Description

Technical Field

[0001] This invention relates to a magnet bonding apparatus and a magnet bonding method. Background Technology

[0002] In an electric motor, magnets need to be installed inside. The performance of the motor is usually limited by the flux density of the magnet. As a common practice, the flux density can be increased by using magnets made of materials with high magnetic energy density or large thickness. Alternatively, magnet assemblies / components with large flux density can be installed. These magnet assemblies / components are generally made by bonding multiple magnets in a specific order. Because the magnets are prone to flying off due to the magnetic force between them during the bonding process, the manufacturing process is very difficult and therefore the production cost is high.

[0021] In a preferred embodiment, the magnetic polarity vectors of the adjacent magnets have an angle of 30° to 60°.

[0022] In a preferred embodiment, the magnetic polarity vectors of the adjacent magnets have an angle of 45°.

[0023] In a preferred embodiment, 4N magnets are arranged at intervals in a specific order on the base, where N is a natural number.

[0024] In a preferred embodiment, N=1 or N=2.

[0025] In a preferred embodiment, the magnet closest to the blocking part has a magnetic polarity vector that forms an angle of 0° to 60° with the horizontal plane.

The X-axis and Y-axis form a planar coordinate system. Based on this planar coordinate system,

[0028] The step of arranging magnets with different magnetic polarity vectors on the base in a specific order and at intervals includes arranging four magnets on the base at one of the following specific orders and intervals:

[0029] The first specific order is: the magnetic polarity vector of the magnet closest to the blocking part is 45°, and the magnetic polarity vector of the magnet closest to the pressure part of two adjacent magnets has an angle of -45° with respect to the magnetic polarity vector of the magnet closest to the blocking part.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1, refer to Appendix Figure 1 ~Appendix Figure 5 .

[0061] This embodiment provides a magnet bonding device, which is configured to bond multiple magnets together to form a magnet assembly. The device includes: a base 10, a blocking portion 20, and a pressure-applying portion 30. The base 10 is configured to attract magnets to its surface, for example, the base 10 is made of ferromagnetic material, and the magnets are not easily dropped when attracted to the base 10. The blocking portion 20 is configured to suppress the movement of the magnets under the action of force when they come into contact with the blocking portion 20, facilitating the bonding between the magnets. The base 10 and the blocking portion 20 are integral or assembled together. The pressure-applying portion 30 can move relative to the blocking portion 20 and can apply force to the magnets. It is a force-applying component for bonding the magnets. The pressure-applying portion 30 allows multiple magnets to come into direct or indirect contact with the blocking portion 20, pressing these magnets tightly onto the blocking portion 20. After a period of time, the bonding material between the magnets solidifies, completing the bonding between the magnets.

[0062] Preferably, the adhesive is glue.

[0063] It should be noted that the term "multiple" in this invention refers to two or more.

[0064] Preferably, the pressure-applying part 30 can be mounted on the base 10, for example, attached to... Figure 1 As shown, the base 10 has a connecting part 19, and the pressure part 30 is connected to the connecting part 19 of the base 10 through a lead screw 32. The lead screw 32 is rotatably connected to the pressure part 30. By rotating the lead screw 32, the pressure part 30 can be driven to move. At the same time, due to the self-locking effect of the lead screw 32 itself, the magnetic force between the magnets can be prevented from driving the pressure part 30 to move in the opposite direction.

[0065] Preferably, the device further includes a side portion 40, which is integral with or assembled with the base 10. The side portion 40 can attract magnets to its surface; for example, the side portion 40 is also made of a ferromagnetic material. (See attached diagram.) Figure 1 Appendix Figure 2 The base 10 attracts the magnet longitudinally, while the side portion 40 attracts the magnet laterally. The attraction forces generated by the base 10 and the side portion 40 prevent the magnet from flying off during the bonding process (when the pressure portion 30 moves towards the blocking portion 20). Furthermore, the side portion 40 has two locations, symmetrically arranged on both sides of the base 10, which further makes the magnet less prone to flying off.

[0066] See attached document Figure 1Due to the presence of the base 10 and the side portion 40, the magnet cannot be launched downwards or to the side. However, during the magnet bonding process, as the distance between adjacent magnets gets closer, the attraction force of the base 10 to a certain magnet adsorbed on its upper surface may be insufficient to suppress the magnet's launch, causing the magnet to launch upwards. To solve this problem, preferably, the pressure application portion 30 is provided with a protruding portion 31 that can suppress the magnet's launch. The protruding portion 31 can suppress at least one magnet on the base 10: for example, attached... Figure 1 As shown, the width w of the protrusion 31 matches the thickness of a magnet, and the protrusion 31 can only restrain one magnet missile; for example, attached Figure 2 As shown, at this time, the width w of the protrusion 31 is at least greater than the sum of the thicknesses of all the magnets adsorbed on the base 10, and the protrusion 31 can restrict all the magnet missiles on the base 10.

[0067] The above structure enables the bonding of multiple magnets. However, because the base 10, side portions 40, and other locations can attract the magnets, the bonded magnet assembly tends to adhere to the bottom of the device and is difficult to remove. To solve this problem, preferably, refer to the attached... Figure 3 ~Appendix Figure 5 The device also includes a base 50, a base 10 mounted on the base 50 and the base 10 being movable relative to the base 50. The base 10 has a hollow area 11 on the side near the blocking part 20. The base 50 has a top block 51 extending into the hollow area 11. With this structure, when the operator pushes the base 10 to one side of the base 50, the top block 51 on the base will pass through the hollow area 11 and push out the magnet assembly. At this time, the operator can take off the magnet assembly.

[0068] Preferably, in order to facilitate the reset of the base 10, the base 50 is provided with two positioning holes 52, and two positioning posts 12 are connected to the base 10. The positioning holes 52 can slide along the positioning posts 12, so that the base 10 can slide up and down on the base 50. A spring 53 is also provided between the base 50 and the base 10. The spring 53 is configured to drive the base 10 to reset.

[0069] Preferably, in order to achieve automated operation, the device also includes a hydraulic cylinder 60, which is configured to drive the base 10 to press down toward the base 50, thereby replacing manual operation of the base 10.

[0070] Example 2, refer to Appendix Figure 6 ~Appendix Figure 14 .

[0071] A magnet bonding method, using the magnet bonding device of Embodiment 1, includes the following steps: magnets with different magnetic polarity vectors are placed on a base 10 at intervals in a specific order, with one end of each magnet adsorbed onto the side portion 40. An adhesive is applied to the surface of the magnets to be bonded. At this point, the operator can bring the magnets close together with their fingers until they stick together, or the magnets are placed close enough that adjacent magnets attract each other until they stick together. In this embodiment, to ensure high bonding quality, the magnets are gradually pushed together by driving the pressure application portion 30 to form a magnet assembly that abuts against the blocking portion 20. After maintaining this position for a period of time, the pressure application portion 30 is removed, and the magnet assembly is taken off.

[0072] To facilitate understanding of the invention by those skilled in the art and for ease of description, the horizontal ray pointing from the blocking part 20 to the pressure-applying part 30 is defined as the positive X-axis direction, and the vertical ray perpendicular to the positive X-axis direction and pointing vertically upwards is defined as the positive Y-axis direction. The X-axis and Y-axis form a planar coordinate system, as shown in the attached figure. Figure 1 Appendix Figure 2 The coordinate system is shown in the diagram.

[0073] In this invention, the magnetic polarity vector of the magnet is represented by an arrow in the accompanying drawings. The direction of the magnetic polarity vector of the magnet can be from the S pole to the N pole, or from the N pole to the S pole, both of which are applicable to the magnet bonding method of this invention.

[0074] In this invention, the surface to be pasted is specified as at least one of the opposing surfaces of the two magnets. For better understanding by those skilled in the art, the following is provided: Figure 14 Examples are provided, with appendices. Figure 14 The diagram shows magnets 99, 98, 97, and 96 arranged at intervals. If magnets 99 and 98 need to be bonded together, the surfaces to be bonded are surface 95 of magnet 99 and / or surface 94 of magnet 98. Applying the adhesive only needs to be done on surface 95 and / or surface 94.

[0075] Preferably, in this invention, a specific order refers to the fact that, in one direction, the magnetic polarity vectors of adjacent magnets have the same angle, for example, [the following is an example of a specific sequence]. Figure 14 In the diagram, the magnetic polarity vector of magnet 99 is 180°, that of magnet 98 is 135°, that of magnet 97 is 90°, and that of magnet 96 is 45°. These four magnets are arranged in a specific order, with an angle of 45° between adjacent magnets.

[0076] Preferably, the magnetic polarity vectors of adjacent magnets have an angle of 30° to 60°. Further, the magnetic polarity vectors of adjacent magnets have an angle of 45°, for example, [missing information]. Figure 6 ~Appendix Figure 13 As shown. Correspondingly, 4N magnets are arranged at intervals in a specific order on the base 10, where N is a natural number. When 4N magnets are arranged at intervals in a specific order on the base 10, the magnet bonding device in Embodiment 1 can bond 4N magnets together into a magnet assembly at one time. The more magnets bonded at once, the higher the bonding efficiency, but it also brings a higher bonding failure rate. The inventors of this application found in practice that bonding 4 or 8 magnets at a time results in a high bonding success rate. Therefore, N=1 or N=2 is preferred.

[0077] Furthermore, the inventors of this application discovered in practice that when using an adhesive device with a long protruding portion 31 (the width w of the pressure portion 30 is greater than the sum of the thicknesses of all magnets adsorbed on the base 10), adhesive failures occur in a few cases. Generally, one magnet on the base 10 flips over, or one magnet in the bonded magnet assembly slightly protrudes upwards. After investigation, the inventors of this application found that this is caused by the mutual repulsion between the magnets; that is, the adsorption force provided by the base 10 and the side portion 40 is insufficient to suppress the repulsion between the magnets, causing one magnet to detach from the base 10 and / or the side portion 40, resulting in a bonded magnet assembly that does not meet the requirements. To address this issue and improve the success rate of each bonding attempt, the inventors of this application place a magnet with a specific magnetic polarity vector direction at the first magnet position on the base 10 (the position closest to the blocking part 20). This makes the magnet at the last magnet position on the base 10 (the position closest to the pressure application part 30) the easiest magnet to launch. Simultaneously, the width w of the protrusion 31 of the pressure application part 30 matches the thickness of a magnet, effectively suppressing the launch of the magnet at the last position. This achieves a 100% success rate for each bonding attempt. Preferably, since adjacent magnets have different angles between their magnetic polarity vectors, the magnet closest to the blocking part 20 has a magnetic polarity vector forming an angle of 0° to 60° with the horizontal plane. Furthermore, in a scheme where the magnetic polarity vectors of adjacent magnets have an angle of 45°, and 4N magnets are placed on the base 10 in a specific order, the magnet closest to the blocking part 20 has a magnetic polarity vector that forms an angle of 0° or 45° with the horizontal plane. It should be noted that the angle here is based on the horizontal plane, not on a coordinate system.

[0078] More specifically, when N=1, that is, when the magnetic polarity vectors of adjacent magnets have an angle of 45°, and four magnets are placed on the base 10 in a specific order, the present invention provides eight preferred solutions.

[0079] Option 1: Refer to the attached document Figure 6 The magnet closest to the blocking part 20 has a magnetic polarity vector of 45°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets has an angle of -45° relative to the magnetic polarity vector of the magnet closest to the blocking part. Option Two: Refer to Appendix Figure 7 The magnet closest to the blocking part 20 has a magnetic polarity vector of -135°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets has an angle of -45° relative to the magnetic polarity vector of the magnet closest to the blocking part. Scheme 3: Refer to Appendix Figure 8 The magnet closest to the blocking part 20 has a magnetic polarity vector of -45°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets forms a 45° angle with the magnetic polarity vector of the magnet closest to the blocking part. Scheme Four: Refer to Appendix Figure 9 The magnet closest to the blocking part 20 has a magnetic polarity vector of 135°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets forms a 45° angle with the magnetic polarity vector of the magnet closest to the blocking part. Option Five: Refer to Appendix Figure 10 The magnet closest to the blocking part 20 has a magnetic polarity vector of 0°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets forms a 45° angle with the magnetic polarity vector of the magnet closest to the blocking part. Scheme Six: Refer to Appendix Figure 11 The magnet closest to the blocking part 20 has a magnetic polarity vector of 0°. Four magnets are placed on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure part of two adjacent magnets has an angle of -45° with respect to the magnetic polarity vector of the magnet closest to the blocking part.

[0080] Option 7: Refer to Appendix Figure 12 The magnet closest to the blocking part 20 has a magnetic polarity vector of 180°. Four magnets are arranged at intervals on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure application part of two adjacent magnets has an angle of 45° with the magnetic polarity vector of the magnet closest to the blocking part. Scheme Eight: Refer to Appendix Figure 13 The magnet closest to the blocking part 20 has a magnetic polarity vector of 180°. Four magnets are placed on the base 10 in a specific order. The magnetic polarity vector of the magnet closest to the pressure part of two adjacent magnets has an angle of -45° with respect to the magnetic polarity vector of the magnet closest to the blocking part.

[0081] All eight of the above methods can achieve perfect bonding of magnets into magnet components during the bonding process.

[0082] Preferably, the step of removing the magnet assembly includes: driving the hydraulic cylinder 60 to press the base 10 down toward the base 50, the top block 51 on the base 50 is pushed out from the hollow area 11, separating the magnet assembly from the base 10, and the operator removes the magnet assembly.

[0083] Preferably, the magnet assembly obtained by bonding schemes one through eight may require secondary bonding with four other magnet assemblies bonded in the same specific order as schemes one through eight, but with opposite magnetic polarity vector directions, in some applications, such as installation in a motor. This results in a magnet component where the magnetic polarity vectors of the eight magnets point in eight directions, spaced apart, with adjacent magnets having the same angle between their magnetic polarity vectors. Ingeniously, in the above scenario, the magnet assembly of scheme one requires the magnet assembly of scheme two, the magnet assembly of scheme three requires the magnet assembly of scheme four, the magnet assembly of scheme five requires the magnet assembly of scheme seven, and the magnet assembly of scheme six requires the magnet assembly of scheme eight. Since the magnets in these eight schemes are prone to misfire at the last position, the same magnet bonding device can be used for bonding in all of them. Specifically, this invention also provides a magnet bonding method based on magnet assemblies, comprising the following steps:

[0084] The magnets from Schemes 1 to 8 are pasted together as the first group of magnets to obtain the first group of magnet components;

[0085] Four second-group magnets, whose magnetic polarity vectors differ from those of the first-group magnets by 180°, are pasted together to obtain the second-group magnet assembly.

[0086] Following the magnetic polarity vector order of the magnets within the first and second sets of magnet assemblies, the first and second sets of magnet assemblies are placed alternately on the base 10 of the magnet bonding device, allowing them to adhere to the side portions 40. An adhesive is then applied to the surfaces of the first and second sets of magnet assemblies to be bonded. The operator can then bring the magnets close together with their fingers until they stick, or, if the magnets are placed close enough, adjacent magnets will attract each other until they stick together. In this embodiment, to ensure high bonding quality, the first and second sets of magnet assemblies are gradually pushed together by driving the pressure application portion 30 to form a magnet component that abuts against the blocking portion 20. After maintaining this position for a period of time, the pressure application portion 30 is removed, and the magnet component is removed.

[0087] The other implementation methods in this embodiment are the same as in Embodiment 1.

[0088] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
