[0071] When the equipment is running, the third conveyor 43 is connected to the output end of the input conveyor 2, and the input conveyor 2 conveys several material boxes 8 containing the materials to be processed toward the output end of the output conveyor 3 in sequence, until the material box 8 in the first position is conveyed to the third conveyor 43, and then, the first cylinder 51 drives the first baffle 52 to extend to stop the remaining material boxes 8 on the input conveyor 2, and then, the first linear module 42 drives the conveying bracket to rise, and the conveying bracket lifts the third conveyor 43 and the material box 8 containing the materials to be processed on the third conveyor 43 to the picking station of the manipulator, in this state, the third conveyor 43 is connected to the output conveyor 3, and after the manipulator takes out all the materials to be processed stored in the material box 8 on the third conveyor 43 one by one, the third conveyor 43 conveys the material box 8 it carries to the output conveyor 3, and the output conveyor 3 conveys it toward the output end of the output conveyor 3, and the material box 8 is conveyed to the output conveyor After the output end of the device 3, the material box 8 abuts against the limit plate 77. When the output conveyor device 3 is in operation, the limit plate 77 blocks the material box 8 at the output end of the output conveyor device 3 from continuing to move. When the output conveyor device 3 carries multiple material boxes 8, the handling module 7 lifts the material box 8 at the output end of the output conveyor device 3. In this state, the second cylinder 61 drives the second baffle 62 to extend to stop the remaining material boxes 8 conveyed by the output conveyor device 3. After the handling device lifts the material box 8 to a lifting height greater than the height of one material box 8, the second cylinder 61 drives the second baffle 62 to retract. When the output conveyor device 3 is running, the output conveyor device 3 transfers the material box 8 located at the second to last position to the output end of the output conveyor device 3 and makes it abut against the limit plate 77. After that, the handling module 7 puts down the lifted material box 8 so that the two material boxes 8 are stacked together. According to this step, after the handling module 7 stacks multiple material boxes 8 to a certain height, the handling module 7 moves the stacked multiple material boxes 8 to the ground.

[0072] The working principle of the handling module 7 is as follows:

[0073] When the transport module 7 lifts the material box 8, the second linear module 73 drives the transport bracket 76 to rise, so that the side wall surface of the carrying portion 761 of the transport bracket 76 facing away from the limiting portion 762 abuts against the bottom surface of the transport protrusion 83 of the material box 8. In this state, the limiting portion 762 of the transport bracket 76 abuts against the hinged bracket 75, thereby lifting the material box 8; after the output conveyor device 3 conveys another material box 8 to the lower side of the material box 8 lifted by the transport module 7, the second linear module 73 drives the transport bracket 76 to descend, so that the two material boxes 8 are stacked together; During the process of descending and resetting 76, when the transport bracket 76 interferes with the partial structure of the material box 8 located at the bottom layer, the side wall of the load-bearing portion 761 of the transport bracket 76 facing the limiting portion 762 contacts with the material box 8 located at the bottom layer, causing the transport bracket 76 to flip over a certain angle, thereby avoiding the partial structure of the material box 8 located at the bottom layer. After the transport bracket 76 is reset, the torsion spring drives the transport bracket 76 to flip and reset, causing the limiting portion 762 to abut against the articulated bracket 75 again, so that the output conveying device 3 of the present device can carry more material boxes 8 at the same time, thereby enhancing the practicability of the present device.

[0074] When the transport module 7 moves multiple fallen material boxes 8 to the ground, first, the second linear module 73 drives the transport bracket 76 to rise, so that the side wall surface of the load-bearing portion 761 of the transport bracket 76 facing away from the limiting portion 762 is in contact with the bottom surface of the transport protrusion 83 of the material box 8 located at the bottom layer, thereby lifting the multiple stacked material boxes 8 to a certain height, and then, the first motor 72 drives the connecting rod 71 to swing to a certain angle, and at the same time, the second motor 74 drives the second linear module 73 to rotate synchronously, so that the second linear module 73 maintains a vertical state, and after the multiple stacked material boxes 8 are moved a certain distance away from the output conveying device 3, the first motor 72 and the second motor 74 stop rotating synchronously, and the second linear module 73 drives the transport bracket 76 to descend, thereby placing the multiple stacked material boxes 8 on the ground, further enhancing the degree of automation of the device.

[0075] Above, refer to Figures 1 to 7 An automatic loading device according to an embodiment of the utility model is described, which has the following beneficial effects: the device is provided with a lifting module and an output conveying device to achieve the purpose of conveying the empty material box out of the picking station of the robot after the robot picks up all the materials to be processed in the current material box, thereby enhancing the automation level of the device and solving the defect of low automation level in the prior art.
