[0002] The diaphragm is one of the important components of a loudspeaker. It is mainly used to make the diaphragm vibrate by changing the current, thereby making different sounds in the air and transmitting them to people.

[0003] The diaphragm consists of a dome diaphragm and a voice coil. During assembly, workers often place the voice coil in a circular groove, apply a ring of adhesive to the voice coil, and then hold the dome diaphragm close to and attach it to the voice coil. After the adhesive solidifies, the assembly of the diaphragm is completed. However, manual assembly can easily lead to misalignment between the dome diaphragm and the voice coil, making it impossible for their concentricity to meet the acceptable standard. This results in a deviation in the sound quality of the diaphragm, requiring rework and reassembly, which greatly reduces the production efficiency of the diaphragm. Utility Model Content

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-6 As shown, a diaphragm assembly fixture includes a top diaphragm 31 and a voice coil 427 disposed on the top diaphragm 31, and further includes:

[0031] The base plate 1 is provided with a reducer 22 and a turntable 3 is provided on the reducer 22. The turntable 3 has clamping grooves 32 arranged in a circular array and the diaphragm is placed in the clamping grooves 32.

[0032] Support frame 4 is set on base plate 1 and located on one side of reducer 22. Cylinder 41 is set on support frame 4. Assembly plate 44 is set on output shaft of cylinder 41. Slide rod 45 that cooperates with reducer 22 is set on assembly plate 44. Clamping blocks 441 facing the sound diaphragm are symmetrically arranged on assembly plate 44. Clamping blocks 441 are air clamps.

[0033] Material plate 42 is mounted on support frame 4, and material plate 42 is provided with material cylinder 428 that cooperates with clamping block 441. Voice coil 427 is disposed inside material cylinder 428.

[0034] Specifically, multiple sets of circular holes are provided on the base plate 1 to improve the robustness of the modified tooling and make the output of the support frame 4 and the reducer 22 more stable. The reducer 22 has a worm gear drive inside, with a linkage at one end of the worm and a motor 21 at the other end. The motor 21 controls the rotation of the assembly plate 44 around the axis of the cylinder 41 or the rotation of the turntable 3. The turntable 3 is fixed to the output shaft of the worm gear through the connecting plate 24. An axis is set at the center of the turntable 3, and clamping grooves 32 are evenly distributed on the turntable 3 with the axis as a reference. The top diaphragm 31 is positioned by the clamping grooves 32. During the diaphragm assembly process, the top diaphragm 31 is placed in the clamping grooves 32. The voice coil 427 is placed inside the material cylinder 428. At this time, the reducer 22 drives the turntable 3 and the assembly plate to rotate, thereby clamping the voice coil 427 inside the material cylinder 428 directly above the diaphragm. The cylinder 41 drives the assembly plate 44 to slide downward, so that the voice coil 427 is attached to the annular rubber ring 33 on the top diaphragm 31, thus completing the assembly of the diaphragm. The subsequent assembly steps are as follows: the turntable 3 is rotated by a certain angle, and the clamping plate rotates 180° so that the voice coil 427 is directly above the top diaphragm 31 for assembly. The above assembly steps are repeated to improve the assembly efficiency of the diaphragm and reduce the error in the assembly process, so as to make the diaphragm production quality better.

[0035] As a further embodiment provided by this utility model, the reducer 22 is provided with a linkage rod 23, one end of which is provided with a second bevel gear 464. The support frame 4 is provided with a stabilizing plate 465, and the stabilizing plate 465 is provided with a driving wheel 462 and a driven wheel 466 in sequence. A synchronous belt 461 is provided between the driving wheel 462 and the driven wheel 466. The central shaft of the driving wheel 462 is provided with a first bevel gear 463 that meshes with the second bevel gear 464. The driven wheel 466 cooperates with the slide bar 45. The worm gear drives the second bevel gear 464 to rotate through the linkage rod 23, thereby making the first bevel gear 463 and the driving wheel 462 rotate synchronously. The synchronous belt 461 makes the driven wheel 466 rotate in conjunction with the slide bar 45. That is, while the turntable 3 rotates at a certain angle, the mounting plate 44 is driven to rotate 180°.

[0036] As a further embodiment of this utility model, a protective cover 43 is provided on the support frame 4, and a bearing that cooperates with the linkage rod 23 is provided on the protective cover 43. The protective cover 43 covers the second bevel gear 464 and the drive wheel 462, thereby providing them with a certain protective effect. At the same time, its bearing supports the linkage rod 23 and improves the rotation effect of the linkage rod 23.

[0037] As a further embodiment of this utility model, a telescopic rod 442 is provided on the assembly plate 44. One end of the telescopic rod 442 is provided with a first spring 443 that contacts the assembly plate 44, and the other end is provided with a clamping block 441. At least two sets of clamping blocks 441 are provided and are evenly distributed on both sides of the output shaft of the cylinder 41. When the assembly plate 44 rotates 180°, clamping block 441-1 is conveyed to the top of the material cylinder 428 (clamping block 441-1 is not clamping the voice coil 427), and clamping block 441-2 is conveyed to the top of the top diaphragm 31 (clamping block 441-2 is clamping the voice coil 427). The cylinder 41 drives the assembly plate 44 to descend. At this time, the clamping block 441 assembles the voice coil 427 onto the top diaphragm 31, while the clamping block 441 is located in the material cylinder 428 to hold the voice coil 427. The first spring 443 plays a reset role. During the assembly or clamping of the voice coil 427, the telescopic rod 442 is pushed and slides on the assembly plate 44, so that the first spring 443 is in a stretched state, which plays a certain protective role for the voice coil 427. When the assembly plate 44 rises, the clamping block 441 returns to its initial position through the first spring 443.

[0038] As a further embodiment of this utility model, a slot 446 is provided on the output shaft of the cylinder 41, and a triangular block 445 that cooperates with the slot 446 is provided on the assembly plate 44. A second spring 444 is provided between the triangular block 445 and the assembly plate 44. The slot 446 is adapted to the triangular block 445, so the slot 446 is triangular. When the cylinder 41 is pressed down, the assembly plate 44 moves downward by cooperating with the slot 446 through the triangular block 445. When the assembly plate 44 rotates, the setting of the triangular block 445 does not restrict the rotation of the assembly plate 44.

[0039] As a further embodiment of this utility model, the material cylinder 428 has a push channel, in which a top plate 425 is slidably disposed. The voice coil 427 is stacked on the top plate 425. A motor 426 is disposed on the material cylinder 428. A transmission rod 424 cooperating with the top plate 425 is disposed on the output shaft of the motor 426. The transmission rod 424 is a screw, and the top plate 425 is threadedly engaged with the transmission rod 424. The transmission rod 424 is driven to rotate by the motor 426 to control the top plate 425 to slide upward in the push channel, so as to push the voice coil 427 to a certain position, thereby facilitating the clamping of the clamping block 441.

[0040] As a further embodiment of this utility model, the material cylinder 428 is provided with a threaded portion, which cooperates with the material plate 42. When a voice coil 427 of a different specification is replaced, the material cylinder 428 can be removed and replaced to fit the size of the voice coil 427.

[0041] As a further embodiment of this utility model, a guide sleeve 421 is provided on the material plate 42. Bearings are provided at both ends of the guide sleeve 421. The guide sleeve 421 improves the support effect on the slide rod 45 and also guides the slide rod 45 to slide axially.

[0042] As a further embodiment of this utility model, a fixing block 35 is provided in the clamping groove 32, and a limiting plate 34 is snapped onto the fixing block 35. The top film 31 is snapped onto the limiting plate 34. The fixing block 35 is fixed to the clamping groove 32 by bolts. The number of clamping grooves 32 and fixing blocks 35 is the same. The limiting plate 34 is adapted to the top film 31. When changing to a different specification of top film 31, the limiting plate 34 can be removed and replaced.

[0043] As a further embodiment provided in this utility model, an observation window is provided on the support frame 4, the observation window as follows: Figure 4 As shown, the clamping status of the clamping block 441 and the sliding distance of the assembly plate 44 can be observed through the observation window, which facilitates the early debugging of the tooling.
