Description

Technical Field

[0001] This invention relates to a machine tool, and more particularly to a humidifier assembly machine. Background Technology

[0002] The humidifier is a crucial component of a ventilator, its function being to warm and humidify inhaled air. A humidifier typically consists of an aluminum base cover, a plastic top cover attached to the top of the base cover, a sealing ring between the top and bottom covers, and a float inside the cavity formed by the base and bottom covers. These various parts are manufactured on different production lines and then assembled by workers. However, in production, it is difficult to further improve worker assembly efficiency and labor costs are rising, hindering improvements in overall production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a humidifier assembly machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is:

[0005] A humidifier assembly machine includes a conveyor line extending in a left-right direction, with multiple positioning discs spaced apart on the conveyor surface of the conveyor line. It also includes, sequentially arranged along the conveyor line's conveying direction: a chassis feeder for feeding material into one of the positioning discs; a sealing ring feeder for feeding material into one of the positioning discs; a float feeder for feeding material into one of the positioning discs; a top cover feeder for feeding material into one of the positioning discs; and a riveting mechanism including a feeding hand and a riveting part, the feeding hand having a feeding end that can move back and forth between one of the positioning discs and the riveting part.

[0006] This technical solution has at least the following beneficial effects: Multiple positioning discs for placing and positioning workpieces are arranged at intervals on the conveyor surface of the conveyor line. The conveyor line drives these positioning discs to rotate cyclically. As the positioning discs move, they pass sequentially through a chassis feeder, a sealing ring feeder, a float feeder, and a top cover feeder. The chassis feeder first feeds the chassis into the positioning discs; the sealing ring feeder feeds the sealing rings into the chassis; the float feeder feeds the floats into the chassis; and the top cover feeder feeds the top cover into the chassis. The top cover is connected to the chassis via the sealing rings, and the floats are located within the cavity formed by the top cover and chassis. At this point, the feeding and preliminary assembly of multiple components are completed. Finally, the unloading operator moves the entire assembly to the riveting section, where the chassis and top cover are riveted together. This mechanical operation reduces manual labor, improving the stability and efficiency of the entire assembly process, thereby improving the assembly quality of the humidifier, reducing labor costs, and increasing production efficiency.

[0007] As a further improvement to the above technical solution, the chassis feeder includes a feeding frame, a fixed frame, a first translation drive, a first lifting drive, and a first suction cup. The feeding frame has a feeding cavity inside. The first translation drive is connected to the fixed frame. The first translation drive can drive the first lifting drive to move back and forth above the feeding cavity and above a positioning plate. The first suction cup is connected to the first lifting drive. The first lifting drive can drive the first suction cup to move up and down. The chassis are stacked and placed in the loading cavity formed by the loading rack. When a chassis needs to be loaded, the first translation drive first moves the first suction cup to the top of the loading cavity. Then, the first lifting drive moves the first suction cup down into the loading cavity, where the first suction cup picks up the chassis located at the top. Next, the first lifting drive moves the first suction cup up to reset. The first translation drive moves the first suction cup to the top of the positioning plate on the conveying surface. Finally, the first lifting drive moves the first suction cup down to load the chassis onto the positioning plate, completing the loading. When the conveying surface moves and moves the next positioning plate to the loading position of the chassis feeder, the chassis feeder repeats the operation to load the chassis one by one.

[0008] As a further improvement to the above technical solution, the loading rack includes an outer frame and a tray located within the outer frame. The outer frame and the tray form the loading cavity. A lifting drive is connected within the outer frame, and the tray is connected to the lifting drive. The lifting drive can move the tray up and down. The outer frame is used to surround and limit the sides of the chassis. When the first suction cup picks up the chassis located at the top, the lifting drive drives the tray to rise, raising the stacked chassis as a whole. At this time, the height the tray rises can be the thickness of one chassis. Thus, when the first lifting drive drives the first suction cup to load the next chassis, it can be lowered by the same height, eliminating the need to adjust the height of the first suction cup's downward movement each time, thus achieving more stable loading of the first suction cup.

[0009] As a further improvement to the above technical solution, the sealing ring feeder includes a limiting frame, a surrounding plate, a material feeding hand, and a transfer hand. The surrounding plate is connected to the top side of the limiting frame, and a material storage cavity is provided inside the surrounding plate. A limiting groove is provided on the top side of the limiting frame, and a notch is provided on the bottom of the surrounding plate directly opposite the limiting groove. A slot is provided on the top side of the limiting frame between the material storage cavity and the limiting groove. The material feeding hand has a material feeding end that can reciprocate between the slot and the slot. The transfer hand has a transfer end that can move back and forth between the limiting groove and a positioning plate. The sealing rings are stacked vertically in the storage cavity. When it is necessary to feed the sealing rings, the feeding end of the feeding hand is first moved into the storage cavity and placed against the inner ring of the bottom sealing ring. Then, the feeding end moves along the slot to the limiting groove, and the bottom sealing ring is pushed out of the storage cavity from the notch at the bottom of the enclosure plate. The sealing ring is then moved into the limiting groove for positioning. At this time, the transfer end of the transfer hand moves into the limiting groove and takes out the sealing ring in the limiting groove and puts it into the base of the positioning plate. This completes the feeding of the sealing rings and better ensures that only one sealing ring is transferred at a time, and the sealing ring is stably transferred into the positioning plate.

[0010] As a further improvement to the above technical solution, the float feeder includes a vibratory feeder, a mounting frame, a second translation drive, a second lifting drive, and a second suction cup. The second translation drive is connected to the mounting frame, and the second lifting drive is connected to the second translation drive. The second translation drive can drive the second lifting drive to move back and forth between the output port of the vibratory feeder and the top of a positioning plate. The second suction cup is connected to the second lifting drive, and the second lifting drive can drive the second suction cup to move up and down. The floats are stored in the vibratory feeder. The vibratory feeder vibrates and discharges the floats one by one from the output port of the vibratory feeder. At this time, the second translation drive moves the second suction cup to above the output port of the vibratory feeder. The second lifting drive moves the second suction cup down and picks up the float located at the output port of the vibratory feeder. Then, the second lifting drive moves the float up away from the vibratory feeder and the second translation drive moves the float to above the positioning plate with the base. Finally, the second lifting drive moves the float down to the positioning plate, thus completing the feeding of the floats. When the conveyor line moves the next positioning plate to the feeding position of the float feeder, the float feeder repeats the action to feed the float to the next positioning plate.

[0011] As a further improvement to the above technical solution, the upper cover feeder includes a storage rack, a base frame, a third translation drive, a third lifting drive, and a third suction cup. The storage rack has a storage cavity inside. The third translation drive is connected to the base frame. The third translation drive can drive the third lifting drive to move back and forth above the storage cavity and above a positioning plate. The third suction cup is connected to the third lifting drive. The third lifting drive can drive the third suction cup to move up and down. The top covers are stacked vertically within the storage cavity formed by the storage rack. When a top cover needs to be loaded, the third translation drive first moves the third suction cup to the top of the storage cavity, then the third lifting drive moves the third suction cup down into the storage cavity, where the third suction cup picks up the top cover. Next, the third lifting drive moves the third suction cup up to reset, and the third translation drive moves the third suction cup to the top of the positioning plate with the base on the conveying surface. Finally, the third lifting drive moves the third suction cup down, and the third suction cup places the top cover on the base, completing the loading. When the conveying surface moves and moves the next positioning plate to the loading position of the top cover feeder, the top cover feeder repeats the action to load the top covers one by one.

[0012] As a further improvement to the above technical solution, the riveting mechanism also includes a riveting frame, a first rotary drive, and a turntable. The turntable is rotatably connected to the top side of the riveting frame, and the first rotary drive is drive-connected to the turntable. A workpiece disk is rotatably connected to the top side of the turntable, and multiple workpiece disks are arranged in a circular array around the center of the turntable. The unloading operator loads the humidifier, which has been loaded into a positioning disk at the end of the conveyor line, into a workpiece disk on the top side of the turntable. Then, the first rotary drive drives the turntable, which rotates the workpiece disk with the humidifier to the riveting part. The riveting part further rivets the base and the top cover together. At this time, the rotation of the workpiece disk is used to adjust the posture of the entire humidifier, allowing the riveting part to directly complete the riveting connection between the two on the workpiece disk, thereby completing the assembly and fixation of the entire humidifier. In this way, the turntable provides multiple rotating workpiece disks as pre-riveting loading stations and riveting stations, reducing the waiting time for loading workpieces before riveting and further improving the overall production efficiency.

[0013] As a further improvement to the above technical solution, the riveting part includes a pressure frame, a fourth lifting drive, a second rotary drive, a pressure die, a fourth translational drive, a third rotary drive, and a pressure roller. The fourth lifting drive and the fourth translational drive are both connected to the pressure frame. The second rotary drive is connected to the fourth lifting drive, and the fourth lifting drive can drive the second rotary drive to move up and down above the workpiece disk. The pressure die is connected to the second rotary drive, and the second rotary drive can drive the pressure die to rotate. The second rotary drive is connected to the fourth translational drive, and the fourth translational drive can drive the second rotary drive to move closer to or away from the workpiece disk. The pressure roller is connected to the third rotary drive, and the third rotary drive can drive the pressure roller to rotate. The turntable rotates the workpiece disc with the humidifier to below the mold. The fourth lifting drive moves the mold down, pressing the top cover firmly onto the chassis. Then, the fourth translation drive moves the pressure roller closer to the humidifier and presses it against the outside of the chassis. At the same time, the second rotation drive rotates the mold, causing the entire positioning disc to rotate to adjust the placement of the humidifier. This gradually presses the outer edge of the chassis inward, so that the outer edge of the chassis rivets the outer edge of the top cover together. After completion, the fourth translation drive moves the pressure roller away from the humidifier to reset, while the fourth lifting drive moves the mold up to reset.

[0014] As a further improvement to the above technical solution, the riveting mechanism also includes a unloading hand, which comprises an unloading robotic arm and an unloading suction cup, the suction cup being connected to the unloading robotic arm. After the riveting part rivets the upper cover and the chassis together, the turntable rotates, moving the assembled humidifier away from the riveting part. Then, the unloading robotic arm drives the unloading suction cup to move to the turntable, using the suction cup to pick up the assembled humidifier and remove it from the turntable, thus unloading the assembled humidifier.

[0015] As a further improvement to the above technical solution, the unloading hand includes an unloading robotic arm and an unloading clamp, the unloading clamp being connected to the unloading robotic arm and serving as the unloading end. The unloading robotic arm drives the unloading clamp to the positioning plate at the end of the conveyor line, using the unloading clamp to clamp the entire humidifier that has been loaded out of the positioning plate, and then the unloading robotic arm drives it to move into the workpiece plate on the turntable, thus realizing the transfer of the humidifier before riveting.

[0026] Reference Figure 1 The humidifier assembly machine includes a conveyor line 100 extending in a left-right direction. The conveyor line 100 can be a belt conveyor or a chain conveyor. Multiple positioning discs are arranged at intervals on the conveying surface of the conveyor line 100. In addition, a chassis feeder 200, a sealing ring feeder 300, a float feeder, a top cover feeder, and a riveting mechanism are arranged sequentially along the conveying direction of the conveyor line 100. The chassis feeder 200 can feed materials into one of the positioning discs, the sealing ring feeder 300 can feed materials into one of the positioning discs, the float feeder can feed materials into one of the positioning discs, and the top cover feeder can feed materials into one of the positioning discs. The riveting mechanism includes a feeding hand and a riveting part 410. The feeding hand has a feeding end that can move back and forth between one of the positioning discs and the riveting part 410.

[0027] As described above, multiple positioning discs for placing and positioning workpieces are arranged at intervals on the conveying surface of the conveyor line 100. The conveyor line 100 drives the multiple positioning discs to rotate cyclically. When the positioning discs move, they pass sequentially through the chassis feeder 200, the sealing ring feeder 300, the float feeder, and the top cover feeder. The chassis feeder 200 first feeds the chassis into the positioning discs, the sealing ring feeder 300 feeds the sealing rings into the chassis, the float feeder feeds the floats into the chassis, and the top cover feeder feeds the top cover. The top cover is fed into the chassis, and the top cover is connected to the chassis through a sealing ring. The float is located in the cavity formed by the top cover and the chassis. At this time, the feeding and preliminary assembly of multiple parts are completed. Finally, the unloading operator moves the whole assembly into the riveting part 410, and the chassis and top cover are riveted together. This mechanical operation reduces manual operation, which helps to improve the stability and efficiency of the entire assembly process, thereby improving the assembly quality of the humidifier, reducing labor costs, and improving production efficiency.

[0028] The chassis feeder 200 is mainly used to feed chassis to the positioning plate on the conveyor line 100, such as... Figure 2As shown, in this embodiment, the chassis feeder 200 includes a feeding frame, a fixed frame 220, a first translation drive 230, a first lifting drive 240, and a first suction cup 250. The feeding frame has a feeding cavity inside. The fixed frame 220 can be a gantry structure spanning between the feeding frame and the conveyor line 100. The first translation drive 230 is connected to the fixed frame 220. The first translation drive 230 can drive the first lifting drive 240 to move back and forth above the feeding cavity and above a positioning plate. The first suction cup 250 is connected to the first lifting drive 240. The first lifting drive 240 can drive the first suction cup 250 to move up and down. In practical applications, the first suction cup 250 is a vacuum suction cup, which is connected to a vacuum pump. By forming a negative pressure on the suction surface of the first suction cup 250, the chassis can be suctioned and positioned. The chassis are stacked and placed in the loading cavity formed by the loading rack. When a chassis needs to be loaded, the first translation drive 230 first moves the first suction cup 250 to the top of the loading cavity. Then, the first lifting drive 240 moves the first suction cup 250 down into the loading cavity, where the first suction cup 250 picks up the chassis located at the top. Next, the first lifting drive 240 moves the first suction cup 250 up to reset. The first translation drive 230 moves the first suction cup 250 to the top of the positioning plate on the conveying surface. Finally, the first lifting drive 240 moves the first suction cup 250 down to load the chassis onto the positioning plate, completing the loading. When the conveying surface moves and moves the next positioning plate to the loading position of the chassis feeder 200, the chassis feeder 200 repeats the operation to load the chassis one by one.

[0029] When the chassis at the top is removed, the overall height of the stacked arrangement will decrease. When the first suction cup 250 is loaded again, it needs to move down more to pick up the first suction cup 250 at the top. In order to better pick up and position the chassis, in this embodiment, the loading rack includes an outer frame 211 and a tray 212 located inside the outer frame 211. The loading cavity is formed between the outer frame 211 and the tray 212. A lifting drive 260 is connected inside the outer frame 211. The tray 212 is connected to the lifting drive 260. The lifting drive 260 can drive the tray 212 to move up and down. The outer frame 211 is used to surround and limit the sides of the chassis. After the first suction cup 250 picks up the chassis located at the top, the lifting drive 260 drives the pallet 212 to rise, raising the stacked chassis as a whole. At this time, the height of the pallet 212 can be equal to the thickness of one chassis. Thus, when the first lifting drive 240 drives the first suction cup 250 to load the next chassis, it can be lowered by the same height, eliminating the need to adjust the height of the first suction cup 250 each time, thus achieving more stable loading of the first suction cup 250. In practical applications, the lifting drive 260 is mainly used to provide driving force for vertical movement. It has various structural forms, such as cylinders and hydraulic cylinders. In this embodiment, an electric lead screw can be used to improve the accuracy of the vertical adjustment of the pallet 212.

[0030] The sealing ring feeder 300 is mainly used to feed sealing rings into the positioning plate on the conveyor line 100. Because the sealing ring is a ring-shaped elastic structure, its contact area is small and it is relatively soft. When the sealing rings are stacked and picked up one by one, the large area of ​​negative pressure adsorption can easily cause the sealing rings located below to be sucked out simultaneously. Therefore, in this embodiment, as... Figure 3As shown, the sealing ring feeder 300 includes a limiting frame 310, a surrounding plate 320, a material feeder 330, and a transfer hand 340. The surrounding plate 320 is connected to the top side of the limiting frame 310. A storage cavity is provided inside the surrounding plate 320. A limiting groove is provided on the top side of the limiting frame 310. A notch is provided on the bottom of the surrounding plate 320 directly opposite the limiting groove. A slot is provided on the top side of the limiting frame 310 between the storage cavity and the limiting groove. The material feeder 330 has a material feeder end that can reciprocate between the slot. The transfer hand 340 has a transfer end that can move back and forth between the limiting groove and a positioning plate. The sealing rings are stacked vertically in the storage cavity. When it is necessary to feed the sealing rings, the feeding end of the feeding hand 330 is first moved into the storage cavity and placed against the inner ring of the bottom sealing ring. Then, the feeding end moves along the slot to the limiting groove, and the bottom sealing ring is pushed out of the storage cavity from the notch at the bottom of the enclosure plate 320. The sealing ring is then moved into the limiting groove for positioning. At this time, the transfer end of the transfer hand 340 moves into the limiting groove and takes out the sealing ring in the limiting groove and puts it into the base of the positioning plate. This completes the feeding of the sealing rings and better ensures that only one sealing ring is transferred at a time, and the sealing ring is stably transferred into the positioning plate.

[0031] The material-picking end of the material-picking hand 330 needs to achieve vertical movement and horizontal reciprocating motion. In this embodiment, the material-picking hand 330 includes a fifth translation drive, a fifth lifting drive, and a material-picking rod. The fifth translation drive is connected to the bottom side of the limit frame 310, and the fifth lifting drive is connected to the fifth translation drive. The fifth translation drive can drive the fifth lifting drive to reciprocate along the length extension direction of the slot. The material-picking rod is connected to the fifth lifting drive. The fifth lifting drive can drive the material-picking rod to extend upward into the slot or downward out of the slot. The material-picking rod serves as the material-picking end. When it is necessary to remove the sealing ring located at the bottom, the fifth translation drive first moves the material-pulling rod to the bottom of the storage cavity, and then the fifth lifting drive moves the material-pulling rod upward and extends into the slot. Next, the fifth translation drive moves the material-pulling rod in the slot, and the top of the material-pulling rod abuts against the inner ring of the sealing ring located at the bottom, and moves the sealing ring into the limiting groove, thus realizing the removal of the sealing ring. After completion, the fifth lifting drive moves the material-pulling rod downward out of the slot to reset, completing the removal action.

[0032] The transfer hand 340 can adopt the same movement method as the first suction cup 250, including a transfer frame, a sixth translation drive, a sixth lifting drive, and a fourth suction cup. The transfer frame is a gantry structure spanning between the limiting frame 310 and the conveyor line 100. The sixth translation drive is connected to the transfer frame, and the sixth lifting drive is connected to the sixth translation drive. The sixth translation drive can drive the sixth lifting drive to move in a straight line. The fourth suction cup is connected to the sixth lifting drive, and the sixth lifting drive can drive the fourth suction cup to move up and down. The sixth translation drive and the sixth lifting drive are used to provide driving force for the fourth suction cup to reciprocate in the horizontal and vertical directions, respectively, so that the fourth suction cup can move down into the limiting groove, then pick up the sealing ring, transfer the sealing ring to the positioning plate on the conveyor line 100, and then move down again to place the sealing ring in the base of the positioning plate. In practical applications, the fourth suction cup is also a vacuum suction cup, which is connected to a vacuum pump. By creating negative pressure on the suction surface of the fourth suction cup, the sealing ring is picked up and positioned.

[0033] The float feeder is mainly used to feed floats onto the positioning discs on the conveyor line 100. In this embodiment, the float feeder includes a vibratory plate 510, a mounting frame 520, a second translation drive 530, a second lifting drive 540, and a second suction cup 550. The mounting frame 520 is a gantry structure spanning between the vibratory plate 510 and the conveyor line 100. The second translation drive 530 is connected to the mounting frame 520, and the second lifting drive 540 is connected to the second translation drive 530. The second translation drive 530 can drive the second lifting drive 540 to move back and forth between the output port of the vibratory plate 510 and the top of one of the positioning discs. The second suction cup 550 is connected to the second lifting drive 540, and the second lifting drive 540 can drive the second suction cup 550 to move up and down. In practical applications, the second suction cup 550 is also a vacuum suction cup, which is connected to a vacuum pump. By forming a negative pressure on the adsorption surface of the second suction cup 550, the float can be sucked up and positioned. The floats are stored in the vibratory feeder 510. The vibratory feeder 510 vibrates and discharges the floats one by one from the output port of the vibratory feeder 510. At this time, the second translation drive 530 drives the second suction cup 550 to move above the output port of the vibratory feeder 510. The second lifting drive 540 drives the second suction cup 550 to move down and pick up the float located at the output port of the vibratory feeder 510. Then, the second lifting drive 540 drives the float to move up away from the vibratory feeder. The second translation drive 530 drives the float to move above the positioning plate with the base. Finally, the second lifting drive 540 drives the float to move down onto the positioning plate, thus completing the feeding of the floats. When the conveyor line 100 drives the next positioning plate to the feeding position of the float feeder, the float feeder repeats the action to feed the float to the next positioning plate.

[0034] The cover feeder is mainly used to feed the cover onto the positioning plate on the conveyor line 100. It has various structural forms. In this embodiment, the cover feeder includes a storage rack 610, a base frame 620, a third translation drive 630, a third lifting drive 640, and a third suction cup 650. The storage rack 610 has a storage cavity inside. The third translation drive 630 is connected to the base frame 620. The third translation drive 630 can drive the third lifting drive 640 to move back and forth above the storage cavity and above one of the positioning plates. The third suction cup 650 is connected to the third lifting drive 640. The third lifting drive 640 can drive the third suction cup 650 to move up and down. In practical applications, the third suction cup 650 is also a vacuum suction cup, connected to a vacuum pump. By creating negative pressure on the suction surface of the third suction cup 650, the cover is sucked up and positioned. The top covers are stacked vertically within the storage cavity formed by the storage rack 610. When a top cover needs to be loaded, the third translation drive 630 first moves the third suction cup 650 to the top of the storage cavity. Then, the third lifting drive 640 moves the third suction cup 650 down into the storage cavity, where the third suction cup 650 picks up the top cover. Next, the third lifting drive 640 moves the third suction cup 650 up to reset it. The third translation drive 630 moves the third suction cup 650 to the top of the positioning plate with the chassis on the conveying surface. Finally, the third lifting drive 640 moves the third suction cup 650 down, and the third suction cup 650 places the top cover on the chassis, completing the loading. When the conveying surface moves and moves the next positioning plate to the loading position of the top cover feeder, the top cover feeder repeats the operation to load the top covers one by one.

[0035] When the top cover is removed, the overall height of the stacked arrangement will decrease. When the third suction cup 650 is loading again, it needs to move down more to pick up the top cover. In order to better pick up and position the top cover, in this embodiment, the storage rack 610 includes a storage frame and a top plate located in the storage frame. The storage cavity is formed between the storage frame and the top plate. A lifting drive is connected in the storage frame. The top plate is connected to the lifting drive. The lifting drive can drive the top plate to move up and down. The storage frame is used to surround and limit the sides of the top cover. After the third suction cup 650 picks up the top cover located at the topmost side, the lifting drive drives the top plate to rise, lifting the stacked top covers as a whole. At this time, the height of the top plate can be the thickness of one top cover. Thus, when the third lifting drive 640 drives the third suction cup 650 to load the next top cover, it can be lowered by the same height. It is not necessary to adjust the height of the third lifting drive 640 driving the third suction cup 650 to move down each time, which can better achieve stable loading of the third suction cup 650. In practical applications, the lifting drive is mainly used to provide driving force for vertical movement. Its structural form is various, such as cylinder, hydraulic cylinder, etc. In this embodiment, an electric lead screw can be used to improve the accuracy of the vertical adjustment of the top plate.

[0036] In the above embodiment, the humidifier located at the end of the conveyor line 100 is transferred by the unloading operator to the riveting part 410, and then the riveting part 410 rivets the humidifier together. This process generates a waiting time before riveting and a waiting time after riveting. To improve production efficiency, such as... Figure 4As shown, in this embodiment, the riveting mechanism further includes a riveting frame 421, a first rotary drive, and a turntable 422. The turntable 422 is rotatably connected to the top side of the riveting frame 421, and the rotation axis of the turntable 422 extends in the vertical direction. The first rotary drive is drively connected to the turntable 422. A workpiece disk 423 is rotatably connected to the top side of the turntable 422. Multiple workpiece disks 423 are arranged in a circular array around the center of the turntable 422. The rotation axis of the workpiece disks 423 extends in the vertical direction. In practical applications, the workpiece disks 423 have the same function as the positioning disk, mainly used to limit the humidifier. The unloading operator loads the humidifier, which has been loaded into a positioning plate at the end of the conveyor line 100, into a workpiece plate 423 on the top side of the turntable 422. Then, the first rotation drive drives the turntable 422, which rotates the workpiece plate 423 containing the humidifier to the riveting part 410. The riveting part 410 further rivets the chassis to the top cover. At this time, the rotation of the workpiece plate 423 is used to adjust the posture of the entire humidifier, so that the riveting part 410 can directly complete the riveting connection between the two on the workpiece plate 423, thereby completing the assembly and fixation of the entire humidifier. In this way, the turntable 422 provides multiple rotating workpiece plates 423 as a pre-riveting loading station and a riveting station, reducing the waiting time for loading workpieces before riveting and further improving the overall production efficiency.

[0037] As a specific structural embodiment of the riveting part 410, the riveting part 410 includes a pressure frame 411, a fourth lifting drive, a second rotation drive, a pressure mold 412, a fourth translation drive, a third rotation drive, and a pressure roller 413. The fourth lifting drive and the fourth translation drive are both connected to the pressure frame 411. The second rotation drive is connected to the fourth lifting drive. The fourth lifting drive can drive the second rotation drive to move up and down above the workpiece disk 423. The pressure mold 412 is connected to the second rotation drive. The second rotation drive can drive the pressure mold 412 to rotate. The second rotation drive is connected to the fourth translation drive. The fourth translation drive can drive the second rotation drive to move closer to or away from the workpiece disk 423. The pressure roller 413 is connected to the third rotation drive. The third rotation drive can drive the pressure roller 413 to rotate. In order to improve the positioning effect of the pressure mold 412 on the upper cover, the bottom side of the pressure mold 412 can be provided with a groove structure adapted to the upper cover to better limit and press the upper cover. The turntable 422 rotates the workpiece disc 423 with the humidifier to below the mold 412. The fourth lifting drive drives the mold 412 to move down, pressing the upper cover onto the chassis. Then, the fourth translation drive drives the pressure roller 413 to approach the humidifier and presses it against the outside of the chassis. At the same time, the second rotation drive drives the mold 412 to rotate, causing the entire positioning disc to rotate to adjust the placement of the humidifier. This gradually presses the outer edge of the chassis inward, so that the outer edge of the chassis rivets the outer edge of the upper cover together. When the pressure roller 413 applies pressure to the outer edge of the chassis, it mainly relies on the outer edge of the pressure roller 413 to abut against the outer edge of the chassis to apply force, thereby causing the outer edge of the chassis to bend and deform inward. After completion, the fourth translation drive drives the pressure roller 413 to move away from the humidifier and reset, while the fourth lifting drive also drives the mold 412 to move up and reset.

[0038] After the humidifier is riveted, the turntable 422 rotates the riveted humidifier out. At this time, the humidifier can be manually removed from the workpiece tray 423. In order to further improve the overall automation level, in this embodiment, the riveting mechanism also includes a unloading hand, which includes an unloading robotic arm 431 and an unloading suction cup 432. The unloading suction cup 432 is connected to the unloading robotic arm 431. In practical applications, the unloading robotic arm 431 is a robotic arm with multiple degrees of freedom, and the unloading suction cup 432 is also a vacuum suction cup, which is connected to a vacuum pump. By forming a negative pressure on the adsorption surface of the unloading suction cup 432, the assembled humidifier can be picked up and positioned. After the riveting part 410 rivets the upper cover and the chassis together, the turntable 422 rotates to move the assembled humidifier away from the riveting part 410. Then, the unloading robot arm 431 drives the unloading suction cup 432 to move to the turntable 422. The unloading suction cup 432 picks up the assembled humidifier and moves it out of the turntable 422. In this way, the assembled humidifier can be unloaded.

[0039] The humidifier, after being loaded, has poor stability. Therefore, a stable clamping structure is required when it is transferred to the riveting part 410. In this embodiment, the unloading hand includes an unloading robotic arm 441 and an unloading clamp 442. The unloading clamp 442 is connected to the unloading robotic arm 441 and is the unloading end. In practical applications, the unloading robotic arm 441 is also a robotic arm with multiple degrees of freedom, which can drive the unloading clamp 442 to move in multiple directions. The unloading hand consists of two clamping plates driven by pneumatic grippers. In use, the pneumatic grippers can drive the two clamping plates to move closer or further apart. The middle of each clamping plate has an opening structure to avoid the middle position of the chassis and the top cover. In use, one clamping plate is placed against the two sides of the bottom surface of the chassis, and the other clamping plate is placed against the two sides of the top surface of the top cover. When the two clamping plates are close to each other, the entire humidifier is lifted and clamped up and down. The unloading robot arm 441 drives the unloading clamp 442 to the positioning plate at the end of the conveyor line 100. The unloading clamp 442 is used to clamp the humidifier that has been loaded out of the positioning plate, and the unloading robot arm 441 drives it to move into the workpiece plate 423 on the turntable 422. This realizes the transfer of the humidifier before riveting.

[0040] The first lifting drive 240, the first translation drive 230, the second lifting drive 540, the second translation drive 530, the third lifting drive 640, the third translation drive 630, the fourth lifting drive, and the fourth translation drive are all used to provide driving force for reciprocating movement in a linear direction. They have various structural forms, such as cylinders, hydraulic cylinders, or electric lead screws. The first rotary drive and the second rotary drive are both used to provide driving force for rotary movement, and they have various structural forms, such as drive motors or rotary cylinders.
