Referring to fig. 1-3, an embodiment of the present invention provides a guidewire welding system 100 for welding a guidewire. It should be noted that, the guide wire welding system 100 of the present invention is particularly suitable for a guide wire with a three-layer structure, that is, the guide wire includes a core wire, an inner spring and an outer spring, the distal end of the core wire is ground to form a grinding section with a smaller diameter, the inner spring is sleeved on the distal end of the core wire grinding section, the outer spring is sleeved on the inner spring and the whole grinding section, and finally, the distal end of the core wire and the outer spring are welded by welding the proximal end of the outer spring and the core wire, so as to obtain the guide wire of the finished product. The present invention will be described in detail by taking the above three-layer structure of the guide wire as an example.

The wire welding system 100 includes a laser welding device (not shown) for emitting laser light to weld a target location, an outer layer welding device 10, an end welding device 20, and a base 30. The outer layer welding device 10 is used for fixing the guide wire, so that the laser welding device welds the proximal end of the outer layer spring, and the proximal end of the outer layer spring is welded on the core wire. The end welding device 20 is used for fixing the guide wire and clamping the distal end of the guide wire, so that the laser welding device welds the distal end of the core wire, and the distal end of the guide wire is welded into a ball shape. The outer layer welding device 10 and the end part welding device 20 are arranged on the base 30 at intervals, the outer layer welding device 10 comprises a first welding component 11 and a first fixing component 12, the proximal end of the outer layer spring is fixed on the first welding component 11, and the guide wire is used for welding the outer layer spring on the first welding component 11. The first fixing component 12 is used for fixing the distal end of the guide wire, and the first fixing component 12 is arranged between the first welding component 11 and the end welding device 20. The end welding device 20 includes a second welding assembly 21 and a second fixing assembly 22, the second welding assembly 21 being adapted to clamp the distal end of the guide wire so that the guide wire is perpendicular to the base 30. The second fixing component 22 may fix the proximal end of the guide wire, the second fixing component 22 and the second welding component 21 are disposed on the same side of the base 30, and the second fixing component 22 and the second welding component 21 are disposed on opposite sides of the first welding component 11.

Because the length of the guide wire is long, when the proximal end of the outer layer spring is welded, the distal end portion of the guide wire needs to be fixed, so that the influence of shaking of the distal end of the guide wire on the welding effect of the outer layer spring is avoided. The distal end of the guidewire may be passed through the first fixation assembly 12 and ultimately received within the first fixation assembly 12 to limit wobble of the distal end of the guidewire. The laser welding device is always kept perpendicular to the welding part of the guide wire, and is kept motionless in the welding process.

Referring to fig. 4 to 6, the first welding assembly 11 includes a rotation mechanism 111 and a driving mechanism 112, and the driving mechanism 112 can drive the rotation mechanism 111 to rotate. The driving mechanism 112 is connected to a side of the rotating mechanism 111 away from the first fixing assembly 12. The rotating mechanism 111 includes a rotating module 1111 and a first working module 1112, the rotating module 1111 is disposed near the driving mechanism 112, and the first working module 1112 is disposed on a surface of the rotating module 1111 near the first fixing assembly 12. Specifically, the driving mechanism 112 may be a motor, etc., and the rotating module 1111 is in a cylindrical structure, and when the driving mechanism 112 drives the rotating module 1111 to rotate, the rotating module 1111 rotates around its central axis. The rotation module 1111 is provided with a fixing position 1113 at a center position of a surface of the rotation module 1111 near the driving mechanism 112, and the fixing position 1113 penetrates from the surface of the rotation module 1111 near the driving mechanism 112 to a surface far from the driving mechanism 112. In an embodiment of the invention, the fixation site 1113 is a cylindrical structure, the proximal end of the guidewire is received over the fixation site 1113, and the distal end of the guidewire passes through the fixation site 1113 and into the first working module 1112. The first working module 1112 includes a first platform 1114, where the first platform 1114 has a semi-cylindrical structure, and a first accommodating groove 1115 is provided on the first platform 1114, and the first accommodating groove 1115 is used for accommodating a guide wire. The central axis of the first accommodating groove 1115 in the length direction is coaxial with the central axis of the fixing position 1113 in the length direction, that is, the guide wire is ensured to pass through the fixing position 1113 and be placed in the first accommodating groove 1115, and the whole guide wire is in a linear state.

Further, with continued reference to fig. 4-6, the first working module 1112 also includes a first clamp 1116, the first clamp 1116 being disposed on a side of the first platform 1114 remote from the rotating module 1111. The first clamping member 1116 includes a first baffle 1117 and a first clamping portion 1118, which are perpendicular to the first platform 1114, the first clamping portion 1118 is disposed on a surface of the first baffle 1117, which is close to the first platform 1114, and the first clamping portion 1118 can press the guide wire located on the first accommodating groove 1115. By the arrangement of the first baffle 1117, the first clamping portion 1118 is fixed to the first baffle 1117, so that a height difference exists between the first clamping portion 1118 and the first platform 1114. The first clamping part 1118 can move towards the first platform 1114, so as to compress the guide wire positioned on the first accommodating groove 1115, and further ensure that the guide wire is fixed on the first platform, and then the welding work of the outer layer spring can be performed. After the guide wire is secured to the first platform 1114, the proximal end of the outer spring is then between the first platform 1114 and the first securing member 12, and the laser welding device will also correspond between the first platform 1114 and the first securing member 12 directly above the proximal end of the outer spring. The proximal end part of the outer spring to be welded is arranged between the first platform 1114 and the first fixing component 12, so that the interference or influence of other parts during welding can be avoided, and the damage of the parts caused by the fact that laser emitted by the laser welding device irradiates the other parts can be avoided. Because the outer layer spring is in a spiral structure, and the outer layer spring is welded on the core wire, at least one circle of welding is needed along the circumferential direction of the proximal end of the outer layer spring, so that the proximal end of the outer layer spring can be firmly welded on the core wire. Therefore, when the outer spring is welded, the driving mechanism 112 can be started, the driving mechanism 112 drives the rotating mechanism 111 to rotate integrally, and then drives the guide wire fixed on the rotating mechanism 111 to rotate, so that laser irradiates on the circumferential direction of the guide wire, and the proximal end of the outer spring is welded at least one circle circumferentially.

It should be noted that the first platform 1114 has a semi-cylindrical structure, so as to facilitate the user to take down, fix, etc. the guide wire and observe the guide wire. The guide wire welding system 100 of the present invention is applicable to a bent guide wire including a distal bent portion and a straight portion connected to the bent portion, the bent portion being a guide wire subjected to a pre-bending treatment, and an outer spring being only sleeved on the bent portion, as shown in fig. 7. The guidewire welding system 100 of the present invention is particularly useful for welding outer springs of bent guidewires, for example, when welding outer springs of bent guidewires is desired, since the proximal end of the outer spring of the bent guidewire is at the junction of the bend and the straight line, laser light may impinge on the bend and not on the proximal end of the outer spring when welding the outer spring. The guidewire welding system 100 of the present invention is provided with the first baffle 1117, and when welding a curved guidewire, the curved portion of the curved guidewire can be shifted to a side of the first baffle 1117 away from the first platform 1114. The bending part of the bending guide wire is clamped on the first baffle 1117, and at the moment, when the proximal end of the outer layer spring is welded, the bending part can not be blocked or interfered, so that the outer layer spring of the bending guide wire can be accurately welded.

Referring to fig. 6 and 8, when the guide wire is a straight guide wire, the first fixing component 12 is required to receive the distal end of the guide wire, so as to ensure that the distal end of the guide wire does not swing or shake at will during the rotation welding process. The first fixing component 12 includes a first passing portion 121 and a first stabilizing portion 122, wherein the first passing portion 121 is disposed near the first welding component 11, and the first stabilizing portion 122 is disposed on a side of the first passing portion 121 away from the first welding component 11. The first through portion 121 includes a first through hole 1211 penetrating the first through portion 121, and the first through hole 1211 is coaxially disposed with the central axis of the first accommodating groove 1115 in the length direction. The first stabilizing section 122 includes a placement groove 1221, and a central axis of the placement groove 1221 in a length direction is disposed coaxially with the first through hole 1211. It should be noted that, the distal end of the guide wire passes through the first through hole 1211, and is finally received in the placement groove 1221. The placement groove 1221 is a through hole structure that is sealed in the circumferential direction, the first through hole 1211 and the central axis of the first accommodating groove 1115 in the length direction are coaxially arranged, and the central axis of the placement groove 1221 in the length direction and the first through hole 1211 are coaxially arranged, so that after the distal end of the guide wire is accommodated in the placement groove 1221 and the first through hole 1211, the whole guide wire can be ensured to be in a straight line, and further, when the outer spring is welded, the whole guide wire is ensured to coaxially rotate, and further, the condition that the guide wire shakes during welding and cannot accurately weld the proximal end of the outer spring is avoided.

Referring to fig. 9 to 11, the end welding device 20 is suitable for distal welding of bent guide wires and linear guide wires, and in particular, the second fixing assembly 22 includes a second passing portion 221 spaced from the base 30 in a direction perpendicular to the base 30, that is, a height difference exists between the second passing portion 221 and the base 30. The second through portion 221 is provided with a plurality of second through holes 2211 penetrating through the second through portion 221, a central axis of the second through holes 2211 is parallel to a direction perpendicular to the base 30, and the base 30 is provided with through grooves 31 at positions corresponding to the plurality of second through holes 2211. The second welding assembly 21 includes a second working module 211, the second working module 211 being disposed on a side of the second pass-through portion 221 remote from the base 30. The second working module 211 includes a clamping mechanism 212, where the clamping mechanism 212 includes a clamping fixing portion 2121, a clamping moving portion 2122, a connecting rod 2120, and an elastic member (not shown), one end of the elastic member abuts against the clamping fixing portion 2121, the other end of the elastic member is connected to one end of the connecting rod 2120, and the other end of the connecting rod 2120 is connected to the clamping moving portion 2122. Specifically, the clamping fixing portion 2121 is fixedly disposed on the second welding assembly 21, the clamping moving portion 2122 is movable relative to the clamping fixing portion 2121, one end of the connecting rod 2120 is disposed in the clamping fixing portion 2121, and the other end of the connecting rod 2120 is disposed in the clamping moving portion 2122, so as to define a moving direction of the clamping moving portion 2122, so that the clamping moving portion 2122 can only move along a length direction of the connecting rod 2120. In an embodiment of the present invention, the elastic member is a spring, and the elastic member maintains a space between the clamping and fixing portion 2121 and the clamping and moving portion 2122, and when the clamping and moving portion 2122 needs to move toward the clamping and fixing portion 2121, a force in a direction toward the clamping and fixing portion 2121 needs to be applied to the clamping and moving portion 2122, so as to compress the elastic member and move the clamping and moving portion 2122 toward the clamping and fixing portion 2121. When the force applied to the clamping moving portion 2122 is removed, the elastic member is restored, and the clamping moving portion 2122 is moved in a direction away from the clamping fixing portion 2121 until an initial state.

Further, referring to fig. 9 to 11, the clamping fixing portion 2121 extends to the outside of the second working module 211 to form a first clamping portion 2123, and the clamping moving portion 2122 extends to the outside of the second working module 211 to form a second clamping portion 2124. The clamping fixture 2121 and the first clamping portion 2123 are integrally formed in a zigzag structure, and the clamping movable portion 2122 and the second clamping portion 2124 are integrally formed in a zigzag structure. In the initial state, the first clamping portion 2123 and the second clamping portion 2124 abut against each other. When the clamping moving part 2122 moves toward the clamping fixing part 2121, the first clamping part 2123 and the second clamping part 2124 are away from each other, as shown in fig. 11. The first clamping portion 2123 is provided with a first groove 2125 penetrating the first clamping portion 2123. The second clamping portion 2124 is provided with a second groove 2126 penetrating through the second clamping portion 2124, the first groove 2125 and the second groove 2126 are disposed parallel to the second through hole 2211, and the first groove 2125 and the second groove 2126 are disposed correspondingly, that is, the first groove 2125 and the second groove 2126 together form a through hole structure 2127. Specifically, when the distal end of the linear guide wire needs to be welded, the clamping moving portion 2122 is moved toward the clamping fixing portion 2121, so that the first clamping portion 2123 and the second clamping portion 2124 are separated from each other, and the first groove 2125 and the second groove 2126 are separated from each other. At this time, the distal end of the guide wire may be passed through the through groove 31 and then passed through one of the second through holes 2211, and the distal end of the guide wire may be aligned with the first groove 2125 or the second groove 2126. The clamping movement 2122 is then moved away from the clamping fixture 2121, bringing the first clamping portion 2123 and the second clamping portion 2124 closer together, the first groove 2125 and the second groove 2126 closer together, and thereby clamping the distal end of the guide wire, which is finally clamped within the through-hole structure 2127 formed by the first groove 2125 and the second groove 2126 together. At this time, the distal end of the guide wire may be welded, and when the welding is completed, the clamping moving portion 2122 is moved toward the clamping fixing portion 2121, the first clamping portion 2123 and the second clamping portion 2124 are away from each other, and the first groove 2125 and the second groove 2126 are away from each other, so that the guide wire is not clamped any more, and the guide wire may be moved out of the second working module 211.

With continued reference to fig. 9 to 11, the second fixing assembly 22 further includes a second platform 222, a second baffle 223, and a second clamping member 224, wherein the second platform 222 and the second clamping member 224 are fixed on the second baffle 223, and the second clamping member 224 is close to a side of the second platform 222 away from the base 30. The second platform 222 is disposed parallel to the second through portion 221, and the second platform 222 is disposed on a side of the second through portion 221 away from the base 30 and spaced apart from the second through portion 221.
