Problems solved by technology

Obviously, the traditional test equipment is difficult to test non-planar touch screens such as bendable touch screens because the test table moves in a plane; for the tactile force test of touch screens with tactile feedback function, new test equipment is also needed To be done
[0008] (2) Difficulty in testing human-like multi-finger operations
Similarly, the above-mentioned multi-finger complex motion test requires multi-finger dexterity, and traditional touch screen testers do not have these functions

Embodiment 1

[0059] see figure 1 , the test tool used for the function and performance of the touch device is composed of a base component, a sensor component, a multi-finger module component, a drive component and a grid-like connecting rod telescopic mechanism, and is characterized in that: the base component is each of the test tool The substrate on which the components are installed is equipped with a sensor assembly, a multi-finger module assembly and a drive assembly, the sensor assembly is used for contact force measurement during touch testing, the multi-finger module assembly is used for performing touch operations between the test tool and the touch device, and the drive The assembly is used to drive the movement of the multi-finger module assembly on the base assembly, and the telescoping mechanism of the grid-shaped connecting rod is installed on the multi-finger module assembly for transmission between the multi-finger module assemblies.

Embodiment 2

[0061] This embodiment is basically the same as Embodiment 1, and the special feature is: the base assembly is composed of a reference column, two side cover plates and two guide shafts, wherein there is a scale or a scale on the reference column, and the two side covers The plates are installed on both sides of the reference column, and the area of ​​the side cover is larger than the section of the reference column. Two guide shafts are installed between the two side cover plates parallel to the reference column, and the two guide shafts maintain an effective distance. The sensor assembly is composed of a sensor connector and a multi-axis force sensor, wherein the sensor connector is used to connect the multi-axis force sensor to the reference column, and the multi-axis force sensor is not only used to measure the contact force between the test tool and the touch device , and connect the entire test tool to the motion platform. The multi-finger module assembly is composed of ...

Embodiment 3

[0063] figure 1 Shown is a schematic diagram when the number of finger modules in the testing tool for the function and performance of the touch device is five, which is referred to as the five-finger tool here. The five-finger tool is composed of a base assembly, a sensor assembly, a multi-finger module assembly, a drive assembly and a grid-shaped connecting rod telescopic mechanism.

[0064] figure 1 The base assembly shown is the reference for installation of other components of the five-finger tool, and the assembly includes a reference column 11 , two side cover plates 12 and two guide shafts 13 . The reference column 11 is made of an aluminum alloy profile with a rectangular cross-section, which greatly reduces the weight of the five-finger tool while ensuring strength. The guide shafts 13 are respectively arranged on the two sides of the aluminum alloy profile to ensure the compactness of the space.

Abstract

The invention provides a test tool for the function and performance of a touch device. The test tool has the characteristics of multi-finger imitation of human hand and multi-finger joint movement. Structurally, the tool includes several finger modules, and the kinematic relationship is transmitted between the finger modules through a connecting rod telescopic mechanism, which can achieve dynamic control of finger spacing during touch testing. The purpose of this is to improve the test function of the traditional touch screen tester; further, based on the multi-finger flexible movement ability of the test tool, the test tool is installed on the motion platform to perform the test action, which not only solves the problem of multi-form touch screen It is difficult to test the device, and it is also possible to concentrate on completing a variety of individual touch screen tests to improve test efficiency. At the same time, the device can simulate the real touch operation of human fingers, such as contact force changes, finger swipe trajectory deviation, etc., to evaluate touch The user experience of the device when it is touched by human hands to improve product design and assist in the development of multi-finger applications.

Description

technical field [0001] The invention relates to a test tool for the function and performance of a touch device. Background technique [0002] Devices with touch input functions, such as touch screens of electronic equipment, touch pads on notebooks, or handwriting pads connected to computers, are important channels for information interaction between humans and computers. The function and performance of the touch device directly affects the reliability and user experience of the terminal product. [0003] For the sake of brevity, touch screens are used hereinafter in this specification to refer to touch screens, laptop touchpads, and handwriting pads connected to computers, and other touch devices, but the meaning is not limited to touch screens. [0004] With the continuous progress of the touch screen technology itself, the existing touch screen test device has a technical bottleneck, which is manifested in: [0005] (1) Difficulties in testing brought about by the diver...
