Description

TECHNICAL FIELD

[0001] The present application relates to the field of laryngoscope blade coating processing, in particular to a laryngoscope blade coating processing device and method. BACKGROUND

[0002] Laryngoscope blades are often used for tracheal intubation during bedside surgery anesthesia or rescue of critically ill patients. Laryngoscope blades are used in combination with laryngoscopes. The conventional laryngoscope blade structure includes a tongue depressor for pressing against the tongue root when entering the oral cavity. The laryngoscope blade is provided with a mounting cavity matching the laryngoscope. The mounting cavity has a viewing window at the front end. The lens of the laryngoscope can observe the laryngeal condition of the patient through the viewing window at the front end of the mounting cavity. In order to achieve high-definition imaging of the laryngoscope, the exterior of the viewing window at the front end of the laryngoscope blade needs to be coated with an anti-fog coating.

[0003] Currently, laryngoscope blade coating is mostly applied manually. After coating is completed, the coated laryngoscope blades are left to dry naturally or are placed in an oven for curing. However, if the laryngoscope blades are not placed properly, the surface of the uncured coating will be uneven, resulting in defective products and affecting the imaging quality of the laryngoscope. In addition, before coating, disposable laryngoscope blades need to be cleaned and dried. Currently, cleaning and drying are mostly performed by directly placing a plurality of laryngoscope blades in an ultrasonic cleaning tank for ultrasonic cleaning. During the cleaning process, the high-frequency vibration of the ultrasonic cleaning machine will cause the laryngoscope blades to rub against each other, resulting in collisions and scratches that affect the appearance of the products. Moreover, if the laryngoscope blades are cleaned again after coating, the coating on the end face of the laryngoscope blades may be damaged during the cleaning process. Currently, there is no standard processing device for each production process in the production process of laryngoscope blades, resulting in a high defective rate. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a laryngoscope blade coating processing device that can improve the yield of processing and production.

[0005] The present application also provides a laryngoscope blade coating processing method using the above-mentioned laryngoscope blade coating processing device.

[0006] According to a first aspect of the present invention, a laryngeal slide coating processing apparatus is used for processing a coating on a laryngeal slide window. The laryngeal slide has an installation cavity, and the window is located at the front end of the installation cavity. The exterior of the window is used to coat the surface with the coating. The apparatus includes: a processing table; a fixing mechanism including a support column, a first clamp, and a second clamp, wherein the support column and the processing table are rotatably connected, the support column extends into the installation cavity and abuts against the inner wall of the installation cavity, the first clamp is disposed on the processing table and is located on one side of the support column, abutting against one side of the laryngeal slide, the second clamp is disposed on the processing table and is located on the other side of the support column, abutting against the other side of the laryngeal slide; and a cleaning mechanism including a cleaning table with a cleaning tank, the processing table being located above the cleaning tank, the processing table and the cleaning table being rotatably connected, and the cleaning tank containing cleaning fluid.

[0007] The laryngeal slide coating processing apparatus according to embodiments of the present invention has at least the following technical effects: By rotatably connecting the processing table to the support column, the support column can be rotated to adjust the angle and position of the laryngeal slide supported by the support column, thereby adjusting the position of the laryngeal slide window and ensuring that the window has a predetermined angle with the horizontal plane. Generally, it is necessary to ensure that the window is parallel to the horizontal plane, so that the subsequent coating steps can proceed smoothly and the coating quality can be guaranteed, preventing problems such as incomplete application, unevenness, and paint accumulation on one side of the window under gravity. Furthermore, by rotatably connecting the processing table above the cleaning tank, the processing table can be flipped before and after the coating step, facilitating the cleaning of the laryngeal slide, especially the window position, ensuring the window is clean before and after the coating step. Moreover, since the laryngeal slide is sleeved on the support column and fixed by the first and second clamps, the position of the laryngeal slide is fixed, and a certain gap can be maintained between multiple laryngeal slides, so they will not collide during cleaning, thus preventing damage, scratches, or coating destruction.

[0008] According to some embodiments of the present invention, a synchronous rotation mechanism is further included, which includes a column-rotating shaft, an adjusting knob, and a column positioning assembly. Multiple fixing mechanisms are provided. The column-rotating shaft is rotatably connected to the processing table. All support columns of the fixing mechanisms are connected to the column-rotating shaft. The adjusting knob is connected to one end of the column-rotating shaft. The support columns and the column-rotating shaft rotate synchronously with the adjusting knob. The column positioning assembly is connected to either the column-rotating shaft or the adjusting knob, and is used to prevent the column-rotating shaft from rotating.

The fine-tuning shaft is rotatably connected to the processing table. The adjusting knob is connected to one end of the fine-tuning shaft. The adjusting knob and the fine-tuning shaft rotate synchronously. The column positioning assembly is connected to the column rotating shaft, the fine-tuning shaft, or the adjusting knob. The large fine-tuning gear is connected to the column rotating shaft. The large fine-tuning gear and the column rotating shaft rotate synchronously. The small fine-tuning gear is connected to the fine-tuning shaft. The small fine-tuning gear and the fine-tuning shaft rotate synchronously. The large fine-tuning gear and the small fine-tuning gear mesh. The number of teeth of the large fine-tuning gear is greater than the number of teeth of the small fine-tuning gear.

[0011] According to some embodiments of the present invention, a drying mechanism is further included, the drying mechanism including an air source assembly, an air outlet channel is provided inside the support column, an air outlet communicating with the air outlet channel is provided on the top and / or side wall of the support column, and an air inlet is provided on the bottom or side wall of the support column, the air source assembly being connected to the air outlet channel through the air inlet.

[0012] According to some embodiments of the present invention, at least one of the first clamp and the second clamp is movably connected to the processing table.

[0013] According to some embodiments of the present invention, the cleaning mechanism further includes a washing positioning component, which is connected to the processing table and the cleaning table, and is used to position the processing table at an initial work position.

[0014] According to some embodiments of the present invention, the washing positioning assembly includes a blocked block and a blocking block. The blocked block is disposed on the processing table, and the blocking block is disposed on the washing table. The blocking block is used to abut against the blocked block, thereby preventing the processing table from rotating relative to the washing table.

[0015] According to some embodiments of the present invention, a coating mechanism is further included, the coating mechanism comprising a fixed platform, a brush, a lifting assembly, a translation assembly, and a paint assembly. The brush includes a brush rod and a brush head, the lower end of the brush rod is connected to the brush head, and the upper end of the brush rod is connected to the fixed platform. The fixed platform is disposed on the lifting assembly, the lifting assembly is disposed on the translation assembly, and the paint assembly is used to store paint. The lifting assembly and the translation assembly are used to coat the window of the laryngeal slide on the processing table with the paint after the brush head is coated with the paint to form the coating.

[0016] According to a second aspect of the present invention, a method for coating a laryngeal slide using the aforementioned laryngeal slide coating apparatus includes the following steps: placement, with the processing table in an initial position, placing multiple laryngeal slides one-to-one onto support columns, such that the support columns are inserted into the mounting cavity of the laryngeal slides and abut against the inner wall of the mounting cavity, thereby supporting the laryngeal slides; adjustment, rotating an adjustment knob to rotate the support columns, changing the tilt angle of the laryngeal slides, so that the viewing window of the laryngeal slides reaches a predetermined angle with the horizontal plane; fixing, with a first clamp abutting one side of the laryngeal slides and a second clamp abutting the other side of the laryngeal slides, clamping and fixing the laryngeal slides; cleaning, rotating the processing table forward, immersing the front end of the laryngeal slides in cleaning fluid; first drying, rotating the processing table in reverse, returning the processing table to the initial position, drying the laryngeal slides; applying a coating, applying a coating onto the viewing window of the laryngeal slides to form a coating; second drying, allowing the coating of the laryngeal slides to harden.

[0017] The laryngeal blade coating processing method according to the present invention has at least the following technical effects: by setting an adjustment step, the viewing angle position of the laryngeal blade can be adjusted, thereby improving the quality of the laryngeal blade viewing window coating processing. Moreover, the viewing positions of multiple laryngeal blades can be adjusted at one time, thereby improving work efficiency. The support column and clamp fixed in place of each laryngeal blade can ensure the stability of the laryngeal blade position, especially during cleaning, and can also separate multiple laryngeal blades from each other, preventing them from colliding and scratching each other during subsequent cleaning.

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, sidewalls refer to the left side wall and / or the right side wall.

[0038] In the description of this invention, "a plurality of" means two or more; "greater than," "less than," "exceeding," etc., are understood to exclude the number itself; and "above," "below," "within," etc., are understood to include the number itself. Where "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0039] In the description of this invention, it should be understood that "A is set on B" or "A is set on B" describes the connection or positional relationship between A and B, and does not mean that A is necessarily above B.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, movable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. "Bolt connection" and "screw connection" can be used interchangeably. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0041] It should be understood that multiple similar features in this invention are distinguished only by different prefixes. Therefore, in this invention, the feature names without distinguishing prefixes (or feature names with partial prefixes) are used to represent the combination of similar features of this type, such as using "clamp" to represent the first clamp and the second clamp. It should also be understood that the description of "laryngeal lens" in this invention is only to illustrate the structure of the laryngeal lens coating processing device and the function produced by the structure; "laryngeal lens" is not part of the structure of the laryngeal lens coating processing device.

[0042] Reference Figure 1 , Figure 6 and Figure 9According to an embodiment of the present invention, a laryngeal blade coating processing apparatus is used for processing a coating on a laryngeal blade 700 window 720. The laryngeal blade 700 is provided with a mounting cavity 710 (the mounting cavity 710 is used to accommodate a laryngeal endoscope lens), and a window 720 is provided at the front end of the laryngeal blade 700. The window 720 is located at the front end of the mounting cavity 710 (so that the lens can easily observe the patient's larynx from the window 720). The outside of the window 720 is used for coating. The apparatus includes a processing table 100, a fixing mechanism 200, and a cleaning mechanism 600.

[0043] Processing table 100. It should be understood that the table-like parts in this invention serve as the basic carrier for installing and fixing other components. It is a conceptual object and can be any object, such as a metal table, stone table, wooden table, plastic table, bracket, support plate, support frame, bearing seat, mounting plate, reinforcing rib, hook, or a combination of one or more components, serving a fixing and supporting function. It should be understood that the rear end (lower end in this embodiment) of the mounting cavity 710 has an opening to facilitate the entry and installation of the lens, thus providing an entry point for the support column 210; while the front end (upper end in this embodiment) of the mounting cavity 710 is closed, and the viewing window 720 is located on the outer surface of this closed end port.

[0044] The fixing mechanism 200 includes a support column 210, a first clamp 220, and a second clamp 230. The support column 210 is rotatably connected to the processing table 100. The support column 210 is used to extend into the mounting cavity 710 and abut against the inner wall of the mounting cavity 710 (thereby supporting the laryngeal lens 700). The first clamp 220 is disposed on the processing table 100 and is located on one side of the support column 210. The first clamp 220 is used to abut against one side of the laryngeal lens 700. The second clamp 230 is disposed on the processing table 100 and is located on the other side of the support column 210. The second clamp 230 is used to abut against the other side of the laryngeal lens 700. It should be understood that the clamp and the processing table 100 can be fixedly connected, or they can be detachably connected, slidably connected, etc., to facilitate adjustment of the distance between the first clamp 220 and the second clamp 230 to clamp and fix the laryngeal blade 700. It should be understood that the first clamp 220 and the second clamp 230 can clamp the laryngeal blade 700, thereby fixing the position of the laryngeal blade 700. In other words, when the laryngeal blade 700 is fixed, both the first clamp 220 and the second clamp 230 are interference-fitted with the laryngeal blade 700. It is important to understand that because the laryngeal blade 700 naturally has a certain curvature, it is tilted when its viewing window 720 is kept parallel to the horizontal plane. If the support column 210 is inserted into the laryngeal blade 700, it can support the blade and maintain its tilted position. Therefore, rotating the support column 210 and adjusting its tilt angle can adjust the angle of the viewing window 720 relative to the horizontal plane. Furthermore, it is important to understand that the curvature of laryngeal blades 700 may differ between different specifications. Therefore, when processing laryngeal blades 700 of different specifications, it is also necessary to rotate the support column 210 and adjust its tilt angle. It is also important to understand that when the processing table 100 has multiple fixing mechanisms 200, a portion of the first clamp 220 and the second clamp 230 can share the same part.

[0045] The cleaning mechanism 600 includes a cleaning table 610, which is equipped with a cleaning tank 611. A processing table 100 is located above the cleaning tank 611, and the processing table 100 and the cleaning table 610 are rotatably connected. The cleaning tank 611 is used to hold cleaning fluid (used to clean the laryngoscope blade 700). Before the coating step, the laryngoscope blade 700 needs to be free of dust, debris, small insects, hair, fibers, and other impurities on its viewing window 720 to prevent these impurities from being fixed on the viewing window 720 after the coating step, affecting both the visibility of the viewing window 720 and the stability of the coating. After the coating step, if the anti-fog material used in the coating is not easily soluble in water, it can be cleaned again for subsequent packaging and shipping. If the anti-fog material is easily soluble in water, it is best to thoroughly clean the laryngoscope blade 700 in the cleaning step before the coating step. It should be understood that an ultrasonic cleaning device can be installed in the cleaning tank 611 for better cleaning of the laryngoscope blade 700.

[0046] In this invention, by setting a support column 210 to rotatably connect to the processing table 100, the support column 210 can be rotated to adjust the angle and position of the laryngeal blade 700 supported by the support column 210, thereby adjusting the position of the viewing window 720 of the laryngeal blade 700 to ensure that the viewing window 720 has a predetermined angle with the horizontal plane. Under normal circumstances, it is necessary to ensure that the viewing window 720 is parallel to the horizontal plane so that the subsequent coating steps can be carried out smoothly and the coating quality can be guaranteed, preventing problems such as incomplete coating, unevenness, unevenness, and paint flowing and accumulating on one side of the viewing window 720 under gravity. The processing table 100 is rotatably connected above the cleaning tank 611. The processing table 100 can be flipped before and after the coating step, which facilitates the cleaning of the laryngeal lens 700, especially the viewing window 720 of the laryngeal lens 700, ensuring that the viewing window 720 is clean before and after the coating step. Moreover, since the laryngeal lens 700 is sleeved on the support column 210 and fixed by the first clamp 220 and the second clamp 230, the position of the laryngeal lens 700 is fixed, and multiple laryngeal lenses 700 can also be separated by a certain gap. Therefore, they will not collide with each other during cleaning, thus avoiding problems such as breakage, scratches, and coating damage.

[0047] Reference Figure 1 , Figure 3 and Figure 6In some embodiments of the present invention, a synchronous rotation mechanism 400 is also included. The synchronous rotation mechanism 400 includes a column-rotating shaft 410, an adjusting knob 420, and a column positioning assembly 430. Multiple fixing mechanisms 200 are provided. The column-rotating shaft 410 is rotatably connected to the processing table 100. All support columns 210 of the fixing mechanisms 200 are connected to the column-rotating shaft 410. The adjusting knob 420 is connected to one end of the column-rotating shaft 410. The support column 210 and the column-rotating shaft 410 rotate synchronously with the adjusting knob 420. The column positioning assembly 430 is connected to the column-rotating shaft 410 or the adjusting knob 420. The column positioning assembly 430 is used to stop the column-rotating shaft 410 from rotating (thereby positioning the angular position of the support column 210).

[0048] A processing table 100 is equipped with multiple support columns 210 of fixed mechanisms 200, allowing multiple laryngeal blades 700 to be processed simultaneously. A column-rotating shaft 410 connects to these multiple support columns 210, facilitating rotation of the shaft and thus rotating all the support columns 210 simultaneously. Therefore, during the placement step, multiple laryngeal blades 700 can be placed one-to-one on the support columns 210, supported by them. The inner wall of each laryngeal blade 700 abuts against the support column 210, maintaining its tilted position. The tilt angle of the support column 210 is correlated with the tilt angle of the laryngeal blade 700. In the subsequent adjustment step, rotating the adjustment knob 420 rotates the column-rotating shaft 410 synchronously, causing all the support columns 210 to rotate together, adjusting the tilt angle of all the support columns 210 simultaneously, thus adjusting the tilt angle of all the laryngeal blades 700 (viewing window 720 position). This adjustment method is highly efficient, eliminating the need for staff to adjust the tilt angle of each laryngeal blade 700 individually. This saves time and ensures that all laryngeal blades 700 are adjusted to the same tilt angle, reducing uncertainty during adjustment and standardizing the laryngeal blade coating process. It's important to understand that synchronous rotation means that the rotation of either blade will cause the other to rotate simultaneously; conversely, if the rotation of either blade is restricted (cannot rotate), the other will also be unable to rotate. Synchronous rotation can be achieved through fixed connections, integral connections, keyed connections, or molded connections.

[0049] Reference Figure 1 and Figure 5In some embodiments of the present invention, the column positioning assembly 430 includes a positioning spring 431, one end of the column rotation shaft 410 (fine-tuning shaft 440) is provided with an abutment cover 441, the adjustment knob 420 is located between the abutment cover 441 and the processing table 100, the adjustment knob 420 and the column rotation shaft 410 (fine-tuning shaft 440) are slidably connected, one end of the positioning spring 431 abuts against the abutment cover 441, and the other end of the positioning spring 431 abuts against the adjustment knob 420, the positioning spring 431 is used to press the adjustment knob 420 onto the processing table 100.

[0050] The column-rotating shaft 410 can be interference-fitted with other components (such as the processing table 100, or other additional components) to naturally fix its position, preventing it from rotating arbitrarily. This means the tilt angle adjusted to the support column 210 can be maintained and will not change arbitrarily. In this embodiment, under normal conditions, the positioning spring 431 presses the adjusting knob 420 against the processing table 100, thus preventing the adjusting knob 420 from rotating arbitrarily due to frictional resistance between it and the processing table 100, and consequently preventing the column-rotating shaft 410 from rotating arbitrarily. When it is necessary to rotate the column-rotating shaft 410 (during the adjustment step), the adjusting knob 420 is pulled, causing it to overcome the elastic force of the positioning spring 431 and move away from the processing table 100 (the positioning spring 431 is compressed), allowing the adjusting knob 420 and the column-rotating shaft 410 to rotate normally. It should be understood that the column positioning assembly 430 may also include a damping plate, at least one of the machining table 100 and the adjusting knob 420 that connects to the damping plate; thereby, the damping plate can enhance the frictional resistance between the adjusting knob 420 and the machining table 100. It should also be understood that the column positioning assembly 430 may be a set screw-like structure.

[0051] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the side wall of the adjustment knob 420 is provided with an indicator protrusion 421, and the processing table 100 is provided with a scale structure 120, the indicator protrusion 421 being used to point to the scale structure 120.

[0052] Furthermore, by precisely indicating the tilt angle of the support column 210 and the laryngeal lens 700 through the scale, the standardization of the laryngeal lens 700 coating process is further improved on the basis of the improved standardization of the column rotation shaft 410. Specifically, the scale corresponding to adjusting each specification of laryngeal lens 700 to the predetermined tilt angle can be predetermined. Thus, in the processing of laryngeal lens 700 of a certain specification, during the adjustment step, the operator does not need to pay extra attention to the position of the viewing window 720. They only need to rotate the adjustment knob 420 (while driving the support column 210 to rotate) so that the indicator protrusion 421 of the adjustment knob 420 points to the scale structure 120 (the corresponding scale) (corresponding to the laryngeal lens 700 of that specification). This ensures that the viewing window 720 is adjusted to the predetermined angle, which facilitates standardized and mechanized production processes, reduces manual control links, and thus reduces the impact of human error. It should be understood that the scale structure 120 can be a bar or dot structure formed by protrusions or depressions (and may also have specific scale numbers or different scale markings, such as uppercase and lowercase letters, Roman numerals, Chinese characters, numbers, etc.), and multiple scale structures are set (generally evenly distributed around the circumference of the axis of rotation) to facilitate the indication of angle position information.

[0053] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments of the present invention, the rotating mechanism 400 further includes a fine-tuning shaft 440, a large fine-tuning gear 450, and a small fine-tuning gear 460. The fine-tuning shaft 440 is rotatably connected to the processing table 100. An adjustment knob 420 is connected to one end of the fine-tuning shaft 440. The adjustment knob 420 and the fine-tuning shaft 440 rotate synchronously. A column positioning assembly 430 is connected to a column rotating shaft 410, the fine-tuning shaft 440, or the adjustment knob 420. The large fine-tuning gear 450 is connected to the column rotating shaft 410. The large fine-tuning gear 450 and the column rotating shaft 410 rotate synchronously. The small fine-tuning gear 460 is connected to the fine-tuning shaft 440. The small fine-tuning gear 460 and the fine-tuning shaft 440 rotate synchronously. The large fine-tuning gear 450 and the small fine-tuning gear 460 mesh. The number of teeth of the large fine-tuning gear 450 is greater than the number of teeth of the small fine-tuning gear 460.

[0054] The system includes a fine-tuning shaft 440, a large fine-tuning gear 450, and a small fine-tuning gear 460. When the adjustment knob 420 is rotated, the rotation amplitude of the column shaft 410 and the support column 210 is relatively smaller than that of the adjustment knob 420, thus achieving fine-tuning and improving adjustment accuracy. This also facilitates operation and reduces human error. Therefore, during the adjustment process, the adjustment knob 420 can be rotated (and the indicator protrusion 421 of the adjustment knob 420 can be made to point to the corresponding scale structure 120). The adjustment knob 420 drives the column shaft 410 to rotate via the fine-tuning shaft 440, the large fine-tuning gear 450, and the small fine-tuning gear 460.

[0055] In some embodiments of the present invention, a control mechanism is also included, the control mechanism including a processor, the column positioning assembly 430 including a column positioning motor, the column positioning motor being drivenly connected to the column rotation shaft 410, and the column positioning motor and the processor being electrically connected.

[0056] Similar to the aforementioned scale structure 120, based on the pre-set corresponding information for different specifications of laryngeal blades 700, during the adjustment step, the processor can control the column positioning motor to rotate by a predetermined angle, thereby rotating the column shaft 410 by a predetermined angle, and thus causing the support column 210 to rotate to a predetermined tilt angle. Through the processor and column positioning motor in the adjustment step, the coating processing of the laryngeal blade 700 becomes more intelligent and automated, further reducing human error and labor costs.

[0057] Reference Figure 1 and Figure 4 In some embodiments of the present invention, a drying mechanism is also included. The drying mechanism includes an air source assembly, an air outlet channel 211 is provided inside the support column 210, a column air outlet 212 communicating with the air outlet channel 211 is provided on the top and / or side wall of the support column 210, and a column air inlet 213 is provided on the bottom or side wall of the support column 210. The air source assembly is connected to the air outlet channel 211 through the column air inlet 213.

[0058] After the cleaning step, the laryngeal blade 700 needs to be dried again to facilitate the subsequent application of the coating. After the coating is applied, the coating on the viewing window 720 of the laryngeal blade 700 also needs to be dried and solidified. There are two ways to dry the laryngeal blade 700 again. One way is to leave it alone and let it air dry naturally, but this method takes a long time. Another way is to treat the laryngeal blade 700 with heat, air, or other methods to accelerate the drying process, such as blowing or drying. By providing air supply to the air outlet channel 211 of the support column 210, when the support column 210 is inserted into the mounting cavity 710 of the laryngeal lens 700, the gas exiting from the air outlet 212 of the support column 210 can enter the mounting cavity 710 of the laryngeal lens 700 and enter the interior of the laryngeal lens 700. On the one hand, this gas has a drying effect, which can dry the interior of the laryngeal lens 700. On the other hand, when the gas is hot, it can dry the interior of the laryngeal lens 700 and heat the overall temperature of the laryngeal lens 700, accelerating the drying of the exterior of the laryngeal lens 700 and the curing of the coating. Furthermore, when the ambient temperature and the temperature of the laryngeal lens 700 are very low, it will affect the bonding between the coating and the laryngeal lens 700. Therefore, the laryngeal lens 700 can be appropriately heated before the coating application step. It is important to understand that the air outlet 212 at the top of the support column 210 is crucial. Firstly, this outlet is located at the top of the support column 210, at the deepest point of the mounting cavity 710. Air exiting from this point allows for a complete flow of gas throughout the mounting cavity 710, facilitating the drying and heating of the entire laryngoscope blade 700. Secondly, this outlet is roughly aligned with the frontmost part of the mounting cavity 710, specifically below the viewing window 720. Gas blown from this point can directly reach below the viewing window 720, thus facilitating the application of airflow to that area. It is also important to understand that the air source and the air inlet 213 of the support column 210 are typically connected via a flexible hose, without affecting the rotation of the support column 210 or the processing table 100. The support column 210 of this invention serves both a supporting function and a connection to the air source, facilitating the drying of the laryngoscope blade, particularly the interior (mounting cavity) of the blade, which is difficult to achieve with ordinary drying equipment.

[0059] In some embodiments of the present invention, the drying mechanism further includes a switching valve, and the gas source assembly includes a normal temperature gas source and a hot gas source. Both the normal temperature gas source and the hot gas source are connected to the switching valve, and the switching valve is connected to the gas outlet channel 211 through the column inlet 213.

[0060] The drying mechanism needs to decide whether to blow room temperature gas or hot gas onto the support column 210 based on the actual situation. Specifically, generally, after the cleaning step and before the coating step, i.e., in the first drying step, a room temperature gas source can be connected to the air outlet channel 211 of the support column 210, and cold air (or room temperature air) can be blown from the air outlet 212 of the support column 210, thus facilitating the drying of the inside of the laryngeal lens 700 and saving energy costs. Alternatively, a hot gas source can be connected to the air outlet channel 211 of the support column 210, and hot air can be blown from the air outlet 212 of the support column 210, thus facilitating the drying of both the inside and outside of the laryngeal lens 700 and accelerating the drying of the outside of the laryngeal lens 700, reducing time costs. In special cases where the ambient temperature is low, a switching valve needs to be switched so that the hot gas source is connected to the air outlet channel 211 of the support column 210, and hot air is blown from the air outlet 212 of the support column 210, which can both dry the laryngeal lens 700 and appropriately raise the overall temperature of the laryngeal lens 700, facilitating the subsequent coating process of the viewing window 720. After the coating step, in the second drying step, if the ambient temperature is high, the coating can be allowed to dry naturally. However, if the ambient temperature is low, the hot air source and the air outlet 211 of the support column 210 need to remain connected, and hot air should be blown from the air outlet 212 of the support column 210 to maintain the laryngeal lens 700 at a suitable temperature to facilitate the drying of the coating. Therefore, the laryngeal lens coating processing device may also include a control mechanism, which includes a processor and a temperature sensor. The temperature sensor is set on the processing table 100 to detect the ambient temperature near the processing table 100. The temperature sensor and the switching valve (the switching valve is a solenoid valve) are electrically connected to the processor. When the temperature sensor detects that the ambient temperature is lower than the predetermined temperature, the switching valve switches in the first and second drying steps to connect the hot air source and the air outlet 211 of the support column 210. When the temperature sensor detects that the ambient temperature is higher than the predetermined temperature, the switching valve switches in the first and second drying steps to connect the ambient temperature air source and the air outlet 211 of the support column 210.

[0061] Figure 6 and Figure 8 In some embodiments of the present invention, at least one of the first clamp 220 and the second clamp 230 is movably connected to the processing table 100.

[0062] At least one of the first clamp 220 and the second clamp 230 is movably connected to the processing table 100. This facilitates the placement of the laryngeal blade 700 and makes the clamp suitable for holding laryngeal blades 700 of various sizes. The movable connection can be a snap-fit ​​connection 730, a threaded connection, a sliding connection, or other connection methods. In practice, for example, before the placement step, at least one clamp can be removed or moved away, and during the fixing step, the clamp can be reassembled or moved closer to hold and fix the laryngeal blade 700.

[0063] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments of the present invention, a clamping mechanism 300 is also included. The clamping mechanism 300 includes a sliding table 310, which is slidably connected to the processing table 100. A first clamping seat 220 is disposed on the sliding table 310, and a second clamping seat 230 is disposed on the processing table 100.

[0064] The sliding stage 310 slides, allowing the first clamp 220 to move closer to or further away from the second clamp 230, thereby clamping or releasing the laryngeal blade 700. Specifically, in the fixing step, the sliding stage 310 slides, causing the first clamp 220 to move closer to the second clamp 230, thereby clamping and fixing the laryngeal blade 700.

[0065] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments of the present invention, the clamping mechanism 300 further includes a screw 320 and a clamping knob 330. One end of the screw 320 is rotatably connected to the sliding table 310, and the screw 320 and the sliding table 310 move synchronously. The middle part of the screw 320 is threadedly connected to the processing table 100. The other end of the screw 320 is connected to the clamping knob 330, and the screw 320 and the clamping knob 330 rotate synchronously.

[0066] In the fixing step, rotating the clamping knob 330 causes the screw 320 to rotate, moving the screw 320 relative to the processing table 100. The screw 320 then moves the sliding table 310 relative to the processing table 100, causing the sliding table 310 to slide. The sliding table 310 then moves the first clamp 220 closer to the second clamp 230, thereby clamping and fixing the laryngeal lens 700. Moving the sliding table 310 in this manner has several advantages. First, the threaded connection between the screw 320 and the processing table 100 is relatively stable, and the screw 320 generally does not rotate arbitrarily, thus ensuring the stability of the laryngeal lens 700. Second, converting the rotation of the clamping knob 330 into the sliding of the sliding table 310 via the threaded connection facilitates the adjustment of the clamp position and provides a certain degree of fine-tuning capability. For every full rotation of the clamping knob 330, the sliding table 310 moves only one thread pitch.

[0067] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments of the present invention, the clamping mechanism 300 includes a set bolt 340, the middle part of which is threadedly connected to the processing table 100, and one end of the set bolt 340 is used to abut against the sliding table 310.

[0068] The presence of a set bolt 340 further enhances the stability of the sliding table 310, ensuring that the clamp can always hold and fix the laryngeal blade 700. Specifically, during the fixing process, after the laryngeal blade 700 is clamped and fixed, the set bolt 340 can be rotated so that one end of the set bolt 340 abuts against the sliding table 310, preventing the sliding table 310 from sliding further. It should be understood that the clamping mechanism 300 can also be equipped with a damping strip, which is located on the side wall of the sliding table 310. One end of the set bolt 340 abuts against the damping strip, increasing the clamping stability of the laryngeal blade 700.

[0069] Reference Figure 6 and Figure 8 In some embodiments of the present invention, the processing table 100 is provided with an adjustment groove 110, and the clamping mechanism 300 further includes a connecting bolt 350. The connecting bolt 350 passes through the adjustment groove 110 and is threadedly connected to the second clamp 230. The connecting bolt 350 and the second clamp 230 clamp the processing table 100.

[0070] The position of the clamp can be adjusted by adjusting the groove 110 and connecting bolts 350. It can be used alone (the first clamp 220 is fixedly connected to the processing table 100) or in combination with the above-mentioned first clamp 220 and sliding table 310 structure. In both cases, the position of the second clamp 230 can be adjusted to facilitate clamping the laryngeal lens 700.

[0071] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the cleaning mechanism 600 further includes a cleaning positioning component 620, which is connected to the processing table 100 and the cleaning table 610. The cleaning positioning component 620 is used to position the processing table 100 at the initial work position.

[0072] It should be understood that, under normal circumstances, when the processing table 100 is in the initial working position, the processing table 100 is roughly parallel to the cleaning table 610, or in other words, the processing table 100 is roughly in a horizontal state, that is, roughly parallel to the liquid level of the cleaning fluid in the cleaning tank 611, which facilitates the positioning and processing of the viewing window 720 of the laryngoscope blade 700. In practice, when the processing table 100 is flipped, i.e. during the cleaning step, there is little need to limit the position of the processing table 100, and the laryngoscope blade 700 can move freely in the cleaning solution. However, in other steps, it is necessary to strictly keep the processing table 100 in the initial position to facilitate the positioning and coating of the laryngoscope blade 700's viewing window 720. Specifically, in the adjustment step, it is necessary to ensure that the processing table 100 is in the initial position. This can be achieved by making the indicator protrusion 421 of the adjustment knob 420 point to the corresponding scale structure 120, thus ensuring that the laryngoscope blade 700's viewing window 720 reaches the predetermined angle position. Before the coating step, it is necessary to ensure that the processing table 100 returns to the initial position to ensure that the position of the laryngoscope blade 700 adjusted in the adjustment step remains unchanged, and that the viewing window 720 reaches the predetermined angle position.

[0073] Reference Figure 2 In some embodiments of the present invention, the washing positioning component 620 includes a blocked block 621 and a blocking block 622. The blocked block 621 is disposed on the processing table 100, and the blocking block 622 is disposed on the washing table 610. The blocking block 622 is used to abut against the blocked block 621, so that the processing table 100 no longer rotates relative to the washing table 610 (that is, the processing table 100 is positioned at the initial work position).

[0074] When the processing table 100 is rotated in the reverse direction during the first drying step, the blocking block 622 abuts against the blocked block 621, so that the processing table 100 no longer rotates relative to the cleaning table 610, thus positioning the processing table 100 in its initial position. The arrangement of the blocked block 621 and the blocking block 622 is very simple, but it can effectively ensure that the initial position of the processing table 100 remains unchanged.

[0075] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the washing positioning component 620 further includes a counterweight 623, which is disposed on one side of the processing table 100 by the stop block 621.

[0076] When the processing table 100 is in the initial position, the counterweight 623 is used to keep the processing table 100 naturally stationary in the initial position due to the gravity of the counterweight 623, and it will not move arbitrarily.

[0077] Reference Figure 2 In some embodiments of the present invention, one of the block 621 and the blocking block 622 is provided with a magnetic element, and the other is provided with a magnetic element or a ferromagnetic element.

[0078] Magnetic components are those that possess magnetism and can attract other objects, while ferromagnetic components are those that do not possess magnetism and cannot attract other objects, but can be attracted by magnets. Magnetic components can be magnets, and ferromagnetic components can be iron blocks. Similar to the arrangement of counterweight 623, the arrangement of magnetic and ferromagnetic components ensures that the processing table 100 remains stable in its initial position and does not move arbitrarily, especially under external forces, such as when a brush is applying a coating to the viewing window 720. Specifically, in the first drying step, the blocking block 622 abuts against the stop block 621. After the processing table 100 returns to its initial position, due to the above arrangement, it is attracted to the stop block 621 and the blocking block 622.

[0079] In some embodiments of the present invention, a control mechanism is also included, which includes a processor. The cleaning mechanism 600 also includes a cleaning motor, which is drivenly connected to the processing table 100, and the processor and the cleaning motor are electrically connected.

[0080] The processor controls the forward and reverse rotation of the cleaning motor, thereby controlling the forward and reverse rotation of the processing table 100, which facilitates the intelligent and automated processing of the laryngeal lens 700 coating.

[0081] In some embodiments of the present invention, a coating mechanism is also included. The coating mechanism includes a fixed platform, a brush, a lifting assembly, a translation assembly, and a paint assembly. The brush includes a brush rod and a brush head. The lower end of the brush rod is connected to the brush head, and the upper end of the brush rod is connected to the fixed platform. The fixed platform is disposed on the lifting assembly, and the lifting assembly is disposed on the translation assembly. The paint assembly is used to store paint. The lifting assembly and the translation assembly are used to (move the fixed platform) so that the brush head is coated with paint and then the paint is applied to the viewing window 720 of the laryngeal slide 700 on the processing table 100 to form a coating.

[0082] The coating process can be implemented manually by a worker applying the coating to the laryngoscope blade 700 (window 720), or automatically by the aforementioned coating mechanism. Specifically, the translation component moves the brush (fixed platform) above the paint container (paint bucket), the lifting component lowers the brush (fixed platform) so that the brush head is immersed in the paint stored in the paint container, the lifting component raises the brush (fixed platform), the translation component moves the brush (fixed platform) above the laryngoscope blade 700 (window 720), the lifting component lowers the brush (fixed platform) so that the brush head can contact the laryngoscope blade 700 (window 720), and the translation component (or another coating component) moves the brush slowly, thus applying the coating to the window 720. It should be understood that multiple brushes can be set on the fixed platform, and the arrangement of the brushes is the same as the arrangement of the multiple support columns 210 on the processing table 100, that is, when applying the coating, the brushes can correspond one-to-one with the laryngoscope blade 700.

[0083] In some embodiments of the present invention, the coating mechanism further includes a brush coating assembly, which is disposed on a fixed platform and the upper end of the brush rod is connected to the brush coating assembly.

[0084] The brush coating component can drive the brush to move slowly along a certain trajectory in the plane, thus facilitating the brush to apply a coating to the window 720.

[0085] In some embodiments of the present invention, the lifting assembly includes a lifting motor, a lifting screw, a lifting nut, and a lifting slide rail. The fixed platform and the lifting slide rail are slidably connected. The lifting nut is connected to the fixed platform. The lifting screw is rotatably connected to the lifting slide rail. The lifting screw and the lifting nut are threadedly connected. The lifting motor is driven by the lifting screw. The lifting slide rail is mounted on the translation assembly.

[0086] The motor drives the lead screw to rotate, which in turn moves the nut along the lead screw axis, thus moving the fixed platform (translation slide) on the slide rail. This type of structure is simple in lifting and translating, convenient to control and operate, and is a commonly used structure in existing technology. It should be understood that the lifting and translating components can also be other structures, such as a structure in which a belt drives a slider to move along the slide rail, a rotational translation structure in which a motor controls the rotation of a turntable, or a movement structure driven by a cylinder.

[0087] In some embodiments of the present invention, the translation component includes a translation motor, a translation screw, a translation nut, a translation slide and a translation rail, a lifting rail is disposed on the translation slide, the translation slide and the lifting rail are slidably connected, the translation nut is connected to the translation slide, the translation screw is rotatably connected to the translation rail, the translation screw and the translation nut are threadedly connected, and the translation motor is driven to connect to the translation screw.

[0088] The translation component can be referenced from the above-mentioned lifting component, and will not be repeated here.

[0089] In some embodiments of the invention, the coating assembly includes a coating bucket for storing coating.

[0090] Paint buckets are common paint storage containers, making it convenient to store paint.

[0091] In some embodiments of the present invention, the coating assembly further includes a heating module connected to the coating bucket, the heating module being used to heat the coating bucket.

[0092] In some special cases, such as when the ambient temperature is very low, a heating module can be used to heat the paint bucket, which preheats the paint and facilitates the bonding of the paint and the laryngeal blade 700.

[0093] Reference Figure 1 and Figure 6In some embodiments of the present invention, the processing table 100 is provided with a clearance recess 130, and the rear end of the laryngeal blade 700 is provided with a buckle 730, and the clearance recess 130 is used to accommodate the buckle 730.

[0094] Some laryngeal blades 700 have a latch 730 at the rear end. Therefore, a clearance recess 130 is provided on the processing table 100 to make room for the latch 730, which facilitates the placement of the laryngeal blade 700.

[0095] Reference Figure 1 and Figure 6 According to the laryngeal blade coating processing method of the present invention, using the aforementioned laryngeal blade coating processing apparatus, the method includes the following steps:

[0096] Placement: With the processing table 100 in the initial position, place multiple laryngeal blades 700 one by one onto the support column 210, so that the support column 210 is inserted into the mounting cavity 710 of the laryngeal blade 700 and abuts against the inner wall of the mounting cavity 710, thereby supporting the laryngeal blade 700.

[0097] Adjust the position by rotating the adjustment knob 420, which drives the support column 210 to rotate, changing the tilt angle of the laryngeal blade 700 so that the viewing window 720 of the laryngeal blade 700 reaches a predetermined angle with the horizontal plane (or in other words, the viewing window 720 reaches a predetermined angle position); under normal circumstances, the predetermined angle is zero, that is, the viewing window 720 is parallel to the horizontal plane.

[0098] The first clamp 220 abuts against one side of the laryngeal blade 700, and the second clamp 230 abuts against the other side of the laryngeal blade 700, thus clamping and fixing the laryngeal blade 700.

[0099] Cleaning: Rotate the processing table 100 in the forward direction so that the front end of the laryngeal blade 700 is immersed in the cleaning solution.

[0100] First drying: Rotate the processing table 100 in the reverse direction so that the processing table 100 returns to the initial position and waits for the laryngeal blade 700 to dry.

[0101] Apply a coating by brushing paint onto the viewing window 720 of the laryngoscope blade 700 to form a coating.

[0102] The second drying process involves waiting for the 700 coating on the laryngeal blade to dry completely.

[0103] By setting up an adjustment step, the viewing angle 720 of the laryngeal blade 700 can be adjusted, improving the quality of the coating processing of the viewing window 720 of the laryngeal blade 700. Furthermore, the positions of the viewing windows 720 of multiple laryngeal blades 700 can be adjusted simultaneously, improving work efficiency. The support column 210 and clamps fix the position of each laryngeal blade 700, ensuring positional stability, especially during cleaning, and preventing arbitrary movement. They also separate multiple laryngeal blades 700 from each other, preventing collisions and scratches during subsequent cleaning. It should be understood that the placement, adjustment, fixing, cleaning, first drying, coating application, and second drying steps are performed sequentially. It should also be understood that after the second drying step, the cleaning and first drying steps can be performed again. Finally, the laryngeal blades 700 can be removed, sterilized, packaged, and prepared for sale. The changes made to each step depending on the degree of improvement in the laryngeal blade coating processing device have been mentioned in the relevant sections above and will not be repeated here. It is important to understand that in the description of this invention, "forward rotation" and "reverse rotation" do not refer to a specific direction of rotation. The prefixes "forward" and "reverse" only indicate that the two components (or a component in two cases) rotate in opposite directions. They are not related to the actual rotation standard of the component. In practice, forward rotation can be counterclockwise or clockwise, and can be the forward or reverse rotation state specified in the component's operation manual (or instruction manual, etc.). The same applies to reverse rotation. During the cleaning step, the front end of the laryngeal blade 700 (i.e., the viewing window) will definitely be immersed in the cleaning solution for cleaning, facilitating the coating processing of the viewing window. For subsequent factory sales (and when the anti-fog coating material is hydrophilic), the laryngeal blade 700 can also be completely immersed in the cleaning solution during this step for thorough cleaning, ensuring the laryngeal blade 700 is clean and ready for direct packaging and sale.

[0104] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
