Description

Technical Field

[0001] This invention relates to the field of component assembly technology, and more specifically to an assembly line and assembly method for rotor-driven electronic products that can be used in fields such as vehicles and thermal management systems. Background Technology

[0002] Rotors are widely used in various valves, pumps, and other components. A magnetized rotor can rotate under the magnetic field generated by the stator, and its magnetic properties determine whether it can perform its function. Magnetizing the rotor is a crucial step in its manufacturing process, but due to various reasons, rotors may fail to be magnetized. Therefore, it is necessary to perform magnetization testing on the rotor after the magnetization process.

[0003] In the field of rotor assembly, rotors have many components and involve numerous assembly processes. Setting up a separate magnetization and testing station on the production line requires additional space, personnel, and equipment, increasing manufacturing costs and reducing production cycle time, making it difficult to improve the overall production efficiency of the assembly line. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly line for electronic products with a rotor, which aims to reduce manufacturing costs and improve the production efficiency of the assembly line.

[0005] This invention provides an assembly line for electronic products with rotors, including a magnetization station and a testing station. The testing station has a rotor receiving seat, a first testing module, and a second testing module. The rotor receiving seat has a rotor receiving position and a first rotating shaft, which can rotate under force. The first testing module can be used for first target operation testing, which includes magnetization testing. The first testing module has a first magnetic rotor, and there is a set distance d between the first magnetic rotor and the rotor receiving position. The set distance d is within the magnetic field coverage range of the magnetized target rotor. The first magnetic rotor can rotate in response to the rotation of the rotor to be worked. The second testing module can be used for second target operation testing, which is not magnetization testing.

[0006] In this way, at the same workstation, namely the inspection workstation, the rotor to be operated can be simultaneously inspected for the first target operation and the second target operation on the rotor to be operated housing. The first target operation inspection includes magnetization inspection, and the second target operation inspection is non-magnetization inspection. Magnetization inspection and non-magnetization inspection can be completed in the same process cycle, which not only ensures that the non-magnetized rotor is identified, but also improves the production efficiency of the entire assembly line and reduces manufacturing costs.

[0007] This application also provides a method for assembling an electronic product with a rotor, comprising the following steps: placing the rotor to be operated on a rotor receiving seat, and adjusting the position of the first magnetic rotor of the first detection module such that the distance between the first magnetic rotor and the rotor receiving position of the rotor receiving seat is within the magnetic field coverage range of the magnetized target rotor.

[0008] The first target operation test is performed on the rotor to be operated. The rotor to be operated is rotated. If the first magnetic rotor does not rotate, it is determined that the rotor to be operated is not magnetized; if the first magnetic rotor rotates, it is determined that the rotor to be operated is magnetized.

[0009] Perform a second target inspection on the rotor to be operated;

[0010] The first and second target job inspections are completed at the same workstation.

[0011] The assembly method using the above technical solution can achieve both the first and second target operation inspections at one workstation, effectively improving rotor assembly efficiency and reducing rotor assembly costs. Attached Figure Description

Detailed Implementation

[0020] To make the objectives and technical solutions of this invention easier to understand, the following detailed description of the invention is provided in conjunction with specific embodiments.

[0021] Rotors are widely used in mechanical engineering. Most rotors operate on the principle of relying on their own magnetism and working under the influence of a magnetic or electric field. The main applications of rotors are in various pumps and valves, with water pumps being a typical example. Currently, the mainstream pumping power for water pumps relies on the stator driving the rotor to rotate, thereby achieving water pumping. The interaction between the stator and rotor is mainly through magnetic fields, and the rotor's magnetism plays a crucial role in the integrity of its functional application.

[0022] Pumps, valves, and other application components involve numerous parts that mate with the rotor, making rotor assembly quite complex. Furthermore, due to the large number of mate components, there are many process nodes in the assembly process, requiring numerous performance tests. This often results in numerous assembly line stations for rotors, longer production times, and higher manufacturing costs.

[0023] This application provides an assembly line for electronic products with a rotor, such as... Figure 1As shown, it includes a magnetization station and a detection station. The detection station has a rotor receiving seat 8, a first detection module 100, and a second detection module. The rotor receiving seat 8 has a rotor receiving position 82 and a first rotating shaft 81. The first rotating shaft 81 can rotate under force. The first detection module 100 can be used for first target operation detection, which includes magnetization detection. The first detection module 100 has a first magnetic rotor 1. There is a set distance d between the first magnetic rotor 1 and the rotor receiving position 82. The set distance d is within the magnetic field coverage range of the magnetized target operation rotor. The first magnetic rotor 1 can rotate in response to the rotation of the rotor to be operated. The second detection module can be used for second target operation detection, which is a non-magnetization detection. In the assembly line solution for electronic products with rotors provided in this application, the first target operation inspection and the second target operation inspection are combined into one inspection station, and a rotor receiving seat 8 is set up. The rotor 2 to be operated can simultaneously perform the first target operation inspection and the second target operation inspection on the rotor receiving seat 8. The first target operation inspection includes magnetization inspection, and the second target operation inspection is non-magnetization inspection. This reduces the space, personnel and production cycle time occupied by the separate magnetization inspection process, improves the assembly line efficiency and reduces the production cost.

[0024] In this embodiment, the magnetized target working rotor specifically includes a working rotor that has been clearly magnetized to a qualified level. A set distance d exists between the first magnetic rotor 1 and the rotor receiving position 82. Specifically, the set distance d is understood as the distance between the edge of the first magnetic rotor 1 and the edge of the rotor receiving position 82. Figure 3 As shown. Specifically applied in the assembly line of electronic products with rotors, during the pre-production calibration of the equipment, the qualified magnetized target rotor is placed in the rotor receiving position 82, and the magnetized target rotor is rotated. The first magnetic rotor 1 moves closer to the rotor receiving position 82. When the first magnetic rotor 1 is just able to rotate, the distance between the first magnetic rotor 1 and the rotor receiving position 82 at this time is m. It can be understood that in this embodiment, the distance d is set to ≤ m.

[0025] In a specific embodiment, such as Figure 2 As shown, the second target operation inspection includes flatness inspection; the assembly line for electronic products with rotors includes an impeller assembly station, which is located before the magnetization station and before the inspection station. In one embodiment, depending on the needs of the assembly line, the impeller assembly station may also be located after the magnetization station.

[0026] like Figure 3-4As shown, the second detection module has a sensing detection component 200. The sensing detection component 200 of the impeller flatness detection device is located above the rotor receiving seat 8. The sensing detection component 200 can detect the impeller flatness and includes a displacement detection sensor or camera. The first detection module 100 is located on the side of the rotor receiving seat 8. A magnetic field generator 7 is also provided at the detection station. The magnetic field generator 7 can generate a first rotating magnetic field. The rotor receiving seat 8 is located within the first rotating magnetic field generated by the magnetic field generator 7. The magnetized rotor can rotate under the action of the magnetic field generator. At this time, the first rotating shaft 81 can rotate relative to the magnetic field generator 7, that is, the magnetized rotor fitted on the first rotating shaft can rotate relative to the magnetic field generator; the first magnetic rotor 1 can rotate relative to the first rotating shaft 81, that is, the first magnetic rotor can rotate following the magnetized rotor (or the first rotating shaft). The second target operation inspection includes impeller flatness inspection. In this inspection, the rotor to be inspected needs to rotate. The receiving seat 8 is located within the first rotating magnetic field generated by the magnetic field generator 7. The first inspection module 100 is positioned to the side of the receiving seat 8, effectively utilizing the space of the impeller flatness inspection station and improving production line space utilization. The first magnetic rotor 1 is used to detect whether the rotor to be inspected on the receiving seat 8 is magnetized. Simultaneously, the existing magnetic field generator 7 at the impeller flatness inspection station is utilized, reducing the need for additional energy-powered equipment. This efficient use of existing equipment at the impeller flatness inspection station requires only a small increase in the number of inspection components in the first inspection module 100, achieving the assembly objective with minimal investment in inspection equipment and further reducing production line equipment costs.

[0027] The first shaft end of the first rotating shaft 81 is connected to the rotor receiving position 82, and the first rotating shaft 81 can rotate relative to the rotor receiving position 82; the magnetic field generator 7 includes a second magnetic rotor 71 and a motor 72, and the motor 72 can drive the second magnetic rotor 71 to rotate.

[0028] In one embodiment, the sensing and detection component 200 includes a displacement detection sensor or camera. The sensing and detection component detects the flatness of the impeller surface by displacement detection, for example. In this way, the second magnetic rotor 71 is driven to rotate by the motor 72, thereby using the first rotating magnetic field generated by the second magnetic rotor 72 to drive the rotor to be operated to rotate. This can reduce the axial movement problem caused by the first rotating shaft 81 being connected to the motor for rotation and improve the accuracy of impeller flatness detection.

[0029] The inspection station is also equipped with a mounting plate 13, which has a first end and a second end opposite to each other. A second rotating shaft 73 is connected to the first end of the mounting plate 13, and a second magnetic rotor 71 is connected to the second rotating shaft 73. A motor 72 is mounted on the second end of the mounting plate 13 and can drive the second rotating shaft 73. The rotation of the second rotating shaft 73 drives the second magnetic rotor 71 to rotate. A rotor receiving position 82 is provided on the mounting plate 13, and the rotor receiving position 82 is located on the same side of the second rotating shaft 73 as the mounting plate 73. In this way, the space of the inspection station can be effectively utilized, the space occupied by the motor on the first end of the mounting plate can be reduced, and the space utilization rate of the production line can be improved.

[0030] In the specific implementation, the name of the inspection station can be an assembly station, rotor inspection station, rotor magnetization inspection, flatness test, etc. The name of the inspection station is not limited, but its function should at least have rotor magnetization inspection function and another function related to rotor and / or rotor application assembly.

[0031] like Figure 6 As shown, in this embodiment, the first detection module 100 includes a first magnetic rotor 1 and an automatic detection module 4. The automatic detection module 4 can detect the rotation signal of the first magnetic rotor 1.

[0032] Specifically, in this embodiment, a second magnetic rotor 71 is provided, and rotating the second magnetic rotor 71 generates a first rotating magnetic field. The first magnetic rotor 1 is placed outside the first rotating magnetic field, and there is a set distance d between the first magnetic rotor 1 and the rotor receiving position 82. The set distance d is within the magnetic field coverage range of the magnetized target rotor, thus ensuring that when the target rotor 2 is rotating on the rotor receiving position 82, the first magnetic rotor 1 can be affected by the magnetic field of the target rotor 2 and thus rotate. Whether the target rotor 2 is magnetized is determined by whether the first magnetic rotor 1 rotates. If the first magnetic rotor 1 rotates, it indicates that the target rotor 2 is magnetized. Specifically, after the target rotor 2 is magnetized, it will rotate under the action of the first rotating magnetic field. The rotation of the magnetized target rotor generates a second rotating magnetic field, which interacts with the first magnetic rotor 1, thereby driving the first magnetic rotor 1 to rotate. If the first magnetic rotor 1 does not rotate, it is determined that the rotor 2 to be operated on is not magnetized. Specifically, if the rotor 2 to be operated on is not magnetized, it will not rotate within the first rotating magnetic field, and therefore will not generate the second rotating magnetic field. Consequently, the rotor 2 will not interact with the first magnetic rotor 1, and thus the first magnetic rotor 1 will not rotate. Alternatively, if the rotor 2 to be operated on is not magnetized or is not properly magnetized, it will rotate within the first rotating magnetic field, but it will not generate a rotating magnetic field, or the intensity of the rotating magnetic field it generates will be insufficient to cause the first magnetic rotor 1 to rotate within a set distance d. In this case, the first magnetic rotor 1 will also not rotate, thus determining that the rotor 2 to be operated on is not magnetized. The rotor magnetization detection method in this embodiment uses the first magnetic rotor 1 and the second magnetic rotor 71 to test whether the rotor 2 to be operated on is magnetized. The detection method is simple and has low testing costs.

[0033] The automatic detection module 4 includes a sensor 5 and a light signal generator 6. The assembly line also has a main unit, which is communicatively connected to the sensor 5. The sensor 5 has a blade portion 51 and at least one groove 52; the groove 52 is recessed into the axis of the sensor 5. The sensor 5 is coaxially connected to the first magnetic rotor 1. The light signal emitted by the light signal generator 6 can illuminate either the blade portion 51 or the groove 52. When the first magnetic rotor 1 is rotating, the light signal generator 6 emits light signals to alternately illuminate the blade portion 51 and the groove 52. When the first magnetic rotor 1 is stationary, the light signal generator 6 emits light signals to continuously illuminate either the blade portion 51 or the groove 52. The main unit determines whether the rotor 2 to be operated is magnetized based on the light signal received by the sensor 5. Figure 2 Unless otherwise indicated, the host computer may be any computer with data processing capabilities known to those skilled in the art. The host computer may be a processor in an assembly line or a processor unique to a testing station.

[0034] It should be understood that the host can be the control chip for the entire assembly line, or it can be the control chip for each individual product.

[0035] When the first magnetic rotor 1 rotates, it drives the induction plate 5 to rotate. The groove 51 of the induction plate 5 rotates with it, and the light signal shines on the impeller part 52-groove 51-impeller part 52, and so on, alternating. The light signal received by the induction plate 5 changes, and the host computer communicates with the induction plate 5, so the host computer determines whether the rotor assembly is magnetized. By using the rotation signal to detect whether the rotor 2 to be operated is magnetized, the automatic detection module 4 has a simple structure and a simple working principle, so the equipment investment can achieve the detection purpose with less investment, and the equipment maintenance is also simple, with low equipment investment and maintenance costs.

[0036] The first detection module 100 also includes a fixed base 9, a cross arm 10, a bearing 11, and a connecting shaft 12. One end of the cross arm 10 is fixedly connected to the fixed base 9, and the other end of the cross arm 10 is sleeved on the outside of the bearing 11. The connecting shaft 12 is sleeved on the inner shaft of the bearing 11. The first end of the connecting shaft 12 along its axis is connected to the first magnetic rotor 1, and the second end of the connecting shaft 12 along its axis is connected to the sensing plate 5. A light signal generator 6 is fixedly connected to the side wall of the cross arm 10. The signal generator 6 has a light-emitting end 61, which is located below the sensing plate 5 along the axis of the connecting shaft 12. Specifically, the first magnetic rotor 1 is sleeved on the outside of a miniature clamp 14 at the first end of the connecting shaft 12 along its axis, and the miniature clamp 14 is fixedly connected to the first end of the connecting shaft 12. In this way, the first magnetic rotor 1 can be different magnetic rotors to test different rotors to be tested, increasing the adaptability of the detection device to different testing conditions.

[0037] The rotor 2 to be operated is fitted onto the rotor receiving seat 8. The motor 72 is energized, driving the second rotating shaft 73 to rotate. The second magnetic rotor 71 rotates, generating a first rotating magnetic field. If the rotor 2 to be operated is magnetized, the first magnetic rotor 1 will be driven to rotate by the second rotating magnetic field generated by the rotor 2. The connecting shaft 12 rotates with the first magnetic rotor 1, thereby causing the sensing plate 5 to rotate. The light signal generator 6 emits a light signal. Due to the rotation of the sensing plate 5, the light signal alternately illuminates the blade portion 51 and the groove 52. The host computer determines whether the rotor 2 to be operated is magnetized based on the changes in the light signal received by the sensing plate 5. This setup enables automatic detection, avoids human error, and improves detection accuracy.

[0038] In this embodiment, the rotor assembly method on the assembly line of electronic products with rotors includes rotor magnetization, impeller assembly, and a magnetization detection step for the rotor 2 to be operated, after the rotor magnetization and impeller assembly; the magnetization detection step is performed synchronously with the impeller flatness test of the rotor 2 to be operated; specifically, it includes the following steps.

[0039] The rotor 2 to be operated is magnetized, and the impeller 3 is welded to the rotor 2. Subsequently, the magnetization of rotor 2 is checked during the process of checking the flatness of impeller 3. The two processes of welding the impeller and magnetizing the rotor to be operated can be performed simultaneously: magnetizing rotor 2 and welding impeller 3 to rotor 2; magnetizing rotor 2 first and then welding impeller 3 to rotor 2; or welding impeller 3 to rotor 2 and then magnetizing rotor 2.

[0040] like Figure 3 , 4 As shown, the impeller 3 is welded to the rotor 2 to be worked, and the rotor 2 to be worked, after the impeller is welded, is fixed to the rotor housing 8. The motor is started, and the power of the motor drives the second magnetic rotor 71 to rotate through the second rotating shaft 73. The rotation of the second magnetic rotor 71 generates the first rotating magnetic field.

[0041] Adjust the position of the first magnetic rotor 1 of the first detection module 100 so that the rotor 2 to be operated after welding the impeller is located in the first rotating magnetic field generated by the magnetic field generator 7, and the first magnetic rotor 1 is located outside the first rotating magnetic field generated by the magnetic field generator 7; so that the distance between the first magnetic rotor 1 and the rotor receiving position 82 of the rotor receiving seat 8 to be operated is within the magnetic field coverage of the magnetized target rotor.

[0042] If the sensing element 5, which is coaxially connected to the first magnetic rotor 1 in the first detection module 100, does not rotate, the automatic detection module 4 of the first detection module 100 determines that the rotor 2 to be operated is not magnetized; or, if the sensing element 5, which is coaxially connected to the first magnetic rotor 1 in the first detection module 100, rotates, the automatic detection module 4 of the first detection module 100 determines that the rotor 2 to be operated is magnetized.

[0043] In this state, the sensing component 200 of the impeller flatness detection device contacts the upper surface of the impeller 3 to test the flatness of the rotor assembly. Impeller flatness testing and rotor magnetization testing are completed at the same station.

[0044] Thus, by testing the rotor magnetization at the same station during the impeller 3 flatness testing process, the existing impeller 3 flatness testing equipment can be used to set the rotor magnetization, improving equipment utilization and reducing testing costs. Simultaneously, the automatic detection module 4 determines the magnetization of the rotor to be tested, further improving the automation level of the assembly line, reducing human error, and consequently increasing the assembly line yield and reducing production costs.

[0045] In one embodiment, the second magnetic rotor 71 can be driven by a motor, manually rotated, driven by a coil, or otherwise.

[0046] In another specific embodiment, such as Figure 5As shown, the second target operation detection includes a rotor dynamic balancing test, and the rotor housing 8 to be tested is located in the test equipment for the rotor dynamic balancing test.

[0047] In this embodiment, the first detection module 100 can adopt a structure roughly similar to that of the previous embodiment. The dynamic balancing equipment includes a mechanism capable of driving the rotor 2 to be tested on the rotor receiving seat 8 to rotate. The magnetic field generator 7 may not be set separately, but may be a structure with similar function set in the dynamic balancing test equipment. The magnetic field generator may also be set separately, with a structure and function similar to that of the previous embodiment or other devices capable of generating a first rotating magnetic field.

[0048] In this embodiment, rotor assembly on the assembly line includes rotor magnetization, rotor dynamic balancing testing, and rotor magnetization detection. Specifically, after rotor magnetization, rotor dynamic balancing testing and rotor magnetization detection are performed at the same workstation, including the following steps:

[0049] Fix the rotor 2 to be operated to the rotor receiving seat 8, and adjust the position of the first magnetic rotor 1 of the first detection module 100 so that the distance between the first magnetic rotor 1 and the rotor receiving position 82 of the rotor receiving seat 8 is within the magnetic field coverage range of the magnetized target rotor.

[0050] This causes the rotor 2 under test to rotate. Specifically, the rotor housing 8 is located in the rotor dynamic balancing equipment. Under the drive of the dynamic balancing equipment, the rotor 2 under test rotates around its axis.

[0051] If the first magnetic rotor 1 does not rotate, the rotor 2 to be operated is deemed unqualified; or, if the first magnetic rotor 1 rotates, the rotor 2 to be operated is deemed qualified.

[0052] The dynamic balance test and magnetization test of the rotor 2 to be operated are completed at the same workstation.

[0053] The dynamic balancing test equipment for rotor dynamic balancing test rotates the rotor 2 to be operated to detect its dynamic balance performance. With the first magnetic rotor 1, as described above, the use of additional power energy can be reduced to simultaneously test whether the rotor 2 to be operated is magnetized. The method is simple and helps to improve rotor assembly efficiency.

[0054] In this embodiment, the first magnetic rotor 1 can also be driven to the automatic detection module 4. The automatic detection module 4 receives the rotation signal of the first magnetic rotor 1 and determines that the rotor 2 to be operated is magnetized. Conversely, if the detection module 4 does not detect the rotation of the first magnetic rotor 1, it determines that the rotor 2 to be operated is not magnetized. Specifically, if the sensing element 5, which is coaxially driven to the first magnetic rotor 1 in the first detection module 100, does not rotate, the automatic detection module 4 of the first detection module 100 determines that the rotor 2 to be operated is not magnetized; if the sensing element 5, which is coaxially driven to the first magnetic rotor 1 in the first detection module 100, rotates, the automatic detection module 4 of the first detection module 100 determines that the rotor 2 to be operated is magnetized. Using the detection module 4 to detect the rotation signal of the first magnetic rotor 1 results in a higher degree of digitalization in the detection method, reducing the possibility of misjudgment due to manual judgment and improving the accuracy of the detection.

[0055] The above examples illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the present invention.

The first target operation inspection is performed simultaneously with the dynamic balance inspection or flatness inspection of the rotor (2) to be operated, or the first target operation inspection is performed before the dynamic balance inspection or impeller flatness inspection of the rotor (2) to be operated.

10. The assembly method according to claim 8 or 9, characterized in that, The step "to rotate the rotor (2) to be worked" includes: Adjust the position of the first magnetic rotor (1) of the first detection module (100), start the magnetic field generator (7), so that the rotor (2) to be operated is located in the first rotating magnetic field generated by the magnetic field generator (7), so that the first magnetic rotor (1) is located outside the first rotating magnetic field generated by the magnetic field generator (7), so that the magnetic field generator (7) drives the rotor (2) to be operated to rotate. The step "perform first target operation detection on the rotor (2) to be operated" includes: if the sensing plate (5) in the first detection module (100) is coaxially connected to the first magnetic rotor (1) and does not rotate, the automatic detection module (4) of the first detection module (100) determines that the rotor (2) to be operated is not magnetized; if the sensing plate (5) in the first detection module (100) is coaxially connected to the first magnetic rotor (1) and rotates, the automatic detection module (4) of the first detection module (100) determines that the rotor (2) to be operated is magnetized.
