The conveying mechanism includes a first conveying structure 21 and a second conveying structure. The first conveying structure 21 is used to convey the molds before palletizing, and the second conveying structure is used to convey the molds after palletizing. The palletizing mechanism is used to transfer the molds on the first conveying structure 21 to the second conveying structure. The palletizing mechanism includes a mounting base 31, a lifting assembly, a rotating assembly and an adsorption assembly. The mounting base 31 is connected to the lifting assembly through a rotating structure. The lifting assembly is connected to the rotating assembly, and the rotating assembly is connected to the adsorption assembly. The adsorption assembly is used to adsorb the molds. The adsorption assembly includes a detachable adsorption disk 351 group, a receiving block 352 and a sealing sleeve 354. The receiving block 352 is connected to the rotating assembly. An installation groove 352a is opened on the receiving block 352. The sealing sleeve 354 is located in the installation groove 352a. The sealing sleeve 354 is installed in the installation groove 352a through an installation plate 353. Specifically, a clamping groove is opened in the installation groove 352a, and the end of the installation plate 353 is clamped in the clamping groove. The sealing sleeve 354 is connected to the installation plate 353.

[0030] In this embodiment, a plurality of pipe sleeves 355 are provided on the sealing sleeve 354. The detachable suction disc group 351 includes a plurality of suction discs 351. Different suction discs 351 are applicable to different molds. Each suction nozzle 351a on the suction disc 351 is matched with a pipe sleeve 355 and is in interference fit with the corresponding pipe sleeve 355. Specifically, a plurality of inner pipes are connected to the suction disc 351, and each inner pipe is inserted into the corresponding pipe sleeve 355. The inner pipe is in interference fit with the corresponding pipe sleeve 355 to ensure strong sealing between the inner pipe and the pipe sleeve 355. An air vent passage is provided on the suction disc 351, and each inner pipe is communicated with the corresponding suction nozzle 351a through the air vent passage. It should be noted that the suction assembly further includes a vacuum pump. The vacuum pump is communicated with the sealing sleeve 354 through a vacuum pipe 356. The vacuum pump performs vacuum pumping treatment. A vacuum valve is provided on the vacuum pipe 356, and the vacuum valve is used to control the connection between the vacuum pipe 356 and the vacuum pump or the outside.

[0031] In this embodiment, the suction disc 351 is connected to the receiving block 352 through a disassembly structure. The disassembly structure includes a receiving plate 51, a connecting spring 52, and a bolt member 53. The receiving plate 51 is connected to the receiving block 352 through the bolt member 53, and the receiving plate 51 is connected to the suction disc 351 through the connecting spring 52. Specifically, the receiving plate 51 is parallel to the suction disc 351. The connecting spring 52 is located between the receiving plate 51 and the suction disc 351. One end of the connecting spring 52 is connected to the receiving plate 51, and the other end of the connecting spring 52 is connected to the suction disc 351. The connecting spring 52 is used to pull the inner pipe to move towards the direction of the pipe sleeve 355. A through slot for the pipe sleeve 355 to pass through is provided on the receiving plate 51. A through hole is provided on the receiving plate 51, and a threaded hole is provided on the receiving block 352. The threaded hole is threadedly connected to the bolt member 53. It should be noted that during the process of connecting the suction disc 351 and the receiving block 352 through the disassembly structure member, each pipe sleeve 355 passes through the corresponding through slot, and then the inner pipe is inserted into the pipe sleeve 355. The receiving plate 51 is pulled towards the receiving block 352 to make the through hole on the receiving plate 51 correspond to the threaded hole on the receiving block 352. Then the bolt member 53 is passed through the through hole and connected to the threaded hole to fix the receiving plate 51. At this time, the connecting spring 52 is in a stretched state, and the connecting spring 52 drives the inner pipe to move towards the direction of the pipe sleeve 355, so that the inner pipe is in interference fit with the pipe sleeve 355, thereby realizing the connection between the suction disc 351 and the receiving block 352.

[0032] It can be understood that in order to improve the sealed connection relationship between the inner pipe and the pipe sleeve 355, a sealing sleeve 354 is sleeved on the inner pipe.

[0033] In this embodiment, the rotating structure includes a first servo motor and a rotating carrier 32. The first servo motor is connected to the center of the rotating carrier 32 through a planetary reducer. The rotating carrier 32 is rotatably connected to the mounting base 31. The lifting assembly is arranged on the rotating carrier 32. The first servo motor is used to drive the rotating carrier 32 to rotate through a full angle, and the planetary reducer is used to improve the smoothness of the rotation of the rotating carrier 32.

[0034] In this embodiment, the lifting assembly includes a pneumatic structure 331, a piston rod, and a receiving frame 333. The receiving frame 333 is sleeved on the piston rod. The piston rod is connected to the pneumatic structure 331. The receiving frame 333 is connected to the rotating assembly. The pneumatic structure 331 is arranged on the rotating carrier 32. The pneumatic structure 331 is used to provide a force to drive the piston rod and the receiving frame 333 to perform a lifting motion. It should be noted that the pneumatic structure 331 is a cylinder structure, and this cylinder structure is a prior art, so it will not be described in detail here.

[0035] In this embodiment, the receiving frame 333 includes a first receiving portion and a second receiving portion that are perpendicular to each other. The first receiving portion is connected to the piston rod. The other end of the first receiving portion is connected to one end of the second receiving portion. Both the first receiving portion and the second receiving portion are located above the rotating carrier 32. The second receiving portion is connected to the rotating assembly.

[0036] In this embodiment, the rotating assembly includes a second servo motor 342 and a rotating connecting plate 341. The rotating connecting plate 341 is rotatably connected to the other end of the second receiving portion. The second servo motor 342 is installed on the second receiving portion of the receiving frame 333. The output shaft of the second servo motor 342 is connected to the center of the rotating connecting plate 341. The rotating connecting plate 341 is located below the second receiving portion. The rotating connecting plate 341 is connected to the receiving block 352 of the adsorption assembly. The second servo motor 342 is used to drive the rotating connecting plate 341 to rotate through a full angle.

[0037] In this embodiment, the first conveying structure 21 is a roller conveyor line structure, and this roller conveyor line structure is a prior art, so it will not be described in detail here.

[0038] In this embodiment, the second conveying structure includes a tray, a roller conveyor line 221, and a lifting table 222. The roller conveyor line 221 and the lifting table 222 are both arranged on the workbench. The lifting table 222 is located on one side of the roller conveyor line 221. The tray is conveyed to the lifting table 222 through the roller conveyor line 221. The lifting table 222 performs a lifting motion through a lifting structure. It should be noted that the lifting structure is a cylinder structure, and the cylinder structure is a prior art, so it will not be described in detail here.

[0039] In this embodiment, an induction component is provided on the workbench 10. The induction component is arranged on the side of the lifting table 222 and is used to detect the size of the tray on the lifting table 222. Specifically, the induction component includes an infrared emitter 11 and an infrared receiver 12. A bidirectional screw 13 and a third servo motor 14 are provided on the workbench 10. The bidirectional screw 13 is connected to the output shaft of the third servo motor 14. The bidirectional screw 13 is connected to the workbench 10 through a fixing block 17. The third servo motor 14 is installed on the fixing block 17. Displacement blocks are respectively threadedly connected to both ends of the bidirectional screw 13. The infrared emitter 11 and the infrared receiver 12 are respectively connected to the displacement blocks at both ends of the bidirectional screw 13 through corresponding moving brackets 16. The infrared emitter 11 and the infrared receiver 12 are opposite in position. It can be understood that corresponding threads are provided at both ends of the bidirectional screw 13, and the thread directions at both ends of the bidirectional screw 13 are opposite. When the third servo motor 14 drives the bidirectional screw 13 to rotate, the infrared receiver 12 and the infrared emitter 11 move relatively or in opposite directions.

[0040] It should be noted that in order to prevent the displacement block from rotating along with the rotation of the bidirectional screw 13, a limiting rod is connected to the fixing block 17. The limiting rod contacts the displacement block and is parallel to the bidirectional screw 13.

[0041] In specific implementation, the mold before palletizing is conveyed to the vicinity of the palletizing mechanism through the first conveying structure 21, and then the mold on the first conveying structure 21 is transferred to the second conveying structure by the palletizing mechanism, so that the palletized mold can be conveyed to the storage room by the second conveying structure. During the palletizing process, different adsorption discs 351 are replaced to adapt to the adsorption operations of different molds, realizing the palletizing operation of multiple molds at one working position, so as to reduce the working area required for the palletizing steps, which is beneficial to reducing the purchase quantity of the same equipment and reducing the production cost.

[0042] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the mold palletizing system of the present application has only the above-mentioned unique implementation process. On the contrary, as long as the mold palletizing system of the present application can be implemented, it can be included in the feasible implementation schemes of the present application.
