Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0038] In one embodiment of this utility model, such as Figures 1-5As shown, a speaker grille fixing device is provided, including: a workbench 1, a mounting plate 2, and a pressure plate 3. The workbench 1; the mounting plate 2, disposed on the workbench 1, is used to place the speaker to be installed; the pressure plate 3, movably mounted on the workbench 1, has a pressing portion on its side facing the mounting plate 2 that is adapted to the shape of the grille, and the pressure plate 3 is close to or away from the mounting plate 2 to press the grille onto the speaker placed on the mounting plate 2.

[0039] The speaker grille fixing device provided by this utility model features a movable pressure plate 3 with a pressing part adapted to the shape of the grille. This allows the pressure plate 3 to precisely conform to the grille's contour and apply uniform pressure, thus achieving stable grille mounting. This structure effectively avoids the problems of uneven pressing and inaccurate positioning that easily occur in traditional manual operations, improving assembly accuracy and consistency. At the same time, the device has a simple overall structure and is easy to operate, reducing reliance on manual experience, increasing production efficiency, and reducing labor intensity.

[0040] In this embodiment, the pressure plate 3 can be symmetrically installed on both sides of the mounting plate 2, which not only allows for the installation of two at a time, but also makes the force more uniform during the pressing process, preventing the mesh cover from shifting or deforming, and improving the assembly quality and stability.

[0041] Preferably, the pressing part of the pressure plate 3 is a side groove 4, which is used to embed the appropriate mesh cover shape. The side groove 4 structure can fit tightly with the mesh cover shape, improve the positioning accuracy and contact stability during pressing, prevent the mesh cover from sliding or misaligning, and ensure assembly quality.

[0042] The speaker grille fixing device also includes a screw tightening assembly 5, which is set on the workbench 1. The screw tightening assembly 5 is used to position the speaker grille installation area and automatically tighten the fixing screws to complete the automated assembly of the grille.

[0043] Specifically, the screw tightening assembly 5 includes a motion component 501 and a screwdriver bit 502. The motion component 501 is mounted on the workbench 1, and the screwdriver bit 502 is located at the output end of the motion component 501. The motion component 501 drives the screwdriver bit 502 to position the speaker grille installation area and automatically tighten the fixing screws.

[0044] Furthermore, the motion assembly 501 includes a first drive mechanism 511 (e.g., a slide table), a second drive mechanism 512 (e.g., a cylinder), a bracket 513, and a rotary drive mechanism 514 (e.g., a motor). The first drive mechanism 511 is mounted on the worktable 1, and its output end extends horizontally. The bracket 513 is driven by the output end of the first drive mechanism 511, and moves horizontally under the drive of the first drive mechanism 511. The second drive mechanism 512 is mounted on the bracket 513, and its output end extends vertically. The rotary drive mechanism 514 is driven by the output end of the second drive mechanism 512, and moves vertically under the drive of the second drive mechanism 512. A screwdriver bit 502 is driven by the output end of the rotary drive mechanism 514, and the rotary drive mechanism 514 drives the screwdriver bit 502 to rotate around its axis.

[0045] The screw-tightening assembly 5, through the coordinated action of the first linear drive mechanism and the second linear drive mechanism, drives the screwdriver bit 502 to the preset screw hole position of the speaker and grille to be installed. The rotary drive mechanism 514 drives the screwdriver bit 502 to rotate so as to screw the screw into the preset screw hole, thereby realizing the fixed connection between the grille and the speaker to be installed.

[0046] This invention, by setting up a screw-tightening assembly 5 composed of a bidirectional drive mechanism and a rotary drive mechanism 514, enables precise positioning of the screwdriver bit 502 in the horizontal and vertical directions, and completes automatic tightening operations in conjunction with the rotational action. It not only boasts strong motion coordination but also effectively improves the automation level of the mesh cover assembly and the screw-tightening accuracy, reduces manual intervention, and enhances production efficiency and product consistency.

[0047] In other embodiments, a screw supply device can be installed, which is mounted on the sliding bracket 513 and corresponds to the screwdriver bit 502, for supplying screws to the screwdriver bit 502. This screw supply device can realize automatic screw feeding and precise docking, improving assembly efficiency and automation level.

[0048] The speaker grille fixing device also includes a drive assembly 6, which is disposed on the workbench 1. The drive assembly 6 is used to drive the mounting plate 2 to move toward the screwdriver bit 502.

[0049] Specifically, the drive assembly 6 includes a drive source 601 (e.g., a slide table), a rotation source 602 (e.g., a motor), a mounting frame 603, and a power source 604 (e.g., a cylinder). The drive source 601 is mounted on the worktable 1, and its output end extends perpendicularly along the extension direction of the first drive mechanism 511. The mounting plate 2 is mounted on the output end of the drive source 601, and moves along the direction of the screwdriver bit 502 under the drive of the drive source 601. The rotation source 602 is mounted on the mounting plate 2, and the mounting frame 603 is tractively connected to the output end of the rotation source 602. The mounting frame 603 is used to place the speaker to be installed, and the rotation source 602 drives the mounting frame 603 to rotate around its axis. The power source 604 is mounted on the mounting frame 603, and its output end extends along the direction of the speaker to be installed. The pressure plate 3 is mounted on the output end of the drive source 601, and moves along the direction of the speaker to be installed under the drive of the drive source 601.

[0050] This invention, through the setting of a drive assembly 6 containing a multi-stage drive and rotation structure, achieves multi-directional linkage adjustment of the mounting plate 2, pressure plate 3, and the speaker to be installed, improving the equipment's adaptability to different speaker specifications and its pressing flexibility. Simultaneously, this structure can work in conjunction with the screw-tightening assembly 5, enabling screw tightening operations on all sides without manual face-changing, thus automating the mesh cover assembly process and screw tightening on each side, improving production efficiency and assembly consistency.

[0051] Furthermore, the speaker grille fixing device also includes a guide component 7 connected to the mounting frame 603 and the pressure plate 3. The guide component 7 is used to guide the pressure plate 3 to move along the direction of the speaker to be installed.

[0052] Furthermore, the guide assembly 7 includes a track 701 and a slider 702. The track 701 is positioned on the side of the mounting frame 603, and the slider 702 is slidably disposed on the track 701. The pressure plate 3 is mounted on the slider 702. This guide assembly 7, through the cooperation of the track 701 and the slider 702, ensures that the pressure plate 3 moves stably along a set direction, improving the guiding accuracy and operational reliability during the pressing process, and further guaranteeing assembly quality.

[0053] The speaker grille fixing device also includes a protective cover door 8, which is installed on the workbench 1 and covers the mounting plate 2 and the pressure plate 3. The protective cover door 8 can effectively isolate the pressing operation area, prevent foreign objects from entering or parts from splashing during operation, and improve the safety of equipment operation and the cleanliness of the operating environment.

[0054] The steps for installing the grille and tightening the screws in this utility model are as follows: Place the speaker to be installed in the designated position on the mounting plate 2, and position the grille in the side groove 4. The power source 604 drives the pressure plate 3 to move towards the speaker, and the grille is pressed and fixed by the pressing part that matches the shape of the grille. The motion component 501 (first and second drive mechanisms 512) in the screw tightening assembly 5 drives the screwdriver bit 502 to move to the preset screw hole position. The rotation drive mechanism 514 drives the screwdriver bit 502 to rotate, and screws the screw into the preset hole position to complete the fixed assembly of the grille. After the operation is completed, the pressure plate 3 is reset, and the assembled speaker product is taken out.
