Description

Technical Field

[0001] The utility model relates to the technical field of speaker assembly equipment, in particular to a sound film assembly device for speaker production. Background Art

[0002] The assembly of the membrane on the speaker is a critical step in the speaker manufacturing process. During the assembly process, the membrane needs to be precisely processed and installed to ensure that it can work correctly with the other parts of the speaker.

[0003] When assembling the speaker, the film needs to be precisely positioned and glued to the voice coil and other components to ensure that it can vibrate stably and produce clear sound. Therefore, the main part of the speaker needs to be fixed on the jig, and the film needs to be placed on the main part of the speaker manually or semi-automatically, and then fixed by gluing or other fixing methods, such as the Chinese utility model patent disclosed by publication number CN204836589U: A high-fidelity headphone speaker sound membrane assembly jig, which is provided with a protrusion IV and a plurality of grooves IV on the protrusion IV. The high-fidelity headphone speaker sound membrane assembly jig provided by the application improves the assembly efficiency. During the film loading process, since the film is pre-stored in a specific storage container, the automatic loading of the film cannot be achieved during the manual assembly process. When the film is loaded by a structure such as a robotic arm, a sustainable loading mechanism cannot be provided for the robotic arm. If a conveyor belt or other structure is added for feeding, the production operation cost and the production space will increase. Utility Model Content

A distance sensor 7 is fixedly installed on one side of the Y-axis slide 6, and the X-axis slide 5, the Y-axis slide 6, and the distance sensor 7 are electrically connected to the external main controller through connecting lines respectively. A side rod 8 is fixedly installed on one side of the distance sensor 7. A suction cup 9 is fixedly installed at the bottom of the platform 6, and the suction cup 9 is connected to the air pump through an air pipe. The film pusher 3 includes two end seats 10, and a plurality of connecting plates 11 are fixedly connected between the two end seats 10. A lifting plate 12 is movably installed between the plurality of connecting plates 11, and a plurality of sliders 24 are fixedly installed on the outside of the lifting plate 12, and two clamping blocks 13 are movably installed on one side of one slider 24. A carrier plate 14 is fixedly installed on one side of the upper end seat 10, and a screw rod 15 is movably installed in the carrier plate 14. A shaft seat 16 is also fixedly installed on the carrier plate 14 on the side of the screw rod 15, and a first bevel gear 17 is movably installed on one side of the shaft seat 16.

[0027] like Figure 3 As shown, a connecting seat 19 is fixedly installed on one side of the side rod 8, and the side rod 8 is fixedly installed on one side of the distance sensor 7 through the connecting seat 19. The side rod 8 located below the connecting seat 19 is also provided with a tooth groove 20. With the help of the setting of the side rod 8, the first bevel gear 17 can be driven to rotate a certain distance when the Y-axis slide 6 moves upward.

[0028] like Figure 4-Figure 7As shown, a rotating shaft 21 is fixedly installed on one side of the first bevel gear 17, and the rotating shaft 21 is rotatably installed in the shaft seat 16. A gear 22 is fixedly installed on the side of the rotating shaft 21 away from the first bevel gear 17, and the gear 22 is meshed with the tooth groove 20. Through the arrangement of the first bevel gear 17, the rotating shaft 21, and the gear 22, the first bevel gear 17 can provide a transmission function for driving the screw rod 15 to rotate under the drive of the side rod 8. The upper end of the screw rod 15 is rotatably installed in the bearing in the carrier plate 14 and fixedly installed with the second bevel gear 23, and the second bevel gear 23 is meshed with the first bevel gear 17. A plurality of sliders 24 are slidably installed between the two connecting plates 11, and one of the sliders 24 is also provided with a connecting rod on one side. The connecting groove 25, the two clamping blocks 13 are fixedly installed with a gear ring 26 on one side close to the slider 24, and the two clamping blocks 13 are rotatably installed in the connecting groove 25 on one side through the gear ring 26, and the two gear rings 26 are meshed with each other. The two clamping blocks 13 are respectively provided with a semi-thread groove 27 on the opposite side, and the clamping blocks 13 are also fixedly installed with a magnetic block 18 near the semi-thread groove 27. One side of the two clamping blocks 13 is adsorbed and connected to each other through two magnetic blocks 18, and the two semi-thread grooves 27 are threadedly connected to the screw rod 15. The lifting plate 12 is threadedly connected to the screw rod 15 with the help of the two clamping blocks 13. After the film pusher 3 takes the material once, the sound film between the multiple carrier plates 14 can be automatically lifted to a certain distance, thereby facilitating the film pusher 3 to take the material.

[0029] It should be noted that the utility model is a sound film assembly device for speaker production. When the film for the speaker is assembled on the main body of the speaker, the main body of the speaker can be installed in the jig first and placed on the conveyor 1. At the same time, the film installation position on the speaker body is automatically glued with the help of automatic glue dispensing equipment. When the jig drives the speaker body to move to the bottom of the material-picking mechanism 2, the cooperation of the X-axis slide 5 and the Y-axis slide 6 drives the suction cup 9 to move to the position above the film pusher 3. At this time, the side rod 8 located above the tooth groove 20 abuts against one side of the gear 22. At the same time, the Y-axis slide 6 moves down in front of the X-axis slide 5, so that the suction cup 9 can adsorb the top layer of film in the film pusher 3 for material collection. Then, the Y-axis slide 6 moves up a certain distance. At this time, the Y-axis slide 6 drives the connecting seat 19 and the side rod 8 to move up synchronously through the distance sensor 7, thereby making the gear on one side of the side rod 8 The second bevel gear 23 is meshed with the second bevel gear 23 and the second bevel gear 23 is driven by the screw rod 15 to rotate a certain distance. As a result, the screw rod 15 rotates in the semi-thread groove 27 on the opposite side of the two clamping blocks 13, thereby controlling the lifting plate 12 to move up one film position between the four connecting plates 11, so that the upper layer of the film placed in the film pusher 3 is always in the same position. Then, the suction cup 9 and the Y-axis slide 6 and the gantry 4 slide in front of the gantry 4 to the position above the conveyor 1. Then, the Y-axis slide 6 drives the suction cup 9 to move down and press the film tightly on the speaker body for gluing. Subsequently, the remaining operation steps are similar to those described above.

[0030] When the film feeding in the film pusher 3 is completed, one of the clamping blocks 13 can be swung to one side, so that the magnetic blocks 18 of the two clamping blocks 13 are separated, and then the clamping block 13 rotates in the connecting groove 25 with the gear ring 26 as the axis, so that the two gear rings 26 engage with each other and drive the two clamping blocks 13 to open synchronously, so that the semi-thread groove 27 on the opposite side of the two clamping blocks 13 is separated from the screw rod 15. At this time, the lifting plate 12 can be pulled down and reset between the multiple connecting plates 11, and then the film can be stacked in the film pusher 3 again.
