The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

The present embodiment provides an apparatus for detecting a position of a magnet. In the case of adding the magnet 104 to the product 100, it is necessary to detect the position of the magnet 104 in the product 100 after the product 100 is assembled, and ensure that the magnet 104 is located at the center of the charging module 103, so that the coil of the charging stand can be aligned with the charging module 103 of the product 100 when the product 100 is wirelessly charged. As shown in fig. 1, the product 100 includes an upper cover 101, a bottom case 102, a charging module 103, and a magnet 104 located in the middle of the charging module 103.

As shown in fig. 2, the apparatus for detecting the position of a magnet includes a detection platform 1, a horizontal driving mechanism 2, a vertical driving mechanism 3, and a magnetic flux detecting member 4. The detection platform 1 is provided with a fixed seat 11 sliding along a first direction X (X direction shown in fig. 2). The horizontal driving mechanism 2 includes a bracket 21 and a horizontal slider 22, and the horizontal slider 22 is slidably disposed on the bracket 21 along a second direction Y (Y direction shown in fig. 2) perpendicular to the first direction X. The vertical driving mechanism 3 includes a lifting slider 31, and the lifting slider 31 is slidably disposed on the horizontal slider 22 along a third direction Z (Z direction shown in fig. 2) perpendicular to the first direction X and the second direction Y. The magnetic flux detector 4 is provided at the bottom of the up-down slider 31.

Because the magnetic induction intensity of the central axis of the N pole or the S pole of the solid magnet 104 is zero, the detection platform 1, the horizontal driving mechanism 2 and the vertical driving mechanism 3 in the device jointly form a 3-axis moving system, so that the magnetic flux detection piece 4 can be moved to any position of the detection platform 1, the magnetic induction intensity outside the product 100 is detected by moving the magnetic flux detection piece 4, and the position with zero magnetic induction intensity can be determined to be the central position of the solid magnet 104.

When the operator needs to detect the position of the magnet 104 in the product 100, the product 100 is placed on the fixing base 11, and the position of the center of the product 100 is located at the origin of coordinates. The product 100 is moved to the position below the magnetic flux detection member 4 through the sliding fixing seat 11, the magnetic flux detection member 4 is positioned right above the origin of coordinates, and the vertical driving mechanism 3 is used for lowering the magnetic flux detection member 4 to a proper height (based on the fact that the magnetic flux detection member 4 can accurately detect the magnetic flux of the magnet 104).

At this time, the operator drives the magnetic flux detection element 4 to scan the product 100 along the second direction Y by using the horizontal driving mechanism 2, and records the magnetic induction intensity values of each position. Then, the fixed base 11 is moved a distance along the first direction X, the product 100 is scanned along the second direction Y again, and the magnetic induction intensity values at the respective positions are recorded. The above operation is repeated until it comes to a stop when the magnetic induction intensity is 0. An operator can obtain the position relationship between the point with the magnetic induction intensity of 0 and the coordinate origin according to the distance of the fixed seat 11 moving along the first direction X and the distance of the point with the magnetic induction intensity of 0 appearing when the magnetic flux detection piece 4 scans along the second direction Y, so as to determine the position of the magnet 104 in the product 100.

Similarly, the operator may also move the fixing base 11 along the first direction X to make the magnetic flux detecting element 4 scan the product 100 along the first direction X, and then move the magnetic flux detecting element 4 along the second direction Y for a distance by using the horizontal driving mechanism 2 and then scan again until the magnetic induction intensity is 0. Both methods can determine the position of the magnet 104 in the product 100, and in practice, the method may be selected according to the length of the product 100 in the first direction X and the second direction Y.

The horizontal driving mechanism 2 further includes a first linear motor, the first linear motor is disposed on the bracket 21 along the second direction Y, and an output end of the first linear motor is fixedly connected to the horizontal sliding block 22. The first linear motor is capable of driving the horizontal slider 22 to move in the second direction Y.

It can be understood that the vertical driving mechanism 3 further includes a second linear motor, the second linear motor is disposed on the horizontal sliding block 22 along the third direction Z, and an output end of the second linear motor is fixedly connected to the lifting sliding block 31. The second linear motor can drive the lifting slide block 31 to drive the magnetic flux detection piece 4 to move along the third direction Z.

As shown in fig. 3 and 4, the apparatus further includes a vacuum-pumping member, and the fixing base 11 is provided with an adsorption hole connected to the vacuum-pumping member. The adsorption holes can adsorb and fix the product 100 to the fixed seat 11, so that the relative position of the product 100 cannot be changed in the scanning process, and the accuracy of the final result is improved.

Preferably, the fixing seat 11 is provided with a clamping assembly 5 along the first direction X, and the clamping assembly 5 includes two clamping members 51, and the two clamping members 51 are slidably disposed on the fixing seat 11 along the first direction X respectively and can be close to or far away from each other. The clamping assembly 5 can further fix the position of the product 100, and prevent the suction holes from generating enough suction force on the product 100 when the product 100 has an irregular shape.

It will be appreciated that the holder 11 is also provided with a clamping assembly 5 in the second direction Y. The two clamping assemblies 5 can clamp the product 100 from the first direction X and the second direction Y, respectively, so as to prevent the product 100 from moving, and to make the position of the finally detected magnet 104 more accurate.

In order to keep the two clamping members 51 clamping the product 100 at all times during scanning, the clamping assembly 5 further comprises two locking screws 52, each locking screw 52 penetrating one of the clamping members 51 and being in threaded connection with the clamping member 51. After the clamping member 51 abuts against the product 100, the operator rotates the locking screw 52 to enable the locking screw 52 to abut against the detection platform 1, so that the clamping member 51 is fixed on the detection platform 1 and cannot move, the product 100 is clamped, and the product 100 cannot move.

Preferably, the clamping assembly 5 further comprises an elastic member 53 and a top block 54, wherein one end of the elastic member 53 is connected to one side of one clamping member 51 close to the other clamping member 51, and the other end is connected to the top block 54. In actual operation, even if the operator presses the two clamping members 51 against the product 100 and then locks the two clamping members with the locking screws 52, a gap inevitably exists between the two clamping members 51 and the product 100, so that the position of the product 100 cannot be fixed. The elastic member 53 can ensure that the top block 54 can tightly press the product 100 against the other clamping member 51, thereby ensuring that the position of the product 100 is not changed. Meanwhile, the elastic member 53 enables the operator to gradually increase the clamping force when clamping the product 100, thereby preventing the product 100 from being damaged.

Preferably, the apparatus further comprises a driving assembly 6, the driving assembly 6 comprises a screw 23 and a driving member 24, the screw 23 extends along the first direction X and is connected to an output end of the driving member 24, and the fixing seat 11 is in threaded connection with the screw 23, as shown in fig. 3. The operator needs to know the distance when the fixing base 11 moves along the first direction X to calculate the position of the magnet 104, and the screw rod 23 is in threaded connection with the fixing base 11, so that the operator can know that the fixing base 11 moves along the first direction X by a pitch distance every time the screw rod 23 rotates by one circle, and the operator can accurately know the moving distance of the fixing base 11. Meanwhile, the screw rod 23 can also play a role in speed reduction, so that the fixing seat 11 can move stably.

As shown in fig. 2 and fig. 5, the detection platform 1 is provided with a slide rail 12 along the first direction X, the bottom of the fixing base 11 is provided with two sliding blocks 111, and the two sliding blocks 111 are respectively located at two sides of the slide rail 12 and are slidably connected to the slide rail 12. The two sliding blocks 111 can limit the fixing seat 11 on the sliding rail 12, so that the fixing seat 11 can only move along the length direction of the sliding rail 12.

It will be understood that the apparatus further comprises a distance measuring member 7, the distance measuring member 7 being arranged on the horizontal slide 22, the measuring direction of the distance measuring member 7 being directed towards the inspection platform 1 in the third direction Z. The height of the upper surface of the product 100 can be detected by the distance measuring member 7 so that the movement of the elevating slider 31 in the third direction Z does not cause the magnetic flux detecting member 4 to strike the product 100. Wherein, the distance measuring part 7 is a laser ranging module.

Preferably, when the lifting slide block 31 is lifted to the limit end away from the detection platform 1, the distance from the measuring end of the distance measuring piece 7 to the detection platform 1 is the same as the distance from the magnetic flux detecting piece 4 to the detection platform 1. That is, the measuring end of the distance measuring part 7 is at the same height as the magnetic flux detecting part 4, and the measured value directly reflects the distance between the magnetic flux detecting part 4 and the product 100, so that the method is more intuitive. When an operator is ready to detect the product 100, the distance between the distance measuring part 7 and the upper surface of the product 100 is the distance between the magnetic flux detecting part 4 and the upper surface of the product 100, and the operator can select the downward moving distance of the lifting slider 31 according to the value.

Preferably, the device further comprises a display screen 8, and the display screen 8 is in communication connection with the magnetic flux detecting member 4. The display screen 8 can reflect the curve of the magnetic flux changing along with the change of the distance in a rectangular coordinate system. Through the display screen 8, an operator can observe the change of the magnetic flux in the scanning process at any time to detect the position of the magnet 104.

Preferably, the magnetic flux detecting member 4 is a hall element, and the specific structure and operation principle thereof are conventional in the art and will not be described herein.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
