Description of the Invention: [Technical Field] The present invention relates to a measurement technique, and more particularly to a measurement system for measuring a magnetic member. [Prior Art] At present, Voice Coil Motor (VCM) is widely used as a driving device in electronic products such as digital cameras, mobile phones, digital video cameras, etc. (see Design of a voice coil motor used in the focusing system of a digital video camera » Magnetics, IEEE Transactions on Volume 41, Issue 10, Oct. 2005 Page(s): 3979 - 3981). The voice coil motor includes a four-sided holder for the magnetic member, and the magnetic member is usually fastened to the holder by gluing. When the glue is glued, the displacement element between the magnetic member and the holder is easily caused by the manual operation, and the installation position of the magnetic member is difficult to meet the design requirements. It is common to use a distance meter to measure the mounting position between the magnetic member and the holder to meet the design requirements. " However, since the measuring distance of the distance meter will contact the magnetic member and the fixing frame, it is easy to damage the magnetic member and the fixing frame, and the measuring position of the distance meter needs to be calibrated each time the distance meter is used, which is time-consuming and labor-intensive. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a measuring system that avoids contact with a magnetic member and a holder while measuring and reduces man hours. A measuring system for measuring whether a position of a plurality of magnetic members on a fixed frame is correct. The measurement system includes a motor, a positioning 201000855 rack, a magnetoresistive sensing component, and a comparison unit. The motor has a rotating shaft. The positioning frame is fixed on the rotating shaft, and the fixing frame is sleeved on the positioning frame. The magnetoresistive sensing element is for sensing a magnetic flux of a magnetic member corresponding to the magnetoresistive sensing element. Presetting a standard magnetic flux in the comparing unit, the comparing unit is configured to determine whether the magnetic flux sensed by the magnetoresistive sensing element is the same as the standard magnetic flux to determine whether the magnetic component is disposed on the fixing frame The correct location. Compared with the prior art, the measuring system uses the magnetoresistive sensing element to sense the magnetic flux of the magnetic member to determine whether the magnetic member is disposed at the correct position on the fixing frame, thereby avoiding contact with the magnetic member during measurement of the measuring system. And the fixing frame, and the magnetoresistive sensing component can automatically measure the magnetic parts in turn in accordance with the rotation of the rotating shaft of the motor, thereby reducing the working time. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Please refer to FIG. 1, which is a measurement system 100 according to an embodiment of the present invention. The measurement system 100 is used to measure whether the plurality of magnetic members 14 are disposed at a correct position on a mount 10. The measuring system 100 includes a motor 20, a support frame 30, a positioning frame 40, a magnetoresistive sensing component 60, a comparison unit 70, and a signal receiving display unit 80. The magnetoresistive sensing element 60 is disposed on the support frame 30. The motor 20 has a rotating shaft 28. The positioning frame 40 is fixed on the rotating shaft 22 of the motor 20 and rotates the mounting frame 10 as the rotating shaft 28 rotates, so that the magnetic members 14 are correspondingly measured by the magnetoresistive sensing element 60. 7 201000855 In the present embodiment, the shape of the fixing frame is square, and includes four side walls 12, and each side wall 12 is correspondingly provided with a magnetic member 14. Each of the magnetic members 14 is generally fixed to the corresponding position on the four sides of the holder 10 by means of a bonding method. The motor 20 includes a body 22 and a shaft cover 24 disposed on one side of the body 22 in the axial direction of the holder 10. The shaft cover 24 has a bearing surface 26 and a rotating shaft 28, and the rotating shaft 28 is disposed on one side of the bearing surface 26 of the shaft cover 24 near one side of the fixing frame 10. The magnetoresistive sensing element 60 is disposed on the support frame 30. It can be understood that in order to make the magnetoresistive sensing element 60 set at different positions according to different measurement requirements, the support frame 30 is set to be height-adjustable to change the position of the magnetoresistive sensing element 60 by adjusting the height of the support frame 30. . In this embodiment, the support frame 30 includes a base 32, a support rod 34 and a moving table 36. The base 32 is disposed on one side of the motor 20, and the support rod 34 is disposed on the base 32 in a direction close to the fixed frame 10, and the magnetoresistive sensing element 60 is disposed on the moving table 36. Four support holes 38 are defined in the support bar 34. The mobile table 36 includes a handle 39 that can be received in the receiving hole 38. The handle 39 is engaged with the receiving hole 38 to facilitate the handle 39 to change the height of the moving table 36 by matching with the different receiving holes 38, thereby changing the position of the magnetoresistive sensing element 60. The shape of the positioning frame 40 corresponds to the shape of the fixing frame 10 to facilitate the cooperation of the fixing frame 10 with the positioning frame 40. In the present embodiment, the shape of the positioning frame 40 is square. In the embodiment, the bottom of the positioning frame 40 defines a through hole (not shown) for receiving the rotating shaft 28 of the motor 20 to cooperate with the motor 20 to rotate the motor 40, and the motor 20 drives the positioning frame 40 by the rotation of the rotating shaft 28. Turn 201000855. Move. The fixing frame 10 is sleeved on one end of the positioning frame 40 away from the motor 20, and the fixing frame 10 and the positioning frame 40 are cooperatively fastened. The rotation of the positioning frame 40 drives the rotation of the fixing frame 10, so that the magnetic members 14 of each side wall 12 of the fixing frame 10 are sequentially rotated. In the present embodiment, the fixing frame 10 and the positioning frame 40 are fastened in a snapping manner to facilitate replacement of the magnetic member 14 to be detected. The magnetoresistive sensing element 60 is disposed on the moving stage 36 of the support frame 30 for sensing the magnetic flux of the magnetic member 14 of the holder 10. The magnetoresistive sensing element 60 is an element that senses the magnetic flux of the magnetic member 14 in a certain distance range when the magnetic member 14 is disposed in an arbitrary manner such as vertical, parallel, or the like. The comparison unit 70 presets a standard magnetic flux, and the comparison unit 70 compares the magnetic flux sensed by the magnetoresistive sensing element 60 with the standard magnetic flux to determine whether the magnetic member 14 is disposed at a corresponding position of the holder 10. If the position of the magnetic member 14 mounted on the holder 10 meets the design requirements, the magnetoresistive sensing element 60 senses the magnetic flux of the magnetic member 14, that is, the standard magnetic flux preset in the comparison unit 70. Therefore, the comparison unit % 70 can determine whether the position of the magnetic member 14 on the holder 10 meets the design requirements by comparing the magnetic flux of the magnetic member 14 sensed by the magnetoresistive sensing element 60 with the preset standard magnetic flux. If the magnetic flux sensed by the magnetoresistive sensing element 60 is the same as the standard magnetic flux, the position of the magnetic member 14 on the mounting frame 10 meets the design requirements, and the comparing unit 70 outputs a corresponding indication signal according to the comparison result. If the magnetic flux sensed by the magnetoresistive sensing element 60 is different from the standard magnetic flux, the position of the magnetic member 14 on the mounting frame 10 does not meet the design requirement, and the comparing unit 9 201000855 7 0 rotates the corresponding indication according to the comparison result. Signal. The signal receiving display unit 8G is configured to receive the information indicating that the π number of the comparison unit % is outputted to the user for viewing to determine in time whether the magnetic member 14 satisfies the design wire. If the magnetic flux of the miscellaneous component (9) is the same as the standard magnetic flux, the signal receiving the display unit 8 receives the corresponding indication signal output by the comparison unit 70 and displays H, 'the positional design requirement of the magnetic component 14 on the fixed frame 1G. . If the magnetic flux sensed by the magnetoresistive sensing element (9) is different from the standard magnetic flux, the signal receiving display unit 8 receives the corresponding indication signal output by the comparing unit 70 and displays as “〇,, the magnetic member 14 is on the fixed frame 1 The position on the cymbal does not meet the design requirements. The magnetoresistive sensing element 60 measures a magnetic member 14, and the shaft 22 of the motor 2 rotates by an angle in a clockwise or counterclockwise direction to cause the magnetoresistive sensing element (9) to sense the holder. The magnetic flux of the magnetic member 14 on the other side wall 12 of the ίο. In the present embodiment, the angle of rotation of the rotating shaft 28 of the motor 2G in the counterclockwise direction is 90 degrees. It can be understood that the angle of rotation of the rotating shaft 28 is fixed by the fixing frame 1 The shape and the number of magnetic members 14 are different to ensure that each magnetic member 14 can be measured by the magnetoresistive sensing element 6 。.

The angle control signal is rotated by the driving motor % at a pre-angle. In the embodiment, the preset driving direction is counterclockwise in the driving unit_ and the driving angle is 9 〇纟. The measured magnetic member 14 201000855 is on the fixed frame ίο The position of the magnetic component 14 is measured, and the comparison unit 70 outputs a corresponding indication signal to cause the control unit το 90a to drive the rotation axis of the drive motor 20 to rotate counterclockwise by 90 degrees. The magnetoresistive sensing element 6 〇 senses the magnetic flux of the magnetic member 14. The control unit 90a sequentially activates the rotation of the driving unit 9〇b to drive the motor 2〇 to cause the magnetoresistive sensing element 6〇 to sequentially measure the four magnetic members Η In the actual palladium mode, the first magnetic piece in the counterclockwise direction, that is, the magnetic member 14 which is oppositely disposed, is fixed to the holder: not satisfied, and the tenth requirement, the second magnetic member 14 and the fourth magnetic The position of the piece on the fixing frame 10 satisfies the design requirement, and the signal receives the display unit rib. According to the indication signal output by the comparison unit 70, "〇,,, y", 1 can be displayed in sequence, and the signal receiving is displayed.
