Description
Technical Field
[0001] The utility model relates to the technical field of optical disc box quality detection, in particular to a BD optical disc box strength detection device. Background Art
[0002] A BD disc case is a container used to store Blu-ray Discs (BDs). Blu-ray Discs are a high-density optical disc format designed for storing high-quality audiovisual content and large amounts of data. BD disc cases are typically used to protect and organize these discs, preventing them from scratching or contamination while also making it easier for users to store and find them. These cases are typically made of plastic and designed to accommodate single- or double-sided Blu-ray Discs. Some cases also feature a transparent window so users can clearly see the disc inside.
[0003] The strength test of the optical disc case is an important step to ensure that the optical disc can effectively protect the contents of the optical disc from damage during long-term storage and use. The test content includes the pressure resistance and impact resistance of the case body, so as to ensure that the optical disc case can stably protect the optical disc in different environments and prevent damage to the optical disc or loss of contents due to external factors such as squeezing and vibration. At present, there is no special strength testing device for optical disc cases on the market. When the optical disc case is subjected to pressure or impact resistance testing, it can only be taken to a special pressure strength tester or impact resistance testing machine for testing. Such a testing process is too cumbersome and time-consuming, and it is impossible to perform continuous or simultaneous testing, and the testing efficiency is low. Utility Model Content

The handle 21 drives the bidirectional screw rod 20 to rotate. The bidirectional screw rod 20 drives the two clamping plates 9 to approach each other to clamp the BD disc case. Then the electric telescopic rod 4 extends to drive the pressure plate 7 to move downward and press on the BD disc case. The pressure sensor 6 will transmit the real-time pressure to the compressive strength tester 10. The pressure is increased until the pressure when the BD disc case is crushed, which is the compressive strength of the BD disc case. When performing an impact strength test on the BD disc case, first place the BD disc case into the protective box 11, then adjust the height of the electromagnetic chuck 16 through the locking knob 14. The electromagnetic chuck 16 is powered off to allow the steel ball 17 to freely fall from different heights and hit the BD disc case until the BD disc case is damaged. At this time, according to the calculation formula of the free-fall impact force Ft = mv, the impact strength of the BD disc case is calculated.
