[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 2 As shown, the automatic feeding device for insert injection molded metal parts proposed in this utility model includes a robotic arm and a base plate 1 mounted on the robotic arm. The robotic arm drives the base plate 1 to move. A mounting plate 2 is slidably mounted on the base plate 1, and multiple sliding rods 201 are fixedly mounted on the mounting plate 2. The sliding rods 201 are slidably connected to the base plate 1, and a drive plate 202 is fixedly mounted at one end of each sliding rod 201. A cylinder 5 is fixedly mounted on the base plate 1, and the output shaft of the cylinder 5 is fixedly connected to the drive plate 202. The mounting plate 2 can be moved on the base plate 1 by the cylinder 5.

[0024] like Figures 1 to 3 As shown, the automatic feeding device in this embodiment also includes multiple connecting holes 3 and suction connectors 4 provided on the mounting plate 2. The suction connectors 4 are fixedly connected to any of the connecting holes 3. Any one or a combination of offset components and extension components are installed on the suction connectors 4. A suction cup 408 is fixedly connected to the offset components and extension components. The extension components control the height of the suction cup 408, and the offset components control the position of the suction cup 408. The suction connectors 4 can be directly connected to the suction cup 408 after either the extension components or the offset components are installed separately. Alternatively, the extension components can be installed first, followed by the offset components, and then the suction cup 408 can be installed on the offset components. The offset components can increase the height of the suction cup 408. The extension components allow multiple suction cups 408 to be on the same plane or multiple planes, thus adapting to different heights of the metal parts within the injection mold.

[0025] Furthermore, the adsorption connector 4 includes a connecting rod 401, on which a limiting plate 402 is fixedly mounted. One end of the connecting rod 401 has a thread 403, and a nut 404 is threaded onto the thread 403. During connection, the connecting rod 401 is inserted into the connecting hole 3, and the nut 404 is installed on the connecting rod 401 and then tightened, thus mounting the connecting rod 401 onto the mounting plate 2. The connecting rod 401 has an air hole 405 penetrating through it. One end of the connecting rod 401 is fixedly mounted with a connector 406 communicating with the air hole 405. Multiple solenoid valves 415 are fixedly mounted on one side of the base plate 1, and the connector 406 and the solenoid valves 415 are connected via an air pipe. The solenoid valves 415 are connected to an air pump device, which can draw air from and release air from the air hole 405, thereby allowing the suction cup 408 to adsorb or release metal parts.

[0026] like Figures 3 to 5As shown, in this embodiment, the extension component includes an extension rod 407 detachably mounted on one end of the connecting rod 401 and communicating with the air hole 405. The suction cup 408 is connected and fixedly connected to the extension rod 407. The extension rod 407 has various specifications, each with a different length. Different lengths of extension rod 407 can be used as needed. The suction cup 408, connected via the extension rod 407, has its axis coaxial with the corresponding connecting hole 3. However, to adapt to different molds, the position of the suction cup 408 may be arbitrary. In this case, the position of the suction cup 408 needs to be offset by an offset component.

[0027] Furthermore, the offset assembly includes an eccentric block 409, which is detachably and rotatably mounted on one end of the extension rod 407 and the connecting rod 401. One end of the eccentric block 409 is threadedly connected to a fastening bolt 410. A guide rod 411 and a lead screw 412 are fixedly installed inside the eccentric block 409. A connecting block 413 is threadedly connected to the lead screw 412. The connecting block 413 is connected to the air hole 405 through a hose 414. The suction cup 408 is connected to and fixedly connected to the connecting block 413. When installing the offset assembly, first install the eccentric block 409 on one end of the extension rod 407 or the connecting rod 401, and rotate the eccentric block 409 to a suitable angle. Then rotate the fastening bolt 410 to apply pressure to the extension rod 407 or the connecting rod 401, which can fix the angle of the eccentric block 409. Then, as needed, the lead screw 412 can be rotated, which can drive the connecting block 413 to move, thereby driving the suction cup 408 to move to a suitable position.

[0028] The working principle of this embodiment is as follows: Based on the position of the metal part in the injection mold, the connecting rod 401 is inserted into the connecting hole 3 near it, and a nut 404 is installed on the connecting rod 401. The nut is then tightened, and the connecting rod 401 is installed on the mounting plate 2. An eccentric block 409 is installed at one end of the extension rod 407 or the connecting rod 401, and the eccentric block 409 is rotated to a suitable angle. Then, the fastening bolt 410 is rotated to apply pressure to the extension rod 407 or the connecting rod 401, thus fixing the angle of the eccentric block 409. Subsequently, the lead screw 412 can be rotated as needed, which moves the connecting block 413, thereby moving the suction cup 408 to a suitable position. Then, the cylinder 5 moves the suction cup 408, and in conjunction with the robotic arm, the metal part can be transported and installed.

[0029] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
