Description

Technical Field

[0001] This invention relates to medical devices, and more particularly to a clamping assembly and a medical device production line. Background Technology

[0002] To improve production efficiency, an increasing number of medical devices are being manufactured using automation. In the automated production of medical devices, limitations such as space and cost often necessitate the use of multiple circulation lines to transfer materials. The materials between different circulation lines require material transfer devices. A circulation line includes clamping components and a circulation drive. The clamping components hold the materials, and the circulation drive drives the clamping components to move cyclically. When materials are transferred between different circulation lines, the clamping components of the preceding circulation line must first release the material before it can move under the influence of the clamping components of the following circulation line. Conversely, the clamping components of the following circulation line must first open before they can clamp the material. Therefore, the efficiency of the clamping components in releasing and clamping materials is relatively low and needs improvement. Summary of the Invention

[0003] Therefore, it is necessary to provide an improved clamping assembly and a medical device production line. This clamping assembly can respond promptly to material movement needs, thereby improving the efficiency of material release and clamping. Medical device production lines using this clamping assembly achieve higher production efficiency.

[0004] The present invention first provides a clamping assembly, including a first clamping part and a second clamping part, one end of the first clamping part and one end of the second clamping part are connected, and the other end of the first clamping part and the other end of the second clamping part are spaced apart. The first clamping part and the second clamping part clamp materials, and the first clamping part and the second clamping part can elastically maintain the relative position of the first clamping part and the second clamping part.

[0005] By adopting the above technical solution, the existing clamping assembly requires pneumatic control of both the first and second clamping parts when clamping and releasing materials, thus failing to respond promptly to material movement demands. However, the first and second clamping parts can elastically maintain their relative positions. Therefore, when clamping and releasing materials, as long as the material can overcome the elasticity between the first and second clamping parts, allowing their relative positions to change, the material can enter and leave between them. After the material enters and leaves between the first and second clamping parts, the first and second clamping parts can elastically maintain their relative positions as close as possible to their state before entering and leaving the material, thus completing the clamping and releasing process. Therefore, the clamping and releasing of materials can respond promptly to material movement demands, thereby improving the efficiency of both clamping and releasing materials.

[0006] In one embodiment of the present invention, the second clamping part includes a limiting section and a clamping section. The two ends of the clamping section are respectively connected to the connection point of the first clamping part and the second clamping part and the limiting section. The minimum distance between the limiting section and the first clamping part is less than the distance between the clamping section and the first clamping part.

[0007] By adopting the above technical solution, when the material is clamped between the clamping section and the first clamping part, the material will be blocked by the limiting part when leaving the first clamping part and the second clamping part, thereby increasing the difficulty of the material leaving the clamping assembly and preventing the material from easily leaving the clamping assembly.

[0008] In one embodiment of the present invention, the end of the limiting segment away from the clamping segment is provided with a guiding surface for guiding material into the space between the first clamping portion and the second clamping portion.

[0009] By adopting the above technical solution, the setting of the limiting part increases the difficulty of material detaching from the clamping assembly, and also increases the difficulty of material entering the space between the first clamping part and the second clamping part. The setting of the guiding surface serves to guide the material into the space between the first clamping part and the second clamping part.

[0010] In one embodiment of the present invention, the clamping assembly further includes a main body portion, which is connected to the first clamping portion, and the main body portion and the second clamping portion are spaced apart.

[0011] By adopting the above technical solution, the main body surrounds the first clamping part and the second clamping part, thereby protecting the first and second clamping parts and preventing them from undergoing excessive elastic deformation due to interference, which would affect the performance of the first and second clamping parts in maintaining their relative positions. Compared to a method where the main body is connected to both the first and second clamping parts simultaneously, the main body is connected to the first clamping part but spaced apart from the second clamping part, thus reducing the resistance to elastic deformation of the first and second clamping parts.

[0012] In one embodiment of the present invention, the clamping assembly further includes a limiting part, one end of which is connected to the first clamping part, and the other end of which is spaced apart from the clamping segment. A first positioning space and a second positioning space are formed between the clamping segment and the first clamping part, and the limiting part is located between the first positioning space and the second positioning space.

[0013] By adopting the above technical solution, assuming that the first positioning space is closer to the limiting section than the second positioning space, the material is usually clamped in the first positioning space, while the second positioning space is in an empty state. However, during the process of clamping and releasing the material, the second positioning space changes as the clamping section moves relative to the first clamping part, thereby reducing the resistance to elastic deformation of the first and second clamping parts.

[0014] In one embodiment of the present invention, the limiting part is smoothly connected to the first clamping part on the side facing the first positioning space, and / or the limiting part is smoothly connected to the first clamping part on the side facing the second positioning space.

[0015] In one embodiment of the present invention, the clamping assembly further includes a connecting portion, the two ends of which are respectively connected to one end of the first clamping portion and one end of the second clamping portion, and the main body portion surrounds the connecting portion and the main body portion and the connecting portion are spaced apart.

[0016] By adopting the above technical solution, the main body surrounds the connecting part, thereby protecting the connecting part and preventing it from undergoing excessive elastic deformation due to interference, which would affect the performance of the connecting part in maintaining the relative position of the first clamping part and the second clamping part. Compared to a method where the main body and the connecting part are connected together, the main body and the connecting part are spaced apart, thereby reducing the resistance to elastic deformation of the first clamping part and the second clamping part.

[0017] In one embodiment of the present invention, the main body surrounds the first clamping portion and the second clamping portion.

[0018] The present invention also provides a medical device production line, including the above-described clamping assembly.

[0019] By adopting the above technical solution, the medical device production line using this clamping component has a high production efficiency.

[0020] In one embodiment of the present invention, the medical device production line further includes a waste rejection drive and a waste rejection component. The waste rejection drive drives the waste rejection component to move to act on the material. Under the action of the waste rejection component, the material overcomes the resistance of the clamping assembly and disengages from the clamping assembly.

[0021] By adopting the above technical solution, the way the clamping component clamps the material is changed. Therefore, when rejecting waste, only the rejecting component needs to act on the material so that the material can overcome the resistance of the clamping component, thereby speeding up the rejecting efficiency.

[0022] In one embodiment of the present invention, the waste removal component moves under the action of the waste removal drive component to enter between the first clamping part and the second clamping part.

[0023] By adopting the above technical solution, the material is clamped between the first clamping part and the second clamping part. Therefore, when the rejecting part moves between the first clamping part and the second clamping part, it can be ensured that the material is removed from the first clamping part and the second clamping part, that is, that the material is removed from the clamping assembly.

[0024] In one embodiment of the present invention, the medical device production line further includes a detection component that detects whether there is material between the first clamping part and the second clamping part. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Embodiments of the present invention first provide, as follows Figure 1 The clamping assembly shown includes a first clamping part 100, a second clamping part 200, a connecting part 300, a main body part 400, and a limiting part 500.

[0032] Reference Figure 1 One end of the first clamping part 100 and one end of the second clamping part 200 are respectively connected to both ends of the connecting part 300. The other ends of the first clamping part 100 and the second clamping part 200, which are away from the connecting part 300, are spaced apart. The first clamping part 100 and the second clamping part 200 clamp the material. The first clamping part 100 and the second clamping part 200 can elastically maintain their relative positions. The main body part 400 surrounds the first clamping part 100, the connecting part 300, and the second clamping part 200. The main body part 400 is connected to the first clamping part 100, and the main body part 400 and the second clamping part 200 are spaced apart. The main body part 400 and the connecting part 300 are also spaced apart. Figure 1In the specific embodiment shown, the first clamping portion 100 is entirely connected to the main body portion 400. The main body portion 400 surrounds the first clamping portion 100 and the second clamping portion 200, thereby protecting the first clamping portion 100 and the second clamping portion 200 and preventing them from undergoing excessive elastic deformation due to interference, which would affect the performance of the first clamping portion 100 and the second clamping portion 200 in maintaining their relative position elastically. Compared to a configuration where the main body portion 400 is simultaneously connected to both the first clamping portion 100 and the second clamping portion 200, the main body portion 400 is connected to the first clamping portion 100 but spaced apart from the second clamping portion 200, thereby reducing the resistance to elastic deformation of the first clamping portion 100 and the second clamping portion 200. The main body 400 surrounds the connecting part 300, thereby protecting the connecting part 300 and preventing it from undergoing excessive elastic deformation due to interference, which would affect the performance of the connecting part 300 in maintaining the relative position of the first clamping part 100 and the second clamping part 200. Compared to a connection between the main body 400 and the connecting part 300, the main body 400 and the connecting part 300 are spaced apart, thereby reducing the resistance to elastic deformation of the first clamping part 100 and the second clamping part 200.

[0033] Reference Figure 1 The first clamping part 100, the second clamping part 200, the connecting part 300, and the limiting part 500 correspond one-to-one, and the number of the first connecting part 300, the second clamping part 200, the connecting part 300, and the limiting part 500 is adapted to the main body part 400. Figure 1 In the specific embodiment shown, there are 12 first clamping parts 100, 12 second clamping parts 200, 12 connecting parts 300, and 12 limiting parts 500. The 12 first clamping parts 100, 12 second clamping parts 200, 12 connecting parts 300, and 12 limiting parts 500 are arranged in two rows. The main body 400 is connected to and surrounds the two rows of first clamping parts 100, connecting parts 300, and second clamping parts 200. The main body 400 is spaced apart from the two rows of second clamping parts 200, and the main body 400 is also spaced apart from the two rows of connecting parts 300.

[0034] Reference Figure 1The second clamping part 200 includes a limiting section 210 and a clamping section 220. The two ends of the clamping section 220 are respectively connected to the connecting part 300 and the limiting section 210. The minimum distance between the limiting section 210 and the first clamping part 100 is less than the distance between the clamping section 220 and the first clamping part 100. A guide surface 211 is provided at the end of the limiting section 210 away from the clamping section 220 to guide material into the space between the clamping section 220 and the first clamping part 100. When material is clamped between the clamping section 220 and the first clamping part 100, the material will be blocked by the limiting part 500 when leaving the space between the first clamping part 100 and the second clamping part 200, thereby increasing the difficulty for the material to detach from the clamping assembly and preventing the material from easily detaching from the clamping assembly. The setting of the limiting part 500 increases the difficulty for the material to detach from the clamping assembly and also increases the difficulty for the material to enter the space between the first clamping part 100 and the second clamping part 200. The guide surface 211 is designed to guide the material into the space between the first clamping part 100 and the second clamping part 200.

[0035] Reference Figure 1 One end of the limiting part 500 is connected to the first clamping part 100, and the other end of the limiting part 500 is spaced apart from the clamping section 220. A first positioning space 610 and a second positioning space 620 are formed between the clamping section 220 and the first clamping part 100. The limiting part 500 is located between the first positioning space 610 and the second positioning space 620. Since the other end of the limiting part 500 is spaced apart from the clamping section 220, the first positioning space 610 and the second positioning space 620 are in a connected state. The side of the limiting part 500 facing the first positioning space 610 is smoothly connected to the first clamping part 100, and the side of the limiting part 500 facing the second positioning space 620 is also smoothly connected to the first clamping part 100. Assuming that the first positioning space 610 is closer to the limiting section 210 than the second positioning space 620, the material is usually clamped in the first positioning space 610, and the second positioning space 620 is in an empty state. However, during the process of clamping and releasing the material, the second positioning space 620 changes as the clamping section 220 moves relative to the first clamping part 100, thereby reducing the resistance to elastic deformation of the first clamping part 100 and the second clamping part 200.

[0036] In existing clamping assemblies, both the first clamping part 100 and the second clamping part 200 require pneumatic control for clamping and releasing materials. Therefore, when materials need to be transferred between different circulation lines, the clamping assembly of the next circulation line clamps the material before the clamping assembly of the previous circulation line has released it. Subsequently, the clamping assembly of the previous circulation line releases the material, allowing the clamping assembly of the next circulation line to move the material. This results in an inability to respond promptly to material movement demands, leading to low efficiency in both clamping and releasing materials. However, the first clamping part 100 and the second clamping part 200 can elastically maintain their relative positions. Therefore, when clamping and releasing materials are required, as long as the material can overcome the elasticity between the first clamping part 100 and the second clamping part 200, causing their relative positions to change, the material can enter and leave between them. After the material enters and leaves between the first clamping part 100 and the second clamping part 200, the first clamping part 100 and the second clamping part 200 can elastically maintain their relative positions as close as possible to the state they were in before the material entered and left between them, thus completing the clamping and releasing of the material. Therefore, the clamping and releasing of the material can respond promptly to the material's movement needs, thereby improving the efficiency of both clamping and releasing the material.

[0037] It is understood that the first clamping part 100 may also include a limiting segment 210 and a clamping segment 220. The two ends of the clamping segment 220 of the first clamping part 100 are respectively connected to the connecting part 300 and the limiting segment 210 of the first clamping part 100. In this case, the limiting segment 210 of the first clamping part 100 and the limiting segment 210 of the second clamping part 200 may be close to each other, or only the limiting segment 210 of the first clamping part 100 may be close to the limiting segment 210 of the second clamping part 200, or only the limiting segment 210 of the second clamping part 200 may be close to the limiting segment 210 of the first clamping part 100, as long as the minimum distance between the limiting segment 210 of the first clamping part 100 and the second clamping part 200 is less than the distance between the clamping segment 220 of the first clamping part 100 and the clamping segment 220 of the second clamping part 200. The limiting section 210 of the first clamping part 100, which is away from the clamping section 220 of the first clamping part 100, is also provided with a guiding surface 211 for guiding material into the space between the clamping section 220 of the first clamping part 100 and the second clamping part 200.

[0038] Understandably, the side of the limiting part 500 facing the first positioning space 610 and the first clamping part 100 are no longer smoothly connected.

[0039] Understandably, the side of the limiting part 500 facing the second positioning space 620 and the first clamping part 100 are no longer smoothly connected.

[0040] Embodiments of the present invention further provide, as follows: Figure 2 A medical device production line is shown, including a rejection drive 700, a rejection component 800, a detection component 900, and a clamping assembly as described in the above embodiment. The rejection component 800 moves under the drive of the rejection drive 700 to the space between the first clamping part 100 and the second clamping part 200, thus acting on the material. Under the action of the rejection component 800, the material overcomes the resistance of the clamping assembly and detaches from it, falling into the waste channel 1000 under its own gravity. After being guided through the waste channel 1000, the material enters the waste box 2000. The material is clamped between the first clamping part 100 and the second clamping part 200; therefore, when the rejection component 800 moves between the first clamping part 100 and the second clamping part 200, it ensures that the material detaches from this space, i.e., it ensures that the material detaches from the clamping assembly. The way the clamping assembly holds the material has been changed, so during rejection, only the rejection component 800 needs to act on the material to allow it to overcome the resistance of the clamping assembly, thus speeding up the rejection process. The detection component 900 detects whether there is material between the first clamping part 100 and the second clamping part 200, thereby determining whether there is any material residue after rejection. Medical device production lines using this clamping assembly have high production efficiency.

[0041] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0042] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
