Description

Technical Field

[0001] The present invention relates to medical devices, and in particular to a transfer device and a medical device production line. Background Art

[0002] With the development of technology, the degree of automation of medical device production lines is getting higher and higher. In medical device production lines, the transfer device plays the role of transporting materials to various workstations for processing. In order to save space, the transfer device usually includes a rotating drive member, a rotating shaft, a turntable and a clamping assembly. The rotating drive member drives the turntable to rotate through the rotating shaft, driving the clamping assembly connected to the turntable to rotate, thereby transferring the material clamped by the clamping assembly to each workstation. When the mobile device transfers the material to the cleaning station for cleaning by the cleaning device, the cleaning device usually uses a cleaning fluid for cleaning. The contact of the cleaning fluid with the transfer device, especially the contact with the rotating shaft, will cause the rotating shaft to rust and shorten the service life of the rotating shaft. Therefore, how to achieve effective protection of the transfer device, especially to avoid contact between the cleaning fluid and the rotating shaft, is a problem that people urgently need to solve. Summary of the Invention

[0003] In view of this, it is necessary to provide an improved transfer device and a medical device production line, wherein the transfer device can achieve effective protection to prevent the cleaning fluid from contacting the rotating shaft. The medical device production line using the transfer device has a stable and reliable effect.

[0004] The present invention first provides a transfer device, including a mounting platform, a turntable, a rotating shaft, a rotating drive member and a clamping assembly, wherein the clamping assembly is connected to the turntable and distributed circumferentially along the turntable, the clamping assembly is used to clamp the material, the rotating shaft connects the turntable and the rotating drive member, and the rotating drive member drives the turntable to rotate through the rotating shaft to drive the material to rotate to a cleaning device distributed on the mounting platform for cleaning, and the transfer device also includes an inner protective member, at least part of the inner protective member is located between the turntable and the mounting platform, and at least part of the inner protective member isolates the cleaning device and the rotating shaft.

[0005] By adopting the above technical solution, the inner protective part isolates the cleaning device and the rotating shaft, thereby reducing the contact between the cleaning liquid used by the cleaning device during the cleaning process and the rotating shaft, thereby reducing the rust of the rotating shaft, extending the service life of the rotating shaft, and achieving effective protection.

[0006] In one embodiment of the present invention, the inner protective member forms an inner isolation chamber that wraps the rotating shaft, and the cleaning device is isolated from the inner isolation chamber.

[0007] By adopting the above technical solution, the inner protective member forms an inner isolation cavity, and the rotating shaft can be isolated by the inner protective member and the cleaning device, thereby greatly reducing the contact between the cleaning liquid and the rotating shaft, thereby reducing the rust of the rotating shaft and extending the service life of the rotating shaft.

[0008] In one embodiment of the present invention, the transfer device further includes an outer protective member, the outer protective member and the inner protective member form an outer isolation cavity, the cleaning device is located in the outer isolation cavity, and the outer isolation cavity surrounds the inner isolation cavity.

[0009] By adopting the above technical solution, the outer protective part and the inner protective part work together to ensure that the cleaning liquid used by the cleaning device during the cleaning process is in the outer isolation chamber as much as possible, thereby preventing the cleaning liquid from entering the inner isolation chamber and contacting the rotating shaft to cause rust of the rotating shaft, and preventing the cleaning liquid from flowing into the outside and polluting the entire production space.

[0010] In one embodiment of the present invention, the transfer device further comprises a plurality of partition plates, and the plurality of partition plates divide the outer isolation chamber into a cleaning space, and the cleaning device is located in the cleaning space.

[0011] By adopting the above technical solution, the cleaning device is isolated in the cleaning space by using a partition plate, so that the cleaning liquid used by the cleaning device during the cleaning process is located only in the cleaning space as much as possible, thereby reducing the diffusion of the cleaning liquid in the entire outer isolation cavity.

[0012] In one embodiment of the present invention, the transfer device also includes an air pump and an exhaust channel connected to each other, the exhaust channel is connected to the inner isolation chamber and / or the outer isolation chamber, and the air pump extracts the gas in the inner isolation chamber and / or the outer isolation chamber through the exhaust channel.

[0013] By adopting the above technical solution, when cleaning liquid remains in the inner or outer isolation chamber, it may exist in liquid form or evaporate to generate water vapor. The air pump and the air extraction channel remove the remaining water vapor in the inner or outer isolation chamber, which also promotes further volatilization of the cleaning liquid, ultimately achieving the removal of the cleaning liquid. This prevents the cleaning liquid or water vapor from contacting the rotating shaft, causing corrosion of the rotating shaft, and also prevents the cleaning liquid from flowing into the outside world and contaminating the entire production space.

[0014] In one embodiment of the present invention, the inner protective member forms an inner isolation chamber that surrounds the cleaning device, and the rotating shaft is isolated from the inner isolation chamber.

[0015] In one embodiment of the present invention, the transfer device further includes an outer protective member, the outer protective member and the inner protective member form an outer isolation cavity, the rotating shaft is located in the outer isolation cavity, and the outer isolation cavity surrounds the inner isolation cavity.

[0016] In one embodiment of the present invention, the transfer device also includes an air pump and an exhaust channel connected to each other, the exhaust channel is connected to the inner isolation chamber and / or the outer isolation chamber, and the air pump extracts the gas in the inner isolation chamber and / or the outer isolation chamber through the exhaust channel.

[0017] In one embodiment of the present invention, the inner protective member includes a first protective member and a second protective member that are separately provided, the first protective member is connected to the turntable and rotates with the turntable, and the second protective member is connected to the mounting platform.

[0018] By adopting the above technical solution, if the first protective member and the second protective member are provided as a whole, it means that the inner protective member as a whole is either connected to the mounting platform or to the turntable. If the inner protective member is connected to the mounting platform as a whole, the inner protective member cannot rotate with the turntable, which means that there will be a large gap between the inner protective member and the turntable. The material is clamped by the clamping assembly and approaches the turntable, so there is a large gap between the inner protective member and the turntable, which will increase the probability of the cleaning liquid entering the inner isolation chamber. If the inner protective member is connected to the turntable as a whole, the inner protective member needs to rotate with the turntable, which means that there is a large gap between the inner protective member as a whole and the mounting platform. Cleaning liquid is easy to accumulate on the mounting platform, so a large gap between the inner protective member and the mounting platform will increase the probability of the cleaning liquid entering the inner isolation chamber. Therefore, the first protective member and the second protective member are provided separately, which can reduce the probability of the cleaning liquid entering the inner isolation chamber.

[0019] In one embodiment of the present invention, the transfer device also includes a cover, a lifting shaft and a lifting drive member. The cover is located above the turntable and covers the turntable. One end of the lifting shaft acts on the cover, and the other end of the lifting shaft passes through the turntable, the rotating shaft and the rotating drive member in sequence and is connected to the lifting drive member. The lifting drive member drives the lifting shaft to drive the cover to move axially relative to the turntable.

[0020] By adopting this technical solution, the cover protects the turntable, preventing other objects from coming into contact with it. When maintenance is required, the lifting drive, via the lifting shaft, drives the cover axially relative to the turntable, until the cover loses its coverage. The lifting shaft, which runs through the rotating shaft, prevents the shaft from interfering with the rotation of the turntable and the rotating shaft, while still enabling the cover to move axially.

[0021] In one embodiment of the present invention, the transfer device further includes a guide support member, and the guide support member is located between the turntable and the lifting shaft.

[0022] By adopting the above technical solution, the setting of the guide support member plays the role of guiding the movement of the lifting shaft and supporting the lifting shaft.

[0023] In one embodiment of the present invention, the guide support member extends from one end close to the turntable to be connected to the rotation driving member.

[0024] The present invention further provides a medical device production line, comprising the above-mentioned transfer device and cleaning device, wherein the cleaning device cleans the material with a cleaning liquid.

[0025] By adopting the above technical solution, the medical device production line using the transfer device has a stable and reliable effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The embodiment of the present invention first provides Figure 1 The transfer device shown includes a mounting platform 100 , a rotating assembly 200 , a clamping assembly 300 , a waterproof assembly 400 , a lifting assembly 500 and an exhaust assembly 600 .

[0034] Reference Figure 1 , the mounting platform 100 is provided with a rotating hole that passes through the mounting platform 100. The rotating assembly 200 includes a turntable 210, a rotating shaft 220 and a rotating driving member 230. The turntable 210 and the rotating driving member 230 are respectively located above and below the mounting platform 100. One end of the rotating shaft 220 is connected to the center of the turntable 210, and the other end passes through the rotating hole and is connected to the rotating driving member 230. The rotating driving member 230 drives the turntable 210 to rotate through the rotating shaft 220. Figure 1 In the embodiment shown, the rotary driving member 230 is a divider.

[0035] Reference Figure 1 and Figure 2 , there are multiple clamping assemblies 300, and the multiple clamping assemblies 300 are connected to the turntable 210 and evenly distributed along the circumference of the turntable 210. Each clamping assembly 300 includes a clamping jaw 310 and a clamping drive 320. The clamping jaw 310 includes a clamping portion 311 and a drive portion 312 connected to each other. The clamping portion 311 is used to clamp the material, and the drive portion 312 drives the clamping portion 311 to pick up and place the material under the action of the clamping drive 320. Figure 1In the illustrated embodiment, the clamping drive 320 is a pneumatic cylinder. The rotary drive 230 drives the turntable 210 to rotate, driving the material to the cleaning device 700, drying device 800, and siliconizing device 900, which are distributed on the mounting platform 100. The cleaning device 700 cleans the material with a cleaning fluid, the drying device 800 dries the cleaned material, and the siliconizing device 900 sprays silicone oil on the dried material for siliconization. The cleaning fluid can be water or an injection solution.

[0036] Reference Figure 1 and Figure 2The waterproof assembly 400 includes an inner protective member 410, an outer protective member 420, and a cover 430. The mounting platform 100 and the inner protective member 410 enclose an inner isolation chamber 440. The rotating shaft 220 is located inside the inner isolation chamber 440, while the cleaning device 700, the drying device 800, and the siliconization device 900 are all located outside the inner isolation chamber 440. Therefore, the inner protective member 410 simultaneously serves to isolate the rotating shaft 220 from the cleaning device 700, the rotating shaft 220 from the drying device 800, and the rotating shaft 220 from the siliconization device 900. In addition to the cleaning device 700, the drying device 800 will also come into contact with the cleaning fluid during the drying process, and the siliconization device 900 may also have residual cleaning fluid. The inner protective member 410 isolates the cleaning device 700, the drying device 800, and the siliconizing device 900 from the rotating shaft 220, thereby greatly reducing the contact between the cleaning liquid and the rotating shaft 220, thereby reducing the corrosion of the rotating shaft 220, extending the service life of the rotating shaft 220, and achieving effective protection. The inner protective member 410 includes a first protective member 411, a second protective member 412, and a third protective member 413 that are separately arranged. The first protective member 411 and the second protective member 412 are both located between the turntable 210 and the mounting platform 100. The first protective member 411 is connected to the turntable 210, and the second protective member 412 is connected to the mounting platform 100. The first protective member 411 is radially located on the inner side of the turntable 210, and the third protective member 413 is radially located on the outer side of the turntable 210. At the same time, one end of the third guard 413 extends downward to below the turntable 210, and the other end extends upward to above the turntable 210 and connects to the outer guard 420. The third guard 413 is spaced downward from the clamping jaw 310 but positioned as close to the clamping jaw 310 as possible to minimize the gap between the third guard 413 and the clamping jaw 310. The third guard 413 is spaced radially from the turntable 210 but positioned as close to the turntable 210 as possible to minimize the gap between the third guard 413 and the turntable 210. Therefore, the first guard 411 rotates relative to the second guard 412 and the third guard 413 following the turntable 210. A passage connecting the interior and exterior of the inner isolation chamber 440 is formed between the first and second protective members 411, 412. The first and second protective members 411, 412 overlap in height, and the first protective member 411 is located radially outward of the second protective member 412. This makes it more difficult for the cleaning fluid to pass through the inner protection member 410 and enter the inner isolation chamber 440, thereby enhancing the waterproof performance of the inner protection member 410. If the first and second protective members 411, 412 are integrally provided, the inner protection member 410 as a whole is connected to either the mounting platform 100 or the turntable 210. If the inner protection member 410 is entirely connected to the mounting platform 100, the inner protection member 410 cannot rotate with the turntable 210, which means that a large gap will exist between the inner protection member 410 and the turntable 210.The material is clamped by the clamping assembly 300 and brought closer to the turntable 210. Therefore, a large gap exists between the inner guard 410 and the turntable 210, increasing the probability of cleaning fluid entering the inner isolation chamber 440. If the inner guard 410 were entirely connected to the turntable 210, it would need to rotate with the turntable 210, meaning a large gap exists between the inner guard 410 and the mounting platform 100. Cleaning fluid tends to accumulate on the mounting platform 100, so a large gap between the inner guard 410 and the mounting platform 100 increases the probability of cleaning fluid entering the inner isolation chamber 440. Therefore, the first guard 411 and the second guard 412 are separate components to reduce the probability of cleaning fluid entering the inner isolation chamber 440. The first guard 411 is provided with a clearance hole, through which the drive unit 312 passes to close the clearance hole. The clamping jaws 310 are located outside the inner isolation chamber 440, while the clamping drive 320 is located inside. An outer isolation chamber 450 is formed between the outer protective member 420 and the inner protective member 410, and the outer isolation chamber 450 surrounds the inner isolation chamber 440. The cleaning device 700, the drying device 800, and the siliconization device 900 are all located in the outer isolation chamber 450. The outer protective member 420 and the inner protective member 410 work together to ensure that the cleaning liquid used by the cleaning device 700 during the cleaning process and the cleaning liquid contacted by the drying device 800 during the drying process are as much as possible in the outer isolation chamber 450, thereby preventing the cleaning liquid from entering the inner isolation chamber 440 and contacting the rotating shaft 220, causing corrosion of the rotating shaft 220, and preventing the cleaning liquid from flowing into the outside and contaminating the entire production space. In some embodiments, the drying device 800 and the siliconization device 900 can also be placed outside the outer protective member 420. The cover 430 is located above the turntable 210 and covers the turntable 210. The cover 430 radially abuts the inner wall of the third protective member 413. The cover 430 protects the turntable 210, preventing other objects from coming into contact with it. When maintenance is required, the lift drive 520, via the lift shaft 510, drives the cover 430 axially relative to the turntable 210 until it no longer covers the turntable 210. The lift shaft 510 extends through the rotating shaft 220, preventing the lift shaft 510 from interfering with the rotation of the turntable 210 and the rotating shaft 220 while also enabling the cover 430 to move axially.

[0037] In some embodiments, reference Figure 3The cover 430 and the outer protective member 420 are integrally formed. In this case, the third protective member 413 can be omitted, and the first protective member 411 can be positioned radially outward from the turntable 210. One end of the first protective member 411 extends downward below the turntable 210, and the other end extends upward above the turntable 210. The second protective member 412 extends upward from the mounting platform 100 to a position spaced apart from the turntable 210 but as close to the turntable 210 as possible to minimize the gap between the second protective member 412 and the turntable 210.

[0038] Reference Figure 1 and Figure 2 The lifting assembly 500 includes a lifting shaft 510, a lifting drive 520, and a guide support 530. One end of the lifting shaft 510 acts on the cover 430, and the other end passes through the turntable 210, the rotating shaft 220, and the rotating drive 230 in sequence and is connected to the lifting drive 520. The lifting drive 520 drives the lifting shaft 510 to move axially relative to the turntable 210, thereby driving the cover 430 to move axially relative to the turntable 210, so that the cover 430 moves until it loses its cover on the turntable 210. Figure 1 In the illustrated embodiment, the lifting drive 520 is a pneumatic cylinder. A guide support 530 is located between the turntable 210 and the lifting shaft 510 and extends from one end near the turntable 210 to connect with the rotating drive 230. The guide support 530 serves to guide the movement of the lifting shaft 510 and to support the lifting shaft 510.

[0039] Reference Figure 1 The air extraction assembly 600 includes an air pump and an air extraction channel connected thereto. The air extraction channel passes through the cover 430 and enters the inner isolation chamber 440, thereby achieving communication between the air extraction channel and the inner isolation chamber 440. In some embodiments, referring to Figure 3 , the exhaust channel passes through the outer protective part 420 and enters the outer isolation chamber 450, thereby realizing the connection between the exhaust channel and the outer isolation chamber 450. Regardless of whether the exhaust channel is connected to the inner isolation chamber 440 or the outer isolation chamber 450, since the inner isolation chamber 440 and the outer isolation chamber 450 are still in a connected state, the gas in the inner isolation chamber 440 and the outer isolation chamber 450 can be extracted during the operation of the exhaust component. It should be noted that when the cleaning liquid exists in the form of droplets, the droplets can also be extracted by the exhaust channel. When the cleaning liquid remains in the inner isolation chamber 440 or the outer isolation chamber 450, the cleaning liquid either exists in the form of liquid or evaporates to produce water vapor. The air pump and the exhaust channel are used to remove the water vapor remaining in the inner isolation chamber 440 or the outer isolation chamber 450, which will also promote the further volatilization of the cleaning liquid, and finally achieve the removal of the cleaning liquid, thereby avoiding the cleaning liquid or water vapor from contacting the rotating shaft 220 and causing rust on the rotating shaft 220, and also preventing the cleaning liquid from flowing into the outside and polluting the entire production space.

[0040] In some embodiments, the transfer device further comprises a plurality of partition plates. The plurality of partition plates divide the outer isolation chamber 450 into a cleaning space, a drying space and a siliconization space. The cleaning device 700 is located in the cleaning space, the drying device 800 is located in the drying space, and the siliconization device 900 is located in the siliconization space. A feed trough is provided on the side of each partition plate close to the inner isolation cover, and the feed trough can connect the cleaning space and the drying space as well as the drying space and the siliconization space. Therefore, the material can pass through the cleaning space, the drying space and the siliconization space in sequence through the feed trough. The partition plates are used to isolate the cleaning device 700 in the cleaning space, and the drying device 800 in the drying space, so that the cleaning liquid used by the cleaning device 700 during the cleaning process is located only in the cleaning space as much as possible, and the cleaning liquid contacted by the drying device 800 during the drying process is only located in the drying space, thereby reducing the diffusion of the cleaning liquid in the entire outer isolation chamber 450.

[0041] In some embodiments, the cleaning device 700, the drying device 800, and the siliconizing device 900 are all located inside the inner isolation chamber 440, while the rotating shaft 220 is located outside the inner isolation chamber 440. In this case, the transfer device may also include multiple partitions, which divide the inner isolation chamber 440 into a cleaning space, a drying space, and a siliconizing space. Of course, if the drying device 800 or the siliconizing device 900 can be placed outside the outer protective member 420, the provision of the partitions can also be reduced. If both the drying device 800 and the siliconizing device 900 can be placed outside the outer protective member 420, the provision of the partitions can also be eliminated.

[0042] The present invention further provides Figure 2 The medical device production line shown includes the aforementioned transfer device, a cleaning device 700, a drying device 800, and a siliconizing device 900. The cleaning device 700, drying device 800, and siliconizing device 900 are all located on a mounting platform 100 and arranged around a turntable 210. A medical device production line employing this transfer device provides stable and reliable performance. This medical device production line can be specifically applied to the production of prefilled syringes.

[0043] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. Any appropriate changes and modifications to the above embodiments fall within the scope of the present invention as long as they are within the spirit of the present invention.
