[0049] 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. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0051] See also Figure 1-11 , the embodiment provided by the present invention: Example 1

[0052] like Figure 1 and Figure 2 As shown, an automatic detection device for testing lamp beads of LED light strips comprises a workbench 1, a feeding device 2 for installing a light strip reel is installed on one side of the top surface of the workbench 1, a receiving device 3 for winding up the light strip reel is installed on the other side of the top surface of the workbench 1, the LED light strip 5 with inspection is fed out by the feeding device 2, and the inspected light strip is rewound again by the receiving device 3, a lamp bead detection bin 4 for detecting the LED light strip 5 is fixedly installed on the top surface of the workbench 1 and between the feeding device 2 and the receiving device 3, and during the process of feeding and retracting the LED light strip 5, the lamp beads on the LED light strip 5 are inspected and processed by the lamp bead detection bin 4.

[0053] like Figure 4 As shown, the interior of the lamp bead detection chamber 4 is divided into a dust removal area 7 and a detection area 6 by a partition 8. The side walls of the lamp bead detection chamber 4 are penetrated with through grooves for the LED light strip 5 to pass through. The LED light strip 5 is released from the unloading device 2, and passes through the through groove on one side of the lamp bead detection chamber 4 and passes through the other side of the lamp bead detection chamber 4, and is rewound by the receiving device 3 again, so as to detect the quality of the lamp beads on the LED light strip 5 passing through the detection area 6;

[0054] Among them, Figures 7 to 11As shown, the detection area 6 includes a belt pressing assembly 62 and a detection assembly 63. The detection assembly 63 is fixedly installed on the bottom surface of the detection area 6, and the belt pressing assembly 62 is installed on the bottom surface of the detection area 6 on one side of the detection assembly 63. The LED light strip 5 is brought close to and attached to the detection assembly 63 through the belt pressing assembly 62, and it is ensured that the lamp beads on the LED light strip 5 can be close to the detection assembly 63. The detection assembly 63 includes a detection table 631, a limiting table 632, a groove 633, a second rotating rod 634, a second conveying belt 635, a base 636, a photosensitive element 637, and a conductive terminal 638. Limiting tables 632 are fixedly installed on both sides of the detection table 631 respectively. Grooves 633 are respectively formed on the top surfaces of the limiting tables 632. A plurality of second rotating rods 634 are rotatably connected inside the grooves 633. The side walls of the second rotating rods 634 at both ends of the limiting table 632 are sleeved with the second conveying belt 635. A base 636 is fixedly installed at the center of the top surface of the detection table 631. A photosensitive element 637 is provided on the top surface of the base 636. Conductive terminals 638 are respectively encapsulated on the detection table 631 on both sides of the base 636. The top surfaces of the conductive terminals 638 are slidably connected to the power supply contacts on both sides of the lamp beads of the LED light strip 5. The side wall of the conductive terminal 638 is set as an inwardly concave arc portion 639, and a notch 6310 is formed inside the conductive terminal 638. A chute 6311 is formed on the top surface of the conductive terminal 638. Steel balls 6312 are respectively rotatably connected in the chute 6311. The steel balls 6312 are slidably connected to the power supply contacts on both sides of the lamp beads of the LED light strip 5.

[0055] The LED light strip 5 moves on the detection table 631 along with the feeding and discharging of the feeding device 2 and the discharging device 3. Under the pressing of the belt pressing assembly 62, both sides of the LED light strip 5 are driven on the second conveying belt 635, and at the same time, the top surface of the conductive terminal 638 contacts and slides on the power supply contacts on both sides of the lamp beads of the LED light strip 5 through the steel balls 6312. Since the lamp beads of the LED light strip 5 are arranged at equal intervals on the LED light strip 5, when the conductive terminal 638 passes through the power supply contacts on both sides of the lamp beads, power is supplied to a single lamp bead, causing the lamp bead to emit light. The lit lamp bead is detected by the photosensitive element 637 between the two conductive terminals 638. If the photosensitive element 637 detects that the lamp bead emits light, it can be determined that the lamp bead at this position on the LED light strip 5 is not damaged. The same detection is performed on each passing lamp bead to determine whether there are damaged lamp beads on the LED light strip after production.

[0056] As Figure 8 and Figure 9As shown in the figure, the belt pressing assembly 62 includes a downward pressing mechanism and a rolling mechanism. The rolling mechanism is fixedly installed on the side wall of the downward pressing mechanism. The downward pressing mechanism includes a cylinder 621, a moving plate 622 and a movable plate 623. The telescopic shaft ends of the cylinder 621 are respectively fixedly installed at both ends of the bottom surface of the moving plate 622. The cylinder 621 is fixedly installed on the bottom surface of the detection area 6 and is located on one side of the detection assembly 63. Slide columns 624 are respectively fixedly connected to both sides of the bottom surface of the moving plate 622. The movable plate 623 is provided with slide holes corresponding to the positions of the slide columns 624. The slide columns 624 are slidably connected in the slide holes. A limit disk 626 is fixedly connected to the top surface of the slide columns 624. A spring 625 is sleeved on the side wall of the slide columns 624 between the top surfaces of the limit disk 626 and the movable plate 623. The rolling mechanism includes a first rotating rod 627 and a first conveying pressing belt 628. A plurality of first rotating rods 627 are respectively fixedly installed on the side wall of the movable plate 623 through bearing seats. The first conveying pressing belt 628 is sleeved on the plurality of first rotating rods 627. The two sides of the bottom surface of the first conveying pressing belt 628 are in double-sided contact with the two sides of the LED light strip 5 on the top surface of the second conveying pressing belt 635.

[0057] In order to enable the LED light strip 5 to pass through the detection table 631 smoothly, the cylinder 621 is driven to move the moving plate 622 downward, and the LED light strip 5 is pressed downward. At the same time, the spring 625 can also enable the first conveying pressing belt 628 to have a certain buffering effect, so as to prevent the LED light strip 5 from being pulled and damaged during the process of winding and unwinding the LED light strip 5. When the cylinder 621 drives the moving plate 622 to move downward, the first conveying pressing belt 628 also moves downward at the same time, and fits the two sides of the LED light strip 5 with the second conveying pressing belt 635. With the winding and unwinding movement, the first conveying pressing belt 628 and the second conveying pressing belt 635 respectively roll on the movable plate 623 and the limit table 632 to smooth the LED light strip 5, so as to prevent the LED light strip 5 from bending when detecting the lamp beads, so as to ensure that the conductive terminal 638 can slide accurately on the contacts for supplying power to the lamp beads on the LED light strip 5. Embodiment 2

[0058] As Figure 5 and Figure 6 shown, on the basis of Embodiment 1, in order to ensure the conductivity between the conductive terminal 638 and the contacts for supplying power to the lamp beads on the LED light strip 5.

[0059] The dust removal area 7 includes a tape guiding mechanism and a dust removal mechanism. The dust removal mechanism includes an air inlet pipe 71, an air nozzle 72, and an air outlet pipe 73. One side wall of the lamp bead detection bin 4 in the dust removal area 7 is fixedly installed with the air inlet pipe 71, and the other side wall of the lamp bead detection bin 4 in the dust removal area 7 is fixedly installed with the air outlet pipe 73. The inner side wall of the dust removal area 7 where the air inlet pipe 71 is installed is provided with the air nozzle 72. The air nozzle 72 is in the shape of a "duck bill". A gas pump provides gas for the air inlet pipe 71. The gas passes through the air inlet pipe 71 and is blown out from the air nozzle 72. The blown gas blows the floating dust on the contacts that supply power to the lamp beads of the LED light strip 5. The gas with dust is collected and processed again through the air outlet pipe 73, so as to ensure good electrical conductivity between the conductive terminal 638 and the contacts that supply power to the lamp beads on the LED light strip 5.

[0060] In addition, the tape guiding mechanism includes a material guiding frame 74, a support plate 75, and a sliding cylinder 76. The two side walls of the dust removal area 7 located at the through groove position of the lamp bead detection bin 4 are respectively fixedly connected with the material guiding frame 74. The two sides inside the material guiding frame 74 are respectively fixedly installed with the support plate 75. The support plates 75 are symmetrically arranged on the top surface and the bottom surface inside the material guiding frame 74. The top surface of the support plate 75 is provided with a notch. The rotating shafts at both ends of the sliding cylinder 76 are rotatably connected in the notch. The sliding cylinder 76 rotates through the support plate 75 in the material guiding frame 74, so as to smooth the LED light strip 5 passing through the dust removal area 7 and perform preliminary arrangement on the LED light strip 5 entering the detection area 6 to ensure the smooth movement of the LED light strip 5. On both sides of the detection area 6 located at the position of the material guiding frame 74, material openings 61 for the LED light strip 5 to pass through are respectively opened. The material openings 61 are in the shape of a rounded waist. After the LED light strip 5 is smoothed by the sliding cylinder 76 rotating through the support plate 75 in the material guiding frame 74, it enters the detection area 6 through the material opening 61, and then passes through the material opening 61 and exits from the detection area 6, and is wound up again by the material collecting device 3. Embodiment 3

[0061] Such as Figure 2 and Figure 3As shown in the figure, on the basis of Embodiment 1 and Embodiment 2, in order to be able to wind and unwind the LED strip 5, the unwinding device 2 includes a first bracket 21 and an unwinding reel 22. The clamping post on the top side wall of the first bracket 21 is clamped inside the unwinding reel 22. The clamping post is rotatably connected to the first bracket 21 through a bearing. The LED strip 5 to be detected is wound inside the unwinding reel 22. A guiding assembly 9 is fixedly installed on the side wall of the first bracket 21 located in the lamp bead detection bin 4. The winding device 3 includes a second bracket 31 and a winding reel 32. The clamping post on one side of the top of the second bracket 31 is clamped inside the winding reel 32. The clamping post is rotatably connected to the second bracket 31 through a bearing. A driving motor 33 is fixedly installed on the other side of the top of the second bracket 31. The output shaft of the driving motor 33 is fixedly installed with the shaft rod of the clamping post. A guiding assembly 9 is fixedly installed on the side wall of the second bracket 31 located in the lamp bead detection bin 4. The guiding assembly 9 includes a cross plate 91, an oval waist slot 92 and a guiding roller 93. An oval waist slot 92 is opened on the side wall of the cross plate 91. The shaft rod of the guiding roller 93 passes through the oval waist slot 92 and the end is threadedly connected through a nut.

[0062] When it is necessary to detect the lamp beads on the produced LED strip 5, the unwinding reel 22 of the LED strip 5 to be detected is installed on the rotatable clamping post of the first bracket 21. Then, open the lamp bead detection bin 4, thread the LED strip 5 through the material inlet 61 and the guiding frame, then wind it from the bottom surface of the first conveying pressure belt 628, and finally pass through and wind it on the winding reel 32. Drive the rotation of the winding reel 32 through the driving motor 33 on the winding reel 32, which will cause the LED strip 5 to move in the lamp bead detection bin 4. At the same time, guide the LED strip 5 through the guiding assembly 9. Before the LED strip 5 released or wound from the unwinding reel 22 or the winding reel 32 passes through the lamp bead detection bin 4, the LED strip 5 is wound around the guiding roller 93, and the conveying direction of the LED strip 5 is changed through the guiding roller 93, so that the LED lamp can better enter the lamp bead detection bin 4 for detection processing. At the same time, the guiding roller 93 can slide on the oval waist slot 92 by loosening the nut, so as to change the direction of the LED strip 5 entering and exiting the lamp bead detection bin 4 during detection.

[0063] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
