Description

Technical Field

[0001] This utility model relates to the field of roller testing technology, specifically a roller rolling force measuring device. Background Technology

[0002] The rolling force (forward and reverse) of a scroll wheel (such as a mouse scroll wheel or a car steering wheel scroll wheel) directly affects the feel of the user's operation. Traditionally, the rolling force of the scroll wheel is determined by manually rotating it. This method is highly subjective, has poor repeatability and reproducibility, and cannot accurately determine the rolling force (forward and reverse) of the product.

[0003] A mouse scroll wheel force detection device, disclosed in publication number CN207215339U, includes a base, a control button on the side of the base, a vertical guide post fixed to the upper surface of the base, a movable slider mounted on the vertical guide post and sliding up and down along the vertical guide post, a friction test surface for contacting the mouse scroll wheel, a display for displaying the mouse scroll wheel force fixed to the movable slider, a positioning fixture for fixing the mouse, and a carrier. A movable guide rail is provided on the upper surface of the base, the carrier is movably mounted within the movable guide rail, and a pressure sensor is mounted on the movable slider. The pressure sensor is connected to the display via a signal line. This device can accurately detect the scroll force of the entire product rotation, improving the defect detection rate of the tested product, automatically detecting defective products, preventing defective products from reaching the customer, and improving customer satisfaction.

[0004] Existing technologies can automatically detect the rolling force of rollers, but they cannot control the downward pressure of the rollers. Therefore, we propose a roller rolling force measuring device. Utility Model Content
