Description

Technical Field

[0001] The utility model relates to a device for detecting the bonding firmness of a magnetic tile. Background Art

[0002] At present, the magnetic tile is a tile-shaped magnet used in a permanent magnet motor. In most motors, the magnetic tile is bonded to the rotor by glue. In the production process, it is necessary to detect the bonding firmness between the magnetic tile and the rotor. For example, a test device disclosed in the Chinese patent with publication number CN203798713U can be used to detect the bonding firmness between the magnetic tile and the rotor. In some special motors, the magnetic tile needs to be bonded to the stator housing. For example, in some motors that need to use a reverser to control the motor speed and direction, the magnetic tile is bonded to the stator housing by glue. The Chinese patent with publication number CN216936813U discloses an improved tooling for automatic magnetic tile glueing and casing insertion of a four-pole DC split stator, which is used in the process of bonding the magnetic tile to the stator housing. However, there is still a lack of a device in the industry that can detect the bonding firmness between the magnetic tile and the stator housing, so it is impossible to detect the bonding firmness between the magnetic tile and the stator housing.

[0057] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0058] like Figures 1 to 7 As shown, a magnetic tile bonding firmness detection device comprises a frame 1, a tool 2 and at least one detection component 100;

[0059] The tooling 2 is used to place the stator housing 4 bonded with the magnetic tiles 3;

[0060] The detection assembly 100 includes a thrust driving mechanism 5, a force sensor 6, a lower connecting mechanism 7 and a push rod 8;

[0061] One end of the push rod 8 is connected to the lower connecting mechanism 7, and the other end of the push rod 8 is aligned with the magnetic tile 3 in the stator housing 4 in the tooling 2;

[0062] The lower connecting mechanism 7 is connected to one end of the force sensor 6;

[0063] The other end of the force sensor 6 is connected to the thrust drive mechanism 5;

[0064] The thrust driving mechanism 5 is connected to the frame 1, and is used to drive the force sensor 6 to move, thereby driving the lower connecting mechanism 7 and the push rod 8 to move toward the stator housing 4 so that the push rod 8 can support the magnetic tile 3 in the stator housing 4. Specifically, the stator housing 4 bonded with the magnetic tile 3 is placed in the tooling 2, so that the magnetic tile 3 to be detected in the stator housing 4 is aligned with the push rod 8, and the thrust driving mechanism 5 drives the force sensor 6, the lower connecting mechanism 7 and the push rod 8 to move toward the stator housing 4 together, so that the push rod 8 can support the magnetic tile 3 in the stator housing 4, and then the thrust driving mechanism 5 continues to apply force so as to apply thrust to the magnetic tile 3 through the push rod 8, thereby detecting the bonding firmness between the magnetic tile 3 and the stator housing 4, and the magnitude of the thrust can be detected in real time through the force sensor 6.

[0065] In this embodiment, two detection components 100 are arranged in parallel, and the thrust drive mechanism 5, force sensor 6, lower connecting mechanism 7 and push rod 8 in the detection component 100 are arranged in sequence from top to bottom, and the push rod 8 is located above the stator housing 4 in the tooling 2.

[0066] like Figure 1 , 2 , 3, 4, 6, 7, the upper end of the force sensor 6 is connected to the thrust drive mechanism 5, the lower connecting mechanism 7 is connected to the lower end of the force sensor 6, and the upper end of the push rod 8 is floatingly connected to the lower connecting mechanism 7;

[0067] The lower connection mechanism 7 may include a connection seat 9, a slide rod assembly 10, a first spring 11 and a second spring 12. A first boss portion 13 is provided on one side of the upper end of the push rod 8, and a second boss portion 14 is provided on the other side of the upper end of the push rod 8.

[0068] The connecting seat 9 is connected to the lower end of the force sensor 6, and the connecting seat 9 is provided with a first hook portion 15 for supporting the first boss portion 13 and a second hook portion 16 for supporting the second boss portion 14;

[0069] The slide bar assembly 10 is located above the push rod 8, and the slide bar assembly 10 is movably connected to the connecting seat 9 and is suitable for moving up and down relative to the connecting seat 9;

[0070] The first spring 11 is sleeved on the slide bar assembly 10, the lower end of the first spring 11 abuts against the slide bar assembly 10, and the upper end of the first spring 11 abuts against the connecting seat 9;

[0071] The second spring 12 is disposed between the push rod 8 and the slide bar assembly 10 , the upper end of the second spring 12 abuts against the lower end of the slide bar assembly 10 , and the lower end of the second spring 12 abuts against the upper end of the push rod 8 . Specifically, the thrust drive mechanism 5 drives the force sensor 6, the lower connecting mechanism 7 and the push rod 8 to move downward so that the lower end of the push rod 8 abuts against the magnetic tile 3, and then the thrust drive mechanism 5 continues to apply force to drive the force sensor 6 to move downward, and the force sensor 6 will drive the connecting seat 9 to move downward, while the push rod 8 will not move downward because it supports the magnetic tile 3. At this time, the first boss portion 13 will disengage from the first hook portion 15 and the second boss portion 14 will disengage from the second hook portion 16, and the second spring 12 will be compressed. The push rod 8 pushes the slide bar assembly 10 upward through the second spring 12, and the slide bar assembly 10 moves up relative to the connecting seat 9 and compresses the first spring 11. The first spring 11 applies an upward thrust to the connecting seat 9, and the connecting seat 9 transmits the thrust to the force sensor 6, so that the force sensor 6 can detect the magnitude of the thrust in real time. More specifically, the purpose of such a design is that Figure 6 , 7 As shown, the magnetic tile 3 cannot be absolutely horizontal when pasted on the stator housing 4, and there will always be a certain tilt angle. If the push rod 8 can only remain horizontal but cannot float and tilt, the lower end of the push rod 8 cannot form a surface contact with the magnetic tile 3, but a corner of the push rod 8 presses against the top surface of the magnetic tile 3. In this case, the magnetic tile 3 will be crushed, causing the magnetic tile 3 to break and be damaged. In the present embodiment, after the lower end of the push rod 8 presses against the magnetic tile 3, the thrust driving mechanism 5 continues to drive the force sensor 6 and the connecting seat 9 to move downward a certain distance, thereby disengaging the first boss portion 13 from the first hook portion 15 and the second boss portion 14 from the second hook portion 16. Therefore, at this time, the upper end of the push rod 8 and the lower connecting mechanism 7 are floatingly connected, and the push rod 8 can be adaptively tilted so that the lower end of the push rod 8 fits perfectly with the top surface of the magnetic tile 3 to form surface contact, thereby not crushing the magnetic tile 3. The downward thrust applied to the magnetic tile 3 by the push rod 8 can effectively detect the bonding firmness between the magnetic tile 3 and the stator casing 4.

[0074] The connecting seat 9 is provided with a first inclined wall 17 adapted to the side wall of the first boss portion 13 and a second inclined wall 18 adapted to the side wall of the second boss portion 14. When the first inclined wall 17 is in contact with the side wall of the first boss portion 13 and the second inclined wall 18 is in contact with the side wall of the second boss portion 14, the push rod 8 is guided to a central position; specifically, after the detection is completed, the thrust driving mechanism 5 drives the force sensor 6 to move upward, thereby driving the connecting seat 9 to move upward, and then the first hook portion 15 re-supports the first boss portion 13, and the second hook portion 16 re-supports the second boss portion 14, the first inclined wall 17 abuts against the side wall of the first boss portion 13, and the second inclined wall 18 abuts against the side wall of the second boss portion 14; wherein, the first hook portion 15 and the second hook portion 16 can lift the push rod 8 and drive the push rod 8 to move upward, and the first inclined wall 17 and the second inclined wall 18 can guide the push rod 8 to correct its position and thereby enable the push rod 8 to achieve a central position.
