Description

Technical Field

[0001] This invention relates to the field of automotive glass strength testing technology, specifically to a strength testing device and method for automotive glass processing. Background Technology

[0002] Glass is a typical brittle material, with tensile strength far lower than compressive strength. When cracks or defects exist on the surface or inside the glass, stress concentration and crack propagation are easily generated. Automobiles are widely used in people's lives, and automotive glass is one of the components of a car. High-strength automotive glass can effectively protect the safety of people. It is necessary to test the strength of the glass to ensure its quality.

[0003] However, existing glass testing equipment uses a pin to gradually increase pressure at the center of the glass, which is inefficient.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN220894136U discloses an insulated glass testing device, comprising a testing chamber body, a mounting frame, and a door. An outer rod is welded to the inner wall of the testing chamber body, and an inner rod is movably inserted into one side of the outer end face of the outer rod. The inner rod is fixed to one side of the outer end face of the mounting frame. A fixing pad is embedded and fixed into the inner wall of the mounting frame, and a fixing rod is welded to the upper surface of the mounting frame. A connecting rod is movably inserted into the lower surface of the fixing rod, and a pressure plate is welded to the lower surface of the connecting rod. The door hinges are connected to the front surface of the testing chamber body, and support legs are welded to the lower surface of the testing chamber body. An ultraviolet lamp is installed at the top inside the testing chamber body, and an ultraviolet sensor is installed at the bottom inside the testing chamber body. A timer is installed at the bottom inside the testing chamber body, next to the ultraviolet sensor. This invention facilitates the testing of the ultraviolet isolation intensity of insulated glass.

[0005] Furthermore, in the prior art, Chinese patent publication number CN106568663B discloses a tempered glass strength testing device, including a frame and a testing component. The testing component is mounted on the frame and includes an upper fixed plate. Guide rods are slidably connected to both ends of the lower part of the upper fixed plate. A main guide rod is fixedly connected to the middle of the upper fixed plate. A pressure rod is provided below the main guide rod. The device also includes a spring, which is sleeved on the main guide rod and the pressure rod. Additionally, it includes a cylinder, which includes a piston and a piston rod. The lower end of the piston rod is connected to the main guide rod. A space is provided between the guide rod and the main guide rod. The hydraulic cylinder includes an upper cylinder, a lower cylinder, a push plate, and a first connecting rod. One end of the first connecting rod is connected to the push plate. It also includes a deformation component. A second connecting rod is connected above the push plate and is fixedly connected to an upper fixing plate. A hydraulic airbag is provided below the test block, and a liquid guide pipe is also included. The hydraulic airbag is connected to the lower cylinder through the liquid guide pipe. When it is necessary to transport the tempered glass plate to be tested or to repair the testing device, the sliding protective device is slid to the middle of the testing device during the testing of the tempered glass plate to prevent glass breakage and splashing from causing injury to the staff.

[0006] The aforementioned device utilizes a spring to drive the support block during use, thereby improving the stability of the spring and the overall strength of the testing equipment. However, in the aforementioned device, the spring only drives the support block, and the testing equipment only performs pressure resistance testing on the glass, without performing impact testing on the glass, which affects the quality of the glass. Therefore, in actual use, the testing equipment may be relatively simple, resulting in poor glass quality during testing. Summary of the Invention

[0007] The purpose of this invention is to provide a strength testing device and method for automotive glass processing, in order to solve the problem mentioned in the background art that the limited testing equipment leads to poor glass quality.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a strength testing device and method for automotive glass processing, comprising a worktable, a collection chamber movably mounted on the top of the worktable, a support column fixedly mounted on the inner side of the worktable, a fixed seat fixedly mounted on the outer surface of the support column, a drive gear movably mounted on the outer surface of the fixed seat, and a retraction mechanism for auxiliary impact testing provided between the worktable and the fixed seat; a base fixedly mounted on the bottom surface of the worktable, the base movably abutting the bottom surface of the collection chamber, a clamping assembly fixedly mounted on the outer surface of the collection chamber, a buffer plate movably abutting the outer surface of the collection chamber, and a vibration mitigation protection mechanism provided between the worktable and the buffer plate; a stepper motor fixedly mounted on the top of the worktable, a positioning screw movably mounted on the inner side of the worktable, and a height adjustment lifting mechanism provided between the worktable and the positioning screw.

[0009] Furthermore, the protection mechanism includes a buffer spring, which is fixedly installed on the outer surface of the workbench. A buffer plate is fixedly installed on the outer surface of the buffer spring, and the buffer spring and the buffer plate form a telescopic structure.

[0010] Furthermore, an output shaft is rotatably mounted on the output end of the stepper motor, a belt is rotatably mounted on the outer surface of the output shaft, and a positioning screw is rotatably mounted on the inner side of the belt, and the belt and the positioning screw form a rotating structure.

[0011] Furthermore, the lifting mechanism includes a connecting plate, a positioning screw is threadedly installed on the inner side of the connecting plate, a support rod is fixedly installed on the outer surface of the connecting plate, a servo motor is fixedly installed at the top end of the support rod, a drive shaft is rotatably installed at the output end of the servo motor, a first bevel gear is fixedly installed on the outer surface of the drive shaft, and the positioning screw and the connecting plate form a lifting structure.

[0012] Furthermore, the first bevel gear and the second bevel gear are meshed together, a threaded rod is fixedly installed on the inner side of the second bevel gear, a sliding block is threadedly installed on the outer surface of the threaded rod, and a pressure tester is fixedly installed on the bottom surface of the sliding block.

[0013] Furthermore, a fixing sleeve is fixedly installed on the outer surface of the pressure tester, a traction rope is fixedly installed on the outer surface of the fixing sleeve, a positioning plate is fixedly installed on the outer surface of the traction rope, a first guide roller is movably abutted against the outer surface of the traction rope, connecting rods are fixedly installed on both sides of the first guide roller, the connecting rods are fixedly installed on the bottom surface of the support rod, and a second guide roller is fixedly installed on the bottom surface of the support rod.

[0014] Furthermore, a reset spring is fixedly installed on the outer surface of the positioning disk, a limit rod is movably installed on the inner side of the positioning disk, a stop is movably installed on the outer surface of the limit rod, and an impact column is movably abutted at the top of the stop.

[0015] Furthermore, the receiving and releasing mechanism includes a collecting roller, which is fixedly mounted on the outer surface of the drive gear. The drive gear is meshed with a rack, which is fixedly mounted on the outer surface of the connecting plate.

[0016] Furthermore, a storage rope is movably wound around the outer surface of the collecting roller, and the storage rope movably abuts against the outer surface of the driving roller. The driving roller is fixedly installed at the top of the support rod, the storage rope is fixedly installed on the outer surface of the impact column, and the impact column movably abuts against the inner side of the support rod.

[0017] Further, the specific steps are as follows: S1: The positioning screw is driven to rotate by starting the stepper motor. The positioning screw drives the connecting plate carrying the support rod to rise and fall, thereby facilitating the adjustment of the height of the testing equipment. The pressure tester is used to press on the car glass, thereby facilitating the testing of the strength of the car glass; S2: The lifting and lowering of the connecting plate drives the drive gear and rack to mesh and connect. The drive gear drives the collecting roller to rotate, thereby retracting and releasing the collection rope.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) Pressing with a pressure tester facilitates the testing of the compressive strength of automotive glass. The pressure tester moves the fixed sleeve, which in turn moves the traction rope. The first and second guide rollers are used to position and transmit the traction rope. The traction rope pulls the positioning plate, which in turn moves the reset spring. The positioning plate moves the stop block, and the limit rod limits the stop block, which facilitates the rapid fall of the impact column. This facilitates the diversity of testing and improves the efficiency of testing.

[0020] (2) The rack moves by lifting the connecting plate, the rack and the drive gear mesh and rotate, the drive gear drives the collecting roller to rotate, thereby releasing the collecting rope, so that the impact column falls quickly, thereby conducting impact resistance testing on the car glass.

[0021] (3) The drive roller installed by the support rod facilitates the transmission of the storage rope, thereby preventing the storage rope from falling off when the impact column falls, making it convenient to retrieve the storage rope. Furthermore, the broken glass falls into the collection chamber, making it convenient for personnel to handle.

[0022] (4) By starting the stepper motor, the stepper motor drives the output shaft to rotate, the output shaft drives the belt to rotate, the belt drives the positioning screw to rotate, the positioning screw drives the connecting plate to rise and fall, and the connecting plate drives the support rod carrying the pressure tester to rise and fall, thereby facilitating the adjustment of the height of the pressure tester;

[0023] (5) By starting the servo motor, the servo motor drives the drive shaft to rotate, the drive shaft drives the first bevel gear and the second bevel gear to mesh and rotate, the second bevel gear drives the threaded rod to rotate, the threaded rod drives the sliding block to move, and the sliding block drives the pressure tester to move, thereby facilitating the detection of different positions of the car glass and improving the accuracy of the detection.

[0024] (6) Place the car glass on the surface of the collection compartment. When the collection compartment vibrates, the buffer plate drives the buffer spring to extend and retract. The worktable fixes the buffer spring, thereby relieving the impact force and preventing the collection compartment from shifting. Attached Figure Description

[0040] By starting the stepper motor 9, the stepper motor 9 drives the output shaft 10 to rotate, the output shaft 10 drives the belt 11 to rotate, the belt 11 drives the positioning screw 12 to rotate, the positioning screw 12 drives the connecting plate 13 to rise and fall, and the connecting plate 13 drives the support rod 14 carrying the pressure tester 21 to rise and fall, thereby facilitating the adjustment of the height of the pressure tester 21.

When the car glass is placed on the surface of the collection chamber 2, when the collection chamber 2 vibrates, the buffer plate 6 drives the buffer spring 5 to extend and retract, and the worktable 1 fixes the buffer spring 5, thereby relieving the impact force and preventing the collection chamber 2 from shifting.

[0041] Example 3: Based on Example 1, please refer to... Figure 1 - Figure 10The document also discloses a stop 29, the specific structure of which is as follows: a fixed sleeve 22 is fixedly installed on the outer surface of the pressure tester 21; a traction rope 23 is fixedly installed on the outer surface of the fixed sleeve 22; a positioning plate 27 is fixedly installed on the outer surface of the traction rope 23; a first guide roller 24 is movably abutted against the outer surface of the traction rope 23; connecting rods 25 are fixedly installed on both sides of the first guide roller 24; connecting rods 25 are fixedly installed on the bottom surface of the support rod 14; a second guide roller 26 is fixedly installed on the bottom surface of the support rod 14; a reset spring 30 is fixedly installed on the outer surface of the positioning plate 27; a limit rod 28 is movably installed on the inner side of the positioning plate 27; a stop 29 is movably installed on the outer surface of the limit rod 28; and an impact column 35 is movably abutted against the top of the stop 29. The take-up and release mechanism includes a collecting roller 32, which is fixedly installed on the outer surface of the drive gear 31. The drive gear 31 and rack 33 are meshed and connected; the rack 33 is fixedly installed on the outer surface of the connecting plate 13; and the outer surface of the collecting roller 32... A storage rope 36 is movably wound around the surface of the drive roller 34, which is fixedly mounted on the top of the support rod 14. The storage rope 36 is fixedly mounted on the outer surface of the impact column 35, which is movably abutted against the inner side of the support rod 14. The specific steps are as follows: S1: The positioning screw 12 is driven to rotate by starting the stepper motor 9.

[0042] The connecting plate 13 lifts and lowers, causing the rack 33 to move. The rack 33 meshes with the drive gear 31, which in turn drives the collecting roller 32 to rotate, releasing the collecting rope 36. This allows the impact column 35 to fall quickly, thus performing an impact resistance test on the automotive glass. Furthermore, the pressure tester 21 presses the glass, facilitating a compressive strength test. The pressure tester 21 also moves the fixing sleeve 22, which in turn moves the traction rope 23. The first guide roller 24 and the second guide roller 26 are used to position the traction rope 23. The transmission mechanism involves pulling the positioning plate 27 via the traction rope 23. The positioning plate 27 then drives the return spring 30 to extend and retract, and the positioning plate 27 also moves the stop block 29. The stop block 29 is limited by the limit rod 28, which facilitates the rapid fall of the impact column 35, allowing for diverse detection methods and improving detection efficiency. The drive roller 34 installed via the support rod 14 facilitates the transmission of the collection rope 36, thus preventing the collection rope 36 from falling off when the impact column 35 falls, making it easy to retrieve the collection rope 36. Furthermore, the broken glass falls into the collection chamber 2, making it convenient for personnel to handle.
