Description

Technical Field

[0001] This application relates to the field of millimeter-wave device testing technology, and in particular to a millimeter-wave airtightness leak detection device. Background Technology

[0002] Millimeter-wave radar uses millimeter waves, typically referring to the 30–300 GHz frequency range. Since the wavelength of millimeter waves falls between centimeter waves and light waves, they combine the advantages of microwave and photoelectric guidance. Compared to centimeter-wave seekers, millimeter-wave seekers are smaller, lighter, and have higher spatial resolution. Compared to infrared, laser, and television optical seekers, millimeter-wave seekers have stronger penetration capabilities through fog, smoke, and dust, offering all-weather, all-time performance. Furthermore, millimeter-wave seekers have superior anti-jamming and anti-stealth capabilities compared to other microwave seekers.

[0003] Regarding the aforementioned technologies, airtightness testing devices are required in the manufacturing process of millimeter-wave radar. However, existing airtightness testing devices generally require manual testing of each millimeter-wave radar unit during use, resulting in low testing efficiency. Summary of the Invention

[0004] In order to enable automatic batch airtightness testing of millimeter-wave radars after production, this application provides a millimeter-wave airtightness leak detection device.

[0005] The millimeter-wave airtightness leak detection device provided in this application adopts the following technical solution:

[0006] A millimeter-wave airtightness leak detection device includes a spray tank, a first conveyor, and a second conveyor. Both the first and second conveyors are connected to the top of the spray tank. The top of the spray tank is equipped with a gripping component for grabbing the millimeter-wave radar transmitted from the first conveyor. The spray tank is equipped with a transmission component for transmitting the millimeter-wave radar into its interior. The spray tank is connected to a detection component for detecting the airtightness of the millimeter-wave radar.

[0007] By adopting the above technical solution, the first conveyor transports the millimeter-wave radar close to the spray tank. The gripping component of the spray tank grips the millimeter-wave radar and transfers it to the conveying component. The conveying component then transfers the millimeter-wave radar into the spray tank, where it undergoes a water spray test. After the conveying component transfers the millimeter-wave radar out of the spray tank, the detection component checks for any water leakage. Once the test is completed, the gripping component transfers the millimeter-wave radar to the second conveyor for the next step, thus enabling automatic batch airtightness testing of the produced millimeter-wave radar.

[0008] Optionally, the conveying assembly includes a placement plate, two first connecting rods, and two second connecting rods. The two first connecting rods and the two second connecting rods are all hinged inside the spray tank. The two first connecting rods and the two second connecting rods are all hinged to the placement plate. The second connecting rods are located above the first connecting rods. The first connecting rods and the second connecting rods are parallel to each other. The two second connecting rods are parallel to each other. The spray tank is equipped with a first motor for driving the first connecting rods to rotate. The placement plate is equipped with a self-locking component for limiting its own rotation.

[0009] By adopting the above technical solution, when the millimeter-wave radar is placed on the placement plate, the self-locking component is released, the first motor drives the first connecting rod to rotate, and the first connecting rod cooperates with the second connecting rod to keep the placement plate in a horizontal state and flip it into the spray water tank for spraying. After the spraying is completed, the first motor is started again to drive the placement plate to flip and extend out of the spray water tank, and then the self-reduction fixes the placement plate, thereby realizing the flipping into the spray water tank while keeping the millimeter-wave radar in a horizontal state.

[0010] Optionally, the self-locking component includes a snap-fit ​​block hinged to the placement plate. The placement plate is provided with a second motor for driving the snap-fit ​​block to rotate. The snap-fit ​​block has a snap-fit ​​groove, and the second connecting rod is provided with a support block.

[0011] By adopting the above technical solution, when the placement plate extends horizontally out of the spray tank, the second motor drives the locking block to rotate, and the support block is locked in the locking groove of the locking block, thereby restricting the flipping of the placement plate.

[0012] Optionally, the detection component includes a support plate, a first rotating rod, and a second rotating rod. The support plate is connected to the spray tank. The support plate is equipped with a third motor, which is connected to the first rotating rod. The first rotating rod is hinged to the second rotating rod. The support plate is provided with a sliding channel, and a sliding shaft is provided in the sliding channel. The second rotating rod is hinged to the sliding shaft, and a thermal imager is connected to the sliding shaft.

[0013] By adopting the above technical solution, the third motor drives the first rotating rod to rotate, the first rotating rod drives the second rotating rod to rotate, and the second rotating rod drives the sliding shaft to move along the sliding channel, thereby enabling the thermal imager to move left and right repeatedly, thus enabling the thermal imager to scan the millimeter-wave radar.

[0014] Optionally, the sliding shaft is connected to an elevated platform, and the thermal imager is mounted on the elevated platform.

[0015] By adopting the above technical solution, the raised plate elevates the thermal imager, allowing the thermal imager's detection port to extend smoothly from the sliding channel.

[0016] Optionally, the gripping assembly includes a robotic arm, a fourth motor, and a first electric cylinder. The fourth motor is mounted on the spray tank and connected to a mounting plate. The first electric cylinder is mounted on the mounting plate and connected to the robotic arm.

[0017] By adopting the above technical solution, the fourth motor drives the mounting plate to rotate, aligning the robotic arm with the first conveyor belt. Then, the first electric cylinder pushes the robotic arm closer to the first conveyor belt to grab the millimeter-wave radar. Next, the fourth motor drives the mounting plate to rotate, causing the robotic arm to rotate onto the placement platform. Then, the robotic arm releases the millimeter-wave radar, and the first electric cylinder drives the robotic arm to retract. After the millimeter-wave radar detection is completed, the first electric cylinder restarts. After the robotic arm grabs the millimeter-wave radar, the fourth motor drives the mounting plate to rotate, and the mounting plate drives the robotic arm to rotate and align with the second conveyor belt. The robotic arm places the detected millimeter-wave radar on the second conveyor belt, thus enabling the automatic rotation of the millimeter-wave radar.

[0018] Optionally, the robotic arm includes a connecting block, a second electric cylinder, and two grippers. The connecting block is mounted on the mounting plate. The first electric cylinder is connected to the connecting block. Telescopic sleeves are provided on both sides of the connecting block. The grippers correspond one-to-one with the telescopic sleeves. One end of each gripper passes through the corresponding telescopic sleeve. A rotating rod is hinged to each of the two grippers. The second electric cylinder is mounted on the connecting block. Both rotating rods are hinged to the lead screw of the second electric cylinder. The two rotating rods are symmetrical about the lead screw of the second electric cylinder.

[0019] By adopting the above technical solution, when the lead screw of the second electric cylinder pushes forward, the second electric cylinder pushes two rotating rods. The angle between the two rotating rods and the lead screw of the second electric cylinder gradually decreases. At this time, the two grippers gradually approach each other, so that the grippers can clamp the millimeter-wave radar.

[0020] Optionally, a drain outlet is provided at the bottom of the spray tank.

[0021] By adopting the above technical solution, the water from the spray test is discharged from the spray water tank through the drain outlet, reducing water overflow.

[0022] Optionally, the bottom surface of the spray tank is a guide surface, and the guide surface is inclined towards the drain outlet.

[0023] By adopting the above technical solution, water can be smoothly discharged from the spray tank through the drain outlet.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The robotic arm picks up the millimeter-wave radar to be tested from the first conveyor belt and places it on the placement plate. The placement plate is flipped into the spray tank for a water spray test. After the water spray is completed, it is then inspected by a thermal imager. Finally, the robotic arm transfers the millimeter-wave radar to the second conveyor belt, thereby realizing the automatic batch airtightness test of the millimeter-wave radar after production.

[0026] 2. The first motor drives the first connecting rod to rotate. The first connecting rod, together with the second connecting rod, keeps the placement plate horizontal and flips it into the spray tank for spraying. After spraying is completed, the first motor is started again to drive the placement plate to flip and extend out of the spray tank. Then, the self-reduction fixes the placement plate, thereby achieving the flipping into the spray tank while keeping the millimeter-wave radar horizontal. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6This application will be described in further detail.

[0035] This application discloses a millimeter-wave airtightness leak detection device.

[0036] like Figure 1 and Figure 2 The millimeter-wave airtightness leak detection device includes a spray tank 1, a first conveyor 2, and a second conveyor 3. The spray tank 1 is a square shell with an opening on one side and a drain outlet 11 at the bottom. The bottom surface of the spray tank 1 is a guide surface 12, which is inclined towards the drain outlet 11. The first conveyor 2 and the second conveyor 3 are each located on one side of the spray tank 1 and connected together. The conveying surfaces of the first conveyor 2 and the second conveyor 3 are flush with the top surface of the spray tank 1. The top of the spray tank 1 is equipped with a gripping component 4 for grabbing the millimeter-wave radar transmitted from the first conveyor 2. The spray tank 1 is equipped with a transmission component 5 for transmitting the millimeter-wave radar into its interior. The spray tank 1 is connected to a detection component 6 for detecting the airtightness of the millimeter-wave radar.

[0037] During the testing of millimeter-wave radar, the first conveyor 2 transports the millimeter-wave radar close to the spray tank 1. The gripping component 4 of the spray tank 1 grips the millimeter-wave radar and transfers it to the conveying component 5. The conveying component 5 then transfers the millimeter-wave radar into the spray tank 1, where the spray tank 1 conducts a water spray test on the millimeter-wave radar. After the conveying component 5 transfers the millimeter-wave radar out of the spray tank 1, the detection component 6 checks the millimeter-wave radar for any water leakage. After the test is completed, the gripping component 4 transfers the millimeter-wave radar to the second conveyor 3 for the next step, thus realizing the automatic batch airtightness testing of the produced millimeter-wave radar.

[0038] like Figure 3 and Figure 4 The conveying assembly 5 includes a placement plate 51, two first connecting rods 52, and two second connecting rods 53. All two first connecting rods 52 and two second connecting rods 53 are hinged within the spray tank 1. One end of each connecting rod extends from the opening of the spray tank 1. The first connecting rods 52 and 53 correspond one-to-one, located on the same side of the spray tank 1, and are parallel to each other. The first connecting rod 52 is located below the second connecting rod 53. The placement plate 51 is an L-shaped plate. The ends of the first connecting rods 52 and 53 extending from the opening of the spray tank 1 are hinged to the placement plate 51. The placement plate 51 is equipped with self-locking elements 55 to restrict the rotation of the first connecting rods 52 and 53.

[0039] The self-locking component 55 includes a snap-fit ​​block 551, which is hinged to one side of the placement plate 51. A second motor 554 is provided on the placement plate 51 and is connected to the snap-fit ​​block 551. A snap-fit ​​groove 552 is provided on the snap-fit ​​block 551. A support block 553 is provided on one of the second connecting rods 53 and is snapped into the snap-fit ​​groove 552.

[0040] like Figure 5 The detection component 6 includes a support plate 61, a first rotating rod 62, and a second rotating rod 63. The support plate 61 is connected to the side of the spray tank 1 with an opening. The support plate 61 is flush with the top of the spray tank 1. A third motor 64 and a sliding channel 65 are arranged sequentially along the length of the support plate 61. The motor shaft of the third motor 64 is hinged to the first rotating rod 62. The end of the first rotating rod 62 away from the third motor 64 is hinged to the second rotating rod 63. The end of the second rotating rod 63 away from the first rotating rod 62 is hinged to a sliding shaft 66. The sliding shaft 66 is connected to a raised plate 69. The raised plate 69 is located in the track of the sliding channel 65. A thermal imager 68 is arranged on the raised plate 69. The thermal imager 68 faces the side of the spray tank 1 with an opening.

[0041] like Figure 4 and Figure 6 The gripping component 4 includes a robotic arm 41, a fourth motor 42, and a first electric cylinder 43. The fourth motor 42 is located at the top center of the spray tank 1. The motor shaft of the fourth motor 42 is connected to a mounting plate 44. The first electric cylinder 43 is mounted on the mounting plate 44. The lead screw of the first electric cylinder 43 is connected to the robotic arm 41.

[0042] The robotic arm 41 includes a connecting block 411, a second electric cylinder 412, and two grippers 413. The connecting block 411 is mounted on the mounting plate 44. The first electric cylinder 43 is connected to the connecting block 411. The connecting block 411 is a square-shaped annular block. The second electric cylinder 412 is located inside the connecting block 411. The lead screw of the second electric cylinder 412 extends out of the connecting block 411. The lead screw of the second electric cylinder 412 is hinged to two rotating rods 415. Telescopic sleeves 414 are provided on both sides of the connecting block 411. The two telescopic sleeves 414 are symmetrical about the lead screw of the second electric cylinder 412, and the extension lines of the two telescopic sleeves 414 intersect the extension line of the lead screw of the second electric cylinder 412 at the same point. The two grippers 413 are L-shaped. Each of the two telescopic sleeves 414 is fitted onto one gripper 413. Each of the two rotating rods 415 is hinged to one gripper 413.

[0043] During the airtightness test of the millimeter-wave radar, the completed millimeter-wave radar is conveyed to the spray tank 1 via the first conveyor belt. The fourth motor 42 starts and drives the mounting plate 44 to rotate, so that the two grippers 413 are aligned with the millimeter-wave radar. Then, the first electric cylinder 43 pushes the connecting block 411 to approach the millimeter-wave radar, and the second electric cylinder 412 pushes the two rotating rods 415 to rotate. The included angle of the two rotating rods 415 becomes smaller, and the two grippers 413 approach each other and clamp the millimeter-wave radar.

[0044] Next, the fourth motor 42 rotates the mounting plate 44, which drives the clamping jaws 413 to align with the placement plate 51. The second electric cylinder 412 retracts, causing the two clamping jaws 413 to move away from each other and placing the millimeter-wave radar on the placement plate 51. The second motor 554 drives the locking block 551 to rotate, causing the locking block 551 to disengage from the support block 553. Then, the first motor 54 is started, which drives the first connecting rod 52 to rotate. The first connecting rod drives the placement plate 51 to gradually flip and enter the spray water tank 1. At the same time, the second connecting rod 53 restricts the tilt of the placement plate 51, keeping the placement plate 51 in a horizontal state as it flips and extends into the spray water tank 1.

[0045] After the spray tank 1 performs a spray test on the millimeter-wave radar, the first motor 54 drives the placement plate 51 to reset, the second motor 554 drives the locking block 551 to re-lock onto the support block 553, and then the third motor 64 drives the first rotating rod 62 to rotate, the first rotating rod 62 drives the second rotating rod 63 to rotate, the second rotating rod 63 drives the sliding shaft 66 to move, the sliding shaft 66 moves along the sliding channel 65 under the limit of the sliding channel 65, the sliding shaft 66 drives the raised plate 69 to move along the sliding channel 65, thereby realizing the thermal imager 68 to perform lateral repeated movement, and thus realize the scanning and detection of the millimeter-wave radar by the thermal imager 68.

[0046] After the test is completed, the first electric cylinder 43 pushes the connecting block 411 to move the gripper 413 close to the millimeter-wave radar. Then, the second electric cylinder 412 drives the gripper 413 to clamp the millimeter-wave radar. The fourth motor 42 drives the mounting plate 44 to rotate, thereby transferring the millimeter-wave radar to the second conveyor 3 and transporting it away, realizing the function of automatically performing batch airtightness testing on the millimeter-wave radars that have been produced.

[0047] The implementation principle of this application embodiment is as follows: the robot arm 41 picks up the millimeter-wave radar to be tested from the first conveyor 2 and places it on the placement plate 51. The placement plate 51 is flipped into the spray water tank 1 for a water spraying test. After the water spraying is completed, it is then inspected by the thermal imager 68. Finally, the robot arm 41 transfers the millimeter-wave radar to the second conveyor 3, thereby realizing the automatic batch airtightness test of the millimeter-wave radar after production.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
