Description

Technical Field

[0001] This invention belongs to the technical field of medical device processing equipment, and particularly relates to a welding device for a continuous-fire ligature magazine. Background Technology

[0002] A clip applicator is a surgical instrument used to clamp tissue clips during surgical procedures. A multi-shot clip applicator is a further improvement on the single-shot applicator, achieving continuous clipping by placing multiple ligation clips within a magazine, thus improving surgical efficiency. See the invention patent application number "202111376487.X". Multi-shot clip applicators typically have a guide wire within the magazine to ensure the stability and consistency of the ligation clips' position within the magazine. Currently, most technologies involve manual hand-held welding using laser welding equipment, which results in low welding efficiency and high labor intensity.

[0003] To address this issue, people have conducted exploratory research in long-term production and daily life practices. For example, Chinese invention patent application discloses a welding device [Application No.: CN 202311098378.5]. This invention application includes: a workbench with a processing position; a clamp detachably mounted on the workbench for supporting and limiting the contact and the bracket in a first direction; a driving mechanism mounted on the workbench for driving the clamp to move along a second direction, causing the overlapping portion of the contact and the bracket to move to or away from the processing position; a first positioning mechanism mounted on the workbench, which, when the overlapping portion is located at the processing position, limits the contact and the bracket in a third direction and cooperates with the clamp to limit the contact and the bracket in the second direction; a first electrode and a second electrode, mounted on opposite sides of the processing position along the third direction, and the first electrode and the second electrode can be relatively close to each other to press the overlapping portion at the processing position and weld the contact to the bracket; wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0004] While this invention has the advantage of enabling automatic welding of the bracket and the contact, thus improving processing efficiency, it cannot be applied to welding between magazine compartment components. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a welding device for a repeating magazine clip that can be used for welding magazine components.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] A welding device for a magazine with a lash clip includes an installation platform. The installation platform is provided with a drive mechanism for moving a laser welding head. The laser welding head is connected to the drive mechanism. A clamping assembly for fixing the magazine is located on one side of the drive mechanism and is fixedly connected to the installation platform. Moving the laser welding head can position the laser welding head directly above the clamping assembly.

[0008] In the aforementioned welding equipment for a magazine with a tethered clip, the clamping assembly includes a clamping base fixedly connected to the mounting platform and a clamping platform fixedly connected to the clamping base. The clamping platform is provided with at least one set of processing bases for placing the magazine. The clamping base or the clamping platform is also provided with at least one clamping component. One end of the clamping component can be pressed against or away from the surface of the processing base. The equipment also includes a positioning component provided on the clamping base or the clamping platform. The positioning component is located on the outer side of both ends of the processing base.

[0009] In the aforementioned welding equipment for a magazine with a breech-loading clamp, the processing base includes a first base and a second base, with a gap between the first base and the second base; the magazine includes a magazine housing and a positioning wire located inside the magazine housing, the positioning wire being located inside the first base, one end of the magazine housing being located inside the first base, and the other end passing through the gap and extending into the second base.

[0010] In the aforementioned welding equipment for a magazine with a grappling hook, one end of the positioning wire is pressed onto the side of the positioning component, and the other end extends towards the gap and is flush with the end of the first base. Both ends of the magazine shell are pressed onto the positioning component. The first base has a first processing table protruding from the surface of the first base. The surface of the first processing table has a magazine shell processing groove that is recessed inward to accommodate the magazine shell. The center of the magazine shell processing groove has a strip-shaped protrusion. The surface of the magazine shell has a wire processing groove that is recessed inward to accommodate the positioning wire. The depth of the wire processing groove is less than the depth of the magazine shell processing groove.

[0011] In the aforementioned welding equipment for the magazine of continuously firing clips, the positioning component includes a limiting plate fixedly connected to one end of the processing base and a linear drive structure disposed on the clamping platform and located at the other end of the processing base. The linear drive structure can be pressed onto the end of the processing base. The linear drive structure includes a drive cylinder fixedly connected to the clamping platform and a push rod connected to the drive cylinder. Moving the push rod can press the push rod onto the end of the processing base.

[0012] In the aforementioned welding equipment for a magazine with a grappling hook, the clamping assembly includes a clamping cylinder fixedly connected to a clamping base and a lifting arm drivenly connected to the clamping cylinder, with one end of the lifting arm extending directly above the processing base.

[0013] In the aforementioned welding equipment for the magazine with grappling clip, the processing base is provided in two sets and is located on both sides of the clamping platform. The clamping components are provided in several sets and are fixedly connected to the clamping base. The clamping components are located on both sides of the clamping platform and one end extends above the processing base.

[0014] In the aforementioned welding equipment for a magazine with a tethered clip, the drive mechanism includes a horizontal drive assembly, a vertical drive assembly, and a vertical drive assembly that are connected to each other. The horizontal drive assembly or the vertical drive assembly is connected to the mounting platform, and the laser welding head is connected to the vertical drive assembly. The horizontal drive assembly, the vertical drive assembly, and the vertical drive assembly are perpendicular to each other.

[0015] In the aforementioned welding equipment for a magazine with a tethered clip, the vertical drive assembly includes a connecting plate connected to the horizontal drive assembly or the longitudinal drive assembly. One side of the connecting plate is provided with a long strip-shaped drive guide seat, and a slider is slidably connected to the drive guide seat. The laser welding head is fixedly connected to the slider.

[0016] In the aforementioned welding equipment for the magazine with ligature clips for rapid-fire, an optical fiber support is also fixedly installed on the drive mechanism. The base plate of the optical fiber support is arc-shaped, and limit plates are symmetrically arranged on both sides of the base plate.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. This invention provides a welding device specifically for welding the magazine shell and positioning wire between the magazine and the magazine. Compared with the manual welding method used in the prior art, it improves work efficiency and reduces work intensity.

[0019] 2. The present invention provides a processing base for placing and clamping the magazine. After the positioning component positions the magazine on the processing base to a suitable position, the clamping component is used to clamp it, thereby realizing the clamping processing of the magazine.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 As shown, a welding device for a magazine with a lash clip includes a mounting platform 6. The mounting platform 6 is provided with a drive mechanism 7 for moving a laser welding head 8. The laser welding head 8 is connected to the drive mechanism 7. A clamp assembly 9 for fixing the magazine 100 is located on one side of the drive mechanism 7 and is fixedly connected to the mounting platform 6. Moving the laser welding head 8 can position the laser welding head 8 directly above the clamp assembly 9.

[0029] In this invention, during use, the magazine compartment 100 is fixed by the clamping assembly 9, and the driving mechanism 7 drives the laser welding head 8 to move above the clamping assembly 9, that is, above the magazine compartment 100, thereby realizing the welding operation between the components of the magazine compartment 100. Therefore, this invention provides a welding device specifically for welding between the magazine housing 101 and the positioning wire 102 of the magazine compartment 100, which improves work efficiency and reduces labor intensity compared with the manual welding method used in the prior art.

[0030] Combination Figure 1 and Figure 3As shown, the clamping assembly 9 includes a clamping base 1 fixedly connected to the mounting platform 6 and a clamping platform 2 fixedly connected to the clamping base 1. The clamping platform 2 is provided with at least one set of processing bases 3 for placing the magazine 100. The clamping base 1 or the clamping platform 2 is also provided with at least one clamping component 4. One end of the clamping component 4 can be pressed onto or away from the surface of the processing base 3. It also includes a positioning component 5 provided on the clamping base 1 or the clamping platform 2. The positioning component 5 is located on the outer side of both ends of the processing base 3.

[0031] In use, the magazine 100 is placed on the processing base 3, and the positioning component 5 is used to position the magazine 100 to a predetermined position. At this time, the clamping component 4 clamps the magazine 100 onto the processing base 3 to prevent the magazine 100 from shifting position during processing. Therefore, this invention provides a processing base 3 for placing and clamping the magazine 100. After the positioning component 5 positions the magazine 100 on the processing base 3 to a suitable position, the clamping component 4 is used to clamp it, thereby realizing the clamping processing of the magazine 100.

[0032] Combination Figure 4 and Figure 5 As shown, the processing base 3 includes a first base 31 and a second base 32, with a gap 33 between the first base 31 and the second base 32; the magazine 100 includes a magazine housing 101 and a positioning wire 102 located inside the magazine housing 101. The positioning wire 102 is located inside the first base 31. One end of the magazine housing 101 is located inside the first base 31, and the other end passes through the gap 33 and extends into the second base 32.

[0033] Because the housing 101 needs to accommodate not only the ligation clip but also a structure for moving the ligation clip, the positioning wire 102 used to ensure the position of the ligation clip within the housing 101 is generally much shorter than the housing 101 itself. Therefore, the processing base 3 adopts a two-section structure: a first base 31 and a second base 32. The first base 31 accommodates the positioning wire 102 and part of the housing 101 during processing, while the second base 32 only needs to accommodate part of the housing 101. The two differ slightly in structure. Figure 1 and Figure 2 As shown, one end of the positioning wire 102 is pressed against the side of the positioning component 5, and the other end extends towards the gap 33 and is flush with the end of the first base 31. Both ends of the housing 101 are pressed against the positioning component 5. The housing 101 is positioned by the limiting plates 51 on both sides and the linear drive structure 52. The positioning wire 102 is positioned by the length of the limiting plates 51 and the first base 31. Therefore, the first base 31 and the second base 32 are separated by the gap 33 to facilitate the positioning of the positioning wire 102 during processing.

[0034] Specifically, the first base 31 is provided with a first processing table 34 protruding from the surface of the first base 31. The surface of the first processing table 34 is provided with a recessed groove 35 for accommodating the housing shell 101. The center of the groove 35 is provided with a strip-shaped protrusion 36. The surface of the housing shell is provided with a recessed groove 37 for accommodating the positioning wire 102. The depth of the groove 37 is less than the depth of the groove 35.

[0035] In use, the positioning wire 102 is placed in the wire processing groove 37, with one end of the positioning wire 102 pressed against the limiting plate 51 and the other end flush with the end of the first base 31, thus achieving positioning. The silo housing 101 is then placed in the silo housing processing groove 35, and the linear drive structure 52 drives the silo housing 101 to move back and forth along the silo housing processing groove 35 until one end of the silo housing 101 presses against the limiting plate 51 to complete positioning. Since the strip-shaped protrusion 36 is located at the center of the silo housing processing groove 35, the positioning wire 102 is also aligned with the center of the inner surface of the silo housing 101 at this time.

[0036] Preferably, the wire processing groove 37 and the housing shell processing groove 35 are arranged parallel to each other. This ensures that after processing, the housing shell 101 and the positioning wire 102 are parallel to each other.

[0037] like Figure 3 As shown, the processing base 3 has two sets, located on both sides of the clamping platform 2. Several clamping components 4 are fixedly connected to the clamping base 1, with one end extending above the processing base 3 on both sides of the clamping platform 2. This facilitates the positioning of the clamping components 4 and avoids interference during processing.

[0038] like Figure 3 As shown, the positioning component 5 includes a limiting plate 51 fixedly connected to one end of the processing base 3 and a linear drive structure 52 disposed on the clamping platform 2 and located at the other end of the processing base 3. The linear drive structure 52 can be pressed onto the end of the processing base 3.

[0039] Specifically, the linear drive structure 52 includes a drive cylinder 53 fixedly connected to the clamping platform 2 and a push rod 54 connected to the drive cylinder 53. Moving the push rod 54 allows it to press against the end of the processing base 3. In this invention, the linear drive structure 52 can adopt other specific structures in the prior art besides the specific structure described above, as long as it can achieve linear drive.

[0040] like Figure 3As shown, the clamping assembly 4 includes a clamping cylinder 41 fixedly connected to the clamping base 1 and a lifting arm 42 drivenly connected to the clamping cylinder 41. One end of the lifting arm 42 extends directly above the processing base 3. The clamping cylinder 41 drives the lifting arm 42 to move up and down to clamp or release the magazine 100.

[0041] Combination Figure 1 and Figure 2 As shown, the drive mechanism 7 includes a horizontal drive assembly 71, a vertical drive assembly 72, and a vertical drive assembly 73 connected to each other. The horizontal drive assembly 71 or the vertical drive assembly 72 is connected to the mounting platform 6, and the laser welding head 8 is connected to the vertical drive assembly 73. The horizontal drive assembly 71, the vertical drive assembly 72, and the vertical drive assembly 73 are perpendicular to each other.

[0042] Specifically, the vertical drive assembly 73 includes a connecting plate 74 connected to the horizontal drive assembly 71 or the longitudinal drive assembly 72. One side of the connecting plate 74 is provided with a long, narrow drive guide seat 75. A slider 76 is slidably connected to the drive guide seat 75, and the laser welding head 8 is fixedly connected to the slider 76. The sliding of the slider 76 can be achieved using existing devices for linear drive, such as a lead screw and sleeve mechanism or a cylinder device. The specific structures of the horizontal drive assembly 71 and the longitudinal drive assembly 72 can be similar to those of the vertical drive assembly 73, differing only in the orientation, which leads to a difference in the drive direction.

[0043] In use, the position of the laser welding head 8 is adjusted in the three dimensions of horizontal, vertical and vertical by using the horizontal drive component 71, the longitudinal drive component 72 and the vertical drive component 73 respectively, so that it can complete the welding operation between the housing shell 101 and the positioning wire 102.

[0044] like Figure 1 As shown, a fiber optic bracket 10 is also fixedly mounted on the drive mechanism 7. The base plate 11 of the fiber optic bracket 10 is arc-shaped, and limiting plates 12 are symmetrically arranged on both sides of the base plate 11. The optical fiber (not shown in the figure) connected to the end of the laser welding head 8 can be placed on the base plate 11 of the fiber optic bracket 10, and the limiting plates 12 are used to limit and store the optical fiber. Therefore, the present invention also provides a fiber optic bracket 10 on the top of the drive mechanism 7. The optical fiber connected to the laser welding head 8 can be supported and regulated by the fiber optic bracket to prevent interference between the optical fiber and other components during use.

[0045] The working principle of this invention is as follows: In use, the positioning wire 102 is placed in the wire processing groove 37, with one end of the positioning wire 102 pressed against the limiting plate 51 and the other end flush with the end of the first base 31, thereby achieving positioning. Then, the bin housing 101 is placed in the bin housing processing groove 35, and the drive cylinder 53 is activated. The drive cylinder 53 drives the push rod 54, causing the push rod 54 to push the bin housing 101 back and forth along the bin housing processing groove 35 until one end of the bin housing 101 is pressed against the limiting plate 51 to complete the positioning. Since the strip-shaped protrusion 36 is located at the center of the bin housing processing groove 35, the positioning wire 102 is also in contact with the center position of the inner surface of the bin housing 101 at this time. The clamping cylinder 41 is then activated, driving the lifting arm 42 to descend and press against the surface of the magazine housing 101. This clamps the magazine housing 101 and the positioning wire 102 simultaneously onto the processing base 3, preventing positional shifts between them during processing. The horizontal drive assembly 71, vertical drive assembly 72, and vertical drive assembly 73 are then used to adjust the position of the laser welding head 8 in the horizontal, vertical, and vertical dimensions, respectively, to complete the welding operation between the magazine housing 101 and the positioning wire 102. Therefore, this invention provides a welding device specifically for welding the magazine housing 101 and the positioning wire 102 of a magazine 100, which improves work efficiency and reduces labor intensity compared to the manual welding methods used in the prior art.
