Problems solved by technology

[0002] Ultrasonic welding machine is a device that converts electrical energy into mechanical energy. By making the welding head vibrate at high frequency, the contact head of the welding head will rub against the workpiece to generate the heat required for welding to complete the welding of the workpiece; in ultrasonic welding In the process, sometimes in order to avoid fixtures or auxiliary structures, the stroke distance between the welding head and the welding seat will be relatively large. Therefore, the cylinder on the existing ultrasonic welding machine will push the welding head down to the position of the welding seat to complete the welding operation , as the stroke of the cylinder becomes longer, the action time of the cylinder is lengthened, which affects the working efficiency of the ultrasonic welding machine; in order to shorten the time of pressing the welding head, those skilled in the art have designed a welding head and welding seat that can move at the same time However, the ultrasonic welding machine that can move the welding head and the welding seat at the same time cannot strictly control the order of the welding head and the welding seat, so the welding head may reach the welding position before the welding seat and crush Therefore, this type of machine has to use the welding seat to move to the support position under the workpiece before welding, and then the welding head moves down to the top of the workpiece for welding. Only after welding, it can move back at the same time. to the initial position

Embodiment 1

[0039] This embodiment provides an ultrasonic welding machine, such as figure 1 As shown, the ultrasonic welding machine includes a frame 1, a triple group 2, a first drive assembly, a welding seat 3 and a second drive assembly, the triple group 2 includes a welding head 21, and the triple group 2 is movably arranged on the frame 1, and The triple group 2 can move along the Z direction; the first drive assembly is connected to the triple group 2 in transmission to drive the triple group 2 to move along the Z direction, and the first drive assembly can drive the triple group 2 to move to the preset position and the first working position; The welding seat 3 is movably arranged on the frame 1, and the welding seat 3 can move along the Z direction, and the second drive assembly is connected with the welding seat 3 to drive the welding seat 3 to move along the Z direction, and the second driving assembly can drive the welding seat 3 moves to the second working position; when the f...

Embodiment 2

[0047] This embodiment provides a welding method for an ultrasonic welder, which uses the ultrasonic welder in Embodiment 1 for welding operations, such as figure 2 As shown, the welding method includes steps:

[0048] S1. Place the parts to be welded on the welding position of the ultrasonic welding machine;

[0049] S2. Make the first drive assembly drive the triple group 2 to move to a preset position, and at the same time drive the triple group 2 to move, and at the same time make the second drive assembly drive the welding seat 3 to move to the second working position, so that the workpiece to be welded is supported on the welding seat 3;

[0050] S3. Make the first drive assembly drive the triple group 2 to move to the first working position, so that the welding head 21 of the triple group 2 abuts against the workpiece to be welded;

[0051] S4, making the triple group 2 drive the welding head 21 to work, so that the welding head 21 performs welding operations on the ...

Abstract

The invention belongs to the technical field of ultrasonic welding machines, and discloses a welding method of an ultrasonic welding machine. The welding method is characterized in that a multi-position air cylinder arranged on the ultrasonic welding machine is used for driving a triple group to move along a Z direction, so that a welding head is pressed down in a grading manner, the phenomenon that when the welding head and a welding seat move towards working positions at the same time, due to the fact that the sequence of the welding head and the welding seat reaching the working positions cannot be strictly controlled, the situation that the welding head moves to the working position first but the welding seat does not reach the supporting position possibly occurs, and consequently a to-be-welded part is crushed is avoided, and the welding method obviously improves efficiency on the premise that the welding quality is guaranteed.
