[0033] like Figures 2 to 6 Shown: An ultrasonic welding positioning device for the middle section of an intelligent megaphone, comprising:

[0034] It includes a horizontally arranged base 1 and a base plate 2 vertically arranged on the base 1; that is, the base 1 and the base plate 2 are perpendicular to each other, making the device more stable and reducing the risk of accidental swing or tilt;

[0035] A support platform 3 is provided on the substrate 2, and the support platform 3 is arranged parallel to the base 1;

[0036] A positioning block 31 is provided on the top 011 of the support platform 3. The positioning block 31 passes through the hole on the top 011 of the middle product 01 and is used to position the product. The middle product 01 is initially positioned. The setting of the positioning block 31 can ensure the precise positioning of the middle product 01 during the positioning process, so that it can be accurately placed at the required position, thereby ensuring the accuracy and consistency of the production process.

[0037] The base plate 2 is also provided with telescopic components 4, and two sets of telescopic components 4 are respectively provided on both sides of the body 013, and move closer to or away from the body 013. They are used to position the left and right sides of the middle section product 01 to prevent the middle section product 01 from shaking; at the same time, by adjusting the length of the extended end of the telescopic component 4, the position of the extended end can be ensured, and personalized positioning can be performed according to the middle section product 01 of different sizes or shapes, adapting to the production requirements of products of different specifications, and increasing applicability.

[0038] By setting up the support platform 3 and the telescopic component 4, the positioning block 31 on the support platform 3 can perform preliminary positioning on the middle section product 01, and the telescopic components 4 on both sides extend out to press against the two sides of the main body 013 to prevent the middle section product 01 from shifting or tilting during the welding process, thereby improving the accuracy and stability of welding. The support platform 3 prevents the top 011 of the middle section product 01 from being suspended in the air, preventing the welding head from being deformed by the force on the top 011, reducing the risk of deformation caused by the force on the top 011 of the middle section product 01, and improving the welding quality of the middle section product 01.

[0039] When in use, the middle section product 01 is placed on the support platform 3 from the side with the top 011 facing upwards, so that the positioning block 31 passes through the hole on the top 011 of the middle section product 01, and the middle section product 01 is initially positioned. Then the protruding ends of the telescopic components 4 on both sides are extended, and the two sides of the middle section product 01 body 013 are clamped and positioned. Then the positioning piece 02 is placed at the corresponding position of the top 011 of the middle section product 01, and finally the welding head is moved down to perform ultrasonic welding on the positioning piece and the top 011. After the welding is completed, the telescopic components 4 on both sides are retracted, and the middle section product 01 is taken out, and so on to enter the next cycle.

[0040] As a preferred embodiment of the above embodiment, a step surface 32 is provided at the top 011 of the support platform 3, and the shape of the step surface 32 is adapted to the shape of the top 011 of the middle-section product 01; specifically, the step surface 32 is arranged according to the structure on the inner side of the top 011 to ensure that the welding area of ​​the top 011 of the middle-section product 01 is not suspended from the support surface, thereby providing more stable support, effectively preventing uneven welding in the welding area, and improving the consistency and quality of welding.

[0041] In this embodiment, a heating rod 5 is further provided inside the support platform 3, and a plurality of groups of heating rods 5 are arranged in parallel; on the one hand, the heating rod 5 can heat the support platform 3, and by increasing the temperature of the support platform 3, it helps to reduce the stress concentration in the welding area of ​​the middle section product 01, and reduce the stress generated during welding, thereby reducing the deformation of the product and the welding quality problems caused by the deformation; on the other hand, the use of the heating rod 5 can improve the stability of the welding process, make the welding temperature more uniform and controllable, reduce the possible impact of temperature changes during the welding process, and improve the success rate and stability of welding.

[0042] Among them, a reinforcing rib 33 is provided at the bottom 012 of the support platform 3, and the two ends of the reinforcing rib 33 are respectively perpendicular to the support platform 3 and the substrate 2; it is used to increase the overall rigidity of the support platform 3, prevent the support platform 3 from deforming or deforming during the welding process, improve the bearing capacity and stability of the support platform 3, and increase the service life of the entire device.

[0043] As a preferred embodiment of the above embodiment, the height distance from the support platform 3 to the base 1 needs to be greater than the height of the middle-section product 01; specifically, when the middle-section product 01 is placed on the support platform 3, there is a bottom distance between the bottom 012 of the middle-section product 01 and the base 1, so that the bottom 012 of the middle-section product 01 is suspended in the air, and the supporting surface of the top 011 is firmly attached to the top 011 of the middle-section product 01, so that the welding contact surface is more fitted, which helps to ensure complete contact of the welding contact surface, thereby improving the quality and reliability of welding.

[0044] In this embodiment, a plurality of avoidance positions 34 are provided at the end of the support platform 3, and the avoidance positions 34 are used to avoid the structure within the middle section product 01; ensuring that the support platform 3 will not collide or interfere with the structure within the main body 013, thereby ensuring the integrity and stability of the internal structure of the product.

[0045] As a preferred embodiment of the above embodiment, a protruding limiting surface 21 is provided on one side of the substrate 2 close to the support platform 3; specifically, the width dimension of the limiting surface 21 is greater than the width dimension of the middle product 01, and the height dimension of the limiting surface 21 is greater than the thickness dimension of the top 011. In other words, there is no need to fine-tune the side of the entire substrate 2, as long as the machining accuracy of the protruding limiting surface 21 is guaranteed, thereby reducing the machining difficulty. When in use, the product is placed downward along the limiting surface 21, and the hole of the middle product 01 is just inserted into the positioning block 31, thereby increasing the efficiency of replacing the product.

[0046] Among them, the telescopic component 4 is a telescopic rod structure, a cylinder, or an oil cylinder, one of which is selected as the product 01 ultrasonic welding positioning device according to the size of the product and the needs of the site, thereby increasing the flexibility of the device.

[0047] As a preferred embodiment of the above, the telescopic rod structure includes a bracket 41, a telescopic tube 42, a telescopic rod 43, a connecting plate 44 and a wrench 45;

[0048] One end of the telescopic rod 43 passes through the telescopic cylinder 42, and the other end is hinged to the connecting plate 44. The wrench 45 is provided with an L-shaped end 451, and the L-shaped end 451 is provided with a first hinge hole 451a and a second hinge hole 451b. The first hinge hole 451a is hinged to the bracket 41, and the second hinge hole 451b is hinged to the connecting plate 44. The wrench 45 rotates along the first hinge hole 451a to drive the telescopic rod 43 to move in the telescopic cylinder 42; when in use, the wrench 45 is bent to rotate the first hinge hole 451a on the plate. Since the second hinge hole 451b on the wrench 45 is hinged to the connecting plate 44, and the other end of the connecting plate 44 is connected to the telescopic rod 43, the wrench 45 can convert the rotational motion into the telescopic motion of the telescopic rod 43 in the telescopic cylinder 42, thereby realizing the precise adjustment and positioning of the welding joint position. The telescopic rod structure is simple, which can reduce the manufacturing cost, and reduce the cost of subsequent maintenance and replacement of parts, which helps to save overall cost.

[0049] In this embodiment, a waist-shaped hole 11 is provided on the base 1 for adjusting the position of the base 1 on the welding table; by adjusting the position of the base 1, the welding position of the middle section product 01 can be optimized, ensuring the alignment and contact between the welding area and the ultrasonic welding head, thereby improving the accuracy and quality of welding.
