[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] As shown in the figure, an automatic loading and unloading forming device for electric horn diaphragms includes a frame 1, on which an upper mold and a lower mold 3 are provided. A loading rod 4 and a unloading rod 5 are vertically and symmetrically located on both sides of the lower mold 3. A loading linear module 6 and a unloading linear module 7 are vertically and symmetrically located on both sides of the lower mold 3. A loading lifting plate 8 and a unloading lifting plate 9 are fixedly mounted on the sliding seats of the loading linear module 6 and the unloading linear module 7, respectively. A loading cylinder 10 and a unloading cylinder 11 with their output shafts facing the lower mold 3 are respectively mounted on the loading lifting plate 8 and the unloading lifting plate 9. A loading arm 12 and a unloading arm 13 are fixedly connected to the output shafts of the loading cylinder 10 and the unloading cylinder 11, respectively. A loading suction cup 14 and a unloading suction cup 15 are respectively mounted on the loading arm 12 and the unloading arm 13.

[0021] In the above structure, the feeding rod 4 passes through the mounting hole of the film to be formed, stacking the film onto the feeding rod 4. The feeding linear module 6 and the unloading linear module 7 can respectively drive the feeding lifting plate 8, feeding cylinder 10, feeding arm 12, feeding suction cup 14, and unloading lifting plate 9, unloading cylinder 11, unloading arm 13, and unloading suction cup 15 to move longitudinally. The feeding cylinder 10 and the unloading cylinder 11 can respectively drive the feeding arm 12, feeding suction cup 14, and unloading arm 13 and unloading suction cup 15 to move horizontally. When performing the film forming operation, the feeding operation is as follows: The feeding cylinder 10 drives the feeding arm 12, which in turn moves the feeding suction cup 14 horizontally above the film to be formed. The feeding linear module 6 moves the feeding suction cup 14 downward to contact and hold the film to be formed. The feeding suction cup 14, holding the film to be formed, moves upward and away from the feeding rod 4. The feeding cylinder 10 moves the feeding suction cup 14 horizontally between the upper mold and the lower mold 3. The feeding linear module 6 moves the feeding suction cup 14 downward so that the film to be formed is placed on the upper surface of the lower mold 3. The loading operation is completed by releasing the film to be formed, leaving it on the upper surface of the lower mold 3. After the upper mold 2 moves to the lower mold 3 to cooperate with the lower mold 3 to complete the forming operation of the film, the unloading operation is as follows: the unloading cylinder 11 drives the unloading suction cup 15 horizontally to the space between the upper mold and the lower mold 3 via the unloading arm 13. The unloading linear module 7 drives the unloading suction cup 15 downward to pick up the formed film. The unloading suction cup 15 drives the formed film upward to move away from the upper surface of the lower mold 3. The unloading cylinder 11 drives the unloading suction cup 15 to carry out the forming operation. The diaphragm moves horizontally above the feeding rod 5, aligning the mounting hole of the formed diaphragm with the feeding rod 5. The feeding linear module 7 drives the feeding suction cup 15, which in turn moves the formed diaphragm downward, allowing the feeding rod 5 to pass into the mounting hole of the formed diaphragm. After the feeding suction cup 15 releases the formed diaphragm, the formed diaphragms are stacked on the feeding rod 5, thus completing the feeding operation. Through the above structure and method, this automatic feeding and unloading forming equipment for electric horn diaphragms can automatically complete the feeding operation before forming and the unloading operation after forming, thereby improving the efficiency of the diaphragm forming operation.

[0022] Furthermore, based on the above structure, the frame 1 is provided with an upper feeding transition rod 16 and an lower feeding transition rod 17 located between the upper feeding rod 4 and the lower die 3, and between the lower feeding rod 5 and the lower die 3, respectively. The center of the upper feeding transition rod 16 is horizontally equidistant from the center of the upper feeding rod 4 and the center of the lower die 3. The center of the lower feeding transition rod 17 is horizontally equidistant from the center of the lower feeding rod 5 and the center of the lower die 3. The upper end faces of the upper feeding transition rod 16 and the lower feeding transition rod 17 are flush with the upper end face of the lower die 3. The upper surfaces of the flat feeding transition rod 16 and the unloading transition rod 17 are respectively fixed with feeding positioning posts and unloading positioning posts. Two sets of feeding suction cups 14 and unloading suction cups 15 are respectively installed on the feeding arm 12 and the unloading arm 13. The frame 1 is equipped with a lifting electric cylinder 23 located on one side of the feeding rod 4 with its output shaft facing upwards. During the feeding operation, when one set of feeding suction cups 14 is above the feeding rod 4, the other set of unloading suction cups 15 is above the feeding transition rod 16. Figure 2 As shown, when the left set of feeding suction cups 14 picks up the film to be formed on the feeding rod 4, the right set of feeding suction cups 14 places the film to be formed on the feeding transition rod 16, and retains the film to be formed on the feeding transition rod 16 by passing the feeding positioning pin through the mounting hole of the film to be formed. When the right set of feeding suction cups 14 feeds the film to be formed onto the lower mold 3, the left set of feeding suction cups 14 transfers the film to be formed onto the feeding transition rod 16. By temporarily retaining the film to be formed on the feeding transition rod 16, the horizontal distance that the feeding suction cups 14 need to move when the film to be formed is fed from the feeding rod 4 to the lower mold 3 is shortened, thereby improving the feeding speed and ensuring the stability during feeding. During the feeding process, the output shaft of the lifting cylinder 23 is located below the film to be formed stacked on the feeding rod 4. As the number of film to be formed on the feeding rod 4 gradually decreases, the output shaft of the lifting cylinder 23 gradually rises and lifts the film to be formed on the feeding rod 4, ensuring that the feeding suction cups 14 on the left side can contact the film to be formed and hold it for feeding. Similarly, during the unloading process, the unloading transition rod 17, together with two sets of unloading suction cups 15, can also temporarily retain the unloaded film, shortening the horizontal distance that the unloading suction cups 15 need to move when the unloaded film is unloaded from the lower mold 3 to the unloading rod 5. This will not be described in detail here, thereby improving the unloading efficiency.

[0023] Furthermore, based on the above structure, each set of feeding suction cups 14 and discharging suction cups 15 includes at least two feeding suction cups 14 and discharging suction cups 15. The multiple feeding suction cups 14 and discharging suction cups 15 in each set of feeding suction cups 14 and each set of discharging suction cups 15 enhance the stability when holding the film to be formed and the formed film by increasing the number of contact points, thereby ensuring the stability of feeding and discharging.

[0024] Furthermore, based on the above structure, the frame 1 is provided with a feeding indexing plate 18 and a discharging indexing plate 19 located on both sides of the lower mold 3. Several feeding rods 4 and discharging rods 5 are arranged in a circular array on the feeding indexing plate 18 and the discharging indexing plate 19, respectively. The feeding indexing plate 18 and the discharging indexing plate 19 drive the rotation of several feeding rods 4 and several discharging rods 5 to achieve position switching. This allows the feeding rods 4 and discharging rods 5 in different positions to rotate to positions that cooperate with the feeding suction cup 14 and the discharging suction cup 15, thereby increasing the number of continuous feeding and discharging operations. It eliminates the need for frequent operations of stacking the film to be formed on the feeding rod 4 or unloading the formed film from the discharging rod 5, thereby improving the efficiency of the electric horn film forming operation.

[0025] In addition, based on the above structure, a forming positioning post 31 is fixedly provided on the upper end surface of the lower mold 3. When the film to be formed is fed to the upper end surface of the lower mold 3, the forming positioning hole passes through the installation hole of the film and plays a positioning role on the position of the film on the lower mold 3, thereby enhancing the accuracy of the forming operation when the upper mold and the lower mold 3 cooperate.

[0026] Furthermore, based on the above structure, the frame 1 is equipped with a feeding sensor 20 and a discharging sensor 21 located on one side of the feeding rod 4 and the discharging rod 5, respectively. The feeding sensor 20 and the discharging sensor 21 monitor the number of films to be formed leaving the feeding rod 4 and the number of films to be formed placed on the discharging rod 5, respectively. This allows the feeding sensor 20 and the discharging sensor 21 to achieve more precise position switching of the feeding rod 4 and the discharging rod 5 with the feeding indexing plate 18 and the discharging indexing plate 19, thereby improving the automation level of the equipment.

[0027] In addition, based on the above structure, the frame 1 is equipped with a monitoring sensor 22 located on one side of the upper film 2. The monitoring sensor 22 is used to monitor the position of the upper film 2. The monitoring sensor 22, in cooperation with the feeding cylinder 10 and the unloading cylinder 11, ensures that the feeding suction cup 14 and the unloading suction cup 15 can extend between the upper mold and the lower mold 3 after the mold is opened, thereby improving the automation level of the equipment.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
