The image acquisition device is placed on the base and faces the test position. The stop slides on the base and is adapted to switch between a closed state and an open state. The metal pin is connected to the stop. When the stop is in the closed state, it covers the placement opening, and the metal pin is close to the test position.
[0004] While the above technology can determine whether the LED integrated board under test is lit and form a closed space for the test by using a baffle to prevent the UV light emitted by the lit LED integrated board from hurting people's eyes, it lacks reliable limiting after the LED is placed in the test position, which is prone to positional deviation, resulting in misalignment between the metal pin and the pin, causing poor power supply and misjudgment of the test.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] The embodiments of this utility model will be described below based on its overall structure.
[0025] In this embodiment, please refer to Figure 1 - Figure 6 As shown, an LED light illumination detection device includes a detection box 1. A control module 101 is installed at the bottom of the detection box 1. The control module 101 provides the electrical energy required for detection and controls the operation of the entire device. A detection cavity 102 is provided on the detection box 1, which provides a closed detection space for LED light detection, avoiding external interference and UV light injury. Support plates 201 are symmetrically fixed inside the detection cavity 102. A placement plate 2 is fixed between the tops of the two support plates 201. A placement groove 203 is provided on the upper surface of the placement plate 2 for preliminary positioning of the LED light integrated board. Several grooves are provided on the lower surface of the placement plate 2. A pin hole (not shown in the figure) is provided, communicating with the placement slot 203. The position and number of the pin holes correspond one-to-one with the pin position and number of the LED integrated board to be tested, ensuring that the metal pins 302 can accurately pass through and contact the pins. A parallel pin disk 3 is provided below the placement plate 2. Several metal pins 302 are mounted on the pin disk 3. The metal pins 302 are all floatingly connected to the lower surface of the pin disk 3. Specifically, the floating connection is as follows: a fixing plate 3021 is fixedly sleeved on the bottom outer wall of each metal pin 302. Support springs 3022 are fixed on both sides of the upper surface of each fixing plate 3021. Each support spring 3022... The top of each of the 22 pins is fixedly connected to the lower surface of the needle plate 3. The support spring 3022 is always in a pre-compressed state, providing upward elastic support for the metal pins 302. The bottom ends of several metal pins 302 are electrically connected to the control module 101 via wires. The control module 101 transmits the electrical energy required for detection to the metal pins 302 via wires. A baffle 103 is installed on the outer wall of the detection box 1 at the detection cavity 102 via screws. A closing plate 104 is slidably installed on the baffle 103. The closing plate 104 is used to cover the opening of the detection cavity 102, thereby sealing the detection space. The side wall of the needle plate 3 and the bottom of the outer wall of the closing plate 104 are connected by an L-shaped connecting plate 3. The L-shaped connecting plate 303 is connected to the needle plate 3. One end of the L-shaped connecting plate 303 is welded and fixed to the side wall of the needle plate 3, and the other end is fixed to the outer wall of the closing plate 104 by screws. This ensures that the closing plate 104 can drive the needle plate 3 to rise and fall synchronously when it slides. Both support plates 201 are provided with guide grooves 2011. Both outer walls of the needle plate 3 are fixed with guide plates 301. Both guide plates 301 pass through the corresponding guide grooves 2011 and are in sliding contact. The guide plates 301 cooperate with the guide grooves 2011 to provide guidance and limit for the rise and fall of the needle plate 3, and prevent the needle plate 3 from deviating during the rise and fall process. One side of the upper surface of both guide plates 301 is fixed with a vertical toothed plate 3011.
[0026] Both support plates 201 have a limiting component 4 on their outer top. The limiting component 4 is used to limit and fix the LED integrated board in the placement slot 203 when the needle plate 3 moves upward. Both limiting components 4 include a U-shaped frame 401 fixed to the top of the outer wall of the support plate 201 with screws. The U-shaped frame 401 is horizontally set and its opening faces the support plate 201. A shaft 402 is rotatably installed on the frame wall of the U-shaped frame 401 away from the support plate 201. A lead screw 403 is fixed to the end of the shaft 402. The end of the lead screw 403 is rotatably connected to the outer wall of the support plate 201. A movable plate 404 is movably sleeved on the outer wall of the lead screw 403. A horizontal limiting plate 405 is fixed to the top of the movable plate 404. Both the support plate 201 and the placement plate 2 have matching square through holes 202. The limiting plate 405 passes through the square through holes 202. 2 is located inside the placement slot 203. The outer wall of the shaft 402 is fixedly fitted with a gear 4021. Two vertical toothed plates 3011 are matched with the corresponding gears 4021. After meshing, power transmission is realized. The inner top wall of the detection cavity 102 is equipped with an image acquisition camera 5 by screws. The image acquisition camera 5 faces the placement slot 203 of the placement plate 2 and is used to capture the lighting status of the LED light integrated board to be tested and transmit it to the external terminal for judgment. An iron block 1041 is embedded in the center of the top of the closing plate 104. A magnet 105 is fixed on the outer wall of the detection box 1 above the detection cavity 102. The magnet 105 is magnetically connected to the iron block 1041 and is used to lock and fix the closing plate 104 after it is closed. A pull plate 1042 is fixed on the top of the outer wall of the closing plate 104. The pull plate 1042 is easy for the operator to pull.
[0027] When testing the LED integrated board, the operator places the LED integrated board to be tested into the placement slot 203, ensuring that its pins are aligned with the pin holes on the lower surface of the placement plate 2. After placement, the operator pulls the closing plate 104 upward using the pull plate 1042. The closing plate 104 slides upward, driving the pin disk 3 to move upward synchronously through the L-shaped connecting plate 303. As the pin disk 3 moves, the guide plates 301 on both sides slide upward along the guide grooves 2011 of the support plate 201, achieving guide and limit. At the same time, the vertical toothed plates 3011 on the guide plates 301 move synchronously. Because the vertical toothed plates 3011 are matched with the gears 4021 in the limiting component 4... When the vertical toothed plate 3011 moves to a certain position, it will mesh with the gear 4021. As it continues to move upward, it drives the gear 4021 to rotate. The gear 4021 drives the shaft 402 to rotate, and the shaft 402 drives the lead screw 403 to rotate. When the lead screw 403 rotates, it drives the moving plate 404 to move away from the support plate 201 through the threaded transmission. The moving plate 404 drives the limiting plate 405 to move synchronously, so that the end of the limiting plate 405 moves into the placement groove 203. At this time, the end of the limiting plate 405 is tightly attached to the side wall of the LED lamp integrated board, so as to limit and fix the LED lamp integrated board and avoid vertical displacement during the detection process.
[0028] As the needle plate 3 continues to move upward, the tip of the metal pin 302 will contact the pins of the LED integrated board. As the needle plate 3 continues to move upward, because the tip of the metal pin 302 is in contact with the pins, the needle plate 3 will stretch the support spring 3022 along the metal pin 302, ensuring that the metal pin 302 always maintains stable contact with the pins, while avoiding rigid compression that could deform or damage the pins. When the closing plate 104 moves to the top, the embedded iron block 1041 magnetically attracts the magnet 105 on the outer wall of the detection box 1, fixing the closing plate 104. At this time, the detection cavity 102 forms a closed space. The control module 101 supplies power to the metal pin 302 through wires, and electrical energy is transmitted through the metal pin 302. The image is fed to the LED integrated board, which lights up the LED integrated board. The image acquisition camera 5 inside the detection cavity 102 captures the lighting status of the LED integrated board in real time and transmits the captured image to the external terminal. The operator judges the lighting status of the LED integrated board through the image and completes the detection. After the detection is completed, the operator pulls down the pull plate 1042, the closing plate 104 drives the needle plate 3 to move down, the metal pin 302 separates from the pin, and at the same time the vertical toothed plate 3011 moves down with the guide plate 301, driving the gear 4021 to rotate in the opposite direction, so that the limiting plate 405 exits from the placement slot 203, releasing the limitation on the LED integrated board. The operator can then take out the tested LED integrated board.
[0029] This automatically completes the limiting and fixing of the LED light integrated board, effectively avoiding the problem of poor contact of the ejector pins caused by positional deviation during the detection process. Furthermore, the floating metal ejector pins 302 can achieve adaptive adjustment of contact pressure, which can ensure stable contact with the pins and avoid damage to the pins caused by rigid contact, thus eliminating pin wear and poor power supply problems.
[0030] The working principle of this utility model is as follows:
[0031] When testing the LED integrated circuit board, the operator places the LED integrated circuit board to be tested into the placement slot 203, ensuring that its pins are aligned with the pin holes on the lower surface of the placement plate 2. After placement, the operator pulls the closing plate 104 upward using the pull plate 1042. The closing plate 104 slides upward, driving the pin disk 3 to move upward synchronously through the L-shaped connecting plate 303. As the pin disk 3 moves, the guide plates 301 on both sides slide upward along the guide grooves 2011 of the support plate 201, achieving guide and limit. At the same time, the vertical toothed plates 3011 on the guide plates 301 move synchronously. 1. Matches with gear 4021 in limiting component 4. When the vertical toothed plate 3011 moves to a certain position, it will mesh with gear 4021. As it continues to move upward, it drives gear 4021 to rotate. Gear 4021 drives shaft 402 to rotate. Shaft 402 drives lead screw 403 to rotate. When lead screw 403 rotates, it drives moving plate 404 to move away from support plate 201 through thread transmission. Moving plate 404 drives limiting plate 405 to move synchronously, so that the end of limiting plate 405 moves into placement groove 203. At this time, the end of limiting plate 405 is tightly attached to the side wall of LED light integrated board.
[0032] As the needle plate 3 continues to move upward, the top of the metal pin 302 will contact the pin of the LED lamp integrated board. As the needle plate 3 continues to move upward, since the top of the metal pin 302 has contacted the pin, the needle plate 3 will stretch the support spring 3022 along the metal pin 302 to ensure that the metal pin 302 always maintains stable contact with the pin. When the closing plate 104 moves to the top, the embedded iron block 1041 and the magnet 105 on the outer wall of the detection box 1 are magnetically attracted to fix the closing plate 104. At this time, the detection cavity 102 forms a closed space. The control module 101 supplies power to the metal pin 302 through the wire. The electrical energy is transmitted to the LED lamp integrated board through the metal pin 302, so that the LED lamp integrated board is lit.
[0033] The image acquisition camera 5 inside the detection cavity 102 captures the lighting status of the LED integrated board in real time and transmits the captured image to an external terminal. The operator judges the lighting status of the LED integrated board through the image and completes the detection. After the detection is completed, the operator pulls down the pull plate 1042, the closing plate 104 moves the needle plate 3 down, the metal pin 302 separates from the pin, and at the same time the vertical toothed plate 3011 moves down with the guide plate 301, driving the gear 4021 to rotate in the opposite direction, so that the limiting plate 405 exits from the placement slot 203, releasing the limitation on the LED integrated board, and the operator can take out the tested LED integrated board.
