Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron core manufacturing, specifically to a multi-station automatic curing production line for self-bonding iron cores of axial flux motors. Background Technology
[0002] The main method for conventionally curing self-bonded cores for axial flux motors involves fixing the core in a fixture using a positioning mandrel, tightening several adjusting screws on the axial sidewalls to ensure the outer diameter of the core is concentric with the inner hole, assembling the fixture cover, and placing the fixture containing the core into an oven. After approximately 90 minutes of heating, the fixture is removed and cooled. Once cooled, the fixture is opened, and the cured core is removed. This method of curing self-bonded axial flux cores is primarily suitable for small-batch pilot production, as the curing time is too long for mass production. Furthermore, it requires a large number of fixtures and personnel, resulting in high labor intensity, significant variations in product parallelism, perpendicularity, cylindricity, and bonding strength, and making process control difficult. Utility Model Content
[0003] The purpose of this utility model is to solve the problems in the background technology and provide a multi-station automatic curing production line for self-bonding iron cores of axial flux motors.

[0005] Furthermore, the core curing fixture includes a tapered base plate, a tapered positioning plate, and a positioning mandrel. The tapered base plate and the positioning mandrel have the same concentricity, and the inner side of the tapered base plate matches the outer side of the tapered positioning plate and is sleeved on the outer periphery of the core.
[0006] Furthermore, the core curing fixture also includes a pressure plate, a spring, and a cover plate. The pressure plate and the cover plate are fixedly connected by the spring and are sleeved on the outside of the positioning mandrel.
[0007] Furthermore, the induction heating curing module includes a curing press and a medium-frequency induction heating unit disposed on both sides of the conveyor belt.
[0008] Furthermore, the cooling module employs an air shower device.

[0012] Furthermore, a second chiller is provided on one side of the material handling robot.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

Detailed Implementation
[0019] To further understand this utility model, the embodiments and comparative examples will be described in more detail below, but the implementation of this utility model is not limited thereto.
[0020] To make the objectives and technical solutions of this utility model clearer, the following detailed description, in conjunction with examples, further illustrates this utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. The application process of this utility model is described in detail below.
[0021] like Figures 1 to 2 As shown, an axial flux motor self-bonding core multi-station automatic curing production line includes a feeding station 1, a core curing fixture 2, a shaping press 3, multiple sets of induction heating curing modules 4, a detection module 5, a cooling module 6, a laser marking module 7, and a discharge module 8 arranged sequentially along the conveyor belt. The induction heating curing modules 4 are arranged on both sides of the conveyor belt.
[0022] In a specific embodiment, the core curing fixture 2 includes a tapered base plate 21, a tapered positioning plate 22, and a positioning mandrel 23. The tapered base plate 21 and the positioning mandrel 23 have the same concentricity. The inner side of the tapered base plate 21 matches the outer side of the tapered positioning plate 22 and is sleeved on the outer periphery of the core.
[0023] In a specific embodiment, the core curing fixture 2 also includes a pressure plate 24, a spring 25 and a cover plate 26. The pressure plate 24 and the cover plate 26 are fixedly connected by the spring 25 and are sleeved on the outside of the positioning mandrel 23.
[0024] The axial flux motor core is mounted on the positioning mandrel 23 for center positioning. A pressure plate 24, spring 25, and cover plate 26 are then installed. The pressure plate 24 and cover plate 26 have slight gaps on both sides of the positioning mandrel 23, allowing for free movement while still providing a pressing surface. Then, a tapered positioning plate 22 is installed, which mates with a tapered base plate 21. When pressure is applied, the tapered positioning plate 22 and tapered base plate 21 compress the core. During the curing process, as heating and the molten adhesive melt, the tapered positioning plate 22 experiences a downward force, becoming increasingly compacted. When the cured core fixture 2 passes through the forming press 3 station, the downward force is reduced by the spring 25, preventing deformation.
[0025] In a specific embodiment, the induction heating curing module 4 includes a curing press 41 and a medium-frequency induction heating unit 42 disposed on both sides of the conveyor belt.
[0026] In a specific embodiment, the cooling module 5 uses an air shower device.
[0027] The air shower device uses cooling plate technology. After the outside air is cooled by the cooling plate, the cooled air is sprayed into the air shower area by the fan. This effectively reduces the temperature and also reduces impurities in the air in the area, ensuring product quality.
[0028] In a specific embodiment, the discharge module 8 includes a material handling robot 81 and a discharge machine 82. The material handling robot 81 takes out the processed iron core and outputs it to the discharge machine 82.
[0029] In a specific embodiment, the rear end of the material handling robot 81 is also provided with a tooling lifting platform 12, which is used to collect the iron core solidification tooling 2 into the waiting area.
[0030] In a specific embodiment, an air cooler 9 and a first chiller 10 are respectively provided on both sides of the shaping press 3, and the air cooler 9 and the first chiller 10 are electrically connected to the electrical control cabinet.
[0031] The combined use of the air-cooled unit 9 and the first chiller 10 enhances the stability of the entire refrigeration system. The air-cooled unit cools the condenser with air, avoiding problems such as condenser scaling and water pipe blockage caused by water quality issues. The chiller, on the other hand, ensures a constant water temperature through a stable temperature control system, improving the equipment's operational stability and resulting in better cooling performance.
[0032] In a specific embodiment, a second chiller 11 is provided on one side of the material handling robot 81.
[0033] After the iron cores to be cured are loaded at the feeding station 1, they undergo automatic locking, automatic curing, automatic temperature control, automatic pressure control, automatic testing, and laser marking in sequence. This process automatically filters out defective products, ensuring the production of qualified iron cores. Combined with medium-frequency induction heating, the production cycle time is reduced from approximately 90 minutes per piece to 3 minutes per piece. The parallelism and perpendicularity of the produced iron cores are significantly improved, enabling mass production and greatly reducing production costs while improving product quality. Furthermore, by switching to the iron core curing fixture 2, the production of self-bonded iron cores for axial flux motors of different specifications can be achieved, demonstrating high practicality.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents, all of which are included within the protection scope of the present invention.
