Description

Technical Field

[0001] This utility model relates to the field of crimping devices, and in particular to a rapid crimping device for testing vehicle external detection antennas. Background Technology

[0002] In the precision processes of electronic equipment manufacturing and the complex installation of antenna systems, crimp connectors play a crucial role as connecting components. They are like bridges and links for signal transmission, and the quality of their crimping is of utmost importance. They directly and closely affect whether signal transmission can remain stable and also profoundly influence whether the equipment can maintain reliable stability during long-term operation.

[0003] In existing technologies, when using a rapid crimping device for testing external vehicle detection antennas, metal debris and insulation dust inevitably form on the contact surface after the crimping head completes the mechanical crimping operation between the metal terminal and the cable. If these residues are not cleaned in a timely and effective manner, the previously remaining metal debris will become trapped between the new metal terminal and the cable during the second crimping operation. This will result in an uneven contact surface, making the crimped connection less tight and secure. Consequently, when using the cable in subsequent applications, this not only increases contact resistance but also reduces the stability and reliability of signal transmission, ultimately leading to an increased product defect rate. Therefore, it is necessary to improve the rapid crimping device for testing external vehicle detection antennas to solve the above problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 - Figure 8This utility model provides an embodiment of a rapid crimping device for testing vehicle-mounted detection antennas, comprising a device body 1, a support leg 4 fixedly connected to the device body 1, a crimping assembly disposed on the device body 1, a fixing seat 21 fixedly connected to the device body 1, a first motor 22 fixedly connected to the fixing seat 21, a first threaded rod 23 fixedly connected to the output end of the first motor 22, a sliding seat 24 threadedly connected to the first threaded rod 23, a first telescopic rod 25 fixedly connected to the sliding seat 24, a first connecting plate 26 fixedly connected to one end of the first telescopic rod 25, a transmission assembly disposed on the first connecting plate 26, and a sliding rack 2 slidably connected to the first connecting plate 26. 7. A rotating gear 28 meshing with a sliding rack 27; a nozzle 29 fixedly connected to the rotating gear 28; a first connecting pipe 210 fixedly connected to the first connecting plate 26; an air pump body 211 fixedly connected to the main body 1; a connecting hose 212 fixedly connected between the first connecting pipe 210 and the air pump body 211; a dust collection assembly disposed inside the main body 1; a sliding seat 24 slidably connected to a fixed seat 21; a first connecting plate 26 slidably connected to the sliding seat 24; a nozzle 29 rotatably connected to the first connecting pipe 210; a rotating gear 28 rotatably connected to the first connecting plate 26; and a first threaded rod 23 rotating due to the operation of the first motor 22. 23. Rotating the sliding adjustment seat 24 causes it to slide, and the first telescopic rod 25 pushes the first connecting plate 26 to move. The sliding rack 27 and the rotating gear 28 work together to adjust the nozzle 29 to reciprocate. When the vehicle external detection antenna test quick crimping device is working, the main body 1 of the device is stably placed by the support leg 4. When testing and crimping the vehicle external detection antenna, after the wiring is placed on the main body 1 of the device, the crimping assembly starts to operate to crimp. After completion, the first motor 22 on the fixed seat 21 works to drive the first threaded rod 23 to rotate, so that the sliding seat 24 threaded on the first threaded rod 23 slides along the fixed seat 21, driving the nozzle 29 to move closer to the wiring. Then, the first telescopic rod on the sliding seat 24... When rod 25 is activated, it pushes the first connecting plate 26 to move on the sliding seat 24, adjusting the height of the nozzle 29. Gas is then delivered to the nozzle 29 via the air pump body 211, connecting hose 212, and first connecting pipe 210. The nozzle 29 ejects the gas. When the gas is ejected, the transmission component on the first connecting plate 26 operates, driving the sliding rack 27 to slide on the first connecting plate 26. The sliding rack 27 meshes with the rotating gear 28, causing the rotating gear 28 to rotate. This, in turn, drives the nozzle 29, which is fixed on the rotating gear 28, to reciprocate on the first connecting pipe 210, thereby increasing the gas ejection area, blowing away impurities generated during pressing, and working with the dust collection component to absorb and filter the impurities.

[0027] Please see Figure 1 - Figure 5In this embodiment, the first connecting plate 26 has a limiting groove at the relative position of the sliding rack 27. The sliding rack 27 is slidably connected to the groove. This preferred structure limits and guides the sliding rack 27 through the groove, ensuring that the sliding rack 27 always maintains stable meshing with the rotating gear 28 during reciprocating motion. This avoids inaccurate adjustment of the nozzle 29 angle due to the deviation of the sliding rack 27, and enhances the stability of the device operation. The transmission component includes a second motor 213 fixedly connected to the first connecting plate 26, a rotating disk 214 fixedly connected to the output end of the second motor 213, a fixed rod 215 fixedly connected to the rotating disk 214, and a connecting block 216 fixedly connected to the sliding rack 27. The fixed rod 215 is slidably connected to the connecting block 216. The second motor 213 drives the rotating disk 214 and the fixed rod 215 to rotate. The fixed rod 215 cooperates with the connecting block 216 to drive the sliding rack 27 to slide back and forth.The transmission assembly, driven by the second motor 213, propels the sliding rack 27 in reciprocating linear motion, providing stable and continuous power for the reciprocating rotation of the nozzle 29. This ensures the continuity and uniformity of the nozzle 29 angle adjustment, increases the nozzle 29's air jet range, and thus improves the impurity cleaning effect. The connecting block 216 has a matching groove at the relative position of the fixed rod 215, and the fixed rod 215 is slidably connected to the groove. This structure, through the matching groove, makes the sliding between the fixed rod 215 and the connecting block 216 smoother, reducing friction between them. The frictional resistance and jamming phenomenon during relative motion ensure higher power transmission efficiency of the transmission components, further improving the smoothness of the reciprocating motion of the sliding rack 27. The dust collection component includes a collection hopper 217 fixedly connected inside the device body 1, a fixed box 218 fixedly connected inside the device body 1, a second connecting pipe 219 fixedly connected between the collection hopper 217 and the fixed box 218, a centrifugal fan body 220 disposed inside the device body 1, a sliding frame 221 slidably connected to the fixed box 218, and a second connecting pipe 219 disposed on the sliding frame 217. The dust collection assembly, consisting of a pre-filter plate 222 on the sliding frame 221, a dust filter plate 223 on the sliding frame 221, and an activated carbon filter plate 224 on the sliding frame 221, generates negative pressure through the centrifugal fan body 220. This pressure draws dust, debris, and other impurities generated during the testing process into the fixed box 218 via the collection hopper 217 and the second connecting pipe 219. The debris is then purified through a multi-stage filter system, effectively maintaining a clean testing environment and preventing impurities from affecting the accuracy of antenna testing. The sliding frame 221 has three sections. The 21 are slidably connected to the fixed box 218 in sequence, and the pre-filter plate 222, dust filter plate 223 and activated carbon filter plate 224 are arranged on the three sliding frames 221 in sequence. This arrangement realizes the graded processing of the filtration function. The pre-filter plate 222 intercepts large particles of debris, the dust filter plate 223 filters fine dust, and the activated carbon filter plate 224 adsorbs odors and harmful gases. While improving the filtration effect, the independent sliding frame 221 design makes it easy to disassemble and replace different filter plates individually, reducing maintenance costs and difficulty.

[0028] Please see Figure 1 , Figure 6 - Figure 8In this embodiment, the crimping assembly includes a first fixed bracket 31 fixedly connected to the device body 1, a second telescopic rod 32 fixedly connected to the first fixed bracket 31, a second connecting plate 33 fixedly connected to one end of the second telescopic rod 32, a crimping head body 34 disposed on the second connecting plate 33, a second fixed bracket 35 fixedly connected to the device body 1, a third telescopic rod 36 fixedly connected to the second fixed bracket 35, a rotating bushing 37 rotatably connected to one end of the third telescopic rod 36, a first connecting rod 38 fixedly connected to the rotating bushing 37, a pressing plate 39 fixedly connected to the first connecting rod 38, a guide sleeve 310 fixedly connected to the device body 1, and the first connecting rod 38 slidably connected to the guide sleeve 310. On the 10th, the second connecting plate 33 is slidably connected to the first fixed bracket 31. The second connecting plate 33 is moved by the operation of the second telescopic rod 32, and the rotating bushing 37 is moved by the operation of the third telescopic rod 36. The pressing plate 39 is driven by the third telescopic rod 36 to press the wire, ensuring that the pressing process is stable and accurate, and realizing a reliable connection between the antenna and the test equipment. The guide sleeve 310 has a guide groove at the relative position of the first connecting rod 38. The first connecting rod 38 is slidably connected to the groove. This structure restricts the sliding trajectory of the first connecting rod 38 through the guide groove. After the pressing is completed, the wire needs to be removed. The groove cooperates with the first connecting rod 38 to drive the pressing plate 39 to rotate to both sides so that the staff can remove the wire.

[0029] During the testing and crimping of the external detection antenna, the main body 1 of the device is stably placed by the support leg 4. After the wiring is placed on the main body 1, the third telescopic rod 36 on the second fixed bracket 35 works to push the rotating sleeve 37 to move. The rotating sleeve 37 drives the first connecting rod 38 to slide on the guide sleeve 310. The first connecting rod 38 then drives the pressing plate 39 to move closer to the wiring to crimp it. Then, the second telescopic rod 32 on the first fixed bracket 31 works to push the second connecting plate 33 to slide on the first fixed bracket 31, so that the crimping head body 34 on the second connecting plate 33 moves closer to the wiring and completes the crimping. After the crimping is completed, the third telescopic rod 36 drives the rotating sleeve 37 to reset. Rod 38 slides within the groove of guide sleeve 310, causing pressing plate 39 to rotate to both sides, thus facilitating the removal of wiring by workers. After the wiring is removed, the first motor 22 on the fixed base 21 operates, driving the first threaded rod 23 to rotate, causing the sliding seat 24 threaded onto the first threaded rod 23 to slide along the fixed base 21. The sliding seat 24 drives the first telescopic rod 25, the first connecting plate 26, and the nozzle 29 to move closer to the wiring. Then, the first telescopic rod 25 on the sliding seat 24 operates, pushing the first connecting plate 26 to move on the sliding seat 24, thereby adjusting the height of the nozzle 29 so that it is aligned with the wiring and surrounding area. Then, the air pump body 211 operates, sending gas through the connecting hose 212. The gas is conveyed to the first connecting pipe 210, and then to the nozzle 29. The gas is ejected from the nozzle 29. During the gas ejection process, the transmission assembly is activated synchronously. The second motor 213 operates, driving the rotating disk 214 to rotate. The fixed rod 215 on the rotating disk 214 rotates with the rotating disk 214. The fixed rod 215 slides within the groove of the connecting block 216, thereby causing the connecting block 216 and the sliding rack 27 to reciprocate within the groove of the first connecting plate 26. When the sliding rack 27 slides, it meshes with the rotating gear 28, causing the rotating gear 28 to rotate on the first connecting plate 26. The rotating gear 28, in turn, drives the nozzle 29, which is fixedly connected to it, to reciprocate on the first connecting pipe 210. The gas sprayed from nozzle 29 expands its coverage area, blowing away impurities generated during the pressing process. At the same time, the dust collection component starts working, with the centrifugal fan body 220 generating negative pressure. Under the action of negative pressure, the impurities blown by the gas enter the second connecting pipe 219 through the collection hopper 217, and then enter the fixed box 218 through the second connecting pipe 219. After entering the fixed box 218, the impurities pass through the pre-filter plate 222, dust filter plate 223 and activated carbon filter plate 224 on the three sliding frames 221 in sequence. After multi-stage filtration, the purified air is discharged, while the impurities are intercepted on each filter plate. When it is necessary to clean the filter plates, the sliding frame 221 can be slid out from the fixed box 218 for individual cleaning or replacement.

[0030] Through the above steps, the air pump body 211 works, and the gas is delivered to the nozzle 29 through the connecting hose 212 and the first connecting pipe 210. On this basis, the transmission component works to expand the range of gas ejection. In conjunction with the dust collection component, the impurities are prevented from remaining and affecting the crimping process. This solves the problem that residual debris and dust after crimping will affect the quality of subsequent crimping work and reduce the stability and reliability of signal transmission when the antenna is used.
