Technical Field

[0001] The utility model relates to the technical field of multi-speaker sound film processing, in particular to a speaker sound film combination structure. Background Technique

[0002] The sound film is a diaphragm for the playback of the speaker. In the horn speaker and the dome speaker, for the convenience of assembly, the dome film and the voice coil are often bonded together to form a component, which we call the sound film. When combining the sound film and the voice coil, a sound film combination structure is needed for operation.

[0003] In the prior art, in the current sound film combination, the sound film is placed at the processing position of the combination structure, and the voice coil is placed above the sound film. Then, through the glue injection mechanism in the combination structure, glue is injected into the connection between the sound film and the voice coil. Since most of the current sound films are only stabilized by the simple positioning grooves or positioning rods at the processing position of the combination structure during placement, the stability of the sound film during the combination of the sound film is poor, resulting in the displacement of the position between the sound film and the voice coil, affecting the quality of the combined sound film. Content of the Utility Model

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: including: an operation frame, one side of the operation frame is fixedly connected with one side of the glue injection frame, the side of the operation frame perpendicular to the glue injection frame is fixedly connected with one side of the workbench, the top end of the workbench is fixedly connected with the bottom end of the stability mechanism, the stability mechanism includes a fixed frame, an arc-shaped groove, a movable groove, a moving groove, an ejecting spring, an ejecting rod, a sliding groove, a limiting groove, a pressing rod and a limiting block, the outer wall of the stability mechanism is movably connected with the inner wall of the limiting mechanism, and the limiting mechanism includes a moving ring, a stabilizing plate, a connecting spring, a pressing groove, a receiving groove, a reset spring, a moving block, a clamping block, a connecting plate and an arc-shaped pressing block.

[0006] As a preferred implementation manner, the bottom end of the fixed frame is fixedly connected with the top end of the workbench, and the fixed frame is located at the bottom of the glue outlet of the glue injection frame. An arc-shaped groove is opened on the outer wall of the top of the fixed frame, and movable grooves are opened on both sides of the fixed frame.

[0007] As a preferred embodiment, a moving groove is formed inside the fixing frame, and the bottom wall of the moving groove is fixedly connected to the bottom end of the ejecting spring. The top end of the ejecting spring is fixedly connected to the bottom end of the ejecting rod, and the bottom of the ejecting rod is tapered.

[0008] As a preferred embodiment, sliding grooves are formed on two sides of the moving groove perpendicular to the movable groove, and a limiting groove is formed at the top of the sliding groove. The outer wall of the pressing rod is movably connected to the inner wall of the sliding groove, and the top end of the pressing rod is fixedly connected to the bottom end of the limiting block. The outer wall of the limiting block is movably connected to the inner wall of the limiting groove. One side of the pressing rod close to the ejecting rod is an inclined surface, and one side of the pressing rod away from the ejecting rod is an arc surface.

[0009] As a preferred embodiment, the inner wall of the moving ring is movably connected to the outer wall of the fixing frame, and the inner wall of the moving ring is fixedly connected to one side of the stabilizing plate. The bottom end of the stabilizing plate is fixedly connected to the top end of the connecting spring, and the outer wall of the stabilizing plate is movably connected to the inner wall of the movable groove.

[0010] As a preferred embodiment, pressing grooves are formed inside both sides of the moving ring perpendicular to the stabilizing plate, and a receiving groove is formed at one side of the top of the pressing groove. One end of a reset spring is fixedly connected to the inner side wall of the pressing groove.

[0011] As a preferred embodiment, the other end of the reset spring is fixedly connected to one side of the moving block, and one side of the moving block away from the reset spring is fixedly connected to one side of the clamping block. The outer wall of the clamping block is movably connected to the inner wall of the receiving groove.

[0012] As a preferred embodiment, the bottom end of the moving block is fixedly connected to the top end of the connecting plate, and one side of the connecting plate close to the connecting plate is fixedly connected to one side of the arc-shaped pressing block.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In this utility model, when the moving ring is pulled downward, the moving ring moves through the stabilizing plate. The movement of the stabilizing plate squeezes the connecting spring. As the moving ring moves downward, it drives the arc-shaped extrusion block to move. The arc-shaped extrusion block moves away from the stabilizing plate, and then the fixing frame squeezes the arc-shaped extrusion block. The arc-shaped extrusion block drives the connecting plate and the moving block to move under the extrusion. The movement of the moving block squeezes the return spring. At the same time, the clamping block moves into the internal storage groove along with the moving block. Place the sound film workpiece above the fixing frame, with the workpiece located between the clamping blocks. Release the moving ring, and the return of the connecting spring drives the moving ring to move upward. The arc-shaped extrusion block is no longer squeezed by the outer wall of the fixing frame. The return of the return spring drives the clamping block to squeeze the outer wall of the workpiece, thereby clamping the workpiece stably, facilitating the stabilization of the workpiece and avoiding the phenomenon of workpiece position deviation.

[0015] 2. In this utility model, when the moving ring is pulled downward, the fixing frame squeezes the arc-shaped extrusion block, causing the clamping block to enter the internal storage groove. As the moving ring continues to move downward, the inner wall of the moving ring squeezes the arc surface of the extrusion rod. Due to the limitation of the limiting block, the inclined surface at one end of the extrusion rod squeezes the inclined surface of the ejector rod, thereby driving the ejector rod to move upward and stretching the ejector spring at the same time. The upward movement of the ejector rod jacks up the workpiece, facilitating the worker to take out the combined sound film. BRIEF DESCRIPTION OF THE DRAWINGS

The inner side wall of the pressing groove 504 is fixedly connected to one end of the return spring 506.

[0035] Specifically: The movement of the moving block 507 and the accommodation of the clamping block 508 are facilitated by the pressing groove 504 and the receiving groove 505.

The moving block 507 moves to squeeze the reset spring 506. At the same time, the clamping block 508 moves into the storage groove 505 along with the moving block 507. Place the voice coil membrane workpiece above the fixing frame 401, and the workpiece is located between the clamping blocks 508. Release the moving ring 501. The reset of the connecting spring 503 drives the moving ring 501 to move upward. The arc-shaped pressing block 510 is not extruded by the outer wall of the fixing frame 401. The reset of the reset spring 506 drives the clamping block 508 to squeeze the outer wall of the workpiece, thereby clamping the workpiece stably. Perform glue injection operation through the workbench 3, and then complete the combination of the voice coil membrane. After the combination of the voice coil membrane is completed, pull the moving ring 501 downward. The extrusion of the fixing frame 401 on the arc-shaped pressing block 510 causes the clamping block 508 to enter the storage groove 505. As the moving ring 501 continues to move downward, the inner wall of the moving ring 501 presses the arc-shaped surface of the extrusion rod 409. Limited by the limiting block 410, the inclined surface at one end of the extrusion rod 409 presses the inclined surface of the ejector rod 406, thereby driving the ejector rod 406 to move upward and stretching the ejector spring 405 at the same time. Through the upward movement of the ejector rod 406, the workpiece is jacked up.
