Description

[0001] The invention relates to the field of lightning indirect effect experimental detection, and more specifically, to a lightning indirect effect pin injection test pin positioning visualization system. Background Art

[0002] The purpose of the lightning indirect effect pin injection test is to evaluate the device interface circuit's ability to resist damage, transient interference, and component damage under lightning induced transient signals, as well as the voltage and current data of various line components. This helps ensure that the device can work normally in a lightning environment and reduce system failures or damage caused by lightning interference.

[0003] The simulated lightning induction signal is injected into the interface circuit of the device under test through the pins. The pins are the medium for signal transmission. Their design and layout must meet the test requirements to ensure that the signal can be accurately and effectively transmitted to the circuit under test.

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figure 1 - Fig. 9 As shown, a pin positioning visualization system for a lightning indirect effect pin injection test comprises: a probe 11, a pin socket 14 matching the pin is provided on one side of the probe 11 close to the pin, a connecting line 12 is fixedly connected to the end of the probe 11 away from the pin, a concave groove 15 is provided at the center of the two pin sockets 14, a visual mechanism 2 is provided in the concave groove 15, and a real-time picture of the probe 11 and the pin is inserted and removed, so that the test pin can be inserted and removed accurately;

[0033] The purpose of the lightning indirect effect pin injection test is to evaluate the device interface circuit's ability to resist damage, transient interference and component damage under the action of lightning induced transient signals. Before conducting the lightning indirect effect pin injection test, the device under test must be fully inspected and prepared. After confirming the integrity of the device interface, align the probe 11 with the pin and connect the probe 11 to the pin.

[0034] The visual mechanism 2 includes a camera 21, a data guide 23 is provided at a connection end of the camera 21, and a display screen 24 is connected to the other end of the data guide 23 for displaying the positions of the pins and the pin sockets 14;

[0035] When the probe 11 is aligned with the pin, the camera 21 is integrated in the center of the camera 21 and can capture the image around the camera 21 in real time. When the probe 11 is close to the probe, the camera 21 will transmit the image to the display screen 24. Through real-time visual feedback and image recognition technology, the accuracy of the probe 11 inserted into the probe can be greatly improved, and inaccurate insertion caused by human judgment or mechanical errors can be reduced, so as to help the experimenter to quickly, accurately and effectively plug and unplug the test pins and avoid unnecessary failures, thereby ensuring the smooth progress of the test, shortening the number and cycle of tests, and improving the turnover rate of test projects.

[0036] An auxiliary viewing mechanism 3 is provided on the side of the camera 21 close to the mirror surface. The auxiliary viewing mechanism 3 includes two arc plate frames 31. Two liquid passing tubes 34 are provided between the two arc plate frames 31. A positioning point 33 is provided at the center of the liquid passing tube 34. Through real-time observation and adjustment by the camera 21, combined with the intuitive way of aligning the positioning point 33 with the insertion needle, the accuracy of the insertion needle can be greatly improved. The two symmetrical positioning points 33 assist the probe 11 to move forward in a straight line.

[0037] When using the camera 21, the two arc plate frames 31 are opened like opening eyes, and two liquid tubes 34 are pulled out after opening. There is a cross frame positioning point 33 at the center of the two liquid tubes 34. From the video, the two cross frame positioning points 33 are aligned with the two probes. As long as the cross frame positioning points 33 move along the two probes, the probes can be accurately inserted. The positioning points 33 in the design serve as visual reference points, which can clearly indicate the deviation of the probes from the expected position, so that the operator or the automation system can make timely adjustments, thereby effectively reducing inaccurate insertions caused by human judgment or mechanical errors. Due to the improvement in accuracy and the reduction in errors, the entire insertion process can be completed faster, which improves work efficiency and reduces time waste due to repeated operations due to inaccurate insertion.

[0038] A plurality of lighting lamps 22 are arranged on the outer ring of the side of the camera 21 close to the insertion pin, which are used to provide sufficient light illumination when the probe 11 approaches the insertion pin. The side of the camera 21 close to the probe is lower than the side of the probe 11, which is used to protect the camera 21;

[0039] When the camera 21 is working, the lighting of the plurality of lighting lamps 22 can provide sufficient light for the camera 21 .

[0040] The auxiliary viewing mechanism 3 also includes a rotating plate 36 located at both ends of the arc plate frame 31 and fixedly connected thereto, a limiting groove 37 is provided on the outer wall of the rotating plate 36, a pull wire 38 is fixedly arranged inside the limiting groove 37, and the two rotating plates 36 of the two arc plate frames 31 are tangent to the rotating plate 36 at the same end, and a plurality of reset elastic bands 39 are fixedly arranged between the two tangent rotating plates 36 at the same end, and the two arc plate frames 31 are rotatably connected to the camera 21 through the rotating plates 36;

[0041] After the staff member pinches the two acupressure airbags 48, he can pull the pull wire 38, and by pulling the pull wire 38 on the rotating plate 36, he can pull the rotating plate 36 to rotate, so that the two closed arc plate frames 31 can be opened to allow the camera 21 to leak out, thereby preventing the camera 21 from being blocked.

[0042] A protective cover 32 is fixedly provided on one side of the two arc plate frames 31 away from the symmetry axis of the two arc plate frames 31. The two protective covers 32 are fixedly connected to the inner wall of the camera 21 on one side away from the arc plate frames 31. The two protective covers 32 are elastic and can be stretched and deformed. The closing of the two protective covers 32 fully surrounds the mirror surface of the camera 21.

[0043] The protective cover 32 can be opened when the two arc plate frames 31 are opened. When the camera 21 is not in use, the protective cover 32 can be pulled out by closing the two arc plate frames 31 to completely cover the camera 21, so that the camera 21 is protected by the protective cover 32.

[0044] The inner wall of the protective cover 32 is provided with an inner wall membrane 304 of the same size as itself, and the upper and lower ends of the inner wall membrane 304 are fixedly connected to the arc plate frame 31 and the inner wall of the camera 21 respectively, and a plurality of supporting air columns 305 are fixedly provided between the protective cover 32 and the inner wall membrane 304, and the supporting air columns 305 are hollow and have a greater hardness than the protective cover 32 and the inner wall membrane 304, and a plurality of blowing holes 306 are opened on the inner wall membrane 304;

[0045] When the two protective covers 32 are opened, the protective covers 32 and the inner wall membrane 304 can be stretched open by a plurality of supporting air columns 305, so that the space between the protective covers 32 and the inner wall membrane 304 is filled with air; thereafter, when the two protective covers 32 shrink and are squeezed by the arc plate frame 31, the air between the protective covers 32 and the inner wall membrane 304 can be ejected from a plurality of blowing holes 306 and blown onto the surface of the camera 21, thereby blowing off the dust on the mirror surface of the camera 21.

[0046] A liquid storage chamber 301 is provided inside the arc plate frame 31 , and an expansion bag 303 is provided inside the liquid storage chamber 301 . The expansion bag 303 is communicated with the gap between the protective cover 32 and the inner wall membrane 304 through a pipeline.

[0047] Colored liquid 302 is injected between the expansion bag 303 and the liquid storage chamber 301, the liquid storage chamber 301 is connected with two liquid pipes 34, and the liquid pipes 34 are connected with the positioning point 33, and the positioning point 33 is a cross frame structure;

[0048] When the arc plate frame 31 with the two protective covers 32 is opened, part of the air between the protective covers 32 and the inner wall membrane 304 will be squeezed into the expansion bag 303, so that the expansion bag 303 expands in the liquid storage chamber 301. The color liquid 302 in the liquid storage chamber 301 can be squeezed into the liquid passage 34 and the positioning point 33 by the increase in the volume of the expansion bag 303, so that the positioning point 33 changes color, which is conducive to the staff to clearly see the position of the positioning point 33;

[0049] As time goes by, the color liquid 302 in the liquid passage tube 34 and the positioning point 33 will slowly flow back, and the liquid passage tube 34 and the positioning point 33 will return to a transparent state.

[0050] A control mechanism 4 is provided in the probe 11, and the control mechanism 4 includes a reciprocating cylinder 41 fixedly connected to the probe 11, a ventilation pipe 45 is provided at the air inlet end of the reciprocating cylinder 41, and a finger pressure air bag 48 is provided at the end of the ventilation pipe 45 away from the reciprocating cylinder 41, and the finger pressure air bag 48 is fixed at the hand-pinching position of the probe 11.

[0051] A piston 42 is slidably disposed inside the probe 11 , and a guide column 43 fixedly connected to the reciprocating cylinder 41 passes through the center of the piston 42 .

[0052] A main pull belt 44 is fixedly provided on one side of the piston 42, and an end of the main pull belt 44 away from the piston 42 passes through the guide column 43 and is provided with a support column 46. The support column 46 and one side of the support column 46 close to the rotating plate 36 are fixedly provided with two wire tubes 47, and the pull wire 38 is fixedly connected to the main pull belt 44;

[0053] After the staff member pinches the finger pressure airbag 48, the gas in the finger pressure airbag 48 flows into the reciprocating cylinder 41 through the ventilation tube 45. As the air pressure in the reciprocating cylinder 41 increases, the piston 42 is pushed to slide, and the sliding of the piston 42 pulls the main pull belt 44, and the main pull belt 44 pulls the pull line 38. Finally, the piston 42 is pulled back to its original position through the elastic band on the piston 42.

[0054] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
