Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an automatic assembly device for a one-way valve. Background Art

[0002] The airbag of the breathing mask is generally provided with an inflation tube, which is equipped with a one-way valve. When the one-way valve is pushed open by the inflation mechanism, gas can be injected into the airbag. After the inflation mechanism is removed, the gas can be stored in the airbag under the action of the one-way valve. Therefore, the connection between the one-way valve and the inflation tube is crucial. If the one-way valve and the inflation tube are improperly connected, the airbag will leak. The existing one-way valve and the inflation tube are usually connected by glue. One method is to apply glue on the one-way valve and then insert the inflation tube. This method is prone to glue dripping during the insertion of the one-way valve; the other method is to apply glue in the inflation tube and then insert the one-way valve. Although this method improves the glue dripping problem, the glue of the inflation tube is easy to gather on the gravity side (i.e., the bottom) of the inflation tube after the glue is applied, resulting in uneven glue bonding after the one-way valve is inserted, which is easy to leak. Therefore, the installation of the existing one-way valve and the inflation tube still needs further improvement. Utility Model Content

[0003] The utility model discloses an automatic one-way valve assembly device, aiming to improve the problem in the prior art that uneven glue is easily applied to the one-way valve during installation, thus causing air leakage.

[0006] As a further improvement, the bottom mold is provided with a groove for limiting the airbag body and a first limiting groove connected to the groove, and the positioning block is provided with a second limiting groove toward the first limiting groove. When the positioning block abuts against the bottom mold, the second limiting groove and the first limiting groove constitute the positioning channel.

[0007] As a further improvement, the driving structure includes a moving component and a flipping component, wherein the moving component is used to drive the rotating electric clamp to move horizontally and lift vertically, and the flipping component is used to drive the rotating electric clamp to flip between a vertical position toward the end of the feeding trough and a horizontal position toward the inflation tube.

[0008] As a further improvement, the moving assembly includes a fixed frame, a moving plate and a lifting block. The moving plate is placed horizontally between the two fixed frames and is driven to move in a horizontal direction by a first driving member configured on the fixed frame. The lifting block is adaptably connected to the fixed plate on the moving plate and is driven to lift and lower in a vertical direction by a second driving member.

[0009] As a further improvement, the flip assembly includes a flip frame arranged at the bottom of the lifting block, the flip frame is provided with a flip plate and a flip driving member for driving the flip plate to rotate, and the rotating electric clamp is fixedly connected to the flip plate.

[0010] As a further improvement, a crossbeam is installed on the fixing frame, the crossbeam is arranged parallel to the movable plate, the positioning drive member is fixedly connected to the crossbeam, and the positioning block is arranged at the bottom of the positioning drive member.

[0011] As a further improvement, the rotary electric clamp includes two symmetrically arranged clamps, the clamps are L-shaped, and a positioning groove for clamping the one-way valve is recessed along the middle of the clamps. The positioning groove is arranged in the same shape as the outer wall of the one-way valve.

[0012] As a further improvement, the end of the feed trough is provided with a discharge seat fixedly connected to the seat body, and the discharge seat is provided with a discharge hole connected to the feed trough.

[0013] As a further improvement, a plurality of workstations are arranged on the base body, each of which is equipped with two bottom molds. The positioning mechanism, clamping mechanism and feeding mechanism are installed on the one-way valve assembly station, and positioning blocks, feeding mechanisms and rotating electric clamps are arranged one by one corresponding to the two bottom molds.

[0014] As a further improvement, each bottom mold is driven by a conveying mechanism arranged on the base body to flow between the various workstations.

In addition, first apply glue to the inflatable tube, and then push the one-way valve into the inflatable tube along the axial direction of the inflatable tube through the clamping mechanism, which can evenly drive the glue to adhere to the inner wall of the inflatable tube, preventing too much glue on the gravity side and too little glue in other positions, thereby ensuring the bonding quality and avoiding airbag leakage.

[0017] 2. The bottom mold is provided with a groove for limiting the airbag body and a first limiting groove connected to the groove. The positioning block is provided with a second limiting groove toward the first limiting groove. When the positioning block abuts against the bottom mold, the second limiting groove and the first limiting groove form a positioning channel. The caliber of the positioning channel is the same as the outer diameter of the inflation tube, which supports and clamps the inflation tube, thereby preventing the inflation tube made of soft material from deforming and deviating during the assembly process.

[0018] 3. When the one-way valve is located at the discharge hole, its clamping part faces upwards, and a limiting flange is provided between the clamping part and the mounting part to limit the depth of the one-way valve inserted into the inflation tube.

[0019] 4. There are multiple stations on the base body, and each station is equipped with two bottom molds. The positioning mechanism, clamping mechanism and feeding mechanism are installed on the one-way valve assembly station, and the two bottom molds are equipped with positioning blocks, feeding mechanisms and rotating electric clamps one by one, thereby improving production efficiency. At the same time, a set of driving structures can drive the two rotating electric clamps to work, which can save structural space. The bottom molds on each station are constructed to be driven by the transmission mechanism configured on the base body to flow between the stations, thereby forming an assembly line operation and realizing automated production of products.
