Description

Technical Field

[0001] The utility model relates to the technical field of magnetization, in particular to an error-proof tooling for magnet magnetization. Background Art

[0002] Bipolar magnetization is a specific magnetization method used to form two symmetrical magnetic poles on a magnet. This unique magnetic field structure is often used in power conversion equipment such as motor systems and generators. This magnetic field structure significantly increases the strength and uniformity of the magnetic field, thereby enhancing the overall performance and efficiency of the equipment.

[0003] However, traditional magnetization methods often adopt a one-by-one approach, that is, only one magnet is magnetized at a time. This method is not only inefficient, but also difficult to meet the needs of modern industrial production for batch production and high efficiency.

[0004] Furthermore, in addition to the common cube magnets, there are also some magnets with inconsistent front and back sides, such as magnets used in wiper motor sensors. The traditional magnetization process is very prone to the problem of confusion between the front and back magnetization, which directly reduces the product yield.

[0005] Therefore, the applicant intends to propose a tool for preventing errors in magnetizing magnets to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a tool for preventing errors in magnetizing magnets, which not only has high magnetizing efficiency but also accurately positions magnets to avoid misplacing magnets, thereby increasing the yield rate.

[0007] To achieve the above-mentioned purpose, the solution of the present invention is: a tool for magnetizing and preventing errors, comprising a driving device, a loading member, a push plate, a bipolar magnetizing device and a cooling device;

[0008] A driving device, the driving device including an output end, the output end being fixedly connected to the object carrier, and the output end driving the object carrier to slide in a horizontal direction;

[0009] The object carrier is provided with a plurality of contoured positioning grooves, the contoured positioning grooves are used to place magnets, and the contoured positioning grooves are completely wedged with the shape of the front or back side of the magnet;

[0010] A push plate is provided on the top of the object carrier, the bottom surface of the push plate is parallel to the top surface of the object carrier, and the push plate is used to push the magnet outside the contour positioning groove;

[0011] A bipolar magnetizing device, which is disposed below the object carrier and is used to magnetize the magnet placed on the object carrier;

[0012] A cooling device is provided below the bipolar magnetizing device and is used for dissipating heat from the bipolar magnetizing device.

[0013] Furthermore, it also includes an outer shell, which is a cubic shell with an opening on the top. The object carrier is arranged at the opening of the outer shell, and the object carrier slides horizontally along the plane of the opening. The bipolar magnetizing device and the cooling device are arranged inside the outer shell.

[0014] Furthermore, an extension portion is provided on the side of the object carrier parallel to the sliding direction, the extension portion fits the side wall of the shell, and the extension portion is used for sliding guidance of the object carrier.

[0015] Furthermore, it also includes a baffle, which is arranged at one end of the object carrier connected to the output end. When the object carrier transports the magnet to the magnetizing position of the bipolar magnetizing device, the baffle restricts the object carrier from continuing to slide.

[0016] Furthermore, the push plate is a wedge, and one end of the push plate with an inclined surface pushes against the magnet.

[0017] Furthermore, the driving device is a cylinder, and the output end is an output rod of the cylinder.

During the operation, the load is uniformly placed on the magnets, and the contoured positioning groove ensures that the magnets are accurately positioned. Then the push plate pushes out the magnets placed in the opposite direction to ensure that the magnets are correctly magnetized, thereby improving the product yield. The magnetization operation process is simple and has a high tolerance for workers' mistakes. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that when a component is considered to be “connected” to another component, it may be directly connected to the other component or there may be a centrally located component at the same time.

[0030] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0031] The utility model provides a tool for preventing errors in magnetizing magnets, comprising a driving device 1, an object carrier 2, a push plate 3, a bipolar magnetizing device 4 and a cooling device 5.

[0032] The object carrier 2 is provided with a plurality of contoured positioning grooves 21, which are used to place magnets. The contoured positioning grooves 21 are completely wedged with the shape of the front or back of the magnet; when the tooling needs to magnetize the front of the magnet, the contoured positioning grooves 21 are completely wedged with the shape of the front of the magnet. If the worker accidentally places it on the back, the magnet will protrude from the contoured positioning grooves 21. When the tooling needs to magnetize the back of the magnet, the contoured positioning grooves 21 are completely wedged with the shape of the back of the magnet. If the worker accidentally places it on the front, the magnet will protrude from the contoured positioning grooves 21.

[0033] The drive device 1 includes an output terminal 11 fixedly connected to the object carrier 2 and driving the object carrier 2 to slide horizontally; the horizontal movement distance and time of the output terminal 11 can be set. A push plate 3 is disposed on top of the object carrier 2, with its bottom surface parallel to the top surface of the object carrier 2 and used to push the magnet outside the contoured positioning groove 21. A bipolar magnetizing device 4 is disposed below the object carrier 2 and is used to magnetize the magnet placed on the object carrier 2.

[0034] When the tooling is working, first, the output end 11 drives the object carrier 2 to slide forward in the horizontal direction and then stops for a period of time. During this period of time, the operator places the magnet on the object carrier 2. The operator does not need to check the front and back of the magnet, which simplifies the operation difficulty. Next, the output end 11 drives the object carrier 2 to slide backward in the horizontal direction and stops for a period of time. At this time, the output end 11 brings the object carrier 2 under the push plate 3. The push plate 3 pushes out the incorrectly placed magnet, and the incorrectly placed magnet leaves the object carrier 2. The object carrier 2 stays above the bipolar magnetizing device 4. During this period of time, the bipolar magnetizing device 4 magnetizes the magnet on the object carrier 2. Finally, the magnetization is completed, and the output end 11 drives the object carrier 2 to slide forward in the horizontal direction and then stops for a period of time. During this period of time, the operator removes the magnet. At this point, the magnetization of a batch of magnets is completed.

[0035] A cooling device 5 is provided below the bipolar magnetizing device 4 to dissipate heat from the bipolar magnetizing device 4. When the bipolar magnetizing device 4 is operating, it generates a large amount of heat. To ensure that the tooling is not damaged during continuous operation, a cooling device 5 is provided below the bipolar magnetizing device 4 to remove the heat generated during operation.

[0036] The tooling also includes a housing 6, which is a cubic shell with an opening at the top. The object carrier 2 is mounted in the opening of the housing 6, and the object carrier 2 slides horizontally along the plane of the opening. The bipolar magnetizing device 4 and the cooling device 5 are disposed within the housing 6. The housing 6 is used to protect the bipolar magnetizing device 4 and the cooling device 5, extending the service life of the tooling, and provides support for the object carrier 2, allowing the object carrier 2 to slide stably in the horizontal plane.

[0037] Extensions 22 are provided on the sides of the object carrier 2 parallel to the sliding direction. These extensions 22 engage the sidewalls of the housing 6 and serve as guides for the sliding movement of the object carrier 2. While the drive device 1 may cause the object carrier 2 to slide, the housing 6 provides vertical support for the object carrier 2, while the extensions 22 provide horizontal guidance. This allows the object carrier 2 to more stably transport the magnets along the designed path.

[0038] The baffle 7 is also included. The baffle 7 is set at the end of the object carrier 2 connected to the output end 11. When the object carrier 2 transports the magnet to the magnetizing position of the bipolar magnetizing device 4, the baffle 7 limits the object carrier 2 from sliding further. Although the driving device 1 is set with a sliding distance, in order to make the magnetizing position more accurate, the baffle 7 is designed to be positioned. When the tooling is running, when the driving device 1 drives the object carrier 2 to slide to the magnetizing position, the baffle 7 abuts against the object carrier 2. Figure 2 In one embodiment, the baffle 7 and the push plate 3 are made into an integrated structure. Of course, the baffle 7 and the push plate 3 can also be designed as separate parts, which is not limited in this case.

[0039] The push plate 3 is a wedge, and one end of the push plate 3 is inclined to push the magnet. The push plate 3 of the wedge can more easily shovel the wrongly placed magnet away from the object carrier 2.

[0040] The driving device 1 is a cylinder, and the output end 11 is an output rod of the cylinder. The cylinder has stable output and can work normally in harsh environments such as high and low temperatures, strong magnetism, radiation and vibration, and is very suitable for magnetizing environments.

[0041] The cooling device 5 includes a pipeline, and cooling water flows through the pipeline. Water cooling is environmentally friendly and pollution-free, meeting environmental protection requirements.

[0042] The bottom of the contoured positioning groove 21 is provided with a through hole 211 for an operator to remove the magnetized magnet. To remove the magnet, the operator extends a finger or a push rod from the through hole 211, and the magnet engaged with the contoured positioning groove 21 is pushed out, allowing the operator to easily remove the magnet.

[0043] In one embodiment, the object carrier 2 is provided with four contoured positioning grooves 21, which are completely inlaid with the shape of the front surface of the magnet.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
