In the existing feeding link, the mainstream feeding device mainly includes a combination of a vibrating feeder and a vacuum nozzle, a material belt type feeder, etc. Among them, the combination of the vibrating feeder and the vacuum nozzle is the widely used automatic feeding mode at present: the vibrating feeder first sorts and orients the bulk lamp beads, so that the lamp beads are output to the designated station in a unified posture; then the vacuum nozzle takes the lamp beads one by one through negative pressure, moves to the corresponding welding position of the lamp tray and releases them. The material belt type feeder embeds the lamp beads in the fixed clamping groove of the continuous material belt in advance, and then moves the lamp beads to the welding station through the step-by-step movement of the material belt, and then transfers them to the lamp tray by a mechanical arm or a special material taking mechanism.

[0003] The existing feeding process of LED lamp beads mainly adopts a single material taking and feeding mode one by one, lacks the structure design of alternating and continuous feeding of lamp beads, and causes obvious intermittent waiting period in the feeding process, so that batch lamp beads cannot be fed synchronously, the welding station needs to wait for the completion of feeding frequently, and the overall production rhythm is slowed down. In addition, the adaptability to different specifications of the lamp tray is poor, the position and number of the feeding unit of the existing device are usually fixed, and cannot be flexibly adjusted according to the number and shape of the LED lamp beads distributed on the lamp tray.

The upper surfaces of the two stabilizing rings 64 are each fixedly connected with a stabilizing rod 66, and the tops of the two stabilizing rods 66 are respectively fixedly connected with the lower surfaces of the two rotating tables 62. The two rotating tables 62 are each provided with a group of linear modules one 67, each group of linear modules one 67 is provided with two linear modules one 67, the two linear modules one 67 of each group are fixedly connected with a linear module two 68, and the two linear module twos 68 are each provided with a moving table 69.

[0017] It should be noted that the vibrating distribution tray 2 is an existing device, which is mainly used to adjust the feeding posture of the LED lamp beads, wherein the feeding posture of the LED lamp beads is that the welding feet are downward and the light-emitting surfaces are upward, the feeding frame 3 is used to stabilize the posture of the LED lamp beads during feeding, so that the LED lamp beads can always maintain a fixed posture during feeding. The two rotating tables 62 are symmetrically arranged about the feeding plate 4, the rotating table 62 can provide a movable space for the linear module one 67, the functions of the linear module one 67 and the linear module two 68 are to provide the kinetic energy of linear motion, and the linear module one 67 and the linear module two 68 are existing technologies, which can be linear motors or motor + ball screw structures, the running tracks of the linear module one 67 and the linear module two 68 are perpendicular to each other, the linear module one 67 can drive the linear module two 68 to move linearly after being started, the linear module two 68 can drive the moving table 69 to move linearly, and the moving table 69 can move in four directions of front, back, left and right under the joint action of the linear module one 67 and the linear module two 68, so as to be adjusted to the required position.

[0018] As Figures 2 to 8As shown, the mobile table 69 is provided with a feeding assembly, which comprises a plurality of threaded holes 71 arranged in a linear array on the mobile table 69, two groups of limiting holes 72 arranged in a linear array on the mobile table 69, the two groups of limiting holes 72 being symmetrical about the threaded holes 71, a threaded rod 73 being threadedly connected in the interior of each threaded hole 71, a limiting frame 74 being rotatably connected to the outer surface of each threaded rod 73, the limiting frame 74 being composed of two rotating rings and two cross bars, wherein the two rotating rings of the limiting frame 74 are rotatably connected to the outer surfaces of the two ends of the threaded rod 73, the two cross bars of the limiting frame 74 respectively pass through the two limiting holes 72 symmetrical about the threaded holes 71 and the cross bars of the limiting frame 74 are capable of sliding in the limiting holes 72. The end of each threaded rod 73 is fixedly connected with a knob 75, and the end of each limiting frame 74 away from the knob 75 is inserted with a mounting frame 76. Specifically, the mounting frame 76 is provided with a slot corresponding to the two cross bars of the limiting frame 74, and the cross bars of the limiting frame 74 can be inserted into the slot to realize the insertion of the mounting frame 76 and the limiting frame 74. A feeding frame 78 for accommodating the LED lamp beads falling from the feeding plate 4 is fixedly installed on the side of each mounting frame 76 away from the limiting frame 74, and each feeding frame 78 accommodates one LED lamp bead.

[0019] Preferably, one side of each mounting frame 76 close to the threaded rod 73 is fixedly connected with a magnet 77, the threaded rod 73 is made of steel, and the magnet 77 can be attracted to the threaded rod 73 to keep the mounting frame 76 stable when the mounting frame 76 is inserted on the limiting frame 74.

[0020] Specifically, a large number of LED lamp beads are put into the vibration distribution tray 2 in advance, and the posture of the LED lamp beads is adjusted after the vibration distribution tray 2 is started, so that the LED lamp beads always maintain the same posture during feeding and flow to the discharge port of the vibration distribution tray 2. Under the action of the vibration adjustment of the vibration distribution tray 2, the LED lamp beads are conveyed to the feeding frame 3, and finally the LED lamp beads conveyed to the feeding frame 3 are conveyed to the feeding plate 4. Then the output shaft of the motor 61 rotates, the output shaft of the motor 61 drives the rotating table 62 to rotate, so that the rotating table 62 rotates to the position below the feeding frame 78 close to the feeding plate 4, and then the linear module one 67 and the linear module two 68 are started. The linear module one 67 drives the linear module two 68 to move horizontally, and the linear module two 68 drives the moving table 69 to move horizontally after being started. Through the cooperation of the linear module one 67 and the linear module two 68, the moving table 69 moves horizontally in four directions of front, back, left and right on the horizontal plane, until the movement of the moving table 69 makes the feeding frame 78 that needs to catch the LED lamp beads move to the position directly below the feeding plate 4. The LED lamp beads sliding downward from the feeding plate 4 will fall into the feeding frame 78 below the feeding plate 4. Then the same rotating table 62 is driven by the linear module one 67 and the linear module two 68 to move to the position below the feeding plate 4, thereby realizing the effect of automatically catching the LED lamp beads. When all the feeding frames 78 on the same rotating table 62 complete the catching of the LED lamp beads, the motor 61 below the other rotating table 62 is started to drive the other rotating table 62 to rotate, so that the feeding frame 78 on the other rotating table 62 moves to the position below the feeding plate 4 to catch the LED lamp beads one by one, until all the feeding frames 78 on the other rotating table 62 complete the catching of the LED lamp beads. Through the two rotating tables 62, the two groups of feeding frames 78 are alternately matched and operated, the LED lamp beads that need to be welded are intermittently and continuously caught by the feeding frames 78 on the two rotating tables 62, the feeding efficiency during welding of the LED lamp beads is improved, and after the feeding is completed, the subsequent welding operation can be conveniently carried out. Compared with the existing single LED lamp bead picking and welding mode, the batch welding of the LED lamp beads can be carried out faster, and the welding efficiency of the LED lamp beads is improved.

[0021] It should be noted that, in order to stabilize the rotating movement of the rotating table 62, the stabilizing rod 66 will rotate synchronously with the rotating table 62 during the rotation of the rotating table 62, and the stabilizing ring 64 will rotate in the interior of the stabilizing table 63, and the rolling connection between the stabilizing ring 64 and the stabilizing table 63 during the rotation of the stabilizing ring 64 makes the friction between the stabilizing ring 64 and the stabilizing table 63 small, which is conducive to the smooth rotation of the stabilizing ring 64. The synchronous rotation of the stabilizing rod 66 with the rotating table 62, and the support of the stabilizing ring 64 on the rotating table 62 at all times, can ensure that the rotating table 62 remains stable during rotation, and can ensure that the rotating table 62 can operate smoothly after a long period of operation, and can avoid the problem of inaccurate receiving of LED lamp beads due to the tilting of the rotating table 62 after a long period of operation, and can improve the effect of accurate receiving of LED lamp beads.

[0022] Due to the different number and arrangement positions of LED lamp beads on the lamp panel, the positions and number of the feeding frames 78 can be adjusted. When adjusting the positions of the feeding frames 78, the worker can hold the knob 75 and then rotate the knob 75, and the knob 75 drives the threaded rod 73 to rotate and move horizontally, and the threaded rod 73 drives the limiting frame 74 to move horizontally in the limiting hole 72 during the movement of the threaded rod 73, and the limiting frame 74 drives the mounting frame 76 to move horizontally at the same time, and the mounting frame 76 drives the feeding frame 78 to move horizontally at the same time, so as to adjust the position of the feeding frame 78. In this way, the positions of all the feeding frames 78 are adjusted one by one until all the feeding frames 78 are adjusted to the predetermined positions, so that the arrangement positions of all the feeding frames 78 are the same as the arrangement positions of the LED lamp beads on the lamp panel. When adjusting the number of the feeding frames 78, when the number of LED lamp beads on the lamp panel is small, the number of the feeding frames 78 needs to be reduced accordingly, and at this time, part of the feeding frames 78 can be removed, and the worker can directly pull the mounting frame 76 to make the mounting frame 76 disengage from the limiting frame 74, and at this time, the magnet 77 is no longer magnetically attracted to the threaded rod 73, and the feeding frame 78 can be removed by taking the mounting frame 76 off the limiting frame 74. When the feeding frame 78 needs to be reinstalled, the worker can insert the mounting frame 76 into the limiting frame 74, and then magnetically attract the magnet 77 to the threaded rod 73 to make the mounting frame 76 stably connected to the threaded rod 73, thereby completing the installation of the feeding frame 78. By adjusting the positions and number of the feeding frames 78, the lamp panel with different number and arrangement positions of LED lamp beads can be adapted, the adaptability to different styles of lamp panels can be improved, and the feeding frame 78 can accurately put the LED lamp beads into the specified positions on the lamp panel.

[0023] It should be noted that the above adjustment of the number and position of the feeding frame 78 can be adjusted according to the arrangement of the LED lamp beads, and the feeding frame 78 can be adjusted to a straight arrangement or an arc arrangement or other shapes, which has high flexibility and improves the applicability of the present feeding machine.

[0024] As shown in Figures 1 to 8 Each mounting frame 76 is provided with an air control assembly for controlling the dropping of LED lamp beads, and the air control assembly comprises a flexible clamp 81 fixedly connected to the side of each mounting frame 76 away from the limiting frame 74. The number of the flexible clamps 81 corresponds to the number of the mounting frames 76, and each feeding frame 78 is provided with a flexible clamp 81. The flexible clamp 81 is connected with an air pipe 82, and the top of the moving table 69 is fixedly connected with an air pump 83. The air pump 83 is fixedly connected with the air pipes 82 away from the mounting frames 76. The bottom surface of the feeding frame 78 is open, and the inside of the feeding frame 78 has enough space for the flexible clamp 81 to move.

[0025] It should be noted that when the flexible clamp 81 is inflated, the two clamp arms are opened to the sides, and the space between the two clamp arms allows the LED lamp beads to pass through.

[0026] When the LED lamp beads fall into the inside of the feeding frame 78, the LED lamp beads are located on the top surface of the two clamp arms of the flexible clamp 81 and the LED lamp beads are located in the middle position of the two clamp arms. When all the feeding frames 78 receive the LED lamp beads, the output shaft of the control motor 61 is rotated, the output shaft of the motor 61 drives the rotating table 62 to rotate, and then the rotating table 62 drives the feeding assembly above it to move above the lamp disc to be welded, and then the air pump 83 is started. The air pump 83 will transport gas into the flexible clamp 81 through the air pipe 82. After the flexible clamp 81 is inflated, the clamp arms are opened, and then the LED lamp beads on the top surface of the flexible clamp 81 will continue to fall down. Since the bottom surface of the feeding frame 78 is open, the LED lamp beads will fall down to the lamp disc, achieving the effect of automatic feeding. The above feeding process is carried out after the feeding frame 78 moves above the welding position of the lamp disc, which can ensure the accuracy of the feeding of the LED lamp beads, and can ensure that all the LED lamp beads are fed to the target position at one time, improving the feeding efficiency of the LED lamp beads.

[0027] It should be noted that the position of the lamp disc can be between the two rotating tables 62 and away from the feeding plate 4, and the lamp disc can be kept at the same horizontal height as the rotating table 62. The present feeding machine can cooperate with an external lamp disc welding device to weld the LED lamp beads falling on the lamp disc.

[0028] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
