Description

Technical Field

[0001] This utility model relates to the technical field of glass testing, and in particular to a ball dropper for testing tempered glass. Background Technology

[0002] Tempered glass is a type of safety glass. To improve its strength, physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving its load-bearing capacity and enhancing its impact resistance. Therefore, tempered glass needs to undergo multiple tests before production to determine its impact resistance.

[0003] Currently, most tests on the impact resistance of tempered glass utilize a method of constructing an iron tower or ladder in an open area. The operator, holding a 1kg iron ball, climbs to the required height, aligns the ball with the center of the tempered glass at the bottom, and releases it after the personnel below have evacuated. The ball then falls freely onto the tempered glass. If the tempered glass does not shatter, the operator raises the height again and releases the ball once more, repeating this process until the tempered glass shatters. Throughout this process, the drop height of the ball needs to be continuously recorded to refine the experimental data.

[0004] However, in existing experiments, the falling iron ball is easily affected by factors such as whether external force is applied when it is released, external temperature and humidity, and wind speed, leading to inaccurate experimental results and data. Furthermore, after the iron ball falls and impacts the tempered glass, it may bounce wildly and injure the operator, or shatter into glass fragments that may fly around and injure the operator, compromising operator safety during the experiment.

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-6 As shown, a ball-dropping machine for testing tempered glass includes a frame body 1, a ball-dropping mechanism 2, and a collection mechanism 3. A protective cover 4 is installed around the frame body 1, forming a sealed space. A lifting track 5 is installed on the inner wall of the frame body 1, and the lifting track 5 is laid along the longitudinal direction of the frame body 1. The ball-dropping mechanism 2 includes a motion seat 21 slidably mounted on the lifting track 5 and a test iron ball 22 selectively mounted on the motion seat 21. The ball-dropping mechanism 2 can move along the longitudinal direction of the lifting track 5 to a certain height and then control the test iron ball 22 to separate from the motion seat 21, allowing the test iron ball 22 to undergo free fall. The collection mechanism 3 is located at the bottom of the sealed space, and the top of the collection mechanism 3 has an opening, through which the tempered glass to be tested can be placed.

[0034] In this embodiment, a ball-dropping machine for tempered glass testing forms a sealed space by setting up a frame body 1 and a protective cover 4 around the frame body 1. A lifting track 5, a ball-dropping mechanism 2, and a collection mechanism 3 are placed within this space. This allows for control of the ball's height and automatic ball drop, while also improving the collection of broken glass. This significantly improves testing accuracy, efficiency, safety, and convenience. The ball drop position is controlled by a servo motor, enabling automatic, rapid, and precise movement to the set height. An electromagnetic ball-dropping mechanism automatically drops the iron ball. This process takes place within the enclosed frame, isolating the machine from external temperature, humidity, and wind conditions. This shields against external influences and prevents the iron ball from flying erratically, ensuring the safety of the personnel during the experiment. The bottom collection box collects all broken glass and iron balls for unified disposal after the experiment.

[0035] Furthermore, the main frame 1 includes a frame base 11, a collection box frame 12, and multiple frame units 13 connected sequentially from top to bottom. Adjacent frame units 13 are detachably connected, with the bottommost frame unit 13 detachably connected to the collection box frame 12, and the collection box frame 12 detachably connected to the frame base 11. The main frame 1 is primarily made of aluminum alloy and is mainly used to install the PC protective plate (protective cover 4), lifting rail 5, bottom collection box 31, and top drive motor (servo motor 6). The aluminum alloy frame is lightweight and aesthetically pleasing, allowing for easy relocation of the installation position, and facilitating on-site maintenance and installation. Therefore, this equipment can be installed in the reserved shaft inside the experimental building, and the overall frame height can be increased later according to experimental needs. The outer side of the frame is fully wrapped with PC board to prevent the test iron ball 22 from flying around and to isolate it from external factors, providing a closed space free from wind and external forces.

[0036] Furthermore, the protective cover 4 comprises multiple covers, and the multiple protective covers 4 are respectively fastened to the frame unit 13 and the collection box frame 12. This facilitates installation and disassembly.

[0037] Furthermore, the motion seat 21 includes a linear slider 211 that slides along the lifting track 5 and a mounting plate 212 bolted to the linear slider 211. The mounting plate 212 is perpendicular to the lifting track 5. An electromagnet 23 is mounted on the end of the mounting plate 212 away from the linear slider 211. The electromagnet 23 is energized and demagnetized, and can attract the test iron ball 22. Furthermore, the contact area between the electromagnet 23 and the test iron ball 22 is hemispherical. The electromagnetic ball-falling mechanism is mainly used to attract the test iron ball 22 and simultaneously send the test iron ball 22 to the corresponding experimental height. After the power is turned off, the electromagnet 23 is demagnetized, and the test iron ball 22 falls freely to conduct the experiment. For safety reasons, in the event of a sudden equipment failure or a power outage in the workshop, the test iron ball 22 must be firmly attracted by the electromagnet 23 of the ball dropping mechanism 2 and must not fall off in a non-experimental state. Therefore, the electromagnet 23 is made to be magnetic when the power is off and non-magnetic when the power is on. The contact area between the electromagnet 23 and the test iron ball 22 is made into a hemispherical surface to increase the contact area between the magnet and the iron ball. It has been verified that the iron ball cannot be removed when the power is off, and falls freely when the power is on.

[0038] Furthermore, the collection mechanism 3 includes a collection box 31 and a conical hopper 32. The collection box 31 is placed on the frame base 11, and the conical hopper 32 is located directly above the collection box 31. The top of the conical hopper 32 is detachably connected to the collection box frame 12, and the tempered glass is placed on the conical hopper 32. The broken glass collection box 31 is mainly used to collect the tempered glass that is broken during the experiment. Above it is a funnel-shaped broken glass collection trough, with the tempered glass suspended in the center. When the test iron ball 22 falls and breaks the tempered glass, it falls into the collection box 31. When the box is full of broken glass, it can be pulled out for disposal.

[0039] Furthermore, the ball-dropping mechanism 2 can slide along the lifting track 5 under the action of the servo motor 6 driving the synchronous belt 7. In this embodiment, the synchronous belt lifting mechanism is mainly controlled by the servo motor through the PLC. The servo motor 6 sends the electromagnetic ball-dropping mechanism 2 to the corresponding experimental height through the synchronous belt 7. The servo motor 6 can accurately control the height position of the ball-dropping mechanism 2 and record it on the operation screen. The synchronous pulley and the synchronous belt can ensure accurate height position without loss.

[0040] Furthermore, the protective cover 4 located on the collection box frame 12 serves as an openable protective door. When the box is full of broken glass, the protective door can be opened to pull out the collection box 31 for disposal. The operation is convenient and quick.

[0041] Detailed process of the ball-dropping experiment:

[0042] First, open the protective door and place the tempered glass on the conical bucket 32 ​​in the center of the equipment. The tempered glass should be in contact with the support points around its perimeter, with the center suspended in the air. Place a 1kg test iron ball 22 under the electromagnet 23. The test iron ball 22 will be attracted by the magnet. Close the protective door and input the specified height on the operation screen. The magnet mechanism will automatically move to the specified height. Once ready, press the ball-drop button. The electromagnet 23 will be energized and demagnetized, and the test iron ball 22 will fall freely onto the tempered glass below. Open the door to check if the tempered glass is cracked or broken. Record the results, then place the test iron ball 22 under the electromagnet 23 again. Close the door and input different heights to repeat the above operation. Accumulate the experiments and record the data step by step. The screen will display and record all experimental heights and data.
