Unless defined otherwise, 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 belongs. 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.
The embodiment of the invention firstly provides a medical apparatus production line shown in fig. 1, which comprises a first transferring device 100, a pin device 200, a heating device 300, a gluing device 400, a first curing device 500, a transplanting device 600, a second transferring device 700, a second curing device 800, a testing device 900 and a rejecting device 1000. The first transfer device 100 and the second transfer device 700 are located at opposite sides of the transplanting device 600. The transplanting device 600 is used to move material from the first transfer device 100 to the second transfer device 700.
Referring to fig. 1, 2 and 3, the first transfer device 100 includes a first driving member, a plurality of first clamping members 110 and a plurality of auxiliary clamping members 120. The plurality of first clamping members 110 rigidly clamp the material and the plurality of auxiliary clamping members 120 rigidly clamp the needle. The plurality of first clamping members 110 and the plurality of auxiliary clamping members 120 are circularly moved by the driving of the first driving member, thereby moving the material clamped by the plurality of first clamping members 110 and the needles clamped by the plurality of auxiliary clamping members 120. The material is sequentially moved to pass through the pin device 200, the heating device 300, the glue spreading device 400 and the first curing device 500 by the driving of the first driving member. Meanwhile, the moving direction of the material from the pin device 200 to the heating device 300 is opposite to the moving direction of the material from the heating device 300 to the glue spreading device 400 under the driving of the first driving member. The pin device 200 is used for assembling the pin and the material, the heating device 300 is used for heating the pin and the material assembling part, the glue spreading device 400 is used for coating glue on the pin and the material assembling part, and the first curing device 500 is used for curing the glue through an ultraviolet lamp. When the glue is applied to the needle and material assembling portion, the needle and material assembling portion is heated by the heating device 300, so that heat of the needle and material assembling portion is transferred to the glue, thereby accelerating curing time of the glue of the needle and material assembling portion, and further, subsequent processing can be performed as soon as possible, and production efficiency is improved. On the way the first transfer device 100 transfers material, the material turns as it passes through the heating device 300. In this way, when the heating device 300 heats the material, the space is relatively large, and the pin device 200 and the glue spreading device 400 are prevented from being heated while the material is heated.
Referring to fig. 2 and 4, the second transfer device 700 includes a second driving member and a plurality of second clamping members 710. Each of the second clamping members 710 includes a first clamping portion 711, a second clamping portion 712, a connecting portion 713, a main body portion 714, and a limiting portion 715.
Referring to fig. 4, one end of the first clamping part 711 and one end of the second clamping part 712 are connected to both ends of the connection part 713, respectively, and the other end of the first clamping part 711 remote from the connection part 713 and the other end of the second clamping part 712 remote from the connection part 713 are spaced apart. The first clamping portion 711 and the second clamping portion 712 clamp the material. The first clamping part 711 and the second clamping part 712 can elastically maintain the relative positions of the first clamping part 711 and the second clamping part 712, thereby realizing that the second clamping piece 710 elastically clamps the material. The body portion 714 surrounds the first clamping portion 711, the connecting portion 713, and the second clamping portion 712. The main body 714 is connected to the first clamping part 711, the main body 714 is spaced apart from the second clamping part 712, and the main body 714 is also spaced apart from the connecting part 713. In the embodiment shown in fig. 1, the first clamping portion 711 is entirely connected to the main body portion 714. The main body portion 714 surrounds the first clamping portion 711 and the second clamping portion 712, thereby protecting the first clamping portion 711 and the second clamping portion 712 from excessive elastic deformation caused by interference of the first clamping portion 711 and the second clamping portion 712, and thus affecting the performance of the first clamping portion 711 and the second clamping portion 712 in elastically maintaining the relative positions of the first clamping portion 711 and the second clamping portion 712. Compared to the manner in which the main body 714 is connected to both the first clamping portion 711 and the second clamping portion 712, the main body 714 is connected to the first clamping portion 711 and is spaced apart from the second clamping portion 712, thereby reducing the resistance to elastic deformation of the first clamping portion 711 and the second clamping portion 712. The main body portion 714 surrounds the connection portion 713, thereby protecting the connection portion 713 from excessive elastic deformation caused by interference of the connection portion 713, and affecting the performance of the connection portion 713 in elastically maintaining the relative positions of the first clamping portion 711 and the second clamping portion 712. The body portion 714 and the connection portion 713 are provided at a distance from each other, so that resistance against elastic deformation of the first and second clamping portions 711 and 712 is reduced, compared to the manner in which the body portion 714 and the connection portion 713 are connected.
Referring to fig. 4, the first clamping part 711, the second clamping part 712, the connection part 713, and the limiting part 715 are in one-to-one correspondence, and the number of the first connection part 713, the second clamping part 712, the connection part 713, and the limiting part 715 is adapted to the main body part 714. In the embodiment shown in fig. 1, the number of the first clamping portion 711, the second clamping portion 712, the connecting portion 713, and the limiting portion 715 is 12. The 12 first clamping portions 711, the 12 second clamping portions 712, the 12 connecting portions 713, and the 12 spacing portions 715 are divided into two rows. The main body portion 714 is connected to the first clamping portions 711 of the two rows and surrounds the first clamping portions 711, the connecting portions 713, and the second clamping portions 712 of the two rows. The main body 714 is spaced apart from the two rows of second clamping portions 712, and the main body 714 is also spaced apart from the two rows of connecting portions 713.
Referring to fig. 4, the second clamping portion 712 includes a spacing section 712a and a clamping section 712b. Both ends of the holding section 712b are respectively connected with the connecting portion 713 and the limiting section 712a. The minimum distance between the spacing segment 712a and the first clamping portion 711 is less than the distance between the clamping segment 712b and the first clamping portion 711. One end of the limiting section 712a, which is far away from the clamping section 712b, is provided with a guiding surface 712a1 for guiding the material into between the clamping section 712b and the first clamping part 711. When the material is clamped between the clamping section 712b and the first clamping portion 711, the material is blocked by the limiting portion 715 when leaving the space between the first clamping portion 711 and the second clamping portion 712, so as to improve the difficulty of the material separating from the second clamping member 710 and avoid the material from easily separating from the second clamping member 710. The spacing portion 715 improves the difficulty of the material being separated from the second clamping member 710, and also improves the difficulty of the material entering between the first clamping portion 711 and the second clamping portion 712. The guide surface 712a1 is provided to guide the material into between the first clamping portion 711 and the second clamping portion 712.
Referring to fig. 4, one end of the stopper 715 is connected to the first clamping portion 711, and the other end of the stopper 715 is spaced apart from the clamping segment 712b. A first positioning space 716a and a second positioning space 716b are formed between the clamping section 712b and the first clamping portion 711. The spacing part 715 is located between the first positioning space 716a and the second positioning space 716b. Since the other end of the stopper 715 is spaced apart from the clamping section 712b, the first positioning space 716a and the second positioning space 716b are in communication. The side of the limiting part 715 facing the first positioning space 716a is smoothly connected to the first clamping part 711, and the side of the limiting part 715 facing the second positioning space 716b is smoothly connected to the first clamping part 711. Assuming that the first positioning space 716a is closer to the stop segment 712a than the second positioning space 716b, the material is generally clamped in the first positioning space 716a, and the second positioning space 716b is in a free state. However, during the process of clamping and unclamping the material, the second positioning space 716b is changed along with the movement of the clamping section 712b relative to the first clamping portion 711, so that the resistance of the first clamping portion 711 and the second clamping portion 712 to elastic deformation is reduced.
The first transfer device 100 needs to transfer the material sequentially through the pin device 200, the heating device 300, and the glue application device 400. After the pin device 200 assembles the pin and the material, but the relative positions of the pin and the material are not fixed by glue, the relative positions of the pin and the material are not fixed, and thus the first transfer device 100 needs to clamp the pin and the material by the auxiliary clamp 120 and the first clamp 110 respectively to fix the relative positions of the pin and the material during the transfer process. The diameter of the needle is usually small, and if the auxiliary clamping member 120 adopts an elastic clamping manner, the needle cannot be effectively clamped by the auxiliary clamping member 120. When the material passes through the heating device 300, the heating device 300 needs to heat the material, and thus the first clamping member 110 and the auxiliary clamping member 120 are inevitably heated. If the first clamping member 110 and the auxiliary clamping member 120 adopt an elastic clamping manner, the first clamping member 110 and the auxiliary clamping member 120 are usually made of plastic materials, so that they cannot withstand the heating of the heating device 300. Therefore, the first clamping member 110 and the auxiliary clamping member 120 need to be rigidly clamped to the material. When the needle and the material are on the second transferring device 700, the needle and the material have passed through the first solidifying means 500, so that the relative positions of the needle and the material can be fixed to a certain extent by the glue, and at this time, the second clamping member 710 only clamps the material, and the needle does not move relative to the material. Finally, the second transfer device does not need to provide an auxiliary clamping member 120 for clamping the needle, thereby reducing the cost. The second clamping member 710 adopts an elastic material clamping manner, so that the second clamping member 710 does not need to be opened first when clamping and loosening materials, thereby accelerating the material transferring speed and improving the production efficiency.
Referring to fig. 1 and 5, the plurality of second clamping members 710 are circularly moved by the driving of the second driving member, thereby moving the material clamped by the plurality of second clamping members 710. The materials are sequentially moved to pass through the second solidification device 800, the testing device 900 and the rejecting device 1000 under the driving of the second driving member. The second curing device 800 further cures the glue using a mercury lamp. The test device 900 is used to test whether there is a blockage or leakage of the needle and material after the glue has cured. The reject device 1000 includes a reject driving member 1100 and a reject member 1200. The waste removing driving member 1100 drives the waste removing member 1200 to act on the material, and the material overcomes the resistance of the second clamping member 710 under the action of the waste removing member 1200 to separate from the second clamping member 710, so that the waste removing efficiency is quickened. If the first curing device 500 is only provided, when the previous material is cured by the first curing device 500, the first transferring device 100 needs to wait for curing the glue and cannot transfer the subsequent material, thereby affecting the production efficiency. The curing of the glue is performed by the first curing device 500 and the second curing device 800, respectively, so that after the glue is pre-cured by the first curing device 500, the glue is transferred from the first transferring device 100 to the second transferring device 700, and then transferred to the second curing device 800 by the second transferring device 700 for further curing. When the material is transferred to the second curing device 800 and cured by the second curing device 800, the first transferring device 100 can simultaneously transfer the subsequent material, thereby improving the production efficiency. Ultraviolet lamps generally only promote the surface curing of the glue while curing is performed, whereas curing is not yet usually performed inside the glue. Mercury lamps can promote curing of the interior of the glue as well. Therefore, the ultraviolet lamp and the mercury lamp are matched to realize the solidification of the glue from inside to outside.
Referring to fig. 1 and 2, the transplanting device 600 includes a transplanting drive and a transplanting clamp 610. The transplanting clamping member 610 rigidly clamps the material. When the transplanting device 600 is used for transplanting materials, the transplanting driving part drives the transplanting clamping part 610 to approach and clamp the materials, at this time, the first clamping part 110 is also in a state of clamping the materials, and the auxiliary clamping part 120 is also in a state of clamping the needles. Subsequently, the first clamping member 110 releases the material, the auxiliary clamping member 120 releases the needle, and the transplanting drive drives the transplanting clamping member 610 away from the first clamping member 110. The transplanting drive then drives the transplanting clamp 610 to approach the second clamp 710 and release the material while the second clamp 710 clamps the material. Finally, the transplanting driving member drives the transplanting clamping member 610 to reset so as to facilitate the next transfer. If the transplanting clamping member 610 adopts a manner of elastically clamping the material, the transplanting clamping member 610 and the second clamping member 710 are both elastically clamping the material, so that the material is difficult to transfer from the transplanting clamping member 610 to the second clamping member 710. Thus, the transplanting clamping member 610 needs to be rigidly clamped to the material so that the material can be transferred from the transplanting clamping member 610 to the second clamping member 710.
The embodiment of the invention further provides a medical device production method, which comprises the following steps:
step 1: firstly, assembling a needle and a material;
step 2: a heating pin and a material assembling part;
step 3: applying glue to the needle and material mounting portion;
step 4: pre-curing glue at the needle and material assembly part;
step 5: further curing the glue of the needle and material assembly portion;
step 6: detecting whether the needle and the material after the glue is solidified are blocked or leaked;
step 7: and removing the needles and the materials which do not meet the preset requirements.
It will be appreciated that the heating device 300 may be omitted if the glue itself cures faster. Meanwhile, if the auxiliary clamping member 120 adopts an elastic clamping manner to achieve effective clamping of the needle, the first clamping member 110 and the auxiliary clamping member 120 may also adopt an elastic clamping manner. At this time, the transplanting device 600 and the second transferring device 700 are not required to be provided, and the first transferring device 100 transfers the material to pass through the pin device 200, the glue spreading device 400, the first curing device 500, the second curing device 800, the testing device 900 and the rejecting device 1000 in sequence.
The technical features of the above-described embodiments may be combined in any manner, and for brevity, all of the possible combinations of the technical features of the above-described embodiments are not described, however, all of the combinations of the technical features should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
