Technical Field
[0001] This utility model belongs to the field of LED lamp bead testing technology, specifically relating to an energy-saving LED lamp bead testing device. Background Technology
[0002] LED chips are simply the abbreviation for Light Emitting Diode, a common name. Their principle is that the voltage across the PN junction creates a potential barrier. When a forward bias voltage is applied, the barrier decreases, and majority carriers in the P and N regions diffuse towards each other. Since electron mobility is much greater than hole mobility, a large number of electrons diffuse into the P region, injecting minority carriers into it. These electrons recombine with holes in the valence band, releasing energy as light. During LED chip manufacturing, this recombination process requires electrical detection.
[0003] Currently, existing energy-saving LED bead testing devices typically require inserting the LED bead's pins into the testing slot and then powering on to perform LED bead quality testing. However, traditional energy-saving LED bead testing devices usually require a protective cover to protect the testing area. However, due to the obstruction of the protective cover during the placement of the LED bead, the operator's operating space is very limited, which may affect the testing efficiency of the LED bead. Utility Model Content

However, traditional energy-saving LED bead testing devices usually require a protective cover to protect the testing area. However, due to the obstruction of the protective cover during the placement of the LED bead, the operator's operating space is very limited, which may affect the testing efficiency of the LED bead.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving LED bead testing device, comprising a workbench, a power supply box installed at the bottom of the workbench, a testing platform installed at the top of the workbench, a rotating disk rotatably connected to the top of the testing platform, multiple testing grooves distributed in a ring on the top of the rotating disk, a first groove and a second groove formed on the top of the workbench, a bidirectional lead screw inserted through one end of the workbench, two threaded connecting blocks threaded to the outer wall of the bidirectional lead screw, a motor installed at the bottom of the workbench, and two protective covers provided on the top of the workbench.
[0006] In a preferred embodiment of the energy-saving LED lamp bead detection device of this utility model, one end of the bidirectional lead screw extends through into the second groove, and a transmission belt is connected between the bidirectional lead screw and the motor output end.
[0007] In a preferred embodiment of the energy-saving LED bead detection device of this utility model, a guide rod is connected to the inner wall of the first groove, and two connecting blocks are sleeved on the outer wall of the guide rod.
[0008] As a preferred embodiment of the energy-saving LED bead testing device of this utility model, four slots are provided at the bottom of the two protective covers, and one end of the connecting block and the threaded connecting block is located inside the slots.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 The present invention provides the following technical solution: an energy-saving LED lamp bead testing device, including a workbench 1, a power supply box 2 installed at the bottom of the workbench 1, a testing platform 3 installed at the top of the workbench 1, a rotating disk 4 rotatably connected to the top of the testing platform 3, a plurality of testing grooves 5 distributed in a ring on the top of the rotating disk 4, a first groove 6 and a second groove 7 opened on the top of the workbench 1, a bidirectional lead screw 10 inserted through one end of the workbench 1, two threaded connecting blocks 11 threadedly connected to the outer wall of the bidirectional lead screw 10, a motor 12 installed at the bottom of the workbench 1, and two protective covers 14 provided on the top of the workbench 1;
[0023] It should be noted that the wiring terminals of the power supply box 2 are connected to the bottom of each detection slot 5 via connecting wires. The detection slot 5 is used to insert the LED beads to be tested. The top of both protective covers 14 is provided with transparent windows, which are made of acrylic sheets.
[0024] It is also important to note that power supply box 2 is an intelligent voltage regulator that can accurately provide a stable voltage according to the testing requirements, avoiding extra energy consumption caused by voltage fluctuations. When testing LED beads of different specifications, the power supply can automatically adjust the output voltage to ensure that the beads work under the rated voltage, preventing energy waste caused by excessive voltage, thereby achieving energy saving.
[0025] Preferably, one end of the bidirectional lead screw 10 extends through into the second groove 7, and a transmission belt 13 is connected between the bidirectional lead screw 10 and the output end of the motor 12. A guide rod 8 is connected to the inner wall of the first groove 6, and two connecting blocks 9 are sleeved on the outer wall of the guide rod 8. Four slots 15 are opened at the bottom of the two protective covers 14, and one end of the connecting block 9 and the threaded connecting block 11 is located inside the slot 15.
[0026] It should be noted that the motor 12 is connected to an external power supply and control switch, and the insertion end of the bidirectional lead screw 10 forms a rotating connection structure with the inner wall of the second groove 7 through a bearing.
[0027] In practical use, by starting the motor 12, the transmission belt 13 drives it to rotate counterclockwise. At this time, the two threaded connecting blocks 11 connected to the outer wall will drive the two protective covers 14 to move in opposite directions. Meanwhile, the front of the two protective covers 14 will slide along the guide rod 8 under the action of the connecting block 9, so that the two protective covers 14 can be separated.
[0028] Conversely, by starting the motor 12, the transmission belt 13 drives it to rotate clockwise. At this time, the two threaded connecting blocks 11 connected to the outer wall will drive the two protective covers 14 to move towards each other. Meanwhile, the front of the two protective covers 14 will slide along the guide rod 8 under the action of the connecting block 9, so that the two separate protective covers 14 can close towards the center.
[0029] Preferably, the outer walls of both the connecting block 9 and the threaded connecting block 11 are provided with a first slot 16, and the outer walls of both the threaded connecting block 11 are provided with a second slot 21. The bottoms of the two protective covers 14 are connected to a mounting base 17. A spring 18 is provided inside the mounting base 17. A movable block 19 is connected to the end of the spring 18. A locking pin 20 is connected to one end of the movable block 19. One end of the locking pin 20 extends through into the slot 15. The first slot 16 and the second slot 21 are adapted to the slot 15 at one end of the locking pin 20.
[0030] It should be noted that the connecting block 9 can form an elastic engagement structure with the protective cover 14 through the first slot 16, mounting base 17, spring 18, movable block 19, locking pin 20 and slot 15, and the threaded connecting block 11 can also form an elastic engagement structure with the protective cover 14 through the second slot 21, mounting base 17, spring 18, movable block 19, locking pin 20 and slot 15.
[0031] In practical use, the movable block 19 is moved by the lever to retract the locking pin 20. At this time, the locking pin 20 at this position will disengage from the first slot 16 or the second slot 21. Then, by lifting the protective cover 14, the connecting block 9 and the threaded connecting block 11 are disengaged from the slot 15, so that the protective cover 14 can be easily disassembled.
[0032] Conversely, during installation, the movable block 19 is moved by the lever to retract the locking pin 20, and then the tops of the connecting block 9 and the threaded connecting block 11 are respectively inserted into a slot 15. At this time, releasing the lever and locking pin 20 will insert it into the first slot 16 or the second slot 21 under the action of the spring 18, thus completing the installation and fixing of the protective cover 14.
[0033] Working principle: First, by starting the motor 12, the transmission belt 13 drives it to rotate counterclockwise. At this time, the two threaded connecting blocks 11 on its outer wall will drive the two protective covers 14 to move in opposite directions. Simultaneously, the front sides of the two protective covers 14 will slide along the guide rod 8 under the action of the connecting block 9, thereby separating the two protective covers 14. At this time, the operator can insert the LED lamp bead's pin into the detection slot 5. Then, by starting the motor 12, the transmission belt 13 drives it to rotate clockwise. At this time, the two threaded connecting blocks 11 on its outer wall will drive the two protective covers 14 to move in opposite directions. The cover 14 moves towards each other to close, and a stable voltage is supplied to the LED beads in each detection slot 5 through the power supply box 2. During this period, the staff can check the working status of the LED beads after power-on through the transparent window on the top of the protective cover 14, and reject defective products to achieve quality inspection. The movable block 19 is moved by the toggle block to drive the locking pin 20 to retract. At this time, the locking pin 20 at this position will disengage from the first locking slot 16 or the second locking slot 21. Then, by lifting the protective cover 14, the connecting block 9 and the threaded connecting block 11 are disengaged from the slot 15, so that the protective cover 14 can be easily disassembled.
[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
