[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 6 As shown, an automatic hook feeding device includes a three-axis moving device 3, a hook delivery device 46, a flipping device 42, a feeding platen 43, and a gripping and releasing device 45. The three-axis moving device 3 is mounted on an injection molding machine and located on one side of the stationary mold. The three-axis moving device 3 is used for movement along the X-axis 31, Y-axis 32, and Z-axis 33. The bottom of the Z-axis 33 is connected to the feeding platen 43 via the flipping device 42. The gripping and releasing device 45 is mounted on the feeding platen 43. The hook delivery device 46 is located on one side of the injection molding machine and is used to sequentially deliver hooks 92. The three-axis moving device 3 is used to drive the gripping and releasing device 45 to move between the hook delivery device 46 and the mold so that the gripping and releasing device 45 grips the hooks 92 on the hook delivery device 46 via the flipping device 42 and inserts the hooks 92 into the mold.

[0023] The three-axis moving device 3 enables the gripping and unloading device 45 to switch between the feeding station and the loading station. The gripping and unloading device 45 enables the gripping and releasing of the locking hook 92. Together, they achieve automatic loading of the locking hook 92 without the need for manual loading, which can improve loading efficiency, reduce labor intensity, and provide a guarantee for the realization of automatic injection molding function.

[0024] The three-axis motion device 3 is an existing mature product and will not be described in detail here.

[0025] The hook delivery device 46 includes a disc vibrating feeder 461, a second vibrator 464, and a second delivery guide rail 463. The disc vibrating feeder 461 is equipped with a second feeding arm 4611, and a second feeding trough 4612 is mounted on the second feeding arm 4611. The second feeding trough 4612 is used to sequentially deliver the hooks 92. The second vibrator 464 is located on one side of the disc vibrating feeder 461, and the second delivery guide rail 463 is mounted on the top of the second vibrator 464. One end of the second delivery guide rail 463 is located at one end of the second feeding arm 4611, and a second delivery slot 4631 is provided along the length of the top of the second delivery guide rail 463. The second delivery slot 4631 and the second feeding trough 4612 are coaxially aligned and communicate with each other. The disc vibrating feeder 461 is an existing, mature product. First, the locking hooks 92 are arranged sequentially by the disc vibrating feeder 461 and then fed out through the second feeding trough 4612. Then, the locking hooks 92 are moved to the end of the second feeding trough 4631 by the second vibrator 464.

[0026] To facilitate the processing of the second feed groove 4631, the hook feeding device 46 also includes a second baffle plate 465, which is fixed to the end of the second feed groove 4631 by screws and is used to position the hook 92.

[0027] To prevent the disc vibrating feeder 461 and the second vibrator 464 from operating continuously and to reduce energy consumption, the hook delivery device 46 also includes a second sensor 466. The second sensor 466 is mounted on the second baffle plate 465 and is positioned opposite to the second delivery slot 4631. The second sensor 466 can be a photoelectric sensor. The second sensor 466 is used to detect the hook 92 in the second delivery slot 4631. When the hook 92 is detected, a signal is sent to stop the disc vibrating feeder 461 and the second vibrator 464 from operating. When the hook 92 is not detected, the disc vibrating feeder 461 and the second vibrator 464 are started.

[0028] The flipping device 42 is used to flip the loading platen 43, which in turn drives the gripping and unloading device 45, from a vertical state to a horizontal state. Specifically, the flipping device 42 includes a flipping cylinder, also known as a 90-degree rack and pinion side-positioning cylinder, used to flip the workpiece by 90 degrees. The flipping cylinder is fixed to the bottom of the Z-axis 33 of the three-axis moving device 3, and the turntable of the flipping cylinder is connected to the loading platen 43. The flipping cylinder rotates at an angle of 90 degrees. When the flipping cylinder is in its initial position, the loading platen 43 is in a vertical state, and the loading platen 43 is positioned opposite the mold, allowing the locking hook 92 to be inserted into the mold. After the flipping cylinder rotates 90 degrees, the loading platen 43 is in a horizontal state, and the gripping and unloading device 45 is positioned above the second feed slot 4631 and opposite to the second loading slot, so as to grip the locking hook 92 from the second loading slot. This avoids interference between the gripping and unloading device 45 and the second feed guide rail 463 when the loading platen 43 is in a vertical state, providing stability and reliability for loading.

[0029] The material handling device 45 includes a material handling cylinder 451, a material handling seat 452, and an electromagnet 453. The material handling cylinder 451 is a dual-axis cylinder capable of high-precision feeding. The material handling cylinder 451 is fixed to the loading base plate 43. The material handling fixing plate of the material handling cylinder 451 is connected to the material handling seat 452. The top of the material handling seat 452 is provided with a second material handling groove 4522, which matches the locking hook 92. The electromagnet 453 is installed inside the material handling seat 452 and located below the second material handling groove 4522, used to magnetically attract the locking hook 92 into the second material handling groove 4522. The material handling seat 452 is made of engineering plastic, which does not affect the operation of the electromagnet 453. To facilitate the machining of the gripping and releasing base 452, the gripping and releasing base 452 includes a gripping and releasing base 4526 and a gripping and releasing platform 4521. One end of the gripping and releasing base 4526 is mounted on the gripping and releasing fixing plate of the gripping and releasing cylinder 451, and the other end of the gripping and releasing base 4526 is connected to the bottom of the gripping and releasing platform 4521. The bottom of the gripping and releasing platform 4521 is provided with two second mounting slots 4523, and the top of the gripping and releasing platform 4521 is provided with two second gripping and releasing grooves 4522, and the second gripping and releasing grooves 4522 are located directly above the second mounting slots 4523. The electromagnet 453 is installed in the second mounting slot 4523. The gripping and releasing platform 4521 facilitates the machining of the second mounting slots 4523 and makes it easy to fix the electromagnet 453. To facilitate heat dissipation of the electromagnet 453, symmetrical second heat dissipation grooves 4524 are provided on both sides of the top of the gripping and unloading platform 4521. The second heat dissipation grooves 4524 communicate with the second mounting groove 4523, allowing the side of the electromagnet 453 to be located outside the second mounting groove 4523 and in direct contact with the external environment for effective heat dissipation. To facilitate the positioning of the gripping and unloading platform 4521, a second positioning groove 4525 is provided at one end of the gripping and unloading platform 4521. The second positioning groove 4525 matches the gripping and unloading base 4526, and the second positioning groove 4525 is inserted into the gripping and unloading base 4526 to achieve precise positioning and facilitate installation.

[0030] When the hook 92 is being fed, the disc vibrator first feeds the hook 92 sequentially into the second feed slot 4631 of the second feed guide rail 463. The second vibrator 464 then moves the hook 92 into the second feeding slot. The three-axis moving device 3 moves the gripping and releasing cylinder 451 above the second feed guide rail 463. Then, the tilting cylinder rotates the feeding plate 43 from a vertical to a horizontal position, and the gripping and releasing cylinder 451 changes from a horizontal to a vertical position. The gripping and releasing platform 4521 is positioned above the second feed guide rail 463. The three-axis moving device 3 then aligns the second gripping and releasing slot 4522 with the hook 92 in the second feed slot 4631. The gripping and releasing platform 4521 then descends above the hook 92, allowing the hook 92 to enter the second gripping and releasing slot 4522. Next, the electromagnet 453 is activated, and it magnetically attracts the hook 92 into the second gripping and releasing slot 4522. Within 22, the three-axis moving device 3 moves the loading plate 43 upward to the flipping height and activates the flipping cylinder to restore the loading plate 43 from a horizontal state to a vertical state. The gripping and releasing cylinder 451 flips to a horizontal state. The three-axis moving device 3 moves the gripping and releasing cylinder 451 to one side of the mold cavity and aligns the locking hook 92 with the first insert groove in the cavity. Then, the three-axis moving device 3 moves the locking hook 92 into the first insert groove. Then, the electromagnet 453 is turned off, and the locking hook 92 is attracted into the first insert groove under the action of the magnet in the first insert groove, completing the installation of the locking hook 92. Then, the three-axis moving locking hook 92 moves the loading plate 43 and the gripping and releasing cylinder 451 to the top of the second delivery guide rail 463 to continue gripping material, preparing for the installation of the next locking hook 92. After the seat is removed, the locking hook 92 can be installed, shortening the waiting time and improving the overall efficiency of injection molding.
