step 1: pulling the push-pull supporting plate 513 open, loading a plurality of new trays 12 filled with magnetic shoes 13, and pushing the push-pull supporting plate 513 in;

and 2, step: after the push-pull supporting plate 513 is pushed in place, the first detection switch 61 is triggered, the clamping component 52 locks the push-pull supporting plate 513, and the jacking module 11 jacks a plurality of trays 12;

and step 3: when the topmost tray 12 is jacked to the material suction position, the second detection switch 62 is triggered, the material arranging module adjusts the magnetic tiles 13 on the topmost tray 12 in a front-back and left-right mode, then the material suction mechanism 2 starts to suck the magnetic tiles 13 on the topmost tray 12 onto the conveyor belt 4, and the magnetic tiles are conveyed to production lines for detection and the like through the conveyor belt 4;

Further, as shown in fig. 19, in the present embodiment, a stopper 42 and a magnetic shoe detection switch 43 are disposed on the conveyor belt 4, wherein the stopper 42 is disposed at one end far away from the entrance of the conveyor belt 4 (the right end of the conveyor belt 4 in fig. 19 is the entrance of the magnetic shoe), and is configured to be fixedly mounted without moving along with the conveyor belt 4, the magnetic shoe detection switch 43 is disposed at the middle position of the conveyor belt 4, and the distance between the stopper 42 and the detection switch is greater than the length of the M-1 magnetic shoes 13 closely arranged and less than the length of the M magnetic shoes 13 closely arranged, so that when the magnetic shoes 13 are closely arranged to M, the magnetic shoe detection switch 43 is triggered for a long time. Specifically, the magnetic tile detection switch 43 can be selected from but not limited to a photoelectric switch, when the number of the magnetic tiles 13 closely arranged on the conveyor belt 4 is M, the time is triggered, the suction cup assembly 21 in the material suction mechanism 2 starts to correspondingly suck the M magnetic tiles 13 on the conveyor belt 4, and then the magnetic tiles are moved by the displacement module in the material suction mechanism 2 and placed on the empty tray currently located at the material suction position. And the present embodiment lowers the position of the third detection switch 63 as necessary to be triggered when the last tray 12 on the empty tray rack 33 is sucked away.

The working method of the automatic feeding device in the embodiment during material receiving comprises the following steps:

step 1: the recovery mechanism 3 sucks an empty tray from the empty tray frame 33 and places the empty tray on the jacking module 11, at the moment, the jacking module 11 enables the empty tray to be located at a material sucking position at the highest position, the empty tray triggers the second detection switch 62, and the material sucking mechanism 2 waits to work;

step 2: the conveyor belt 4 conveys the magnetic shoes 13 towards the stop block 42 in sequence, the magnetic shoes 13 stop at the current position after being stopped by the stop block 42, when the magnetic shoe detection switch 43 detects that the number of the magnetic shoes 13 closely arranged on the conveyor belt 4 reaches M, the material suction mechanism 2 starts to work, the magnetic shoes 13 on the conveyor belt 4 are sucked and placed on an empty tray at the current material suction position, and the material suction mechanism 2 continues to suck materials when the magnetic shoe detection switch 43 is triggered;

and step 3: after the empty tray at the material sucking position is filled with the magnetic shoes 13, the jacking module 11 descends by the height of the thickness of one tray 12;

and 4, step 4: the recovery mechanism 3 places a new empty tray at the material suction position, and the material suction mechanism 2 continues to suck materials; when the last tray 12 on the empty tray rack 33 is sucked away, the third detection switch 63 is triggered to remind the staff to place a plurality of new empty trays on the empty tray rack 33;

and 5: when the number of the trays 12 on the jacking module 1 reaches a set value, the supporting component 53 clamps the current uppermost tray 12, then the jacking module descends to the lowest position, and the automatic feeding device can send out voice and the like to remind a worker to take away the tray 12 filled with the magnetic tiles 13;

step 6: pulling the push-pull supporting plate 513 open, taking a plurality of trays 12 filled with the magnetic shoes 13 away, and then pushing the push-pull supporting plate 513 in;

and 7: after the push-pull supporting plate 513 is pushed in place, the first detection switch 61 is triggered, the clamping assembly 52 locks the push-pull supporting plate 513, and the jacking module 11 jacks;

and 8: and returning to the step 1 and circularly performing.

Optionally, in other embodiments, the structure of the connection module in the recovery mechanism may also be changed, for example, a clamping jaw structure is used to connect the tray, so that the empty tray may be lifted on the lifting mechanism, and the recovery mechanism is used to clamp the tray full of magnetic tiles after the magnetic tiles on the conveyor belt are placed on the empty tray by the material suction mechanism. Therefore, the material receiving process is similar to the material sending process in the first embodiment, and the difference is that the push-pull supporting plate is filled in the first embodiment to form an empty tray, the material sucking mechanism sucks and places the magnetic tiles on the conveying belt on the empty tray, and the recovery mechanism clamps the tray filled with the magnetic tiles.

Therefore, the automatic feeding device provided by the embodiment can be used for not only sending materials but also receiving materials.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
