[0025] As shown in Figure 4As shown, the front and rear walls of the feeding plate 12 are respectively fixedly provided with sliding bars 13 movably installed in the sliding grooves 9, the right side of the top surface of the feeding plate 12 is provided with a material taking groove 14 corresponding to the material placing cavity 11, the bottom surface of the feeding plate 12 is fixedly provided with a connecting plate 15 penetrating through the limiting movable opening 5, the first linear cylinder 16 is fixedly installed on the outer side wall of the cylinder seat 6, and the output end of the first linear cylinder 16 is fixedly installed with the connecting plate 15, after the output end of the first linear cylinder 16 is driven to push the connecting plate 15 to move in the limiting movable opening 5, the feeding plate 12 will move to the right between the guide plates 8, and the sliding bars 13 slide in the sliding grooves 9, thus the feeding plate 12 can take out the speaker diaphragm at the bottom end of the speaker diaphragms stacked in the material placing cavity 11 each time, and the feeding plate 12 can support the speaker diaphragm in the material placing cavity 11 to prevent it from moving downward continuously;

[0026] As Figure 5 shown, the right side of the top surface of the workbench 1 is provided with a through opening 7, the through opening 7 ensures that the output end of the rotary cylinder 17 can normally realize rotation operation, the bottom surface of the workbench 1 is fixedly provided with the rotary cylinder 17 below the through opening 7, the bottom end of the rotary column 18 is fixedly provided with a connecting seat 19, the connecting seat 19 is fixedly installed on the output end of the rotary cylinder 17, the rotary plate 20 is fixedly installed on the top end of the rotary column 18, the left side of the top surface of the rotary plate 20 is fixedly provided with a second linear cylinder 21, the output end of the second linear cylinder 21 is fixedly provided with a vacuum chuck 22 at the bottom end, after the output end of the second linear cylinder 21 is driven to push the vacuum chuck 22, the vacuum chuck 22 can suck the speaker diaphragm in the material taking groove 14, after sucking, the rotary cylinder 17 is opened to drive the rotary column 18 to rotate one hundred and eighty degrees through the connecting seat 19, the rotary plate 20 at the top end of the rotary column 18 will drive the speaker diaphragm to rotate one hundred and eighty degrees and then move above the next station, after the second linear cylinder 21 pushes the vacuum chuck 22 to make the diaphragm enter the station, the vacuum chuck 22 no longer sucks the speaker diaphragm, and the automatic feeding operation is completed.

[0027] The specific feeding process of replacing manual feeding by the cooperation of the feeding mechanism 2 and the material moving mechanism 3 is as follows:

[0028] The speaker diaphragm to be fed is placed in advance from the top end of the stacking bin 10 into the discharging cavity 11 opened in the stacking bin 10, so that the speaker diaphragms are stacked in the stacking bin 10. At this time, the speaker diaphragm at the bottom end of the stacking in the discharging cavity 11 will fall into the corresponding speaker diaphragm taking groove 14 opened on the top surface of the feeding plate 12 right side at the bottom end of the stacking bin 10 under the action of gravity. When feeding, the first linear cylinder 16 installed on the outer side wall of the cylinder seat 6 is opened, and the first linear cylinder 16 will drive the output end to push the connecting plate 15 installed together to move in the limiting movable opening 5 opened on the top surface of the workbench 1 to the right side direction. The connecting plate 15 will drive the feeding plate 12 installed on the top surface to move synchronously to the right side direction between the symmetrical guide plates 8 installed on the top surface of the workbench 1. When moving, the sliding strips 13 installed on both sides of the feeding plate 12 will slide in the sliding grooves 9 opened on the opposite side walls of the symmetrical guide plates 8, until the speaker diaphragm in the taking groove 14 moves from the bottom end of the stacking bin 10 to the bottom end right side of the stacking bin 10. When the taking groove 14 moves from the bottom end of the stacking bin 10 to the right side, the left side part of the feeding plate 12 gradually moves to the bottom end of the stacking bin 10 to support and block the speaker diaphragms stacked in the discharging cavity 11. Therefore, the speaker diaphragm at the bottom end of the stacking in the discharging cavity 11 can be pushed to feed at one time. At this time, the second linear cylinder 21 installed on the top surface left side of the rotating plate 20 will drive the output end to push the vacuum suction cup 22 downward, so that the vacuum suction cup 22 contacts the speaker diaphragm in the taking groove 14. After that, the vacuum suction cup 22 will suck the speaker diaphragm in the taking groove 14. After sucking, the second linear cylinder 21 drives the output end to drive the vacuum suction cup 22 to move upward, so that the speaker diaphragm moves out of the taking groove 14. After moving out, the rotating cylinder 17 installed at the bottom of the workbench 1 will drive the output end to rotate in the through opening 7 opened on the top surface of the workbench 1. Because the rotating column 18 is installed together with the output end of the rotating cylinder 17 through the connecting seat 19 at the bottom end, the output end of the rotating cylinder 17 will drive the rotating column 18 to rotate one hundred and eighty degrees through the connecting seat 19. The rotating column 18 will drive the rotating plate 20 to rotate one hundred and eighty degrees, and make the rotating plate 20 rotate from the left side transverse part to the right side transverse part, so that the speaker diaphragm is placed directly above the next station. The second linear cylinder 21 will again drive the output end to move the vacuum suction cup 22 downward, so that the speaker diaphragm sucked by the vacuum suction cup 22 enters the station, and the suction of the speaker diaphragm is cancelled. The second linear cylinder 21 drives the vacuum suction cup 22 to move upward to the original position. After the moving mechanism 3 completes the suction and taking of the speaker diaphragm in the taking groove 14, the first linear cylinder 16 will drive the feeding plate 12 to the original position through the connecting plate 15. At this time, the left side part of the feeding plate 12 no longer blocks the opening of the discharging cavity 11 at the bottom end of the stacking bin 10, so that the speaker diaphragm at the bottom end in the discharging cavity 11 will automatically fall into the taking groove 14. Then, the feeding mechanism 2 pushes the speaker diaphragm to the right side to wait for the taking and feeding of the moving mechanism 3.The material moving mechanism 3 completes the taking and placing of the last loudspeaker diaphragm, and then returns to the original position to take the loudspeaker diaphragm in the taking groove 14 of the feeding mechanism 2, rotates and then feeds, and the above operation is repeated to continuously and automatically feed, which can replace the manual feeding mode, the feeding operation is simple and fast, the equipment structure is simple and easy to maintain, time and labor are saved, the labor intensity of workers is reduced, and the production efficiency is improved.

[0029] The above is only the preferred embodiment of the present application, and is not used to limit the present application. Although the present application is described in detail with reference to the foregoing embodiment, various improvements can be made to the present application without departing from the scope of the present application, equivalent replacements can be made to the components, or equivalent replacements can be made to part of the technical features, and all of the above should be included in the protection scope of the present application.
