Abstract
Description
Technical Field
[0001] This utility model relates to the field of vascular interventional catheter manufacturing technology, specifically to a turnover tooling for the distal tube assembly of a coronary balloon catheter. Background Technology
[0002] In the manufacturing process of coronary balloon dilation catheters, after the balloon and catheter are welded into a distal catheter assembly (also called a balloon catheter semi-finished product) through a welding process, the balloon of the distal catheter assembly needs to be coated with drugs through a coating equipment, and the outer diameter of the balloon catheter is reduced through a balloon folding and squeezing process to facilitate the product entering the blood vessel.
[0003] like Figure 4 As shown, in actual production, when transferring or storing distal tube assemblies between different process equipment, an inverted trapezoidal turnover rack is required (with the balloon on the distal tube assembly suspended in the air). However, during the storage or transfer of distal tube assemblies using the aforementioned turnover rack, the distal tube assemblies are prone to falling due to shaking, leading to damage, contamination, or processing interruption. Furthermore, the distal tube assemblies are placed directly on the turnover rack, which cannot be directly counted, increasing management difficulty and production costs. At the same time, in the coating process, in order to form drug crystals on the surface of the balloon and improve drug stability and release efficiency, a surface treatment device is required to treat the balloon for drug crystallization. However, the existing production method can only remove the distal tube assemblies from the turnover rack one by one and place them into the surface treatment device, which severely restricts the improvement of production efficiency.
[0004] Therefore, how to improve the production efficiency and yield of coronary balloon dilation catheters has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to provide a turnover tooling for distal tube assemblies to solve the technical problem of low production efficiency of coronary balloon dilation catheters.
[0006] The technical solution adopted by this utility model is: a turnover tooling for a remote pipe assembly, comprising:
[0007] Connecting columns;
[0008] A support base is vertically and fixedly connected to the bottom end of the connecting column, and multiple positioning holes are distributed circumferentially on the support base.
[0009] A limiting plate is located directly above the support base. The limiting plate is fixedly connected to the middle of the connecting column, and multiple limiting grooves are distributed circumferentially on the limiting plate. The limiting grooves are located directly above the positioning holes.
[0010] Preferably, the limiting groove includes a connecting section, a transition section, and a limiting section. One end of the connecting section is connected to one end of the transition section, and the other end of the connecting section is connected to the outer circumferential surface of the limiting disk. The limiting section is located on one side of the connecting section, and one end of the limiting section is connected to the other end of the transition section. The other end of the limiting section extends towards the outer circumferential surface of the limiting disk to directly above the positioning hole.
[0011] Preferably, the connecting segment and the limiting segment extend along the radial direction of the limiting disk, and the transition segment is an arc-shaped segment protruding toward the axis of the limiting disk.
[0012] Preferably, the number of limiting grooves is 15 to 25.
[0013] Preferably, the number of limiting grooves is 20.
[0014] Preferably, the limiting plate is provided with numerical markings that correspond one-to-one with the limiting slots.
[0015] Preferably, the top of the connecting column is fixedly fitted with an anti-slip sleeve.
[0016] Preferably, a support leg is fixedly connected to the lower part of the support base.
[0017] Preferably, the connecting column, the supporting base, and the limiting plate are arranged coaxially.
[0018] The beneficial effects of this utility model are:
[0019] This invention employs a combination of vertical support and horizontal limiting. A connecting column secures the upper and lower limiting plates and the support base. Multiple positioning holes are circumferentially distributed on the support base, and multiple limiting grooves that mate with the positioning holes are circumferentially distributed on the limiting plates. When the middle portion of the distal tube assembly passes through the limiting groove and the bottom end of the distal tube assembly is inserted into the positioning hole, the balloon of the distal tube assembly is positioned between the limiting plate and the support base. The support base provides vertical support for the distal tube assembly, while the limiting plate provides horizontal limiting, preventing the distal tube assembly from falling off the turnover fixture in case of shaking, thus ensuring the yield rate of coronary balloon dilation catheters. Simultaneously, the vertical distribution of the distal tube assemblies on the turnover fixture allows them to be directly placed in a surface treatment device for drug crystallization, enabling simultaneous surface treatment of multiple distal tube assemblies and improving the production efficiency of coronary balloon dilation catheters.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0036] Examples, such as Figure 1 , Figure 2 and Figure 3 As shown, a turnover fixture for a remote pipe assembly includes:
[0037] A connecting column 10 is provided, which is set in the vertical direction.
[0038] A support base 20 is vertically and fixedly connected to the bottom end of the connecting column 10, and a plurality of positioning holes 21 are distributed around the circumference of the support base 20.
[0039] A limiting plate 30 is located directly above the support base 20. The limiting plate 30 is vertically fixed to the middle of the connecting column 10, and multiple limiting grooves 31 are distributed around the circumference of the limiting plate 30. The limiting grooves 31 are located directly above the positioning hole 21.
[0040] This utility model employs a combination of vertical support and horizontal limiting. A connecting column 10 securely connects the vertically positioned limiting plate 30 and the supporting base 20. Multiple positioning holes 21 are circumferentially distributed on the supporting base 20, and multiple limiting grooves 31 that mate with the positioning holes 21 are circumferentially distributed on the limiting plate 30. When the middle portion of the distal tube assembly 70 passes through the limiting groove 31 and the bottom end of the distal tube assembly 70 is inserted into the positioning hole 21, the balloon of the distal tube assembly 70 is located between the limiting plate 30 and the supporting base 20. The device 0 provides vertical support for the distal tube assembly 70, while the limiting plate 30 provides horizontal restraint for the distal tube assembly 70 to prevent it from falling off the turnover fixture due to shaking during transfer, thus ensuring the yield of coronary balloon dilation catheters. At the same time, the distal tube assembly 70 is vertically distributed on the turnover fixture, allowing the distal tube assembly 70 and the turnover fixture to be directly placed in the surface treatment equipment for drug crystallization, achieving simultaneous drug crystallization of multiple distal tube assemblies 70, thereby improving the production efficiency of coronary balloon dilation catheters.
[0041] Specific embodiment 1, such as Figure 1 , Figure 2 and Figure 3 As shown, a turnover tooling for distal catheter assemblies is used for storing and transporting distal catheter assemblies during the production process of coronary balloon dilation catheters; the turnover tooling includes:
[0042] A connecting column 10 is provided, which is set in the vertical direction.
[0043] Preferably, an anti-slip sleeve 50 is fixedly fitted at the top of the connecting column 10 to facilitate the movement and turnover of the work equipment by the staff.
[0044] A support base 20 is provided, the upper surface of which is vertically and fixedly connected to the bottom end of the connecting column 10, and a plurality of positioning holes 21 are distributed around the circumference of the support base 20. The positioning holes 21 are blind holes.
[0045] Preferably, the support base 20 is in the shape of a disc, and the support base 20 is coaxially arranged with the connecting column 10, and a plurality of positioning holes 21 are evenly distributed on the support base 20 around the axis of the connecting column 10.
[0046] More preferably, a support leg 60 is fixedly connected below the support base 20. The number of support legs 60 is three, and the three support legs 60 are distributed at the three vertices of the same triangle.
[0047] A limiting plate 30 is located directly above the support base 20. The limiting plate 30 is vertically fixed to the middle of the connecting column 10. The vertical distance between the limiting plate 30 and the support base 20 is greater than the vertical dimension of the balloon of the distal tube assembly 70. A plurality of limiting grooves 31 are distributed circumferentially on the limiting plate 30. The limiting grooves 31 are located directly above the positioning hole 21.
[0048] Preferably, the limiting plate 30 is coaxially arranged with the connecting column 10, and multiple limiting grooves 31 are evenly distributed on the limiting plate 30 around the axis of the connecting column 10.
[0049] More preferably, the number of limiting grooves 31 is 15 to 25.
[0050] Preferably, the number of limiting grooves 31 is 20.
[0051] It should be noted that the limiting groove 31 can adopt any limiting groove structure that can horizontally limit the distal tube assembly 70. The following is only an example to illustrate one of them in detail.
[0052] The limiting groove 31 includes a connecting section 32, a transition section 33, and a limiting section 34. The connecting section 32 extends along the radial direction of the limiting disk 30, that is, the groove length direction of the connecting section 32 is the radial direction of the limiting disk 30. One end of the connecting section 32 is connected to one end of the transition section 33, and the other end of the connecting section 32 is connected to the outer circumferential surface of the limiting disk 30. That is, the other end of the connecting section 32 penetrates the limiting disk 30, so that the distal tube assembly 70 can enter the limiting groove 31 through the connecting section 32.
[0053] The transition section 33 is an arc-shaped section protruding toward the axis of the limiting disk 30, and one end of the transition section 33 is connected to the connecting section 32, while the other end of the transition section 33 is connected to the limiting section 34, so that the limiting groove 31 is J-shaped as a whole.
[0054] The limiting segment 34 is located on one side of the connecting segment 32 and extends radially along the limiting disk 30. One end of the limiting segment 34 is connected to the other end of the transition segment 33, and the other end of the limiting segment 34 extends towards the outer circumferential surface of the limiting disk 30 to directly above the positioning hole 21. This allows the distal tube assembly 70 to move vertically and smoothly insert into the positioning hole 21 of the support base 20 after entering the limiting segment 34 through the connecting segment 32 and the transition segment 33. At the same time, the limiting segment 34 horizontally limits the distal tube assembly 70, preventing it from coming out of the limiting groove 31 due to shaking.
[0055] Preferably, the limiting plate 30 is provided with a number 40 that corresponds one-to-one with the limiting groove 31. The number 40 starts from 1 and is arranged on the limiting plate 30 from smallest to largest. The position of each number 40 corresponds to the position of each limiting groove 31, so as to quickly identify the number of remote tube assemblies 70 on the turnover tooling.
[0056] The usage process of the remote tube assembly of this utility model is as follows:
[0057] After fixing multiple remote pipe assemblies into the limiting grooves of the turnover fixture in sequence, the turnover fixture can be moved by holding the top of the connecting column to realize the storage and transfer of the remote pipe assemblies.
[0058] When performing drug crystallization, the distal tube assembly can be sent into the surface treatment equipment along with the turnover tooling as a whole. After the treatment is completed, the turnover tooling and the distal tube assembly can be taken out together. The distal tube assemblies can be released one by one through a simple operation, without having to pick them up and put them back one by one, which reduces the risk during the transfer process.
[0059] Compared with the prior art, the present invention has at least the following beneficial technical effects:
[0060] This invention enables simultaneous processing of multiple workpieces (remote tube assemblies), significantly improving production efficiency.
[0061] This invention effectively fixes the workpiece by using a limiting groove, avoiding the risk of it falling during transportation and enhancing safety.
[0062] This invention allows for the direct acquisition of workpiece quantity through digital markings on the turnover tooling, simplifying the management process and facilitating management.
[0063] This invention reduces workpiece damage and processing interruptions, thereby lowering production costs.
[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
