Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] See also Figures 1 to 5 The utility model provides a technical solution: an automatic loading device, including a tray rising bin 1, an upper bin 2 and a tray descending bin 3; the tray rising bin 1, the upper bin 2 and the tray descending bin 3 are separated by a frame 11, and the frame 11 also plays a supporting and stabilizing role; the tray rising bin 1 includes a tray rising component 4, and the tray rising component 4 is used to move the full tray to the upper bin 2 after the full tray is raised; the upper bin 2 includes a tray loading component 5, and the tray loading component 5 is used to load the raw materials in the full tray to the next process; the tray descending bin 3 includes a tray descending component 6, and the tray descending component 6 is used to move the empty tray from the upper bin 2 to the tray descending bin 3 and then drive the empty tray to descend.

[0033] In this embodiment, the lifting mechanism 41 in the tray lifting assembly 4 is started, that is, the lifting motor 412 is started to reverse, and the lifting motor 412 reverses to drive the threaded rod 413 to reverse, thereby driving the first tray support 414 to descend. When the first tray support 414 descends to the bottom of the equipment, the lifting motor 412 stops, and then multiple full trays are stacked on the first tray support 414, among which the full tray on the top layer is always located at a position convenient for transplanting by the first moving mechanism 42. A sensor is provided at this position, and the sensor controls the lifting motor 412 to stop when the full tray on the top layer rises to this position. When the tray on the top layer is full, the sensor stops. After the full tray of the layer is transferred to the upper bin 2 by the first moving mechanism 42, the lifting motor 412 rotates forward to drive the first tray support 414 to rise. After the full tray located on the upper layer reaches the designated transfer position under the control of the sensor, the lifting motor 412 stops; the working process of the first moving mechanism 42 is as follows: when the full tray located on the upper layer reaches the transfer position, the four pneumatic clamps 426 are started to contract and clamp the tray. After clamping the tray, the moving motor 422 starts to rotate forward, driving the gear 423 to rotate forward. At this time, the rack 425 is affected by the positive rotation of the gear 423 to move toward the upper bin 2, driving the moving plate 424 to move toward the upper bin 2 The pneumatic grippers 426 and the tray are moved in the same direction, thereby driving the pneumatic grippers 426 and the tray to move to the upper hopper 2. When the full tray reaches the loading position of the upper hopper 2, the four pneumatic grippers 426 are started to extend and the tray is unlocked and placed in the loading position. Then the moving motor 422 is started to reverse and drive the four pneumatic grippers 426 to reset. The working process of the tray loading assembly 5 is as follows: when the full tray reaches the loading position of the upper hopper 2, the first loading slide 51 and the second loading slide 52 are started to cooperate with each other, so that the loading robot 53 can grab the raw materials at any position of the tray and transport them to the next process. When the full tray is empty, it waits to move to the tray lower hopper 3. ; When the trays in the upper hopper 2 are empty, the second moving mechanism 62 in the tray lowering bin 3 is started, wherein the working mode of the second moving mechanism 62 is the same as that of the first moving mechanism 42. When the second moving mechanism 62 is started, the descending mechanism 61 is started to drive the empty trays to descend one tray position, so that the second moving mechanism 62 can transfer the empty trays in the upper hopper 2 to the tray lowering bin 3; wherein when the empty trays stacked in the tray lowering bin 3 are full, the staff will take the empty trays out of the tray lowering bin 3, and when the full trays stacked in the tray ascending bin 1 are emptied, the staff will add new full trays to the tray ascending bin 1.

[0034] For further information, see Figure 2The tray lifting assembly 4 includes a lifting mechanism 41 and a first moving mechanism 42. The lifting mechanism 41 includes a first crossbeam 411.

The output end of the lifting motor 412 is fixedly connected to a threaded rod 413. The outer wall of the threaded rod 413 is screwed with a first tray support 414. The first tray support 414 is used to stack trays full of materials.

[0035] After the full tray on the top layer is transferred to the upper bin 2 by the first moving mechanism 42, the lifting motor 412 rotates forward to drive the first tray support 414 to rise, and the lifting motor 412 stops after the full tray on the top layer reaches the designated transfer position under the control of the sensor; wherein the first tray support 414 is guided in the direction and kept balanced by the guide column during the rising and falling process.

[0036] For further information, see Figure 3 and Figure 4 The tray lifting assembly 4 also includes a first moving mechanism 42, which includes a fixed plate 421. The fixed plate 421 is fixed to the bottom surface of the first beam 411. A moving motor 422 is provided on the top surface of the fixed plate 421. The output end of the moving motor 422 is fixedly connected to a gear 423. A moving plate 424 is provided under the fixed plate 421. The moving plate 424 is slidably connected to the fixed plate 421. A rack 425 is provided on the top surface of the moving plate 424, and the rack 425 matches and meshes with the gear 423.

[0037] For further information, see Figure 3 and Figure 4 The bottom surface of the movable plate 424 is provided with four pneumatic clamps 426 distributed in a matrix. The pneumatic clamps 426 are driven by a cylinder and are used to clamp the material tray.

[0038] In this embodiment, the working process of the first moving mechanism 42 is as follows: when the full material tray located on the top layer reaches the transplanting position, the four pneumatic clamps 426 are started to contract and clamp the material tray. After clamping the material tray, the moving motor 422 starts to rotate forward, driving the gear 423 to rotate forward. At this time, the rack 425 is affected by the forward rotation of the gear 423 and moves toward the upper material bin 2, driving the moving plate 424 to move toward the upper material bin 2, thereby driving the pneumatic clamps 426 and the material tray to move to the upper material bin 2. When the full material tray reaches the loading position of the upper material bin 2, the four pneumatic clamps 426 are started to extend and the material tray is unlocked and placed in the loading position. Then the moving motor 422 starts to reverse and drives the four pneumatic clamps 426 to reset.

[0039] For further information, see Figure 5 The material tray loading assembly 5 includes a first loading slide rail 51, and there are two first loading slide rails 51.

The second loading slide rail 52 is provided with a loading robot 53, and the loading robot 53 can slide along the extension direction of the second loading slide rail 52.

[0040] In this embodiment, the working process of the tray loading assembly 5 is as follows: when the full tray reaches the loading position of the loading bin 2, the first loading slide 51 and the second loading slide 52 are started to cooperate with each other, so that the loading robot 53 can grab the raw materials at any position of the tray and transport them to the next process. When the full tray is empty, it waits to move to the tray lowering bin 3.

The lowering mechanism 61 is used to collect and stack empty trays, and the second moving mechanism 62 is used to transfer empty trays from the upper silo 2 to the tray lowering silo 3.

[0042] In this embodiment, when the tray in the upper bin 2 is empty, the second moving mechanism 62 in the tray lowering bin 3 is started, wherein the working mode of the second moving mechanism 62 is the same as that of the first moving mechanism 42. After the second moving mechanism 62 is started, the descending mechanism 61 is started to drive the empty tray to descend one tray position, so that the second moving mechanism 62 transfers the empty tray in the upper bin 2 to the tray lowering bin 3, wherein the descending mechanism 61 has the same working principle as the ascending mechanism 41.

[0043] The working principle and usage process of the present invention are as follows: start the lifting motor 412 in the tray lifting bin 1 to lower the first tray support 414 to the bottom end, and then the staff stacks multiple full trays on the first tray support 414, and then start the first moving mechanism 42 to move the full tray at the top to the loading position in the upper bin 2, and then the lifting motor 412 lifts the first tray support 414 by one tray height, and then the tray loading assembly 5 transports the raw materials in the tray at the loading position to the next workstation through the loading robot 53. After the tray in the upper bin 2 is emptied, the second moving mechanism 62 is started to transfer the empty tray in the upper bin 2 to the tray support in the tray lowering bin 3, and then the lowering mechanism 61 is lowered by one tray height, and then the above actions are repeated to complete a set of loading processes.
