Description

Technical Field

[0001] This invention relates to the field of coating processing and production technology, specifically to a dip coating apparatus and a coating guide wire production line. Background Technology

[0002] Currently, by applying polymers and other compounds to the surface of stainless steel products, a thin and durable shape-protective coating can be formed. This coating can form a barrier to prevent the intrusion of oxygen and moisture, and enhance the material's corrosion resistance. At the same time, it can improve the surface hardness of the material and improve the performance of stainless steel. The resulting semi-finished products can be used in the subsequent manufacturing of products such as medical guidewires.

[0003] During the dip coating process, the actual heating temperature of the guide wire is greatly affected by external factors, making temperature control inconvenient. This results in different viscosities between the dip coating liquid and the guide wire during the heating and conveying process. Consequently, the coating liquid on the outer side of the guide wire cures asynchronously, leading to poor coating distribution quality on the outer wall of the guide wire. This reduces the reliability and adhesion of the guide wire coating and affects the actual performance of the guide wire. Summary of the Invention

[0093] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0094] Example 1

[0095] This embodiment provides a dip-coating apparatus; see [link / reference] Figure 1 and Figure 7 It includes a support frame 11, a solution tank module 12, a sintering module 13, and a wire guiding mechanism 14; the support frame 11 extends vertically, and the solution tank module 12, the sintering module 13, and the wire guiding mechanism 14 are installed on the support frame 11.

[0096] See Figure 2 The solution tank module 12 is equipped with an immersion coating chamber, which is suitable for immersion coating of the guide wire. The solution tank module 12 includes a base plate 126 and an immersion coating module. The solution tank module 12 is equipped with one or more immersion coating modules. The base plate 126 is fixedly connected to the support frame 11.

[0097] See Figure 2 , Figure 3 as well as Figure 5The dip coating module includes a dip coating component 121 and a connecting plate 122, which are detachably connected. The dip coating component 121 has the aforementioned dip coating cavity. An inlet and an outlet communicating with the dip coating cavity are provided on the dip coating component 121. The inlet is used for the guide wire to enter the dip coating cavity, and the outlet is used for the guide wire to exit the dip coating cavity. The outlet is located above the inlet. It should be noted that a sealing structure is provided at the inlet to prevent the dip coating liquid from leaking to the outside. The guide wire slides through this sealing structure.

[0098] See Figure 2 The solution tank module 12 also includes a stirring assembly 123, which includes a stirring drive 1231, a stirring transmission structure, and a stirring element 1235. The stirring drive 1231 is mounted on a connecting plate 122. The stirring transmission structure is rotatably mounted on the connecting plate 122 and is installed at the driving end of the stirring drive 1231. The stirring element 1235 is rotatably mounted in the dip coating chamber and is connected to the stirring transmission structure. The stirring element 1235 and the connecting plate 122 are rotatably connected. The stirring assembly 123 stirs the dip coating solution in the dip coating chamber, improving the fluidity of the dip coating solution and promoting sufficient adhesion between the dip coating solution and the guide wire. At the same time, it helps maintain the initial viscosity of the dip coating solution adhering to the guide wire, promotes the uniform viscosity of the dip coating solution on the outer wall of the guide wire in the hot drying channel 131, and improves the distribution quality of the guide wire coating.

[0099] See Figure 4 The stirring transmission structure includes a pulley assembly and an adapter 124. The pulley assembly is connected to the drive end of the stirring drive 1231, and the pulley assembly and the adapter 124 are rotatably connected. The adapter 124 is mounted on the dip-coating component 121. The pulley assembly includes a first pulley 1232, a second pulley 1233, and a connecting belt 1234. The stirring drive 1231 drives the first pulley 1232, and the connecting belt 1234 engages with and drives the first pulley 1232 and the second pulley 1233. The second pulley 1233 drives the stirring component 1235, thereby causing the stirring component 1235 to rotate and stir the dip-coating liquid in the dip-coating chamber.

[0100] See Figure 2 The agitator 1235 has a spiral groove arranged upwards around the first direction, and multiple through holes are provided on the spiral groove. The multiple through holes are evenly distributed at intervals along the spiral direction. The agitator 1235 has a connecting cavity, and the through holes and the connecting cavity are connected. The connecting cavity, the inlet and the outlet are connected. Through the spiral groove, the coating liquid is spirally transported to the upper area of ​​the coating cavity. At the same time, the gravity of the coating liquid is used to make the coating liquid enter the connecting cavity through the through holes on the spiral groove, which has the effect of collecting the coating liquid. This ensures that the guide wire is fully adhered to the coating liquid when the wire guide mechanism 14 conveys the guide wire.

[0101] The adapter 124 is provided with a connecting port, which is suitable for avoiding the guide wire from passing through. The adapter 124 is arranged to be aligned with the outlet and the connecting port. The adapter 124 is fixedly connected to the second pulley 1233.

[0102] In some embodiments, the dip coating component 121 includes a body and a cover plate, which are detachably connected, for example by a threaded connection; after the body and cover plate are installed, the body and cover plate together enclose the dip coating cavity described above; the inlet is located on the body, the outlet is located on the cover plate, and the adapter 124 is rotatably loaded on the cover plate.

[0103] See Figure 2 and Figure 3 The dip coating module also includes a connecting frame 125, which is fixedly connected to the connecting plate 122. Each dip coating module is equipped with a connecting frame 125. The entire dip coating module is transferred through the connecting frame 125 to facilitate the assembly and disassembly of the dip coating module.

[0104] See Figure 1 and Figure 6 The sintering module 13 includes a hot drying channel 131 and several heating modules 132. The hot drying channel 131 extends along a first direction, and any heating module 132 is conformally installed on the hot drying channel 131. The heating module 132 is used to control and adjust the temperature value inside the hot drying channel 131. The hot drying channel 131 and the dip coating chamber are correspondingly arranged. The hot drying channel 131 is used to establish a stable hot drying space to receive the dip-coated guide wire for sintering and curing.

[0105] See Figure 6 The heating module 132 is configured as a cylindrical structure and is sleeved and installed on the hot drying channel 131; in some embodiments, the heating module 132 is a resistance wire module.

[0106] See Figure 6 Each hot-drying channel 131 is equipped with multiple exhaust components 133, which are spaced apart on the hot-drying channel 131. One end of each exhaust component 133 is connected to the hot-drying channel 131, and the other end is adapted to be connected to an external exhaust system. By connecting the hot-drying channel 131 to the external exhaust system through the exhaust components 133, superheated gases and sintering waste gases in the hot-drying channel 131 can be discharged, facilitating temperature control and improving the forming quality of the guide wire coating.

[0107] See Figure 1The sintering module 13 also includes a control box 134, which is coupled to the heating module 132. The control box 134 is used to control the heating temperature of the heating module 132 to achieve temperature control. Each section of the hot drying channel 131 is equipped with a temperature detection element. When the detected temperature is higher than its set temperature threshold, the control box 134 controls the heating module 132 of that section to stop operating to reduce the temperature of that section. When the detected temperature is lower than its set temperature threshold, the control box 134 controls the heating module 132 of that section to operate to maintain the temperature of that section.

[0108] In this embodiment, four dip-coating modules are arranged side-by-side on the base plate 126, and the four dip-coating modules simultaneously dip-coat the four guide wires; 12 hot-drying channels 131 are configured; each dip-coating module is configured with a first body 121a, a second body 121b, and a third body 121c; the hot-drying channels 131 are configured with a first channel, a second channel, and a third channel, with the first channel correspondingly positioned above the first body 121a, the second channel correspondingly positioned above the second body 121b, and the third channel correspondingly positioned above the third body 121c; wherein, the first channel has a first to a fifth segment; along the first direction, the heating temperature of the first segment is configured to be 100℃, the heating temperature of the second segment is configured to be... The heating temperature of the first section is 150℃, the heating temperature of the third section is 200℃, the heating temperature of the fourth section is 230℃, and the heating temperature of the fifth section is 0℃; the fourth section is two meters long, and the remaining sections are one meter long; the second channel has the first to fifth sections; along the first direction, the heating temperature of the first section is 100℃, the heating temperature of the second section is 150℃, the heating temperature of the third section is 200℃, the heating temperature of the fourth section is 250℃, and the heating temperature of the fifth section is 300℃; the fifth section is two meters long, and the remaining sections are one meter long; the third channel is the same as the second channel in terms of structure and heating temperature gradient.

[0109] The dip coating apparatus provided in this embodiment transmits a guide wire through a wire mechanism 14, allowing it to pass through a first body 121a and a first channel, where a first layer of guide wire coating is applied and cured. The guide wire then passes through a second body 121b and a second channel, where a second layer of guide wire coating is applied and cured. Subsequently, the guide wire passes through a third body 121c and a third channel, where a third layer of guide wire coating is applied and cured. Finally, the wire mechanism 14 guides the guide wire out of the dip coating apparatus.

[0110] See Figure 1The wire guiding mechanism 14 has a first wire guiding state, which transmits the guide wire from the dip coating chamber to the hot drying channel 131 along a first direction. At least two dip coating chambers are arranged side-by-side. After the first wire guiding state, the wire guiding mechanism 14 also has a second wire guiding state, which conveys the guide wire along a second direction to allow the guide wire to enter another dip coating chamber. In the first wire guiding state, the wire guiding mechanism 14 guides the guide wire into the dip coating chamber to adhere the dip coating liquid, and then transmits it to the hot drying channel 131 for sintering and curing. In the second wire guiding state, the wire guiding mechanism 14 can convey the guide wire to a subsequent dip coating chamber to add new dip coating liquid to the formed coating, allowing the guide wire to undergo repeated dip coating, adapting to the actual manufacturing and processing requirements of the guide wire coating. Dip coating liquids can be configured in two or more dip coating chambers. Different dip coating chambers can be equipped with the same dip coating liquid or different dip coating liquids, depending on the specific manufacturing and processing requirements.

[0111] The dip coating apparatus provided in this embodiment contains a dip coating solution in the dip coating chamber. The heating module 132 heats the hot drying channel 131, and the wire guide mechanism 14 conveys and transmits the guide wire, causing it to adhere to the dip coating solution in the dip coating chamber and be transferred to the hot drying channel 131 for sintering of the guide wire coating. The hot drying channel 131 establishes a stable hot drying space, which facilitates temperature control and adjustment. This minimizes the influence of external temperature on the coating to be formed on the outer wall of the guide wire during sintering, thereby ensuring that the viscosity of the dip coating solution on the outer wall of the guide wire is uniform within the hot drying channel 131. This improves the coating distribution quality on the outer wall of the guide wire, promotes the curing and sintering of the dip coating solution, and enhances the reliability of the guide wire coating's adhesion, avoiding any impact on the actual performance of the guide wire.

[0112] In this embodiment, see Figure 1 , Figure 7 as well as Figure 8 The wire guiding mechanism 14 includes a drive assembly and a first wire guide wheel set 141 and a second wire guide wheel set 142 arranged at intervals. The drive assembly is adapted to drive the first wire guide wheel set 141 and the second wire guide wheel set 142 to rotate synchronously. Each wire guide wheel set is rotatably mounted on the support frame 11. The first wire guide wheel set 141 and the second wire guide wheel set 142 are used to adjust the transmission path of the guide wire along a first direction or a second direction. The drive assembly can be configured as a drive motor and a drive connecting shaft, and a set of drive assemblies can be configured for each of the first wire guide wheel set 141 and the second wire guide wheel set 142.

[0113] It should be noted that the first direction is the direction in which the wire guide mechanism 14 transmits the upward movement of the guide wire, and the second direction is the direction in which the wire guide mechanism 14 transmits the downward movement of the guide wire. The guide wire rises along the first direction into the hot baking channel 131 for heating and sintering; the guide wire descends along the second direction to cool, and the dip coating process is completed.

[0114] See Figure 1 and Figure 8The wire guiding mechanism 14 also includes a guide wheel assembly 143, an infeed wheel assembly 144, and an outfeed wheel assembly 145. At least one guide wheel assembly 143 is provided, and the guide wheel assembly 143 is located upstream of the first wire guiding wheel assembly 141. The guide wheel assembly 143 is used to pass the wire to the first wire guiding wheel assembly 141 so that the wire enters the dip coating chamber. The infeed wheel assembly 144 is used to feed the wire to the dip coating device, and the outfeed wheel assembly 145 is used to guide the wire out away from the dip coating device.

[0115] The first guide wheel assembly 141 and the second guide wheel assembly 142 are provided with two or more guide grooves; in this embodiment, each guide wheel assembly is provided with 12 guide grooves to accommodate four strands of guide wire for three dip coating processes. On the transmission path of the guide mechanism 14, the guide grooves on the first guide wheel assembly 141 and the second guide wheel assembly 142 are offset in projection onto the horizontal plane, giving the guide wire an angle deviating from the direction of gravity height, thereby satisfying the requirement to transmit the guide wire from the dip coating chamber to subsequent dip coating chambers and adjusting the transmission path of the guide wire.

[0116] In some embodiments, a ceramic layer is disposed on the surface of any guide wheel assembly. The ceramic layer has a smooth contact surface; the ceramic layer is beneficial for improving the high-temperature resistance of the guide wheel assembly and is suitable for heating and sintering conditions. Of course, any guide wheel assembly can also be made directly from ceramic materials.

[0117] Example 2

[0118] This embodiment provides a coated guide wire production line, which includes the dip coating device 1 of Embodiment 1. The coated guide wire production line is used for continuous production of guide wires; by dip coating the guide wires through the dip coating device 1, a uniformly coated guide wire coating can be formed, ensuring the production quality of the guide wires.

[0119] See Figure 9 The coating guide wire production line provided in this embodiment also includes a take-up / unwinding device 2 and a cleaning device 3. The take-up / unwinding device 2 is modularly integrated and includes an unwinding mechanism 21, a traction mechanism 22, and a take-up mechanism 23. The unwinding mechanism 21 is located upstream of the dip coating device 1, and the traction mechanism 22 is located between the dip coating device 1 and the take-up mechanism 23. The take-up / unwinding device 2 unwinds, tractions, and rewinds the guide wire, adapting to the production of guide wire coatings. The cleaning device 3 performs surface cleaning treatment on the unwound guide wire to improve the forming effect of subsequent dip coating work, resulting in high continuous production efficiency.

[0120] In this embodiment, four unwinding mechanisms 21 are configured, which can simultaneously unwind four strands of guide wire; two traction mechanisms 22 are configured, which can traction two strands of guide wire; and four winding mechanisms 23 are configured, which can simultaneously wind four strands of guide wire.

[0121] See Figure 10 and Figure 11 The unwinding mechanism 21 includes an unwinding bracket 211, an unwinding drive 212, an unwinding reel 213, a guide wheel assembly 214, and a first detection element 215. The unwinding drive 212 is mounted on the unwinding bracket 211. The unwinding reel 213 is mounted on the drive end of the unwinding drive 212. The unwinding drive 212 and the unwinding reel 213 are arranged opposite each other on both sides of the unwinding bracket 211. The guide wheel assembly 214 is rotatably mounted on the unwinding bracket 211. The first detection element 215 is adapted to detect the angular displacement of the unwinding reel 213. The unwinding reel 213, the guide wheel assembly 214, and the first detection element 215 are arranged on the same side of the unwinding bracket 211. The unwinding drive 212 drives the unwinding reel 213 to unwind the guide wire wound on it, and the traction mechanism 22 pulls the guide wire. The first detection element 215 detects the angular displacement of the unwinding reel 213 in real time and detects the tension of the conveying guide wire so that the unwinding mechanism 21 can reasonably configure the unwinding speed to adapt to the production conditions.

[0122] See Figure 11 The coated wire guide production line also includes a first sliding assembly 216, which is fixedly mounted on the unwinding bracket 211. The unwinding drive 212 and the unwinding reel 213 are jointly mounted on the sliding end of the first sliding assembly 216. The first sliding assembly 216 includes a sliding drive and a sliding frame. The unwinding drive 212 and the unwinding reel 213 are jointly mounted on the sliding frame, and the sliding drive is used to drive the sliding frame to slide horizontally. The wire guide delivered on the unwinding reel 213 is aligned with the wire guide path of the wire guide roller assembly 214 by the first sliding assembly 216, avoiding adverse interference caused by the wire guide direction. This helps improve the wire guide transmission quality, reduce wire guide delivery errors, and ensure a reliable transmission rate.

[0123] See Figure 15 and Figure 16 The traction mechanism 22 includes a traction bracket 221, a traction drive component 222, a traction drive wheel 223, and a traction driven wheel 224. The mounting end of the traction drive component 222 is fixedly disposed with the traction bracket 221. The traction drive wheel 223 is mounted on the drive end of the traction drive component 222. The traction drive wheel 223 and the traction driven wheel 224 are rotatably configured with the traction bracket 221. The traction drive component 222 drives the traction drive wheel 223 and drives the traction driven wheel 224 to rotate, so that the traction drive wheel 223 and the traction driven wheel 224 pull the guide wire wound on it. The traction mechanism 22 is equipped with four traction auxiliary wheels 225, and a guide wire transmission space is formed between each pair of traction auxiliary wheels 225 to align with the winding direction of the winding mechanism 23.

[0124] See Figure 17 and Figure 18The winding mechanism 23 includes a winding bracket 231, a winding drive 232, a winding reel 233, a guide wheel assembly 234, and a second detection element 235. The winding drive 232 is mounted on the winding bracket 231. The winding reel 233 is mounted on the drive end of the winding drive 232. The winding drive 232 and the winding reel 233 are arranged opposite each other on both sides of the winding bracket 231. The guide wheel assembly 234 is rotatably mounted on the winding bracket 231. The second detection element 235 is used to detect the coating thickness of the guide wire. The detection area of ​​the second detection element 235 is set on the guide path of the guide wire by the guide wheel assembly 234. The winding reel 233, the guide wheel assembly 234, and the second detection element 235 are arranged on the same side of the winding bracket 231. The winding drive 232 drives the winding reel 233 to wind the guide wire, the directional wheel group 234 guides and limits the conveying path of the guide wire, and the second detection element 235 detects the coating thickness of the guide wire in real time to provide a reference for subsequent classification of the guide wire.

[0125] See Figure 18 The coated guide wire production line also includes a second sliding assembly 237, which is fixedly mounted on the winding bracket 231. The winding drive 232 and the winding reel 233 are jointly mounted on the sliding end of the second sliding assembly 237. The second sliding assembly 237 drives the winding reel 233 to slide, so that the guide wire being wound gradually winds onto the winding reel 233, promoting the winding process.

[0126] See Figure 9 The cleaning device 3 includes a plasma cleaner 31 and an ultrasonic cleaner 32. The plasma cleaner 31 is located downstream of the unwinding mechanism 21; the ultrasonic cleaner 32 is located between the plasma cleaner 31 and the dip coating device 1. The plasma cleaner 31 is used to clean oil and other impurities from the surface of the guide wire, while the ultrasonic cleaner 32 is used to further clean dust and other impurities from the surface of the guide wire, improving the cleanliness of the guide wire surface. This facilitates the adhesion and sintering of the dip coating solution to the outer wall of the guide wire during subsequent dip coating operations, and improves the forming effect of the guide wire coating. The plasma cleaner 31 and the ultrasonic cleaner 32 are connected in series, enabling them to jointly perform surface cleaning treatment on multiple strands of guide wire.

[0127] See Figure 12 and Figure 13The plasma cleaner 31 includes a wire guide module 311, a plasma processing module 312, several plasma spray guns 313, and a filter element 314. The wire guide module 311 is adapted to convey the guide wire to the cleaning chamber; the plasma processing module 312 is adapted to generate plasma; the input end of each plasma spray gun 313 is connected to the plasma processing module 312, and the output end faces the conveying path on which the wire guide module 311 is located; the filter element 314 is used to filter the cleaning chamber. Plasma gas generated by the plasma processing module 312 is sprayed onto the guide wire on the conveying path of the wire guide module 311 by the plasma spray guns 313 for cleaning. The plasma spray guns 313 are symmetrically arranged on both sides of the conveying path of the wire guide module 311. The filter element 314 can be configured as an air filter to filter and collect oil and other impurities on the surface of the guide wire.

[0128] See Figure 14 The ultrasonic cleaner 32 includes a carrier 321, a rotating wheel module 322, a first thread wheel module 323, and a second thread wheel module 324. The carrier 321 has a receiving cavity suitable for holding cleaning fluid. The rotating wheel module 322 is disposed within the receiving cavity. The first thread wheel module 323 and the second thread wheel module 324 are arranged opposite to each other and rotatably mounted on the carrier 321. The first thread wheel module 323 and the rotating wheel module 322 work together to deliver the guide wire into the receiving cavity, allowing the guide wire to contact the cleaning fluid within the cavity. The ultrasonic cleaner 32 is equipped with an ultrasonic transducer (not shown in the figure), which generates ultrasonic waves to act on the cleaning fluid and clean the dirt on the guide wire. The second thread wheel module 324 guides the guide wire out, and after drying or air drying, it is then introduced into the dip coating device 1 for dip coating. The ultrasonic cleaner 32 can clean multiple guide wires simultaneously. It should be noted that the cleaning fluid in the containment cavity can be updated and configured via external devices, and the cleaning fluid after cleaning can be discharged.

[0129] The coating guide wire production line provided by this invention operates as follows:

[0130] The guide wire is fed and unwound via the unwinding mechanism 21. The fed guide wire is cleaned sequentially by the plasma cleaner 31 and the ultrasonic cleaner 32. The guide wire enters the dip coating device 1, and the wire guide mechanism 14 guides the guide wire into the dip coating chamber to coat it with the dip coating liquid. Then, the guide wire rises into the hot drying channel 131 for sintering and curing. After the wire guide mechanism 14 exits the hot drying channel 131, it is passed downwards for cooling. When it is necessary to repeat the dip coating with a new dip coating liquid, the wire guide mechanism 14 guides the guide wire into the dip coating chamber of the dip coating module to coat it with the new dip coating liquid. Then, it is heated, sintered, cured, and cooled. The traction mechanism 22 provides traction force to pull the guide wire downstream of the dip coating device 1, and the winding mechanism 23 performs the material collection and winding of the guide wire.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
