Description

Technical Field

[0001] The present invention relates to the technical field of sensor fault detection, and specifically to a Hall current sensor fault detection device. Background Art

[0002] A Hall current sensor is an electronic device based on the Hall effect principle, which non - contact measures current by detecting the change of the magnetic field around a conductor. In the mass production process of sensors, the quality inspection stage is a crucial link. In the quality inspection process, the sensor must establish a stable electrical connection with the detection equipment to accurately measure and record its various performance indicators.

[0003] The instability of this connection may bring a series of potential risks. Notably, when the connection is poor, the electrical connection point may generate arcs or sparks due to poor contact, which will not only damage the internal electronic components of the sensor, but also trigger leakage and signal transmission interruption due to the instability of the electrical connection, affecting the detection accuracy. The leakage problem will not only interfere with the normal operation of the sensor, but also pose potential safety hazards to surrounding equipment or personnel. In addition, the instability of the connection may also lead to deviation in the quality inspection results. Since the signal transmission may be interrupted or distorted, the detection equipment may not be able to accurately measure and record the performance indicators of the sensor. In view of this, in the current quality inspection stage of the sensor mass production process, mainly two methods are relied on to ensure the connection between the sensor and the detection equipment. However, both of these methods have certain limitations. The first method focuses on manual operation. Although it can ensure the accuracy of the connection, when dealing with live sensors, the operator will face the safety hazard of electric shock. The second method tends to be mechanized operation. Although it can effectively reduce the risk of electric shock, there is a problem of unstable connection, affecting the accuracy of quality inspection.

[0004] Therefore, we propose a Hall current sensor fault detection device. Summary of the Invention

[0016] The present invention has the following beneficial effects: 1. The Hall current sensor fault detection device effectively solves the problem of unstable sensor connection in traditional mechanical detection through the coordinated design of the detection device and the fixed component. In this solution, the transportation equipment drives the telescopic inner rod to periodically press down the detection port, and the synchronous transportation with the No. 1 conveyor belt realizes the positioning detection of the sensor. The fixed component adopts a combination of an extrusion shaft and a rubber pad. When the telescopic inner rod is pressed down, the rack drives the gear block to rotate, driving the connecting rod to make the extrusion fixed block squeeze the sensor obliquely upward. This design not only firmly embeds the sensor into the detection port through friction, but also offsets gravity through the upward component force to prevent the sensor from sliding down. Compared with manual operation, this mechanical structure realizes batch automated detection, and the connection stability is significantly improved, avoiding detection errors caused by poor contact, and ensuring the efficiency and accuracy of the quality inspection process.

[0017] 2. The Hall current sensor fault detection device realizes the safety detection process of "connect first, then power on" through the innovative design of the power-on component and the drive component. When the L-shaped connection block slides, the driving folding rod pushes the abutting triangle block, so that the No. 1 pressure plate and the No. 2 pressure plate move in stages: the No. 2 power-on rod first contacts the sensor pin, and then the No. 1 power-on rod connects with the power-on block in the arc block. This step-by-step connection ensures that the circuit is established after the physical contact is stable, fundamentally avoiding the electric sparks caused by poor contact at the moment of power-on. At the same time, the elastic buffering of the No. 1 compression spring and the No. 2 compression spring allows the power-on plate to maintain contact pressure during slight displacement and compensate for mechanical tolerances. The drive component realizes the progressive movement of the power-on plate through the cooperation of the reset spring and the inclined surface of the abutting triangle block, further reducing the risk of instantaneous current shock.

[0018] 3. The Hall current sensor fault detection device has a linkage design between the reinforcement component and the pneumatic component, which further improves the reliability of the detection process. When the first pressing plate slides upward, the pressing block in the air groove compresses the air, drives the pneumatic push rod through the pneumatic groove and the hose, and makes the limiting block insert into the tooth block gap of the extrusion shaft to lock the fixing component, further ensuring the stability of the connection between the sensor and the detection port. If the sensor is not correctly connected, the limiting block cannot be fully engaged, resulting in the first pressing plate not being in place and the circuit not being connected. This air pressure feedback mechanism forms a closed-loop control of "connection state - circuit connection": only when the sensor is stably inserted into the detection port, the pneumatic component allows power-on, thus avoiding the risk of electric leakage when not correctly connected. At the same time, the mechanical locking of the limiting block further enhances the firmness of the connection and prevents the sensor from falling off due to vibration or external force during the detection process.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In the first embodiment, this embodiment aims to facilitate the solution of the problems of unstable connection or leakage of electricity during the batch detection of the sensor body. Please refer to Figures 1 to 10 , a Hall current sensor fault detection device, including a base 1 and a detection instrument 24. A detection device 2 is installed on the base 1. The detection device 2 includes a telescopic inner rod 26. A detection port 27 is arranged at the bottom of the telescopic inner rod 26. The detection port 27 is electrically connected to the detection instrument 24. A detection sensor 210 is arranged in the detection port 27; A fixing assembly 4 for ensuring the stable connection between the detection sensor 210 and the detection port 27 is arranged at the bottom of the telescopic inner rod 26. The fixing assembly 4 includes an extrusion shaft 44. One side of the extrusion shaft 44 is connected with an extrusion fixing block 46 through a connecting rod 45. The extrusion fixing block 46 is used to lift the detection sensor 210; An energizing component 5 and a driving component 6 for preventing electric leakage are arranged inside the telescopic inner rod 26. The energizing component 5 includes a first L-shaped current-connecting plate 58 and a second L-shaped current-connecting plate 59. The driving component 6 is used to control the connection between the first L-shaped current-connecting plate 58 and the second L-shaped current-connecting plate 59.

[0032] The detection device 2 includes a transportation device 21. A transportation slider 22 is slidably connected inside the transportation device 21. A telescopic outer shell 25 is fixedly connected to the bottom of the transportation slider 22. A telescopic inner rod 26 is slidably connected inside the telescopic outer shell 25. The transportation device 21 is connected to the base 1 through a connecting frame 23. A first conveyor belt 28 and a second conveyor belt 29 are installed inside the base 1.

[0033] The detection port 27 is used to detect the detection sensor 210. The detection sensor 210 is transported by the first conveyor belt 28. After being detected, the detected detection sensor 210 is, under the action of the reinforcement component 7, transported to the second conveyor belt 29 for the faulty detection sensor 210, and the normal detection sensor 210 continues to be transported by the first conveyor belt 28.

[0034] The detection port 27 serves as a detection terminal for connecting to the detection sensor 210 and detecting the detection sensor 210 through the detection instrument 24.

[0035] Through the design of the detection device 2, the automatic batch detection of the detection sensor 210 is realized. Driven by the telescopic driving component 3, the detection port 27 at the bottom of the telescopic inner rod 26 detects the detection sensor 210 on the first conveyor belt 28 at a fixed position. After the detection is completed, the detection instrument 24 obtains the detection result of the detection sensor 210 and, according to the result, controls the pneumatic push rod 71. If the detected detection sensor 210 is faulty, the pneumatic push rod 71 continuously blows air to ensure the restriction on the fixing component 4. Then, under the movement of the transportation device 21, the faulty detection sensor 210 is transported to the second conveyor belt 29. If the detected detection sensor 210 is normal, no control is made on the pneumatic push rod 71. At this time, the detection sensor 210 will continue to be transported on the first conveyor belt 28 (in the above structure, the driving of the transportation slider 22 by the transportation device 21, the detection of the detection sensor 210 by the detection instrument 24 and the detection port 27, and the automatic control method of the detection instrument 24 for the pneumatic push rod 71 are set by a person skilled in the art to an automatic controller, such as a PLC, according to the above control logic. The specific control method is not described in detail here).

[0036] A telescopic driving assembly 3 for driving the telescopic inner rod 26 to slide in the telescopic outer shell 25 is provided in the transport equipment 21. The telescopic driving assembly 3 includes an arc block 31 installed in the transport equipment 21. A No. 1 slide groove 32 is provided in the telescopic outer shell 25. A No. 1 slide rod 33 is slidably connected in the No. 1 slide groove 32. One end of the No. 1 slide rod 33 is fixedly connected to the top of the telescopic inner rod 26. The top of the telescopic inner rod 26 is connected to the telescopic outer shell 25 through a telescopic spring 34. The other end of the No. 1 slide rod 33 extends out of the top of the transport slider 22.

[0037] The telescopic drive assembly 3 is used to control the telescopic inner rod 26 to slide in the telescopic outer shell 25. When the transport slider 22 slides to the arc block 31, the No. 1 slide bar 33 slidably connected to the transport slider 22 and the telescopic inner rod 26 contacts the arc surface of the arc block 31 and slides downward under the drive of the arc block 31 (the arc block 31 shown in the accompanying drawing is a schematic diagram. In order to ensure the detection time, the arc block 31 can be set in a long strip shape, and its specific size and position are designed according to actual needs). Therefore, the telescopic inner rod 26 fixedly connected to the No. 1 slide bar 33 slides downward synchronously. Through this design, the telescopic inner rod 26 can be driven to slide downward, and the detection port 27 can be driven to connect with the detection sensor 210. The positioning of the position between the detection port 27 and the detection sensor 210 is controlled by the transport speed of the transport slider 22 and the No. 1 conveyor belt 28 (this control method is a prior art, so this solution will not be described in detail). The arc block 31 serves as a connecting block, and an electric block is installed inside, which is used to transmit the circuit of the detection instrument 24 to the No. 1 L-shaped connecting board 58.

[0038] The fixing assembly 4 includes a mounting groove 41 provided on the side wall of the telescopic inner rod 26, a fixing shaft 42 is fixedly connected in the mounting groove 41, an outer side wall of the fixing shaft 42 is rotatably connected to an extrusion shaft 44, the extrusion shaft 44 and the fixing shaft 42 are connected via a torsion spring 43, a connecting rod 45 is fixedly connected to the outer side wall of the extrusion shaft 44, the other end of the connecting rod 45 is rotatably connected to an extrusion fixing block 46, the extrusion fixing block 46 is used to extrude the detection sensor 210, and a smooth plate 47 is arranged between the extrusion fixing block 46 and the detection sensor 210.

[0039] A tooth block 48 is fixedly connected to the side wall of the extrusion shaft 44 , and a rack 49 is meshingly connected to the tooth block 48 . The rack 49 is fixedly connected to the bottom of an L-shaped connecting block 410 , and the L-shaped connecting block 410 is slidably connected in a No. 2 slide groove 411 , and the No. 2 slide groove 411 is opened on the side wall of the telescopic inner rod 26 .

[0040] To ensure the stable connection between the detection sensor 210 and the detection port 27 during the detection process, through the design of the fixing component 4, it can be ensured that the detection sensor 210 is inserted into the detection port 27 steadily, thereby ensuring the stable connection between the detection sensor 210 and the detection port 27. When the telescopic inner rod 26 slides downward, the L-shaped connection block 410 and the rack 49 fixedly connected thereto slide downward synchronously, thereby driving the extrusion shaft 44 containing the tooth block 48 engaged with the rack 49 to rotate. By the rotation of the extrusion shaft 44, it can drive the connecting rod 45 fixedly connected to the side wall of the extrusion shaft 44 to slide inward. Since the connecting rod 45 rotates inward under the action of the extrusion shaft 44, the extrusion fixing block 46 installed at the other end of the connecting rod 45 presses the detection sensor 210 obliquely upward. Therefore, in addition to sliding inward, the detection sensor 210 is also subjected to an upward force. And because the other end of the connecting rod 45 is rotatably connected with the extrusion fixing block 46, and the connecting rod 45 is arranged at a position close to the bottom of the extrusion fixing block 46, the detection sensor 210 will be subjected to an upward force at this time. Through the design of this force, it can drive the detection sensor 210 to slide upward. The smooth plate 47 arranged on one side of the extrusion fixing block 46 can further reduce the friction between the detection sensor 210 and the smooth plate 47, thereby further ensuring that the detection sensor 210 can slide upward. At this time, the two sides of the detection sensor 210 are squeezed and subjected to an upward force, so the detection sensor 210 will not have the risk of sliding downward, thereby ensuring the stable connection between the detection sensor 210 and the detection port 27 and ensuring the stability of the detection process.

[0041] Embodiment 2. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 10 , and an energization component 5 and a driving component 6 for preventing electric leakage are arranged in the telescopic inner rod 26.

[0042] The energization component 5 includes a connection groove 53 opened in the telescopic inner rod 26. A first pressing plate 54 and a second pressing plate 55 are slidably connected in the connection groove 53. A first energization rod 52 is fixedly connected above the first pressing plate 54. The first energization rod 52 is slidably connected in a first energization groove 51. The first energization groove 51 is opened in the first sliding rod 33. A second energization rod 56 is fixedly connected to the bottom of the second pressing plate 55. The second energization rod 56 is slidably connected in a second energization groove 57. The bottom of the second energization rod 56 is used for connecting with the pin of the detection sensor 210. A first L-shaped electricity-connecting plate 58 is fixedly connected to the bottom of the first pressing plate 54, and a second L-shaped electricity-connecting plate 59 is fixedly connected to the top of the second pressing plate 55.

[0043] The driving component 6 includes a first compression spring 61 and a second compression spring 62. The first compression spring 61 is used to connect the first pressing plate 54 and the connecting groove 53, and the second compression spring 62 is used to connect the connecting groove 53 and the second pressing plate 55. The first pressing plate 54 and the second pressing plate 55 are abutted by the abutting triangular block 63.

[0044] The abutting triangular block 63 is slidably connected in the abutting chute 67. The abutting chute 67 is opened in the telescopic inner rod 26. One end of the abutting triangular block 63 is connected to the abutting chute 67 through a return spring 64. The bottom of the abutting triangular block 63 abuts against a driving folding rod 65. The driving folding rod 65 is slidably connected in the driving chute 66. The other end of the driving folding rod 65 is fixedly connected to one side of the L-shaped connecting block 410.

[0045] The designs of the energizing component 5 and the driving component 6 are used to avoid the problem of electric leakage caused by unstable connection during the connection process. When the L-shaped connecting block 410 slides upward, the driving folding rod 65 fixedly connected to the L-shaped connecting block 410 slides upward synchronously, thereby abutting against the abutting triangular block 63 and driving the abutting triangular block 63 to slide inward. Due to the inclined surface design at the other end of the abutting triangular block 63, the first pressing plate 54 and the second pressing plate 55 are respectively driven to slide upward and downward. By setting different slopes for the inclined surfaces on both sides of the abutting triangular block 63 and the first pressing plate 54 and the second pressing plate 55, the second pressing plate 55 can be driven to slide first, thereby realizing the separation operation of energization and connection. Through this design, the second pressing plate 55 slides downward first, so that the second L-shaped electricity-connecting plate 59, the second energizing rod 56 and the pins of the detection sensor 210 are connected first. Then the first pressing plate 54 slides upward, so that the first energizing rod 52 abuts against and connects with the energizing block in the arc-shaped block 31, ensuring the electrical connection of the detection instrument 24 circuit. Finally, through the connection of the first L-shaped electricity-connecting plate 58 and the second L-shaped electricity-connecting plate 59, the overall electrical connection of the circuit is realized. Through this design, the connection of the circuit is divided into multiple steps, ensuring a stable connection first and then conducting an energization test. This design can greatly avoid the risk of electric leakage caused by unstable connection during the energization process, further improving the safety (based on the common knowledge in this field, on the basis of ensuring the electrical connection of the circuit, insulating materials should be provided outside all other objects connected to electricity to avoid the shell being electrified and ensure the safety of the equipment).

[0046] Furthermore, the shape of the abutting triangular block 63 can be adjusted on the basis of ensuring the above functions.

[0047] Embodiment 3. This embodiment is an explanatory description based on Embodiment 2. Specifically, please refer to Figures 1 to 10The reinforcement component 7 includes a limiting block 72 for limiting the rotation of the extrusion shaft 44 . The limiting block 72 is driven by a pneumatic push rod 71 , and the pneumatic push rod 71 is controlled by the detection instrument 24 and the pneumatic component 8 .

[0048] The pneumatic assembly 8 includes a pneumatic groove 81 opened in the telescopic inner rod 26, one end of the pneumatic groove 81 is connected to the pneumatic push rod 71, and the other end of the pneumatic groove 81 is connected to the air groove 85 through the No. 1 hose 82, the No. 2 hose 83 and the inner groove 84 of the plate. The air groove 85 is opened in the No. 1 pressure plate 54, and a pressure block 86 is slidably connected in the air groove 85. The pressure block 86 is installed in the connecting groove 53, and the inner groove 84 of the plate is opened in the No. 2 pressure plate 55.

[0049] The design of the reinforcement component 7 and the pneumatic component 8 further ensures the stability of the connection between the detection sensor 210 and the detection port 27. When the first pressure plate 54 slides upward, due to the design of the air groove 85 and the pressure block 86, the gas in the air groove 85 will be squeezed and released through the pneumatic groove 81 and the first hose 82. The No. 2 hose 83, the groove 84 in the plate and the connecting conveyor are transported to the pneumatic push rod 71, thereby driving the limiting block 72 to slide downward, limiting the rotation of the extrusion shaft 44. At this time, due to the design of the different slopes of the interfering triangular block 63, the detection sensor 210 and the detection port 27 have been stably connected under the action of the fixing component 4. At this time, if the detection sensor 210 and the detection port 27 are stably connected, there will be misaligned teeth between the limiting block 72 and the extrusion shaft 44, and the limiting block 72 cannot be inserted into the gap between the tooth block 48 on the side wall of the extrusion shaft 44. Therefore, the No. 1 pressure plate 54 will not slide completely upward to the top, thereby driving the power-on block in the arc block 31 and the No. 1 power-on rod 52 to be unable to connect and energize. Through this design, the connectivity of the circuit is further limited to avoid the risk of leakage due to unstable connection.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
