Description

Technical Field

[0001] This invention relates to the field of medical guidewire processing machinery and equipment, specifically to an adaptive clamping multifunctional guidewire high-precision coating dip-coating mechanism. Background Technology

[0002] Existing traditional medical interventional guidewire coating and dipping equipment mostly adopts a single-station, single-machine processing mode, which can only complete the intermittent dipping and coating of a single guidewire at a time. It cannot be equipped with multiple sets of tooling to simultaneously complete the continuous processing of multiple guidewires. During the workpiece loading and unloading stage, the entire machine needs to be stopped and the wires are threaded manually, which is difficult to meet the needs of large-scale continuous production. The overall effective production efficiency of the equipment is low. At the same time, the existing equipment is not equipped with an adaptive clamping and correction mechanism that can be triggered by the power of the conveyor movement. The guidewire lacks a centering limit constraint throughout the entire process of conveying and flowing with the tooling, which is prone to problems such as horizontal deviation and radial tilt. This directly causes a large coaxiality deviation between the guidewire and the center axis of the coating cylinder. When the guidewire is immersed in the coating liquid, the force is uneven. After dipping and coating, the thickness of the surface lubricating coating varies greatly and the uniformity is poor. The coating thickness accuracy is difficult to meet the high standard production requirements of medical guidewires.

[0003] Traditional equipment requires separate drive motors, solenoid valves, and other components for cleaning the liquid accumulation at the bottom of the limit sleeve and replenishing the coating liquid in the coating cylinder. This significantly increases the number of mechanical parts and electrical control circuits, complicating the assembly process and raising both manufacturing and maintenance costs. The coordinated operation of multiple drive components also increases the overall failure rate. Furthermore, relying on solenoid valves to control the liquid flow can cause frequent fluctuations in the coating liquid level inside the coating cylinder, further exacerbating uneven coating thickness and localized missed coating defects. In addition, conventional equipment lacks a station-level self-locking protection design for the lifting drive components. During tooling transport, the lifting rod is susceptible to vibration and external interference, leading to unexpected lifting and lowering. The immersion depth of the guide wire cannot be stably controlled, resulting in frequent over-coating, under-coating, and missed coating defects. The fixed and non-adjustable downward lifting stroke only adapts to a single length of guide wire, failing to flexibly switch between various workpiece specifications. The equipment lacks universal adaptability and suffers from multiple technical defects, including low mass production efficiency, poor coating accuracy, narrow adaptability, complex structure prone to failure, and high production and maintenance costs.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs an adaptive clamping multifunctional guide wire high-precision coating dip-coating mechanism, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to provide a multifunctional adaptive straightening guide wire high-precision coating dip-coating mechanism that enables simultaneous processing of multiple guide wires, adaptive clamping and positioning during transport, workstation linkage cleaning and replenishment, self-locking of the lifting mechanism and adjustable guide wire stroke, stable dip-coating liquid level, and improved coating uniformity and continuous production efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution: This invention provides an adaptive clamping multifunctional guide wire high-precision coating dipping mechanism, comprising a bracket, a chassis, a replenishment tank, a water pump, an dipping tank, and a support frame, as well as a conveying mechanism, a lifting mechanism, and a coating cylinder. The chassis is fixedly installed between the brackets, and the replenishment tank and dipping tank are fixedly installed on top of the chassis. The dipping tank is located on the side of the replenishment tank, and the dipping tank and replenishment tank are connected by a water pump. Support frames are installed on both sides of the bracket, and a horizontal plate on top of the support frame is fixed to the crossbeam of the bracket. A conveying mechanism is fixedly installed above the horizontal plate, and two sets of conveying mechanisms are provided. The mechanism is equipped with a lifting mechanism that can be carried along; the conveying mechanism is equipped with a fixed belt and a limiting belt that operate synchronously. The fixed belt is equipped with a clamping plate with a spring-loaded reset structure. The limiting belt is equipped with a limiting plate to limit the horizontal movement of the lifting mechanism. The inner side of the limiting frame is equipped with a gradually thickening convex plate. During conveying, the convex plate and the clamping plate automatically retract and lock the lifting mechanism. After the conveying is disengaged, the spring-loaded clamping plate automatically releases the clamp. The coating cylinders are arranged in an array in the immersion tank. The coating cylinders rely on the mechanical thrust generated by the horizontal movement of the lifting mechanism to synchronously complete the wiping of the liquid accumulation at the bottom of the limiting sleeve and the on / off control of the liquid inlet tank in the coating cylinder.

[0007] Preferably, the conveying mechanism includes a limiting frame, a rotating cylinder, a fixing belt, and a limiting belt. The limiting frame is fixedly installed on the horizontal plate. The limiting frame has a U-shaped cross-section. Rotating cylinders are installed at both ends inside the limiting frame. A conveying motor is coaxially installed on one of the rotating cylinders. A protruding plate is fixedly installed on the side of the limiting frame near the conveying motor. Small teeth and large teeth are fixedly installed on the rotating cylinder. The small teeth are near the conveying motor. A fixing belt is installed on the two small teeth. A fixing groove is arrayed on the fixing belt. A limiting belt is installed on the two large teeth. Limiting holes are arrayed on the side of the limiting belt near the fixing belt. A limiting plate is fixedly installed on the limiting belt.

[0008] The conveyor motor drives the rotating drum to rotate. The one-piece molded small toothed part and large toothed part drive the fixed belt and the limiting belt to operate synchronously. The U-shaped limiting frame restricts the left and right deviation of the conveyor belt. The fixed belt is equipped with a clamping component and moves synchronously. The limiting belt's upper plate fits against the sliding block to restrict the horizontal displacement of the lifting mechanism.

[0009] Preferably, a positioning cylinder is fixedly installed inside the fixing groove, a clamping plate is fixedly installed at the upper end of the positioning cylinder, one end of the L-link is fixed to the upper surface of the clamping plate, and the other end of the L-link is fixed in the limiting hole. The clamping plate has an array of guide grooves, a guide slider is slidably installed inside the guide grooves, a clamping block is fixedly installed above the guide slider, a sliding cylinder is fixedly installed below the guide slider, a rotating disk is rotatably installed below the clamping plate, an arc-shaped groove is arrayed on the rotating disk, the sliding cylinder slides inside the arc-shaped groove, one end of the spring is installed inside the rotating disk, the other end of the spring is fixedly installed on the positioning cylinder, and a pressing rod is fixedly installed on the side of the rotating disk, the pressing rod corresponding to the protrusion on the inner side of the limiting frame.

[0010] The L-link drives the clamping plate to move synchronously with the conveyor belt. During the conveying process, the thickness of the trapezoidal convex plate gradually increases, pushing and squeezing the rod, driving the rotating plate to rotate and pulling the clamping block towards the center through the arc groove to clamp the lifting mechanism. The thickness of the convex plate in the middle section is constant to maintain a stable clamping force. After reaching the section where the convex plate is thinned, the pushing force decreases, the spring releases the stored energy to drive the rotating plate to reverse and the clamping block to automatically release.

[0011] Preferably, the fixed plate in the lifting mechanism is located above the limiting band, and sliding blocks are fixedly installed on both sides of the fixed plate. The sliding blocks are located on the limiting band, and the sides of the sliding blocks are in close contact with the limiting plate. A lifting ring is fixedly installed above the sliding block, and a limiting post and a pressing block are fixedly installed below the sliding block. The limiting post corresponds to the center position of the clamping plate, and the two sides of the pressing block are chamfered.

[0012] The entire lifting mechanism is hoisted onto the limiting belt by hooking the lifting ring. The sliding block is attached to the limiting plate to achieve horizontal limiting. The limiting column is placed in the center of the clamping plate to complete vertical positioning. During conveying, the bottom chamfered pressing block continuously squeezes the structure below to output vertical driving force. After processing, the lifting mechanism with pre-installed guide wire can be lifted off as a whole by the lifting ring.

[0013] Preferably, the fixed plate has an internal array of rotating gears, a limit cylinder is fixedly mounted on the upper surface of the fixed plate, a sliding sleeve is fixedly mounted on the lower surface of the fixed plate, a lifting cylinder slides vertically on the sliding sleeve, a rack is mounted on the side of the lifting cylinder, and the central axes of the rotating gears, limit cylinders, sliding sleeves and lifting cylinders coincide. A lifting rod passes through the rotating gears, limit cylinders, sliding sleeves and lifting cylinders, and the rotating gears rotate to drive the lifting rod to rise and fall.

[0014] The worm gear drives all the rotating gears to rotate synchronously. The gears mesh with the rack on the outside of the lifting cylinder, driving the lifting cylinder to slide vertically along the limiting cylinder and the sliding sleeve. The lifting rod, which is coaxially inserted, moves up and down synchronously, causing the guide wire to be immersed in and lifted out of the coating liquid.

[0015] Preferably, a fixing cylinder is fixedly installed on the side of the fixing plate, and a worm gear is rotatably installed inside the fixing cylinder. The worm gear meshes with the rotating gear. One end of the worm gear is connected to the output shaft of the lifting motor. A sliding groove is arrayed inside the fixing cylinder near the lifting motor. A compression spring is engaged inside the sliding groove. A fixing block is engaged at the other end of the compression spring. The fixing block slides inside the sliding groove. A cross groove is formed inside the worm gear near the lifting motor. The four grooves of the cross groove correspond to the sliding groove. A cross block is slidably installed inside the cross groove. A return spring is engaged at the end of the cross block away from the lifting motor. The other end of the return spring is engaged inside the worm gear. A compression cylinder is fixedly installed at the other end of the cross block. One outer end of the compression cylinder is chamfered. Four limiting blocks are fixedly installed at the end of the worm gear near the lifting motor. A protrusion is fixedly connected to the end of the output shaft of the lifting motor. A gap is formed between the limiting blocks to allow the protrusion to slide.

[0016] When the lifting mechanism reaches the coating station, the fixed plate squeezes the extrusion cylinder and pushes the cross block inward. The fixed block disengages from the cross groove to unlock the worm gear. The motor protrusion is embedded in the gap of the limit block to transmit torque and drive the lifting and dipping coating. After leaving the station, the extrusion pressure disappears, the recovery spring pushes the cross block to reset, and the fixed block is locked into the cross groove to lock the worm gear.

[0017] Preferably, adjusting blocks and supporting blocks are fixedly installed on both sides below the fixed cylinder and the fixed plate. The adjusting block has an adjusting groove inside, and an adjusting spring is engaged inside the adjusting groove. The other end of the adjusting spring is engaged with a locking block. A rotating rod is rotatably installed between the adjusting block and the supporting block. Adjusting gears are arranged in an array on the rotating rod. The adjusting gears mesh with the rack on the lifting cylinder. The side of the rotating rod near the adjusting block has a locking groove in an array. The locking blocks correspond to the locking grooves. A detachable handle is fitted to the end of the rotating rod with the locking groove. A cylinder is fixedly installed at the end of the handle near the rotating rod. Blocks are arranged in an array inside the cylinder, and the blocks inside the cylinder correspond to the locking grooves. The end of the cylinder and the locking blocks are provided with matching chamfer structures.

[0018] Disassembling and rotating the handle will cause the rotating rod and adjusting gear to rotate, changing the meshing position of the adjusting gear and rack to adjust the maximum upward stroke of the lifting rod. After adjustment, the adjusting spring pushes the locking block into the locking groove to lock the rotating rod. The adjusting gear assists in the transmission of the lifting cylinder. The handle can quickly adjust the lifting depth and is detachable to avoid movement interference. The spring locking structure ensures long-term stability of the adjustment stroke. It can be adapted to guide wires of different lengths without disassembling the equipment, thus broadening the applicability of the equipment.

[0019] Preferably, the coating cylinder array is located inside the immersion tank. Each coating cylinder has a liquid inlet groove on its side. The coating cylinders are arranged horizontally inside the immersion tank and vertically aligned with the lifting rod. A limit sleeve is installed above each coating cylinder. A cleaning block is fixedly installed on the side of each coating cylinder. A drive gear is installed inside the cleaning block, and a driven gear is meshed on the side of the drive gear. A cleaning rod is fixedly installed on the driven gear. The cleaning rod is used to clean the lower surface of the limit sleeve. A cleaning cylinder is inserted through the cleaning block and the drive gear. A sealing block is fixedly installed at the lower end of each cleaning cylinder. The sealing block corresponds to the liquid inlet groove and forms a sealing fit with the liquid inlet groove.

[0020] When the cleaning cylinder moves down, the sealing block disengages from the liquid inlet tank to allow for liquid replenishment. At the same time, the gear drives the cleaning rod to wipe the liquid accumulated at the bottom of the limiting sleeve. After the lifting mechanism leaves the work position, the cleaning cylinder moves up, the sealing block blocks the liquid inlet tank, and the cleaning rod rotates back to reset. The coating cylinder and the limiting sleeve constrain the guide wire's immersion trajectory. The lifting and lowering of the cleaning cylinder synchronously controls the liquid flow and cleaning action.

[0021] Preferably, a crossbar is fixedly installed on the cleaning cylinder, and a pressing rod is fixedly assembled at both ends of the crossbar. A pressing plate is fixedly installed at the upper end of the pressing rod, and a squeezing block is fixedly assembled on the upper side of both ends of the pressing plate. The cross-sectional shape of the squeezing block is T-shaped, and the top two sides of the squeezing block are arc-shaped. The arc-shaped structure is adapted to fit the chamfer of the pressing plate. A pressing spring is arrayed and snapped onto the lower end of the pressing plate, and the other end of the pressing spring is snapped onto the crossbar.

[0022] During conveying, the chamfered pressing block of the sliding block horizontally presses the T-shaped pressing block, converting the horizontal thrust into downward pressure to drive the crossbar and cleaning cylinder downward. After the workpiece leaves the pressing area, the pressing spring rebounds, driving the entire cleaning and replenishing structure to reset. This inclined force conversion structure stably reuses the conveying power to drive the vertical cleaning and replenishing actions. The rapid rebound of the pressing spring ensures that the mechanism resets without lag. The arc-shaped fitting structure runs smoothly with minimal wear, ensuring stable and reliable linkage action for each set of workpieces.

[0023] The beneficial effects of this invention are as follows: 1. The equipment adopts a synchronous transmission fixed belt and limit belt to carry multiple sets of lifting mechanisms that can be hoisted as a whole. The lifting mechanism can be pre-installed with guide wires offline. During processing, multiple guide wires are synchronously conveyed and dip-coated. After processing, the lifting mechanism that has pre-installed the workpiece can be directly hoisted and replaced without stopping the machine to wait for material to be loaded, which greatly improves the continuous production capacity of the equipment.

[0024] 2. Relying on the conveyor's propulsion power and the trapezoidal convex plate to drive the clamping disc to automatically retract, the lifting rod and coating cylinder are automatically corrected for coaxiality throughout the conveying process to avoid guide wire deviation and tilting; the clamping mechanism has a built-in spring for energy storage, and automatically releases the clamp after the extrusion is released, eliminating the need for an additional clamping motor, with a simple and energy-saving structure, and eliminating the defect of uneven coating thickness caused by guide wire dip coating deviation from the positioning level.

[0025] 3. The horizontal movement of the reusable conveyor mechanism synchronously drives the cleaning and liquid circuit switching actions, eliminating the need for an additional independent cleaning motor and liquid replenishment solenoid valve. When the workpiece moves to the processing area, the liquid replenishment is automatically activated and the liquid accumulation at the bottom of the limiting sleeve is wiped off. After leaving the workstation, the liquid inlet is automatically closed and the cleaning rod is reset. This not only maintains a uniform liquid level in each coating cylinder and suppresses liquid level fluctuations, but also eliminates the thickening of the guide wire coating and particle defects caused by the dripping of liquid from the limiting sleeve, ensuring high coating precision.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. The embodiments described below 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.

[0030] This invention provides, for example Figure 1 , 2 As shown in figures 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17, the present invention provides an adaptive clamping multifunctional guide wire high-precision coating dipping mechanism, comprising a support 1, a chassis 11, a replenishment tank 2, a water pump 4, an immersion tank 3, and a support frame 5, and further comprising a conveying mechanism 6, a lifting mechanism 7, and a coating cylinder 8. The chassis 11 is fixedly installed between the supports 1, and the replenishment tank 2 and the immersion tank 3 are fixedly installed above the chassis 11. The immersion tank 3 is located on the side of the replenishment tank 2, and the immersion tank 3 and the replenishment tank 2 are connected by the water pump 4. Support frames 5 are installed on both sides of the support 1, and a horizontal plate 51 above the support frame 5 is fixed to the crossbeam of the support 1. A [missing information - likely a device or structure] is fixedly installed above the horizontal plate 51. The system is equipped with a conveying mechanism 6, and a lifting mechanism 7 that can follow the conveyor is mounted between two sets of conveying mechanisms 6. The conveying mechanism 6 is equipped with a fixed belt 64 and a limiting belt 65 that operate synchronously. The fixed belt 64 is equipped with a clamping plate 661 with a spring 668 reset structure. The limiting belt 65 is equipped with a limiting plate 652 to limit the horizontal movement of the lifting mechanism 7. The inner side of the limiting frame 61 is provided with a gradually thickening convex plate 611. During conveying, the convex plate 611 and the clamping plate 661 automatically retract and lock the lifting mechanism 7. After the conveyor is released, the spring 668 drives the clamping plate 661 to automatically release. The immersion tank 3 is arranged in an array of coating cylinders 8. The coating cylinders 8 rely on the mechanical thrust generated by the horizontal movement of the lifting mechanism 7 to synchronously complete the wiping of the liquid accumulation at the bottom of the limiting sleeve 82 and the on / off control of the liquid inlet tank 81 in the coating cylinder 8.

[0031] like Figure 1 , 2As shown in Figure 3, the conveying mechanism 6 includes a limiting frame 61, a rotating cylinder 62, a fixing belt 64, and a limiting belt 65. The limiting frame 61 is fixedly installed on the horizontal plate 51. The cross-sectional shape of the limiting frame 61 is U-shaped. Rotating cylinders 62 are installed at both ends inside the limiting frame 61. A conveying motor 63 is coaxially installed on one of the rotating cylinders 62. A protruding plate 611 is fixedly installed on the side of the limiting frame 61 near the conveying motor 63. Small teeth 621 and large teeth 622 are fixedly installed on the rotating cylinder 62. The small teeth 621 are near the side of the conveying motor 63. A fixing belt 64 is installed on the two small teeth 621. Fixing grooves 641 are arranged in an array on the fixing belt 64. A limiting belt 65 is installed on the two large teeth 622. Limiting holes 651 are arranged in an array on the side of the limiting belt 65 near the fixing belt 64. Limiting plates 652 are fixedly installed in an array on the limiting belt 65.

[0032] The conveyor motor 63 is started, driving the rotating cylinders 62 at both ends to rotate synchronously. The small toothed part 621 and the large toothed part 622 respectively drive the fixed belt 64 and the limiting belt 65 to move forward at high speed. The fixed belt 64 drives the clamping plate 661 through the positioning cylinder 66 and the L-link 662, and the lifting mechanism 7 moves synchronously. During the conveying process, the thickness of the convex plate 611 gradually increases, squeezing the squeezing rod 669, driving the rotating plate 667 to rotate. The clamping block 665 synchronously retracts towards the center to hug the limiting column 722, locking the lifting mechanism 7, correcting the coaxiality of the lifting rod 73 and the limiting sleeve 82, and the spring 668 rotates synchronously to store energy.

[0033] like Figure 1 , 2 As shown in Figures 4, 5, 6, and 7, a positioning cylinder 66 is fixedly installed inside the fixing groove 641. A clamping plate 661 is fixedly installed at the upper end of the positioning cylinder 66. One end of the L-connecting rod 662 is fixed to the upper surface of the clamping plate 661, and the other end of the L-connecting rod 662 is fixed in the limiting hole 651. Guide grooves 663 are arrayed on the clamping plate 661. A guide slider 664 is slidably installed inside the guide grooves 663. A clamping block 665 is fixedly installed above the guide slider 664. A sliding cylinder 666 is fixedly installed below the clamping plate 661, and a rotating disk 667 is rotatably installed below the clamping disk 661. The rotating disk 667 has an array of arc-shaped grooves 6671. The sliding cylinder 666 slides inside the arc-shaped grooves 6671. One end of the spring 668 is installed inside the rotating disk 667, and the other end of the spring 668 is fixedly installed on the positioning cylinder 66. A pressing rod 669 is fixedly installed on the side of the rotating disk 667. The pressing rod 669 corresponds to the protrusion 611 on the inner side of the limiting frame 61.

[0034] L-link 662 drives clamping disc 661 to move synchronously with the conveyor belt. During the conveying process, the thickness of trapezoidal convex plate 611 gradually increases, pushing and squeezing rod 669, driving rotating disc 667 to rotate and pulling clamping block 665 towards the center through arc groove 6671 to clamp lifting mechanism 7. The thickness of convex plate 611 in the middle section is constant to maintain a stable clamping force. After reaching the section where convex plate 611 is thinned, the pushing force decreases, and spring 668 releases stored energy to drive rotating disc 667 to reverse and clamping block 665 to automatically release.

[0035] like Figure 8 and 9 As shown, the fixed plate 71 in the lifting mechanism 7 is located above the limiting band 65. Sliding blocks 72 are fixedly installed on both sides of the fixed plate 71. The sliding blocks 72 are located on the limiting band 65, and the side of the sliding blocks 72 is in close contact with the limiting plate 652. A lifting ring 721 is fixedly installed above the sliding block 72. A limiting post 722 and a pressing block 723 are fixedly installed below the sliding block 72. The limiting post 722 corresponds to the center position of the clamping plate 661. The two sides of the pressing block 723 are chamfered.

[0036] The entire lifting mechanism 7 is hoisted and placed above the limiting band 65 by hooking the lifting ring 721 with an external hook; the side of the sliding block 72 is attached to the limiting plate 652 to complete the horizontal limiting, and the limiting post 722 at the bottom of the sliding block 72 abuts into the center of the clamping plate 661 to achieve vertical positioning; during the conveying process, the chamfered pressing block 723 at the bottom of the sliding block 72 continuously presses down on the linkage component below, outputting vertical driving power; after a batch of processing is completed, the lifting mechanism 7 can be lifted off the whole again with the hook and replaced with a spare lifting mechanism 7 with a pre-installed guide wire.

[0037] like Figure 1 , 8 As shown in Figure 11, the fixed plate 71 has an array of rotating gears 711 inside, a limit cylinder 712 fixedly mounted on the upper surface of the fixed plate 71, a sliding sleeve 713 fixedly mounted on the lower surface of the fixed plate 71, a lifting cylinder 714 vertically sliding on the sliding sleeve 713, a rack 715 mounted on the side of the lifting cylinder 714, and the central axes of the rotating gears 711, the limit cylinders 712, the sliding sleeves 713 and the lifting cylinder 714 coincide. A lifting rod 73 passes through the rotating gears 711, the limit cylinders 712, the sliding sleeves 713 and the lifting cylinder 714, and the rotating gears 711 rotate to drive the lifting rod 73 to rise and fall.

[0038] When the lifting motor 76 is started to rotate in the forward direction, the worm gear 75 meshes with the rotating gear 711 arranged in an array inside the fixed plate 71 for transmission. The rotating gear 711 works in sync with the adjusting gear 791 on the rotating rod 79 that meshes with the rack 715 of the lifting cylinder 714. The limiting cylinder 712, the sliding sleeve 713, and the lifting cylinder 714 are coaxially arranged, and the lifting rod 73 passes through the three of them. Driven by the gear and rack 715, it slides vertically downward, driving the clamped and fixed guide wire to pass through the limiting sleeve 82 above the coating cylinder 8 and be completely immersed in the coating liquid inside the coating cylinder 8 to complete the dipping process. The operator can remove and install the handle 793 at the outer end of the rotating rod 79. By rotating the handle 793, the angle of the rotating rod 79 can be adjusted. The adjusting spring 772 in the adjusting block 77 pushes the locking block 773 to engage with the locking groove 792 of the rotating rod 79 to lock the angle. This allows for fine adjustment of the lifting stroke of the lifting rod 73 to adapt to the processing needs of guide wires of different lengths and specifications.

[0039] like Figure 1 , 9 As shown in Figures 10, 11, 12, and 13, a fixing cylinder 74 is fixedly installed on the side of the fixing plate 71. A worm gear 75 is rotatably installed inside the fixing cylinder 74. The worm gear 75 meshes with the rotating gear 711. One end of the worm gear 75 is connected to the output shaft of the lifting motor 76. A sliding groove 741 is arrayed inside the fixing cylinder 74 near the lifting motor 76. A compression spring 742 is engaged inside the sliding groove 741. A fixing block 743 is engaged at the other end of the compression spring 742. The fixing block 743 slides inside the sliding groove 741. A cross groove is formed inside the worm gear 75 near the lifting motor 76. 751, the four grooves of the cross groove 751 correspond to the sliding groove 741. A cross block 752 is slidably installed inside the cross groove 751. A return spring 753 is engaged at the end of the cross block 752 away from the lifting motor 76. The other end of the return spring 753 is engaged inside the worm gear 75. A compression cylinder 754 is fixedly installed at the other end of the cross block 752. One end of the compression cylinder 754 is chamfered. Four limiting blocks 755 are fixedly installed at the end of the worm gear 75 near the lifting motor 76. A protrusion 761 is fixedly connected to the end of the output shaft of the lifting motor 76. A gap is formed between the limiting blocks 755 to allow the protrusion 761 to slide.

[0040] When the lifting mechanism 7 moves with the conveying mechanism 6 to the dipping station directly above the coating cylinder 8, the output shaft protrusion 761 of the lifting motor 76 is inserted into the gap of the end limit block 755 of the worm 75 and transmits torque; at the same time, the side of the fixing plate 71 presses the extrusion cylinder 754 on the end face of the worm 75, and the extrusion cylinder 754 pushes the cross block 752 to slide inward along the cross groove 751 to compress the recovery spring 753. The cross block 752 pushes the fixing block 743 in the sliding groove 741 outward and away from the cross groove 751, releasing the rotation lock state of the worm 75. When the lifting motor 76 is started to rotate in the forward direction, the worm gear 75 engages with and drives all the rotating gears 711 inside the fixed plate 71 to rotate synchronously. The rotating gears 711 cooperate with the adjusting gear 791 on the rotating rod 79 and the rack 715 of the lifting cylinder 714 to drive the lifting cylinder 714 and the lifting rod 73 to slide vertically downward. The guide wire fixed at the bottom of the lifting rod 73 passes through the limiting sleeve 82 and is completely immersed in the coating liquid inside the coating cylinder 8, completing the immersion coating process for the preset time.

[0041] like Figure 10 , 12 As shown in Figure 14, adjusting blocks 77 and supporting blocks 78 are fixedly installed on both sides below the fixed cylinder 74 and the fixed plate 71. The adjusting block 77 has an adjusting groove 771 inside, and an adjusting spring 772 is engaged inside the adjusting groove 771. A engaging block 773 is engaged at the other end of the adjusting spring 772. A rotating rod 79 is rotatably mounted between the adjusting block 77 and the supporting block 78. Adjusting gears 791 are arrayed on the rotating rod 79, and the adjusting gears 791 interact with the rack 715 on the lifting cylinder 714. The rotating rod 79 has a locking groove 792 arrayed on one side near the adjusting block 77. The locking block 773 corresponds to the locking groove 792. The end of the rotating rod 79 with the locking groove 792 is equipped with a detachable handle 793. A cylinder 794 is fixedly installed on the end of the handle 793 near the rotating rod 79. Blocks are arrayed inside the cylinder 794, and the blocks inside the cylinder 794 correspond to the locking groove 792. The end of the cylinder 794 and the locking block 773 are provided with matching chamfer structures.

[0042] Disassembling the handle 793 and rotating it can drive the rotating rod 79 and the adjusting gear 791 to rotate, changing the meshing position of the adjusting gear 791 and the rack 715 to adjust the maximum upward stroke of the lifting rod 73. After adjustment, the adjusting spring 772 pushes the locking block 773 to lock into the locking groove 792 to lock the rotating rod 79. The adjusting gear 791 assists in the transmission of the lifting cylinder 714. The handle 793 can quickly adjust the lifting depth and is detachable to avoid motion interference. The spring locking structure ensures long-term stability of the adjustment stroke. It can be adapted to guide wires of different lengths without disassembling the equipment, thus broadening the applicability of the equipment.

[0043] like Figure 1 , 2As shown in Figures 15, 16, and 17, the coating cylinders 8 are arrayed inside the immersion tank 3. An inlet groove 81 is provided on the side of each coating cylinder 8. The coating cylinders 8 are arranged horizontally inside the immersion tank 3, and are vertically aligned with the lifting rod 73. A limiting sleeve 82 is installed above each coating cylinder 8. A cleaning block 83 is fixedly installed on the side of each coating cylinder 8. A drive gear 831 is installed inside the cleaning block 83. A driven gear 832 is meshed on the side of the drive gear 831. A cleaning rod 833 is fixedly installed on the driven gear 832. The cleaning rod 833 is used to clean the lower surface of the limiting sleeve 82. A cleaning cylinder 84 is provided through the cleaning block 83 and the drive gear 831. A sealing block 85 is fixedly installed at the lower end of the cleaning cylinder 84. The sealing block 85 corresponds to the inlet groove 81, and the sealing block 85 can form a sealing fit with the inlet groove 81.

[0044] The cleaning cylinder 84 performs two actions simultaneously as it descends: First, the driving gear 831 and driven gear 832 meshing with each other inside the cleaning block 83 on the side of the cleaning cylinder 84 generate transmission as the cleaning cylinder 84 descends. The driven gear 832 drives the cleaning rod 833 to rotate and wipe around the lower surface of the limiting sleeve 82, removing residual coating liquid at the bottom of the limiting sleeve 82 in real time, preventing coating accumulation that could lead to uneven coating thickness. Second, the sealing block 85 at the bottom of the cleaning cylinder 84 moves down and disengages from the liquid inlet groove 81 on the side wall of the coating cylinder 8. The liquid inlet groove 81 is now fully open, and the water pump 4 on the chassis 11 of the support 1 continuously draws coating liquid from the replenishment tank 2 and delivers it to the immersion tank 3. The coating liquid flows through the liquid inlet groove 81 into the horizontally arranged coating cylinders 8 in the immersion tank 3, pre-storing sufficient coating liquid. The water pump 4 continuously circulates and replenishes the liquid to ensure that the liquid level in all coating cylinders 8 is consistent, providing stable liquid level conditions for high-precision coating.

[0045] like Figure 1 , 2 As shown in Figures 16 and 17, a crossbar 86 is fixedly installed on the cleaning cylinder 84. A pressing rod 87 is fixedly assembled at both ends of the crossbar 86. A pressing plate 871 is fixedly installed at the upper end of the pressing rod 87. A squeezing block 872 is fixedly assembled on the upper side of both ends of the pressing plate 871. The cross-sectional shape of the squeezing block 872 is T-shaped, and the top two sides of the squeezing block 872 are arc-shaped. The arc-shaped structure is adapted to fit the chamfer of the pressing plate 871. A pressing spring 873 is arrayed and snapped onto the lower end of the pressing plate 871. The other end of the pressing spring 873 is snapped onto the cross plate 51.

[0046] When the sliding block 72 moves synchronously with the limiting band 65, the chamfered pressing blocks 723 on both sides of the sliding block 72 move forward synchronously and continuously press down on the upper squeezing block 872. The arc-shaped surface of the top of the squeezing block 872 fits against the chamfer at the lower end of the pressing plate 871, converting the horizontal thrust into vertical downward pressure. This causes the pressing plate 871 to compress the bottom pressing spring 873 and drive the two side pressing rods 87 to move down synchronously. The horizontal bar 86 connected to the bottom of the pressing rod 87 moves down synchronously, driving the centrally penetrating cleaning cylinder 84 to descend vertically.

[0047] During operation, the operator uses an external hook to hook the top ring 721 of the sliding block 72, hoisting the entire lifting mechanism 7 above the two parallel limiting bands 65. The sliding block 72 is then slightly adjusted laterally to ensure that its side is tightly against the limiting plate 652, thus preventing horizontal deviation of the lifting mechanism 7 during transport. The fixing plate 71 is then lowered, and the bottom limiting post 722 of the sliding block 72 is inserted into the center of the clamping plate 661 for positioning. Multiple guide wires to be processed are manually inserted into the interior of each set of lifting rods 73 for fixation. The external hook is then removed, and the entire lifting mechanism 7 is supported by the fixing band 64 and the limiting band 65.

[0048] Start the conveyor motor 63, which drives the rotating drums 62 at both ends to rotate synchronously. The small toothed part 621 drives the fixed belt 64 and the large toothed part 622 synchronously drives the limiting belt 65. The two convey forward at the same linear speed. The fixed belt 64 drives the clamping plate 661 through the positioning cylinder 66 and the L-link 662. The clamping plate 661 lifts the lifting mechanism 7 and moves synchronously, realizing the synchronous and continuous conveying and processing of multiple guide wires, which greatly improves the production capacity.

[0049] The conveying mechanism 6 drives the lifting mechanism 7 to move forward continuously. The thickness of the inner convex plate 611 of the limiting frame 61 gradually increases, continuously squeezing the end of the outer squeezing rod 669 of the rotating disk 667, pushing the rotating disk 667 to rotate circumferentially. The arc groove 6671 of the rotating disk 667 pulls the sliding cylinder 666 to slide radially towards the center along the guide groove 663 of the clamping disk 661. The multiple sets of clamping blocks 665 on the top of the guide slider 664 simultaneously retract and hug the limiting post 722, locking and positioning the lifting mechanism 7. The coaxiality of the lifting rod 73 and the limiting sleeve 82 of the coating cylinder 8 is automatically corrected to avoid the guide wire coating deviation caused by the conveying offset. During the rotation of the rotating disk 667, the spring 668 is compressed to store energy, providing power for subsequent clamping and reset.

[0050] As the sliding block 72 moves forward with the limiting band 65, the chamfered pressing block 723 at the bottom continuously presses down on the squeezing block 872. The arc-shaped surface at the top of the squeezing block 872 fits against the chamfer of the pressing plate 871, converting the horizontal thrust into vertical downward pressure, compressing the pressing spring 873 and causing the pressing rod 87, the crossbar 86, and the cleaning cylinder 84 to move downward simultaneously: ① The downward movement of the cleaning cylinder 84 causes the driving gear 831 and the driven gear 832 inside the cleaning block 83 to mesh and transmit power. The driven gear 832 drives the cleaning rod 833 to surround the limiting sleeve 82 (see table below). ① The rotating wipe removes the accumulated coating liquid at the bottom of the limiting sleeve 82 in real time, eliminating the uneven coating thickness defect caused by the dripping liquid. ② The bottom sealing block 85 of the cleaning cylinder 84 moves down synchronously to disengage from the liquid inlet groove 81 on the side wall of the coating cylinder 8, and the liquid inlet groove 81 is fully open. The water pump 4 continuously draws coating liquid from the replenishment tank 2 and delivers it to the immersion tank 3. The coating liquid flows into the coating cylinder 8 through the liquid inlet groove 81, stabilizing the reserve of coating liquid in advance. The water pump 4 continuously circulates and replenishes the liquid to ensure that the liquid level of all coating cylinders 8 is uniform, providing constant liquid level conditions for high-precision immersion coating. When the sliding block 72 moves to the position where it is disengaged from the squeezing block 872, the pressing spring 873 rebounds and pulls the pressing plate 871, the pressing rod 87, and the cleaning cylinder 84 to move upward as a whole: the sealing block 85 re-seals the liquid inlet groove 81, blocking the continuous flow of coating liquid and avoiding violent fluctuations in the liquid level when the guide wire is immersed; at the same time, the upward movement of the cleaning cylinder 84 drives the gear to reverse the transmission, and the cleaning rod 833 rotates back to reset, waiting for the next wiping operation.

[0051] When the lifting mechanism 7 moves with the conveying mechanism 6 to the dipping station directly above the coating cylinder 8, the output shaft protrusion 761 of the lifting motor 76 is inserted into the gap of the end limit block 755 of the worm 75 and transmits torque; at the same time, the side of the fixing plate 71 presses the extrusion cylinder 754 on the end face of the worm 75, and the extrusion cylinder 754 pushes the cross block 752 to slide inward along the cross groove 751 to compress the recovery spring 753. The cross block 752 pushes the fixing block 743 in the sliding groove 741 outward and away from the cross groove 751, releasing the rotation lock state of the worm 75. When the lifting motor 76 is started and rotates forward, the worm gear 75 meshes with and drives all the rotating gears 711 inside the fixed plate 71 to rotate synchronously. The rotating gears 711, in conjunction with the adjusting gear 791 on the rotating rod 79 and the rack 715 on the lifting cylinder 714, drive the lifting cylinder 714 and the lifting rod 73 to slide vertically downward. The guide wire fixed at the bottom of the lifting rod 73 passes through the limiting sleeve 82 and is completely immersed in the coating liquid inside the coating cylinder 8, completing the immersion coating process for the preset time. The operator can remove and install the handle 793 at the outer end of the rotating rod 79 in advance. Rotating the handle 793 drives the rotating rod 79 to rotate, and the adjusting spring 772 pushes the locking block 773 to engage with the locking groove 792 at the locking angle, changing the meshing reference position of the adjusting gear 791 and the rack 715, and fine-tuning the maximum downward stroke of the lifting rod 73 to adapt to the processing of guide wires of different lengths and specifications.

[0052] After the guide wire is immersed in the coating for the set time, the lifting motor 76 is controlled to rotate in the opposite direction. Through the worm gear 75 and the gear rack 715, the lifting rod 73 and the guide wire are lifted upwards and completely separated from the coating liquid surface. After the lifting rod 73 reaches its maximum stroke, the conveying motor 63 continues to drive the fixing belt 64 and the limiting belt 65 to move forward. The protrusion 761 of the lifting motor 76 slides out from the gap of the limiting block 755, and the squeezing force of the fixing plate 71 on the extrusion cylinder 754 disappears. The return spring 753 inside the worm gear 75 rebounds and pushes the cross block 752 to reset outwards. The cross block 752 pushes the fixing block 743 back into the cross groove 751. With the help of the compression spring 742, the worm gear 75 is locked. The lifting rod 73 cannot be lifted or lowered unexpectedly when not in the processing position, preventing the guide wire from falling or the immersion depth from getting out of control.

[0053] After the lifting mechanism 7 leaves the dipping station along with the conveying mechanism 6, the extrusion rod 669 gradually disengages from the thick end of the convex plate 611, the extrusion force disappears, the spring 668 releases its stored energy and reverses to drive the rotating disk 667 to rotate; the arc groove 6671 pulls the sliding cylinder 666 outward along the guide groove 663, the clamping block 665 loosens the central limit post 722, and the lifting mechanism 7 is released from locking. The operator can then use the external hook to hook the sliding block 72 lifting ring 721 again to lift and remove the entire lifting mechanism 7, replace it with a brand new lifting mechanism 7 pre-installed with guide wire, and realize uninterrupted cyclic processing of the equipment, greatly improving continuous production efficiency.
