Description

Technical Field

[0001] This application relates to the field of LED panel detection technology, and in particular to a detector for LED panels. Background Technology

[0002] Currently, a light panel is an electronic lighting device with LED as the core light source. It is mainly composed of a steel plate powder-coated frame and a high-transmittance PC panel. It features low energy consumption, no flicker, and no noise. Its built-in constant current drive system can ensure stable operation when the voltage fluctuates. It is suitable for lighting needs in public places such as hotels, schools, factories, and hospitals. Some models support customized processing, and the reflector form (such as PC frosted cover or prism cover) and external dimensions can be adjusted according to requirements.

[0003] Regarding the aforementioned technologies, most existing detectors rely on personnel to inspect the LED light panels for functionality (i.e., whether the LED panels are lit or not). When personnel conduct inspections, their eyes are focused on one spot for extended periods, which is also a form of eye stimulation caused by bright light. This can lead to eye problems and damage over time. Furthermore, it can cause drowsiness, dizziness, and blurred vision. This can easily lead to personnel mistakenly placing non-lit LED panels into the qualified category when their consciousness is impaired, greatly reducing quality and error tolerance, and causing many inconveniences for users. Utility Model Content

[0004] The purpose of this application is to provide a detector for LED light panels, which has advantages such as automated monitoring and solves the problems mentioned in the background art.

[0005] The detector for an LED light panel provided in this application adopts the following technical solution: it includes a support plate, a beam frame, a monitoring mechanism, a cable management mechanism, an electrical control box, and a horizontal plate. The monitoring mechanism includes a support frame fixedly connected to one side of the beam frame. A camera is fixedly installed on the side of the support frame, and a PLC programmable controller and an alarm light are fixedly installed on the other side of the beam frame.

[0006] A fixing plate is fixedly connected to the side of the beam frame. An electric push rod is fixedly installed inside the fixing plate. An acrylic top plate is fixedly connected to the bottom end of the electric push rod. A light-shielding plate overlaps the bottom of the acrylic top plate. Four screws are threadedly connected between the inside of the acrylic top plate and the inside of the light-shielding plate.

[0007] By adopting the above technical solution and setting up a monitoring mechanism, after the LED light panel is placed in position, the electric push rod extends, causing the acrylic top plate and light shield to move downwards. The light shield covers the LED light panel, and then the LED light panel is powered on and emits light. The camera captures the image of the lighting status and transmits it to the PLC programmable controller. Finally, the PLC programmable controller analyzes the image according to preset logic and triggers an alarm light and sound alarm when it determines that there is a failure. This structure achieves the effect of replacing manual visual inspection of the lighting by automatically monitoring, avoiding misjudgment caused by visual fatigue and light stimulation, and greatly improving the detection accuracy. The light shield and acrylic top plate work together to shield external light interference and ensure that the image captured by the camera is clear.

[0008] Preferably, a beam frame is fixedly connected to the top of the support plate.

[0009] By adopting the above technical solution and setting up the beam frame, a stable and orderly spatial structure can be formed for the entire equipment, avoiding shaking and displacement of various components due to lack of proper support, and ensuring the overall stability of the equipment during operation.

[0010] Preferably, the top of the support plate is fixedly connected to four guide rails, the interior of the light-shielding plate has four through holes, and each of the four through holes is fixedly connected to a sliding sleeve, which is slidably connected to the surface of the guide rails. The top of each of the four guide rails is fixedly connected to a limiting disc.

[0011] By adopting the above technical solution, and by setting up guide rails and sliding sleeves, when the electric push rod moves the light shield downward, the sliding sleeve slides along the guide rail, restricting the light shield to only move vertically up and down. The limiting disc is fixed at the top of the guide rail to prevent the light shield from detaching from the guide rail. This ensures that the relative positions of the light shield, LED light panel, and camera are absolutely consistent during each test, avoiding detection errors caused by misalignment of the LED light panel and offset of the light shield.

[0012] Preferably, the surface of the electrical control box is provided with three ports, two of which are connected to a connecting wire, and the other end of the two connecting wires is fixedly connected to the inside of the horizontal plate.

[0013] By adopting the above technical solution and setting up ports and connecting lines, the electrical control box can serve as the core of the equipment's electrical control. The ports are connected to the horizontal plate via connecting lines. This plug-in design makes circuit connection and subsequent maintenance more convenient, achieving the effect of powering LED light panels and transmitting detection signals.

[0014] Preferably, the cable management mechanism includes a mounting plate fixedly connected to the side of the beam frame, two connecting plates fixedly connected to the side of the mounting plate, a plurality of springs fixedly connected to the surface of each of the two connecting plates, clamping plates fixedly connected to the surface of each of the springs, and handles fixedly connected to the side of each of the clamping plates.

[0015] By adopting the above technical solution and setting up a clamping mechanism, the connecting wire can be inserted between several sets of clamping plates. Subsequently, the spring force can be used to drive the clamping plates to clamp the wire. When adjusting the line later, the handle can be pulled to release it. This structure replaces the messy wiring scene, making the internal cables of the equipment neat and orderly, reducing the risk of short circuits and poor contact, reducing the equipment failure and maintenance rate, and achieving the purpose of organizing the line.

[0016] Preferably, four rubber blocks are fixedly connected to the bottom of the support plate.

[0017] By adopting the above technical solution and setting rubber blocks, the bottom of the device is made slip-resistant.

[0018] Preferably, a limiting frame is fixedly installed on the top of the support plate by studs, and an inner frame is provided inside the limiting frame. Four vertical plates are fixedly connected to the bottom of the light shield, and a horizontal plate is fixedly connected to the bottom of the four vertical plates. Several live connector pins are fixedly installed inside the horizontal plate.

[0019] By adopting the above technical solution, and by setting a limiting frame and an inner frame, when changing LED light panels of different sizes, the studs can be loosened, the inner frame can be pulled out, and after replacing it with an inner frame of the appropriate size, it can be fixed again, thus completing the switching of the testing fixture. This achieves the effect of one set of equipment being compatible with the testing of multiple specifications of light panels. By setting a horizontal plate and a live connector pin, after the LED light panel is placed in position, the light shield moves down, and the live connector pin on the horizontal plate automatically contacts the LED light panel electrode to power the LED light panel. After the test is completed, the light shield moves up, and the live connector pin disengages, thus achieving the purpose of testing the brightness of the LED light panel.

[0020] Preferably, a power cord is fixedly installed on the side of the electrical control box, one end of the power cord is fixedly connected to a power connector, and a protective sleeve is fitted over the surface of the power connector.

[0021] By adopting the above technical solution and setting a protective cover, the power head can be wrapped with the protective cover when not in use, thereby preventing dust and moisture from adhering to the surface.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This LED light panel detector, through a monitoring mechanism, allows the LED light panel to be placed in position. An electric push rod extends, causing an acrylic top plate and a light-shielding plate to move downwards. The light-shielding plate covers the LED light panel, which then illuminates. A camera captures an image of the illuminated state, which is then transmitted to a PLC programmable controller. Finally, the PLC analyzes the image based on preset logic and triggers an alarm light and sound when a defect is detected. This structure automates monitoring, replacing manual visual inspection of the light's on / off state, avoiding misjudgments caused by visual fatigue and bright light stimulation, and significantly improving detection accuracy. The light-shielding plate and acrylic top plate work together to shield against external light interference, ensuring clear images captured by the camera. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A detector for an LED light panel, referring to... Figure 1 It includes a support plate 1, a beam frame 2, a monitoring mechanism 3, a cable management mechanism 15, an electrical control box 13, and a horizontal plate 24. The monitoring mechanism 3 includes a support frame 301 fixedly connected to one side of the beam frame 2. A camera 302 is fixedly installed on the side of the support frame 301. A PLC programmable controller 303 and an alarm light 304 are fixedly installed on the other side of the beam frame 2.

[0033] A fixing plate 4 is fixedly connected to the side of the beam frame 2. An electric push rod 5 is fixedly installed inside the fixing plate 4. An acrylic top plate 6 is fixedly connected to the bottom of the electric push rod 5. A light shield 7 overlaps the bottom of the acrylic top plate 6. Four screws 8 are threadedly connected to the inside of the acrylic top plate 6 and the inside of the light shield 7. By setting up a monitoring mechanism 3, after the LED light panel is placed in place, the electric push rod 5 extends, driving the acrylic top plate 6 and the light shield 7 to move down. The light shield 7 covers the LED light panel, and then the LED light panel is powered on and emits light, enabling the camera to record. The camera 302 captures an image of the light's on / off status and transmits it to the PLC programmable controller 303. Finally, the PLC programmable controller 303 analyzes the image according to preset logic and triggers an audible and visual alarm 304 when it determines that the light is not up to standard. This structure achieves the effect of replacing manual visual inspection of the light's on / off status through automated monitoring, avoiding misjudgments caused by visual fatigue and light stimulation, and greatly improving the detection accuracy. The light shield 7 and the acrylic top plate 6 work together to shield against external light interference, ensuring that the image captured by the camera 302 is clear.

[0034] Please see Figure 1 and Figure 5 The top of the support plate 1 is fixedly connected to a beam frame 2. By setting the beam frame 2, a stable and orderly spatial structure can be formed for the entire equipment, avoiding shaking and displacement of various components due to lack of reasonable support, and ensuring the overall stability of the equipment during operation. The top of the support plate 1 is fixedly connected to four guide rails 9. The interior of the light shield 7 has four through holes 21, and each of the four through holes 21 is fixedly connected to a sliding sleeve 22. The sliding sleeve 22 is slidably connected to the surface of the guide rail 9. The top of each of the four guide rails 9 is fixedly connected to a limiting disc 10. By setting the guide rails 9 and the sliding sleeves 22, when the electric push rod 5 moves the light shield 7 downward, the sliding sleeve 22 slides along the guide rail 9, restricting the light shield 7 to only move vertically up and down. The limiting disc 10 is fixed to the top of the guide rail 9 to prevent the light shield 7 from detaching from the guide rail 9. This ensures that the relative positions of the light shield 7, the LED light panel, and the camera 302 are absolutely consistent during each test, avoiding the test error caused by the misalignment of the LED light panel and the offset of the light shield 7.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The surface of the electrical control box 13 has three ports 18. Two ports 18 are each connected to a connecting wire 17. The other ends of the two connecting wires 17 are fixedly connected to the inside of the horizontal plate 24. By setting up the ports 18 and connecting wires 17, the electrical control box 13 can serve as the core of the equipment's electrical control. The ports 18 are connected to the horizontal plate 24 via the connecting wires 17. This plug-in design makes circuit connection and subsequent maintenance more convenient, achieving the effect of powering the LED light panel and transmitting detection signals. The cable management mechanism 15 includes a mounting plate 1501 fixedly connected to the side of the beam frame 2. Two connecting plates 1502 are fixedly connected to the side of the mounting plate 1501. Each connecting plate 1502 has several springs 1503 fixedly connected to its surface, and each spring 1503 has a clamping plate 1504 fixedly connected to its surface. Each clamping plate 1504 has a handle 1505 fixedly connected to its side. By setting up a wire clamping mechanism, the connecting wire 17 can be inserted between several sets of clamping plates 1504. Subsequently, the elastic force of the springs 1503 can be used to drive the clamping plates 1504 to clamp the wire. When adjusting the line later, the handle 1505 can be pulled to release it. This structure replaces the messy wiring scene, makes the internal cables of the equipment neat and orderly, reduces the risk of short circuits and poor contact, reduces the equipment failure and maintenance rate, and achieves the purpose of organizing the line.

[0036] Please see Figure 1 and Figure 4 Four rubber blocks 16 are fixedly connected to the bottom of the support plate 1 to prevent slippage of the bottom of the device. A limit frame 11 is fixedly installed on the top of the support plate 1 by studs. An inner frame 12 is set inside the limit frame 11. Four vertical plates 23 are fixedly connected to the bottom of the light shield 7. A horizontal plate 24 is fixedly connected to the bottom of the four vertical plates 23. Several live connector pins 25 are fixedly installed inside the horizontal plate 24. By setting the limit frame 11 and the inner frame 12, when changing LED light panels of different sizes, the studs can be loosened, the inner frame 12 can be pulled out, and a matching inner frame 12 can be replaced and then fixed again to complete the switching of the testing fixture. This allows one set of equipment to be compatible with multiple types of LED light panels. The effect of testing the LED light panel is achieved by setting up the horizontal plate 24 and the live connector pin 25. After the LED light panel is placed in position, the light shield 7 moves down, and the live connector pin 25 on the horizontal plate 24 automatically contacts the LED light panel electrode to power the LED light panel. After the test is completed, the light shield 7 moves up, and the live connector pin 25 disengages, thus achieving the purpose of testing the brightness of the LED light panel. A power cord 14 is fixedly installed on the side of the electrical control box 13. One end of the power cord 14 is fixedly connected to a power head 19. A protective sleeve 20 is fitted on the surface of the power head 19. By setting the protective sleeve 20, when the power head 19 is not in use, the protective sleeve 20 can cover the plug to prevent dust and moisture from adhering to the surface.

[0037] The implementation principle of this application embodiment is as follows: First, the operator adjusts the specifications of the inner frame 12 of the limiting frame 11 according to the size of the LED light panel to be tested. If the size of the LED light panel does not match the current inner frame 12, loosen the studs and pull out the original inner frame 12. Replace with an inner frame 12 of the appropriate size and then fix the studs again to ensure that the inner frame 12 can accurately limit the position of the LED light panel and complete the preparation for switching the testing fixture. At the same time, check the power cord 14 on the side of the electrical control box 13 to ensure that the protective cover 20 on the surface of the power head 19 has been removed. Insert the power head 19 into the external power supply to power the entire equipment.

[0038] Then, place the LED light panel to be tested in the inner frame 12 of the limiting frame 11, so that its position is precisely limited by the inner frame 12 to avoid misalignment. Next, organize the equipment wiring and insert the connecting wire 17 connected to the port 18 of the electrical control box 13 into the clamping plate 1504 of the cable management mechanism 15. The elastic force of the spring 1503 drives the clamping plate 1504 to clamp the wire. If the wiring needs to be adjusted, pull the handle 1505 to release the clamping plate 1504, ensuring that the cables are neat and orderly and reducing the risk of short circuit.

[0039] Then, the equipment is started, the monitoring mechanism 3 begins to operate, the electric push rod 5 on the side of the beam frame 2 extends, driving the acrylic top plate 6 and the light shield 7 to move down. At this time, the sliding sleeve 22 in the through hole 21 inside the light shield 7 slides along the guide rail 9 at the top of the support plate 1 to ensure that the light shield 7 descends vertically. The limiting disc 10 at the top of the guide rail 9 prevents the light shield 7 from disengaging from the guide rail 9. As the light shield 7 moves down, the horizontal plate 24 at its bottom descends synchronously. The live connector pin 25 inside the horizontal plate 24 contacts the electrode of the LED lamp panel, energizing the lamp panel to make it emit light.

[0040] Afterwards, the light shield 7 completely covers the LED light panel, and the acrylic top plate 6 works with the light shield 7 to block external light interference. The camera 302 on the side of the support frame 301 begins to collect images of the LED light panel's lighting status and transmits the image data to the PLC programmable controller 303. The PLC programmable controller 303 analyzes the image according to the preset qualified standard logic to determine whether the light panel has problems such as not lighting or abnormal brightness.

[0041] Subsequently, if the PLC programmable controller 303 determines that the LED light panel is unqualified, it will immediately trigger the alarm light 304 on the other side of the beam frame 2 to issue an audible and visual alarm, prompting the operator that the LED light panel is a defective product. If it is determined to be qualified, the alarm light 304 will not activate. During the testing process, the rubber block 16 at the bottom of the support plate 1 increases the friction between the equipment and the placement surface to prevent the equipment from shaking and affecting the testing accuracy.

[0042] Finally, after the test is completed, the electric push rod 5 retracts, causing the acrylic top plate 6, the light shield 7, and the horizontal plate 24 to move upward and reset. The live connector pin 25 disengages from the LED lamp panel electrode. The operator takes out the tested LED lamp panel and puts in the next LED lamp panel to be tested, repeating the above process. If the equipment needs to be shut down for a long time, the power head 19 should be unplugged and covered with a protective cover 20 to prevent dust and moisture from adhering and to ensure the service life of the power head 19.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
