Description

Technical Field

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

[0002] Currently, most existing coating equipment is manually operated, and multi-sided coating, such as double-sided coating, is achieved through dedicated coating stations. Taking inverter product technology as an example, the transistors inside inverter products generate a lot of heat during use, requiring the addition of heat-dissipating ceramic pads. To improve heat transfer, silicone grease needs to be applied between the transistors and the ceramic pads to enhance transistor heat dissipation and further extend the lifespan of the photovoltaic inverter. However, most existing coating equipment used for coating ceramic pads cannot achieve multi-sided coating, and manual coating cannot guarantee coating quality and efficiency. Utility Model Content

[0003] The main objective of this application is to propose a coating device that aims to solve the problem of the inability to achieve multi-faceted coating.

[0004] To achieve the above objectives, this application provides a coating device comprising:

[0006] A product flipping component is provided on the conveying component and is used to flip the product to be processed on the fixture according to the coating surface of the product to be processed.

[0007] Multiple coating components are disposed on the conveying component, and the multiple coating components respectively coat different coating surfaces of the product to be processed before and after the flipping process.

[0008] In one embodiment, there are multiple product flipping components, and the product flipping components are arranged between two adjacent coating components along the conveying direction of the conveying components.

[0009] In one embodiment, the product to be processed has a first coating surface and a second coating surface disposed opposite to each other, and the plurality of coating components include a first coating component and a second coating component;

[0010] Along the conveying direction of the conveying assembly, the product flipping assembly is disposed between the first coating assembly and the second coating assembly.

[0011] The first coating surface is positioned facing the first coating component; the second coating surface is positioned facing the second coating component.

[0012] In one embodiment, the product flipping assembly includes a moving mechanism and a flipping gripper, wherein the moving mechanism drives the flipping gripper to move closer to or away from the conveying assembly;

[0013] The flipping gripper flips the product to be processed so that the top-facing coating surface of the product is flipped from the first coating surface facing upwards to the second coating surface facing upwards.

[0014] In one embodiment, the fixture has multiple slots for accommodating products to be processed; the flipping gripper has a clamping position for clamping a product to be processed.

[0015] The flipping gripper has multiple gripping positions, and the positions of the multiple gripping positions correspond one-to-one with the multiple slots.

[0016] In one embodiment, the coating assembly includes a coating mechanism and a stencil assembly, the stencil assembly being engaged with a fixture on the conveying assembly, the stencil assembly having a plurality of meshes abutting against the product to be processed, the positions of the plurality of meshes corresponding to the positions of the plurality of slots;

[0017] The coating mechanism includes a scraper and a material outlet for discharging material to the scraper. The scraper is positioned toward the grid and coats the product to be processed that is in contact with the grid.

[0018] In one embodiment, along the conveying direction of the conveying assembly, the conveying assembly has a conveying start end and a conveying end end, and the product flipping assembly and a plurality of coating assemblies are disposed between the conveying start end and the conveying end end.

[0019] The coating device further includes a feeding assembly, which is located near the conveying start end. The feeding assembly includes a feeding section and a hopper, which is used to carry the product to be processed. The feeding section moves the hopper upward toward the conveying start end, or moves the hopper downward away from the conveying start end.

[0020] In one embodiment, the coating device further includes a suction cup assembly disposed close to the feeding assembly. The suction cup assembly includes a longitudinal moving part, a transverse moving part, and a suction cup part, the suction cup part being used to pick up or release the product to be processed.

[0021] The longitudinal moving part is connected to the suction cup part and drives the suction cup part to move upward away from the hopper or move downward towards the hopper; the lateral moving part is connected to the longitudinal moving part and drives the suction cup part to move laterally towards the hopper or move laterally towards the conveying component.

[0022] In one embodiment, the conveying component is a ring conveyor belt.

There are multiple coating components, which are set on the conveying component to coat different coating surfaces of the product to be processed before and after the flipping process, thereby realizing multi-face coating. This can effectively reduce the requirements for coating components, simplify the coating control process, and the overall structure is simple and easy to implement.

[0026] Multiple coating components installed on the conveying assembly enable coating treatment of multiple surfaces of the product to be processed. While coating one surface of the product on one fixture, coating other surfaces of the product on other fixtures can be coated simultaneously, achieving time reuse. This not only effectively improves coating efficiency, saves production costs, and ensures coating uniformity and consistency, but also improves coating quality and further enhances product quality and safety. It meets the coating requirements of different surfaces of the product to be processed and expands the application range of the coating device. Attached Figure Description

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0049] Currently, most existing coating equipment stations are manually operated, and multi-sided coating, such as double-sided coating, is achieved by setting up dedicated coating stations. However, manual coating cannot guarantee coating quality and efficiency.

[0050] Taking inverter product technology as an example, the transistors inside inverter products generate a lot of heat during use, requiring the addition of heat-dissipating ceramic pads. To improve heat transfer, silicone grease needs to be applied between the transistors and the ceramic pads to enhance transistor heat dissipation and further extend the lifespan of the photovoltaic inverter. However, most existing coating devices used for ceramic pads cannot achieve multi-sided coating, and manual coating cannot guarantee coating quality and efficiency, which not only compromises product quality but also affects the inverter's heat dissipation performance, increasing the risk of inverter damage.

[0051] To address the limitation of related technologies in achieving multi-faceted coating, refer to... Figures 1 to 8This application proposes a coating apparatus for achieving multi-sided coating, simplifying the structure of the coating apparatus, and improving overall processing efficiency through structural simplification. The coating apparatus includes a conveying assembly 100, a product flipping assembly 200 disposed along the conveying assembly 100, and a plurality of coating assemblies 300. Specifically, the product flipping assembly 200 can be disposed between two adjacent coating assemblies 300.

[0052] The product to be processed 800 has two, three, or other multiple coating surfaces, and the multiple coating surfaces of the product to be processed are specifically defined as a first coating surface, a second coating surface, etc. Optionally, taking ceramic gasket coating as an example, when the product to be processed includes a first coating surface and a second coating surface arranged opposite to each other, one of the first coating surface and the second coating surface arranged opposite to each other is the front side of the ceramic gasket and the other is the back side of the ceramic gasket.

[0053] The conveying assembly 100 refers to a series of equipment and mechanical structures used in the production and processing process to convey items such as products 800 (e.g., ceramic gaskets) and jigs 600 to be processed. Specifically, it includes, but is not limited to, a conveyor belt, a drive device to provide power for the operation of the conveyor belt, and detection components (such as sensors) for detecting the products 800 and jigs 600 being transported on the conveyor belt. The conveying assembly 100 has corresponding workstations for the product flipping assembly 200, coating assembly 300, etc.

[0054] The product flipping assembly 200 is mounted on the conveying assembly 100. The product flipping assembly 200 refers to a mechanical structure used in the production process to flip the product 800 (such as a ceramic gasket) and other items to be processed. It is mainly used on the production line to replace manual labor in flipping the product through automation, thereby improving production efficiency and reducing reliance on manual labor and reducing labor intensity. The product flipping assembly 200 specifically includes, but is not limited to, a flipping part (such as a flipping gripper 220) and a drive device for providing power for the rotation of the flipping part.

[0055] The coating assembly 300 is mounted on the conveying assembly 100. The coating assembly 300 refers to the equipment or tool used in the production process to coat the coating surface of the product 800 (such as a ceramic gasket) with a specific material. These materials include, but are not limited to, thermally conductive silicone grease, sealant, and protective coating, used to enhance product performance or protect its surface. The coating assembly 300 includes, but is not limited to, a coating mechanism and a stencil assembly 700. The coating mechanism includes, but is not limited to, a scraper 310, a material outlet for outputting material to the scraper 310, a screw valve 330 for extracting material from a container and outputting it to the material outlet, a pump, etc., and a bracket for supporting the scraper 310, etc. The stencil assembly 700 is used to limit the movement of the product 800, fixture 600, etc. on the conveying assembly 100. The stencil assembly 700 includes, but is not limited to, a mesh 711, etc.

[0056] Specifically, in the embodiments of this application, the conveying component 100 is used to convey the fixture 600, which is used to carry multiple products 800 to be processed. Optionally, the fixture 600 is provided with multiple slots 610, and the products 800 to be processed are accommodated through the slots 610. The conveying component 100 can be, but is not limited to, a conveyor belt. The conveying component 100 may optionally have one or more conveying sections, and depending on the actual workstation and application environment, different conveying sections may be configured with one or more directions. Multiple conveying sections may be optionally set separately or connected into a ring structure or any other structure suitable for actual use, which is not limited here.

[0057] To simplify the structure, reduce space occupation, improve the flexibility of workstation setup, and achieve continuous transmission, refer to Figure 2 In one embodiment, the conveying component 100 is a ring conveyor belt. Using a ring conveyor belt reduces the accumulation and waiting time of the jig 600 during transport, improves processing efficiency and coating quality, and prevents the jig 600 or other materials from falling during transport, effectively improving operational safety. Furthermore, its simple structure ensures the stability and reliability of equipment operation.

[0058] The product flipping assembly 200 is used to flip the product 800 on the fixture 600 according to the coating surface of the product 800 to be processed. There are two, three, or more coating assemblies 300, specifically defined as a first coating assembly 301, a second coating assembly 302, etc. Multiple coating assemblies respectively coat different coating surfaces of the product 800 before and after the flipping process, achieving multi-faceted coating. This effectively reduces the requirements for coating assemblies, simplifies the coating control process, and has a simple overall structure, making it easy to implement.

[0059] This application includes multiple coating components 300, each of which has a screw valve 330 for extruding coating material. The structure and coating material of each coating component 300 may be the same or different. Along the conveying direction of the conveying component 100, a product flipping component 200 is located between two adjacent coating components 300. The jig 600 is conveyed by the conveying component 100. When the jig 600 moves to the station corresponding to one of the coating components 300, one coating surface of the product 800 to be processed is coated by the corresponding coating component 300. Then the jig 600 moves to the station corresponding to the product flipping component 200. After the product flipping component 200 completes the flipping process of the product 800 to be processed, the jig 600 moves to the station corresponding to the next coating component 300, and the next coating component 300 completes the coating of the other coating surface of the product 800 to be processed after flipping.

[0060] Reference Figure 5Specifically, in addition to the aforementioned scraper 310 and material outlet for discharging material to the scraper 310, the coating assembly 300 also includes a coating lifting assembly 320, which drives the scraper 310 to move up and down between the rising position and the falling position. The position of the scraper 310 furthest from the conveying component 100 along the Z-axis is defined as the rising position, and the position of the scraper 310 closest to the conveying component 100 along the Z-axis is defined as the falling position. The scraper 310 can reciprocate. When the coating lifting component 320 drives the scraper 310 to rise, and the scraper 310 is in the rising position, the scraper 310 is set away from the conveying component 100, and the coating component 300 stops working in a standby state or other non-working state. Specifically, the scraper 310 stops reciprocating. When the coating lifting component 320 drives the scraper 310 to fall, and the scraper 310 is in the falling position, the scraper 310 contacts the product 800 to be processed, and can then coat the product 800 on the fixture 600. Specifically, the scraper 310 is used to coat the product 800 on the fixture 600 that has moved to the lower position during reciprocating motion.

[0061] This application primarily uses a coating device for coating ceramic gaskets in inverter manufacturing processes as an example. While related technologies also employ coating devices specifically designed to coat ceramic gaskets awaiting processing (products 800), most can only provide one coating assembly 300 to coat one side. Furthermore, the other side can only be coated after the ceramic gasket has been flipped over. Only one product 800 on a fixture 600 can be processed at a time, requiring the fixture 600 to remain at the corresponding station for an extended period, resulting in long waiting times and low production efficiency. Compared to other coating devices in related technologies that achieve multi-sided coating using only one coating component 300, the coating device of this application achieves coating on multiple different coating surfaces of the product 800 to be processed using multiple coating components 300. By setting up multiple coating components 300, the product 800 to be processed on different fixtures 600 can be processed. While processing one coating surface (such as the first coating surface) of the product 800 to be processed on one fixture 600, other coating surfaces (such as the second coating surface) of the product 800 to be processed on other fixtures 600 can be processed simultaneously, achieving time reuse and effectively improving processing efficiency. Since the silicone grease and other materials applied by different coating components 300 can be different, it can also be adapted to different application scenarios and meet the different heat dissipation performance requirements or other performance requirements of the ceramic gasket product 800 to be processed, effectively expanding the application range of the coating device. This setup can also effectively improve coating efficiency, save production costs, ensure uniformity and consistency of coating, improve coating quality, and meet the coating requirements of 800 different coating surfaces of the products to be processed.

[0062] Along the conveying direction of the conveying assembly 100, the conveying assembly 100 has a conveying start end and a conveying end end, and the product flipping assembly 200 and a plurality of coating assemblies 300 are disposed between the conveying start end and the conveying end end.

[0063] As an example, there are multiple product flipping assemblies 200, and a product flipping assembly 200 is provided between two adjacent coating assemblies 300 along the conveying direction of the conveying assembly 100. The product flipping assemblies 200 and the multiple coating assemblies 300 are spaced apart along the conveying direction (e.g., the X-axis) of the conveying assembly 100.

[0064] Specifically, along the X-axis (or Y-axis), multiple coating components 300 and multiple product flipping components 200 are sequentially arranged on the conveying component 100 with a product flipping component 200 between adjacent two coating components 300, so as to process products 800 with two, three or more other coating surfaces. The jig 600 is conveyed by the conveying component 100. When the jig 600 moves to the station corresponding to one of the coating components 300, the coating component 300 applies coating to the upward-facing surface of the product 800 to be processed. Then, the jig 600 moves to the station corresponding to the product flipping component 200, which flips the product 800 on the jig so that the upward-facing coating surface of the product 800 is flipped to the other side facing up. After that, the jig 600 moves to the station corresponding to the next coating component 300, which applies coating to the other side of the flipped product 800. This process is repeated until all coating surfaces of the product 800 are coated. The number of coating components 300 can be set according to the number of coating surfaces of the product 800 to be processed; the structure, coating material, number of coatings, etc. of different coating components 300, and the structure of different product flipping components 200, can be the same or different, and are not limited here.

[0065] The conveyor assembly 100 can be used to convey multiple fixtures 600 simultaneously, allowing different processes to be carried out synchronously or separately.

[0066] As another example, the product flipping assembly 200 includes one or more coating assemblies 300, including a first coating assembly 301 and a second coating assembly 302. The product flipping assembly 200 is positioned between the first coating assembly 301 and the second coating assembly 302 along the conveying direction of the conveying assembly 100. The first coating assembly 301, the product flipping assembly 200, the second coating assembly 302, etc., are spaced apart along the conveying direction (e.g., the X-axis) of the conveying assembly 100.

[0067] Specifically, a first coating component 301, a product flipping component 200, and a second coating component 302 are sequentially arranged on the conveying component 100 along the X-axis (or Y-axis) to process a product 800 having a first coating surface and a second coating surface. Specifically, the product to be processed 800 has a first coating surface and a second coating surface arranged opposite to each other. The jig 600 is conveyed by the conveying component 100. When the jig 600 moves to the station corresponding to the first coating component 301, the first coating component 301 applies coating to the upward-facing first coating surface of the product to be processed 800. Then, the jig 600 moves to the station corresponding to the product flipping component 200. The product flipping component 200 flips the product to be processed 800 on the jig, so that the upward-facing coating surface of the product to be processed 800 changes from the first coating surface facing upward to the second coating surface facing upward. After that, the jig 600 moves to the station corresponding to the second coating component 302, with the second coating surface facing the second coating component 302. The second coating component 302 then applies coating to the upward-facing second coating surface of the product to be processed 800 after it has been flipped.

[0068] The following embodiments of this application mainly illustrate that the product flipping assembly 200 has one or more coating assemblies 300, including a first coating assembly 301 and a second coating assembly 302. Along the conveying direction of the conveying assembly 100, the product flipping assembly 200 is disposed between the first coating assembly 301 and the second coating assembly 302. The specific example is the processing of ceramic gasket coating. If there are multiple product flipping assemblies 200, and along the conveying direction of the conveying assembly 100, a product flipping assembly 200 is disposed between two adjacent coating assemblies 300, and is used to process other products 800 with multiple coating surfaces, the specific implementation can be referred to accordingly, and will not be repeated.

[0069] In a ceramic gasket, one of the first and second coating surfaces, positioned opposite each other, is the front side of the ceramic gasket, and the other is the back side. One of the first coating assembly 301 and the second coating assembly 302 is used to coat the front side of the ceramic gasket, and the other is used to coat the back side. The structure, lifting position, coating material, and number of coats of the first coating assembly 301 and the second coating assembly 302 may be the same or different, and are not limited here.

[0070] Reference Figure 5 In one embodiment, in addition to the aforementioned coating mechanism, the coating assembly 300 also includes a stencil assembly 700, the position of which corresponds to the position of the coating mechanism, and the stencil assembly 700 engages with the fixture 600 on the conveying assembly 100 (or the stencil assembly 700 covers the fixture 600 on the conveying assembly 100).

[0071] Understandably, the range of motion of the stencil assembly 700 is determined by a first position and a second position. The first position is determined by the position of the stencil assembly 700 when it is closest to the conveying assembly, and the second position is determined by the position of the stencil assembly 700 when it is closest to the coating assembly 300. When the stencil assembly 700 moves to the first position, it moves closer to the conveying assembly 100 and engages (or covers) the fixture 600 on the conveying assembly 100. Specifically, the fixture 600 is used to engage (or cover) the fixture 600 on the conveying assembly 100 that is being conveyed to the corresponding station of the coating assembly 300. When the stencil assembly 700 moves to the second position, it moves closer to the coating assembly 300, which drives the engaged fixture 600 to move closer to the coating assembly 300. The scraper 310 is in a descending position and contacts the stencil assembly 700. Through the reciprocating motion of the scraper 310, the product 800 to be processed on the fixture 600 engaged by the stencil assembly 700 is coated.

[0072] The first and second positions can optionally be located in the same or different directions. The stencil assembly 700 located in the second position limits the jig 600 that is being conveyed to the bottom of the coating assembly 300 (or moved to another position near the coating assembly 300), and moves the limiting jig 600 to a position near the coating assembly 300 to achieve coating treatment of the product 800 to be processed on the jig 600. Specifically, the stencil assembly 700 can move and switch between the first and second positions along the vertical direction (Z-axis), and the stencil assembly 700 can be moved to rise to the first position or move down to the second position. The specific positions of the first and second positions can be set according to actual conditions and are not limited here.

[0073] Optionally, in this embodiment, the stencil assembly 700 includes, but is not limited to, a stencil 710, which is disposed between the scraper 310 and the conveying assembly 100. The stencil assembly 700 has a plurality of meshes 711 that abut against the product to be processed 800, and the positions of the plurality of meshes 711 correspond to the positions of a plurality of slots in the fixture 600; the scraper 310 of the coating mechanism is positioned toward the meshes 711 and coats the product to be processed that abuts the meshes.

[0074] The positions of multiple grids 711 in the middle of the steel mesh 710 correspond to the slots 610 of the fixture 600. The number of grids 711 in the steel mesh 710 and the number of slots 610 in the fixture 600 may be the same or different. The steel mesh 710 is used to press the product 800 to be processed on the fixture 600 through the grids 711, so as to prevent the product 800 to be processed from shifting position when the scraper 310 of the coating component 300 is scraping, thus affecting the processing quality.

[0075] The steel mesh assembly 700 also includes a steel mesh lifting assembly, which is used to move the steel mesh 710 between a first position and a second position. The steel mesh lifting assembly includes a steel mesh compaction assembly 720 and a compaction cylinder 730. The steel mesh 710 is disposed on the steel mesh compaction assembly 720. The compaction cylinder 730 drives the steel mesh compaction assembly 720 to move the steel mesh 710 between the first position and the second position, specifically by moving the steel mesh 710 up and down, thus enabling the steel mesh 710 to move between the first position and the second position.

[0076] Reference Figure 3 , Figure 4 In one embodiment, the product flipping assembly 200 includes a moving mechanism 210 and a flipping gripper 220. The moving mechanism 210 drives the flipping gripper 220 to move closer to or further away from the conveying assembly 100. The flipping gripper 220 flips the gripped product 800 to be processed, so that the top-facing coating surface of the product to be processed is flipped from a first coating surface facing upwards to a second coating surface facing upwards.

[0077] Optionally, the moving mechanism 210 is specifically, but not limited to, an XYZ three-axis motion mechanism. An XYZ three-axis motion mechanism refers to a mechanical structure capable of precise movement and positioning along the three coordinate directions of the X, Y, and Z axes in three-dimensional space. This mechanism typically consists of three mutually perpendicular linear motion axes, which can work independently or collaboratively to achieve precise positioning and manipulation of objects in three-dimensional space. Using the XYZ three-axis motion mechanism as the moving mechanism 210 drives the flipping gripper 220 to move closer to or away from the conveying assembly 100, so that the flipping gripper 220 can further flip the product 800 to be processed on the fixture 600 that has moved from the conveying assembly 100 to the workstation where the product flipping assembly 200 is located.

[0078] The moving mechanism 210 drives the flipping gripper 220 to move, which can be achieved in any one or more of the following ways: First, the moving mechanism 210 drives the flipping gripper 220 to move up or down along the Z-axis, so as to move the flipping gripper 220 to move up or down. The moving mechanism 210 drives the flipping gripper to move up so that the flipping gripper 220 moves away from the conveying component 100; the moving mechanism 210 drives the flipping gripper 220 to move down so that the flipping gripper 220 moves closer to the conveying component 100. When the flipping gripper 220 moves closer to the conveying component 100, it flips the entire fixture 600 that has moved to the corresponding station of the product flipping component 200, so that all the products 800 to be processed on the fixture are flipped from the first coating surface facing up to the second coating surface facing up, so that the subsequent coating component 300 (such as the second coating component 302) can coat the products 800 to be processed with the second coating surface facing up on the fixture 600. Secondly, the moving mechanism 210 drives the flipping gripper 220 to move up and down along the Z-axis, left and right along the X-axis, and / or forward and backward along the Y-axis. This is used to move the flipping gripper 220 up or down, and to move the flipping gripper 220 horizontally, so that the flipping gripper 220 moves closer to or away from the conveying component 100. When the flipping gripper 220 moves closer to the conveying component 100, it flips the product 800 to be processed on the fixture 600 at the corresponding station of the product flipping component 200.

[0079] After all surfaces of the product to be processed 800 have been coated, the product to be processed 800 is moved by the conveying component 100 to achieve unloading.

[0080] Optionally, the fixture 600 includes a fixture base plate 620 and a plurality of slots 610 disposed on the fixture base plate 620. Each slot 610 is used to accommodate a product 800 to be processed. The plurality of slots 610 of the fixture 600 can be arranged in multiple rows and / or multiple columns, and the plurality of slots 610 are arranged in a matrix. The specific arrangement can be determined according to actual conditions and is not limited here.

[0081] Reference Figure 3 , Figure 4 In one embodiment, the flipping gripper 220 has a clamping position 2201, which is used to clamp a product 800 to be processed.

[0082] Reference Figure 4Since the flipping gripper 220 can be opened and closed, the clamping position 2201 can be set at the end of the flipping gripper 220. Specifically, one, two or more clamping positions 2201 can be set in the closed position of the flipping gripper 220 to ensure that the flipping gripper 220 can stably clamp the product 800 to be processed. The flipping gripper 220 is closed (or opened) by the moving mechanism 210, etc., to realize the clamping (or release) of the product 800 to be processed.

[0083] Optionally, the moving mechanism 210 includes a shifting cylinder 211, a lifting cylinder 212, and a rotating cylinder 213. The rotating cylinder 213 is connected to the flipping gripper 220. The rotating cylinder 213 drives the flipping gripper 220 to rotate, so as to flip the coating surface of the product to be processed 800 upward from the first coating surface to the second coating surface. The lifting cylinder 212 drives the flipping gripper 220 to move up or down along the Z-axis. The shifting cylinder 211 drives the flipping gripper 220 to move along the Y-axis. Specifically, the lifting cylinder 212 drives the flipping gripper 220 to move and descend along the Z-axis, so that the flipping gripper 220 moves closer to the fixture 600 on the conveying assembly 100. After the flipping gripper 220 clamps the product 800 to be processed at the corresponding position, the shifting cylinder 211 drives the flipping gripper 220 to move along the Y-axis, so that the flipping gripper 220 moves away from the fixture 600. The rotating cylinder 213 drives the flipping gripper 220 to rotate, so as to flip the coating surface of the product 800 to be processed from the first coating surface facing upward to the second coating surface facing upward. After the flipping process is completed, the shifting cylinder 211 drives the flipping gripper 220 to move along the Y-axis, so that the flipping gripper 220 moves closer to the fixture 600, and the flipping gripper 220 releases the product 800 to be processed at the corresponding position.

[0084] The shifting cylinder 211, lifting cylinder 212, and rotating cylinder 213 can be supplied with air from a common air source or independent air sources, and operate independently through their respective automatic control systems. The shifting cylinder 211, lifting cylinder 212, and rotating cylinder 213 achieve precise control of the flipping gripper 220 or the entire product flipping assembly 200 through connection points (such as sliders, guide rails, etc.) with the flipping gripper 220. They also work collaboratively through their respective start-up controls and mechanical structure designs to complete the motion control of the flipping gripper 220. Specifically, the shifting cylinder 211 and lifting cylinder 212 can be connected through the first mounting plate 230, or further limited in their operation by the guide rails on the first mounting plate 230; this is not further specified here.

[0085] Reference Figure 7In one embodiment, the coating apparatus further includes a feeding assembly 500, which refers to a mechanical and control system for automatically or semi-automatically conveying ceramic gaskets awaiting processing from a storage area such as a hopper to a conveying assembly 100 or other processing area. The feeding assembly 500 is located near the beginning of the conveying process. Specifically, the feeding assembly 500 includes a feeding section 510 and a hopper 520, the hopper 520 being used to hold the products 800 to be processed; the feeding section 510 moves the hopper 520 upward toward the beginning of the conveying process, or the feeding section 510 moves the hopper 520 downward away from the beginning of the conveying process.

[0086] Optionally, before operation, ceramic pads of the appropriate specifications and quantities are placed in the hopper 520 by manual picking or machine packaging. When the multiple slots of the fixture 600 are arranged in a matrix, the fixture 600 is configured to have multiple columns arranged along the X-axis and multiple rows arranged along the Y-axis. The hopper 520 is provided with multiple material troughs 521 arranged along the Y-axis, each material trough 521 carrying multiple products 800 to be processed arranged along the Z-axis. The feeding unit 510 is used to pneumatically or electrically move the hopper 520 upward or downward along the Z-axis. When moving the hopper 520 upward, the hopper 520 is brought closer to the beginning of the conveying process to facilitate the transfer of the products 800 to be processed on the top layer to the slots on the fixture 600 at the beginning of the conveying process. When moving the hopper 520 downward, the hopper 520 is moved away from the end of the conveying process to facilitate feeding by manual picking or machine packaging.

[0087] Optionally, the feeding unit 510 includes, but is not limited to, a lifting module 511, a bearing 512, and a guide rod 513. The guide rod 513 is connected to the hopper 520, and the bearing 512 is connected to the guide rod 513 through a second mounting plate 540, etc. The lifting module 511 drives the guide rod 513 to move the hopper 520 up (or down). The feeding assembly 500 is equipped with a position detection component 530, such as a laser position sensor. The position detection component 530 is used to detect the position of the top product 800 to be processed in the hopper 520 (or to detect the position of other picking devices such as the suction cup assembly 400) and output a detection signal. The feeding assembly 500 also includes a control circuit electrically connected to the feeding unit 510 and the position detection component 530 respectively. The control circuit includes, but is not limited to, a PLC (Programmable Logic Controller), other types of controllers or other control devices. The control circuit is used to control the feeding unit 510 to work according to the detection signal transmitted by the position detection component 530, so as to control the feeding unit 510 to drive the hopper 520 to rise. It is used to drive the hopper 520 to rise to a preset height when the top product 800 to be processed in the hopper 520 is not in the preset highest position (or the suction cup assembly 400 or other picking devices move above the hopper), so as to ensure that the top ceramic gasket product 800 to be processed is always in the highest position of the hopper 520. The preset height of the material hopper 520 can be set to any size suitable for the actual setting, such as the thickness of the product to be processed 800 (e.g., ceramic gasket), and is not limited here.

[0088] Reference Figure 2 , Figure 6 In one embodiment, the coating device further includes a suction cup assembly 400, which refers to a device that uses vacuum adsorption to fix and transport ceramic pads awaiting processing. The suction cup assembly 400 is disposed near the feeding assembly 500 and includes a longitudinal moving part 411, a transverse moving part 412, and a suction cup part 420. The suction cup part 420 is used to pick up or release the product to be processed. The longitudinal moving part 411 is connected to the suction cup part 420 and drives the suction cup part 420 to move upward away from the hopper 520 or to move downward towards the hopper 520. The transverse moving part 412 is connected to the longitudinal moving part 411 and drives the suction cup part 420 to move laterally towards the hopper 520 or to move laterally towards the conveying assembly 100.

[0089] The suction cup assembly 400 picks up the product 800 to be processed from the hopper 520, etc., and transfers the picked-up product 800 to the fixture 600 placed at the beginning of the conveyor. Optionally, the suction cup 420 refers to a device that can use vacuum suction cup technology to generate negative pressure and transport ceramic pads. Compared with other feeding methods, picking up the product 800 to be processed by the suction cup assembly 400 can ensure that the ceramic pad waiting to be processed product 800 is placed flat on the corresponding slot 610 of the fixture 600, and ensure the integrity of the surface of the product 800 to be processed, avoiding damage to the surface of the product 800 to be processed, and can also improve work efficiency.

[0090] Reference Figure 6 The longitudinal moving part 411 is fixed on the base or support of the worktable and is responsible for linear motion along the Z-axis. The base or support of the worktable is provided with a guide rail 413 extending along the Z-axis. The longitudinal moving part 411 drives the suction cup part 420 to reciprocate stably along the Z-axis through the guide rail 413. The transverse moving part 412 is connected to the longitudinal moving part 411 through a connecting bracket or the like. The transverse moving part 412 is perpendicular to the Z-axis and is responsible for linear motion along the X-axis. Through the coordinated work of the longitudinal moving part 411 and the transverse moving part 412, the suction cup part 420 can move along the Z-axis and the X-axis.

[0091] Optionally, the coating device also includes a control circuit, which includes, but is not limited to, a PLC (Programmable Logic Controller), other types of controllers, or other control devices. Specifically, the suction cup assembly 400 can be used to pick up material after receiving a power-on signal or a material-picking signal output from the control circuit of the coating device. The range of motion of the suction cup assembly 420 is determined by the coordinated operation of the longitudinal moving part 411 and the lateral moving part 412, and the suction cup assembly 420 is driven to move between the material bin 520 and the conveying start end of the conveying assembly 100. After the longitudinal moving part 411 drives the suction cup part 420 to move downward along the Z-axis toward the material bin 520, and the lateral moving part 412 drives the suction cup part 420 to move to the left along the X-axis toward the material bin 520, the suction cup part 420 picks up the product 800 to be processed from the material bin 520; after the longitudinal moving part 411 drives the suction cup part to move upward along the Z-axis away from the material bin 520, the lateral moving part 412 drives the suction cup part 420 to move to the right along the X-axis away from the material bin 520 and toward the beginning of the conveying assembly 100, and after the suction cup part 420 moves above the fixture located at the beginning of the conveying assembly 100, the longitudinal moving part 411 drives the suction cup part 420 to move downward along the Z-axis toward the conveying assembly 100, and the suction cup part 420 releases the product 800 to be processed picked up onto the fixture 600 at the beginning of the conveying assembly 100.

[0092] Reference Figure 2In one specific embodiment, the conveying component 100 is a ring conveyor belt, and the beginning and end of the conveying are optionally arranged adjacent to each other or at the same position of the conveying component 100; the specific positions of the beginning and end of the conveying can be set according to actual conditions, and are not limited here.

[0093] Optionally, the circular conveyor belt includes, but is not limited to, a first conveyor segment 101 and a second conveyor segment 102, which are connected end to end to form a loop. Each of the first conveyor segment 101 and the second conveyor segment 102 has a conveying start end and a conveying end end. The conveying start end of the second conveyor segment 102 is connected to the conveying end end of the first conveyor segment 101. The conveying start end of the circular conveyor belt is located at the conveying start end of the first conveyor segment 101, and the conveying end end of the circular conveyor belt is located at the conveying end end of the second conveyor segment 102. Specifically, the first coating component 301, the product flipping component 200, the second coating component 302, etc., can be spaced along the X-axis on the first conveying section 101 (and on some of the conveying components 100 of the second conveying section 102), and at least one unloading station can be set on the second conveying section 102 (or on at least some of the conveying components 100 near the end of the conveying section 102) to complete the product performance test before unloading through manual quality inspection, machine inspection, etc., and / or, or to complete the unloading through manual unloading, machine unloading, etc.

[0094] Reference Figure 2 In one embodiment, the coating apparatus further includes a plurality of blocking members 110. At least one blocking member 110 is provided between the product flipping assembly 200 and the coating assembly 300 (first coating assembly 301, second coating assembly 302) along the conveying direction of the conveying assembly 100. The blocking member 110 can move upward or downward along the Z-axis. The blocking member 110 moves upward to block the fixture 600, or the blocking member 110 moves downward to release the fixture 600.

[0095] Optionally, in the embodiments of this application, blocking members 110 can be provided at the positions of the product flipping assembly 200, the coating assembly 300, the suction cup assembly 400, etc. The blocking members 110 are used to block the fixture 600, so as to control the fixture 600 to stay at the beginning of the conveyor belt, the corresponding workstation of the product flipping assembly 200, the coating assembly 300, the suction cup assembly 400, etc., and help control the corresponding processing steps. Multiple blocking members 110 can also be provided on both sides of the product flipping assembly 200, the coating assembly 300, the suction cup assembly 400, etc.; this arrangement is used to block the fixture 600 while preventing the fixture 600 from retreating due to rebound or other reasons caused by obstructed conveying, thus affecting the processing of the fixture 600 at the relevant workstation, and further optimizing processing efficiency and quality.

[0096] Understandably, the blocking member 110 is used to move upward when the fixture 600 is detected, thereby blocking the fixture 600. Specifically, it can be used to detect the fixture 600 on the conveying assembly 100 based on a position sensor or similar device provided on the conveying assembly 100 or on the blocking member 110, and the blocking member 110 moves upward when the fixture 600 is detected. In addition, the blocking member 110 can also be used to move upward based on a signal fed back when the previous process ends. The blocking member 110 is also used to move downward when a release signal is received, thereby releasing the fixture 600. Specifically, multiple stations are set along the conveyor assembly 100, corresponding to the first coating component 301, the product flipping component 200, the second coating component 302, the unloading station, the quality inspection station, etc. When the process of the current station is in progress (or when there is still a fixture 600 stuck at the next station), the control circuit of the coating device controls the corresponding blocking member 110 of the previous station to move up (or keep it in the rising state) until the corresponding station completes the corresponding coating process, flipping process, inspection process, unloading process, etc. (or until it is determined that there is no fixture 600 stuck at the next station), and outputs a release signal to control the blocking member 110 to move down and release the corresponding fixture 600.

[0097] In the embodiments of this application, a lifting device may be optionally configured corresponding to the blocking member 110, and the corresponding blocking member 110 may be moved up or down by the lifting device; or the lifting device such as the cylinder set for each workstation may be used as the blocking member 110 itself; the specific configuration may be determined according to actual conditions and is not limited here.

[0098] Reference Figures 6 to 8 Taking the fixture 600 located at the beginning of the conveyor as an example, the fixture 600 has 32 slots 610, which are specifically arranged in a matrix, with 4 columns arranged along the X-axis and 8 rows arranged along the Y-axis. The distance between two adjacent columns arranged along the X-axis is equal, and the distance between two adjacent rows arranged along the Y-axis is equal. The suction cup part 420 includes 16 suction cups, which are arranged in a matrix, with 2 columns arranged along the X-axis and 8 rows arranged along the Y-axis. The positions of the 16 suction cups correspond to the positions of the 16 slots 610 of the fixture 600 arranged along the X-axis near the left (or near the right). Specifically, the distance between the 4 slots in the same row is further defined as equal, and the distance between the 8 slots in the same column is equal, to facilitate material picking and processing. The hopper 520 has two rows of material troughs arranged along the X-axis. Each row has eight material troughs 521 arranged along the Y-axis. Each material trough 521 carries multiple products 800 to be processed arranged along the Z-axis. The positions of the 16 material troughs 521 correspond one-to-one with the positions of the 16 suction cups of the suction cup part 420.

[0099] The suction cup unit 420 specifically needs to perform two transfers. During the first transfer, after the suction cup unit 420 picks up the product to be processed 800 from the hopper 520, the longitudinal moving part 411 drives the suction cup unit 420 to move upward along the Z-axis away from the hopper 520. Then, the lateral moving part 412 drives the suction cup unit 420 to move along the X-axis to above the two rows of slots near the left (or right) side of the fixture at the beginning of the conveying process. The longitudinal moving part 411 then drives the suction cup unit 420 to move downward along the Z-axis near the conveying assembly 100. The suction cup unit 420 releases the product to be processed 800 picked up into the two rows of slots near the left (or right) side of the fixture 600. The second transfer can refer to the first transfer. The suction cup unit 420 releases the product to be processed 800 picked up into the two rows of slots near the right (or left) side of the fixture 600 until the slots of the fixture 600 at the beginning of the conveying process are filled.

[0100] Reference Figure 3 Furthermore, there are multiple flipping grippers 220, each flipping gripper 220 having a clamping position 2201, and the positions of the multiple clamping positions 2201 correspond one-to-one with the multiple slots 610 provided in the fixture 600. The product flipping assembly 200 is located in the middle of the first conveying section 101, the conveying start end of the conveying assembly extends along the Y-axis, and the first conveying section 101 of the conveying assembly extends at least partially along the X-axis. Optionally, each flipping gripper 220 has one or more gripping positions 2201. The product flipping assembly 200 includes two sets of flipping grippers arranged opposite each other along the X-axis. Each set includes four flipping grippers arranged along the Y-axis. When each flipping gripper 220 has two gripping positions 2201, each gripping position 2201 is used to grip a product 800 to be processed. The distance between the two gripping positions 2201 of the same flipping gripper 220, the distance between the two sets of flipping grippers arranged opposite each other along the X-axis, and the distance between two adjacent rows of fixture 600 arranged along the Y-axis are equal. The distance between two adjacent flipping grippers 220 arranged along the Y-axis is equal to the distance between two adjacent columns arranged along the X-axis.

[0101] Reference Figures 1 to 8 Taking the application of the coating device of this application to the coating of ceramic gaskets, for processing 32 ceramic gaskets at a time as an example, the specific implementation process is as follows:

[0102] Before the equipment is put into operation, ceramic pads of the corresponding specifications and quantities are picked up manually or packaged by machine and placed in the 32 material troughs 521 of the silo 520. When the equipment is in operation, one of the fixtures 600 is placed at the beginning of the conveying assembly 100, and the blocking member 110 near the beginning of the conveying assembly 100 moves and rises so that the fixture 600 stays at the beginning of the conveying assembly 100.

[0103] Then, the feeding unit 510 of the feeding assembly 500 drives the hopper 520 to move and rise. When the suction cup 420 moves close to the hopper 520, it drives the hopper 520 to rise to a preset height. Specifically, the suction cup 420 will pick up material twice, picking up 16 ceramic pads each time, thus meeting the feeding requirement of 32 ceramic pads. Specifically, the position of the suction cup assembly 400 (or the position of the top layer of the product to be processed 800 in the hopper 520) can be detected by a position detection component 530, such as a laser position sensor, located in the feeding assembly 500. This is used to output a detection signal when the suction cup 420 moves close to the hopper 520 (or to output a detection signal when the top layer of the ceramic pads to be processed in the hopper 520 is not at the preset highest position). The control circuit controls the feeding unit 510 to drive the hopper 520 to rise according to the detection signal. Each time material is retrieved, the longitudinal moving part 411 and the lateral moving part 412 of the suction cup assembly 400 drive the suction cup part 420 to switch between the hopper 520 and the conveying assembly 100. When the suction cup part 420 moves closer to the hopper 520, it picks up the product 800 to be processed from the hopper 520. When the suction cup part 420 moves closer to the conveying assembly 100, it releases the product 800 to be processed onto the fixture 600 at the beginning of the conveying process. This process is repeated until the fixture 600 at the beginning of the conveying process is full of ceramic pads to be processed, at which point the blocking member 110 at the beginning of the conveying process will move and descend.

[0104] The process involves manually picking up ceramic pads of the appropriate specifications and quantity, or by machine sorting, and placing them into a hopper 520. The hopper 520 can be configured with two rows of 16 spring-loaded feed slots 521. These slots are used to raise the hopper 520 to a preset height via a feeding unit 510 when the suction cup 420 moves to the picking position (or, to raise the hopper 520 to a preset height when the top layer of ceramic pads awaiting processing is not at the preset highest position). This ensures that the top layer of ceramic pads awaiting processing is always at the highest position of the hopper 520. The overall upward movement of the ceramic pads in the hopper 520 prepares for the next picking operation. The preset height of the hopper 520 can be adjusted according to the thickness of the ceramic pads.

[0105] After the blocking member 110 at the beginning of the conveying process moves and descends, the conveying assembly 100 moves the fixture 600 to the station corresponding to the first coating assembly 301. The blocking member 110 in the area where the first coating assembly 301 is located moves and rises to block the fixture 600. The steel mesh assembly 700 in the area corresponding to the first coating assembly 301 moves to the first position under the action of the corresponding lifting assembly and engages with the fixture 600 on the conveying assembly 100. Then, it moves to the second position to move the engaged fixture 600 closer to the first coating assembly 301. The scraper 310 of the first coating assembly 301 moves back and forth to coat the ceramic gasket to be processed, completing the coating process on the first coating surface (e.g., the front side). After the coating process on the first coating surface (e.g., the front side) is completed, the blocking member 110 in the area where the first coating assembly 301 is located will move and descend.

[0106] During the coating process, the first coating component 301 dispenses silicone grease quantitatively via a screw valve 330, and a linear module drives a scraper 310 to reciprocate the coating onto the ceramic pad to be processed, which is abutted against by the stencil assembly 700. After coating, the scraper 310 returns to its original position. The stencil 710 of the stencil assembly 700, positioned directly above the fixture 600, corresponding to the first coating component 301, can control the size of the coating area on the ceramic pad, and simultaneously control the stability and accuracy of the coating process.

[0107] After the blocking member 110, which is set in the area corresponding to the first coating component 301, moves and descends, the conveying component 100 drives the fixture 600 to move to the station corresponding to the product flipping component 200. The blocking member 110, which is set in the area corresponding to the product flipping component 200, moves and rises to block the fixture 600.

[0108] When the product flipping assembly 200 is in operation, the lifting cylinder 212 drives the flipping gripper 220 to move and descend along the Z-axis, so that the flipping gripper 220 moves close to the fixture 600 on the conveying assembly 100. After the flipping gripper 220 clamps the product 800 to be processed at the corresponding position, the shifting cylinder 211 drives the flipping gripper 220 to move along the Y-axis, so that the flipping gripper 220 moves away from the fixture 600. The rotating cylinder 213 drives the flipping gripper 220 to rotate, so as to flip the coating surface of the product 800 to be processed from the first coating surface to the second coating surface. After the flipping process is completed, the shifting cylinder 211 drives the flipping gripper 220 to move along the Y-axis, so that the flipping gripper 220 moves close to the fixture 600, and the flipping gripper 220 releases the product 800 to be processed at the corresponding position.

[0109] After the flipping process is completed, the blocking member 110 set in the area where the product flipping component 200 is located moves and descends. The conveying component 100 drives the fixture 600 to move to the station corresponding to the second coating component 302. The blocking member 110 set in the area where the second coating component 302 is located moves and rises to block the fixture 600, and the second coating component 302 completes the coating process of the second coating surface (such as the back side). This part can be referred to in detail to the aforementioned steps of completing the coating process of the first coating surface (such as the front side) through the first coating component 301, and will not be repeated here.

[0110] After the second coating component 302 completes the second coating of the ceramic gasket to be processed, the blocking component 110 set in the area where the second coating component 302 is located moves and descends, and the conveying component 100 drives the fixture 600 to move to realize the unloading.

[0111] The jig 600 is cyclically moved via a circular conveyor belt. The jig 600 sequentially passes through the loading stations corresponding to the feeding assembly 500 and suction cup assembly 400 in the first conveyor section 101, the front coating station corresponding to the first coating assembly 301, the flipping station corresponding to the product flipping assembly 200, and the reverse coating station corresponding to the second coating assembly 302. Afterward, it flows into the second conveyor section 102 of the circular conveyor belt, where the ceramic gaskets are removed manually or by machine and placed into the inverter product or proceed to the next process. After the ceramic gaskets are removed from the jig 600, the empty jig 600 is again conveyed via the circular conveyor belt, passing through the loading station, front coating station, flipping station, and reverse coating station again, in a continuous cycle.

[0112] When the fixture 600, fully loaded with coated ceramic pads, passes through the second conveyor section 102 of the circular conveyor belt, the corresponding blocking component 110 is moved upward by manual operation of buttons or machine detection to block the fixture 600. After the ceramic pads are removed, the blocking component 110 is moved downward by manual operation of buttons or machine detection again, and the conveying component 100 moves the fixture 600 so that the fixture 600 can flow to the next stage.

[0113] To accommodate the coating of different ceramic gaskets, the fixture 600 can be replaced, and the overall dimensions and shape of different fixtures 600 can be identical. Depending on the processing requirements, the dimensions, shape, and grooves 610 (such as contoured grooves) of different fixtures 600 can be the same or different. Specifically, this can be achieved by changing the fixture 600, stencil assembly 700, feeding assembly 500, hopper 520, etc., corresponding to the product model, and even by changing the corresponding coating material and coating path, to suit the coating processing of ceramic gasket products of different specifications.

[0114] The coating device shown in this application, applied to the double-sided coating process of ceramic gaskets, can complete the double-sided coating of 32 ceramic gaskets at one time. The mechanical structure is aesthetically pleasing and compact. The use of a circular conveyor belt can reduce the accumulation and waiting time of the jig 600 during the conveying process, improve processing efficiency and coating quality, and prevent the jig 600 or other materials from falling during the conveying process, effectively improving operational safety, while ensuring the stability and reliability of equipment operation.

[0115] The coordinated operation of the circular conveyor belt, suction cup assembly 400, feeding assembly 500, first coating assembly 301, product flipping assembly 200, and second coating assembly 302 enables highly efficient, fully automated double-sided coating of ceramic gaskets. This not only significantly improves production efficiency but also meets the production cycle requirements of the assembly line. The stencil 710 not only increases coating compatibility and quality but also enables high-quality completion of different coating requirements on both sides. When the suction cup section 420 moves to the material picking position, the feeding assembly 500 raises the hopper 520 to a preset height, ensuring that the top ceramic gasket is always at the highest position in the hopper 520, effectively reducing the number of feeding operations and labor costs. Furthermore, the entire equipment is highly compatible; by changing different fixtures 600, hoppers 520, and stencil assemblies 700, it can meet the coating needs of ceramic gaskets of different specifications, effectively increasing the equipment's practicality.

[0116] There are multiple product flipping components 200. Along the conveying direction of the conveying component 100, a product flipping component 200 is provided between two adjacent coating components 300. The specific implementation of the coating device for processing other products 800 with multiple coating surfaces, as well as the implementation of the coating device when it is specifically applied to the processing of other electrical components or the coating processing of other products 800 with different quantities and types, can refer to the foregoing embodiments and be adjusted accordingly. They will not be described in detail here.

[0117] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
