RF connector pins are one of the key components of RF connectors. They are usually made of metal materials with excellent conductivity. Their main function is to realize the transmission and connection of RF signals between different devices or components.

[0019] Please see Figures 1-10 The present invention provides a technical solution: A multi-station automatic cutting device for RF connector pins and its control method include a geared motor 1 and a first bracket 2. A feeding and positioning component 5 is rotatably connected to the inner side of the first bracket 2. A support frame 3 is rotatably connected to the outer side of the feeding and positioning component 5 near its rear end. A discharge bin 4 is fixedly connected to the upper end of the support frame 3. A sleeve 9 is fixedly connected to the outer side of the discharge bin 4. A cutting component 6 is attached to the lower end of the support frame 3. A cutting cylinder blade 7 is installed inside the cutting component 6. The feeding and positioning component 5 includes a fixed column 51. An electric hydraulic rod 52 and a guide column 53 are fixedly connected to the inner side of the fixed column 51. A movable column 54 is slidably connected to the outer side of the guide column 53. A material drop groove 55 is opened near the outer side of the movable column 54. A guide hole 56 is opened inside the movable column 54. A column shell 57 is fixedly connected to the rear end of the guide column 53. An insertion hole 58 is opened inside the column shell 57. A sloped pressure block 59 is fixedly connected inside the column shell 57.

[0020] As a further implementation of this solution, the lower end of the geared motor 1 is fixedly connected to the first bracket 2 via a bracket, and the end of the main shaft of the geared motor 1 is fixedly connected to the fixed column 51. Through the above settings, this structural design ensures a stable connection between the geared motor 1 and the fixed column 51. The fixed connection between the bracket and the first bracket 2 enhances the stability of the overall structure, effectively withstands the load during the processing, and improves the operational reliability of the equipment. As a further implementation of this solution, the first bracket 2 is in the shape of a ring structure near the upper end. A bearing is fixedly connected to the inner side of the first bracket 2. The first bracket 2 is rotatably connected to the fixed column 51 through the bearing. Through the above arrangement, the fixed column 51 can rotate smoothly in the first bracket 2, reducing friction, improving the accuracy and flexibility of rotation, and ensuring the stability and accuracy of the processing. As a further implementation of this solution, the support frame 3 is sleeved on the outside of the feeding and positioning assembly 5. A second bracket 8 is fixedly connected to the support frame 3 near the rear end. The shape of the second bracket 8 is the same as that of the first bracket 2. The inner side of the second bracket 8 is rotatably connected to the outer side of the column shell 57. Through the above arrangement, the feeding and positioning assembly 5 provides additional support, which enhances the stability of the overall structure. At the same time, the rotatable connection between the inner side of the second bracket 8 and the column shell 57 ensures the smooth operation of the rotating parts and improves the reliability and service life of the equipment. As a further implementation of this solution, the inner side of the feeding bin 4 is a hollow structure, and the inner side of the feeding bin 4 stores the RF connector pin blanks. The feeding bin 4 is located at the upper end of the movable column 54, and the lower end of the feeding bin 4 is clearance-fitted with the upper end of the movable column 54. Through the above setting, it is convenient to store the RF connector pin blanks, and the clearance fit ensures that the pin blanks can fall smoothly. As a further implementation of this solution, the piston rod of the electro-hydraulic rod 52 is fixedly connected to the movable column 54. A sliding hole is provided on the inner side of the movable column 54. The material drop groove 55 is aligned with the insertion hole 58. A sleeve 9 is fitted on the outer side of the movable column 54. The outer side of the movable column 54 and the inner side of the sleeve 9 are clearance-fitted. Through the above settings, the fixed connection between the piston rod of the electro-hydraulic rod 52 and the movable column 54, as well as the design of the sliding hole, enable the movable column 54 to move precisely, ensuring the accurate positioning of the RF connector pin blank. The sleeve 9 and the clearance fit prevent the pin blank from falling off during processing, thus improving the stability of processing. As a further implementation of this solution, the cutting assembly 6 includes a stepper motor 61. A fixed gear column 62 is fixedly connected to the end of the spindle of the stepper motor 61. A first gear 63 is fixedly connected to the outside of the fixed gear column 62. The outside of the first gear 63 meshes with the outside of multiple second gears 64. The inside of the second gears 64 is fixedly connected to the outside of the cutting barrel cutter 7. The housing of the stepper motor 61 is fixedly connected to the base plate 65 through a bracket. A support plate 66 is fixedly connected to the base plate 65 near the front end. A shaft rotation hole 67 is opened on the inside of the support plate 66. The axis of the support plate 66 is aligned with the axis of the cylindrical housing 57. The inside of the shaft rotation hole 67 is rotatably connected to the outside of the cutting barrel cutter 7. Through the above settings, precise driving of the cutting barrel cutter 7 is achieved, and multiple RF connector pin blanks can be processed simultaneously, improving processing efficiency and adapting to the needs of large-scale production. As a further implementation of this solution, the cutting barrel cutter 7 includes a barrel body 71. A needle inlet groove 72 is opened through the front end of the barrel body 71. A first protruding blade 73 is fixedly connected to the needle inlet groove 72 near the front end. A second protruding blade 74 is fixedly connected to the needle inlet groove 72 near the rear end. A ball bearing 75 is fixedly connected to the outside of the barrel body 71. The barrel body 71 is rotatably connected to the inside of a support plate 66 through the ball bearing 75. The rear end of the barrel body 71 extends out of the outside of a shaft rotation hole 67. With the above configuration, the device can perform various processing operations on the end of the RF connector pin blank, such as cutting and chamfering.

[0021] Workflow: When unloading the RF connector pin blank, the RF connector pin blank is first placed inside the unloading bin 4 through the upper end of the unloading bin 4. The unloading bin 4 falls naturally, and at this time, the opening at the lower end of the unloading bin 4 is aligned with the unloading chute 55. The bottom RF connector pin blank falls into the unloading chute 55, at which point the outer surface of the RF connector pin blank is flush with the outer surface of the movable column 54, so as not to affect the rotation of the movable column 54. The geared motor 1 is started to drive the fixed column 51 to rotate, which in turn drives the entire loading and positioning assembly 5 to rotate. The electric hydraulic rod 52 is powered by a battery and is controlled by Bluetooth using existing technology. The fixed column 51 is... The bearing is rotatably connected inside the first bracket 2, and the column shell 57 is rotatably connected inside the second bracket 8 through the bearing. The first bracket 2 and the second bracket 8 serve to support the overall weight of the feeding and positioning component 5, while not hindering the normal rotation of the feeding and positioning component 5. When the movable column 54 rotates, the RF connector pin blanks inside the feeding bin 4 will fall into the feeding groove 55 one by one until there are RF connector pin blanks in multiple feeding grooves 55. The sleeve 9 can prevent the RF connector pin blanks from detaching from the feeding groove 55. Based on the above principle, the device does not require manual operation when feeding multiple RF connector pin blanks, improving the convenience of feeding. When fixing the RF connector pin blank being fed, the electric hydraulic rod 52 is activated to drive the movable column 54 to move backward. The movable column 54 is slidably connected to the outside of the guide column 53, which limits the movement direction of the movable column 54. The movable column 54 drives the RF connector pin blank inside the dropping groove 55 to move. At this time, the RF connector pin blank is disengaged from the sleeve 9 and inserted into the socket 58. When one-third of the rear end of the RF connector pin blank is inserted into the socket 58, the movable column 54 disengages from the sleeve 9 and enters the column housing 57 near the dropping groove 55. At the same time, the RF connector pin blank is fixed by the pressure of the sloped pressure block 59. When unloading, the movable column 54 is moved to the front end of the sleeve 9, and the RF connector pin will fall off automatically. This process not only prevents the RF connector pin blank from shifting, but also improves the stability of fixing the RF connector pin blank through the pressing action, providing stability for the end cutting of the RF connector pin blank. When cutting the RF connector pin blank, the bottom end of the substrate 65 is fixed to the existing linear module. The linear module controls the cutting assembly 6 and the cutting barrel 7 to move forward as a whole. When the RF connector pin blank contacts the corresponding first protrusion 73, the rapid rotation of multiple barrel bodies 71, the first protrusion 73 and the second protrusion 74 achieves the effect of cutting the end of the RF connector pin blank. The first protrusion 73 can shorten the diameter of the rear end of the RF connector pin blank, and the second protrusion 74 can chamfer the rear end of the RF connector pin blank. When the barrel body 71 rotates, the stepper motor 61 is started to drive the fixed gear column 62 and the first gear 63 to rotate. The first gear 63 drives multiple second gears 64 to rotate, and the second gears 64 drive the corresponding barrel bodies 71 to rotate. The barrel bodies 71 rotate inside the shaft rotation hole 67 through the bearing. Through the above principle, the device can simultaneously and rapidly cut the ends of multiple RF connector pin blanks. This cutting method achieves the effect of batch processing and adapts to the needs of large-scale production.
