Description

Technical Field

[0001] The utility model relates to the technical field of speaker basin frame production, in particular to a circle-drawing type gluing mechanism. Background Art

[0002] In the manufacturing industry, especially in the field of audio manufacturing, gluing speaker frames is a key process step. Traditional gluing methods often rely on manual operations, which is not only inefficient but also difficult to ensure the quality of gluing, especially in situations where circular gluing is required. In order to improve production efficiency and ensure the quality of gluing, automated gluing equipment has gradually been used. However, existing automated gluing equipment still has some problems with circular gluing, such as insufficient flexibility of the gluing trajectory, inability to adapt to speaker frames of different sizes, and insufficient precision in adjusting the gluing radius.

[0003] Specifically, while some automated gluing machines can apply glue in a circular motion, the center of the gluing path is usually fixed and cannot be adjusted to the size of the speaker rack. This results in the need to replace different gluing machines or molds for speaker racks of different sizes in practice, increasing production costs and complexity. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a circular gluing mechanism, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a circular gluing mechanism, including a three-axis drive module, a base, a gluing drive motor, a rotary driven module, a gluing head and a gluing constraint module. The three-axis drive module can adjust the position of the gluing head in three-dimensional space. The rotary driven module is connected to the driving end of the gluing drive motor and drives the gluing head to rotate. The gluing constraint module is used to constrain the rotation trajectory of the gluing head to reduce the radius of the gluing circle to meet specific gluing requirements.

[0006] Furthermore, the three-axis drive module includes a Y-axis drive module, an X-axis drive module and a Z-axis drive module, wherein the X-axis drive module is installed at the drive end of the Y-axis drive module, and the Z-axis drive module is installed at the drive end of the X-axis drive module.

[0007] Furthermore, the rotary driven module includes a driven seat, a first swing arm, a second swing arm, a driving seat, a screw, a handwheel, an angle adjustment seat, a glue head mounting seat, a guide seat and a linear guide rail, wherein the first swing arm is fixedly connected to the bottom end of the driven seat, the second swing arm is slidably connected to the inside of the first swing arm through the linear guide rail, the screw is threadedly connected to the driving seat and extends to the outside of the first swing arm to connect to the handwheel, the bottom end of the angle adjustment seat is rotatably connected to the glue head mounting seat, and the glue head is installed on the glue head mounting seat.

[0008] Furthermore, by rotating the handwheel to drive the screw to rotate, the second swing arm can be driven to move along the direction of the linear guide rail, thereby fine-tuning the initial position of the glue head.

[0009] Furthermore, the gluing constraint module includes an extension arm, a reserved hole, a vertical rod, a universal ball joint and a guide shaft, wherein the extension arm is installed at the lower part of the base, the reserved hole is opened at one end of the extension arm to allow the driving end of the gluing drive motor to extend and connect to the driven seat, the vertical rod is installed at the other end of the extension arm, the end of the guide shaft is connected to the bottom end of the vertical rod through a universal ball joint, and the guide seat sliding sleeve is arranged on the outside of the guide shaft.

[0010] Furthermore, the gluing constraint module constrains the rotation trajectory of the gluing head through the sliding fit of the guide shaft and the guide seat, and the flexibility of the universal ball joint, so that the center of the gluing trajectory becomes the rotating connection between the angle adjustment seat and the glue head mounting seat, thereby reducing the radius of the gluing circle.

[0011] The utility model provides a circular glue-applying mechanism. Compared with the prior art, it has the following advantages:

[0012] This circular gluing mechanism uses a three-axis drive module to precisely adjust the gluing head's position in three dimensions. Combined with a rotary follower module and a gluing constraint module, it can flexibly adjust the center and radius of the gluing trajectory to accommodate speaker racks of varying sizes. The screw and linear guide in the rotary follower module fine-tune the initial position of the gluing head to ensure gluing accuracy. Furthermore, the gluing constraint module, through the coordination of a guide shaft and universal ball joint, further constrains the gluing head's rotational trajectory, improving gluing accuracy and stability. This eliminates the need to replace different gluing equipment or molds for speaker racks of varying sizes; simply adjusting the relevant parameters of the gluing constraint module and rotary follower module allows for gluing of varying sizes, reducing production costs and complexity.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5 The present invention provides a technical solution: a circular glue-spraying mechanism, which consists of a three-axis drive module 1, a base 2, a glue-spraying drive motor 3, a rotary driven module 4, a glue-spraying head 5, and a glue-spraying constraint module 6. The three-axis drive module 1 consists of a Y-axis drive module 11, an X-axis drive module 12, and a Z-axis drive module 13 (the Y-axis drive module 11, the X-axis drive module 12, and the Z-axis drive module 13 have the same structure and all adopt the existing technology, so their specific structure and working principle are not described in detail here). The X-axis drive module 12 is arranged It is installed on the driving end of the Y-axis driving module 11, and the Z-axis driving module 13 is installed on the driving end of the X-axis driving module 12. Through the mutual cooperation of the Y-axis driving module 11, the X-axis driving module 12 and the Z-axis driving module 13, the position of the glue head 5 in the three-dimensional space can be adjusted. The base 2 is installed on the driving end of the Z-axis driving module 13, the glue driving motor 3 is installed on the upper part of the base 2, the glue constraint module 6 is installed on the lower part of the base 2, the rotary driven module 4 is installed on the driving end of the glue driving motor 3, and the glue head 5 is installed on the bottom of the rotary driven module 4;

[0021] The rotary driven module 4 is composed of a driven seat 41, a first swing arm 42, a second swing arm 43, a driving seat 44, a screw rod 45, a hand wheel 46, an angle adjustment seat 47, a glue head mounting seat 48, a guide seat 49 and a linear guide rail 410. Among them, the driven seat 41 is fixedly connected to the driving end of the glue driving motor 3, the first swing arm 42 is fixedly connected to the bottom end of the driven seat 41, the first swing arm 42 is an "L"-shaped structure component, and the second swing arm 43 is connected to the linear guide rail 410. The first swing arm 42 is slidably connected to the inside of the first swing arm 42, the driving seat 44 is mounted on one end of the second swing arm 43, and the angle adjustment seat 47 is mounted on the other end of the second swing arm 43. The screw rod 45 is threadedly connected to the driving seat 44. The end of the screw rod 45 extends to the outside of the first swing arm 42 and is connected to the hand wheel 46. The bottom end of the angle adjustment seat 47 is rotatably connected to the glue head mounting seat 48. The glue head 5 is mounted on the glue head mounting seat 48. The outside of the glue head mounting seat 48 is mounted with a guide seat 49.

[0022] When the rotary driven module 4 is working, the hand wheel 46 is rotated to drive the screw rod 45 to rotate. Under the action of the threaded connection, the second swing arm 43 can be driven to move along the direction of the linear guide rail 410, thereby driving the angle adjustment seat 47, the glue head mounting seat 48, the guide seat 49 and the glue head 5 to move as a whole, and fine-tuning the initial position of the glue head 5. When glue is needed, the glue driving motor 3 drives the rotary driven module 4 to rotate, thereby driving the glue head 5 to perform a circular motion. However, this circular motion is centered on the glue driving motor 3. Although the circular gluing purpose can be achieved in this way, the radius of the circle drawn is large and cannot meet the gluing requirements of the speaker basin frame. Therefore, it is necessary to use the glue constraint module 6 to reduce the radius of the glue circle.

[0023] The glue-applying constraint module 6 consists of an extension arm 61, a reserved hole 62, a vertical rod 63, a universal ball joint 64, and a guide shaft 65. The extension arm 61 is mounted on the lower part of the base 2. The reserved hole 62 is opened at one end of the extension arm 61. The driving end of the glue-applying drive motor 3 can extend through the reserved hole 62 and be connected and fixed to the driven seat 41. The vertical rod 63 is mounted on the other end of the extension arm 61. The end of the guide shaft 65 is connected to the bottom end of the vertical rod 63 through the universal ball joint 64. The guide seat 49 is slidably sleeved on the outside of the guide shaft 65.

[0024] As mentioned above, when there is no gluing constraint module 6, the center of the gluing trajectory is the driving end of the gluing drive motor 3. After the gluing constraint module 6 is installed, the center of the gluing trajectory becomes the rotating connection between the angle adjustment seat 47 and the glue head mounting seat 48. The specific process is that when the glue head mounting seat 48 rotates, it is constrained by the guide shaft 65, so that the guide seat 49 and the glue head mounting seat 48 as a whole slide relative to each other as the gluing circle is rotated. Combined with the universal ball joint 64, the radius of the circle can be reduced, thereby meeting the gluing needs of speaker basin racks of different sizes.
