[0027] 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; Among them, Figure 7 to Figure 11As shown, the detection area 6 includes a belt pressing component 62 and a detection component 63. The detection component 63 is fixedly installed on the bottom surface of the detection area 6. The belt pressing component 62 is installed on the bottom surface of the detection area 6 located on one side of the detection component 63. The LED light strip 5 and the detection component 63 are brought into close contact through the belt pressing component 62, and it is ensured that the lamp beads on the LED light strip 5 can be close to the detection component 63. The detection component 63 includes a detection platform 631, a limit platform 632, a groove 633, a second rotating rod 634, a second conveying belt pressing 635, a base 636, a photosensitive element 637 and a conductive terminal 638. The limit platforms 632 are fixedly installed on both sides of the detection platform 631, and the top surfaces of the limit platforms 632 are respectively provided with grooves 633, and the interiors of the grooves 633 are rotatably connected with a plurality of first Two rotating rods 634, the side walls of the second rotating rod 634 located at both ends of the limiting platform 632 are sleeved with the second conveying pressing belt 635, a base 636 is fixedly installed at the center of the top surface of the detection platform 631, and a photosensitive element 637 is provided on the top surface of the base 636. Conductive terminals 638 are respectively sealed on the detection platform 631 located on both sides of the base 636. The top surface of the conductive terminal 638 is 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 a concave arc portion 639, and a notch 6310 is opened inside the conductive terminal 638. A slide groove 6311 is opened on the top surface of the conductive terminal 638. Steel balls 6312 are rotatably connected in the slide groove 6311, and 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.

[0028] The LED light strip 5 moves on the inspection table 631 as the discharging device 2 and the receiving device 3 are retracted and released. Under the downward pressure of the belt pressing assembly 62, the two sides of the LED light strip 5 are transmitted on the second conveyor belt pressing belt 635, and the top surface of the conductive terminal 638 also 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 equidistantly arranged on the LED light strip 5, when the conductive terminal 638 passes through the power supply contacts on both sides of the lamp beads, it supplies power to a single lamp bead, causing the lamp bead to emit light. The illuminated 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 is emitting light, it can be determined that the lamp bead at this position on the LED light strip 5 is not damaged. In this way, the same detection is performed on each lamp bead that passes through, thereby determining whether the lamp beads on the LED light strip after production are damaged.

[0029] like Figure 8 and Fig. 9As shown, the belt pressing assembly 62 includes a pressing mechanism and a rolling mechanism. The side wall of the pressing mechanism is fixedly installed with a rolling mechanism. The pressing mechanism includes a cylinder 621, a moving plate 622 and a movable plate 623. The ends of the telescopic shaft of the cylinder 621 are respectively fixedly installed on the two 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. The two sides of the bottom surface of the moving plate 622 are respectively fixedly connected with sliding columns 624. The movable plate 623 is located at the position of the sliding column 624 and has a sliding hole corresponding to the position of the sliding column 624. The sliding column 624 is in the sliding hole. Sliding connection, the top surface of the sliding column 624 is fixedly connected to the limit plate 626, and the side wall of the sliding column 624 between the limit plate 626 and the top surface of the movable plate 623 is sleeved with a spring 625, and the rolling mechanism includes a first rotating rod 627 and a first conveying pressure belt 628, and multiple first rotating rods 627 are respectively fixedly installed on the side walls of the movable plate 623 through bearing seats, and the first conveying pressure belt 628 is sleeved on multiple first rotating rods 627, and the two sides of the bottom surface of the first conveying pressure belt 628 and the top surface of the second conveying pressure belt 635 are in double-sided contact with both sides of the LED light strip 5.

[0030] In order to enable the LED light strip 5 to pass smoothly through the detection table 631, the cylinder 621 drives the movable plate 622 to move downward, and the LED light strip 5 is pressed downward. At the same time, the spring 625 can also make the first conveyor pressure belt 628 have a certain buffering effect to prevent the LED light strip 5 from being pulled and damaged during the process of retracting and releasing the LED light strip 5. When the cylinder 621 drives the movable plate 622 to move downward, the first conveyor pressure belt 628 is also moved downward, and the two sides of the LED light strip 5 are fitted with the second conveyor pressure belt 635. With the retraction and release movement, the first conveyor pressure belt 628 and the second conveyor pressure belt 635 roll on the movable plate 623 and the limit table 632 respectively to flatten the LED light strip 5 to prevent the LED light strip 5 from bending when detecting the lamp beads, so as to ensure that the conductive terminal 638 can accurately slide on the contact point on the LED light strip 5 that supplies power to the lamp beads. Example 2

[0031] like Figure 5 and Figure 6 As shown, on the basis of Example 1, the conductivity between the conductive terminal 638 and the contact point on the LED light strip 5 for supplying power to the lamp beads can be ensured.

[0032] The dust removal area 7 includes a belt guide 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.

The inner side wall of the dust removal area 7 is located at the air inlet pipe 71 and the air nozzle 72 is installed. The air nozzle 72 is "duckbill-shaped". Gas is provided to the air inlet pipe 71 through an air pump, and the gas is blown out from the air nozzle 72 through the air inlet pipe 71. The blown gas blows away the floating dust on the surface of the contacts of the LED light strip 5 that power the lamp beads, and the dusty gas is collected and processed again through the air outlet pipe 73, thereby ensuring good conductivity between the conductive terminal 638 and the contacts on the LED light strip 5 that power the lamp beads.

[0033] In addition, the guide mechanism includes a guide frame 74, a support plate 75 and a slide 76. The side walls of the dust removal area 7 located at the through slot position of the lamp bead detection chamber 4 are respectively fixedly connected with the guide frame 74, and the support plates 75 are respectively fixedly installed on the two sides of the interior of the guide frame 74. The support plates 75 are symmetrically arranged on the top and bottom surfaces of the interior of the guide frame 74. The top surface of the support plate 75 is provided with a notch, and the rotating shafts on the two ends of the slide 76 are rotatably connected in the notch. The slide 76 rotates through the support plate 75 in the guide frame 74, and the dust removal area is passed through. 7 is straightened, and the LED light strip 5 entering the detection area 6 is arranged in advance to ensure the smooth movement of the LED light strip 5. Material openings 61 for the LED light strip 5 to pass through are respectively opened on both sides of the detection area 6 located at the position of the material guide frame 74. The material opening 61 is round and waist-shaped. After the slide cylinder 76 rotates through the support plate 75 in the material guide frame 74 to straighten the LED light strip 5, it enters the detection area 6 through the material opening 61, and then passes through the detection area 6 through the material opening 61, and is rewound again by the receiving device 3.

[0035] When it is necessary to detect the lamp beads on the produced LED light strip 5, the discharge tray 22 on the LED light strip 5 with detection is installed on the rotatable clamping column on the first bracket 21, and then the lamp bead detection chamber 4 is opened, and the LED light strip 5 is inserted from the material port 61 and the guide frame, and then wound from the bottom surface of the first conveyor pressure belt 628, and finally passed out and wound around the receiving tray 32, and the receiving tray 32 is driven by the driving motor 33 on the receiving tray 32 to rotate, so that the LED light strip 5 moves in the lamp bead detection chamber 4, and at the same time, The LED light strip 5 is guided by the guide component 9. The LED light strip 5 released and wound up from the discharge tray 22 or the collection tray 32 is wound around the guide roller 93 before passing through the lamp bead detection bin 4.
