DETAILED DESCRIPTION

[0032] See also Figure 1-Figure 6 , the present invention provides a technical solution: an LED lamp bead lighting test device, comprising a lamp bead 11, the front and rear side walls of the lamp bead 11 are fixedly connected with pins 12, and a discharge mechanism is included, and the discharge mechanism is used to arrange a large number of lamp beads 11 neatly;

[0033] A detection mechanism, wherein the discharge mechanism enables the arranged lamp beads 11 to pass through the detection mechanism in sequence; the detection mechanism is used to energize the pins 12 of the arranged lamp beads 11 and screen out the lamp beads 11 that cannot be lit;

[0034] The unloading mechanism 13 is used to transport the qualified lamp beads 11 out of the equipment.

[0035] A large number of lamp beads 11 are neatly arranged through the discharge mechanism and transferred to the detection mechanism in sequence, and then the detection mechanism automatically energizes the two pins 12 of each lamp bead 11. Then the detection mechanism discharges the lamp beads 11 that cannot be used normally after energization from the equipment, and continues to transfer the remaining lamp beads 11 that have passed the inspection to the unloading mechanism 13, and the qualified lamp beads 11 are transferred out of the equipment through the unloading mechanism 13.

[0036] The present invention arranges the lamp beads 11 neatly through the discharging mechanism and transfers them to the detection mechanism in sequence for automatic detection and screening, making the entire screening process more coherent and efficient. Compared with traditional detection methods, the device can effectively reduce human labor and greatly improve detection efficiency and detection effectiveness.

[0037] Furthermore, the discharge mechanism includes a supporting mechanism 21, a vibration disk 22 is arranged on the left side of the supporting mechanism 21, a first track 23 is arranged horizontally on the upper end of the supporting mechanism 21, and the front and rear inner walls of the first track 23 are provided with sliding grooves 24 for accommodating the pins 12. The left end of the first track 23 is connected to the discharge port of the vibration disk 22, and the lamp bead 11 can be slidably arranged on the first track 23; the detection mechanism is arranged on the right side of the first track 23.

[0038] A large number of lamp beads 11 are placed into the vibration plate 22, and the lamp beads 11 are neatly arranged and transferred to the first track 23 through the vibration plate 22, so that the lamp beads 11 are slidably set on the first track 23, wherein the pins 12 on the front and rear sides of the lamp beads 11 are respectively inserted into the slide grooves 24 on the front and rear inner walls of the first track 23, so as to limit the sliding process of the lamp beads 11 in the first track 23 (the sliding of the lamp beads 11 in the first track 23 is that the vibration plate 22 continuously transfers the lamp beads 11 to the first track 23, so that the lamp beads 11 are pushed to the right by the subsequent lamp beads 11 to complete the sliding; in actual use, in order to make the lamp beads 11 slide more smoothly in the first track 23, a linear vibrator can be set at the lower end of the first track 23 according to actual conditions to ensure that the lamp beads 11 can be smoothly transferred in the first track 23), and then the lamp beads 11 in the first track 23 are arranged and sequentially enter the detection mechanism for detection and screening process.

[0039] Furthermore, the detection mechanism includes a first conveyor belt 31 symmetrically arranged in front and back relative to the lateral position of the first track 23, and also includes a second conveyor belt 32 symmetrically arranged in front and back relative to the lateral position of the first track 23, the lower straight section of the first conveyor belt 31 is located above the pin 12, and the upper straight section of the second conveyor belt 32 is located below the pin 12, and the first conveyor belt 31 is provided with a plurality of brushes 33 arranged in an array along the track of the first conveyor belt 31 on one side close to the first track 23, and the second conveyor belt 32 is provided with a plurality of connection blocks 33 arranged in an array along the track of the second conveyor belt 32 on one side close to the first track 23. 5, the connecting blocks 35 are longitudinally elastically slidably connected with the supporting blocks 34, the supporting blocks 34 located on the straight section of the second conveyor belt 32 together form a platform for supporting the lower end surface of the pin 12, the brush 33 located on the straight section of the first conveyor belt 31 is used to contact the upper end surface of the pin 12 and energize the pin 12, the first conveyor belt 31 and the second conveyor belt 32 are provided with a control mechanism; the control mechanism controls the supporting blocks 34 to slide to the side away from the first track 23, so that the lamp beads 11 that cannot be normally energized fall off the equipment; the unloading mechanism 13 is arranged on the right side of the first conveyor belt 31 and the second conveyor belt 32.

[0040] The lamp bead 11 on the first track 23 moves to the right between the first conveyor belt 31 and the second conveyor belt 32, so that the support block 34 on the first conveyor belt 31 and the second conveyor belt 32 cooperates with the brush 33 to clamp the pin 12 together, and then the first conveyor belt 31 and the second conveyor belt 32 drive the lamp bead 11 to move to the right into the unloading mechanism 13 by clamping the pin 12; in this process, the brush 33 contacts the upper end surface of the pin 12 and energizes the pin 12, so that the lamp bead 11 lights up. If the lamp bead 11 cannot light up, correspondingly, the brush 33 in contact with the lamp bead 11 cannot be energized normally. At this time, the control mechanism controls the support block 34 under the brush 33 that cannot be energized normally to slide to the side away from the first track 23, so that the lamp bead 11 that cannot be energized normally falls off the device. Further, the lamp bead 11 that can be energized normally moves to the right under the drive of the first conveyor belt 31 and the second conveyor belt 32 into the unloading mechanism 13, and then leaves the device.

[0041] The present invention drives the lamp bead 11 to move rightward into the unloading mechanism 13 by clamping the pin 12 with the first conveyor belt 31 and the second conveyor belt 32, and energizes the pin 12 during the movement, so that the lamp bead 11 that cannot be lit falls off the equipment, and the lamp bead 11 that can be normally energized enters the unloading mechanism 13 and leaves the equipment; thereby making the entire detection process more consistent and effectively improving the efficiency of the entire detection process.

[0042] Furthermore, hinge blocks 4 are provided at positions corresponding to the brushes 33 on one side of the first conveyor belt 31 , and the brushes 33 are elastically rotatably connected to the corresponding hinge blocks 4 .

[0043] Furthermore, the right ends of the front and rear side walls of the first track 23 are fixedly connected with arc blocks 5. When the brush 33 passes through the arc block 5, it can flip along the upper arc surface of the arc block 5 toward the inner side of the first conveyor belt 31.

[0044] Furthermore, the spacing of the brushes 33 located in the straight section of the first conveyor belt 31 is less than or equal to the width of the pin 12, the first conveyor belt 31 and the second conveyor belt 32 rotate synchronously, the brushes 33 correspond to the support blocks 34 one by one and are close to each other between the first conveyor belt 31 and the second conveyor belt 32, and the brushes 33 located in the lower straight section of the first conveyor belt 31 are located at the lateral midline of the corresponding support block 34.

[0045] Furthermore, the control mechanism includes a plurality of motors 61 respectively fixedly connected to the arc blocks 5, the motors 61 are fixedly connected to the corresponding side walls of the first conveyor belt 31, the arc blocks 5 are vertically fixedly connected to the ends of the outer sides of the first conveyor belt 31 with elastic telescopic rods 62, the ends of the elastic telescopic rods 62 are fixedly connected to clamping blocks 63, the ends of the support blocks 34 are horizontally provided with clamping grooves 64 at the ends of the outer sides of the second conveyor belt 32, and the clamping blocks 63 located in the lower straight section of the first conveyor belt 31 can be clamped into the clamping grooves 64 located in the upper straight section of the second conveyor belt 32.

[0046] As the first conveyor belt 31 and the second conveyor belt 32 rotate, the brushes 33 and the support blocks 34 on the first conveyor belt 31 and the second conveyor belt 32 move closer between the first conveyor belt 31 and the second conveyor belt 32, and then the brushes 33 and the support blocks 34 that move closer to each other clamp the pin 12 of a lamp bead 11 and move to the right. In the process of the brush 33 moving closer to the support block 34, the brush 33 first passes through the arc block 5, so that the brush 33 rotates toward the inside of the first conveyor belt 31 under the limiting action of the arc block 5. Further, in the process of the brush 33 moving closer to the support block 34, there is enough space between the brush 33 and the support block 34 to accommodate the pin 12 to enter, thereby further preventing the lamp bead 11 from moving between the first conveyor belt 31 and the second conveyor belt 32. The lamp bead 11 will be blocked by the brush 33, causing the lamp bead 11 to detach from the equipment; then, as the lamp bead 11 moves to the right along with the first conveyor belt 31 and the second conveyor belt 32, the brushes 33 that are not normally energized will control the corresponding motor 61 to drive the corresponding hinge block 4 to move away from the lamp bead 11, and at the same time, the hinge block 4 drives the corresponding support block 34 to move away from the lamp bead 11 through the clamping block 63. This means that if the lamp bead 11 cannot be energized normally, the support block 34 at the pin 12 on the side wall of the lamp bead 11 will detach from the pin 12, leaving the lamp bead 11 without support and falling freely from the equipment under the action of gravity (since the spacing between the brushes 33 is less than or equal to the width of the pin 12, each pin 12 can be clamped by a brush 33 and a support block 34).

[0047] The present invention controls the support block 34 supporting the lamp bead 11 by turning the brush 33 on and off to cancel the support for the lamp bead 11, so that the device can complete the screening of the lamp bead 11 that cannot be powered on normally, further ensuring the screening accuracy of the lamp bead 11 that cannot be powered on normally, and effectively improving the stability of the device.

[0048] Furthermore, a baffle 7 is provided between the first conveyor belt 31 and the second conveyor belt 32 at the end of the pin 12 , and the baffle 7 is fixedly connected to the right end of the first track 23 , and the baffle 7 is used to prevent the pin 12 from moving longitudinally.

[0049] When the brushes 33 and the support block 34 at the upper and lower ends of the pin 12 move longitudinally and detach from the pin 12, the pin 12 has a tendency to move longitudinally under the clamping of the brushes 33 and the support block 34. At this time, due to the obstruction of the baffle 7, the pin 12 cannot move longitudinally, so that the pin 12 can smoothly detach from the clamping of the brush 33 and the support block 34, and then the lamp bead 11 that cannot be lit can smoothly fall freely and detach from the equipment.

[0051] S1, a large number of lamp beads 11 are neatly arranged through a discharging mechanism and transported to a detection mechanism in sequence;

[0052] S2, then the detection mechanism automatically energizes the two pins 12 of each lamp bead 11;

[0053] S3, the detection mechanism then removes the lamp beads 11 that fail to function normally after power-on from the device;

[0054] S4. Finally, the remaining qualified lamp beads 11 are continuously transported to the unloading mechanism 13, and the qualified lamp beads 11 are transported out of the equipment through the unloading mechanism 13.
