As shown in fig. 1-2, the automatic aluminum plate feeding machine comprises a positioning table 1, a slide rail 2, a movable supporting plate 3 and a sucker mechanism 4, wherein one side of the positioning table 1 is provided with an opening 5, the other side is provided with a positioning area 6, the positioning area 6 is provided with four edges which are sequentially connected end to end, two connected edges are set as fixed edges 7, the fixed edges 7 are respectively provided with a plurality of fixed positioning pins 8, the other two connected edges are set as movable edges 9, the movable edges 9 are respectively provided with a plurality of movable positioning pins 10, the movable positioning pins 10 are respectively driven by a positioning driving mechanism to move towards the direction vertical to the corresponding movable edges 9, a lifting table 11 is arranged below the opening 5, the lifting table 11 is driven to lift by a lifting driving mechanism, the slide rail 2 comprises a fixed slide rail 12 and a movable slide rail 13, the fixed slide rail 12 is in butt joint with the movable slide rail 13, the movable slide rail 13 is arranged on the lifting table 11, the movable supporting plate 3 moves on a sliding rail, the sucker mechanism 4 comprises a sucker frame 14, a plurality of vacuum suckers 15 arranged downwards are mounted on the sucker frame 14, the sucker frame 14 is slidably mounted on a transverse rail 16, and the sucker frame 14 is driven by a transverse driving mechanism to move back and forth between the upper side of the opening 5 and the upper side of the positioning area 6. The aluminum plates 36 are stacked on the pallet 37, the pallet 37 is transferred to the movable pallet 3 by a forklift or the like, the movable pallet 3 is transferred to the movable slide rails 13, and the elevating platform 11 is raised to a height such that the uppermost aluminum plate 36 is close to the vacuum chuck 15 on the chuck holder 14. The vacuum chuck 15 is activated to suck the uppermost aluminum plate 36 and the elevating table 11 is lowered by a certain height so that the uppermost aluminum plate 36 is separated from the stack of aluminum plates 36. The suction cup carriage 14 then traverses the rail 16 so that the sucked aluminum sheet 36 moves to the positioning area 6. The vacuum chuck 15 lowers the aluminum plate 36. The movable positioning pin 10 moves towards the direction perpendicular to the corresponding movable edge 9, so that the aluminum plate 36 is clamped between the fixed positioning pin 8 and the movable positioning pin 10 to form accurate positioning for a manipulator and the like to grab. The suction cup holder 14 is returned to the opening 5 again, the lifting platform 11 is lifted, and the above steps are repeated to complete the sequential feeding of the aluminum plates 36.

Further, as shown in fig. 3-4, a plurality of strip-shaped movable holes 17 are formed in the positioning table 1 on one side of the movable edge 9, the strip-shaped movable holes 17 are perpendicular to the corresponding movable edge 9, the strip-shaped movable holes 17 correspond to the movable positioning pins 10 one to one, the upper ends of the movable positioning pins 10 penetrate through the corresponding strip-shaped movable holes 17 from bottom to top, the positioning driving mechanism includes two positioning cylinders 18, and the positioning cylinders 18 are fixedly connected to the lower ends of all the movable positioning pins 10 on the same side of the movable edge 9 through a connecting plate 19. When the movable positioning pin 10 moves to the outermost side in the elongated movable hole 17, the area of the area surrounded by the fixed positioning pin 8 and the movable positioning pin 10 is the largest, the aluminum plate 36 is placed into the other end of the elongated movable hole 17, the movable positioning pin 10 moves reversely, the area of the area surrounded by the fixed positioning pin 8 and the movable positioning pin 10 is the smallest, the movable positioning pin 10 pushes the slave aluminum plate 36, the aluminum plate 36 is located at the position limited by the fixed positioning pin 8 and the movable positioning pin 10, and therefore accurate positioning of the aluminum plate 36 is achieved. When the aluminum plate 36 is grasped by the manipulator or the like, the movable positioning pin 10 moves to the other end of the elongated movable hole 17 again, and the manipulator or the like is not influenced to grasp the aluminum plate 36.

Further, the lifting driving mechanism is a lifting cylinder 20 or a lifting motor. The lifting driving mechanism only needs to adopt a conventional driving mode. However, in order to cooperate with the vacuum chuck 15 to suck the aluminum plate 36, it is preferable to use the elevating platform 11 driven by a servo motor, so that the height of the elevating platform 11 can be accurately controlled.

Further, a roller 21 is installed below the movable supporting plate 3, the roller 21 rolls on the sliding rail 2, and a motor for driving the roller 21 to roll is installed on the movable supporting plate 3. The rollers 21 are divided into a front pair and a rear pair, each pair of rollers is connected through a rotating shaft, and the rotating shaft is rotatably arranged on the movable supporting plate 3. One of the rotating shafts is connected with a motor through a gear or a belt.

The quantity of slide rail 2 is two, two slide rail 2 parallel arrangement. Accordingly, the number of the movable slide rails 13 is two, when the movable pallet 3 is transferred to the lifting table 11, the first pair of rollers 21 continues to move after passing through the front communication opening 24, and then contacts the rear pressing rod 27 extending from the rear communication opening 25, and the inclined guide surface 28 on the rear pressing rod 27 contacts the rollers 21 to generate a downward component force, so that the rear pressing rod 27 descends. The corresponding end of the movable lever 29 is pressed down by the rear pressing lever 27 and overcomes the elastic force of the spring 32. The other end of the movable rod 29 is raised to push the telescopic bar 26 out of the front communication port 24, so that the two pairs of rollers 21 on the movable pallet 3 are clamped between the telescopic bar 26 and the baffle 22.

Further, the cross section of the sliding rail 2 is circular, the inclined guide surface 28 is a spherical surface, the circumferential surface of the roller 21 is provided with an annular groove 33, and the annular groove 33 is matched with the sliding rail 2. Therefore, the contact area between the roller 21 and the inclined guide surface 28 is reduced, the friction force between the inclined guide surface 28 and the roller 21 is small, and the problem of jamming is avoided. The rear pressure lever 27 rises to enable the movable supporting plate 3 to incline at a small angle, and the vacuum sucker is not influenced to suck the aluminum plate.

Further, the transverse moving driving mechanism comprises a transverse screw rod 34, the transverse screw rod 34 is rotatably installed on the positioning table 1, and a screw rod pair 35 fixedly connected with the suction cup frame 14 is arranged on the transverse screw rod 34.
