Description

Technical Field

[0001] The present disclosure relates to the field of biomedical engineering industry, and in particular to a film coating device. Background Art

[0002] With the continuous advancement of science and technology, more and more medical devices are used for auxiliary treatment of the human body. Among these medical devices, there are many implantable medical devices that need to be implanted in the human body to exert their functions. When producing these implantable medical devices, they usually need to be biocompatible. For example, a continuous blood glucose monitor can monitor the blood sugar level of the human body by partially implanting the sensor into the subcutaneous tissue of the subject. In order to reduce the immune response caused by the implantation of the sensor into the subcutaneous tissue, when producing a continuous blood glucose monitor, it is often necessary to coat the sensor with a biocompatible film, which can generally be coated with a pull-type coating device.

[0003] In the prior art, during the coating process of the sensor, the sensor mounted on the pull-type coating device can be immersed in the pre-prepared sol, and then the sensor can be pulled out of the sol. At this time, a liquid film can be formed on the surface of the sensor to be coated. With the rapid evaporation of the solvent in the sol, a thin film can be formed on the surface of the sensor to be coated that has been soaked in the sol. In this process, the sensors can be coated in batches by mounting multiple sensors on the pull-type coating device.

[0004] However, when multiple sensors are assembled on the pull-type coating equipment, each sensor is an independent part. Therefore, it is difficult to ensure the consistency of fixation during the process of fixing the multiple sensors separately, and thus the consistency of coating the multiple sensors at the same time needs to be improved. Summary of the invention

[0005] The present disclosure is proposed in view of the above-mentioned state of the prior art, and its object is to provide a coating device that can improve the consistency of coating a plurality of sensors at the same time.

[0006] To this end, the present disclosure provides a coating device, which is a coating device for coating multiple sensors, wherein the multiple sensors are connected in sequence to form a sensor array, and the upper surfaces of the sensors are in the same plane, the sensors include a portion to be coated, and the coating device includes a carrying mechanism and a liquid holding mechanism; the carrying mechanism includes a carrying portion for fixing the sensor array; the liquid holding mechanism includes a plurality of liquid tanks of the same shape, and the liquid tanks are used to hold coating liquid; the liquid holding mechanism moves relative to the carrying mechanism so that the portion to be coated of each sensor fixed on the carrying portion is immersed in the coating liquid in the liquid tank and leaves the coating liquid in the liquid tank, so as to form a film layer on the portion to be coated of each sensor.

[0007] In the coating equipment involved in the present disclosure, a plurality of sensors are connected in sequence to form a sensor array, and the upper surfaces of each sensor are in the same plane, so that the surface of the sensor array can be flat. When the sensor array is fixed to a supporting mechanism, the parts to be coated of the plurality of sensors can be neatly arranged on the supporting mechanism. Therefore, when the parts to be coated are immersed in the coating liquid in a liquid tank of the same shape and leave for coating, the consistency of coating the plurality of sensors at the same time can be improved.

[0008] In addition, in the coating device of the present disclosure, optionally, the carrier includes a substrate, and the sensor array is fixed to the substrate in a manner of protruding from an edge of the substrate, thereby facilitating coating of the sensor array.

[0009] In addition, in the coating device involved in the present disclosure, optionally, the substrate has a first limiting portion and a second limiting portion, and the first limiting portion cooperates with the second limiting portion to limit the sensor array in the horizontal direction and the vertical direction. In this case, when the sensor array is fixed to the bearing portion, the movement of the sensor array in the horizontal direction and the vertical direction can be effectively limited, thereby improving the consistency of coating the sensor array.

[0010] In addition, in the coating device involved in the present disclosure, optionally, the distance between the first limiting portion and the edge of the substrate in the vertical direction is less than a preset value, and the second limiting portion has a preset length in the horizontal direction. In this case, after the first limiting portion supports the sensor array, the portion of the sensor to be coated can protrude from the edge of the substrate, thereby facilitating the coating of the sensor array. In addition, when the sensor array is fixed to the substrate, the second limiting portion can limit the horizontal movement of two adjacent sensors in the sensor array, and thus the second limiting portion can limit the horizontal movement of the entire sensor array.

[0011] In addition, in the coating device involved in the present disclosure, optionally, the bearing part includes a clip, the clip is detachably coupled to the substrate, and when the clip is coupled to the substrate, the sensor array is located between the clip and the substrate. In this case, by using the clip detachably coupled to the substrate, on the one hand, when the clip is coupled to the substrate, the stability of the sensor array fixed to the bearing part can be improved; on the other hand, when the clip is detached from the substrate, it is easy to replace the sensor array that has not been coated.

[0012] In addition, in the coating device involved in the present disclosure, optionally, the substrate includes a housing area for accommodating the sensor array, a magnet is arranged in the housing area, and the clip is made of a ferromagnetic material and can be coupled with the housing area. In this case, the clip can be detachably coupled to the substrate by magnetic attraction. Compared with other coupling methods (such as threaded tightening methods), the magnetic attraction method can make it difficult for the bearing part to be too tight or too loose when fixing the sensor array, thereby making it difficult for the sensor array to be offset or deformed, thereby improving the consistency of coating the sensor array.

[0013] In addition, in the coating device involved in the present disclosure, optionally, the supporting mechanism also includes a main body, the number of the supporting parts is multiple and the supporting part is detachably mounted on the main body. In this case, the supporting part can be disassembled from the main body so as to facilitate the supporting part to be laid flat to assemble the sensor array, which can be beneficial to improve the accuracy and efficiency of assembly. In addition, when assembling the sensor array, the supporting part is first disassembled from the main body, and the supporting part is assembled with the main body after the sensor array and the supporting part are fixed. Compared with directly assembling the sensor array on the non-detachable supporting part, less operating space can be reserved between the multiple supporting parts. In other words, more supporting parts can be set on the supporting mechanism in which the supporting part is detachably mounted on the main body, thereby further improving the efficiency of coating the sensor array.

[0014] In addition, in the coating device involved in the present disclosure, optionally, the main body includes a fixing member and a locking member, and when the bearing part is assembled with the main body, the fixing member abuts against one end of the bearing part, and the locking member abuts against the other end of the bearing part. In this case, by making the fixing member and the locking member abut against the two ends of the bearing part respectively, the bearing part can be prevented from being easily separated from the main body, thereby improving the stability of coating the sensor array.

[0015] In addition, in the coating device involved in the present disclosure, optionally, the locking member has a locking state that cooperates with the fixing member to lock the bearing part and an unlocking state opposite to the locking state. When the bearing part and the main body are assembled, the locking member in the locking state abuts against the bearing part. When the locking member is acted in a direction away from the fixing member, the locking member changes from the locking state to the unlocking state. In this way, the convenience of disassembling the bearing part and the main body can be improved.

[0016] In addition, in the coating device involved in the present disclosure, optionally, the fixing member includes a curved surface in contact with the bearing portion, the locking member includes a curved surface in contact with the bearing portion, the bearing portion includes a first recess cooperating with the fixing member and a second recess cooperating with the locking member, and when the bearing portion is assembled with the main body, the curved surface of the fixing member abuts against the first recess, and the curved surface of the locking member abuts against the second recess. In this case, the stability of the fixing member and the locking member when they abut against the bearing portion respectively can be improved, thereby improving the stability of the bearing portion and the main body when they are assembled, and the stably assembled bearing portion and main body can make the sensor array less likely to shift during coating, thereby improving the consistency of the coating.

[0017] In addition, in the coating device involved in the present disclosure, optionally, at one end of the bearing part close to the second recess, the bearing part has a guide surface adjacent to the second recess, and the guide surface is configured to contact the curved surface of the locking member to guide the locking member to the unlocked state. In this case, when the bearing part is assembled with the main body, one end of the bearing part is first abutted against the fixing member, and then the other end of the bearing part is pressed downward toward the main body, so that a part of the pressure applied to the bearing part toward the main body can be transferred to the action applied to the locking member in a direction away from the fixing member through the guiding action of the guide surface, so that the locking member can be changed from the locked state to the unlocked state without directly acting on the locking member, thereby improving the convenience of assembling the bearing part and the main body.

[0018] In addition, in the coating device involved in the present disclosure, optionally, the number of the locking members is consistent with the number of the bearing parts, and the bearing mechanism further includes an applying part, and the applying part is coupled with the plurality of the locking members to operate the plurality of the locking members in batches. In this case, it is convenient to convert the plurality of locking members from a locked state to an unlocked state in batches, so that the plurality of bearing parts can be assembled with the main body at one time, thereby further improving the efficiency of coating the plurality of sensors.

[0019] In addition, in the coating device involved in the present disclosure, optionally, the bearing part includes a sealing ring made of an elastic material, a groove is formed in the accommodating area of ​​the substrate, and the sealing ring is arranged in the groove and protrudes from the surface of the substrate. In this case, when the clip is coupled to the substrate, the clip can make the sensor array close to the substrate, and the sealing ring will produce a certain degree of deformation under the action of force and have a rebound tendency acting on the sensor array, that is, it can make the sensor array close to the clip. Through the action of close contact in two relative directions, the waterproof performance of the bearing part to the sensor array can be improved.

[0020] In addition, in the coating device of the present disclosure, optionally, the liquid tank has a storage space for storing the coating liquid, the storage space is truncated cone-shaped, and the cross-sectional area at the opening of the liquid tank is larger than the cross-sectional area at the bottom. In this case, when the liquid tank is filled with liquid, by injecting the coating liquid into the liquid tank deviating from the center line of the storage space, the coating liquid can flow into the bottom of the liquid tank along the wall of the liquid tank and gradually fill the opening of the liquid tank, thereby reducing the air remaining in the coating liquid in the liquid tank, thereby improving the quality of the coating.

[0021] According to the present disclosure, it is possible to provide a coating device that improves the consistency of coating a plurality of sensors at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, the same symbols are assigned to the same components, and repeated descriptions are omitted. In addition, the accompanying drawings are only schematic diagrams, and the ratio of the dimensions of the components or the shapes of the components may be different from the actual ones.

[0034] It should be noted that the terms "including" and "having" and any variations thereof in the present disclosure, such as a process, method, system, product or device that includes or has a series of steps or units, are not necessarily limited to those steps or units clearly listed, but may include or have other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] It should be noted that, in this article, relative position and relative direction terms such as "above", "towards above", "below", "towards downward", "up and down direction", "left side", "towards the left side", "left side", "towards the left", "right side", "towards the right side", "right side", "towards the right", "left and right direction", "front", "towards the front", "back", "towards the back", "front and back direction" are used with reference to the normal operating posture and should not be considered restrictive.

[0036] The present disclosure relates to a coating device, which is a coating device for coating multiple sensors. In other words, the coating device involved in the present disclosure can perform batch coating on multiple sensors at the same time. In some examples, the sensor may refer to a sensor used in a continuous blood glucose monitor. In some examples, the sensor may also refer to a sensor in other implantable medical devices. In the present disclosure, the coating device may sometimes also be referred to as a batch coating device, a sensor coating device, or a coating apparatus.

[0037] Hereinafter, the coating equipment involved in the present disclosure will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 is a schematic diagram showing the structure of the sensor array 1 involved in the example of the present disclosure. It should be noted that, Figure 1 The number of sensors 10 included in the sensor array 1 shown is only illustrative and should not be considered as a substantial limitation on the number of sensors 10 that may be included in the actual sensor array 1 .

[0039] See also Figure 1 In some examples, a plurality of sensors 10 may be connected in sequence to form a sensor array 1. In other words, the sensor array 1 may include a plurality of sensors 10 connected in sequence.

[0040] See also Figure 1 In some examples, the sensor 10 may include a portion 110 to be coated.

[0041] In some examples, the upper surfaces of the sensors 10 in the sensor array 1 may be in the same plane. In other words, the line connecting the lowest points and the line connecting the highest points of the sensors 10 in the sensor array 1 may be parallel to each other ( Figure 1 The two dotted lines L in FIG. 2 schematically illustrate this relationship).

[0042] See also Figure 1 In some examples, two adjacent sensors 10 may be connected via a connecting portion 11 , or the sensor array 1 may include a connecting portion 11 connecting two adjacent sensors 10 .

[0043] In some examples, the sensor array 1 can be formed by cutting a predetermined path on the substrate through a pre-set program. In other words, the sensor array 1 can be formed in one piece. In this case, it is helpful to improve the consistency between the multiple sensors 10 in the sensor array 1. In some examples, the connecting portion 11 and the sensor 10 can be made of the same material.

[0044] In some examples, the distance between two adjacent sensors 10 may be no greater than a preset distance w (see Figure 1 In some examples, the preset distance w may be a distance at which two adjacent sensors 10 do not come into contact with each other.

[0045] In some examples, the maximum length of the connection portion 11 may be no greater than the preset distance w. In this case, the sensor array 1 per unit length can include more sensors 10, which can improve the compactness of the sensors 10 in the sensor array 1, and further improve the efficiency of coating the multiple sensors 10.

[0046] In some examples, the connection part 11 can be separated from the sensor 10 by cutting. In some examples, after the sensor array 1 is coated, the connection part 11 can be separated from the sensor 10. In some examples, the sensor array 1 can be coated by the coating device 2 involved in the present disclosure.

[0047] Figure 2 1 is a schematic diagram showing the entirety of the supporting mechanism 21 involved in the example of the present disclosure.

[0048] In some examples, the coating device 2 may include a carrying mechanism 21, which may be used to carry the sensor array 1. In some examples, the carrying mechanism 21 may carry multiple sensor arrays 1. In this case, the sensor array 1 itself may include multiple sensors 10, and the efficiency of the coating device 2 in coating multiple sensors 10 simultaneously may be further improved by having the carrying mechanism 21 carry multiple sensor arrays 1.

[0049] In some examples, the carrying mechanism 21 may include a carrying portion 211 , and the carrying portion 211 may be used to fix the sensor array 1 .

[0050] In some examples, there may be a plurality of carrier portions 211. For example, there may be 2, 3, 5, 10 or more carrier portions 211.

[0051] Figure 3 2 is a schematic diagram showing the structure of the sensor array 1 involved in the example of the present disclosure being fixed to the carrier 211 . Figure 4 is an exploded view showing the bearing portion 211 involved in the example of the present disclosure. Figure 4 The sizes of the first limiting portion 2111 a and the second limiting portion 2111 b are only schematic, and their actual sizes can be adaptively adjusted and set based on the actual size of the sensor array 1 .

[0052] In some examples, the carrier 211 may include a substrate 2111. The sensor array 1 may be fixed to the substrate 2111 in a manner of protruding from an edge of the substrate 2111 (see Figure 3 ). Thus, the sensor array 1 can be easily coated.

[0053] In some examples, the substrate 2111 may be made of an aluminum alloy material.

[0054] In some examples, the substrate 2111 may have a first stopper 2111a (see Figure 4 ). The first limiting portion 2111a may protrude from the surface of the substrate 2111. In some examples, the first limiting portion 2111a may support the sensor array 1.

[0055] In some examples, the length of the first limiting portion 2111a may match the length of the sensor array 1 , thereby being able to support more sensors 10 .

[0056] In some examples, the length of the first position limiter 2111a may not match the length of the sensor array 1. In some examples, the number of the first position limiters 2111a may be multiple. For example, the number of the first position limiters 2111a may be 2, 3, 4, 5, 6 or more. In some examples, the multiple first position limiters 2111a may be arranged at intervals. In this case, since the sensor array 1 formed by connecting the multiple sensors 10 via the connecting portion 11 has a certain rigidity, the multiple first position limiters 2111a arranged at intervals can still support the multiple sensors 10, and can also save the manufacturing materials of the first position limiters 2111a.

[0057] In some examples, the distance between the first limiter 2111a and the edge of the substrate 2111 along the vertical direction may be less than a preset value. Specifically, the distance between the first limiter 2111a and the upper edge of the substrate 2111 along the vertical direction may be less than a preset value. In this case, after the first limiter 2111a supports the sensor array 1, the portion to be coated 110 of the sensor 10 can protrude from the edge of the substrate 2111, thereby facilitating the coating of the sensor array 1.

[0058] In some examples, the preset value may be determined by the actual length of the portion to be coated 110 and the size of the substrate 2111 .

[0059] In some examples, the substrate 2111 may have a second limiting portion 2111b (see Figure 4 ). The second limiting portion 2111b may protrude from the surface of the substrate 2111. In some examples, when the sensor array 1 is fixed to the substrate 2111, the second limiting portion 2111b may be located between two adjacent sensors 10 in the sensor array 1.

[0060] In some examples, the second limiter 2111b may have a preset length in the horizontal direction. In this case, when the sensor array 1 is fixed to the substrate 2111, the second limiter 2111b can limit the movement of two adjacent sensors 10 in the sensor array 1 in the horizontal direction, and thus the second limiter 2111b can limit the movement of the entire sensor array 1 in the horizontal direction.

[0061] In some examples, the preset length may be no greater than the preset distance w.

[0062] In some examples, the preset length may be the distance between two adjacent sensors 10 in the sensor array 1 .

[0063] In some examples, when the sensor array 1 is fixed to the substrate 2111 , the second limiting portion 2111 b may not be located between two adjacent sensors 10 in the sensor array 1 .

[0064] In some examples, the number of the second limiting portions 2111 b may be multiple, for example, the number of the second limiting portions 2111 b may be 2, 3, 4, 5, 6 or more.

[0065] In some examples, the number of the second position-limiting portions 2111b may be two. In some examples, the distance between the two second position-limiting portions 2111b in the horizontal direction may be a set distance. In some examples, the set distance may be equal to the length of the sensor array 1. In this case, when the sensor array 1 is fixed to the substrate 2111, the two second position-limiting portions 2111b may be located at both ends of the sensor array 1 and contact the sensors 10 at both ends of the sensor array 1, respectively, thereby limiting the movement of the entire sensor array 1 in the horizontal direction.

[0066] Figure 5 2 is a schematic diagram showing the first limiting portion 2111a and the second limiting portion 2111b involved in the example of the present disclosure cooperating to limit the sensor array 1. In order to better illustrate the limiting of the sensor array 1, Figure 5 Lines that might affect the description are omitted, and Figure 5 The sensor array 1 in the embodiment includes two sensors 10. Figure 5 The dotted line X in the figure schematically depicts the aforementioned horizontal direction, and the dotted line Y schematically depicts the aforementioned vertical direction.

[0067] In some examples, the first limiting portion 2111a can cooperate with the second limiting portion 2111b to limit the sensor array 1 in the horizontal direction and the vertical direction. Figure 5 When the sensor array 1 is fixed to the substrate 2111, the movement of the sensor array 1 in the vertical direction will be limited by the first limiter 2111a or the second limiter 2111b, and the movement of the sensor array 1 in the horizontal direction will be limited by the second limiter 2111b. In this case, when the sensor array 1 is fixed to the bearing portion 211, the movement of the sensor array 1 in the horizontal and vertical directions can be effectively limited, thereby improving the consistency of coating the sensor array 1.

[0068] See also Figure 4In some examples, the carrier 211 may include a clip 2112, and the clip 2112 may be detachably coupled to the substrate 2111. In some examples, when the clip 2112 is coupled to the substrate 2111, the sensor array 1 may be located between the clip 2112 and the substrate 2111. In this case, by using the clip 2112 detachably coupled to the substrate 2111, on the one hand, when the clip 2112 is coupled to the substrate 2111, the stability of the sensor array 1 fixed to the carrier 211 can be improved; on the other hand, when the clip 2112 is detached from the substrate 2111, it is easy to replace the sensor array 1 that is not coated.

[0069] In some examples, a notch may be provided on the clip 2112, and the position of the notch may correspond to the contact position of the sensor 10 in the sensor array 1. In this case, the performance test of the sensor 10 can be performed through the notch of the clip 2112 after the sensor array 1 is coated.

[0070] In some examples, the substrate 2111 may include a receiving area for receiving the sensor array 1. In other words, when the sensor array 1 is fixed to the carrier 211, the sensor array 1 may be in the receiving area.

[0071] In some examples, the clip 2112 can be coupled to the accommodating area. In some examples, a magnet can be provided in the accommodating area. In some examples, the clip 2112 can be made of a ferromagnetic material. In this case, the clip 2112 can be detachably coupled to the substrate 2111 by magnetic attraction. Compared with other coupling methods (such as threaded tightening methods), the magnetic attraction method can make the bearing portion 211 less likely to be too tight or too loose when fixing the sensor array 1, thereby making the sensor array 1 less likely to be offset or deformed, thereby improving the consistency of coating the sensor array 1.

[0072] In some examples, the clip 2112 can be made of an iron alloy. In some examples, the clip 2112 can be made of spring steel.

[0073] See also Figure 3In some examples, a groove 2111c may be formed in the accommodating area of ​​the substrate 2111. In some examples, the bearing portion 211 may include a sealing ring 2113. In some examples, the sealing ring 2113 may be disposed in the groove 2111c and protrude from the surface of the substrate 2111. In some examples, the sealing ring 2113 may be made of an elastic material. In this case, when the clip 2112 is coupled to the substrate 2111, the clip 2112 can make the sensor array 1 close to the substrate 2111, and the sealing ring 2113 will deform to a certain extent under the action of force and have a rebound tendency acting on the sensor array 1, that is, it can make the sensor array 1 close to the clip 2112. Through the action of close contact in two relative directions, the waterproof performance of the bearing portion 211 to the sensor array 1 can be improved.

[0074] In some examples, the size of the sealing ring 2113 can match the size of the clip 2112. In some examples, the outer peripheral contour of the clip 2112 can be comparable to the outer peripheral contour of the sealing ring 2113.

[0075] In some examples, the sealing ring 2113 can be made of plastic.

[0076] In some examples, the sealing ring 2113 may be made of silicone. In some examples, the sealing ring 2113 may be made of silicone with a Shore A hardness of 10 to 60 degrees, for example, the sealing ring 2113 may be made of silicone with a Shore A hardness of 10, 20, 40 or 60 degrees. In some examples, preferably, the sealing ring 2113 may be made of silicone with a Shore A hardness of 20 degrees. In this case, the sealing ring 2113 can be made not too soft or too hard, thereby further improving the waterproof performance of the bearing part 211 to the sensor array 1.

[0077] Figure 6 2 is a schematic diagram showing a main body portion 212 according to an example of the present disclosure. Fig. 7A This is a diagram showing the Figure 6 An enlarged schematic diagram of area a in the middle; Figure 7B This is a diagram showing the Figure 6 Enlarged schematic diagram of area b.

[0078] In some examples, the bearing mechanism 21 may further include a main body 212, and the bearing part 211 may be detachably mounted on the main body 212. In some examples, the number of the bearing parts 211 may be multiple. In this case, the bearing part 211 can be detached from the main body 212 so as to facilitate the bearing part 211 to be laid flat to assemble the sensor array 1, which can help improve the accuracy and efficiency of assembly. In addition, when assembling the sensor array 1, the bearing part 211 is first detached from the main body 212, and the bearing part 211 is assembled with the main body 212 after the sensor array 1 is fixed to the bearing part 211. Compared with directly assembling the sensor array 1 on the non-detachable bearing part 211, less operating space can be reserved between multiple bearing parts 211. In other words, more bearing parts 211 can be set on the bearing mechanism 21 in which the bearing part 211 is detachably mounted on the main body 212, thereby further improving the efficiency of coating the sensor array 1.

[0079] See also Figure 6 In some examples, the main body 212 may include a first bottom plate 2121 .

[0080] See also Fig. 7A In some examples, the main body 212 may include a fixing member 2122. The fixing member 2122 may be fixed to the first bottom plate 2121.

[0081] In some examples, there may be a plurality of fixing elements 2122. The plurality of fixing elements 2122 may be arranged in an array.

[0082] In some examples, the number of the fixing members 2122 may be consistent with the number of the carrying portions 211. For example, the number of the fixing members 2122 may be 2, 3, 5, 10 or more.

[0083] In some examples, the fixture 2122 may be cylindrical.

[0084] See also Figure 7B In some examples, the main body 212 may include a locking member 2123. The locking member 2123 may be movable relative to the first bottom plate 2121.

[0085] In some examples, there may be a plurality of locking members 2123. The plurality of locking members 2123 may be arranged in an array.

[0086] In some examples, the number of locking members 2123 may be consistent with the number of bearing portions 211. For example, the number of locking members 2123 may be 2, 3, 5, 10 or more.

[0087] In some examples, when the bearing portion 211 is assembled with the main body 212, the fixing member 2122 may abut against one end of the bearing portion 211, and the locking member 2123 may abut against the other end of the bearing portion 211. In this case, by making the fixing member 2122 and the locking member 2123 abut against the two ends of the bearing portion 211, respectively, the bearing portion 211 is not easily separated from the main body 212, thereby improving the stability of coating the sensor array 1.

[0088] In some examples, the locking member 2123 may have a locked state in which it cooperates with the fixing member 2122 to lock the bearing portion 211. Specifically, when the locking member 2123 moves to a certain extent relative to the first bottom plate 2121 and approaches the fixing member 2122, the locking member 2123 may abut against the bearing portion 211 and exert a certain force, thereby cooperating with the fixing member 2122 to lock the bearing portion 211.

[0089] In some examples, the locking member 2123 may have an unlocking state opposite to the locking state. Specifically, when the locking member 2123 moves to a certain extent relative to the first bottom plate 2121 away from the fixing member 2122 , the carrying portion 211 may be detached from the main body 212 .

[0090] In some examples, before the carrying portion 211 is assembled with the main body portion 212 , the locking member 2123 may be in a locked state.

[0091] Figure 8 Schematic diagram showing the working principle of the locking member 2123 involved in the example of the present disclosure.

[0092] In order to better illustrate the working principle of the locking member 2123, Figure 8 The components involved are simplified.

[0093] In some examples, when the bearing portion 211 is assembled with the main body portion 212 , the bearing portion 211 may be located between the fixing member 2122 and the locking member 2123 .

[0094] In some examples, the locking member 2123 may include a movable end 2123a. The movable end 2123a may abut against the bearing portion 211 (see Figure 8 ).

[0095] In some examples, the locking member 2123 may include a pivot end 2123b. The pivot end 2123b may be connected to the movable end 2123a (see Figure 8 ).

[0096] In some examples, the fulcrum end 2123b can be fixed to the first bottom plate 2121, and the movable end 2123a can move toward or away from the fixing member 2122 with the fulcrum end 2123b as a fulcrum. Thus, the locking member 2123 can be in a locked state or an unlocked state.

[0097] In some examples, the movement of the movable end 2123a with the fulcrum end 2123b as the fulcrum may be limited to a certain range.

[0098] See also Figure 8 In some examples, the locking member 2123 may include an elastic segment 2123c. One end of the elastic segment 2123c may be connected between the movable end 2123a and the fulcrum end 2123b, and the other end of the elastic segment 2123c may be connected to the first bottom plate 2121. In this case, when a force is applied to the movable end 2123a toward or away from the fixing member 2122, the elastic segment 2123c may be deformed and may store elastic potential energy, and then when the force applied to the movable end 2123a is canceled, the elastic segment 2123c may release the stored elastic potential energy.

[0099] In some examples, the elastic section 2123c can be a spring.

[0100] In some examples, one end of the elastic section 2123c connected to the first bottom plate 2121 may be located on the side of the fulcrum end 2123b away from the fixing member 2122, and has a tendency to act toward the fixing member 2122. For example, when the elastic section 2123c is a spring, the spring may be in a compressed state, and at this time, the elastic section 2123c may have a tendency to act toward the fixing member 2122. Thus, the stability of the assembly of the bearing portion 211 and the main body portion 212 can be improved.

[0101] In some examples, one end of the elastic section 2123c connected to the first bottom plate 2121 may be located on the side of the fulcrum end 2123b close to the fixing member 2122, and has a tendency to act close to the fixing member 2122. For example, when the elastic section 2123c is a spring, the spring may be in a stretched state, and at this time, the elastic section 2123c may have a tendency to act close to the fixing member 2122. Thus, the stability of the assembly of the bearing portion 211 and the main body portion 212 can be improved.

[0102] In some examples, the locking member 2123 may include an extension 2123d (see Figure 7B). The central axis of the extension section 2123d may be at a preset angle to the line connecting the movable end 2123a and the fulcrum end 2123b. In this case, by applying an action to the extension section 2123d, the convenience of changing the locking member 2123 from the locked state to the unlocked state can be improved.

[0103] In some examples, the preset angle may be 30 degrees, 60 degrees, 90 degrees, 120 degrees, or the like.

[0104] In some examples, the extension section 2123d may have a through hole, so that other components can be easily coupled to the locking member 2123 through the through hole of the extension section 2123d.

[0105] In some examples, the main body 212 may further include a stopper 2124 (see Fig. 7A or Figure 7B The limiting member 2124 may be fixed to the first bottom plate 2121 .

[0106] In some examples, the stopper 2124 may include two side walls 2124a with a gap (see Fig. 7A or Figure 7B In some examples, the two side walls 2124a may be formed with a pass-through area. In some examples, when the carrying portion 211 is assembled with the main body 212, at least a portion of the carrying portion 211 may be in the pass-through area.

[0107] In some examples, the stopper 2124 may be coupled to the fixing member 2122 .

[0108] In some examples, the fixing member 2122 may sequentially penetrate the side walls 2124 a of the plurality of limiting members 2124 .

[0109] In some examples, the fixing member 2122 may be disposed in the limiting member 2124. In some examples, the limiting member 2124 may be disposed close to the locking member 2123. In this case, through the cooperation between the fixing member 2122, the locking member 2123 and the limiting member 2124, the deviation of the bearing portion 211 relative to the first bottom plate 2121 can be limited, which can help improve the consistency of the coating film.

[0110] In some examples, when the bearing portion 211 and the main body 212 are assembled, the locking member 2123 in the locked state can abut against the bearing portion 211, and when the locking member 2123 is acted on in a direction away from the fixing member 2122, the locking member 2123 can be changed from the locked state to the unlocked state. Thus, the convenience of disassembling the bearing portion 211 and the main body 212 can be improved.

[0111] In some examples, the fixing member 2122 may include a curved surface that contacts the bearing portion 211. In some examples, the locking member 2123 may include a curved surface that contacts the bearing portion 211.

[0112] See also Figure 3 In some examples, the bearing portion 211 may include a first recess 2114 that cooperates with the fixing member 2122. In some examples, the bearing portion 211 may include a second recess 2115 that cooperates with the locking member 2123.

[0113] In some examples, when the bearing portion 211 is assembled with the main body 212, the curved surface of the fixing member 2122 may abut against the first recess 2114. In some examples, when the bearing portion 211 is assembled with the main body 212, the curved surface of the locking member 2123 may abut against the second recess 2115. In this case, the stability of the fixing member 2122 and the locking member 2123 when they abut against the bearing portion 211 can be improved, thereby improving the stability of the bearing portion 211 and the main body 212 when they are assembled. Thus, the stably assembled bearing portion 211 and the main body 212 can prevent the sensor array 1 from being easily offset during coating, thereby improving the consistency of the coating.

[0114] In some examples, at one end of the bearing portion 211 close to the second recess 2115, the bearing portion 211 may have a guide surface 2116 adjacent to the second recess 2115. The guide surface 2116 may be configured to contact the curved surface of the locking member 2123 to guide the locking member 2123 to the unlocked state. Specifically, along the edge of the bottom of the substrate 2111, the guide surface 2116 may gradually transition to the second recess 2115. In this case, when the bearing portion 211 and the main body portion 212 are assembled, one end of the bearing portion 211 is first brought into contact with the fixing member 2122, and then the other end of the bearing portion 211 is pressed downward toward the main body portion 212. This allows a portion of the downward pressure on the bearing portion 211 toward the main body 212 to be transmitted to the locking member 2123 in a direction away from the fixing member 2122 through the guiding action of the guide surface 2116, thereby enabling the locking member 2123 to be changed from a locked state to an unlocked state without directly acting on the locking member 2123, thereby improving the convenience of assembling the bearing portion 211 and the main body 212.

[0115] In some examples, the carrying mechanism 21 may further include an applying portion. The applying portion may be used to control the assembly of the carrying portion 211 and the main body portion 212 .

[0116] In some examples, the application portion can be coupled with multiple locking members 2123 to batch operate multiple locking members 2123. In this case, it is convenient to batchly turn multiple locking members 2123 from a locked state to an unlocked state, so that multiple bearing portions 211 and the main body portion 212 can be assembled at one time, thereby further improving the efficiency of coating multiple sensors 10.

[0117] In some examples, the applying portion can be coupled with the extension segments 2123d of the plurality of locking members 2123 to batch operate the plurality of locking members 2123. In some examples, the applying portion can include a plurality of columnar structures, and the columnar structures of the applying portion can match the through holes of the extension segments 2123d to couple the applying portion with the plurality of locking members 2123.

[0118] In some examples, the applying portion may also be coupled to a plurality of the carrying portions 211 to operate the plurality of the carrying portions 211 in batches.

[0119] Fig. 9 Schematic diagram showing the structure of the liquid containing mechanism 22 involved in the example of the present disclosure.

[0120] In some examples, the coating device 2 may further include a liquid holding mechanism 22 (see Fig. 9 ). The liquid holding mechanism 22 may include a device for holding the coating liquid.

[0121] In some examples, the liquid holding mechanism 22 may include a second bottom plate 221 .

[0122] In some examples, the liquid holding mechanism 22 may include a plurality of liquid tanks 222 of the same shape. The liquid tanks 222 may be used to hold the coating liquid.

[0123] In some examples, the liquid groove 222 may be formed in the second bottom plate 221. In some examples, the second bottom plate 221 may be hollow at a location where the liquid groove 222 is not formed.

[0124] In some examples, the wall thickness of the plurality of liquid tanks 222 may be consistent. In this case, the inconsistent stress inside the second bottom plate 221 can be alleviated, thereby improving the flatness of the second bottom plate 221, thereby improving the consistency of the height of the coating liquid contained in the liquid tanks 222, and further improving the consistency of the coating.

[0125] In some examples, there may be a plurality of second bottom plates 221. For example, there may be two, three, four or more second bottom plates 221.

[0126] In some examples, the liquid holding mechanism 22 can move relative to the carrying mechanism 21 so that the to-be-coated portion 110 of each sensor 10 fixed to the carrying portion 221 is immersed in the coating liquid in the liquid tank 222. In some examples, the to-be-coated portion 110 of each sensor 10 fixed to the carrying portion 221 can leave the coating liquid in the liquid tank 222 to form a film layer on the to-be-coated portion 110 of each sensor 10.

[0127] Fig.10 2 is a cross-sectional view showing a liquid tank 222 according to an example of the present disclosure.

[0128] See also Fig.10 In some examples, the cross-section of the liquid tank 222 may be roughly “V” shaped.

[0129] In some examples, the liquid tank 222 may have a containing space 2221 (see Fig.10 ). The containing space 2221 may be truncated cone-shaped. In some examples, the cross-sectional area at the opening of the liquid tank 222 is larger than the cross-sectional area at the bottom. In this case, when the liquid tank 222 is filled, by injecting the coating liquid into the liquid tank 222 away from the center line of the containing space 2221, the coating liquid can flow into the bottom of the liquid tank 222 along the wall of the liquid tank 222 and gradually fill the opening of the liquid tank 222, thereby reducing the air remaining in the coating liquid in the liquid tank 222, thereby improving the quality of the coating.

[0130] In the present disclosure, a plurality of sensors 10 are connected in sequence to form a sensor array 1, and the upper surfaces of the respective sensors 10 are in the same plane, so that the surface of the sensor array 1 can be made flat, and when the sensor array 1 is fixed to a supporting mechanism 21, the portions to be coated 110 of the plurality of sensors 10 can be neatly arranged on the supporting mechanism 21, thereby when the portions to be coated 110 are immersed in a coating liquid in a liquid tank 222 of the same shape and leave for coating, the consistency of coating the plurality of sensors 10 at the same time can be improved.

[0131] In some examples, the coating device 2 of the present disclosure can be applied to a coating system. In some examples, the coating system can automatically perform some of the aforementioned operations (for example, changing the locking member 2123 from a locked state to an unlocked state) through a pre-set program. In some examples, the coating system can also include a liquid injection mechanism, which can supply liquid to the liquid holding mechanism 22.

[0132] Although the present disclosure is specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the above description does not limit the present disclosure in any form. Those skilled in the art may modify and change the present disclosure as needed without departing from the essential spirit and scope of the present disclosure, and these modifications and changes all fall within the scope of the present disclosure.
