Automatic Steel Ball Impact Tester for Electronic Products Machine Features
- Computer-Controlled Precision: The machine is controlled by computer software, allowing users to set and control parameters such as rise, fall, drop times, drop height, and infrared laser aiming at the impact part of the steel ball. Test methods, including impact height, steel ball weight, impact times per point, and coordinates for the XY platform, can be saved and called by user-defined file names.
- Detailed Display and Reporting: The software displays the number of tests performed, current height values, and the impact energy value of the steel ball. After testing, the XY platform automatically returns to the origin, with sound and light alarms signaling completion. The system calculates and displays the impact energy in MJ based on the set height and ball weight. A test report is automatically generated after each test.
- Accurate Z-Axis Control: The Z-axis uses a Japanese Panasonic AC servo motor with a reducer for lifting. The program controls the height, maintaining a positioning error of ≤1mm.
- Efficient Suction Mechanism: The machine uses a Japanese SMC vacuum suction cup to hold the steel ball. The ball is automatically lifted and released for a free-fall test, impacting the surface of the specimen.
- Infrared Laser Positioning: An infrared laser locates the precise impact point, ensuring accurate targeting before each test.
- Secondary Impact Prevention: The machine's program prevents secondary impacts. During the test, a Japan SUNS laser sensor detects the falling steel ball, and an SMC lead cylinder synchronously loads the ball to prevent it from bouncing back.
- High Precision XY Platform: Driven by a Panasonic servo motor, the XY platform features THK ball screws and guide rails, ensuring positioning accuracy of ≤±0.02mm and repeatability of ≤±0.01mm. The platform operates smoothly with low jitter, ensuring stable testing conditions.
- Automatic Compensation and Calculation: The system compensates the impact height based on the steel ball's diameter and calculates the impact energy according to the ball's weight. After testing, the impact strength is displayed.
Impact Strength Calculation
The impact strength value (J) is calculated using the following formula:
\[ J = 9.8 \times 0.001 \times H \times W \]
- \( J \): Impact value, N.m
- \( H \): Falling height of sphere, mm
- \( W \): Falling ball mass, kg
Qualitest's Automatic Steel Ball Impact Tester ensures precise and reliable testing of electronic products, helping manufacturers evaluate and improve the durability and impact resistance of their devices.
Control Software:
1. Language Interface: The control software features a switchable language interface, making it suitable for a diverse range of customers.
2. Authority Levels: The software includes three levels of authority classification: default, engineer, and debugging. Logging in is required to access engineer and debugging authority levels.
3. Test Interface Functions:
- Alarm Prompts: The interface includes alarm prompts, fault alarms, and motor fault alarms.
- XYZ Axis Display: Current values for the XYZ axes are displayed.
- Test Coordinate Preview: The interface displays a cross mark on current test coordinate points, with tested or being-tested points shown in red.
- Test Results: Results are displayed by the number of times tested. The XY coordinate values, height values, and impact energy for each impact can be saved and recalled.
- Report Naming: The default report name includes the test method name and test time.
- Function Keys: Include test, stop, reset, stop position, laser switch, door lock safety function switch, and alarm release switch.
4. Test Method Functions:
- Path Assignment: Test method path assignment, save, and call-out functions are available.
- Naming: Test methods can be named.
- Settings: Steel ball diameter, quality, and product thickness settings.
- Coordinate Editing: Includes coordinate matrix, manual input, and external handle point-taking functions.
- Impact Settings: The impact height and impact energy can be set independently for each row of coordinates. The software can automatically calculate the impact energy based on the input height, or calculate the impact height based on the input energy. Each row can independently set the number of shocks.
- Error Prompts: A red prompt appears when input data is out of range.
- XYZ Stop Position: Settings are available for the XYZ stop position.
5. Report Output: The report output format is Excel.
