Description

Technical Field

[0001] The utility model relates to the technical field of electronic water pump motors, in particular to an automatic assembly device for stators and rotors of electronic water pump motors and a control system. Background Art

[0002] The components of the automotive electronic water pump include a rear cover, a drive circuit board, a stator, a motor housing, a rotor, a motor shaft and a water pump housing, such as the content disclosed in the Chinese utility model patent application with application announcement number CN204532856U and the name "An automotive electronic water pump". At present, although automotive electronic water pumps have a wide range of applications due to their excellent performance, they still lack reliable and efficient production processes. There are many production steps for automotive electronic water pumps, which can generally be roughly divided into processes such as rotor magnetization, stator and rotor assembly, front cover and bracket installation, bracket glue coating and program loading, socket installation and soldering, resistance welding, rear cover installation, no-load testing, and packaging. Among them, the core components of the automotive electronic water pump: the assembly of the stator and the rotor, that is, the magnetized rotor stator is installed in the hollow inner cavity of the stator and the stator and rotor are kept coaxial, which basically relies on manual assembly. The commonly used method is mainly to rely on workers to manually put the rotor into the stator, but because the magnetic steel is attached to the rotor, it is easy to cause the stator and the rotor to attract together to produce friction and damage the stator and rotor surface. At the same time, the graphite bearing on the lower end cover of the stator cannot control the speed of the rotor being placed into the stator, and when the rotor shaft is inserted into the graphite bearing on the lower end cover of the stator, the speed is too fast and the graphite bearing will be damaged, and the graphite bearing is fragile. Therefore, the existing assembly quality does not meet the process requirements, so this method is not only time-consuming and labor-intensive, but also has low production efficiency and low pass rate.

[0003] Based on this, the present utility model is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Please refer to Figures 1 to 5 shown.

[0037] Example 1

[0038] An automatic assembly device for the stator and rotor of an electronic water pump motor according to this embodiment includes:

[0039] The assembly platform 400 includes a platform 431 and a stator seat 432 mounted on the platform 431 , and a stator 434 is mounted on the stator seat 432 ;

[0040] The first assembly mechanism 100 is movably disposed on one side of the assembly platform 400 and located at one end of the stator seat 432, and is used to install the rotor 435 into the stator 434;

[0041] The second assembly mechanism 200 is movably disposed on the other side of the assembly platform 400 and located at the other end of the stator seat 432, and is used to cooperate with the first assembly mechanism 100 to tightly assemble the rotor 435 and the stator 434;

[0042] During assembly, the central axes of the stator 434 and the rotor 435 coincide. This is reflected in the positional relationship, that is, when the stator 434 installed on the stator seat 432 and the first assembly mechanism 100 grabs the rotor 435 and is ready to be installed in the stator 434, the central axes of the stator 434 and the rotor 435 coincide. In this embodiment, preferably, the central axis of the second assembly mechanism 200 during assembly also coincides with the central axis of the stator 434 to ensure the assembly effect of the second assembly mechanism 200. More preferably, the central axis of the stator seat 432 coincides with the central axis of the stator 434 to ensure that the stator 434 can coincide with the central axis of the stator seat 432 when installed on the stator seat 432, which is convenient for accurate installation and assembly.

[0043] In this embodiment, the first assembly mechanism 100 is preferably located above the assembly platform 400, and the second assembly mechanism 200 is located below the assembly platform 400, forming an upper-middle-lower structure. In other optional solutions, the first assembly mechanism 100, the assembly platform 400, and the second assembly mechanism 200 can adopt a left-middle-right / front-middle-back structure, all of which are within the protection scope of the present invention.

[0044] The assembly device of this embodiment cooperates with the first assembly mechanism 100 and the second assembly mechanism 200. During assembly, the central axes of the stator 434 and the rotor 435 coincide with each other, thereby realizing machine assembly instead of manual assembly. The assembly efficiency is improved, the labor intensity of workers is reduced, and collision between the stator and the rotor is avoided. The assembly process is correctly controlled to ensure accurate assembly, improve the qualified rate of shipped products, and improve economic benefits.

[0045] The assembly device of this embodiment can control the speed of the assembly action while realizing machine assembly, and cooperates with the second assembly mechanism 200 to avoid the phenomenon that the graphite bearing on the lower end cover of the stator cannot control the speed of the rotor being placed into the stator too fast during assembly and damages the graphite bearing, thereby ensuring the assembly quality and improving the qualified rate.

[0071] For the electronic water pump motor stator and rotor automatic assembly device of this embodiment, a control system is provided for controlling the electronic water pump motor stator and rotor automatic assembly device given in the embodiment, please refer to Figure 6 and Figure 7 , including a control center 500, a first solenoid valve 112, a second solenoid valve 212, a third solenoid valve 312, a clamping solenoid valve 174, a pressure sensor 134 and a plurality of limit sensors connected to the control center 500, namely a first drive upper limit sensor 151, a first drive lower limit sensor 152, a second drive upper limit sensor 251, and a second drive lower limit sensor 252.

[0072] Please refer to Figure 6 In this embodiment, the control center 500 adopts a PLC control center. In this embodiment, the more specific control process is as follows:

[0073] The worker puts the stator 434 into the stator seat 432, and then puts the upper end shaft of the rotor 435 into the position of the clamping claw 171, and then presses the start button. At this time, the third solenoid valve 312 controlling the third cylinder 311 receives a signal from the PLC and is energized. The third cylinder 311 is ventilated to press the stator 434. Similarly, the clamping claw 171 of the clamping cylinder 173 clamps the rotor 435. After a certain delay, the PLC control center controls the second solenoid valve 212 of the second cylinder 211 to receive a signal from the PLC and is energized. The second cylinder 211 is ventilated to move. After the receiving rod 231 moves upward for a certain displacement, the first cylinder 111 drives the first connecting plate 131, the second connecting plate 132, the third connecting plate 133, and the clamping cylinder 173 connected thereto to move downward together, inserting the rotor 435 clamped by the clamping claw 171 into the stator 434. During the insertion process, the lower end shaft of the rotor 435 contacts and presses against the receiving rod 231 (the lower end shaft of the rotor 435 contacts the receiving rod 231 connected to the second cylinder 211, and the second cylinder 211 moves the receiving rod 231 slowly downward), and the pressure is transmitted. After the sensor 143 senses a certain force value signal and transmits it to the PLC, the second solenoid valve 212 controlling the second cylinder 211 is energized, the second cylinder 211 is ventilated, and the receiving rod 231 moves down slowly, and the second cylinder 211 returns to its original position. At the same time, the action of the first cylinder 11 also drives the first connecting plate 131, the second connecting plate 132, the third connecting plate 133, and the clamping cylinder 173 connected thereto to move down together, inserting the rotor clamped by the clamp 171 into the stator 434. At this time, the pressure sensor 143 senses a certain force signal again and transmits it to the PLC. LC (rotor lower end bearing gear and lower end cover bearing are pressed), and the first limit drive limit sensor 152 of the first cylinder 111 senses the position signal and transmits it to PLC. The two signals are transmitted to the PLC control center to send out a qualified signal. On the contrary, if the PLC control center only receives one signal or no signal, it sends out an alarm signal. At this time, the clamping solenoid valve 174 of the clamping cylinder 173 receives the power-off signal from the PLC, and the clamping cylinder 173 is deflated and released. Then the first cylinder 11 returns to its position, the pressing cylinder is released, and the whole process ends. The assembly efficiency is improved by using this device, the labor intensity of workers is reduced, the collision of stator and rotor is avoided, the assembly process is correctly controlled, the qualified rate of factory products is improved, and the economic benefits are increased. The above is a detailed introduction to an automatic assembly device and control system for stator and rotor of an electronic water pump motor provided by the present application. This article uses specific examples to explain the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application.
