Description

Technical Field

[0001] The present invention relates to the field of coating technology, and in particular to a coating module, a coating device and a coating method thereof. Background Art

[0002] With the development of science and technology in recent years, the coating device, as a coating forming tool, is used to apply the coating liquid on the object to be coated and perform the coating liquid curing operation to obtain the precise coating structure conveniently and quickly. It is widely used in medical equipment, power equipment, chemical equipment and other industries.

[0003] At present, the coating operation of the coating device for long guide wire catheter mainly includes the following two types: 1. Adopting the immersion coating method, using a liquid storage tank or a liquid storage tube to hold the coating liquid, but the existence of the liquid storage tank or the liquid storage tube will increase the space of the coating device to a certain extent, which is not conducive to miniaturization design, and as the time and number of immersion coating operations increase, the coating liquid will be contaminated. If the coating liquid is not replaced in time, the coating quality of the product will be reduced. The replacement of the coating liquid is generally cumbersome and will cause waste of the remaining coating liquid, resulting in waste of resources, which is not conducive to controlling production costs. 2. Adopting the bowl coating method, using a bowl coating piece to hold the coating liquid, but one bowl coating piece corresponds to one long guide wire catheter, and the coating liquid needs to be added to each bowl coating piece. The operation is cumbersome, and the coating liquid in the bowl coating piece cannot be recycled, resulting in waste of the remaining coating liquid, which will also cause waste of resources and is not conducive to controlling production costs.

[0004] Therefore, providing a coating module, a coating device and a coating method with good coating quality and high coating liquid utilization rate is a technical problem that needs to be solved urgently. Summary of the invention

[0005] Based on this, it is necessary to provide a coating module, a coating device and a coating method thereof to address the above technical problems.

[0071] The technical solution provided by the embodiments of the present invention is described below in conjunction with the accompanying drawings.

[0072] like Figure 1 , Figure 2 As shown, the present invention provides a coating device 10 , which is used to apply a coating liquid 30 to a workpiece 20 to be coated.

[0073] For reference Figure 3 As shown, the present invention provides a coating module 300, which is suitable for use in a coating device 10. The coating module 300 is used in conjunction with a hanging module 400. In a specific setting, the coating module 300 is arranged below the hanging module 400 loaded with the fixed body 20 to be coated, and as a part of the coating device 10, is used to realize the coating operation on the fixed body 20 to be coated.

[0074] like Figure 3 as well as Figure 4As shown, the coating module 300 includes at least one coating cup 310 and a driving module 320. The number of coating cups 310 can be one, two, three or more than three. The coating cup 310 includes a first cup body 311, at least two second cup bodies 312 and at least two penetration holes 313. The number of the second cup body 312 and the penetration holes 313 is equal, and both can be one, two, three or more than three. In each coating cup 310, the second cup body 312 is sealed and connected to the bottom wall of the first cup body 311. The penetration hole 313 penetrates the first cup body 311 and the second cup body 312 along the vertical direction Z, and the height of the top of the penetration hole 313 in the vertical direction Z is less than the height of the top of the first cup body 311 in the vertical direction Z, so that the coating liquid 30 inside the first cup body 311 can flow into the inside of the penetration hole 313. The through hole 313 is used to accommodate the fixture 20 to be coated. The size of the through hole 313 is slightly larger than the fixture 20 to be coated, so that the fixture 20 to be coated can slide in the through hole 313 and ensure that the coating liquid 30 does not flow directly from the gap between the second cup body 312 and the fixture 20 to be coated.

[0075] The coating cup 310 has various structural forms. In a preferred embodiment, Figure 3 as well as Figure 4 As shown, the bottom wall of the first cup body 311 has at least two bearing areas 3111, and the bearing area 3111 is provided with a first through hole 3112 along the vertical direction Z; the second cup body 312 is fixed in the first through hole 3112 of the bearing area 3111 to achieve the connection between the second cup body 312 and the first cup body 311. The second cup body 312 is provided with a second through hole 3121 along the vertical direction Z, and the opening areas of the second through hole 3121 and the first through hole 3112 are both larger than the cross-sectional area of ​​the fixed body 20 to be coated, and the second through hole 3121 and the first through hole 3112 cooperate to form a through hole 313. In the specific setting, the opening areas of the second through hole 3121 and the first through hole 3112 are slightly larger than the cross-sectional area of ​​the fixed body 20 to be coated to prevent the coating liquid 30 from flowing directly down.

[0076] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, in one example, at least two bearing areas 3111 protrude from the inner side of the bottom wall of the first cup body 311 and are located inside the first cup body 311. At this time, the bearing area 3111 includes a portion of the bottom wall of the first cup body 311 and a protrusion located on the inner side of this portion of the bottom wall. After the second cup body 312 is connected to the bottom wall of the first cup body 311 as a whole, the top of the second cup body 312 is located inside the first cup body 311 to ensure that the height of the top of the penetration hole 313 in the vertical direction Z is less than the height of the top of the first cup body 311 in the vertical direction Z. Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, in another example, at least two bearing areas 3111 protrude from the outside of the bottom wall of the first cup body 311 and are located outside the first cup body 311. In this case, the bearing area 3111 includes a portion of the bottom wall of the first cup body 311 and a protrusion located on the outside of the portion of the bottom wall. Of course, the structural form of the bearing area 3111 is not limited to this. The bearing area 3111 can also be a portion of the bottom wall of the first cup body 311, and the first through hole 3112 is directly opened on the bottom wall of the first cup body 311 where the bearing area 3111 is located.

[0077] In order to expand the application scenarios of the coating cup 310, in a preferred embodiment, the second cup body 312 and the first cup body 311 are connected as a whole, and the second cup body 312 can be removed relative to the bottom wall of the first cup body 311. At this time, only the second cup body 312 needs to be replaced to be suitable for different hardware 20 to be coated.

[0078] In one example, the second cup body 312 is a stepped structure having a large end and a small end, with the large end facing upward and the small end facing downward to cooperate with the first through hole 3112, and the small end is arranged in the first through hole 3112 by means of threaded locking, magnetic plug, concave-convex matching, snap connection, etc. to achieve a simple and reliable detachable connection between the second cup body 312 and the first cup body 311.

[0079] In one example, after the second cup body 312 and the first cup body 311 are locked together, the small end thereof exceeds the bottom surface of the first cup body 311, and the second through hole 3121 constitutes the material penetration hole 313. In another example, after the second cup body 312 and the first cup body 311 are locked together, the small end thereof does not exceed the bottom surface of the first cup body 311, and the second through hole 3121 and the first through hole 3112 cooperate to constitute the material penetration hole 313.

[0080] To improve the reliability of the coating cup 310, in one example, Figure 3 , Figure 5 , Figure 8 as well as Fig. 9 As shown, the coating cup 310 further includes a first seal 330, which is disposed between the surfaces of the second cup body 312 and the bearing area 3111 that are opposite to each other in the vertical direction Z, so as to seal the gap between the second cup body 312 and the bearing area 3111 through the first seal 330. In specific configuration, the first seal 330 can be directly disposed between the second cup body 312 and the bearing area 3111, or can be disposed in a groove of either the second cup body 312 or the bearing area 3111, and the first seal 330 can be a sealing strip, a sealing ring, or a sealing gasket.

[0081] like Figure 4 , Figure 6, Figure 7 as well as Fig.10 As shown, in another example, the coating cup 310 further includes a second sealing member 340, which is sleeved on the outer side of the second cup body 312, and one end of the second sealing member 340 is provided with a third through hole 341 for the coating member 20 to pass through, and the other end of the second sealing member 340 is attached to the bearing area 3111, so that the gap between the second cup body 312 and the bearing area 3111 is sealed by the second sealing member 340, and when the second cup body 312 is removed from the second cup body 312, the second sealing member 340 and the second cup body 312 can be directly removed together. In a specific setting, the second sealing member 340 can be a sealing sleeve.

[0082] Whether it is the first seal 330 or the second seal 340, on the one hand, it can prevent the coating liquid 30 from directly seeping out from between the second cup body 312 and the first cup body 311, so that more coating liquid 30 can be applied, thereby improving the utilization rate of the coating liquid 30. On the other hand, it can also prevent the coating liquid 30 from remaining between the second cup body 312 and the first cup body 311 and affecting the disassembly of the second cup body 312, thereby facilitating the subsequent replacement of the second cup body 312.

[0083] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, the output end of the driving module 320 reciprocates along the vertical direction Z, the output end of the driving module 320 is connected to the first cup body 311 as a whole, and the first cup body 311 can be detached relative to the output end of the driving module 320. In a specific setting, the connection between the output end of the driving module 320 and the first cup body 311 can be any one or a combination of threaded connection, concave-convex fit, snap connection, magnetic attraction, etc.

[0084] The drive module 320 has various structural forms. In a preferred embodiment, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10As shown, the driving module 320 includes a power source 321 and a support plate 322, wherein: the power source 321 has an extended end for providing a driving force for moving along the vertical direction Z. In specific settings, the power source 321 can be a cylinder, a hydraulic cylinder, a motor + screw, etc., or other structural forms that can meet the requirements; the support plate 322 is connected to the extended end of the power source 321 by threaded connection, concave-convex matching, snap connection, etc., and at least one bearing hole 3221 is opened on the support plate 322, and the bearing hole 3221 passes through the support plate 322 along the vertical direction Z, and the number of the bearing holes 3221 is adapted to the first cup body 311, and the bearing holes 3221 are embedded and matched with the first cup body 311. During operation, the power source 321 moves, and its extended end drives the support plate 322 to move up and down along the vertical direction Z, and the coating cup 310 moves up or down accordingly.

[0085] In one example, specifically, Fig.11 As shown, the support plate 322 has a first direction X and a second direction Y, the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other, the number of the coating cups 310 and the bearing holes 3221 are at least two, at least two coating cups 310 are arranged at intervals along the first direction X, the number of the second cup bodies 312 and the penetration holes 313 are at least two, and at least two second cup bodies 312 are arranged at intervals along the second direction Y, so as to realize the coating operation of at least two array-distributed objects 20 to be coated. In the specific setting, the number of coating cups 310 is designed according to the arrangement of the to-be-coated fixtures 20 on the hanging module 400, N rows of fixtures 20 to be coated correspond to N coating cups 310 and N infusion pipelines 360, and the N coating cups 310 are arranged at a certain distance along the first direction X; the number of second cup bodies 312 and penetration holes 313 is designed according to the number of fixtures 20 to be coated in each row, each row of M fixtures 20 to be coated corresponds to M second cup bodies 312 and M penetration holes 313, and the M second cup bodies 312 are arranged at a set distance along the second direction Y.

[0086] like Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, the coating module 300 may only include at least one coating cup 310 and a driving module 320. In this case, the coating liquid 30 may be added manually by a pipette or by manual addition. Figure 5 , Figure 6 , Fig. 9 as well as Fig.10 As shown, the coating module 300 can also realize automatic addition of the coating liquid 30 . In a preferred embodiment, the coating module 300 further includes at least one infusion pipeline 360 ​​, and the number of the infusion pipeline 360 ​​is equal to that of the coating cups 310 .

[0087] One end of the infusion pipeline 360 ​​is connected to the first cup body 311, and the other end is connected to an external storage unit. The storage unit is used to store the coating liquid 30, and the infusion pipeline 360 ​​is used to provide a driving force for the coating liquid 30 to be transported from the storage unit to the first cup body 311. When the coating liquid 30 needs to be added, the infusion pipeline 360 ​​transports the coating liquid 30 from the storage unit to the first cup body 311 until the liquid level of the coating liquid 30 exceeds the top of the second cup body 312. After the coating is completed, the infusion pipeline 360 ​​transports the coating liquid 30 from the first cup body 311 to the storage unit. The uncoated coating liquid 30 can be recycled to avoid waste of the coating liquid 30 and facilitate control of production costs.

[0088] In a specific configuration, the liquid storage tank 350 may be a structure with an open top, and in order to reduce waste of the coating liquid 30 , specifically, an openable protective cover is provided at the top of the liquid storage tank 350 .

[0089] Specifically, the storage unit is a liquid reservoir 350, the upper opening of which is arranged directly below the coating cup 310, and the liquid reservoir 350 is used to store the coating liquid 30 and receive the coating liquid 30 flowing down from the fixed body 20 to be coated; during the coating operation, the excess coating liquid 30 will fall into the liquid reservoir 350 along the fixed body 20 to be coated through the material penetration hole 313, so as to avoid the waste of the coating liquid 30. At this time, the liquid reservoir 350 can be integrated into the coating module 300, and as a part of the coating module 300, it is applicable to the coating device 10. Of course, the storage unit is not limited to the above-mentioned liquid reservoir 350, and can also be other structural forms that can meet the requirements, such as a liquid storage tank, which exists independently of the coating module 300.

[0090] In order to facilitate the flow of the coating liquid 30, specifically, as Figure 5 , Figure 6 , Fig. 9 as well as Fig.10 As shown, the infusion pipeline 360 ​​includes a plunger pump 361, which is used to provide a driving force for the coating liquid 30 to flow between the liquid storage tank 350 and the first cup body 311. Since the plunger pump 361 has functions such as fine adjustment and liquid level detection, the plunger pump 361 can achieve precise delivery of the coating liquid 30 with a controllable flow rate, which is convenient for realizing automatic control of the coating liquid 30. In specific settings, the plunger pump 361 can be connected to the control module for communication, and the plunger pump 361 can also be independently controlled.

[0091] In order to facilitate the flow of the coating liquid 30, more specifically, as Figure 5 , Figure 6 , Fig. 9 as well as Fig.10As shown, at least one liquid outlet nozzle 351 is provided on the side wall of the liquid storage tank 350, and a liquid inlet nozzle 3113 is provided on the bottom wall of the first cup body 311 along the vertical direction Z. In a specific configuration, the liquid outlet nozzle 351 protrudes from the outer surface of the side wall of the liquid storage tank 350, and the liquid inlet nozzle 3113 protrudes from the outer surface of the bottom wall of the first cup body 311. The infusion pipeline 360 ​​also includes a liquid pipe 362, a plunger pump 361 is provided on the liquid pipe 362, one end of the liquid pipe 362 is connected to the liquid outlet nozzle 351, and the other end of the liquid pipe 362 is connected to the liquid inlet nozzle 3113. The flow direction of the coating liquid 30 is the liquid reservoir 350-liquid outlet 351-liquid pipe 362-plunger pump 361-liquid pipe 362-liquid inlet 3113-first cup body 311, or the flow direction of the coating liquid 30 is the first cup body 311-liquid inlet 3113-liquid pipe 362-plunger pump 361-liquid pipe 362-liquid outlet 351-liquid reservoir 350. Of course, the connection mode of the infusion pipeline 360, the liquid reservoir 350 and the first cup body 311 is not limited to this, and can also be other forms that can meet the requirements.

[0092] In order to expand the application scenarios of the coating module 300, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, in a preferred embodiment, the coating module 300 also includes a lifting seat 370, and the fixed ends of the liquid storage tank 350 and the driving module 320 are installed on the lifting seat 370 by means of threaded connection, snap connection, concave-convex matching, magnetic attraction, etc. The lifting seat 370 is configured to provide a driving force to move the fixed ends of the liquid storage tank 350 and the driving module 320 along the vertical direction Z. The height of the fixed ends of the liquid storage tank 350 and the driving module 320 can be adjusted by the lifting seat 370 to adjust the distance between the coating module 300 and the hanging module 400, so as to avoid the coating liquid 30 from splashing when falling, and adapt to the different lengths of the to-be-coated fixtures 20, so that the coating module 300 has strong adaptability and a wide range of uses. In the specific setting, the lifting seat 370 can be a cylinder + support plate, a motor + gear mechanism + support plate, and the lifting seat 370 can also be other structural forms that can meet the requirements. Of course, the lifting of the liquid storage tank 350 is not limited to the above-mentioned lifting seat 370, and can also be other ways that can meet the requirements. Furthermore, when the liquid storage tank 350 is not provided, the lifting seat 370 is only used to provide a driving force for the fixed end of the driving module 320 to move along the vertical direction Z.

[0093] When the coating module 300 is working, the to-be-coated fixture 20 carried by the hanging module 400 is inserted into the first cup body 311 and passes through the through hole 313. After a proper amount of coating liquid 30 is added into the first cup body 311, the coating liquid 30 enters into at least two second cup bodies 312. The output end of the driving module 320 drives the first cup body 311 to move upward or downward, and the second cup body 312 moves relative to the to-be-coated fixture 20 with the first cup body 311, so as to perform coating operation on the to-be-coated fixture 20. It is only necessary to remove the second cup body 312 from the bottom wall of the first cup body 311 and replace the second cup body 312 to adapt to fixtures 20 of different specifications and models to be coated. It has strong adaptability, a wide range of applications, and is convenient for subsequent promotion. One coating cup 310 corresponds to at least two to-be-coated fixtures 20. It is only necessary to add the coating liquid 30 once into the first cup body 311, which is simple to operate. Moreover, since the first cup body 311 is used as a communicating vessel, at least two second The liquid levels at the two cup bodies 312 are kept consistent, so that the amount of liquid added in the first cup body 311 can be more accurately controlled and the added coating liquid 30 is less, the contact area with the outside world is smaller, and the volatilization amount is reduced accordingly, thereby avoiding waste of the coating liquid 30. At the same time, at least two second cup bodies 312 can realize the simultaneous coating of at least two to-be-coated fixtures 20, which can realize large-scale mass production. The coating areas of at least two to-be-coated fixtures 20 are precisely consistent, so that the yield of the coated product is high; when the coating liquid 30 is contaminated, the coating cup 310 can be removed from the output end of the driving module 320, cleaned or replaced, and then new coating liquid 30 is added to ensure the cleanliness of the coating liquid 30 and the coating quality; and because the coating cup 310 moves up and down for coating operation, the existing liquid storage tank 350 or liquid storage tube 362 can be removed or the size can be adaptively changed, and the space occupied is small, which is conducive to the miniaturization of the coating module 300.

[0094] In addition, if Figure 1 , Figure 2 as well as Figure 3 As shown, the present invention also provides a coating device 10, which can be used for the functional coating preparation of guide wires of medical consumables such as catheters, microcatheters, colonoscope tubes, and gastric tubes. The coating device 10 includes a housing 100, at least one curing module 200, a coating module 300 such as any of the above technical solutions, a hanging module 400, and a control module, wherein:

[0095] A coating area is formed inside the shell 100, and the coating area has an initial position and a adding position. In the specific setting, the shell 100 includes a frame and an outer shell 110 mounted on the outside of the frame. The initial position is the position where the operator installs and updates the cup body of the coating liquid 30, and the adding position is the position for adding the coating liquid 30 into the first cup body 311. The initial position is located below the adding position.

[0096] The curing module 200 is arranged in the housing 100, and includes a box 210 and a light source 220; the box 210 has an open end, and the light source 220 is arranged inside the box 210. In the specific setting, the number of the curing modules 200 can be one or at least two, the box 210 is installed on the bracket, the opening of the box 210 faces the coating area, the light source 220 can be a UV mercury lamp, the number of the light sources 220 can be one or at least two, and the at least two light sources 220 can be arranged along the vertical direction Z, or can be distributed in an array in the box 210.

[0097] The coating module 300 is disposed in the coating area, and the driving module 320 of the coating module 300 is used to provide a driving force for reciprocating along the vertical direction Z between the initial position and the feeding position.

[0098] The material hanging module 400 is arranged in the housing 100, and the material hanging module 400 is located between the opening of the box 210 and the coating module 300. The material hanging module 400 cooperates with the box 210 to define a specific area of ​​the curing zone, and the curing zone is located above the coating zone. The curing zone and the coating zone can be separated to avoid the light source 220 of the curing module 200 from affecting the operator. Of course, the curing zone and the coating zone can be connected, and directly move to the curing zone for curing operation after the coating operation is completed. The material hanging module 400 is used to load the firmware 20 to be coated, and the material hanging module 400 is used to drive the firmware 20 to be coated to rotate during curing. Of course, the material hanging module 400 can also drive the firmware 20 to be coated away from the light source 220 when the curing operation is not required. For example, the material hanging module 400 drives the firmware 20 to be coated away from the light source 220 in the up and down direction, and out of the range of illumination of the curing zone, so as to reduce the damage of the light source 220 to the firmware 20 to be coated.

[0099] The control module is communicatively connected with the driving module 320; in a specific setting, the control module is communicatively connected with the power source 321. In order to facilitate the control of the curing operation, the control module can also be communicatively connected with the light source 220 and the hanging module 400. The control module can be a control panel embedded in the outer shell 110 for easy operation.

[0100] When the above-mentioned coating device 10 is working, the control module controls the driving module 320 to move, and the output end of the driving module 320 drives the coating cup 310 to move to the initial position along the vertical direction Z. The coating cup 310 can be directly installed at the initial position, or the coating cup 310 can be removed from the output end of the driving module 320 for replacement when the coating liquid 30 is contaminated. The to-be-coated fixture 20 carried by the hanging module 400 is inserted into the first cup body 311 and passes through the penetration hole 313. The output end of the driving module 320 drives the coating cup 310 to move to the feeding position along the vertical direction Z. After adding appropriate coating liquid 30 into the first cup body 311, the coating liquid 30 enters at least two second cup bodies 312. The driving module The output end of the block 320 drives the first cup body 311 to move upward or downward, and the second cup body 312 moves with the first cup body 311 relative to the firmware 20 to be coated, so as to perform a coating operation on the firmware 20 to be coated; the output end of the driving module 320 drives the first cup body 311 to move upward or downward, and the second cup body 312 moves with the first cup body 311 relative to the firmware 20 to be coated, so as to perform a coating operation on the firmware 20 to be coated; after the coating is completed, the curing operation is performed through the curing module 200. The coating device with the above-mentioned coating module 300 has good coating quality, high utilization rate of the coating liquid 30, low production cost, can be widely applied to firmware 20 to be coated with different specifications, and can achieve large-scale mass production.

[0101] For reference Fig.12 In addition, the present invention also provides a coating method of the coating device 10 according to the above technical solution, comprising:

[0102] Step S100, installing or updating the coating cup 310; in specific settings, the coating cup 310 can be directly installed on the output end of the driving module 320, or the entire coating cup 310 on the output end of the driving module 320 can be replaced, or the second cup body 312 on the output end of the driving module 320 can be replaced.

[0103] Step S200, the to-be-coated firmware 20 passes through the penetration hole 313 and is installed on the hanging module 400; in the specific setting, if the coating cup 310 is not in the initial position, the control module can control the driving module 320 to move to the initial position, and then the to-be-coated firmware 20 passes through the penetration hole 313 and is installed on the fixture 410 of the hanging module 400.

[0104] Step S300, the control module controls the driving module 320 to move, driving the coating cup 310 to move to the feeding position for feeding, and the coating liquid 30 enters the second cup body 312; in the specific setting, the addition of the coating liquid 30 needs to at least reach the liquid level of the coating liquid 30 exceeding the top of the second cup body 312, so as to facilitate the subsequent coating operation; the movement of the coating cup 310 precedes the addition of liquid to the coating cup 310, so as to avoid splashing of the coating liquid 30 and improve the utilization rate of the coating liquid 30.

[0105] Step S400, the control module controls the driving module 320 to move, driving the coating cup 310 to move upward or downward to a set position; in a specific setting, the output end of the driving module 320 drives the coating cup 310 to descend from the feeding position, and a layer of coating liquid 30 is formed on the to-be-coated component 20 until the coating cup 310 descends to the set position, and the coating of the to-be-coated component 20 is completed.

[0106] Step S500 , the light source 220 irradiates the coated hardware 20 for a set time. In a specific setting, the hanging module 400 drives the hardware 20 to be coated to rotate, so as to achieve a curing operation more quickly and evenly.

[0107] In the coating method of the coating device 10, first, through step S100, the control module controls the driving module 320 to move, and the output end of the driving module 320 drives the coating cup 310 to move along the vertical direction Z to the initial position, and the coating cup 310 can be directly installed or updated at the initial position, and then through step S200, the to-be-coated fixture 20 is inserted into the first cup body 311 and passed through the penetration hole 313, and the to-be-coated fixture 20 is installed on the hanging module 400; then through step S300, the control module controls the driving module 320 to move, and the output end of the driving module 320 drives the coating cup 310 to move along the vertical direction Z to the feeding position, and the to-be-coated fixture 20 is added in the first cup body 311. After the appropriate coating liquid 30 is added, the coating liquid 30 enters at least two second cup bodies 312; then through step S400, the control module controls the driving module 320 to operate, and the output end of the driving module 320 drives the first cup body 311 to move upward or downward, and the second cup body 312 moves with the first cup body 311 relative to the to-be-coated fixture 20 to perform a coating operation on the to-be-coated fixture 20; finally, through step S500, after the coating is completed, the light source 220 irradiates the coated fixture 20 for a set time to perform a curing operation; the coating method of the above-mentioned coating device 10 is simple in logic and easy to implement, and can more conveniently achieve low-cost, high-quality coating operations.
