The movable end of the third cylinder 681 is located in the nut sleeve 684. The nut sleeve 684 is used to temporarily store the H23 nuts pre-embedded in the extension stroke of the movable end of the first cylinder 591. When the feeding fixture 600 picks up the material, the feeding fixture 600 is positioned by the positioning hole and the positioning pin 58. The movable end of the first cylinder 591 pushes the pre-embedded H23 nuts into the nut sleeve 684. When the feeding fixture 600 picks up the material, the movable end of the second cylinder 681 extends and pushes the H23 nuts in the nut sleeve 684 into the mold 700.

[0046] In a further embodiment, the upper part of the second side plate 61 is also provided with a fourth mounting plate 67, and the fourth mounting plate 67 is provided with a plurality of suction cups 69 along the second direction Y. The suction cups 69 are used to pick up the control box 300 produced on the mold 700; wherein, the second side plate 61 is also provided with a mold positioning pin 66 in the second direction for positioning with the mold 700.

[0047] like Figures 9-11As shown, this utility model also provides a control box nut mounting device, including the aforementioned control box mounting fixture, as well as a mold 700 for producing the control box 300, a frame 100 for placing the material preparation fixture 500 and the control box 300, and a robotic arm 200 for controlling the loading fixture 600. The end of the robotic arm 200 can move along the first direction X, the second direction Y, and the third direction Z and is rotatably connected to the loading fixture 600 around the first direction. In this embodiment, a worktable is provided inside the frame 100, and three side walls of the frame 100 are provided with plexiglass or PC board, with one side being open. The placement is designed to facilitate operation by relevant personnel. Since the robotic arm 200 is located on one side of the preparation fixture 500, a rotary cylinder 400 is provided at the bottom of the preparation fixture 500. When the nut is manually installed onto the preparation fixture 500, the rotary cylinder 400 drives the preparation fixture 500 to rotate 90° to facilitate the loading fixture 600 to grasp it. The robotic arm 200 and the control system of the entire equipment are existing technologies, so they will not be described in detail here. The frame 100 is also equipped with a heat dissipation platform 11, control buttons 12 and light grid 13. The heat dissipation platform 11 is equipped with a fan for rapid heat dissipation of the mold 300.

[0048] Workflow: At least one set of H23 nuts, four sets of H15 nuts, and four sets of H18 nuts are manually placed onto the first cylinder 591, the second cylinder 592, and the positioning pin 510, respectively. At this time, the movable end is in the retracted state. After manual loading, the rotary cylinder 400 rotates the preparation fixture 500 90°. Control button 12 controls the robotic arm 200 to drive the preparation fixture 600 to align with the positioning pin 58 through its positioning hole. After alignment, the movable ends of the first cylinder 591 and the second cylinder 592 push the corresponding nuts into the nut sleeve 684. The pneumatic finger cylinder 65 clamps the nut on the positioning post 510. After the feeding mold 600 finishes gripping, the robotic arm 200 reaches the mold 700 and uses the suction cup 69 to pick up the control box 300. The robotic arm 200 moves up to the nut placement position on the mold 700 and starts the cylinder to push the nut into the mold 700. After the robotic arm 200 completes the nut placement operation, the feeding fixture 600 at the end of the robotic arm 200 rotates 90° and uses the feeding fixture 600 to place the control box 300 on the designated heat dissipation platform 11 for heat dissipation. Then the robotic arm 200 returns to its original position and repeats the above process.

[0049] In this invention, different quantities and types of nuts are manually placed at a set position using a preparation fixture 500. A robotic arm 200 controls a loading fixture 600 to pick up the placed nuts from the preparation fixture 500. The loading fixture 600 then uses a cylinder to install the nuts onto a designated position on a mold 700. Simultaneously, the loading fixture 600 uses a suction cup 69 to pick up the completed control box 300 from the mold 700. This invention not only improves the production efficiency of the control box 300 but also enhances safety during production.

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
