Description

Technical Field

[0001] This application relates to the field of loudspeaker manufacturing technology, specifically to a multi-claw self-pressurizing internal magnet loudspeaker glue injection turntable positioning device. Background Technology

[0002] In traditional encapsulation processes for internal magnet loudspeakers, specialized positioning fixtures are typically used to fix components such as the U-shaped iron of the loudspeaker. However, existing technologies have the following drawbacks:

[0003] Poor versatility: Different sizes of U-shaped irons require different tooling, leading to frequent tooling changes and extending the production cycle;

[0004] High cost: A large amount of specialized tooling needs to be stocked, increasing inventory and management costs;

[0005] Complex operation: The clamping mechanism requires manual adjustment or relies on external power, resulting in low efficiency. Utility Model Content

[0006] The main technical problem addressed in this application is to provide a multi-claw self-pressurizing internal magnetic loudspeaker glue injection turntable positioning device.

[0007] This application discloses a multi-claw self-pressurizing internal magnetic loudspeaker glue injection turntable positioning device, comprising:

[0008] Turntable, magnets, and multiple chucks;

[0009] The turntable has a support surface for supporting the internal magnetic speaker assembly;

[0010] The magnet is embedded below the support surface of the turntable;

[0011] The chuck includes a triggering part at the lower end and a clamping part at the upper end. The chuck is rotatably mounted on the turntable via a bearing and a rotating shaft. In the free state, the triggering part of the chuck is higher than the supporting surface.

[0012] When the internal magnetic speaker assembly is placed on the support surface of the turntable, the internal magnetic speaker assembly pushes the trigger part of the claw under the action of its own gravity and the attraction force of the magnet, causing the claw to rotate around the rotation axis, so that the clamping part of the claw clamps the internal magnetic speaker assembly.

[0013] In some alternative implementations, it further includes a connecting shaft disposed at the bottom of the turntable for connecting a dispensing device.

[0014] In some alternative implementations, the rotation plane of the chuck is perpendicular to the support surface of the turntable.

[0015] In some alternative implementations, in a top-down view, the plurality of said claws are evenly distributed circumferentially on the turntable.

[0016] In some alternative implementations, the number of the claws is not less than 2 and not more than 10.

[0017] In some alternative embodiments, the clamping portion is V-shaped or hook-shaped.

[0018] In some alternative embodiments, the support surface is provided with a mounting groove for accommodating the claw and a keyway that extends vertically through the mounting groove, and the rotating shaft is fixed in the keyway.

[0019] In some alternative embodiments, the magnets are multiple and arranged in a ring array.

[0020] In some alternative implementations, the plurality of said claws are specifically used to clamp the U-shaped iron of the internal magnetic speaker assembly.

[0021] In some alternative implementations, the plurality of said claws form a circular clamping surface.

[0022] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0023] High versatility: Through multi-jaw adaptive clamping, it can be adapted to internal magnetic speaker assemblies of different sizes, reducing the frequency of tooling changes;

[0024] No external power required: clamping is achieved using its own weight and magnetic attraction, making it easy to operate and energy-saving;

[0025] Cost optimization: Reduce tooling development and inventory costs, and shorten new product development cycles;

[0026] High stability: The magnets and multiple claws work together to ensure that the components do not shift during the glue injection process.

[0027] In summary, the device of this application is a positioning device capable of adaptively clamping internal magnetic speaker assemblies of different sizes, which is easy to operate and requires no additional power. It achieves adaptive clamping and release of the internal magnetic speaker assembly, improving versatility and simplifying the operation process. The device of this application can be widely used in processes such as glue injection and assembly in the production of internal magnetic speakers, and is especially suitable for flexible production scenarios with multiple varieties and small batches, significantly improving production efficiency and equipment utilization.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0035] The following detailed descriptions will be provided through specific embodiments.

[0036] refer to Figures 1 to 4 This application provides a positioning device for a multi-claw self-pressurizing internal magnetic loudspeaker glue injection turntable (hereinafter referred to as the positioning device or apparatus), which includes:

[0037] Turntable 10, magnet 20 and multiple chucks 30;

[0038] The turntable 10 has a support surface 11 for supporting the internal magnetic speaker assembly;

[0039] Magnet 20 is embedded below the support surface 11 of turntable 10;

[0040] The chuck 30 includes a trigger part 31 located at the lower end and a clamping part 32 located at the upper end. The chuck 30 is rotatably mounted on the turntable 10 via a bearing 33 and a rotating shaft 34. In the free state, the trigger part 31 of the chuck is higher than the support surface 11.

[0041] When the internal magnetic speaker assembly is placed on the support surface 11 of the turntable 10, the internal magnetic speaker assembly pushes the trigger part 31 of the claw 30 under the action of its own gravity and the attraction force of the magnet 20, causing the claw 30 to rotate around the rotation axis 34, so that the clamping part 32 of the claw 30 clamps the internal magnetic speaker assembly.

[0042] In some alternative embodiments, the apparatus of this application further includes a connecting shaft 40, disposed at the bottom of the turntable 10, for connecting to the dispensing equipment. Unfortunately, the connecting shaft 40 and the turntable 10 are integrally formed. Driven by the dispensing equipment, the connecting shaft 40 can rotate the entire apparatus to perform the dispensing operation.

[0043] In some alternative embodiments, the rotation plane of the chuck 30 is perpendicular to the support surface 11 of the turntable 10. For example, the support surface 11 is a horizontal plane, and the rotation plane of the chuck 30 is a vertical plane.

[0044] In some alternative embodiments, in a top-down view, a plurality of grippers 30 are evenly distributed circumferentially on the turntable. Here, the number of grippers 30 is not limited. Exemplarily, the number of grippers 30 is not less than two and not more than ten. Preferably, the number of grippers 30 is two or three.

[0045] In some alternative embodiments, the gripping portion 32 of the claw 30 is V-shaped or hook-shaped. In other alternative embodiments, the gripping portion 32 may also be other shapes.

[0046] In some alternative embodiments, the gripper 30 can change the shape of the gripping part 32 to accommodate different numbers of grippers. For example, when there are two grippers 30, the gripping part 32 can be V-shaped. Alternatively, it can be a single hook shape. The specific design can be modified according to the different shapes of the speaker.

[0047] In some alternative embodiments, the support surface 11 is provided with a mounting groove for accommodating the claw 30 and a keyway that penetrates the mounting groove vertically, and the rotating shaft 34 is fixed in the keyway.

[0048] In some alternative embodiments, the magnets 20 are multiple and arranged in a ring array. For example, there are three magnets 20 arranged in a ring array.

[0049] In some alternative implementations, the plurality of claws 30 are specifically used to clamp the U-shaped iron of the internal magnet speaker assembly.

[0050] In some alternative implementations, multiple jaws 30 form a circular clamping surface. This allows for a good fit to the shape of the U-shaped iron.

[0051] The working principle of the device in this application is as follows:

[0052] Initial state: The trigger part 31 of the chuck 30 is higher than the support surface 11, and the clamping part 32 is in the open state;

[0053] Placement component: When the inner magnetic speaker assembly is placed on the support surface 11, its own weight and the attraction force of the magnet 20 press down on the trigger part 31, driving the claw 30 to rotate around the rotation axis 34, and the clamping part 32 tightens inward to clamp the U-shaped iron of the inner magnetic speaker assembly.

[0054] Component removal: When the internal magnetic speaker assembly is lifted, gravity and magnetic attraction disappear, and the pawl 30 resets and opens, achieving automatic release.

[0055] The technical solution of this application has been described in detail above through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphasis, and for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0056] It should be understood that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and protection scope of the technical solutions of the embodiments of this application.
