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

Abstract

The invention belongs to the technical field of ultrasonic welding machines, and discloses a welding method for ultrasonic welding machines. The welding method uses a multi-position cylinder set on the ultrasonic welding machine to drive the triple group to move along the Z direction, so as to realize the step-by-step pressing down of the welding head , to prevent that when the welding head and the welding seat move to the working position at the same time, because the welding head and the welding seat cannot strictly control the sequence of reaching the working position, it may happen that the welding head first moves to the working position while the welding seat has not yet reached the supporting position , causing the parts to be welded to be crushed, this welding method significantly improves the efficiency on the premise of ensuring the welding quality.

Description

technical field [0001] The invention relates to the technical field of ultrasonic welding machines, in particular to a welding method of an ultrasonic welding machine. Background technique [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 is rubbed with the workpiece, and the heat required for welding is generated to complete the welding of the workpiece; in the ultrasonic welding process In the process, sometimes in order to avoid the fixture or auxiliary structure, the travel 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 to the welding seat position to complete the welding operation. , due to the longer stroke of the cylinder, the action time of the cylinder is prolonged, which in turn affects the workin...
