Description

Technical Field

[0001] This application relates to the field of kettle manufacturing technology, and in particular to a kettle manufacturing process with a printed heating plate. Background Technology

[0002] Printed kettles differ from traditional embedded heating elements. Printed heating elements are formed by printing circuit patterns on a ceramic or glass substrate using conductive materials.

[0003] During the production of the heating plate, a suitable substrate material is selected, and precise screen printing technology is used to accurately print conductive paste onto the substrate to form a heating pattern. Multi-layer printing may require drying and sintering to cure the material. Connectors are installed on the heating plate for power interface. Simultaneously, insulating materials are used to ensure the heating plate is safely isolated from other parts of the kettle body.

[0004] In the production and processing of kettles, food-grade stainless steel sheets need to be cut into appropriate sizes according to design requirements. The sheets are then processed and shaped. After assembling and welding the various parts of the kettle and processing the kettle body, the heating plate is fixed to the base using adhesives or metal clamps. The heating plate needs to make good contact with the bottom of the kettle. Therefore, a leak test is required before installing the heating plate. During the leak test, the kettle is filled with clean water and left to stand for half an hour to check its sealing performance. When testing the kettles, operators need to place them one by one in the testing area. Only after the entire batch of kettles has been tested can the next production stage begin, and the next batch of kettles to be tested is placed. This results in low efficiency in testing the kettles' sealing performance, and due to the limited testing area, the placement rate of the kettles is also low. Summary of the Invention

[0005] To improve the processing efficiency of finished kettles, this application provides a kettle processing technology with a printed heating plate.

[0006] The technical solution for manufacturing a kettle with a printed heating plate provided in this application is as follows:

[0007] A manufacturing process for a kettle with a printed heating plate, comprising the following steps:

[0008] S1. Material selection and cutting: Cut food-grade stainless steel sheets into appropriate sizes according to requirements;

[0009] S2. Roll the cut sheet metal into the shape of the kettle body, and then weld it.

[0010] S3. After welding, grind and level the weld to ensure a smooth surface;

[0011] S4. Assembly: Install the spout, lid, base, and other components;

[0012] S5. Conduct batch sampling and sealing tests on the kettles according to the production batch.

[0013] S6. Install the printed heating plate on the base of the kettle;

[0014] S7 integrates with thermostats and other electronic components to control the heating process, enabling automatic switching and temperature control.

[0015] By adopting the above technical solution, the kettle is processed in sequence and then assembled. After the sealing test of the kettle is completed in batches, the printed heating plate is assembled with the kettle. Finally, the thermostat and other electronic components are integrated. During assembly, each assembly component has completed the corresponding quality inspection process, which improves the quality of the kettle. The sealing test of the kettle is carried out in batches, which makes it easy to find kettles with quality problems in time and adjust the production method in time, thereby improving the processing efficiency of finished kettles.

[0016] Optionally, step S6 includes a placement component, a first conveying component located on one side of the placement component, and a water-filling component. The placement component includes a placement frame and multiple placement trays. The placement frame has multiple placement plates spaced apart along its height direction. The placement trays are placed on the placement plates, and the multiple placement trays are spaced apart. The first conveying component is used to convey the kettle body to the placement trays. The first conveying component includes a conveying member and a first lifting member. The first lifting member is located at the bottom of the conveying member and is used to drive the conveying member to rise and fall. The water-filling component is located on one side of the first conveying component and is used to add water to the kettle body on the first conveying component.

[0017] By adopting the above technical solution, when the water bottle is tested for airtightness, the first conveying component conveys the water bottle while the water filling component adds water to the water bottle. After adding water, the first conveying component conveys the water bottle to the placement tray. After one placement tray is completed, the first lifting component is activated. The first lifting component drives the conveying component to rise or fall to place water bottles on other placement trays. The multi-layer placement trays improve the space utilization rate, and the liftable conveying component facilitates the placement of water bottles on the multi-layer placement trays.

[0018] Optionally, the water filling assembly includes a second lifting component and a water filling component. The second lifting component is located on one side of the conveying component and connected to the water filling component. The second lifting component is used to drive the water filling component to rise and fall, and the water filling component is used to add water to the kettle.

[0019] By adopting the above technical solution, the water filling component can move up and down with the second lifting component, reducing the possibility of water splashing due to excessive height difference between the water filling component and the kettle during water filling, thus affecting the kettle's sealing test.

[0020] Optionally, the conveyor is equipped with a signal transmitter, and the placement tray is equipped with a signal receiver at one end near the conveyor. The signal transmitter and the signal receiver are electrically connected.

[0021] By adopting the above technical solution, the signal transmitter and signal receiver can easily align the conveyor with the placement tray, thereby improving the conveying efficiency of the kettle.

[0022] Optionally, the placement tray is provided with adjusting components at both ends near the placement pieces. The adjusting components include adjusting plates, positioning rods, and locking pins. The length of the placement tray is less than the distance between the two symmetrical placement pieces. Both ends of the placement tray near the placement pieces are provided with upwardly inclined extension plates. The adjusting plate is rotatably connected to the end of the extension plate away from the adjusting tray. An adjusting gap is left between the placement tray and the adjusting plate. The positioning rod is rotatably connected to the side of the placement tray adjacent to the adjusting plate. The locking pin is located on the side of the adjusting plate near the positioning rod and is located away from the placement tray. The end of the positioning rod away from the placement tray has a locking groove, and the positioning rod can be located in the locking groove.

[0023] By adopting the above technical solution, when the height of the kettle being tested is different, the positioning rod and the locking post on either side of the placement tray are released, the adjustment plate is retracted, the placement tray is moved above the corresponding placement piece, the adjustment plate is unfolded, and the positioning rod and the locking post are fixed again, so that the placement tray is placed on the corresponding placement piece, thus completing the height adjustment between the placement trays, which is convenient for placing kettles of various heights.

[0024] Optionally, each of the placement trays is provided with a second conveying assembly. The second conveying assembly is used to place the pot body onto the surface of the placement tray. The second conveying assembly includes a first drive, a second drive, a first receiving rod, and a second receiving rod. The first drive and the second drive are spaced apart on the placement tray. One end of the first receiving rod is fixedly connected to the first drive, and the other end is slidably connected to the second drive. One end of the second receiving rod is slidably connected to the first drive, and the other end is fixedly connected to the second drive. The first drive is used to drive the first receiving rod to move, and the second drive is used to drive the second receiving rod to move. The moving directions of the first and second receiving rods are parallel to the conveying direction of the first conveying assembly. The top of each of the first and second receiving rods is provided with a third drive. A moving block is connected to the third drive. The third drive is used to drive the moving block to move along the receiving rod. The moving direction of the moving block is the same as the conveying direction of the first conveying assembly.

[0025] By adopting the above technical solution, when the first conveying component conveys the kettle to the placement tray, the moving block receives the kettle, and the third drive can drive the kettle to move along the first receiving rod and the second receiving rod. The first drive and the second drive can adjust the distance between the first receiving rod and the second receiving rod so that the kettle can be located on the moving block. When the kettle is located on the moving block, the first drive and the second drive can drive the kettle to move along the surface of the placement tray, and the third drive moves the kettle to the placement position on the placement tray. Then, the first drive and the second drive respectively drive the first receiving rod and the second receiving rod to move away from each other, placing the kettle on the placement tray.

[0026] Optionally, the top of the movable block is provided with a receiving platform, which is frustum-shaped. The end of the first receiving rod near the second receiving rod and the end of the second receiving rod near the first receiving rod are both provided with guide plates, and the sides of the guide plates that are close to each other are inclined downwards.

[0027] By adopting the above technical solution, the receiving platform is set in a frustum shape, which makes it easier for the kettle to be removed from the receiving platform, while the guide plate further supports the kettle before it is placed, reducing the drop distance between the kettle and the placement tray, making it easier to gently place the kettle on the placement tray.

[0028] Optionally, a connecting member is provided between the conveyor and the placement tray. The connecting member includes mounting rods symmetrically arranged on both sides of the conveyor and multiple connecting rods arranged between the mounting rods. One end of the mounting rod is rotatably connected to the conveyor. The multiple connecting rods are spaced apart between the mounting rods. Both ends of the connecting rods are connected to the mounting rods respectively. The upper surface of the connecting rod is flush with the upper surface of the receiving platform. The end of the mounting rod near the conveyor is provided with a rotation drive. The rotation drive is used to drive the end of the mounting rod away from the conveyor to move closer to or away from the placement tray.

[0029] By adopting the above technical solution, the rotation drive is started, which drives the mounting rod to rotate, so that the end of the mounting rod away from the conveyor is attached to the placement plate. The connecting rod is flush with the receiving platform. The kettle is conveyed by the conveyor and falls onto the receiving platform along the connecting rod. The receiving platform receives the kettle, reducing the height difference between the conveyor and the receiving platform, making it easier to smoothly transport the kettle onto the receiving platform.

[0030] Optionally, a toggle component is also provided above the conveying component. The toggle component includes a column, a rotating rod, and a toggle drive. There are two columns, which are symmetrically arranged along the conveying direction of the conveying component. The rotating rod is located between the two columns, and both ends of the rotating rod are rotatably connected to the columns. The toggle drive is connected to the rotating rod and is used to drive the rotating rod to rotate. A paddle is provided on the rotating rod and is used to toggle the pot body to the receiving platform.

[0031] By adopting the above technical solution, the toggle drive is activated, which drives the rotating rod to rotate. The rotating rod drives the toggle to rotate, and the toggle toggle the kettle, so that the kettle falls from the connector onto the receiving platform, making it easier to push the kettle from the connector onto the receiving platform.

[0032] Optionally, the surface of the placement tray can be detachably connected to an absorbent layer, which dissolves upon contact with water.

[0033] By adopting the above technical solution, the sealing performance of the kettle can be easily confirmed by observing the water absorption layer, thus improving the efficiency of kettle testing.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By setting up a placement component, a first conveying component, and a water filling component, the detection efficiency of the kettle's sealing test is improved, which improves the overall efficiency when the kettles are tested in batches, facilitates the testing of each batch of kettles, and allows for timely adjustment of the kettle production and processing status according to the batch, thereby improving the processing efficiency of finished kettles.

[0036] 2. By setting a second conveying component, a connector, and a toggle, the connector and toggle facilitate pushing the kettle onto the second conveying component, and then the second conveying component evenly places the kettle on the placement tray, making it easy to place the kettle on the placement tray.
