Description

Technical Field

[0001] The invention belongs to the technical field related to the production and processing of respiratory filters, and in particular relates to an assembly device for a composite respiratory filter. Background Art

[0002] A respiratory filter is a filter used in a breathing circuit. It has different degrees of biological filtration, heating, and the function of reducing the generation of net raw water, preventing the collapse of small airways and atelectasis, and can reduce the contamination of microorganisms in the breathing circuit and reduce nosocomial infections. When critically ill patients are treated with a ventilator, the use of an artificial nose can also reduce the use rate of lung complications. Patients with postoperative tracheotomy should also use an artificial nose, which has a good effect on humidifying and heating the inhaled gas and reducing lung complications. It can simulate the function of the nose, collect and retain the heat and water vapor in the exhaled gas, and when inhaling, the gas is brought into the airway in a warm and humidified state through the artificial nose, ensuring that the airway is effectively and appropriately humidified. At the same time, it has a certain filtering effect on bacteria, which can reduce the risk of bacterial contamination of the pipeline.

[0003] During the production and assembly of existing respiratory filters, the components produced are often installed manually. This method is not only time-consuming and labor-intensive, but also has a very low assembly efficiency and cannot meet the requirements of rapid and accurate product production.

When the breathing filter needs to be assembled, the transmission rod is driven to rotate by an intermittent driving mechanism, so that the turntable drives the baffle to rotate intermittently under the storage barrel, and the baffle blocks the outlet of the storage barrel during the rotation of the baffle, and when the baffle stops rotating, the through opening of the baffle is aligned with the outlet of the storage barrel, and the mounting part, filter cotton and receiving part of the breathing filter in the storage barrel fall to the corresponding blanking port, and at this time, the elastically stretched component blocks it from falling, and when the breathing filters at the blanking port are assembled in sequence and rotated to the bottom of the lower pressing block, the intermittent driving mechanism drives the reciprocating mechanism to move, so that the lower pressing block moves up and down reciprocatingly, and finally the assembled breathing filter falls.

[0005] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: although the existing device achieves the effect of assembling a respiratory filter, the existing device can only assemble one respiratory filter in one round of the assembly process, resulting in low assembly efficiency.

[0037] The top surface of the substrate 1 is fixedly connected with a motor 5 , the output shaft of the motor 5 is fixedly connected with a driving gear 501 , the driving gear 501 is meshed and engaged with the ring gear 306 , and the motor 5 is electrically connected to a PLC circuit controller 502 .

[0038] The four electric telescopic rods 401 are respectively fixedly connected to the top surfaces of the four connecting plates 302, and the output end of the electric telescopic rod 401 is fixedly connected with a semicircular ring 402, and a slide groove 403 is provided at the bottom of the semicircular ring 402. The discharging mechanism 4 includes a guide block 404, and the four guide blocks 404 are all fixedly connected to the top surface of the bottom ring 301. The four electric telescopic rods 401 are all electrically connected to the PLC circuit controller 502.

[0039] One end of the guide block 404 is slidably connected to the slide groove 403, and the end of the guide block 404 away from the electric telescopic rod 401 is fixedly connected to the torsion shaft 405, both ends of the torsion shaft 405 are rotatable, the torsion shaft 405 is fixedly connected to the baffle 406, and the end of the baffle 406 close to the guide block 404 is fixedly connected to the limiting block 407.

[0042] The center lines formed by the semicircular rings 402 and the baffles 406 of the four discharging mechanisms 4 are respectively located on the same line as the axis lines of the four circular grooves 305 .

[0043] The four positions where the fan-shaped grooves 101 are opened are all placed with fan-shaped collecting boxes 7 that match them, and the openings of the four semicircular rings 402 face the four fan-shaped collecting boxes 7 respectively.

[0044] First, the installation part, filter cotton and receiving part of the respiratory filter are placed in the four groups of storage barrels 603 respectively, and the motor 5 is started to drive the driving gear 501 to rotate, and the driving gear 501 drives the annular gear 306 to rotate, and the bottom ring 301 drives the top ring 304 to rotate. The top ring 304 and the bottom ring 301 are fixedly connected with the connecting column 303, and the annular turntable 103 enables the rotating mechanism 3 to rotate as a whole, so the driving gear 501 rotates with the rotating mechanism 3 as a whole, and the four discharging mechanisms 4 are respectively fixed on the inner side of the bottom ring 301, so when the bottom ring 301 rotates, the discharging mechanism 4 rotates accordingly, The LC circuit controller 502 accurately controls the rotating mechanism 3 to rotate ninety degrees as a whole. When the top ring 304 rotates, the four circular grooves 305 will pass through the four groups of storage barrels 603 in sequence. The mounting part, filter cotton and receiving part placed in each group of storage barrels 603 will fall into the annular space formed by the semicircular ring 402 and the baffle 406 through the circular grooves 305 in sequence. When the motor 5 drives the rotating mechanism 3 to rotate ninety degrees and then stops, the PLC circuit controller 502 controls the cylinder 201 to start, the output end of the cylinder 201 retracts, drives the L-shaped connecting rod 202 to move downward, and the L-shaped connecting rod 202 drives the extrusion block 2 03 passes through the circular groove 305 and is squeezed toward the respiratory filter accessory. After the extrusion is completed, the output end of the cylinder 201 extends again and drives the extrusion block 203 to rise. At this time, the four respiratory filters located in the four discharging mechanisms 4 are assembled. The PLC circuit controller 502 controls the four electric telescopic rods 401 to extend and squeeze the semicircular ring 402. The semicircular ring 402 slides on the guide block 404 through the slide groove 403. The semicircular ring 402 will push the respiratory filter to squeeze the baffle 406. After the baffle 406 is squeezed, the torsion shaft 405 rotates until the electric telescopic rod 401 is fully extended. The semicircular ring 402 pushes the respiratory filter to the edge of the bottom ring 301, and the respiratory filter falls into the fan-shaped collection box 7 under the action of gravity. Then, the torque of the torque shaft 405 causes the baffle 406 to rotate back to its original position. The limiting block 407 is used to resist the guide block 404 and the baffle 406 so that the baffle 406 is in a vertical state based on the guide block 404. The above operation is repeated to assemble the respiratory filter. This process is controlled by the PLC circuit controller 502. The present application can assemble four respiratory filters at one time. Compared with the existing device, the present application has the advantage of high assembly efficiency.

[0045] Principle of the present invention:

[0046] In the first step, the mounting part, filter cotton and receiving part of the respiratory filter are placed in four groups of storage barrels 603 respectively, and the motor 5 is started to drive the driving gear 501 to rotate, and the driving gear 501 drives the annular gear 306 to rotate, and the bottom ring 301 drives the top ring 304 to rotate. The top ring 304 and the bottom ring 301 are fixedly connected with the connecting column 303, and the annular turntable 103 enables the rotating mechanism 3 to rotate as a whole, so the driving gear 501 rotates with the rotating mechanism 3 as a whole, and the four discharging mechanisms 4 are respectively fixed on the inner side of the bottom ring 301, so when the bottom ring 301 rotates, the discharging mechanism 4 rotates accordingly, and the PLC circuit controller 502 accurately controls the rotating mechanism 3 to rotate ninety degrees as a whole.

[0047] In the second step, when the top ring 304 rotates, the four circular grooves 305 will pass through the four groups of storage barrels 603 in turn, and the mounting part, filter cotton and receiving part placed in each group of storage barrels 603 will fall into the annular space formed by the semicircular ring 402 and the baffle 406 through the circular grooves 305 in turn. When the motor 5 drives the rotating mechanism 3 to rotate ninety degrees and then stops, the PLC circuit controller 502 controls the cylinder 201 to start, and the output end of the cylinder 201 retracts, driving the L-shaped connecting rod 202 to move downward. The L-shaped connecting rod 202 drives the extrusion block 203 to pass through the circular grooves 305 and extrude toward the respiratory filter accessories. After the extrusion is completed, the output end of the cylinder 201 extends again and drives the extrusion block 203 to rise. At this time, the four respiratory filters located in the four discharging mechanisms 4 are assembled.

[0048] In the third step, the PLC circuit controller 502 controls the four electric telescopic rods 401 to extend and squeeze the semicircular ring 402. The semicircular ring 402 slides on the guide block 404 through the slide groove 403. The semicircular ring 402 will push the respiratory filter to squeeze the baffle 406. After the baffle 406 is squeezed, the torsion shaft 405 rotates until the electric telescopic rod 401 is fully extended and the semicircular ring 402 pushes the respiratory filter to the edge of the bottom ring 301. Under the action of gravity, the respiratory filter falls into the fan-shaped collection box 7, and then the torque of the torsion shaft 405 makes the baffle 406 return to its original position. The limiting block 407 is used to resist the guide block 404 and the baffle 406 so that the baffle 406 is in a vertical state based on the guide block 404. Repeat the above operations to assemble the respiratory filter. This process is controlled by the PLC circuit controller 502.

[0049] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
