Description

Technical Field

[0001] The invention relates to the technical field of LED lamp detection, and in particular to a device for testing the luminous performance of an LED lamp. Background Art

[0002] Light strips refer to LED lights that are welded on copper wires or strip-shaped flexible circuit boards using a special processing technique and then connected to a power source to emit light. The main features are that they are soft and can be curled like wires; they can be cut and extended; the bulbs and circuits are completely covered in flexible plastic, with good insulation and waterproof properties, and are safe to use; they are weather-resistant; they are not easy to break and have a long service life; and they are easy to make graphics, text, and other shapes. Since the LED light strip is a series-parallel structure, when a short circuit occurs in a group of circuits, the voltage of other LEDs in the same group will increase, the brightness of the LED will increase, and the corresponding heat generation will also increase, causing the current of the short-circuited lamp bead to double, that is, 20mA to 40mA, and the brightness of the lamp bead will become very bright, but at the same time the heat generation will also increase dramatically, and in severe cases the circuit board will be burned out within a few minutes.

[0003] For example, application number CN116429382B discloses a device for testing the luminous performance of a LED flexible screen. By means of the device for testing the luminous performance of a LED flexible screen, a first detection mechanism is set up. When it is necessary to test the luminous performance of the flexible screen body, the flexible screen body is first clamped and limited by a clamping mechanism. Then, a water tank and a fixed tube are moved downward by a lifting mechanism, so that each fixed tube covers the LED lamp beads separately, and the sealing ring is tightly fitted with the surface of the flexible screen body. Then, the electromagnet is energized, and after being energized, the electromagnet attracts the iron block, from The movable plate is moved upward, and at the same time, the second spring is compressed. At this time, negative pressure is formed under the movable plate, so that the fixed tube tightly adsorbs the flexible screen body. Finally, the water tank and the fixed tube are reciprocated up and down by the lifting mechanism, so that the flexible screen body can be reciprocated in the weft direction. At the same time, the movable plate and the flexible screen body are moved by the moving mechanism to change the test position. During the bending process, the brightness of the LED lamp beads can be detected by the brightness sensor, which makes the test more convenient and the test effect is better. This kind of LED flexible screen luminous performance test The device is provided with a second detection mechanism, etc., and after the latitudinal bending test is completed, the first motor is started, and the rotation of the first motor drives the rotation of the first threaded rod, thereby driving the moving block and the pushing block to move, so that the inclined plane reciprocates and abuts against the lower end of the moving rod. When the lower end of the moving rod abuts against the inclined plane, the moving rod and the pushing plate are pushed to move upward. At the same time, the first spring is compressed. When the lower end of the moving rod passes over the inclined plane, the moving rod and the pushing plate can move downward and reset under the action of the first spring. In this way, the flexible screen body can be reciprocated in the longitudinal direction. At the same time, by setting multiple The push plate can perform bending tests at different positions in the longitudinal direction, and during the bending process, the brightness of the LED lamp beads can be detected by the brightness sensor, which makes the test more convenient and the test effect better. This kind of LED flexible screen luminous performance testing device, by setting a blowing mechanism, etc., before the test, when the fixed tube moves downward, the blower is started to allow external air to enter the hose through the connecting tube and be sprayed on the surface of the flexible screen body through the blowing tube, so that the surface of the flexible screen body can be automatically blown and cleaned before the test, so that the test result is more accurate and reliable.

[0004] The above-mentioned comparative documents can only detect chip-mounted LED screens. In existing devices, when detecting circular LEDs, the LED light strips are usually detected by the naked eye by powering on for a long time. Observing the lamp tubes for a long time will cause a certain degree of damage to the human eye. At the same time, in order to ensure the detection efficiency, several lamp tubes will be powered on at the same time during the detection, which makes it difficult to observe some tiny weak light areas, affecting the detection effect.

A marking groove 808 is opened on the inner side of the temperature collecting arc block 802, and a marking block 809 is fixedly connected to one end of the shaking spring 806 near the inner ring of the temperature collecting arc block 802. Feed grooves 810 are opened in the middle and upper parts of both sides of the marking block 809, and an injection port 811 is opened at the upper end of the feed groove 810, and the injection port 811 is connected with the feed groove 810 and the connecting groove 804.

[0046] In this embodiment: when the circular light strip 9 is short-circuited and generates high temperature, the heat-conducting arc 801 will fit the circular light strip 9 to conduct heat, and transmit it to the lifting block 703 through the heat-collecting arc block 802. When the lifting block 703 is lifted upward, the marking powder inside the storage tank 803 will enter the feed tank 810 through the connecting groove 804, and accumulate at the bottom of the injection port 811. The heat-collecting arc block 802 will be lifted upward, and the shaking spring 806 inside the hollow groove 805 will first contract and accumulate force under the action of inertia, and the marking block 809 will contract inside the marking groove 808. When the force is accumulated to a certain extent, the marking block 809 will be pushed to spray the marking powder at the bottom of the injection port 811 to the short-circuit point of the circular light strip 9. When powder needs to be added, it can be added to the inside of the storage tank 803 through the sealing cover 807.

[0047] Working principle: when in use, place the circular light strip 9 on the processing box 2, rotate the closing plate 4, which will drive the rotating shaft 301 to assist in its rotation, and at the same time drive the center plate 304 on the first circular piece 302 to rotate. When the center plate 304 rotates, it will rotate and pull the spring plate 306, driving the sliding plate 305 on the second circular piece 303 to rotate, and the linkage plate 308 will push forward according to the change in the rotation angle, and the linkage plate 308 will rotate and push the connecting block 309, and the connecting block 309 will push the elastic block 311 on the adjustment slot 310. The elasticity of the elastic block 311 itself will clamp the plug interface 10, and while pushing, the plug interface 10 will be plugged into the power socket 6, and the friction rubber 314 will prevent The stop plug interface 10 slips with the large semicircular block 312, and the small semicircular block 313 stretches and seals the large semicircular block 312 during placement. At the same time, the plug interface 10 will be tightly attached to the power socket 6 under the action of the stable structure 3, and the internal temperature of the processing box 2 is controlled by the temperature controller 5. When the circular light strip 9 short-circuits, a large amount of heat will be generated. When the circular light strip 9 short-circuits and generates high temperature, the heat-conducting arc 801 will fit the circular light strip 9 for heat conduction, and transmit it to the jacking block 703 through the heat-collecting arc block 802, and then transmit it to the inside of the heat-conducting groove 706, and then transmit it to the heat-conducting block 707 through the heat-conducting groove 706. When the heat-conducting block 707 transmits heat, it will be transmitted to the folding block 710 inside the contact groove 709, and then through the heat-conducting plate 711. The heat is transferred to the ammonia bag 712. The ammonia bag 712 is subjected to the heat and expands inside the expansion groove 713. When it expands to a certain extent, it squeezes the trigger block 722 inside the trigger groove 718. The trigger block 722 pushes the arc block 720 on the arc groove 721 to disengage, canceling the limit between the hook block 719 and the trigger groove 718. At the same time, the pressing rod 716 on the pressing groove 717 will lift upward, and the ejection spring 715 inside the ejection groove 714 will push the ejection block 723 upward. At the same time, the trapezoidal block 724 and the fixing plate 725 transmit the upward force to the lifting block 703 to lift it. After lifting, the heat conduction groove 706 and the heat conduction block 707 will be separated to isolate the heat. The source contacts, causing the inside of the ammonia bag 712 to cool and shrink, canceling the trigger block 722, and pressing the pressing rod 716 downward by stepping on the pedal 705, so that the arc block 720 and the arc groove 721 are clamped again, and when the lifting block 703 is lifted upward, the marking powder inside the storage tank 803 will enter the feeding tank 810 through the connecting groove 804, and accumulate at the bottom of the injection port 811. The temperature collecting arc block 802 will be lifted upward, and the shaking spring 806 inside the hollow groove 805 will first contract and accumulate force under the action of inertia, and the marking block 809 will contract inside the marking groove 808. When the force is accumulated to a certain extent, the marking block 809 will be pushed to spray the marking powder at the bottom of the injection port 811 to the short circuit of the circular light strip 9.When powder needs to be added, it can be added to the storage tank 803 through the sealing cover 807.
