Description

Technical Field

[0001] This application relates to the technical field of glass testing, and more specifically, to a quality testing device for laminated safety glass. Background Technology

[0002] Laminated glass, as an important safety material, is widely used in building curtain walls, automobile windshields, and high-speed rail windows. Its core safety performance—impact resistance—must be verified through rigorous standardized testing. Currently, the industry's testing of the impact resistance of laminated glass mainly relies on traditional impact testing equipment, which has several technical shortcomings in its basic principles, structural design, and practical applications that urgently need to be addressed.

[0003] The current mainstream impact testing equipment is mainly based on two classical physical principles: free fall and pendulum. The free fall type lifts a standard mass impactor (such as a steel ball) to a preset height and then releases it, using gravitational potential energy to convert into kinetic energy to impact the specimen. The pendulum type, on the other hand, attaches the impactor to the end of the pendulum rope, and lifts the pendulum to a certain angle and then releases it, using gravitational potential energy to drive the pendulum to impact the specimen.

[0004] However, the inventors recognized that both of the above methods rely on gravitational potential energy as the sole energy source, and their energy release process is an uncontrollable uniform acceleration process. This cannot simulate the mechanical characteristics of certain instantaneous high-speed impacts in real life (such as flying stones and hail). Furthermore, the release process of the impactor is easily affected by guide rail friction, air resistance, and instantaneous disturbances of the release mechanism, resulting in its falling trajectory not being an ideal free fall, which will cause the impactor's landing point to deviate.

[0005] To address the aforementioned issues, we provide a quality testing device for laminated safety glass. Summary of the Invention

[0006] To address the problems mentioned in the background art, this application provides a device for testing the quality of laminated safety glass.

[0007] The laminated safety glass quality testing device provided in this application adopts the following technical solution:

[0008] A quality inspection device for laminated safety glass, comprising:

[0014] A support frame, located below the rotation trajectory of the swing arm, is used to position and fix the laminated glass to be tested;

[0015] The spring serves as a power source, storing energy and driving the main shaft to accelerate instantaneously upon release via a one-way transmission assembly.

[0016] In some embodiments, the power storage and acceleration mechanism includes a driving wheel that meshes with the driven wheel;

[0017] The drive wheel is connected to a drive shaft, which is rotatably mounted through the spring barrel and extends to the outside of the outer bracket, and its outer end is connected to a crank handle.

[0018] The inner end of the spring is fixed to the drive shaft, and the outer end is fixed to the inner wall of the spring box.

[0019] In some embodiments, the one-way drive assembly includes a ratchet gear ring fixedly fitted on the inner ring of the driven wheel, and a bushing coaxially fitted on the end of the main shaft;

[0020] The bushing and the driven wheel are rotatably coupled, and the outer circumferential surface of the bushing is provided with a plurality of inner grooves. At least one of the inner grooves is provided with a radially movable pawl. The pawl is biased by an elastic element to engage with the ratchet gear ring, so that the driven wheel can only drive the bushing and the main shaft to rotate in one direction.

[0021] In some embodiments, the one-way transmission assembly is provided at both ends of the spindle, and the one-way transmission assemblies at both ends allow the same driving direction.

[0022] In some embodiments, the swing arm is provided with a cross-shaped groove, which extends along the front-back and left-right directions of the swing arm. A slide block is also slidably installed in the cross-shaped groove, and the impact member passes through the slide block.

[0023] The slide block is also provided with limiting bolts that pass through the impact member. The two ends of the limiting bolts pass through the left and right sides of the cross-shaped slide groove and are fixed by nuts.

[0024] In some embodiments, a clamp is fixed to the main shaft, and the swing arm is fixed to one side of the clamp;

[0025] A tail arm is also fixed to the clamp, the extension direction of the tail arm is opposite to that of the swing arm, and a counterweight is provided on the tail arm.

[0026] The outer support is also equipped with a horizontally positioned support rod, and the swing arm can be tilted upwards and rest on the support rod to maintain stability.

[0027] In some embodiments, a bearing bracket is also fitted at the end of the extension shaft near the main shaft, and the base of the bearing bracket is fixedly installed on the inner side of the outer bracket. A telescopic connector is also provided between the extension shaft and the main shaft.

[0028] Inner bearings are also installed at both ends of the main shaft, and the inner bearings are inserted into the extension shaft and maintain a rotatable connection.

[0029] In some embodiments, the telescopic connector includes a square groove formed at the junction of the end face of the main shaft and the end face of the extension shaft, a square block is slidably disposed in the square groove, and a spring is disposed between the square block and the bottom of the square groove inside the main shaft;

[0030] The side of the spindle is provided with a radial groove that communicates with the square groove. A dial is connected to the square, and the dial passes through the radial groove and extends to the outside of the spindle.

[0031] In some embodiments, the support frame includes a pair of L-shaped frames, the inner sides of which are provided with grooves for supporting the edges of the laminated glass;

[0032] The support frame also includes an angle-adjustable side plate, and the horizontal end of the L-shaped frame is rotatably connected to the angle-adjustable side plate;

[0033] An arc-shaped groove is provided on the angle adjustment side plate. The center of the arc-shaped groove coincides with the axis of the horizontal section of the L-shaped frame. An adjustment bolt is connected to the vertical section of the L-shaped frame. The end of the adjustment bolt extends into the arc-shaped groove and is locked with a nut.

[0034] In some embodiments, a guide rail is provided below the support frame, and the angle adjustment side plate is slidably mounted on the guide rail;

[0035] A lead screw is installed inside the guide rail, and the angle adjustment side plate is threadedly engaged with the lead screw.

[0036] In summary, the technical solution of this application adopts a rotating swing arm impact method. The impactor is rigidly connected to the swing arm, and its motion trajectory is uniquely determined by the rotation of the main shaft, which can ensure the accuracy of the impact point and accurately measure the impact value at each position of the glass specimen. In addition, the spring in the power storage and acceleration mechanism can store the slowly input energy in a high density and release it instantly through the ratchet mechanism, driving the swing arm to reach the preset high speed in a very short time. This facilitates the simulation of various impact situations and meets the testing requirements of different standards or scenarios.

[0037] In the technical solution of this application embodiment, the clever cooperation of the unidirectional transmission components symmetrically arranged on both sides of the main shaft is also utilized. When the impact rebounds, the ratchet mechanism on the non-drive side transmits the rebound kinetic energy in the opposite direction to its spring. The stiffness of the spring generates a strong damping torque, thereby quickly and smoothly absorbing and dissipating the rebound energy, so that the swing arm stops quickly, which can greatly improve the operational safety and equipment stability.

[0051] The following is in conjunction with the appendix Figures 1 to 9 The present invention will be described in further detail below.

[0052] In the description of this application, it should be understood that the terms "thickness," "upper," "top," "bottom," "inner," "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0054] In related technologies, when an impactor is launched to impact laminated glass using gravitational potential energy as the sole energy source, the energy release process is an uncontrollable uniform acceleration process. This cannot simulate the mechanical characteristics of certain instantaneous high-speed impacts in real life (such as flying stones or hail). Furthermore, the release process of the impactor is easily affected by guide rail friction, air resistance, and instantaneous disturbances in the release mechanism, resulting in a non-ideal free fall trajectory and causing deviations in the impactor's landing point.

[0055] Reference Figure 1 , Figure 2 As shown, the glass quality testing device of this application mainly includes: an outer support 1, a main shaft 2 and a power storage and acceleration mechanism 204, a one-way transmission assembly and a support frame 4;

[0056] In this embodiment, the outer support 1 is the load-bearing and installation foundation of the entire device. It is usually made of sturdy steel welded or bolted to form a stable three-dimensional frame with enough space inside to accommodate the rotation of the main shaft 2 and ensure that the swing arm 3 has complete rotation space.

[0057] Specifically, a support rod 101 is also installed in the outer support 1. The support rod 101 is located at the rear of the top of the main shaft 2. After the swing arm 3 is flipped upward, it can rest on the support rod 101 to temporarily support the swing arm 3. At the same time, it can ensure that the starting position of the swing arm 3 is the same.

[0058] Reference Figure 2 , Figure 3 , Figure 7 As shown in the embodiment of this application, the main shaft 2 serves as the core transmission shaft. Its two ends are not directly supported on the outer bracket 1, but are each connected to an extension shaft 202. The extension shaft 202 is installed in the outer bracket 1 through a bearing bracket 203 at the end near the main shaft 2, which can ensure the stability of the main shaft 2.

[0059] In addition, the swing arm 3 is fixedly connected to the middle position of the main shaft 2 by the clamp 201, and can rotate downward with the main shaft 2. An adjustable impact member 301 is provided on the swing arm 3.

[0060] Specifically, the impactor 301 is usually a metal hammer with a specific mass and a specific head shape, such as a hemispherical or conical shape. By adjusting the radial position of the impactor 301 on the swing arm 3, its rotation radius can be changed, thereby controlling the position of the impactor 301 striking the test glass.

[0061] In this embodiment, the swing arm 3 is essentially a rigid arm, with its length being much greater than its width and thickness, to ensure that it has sufficient bending stiffness and will not undergo significant elastic deformation during high-speed rotation, thus affecting the impact accuracy.

[0062] In this embodiment of the application, the core of the power storage acceleration mechanism 204 is the mainspring box 2044 and the mainspring spring 2045 inside it. The mainspring spring 2045 is a coiled strip spring with a huge elastic potential energy storage capacity.

[0063] Specifically, a drive shaft 2043 is fixedly connected to the central shaft of the drive wheel 2042. One end of the drive shaft 2043 extends to the outside of the outer bracket 1 and is equipped with a rocker arm 2046. The drive shaft 2043 rotates through the mainspring box 2044, and its connection can be made by bearings. The mainspring spring 2045 located inside the mainspring box 2044 has its outer end fixed to the inner wall of the mainspring box 2044 by screws or welding, and its inner end fixed to the drive shaft 2043.

[0064] When in use, the operator turns the crank 2046 clockwise, which drives the drive shaft 2043 to rotate. Since the inner end of the spring 2045 is fixed on the drive shaft 2043 and the outer end is fixed on the inner wall of the stationary spring box 2044, the rotation of the crank will cause the spring 2045 to be wound up, and the work done by the operator will be converted into the elastic potential energy of the spring 2045 and stored.

[0065] The driving wheel 2042 is engaged with a larger driven wheel 2041, forming a first-stage gear reduction and torque amplification mechanism. When the spring 2045 has a tendency to release, its torque is transmitted to the driving wheel 2042 through the driving shaft 2043, which then drives the driven wheel 2041 to rotate, and then drives the main shaft 2 to rotate instantaneously through the one-way transmission component.

[0066] Reference Figure 5 , Figure 9 As shown in the embodiment of this application, the one-way transmission component is disposed inside the driven wheel 2041, which includes a ratchet gear ring 2047 fixed to the inner ring of the driven wheel 2041 by interference fit or screws, and a bushing 2048 coaxially sleeved on the end of the main shaft 2 and fixed by bolts. The bushing 2048 rotates and fits against the inner ring of the driven wheel 2041.

[0067] Specifically, the bushing 2048 is provided with a variable cross section, the diameter of which is smaller than the diameter of the inner ring of the driven wheel 2041. A ratchet gear ring 2047 is installed in the inner wall of the driven wheel 2041 that overlaps with the variable cross section. Correspondingly, several inner grooves 2049 are machined on the outer circumferential surface of the variable cross section. A pawl 20410 and an elastic element 20411 are respectively hinged in the inner grooves 2049 by two pins. The elastic element 20411 has a sheet-like structure and acts on the pawl 20410, so that its tail is always subjected to an outward biasing force, thereby making its head tend to bite into the tooth groove of the ratchet gear ring 2047.

[0068] During operation, when the operator turns the crank handle 2046 to wind the crank, the drive wheel 2042 is driven to rotate clockwise, and the driven wheel 2041 will rotate counterclockwise. At this time, the pawl 20410 slides on the tooth surface of the ratchet ring 2047 and makes a "click" sound. The bushing 2048 and the main shaft 2 are not driven, i.e., "free-spinning". At this time, the swing arm 3 can stay in any position. When the spring 2045 has finished storing energy and the crank handle 2046 is released, the spring 2045 will drive the driven wheel 2041 to rotate clockwise at high speed. At this time, the pawl 20410 quickly engages into the tooth groove of the clockwise rotating ratchet ring 2047 under the action of the elastic element 20411, realizing "engagement". The rotational power of the driven wheel 2041 is instantly transmitted to the main shaft 2 through the bushing 2048, driving the swing arm 3 and the impact element 301 to swing down at high speed to complete the impact.

[0069] Reference Figure 2 , Figure 3 As shown in the embodiment of this application, both ends of the spindle 2 are provided with the one-way transmission assembly, and the driving directions allowed by the one-way transmission assemblies at both ends are set to be consistent.

[0070] During operation, the operator only needs to operate the crank 2046 on one side to wind and store energy in the spring 2045 on the same side. When released, the spring 2045 on that side, which has been fully charged, drives its driving wheel 2042 and driven wheel 2041 to rotate. Due to the directional transmission characteristics of the one-way transmission component, the rotating driven wheel 2041, through the meshing of the ratchet ring 2047 and the pawl 20410, pushes the bushing 2048 and the main shaft 2 on the same side to accelerate instantaneously along the impact direction.

[0071] At this time, on the other side of the main shaft 2 (non-upper chord side), the main shaft 2 is driven to rotate in the impact direction. The pawl 20410 on the bushing 2048 on this side is in a "slipping" state with the ratchet gear ring 2047, that is, the driven wheel 2041 is spinning in this direction without generating drive or resistance.

[0072] When the impact component 301 at the end of the swing arm 3 strikes the sample glass, the huge reaction force will cause the swing arm 3 to tend to bounce back in the opposite direction, attempting to drive the main shaft 2 to rotate in the opposite direction. At this time, the working state of the one-way transmission components at both ends of the main shaft 2 immediately changes:

[0073] Drive side: The counterclockwise rotation trend of the main shaft 2 means that the pawl 20410 on the bushing 2048 on this side continues to mesh with the ratchet gear ring 2047, and the rebound force is offset by the remaining potential energy conversion of the spring spring 2045.

[0074] Non-driving side (idling side): The counterclockwise rotation of the main shaft 2 precisely satisfies the transmission conditions of the one-way transmission component on this side. The pawl 20410 on the bushing 2048 on this side quickly engages with the ratchet gear ring 2047, thereby transmitting the counterclockwise rotation power of the main shaft 2 in the opposite direction to the spring spring 2045 on this side through the gear pair between the driven wheel 2041 and the driving wheel 2042.

[0075] This reverse transmission forces the spindle of the spring 2045 to twist in the opposite direction. Since the spring 2045 itself has stiffness to resist deformation, this reverse twist immediately generates a strong damping torque. This damping torque is fed back to the main shaft 2 through the gear system, effectively suppressing and absorbing the rebound kinetic energy of the swing arm 3, thereby quickly restraining the rebound of the swing arm 3 and bringing it to a smooth stop.

[0076] Based on the above, in order to achieve adjustable position of the impact component 301, refer to Figures 1 to 3 , Figure 8 As shown, a cross-shaped through groove is provided on the front and rear sides and the left and right sides of the swing arm 3. A T-shaped slide block 302 is nested in the cross-shaped groove and can slide along the length of the groove (i.e., the radial direction of the swing arm).

[0077] Specifically, the hammer rod of the impact member 301 passes through the central hole of the slide 302. In order to lock the position, a limiting bolt 303 is provided through the slide 302 on both sides. The bolt also passes through the radial hole on the hammer rod of the impact member 301. When the impact member 301 slides to the predetermined position (a scale can be provided on the swing arm next to this position), tighten the nuts at both ends of the limiting bolt 303. The slide 302 and the impact member 301 can be locked together on the swing arm 3 by friction.

[0078] Furthermore, to ensure the dynamic balance of the spindle 2 during high-speed rotation and to avoid severe vibration caused by changes in the position of the impact component 301 or manufacturing errors, refer to Figure 3 As shown, a tail arm 304 is fixedly installed symmetrically about the swing arm 3 on the clamp 201 of the main shaft 2. The extension direction of the tail arm 304 is opposite to that of the swing arm 3.

[0079] Specifically, a mounting hole is provided on the tail arm 304, and a bolt rod is inserted through the mounting hole. Counterweights 305 can be fitted on both ends of the bolt rod. By adjusting the total mass of the counterweights 305 on the tail arm 304, the center of mass of the entire rotating system (main shaft 2, clamp 201, swing arm 3, impact component 301, tail arm 304, counterweights 305) can be returned to the axis of the main shaft 2, achieving perfect dynamic balance.

[0080] Furthermore, in order to facilitate the rotation of the swing arm 3 back to its initial position and rest it against the support pole 101 after the impact test, refer to... Figure 3 , Figure 6 As shown, both ends of the main shaft 2 extend into the inner hole of the extension shaft 202 and are rotatably connected through the inner bearing 2021;

[0081] The key is that an aligned square groove 2022 is milled together on the end face of the spindle 2 and the end face of the opposite extension shaft 202. A matching block 2023 is slidably installed in this square groove 2022, and a spring 2024 is installed between the block 2023 and the bottom of the square groove 2022 at the end of the spindle 2.

[0082] In its natural state, the spring 2024 pushes the block 2023 outward, causing it to simultaneously lock into the square groove 2022 of the main shaft 2 and the extension shaft 202, thereby locking the rotational motion of both synchronously and realizing torque transmission.

[0083] When it is necessary to flip the main shaft 2 to flip the swing arm 3 upward and reset it, the operator can press the lever 2025 on the side of the main shaft 2. The lever 2025 is fixed to the block 2023 by welding and extends through the radial groove opened on the side of the main shaft 2. The lever 2025 will drive the block 2023 to move into the main shaft 2 against the spring force until it completely exits the square groove of the extension shaft 202. At this time, the main shaft 2 and the extension shaft 202 are decoupled in the rotation direction and can rotate freely until the swing arm 3 is flipped to the initial position. Then, release the lever 2025, and the spring 2024 pushes the block 2023 to reset. If the square groove 2022 is realigned, the block 2023 will automatically spring back and reconnect.

[0084] In this embodiment, the square groove 2022 can also be configured as a non-circular groove such as a rectangular groove or a spline groove.

[0085] Reference Figure 2 , Figure 4 As shown, in this embodiment, the support frame 4 is positioned below the rotation trajectory of the swing arm 3, and its core function is to accurately position and securely clamp the sample glass.

[0086] Specifically, the support frame 4 is usually used in pairs to support the sample glass from both sides. It includes an L-shaped frame body with a clamping groove 404 on the vertical inner side of the L-shaped frame body. The width and depth of the clamping groove 404 are designed to reliably support the edge of the sample glass while avoiding additional constraints on the main impact area of ​​the sample glass.

[0087] Based on this, the horizontal section of the L-shaped frame is hinged to the angle adjustment side plate 401 via a pivot. On the angle adjustment side plate 401, an arc-shaped groove 402 is precisely machined with the pivot as the center. On the outside of the vertical section of the L-shaped frame, an adjustment bolt 403 is fixed, with its end extending into the arc-shaped groove 402.

[0088] When it is necessary to adjust the angle of the supporting glass sample, first loosen the nut on the adjusting bolt 403, and then manually rotate or use a tool to finely adjust the L-shaped frame to the required tilt angle. At this time, the end of the adjusting bolt 403 slides in the arc groove 402. After the adjustment is in place, tighten the nut again. The nut and the surface of the angle adjustment side plate 401 generate friction, thereby firmly locking the entire L-shaped frame at the set angle.

[0089] To accommodate sample glass of different widths or to precisely adjust the lateral position of the impact point, the L-shaped frame in the support frame 4 also has a horizontal movement function. Below the angle adjustment side plate 401, a guide rail 405 (such as a linear slide rail) is installed. The bottom of the angle adjustment side plate 401 cooperates with the guide rail 405 through a slider. In addition, a lead screw 406 is installed inside the guide rail 405. One end of the lead screw 406 is equipped with a handwheel. The bottom of the angle adjustment side plate 401 and the lead screw 406 are connected by threads (for example, a nut is embedded in the angle adjustment side plate 401) to form a transmission.

[0090] In use, turning the handwheel drives the lead screw 406 to rotate, which in turn drives the angle adjustment side plate 401 and the L-shaped frame on it to move laterally along the guide rail 405 precisely and smoothly, thereby aligning the preset impact point of the glass sample precisely with the tangent point of the swing arm's rotation circumference.
