Description

Technical Field

[0001] The present invention relates to the technical field of anvil assembly welding, and in particular to welding equipment and a welding method for anvil assembly production. Background Art

[0002] The anvil assembly plays an important role in the field of medical devices, especially in surgical operations, where its role is mainly reflected in positioning and fixation. The anvil assembly, through its design structure, can accurately position and fix surgical instruments during the operation, ensuring the accuracy and stability of the surgical operation. For example, in circumcision and anastomosis surgery, the anvil assembly, through its specific structure and design, can be accurately placed at the site requiring surgery, providing a stable operating platform for the operation. It has the advantages of fast suturing, simple operation, and few side effects and surgical complications. The anvil assembly mainly consists of an anvil, a connecting mechanism, a limiting fixing mechanism, and a connecting shaft. During production, the anvil assembly requires the use of laser welding equipment to weld the connecting shaft to the anvil.

[0003] Currently, during the welding process of the anvil assembly, it is necessary to fit the bottom surface of the connecting shaft with the surface of the anvil, and the centers of the connecting shaft and the anvil are located on the same center line to improve the welding accuracy of the anvil. Currently, when welding the anvil and the connecting shaft, due to the small size of the anvil and the connecting shaft, the welding and positioning of each anvil assembly is time-consuming and labor-intensive, which increases the time required for welding and greatly affects the efficiency of welding. In addition, during the welding process, the lower end of the connecting shaft is easily affected by the external force generated by the vibration of the equipment and cannot be tightly fitted on the anvil, resulting in the problem of cold welding during welding, which greatly affects the quality of product processing. Summary of the Invention

[0004] The present invention provides a welding device and a welding method for producing an anvil assembly, which has the advantages of saving time and labor during the welding positioning process of the workpiece, being convenient and quick, and at the same time, the connecting shaft is not easily affected by external forces during the welding process, which can improve the welding quality and welding accuracy. It solves the problem mentioned in the above background technology that when the anvil and the connecting shaft are currently welded, due to the small size of the anvil and the connecting shaft, each anvil assembly is more time-consuming and labor-intensive during the welding positioning process, which increases the time required for welding and greatly affects the welding efficiency. In addition, during the welding process, the lower end of the connecting shaft is easily affected by the external force generated by the vibration of the equipment and cannot be tightly fitted on the anvil, resulting in the problem of cold welding during welding, which greatly affects the quality of product processing.

[0011] As an alternative solution for the welding equipment used in the production of the anvil component of the present invention, wherein: above the welding seat, there is a C-shaped block, on which a third sliding rod is fixed. The third sliding rod is elastically connected to the vertical rod through a fourth spring. Inside the C-shaped block, two fourth sliding rods are fixed.

[0012] As an alternative solution for the welding equipment used in the production of the anvil component of the present invention, wherein: below the cleaning bracket, there is a second abutting wedge block. The second abutting wedge block is elastically connected to the second abutting wedge block through a sixth spring.

[0013] As an alternative solution for the welding equipment used in the production of the anvil component of the present invention, wherein: on the welding seat, a fifth sliding rod is fixed. A hollow rectangular rod is slidably connected to the fifth sliding rod. The hollow rectangular rod is elastically connected to the welding seat through a seventh spring. And one end of the hollow rectangular rod abuts against the placement seat. A nozzle is fixed on the hollow rectangular rod.

[0014] As an alternative solution for the welding equipment used in the production of the anvil component of the present invention, wherein: on the cleaning bracket, a sliding bracket is fixed. One end of the cleaning block is provided with a scraping bracket. The upper end of the scraping bracket is elastically connected to the sliding bracket through an eighth spring. A third abutting wedge block is fixed on the scraping bracket. A resisting strip is fixed on the mounting bracket.

[0015] The welding method of the welding equipment for the production of the anvil component includes the following specific steps:

[0016] Step 1, workpiece feeding. Place the anvil body into the placement seat. Push the rotating component horizontally through the first electric push rod, and push the placement seat into the card slot in the welding seat to position the anvil body. Clamp the connecting shaft with two first arc-shaped clamping blocks arranged on the electric claw. Push the vertical rod horizontally through the second electric push rod. When the connecting shaft coincides with the center of the anvil body, the limiting block fixed on the vertical rod abuts against the welding seat, then the vertical rod stops moving. The servo electric cylinder fixed on the vertical rod drives the support plate to move downward, so that the lower end of the connecting shaft tightly abuts against the surface of the anvil body.

[0017] Step 2, workpiece positioning. The end of the second electric push rod continues to move to push the C-shaped abutting frame horizontally, causing the C-shaped abutting frame to abut against the first abutting wedges fixed below the two mounting brackets. The two mounting brackets drive the second arc-shaped clamping blocks to move horizontally and abut against the surface of the connecting shaft to position it.

[0018] Step 3: Rotary welding of the workpiece. Align the laser welding head of the laser welding equipment with the connection between the connecting shaft and the anvil seat body. When the end of the second electric push rod continues to move, the rack drives the meshing gear to rotate. At the same time, the rotating shaft drives the anvil seat body on the placing seat to rotate. When the several first rotating rollers rotatably connected to the first arc-shaped clamp block and the several second rotating rollers rotatably connected to the second arc-shaped clamp block cooperate, the anvil seat body and the connecting shaft rotate synchronously, making it convenient for the weld seams to be evenly distributed on the anvil seat body and the connecting shaft while the position of the laser welding head remains unchanged.

[0019] Step 4: Cleaning of the weld seam of the workpiece. During the horizontal movement of the vertical rod, it带动 the U-shaped block, the third sliding rod, the cleaning bracket and the cleaning block to move horizontally synchronously,促使 the cleaning block to contact the surface of the weld seam. As the workpiece rotates, the cleaning block can clean the welding stains on the surface of the weld seam. At the same time, when the several abutting rods fixed on the placing seat rotate, they can intermittently abut against the second abutting wedge block,促使 the second abutting wedge block to move up and down reciprocally and abut against the cleaning bracket, and the cleaning bracket带动 the cleaning block to move reciprocally to clean the weld seam stains.

[0020] Step 5: Self-cleaning of the cleaning block. After the cleaning of the workpiece weld seam is completed, the telescopic end of the second electric push rod retracts, the second arc-shaped clamp block releases the positioning of the connecting shaft, and at the same time the electric claw带动 the first arc-shaped clamp block to move to release the clamping of the connecting shaft,使得 the first electric push rod takes the workpiece on the placing seat away from the welding seat. At the same time, the hollow rectangular rod releases the abutment against the placing seat,使得 the nozzle moves to the下方 of the cleaning block for water spraying and rinsing. After the rinsing is completed, the telescopic end of the second electric push rod continues to retract,促使 the abutting strip to release the abutment against the third abutting wedge block, and the scraper frame slides on the sliding bracket under the action of the elastic force of the eighth spring. The moving scraper frame can scrape the sewage on the cleaning block, achieving the purpose of self-cleaning of the cleaning block.

[0021] The present invention has the following beneficial effects:

[0022] 1. The welding equipment for manufacturing the anvil assembly facilitates the placement of the anvil body through the placement seat. The first electric push rod can push the placement seat into the card slot in the welding seat, achieving the purpose of positioning the welding position of the anvil body. The two first arc-shaped clamping blocks provided on the electric gripper facilitate the clamping and fixing of the connecting shaft. The second electric push rod pushes the vertical rod to move horizontally, causing the connecting shaft to coincide with the center of the anvil body. At the same time, the limiting block fixed on the vertical rod abuts against the welding seat, achieving the purpose of positioning the connecting shaft after the center coincides. The servo electric cylinder fixed on the vertical rod can drive the support plate to move downward, causing the lower end of the connecting shaft to closely adhere to the surface of the anvil body, improving the firmness of the welding end face fit. When the second electric push rod pushes the U-shaped抵触架 (it should be noted that there may be an incorrect expression here, assuming it's a specific component) to move horizontally, it causes the U-shaped抵触架 to抵触 with the first抵触楔块 fixed below the two mounting brackets, achieving the purpose of the two mounting brackets driving the second arc-shaped clamping block to move horizontally and abut against the surface of the connecting shaft for positioning, further improving the stability of the connecting shaft position during welding. Moreover, the workpiece is time-saving, labor-saving, convenient and fast during the welding positioning process. At the same time, the connecting shaft is not easily affected by external forces during welding, which can improve the welding quality and welding accuracy;

[0023] 2. In the welding equipment for manufacturing the anvil assembly, when the telescopic end of the second electric push rod continues to move, it can achieve the purpose of the U-shaped抵触架 (assuming it's a specific component) driving the rack to move horizontally, facilitating the rotation of the gear. At the same time, the rotating shaft drives the anvil body on the placement seat to rotate synchronously. Through the cooperation of several first rotating rollers rotatably connected to the first arc-shaped clamping block and several second rotating rollers rotatably connected to the second arc-shaped clamping block, it can achieve the purpose of the anvil body and the connecting shaft rotating synchronously. In the case where the position of the laser welding head remains unchanged, it is convenient for the weld seams to be evenly distributed on the anvil body and the connecting shaft, reducing the welding dead angle and improving the welding quality and welding efficiency.

[0024] It should be noted that there may be some inaccuracies in the original text such as the unclear "抵触架", and the translation is adjusted as much as possible based on the overall context.3. The welding equipment for producing the anvil seat assembly can, during horizontal movement of the vertical rod, achieve the purpose of synchronously moving the U-shaped block, the third sliding rod, the cleaning bracket, and the cleaning block, enabling the cleaning block to abut against the weld of the workpiece. As the workpiece rotates, it is convenient to clean the welding stains on the surface of the weld, improving the welding quality. At the same time, several abutting rods fixed on the placement seat can intermittently abut against the second abutting wedge during rotation, causing the second abutting wedge to move up and down reciprocally and abut against the cleaning bracket, facilitating the cleaning bracket to drive the cleaning block to reciprocate, which can further improve the cleaning effect on the welding stains. The nozzle provided on the hollow rectangular rod can flush the stains on the cleaning block after the workpiece is unloaded. The sliding bracket fixed on the cleaning bracket is convenient for sliding connection with the scraper frame. When the scraper frame can automatically move horizontally on the sliding bracket under the action of the elastic force of the eighth spring, it can automatically scrape the sewage on the cleaning block, facilitating self-cleaning of the cleaning block, reducing surface stains, and facilitating cleaning of the weld of the next workpiece.

[0043] In order to improve the welding efficiency and quality of the workpiece, refer to Figure 1-Figure 4 , when the telescopic end of the second electric push rod 7 continues to move, the purpose of driving the rack 404 to move horizontally by the U-shaped contact frame 20 can be achieved, which is convenient for driving the gear 403 in the rotating component to rotate, prompting the rotating shaft 402 to rotate on the rotating frame 401, and at the same time driving the placing seat 5 to rotate. When the cooperation of a number of first rotating rollers 24 rotatably connected to the first arc-shaped clamping block 121 and a number of second rotating rollers 25 rotatably connected to the second arc-shaped clamping block 15 is used, the purpose of enabling the nail holder body 6 and the connecting shaft 13 to rotate synchronously can be achieved, so that the position of the welding head of the laser welding equipment remains unchanged, which is convenient for the weld seams to be evenly distributed on the nail holder body 6 and the connecting shaft 13, reducing the welding dead angle, and improving the welding quality and welding efficiency.

[0044] Embodiment Three, this embodiment is an improvement made on the basis of Embodiment Two. Specifically, please refer to Figures 1-8 , a U-shaped block 26 is arranged above the welding seat 2. A third sliding rod 27 is fixed on the U-shaped block 26. The third sliding rod 27 is elastically connected to the vertical rod 8 through a fourth spring 28. Two fourth sliding rods 29 are fixed inside the U-shaped block 26. A cleaning bracket 30 is slidably connected to the fourth sliding rods 29. The cleaning bracket 30 is elastically connected to the U-shaped block 26 through a fifth spring 31. One end of the cleaning bracket 30 is fixed with a cleaning block 32.

[0045] A second contact wedge 33 is arranged below the cleaning bracket 30. The second contact wedge 33 is elastically connected to the second contact wedge 33 through a sixth spring 34. A number of equally spaced contact rods 35 are fixed on the circumferential surface of the placing seat 5.

[0046] A fifth sliding rod 36 is fixed on the welding seat 2. A hollow rectangular rod 37 is slidably connected to the fifth sliding rod 36. The hollow rectangular rod 37 is elastically connected to the welding seat 2 through a seventh spring 38. One end of the hollow rectangular rod 37 abuts against the placing seat 5. A nozzle 39 is fixed on the hollow rectangular rod 37.

[0047] A sliding bracket 40 is fixed on the cleaning bracket 30. One end of the cleaning block 32 is provided with a scraping bracket 41. The upper end of the scraping bracket 41 is elastically connected to the sliding bracket 40 through an eighth spring 42. A third contact wedge 43 is fixed on the scraping bracket 41. A contact strip 44 is fixed on the mounting bracket 16.

[0048] On the surface of the workpiece weld, stains are likely to appear due to the influence of welding parameters, welding processes, and welding materials. It is necessary to clean it to improve the welding quality of the workpiece. The vertical rod 8 can achieve the purpose of synchronously moving the C-shaped block 26, the third sliding rod 27, the cleaning bracket 30, and the cleaning block 32 during horizontal movement. With the cooperation of the fourth spring 28 on the third sliding rod 27, the cleaning block 32 can always be pressed against the weld of the workpiece. As the workpiece rotates, it is convenient to clean the welding stains on the weld surface, which can improve the welding quality. To improve the cleaning effect, refer to Figure 4-Figure 5 , when the plurality of abutting rods 35 fixed on the placing seat 5 rotate, they can intermittently abut against the second abutting wedge 33. The sixth spring 34 continuously stores and releases elastic force, prompting the second abutting wedge 33 to move up and down reciprocally and abut against the cleaning bracket 30, causing one end of the cleaning bracket 30 to reciprocally slide on the two fourth sliding rods 29 within the C-shaped block 26. At the same time, the fifth spring 31 continuously stores and releases elastic force, facilitating the cleaning block 32 to reciprocally move on the weld surface for cleaning, which can further improve the cleaning effect of the welding stains.

[0049] After cleaning, the surface of the cleaning block 32 needs to be self-cleaned to facilitate the cleaning of the weld of the next workpiece. Refer to Figure 2-Figure 7 , when the workpiece is loaded, the placing seat 5 moves horizontally and abuts against the hollow rectangular rod 37, prompting the hollow rectangular rod 37 to slide on the fifth sliding rod 36, which can hide the spray head 39. At the same time, during the horizontal movement of the vertical rod 8, the mounting bracket 16 can be realized to drive the abutting strip 44 to move and abut against the third abutting wedge 43 fixed on the scraping plate bracket 41, prompting the scraping plate bracket 41 to move horizontally on the sliding bracket 40. At the same time, the eighth spring 42 stores elastic force. When the stains on the surface of the workpiece weld are cleaned, the telescopic end of the second electric push rod 7 retracts a certain distance, the rack 404 and the gear 403 are disengaged, and when the telescopic end of the second electric push rod 7 disengages from the welding seat 2, at this time, the second arc-shaped clamp 15 is separated from the connecting shaft 13, and at the same time, the electric claw 12 drives the first arc-shaped clamp 121 to move to release the clamping of the connecting shaft 13, enabling the first electric push rod 4 to take the workpiece on the placing seat 5 away from the welding seat 2. When the hollow rectangular rod 37 is disengaged from the abutment with the placing seat 5, the spray head 39 automatically moves to the lower side of the cleaning block 32. By controlling the external equipment of the spray head through the controller, water is conveyed into the spray head 39 for spraying and rinsing. After the rinsing is completed, the telescopic end of the second electric push rod 7 continues to retract, prompting the abutting strip 44 to disengage from the third abutting wedge 43, facilitating the scraping plate bracket 41 to slide on the sliding bracket 40 under the action of the elastic force of the eighth spring 42. At the same time, the scraping plate bracket 41 scrapes the sewage on the cleaning block 32 for self-cleaning. Finally, the second electric push rod 7 drives the vertical rod 8 to reset.

[0050] Embodiment 4

[0051] Please refer to Figures 1-8 , a welding method for a welding device used in the production of a staple cartridge assembly, comprising the following specific steps:

[0052] Step 1, workpiece feeding. Place the staple cartridge body 6 into the placement seat 5. Push the rotating assembly horizontally through the first electric push rod 4, and push the placement seat 5 into the slot 3 in the welding seat 2 to position the staple cartridge body 6. Clamp the connecting shaft 13 with two first arc-shaped clamping blocks 121 provided on the electric claw 12. Push the vertical rod 8 horizontally through the second electric push rod 7. When the connecting shaft 13 coincides with the center of the staple cartridge body 6, the limiting block 14 fixed on the vertical rod 8 abuts against the welding seat 2, then the vertical rod 8 stops moving. The servo electric cylinder 10 fixed on the vertical rod 8 drives the support plate 11 to move downward, so that the lower end of the connecting shaft 13 abuts tightly against the surface of the staple cartridge body 6;

[0053] Step 2, workpiece positioning. The end of the second electric push rod 7 continues to move to push the U-shaped abutting frame 20 horizontally, causing the U-shaped abutting frame 20 to abut against the first abutting wedge blocks 21 fixed below the two mounting frames 16. The two mounting frames 16 drive the second arc-shaped clamping blocks 15 to move horizontally and abut against the surface of the connecting shaft 13 to position it;

[0054] Step 3, rotary welding of the workpiece. Align the laser welding head of the laser welding device with the connection between the connecting shaft 13 and the staple cartridge body 6. When the end of the second electric push rod 7 continues to move, the rack 404 drives the meshing gear 403 to rotate. At the same time, the rotating shaft 402 drives the staple cartridge body 6 on the placement seat 5 to rotate. When cooperating with a number of first rotating rollers 24 rotatably connected on the first arc-shaped clamping block 121 and a number of second rotating rollers 25 rotatably connected on the second arc-shaped clamping block 15, the staple cartridge body 6 and the connecting shaft 13 rotate synchronously, so that it is convenient for the weld seams to be evenly distributed on the staple cartridge body 6 and the connecting shaft 13 under the condition that the position of the laser welding head remains unchanged;

[0055] Step 4, cleaning of the weld seam of the workpiece. During the horizontal movement of the vertical rod 8, it drives the U-shaped block 26, the third sliding rod 27, the cleaning bracket 30 and the cleaning block 32 to move horizontally synchronously, so that the cleaning block 32 can contact the surface of the weld seam. As the workpiece rotates, the cleaning block 32 can clean the welding stains on the surface of the weld seam. At the same time, when a number of abutting rods 35 fixed on the placement seat 5 rotate, they can intermittently abut against the second abutting wedge block 33, causing the second abutting wedge block 33 to move up and down reciprocally and abut against the cleaning bracket 30. The cleaning bracket 30 drives the cleaning block 32 to move reciprocally to clean the weld seam stains;

[0056] Step 5, self-cleaning of the cleaning block. After the workpiece weld is cleaned, the telescopic end of the second electric push rod 7 is retracted, and the second arc-shaped clamping block 15 releases the positioning of the connecting shaft 13. At the same time, the electric clamping jaw 12 drives the first arc-shaped clamping block 121 to move and release the clamping of the connecting shaft 13, so that the first electric push rod 4 takes the workpiece on the placement seat 5 away from the welding seat 2. At the same time, the hollow rectangular rod 37 releases the interference with the placement seat 5, so that the nozzle 39 moves to the bottom of the cleaning block 32 for water spraying and flushing. After the flushing is completed, the telescopic end of the second electric push rod 7 continues to retract, prompting the interference bar 44 to release the interference with the third interference wedge 43, and the scraper frame 41 slides on the sliding bracket 40 under the action of the elastic force of the eighth spring 42. The moving scraper frame 41 can scrape off the sewage on the cleaning block 32, thereby achieving the purpose of self-cleaning of the cleaning block 32.
