Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic welding equipment technology, and in particular to a multi-point simultaneous ultrasonic welding equipment with interchangeable welding head modules. Background Technology
[0002] In modern manufacturing, welding is a key joining technology. The requirements for welding processes are becoming increasingly stringent and diversified, and it is widely used in many fields, such as automobile manufacturing, electronic equipment production, aerospace, and medical devices.
[0003] With the widespread application of new materials in industry, the demand for welding different materials is increasing. For example, in the aerospace field, in addition to traditional metallic materials, composite materials, ceramic materials, and combinations of metals and non-metals are frequently encountered for welding. These materials have significantly different physical properties (such as hardness, melting point, and thermal conductivity), which also affect the requirements for welding heads. For instance, welding metallic materials may require high-energy-output welding heads, while some plastics or composite materials may require welding heads with specific frequencies and amplitudes. To effectively handle the welding of different materials, it is essential to have a mechanism for replacing multiple welding heads, allowing for rapid selection of the appropriate welding head based on the material's characteristics. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the background art by proposing a multi-point ultrasonic welding device with interchangeable welding head modules.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-point ultrasonic welding device with replaceable welding head module includes a worktable and a lifting mechanism. The lifting mechanism includes a threaded rod rotatably connected to the top of the worktable. A first motor is fixedly installed on the top of the worktable. The first motor is rotatably connected to the threaded rod through a gear transmission assembly. Three sliding rods are fixedly connected to the top of the worktable. A lifting rod is threadedly connected to the upper end of the threaded rod. Circular blocks are fixedly connected to the top of the three sliding rods. A rotating mechanism is fixedly installed on the side wall of the lifting rod.
[0007] Preferably, the gear transmission assembly includes a second gear fixedly connected to the top of the first motor, and the lower end of the threaded rod is fitted with the first gear, with the second gear meshing with the first gear.
[0008] Preferably, the rotating mechanism includes a second motor fixedly installed on the side wall of the lifting rod, a rotating rod rotatably connected through the lifting rod, the output end of the second motor being fixedly connected to one end side wall of the rotating rod, and a welding base being fixedly connected through the upper end of the rotating rod, with a replacement component provided on the welding base.
[0009] Preferably, the replacement component includes multiple rectangular grooves formed at the bottom of the welding base, with a fixing rod slidingly abutting within the multiple rectangular grooves. Two circular grooves are formed on the two side walls of the welding base, with pins slidingly abutting within the circular grooves. The pins pass through the fixing rods, and a welding mechanism is provided at the bottom of the fixing rods.
[0010] Preferably, the welding mechanism includes a horizontal plate fixedly connected to the bottom of the fixed rod, and a plurality of ultrasonic welding heads are installed at the bottom of the horizontal plate, the plurality of ultrasonic welding heads being distributed in a circular array.
[0011] Preferably, the bottom of the workbench is fixedly connected with multiple support rods.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up replaceable components, can quickly adapt to the welding requirements of different products. For example, when producing different models of mobile phones, some models may require fine welding heads to weld tiny circuit board solder joints, while others may require larger welding heads to assemble casing components. This mechanism allows the equipment to promptly change to the appropriate welding head according to the specific product, thus enabling its wide application in various complex and diverse welding tasks.
[0014] 2. This utility model, by incorporating a lifting mechanism, can precisely control the welding pressure. For example, for pressure-sensitive materials such as thin plastics or delicate electronic components, appropriate welding pressure ensures good contact between the welding head and the workpiece surface, allowing for effective transmission of ultrasonic energy and preventing damage to the workpiece due to excessive pressure or weak welds due to insufficient pressure. This precise control helps improve welding quality and reduce welding defects such as incomplete welds and burn-through.
[0015] 3. This utility model, by setting a rotating mechanism, allows all welding heads to adjust their angles simultaneously, aligning them with the welding point in the optimal position. This ensures that the ultrasonic energy is transmitted perpendicular to the welding interface or at an ideal angle, avoiding problems such as weak welding, incomplete welding, or over-welding caused by angular deviations, thereby significantly improving welding accuracy and quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 A multi-point ultrasonic welding device with replaceable welding head module includes a worktable 1 and a lifting mechanism. The lifting mechanism includes a threaded rod 3 rotatably connected to the top of the worktable 1. A first motor 4 is fixedly installed on the top of the worktable 1. The first motor 4 is rotatably connected to the threaded rod 3 through a gear transmission assembly. Three sliding rods 2 are fixedly connected to the top of the worktable 1. A lifting rod 7 is threadedly connected to the upper end of the threaded rod 3. The three sliding rods 2 are slidably connected to the lifting rod 7. There are two lifting rods 7 in total. A circular block 8 is fixedly connected to the top of the three sliding rods 2. The circular block 8 is fixedly connected to the top of the threaded rod 3. The circular block 8 is used to prevent the threaded rod 3 from falling off the sliding rod 2 and lifting rod 7. A rotating mechanism is fixedly installed on the side wall of the lifting rod 7.
[0025] The gear transmission assembly includes a second gear 6 fixedly connected to the top of the first motor 4, a first gear 5 sleeved on the lower end of the threaded rod 3, and the second gear 6 meshing with the first gear 5. The rotating mechanism includes a second motor 9 fixedly installed on the side wall of the lifting rod 7, a rotating rod 10 rotatably connected through the side wall of the lifting rod 7, the output end of the second motor 9 fixedly connected to one end of the side wall of the rotating rod 10, and a welding base 11 rotatably connected through the upper end of the rotating rod 10. A replacement assembly is provided on the welding base 11.
[0026] The replacement component includes multiple rectangular grooves 12 formed at the bottom of the welding base 11, with fixing rods 13 slidingly abutting within the multiple rectangular grooves 12. Two circular grooves 14 are formed on the two side walls of the welding base 11. The side wall of the fixing rod 13 has an opening corresponding to the circular groove 14. A pin 15 slides and abuts within the circular groove 14. The pin 15 passes through the opening of the fixing rod 13. A welding mechanism is provided at the bottom of the fixing rod 13.
[0027] The welding mechanism includes a horizontal plate 17 fixedly connected to the bottom of the fixed rod 13. Multiple ultrasonic welding heads 18 are installed at the bottom of the horizontal plate 17. The multiple ultrasonic welding heads 18 are distributed in a circular array. Multiple support rods 16 are fixedly connected to the bottom of the worktable 1.
[0028] The detailed working process of this utility model is as follows:
[0029] First, select a suitable welding head module and ensure that it is on the same plane as the workpiece. When replacing it, insert the fixing rod 13 into the rectangular groove 12, and then insert the pin 15 into the circular groove 14, passing through the fixing rod 13 to fix it. Then, when it is necessary to rotate the ultrasonic welding head 18, start the second motor 9 to drive the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the welding base 11 to rotate along the rotating rod 10, thereby driving the ultrasonic welding head 18 to rotate.
[0030] Then, the workpiece is placed on top of the workbench 1, perpendicular to the ultrasonic welding head 18. The first motor 4 is started, which drives the threaded rod 3 to rotate through the gear transmission assembly. The rotation of the threaded rod 3 causes the lifting rod 7 to move downward. The downward movement of the lifting rod 7 causes the rotating rod 10, the welding base 11, the fixed rod 13, the horizontal plate 17 and the ultrasonic welding head 18 to move downward until the ultrasonic welding head 18 comes into contact with the workpiece, and welding begins.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
