[0002] A radio frequency connector is an electrical connector mainly used for transmitting microwave signals in high-frequency equipment systems. Its basic structure consists of a housing, an inner core, and an insulator. The housing is usually made of metal materials, and its main function is to provide protection and fixation for the connector, preventing interference or damage between the connector and the external environment. The inner core is generally also made of metal materials and is mainly used to connect the radio frequency coaxial cable and the interface of the equipment to achieve signal transmission. The inner core is generally cylindrical, with one end thick and the other end thin. The gasket is mostly made of plastic materials and is located between the connector and the radio frequency coaxial cable, which can prevent air, water, dust, etc. from entering the inside of the connector and ensure the stability and reliability of the connector.

The sorting and pressing mechanism includes two support seats installed on the top of the receiving plate. The end faces of the two support seats close to the assembly table are jointly installed with a U-shaped frame. Guide plates are installed at both ends of the U-shaped frame. A feeding through groove is jointly formed by the inner wall of the U-shaped frame and the opposite faces of the two guide plates. A limiting component for receiving and limiting the insulator is arranged in the feeding through groove. A downward pushing group for pushing the insulator downward is installed on the support seat. The adjustment and fixation mechanism includes fixing plates uniformly arranged along the circumferential direction of the side wall of the rotating disk. Insertion adjustment holes are opened at the top of the fixing plates, and support cylinders concentric with the insertion adjustment holes are installed at the bottom of the fixing plates. The center of the arc section of the U-shaped frame coincides with the center of each support cylinder rotated to its lower side.

[0019] To better achieve the object of the present invention, the present invention also provides a method for a radio frequency connector assembly device, including the following steps:

[0020] Step 1: Put the outer shell into the first vibrating disk, put the insulator into the second vibrating disk, and put the inner core into the third vibrating disk. The outer shell is conveyed by the first vibrating disk into the second slot of the second support disk. The insulator is conveyed by the second vibrating disk into the first slot of the first support disk. The inner core is conveyed by the third vibrating disk into the fourth slot of the screening disk. The first electric indexing table rotates periodically to drive the screening disk to rotate periodically, and conveys the inner core from the left side of the screening disk to the right side of the screening disk. If the thinner end of the inner core enters the fourth slot of the screening disk, it can be normally conveyed by the screening disk. If the thicker end of the inner core enters the fourth slot of the screening disk, when the screening disk rotates, the thinner end of the inner core at this moment will be lifted by the arc-shaped plate. In the case that the air blowing pipe continuously blows air, the inner core that has not completely entered the fourth slot will be blown off the screening disk and fall back into the third vibrating disk. The inner core is conveyed by the screening disk to the right side of the screening disk and enters the extension channel. At this time, the thicker end of the inner core is the right side of the inner core. The linear feeder below the extension channel assists in conveying the inner core, enabling it to pass through the extension channel and enter the buffer box faster. At this time, the right side of the inner core is the thicker end, and the left side is the thinner end. The thinner left end of the inner core is arranged in the fifth slot on the left side of the buffer box and falls along the buffer box to the rear side of the buffer box;

[0021] Step 2: The output shaft of the driving motor of the linkage pressing device rotates to drive the indexing cam of the cam divider to rotate, causing the output end of the cam divider to rotate. The indexing cam of the cam divider rotates to drive the main rotating plate and the guide wheel to rotate. When the guide wheel contacts the secondary rotating plate, the secondary rotating plate rotates counterclockwise. The counterclockwise rotation of the secondary rotating plate drives the fixed pin to move leftward. The leftward movement of the fixed pin drives the moving plate to move leftward. The leftward movement of the moving plate drives the pressing column to move leftward, and the tension spring undergoes elastic deformation. The leftward movement of the pressing column presses the insulator into the outer shell. The pressing column moves leftward intermittently for continuous assembly. The inner core that falls to the rear side of the buffer box enters the sixth slot of the special-shaped bracket. The output end of the linear module of the inner core pressing device moves rightward to drive the special-shaped bracket to move rightward. The rightward movement of the special-shaped bracket drives one inner core to move rightward and stops at the assembly position of the outer shell and the insulator. At this time, the outer shell and the insulator are just assembled. The thicker end of the inner core is closely attached to the insulator. The output end of the first cylinder extends to drive the push plate to move rightward. The rightward movement of the push plate pushes the inner core to make it enter the insulator. The first cylinder and the linear module return to their original positions, and the installation of the inner core is completed;

[0022] Step 3: The outer shell installed with the insulator and the inner core rotates by an angle through the first support plate and the second support plate and moves to the next working station. The output end of the second cylinder of the detection device extends to drive the pressing head to move towards the outer shell direction, fixing the outer shell at the positions of the first support plate and the second support plate, making the outer shell located at the standard position. Two laser displacement sensors respectively detect the relative positions of the inner core and the insulator to determine whether the product is qualified. If it is unqualified, the driving motor stops rotating. The second electric indexing table rotates 90 degrees to make the third cylinder and the pneumatic gripper rotate to the position of the outer shell. The output end of the third cylinder extends to drive the pneumatic gripper to move towards the outer shell direction. The pneumatic gripper starts to clamp the outer shell. The second electric indexing table rotates back to the initial position, and the pneumatic gripper releases the outer shell. The outer shell falls onto the blanking plate. If it is qualified, the output shaft of the driving motor continues to rotate, causing the outer shell to fall onto the belt conveyor directly below the first support plate and the second support plate. The qualified products are conveyed away by the belt conveyor.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the counterclockwise intermittent rotation of the secondary rotating plate drives the fixed pin to move leftward intermittently. The leftward movement of the fixed pin drives the moving plate to move leftward. The leftward movement of the moving plate drives the pressing column to move leftward, and the tension spring undergoes elastic deformation. The leftward movement of the pressing column presses the insulator and the outer shell for assembly. At this time, the processing station rotates synchronously, and the pressing column moves leftward intermittently for continuous assembly, which is beneficial to the continuous assembly of the insulator and the outer shell while switching workstations, and has a high degree of synchronization;

[0024] 2. Start the conveyance of the inner core through the third vibrating disk. The inner core is conveyed into the fourth slot of the screening disk. The first electric indexing disk rotates periodically to drive the screening disk to rotate periodically, and conveys the inner core from the left side of the screening disk to the right side. If the thinner end of the inner core enters the fourth slot of the screening disk, it can be normally conveyed by the screening disk. If the thicker end of the inner core enters the fourth slot of the screening disk, when the screening disk rotates, the thinner end of the inner core at this moment will be lifted by the arc-shaped plate. When the air blowing pipe continuously blows air, the inner core that has not completely entered the fourth slot will be blown off the screening disk and fall back into the third vibrating disk, which is conducive to quickly screening the conveyance direction of the inner core;

[0025] 3. The inner core that falls to the rear side of the buffer box enters the sixth slot of the special-shaped bracket. The output end of the linear module of the inner core pressing device moves to the right to drive the special-shaped bracket to move to the right. The special-shaped bracket moves to the right to drive an inner core to move to the right and stops at the assembly position of the outer shell and the insulator. At this time, the outer shell and the insulator are just assembled. The thicker end of the inner core is closely attached to the insulator. The output end of the first cylinder extends to drive the push plate to move to the right. The push plate moves to the right to push the inner core so that it enters the insulator, which is conducive to the one-step forming and assembly of the inner core and the insulator and improves the assembly efficiency.

DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. 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.

[0042] The present invention will be further described below with reference to the embodiments.

[0043] In the following description, the "left", "right", "front", "rear", "upper", and "lower" mentioned are oriented in the perspective direction of the front view.

[0044] Embodiment 1: In some embodiments, please refer to Figures 1 - 12 , a radio frequency connector assembly device, including a frame 1, and further including: an inner core feeding device 2, a housing feeding device 3, a linkage pressing device 4, an inner core pressing device 5, and a detection device 6. The linkage pressing device 4 includes: a support frame 41, a cam divider 42, a driving motor 43, a main rotating plate 44, a guide wheel 45, and a secondary rotating plate 46. The support frame 41 is fixedly installed on the front side of the frame 1. The cam divider 42 is installed in the support frame 41. The output end of the cam divider 42 is located on the left side of the support frame 41. The front and rear ends of the rotating shaft of the indexing cam of the cam divider 42 are respectively located on the front and rear sides of the support frame 41. The driving motor 43 is fixedly installed on the rear side wall of the support frame 41 through a bracket. The rear side of the rotating shaft of the indexing cam of the cam divider 42 is fixedly connected to the output shaft of the driving motor 43 through a coupling. The main rotating plate 44 is fixedly installed on the front side of the rotating shaft of the indexing cam. The guide wheel 45 is rotatably connected to one end of the main rotating plate 44 away from the rotating shaft of the indexing cam of the cam divider 42 through a rotating shaft. The secondary rotating plate 46 is rotatably connected to the front side wall of the support frame 41 through a rotating shaft. The lower side of the secondary rotating plate 46 is in close contact with the cam. A strip-shaped opening 47 is provided on the upper side of the secondary rotating plate 46.

[0045] The inner core feeding device 2 is used for feeding the inner core. The housing feeding device 3 is used for feeding the housing and the insulator. The linkage pressing device 4 presses the insulator into the housing. The inner core pressing device 5 presses the inner core into the insulator. The detection device 6 detects the positions of the inner core and the insulator to determine whether the assembled radio frequency connector is qualified.

[0046] The rotation of the output shaft of the driving motor 43 of the linkage pressing device 4 drives the indexing cam of the cam divider 42 to rotate, causing the output end of the cam divider 42 to rotate. The rotation of the indexing cam of the cam divider 42 drives the main rotating plate 44 and the guide wheel 45 to rotate. When the guide wheel 45 contacts the secondary rotating plate 46, the secondary rotating plate 46 rotates counterclockwise intermittently.

[0047] When the rotating shaft of the indexing cam of the indexing cam mechanism 42 rotates once, immediately afterwards, the output end of the indexing cam mechanism 42 rotates by an angle once. There is a time difference between the rotations of the auxiliary rotating plate 46 and the output end of the indexing cam mechanism 42. The time difference is utilized for assembly. The driving motor 43 can rotate intermittently to increase the stopping time of the output end of the indexing cam mechanism 42, facilitating the sequential assembly of the insulator and the inner core.

[0048] The linkage press-fitting device 4 further includes: guide rails 48, sliders 49, a moving plate 410, a pressing column 411, a tension spring 412, and a fixing pin 413.

[0049] The counterclockwise intermittent rotation of the auxiliary rotating plate 46 drives the fixing pin 413 to intermittently move leftward. The leftward movement of the fixing pin 413 drives the moving plate 410 to move leftward. The leftward movement of the moving plate 410 drives the pressing column 411 to move leftward. The tension spring 412 undergoes elastic deformation. The leftward movement of the pressing column 411 performs the press-fitting assembly of the insulator and the outer shell. The intermittent leftward movement of the pressing column 411 enables continuous assembly.

[0050] The linkage press-fitting device 4 further includes: a first support disk 414 and a second support disk 415. The first support disk 414 is fixedly installed at the output end of the indexing cam mechanism 42. The second support disk 415 is fixedly installed on the left side wall of the first support disk 414. A plurality of first slots 416 are arranged in a circumferential array along the center of the first support disk 414 for accommodating the insulator. A step 417 is provided on the left side of the first support disk 414 for accommodating the hexagonal protrusion on the right side of the outer shell. A plurality of second slots 418 are arranged in a circumferential array along the center of the second support disk 415 for accommodating the middle part of the outer shell. A third slot 419 is provided in the middle part of the second support disk 415 for accommodating the threaded area on the left side of the outer shell.

[0051] The outer shell is conveyed into the second slot 418 of the second support disk 415. The insulator is conveyed into the first slot 416 of the first support disk 414. The pressing column 411 moves leftward to push the insulator leftward, pressing the insulator into the outer shell. The restored tension spring 412 that has undergone elastic deformation causes the pressing column to return to its initial position.

[0052] A belt conveyor is fixedly installed on the side of the frame 1. The belt conveyor is located directly below the first support disk 414 and the second support disk 415 and is used to convey the assembled radio frequency connectors.

[0053] The housing feeding device 3 includes: a first vibrating disk 31 and a second vibrating disk 32. The first vibrating disk 31 is fixedly installed on the left rear side of the frame 1, and the second vibrating disk 32 is fixedly installed on the right rear side of the frame 1. Linear feeders are provided at the output ends of the first vibrating disk 31 and the second vibrating disk 32. The output end of the first vibrating disk 31 is closely attached to the second slot 418, and the output end of the second vibrating disk 32 is closely attached to the first slot 416.

[0055] Embodiment 2: In some embodiments, as Figures 1 - 12 shown, as a preferred embodiment of the present invention, the inner core feeding device 2 includes: a third vibrating disk 21, a circular frame 22, a screening disk 23, an arc plate 24, a first electric indexing disk 25, and a blowing pipe 26. The third vibrating disk 21 is fixedly installed on the left front side of the frame 1. The circular frame 22 is fixedly installed on the left front side of the frame 1 through a bracket. The circular frame 22 is located in front of the third vibrating disk 21. The circular frame 22 is inclined towards the third vibrating disk 21, which is beneficial to blowing the inner core away so that it falls into the third vibrating disk 21. The screening disk 23 is rotatably connected to the circular frame 22. A plurality of fourth slots 27 are arranged in a circumferential array along the center of the screening disk 23 on the screening disk 23. The shape of the fourth slots 27 is similar to that of the inner core, and the fourth slots 27 are used to accommodate the inner core. The output end of the third vibrating disk 21 is closely attached to one of the fourth slots 27 on the left side of the screening disk 23. A slope 28 is provided on the left side of the arc plate 24, and the slope 28 is used to assist in lifting the thinner end of the inner core so that it is more easily blown away. The arc plate 24 is fixedly installed on the rear side of the circular frame 22. The first electric indexing disk 25 is fixedly installed on the left front side of the frame 1 through a bracket. The output shaft of the first electric indexing disk 25 is fixedly connected to the lower side of the screening disk 23. The blowing pipe 26 is fixedly installed on the left front side of the frame 1 through a bracket. The blowing pipe 26 is arranged in front of one of the fourth slots 27 on the screening disk 23 close to the third vibrating disk 21 and is used to blow away the inner core that is not completely placed in the fourth slot 27 so that it returns to the third vibrating disk 21 again.

[0056] The third vibrating disk 21 starts to convey the inner core. The inner core is conveyed into the fourth slot 27 of the screening disk 23. The first electric indexing disk 25 rotates periodically to drive the screening disk 23 to rotate periodically, and conveys the inner core from the left side of the screening disk 23 to the right side of the screening disk 23. If the thinner end of the inner core enters the fourth slot 27 of the screening disk 23, it can be normally conveyed by the screening disk 23. If the thicker end of the inner core enters the fourth slot 27 of the screening disk 23, when the screening disk 23 rotates, the thinner end of the inner core at this moment will be lifted by the arc-shaped plate 24. When the air blowing pipe 26 blows air continuously, the inner core that has not completely entered the fourth slot 27 will be blown off the screening disk 23 and fall back into the third vibrating disk 21, which is beneficial to quickly screen the conveying direction of the inner core.

[0057] The inner core feeding device 2 further includes: an extension channel 29 and a buffer box 210. The left side of the extension channel 29 is fixedly installed on the right side of the circular frame 22. The left side of the extension channel 29 is located at one of the fourth slot 27 positions on the right side of the screening disk 23 above the circular frame 22.

A fifth slot 211 is provided on the left side of the buffer box 210 for accommodating the thinner end of the inner core. A linear feeder is provided on the lower side of the extension channel 29.

[0058] The inner core is conveyed by the screening disk 23 to the right side of the screening disk 23 and enters the extension channel 29. At this time, the thicker end of the inner core is the right side of the inner core. The linear feeder on the lower side of the extension channel 29 assists in conveying the inner core, enabling it to pass through the extension channel 29 and enter the buffer box 210 faster. At this time, the right side of the inner core is the thicker end and the left side is the thinner end. The thinner end of the left side of the inner core is arranged in the fifth slot 211 on the left side of the buffer box 210 and falls along the buffer box 210 to the rear side of the buffer box 210, which is beneficial to continuously stack and arrange the inner cores with adjusted postures.

[0059] The inner core pressing device 5 includes: a linear module 51 and a special-shaped bracket 52. The linear module 51 is fixedly installed in the middle of the frame 1. The special-shaped bracket 52 is fixedly installed on the right side of the output end of the linear module 51. A sixth slot 53 is provided on the rear side wall of the special-shaped bracket 52 for accommodating one of the inner cores in the buffer box 210.

[0060] The inner core that falls to the rear side of the buffer box 210 enters the sixth slot 53 of the special-shaped bracket 52. The output end of the linear module 51 of the inner core pressing device 5 moves to the right to drive the special-shaped bracket 52 to move to the right. The special-shaped bracket 52 moves to the right to drive an inner core to move to the right and stops at the position where the outer shell and the insulator are assembled. At this time, the outer shell and the insulator are just assembled, and the thicker end of the inner core is closely attached to the insulator.

[0061] The inner core pressing device 5 further includes: a first cylinder 54 and a push plate 55. The first cylinder 54 is fixedly installed on the left side of the linear module 51, the push plate 55 is fixedly installed at the output end of the first cylinder 54, and the end of the push plate 55 away from the first cylinder 54 is arranged in the sixth slot 53.

[0062] When the output end of the first cylinder 54 extends, it drives the push plate 55 to move to the right. The push plate 55 moves to the right to push the inner core into the insulator. Then, the first cylinder 54 and the linear module 51 return to their original positions, and the installation of the inner core is completed.

[0063] The detection device 6 includes: a second electric indexing table 61, a second cylinder 62, a third cylinder 63, a pressing head 64, a pneumatic gripper 65, a blanking plate 66, and a laser displacement sensor 67.

The two laser displacement sensors 67 are respectively located at the position of the first slot 416 of the first support plate 414 and the position of the second slot 418 of the second support plate 415, and are used to detect the assembled products.

[0064] The housing with the insulator and the inner core installed is rotated by an angle through the first support plate 414 and the second support plate 415 and moves to the next station. The output end of the second cylinder 62 of the detection device 6 extends to drive the pressing head 64 to move towards the housing, fixing the housing at the positions of the first support plate 414 and the second support plate 415, so that the housing is in the standard position. The two laser displacement sensors 67 respectively detect the relative positions of the inner core and the insulator to determine whether the product is qualified. If it is unqualified, the drive motor 43 stops rotating. The second electric indexing table 61 rotates 90 degrees so that the third cylinder 63 and the pneumatic gripper 65 rotate to the position of the housing. The output end of the third cylinder 63 extends to drive the pneumatic gripper 65 to move towards the housing. The pneumatic gripper 65 is activated to clamp the housing. The second electric indexing table 61 rotates back to the initial position, and the pneumatic gripper 65 releases the housing, and the housing falls into the blanking plate 66.

[0065] If it is qualified, the output shaft of the drive motor 43 continues to rotate, causing the housing to fall onto the belt conveyor directly below the first support plate 414 and the second support plate 415. The qualified products are conveyed away by the belt conveyor.

[0066] Example 3: In some embodiments, such as Figures 1 - 12 shown, as a preferred embodiment of the present invention, a method for assembling a radio frequency connector device includes the following steps:

[0067] Step 1: Place the outer shell in the first vibrating bowl 31, place the insulator in the second vibrating bowl 32, and place the inner core in the third vibrating bowl 21. The outer shell is conveyed by the first vibrating bowl 31 into the second slot 418 of the second support plate 415. The insulator is conveyed by the second vibrating bowl 32 into the first slot 416 of the first support plate 414. The inner core is conveyed by the third vibrating bowl 21 into the fourth slot 27 of the screening disc 23. The first electric indexing plate 25 rotates periodically to drive the screening disc 23 to rotate periodically, and conveys the inner core from the left side of the screening disc 23 to the right side of the screening disc 23. If the thinner end of the inner core enters the fourth slot 27 of the screening disc 23, it can be normally conveyed by the screening disc 23. If the thicker end of the inner core enters the fourth slot 27 of the screening disc 23, when the screening disc 23 rotates, the thinner end of the inner core at this moment will be lifted by the arc plate 24. When the air blowing pipe 26 continuously blows air, the inner core that has not completely entered the fourth slot 27 will be blown off the screening disc 23 and fall back into the third vibrating bowl 21. The inner core is conveyed by the screening disc 23 to the right side of the screening disc 23 and enters the extension channel 29. At this time, the thicker end of the inner core is the right side of the inner core. The linear feeder under the extension channel 29 assists in conveying the inner core to make it pass through the extension channel 29 and enter the buffer box 210 faster. At this time, the right side of the inner core is the thicker end and the left side is the thinner end. The thinner left end of the inner core is arranged in the fifth slot 211 on the left side of the buffer box 210 and falls along the buffer box 210 to the rear side of the buffer box 210;

[0068] Step 2: The output shaft of the driving motor 43 of the linkage pressing device 4 rotates to drive the indexing cam of the cam divider 42 to rotate, causing the output end of the cam divider 42 to rotate. The indexing cam of the cam divider 42 rotates to drive the main rotating plate 44 and the guide wheel 45 to rotate. The guide wheel 45 contacts the secondary rotating plate 46, causing the secondary rotating plate 46 to rotate counterclockwise. The counterclockwise rotation of the secondary rotating plate 46 drives the fixed pin 413 to move leftward. The leftward movement of the fixed pin 413 drives the moving plate 410 to move leftward. The leftward movement of the moving plate 410 drives the pressing column 411 to move leftward, and the tension spring 412 undergoes elastic deformation. The leftward movement of the pressing column 411 presses the insulator into the housing. The intermittent leftward movement of the pressing column 411 performs continuous assembly. The inner core that falls behind the buffer box 210 enters the sixth slot 53 of the special-shaped bracket 52. The output end of the linear module 51 of the inner core pressing device 5 moves rightward to drive the special-shaped bracket 52 to move rightward. The rightward movement of the special-shaped bracket 52 drives an inner core to move rightward and stops at the assembly position of the housing and the insulator. At this time, the housing and the insulator are just assembled. The thicker end of the inner core closely adheres to the insulator. The output end of the first cylinder 54 extends to drive the push plate 55 to move rightward. The rightward movement of the push plate 55 pushes the inner core to make it enter the insulator. The first cylinder 54 and the linear module 51 are restored, and the installation of the inner core is completed;

[0069] Step 3: The housing with the insulator and the inner core installed rotates by an angle through the first support disk 414 and the second support disk 415 and moves to the next working station. The output end of the second cylinder 62 of the detection device 6 extends to drive the pressing head 64 to move towards the housing direction, fixing the housing at the positions of the first support disk 414 and the second support disk 415, making the housing located at the standard position. Two laser displacement sensors 67 respectively detect the relative positions of the inner core and the insulator to determine whether the product is qualified. If it is unqualified, the driving motor 43 stops rotating. The second electric indexing table 61 rotates 90 degrees so that the third cylinder 63 and the pneumatic gripper 65 rotate to the housing position. The output end of the third cylinder 63 extends to drive the pneumatic gripper 65 to move towards the housing direction. The pneumatic gripper 65 is activated to clamp the housing. The second electric indexing table 61 rotates back to the initial position, and the pneumatic gripper 65 releases the housing. The housing falls onto the blanking plate 66. If it is qualified, the output shaft of the driving motor 43 continues to rotate, causing the housing to fall onto the belt conveyor directly below the first support disk 414 and the second support disk 415. The qualified products are conveyed away by the belt conveyor.
