Abstract

The invention provides a welding process of medical filters, and belongs to the technical field of assembling medical equipment, aiming at solving the technical problems that the prior art has an adverse effect on mechanical precision due to impact generated in ultrasonic welding and the like. The welding process comprises the steps of a. loading materials to filters: setting an assembling platform which is provided with a plurality of assembling stations, and fixing the filters on the assembling stations, wherein a welding platform is arranged on one side of the assembling platform, a plurality of supporting bases are arranged on the welding platform, and a material transferring mechanism is arranged between the assembling platform and the welding platform, and is used for grapping and transferring the filters on the assembling stations onto the supporting bases; b. welding the filters: fixing membrane groove sidewalls and filter membranes by an ultrasonic welding head through ultrasonic welding; c. unloading materials of the filters: grapping and transferring the filters on the assembling stations onto the supporting bases through the material transferring mechanism. The welding process can avoid influence of ultrasonic wave on mechanical precision of the assembling platform.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment assembly and relates to a welding process of a medical filter. Background technique [0002] The medical filter mainly filters the tiny particles in the liquid medicine to prevent the tiny particles from entering the human body. [0003] As disclosed in the patent (CN201120235730.1), a medical filter includes an upper cover and a lower cover that can form a sealed cavity after being buckled with the upper cover. The upper cover and the lower cover are provided with the above-mentioned air The cavity is divided into a liquid inlet cavity and a liquid outlet cavity with filter membranes. The liquid inlet cavity is composed of an upper cover and a filter membrane. The filter is provided with an inlet pipe communicating with the liquid inlet cavity. The liquid outlet cavity is composed of a lower cover and a filter. The filter is composed of a membrane and is provided with a liquid outlet pipe com...
