Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and particularly relates to a VR handle testing machine. Background Art

[0002] Before leaving the factory, the VR handle needs to perform functional tests on each functional component of the handle. At present, the contact testing equipment in the market can only perform tests on individual functional components. If multiple functional components of the VR handle need to be tested, multiple machines need to be set up, which will increase the floor area of the testing equipment. Moreover, most of the existing VR handles are designed according to ergonomics, and their shapes are mostly irregular curved surfaces, which have problems such as difficult positioning and difficult testing. Summary of the Invention

For this purpose, the present invention provides a VR handle that can effectively position the VR handle, simultaneously detect multiple functions of one handle, and reduce the floor area of the equipment.

A plurality of first driving members are installed at the testing station, and the first pressing heads are respectively connected to the first driving members one by one. The first driving member is used to drive the first pressing head to move towards or away from the positioning groove; the second detection component is located above the carrier.

The first detection component and the second detection component cooperate to monitor and detect the force curves of a plurality of functional components on the outer surface of the VR handle in the same process, realizing comprehensive and efficient functional detection of the VR handle. By setting the positioning groove, on the one hand, the VR handle can be quickly positioned and installed, effectively improving the installation stability of the handle and the positioning accuracy of the handle; on the other hand, the installation groove remains fixed during the detection process, so that the parts to be detected of the VR handle have a relative reference plane, and the first detection component and the second detection component have a stable moving reference system, which can effectively reduce the detection difficulty of the testing machine.

[0030] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0031] Refer to Figures 1 to 8, a VR handle testing machine according to an embodiment of the present invention includes a machine base 100, a carrier 200, a first detection component 300, and a second detection component 400. The machine base 100 mainly consists of a machine table 110 and a base 120. The machine table 110 is installed above the base 120. The machine table 110 is provided with a test station 111 and a control system 130. The control system 130 is electrically connected to each driving component and detection component described later. The base 120 is installed with a power source and a gas source (not shown in the figure) for the operation of the driving component. Each machine table 110 is also provided with a receiving cavity 101, and the receiving cavity 101 is located below the test station 111; The carrier 200 is installed at the test station 111. The carrier 200 is provided with a positioning groove 201 that matches the shape of the VR handle (especially the grip part of the VR handle). The positioning groove 201 is usually machined by a six-axis machine tool according to the product's outer surface; The first detection component 300 includes a plurality of first pressing heads 310. The plurality of first pressing heads 310 are arranged at intervals along the circumference of the test station 111. A plurality of first driving components 320 are installed at the test station 111 (the first driving component 320 is usually set as a servo electric cylinder with simple assembly and high control precision. In addition, the subsequent fifth driving component 431 is also set as a servo electric cylinder. Only the strokes of the components to be controlled are different, and the sizes and powers of the two servo electric cylinders are slightly different. This is specifically stated here and will not be repeated later). And at least part of the first driving component 320 is accommodated in the receiving cavity 101. The first pressing head 310 is connected to the first driving component 320 in a one-to-one correspondence. The first driving component 320 is used to drive the first pressing head 310 to move towards or away from the positioning groove 201; The second detection component 400 is located above the carrier 200. The second detection component 400 includes a second pressing head 410 and a functional component pressure measurement module 420. The second pressing head 410 is located on one side of the functional component pressure measurement module 420 and is inclined towards the positioning groove 201. In the process of detecting the VR handle, the second pressing head 410 is perpendicular to the normal of the inclined surface of the VR handle. The machine base 100 is installed with a multi-axis driving component 430. The second pressing head 410 and the functional component pressure measurement module 420 are respectively connected to the multi-axis driving component 430. The multi-axis driving component 430 is used to drive the second detection component 400 to move towards or away from the positioning groove 201. The machine table 110 is also connected with a dust cover 112. The dust cover 112 covers the carrier 200, the first detection component 300, and the second detection component 400. An opening for loading and unloading the carrier 200 is reserved at the position of the dust cover 112 corresponding to the test station 111.

[0032] It can be understood that when the user uses the testing machine, the VR handle can be first loaded into the positioning slot 201 of the vehicle 200. After the vehicle 200 is in place, the first detection component 300 and the second detection component 400 operate simultaneously. Specifically, multiple first driving members 320 drive the corresponding first pressing heads 310 to move towards the VR handle on the positioning slot 201, so that the first pressing heads 310 gradually increase the pressure on the corresponding functional components, thereby performing pressure detection on multiple functional components to be detected on the side wall of the VR handle. At the same time, the multi-axis driving component 430 drives the second pressing head 410 and the functional component pressure measurement module 420 to move towards the VR handle on the positioning slot 201 from the upper side and directly above the VR handle respectively, so that the second pressing head 410 and the functional component pressure measurement module 420 gradually increase the pressure on the corresponding functional components, thereby performing pressure detection on multiple functional components to be detected on the inclined surface and the top surface of the VR handle. The first detection component 300 and the second detection component 400 cooperate with each other to monitor and detect the force curves of multiple functional components on the outer surface of the VR handle in the same process, realizing comprehensive and efficient functional detection of the VR handle. By setting the positioning slot 201 with fine machining, on the one hand, the positioning slot 201 is fully fitted with the outer shape of the VR handle, which can quickly position and install the VR handle, effectively improving the installation stability of the handle and the positioning accuracy of the handle; on the other hand, the installation slot remains fixed in the detection process, so that the parts to be detected of the VR handle have a relative reference plane, and the first detection component 300 and the second detection component 400 have a stable moving reference system, which is convenient for the first pressing head 310, the second pressing head 410 and the functional component pressure measurement module 420 to quickly and accurately move towards the corresponding functional components, and can effectively reduce the detection difficulty of the testing machine. Integrating the first detection component 300 and the second detection component 400 at the same station can effectively simplify the structure of the testing machine, reduce the floor area of the equipment. The first detection component 300 and the second detection component 400 have clear division of labor, and the pressing heads do not interfere with each other, and the maintenance is simpler, which can effectively reduce the later maintenance cost of the testing machine.

[0033] It should be noted that the first indenter 310, the second indenter 410, and the functional component pressure measurement module 420 are all profiling parts that match the outer shapes of the corresponding functional components to be detected. For example, for the functional components on the side part of the VR handle, if they are buttons with a relatively small area size, the corresponding first indenter 310 is set as a probe-shaped indenter with a relatively small area; if the functional components on the side part of the VR handle are buttons with a relatively large area size, the corresponding first indenter 310 is set as a block-shaped indenter with a relatively large area. And on the side of the block-shaped first indenter 310 facing the vehicle 200, there is a first positioning surface 313 that matches the outer shape of the corresponding functional component. For the functional components on the inclined surface part of the VR handle, if they are circular buttons, the corresponding second indenter 410 is set as a cylindrical indenter. With such a setting, while increasing the contact area of the pressing area (i.e., the contact area between the test indenter and the corresponding functional component) and improving the test stability, it can effectively avoid each indenter from damaging or scratching the housing wall surface around the functional component to be detected on the VR handle, and improve the yield rate of the VR handle finished product. Here, the outer shapes of the first indenter 310, the second indenter 410, and the functional component pressure measurement module 420 are not specifically limited. The user can set the outer shapes of each indenter according to the actual situation, as long as it can ensure that each indenter can stably detect the relevant functional components.

[0034] Furthermore, there are multiple test stations 111. The multiple test stations 111 are arranged at intervals along the X-axis direction (the X-axis, Y-axis, and Z-axis are set as three mutually orthogonal and perpendicular axes in space. In this embodiment, the positive and negative directions of the X-axis can correspond to the left and right directions of the vehicle 200, the positive and negative directions of the Y-axis can correspond to the front and back directions of the vehicle 200, and the positive and negative directions of the Z-axis can correspond to the up and down directions of the vehicle 200). There are multiple sets of the vehicle 200, the first detection component 300, the second detection component 400, and the test stations 111 arranged in one-to-one correspondence. Due to the integrated design, a set of the first detection component 300 and the second detection component 400 are closely arranged around the same test station 111, which can effectively reduce the installation space occupied by a single test station 111 and the corresponding detection component. At this time, by setting multiple test stations 111, on the premise of ensuring that the floor area of the testing machine is relatively small, one testing machine can simultaneously detect multiple VR handles, reducing the time cost of the testing machine for replacing VR handles, greatly shortening the testing time of multiple VR handles, and effectively improving the detection efficiency of the testing machine.

[0035] Refer to Figure 2 and Figure 3It can be understood that a second driving member 210 is installed on the side of the vehicle 200 facing away from the mounting groove (the second driving member 210 is usually set as a telescopic cylinder with simple assembly and convenient control. In addition, the subsequent fourth driving member 240, sixth driving member 440 and seventh driving member 450 are also set as telescopic cylinders. Only due to the different strokes of the components to be controlled, the sizes and powers of the respective telescopic cylinders are slightly different. This is hereby specifically stated and will not be elaborated further hereafter). Although the second driving member 210 is set as a telescopic cylinder, the second driving member 210 usually also has an additional rotating function, that is, the second driving member 210 is set as a telescopic rotating cylinder. The second driving member 210 is connected to a pressing plate 211. The pressing plate 211 is located on one side of the positioning groove 201. A second positioning surface 212 matching the outer shape of the VR handle is provided on the side of the pressing plate 211 facing the positioning groove 201. The second driving member 210 is used to drive the pressing plate 211 to rotate or drive the pressing plate 211 to move towards or away from the positioning groove 201. When the user installs the VR handle, the second driving member 210 first drives the pressing plate 211 to rotate and leave the surface of the positioning groove 201. When the VR handle is loaded into the positioning groove 201, the second driving member 210 drives the pressing plate 211 to rotate and press the VR handle. With the cooperation of the groove wall of the positioning groove 201 and the second positioning surface 212, the positioning and installation of the VR handle are realized. By providing the pressing plate 211, the pressing plate 211 and the vehicle 200 cooperate to clamp the VR handle, which can effectively improve the installation stability of the VR handle and further improve the detection stability of the testing machine.

[0036] It should be added that a positioning post 250 can also be provided on the bottom wall of the positioning groove 201. The positioning post 250 cooperates with various mounting holes on the VR handle, and can quickly position the VR handle, further improving the installation stability of the VR handle. In addition, a limiting block 260 is provided on the side of the vehicle 200 facing the pressing plate 211. The pressing plate 211 is provided with a protruding portion 213 extending towards the vehicle 200. When the pressing plate 211 presses the VR handle, the limiting block 260 and the protruding portion 213 are correspondingly abutted. By providing the limiting block 260 and the protruding portion 213, the limiting block 260 restricts the movement of the protruding portion 213, thereby restricting the excessive extrusion of the pressing block on the VR handle. While ensuring the stable installation of the VR handle, the rejection rate of the VR handle is reduced.

[0037] Refer to Figure 4It can be understood that the vehicle 200 is equipped with a fourth driving member 240. The fourth driving member 240 is connected to an electrical measurement probe 241. The electrical measurement probe 241 is electrically connected to the control system 130. The vehicle 200 is provided with a sliding groove (not shown in the figure) communicating with the positioning groove 201. The electrical measurement probe 241 is disposed through the sliding groove. The fourth driving member 240 is used to drive the electrical measurement probe 241 to enter or leave the positioning groove 201. When the VR handle is fixed by the pressing plate 211, the vehicle 200 rotates to drive the VR handle to rotate, so that the various functional components on the handle correspond to the positions of the respective pressing heads. When the first pressing head 310, the second pressing head 410, and the functional component pressure measurement module 420 are operating, the fourth driving member 240 synchronously drives the electrical measurement probe 241 to enter the positioning groove 201. The electrical measurement probe 241 contacts the contacts of the VR handle in the positioning groove 201, thereby detecting the signals and current transmission of the electrical components inside the VR handle, and determining whether the electrical components of the VR handle are operating normally. By providing the electrical measurement probe 241, during the operation of the testing machine, the electrical measurement probe 241 can detect the operation conditions of the electrical components inside the VR handle, expand the detection range of the testing machine, increase the functionality of the testing machine, and further improve the integration degree of the testing machine.

[0038] Refer to Figure 2 and Figure 5It can be understood that one end of the carrier 200 is rotatably connected to the test station 111, and the other end is located between the multiple first pressure heads 310 and is arranged to be tilted upward, that is, the multiple first pressure heads 310 are arranged at intervals around the tilted upward part of the carrier 200, and the test station 111 is installed with a third driving member 230, and the output end of the third driving member 230 is connected to the carrier 200 to drive the carrier 200 to rotate. After the VR handle is installed and positioned, multiple first pressure heads 310 will perform functional tests on multiple functional components on the side of the VR handle, including the functional components on the side of the gripping part of the VR handle. Obviously, the functional components are located on the side of the VR handle away from the mounting slot, which requires that when the carrier 200 is operating on the test machine, the mounting slot on the carrier 200 is located exactly on one side of the carrier 200, so that the first pressure heads 310 on one side of the carrier 200 and the functional components of the gripping part of the VR handle are relatively positioned (for the convenience of description, the posture of the carrier 200 at this time is set to the measuring posture). Due to the upward center of gravity of the VR handle (that is, the part of the VR handle that is not installed in the positioning slot 201), and interference from components such as the first pressure head 310 and the pressing plate 211, the VR handle is directly loaded in the measuring posture of the carrier 200. The VR handle is difficult to align with the positioning slot 201 and is easy to fall off, resulting in difficulty in loading the product. The carrier 200 is tilted and rotatably connected to the test station 111, which requires loading and replacement. When the VR handle is used, the third driving member 230 drives the carrier 200 to rotate to an angle that is convenient for loading. After loading is completed, the pressure plate 211 presses the VR handle, and the third driving member 230 drives the carrier 200 to rotate to a measuring posture, so as to facilitate the subsequent detection components to detect the VR handle. This arrangement is convenient for users to manually load and unload materials or compatible with a robot (or other material moving components in the VR handle production line, not shown in the drawings) to automatically load and unload the carrier 200. Since the testing machine itself occupies a small area, the automatic steering tilting carrier 200 can greatly improve the adaptability of the testing machine and the entire VR handle production line, and further improve the production efficiency of the VR handle. In addition, since the material moving devices between different VR handle production lines are different, the inclination angle of the carrier 200 that needs to be set to cooperate with the material moving device is also different. The inclination angle of the carrier 200 is not specifically limited here, as long as it is convenient for the VR handle to load materials, and the VR handle is positioned so that it will not fall when the pressure plate 211 is not pressed.

[0039] It should be noted that the third driving member 230 can be configured as a telescopic cylinder. In this case, a rotating shaft 220 is provided at one end of the carrier 200, and the rotating shaft 220 is connected to a gear 221. A rack 231 meshing with the gear 221 is installed at the output end of the third driving member 230. The third driving member 230 drives the rack 231 to move along the X-axis direction and then drives the carrier 200 to rotate through the gear 221. In this way, the overall structure of the third driving member 230 is relatively vertical to the overall structure of the carrier 200, which can facilitate the user to assemble the carrier 200 and make full use of the storage cavity 10 in the machine 110. 1, effectively improving the structural rationality and rotation stability of the vehicle 200; the third driving member 230 can also be set as a driving motor (not shown in the figure). In this case, one end of the vehicle 200 is provided with a rotating shaft 220, and the output end of the third driving member 230 is directly connected to the rotating shaft 220. This setting can effectively improve the control accuracy of the vehicle 200 and further facilitate the adaptation of the vehicle 200 to the production line of the VR handle. The structure of the third driving member 230 is not specifically limited here, and the user can set it according to the actual situation, as long as it can stably drive the vehicle 200 to rotate.

[0040] Furthermore, the test station 111 is equipped with a photoelectric sensor 140, which is located on the side of the carrier 200 away from the third driving member 230, and the detection end of the photoelectric sensor 140 and the positioning slot 201 are located on the same side of the carrier 200 (because the carrier 200 needs to be rotated before operation to facilitate the loading of the VR handle, the installation slot rotates with the rotation of the carrier 200. Therefore, in this embodiment, the position of the detection end of the photoelectric sensor 140 uses the position of the positioning slot 201 when the carrier 200 is in a measuring posture, that is, when the testing machine is in an operating state as a reference benchmark. This is specially explained here to avoid misunderstanding). When the VR handle is fixed by the pressure plate 211, the rotation of the carrier 200 drives the VR handle to rotate. When the carrier 200 rotates to the measuring posture, that is, the installation slot is located on one side of the carrier 200, the part of the VR handle that is not installed in the positioning slot 201 also rotates to the side of the carrier 200. At this time, since the detection end of the photoelectric sensor 140 and the installation slot of the measuring posture are on the same side of the carrier 200, the photoelectric sensor 140 can detect that there is an object (that is, the part of the VR handle that is not installed in the positioning slot 201) blocking it at a close distance, and then determine that the carrier 200 has been loaded with the VR handle and is in the measuring posture, and then each pressure head starts to work synchronously. By setting the photoelectric sensor 140, it can play a role in detecting the presence or absence of a product and determining whether the product is in a state to be tested, thereby avoiding problems such as energy waste caused by the carrier 200 being empty, and effectively improving the continuity and smoothness of the test machine's detection.

[0041] Reference Figure 2 and Figure 6, It can be understood that a spring buffer 330 is connected to the output end of the first driving member 320. The spring buffer 330 corresponds to the first indenter 310 one by one. Among them, one of the first indenters 310 is set as a capacitance detection indenter 311. The capacitance detection indenter 311 is connected to the spring buffer 330, and the remaining first indenters 310 are set as pressure detection indenters 312. The pressure detection indenter 312 is connected to a pressure sensor 340. The pressure sensor 340 is connected to the spring buffer 330 and electrically connected to the first driving member 320. The capacitance detection indenter 311 continuously presses the corresponding functional component. Inside the product, according to the change of the external force, the change of the capacitance value of the corresponding area of the product is read and sent to the control system 130; the pressure detection indenter 312 continuously presses the corresponding functional component, and the external force continuously increases. The control system 130 monitors and detects the force curve of the product, divides the first detection component 300 into a capacitance detection indenter 311 and a pressure detection indenter 312, performs corresponding function detections on different functional components of the VR handle, further expands the detection range of the testing machine, increases the functionality of the testing machine. A spring buffer 330 is provided at the output end of the first driving member 320, so that the abutting pressure when the first indenter 310 contacts the functional component is buffered by the buffer, reducing the impact on the functional component, effectively improving the detection accuracy of the testing machine, and further reducing the rejection rate of the VR handle finished product. In addition, since the functional components that require pressure detection have high requirements for sensing accuracy and are difficult to test, by setting the pressure sensor 340, when the pressure detection indenter 312 presses the functional component, the pressure sensor 340 continuously detects the feedback force of the functional component and outputs the feedback to the first driving member 320, so as to accurately adjust the pressure of the pressure detection indenter 312. While meeting the high requirements of the functional component for sensing accuracy, the output force adjustment of the indenter is simple and easy, and the output is stable and efficient, which can effectively reduce the testing difficulty of pressure detection.

[0042] Refer to Figure 5 and Figure 6 , It should be added that among the functional components for which the first indenter 310 performs pressure detection, in addition to the traditional button-type components, there may also be trigger-type components and back-key-type components. In order to conform to ergonomics and facilitate the user to pull with the index finger when holding the VR handle, these components are usually arranged at the front end of the VR handle and hinged to the main body of the VR handle. In order to stably push and detect such functional components, at least one first indenter 310 (or pressure detection indenter 312) is arranged opposite to the carrier 200 and inclined upward. Such an arrangement ensures that each first indenter 310 can fit different types of functional components, further improving the detection stability of the testing machine.

[0043] Refer to Figure 7 and Figure 8, it can be understood that the multi-axis drive assembly 430 includes a fifth drive member 431, a first linear module 432 arranged along the X-axis direction, and a second linear module 433 arranged along the Y-axis direction. The second linear module 433 is installed on the machine base 100. The output ends of the first linear module 432 and the second linear module 433 are connected. The output end of the fifth drive member 431 is connected to the output end of the first linear module 432. The second detection assembly 400 is connected to the output end of the fifth drive member 431. The first linear module 432 is used to drive the second detection assembly 400 to move along the Y-axis direction. The second linear module 433 is used to drive the second detection assembly 400 to move along the X-axis direction. The fifth drive member 431 is used to drive the second detection assembly 400 to move along the Z-axis direction. The first linear module 432, the second linear module 433, and the fifth drive member 431 cooperate to drive the second detection assembly 400 to move towards or away from the positioning groove 201 in the three-dimensional space. Since both the linear module and the servo electric cylinder have the advantages of simple assembly, high control accuracy, etc., such a setting can simplify the structure of the multi-axis drive assembly 430, facilitate the user to control or maintain the multi-axis drive assembly 430, make the testing machine mechanism simpler and more compact, and more convenient for maintenance.

[0044] Furthermore, the functional component pressure measuring module 420 includes a third pressure head 421 and a rocker pressure head 422 (i.e., a 360° elastic buffer centering pressure head), the third pressure head 421 and the output end of the fifth driving member 431 are fixedly connected, the rocker pressure head 422 and the fifth driving member 431 are slidingly connected, the fifth driving member 431 is installed with a sixth driving member 440, and the output end of the sixth driving member 440 is connected to the rocker pressure head 422 to drive the rocker pressure head 422 to move along the Z-axis direction. When the vehicle 200 is in the measuring posture, the VR handle is in the upright position (that is, the VR handle is loaded onto the vehicle 200 in a side-lying posture). At this time, the joystick and interactive buttons (both common functional components) on the top surface of the VR handle are located below the functional component pressure measurement module 420. Since the VR handle is usually provided with only one joystick but multiple interactive buttons, when detecting the joystick, the multi-axis driving component 430 is required to drive the joystick pressure head 422 to rotate in the XY plane. When detecting multiple interactive buttons, the multi-axis driving component 430 is required to drive the third pressure head 421 to move three-dimensionally above the VR handle. Therefore, it is necessary to set the sixth driving component 440 to independently control the joystick pressure head 422 so that the joystick pressure head 422 can move in three dimensions. 22 can move relative to the third pressure head 421, so as to separately detect the joystick and the interactive button, that is, when detecting the joystick, the sixth driving member 440 drives the joystick pressure head 422 to descend and abut the joystick, and when detecting the interactive button, the sixth driving member 440 drives the joystick pressure head 422 to rise, and the multi-axis driving assembly 430 drives the third pressure head 421 to abut the interactive button (in the same detection process, there is usually no rigid requirement for the detection order of the joystick and the interactive button), so as to avoid collision, friction and other problems between the third pressure head 421 or the joystick pressure head 422 and the handle during the detection of the functional components on the top surface of the VR handle, thereby further improving the continuity and smoothness of the detection of the testing machine and improving the yield rate of the finished VR handle.

[0045] Reference Figure 8 It can be understood that the fifth driving member 431 is equipped with a connecting block 434, the second pressing head 410 is connected with an adjusting plate 411, the adjusting plate 411 is provided with a plurality of coaxial arc holes 401, the axis of the arc hole 401 is parallel to the Y axis, and the adjusting plate 411 is connected with a plurality of fasteners (the fasteners are usually provided as common screws, pins and other components, which are not shown in the drawings for the convenience of observation), and the fasteners are correspondingly penetrated through the arc holes 401 and connected with the connecting block 434. The user can rotate the adjusting plate 411 by loosening the fasteners, thereby changing the inclination angle of the second pressing head 410, so that the second pressing head 410 is more suitable for the functional components on the inclined surface of the VR handle. By providing the arc hole 401 and the fasteners, the adjustment range of the second pressing head 410 can be increased. With the detachable pressing heads and the customized finely processed positioning groove 201 of the carrier 200, the applicable scope of the test machine can be expanded, so that the test machine can detect VR handles of different shapes, and effectively improve the product competitiveness of the test machine.

[0046] It should be added that the second indenter 410 is usually slidably connected to the adjusting plate 411. The adjusting plate 411 is provided with a seventh driving member 450. The output end of the seventh driving member 450 is connected to the second indenter 410 to drive the second indenter 410 to tilt and move towards the positioning groove 201. The setting of the seventh driving member 450 mainly has a similar effect to that of the sixth driving member 440, avoiding problems such as collision and friction between the third indenter 421 and the handle during the detection of the functional components on the side of the VR handle. The specific operation process and effect can be referred to the description of the sixth driving member 440 above, and will not be elaborated here. In addition, since the second indenter 410, the third indenter 421, and the rocker indenter 422 all perform pressure detection on the functional components, pressure sensors 340 electrically connected to the corresponding driving members are provided on the second indenter 410, the third indenter 421, and the rocker indenter 422, so as to play the role of real-time detection and adjustment of the pressing force. The specific operation process and effect can be referred to the description of the pressure sensor 340 of the first indenter 310 above, and will not be elaborated here.

[0047] It should also be added that since the outer shapes of VR handles are all made of materials with a soft touch, the materials themselves are easily scratched, and during the detection process, the friction between each indenter and the handle material is likely to generate static electricity and damage the circuit of the handle. Therefore, the first indenter 310, the second indenter 410, the third indenter 421, and the rocker indenter 422 are usually set as conductive silicone parts that match the outer shapes of the corresponding functional components. Since silicone itself has relatively soft and conductive properties, it can effectively protect the VR handle itself, prevent static electricity, and further reduce the rejection rate of VR handle products.
