Embodiment Construction

[0016] see figure 1 and figure 2 , the drop testing machine 100 of the preferred embodiment of the present invention includes an electric control box 10 , a bearing assembly 30 , a ball dropping device 50 and a control device 70 . The electric control box 10 carries and is electrically connected to the bearing assembly 30 , the ball dropping device 50 and the control device 70 , and under the control of the control device 70 adjusts the vertical height of the ball dropping device 50 and the height of the bearing assembly 30 . The horizontal position of the object to be tested 200 enables the impact ball 300 with a certain weight to fall freely through the ball drop device 50 and hit each test point of the object to be tested 200 in turn, thereby applying a predetermined impact force to each test point to perform the test. Impact resistance test. In this embodiment, the object under test 200 is an electronic product, and the impact ball 300 is generally a shot ball.

Abstract

The invention discloses a drop test machine which is used for testing impact-resisting performance of an article to be tested. The drop test machine comprises a ball falling device, a load-bearing assembly and an electric cabinet electrically connected to the ball dropping device and the load-bearing assembly. The load-bearing assembly is used for bearing the article to be tested. The ball falling device is used for allowing an impact ball with the certain weight to fall on the article to be tested and offering preset impact force to test points of the article to be tested. The electric cabinet controls the ball falling device to adjust the falling vertical height of the impact ball and controls the load-bearing assembly to adjust the horizontal position of the article to be tested. Therefore, the impact ball falls down and is aligned with various test points of the article to be tested in sequence so that an impact-resisting performance test can be carried out on the various test points in sequence.

Description

technical field [0001] The invention relates to an electronic product testing device, in particular to a drop testing machine for testing the impact resistance of electronic products. Background technique [0002] Small consumer electronic products such as mobile phones, digital cameras, MP3 players, and personal digital assistants (PDAs) generally need to undergo drop tests to test the impact resistance of these electronic products. The method of the drop test is generally to place the item to be tested at a predetermined position, use an impact shot ball to freely fall from a preset height to impact the item to be tested, and detect the impact resistance of the item to be tested through the damage condition of the item to be tested. [0003] Existing drop test machines usually include a base, a bearing platform arranged on the base to carry the product to be tested, a slide bar on which the vertical bearing platform is arranged on the base, and a slide bar arranged on the ...
