Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic roll welding, in particular to an ultrasonic roll welding device and a welding process thereof. Background Art

[0002] Ultrasonic welding is a process in which an ultrasonic generator converts 50 / 60 Hz current into 15, 20, 30 or 40KHz electrical energy. The converted high-frequency electrical energy is converted again into mechanical motion of the same frequency through a transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude-changing rod devices that can change the amplitude. However, there are some problems with the current roll welding device: 1. When welding some soft objects, wrinkles are likely to appear at the welding point, affecting the welding quality; 2. The ultrasonic box is unstable when in use; 3. The ultrasonic box is not easy to disassemble and repair.

[0010] Preferably, one end of the second tension spring is fixedly connected to the sliding plate, and the other end of the second tension spring is fixedly connected to the base box.

[0011] Preferably, the disassembly mechanism includes a fixed seat, a slide plate, a movable rod, a limit plate, a positioning column, a limit ring, and a spring. Two symmetrically distributed fixed seats are fixedly connected to the ultrasonic box, and the fixed seat is slidably connected to the inside of the fixed seat. The movable rod is installed on the slide plate through a bearing, one end of the movable rod is fixedly connected to the limit plate, and the positioning column is fixedly connected to the limit plate. The fixed seat is in contact with the base box, and the limit plate is in contact with the base box.

A spring is arranged on the outside of the movable rod, one end of the spring is fixedly connected to the slide plate, and the other end of the spring is fixedly connected to the limit ring.

[0012] An ultrasonic roll welding process, the specific process is as follows:

[0013] Step 1: When in use, place the material on the bottom plate, and then turn the handwheel, which drives the screw to rotate. During the rotation, the screw drives the roller frame to move downward through the threaded fit between the screw and the internal threaded plate. When the hinged rod 1 and the hinged rod 2 contact the material, the hinged rod 1 pushes the rubber block to move toward the roller frame and pulls the tension spring 1. During the movement, the rubber block can be tightened by the friction between the rubber block and the material, which can avoid wrinkles at the welding position during welding and make the welding of the ultrasonic welding roller more stable.

[0014] Step 2: Then start the ultrasonic box, which welds the material through the ultrasonic welding roller. At the same time as welding, start the servo motor, which drives the driving belt to move through the driving wheel. The driving belt drives the ultrasonic box to move during the movement. The ultrasonic box can weld the material through the ultrasonic welding roller while moving. When the ultrasonic welding roller moves, the rotating roller also rotates. During the rotation of the rotating roller, multiple articulated rods 1 and 2 contact the material alternately. When the articulated rods 1 and 2 contact the material, the rubber block also contacts the material. The rubber block can be pushed by the thrust of the articulated rod 1 to drive the material to be tightened, so as to avoid wrinkles at the welding position.

[0015] Step 3: When the ultrasonic box needs to be repaired, open the box door and then pull the limit plate downward. The spring is compressed when pulling. When the positioning column is separated from the fixed seat, rotate the limit plate so that the limit plate is parallel to the slide groove on the base box. Then, the ultrasonic box can be removed for maintenance.

[0016] The beneficial effects of the present invention are as follows: the present invention relates to an ultrasonic roll welding device and a welding process thereof, which have the characteristics of eliminating wrinkles, stable movement and easy disassembly. In specific use, compared with the traditional ultrasonic roll welding device and the welding process thereof, the ultrasonic roll welding device and the welding process thereof have the following two beneficial effects:

[0017] First, by adding a wrinkle removal mechanism to the ultrasonic box, when welding the material, the rotating roller rotates so that the hinge rod 1 and the hinge rod 2 repeatedly contact the material, and the hinge rod 1 pushes the rubber block to push the material so that the welding point can be tightened, thereby avoiding wrinkles at the welding point;

[0018] Secondly, the servo motor inside the driving mechanism drives the ultrasonic box to move through the driving belt. After the driving belt is transmitted through the guide wheel, the driving belt can be in a horizontal position, thereby ensuring that the movement of the ultrasonic box is more stable. When the ultrasonic box needs to be disassembled, it is only necessary to rotate the limit plate to be parallel to the slide groove of the base box, which can make the ultrasonic box easier to disassemble.
