Description

Technical Field

[0001] This utility model relates to the field of trackball technology, and specifically to an automatic trackball testing machine. Background Technology

[0002] A trackball is an input device used to control the movement of a cursor on a computer screen, typically used as a computer mouse, ultrasonic trackball, or touchpad replacement. The cursor movement is controlled by scrolling axes on the ball, and the user's gestures are captured by the rotation of the ball.

[0003] To ensure the performance of the trackball, it is necessary to test the trackball. Currently, the maximum thrust test of the trackball can only be performed on the trackball at a single angle, making it difficult to perform multi-directional testing of the trackball, thus limiting the testing capabilities. Utility Model Content

[0004] The purpose of this invention is to provide an automatic trackball testing machine to solve the aforementioned problems in current trackball testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic trackball testing machine includes a frame, a rotating mechanism, a trackball fixture, a thrust testing mechanism, and a trackball pressing mechanism. The rotating mechanism is located at the bottom of the frame, and the trackball fixture is located on the rotating mechanism. A trackball to be tested is placed in the trackball fixture. The thrust testing mechanism is located in the frame and on one side of the rotating mechanism. The thrust testing mechanism includes an X-axis linear module, a pressure sensor, and a test head. The X-axis linear module is located in the frame, and the test head is connected to the X-axis linear module through the pressure sensor. The X-axis linear module drives the test head to move to apply thrust to the trackball in the trackball fixture. The trackball pressing mechanism is located in the frame and above the trackball fixture. The trackball pressing mechanism is configured to press onto the top of the trackball when the test head applies thrust to the trackball in the trackball fixture.

[0007] Furthermore, the rotating mechanism includes a motor, a fixed base, and a rotating base. The motor and the fixed base are disposed at the bottom of the frame. The rotating base is rotatably connected to the fixed base. The motor is drively connected to the rotating base, and the rotating base can be driven to rotate by the motor. The top of the rotating base is located in the frame, and the trackball fixture is installed on the top of the rotating base.

[0008] Furthermore, the X-axis linear module is provided with a mounting plate, and a mounting base is provided on the side of the mounting plate. The pressure sensor is disposed in the mounting base, wherein one end of the pressure sensor is connected to the mounting plate and the other end is connected to the test head. The mounting base is provided with a sliding hole, and the test head is located in the sliding hole.

[0009] Furthermore, a push plate is provided at the end of the test head away from the pressure sensor, and the end of the push plate is arc-shaped.

[0010] Furthermore, the trackball pressing mechanism includes a Z-axis linear module and a roller. The roller is connected to the Z-axis linear module, and the Z-axis linear module can drive the roller to move up and down to press it onto the trackball on the trackball fixture.

[0011] Furthermore, a support frame is provided on the Z-axis linear module, and the roller is rotatably mounted on the support frame.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses an automatic trackball testing machine. A rotating mechanism drives the trackball fixture to rotate, which, combined with an X-axis linear module driving the test head, applies lateral thrust to the trackball. Simultaneously, a trackball pressing mechanism clamps the trackball during testing, allowing the trackball to be quickly switched to different testing angles and stably complete multi-directional thrust tests. Compared to current testing methods, this utility model achieves continuous detection of multi-directional thrust parameters of the trackball, significantly improving testing efficiency and data comprehensiveness. Furthermore, the synergistic effect of the thrust testing mechanism and the pressing mechanism prevents trackball deviation during testing, ensuring the accuracy of thrust application and the reliability of test results.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Combined with appendix Figure 1-5 This embodiment provides an automatic trackball testing machine, including a frame 1, a rotating mechanism 2, a trackball fixture 3, a thrust testing mechanism 4, and a trackball pressing mechanism 5.

[0023] like Figure 1 As shown, the frame 1 adopts a frame structure with a mounting platform 11 at the bottom. The rotating mechanism 2 is fixed on the mounting platform 11 and includes a motor 21, a fixed base 22, and a rotating base 23. The motor 21 is connected to the rotating base 23 via a belt 24. The rotating base 23 is rotatably mounted on the fixed base 22 via a bearing assembly, and its top extends into the working area of ​​the frame 1. The trackball fixture 3 is connected to the top of the rotating base 23 and is used to place the trackball 6 to be tested.

[0024] Figure 4 and Figure 5 As shown, the thrust testing mechanism 4 is arranged in the frame 1 and includes an X-axis linear module 41, a mounting plate 42, a mounting base 43, a pressure sensor 44, and a test head 45. The X-axis linear module 41 is mounted on the side wall of the frame 1, and the mounting plate 42 is vertically fixed to the moving end of the X-axis linear module 41. The mounting base 43 is fixed to the side of the mounting plate 42 and has a cavity inside. One end of the pressure sensor 44 is connected to the mounting base 43, and the other end is connected to the test head 45. A sliding hole 433 is opened at the front end of the mounting base 43, through which the test head 45 can slide, and an arc-shaped push plate 452 is fixed at the end. In this embodiment, the radius of curvature of the arc-shaped push plate 452 matches the radius of the trackball 6.

[0025] Figure 2 and Figure 3As shown, the trackball pressing mechanism 5 is installed on the top of the frame 1 and includes a Z-axis linear module 51, a support frame 52, and rollers 53. The Z-axis linear module 51 is vertically fixed to the top beam of the frame 1, and the support frame 52 is connected to the moving end of the Z-axis linear module 51. The rollers 53 are rotatably mounted on the support frame 52 via a pivot.

[0026] During testing, the trackball 6 is placed in the trackball fixture 3, and the Z-axis linear module 51 drives the roller 53 to press down and fix the trackball 6. After the motor 21 drives the rotating seat 23 to rotate to a predetermined angle, the X-axis linear module 41 pushes the test head 45 forward, so that the arc-shaped push plate 452 contacts the side of the trackball 6 and applies a pushing force. The pressure sensor 44 collects the pushing force data in real time. After the test is completed, the X-axis linear module 41 resets, and the rotating mechanism 2 can adjust the test angle to repeat the operation.

[0027] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
