Lubricant supply mechanism, assembly equipment and lubricant supply method

Abstract

The invention relates to a lubricant supply mechanism, assembly equipment and a lubricant supply method. The lubricant supply mechanism is used for supplying a lubricant to a pressing sleeve and comprises a limiting assembly and a liquid injection assembly, wherein the limiting assembly is provided with a matching through hole for a guide pipe matching portion of the pressing sleeve to extend. The liquid injection assembly is provided with a liquid injection channel communicated with a lubricant storage chamber, and a liquid outlet port of the liquid injection channel is communicated with the matching through hole. A liquid retention part is arranged in the limiting assembly and divides the matching through hole into at least a first hole section and a second hole section which are arranged in the axial direction, and the flowing sections of the first hole section and the second hole section are different. The lubricant supply device has the beneficial effects that under the guidance of the liquid injection channel, alcohol can be uniformly and accurately supplied to a required part and cannot be adhered to a device part which does not need to be lubricated, by arranging the liquid retention part, the contact duration of the alcohol and the pressing sleeve can be prolonged, then the lubricating effect on the pressing sleeve and a guide pipe is improved, by means of the matching through hole, alcohol volatilization can be reduced, and then alcohol waste is reduced.

Description

technical field [0001] The invention relates to the technical field of medical device production, in particular to a lubricant supply mechanism, assembly equipment and a lubricant supply method. Background technique [0002] At present, most medical devices are made of plastic or rubber, which brings inconvenience to the assembly of medical devices, especially the assembly of devices with medical catheters. Taking the pressure sleeve of the medical catheter sleeve as an example, because the catheter itself has a certain flexibility, when the force is applied to it by the fixture, the catheter is easy to bend or wrinkle under the friction resistance of the pressure sleeve. The more difficult it is to assemble with the pressure sleeve, but too little force will make it difficult for the catheter to overcome the friction of the pressure sleeve, and it is not easy to complete the assembly. [0003] In this regard, a currently proposed solution is to spray lubricant on the part ...

AI Technical Summary

Problems solved by technology

[0004] However, in practical application, there are still many problems to be solved in order to implement the above countermeasures: First, due to the special use of medical devices and strict production and preparation laws, medical devices must meet the corresponding hygienic conditions and have sufficient safety, which means The use of lubricants is strictly restricted, and most lubricants will have a negative impact on human health and are not suitable for use in medical devices

However, alcohol itself is volatile, and the lubricating effect is difficult to guarantee, and excessive use will also cause safety hazards, such as causing fires
