The specific embodiment
Be the effect that describes technology contents of the present invention, structural feature in detail, realizes, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
Such as Fig. 1, Fig. 2 and shown in Figure 3, suction nozzle range adjuster 100 of the present invention can be regulated the distance between the suction nozzle 4, makes it adapt to spacing between each workpiece, thereby effectively workpiece is drawn and shifted.Suction nozzle range adjuster 100 comprises a main support (not shown), a straight line drive unit 1, a drive plate 2, five sliding supports 3, six suction nozzles 4 and a fixed support 5.Main support is fixed, and five sliding supports 3 are arranged side by side and relatively main support slip, and five suction nozzles 4 are individually fixed in the lower end of five sliding supports 3; Drive plate 2 relative main supports slide, and the glide direction of drive plate 2 is vertical with the glide direction of sliding support 3, and the glide direction of sliding support 3 is horizontal direction among the present invention, and the glide direction of drive plate 2 is vertical direction.Drive plate 2 is provided with the inclined-plane drive division corresponding with sliding support 3, and the inclined-plane drive division is skewed slot 21, and the two side of skewed slot is respectively the first inclined-plane 21a and the second inclined-plane 21b, and the first inclined-plane 21a and the second inclined-plane 21b are parallel to each other.Utilize skewed slot 21, each sliding support 3 can draw under the driving of skewed slot 21 or scatter.Each sliding support 3 is provided with sliding part 31, and sliding part 31 is arranged on the first inclined-plane 21a and the second inclined-plane 21b slidably; Linear drive apparatus 1 promotes drive plate 2 and moves, and then orders about sliding part 31 and slide along the first inclined-plane 21a and the second inclined-plane 21b.Fixed support 5 is fixed in main support, and is arranged side by side with sliding support 3, and a suction nozzle 4 is fixed on the fixed support 5.Glide direction that it should be noted that sliding support 3 and the glide direction of drive plate 2 also can be identical or become cross-like, and at this moment, a position that only needs to adjust each skewed slot 21 gets final product.The inclined-plane drive division also can be oblique raised line, and tiltedly raised line protrudes from the outside of drive plate 2, and the two side is the first inclined-plane 21a and the second inclined-plane 21b.
In conjunction with Fig. 1 and Fig. 2, as shown in Figure 3, the slope of skewed slot 21 reduces from left to right gradually.Particularly, fixed support 5 is fixed in a side of main support, sliding support 3 is arranged side by side with main support, the slope of skewed slot 21 is from reducing gradually near a side direction of fixed support 5 side away from fixed support 5, take fixed support 5 as reference, when each sliding support 3 scattered, each sliding support 3 was away from fixed support 5, during gathering near fixed support 5.Owing to utilize the slope variation of skewed slot 21, the length of the projection of sliding part 31 on the glide direction of sliding support 3 is increased gradually, thereby make each sliding support 3 when sliding, can pull open each other distance, reach the purpose of adjusting distance.More specifically, the equal in length of each projection of skewed slot 21 on the glide direction of drive plate 2, the length of each projection of skewed slot 21 on the glide direction of sliding support 3 becomes arithmetic progression.Because each skewed slot 21 is on same drive plate 2, the length of each projection of skewed slot 21 on the glide direction of drive plate 2 is arranged to equate, therefore, each sliding part 31 can be skewed slot 21 interior omnidistance slips under the driving of drive plate 2, and after slip, distance between the sliding support 3 equates, has reached like this purpose that sliding support 3 is mutually equidistant adjusting.At this moment, suction nozzle 4 just can be equidistant arrangement, and then each workpiece that is equidistant arrangement is adsorbed simultaneously, increases work efficiency.
