LED lamp panel detection machine

Abstract

The application relates to an LED lamp panel detection machine and relates to the technical field of LED lamp panel detection. The machine body is internally provided with a detection table. The upper surface of the detection table is fixedly connected with a bottom plate. The upper surface of the bottom plate is fixedly connected with four stand columns. The lower movement of the pressing plate driven by the air cylinder pushes the carrier plate and the lamp panel in the mold frame to move downward under the limitation of spring elasticity, so that the conductive contact at the bottom of the lamp panel is in contact with the conductive contact head of the power line, and then the lamp panel is automatically powered and lit. The light intensity data of each lamp panel can be automatically collected by arranging the photosensitive module below the detection hole and electrically connecting the photosensitive module with the processing module provided with a display screen. The light intensity data is fed back to the processing module for processing and analysis. Finally, the result is directly displayed on the display screen. The spring can support the mold frame and automatically drive the mold frame to move back with the carrier plate and the lamp panel after detection, so that the detection process is continuous.

Description

Technical Field

[0001] This application relates to the field of LED lamp panel testing technology, and in particular to an LED lamp panel testing machine. Background Technology

[0002] LED light panels are electronic lighting devices that use LEDs as the core light source. They scientifically arrange and combine multiple LED beads for illumination. With advantages such as energy saving, long lifespan, and environmental friendliness, they are widely used in lighting various spaces such as shopping malls, offices, and homes.

[0003] During the production process, the brightness of LED light panels needs to be tested to ensure the pass rate of LED light panels. In order to meet the testing needs of LED light panels on the factory production line, an LED light panel testing machine is proposed here. Summary of the Invention

[0004] The purpose of this application is to provide an LED lamp panel testing machine that can assist manual labor in quickly completing the brightness testing of LED lamp panels, saving manpower and improving testing efficiency.

[0005] This application provides an LED lamp panel testing machine with the following technical solution: An LED lamp panel testing machine includes a machine body, an internal testing platform, a base plate fixedly connected to the upper surface of the testing platform, four columns fixedly connected to the upper surface of the base plate, a mold frame slidably fitted onto the outer circumference of the four columns, a carrier plate placed inside the mold frame, and lamp panels arranged at equal intervals inside the carrier plate. Equally spaced testing holes are opened inside the mold frame, the positions of the lamp panels corresponding to the positions of the testing holes. Four springs are provided between the base plate and the mold frame, each spring being sleeved on the outside of the columns. The upper surface of the base plate is provided with... The device comprises equidistantly arranged bases, each with two power cords fixedly connected inside. Each power cord has a conductive contact fixedly connected to its top end. Each lamp panel has two conductive contacts on its bottom surface, the positions of which correspond to the positions of the conductive contacts. The upper surface of the base plate is provided with equidistantly arranged photosensitive modules, each located directly below a detection hole. A processing module is located at the top of the device, with a display screen mounted on its front. The photosensitive modules are electrically connected to the processing module. A cylinder is fixedly connected inside the device, with a pressure plate fixedly connected to its output end, located directly above the mold frame.

[0006] By adopting the above technical solution, the cylinder drives the pressure plate to move downward. The pressure plate pushes the carrier plate and lamp disk inside the mold frame downward under the constraint of the spring force, so that the conductive contacts at the bottom of the lamp disk contact the conductive contacts of the power cord, thereby automatically turning on the power and lighting up the lamp disk. By setting a photosensitive module below the detection hole and electrically connecting the photosensitive module to the processing module with a display screen, the brightness data of each lamp disk can be automatically collected and fed back to the processing module for processing and analysis. Finally, the results are displayed intuitively on the display screen. The spring can support the mold frame and can also automatically drive the mold frame to move the carrier plate and lamp disk back after the test is completed, making the test process continuous. This assists manual labor in quickly completing the brightness test of LED lamp disks, saving manpower and improving test efficiency.

[0007] Preferably, the bottom surface of the mold frame is fixedly connected with equidistantly arranged light shields, which are respectively located at the edge position directly below the detection hole.

[0008] By adopting the above technical solution, the setting of the light shield can effectively block the light emitted by adjacent light panels, avoid mutual interference between the light sources of the light panels, and ensure that during the detection process, each photosensitive module can only receive the light emitted by the light panel in the corresponding detection hole, thereby ensuring the accuracy of the detection results and enabling the brightness data to truly reflect the actual brightness of each light panel.

[0009] Preferably, each of the columns is fixedly connected to an installation rod on its upper surface, and the outer circumferential surface of the installation rod is threaded with a limit ring.

[0010] By adopting the above technical solution, when the mold frame needs maintenance, replacement or repair, it can be removed from the mounting rod simply by rotating and removing the limit ring, making it easy to disassemble the mold frame from the column, thus improving the maintainability and flexibility of the equipment.

[0011] Preferably, the diameter of the mounting rod is smaller than the diameter of the column, and a rubber ring is fixedly connected to the bottom surface of the limiting ring.

[0012] By adopting the above technical solution, the diameter of the mounting rod is smaller than the diameter of the column, and a rubber ring is provided on the bottom surface of the limiting ring, which can limit the limiting ring to the upper surface of the column. It can also tighten the bottom of the limiting ring to the upper surface of the column through the rubber ring, increase the friction between the limiting ring and the column, prevent the limiting ring from easily loosening, and improve the stability of the limiting ring. The rubber ring can also effectively reduce the collision between the mold frame and the limiting ring when the mold frame moves back, and protect the contact position between the limiting ring and the mold frame.

[0013] Preferably, the conductive contact has a U-shaped structure and a certain degree of elasticity.

[0014] By adopting the above technical solution, when the conductive contact comes into contact with the conductive contact on the bottom surface of the lamp panel, the U-shaped conductive contact with a certain degree of elasticity can provide a certain fault tolerance space, so that the conductive contact can maintain good contact with the conductive contact through its own elastic deformation, avoiding damage to both, and improving the reliability and stability of the equipment operation.

[0015] Preferably, a cable groove is provided on the back of the machine body, and the bottom of each power cord passes through the base plate and the machine body and extends into the inside of the cable groove, and the power cord is connected to an external power source.

[0016] By adopting the above technical solution, the cable trays help to organize and protect the power cords, preventing them from becoming tangled and messy. The power cords are connected to an external power source to provide power for the lighting of the lamp panel.

[0017] Preferably, a rubber pad is fixedly connected to the bottom surface of the pressure plate.

[0018] By adopting the above technical solution, when the cylinder drives the pressure plate to move down and contact the carrier plate and lamp disk, the rubber pad can play a buffering role, preventing the pressure plate from directly contacting the carrier plate and lamp disk and generating a large impact force, thus avoiding damage to the carrier plate, lamp disk and pressure plate.

[0019] Preferably, the mold frame has a placement groove inside, and the outer surface of the carrier plate is slidably connected to the inner wall of the placement groove.

[0020] By adopting the above technical solution, the placement slot not only facilitates the placement and removal of the carrier plate and lamp panel, but also provides a certain limiting effect on the carrier plate and lamp panel, thereby improving the stability of the carrier plate and lamp panel during the inspection process.

[0021] Preferably, the display screen shows squares that are equidistant from the positions of the photosensitive modules, and numbers corresponding to the positions of the photosensitive modules are displayed inside the squares. The squares are also marked with yellow for unqualified and green for qualified.

[0022] By adopting the above technical solution, according to the pre-set program, when the brightness data of the corresponding lamp panel fed back by the photosensitive module reaches the qualified standard, the corresponding box will change from yellow to green, indicating that the brightness of the lamp panel at the corresponding position is qualified. When the brightness data of the corresponding lamp panel fed back by the photosensitive module does not reach the qualified standard, the corresponding box will always be displayed as yellow, indicating that the brightness of the lamp panel at the corresponding position is unqualified.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This LED lamp panel testing machine uses a cylinder to drive a pressure plate downwards. The pressure plate pushes a carrier plate and lamp panel inside the mold frame downwards under the constraint of spring force, causing the conductive contacts at the bottom of the lamp panel to contact the conductive contacts of the power cord, thus automatically energizing and illuminating the lamp panel. A photosensitive module is installed below the detection hole and electrically connected to a processing module equipped with a display screen. This allows for the automatic collection of brightness data from each lamp panel, which is then fed back to the processing module for analysis. The results are then displayed intuitively on the screen. The springs support the mold frame and also... After testing, the machine can automatically drive the mold frame to move the carrier plate and lamp panel back, ensuring a smooth testing process. Limiting grooves on the mold frame facilitate the placement and removal of the carrier plate and lamp panel. A light shield at the bottom edge of the testing hole prevents interference between light sources in the lamp panels, ensuring accurate test results. A mounting rod and a limiting ring threaded to the mounting rod facilitate subsequent disassembly and maintenance of the mold frame. Overall, the testing machine assists manual labor in quickly completing the brightness testing of LED lamp panels on the production line, saving manpower, improving testing efficiency, and ensuring accurate test results.

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.

[0037] Example 1: An LED lamp panel testing machine, referring to... Figure 1 , Figure 4 and Figure 5 The device includes a body 1, inside which is a testing platform 2. A base plate 3 is fixedly connected to the upper surface of the testing platform 2. Four columns 4 are fixedly connected to the upper surface of the base plate 3. A mold frame 5 is slidably fitted onto the outer circumference of the four columns 4. A carrier plate 6 is placed inside the mold frame 5. Light plates 7 are arranged at equal intervals inside the carrier plate 6. Detection holes 8 are arranged at equal intervals inside the mold frame 5. The positions of the light plates 7 correspond to the positions of the detection holes 8. Four springs 9 are provided between the base plate 3 and the mold frame 5. The springs 9 are respectively fitted onto the outside of the columns 4.

[0038] Reference Figure 5 , Figure 8 and Figure 9 The upper surface of the base plate 3 is provided with equidistantly arranged bases 10. Each base 10 is fixedly connected to two power lines 11. Each power line 11 is fixedly connected to a conductive contact 12 at its top. Each lamp panel 7 is provided with two conductive contacts 13 on its bottom surface. The positions of the conductive contacts 13 correspond to the positions of the conductive contacts 12.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The upper surface of the base plate 3 is provided with photosensitive modules 14 arranged at equal intervals. The photosensitive modules 14 are located directly below the detection holes 8. The top of the machine body 1 is provided with a processing module 15. The front of the processing module 15 is equipped with a display screen 16. The photosensitive modules 14 and the processing module 15 are electrically connected. A cylinder 22 is fixedly connected inside the machine body 1. A pressure plate 23 is fixedly connected to the output end of the cylinder 22. The pressure plate 23 is located directly above the mold frame 5.

[0040] The display screen 16 shows squares that are equidistant from the positions of the photosensitive modules 14. Each square contains a number corresponding to the position of the photosensitive modules 14. The squares are either yellow (indicating failure) or green (indicating success). According to a pre-set program, when the brightness data of the corresponding lamp panel 7 fed back by the photosensitive modules 14 meets the passing standard, the corresponding square will change from yellow to green, indicating that the brightness of the lamp panel 7 at the corresponding position is qualified. When the brightness data of the corresponding lamp panel 7 fed back by the photosensitive modules 14 does not meet the passing standard, the corresponding square will always be displayed as yellow, indicating that the brightness of the lamp panel 7 at the corresponding position is unqualified.

[0041] Reference Figure 7 and Figure 8 The conductive contact 12 has a U-shaped structure and a certain degree of elasticity. When the conductive contact 12 contacts the conductive contact 13 on the bottom surface of the lamp panel 7, the U-shaped structure and the certain elasticity of the conductive contact 12 can provide a certain fault tolerance space, so that the conductive contact 12 can maintain good contact with the conductive contact 13 through its own elastic deformation, avoid damage to both, and improve the reliability and stability of the equipment operation.

[0042] Reference Figure 1 , Figure 8 and Figure 9 The back of the body 1 is provided with a wire groove 21. The bottom of each power cord 11 passes through the base plate 3 and the body 1 and extends into the inside of the wire groove 21. The power cord 11 is connected to an external power source. The wire groove 21 serves to organize and protect the power cord 11. The power cord 11 is connected to an external power source to provide power support for lighting the lamp panel 7.

[0043] Reference Figure 2 and Figure 3 A rubber pad 24 is fixedly connected to the bottom surface of the pressure plate 23. When the cylinder 22 drives the pressure plate 23 to move down and contact the carrier plate 6 and the lamp plate 7, the rubber pad 24 can play a buffering role to prevent the pressure plate 23 from directly contacting the carrier plate 6 and the lamp plate 7 and generating a large impact force, thus avoiding damage to the carrier plate 6, the lamp plate 7 and the pressure plate 23.

[0044] Reference Figure 4 and Figure 5 The mold frame 5 has a placement groove 25 inside. The outer surface of the carrier plate 6 is slidably connected to the inner wall of the placement groove 25. The placement groove 25 not only facilitates the placement and removal of the carrier plate 6 and the lamp plate 7, but also plays a certain role in limiting the carrier plate 6 and the lamp plate 7, thereby improving the stability of the carrier plate 6 and the lamp plate 7 during the detection process.

[0045] Example 2: An LED lamp panel testing machine, referring to... Figure 4 , Figure 5 and Figure 6The bottom surface of the mold frame 5 is fixedly connected with light shields 17 arranged at equal intervals. The light shields 17 are respectively set at the edge position directly below the detection hole 8. The setting of the light shields 17 can effectively block the light emitted by adjacent lamp disks 7, avoid mutual interference between the light sources of the lamp disks 7, so that during the detection process, each photosensitive module 14 can only receive the light emitted by the lamp disk 7 in the corresponding detection hole 8, thereby ensuring the accuracy of the detection results and making the brightness data truly reflect the actual brightness of each lamp disk 7.

[0046] Reference Figure 4 and Figure 5 Each column 4 has a mounting rod 18 fixedly connected to its upper surface. The outer circumferential surface of the mounting rod 18 is threaded with a limit ring 19. When the mold frame 5 needs to be maintained, replaced or repaired, the limit ring 19 can be rotated and removed from the mounting rod 18, making it easy to remove the mold frame 5 from the column 4, thus improving the maintainability and flexibility of the equipment.

[0047] Reference Figure 4 and Figure 5 The diameter of the mounting rod 18 is smaller than the diameter of the column 4. A rubber ring 20 is fixedly connected to the bottom surface of the limiting ring 19. The mounting rod 18 has a smaller diameter than the column 4, and the bottom surface of the limiting ring 19 is provided with a rubber ring 20. This can limit the limiting ring 19 to the upper surface of the column 4, and also allow the bottom of the limiting ring 19 to be tightened to the upper surface of the column 4 through the rubber ring 20. This increases the friction between the limiting ring 19 and the column 4, prevents the limiting ring 19 from easily loosening, and improves the stability of the limiting ring 19. The setting of the rubber ring 20 can also effectively reduce the collision between the mold frame 5 and the limiting ring 19 when the mold frame 5 moves back, and protect the contact position between the limiting ring 19 and the mold frame 5.

[0048] The implementation principle of this application embodiment is as follows: When performing brightness detection of LED lamp panel 7, the carrier plate 6 with lamp panel 7 is placed in the placement slot 25 inside the mold frame 5, with the lamp beads and conductive contacts 13 of lamp panel 7 facing downwards. The cylinder 22 is activated to push the pressure plate 23 downwards. The pressure plate 23 pushes the carrier plate 6 and lamp panel 7 inside the mold frame 5 downwards, and at the same time, the spring 9 is compressed. As the lamp panel 7 moves downwards, the conductive contacts 13 on the bottom surface of the lamp panel 7 contact the conductive contacts 12 at the top of the power line 11 inside the base 10, thereby automatically powering on and lighting up the lamp panel 7. The light emitted after the lamp panel 7 is lit passes through the photosensitive module 14 below the detection hole 8. The photosensitive module 14 automatically collects the brightness data of each lamp panel 7 and feeds the brightness data back to the processing module 15. The processing module 15 processes and analyzes the received brightness data through the processing unit, and finally displays the results intuitively on the display screen 16. According to the preset program, when the brightness data of the corresponding lamp panel 7 fed back by the photosensitive module 14 reaches the qualified standard, the corresponding... The box will change from yellow to green, indicating that the brightness of the corresponding lamp panel 7 is qualified. When the brightness data of the corresponding lamp panel 7 fed back by the photosensitive module 14 does not meet the qualified standard, the corresponding box will always be displayed as yellow, indicating that the brightness of the corresponding lamp panel 7 is unqualified. The staff can quickly obtain the test results by observing the color change of the box on the display screen 16. The qualified lamp panel 7 flows to the next process, and the unqualified lamp panel 7 is returned to the manual test to check the power supply of each lamp bead on the lamp panel 7. During the test, the light shield 17 can effectively block the light emitted by adjacent lamp panels 7, avoid mutual interference between the light sources of the lamp panels 7, and ensure the accuracy of the test results. After the test is completed, the cylinder 22 drives the pressure plate 23 to move back, the compressed spring 9 restores its deformation, and automatically drives the mold frame 5 to move the carrier plate 6 and lamp panel 7 back, so that the mold frame 5 returns to the initial position. At this time, the staff takes out the tested carrier plate 6 and lamp panel 7, puts the new carrier plate 6 and lamp panel 7 into the mold frame 5, and performs the next round of testing.

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.
