Description

Technical Field

[0001] This invention relates to a magnetic product straightening auxiliary tool, a coating equipment and its working method, belonging to the field of medical device technology. Background Technology

[0002] In the field of medical coating applications, the need to maintain the efficiency, cleanliness, sterility, stability, and uniformity of product surface coating curing has spurred the emergence of a large number of coating equipment. In today's market, more and more products require special surface treatments to meet their application scenarios, leading to a growing demand for such equipment. The greatest demand is in medical consumables, especially various active and passive interventional medical instruments and devices used in human medicine. These devices come into contact with the human body and must achieve the functionality required for medical scenarios (such as lubrication, antibacterial properties, and anticoagulation) while ensuring absolute safety, minimizing or eliminating harm to the human body. Therefore, the requirements for coatings and coating processes are extremely high, demanding much stricter requirements for the stability of the coating solution and the comprehensiveness and uniformity of the coating.

[0003] Especially for coating slender magnet products, because the products themselves are relatively thin and lightweight, when the coating length is long, the wire is prone to uncontrolled left and right movement, which can easily cause it to rub against other parts of the equipment or become entangled with other magnet products, resulting in an unsatisfactory coating effect. It is essential to ensure the comprehensiveness and uniformity of the magnet product coating. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetic product straightening auxiliary tooling, a coating equipment, and a method for operating the same, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a magnetic product straightening auxiliary fixture, wherein the magnetic product straightening auxiliary fixture is detachably arranged directly below the magnetic product and does not contact the magnetic product, and the magnetic product straightening auxiliary fixture includes: A support base on which a fixed plane is formed; Several magnet blocks are arranged at intervals within the accommodating space, and at least one of the magnet products may be distributed in the space above the magnet blocks.

[0006] Furthermore, the magnet blocks are divided into two groups and arranged alternately, with the ends of the two groups of magnet blocks not collinear.

[0007] Furthermore, a protective shell is arranged on the support base and placed above the magnet block, and the protective shell is detachably connected to the fixed plane.

[0008] Furthermore, the protective shell is made of a polymer material.

[0009] Furthermore, the upper surface of the protective shell is no more than 5 mm away from the end of the magnet product.

[0010] This application also provides a coating equipment, which includes the magnet product straightening auxiliary fixture as described above. The coating equipment also includes a magnet product sample hanging module, a coating module, and a curing module. The magnet product straightening auxiliary fixture is detachably installed on the coating module and / or the movement path of the magnet product.

[0011] Furthermore, a fixing seat is formed extending from both sides of the support seat in a direction away from the support seat, and a fixing structure is formed at the end of the fixing seat.

[0012] Furthermore, the coating equipment includes a coating chamber, the curing module is arranged on the side wall of the coating chamber, the magnet product is fixed to the top of the coating chamber by a magnet product hanging module, the coating module is arranged at the bottom of the coating chamber and has a coating liquid containing unit, and a quick-locking structure that cooperates with the fixing structure to lock or unlock the support seat is arranged on the side wall of the coating chamber and directly above the coating module.

[0013] This application also provides a working method applicable to the above-mentioned coating equipment, the working method comprising: The magnetic product is fixed directly above the coating module using the magnetic product hanging module; Drive the coating module and / or the magnetic product sample hanging module to move so that the magnetic product is immersed in or leaves the coating liquid in the coating liquid containing unit to perform the coating operation on the magnetic product; After the coating process is completed, the magnet product straightening auxiliary fixture is fixed directly below the magnet product so that each magnet product is vertically suspended above the magnet product straightening auxiliary fixture. The curing module is activated to cure the coated magnet product.

[0014] Furthermore, the working method also includes: before the coating operation, fixing the magnet product straightening auxiliary fixture directly below the magnet product, and removing the magnet product straightening auxiliary fixture after all magnet products are vertically suspended.

[0015] The beneficial effects of this invention are as follows: This application generates a controllable magnetic field force by arranging magnet blocks at intervals, forming a non-contact flexible constraint on the slender magnet product, effectively suppressing the lateral swing and rotation of the magnet product, and preventing it from getting entangled with equipment parts or other magnet products; the magnetic force acts through the length direction of the magnet product, ensuring that the entire magnet product remains in a stable suspended state during coating, which not only avoids coating damage caused by physical contact, but also significantly improves the comprehensiveness and uniformity of coating.

[0016] In addition, the magnet is enclosed between the protective shell and the support base by the protective shell, which not only protects the magnet from coating liquid contamination, but also prevents the magnetic field from interfering with the surrounding equipment. Its detachable design can be flexibly adjusted according to the coating process of the magnet product.

[0017] This application also provides a coating application device that effectively solves the core stability problem of slender magnetic products during the coating and curing process by integrating a detachable magnetic product alignment auxiliary fixture into the coating module and / or the magnetic product movement path. The controllable magnetic field generated by the magnetic block forms a non-contact levitation and alignment of the magnetic product, significantly suppressing its lateral swaying and rotation, preventing the magnetic product from getting entangled with equipment components or adjacent magnetic products, ensuring that the magnetic product is always on a predetermined trajectory during coating, and greatly improving the comprehensiveness and uniformity of coating coverage.

[0018] This application also provides a working method that systematically solves the stability problem of slender magnetic products during the coating and curing stages through a step-by-step collaborative mechanism of first moving the coating and then using magnetic alignment. During the coating operation, relative movement between the magnetic product hanging module and the coating module is allowed to ensure efficient coverage of the coating liquid; and before the transition to curing, a magnetic product alignment auxiliary tooling is precisely introduced, using magnetic blocks to perform non-contact vertical suspension of the magnetic product, which not only avoids coating dripping or displacement caused by gravity during the curing process, but also completely eliminates the risk of magnetic product swinging and entanglement, significantly improving the safety and consistency of medical consumable coating.

[0019] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] Please refer to Figure 1 This application discloses an embodiment of a magnet product straightening auxiliary fixture 100. The fixture 100 is detachably arranged directly below the magnet product. The fixture 100 includes a support base 10 and a plurality of magnet blocks 20 disposed within the support base 10. In this embodiment, the magnet product is made of a magnetic material, i.e., a product that can be attracted by the magnet blocks 20. The material may contain iron, cobalt, nickel, or their alloys. The magnet blocks 20 use their magnetic force to perform a non-contact straightening operation on the magnet product, avoiding direct contact with the magnet product and improving the comprehensiveness and uniformity of the magnet product coating. Of course, in other embodiments, there are also non-magnetic products. In such cases, magnetic accessories can be arranged at the movable end of the product to cooperate with the magnet product straightening auxiliary fixture 100 for straightening non-magnetic products.

[0025] A fixed plane 11 is formed on the support base 10. Several magnet blocks 20 are arranged at intervals on the fixed plane 11. At least one magnet product can be distributed in the space above the magnet blocks 20. The number of magnet products arranged above the magnet blocks 20 is flexibly arranged according to the length of the magnet blocks 20 and the magnetic attraction effect of the magnet blocks 20 on the magnet products. No specific limitation is made here. The magnet blocks 20 are arranged at intervals so that the magnet products can be attracted by the desired magnet blocks 20 under the magnetic force of the magnet blocks 20, while avoiding being attracted by adjacent magnet blocks 20, which would cause the axis of the magnet products to deviate.

[0026] In one embodiment, a plurality of magnet blocks 20 are divided into two groups and arranged alternately, with the ends of the two groups of magnet blocks 20 not collinear. This allows the magnet products to be arranged in an alternating manner, increasing the spacing between the magnet products to a certain extent and preventing adjacent magnet products from being unable to be attracted by the desired magnet block. Admittedly, in other embodiments, the magnet blocks 20 can be divided into more groups and arranged alternately, which can be set as needed and is not specifically limited here.

[0027] In one embodiment, a protective shell 12 is arranged on the support base 10, covering the magnet block 20. The protective shell 12 is detachably connected to the fixing plane 11. The magnet block 20 is fixed on the fixing plane 11 through the detachable protective shell 12 and the fixing plane 11. The upper surface of the protective shell 12 is spaced apart from the bottom end of the magnet product. In this way, it avoids contact between the magnet product straightening auxiliary tooling 100 and the magnet product, and at the same time, it also protects the magnet block 20. In addition, it is convenient to replace and adjust the magnet block 20. The protective shell 12 and the fixing plane 11 can also be made of different materials according to their functions to reduce production costs. Of course, in other embodiments, the support base 10 and the protective shell 12 can also be integrally formed. By opening holes on their sides, the magnet block 20 fixed on the support plate can be inserted into the interior of the integrally formed support base 10 and protective shell 12 through the openings.

[0028] In one embodiment, the protective shell 12 is made of a polymer material. The specific selection of the polymer material can be a material that is corrosion-resistant, easy to clean, lightweight, and has little weakening effect on the magnetism of the magnet, such as POM, PTFE, or PEEK. It does not actually come into contact with the magnet product, will not damage the coating on the magnet product, and will not cause pollution to the magnet product. At the same time, it can also prevent the magnetic field from interfering with the surrounding equipment.

[0029] In one embodiment, the upper surface of the support base 10 is no more than 5 mm away from the end of the magnet product. In this way, the magnetic attraction force at the end of the magnet product is maximized without the magnet product contacting the support base 10, thereby ensuring the uprighting effect of the magnet product.

[0030] Please refer to Figure 2This application also provides a coating equipment 30, which includes a magnet product sample hanging module, a coating module 33, a curing module 32, and a magnet product straightening auxiliary fixture 100 as described above. The magnet product straightening auxiliary fixture 100 is detachably installed on the coating module 33 and / or the movement path of the magnet product. The coating equipment 30 also includes a drive module, which is used to drive the coating module 33 to move toward the magnet product for coating, or drive the magnet product to move toward the coating module 33 for coating, or drive the coating module 33 and the magnet product to move toward each other for coating. These are all prior art and can be set as needed, and are not specifically limited here.

[0031] In one embodiment, a fixing seat 13 is formed extending from both sides of the support seat 10 toward a direction away from the support seat 10, and a fixing structure is formed at the end of the fixing seat 13. The fixing structure is used in conjunction with the fixing member for fixed connection, which facilitates disassembly and installation.

[0032] In one embodiment, the coating equipment 30 includes a coating box 31, a curing module 32 arranged on the side wall of the coating box 31, a magnet product fixed to the top of the coating box 31 by a magnet product hanging module, and a coating module 33 arranged at the bottom of the coating box 31 and having a coating liquid receiving unit. A quick-locking structure 34, which cooperates with the fixing structure to lock or unlock the support seat 10, is arranged on the side wall of the coating box 31 and directly above the coating module 33. The support seat 10 is locked or unlocked by inserting the fixing slot into the quick-locking structure 34 and rotating the quick-locking structure 34. In this embodiment, the fixing structure is a fixing slot, and the quick-locking structure 34 is a quick-locking handle; both are existing technologies and will not be described in detail here. Of course, in other embodiments, the magnet product straightening auxiliary tooling 100 can also be installed and disassembled using other detachable methods, such as fixing buckles, fixing clamps, fixing bolts, etc., which can be set as needed and are not specifically limited here.

[0033] This application also provides a working method applicable to the above-mentioned coating equipment 30, the working method including: The magnetic product is fixed directly above the coating module 33 using the magnetic product hanging module; Drive the coating module 33 and / or the magnet product sample hanging module to move so that the magnet product is immersed in or leaves the coating liquid in the coating liquid containing unit to perform the coating operation on the magnet product; After the coating process is completed, the magnet product straightening auxiliary fixture 100 is fixed directly below the magnet product so that each magnet product is vertically suspended directly above the magnet product straightening auxiliary fixture 100. The curing module 32 is activated to cure the coated magnet product.

[0034] In one embodiment, the working method further includes: before the coating operation, fixing the magnet product straightening auxiliary fixture 100 directly below the magnet product, and removing the magnet product straightening auxiliary fixture 100 after all the magnet products are vertically suspended.

[0035] This application generates a controllable magnetic field force by spaced-out magnet blocks, forming a non-contact flexible constraint on slender magnet products. This effectively suppresses the lateral swaying and rotation of the magnet products, preventing them from entangled with equipment components or other magnet products. The magnetic force extends throughout the length of the magnet products, ensuring that the entire magnet product remains in a stable suspended state during coating. This avoids coating damage caused by physical contact and significantly improves the comprehensiveness and uniformity of the coating.

[0036] In addition, the magnet is enclosed between the protective shell and the support base by the protective shell, which not only protects the magnet from coating liquid contamination, but also prevents the magnetic field from interfering with the surrounding equipment. Its detachable design can be flexibly adjusted according to the coating process of the magnet product.

[0037] This application also provides a coating application device that effectively solves the core stability problem of slender magnetic products during the coating and curing process by integrating a detachable magnetic product alignment auxiliary fixture into the coating module and / or the magnetic product movement path. The controllable magnetic field generated by the magnetic block forms a non-contact levitation and alignment of the magnetic product, significantly suppressing its lateral swaying and rotation, preventing the magnetic product from getting entangled with equipment components or adjacent magnetic products, ensuring that the magnetic product is always on a predetermined trajectory during coating, and greatly improving the comprehensiveness and uniformity of coating coverage.

[0038] This application also provides a working method that systematically solves the stability problem of slender magnetic products during the coating and curing stages through a step-by-step collaborative mechanism of first moving the coating and then using magnetic alignment. During the coating operation, relative movement between the magnetic product hanging module and the coating module is allowed to ensure efficient coverage of the coating liquid; and before the transition to curing, a magnetic product alignment auxiliary tooling is precisely introduced, using magnetic blocks to perform non-contact vertical suspension of the magnetic product, which not only avoids coating dripping or displacement caused by gravity during the curing process, but also completely eliminates the risk of magnetic product swinging and entanglement, significantly improving the safety and consistency of medical consumable coating.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
