Description

Technical Field

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

[0002] In recent years, with the development of science and technology, coating and curing devices, as a type of coating forming tool, are used to apply coating liquid to the fixture to be coated and perform coating liquid curing operation to obtain accurate coating structure in a convenient and quick manner. They are widely used in medical devices, power devices, chemical devices and other fields.

[0003] Currently, coating devices for long guidewire catheters mainly employ immersion coating methods, typically using storage tanks or tubes to hold the coating solution. However, the presence of storage tanks or tubes increases the space required for the coating device, hindering miniaturization design. Furthermore, the large contact area between the storage tank or tube and the external environment makes the coating solution highly volatile during the coating and curing process, increasing production costs. Moreover, as the immersion coating operation time and frequency increase, the coating solution in the storage tank or tube becomes contaminated. Failure to replace the coating solution in a timely manner will lead to a decline in product coating quality. Replacing the coating solution in the storage tank or tube is generally cumbersome and results in the waste of remaining coating solution, leading to resource waste and hindering production cost control. Summary of the Invention

[0004] Therefore, it is necessary to provide a coating module, coating device, and coating method to address the problems of large size, high production cost, and poor coating quality of existing coating and curing devices.

[0005] This invention provides a coating module that cooperates with a material hanging module having a component to be coated, comprising:

[0006] The first drive unit has at least one output terminal for providing a driving force for vertical movement;

[0007] At least one coating unit, the coating unit including a support member and a plurality of cup coating members, one end of the support member is installed at the output end of the first drive unit, and the other end extends into the underside of the fixture to be coated, the support member has a plurality of first slots extending vertically through, the cup coating members are detachably installed in the first slots and have a first through hole extending vertically through, the cup coating members and the fixture to be coated through the first through hole cooperate to form a liquid storage space for storing coating liquid.

[0008] In the aforementioned coating module, an appropriate amount of coating liquid is added to the storage space. The first drive unit is activated, and its output end drives the support member to move vertically relative to the hanging module. The bowl coating component moves with the support member relative to the object to be coated, so as to perform the coating operation on the object to be coated. Since each object to be coated corresponds to one bowl coating component, the structure of the bowl coating component is smaller than that of the existing storage tank or storage pipe, and occupies less space, which is conducive to the miniaturization of the coating module. The amount of coating liquid used for the object to be coated in the bowl coating component is small and controllable, and the contact area with the outside is small, so the evaporation is reduced, which can avoid resource waste and reduce production costs. Furthermore, when the coating liquid is contaminated, the bowl coating component can be removed from the first slot hole for replacement to ensure the cleanliness of the coating liquid and guarantee the coating quality.

[0009] In one embodiment, the first driving unit includes a plurality of first driving mechanisms, which are spaced apart along a first direction perpendicular to the vertical direction.

[0010] The number of coating units is multiple, and the multiple coating units are arranged sequentially along the vertical direction, with multiple bowl coating parts on two adjacent coating units facing each other in the vertical direction.

[0011] In one embodiment, each of the first drive mechanisms includes a first power source and a lead screw, the lead screw extending in a vertical direction and being drively connected to the first power source; a support member is threadedly connected to a lead screw.

[0012] In one embodiment, the support includes:

[0013] A connecting plate, one end of which is threaded to the lead screw, and the other end which extends under the component to be coated;

[0014] The support plate includes a first plate and a second plate. The first plate is connected to the connecting plate, and the second plate is connected to the first plate and is suspended relative to the connecting plate along a second direction. The second direction is perpendicular to the first direction and the vertical direction, respectively.

[0015] Multiple first slots are formed in the support plate, and the first slots are detachably connected to the bowl coating.

[0016] In one embodiment, the first slot opens on the side of the second plate away from the first plate, and the cross-sectional shape along the vertical direction is Z-shaped. The bowl coating component is a flexible bowl-shaped structure, which is sleeved and attached to the outside of the component to be coated. The outer surface of the bowl coating component has an annular groove, which engages with the first slot shown.

[0017] In one embodiment, the connecting plate has a wedge-shaped region on the side away from the lead screw in a cross-sectional shape perpendicular to the second direction, and two adjacent wedge-shaped regions in the vertical direction have the same slope and opposite inclination directions.

[0018] In addition, the present invention also provides a coating and curing apparatus, comprising:

[0019] The shell has an internal coating area, which includes an initial position and a feeding position.

[0020] At least one curing module is disposed within the housing, including a box with one end open and a light source disposed within the box;

[0021] The coating module described in any of the above technical solutions is disposed in the coating area, and the output end of the first driving unit is used to provide a driving force for reciprocating movement in the initial position and the feeding position in the vertical direction;

[0022] The material hanging module is located inside the housing, which isolates the box opening and the coating module. It cooperates with the box to form a curing area and is used to load and drive the firmware to be coated to rotate.

[0023] The control module is communicatively connected to the first drive unit.

[0024] In the aforementioned coating and curing device, the control module controls the operation of the first drive unit. The output end of the first drive unit drives the support member to move vertically to the initial position. At the initial position, the cup coating component can be directly installed, or the cup coating component can be replaced from the first slot if the coating liquid is contaminated, ensuring the cleanliness of the coating liquid and guaranteeing coating quality. Then, the cup coating component is fitted onto the fixture to be coated, which is installed on the material hanging module. The control module controls the operation of the first drive unit, and the output end of the first drive unit drives the coating module to the feeding position, adding an appropriate amount of coating liquid to the storage space. The output end of the device drives the support to move downwards in the vertical direction. The cup coating component moves downwards with the support to the object to be coated, so as to perform the coating operation on the object. After the coating is completed, the curing module performs the curing operation. Since each object to be coated corresponds to one cup coating component, the structure of the cup coating component is smaller in size than the existing liquid storage tank or liquid storage pipe, and occupies less space, which is conducive to the miniaturization of the coating and curing device. The amount of coating liquid used for the object to be coated in the cup coating component is small and controllable, and the contact area with the outside is small, so the evaporation is reduced, which can avoid resource waste and reduce production costs.

[0025] In one embodiment, the coating device further includes a second drive unit and at least one fixture. The second drive unit is communicatively connected to the control module, and its output is used to provide a driving force for reciprocating movement in the vertical direction between the initial position and the feeding position. The fixture is used to load the component to be coated, is located directly above the support member, and is mounted on the output of the second drive unit.

[0026] In one embodiment, the curing module further includes a shielding component, which includes a shielding door and a third drive unit. The third drive unit is communicatively connected to the control module, and its fixed end is mounted on the housing. Its output end provides a driving force for switching the shielding door between shielding and exposing the housing opening.

[0027] In one embodiment, the housing includes a switch door and a fourth drive unit. The housing has an operating port, the opening and closing state of which is opposite to that of the housing opening. The third drive unit is communicatively connected to the control module and its fixed end is mounted on the housing. Its output end provides a driving force for switching the switch door between blocking and revealing the operating port.

[0028] In one embodiment, the material hanging module further includes a support plate on which the fixture is mounted. The second drive unit includes a cylinder and a slide. The cylinder is communicatively connected to the control module, with its fixed end installed on the housing and its output end extending and retracting vertically. One end of the slide is installed on the output end of the cylinder, and the other end is connected to the support plate.

[0029] In addition, the present invention also provides a coating method for the coating device as described in any of the above technical solutions, comprising:

[0030] Step S901: Install or update the bowl coating part in the initial position, and the fixing part to be coated passes through the first through hole and is installed on the hanging module;

[0031] Step S902: The control module controls the first drive unit to move the cup coating part to the feeding position and add liquid in the liquid storage space formed by the cup coating part and the piece to be coated.

[0032] Step S903: The control module controls the first drive unit to move, causing the bowl-shaped part to descend to the set position;

[0033] Step S904: Set the time for the firmware to be coated after the light source irradiates it.

[0034] In the coating method of the above-mentioned coating device, firstly, in step S901, the control module controls the first drive unit to move. The output end of the first drive unit drives the support member to move vertically to the initial position. At the initial position, the cup coating member is updated, and then the cup coating member is placed on the fixture to be coated. The fixture to be coated is installed on the hanging module. Then, in step S902, the control module controls the first drive unit to move. The output end of the first drive unit drives the coating module to move to the feeding position and adds an appropriate amount of coating liquid to the liquid storage space. Next, in step S903, the control module controls the first drive unit to move. Its output end drives the support member to move vertically downward. The cup coating member moves downward with the support member relative to the fixture to be coated, so as to perform the coating operation on the fixture to be coated. Finally, in step S904, after the coating is completed, the light source irradiates the coated fixture to be coated for a set time to perform the curing operation. The coating method of the above-mentioned coating device is simple in logic and easy to implement, and can conveniently achieve low-cost and high-quality coating operation.

[0058] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0059] like Figure 1 , Figure 2 as well as Figure 3As shown, the present invention provides a coating module 300, which cooperates with a material hanging module 400 having a component 20 to be coated, as part of a coating and fixing device 10, for performing the coating operation on the component 20. The coating module 300 includes a first driving unit 310 and at least one coating unit 320, and the number of coating units 320 can be one, two, three, or more.

[0060] The first driving unit 310 has at least one output terminal, and the number of output terminals of the first driving unit 310 corresponds to the number of coating units 320. The output terminals of the first driving unit 310 are used to provide driving force for movement in the vertical direction Z.

[0061] The coating unit 320 includes a support member 321 and multiple cup coating members 322. The number of cup coating members 322 corresponds to the number of fixtures 20 to be coated on the material hanging module 400, and can be five, ten, or other numbers. Each cup coating member 322 corresponds to one fixture 20 to be coated. One end of the support member 321 is installed at the output end of the first drive unit 310, and the other end of the support member 321 extends below the fixture 20 to be coated. The support member 321 has multiple first slots 3211. The number of first slots 3211 corresponds to the number of fixtures 20 to be coated on the material hanging module 400. The first slots 3211 are through holes along the vertical direction Z. The cup coating component 322 is installed in the first slot 3211 and can be detached from the first slot 3211. The cup coating component 322 has a first through hole 3221, which is a through hole in the vertical direction Z. The cup coating component 322 and the die to be coated 20 passing through the first through hole 3221 cooperate to form a liquid storage space C, which is used to store the coating liquid 30.

[0062] In the coating module 300, an appropriate amount of coating liquid 30 is added to the liquid storage space C. The first drive unit 310 is activated, and its output end drives the support member 321 to move relative to the hanging module 400 in the vertical direction Z. The bowl coating member 322 moves relative to the object to be coated 20 with the support member 321 to perform the coating operation on the object to be coated 20. Since each object to be coated 20 corresponds to one bowl coating member 322, the structure of the bowl coating member 322 is smaller than that of the existing liquid storage tank or liquid storage pipe, and occupies less space, which is conducive to the miniaturization of the coating module 300. The amount of coating liquid 30 used for the coating operation of the object to be coated 20 in the bowl coating member 322 is small and controllable, and the contact area with the outside is small, so the evaporation is reduced, which can avoid resource waste and reduce production costs. Furthermore, when the coating liquid 30 is contaminated, the bowl coating member 322 can be removed from the first slot hole 3211 for replacement to ensure the cleanliness of the coating liquid 30 and ensure the coating quality.

[0063] The first driving unit 310 has various structural forms. In a preferred embodiment, such as... Figure 1, Figure 2 as well as Figure 3 As shown, the first driving unit 310 includes a plurality of first driving mechanisms 311, the number of which corresponds to the coating unit 320. The plurality of first driving mechanisms 311 are arranged at intervals along the first direction X, which is perpendicular to the vertical direction Z.

[0064] Multiple coating units 320 are provided to facilitate simultaneous coating operations on multiple sets of components 20 to be coated. These coating units 320 are arranged sequentially along the vertical direction Z, with multiple cup-shaped coating elements 322 on adjacent coating units 320 facing each other. Specifically, a straight line parallel to the vertical direction Z passes through multiple coating units 320 and multiple cup-shaped coating elements 322. The coating liquid used on the multiple cup-shaped coating elements 322 facing each other in different coating units 320 is different to complete multiple coating processes. The coating liquid used on the multiple cup-shaped coating elements 322 in the same coating unit 320 can be the same for batch coating operations, or different to accommodate situations where different coating layers exist in a batch of components 20 to be coated.

[0065] The first drive mechanism 311 has various structural forms. In a preferred embodiment, each first drive mechanism 311 includes a first power source 3111 and a lead screw 3112. The lead screw 3112 extends in the vertical direction Z and is connected to the first power source 3111 in a transmission manner. In a specific configuration, the first power source 3111 can be a servo motor, which is connected to the lead screw 3112 through a coupling, belt drive, gear drive, chain drive, etc. Of course, the structural form of the first power source 3111 is not limited to this and can also be other structural forms that meet the requirements. A support member 321 is threadedly connected to the lead screw 3112. In a specific configuration, the support member 321 and the lead screw 3112 are connected through a bushing. The bushing is externally connected to one side of the support member 321 and is sleeved on the lead screw 3112. Of course, the connection method between the support member 321 and the lead screw 3112 is not limited to this and can also be other structural forms that meet the requirements.

[0066] In the coating module 300 described above, the first power source 3111 is activated, and its output drives the lead screw 3112 to rotate around the vertical direction Z. The support member 321 moves along the vertical direction Z through its threaded engagement with the lead screw 3112. The forward and reverse movements of the first power source 3111 cause the support member 321 to move up and down along the vertical direction Z, thereby driving the coating unit 320 to reciprocate along the vertical direction Z. Furthermore, a first drive mechanism 311 drives a coating unit 320 to move, completing one coating process. Multiple coating bowls 322 are mounted on the same substrate 20 to be coated. Each coating bowl 322 moves to complete one coating operation. Multiple coating operations on multiple substrates 20 can be achieved through the separate driving of multiple drive mechanisms. In specific settings, in order to limit the travel of the coating unit 320, a position sensor or limit switch can be set at the starting position of the travel of the coating unit 320. Of course, the structure of the first drive unit 310 is not limited to this, and can be other required structures.

[0067] The support member 321 has various structural forms. In a preferred embodiment, such as... Figure 2 as well as Figure 3 As shown, the support member 321 includes a connecting plate 3212 and a support plate 3213. The connecting plate 3212 and the support plate 3213 are integrally formed. The connecting plate 3212 and the support plate 3213 can also be separately set and then combined together.

[0068] One end of the connecting plate 3212 is threaded to the lead screw 3112 via a bushing, and the other end of the connecting plate 3212 extends into the underside of the fixture 20 to be coated. In specific settings, in order to improve the stability of movement, a groove is formed at the end of the connecting plate 3212 facing the lead screw 3112. The first drive unit 310 is also provided with a slide rail 3113. Through the movable cooperation of the slide rail 3113 and the groove, the connecting plate 3212 can move stably in the vertical direction Z.

[0069] The support plate 3213 includes a first plate 3214 and a second plate 3215. The first plate 3214 is connected to the connecting plate 3212 by means of threaded connection, snap-fit ​​connection, or concave-convex fit. Alternatively, the first plate 3214 and the connecting plate 3212 are integrally formed, and the second plate 3215 is connected to the first plate 3214 by means of threaded connection, snap-fit ​​connection, or concave-convex fit. Alternatively, the second plate 3215 is integrally formed with the first plate 3214. The second plate 3215 is suspended relative to the connecting plate 3212 along the second direction Y. The second direction Y is perpendicular to the first direction X and the vertical direction Z, respectively.

[0070] A plurality of first slots 3211 are formed in the support plate 3213, and the first slots 3211 are detachably connected to the bowl coating member 322 as a whole; specifically, the plurality of first slots 3211 may be arranged at intervals on the support plate 3213. For example, the plurality of first slots 3211 are arranged at intervals along the first direction X. For another example, the plurality of first slots 3211 are arranged in an array on the support plate 3213.

[0071] In the above coating module 300, when the bowl coating member 322 needs to be replaced, the snap connection between the bowl coating member 322 and the first slots 3211 can be directly released, and the disassembly of the old bowl coating member 322 can be quickly achieved. By directly connecting the new bowl coating member 322 to the first slots 3211, the installation of the new bowl coating member 322 can be quickly achieved. By defining that the support member 321 includes a connecting plate 3212, a first plate body 3214 and a second plate body 3215, it is convenient and quick to replace any of the above structural members when damaged, reducing production costs. The second plate body 3215 is suspended relative to the connecting plate 3212 to form a misaligned space for the workpiece 20 to pass through. Specifically, the structural form of the support member 321 is not limited to this, and it can also be other forms that can meet the requirements, such as a cuboid structure.

[0072] To facilitate the installation of the bowl coating member 322, specifically, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the first slots 3211 open on the side of the second plate body 3215 away from the first plate body 3214, and the cross-sectional shape of the first slots 3211 perpendicular to the vertical direction Z is a "J" shape. The "J" shape means that the first slots 3211 are recessed inward along the second direction Y, and the edge area of the first slots 3211 away from the first plate body 3214 is in a smoothly tapered shape relative to the area close to the first plate body 3214. The bowl coating member 322 is in a bowl shape and is made of a flexible material, such as an elastic material such as silica gel or rubber. The bowl coating member 322 is sleeved outside the workpiece 20 to be coated, and the bowl coating member 322 is fitted with the workpiece 20 to be coated, so that the workpiece 20 to be coated can smoothly and easily penetrate the bottom of the bowl coating member 322. After the workpiece 20 to be coated passes through, there can be a certain sealing performance between the bowl coating member 322 and the workpiece 20 to be coated, and the coating liquid in the bowl coating member 322 will not flow out. Specifically, the size of the first through hole 3221 is slightly smaller than the outer diameter of the workpiece 20 to be coated. A card slot 3222 is formed on the outer surface of the bowl coating member 322. The card slot 3222 is arranged in a ring shape on the outer surface of the bowl coating member 322, and the card slot 3222 is in snap-fit with the first slots 3211 shown.

[0073] In the aforementioned coating module 300, during the assembly of the coating unit 320, the operator aligns the slot 3222 with the side of the first slot 3211 away from the first plate 3214, and then presses the slot 3222 into the first slot 3211. During the pressing process, the cup-coated part 322 is deformed by the groove wall of the first slot 3211, thus allowing it to smoothly enter the first slot 3211. After the operator releases the pressure, the cup-coated part 322 springs back, so that it can be stably locked in the corresponding first slot. Within the slot 3211; when assembling the liquid storage space C, the component to be coated 20 is inserted into the first through hole 3221, and the component to be coated 20 penetrates the first through hole 3221. The cup-shaped coating component 322 deforms under force to fit against the component to be coated 20, making the assembly process convenient and quick. At this time, the cup-shaped coating component 322 faces upward, and the cup-shaped coating component 322 and the component to be coated 20 form the liquid storage space C by fitting together with their outer walls. In order to facilitate the addition of coating liquid, the cup-shaped coating component 322 can be flared outward. In specific settings, the structural form of the first slot 3211 and the cup-shaped coating component 322 is not limited to this, and can also be other forms that meet the requirements.

[0074] Specifically, such as Figure 3 As shown, the connecting plate 3212 has a wedge-shaped region D on the side away from the lead screw 3112 in the cross-sectional shape perpendicular to the second direction Y, so that the connecting plate 3212 gradually widens as it approaches the first drive mechanism 311 along the first direction X, and the center of gravity of the connecting plate 3212 is close to the first drive mechanism 311. This allows the center of gravity of the overall support member 321 to be close to the lead screw 3112, thereby making the movement of the support member 321 more stable, ensuring uniform coating of the coating liquid 30, and guaranteeing the coating quality. The slopes of two adjacent wedge-shaped regions D along the vertical direction Z are the same, and the inclination directions of these two wedge-shaped regions D are opposite. For example, the hypotenuse of the upper wedge-shaped region D is located below, and the hypotenuse of the lower wedge-shaped region D is located above. This makes the distance between two adjacent wedge-shaped regions D smaller, thereby shortening the distance between two cup coaters 322 located on the same straight line parallel to the vertical direction Z in two adjacent coating units 320. This can shorten the misalignment distance between the two coating liquids 30 in the two cup coaters 322, ensure coating yield, reduce material waste, and lower production costs.

[0075] In addition, such as Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, the present invention also provides a coating and curing device 10, which can be used for the preparation of functional coatings for guidewires of medical consumables such as catheters, microcatheters, colonoscopy tubes, and gastric tubes. The coating and curing device 10 includes a housing 100, at least one curing module 200, a coating module 300 as described in any of the above technical solutions, and a material hanging module 400, wherein:

[0076] The housing 100 has a coating area A inside, which has an initial position and a feeding position. In a specific configuration, the housing 100 includes an outer shell 110 and a frame. The outer shell 110 covers the outside of the frame. The initial position is the position where the operator installs and updates the bowl coating part 322. The feeding position is the position where the operator adds the coating liquid 30. The initial position is located below the feeding position. For ease of explanation, the first direction X is the length direction of the frame 120, the second direction Y is the width direction of the frame 120, and the vertical direction Z is the height direction of the frame 120.

[0077] The curing module 200 is housed within the housing 100. The curing module 200 includes a housing 210 and a light source 220. The housing 210 has an open end, and the light source 220 is located inside the housing 210. In specific configurations, the number of curing modules 200 can be one, two, three, or more. Multiple curing modules 200 are arranged along a first direction X. The housing 210 is mounted on a support, with its opening facing the coating area A. The number of light sources 220 can be one, two, three, four, or more. Multiple light sources 220 can be arranged along a vertical direction Z, or they can be arrayed within the housing 210. Preferably, the light source 220 is positioned on the side wall of the housing 210 along a second direction Y opposite to its opening. The opening directions of the multiple curing modules 200 are consistent, but not necessarily... In addition to this, other forms that can meet the requirements can also be used; in addition, a reflector can be provided on the outside of the light source 220, with the opening of the reflector facing the opening of the housing 210. The light emitted by the light source 220 can be emitted through the opening of the reflector and the opening of the housing 210 to improve the utilization rate of the light. In order to make the light more uniform, a reflector can also be provided at the center of the light source 220 corresponding to the opening of the reflector, so that the stronger light source 220 emitted from the center of the light source 220 is reflected into the reflector for further reflection, thereby ensuring that the light source 220 illuminates the uncoated fastener 20 after the coating operation has been completed.

[0078] The coating module 300 is disposed in the coating area A. The fixed end of the first drive unit 310 is mounted on the frame 120. The output end of the first drive unit 310 is used to provide the driving force for reciprocating movement in the vertical direction Z between the initial position and the feeding position.

[0079] The material hanging module 400 is located inside the housing 100, and the material hanging module 400 isolates the opening of the box 210 and the coating module 300. The material hanging module 400 cooperates with the box 210 to define the specific area of ​​the curing zone B. The material hanging module 400 is used to load the fixture 20 to be coated, and the material hanging module is also used to drive the fixture 20 to be coated to rotate during curing.

[0080] The control module is communicatively connected to the first drive unit 310. In specific settings, the control module is communicatively connected to the first power source 3111, the position sensor, or the limit switch. To facilitate fixed operation, the control module can also be communicatively connected to the light source 220. The control module can be a control panel, which is embedded in the housing 110 for easy operation by the operator. The control panel contains a control program, and the operator can achieve human-machine interaction through the touch panel. Of course, the control module can also be other structural forms that meet the requirements.

[0081] In the aforementioned coating and curing device 10, the control module controls the first drive unit 310 to operate. The output end of the first drive unit 310 drives the support member 321 to move vertically in the Z direction to the initial position. At the initial position, the bowl coating member 322 can be directly installed, or the bowl coating member 322 can be replaced from the first slot 3211 if the coating liquid 30 is contaminated, to ensure the cleanliness of the coating liquid 30 and guarantee the coating quality. Then, the bowl coating member 322 is fitted onto the fixture 20 to be coated, which is installed on the material hanging module 400. The control module controls the first drive unit 310 to operate, and the output end of the first drive unit 310 drives the coating module 300 to move to the feeding position, adding an appropriate amount of coating liquid 30 to the liquid storage space C. When the drive unit 310 is activated, its output end drives the support member 321 to move downward in the vertical direction Z. The cup coating member 322 moves downward with the support member 321 relative to the object to be coated 20 to perform the coating operation on the object to be coated 20. After the coating is completed, the curing module 200 performs the curing operation. Since each object to be coated 20 corresponds to one cup coating member 322, the structure of the cup coating member 322 is smaller in size than the existing liquid storage tank or liquid storage pipe, and occupies less space, which is conducive to the miniaturization of the coating and curing device 10. The amount of coating liquid 30 used for the coating operation of the object to be coated 20 in the cup coating member 322 is small and controllable. The contact area with the outside is small, and the evaporation is reduced accordingly, which can avoid resource waste and reduce production costs.

[0082] The material loading module 400 has various structural forms. In a preferred embodiment, the material loading module 400 includes a second drive unit 410 and at least one fixture 420, the number of fixtures 420 corresponding to the number of curing modules 200. The second drive unit 410 is communicatively connected to the control module. The fixed end of the second drive unit 410 is mounted on the frame 120. The output end of the second drive unit 410 provides a driving force for reciprocating movement along the vertical direction Z between the initial position and the feeding position. The fixture 420 is used to load the components 20 to be coated. Multiple components can be loaded on one fixture 420. The fixture 420 is located directly above the support 321 and is mounted on the output end of the second drive unit 410. In specific configurations, by setting multiple fixtures 420 and multiple curing modules 200, the uniformity of the curing light and the curing efficiency can be increased, thereby improving the curing effect.

[0083] In the above-mentioned coating and curing device 10, the material hanging module 400 and the coating module 300 move in coordination to facilitate coating and curing operations. In the specific working process, the control module controls the first drive unit 310 and the second drive unit 410 to move. The output end of the first drive unit 310 drives the support member 321 and the output end of the second drive unit 410 drives the fixture 420 to move in the vertical direction Z to the initial position. Then, the bowl coating member 322 is sleeved on the fixture 20 to be coated. The fixture 20 to be coated is installed on the fixture 420. The control module controls the first drive unit 310 and the second drive unit 410 to move. The output end of the first drive unit 310 drives the coating module 300 and the output end of the second drive unit 410 to move the fixture 420 and the fixture 20 to be coated to the material feeding position.

[0084] To ensure precise curing, in a preferred embodiment, such as Figure 7 As shown, the curing module 200 also includes a shielding component 230, which includes a shielding door 231 and a third drive unit 232. The third drive unit 232 is communicatively connected to the control module, and its fixed end is mounted on the housing 210. The output end of the third drive unit 232 provides a driving force for switching the shielding door 231 between shielding and exposing the opening of the housing 210. In specific configurations, the third drive unit 232 can be a servo motor, and the shielding door 231 can be a double door. The orthographic projection size of the shielding door 231 on the housing 210 is larger than the opening size of the housing 210. The structural form of the shielding door 231 and the third drive unit 232 is not limited to these and can also be other structural forms that meet the requirements.

[0085] In the above-mentioned coating and curing device 10, when a curing operation is required, the control module controls the third drive unit 232 to move forward, and the output end of the third drive unit 232 rotates clockwise, causing the shielding door 231 to leave the opening of the box 210. After the opening of the box 210 is exposed, the control module controls the third drive unit 232 to stop moving, and the light source 220 performs the curing operation. After a set interval, the curing of the light source 220 stops, the control module determines that the curing operation is completed, and controls the third drive unit 232 to move in reverse, and the output end of the third drive unit 232 rotates counterclockwise, causing the shielding door 231 to move toward the opening of the box 210. After the opening of the box 210 is shielded, the control module controls the third drive unit 232 to stop moving, so as to accurately control the curing start time and curing duration, ensuring the accuracy of the curing operation. The structure is simple and the shielding process is easy to implement. In a specific configuration, the upper and lower ends of the shielding door 231 are rotatably connected to the upper and lower plates of the curing chamber via pivots. The pivots of the shielding door 231 pass through the upper plate and are connected to the corresponding third drive unit 232 located on the upper side of the upper plate. Of course, the driving method is not limited to this; for example, the third drive unit 232 can be located on the lower side of the lower plate; the pivot can be replaced with a hinge or other rotating connecting component connected to the inner wall of the curing chamber; or the top of the shielding door 231 passes through the upper plate of the curing chamber and is connected to the third drive unit 232 via a gear and rack.

[0086] To improve security, specifically, such as Figure 1 as well as Figure 6 As shown, the housing 100 includes a switch door 130 and a fourth drive unit 140. An operation port is provided on the housing 100. The operation port is specifically located on the side wall of the housing 110 away from the box 210 and directly opposite to the opening of the box 210. The opening and closing state of the operation port is opposite to that of the opening of the box 210. The third drive unit 232 is communicatively connected to the control module, and the fixed end of the third drive unit 232 is mounted on the housing 100. The output end of the third drive unit 232 provides a driving force for driving the switch door 130 to switch between blocking and revealing the operation port. In specific configurations, the fourth drive unit 140 can be a linear drive source, such as a cylinder 411, with the door 130 connected to the linear drive source via a gear and rack; the fourth drive unit 140 can also be a rotary drive source, such as a servo motor, with the door 130 connected to the rotary drive source via a shaft, hinge, etc.; the fourth drive unit 140 can also be an electromagnetic adsorption assembly, which is connected to the control module. When the light-shielding door is exposed above the opening of the housing 210, the electromagnetic adsorption assembly is in operation, and the door 130 is adsorbed at the operating opening, which not only blocks the operating opening but also ensures that the door 130 cannot be easily opened, further improving safety.

[0087] In the aforementioned coating device 10, when the shielding door 231 exposes the opening of the housing 210, the control module controls the fourth drive unit 140 to move in the forward direction. The output end of the fourth drive unit 140 drives the switch door 130 to close, and the switch door 130 blocks the operating opening to isolate the inside and outside of the housing 100, effectively preventing the light emitted by the light source 220 from shining out and causing harm to the operator's health. When the shielding door 231 blocks the opening of the housing 210, the control module controls the fourth drive unit 140 to move in the reverse direction. The output end of the fourth drive unit 140 drives the switch door 130 to open, exposing the operating opening to connect the inside and outside of the housing 100. At this time, the operator can safely perform operations such as assembling and disassembling the coating bowl 322, adding coating liquid 30, coating, and drying. In specific configuration, to accommodate the first drive mechanism 311 being located on one side of the material hanging module 400, the shielding component 230 includes multiple light-shielding plates 233. Two light-shielding plates 233 are arranged on both sides of the support member 321 along a third direction. One light-shielding plate 233 extends from the end of the support member 321 to the operating port, and the other light-shielding plate 233 extends from the end of the support member 321 to the opening of the housing 210. Light-shielding plates 233 are correspondingly arranged on both sides of the material hanging module 400. At this time, the opening and closing door 130, the light-shielding plates 233, and the housing 210 together form a new curing zone B, which includes the coating zone A. At this time, the light emitted by the light source 220 can be effectively utilized, improving the curing efficiency.

[0088] The hanging module 400 has various structural forms. In a preferred embodiment, such as... Figure 8 As shown, the material hanging module 400 also includes a support plate 430, which extends along the first direction X, and a fixture 420 is provided on the support plate 430. The second drive unit 410 includes a cylinder 411 and a slide 412. The cylinder 411 is communicatively connected to the control module. The fixed end of the cylinder 411 is mounted on the frame 120, and the output end of the cylinder 411 extends and retracts along the vertical direction Z. One end of the slide 412 is mounted on the output end of the cylinder 411, and the other end of the slide 412 is connected to the support plate 430 through a fixing member 440. Multiple fixtures 420 can be mounted on the support plate 430. The fixing member 440 and the second drive unit 410 are located in the middle area of ​​the support plate 430 to ensure the stability of the structure. In specific configurations, the structure of the second drive unit 410 is not limited to this; it can also be other structural forms that meet the requirements, such as screw rotation drive or slide rail 3113 drive.

[0089] In the above-mentioned coating and curing device 10, the control module controls the cylinder 411 to move forward, the output end of the cylinder 411 extends in the vertical direction Z, driving the slide table 412 to slide downward in the vertical direction Z. The slide table 412 drives the support plate 430 to move along with it through the fixing member 440, and the fixture 420 moves downward so that the fixture 420 moves to the initial position to perform the loading and unloading of the cup coating part 322. The control module controls the cylinder 411 to move in the reverse direction, the output end of the cylinder 411 retracts in the vertical direction Z, driving the slide table 412 to slide upward in the vertical direction Z. The slide table 412 drives the support plate 430 to move along with it through the fixing member 440, and the fixture 420 moves upward so that the fixture 420 moves to the feeding position to perform the feeding, coating, drying and curing operations. Therefore, the above-mentioned hanging module 400 can conveniently realize the coating and curing operation, and the structure is simple. In a specific configuration, the fixture 420 includes multiple carrier shafts 421, a gear transmission mechanism 422, and a second power source 423. The second power source 423 is a servo motor, which drives the gear transmission mechanism 422 to move. The carrier shafts 421 are rotatably mounted on the opening of the support plate 430 along the vertical direction Z via bearings and are installed on the gear shaft of the gear transmission mechanism 422 to support the fixture 20 to be coated. The multiple carrier shafts 421 are spaced apart along the first direction X. The number of groups of carrier shafts 421 on the support plate 430 corresponds to the curing module 200 and they are spaced apart. Of course, the driving method of the carrier shafts 421 is not limited to the gear transmission mechanism 422 and the second power source 423 mentioned above, and can also be other structural forms that can meet the requirements.

[0090] In addition, such as Figure 9 As shown, the present invention also provides a coating and curing method for the coating and curing apparatus 10 as described in any of the above technical solutions, comprising:

[0091] Step S901: Install or update the cup coating component 322 in the initial position, and the component to be coated 20 passes through the first through hole 3221 and is installed on the hanging module 400; In specific settings, the component to be coated 20 passes through the first through hole 3221 and is installed on the fixture 420. The switch door 130 is manually opened. At this time, the shielding door 231 is in the closed state, and the hanging mechanism and the support component 321 are in the initial position. The operator can hang the component to be coated 20 in this initial position. If there is no cup coating component 322 on the support component 321 at this time, the cup coating component 322 is manually installed into the first slot 3211 of the support component 321 in sequence. One end of the component 20 to be coated is sequentially passed through the cup coating component 322 on the support 321 and connected to the corresponding carrier shaft 421 on the fixture 420. If the support 321 has a cup coating component 322 at this time and it needs to be replaced at the feeding position, the output end of the first drive unit 310 drives all the support 321s and the output end of the second drive unit 410 drives the fixture 420 to move in the vertical direction Z to the initial position, and a new cup coating component 322 is replaced as needed. It should be noted that when the coating module 300 has multiple coating units 320, the component 20 to be coated needs to pass through the corresponding cup coating components 322 on multiple support 321s at once.

[0092] Step S902: The control module controls the first drive unit 310 to move the bowl coating component 322 to the feeding position and add liquid into the liquid storage space formed by the bowl coating component 322 and the component to be coated 20. In specific settings, the control module controls the first drive unit 310 and the second drive unit 410 to move the bowl coating component 322, the fixture 420, and the component to be coated 20 to the feeding position. The control module controls the hanging module 400 and all coating units 320 to rise synchronously to the feeding position. The coating liquid 30 is manually added to the bowl coating component 322 of all coating units 320. One type of coating liquid 30 can be set in the bowl coating component 322 of one coating unit 320. The coating liquid 30 in the bowl coating component 322 of multiple coating units 320 can be the same or different. Then, the switch door 130 is manually closed, and the coating unit 322 is lowered to the set position to coat the component to be coated 20.

[0093] Step S903: The control module controls the first drive unit 310 to move, driving the bowl coating part 322 down to the set position; in specific settings, when the control module receives that the switch door 130 is in the closed state, it opens the shielding door 231, and the light source 220 cures the coated part 20.

[0094] Step S904: The light source 220 irradiates the coated component 20 for a set time. In specific settings, the second power source 423 drives the gear transmission mechanism 422 to move. The gear shaft of the gear transmission mechanism 422 drives the component 20 to rotate, improving curing efficiency and curing uniformity. After curing, the shielding door 231 closes, and the switch door 130 is opened manually. If multiple coatings are required, the first coating liquid 30 is added to the bottom bowl coating component 322. After the first curing operation is completed, the coating liquid 30 is added to the bowl coating component 322 of the second to last coating unit 320. The switch door 130 is closed manually, and the second coating unit 320 descends to the set position to perform a second coating on the component 20 that has completed the first curing. After the second curing operation is completed, the above process is repeated until all coating and curing operations are completed. Then, the switch door 130 is opened manually and the component is removed.

[0095] In the coating method of the above-mentioned coating device 10, firstly, through step S901, the control module controls the first drive unit 310 to operate. The output end of the first drive unit 310 drives the support member 321 to move vertically in the Z direction to the initial position. At the initial position, the cup coating member 322 is updated. Then, the cup coating member 322 is fitted onto the fixture 20 to be coated, and the fixture 20 to be coated is installed on the material hanging module 400. Then, through step S902, the control module controls the first drive unit 310 to operate. The output end of the first drive unit 310 drives the coating module 300 to move to the feeding position and coats the liquid storage space C. Add an appropriate amount of coating liquid 30; then, through step S903, the control module controls the first drive unit 310 to operate, and its output end drives the support member 321 to move downward in the vertical direction Z. The cup coating member 322 moves downward with the support member 321 relative to the object to be coated 20, so as to perform the coating operation on the object to be coated 20; finally, through step S904, after the coating is completed, the light source 220 irradiates the coated object to be coated 20 for a set time to perform the curing operation; the coating curing method of the above coating curing device 10 has a simple logic and is easy to implement, and can conveniently achieve low-cost and high-quality coating curing operation.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
