[0028] The following will describe in detail the preferred embodiments of the present utility model in conjunction with the accompanying drawings.

[0029] Refer to Figures 1 to 6 , the present utility model provides an automatic feeding machine, including: a frame 1, a conveyor line 2, a lifting mechanism 3 and a handling mechanism 4. The frame 1 is provided with a feeding channel, a lifting station, a picking station, a first discharging station and a second discharging station. The conveyor line 2 and the lifting mechanism 3 are both arranged in the feeding channel. The conveyor line 2 is used to convey a plurality of stacked trays 5 along the feeding channel to the lifting station; the lifting mechanism 3 is used to lift the plurality of stacked trays 5 conveyed to the lifting station step by step upward, so that the topmost tray 5 can be lifted to the picking station. The handling mechanism 4 is installed on the frame 1 and above the feeding channel. The handling mechanism 4 is used to pick up the materials placed in the tray 5 at the picking station and transfer them to the first discharging station. The handling mechanism 4 is also used to pick up the empty tray 5 at the picking station and transfer it to the second discharging station to stack the empty trays 5.

[0030] For the convenience of understanding, in this embodiment, it is defined that the direction of the long side of the frame 1 is the X-axis direction, and the direction of the wide side is the Y-axis direction.

[0031] Among them, the handling mechanism 4 includes an X-axis driving device 41 arranged along the X-axis direction, a Y-axis driving device 42 arranged along the Y-axis direction, a first picking and placing component 43, and a second picking and placing component 44. The first picking and placing component 43 is used to pick up the materials placed in the tray 5 and can be jointly driven by the X-axis driving device 41 and the Y-axis driving device 42 to perform two-dimensional movement to realize automatic feeding of the materials. The second picking and placing component 44 is used to pick up the empty tray 5 and can be driven by the Y-axis driving device 42 to perform linear movement along the Y-axis direction to realize automatic discharging of the tray 5.

[0032] In the utility model, a conveying line 2, a lifting mechanism 3, and a handling mechanism 4 are arranged on the frame 1. Through the conveying line 2, several stacked trays 5 can be conveyed at one time, eliminating the need for manual placement one by one and reducing the labor intensity. After several stacked trays 5 reach the lifting station, they are gradually lifted upward by the lifting mechanism 3 so that the topmost tray 5 can be lifted to the picking station for the handling mechanism 4 to grab and feed. When the handling mechanism 4 has completed feeding all the materials in the topmost tray 5 and the empty tray 5 has also been transferred out by the handling mechanism 4, the lifting mechanism 3 lifts several stacked trays 5 upward so that the current topmost tray 5 is lifted to the picking station for the handling mechanism 4 to continue to grab and feed. This feeding method has good continuity, low cost, and can realize efficient, accurate, and stable automatic feeding of materials.

[0033] It is worth mentioning that the frame 1 is also provided with a discharging channel arranged side by side with the feeding channel. The discharging channel is also provided with a conveying line 2 and a lifting mechanism 3. The lifting mechanism 3 in the discharging channel is used to receive the empty tray 5 transferred to the second discharging station by the handling mechanism 4 and can drive the tray 5 to gradually descend, thereby cooperating with the handling mechanism 4 to realize automatic stacking of the empty trays 5 and reducing the labor intensity. The conveying direction of the conveying line 2 in the discharging channel is opposite to that of the conveying line 2 in the feeding channel. When the stacked empty trays 5 on the lifting mechanism 3 in the discharging channel reach a certain number, the lifting mechanism 3 in the discharging channel will drive several stacked empty trays 5 to descend until several stacked empty trays 5 land on the conveying line 2 in the discharging channel, and the conveying line 2 conveys the stacked empty trays 5 out, thereby realizing automatic recycling of the empty trays 5.

[0034] In this embodiment, the conveying line 2 and the lifting mechanism 3 in the feeding channel and the discharging channel have the same structure. The following mainly takes the conveying line 2 and the lifting mechanism 3 in the feeding channel as examples for elaboration.

[0035] Refer to Figure 2, the conveyor line 2 includes two synchronous belt mechanisms 21 arranged side by side at intervals, and a first drive motor 22 drivingly connected to the two synchronous belt mechanisms 21. The first drive motor 22 is used to drive the two synchronous belt mechanisms 21 to rotate synchronously, so as to carry a plurality of stacked trays 5 and convey them towards the lifting station.

[0036] In order to be applicable to trays 5 of different shapes and sizes, the distance between the two synchronous belt mechanisms 21 in the present utility model is adjustable.

[0037] Specifically, the automatic loading machine of the present utility model further includes an adjusting mechanism 6 and two support plates 7 mounted on the frame 1. The two synchronous belt mechanisms 21 are respectively mounted on the inner sides of the two support plates 7 facing each other. The adjusting mechanism is used to drive one of the support plates 7 to move, so as to approach or move away from the other support plate 7, thereby changing the distance between the two synchronous belt mechanisms 21. Of course, the adjusting mechanism can also drive the two support plates 7 to move simultaneously, so that the two support plates 7 approach or move away from each other, and the distance between the two synchronous belt mechanisms 21 can also be changed.

[0038] In this embodiment, the adjusting mechanism is specifically adopted to drive the two support plates 7 to move simultaneously.

[0039] As Figure 2 shown, a plurality of second slide rails 9 are fixed on the frame 1 along the Y-axis direction. The two support plates 7 are respectively slidably fitted on the corresponding second slide rails 9 through sliders. The adjusting mechanism 6 includes a second lead screw 61. The second lead screw 61 is a bidirectional lead screw, and its two ends are rotatably mounted on the frame 1 through two brackets 62; second lead screw nuts 63 are fixed on both support plates 7, and both second lead screw nuts 63 are sleeved on the second lead screw 61. A handwheel is fixed at one end of the second lead screw 61. When the handwheel is rotated to drive the second lead screw 61 to rotate, under the action of the two second lead screw nuts 63, the support plates 7 are driven to approach or move away from each other, thereby reducing or increasing the distance between the two synchronous belt mechanisms 21, so as to be applicable to trays 5 of different shapes and sizes. For different types of materials, there is no need to replace the equipment, and the use is more flexible.

[0040] Of course, the handwheel can also be replaced with a motor to achieve automatic adjustment.

[0041] Among them, baffles 8 are fixed on the tops of the two support plates 7. The loading channel is located between the two baffles 8. The baffles 8 are used to prevent the plurality of stacked trays 5 conveyed by the conveyor line 2 from tipping over.

[0042] Similarly, the conveyor line 2 in the unloading channel is also adjustable.

[0043] Exemplarily, both the X-axis driving device 41 and the Y-axis driving device 42 can adopt a linear motor module, a ball screw type linear module, a synchronous belt type linear module, etc. In this embodiment, a ball screw type linear module is preferably used.

[0044] Refer to Figure 3 Figure 3 , the handling mechanism 4 further includes a first slide rail 45 and a bottom plate 46 arranged in parallel with the Y-axis driving device 42. The first slide rail 45 is fixed on the frame 1. One end of the bottom plate 46 is fixedly connected to the slide table of the Y-axis driving device 42, and the other end of the bottom plate 46 is slidably fitted on the first slide rail 45 through a slider. The X-axis driving device 41 is installed on the top of the bottom plate 46.

[0045] Refer to Figure 3 and Figure 4 Figure 4 , the first picking and placing component 43 includes a first air cylinder 431, a third driving motor 432 and a plurality of first vacuum suction cups 433. The first air cylinder 431 is installed on the slide table of the X-axis driving device 41 through a first air cylinder fixing plate 435. The third driving motor 432 is connected to the first air cylinder 431 through a motor mounting plate, and a rotating block 434 is fixed on the motor shaft of the third driving motor 432. A plurality of first vacuum suction cups 433 are all installed on the rotating block 434. The third driving motor 432 is used to drive the rotating block 434 to drive the first vacuum suction cups 433 to rotate, so as to facilitate grasping materials of different sizes; the first air cylinder 431 is used to drive the third driving motor 432 to drive a plurality of first vacuum suction cups 433 to move up and down, so as to facilitate picking and placing materials.

[0046] Further, the second picking and placing component 44 includes a second air cylinder 441 and a plurality of second vacuum suction cups 442. A second air cylinder fixing plate 443 is fixed on the bottom plate 46. The second air cylinder 441 is installed on the second air cylinder fixing plate 443 in the vertical direction, and a suction cup fixing plate is installed on the second air cylinder 441. A plurality of second vacuum suction cups 442 are all installed on the suction cup fixing plate. The second air cylinder 441 is used to drive a plurality of second vacuum suction cups 442 to move up and down, so as to facilitate picking and placing the tray 5.

[0047] Exemplarily, the first air cylinder 431 and the second air cylinder 441 can adopt slide table air cylinders.

[0048] It should be noted that since a plurality of materials are placed on each tray 5, the first picking and placing component 43 needs to be jointly driven by the X-axis driving device 41 and the Y-axis driving device 42 to perform two-dimensional movement to realize grasping materials at different positions of the tray; while the blanking of the empty tray 5 only needs to be transported along the Y-axis to the second discharging station, so the second picking and placing component 44 is installed on the bottom plate 46 and is driven by the Y-axis driving device 42 to move along the Y-axis, and no longer needs to be driven by the X-axis driving device 41.

[0049] Refer to Figure 5 and Figure 6, the lifting mechanism 3 includes a lifting fork 31 slidably mounted on the frame 1 and a lifting drive device connected to the lifting fork 31. The lifting fork 31 is horizontally disposed between two synchronous belt mechanisms 21, and the lifting drive device is used to drive the lifting fork 31 to move up and down in the vertical direction.

[0050] Among them, two guide columns 32 are fixedly arranged on the frame 1 in the vertical direction. A lifting block 33 is slidably fitted on the two guide columns 32, and the lifting fork 31 is fixedly connected to the lifting block 33. The lifting drive device includes a first lead screw 34 rotatably mounted on the frame 1 in the vertical direction, a first lead screw nut 35 sleeved on the first lead screw 34 and fixedly connected to the lifting block 33, and a second drive motor 36 drivingly connected to the first lead screw 34. When the second drive motor 36 drives the first lead screw 34 to rotate, under the action of the first lead screw nut 35, the lifting block 33 and the lifting fork 31 are driven to move up and down along the guide columns 32, so as to realize the step-by-step upward lifting of several stacked pallets 5.

[0051] It can be seen that the present utility model sets the conveyor line 2, the lifting mechanism 3 and the handling mechanism 4 on the frame 1. Through the conveyor line 2, several stacked pallets 5 can be conveyed at one time, without manual placement one by one, reducing the labor intensity; after several stacked pallets 5 reach the lifting station, they are step-by-step lifted upward by the lifting mechanism 3, so that the topmost pallet 5 can be lifted to the picking station for the handling mechanism 4 to grab and feed; when the handling mechanism 4 has completely fed all the materials in the topmost pallet 5 and the empty pallet 5 has also been transferred out by the handling mechanism 4, the lifting mechanism 3 lifts several stacked pallets 5 upward, so that the current topmost pallet 5 is lifted to the picking station for the handling mechanism 4 to continue to grab and feed. This feeding method has good continuity, low cost, and can realize efficient, accurate and stable automatic material feeding.

[0052] In the above description, many specific details are elaborated to fully understand the present utility model. However, the above description is only the preferred embodiment of the present utility model, and the present utility model can be implemented in many other ways different from those described herein. Therefore, the present utility model is not limited by the specific implementation disclosed above. At the same time, any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes.
