DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0025] Referring to Figure 1 , in an embodiment of the present application of the present utility model, a fixing tooling is disclosed, which includes an I-shaped carrier 10 and an additional carrier 20. The I-shaped carrier 10 includes a first base 11 and a second base 13 arranged in parallel. A first limiting portion 12 for placing a first bonding part 30 is provided on the first base 11; a second limiting portion 14 is provided at a position on the second base 13 opposite to the first limiting portion 12, and the second limiting portion 14 is used for placing a second bonding part 40 bonded to the first bonding part 30; the additional carrier 20 is connected to the I-shaped carrier 10, and the additional carrier 20 is used for carrying a curing device 50, and the curing device 50 is used for curing and connecting the bonding portion of the first bonding part 30 and the second bonding part 40.

[0026] The fixing tooling disclosed in this embodiment is used for the production and processing of medical devices, and can limit two bonding parts to improve the stability of docking and maintain the docking state during bonding and fixing.

[0027] For example, in the production and processing process of an interventional catheter, the outer sheath and the front end head need to be docked. The outer sheath and the head can be used as the first bonding part 30 and the second bonding part 40 respectively, assembled on the fixing tooling to apply glue, and then cured to achieve the connection effect; the rear end of the outer sheath also needs to be docked with a luer connector. Similarly, the fixing tooling disclosed in this embodiment can be used. The luer connector and the outer sheath are respectively assembled on the first base 11 and the second base 13, limited by the first limiting portion 12 and the second limiting portion 14 to maintain a predetermined docking state, then apply glue at the contact position, heat through the curing device 50 on the additional carrier 20, and after the adhesive is cured, the connection is completed. It can be seen that the fixing tooling disclosed in this embodiment can be used for the bonding processing of multiple parts, has strong versatility, is convenient for reducing the manufacture of processing devices, continuously works at the same station, shortens the operation time, and can also reduce the maintenance time of the processing production line.

[0028] Specifically, the curing device 50 disclosed in this embodiment includes, but is not limited to, any one of a hair dryer, a heating cylinder, and a UV lamp head. By heating the adhesive or blowing hot air, the curing speed can be accelerated, which is beneficial to improving the bonding processing speed and thus improving the production efficiency.

[0029] In this embodiment, the first base 11 and the second base 13 are arranged in parallel, and the first limiting portion 12 faces the second limiting portion 14 directly. Thus, after the first bonding part 30 and the second bonding part 40 are assembled, the two are kept in the same straight-line direction, which is beneficial to maintaining the docking state and reducing the probability of deviation or dislocation.

[0030] Specifically, during processing, the first bonding part 30 and the second bonding part 40 are respectively placed on the first limiting portion 12 and the second limiting portion 14 to maintain stability and reduce the risk of dislocation and separation during the glue application and curing processes. After the glue is applied, the curing device 50 fixed by the additional carrier 20 heats the glue application position, that is, heats the bonding position of the first bonding part 30 and the second bonding part 40, so that the adhesive is cured to achieve the effect of fixedly connecting the two.

[0031] It can be seen that the fixing tooling disclosed in this embodiment can provide stable support, replace the manual fixing method, improve the stability of the two bonding parts and the curing device 50 during the bonding operation, reduce the deviation during the bonding process, and thus facilitate improving the production efficiency and increasing the product consistency and stability.

[0032] As Figure 1 shown, as an implementation manner of this embodiment, it is disclosed that the first limiting portion 12 is an annular convex platform, a limiting groove 121 is formed inside the first limiting portion 12, and the limiting groove 121 is used to accommodate the first bonding part 30; the second limiting portion 14 is a notch penetrating through the second base 13, and the notch is coaxially arranged with the first limiting portion 12.

[0033] The annular convex platform disclosed in this embodiment protrudes on the first base 11, limits the first bonding part 30 in the limiting groove 121, and restricts the first bonding part 30 through the inner wall of the annular convex platform, so as to keep the first bonding part 30 stably placed in the annular convex platform and avoid lateral sliding.

[0034] In other embodiments, the first limiting portion 12 may also be an annular groove dug on the first base 11, and the inner wall of the annular groove is used to limit the first bonding part 30.

[0035] In other embodiments, a positioning post is provided at the central position of the first limiting portion 12 for inserting the first bonding part 30 to further fix the first bonding part 30.

[0036] In other embodiments, the second limiting portion 14 may also be a through hole penetrating through the second base 13 for inserting the second bonding part 40, and no further limitation will be made here one by one.

[0037] Specifically, as another implementation manner of this embodiment, it is disclosed that an opening 141 penetrating the edge of the second base 13 is formed on the side surface of the notch, and the opening 141 is used to facilitate the insertion of the second bonding part 40.

[0038] In this embodiment, directly above the first bonding part 30 is the notch. The second bonding part 40 is inserted laterally into the notch from the opening 141 and is limited by the side wall of the notch, so that the second bonding part 40 is limited directly above the first bonding part 30. Therefore, the two are coaxially arranged, and accurate alignment can be achieved to facilitate plug-in connection.

[0039] Specifically, during the actual operation process, for example, after the bonding of the intervention catheter is completed, one end of the intervention catheter (the second bonding part 40) is laterally removed from the opening 141, and then the catheter end (the first bonding part 30) is pulled out from the annular boss. If the lateral opening 141 is not provided on the second limiting part 14, it is necessary to pull out the ultrasonic catheter from the notch after bonding, resulting in the ultrasonic end also passing through the notch, which is likely to cause friction and collision with the second base 13, possibly damaging the product. Similarly, it is also convenient to place the second bonding part 40 from the side before bonding, which is beneficial not only to rapid assembly and improvement of processing efficiency, but also to rapid disassembly of the assembled product to protect the integrity of the product.

[0040] As Figure 2 and Figure 3 As shown, as another implementation manner of this embodiment, it is disclosed that a working table surface 111 is formed on one side of the first base 11 facing the second base 13, and the first limiting part 12 is arranged on the working table surface 111; the second base 13 is parallel to the working table surface 111; the working table surface 111 is an inclined table surface, and the inclination direction of the working table surface 111 is opposite to the direction of the opening 141.

[0041] In this embodiment, the working table surface 111 disclosed is inclined in a direction opposite to the direction of the opening 141. Therefore, after the first bonding part 30 and the second bonding part 40 are assembled, the center of gravity of the entire product faces away from the side of the opening 141, thereby avoiding the situation that the product formed by connecting the first bonding part 30 and the second bonding part 40 slides out from the opening 141 under the influence of its own weight, and further improving the stability of the product on the fixing tooling. This inclination direction is also more convenient for bonding operations.

[0042] Specifically, as Figure 2As shown, in another implementation manner of this embodiment, the inclination angle of the workbench surface 111 is α, and the angle size is 3 - 10°. In this embodiment, the first bonding part 30 and the second bonding part 40 are placed on the workbench surface 111. Therefore, it should not be too inclined to avoid the disassembly of the first bonding part 30 or the second bonding part 40 and prevent the product from separating due to the influence of gravity. In addition, when applying glue, if the postures of the first bonding part 30 or the second bonding part 40 are too inclined, it will cause the adhesive to flow, affecting the bonding effect of the contact part and even resulting in glue leakage, making it impossible to complete the connection.

[0043] In addition, if the workbench surface 111 is too inclined, it is easy to cause the center of gravity of the fixing fixture to shift, affecting the stability of its own structure. On this basis, a certain number of threaded holes can be provided on the bottom surface of the I-shaped carrier 10, and the I-shaped carrier 10 can be fixed on the desktop or the operating table surface by screwing, improving the stability of the carrier.

[0044] Specifically, as an implementation manner of this embodiment, it is disclosed that the first limiting part 12 and the first base 11 are integrally formed. The first limiting part 12 disclosed in this embodiment protrudes on the first base 11, and the processing flow can be simplified and the manufacturing can be facilitated through integral forming.

[0045] As Figure 2 and Figure 3 shown, as another implementation manner of this embodiment, it is disclosed that the I-shaped carrier 10 includes a connecting substrate 15. One end of the connecting substrate 15 is connected to the first base 11, and the other end is connected to the second base 13; a sliding groove 151 is provided on the connecting substrate 15, and the sliding groove 151 extends along the connection direction of the first base 11 and the second base 13; the additional carrier 20 is adjustably arranged on the sliding groove 151.

[0046] In this embodiment, the connecting substrate 15 serves as a connecting part to connect the first base 11 and the second base 13 into one body. In the actual manufacturing process, the first base 11, the connecting substrate 15, and the second base 13 can be integrally formed, thus simplifying the processing technology of the I-shaped carrier 10 and reducing costs. For example, plastic or metal materials can be used and integrally formed through a mold. In addition, according to actual needs, the connecting substrate 15 can also be manufactured separately and then connected to the first base 11 and the second base 13 by screwing, clamping, welding, etc. The production process of the I-shaped carrier 10 can be flexibly set according to needs.

[0047] Specifically, in this embodiment, the connecting substrate 15 can also be assembled with an additional carrier 20 by providing a sliding groove 151. The additional carrier 20 slides in the sliding groove 151, thereby driving the curing device 50 to move to cope with bonding parts of different sizes. In actual operation, when the first bonding part 30 and the second bonding part 40 of different sizes are butted, the contact positions may be at different heights. Therefore, for different usage scenarios, by adjusting the position of the additional carrier 20, the curing device 50 is driven to reciprocate between the first base 11 and the second base 13, so that the curing device 50 can always convey hot air towards the bonding position or heat, thereby improving the curing efficiency.

[0048] As Figure 3 shown, as another implementation manner of this embodiment, it is disclosed that there are two sliding grooves 151, and the two sliding grooves 151 are respectively arranged on both sides of the position where the first limiting portion 12 projects on the connecting substrate 15.

[0049] In this embodiment, by providing two sliding grooves 151, two additional carriers 20 can be correspondingly provided, so as to assemble two curing devices 50, which are respectively located on both sides of the first limiting portion 12. In this way, during the curing process, the curing devices 50 on both sides heat or blow air simultaneously, so that the curing efficiencies on both sides of the first bonding part 30 and the second bonding part 40 are the same, improving the curing efficiency and curing uniformity, thereby improving the consistency of the final product and enhancing the product quality.

[0050] It should be noted that in this embodiment, only the number of the sliding grooves 151 is exemplified. According to actual needs, a plurality of sliding grooves 151 can be provided on the connecting substrate 15 to facilitate carrying a plurality of curing devices 50 and flexibly adjusting the blowing and heating directions to meet the usage requirements during the processing.

[0051] Again, as Figure 3 shown, as another implementation manner of this embodiment, it is disclosed that the additional carrier 20 includes a connecting portion 21 and a clamping portion 22. One end of the connecting portion 21 is slidably connected to the sliding groove 151; the other end of the connecting portion 21 is hinged to the clamping portion 22.

[0052] In this embodiment, the additional carrier 20 is used to carry the curing device 50, and the curing device 50 faces the bonding position of the first bonding part 30 and the second bonding part 40. For the processing scenarios of the first bonding part 30 and the second bonding part 40 of different sizes, it may be necessary to adjust the posture of the curing device 50. Therefore, the additional carrier 20 is set as two parts. The connecting portion 21 is used for the connecting substrate 15, and the clamping portion 22 is hinged to the connecting portion 21, so that the direction can be freely adjusted, enabling the curing device 50 to work efficiently and achieving a good effect of curing the adhesive.

[0053] Specifically, the clamping portion 22 and the connecting portion 21 disclosed in this embodiment can be connected by a ball head connection to further improve the flexibility of the clamping portion 22. Furthermore, in order to fix the direction of the curing device 50, the ball head between the clamping portion 22 and the connecting portion 21 can be provided with damping, so as to achieve the effect of stopping as the rotation progresses.

[0054] For example Figure 3 As shown, as another implementation of this embodiment, it is disclosed that the clamping part 22 includes a hinged body, a first clamping plate 222 and a second clamping plate 223, and the hinged body is hinged to the connecting part 21; the first clamping plate 222 and the second clamping plate 223 are arranged in parallel on the side of the hinged body away from the connecting part 21; a clamping hole 221 is formed between the first clamping plate 222 and the second clamping plate 223; a first matching hole 2221 is formed on the first clamping plate 222 extending to the side of the clamping hole 221 away from the hinged body; a second matching hole 2231 is formed on the second clamping plate 223 extending to the side of the clamping hole 221 away from the hinged body; the first matching hole 2221 and the second matching hole 2231 are arranged opposite to each other and are used to assemble fasteners to tighten the clamping hole 221.

[0055] In this embodiment, the hinged body is connected to the connecting part 21, which is connected to the first clamping plate 222 and the second clamping plate 223 as a whole. A clamping hole 221 is formed between the first clamping plate 222 and the second clamping plate 223, and the curing device 50 is inserted into the clamping hole 221 for use. After the curing device 50 is aligned with the bonding position of the first bonding part 30 and the second bonding part 40, the first clamping plate 222 and the second clamping plate 223 are pushed closer to each other by the fastener, thereby shrinking the clamping hole 221, and the curing device 50 is fixed by the friction force of the first clamping plate 222 and the second clamping plate 223. Specifically, the fastener includes but is not limited to bolts, electromagnets, etc.

[0056] Specifically, in another implementation of this embodiment, the first base 11 and / or the second base 13 and / or the connecting substrate 15 are disclosed to be an integrated design. The integrated molding method simplifies the production process and facilitates manufacturing. In addition, the integrated structure has strong mechanical properties and can provide a stable support effect.

[0057] Specifically, in another implementation of the present embodiment, the edges of the I-shaped carrier 10 are all chamfered, and are made of aluminum alloy or stainless steel material, so as to be used in a Class 10,000 clean room.

[0058] In summary, the present application discloses a fixing fixture, which includes an I-shaped carrier 10 and an additional carrier 20. The I-shaped carrier 10 includes a first base 11 and a second base 13 arranged in parallel. A first limiting portion 12 for placing a first bonding part 30 is provided on the first base 11. A second limiting portion 14 is provided at a position on the second base 13 opposite to the first limiting portion 12. The second limiting portion 14 is used for placing a second bonding part 40 bonded to the first bonding part 30. The additional carrier 20 is connected to the I-shaped carrier 10, and the additional carrier 20 is used for carrying a curing device 50 that heats the bonding position facing the first bonding part 30 and the second bonding part 40. The fixing fixture disclosed in this embodiment is used for the production and processing of medical devices. It has good overall stability, a simple structure, low manufacturing cost, and is easy to operate. The fixing fixture provides stable support to improve the stability of the two bonding parts and the curing device 50 during the bonding operation, reduce the deviation during the bonding process, thereby facilitating the improvement of production efficiency, and increasing the product consistency and stability.

[0059] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0060] It should be noted that the present utility model takes the fixing fixture for medical device production as an example to introduce the specific structure and working principle of the present utility model.
