[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 3As shown, an embodiment of the present invention provides a spraying device, which includes a transport assembly 10, a frame 20, and a spraying unit. The transport assembly 10 includes a conveyor belt 11, which is used to transport products to be sprayed. The frame 20 includes multiple support units 21, which are located on one side of the conveyor belt 11 in the transport direction and are arranged sequentially along the transport direction of the conveyor belt 11. Adjacent support units 21 are detachably connected. The spraying unit includes a cleaning assembly 31, a spraying assembly 32, and a drying assembly 33, which are arranged sequentially along the transport direction of the conveyor belt 11. The cleaning assembly 31 is used to spray impurities and dirt on the products, the spraying assembly 32 is used to spray the products with a spraying agent, and the drying assembly 33 is used to dry the coating sprayed on the products. The cleaning assembly 31, the spraying assembly 32, and the drying assembly 33 are respectively arranged on different support units 21 and are all located above the conveyor belt 11. The cleaning assembly 31, the spraying assembly 32, and the drying assembly 33 cooperate with each other to spray the products.

[0034] Specifically, the support unit 21 is configured as a box structure, which can improve the support strength and stability of the support unit 21. In other embodiments, the specific structure of the support unit 21 is not limited, and can be a combined support structure such as a frame or a column.

[0035] The products are two components of an air conditioner, namely the evaporator and condenser. The parts to be sprayed are the elbows on the two components. The spraying agent sprayed by the cleaning component 31 is an aqueous solution, and the spraying agent sprayed by the spraying component 32 on the product is an antiseptic liquid. In other embodiments, the product can be any object requiring spraying, and the spraying agent can be other liquids.

[0036] The present invention provides a plurality of support units 21, wherein the cleaning component 31, the spraying component 32 and the drying component 33 cooperate with each other to spray the product. The frame 20 includes a plurality of support units 21, and the cleaning component 31, the spraying component 32 and the drying component 33 are respectively arranged on different support units 21. Two adjacent support units 21 can be detachably connected. The support units 21 are used to separate the spraying equipment into multiple independent functional modules such as cleaning, spraying and drying. Compared with the prior art, the frame is designed as an integral structure. When some components fail, the operator needs to disassemble and reset the entire frame. In the present application, through the above arrangement, when one of the modules fails, it is not necessary to disassemble the entire machine. It is only necessary to remove the corresponding support unit 21 from the frame 20. The module with the failure can be quickly disassembled, replaced or repaired separately. In this way, different functional modules can be independently disassembled and maintained, which not only enhances the flexibility and practicality of the equipment, but also reduces the maintenance complexity of the equipment, reduces the operator's physical labor and disassembly time, thereby shortening the equipment's downtime maintenance cycle and improving the equipment's maintenance efficiency and production efficiency.

[0037] In this application, the direction of the X-axis is defined as the first horizontal direction, that is, the transport direction of the conveyor belt 11. The length direction of the conveyor belt 11 is the same as the transport direction. The direction of the Y-axis is defined as the second horizontal direction, that is, the width direction of the conveyor belt 11. The plane formed by the X-axis and the Y-axis is a horizontal plane, and the direction of the Z-axis is a vertical direction.

[0038] Furthermore, the frame 20 includes a connecting member. The support units 21 are provided with a first connecting structure and a second connecting structure. The first connecting structure of one support unit 21 is connected to the second connecting structure of an adjacent support unit 21 via the connecting member, and the first connecting structure and the second connecting structure are each detachably connected to the connecting member. The detachable connection between two adjacent support units 21 via the connecting member simplifies the assembly and disassembly of adjacent support units 21. Operators do not need to move the support units 21 during assembly and disassembly. They only need to remove the connecting member from the two adjacent support units 21 to complete the separation of the adjacent support units 21, achieving rapid assembly and disassembly and maintenance.

[0039] like Figure 4 As shown, the two ends of the support unit 21 along the transport direction of the conveyor belt 11 are respectively a first end and a second end. The first end is provided with a plurality of first through holes 211, and the connecting member is provided with a plurality of third through holes. The plurality of third through holes are arranged in a one-to-one correspondence with the plurality of first through holes 211. The third through holes are engaged with the first through holes 211 via a first fastener, and the plurality of first through holes 211 form a first connection structure. The second end is provided with a plurality of second through holes 212, and the connecting member is provided with a plurality of fourth through holes. The plurality of fourth through holes are arranged in a one-to-one correspondence with the plurality of second through holes 212. The fourth through holes are engaged with the second through holes 212 via a second fastener, and the plurality of second through holes 212 form a second connection structure. By connecting multiple fasteners with multiple through holes, operators only need simple tools to quickly complete disassembly and assembly. In addition, the multiple hole positions can improve the stability of the connection between two adjacent support units 21, preventing the connection from loosening due to vibration or external impact during long-term operation of the equipment. The through holes are arranged at the ends of the support unit 21, which not only facilitates connection and reduces the size of the connecting parts, but also ensures the supporting strength of the middle part of the support unit 21, avoiding too many through holes in the middle part of the support unit 21 causing the structural strength to be reduced or broken.

[0040] In the present application, the number and arrangement of the first through holes 211 and the second through holes 212 are not limited.

[0041] In this embodiment, twelve first through holes 211 are provided, divided into two groups, each group including six first through holes 211. The six first through holes 211 in each group are spaced apart in the vertical direction, and the two groups of first through holes 211 are spaced apart along the transport direction of the conveyor belt 11. This allows the connection position of two adjacent support units 21 to be adjusted by connecting different groups of through holes with connectors, thereby meeting the various size requirements of the rack 20. The number and arrangement of the second through holes 212 are the same as those of the first through holes 211, thereby ensuring uniform force on both ends of the support unit 21 and reducing deformation of the support unit 21.

[0042] like Figure 5 and Figure 6 As shown, the conveyor belt 11 has a first side 111 and a second side 112 along its width. The portion of the product to be sprayed extends from the first side 111 toward the second side 112. Since the portion to be sprayed protrudes from the conveyor belt 11, the equipment can directly target these portions for spraying, preventing the spray sprayed on the product from dripping onto the conveyor belt 11. This also reduces the amount of spray sprayed on the product that splashes on the conveyor belt 11. This design can reduce the risk of excessive spray adhering to the equipment, which can cause long-term accumulation and hardening into lumps that scratch the surfaces of the two devices, causing damage to both devices. It also facilitates daily cleaning and extends the service life of the equipment. The cleaning assembly 31, the spray assembly 32, and at least a portion of the support unit 21 are arranged near the first side 111. Placing the portion to be sprayed on one side of the conveyor belt 11 shortens the transmission distance of the workpiece from cleaning, spraying, to drying, reduces waiting time, improves the overall efficiency of the production line, and allows for better control of the spray angle and range to ensure the uniformity and integrity of the coating.

[0043] Specifically, induction sensors are provided on both sides of the conveyor belt 11. The induction sensors are provided upstream of the cleaning component 31. The induction sensors are electrically connected to the cleaning component 31. The products on the conveyor belt 11 are sensed by the induction sensors. When the induction sensors sense the products, the cleaning component 31 is started to work. The spraying component 32 and the drying component 33 are in a continuous working state that is always turned on when the spraying equipment is working.

[0044] like Figure 6As shown, the transport assembly 10 includes a support frame 12, a first chain 13, a second chain, and a drive unit. The first chain 13 and the second chain are both rotatably mounted on the support frame 12 along the transport direction of the conveyor belt 11. Both the first chain 13 and the second chain are drive-connected to the conveyor belt 11, with the first chain 13 positioned near the first side 111 and the second chain positioned near the second side 112. Along the width of the conveyor belt 11, the distance between the centerline of the support frame 12 along the transport direction and the first chain 13 is smaller than the distance between the centerline of the support frame 12 along the transport direction and the second chain. Compared to the prior art, the first chain 13 and the second chain are symmetrically positioned relative to the centerline of the support frame 12 along the transport direction. The antiseptic liquid from the spraying equipment can splash onto the chains. The antiseptic liquid solidified on the chains is highly corrosive in a humid environment. Corroded chains can make unusual noises and vibrate, affecting their normal operation. Over time, chain link breakage can occur. The above-described design of the present application can increase the horizontal distance between the first chain 13 and the first side 111, reducing the splashing of the spray on the first chain 13, thereby reducing the corrosion of the first chain 13 by the spray, and ensuring the normal operation of the chain. The drive unit is disposed at the end of the support frame 12 and is driven by the first chain 13 and the second chain respectively, so that the first chain 13 and the second chain rotate synchronously.

[0045] Furthermore, the conveyor belt 11 includes a plurality of chain plates 14, which are spaced apart along the transport direction of the conveyor belt 11, and there are gaps between adjacent chain plates 14, so that the splashed spray can drip through the gaps to avoid accumulation and solidification on the conveyor belt 11, thereby avoiding scratches and damage to the product, and at the same time reducing the residual amount of spray on the conveyor belt 11, reducing damage to the conveyor belt 11 itself, and making cleaning more convenient. The chain plate 14 is sequentially distributed with a main body 141 and an extension portion 142 along the width direction of the conveyor belt 11. The main body 141 is connected to the first chain 13 and the second chain respectively. At least part of the extension portion 142 is located outside the support frame 12. The end of the extension portion 142 away from the main body 141 forms a first side 111. The extension portion 142 can support the position of the product on the conveyor belt 11. The end of the main body 141 away from the extension portion 142 forms a second side 112. The extension portion 142 provides additional support area, so that the product is placed further away from the first chain 13, which can further reduce the corrosion of the first chain 13 by the spray agent splashed on the product.

[0046] Specifically, a plurality of chain plates 14 are arranged at intervals around the outer circumference of the first chain 13 and the second chain along the transport direction of the conveyor belt 11, and the chain plates 14 are connected to the first chain 13 and the second chain through connecting blocks at both ends along the width of the conveyor belt 11.

[0047] like Figure 1As shown, the spraying unit also includes a first purge assembly and a second purge assembly 34. The first purge assembly and the second purge assembly 34 are respectively arranged on different support units 21 and are arranged near the first side 111. The first purge assembly is located between the cleaning assembly 31 and the spraying assembly 32 and is used to remove residual moisture and impurities on the surfaces of the two components to ensure that the subsequent spraying process can spray evenly. The second purge assembly 34 is located between the spraying assembly 32 and the drying assembly 33 and is used to accelerate the drying of the coating on the surface of the two components. The second purge assembly 34 includes a first exhaust component 341, and part of the first exhaust component 341 is arranged on the top of the cover body 22.

[0048] In the present application, there is no limitation on the structures of the first purge assembly and the second purge assembly 34 , which are existing technologies and can achieve the purge of the product.

[0049] Furthermore, the spraying equipment also includes a liquid collection structure, which is arranged on the support unit 21 and is located below the part of the product to be sprayed. Specifically, the liquid collection structure is arranged close to the first side 111. The liquid collection structure is used to receive the splashed waste liquid. By capturing and collecting these waste liquids, the waste liquid can be prevented from causing secondary pollution to the equipment and the environment, and it is also beneficial to the recovery and treatment of the waste liquid.

[0050] like Figures 2 to 4 As shown, the liquid collecting structure includes a plurality of liquid collecting parts 35 and a movable part 36. Among them, the plurality of liquid collecting parts 35 are respectively arranged on different support units 21, and the plurality of liquid collecting parts 35 are respectively arranged corresponding to the spraying units. The liquid collecting part 35 corresponding to the spraying assembly 32 is the first liquid collecting tank 351. The first liquid collecting part 35 is located on the movable part 36. The support unit 21 corresponding to the spraying assembly 32 has an opening on the side away from the conveyor belt 11. The movable part 36 can enter or leave the opening to transfer the first liquid collecting part 35. The spraying agent sprayed by the spraying assembly 32 has a greater damage and impact on the equipment. Through the above-mentioned setting, the operator can transfer the collected waste liquid of the spraying assembly 32 to the designated treatment area in time, thereby improving the efficiency and convenience of waste liquid collection, reducing production downtime, and also reducing the labor intensity of the operator.

[0051] It is understood that multiple liquid collection members 35 are provided corresponding to the cleaning assembly 31, the spraying assembly 32, the first purge assembly, and the second purge assembly 34, respectively. In other embodiments of the present application, if there are other components that generate splashing waste liquid, liquid collection members 35 may also be provided correspondingly. Furthermore, the liquid collection members 35 can be provided one-to-one with the above-mentioned components, or multiple liquid collection members 35 can be provided for a single component.

[0052] like Figures 2 to 5As shown, the frame 20 includes multiple covers 22, each of which has a cavity 221. The extension direction of the cavity 221 is the same as the transportation direction of the conveyor belt 11. The conveyor belt 11 is arranged in the cavity 221, and part of the spraying unit is arranged in the cavity 221. The provision of the cover 22 isolates the spraying operation area, reduces the impact of the external environment on the spraying process, improves the spraying quality of the coating, and also protects the operator from the danger of spraying agent splashing, thereby improving the safety of the equipment.

[0053] Among them, the cover body 22 is respectively provided with openable and closable movable doors on both sides along the transport direction of the conveyor belt 11, and the operator can observe the conditions of the working components inside the cover body 22 by opening the movable doors.

[0054] Specifically, multiple support units 21 are distributed on both sides of the conveyor belt 11 in the transport direction. The bottom of the cover 22 is located on both ends of the width of the conveyor belt 11, respectively, on the support units 21 located on both sides of the conveyor belt 11 in the transport direction. This design divides the frame 20 into two parts through the support units 21 on both sides of the conveyor belt 11 in the transport direction: support units 21 near the first side 111 and support units 21 near the second side 112. The support units 21 near the first side 111 are used to support the cover 22 and accommodate the multiple liquid collection members 35. The support units 21 are larger than those near the second side 112. The support units 21 near the second side 112 are used to support the cover 22. This allows for the functional division of the support units 21, facilitating the selection and design of the size and structure of the support units 21 according to different needs, thereby optimizing the structure of the frame 20. At the same time, the frame 20 is divided into two parts by the conveyor belt 11. The frame 20 has no connection with the conveyor belt 11. When the conveyor belt 11 needs to be replaced, there is no need to disassemble the frame 20. The conveyor belt 11 can be directly pushed out of the cavity 221, which increases the replacement space of the conveyor belt 11 and the chain and improves the convenience of chain replacement.

[0055] It is understandable that one cover 22 may correspond to two support units located on both sides of the conveyor belt 11, or may correspond to multiple support units 21. Components with different functions, such as the cleaning component 31 in the spraying unit, may be arranged in one cover 22 or in multiple covers 22.

[0056] like Figure 7As shown, the cleaning assembly 31 includes a spray gun 310, which is used to spray a coating agent onto a product. The cleaning assembly 31 also includes a first linear module 311, a second linear module 312, a slide rail 313, and a flip assembly 314. The first linear module 311 is used to adjust the position of the spray gun 310 along a first horizontal direction, the slide rail 313 is used to adjust the position of the spray gun 310 along a second horizontal direction, the second linear module 312 is used to adjust the vertical position of the spray gun 310, and the flip assembly 314 is used to adjust the rotation angle of the spray gun 310. The spray gun 310, the first linear module 311, the second linear module 312, the slide rail 313, and the flip assembly 314 are all disposed within the housing 22. These components are all conventional and will not be described in detail here.

[0057] like Figure 8 As shown, the spray assembly 32 includes a spray head 320, a first adjusting member 323 and a second adjusting member 322. The spray head 320, the first adjusting member 323 and the second adjusting member 322 are all arranged in the cover body 22. The spray assembly 32 also includes a second exhaust component 321, part of which is arranged on the top of the cover body 22. The first adjusting member 323 is used to adjust the position of the spray head 320 in the second horizontal direction, and the second adjusting member 322 is used to adjust the position of the spray head 320 in the vertical direction. The spray head 320 is rotatably connected to the second adjusting member 322 to adjust the rotation angle of the spray head 320. The spray head 320 is used to spray the spray agent onto the product. The above components are all prior art and will not be described in detail here.

[0058] Preferably, two spraying assemblies 32 are sequentially arranged along the transport direction of the conveyor belt 11, and each spraying assembly 32 is provided with two spray heads 320 to ensure the integrity of the spraying on the surfaces of the two devices.

[0059] like Figures 1 to 3 As shown, the drying component 33 includes a third exhaust component 332 and a plurality of sequentially distributed wind-heat dryers 331. The conveyor belt 11 is passed through the wind-heat dryer, and part of the third exhaust component 332 is located outside the cover 22. The drying component 33 can accelerate the curing of the external coating of the product, improve the hardness and wear resistance of the coating, thereby ensuring the stability of the coating performance, and can also effectively prevent the problem of bubbles falling off due to the coating not being dry, thereby ensuring the performance of the product. In other embodiments, the type of dryer is not limited, and it can be infrared heating, electric heating, etc. The above components are all existing technologies and will not be described in detail here.

[0060] Furthermore, the spraying unit includes a liquid storage mechanism and an escalator 37. The liquid storage mechanism is arranged at the top of the cover body 22. The liquid storage mechanism can provide spraying agent for the cleaning component 31 and the spraying component 32. The escalator 37 is located outside the frame 20 and is arranged corresponding to the liquid storage mechanism. The escalator 37 is used for the operator to replace the spraying agent in the liquid storage mechanism and to facilitate the operator to repair the liquid storage mechanism.

[0061] Specifically, the liquid storage mechanism includes a first liquid storage tank 41 and three second liquid storage tanks 42. The first liquid storage tank 41 is used to provide spraying agent for the spray gun 310, and the second liquid storage tank 42 is used to provide spraying agent for the spray head 320. In other embodiments, the number of the first liquid storage tank 41 and the second liquid storage tank 42 is not limited.

[0062] In this application, a running gear is provided at the bottom of each of the support unit 21 and the conveyor belt 11. The running gear is used to adjust the horizontal position of the support unit 21 and the conveyor belt 11. The provision of the running gear allows the equipment to be flexibly adjusted according to actual production needs, enabling it to adapt to different production line configurations and changes in product size, thereby improving equipment utilization and production line flexibility.

[0063] Specifically, the walking part includes a plurality of rollers, which are respectively arranged at the bottom of the support unit 21 and the bottom of the support frame 12, so as to facilitate the movement and adjustment of the positions of the support unit 21 and the conveyor belt 11.

[0064] The operation process of the spraying equipment provided in this application is as follows:

[0065] After the two devices are placed in the spraying equipment, they are transported to the cleaning component 31 through the conveyor belt 11. When the induction sensor detects that the two devices have passed, the cleaning component 31 is started, and water vapor is sprayed through the spray gun 310 to clean the two devices, and then the surfaces of the two devices are purged through the first purge component; then they continue to be transported to the spraying component 32, and the anti-corrosion liquid is sprayed onto the two devices through the nozzle 320 on the spraying component 32 to carry out the anti-corrosion spraying operation, and then the surfaces of the two devices are purged through the second purge component 34; then they continue to be transported to the drying component 33, and the drying component 33 can dry the anti-corrosion liquid on the surface of the two devices by adjusting the temperature, so as to achieve the drying effect.

[0066] The technical solution provided by this application has the following advantages:

[0067] 1. Through the modular design of the rack, the rack can be split into multiple supporting units. If a single functional module is damaged during long-term operation, it can be quickly disassembled and repaired separately.

[0068] Second, by setting extensions on the conveyor belt and changing the installation position of the chain, the chain can be effectively prevented from shaking due to corrosion by the anti-corrosion fluid, so that the equipment can work stably for a long time and improve the overall efficiency of the production line;

[0069] 3. The frame is divided into two parts on both sides of the conveyor belt, and rollers are set at the bottom of the conveyor belt, so the conveyor belt can be directly pulled out of the spraying equipment as a whole, solving the problem of difficulty in replacing the conveyor belt chain in a small space.
