Description

Technical Field

[0001] This invention relates to the technical field of glass testing, specifically to an impact testing device used in glass manufacturing. Background Technology

[0002] During the glass manufacturing process, due to uneven melting of raw materials, abnormal stress distribution during cooling, or minor defects in production equipment, internal damage such as bubbles, stones, and microcracks that cannot be observed with the naked eye can easily form inside the glass. These defects can significantly reduce the structural strength of the glass, making it prone to breakage during subsequent processing, transportation, or use, and in severe cases, can even lead to safety accidents. Therefore, after the glass is produced, it is necessary to test and screen the glass for its impact resistance and internal defects.

[0003] An impact resistance testing device for glass described in the prior art includes: a test ball, a first drive motor; a horizontal platform on a worktable for positioning and fixing the glass to be tested; a shaft fixedly mounted on the worktable; a lower plate mounted on the shaft and arranged coaxially with the shaft, the lower plate having a first vertical hole through which the weight of the test ball can pass; an upper plate mounted on the shaft and rotatable coaxially with the shaft, the upper plate being located above the lower plate, the upper plate having a second vertical hole through which the weight of the test ball can pass.

[0004] While the aforementioned technology facilitates material loading by having the test ball fall under its own weight to impact the glass under test, and ensures the accuracy of the test results by having the impact point of the test ball coincide with the test point under the limiting effect of the second vertical hole, it lacks a fully automatic recycling structure for the test ball. In three working conditions—glass rebounding intact, broken and stuck ball, and shattered ball penetrating through the glass—the test balls must be manually picked up and reset one by one. In addition, the fragments are mixed with the iron ball, and there is a risk of being scratched by small glass fragments when cleaning manually. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an impact testing device for glass manufacturing, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An impact testing device for glass manufacturing includes a testing box and an iron ball. A lifting box and a protective box are respectively installed on the two outer walls of the testing box. A perforated partition is fixed to the bottom of the testing box. A pull-out collection box is located below the perforated partition. A U-shaped fixing frame for mounting the glass to be tested is horizontally arranged above the perforated partition. A horizontal plate is located above the U-shaped fixing frame. A guide groove for supporting the iron ball is formed on the upper surface of the horizontal plate. One end of the horizontal plate is fixedly connected to the inner wall of the testing box, and the other end of the horizontal plate is located at the center of the U-shaped fixing frame and has an arc-shaped groove. The protective box and the detection box are equipped with a motion component for releasing the iron ball. The motion component can also be used to assist the iron ball in resetting after impact. A hydraulic cylinder is installed at the bottom of the lifting box. A fixed plate is installed on the top of the hydraulic cylinder inside the lifting box. A lifting plate for moving the iron ball is provided above the fixed plate. The walls of the detection box and the lifting box are respectively provided with a first through hole and a second through hole at the hollow partition and the horizontal plate.

[0007] Specifically, the inner wall of the U-shaped fixing frame is provided with a snap-fit ​​groove, and the groove wall is bonded with an anti-slip rubber pad. Multiple support plates are fixed at the bottom of the U-shaped fixing frame, and the side of each support plate away from the wall of the detection box is set as a triangular face.

[0008] Specifically, the U-shaped fixing frame has an abutment plate at its opening, and positioning plates are fixed at both ends of the abutment plate. Positioning grooves are opened on both sides of the U-shaped fixing frame corresponding to the positioning plates. A soft pad is glued to the side of the abutment plate facing the opening of the U-shaped fixing frame. Both positioning plates are detachably fixed in the positioning grooves by screws.

[0009] Specifically, in this technical solution, a reinforcing plate is fixed at the connection between the lower surface of the horizontal plate and the detection box, and a vertical guide tube is fixed at the arc groove on the lower surface of the horizontal plate, the inner diameter of which is larger than the diameter of the iron ball.

[0010] Specifically, in this technical solution, triangular guide plates are fixed on both sides of the second through hole on the inner top wall of the lifting box, the telescopic end of the hydraulic cylinder passes through the fixed plate and is fixedly connected to the lower surface of the lifting plate, and the outer wall of the lifting plate slides in contact with the inner wall of the lifting box.

[0011] Specifically, in this technical solution, triangular guide blocks are fixed on both sides of the first through hole on the upper surface of the hollow partition plate, and the outer walls of the two triangular guide blocks are in contact with the inner wall of the detection box.

[0012] Specifically, in this technical solution, the upper surfaces of the hollow partition, the lifting plate, and the horizontal plate are all set as inclined slopes, and the inclination angle of the lifting plate is smaller than the inclination angle of the hollow partition.

[0013] Specifically, the motion component includes a drive motor and a protective box. The drive motor is bolted to the top of the inner wall of the protective box, and the protective box is bolted to the top of the inner wall of the detection box. A magnetic coupler is installed inside the protective box. The output end of the drive motor passes through the walls of the detection box and the protective box and is coaxially and fixedly connected to the input end of the magnetic coupler. The output end of the magnetic coupler is connected to a first lead screw, and the end of the first lead screw passes through the wall of the protective box and is rotatably connected to the inner wall of the detection box. The first lead screw has parallel first guide rods on both sides. A movable plate is installed on the first lead screw and the two first guide rods. A baffle is fixed at the bottom of the movable plate. The baffle matches the end of the horizontal plate. A pressure sensor is embedded in the outer wall of the protective box facing the movable plate.

[0014] Specifically, in this technical solution, a rotating shaft is rotatably installed at the bottom of the protective box. Both the rotating shaft and the outer wall of the output end of the drive motor are fixed with sprockets. The two sprockets are connected by a transmission chain. The detection box is provided with a second lead screw and a second guide rod on both sides above the U-shaped fixed frame. One end of the second lead screw passes through the detection box and is fixedly connected to the rotating shaft. The other end of the second lead screw is rotatably connected to the inner wall of the detection box. Both ends of the second guide rod are fixedly connected to the inner wall of the detection box. Push plates are installed on the second lead screw and the second guide rod. The lower surface of the push plate is flush with the upper surface of the U-shaped fixed frame.

[0015] Specifically, in this technical solution, two transparent sealing doors are hinged at the opening of the testing box, and buffer pads are adhered to the inner sidewalls of both transparent sealing doors.

[0016] In summary, the present invention has the following main beneficial effects: The motion components work in conjunction with the lifting box to achieve fully automatic cyclic reset of the iron balls. Regardless of whether the glass to be tested bounces back intact, is damaged and stuck, or is broken and passes through the ball after testing, the iron balls can be automatically recovered and fed, forming an automatic closed-loop cycle of iron ball delivery, impact, and recovery. There is no need for manual picking and resetting of each ball, which reduces the safety risks caused by manual intervention. The combination of a perforated partition and a pull-out collection box enables the classification, collection, and convenient cleaning of broken glass fragments. Small fragments generated by the glass impact can naturally sink through the perforated gaps of the partition to the pull-out collection box below for centralized collection, while larger fragments remain on the upper surface of the perforated partition. After the inspection is completed, the operator only needs to perform two cleaning operations: pull out the collection box to empty the small fragments, and quickly sweep away the large fragments remaining on the surface of the perforated partition. Furthermore, the sieving function of the perforated partition facilitates an auxiliary assessment of the glass's impact resistance. The degree of glass fragmentation after being struck by an iron ball is directly related to its internal stress state and structural strength. Generally, glass with poor impact resistance fragments more thoroughly, producing more numerous and smaller fragments; while glass with better impact resistance fragments larger and with a more concentrated particle size distribution. The perforated partition physically separates small fragments from large fragments. Operators can observe the accumulation of small fragments in the collection box and the size distribution of large fragments on the partition surface to preliminarily determine the glass's impact resistance. Simultaneously, as the iron ball rolls along the inclined surface of the perforated partition, the residue adhering to its surface falls off under the action of rolling friction and impact vibration, and falls into the collection box through the mesh. In addition, the guide tube can limit and guide the falling iron ball, preventing it from deviating during its descent, further ensuring the accuracy of the impact point and improving the reliability of the test results.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] It should be noted that all electrical components within the device are controlled uniformly by an external controller.

[0022] In this embodiment, please refer to Figure 1 - Figure 8 As shown, an impact testing device for glass manufacturing includes a testing box 1 and an iron ball 7. A lifting box 2 and a protective box 5 are respectively installed on the outer walls of both sides of the testing box 1. Two transparent sealing doors 102 are hinged at the opening of the testing box 1. The inner side walls of the two transparent sealing doors 102 are glued with buffer pads. After the doors are closed, the testing chamber can be sealed and dustproof, and the external airflow can be isolated from disturbing the falling trajectory of the iron ball 7. The door can also buffer the impact force of closing the door and prevent the door from hitting the box body and deforming it. A perforated partition 101 is fixed to the bottom of the test box 1. The perforated partition 101 is made of stainless steel sheet by one-piece stamping. The plate body is evenly distributed with perforated slag channels. Triangular guide blocks 106 are fixed on both sides of the first through hole 104 on the upper surface of the perforated partition 101. The outer walls of the two triangular guide blocks 106 are in contact with the inner wall of the test box 1, which can prevent the iron ball 7 from getting stuck in the assembly gap between the side wall of the box and the partition when it rolls down. A collection box 103 that can be pulled out is provided below the perforated partition 101. A handle extends outward from the front end of the collection box 103, which is convenient to pull out and pour out the broken glass residue after the test. A U-shaped fixing frame 3 for mounting the glass to be tested is horizontally arranged above the hollow partition 101. A horizontal plate 4 is provided above the U-shaped fixing frame 3. A guide groove 401 for supporting the iron ball 7 is opened on the upper surface of the horizontal plate 4. The width of the guide groove 401 is adapted to the outer diameter of the iron ball 7, serving as a limiting rolling channel for the iron ball 7 after resetting. One end of the horizontal plate 4 is fixedly connected to the inner wall of the test box 1. The other end of the horizontal plate 4 is located at the center of the U-shaped fixing frame 3 and has an arc groove 403. A vertical guide tube 404 is fixed on the lower surface of the horizontal plate 4 at the arc groove 403. The inner diameter of the guide tube 404 is larger than the diameter of the iron ball 7, ensuring that the iron ball 7 falls vertically without jamming and impacts the glass to be tested. A reinforcing plate 402 is fixed at the connection between the lower surface of the horizontal plate 4 and the test box 1 to strengthen the bending resistance of the suspended section of the horizontal plate 4 and prevent bending deformation caused by long-term impact of falling material. The protective box 5 and the detection box 1 are equipped with a motion component 6 for releasing the iron ball 7. The motion component 6 can also be used to assist in the reset of the iron ball 7 after impact. A hydraulic cylinder 202 is installed at the bottom of the lifting box 2. The hydraulic cylinder 202 is a single-rod hydraulic telescopic cylinder. A fixed plate 201 is installed inside the lifting box 2 at the top of the hydraulic cylinder 202. Above the fixed plate 201 is a lifting plate 203 for moving the iron ball 7 upward. The outer wall of the lifting plate 203 slides in contact with the inner wall of the lifting box 2. The telescopic end of the hydraulic cylinder 202... The fixed plate 201 is fixedly connected to the lower surface of the lifting plate 203. The walls of the detection box 1 and the lifting box 2 are respectively provided with a first through hole 104 and a second through hole 105 at the hollow partition 101 and the horizontal plate 4. The two through holes serve as material passages for the iron ball 7 to enter the lifting box 2 from the detection box 1 and flow back to the detection box 1 from the lifting box 2. The top wall of the lifting box 2 is fixed with triangular guide plates 204 on both sides of the second through hole 105 to ensure that the iron ball 7 rolls smoothly through the second through hole 105 into the guide groove 401 of the horizontal plate 4. The upper surfaces of the perforated partition 101, the lifting plate 203, and the horizontal plate 4 are all designed as inclined surfaces. The inclination angle of the lifting plate 203 is smaller than that of the perforated partition 101. The motion assembly 6 includes a drive motor 601 and a protective box 602. The drive motor 601 is bolted to the top of the inner wall of the protective box 5. The protective box 602 is bolted to the top of the inner wall of the detection box 1. A magnetic coupler 6021 is installed inside the protective box 602. This coupler can automatically disengage under overload conditions. The output end of the drive motor 601 passes through the walls of the detection box 1 and the protective box 602 and is coaxially fixedly connected to the input end of the magnetic coupler 6021. The output end of the magnetic coupler 6021 is connected to a first lead screw 603. The end of the first lead screw 603 passes through the wall of the protective box 602 and is rotatably connected to the inner wall of the detection box 1. A parallel first guide rod 604 is provided on the side. A movable plate 605 is installed on the first lead screw 603 and the two first guide rods 604. The movable plate 605 is threadedly driven with the first lead screw 603 and slidably guided with the first guide rod 604. A baffle 6051 is fixed at the bottom of the movable plate 605. The baffle 6051 matches the end of the horizontal plate 4. Under normal conditions, the baffle 6051 blocks the port of the guide groove 401 and limits the iron ball 7. A pressure sensor is embedded in the outer wall of the protective box 602 facing the movable plate 605. When the movable plate 605 is close to the outer wall of the protective box 602, it squeezes the sensor. The pressure sensor collects the pressure signal and transmits it to the controller. After receiving the signal, the controller cuts off the forward power of the drive motor 601. The controller presets a program. After the impact is completed, the motor reverses and the hydraulic cylinder 202 lifts after a delay. In the case of ball jamming, the controller triggers the motor to rotate forward at low speed for a second time.

[0023] A rotating shaft 606 is rotatably installed at the bottom of the protective box 5. Both the rotating shaft 606 and the outer wall of the output end of the drive motor 601 are fixed with sprockets 607. The two sprockets 607 are connected by a transmission chain 6071. The drive motor 601 drives the rotating shaft 606 to rotate synchronously by means of the chain transmission. The detection box 1 is provided with a second lead screw 608 and a second guide rod 609 on both sides above the U-shaped fixed frame 3. One end of the second lead screw 608 passes through the detection box 1 and is fixedly connected to the rotating shaft 606. The other end of the second lead screw 608 is rotatably connected to the inner wall of the detection box 1. Both ends of the second guide rod 609 are fixedly connected to the inner wall of the detection box 1. A push plate 610 is installed on the second lead screw 608 and the second guide rod 609. The push plate 610 is threaded with the second lead screw 608 and slidably guided with the second guide rod 609. The lower surface of the push plate 610 is flush with the upper surface of the U-shaped fixed frame 3. The push plate 610 can push away the iron ball 7 that is stuck on the glass plate to be tested.

[0024] When conducting glass impact resistance testing, the operator first opens the two transparent sealing doors 102 of the testing box 1 and inserts the side of the flat glass to be tested into the U-shaped fixing frame 3 from the front to complete the omnidirectional clamping and fixing of the glass to be tested. After clamping, the two transparent sealing doors 102 are closed, and the testing chamber is sealed by the buffer pads inside the sealing doors. The iron ball 7 is placed in the guide groove 401 of the horizontal plate 4 in advance. At this time, the baffle 6051 is attached to the end of the horizontal plate 4 to block the port of the guide groove 401, and the iron ball 7 is limited and cannot roll down. Power is supplied by an external controller, which controls the drive motor 601 in the motion component 6 to start running in the forward direction. The output torque of the drive motor 601 is transmitted to the first lead screw 603 through the magnetic coupler 6021. The first lead screw 603 rotates in the forward direction. Under the guidance and limiting action of the first guide rods 604 on both sides, the moving plate 605 moves horizontally along the axis of the lead screw towards the protective box 602. At the same time, it drives the bottom baffle 6051 to gradually detach from the end of the guide groove 401 of the horizontal plate 4. The iron ball 7, which is no longer limited by the baffle 6051, rolls along the guide groove 401 based on the gravitational component of the inclined surface of the upper surface of the horizontal plate 4. It falls into the guide tube 404 through the arc groove 403 and falls vertically and freely along the hollow channel of the guide tube 404, accurately impacting the glass plate to be tested that is clamped and fixed on the U-shaped fixing frame 3. While the drive motor 601 is rotating forward, the sprocket 607 at the output shaft drives the rotating shaft 606 to rotate synchronously through the transmission chain 6071. The rotating shaft 606 drives the second lead screw 608 to rotate in the same direction. Under the guidance and constraint of the second guide rod 609, the push plate 610 moves to one side of the protective box 5. After the moving plate 605 continues to move to the right and presses the pressure sensor embedded in the outer wall of the protective box 602, the pressure sensor outputs a trigger signal, immediately cutting off the positive power supply of the drive motor 601, stopping the motor, and the single impact action of the iron ball 7 ends. Three scenarios may occur at this point: Scenario 1: The glass to be tested is intact and undamaged. After the iron ball 7 impacts the intact glass surface, it rebounds due to elasticity. In most cases, the iron ball 7 will rely on its rebound kinetic energy to roll along the upper surface of the glass and fall from the glass edge to the perforated partition 101. If the iron ball 7 remains on the upper surface of the glass and cannot roll down on its own due to factors such as the rebound angle or the coefficient of friction of the glass surface, the drive motor 601 is activated in reverse to drive the push plate 610 to move towards the iron ball 7, pushing the iron ball 7 to the edge of the glass so that it falls to the perforated partition 101, ensuring that the iron ball 7 smoothly enters the recycling path. After the iron ball 7 falls to the perforated partition 101, under the guiding and limiting action of the inclined surface of the perforated partition 101 and the triangular guide block 106, it rolls along the inclined surface into the first through hole 104 and falls into the lifting plate 203 inside the lifting box 2. At this time, the reverse start drive motor 601 is activated. The drive motor 601 reverses and drives the first lead screw 603 and the second lead screw 608 to rotate in the opposite direction. The moving plate 605 resets with the baffle 6051 and re-seals the guide groove 401 port. The push plate 610 synchronously returns to the initial standby position. The piston rod of the synchronous control hydraulic cylinder 202 extends upward, pushing the lifting plate 203 to rise vertically along the inner wall of the lifting box 2. When the lifting plate 203 reaches the same height as the second through hole 105, it stops lifting. The iron ball 7 rolls along the inclined surface of the lifting plate 203 through the second through hole 105 into the guide groove 401 on the horizontal plate 4. The baffle 6051 after being reset limits it again, completing the automatic reset of the iron ball 7. The device can directly carry out the next round of impact detection. Scenario 2: The glass is dented and broken, and the iron ball 7 is stuck in the dent without penetrating it. After the iron ball 7 is impacted, it gets stuck in the recess of the glass and cannot roll off. First, the drive motor 601 is reversed, and the drive baffle 6051 and push plate 610 are all returned to their initial positions. Then, the drive motor 601 is reversed at low speed. At this time, the moving plate 605 has been reset and is blocked by the limit. After the torque exceeds the rated value, the magnetic coupler 6021 slips and unloads, cutting off the power transmission from the drive motor 601 to the first lead screw 603. The main shaft of the drive motor 601 and the sprocket 607 continue to run. Relying on the chain drive, the second lead screw 608 is rotated, so that the push plate 610 can continue to move in the direction of the stuck ball, pushing the iron ball 7 stuck on the glass surface out of the groove. The iron ball 7 falls to the hollow partition 101. Subsequently, the iron ball 7 falls into the lifting plate 203 through the first through hole 104. It is lifted by the hydraulic cylinder 202 and transferred back to the guide groove 401 of the horizontal plate 4 through the through hole, which is exactly the same as the first situation, realizing the recovery of the iron ball 7. Scenario 3: The glass shatters completely, and the iron ball 7 penetrates the glass. After the iron ball 7 strikes and shatters the glass, it pierces through the glass and falls onto the perforated partition 101. Most of the small glass fragments produced by the breakage pass through the perforated mesh of the partition 101 under the influence of gravity and fall into the collection box 103 for collection. For a small number of larger fragments larger than the mesh, they remain on the upper surface of the perforated partition 101 along with the iron ball 7. However, as a spherical metal body, the iron ball 7 has a large mass and rolling inertia, and the large fragments are not enough to prevent the iron ball 7 from rolling along the inclined surface of the perforated partition 101. The iron ball 7 can easily roll over the fragments or push them away. Even under extreme conditions, where large glass fragments become embedded in the mesh of the perforated partition 101, the iron ball 7, due to its significant inertia after impact and the inclined surface of the partition 101, can, as it rolls past the embedded fragment location, utilize its own weight and the lateral displacement generated by the inclined surface force to bypass the embedding point and roll along another path on the partition surface into the first through hole 104. Therefore, the iron ball 7 recovery path possesses multiple fault tolerance capabilities, and the rare instances of fragment jamming do not affect the continuity and reliability of the overall iron ball 7 recovery. The iron ball 7 ultimately enters the lifting plate 203 inside the lifting box 2 along the inclined surface through the first through hole 104. The iron ball 7 is reset by lifting the lifting plate 203 through the hydraulic cylinder 202 and returning the flow to the guide groove 401 of the horizontal plate 4 through the second through hole 105. After the test, the tester can pull out the collection box 103 and clean the large pieces of debris (including fragments that may still be stuck in the mesh) remaining on the surface of the hollow partition 101. In cases two and three, if glass residue is attached to the surface of the iron ball 7, when the iron ball 7 falls to the perforated partition 101, the impact vibration and rolling contact between the iron ball 7 and the perforated partition 101 can cause the residue attached to the surface to fall off and fall into the collection box 103 through the mesh. This enables fully automatic cyclic reset of the iron ball 7. Regardless of whether the glass under test bounces back intact, is stuck due to breakage, or is shattered and passes through the ball after testing, the iron ball 7 can be automatically recovered and fed, forming an automatic closed-loop cycle of iron ball 7 placement, impact, and recovery. This eliminates the need for manual picking and resetting of each ball, reducing safety risks. Furthermore, the classified collection of glass residue allows for a direct and preliminary assessment of the glass's impact resistance, facilitating auxiliary evaluation of the glass's impact resistance.

[0025] Please see Figure 7As shown, the U-shaped fixing frame 3 is a U-shaped steel frame with its opening facing forward. The inner wall of the U-shaped fixing frame 3 has a snap-fit ​​groove 301, and an anti-slip rubber pad is adhered to the groove wall. After the side of the glass to be tested is snapped into the snap-fit ​​groove 301, lateral anti-slip limiting is achieved by the elastic deformation of the rubber pad. Multiple support plates 304 are fixed to the bottom of the U-shaped fixing frame 3. The side of each support plate 304 away from the wall of the testing box 1 is designed as a triangular face 3041. The triangular face 3041 can reduce the weight of the support and guide the falling iron ball 7. An abutment plate 302 is provided at the opening of the U-shaped fixing frame 3, and positioning plates 30 are fixed to both ends of the abutment plate 302. 22. Positioning grooves 303 are provided on both sides of the U-shaped fixing frame 3 corresponding to the positioning plates 3022. A soft pad 3021 is glued to the side of the abutment plate 302 facing the opening of the U-shaped fixing frame 3. Both positioning plates 3022 are detachably fixed in the positioning grooves 303 by screws. When assembling the glass to be tested, the two positioning plates 3022 slide vertically along the positioning grooves 303 until the soft pad 3021 tightly presses against the front end face of the glass to be tested. Then, fastening screws are used to pass through the positioning plates 3022 and lock them in the reserved threaded holes of the positioning grooves 303. The glass to be tested is clamped and fixed from the front, back, left and right directions to avoid the glass from slipping and shifting due to impact during the impact.

[0026] When installing the glass to be tested, insert the side of the glass to be tested into the snap-fit ​​groove 301 of the U-shaped fixing frame 3 from the front. The glass is initially limited laterally by the rubber pad in the groove. Then, hold the abutment plate 302 and slide the positioning plates 3022 at both ends vertically downwards along the positioning slide grooves 303 on both sides of the U-shaped fixing frame 3 until the soft pad 3021 on the inner side of the abutment plate 302 is tightly attached to the front end face of the glass to be tested. Then tighten the screws to lock the positioning plate 3022 into the positioning slide groove 303, thus completing the omnidirectional clamping and fixing of the glass to be tested.

[0027] The working principle of this invention is as follows: First, the operator opens the two transparent sealing doors 102 of the testing box 1, inserts the side of the glass to be tested into the snap-fit ​​groove 301 of the U-shaped fixing frame 3 from the front, and uses the rubber pad in the groove to complete the initial lateral positioning of the glass. Then, holding the abutment plate 302, the two end positioning plates 3022 are aligned with the positioning slide grooves 303 on both sides of the U-shaped fixing frame 3 and slide vertically downwards until the soft pad 3021 on the inner side of the abutment plate 302 is tightly attached to the front end of the glass to be tested. Then, the screws are tightened to lock the positioning plate 3022 inside the positioning slide groove 303, thus completing the omnidirectional clamping and fixing of the glass to be tested. After clamping, the two transparent sealing doors 102 are closed, and the testing chamber is sealed by the buffer pad on the inner side of the sealing door. The iron ball 7 is placed in the guide groove 401 of the horizontal plate 4 in advance. At this time, the baffle 6051 is attached to the end of the horizontal plate 4 to block the port of the guide groove 401, and the iron ball 7 is limited and cannot roll down. Power is supplied by an external controller, which controls the drive motor 601 in the motion component 6 to start running in the forward direction. The output torque of the drive motor 601 is transmitted to the first lead screw 603 through the magnetic coupler 6021. The first lead screw 603 rotates in the forward direction. Under the guidance and limiting action of the first guide rods 604 on both sides, the moving plate 605 moves horizontally along the axis of the lead screw towards the protective box 602. At the same time, it drives the bottom baffle 6051 to gradually detach from the end of the guide groove 401 of the horizontal plate 4. The iron ball 7, which is no longer limited by the baffle 6051, rolls along the guide groove 401 based on the gravitational component of the inclined surface of the upper surface of the horizontal plate 4. It falls into the guide tube 404 through the arc groove 403 and falls vertically and freely along the hollow channel of the guide tube 404, accurately impacting the glass plate to be tested that is clamped and fixed on the U-shaped fixing frame 3. While the drive motor 601 is rotating forward, the sprocket 607 at the output shaft drives the rotating shaft 606 to rotate synchronously through the transmission chain 6071. The rotating shaft 606 drives the second lead screw 608 to rotate in the same direction. Under the guidance and constraint of the second guide rod 609, the push plate 610 moves to one side of the protective box 5. After the moving plate 605 continues to move to the right and presses the pressure sensor embedded in the outer wall of the protective box 602, the pressure sensor outputs a trigger signal, immediately cutting off the positive power supply of the drive motor 601, stopping the motor, and the single impact action of the iron ball 7 ends. Three scenarios may occur at this point: Scenario 1: The glass to be tested is intact and undamaged. After the iron ball 7 impacts the intact glass surface, it rebounds due to elasticity. In most cases, the iron ball 7 will rely on its rebound kinetic energy to roll along the upper surface of the glass and fall from the glass edge to the perforated partition 101. If the iron ball 7 remains on the upper surface of the glass and cannot roll down on its own due to factors such as the rebound angle or the coefficient of friction of the glass surface, the drive motor 601 is activated in reverse to drive the push plate 610 to move towards the iron ball 7, pushing the iron ball 7 to the edge of the glass so that it falls to the perforated partition 101, ensuring that the iron ball 7 smoothly enters the recycling path. After the iron ball 7 falls to the perforated partition 101, under the guiding and limiting action of the inclined surface of the perforated partition 101 and the triangular guide block 106, it rolls along the inclined surface into the first through hole 104 and falls into the lifting plate 203 inside the lifting box 2. At this time, the reverse start drive motor 601 is activated. The drive motor 601 reverses and drives the first lead screw 603 and the second lead screw 608 to rotate in the opposite direction. The moving plate 605 resets with the baffle 6051 and re-seals the guide groove 401 port. The push plate 610 synchronously returns to the initial standby position. The piston rod of the synchronous control hydraulic cylinder 202 extends upward, pushing the lifting plate 203 to rise vertically along the inner wall of the lifting box 2. When the lifting plate 203 reaches the same height as the second through hole 105, it stops lifting. The iron ball 7 rolls along the inclined surface of the lifting plate 203 through the second through hole 105 into the guide groove 401 on the horizontal plate 4. The baffle 6051 after being reset limits it again, completing the automatic reset of the iron ball 7. The device can directly carry out the next round of impact detection. Scenario 2: The glass is dented and broken, and the iron ball 7 is stuck in the dent without penetrating it. After the iron ball 7 is impacted, it gets stuck in the recess of the glass and cannot roll off. First, the drive motor 601 is reversed, and the drive baffle 6051 and push plate 610 are all returned to their initial positions. Then, the drive motor 601 is reversed at low speed. At this time, the moving plate 605 has been reset and is blocked by the limit. After the torque exceeds the rated value, the magnetic coupler 6021 slips and unloads, cutting off the power transmission from the drive motor 601 to the first lead screw 603. The main shaft of the drive motor 601 and the sprocket 607 continue to run. Relying on the chain drive, the second lead screw 608 is rotated, so that the push plate 610 can continue to move in the direction of the stuck ball, pushing the iron ball 7 stuck on the glass surface out of the groove. The iron ball 7 falls to the hollow partition 101. Subsequently, the iron ball 7 falls into the lifting plate 203 through the first through hole 104. It is lifted by the hydraulic cylinder 202 and transferred back to the guide groove 401 of the horizontal plate 4 through the through hole, which is exactly the same as the first situation, realizing the recovery of the iron ball 7. Scenario 3: The glass shatters completely, and the iron ball 7 penetrates the glass. After the iron ball 7 strikes and shatters the glass, it pierces through the glass and falls onto the perforated partition 101. Most of the small glass fragments produced by the breakage pass through the perforated mesh of the partition 101 under the influence of gravity and fall into the collection box 103 for collection. For a small number of larger fragments larger than the mesh, they remain on the upper surface of the perforated partition 101 along with the iron ball 7. However, as a spherical metal body, the iron ball 7 has a large mass and rolling inertia, and the large fragments are not enough to prevent the iron ball 7 from rolling along the inclined surface of the perforated partition 101. The iron ball 7 can easily roll over the fragments or push them away. Even under extreme conditions, if large glass fragments are vertically embedded in the mesh of the perforated partition 101, the iron ball 7 has a large inertia after impact, and the surface of the perforated partition 101 is inclined. When the iron ball 7 rolls past the embedded fragment position, it can also rely on its own weight and the lateral displacement generated by the inclined surface force to bypass the embedded point and roll along other paths on the partition surface into the first through hole 104 and into the lifting plate 203 inside the lifting box 2. The iron ball 7 is reset by lifting the lifting plate 203 through the hydraulic cylinder 202 and returning the flow to the guide groove 401 of the horizontal plate 4 through the second through hole 105. After the test, the tester can pull out the collection box 103 and clean the large fragments remaining on the surface of the hollow partition 101.
