Description

Technical Field

[0001] This invention relates to the field of staple cartridge welding technology, specifically a welding device for the production of staple cartridges with polishing function. Background Technology

[0002] As an important surgical instrument, the reliability and safety of a stapler are directly determined by the welding quality of its core components, the staple cartridge seat and the anvil seat. These two components are typically made of high-hardness, high-precision stainless steel or special alloys, and the welding between them falls into the category of micro-precision welding. Currently, several key technical bottlenecks still exist in the production and welding process of these components, severely restricting product quality and production efficiency. These bottlenecks are specifically reflected in the following three aspects:

[0003] The assembly positional precision requirements for the staple cartridge and anvil are extremely high, typically needing to be controlled at the micrometer level. Traditional methods often rely on high-precision fixtures for physical positioning, or on manual fine-tuning by operators under a microscope before welding. The former places extremely high demands on the machining and maintenance of the fixtures, as any minute deformation or wear can lead to batch-to-batch deviations; the latter is inefficient, relies on manual experience, and makes it difficult to guarantee consistency.

[0004] To improve weld quality, increase penetration and width, and reduce defects such as porosity, oscillating welding (where the welding torch oscillates laterally and periodically along the weld seam) has become a preferred process. However, in the micro-welding application of pin holders and anvils, traditional oscillating welding mechanisms are generally linear welding. In reality, the oscillation frequency, amplitude, welding speed, and current in oscillating welding are mostly controlled independently in an open loop, making it difficult to achieve dynamic coordination.

[0005] To meet the biocompatibility and functional requirements of medical devices, the weld area must be polished and deburred after welding to reduce surface roughness and eliminate micro-stress concentration points. Currently, the standard process treats welding and polishing as two separate steps. The workpiece needs to be unloaded from the welding station, transported, and re-clamped on the polishing equipment. This not only increases the production cycle time but also introduces new positioning errors during the secondary clamping, potentially causing the polished area to misalign with the weld area. Summary of the Invention

[0006] The purpose of this invention is to provide a welding apparatus for the production of stapler cartridge seats with polishing function, so as to solve the problems mentioned in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0013] Furthermore, the first centering component includes a first movable frame, a rotary motor, a first electric push rod, a pull rod, a telescopic cylinder, a fixed cylinder, and a photoresistor. The first movable frame is fixedly connected to the telescopic end of the double-headed electric telescopic rod. The first movable frame provides an installation base for the rotary motor. The output end of the rotary motor is fixedly connected to the fixed cylinder. The fixed end of the first electric push rod is fixedly installed on the first movable frame. One end of the pull rod is fixedly connected to the telescopic end of the first electric push rod, and the other end of the pull rod is fixedly connected to the telescopic end of the telescopic cylinder. The fixed end of the telescopic cylinder is fixedly connected to the fixed end of the rotary motor. The fixed cylinder is located inside the telescopic cylinder, and a photoresistor is provided on the outer surface of the fixed cylinder.

[0014] Furthermore, the first centering assembly also includes a clamping block and a second spring-driven electric push rod. The clamping block is slidably installed inside the fixed cylinder and is used to clamp and fix the anvil. The fixed end of the second spring-driven electric push rod is fixedly installed inside the fixed cylinder, and the telescopic end of the second spring-driven electric push rod is fixedly connected to the clamping block. The telescopic end of the first electric push rod is fixedly connected to the moving ring, and the moving ring has a through hole.

[0015] Furthermore, the second centering assembly includes a second movable frame, a straight cylinder, a stop block, a third spring-driven electric push rod, a conductive sheet, a conductive block, and a return spring. The second movable frame is fixedly connected to the telescopic end of the double-headed electric telescopic rod. The straight cylinder is fixedly installed on the second movable frame. The stop block is slidably installed inside the straight cylinder. The stop block is connected to the conductive sheet via the third spring-driven electric push rod. The conductive sheet is slidably installed inside the straight cylinder. The conductive block is fixedly installed inside the straight cylinder. A return spring is provided between the stop block and the conductive sheet. The conductive block is electrically connected to the first electric push rod. The stop block is provided with an arc-shaped clamping hole adapted to the staple cartridge seat.

[0016] Furthermore, the polishing unit includes a crossbar, a bent bar, a polishing wheel, and a connecting plate. The crossbar is fixedly installed at the through hole on the moving ring.

The rotating end of the micro motor is fixedly connected to the polishing wheel. The bent bar is fixedly connected to the connecting plate, and the connecting plate is connected to the moving ring through a memory spring.

[0017] Furthermore, the welding unit includes a transverse component, a longitudinal component, a connecting block, a hydraulic push rod, and a welding head.

[0018] Furthermore, a ranging element is provided inside the moving ring.

[0019] Furthermore, the second spring electric actuator and the third spring electric actuator are alternately supplied with current.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention involves the operator placing the anvil into the clamping block and the staple cartridge seat onto the anvil. The controller then retracts the double-headed electric telescopic rod, causing the first and second moving frames to move closer together, bringing the staple cartridge seat and the anvil into contact. As the second moving frame moves, the staple cartridge seat pushes the anvil, causing the conductive plate to contact the conductive block and compress the return spring. This allows the controller's current to be transmitted to the first electric push rod through the conductive plate and block. The first electric push rod then extends, moving the moving ring forward to the welding point between the anvil and the staple cartridge seat and stopping. Simultaneously, under the action of the pull rod, the telescopic cylinder extends to block the fixed cylinder. The photoresistor detects a decrease in light intensity, causing the controller to detect an increase in resistance in the circuit. When the resistance reaches a set value, the controller sends a timed current to the electromagnet ring and the electric spring push rod. Upon receiving the current, the electromagnet ring exhibits the same polarity as the magnetic ring, thus pushing the magnetic ring forward. Simultaneously, the electric spring push rod pushes the alignment block inward to align the weld between the pin seat and the pin cartridge seat, preventing misalignment and affecting weld quality. When the timed current from the controller ends, the electromagnet ring loses power and no longer exhibits polarity. Under the action of the spring, the magnetic ring resets, and the electric spring push rod, after losing power, moves the alignment block away from the weld joint due to its own restoring force.

[0022] 2. After alignment is completed, the controller starts the rotary motor, which drives the clamping block in the fixed cylinder to rotate synchronously, thereby driving the anvil and the nail cartridge seat to rotate synchronously. At the same time, the controller controls the second spring electric push rod and the third spring electric push rod to extend and retract alternately. When the second spring electric push rod extends, the third spring electric push rod retracts, causing the anvil and the nail cartridge seat to reciprocate. As the welding head welds the weld joint, oscillating welding is achieved, thereby improving the penetration and width of the weld, reducing defects such as porosity, and improving the welding quality.

[0023] 3. In this invention, the ranging element detects a change in the position of the magnetic ring and sends a signal to the controller. The controller then sends current to the memory spring, which contracts and pulls the connecting plate, thereby causing the bent rod to deflect the polishing wheel outward. This completes the action of the polishing wheel avoiding the alignment block. After the magnetic ring is reset, the memory spring, under its own restoring force, drives the polishing wheel to reset. The micro motor drives the polishing wheel to rotate, thereby polishing the weld. Attached Figure Description

[0036] 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.

[0037] Example: Figures 1-11 As shown, the present invention provides a technical solution:

[0038] like Figure 1 , Figure 5 , Figure 7 As shown, the welding device includes a worktable 1, a controller is installed on the worktable 1, a vibrating plate is installed on the worktable 1, and a centering unit 2 is installed on the worktable 1. The centering unit 2 includes a split clamping structure and an adjustment component.

[0039] The segmented clamping structure includes an electric spring push rod 223 and an alignment block 224, with the telescopic end of the electric spring push rod 223 fixedly connected to the alignment block 224.

[0040] The adjustment assembly includes a moving ring 220, an electromagnet ring 221, and a magnetic ring 222. The electromagnet ring 221 is fixedly installed inside the moving ring 220, and the magnetic ring 222 is slidably installed inside the moving ring 220. The fixed end of the electric spring push rod 223 is fixedly installed inside the magnetic ring 222. The electromagnet ring 221 and the magnetic ring 222 are connected by a spring.

[0041] The centering unit 2 is equipped with a polishing unit 3, and the welding unit 4 is set on the worktable 1.

[0042] Workbench 1 provides the mounting base, centering unit 2 ensures the alignment of the staple cartridge seat and the anvil seat before welding, polishing unit 3 polishes the weld seam during the welding process, and welding unit 4 welds the staple cartridge seat and the anvil seat. After the staple cartridge seat and the anvil seat to be welded are clamped and placed on centering unit 2, they are aligned by centering unit 2 to avoid misalignment affecting the welding quality. After alignment is completed, welding unit 4 welds the weld joint while polishing unit 3 polishes the weld joint to improve the appearance quality of the weld joint.

[0043] like Figure 2 , Figure 6 As shown, the centering unit 2 includes a first centering component 21, a second centering component 22, and a double-headed electric telescopic rod 23. The first centering component 21 and the second centering component 22 are respectively fixedly connected to the telescopic ends of the double-headed electric telescopic rod 23. The fixed end of the double-headed electric telescopic rod 23 is fixedly installed on the workbench 1.

[0044] like Figure 3 , Figure 4As shown, the first centering component 21 includes a first movable frame 211, a rotary motor 212, a first electric push rod 213, a pull rod 214, a telescopic cylinder 215, a fixed cylinder 216, and a photoresistor 217. The first movable frame 211 is fixedly connected to the telescopic end of the double-headed electric telescopic rod 23. The first movable frame 211 provides an installation base for the rotary motor 212. The output end of the rotary motor 212 is fixedly connected to the fixed cylinder 216. The fixed end of the first electric push rod 213 is fixedly installed on the first movable frame 211. One end of the pull rod 214 is fixedly connected to the telescopic end of the first electric push rod 213, and the other end of the pull rod 214 is fixedly connected to the telescopic end of the telescopic cylinder 215. The fixed end of the telescopic cylinder 215 is fixedly connected to the fixed end of the rotary motor 212. The fixed cylinder 216 is located inside the telescopic cylinder 215, and a photoresistor 217 is provided on the outer surface of the fixed cylinder 216.

[0045] like Figure 3 , Figure 4 As shown, the first centering component 21 also includes a clamping block 218 and a second spring electric push rod 219. The clamping block 218 is slidably installed in the fixed cylinder 216 and is used to clamp the fixed anvil. The fixed end of the second spring electric push rod 219 is fixedly installed in the fixed cylinder 216, and the telescopic end of the second spring electric push rod 219 is fixedly connected to the clamping block 218. The telescopic end of the first electric push rod 213 is fixedly connected to the moving ring 220, and the moving ring 220 has a through hole.

[0046] like Figure 6 , Figure 8 As shown, the second centering assembly 22 includes a second movable frame 24, a straight cylinder 25, a stop block 26, a third spring-driven electric push rod 27, a conductive sheet 28, a conductive block 29, and a return spring 210. The second movable frame 24 is fixedly connected to the telescopic end of the double-headed electric telescopic rod 23. The straight cylinder 25 is fixedly installed on the second movable frame 24. The stop block 26 is slidably installed inside the straight cylinder 25. The straight cylinder 25 is connected to the conductive sheet 28 through the third spring-driven electric push rod 27. The conductive sheet 28 is slidably installed inside the straight cylinder 25. The conductive block 29 is fixedly installed inside the straight cylinder 25. A return spring 210 is provided between the stop block 26 and the conductive sheet 28. The conductive block 29 is electrically connected to the first electric push rod 213. The stop block 26 is provided with an arc-shaped clamping hole adapted to the nail cartridge seat.

[0047] After the worker places the anvil into the clamping block 218 and the staple cartridge seat onto the anvil 26, the controller controls the double-headed electric telescopic rod 23 to retract, thereby causing the first moving frame 211 and the second moving frame 24 to move closer to each other, so that the staple cartridge seat and the anvil are in contact at the weld. Subsequently, as the second moving frame 24 moves, the staple cartridge seat pushes the anvil 26, causing the conductive plate 28 to contact the conductive block 29 and compress the return spring 210, so that the current of the controller is transmitted to the first electric push rod 213 through the conductive plate 28 and the conductive block 29. At this time, the first electric push rod 213 is energized and extends, on the one hand, it drives the moving ring 220 forward to the weld between the anvil and the staple cartridge seat and stops, and on the other hand, under the action of the pull rod 214, it drives the telescopic cylinder 215 to extend and block the fixed cylinder 216. When the photoresistor 217 detects a decrease in light intensity, the controller detects an increase in resistance in the circuit reaching a set value. The controller then supplies a timing current to the electromagnet ring 221 and the electric spring push rod 223. Upon receiving the current, the electromagnet ring 221 exhibits the same polarity as the magnetic ring 222, thus pushing the magnetic ring 222 forward. Simultaneously, the electric spring push rod 223 pushes the alignment block 224 inward to align the weld between the pin holder and the pin cartridge, preventing misalignment and ensuring welding quality. When the timing current supplied by the controller ends, the electromagnet ring 221 loses power and no longer exhibits polarity. Under the action of the spring, the magnetic ring 222 resets, and the electric spring push rod 223, after losing power, moves the alignment block 224 away from the weld joint under its own restoring force.

[0048] like Figure 9 , Figure 10 As shown, the polishing unit 3 includes a crossbar 31, a bent bar 32, a polishing wheel 33, and a connecting plate 34. The crossbar 31 is fixedly installed at the through hole on the moving ring 220. One end of the bent bar 32 is rotatably installed on the crossbar 31, and the other end of the bent bar 32 is fixedly connected to the fixed end of the micro motor. The rotating end of the micro motor is fixedly connected to the polishing wheel 33. The bent bar 32 is fixedly connected to the connecting plate 34, and the connecting plate 34 is connected to the moving ring 220 through a memory spring.

[0049] When the ranging element detects a change in the position of the magnetic ring 222, it sends a signal to the controller. The controller then sends current to the memory spring, which contracts and pulls the connecting plate 34. This causes the bent rod 32 to drive the polishing wheel 33 to deflect outward, thus completing the action of the polishing wheel 33 avoiding the alignment block 224. After the magnetic ring 222 is reset, the memory spring drives the polishing wheel 33 to reset under its own restoring force. The micro motor drives the polishing wheel 33 to rotate, thereby polishing the weld.

[0050] like Figure 11As shown, the welding unit 4 includes a transverse component 41, a longitudinal component 42, a connecting block 43, a hydraulic push rod 44, and a welding head 45. The transverse component 41 is fixedly connected to the worktable 1. The longitudinal component 42 is slidably mounted on the transverse component 41. The connecting block 43 is fixedly connected to the longitudinal component 42. The fixed end of the hydraulic push rod 44 is fixedly mounted on the connecting block 43. The telescopic end of the hydraulic push rod 44 is fixedly connected to the welding head 45. Both the transverse component 41 and the longitudinal component 42 are driven by a drive component.

[0051] The controller controls the drive assembly to move the transverse component 41 and the longitudinal component 42 to move the connecting block 43 until the welding head 45 is directly above the welding point of the anvil and the staple cartridge. At this time, the controller controls the hydraulic push rod 44 to start, thereby driving the welding head 45 to descend and perform welding.

[0052] like Figure 3 As shown, a ranging element is installed inside the moving ring 220.

[0053] The ranging element can be a distance sensor, displacement sensor or other ranging sensor, used to detect changes in the position of the magnetic ring 222, and then feed back a signal to the controller, which controls the polishing unit 3 to move and avoid the centering action of the centering unit 2.

[0054] like Figure 4 , Figure 8 As shown, the second spring electric push rod 219 and the third spring electric push rod 27 are alternately supplied with current.

[0055] After alignment is completed, the controller starts the rotary motor 212, which drives the clamping block 218 in the fixed cylinder 216 to rotate synchronously, thereby driving the anvil and the nail cartridge seat to rotate synchronously. At the same time, the controller controls the second spring electric push rod 219 and the third spring electric push rod 27 to extend and retract alternately. When the second spring electric push rod 219 extends, the third spring electric push rod 27 retracts, causing the anvil and the nail cartridge seat to reciprocate. As the welding head 45 welds the weld joint, oscillating welding is achieved, thereby improving the penetration and width of the weld, reducing defects such as porosity, and improving the welding quality.

[0056] Working principle of the invention:

[0057] After the worker places the anvil into the clamping block 218 and the staple cartridge seat onto the anvil 26, the controller controls the double-headed electric telescopic rod 23 to retract, thereby causing the first moving frame 211 and the second moving frame 24 to move closer to each other, so that the staple cartridge seat and the anvil are in contact at the weld. Subsequently, as the second moving frame 24 moves, the staple cartridge seat pushes the anvil 26, causing the conductive plate 28 to contact the conductive block 29 and compress the return spring 210, so that the current of the controller is transmitted to the first electric push rod 213 through the conductive plate 28 and the conductive block 29. At this time, the first electric push rod 213 is energized and extends, on the one hand, it drives the moving ring 220 forward to the weld between the anvil and the staple cartridge seat and stops, and on the other hand, under the action of the pull rod 214, it drives the telescopic cylinder 215 to extend and block the fixed cylinder 216. When the photoresistor 217 detects a decrease in light intensity, the controller detects an increase in resistance in the circuit reaching a set value. The controller then supplies a timing current to the electromagnet ring 221 and the electric spring push rod 223. Upon receiving the current, the electromagnet ring 221 exhibits the same polarity as the magnetic ring 222, thus pushing the magnetic ring 222 forward. Simultaneously, the electric spring push rod 223 pushes the alignment block 224 inward to align the weld between the pin holder and the pin cartridge, preventing misalignment and ensuring welding quality. When the timing current supplied by the controller ends, the electromagnet ring 221 loses power and no longer exhibits polarity. Under the action of the spring, the magnetic ring 222 resets, and the electric spring push rod 223, after losing power, moves the alignment block 224 away from the weld joint under its own restoring force.

[0058] After alignment is completed, the controller starts the rotary motor 212, which drives the clamping block 218 in the fixed cylinder 216 to rotate synchronously, thereby driving the anvil and the nail cartridge seat to rotate synchronously. At the same time, the controller controls the second spring electric push rod 219 and the third spring electric push rod 27 to extend and retract alternately. When the second spring electric push rod 219 extends, the third spring electric push rod 27 retracts, causing the anvil and the nail cartridge seat to reciprocate. As the welding head 45 welds the weld joint, oscillating welding is achieved, thereby improving the penetration and width of the weld, reducing defects such as porosity, and improving the welding quality.

[0059] When the ranging element detects a change in the position of the magnetic ring 222, it sends a signal to the controller. The controller then sends current to the memory spring, which contracts and pulls the connecting plate 34. This causes the bent rod 32 to drive the polishing wheel 33 to deflect outward, thus completing the action of the polishing wheel 33 avoiding the alignment block 224. After the magnetic ring 222 is reset, the memory spring drives the polishing wheel 33 to reset under its own restoring force. The micro motor drives the polishing wheel 33 to rotate, thereby polishing the weld.

[0060] The controller controls the drive assembly to move the transverse component 41 and the longitudinal component 42 to move the connecting block 43 until the welding head 45 is directly above the welding point of the anvil and the staple cartridge. At this time, the controller controls the hydraulic push rod 44 to start, thereby driving the welding head 45 to descend and perform welding.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
