Description

Technical Field

[0001] The invention relates to the technical field of lamp bead aging testing, in particular to an aging testing device for LED lamp bead in full-brightness state. Background Art

[0002] During the production and manufacturing process of LED lamps, due to factors such as the characteristics of LED materials and operating processes, the brightness of LED lamps may decrease or even turn off during use. In addition to the reasons themselves, the LED lamps may also malfunction during use due to wear and tear during the production process. These problems will not only affect the normal use of LED lamps, but also shorten their service life and accelerate aging.

[0003] In conventional LED lamp aging tests, the LED lamp is usually manually connected to a power source, its brightness is visually checked, and then it is manually removed. This kind of detection is relatively rough and has a single detection method. It can only detect the brightness of an instantaneously started LED lamp, and it wastes manpower and is inefficient, and cannot achieve efficient and accurate detection. Summary of the invention

[0004] The purpose of the present invention is to provide an aging test device for LED lamp beads in full-brightness state to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an aging test device for LED lamp beads in full-brightness state.

[0006] The aging test device detects LED lamp beads. The test device includes a main body mechanism, an aging detection mechanism, a clamping mechanism, and a sub-packaging mechanism. The main body mechanism is connected to the aging detection mechanism, the main body mechanism is connected to the clamping mechanism, the main body mechanism is connected to the sub-packaging mechanism, and the aging detection mechanism is connected to the clamping mechanism.

[0007] In the aging test device, this mechanism is used to perform aging tests on LED lamp beads. Aging detection of LED lamp beads is indispensable. Through aging detection, LED lamp beads with unstable performance or prone to failure under normal use can be screened out, which is beneficial to ensure the quality and reliability of the final product. The main mechanism is the installation basis of the entire device. The aging detection mechanism is used to perform aging detection on LED lamp beads. The clamping mechanism fixes the LED lamp beads during testing, and the packaging mechanism is used to separate defective products from qualified products.

[0008] Furthermore, the main body mechanism includes a support base, a top plate and side baffles. The support base is placed on the ground. The support base and the top plate are fastened together by the side baffles. The support base is connected to the aging detection mechanism, and the support base is connected to the packaging mechanism.

[0009] In the main body, an aging detection mechanism is connected to the support base to provide a support basis for the aging detection mechanism. The top plate and the support base are fastened together by side baffles, so that the aging detection is fixed in one area to reduce errors caused by external interference.

[0010] Furthermore, the aging detection mechanism includes a detection base, a detection plug, and a lifting hydraulic cylinder. The detection base and the detection plug are connected through the lifting hydraulic cylinder. There are several detection plugs, and several detection plugs are connected along the detection base. The cross-section of the detection base is rectangular. The length of the detection base is greater than the length of several detection plugs after connection. The detection plug is provided with a socket, and a wire is connected to the bottom of the socket. The end of the LED lamp bead is connected to the inner wall wire of the socket of the detection plug, and the detection plug wire extends to the outside of the detection plug. There are several lifting hydraulic cylinders, and the number of lifting hydraulic cylinders is the same as the number of detection plugs. The fixed end of the lifting hydraulic cylinder is tightly connected to the detection base, the output end of the lifting hydraulic cylinder is tightly connected to the detection plug, the detection base is connected to the clamping mechanism, the detection plug is connected to the lifting hydraulic cylinder, and the detection plug is connected to the clamping mechanism.

[0011] In the aging detection mechanism, a detection base is placed on a supporting base, and several detection sockets are connected to the detection base through a lifting hydraulic cylinder. One end of the lifting hydraulic cylinder is tightly connected to the detection base, and an output end of a lifting hydraulic cylinder is tightly connected to a detection socket. The detection socket can be moved up and down by the lifting hydraulic cylinder. The socket on the detection socket is used to insert LED lamp beads to power on and light them up. After the device is started, the device is powered on, and the LED lamp beads are placed in the detection sockets and connected through wires. After power is turned on, the LED lamp beads will light up. If there are damaged LED lamp beads, they will not light up after power is turned on. At this time, the circuit where the LED lamp beads are located is broken, and the signal is transmitted to the corresponding lifting hydraulic cylinder. The lifting hydraulic cylinder is started, driving the detection socket and the LED lamp beads inserted in the detection socket to move up, thereby marking the defective LED lamp beads that cannot light up by themselves.

[0012] Furthermore, the aging detection mechanism also includes a power-on mechanism, which is connected to the detection socket. The power-on mechanism includes a conductive hydraulic cylinder and a driving power supply. The conductive hydraulic cylinder and the supporting base are fastened together by a fixed plate. The output end of the conductive hydraulic cylinder and the driving power supply are fastened together. The output end of the driving power supply faces the detection socket. The positive pole of the driving power supply is fastened with a wire, and the negative pole of the driving power supply is connected to the external wire of the detection socket.

[0013] In the energizing mechanism, the device is used to energize the aging detection mechanism, and pushes the driving power supply forward by the conducting hydraulic cylinder to connect its negative pole with the external wire of the detection plug. By conducting the hydraulic cylinder, two tests can be completed: stroboscopic energization and continuous energization; stroboscopic energization is to drive the driving power supply forward after the conducting hydraulic cylinder drives the driving power supply forward, and then drives the driving power supply back to cut off the power supply of the circuit. This operation is repeated many times. If the brightness of the light is low or not bright when it is on, it proves that it is easy to age and is unstable. At this time, the resistance in the circuit becomes larger, and the signal is transmitted to the corresponding lifting hydraulic cylinder. The lifting hydraulic cylinder starts, driving the detection plug and the plug in the detection plug. The LED lamp beads in the test plug-in table move up to mark the LED lamp beads whose brightness is weakened when the stroboscopic power is turned on; after the conduction hydraulic cylinder pushes the driving power supply and the external wire of the detection plug-in table to connect, the conduction hydraulic cylinder maintains this state, so that the circuit is continuously turned on for a certain period of time. When the power is turned on for a long time, if the brightness of the LED lamp beads becomes dim or even off, it proves that it is easy to age and is unstable. At this time, the resistance value in the circuit becomes larger, and the signal is transmitted to the corresponding lifting hydraulic cylinder. The lifting hydraulic cylinder starts, driving the detection plug-in and the LED lamp beads inserted in the detection plug-in to move up, so as to mark the LED lamp beads whose brightness is weakened when the power is turned on for a long time.

[0014] Furthermore, the clamping mechanism includes a clamping rod, a clamping inclined plate and a flexible pad. There are several clamping rods, several clamping inclined plates, and several flexible pads. The number of clamping rods, clamping inclined plates and flexible pads is the same, and the number of clamping rods, clamping inclined plates and flexible pads is twice that of the detection plug. Two clamping rods are symmetrically installed at both ends of a detection plug. The bottom of the clamping rod is a flexible material. The bottom of the clamping rod is tightly connected to the detection base. The two clamping inclined plates are tightly connected to both ends of a detection plug respectively. The clamping inclined plate is provided with a slide groove. The clamping inclined plate and the clamping rod are slidably connected through the slide groove, and the flexible pad is tightly connected to the clamping end of the clamping rod.

[0015] In the clamping mechanism, the clamping mechanism is used to clamp and fix the LED lamp beads that are being tested or have passed the test to prevent them from being mistakenly collected when the subpackaging mechanism collects defective LED lamp beads. The flexible pad is fixedly connected to the clamping end of the clamping rod. Because the LED lamp beads are small, direct clamping of the clamping rod may cause wear to the LED lamp beads. At the same time, the clamping rod is tightly connected to the detection base, the clamping inclined plate is tightly connected to the detection plug-in, the clamping rod and the clamping inclined plate are slidably connected, and the clamping inclined plate is tilted at the detection plug-in. The two corresponding The clamping inclined plate is symmetrically arranged on the detection platform. Under normal circumstances, the lifting hydraulic cylinder is not started. At this time, the clamping rod clamps the LED lamp beads through the flexible pad. After the defective LED lamp beads are detected, the lifting hydraulic cylinder starts to lift up. At this time, the detection platform moves upward with the clamping inclined plate, and the clamping rod and the clamping inclined plate are slidably connected. In the process of the clamping inclined plate moving up, the distance between the clamping ends of the two corresponding clamping rods becomes larger. At this time, the defective LED lamp beads cannot be clamped, and the lifting hydraulic cylinder that is not started remains clamped.

[0016] Furthermore, the packaging mechanism includes a lamp bead suction device, which includes a vacuum pump, an anti-suction filter, a vacuum pipe and a vacuum filter. The vacuum pump is tightly connected to the support base, the vacuum pump output end is tightly connected to the vacuum pipe, the end of the vacuum pipe away from the vacuum pump is tightly connected to the vacuum filter, the anti-suction filter is placed inside the vacuum filter, the anti-suction filter is tightly connected to the inner wall of the vacuum filter, the cross-section of the vacuum filter is rectangular, and the length and width of the rectangular cross-section of the vacuum filter are larger than the detection base.

[0017] In the packing mechanism, the lamp bead suction device is used to absorb the defective LED lamp beads and make them leave the detection socket. After the aging test is completed, the lifting hydraulic cylinder will lift the defective LED lamp beads, and the clamping mechanism on the lifted LED lamp beads will not clamp the LED lamp beads. The vacuum pump starts to absorb. An anti-suction filter is provided in the vacuum filter, and the length and width of the rectangular cross-section of the vacuum filter are larger than the detection base. Therefore, the defective LED lamp beads on the detection base can be absorbed at one time. The anti-suction filter is used for filtering to prevent the LED lamp beads from being sucked into the vacuum pipe or even the vacuum pump. The defective LED lamp beads are sucked out of the detection socket through the vacuum pump.

[0018] Furthermore, the packaging mechanism also includes a defective product box and a qualified product box. The cross-section of the defective product box is larger than the cross-section of the vacuum filter, and the cross-section of the qualified product box is larger than the cross-section of the vacuum filter. The defective product box is tightly connected to the support base, and the qualified product box is tightly connected to the support base. The qualified product box includes a box body, an adjustable trampoline, an angle adjustment hydraulic cylinder and a buffer fan. The inner wall of the box is provided with a flexible material, the adjustable trampoline is tilted, the adjustable trampoline and the box body are slidably connected, one end of the angle adjustment hydraulic cylinder is tightly connected to the inner wall of the box, the output end of the angle adjustment hydraulic cylinder is tightly connected to the adjustable trampoline, the buffer fan is tightly connected to the inner wall of the box, and the air outlet of the buffer fan is facing the direction of the adjustable trampoline.

[0019] The driving device is used to drive the lamp bead suction device to move, and place the defective LED lamp beads and qualified LED lamp beads into the defective box and the qualified box respectively. The rotating motor drives the rotating platform to rotate. The rotating platform and the mechanical arm are tightly connected, so the mechanical arm is rotated together. The mechanical arm and the vacuum pipe are tightly connected, so it can rotate with the vacuum pipe and the vacuum filter. First, the vacuum filter that collects the defective LED lamp beads is rotated to the top of the defective box, and the driving is stopped. The defective LED lamp beads fall down. After that, the lifting hydraulic cylinder lifts the detection plug where the qualified LED lamp beads are located, and the vacuum pump is started again to collect the qualified LED lamp beads. After that, it is moved to the top of the qualified product box through the driving device. At this time, the buffer fan is started, and the wind blows in the direction of the adjustable trampoline. The lamp bead suction device stops driving, and the qualified LED lamp beads fall down. During the falling process, the wind blown by the buffer fan makes the LED lamp beads move towards the adjustable trampoline The bed moves and falls on the adjustable trampoline to cushion the falling LED lamp beads. In the case where there are a large number of qualified LED lamp beads falling, the buffer fan increases the air volume, and the angle adjustment hydraulic cylinder drives the adjustable trampoline to move, changing the angle between the adjustable trampoline and the bottom of the box, so that the angle becomes smaller, the slope of the adjustable trampoline becomes gentler, and the flexible material is also covered on the bottom of the box. A section of the flexible material close to the adjustable trampoline is placed on the adjustable trampoline. During the process of adjusting the angle of the adjustable trampoline, a part of the flexible material is always on the adjustable trampoline. During the falling process of the LED lamp beads, the gentle slope and the increased air volume can fully allow the LED lamp beads to fall onto the adjustable trampoline and cushion most of the falling force. At the same time, the connection between the flexible material and the adjustable trampoline ensures that when the angle of the adjustable trampoline changes, there will be no place at the bottom of the box that is not covered with the flexible material, so that qualified LED lamp beads can better roll to the bottom of the box.

[0020] Compared with the prior art, after startup, the present invention first inserts a number of LED lamp beads into the detection socket respectively, and turns on the hydraulic cylinder to push the driving power supply forward, so that its negative pole is connected to the external wire of the detection socket. After power is turned on, the LED lamp beads light up, and the damaged LED lamp beads will not light up after power is turned on. The circuit where the LED lamp beads are located is broken, and the signal is transmitted to the corresponding lifting hydraulic cylinder. The lifting hydraulic cylinder drives the detection socket to move up, and the distance between the clamping ends of the corresponding two clamping rods becomes larger. At this time, the defective LED lamp beads cannot be clamped, and then the detection under stroboscopic power-on and continuous power-on conditions is carried out. The stroboscopic power-on performs aging detection by repeatedly turning on and off the power, and the continuous power-on performs aging detection by turning on the power for a long time. During the circuit conduction process, if the brightness of the LED lamp beads becomes dim or even not bright, it proves that they are prone to aging and are unstable. At this time, the resistance value in the circuit becomes large, and the signal is transmitted to The corresponding lifting hydraulic cylinder is started, and the detection plug-in table is driven to move up. The clamping mechanism does not clamp the LED lamp beads that move up. After the aging test is completed, they need to be packaged. The vacuum pump is started to absorb the defective LED lamp beads and make them adhere to the anti-suction filter net. Then the driving device drives the rotation to move the vacuum filter to the top of the defective box. Then the driving is stopped, and the defective LED lamp beads fall into the defective box. Then, the lifting hydraulic cylinder lifts the detection plug-in table where the qualified LED lamp beads are located, and the vacuum pump is started again to collect the qualified LED lamp beads. Then it is moved to the top of the qualified product box through the driving device. The buffer fan and the adjustable trampoline increase the air volume and the slowness according to the number of qualified LED lamp beads absorbed, so that the LED lamp beads can fully fall onto the adjustable trampoline during the falling process, buffer most of the falling force, and then roll down to the inner wall of the box along the adjustable trampoline.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0031] See also Figure 1-7 , the present invention provides a technical solution:

[0032] The aging test device detects the LED lamp bead 1, and the test device includes a main body mechanism 2, an aging detection mechanism 3, a clamping mechanism 4, and a sub-packaging mechanism 5. The main body mechanism 2 is connected to the aging detection mechanism 3, the main body mechanism 2 is connected to the clamping mechanism 4, the main body mechanism 2 is connected to the sub-packaging mechanism 5, and the aging detection mechanism 3 is connected to the clamping mechanism 4.

[0033] In the aging test device, this mechanism is used to perform aging test on LED lamp beads 1. Aging detection of LED lamp beads 1 is indispensable. Through aging detection, LED lamp beads 1 with unstable performance or prone to failure under normal use can be screened out, which is beneficial to ensure the quality and reliability of the final product. The main mechanism 2 is the installation basis of the entire device, the aging detection mechanism 3 is used to perform aging test on LED lamp beads 1, the clamping mechanism 4 fixes the LED lamp beads 1 during testing, and the packaging mechanism 5 is used to separate defective products from qualified products.

[0034] The main body mechanism 2 includes a support base 21, a top plate 22 and a side baffle 23. The support base 21 is placed on the ground. The support base 21 and the top plate 22 are fastened together by the side baffle 23. The support base 21 is connected to the aging detection mechanism 3, and the support base 21 is connected to the packaging mechanism 5.

[0035] In the main body 2, an aging detection mechanism 3 is connected to the support base 21 to provide a support basis for the aging detection mechanism 3. The top plate 22 and the support base 21 are fastened together by the side baffle 23, so that the aging detection is fixed in one area to reduce errors caused by external interference.

[0036] The aging detection mechanism 3 includes a detection base 31, a detection plug-in platform 32, and a lifting hydraulic cylinder 33. The detection base 31 and the detection plug-in platform 32 are connected by the lifting hydraulic cylinder 33. There are several detection plug-ins 32, and several detection plug-ins 32 are connected along the detection base 31. The cross-section of the detection base 31 is rectangular. The length of the detection base 31 is greater than the length of several detection plug-ins 32 after being connected. A socket is provided on the detection plug-in platform 32, and a wire is connected to the bottom of the socket. The end of the LED lamp bead 1 is connected to the inner wall wire of the socket of the detection plug-in platform 32, and the wire of the detection plug-in platform 32 extends to the outside of the detection plug-in platform 32. There are several lifting hydraulic cylinders 33, and the number of lifting hydraulic cylinders 33 is consistent with the number of detection plug-ins 32. The fixed end of the lifting hydraulic cylinder 33 is tightly connected to the detection base 31, and the output end of the lifting hydraulic cylinder 33 is tightly connected to the detection plug-in platform 32. The detection base 31 is connected to the clamping mechanism 4, the detection plug-in platform 32 is connected to the lifting hydraulic cylinder 33, and the detection plug-in platform 32 is connected to the clamping mechanism 4.

[0037] In the aging detection mechanism 3, a detection base 31 is placed on the support base 21, and a number of detection sockets 32 are connected to the detection base 31 through a lifting hydraulic cylinder 33. One end of the lifting hydraulic cylinder 33 is tightly connected to the detection base 31, and an output end of a lifting hydraulic cylinder 33 is tightly connected to a detection socket 32. The detection socket 32 ​​can be moved up and down by the lifting hydraulic cylinder 33. The socket on the detection socket 32 ​​is used to insert the LED lamp bead 1 to power it on and light it up. After the device is started, the device is powered on, and the LED lamp bead 1 is placed in the detection socket 32 ​​and connected through a wire. After power is turned on, the LED lamp bead 1 lights up. If there is a damaged LED lamp bead 1, it will not light up after power is turned on. At this time, the circuit where the LED lamp bead 1 is located is broken, and a signal is transmitted to the corresponding lifting hydraulic cylinder 33. The lifting hydraulic cylinder 33 is started, driving the detection socket 32 ​​and the LED lamp bead 1 inserted in the detection socket 32 ​​to move up, so as to mark the defective LED lamp bead 1 that cannot light up by itself.

[0038] The aging detection mechanism 3 also includes a power-on mechanism 34, which is connected to the detection platform 32. The power-on mechanism 34 includes a conducting hydraulic cylinder 341 and a driving power supply 342. The conducting hydraulic cylinder 341 and the supporting base 21 are fastened together by a fixing plate. The output end of the conducting hydraulic cylinder 341 and the driving power supply 342 are fastened together. The output end of the driving power supply 342 faces the detection platform 32. The positive pole of the driving power supply 342 is fastened with a wire, and the negative pole of the driving power supply 342 is connected to the external wire of the detection platform 32.

[0039] In the power-on mechanism 34, the device is used to energize the aging detection mechanism 3, and pushes the driving power supply 342 forward by the conducting hydraulic cylinder 341, so that its negative pole is connected to the external wire of the detection plug-in platform 32. By conducting the hydraulic cylinder 341, two tests can be completed: stroboscopic power-on and continuous power-on; stroboscopic power-on is to drive the driving power supply 342 forward after the conducting hydraulic cylinder 341 is conducting the circuit, and then drive the driving power supply 342 back to cut off the circuit. This operation is repeated many times. If the brightness of the light is low or not bright when the light is on, it proves that it is easy to age and is unstable. At this time, the resistance in the circuit becomes larger, and the signal is transmitted to the corresponding lifting hydraulic cylinder 33. The lifting hydraulic cylinder 33 is started, driving the detection plug-in platform 32 and the plug-in The LED lamp bead 1 in the detection socket 32 ​​moves up to mark the LED lamp bead 1 whose brightness is weakened by the stroboscopic power-on; after the conductive hydraulic cylinder 341 pushes the driving power supply 342 and the external wire of the detection socket 32 ​​to connect, the conductive hydraulic cylinder 341 is maintained in this state, so that the circuit is continuously conductive for a certain period of time. When the power is on for a long time, if the brightness of the LED lamp bead 1 becomes dim or even not bright, it proves that it is prone to aging and is unstable. At this time, the resistance value in the circuit becomes larger, and the signal is transmitted to the corresponding lifting hydraulic cylinder 33. The lifting hydraulic cylinder 33 starts, driving the detection socket 32 ​​and the LED lamp bead 1 inserted in the detection socket 32 ​​to move up, so as to mark the LED lamp bead 1 whose brightness is weakened by the long-term power-on.

[0040] The clamping mechanism 4 includes a clamping rod 41, a clamping inclined plate 42 and a flexible pad 43. There are several clamping rods 41, several clamping inclined plates 42, and several flexible pads 43. The number of clamping rods 41, clamping inclined plates 42 and flexible pads 43 is the same. The number of clamping rods 41, clamping inclined plates 42 and flexible pads 43 is twice that of the detection platform 32. Two clamping rods 41 are symmetrically installed at both ends of a detection platform 32. The bottom of the clamping rod 41 is made of flexible material. The bottom of the clamping rod 41 is firmly connected to the detection base 31. The two clamping inclined plates 42 are firmly connected to both ends of a detection platform 32 respectively. The clamping inclined plate 42 is provided with a slide groove. The clamping inclined plate 42 and the clamping rod 41 are slidably connected through the slide groove. The flexible pad 43 and the clamping end of the clamping rod 41 are firmly connected.

[0041] In the clamping mechanism 4, the clamping mechanism 4 is used to clamp and fix the LED lamp bead 1 that is being tested or has passed the test to prevent it from being mistakenly collected when the subpackaging mechanism 5 collects the defective LED lamp bead 1. The flexible pad 43 is fixedly connected to the clamping end of the clamping rod 41. Because the LED lamp bead 1 is small, the direct clamping of the clamping rod 41 may cause wear to the LED lamp bead 1.

The two corresponding The clamping inclined plate 42 is symmetrically arranged on the detection platform 32. Under normal circumstances, the lifting hydraulic cylinder 33 is not started. At this time, the clamping rod 41 clamps the LED lamp bead 1 through the flexible pad 43. After the defective LED lamp bead 1 is detected, the lifting hydraulic cylinder 33 starts to lift up. At this time, the detection platform 32 moves upward with the clamping inclined plate 42, and the clamping rod 41 and the clamping inclined plate 42 are slidably connected. In the process of the clamping inclined plate 42 moving upward, the distance between the clamping ends of the two corresponding clamping rods 41 becomes larger. At this time, the defective LED lamp bead 1 cannot be clamped, and the lifting hydraulic cylinder 33 remains clamped if it is not started.

[0042] The packaging mechanism 5 includes a lamp bead suction device 51, which includes a vacuum pump 511, an anti-suction filter 512, a vacuum pipe 513 and a vacuum filter 514.

[0043] In the packaging mechanism 5, the lamp bead suction device 51 is used to suck the defective LED lamp bead 1 and make it leave the detection platform 32. After the aging test is completed, the lifting hydraulic cylinder 33 will lift the defective LED lamp bead 1, and the clamping mechanism 4 on the lifted LED lamp bead 1 will not clamp the LED lamp bead 1. The vacuum pump 511 starts to absorb. An anti-suction filter 512 is provided in the vacuum filter 514, and the length and width of the rectangular cross-section of the vacuum filter 514 are larger than the detection base 31. Therefore, the defective LED lamp bead 1 on the detection base 31 can be sucked at one time. The anti-suction filter 512 is used for filtering to prevent the LED lamp bead 1 from being sucked into the vacuum pipe 513 or even the vacuum pump 511, and the defective LED lamp bead 1 is sucked out of the detection base 32 through the vacuum pump 511.

[0044] The packing mechanism 5 also includes a defective product box 53 and a qualified product box 54. The cross-section of the defective product box 53 is larger than the cross-section of the vacuum filter 514, and the cross-section of the qualified product box 54 is larger than the cross-section of the vacuum filter 514. The defective product box 53 is tightly connected to the support base 21, and the qualified product box 54 is tightly connected to the support base 21.

[0045] The driving device 52 is used to drive the lamp bead suction device 51 to move, and the defective LED lamp beads 1 and the qualified LED lamp beads 1 are placed in the defective box 53 and the qualified box 54 respectively. The rotating motor 522 drives the rotating platform 523 to rotate. The rotating platform 523 and the mechanical arm 521 are tightly connected, so the mechanical arm 521 is rotated together. The mechanical arm 521 and the vacuum pipe 513 are tightly connected, so that the vacuum pipe 513 and the vacuum filter 514 can be rotated. The vacuum filter 514 that collects the defective LED lamp beads 1 is first rotated to The drive is stopped above the defective box 53, and the defective LED lamp bead 1 falls. Then, the lifting hydraulic cylinder 33 lifts the detection plug 32 where the qualified LED lamp bead 1 is located, and the vacuum pump 511 is started again to collect the qualified LED lamp bead 1. Then, it is moved to the top of the qualified box 54 through the driving device 52. At this time, the buffer fan 544 is started, and the wind blows in the direction of the adjustable trampoline 542. The lamp bead suction device 51 stops driving, and the qualified LED lamp bead 1 falls. In the process of falling, the wind blown by the buffer fan 544 makes the LED lamp bead 1 The adjustable trampoline 542 moves toward the adjustable trampoline 542 and falls on the adjustable trampoline 542 to cushion the falling LED lamp beads 1. In the case where there are many qualified falling LED lamp beads 1, the buffer fan 544 increases the air volume, and the angle adjustment hydraulic cylinder 543 drives the adjustable trampoline 542 to move, changing the angle between the adjustable trampoline 542 and the bottom of the box body 541, so that the angle becomes smaller, the slope of the adjustable trampoline 542 becomes gentle, and the flexible material also covers the bottom of the box body 541. A section of the flexible material close to the adjustable trampoline 542 is placed on the adjustable trampoline 542. During the process of adjusting the angle of the trampoline 542, a part of the flexible material is always on the adjustable trampoline 542. During the falling process of the LED lamp bead 1, the gentle slope and increased wind volume can fully allow the LED lamp bead 1 to fall on the adjustable trampoline 542, buffering most of the force of falling. At the same time, the connection between the flexible material and the adjustable trampoline 542 ensures that when the angle of the adjustable trampoline 542 changes, there will be no area at the bottom of the box 541 that is not covered by the flexible material, so that the qualified LED lamp bead 1 can better roll to the bottom of the box 541.

[0046] Working principle of the present invention: after starting, the present invention first inserts a plurality of LED lamp beads 1 into the sockets of the detection socket 32 ​​respectively, and the hydraulic cylinder 341 is turned on to push the driving power supply 342 forward, so that its negative pole is connected to the external wire of the detection socket 32. After power is turned on, the LED lamp bead 1 lights up. The damaged LED lamp bead 1 will not light up after power is turned on. The circuit where the LED lamp bead 1 is located is broken, and the signal is transmitted to the corresponding lifting hydraulic cylinder 33. The lifting hydraulic cylinder 33 drives the detection socket 32 ​​to move upward, and the distance between the clamping ends of the two corresponding clamping rods 41 becomes larger. At this time, the defective LED lamp bead 1 cannot be clamped, and then the detection under the conditions of stroboscopic power-on and continuous power-on is carried out. The stroboscopic power-on performs aging detection by repeatedly turning on and off the power, and the continuous power-on performs aging detection by turning on the power for a long time. During the process of circuit conduction, if the brightness of the LED lamp bead 1 becomes dim or even not bright, it proves that it is easy to age and is unstable. At this time, the resistance value in the circuit becomes larger, and the signal is transmitted to the corresponding lifting hydraulic cylinder 33. The lifting hydraulic cylinder 33 is started, driving the detection insert 32 to move upward, and the clamping mechanism 4 does not clamp the LED lamp bead 1 that moves upward. After the aging test is completed, it needs to be packaged. The vacuum pump 511 is started to absorb the defective LED lamp bead 1 and make it adhere to the anti-absorption filter 512. Then the driving device 52 is driven to rotate, so that the vacuum filter 514 moves to the top of the defective box 53, and then the driving is stopped, and the defective LED lamp bead 1 falls into the defective box 53. After that, the lifting hydraulic cylinder 33 will take the qualified LED lamp bead 1. The detection platform 32 where the D lamp beads 1 are located is lifted, and the vacuum pump 511 is started again to collect qualified LED lamp beads 1. Then, it is moved to the top of the qualified product box 54 through the driving device 52. The buffer fan 544 and the adjustable trampoline 542 increase the air volume and the slowness according to the number of qualified LED lamp beads 1 sucked, so that the LED lamp beads 1 can fully fall onto the adjustable trampoline 542 during the falling process, buffer most of the falling force, and then roll along the adjustable trampoline 542 to the inner wall of the box 541.
