to drive the detection head 31 to move to the upper and lower parts of the unloading rack 12 respectively. Infrared horizontal sensors are arranged at the upper and lower parts of the unloading rack 12. The infrared horizontal sensors are used to detect the horizontal positions of several detection heads 31 at the upper and lower parts to ensure that the positions of several detection heads 31 are unified before detection. Then, the driving ends of several linear modules 30 are used to control several detection heads 31 to approach the upper and lower surfaces of the bulletproof glass until one side of several detection heads 31 contacts the surface of the bulletproof glass. The displacement distance is recorded by several detection heads 31. By comparing the displacement distances of the detection heads 31 at several detection points, the displacement distance curves of each detection point are drawn, thereby obtaining the curvature of the bulletproof glass and completing the curvature detection operation of the bulletproof glass.

[0037] In a specific embodiment, the shielding frame 26 and the sliding frame 28 of the present invention cooperate with the linear slide rail 3 27 to provide a stable and accurate platform for the movement of the detection head 31, so that the detection head 31 can flexibly detect bullet-proof glass at different positions to meet the detection needs of glass of various shapes and sizes. The combination of the electric slide table 29 and the linear module 30 further accurately controls the displacement of the detection head 31 to achieve detailed detection of multiple points on the glass surface, improve the comprehensiveness and accuracy of the detection, and use capacitive displacement sensors and laser displacement sensors as the detection head 31, which can give full play to the advantages of both and can be used from different angles. The curvature of the glass is measured based on the degree and principle, which complement and verify each other and enhance the reliability of the test results. In addition, the horizontal position of the test head 31 is detected and calibrated using an infrared horizontal sensor, which ensures that each test head 31 is in a uniform horizontal position before testing, avoiding measurement errors caused by initial position differences, so that the final displacement distance curve can more accurately reflect the actual curvature of the bulletproof glass, greatly improving the accuracy and stability of the entire testing equipment for testing the curvature of the bulletproof glass, ensuring high-quality output of the test results, and providing strong data support for quality evaluation and production process improvement of bulletproof glass.

[0038] See also Figures 1 to 7 Specifically, this embodiment also discloses a detection method of a bulletproof glass curvature detection device, comprising the following steps: Step 1: Drive the movable frame 10 to slide to the rightmost side of the shielding detection frame 1 through two linear slide rails 1 9, at which time the right half of the movable frame 10 is outside the shielding detection frame 1, and then drive the unloading frame 12 to slide to the rightmost side of the movable frame 10 through two linear slide rails 2 11, at which time the unloading frame 12 is entirely outside the shielding detection frame 1; Step 2, put the bulletproof glass to be tested into the unloading rack 12, and control the support blocks 18 on the lower sides of the two clamping racks 14 to extend at the same time, adjust the spacing between the two clamping racks 14 according to the size of the bulletproof glass to be tested, and adjust the two clamping racks 14 to one side of the left and right sides of the bulletproof glass by controlling the extension stroke of the driving ends of the driving electric cylinders 13 on the left and right sides, put the bulletproof glass into the unloading rack 12, and use the two support blocks 18 to support the bottom of the left and right sides of the bulletproof glass. At this time, the driving ends of the several clamping electric cylinders 15 inside the two clamping racks 14 cooperate with the clamping plates 16 to push the rubber pad 17 and the left and right sides of the bulletproof glass to fit; Step 3, using two linear slide rails 9 to drive the movable frame 10 to slide into the shielding detection frame 1, at this time, the two fixed shielding plates 4 and the movable shielding plate 5 on the left and right sides cooperate with each other to temporarily close the inside of the shielding detection frame 1, and use the servo electric cylinder 21 driving end inside the two fixed frames 19 to control the upper and lower adjustment frames 20 to approach the upper and lower surfaces of the bullet-proof glass, and use the upper and lower cleaning brushes 22 to clean the dust on the upper and lower surfaces of the bullet-proof glass, and use the coating thickness gauge 25 to detect the coating thickness of the detection surface of the bullet-proof glass; Step 4, after completing the cleaning process of the upper and lower surfaces of the bullet-proof glass, the bullet-proof glass is driven to move between the upper and lower shielding frames 26 through the driving unit 6. At this time, the driving ends of several linear modules 30 inside one of the upper and lower sliding frames 28 are controlled to drive the detection head 31 to move to the upper and lower parts of the unloading rack 12 respectively. Infrared level sensors are arranged at the upper and lower parts of the unloading rack 12. The infrared level sensors are used to detect the horizontal positions of several detection heads 31 at the upper and lower parts to ensure that the positions of several detection heads 31 are unified before detection. Then, the driving ends of several linear modules 30 are used to control several detection heads 31 to approach the upper and lower surfaces of the bullet-proof glass until one side of several detection heads 31 contacts the surface of the bullet-proof glass. The displacement distance is recorded by several detection heads 31. By comparing the displacement distance of the detection head 31 at several detection points, the displacement distance curve of each detection point is drawn, thereby obtaining the curvature of the bullet-proof glass, and completing the curvature detection operation of the bullet-proof glass.
