Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to a signal detection device for cascaded LED light boards. Background Technology

[0002] A cascaded signal detection device is a technical device that uses a multi-stage modular structure to transmit, amplify, or convert weak target signals step by step, ultimately achieving accurate detection of low-concentration, low-intensity signals. Its core design concept is to solve the problem of insufficient sensitivity of single-stage detection. When the intensity of the target signal (such as trace biomolecules, weak electromagnetic signals, trace pollutant signals, etc.) is too low to be directly identified by conventional single-stage detectors, the signal is amplified to the detectable range through cascading, while suppressing noise interference, thereby improving the accuracy and sensitivity of detection.

[0003] The cascaded signal detection device for LED light boards is a specially designed device used to monitor and analyze the signal integrity, electrical parameters and operating status of LED light boards in real time when they are cascaded (i.e., multiple LED light boards are connected in series or parallel through signal lines). Its core function is to solve common problems in LED cascaded systems such as signal attenuation, timing deviation, short circuit and open circuit, so as to ensure the stability and reliability of large-scale LED display or lighting systems.

[0004] Due to structural limitations, LED strips or light boards may be designed in a cascaded manner (cascaded design: when installing LED strips or light boards, the signal and power supply of the next LED strip or light board are provided by the output of the previous LED strip or light board). Currently, when producing light boards individually, an external LED strip or light board needs to be connected in series to illuminate the LEDs in order to identify whether the LED strip or light board is good or bad (in the current LED strip or light board production process, the SMT equipment is designed in series, and there is no space on the production line to place the LED strip or light board). Therefore, it is impossible to identify whether the output signal of the LED strip is correct during the production of light boards. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a signal detection device for cascaded LED light boards to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a signal detection device for cascaded LED light boards, comprising a support frame, electric push rods installed at both ends of the support frame, and a positioning plate installed at the output end of the electric push rods, an acrylic material at the bottom of the positioning plate, the acrylic material being located on the inner wall of the support frame, test probes being movably sleeved at both ends of the acrylic material, and limit blocks being provided at the bottom of the test probes, a cascaded small board being provided at the top of the support frame, and LED lights being provided on the outer wall of the cascaded small board.

[0007] By adopting the above technical solution, and through the setting of test probes and cascaded small boards, when the light board is produced alone, it is not necessary to connect an external light strip or light board in series to identify the quality of the light strip or light board. The light board is tested by the testing equipment. When the light board is lit, a camera above the machine takes a picture through a transparent acrylic plate for comparison. After the camera takes a picture, it is compared with the OK lighting template by the machine software to check whether the lights on the light board and the testing device are lit. If any light strip or the testing device is not lit, it means that the corresponding light strip is abnormal, and the machine judges it as NG, which improves the working efficiency and practicality of the device. By setting the limit block, the limit block is installed on the top of the support frame, and multiple sets of test probes are installed on the top of the limit block. The outer wall of the test probe is covered with acrylic, so that the acrylic limits the position of the test probe, improving the stability of the test probe during testing.

[0008] The present invention is further configured such that the positioning plate is U-shaped, and both ends of the acrylic are located inside the positioning plate.

[0009] Preferably, the position of the acrylic is limited by setting the shape of the positioning plate, which effectively improves the stability of the acrylic.

[0010] The present invention is further configured such that the electric push rod is bolted to the outer wall of the support frame, and the two sets of electric push rods are arranged opposite to each other.

[0011] Preferably, by having two sets of electric push rods arranged opposite each other, and the support frame and electric push rods bolted together, the stability of the electric push rods at the top of the support frame is effectively improved, making it easier to inspect the light panel on the acrylic.

[0012] The present invention is further configured such that the limiting block is located at the top of the support frame and at the bottom of the acrylic.

[0013] Preferably, by setting a limiting block, multiple sets of test probes are installed on the top of the limiting block, so that the acrylic limits the position of the test probes and improves the stability of the test probes during detection.

[0014] The present invention is further configured such that the acrylic is made of transparent material, and test probes are movably sleeved at both ends of the acrylic, and the two sets of test probes are arranged opposite to each other.

[0015] Preferably, the test probe is designed and mounted on a transparent acrylic plate, aligned with the test point position of the lamp board, so that the cascaded small board, the lamp board and the driver board form an electrical connection.

[0016] The present invention is further configured such that the cascaded small plate is connected to the top of the support frame, and the outer wall of the cascaded small plate is provided with multiple sets of LED lights.

[0017] Preferably, the process facilitates the transfer of testing materials and allows for easy observation by staff.

[0018] The present invention is further configured such that the LED lights are located on top of the cascaded small boards in an equal arrangement, and the cascaded small boards are electrically connected to the light board.

[0019] As a preferred embodiment, this effectively improves the working efficiency and practicality of the device, and enhances detection efficiency.

[0020] The present invention is further configured such that the positioning plate clamps the acrylic, and the positioning plate and the test probe are arranged opposite to each other.

[0021] Preferably, this facilitates the testing of the light panel, improving work efficiency and stability during the testing process.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, through the setting of test probes and cascaded small boards, eliminates the need for an external light strip or light board to be connected in series for identifying the quality of the light strip or light board during the production of the light board alone. The light board is tested by a testing device. When the light board is lit, a camera above the machine takes a picture through a transparent acrylic plate for comparison. After the camera takes a picture, it is compared with the OK lighting template by the machine software to detect whether the lights on the light board and the testing device are lit. If any light strip or the testing device is not lit, it indicates that the corresponding light strip is abnormal, and the machine judges it as NG, thus improving the working efficiency and practicality of the device.

[0024] 2. This utility model uses a limiting block to limit the position of the test probe. The limiting block is installed on the top of the support frame, and multiple test probes are installed on the top of the limiting block. The outer wall of the test probe is covered with acrylic, which limits the position of the test probe and improves the stability of the test probe during detection. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Please refer to the following: A signal detection device for cascaded LED light boards. Figures 1-5 The system includes a support frame 1, with electric push rods 2 installed at both ends. A positioning plate 3 is installed at the output end of each electric push rod 2. An acrylic 5 is located at the bottom of the positioning plate 3, situated on the inner wall of the support frame 1. Test probes 4 are movably mounted at both ends of the acrylic 5, and limit blocks 8 are installed at the bottom of each test probe 4. A cascaded small plate 6 is installed at the top of the support frame 1, and LED lights 7 are installed on the outer wall of the cascaded small plate 6. Through the setup of the test probes 4 and the cascaded small plate 6, when the light panel is produced independently, it is not necessary to connect an external light strip or light panel for series lighting to identify the quality of the light strip or light panel. The light panel can be tested using testing equipment. The detection process involves taking a picture of the light panel when it is lit, through a transparent acrylic plate 5, and comparing it with the image taken by a camera above the machine. After taking the picture, the machine software compares it with the OK light template to check whether the lights on the light panel and the detection device are lit. If any light strip or the detection device is not lit, it indicates that the corresponding light strip is abnormal, and the machine judges it as NG, thus improving the working efficiency and practicality of the device. Through the setting of the limit block 8, which is installed on the top of the support frame 1, and multiple sets of test probes 4 are installed on the top of the limit block 8, and the outer wall of the test probe 4 is covered with acrylic 5, so that the acrylic 5 limits the position of the test probe 4, improving the stability of the test probe 4 during detection.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The positioning plate 3 is U-shaped, and both ends of the acrylic 5 are located inside the positioning plate 3. The position of the acrylic 5 is limited by the shape of the positioning plate 3, which effectively improves the stability of the acrylic 5.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5The electric push rod 2 is bolted to the outer wall of the support frame 1, and the two sets of electric push rods 2 are arranged opposite each other. By arranging the two sets of electric push rods 2 opposite each other and bolting the support frame 1 and the electric push rods 2, the stability of the electric push rod 2 at the top of the support frame 1 is effectively improved, which facilitates the inspection of the light panel on the acrylic 5.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The limiting block 8 is located at the top of the support frame 1 and at the bottom of the acrylic 5. By setting the limiting block 8, multiple sets of test probes 4 are installed on the top of the limiting block 8, so that the acrylic 5 limits the position of the test probes 4 and improves the stability of the test probes 4 during detection.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 Acrylic 5 is made of transparent material, and test probes 4 are movably mounted on both ends of acrylic 5. The two sets of test probes 4 are arranged opposite each other. By designing the test probes 4 to be mounted on the transparent acrylic plate 5 and aligned with the test point position of the lamp board, an electrical connection is formed between the cascaded small board 6, the lamp board, and the driver board.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The cascaded small plate 6 is connected to the top of the support frame 1, and the outer wall of the cascaded small plate 6 is equipped with multiple sets of LED lights 7, which facilitates the transfer of inspection and handover and makes it easier for staff to observe.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The LED lights 7 are positioned in a symmetrical arrangement on top of the cascaded small board 6, and the cascaded small board 6 is electrically connected to the light board, which effectively improves the working efficiency and practicality of the device and increases the detection efficiency.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The positioning plate 3 clamps the acrylic 5, and the positioning plate 3 and the test probe 4 are set opposite to each other, which facilitates the detection of the light board and improves the work efficiency and stability during the detection process.

[0042] In practical operation, this utility model is as follows:

[0043] Appendix Figure 5 This refers to the pin definitions of the LED strip or LED board connector. Pins 1, 2, and 9 are the positive terminals for LED power supply; pins 3, 4, and 8 are the negative terminals for LED power supply and IC power supply; pin 6 is the positive terminal for driver IC power supply; pin 5 is the LED strip signal input pin; and pin 7 is the LED strip signal output pin. When there is no signal output from pin 7 of the LED strip, it will not affect the LED strip's illumination, but it will affect the next LED board connected in series with this LED strip. If the previous LED board has no signal output, the next LED strip will not light up.

[0044] The output signal of the lamp board is integrated into the detection device through circuit design. The device is used in the automatic detection device of the machine on the SMD lamp detection equipment, which contains the signal detection lamp of the corresponding lamp strip. The test probe 4 is designed and mounted on the transparent acrylic plate 5, aligned with the test point position of the lamp board, so that the cascaded small board 6 and the lamp board and the driver board form an electrical connection.

[0045] When the light panel is lit, a camera above the machine takes a picture through the transparent acrylic plate 5 for comparison. After the camera takes the picture, it compares it with the OK light template through the machine software to check whether the lights on the light panel and the detection device are lit. If any light strip is off or the detection device is off, it means that the corresponding light strip is abnormal, and the machine judges it as NG.
