The lifting slider 314 is connected to the first connecting plate, and the first connecting plate drives the lifting slider 314 to move together.

[0030] like Figure 1 As shown, in some embodiments, the ball releasing part 32 also includes a first connecting rod 321 and a second connecting rod 322, the first connecting rod 321 is connected to the lifting slider 314, the lifting slider 314 drives the first connecting rod 321 to move together, the second connecting rod 322 is connected to the first connecting rod 321, the second connecting rod 322 moves with the movement of the first connecting rod 321, and the first connecting rod 321 and the second connecting rod 322 are vertically arranged, the electromagnet is arranged on the second connecting rod 322, the electromagnet moves with the movement of the second connecting rod 322, and the height of the iron ball 33 is controlled by controlling the height of the electromagnet.

[0032] like Figure 1 As shown, in some embodiments, the moving structure 21 also includes a second connecting plate, a moving guide rail 212 and a moving slider 213. The second connecting plate is connected to the moving cylinder, and the second connecting plate can move with the movement of the moving cylinder. The second connecting plate is connected to the moving slider 213, and the second connecting plate drives the moving slider 213 to move synchronously. The moving slider 213 is movably arranged on the moving guide rail 212.

[0033] like Figure 1 As shown, in some embodiments, the test assembly 20 also includes a test platform 22, and the test platform 22 is connected to the moving slider 213, and the test platform 22 moves with the movement of the moving slider 213. The device has a test state in which the test platform 22 corresponds to the electromagnet, or a non-test state in which the test platform 22 does not correspond to the electromagnet. The product to be tested is placed on the test platform 22. As the test platform 22 moves, the product to be tested is located below the iron ball 33, that is, it is in a test state. At this time, the electromagnet is disconnected from the power supply and loses its magnetism, the iron ball 33 falls, and the iron ball 33 collides with the product to be tested. After the drop ball impact test is completed, the moving motor 211 drives the moving lead screw to reverse, so that the test platform 22 moves backward. At this time, the test platform 22 does not correspond to the electromagnet, that is, it is in a non-test state.

[0034] like Figure 1 and Figure 3As shown, in some embodiments, the base assembly 10 has a ball-dropping groove 11, and the ball-dropping groove 11 is arranged corresponding to the electromagnet. The ball-dropping groove 11 includes a ball-dropping plate, a first side wall, a second side wall, and a third side wall. The first end of the ball-dropping plate is connected to the first end of the first side wall, the second end of the first side wall is connected to the first end of the second side wall, the second end of the second side wall is connected to the first end of the third side wall, and the second end of the third side wall is connected to the second end of the ball-dropping plate. The ball-dropping plate, the first side wall, the second side wall, and the third side wall are all arranged at an inclined angle, so that the ball-dropping groove 11 forms a structure with an upper opening and a lower closing, and the opening is rectangular. In the test state, from the position of the electromagnet, the ball drop plate is not blocked by the test platform 22. This setting allows the iron ball 33 to accurately fall into the ball drop groove 11 without being easily affected by the test platform 22. At the same time, the iron ball 33 rolls along the ball drop plate to a position directly opposite the electromagnet and stops (the iron ball 33 stops when it abuts against the ball drop plate, the first side wall, the second side wall, and the third side wall). After the test is completed, the test platform 22 moves backward, and the iron ball 33 is completely exposed. At this time, the electromagnet moves down and turns on the power to adsorb the iron ball 33, so that the iron ball 33 is recovered and it is convenient for retesting.

[0035] like Figure 1 As shown, in some embodiments, the test platform 22 has an inclination angle in the direction close to the ball-dropping groove 11. The inclination angle is 5° to 10°, and the inclination angle in this embodiment is 5°. This setting makes it easier for the iron ball 33 to fall into the ball-dropping groove 11 along the inclination direction of the test platform 22 after the collision.

[0036] like Figure 1 As shown, in some embodiments, the test platform 22 is provided with an opening in a direction close to the ball-dropping groove 11 to facilitate the iron ball 33 to fall into the ball-dropping groove 11 .

[0037] It should be noted that the device also includes a control component, which is a PLC controller. The control component is electrically connected to the lifting motor 312, the moving motor 211 and the power supply of the electromagnet.

[0038] The control process is as follows: the control component controls the lifting motor 312 to work, so as to adjust the lifting height of the electromagnet, and then adjust the height of the iron ball 33 to the test height; the control component controls the moving motor 211 to work, so as to realize the movement of the test platform 22, at which time the test platform 22 corresponds to the iron ball 33; the control component controls the power supply of the electromagnet to be disconnected, the electromagnet loses its magnetism, and the iron ball 33 falls to carry out a falling ball impact test; after the test is completed, the iron ball 33 rolls into the falling ball groove 11, and the control component controls the lifting motor 312 to work, driving the electromagnet to move downward; the control component controls the power supply of the electromagnet to be turned on, and the electromagnet realizes the adsorption of the iron ball 33 through magnetism.

[0039] It should be noted that the control component has a preset initial height of the iron ball 33. Under the test state, the lifting structure 31 drives the iron ball 33 to move downward. The height value obtained by subtracting the downward height from the initial height is recorded as H. The impact energy of the iron ball 33 is: E=mgH.

[0040] E: impact energy;

[0041] H: the difference between the initial height of the iron ball 33 and the height of the iron ball 33 when it moves downward;

[0042] m: mass of iron ball 33;

[0043] g: acceleration due to gravity.
