[0002] With the continuous advancement of medical technology, medical catheters are playing an increasingly important role in clinical medicine, becoming an indispensable tool for many treatments. Especially in the field of cardiovascular disease treatment, balloon catheters, as an important type of interventional medical device, are widely used in the treatment of various cardiovascular diseases such as coronary artery disease and vascular stenosis.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This application provides an automatic welding device for balloon tubes, which solves the problem that the automation level of welding equipment in the prior art is still low, and most equipment still relies on semi-automatic welding mode. In this mode, each production process operates independently, requiring a large amount of manual operation, which not only directly leads to low production efficiency, but also makes it difficult to effectively guarantee the consistency of product quality, ultimately resulting in a low overall yield rate. This application utilizes an automatic loading and unloading mechanism to clamp and transport the outer tube and transition tube. An outer tube positioning mechanism automatically determines the length, cuts, and flares the outer tube before inserting the mandrel. Similarly, a transition tube positioning mechanism automatically determines the length, cuts, and flares the transition tube before inserting the mandrel. A heat shrink tubing loading mechanism automatically determines the length and cuts the heat shrink tubing. A heat shrink tubing transfer mechanism automatically transports the cut heat shrink tubing. A stripping mechanism automatically clamps the heat shrink tubing and inserts the outer tube and transition tube, which are then fitted with the mandrel. A welding and peeling mechanism automatically guides the heat shrink tubing with the outer tube and transition tube inserted, welds the outer tube and transition tube, and removes excess tubing. The overall automation level is high, the welding efficiency of the airbag outer tube and transition tube is high, and the fully automated, unmanned production saves significant labor costs. The operation process is simple, the structure is safe and reliable, and the product consistency is good.

[0020] Please refer to the following examples for details: Reference Figures 1-14 The present invention provides an embodiment of an automatic welding device for balloon outer tubes, the specific structure of which includes: a loading and unloading mechanism 1, an outer tube positioning mechanism 2, a transition tube positioning mechanism 3, a heat shrink tubing loading mechanism 4, a heat shrink tubing transfer mechanism 5, a stripping and processing mechanism 6, a welding and peeling mechanism 7, a double-sided drive mechanism 8, a double tube material box mechanism 9, and a material box storage mechanism 10. The loading and unloading mechanism 1 includes a first conveying module 101 and a first clamping module 102 set on the top of the support frame 11. The chuck is driven by the pneumatic finger 7044 cylinder to continuously clamp the conveying outer tube and the transition tube, and put them into the corresponding positioning mechanism for fixed-length cutting. For example, the first conveying module 101 includes a first linear slide module 1011 and a second linear slide module 1012, which work together with the cable chain to achieve smooth movement in the horizontal and vertical directions; Specifically, the first linear slide module 1011 is detachably mounted on the top of the support frame 11 via the first cross brace 103, and is used to horizontally move the drive chuck to a preset position; while the second linear slide module 1012 is mounted on one side of the first linear slide module 1011 via the first fixing plate 104. When picking up materials, it descends to the groove of the material box, rises to a safe height after being gripped, moves horizontally to above the positioning mechanism, and finally descends to release the pipe. Furthermore, the first clamping module 102 includes a first finger cylinder 1021, which is mounted on the outside of the first linear slide module 1011 via a first mounting plate 105. A first chuck 1022 is mounted on the end of the first finger cylinder 1021. Before clamping, photoelectric sensors and other sensors can be used to detect and confirm whether the tube is in place, ensuring that the cylinder moves to achieve stable clamping after it is in place.

[0021] Reference Figures 1-14 In this embodiment, the outer tube positioning mechanism 2 includes a second conveying module 201, a second clamping module 202, a first cutting module 203 and a first flaring module 204 disposed on one side of the middle platform 12 of the support frame 11, for length determination, cutting and flaring of the outer tube and then inserting a mandrel inside it.

[0022] For example, the second conveying module 201 includes a first motor slide module 2011, a third linear slide module 2012, and a first lead screw slide module 2013, which work in conjunction with the cable chain to achieve smooth horizontal movement. The first motor slide module 2011 and the third linear slide module 2012 are mounted in parallel on the platform 12 to drive the grippers of the second clamping module 202 to move horizontally. The first lead screw slide module 2013 is mounted on the second cross support plate 206 via a first shim 205 for horizontally moving the clamping module. Correspondingly, a second clamping module 202 is installed at one end of the first lead screw slide module 2013, which is used to clamp the outer tube and drive it to move a preset distance for fixed-length cutting; a first cutting module 203 is installed at the end of the second clamping module 202, which is used to cut one end of the outer tube; and a first flaring module 204 is installed at the other end of the first lead screw slide module 2013, which is used to flare the other end of the outer tube. Specifically, the second clamping module 202 includes a first electric gripper 2021, which is installed on one side of the first raised block 205; and a first positioning plate 2022 is installed on the top of the first electric gripper 2021 facing each other. The first positioning plate 2022 has a positioning groove on the facing side for gripping and positioning the outer tube, ensuring that the axis of the outer tube is perpendicular to the cutting blade during cutting, thereby ensuring the flatness of the cutting surface. Correspondingly, the first cutting module 203 includes a first slide cylinder 2031, which is mounted on the outside of the first positioning plate 2022 via a first vertical support plate 207; a first cutting blade holder 2032 is mounted at the end of the first slide cylinder 2031, and a first cutting blade 2033 is mounted on the outside of the first cutting blade holder 2032, so that the output end of the first slide cylinder 2031 can drive the first cutting blade holder 2032 to extend and retract, thereby driving the first cutting blade 2033 to cut the outer tube in a direction perpendicular to the outer tube axis; In addition, the first flaring module 204 includes a first core-piercing cylinder 2041, which is mounted on one side of the first lead screw slide module 2013 via a second vertical support plate 208. It is used to clamp the outer tube welding mandrel in the mandrel material box and insert it into the outer tube. Correspondingly, a second finger cylinder 2042 is provided on one side of the first core-piercing cylinder 2041, and a second chuck 2043 is installed at the end of the second finger cylinder 2042. The first mandrel material box 209 is installed on the outside of the second finger cylinder 2042, so that the second finger cylinder 2042 can drive the second chuck 2043 to clamp the outer tube mandrel. In conjunction with the guide rod of the first core-piercing cylinder 2041, the flaring and core-piercing operations of the outer tube are realized.

[0023] Reference Figures 1-14 In this embodiment, the transition tube positioning mechanism 3 includes a third conveying module 301, a third clamping module 302, a second cutting module 303, and a second flaring module 304, which are disposed in the middle of the middle platform 12 of the support frame 11, and are used for length setting, cutting and flaring the transition tube and then inserting the mandrel.

[0024] For example, the third conveying module 301 includes a second motor slide module 3011, a fourth linear slide module 3012, and a second lead screw slide module 3013, which work in conjunction with the cable chain to achieve smooth movement in the horizontal and vertical directions; wherein, the second motor slide module 3011 and the fourth linear slide module 3012 are installed in parallel on the platform 12, and the second lead screw slide module 3013 is installed on the third cross support plate 306 through the second shim 305, for horizontally moving the gripper to a preset position; Correspondingly, a third clamping module 302 is installed at one end of the second lead screw slide module 3013, which is used to clamp the transition tube and move it a preset distance for fixed-length cutting; a second cutting module 303 is installed at the end of the third clamping module 302, which is used to cut one end of the transition tube; and a second flaring module 304 is installed at the other end of the second lead screw slide module 3013, which is used to horizontally move the clamping module to flare the other end of the transition tube. Specifically, the third clamping module 302 includes a second electric gripper 3021, which is installed on one side of the second raised block 305; and a second positioning plate 3022 is installed on the top of the second electric gripper 3021. A positioning groove is provided on the opposite side of the second positioning plate 3022 for gripping the positioning transition tube, ensuring that the axis of the transition tube is perpendicular to the cutting blade during cutting, thereby ensuring the flatness of the cutting surface. Correspondingly, the second cutting module 303 includes a second slide cylinder 3031, which is mounted on the outside of the second positioning plate 3022 via a third vertical support plate 307. A second cutting blade holder 3032 is mounted at the end of the second slide cylinder 3031, and a second cutting blade 3033 is mounted on the outside of the second cutting blade holder 3032. This allows the output end of the second slide cylinder 3031 to drive the second cutting blade holder 3032 to extend and retract, thereby driving the second cutting blade 3033 to cut the transition tube in a direction perpendicular to the axis of the transition tube. In addition, the second flaring module 304 includes a second core-piercing cylinder 3041, which is mounted on one side of the second lead screw slide module 3013 via a fourth vertical support plate 308. It is used to clamp the mandrel for welding the transition tube in the mandrel material box and insert it into the transition tube. Correspondingly, a third finger cylinder 3042 is provided on one side of the second core-piercing cylinder 3041, and a third chuck 3043 is installed at the end of the third finger cylinder 3042. A second mandrel material box 309 is installed on the outside of the third finger cylinder 3042, so that the third finger cylinder 3042 can drive the third chuck 3043 to clamp the outer tube mandrel. This, together with the guide rod of the second core-piercing cylinder 3041, realizes the flaring and core-piercing operation of the transition tube.

A guide sleeve 4032 is provided at the bottom of the fourth slide cylinder 4031 for guiding the heat shrink tubing for transport. A third cutting tool holder 4033 is mounted on the outside of the fourth slide cylinder 4031, and a third cutting blade 4034 is mounted on the outside of the third cutting tool holder 4033, so that the fourth slide cylinder 4031 can drive the third cutting tool holder 4033 to move, thereby driving the third cutting blade 4034 to cut the heat shrink tubing. Furthermore, the first clamping module 404 includes a heat shrink tubing clamping block 4041, which is installed on the inner side of the tool holder support plate 4043 via a first connecting plate 4042, and can clamp the heat shrink tubing guided by the guide wheel. Furthermore, the fourth clamping module 402 includes a third slide cylinder 4021, and a fourth finger cylinder is mounted on the top of the third slide cylinder 4021 via a second fixing plate 406. A fourth chuck 4022 is mounted on the end of the fourth finger cylinder, so that the second slide cylinder 3031 can drive the fourth finger cylinder to move, thereby driving the fourth chuck 4022 to clamp the cut heat shrink tubing into the transfer station.

A fifth slide cylinder 503 is installed between the fifth linear slide module 5011 and the third lead screw slide module 5012 through a fourth shim block 502. A first positioning block 505 is installed on the top of the fifth slide cylinder 503 through a second connecting plate 504. The first positioning block 505 can be raised or lowered by the up and down movement of the fifth slide cylinder 503, so as to realize the transfer of heat shrink tubing in conjunction with the fifth linear slide module 5011 and the third lead screw slide module 5012.

[0029] Reference Figures 1-14 The stripping processing mechanism 6 includes a fifth clamping module 601 disposed between the outer tube positioning mechanism 2 and the transition tube positioning mechanism 3, which is used to clamp the heat shrink tubing and then pass through the outer tube and the transition tube with the mandrel sleeved on it. For example, the fifth clamping module 601 includes a fifth finger cylinder 6011, which is mounted on the platform 12 via a fifth cross brace 602. A stripping component 604 is mounted on the top of the fifth finger cylinder 6011 via a first lifting plate 603, and a stripping groove is provided on the top of the stripping component 604. The fifth finger cylinder 6011 drives the first lifting plate 603 to move, thereby causing the stripping component 604 to clamp the heat shrink tubing. The outer tube with the mandrel is inserted into the heat shrink tubing from one end, and the transition tube with the mandrel is inserted into the heat shrink tubing from the other end, thereby realizing the clamping of the heat shrink tubing and the stripping operation of inserting the outer tube with the mandrel and the transition tube.

[0030] Reference Figures 1-14 The welding and peeling mechanism 7 includes a sixth conveying module 701, a first guiding module 702, a first welding and cutting module 703, and a first peeling module 704, which are located on the other side of the outer tube positioning mechanism 2 and the transition tube positioning mechanism 3. These are used to guide the heat shrink tube through which the outer tube and the transition tube are inserted, weld the outer tube and the transition tube, and peel off excess material tubes.

[0031] For example, the sixth conveying module 701 includes a sixth linear slide module 7011 and a third motor slide module 7012. The sixth linear slide module 7011 and the third motor slide module 7012 are mounted in parallel on the platform 12. The top of the sixth linear slide module 7011 and the third motor slide module 7012 are equipped with a first guide module 702, a first welding and cutting module 703 and a first peeling module 704 through a sixth cross brace 705. Furthermore, the first guide module 702 includes a sixth slide cylinder 7021, which is mounted on the top side of the sixth horizontal support plate 705 via a sixth vertical support plate 706. A guide block 7023 is mounted on the outside of the sixth slide cylinder 7021 via a first connecting block 7022, so that the sixth slide cylinder 7021 can drive the first connecting block 7022 to move, thereby driving the guide block 7023 to press the heat shrink tubing and the outer tube and transition tube through which the mandrel passes. Furthermore, the first welding module includes a seventh slide cylinder 7031, which is installed at the top center of the sixth horizontal support plate 705 via a seventh vertical support plate 707. A welding block 7033 is installed on the outside of the seventh slide cylinder 7031 via a second connecting block 7032, so that the eighth slide cylinder 7041 can drive the second connecting block 7032 to move, thereby driving the welding block 7033 to weld the outer tube and transition tube inside the heat shrink tubing. After welding, the temperature can be quickly cooled to room temperature by a cooling fan to avoid deformation at the weld. Furthermore, the first peeling module 704 includes an eighth slide cylinder 7041, which is mounted on the other side of the top of the sixth horizontal support plate 705 via an eighth vertical support plate 708. Correspondingly, a sixth finger cylinder 7043 is mounted on the outside of the eighth slide cylinder 7041 via a third connecting block 7042, and a peeling block 7045 is mounted on the bottom of the sixth finger cylinder 7043 via a pneumatic finger 7044. This allows the eighth slide cylinder 7041 to drive the third connecting block 7042 to move, thereby driving the sixth finger cylinder 7043 to drive the peeling block 7045 to peel off the excess parts of the welded tube.

[0032] Reference Figures 1-14 The dual-sided drive mechanism 8 includes a seventh conveying module 801 disposed on one side of the transition tube positioning mechanism 3. The seventh conveying module 801 includes a seventh linear slide module 8011 mounted parallel to the table plate 12 for conveying the processed products.

[0033] Specifically, two parallel sets of seventh linear slide modules 8011 are rotatably connected to a geared motor module 803 via a drive shaft 802. Each set of linear slide modules has a seventh finger cylinder 805 mounted on one side via a ninth vertical support plate 804. A fifth chuck 806 is mounted at the end of the seventh finger cylinder 805, so that the seventh linear slide module 8011 can synchronously drive the seventh finger cylinder 805 under the action of the drive motor and the gear reducer, thereby driving the fifth chuck 806 to synchronously transport the processed product to the storage station.

[0034] Please continue reading. Figure 1 , Figure 2 , Figure 13 and Figure 14In this embodiment, the dual-tube material box mechanism 9 includes a first feeding box 901 and a second feeding box 902 disposed on one side of the heat shrink tubing feeding mechanism 4; wherein, the first feeding box 901 and the second feeding box 902 are mounted on the table 12 through the first support member 903, and the first feeding box 901 and the second feeding box 902 are provided with multiple layers of grooves at equal intervals for placing the outer tube and the transition tube to be processed; Correspondingly, the storage box mechanism 10 includes a feeding box 1001 disposed on one side of the double-sided drive mechanism 8, and the feeding box 1001 is mounted on the base plate; wherein, the feeding box 1001 has multiple layers of grooves at equal intervals for placing the processed products.

[0035] Working principle: The equipment operates through a PLC control system linkage mechanism to achieve fully automated welding of the balloon outer tube and the transition tube. After the equipment is started, the material box of the double tube material box mechanism 9 holds the outer tube and the transition tube to be processed. The first conveying module 101 of the loading and unloading mechanism 1 drives the first clamping module 102 to move to the double tube material box. The finger cylinder drives the chuck to clamp the outer tube and the transition tube to be processed respectively, and accurately transports them to the corresponding work positions of the outer tube positioning mechanism 2 and the transition tube positioning mechanism 3 through the horizontal and vertical slide table modules to complete the initial loading of raw materials. The second conveying module 201 of the outer tube positioning mechanism 2 drives the second clamping module 202 to clamp the outer tube and move it to a fixed length through the screw slide module. Then, the slide cylinder of the first cutting module 203 drives the cutting blade to vertically cut one end of the fixed-length outer tube. After cutting, the core-penetrating cylinder of the first flaring module 204 pushes the mandrel clamped by the second finger cylinder 2042 to penetrate into the outer tube along the axis of the outer tube. At the same time, the flaring operation of the other end of the outer tube is achieved through expansion. The third conveying module 301 and the third clamping module 302 of the transition tube positioning mechanism 3 cooperate to realize the movement of the transition tube to a fixed length. After the second cutting module 303 cuts, the second flaring module 304 inserts the mandrel into the transition tube along the axis of the transition tube. At the same time, the flaring operation of the other end of the transition tube is achieved through expansion.

[0036] The rollers of the heat shrink tubing feeding mechanism 4 stably unwind the heat shrink tubing. The heat shrink tubing is guided by the guide wheel and the guide sleeve 4032 to be transported in a straight line. The fourth clamping module 402 clamps the end of the heat shrink tubing and pulls it to the preset length through the slide module. Then, the cutting blade of the third cutting module 403 vertically cuts the heat shrink tubing. After the cutting is completed, the slide module of the heat shrink tubing transfer mechanism 5 cooperates with the cylinder to transfer the heat shrink tubing to the processing groove of the stripping part 604 of the stripping processing mechanism 6. The fifth finger cylinder 6011 of the stripping mechanism 6 drives the stripping component 604 to clamp the heat shrink tubing. The outer tube positioning mechanism 2 pushes the outer tube with the mandrel sleeve through one end of the heat shrink tubing, and the transition tube positioning mechanism 3 pushes the transition tube with the mandrel sleeve through the other end, thus cooperating to achieve the stripping treatment of the heat shrink tubing.

[0037] The guide block 7023 of the first guide module 702 on the sixth conveying module 701 of the welding peeling mechanism 7 causes the heat shrink tubing to clamp the outer tube and transition tube through which the mandrel is inserted. The heating tube of the first welding module heats and welds the connection part. After welding, it is cooled to room temperature by a cooling fan. The sixth finger cylinder 7043 of the first peeling module 704 drives the peeling block 7045 to pick up and tear off the excess material.

[0038] The two sets of synchronous slides of the double-sided drive mechanism 8 drive the seventh finger cylinder 805 to pick up the welded balloon outer tube assembly and transport it horizontally to the storage box mechanism 10. The finished product is placed into the groove of the storage box to complete the entire welding process. No manual intervention is required throughout the process. The status of each station is detected in real time by sensors to ensure the processing accuracy and product consistency.

[0039] Through the above technical solution, this application has a high degree of automation, high welding efficiency of airbag outer tube and transition tube, and the fully automated unmanned production saves a lot of labor costs. The operation process is simple, the structure is safe and reliable, and the product consistency is good.
