Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia mask bonding, and specifically relates to an anesthesia mask bonding device for medical device production. Background Technique

[0002] An anesthesia mask is an indispensable tool for general anesthesia. It can cover the patient's mouth and nose, allowing the patient to inhale high-flow pure oxygen, increasing the oxygen content in the patient's lungs, thereby assisting the patient's spontaneous breathing. The anesthesia mask mainly consists of a plastic housing and a rubber ring. During the production of the anesthesia mask, it is necessary to bond the plastic housing and the rubber ring.

[0003] When bonding the plastic housing and the rubber ring, workers need to place the plastic housing on the workbench, align the glue outlet pipe with the upper edge of the plastic housing, then squeeze out the glue to the upper edge of the plastic housing, and then place the rubber ring on the plastic housing to complete the bonding of the plastic housing and the rubber ring. However, during bonding, the glue between the plastic housing and the rubber ring is likely to overflow, resulting in excess glue on the surface of the bonded anesthesia mask, affecting the aesthetics of the anesthesia mask, and it is not convenient to limit the position of the plastic housing, resulting in the rubber ring not being able to be well aligned with the plastic housing during bonding.

[0004] To this end, Chinese Patent with the publication number "CN116691010A" discloses "An Anesthesia Mask Bonding Device for Medical Device Production". Its main structure includes a mounting base plate, fixed limit rods, an electric push rod, a fixed limit frame, a mask rotation assembly, a placement rack, a plastic housing, a rubber ring body, a mask limit assembly, and a glue application assembly. Two fixed limit rods are fixedly connected to the upper side of the mounting base plate, and the two fixed limit rods are symmetrically arranged. An electric push rod is fixedly connected to the mounting base plate. A fixed limit frame is fixedly connected to the upper side of the mounting base plate. A mask rotation assembly is provided on the mounting base plate. A placement rack is provided on the mask rotation assembly. A plastic housing is placed on the placement rack. A rubber ring body is placed on the plastic housing. A mask limit assembly is provided between the two fixed limit rods and is connected to the placement rack. The glue application assembly is provided on the fixed limit frame.

[0005] When the anesthetic mask bonding device for medical device production is working, 1. The sliding ring drives the limit extrusion plate to move downward, causing the upper end of the limit extrusion plate to separate from the lower end of the sliding limit frame. The limit extrusion plate no longer restricts the sliding limit frame, and the clamping spring restores to drive the two sliding limit frames to move towards each other, so that the sliding limit frames clamp the plastic shell on the placement rack, facilitating subsequent gluing on the plastic shell; 2. The return spring restores to drive the coating frame to move towards the sliding limit frame, so that the material dropping hole on the coating frame aligns with the upper edge of the plastic shell on the placement rack. The sliding limit 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, the material dropping hole on the coating frame separates from the upper edge of the plastic shell, facilitating the coating of a quantitative amount of glue on the plastic shell, so that there will be no excess glue overflow between the plastic shell and the rubber ring body after subsequent bonding; 3. When the extrusion wedge block resets upward, it 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, pressing the rubber ring body, making the rubber ring body adhere to the plastic shell more tightly, and the bonding effect is better.

[0006] In the actual working process, since the anesthetic mask has an elliptical structure and most of the contact surfaces with the transmission components are regularly uneven curved surfaces, during its rotation, the linkage effect with the transmission components in contact with it is very poor. Therefore, the above-mentioned anesthetic mask bonding device for medical device production has a frequent occurrence of failure rate. Summary of the Invention

Before working, it is necessary to use a sealing film to seal the bottom of the sponge strip 73 so that air cannot flow upward through the sponge strip 73, and then insert the colloid suction channel 78 into the cavity of the colloid storage device, and pull the push rod upward to push the piston body 76.

Inside the colloid suction channel 78, a liquid one-way valve 710 is installed. In order to achieve the one-way flow injection of the colloid, it is necessary to make the liquid inlet direction of the liquid one-way valve 710 face downward and the exhaust direction face the colloid limiting cavity 77. The colloid limiting cavity 77 and the curved colloid flow cavity 72 are connected through a colloid flow hole 79. Inside the first longitudinal hollow housing 74 where the first longitudinal component moving cavity 75 is located, a piston body 76 capable of longitudinally moving along the first longitudinal component moving cavity 75 is placed. On the upper end surface of the piston body 76, a push rod 711 penetrating the top structure of the first longitudinal hollow housing 74 is fixedly installed.

[0029] In order to achieve the pressing and bonding function of the anesthesia mask and the rubber ring, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , it is necessary to set a pressing mechanism 8, which internally has a second longitudinal hollow housing 81 fixedly installed inside the second component fixing cavity 10, a curved convex structure 87 for sleeving the rubber ring, and a pressing rod 84 for driving the curved convex structure 87 to produce a downward pressing action.

When the anesthesia mask moves below it, apply a downward force to the first longitudinal hollow housing 74, so that the first longitudinal hollow housing 74 drives the sponge strip 73 to move downward, and the sponge strip 73 contacts the bonding surface of the anesthesia mask, so that the colloid can remain on the bonding surface of the anesthesia mask; Pull the transverse pull rod 59 outward again, so that the insertion rod 57 is inserted into the second insertion groove 511. Take a rubber ring and place the rubber ring around the periphery of the curved convex structure 87. Then, press the pressing rod 84 downward, and the pressing rod 84 will drive the rubber ring to move downward until the rubber ring is pressed against the bonding surface of the anesthesia mask.
