[0044] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] Reference Figures 1 to 7 As shown, the utility model provides an LED bulk material placement machine, including a placement device, and a bulk material feeding device arranged on one side of the placement device; the bulk material feeding device includes two transfer mechanisms 1, a loading and vibrating mechanism 2 arranged between the two transfer mechanisms 1 and the placement device, and a vibration plate mechanism 3 arranged on opposite sides of the two transfer mechanisms 1; the vibration plate mechanism 3 is used to load materials one by one and identify the direction of the materials; each transfer mechanism 1 is used to transfer materials from a vibration plate mechanism 3 to the loading and vibrating mechanism 2, and the transfer mechanism 1 is also used to adjust the positioning angle of the material according to the identified material direction; the loading and vibrating mechanism 2 is used to transfer the material from the end where the transfer mechanism 1 is located to the end where the placement device is located; the placement device is used to take materials from the loading and vibrating mechanism 2, and after correcting and adjusting the positioning of the materials, mount the materials on the substrate 8.

[0046] The utility model is provided with two transfer mechanisms 1, two vibration plate mechanisms 3 and a feeding and vibrating mechanism 2. The materials of the two vibration plate mechanisms 3 are first transferred to the feeding and vibrating mechanism 2, and the patch equipment then takes the materials from the feeding and vibrating mechanism 2, i.e., double-input and single-output, instead of letting the patch equipment take the materials directly from the vibration plate mechanism 3, thereby improving the material taking efficiency and saving the waiting time. At the same time, when customers paste different types of LED lamp beads, they only need to quickly replace the bulk material feeding equipment, thereby reducing the equipment cost.

[0047] The transfer mechanism 1 includes a swing arm beam 11, a material taking suction nozzle 12 arranged on the swing arm beam 11, a first positioning drive assembly for driving the material taking suction nozzle 12 to adjust and position the material, a first lifting drive member 13 for driving the swing arm beam 11 to lift and lower the material, and a swing drive member 14 for driving the swing arm beam 11 to swing and take the material.

In a specific embodiment, the material picking nozzle 12 is arranged at the first end of the swing arm beam 11, and the loading positioning drive motor 15 is arranged at the second end of the swing arm beam 11. The swing arm beam 11 is provided with a hollow structure, and the transmission belt 16 is arranged in the hollow structure. This structural design provides favorable conditions for the high-speed operation of the swing arm beam 11 (if the loading positioning drive motor 15 is arranged at the first end of the swing arm beam 11, and the swing arm beam 11 has a certain length, it will affect the speed and positioning accuracy of the swing arm beam 11 driving the material picking nozzle 23 to a certain extent).

[0049] The patch equipment includes a conveyor plate mechanism 4, a patch head 5 arranged above the conveyor plate mechanism 4, a camera correction mechanism 6 arranged between the conveyor plate mechanism 4 and the feeding and vibrating mechanism 2, and a patch translation driving mechanism 7 for driving the patch head 5 to translate.

[0050] The conveyor plate mechanism 4 includes two conveyor tracks 41 arranged in parallel, a conveyor belt assembly 42 arranged on the inner side of each conveyor track 41, and a conveyor drive 43 for driving the conveyor belt assembly 42 to move; a width adjustment screw 44 is installed between the two conveyor tracks 41; the width adjustment screw 44 is driven and connected to a width adjustment drive 45, and the width adjustment drive 45 is used to drive the width adjustment screw 44 to adjust the spacing between the two conveyor tracks 41. The opposite sides of the substrate 8 are each conveyed by a conveyor belt assembly 42, and the opposite sides of the substrate 8 are each limited by a conveyor track 41. Specifically, the transmission drive 43 and the width adjustment drive 45 are both motors. By setting the width adjustment drive 45 and the width adjustment screw 44, the conveyor plate mechanism 4 can adapt to substrates 8 of different widths, and has strong versatility.

[0051] The patch head 5 includes an alignment camera 51, a plurality of patch nozzles 52, a plurality of patch rotation driving members 53 corresponding to the plurality of patch nozzles 52, and a second lifting driving member 54 for driving the plurality of patch nozzles 52 to rise and fall. Specifically, the patch rotation driving member 53 and the second lifting driving member 54 are both motors. The camera calibration mechanism 6 includes a calibration camera 61 and a calibration camera light source 62 disposed above the calibration camera 61.

[0052] The patch translation drive mechanism 7 includes an X-axis patch drive component 71 for driving the patch head 5 to move along the X-axis direction, and a Y-axis patch drive component 72 for driving the patch head 5 to move along the Y-axis direction. In a specific embodiment, the X-axis patch drive component 71 is set as one, and the Y-axis patch drive component 72 is set as two, and the two Y-axis patch drive components 72 are arranged in parallel, and the X-axis patch drive component 71 is installed through a crossbeam and the two ends are respectively connected to a Y-axis patch drive component 72. The X-axis patch drive component 71 and the Y-axis patch drive component 72 both include a screw and a drive motor.

[0053] The feeding and vibrating mechanism 2 includes a feeding plate 21, a vibrating waiting plate 22 arranged at the end of the feeding plate 21, and a first vibrator arranged at the bottom of the feeding plate 21; a number of feeding troughs consistent with the number of patch suction nozzles 52 are opened on the top of the feeding plate 21, and a number of waiting troughs corresponding to the number of feeding troughs are opened on the top of the vibrating waiting plate 22; the first vibrator is used to drive the material to move from the feeding trough to the waiting trough.

[0054] The utility model provides a plurality of feeding slots (waiting slots) on the feeding and vibrating mechanism 2, so that the patch device can take a plurality of materials at one time without waiting. When the patch device is mounted at high speed, the feeding and vibrating mechanism 2 with a buffering function always ensures stable feeding.

[0055] When one of the vibration plate mechanisms 3 or one of the transfer mechanisms 1 stops due to a fault, only half of the feeding slots (waiting slots) on the feeding and vibrating mechanism 2 will not be fed. Since the other set of vibration plate mechanisms 3 and the transfer mechanism 1 can continue to work normally, the patch equipment can take materials from the other half of the waiting slots on the feeding and vibrating mechanism 2, and the patch equipment will not stop.

[0056] The vibration plate mechanism 3 includes a vibration plate 31, a linear feed track 32 connected to the discharge port of the vibration plate 31, and a second vibrator 33 arranged at the bottom of the linear feed track 32; a material sensor is installed on the linear feed track 32 for identifying the direction of the material; the second vibrator 33 is used to drive the material on the linear feed track 32 to move from one end of the vibration plate 31 to the other end.

[0057] The working process of the bulk material feeding equipment provided by the utility model is as follows:

[0058] 1) The material (LED lamp beads) is vibrated out in an orderly manner in the vibration plate 31 to the linear feeding track 32, and waits for the transfer mechanism 1 to pick up the material after the material sensor on the linear feeding track 32 identifies the material direction;

[0059] 2) The first lifting drive member 13 and the swing drive member 14 drive the swing arm beam 11 to drive the material picking nozzle 12 to reach the linear feeding track 32 to pick up the material. According to the identified material direction, the feeding positioning drive motor 15 drives the transmission belt 16 to drive the material picking nozzle 12 to rotate to perform the first positioning and adjust the material angle;

[0060] 3) The transfer mechanism 1 transfers the material to the loading trough of the loading and vibrating mechanism 2. Driven by the first vibrator, the material reaches the waiting trough and waits for the patch equipment to pick up the material.

[0061] The working process of the patch equipment provided by the utility model is as follows:

[0062] 1) The substrate 8 enters from the conveyor plate mechanism 4 and stops at the patch position;

[0063] 2) The X-axis patch drive assembly 71 and the Y-axis patch drive assembly 72 drive the patch head 5 to move to the top of the material waiting slot of the feeding and leveling mechanism 2, and the second lifting drive member 54 drives the patch suction nozzle 52 to descend and take the material;

[0064] 3) After picking up the material, the second lifting drive member 54 drives the patch nozzle 52 to rise, the X-axis patch drive component 71 and the Y-axis patch drive component 72 drive the patch head 5 to drive the material to pass the recognition and correction of the camera correction mechanism 6, and the patch rotation drive member 53 drives the corresponding patch nozzle 52 to drive the material to rotate to perform a second positioning and adjust the angle of the material;

[0065] 4) The X-axis patch drive assembly 71 and the Y-axis patch drive assembly 72 drive the patch head 5 to drive the material to the patch position, the alignment camera 51 performs camera positioning, and the second lifting drive member 54 drives the patch nozzle 52 to mount the material on the substrate 8;

[0066] 5) After the patch is completed, the substrate 8 flows out on the conveyor plate mechanism 4.
