Description

Technical Field

[0001] The invention relates to the field of electromagnetic radiation detection, in particular to a radiation interference test device for automobile electronic components. Background Art

[0002] With the popularization and development of family cars, on-board radars are increasingly used in cars. On-board radar is a sensor used to detect and sense the vehicle's surrounding environment. It measures the distance, speed and direction between objects and the car by emitting and receiving electromagnetic waves, thereby providing the driver with comprehensive vehicle surrounding information to ensure driving safety. Since the radar emits electromagnetic wave pulses to generate electromagnetic radiation, and the power distribution system formed by the radar combined with the power supply circuit also generates more electromagnetic radiation when working, these electromagnetic radiations will interfere with the normal operation of other electronic equipment in the car, causing data transmission errors, equipment failures and other problems, and on the other hand, they will endanger human health. Therefore, EMC testing (also called electromagnetic compatibility testing) is required before the on-board radar leaves the factory, so a radar electromagnetic radiation test device will be used.

[0003] The existing radar electromagnetic radiation test equipment has many technical drawbacks when in use. First, the current radar components are subjected to electromagnetic detection in an open workshop without shielding facilities. On the one hand, there is interference from the external electromagnetic field, and on the other hand, it causes excessive dispersion of its own electromagnetic radiation, both of which will lead to a reduction in the accuracy of the detection results; second, the current electromagnetic radiation detector adopts a fixed structure. On the one hand, it is time-consuming and labor-intensive to detect in turn, which reduces the detection efficiency; on the other hand, the detection distance cannot be adjusted, the detection range is small, and the flexibility is low, resulting in a single detection data; third, when the groove wheel structure is used to drive the intermittent movement of the test bench, due to the inertia of the circular motion of the test bench, the positioning of the radar components on the test bench will be inaccurate, affecting the subsequent detection process.

[0004] To sum up, considering that the existing facilities cannot meet the work requirements, we propose a radiation interference test device for automotive electronic components. Summary of the invention

[0025] As a preferred embodiment of the automotive electronic component radiation interference test device of the present invention, the following is provided: The hinge piece includes a hinge shaft and two groups of leaf pieces.

[0026] The present invention hereby provides an automotive electronic component radiation interference test device through improvement. Compared with the prior art, it has the following significant improvements and advantages:

[0027] (1) Start the uniform-speed motor to drive one set of material-turning rollers to rotate. Through the meshing of two sets of direction-changing gears, the other set of material-turning rollers will rotate in the opposite direction. The radar components falling from the feeding inclined pipe first enter the rubber pad area. The radar components with the insertion part facing down can be directly inserted between the two rubber pads. With the movement of the material-turning rollers, the radar components are pushed towards the inclined direction. The radar components with the detection part facing down will come into contact with the moving rubber pads during the falling process, causing the radar components to turn over until the insertion part is inserted between the two rubber pads, achieving the purpose of automatically correcting the position. The automation degree is high. The radar components transition from the rubber pads to the thin shaft part, and the widened blanking gap allows the radar components to lose restraint and fall vertically downward, achieving the purpose of automatic material guiding.

[0028] (2) The cylinder rod drives the material-pushing tooling to return to its position. During the return process of the pressure-sealed door, the pressing plate moves downward together with the pressure-sealed door and enters the arc-shaped groove to squeeze the corrugated airbag. On the one hand, it has a buffering effect to avoid the impact damage of the door body. On the other hand, the corrugated airbag is compressed, and the sulfur hexafluoride gas inside the corrugated airbag floods into the shielding airbag through the positioning pipe, causing the originally deflated shielding airbag to inflate and expand, fully fitting around the pressure-sealed door, achieving the effects of electromagnetic shielding and sealing with the help of the internal gas.

[0029] (3) While the crank drive post moves in the strip-shaped wheel groove, the pressing part contacts the pressing post on the lock. At this time, the locking wheel on the lock rolls along the wheel surface of the grooved wheel disc. When the crank drive post leaves the strip-shaped wheel groove, the pressing post on the lock just moves to the convex surface of the pressing part, thus generating an outward pressing force on the first connecting rod, causing the central rotating seat to rotate slightly. The second connecting rod on the other side moves inward. By using the partial insertion of the locking wheel into the notch of the strip-shaped wheel groove, the grooved wheel disc is locked to prevent the inspection table from continuously moving due to inertia, improving the positioning accuracy of the electromagnetic shielding box and facilitating the subsequent smooth progress of feeding and detection.

[0030] (4) Start the second servo motor to cause the rotating curved surface table to rotate around the circumferential limit inner groove, making the rolling balls move along the curved surface rolling path. The tension spring drives the adjusting post to move downward through the reset tension, and then respectively uses several groups of second connecting rods to pull the protective shell seat downward, so that each group of lengthened detection heads extends downward through the adjustment opening and enters the inner detection chamber. It cooperates with the electromagnetic shielding performance of the electromagnetic shielding box to detect the electromagnetic radiation value generated when the radar components work, and measures multiple groups of data by changing the distance to the radiation source during the slow downward movement of the lengthened detection heads. The detection range is expanded, the credibility of the detection data is improved, and multiple groups of radars can be detected at one time, improving the work efficiency.

[0031] (5) With the driving force during detection, the adjustment column moves downward, driving each group of protective cases to move downward to the lowest point. The two trigger rods insert upward into the jacks and respectively contact the contact surfaces of the disassembly handles, causing the swing rods to rotate around the two third bearing seats. The hooks originally at the bottom of the electromagnetic radiation detector follow the swing and respectively disengage from the bottom of the electromagnetic radiation detector. The electromagnetic radiation detector drops onto the upper end face of the electromagnetic shielding box. At this time, each group of protective case seats moves upward for reset, thus achieving the complete separation of the protective case seats and the electromagnetic shielding box, achieving the purpose of automatic unified disassembly, saving time and effort, and having a high degree of automation.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment 1

[0051] As Figures 1-13 shown, this embodiment provides a radiation interference test device for automotive electronic components, including a base 1. An upwardly opening limit rotating groove 2 is provided inside the base 1, and an intermittent inspection table 3 is rotatably arranged in the limit rotating groove 2. A sliding support plate 7 for supporting the intermittent inspection table 3 is riveted to the bottom of the limit rotating groove 2. The upper end surface of the sliding support plate 7 is smooth, playing a role of sliding support and improving the stability of the movement of the intermittent inspection table 3.

[0052] Furthermore, an external fixing seat 60 is welded to the outer side surface of the base 1. A pusher cylinder seat 61 is arranged at the upper end of the external fixing seat 60. One end of the pusher cylinder seat 61 is in non-contact docking with the upper end surface of the intermittent inspection table 3 through a docking platform 68, as Figure 1 、 Figure 2 and Figure 10 shown.

[0053] Among them, a pusher cylinder 62 is horizontally installed inside the pusher cylinder seat 61. A cylinder rod 63 extends horizontally outwardly inside the pusher cylinder 62 and is movably arranged. The end of the cylinder rod 63 is welded with a pusher tooling 64. A double-layer fitting surface 65 acting on the radar component 90 is arranged outside the pusher tooling 64, which is in fit with the outer side surface of the radar component 90. Lifting arc blocks 66 acting on the pressure-type sealing door 54 are symmetrically installed on the upper end surface of the pusher tooling 64. The lifting arc blocks 66 have an arc surface with a curved surface rising and are in sliding contact with the pressure-type sealing door 54, as Figure 10 and Figure 11 shown.

[0054] Among them, the pusher tooling 64 pushes the radar component 90 to horizontally enter the upper end surface of the intermittent inspection table 3 from the guiding channel 67, and the two surfaces are in a horizontally aligned state.

[0055] Furthermore, a chain plate feeder 70 is cross-connected in the middle of the docking platform 68.

[0058] In this embodiment, two groups of inclined material turning rollers 751 are symmetrically arranged inside the material turning box 75.

Both ends of the material turning roller 751 are fixed to the inner wall of the material turning box 75 through a second bearing seat 752. A rubber pad 753 is wrapped around the right position of each group of material turning rollers 751. The rubber pad 753 can protect the radar component 90 from being worn.

An internal inspection chamber 51 for placing the radar component 90 is provided inside the electromagnetic shielding box 50. The radar component 90 includes a signal generator, a sensor, a controller, and a power distribution system.

[0065] Among them, an arc-shaped groove 95 is opened at the bottom of the internal inspection chamber 51. A corrugated airbag 96 acting on the pressing plate 58 is movably arranged in the arc-shaped groove 95. The corrugated airbag 96 is multi-segment corrugated and has the characteristic of deformation and restoration. Sulfur hexafluoride gas is stored in the corrugated airbag 96, which has strong electromagnetic shielding properties. Airbag storage grooves 97 are opened on the four side walls of the material port 53. Shielding airbags 98 are communicated in the four sets of airbag storage grooves 97. Part of the shielding airbag 98 is adhesively bonded to the groove wall of the airbag storage groove 97. Normally, the shielding airbag 98 is completely in the airbag storage groove 97. The corrugated airbag 96 is communicated with the bottom of the shielding airbag 98 through a positioning tube, as Figure 8 shown.

[0066] Further, a circular opening 4 is formed through the middle of the intermittent inspection table 3, and the support column 5 passes through the circular opening 4. A widened chassis 6 is fixedly arranged at the lower end of the support column 5. A positioning bearing sleeve 10 sleeved outside the support column 5 is riveted to the lower end of the intermittent inspection table 3, as Figure 1 , Figure 2 and Figure 3 shown.

[0067] Among them, a sheave disc 11 is sleeved outside the sliding support plate 7 through the positioning bearing sleeve 10. A plurality of groups of strip-shaped wheel grooves 12 are evenly formed on the wheel surface of the sheave disc 11, as Figure 3 and Figure 4 shown.

[0068] Among them, a first servo motor 13 is vertically installed downward inside the sliding support plate 7. The lower end of the first servo motor 13 is connected to a first rotating shaft 14. An extrusion member 15 is welded to the lower end of the first rotating shaft 14. An arc-shaped adjusting portion 16 (the arc-shaped adjusting portion 16 includes a convex surface and a concave surface) is arranged around the outer side surface of the extrusion member 15, as Figure 3 and Figure 4 shown.

[0069] Further, a crank 17 is sleeved below the extrusion member 15 at the lower end of the first rotating shaft 14. A crank driving column 18 acting on the strip-shaped wheel groove 12 is welded to the end of the crank 17. A locking device 19 is arranged outside the extrusion member 15, as Figure 4 shown.

[0070] Specifically, the locking device 19 includes a central rotating seat 190, a positioning shaft 191, a first bearing seat 192, a first connecting rod 193, a pressing column 194, a second connecting rod 195, a wheel seat 196, a locking wheel 197, a spring column 198 and a return spring 199, as Figure 5 shown.

[0071] In this embodiment, a positioning shaft 191 is welded to the upper end of the central rotating seat 190. The upper end of the positioning shaft 191 is connected to the lower end surface of the sliding support plate 7 through the first bearing seat 192. The central rotating seat 190 rotates around the first bearing seat 192. One side of the central rotating seat 190 is connected to a first connecting rod 193, and a pressing column 194 acting on the arc-shaped adjusting portion 16 is installed at the end of the first connecting rod 193.

[0072] In this embodiment, a second connecting rod 195 is connected to the other side of the central rotating seat 190. A wheel seat 196 is fixed to the end of the second connecting rod 195. A locking wheel 197 is rotatably arranged downward inside the wheel seat 196. The locking wheel 197 acts on the notch position of the strip-shaped wheel groove 12. The locking wheel 197 is slightly larger than the diameter of the notch. A spring column 198 is fixedly arranged in the middle of the second connecting rod 195. The spring column 198 and the inner wall of the base 1 are horizontally connected by a return spring 199. The return spring 199 pulls the second connecting rod 195 to move outward to ensure that the pressing column 194 and the concave surface of the arc adjusting portion 16 are in close contact.

[0073] Further, the upper end of the support column 5 is welded with a top seat 20. The outer side surface of the top seat 20 is fixed to the upper end surface of the base 1 through an L-shaped side arm 21, which plays a role in connecting and fixing. A plurality of groups of lifting grooves 23 are evenly opened along the edge of the upper end surface of the top seat 20. A protective shell seat 24 is limitedly arranged in each group of lifting grooves 23, and the two are in sliding contact, as Figure 1 、 Figure 2 and Figure 6 shown.

[0074] Among them, an electromagnetic radiation detector 25 is installed inside the protective shell seat 24. The lower end of the electromagnetic radiation detector 25 extends downward to be provided with an extended detection head 26. The upper end of each protective shell seat 24 is fixedly connected to the adjusting column 30 through a connecting rod 27, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown.

[0075] Further, a guiding sliding groove 31 for the movement of the adjusting column 30 is upwardly opened inside the support column 5 and the top seat 20. A sliding block 32 that acts on the guiding sliding groove 31 is arranged on the outer side surface of the adjusting column 30, which plays a role in limiting and guiding, and improves the stability of the movement of the adjusting column 30, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown.

[0076] Specifically, a lifting column 33 is welded to the lower end of the adjusting column 30. A limiting circular plate 34 is arranged inside the support column 5. A column hole 35 for the lifting column 33 to pass through is penetrated through the middle position inside the limiting circular plate 34. The column hole 35 plays a role in limiting and guiding. A tension spring 36 sleeved on the outer side of the lifting column 33 is fixed between the adjusting column 30 and the limiting circular plate 34. The tension spring 36 is in a stretched state. A spring made of a high-elasticity and durable material is selected. A rolling ball 37 is arranged at the lower end of the lifting column 33, as Figure 6 and Figure 7 shown.

[0077] Among them, a second servo motor 40 is vertically installed downward inside the limit circular plate 34. The lower end of the second servo motor 40 is connected to a second rotating shaft 41. The lower end of the second rotating shaft 41 is welded with a rotating curved surface table 42. A circumferential limit inner groove for the circumferential movement of the rotating curved surface table 42 is provided inside the support column 5. A curved surface raceway 43 acting on the rolling ball 37 is arranged on the upper end surface of the rotating curved surface table 42, which has a certain curved surface slope, such as Figure 6 and Figure 7 shown.

[0078] Furthermore, the adjusting column 30, the lifting column 33, the connecting rod 27 and the protective housing base 24 are all made of lightweight materials.

[0079] Furthermore, a control console 92 is connected to the outside of the base 1, and a display 93 is placed on the control console 92, such as Figure 2 shown.

[0080] Furthermore, the electromagnetic radiation detector 25 transmits data to the control console 92 through a data cable 91, and the numerical value is displayed on the display 93. This is prior art and will not be elaborated here.

[0081] When this embodiment is in use, first start the vibration motor 94 at the bottom of the vibrating discharging hopper 77, so that the radar components 90 in the vibrating discharging hopper 77 are discharged in sequence through vibration, slide into the tipping box 75 from the discharging inclined pipe 76. By starting the uniform speed motor 756 on the tipping box 75, one set of tipping rollers 751 is driven to rotate, and through the meshing action of two sets of reversing gears 757, the other set of tipping rollers 751 rotates in the opposite direction. The two sets of tipping rollers 751 achieve synchronous opposite movements. The radar components 90 sliding down from the discharging inclined pipe 76 first enter the rubber pad 753 area. The radar components 90 with the plugging part facing downward can be directly inserted between the two rubber pads 753. Along with the movement of the tipping rollers 751, the radar components 90 are toggled to transfer in the inclined direction. The radar components 90 with the detection part facing downward will contact the moving rubber pads 753 during the falling process because the width of the detection part is greater than the distance between the two rubber pads 753, which causes the radar components 90 to turn over until the plugging part is inserted between the two rubber pads 753 and is transferred along with the movement of the tipping rollers 751.

[0082] Afterwards, the radar component 90 transitions from the rubber pad 753 to the thin shaft portion 754, and the radar component 90 is freed from restraint and falls vertically downward by utilizing the widened blanking gap 755, enters the vertical material tube 72, and is directly stopped on the chain plate 71 at the bottom of the vertical material tube 72 after being guided. The chain plate feeder 70 continues to work, allowing the chain plate 71 to drive the radar component 90 to pass through the opening 73 and be transported toward the docking station 68. The radar component 90 is blocked by the inner wall of the docking station 68 and stops on the guide. Towards the channel 67 (several groups of radar components 90 are arranged in sequence toward the vertical material tube 72 with the guide channel 67 as the starting point, waiting for pushing), and then the pushing cylinder 62 is started, the cylinder rod 63 is extended, and the double-layer bonding surface 65 on the pushing tooling 64 is used to fully wrap the outer side surface of the radar component 90, and push the radar component 90 along the guide channel 67 toward the intermittent inspection table 3, until the radar component 90 smoothly transitions from the guide channel 67 to the upper end surface of the intermittent inspection table 3.

[0083] Then, the pusher tooling 64 uses the radar component 90 to contact the pressure-type sealing door 54 of the electromagnetic shielding box 50 opposite, and the two generate an extrusion force, causing the pressure-type sealing door 54 to flip open around the two sets of leaf pieces 56 (the two sets of steel wire heads are squeezed toward each other, causing the torsion spring 57 to deform and bend during the movement of the leaf pieces). Then, the two sets of lifting arc blocks 66 on the pusher tooling 64 take over from the radar component 90 to lift the pressure-type sealing door 54, allowing it to continue to flip until the radar component 90 passes through the material port 53 and enters the inner detection chamber 51. At this time, the cylinder rod 63 drives the pusher tooling 64 to return to its original position, and the pressure-type sealing door 54, under the condition of losing its restraint, uses the torsion spring to open. The resetting force of 57 drives the pressure-type sealing door 54 to close and continue to seal, that is, the loading work of a group of radar components 90 is successfully completed. In the process of the pressure-type sealing door 54 returning to its original position, the pressure plate 58 moves downward with the pressure-type sealing door 54 and enters the arc groove 95 to squeeze the corrugated airbag 96, which has a buffering effect and compresses the corrugated airbag 96. The sulfur hexafluoride gas inside the corrugated airbag 96 flows into the shielding airbag 98 through the positioning tube, allowing the originally deflated shielding airbag 98 to expand after inflating, and partially extend out of the airbag storage groove 97, fully fitting around the pressure-type sealing door 54, and using the internal gas to achieve the effect of electromagnetic shielding sealing.

[0084] Then, the first servo motor 13 is started to drive the first rotating shaft 14 to rotate, causing the crank 17 to make a circular motion. During the movement of the crank 17, the crank driving column 18 enters into one group of strip wheel grooves 12 and moves in the strip wheel grooves 12. The two generate relative forces, causing the groove wheel plate 11 to rotate a certain angle, thereby making the intermittent inspection table 3 rotate intermittently, allowing an adjacent group of electromagnetic shielding boxes 50 to be transported to the position aligned with the guide channel 67, and then pushing the material to achieve the purpose of loading materials in turn, and the operation is repeated in this way.

[0085] While the crank drive post 18 moves within the strip wheel groove 12, the extrusion member 15 moves synchronously with the first rotating shaft 14. The concave surface of the extrusion member 15 contacts the pressing post 194 on the lock 19. At this time, the locking wheel 197 on the lock 19 rolls along the wheel surface of the grooved wheel disc 11 (at this time, the return spring 199 exerts a pulling force on the second connecting rod 195 to ensure the tension between the locking wheel 197 and the grooved wheel disc 11). When the crank drive post 18 leaves the strip wheel groove 12, the pressing post 194 on the lock 19 just moves onto the convex surface of the extrusion member 15, thereby generating an outward extrusion force on the first connecting rod 193, causing the central rotating seat 190 to slightly rotate. The second connecting rod 195 on the other side moves inward, and the local part of the locking wheel 197 extends into the notch position of the strip wheel groove 12 and gets stuck, locking the entire grooved wheel disc 11 to prevent it from continuously moving due to inertia and accurately positioning the electromagnetic shielding box 50.

[0086] After the loading and power-on operations of all the electromagnetic shielding boxes 50 on the intermittent inspection table 3 are completed, the second servo motor 40 is started, and the second rotating shaft 41 rotates, causing the rotating curved surface table 42 to rotate around the circumferential limit inner groove, making the rolling ball 37 move along the path of the curved surface raceway 43. As the slope of the curved surface raceway 43 decreases, the tension spring 36 drives the adjusting post 30 to move downward through the return tension (the lifting post 33 descends along the post hole 35), thereby respectively using several groups of second connecting rods 195 to pull the protective housing seat 24 downward, so that the extended detection heads 26 of each group of electromagnetic radiation detectors 25 move downward through the adjusting port 52 and extend into the inner detection chamber 51, cooperate with the electromagnetic radiation value generated when the radar component 90 in the electromagnetic shielding box 50 works, and measure multiple sets of data by changing the distance to the radiation source during the slow downward movement of the extended detection heads 26. The data is transmitted to the receiver of the console 92, and the radiation values are comprehensively analyzed to determine whether the radar component 90 is qualified, and multiple sets of radar components 90 can be detected at one time.

[0087] Embodiment 2

[0088] Based on Embodiment 1, the electromagnetic radiation detector 25 needs to be calibrated and maintained regularly during use to ensure the measurement accuracy. Therefore, it needs to be frequently disassembled and taken out from the protective housing seat 24, usually manually. Due to the large quantity, this is time-consuming and laborious, and the work efficiency is low. To solve the above technical problems, we have the following design, as Figures 14-16 shown.

[0089] Specifically, swing rods 81 are symmetrically arranged on both sides inside the protective housing seat 24. The upper ends of the swing rods 81 are symmetrically welded with short shafts 82. Each group of short shafts 82 is connected to the inner wall of the protective housing seat 24 through a third bearing seat 83, as Figure 16as shown

[0090] Among them, a lower end portion of the swing rod 81 is connected with a lower end surface hook 84 acting on the electromagnetic radiation detector 25. A disassembly handle 85 is arranged on a side surface of the swing rod 81. An upper end of the disassembly handle 85 is fixed to an inner wall of the protective housing base 24 through a compression spring 86. The compression spring 86 applies a force to the disassembly handle 85 in a natural state to ensure that the hook 84 can fix the electromagnetic radiation detector 25, as Figure 15 and Figure 16 shown

[0091] Among them, a contact surface 87 is arranged at a lower end of the disassembly handle 85. Jacks 88 communicating with the disassembly handle 85 are symmetrically formed at a bottom of the protective housing base 24. A trigger rod 80 extending into the jacks 88 is welded to an upper end surface of the electromagnetic shielding box 50, as Figures 14-16 shown

[0092] When in use in this embodiment, when the electromagnetic radiation detector 25 needs to be disassembled uniformly, the adjusting column 30 is driven to move downward through a series of transmissions, driving each group of protective housing bases 24 to move downward to the lowest point. In this process, two groups of trigger rods 80 on the upper end surface of the electromagnetic shielding box 50 are inserted upward into the jacks 88 and respectively contact the contact surface 87 of the disassembly handle 85, applying pressure to the disassembly handle 85 (causing the disassembly handle 85 to move slightly upward, and the compression spring 86 is compressed to generate a reset elastic force), causing the swing rod 81 to rotate around two groups of third bearing seats 83, making the hooks 84 originally at the bottom of the electromagnetic radiation detector 25 swing accordingly and respectively disengage from the bottom of the electromagnetic radiation detector 25, enabling the electromagnetic radiation detector 25 to lose restraint and then slide downward by gravity onto the upper end surface of the electromagnetic shielding box 50. At this time, each group of protective housing bases 24 is then moved upward for a reset movement, thereby realizing the complete separation of the protective housing base 24 and the electromagnetic shielding box 50, achieving the purpose of automatic unified disassembly.
