Description

Technical Field

[0001] This utility model relates to the field of bouncy processing technology, and in particular to a glue applicator for bouncy processing. Background Technology

[0002] In the manufacturing process of loudspeakers, the spring coil is one of the core processes. As a key component of loudspeakers, the spring coil's main function is to support the voice coil in the center of the magnetic circuit system, ensuring that the voice coil does not shift when vibrating. It also guides airflow and assists in heat dissipation, directly affecting the loudspeaker's sound quality, frequency response range, and service life.

[0003] Traditional single-point clamping means that the clamping force is applied only to a local area of ​​the speaker body. This can easily cause the body to tilt or shift due to uneven force, resulting in inaccurate alignment between the spring and the body's contact surface. This can lead to problems such as misaligned glue lines and glue leakage during glue application. Traditional clamping structures are mostly made of rigid materials, which have no cushioning ability when in contact with the speaker body. This can easily cause scratches on the outer surface of the body and even damage precision components such as the diaphragm and voice coil inside the body, increasing the defect rate. In addition, glue application requires manual handling by holding the glue gun and moving it around the speaker body or manually adjusting the position of the body to cover the annular contact surface. This not only increases the labor intensity of the operators but also easily leads to problems such as inconsistent glue line thickness due to manual operation errors, uneven movement speed, and trajectory deviation. Utility Model Content

[0004] The purpose of this invention is to solve the problems of clamping stability, easy deviation of glue application and poor flexibility in the existing technology, which lead to increased defect rate and inconsistent glue line thickness, and to provide a glue application device for wave processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glue-applying device for blasting, comprising a horn body, an elastic wheel engaged with the outer surface of the horn body, a clamping rod rotatably connected to the inner wall of the elastic wheel, a slider slidably connected to the outer surface of the clamping rod, a transmission ring rotatably connected to the outer surface of the slider, a rotating block rotatably connected to the inner wall of the transmission ring, a screw rotatably connected to the inner wall of the rotating block, a connecting block threadedly connected to the outer surface of the screw, a top plate rotatably connected to the outer surface of the connecting block, a turntable fixedly connected to the outer surface of the transmission ring, a bearing fixedly connected to the outer surface of the turntable, a base fixedly connected to the outer surface of the bearing, and a support leg fixedly connected to the outer surface of the base.

[0006] In a preferred embodiment, a spring is fixedly connected to the inner wall of the chassis, a limit bead is engaged with the inner wall of the chassis, and a limit hole is formed in the inner wall of the turntable.

[0007] In a preferred embodiment, the outer surface of the limiting bead is engaged with the inner wall of the limiting hole.

[0008] In a preferred embodiment, the outer surface of the clamping rod is rotatably connected to the inner wall of the transmission ring, and the outer surface of the transmission ring is rotatably connected to the outer surface of the top plate.

[0009] In a preferred embodiment, the outer surface of the screw is rotatably connected to the inner wall of the transmission ring.

[0010] In a preferred embodiment, the outer surface of the turntable is rotatably connected to the inner wall of the chassis.

[0011] In a preferred embodiment, the inner wall of the top plate is rotatably connected to the outer surface of the support leg.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a device that clamps the horn body to its outer surface using three elastic wheels. The clamping force is evenly applied to three points on the outer surface of the body. Compared to traditional single-point or two-point clamping methods, this effectively counteracts the problem of offset and tilting caused by uneven force on the body, ensuring that the horn body remains centered while clamped. This provides a stable and precise reference for subsequent glue application during spring processing, reducing product defects caused by positioning deviations. A turntable is fixedly connected to the bottom of the transmission ring, and the turntable is rotatably connected to the chassis via bearings. After the horn body is clamped, the operator can rotate the turntable to drive the upper clamping structure and the horn body to rotate synchronously. This design breaks the limitations of traditional fixed clamping methods, allowing the glue application tool to move flexibly around the circumference of the horn body. This easily enables glue application at different circumferential positions during spring processing, and the rotation process is smooth and without jamming. This effectively avoids glue trajectory deviation caused by manually moving the horn body, ensuring that the glue evenly covers the processing area and improving glue application quality and efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figures 1-5 As shown, this utility model provides a technical solution: a glue-applying device for blasting, including a horn body 1, an elastic wheel 8 engaged with the outer surface of the horn body 1, a clamping rod 7 rotatably connected to the inner wall of the elastic wheel 8, a slider 9 slidably connected to the outer surface of the clamping rod 7, a transmission ring 6 rotatably connected to the outer surface of the slider 9, a rotating block 5 rotatably connected to the inner wall of the transmission ring 6, a screw 4 rotatably connected to the inner wall of the rotating block 5, a connecting block 3 threadedly connected to the outer surface of the screw 4, and a top plate 2 rotatably connected to the outer surface of the connecting block 3. The outer surface of rod 7 is rotatably connected to the inner wall of transmission ring 6. The outer surface of transmission ring 6 is rotatably connected to the outer surface of top plate 2. Turntable 10 is fixedly connected to the outer surface of transmission ring 6. The outer surface of screw 4 is rotatably connected to the inner wall of transmission ring 6. Bearing 12 is fixedly connected to the outer surface of turntable 10. The outer surface of turntable 10 is rotatably connected to the inner wall of chassis 11. Chassis 11 is fixedly connected to the outer surface of bearing 12. Support leg 16 is fixedly connected to the outer surface of chassis 11. The inner wall of top plate 2 is rotatably connected to the outer surface of support leg 16.

[0021] In this embodiment, an elastic wheel 8 is designed to engage with the outer surface of the speaker body 1. The elastic wheel 8's properties ensure a secure engagement of the speaker body 1 within it. The elastic wheel 8 is rotatably connected to the inner wall of the clamping rod 7, while a slider 9 is slidably connected to the outer surface of the clamping rod 7. The slider 9 is rotatably connected to the inner wall of the transmission ring 6, and a rotating block 5 rotatably connected to one side of the inner wall rotates along with the transmission ring 6. A screw 4 is rotatably connected to the inner wall of the rotating block 5, and the screw 4 rotates under the influence of the rotating block 5. Since a connecting block 3 is threaded onto the outer surface of the screw 4, the rotation of the screw 4 causes the connecting block 3 to move along the axial direction of the screw 4, thereby rotating the transmission ring 6, causing the slider 9 to slide, and controlling the clamping rod 7. The angle is increased, causing the three clamping rods 7 to move inward and clamp the speaker body 1. The clamping force of the elastic wheels 8 on the speaker body 1 is evenly applied to three points on the outer surface of the body, effectively avoiding the body's displacement or damage caused by a single clamping point. This ensures that the speaker body 1 remains centered while clamped, providing a stable reference for subsequent glue application. The turntable 10, which is fixedly connected to the bottom of the transmission ring 6, provides support. The bottom of the turntable 10 is connected to the base 11 via a bearing 12, allowing the lower part to rotate after the upper part clamps the speaker body 1. This allows the clamped speaker body 1 to rotate and then apply glue evenly.

[0022] Example 2 like Figures 1-5 As shown, a spring 13 is fixedly connected to the inner wall of the chassis 11, a limit bead 15 is engaged with the inner wall of the chassis 11, the outer surface of the limit bead 15 is engaged with the inner wall of the limit hole 14, and the inner wall of the turntable 10 is provided with a limit hole 14.

[0023] In this embodiment, the limiting hole 14 opened on the inner wall of the turntable 10 facilitates the engagement of the limiting bead 15 with the limiting hole 14 to limit the turntable 10. The design of multiple limiting holes 14 allows the turntable 10 to rotate at multiple angles, and the elastic force of the spring 13 can limit the turntable 10, so that the clamping structure fixed on the upper part of the turntable 10 can be fixed at multiple angles.

[0024] Working principle: like Figures 1-5As shown, when the operator needs to clamp the speaker body 1, the screw 4 needs to be rotated. The outer surface of the screw 4 is threadedly connected to the connecting block 3. The rotation of the screw 4 will be converted into the linear movement of the connecting block 3 along the axial direction of the screw 4. Since the connecting block 3 and the rotating disk have an associated structure, the movement of the connecting block 3 will drive the rotating disk to rotate in the opposite direction. The inner wall of the transmission ring 6 is rotatably connected to the slider 9, and the slider 9 is slidably connected to the outer surface of the clamping rod 7. When the rotating disk rotates, it will apply a traction force to the clamping rod 7 through the slider 9, so that the opening angle of the three clamping rods 7 will decrease synchronously. The inner wall of the clamping rod 7 is rotatably connected to the elastic wheel 8. As the clamping rod 7 closes inward, the three elastic wheels 8 will synchronously approach the outer surface of the speaker body 1 and finally lock in place, and the clamping force will... The clamping force is evenly applied to three points on the outer surface of the speaker body 1, which not only avoids the body offset and tilt caused by a single clamping point, but also buffers the squeezing damage to the speaker body 1 caused by rigid clamping. The inner wall of the turntable 10 is provided with multiple limiting holes 14, and the base 11 is provided with corresponding limiting beads 15 and springs 13. When the turntable 10 rotates to the target angle, the limiting beads 15 will automatically be inserted into the corresponding limiting holes 14 under the elastic force of the springs 13. If the angle needs to be adjusted, only external force needs to be applied to rotate the turntable 10. The limiting beads 15 will be squeezed and compressed by the limiting holes 14 to compress the springs 13 and exit the hole. When it rotates to the next limiting hole 14, the limiting beads 15 will pop out and engage again, realizing multi-angle fixation and meeting the positioning requirements of different glue application positions.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
