[0020] This application provides a coaxial line automatic braiding device and connector processing production line, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. In the following embodiments, the description of each embodiment has its own emphasis. For parts not detailed in one embodiment, please refer to the relevant description of other embodiments.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present embodiment provides a coaxial line automatic braiding device for braiding a coaxial line 1, wherein the coaxial line 1 includes an inner core 11 and a braided layer 12 covering the inner core 11; the device includes: a mounting platform 2, wherein the mounting platform 2 has a first direction X; a chopping and pressing assembly 3, which is arranged on the mounting platform 2, and has a processing through hole 300, wherein the coaxial line 1 passes through the processing through hole 300 along the first direction X, and the chopping and pressing assembly 3 can cut the coaxial line 1 passing through the processing through hole 300, so that part of the braided layer 12 is cut off and the coaxial line 1 is cut off. Part of the inner core 11 is exposed; the pushing braiding component 4 is arranged on the mounting platform 2 and is located on one side of the chopping component 3; the pushing braiding component 4 includes a sleeve 41 and a blowing unit 42 arranged around the sleeve 41; the exposed inner core 11 is passed through the sleeve 41; the inner wall of the sleeve 41 can drive the partially cut braided layer 12 to move away from the inner core 11, and the blowing unit 42 can blow air toward the braided layer 12 while the braided layer 12 moves, so that the braided layer 12 is unfolded in a direction opposite to the first direction X.

[0022] It can be understood that the device of this embodiment can automatically stretch the coaxial line 1 so that the inner core 11 and the braided layer 12 can be unfolded. The specific implementation method includes: first, the coaxial line 1 passing through the processing hole 300 is cut by the chopping component 3, so that part of the braided layer 12 is cut off. At this time, the braided layer 12 changes from a wrapped state to a loose state, thereby exposing part of the inner core 11. Then the coaxial line 1 leaves the processing hole 300, and the sleeve 41 of the braided component 4 is controlled to move into the processing hole 300. At this time, the coaxial line 1 is moved again to the corresponding sleeve, and the coaxial line 1 is controlled to move so that the previously exposed inner core is inserted into the sleeve 41. During the insertion process, since the braided layer 12 is loose, the inner wall of the sleeve 41 can drive the partially cut braided layer 12 to move away from the inner core 11. At the same time, the blowing unit 42 starts to start, and can blow air to the braided layer 12 while it moves, so that the braided layer 12 is unfolded in a direction opposite to the first direction, thereby completing the processing of the braided layer 12. The device of this embodiment can automatically complete the expansion process of the coaxial line, reduce the need for manual operation, and improve work efficiency. The chopping and pressing component 3 can accurately cut the coaxial line 1, ensure the accuracy of the cutting position, and avoid errors that may be caused by manual operation. The braiding component 4 can quickly and evenly expand the braided layer 12 through the synergistic effect of the sleeve 41 and the blowing unit 42, and make the braiding process in one step. By adjusting the airflow intensity of the blowing unit, the expansion force of the braided layer can be controlled, and the braiding wire that falls on the inner core can also be blown away to avoid product short circuit caused by the residual braiding wire.

[0023] In some embodiments, see further Figure 3 , Figure 4 and Figure 5 The blowing unit 42 includes a connecting portion 421, the connecting portion 421 has a first accommodating cavity 420, and the sleeve 41 is inserted into the first accommodating cavity 420; the connecting portion 421 also has an air outlet channel 4210, the air outlet channel 4210 is connected to the first accommodating cavity 420, and the air outlet channel 4210 extends along the first direction X, and the opening of the air outlet channel 4210 faces the woven layer 12.

[0024] It is understandable that the blowing unit 42 includes a connecting portion 421, the connecting portion 421 has a first accommodating cavity 420, and the sleeve 41 is inserted into the first accommodating cavity 420, that is, the sleeve 41 is located inside the first accommodating cavity 420. The connecting portion 421 also has an air outlet channel 4210, which is connected to the first accommodating cavity 420. The air outlet channel 4210 extends along the first direction X, that is, the same as the extension direction of the coaxial line 1. The opening of the air outlet channel 4210 faces the braided layer 12, that is, the airflow of the air outlet channel 4210 can directly act on the braided layer 12. Through the air outlet channel 4210, the device can accurately control the direction and intensity of the airflow, so that the airflow can accurately act on the braided layer 12, thereby realizing the deployment of the braided layer 12. With the opening of the air outlet channel 4210 facing the braided layer, the airflow can directly act on the braided layer 12, providing a more efficient deployment force and accelerating the deployment speed. Since the airflow acts on the braided layer 12 instead of directly contacting the braided layer 12, damage to the braided layer 12 can be avoided, thereby protecting the integrity of the braided layer 12. Figure 4 and Figure 5 For example, the direction in which the braided layer 12 is unfolded is completely the same as the direction of the airflow (the direction of the arrow in the figure), and the airflow direction can be understood as the opposite direction of the first direction X. In the device of this embodiment, the braided layer 12 can be pre-pushed through the inner wall of the sleeve 41 to facilitate the unfolding of the braided layer 12, and then the braided layer 12 is further unfolded under the coordinated action of the blowing unit to achieve the braiding process.

[0025] In some embodiments, see further Figure 1 , Figure 2 and Figure 4 The push-weaving component 4 also includes: a first slider 43, the side of the connecting part 421 away from the braided layer 12 is arranged in the first slider 43, the first slider 43 has an air intake channel 430, and the air intake channel 430 is connected to the first accommodating chamber 420; a first motor 44, the first motor 44 is connected to the first slider 43; a first slide rail 45, the first slide rail 45 is connected to the first slider 43, and the first motor 44 can drive the first slider 43 to move relative to the first slide rail 45, so that the connecting part 421 is arranged in the processing through hole 300, and the sleeve 41 moves in a direction opposite to the first direction X.

[0026] It is understood that, through the coordinated action of the first slider 43 and the first slide rail 45, the first motor 44 controls the movement of the first slider 43, so that the connecting portion 421 can move within the machining hole 300, thereby achieving the expansion of the coaxial line 1. Through the control of the first motor 44, the position of the connecting portion 421 within the machining hole 300 can also be precisely controlled.

[0027] In some embodiments, see further Figure 5 The sleeve 41 has a second accommodating cavity 410 extending along the first direction X, and a portion of the inner core 11 is inserted into the second accommodating cavity 410. A boss 411 is provided in the second accommodating cavity 410, which is connected to the inner wall of the sleeve 41. The boss 411 can limit the position of the inner core 11 when the inner core 11 is inserted into the second accommodating cavity 410. It can be understood that the sleeve 41 has a second accommodating cavity 410 extending along the first direction X, which can accommodate a portion of the inner core 11. This ensures that the inner core 11 maintains a stable position during operation of the device, prevents the inner core 11 from moving or shaking, and maintains the structural integrity of the coaxial line 1. A boss 411 is provided in the second accommodating cavity 410, and the boss 411 is connected to the inner wall of the sleeve 41. When the inner core 11 is inserted into the second accommodating cavity 410, the boss 411 can limit the inner core 11 to ensure that the size of the braided layer 12 after being turned over will not be too large, and the size of the exposed inner core 11 will not be too large, so that the inner core 11 can be installed in an adaptive connector; at the same time, the sleeve 41 can also protect the inner core 11 from being damaged or deformed, thereby protecting the integrity and stability of the inner core 11.

[0028] In some embodiments, see further Figure 4 The push-knitting assembly 4 also includes an air intake unit 46, which is connected to the side of the slider 43 away from the blowing unit 42. Part of the air intake unit 46 is inserted into the first slider 43, and the air outlet end of the air intake unit 46 is connected to the air intake channel 430. It can be understood that the air intake unit 46 is used to deliver gas to the air intake channel 430, and the air intake channel 430 is connected to the blowing unit 42 to ensure the blowing action. The air intake unit 46 can be an electric air pump, etc., or an external air source can be used to directly ventilate the air intake unit 46.

[0029] In some embodiments, see further Figure 1 and Figure 2The mounting platform 2 also has a second direction Y intersecting with the first direction X, and a plurality of push-weaving components 4 are provided, and the plurality of push-weaving components 4 are arranged at intervals along the second direction Y. The device also includes: a second slide rail 51, provided on the mounting platform 2; a second slider 52, connected to the second slide rail 51; a second motor 53, provided on the mounting platform 2 and connected to the second slider 52, and the second motor 53 can drive the second slider 52 to move relative to the second slide rail 51 along the second direction Y; a fixed plate 54, connected to the second slider 52, and a plurality of push-weaving components 4 are provided on the fixed plate 54; the side of the fixed plate 54 away from the second slider 52 is connected to any one of the first slide rail 45 and the first motor 44; the fixed plate 8 drives the push-weaving component 4 to move through the second slider 6, so that the connection part 421 of the blowing unit 42 corresponds to the processed through hole 300 of the chopping component 3 in the first direction X.

[0030] It is understandable that by arranging a plurality of push braiding components 4 spaced apart along the second direction Y, the braided layers of the coaxial lines 1 with different wire diameters can be processed simultaneously, thereby improving the processing efficiency and production capacity of the device. Figure 1 and Figure 2 For example, two push-weaving components 4 are set. When one push-weaving component 4 completes the weaving process, the second slider 52 is driven by the second motor 53 to move along the second direction Y, so that the other push-weaving component 4 can accurately locate and move to the processing hole. The movement switching between different push-weaving components 4 can complete the weaving processing of coaxial cables with different wire diameters; in addition, the fixed plate 54 drives the push-weaving component 4 to move through the second slider 52, so that the connection part 421 of the blowing unit 42 corresponds to the processing hole 300 of the chopping and pressing component 3 in the first direction X, which can achieve precise correspondence between the blowing unit 42 and the chopping and pressing component 3, ensuring the accurate unfolding of the coaxial cable 1.

[0031] In some embodiments, see further Figure 6 The chopping and pressing assembly 3 includes a chopping and pressing tool 31, and the chopping and pressing tool 31 includes: a first mounting plate 311 and a second mounting plate 312 arranged at intervals along the second direction Y, and there is a gap between the first mounting plate 311 and the second mounting plate 312; a first cutting structure 313, which is arranged in the gap and connected to the first mounting plate 311; a second cutting structure 314, which is arranged in the gap and connected to the second mounting plate 312, and the second cutting structure 314 is connected to the first cutting structure 313 on a side away from the second mounting plate 312; the first cutting structure 313 and the second cutting structure 314 jointly define a processing through hole 300, and the first cutting structure 313 can move relative to the second cutting structure 314 to open or close the processing through hole 300.

[0032] It is understood that the edges of the first cutting structure 313 and the second cutting structure 314 have a cutting function, equivalent to the blade of a blade. When the coaxial line 1 passes through the processing hole 300, after the processing hole 300 is closed, the edges of the first cutting structure 313 and the second cutting structure 314 act on the braided layer of the coaxial line 1 to achieve a cutting effect. Subsequently, after the processing hole 300 is opened, the coaxial line 1 can be removed from the processing hole 300.

[0033] In some embodiments, see further Figure 6 The first cutting structure 313 includes a first cutter 3131, a second cutter 3132 and a third cutter 3133 connected in sequence; the side of the first cutter 3131 away from the second cutter 3132 is connected to the first mounting plate 311; the second cutting structure 314 includes a fourth cutter 3141, a fifth cutter 3142 and a sixth cutter 3143 connected in sequence; the side of the fourth cutter 3141 away from the fifth cutter 3142 is connected to the second mounting plate 312 and the third cutter 3133 respectively, and the side of the sixth cutter 3143 away from the fifth cutter 3142 is connected to the first cutter 3131; the first cutter 3131, the second cutter 3132, the third cutter 3133, the fourth cutter 3141, the fifth cutter 3142 and the sixth cutter 3143 together enclose a processing through hole 300. It is understandable that the processing through hole 300 is a hexagonal through hole, and the use of 6 cutters in the chopping tool 31 can achieve the cutting of the braided layer 12 of the coaxial line 1. Of course, in some other ways, the chopping tool 31 is not limited to Figure 6 The processed through hole 300 may also be a triangle, a quadrilateral, a circle or other structures.

[0034] In some embodiments, see further Figure 6 The first mounting plate 311 has a plurality of first mounting grooves 3110, the second mounting plate 312 has a plurality of second mounting grooves 3120, and the chopping tool 31 also includes: a plurality of first drive shafts 315 and a first elastic member 316 sleeved on the first drive shaft 315, the first drive shaft 315 is arranged in the first mounting groove 3110, and is respectively connected to the second cutter 3132 and the third cutter 3133; a plurality of second drive shafts 317 and a second elastic member 318 sleeved on the second drive shaft 317, the second drive shaft 317 is arranged in the second mounting groove 3120, and is respectively connected to the fifth cutter 3142 and the sixth cutter 3143.

[0035] It will be appreciated that when the first and second drive shafts 315, 317 are subjected to external forces, the first and second elastic members 316, 318 will elastically deform, causing the corresponding cutters to move accordingly. By combining the mounting slots and drive shafts, different cutters can be installed as needed to achieve cutting of various shapes and sizes. The presence of the elastic members provides elastic support for the cutters, enabling them to adapt to different workpiece shapes and sizes during the cutting process, improving cutting accuracy and stability. By controlling the movement of the drive shafts, the cutting position and cutting depth can be precisely controlled, thereby improving cutting accuracy and consistency.

[0036] In some embodiments, see further Figure 1 and Figure 2 The chopping and pressing assembly 3 also includes a driving mechanism 32, which includes: a third motor 321; a driving wheel 322 and a driven wheel 323 arranged on one side of the driving wheel 322, the driving wheel 322 is connected to the third motor 321; a transmission belt 324, which is respectively connected to the driving wheel 322 and the driven wheel 323; a transmission shaft 325, which is connected to the driven wheel 323; the side of the transmission shaft 325 away from the driven wheel 323 is respectively connected to the first driving shaft 315 and the second driving shaft 317.

[0037] As will be understood, as the power source of the drive mechanism 32, the third motor 321 is connected to the driving pulley 322 to control the rotation of the driving pulley 322. A transmission belt 324 is connected to the driving pulley 322 and the driven pulley 323, respectively. The movement of the driving pulley 322 is transmitted to the driven pulley 323 via the transmission belt 324. The driven pulley 323 then controls the rotation of the transmission shaft 325, thereby driving the first and second drive shafts 315, 317 to move the corresponding cutters. The drive mechanism 32 transmits power to the first and second drive shafts 315, 317 via the transmission belt 324 and transmission shaft 325, achieving efficient drive and transmission, thereby improving the operating efficiency of the chopping and pressing assembly 3. Controlled by the third motor 321, the movement of the drive mechanism 32 can be precisely controlled, thereby achieving precise control of the cutting position and cutting speed of the chopping and pressing assembly 3, thereby improving the accuracy and consistency of the cutting.

[0038] In some embodiments, the present application further provides a connector processing production line including the coaxial line automatic braiding device of this embodiment. After the coaxial line is braided, the coaxial line automatic braiding device can realize subsequent assembly of the coaxial line and reduce the scrap rate of finished products.

[0039] It can be understood that the meanings of the terms in the embodiments of the present application are the same. For the content that is not described in detail in a certain embodiment, the specific implementation details can refer to the descriptions in other embodiments. The example descriptions and technical effects shown in the aforementioned embodiments can all be implemented accordingly. For the repeated parts, this embodiment will not go into details.
