Description

Technical Field

[0001] The utility model relates to the technical field of production and assembly of breathing valves used in masks, in particular to a diaphragm assembly mechanism of the breathing valve and automatic assembly mechanical equipment. Background Art

[0002] Masks are a kind of sanitary and anti-epidemic products, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing masks is very effective when working in dusty and other polluted environments.

[0003] Among them, in a hot and humid working environment with poor ventilation or a large workload, using a mask with a breathing valve can help the user feel more comfortable when exhaling. The breathing valve mask is a one-way valve that can discharge gas when exhaling. Because there is no resistance from the filter layer during the exhaust process, the exhaust process can be made easier. It can also take away the hot and humid gas in the mask, prevent water droplets from condensing inside the mask, and improve the user experience. Usually the breathing valve includes a bottom cover, a diaphragm and an upper cover assembled together. When exhaling, the positive pressure of the exhaust gas blows the diaphragm open to quickly expel the waste gas in the body and reduce the stuffy feeling when using the mask. The negative pressure during inhalation will automatically close the diaphragm valve to avoid inhaling pollutants from the external environment.

[0004] In the process of producing masks, before installing the breathing valve, the bottom cover, diaphragm and upper cover must be assembled to form a complete breathing valve for easy installation. However, since the diaphragm is made of silicone material, it is easy to carry static electricity, which causes adhesion between diaphragms. During the diaphragm conveying process, if the diaphragms are adhered, it is easy to assemble more than one diaphragm on the breathing valve, resulting in defective products.

[0005] In addition, traditional automatic assembly equipment can only assemble one breathing valve product at a time, resulting in low productivity and unable to meet the growing market demand. Utility Model Content

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 7 In an embodiment of the utility model, a diaphragm assembly mechanism of a breathing valve includes a diaphragm moving device 21, a diaphragm vibrating device 24, a diaphragm conveying device 40 and a diaphragm suction cup 22. One end of the diaphragm conveying device 40 is connected to the diaphragm vibrating device 24, so that the diaphragm vibrating device 24 can transfer the diaphragm in a preset direction to the diaphragm conveying device 40, and the other end thereof is provided with a diaphragm reserved position 41, and the diaphragm reserved position 41 is provided with a first sensor 42, and the first sensor 42 is used to sense whether a diaphragm is conveyed in the diaphragm reserved position 41; the diaphragm suction cup 22 is fixedly connected to the driving end of the diaphragm moving device 21, so that under the drive of the diaphragm moving device 21, the diaphragm is moved from the diaphragm reserved position 41 to the diaphragm assembly jig.

[0035] Specifically, the diaphragm assembly mechanism 20 is installed at a corresponding position of the mechanical equipment 10, preferably around the endless conveyor belt 11, and can move the diaphragm on the diaphragm reserved position 41 to the double-station fixture 12 on the endless conveyor belt 11. In order to ensure that a diaphragm suction cup 22 only sucks one diaphragm at a time, a first sensor 42 can be set below the diaphragm reserved position 41, and the first sensor 42 is preferably a photoelectric sensor in the prior art. When the first sensor 42 senses that a diaphragm is conveyed to the diaphragm reserved position 41, the diaphragm conveying device 40 can be controlled to stop running, thereby facilitating the diaphragm suction cup 22 to perform corresponding suction operations on the diaphragm.

[0036] Secondly, the diaphragm assembly mechanism 20 may be provided with a control chip in the prior art (not shown in the figure), which may receive the electrical signal sent by the first sensor 42, and then control the diaphragm conveyor belt to stop running, thereby preventing subsequent diaphragms from continuing to accumulate on the diaphragm reserved position 41. It is understandable that the control chip may also be provided on the mechanical device 10, so that the control chip may perform corresponding control operations on all components that need to be controlled on the entire mechanical device 10, and the specific control method or control steps may be performed using existing methods in the prior art.

[0037] like Figure 2 As shown, preferably, a clearance position 23 is provided on the plane where the suction hole of the diaphragm suction cup 22 is located, and the clearance position 23 is used to prevent the diaphragm suction cup 22 from mistakenly sucking up the diaphragm that has not completely entered the diaphragm reserved position 41 when performing a suction operation in the diaphragm reserved position 41.

[0038] Specifically, in order to further prevent the film suction cup 22 from sucking more than one film at a time, a corresponding avoidance position 23 can be set on the film suction cup 22. Because there is a protrusion in the middle of the film, when two films overlap, the edge of one of the films will abut against the protrusion, forming half of the two films overlapping each other. The suction hole of the film suction cup 22 is set in the middle, so after setting the avoidance position 23, it can well avoid sucking the other film.

[0039] like Figure 1 As shown, preferably, the diaphragm assembly mechanism 20 is also provided with a pressure-limiting bracket 31, a pressure-limiting cylinder 32 and a pressure-limiting block 33, the pressure-limiting bracket 31 is fixedly connected to the diaphragm assembly mechanism 20, the pressure-limiting cylinder 32 is fixedly connected to the pressure-limiting bracket 31, and the pressure-limiting block 33 is fixedly connected to the piston rod of the pressure-limiting cylinder 32. Under the drive of the pressure-limiting cylinder 32, the pressure-limiting block 33 presses and limits the diaphragm that has not yet entered the diaphragm reserved position 41 to prevent the diaphragm suction cup 22 from sucking more than one diaphragm.

[0040] Specifically, since the diaphragm is made of silicone material, it is easy to carry static electricity, which makes it easy for the diaphragms to stick together. Therefore, in order to ensure that the diaphragm suction cup 22 only absorbs one diaphragm on the diaphragm reserved position 41 at a time, a corresponding pressure-limiting block 33 is provided to press the diaphragm behind to prevent it from sticking to the diaphragm on the diaphragm reserved position 41. In addition, a pressure-limiting slide rod 34 and a linear bearing 35 can also be provided. The linear bearing 35 is fixedly connected to the pressure-limiting bracket 31, and the pressure-limiting slide rod 34 is slidably connected to the linear bearing 35. The pressure-limiting block 33 is fixedly connected to one end of the pressure-limiting slide rod 34 close to the diaphragm conveying device 40, and at the same time is also transmission-connected to the piston rod of the pressure-limiting cylinder 32, so that the vertical movement of the pressure-limiting block 33 is more stable.

[0041] like Figure 7 As shown, preferably, the utility model also provides an automatic assembly mechanical device for automatically assembling the bottom cover, diaphragm and upper cover required for the breathing valve, including the above-mentioned diaphragm assembly mechanism 20, and also including an annular conveyor belt 11, a bottom cover feeding mechanism 50, an upper cover assembly mechanism 60, a pressing mechanism 70 and a discharging mechanism 80, the annular conveyor belt 11 is provided with a synchronously moving double-station fixture 12, and the double-station fixture 12 passes through the bottom cover feeding mechanism 50, the diaphragm assembly mechanism 20, the upper cover assembly mechanism 60, the pressing mechanism 70 and the discharging mechanism 80 in sequence under the conveyance of the annular conveyor belt 11, and is in the corresponding machine The two bottom covers are simultaneously conveyed to the double-station jig 12 by the bottom cover feeding mechanism 50, the two diaphragms are simultaneously conveyed to the bottom cover of the double-station jig 12 by the diaphragm assembly mechanism 20, the two upper covers are simultaneously conveyed to the diaphragms of the double-station jig 12 by the upper cover assembly mechanism 60, the two upper covers are simultaneously conveyed to the diaphragms of the double-station jig 12 by the pressing mechanism 70, the two groups of parts on the double-station jig 12 are simultaneously pressed, thereby completing the assembly of the two breathing valves at the same time, and the discharging mechanism 80 takes out the two assembled breathing valves at the same time.

[0042] Specifically, in order to complete the automatic assembly of two groups of breathing valve parts at one time, a double-station fixture 12 can be set on the circular conveyor 11, and two groups of parts can be placed at the same time using the two placement holes on the double-station fixture 12. At the same time, other mechanisms are also provided with two corresponding moving components to move and place the two parts. In this way, the two groups of breathing valve parts can be automatically assembled at the same time, so that each station can place and assemble the corresponding two parts at the same time, thereby improving production efficiency.

[0043] like Figure 3As shown, preferably, the bottom cover feeding mechanism 50 is provided with a bottom cover moving device 55, a bottom cover vibration device 57 and a bottom cover clamp 56, the bottom cover vibration device 57 is provided with a first vibration disk 58 and a double feeding channel 59, the first vibration disk 58 transports the bottom cover to the double feeding channel 59 in a preset direction, so that the double feeding channel 59 can supply two bottom covers at the same time; the two bottom cover clamps 56 are respectively fixed to the driving ends of the bottom cover moving device 55, so as to transport the two bottom covers to the double-station fixture 12 at the same time.

[0044] Specifically, the bottom cover feeding mechanism 50 is further provided with a first slide rail 51, a first slider 52, a first stopper assembly 53 and a first cylinder 54. The first slide rail 51 is fixedly connected to the bottom cover feeding mechanism 50, the first stopper assembly 53 is fixedly connected to the first slider 52, the first slider 52 is slidably connected to the first slide rail 51, and one end of the first stopper assembly 53 is fixedly connected to the piston rod of the first cylinder 54, so that the first cylinder 54 drives the first stopper assembly 53 to move a certain distance laterally along the first slide rail 51. The first stopper assembly 53 moves under the drive of the first cylinder 54, first receives two bottom covers at the dual feed channel 59, and then moves a certain distance to form a certain misalignment with the dual feed channel 59, which can not only prevent the subsequent bottom covers of the dual feed channel 59 from continuing to be transported forward, but also move the two received bottom covers to the corresponding clamping positions of the bottom cover clamp 56. Since the thickness of the bottom cover is relatively large and it is made of plastic material, there will be no adsorption between each other. Therefore, a vibration plate can be used for material selection and two feeding channels can be used for transportation, thereby achieving the effect of loading two bottom covers at the same time.

[0045] like Figure 1 As shown, preferably, the diaphragm conveying device 40 is provided with a first diaphragm conveyor belt 43, a second diaphragm conveyor belt 44, a first motor 45 and a second motor 46, the first diaphragm conveyor belt 43 and the second diaphragm conveyor belt 44 are respectively movably connected to the diaphragm assembly mechanism 20, the first diaphragm conveyor belt 43 is transmission-connected to the first motor 45, and the second diaphragm conveyor belt 44 is transmission-connected to the second motor 46; the diaphragm vibration device 24 is provided with a second vibration disk 25 and a third vibration disk 26, the second vibration disk 25 provides a diaphragm with a preset direction to the first diaphragm conveyor belt 43, and the third vibration disk 26 provides a diaphragm with a preset direction to the second diaphragm conveyor belt 44; the two diaphragm suction cups 22 are respectively fixed to the driving end of the second material moving device, so as to simultaneously convey the two diaphragms to the double-station fixture 12.

[0046] Specifically, since the diaphragms are very thin and made of silicone material, they are easily adsorbed to each other, resulting in adhesion. Therefore, two sets of conveying devices can be respectively provided on the diaphragm conveying device 40, so as to provide diaphragms to the two reserved positions respectively, and then use two diaphragm suction cups 22 to simultaneously adsorb two diaphragms to the bottom cover of the double-station fixture 12.

[0047] like Figure 4 and Figure 7 As shown, preferably, the upper cover assembly mechanism 60 is provided with an upper cover moving device 65, an upper cover vibration device 67 and an upper cover suction nozzle 66, the upper cover vibration device 67 is provided with a fourth vibration disk 68 and a double feed channel 59, the fourth vibration disk 68 transports the upper cover to the corresponding double feed channel 59 in a preset direction, so that the double feed channel 59 can supply two upper covers at the same time; the two upper cover suction nozzles 66 are respectively fixed to the driving ends of the upper cover moving device 65, so as to transport the two upper covers to the double-station fixture 12 at the same time.

[0048] Specifically, similar to the bottom cover, the upper cover also has a certain thickness and is made of plastic material. Therefore, only one vibration plate can be used for corresponding vibration material selection, and then two upper covers are provided at the same time through the double feed channel 59. The corresponding two upper cover suction nozzles 66 can suck the two upper covers at the same time, and then move and place them on the diaphragm of the double-station fixture 12.

[0049] In addition, the upper cover assembly mechanism 60 is also provided with a second slide rail 61, a second slider 62, a second stopper assembly 63 and a second cylinder 64. The second slide rail 61 is fixedly connected to the upper cover assembly mechanism 60, the second stopper assembly 63 is fixedly connected to the second slider 62, the second slider 62 is slidably connected to the second slide rail 61, and one end of the second stopper assembly 63 is fixedly connected to the piston rod of the second cylinder 64, so that the second cylinder 64 drives the second stopper assembly 63 to move a certain distance laterally along the second slide rail 61. The second stopper assembly 63 moves under the drive of the second cylinder 64, first receives two upper covers at the double feed channel 59 of the upper cover assembly mechanism 60, and then moves a certain distance to form a certain misalignment with the double feed channel 59, which can not only prevent the subsequent upper covers of the double feed channel 59 from continuing to be transported forward, but also move the received two upper covers to the corresponding clamping positions of the upper cover suction nozzle 66.

[0050] like Figure 5 and Figure 7As shown, preferably, the pressing mechanism 70 is provided with a pressing motor 71, a pressing connecting rod 72, a third slide rail 73, a third slider 74 and a pressing block 75, the pressing motor 71 and the third slide rail 73 are fixedly connected to the pressing mechanism 70, two pressing blocks 75 are respectively fixedly connected to the third slider 74, the third slider 74 is slidably connected to the third slide rail 73, one end of the pressing connecting rod 72 is transmission connected to the driving end of the pressing motor 71, and the other end thereof is transmission connected to the third slider 74, so that the pressing motor 71 drives the third slider 74 and the pressing block 75 to move vertically along the third slide rail 73 for a certain distance, thereby simultaneously performing the pressing operation on the two groups of parts on the double-station fixture 12, and completing the assembly of the two breathing valves at the same time.

[0051] Specifically, since a corresponding snap-fit ​​structure (not shown in the figure) is provided between the bottom cover and the upper cover, the pressing mechanism 70 can be moved downward by a certain distance to press the upper cover onto the bottom cover to form a snap-fit ​​connection. In order to prevent the upper cover or the bottom cover from being crushed, a movable connection can be adopted between the pressing block 75 and the third slider 74, and a corresponding spring can be provided, so that the pressing force of the pressing block 75 on the upper cover can be adjusted by the elastic force of the spring, so that the required snap-fit ​​operation can be completed without crushing the upper cover or the bottom cover.

[0052] like Figure 6 and Figure 7 As shown, preferably, the discharging mechanism 80 is provided with a discharging and moving device 81 and a discharging suction nozzle 82, and the two discharging suction nozzles 82 are respectively fixed to the driving ends of the discharging and moving device 81, so as to perform discharging operations on the two breathing valves at the same time.

[0053] Specifically, since the breathing valve has been assembled, when discharging, it is only necessary to use the corresponding discharging suction nozzle 82 to suck the upper cover, and then put it into the discharging chute for discharging. The discharging mechanism 80 is also provided with a defective product recovery channel 83, an ejection cylinder 84 and an ejection rod 85. The ejection rod 85 is fixedly connected to the piston rod of the ejection cylinder 84, and under the drive of the ejection cylinder 84, the defective breathing valve on the double-station fixture 12 is ejected and falls into the defective product recovery channel 83. The top of the ejection rod 85 is also provided with an air port, and the air port pipeline is connected to the external high-pressure airflow, so that the ejected breathing valve is blown with high pressure, so that the breathing valve falls smoothly into the defective product recovery channel 83.

[0055] Specifically, in order to prevent the upper cover, diaphragm or bottom cover from being missed, the subsequent pressing operation will cause damage to the parts, so a corresponding sensor can be set for sensing. Preferably, a photoelectric sensor is used to sense whether the corresponding parts are placed in place. If they are not placed in place, it can be fed back to the control chip to record the number of the corresponding double-station fixture 12, and in subsequent operations, it will not be placed or pressed, but directly moved to the defective product recovery channel 83 for corresponding recycling processing.
