Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and in particular to a servo turntable ultrasonic welding machine. Background Technology

[0002] Ultrasonic welding is a precision welding technology that uses high-frequency mechanical vibration energy to generate frictional heat and plastic deformation at the contact surfaces of the workpieces being welded. It achieves solid-state connection without the need for additional solder and is widely used for joining workpieces made of materials such as plastics and metals. The servo turntable ultrasonic welding machine combines the precise drive control of the servo system with the turntable multi-station structure. It achieves continuous welding operations by automatically switching stations through the turntable, making it suitable for mass production needs.

[0003] Existing servo turntable ultrasonic welding machines mostly use ordinary frame fixed components and rely on cylinders to drive ultrasonic transducers. Lacking precision guide rods, this structure makes it difficult to control welding pressure and displacement, resulting in easy fluctuations in welding force. This leads to significant differences in welding quality between different products or multiple welding of the same product, making it difficult to ensure the stability and uniformity of welding results. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a servo turntable ultrasonic welding machine, which aims to improve the problem of easy fluctuation in welding force caused by the lack of precision guide rod matching.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a servo turntable ultrasonic welding machine, comprising a base plate, a C-shaped vertical plate fixedly connected to the upper surface of the base plate, a first motor fixedly connected to the outer wall of the C-shaped vertical plate, a track rotatably mounted on the output end of the first motor, a precision lead screw mounted on the inner wall of the track, an ultrasonic transducer fixedly connected to the lower surface of the precision lead screw, a precision guide rod fixedly connected to the lower surface of the precision lead screw, an ultrasonic mold fixedly connected to the lower surface of the ultrasonic transducer, a cooling fan fixedly connected to the outer wall of the base plate, a top plate cylinder fixedly connected to the inner bottom wall of the C-shaped vertical plate, a top plate fixedly mounted on the output end of the top plate cylinder, and a switching assembly mounted on the upper surface of the base plate, the switching assembly being used to ensure accurate switching of the four workstations.

[0006] The above technical solution involves starting the first motor, which drives the precision lead screw to rotate via the track. As the lead screw rotates, it moves the ultrasonic mold downwards via the ultrasonic transducer. At this time, the ultrasonic control box sends a command to the ultrasonic transducer, causing it to emit ultrasonic waves to weld the product. This achieves precise control of welding pressure, displacement, and other parameters, ensuring that the welding force is stable and consistent for each weld. This significantly reduces welding quality differences caused by welding force fluctuations, resulting in highly uniform welding effects for different products or multiple welds of the same product, thus ensuring stable and reliable welding quality.

[0007] Preferably, the switching component includes a four-station divider, the lower surface of which is fixedly connected to the upper surface of the base plate, and the output end of which is fixedly provided with a four-station turntable.

[0008] Preferably, a clamp is fixedly connected to the upper surface of the four-station turntable, and a touch screen is fixedly connected to the upper surface of the base plate.

[0009] Preferably, a tabletop cover is fixedly connected to the upper surface of the base plate, and a button is fixedly connected to the outer wall of the tabletop cover.

[0010] Preferably, an ultrasonic box is fixedly connected inside the base plate, and a support leg is fixedly connected to the lower surface of the base plate.

[0011] Preferably, an electrical control box is fixedly connected inside the base plate, and a profile column is fixedly connected to the upper surface of the base plate.

[0012] Preferably, a synchronous belt module is fixedly connected inside the profile column, and a second motor is fixedly connected to the upper surface of the synchronous belt module.

[0013] Preferably, a drive cylinder is slidably connected to the outer wall of the synchronous belt module, and a pneumatic finger is fixedly provided at the output end of the drive cylinder.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cooperation between the C-shaped vertical plate, track, ultrasonic transducer, precision guide rod and ultrasonic mold achieves the effect of controlling welding pressure, displacement and other parameters, which helps to make the force of each welding stable and consistent, greatly reduces the difference in welding quality caused by welding force fluctuation, and makes the effect of welding different products or the same product multiple times highly uniform, thus achieving the effect of ensuring stable and reliable welding quality.

[0016] 2. In this utility model, through the cooperation between the profile column, the synchronous belt module, the second motor, the drive cylinder and the pneumatic fingers, the effect of replacing part of the manual labor with a robotic arm is achieved. This is beneficial for adapting to a variety of products and can automatically complete the actions of gripping, shifting and unloading, reducing manual intervention, improving the efficiency and accuracy of unloading, and effectively reducing labor costs.

The C-shaped upright plate 2 also supports and fixes the top plate cylinder 9. The top plate cylinder 9 pushes the top plate 10 upward by using a cylinder-pushing cam inclined surface. It has good rigidity, large force, and does not deform or shrink. The C-shaped upright plate 2 also supports and fixes the first motor 3. When the first motor 3 starts, it will rotate the precision lead screw 5 through the track 4. The C-shaped upright plate 2 also supports and fixes the precision guide rod 7. Servo motor The installation adopts a synchronous belt drive parallel precision guide rod 7, which reduces the installation height and facilitates appearance and transportation. When the precision lead screw 5 rotates, it pushes the ultrasonic mold 8 through the ultrasonic transducer 6. Welding can be carried out by starting the ultrasonic mold 8. Welding is carried out by the first motor 3 driving the precision lead screw 5 to transmit power welding, realizing precise control of welding pressure, displacement and other parameters, so that the force of each welding is stable and consistent, greatly reducing the difference in welding quality caused by welding force fluctuations, and making the effect of welding different products or multiple welding of the same product highly consistent, so as to achieve a stable and reliable welding quality.

Specifically, the base plate 1 supports and fixes the four-station divider 12. When the four-station divider 12 is in operation, it will drive the four-station turntable 13 at the output end to rotate synchronously, accurately switching between the four stations and ensuring that each station can accurately reach the designated position.

[0027] Reference Figure 1 and Figure 2 A clamp 14 is fixedly connected to the upper surface of the four-station turntable 13, a touch screen 15 is fixedly connected to the upper surface of the base plate 1, a tabletop cover 16 is fixedly connected to the upper surface of the base plate 1, a button 17 is fixedly connected to the outer wall of the tabletop cover 16, an ultrasonic electrical box 18 is fixedly connected to the inside of the base plate 1, a support leg 19 is fixedly connected to the lower surface of the base plate 1, and an electrical control box 20 is fixedly connected to the inside of the base plate 1. Specifically, the four-station turntable 13 supports and fixes the clamps 14, which are respectively located at the product picking position, ultrasonic welding position, manual feeding position, and spare position.

The base plate 1 also supports and fixes the tabletop cover 16, which in turn supports and fixes the buttons 17, which are manually activated by double buttons 17. The base plate 1 supports and fixes the ultrasonic electrical box 18, the support legs 19, and the electrical control box 20.

[0028] Reference Figure 4 A profile column 21 is fixedly connected to the upper surface of the base plate 1. A synchronous belt module 22 is fixedly connected inside the profile column 21. A second motor 23 is fixedly connected to the upper surface of the synchronous belt module 22. A drive cylinder 24 is slidably connected to the outer wall of the synchronous belt module 22. A pneumatic finger 25 is fixedly installed at the output end of the drive cylinder 24. Specifically, the base plate 1 supports and fixes the profile column 21. The aluminum profile column 21 facilitates the height adjustment of the robot arm. The profile column 21 also provides fixed support for the synchronous belt module 22, which in turn provides fixed support for the second motor 23, ensuring the stability of the second motor 23 during operation. When the drive cylinder 24 is activated, it drives the pneumatic finger 25 to clamp the material. Activating the second motor 23 causes the drive cylinder 24 to move horizontally to release the material. This allows the robot arm to replace some manual labor, adapts to various products, and can automatically complete clamping, shifting, and releasing actions, reducing manual intervention, improving the efficiency and accuracy of material unloading, and effectively reducing labor costs.

[0029] Working principle: When the device is needed, place the product into the manual feeding fixture 14, press button 17 to trigger the equipment operation program, the four-station divider 12 controls the four-station turntable 13 to rotate, rotating the fixture 14 containing the product to the lower surface of the ultrasonic mold 8, the top plate cylinder 9 is started to push the top plate 10 at the output end to press against the four-station turntable 13, the first motor 3 is started to drive the precision lead screw 5 to rotate through the track 4. When the precision lead screw 5 rotates, it drives the ultrasonic mold 8 to move downward through the ultrasonic transducer 6. At this time, the ultrasonic box 18 will send a command to the ultrasonic transducer 6, and the ultrasonic transducer 6 will start to emit ultrasonic waves to weld the product, realizing precise control of welding pressure, displacement and other parameters, so that the force of each welding is stable and consistent, greatly reducing the difference in welding quality caused by welding force fluctuation, and making the effect of welding different products or the same product multiple times highly uniform, so as to ensure the stable and reliable welding quality. After the welding is completed, the ultrasonic transducer 6 and the ultrasonic mold 8 return to their original positions, and the top plate 10 pushed by the top plate cylinder 9 also returns to its original position, which is convenient for the next welding.

[0030] After the product is welded, the four-station divider 12 controls the four-station turntable 13 to rotate again, transferring the welded product to the clamp 14 at the product picking position. The drive cylinder 24 is started to drive the pneumatic finger 25 to descend and approach the product for gripping. The second motor 23 is started to drive the drive cylinder 24 to slide on the outer wall of the synchronous belt module 22, thereby driving the pneumatic finger 25 that grips the product to move parallel to the designated placement position. This realizes the replacement of some manual labor by a robotic arm, which can adapt to a variety of products and can automatically complete the gripping, shifting and placement actions, reducing manual intervention, improving the efficiency and accuracy of material handling, and effectively reducing labor costs.

[0031] In practical use, this equipment can not only achieve precise control of welding pressure, displacement and other parameters, making the force of each welding stable and consistent, greatly reducing the difference in welding quality caused by welding force fluctuations, and ensuring a high degree of uniformity in the welding effect of different products or multiple welding of the same product, thus achieving a stable and reliable welding quality, but also realize the replacement of some manual labor with robotic arms. It can be adapted to a variety of products and can automatically complete the clamping, shifting and unloading actions, reducing manual intervention, improving the efficiency and accuracy of unloading, and effectively reducing labor costs.
