Description

Technical Field

[0002] The glass drop ball test is a process in which a metal ball of a specific weight falls freely from a specific height (or several specific heights) onto a specific point on the glass, and the strength of the glass is tested by observing whether the glass breaks. The existing glass drop ball test method is to position the fixture with the test device through a positioning column; and then position the glass through a positioning groove or positioning column on the fixture. In this way, the relative position of the glass and the test device is fixed, and a single-point drop ball test can be performed.

[0003] Since the positioning methods of glass and fixture, fixture and measuring device are all limited by positioning columns and positioning slots, the spatial coordinates of the glass are fixed and cannot be moved, and a single fixture can only test one point of the glass. If multi-point measurement is required, it is necessary to design and process a lot of fixtures, and the measurement cost and cycle are relatively high. In addition, since the falling height of the metal ball is fixed, the equal-height drop ball test can only be applied to flat glass and cannot be used to test curved glass.

[0004] Based on this, a new solution is needed. Utility Model Content

Figure 7As shown, the XY moving platform 3 includes a base plate 31 , a first sliding plate 32 , a first scale block 33 , a first sliding assembly 34 , a second sliding plate 35 , a second scale block 36 , a second sliding assembly 37 , a positioning column 38 and a positioning pin 39 .

[0035] Combine the following Figure 9-11 The following describes the use of the adjustable drop ball test device provided by the utility model:

[0036] 1. Adjust the test point: Position the fixture on the XY moving platform; move the first sliding plate and the second sliding plate until the arrow points to the XY coordinate value to be measured, and tighten the handle screws;

[0037] 2. Adjust the height of the ball: Position the glass on the fixture; use the spherical probe to find the initial position of the ball (e.g. the measuring point is 10 cm higher than the glass); fix the slider at a specific position according to the initial coordinates; press the suction switch of the vacuum suction cup, and the suction cup will suck the ball;

[0038] 3. Test, observe and record: Press the suction switch, turn off the suction, and the ball falls and hits the glass. Observe whether the glass is broken and record it.

[0039] The adjustable falling ball test device provided by the utility model has the following characteristics:

[0040] 1. Strong adaptability to products: This device can be used not only for multi-point drop ball testing of flat glass, but also for 3D curved glass, solving the problem of inaccurate drop ball height caused by height changes at each measuring point of curved glass;

[0041] 2. Strong adaptability to metal balls: This device does not require a round tube guide, and the suction cup can absorb balls of various sizes. As long as the weight of the ball is less than the suction force of the suction cup, the ball drop experiment can be carried out;

[0042] 3. High adjustment accuracy: The scale unit of this device is mm, and the glass point and the drop height of the ball can be accurate to 1mm, which is far less than the tolerance requirement of the drop ball test;

[0043] 4. There are fewer factors affecting the falling of the ball: Since the ball falls freely, the tube guidance is cancelled, and factors such as the collision and friction of the tube that reduce the impact force of the falling ball no longer exist.
