Description

Technical Field

[0001] This utility model relates to the field of coating dip-coating and curing technology, and more specifically, to a pre-curing device and a coating curing equipment. Background Technology

[0002] With the rapid development of medical technology, more and more vascular interventional medical devices are being used in clinical treatment. Various types of catheters are being implanted into human blood vessels. To improve the compatibility of catheters with blood and reduce the resistance of catheters passing through blood vessels, it is necessary to modify the surface of these catheters to reduce patient discomfort. In existing technologies, the coating process mostly involves filling a coating solution tube with the coating solution, then immersing the workpiece in the coating solution with a catheter clamp, and then slowly pulling it out. After the entire tube is pulled out, a curing chamber is opened to cure the coating on the entire surface of the tube.

[0003] However, during the tube removal process and before the curing chamber is opened, the coating solution on the tube surface will slowly flow downwards due to gravity, eventually accumulating at the end of the tube. After curing, teardrop-shaped protrusions will form on the end surface of the tube, affecting product quality. Utility Model Content

[0009] In an optional embodiment, the inner wall of the housing is coated with a light-absorbing material layer.

[0010] In an alternative implementation, the base is configured to be height-adjustable.

[0011] In an optional embodiment, the base includes two telescopic columns, which are spaced apart.

[0012] An embodiment of this utility model also provides a coating curing device, including a fixing frame, a coating solution tube, and a pre-curing device as described in any of the above embodiments. The coating solution tube is disposed on the fixing frame, the base is connected to the fixing frame, and the pre-curing device is located above the coating solution tube. The first through hole and the second through hole are aligned with the opening of the coating solution tube.

[0013] In an optional embodiment, the fixing frame is provided with a guide tube clamp for clamping the workpiece tube body.

[0014] In an optional embodiment, the catheter clamp is slidably connected to the retainer.

[0015] The beneficial effects of the pre-curing device and coating curing equipment of this utility model embodiment include, for example: The pre-curing device includes a base, a housing, and a light strip, with the housing connected to the base.

The light strip is located within the pre-curing chamber and includes a lamp bead housing, a lamp bead, and optical fiber material. The lamp bead housing is connected to the housing, with the lamp bead housed within it and filled with optical fiber material. The tube to be processed passes through the first and second through-holes into the coating solution, and upon removal, passes through the pre-curing chamber for pre-curing. By using the pre-curing device, the light emitted by the lamp bead irradiates the tube, adding a pre-curing step before the tube enters the curing chamber. This reduces the fluidity of the coating solution on the tube surface, avoids teardrop effects at the ends, and improves the uniformity of the coating thickness. By filling the lamp bead housing with optical fiber material, the light emitted by the lamp bead is more concentrated and does not scatter over a large area, thus preventing the light from affecting the coating solution in the external coating solution tube.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] With the rapid development of medical technology, more and more vascular interventional medical devices are being used in clinical treatment. Various types of catheters are being implanted into human blood vessels. To improve the compatibility of catheters with blood and reduce the resistance of catheters passing through blood vessels, it is necessary to modify the surface of these catheters to reduce patient discomfort. In existing technologies, the coating process mostly involves filling a coating solution tube, then immersing the workpiece in the coating solution using a catheter clamp, and then slowly pulling it out. After the entire tube is pulled out, a curing chamber is opened to cure the coating on the entire surface of the tube. However, during the tube removal process and before the curing chamber is opened, the coating solution on the tube surface slowly flows downwards due to gravity, eventually accumulating at the end of the tube. After curing, teardrop-shaped protrusions form on the surface of the tube end, affecting product quality.

[0026] Based on this, please refer to Figures 1-3 The pre-curing device 100 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This pre-curing device 100 and the coating curing equipment 1000 can pre-cur the coating on the pipe fitting 2000 to reduce the fluidity of the coating, avoid teardrop effects at the ends, thereby improving the uniformity of the coating thickness and ensuring product quality. This pre-curing device 100 is applied to the coating curing equipment 1000, and all equipment with the pre-curing device 100 has the same functions as described above.

[0027] Figure 1 This is a schematic diagram of the coating curing device 1000 provided in an embodiment of this utility model. Please refer to [link / reference]. Figure 1 In this embodiment, the coating curing equipment 1000 includes a fixing frame 200, a coating solution tube 300, and a pre-curing device 100. The coating solution tube 300 is mounted on the fixing frame 200, and the base 110 is connected to the fixing frame 200. The pre-curing device 100 is located above the coating solution tube 300. The first through hole 122 and the second through hole 123 are aligned with the opening of the coating solution tube 300. The coating solution tube 300 is filled with coating solution. The tube to be processed 2000 passes through the first through hole 122 and the second through hole 123 and is immersed in the coating solution tube 300 to form a coating on the surface of the tube 2000. Then, the tube 2000 is slowly pulled out. During the pulling process, the tube 2000 passes through the pre-curing chamber 121 of the pre-curing device 100, where its surface is pre-cured, reducing the fluidity of the coating solution and avoiding the teardrop effect at the end, thereby improving the uniformity of the coating thickness and ensuring product quality.

[0028] The pre-curing device 100 is directly fixed to the mounting bracket 200 and precisely positioned above the coating solution tube 300, with the through-hole aligned with the tube opening. This forms a continuous vertical working path of "immersion-lifting-pre-curing." After the conduit is lifted out of the coating solution, it can immediately enter the pre-curing zone in the shortest possible time and path. This minimizes the time it takes for the coating liquid to begin flowing and accumulating under gravity, fixing the "teardrops" at the very moment they begin to form, achieving optimal preventative effect.

[0029] Optionally, in this embodiment, the fixing frame 200 is provided with a guide tube clamp 210, which is used to clamp the workpiece tube body. By providing the guide tube clamp 210, the position of the tube 2000 can be fixed.

[0030] In addition, please continue to refer to Figure 1To improve coating quality, the conduit clamp 210 in this embodiment is slidably connected to the fixing frame 200. The conduit clamp 210 holds the tube 2000 and slides relative to the fixing frame 200 to allow the tube 2000 to be immersed in the coating solution tube 300 or pulled out of the coating solution tube 300 and pass through the pre-curing device 100. In this embodiment, the fixing frame 200 is provided with a guide rail 220, and the conduit clamp 210 is sleeved on the guide rail 220 and can slide up and down along the guide rail 220. The tube 2000 is clamped and fixed to the conduit clamp 210. The conduit clamp 210 moves up and down along the guide rail 220, which can drive the tube 2000 to be immersed in the coating solution tube 300, or drive the tube 2000 to be coated and then pulled upward. To achieve precise stroke control, a linear motor or other driving component can also be provided. The driving component is connected to the conduit clamp 210 and drives the conduit clamp 210 to move relative to the fixing frame 200. The drive unit can control the moving speed, acceleration, and stroke position of the tubing clamp 210. Of course, the sliding connection structure can also be designed in other structural forms, such as a groove on the fixing frame 200, with the tubing clamp 210 slidingly engaging with the groove via a slider, etc., which is not limited here. The tubing 2000 can also be manually clamped, causing it to be immersed and pulled out, which is also not limited here.

[0031] In this embodiment, the mounting bracket 200 is also provided with a solution tube clamp 230, which clamps and fixes the coating solution tube 300. Optionally, the base 110 of the pre-curing device 100 is connected to the solution tube clamp 230. Of course, the base 110 can also be connected to other structures of the mounting bracket 200, which is not limited here.

[0032] The pre-curing device 100 is described in detail below.

[0033] Figure 2 This is a schematic diagram from a first perspective of the pre-curing device 100 provided in an embodiment of the present invention; Figure 3 This is a schematic diagram from a second perspective of the pre-curing device 100 provided in an embodiment of the present invention; Figure 6 This is a schematic diagram of the light strip 130 provided in an embodiment of this utility model. Please refer to [link / reference]. Figure 2 and Figure 3 and combined Figure 6This utility model provides a pre-curing device 100, including a base 110, a housing 120, and a light strip 130. The housing 120 is connected to the base 110. The housing 120 has a pre-curing chamber 121, and the housing 120 has a first through hole 122 and a second through hole 123 arranged opposite to each other, both of which communicate with the pre-curing chamber 121. The light strip 130 is located inside the pre-curing chamber 121. The light strip 130 includes a lamp bead housing 131, a lamp bead 132, and optical fiber material. The lamp bead housing 131 is connected to the housing 120, and the lamp bead 132 is disposed inside the lamp bead housing 131, which is filled with optical fiber material. The tube to be processed 2000 passes through the first through hole 122 and the second through hole 123 to enter the coating solution, and then, when it is taken out, it passes through the pre-curing chamber 121 for pre-curing. By setting up a pre-curing device 100, the light emitted by the LED bead 132 irradiates the tube 2000, adding a pre-curing step to the tube 2000 before it enters the curing chamber. This reduces the fluidity of the coating solution on the surface of the tube 2000, avoids the teardrop effect at the end, and improves the uniformity of the coating thickness. By filling the LED bead housing 131 with optical fiber material, the light emitted by the LED bead 132 can be more concentrated and will not be scattered over a large area, thus preventing the light from affecting the coating solution in the external coating solution tube 300.

[0034] Optionally, the cable of the LED bead 132 is connected to the main control board of the coating curing equipment 1000, and the power of the light emitted by the LED bead 132 is adjusted by the main control board to meet the pre-curing requirements of different coatings.

[0035] To improve the adaptability and versatility of the equipment, the base 110 in this embodiment is configured to be height-adjustable. The linear light source of the pre-curing device 100 needs to precisely illuminate the most critical area where the conduit has just been pulled out of the coating solution tube 300 and the coating liquid is about to begin to accumulate downwards. By adjusting the height of the base 110, the position of the pre-curing device 100 relative to the conduit and the coating solution tube 300 can be finely adjusted to ensure that the linear light source accurately hits the target position and achieves the best pre-curing effect. If a coating solution tube 300 of a different height or model is replaced, the pre-curing device 100 can be realigned by adjusting the base 110, enhancing the adaptability and versatility of the equipment.

[0036] Specifically, in this embodiment, the base 110 includes two telescopic columns 111, which are spaced apart. By designing the base 110 as telescopic columns 111, the structure of the pre-curing device 100 can be simplified. Furthermore, by providing two telescopic columns 111, the base 110 can be raised and lowered smoothly during adjustment, effectively preventing possible lateral swaying or rotation during the raising and lowering process, thus ensuring the stability and accuracy of the raising and lowering. This also improves safety and reliability. Of course, the base 110 can also be adjusted in height by providing multiple layers of pads, or other telescopic drive mechanisms can be used; this is not limited here.

[0037] Figure 4 This is a schematic diagram from a second perspective of the pre-curing device 100 provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the AA cross-section provided in an embodiment of this utility model. To ensure coating uniformity, please refer to... Figure 4 and Figure 5 In this embodiment, there are multiple light strips 130, and the multiple light strips 130 are symmetrically arranged about the center line 124 of the pre-curing chamber 121.

[0038] To enhance the pre-curing effect, the light strip 130 in this embodiment is positioned near the second through hole 123, that is, the light strip 130 is positioned in the pre-curing chamber 121 near the coating solution tube 300. When the conduit is first pulled out of the coating solution, the coating liquid film on its surface is the least stable and will immediately begin to flow downwards and accumulate under the influence of gravity. This "flow initiation point" occurs the instant the conduit leaves the liquid surface. Positioning the pre-curing light source as close as possible to this "initiation point" means that the coating liquid can be cured and locked in place as soon as it begins to flow and before it has a large amount of liquid accumulated at the end. This can rapidly increase the surface viscosity of the coating liquid, thereby greatly enhancing its anti-flow ability.

[0039] Please see Figure 5 In this embodiment, the light strip 130 is angled to the center line of symmetry 124. This design allows for more concentrated guidance of light energy to the surface of the tube 2000, enhancing light intensity. The tilted illumination also increases the effective illumination area, thereby improving the efficiency of light energy utilization.

[0040] Optionally, in this embodiment, the light strip 130 is set at a 45° angle to the center line of symmetry 124. Of course, the light strip 130 can also be set at other angles to the center line of symmetry 124, such as 90°, 30°, etc., which are not limited here. By adjusting the angle at which the light strip 130 emits light, it can be ensured that the light can cover the surface of both thinner and thicker conduits in a better manner, thus enhancing the versatility of the device.

[0041] To prevent the light emitted by the light strip 130 from being scattered inside the pre-curing chamber 121 and affecting the pre-curing effect, the inner wall of the outer shell 120 in this embodiment is coated with a light-absorbing material layer 140.

[0042] In summary, the pre-curing device 100 includes a base 110, a housing 120, and a light strip 130. The housing 120 is connected to the base 110. The housing 120 has a pre-curing chamber 121, and the housing 120 has a first through hole 122 and a second through hole 123 arranged opposite to each other, both of which communicate with the pre-curing chamber 121. The light strip 130 is located inside the pre-curing chamber 121. The light strip 130 includes a lamp bead housing 131, a lamp bead 132, and optical fiber material. The lamp bead housing 131 is connected to the housing 120, and the lamp bead 132 is disposed inside the lamp bead housing 131, which is filled with optical fiber material. The tube to be processed 2000 passes through the first through hole 122 and the second through hole 123 into the coating solution, and then, when it is removed, it passes through the pre-curing chamber 121 for pre-curing. By setting up a pre-curing device 100, the light emitted by the LED bead 132 irradiates the tube 2000, adding a pre-curing step to the tube 2000 before it enters the curing chamber. This reduces the fluidity of the coating solution on the surface of the tube 2000, avoids the teardrop effect at the end, and improves the uniformity of the coating thickness. By filling the LED bead housing 131 with optical fiber material, the light emitted by the LED bead 132 can be more concentrated and will not be scattered over a large area, thus preventing the light from affecting the coating solution in the external coating solution tube 300.

[0043] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
