Description

Technical Field

[0001] This invention belongs to the technical field of tempered glass testing equipment, and particularly relates to an automatic tempered glass testing device and method. Background Technology

[0002] Tempered glass, with its excellent properties of high strength, impact resistance, and high pressure resistance, is widely used in many fields such as building curtain walls, automobile windows, home appliance panels, and rail transportation. The pressure resistance of tempered glass is a core indicator for measuring its product quality and safety. Before leaving the factory, tempered glass must undergo sampling tests on different locations on its surface using professional testing equipment to check its pressure resistance limit and compressive stability, preventing substandard products from entering the market and ensuring subsequent safety.

[0003] Currently available automatic pressure resistance testing devices for tempered glass have significant shortcomings in practical use. The core issues lie in the inconvenience of adjusting the testing position and the lack of testing flexibility. Existing testing equipment typically uses a fixed installation structure with pre-fixed testing points. This prevents flexible adjustment of the testing position based on the size and specifications of the tempered glass and the requirements of testing standards. It can only perform pressure resistance testing at fixed points on the glass, making it difficult to achieve multi-point sampling testing across the entire surface. This results in incomplete testing data that fails to comprehensively reflect the overall pressure resistance performance of the tempered glass, leading to insufficient testing accuracy and completeness. Summary of the Invention

[0013] Based on the same inventive concept, this application also provides an automatic detection method for tempered glass, including the following steps:

[0014] S1. Glass clamping and positioning: Based on the size and specifications of the tempered glass to be tested, the horizontal installation position of the vertical moving seat is adjusted by the horizontal moving component on the frame, and the vertical height of the flexible clamping component is adjusted by the vertical moving component. Multiple sets of flexible clamping components are used to flexibly clamp and fix the tempered glass, completing the limit clamping of the tempered glass and avoiding glass displacement or damage from impacts during the testing process.

[0015] S2, Detection point adjustment: Based on the preset pressure resistance test points of the tempered glass to be tested, the installation positions of the first test mechanism and the second test mechanism are adjusted by sliding the slide rail seat respectively, so that the first test ball of the first test mechanism and the second test ball of the second test mechanism correspond to different test areas of the tempered glass, adapting to the multi-point test requirements of different specifications of glass.

[0016] S3. Automated pressure resistance test: The first and second testing mechanisms are controlled by the electrical control box to start the testing operation synchronously or independently. When the first testing mechanism is running, the first motor drives the first lead screw to rotate, which drives the first nut, the first guide plate and the first top shaft to move synchronously, pushing the first experimental ball to press against the tempered glass testing point at a uniform speed. At the same time, the pressure data and deformation force data of each testing point are collected in real time through the first tension sensor.

[0017] S4. Travel Limit Protection and Data Judgment: During the testing process, the first travel switch and the first toggle block work together to limit the displacement of the first testing mechanism, preventing over-travel testing from damaging the equipment or glass. The control box receives and stores the stress test data of each testing point in real time, compares it with the preset pressure resistance standard parameters, and automatically determines whether the pressure resistance performance of each testing point of the tempered glass is qualified, thus completing the fully automatic pressure resistance test of the tempered glass.

[0018] The automatic tempered glass testing device and method provided in this invention have at least one of the following technical effects:

[0019] 1. This invention features a sliding rail base with two independently sliding first and second detection mechanisms. Operators can freely adjust the horizontal position of the two detection mechanisms according to the size of the tempered glass and the requirements of the testing standards, accurately corresponding to any detection point such as the center, edge, and corner of the tempered glass. There is no need for manual disassembly and assembly of equipment or movement of glass, which greatly simplifies the operation of adjusting the detection position. It is suitable for testing tempered glass of different lengths, widths, thicknesses, and models, and its versatility is greatly improved.

[0020] 2. This invention features two independently designed testing mechanisms, allowing for simultaneous or independent testing depending on the requirements. It can perform dual-point pressure resistance testing of tempered glass in a single operation, improving batch testing efficiency; alternatively, a single testing mechanism can be activated to perform precise single-point testing. Furthermore, by adjusting the positions of the two testing mechanisms, multi-area sampling testing of the glass can be completed in one go. This solves the problems of single-point testing, incomplete data, and incomplete testing inherent in traditional equipment, effectively ensuring the integrity and accuracy of tempered glass quality testing.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0040] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0041] In one embodiment of the present invention, such as Figures 1-8 As shown, an automatic tempered glass testing device is provided, including a frame 1, an electrical control box 2, a slide rail base 3, a clamping mechanism 4, a first testing mechanism 5, and a second testing mechanism 6. The frame 1 is an integral load-bearing structure, welded from high-strength steel, with a stable structure and strong load-bearing capacity, effectively preventing equipment shaking during testing from affecting testing accuracy. The electrical control box 2 is fixed to the middle of the side of the frame 1 by bolts. It integrates a PLC control system, a power supply module, and a signal receiving module, which are electrically connected to the first motor 501, the second motor, the first tension sensor 511, the second tension sensor, the first limit switch 515, and the second limit switch through wires, realizing the overall automated control, data acquisition, and parameter adjustment of the equipment. The slide rail base 3 is horizontally fixed to the upper rear side of the frame 1, providing a sliding mounting base for the first testing mechanism 5 and the second testing mechanism 6.

[0042] The first sliding plate 500 of the first detection mechanism 5 is slidably mounted on the surface of the slide rail 3, and can slide freely horizontally left and right along the slide rail 3. After sliding to the designated detection position, it can be fixed in position by the matching locking structure to achieve precise positioning of the detection point. The first motor 501 is a servo motor, which is fastened to the center position of the lower end face of the first lower fixing plate 504 by bolts. The servo motor has high precision and controllable speed, and can accurately control the pressure stroke and pressure speed.

[0043] The first lead screw 502 is vertically arranged, and its top end is coaxially fixed to the output shaft of the first motor 501. The first lead screw 502 is threadedly connected to the first nut 503. The outer side of the first nut 503 is fixedly connected to the first guide plate 507 and the first top shaft 510 respectively. The first motor 501 can drive the lead screw to rotate by forward and reverse rotation, thereby driving the first nut 503, the first guide plate 507, and the first top shaft 510 to move up and down as a whole. Two first guide rods 505 are symmetrically fixed between the first lower fixed plate 504 and the first sliding plate 500. The first guide plate 507 has through holes corresponding to the guide rod positions, and the first guide cylinder 506 is fixed in the holes. The first guide cylinder 506 is movably sleeved on the outside of the first guide rod 505. The first guide rod 505 and the first guide cylinder 506 cooperate with each other to provide precise guidance for the lifting and lowering movement of the first guide plate 507 and the first top shaft 510, preventing deviation and jamming during the lifting and lowering process, and ensuring the verticality and stability of the pressure detection.

[0044] The first dust cover 509 is a closed shell structure, fixed to the inside of the first slide plate 500 by bolts. The first top shaft 510 vertically penetrates the central through hole of the dust cover and can freely extend and retract. The first dust cover 509 can completely cover the internal transmission components such as the first lead screw 502 and the first guide rod 505, achieving dust protection. The bottom end of the first top shaft 510 is fixed to the first tension sensor 511, and the bottom end of the first tension sensor 511 is fixed to the first experimental ball 512 with a spherical structure. The first experimental ball 512 is made of high-strength wear-resistant material and has a smooth surface, which can evenly contact the tempered glass plate surface, avoiding stress concentration that could lead to abnormal glass breakage. At the same time, the tension sensor can collect pressure data in real time during the detection process, accurately reflecting the pressure resistance performance of the tempered glass. In this device, the first experimental ball 512 can be made of industrial ceramic material, preferably zirconia ceramic or high-purity alumina ceramic. This type of precision industrial ceramic material has high hardness, minimal deformation, and a smooth, wear-resistant surface. It will not produce elastic micro-deformation during the pressure test, ensuring that the pressure is applied vertically and evenly to the tempered glass test point, effectively improving the accuracy of the pressure test data. At the same time, it will not scratch or damage the tempered glass surface, making it suitable for high-precision pressure resistance test conditions.

[0045] A vertically arranged first fixing rod 513 is fixed between the first lower fixing plate 504 and the first sliding plate 500. A first mounting base 514 is fixed in the middle of the first fixing rod 513. A first limit switch 515 is snapped onto the outside of the first mounting base 514. The first limit switch 515 is a contact limit switch. A first toggle block 516 is fixed on the side of the first guide plate 507. When the first guide plate 507 rises and falls to its limit stroke, the first toggle block 516 touches the first limit switch 515. The electrical control box 2 immediately receives the signal and controls the first motor 501 to stop, realizing over-travel limit protection and effectively avoiding equipment overload damage and glass breakage.

[0046] The second detection mechanism 6 has the following specific structure: Its overall structure is completely symmetrical to the first detection mechanism 5. It is independently assembled on the slide rail 3. The second sliding plate is slidably connected to the slide rail 3, allowing for synchronous sliding adjustment with the first detection mechanism 5, or independent sliding adjustment to achieve dual-point differential detection. The assembly and connection methods and working principles of the second motor, second lead screw, second nut, second guide rod, second guide cylinder, second guide plate, second top shaft, second tension sensor, and second experimental ball are consistent with those of the first detection mechanism 5.

[0047] The second fixing rod is vertically fixed between the second lower fixing plate and the second sliding plate. The second mounting base and the second limit switch are fixed on the outside of the second fixing rod. The second guide plate fixes the second toggle block, forming an independent limit protection structure. The two sets of detection mechanisms do not interfere with each other and operate independently. The working mode can be flexibly switched according to the detection requirements, adapting to a variety of detection scenarios.

[0048] The clamping mechanism 4 is specifically designed to securely clamp tempered glass of different sizes. It includes two symmetrically arranged transverse moving seats, two vertical moving seats 43, four sets of vertical moving components 42, and four sets of flexible clamping components 44. The two sets of transverse moving components 41 are symmetrically fixed to the upper surface of the frame 1 and are used to adjust the left and right positions of the tempered glass. Each set of transverse moving components 41 includes a transverse slide rail 411 and two transverse sliding parts. The transverse slide rail 411 is horizontally fixed to the frame 1 by bolts, and the transverse slider 412 is slidably mounted on the transverse slide rail 411 and can slide left and right along the slide rail.

[0049] A transverse locking bolt 413 is threaded onto the side of the transverse slider 412. A transverse locking handle 414 is fixed to the outer end of the transverse locking bolt 413. By rotating the transverse locking handle 414, the operator can control the transverse locking bolt 413 to tighten or loosen the transverse slide rail 411, thereby realizing the sliding adjustment and locking of the transverse slider 412, preventing it from moving left and right during the tempered glass pressure resistance test and affecting the test accuracy. Two vertical moving seats 43 are respectively fixed on the transverse slider 412 of the front and rear transverse moving components 41, and synchronously complete the transverse position adjustment with the transverse slider 412.

[0050] Two sets of vertical moving components 42 are symmetrically fixed on each vertical moving seat 43, for a total of four sets of vertical moving components 42, which are evenly distributed around the tempered glass to achieve stable clamping at multiple points. The vertical slide rail 421 of the vertical moving component 42 is fixed to the side of the vertical moving seat 43, the vertical support frame 422 is used to support the tempered glass, and the vertical slider 423 is slidably mounted on the vertical slide rail 421, and its position can be adjusted back and forth. The vertical locking bolt 424 and the vertical locking handle 425 are mounted on the side of the vertical slider 423. By rotating the handle, the height of the vertical slider 423 can be adjusted and locked, preventing the tempered glass from moving back and forth during the pressure resistance test and affecting the test accuracy.

[0051] Each set of vertical sliders 423 is fixed to a set of flexible clamping components 44 on its outer side. A clamping fixing plate 441 is horizontally fixed to the end face of the vertical slider 423. A locking bolt 442 is threaded onto the outer side of the clamping fixing plate 441. A circular flexible clamping plate 443 is fixed to the end of the locking bolt 442. The flexible clamping plate 443 is made of flexible rubber material and is wider than the vertical support frame 422. It can fit against the tempered glass sidewall over a large area, with uniform clamping force and no rigid compression damage. The clamping distance of the flexible clamping plate 443 can be finely adjusted by rotating the locking bolt 442 to accurately adapt to tempered glass of different widths, ensuring clamping stability while protecting the glass to the greatest extent.

[0052] The specific testing workflow of this device is as follows: First, based on the size and specifications of the tempered glass to be tested, the left and right positions of the vertical moving seat 43 are adjusted using the horizontal moving component 41, and the front and rear positions of the flexible clamping component 44 are adjusted using the vertical moving component 42. After adjustment, the components are locked and fixed. The tempered glass is then placed between the four sets of flexible clamping components 44, and the locking bolt 442 is rotated to complete the flexible clamping and fixing of the glass. Subsequently, according to the preset testing points, the sliding plates of the first testing mechanism 5 and the second testing mechanism 6 are manually slid to align the two sets of experimental balls with the target testing positions of the tempered glass, and the sliding plate positions are locked to complete the positioning.

[0053] The testing program is initiated via the electrical control box 2. Single-group or dual-group synchronous testing modes can be selected. The motor drives the first lead screw 502 to rotate, causing the first top shaft 510 and the first test ball 512 to slowly apply pressure upwards. The tension sensor collects pressure data in real time and transmits it to the electrical control box 2, completing the pressure resistance test. During the test, the limit switch monitors the lifting stroke in real time; overtravel triggers an immediate stop for protection. After the test is completed, the equipment automatically resets, and the operator can release the clamping mechanism 4 to remove the glass, completing a single testing operation.

[0054] Based on the same inventive concept, this application also provides an automatic detection method for tempered glass, including the following steps:

[0055] S1. Glass clamping and positioning: According to the size and specifications of the tempered glass to be tested, the horizontal installation position of the vertical moving seat 43 is adjusted by the horizontal moving component 41 on the frame 1, and the vertical height of the flexible clamping component 44 is adjusted by the vertical moving component 42. The tempered glass is flexibly clamped and fixed by multiple sets of flexible clamping components 44 to complete the limiting clamping of the tempered glass and avoid glass displacement and damage during the testing process.

[0056] S2, Detection point adjustment: Based on the preset pressure resistance test points of the tempered glass to be tested, the installation positions of the first detection mechanism 5 and the second detection mechanism 6 are adjusted by sliding the slide rail seat 3 respectively, so that the first experimental ball 512 of the first detection mechanism 5 and the second experimental ball of the second detection mechanism 6 correspond to different test areas of the tempered glass, adapting to the multi-point test requirements of different specifications of glass.

[0057] S3. Automated pressure resistance test: The first testing mechanism 5 and the second testing mechanism 6 are controlled by the electrical control box 2 to start the testing operation synchronously or independently. When the first testing mechanism 5 is running, the first motor 501 drives the first lead screw 502 to rotate, which drives the first nut 503, the first guide plate 507 and the first top shaft 510 to move synchronously, pushing the first experimental ball 512 to press against the tempered glass testing point at a uniform speed. At the same time, the first tension sensor 511 collects the pressure data and deformation force data of each testing point in real time.

[0058] S4. Travel Limit Protection and Data Judgment: During the test, the first travel switch 515 and the first toggle block 516 cooperate to limit the displacement of the first testing mechanism 5, preventing over-travel testing from causing damage to the equipment or glass. The control box 2 receives and stores the force test data of each test point in real time, compares it with the preset pressure resistance standard parameters, and automatically determines whether the pressure resistance performance of each test point of the tempered glass is qualified, thus completing the fully automatic pressure resistance test of the tempered glass.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. An automatic inspection method for tempered glass, based on the automatic inspection device for tempered glass according to any one of claims 1-8, characterized in that, Includes the following steps: S1. Glass clamping and positioning: Based on the size and specifications of the tempered glass to be tested, the horizontal installation position of the vertical moving seat is adjusted by the horizontal moving component on the frame, and the vertical height of the flexible clamping component is adjusted by the vertical moving component. Multiple sets of flexible clamping components are used to flexibly clamp and fix the tempered glass, completing the limit clamping of the tempered glass and avoiding glass displacement or damage from impacts during the testing process. S2, Detection point adjustment: Based on the preset pressure resistance test points of the tempered glass to be tested, the installation positions of the first test mechanism and the second test mechanism are adjusted by sliding the slide rail seat respectively, so that the first test ball of the first test mechanism and the second test ball of the second test mechanism correspond to different test areas of the tempered glass, adapting to the multi-point test requirements of different specifications of glass. S3. Automated pressure resistance test: The first and second testing mechanisms are controlled by the electrical control box to start the testing operation synchronously or independently. When the first testing mechanism is running, the first motor drives the first lead screw to rotate, which drives the first nut, the first guide plate and the first top shaft to move synchronously, pushing the first experimental ball to press against the tempered glass testing point at a uniform speed. At the same time, the pressure data and deformation force data of each testing point are collected in real time through the first tension sensor. S4. Travel Limit Protection and Data Judgment: During the testing process, the first travel switch and the first toggle block work together to limit the displacement of the first testing mechanism, preventing over-travel testing from damaging the equipment or glass. The control box receives and stores the stress test data of each testing point in real time, compares it with the preset pressure resistance standard parameters, and automatically determines whether the pressure resistance performance of each testing point of the tempered glass is qualified, thus completing the fully automatic pressure resistance test of the tempered glass.
