[0022] For the convenience of explanation, Figure 1 and Figure 2 The magnetic body 51 and the Hall sensor 2 are shown in perspective. In the actual product, the magnetic body 51 and the Hall sensor 2 are respectively arranged inside the support plate 5 and the detection base 1, and are not visible from the outside.

[0023] Reference Figure 1-3 The embodiment of the utility model provides a magnetic pole detection jig for detecting the magnetic pole of the support plate 5, which includes: a detection base 1, a Hall sensor 2, an indicator, and a power supply 4; wherein, a product positioning groove 11 is provided on the detection base 1, which can be used to place and fix the support plate 5; the Hall sensor 2 is arranged on the side wall of the product positioning groove 11, and corresponds to the position of the magnetic body 51 on the side of the support plate 5, and can be used to detect the magnetic pole of the magnetic body 51, the indicator is connected to the Hall sensor 2 in communication, and can output the detection result of the Hall sensor 2, and the power supply 4 is used to power the Hall sensor 2 and the indicator to ensure the normal operation of the Hall sensor 2 and the indicator. wherein, the detection direction of the Hall sensor 2 is perpendicular to the side of the support plate 5, which can ensure the accuracy of the detection.

[0024] Please refer to Figure 3 The connection circuit between the power supply 4, the Hall sensor 2 and the indicator is a conventional detection circuit, and the utility model does not improve the detection circuit. In this embodiment, six magnetic bodies 51 are provided on the side of the support plate 5, and the number of the Hall sensors 2 and the indicators corresponds to the number of the magnetic bodies 51, wherein a group of Hall sensors 2 and indicators corresponds to one detection circuit, and the magnetic poles of each magnetic body 51 can be detected separately, and the magnetic body 51 with inaccurate magnetic pole direction can be clearly displayed, which is convenient for the repair of the support plate 5.

[0025] In this embodiment, a product positioning groove 11 is opened on the detection base 1 to place and fix the support plate 5, and then a Hall sensor 2 for detecting the magnetic pole direction of the magnetic body 51 on the side of the support plate 5 is set on the side wall of the product positioning groove 11, and the detection effect is output through an indicator, wherein the detection direction of the Hall sensor 2 is perpendicular to the side of the support plate 5, which can ensure the accuracy of the detection, that is, the use of the magnetic pole detection fixture of the utility model can quickly and efficiently complete the detection of whether the magnetic pole direction of the magnetic body 51 on the side of the support plate 5 is correct, which can greatly improve the efficiency of the detection.

[0026] Specifically, the indicator includes an indicator light 31 and a buzzer (not shown in the figure), wherein when the detected magnetic pole direction is correct, the indicator light 31 emits a first color light; when the detected magnetic pole direction is wrong, the indicator light 31 emits a second color light or does not emit light; wherein the first color and the second color are different. In this embodiment, the first color light is green light, and the second color light is red light; further, when the detection structure is incorrect, the buzzer will sound to remind the magnetic body 51 that the magnetic pole direction is incorrect, which can improve the indication effect and prevent unqualified products from flowing out of the market due to workers being tired from working for a long time or being careless.

[0027] The indicator light 31 and the buzzer are both arranged on one side of the Hall sensor 2 .

[0028] For further information, please refer to Figure 1 The base is also provided with a first material removal avoidance groove 12, a second material removal avoidance groove 13 and a third material removal avoidance groove 14 which are all connected to the product positioning groove 11. The first material removal avoidance groove 12 and the second material removal avoidance groove 13 are symmetrically arranged on two sides adjacent to the Hall sensor 2, and the third material removal avoidance groove 14 is arranged on the side opposite to the Hall sensor 2. In this embodiment, the size and shape of the product positioning groove 11 correspond to the size and shape of the support plate 5. When the support plate 5 is placed into the product positioning groove 11, it is difficult for workers to take out the support plate 5 that has been tested. Now, by adding the first material removal avoidance groove 12, the second material removal avoidance groove 13 and the third material removal avoidance groove 14, it is convenient for the factory to take out the support plate 5 from all directions, which greatly improves the efficiency of taking out the support plate 5, and then improves the efficiency of testing.

[0029] Furthermore, the depth of the product positioning groove 11 is the same as the height of the support plate 5, and the depths of the first material picking avoidance groove 12, the second material picking avoidance groove 13 and the third material picking avoidance groove 14 are the same, which are all 0.5 cm deeper than the depth of the product positioning groove 11. Since the thickness of the support plate 5 is relatively small, when the depths of the first material picking avoidance groove 12, the second material picking avoidance groove 13 and the third material picking avoidance groove 14 are the same as the depth of the product positioning groove 11, the contact surface between the worker's hand and the support plate 5 is too small, and it is not easy to remove the support plate 5. In this embodiment, by deepening the depths of the first material picking avoidance groove 12, the second material picking avoidance groove 13 and the third material picking avoidance groove 14, it is convenient for the worker to partially extend his hand into the lower side of the support plate 5, thereby increasing the contact area between the hand and the support plate (the side surface and the partial bottom surface under the side surface), and facilitating the removal of the support plate 5.

[0030] Furthermore, the width of the first material picking avoidance slot 12 is 1-1.5cm, and the length is 4-5cm. The first material picking avoidance slot 12 and the second material picking avoidance slot 13 are of the same shape and size. The width of the third material picking avoidance slot 14 is 1-1.5cm, and the length is 4-8cm. Among them, limiting the width of the first material picking avoidance slot 12 to 1-1.5cm can facilitate fingers to enter the first material picking avoidance slot 12, and limiting the length to 4-5cm can facilitate multiple fingers to enter the first material picking avoidance slot 12. Multiple fingers can simultaneously support the support plate 5 to ensure the efficiency of taking out the support plate 5.

[0031] Furthermore, the four corners of the product positioning groove 11 correspond to the four corners of the support plate 5. By limiting the relationship between the four corners of the product positioning groove 11 and the support plate 5, the positioning effect of the product positioning groove 11 can be ensured. In this embodiment, the four corners of the support plate 5 are all rounded, and similarly, the four corners of the product positioning groove 11 can be set as rounded, which can facilitate the processing of the product positioning groove 11.

[0032] Furthermore, the detection base 1 is also provided with a foolproof protrusion 15 corresponding to the position of the camera hole 52 of the support plate 5. In this embodiment, the support plate 5 has a direction, and the directions of the support plate 5 and the magnetic body 51 may be opposite. Now, by adding the foolproof protrusion 15 corresponding to the position of the camera hole 52, the accuracy of the position of the support plate 5 can be ensured, and then the accuracy of the magnetic detection of the magnetic body 51 can be ensured.

[0033] Furthermore, the detection base 1 includes a metal base 16 at the bottom and a silicone base 17 arranged above the metal base 16, the product positioning groove 11 is opened on the silicone base 17, and the Hall sensor 2 and the indicator are both arranged on the silicone base 17. By setting the detection base 1 as a combination of the metal base 16 and the silicone base 17, the metal base 16 can provide a larger weight to improve the stability of the detection base 1, and the silicone base 17 can prevent the detection base 1 from colliding with the support plate 5 to cause damage to the support plate 5, thereby improving the yield rate of the detected products.

[0034] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
