Description

Technical Field

[0001] The invention relates to the technical field of anesthesia mask bonding, in particular to an anesthesia mask bonding device for medical device production. Background Art

[0002] The anesthesia mask is an indispensable tool for general anesthesia. It can cover the patient's mouth and nose, allowing the patient to inhale a high flow of pure oxygen, increasing the oxygen content in the patient's lungs, and thus assisting the patient in breathing independently. The anesthesia mask is mainly composed of a plastic shell and a rubber ring. During the production process of the anesthesia mask, the plastic shell and the rubber ring need to be bonded.

[0003] When bonding the plastic shell and the rubber ring, a worker needs to place the plastic shell on a workbench, align the glue outlet hose with the upper edge of the plastic shell, squeeze the glue to the upper edge of the plastic shell, and then place the rubber ring on the plastic shell to complete the bonding of the plastic shell and the rubber ring. However, during bonding, the glue between the plastic shell and the rubber ring easily overflows, resulting in excess glue on the surface of the anesthesia mask after bonding, affecting the appearance of the anesthesia mask, and making it inconvenient to limit the plastic shell, resulting in the rubber ring not being well aligned with the plastic shell during bonding.

[0004] To this end, the Chinese patent with publication number "CN116691010A" publishes "An anesthesia mask bonding device for medical device production", whose main structure includes a mounting base, a fixed limit rod, an electric push rod, a fixed limit frame, a mask rotation assembly, a placement frame, a plastic shell, a rubber ring body, a mask limit assembly and a glue smearing assembly. Two fixed limit rods are fixedly connected to the side surface of the mounting base, and the two fixed limit rods are symmetrically arranged. The mounting base is fixed with an electric push rod, and the fixed limit frame is fixedly connected to the side surface of the mounting base. The mounting base is provided with a mask rotation assembly, and a placement frame is provided on the mask rotation assembly. A plastic shell is placed on the placement frame, and a rubber ring body is placed on the plastic shell. A mask limit assembly is provided between the two fixed limit rods and is connected to the placement frame, and the glue smearing assembly is provided on the fixed limit frame.

[0005] When the anesthesia mask bonding device for medical device production is working, 1. The sliding ring drives the limiting extrusion plate to move downward, so that the upper end of the limiting extrusion plate is separated from the lower end of the sliding limiting frame, and the limiting extrusion plate no longer restricts the sliding limiting frame. The clamping spring restores and drives the two sliding limiting frames to move in a direction close to each other, so that the sliding limiting frames clamp the plastic shell on the placement frame, which is convenient for subsequent glue coating on the plastic shell; 2. The return spring restores and drives the coating frame to move in a direction close to the sliding limiting frame, so that the blanking hole on the coating frame is aligned with the upper edge of the plastic shell on the placement frame, and the sliding limiting frame The positioning frame drives the plastic shell to rotate, and the glue in the coating frame is coated on the upper edge of the plastic shell. After coating is completed, the blanking hole on the coating frame is separated from the upper edge of the plastic shell, which is convenient for coating a certain amount of glue on the plastic shell, so that there will be no excess glue overflowing between the plastic shell and the rubber ring body after subsequent bonding; 3. The upward reset of the extruded wedge block will push the swing support frame and the pressing roller to swing clockwise, so that the pressing roller contacts the rubber ring body on the plastic shell, presses the rubber ring body, and makes the rubber ring body stick more tightly to the plastic shell, and the bonding effect is better.

[0006] However, in the actual working process, since the anesthesia mask has an elliptical structure and the contact surfaces with the transmission parts are mostly regular and uneven curved surfaces, the linkage effect between the anesthesia mask and the transmission parts in contact with it is very poor during the rotation process, which leads to the frequent failure rate of the anesthesia mask bonding device used in the production of the above-mentioned medical devices.
