[0036] An LED lamp bead detection device provided by the present invention includes a conveying device 12, a material separating device 11 and an ejecting device 14 located on both sides of the conveying device 12, a feeding device 13 located on the side of the material separating device 11 away from the conveying device 12, a collecting device 15 located on the side of the ejecting device 14 away from the conveying device 12, and a detection device 16 located above the conveying device 12. The material separating device 11 includes a frame 114, a first conveyor belt 111 arranged in the frame 114, a rotating plate 112 located on one side of the first conveyor belt 111, and a first air cylinder 113 connected to the frame 114 and used to drive the rotating plate 112 to rotate. The conveying device 12 includes runners 121 symmetrically arranged on both sides of the rotating plate 112 for the movement of the LED lamp bead board and a pushing assembly 122 located at one end of the runner 121 and below the feeding device 13.

The pushing assembly 122 is used to push the LED lamp bead board on the runners 121 below the detection device 16 and push the detected LED lamp bead board below the ejecting device 14 to remove unqualified LED lamp beads. The staff places the loading box full of LED lamp bead boards on the feeding device 13. The feeding device 13 moves the LED lamp bead boards in the loading box onto the first conveyor belt 111 of the material separating device 11. The first conveyor belt conveys the LED lamp bead boards to the rotating plate 112. The rotating plate 112 swings left and right through the first air cylinder 113, and the LED lamp bead boards slide onto the runners 121 on both sides of the rotating plate 112 respectively. The pushing assembly 122 is used to push the LED lamp bead boards below the detection device 16, and the detection device 16 detects the LED lamp beads in the LED lamp bead boards.

[0037] Further, the pushing component 122 pushes the LED lamp bead board after detection under the ejecting device 14. The ejecting device 14 moves left and right to eject the unqualified LED lamp beads in the LED lamp bead board and retain the qualified LED lamp beads. The pushing component 122 continues to push the LED lamp bead board and pushes the LED lamp bead board into the material receiving device 15 for recycling. Since there are two runner channels 121, when the rotating plate 112 swings left and right, the LED lamp bead boards can slide onto the runner channels 121 on both sides of the rotating plate 112 respectively. The symmetrically arranged runner channels 121 can detect the LED lamp bead boards on different runner channels 121 simultaneously or alternately, and there is no need for manual removal of unqualified LED lamp beads.

[0041] The detection device 16 includes a first light source 162 and a second light source.

The first light source 162 and the second light source are located on both sides of the LED lamp bead board, and both sides are irradiated simultaneously, so that the detection by the detection camera 161 is more accurate.

[0042] The ejecting device 14 is provided with a slide rail 141 which is located at one end of the runner 121 far from the material distributing device 11 and is arranged horizontally. On the slide rail 141, there is a mounting block 142 which slides horizontally on the slide rail 141. On the mounting block 142, there is a slider 143 which slides vertically on the mounting block 142. On the slider 143, there is a first ejector pin. The mounting block 142 slides horizontally on the slide rail 141. On the one hand, the mounting block 142 moves above different positions of the runner 121. On the other hand, it is convenient for the mounting block 142 to move above the LED lamp beads on the LED lamp bead board, so as to facilitate ejecting the unqualified LED lamp beads in the LED lamp bead board. The slider 143 moves vertically on the mounting block 142, and the first ejector pin is fixed on the slider 143, which is convenient for the first ejector pin to eject the defective LED lamp beads. At the same time, when moving after ejecting the defective LED lamp beads, it will not touch other LED lamp beads.

[0048] Working principle:

[0049] The LED lamp bead board detection device includes a conveying device 12, a material distribution device 11 and an ejecting device 14 located on both sides of the conveying device 12, a loading device 13 located on the side of the material distribution device 11 away from the conveying device 12, a material receiving device 15 located on the side of the ejecting device 14 away from the conveying device 12, and a detection device 16 located above the conveying device 12.

The material distribution device 11 includes a frame 114, a first conveyor belt 111 located inside the frame 114, a rotating plate 112 located on one side of the first conveyor belt 111, alignment components located on both sides of the rotating plate 112, and a first cylinder 113 arranged outside the frame 114 and used to drive the rotating plate 112 to rotate. The alignment components include a second cylinder and a connecting frame. The second cylinder is used to drive the connecting frame to move. The conveying device 12 includes runners 121 arranged at both ends of the rotating plate 112, and a pushing component 122 located on one side of the runners 121. The pushing component 122 includes a guide rail 1221 arranged on one side of the runners 121, first motors and rotating wheels 1223 arranged at both ends of the guide rail 1221, a synchronous belt 1222 located on the first motors and the rotating wheels 1223, a fixing block 1224 slidably connected to the guide rail 1221 and fixed on the synchronous belt 1222, and a hook 1225 located on the fixing block 1224 and with one end extending into the runner 121. A column 163 is arranged on one side of the runner 121.

[0050] The detection device 16 includes a detection camera 161, symmetrically arranged first light sources 162, and symmetrically arranged second light sources. The first light sources 162 are arranged on the frame 114, the second light sources are arranged below the flow channel 121, the detection camera 161 is arranged on the column 163. The ejection device 14 includes a slide rail 141 arranged transversely to the flow channel 121, a mounting block 142 sliding transversely on the slide rail 141, and a slider 143 sliding vertically on the mounting block 142. A first ejector pin is arranged on the slider 143. The material distribution assembly includes a second ejector pin 153 on one side of the flow channel 121, a third ejector pin 154 on the other side of the flow channel 121, a second conveyor belt 155 on one side of the second ejector pin 153, a third conveyor belt 156 on one side of the third ejector pin 154, a first material collection assembly 151 on one side of the second conveyor belt 155, and a second material collection assembly 152 on one side of the third conveyor belt 156.

[0051] The first material collection assembly 151 includes a first support frame 1514, a first material box 1511 arranged obliquely on the first support frame 1514, a first lifter 1512 vertically lifting at the lower end of the first material box 1511, and a first recovery plate 1513 on one side of the first lifter 1512 and below the first material box 1511. The second material collection assembly 152 includes a second support frame 1524, a second material box 1521 arranged obliquely on the second support frame 1524, a second lifter 1523 vertically lifting at the lower end of the second material box 1521, and a second recovery plate 1522 on one side of the second lifter 1523 and below the second material box 1521.

[0052] When detecting the LED lamp bead board, first, install the LED lamp bead board in the feeding box, and place the feeding box with the installed LED lamp bead board in the third material box 132. Since the third material box 132 is arranged in an inclined plane, the feeding box slides down to the third lifter 134. The third lifter 134 descends. When the LED lamp bead board is opposite to the fourth ejector pin 131, the fourth ejector pin 131 ejects, and the LED lamp bead board is ejected onto the first conveyor belt 111 of the material distribution device 11. Further, after the LED lamp bead board is ejected, the third lifter 134 continues to descend until all the LED lamp bead boards in the feeding box are ejected. The third lifter 134 places the empty feeding box on the third recovery plate 133 for recovery. The third lifter 134 continues to rise, and the operation can be repeated with the feeding box filled with LED lamp bead boards.

[0053] Further, after the LED lamp bead board enters the first conveyor belt 111, the first conveyor belt 111 conveys the LED lamp bead board onto the rotating plate 112. The first air cylinder 113 drives the rotating plate 112 to rotate, and the LED lamp bead board slides onto the connecting frames on both sides of the rotation. When the LED lamp bead board slides onto the connecting frame, the second air cylinder drives the connecting frame to move, aligning the LED lamp bead board with the flow channel 121. The first motor rotates, driving the synchronous belt 1222 to rotate. The synchronous belt 1222 drives the fixed block 1224 to move, and the hook 1225 on the fixed block 1224 moves. The hook 1225 drives the LED lamp bead board to move within the flow channel 121. When the LED lamp bead board is located within the detection device 16, the first light source 162 and the second light source irradiate both sides of the LED lamp bead board respectively, and the detection camera 161 detects the lamp beads within the LED lamp bead board. After the detection is completed, the first motor continues to drive the synchronous belt 1222 to rotate. The synchronous belt 1222 drives the fixed block 1224 to move, and the fixed block 1224 drives the hook 1225 to move. The hook 1225 drives the LED lamp bead board to move in the direction of the ejection device 14.

[0054] When the LED lamp bead board is located below the ejection device 14, since the flow channel 121 is symmetrically arranged, the mounting block 142 slides on the slide rail 141, thus facilitating movement above the flow channel 121 at different positions. When the mounting block 142 is located above the set flow channel 121, the slider 143 slides downward, and the unqualified LEDs within the LED lamp bead board are ejected through the first ejector pin. Since the mounting block 142 can slide horizontally on the slide rail 141 and the slider 143 slides vertically on the mounting block 142, the position of the first ejector pin on the LED lamp bead board can be adjusted flexibly, facilitating the ejection of the unqualified LED lamp bead board. Further, since the flow channel 121 is symmetrically arranged, the detection efficiency of the LED lamp bead board can be increased, manual operation can be reduced, and production capacity can be provided.

[0055] Further, after the unqualified LED lamp beads within the LED lamp bead board are ejected, the synchronous belt 1222 moves the LED lamp bead board on one side of the flow channel 121 to the second conveyor belt 155 through the hook 1225. The second conveyor belt 155 adjusts the position of the LED lamp bead board. Further, empty loading boxes are respectively placed on the first material frame 1511 and the second material frame 1521. Since the first material frame 1511 is inclined, the loading box slides onto the first lifter 1512. The first lifter 1512 descends. When the empty loading box is opposite to the LED lamp bead board, the second ejector pin 153 ejects, pushing the LED lamp bead board into the empty loading box until the empty loading box is filled. The first lifter 1512 descends and places the loading box on the first recovery plate 1513. The first lifter continues to rise, and the above steps are repeated.

[0056] Further, when the LED lamp beads move onto the third conveyor belt 156, the third conveyor belt 156 adjusts the position of the LED lamp bead board. Since the second material box 1521 is arranged in an inclined plane, the feeding box slides onto the second lifter 1523, and the second lifter 1523 descends. When the empty feeding box faces the LED lamp bead board, the third ejector pin 154 ejects, pushing the LED lamp bead board into the empty feeding box until the empty feeding box is filled. Then the second lifter 1523 descends and places the feeding box on the second recovery plate 1522, and the second lifter 1523 continues to rise. Repeating the above steps, the first material collection component 151 and the second material collection component 152 cross each other. On the one hand, it can save the volume of the detection equipment. On the other hand, it can improve the efficiency of recycling qualified LED lamp bead boards and increase production capacity.

[0057] The LED lamp bead detection equipment of this preferred embodiment moves the LED lamp bead board to the first conveyor belt through the feeding device. The first conveyor belt moves the LED lamp bead board to the rotating plate, and the rotating plate rotates to slide the LED lamp bead board onto the flow channels respectively. The pushing component pushes the LED lamp bead board to the lower part of the detection device and the lower part of the ejecting device in sequence. After the ejecting device ejects the LED lamp beads in the LED lamp bead board, the pushing component continues to push the LED lamp bead board to the material collection device for recycling, reducing manual operation, accelerating the detection efficiency, and increasing production capacity.

[0058] In summary, although the present invention has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
