A first driving motor 32 that drives the grabbing mechanism 33 to move is provided at one end of the moving guide beam 31. The grabbing mechanism 33 includes a moving seat 331 that is slidably connected to the moving guide beam 31, a driving cylinder 332 is provided on the moving seat 331, and a vacuum suction cup 333 is provided at the lower end of the piston rod of the driving cylinder 332; a guide assembly 334 is provided on both sides of the driving cylinder on the moving seat 331, and the guide assembly 334 includes a guide sleeve provided on the moving seat 331 and a guide rod slidably connected in the guide sleeve, and the lower end of the guide rod is fixedly connected to the vacuum suction cup 333. The vacuum suction cup 333 includes a suction cup plate body 3331, and the suction cup plate body 3331 has a plurality of positioning guide grooves 3332 distributed in a divergent manner from the center of the plate body to the four corners and the opposite sides of the plate body, and a suction cup assembly 3333 is slidably connected in each positioning guide groove 3332, and the suction cup assembly 3333 can adjust the position along the positioning guide groove 3332 to meet the grasping requirements of workpiece pallets 5 of different sizes. A suction cup cylinder 7 is provided corresponding to the vacuum suction cup 333, and the suction cup cylinder 7 is connected to the suction cup assembly 3333 through a plurality of conveying hoses, and the suction cup cylinder 7 can control the air supply or suction of the vacuum suction cup 333 to facilitate the grasping or putting down of the workpiece pallet.

[0039] The working principle or working method of the utility model:

[0040] The material receiving device 100 of the present application is used in conjunction with an injection molding machine. When working, multiple empty workpiece pallets 5 are placed on the conveying mechanism 9 corresponding to the material receiving chamber 13. In the initial state, the stacked multiple empty workpiece pallets 5 are located outside the conveying mechanism 9, that is, the empty workpiece pallets 5 are located outside the material receiving chamber 13. After the injection molding machine completes the thermoplastic molding of a batch of plastic workpieces, the plastic workpieces are manually cut and the empty workpiece pallets 5 are placed one by one. After a tray is filled, the through-hole conveying mechanism 9 delivers the stacked workpiece pallets as a whole into the material receiving chamber 13, and then the workpiece pallets 5 filled with workpieces are transferred to the output chamber 11 through the transfer and grasping mechanism 3. At this time, the lifting bracket 42 located in the output chamber 11 is controlled to rise to a high position along the lifting guide beam 41 to facilitate the placement of the workpiece pallet 5 filled with workpieces. The above process is repeated, and the multiple empty workpiece pallets 5 on the conveying mechanism 9 of the receiving chamber 13 are transferred to the output chamber 11 one by one by the transfer grasping mechanism 3 along with the workpieces contained therein. The lifting bracket 42 in the receiving chamber 13 needs to be gradually lifted upwards to allow the top workpiece pallet of the stacked workpiece pallets 5 to be grasped, while the lifting bracket 42 in the output chamber 11 needs to be gradually lowered to allow multiple full workpiece pallets 5 to be stacked one by one. When the number of workpiece pallets full of workpieces stacked in the output chamber 11 reaches a preset number, the lifting bracket 42 is controlled to descend to the lowest point and disengage from the stacked workpiece pallets, and the stacked workpiece pallets are seated on the corresponding conveying mechanism 9. The conveying mechanism 9 is controlled to send the workpiece pallets full of workpieces out of the output chamber 11, and workers can use tools such as forklifts to transfer the workpiece pallets full of workpieces at one time. This type of receiving device has a high degree of automation and can automatically, continuously and efficiently realize the automatic loading of plastic workpieces.

[0041] Reduce the occupancy of staff and reduce the workload of staff.

[0042] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
