Further, in order to facilitate that the lifting mechanism 300 can timely drive the material bearing platform 200 to ascend when the aluminum plate is out of the telescopic range of the suction cup 411, so as to ensure continuous feeding, the feeding module further comprises a sensor 420 and a controller (not shown), wherein the sensor 420 and the lifting mechanism 300 are both connected with the controller. In this embodiment, the detecting end of the sensor 420 is disposed at the bottom of the feeder taking mechanism 410, and the detecting end is used to abut against the topmost aluminum plate, so as to determine whether the material below the feeder taking mechanism 410 reaches the height position of the detecting end of the sensor 420 when the feeder taking mechanism 410 is located above the preset position, and the fixed end of the sensor 420 extends into the feeder taking mechanism 410. Generally, when the feeder taking mechanism 410 moves to above the aluminum plate to prepare for taking materials, the detecting end of the sensor 420 abuts against the top aluminum plate, when the top aluminum plate is taken for multiple times and is separated from the detecting end of the sensor 420, the sensor 420 sends a signal to the controller, and the controller controls the lifting mechanism 300 to operate according to the signal until the top aluminum plate abuts against the detecting end again; and repeating the feeding process until the feeding is finished.

Further, in order to prevent the adjacent aluminum plates from being sucked together due to vacuum when the aluminum plates are stacked, thereby causing the taking mechanism 400 to take and place a plurality of aluminum plates at a time, the taking mechanism 400 further includes an air blowing pipe 430, and an air blowing device (not shown) connected to the air blowing pipe 430. Specifically, one end of the air blowing pipe 430 is arranged outside the feeder 410 and corresponds to the height position of the detection end of the sensor 420, and the other end of the air blowing pipe 430 is connected to an air blowing device (not shown); the blowing device is used for outputting airflow so that the airflow is output to the edges of the aluminum plates through the blowing pipes, and therefore the adjacent aluminum plates are separated from each other, and the taking and placing process of a single aluminum plate is facilitated. It is worth mentioning that the blowing device and the pneumatic device can be the same device, namely, the blowing device and the pneumatic device are integrated inside the flight material taking mechanism; the blowing device can be independent of the feeder and can blow the blowing pipe 430 independently, and the utility model is not limited in particular.

Referring back to fig. 1 and fig. 2, in conjunction with other figures, the positioning mechanism 500 includes a first positioning plate 510, a second positioning plate 520, and a third positioning plate 530 that are vertically disposed.

The third positioning plate 530 is fixedly mounted on the frame 100 through a horizontally arranged fixing beam 140, and is perpendicular to the direction of the material moving along with the feeding belt 240; along the direction that first locating plate 510 points to second locating plate 520, its at least part of third locating plate 530 is located between first locating plate 510 and second locating plate 520, has between third locating plate 530 and above-mentioned first locating plate 510 or second locating plate 520 and sets for the contained angle, should set for the contained angle specifically to depend on with aluminum plate's profile shape, in this embodiment, aluminum plate wholly is the rectangle profile, third locating plate 530 is all perpendicular with first locating plate 510 and second locating plate 520. It can be understood that, in other embodiments of the present invention, the front edge of the aluminum plate can be inclined at two opposite side edges, and then the third positioning plate, the first positioning plate and the second positioning plate are inclined relatively to adapt to the profile of the aluminum plate, and the set included angle can be any angle between 0 and 180 (excluding the number). When the material supporting platform 200 supports stacked aluminum plates, the first positioning plate 510 and the second positioning plate 520 can move towards a direction close to the center of the material supporting platform 200 at the same time until the gap between the first positioning plate 510 and the second positioning plate 520 is the width of the aluminum plate along the gap direction, two side edges of each stacked aluminum plate are gradually aligned and leveled under the abutting action of the first positioning plate 510 and the second positioning plate 520, meanwhile, the aluminum plate moves to abut against the third positioning plate 530 under the driving of the feeding belt 240, and the front edge of each aluminum plate is gradually aligned and leveled under the abutting action of the third positioning plate 530. In the feeding process, a single aluminum plate can stably rise under the positioning action of the first positioning plate 510, the second positioning plate 520 and the third positioning plate 530 without deflection. It should be noted that the "center of the material platform 200" should be the center of the structure actually carrying the material, since the material is actually carried by the two bases 220 and the two feeding belts 240 in this embodiment, the "center of the material platform 200" in this embodiment is actually the center between the two feeding belts 240.

With reference to fig. 1 and fig. 2, and with reference to fig. 3 to fig. 7, the positioning driving mechanism 600 includes a screw 610, a guide rod 620, and a motor 630. The lead screw 610 is mounted on the frame 100, and the whole lead screw extends in a direction perpendicular to the first positioning plate 510, and two ends of the lead screw 610 are respectively supported on the two side plates 110. The lead screw 610 includes a first portion 611 and a second portion 612, and the first portion 611 and the second portion 612 are opposite in rotation. The first positioning plate 510 is threadedly coupled to a first portion of the lead screw 610, and the second positioning plate 520 is threadedly coupled to a second portion of the lead screw 610. In this embodiment, the first part 611 and the second part 612 are two independent units, and the first part 611 and the second part 612 are coaxially fixed by a connector 613 to realize coaxial rotation; it is understood that in other embodiments of the present invention, the first portion and the second portion may be two portions with opposite thread directions on the same screw rod structure.

The guide rod 620 is installed on the frame 100 and parallel to the lead screw 610, and two ends of the guide rod 620 are respectively supported on the two side plates 110. The guide rod 620 is sleeved with the first positioning plate 510 and the second positioning plate 520, so that the first positioning plate 510 and the second positioning plate 520 are slidably engaged with the frame 100 in a direction parallel to the extending direction of the screw 610. The motor 630 is installed on the frame 100, an output end of the motor 630 is connected to one end of the screw 610, and the motor 630 is used for driving the screw 610 to rotate, so that the first positioning plate 510 and the second positioning plate 520 move towards a direction close to the center of the material holding platform 200, or the first positioning plate 510 and the second positioning plate 520 move towards a direction away from the center of the material holding platform 200. In this embodiment, the motor 630 is indirectly connected to the lead screw 610 through a roller 640 mounted between the two side plates 110 and a timing belt (not shown) wound around the end of the roller 640 and the end of the lead screw 610.

Further, in order to facilitate the stacked aluminum plates to travel on the feeding belt 240 to position the aluminum plates by the third positioning plate 530, the feeding module further includes a material driving mechanism 700, referring to fig. 1 in combination with fig. 2 to 7, the material driving mechanism 700 is connected to the pulley 230, and is configured to drive the pulley 230 to rotate so as to move the feeding belt 240 synchronously, so that each aluminum plate moves from one end away from the third positioning plate 530 to abut against the third positioning plate 530, so as to complete the positioning of each aluminum plate by the third positioning plate 530. In this embodiment, the material drive mechanism 700 includes a first gear 710, a second gear 720, and a handwheel. The first gear 710 is coaxially and fixedly connected with the belt wheel 230 at one end far away from the third positioning plate 530; the second gear 720 is rotatably mounted to the frame 100 and is engaged with the first gear 710; the hand wheel 730 is connected to the second gear 720, so that the worker can rotate the hand wheel 730 to rotate the second gear 720 and the first gear 710 synchronously, so as to rotate the belt wheel 230. The hand wheel 730 may be directly connected to the second gear, or indirectly connected to the second gear through an intermediate transmission device such as a gear set or a bevel gear set.

The operation of the feeding module provided in the above embodiment will be briefly described with reference to the drawings, taking the example that the height of the initially stacked aluminum plate is higher than the detecting end of the sensor 420.

In the initial state, the material supporting platform 200 is located at the bottom of the rack 100, and the first positioning plate 510 and the second positioning plate 520 are respectively located at one end of the first portion 611 and the second portion 612 away from the center of the material supporting platform 200.

When the feeding process needs to be carried out, the stacked aluminum plates are firstly conveyed to the upper part of the feeding belt 240 through an external pre-feeding mechanism, or the stacked aluminum plates are directly stacked on the feeding belt 240. Then, the hand wheel 730 is rotated to make the feeding belt 240 drive the stacked aluminum plates to move to abut against the first positioning plate 510, and then each aluminum plate is positioned in the proceeding direction; meanwhile, the positioning driving mechanism 600 drives the first positioning plate 510 and the second positioning plate 520 to move towards the direction close to the center of the material holding platform 200 at the same time, until the gap between the first positioning plate 510 and the second positioning plate 520 is equal to the width of the aluminum plate along the gap direction, and then each aluminum plate is positioned along the direction perpendicular to the advancing direction.

The material taking mechanism 400 moves to the upper side of the aluminum plate, the detection end of the sensor 420 is abutted to the aluminum plate at the top, the sucker 411 extends downwards to adsorb the aluminum plate, and then the material taking mechanism 400 moves to a specified position to place the aluminum plate so as to complete the taking and placing process of the single aluminum plate. When the material taking process is repeated for a plurality of times until the material taking mechanism is positioned above the aluminum plate and the stacked aluminum plate is separated from the detection end part of the inductor 420, the material taking process is interrupted; at this time, the controller drives the lifting mechanism 300 to move so as to integrally lift the material bearing platform 200 until the top aluminum plate is again abutted to the detection end, and the material taking mechanism 400 continues to take materials. Therefore, the aluminum plates on the material bearing platform 200 are continuously reduced, and the material bearing platform 200 is continuously lifted until all the aluminum plates are loaded.

After the feeding is finished, the first positioning plate 510 and the second positioning plate 520 respectively move to one end far away from the center of the material bearing platform 200 under the driving of the positioning driving mechanism 600; the loading platform 200 is driven by the lifting mechanism 300 to descend to its initial position, and the first gear 710 is engaged with the second gear 720 to wait for the loading process of the next batch of stacked aluminum plates.

The operation of initially stacking aluminum plates at a height lower than the probing end of the sensor 420 is substantially the same as the above-mentioned operation, and is not described herein.
