Description

Technical Field

[0001] This invention belongs to the field of medical accessory welding equipment and process technology, specifically relating to adaptive welding equipment and process for dissimilar metal medical accessories. Background Technology

[0002] Heterogeneous medical metal fittings refer to combinations of fittings made of different metal materials used in the medical field. Common heterogeneous metal combinations are as follows: Stainless steel and titanium alloy: Stainless steel is often used in general orthopedic fixation devices due to cost reasons, while titanium alloy is often used in high-risk implants such as cardiac stents and dental implants due to its better biocompatibility and corrosion resistance; Cobalt-chromium alloy and tantalum metal: Cobalt-chromium alloy is often used in artificial joints, while tantalum metal is often used as a filling material for bone defect repair because its elastic modulus is close to that of bone.

[0003] The advantages of dissimilar metal fittings are as follows: Material complementarity: Combinations of different metal properties can meet diverse surgical needs. For example, the lightweight and high-strength properties of titanium alloys are suitable for repairing complex bone structures, while the corrosion resistance of stainless steel is suitable for areas in contact with bodily fluids. Functional zoning: Some components are designed with dissimilar metals, such as the titanium alloy frame and stainless steel mesh structure of cardiac stents, which balances support strength and blood compatibility.

[0004] When welding surgical control panels in medical metal fittings, multiple positioning holes with the same spacing in the horizontal and vertical directions on the panel need to be drilled and welded. If only a single welding head is used in conjunction with a moving mechanism, multiple position changes are required to perform the corresponding welding action. This results in low work efficiency, a complex structural design, and inconvenient repairs once damaged. It also affects the operation of personnel and reduces the user experience. Summary of the Invention

[0005] The purpose of this invention is to provide adaptive welding equipment and process for dissimilar metal medical accessories, in order to solve the technical problem that when welding positioning holes on the panel, relying solely on a single welding head and a moving mechanism requires multiple position changes to perform the corresponding welding action, resulting in low work efficiency and affecting personnel operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Adaptive welding equipment for dissimilar metal medical accessories, including: A welding positioning mechanism includes cylinders fixed on both sides of the top of the frame. One end of the piston rod on the cylinder extends to the first slider. The first slider has a strip groove along the length of the frame, and adjacent first sliders are connected by a first swing rod. The first swing rod is polygonal in shape, and a movable shaft adapted to it is provided at the node of the first swing rod. A first welder is installed at the extended end of the bottom of the first slider. A baffle is fixedly installed on the top of the frame. One end of the baffle is connected to a movable block via a compression spring. The outer wall of the movable block has a slope, and the outer wall of the movable block moves to abut against the node on the first swing rod. The frame has an opening for connecting to the movable block. A second welder is installed on the extended end of the bottom of the movable block.

[0007] Furthermore, one end of the piston rod on the cylinder is connected to a first gear plate extending into the housing via a bent rod. The outer wall of the first gear plate is connected to a second gear plate via a central rotating tooth. The extended end of the bottom of the second gear plate passes through the frame and extends to the positioning post.

[0008] Furthermore, the first gear plate and the second gear plate are vertically staggered, the positioning column and the second slider in the fixed plate are connected by a second swing rod, the second slider is connected with a limit groove along the length direction of the fixed plate, and the second sliders are connected by a pressure roller placed above the worktable, and the outer edge of the pressure roller is provided with a rotating groove placed on the second slider.

[0009] Furthermore, both ends of the second swing rod are mounted on the positioning column and the second slider by means of a rotatable connection, and the top of the fixing plate is fixed to the frame by a vertical rod.

[0010] Furthermore, it also includes a dust collection and purification mechanism, which includes a conduit. One end of the conduit is connected to a conical air intake, and the other end is connected to a dust collection box via a pump body. Both sides of the bottom of the dust collection box are fixedly installed with drive motors. The output shaft of the drive motor passes through the dust collection box and extends to a stirring shaft inside the water tank via a reciprocating screw. A third slider is screw-driven on the reciprocating screw. Both sides of the top of the third slider are connected to a partition placed at the bottom of the water tank via fixed rods, and the bottom of the third slider and the bottom of the inner wall of the dust collection box are connected by a telescopic rod.

[0011] Furthermore, an air outlet pipe is connected above the partition and placed inside the water tank. The air outlet pipe has a telescopic structure design. The top of the stirring shaft is fixedly connected to the filter screen through a bearing, and a stirring rod is detachably installed on the outer wall of the stirring shaft. The filter screen and the partition are connected to a guide groove along the height direction of the inner wall of the water tank.

[0012] Furthermore, the filter screen has movable holes connected to the air outlet pipe, and a conical top rod corresponding to the filter holes on the filter screen is fixedly installed at the top of the inner wall of the water tank. The outer edge of the stirring shaft has an inwardly extending annular groove, and a sealing gasket connected to the partition is provided on the annular groove by adhesive fixation.

[0013] Furthermore, the top of the water tank is connected to the vent via a U-shaped pipe, and the water tank and the collection box are connected via an inclined pipe.

[0014] The adaptive welding process for dissimilar metal medical accessories includes the following steps: S1.1 Place the medical accessories on the workbench, start the cylinder and drive the first slider at multiple positions to move at equal distances, and adjust the movement distance of the first slider according to the distance between the welding holes. S1.2 During the rotational connection process, the first swing rod, through its contact with the moving block, causes the moving block to adjust its movement distance in the vertical direction of the horizontal plane according to the contact distance, and the first welder and the second welder perform welding work at the corresponding welding holes. S1.3 During the welding process, the pump starts, which can draw the fumes into the water tank. The drive motor starts, so that the fumes in the bubbles can fully contact the water under the action of the stirring rod. With the help of the filter screen, the precipitated impurities enter the collection box through the baffle and the inclined pipe.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, when welding and drilling multiple positioning holes on a medical control panel, the cylinder is started and drives the first sliders at both ends to move in the center. Under the rotational connection of the first swing rod, the distance between the outer first sliders can be adjusted synchronously at the same distance. Moreover, during the movement of the first slider, the first swing rod and the slope on the moving block make active contact. With the elasticity of the compression spring itself, the moving block can move synchronously in the vertical direction of the horizontal plane. The first welder on the first slider and the second welder on the moving block can adapt to the welding work of positioning holes with different equidistant size changes in the horizontal direction of the horizontal plane, and can also adapt to the welding work of positioning holes with corresponding equidistant changes in the vertical direction of the horizontal plane. It has strong application performance and high work efficiency.

[0016] (2) In this invention, when the first slider moves in the center under the push of the cylinder, it can synchronously drive the first gear plate to move. Under the action of gear meshing transmission, it can not only transmit the force to the positioning column, but also convert the horizontal force into the vertical force, so that the positioning column moves down to the medical accessory to achieve positioning and clamping work, and prevent the position deviation from occurring during the welding process. In addition, under the rotational connection of the second swing rod, the pressure roller achieves the rolling pressing effect on the medical accessory. Through the rolling pressing method, the accessory is further positioned and clamped, thereby improving the stability and safety of the equipment operation.

[0017] (3) In this invention, the fumes generated during the welding process can enter the dust collection box through the conical air intake connected to the pump body. The fumes come into contact with the water and are filtered and purified. In order to eliminate the fumes contained in the bubbles, the drive motor is started and drives the reciprocating screw and the stirring shaft to rotate synchronously. During the rotation of the reciprocating screw, under the action of the screw drive, the partition moves up and down through the fixed rod. Due to the inclined setting of the partition, the precipitated impurities will fall into the collection box through the inclined pipe. The stirring shaft is provided with an inwardly extending annular groove, which not only ensures the free rotation of the stirring rod, but also stably transmits the vertical force to the stirring rod so that it can move freely. In addition, the setting of the stirring rod on the stirring shaft, together with the filter screen and the air outlet pipe with the telescopic structure design inside the water tank, can ensure the free movement of the transmission components, and can further remove the impurity particles that may be contained in the bubbles under the action of stirring and screening. The stirring rod can stir at different heights at the air outlet, so that the fumes and dust particles can be effectively separated from the gas, improving the purification quality and benefiting the environment.

[0018] (4) In this invention, the entire welding process is highly automated, and the positioning holes of different equidistant sizes can be adjusted adaptively, which speeds up the work efficiency, reduces manpower, and can also effectively purify the fumes generated during the welding process, ensuring air quality and processing environment. The design is reasonable and the integrated performance is strong. Attached Figure Description

[0022] 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.

[0023] Reference manual attached Figure 1 - Appendix Figure 9 As shown, the adaptive welding equipment for dissimilar metal medical accessories includes: Welding positioning mechanism 1 includes cylinders 2 fixed on both sides of the top of frame 4. One end of the piston rod on cylinder 2 extends to the first slider 3. The first slider 3 has a strip groove along the length of frame 4, and adjacent first sliders 3 are connected by a first swing rod 5. The first swing rod 5 is polygonal in shape, and a movable shaft adapted to it is provided at the node of the first swing rod 5. A first welder 6 is installed at the extended end of the bottom of the first slider 3. A baffle 7 is fixedly installed on the top of the frame 4. One end of the baffle 7 is connected to a movable block 9 via a compression spring 8. The outer wall of the movable block 9 has a slope, and the outer wall of the movable block 9 moves against the node on the first swing rod 5. The frame 4 has an opening for connecting to the movable block 9. A second welder 10 is installed on the extended end of the bottom of the movable block 9.

[0024] When performing welding and drilling operations on multiple positioning holes on a medical control panel, cylinder 2 is activated and drives the first sliders 3 at both ends to move in a centered manner. Under the rotational connection of the first swing rod 5, the distance between the outer first sliders 3 can be adjusted synchronously at the same distance. Moreover, during the movement of the first sliders 3, the first swing rod 5 and the slope on the moving block 9 make active contact. With the elasticity of the compression spring 8, the moving block 9 can move synchronously as a whole in the vertical direction of the horizontal plane. The first welder 6 on the first slider 3 and the second welder 10 on the moving block 9 can adapt to the welding work of positioning holes with different equidistant sizes in the horizontal direction of movement, and can also adapt to the welding work of positioning holes with corresponding equidistant changes in the vertical direction of the horizontal plane. It has strong application performance and high work efficiency.

[0025] During the start-up process of the cylinders 2 on both sides of the frame 4, the first sliders 3 on the outer side move synchronously to center. During the centering movement, the distance between the first welders 6 is not only adjusted synchronously and equidistantly to adapt to the positioning holes in the horizontal direction, but the first swing rod 5 also remains in an extended position during the centering movement. That is to say, the outward movement distance of the first swing rod 5 increases. During the movement and contact process, it can synchronously drive the moving block 9 to move towards the baffle 7, thereby allowing the multiple second welders 10 on the frame 4 to be synchronously adjusted in the vertical direction of the horizontal plane. That is, the distance between the corresponding positioning holes on the second welders 10 and the positioning holes on the first welders 6 is synchronously adjusted.

[0026] Specifically, one end of the piston rod on the cylinder 2 is connected to a first gear plate 11 extending into the housing 38 via a bent rod. The outer wall of the first gear plate 11 is connected to a second gear plate 13 via a central rotating tooth 12. The extended end of the bottom of the second gear plate 13 passes through the frame 4 and extends to the positioning post 14.

[0027] During startup, cylinder 2 can synchronously drive the first gear plate 11 to move. As the first gear plate 11 moves to the right, it can not only drive the central rotating tooth 12 to rotate, but also drive the second gear plate 13 to move downward, thereby playing a positioning and clamping role as the positioning pin 14 moves downward.

[0028] The first gear plate 11 and the second gear plate 13 are vertically staggered. The positioning post 14 and the second slider 16 in the fixed plate 15 are connected by the second swing rod 17. The second slider 16 is connected with a limit groove along the length of the fixed plate 15, and the second sliders 16 are connected by a pressure roller 18 placed above the worktable. The outer edge of the pressure roller 18 is provided with a rotating groove placed on the second slider 16. The above-mentioned vertically staggered structure of the first gear plate 11 and the second gear plate 13 avoids interference between the transmission components during the movement and ensures the safety of the movement of the transmission components, so that the force can be transmitted stably.

[0029] In addition, both ends of the second swing rod 17 are mounted on the positioning column 14 and the second slider 16 by means of rotational connection. The top of the fixed plate 15 is fixed to the frame 4 by a vertical rod. Under the rotational connection of the second swing rod 17, the second slider 16 moves horizontally in the fixed plate 15, which allows the pressure roller 18 to roll and press, thereby further ensuring the flatness and positioning effect of the panel.

[0030] The adaptive welding equipment for dissimilar metal medical accessories also includes a dust collection and purification mechanism 19. The dust collection and purification mechanism 19 includes a conduit 20, one end of which is connected to a conical air intake port, and the other end is connected to a dust collection box 21 via a pump body. Both sides of the bottom of the dust collection box 21 are fixedly installed with drive motors 22. The output shaft of the drive motor 22 passes through the dust collection box 21 and extends through a reciprocating screw 23 to a stirring shaft 25 inside the water tank 24. A third slider 26 is screw-driven on the reciprocating screw 23. Both sides of the top of the third slider 26 are connected to a partition 28 placed at the bottom of the water tank 24 via a fixing rod 27. The bottom of the third slider 26 and the bottom of the inner wall of the dust collection box 21 are connected by a telescopic rod 29.

[0031] When the first slider 3 moves in the center under the push of the cylinder 2, it can synchronously drive the first gear plate 11 to move. Under the action of gear meshing transmission, it can not only transmit the force to the positioning column 14, but also convert the horizontal force into the vertical force, so that the positioning column 14 moves downward to the medical accessory to achieve positioning and clamping work, preventing the position deviation from occurring during the welding process. In addition, under the rotational connection of the second swing rod 17, the pressure roller 18 achieves rolling pressing on the medical accessory. Through rolling pressing, the accessory is further positioned and clamped, improving the stability and safety of the equipment operation.

[0032] Above the partition 28 is an air outlet pipe 30 placed inside the water tank 24. The air outlet pipe 30 has a telescopic structure design. The top of the stirring shaft 25 is fixedly connected to the filter screen 32 through the bearing 31. The stirring rod 33 is detachably installed on the outer wall of the stirring shaft 25. The filter screen 32 and the partition 28 are connected to the guide groove along the height direction of the inner wall of the water tank 24.

[0033] The fumes generated during welding can enter the dust collection box 21 through the conical suction port connected to the pump body. The fumes come into contact with and are filtered and purified by the water. To eliminate the fumes particles contained in the bubbles, the drive motor 22 is started, driving the reciprocating screw 23 and the stirring shaft 25 to rotate synchronously. During the rotation of the reciprocating screw 23, under the action of screw transmission, the fixed rod 27 drives the partition 28 to move up and down. Due to the inclined setting of the partition 28, the precipitated impurities will fall into the collection box 36 through the inclined pipe 37. The stirring shaft 25 is provided with an inwardly extending annular groove, which not only ensures the free movement of the stirring rod 33, but also... Rotation also allows the vertical force to be stably transmitted to the stirring rod 33, enabling it to move freely. Furthermore, the arrangement of the stirring rod 33 on the stirring shaft 25, in conjunction with the filter screen 32 and the telescopic structure of the air outlet pipe 30 inside the water tank 24, ensures the free movement of the transmission components. It also further removes any impurities that may be present in the air bubbles through stirring and screening. The stirring rod 33 can stir and process air bubbles at different heights at the air outlet, thereby breaking them up and effectively separating dust particles from the gas, improving the purification quality and benefiting environmental protection.

[0034] Specifically, the filter screen 32 has a movable hole that connects to the air outlet pipe 30. A conical top rod 34 corresponding to the filter holes on the filter screen 32 is fixedly installed on the top of the inner wall of the water tank 24. The outer edge of the stirring shaft 25 has an inwardly extending annular groove. A sealing gasket connected to the partition plate 28 is provided on the annular groove by adhesive fixation. The sealing gasket can ensure the sealing of the connection between the stirring shaft 25 and the partition plate 28 during the movement. The top of the water tank 24 is connected to the exhaust port 35 through a U-shaped pipe. The water tank 24 and the collection box 36 are connected by an inclined pipe 37. The conical top rod 34 can remove the impurities blocked on the filter screen 32, thereby ensuring the corresponding cleaning effect.

[0035] Furthermore, the stirring shaft 25 near the partition 28 not only has an inwardly arranged annular groove, but also has a telescopic structure design at the partition 28. This allows the stirring shaft 25 to move freely up and down during the rise of the partition 28, and also allows the stirring shaft 25 to rotate freely at the partition 28. The aforementioned telescopic structure design of the stirring shaft 25 is a conventional technical means for those skilled in the art, namely a telescopic sleeve combined with a concave groove with a protrusion. Although there are no corresponding drawings, it does not affect the effective implementation of the technical solution of the present invention.

[0036] In addition, in conjunction with the instruction manual Figure 9 It is known that the outer wall of the partition 28 has through holes, which, together with the telescopic side plates 39 on both sides of the third slider 26, not only provide corresponding sealing protection for the transmission components of the drive motor 22, but also allow the partition 28 to move up and down normally. During the upward movement of the partition 28, the volume of the sealed cavity between the telescopic side plate 39 and the dust collection box 21 increases, and the volume of water increases, which causes the partition 28 to carry the settled impurities into the collection box 36, while not bringing water into the collection box 36, thus effectively separating the two.

[0037] Reference manual attached Figure 10 The adaptive welding process for dissimilar metal medical accessories includes the following steps: S1.1 Place the medical accessories on the workbench, start the cylinder 2 and drive the first slider 3 at multiple positions to move at equal distances, and make adaptive adjustments to the movement distance of the first slider 3 according to the distance between the welding holes. S1.2 During the rotational connection process, the first swing rod 5, through its contact with the moving block 9, causes the moving block 9 to adjust its movement distance in the vertical direction of the horizontal plane according to the contact distance, and the first welder 6 and the second welder 10 perform welding work at the corresponding welding holes. S1.3 During the welding process, the pump is started, which can draw the fumes into the water tank 24. The drive motor 22 is started, so that the fumes in the bubbles can fully contact the water under the action of the stirring rod 33. With the help of the filter screen 32, the precipitated impurities enter the collection box 36 through the baffle 28 and the inclined pipe 37.

[0038] The entire welding process is highly automated, capable of adaptively adjusting the position of positioning holes of different equidistant sizes, which speeds up work efficiency, reduces manpower, and effectively purifies the fumes generated during the welding process, ensuring air quality and processing environment. It has a reasonable design and strong integrated performance.
