Detailed implementation manners

[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0033] As Figures 1 to 10 shown, the embodiment of the present invention provides a vehicle-mounted radar welding system. The vehicle-mounted radar welding system includes a workbench 10, a fixture module 20, a welding module 30, a transfer module 40 and an air tightness detection module 50. The fixture module 20 includes a displacement component 21 and a product fixture 22. The displacement component 21 is arranged on the workbench 10, and the product fixture 22 is arranged on the displacement component 21. The product fixture 22 is movable relative to the workbench 10, and the product fixture 22 is used for placing the product to be welded. The welding module 30 includes a welding head assembly 31 and a welding frame 32. The welding frame 32 is arranged on the workbench 10, and the welding head assembly 31 is slidably arranged on the welding frame 32. The transfer module 40 is used for transferring the product on the product fixture 22 to the air tightness detection module 50.

[0034] In this embodiment, the displacement component 21 is installed on the workbench 10, which can ensure that the product fixture 22 moves precisely on the workbench 10. The product fixture 22 is used to place the on-vehicle radar product to be welded, realizing the fixation and protection of the product, and ensuring the stability and safety of the product during the welding process. Secondly, the welding frame 32 provides a stable operating platform for the welding head component 31. The welding head component 31 slides on the welding frame 32, which can achieve precise welding of the product on the product fixture 22, not only improving the welding accuracy but also greatly enhancing the welding efficiency. Then, the transfer module 40 transfers the welded product from the fixture module 20 to the airtightness detection module 50. The airtightness detection module 50 conducts a comprehensive inspection of the welded product to ensure the welding quality of the products leaving the factory.

[0035] Furthermore, the on-vehicle radar welding system further includes a control module, which can be set as components such as a computer or a processor. The control module is electrically connected to the fixture module 20, the welding module 30, the transfer module 40, and the airtightness detection module 50 to ensure the normal operation of the welding system.

[0036] In summary, the on-vehicle radar welding system provided by the embodiment of the present utility model not only realizes the automation and intelligence of the welding process but also ensures the welding accuracy and quality through precise displacement control, efficient welding technology, and strict airtightness detection, which will greatly improve the manufacturing efficiency and product quality of on-vehicle radars and provide strong support for the development of the modern automotive industry.

[0037] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, the displacement component 21 can at least move in the first direction and the second direction, that is, the displacement component 21 drives the product fixture 22 to move in the first direction and / or the second direction to adjust the welding position for the convenience of the welding module 30 to perform welding, so as to flexibly adjust the position of the product fixture 22 and achieve precise control of the welding position. And this multi-directional movement greatly enhances the flexibility and adaptability of the system, making the welding process more efficient and precise.

[0038] Furthermore, the displacement component 21 includes a slide rail 211, a sliding seat 212, and a first driver 213. The sliding seat 212 is movable relative to the workbench 10 along the slide rail 211. The product fixture 22 is arranged on the sliding seat 212, and the output end of the first driver 213 is connected to the sliding seat 212, thereby realizing precise adjustment and control of the welding position.

[0039] Further, the displacement component 21 further includes a mounting base 214 and a plurality of support rods 215. The support rods 215 are arranged on the workbench 10 in the vertical direction. The mounting base 214 is slidably arranged on the support rods 215. A second driver 217 is arranged on the workbench 10. The output end of the second driver 217 is connected to the mounting base 214. The slide rail 211 is arranged on the mounting base 214 in the horizontal direction.

[0040] In this embodiment, the first driver 213 and the second driver can be set with components such as cylinders and motors. The slide rail 211 is arranged in the horizontal direction, so that the product fixture 22 can move in the horizontal direction; the slide rail 211 is arranged on the sliding seat 212, and the sliding seat 212 can slide relative to the support rods 215, and the support rods 215 are arranged in the vertical direction, so that the product fixture 22 can move in the vertical direction. That is to say, the horizontal direction is the first direction, and the vertical direction is the second direction.

[0041] During the use process, the sliding seat 212 has a first position and a second position on the slide rail 211. In the first position, the product fixture 22 is located outside the welding module 30 to facilitate the loading or unloading of the product; in the second position, the sliding seat 212 drives the product fixture 22 to move below the welding module 30, and then the mounting base 214 drives the slide rail 211 and the sliding seat 212 to move along the support rods 215 towards the welding head assembly 31, so that the radar product on the product fixture 22 is closer to the welding head assembly 31, thereby ensuring that the welding head can accurately contact the product surface and realizing high-quality welding.

[0042] Further, the support rods 215 can be set as linear bearings, which not only enhance the stability and accuracy of the displacement component 21, but also improve its overall performance.

[0043] Such as Figure 2 and Figure 4 As shown, in some embodiments, the displacement component 21 further includes a plurality of displacement rulers 216. The plurality of displacement rulers 216 are correspondingly arranged around the mounting base 214. The displacement rulers 216 are used to collect the movement data of the mounting base 214 along the support rods 215, and can detect the flatness of the radar product to ensure that the detected flatness meets the requirements.

[0044] Further, the displacement rulers 216 can be set to 3. The 3 displacement rulers 216 can be correspondingly arranged at 3 corners of the mounting base 214, so as to monitor the movement of the mounting base 214 in all directions, and thus more accurately judge the flatness of the radar product. When the displacement ruler 216 detects that the flatness does not meet the requirements, the control module can immediately stop the welding operation and prompt the staff to make adjustments, thereby improving the production efficiency and product quality.

[0045] In some embodiments, the welding module 30 further includes a welding base 33. The welding base 33 is disposed at one end of the support rod 215 away from the workbench 10. A welding groove 331 is provided on the welding base 33 for accommodating the product, thereby ensuring the welding quality of the radar product.

[0046] Specifically, the welding base 33 is disposed opposite to the mounting base 214. When the mounting base 214 drives the product fixture 22 upward along the support rod 215 until the product fixture 22 abuts against the welding base 33, the mounting base 214 stops moving. The welding groove 331 exposes only the parts of the radar product that need to be welded, avoiding damage to other components and helping to ensure the welding quality. That is to say, the welding groove 331 can expose only the parts that need to be welded, while the other parts of the radar product are safely hidden in the groove to avoid damage to other components during the welding process.

[0047] Furthermore, the welding module 30 further includes a cooling assembly 34. The cooling assembly 34 includes a gas supply pipe 341 and a jet head 342 located at the end of the gas supply pipe 341. The gas supply pipe 341 is connected to the gas supply module, which can quickly reduce the temperature of the welding area and prevent deformation or cracks caused by overheating. This helps to improve the welding quality and ensure the stability and reliability of the radar product.

[0048] Even further, the gas supply pipe 341 can be set as a corrugated pipe, so as to adjust the position of the jet head 342 according to needs to meet the requirements of different products. The jet head 342 can be set with small and dense spray holes to increase the contact area between the gas and the welding part and improve the cooling efficiency.

[0049] As Figure 2 and Figure 3 shown, in some embodiments, the welding head assembly 31 includes a laser welding head 311 and a laser optical fiber 312. The laser optical fiber 312 is connected to the laser welding head 311, and the laser optical fiber 312 can provide energy for the laser welding head 311.

[0050] Further, the welding module 30 further includes a guide rail 313 and an adjustment screw rod 314. The guide rail 313 is disposed between the welding head assembly 31 and the welding frame 32. The welding frame 32 is disposed on the welding base 33. The adjustment screw rod 314 can be set in a threaded connection with the welding frame 32. One end of the adjustment screw rod 314 is connected to the welding head assembly 31, and a handle 315 can be provided at the other end of the adjustment screw rod 314. The operator can adjust the height of the welding head assembly 31 through the handle 315 to meet the requirements of different products.

[0051] As Figure 1As shown, in some embodiments, the transfer module 40 includes a manipulator 41. The manipulator 41 is disposed on the workbench 10 and can be used to pick up products of a certain type. Moreover, the manipulator 41 has high flexibility and precision, and can adapt to radar products of different sizes and shapes, ensuring that no damage is caused to the products during the transfer process. In addition, the manipulator 41 also has the ability of rapid response and efficient operation, greatly improving the overall efficiency of the production line.

[0052] Furthermore, the transfer module 40 further includes a conveyor belt 42, which undertakes the important task of transferring radar products from one station to another. Before welding starts, the manipulator 41 picks up the radar product from the conveyor belt 42 and accurately places it on the product fixture 22 for subsequent welding operations. Similarly, after welding is completed, the manipulator 41 can also pick up the radar product from the product fixture 22 and place it on the conveyor belt 42 again for transfer to the next station, such as the airtightness detection module 50.

[0053] In addition, it should be noted that the number of the manipulator 41 and the conveyor belt 42 can be set according to needs. In Figure 1 the shown vehicle-mounted radar welding system, one manipulator and one conveyor belt are each set.

[0054] As Figure 5 shown, in some embodiments, the airtightness detection module 50 includes a detection frame 51, a first sealing fixture 52 and a second sealing fixture 53 which are oppositely arranged. The detection frame 51 is disposed on the workbench 10, and the first sealing fixture 52 and / or the second sealing fixture 53 is slidably disposed on the detection frame 51. A receiving space is defined between the first sealing fixture 52 and the second sealing fixture 53 for placing the product.

[0055] In this embodiment, the first sealing fixture 52 is disposed on the workbench 10, and the second sealing fixture 53 is slidably disposed on the detection frame 51. The detection frame 51 is disposed on the workbench 10, providing a stable and adjustable support platform for the first sealing fixture 52 and the second sealing fixture 53. The design of the detection frame 51 allows the fixtures to move and adjust precisely during the detection process, thus ensuring that the product can be accurately and stably placed between the fixtures. The first sealing fixture 52 or the second sealing fixture 53 is slidably disposed on the detection frame 51. Such a design enables the distance between the fixtures to be adjusted to adapt to products of different sizes and shapes. The receiving space defined between the fixtures is used to place the product to be detected, ensuring that the product is in a closed and stable state during the detection process.

[0056] Further, a plurality of positioning members 521 are provided on the first sealing fixture 52. The plurality of positioning members 521 are arranged along the outer periphery of the product to limit the position of the product. And the positions of the positioning members 521 can be set as needed to adapt to different products. Optionally, the positioning members 521 can be set as positioning posts.

[0057] Furthermore, a guide pin 531 is provided on the second sealing fixture 53, and a guide pin hole 522 matching the guide pin 531 is provided on the first sealing fixture 52. The guide pin 531 is used to guide the movement of the second sealing fixture 53 during the closing process of the first sealing fixture 52 and the second sealing fixture 53, so as to ensure that the first sealing fixture 52 and the second sealing fixture 53 can be correspondingly buckled, making the accommodation space completely sealed.

[0058] In some embodiments, the airtightness detection module 50 further includes a sealing ring 54. A sealing groove 523 is provided on the first sealing fixture 52 and / or the second sealing fixture 53. The sealing groove 523 is located on the outer periphery of the accommodation space. The sealing ring 54 is arranged in the sealing groove 523, so as to fill the tiny gap between the fixture and the product, ensure that the outer periphery of the accommodation space is completely sealed, and thus improve the accuracy of detection.

[0059] Further, the sealing groove 523 is provided on the first sealing fixture 52, and the sealing ring 54 can be set as an annular elastic member 554 to ensure that when the fixture is closed, the sealing ring 54 can closely fit on the edge of the product or the corresponding part of the detection interface, forming a closed environment.

[0060] As Figure 6 、 Figure 7 and Figure 8 shown, in some embodiments, the airtightness detection module 50 further includes a plugging assembly 55. The plugging assembly 55 includes a plugging head 551. The plugging head 551 is slidably arranged on the first sealing fixture 52, and the plugging head 551 is used to plug the insertion port of the product.

[0061] Specifically, the shape and size of the plugging head 551 can be designed according to the insertion port of the product to ensure that it can closely fit at the insertion port to form an effective seal. During the airtightness detection process, when the first sealing fixture 52 and the second sealing fixture 53 clamp the product, the plugging head 551 will slide to the insertion port of the product. At this time, the plugging head 551 will closely fit on the insertion port to prevent gas from leaking from the insertion port. Subsequently, gas pressure can be applied to or vacuum can be drawn from the accommodation space to detect the airtightness of the product. Due to the presence of the plugging head 551, the insertion port is also well sealed, so the entire detection process can be more accurate and reliable.

[0062] In some embodiments, the plugging assembly 55 includes a resisting member 552 disposed on the plugging head 551. A pushing block 553 is provided on the second sealing fixture 53. The pushing block 553 is used to push the resisting member 552 to cause the plugging head 551 to slide. The cross-sectional area of the pushing block 553 gradually decreases in the direction from the first sealing fixture 52 to the second sealing fixture 53.

[0063] In this embodiment, the resisting member 552 can be set as a rotating bearing, and the rotating bearing is rotatably disposed on the plugging head 551. During the airtightness detection process, when the first sealing fixture 52 and the second sealing fixture 53 clamp the product, the pushing block 553 will gradually push the resisting member 552. Since the cross-sectional area of the pushing block 553 gradually increases, it will push the plugging head 551 to move towards the insertion port of the product to ensure that the plugging head 551 is gradually pressed against the insertion port during the sliding process, forming a tighter seal.

[0064] Furthermore, the plugging assembly 55 further includes an elastic member 554. The elastic member 554 is connected between the plugging head 551 and the first sealing fixture 52. The plugging head 551 can smoothly slide to the insertion port of the product under the push of the pushing block 553 to form a tight seal. At the same time, after the test is completed, it can automatically reset by means of the deformation force of the elastic member 554 to prepare for the next test.

[0065] That is to say, during the process of the pushing block 553 pushing the plugging head 551 towards the insertion port of the product, the elastic member 554 will be gradually compressed and the amount of deformation will increase. When the airtightness test is completed, the first sealing fixture 52 and the second sealing fixture 53 will separate. At this time, the deformation force accumulated by the elastic member 554 due to previous compression begins to take effect. Under the action of the deformation force of the elastic member 554, the plugging head 551 will gradually disengage from the insertion port and slide along the first sealing fixture 52 to its original position. This process does not require external power and is completely completed by the self-force of the elastic member 554, which is both simple and efficient.

[0066] Optionally, the elastic member 554 can be made of a spring, rubber or other elastic materials. In this embodiment, the elastic member 554 is set as a spring, and two springs are provided. The two elastic members 554 are symmetrically disposed on the left and right sides of the end of the plugging head 551.

[0067] In some embodiments, the plugging assembly 55 further includes a sealing gasket 555. The sealing gasket 555 is disposed at the end of the plugging head 551 to enhance the sealing effect between the plugging head 551 and the insertion port of the product.

[0068] Furthermore, the sealing gasket 555 can be made of a soft, elastic and wear-resistant material, such as rubber, silicone, etc., to ensure a tight fit when the plugging head 551 contacts the insertion port and prevent gas leakage.

[0069] As Figure 5 shown, in this embodiment, the airtightness detection module further includes a sliding assembly 56 for moving the first sealing fixture 52 between a third position and a fourth position. When the first sealing fixture 52 is in the third position, the first sealing fixture and the second sealing fixture are placed in a staggered manner, facilitating the transplanting assembly to place the product on the first sealing fixture. When the first sealing fixture 52 is in the fourth position, the first sealing fixture and the second sealing fixture are arranged opposite to each other, and the second sealing fixture can move towards the first sealing fixture to enclose the accommodation space for product testing.

[0070] Optionally, the sliding assembly 56 may include components such as a slide rail, a driving motor or a driving cylinder, a limit switch, etc., which will not be elaborated here one by one.

[0071] As Figure 6 and Figure 9 shown, in this embodiment, an air supply joint 532 is further provided on the second sealing fixture 532, which can be connected to an external air source to inflate the accommodation space.

[0072] Furthermore, the airtightness detection module further includes a third driver 57, the output end of which is connected to the second sealing fixture, and the third driver is used to reciprocate the second sealing fixture on the detection rack.

[0073] As Figure 10 shown, the airtightness detection module includes a test end 61, a reference end 62, an inflation valve 63, and a differential pressure sensor 65. The product to be tested is placed inside the test end 61, and the inflation valve 63 is used to inflate the test end 61 and the reference end 62. A balance valve 66 is provided between the test end 61 and the reference end 62, and the differential pressure sensor 65 is used to detect the pressure difference between the test end 61 and the reference end 62. The testing process of the radar product may include the following steps:

[0074] Inflation stage: The transfer assembly can place the product on the first sealing fixture 52, and then the second sealing fixture 53 moves towards the first sealing fixture 52 to close the accommodation space. The control module can open the inflation valve 63 to start inflating the accommodation space to a set air pressure, and at the same time, inflate the pressure dividing tank 68 at the reference end 62 to the set air pressure;

[0075] Pressure stabilization stage: After inflation, close the inflation valve 63 to stop air supply, and the air pressure in the accommodation space at the test end 61 enters the pressure stabilization stage. The balance valve 66 is opened, and the test end 61 and the reference end 62 are in a connected state. Accumulate the pressure stabilization duration until the pressure stabilization duration reaches a preset value, then close the balance valve 66 to disconnect the test end 61 and the reference end 62, so as to accelerate the rapid stabilization of the air pressure in the test end 61 and the reference end 62.

[0076] During the test phase, after the voltage stabilization time ends, the pressure difference between the two sides of the test terminal 61 and the reference terminal 62 is read to determine whether there is a leak in the workpiece.

[0077] In some embodiments, the airtightness detection module further includes a pressure dividing valve 67 and a pressure dividing tank 68. The pressure dividing valve 67 and the pressure dividing tank 68 are provided in one-to-one correspondence, and two pressure dividing valves 67 are provided. The two pressure dividing valves 67 are respectively connected to the test terminal 61 and the reference terminal 62. The use of the airtightness detection module further includes the steps of: when the pressure difference between the test terminal 61 and the reference terminal 62 meets the requirements during the test phase, opening the corresponding pressure dividing valves 67 of the test terminal 61 and the reference terminal 62 to zero the differential pressure sensor 65; the gases in the reference terminal 62 and the test terminal 61 are respectively introduced into the corresponding pressure dividing tanks 68, and then the airtightness of the product is judged by measuring the mass of the gas in the pressure dividing tank 68.
