Description

Technical Field

[0001] This utility model relates to the field of glass substrate testing, specifically a glass substrate testing device. Background Technology

[0002] The impact resistance of glass substrates is one of the core indicators for measuring their reliability, especially in fields such as displays and building curtain walls. If the impact resistance of glass substrates is insufficient, they may crack due to minor collisions during transportation, installation or use, leading to product scrapping or safety hazards. Therefore, impact resistance testing is a critical step before glass substrates leave the factory, but existing testing equipment has obvious limitations in terms of accuracy and practicality. The core issues with existing glass substrate impact resistance testing equipment lie in the stability and adaptability of the testing conditions: Existing equipment has flaws in its impact methods and weight settings. Some devices use robotic arms to push the weighted ball for impact instead of relying on natural gravity for descent. The pushing force is easily affected by factors such as mechanical wear and air pressure fluctuations, resulting in inconsistent initial velocities for each impact. This makes it impossible to simulate the force state of an object naturally falling and impacting glass in a real-world scenario, and the correlation between the test data and actual usage scenarios is weak. At the same time, most devices use a fixed weight for the weighted ball, while the impact resistance testing standards for glass substrates for different purposes (such as mobile phone display glass and architectural safety glass) vary greatly. Fixed-weight weighted balls cannot adapt to diverse testing needs, requiring equipment replacement or additional modifications, increasing testing costs and reducing efficiency.

[0003] In addition, the existing equipment has a cumbersome operating procedure, and the existing installation and fixing of the weight ball is inconvenient. It cannot quickly install the weight ball, and the impact position of the weight ball cannot be easily adjusted. It requires manual movement of the glass substrate or the weight ball release mechanism. These problems make it difficult for the existing equipment to balance detection accuracy and practicality, and it cannot meet the detection requirements of "efficient, accurate and adaptable to multiple scenarios" in glass substrate production.

[0004] Therefore, there is an urgent need for a device for testing the impact resistance of glass substrates. This device should ensure the stability of the glass by setting up a dedicated flat positioning platform, and use a weighted ball to fall naturally under gravity to ensure that the impact conditions are close to the actual scenario. At the same time, it should support the replacement of the weighted ball to adapt to different testing standards, thereby solving the problems of detection deviation and insufficient adaptability of existing equipment, and improving the accuracy and practicality of glass substrate impact resistance testing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please refer to Figure 1-3 As shown, this utility model provides a glass substrate testing device, including a base 1, a bracket 2 fixedly installed on the top of the base 1 and near one side, a sliding hole 3 for providing a sliding path is opened on the top of the bracket 2, a fixing strip 4 is slidably connected to the inner side of the sliding hole 3, an mounting block 5 is slidably connected to the inner side of the fixing strip 4, a driving component is installed on the top of the bracket 2, the driving component is used to drive the mounting block 5 to move laterally and longitudinally, a testing component for testing the impact resistance of the workpiece is installed on the inner side of the mounting block 5, and an anti-slip pad 24 is laid on the surface of the base 1, and a plurality of anti-slip grooves 25 are evenly arranged on the surface of the anti-slip pad 24.

[0019] In addition, the anti-slip pad 24 on the top of the base 1 fits against the workpiece to prevent it from sliding. The anti-slip groove 25 facilitates the removal and unloading of the workpiece and the brushing of residues on the surface of the anti-slip pad 24. The two ends of the fixing strip 4 are embedded in the sliding hole 3. The driving component drives the fixing strip 4 to move laterally within the sliding hole 3. Then, the driving component drives the mounting block 5 to move longitudinally, so that the mounting block 5 can move the detection component to multiple points. This allows the detection component to impact the workpiece with free gravity at multiple different points, improving the accuracy and practicality of the detection component in detecting the quality of the workpiece.

[0020] Specifically, the driving component includes a first cylinder 6 fixedly installed on one side of the bracket 2. A first push rod 7 for driving the fixing bar 4 to move laterally is fixedly installed at one end of the first cylinder 6. An electric telescopic rod 8 is installed at the other end of the fixing bar 4. The electric telescopic rod 8 is fixedly connected to the mounting block 5. Limiting portions 23 extend from both sides of the mounting block 5, and the limiting portions 23 are slidably connected to the fixing bar 4.

[0021] The first cylinder 6 can move laterally within the sliding hole 3 by pushing the fixed strip 4 through the first push rod 7. The limiting parts 23 on both sides of the mounting block 5 are embedded inside the fixed strip 4 to prevent the mounting block 5 from shifting and to increase the stability of the sliding between the mounting block 5 and the fixed strip 4. The electric telescopic rod 8 can drive the mounting block 5 to move longitudinally within the fixed strip 4, thereby enabling the detection element at the bottom of the mounting block 5 to form a rectangular range of motion, improving the convenience and accuracy of the detection element in multi-directional impact testing of the workpiece.

[0022] More specifically, the testing component includes a fixing groove 9 at the bottom of the mounting block 5, a mounting bracket 10 placed inside the fixing groove 9, the mounting bracket 10 being screwed to the weight ball 12 via a connecting rod 11, a connecting rope 13 connecting the mounting bracket 10 to the bottom of the mounting block 5, a second cylinder 14 mounted on the top of the mounting block 5, a second push rod 15 mounted at the bottom of the second cylinder 14, a push ball 16 screwed to the end of the second push rod 15, a circumferentially arranged fixing cavity 17 on the inner side of the mounting block 5, a connecting plate 18 slidably connected to the inner side of the fixing cavity 17, a driven rod 19 fixedly connected to one side of the connecting plate 18, a locking rod 20 fixedly connected to the other side of the connecting plate 18, a spring 21 fitted on the outer side of the locking rod 20, and multiple circumferentially arranged locking grooves 22 on the inner edge of the mounting bracket 10. It should be added that the weighted ball 12 is a known weighted ball 12, and different weighted balls 12 can be replaced through the connecting rod 11 to conduct multiple different drop impact force tests. The mounting bracket 10 is screwed to the weighted ball 12 through the connecting rod 11. The mounting bracket 10 can be embedded in the fixing groove 9. The second cylinder 14 drives the second push rod 15 to drive the ball 16 to move upward. The spring 21 in the fixing cavity 17 squeezes and pushes the connecting plate 18, causing the locking rod 20 on one side of the connecting plate 18 to disengage from the locking groove 22. The weighted ball 12 drives the mounting bracket 10 to move downward to strike the workpiece, improving the accuracy and practicality of the weighted ball 12 in testing the impact strength of the workpiece.

[0023] Working principle: First, the first cylinder 6 and the electric telescopic rod 8 are activated as needed. The first cylinder 6 moves the fixed strip 4 laterally in the sliding hole 3 through the first push rod 7. At the same time, the electric telescopic rod 8 drives the mounting block 5 to move longitudinally in the fixed strip 4. Then, the second cylinder 14 drives the second push rod 15 to drive the push ball 16 to move upward. The pushing force of the push ball 16 on the driven rod 19 disappears. The spring 21 in the fixed cavity 17 squeezes and pushes the connecting plate 18, causing the locking rod 20 on one side of the connecting plate 18 to disengage from the locking groove 22. The heavy ball 12 drives the mounting frame 10 to move downward to strike the workpiece. At the same time, the connecting rope 13 connects the mounting frame 10 and the heavy ball 12.
