Detailed Implementation

[0034] The present invention will now be described in detail with reference to Figures 1 to 6.

[0035] A photosensitive ribbon cable measuring instrument, as shown in Figures 1 to 3, includes a dark box and further includes: an opening 201 located on one side of the dark box for the sensing end of the photosensitive ribbon cable to enter; a light-emitting device located inside the dark box for generating light sources 30 of different brightness; a circuit board 40 electrically connected to the photosensitive ribbon cable; a control device 50 electrically connected to both the circuit board 40 and the light-emitting device for controlling the brightness of the light sources 30; and a display device electrically connected to the circuit board 40 for receiving the photosensitive measurement results of the photosensitive ribbon cable and displaying them accordingly. In use, the sensing end of the photosensitive ribbon cable to be measured is placed into the dark box through the opening 201, and then the connecting end of the photosensitive ribbon cable is electrically connected to the circuit board 40. The control device 50 is then adjusted to cause the light-emitting device to emit light sources 30 of different brightness. The sensing end of the photosensitive ribbon cable detects the brightness information inside the dark box and transmits the brightness information to the circuit board 40. The display device receives the relevant information and displays it dynamically. The operation is simple and effectively improves the efficiency and accuracy of quality inspection of photosensitive ribbon cables.

[0036] Specifically, the display device includes an electrically connected display screen 601 and a microcontroller unit (MCU) 602. The MCU 602 receives brightness information detected by the optical sensor cable, processes the brightness information, and then transmits it to the display screen 601. The display screen 601 displays the brightness change of the light source in the dark room between 0% and 100% in real time. Furthermore, the MCU 602 has pre-set judgment rule codes, which can acquire brightness data, perform necessary conversions and calculations on the acquired data, and then perform logical judgments on the processed data according to the preset judgment rules to determine whether the detected optical sensor cable is qualified. Finally, the display screen 601 displays whether the optical sensor cable is qualified or not. For qualified optical sensor cables, it displays "Pass," and for unqualified optical sensor cables, it displays "NG."

[0037] In this embodiment, a positioning element 203 is provided inside the dark box to fix the optical sensing cable. After entering the dark box, the sensing end of the optical sensing cable is fixed at the positioning element 203 to prevent movement of the sensing end during measurement, ensuring that all obtained brightness information originates from the positioning element 203 and reducing errors. The optical sensing cable is reinforced with steel sheets, and the positioning element 203 is made of magnetic material, enabling it to attract the sensing end of the optical sensing cable into the dark box. In some embodiments, the positioning element 203 is located at the top of the dark box, and the light-emitting device is located at the bottom of the dark box.

[0038] In this embodiment, a sealing element 202 is provided at the opening 201 to ensure that no gaps are formed when the optical sensing cable enters the dark box, preventing external light from entering. The sealing element 202 is made of light-absorbing material to further reduce light leakage or contamination from external light. The dark box includes a box body 101 with the opening 201, and a cover 102 is mounted on the box body 101. At least one of the cover 102 and the box body 101 has a magnetic suction element 204 facing the opening 201, ensuring a tight closure between the cover 102 and the box body 101, reducing the entry of external light into the dark box and affecting the measurement results. Furthermore, the magnetic suction element 204 is embedded within the cover 102 or the box body 101, ensuring that there are no gaps at the opening 201 when the cover 102 is closed on the box body 101. The cover 102 and the box body 101 are rotatably connected by a hinge 205, and the cover 102 also has a handle 206 for easy rotation. When the cover 102 is closed to the box 101, the weight of the cover 102 applies pressure to the box 101, further securing the flexible light-sensing cable and ensuring its stable position within the darkroom. Furthermore, the sealing element 202 is a single-sided adhesive black foam to cushion the thickness of the light-sensing cable after it is fixed to the darkroom by the cover 102 pressing down on it. In this embodiment, the thickness of the sealing element 202 is 2mm. The sealing element 202 and the magnetic element 204 are staggered and embedded in the opening of the box 101. The magnetic element 204 and the positioning element 203 are neodymium magnets.

[0039] In this embodiment, as shown in Figure 2, a frame 70 is also included. The top of the frame 70 has a mounting groove. The circuit board 40, display device, and control device 50 are sequentially installed in the mounting groove. The circuit board 40 is placed at the bottom of the mounting groove, and the display device and control device 50 are connected to the top of the circuit board 40. Specifically, the top of the frame 70 is fixed to the bottom of the darkroom. The light-emitting device is a white LED strip composed of 3-5 strong white LEDs. This strip is fixed to the center of the bottom of the darkroom and connected to the circuit board 40 via a flexible circuit board. Furthermore, the circuit board 40 also has several mounting holes 401, with threaded fasteners used to fix the circuit board 40 to the bottom of the mounting groove.

[0040] In this embodiment, as shown in Figures 4 to 6, a glass cover plate 80 is also included, which covers the circuit board 40. The glass cover plate 80 has mounting openings adapted to the display device and the control device 50. During installation, the glass cover plate 80 covers the top of the circuit board 40, protecting the circuit board 40. The control device 50 and the display device are partially exposed through the mounting openings for easy observation and operation. The circuit board 40, the display device, the control device 50, and the glass cover plate 80 constitute a control panel. In this embodiment, a first interface 90 is also included. The connection end of the optical sensing cable is electrically connected to the circuit board 40 through the first interface 90. The connection end of the optical sensing cable is connected to the first interface 90 through DuPont wires and an adapter plate. The glass cover plate 80 has corresponding mounting openings. The first interface 90 is a pin-type design. Specifically, the first interface 90 consists of 2×3P 2.54mm pitch pins, used to connect the IIC communication interface of the optical sensor cable. Since different optical sensor cables often have different IIC interface sequences, the pin-type design of the first interface 90 facilitates flexible adjustment of the IIC interface sequence when detecting different optical sensor cables. It also includes a second interface 100 electrically connected to the circuit board 40. The second interface 100 is a Type-C interface used for PCB board power supply and program upgrades. Specifically, the second interface 100 is located on the outer side of the rack 70. In other embodiments, the second interface 100 includes two locations: one on the outer side of the rack 70 and another on the top of the rack 70. In this case, the glass cover 80 has a mounting opening adapted to the second interface 100 on the top of the rack 70. The circuit board 40 is a PCB board.

[0041] In this embodiment, the control device 50 includes a dimming knob 502, which can be rotated to control the brightness of the light-emitting device to gradually increase or decrease. The control device 50 also includes a switch knob 501.

[0042] The specific testing steps are as follows:

[0043] 1. Connect an external power source via the second interface 100;

[0044] 2. Open the cover 102 of the darkroom, attach the sensing end of the optical fiber cable to be tested to the positioning part 203 of the cover 102, and then close the cover 102 of the darkroom; then connect the connecting end of the optical fiber cable to the first interface 90.

[0045] 3. Turn on the switch knob 501 on the control panel. This is the initial state. In the initial state, the light-emitting device does not emit light, and the display screen 601 shows a brightness of 0%.

[0046] 4. Rotate the dimming knob 502, and the brightness of the light source 30 emitted by the light-emitting device gradually increases. Simultaneously observe the brightness change from 0% to 100% displayed on the screen 601.

[0047] 5. Rotate the dimming knob 502 in the opposite direction. The brightness of the light source 30 emitted by the light-emitting device gradually decreases. Simultaneously observe the brightness change from 100% to 0% on the display screen 601.

[0048] 6. Wait for the judgment result. The microcontroller unit 602 makes a judgment on the relevant information and transmits the judgment result to the display screen 601. The display screen 601 displays Pass or NG.

[0049] 7. Turn off switch knob 501, replace with another optical sensor cable, and repeat the above steps. After all optical sensor cables have been measured, turn off switch knob 501, and then disconnect the external power supply at the second interface 100.
