Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to automatic assembly equipment for breathing masks. Background Art

[0002] A respirator is a common medical device that covers the user's mouth and nose and is connected to a breathing device to deliver gas to the user. It usually includes an air bag and a face cup. The common production method on the market is manual. The assembly steps include first placing the air cushion on the work platform, then applying UV glue to the adhesive surface of the face cup and sticking it to the air bag, and finally moving the assembled face cup and air bag under a light source for curing. Due to the manual assembly method, the operation is labor-intensive and slow, and the product consistency is poor, and the quality cannot be guaranteed.

[0003] Therefore, more and more breathing masks are produced by automated assembly, such as the automatic assembly machine for hollow oxygen breathing masks disclosed in China Patent CN213644728U. By completing the processes of automatic feeding, dispensing, curing and leak detection, the automatic assembly of the upper cover and the air cushion of the breathing mask is realized, which not only has high assembly efficiency, but also has guaranteed product quality. However, during the assembly process, it is necessary to glue the upper cover first, then move it to the air cushion bonding station to bond with the air cushion, and then rotate it with the air cushion to the UV curing station for glue curing. Among them, when the upper cover is glued and then driven to move, the problem of glue dripping is prone to occur, and before UV curing, the upper cover and the air cushion are prone to relative shaking during the rotation process, resulting in positional displacement and glue overflow. In addition, the existing automatic assembly equipment or the various stations on the automatic assembly line are arranged in a straight line, resulting in a large space occupied, which is not conducive to transportation and is difficult to apply to workshops with smaller spaces.

[0068] Furthermore, a limiting column 233 is provided on the connecting plate 23, and a limiting block 1A is configured corresponding to the limiting column 233 on each station. When the bottom mold 2 moves to a predetermined station, the limiting block 1A is driven to move in an operable manner so that the groove 21 on the limiting block 1A is engaged with the limiting column 233 for limiting. For example, the cross section of the groove 21 is U-shaped, and the limiting block 1A is driven to move by a cylinder. When the bottom mold 2 moves into position, the limiting block 1A is driven to move accordingly, so that the bottom mold 2 is limited, ensuring the accuracy of the bottom mold 2 position, thereby ensuring the accuracy of the glue brushing track and the curing position.

[0069] It should be mentioned that the lines or air pipes on the above-mentioned driving components are arranged to be connected to the movable parts through the tank chain, so as to ensure the simplicity of the lines and avoid the entanglement of the lines and the damage of the lines during the movement. At the same time, each driving component is arranged to be electrically connected to the control component, which can be a PLC. The circuit principle and circuit structure are prior art and will not be repeated here.
