[0039] 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.

[0040] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 6 The utility model provides an embodiment: a robot double-sided working material picking and unloading fixture, including a base 1, a movable mold 4 is slidably connected to the left side of the top of the base 1, a fixed mold 3 is fixedly connected to the right side of the top of the base 1, a mold groove 11 is opened on the left side of the fixed mold 3, and a pressure plate 12 is fixedly connected to the right side of the movable mold 4. A mechanical arm 15 is provided on the front side of the base 1, and a clamping plate 13 is provided on the top of the mechanical arm 15. A first suction working surface 17 is provided on one side of the clamping plate 13, and a first suction working surface 17 is provided on the other side of the clamping plate 13. There is a second suction working surface 18, and a plurality of avoidance holes 20 are opened on the second suction working surface 18 and the side away from the second suction working surface 18. The inner sides of the plurality of avoidance holes 20 are fixedly connected to suction rings 19. A disassembly mechanism 2 is provided between the robot arm 15 and the clamping plate 13; the outer wall of the suction ring 19 is provided with a white injection molded part 16, and the outer wall of the white injection molded part 16 is provided with a black injection molded part 21; the bottom of the robot arm 15 is fixedly connected to the support base 14, and the support base 14 is provided on the rear side of the base 1;

[0041] Specifically, through the rapid movement and flipping of the robotic arm 15, the white injection molded part 16 can be taken out of the first mold and placed on the second mold fixed mold 3 in a short time, and the injection molded product can be taken out from the second mold movable mold 4, which greatly reduces the production cycle and improves the overall production efficiency. The first suction working surface 17 and the second suction working surface 18 on the splint 13 perform suction operations on different injection molded parts respectively, and the precise suction control of the suction ring 19 and the suction cup can ensure the stable grasping and placement of the injection molded parts, reducing product damage and position deviation caused by improper operation. The support base 14 at the bottom of the robotic arm 15 enables the robotic arm 15 to be stably fixed on the rear side of the base 1. At the same time, the robotic arm 15 can move and flip freely within a certain range to adapt to molds of different positions and angles, thereby improving the flexibility of the fixture. The setting of multiple avoidance holes 20 not only ensures the installation and suction transmission of the suction ring 19, but also reduces the overall volume of the fixture, thereby improving the space utilization rate of the production site.

[0042] Refer to the attached Figure 3The disassembly mechanism 2 includes a connecting column 201, the rear side of the connecting column 201 is fixedly connected to the front side of the robot arm 15, the front side of the outer wall of the splint 13 is fixedly connected to a fixing column 203, the front side of the fixing column 203 is provided with a card slot 204, the outer wall of the connecting column 201 is fixedly connected to a buckle 202, and the outer wall of the buckle 202 is slidably connected to the inner side of the card slot 204;

[0043] Specifically, the splint 13 can be quickly installed on the robotic arm 15 by simply aligning the buckle 202 with the slot 204 and pushing the connecting column 201. When disassembly is required, force is applied to disengage the buckle 202 from the slot 204. The operation is convenient and efficient, which greatly saves the time of installation and disassembly. The disassembly mechanism 2 allows different types of splints 13 to be replaced according to different production needs. When the buckle 202 slides into the slot 204, the two cooperate with each other to firmly connect the splint 13 to the robotic arm 15. During the working process of the clamp, the stability of the splint 13 is guaranteed, and failure of material removal or safety accidents caused by loose connection is prevented, thereby improving the reliability of production.

[0044] Refer to the attached Figure 4 and attached Figure 5 , the top of the base 1 is fixedly connected to a support frame 7, the top of the support frame 7 is fixedly connected to a cylinder 5, one end of the cylinder 5 is fixedly connected to a push plate 6, the outer wall of the push plate 6 is fixedly connected to the outer wall of the movable mold 4; the front and rear sides of the outer wall of the fixed mold 3 are fixedly connected to a slide bar 8, the inner side of the movable mold 4 is slidably connected to the outer wall of the two slide bars 8; the left and right sides of the two slide bars 8 are fixedly connected to baffles 9, and the bottoms of multiple baffles 9 are fixedly connected to the top of the base 1; the outer wall of the movable mold 4 is slidably connected to a slide bar 2 10, and one end of the slide bar 2 10 is fixedly connected to the outer wall of the fixed mold 3;

[0045] Specifically, the support frame 7 on the top of the base 1 provides stable support for the cylinder 5. The cylinder 5 can accurately control the movement of the push plate 6, thereby pushing the movable mold 4 to move smoothly on the slide bar 1 8 and the slide bar 2 10. This stable driving method ensures the position accuracy of the movable mold 4 during the working process and improves the molding quality of the injection molded parts. The inner side of the movable mold 4 is slidably connected to the outer wall of the two slide bars 1 8, and the outer wall of the movable mold 4 is slidably connected to the slide bar 2 10. These slide bars provide precise guidance for the movement of the movable mold 4, so that the movable mold 4 can move along a predetermined straight line trajectory during the opening and closing process, avoiding dimensional deviation of the injection molded parts or damage to the mold due to offset, and ensuring the stability and reliability of production. The left and right sides of the two slide bars 1 8 are fixedly connected with baffles 9. On the one hand, these baffles 9 can prevent the movable mold 4 from detaching from the slide bars during movement.

[0046] Working principle: The robot arm 15 is fixed to the back side of the base 1 through the support base 14 and is ready to work. When the white injection molding of the injection molded part on the first mold is completed, the robot arm 15 drives the clamping plate 13 to move to the first mold. The suction ring 19 on the first suction working surface 17 on one side of the clamping plate 13 generates suction through the suction cup to suck the white injection molded part 16 from the first mold. Then the robot arm 15 flips over and moves the clamping plate 13 sucking the white injection molded part 16 to the top of the fixed mold 3 of the second injection mold, and places the white injection molded part 16 into the mold slot 1 on the left side of the fixed mold 3. 1, at the same time, the second suction working surface 18 on the other side of the clamping plate 13 is close to the black + white injection molded parts that have been formed on the second mold movable mold 4, and the suction ring 19 on the second suction working surface 18 generates suction through the suction cup to suck the black + white injection molded parts off the second mold movable mold 4. After completing the material picking and placing operation, the robot arm 15 can proceed to the next step as needed, or repeat the above process, and when it is necessary to install the clamping plate 13 on the robot arm 15, align the buckle 202 on the connecting column 201 with the slot 204 on the front side of the fixing column 203. Then push the connecting column 201 closer to the fixed column 203, so that the buckle 202 slides into the inner side of the slot 204. At this time, the buckle 202 and the slot 204 cooperate with each other to firmly connect the splint 13 to the robotic arm 15. When the splint 13 needs to be removed, force is applied to make the buckle 202 slide in the slot 204 and disengage from the slot 204, so that the splint 13 can be removed from the robotic arm 15.
