The utility model relates to a long connecting rod feeding device which comprises a material rail 100, a transfer mechanism 200 and a material taking mechanism 300.

As shown in fig. 1 and 3, the long link work 500 is placed on the stock rail 100 in an upright state to be transported one by one. The bent end 530 of the long link is located downward inside the stock rail 100, and the other end is located upward outside the stock rail 100. The material rail 100 is preferably a vibrating material rail 100, and the material rail 100 is slightly inclined, so that the long-link workpiece 500 is vibrated and conveyed from the feeding end to the discharging end by vibration. The long link workpieces 500 may be manually placed into the material rail 100 one by one, or the material rail 100 may have a feeding end connected to the vibration plate 400 matched with the feeding end. The long-link workpieces 500 are stacked in the vibration plate 400, and the long-link workpieces 500 are directionally conveyed to the material rail 100 one by one under the vibration action of the vibration plate 400. The transfer mechanism 200 is connected to the discharge end of the material rail 100. The transfer mechanism 200 includes a fixed base 210 and a turnover base 220. In this embodiment, the turnover seat 220 and the fixing seat 210 are disposed in front-back opposite to each other. The fixing base 210 is fixed in a vertical state, the overturning seat 220 overturns a rotation fulcrum at the bottom of the overturning seat, and the upper part of the overturning seat 220 can reciprocally overturn from the rear upper part to the front lower part relative to the fixing base 210. As shown in fig. 4, the state that the turning base 220 is turned upwards to be relatively parallel to the fixing base 210 is defined as a turned-up state; as shown in fig. 5, the state that the flip seat 220 is flipped down to be relatively perpendicular to the fixing seat 210 is defined as a flipped down state. When the turning seat 220 is in the upturned state, a profiling cavity 230 is formed between the turning seat 220 and the fixed seat 210, and the profiling cavity 230 is similar to the shape of the long connecting rod workpiece 500 in the vertical state. The long link workpiece 500 vibrates from the discharge end of the stock rail 100 into the profiling cavity 230, and the long link workpiece 500 remains in a vertically placed state. Because the profile cavity 230 is shaped like the long link workpiece 500, the long link workpiece 500 is suspended in the profile cavity 230 by its beveled arm 520, thereby ensuring that the long link workpiece 500 does not disengage downwardly from the profile cavity 230 when the flip-up stand 220 is in the flipped-up state. When a long link workpiece 500 enters the profiling cavity 230, the turning base 220 is turned from the up-turned state to the down-turned state, and in the down-turned process, the long link workpiece 500 turns downward along with the turning base 220 until the turning base 220 turns to a horizontal orientation. The reclaimer mechanism 300 includes a movable base 310 and suction heads 320, two suction heads 320 are mounted on the movable base 310, the suction heads 320 are preferably vacuum suction heads 320, and the suction heads 320 are connected with an external vacuum pump. The two suction heads 320 are disposed in a front-to-rear and staggered up and down. In this embodiment, according to the position of the long link workpiece 500 when it is placed horizontally along with the turning base 220, the lower ends of the front suction heads 320 are located lower than the lower ends of the rear suction heads 320, and the height difference between the two suction heads 320 is the same as the height difference between the two long arms 510 of the long link workpiece 500. The movable base 310 drives the two suction heads 320 to move horizontally and to lift synchronously. After the turning seat 220 is in the turned-down state, the movable seat 310 is started to move the two suction heads 320 to the upper side of the turning seat 220 to be aligned with the long-link workpiece 500, and then the movable seat 310 is lowered, and the bottoms of the two suction heads 320 are respectively abutted to the two long arms 510 of the long-link workpiece 500. The long link workpiece 500 is sucked up by the suction head 320, and then the translation seat 312 is lifted up, the long link workpiece 500 is taken away from the turning seat 220, and then moved forward, and the die carrier waiting for the lower station receives the long link workpiece 500. Thereby completing the loading operation of the long link workpiece 500.

That is, the rear side of the first rail 110 is opposite to the front side of the second rail 120, the rear side of the first rail 110 is a vertical flat surface, and the front side of the second rail 120 is stepped with a large upper part and a small lower part, thereby forming the first cavity 130 and the second cavity 140. When the long link workpiece 500 enters the stock rail 100, the long arm 510 of the long link workpiece 500 having the bent end 530 is located in the first cavity 130, the bent end 530 is located in the second cavity 140, and the width of the second cavity 140 is slightly larger than the dislocation width of the bent end 530 and the corresponding long arm 510. The inclined arm 520 of the long link work 500 is located outside the upper portion of the first chamber 130 and is inclined toward the front and upper side, and a long arm 510 of the long link work 500 is located right above the first rail 110. When the long-link workpiece 500 is conveyed on the material rail 100 in a vibrating way, the lower half part of the long-link workpiece 500 is limited back and forth through the cooperation of the first cavity 130 and the second cavity 140; the inclined arm 520 of the long-link workpiece 500 is clamped below the first cavity 130 through the matching of the bending end 530 and the inclined arm, so that the long-link workpiece 500 is limited up and down, and the long-link workpiece 500 is positioned and conveyed. The profiling cavity 230 is located at the discharge end of the first cavity 130 and the second cavity 140, and the profiling cavity 230 is matched to avoid the reverse feeding of the two ends of the long connecting rod workpiece 500.
