[0023] In actual application, the conveying mechanism 3 conveys the breathing valve to the discharge position 4. When there is a breathing valve at the discharge position 4, the material control mechanism 6 blocks the subsequent breathing valves to space the two adjacent breathing valves, so as to control the breathing valves to be supplied to the discharge position 4 one by one. The visual detection mechanism 5 visually locates the breathing valve at the discharge position 4 to detect the direction of the breathing valve, and feeds back the detection result to the angle adjustment mechanism 10. The transfer mechanism 9 drives the angle adjustment mechanism 10 to move the pick-up and placement member 11 to the discharge position 4, so that the pick-up and placement member 11 picks up the breathing valve, and the transfer mechanism 9 drives the pick-up and placement member 11 to pick up the breathing valve. The placing member 11 loads the breathing valve into the placing hole 14 of the turntable 7, and the elastic supporting member 15 supports the breathing valve. In the process of transferring the breathing valve, the angle adjustment mechanism 10 drives the picking and placing member 11 to rotate the breathing valve to the required angle according to the detection result of the visual detection mechanism 5, until the breathing valve picked up by the picking and placing member 11 is in the correct direction, and the rotating driving mechanism 8 drives the turntable 7 to rotate intermittently, so that the breathing valves on the turntable 7 are rotated one by one to the bottom of the pressing mechanism 12, and the mask fabric is above the welding head of the ultrasonic welding mechanism 13 and below the turntable 7 (ultrasonic welding mechanism 13 When the breathing valve hole of the mask fabric corresponds to the placement hole 14 carrying the breathing valve, the pressing end of the pressing mechanism 12 presses down the breathing valve in the placement hole 14. In the process of pressing down the breathing valve, the elastic support member 15 undergoes elastic deformation, causing the breathing valve to fall. After the breathing valve falls, the elastic support member 15 can recover elastically to support the subsequent breathing valve. The breathing valve is pressed down to the breathing valve hole of the mask fabric, and under the cooperation of the pressing mechanism 12 and the ultrasonic welding mechanism 13, the breathing valve is welded to the mask fabric.

The utility model has stable feeding of the breathing valve, can realize follow-up welding of the breathing valve, and improves the quality of the welding breathing valve.

[0024] In this embodiment, the transfer mechanism 9 includes a seat body 16 installed on the base 1, a swing arm 17 rotatably connected to the seat body 16, a rotating driver 18 installed on the seat body 16 and drivingly connected to one end of the swing arm 17, a translation slider 19 horizontally slidably connected to the seat body 16, and a lifting arm 20 lifting and slidingly connected to the translation slider 19, the angle adjustment mechanism 10 is installed at the bottom end of the lifting arm 20, the seat body 16 is provided with a U-shaped groove 21 with an opening facing downward, the other end of the swing arm 17 is provided with a driving guide groove 22 connected to the U-shaped groove 21, the top end of the lifting arm 20 is rotatably connected with a guide wheel 23, the guide wheel 23 penetrates the driving guide groove 22 and then extends into the U-shaped groove 21, the guide wheel 23 rolls against the inner wall of the driving guide groove 22 and the inner wall of the U-shaped groove 21, and the two ends of the U-shaped groove 21 are respectively arranged corresponding to a placement hole 14 of the turntable 7 and the discharge position 4; specifically, the rotating driver 18 and the angle adjustment mechanism 10 can both use motors.

[0025] In actual application, the rotary driver 18 drives the swing arm 17 to swing back and forth, and the inner wall of the driving guide groove 22 of the swinging swing arm 17 will contact the guide wheel 23 to move along the inner wall of the driving guide groove 22. At the same time, the guide wheel 23 moves along the track of the U-shaped groove 21, and under the translation action of the translation slider 19, the lifting arm 20 can achieve reciprocating translation and lifting actions, so that the pick-and-place member 11 can continuously complete the action of picking up the breathing valve on the material position 4 to the placement hole 14 of the turntable 7. The structural design of the transfer mechanism 9 is ingenious. Compared with the method of using a mechanical arm or a joint manipulator in the prior art, it can reduce costs and has high efficiency in transferring the breathing valve.

[0026] In this embodiment, the breathing valve feeding welding device further includes a flexible material channel 24 and a vibration plate 25, and the two ends of the flexible material channel 24 are respectively connected to the discharge port of the vibration plate 25 and the feed end of the conveying mechanism 3. In actual application, the vibration plate 25 supplies the breathing valve to the flexible material channel 24, and the breathing valve in the flexible material channel 24 moves to the conveying mechanism 3, and the conveying mechanism 3 conveys the breathing valve to the discharge position 4. Since the flexible material channel 24 can swing flexibly, when the conveying mechanism 3 moves, the flexible material channel 24 can follow and will not pull the vibration plate 25, so that stable feeding of the breathing valve can be achieved.

[0027] Specifically, the flexible channel 24 is composed of a plurality of links.

[0028] In this embodiment, the material control mechanism 6 includes a material control cylinder 26 installed at the material discharge end of the conveying mechanism 3 and a material control rod 27 installed on the piston rod of the material control cylinder 26, and the material control rod 27 can extend into the junction of the conveying mechanism 3 and the material discharge position 4. In actual application, the material control cylinder 26 drives the material control rod 27 to move back and forth, so that the material control rod 27 extends or retracts to realize material control of the breathing valve.

[0029] In this embodiment, the material discharging position 4 is equipped with a sensor 28, and the material control mechanism 6 and the transfer mechanism 9 are respectively electrically connected to the sensor 28. The sensor 28 is used to sense whether there is a breathing valve on the material discharging position 4, and to feed back a signal to the material control mechanism 6 and the transfer mechanism 9, so that the material control mechanism 6 and the transfer mechanism 9 can perform corresponding actions.

[0030] In this embodiment, the visual inspection mechanism 5 includes an annular light source 29 installed above the material discharging position 4 and a visual camera 30 mounted above the annular light source 29. An activity space for the pick-up and drop-down member 11 to enter and take materials is provided between the annular light source 29 and the visual camera 30. The visual camera 30 is an industrial camera. The visual camera 30 takes a picture of the breathing valve on the material discharging position 4, obtains an image of the breathing valve, and detects the direction of the breathing valve. The annular light source 29 emits light and irradiates the breathing valve of the material discharging position 4, so that the visual camera 30 can clearly take a picture of the breathing valve.

[0031] In this embodiment, the elastic support member 15 includes a plurality of rotating supports 31 and a plurality of elastic limiting pieces 32. The middle portion of the rotating supports 31 is rotatably connected to the inner wall of the placement hole 14. One end of the elastic limiting piece 32 is mounted on the turntable 7, and the other end of the elastic limiting piece 32 extends into the placement hole 14. One end of the rotating supports 31 extends into the placement hole 14, and the other end of the rotating supports 31 is connected to the turntable 7 via a spring 33. The plurality of rotating supports 31 and the plurality of elastic limiting pieces 32 are distributed in an annular array on the inner wall of the placement hole 14, and the plurality of rotating supports 31 are spaced apart from the plurality of elastic limiting pieces 32. When the breathing valve is placed in the placement hole 14, one end of the elastic limiting piece 32 extending into the placement hole 14 contacts the peripheral side wall of the breathing valve, the rotating supports 31 support the breathing valve, and the elastic limiting piece 32 limits the breathing valve, thereby improving the position accuracy and stability of the breathing valve in the placement hole 14. When the pressing end of the pressing mechanism 12 presses down the breathing valve in the placement hole 14, the end of the rotating bracket 31 extending into the placement hole 14 will rotate downward, and the other end of the rotating bracket 31 will stretch the spring 33 until the breathing valve falls onto the breathing valve hole of the mask fabric and the welding is completed. The pressing end of the pressing mechanism 12 is reset, and the rotating bracket 31 is reset and rotated under the action of the rebound force of the spring 33, so that the rotating bracket 31 can support the subsequent breathing valve.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
