Description

Technical Field

[0001] This utility model is a multi-position bonding device for cold bonding of sound diaphragms, belonging to the field of sound diaphragm production technology. Background Technology

[0002] In-line mounting of the diaphragm is a common design in current speaker diaphragm structures. If the in-line mounting is precisely matched to the geometric center of the diaphragm, the diaphragm can be accurately aligned with the center of the magnetic field and the geometric position of the product, thereby enabling the speaker to achieve minimal distortion and maximum output. Traditional diaphragm assembly processes are usually done manually under a microscope, requiring a large amount of manpower and resulting in low efficiency.

[0003] Some existing multi-position bonding devices for cold bonding of sound membranes require high-speed movement during the cold bonding process. At this time, the positioning mold cavity is not limited and displacement often occurs, causing the sound membrane to shift during cold bonding and resulting in a reduction in the production quality of the sound membrane. There is an urgent need for a multi-position bonding device for cold bonding of sound membranes to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-position bonding device for cold bonding of sound diaphragms, so as to solve the problems mentioned in the background art. The present utility model has a reasonable structure and the design can limit the positioning mold cavity to prevent it from shifting, thereby preventing the positioning mold cavity from deviating during the cold bonding process of the sound diaphragm and improving the production quality of the sound diaphragm.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-position bonding device for cold bonding of sound diaphragms, including a gantry frame, a sliding groove, a servo motor, a positioning plate, a limiting plate, a limiting groove, and a positioning mold cavity.

[0006] A servo motor is installed on the left end face of the mobile platform. A threaded rod is installed on the output end of the servo motor. The threaded rod extends through and into the sliding seat. A sliding groove is opened inside the mobile platform and is slidably connected to the sliding seat. A limit plate is installed on the upper end face of the sliding seat. The limit plate extends into the positioning plate. A limit groove is opened inside the positioning plate and is fitted and connected to the limit plate. A positioning cavity is opened on the upper end face of the positioning plate.

[0007] Furthermore, the mobile platform is provided with a positioning groove inside, the specifications of which match the specifications of the positioning rod, and the two can slide together in a close fit. Both the positioning rod and the positioning groove are provided in two sets.

[0008] Furthermore, the specifications of the sliding groove match the specifications of the sliding seat, and the two can be slidably connected in a close fit.

[0009] Furthermore, the sliding seat has a threaded hole inside, the inner diameter of which is equal to the outer diameter of the threaded rod, and the two can be fitted together and rotated. There are two sets of sliding seats, and the inner diameter of the threaded hole in the two sets of sliding seats is equal and the thread direction is opposite.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a multi-position bonding device for cold bonding of sound film, including a gantry frame 1, a sliding groove 7, a servo motor 8, a positioning plate 9, a limiting plate 12, a limiting groove 14, and a positioning mold cavity 15. A control panel 13 is installed on the right end face of the gantry frame 1, a high-speed camera 10 is installed on the lower end face of the gantry frame 1, a suction device 11 is provided on the lower end face of the gantry frame 1, a workbench 2 is fixed between the gantry frames 1, a moving platform 4 is provided on the upper end face of the workbench 2, and a positioning slide rod 3 extends through the inside of the moving platform 4;

[0020] A servo motor 8 is installed on the left end of the mobile platform 4. A threaded rod 5 is installed on the output end of the servo motor 8. The threaded rod 5 extends through and into the sliding seat 6. A sliding groove 7 is opened inside the mobile platform 4 and is slidably connected to the sliding seat 6. A limit plate 12 is installed on the upper end of the sliding seat 6. The limit plate 12 extends into the positioning plate 9. A limit groove 14 is opened inside the positioning plate 9 and is fitted and connected to the limit plate 12. A positioning cavity 15 is opened on the upper end of the positioning plate 9. This design can limit the positioning cavity 15 so that it will not be displaced, prevent the positioning cavity 15 from shifting during the cold bonding process of the diaphragm, and improve the production quality of the diaphragm.

[0021] As the first embodiment of this utility model: the mobile platform 4 is provided with a positioning groove inside. The specifications of the positioning groove match the specifications of the positioning rod 3, and the two can be slidably connected. There are two sets of positioning rod 3 and positioning groove. This design makes the high-speed movement of the mobile platform 4 more stable by the slidable connection between the two sets of positioning rod 3 and positioning groove, and prevents the diaphragm from shifting during the cold bonding process, thereby improving the production quality of the diaphragm.

[0022] The specifications of the sliding groove 7 match those of the sliding seat 6, and the two can slide together in a close fit. The sliding seat 6 has a threaded hole inside, and the inner diameter of the threaded hole is equal to the outer diameter of the threaded rod 5. The two can rotate together in a close fit. There are two sets of sliding seats 6. The inner diameter of the threaded hole in the two sets of sliding seats 6 is equal and the thread direction is opposite. This design drives the threaded rod 5 to rotate through the servo motor 8, so that the threaded rod 5 can rotate together with the two sets of threaded holes with equal inner diameter and opposite thread direction, so that the two sets of sliding seats 6 can move closer or further away from each other.

[0023] The specifications of the limiting groove 14 match those of the limiting plate 12, and the two can fit together. This design drives the limiting plate 12 to move left and right through the sliding seat 6, so that the limiting plate 12 can be inserted into the limiting groove 14. The positioning plate 9 is limited and installed by the limiting plate 12, so that it will not be displaced, preventing the positioning mold cavity 15 from shifting during the cold bonding process of the sound diaphragm, and improving the production quality of the sound diaphragm.

[0024] The suction device 11, high-speed camera 10, and servo motor 8 are electrically connected to the control panel 13 via wires. This design controls the opening and closing of the suction device 11, high-speed camera 10, and servo motor 8 through the control panel 13. Multiple sets of positioning mold cavities 15 are provided. The multiple sets of positioning mold cavities 15 are of equal size and are equidistantly opened on the upper end face of the positioning plate 9. This design can perform cold bonding of the sound diaphragm in multiple positions, thereby improving the production speed of the sound diaphragm.

[0025] As a second embodiment of this utility model: the control panel 13 controls the opening and closing of the suction device 11, the high-speed camera 10, and the servo motor 8. The high-speed movement of the moving platform 4 is more stable by the sliding connection between the two sets of positioning slide rods 3 and the positioning slide groove, which prevents the sound diaphragm from shifting during the cold bonding process, thereby improving the production quality of the sound diaphragm. The servo motor 8 drives the threaded rod 5 to rotate, so that the threaded rod 5 can be connected to the two sets of threaded holes with equal inner diameter and opposite thread direction, so that the two sets of sliding seats 6 can move closer or further away from each other. The sliding seats 6 drive the limiting plate 12 to move left and right, so that the limiting plate 12 can be inserted into the limiting groove 14. The limiting plate 12 limits the installation of the positioning plate 9, so that it will not shift, preventing the positioning mold cavity 15 from shifting during the cold bonding process of the sound diaphragm, improving the production quality of the sound diaphragm, and allowing the replacement of positioning plates 9 of different specifications.
