Description

Technical Field

[0001] This invention belongs to the field of VR glasses manufacturing technology, specifically relating to a VR eye-tracking assembly machine. Background Technology

[0002] VR (Virtual Reality) glasses consist of a screen, a lens barrel, and various functional modules. Among them, the eye-tracking module is the core component of immersive interaction. The eye-tracking module can improve the user experience to a greater extent and enhance the sense of intelligence and interaction. However, during assembly, the collinearity accuracy between the optical axis of the eye-tracking module and the pupil directly determines the user experience. However, the existing assembly process still has some defects in use.

[0003] First, the existing assembly modules are not perfect in terms of automatic loading and unloading. After the eye-tracking module is installed, it usually needs to be tested to see if the assembly is complete. However, the continuous operation of multiple processes requires large-scale transfer of VR glasses. This large-scale transfer is not only time-consuming and labor-intensive, but also easily leads to damage to the workpiece and occupies a lot of space.

[0004] Secondly, when VR glasses are placed and loaded, their orientation often shifts due to various reasons. This leads to a lot of repositioning during assembly to accommodate the shifted glasses. Even after repositioning, subsequent VR glasses cannot be guaranteed to be delivered in the same orientation and position, resulting in frequent adjustments to the entire assembly process, consuming a lot of time, and also significantly impacting subsequent testing. Summary of the Invention

[0005] The purpose of this invention is to provide a VR eye-tracking assembly machine that can automatically load and unload VR glasses during assembly, automatically align the glasses during loading, and perform multi-station operations to improve the efficiency of VR glasses assembly.

Magnetic positioning plates are fixedly connected to the upper left and right sides of the base plate, and the magnetic positioning plates are in contact with the lower end of the storage basket.

[0009] In a preferred embodiment, two sets of guide grooves are distributed front to back at the lower end of the base plate, and a gap is provided at the upper end of the inner cavity of the front guide groove. The lower end of the storage basket's rotating shaft extends into the middle of the inner cavity of the base plate. The placement part also includes a gear a, which is fixedly connected to the lower end of the storage basket's rotating shaft. The middle of the inner cavity of the base plate is rotatably connected to a rotating rod via a ball bearing. A gear b is fixedly connected to the upper end of the rotating rod, and the outer ring of gear b meshes with the outer ring of gear a. Gear c is fixedly connected to the lower end of the rotating rod, and the outer ring of gear c is placed in the gap at the upper end of the inner cavity of the front guide groove and extends into the upper end of the inner cavity of the guide groove through the gap.

[0010] In a preferred embodiment, the worktable is positioned behind the transport rail and in contact with the rear end of the transport rail. A guide ring is fixedly connected to the upper inner ring of the worktable, and the guide ring is laid in a ring on the upper end of the worktable, positioned below the processing section and the inspection section respectively. A rack is fixedly connected to the outer ring of the guide ring located between the processing section and the transport rail.

[0011] In a preferred embodiment, an annular groove is provided on the upper end of the worktable, and the control unit also includes an electric guide rail. The electric guide rail is fixedly installed at the lower end of the inner cavity of the annular groove, and a drive ring is fixedly connected to the slider in the inner cavity of the electric guide rail. The drive ring is slidably connected in the annular groove on the upper end of the worktable, and a limit plate is fixedly connected to the upper end of the drive ring. A limit groove is provided at the rear end of the base plate, and the limit groove is movably sleeved on the outer ring of the limit plate.

[0012] In a preferred embodiment, the control unit further includes a mounting bracket, which is fixedly installed at the upper center of the workbench, and a vision inspection instrument is fixedly installed in the area below the upper end of the mounting bracket above the pusher.

[0013] In a preferred embodiment, the processing unit includes a mechanical gripper, which is fixedly mounted on the upper rear side of the mounting frame, and a storage rack is fixedly mounted on the upper rear side of the worktable.

[0014] In a preferred embodiment, the detection unit includes a robotic arm, which is fixedly mounted on the upper right side of the mounting frame. A motor is fixedly mounted in the lower cavity of the robotic arm, and a simulated eyeball is fixedly connected to the output shaft of the motor.

[0015] In a preferred embodiment, the detection unit further includes a mounting block, which is fixedly mounted on the upper right side of the workbench. An electric push rod b is fixedly mounted on the upper end of the mounting block. A plug is fixedly connected to the output end of the electric push rod b. The plug passes through the storage basket and connects to the VR glasses. A wire is electrically connected to the lower end of the plug, and the other end of the wire is electrically connected to the middle of the mounting block.

[0016] The technical effects achieved by this invention are as follows: The pusher and return rack of this invention enable automatic loading and unloading during VR glasses assembly. When the transport rail delivers the VR glasses to the entrance of the workbench, the pusher moves backward, pushing the base plate and storage basket backward, and pushing the VR glasses into the workbench for assembly. After the VR glasses are assembled, the pusher moves forward to reset, and the return rack pushes the storage basket forward, allowing the VR glasses to re-enter the transport rail for conveying, thus achieving automatic loading and unloading. The placement and control units of this invention can automatically align the VR glasses during the loading process, facilitating subsequent processing. During use, the control unit detects the orientation of the VR glasses during loading. If the orientation is correct, the device enters its first state, pushing the base plate to move and connecting the guide groove at the rear end with the guide ring. No issues arise during the circular displacement, preventing orientation deviation from affecting subsequent use. If the orientation is opposite to the preset orientation, the device enters its second state. In this state, the pusher will push the base plate to move further back, connecting the guide groove at the front end with the guide ring. During the circular displacement, the gear C in the front guide groove will mesh with the rack, driving the storage basket and VR glasses to rotate 180 degrees to change their orientation for subsequent assembly and testing. The processing and testing units of this invention can perform multi-station operations simultaneously, improving the efficiency and effectiveness of VR glasses assembly. During processing, VR glasses with their orientation adjusted will enter the lower part of the processing unit for assembly. At this time, a new set of VR glasses can be pushed into the workbench to wait for orientation adjustment. The assembled VR glasses will then enter the testing unit for functional testing. Meanwhile, the VR glasses that have completed testing will return to the entrance of the workbench and be discharged through the return rack. This enables automatic loading and unloading of VR glasses while multi-station operations are running synchronously, improving work efficiency. Attached Figure Description

[0023] Please see the appendix Figures 1 to 6 , Figures 8 to 9 As shown, this embodiment provides a VR eye-tracking assembly machine, including: The transport rail 10 is equipped with a pusher frame 13, and a return frame 14 is provided at the rear end of the pusher frame 13. The placement part 20 includes a base plate 21, a storage basket 22 is provided on the upper end of the base plate 21, and two sets of guide grooves 25 are provided on the lower end of the base plate 21. A gear c29 is provided in one set of guide grooves 25 and the gear c29 is connected to the storage basket 22. VR glasses 30, VR glasses 30 are placed in storage basket 22; The control unit 40 includes a worktable 41, which is located behind the transport rail 10. A guide ring 42 is provided on the worktable 41, and a rack 43 is fixedly connected to the guide ring 42. A drive ring 45 is provided on the worktable 41 and is connected to the base plate 21. The machining section 50 is located on the upper rear side of the worktable 41. Inspection unit 60 is located on the upper right side of workbench 41; Among them, the pusher 13 pushes the base plate 21 and VR glasses 30 onto the worktable 41 to contact the drive ring 45. When the base plate 21 and the storage basket 22 move, there are two states. The first state is that the guide groove 25 at the rear end of the base plate 21 contacts the guide ring 42 and moves along the guide ring 42 to the processing section 50 and the detection section 60. Second state: The lower end of the base plate 21 is located at the guide groove 25 and guide ring 42 at the front end, and when moving along the guide ring 42, the gear c29 contacts the rack 43, driving the storage basket 22 to rotate.

[0024] It should be noted that the inner width of the storage basket 22 is compatible with the VR glasses 30; the VR glasses 30 has pre-drilled mounting holes for assembling the eye-tracking module.

[0025] In this embodiment, the transport rail 10 moves the base plate 21 and the storage basket 22 to the area of ​​the pusher 13. At this time, the pusher 13 pushes the storage basket 22 and the VR glasses 30 onto the workbench 41 and connects with the drive ring 45. At the same time, the control unit 40 detects the orientation of the VR glasses 30. If the orientation is the same as the preset orientation, the guide groove 25 at the rear end of the base plate 21 connects with the guide ring 42, and the drive ring 45 drives the base plate 21 and the VR glasses 30 to move along the guide ring 42 to the area below the processing unit 50 and the detection unit 60 for the assembly and testing of the eye tracking module. If the orientation is opposite to the preset orientation, the base plate 21 continues to move backward, so that the front guide groove 25 is connected to the guide ring 42. When the base plate 21 moves on the outer ring of the guide ring 42, the gear c29 in the front guide groove 25 contacts and meshes with the rack 43. The rack 43 drives the gear c29 and the storage basket 22 to rotate, so that the VR glasses 30 rotates 180 degrees for subsequent assembly and testing. After the assembly and testing are completed, the VR glasses 30 will return to the entrance of the workbench 41. At this time, the pusher 13 moves forward, driving the return rack 14 to move the storage basket 22 and the VR glasses 30 back into the transport rail 10 and discharge them.

[0026] Secondly, please refer to it again. Figures 1 to 3 The inner cavity of the transport rail 10 is equipped with a conveyor belt 11, and the bottom plate 21 to be processed is placed on the conveyor belt 11. An electric push rod a12 is fixedly installed in the middle of the front of the transport rail 10. The output end of the electric push rod a12 is fixedly connected to the left side of the front of the pusher frame 13. The rear end of the pusher frame 13 passes through the transport rail 10 and is fixedly connected to a return frame 14. The return frame 14 is slidably connected to the front end of the middle of the worktable 41. A limit sleeve 15 is fixedly connected to the middle of the lower end of the transport rail 10. The middle of the lower end of the pusher frame 13 is movably sleeved in the inner cavity of the limit sleeve 15.

[0027] It should be noted that the pusher rack 13 and the return rack 14 are both provided with arc-shaped grooves on their adjacent sides, which is intended to facilitate the circular rotation of the base plate 21 and avoid affecting the movement of the base plate 21. The distance between the pusher frame 13 and the return frame 14 should be greater than that between the base plate 21 to avoid affecting the movement of the base plate 21; The middle of the transport rail 10 has a gap at the positions of the pusher 13 and the return 14, which is intended to facilitate the pusher 13 and the return 14 to push the base plate 21 to move. The return rack 14 has an L-shaped structure, and the distance between the part that contacts the base plate 21 and the rear end of the return rack 14 is greater than the distance between the drive ring 45 and the transport rail 10. This is designed so that even if the drive ring 45 spans the cavity at the front end of the worktable 41, the return rack 14 can still push the processed VR glasses 30 to unload, thus achieving automatic loading and unloading while multiple workstations can operate simultaneously.

[0028] Preferably, to ensure the safety of the conveyor belt 11 during transportation, an infrared sensor should be installed at the part of the transport rail 10 that contacts the pusher frame 13. Once the pusher frame 13 is detected to move, the conveyor belt 11 should be stopped immediately. The conveyor belt 11 will only be driven to run again when the pusher frame 13 is completely reset, thereby preventing the conveyor belt 11 from continuously transporting and causing the VR glasses 30 to be processed to come into contact with the pusher frame 13.

[0029] In this embodiment, the conveyor belt 11 is used to transport the base plate 21 and the storage basket 22 from the front end of the transport rail 10 to the area of ​​the pusher 13. The pusher 13 moves backward under the drive of the electric push rod a12, pushing the base plate 21 and the storage basket 22 backward to the workbench 41 for operation. After the operation is completed, the VR glasses 30 will return to the entrance of the workbench 41. At this time, the electric push rod a12 drives the pusher 13 to reset, driving the return rack 14 to move forward, pushing the storage basket 22 and the VR glasses 30 back into the transport rail 10 and discharging them, thus realizing automatic loading and unloading.

[0030] Secondly, please refer to it again. Figures 5 to 8 The placement part 20 also includes two sets of charging ports 23, which are respectively located on the front and rear sides of the storage basket 22. One set of charging ports 23 is connected to the power port of the VR glasses 30. Magnetic positioning plates 24 are fixedly connected to the upper left and right sides of the base plate 21, and the magnetic positioning plates 24 are in contact with the lower end of the storage basket 22.

[0031] It should be noted that the two sets of guide grooves 25 at the lower end of the base plate 21 are distributed front and rear, and the upper end of the inner cavity of the guide groove 25 at the front end is provided with a gap. The lower end of the storage basket 22 extends into the middle of the inner cavity of the base plate 21. The placement part 20 also includes a gear a26. The gear a26 is fixedly connected to the lower end of the shaft of the storage basket 22. The middle of the inner cavity of the base plate 21 is rotatably connected to the rotating rod 27 through a ball bearing. The upper end of the rotating rod 27 is fixedly connected to a gear b28. The outer ring of the gear b28 meshes with the outer ring of the gear a26. The gear c29 is fixedly connected to the lower end of the rotating rod 27, and the outer ring of the gear c29 is placed in the gap at the upper end of the inner cavity of the front guide groove 25 and extends into the upper end of the inner cavity of the guide groove 25 through the gap.

[0032] It should be noted that the two sets of charging ports 23 are located on the front and back sides of the storage basket 22 to prevent the VR glasses 30 from being placed randomly in the storage basket 22, which would cause the power connection port to be unable to align with the charging port 23 and affect subsequent testing operations. The lower end of the storage basket 22 should be provided with a magnetic component that is compatible with the magnetic positioning plate 24 (not shown in the figure, and this is a common technical structure in the prior art, so it will not be described in detail). The purpose is to use the magnetic positioning plate 24 to keep the storage basket 22 aligned with the bottom plate 21, so as to avoid affecting subsequent operations and to facilitate the quick positioning and fixation of the storage basket 22 after rotation. The curvature and inner diameter of the guide groove 25 are adapted to the guide ring 42, and the curvature and width of the inner diameter of the two sets of guide grooves 25 are completely the same, only the opening position is different. This is to enable the guide ring 42 to be adapted to the two sets of guide grooves 25, so as to avoid the difference in the inner diameter and width of the guide grooves 25, which would affect the movement of the base plate 21. Gear c29 is provided only in the front guide groove 25 of the two sets of guide grooves 25, which is designed to allow different working states to be entered by controlling the guide ring 42 to contact different guide grooves 25.

[0033] In this embodiment, when the device enters the first state, the guide groove 25 at the rear end has only a smooth inner wall, and rotating along the guide ring 42 will not affect the storage basket 22, thus avoiding interference with the assembly of the VR glasses 30 facing the correct orientation. However, when the device enters the second state, after the guide groove 25 at the front end connects with the guide ring 42, when the base plate 21 moves along the guide ring 42, the gear c29 in the inner cavity of the front guide groove 25 will contact and mesh with the rack 43. In the subsequent circular movement along the rack 43... In the process, gear C29 rolls on the outer ring of rack 43, driving the rotating rod 27 and gear B28 to rotate. Gear B28 then drives gear A26 to rotate. When gear A26 rotates, it drives the storage basket 22 and VR glasses 30 to rotate 180 degrees, so that the orientation of VR glasses 30 is correctly adjusted. The magnetic positioning plate 24 uses magnetic force to quickly position the storage basket 22 on the base plate 21, ensuring the stability and positioning accuracy of VR glasses 30 after the orientation is changed, so as to facilitate the subsequent assembly and testing of the eye tracking module.

[0034] Secondly, please refer to it again. Figures 8 to 12 The worktable 41 is placed behind the transport rail 10 and in contact with the rear end of the transport rail 10. A guide ring 42 is fixedly connected to the upper inner ring of the worktable 41, and the guide ring 42 is laid in a ring on the upper end of the worktable 41, respectively placed below the processing part 50 and the detection part 60. The rack 43 is fixedly connected to the outer ring of the guide ring 42 located between the processing part 50 and the transport rail 10. The upper end of the worktable 41 is provided with an annular groove. The control unit 40 also includes an electric guide rail 44. The electric guide rail 44 is fixedly installed at the lower end of the inner cavity of the annular groove. A drive ring 45 is fixedly connected to the slider in the inner cavity of the electric guide rail 44. The drive ring 45 is slidably connected in the annular groove at the upper end of the worktable 41. A limit plate 46 is fixedly connected to the upper end of the drive ring 45. A limit groove 47 is provided at the rear end of the base plate 21. The limit groove 47 is movably sleeved on the outer ring of the limit plate 46. The control unit 40 also includes a mounting bracket 48, which is fixedly installed in the upper middle part of the workbench 41, and a vision inspection instrument 49 is fixedly installed in the area below the upper end of the mounting bracket 48 above the pusher 13.

[0035] It should be noted that the guide ring 42 is an L-shaped ring with a cross-section, and the rack 43 is installed in the narrower area at the upper end of the guide ring 42. The purpose is to use the L-shaped cross-section structure to reserve space for the gear c29, so as to avoid the gear c29 being unable to contact and mesh with the rack 43, which would affect the use of the device. In addition, the wider area at the lower end is used to limit the range of motion of the base plate 21, so as to avoid the base plate 21 shaking when sliding, which would affect the meshing stability of the rack 43 and the gear c29. A strip groove is provided in the center of the front of the workbench 41, and the lower end of the return rack 14 is slidably connected in the strip groove. The two ends of the guide ring 42, the electric guide rail 44 and the drive ring 45 are located on both sides of the strip groove, so that the return rack 14 can slide through the strip groove, so that when the electric push rod a12 is retracted, the bottom plate 21 can be pushed back through the return rack 14. The length of rack 43 should be sufficient to drive storage basket 22 to rotate 180 degrees. The specific length should be adjusted according to the actual situation, and no limit is set here. Both ends of the guide ring 42 are rounded, and both ends of the guide groove 25 are also rounded, in order to facilitate the connection between the guide ring 42 and the guide groove 25. The limiting plate 46 is an L-shaped structural plate, and the limiting groove 47 is an L-shaped structural groove. The length of the limiting groove 47 should be greater than the distance between the two sets of guide grooves 25. This is to ensure that after the base plate 21 enters the worktable 41, its range of motion is restricted by the limiting plate 46 so that it can be driven to rotate later. The longer limiting groove 47 also avoids affecting the connection between the guide ring 42 and the guide grooves 25 at different positions, thus ensuring the stability of the device operation. The limiting plate 46 can be set in four sets according to the processing requirements, and is evenly distributed on the upper end of the drive ring 45 (not shown in the figure). The purpose is to allow up to four sets of VR glasses 30 to be placed on the upper end of the drive ring 45 at the same time, so that multiple sets of VR glasses 30 can be processed in multiple stations in a cycle, thereby improving the efficiency of the operation. The electric guide rail 44 is an electric drive rail with a ring structure, which is designed to control the rotation of the drive ring 45. The upper end of the mounting bracket 48 is equipped with three sets of long rods, which respectively mount the vision inspection instrument 49, the processing unit 50 and the inspection unit 60; The visual inspection unit 49 is a component for observing the orientation of the VR glasses 30. When the orientation of the VR glasses 30 is opposite to the preset orientation, the control base plate 21 enters the second state to adjust the orientation of the VR glasses 30.

[0036] In this embodiment, the vision inspection device 49 checks the orientation of the VR glasses 30 entering the workbench 41. If it matches the preset orientation, the pusher 13 is controlled to move only a short distance, causing the guide groove 25 at the rear end to contact the guide ring 42 and enter the first state. Subsequently, the electric guide rail 44 is activated, controlling the drive ring 45 and the limit plate 46 to move, driving the base plate 21 and VR glasses 30 to the designated position for assembly and testing of the eye-tracking module. If the orientation of the VR glasses 30 is opposite to the preset orientation, the vision inspection device 49 feeds a signal back to the control system, which then controls the pusher 13 to continue moving backward, causing the guide groove 25 at the front end to contact the guide ring 42 and enter the second state. As the base plate 21 moves along the guide ring 42, the rack 43 drives the storage basket 22 and VR glasses 30 to rotate and adjust to the correct orientation before moving to the designated position for assembly and testing of the eye-tracking module.

[0037] Please refer to it again. Figure 12 The processing unit 50 includes a mechanical gripper 51, which is fixedly installed on the upper rear side of the mounting frame 48. A storage rack 52 is fixedly installed on the upper rear side of the worktable 41.

[0038] It should be noted that a four-axis robotic arm is mounted on the robotic gripper 51, and assembly operations are performed using the robotic gripper 51. The storage rack 52 is used to place the eye-tracking module. The outer edge of the storage rack 52 is provided with a limit strip, and the middle part is provided with a protruding rod, which is designed to facilitate the placement and retrieval of the eye-tracking module and facilitate the assembly operation.

[0039] In this embodiment, the eye-tracking module is placed in the storage rack 52 during use. Then, driven by the control system, the mechanical claw 51 accurately picks up the eye-tracking module from the storage rack 52 and assembles it into the reserved mounting hole of the VR glasses 30.

[0040] Please refer to it again. Figures 13 to 14 The detection unit 60 includes a robotic arm 61, which is fixedly installed on the upper right side of the mounting frame 48. A motor 62 is fixedly installed in the lower inner cavity of the robotic arm 61. A simulated eyeball 63 is fixedly connected to the output shaft of the motor 62. The simulated eyeball 63 is movably sleeved on the lower end of the robotic arm 61 and placed on the outer side of the lower end of the robotic arm 61. The testing unit 60 also includes a mounting block 64, which is fixedly mounted on the upper right side of the workbench 41. An electric push rod b65 is fixedly mounted on the upper end of the mounting block 64. A plug 66 is fixedly connected to the output end of the electric push rod b65. The plug 66 passes through the storage basket 22 and connects to the VR glasses 30. A wire 67 is electrically connected to the lower end of the plug 66. The other end of the wire 67 is electrically connected to the middle of the mounting block 64.

[0041] It should be noted that the simulated eyeball 63 has a semi-circular structure and a built-in simulated pupil. The whole is composed of silicone and a lens, which makes it easy to simulate real eye movements to detect the normal operation of the eye tracking module. The workbench 41 should have built-in cables that are connected to the mains power supply, so as to power the various electrical components on the workbench 41. The lower end of the plug 66 is provided with a T-shaped slider, and the worktable 41 is provided with a matching slide rail. The slider is slidably connected in the slide rail, which is intended to improve the stability of the movement of the plug 66.

[0042] Preferably, in order to ensure that the plug 66 can stably pass through the charging port 23 and connect to the VR glasses 30, a position sensor can be installed on the workbench 41. The purpose is to control the electric guide rail 44 to stop running after the base plate 21 and the VR glasses 30 are moved to the appropriate position, so as to ensure that the plug 66 can be aligned with the charging port 23 and the VR glasses 30.

[0043] In this embodiment, when the base plate 21 moves to the outside of the mounting block 64, the electric actuator b65 pushes the plug 66 through the storage basket 22 and connects it to the power port of the VR glasses 30, energizing and activating the VR glasses 30. Subsequently, the motor 62 starts, driving the simulated eyeball 63 to rotate, simulating real eye movements and detecting whether the eye-tracking module can track the eyeball's movements. If the test is successful, the electric actuator b65 retracts, the plug 66 disconnects from the VR glasses 30, and the VR glasses 30 continues to the next process. If the test fails, the control system records the failure information for subsequent processing.

[0044] The working principle of this invention is as follows: When in use, the conveyor belt 11 is used to transport the base plate 21 and the storage basket 22 from the front end of the transport rail 10 to the area of ​​the pusher 13. The pusher 13 moves backward under the drive of the electric push rod a12, pushing the storage basket 22 and VR glasses 30 backward to the workbench 41 for operation. At this time, the vision inspection instrument 49 checks the orientation of the VR glasses 30 entering the workbench 41. If it matches the preset orientation, the pusher 13 is controlled to move only a small distance, so that the guide groove 25 located at the rear end contacts the guide ring 42 and enters the first state. Then the electric guide rail 44 is started, controlling the drive ring 45 and the limit plate 46 to move, driving the base plate 21 and VR glasses 30 to the designated position for the assembly and testing of the eye tracking module. If the VR glasses 30 are oriented opposite to the preset orientation, the vision detector 49 will send a signal to the control system. The control system will then control the pusher 13 to continue moving backward, causing the guide groove 25 at the front end to contact the guide ring 42 and enter the second state. After the guide groove 25 at the front end connects with the guide ring 42, as the base plate 21 moves along the guide ring 42, the gear c29 in the inner cavity of the front guide groove 25 will contact and mesh with the rack 43. During the subsequent circular movement along the rack 43, the gear c29 will roll on the outer ring of the rack 43, driving the rotating rod 27 and gear b28 to rotate. The gear b28 will then drive the gear a26 to rotate. When the gear a26 rotates, it will drive the storage basket 22 and the VR glasses 30 to rotate 180 degrees, making... After the VR glasses 30 are correctly oriented, they move to the processing unit 50. The robotic gripper 51 picks up the eye-tracking module and assembles it into the VR glasses 30. Then, when the base plate 21 moves to the outside of the mounting block 64, the electric push rod b65 pushes the plug 66 through the storage basket 22 and connects it to the power port of the VR glasses 30, so that the VR glasses 30 is powered on and running. The motor 62 drives the simulated eyeball 63 to rotate, simulating real eye movements and detecting whether the eye-tracking module can track the eye movements. After the test is completed, the VR glasses 30 will return to the entrance of the workbench 41. At this time, the electric push rod a12 drives the pusher 13 to reset, driving the return rack 14 to move forward, pushing the storage basket 22 and the VR glasses 30 back into the transport rail 10 and out.
