Description

Technical Field

[0001] This utility model relates to the field of positioning technology for button testing, specifically a positioning clamping fixture for button testing. Background Technology

[0002] Button testing is a comprehensive evaluation process for the performance of electronic device buttons, aiming to ensure that the quality and feel of the buttons meet design requirements and improve user experience. Button testing mainly includes the following aspects: Actuation Force Test: This measures the force required to press the button, usually expressed in Newtons (N) or grams per force (gf). Different devices have different actuation force requirements; testing machines can accurately measure this parameter to ensure button comfort and consistency. Travel Test: This measures the distance from the button's initial position to its fully depressed position. A suitable travel distance provides clear feedback, avoiding issues such as unresponsive or slow button response. Rebound Speed ​​Test: This measures the rebound speed of the button after it is pressed; a faster rebound speed improves operational sensitivity. Durability Test: This simulates the wear and tear of buttons after prolonged use, testing the button's durability and stability through repeated pressing. Feedback Force Test: This tests the feedback force of the button when it is pressed; good feedback force provides a clear tactile feel, improving user experience.

[0003] Currently, existing button testing technologies require the use of positioning and clamping fixtures to ensure the accuracy and efficiency of the testing process. However, existing fixtures have limitations in positioning accuracy and clamping force, leading to instability in test results and affecting the overall testing effectiveness.

[0004] Therefore, this utility model provides a positioning clamping fixture for button testing. Utility Model Content

[0005] The purpose of this invention is to provide a positioning and clamping fixture for button testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and clamping fixture for button testing, comprising a button testing platform, a positioning and clamping device provided on the button testing platform, the positioning and clamping device including at least one positioning and clamping mechanism, a button product provided on the button testing platform, a lifting probe provided at the bottom of the button product, and the precise positioning of the button product achieved by the lifting probe cooperating with the button testing platform; the button testing platform is also provided with a pad fixing seat, an L-shaped plate fixedly connected to the top of the fixing seat, two connecting blocks installed on the top of the L-shaped plate, and positioning guide blocks installed on the two connecting blocks.

[0007] Preferably, the positioning and clamping mechanism includes a cylinder connecting seat, which is installed on the button test bench. An external push cylinder is connected to the outside of the cylinder connecting seat. The piston rod of the push cylinder is connected to a moving rod. Positioning seats A and B are provided on both sides of the moving rod. A triangular block is fixedly connected to the other end of the moving rod.

[0008] Preferably, a guide post is fixedly connected between the positioning seat A and the positioning seat B. A spring is sleeved on the outer wall of the guide post. One end of the spring is fixedly connected to the positioning seat A, and the other end of the spring is fixedly connected to a sliding block. The two sides of the sliding block are slidably connected to the outer wall of the guide post, and the middle part of the sliding block is fixedly sleeved on the outer wall of the moving rod.

[0009] Preferably, the positioning and clamping mechanism further includes pulleys that slide in contact with both sides of the triangular block, and a drive seat that is movably connected to the pulleys. The bottom of the drive seat is connected to a drive block, which is slidably connected to a drive slide rail. The drive slide rail is installed on the button test bench. The top of the drive seat is fixedly connected to a clamping seat, on which a clamping clamp arm is installed.

[0010] Preferably, a stop seat is also installed on one side of the drive slide rail, and a stop rod is installed on one side of the stop seat. The other end of the stop rod extends into the interior of the drive seat, and a compression spring is sleeved on the outer wall of the stop rod. One end of the compression spring is fixed on the stop rod, and the other end is connected to the drive seat.

[0011] This utility model provides a positioning and clamping fixture for button testing. It has the following advantages:

[0012] (1) When the cylinder drives the moving rod to move back and forth, the sliding block will slide along the guide post. During this process, the other end of the moving rod drives the triangular block to move synchronously, and the pulley slides on the triangular block, thereby driving the drive seat to move back and forth along the drive slide rail, so as to achieve precise positioning of the test button. In this way, the testing efficiency is improved and the accuracy of the test is ensured. With the reciprocating motion of the cylinder, the accuracy of the test bench is improved, ensuring that the test of each button meets the design requirements.

[0013] (2) In this utility model, when the sliding block slides along the guide post, the spring plays a role in adjusting and buffering the speed, ensuring the stability of the clamping fixture when clamping and releasing the test button. When the drive seat moves back and forth along the drive slide rail, the compression spring plays a role in buffering the speed, ensuring that the button will not be damaged due to excessive clamping force during the test. The entire fixture system achieves precise control and protection of the button through precise design. The combined use of the spring and the dynamic compression spring effectively balances the force transmission during the test, ensuring the accuracy of the test and avoiding excessive pressure on the button.
