[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 , the utility model provides a technical solution:

[0028] A full tray unloading mechanism includes an in-and-out component, which includes a silo bottom plate 1 and multiple shaft supports 2. The shaft supports 2 are fixedly installed on the bottom of the silo bottom plate 1. The top surface of the silo bottom plate 1 is fixedly installed with an in-and-out guide rail 9. It also includes a silo assembly. The silo assembly includes a first sliding bottom plate 7 and a second sliding bottom plate 8. The first sliding bottom plate 7 is slidably connected to the silo bottom plate 1 through the in-and-out guide rail 9, and the second sliding bottom plate 8 is slidably connected to the first sliding bottom plate 7 through the auxiliary guide rail 10. The first sliding bottom plate 7 and the second sliding bottom plate 8 are both provided with a through hole 11 through which the jacking component passes. The silo assembly also includes a first silo vertical plate 17 and a second silo vertical plate 18. The first silo vertical plate 17 is fixedly connected to the second sliding bottom plate 8, and the second silo vertical plate 18 is pivotally connected to the second sliding bottom plate 8 through a pivot block 19. The second silo vertical plate 18 is provided with a snap 20, and the pivot block 19 is provided with a boss 21. The snap 20 and the boss 21 are clamped with each other.

[0029] By setting up the in-and-out assembly for use with the hopper assembly, when the full tray unloading mechanism is fully loaded with pallets 28, the worker can pull the hopper assembly out along the secondary guide rail 10, pull the handle downward, the buckle 20 disengages from the boss 21, and the second hopper vertical plate 18 rotates downward around the pivot block 19, thereby quickly taking out the stacked pallets 28. At this time, the pallet 28 on the positioning assembly is still loading products without stopping the machine, which greatly improves work efficiency.

[0030] It also includes a positioning component, which includes two groups of first positioning brackets 3 and two groups of second positioning brackets 4. A first positioning cylinder 5 is arranged between the first positioning brackets 3, and a second positioning cylinder 6 is arranged between the second positioning brackets 4. The first positioning brackets 3 and the second positioning brackets 4 are provided with in-position sensors 15. The first positioning cylinder 5 and the second positioning cylinder 6 are fixedly installed on the mounting frame 16, and the two ends of the mounting frame 16 are fixedly connected to the first positioning bracket 3 or the second positioning bracket 4.

[0031] By setting the first positioning cylinder 5 and the second positioning cylinder 6, the pallet 28 being loaded with products can be clamped and fixed, thereby improving the stability of the pallet 28 and preventing placement errors. At the same time, the pallet 28 being loaded with products can be separated from the pallet 28 full of products. When the fully loaded pallet 28 is taken out, the pallet 28 being loaded will not be affected, thereby improving work efficiency.

[0032] It also includes a jacking assembly, which includes a jacking base plate 12, a load-bearing column 13 and a jacking second plate 14. The load-bearing column 13 is arranged between the jacking base plate 12 and the jacking second plate 14. The jacking assembly also includes a screw rod 22, which is rotatably arranged between the jacking base plate 12 and the jacking second plate 14. The jacking first plate 29 is installed on the screw rod 22 through a threaded seat. The jacking second plate 14 is provided with a jacking cylinder 23. The jacking cylinder 23 drives the screw rod 22 to rotate through a jacking belt 24 and a jacking driven wheel 25. Lifting columns 26 are provided on the four corners of the jacking first plate 29. The jacking columns 26 pass through the jacking base plate 12 and are installed with a jacking third plate 27. The tray 28 is placed on the jacking third plate 27.

[0033] By providing a lifting assembly, the pallet 28 can be driven to move, which makes it easier for the pallet 28 to be fixed and for the fully loaded pallet 28 to be stacked and screwed together, making it easier for the operator to take it out.

[0034] When in use, the device is moved to the designated position. When working, the pallet 28 bin assembly is empty, and the three-lifting plate 27 is raised to a height near the first positioning cylinder 5. When the external grabbing mechanism places the empty pallet 28 on the three-lifting plate 27, the in-place sensor 15 senses the pallet 28, and the lifting cylinder 23 is started, driving the screw rod 22 to reverse, and the threaded seat is threadedly engaged with the screw rod 22 to drive the lifting plate 29 to drive the lifting column 26 to push the three-lifting plate 27 down, thereby causing the empty pallet 28 to move downward. When the in-place sensor 15 does not sense that the pallet 28 is in place, the first positioning cylinder 5 and the second positioning cylinder 6 clamp the control pallet 28, and the lifting cylinder 23 stops moving at the same time. When the pallet 28 is full of injection molded parts, the first positioning cylinder 5 and the second positioning cylinder 6 are controlled to move. Cylinder 6 releases pallet 28, controls the external grabbing mechanism to place another empty pallet 28 on the full pallet 28, starts the lifting cylinder 23, drives the screw rod 22 to reverse, so that the pallet 28 moves downward, and then controls the first positioning cylinder 5 and the second positioning cylinder 6 to clamp the empty pallet 28. When the full pallet unloading mechanism is fully loaded with pallets 28, the operator can pull the pallet 28 hopper assembly along the secondary guide rail 10, pull the handle downward, the buckle 20 disengages from the boss 21, and the second hopper vertical plate 18 rotates downward around the pivot block 19, thereby quickly taking out the stacked pallets 28. At this time, the pallet 28 on the pallet 28 positioning assembly is still loading products, and there is no need to stop the machine, which improves work efficiency. After taking it out, buckle the buckle 20 on the boss 21, push it back to its original position, and continue working.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
