Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of track limit-type drop suction nozzle motion structure of LED automatic placement machine, comprising: mounting panel 1; First belt pulley 2, is pivotably mounted on mounting panel 1; Second belt pulley 6, is pivotably mounted on mounting panel 1, and the first belt pulley 2 and the second belt pulley 6 are provided with belt 7; Motion guide portion 3, is arranged on mounting panel 1, motion guide portion 3 is formed with track groove 4; Component suction nozzle 5, comprises guide part and arm 14, and the upper end of component suction nozzle 5 is connected with belt 7 pivotly by pin, and guide part is arranged in track groove 4 actively; Guidance set, arm 14 is connected with mounting panel 1 by guidance set; Component suction nozzle 5 under the restriction of guidance set and track groove 4 by the driving reciprocating motion of the first belt pulley 2 or the second belt pulley 6.Due to only under the drive of belt 7, may there is the swing on left and right directions in the motion of component suction nozzle 5, therefore, adopts track groove 4 to reduce or to eliminate this swing, improve the precision of motion.Visible, track groove 4, in component suction nozzle 5 motion process, plays the effect of restriction and guiding.
During work, the first belt pulley 2 drives the second belt pulley 6 by belt 7, thus moves reciprocatingly in the movement locus driving component suction nozzle 5 to limit at guidance set and track groove 4, realizes suction nozzle to the feeding of LED lamp bead, paster action.
Owing to have employed technique scheme, the utility model can realize LED paster, improves the speed of LED chip mounter, reduces the volume of LED chip mounter, reduces the cost of chip mounter, has compact conformation, at a high speed, steadily, impacts little feature.
Preferably, the slide block 13 that guidance set comprises horizontal guide rail 8 and slides along horizontal guide rail 8, slide block 13 is formed with gathering sill, and arm 14 is arranged in gathering sill actively.Like this, can make the motion of component suction nozzle 5 more steadily, accurately by guidance set.
Preferably, track groove 4 comprises vertical slots 9 and deep-slotted chip breaker 10, and the upper end of vertical slots 9 is communicated with one end of deep-slotted chip breaker 10.Preferably, Open Side Down for deep-slotted chip breaker 10.
Preferably, motion guide portion 3 comprises plate body 11, and the side of plate body 11 is vertically provided with multiple installation fixing hole 12, and motion guide portion 3 is arranged on mounting panel 1 by installing fixing hole 12, and track groove 4 is formed on plate body 11.Preferably, track groove 4 be formed in plate body 11 towards on the surface of mounting panel 1 side.
Preferably, component suction nozzle 5 at least partially between mounting panel 1 and motion guide portion 3.
Preferably, horizontal guide rail 8 is positioned at the below of the second belt pulley 6.
The utility model additionally provides a kind of LED automatic placement machine, comprises above-mentioned track limit-type drop suction nozzle motion structure.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
