Description

Technical Field

[0001] This invention relates to the field of mask-making technology, and in particular to a cup-shaped mask production equipment with a ring-shaped headband. Background Technology

[0002] Currently, most cup-shaped masks with headbands have two headbands welded to the main body, one above the other. Each headband's ends are welded to both sides of the main body. Existing mask machines first use a headband pulling mechanism to pull the headbands to the desired length, then a clamping mechanism holds the ends of the headbands. Next, a cutting mechanism cuts the headbands, leaving a fixed-length headband held by the clamping mechanism. The clamping mechanism then places the ends of each fixed-length headband onto welding positions on both sides of the cup-shaped mask body, and a welding mechanism welds the ends of the headbands to the mask body. This method of producing cup-shaped masks with headbands not only involves a cumbersome production process, but also results in fixed, non-adjustable headband lengths and requires a complex and costly headband cup-shaped mask machine.

[0003] Among existing patents, Chinese patent document with application number 201910817635.3 discloses a ring ear loop mask machine and a ring ear loop mask production process. The ring ear loop mask machine includes a worktable with a feeding station, a mask welding station, and a discharging station set along the mask conveying track. There are two sets of mask welding stations, located on both sides of the mask conveying track. The mask welding station has a mask welding seat and a mask welding head. The mask welding seat is located outside the mask conveying track, and the mask welding head is located directly above the mask welding seat. The mask welding station also includes a mask head pushing block, which is installed on the worktable and perpendicular to the mask conveying track. Although this ring ear loop mask machine uses the mask head pushing block to fold the mask head and wrap the ring ear loop, and then welds the mask head to the mask body, it still requires cutting the ear loop to a preset length first. The two ends of the ear loop are clamped and overlapped before welding to form a ring ear loop. Then, the two ring ear loops are fixed to the two mask heads of the mask body, making the structure of the machine complex. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a production equipment for a cup-shaped mask with a ring-shaped headband.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cup-shaped mask production equipment with a ring headband includes a machine base, a linear ring-shaped circulating conveyor mechanism mounted on the machine base, a circulating conveyor surface mounted on the linear ring-shaped circulating conveyor mechanism for carrying the cup-shaped mask body, and nose wire feeding device, nose wire welding mechanism, upper ring headband device, ear flap welding device, valve hole edge welding mechanism, punching mechanism, breathing valve welding device, and unloading device arranged sequentially on the machine base along the conveying direction of the linear ring-shaped circulating conveyor mechanism. The upper ring headband device includes a ring headband feeding mechanism mounted on the machine base and located on one side of the linear ring-shaped circulating conveyor mechanism, and a ring headband feeding mechanism mounted on the machine base and supported by the linear ring-shaped circulating conveyor mechanism. The upper annular headband feeding mechanism and the conveying carrier include a carrier plate, a carrier cavity recessed on the top surface of the carrier plate, two flap holes at both ends of the carrier cavity, and four positioning posts respectively set on the carrier plate and located on the outside of the carrier cavity. Two positioning posts are located on both sides of one flap hole, and the other two positioning posts are located on both sides of the other flap hole. The annular headband feeding mechanism picks up the annular headband supplied by the annular headband mechanism and puts the annular headband over the four positioning posts. The two sections of the annular headband are respectively located on the two side ears of the cup-shaped mask body carried by the conveying carrier. The flap welding device is used to flip the two side ears of the cup-shaped mask body upward and weld them to the side wall of the cup-shaped mask body respectively.

[0007] Furthermore, the transport carrier also includes a fixing mechanism disposed on the carrier plate, which is used to fix the cup-shaped mask body inside the carrier cavity.

[0008] Furthermore, the fixing mechanism includes at least two rotating clamping members rotatably connected to the carrier plate and at least two rotating drivers disposed on the carrier plate. One rotating driver is driven to be connected to one rotating clamping member. The rotating driver is used to drive the rotating clamping member to press and fix the edge of the cup-shaped mask body onto the carrier cavity.

[0009] Furthermore, the number of rotating clamping components is four, the rotating driver is a torsion spring, and two rotating grooves are provided at both ends of the carrier plate. The flap hole is located between the two rotating grooves. The middle part of the rotating clamping component is rotatably connected to the two side walls of the rotating groove. The bottom end of the rotating clamping component is elastically connected to the carrier plate via the torsion spring. The elastic force of the torsion spring is transmitted to the top of the rotating clamping component to press and fix the edge of the cup-shaped mask body onto the carrier cavity. The cup-shaped mask production equipment with annular headband also includes a feeding top opening mechanism and a discharging top opening mechanism installed on the machine base and located at the feeding end and discharging end of the linear annular circulating conveyor mechanism, respectively. The discharging top opening mechanism is arranged opposite to the discharging device. The feeding top opening mechanism or the discharging top opening mechanism is used to push the bottom end of the rotating clamping component upward so that the top of the rotating clamping component releases the pressing and fixing of the cup-shaped mask body.

[0010] Furthermore, the ring head belt feeding mechanism includes a circulating feeding and conveying module located on one side of the linear ring circulating conveying mechanism and multiple feeding carriers installed on the conveying surface of the circulating feeding and conveying module. The circulating feeding and conveying module is used to drive the multiple feeding carriers to move cyclically. The feeding carriers include a feeding plate installed on the conveying surface of the circulating feeding and conveying module and two hanging plates set at both ends of the feeding plate. The two hanging plates are used to fix the ring head belt.

[0011] Furthermore, the annular headband feeding mechanism includes a support frame mounted on the machine base, a movable plate movably mounted on the support frame, a translation drive mechanism mounted on the support frame and used to drive the movable plate to move horizontally, a spacing adjustment mechanism mounted on the movable plate, and two sets of pick-and-place robots drivenly connected to the spacing adjustment mechanism. The spacing adjustment mechanism is used to adjust the spacing between the two sets of pick-and-place robots, and the translation drive mechanism is used to drive the two sets of pick-and-place robots to reciprocate above the annular headband mechanism and the linear annular circulating conveyor mechanism. The pick-and-place robot includes a lifting drive mechanism mounted on the spacing adjustment mechanism, a lifting plate mounted on the lifting end of the lifting drive mechanism, and two gripper modules spaced apart on the lifting plate.

[0012] Furthermore, the ear-flipping welding device includes a frame, an upward-pushing ear-flipping mechanism, and two welding mechanisms. The frame is mounted on the machine base, and the two welding mechanisms are symmetrically and obliquely mounted on the frame. The upward-pushing ear-flipping mechanism is located below the upper conveying surface of the linear annular circulating conveying mechanism. The upward-pushing ear-flipping mechanism includes an upward-pushing drive module, an upward-pushing plate mounted on the upward-pushing end of the upward-pushing drive module, two welding bottom molds mounted on the upward-pushing plate, and two ear-flipping plates mounted on the upward-pushing plate. The two welding bottom molds are located between the two ear-flipping plates. The two welding mechanisms, the two welding bottom molds, and the two ear-flipping plates are respectively arranged in a one-to-one correspondence. A welding slope is provided on the side of the welding bottom mold near the ear-flipping plate. A welding through hole is opened at the top of the ear-flipping plate, which corresponds to the welding slope. The welding end of the welding mechanism can pass through the welding through hole. A through hole is opened in the middle of the carrier cavity. Two ear-flipping holes are located at both ends of the through hole. The ear-flipping holes communicate with the through hole. The welding bottom molds and ear-flipping plates can pass through the through hole.

[0013] Furthermore, the ear-flipping welding device also includes a pressing and abutting mechanism installed on the frame and located between the two welding mechanisms. The pressing and abutting mechanism includes a vertical rod installed on the frame, a pressing driver installed on the vertical rod, and a pressing member installed on the pressing drive end of the pressing driver. Two inclined pressure plates are symmetrically and obliquely arranged on both sides of the pressing member. The inclined pressure plates have clearance grooves for the welding end of the welding mechanism to pass through. The clearance grooves are corresponding to the welding through holes.

[0014] Furthermore, the welding mechanism includes a mounting base inclinedly mounted on the frame, a slide block slidably connected to the mounting base, an ultrasonic welding head mounted on the slide block, a motion driver mounted on the mounting base for driving the slide block closer to or away from the conveyor, a slider slidably connected to the bottom surface of the slide block, an inclined plate mounted on the slider and located below the ultrasonic welding head, and a tension spring elastically connected to the slider and the slide block. The inclined plate can penetrate the welding through hole and abut against the welding inclined surface. Initially, the pressure surface of the inclined plate extends beyond the welding surface of the ultrasonic welding head.

[0015] Furthermore, the cup-shaped mask production equipment with a ring headband also includes a pad printing device installed on the machine base and located on one side of the linear ring conveyor mechanism. The pad printing device is located between the nose wire welding mechanism and the upper ring headband device.

[0016] The beneficial effects of this invention are as follows: In practical applications, the cup-shaped mask body is placed in the cavity of a conveying carrier. The nose wire device supplies a fixed length of nose wire to the nose wire welding mechanism, and the annular headband mechanism supplies annular headbands to the annular headband feeding mechanism. A linear annular circulating conveying mechanism circulates multiple conveying carriers, causing the conveying carrier carrying the cup-shaped mask body to move sequentially to the nose wire welding mechanism, the upper annular headband device, the ear-flipping welding device, the valve hole edge melting mechanism, the punching mechanism, the breathing valve welding device, and the unloading device. The nose wire welding mechanism welds the nose wire to the side wall of the cup-shaped mask body. The annular headband feeding mechanism of the upper annular headband device first picks up the annular headband supplied by the annular headband mechanism, then stretches the annular headband into a rectangle and fits it around the four positioning posts of the conveying carrier. The two segments of the ring headband are located above the two side ears of the cup-shaped mask body with the nose wire welded on. The two flap welding ends of the flap welding device first pass through the two flap holes and fold the two side ears of the cup-shaped mask body upward. Then, the two welding ends of the flap welding device weld the two folded side ears to the side wall of the cup-shaped mask body to partially wrap the two segments of the ring headband and fix the ring headband to the two side ears of the cup-shaped mask body. The valve hole welding mechanism welds the valve hole edge of the cup-shaped mask body with the ring headband fixed on it. The punching mechanism punches the cup-shaped mask body after the valve hole edge is welded. The breathing valve welding device welds the breathing valve into the valve hole of the cup-shaped mask body. The unloading device unloads the cup-shaped mask with the ring headband and breathing valve from the conveyor carrier. This invention automatically fixes a complete loop headband to the two ear loops of the cup-shaped mask body. There is no need to cut the headband during the production process. It can produce a cup-shaped mask with a complete loop headband as two headbands. Since the two ear loops of the cup-shaped mask body partially wrap the loop headband, the length of the two headbands of the cup-shaped mask can be adjusted by adjusting the relative position of the loop headband and the cup-shaped mask body. This makes the relative length of the two headbands of the produced cup-shaped mask adjustable. Attached Figure Description

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0033] like Figures 1 to 13As shown, the present invention provides a cup-shaped mask production equipment with a ring headband, which includes a machine base 1, a linear ring-shaped circulating conveyor mechanism 2 mounted on the machine base 1, multiple conveying carriers 3 mounted on the circulating conveyor surface of the linear ring-shaped circulating conveyor mechanism 2 for carrying the cup-shaped mask body, and nose wire supply device 4, nose wire welding mechanism 5, upper ring headband device 6, ear flap welding device 7, valve hole edge welding mechanism 8, punching mechanism 9, breathing valve welding device 10, and unloading device 11 arranged sequentially on the machine base 1 along the conveying direction of the linear ring-shaped circulating conveyor mechanism 2. The upper ring headband device 6 includes a ring headband supply mechanism 12 mounted on the machine base 1 and located on one side of the linear ring-shaped circulating conveyor mechanism 2, and a ring headband mounted on the machine base 1 and mounted above the linear ring-shaped circulating conveyor mechanism 2. The conveyor 3 includes a loading mechanism 13 and a conveying carrier 3, which includes a carrier plate 14, a cavity 15 recessed on the top surface of the carrier plate 14, two flap holes 16 at both ends of the cavity 15, and four positioning posts 17 respectively disposed on the carrier plate 14 and located on the outside of the cavity 15. Two positioning posts 17 are located on both sides of one flap hole 16, and the other two positioning posts 17 are located on both sides of the other flap hole 16. The annular headband loading mechanism 13 picks up the annular headband 98 supplied by the annular headband mechanism 12 and fits the annular headband 98 around the four positioning posts 17. The two segments of the annular headband 98 are respectively located on the two side ears of the cup-shaped mask body carried by the conveyor 3. The flap welding device 7 is used to fold the two side ears of the cup-shaped mask body upward and weld them to the side wall of the cup-shaped mask body in a folded manner.

[0034] In practical applications, the cup-shaped mask body is placed in the cavity 15 of the conveying carrier 3. The nose wire device 4 supplies a fixed length of nose wire to the nose wire welding mechanism 5, and the ring headband mechanism 12 supplies the ring headband 98 to the ring headband feeding mechanism 13. The linear ring circulation conveying mechanism 2 circulates multiple conveying carriers 3, so that the conveying carrier 3 carrying the cup-shaped mask body moves sequentially to the nose wire welding mechanism 5, the upper ring headband device 6, the ear-flipping welding device 7, the valve hole edge melting mechanism 8, the punching mechanism 9, the breathing valve welding device 10, and the unloading device 11. The nose wire welding mechanism 5 welds the nose wire to the side wall of the cup-shaped mask body. The ring headband feeding mechanism 13 of the upper ring headband device 6 first picks up the ring headband 98 supplied by the ring headband mechanism 12, and then stretches the ring headband 98 into a rectangle and fits it onto the four positioning posts of the conveying carrier 3. 17. In addition, the two segments of the ring headband 98 are located above the two side ears of the cup-shaped mask body with the nose wire welded on. The two flapping ends of the flapping welding device 7 first pass through the two flapping holes 16 and fold the two side ears of the cup-shaped mask body upward. Then, the two welding ends of the flapping welding device 7 weld the two side ears after folding upward to the side wall of the cup-shaped mask body to partially wrap the two segments of the ring headband 98 to fix the ring headband 98 to the two side ears of the cup-shaped mask body. The valve hole welding mechanism 8 performs valve hole welding on the cup-shaped mask body with the ring headband 98 fixed on it. The punching mechanism 9 punches the cup-shaped mask body after the valve hole welding. The breathing valve welding device 10 welds the breathing valve into the valve hole of the cup-shaped mask body. The unloading device 11 unloads the cup-shaped mask with the ring headband 98 and the breathing valve from the conveyor carrier 3. The machine structure of this invention is simple and automatically fixes a complete ring headband 98 to the two ear loops of the cup-shaped mask body. There is no need to cut the headband during the production process. It can produce a cup-shaped mask with a complete ring headband 98 as two headbands. Since the two ear loops of the cup-shaped mask body partially wrap the section of the ring headband 98, the length of the two headbands of the cup-shaped mask can be adjusted by adjusting the relative position of the ring headband 98 and the cup-shaped mask body. This makes the relative length of the two headbands of the produced cup-shaped mask adjustable.

[0035] In this embodiment, the conveying carrier 3 further includes a fixing mechanism 18 disposed on the carrier plate 14. The fixing mechanism 18 is used to fix the cup-shaped mask body in the carrier cavity 15. In practical applications, after the cup-shaped mask body is placed on the carrier cavity 15 of the conveying carrier 3, the carrier cavity 15 positions the cup-shaped mask body, and the fixing mechanism 18 fixes the cup-shaped mask body on the carrier cavity 15 to ensure the positional accuracy and stability of the cup-shaped mask body on the conveying carrier 3.

[0036] In this embodiment, the fixing mechanism 18 includes at least two rotating clamping members 19 rotatably connected to the carrier plate 14 and at least two rotating drivers 20 disposed on the carrier plate 14. One rotating driver 20 is drivenly connected to one rotating clamping member 19. The rotating driver 20 is used to drive the rotating clamping member 19 to press and fix the edge of the cup-shaped mask body onto the carrier cavity 15. In practical applications, when it is necessary to place the cup-shaped mask body onto the carrier cavity 15 or remove the cup-shaped mask from the carrier cavity 15, the rotating driver 20 actively or passively drives the rotating clamping member 19 to rotate, so that the rotating clamping member 19 opens relative to the carrier plate 14, at which time the cup-shaped mask can be placed or removed; when the carrier cavity 15 carries a cup-shaped mask, the rotating driver 20 drives the rotating clamping member 19 to rotate in the opposite direction, so that the rotating clamping member 19 closes relative to the carrier plate 14, thereby pressing the edge of the cup-shaped mask body onto the carrier cavity 15.

[0037] In this embodiment, there are four rotating clamping members 19, the rotating driver 20 is a torsion spring, and two rotating grooves 21 are provided at both ends of the carrier plate 14. The flap hole 16 is located between the two rotating grooves 21. The middle part of the rotating clamping member 19 is rotatably connected to the two side walls of the rotating groove 21. The bottom end of the rotating clamping member 19 is elastically connected to the carrier plate 14 via the torsion spring. The elastic force of the torsion spring is transmitted to the top of the rotating clamping member 19 to press and fix the edge of the cup-shaped mask body onto the carrier cavity 15. The cup-shaped mask production equipment with an annular headband also includes a feeding top opening mechanism 22 and a discharging top opening mechanism 23 installed on the machine base 1 and located at the feeding end and discharging end of the linear annular circulating conveying mechanism 2, respectively. The discharging top opening mechanism 23 is arranged opposite to the discharging device 11. The feeding top opening mechanism 22 or the discharging top opening mechanism 23 is used to push the bottom end of the rotating clamping member 19 upward so that the top end of the rotating clamping member 19 releases the pressing and fixing of the cup-shaped mask body.

[0038] Initially, the spring force of the torsion spring drives the rotating clamping member 19 to close relative to the carrier plate 14. When the conveying carrier 3 moves to the loading top opening mechanism 22 or the unloading top opening mechanism 23, the loading top opening mechanism 22 or the unloading top opening mechanism 23 applies an upward force to the bottom end of the rotating clamping member 19, causing the rotating clamping member 19 to open and rotate relative to the carrier plate 14. The torsion spring is in a compressed state, so the cup-shaped mask body can be placed on the carrier cavity 15 of the conveying carrier 3 or the cup-shaped mask can be removed from the carrier cavity 15 of the conveying carrier 3. When the loading top opening mechanism 22 or the unloading top opening mechanism 23 releases the upward force on the bottom end of the rotating clamping member 19, the torsion spring elastically recovers. The rebound force of the torsion spring drives the rotating clamping member 19 to close and rotate relative to the carrier plate 14, so that the rotating clamping member 19 presses and fixes the cup-shaped mask body on the carrier cavity 15. The positional layout of the four rotating clamping members 19 ensures stable compression of the cup-shaped mask without affecting the flapping and welding of the two side ears of the cup-shaped mask body by the flapping and welding device 7.

[0039] Specifically, the rotating clamping member 19 includes an L-shaped plate 24 and a driving arc plate 25 integrally connected to one end of the L-shaped plate 24. The driving arc plate 25 is positioned opposite to the L-shaped plate 24, and the connection between the L-shaped plate 24 and the driving arc plate 25 is rotatably connected to the inner wall of the rotating groove 21. One end of the torsion spring is connected to the driving arc plate 25, and the end of the L-shaped plate 24 away from the driving arc plate 25 is used to press the cup-shaped mask body into the carrier cavity 15. In practical applications, when it is necessary to drive the rotating clamping member 19 to open and rotate relative to the carrier plate 14, the feeding top opening mechanism 22 or the unloading top opening mechanism 23 applies an upward force to the driving arc plate 25, so that the rotating clamping member 19 can open and rotate relative to the carrier plate 14 and compress the torsion spring. This structural design not only facilitates the rotation of the rotating clamping member 19 relative to the carrier plate 14, but also facilitates the feeding top opening mechanism 22 or the unloading top opening mechanism 23 to control the opening of the rotating clamping member 19 relative to the carrier plate 14.

[0040] Specifically, the loading top opening mechanism 22 and / or the unloading top opening mechanism 23 includes a top driver 26 mounted on the machine base 1, a top plate 27 mounted on the top end of the top driver 26, and four top blocks 28 disposed on the top plate 27. The four top blocks 28 are respectively disposed one-to-one with the bottom ends of the four rotating clamping parts 19. Preferably, the top driver 26 can be a vertically upward cylinder, and the structure of the loading top opening mechanism 22 is the same as that of the unloading top opening mechanism 23. In practical applications, the top driver 26 drives the top plate 27 and the four top blocks 28 to move upward. The moving top blocks 28 apply an upward force to the driving arc plate 25 of the rotating clamping parts 19, so that the four rotating clamping parts 19 can open and rotate relative to the carrier plate 14.

[0041] In this embodiment, the annular headband feeding mechanism 12 includes a circulating feeding and conveying module 29 located on one side of the linear annular circulating conveying mechanism 2 and multiple feeding carriers 30 mounted on the conveying surface of the circulating feeding and conveying module 29. The circulating feeding and conveying module 29 is used to drive the multiple feeding carriers 30 to move cyclically. The feeding carriers 30 include a feeding plate 31 mounted on the conveying surface of the circulating feeding and conveying module 29 and two hanging plates 32 disposed at both ends of the feeding plate 31. The two hanging plates 32 are used to fix the annular headband 98. In practical applications, the annular headband 98 is fitted over the two hanging plates 32. The circulating feeding and conveying module 29 drives the multiple feeding carriers 30 to move cyclically. The cyclically moving feeding carriers 30 convey the annular headband 98 to the loading position. The annular headband loading mechanism 13 picks up the annular headband 98 at the loading position and fits the annular headband 98 over the four positioning posts 17.

[0042] Specifically, a detection groove 33 is recessed on the top surface of the middle part of the hanging plate 32. A detector is installed at the output end of the circulating material feeding and conveying module 29. The detector is a fiber optic sensor and is used to detect the annular headband 98 at the detection groove 33. The detector is electrically connected to the circulating material feeding and conveying module 29 and the annular headband feeding mechanism 13. In practical applications, when the detector detects an annular headband 98 on the feeding carrier 30, the detector sends feedback signals to the circulating material feeding and conveying module 29 and the annular headband feeding mechanism 13, causing the circulating material feeding and conveying module 29 to stop conveying the feeding carrier 30, and the annular headband feeding mechanism 13 to pick up the annular headband 98 on the feeding carrier 30. After the annular headband feeding mechanism 13 picks up the annular headband 98, the detector can no longer detect the annular headband 98. The circulating material feeding and conveying module 29 drives multiple feeding carriers 30 to move until the detector detects the annular headband 98 on the next feeding carrier 30.

[0043] In this embodiment, the annular headband feeding mechanism 13 includes a support frame 34 mounted on the machine base 1, a movable plate 35 movably mounted on the support frame 34, a translation drive mechanism 36 mounted on the support frame 34 and used to drive the movable plate 35 to translate, a spacing adjustment mechanism 37 mounted on the movable plate 35, and two sets of pick-and-place robots 38 drivenly connected to the spacing adjustment mechanism 37. The spacing adjustment mechanism 37 is used to adjust the spacing between the two sets of pick-and-place robots 38, and the translation drive mechanism 36 is used to drive the two sets of pick-and-place robots 38 to feed the annular headband. The headband mechanism 12 reciprocates above the linear annular circulating conveyor 2; the pick-and-place robot 38 includes a lifting drive mechanism 39 mounted on the spacing adjustment mechanism 37, a lifting plate 40 mounted on the lifting end of the lifting drive mechanism 39, and two gripper modules 41 mounted on the lifting plate 40 at intervals. There is space between the two hanging plates 32 for the pick-and-place robot 38 to move into. The two gripper modules 41 on the same set of pick-and-place robots 38 are used to clamp the two ends of a section of the annular headband 98 between the two hanging plates 32.

[0044] In practical applications, after the feeding carrier 30 conveys the annular headband 98 to the loading position, the translation drive mechanism 36 drives the two sets of pick-and-place robots 38 to move above the annular headband 98. Since the annular headband 98 is fitted onto the two hanging plates 32 of the feeding carrier 30 and forms two belt segments, the two sets of pick-and-place robots 38 pick up these two belt segments respectively. Specifically, the lifting drive mechanism 39 drives the lifting plate 40, along with the two gripper modules 41, to descend, so that each belt segment of the annular headband 98 is located in the gripper of the two gripper modules 41. Then, the gripper of the two gripper modules 41 closes to clamp both ends of one belt segment of the annular headband 98, so that the four gripper modules 41 on the two sets of pick-and-place robots 38 clamp the annular headband respectively. At both ends of the two belt segments of 98, the lifting drive mechanism 39 drives the lifting plate 40 and the two gripper modules 41 to move upward, so that the two sets of pick-and-place robots 38 hold the annular headband 98 and move upward. Then, the translation drive mechanism 36 drives the two sets of pick-and-place robots 38 and the annular headband 98 to move above the cup-shaped mask body carried by the conveyor 3. At the same time, the spacing adjustment mechanism 37 drives the two sets of pick-and-place robots 38 to move away from each other, so that the annular headband 98 is stretched into a rectangle. Then, the two sets of pick-and-place robots 38 put the annular headband 98 stretched into a rectangle around the four positioning posts 17, so that the other two belt segments of the annular headband 98 are located on the two side ears of the mask body, so as to realize the automated feeding of the annular headband 98.

[0045] Specifically, the spacing adjustment mechanism 37 can adopt a transmission structure of synchronous belt and synchronous pulley. The two sets of pick-and-place manipulators 38 are fixedly connected to the upper and lower belt layers of the synchronous belt, respectively. During the forward and reverse rotation of the synchronous belt, the two sets of pick-and-place manipulators 38 move closer to or further away from each other to achieve the spacing adjustment of the two sets of pick-and-place manipulators 38.

[0046] In this embodiment, the ear-flipping welding device 7 includes a frame 42, an upper push-up ear-flipping mechanism 43, and two welding mechanisms 44. The frame 42 is mounted on the machine base 1, and the two welding mechanisms 44 are symmetrically and obliquely mounted on the frame 42. The upper push-up ear-flipping mechanism 43 is located below the upper conveying surface of the linear annular circulating conveying mechanism 2. The upper push-up ear-flipping mechanism 43 includes an upper push drive module 45, an upper push plate 46 mounted on the upper push end of the upper push drive module 45, two welding bottom molds 47 disposed on the upper push plate 46, and two ear-flipping plates 48 disposed on the upper push plate 46. The two welding bottom molds 47 are located below the upper conveying surface of the linear annular circulating conveying mechanism 2. Between the two flap plates 48, two welding mechanisms 44, two welding bottom molds 47 and two flap plates 48 are respectively set one by one. The welding bottom mold 47 is provided with a welding slope 49 on the side near the flap plate 48. The top of the flap plate 48 is provided with a welding through hole 50 corresponding to the welding slope 49. The welding end of the welding mechanism 44 can pass through the welding through hole 50. A through hole 51 is provided in the middle of the cavity 15. Two flap holes 16 are located at both ends of the through hole 51. The flap holes 16 communicate with the through hole 51. The welding bottom mold 47 and the flap plate 48 can pass through the through hole 51.

[0047] In practical applications, the conveyor 3 transports the cup-shaped mask body and the ring-shaped headband 98 to the space between the two welding mechanisms 44. Then, the upper drive module drives the upper push plate 46, along with the two welding bottom molds 47 and the two flap plates 48, to rise and penetrate through the through hole 51. This causes the welding slopes 49 of the two welding bottom molds 47 to abut against the inner wall of the cup-shaped mask body. The two flap plates 48 flip up the two side ears of the cup-shaped mask body. Then, the welding end of the welding mechanism 44 moves at an angle, penetrates through the welding through hole 50, and abuts against the welding slopes 49. The side ears, after being folded upwards, are welded to the cup-shaped mask body in a folded manner. This allows the side ears of the cup-shaped mask body to partially cover the section of the loop headband 98. Two welding mechanisms 44 weld the two side ears of the cup-shaped mask body respectively to fix the loop headband 98 to the two side ears of the cup-shaped mask body. This allows one loop headband 98 to form two headbands of the cup-shaped mask. Since the loop headband 98 can move relative to the side ears of the cup-shaped mask body, the length of the two headbands of the cup-shaped mask is adjustable. It should be noted that the side ears welded to the outer wall of the cup-shaped mask body will form side ear holes, through which the loop headband 98 passes.

[0048] In this embodiment, the flap welding device 7 further includes a pressing abutment mechanism 52 installed on the frame 42 and located between the two welding mechanisms 44. The pressing abutment mechanism 52 includes a vertical rod 53 installed on the frame 42, a pressing driver 54 installed on the vertical rod 53, and a pressing member 55 installed on the pressing drive end of the pressing driver 54. Two inclined pressure plates 56 are symmetrically and obliquely arranged on both sides of the pressing member 55. The inclined pressure plates 56 have clearance grooves 57 for the welding end of the welding mechanism 44 to pass through. The clearance grooves 57 are correspondingly arranged with the welding through hole 50.

[0049] Before the welding mechanism 44 welds the upward-curved side ears, the downward-pressing actuator 54 of the downward-pressing contact mechanism 52 drives the downward-pressing component 55 to move downward, so that the two inclined pressure plates 56 on the downward-pressing component 55 abut against the outer wall of the cup-shaped mask body. The welding inclined surface 49 and the inclined pressure plates 56 abut against the inner and outer walls of the cup-shaped mask body, respectively, to ensure the stability of the cup-shaped mask body and the flatness of the part of the cup-shaped mask body to be welded, thereby ensuring the quality of subsequent welding. Among them, the avoidance groove 57 on the inclined pressure plate 56 allows the welding end of the welding mechanism 44 to pass through, avoiding collision or interference between the welding mechanism 44 and the inclined pressure plate 56.

[0050] In this embodiment, the welding mechanism 44 includes a mounting base 58 inclinedly mounted on the frame 42, a slide 59 slidably connected to the mounting base 58, an ultrasonic welding head 60 mounted on the slide 59, a motion driver 61 mounted on the mounting base 58 and used to drive the slide 59 closer to or away from the transport carrier 3, a slider 62 slidably connected to the bottom surface of the slide 59, an inclined plate 63 mounted on the slider 62 and located below the ultrasonic welding head 60, and a tension spring 64 elastically connected to the slider 62 and the slide 59. The inclined plate 63 can penetrate the welding through hole 50 and abut against the welding inclined surface 49. Initially, the pressing surface of the inclined plate 63 extends beyond the welding surface of the ultrasonic welding head 60.

[0051] In practical applications, when the welding bevel 49 and the inclined pressure plate 56 abut against the inner and outer walls of the cup-shaped mask body, the moving driver 61 drives the slide 59, along with the ultrasonic welding head 60, the slider 62, and the inclined plate 63, to move towards the cup-shaped mask body at an angle. Since the pressure surface of the inclined plate 63 extends beyond the welding surface of the ultrasonic welding head 60, the pressure surface of the inclined plate 63 first contacts the upward-folded side ear and pushes the side ear to fold against the outer wall of the cup-shaped mask body. When the pressure surface of the inclined plate 63 presses the side ear against the outer wall of the cup-shaped mask body on the welding bevel 49, as the slide 59 moves, the inclined plate 63 will be compressed and stretch the tension spring 64. The ultrasonic welding head 60 will continue to move downward at an angle relative to the inclined plate 63, so that the welding surface of the ultrasonic welding head 60 passes through the welding hole 50 and welds the side ear in a folded manner to the outer wall of the cup-shaped mask body abutted by the welding bevel 49. This structural design allows the inclined plate 63 to first fold the side ear against the outer wall of the cup-shaped mask body, and then weld the side ear to the outer wall of the cup-shaped mask body through the ultrasonic welding head 60, thereby improving the welding quality of the side ear to the outer wall of the cup-shaped mask body.

[0052] In this embodiment, the cup-shaped mask production equipment with a ring headband also includes a pad printing device 65 mounted on the machine base 1 and located on one side of the linear ring-shaped circulating conveyor mechanism 2. The pad printing device 65 is located between the nose wire welding mechanism 5 and the upper ring headband device 6. In practical applications, the conveyor 3 transports the cup-shaped mask body with the nose wire welded to it to the pad printing device 65, and the pad printing device 65 transfers text and / or patterns and other identification information onto the outer wall of the cup-shaped mask body.

[0053] Specifically, the pad printing device 65 includes a pad printing base 66 mounted on the machine base 1, a fixing plate 67 mounted on the bottom of the pad printing base 66, a pad printing steel plate 68 mounted on the fixing plate 67, an ink cup 69 slidably connected to the upper surface of the pad printing steel plate 68, a reciprocating motion driver 70 mounted on the pad printing base 66 for driving the ink cup 69 to reciprocate, two side plates 71 symmetrically mounted in the middle of the pad printing base 66, a flipping driver 72 mounted on the pad printing base 66, a flipping seat 73 rotatably connected to the two side plates 71, and a flipping seat 73 mounted on the flipping seat 74. The system includes a telescopic driver 74, a printing head 75 mounted on the telescopic end of the telescopic driver 74, a lifting drive module 76 mounted on the machine base 1 and located below the upper conveying surface of the linear annular circulating conveyor mechanism 2, and a printing bottom mold 77 mounted on the lifting end of the lifting drive module 76 and capable of penetrating through the through hole 51. The top of the printing bottom mold 77 is provided with a printing abutment surface 78. The flip driver 72 is used to drive the flip seat 73 to flip. Preferably, the reciprocating motion driver 70, the telescopic driver 74 and the lifting drive module 76 can all be cylinders.

[0054] In practical applications, the conveyor 3 transports the cup-shaped mask body with the welded nose wire to the pad printing device 65. Initially, the pad printing head 75 faces downwards and is positioned opposite the pad printing steel plate 68. After the reciprocating motion driver 70 drives the ink cup 69 to reciprocate on the pad printing steel plate 68, the ink cup 69 carries the ink onto the pad printing markings on the pad printing steel plate 68. The telescopic driver 74 extends and drives the pad printing head 75 downwards until the pad printing head 75 contacts and picks up the ink from the pad printing markings on the pad printing steel plate 68. The rear telescopic driver 74 retracts and drives the pad printing head 75 to move upward and reset. Then, the flip driver 72 drives the flip seat 73 to flip the pad printing head 75 after it has been dipped in ink to a preset angle, so that the pad printing head 75 is opposite to the outer wall of the cup-shaped mask body carried by the conveyor 3. The telescopic driver 74 extends and drives the pad printing head 75 after it has been dipped in ink to approach the outer wall of the cup-shaped mask body, so that the pad printing head 75 abuts against the outer wall of the cup-shaped mask body until the pad printing of the cup-shaped mask body is completed. When the pad printing head 75 is printing on the cup-shaped mask body, the lifting drive module 76 drives the pad printing bottom mold 77 to move upward and pass through the through hole 51, so that the pad printing abutment surface 78 of the pad printing bottom mold 77 abuts against the inner side wall of the cup-shaped mask body. At this time, when the pad printing head 75 flips to align with the outer side wall of the cup-shaped mask body and the pad printing abutment surface 78 of the pad printing bottom mold 77, the telescopic drive 74 extends and drives the pad printing head 75 to move closer to the pad printing abutment surface 78 of the pad printing bottom mold 77 until the pad printing head 75 abuts against the outer side wall of the cup-shaped mask body, pressing the cup-shaped mask body tightly onto the pad printing abutment surface 78 of the pad printing bottom mold 77, so as to realize the pad printing on the outer side wall of the cup-shaped mask body and improve the quality of pad printing.

[0055] Furthermore, a pressure block 79 is vertically mounted above the linear annular circulating conveyor mechanism 2. The machine base 1 is equipped with a pressing frame, which is equipped with a pressing driver 80. The pressure block 79 is mounted on the pressing end of the pressing driver 80. The pressure block 79 is positioned opposite to the pad printing base mold 77. The pressing driver 80 is used to drive the pressure block 79 to move closer to or away from the linear annular circulating conveyor mechanism 2. Preferably, the pressing driver 80 can be a vertically downward cylinder. In practical applications, after the pad printing abutment surface 78 of the pad printing base mold 77 abuts against the inner wall of the cup-shaped mask body, the pressing driver 80 drives the pressure block 79 to move downward until the pressure block 79 presses the cup-shaped mask body tightly onto the pad printing base mold 77, thus pressing the cup-shaped mask body tightly. Then, the pad printing head 75 performs the pad printing work on the cup-shaped mask body, further improving the quality of the pad printing.

[0056] Furthermore, the flip drive 72 includes a hinge base 81, a lifting drive 82, a lifting seat 83, and a guide rod 84. The hinge base 81 is mounted on the top of the pad printing seat 66. The main body of the lifting drive 82 is hinged to the hinge base 81. The lifting seat 83 is mounted on the lifting end of the lifting drive 82. The guide rod 84 rotatably passes through the lifting seat 83. Both side plates 71 are provided with arc-shaped guide grooves 85. The two ends of the guide rod 84 are slidably disposed in the two arc-shaped guide grooves 85, allowing the guide rod 84 to move along the arc... The guide groove 85 slides, and the flipping seat 73 includes a flipping block 86, a rotating shaft 87, and an obtuse-angled swing arm 88. The two ends of the rotating shaft 87 are rotatably connected to the two side plates 71 respectively. The circle of the arc-shaped guide groove 85 is located on the central axis of the rotating shaft 87. One end of the obtuse-angled swing arm 88 is connected to the guide rod 84, and the corner of the obtuse-angled swing arm 88 is fitted outside the rotating shaft 87. The flipping block 86 is installed at the other end of the obtuse-angled swing arm 88, and the lifting driver 82 is installed on the flipping block 86. Specifically, the lifting driver 82 can be a cylinder.

[0057] In practical applications, initially, the pad printing head 75 faces downwards. After the pad printing head 75 picks up ink from the pad printing steel plate 68, the lifting driver 82 drives the lifting seat 83, along with the guide rod 84, to move downwards. Since the lifting seat 83 and the guide rod 84 are rotatably connected, and the main body of the lifting driver 82 is hinged to the hinge seat 81, the lifting driver 82 can make adaptive swings as the guide rod 84 moves downwards. This causes the guide rod 84 to slide downwards along the arc-shaped guide groove 85. The downward arc-shaped sliding of the guide rod 84 will drive the obtuse-angled swing arm 88 of the flip seat 73 to rotate around the central axis of the rotating shaft 87. The rotating obtuse-angled swing arm 88... The rotating block 86, along with the telescopic actuator 74 and the printing head 75, rotates until the printing head 75 is aligned with the printing abutment surface 78 of the printing base mold 77. The printing head 75 and the printing abutment surface 78 of the printing base mold 77 cooperate to transfer prints onto the outer wall of the cup-shaped mask body. After the transfer printing is completed, the lifting actuator 82 drives the lifting seat 83, along with the guide rod 84, to slide upward along the arc-shaped guide groove 85. The upward arc-shaped guide rod 84 drives the rotating seat 73 to reset and rotate. The reset rotating seat 73 drives the telescopic actuator 74 and the printing head 75 to reset and rotate until the printing head 75 rotates downward. This structural design can achieve the rotation of the printing head 75 while controlling the rotation angle range of the printing head 75 through the lifting actuator 82 to meet the required printing angle of different cup-shaped mask bodies.

[0058] Furthermore, rollers 89 are rotatably connected to both ends of the guide rod 84, and the rollers 89 roll against the inner wall of the arc-shaped guide groove 85. As the guide rod 84 slides along the arc-shaped guide groove 85, the rollers 89 roll on the inner wall of the arc-shaped guide groove 85 to reduce the frictional resistance and wear of the guide rod 84, making the arc-shaped sliding of the guide rod 84 smoother and more stable.

[0059] Specifically, the unloading device 11 includes an unloading frame 90 mounted on the machine base 1 and mounted above the linear circular conveyor mechanism 2, an output mechanism 91 mounted on the machine base 1 and located on one side of the linear circular conveyor mechanism 2, a translation drive module 92 mounted on the top of the unloading frame 90, a lifting drive unit 93 mounted on the translation end of the translation drive module 92, a movable seat 94 mounted on the lifting end of the lifting drive unit 93, a double-output telescopic device 95 horizontally mounted on the movable seat 94, and two output ends respectively mounted on the double-output telescopic device 95. The two sets of extraction hooks 96 and at least two pressure rods 97 respectively installed on the movable seat 94 and located on both sides of the double-output telescopic joint 95 are used to press down the carrier plate 14 of the conveyor 3. The double-output telescopic joint 95 is used to drive the two sets of extraction hooks 96 to move closer or further away from each other. The two sets of extraction hooks 96 are respectively set to correspond one-to-one with the two flap holes 16. Furthermore, the double-output telescopic joint 95 can be a double-output cylinder. The translation drive module 92 and the lifting drive unit 93 can both be cylinders. The number of pressure rods 97 is four, and the four pressure rods 97 are distributed in a rectangular shape.

[0060] In practical applications, when the conveyor 3 transports the cup-shaped mask between the unloading device 11 and the unloading top opening mechanism 23, the lifting drive unit 93 drives the moving seat 94, along with the double-output telescopic device 95, two sets of extraction hooks 96, and all the pressure rods 97, to move downwards until the two sets of extraction hooks 96 extend into the two flap holes 16 respectively, and all the pressure rods 97 press against the edge of the carrier plate 14 of the conveyor 3. Then, the top end of the unloading top opening mechanism 23 pushes upwards and drives the rotating clamping device 19 to open relative to the carrier plate 14. Then, the double-output telescopic device 95 drives the two sets of extraction hooks 96 to move closer to each other, so that the cup-shaped opening... The mask is positioned between two sets of extraction hooks 96, which support the cup-shaped mask. Then, the lifting drive unit 93 drives the dual-output telescopic device 95, along with the two sets of extraction hooks 96 and the cup-shaped mask, to move upwards, detaching the cup-shaped mask from the conveyor carrier 3. Finally, the translation drive module 92 drives the lifting drive unit 93, the moving seat 94, the dual-output telescopic device 95, the two sets of extraction hooks 96, and the cup-shaped mask to move horizontally above the output mechanism 91. The dual-output telescopic device 95 drives the two sets of extraction hooks 96 to move away from each other, releasing the cup-shaped mask so that it is placed on the conveyor mechanism, which then outputs the cup-shaped mask. Because the pressure rod 97 presses downwards against the conveyor carrier 3 when the top opening mechanism 23 rotates the clamping fastener 19, the conveyor carrier 3 will not detach from the linear annular circulating conveyor mechanism 2, preventing the conveyor carrier 3 and the circulating conveying surface of the linear annular circulating conveyor mechanism 2 from being subjected to upward pulling force.

[0061] It should be noted that the annular headband 98 sleeved on the four positioning posts 17 does not affect the normal rotation of the rotating pressure member 19, or the rotating pressure member 19 will not interfere with the removal of the cup-shaped mask with the annular headband 98 fixed on it. Of course, the cup-shaped mask with the annular headband 98 fixed on it can also be removed before the rotating pressure member 19 is opened. Because the rotating pressure member 19 is elastically connected to the conveyor 3 via a torsion spring, when the cup-shaped mask with the annular headband 98 fixed on it is removed upwards, as the cup-shaped mask moves upwards, the cup-shaped mask will cause the rotating pressure member 19 to open and rotate slightly until the cup-shaped mask is completely removed. Then, the rotating pressure member 19 will close its rotation under the action of the torsion spring's rebound force. Alternatively, the rotating pressure member 19 can be opened and rotated at the same time as the cup-shaped mask with the annular headband 98 fixed on it is removed upwards.

[0062] All technical features in this embodiment can be freely combined according to actual needs.

[0063] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
