Description

Technical Field

[0001] This invention relates to the field of VR glasses testing equipment technology, specifically to a VR glasses motherboard testing fixture and its testing method. Background Technology

[0002] VR headsets, or virtual reality head-mounted display devices, were formerly known as VR glasses or VR helmets. VR headsets use a head-mounted display device to block out a person's vision and hearing from the outside world, guiding the user to feel as if they are in a virtual environment. The display principle is that the left and right screens display images for the left and right eyes respectively; after the human eye receives this differentiated information, it creates a sense of depth in the brain.

[0003] During the VR glasses manufacturing process, the VR glasses' motherboard needs to be tested. However, ordinary fixtures make the testing process very cumbersome, and can only test one VR glasses' motherboard at a time. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a test fixture for the motherboard of VR glasses and its testing method are provided to solve the problem that existing test fixtures for the motherboard of VR glasses cannot perform batch testing and have low testing efficiency.

[0005] To achieve the above objectives, a motherboard test fixture for VR glasses is provided, comprising: A base on which a row of pedestals for mounting a motherboard for VR glasses is installed; Two sliding bars are slidably disposed on the base along the row direction of the row of pedestals. The two sliding bars are respectively disposed on opposite sides of the row of pedestals. The base is equipped with a driving mechanism for driving the two sliding bars to move in the same direction. Multiple sliding seats are provided, which slide along the width direction of the sliding strip on the base. A probe is installed on the side of the sliding seat near the base. Multiple pushing members are formed on the sliding strip, and the pushing members have inclined pressure-bearing surfaces. An elastic member is installed on the base and supports the sliding seat so that the sliding seat presses against the pressure-bearing surface. After the main board is installed on the base, the driving mechanism drives the two sliding strips to move in the same direction, and the multiple pushing members push against the sliding seat so that the probes on the multiple sliding seats abut against the main board.

[0006] Furthermore, the two sliding bars are connected by a connecting rod, and the driving mechanism is an electro-hydraulic push rod, which is connected to the base and the connecting rod.

[0007] Furthermore, the row of pedestals is arranged along the length of the base.

[0008] Furthermore, the base has a first sliding groove, which is arranged along the length of the base, and the sliding bar has a first slider, which slides in the first sliding groove.

[0009] Furthermore, the base is provided with a second sliding groove, which is arranged along the width direction of the base, and the sliding seat is formed with a second slider, which slides in the second sliding groove.

[0010] Furthermore, the elastic element is connected between the second slider and the groove wall of the second groove.

[0011] Furthermore, the pedestal has a guide hole, and the sliding seat has a guide rod, which is movably inserted into the guide hole.

[0012] This invention provides a method for testing the motherboard of VR glasses using a motherboard testing fixture, comprising the following steps: The motherboards of multiple VR glasses are mounted on a row of stands; The drive mechanism drives the two sliding bars to move in the same direction. Multiple pushers on the two sliding bars push against multiple sliding seats so that the probes on the multiple sliding seats abut against the motherboard, so that the multiple motherboards are connected to the host computer through the probes. The host computer acquires detection data from multiple motherboards via the probe. The beneficial effect of the present invention is that the VR glasses motherboard testing fixture of the present invention, by setting a row of multiple platforms on the base and cooperating with a sliding bar and multiple sliding seats that can move synchronously, can simultaneously abut multiple probes against the motherboards of multiple VR glasses, thereby realizing simultaneous testing of multiple motherboards, achieving batch testing, greatly improving testing efficiency, and solving the problem that existing fixtures can only test one motherboard at a time and have low testing efficiency.

[0013] The VR glasses motherboard testing fixture of the present invention uses a drive mechanism to drive two sliding bars to move in the same direction. The inclined bearing surface on the pusher cooperates with the sliding seat to convert the linear motion of the sliding bars into the lateral feeding motion of the sliding seat. The structure is ingenious and the transmission is smooth, which can ensure that multiple probes synchronously and accurately abut against the motherboard. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figures 1 to 3 As shown, the present invention provides a motherboard testing fixture for VR glasses, including: a base 1, a slider 2, and a slider 3.

[0021] In this embodiment, the base is cuboid in shape. A row of pedestals 11 is mounted on the base 1. The row of pedestals 11 includes multiple pedestals. The pedestals 11 are used to mount the motherboard of the VR glasses. The multiple pedestals 11 are arranged in a row. Specifically, the multiple pedestals are arranged at equal intervals along the length of the base.

[0022] There are two sliding bars 2. The sliding bars 2 are slidably mounted on the base 1 along the row direction of the pedestals 11. Each sliding bar is positioned along the length of the base. The two sliding bars 2 are respectively positioned on opposite sides of the row of pedestals 11. The base 1 is equipped with a drive mechanism 4. The drive mechanism 4 is used to drive the two sliding bars 2 to move in the same direction, that is, the drive mechanism is used to drive the two sliding bars to move simultaneously toward one end or the other end of the base.

[0023] There are multiple sliding seats 3. In this embodiment, there are six sliding seats. One sliding seat is provided between each base and the sliding bar. The number of sliding seats is adapted to the number of bases. The sliding seat 3 is slidably disposed on the base 1 along the width direction of the sliding bar 2, that is, the sliding seat can slide along the width direction of the base.

[0024] A probe 31 is installed on the side of the sliding base 3 near the platform 11. The probe is connected to a host computer via a wire. The host computer issues test commands and obtains test data from the motherboard through the probe to determine whether the motherboard is qualified.

[0025] Multiple pushing members 21 are formed on the sliding bar 2. Each pushing member 21 has a pressure-bearing surface 210. The pressure-bearing surface 210 is inclined. An elastic member 12 is mounted on the base 1. The elastic member 12 is supported on the sliding seat 3 so that the sliding seat 3 presses against the pressure-bearing surface 210.

[0026] See Figure 2 As shown, a reaction rod 34 is vertically mounted on the sliding seat, and the reaction rod presses against the bearing surface.

[0027] After the motherboard is mounted on the base 11, the drive mechanism 4 drives the two sliding bars 2 to move in the same direction. Multiple pushers 21 push against the sliding seats 3 so that the probes 31 on the multiple sliding seats 3 come into contact with the motherboard.

[0028] In this embodiment, the drive mechanism is installed at one end of the base. The drive mechanism simultaneously drives two sliding bars to slide towards the other end of the base. Under the force of the pressure surface pressing against the reaction rod, the probes on the sliding seats on opposite sides of the platform abut against the motherboard mounted on the platform. Then, a test command is issued by the host computer, and test data of the motherboard is obtained through the probes.

[0029] In a preferred embodiment, two sliding bars 2 are connected by a connecting rod 22. The connecting rod is located at one end of the sliding bar. The drive mechanism 4 is an electro-hydraulic push rod. The electro-hydraulic push rod is connected to the base 1 and the connecting rod 22.

[0030] An electro-hydraulic actuator is arranged along the length of the base. The actuator has a fixed end and a telescopic end. The fixed end of the actuator is mounted to one end of the base. The telescopic end of the actuator is connected to a connecting rod. After the actuator extends, the two sliding bars slide towards the other end of the base.

[0031] In this embodiment, a row of pedestals 11 is arranged along the length of the base 1. The base 1 has a first sliding groove. The first sliding groove is arranged along the length of the base 1. A sliding bar 2 has a first slider. The first slider is slidably disposed in the first sliding groove.

[0032] In some embodiments, a groove is formed on the slider, and correspondingly, a slider is formed on the base. The slider is slidably disposed in the groove, allowing the slider to slide along the length of the base.

[0033] See Figure 3 As shown, the base 1 has a second sliding groove. The second sliding groove is provided along the width direction of the base 1. The sliding seat 3 has a second slider 33. The second slider 33 slides in the second sliding groove.

[0034] In a preferred embodiment, the elastic element 12 is connected between the second slider 33 and the groove wall of the second groove.

[0035] In this embodiment, the elastic element is a spring. The spring is connected to the groove wall at one end of the second slider and the second slide groove. When the slider moves towards the other end of the base, the sliding seat moves towards the platform. At this time, the spring is compressed and accumulates elastic potential energy. When the slider moves towards the end of the base, the spring releases its elastic potential energy, pushing the sliding seat towards the slider, thus resetting the sliding seat.

[0036] Continue reading Figure 2 As shown, the base 11 has a guide hole. The sliding seat 3 has a guide rod 32. The guide rod 32 is movably inserted into the guide hole. Through the insertion and engagement of the guide rod and the guide hole, the probe is ensured to accurately abut against the main board.

[0037] This invention provides a method for testing the motherboard of VR glasses using a motherboard testing fixture, comprising the following steps: S1. Install the motherboards of multiple VR glasses onto a row of bases 11.

[0038] S2, the drive mechanism 4 drives the two sliding bars 2 to move in the same direction, and the multiple pushers 21 on the two sliding bars 2 push against the multiple sliding seats 3 respectively so that the probes 31 on the multiple sliding seats 3 abut against the motherboard, so that the multiple motherboards are connected to the host computer through the probes 31.

[0039] S3. The host computer obtains detection data from multiple motherboards through probe 31.

[0040] The VR glasses motherboard testing fixture of the present invention, by setting a row of multiple platforms on the base and cooperating with a synchronously movable slider and multiple sliding seats, can simultaneously abut multiple probes against the motherboards of multiple VR glasses, thereby realizing simultaneous testing of multiple motherboards, achieving batch testing, greatly improving testing efficiency, and solving the problem that existing fixtures can only test one motherboard at a time and have low testing efficiency.

[0041] The VR glasses motherboard testing fixture of the present invention uses a drive mechanism to drive two sliding bars to move in the same direction. The inclined bearing surface on the pusher cooperates with the sliding seat to convert the linear motion of the sliding bars into the lateral feeding motion of the sliding seat. The structure is ingenious and the transmission is smooth, which can ensure that multiple probes synchronously and accurately abut against the motherboard.

[0042] The motherboard testing fixture for VR glasses of the present invention has an automatic reset function, making it easy to operate. An elastic element is installed on the base of the motherboard testing fixture for VR glasses of the present invention. The elastic element is supported by a sliding seat, which automatically resets when the sliding bar retracts, eliminating the need for manual intervention, facilitating continuous operation, and improving the convenience of the testing process.

[0043] The VR glasses motherboard testing fixture of this invention has high positioning accuracy and reliable test results. The base of the VR glasses motherboard testing fixture of this invention has a guide hole, and a guide rod is formed on the sliding seat. The guide rod is movably inserted into the guide hole, which can accurately guide the movement direction of the probe, ensuring that the probe accurately contacts the test point on the motherboard each time, avoiding misjudgments due to poor contact.

[0044] The VR glasses motherboard test fixture of this invention has a compact structure and low cost. The two sliding bars of the VR glasses motherboard test fixture are connected by a connecting rod and synchronously driven by an electro-hydraulic push rod, reducing the number of driving components, resulting in a compact overall structure, small footprint, and lower manufacturing costs and maintenance difficulty.
