[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0026] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes a fixture 100 for use in a touch testing device. This device can test the touch performance of touch devices during the production testing phase, including but not limited to televisions and tablet computers. In this embodiment, the fixture 100 includes a base assembly 10 and a clamping device 20.

[0030] The base assembly 10 includes a mounting plate 11. The mounting plate 11 is designed to support multiple components and therefore requires high structural strength. Therefore, the mounting plate 11 can be made of materials such as aluminum alloy or stainless steel. The mounting plate 11 is provided with a guide portion 111, which is arc-shaped.

[0031] The clamping device 20 includes a connecting component 21 and a clamping mechanism 22. The clamping mechanism 22 is mounted on the connecting component 21. The connecting component 21 can be plate-shaped and has a certain thickness to better connect the clamping mechanism 22 and the mounting plate 11, ensuring connection stability and the stability of the fixture 100 during the testing process, thereby ensuring testing accuracy. Of course, the connecting component 21 can also be in other structural forms, such as forming a base with a larger thickness. This application does not limit this.

[0032] The clamping mechanism 22 is used to hold the touch test piece 200, such as a stylus or stylus stick, during the testing process. The stylus can be a passive or active capacitive pen, or an inductive pen, while the stylus stick can be a copper rod, etc., providing good conductivity. By clamping the touch test piece 200 with the clamping mechanism 22, the tester is spared the need to hold the touch test piece 200 by hand, simplifying the testing operation and improving testing accuracy.

[0033] The technical solution of this application uses a connecting component 21 that is slidably connected to a guide portion 111. The connecting component 21 can be adjusted relative to the mounting plate 11 along the extension direction of the guide portion 111. Since the guide portion 111 is arc-shaped, the connecting component 21 can be adjusted along the arc-shaped extension direction of the guide portion 111. The clamping mechanism 22 is installed on the connecting component 21, so the angle of the clamping mechanism 22 relative to the mounting plate 11 is also adjustable. With this configuration, when the base component 10 is fixed in a fixed position, the clamping device 20 can be adjusted to different touch angles to adapt to touch devices of different sizes and shapes, making the fixture 100 more adaptable, improving the flexibility of testing, and ensuring that the test point is aligned with the contact point of the touch device, thereby improving the accuracy of the test data. Furthermore, the slidable connection between the connecting component 21 and the guide portion 111 allows for quick adjustment of the fixture 100, reducing the setup time for adjusting the fixture 100, making the testing process more efficient, and thus improving testing efficiency.

[0034] In some embodiments, the guide portion 111 is formed as an arcuate groove 1111 on the mounting plate 11. The connecting assembly 21 includes a connecting seat 211 and a slider 212 disposed on the connecting seat 211. The clamping mechanism 22 is disposed on the connecting seat 211. The slider 212 slides in cooperation with the arcuate groove 1111 and can slide along the extension direction of the arcuate groove 1111. Through the sliding cooperation between the slider 212 and the arcuate groove 1111, the connecting assembly 21 and the guide portion 111 can be more easily adjusted, the structure of the clamp 100 is simpler, and it is easier for maintenance and testing personnel to use. It should be noted that the arcuate groove 1111 can also be formed on the connecting seat 211, and the guide portion 111 can be provided with the slider 212, which can also achieve the aforementioned sliding cooperation between the slider 212 and the arcuate groove 1111.

[0035] When the clamping mechanism 22 holds the touch test piece 200, the touch test piece 200 has a first end 201 and a second end 202 along its own length. The first end 201 of the touch test piece 200 is located close to the connecting seat 211, and the second end 202 is located away from the connecting seat 211. During the sliding connection between the connecting component 21 and the guide part 111, the first end 201 of the touch test piece 200 can rotate relative to the mounting plate 11 along the extension direction of the arc groove 1111, while the second end 202 of the touch test piece 200 remains unchanged at the original test point position. Thus, the second end 202 of the touch test piece 200 can be used to perform touch tests at different angles on the test point, meeting diverse testing needs. This ensures that during the angle adjustment of the connecting component 21 relative to the mounting plate 11 along the extension direction of the guide part 111, the contact position between the touch test piece 200 and the test point does not shift, thereby further ensuring the accuracy of the test data and greatly improving testing efficiency.

[0036] It is understood that multiple arc-shaped slide grooves 1111 are provided, and these multiple arc-shaped slide grooves 1111 are arranged at intervals along the same direction and are concentrically set. Multiple sliding members 212 are provided, and each arc-shaped slide groove 1111 contains a sliding member 212. By having multiple sliding members 212 slide and engage within the corresponding arc-shaped slide grooves 1111, the contact area between the guide part 111 and the connecting component 21 is increased, thereby improving the stability and load-bearing capacity of the structure. Furthermore, the multiple sliding members 212 provide a redundant design, so even if some sliding members 212 loosen or fall out of the arc-shaped slide groove 1111, the remaining sliding members 212 can still continue to slide and engage within the arc-shaped slide groove 1111, improving the overall reliability of the fixture 100.

[0037] Multiple arc-shaped slide grooves 1111 are arranged at intervals along the same direction and are concentrically set, which can accommodate different testing requirements. Multiple sliders 212 can selectively cooperate with multiple concentric arc-shaped slide grooves 1111 for sliding connection. Furthermore, by adjusting the multiple sliders 212 with different concentric arc-shaped slide grooves 1111, touch test pieces 200 of different lengths can be used, making the fixture 100 more adaptable and able to adapt to different testing requirements and testing environments.

[0038] Please refer to Figure 3 and Figure 4Multiple arc-shaped slides 1111 are arranged at intervals along the same direction and are concentrically set. The angle α1 of each arc-shaped slide 1111 is greater than or equal to 15 degrees and less than or equal to 90 degrees. When the angle α1 of the arc-shaped slide 1111 is less than 15 degrees, the adjustable angle range of the arc-shaped slide 1111 is small and cannot well adapt to the needs of different test angles. When the angle α1 of the arc-shaped slide 1111 is greater than 90 degrees, the area of ​​the guide part 111 will be large, which will make the overall space occupied by the fixture 100 larger and not conducive to flexible operation.

[0039] Therefore, the value of α1 can be 15 degrees, 30 degrees, 50 degrees or 90 degrees, etc., and the α1 of each arc groove 1111 can be the same or different. In the embodiment of this application, the α1 of each arc groove 1111 is the same, which can ensure that each test is carried out under the same conditions, thereby improving the repeatability of test results and the accuracy of test data, and improving the efficiency of touch test.

[0040] In one embodiment, the sliding element 212 is a rolling bearing. A rolling bearing is a precision mechanical component that works by reducing friction through the rolling of rolling elements (balls, needle rollers, or rollers) between the inner and outer rings, thereby reducing energy loss and wear. A rolling bearing consists of an inner ring, an outer ring, rolling elements, and a cage. It has a low coefficient of friction and inertia, enabling it to provide higher speeds and greater load capacity, and also possesses self-aligning properties. It can simultaneously withstand combined radial and thrust loads, has standardized dimensions, is interchangeable, easy to install and disassemble, convenient to operate, easier to maintain, and has lower production costs.

[0041] The rolling bearing extends into the arc groove 1111. The rolling bearing reduces friction and wear by rolling, resulting in low frictional resistance and fast start-up. This helps to improve the service life of the sliding part 212 and the arc groove 1111, achieving efficient cooperation between the sliding part 212 and the arc groove 1111. It also makes the connection structure between the guide part 111 and the connecting assembly 21 compact, lightweight, and with a small axial dimension, making the fixture 100 lighter overall, reducing the overall size and weight of the fixture 100, and facilitating operation by testing personnel.

[0042] In some embodiments, the connecting assembly 21 further includes a locking member 213, which is detachably and fixedly connected to the mounting plate 11 and used to lock the connecting seat 211 relative to the mounting plate 11 after the connecting assembly 21 has been slidably adjusted. The locking member 213 can be a quick-locking screw, which typically uses a spring and a wedge mechanism to ensure that each locking operation applies the same force to lock the connecting assembly 21 onto the mounting plate 11, thereby ensuring consistent clamping force. Furthermore, it allows for quick locking, installation, and disassembly without the use of traditional tools, providing reliable fixation for the connecting assembly 21 after slid adjustment, preventing angular torsion of the connecting assembly 21, ensuring testing accuracy, and improving the reliability and convenience of testing operations. In practical applications, different types and sizes of quick-locking screws can be selected based on the width of the arc groove 1111 to adapt to different usage requirements. It is understood that the locking member 213 can also be a wedge, screw, washer, or other structural forms. This application does not limit the specific form and type of the locking member 213.

[0043] In one specific embodiment of this application, four arc-shaped slide grooves 1111 can be provided, and the four arc-shaped slide grooves 1111 are arranged at intervals along the same direction and are concentrically set. In this way, the area occupied by the guide part 111 will not be too large, and the diversity of movable adjustable positions can be guaranteed to meet different test position requirements. Furthermore, multiple sliding members 212 and multiple locking members 213 are respectively spaced through the arc-shaped slide grooves 1111, which can make the connection more stable. During the sliding connection between the connecting component 21 and the guide part 111, sliding deviation and displacement can be prevented, thereby ensuring test accuracy.

[0044] In some embodiments, the mounting plate 11 is further provided with a plurality of first positioning parts 112, and the connecting seat 211 is provided with a second positioning part 2111. The first positioning parts 112 and the second positioning parts 2111 are detachably fixedly connected and used to lock the connecting seat 211 relative to the mounting plate 11 after the connecting component 21 has been slidably adjusted, thereby determining the specific angle of the connecting component 21 after slid adjustment, realizing the limit of further adjustment angle of the connecting component 21, ensuring test accuracy, and thus improving test efficiency. It is understood that the plurality of first positioning parts 112 can also be provided on the connecting seat 211, and the first positioning parts 112 can be provided on the mounting plate 11, which can also realize the relative locking of the connecting seat 211 and the mounting plate 11 after the connecting component 21 has been slidably adjusted.

[0045] The first positioning part 112 consists of multiple positioning holes on the mounting plate 11, which are arranged along the extension direction of the guide part 111 and spaced apart from each other. The second positioning part 2111 is a positioning pin connected to the connecting seat 211. The positioning pin can be made of hard steel and heat-treated to improve its wear resistance and strength. The positioning holes and the arc-shaped slide groove 1111 are spaced apart, and the multiple positioning holes are arranged at intervals along the extension direction of the arc-shaped slide groove 1111. The positioning pin can be selectively inserted into one of the multiple positioning holes, thereby restricting the degree of freedom of the connecting component 21. By utilizing the precise fit between the two, accurate angle adjustment can be achieved, and rapid positioning can be realized. After the connecting component 21 is slidably adjusted, the tester does not need to measure the adjusted angle, ensuring the accuracy and interchangeability of the adjusted angle, reducing test steps, protecting the accuracy of test data, and thus further improving test efficiency.

[0046] To reduce wear on the locating pin and locating hole, the locating pin can be detachably connected to the connecting seat 211. When the locating pin wears to a certain extent, it can be disassembled and replaced. The type of locating pin can be an indexing pin. Indexing pins are precision components in mechanical engineering, used for axial positioning and indexing. They are characterized by high precision, versatility, durability, and ease of operation. The types of indexing pins can include, but are not limited to, reset type indexing pins, self-locking type indexing pins, handle type indexing pins, etc. Of course, locating pins can also be other types, such as fixed type, replaceable type, diamond pin, etc., to adapt to different application needs. This application does not limit this.

[0047] Along the center direction of the guide portion 111, the graduation of multiple positioning holes is 2 to 10 degrees. With this setting, during the sliding connection between the connecting component 21 and the guide portion 111, the rotation angle of the touch test piece 200 held by the clamping mechanism 22 can be more accurate, avoiding multiple measurements, reducing the positioning error after each sliding connection, thereby improving test accuracy, avoiding displacement, and further improving test efficiency.

[0048] It is understood that the graduation of the positioning hole can be 5 degrees, thereby leaving an appropriate distance between each positioning hole, reducing machining errors, while ensuring multi-angle adjustment and providing more angle possibilities for testing. The graduation of the positioning hole can also be 2 degrees, 4 degrees, 8 degrees, 10 degrees, etc., and this application does not limit it.

[0049] In some embodiments, please refer again Figures 1 to 3The clamping device 20 also includes a positioning member 221. One end of the positioning member 221 is fixedly connected to the connecting seat 211, and the other end extends toward the center of the guide portion 111. The positioning member 221 can be in the form of a plate extending toward the center of the guide portion 111 or in the form of a column. When the clamping mechanism 22 clamps the touch test piece 200, the length direction of the positioning member 221 is parallel to the length direction of the touch test piece 200. That is, the end of the positioning member 221 extending toward the center of the guide portion 111 is close to the second end 202 of the touch test piece 200. With this setting, the second end 202 of the touch test piece 200 can be positioned and detected in the direction toward the center of the guide portion 111, thereby making it easier to determine the actual position of the touch test piece 200 after angle adjustment.

[0050] In one embodiment, the clamping mechanism 22 is further provided with a locking element 222, which includes at least two locking blocks. When the touch test piece 200 is installed on the clamping mechanism 22, the at least two locking blocks can lock and limit the touch test piece 200. Specifically, there are two locking blocks, which are arranged opposite to each other. The two locking blocks cooperate to form a receiving groove 223. The depth direction of the receiving groove 223 is parallel to the length direction of the positioning member 221. The first end 201 of the touch test piece 200 extends into the receiving groove 223 and is locked between the two locking blocks, which can further limit and fix the touch test piece 200, ensuring that the contact position of the second end 202 of the touch test piece 200 is kept at the actual test point position, thereby ensuring test accuracy and improving the efficiency of touch testing.

[0051] The clamping mechanism 22 is also provided with at least two connectors 225. The at least two connectors 225 pass through the two clamping blocks and are perpendicular to the groove depth direction of the receiving groove 223. When the first end 201 of the touch test piece 200 extends into the receiving groove 223 and is clamped between the two clamping blocks, the connectors 225 can further limit and fix the connection in the length direction perpendicular to the touch test piece 200 to prevent the clamping from loosening or shifting and to increase the clamping force. The clamping force after the two clamping blocks are connected can also be adjusted according to the specific diameter of the touch test piece 200, thereby further ensuring the test accuracy and improving the efficiency of touch testing.

[0052] Specifically, connector 225 can be a handle screw, which typically consists of a screw and a matching nut. One end of the screw is threaded and can be screwed into the nut or other threaded holes, while the other end is equipped with a handle for easy manual operation. This facilitates quick installation and disassembly and adapts to various usage environments. The specific type of handle screw can include, but is not limited to, hex head screws, T-type handle screws, adjustable handle screws, or socket head cap screws. Of course, connector 225 can also be other types, such as screws, bolts, or pins; this application does not limit its application in this regard.

[0053] In addition, a gasket 224 is provided between the two blocks. The gasket 224 can be made of metal or cotton. The gasket 224 ensures the sealing and stability of the connection, reduces the friction between the part of the touch test piece 200 that extends into the receiving groove 223 and the groove wall of the receiving groove 223, thereby reducing wear, extending service life, ensuring accuracy, and having a simple structure that is easy to clean and maintain, reducing repair and replacement costs.

[0054] In another embodiment, the clamping mechanism 22 can also be a three-jaw chuck. A three-jaw chuck is a commonly used machine tool fixture 100, mainly used for clamping cylindrical or similar shaped workpieces. Its working principle is based on the synchronous movement of the three jaws to achieve automatic centering and clamping of the workpiece. The three-jaw chuck consists of a chuck body, movable jaws, and a jaw drive mechanism. By turning the small bevel gear with a wrench, the large bevel gear is driven to rotate, so that the three jaws simultaneously move closer to or retract from the center to clamp or release the workpiece. The self-centering accuracy of the three-jaw chuck is generally between 0.05 and 0.15 mm, suitable for machine tools such as lathes and grinding machines, and provides high clamping accuracy in machining processes such as precision turning, grinding, and milling.

[0055] The three-jaw chuck has two types of jaws: positive jaws and negative jaws. Positive jaws are suitable for workpieces with smaller diameters, while negative jaws are suitable for workpieces with larger diameters. The three-jaw chuck is used to clamp touch test pieces 200. By changing the jaws, it can accommodate touch test pieces 200 of different diameters. Clamping is convenient, fast, and highly accurate. Furthermore, the three-jaw chuck's rapid clamping and automatic centering features also help improve testing efficiency.

[0056] In some embodiments, a camera device 30 is also included, mounted on the base assembly 10, for capturing and measuring the relative position angle of the touch test piece 200 when it is clamped on the clamping device 20. The camera device 30 can be an industrial camera, capable of high-speed capturing images of the touch test piece 200 on the clamping device 20, providing image data for verifying the angular position of the touch test piece 200. Through image analysis, the industrial camera can also detect dimensional deviations of the touch test piece 200, ensuring that the touch test piece 200 remains at the same position as the actual test point on the touch device under test, providing visual feedback to the touch testing device, enabling the touch testing device to perform precise operations. It can also be used to measure the size and specific positioning of the touch test piece 200, improving testing accuracy, and achieving automated detection, measurement, identification, precise positioning and guidance, visual recognition and tracking. It is used for real-time monitoring, data collection, image processing, and automatic decision-making, helping to improve testing efficiency, reduce costs, and improve quality.

[0057] In some embodiments, the base assembly 10 further includes a connecting flange 12 for mounting to the robotic arm. Both the camera device 30 and the mounting plate 11 are mounted on the connecting flange 12. For the camera device 30, which is an industrial camera, the flange distance is a critical parameter, determining whether the lens and camera can focus correctly, thus affecting image clarity. Matching the flange distance is crucial for the proper use of the camera and lens. Only when the flange distances of the lens and camera correspond can light be focused onto the camera sensor, resulting in a clear image. The mounting of both the camera device 30 and the mounting plate 11 on the connecting flange 12 allows for the connection between the relatively stationary mounting plate 11 and the robotic arm, which needs to perform rotational or reciprocating movements. This design facilitates easy disassembly, provides high connection strength, good sealing performance, and lower cost.

[0058] This application also proposes a touch testing device, which includes a robotic arm and a fixture 100. The specific structure of the fixture 100 is as described in the above embodiments. Since this touch testing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] This touch testing equipment can test the touch performance of touch devices during the production and testing phase of touch devices, including but not limited to touch-screen TVs, tablets, and other touch display devices. The fixture 100 is mounted on a robotic arm, automating touch testing, improving testing accuracy, reducing labor costs, and making it suitable for various touch testing environments, thus significantly improving touch testing efficiency. It is understood that the robotic arm can be a three-degree-of-freedom robotic arm, with lower load and simpler motion paths, resulting in higher smoothness; or it can be a six-degree-of-freedom robotic arm, offering greater flexibility and enabling movement in more directions and angles to meet more testing needs. Furthermore, the fixture 100 can be mounted on the robotic arm by means of a connecting flange 12, or by screws, snap-fits, or other methods; this application does not impose any restrictions on this.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application.
