[0002] Medical devices refer to instruments, equipment, appliances, materials, or other articles used alone or in combination on the human body, including the necessary software; their effects on the human body surface and inside the body are not achieved through pharmacological, immunological, or metabolic means, but these means may be involved and play a certain auxiliary role; currently, balloon stents are very common products in medicine. The balloon stent is a circular, thin-walled, expandable metal structure that includes a single valve and is designed to fill the lumen of a saccular aneurysm; the balloon stent is constructed to attach to a delivery catheter, compress, push through the vascular system, expand within the lumen of the saccular aneurysm, and then separate from the delivery catheter; delivery catheters of various sizes, shapes, materials, and constructions can be used to position the compressed balloon stent in the saccular aneurysm, and the balloon stent can be expanded in the aneurysm by allowing fluid or solid to flow through the delivery catheter and into the central space or space of the balloon stent.

[0003] Existing balloon stents typically consist of a balloon frame, a catheter, and a neck collar. During the manufacturing process, the neck collar needs to be welded to the balloon frame first, and then the balloon frame with the neck collar welded on is welded to the catheter. However, the welding operation between the existing balloon frame and the neck collar is mainly done manually, which results in relatively low manufacturing efficiency, unstable quality, and low yield. This makes it unsuitable for users' large-scale production and has a limited range of applications.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of the above, this utility model addresses the deficiencies of the existing technology, and its main objective is to provide a medical balloon stent processing equipment that realizes the automated production of stents and neck rings. Furthermore, the first positioning mechanism ensures that the neck ring is clamped and positioned at the first placement part before being connected and fitted with the stent, guaranteeing accurate positioning between the stent and the neck ring. Additionally, the first rotating unit enables multi-directional welding operations of the stent and neck ring, improving production efficiency and welding quality, meeting the needs of users for mass production, and having a wide range of applications.

The dust collection device is used to collect the waste generated when the polishing disc contacts the first placement part for polishing.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves automated production of the bracket and neck ring by designing various mechanisms, using a gripping and conveying mechanism to grip the bracket and neck ring in the feeding area and place them on the first placement part, and then welding them together with a welding head and using the gripping and conveying mechanism to grip and place them in the discharge area. At the same time, the setting of the first positioning mechanism ensures that the neck ring is clamped and positioned in the first placement part before connecting and cooperating with the bracket, which helps to ensure the accurate positioning of the bracket and neck ring. Furthermore, the setting of the first rotating unit enables multi-directional welding operations of the bracket and neck ring.

[0021] Furthermore, the second detection device is used to detect the mating position of the collar and bracket on the first placement section. Together with the adjustment mechanism, it adjusts the bracket if the position is incorrect, thereby ensuring that the mating position between the collar and bracket is accurate. This is beneficial for subsequent welding operations between the collar and bracket, reducing welding defects and making it highly practical. At the same time, the third detection device is used to detect the dimensions of the bracket and collar before welding, avoiding welding operations on brackets and collars with unqualified dimensions. Together with the pressure holding component, it clamps and holds unqualified brackets and collars under pressure, and then detects them after pressure holding. Based on the detection results, they are moved to the first placement section or to the defective product area, reducing product production costs and rework rates.

[0022] Furthermore, the first grinding mechanism is set according to the usage time or welding quantity of the welding head, and performs grinding and maintenance on the welding head when the settings are met, to ensure the welding effect of the subsequent bracket and neck ring, thereby ensuring the welding quality of the product. At the same time, the second grinding mechanism is set to grind and maintain the surface of the first placement part, to grind the waste generated during welding that accumulates on the surface of the first placement part, to ensure the placement and positioning of the neck ring and bracket on the first placement part, and to ensure good usability.

[0055] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0056] A medical spherical stent processing device includes a body 10 and a gripping and transferring mechanism 20, a welding mechanism 30, and a first positioning mechanism 40 disposed on the body 10; wherein:

[0057] The machine body 10 has a feeding area 11 and a discharging area 12. The gripping and conveying mechanism 20 and the welding mechanism 30 are located between the feeding area 11 and the discharging area 12. The welding mechanism 30 includes a welding seat 31, a welding head 32 and a first displacement module 33. The welding seat 31 has a first placement part 311 for placing a bracket and a neck collar. The first placement part 311 is rotatably mounted on the welding seat 31 via a first rotating unit 312. The first displacement module 33 is driven to connect to the welding head 32 to control the welding head 32 to move closer to the first placement part 311 for welding operations or move away from the first placement part 311.

[0058] The first positioning mechanism 40 is disposed on one side of the welding seat 31. The first positioning mechanism 40 includes a first automatic chuck assembly 41 and a second displacement module 42 for driving the first automatic chuck assembly 41 to move. The first automatic chuck assembly 41 moves closer to the first placement part 311 to clamp the positioning collar or release the collar away from the first placement part 311 under the control of the second displacement module 42.

[0059] The gripping and transferring mechanism 20 reciprocates between the loading area 11, the welding seat 31, and the unloading area 12 to grip and transfer the bracket and neck ring from the loading area 11 to the welding seat 31, and then transfers the welded bracket and neck ring to the unloading area 12. Thus, through the design of each mechanism, the gripping and transferring mechanism 20 grips the bracket and neck ring from the loading area 11 and places them on the first placement part 311. The welding head 32 then welds and fixes them together, and the gripping and transferring mechanism 20 grips and places them on the unloading area 12, achieving automated production of the bracket and neck ring. Simultaneously, the first positioning mechanism 40 ensures that the neck ring is clamped and positioned in the first placement part 311 before connecting and cooperating with the bracket, guaranteeing accurate positioning between the bracket and neck ring. Furthermore, the first rotating unit 312 enables multi-directional welding operations for the bracket and neck ring. The ingenious and reasonable structural design improves production efficiency and welding quality, meeting the needs of users for mass production and has a wide range of applications.

[0060] It also includes a second positioning mechanism 50 for engaging and positioning the bracket and the neck ring on the first placement part 311. The second positioning mechanism 50 is disposed on the side of the first positioning mechanism 40. The second positioning mechanism 50 has a locking block 51 and a third displacement module 52 for driving the locking block 51 to move. Specifically, both the bracket and the neck ring are provided with locking holes for engagement and positioning. When the neck ring and the bracket are connected in the first placement part, the locking holes of the bracket and the neck ring are correspondingly set. The locking block is engaged in the locking holes of the bracket and the neck ring under the control of the third displacement module, so as to realize the engagement and positioning of the neck ring and the bracket in the first placement part.

[0061] In use, the gripping and transferring mechanism 20 grips and moves the neck collar from the loading area 11 and places it on the first placement part 311. Under the control of the second displacement module 42, the first automatic chuck assembly 41 moves to the first placement part 311 and clamps and positions the neck collar on the first placement part 311. The gripping and transferring mechanism 20 then grips and moves the bracket from the loading area 11 and places it on the first placement part 311 so that the bracket contacts and positions the neck collar. Then, the locking block 51 moves toward the first placement part 311 under the control of the third displacement module 52 and clamps and positions the bracket and neck collar on the first placement part 311. The first automatic chuck assembly 41 releases the neck collar and moves away from the first placement part 311. Under the control of the first displacement module 33, the welding head 32 moves toward the bracket and neck collar in the first placement part 311 and performs welding operations. After welding is completed... Afterwards, the welding head 32 moves away from the first placement part 311, the locking block 51 separates from the bracket and neck ring, the first rotating unit 312 controls the first placement part 311 to rotate in conjunction with the bracket and neck ring, and rotates the other welding positions of the bracket and neck ring to a direction close to the welding head 32. Then, the locking block 51 contacts and positions the bracket and neck ring. Under the control of the first displacement module 33, the welding head 32 moves toward the bracket and neck ring of the first placement part 311 and performs welding operations. This cycle is repeated to weld and fix the multiple welding positions required between the bracket and neck ring. Thus, the second positioning mechanism 50 is set so that after the neck ring and bracket are connected and engaged in the first placement part 311, the locking block 51 locks and positions them in the first placement part 311, so as to avoid the neck ring and bracket from shifting during the subsequent welding process, which has good usability.

[0062] Preferably, the feeding area 11 is provided with a neck ring tray 111 and a support tray 112. The machine body 10 is provided with an identification device 13 for identifying the position information of the support and neck ring in the neck ring tray 111 and the support tray 112. The identification device 13 is located above the feeding area 11. Thus, the identification device 13 is set so that the gripping and transferring mechanism 20 can grip and transfer the workpieces in the corresponding trays according to the feedback of the position information of the corresponding trays from the identification device 13, ensuring that the neck ring and support are correctly placed on the first placement part 311, thereby improving the welding quality of the product.

[0063] Specifically, a first detection device 14 for detecting whether the welding effect of the bracket and collar is qualified is provided between the welding mechanism 30 and the discharge area 12. A defective product storage area 15 is provided on the machine body 10. The defective product storage area 15 is located next to the discharge area 12. The gripping and transferring mechanism 20 moves the welded bracket and collar to the first detection device 14. When the first detection device 14 detects that the welding effect between the bracket and collar is unqualified, the gripping and transferring mechanism 20 moves the unqualified product to the defective product storage area 15 and places it there. When the first detection device 14 detects that the welding effect between the bracket and collar is qualified, the gripping and transferring mechanism 20 moves the qualified product to the discharge area 12 and places it there. In this way, the first detection device 14 is set up to detect whether there is a welding defect in the product, and the gripping and transferring mechanism 20 places it in the discharge area 12 or the defective product area according to the detection result, so as to facilitate the user's subsequent storage and rework of products and defective products.

[0064] Furthermore, the body 10 is equipped with a second detection device 16 for detecting whether the mating position between the bracket and the neck collar is accurate. The second detection device 16 is located behind the welding seat 31. An adjustment mechanism 60 is also provided for adjusting the mating position between the bracket and the neck collar. The adjustment mechanism 60 is located above the first detection mechanism. The adjustment mechanism 60 includes a second automatic chuck assembly 61 and a fourth displacement module 62 for controlling the displacement of the second automatic chuck assembly 61. The fourth displacement module 62 controls the second automatic chuck assembly 61 to move to the next position based on feedback from the second detection device 16. At the first placement part 311, the bracket is clamped by the second automatic chuck assembly 61 and the fourth displacement module 62 controls the second automatic chuck assembly 61 to drive the bracket to move, thereby adjusting the mating position between the bracket and the neck collar. Thus, the second detection device 16 is set to detect the mating position of the neck collar and the bracket on the first placement part 311. With the setting of the adjustment mechanism 60, the bracket with incorrect position is adjusted, thereby ensuring that the mating position between the neck collar and the bracket is accurate. This is beneficial to the subsequent welding operation between the neck collar and the bracket, reduces the occurrence of welding defects in the product, and has strong practicality.

[0065] The body 10 is equipped with a third detection device (not shown in the figure) for detecting the size information of the bracket and neck collar. The third detection device is located on one side of the gripping and transferring mechanism 20. A pressure holding component 17 is also provided on the other side of the gripping and transferring mechanism 20. The pressure holding component 17 includes a base 171, a pressure holding clamp 172 and a first driving device 173. The base 171 is provided with a second placement part 174 for placing the bracket and neck collar. The pressure holding clamp 172 is located on one side of the second placement part 174. The first driving device 173 is driven to connect to the pressure holding clamp 172 to clamp or release the bracket and neck collar on the second placement part 174. The gripping and transferring mechanism 20 moves back and forth to the third detection device and the pressure holding component 17.

[0066] In use, the gripping and transferring mechanism 20 grips and transfers the brackets and collars in the loading area 11 one by one to the third inspection device for size inspection. Based on the feedback from the second inspection device 16, the gripping and transferring mechanism 20 places brackets and collars that do not meet the preset values ​​into the pressure holding component 17 for pressure holding operation, or places brackets and collars that meet the preset values ​​into the first placement part 311 for welding operation. After the pressure holding of the brackets and collars is completed, the gripping and transferring mechanism 20 grips and transfers them again to the third inspection device for size inspection. When the inspection result is still the preset value, the gripping and transferring mechanism 20 grips and transfers them to the defective product area. Thus, the third inspection device is set up so that the brackets and collars are size inspected before welding, avoiding welding of brackets and collars that do not meet the size requirements. With the setting of the pressure holding component 17, the defective brackets and collars are clamped and pressure-held, and then inspected again after pressure holding. Based on the inspection result, they are moved to the first placement part 311 or to the defective product area, reducing the product rework rate.

[0067] Furthermore, the machine body 10 is provided with a first grinding mechanism 70 for grinding the welding head 32. The first grinding mechanism 70 is located to the right of the welding seat 31 and behind the welding head 32. The first grinding mechanism 70 includes a mounting base 71, a sandpaper conveying device 72, a sandpaper winding device 73, and a collection box 74. The mounting base 71 has a grinding table 711. The sandpaper on the sandpaper conveying device 72 passes through the grinding table 711 and is wound onto the sandpaper winding device 73. The collection box 74 is located below the grinding table 711. Thus, the setting of the first grinding mechanism 70 is set according to the usage time or welding quantity of the welding head 32, and the welding head 32 is ground and maintained when the setting is met, so as to ensure the welding effect of the subsequent bracket and neck ring, thereby ensuring the welding quality of the product.

[0068] It also includes a second polishing mechanism 80 for polishing the surface of the first placement part 311. The second polishing mechanism 80 includes a movable base 81, a polishing disc 82, a dust collection device 83, and a fifth displacement module 84. The movable base 81 is located behind the welding base 31. The polishing disc 82 is located on the front side of the movable base 81. The dust collection device 83 is located below one side of the welding base 31. The fifth displacement module 84 is driven and connected to the movable base 81 so that the polishing disc 82 of the movable base 81 approaches the welding base 31 and contacts the first placement part 311 for polishing. The dust collection device 83 is used to collect the waste generated when the polishing disc 82 contacts the first placement part 311 for polishing. Thus, the second polishing mechanism 80 is set up to polish and maintain the surface of the first placement part 311, and to polish the waste generated during welding that accumulates on the surface of the first placement part 311, ensuring the placement and positioning of the collar and bracket on the first placement part 311, with good usability.

[0069] In this embodiment, the gripping and transferring mechanism 20 includes a robotic arm 21, a turntable 22, a support gripping head 23, a collar gripping head 24, and a finished product gripping head 25. The support gripping head 23, the collar gripping head 24, and the finished product gripping head 25 are arranged at intervals around the outer diameter of the turntable 22 at one end of the turntable 22. The other end of the turntable 22 is connected to the upper end of the robotic arm 21 by a second rotating unit 26 for controlling the vertical and horizontal rotation of the turntable 22. The lower end of the robotic arm 21 is provided with a sixth displacement module 27 for driving the robotic arm 21 to reciprocate between the loading area 11, the unloading area 12, the defective product area, the first detection device 14, the third detection device, the welding seat 31, and the pressure holding assembly 17.

[0070] Preferably, the first detection device 14, the second detection device 16 and the third detection device are all CCD detection devices.

[0071] The key design feature of this utility model lies in its various mechanisms. A gripping and conveying mechanism picks up the support and neck ring from the loading area and places them on the first placement part. A welding head then welds and fixes them together, and the gripping and conveying mechanism picks them up again and places them on the unloading area. This achieves automated production of the support and neck ring. Furthermore, the first positioning mechanism ensures that the neck ring is clamped and positioned on the first placement part before connecting and engaging with the support, guaranteeing accurate positioning between the support and neck ring. Additionally, the first rotating unit enables multi-directional welding operations on the support and neck ring. The ingenious and reasonable structural design improves production efficiency and welding quality, meeting the needs of users for mass production and has a wide range of applications.

[0072] Secondly, the second positioning mechanism is designed so that after the collar and bracket are connected and fitted in the first placement part, they are locked together and positioned in the first placement part by a locking block, so as to avoid the collar and bracket from shifting during the subsequent welding process, thus improving usability. At the same time, the first detection device is set up to detect whether there are welding defects in the product, and the gripping and transferring mechanism is used to place it in the discharge area or the defective product area according to the detection results, so as to facilitate the user's subsequent storage and rework of products and defective products.

[0073] Furthermore, the second inspection device is designed to inspect the mating position of the collar and bracket on the first placement section. Combined with the adjustment mechanism, it adjusts brackets that are not in the correct position, thereby ensuring that the mating position between the collar and bracket is accurate. This facilitates subsequent welding operations between the collar and bracket, reduces welding defects, and is highly practical. At the same time, the third inspection device is designed to inspect the dimensions of the bracket and collar before welding, preventing the welding of brackets and collars that do not meet the size requirements. Combined with the pressure holding component, it clamps and holds the unqualified brackets and collars under pressure, and then inspects them after pressure holding. Based on the inspection results, they are moved to the first placement section or to the defective product area, reducing the rework rate of the products.

[0074] Furthermore, the first grinding mechanism is set according to the usage time or welding quantity of the welding head, and performs grinding and maintenance on the welding head when the settings are met, to ensure the welding effect of the subsequent bracket and neck ring, thereby ensuring the welding quality of the product. At the same time, the second grinding mechanism is set to grind and maintain the surface of the first placement part, to grind the waste generated during welding that accumulates on the surface of the first placement part, to ensure the placement and positioning of the neck ring and bracket on the first placement part, and to ensure good usability.
