TECHNICAL FIELD

[0001] The utility model relates to the technical field of water heater assembly equipment, and particularly relates to a kind of assembly equipment of inner container and shell of water heater. BACKGROUND

[0002] In the prior art, the inner machine production of water heater usually involves independent manufacturing of inner machine shell and inner container, and then the inner container is accurately placed in the shell through a hoisting process, and finally foaming treatment is carried out to complete the assembly. However, in this process, especially in the hoisting link, an operator often needs to be arranged at the hoisting station to manually monitor and adjust the docking position between the inner container and the shell. This method highly depends on the experience and subjective judgment of the operator, especially in the precise positioning in three-dimensional space.

[0003] Due to the large uncertainty of this method depending on personal experience, it is easy to cause the inner container to collide with the shell during placement, thereby causing damage to the parallel flow assembly on the inner container. This condition not only reduces the quality of assembly, but also may affect the subsequent heating performance of the water heater, leading to problems such as efficiency reduction.

[0016] Beneficial effects:

[0017] The present invention provides an assembly device for the inner tank and shell of a water heater, comprising a mounting frame, a lifting component, and an imaging component. The mounting frame is positioned on an installation reference and includes an assembly space. The lifting component is movably mounted on the mounting frame, located above the assembly station, with at least a portion within the assembly space. The lifting component is used to grasp the inner tank, lift it, and move it above the shell at the assembly station, thereby assembling the inner tank into the shell. The imaging component is mounted on the mounting frame and located within the assembly space. It acquires data on the relative position between the inner tank and the shell when the lifting component transports the inner tank to a preset position above the shell and is in a suspended state. The imaging component is connected to the lifting component and controls the movement of the lifting component based on the acquired data, ensuring that the inner tank is coaxially aligned with the shell when suspended above it, and thus also coaxially aligned when installed in the shell. Therefore, by setting up the imaging component, the positional data of the inner liner relative to the shell can be accurately acquired, thus determining whether the inner liner and shell are coaxially aligned. Based on this determination, the movement of the lifting component can be controlled to adjust the position of the inner liner relative to the shell, ensuring that the inner liner and shell are coaxially aligned when the inner liner descends. This precise positioning and adjustment mechanism effectively avoids collisions caused by positional deviations, significantly improving assembly accuracy and consistency, thereby enhancing the overall quality of the product. Simultaneously, the application of the imaging component automates the assembly process, reducing manual monitoring and adjustment work by operators at the lifting station. This not only reduces the uncertainty caused by human factors but also significantly reduces labor intensity and shortens assembly time, thus significantly improving production efficiency. Furthermore, the lifting component is movably mounted on the mounting frame, further enhancing its flexibility and allowing it to adapt to inner liners and shells of different sizes. Through the lifting component, the inner liner can be precisely gripped, lifted, moved, and placed, ensuring that the inner liner is accurately assembled into the shell. This design not only improves operational flexibility and adaptability but also ensures consistency and stability in each assembly. This assembly equipment can effectively solve the technical problem in the existing technology that requires manual monitoring and adjustment of the docking position between the inner tank and the shell when placing the inner tank of the water heater inside the shell.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] Please see Figures 1 to 6According to an embodiment of the present invention, an assembly device for the inner tank and shell of a water heater is provided, comprising: a mounting frame 1, a lifting component 2, and an imaging component 3. The mounting frame 1 has an assembly space 10, and the assembly space 10 has an assembly station. The lifting component 2 is movably mounted on the mounting frame 1 and is located above the assembly station. The lifting component 2 is used to grasp the inner tank 100 and assemble the inner tank 100 into the shell 200 located at the assembly station. The imaging component 3 is mounted on the mounting frame 1 and is located within the assembly space 10. The imaging component 3 is used to acquire data on the relative position of the inner tank 100 and the shell 200 when the inner tank 100 is suspended at a preset position above the shell 200. The imaging component 3 is connected to the lifting component 2 and controls the movement of the lifting component 2 according to the acquired results, so that the inner tank 100 and the shell 200 are coaxially arranged.

[0028] As can be seen, the assembly equipment for the inner tank and shell of the water heater provided by this utility model includes a mounting frame 1, a lifting component 2, and an imaging component 3. The mounting frame 1 is set on an installation reference and has an assembly space 10 within it. The lifting component 2 is movably mounted on the mounting frame 1, located above the assembly station, and at least a portion of the lifting component 2 is located within the assembly space 10. The lifting component 2 is used to grasp the inner tank 100, lift it, and move it above the shell 200 located at the assembly station, thereby assembling the inner tank 100 into the shell 200. The imaging component is mounted on the mounting frame 1 and located within the assembly space. The imaging component 3 is used to acquire data on the relative position between the inner tank 100 and the shell 200 when the lifting component 2 transports the inner tank 100 to a preset position above the shell 200 and is in a suspended state. The imaging component 3 is connected to the hoisting component 2. The imaging component 3 controls the movement of the hoisting component 2 based on the acquired structural data, ensuring that the inner liner 100 is coaxially aligned with the shell 200 when suspended above it. This ensures that the inner liner 100 is also coaxially aligned when installed on the shell 200. Therefore, by using the imaging component 3, the position data of the inner liner 100 relative to the shell 200 can be accurately acquired, thus determining whether the inner liner 100 is coaxial with the shell 200. Based on this determination, the hoisting component 2 can be controlled to adjust the position of the inner liner 100 relative to the shell 200, ensuring that the inner liner 100 is coaxial with the shell 200 when it descends. This precise positioning and adjustment mechanism effectively avoids collisions caused by positional deviations, significantly improving assembly accuracy and consistency, and thus enhancing the overall quality of the product. Simultaneously, the application of the imaging component 3 automates the assembly process, reducing the manual monitoring and adjustment work required by operators at the hoisting station. This not only reduces the uncertainty caused by human factors but also significantly reduces labor intensity and shortens assembly time, thereby significantly improving production efficiency. Furthermore, the lifting component 2 is movably mounted on the mounting frame 1, further enhancing its flexibility and enabling it to adapt to inner tanks 100 and shells 200 of different sizes. Through the lifting component 2, the inner tank 100 can be precisely gripped, lifted, moved, and placed, ensuring that the inner tank 100 can be accurately assembled into the shell 200. This design not only improves operational flexibility and adaptability but also ensures consistency and stability in each assembly. This assembly equipment effectively solves the technical problem in existing technologies where the docking position between the inner tank and the shell needs to be manually monitored and adjusted when placing the inner tank of a water heater into the shell.

[0029] Furthermore, when the housing 200 is located at the assembly station, the imaging component 3 is located above the housing 200. With this structural arrangement, when the housing 200 is transported into the assembly space 10, the imaging component 3 can avoid the housing 200 and can also effectively acquire the relative position data between the inner liner 100 and the housing 200 when the inner liner 100 is suspended in a preset position.

[0030] Specifically, the assembly equipment also includes a control component, which is connected to both the imaging component 3 and the hoisting component 2. The control component receives data on the relative position of the inner liner 100 and the outer shell 200 from the imaging component 3, determines whether the inner liner 100 and the outer shell 200 are coaxial based on the received data, and controls the hoisting component 2 to move accordingly. This structural arrangement allows the control component to accurately detect the relative position of the inner liner 100 and the outer shell 200 when suspended in a preset position. Based on the actual detection results, the control component can adjust the movement of the hoisting component 2 in real time to keep the inner liner 100 suspended in a centered position relative to the outer shell 200, thus ensuring that the inner liner 100 and the outer shell 200 remain coaxial at all times. This automated adjustment mechanism effectively avoids errors from manual adjustments, improving the accuracy and consistency of the assembly.

[0031] Furthermore, the imaging component 3 acquires the relative position data between the inner liner 100 and the outer shell 200, and feeds this data back to the control component in the form of an image. The control component uses an image processing algorithm to accurately calculate the specific position of the inner liner 100 relative to the outer shell 200. Based on the calculation results, the control component determines whether it is necessary to control the lifting component 2 to move the inner liner 100 along the X-axis and / or Y-axis, thereby adjusting the position of the inner liner 100 relative to the outer shell 200 to ensure that the suspended position of the inner liner 100 is centered with the outer shell 200, that is, the adjusted inner liner 100 and the outer shell 200 are coaxially set.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the imaging component 3 includes a first camera 31 and a second camera 32. The first camera 31 and the second camera 32 are mounted on the mounting bracket 1. The first camera 31 and the second camera 32 are positioned at different preset angles towards the docking area between the inner liner 100 and the outer shell 200. When the inner liner 100 is suspended above the outer shell 200 at a preset position via the suspending component 2, the first camera 31 and the second camera 32 respectively acquire image data of the relative positions of the inner liner 100 and the outer shell 200. With this structural arrangement, the first camera 31 and the second camera 32 capture images of the inner liner 100 and the outer shell 200 from different angles, thus providing data from multiple perspectives. This multi-view design can more comprehensively capture the relative positional relationship between the two, ensuring more accurate information acquisition. Furthermore, shooting with cameras at different angles can effectively cover the blind spots that may exist with a single camera, avoiding measurement errors caused by a single perspective.

[0033] The docking area between the inner liner 100 and the shell 200 can be understood as the area between the lower end of the inner liner 100 and the upper end of the shell 200 when the inner liner 100 is suspended in the predetermined position. This is the key position where the inner liner 100 is about to enter the shell.

[0034] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting frame 1 includes: a rectangular frame 11, four support rods 12, a first crossbeam 13, and a second crossbeam 14. The rectangular frame 11 is positioned above the assembly station, and the lifting component 2 is movably mounted on the rectangular frame 11. Each support rod 12 is mounted on an installation reference, and each support rod 12 extends vertically. Each support rod 12 is spaced around the edge of the rectangular frame 11, and the four support rods 12 are located at the four corners of the rectangular frame 11. The four support rods 12 and the rectangular frame 11 form an assembly. Space 10; the two ends of the first crossbeam 13 and the two ends of the second crossbeam 14 are respectively connected to two adjacent support rods 12. The first crossbeam 13 extends along the length of the rectangular frame 11, and the second crossbeam 14 extends along the width of the rectangular frame 11, with the second crossbeam 14 located on the side of the rectangular frame 11 away from the lifting component 2 that grips the inner liner 100. Both the first crossbeam 13 and the second crossbeam 14 are located below the rectangular frame 11, and the first camera 31 and the second camera 32 are respectively mounted on the first crossbeam 13 and the second crossbeam 14. With this structural arrangement, by setting the first crossbeam 13 and the second crossbeam 14, the first camera 31 and the second camera 32 can be placed at a 90-degree angle, ensuring that the docking area between the inner liner 100 and the shell 200 can be photographed from both the X-axis and Y-axis directions. This layout ensures that image data is acquired from different angles, providing a more comprehensive view, thereby effectively eliminating blind spots that may exist from a single perspective, and thus improving the accuracy of measurement.

[0035] Furthermore, one end of the first crossbeam 13 and one end of the second crossbeam 14 are located on the same support rod 12, and the first crossbeam 13 and the second crossbeam 14 are arranged perpendicularly. Both the first crossbeam 13 and the second crossbeam 14 are located above the housing 200.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the lifting component 2 includes a cable tray 21 and a lifting assembly 22. The cable tray 21 is movably mounted on the rectangular frame 11 along its width direction and extends along its length direction. The lifting assembly 22 is movably mounted on the cable tray 21 and is used to lift or release the inner liner 100. With this structural arrangement, the cable tray 21 can move freely along the width direction of the rectangular frame 11, giving the lifting component 2 high flexibility throughout the width of the assembly space 10. Combined with the design of the cable tray 21 extending along the length direction of the rectangular frame 11, this ensures that the lifting component 2 can flexibly reach any position within the entire assembly space 10. Through the coordinated work of the cable tray 21 and the lifting assembly 22, the inner liner 100 can move precisely along the X-axis (width direction), Y-axis (length direction), and Z-axis (vertical direction), ensuring coaxial alignment between the inner liner 100 and the shell 200, thereby achieving accurate lifting, movement, and placement of the inner liner 100.

[0037] Wherein, the width direction of the rectangular frame 11 is as follows Figure 6 The direction indicated by C in the middle.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the lifting assembly 22 includes a movable component, a lifting component 221, and a gripping component 222. The movable component is movably mounted on the cable tray 21 along its extension direction. The lifting component 221 is mounted on the movable component, with the free end of its lifting rope 2211 facing the assembly station, and the lifting rope 2211 is vertically adjustable relative to the assembly station. The gripping component 222 is mounted on the free end of the lifting rope 2211 and is used to grip or release the inner liner 100. With this structural arrangement, the movable component allows the lifting component 221 to reciprocate along the extension direction of the cable tray 21, ensuring that the inner liner 100 can be flexibly positioned in the Y-axis direction. Furthermore, the lifting component 221 enables precise lifting and lowering in the Z-axis direction, ensuring that the inner liner 100 can be accurately lifted or lowered.

[0039] The Y-axis refers to the length of the rectangular frame 11, the X-axis refers to the width of the rectangular frame 11, and the Z-axis refers to the height of the mounting bracket 1.

[0040] In the first embodiment of the gripping component 222 provided by this utility model, the gripping component 222 includes an electromagnet, which grips or releases the inner liner 100 by switching the electromagnet on and off. With this structural arrangement, the electromagnet's on / off operation is rapid and easy to control, enabling quick response to commands issued by the control system and achieving instant gripping or release. Compared to traditional mechanical gripping devices, the electromagnet reduces complex mechanical structures, simplifies the operation process, and lowers maintenance costs. Furthermore, by precisely controlling the current intensity of the electromagnet, the magnetic force can be adjusted to ensure that the inner liner 100 is firmly gripped without causing damage. In addition, because the electromagnet is simple and reliable to operate, the entire assembly equipment can operate continuously without manual intervention, further improving the overall efficiency of the production line. Moreover, the rapid gripping and release operation helps to shorten the time of each assembly cycle, thereby improving overall productivity.

[0041] In the second embodiment of the gripping member 222 provided by this utility model, as shown in the example Figure 3 As shown, a hanging engagement part is provided at the top of the inner liner 100, and the gripping member 222 is a hanging part, which is connected to the hanging engagement part to grip the inner liner 100; or the inner liner 100 is released by separating the hanging part from the hanging engagement part.

[0042] The first hook is the mounting and the second hook is the gripping part 222. The first hook and the second hook are used for mounting or detaching.

[0043] Specifically, such as Figure 4 and Figure 5 As shown, the assembly equipment also includes: guide rails 4, of which there are two, both extending along the width direction of the rectangular frame 11, and the two guide rails 4 are spaced apart along the length direction of the rectangular frame 11; the two ends of the cable tray 21 are movably mounted on corresponding guide rails 4 along the extension direction of the guide rails 4. This structural arrangement, by setting the guide rails 4, provides a basis for the smooth movement of the cable tray 21, ensuring that the cable tray 21 can achieve precise positioning and movement within the width range of the entire assembly space 10.

[0044] Furthermore, such as Figure 6As shown, the rectangular frame 11 includes: a third crossbeam 111, a first longitudinal beam 112, a fourth crossbeam 113, and a second longitudinal beam 114 connected end to end. The third crossbeam 111 and the fourth crossbeam 113 extend along the length of the rectangular frame 11, while the first longitudinal beam 112 and the second longitudinal beam 114 extend along the width of the rectangular frame 11. Two guide rails 4 are respectively installed at the top ends of the first longitudinal beam 112 and the second longitudinal beam 114.

[0045] Furthermore, such as Figure 5 As shown, the assembly equipment also includes two movable blocks 7, each corresponding to one of the two guide rails 4. Each movable block 7 has a guide groove at its bottom that matches the guide rail 4. The guide groove extends along the extension direction of the guide rail 4 and forms a guiding engagement with the corresponding guide rail 4. Thus, each movable block 7 can move along the extension direction of its corresponding guide rail 4 via the guide groove. The two ends of the cable tray 21 are respectively mounted on the corresponding movable blocks 7, allowing the cable tray 21 to move via the two movable blocks 7.

[0046] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the assembly equipment further includes: a first double-speed chain conveyor 5 and a second double-speed chain conveyor 6. The first double-speed chain conveyor 5 extends along a first preset trajectory, and at least a portion of the first double-speed chain conveyor 5 is located within the assembly space 10. An assembly station is provided on the first double-speed chain conveyor 5 for conveying the housing 200 to be assembled and the assembled housing 200. The second double-speed chain conveyor 6 extends along a second preset trajectory, and one end of the second double-speed chain conveyor 6 is located within the assembly space 10. The first double-speed chain conveyor 5 and the second double-speed chain conveyor 6... The assembly line is configured with six intervals, and the extension direction of the first double-speed chain conveyor 5 and the extension direction of the second double-speed chain conveyor 6 form a preset angle, which is greater than 0° and less than 180°. The second double-speed chain conveyor 6 is used to convey the inner liner 100 toward the assembly space 10. The second double-speed chain conveyor 6 has a gripping station located within the assembly space 10. When an inner liner 100 on the second double-speed chain conveyor 6 is conveyed to the gripping station, the lifting component 2 grips the inner liner 100 located at the gripping station. This structural configuration, through the combined use of the first double-speed chain conveyor 5 and the second double-speed chain conveyor 6, achieves efficient conveying and positioning of the shell 200 and the inner liner 100, improving the operational flexibility of the entire assembly process. Furthermore, by having two double-speed chain conveyors respectively responsible for conveying the shell 200 and the inner liner 100, it ensures that materials are accurately delivered to the designated positions at different stages. In addition, the precise positioning and automated control system of the double-speed chain ensures that the shell 200 and the inner liner 100 can dock at the correct time and position, reducing errors in manual operation.

[0047] Furthermore, the extension direction of the first double-speed chain 5 is perpendicular to the extension direction of the second double-speed chain 6. The extension direction of the first double-speed chain 5 is consistent with the conveying direction of the conveying housing 200, while the extension direction of the second double-speed chain 6 is consistent with the conveying direction of the conveying inner liner 100.

[0048] Furthermore, the second speed chain body 6 and the second crossbeam 14 are spaced apart along the length of the rectangular frame 11, that is, the second speed chain body 6 and the second crossbeam 14 are arranged opposite to each other.

[0049] Preferably, the first speed-multiplying chain body 5 extends along the width direction of the rectangular frame 11, and the second speed-multiplying chain body 6 extends along the length direction of the rectangular frame 11.

[0050] Specifically, the assembly equipment further includes: a first blocking component and a second blocking component, which are spaced apart on the first double-speed chain conveyor 5 along its extension direction; the first blocking component is located upstream of the assembly station, and the second blocking component is located downstream of the assembly station; the first and second blocking components are used to block or avoid the housing 200 located on the first double-speed chain conveyor 5. With this structural arrangement, by setting the first and second blocking components, the housing 200 can be accurately positioned when it arrives at the assembly station, while simultaneously blocking other housings 200 located upstream, preventing them from entering the assembly station prematurely. This design ensures that each housing 200 is accurately positioned at the correct time and location, providing convenience and support for subsequent assembly processes.

[0051] Specifically, the assembly equipment also includes a third blocking component and a fourth blocking component, which are spaced apart along the extension direction of the second double-speed chain conveyor 6. The third blocking component is located upstream of the gripping station, and the fourth blocking component is located downstream of the gripping station. The third and fourth blocking components are used to block or avoid the inner liner 100 located on the second double-speed chain conveyor 6. With this structural arrangement, by setting the third and fourth blocking components, the inner liner 100 can be accurately positioned when it enters the gripping station, while simultaneously blocking other inner liners 100 located upstream, thereby preventing collisions between the inner liner 100 located at the gripping station and other inner liners 100 upstream. This arrangement ensures that each inner liner 100 is accurately positioned at the correct time and location, providing convenience and support for subsequent assembly processes.

[0052] The assembly process of the equipment is as follows:

[0053] Step 1: The shell 200 and the inner liner 100 move along the conveying direction of their respective double-speed conveyor belts. When the shell 200 moves to the assembly station, both the first and second blocking components are in the first blocking state to position the shell 200 at the assembly station. Simultaneously, when the inner liner 100 moves to the gripping station, both the third and fourth blocking components are in the second blocking state to position the inner liner 100 at the gripping station.

[0054] Step 2: When the inner liner 100 is located at the gripping station, the lifting component 2 moves towards the gripping station. When the gripping part 222 of the lifting component 2 is above the inner liner 100, the lifting rope 2211 descends to allow the gripping part 222 to grip the inner liner 100. After gripping, the inner liner 100 is raised by the lifting rope 2211. When it reaches the designated height, the lifting component 2 moves the inner liner 100 to a preset position. At this time, the inner liner 100 is suspended above the shell 200.

[0055] Step 3: When the inner liner 100 is suspended above the outer shell 200, the first camera 31 and the second camera 32 capture images of the relative positions of the inner liner 100 and the outer shell 200, and feed the captured images back to the control unit. The control unit processes the captured images and accurately calculates the positional deviation and distance difference between the center lines of the outer shell 200 and the inner liner 100. Based on these calculation results, the control unit issues a command to adjust the movement of the lifting component 2 to correct the position of the inner liner 100, ensuring that it is centered in both the X and Y axes. Once the inner liner 100 is centered in both directions, the control unit outputs a pass signal, instructing the lifting component 2 to perform the final operation, smoothly and accurately inserting the inner liner 100 into the outer shell 200.

[0056] Step 4: After the inner liner 100 is successfully assembled, the lifting component 2 will release the inner liner 100, securing it firmly inside the housing 200. The lifting component 2 will then retract away from the housing 200, preparing for the next operation. Simultaneously, the first and second blocking components switch to a first clearance state, ensuring that the next housing 200 can smoothly enter the assembly station and that the assembled housing 200 can smoothly leave the assembly station. Furthermore, the third and fourth blocking components also switch to a second clearance state, allowing the next inner liner 100 to move smoothly to the gripping station, ensuring the smooth progress of the next gripping cycle.
