Description

Technical Field

[0001] The present invention relates to the technical field of wire stripping for wire pretreatment, and specifically to a wire stripping device for wire pretreatment. Background Art

[0002] In the manufacturing of medical devices, the wire stripping process is one of the key steps. Medical wires are usually used to manufacture catheters, sensor connecting wires, pacing leads, etc. These wires often have extremely fine diameters, complex structures, and strict insulation requirements. For example, the diameters of the wires used in cardiac rhythm management, neuromodulation, and radiofrequency ablation treatments are continuously decreasing, posing extremely high requirements for wire stripping accuracy and quality. The processing and treatment of wires are indispensable links in the production process. Wires usually consist of a conductive core and an insulating outer skin. Before subsequent processes (such as welding, connection, plug installation, etc.), the insulating outer skin of the wire needs to be stripped to expose the conductive core. Traditional wire stripping methods mainly rely on manual operation. Workers use wire stripping pliers or other manual tools for wire stripping. However, this method has many drawbacks: First, manual wire stripping is inefficient and difficult to meet the needs of large-scale production; second, the stability of manual operation is poor, and the wire stripping quality varies, and it is easy to have situations where the insulating skin is not completely stripped or the wire core is damaged; in addition, manual wire stripping requires high operation skills from workers and has a large labor intensity, which is prone to fatigue and operation errors. Therefore, the wire stripping device plays a crucial role in wire pretreatment.

[0003] The existing Chinese patent with the publication number CN116365433B includes a first fixing frame. The first fixing frame is fixedly connected with symmetrically distributed n-shaped fixing frames. Symmetrically distributed n-shaped fixing frames are each rotatably provided with a first arc-shaped plate. The first arc-shaped plate is limited and slidably provided with symmetrically distributed first sliding rods. One end of the first sliding rod is provided with a ball. A first tension spring is fixedly connected between the other end of the first sliding rod and the adjacent first arc-shaped plate. A fixed shell is fixedly connected between parallel first arc-shaped plates through a connecting block. The fixed shell is limited and slidably provided with a second sliding rod. A rotating column is slidably provided on the second sliding rod. A cutting knife is provided on the rotating column through a connecting frame. The fixed shell is provided with an adjusting mechanism for adjusting the cutting knife. The first sliding rod on one group of contact-fitting first arc-shaped plates is provided with a skin rubbing mechanism for pulling the outer skin of the wire. The first fixing frame is provided with a closing mechanism for restricting the swinging of the first arc-shaped plate. The rotating column is provided with a guiding mechanism for switching its working state. By clamping the symmetrically distributed first sliding rods, the cutting knife always cuts the outer skin of the wire at the same depth.

[0004] When the above device is in use, the wire is centered and clamped by symmetrically distributing the first sliding rod, so that the wire to be cut remains straight, which is convenient for the cutting knife to always cut the outer skin of the wire with the same cutting depth, avoiding the cutting knife from cutting through the insulating skin of the wire. However, in the actual use process, after the cutting knife cuts the outer skin of the wire and the outer skin still sleeved on the wire, it is necessary for personnel to manually peel the cut outer skin from the wire, which is time-consuming and laborious, resulting in low wire stripping efficiency. Therefore, it is difficult to automatically strip the cut outer skin from the wire.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting an arc-shaped clamping plate and a conical shell, accurate clamping and guiding of the wire can be achieved. The arc-shaped cutting knife and the longitudinal cutting knife on the inner wall of the arc-shaped clamping plate can perform circumferential cutting and longitudinal cutting on the outer skin of the wire to ensure that the cutting depth is uniform and accurate, and effectively avoid damage to the conductive core inside the wire. Especially when processing medical wires, it can meet its extremely high precision requirements. For example, for medical wires with a diameter of only 0.5 mm, traditional wire stripping methods are prone to damage the wire core, while the clamping mechanism of the present invention can accurately locate the cutting point to ensure the integrity and performance stability of the wire after stripping. In addition, the automatic clamping and releasing functions of the clamping mechanism are realized through the meshing transmission of the first rack and the first gear ring, which further improves the automation and efficiency of the wire stripping process.

[0019] 2. Through the linkage of the circular plate and the pull rod, the moving block can realize horizontal reciprocating movement, thereby driving the clamping mechanism to pull the wire, which not only ensures that the wire remains stable during the stripping process, but also realizes the automatic clamping and release of the clamping mechanism through the ingenious design of the parallelogram groove, avoiding the tedious steps of manual intervention. For example, in continuous production, the wire can be automatically pulled and stripped by the clamping mechanism, which greatly improves the production efficiency. At the same time, the seamless connection between the pulling mechanism and the stripping mechanism enables the outer skin after cutting to be automatically stripped, solving the inefficiency problem of manual stripping in the traditional stripping method, which not only improves the stripping efficiency, but also reduces the risk of uneven stripping or damage to the wire due to manual operation.

[0020] III. Through the reasonable layout of the inverted U-shaped frame, H-shaped frame and support sleeve, the device can provide stable support and guidance for the wire, ensuring the straightness and stability of the wire stripping process. Through the meshing transmission of the second toothed ring and the second rack, the precise movement of the lifting block is realized, so that the lifting blocks and rectangular clamping blocks at both ends of the H-shaped frame can clamp and fix the wire, further enhancing the stability of the wire during the wire stripping process. At the same time, the lifting block drives the V-shaped cutter to cut off the wire, further improving the flatness of the wire section. In addition, the design of the cylindrical rod and L-shaped rod in the stripping mechanism can realize the reset movement of the cylindrical rod through the elastic force of the first spring, ensuring the continuity and reliability of the wire stripping action, improving the stability of the wire stripping device, and is particularly suitable for the high-precision wire stripping requirements of medical wires.

[0021] By using the above-mentioned structure in combination, the problem that in the actual use process of the existing device, after the cutting knife cuts the outer skin of the wire and the outer skin still sleeved on the wire, it is necessary for personnel to manually strip the cut outer skin from the wire, which is time-consuming and laborious, resulting in low wire stripping efficiency, and thus it is difficult to automatically strip the cut outer skin from the wire is solved.

[0037] Embodiment Two:

[0038] On the basis of Embodiment One, furthermore:

[0039] The clamping mechanism includes a cylindrical sleeve 8 that is penetrated and fixedly connected to the fixing plate 7. A conical shell 15 for guiding the end of the wire to pass through the inner wall of the cylindrical sleeve 8 is fixedly connected to the outer contour of the cylindrical sleeve 8 near one end of the support sleeve 5, and an annular plate 9 is fixedly connected to the outer contour of the cylindrical sleeve 8 far from the conical shell 15. Support grooves 901 are opened at symmetric positions on both sides of the annular plate 9, and L-shaped blocks 10 that move reciprocally towards or away from each other are movably connected to the inner walls of the two support grooves 901. Arc-shaped clamping plates 11 for clamping the end of the wire are fixedly connected to the opposite ends of the two L-shaped blocks 10.

[0040] A rotating plate 12 is rotatably connected to the outer contour of the cylindrical sleeve 8 near one end of the annular plate 9. Arc-shaped grooves 121 for pulling the L-shaped blocks 10 to move reciprocally towards or away from each other are opened at symmetric positions on both sides of the rotating plate 12. Movable blocks 14 are fixedly connected to the ends of the two L-shaped blocks 10. The ends of the two movable blocks 14 away from the L-shaped blocks 10 respectively penetrate to the inner walls of the adjacent arc-shaped grooves 121 and are movably connected. A pulling mechanism for driving the arc-shaped clamping plates 11 to clamp and pull the wire is provided on each inverted U-shaped frame 2.

[0041] In use, through the cylindrical sleeve 8 provided on the fixing plate 7 and the conical shell 15 provided on the cylindrical sleeve 8, the cylindrical sleeve 8 can fixedly support the conical shell 15 on the fixing plate 7. And the annular plate 9 provided on the cylindrical sleeve 8 enables the annular plate 9 to be fixedly sleeved on the outer contour of the cylindrical sleeve 8. Through the support groove 901 opened on the annular plate 9 and the L-shaped block 10 provided on the support groove 901, the L-shaped block 10 can be horizontally movably connected under the support of the support groove 901. Through the arc-shaped clamping plate 11 provided on the L-shaped block 10, the arc-shaped clamping plate 11 is fixedly supported on the L-shaped block 10. At the same time, the arc-shaped clamping plate 11 is adapted to the arc-shaped surface of the wire. Through the rotating plate 12 provided on the cylindrical sleeve 8, the rotating plate 12 can be rotatably connected on the outer contour of the cylindrical sleeve 8. Through the arc-shaped groove 121 opened on the rotating plate 12 and the movable block 14 provided on the L-shaped block 10, the movable block 14 can support the position of the L-shaped block 10 under the action of the arc-shaped groove 121. And a pulling mechanism is provided on the inverted U-shaped frame 2, so that the pulling mechanism can drive the arc-shaped clamping plate 11 to clamp one end of the wire and pull it.

[0042] Embodiment 3:

[0043] On the basis of Embodiment 2, further:

[0044] The pulling mechanism includes that one end of the inverted U-shaped frame 2 away from the material tray 3 is penetrated and fixedly connected with a circular plate 20 driven to rotate by a power mechanism. The circular plate 20 is fixedly connected with a pull rod 21 that drives the moving block 6 to move horizontally in a reciprocating manner at a position deviating from the center. And one end of the pull rod 21 away from the circular plate 20 is fixedly connected with the moving block 6 in a rotating manner.

[0045] One end of the moving block 6 close to the fixing plate 7 is penetrated and connected with a first rack 16 that drives the rotating plate 12 to rotate reciprocally in a lifting manner. And a first tooth ring 13 that meshes and drives with the first rack 16 is fixedly connected to the outer contour of the rotating plate 12. A rectangular plate 17 is fixedly connected to the inverted U-shaped frame 2. A parallelogram groove 171 that drives the first rack 16 to move up and down reciprocally is opened on the rectangular plate 17. And a connecting block 18 is fixedly connected to the end of the first rack 16. One end of the connecting block 18 away from the first rack 16 penetrates to the inner wall of the parallelogram groove 171 and is movably connected.

[0046] During use, through the circular plate 20 provided on the inverted U-shaped frame 2, and the circular plate 20 is driven to rotate by the energized motor, so that the motor can drive the circular plate 20 to rotate about a fixed axis on the inverted U-shaped frame 2. Through the pull rod 21 provided on the circular plate 20, both ends of the pull rod 21 are respectively rotatably supported on the moving block 6 and the circular plate 20, and the pull rod 21 is eccentrically placed on the circular plate 20. Along with the circular plate 20 rotating about a fixed axis, the pull rod 21 can pull the moving block 6 to move horizontally back and forth along the inner wall of the moving groove 201 under the action of the circular plate 20.

[0047] Through the first rack 16 provided on the moving block 6, the first rack 16 can be connected to move up and down on the moving block 6. Through the first toothed ring 13 provided on the rotating plate 12, the first toothed ring 13 can be engaged and driven with the teeth on the first rack 16. Through the rectangular plate 17 provided on the inverted U-shaped frame 2, the rectangular plate 17 is fixedly supported on the inverted U-shaped frame 2. Through the connecting block 18 provided on the first rack 16, and the parallelogram groove 171 opened on the rectangular plate 17, the connecting block 18 can be movably supported on the inner wall of the parallelogram groove 171.

[0048] As Figure 6 - Figure 9 shown, and the moving block 6 moves to the extreme position at one end of the moving groove 201 close to the material tray 3. At this time, the arc-shaped clamping plate 11 relatively moves and clamps on the outer contour of one end of the wire. When the pull rod 21 pulls the moving block 6 to move horizontally towards the end close to the circular plate 20, along with the arc-shaped clamping plate 11 clamping the wire, the arc-shaped clamping plate 11 can drive the wire to be pulled synchronously towards the end of the circular plate 20. Then the material tray 3 rotates under the pulling action to release the wire coil. At the same time, the first rack 16 can drive the connecting block 18 to move horizontally along the bottom side of the parallelogram groove 171 in the G direction under the action of the moving block 6. Along with the connecting block 18 moving to the extreme position along the G direction, and the moving block 6 continues to move towards the end close to the circular plate 20, the connecting block 18 can move along the right side of the parallelogram groove 171 to the end extreme position in the D direction, and the connecting block 18 can pull the first rack 16 to move in the upward vertical direction, enabling the first toothed ring 13 to drive the rotating plate 12 to rotate counterclockwise under the action of the first rack 16, and the movable block 14 can drive the L-shaped block 10 to move horizontally in the opposite direction under the action of the arc-shaped groove 121. Thus, the L-shaped block 10 can drive the arc-shaped clamping plate 11 to move in the opposite direction to release the clamping state.

[0049] At this time, the pull rod 21 pushes the moving block 6 to move back towards the end away from the circular plate 20, so that the connecting block 18 can move along the top side of the parallelogram groove 171 in the E direction. When the connecting block 18 moves to the extreme position in the E direction, the conical shell 15 contacts the end of the wire inside the inner wall of the support sleeve 5 and guides the end of the wire to the inner wall of the cylindrical sleeve 8. Along with the pull rod 21 continuing to push the moving block 6 towards the end away from the circular plate 20, the fixing plate 7 can drive the arc-shaped clamping plate 11 to move to the corresponding position of the end of the wire. At the same time, the connecting block 18 moves in the F direction along the left side of the parallelogram groove 171, so that the connecting block 18 can drive the first rack 16 to move downward, and the first toothed ring 13 can drive the rotating plate 12 to rotate clockwise under the action of the first rack 16. Then the movable block 14 can drive the L-shaped blocks 10 on both sides to move relatively under the action of the arc-shaped groove 121. Thus, the L-shaped blocks 10 can push the arc-shaped clamping plate 11 to move relatively and clamp on the outer skin of the wire. Through the cooperation of the above structures, the end of the wire is clamped and pulled.

[0050] An arc-shaped cutting knife 111 for circumferentially cutting the arc-shaped surface of the outer skin of the wire is fixedly connected to the inner wall of each arc-shaped clamping plate 11 near the end of the cylindrical sleeve 8, and a longitudinal cutting knife 112 for longitudinally cutting the outer skin of the wire is fixedly connected to the inner wall of each arc-shaped clamping plate 11.

[0051] When in use, as Figure 2 , Figure 3 and Figure 9 shown, through the arc-shaped cutting knife 111 and the longitudinal cutting knife 112 provided on the arc-shaped clamping plate 11, along with the arc-shaped clamping plate 11 moving relatively and clamping on the outer skin of the wire, the arc-shaped cutting knife 111 can circumferentially cut the outer skin of the end of the wire, and at the same time the longitudinal cutting knife 112 can longitudinally cut the outer skin of the wire, so as to facilitate the subsequent peeling of the outer skin of the wire.

On the opposite surfaces of each rectangular clamping block 35 and the adjacent lifting block 22 on one side, second springs 36 for guiding the rectangular clamping block 35 to move back to its original position are fixedly connected. On the outer contour of one end of each support sleeve 5 close to the material tray 3, a second toothed ring 25 is rotatably connected, which drives the lifting blocks 22 at both ends to move towards or away from each other. On one side of the symmetric positions of the two lifting blocks 22 on each side, a second rack 24 for meshing and driving with the second toothed ring 25 is fixedly connected.

The bottom end of the L-shaped rod 33 is penetrated by the cylindrical rod 28 and movably connected, and on the outer contour of one end of the cylindrical rod 28 close to the support block 30, a stop block 32 in contact with the L-shaped rod 33 is fixedly connected.

[0057] On the outer contour of one end of the cylindrical rod 28 close to the material tray 3, a fixed seat 29 is fixedly connected. On the fixed seat 29, a connecting rod 26 for pushing the lifting blocks 22 to move towards or away from each other in a reciprocating manner is rotatably connected on a fixed axis, and the end of the connecting rod 26 is rotatably connected to the lifting block 22 at the bottom end of the H-shaped frame 4 through a pin shaft.

[0058] When in use, the fixed block 27 provided on the inverted U-shaped frame 2 is fixedly supported on the inverted U-shaped frame 2, and the columnar rod 28 provided on the fixed block 27 is used, and the fixed block 27 movably supports the columnar rod 28, so that the columnar rod 28 can be horizontally movably connected on the fixed block 27, and the support block 30 provided on the columnar rod 28 and the first spring 31 provided on the support block 30 can support the position of the columnar rod 28 under the elastic force of the first spring 31, and the L-shaped rod 33 provided on the moving block 6 and the L-shaped rod 33 is movably sleeved on the columnar rod 28, accompanied by the horizontal reciprocating movement of the moving block 6, so that the moving block 6 can drive the L-shaped rod 33 to move horizontally reciprocatingly on the outer contour of the columnar rod 28.

[0059] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, through the stopper 32 provided on the columnar rod 28, when the moving block 6 drives the L-shaped rod 33 to move horizontally in the direction close to the circular plate 20, the L-shaped rod 33 can move to conflict with the stopper 32, and the stopper 32 can drive the columnar rod 28 to move horizontally in the direction of the circular plate 20 under the push of the L-shaped rod 33, so that the first spring 31 can be squeezed and contracted under the action of the support block 30, and the fixed seat 29 provided on the columnar rod 28, the columnar rod 28 can drive the fixed seat 29 to move in the direction close to the H-shaped frame 4, and through the connecting rod 26 provided on the fixed seat 29, and the two ends of the connecting rod 26 are respectively rotatably supported on the fixed seat 29 and the lifting block 22, the connecting rod 26 can drive the bottom of the H-shaped frame 4 under the push of the fixed seat 29. The lifting block 22 moves in the upward vertical direction, and the second gear ring 25 can drive the lifting block 22 on the top of the H-shaped frame 4 to move in the downward vertical direction under the action of the second rack 24, so that the lifting block 22 can drive the rectangular clamping block 35 to move relatively and clamp on the outer contour of the wire. At the same time, the second spring 36 contracts under the action of the relative movement of the lifting block 22, and the second spring 36 can increase the clamping force of the rectangular clamping block 35 under the action of elastic force. At this time, the wire is in a stationary state, accompanied by the movement of the moving block 6 in the direction close to the circular plate 20, so that the arc clamping plate 11 can drive the cut outer skin to be peeled off from the wire. When the arc clamping plate 11 moves backward to release the clamping state, the outer skin of the inner wall of the arc clamping plate 11 can automatically fall off under the action of gravity.

[0060] When the moving block 6 drives the L-shaped rod 33 to perform horizontal reset movement in a direction away from the circular plate 20, the above structure simultaneously performs reset movement in the opposite direction.

[0061] Embodiment five:

[0062] On the basis of Embodiment 4, furthermore:

[0063] On the opposite surfaces of the two lifting blocks 22 on each side, at the ends far away from the second rack 24, there are fixedly connected V-shaped cutters 23 for cutting the wire.

[0064] During use, when the lifting block 22 drives the second toothed ring 25 to move relatively to clamp and fix the wire, through the V-shaped cutter 23 provided on the lifting block 22, at this time the lifting block 22 can drive the V-shaped cutter 23 to contact the surface of the wire, and the wire is in a stationary state. As the lifting block 22 drives the V-shaped cutter 23 to continue to move relatively, the V-shaped cutter 23 can cut off the wire, further improving the flatness of the wire section.

[0065] It is further realized that in the actual use process of the existing device, the outer skin after cutting can be automatically peeled off from the wire, which is convenient to use and better than traditional products.

[0066] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed without doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.
