Description

Technical Field

[0001] The present application relates to the technical field of communication connector processing, and in particular to a communication connector processing device. Background Art

[0002] With the rapid development of communication technology, the demand for communication connectors continues to increase, and the requirements for their performance and quality are also getting higher and higher. Common communication connectors mostly include a connecting terminal connected to the wiring harness and a fixed terminal connected to the circuit board, wherein a number of solder pins are provided at the bottom of the fixed terminal, and the solder pins are used to be soldered on the circuit board. When in use, you only need to connect the connecting terminal to the fixed terminal to complete the connection between the wiring harness and the circuit board. However, in order to ensure the quality control of the fixed terminal and facilitate the welding of the solder pins on the circuit board, it is necessary to keep the length of all solder pins at the bottom of the fixed terminal consistent, so the solder pins of the fixed terminal need to be cut.

[0003] In the related art, there is designed a device for processing angle cutting of a communication connector, which includes a frame, an upper cutter block is arranged on the frame, a through hole is provided on the upper cutter block for the welding foot of a fixed terminal to pass through, a lower cutter block is slidably arranged in the horizontal direction below the upper cutter block, a cutting hole is provided on the lower cutter block facing the through hole, and the lower cutter block is driven by a cylinder. When in use, the loading operation is first performed: the fixed terminal is placed on the upper cutter block, and the welding foot passes through the through hole and enters the cutting hole. Next, the foot cutting operation is performed, and the cylinder is controlled to drive the lower cutter block to slide in the horizontal direction, so that the cutting hole and the through hole are misaligned, and the welding foot is cut off. Finally, the unloading operation is performed: the fixed terminal whose foot has been cut is removed. The foot cutting processing of the fixed terminal is completed.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: to complete the pin cutting process of a fixed terminal, three operations are required: loading, pin cutting, and unloading. Among these three operations, there are many actions involving manual participation, and the three operations must be performed in sequence. When a large amount of processing is required, this technology is slow and inefficient for the pin cutting process of the fixed terminal. Summary of the invention

[0005] In order to improve the speed and efficiency of the pin cutting process of the fixed terminal in the communication connector, the present application provides a processing device for the communication connector.

[0006] The present application provides a communication connector processing device that adopts the following technical solution: A processing device for a communication connector comprises a frame, sprockets are rotatably provided at both ends of the frame, a transmission chain is provided between the sprockets, a driving assembly is provided on the frame, and the driving assembly is used to drive the sprockets to rotate; a plurality of upper knife blocks are evenly spaced and fixed on the side walls of the transmission chain, the top of the upper knife block is used to carry a fixed terminal, the upper knife block is provided with a through hole for the welding foot of the fixed terminal to pass through, a lower cutter is fixedly provided on the frame, and the lower cutter can be attached to and slide on the bottom of the upper knife block; a feeding assembly is provided at one end of the frame, and the feeding assembly is used to feed the fixed terminal into the upper knife block, and a receiving box is provided at the other end of the frame.

[0007] By adopting the above technical solution, when the pin cutting process of the fixed terminal is being carried out, the driving component drives the sprocket to rotate, thereby driving the transmission chain to move, and the transmission chain drives the upper knife block to move. The loading component places the fixed terminal on the top of the upper knife block, through the through hole through which the solder pin of the fixed terminal passes. Then, the upper knife block carrying the fixed terminal moves to the lower cutter, and the lower cutter abuts against the bottom of the upper knife block. As the transmission chain continues to move, the solder pin extending through the hole passes through the lower cutter and is cut off by the lower cutter, completing the pin cutting operation. As the transmission chain continues to move, when the upper knife block bypasses one of the sprockets with the transmission chain, the top of the upper knife block faces downward, and the fixed terminal is affected by its own weight and automatically falls and enters the receiving box. During the whole process, multiple upper knife blocks operate in a cycle in sequence, and the loading, pin cutting and unloading operations of different fixed terminals can be carried out simultaneously, thereby improving the speed and efficiency of the pin cutting process of the fixed terminal.

[0008] Preferably, the feeding assembly includes a feeding tube, a release wheel, and a rotating part. The feeding tube is fixedly connected to the frame and arranged in the vertical direction. The inner wall of the feeding tube is adapted to the fixed terminal. The upper knife block can pass directly below the bottom of the feeding tube. A wheel feed groove is provided through the side wall of the feeding tube. The release wheel rotates with the frame, and the peripheral wall of the release wheel extends into the feeding tube through the wheel feed groove. The driving part is used to drive the release wheel to rotate when the upper knife block is located directly below the bottom of the feeding tube.

[0009] By adopting the above technical solution, the fixed terminal is placed from the top of the feeding tube, and the pin is ensured to face downward. The release wheel prevents the fixed terminal from falling directly out of the feeding tube. When the upper knife block is located directly below the bottom of the feeding tube, the rotating part drives the release wheel to rotate, and the release wheel drives the fixed terminal located at the bottom of the feeding tube to move downward, so that it falls on the top of the upper knife block, thereby realizing automatic feeding and improving the efficiency and accuracy of feeding.

[0010] Preferably, the rotating part includes a ratchet, a pawl rod, a reset torsion spring, a pushing pawl, and a limited rotation pawl. The ratchet is coaxial and fixedly connected to the release wheel, one end of the pawl rod is coaxial and rotationally matched with the ratchet, the reset torsion spring is arranged between the pawl rod and the ratchet, one end of the reset torsion spring is fixedly connected to the ratchet, the other end of the reset torsion spring is fixedly connected to the pawl, the other end of the pawl rod rotationally cooperates with the pushing pawl, the pushing pawl resists against the ratchet, the limited rotation pawl rotationally cooperates with the frame, and the limited rotation pawl resists against the ratchet.

[0011] By adopting the above technical solution, when the upper knife block approaches the upper material tube, the claw rod is driven to rotate, and the rotation-limiting pawl prevents the ratchet from rotating with the pushing claw rod. The reset torsion spring between the claw rod and the ratchet begins to deform and accumulate force. When the upper knife block is located directly below the feeding tube, the claw rod is released, and the reset torsion spring drives the claw rod to reset. The pushing pawl on the claw rod resists the ratchet and pushes the ratchet to rotate, thereby driving the release wheel to rotate.

[0012] Preferably, the rotating member also includes a lever and a pulley, wherein the lever is fixedly connected to the claw rod, and the pulley is rotatably arranged on the upper knife block. When the upper knife block approaches the upper material tube, the pulley abuts against the lever and rolls on the lever. When the upper knife block is located directly below the upper material tube, the pulley disengages from the lever and abuts against each other.

[0013] By adopting the above technical solution, when the upper knife block approaches the upper material tube, the pulley and the lever collide and roll on the lever, thereby driving the lever and the claw rod to deflect, and the reset torsion spring begins to accumulate force to achieve loading preparation. When the upper knife block is located directly below the loading tube, the pulley and the lever disengage from the collide, so that the claw rod is reset under the action of the reset torsion spring, and the loading operation is completed. The cooperation of the pulley and the lever makes the loading action more automatic and accurate.

[0014] Preferably, the driving assembly comprises a stepper motor, the stepper motor is fixed on a frame, a driving shaft of the stepper motor is fixedly connected to any sprocket, and the stepper motor drives the sprocket to rotate intermittently.

[0015] By adopting the above technical solution, the stepper motor can control the intermittent rotation of the sprocket, so that when the upper knife block is located directly below the feeding tube, the sprocket can pause for a short time, so that the upper knife block is in a pause state when receiving the fixed terminal, so as to ensure the smooth completion of the feeding action and improve the accuracy and stability of feeding.

[0016] Preferably, two constraint plates are fixedly arranged on the frame, and the two constraint plates are spaced apart from each other in the height direction. The upper knife block can be inserted between the two constraint plates and abut against the two constraint plates at the same time.

[0017] By adopting the above technical solution, the two constraint plates constrain and guide the movement of the upper knife block, making the upper knife block more stable during movement without shaking or offsetting, thereby ensuring the position accuracy of the fixed terminal during the foot cutting process and further improving the processing quality.

[0018] Preferably, a pressure wheel is rotatably provided on the frame, the pressure wheel is located above the lower cutter, and the pressure wheel is used to press the fixed terminal onto the upper cutter block.

[0019] By adopting the above technical solution, the pressure wheel can press the fixed terminal against the upper cutting block, effectively preventing the fixed terminal from shifting or jumping during the cutting process, thereby ensuring the accuracy and stability of the cutting and further improving the processing quality.

[0020] Preferably, a movable groove is provided on the peripheral wall of the pressure wheel, a pressure block is slidably arranged in the movable groove, the pressure block can be abutted against the fixed terminal, a thrust spring is arranged in the movable groove, one end of the thrust spring is connected to the bottom of the movable groove, and the other end of the thrust spring is connected to the pressure block, and the thrust spring drives the pressure block to extend out of the movable groove.

[0021] By adopting the above technical solution, when the pressing wheel needs to press the fixed terminal, the pressing block can adaptively extend out of the movable slot under the action of the thrust spring and resist the fixed terminal. The thrust spring drives the pressing block to extend out of the movable slot, and the pressing block transfers the elastic force of the thrust spring to the fixed terminal, further enhancing the pressing effect on the fixed terminal and improving the stability and accuracy of the foot cutting process.

[0022] Preferably, a driven pulley is rotatably arranged on the frame, a driving pulley is coaxially and fixedly arranged on any of the sprockets, a transmission belt is arranged between the driving pulley and the driven pulley, a reversing gear is coaxially fixed on each of the driven pulley and the pressure wheel, and the two reversing gears are meshed with each other.

[0023] By adopting the above technical solution, when the sprocket rotates, the reversing gear connected to the frame rotation is driven to rotate through the transmission of the driving pulley, the transmission belt and the driven pulley, and the pressure wheel is driven to rotate due to the meshing of the two reversing gears. When the upper cutter block moves, the pressure wheel moves accordingly, and the tangent direction of the bottom of the pressure wheel is consistent with the moving direction of the upper cutter block carrying the fixed terminal. Therefore, during the foot cutting process, the pressure wheel can continuously and effectively press the fixed terminal onto the upper cutter block, thereby improving the stability and reliability of the processing.

[0024] Preferably, a plurality of guide side plates are fixedly provided on the top of the upper blade block, and the ends of the guide side plates facing away from the upper blade block are bent in directions away from each other.

[0025] By adopting the above technical solution, the guide side plate can guide the fixed terminal to automatically align on the upper knife block, which facilitates the accurate placement of the fixed terminal at the specified position of the upper knife block and improves the accuracy of feeding.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up sprockets, transmission chains, lower cutters and multiple upper cutter blocks, the continuous operation of fixed terminal cutting processing is realized, and multiple processes can be carried out simultaneously, which significantly improves the processing speed and efficiency, reduces manual intervention, and improves the degree of automation; 2. By setting the feeding tube, release wheel, ratchet, claw rod, reset torsion spring, push pawl, rotation-limiting pawl, lever and pulley, automatic feeding is realized when the fixed terminal is facing the upper knife block, which improves the feeding efficiency and accuracy; 3. By setting the pressure wheel, movable groove, pressure block, thrust spring, reversing gear, driven pulley, driving pulley and transmission belt, the clamping effect of the fixed terminal during the foot cutting process is enhanced, ensuring the effective coordination between the rotation of the pressure wheel and the movement of the upper knife block, and improving the stability and reliability of the processing.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4This application is described in further detail.

[0033] The present application embodiment discloses a processing device for a communication connector. Figure 1 , which includes a frame 1, which is composed of a bottom plate and a plurality of brackets fixedly connected to the bottom plate. Sprockets 11 are rotatably arranged at both ends of the frame 1, and a transmission chain 12 is arranged between the sprockets 11 for transmission. Specifically, there are two symmetrical sprockets 11 at both ends of the frame 1, and the two sprockets 11 at the same end of the frame 1 are coaxially fixed, and all the sprockets 11 are flush in the height direction. One end of the transmission chain 12 is sleeved on the sprocket 11 at one end of the frame 1, and the other end is sleeved on the sprocket 11 at the other end of the frame 1. The transmission chain 12 in this embodiment adopts a chain with a plurality of metal links hinged to each other.

[0034] Reference Figure 1 and Figure 2 , a driving assembly is provided on the frame 1, and the driving assembly is used to drive the sprocket 11 to rotate. Specifically, the driving assembly includes a stepper motor 3, the stepper motor 3 is fixed on the frame 1, the driving shaft of the stepper motor 3 is fixedly connected to any sprocket 11, and the stepper motor 3 drives the sprocket 11 to rotate intermittently. A plurality of upper knife blocks 2 are evenly spaced and fixed on the side wall of the transmission chain 12. Specifically, the upper knife block 2 is located between the two transmission chains 12, and the upper knife block 2 is fixedly connected to the side walls of the two transmission chains 12 at the same time. The top of the upper knife block 2 is used to carry the fixed terminal 6. A plurality of guide side plates 22 are fixedly provided on the top of the upper knife block 2, and the ends of the guide side plates 22 facing away from the upper knife block 2 are bent in a direction away from each other, so that the fixed terminal 6 can be automatically aligned on the upper knife block 2. In this embodiment, four guide side plates 22 are provided and distributed in a rectangular shape to fit the four sides of the fixed terminal 6.

[0035] Reference Figure 3 and Figure 4 , a through hole 21 is provided on the upper knife block 2 for the welding foot 61 of the fixed terminal 6 to pass through. A lower cutter 13 is fixedly arranged on the frame 1, and the lower cutter 13 can be attached to and slid on the bottom of the upper knife block 2. Specifically, the upper knife block 2 is a straight plate, and the thickness of the upper knife block 2 is consistent with the length of the welding foot 61 after the fixed terminal 6 is cut. Driven by the stepper motor 3, when the upper knife block 2 passes over the lower cutter 13, the lower cutter 13 is attached to and slid on the bottom of the upper knife block 2, and then cuts off the welding foot 61 exposed through the groove. In this embodiment, the caliber of the through hole 21 facing the top side of the upper knife block 2 is larger than the caliber facing the bottom side of the upper knife block 2. The two ends of the through hole 21 have different calibers, which, on the one hand, facilitates guiding the welding foot 61 into the through hole 21, and on the other hand, makes the hole end of the through hole 21 facing the bottom side of the upper knife block 2 become sharp, so as to cut off the welding foot 61 together with the lower cutter 13.

[0036] Reference Figure 4In addition, two constraint plates 14 are fixedly arranged on the frame 1, and the two constraint plates 14 are spaced apart from each other in the height direction. The upper knife block 2 can be inserted between the two constraint plates 14 and abut against the two constraint plates 14 at the same time. The ends of the two constraint plates 14 are bent away from each other to guide the upper knife block 2 to be inserted between the two constraint plates 14. And when the upper knife block 2 is inserted between the two constraint plates 14, the bottom of the upper knife block 2 will contact the lower cutter 13, so as to prevent the upper knife block 2 from shaking, thereby reducing the cutting error.

[0037] Reference Figure 1 A feeding assembly 4 is provided at one end of the frame 1, and the feeding assembly 4 is used to feed the fixed terminal 6 into the upper knife block 2. A receiving box 5 is provided at the other end of the frame 1, and the receiving box 5 is used to receive the fixed terminal 6 dropped from the upper knife block 2. Specifically, a sponge pad or a cushion layer of other soft materials is provided on the inner wall of the receiving box 5.

[0038] In order to achieve orderly loading of fixed terminals 6, refer to Figure 1 and Figure 2 The feeding assembly 4 includes a feeding tube 41, a release wheel 42, and a rotating member 43. The feeding tube 41 is fixedly connected to the frame 1, and the feeding tube 41 is arranged in the vertical direction. The inner wall of the feeding tube 41 is adapted to the fixed terminal 6, and the fixed terminal 6 can only slide in the vertical direction in the feeding tube 41. The upper knife block 2 can pass directly below the bottom of the feeding tube 41. The side wall of the feeding tube 41 is penetrated by a wheel feed groove 44. The release wheel 42 is rotatably matched with the frame 1. The peripheral wall of the release wheel 42 extends into the feeding tube 41 through the wheel feed groove 44 and abuts against the side wall of the fixed terminal 6 in the feeding tube 41. In addition, a rubber layer is also provided on the peripheral wall of the release wheel 42 to protect the fixed terminal 6 and increase the friction between the release wheel 42 and the fixed terminal 6.

[0039] Reference Figure 2 The driving member is used to drive the release wheel 42 to rotate when the upper blade block 2 is located directly below the bottom of the feeding tube 41. Specifically, the rotating member 43 includes a ratchet 431, a claw rod 432, a reset torsion spring, a push pawl 434, a rotation-limiting pawl 435, a lever 436, and a pulley 437. The ratchet 431 is coaxial with the release wheel 42 and fixedly connected, and one end of the claw rod 432 is coaxial with the ratchet 431 and rotates in cooperation. The reset torsion spring is arranged between the claw rod 432 and the ratchet 431, one end of the reset torsion spring is fixedly connected to the ratchet 431, and the other end of the reset torsion spring is fixedly connected to the pawl, and the reset torsion spring is in a relaxed state. The other end of the claw rod 432 is rotationally matched with the push pawl 434, and the push pawl 434 is against the ratchet 431, and the rotation-limiting pawl 435 is rotationally matched with the frame 1, and the rotation-limiting pawl 435 is against the ratchet 431. In addition, torsion springs are provided between the claw rod 432 and the pushing pawl 434 , and between the rotation-limiting pawl 435 and the frame 1 , so as to drive the pushing pawl 434 , the rotation-limiting pawl 435 and the ratchet wheel 431 to abut against each other.

[0040] Reference Figure 2 , the lever 436 is fixedly connected to the claw rod 432, and the pulley 437 is rotatably arranged on the upper knife block 2. Specifically, a vertical rod is fixedly connected to the upper knife block 2, and the pulley 437 rotates on the vertical rod. When the upper knife block 2 approaches the upper material tube 41, the pulley 437 abuts against the lever 436 and rolls on the lever 436. When the upper knife block 2 is located directly below the upper material tube 41, the pulley 437 and the lever 436 are disengaged from abutting each other, and at this time, the stepping motor 3 temporarily stops driving the sprocket 11 to rotate.

[0041] In order to ensure the stability of the fixed terminal 6 when cutting the pin, refer to Figure 4 A pressing wheel 15 is rotatably arranged on the frame 1. The pressing wheel 15 is located above the lower cutter 13. The pressing wheel 15 is used to press the fixed terminal 6 onto the upper cutter block 2. A movable groove 151 is provided on the peripheral wall of the pressing wheel 15. A pressing block 152 is slidably arranged in the movable groove 151. The pressing block 152 can abut against the fixed terminal 6. A thrust spring 153 is arranged in the movable groove 151. One end of the thrust spring 153 is connected to the bottom of the movable groove 151, and the other end of the thrust spring 153 is connected to the pressing block 152. The thrust spring 153 drives the pressing block 152 to extend out of the movable groove 151. A driven pulley 17 is rotatably provided on the frame 1, a driving pulley 111 is coaxially and fixedly provided on any sprocket 11, a transmission belt 112 is provided between the driving pulley 111 and the driven pulley 17, a reversing gear 16 is coaxially fixed on each of the driven pulley 17 and the pressure wheel 15, and the two reversing gears 16 are meshed with each other.

[0042] The implementation principle of the processing device of a communication connector in the embodiment of the present application is as follows: when the pin cutting processing of the fixed terminal 6 is performed, the stepper motor 3 drives the sprocket 11 to rotate intermittently, thereby driving the transmission chain 12 to move, and the upper half of the transmission chain 12 drives the upper knife block 2 to move from the feeding assembly 4 to the lower cutter 13. In this process, when the upper knife block 2 moves and approaches the feeding tube 41, the pulley 437 abuts against the lever 436 and rolls on the lever 436, so that the claw rod 432 deflects, the rotation-limiting ratchet 435 prevents the ratchet 431 from rotating with the pushing claw rod 432, and the reset torsion spring between the claw rod 432 and the ratchet 431 begins to deform and accumulate force. When the upper cutter block 2 is located directly below the bottom of the feeding tube 41, the stepper motor 3 stops briefly, and the upper cutter block 2 also stops briefly. At this time, the pulley 437 and the lever 436 are disengaged from each other, and the reset torsion spring drives the claw rod 432 to reset. The push pawl 434 on the claw rod 432 presses against the ratchet 431 and pushes the ratchet 431 to rotate, thereby driving the release wheel 42 coaxially fixed with the ratchet 431 to rotate. The rotation of the release wheel 42 drives the fixed terminal 6 at the bottom of the feeding tube 41 to move downward, so that the fixed terminal 6 falls on the top of the upper cutter block 2. The guide side plate 22 at the top of the upper cutter block 2 helps the fixed terminal 6 to automatically align, ensuring that the welding foot 61 enters the through slot. In this way, the feeding action is completed.

[0043] Then, the stepper motor 3 continues to run, and the upper cutter block 2 carrying the fixed terminal 6 continues to move with the transmission chain 12, and begins to enter between the constraint plates 14. When it moves to the lower cutter 13, the lower cutter 13 fits with the bottom of the upper cutter block 2. As the transmission chain 12 continues to move, the welding foot 61 extending through the hole 21 passes over the lower cutter 13. Since the hole end of the hole 21 toward the bottom side of the upper cutter block 2 is sharper, and the lower cutter 13 fits and slides with the bottom of the upper cutter block 2, the lower cutter 13 and the upper cutter block 2 cut off the part of the welding foot 61 extending through the hole 21 together, completing the foot cutting operation. And in this process, the driving pulley 111 on the sprocket 11 drives the driven pulley 17 to rotate through the transmission belt 112. Since the driven pulley 17 is meshed with the reversing gear 16 on the pressure wheel 15, the pressure wheel 15 rotates accordingly. When the fixed terminal 6 moves to the bottom of the pressing wheel 15, the pressing block 152 in the movable groove 151 on the peripheral wall of the pressing wheel 15 extends out under the action of the thrust spring 153, pressing the fixed terminal 6 against the upper knife block 2 to ensure the stability of the fixed terminal 6 during the pin cutting process. In this way, the pin cutting action is automatically completed.

[0044] Finally, as the transmission chain 12 continues to move, when the upper cutter block 2 goes around the sprocket 11 with the transmission chain 12, the top of the upper cutter block 2 faces downward, and the fixed terminal 6 automatically falls and enters the receiving box 5 under the influence of its own weight. The unloading operation is automatically completed. During the whole process, multiple upper cutter blocks 2 operate in a cycle in sequence, and the loading, cutting and unloading operations of different fixed terminals 6 can be performed simultaneously, and the required degree of manual participation is low, which improves the speed and efficiency of the fixed terminal 6 cutting processing.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
