Pressure detection assembly and ultrasonic welding equipment

Abstract

The invention discloses a pressure detection assembly and ultrasonic welding equipment. The pressure detection assembly comprises a first connecting piece, a second connecting piece, a detection unit and an elastic piece, and the first connecting piece is provided with a first guide part; the second connecting piece is connected with the first connecting piece, and the second connecting piece is provided with a second guide part matched with the first guide part; the detection unit is arranged between the first connecting piece and the second connecting piece, and the detection unit is used for collecting a pressure value between the first connecting piece and the second connecting piece; and the elastic piece is connected between the first connecting piece and the second connecting piece, and the elastic piece enables the first connecting piece and the second connecting piece to clamp the detection unit. According to the pressure detection assembly, connection gaps between a pressure detection unit and a driving part and between the pressure detection unit and a welding part can be eliminated, fluctuation is avoided, and the welding precision is effectively improved.

Description

technical field [0001] The invention relates to the technical field of detection units, in particular to pressure detection components and ultrasonic welding equipment. Background technique [0002] In the process of using ultrasonic welding equipment to weld workpieces, it is necessary to strictly control the pressure between the welding head and the workpiece. Generally, the pressure between the welding head and the workpiece is detected by the pressure detection unit to perform ultrasonic welding under a suitable pressure to ensure welding Accuracy; however, when the existing ultrasonic welding equipment is driving the welded part down, there are gaps between the pressure detection unit and the drive part, and between the pressure detection unit and the welded part, which is prone to fluctuations, resulting in deviation of the welding position. It affects the welding accuracy and welding quality. At the same time, the gap is uncontrollable and cannot be compensated for ea...

It affects welding accuracy and welding quality. At the same time, the gap is uncontrollable and cannot be compensated for each device through the setting program, which is not conducive to mass production
