[0014] The beneficial effects of this invention are: 1. The present invention comprises a base platform, a limiting component, a top plate, a driving device, a disc, a detection plate, a honeycomb copper sheet, a bent plate, a slip ring, and a round rod in conjunction with an I-shaped tube, which causes the disc to drive the detection plate downward. Multiple honeycomb holes of the honeycomb copper sheet are inserted into the gaps of the LED display board lamp beads. One conductive copper sheet is connected to the positive terminal of the power supply, and another conductive copper sheet is connected to the negative terminal of the power supply. After the detection plate moves into position, one conductive copper sheet contacts the negative terminal of the lamp bead pin, and another conductive copper sheet contacts the positive terminal of the lamp bead pin. Due to the large arc area of ​​the conductive copper sheet, it can complete the detection when the pin deviates slightly compared to the probe. At the same time, it can detect multiple lamp beads at one time, which also improves work efficiency. The electrical sensor set in the detection plate is connected to a computer terminal to display the detection data in real time.

[0015] 2. The deceleration device of this invention uses a U-shaped plate, a U-shaped rod, a circular plate, a spring, and a rubber roller in conjunction with a grooved plate. As the rubber roller moves downwards, it contacts the arc surface of the grooved plate. Under the constraint of the grooved plate, the U-shaped rod slides towards the center within the U-shaped plate, stretching the spring on the circular plate. Under the spring's pulling force, the rubber roller rolls downwards against the surface of the grooved plate. Friction slows the downward rolling speed of the rubber roller, causing the honeycomb copper sheet to move more slowly as it descends. The honeycomb copper sheet gently adheres to the circuit board of the LED display panel, preventing damage to the circuit board from impacts.

[0016] 3. The deceleration device of the present invention uses a double L-shaped rod and a round shell in conjunction with a sponge ring to make the double L-shaped rod drive the round shell to move downward, and the round shell drives the sponge ring to move downward. The sponge ring wipes lubricating oil on the surface of the round rod to prevent the surface of the round rod from aging and rusting, which would cause the slip ring to slide downward unsmoothly.

[0017] 4. The dust blowing device of the present invention uses a support plate, a long shell and a U-shaped tube in conjunction with a filter screen to make the support plate drive the long shell to move downward, and the long shell drives the U-shaped tube to move downward. The filter screen filters the dust in the airflow, and the long shell blows the airflow to the surface of the LED display panel during the downward movement, preventing dust from clogging the gaps between the LED beads and causing poor detection effect of the detection platform.

[0018] 5. The soot blowing device of the present invention uses a connecting plate and an L-shaped plate in conjunction with a straight plate to make the straight plate support the L-shaped plate to move downward, and the L-shaped plate supports the connecting plate to move downward, so that the connecting plate supports the long shell to move downward, thus preventing the support plate from being unstable and causing poor blowing effect on the long shell.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1-11 As shown, one embodiment of the present invention provides: an automated alignment LED lighting detection platform, comprising: a base 1, wherein a limiting component 2 is disposed in the middle of the top surface of the base 1; Top plate 3 is fixed to the top surface of base platform 1; The drive device 4 is inserted through and fixed in the middle of the top surface of the top plate 3, and a telescopic end is provided in the middle of the bottom surface of the drive device 4. Disc 5 is fixed to the bottom surface of the telescopic end of the drive device 4; The detection plate 6 is fixed to the bottom surface of the disc 5, and the disc 5 is located in the middle of the top surface of the detection plate 6. The honeycomb copper sheet 7 is fixedly installed on the bottom surface of the detection plate 6. The honeycomb copper sheet 7 is located directly above the limiting component 2. Multiple honeycomb holes are opened inside the honeycomb copper sheet 7. A guide assembly is provided on the top surface of the detection plate 6; The guiding assembly includes: a bent plate 8, a slip ring 9, and a round rod 10. The bent plate 8 is fixed on the top surface of the detection plate 6. The slip ring 9 passes through and is fixed on the top surface of the corresponding bent plate 8. The round rod 10 is fixed between the base platform 1 and the top plate 3. The slip ring 9 and the round rod 10 are slidably connected. The slip ring 9 and the round rod 10 cooperate to guide the honeycomb copper sheet 7 to move in the vertical direction. I-shaped tube 11 is fixed below the outer wall of round rod 10 and is used to restrict the downward movement of slip ring 9; When using this testing platform, the operator places the LED display panel in the limiting component 2. The operator then activates the drive device 4 on the top plate 3. The telescopic end of the drive device 4 begins to move downwards, driving the disc 5 downwards. The disc 5 drives the detection plate 6 downwards, which in turn drives the honeycomb copper sheet 7 downwards. During this downward movement, multiple honeycomb holes in the honeycomb copper sheet 7 insert into the gaps between the LED beads on the display panel. One conductive copper sheet is connected to the positive terminal of the power supply, and another is connected to the negative terminal. After the detection plate 6 is in position, one conductive copper sheet contacts the negative terminal of the LED bead pin, and another contacts the positive terminal. Due to the large arc area of ​​the conductive copper sheet, compared to the probe, it can complete the test even with a small deviation in the pin. Furthermore, it can test multiple LED beads at once, improving work efficiency. However, LED bead pins are relatively thin, and when there is a deviation in the soldering of the LED bead pins, existing technologies... In the detection process using a probe, it is difficult for the probe to fully contact each LED pin during its movement. The multiple honeycomb holes of the honeycomb copper sheet 7 cover multiple LEDs. During the downward movement, the multiple honeycomb holes of the honeycomb copper sheet 7 will inevitably contact multiple LED pins, and the contact area is further increased by the arc surface of the conductive copper sheet, thereby realizing the individual detection of each LED. At the same time, the detection plate 6 drives the bent plate 8 to move downward, and the bent plate 8 drives the slip ring 9 to move downward. The slip ring 9 slides downward on the surface of the round rod 10. Under the constraint of the round rod 10, the detection plate 6 is ensured to be stable and move downward along the predetermined trajectory. During the downward movement, the slip ring 9 contacts the surface of the I-shaped tube 11. The I-shaped tube 11 restricts the slip ring 9 from moving further downward, so that the honeycomb copper sheet 7 does not excessively squeeze the circuit board of the LED display board, and the honeycomb copper sheet 7 can contact the offset pins, preventing the problem of LEDs with offset pins from not being detected. The outer wall of the curved plate 8 is provided with a deceleration device 12, which is used to slow down the downward movement speed of the honeycomb copper sheet 7. A dust blowing device 13 is provided on the back of the deceleration device 12, which is used to blow away the dust in the gaps of the LED display board lamp beads.

[0023] Working principle: The LED display board is placed in the limiting component 2. The telescopic end of the driving device 4 drives the disc 5 to move downward. The disc 5 drives the detection plate 6 to move downward. The detection plate 6 drives the honeycomb copper sheet 7 to move downward. One conductive copper sheet is connected to the positive terminal of the power supply, and another conductive copper sheet is connected to the negative terminal of the power supply. After the detection plate 6 moves into position, one conductive copper sheet contacts the negative terminal of the LED bead pin, and the other conductive copper sheet contacts the positive terminal of the LED bead pin. Due to the large arc area of ​​the conductive copper sheet, it can complete the detection when the pin deviates slightly, compared to the probe. At the same time, it can detect multiple LED beads at one time, which also improves the work efficiency. The detection plate 6 drives the bent plate 8 to move downward. The bent plate 8 drives the slip ring 9 to move downward. The slip ring 9 slides downward on the surface of the round rod 10. During the downward movement, the slip ring 9 contacts the surface of the I-shaped tube 11. An electrical sensor is set in the detection plate 6. The detection data can be transmitted to the computer terminal for personnel to view through the electrical sensor.

[0024] like Figure 1-11 As shown, the second embodiment of the present invention provides: the deceleration device 12 includes: a spiral plate 121, the spiral plate 121 is a hollow structure, the internal cavity of which extends through the upper and lower ends of the spiral plate 121 in the vertical direction, and the vertical end of the bent plate 8 is located inside the spiral plate 121 and is fixedly connected to the interior of the spiral plate 121. U-shaped rod 122, which is installed through and slidably mounted on the inner wall of the U-shaped plate 121, with the bent end of the U-shaped rod 122 located on the side close to the drive device 4; Circular plate 123 is fixed to the outer wall of U-shaped rod 122; Spring 124 is fixed on the side of the circular plate 123 that is far away from each other, and the end of spring 124 that is far away from the circular plate 123 is fixedly connected to the side of the U-shaped plate 121 that is close to each other. Rubber roller 125 is rotatably mounted on U-shaped rod 122; The groove plate 126 is fixed on the top surface of the base platform 1. The top surface of the groove plate 126 is provided with an arc surface. The groove plate 126 is located on the movement trajectory of the rubber roller 125. As the bending plate 8 moves the slip ring 9 downwards, the bending plate 8 also moves the spiral plate 121 downwards. The spiral plate 121 moves the U-shaped rod 122 downwards, which in turn moves the circular plate 123 downwards. The circular plate 123 moves the spring 124 downwards, and the U-shaped rod 122 moves the rubber roller 125 downwards. During its downward movement, the rubber roller 125 contacts the arc surface of the groove plate 126. Under the constraint of the groove plate 126, the U-shaped rod 122 slides towards the center within the spiral plate 121. The U-shaped rod 122 then moves the circular plate 123 towards the center. The spring 124 on plate 123 is stretched, and the rubber roller 125 rolls downward against the surface of the groove plate 126. Under the action of friction, the downward rolling speed of the rubber roller 125 is slowed down, so that the honeycomb copper sheet 7 moves downward more slowly. The honeycomb copper sheet 7 will gently stick to the circuit board of the LED display board when it moves downward, thus avoiding the problem of the honeycomb copper sheet 7 hitting the circuit board of the LED display board and causing damage to the circuit board of the LED display board during the automatic current detection of the LED display board by the detection platform.

[0025] A double L-shaped rod 127 is fixed on each side of the spiral plate 121 that is far apart from each other. A round shell 128 is fixed on the upper part of the outer wall of the double L-shaped rod 127. A sponge ring 129 is fixed on the inner wall of the round shell 128. The inner wall of the sponge ring 129 slides in contact with the outer wall of the round rod 10. The sponge ring 129 absorbs lubricating oil. While the U-shaped plate 121 drives the U-shaped rod 122 downward, the U-shaped plate 121 drives the double L-shaped rod 127 downward, the double L-shaped rod 127 drives the circular shell 128 downward, and the circular shell 128 drives the sponge ring 129 downward. The sponge ring 129 wipes the lubricating oil on the surface of the circular rod 10, thereby avoiding the problem of the slip ring 9 not sliding smoothly downward due to aging and rusting of the surface of the circular rod 10 during the automatic current detection of the LED display board by the detection platform.

[0026] The soot blowing device 13 includes: a support plate 131, which is fixed to the back of the spiral plate 121; The long shell 132 is fixed to the bottom surface of the support plate 131; U-shaped tube 133, which is inserted through and fixed to the outer wall of long shell 132, has an air inlet on its outer wall and is used to connect to an air pump. The filter screen 134 is fixed to the inner wall of the long shell 132. The long shell 132 is located behind the detection plate 6. The long shell 132 is set to tilt upwards, and the air outlet of the long shell 132 is aligned with the LED display panel in the limiting assembly 2. An air pump is connected to the air inlet of the U-shaped tube 133. When the U-shaped plate 121 moves the U-shaped rod 122 downward, the U-shaped plate 121 moves the support plate 131 downward, the support plate 131 moves the long shell 132 downward, the long shell 132 moves the U-shaped tube 133 downward, and the long shell 132 moves the filter screen 134 downward. The air pump outputs airflow into the U-shaped tube 133, and the U-shaped tube 133 outputs airflow into the long shell 132. The filter screen 134 filters the dust in the airflow. As the long shell 132 moves downward, it blows airflow onto the surface of the LED display panel, cleaning the dust from the gaps between the LED beads. This avoids the problem of poor detection effect caused by dust clogging the gaps between the LED beads during the automatic current detection of the LED display panel.

[0027] A connecting plate 135 is provided in the middle of the outer wall of the long shell 132. An L-shaped plate 136 is fixed on the front of the connecting plate 135. A straight plate 137 is fixed on the bottom surface of the L-shaped plate 136. The bottom surface of the straight plate 137 is fixedly connected to the top surface of the detection plate 6. While the support plate 131 moves the long shell 132 downward, the detection plate 6 supports the straight plate 137 downward, the straight plate 137 supports the L-shaped plate 136 downward, and the L-shaped plate 136 supports the connecting plate 135 downward. This causes the connecting plate 135 to support the long shell 132 downward, thus avoiding the problem of poor air blowing effect of the long shell 132 caused by the instability of the support plate 131 supporting the long shell 132 during the automatic current detection of the LED display board.

[0028] Working principle: The curved plate 8 drives the U-shaped plate 121 to move downward, the U-shaped plate 121 drives the U-shaped rod 122 to move downward, the U-shaped rod 122 drives the circular plate 123 to move downward, the circular plate 123 drives the spring 124 to move downward, and the U-shaped rod 122 drives the rubber roller 125 to move downward. During the downward movement, the rubber roller 125 contacts the arc surface of the groove plate 126. Under the restriction of the groove plate 126, the U-shaped rod 122 slides towards the middle in the U-shaped plate 121. The U-shaped rod 122 drives the circular plate 123 to slide towards the middle, and the spring 124 on the circular plate 123 is stretched. The rubber roller 125 rolls downward against the surface of the groove plate 126. Under the action of friction, the downward rolling speed of the rubber roller 125 is slowed down, so that the honeycomb copper sheet 7 moves downward more slowly as it moves downward. The U-shaped plate 121 drives the double L-shaped rod 127 to move downward, the double L-shaped rod 127 drives the round shell 128 to move downward, the round shell 128 drives the sponge ring 129 to move downward, and the sponge ring 129 wipes the lubricating oil on the surface of the round rod 10. An air pump is connected to the air inlet of the U-shaped tube 133. The U-shaped plate 121 drives the support plate 131 to move downward. The support plate 131 drives the long shell 132 to move downward. The long shell 132 drives the U-shaped tube 133 to move downward. The long shell 132 drives the filter screen 134 to move downward. During the downward movement, the long shell 132 blows airflow onto the surface of the LED display panel. The detection plate 6 supports the straight plate 137 to move downwards, the straight plate 137 supports the L-shaped plate 136 to move downwards, the L-shaped plate 136 supports the connecting plate 135 to move downwards, and the connecting plate 135 supports the long shell 132 to move downwards.
