Description

Technical Field

[0001] This utility model relates to the field of audio equipment manufacturing technology, and in particular to an automatic closed-loop device for applying adhesive thickness to the suspension edge of an audio system. Background Technology

[0002] The speaker is the main sound-producing component of a speaker or speaker enclosure, and the cone is one of the main components in the speaker that drives the air to vibrate and thus produce sound. The cone is mainly composed of structures such as the suspension and dust cap. The suspension mainly vibrates and is related to the elasticity of the diaphragm, which can ensure that the speaker can maintain a good sound effect during long-term playback.

[0003] In the production process of audio equipment, adhesive needs to be applied to the surround to attach it to the speaker. For example, an adhesive application device for audio equipment manufacturing (publication number CN221581029U) uses a suction cup to fix the surround and a rotating ring to drive the adhesive application component to apply adhesive to the surround. However, the size of the surround varies depending on the size of the speaker. The milled holes on the suction cup are fixed, and the relative position of the adhesive application component is also fixed, making it inconvenient to apply adhesive to surrounds of different sizes. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an automatic adhesive thickness closed-loop device for speaker suspension edges, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an automatic adhesive thickness closed-loop device for speaker suspension, comprising a base, a turntable mounted on the base, a drive motor at the bottom of the base capable of rotating the turntable, a first bidirectional drive assembly within the turntable, two first movable seats mounted on the first bidirectional drive assembly, and constraint plates mounted on the first movable seats; a vertical frame fixedly connected to the base, a second bidirectional drive assembly within the vertical frame, two second movable seats mounted on the second bidirectional drive assembly, a vertical drive assembly mounted on the second movable seats, and an adhesive application component mounted at the output end of the vertical drive assembly.

[0007] The above technical solution involves placing the speaker surround inside a turntable. Based on the speaker surround's dimensions, a first bidirectional drive assembly moves the first movable seat and constraint plate, causing the constraint plate to constrain the speaker surround from the outside. A second bidirectional drive assembly moves the second movable seat and adhesive application assembly, aligning the adhesive application assembly with the speaker surround. A drive motor is activated to rotate the turntable, which in turn rotates the speaker surround. A vertical drive assembly moves the adhesive application assembly downwards, applying adhesive to the speaker surround. The device can be adjusted according to the specific dimensions of the speaker surround, accommodating a wider range of sizes and offering greater flexibility.

[0008] Preferably, in any of the above schemes, the turntable adopts a cylindrical structure, and a number of pulleys are evenly arranged on the circumference of the bottom surface of the turntable.

[0009] The above technical solution provides a platform for placing the speaker enclosure. Casters are installed at the bottom of the turntable to assist its rotation and ensure its stability.

[0010] Preferably, in any of the above solutions, both the first bidirectional drive assembly and the second bidirectional drive assembly include a bidirectional lead screw and a motor that drives the bidirectional lead screw to rotate.

[0011] Using the above technical solution: the first bidirectional drive assembly and the second bidirectional drive assembly respectively drive the two first movable seats and the two second movable seats to move towards each other or away from each other, so that the distance between the movable seats can be adjusted, thereby adjusting the position of the constraint plate and the glue application assembly.

[0012] Preferably, in any of the above schemes, the two first movable seats and the two second movable seats are symmetrically arranged on the first bidirectional drive assembly and the second bidirectional drive assembly, respectively.

[0013] Preferably, in any of the above solutions, the constraint plate adopts an arc-shaped structure, and a buffer pad is provided on the inner side of the constraint plate.

[0014] The above technical solution employs a constraint plate that restrains the speaker suspension from the outside, preventing displacement during adhesive application and ensuring more precise application. The constraint plate features an arc-shaped structure to fit the shape of the speaker suspension, enhancing stability. A buffer pad is placed on the inner side of the constraint plate to create a buffer between the speaker suspension and the constraint plate, preventing wear and tear on the speaker suspension.

[0015] Preferably, in any of the above solutions, the upright frame adopts an inverted U-shaped structure, and the second movable seat has an installation cavity in the middle, where the vertical drive assembly is disposed.

[0016] The above technical solution employs the following: the support frame provides an installation platform for the second bidirectional drive assembly and other structures. The second movable seat provides an installation platform for the vertical drive assembly, which drives the adhesive application assembly to move vertically so that the adhesive application assembly can be attached to the speaker surround for adhesive application.

[0017] Preferably, as described in any of the above schemes, a glue storage tank is provided on the upright frame, and a glue delivery pipe is provided between the glue storage tank and the glue application assembly.

[0018] The above technical solution involves storing adhesive in a storage tank and delivering the adhesive to the coating assembly via a delivery pipe for coating operations.

This closed-loop automatic adhesive application thickness device for speaker surrounds comprises a turntable, a first bidirectional drive assembly, a first movable seat, a constraint plate, a stand, a second bidirectional drive assembly, a second movable seat, and a vertical drive assembly.

Based on the speaker surround's dimensions, the first bidirectional drive assembly moves the first movable seat and constraint plate, causing the constraint plate to constrain the speaker surround from the outside. The second bidirectional drive assembly moves the second movable seat and adhesive application assembly, aligning the adhesive application assembly with the speaker surround. The drive motor is activated, rotating the turntable, which in turn rotates the speaker surround. The vertical drive assembly moves the adhesive application assembly downwards, applying adhesive to the speaker surround. The device can be adjusted according to the specific dimensions of the speaker surround, accommodating a wider range of sizes and offering greater flexibility.

[0020] 2. This automatic adhesive thickness closing-loop device for speaker surrounds uses a turntable as a placement platform for the speaker surrounds. Rollers are installed at the bottom of the turntable to assist its rotation and ensure stability. The constraint plate adopts an arc-shaped structure to adapt to the shape of the speaker surround, making the constraint more stable. A buffer pad is installed on the inner side of the constraint plate to create a buffer between the speaker surround and the constraint plate, preventing the constraint plate from abrading the speaker surround.
