[0027] Referring to Figures 1-7 , the embodiments of the present invention provide a metal part injection molding system, including a loading and unloading robot and an injection molding device;

[0028] The loading and unloading robot includes a robotic arm 1 and a mechanical hand 2. The robotic arm 1 is connected to the mechanical hand 2, and the robotic arm 1 is used to drive the mechanical hand 2. The mechanical hand 2 includes a first adsorption surface 201 and a second adsorption surface 211. The first adsorption surface 201 and the second adsorption surface 211 are arranged oppositely. The first adsorption surface 201 is provided with a plurality of first adsorption stations 202, and the second adsorption surface 211 is provided with a plurality of second adsorption stations 214. The first adsorption stations 202 and the second adsorption stations 214 are arranged oppositely. The first adsorption stations 202 and the second adsorption stations 214 are used for alternately unloading and loading the injection molding device.

[0029] The injection molding device includes a plurality of injection molding mechanisms and an injection molding turntable 8. The injection molding turntable 8 is provided with a first mold 9 and a second mold 12. The first mold 9 and the second mold 12 are used for alternately loading and injection molding. The injection molding mechanism is used for injection molding a metal part so that the first sheet metal and the second sheet metal of the metal part are isolated from each other.

[0030] Specifically, the metal part injection molding system includes a loading and unloading robot and an injection molding device. The loading and unloading robot transfers the metal part 203 to be processed to the injection molding device for injection molding, and first adsorbs and removes the metal part 212 that has been injection molded on the injection molding device through the first adsorption surface 201 or the second adsorption surface 211, and then places the transferred metal part 203 to be processed on the injection molding device for injection molding, so that loading and unloading can be alternated, and the working efficiency is high. The loading and unloading robot consists of a robotic arm 1 and a manipulator 2, and the manipulator 2 is driven to work by the robotic arm 1. The manipulator 2 is provided with a first adsorption surface 201 and a second adsorption surface 211, and the first adsorption surface 201 and the second adsorption surface 211 are arranged oppositely, so that the first adsorption surface 201 and the second adsorption surface 211 can be switched and used with each other. The first adsorption surface 201 and the second adsorption surface 211 are perpendicular to each other. When the first adsorption surface 201 completes suction / release, the second adsorption surface 211 can also complete suction / release. For example, when the first adsorption surface 201 sucks the metal part to be processed to the injection molding device, the robotic arm 1 drives the second adsorption surface 211 of the manipulator 2 to adsorb and remove the metal part 212 that has been injection molded on the injection molding device, and then places the metal part 203 to be processed on the first adsorption surface 201 on the injection molding device for corresponding injection molding, or when the second adsorption surface 211 sucks the metal part to be processed to the injection molding device, the robotic arm 1 drives the first adsorption surface 201 of the manipulator 2 to adsorb and remove the metal part 212 that has been injection molded on the injection molding device, and then places the metal part 203 to be processed on the second adsorption surface 211 on the injection molding device for corresponding injection molding. The first adsorption surface 201 is provided with a plurality of first adsorption stations 202, and the second adsorption surface 211 is provided with a plurality of second adsorption stations 214. The first adsorption stations 202 and the second adsorption stations 214 are arranged oppositely, so as to ensure that the first adsorption surface 201 and the second adsorption surface 211 can complete the same operation of sucking or releasing metal parts. The first adsorption station 202 is configured to suck the metal part 203 to be processed to the processing station of the injection molding device for processing, and the second adsorption station 214 is configured to suck the injection molded metal part 212 that has been processed, or the second adsorption station 214 is configured to suck the metal part 203 to be processed to the processing station of the injection molding device for processing, and the first adsorption station 202 is configured to suck the injection molded metal part 212 that has been processed. The first adsorption stations 202 and the second adsorption stations 214 alternately suck metal parts, that is, after the second adsorption station 214 grabs the injection molded metal part 212 that has been processed, the manipulator 2 is flipped, and the metal part 203 to be processed sucked by the first adsorption station 202 is placed on the processing station of the injection molding device for processing, or after the first adsorption station 202 grabs the injection molded metal part 212 that has been processed, the manipulator 2 is flipped, and the metal part 203 to be processed sucked by the second adsorption station 214 is placed on the processing station of the injection molding device for processing.Thus, feeding and discharging can be successively completed by a manipulator 2, reducing the occupation of robot and manipulator 2 resources and avoiding the potential interference between multiple robots or multiple manipulators 2. The injection molding device includes multiple injection molding mechanisms and an injection molding turntable 8. The injection molding turntable 8 is provided with a first mold 9 and a second mold 12.

Moreover, the first mold 9 has multiple first injection frames 10, and the second mold 12 has multiple second injection frames 11. The first mold 9 and the second mold 12 are oppositely arranged on the injection molding turntable 8. Referring to Fig. 1-2, when the first mold 9 rotates to the feeding port for feeding, the second mold 12 rotates to the injection molding pipeline 6 of the injection molding mechanism for injection molding. After the metal parts in the second injection frame 11 of the second mold 12 are injection molded, the first mold 9 is rotated to the injection molding pipeline 6 for injection molding, and the manipulator 2 sucks out the injection molded metal parts 212 in the second injection frame 11. At the same time, the manipulator 2 places the metal parts 203 to be processed in the second injection frame 11 and transfers the injection molded metal parts 212 to the next process; after completion, it repeats sucking the metal parts 203 to be processed on the feeding platform, so as to perform the next feeding and discharging. The first sheet metal and the second sheet metal of the injection molded metal parts 212 are isolated from each other, and the first sheet metal and the second sheet metal are isolated by injection molding, so as to prevent the first sheet metal and the second sheet metal from affecting each other.

The injection molding platform 5 matches the first adsorption surface 201 and the second adsorption surface 211 respectively, so as to ensure that multiple metal parts 203 to be processed are placed on the injection molding platform 5 at one time, with high working efficiency. The injection molding mechanism includes an injection molding box 7 and an injection molding pipeline 6. The injection molding box 7 stores liquid plastic. The injection molding boxes 7 of multiple injection molding mechanisms can be the same injection molding box 7 or different injection molding boxes 7. Different injection molding boxes 7 store different liquid plastics, so as to injection mold metal parts of different injection molding types. The injection molding pipeline 6 is communicated with the injection molding box 7, and the liquid plastic in the injection molding box 7 is injected into the metal parts on the injection molding platform 5 through the injection molding pipeline 6, so as to obtain the injection molded metal parts 212.

The injection molded metal parts 212 are adsorbed through the second adsorption holes, and the injection molded metal parts 212 are moved to the next process through the metal part injection molding system. Since the mass of the injection molded metal parts 212 after processing is greater than that of the metal parts 203 to be processed, in order to ensure stable adsorption, the number of the second adsorption holes is appropriately increased.
