Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0039] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0040] As described in the background section, existing techniques for assembling fire-viewing windows require manual placement of mica sheets on the front cover plate, followed by pressing the mica sheets onto the front cover plate using a pressure plate, and then spot welding the pressure plate to the front cover plate. Finally, the inner lining plate is welded to the side of the front cover plate away from the mica sheets, thus completing the assembly of the fire-viewing window. However, manual assembly of fire-viewing windows requires significant manpower and has low production efficiency.

[0041] To address the aforementioned technical problems, this application provides an assembly device for a water heater cover plate assembly, comprising a first feeding unit, a second feeding unit, a first welding unit, a flattening unit, and a second welding unit. The cover plate assembly includes a front cover plate, a mica component, a pressure plate, and an inner liner plate. The mica component is fixed to the front cover plate by the pressure plate, and the inner liner plate is fixed to the side of the front cover plate opposite to the mica component. During assembly, the operator first pre-installs the mica component on the front cover plate and then places it in the first feeding unit to replenish sufficient workpieces. Next, the pressure plate is placed in the second feeding unit, which feeds the pressure plate to the position corresponding to the mica component on the front cover plate. The first welding unit welds the pressure plate to the front cover plate, thereby fixing the mica component to the front cover plate. The flattening unit then flattens the pressure plate to ensure the flatness of the cover plate assembly surface. Finally, the workpiece is conveyed to the second welding unit, where the inner liner plate is placed on the side of the front cover plate opposite to the mica component, and the second welding unit welds the inner liner plate to the front cover plate to obtain the cover plate assembly. Therefore, the assembly equipment for the cover plate assembly of the water heater provided in this application embodiment is beneficial to improving the automation level of the cover plate assembly process, saving the manpower required for cover plate assembly, and improving the assembly efficiency of the cover plate assembly.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0043] It should be noted that the assembly equipment for the cover plate assembly of the water heater provided in this application embodiment can be applied to various water heater production systems.

[0044] See Figure 1 and Figure 3 As shown in the figure, this application embodiment provides an assembly device 100 for a cover plate assembly 200 for a water heater. The cover plate assembly 200 includes a front cover plate 210, a mica component 220, a pressure plate 230, and an inner liner plate 240. The mica component 220 is fixed to the front cover plate 210 by the pressure plate 230, and the inner liner plate 240 is fixed to the side of the front cover plate 210 away from the mica component 220.

[0045] The assembly equipment 100 includes a first feeding unit 110, a second feeding unit 120, a first welding unit 130, a flattening unit 140, and a second welding unit 150. The first feeding unit 110 is used to feed the front cover plate 210 and mica component 220 of the cover plate assembly 200. The second feeding unit 120 is used to feed the pressure plate 230 of the cover plate assembly 200 to a preset position on the front cover plate 210. The first welding unit 130 is used to weld the pressure plate 230 and the front cover plate 210. The flattening unit 140 is used to flatten the welded pressure plate 230. The second welding unit 150 is used to weld the inner liner plate 240 of the cover plate assembly 200 to the front cover plate 210. The first feeding unit 110, the second feeding unit 120, the first welding unit 130, the flattening unit 140, and the second welding unit 150 are arranged sequentially along the workpiece transport path.

[0046] In this embodiment, since the mica sheet and pressure plate 230 are small in size and require high installation accuracy, a first feeding unit 110 and a second feeding unit 120 are required. The operator needs to place the mica sheet on the corresponding position of the front cover plate 210 and then put it into the first feeding unit 110. At the same time, before the assembly equipment 100 is started, a sufficient number of pressure plates 230 need to be prepared in the second feeding unit 120. After the second feeding unit 120 accurately feeds the pressure plates 230 to the preset position, the first welding unit 130 welds the pressure plates 230 onto the front cover plate 210. Compared with the prior art of manually placing the pressure plates 230 and then welding, the second feeding unit 120 of this embodiment can automatically feed the plates, thereby effectively saving manpower and improving assembly efficiency. It also helps to improve the installation accuracy of the pressure plates 230, thereby improving the yield of the cover plate assembly 200.

[0047] Furthermore, after the first welding unit 130 completes welding, the flattening unit 140 flattens the pressure plate 230, thereby ensuring the flatness of the surface of the cover plate assembly 200, which is conducive to improving the stability of the connection between the pressure plate 230 and the front cover plate 210, and thus ensuring the stability of the mica component 220.

[0048] After the flattening unit 140 flattens the pressure plate 230, the workpiece is flipped over and transferred to the second welding unit 150. The second welding unit 150 welds the inner liner 240 to the side of the front cover plate 210 away from the mica part 220 to obtain the cover plate assembly 200.

[0049] It should be noted that, due to the relatively large overall size of the inner liner plate 240, the assembly precision requirements for the inner liner plate 240 are relatively lower compared to the pressure plate 230. Furthermore, after welding by the second welding unit 150, the cover plate assembly 200 can be directly unloaded. Therefore, the worker responsible for unloading can place the inner liner plate 240 on the front cover plate 210 at the second welding unit 150, and then the second welding unit 150 will perform the welding. After welding, the worker can remove the cover plate assembly 200 for unloading, completing this operation without the need for additional personnel. Alternatively, a loading assembly can be set up on the second welding unit 150, pre-positioning multiple inner liner plates 240 within it. When the workpiece is transferred to the second welding unit 150, the loading assembly places the inner liner plate 240 in a preset position and then welds it onto the front cover plate 210, thereby further improving the automation level of the cover plate assembly 200 assembly and increasing its assembly precision and efficiency. Of course, the specific feeding method of the inner lining plate 240 is not limited in this embodiment of the application, and can be reasonably selected according to actual production needs.

[0050] Therefore, the assembly equipment 100 in this application embodiment helps to save manpower required for assembling the cover plate assembly 200, improve the assembly efficiency of the cover plate assembly 200, ensure the yield of the cover plate assembly 200, and thus improve the overall production efficiency of the water heater production system and reduce production costs.

[0051] See also some of the possible implementation methods. Figure 1 and Figure 3 As shown, the first welding unit 130 of this application embodiment includes a first worktable 131, a welding arm 132 and a welding head. The first worktable 131 is used to place the workpiece; the welding arm 132 is movably disposed on the first worktable 131 and has multiple degrees of freedom of movement; the welding head is disposed at the free end of the welding arm 132 and is used to weld the pressure plate 230 and the front cover plate 210.

[0052] Thus, the first worktable 131 provides a stable platform for placing the workpiece, ensuring that the position of the workpiece is fixed and not easily moved during the welding process. The first worktable 131 can also be equipped with clamping components and other fixing structures to fix the front cover plate 210 on the first worktable 131 during the welding process, thereby ensuring the accuracy of the relative position between the pressure plate 230 and the front cover plate 210, and thus ensuring the precision and stability of the welding.

[0053] Furthermore, the welding arm 132 is movably mounted on the welding worktable and has multiple degrees of freedom of movement. Therefore, the welding arm 132 can flexibly adjust its position and angle in three-dimensional space to adapt to workpieces of different shapes and sizes and meet different welding requirements. This improves the adaptability and flexibility of the first welding unit 130. The assembly equipment 100 completes the assembly of different models of cover plate components 200, expands the application range of the assembly equipment 100, and saves the production cost of water heaters.

[0054] Furthermore, the welding head, through the flexible adjustment of the welding arm 132, can be precisely positioned at the welding point, achieving a high-quality welded connection. This improves the welding efficiency of the first welding unit 130, while ensuring the stability and consistency of the welding process, thus enhancing the assembly quality and reliability of the entire cover plate assembly 200.

[0055] In some embodiments, the second welding unit 150 may be configured to have at least a partial structure that is the same as the first welding unit 130 in order to ensure the welding quality and welding efficiency between the inner liner plate 240 and the front cover plate 210. Of course, the workbench, welding head and welding arm 132 of the second welding unit 150 need to be appropriately adjusted according to the specific shape of the inner liner plate 240 and the welding method. This application embodiment does not limit this.

[0056] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 3 As shown, the flattening unit 140 of this application embodiment includes a second worktable 141, a mounting base 142, a support column 143, a pressure head 144, and a driving member 145. The second worktable 141 is used to place workpieces; the mounting base 142 is located on the upper side of the second worktable 141 and defines a working space between the two; the support column 143 is disposed between the second worktable 141 and the mounting base 142 and is used to support the mounting base 142; the pressure head 144 is vertically and vertically disposed in the working space and is used to apply pressure to the pressure plate 230; the driving member 145 is disposed on the mounting base 142 and is used to drive the pressure head 144 to move up and down.

[0057] In practical implementation, the second worktable 141 provides a stable placement platform for the front cover plate 210, ensuring that the position of the workpiece is fixed and not easily moved during the flattening process. At the same time, the mounting base 142 is located on the upper side of the second worktable 141, forming a working space between the two. The working space provides sufficient space for the lifting and lowering movement of the pressure head 144, which helps to ensure the safety and independence of the pressure head 144 during the pressure application process and reduces the interference of external factors on the riveting accuracy.

[0058] In addition, the support column 143 is located between the second workbench 141 and the mounting base 142, providing a certain degree of support and helping to ensure the stability of the mounting base 142. It also ensures the overall structural strength of the flattening unit 140, allowing the mounting base 142 to withstand greater pressure during the flattening process without deformation or displacement. The driving component 145 drives the pressure head 144 to rise and fall, enabling the pressure head 144 to accurately align with the pressure plate 230 according to the preset pressure and speed, and apply sufficient pressure to complete the flattening operation. This helps improve the connection quality between the pressure plate 230 and the front cover plate 210.

[0059] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the mounting base 142 of this application embodiment is provided with a movable hole that extends through its own thickness direction; the driving member 145 includes a driving body and a piston member. The driving body is located on the side of the mounting base 142 facing away from the second worktable 141, and the piston passes through the movable hole and is connected to the pressure head 144.

[0060] Understandably, the movable hole provides a movement channel for the piston, allowing it to move smoothly up and down within the hole. The drive unit is mounted on the side of the mounting base 142 facing away from the second worktable 141, which helps avoid occupying workspace and also facilitates maintenance and repair. When the drive unit is operating, it transmits power to the pressure head 144 via the piston, enabling the pressure head 144 to move up and down at a preset speed and pressure. This ensures that the pressure head 144 can accurately apply pressure to the pressure plate 230, improving the riveting effect of the flattening unit 140.

[0061] See also some of the possible implementation methods. Figure 1 and Figure 3 As shown, the embodiments of this application also include a workpiece transfer unit 160, which is used to transfer the workpiece from the first feeding unit 110 to the second feeding unit 120, the first welding unit 130, the flattening unit 140 and the second welding unit 150 in sequence.

[0062] In practice, the workpiece can be transferred and transported through the workpiece transfer unit 160, thereby improving the automation level of the assembly equipment 100 and the assembly efficiency of the cover plate assembly 200.

[0063] It should be noted that after the first feeding unit 110 completes feeding, the workpiece transfer unit 160 can transfer the workpiece to the second feeding unit 120. After the second feeding unit 120 feeds the pressure plate 230 to the preset position, the workpiece transfer unit 160 continues to transfer the workpiece to the first welding unit 130. Alternatively, after the first feeding unit 110 completes feeding, the workpiece transfer unit 160 can also directly transfer the workpiece to the first welding unit 130, and the second feeding unit 120 can feed the workpiece to the first welding unit 130. The specific transfer method is not limited in this application embodiment, and can be reasonably selected according to the specific structure of the feeding device of the second feeding unit 120.

[0064] Furthermore, transferring the workpiece through the workpiece transfer unit 160 can prevent workers from directly contacting the first welding unit 130, thereby reducing the risk of injury to workers due to operational errors or equipment malfunctions, and improving the safety of the assembly equipment 100.

[0065] See also some of the possible implementation methods. Figure 1 and Figure 3 As shown, the workpiece transfer unit 160 of this application embodiment includes: a frame 161 and a moving part 162. The extension path of the frame 161 passes through at least the first loading unit 110, the second loading unit 120 and the first welding unit 130. The moving part 162 moves along the extension path of the frame 161 and is used to carry and transfer workpieces.

[0066] In some embodiments, the movable member 162 can be configured as a disc that can rotate relative to the frame 161. The first feeding unit 110, the second feeding unit 120 and the first welding unit 130 are located in different directions of the disc. The disc is provided with a fixing structure for fixing the front cover plate 210. After the first feeding unit 110 fixes the front cover plate 210 and the mica part 220 through the fixing structure, the disc rotates relative to the frame 161 to the second feeding unit 120. After the second feeding unit 120 places the pressure plate 230 in a preset position, the disc continues to rotate to transfer the front cover plate 210 to the first welding unit 130. This ensures that the relative positions of the front cover plate 210, the mica part 220 and the pressure plate 230 remain unchanged during the transfer process, thereby ensuring the welding accuracy of the first welding unit 130 and improving the yield of the cover plate assembly 200.

[0067] Alternatively, the moving part 162 can also be a track, which extends from the first feeding unit 110 to the first welding unit 130. After the front cover plate 210 and mica part 220 are fed onto the track, the track will transport the workpiece to the first welding unit 130. Then, the second feeding unit 120 will directly feed the pressure plate 230 to the preset position of the front cover plate 210. The specific structure of the moving part 162 is not limited in this embodiment. It can be reasonably selected according to actual needs, as long as it can achieve stable transportation of the workpiece.

[0068] See also some of the possible implementation methods. Figure 1 and Figure 3 As shown, the workpiece transfer unit 160 in this embodiment of the application further includes a transfer robotic arm 163, used to transfer the workpiece from the first welding unit 130 to the flattening unit 140, and to transfer the workpiece from the flattening unit 140 to the second welding unit 150.

[0069] It should be noted that the transfer robotic arm 163 is mounted on the frame 161. There can be two transfer robotic arms 163, which are respectively located between the first welding unit 130 and the flattening unit 140 and between the flattening unit 140 and the second welding unit 150. During the process of transferring the workpiece from the second loading unit 120 to the first welding unit 130 and from the first welding unit 130 to the flattening unit 140, the orientation of the workpiece does not need to be changed. Therefore, the first transfer robotic arm 163 only needs to translate the workpiece. However, when transferring from the flattening unit 140 to the second welding unit 150, the second transfer robotic arm 163 is required to flip the workpiece in order to install the inner liner plate 240.

[0070] In addition, the transfer robotic arm 163 has a high degree of freedom, so it can flexibly flip the workpiece and ensure that the workpiece is accurately placed in the position corresponding to the second welding unit 150. This is beneficial to ensuring the assembly accuracy of the cover plate assembly 200 and improving the yield of the cover plate assembly 200.

[0071] Therefore, by setting up a transfer robotic arm 163 to transfer the workpiece, the manpower required for the assembly of the cover plate assembly 200 can be further reduced, and the assembly efficiency of the cover plate assembly 200 can be improved. The specific structure of the transfer robotic arm 163 is not limited in this embodiment of the application, as long as it can flip the workpiece while transferring it.

[0072] See also some of the possible implementation methods. Figure 1 and Figure 3As shown, this embodiment of the application also includes a material unloading unit 170, which includes a material unloading device 171, a material unloading transfer robot 172, and a carrier 173. The material unloading device 171 is used to unload the assembled cover plate assembly 200, the carrier 173 is used to carry the inner liner plate 240, and the material unloading transfer robot 172 is used to transfer the workpiece, the cover plate assembly 200, from the second welding unit 150 to the material unloading device 171 and the inner liner plate 240 from the carrier 173 to the second welding unit 150.

[0073] In a specific implementation, the unloading device 171 can be a conveyor belt. After the unloading transfer robot 172 places the assembled cover plate assembly 200 on the conveyor belt, the conveyor belt unloads the cover plate assembly 200 to the preset position and then transmits it to the next assembly process of the water heater production system, thereby realizing the automatic unloading of the cover plate assembly 200, which is conducive to further saving manpower and improving assembly efficiency.

[0074] Furthermore, the carrier 173 is used to support the inner lining plate 240. The inner lining plate 240 has a plate-like structure, so multiple inner lining plates 240 can be stacked on the carrier 173 for use. After the transfer robotic arm 163 transfers the workpiece to the second welding unit 150, the unloading transfer robot 172 picks up the inner lining plate 240 from the carrier 173 and places it on the front cover plate 210. This eliminates the need for workers to load the inner lining plate multiple times, thereby further saving manpower. At the same time, it avoids direct contact between workers and the second welding unit 150, which is beneficial to protecting the personal safety of workers.

[0075] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of this application also includes a enclosure 180, which encloses the working area 181; a first feeding unit 110 is located outside the working area 181; and a second feeding unit 120, a first welding unit 130, a flattening unit 140, and a second welding unit 150 are all located inside the working area 181.

[0076] In practical implementation, since the pressure head 144 of the flattening unit 140 applies a large pressure when flattening the pressure plate 230, and the first welding unit 130 and the second welding unit 150 generate high temperatures during welding, workers who approach the flattening unit 140, the first welding unit 130, or the second welding unit 150 may be injured due to operational errors, posing a certain safety risk. Therefore, a barrier 180 can be set up to define the working area 181. The first feeding unit 110, the second feeding unit 120, the first welding unit 130, and the flattening unit 140 are all located within the working area 181. The barrier 180 can prevent workers from entering the working area 181, thereby avoiding close contact between workers and the flattening unit 140, the first welding unit 130, or the second welding unit 150. This helps to reduce the safety risks of the cover plate assembly 200 during the assembly process and protect the personal safety of workers.

[0077] In addition, the first loading unit 110 is located outside the work area 181. Workers outside the work area 181 use the first loading unit 110 to load the front cover plate 210 and mica component 220 onto the moving component 162. The moving component 162 then transfers the workpiece to the second loading unit 120 inside the work area 181. Similarly, the carrier 173 can be configured as a rotatable turntable, located outside the work area 181. After workers outside the work area 181 place multiple stacked inner lining plates 240 onto the turntable, the turntable rotates to transfer the inner lining plates 240 into the work area 181, allowing the unloading transfer robot 172 to pick them up. Furthermore, the unloading device 171 can transport the assembled cover plate assembly 200 from inside the work area 181 to outside. Thus, workers can complete the loading and unloading operations of the cover plate assembly 200 without entering the work area 181, further improving the safety of the assembly equipment 100.

[0078] See Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application embodiment also provides a water heater production system, including an assembly equipment 100 for any of the above-mentioned water heater cover plate assemblies 200.

[0079] The structure and working principle of the assembly equipment 100 for the water heater cover assembly 200 have been described in detail in the above embodiments, and will not be repeated here.

[0080] In this embodiment of the application, the assembly equipment 100 of the above-mentioned water heater cover assembly 200 is used to improve the overall assembly efficiency of the water heater production system, save labor costs, and thus save the production cost and yield of the water heater.

[0081] In summary, the assembly equipment 100 for the water heater cover assembly 200 provided in this application embodiment first loads the front cover 210 pre-assembled with the mica component 220 by the first loading unit 110, then transfers the workpiece to the first welding unit 130 by the moving component 162, and the second loading unit 120 loads the pressure plate 230 to the position corresponding to the mica component 220. The first welding unit 130 welds the pressure plate 230 to the front cover 210 to fix the mica component 220. Afterwards, the transfer robotic arm 163 moves the workpiece... The workpiece is transferred to the flattening unit 140, where it is flattened. Another transfer robotic arm 163 flips the workpiece and transfers it to the second welding unit 150. The unloading transfer robot 172 transfers the inner liner 240 from the carrier 173 to the front cover plate 210. The second welding unit 150 welds the inner liner 240 to the front cover plate 210 to obtain the cover plate assembly 200. Finally, the unloading transfer robot 172 transfers the cover plate assembly 200 to the unloading device 171, which unloads the cover plate assembly 200 outside the work area 181. This completes the assembly of the cover plate assembly 200. Therefore, the assembly equipment 100 of this embodiment effectively improves the automation level of the cover plate assembly 200 during the assembly process, which helps save manpower required for assembly, improves the assembly efficiency and accuracy of the cover plate assembly 200, and consequently improves the overall production efficiency and yield of the water heater production system.
