Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass detection, in particular to a tempered glass quality detection device and a detection method thereof. Background Art

[0002] Tempered glass is a safety glass that has been treated with controlled heat or chemical treatment to increase the strength of ordinary glass. The compressive stress on its surface makes it stronger and more stable than ordinary flat glass. In actual production, ordinary flat glass is heated in a furnace to near its softening temperature, where its internal stress is eliminated through deformation. The glass is then removed from the furnace and high-pressure cold air is blown onto both sides of the glass using multiple nozzles, allowing it to cool rapidly and evenly to room temperature. This type of glass is subjected to internal tension and external compression. Automotive windshields are a common example of tempered glass.

[0003] An existing patent (publication number: CN118243521A) discloses a tempered glass quality inspection device and an inspection method thereof, comprising an inspection frame, which is symmetrically structured and has two groups; a movable frame, which is mounted on the inspection frame and can adjust its position in the vertical direction, and pressure shafts are fixedly installed on both sides of the movable frame; and two groups of movable plates movably connected to the middle of the inspection frame, wherein a first lap shaft is fixedly installed on the upper side of the movable plate, and a second lap shaft is fixedly installed on the lower side of the movable plate. By means of the arranged movable plates and the pressure shafts arranged on both sides, multi-point inspection of the tempered glass can be realized. At the same time, through the arranged comparison unit, the quality evaluation of the tempered glass can be directly obtained according to the deformation performance of the tempered glass, thereby greatly improving the inspection efficiency. At the same time, using deformation to judge the quality of the tempered glass can ensure the accuracy of the inspection results.

[0004] However, the above technical solution still has certain defects. During the detection process, the pressure applied to the windshield by the above technical solution is uniform and fixed in position. In actual situations, when the car is driving, the position and angle of the windshield being hit are not fixed, and the collision point between the windshield and the foreign object is random. The above technical solution cannot simulate this randomness in actual conditions, resulting in the detection results being inconsistent with the situation in the actual use scenario, affecting the accuracy of the detection results, and the adaptability of the detection device is poor.

[0018] 1. Install the windshield

[0019] The torsion springs are twisted by flipping the two sets of upper clamping arms, and then the windshield is placed on top of the two sets of lower clamping arms.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention drives the lower clamping arm while the hydraulic rod drives the lower sliding frame to slide downward, causing the push rod to move downward. When the roller contacts the slide rail, the push rod drives the upper clamping arm to flip, so that the upper and lower clamping arms no longer clamp the windshield. As the lower clamping arm descends, the windshield is lifted by the rubber disk. Then, the roller pushes the extension rod, causing the support spring to drive the windshield to shake continuously. As a result, when the impact rod contacts the windshield downward, the contact point between the impact rod and the windshield is somewhat random, thereby simulating the scene of the vehicle windshield being accidentally hit during actual use, and testing the impact resistance of the windshield. The test result is more in line with reality.

[0026] 2. The present invention clamps the windshield with upper and lower clamping arms, then flips the lower clamping arm to rotate the windshield. During this process, the elastic force of the spring sheet pushes the sliding seat, causing the friction block to fit the rotating shaft, preventing the windshield from rotating without manual force. Furthermore, the light bar illuminates the windshield, allowing the windshield's color aberration and optical distortion to be monitored to determine whether they meet standards.

[0027] 3. The present invention limits the impact rod by means of a hook, and then uses multiple groups of impact rods to press down on the surface of the windshield, thereby testing the strength of the windshield, and can use the first piston to push air into the pressurized chamber, and use the air pressure to push the second piston, thereby accelerating the fall of the impact rod, thereby simulating the scenario when the windshield is accidentally damaged by foreign objects while the vehicle is driving, further improving the authenticity of the detection, making the detection results more in line with reality, ensuring the quality of the windshield, and being able to realize a variety of different types of detection, thereby improving the flexibility and adaptability of the detection equipment.

DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0046] The following describes an embodiment of the present invention based on its overall structure.

[0047] A tempered glass quality detection device and detection method thereof, such as Figures 1 to 12 As shown, it includes an outer frame 1, which includes a frame 101. The bottom end of the inner wall of the frame 101 is fixedly connected to two sets of slide rails 102, and the top end of the frame 101 is fixedly connected to two sets of light strips 103 located on both sides;

[0048] The bottom end of the inner wall of the frame 101 is fixedly connected to a support mechanism 2, which includes a support spring 201. The support spring 201 is located between the two sets of slide rails 102. An extension rod 202 is fixedly sleeved on the bottom end of the outer wall of the support spring 201. The end of the extension rod 202 extends above one set of slide rails 102. The end of the extension rod 202 is provided with a protrusion. The top end of the support spring 201 is fixedly connected to a bracket 203. Multiple ends of the bracket 203 are respectively fixedly connected to a set of rubber discs 204.

[0049] The inner wall of the frame 101 is slidably connected with a fixing mechanism 3, which includes two groups of lower sliding frames 301, and the side walls of each group of lower sliding frames 301 are rotatably connected to a group of rotating shafts 306, one end of the rotating shaft 306 is fixedly connected to a lower clamping arm 307, and the top end of the lower clamping arm 307 is hinged to an upper clamping arm 308, and the upper clamping arm 308 is provided with a torsion spring at the connection with the lower clamping arm 307, and the windshield 5 is clamped between the upper clamping arm 308 and the lower clamping arm 307, and the side wall of the lower clamping arm 307 is fixedly connected to a push rod 309, and the bottom end of the push rod 309 is rotatably connected to a roller 310, and the roller 310 is located just above the slide rail 102, and the bottom end of each group of lower sliding frames 301 is fixedly connected to two groups of hydraulic rods 302, and the bottom end of the hydraulic rod 302 is fixedly connected to the bottom end of the inner wall of the frame 101;

[0050] Two sets of synchronous wheels 104 are fixedly connected to the top and the bottom of the inner wall of the frame 101 respectively. The synchronous wheels 104 are located on both sides of the top and the bottom of the inner wall of the frame 101. The outer walls of the two sets of synchronous wheels 104 on the same side are provided with synchronous belts 105. Two sets of motors are fixedly connected to the top of the frame 101, and the two sides of the synchronous belt 105 are fixedly connected to the side walls of the upper sliding frame 401 and the lower sliding frame 301 respectively.

[0051] When the upper clamping arms 308 are lifted and the lower clamping arms 307 are lifted, the windshield 5 is placed on the top of the two sets of lower clamping arms 307. The upper clamping arms 308 are then slowly released to allow the torsion springs to rebound and push the upper clamping arms 308 to reset. At this time, the upper clamping arms 308 and the lower clamping arms 307 clamp the windshield 5. The lower sliding frame 301 is then pushed upward by the hydraulic rod 302 to slide upward, causing the lower sliding frame 301 to push the synchronous belt 105 to rotate, and the synchronous belt 105 pushes the upper sliding frame 401 to descend, causing the windshield 5 to contact the impact rod 404, thereby causing the impact rod 404 to apply pressure to the windshield 5, thereby detecting whether the windshield 5 can withstand the standard pressure, thereby detecting whether the strength of the windshield 5 meets the standard. At this time, the entire device is in Figure 1The hydraulic rod 302 then drives the lower sliding frame 301 to slide downward, so that the lower sliding frame 301 pushes the upper sliding frame 401 to slide upward through the synchronous belt 105. In the process of the lower sliding frame 301 sliding downward, the roller 310 contacts the slide rail 102, so that the roller 310 is blocked by the slide rail 102. At this time, the roller 310 rolls along the slide rail 102 and drives the push rod 309 to flip, so that the upper clamping arm 308 flips, thereby releasing the windshield 5. Then, as the lower sliding frame 301 continues to descend, the ground of the windshield 5 contacts the rubber plate 204. As the lower sliding frame 301 continues to descend, the windshield 5 is supported by the rubber plate 204 and separated from the lower frame. In the above process, the roller 310 keeps rolling in the slide rail 102, so that The roller 310 contacts the protrusion, and the extension rod 202 is pushed by the roller 310. During the process of the extension rod 202 being pushed, the extension rod 202 drives the support spring 201 to bend at a certain angle. After the roller 310 is separated from the extension rod 202, the support spring 201 rebounds under the action of its own elasticity and keeps shaking, thereby driving the windshield 5 above the bracket 203 to shake. The contact surface of the windshield 5 with the rubber disc 204 is the inner arc surface of the windshield 5, and the friction between the windshield 5 and the rubber disc 204 is large, so the windshield 5 and the rubber disc 204 will not shift during shaking. The continuous shaking of the windshield 5 makes the contact point between the impact rod 404 and the windshield 5 random during the subsequent impact force detection.

[0052] Please refer to Figure 5 and Figure 6 The inner wall of each group of lower sliding frames 301 is slidably connected with two groups of sliding seats 311, and the two groups of sliding seats 311 are respectively located on both sides of the rotating shaft 306. A group of friction blocks 312 are fixedly connected to the side of each group of sliding seats 311 close to the rotating shaft 306, and two groups of spring sheets 313 are fixedly connected to the end of each group of sliding seats 311 away from the friction blocks 312. The ends of the spring sheets 313 are fixedly connected to the inner wall of the lower sliding frame 301.

[0053] The light emitted by the two sets of light strips 103 at the top edge of the frame 101 is irradiated on the windshield 5, so that the chromatic aberration and optical distortion of the windshield 5 can be observed and tested. In the initial state, the windshield 5 can be flipped over so that the lower clamping arm 307 drives the rotating shaft 306 to rotate, so that the angle of the windshield 5 can be adjusted. At this time, it is convenient to observe the chromatic aberration and other indicators of the windshield 5 at different angles. The elastic force of the spring sheet 313 pushes the sliding seat 311, so that the friction block 312 fits the outer wall of the rotating shaft 306, so the rotating shaft 306 will not rotate without human push. Moreover, since multiple sets of impact rods 404 press down on the surface of the windshield 5 at the same time, the windshield 5 can be firmly in contact with the impact rods 404 when testing the strength.

[0054] Please refer to the figure in detail. The bottom end of each group of lower sliding frames 301 is fixedly connected to a group of lower pressure rods 303.

The end of the lower pressure rod 303 located inside the sleeve 305 is fixedly connected to the first piston 304. The first piston 304 is slidingly sleeved on the inner wall of the sleeve 305. The side walls of each group of sleeves 305 are connected to a group of hoses near the bottom end. The inner wall of the frame 101 is slidingly connected to the impact mechanism 4 located above the fixing mechanism 3. The impact mechanism 4 includes an upper sliding frame 401. The upper sliding frame 401 is slidingly connected The top of the upper sliding frame 401 is connected to the inner wall of the frame 101, and multiple groups of mounting holes 402 are formed through the top of each group of mounting holes 402. A group of impact rods 404 are respectively sleeved inside the inside of the impact rods 404. The outer wall of the impact rods 404 is provided with a limiting groove 405. The top of each group of impact rods 404 is respectively fixedly connected to a group of second pistons 406. The inner wall of each group of mounting holes 402 is respectively hinged with multiple groups of hooks 403. The hooks 403 are provided with torsion springs at the connection with the mounting holes 402. The multiple groups of hooks 403 surround the outside of the impact rods 404, and the ends of the hooks 403 extend to the inside of the limiting groove 405. The top of each group of hooks 403 is respectively A group of slide grooves 407 are provided, and a group of slide rods 408 are slidably sleeved on the inner wall of each group of slide grooves 407. A baffle 409 is provided above the multiple groups of hook claws 403, and the baffle 409 is sleeved on the outer wall of the multiple assembly machine rods. The two ends of the multiple groups of slide rods 408 are fixedly connected to the bottom end of the baffle 409. The top of the upper sliding frame 401 is fixedly connected with a pressurized chamber 410. The side wall of the pressurized chamber 410 is connected to the end of the two groups of hoses at the same time at the top position. The bottom end of the pressurized chamber 410 is provided with multiple groups of vents 411, and each group of vents 411 is slidably sleeved on the outer wall of a group of second pistons 406. The top of the pressurized chamber 410 is provided with One-way valve 412, the top of the pressurized chamber 410 is provided with an air inlet hole corresponding to the position of the one-way valve 412, the top of the pressurized chamber 410 is connected to a vent pipe 413 located next to the air inlet hole, the inside of the vent pipe 413 is slidably connected with a plug 414 at the connection point with the pressurized chamber 410, the top of the plug 414 is fixedly connected with a pressure relief spring 415, the top of the pressure relief spring 415 is fixedly connected with a pressure plate 416, the top of the pressure plate 416 is rotatably connected with a threaded rod 417 extending to the outside of the vent pipe 413, the threaded rod 417 is threadedly connected to the vent pipe 413, and the side wall of the vent pipe 413 is provided with multiple groups of pressure relief holes 418.

[0055] After testing the strength of the windshield 5, the hydraulic rod 302 drives the lower sliding frame 301 to slide downward, and in the process of placing the windshield 5 on the rubber disc 204, the hydraulic rod 302 drives the lower sliding frame 301 to slide downward, so that the lower pressure rod 303 pushes the first piston 304 to slide downward inside the sleeve 305, so that the air inside the sleeve 305 is pushed into the pressurized chamber 410. After the roller 310 slides over the extension rod 202, the lower sliding frame 301 continues to descend, so that the first piston 304 slides to the bottom end of the inner wall of the sleeve 305. At the same time, the lower sliding frame 301 continues to drive the upper sliding frame 401 to slide upward through the synchronous belt 105, so that the blocking piece 409 contacts the top of the inner wall of the frame 101, and as As the upper sliding frame 401 slides, the blocking piece 409 is blocked by the top of the inner wall of the frame 101, so that the sliding rod 408 cannot continue to rise, and the upper sliding frame 401 continues to drive the hook 403 to rise, so that the sliding rod 408 pushes the hook 403 to flip, so that the end of the hook 403 is separated from the limiting groove 405. At this time, the air pressure inside the pressurizing chamber 410 pushes the second piston 406 to slide downward inside the vent 411, so that the impact rod 404 and the second piston 406 slide out of the mounting hole 402, so that the impact rod 404 quickly hits the surface of the windshield 5. At this time, the windshield 5 continues to shake under the elastic force of the support spring 201, so when the impact rod 404 hits the windshield 5, the impact rod 404 and the windshield The contact position between the glass 5 is random, thereby completing the random impact test. Then the operator controls the hydraulic rod 302 to push the lower sliding frame 301 to slide upward, so that the upper sliding frame 401 slides downward. When the blocking piece 409 is separated from the top of the inner wall of the frame 101, the hydraulic rod 302 stops pushing the lower sliding frame 301. Then, multiple sets of impact rods 404 can be inserted into the mounting holes 402, so that the hook claws 403 are pushed and flipped. When the limiting groove 405 is aligned with the end of the hook claw 403, the torsion spring rebounds and pushes the end of the hook claw 403 into the limiting groove 405, so that the impact rod 404 cannot fall. At this time, the second piston 406 slides into the vent hole 411, and then the tested windshield 5 is taken off the rubber disc 204. Then control the hydraulic rod 302 to push the lower sliding frame 301 up to its initial position, and in the process of the lower sliding frame 301 returning to its initial position, drive the lower pressure rod 303 to reset the first piston 304, thereby resetting the sleeve 305. At this time, the one-way valve 412 opens, allowing outside air to enter the pressurized chamber 410, and in the process of the first piston 304 pushing the air into the pressurized chamber 410, if the pressure exceeds the preset value, the air pressure inside the pressurized chamber 410 will push the plug 414 to slide upward and compress the pressure relief spring 415, so that the excess air inside the pressurized chamber 410 can be discharged through the pressure relief hole 418 on the side wall of the vent pipe 413, avoiding excessive pressure inside the pressurized chamber 410. By rotating the threaded rod 417,The threaded rod 417 pushes the pressure plate 416, causing the pressure plate 416 to compress the pressure relief spring 415, thereby increasing the preset pressure value. The threaded rod 417 is rotated in the opposite direction, causing the pressure plate 416 to release the pressure relief spring 415, thereby reducing the preset pressure value.

[0056] When using, 1. Place the windshield 5

[0057] The two sets of upper clamping arms 308 are flipped to twist the torsion springs, and then the windshield 5 is placed on top of the two sets of lower clamping arms 307. The upper clamping arms 308 are then released, so that the torsion springs rebound and drive the upper clamping arms 308 to press against the upper surface of the windshield 5.

[0058] 2. Compression test

[0059] The hydraulic rod 302 drives the lower sliding frame 301 to slide upward, so that the lower sliding frame 301 pushes the upper sliding frame 401 to slide downward through the synchronous belt 105, so that the impact rod 404 presses on the upper surface of the windshield 5, exerting downward pressure on the windshield 5 to test the pressure resistance of the windshield 5;

[0060] 3. Random shock test

[0061] The hydraulic rod 302 drives the lower sliding frame 301 to slide downward, so that the windshield 5 is placed on multiple sets of rubber discs 204, and the extension rod 202 is moved to make the support spring 201 shake continuously, and then the air pressure inside the pressurized chamber 410 pushes the impact rod 404 downward to impact the surface of the windshield 5.
