AI Technical Summary
The current warehousing robots are equipped with aligning mechanisms that align multiple layers of goods as a whole, which cannot effectively align the upper goods, causing the goods to tilt and potentially leading to the collapse of the entire pile of goods.
Two parallel push rods are installed on the front face of the secondary gantry of the warehousing robot. The power rocker arm and the follower rocker arm are driven by a servo motor and a dual output shaft reducer through a drive mechanism to extend or retract the push rods, forming a linkage mechanism to straighten the upper goods.
Effectively straighten the upper goods to ensure that the goods are stacked neatly and uniformly, and prevent the goods from collapsing.

[0015] The utility model will be further described in combination with the drawings. These drawings are all simplified schematic diagrams, and only the basic structure of the utility model is schematically shown, so it only shows the structure related to the utility model.
[0016] As Figures 1-3 The utility model discloses a kind of upper righting mechanisms of warehousing goods, it is set in the front end face of secondary portal frame of warehousing robot, and it is used in pairs to right the upper goods that appear to be inclined.
[0017] The secondary portal frame includes a pair of portal columns 1 apart from each other, the upper connecting plate 2 is fixedly connected between the upper ends of the portal column 1, the lower connecting plate 3 is fixedly connected between the lower ends of the portal column 1, two mutually parallel push rods 4 are arranged between the front end faces of the two portal columns 1, and the two push rods 4 are vertically placed and have the same length as the length of the portal column 1.
[0018] The driving mechanism for synchronously extending or synchronously retracting the two push rods 4 to support the goods or to return to the original position is arranged on the rear end face of the two portal columns 1, and the driving mechanism comprises coaxial double-output shaft reducers 7, servo motors 8, a pair of power rocker arms 5 and a pair of follower rocker arms 6, the coaxial double-output shaft reducers 7 are fixed on the rear side of the lower connecting plate 3, and the output end of the servo motor 8 is in transmission connection with the input end of the coaxial double-output shaft reducer 7; shaft seats are respectively arranged on the rear side of the lower connecting plate 3, the two output shafts of the coaxial double-output shaft reducers 7 are extended leftward and rightward, the shaft ends of the two output shafts are rotatably supported on the corresponding shaft seats, the rear ends of the pair of power rocker arms 5 are correspondingly arranged on the two output shafts of the coaxial double-output shaft reducers 7 through the flat keys, and the rear side of the lower connecting plate 3 is provided with long waist holes corresponding to the positions of the power rocker arms 5, and the front ends of the power rocker arms 5 pass through the long waist holes and are movably connected with the lower ends of the push rods 4 through the pin shafts.
