[0021] The following will specifically describe the preferred embodiments of the present invention in conjunction with the drawings. The drawings constitute a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0022] As Figures 1-3As shown in the figure, a current sensor detection system provided by the utility model includes a workbench 100, a plurality of fixed jigs 200, a position detection component 300 and a current detection component 400. The workbench 100 includes a base 110 and a rotating ring 120. An annular groove 111 is formed on the base 110, and the rotating ring 120 is rotatably connected to the annular groove 111. A plurality of fixed jigs 200 are arranged along the circumference of the rotating ring 120. Grooves 210 for placing a current sensor M are formed at the tops of the plurality of fixed jigs 200. The position detection component 300 includes a first moving member 310 and a guide post 320. The first moving member 310 is installed on the workbench 100, and the output end of the first moving member 310 is connected to the guide post 320 to drive the guide post 320 to contact the column M1 of the current sensor M to detect the placement position of the current sensor M. The current detection component 400 includes a second moving member 410, a copper bar 420, a third moving member 430 and a connector 440. The second moving member 410 and the third moving member 430 are both installed on the workbench 100. The output end of the second moving member 410 is connected to the copper bar 420 to drive the copper bar 420 to be inserted into the current sensor M. The output end of the third moving member 430 is connected to the connector 440 to drive the connector 440 to be connected to the pin of the current sensor M.

[0023] Specifically, the current sensor M to be detected can be placed on the fixed jig 200. As the rotating ring 120 rotates, the fixed jig 200 can move to a position directly opposite the position detection component 300. At this time, the output end of the first moving member 310 is connected to the guide post 320 to drive the guide post 320 to contact the column M1 of the current sensor M to detect the placement position of the current sensor M, avoiding the current sensor M being placed in the wrong direction and affecting subsequent detection. Then, the rotating ring 120 drives the fixed jig 200 to rotate to a position directly opposite the current detection component 400. At this time, the output end of the second moving member 410 is connected to the copper bar 420 to drive the copper bar 420 to be inserted into the current sensor M. The current sensor M detects a current signal. At the same time, the output end of the third moving member 430 is connected to the connector 440 to drive the connector 440 to be connected to the pin of the current sensor M to detect the working state of the current sensor M. As the rotating ring 120 rotates, continuous loading and unloading and detection operations can be realized, and the detection efficiency is high.

[0024] In this implementation scheme, the workbench 100 includes a base 110 and a rotating ring 120. An annular groove 111 is formed on the base 110, and the rotating ring 120 is rotatably connected to the annular groove 111.

[0025] Among them, both the part of the base 110 inside and outside the rotating ring 120 can be used to install the structures for system detection, and the installation space is large.

[0026] In this implementation, a plurality of fixed fixtures 200 are arranged circumferentially along the swivel ring 120, and grooves 210 for placing the current sensor M are provided at the tops of the plurality of fixed fixtures 200.

[0027] This embodiment further includes a contact switch installed on the guide post 320 away from the first moving member 310. The number of guide posts 320 is multiple, and the multiple guide posts 320 correspond one by one to the multiple upright posts M1 of the multiple current sensors M.

[0028] When the current sensor M is placed correctly, that is, when it is placed upright, the multiple guide posts 320 can move to a position where they abut against the multiple upright posts M1 of the current sensor M. At this time, the contact switch is triggered, indicating that the detection is qualified. If the current sensor M is placed upside down, when the multiple guide posts 320 move to the maximum stroke, the multiple guide posts 320 are arranged at intervals with the multiple upright posts M1. At this time, the contact switch is not triggered, which means that the current sensor M is placed reversely and the placement position of the current sensor M needs to be adjusted.

[0029] It can be understood that the above contact switch can be externally connected to a display lamp. When the contact switch is triggered, the display lamp lights up for easy observation.

[0030] The current detection component 400 in this implementation includes a second moving member 410, a copper bar 420, a third moving member 430, and a connector 440. The second moving member 410 and the third moving member 430 are both installed on the workbench 100. The output end of the second moving member 410 is connected to the copper bar 420 to drive the copper bar 420 to be inserted into the current sensor M. The output end of the third moving member 430 is connected to the connector 440 to drive the connector 440 to be connected to the pins of the current sensor M.

[0031] It can be understood that the detection principle of the current sensor M is as follows: insert the copper bar 420 into the through hole in the middle of the current sensor M. The current sensor M senses the current and generates a voltage signal, which passes out through the pins. The connector 440 is connected to an external device, and it can be known whether the voltage signal meets the standard.

[0032] In one embodiment, both the first moving member 310 and the third moving member 430 are oil cylinders arranged inside the swivel ring 120.

[0033] In one embodiment, the second moving member 410 includes a mounting base 411 arranged outside the swivel ring 120, a first linear motor 412, and a second linear motor 413. The first linear motor 412 is fixedly arranged on the mounting base 411. The output end of the first linear motor 412 is connected to the second linear motor 413 to drive the second linear motor 413 to move along the radial direction of the swivel ring 120. The output end of the second linear motor 413 is connected to the copper bar 420 to drive the copper bar 420 to move in the vertical direction.

[0034] Such asFigure 4 As shown, in this embodiment, it further includes a limit sleeve 450 installed on the output end of the third moving member 430, and the limit sleeve 450 is used for cooperating and connecting with the column M1 of the current sensor M.

[0035] To improve the detection efficiency, in one embodiment, the number of grooves 210 on the fixed fixture 200 is multiple, and the corresponding number of guide posts 320, copper bars 420, and connectors 440 is also multiple.

[0036] After detecting the sensitivity of the current sensor M, to control the response range of the current sensor M, this implementation scheme further includes a calibration component 500 installed on the workbench 100, and the calibration component 500 is used to calibrate the current sensor M. Among them, the calibration component 500 is a structure that those skilled in the art can think of. For example, a current sensor calibration device based on current proposed in the utility model patent with the application number CN201721858956.0.

[0037] This implementation scheme further includes a coding component 600 installed on the workbench 100. Among them, the coding component 600 is a structure that those skilled in the art can think of. For example, a laser coding device for integrated processing of current sensors proposed in the utility model patent with the application number CN202322891899.8.

[0038] This implementation scheme further includes a blanking component 700 installed on the workbench 100. Among them, the blanking component 700 can be implemented by structures such as a conveyor belt.

[0039] In this embodiment, the position detection component 300, current detection component 400, calibration component 500, coding component 600, and blanking component 700 are arranged in sequence along the rotation direction of the rotating ring 120. The number of fixed fixtures 200 is six, and when the rotating ring 120 rotates, five of the fixed fixtures 200 are respectively facing the position detection component 300, current detection component 400, calibration component 500, coding component 600, and blanking component 700.

[0040] Compared with the prior art: The current sensor M to be detected can be placed on the fixed fixture 200. As the rotary ring 120 rotates, the fixed fixture 200 can be moved to a position directly facing the position detection component 300. At this time, the output end of the first moving member 310 is connected to the guide post 320 to drive the guide post 320 to contact the upright post M1 of the current sensor M to detect the placement position of the current sensor M, avoiding the reverse placement of the current sensor M and affecting subsequent detection. Subsequently, the rotary ring 120 drives the fixed fixture 200 to rotate to a position directly facing the current detection component 400. At this time, the output end of the second moving member 410 is connected to the copper bar 420 to drive the copper bar 420 to be inserted into the current sensor M. The current sensor M detects a current signal. At the same time, the output end of the third moving member 430 is connected to the connector 440 to drive the connector 440 to be connected to the pin of the current sensor M to detect the working state of the current sensor M. As the rotary ring 120 rotates, continuous loading and unloading and detection operations can be realized, and the detection efficiency is high.

[0041] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
