[0035] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0036] In this disclosure, references Figure 3 As shown, the X direction in the figure is the first direction, the Y direction is the second direction, and the Z direction is the third direction. Unless otherwise stated, "inner" and "outer" refer to the interior and exterior of the corresponding component outline; "far" and "near" refer to the distance of the corresponding component relative to another component in spatial position. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0037] The inventors discovered through research that in related technologies, workers use a simple handheld Tesla meter to test the magnetic polarity of assembled products (such as circuit breakers). However, this manual operation is tedious, inefficient, and susceptible to human factors (such as the worker's testing experience and mental state during testing), which can lead to misjudgments.

[0038] To solve the above technical problems, refer to Figures 1 to 5 As shown, this disclosure provides a detection device 10, including a body 1, a detection structure 2, and a positioning structure 3. The body 1 includes a platform 11. The detection structure 2 is connected to the body 1 and located on a first side 111 of the platform 11, and includes a magnetic pole detection element 21. The positioning structure 3 is connected to the platform 11 and located on a second side 112 of the platform 11 opposite to the first side 111. The positioning structure 3 is used to position the product to be tested 20. The platform 11 has a detection channel 113 that penetrates the first side 111 and the second side 112 of the platform 11 for the magnetic pole detection element 21 to detect the magnetic polarity of the product to be tested 20.

[0039] Through the above technical solution, the positioning structure 3 is suitable for positioning the product under test 20 so that the magnetic pole detection component 21 can detect the magnetic polarity of the product under test 20, reduce the influence of human factors during the detection process, and improve the accuracy of magnetic polarity detection. In addition, the positioning structure 3 and the detection structure 2 are respectively set on opposite sides of the platform 11, which facilitates the integrated installation of the detection structure 2 and improves the detection stability of the magnetic pole detection component 21. For example, the magnetic pole detection component 21 can be connected to the platform 11, which can also improve the accuracy of magnetic polarity detection. In addition, by separating the positioning structure 3 and the detection structure 2 through the platform 11, the magnetic pole detection component 21 detects the magnetic polarity of the product under test 20 through the detection channel 113 set on the platform 11, which can reduce the possibility of accidental collision between the product under test 20 and the magnetic pole detection component 21, so as to protect the magnetic pole detection component 21.

[0040] For example, the magnetic pole detection element 21 can be connected to the platform 11. Therefore, integrating the magnetic pole detection element 21 and the positioning structure 3 into the platform 11 can provide a basis for automated inspection. For example, a robot can be set on the platform 11 to place the product to be tested 20 on or remove it from the positioning structure 3, thereby simplifying manual work and improving inspection efficiency.

[0041] Among them, the magnetic pole detection device 21 can be a Hall effect probe, which is equipped with a Hall sensor inside. It converts the physical quantity of the magnetic field of the product under test 20 into an electrical signal through the Hall effect, and determines the magnetic polarity of the product under test 20 through the electrical signal.

[0042] In some embodiments, reference Figures 1 to 4 As shown, the platform 11 can be arranged such that the second side 112 is above the first side 111, so that the magnetic pole detection element 21 can detect the magnetic polarity of the product under test 20 from bottom to top. For example, the platform 11 can be arranged horizontally or approximately horizontally, so that the product under test 20 can be placed on the positioning structure 3 by its own weight and positioned by the positioning structure 3.

[0043] It is understood that in some other possible embodiments not shown in the accompanying drawings, the platform 11 may also be arranged such that the first side 111 and the second side 112 are arranged horizontally. For example, the platform 11 may be arranged vertically or approximately vertically. In this case, the positioning structure 3 may be disposed below the product under test 20 to position and support the product under test, or a fixing structure may be disposed to fix the product under test 20 to the positioning structure 3. This disclosure is not limited thereto.

[0044] In some embodiments, reference Figures 1 to 3As shown, the positioning structure 3 and / or the platform 11 may have multiple support parts, which are configured to support different products to be tested 20, so that different products can be tested by magnetic polarity detection element 21, thereby improving the applicability of the testing device 10.

[0045] For example, the product under test 20 can be a circuit breaker. It is known that a magnet is typically installed in a circuit breaker for arc extinguishing. The magnet is installed inside the circuit breaker housing and near the connection side where a stop is provided. Therefore, the magnetic pole detection element 21 is adapted to be close to this connection side to detect the magnetic pole direction of the magnet. Thus, the circuit breaker can be placed above the platform 11 and near the second side 112, where the connection side of the circuit breaker housing is opposite to the second side 112 of the platform 11, and the internal magnet is close to the detection channel 113 to facilitate detection by the magnetic pole detection element 21. For example, the positioning structure 3 and / or the platform 11 can contact the connection side to support the circuit breaker.

[0046] It should be noted that during the assembly of the circuit breaker, the magnet is assembled before the stop. Therefore, when the magnetic pole direction of the magnet inside the circuit breaker housing is detected, the connection side of the circuit breaker housing may be partially concave because the stop has not yet been installed. At this time, the circuit breaker will tilt because the positioning structure 3 and / or the platform 11 contact the connection side to support the circuit breaker. The magnetic field direction of the internal magnet will change accordingly, affecting the detection of the magnetic pole direction of the magnet by the magnetic pole detection component 21.

[0047] Taking the second side 112 of the aforementioned platform 11 located above the first side 111 as an example, the platform 11 can be arranged horizontally. At this time, the connection side of the circuit breaker housing contacts the second side 112 of the platform 11 and is placed on the second side 112 of the platform 11 at an angle. The direction of the magnetic field of the internal magnet changes accordingly. When the magnetic pole detection element 21 approaches the connection side through the detection channel 113, for example, the magnetic pole detection element 21 is the aforementioned Hall probe, the current direction in the Hall probe is not perpendicular or approximately perpendicular to the magnetic field direction of the magnet (within a reasonable deviation range), thus affecting the accuracy of detecting the magnetic pole direction of the magnet.

[0048] Therefore, it can be understood that the support part can support the product under test 20 from bottom to top, such as the connection side of the circuit breaker housing, so as to change the direction of the magnetic field of the magnet. The direction of the current in the Hall probe is perpendicular or approximately perpendicular to the direction of the magnetic field of the magnet, so as to improve the accuracy of detecting the direction of the magnetic pole of the magnet.

[0049] In some embodiments, reference Figure 3As shown, the multiple support portions may include a first support portion 4 and a second support portion 5. The first support portion 4 supports a first type of product under test 201, and the second support portion 5 supports a second type of product under test 202, or the second support portion 5 and the first support portion 4 jointly support the second type of product under test 202. In this way, the magnetic field direction of both the first type of product under test 201 and the second type of product under test 202 is suitable for the magnetic pole detection element 21 to detect the magnetic pole direction.

[0050] It is understood that, for example, the first type of test product 201 and the second type of test product 202 can be a first type of circuit breaker and a second type of circuit breaker, respectively. The connection side configuration of the first type of circuit breaker and the connection side configuration of the second type of circuit breaker are different. Therefore, by providing the first support part 4 and the second support part 5, the first type of circuit breaker or the second type of circuit breaker can be adaptively supported to adjust the magnetic field direction of the magnets of the first type of circuit breaker and the second type of circuit breaker.

[0051] Taking the first type of test product 201 and the second type of test product 202 as examples, the first type of circuit breaker and the second type of circuit breaker are respectively. When the magnetic pole direction of the internal magnet is detected, the first type of circuit breaker and the second type of circuit breaker do not have a stopper installed. As a result, the surface configuration of the connection side of the housing of the first type of circuit breaker is different from that of the second type of circuit breaker. The surface of the connection side of the housing of the first type of circuit breaker is flat or approximately flat, while the surface of the connection side of the housing of the second type of circuit breaker is partially concave.

[0052] For example, when the first type of circuit breaker is not equipped with a stop, the connecting side of the housing is placed against the second side 112 of the platform 11. At this time, the magnetic field direction of the magnet is suitable for the magnetic pole detection element 21 to detect the magnetic pole direction. (Refer to...) Figure 3 As shown, the platform 11 may have a first support surface 41, which forms a first support portion 4 and is disposed on the second side 112 of the platform 11. At this time, at least a portion of the connection side of the first type of circuit breaker housing can be placed on the first support surface 41, and then the magnetic pole direction of the magnet is detected by the magnetic pole detection element 21.

[0053] For example, when the stopper is not installed, the connecting side of the second type of circuit breaker is recessed, and the connecting side of the casing is placed against the second side 112 of the platform 11. At this time, the magnetic field direction of the magnet is not suitable for the magnetic pole detection element 21 to detect the magnetic pole direction. For example, the magnetic pole detection element 21 is the Hall probe mentioned above, and the current direction in the Hall probe is not perpendicular or approximately perpendicular to the magnetic field direction of the magnet. Figure 3As shown, the positioning structure 3 may include a positioning plate 31, which is disposed on the second side 112 of the platform 11. The positioning plate 31 has a second support surface 51, which forms a second support part 5. The first support surface 41 and the second support surface 51 are used to jointly support the second type of product to be tested 202. The second support surface 51 is higher than the first support surface 41.

[0054] In this way, the connection side of the second type of circuit breaker housing is placed on the first support surface 41 and the second support surface 51, that is, at least a portion of the concave portion is placed on the second support surface 51, and at least a portion of the remaining portion is placed on the first support surface 41, so that the current direction in the Hall probe is perpendicular or approximately perpendicular to the magnetic field direction of the magnet, which facilitates the detection of the magnetic pole direction of the magnet.

[0055] It is understood that in some other possible alternative embodiments, the support portion may also include a connector formed on the positioning structure 3, which can be inserted into, for example, a threaded hole formed on the product under test 20, to support the product under test 20, thereby adjusting the magnetic field direction of the product under test 20 so that the magnetic pole detection element 21 can detect the magnetic pole direction of the product under test 20.

[0056] In some embodiments, reference Figures 1 to 3 As shown, the first support surface 41 can extend along the first direction to support a plurality of first-type test products 201 arranged along the first direction, and / or the second support surface 51 can extend along the first direction to support a plurality of second-type test products 202 arranged along the first direction. This improves the detection efficiency of the magnetic pole orientation of the test product 20.

[0057] Understandably, for example, multiple products to be tested 20 can be arranged first, and then the magnetic pole detectors 21 can be used to detect the multiple products to be tested 20. For example, the detection efficiency can be improved by setting multiple magnetic pole detectors 21 to detect multiple products to be tested 20 simultaneously, wherein the number of magnetic pole detectors 21 can be equal to the number of products to be tested 20. Alternatively, one or more magnetic pole detectors 21 can be set to detect a portion of the multiple products to be tested 20, wherein the number of magnetic pole detectors 21 can be less than the number of products to be tested 20. In this way, when the magnetic pole detectors 21 are detecting another portion of the products to be tested 20, the already detected products to be tested can be replaced, so that the magnetic pole detectors 21 can continuously detect, thereby improving the detection efficiency.

[0058] In this device, the multiple test products 20 can all be either first-type test products 201 or second-type test products 202. Alternatively, the multiple test products 20 can be one or more first-type test products 201 and one or more second-type test products 202. That is, the first-type test products 201 and the second-type test products 202 can be placed simultaneously in the accommodating space formed by the positioning structure 3 and the platform 11 (described below). In this way, the detection device 10 can perform magnetic polarity detection on only the first-type test product 201 or the second-type test product 202, or it can perform magnetic polarity detection on both the first-type test product 201 and the second-type test product 202 simultaneously. This disclosure does not specifically limit the specific application of this method.

[0059] In some embodiments, reference Figure 3 As shown, the positioning structure 3 may include a first baffle 32, a second baffle 33, and a third baffle 34. The first baffle 32 and the positioning plate 31 are arranged at intervals along the second direction and both extend along the first direction. The second baffle 33 and the third baffle 34 are arranged at intervals along the first direction and both extend along the second direction. The first baffle 32, the second baffle 33, the third baffle 34, the positioning plate 31, and the platform 11 together form a receiving space for placing the product under test 20. The first direction is perpendicular to the second direction to facilitate positioning the magnetic field direction of the product under test 20.

[0060] In this way, the product under test 20 can be positioned in the second direction by the first baffle 32, and the product under test 20 can be positioned and limited in the first direction by the second baffle 33 and the third baffle 34. The product under test 20 is placed in the accommodating space to improve the stability of the product under test 20 during testing.

[0061] It is understood that in some other embodiments, only one of the second baffle 33 and the third baffle 34 may be provided to position the product under test 20 in the first direction. In addition, the positioning plate 31 may also be provided with a limiting surface to cooperate with the first baffle 32 to limit the product under test 20 in the second direction. This disclosure is not limited thereto.

[0062] Therefore, multiple products under test 20 can be arranged along the first direction, and the detection channel 113 can extend along the first direction. The magnetic pole detection element 21 can include a magnetic polarity probe 211. The detection structure 2 can also include a driving element 23, which drives the magnetic polarity probe 211 to move along the first direction, so as to be suitable for detecting multiple products under test 20 arranged along the first direction.

[0063] The number of magnetic polarity probes 211 can be set to one, and the driving element 23 can drive one magnetic polarity probe 211 to move along the first direction. Alternatively, the number of magnetic polarity probes 211 can also be set to multiple, with multiple magnetic polarity probes 211 arranged adjacently or at intervals along the first direction for simultaneous detection of multiple products 20 to be tested.

[0064] In some embodiments, reference Figures 3 to 5 As shown, the driving element 23 can move the magnetic polarity probe 211 along a third direction to move closer to or further away from the detection channel 113. Thus, for example, multiple products under test 20 can be first placed in the receiving space, and then the driving element 23 can move the magnetic polarity probe 211 along a third direction to move closer to the detection channel 113, facilitating magnetic polarity detection of the products under test 20. When removing the product under test 20 from or placing it in the receiving space, the driving element 23 moves the magnetic polarity probe 211 along a third direction to move further away from the detection channel 113, reducing the possibility of the product under test 20 accidentally touching and damaging the magnetic polarity probe 211, thus affecting the magnetic polarity detection. The third direction is perpendicular to the first and second directions.

[0065] It is understood that the driving element 23 can drive the magnetic polarity probe 211 to move in another direction, so as to move away from or closer to the detection channel 113, but this disclosure is not limited thereto.

[0066] In some embodiments, reference Figure 4 and Figure 5 As shown, the driving unit 23 may include a first driving part 231 and a second driving part 232, wherein the magnetic polarity probe 211 is connected to the output end of the first driving part 231, the first driving part 231 is connected to the output end of the second driving part 232, one of the first driving part 231 and the second driving part 232 is adapted to drive the magnetic polarity probe 211 to move along a second direction, and the other is adapted to drive the magnetic polarity probe 211 to move along a third direction.

[0067] This disclosure exemplarily configures the first drive unit 231 to drive the magnetic polarity probe 211 to move along a third direction, and the second drive unit 232 to drive the first drive unit 231 and the magnetic polarity probe 211 to move along a first direction. It is understood that the first drive unit 231 and the second drive unit 232 can be constructed in any suitable manner. For example, the first drive unit 231 may include a cylinder, with the magnetic polarity probe 211 connected to the output end of the cylinder, the output end of which is adapted to drive the magnetic polarity probe 211 to move along a third direction. The second drive unit 232 may include an electric cylinder, with the cylinder connected to the output end of the electric cylinder, the output end of which is adapted to drive the cylinder and the magnetic polarity probe 211 to move along the first direction.

[0068] For example, the number of magnetic polarity probes 211 is set to two arranged at intervals along the first direction. The two magnetic polarity probes 211 are connected to the output end of the cylinder via a mounting base, and the fixed end of the cylinder is connected to the drive slider of the electric cylinder via a bracket. The magnetic polarity probes 211 are detachably connected to the mounting base via, for example, a pressure plate threaded to the mounting base, to facilitate maintenance and replacement.

[0069] In some embodiments, reference Figure 4 As shown, the detection structure 2 may also include a teslameter host 22 used in conjunction with the magnetic polarity probe 211. The teslameter host 22 corresponds one-to-one with the magnetic polarity probe 211. The teslameter host 22 can interpret the electrical signal output by the magnetic polarity probe 211 to display the magnetic field strength and indicate the polarity of the magnetic field relative to the magnetic polarity probe 211 by using a positive (+) or negative (-) sign. This enables the detection of the polarity of the magnetic field of the product under test 20, such as the detection of the magnetic polarity of the magnet installed in the circuit breaker.

[0070] In some embodiments, reference Figure 1 and Figure 5 As shown, the main body 1 may include a cabinet 12, with a platform 11 formed or installed on the top of the cabinet 12. An installation space is formed inside the cabinet 12, and the detection structure 2 is installed in the installation space. Thus, the cabinet 12 protects the detection structure 2, ensuring its integrity, and also reduces external magnetic field interference, improving the accuracy of detecting the polarity of the magnetic field of the product under test 20. The drive unit 23 can be connected to the first side 111 of the platform 11, and the Tesla meter main unit 22 can be installed at the bottom of the cabinet 12.

[0071] In some embodiments, reference Figure 1 and Figure 5 As shown, the detection device 10 may also include a control circuit module 6 and a display screen 7. The control circuit module 6 may be installed in the installation space. The control circuit module 6 is connected to the Tesla meter host 22 and the display screen 7. The cabinet 12 can protect the control circuit module 6 to ensure the normal operation of the detection process.

[0072] In addition, the display screen 7 can be mounted on the platform 11, so that the staff can observe whether the polarity of the magnetic field of the product under test 20 meets the assembly requirements through the display screen 7. The display screen 7 can also be adapted to display the polarity of the magnetic field of the product under test 20, so as to compare with the results of whether the assembly requirements are met, thereby improving the accuracy of the test.

[0073] It is understood that a protective element 8 is also provided on the cabinet 12 to protect the detection structure 2, control circuit module 6, and display screen 7 from power failure. For example, the protective element 8 can be a residual current circuit breaker (RCCB), which can also be used to open and close the electrical path formed by the detection structure 2, control circuit module 6, and display screen 7. This disclosure is not limited thereto.

[0074] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0075] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0076] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
