Description

Technical Field

[0001] This utility model relates to the field of screen testing technology, and in particular to a ball drop cycle device. Background Technology

[0002] Before a display screen leaves the factory, it needs to undergo a series of tests, one of which is the ball drop test, used to test the screen's impact resistance. The traditional testing method involves dropping small balls stored in a chamber onto the screen one by one. This method requires manually collecting the balls, making the test inconvenient.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ball drop cycle device to automatically perform ball drop tests on the screen, reduce labor intensity, and improve the level of automation.

[0005] The technical solution of this utility model is as follows: A ball drop circulation device is provided, including: a screen placement box, a ball sliding chute, a ball lifting device, and a ball drop chute; the screen placement box is provided with a ball outlet, the lower part of the ball lifting device is provided with a ball inlet, the upper part of the ball lifting device is provided with a ball outlet, the horizontal height of the ball inlet is lower than the horizontal height of the ball outlet, the two ends of the ball sliding chute are respectively connected to the ball outlet and the ball inlet, and one end of the ball drop chute is connected to the ball outlet, and the other end is located directly above the screen placement box.

[0006] The screen is placed inside a screen placement box, and a small ball is placed on the screen. The ball then rolls towards the ball outlet, flows through a ball chute to the ball inlet, and is then lifted by a ball lifting device to the ball outlet. The ball then flows into a ball drop chute and falls down. Since the screen placement box is directly below the falling ball, it lands on the screen, thus achieving automatic screen testing and greatly simplifying the application. Furthermore, this solution has a simple and convenient structure, eliminating the need for a dedicated storage room for the balls. It can also be used as a demonstration for screen testing, showcasing the testing process to the public in a clear and intuitive way.

The ball enters the ball lifting channel through the ball inlet, and the drive device drives the ball lifting screw to rotate, thereby lifting the ball to the ball outlet.

[0008] Furthermore, the cylindrical frame includes: a base plate with a pivot hole, a top plate, several support rods connecting the base plate and the top plate, and a movable ring threaded on the support rods; all the support rods form a cylindrical or near-cylindrical shape, the ball outlet is located on the movable ring, and the ball inlet is located on the base plate. The cylindrical or near-cylindrical shape created by the support rods allows for gaps, enabling observation of the ball's lifting process and providing a clear visual demonstration. The movable ring is used to move the ball drop chute up and down, thereby adjusting the ball's drop height to meet the needs of drop tests at different heights.

[0009] Furthermore, the support rod passes through the base plate and connects to the base.

[0010] Furthermore, the drive device is connected to the central shaft of the ball lifting screw via a power transmission device.

[0011] Furthermore, the power transmission device comprises a worm gear connected to the central rotating shaft and a worm connected to the output shaft of the drive device, wherein the worm gear and the worm cooperate; the drive device is a motor. Using a worm gear power transmission device facilitates the layout of the motor.

[0012] Furthermore, the screen placement box includes: a back plate, four side plates connected to the back plate, support plates mounted on the side plates, and a panel connected to the support plates; the panel is provided with a screen placement slot, and the four side plates and the panel form a ball receiving slot, with a ball outlet communicating with the ball receiving slot. By replacing the panel with screen placement slots of different sizes, different screens can be tested.

[0013] Furthermore, the ball drop circulation device further includes: a main board and control buttons, wherein the main board is electrically connected to the drive device and the control buttons. Preferably, the main board is installed inside the screen placement box, and the control buttons are installed on the surface of the screen placement box.

[0014] Furthermore, the ball drop chute has an opening at the bottom at one end directly above the screen placement box. This bottom opening eliminates horizontal velocity, allowing the ball to fall vertically.

[0015] Furthermore, the ball drop circulation device also includes a mounting plate, on which the screen placement box and the ball lifting device are mounted.

[0016] Using the above solution, this utility model provides a ball drop cycle device. The screen placement box and ball lifting device achieve ball circulation through a ball sliding chute and a ball drop chute. By controlling the drop distance, drop position, and impact force of the ball in the drop experiment, automatic cyclic testing of the ball drop experiment is achieved. Simultaneously, the drop position, drop distance, and impact force of the ball can be controlled, providing a visual demonstration of screen performance and enabling automatic cyclic display of the ball drop experiment, reducing manual operation and saving labor costs.
