A straightening device for processing a communication connector and a straightening method thereof

Abstract

This invention relates to the field of communication connector processing technology, and provides a straightening device and method for processing communication connectors, including a base and a support, with a conveying structure fixed to the top of the base. The invention incorporates a cutting mechanism. When the second transmission wheel drives the turntable to rotate, the turntable drives the movable frame to rotate. The movable frame moves outside the fixed rod, while the fixed rod drives the movable seat to reciprocate. The stability of the movable seat during movement is enhanced by the sliding seat and slide rail. When the turntable drives the fixed column downwards via the movable frame, the fixed column drives the reset baffle downwards, causing the movable rod to drive the cutting blade to cut the workpiece. After the cutting blade completes the cutting, the turntable continues to rotate, driving the movable frame upwards. Simultaneously, the spring force of the reset spring pushes the movable rod upwards to reset, returning the cutting blade to its original position. As the turntable continues to rotate, the cutting blade reciprocates, coordinating with the constant-speed feeding of the workpiece, thereby achieving continuous, precise, and fixed-distance cutting.

Description

Technical Field

[0001] This invention relates to the field of communication connector processing technology, and in particular to a straightening device and straightening method for communication connector processing. Background Technology

[0002] As a core component for signal transmission in communication equipment, the straightness of the pins and metal leads of a communication connector directly affects the insertion and removal accuracy, contact stability, and signal transmission effect. During the manufacturing process of a communication connector, it is necessary to straighten the metal leads to ensure accurate alignment and smooth insertion and removal. Therefore, a straightening device and straightening method for communication connector manufacturing are used. To this end, patent CN117225998A discloses a metal rod straightening device, including a base, a longitudinal clamping unit, a transverse clamping unit, a support unit, and a drive unit. The curved part of the rod to be processed hangs down under the action of gravity and passes through the longitudinal clamping unit to limit the position of the rod to be processed. The transverse clamping unit is used to limit the position of the rod to be processed and includes two relatively movable clamping plates. The support unit is used to straighten the curved part of the rod to be processed. The two clamping plates can move up and down relative to each other through the drive unit. The present invention can limit the vertical and lateral positions of the rod to be processed through the cooperation of two first positioning wheels and two second positioning wheels. The two clamping plates can further limit the lateral positions of the rod to be processed. The support unit can lift the curved part of the rod to be processed to achieve the effect of straightening the rod to be processed in one go. Although the metal rod straightening device mentioned above can achieve the effect of straightening the rod to be processed in one go, its applicability is low because it is inconvenient to cut at a fixed distance and it is difficult to ensure dimensional accuracy and consistency. Summary of the Invention

[0003] The purpose of this invention is to provide a straightening device and method for processing communication connectors, so as to solve the defect of existing straightening devices for processing communication connectors that are inconvenient for fixed-distance cutting.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a straightening device for processing communication connectors, comprising a base and a bracket; A conveying structure is fixed to the top of the base, a straightening structure is fixed to one side of the top of the base, and a bracket is fixed to the other side of the top of the base. A cutting mechanism is provided on one side of the top of the bracket; The cutting mechanism includes a connecting shaft passing through the top of the support. A turntable is fixed to one end of the connecting shaft, and a movable frame is fixed to one side of the turntable. A fixed rod passes through the interior of the movable frame, and movable seats are fixed to both ends of the fixed rod. A knife groove is formed on the top of the movable seat at the bottom end of the fixed rod, and guide grooves are formed inside the movable seats on both sides of the knife groove.

[0005] Preferably, the conveying structure includes a fixed frame, a first conveying roller, an electric push rod, a drive motor, a second conveying roller, a first transmission wheel, a movable frame, a guide rod, a second transmission wheel, and a transmission belt. The fixed frame is fixed to the top of the base, and the bottom of the fixed frame is provided with the first conveying roller. A drive motor is installed on the outer wall of the fixed frame at one end of the first conveying roller, and the other end of the first conveying roller extends to the outside of the fixed frame and is fixed with the first transmission wheel. An electric push rod passes through the top of the fixed frame, and a movable frame is fixed to the bottom of the electric push rod. The bottom of the movable frame is rotatably connected to the second conveying roller. Guide rods pass through the interior of the fixed frames on both sides of the electric push rod. A transmission belt is sleeved on the outer side of the first transmission wheel, and a second transmission wheel passes through one side of the inside of the transmission belt.

[0006] Preferably, one end of the first conveying roller extends to the outside of the fixed frame and is fixedly connected to the output end of the drive motor, and one side of the second transmission wheel is fixedly connected to one end of the connecting shaft. When the first conveying roller rotates, it drives the second transmission wheel to rotate through the first transmission wheel and the transmission belt. At the same time, the friction force drives the workpiece at its top to move forward. At this time, the friction force of the workpiece drives the second conveying roller to rotate synchronously. Under the action of the second conveying roller and the first conveying roller, the workpiece is clamped and transported synchronously, avoiding the workpiece from shifting during transport.

[0007] Preferably, the guide rod and the fixed frame are configured as a sliding structure, with the bottom end of the guide rod fixedly connected to the top end of the movable frame. When the electric push rod drives the movable frame to rise and fall, the stability of the movable frame during movement is enhanced under the action of the guide rod. The moved movable frame will drive the second conveying roller to move, thereby facilitating the adjustment of the gap between the second conveying roller and the first conveying roller, ensuring that the first and second conveying rollers are in close contact with the workpiece surface, without slipping or damaging the workpiece, thus facilitating stable conveying of the workpiece.

[0008] Preferably, the straightening structure includes a fixed frame, a threaded column, a handwheel, a first straightening wheel, a second straightening wheel, a movable seat, and a slide bar. The fixed frame is fixed to one side of the top of the base. The first straightening wheel is rotatably connected to one side of the bottom of the fixed frame. The threaded column passes through the top of the fixed frame. The handwheel is fixed to the top of the threaded column. The movable seat is rotatably connected to the bottom of the threaded column. The second straightening wheel is rotatably connected to one side of the movable seat. Slide bars pass through both sides of the interior of the movable seat. When the threaded column drives the movable seat to move outside the slide bar, the stability of the movable seat during movement is enhanced under the action of the slide bar. The moved movable seat will drive the second straightening wheel to move, thereby facilitating the adjustment of the gap between the second straightening wheel and the first straightening wheel, thus adapting to slender workpieces of different diameters.

[0009] Preferably, the threaded column and the fixed frame are designed with a threaded connection, the movable seat and the slide rod form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the fixed frame. When the workpiece passes through the staggered first and second straightening wheels at a constant speed, under the action of the first and second straightening wheels, the workpiece will be subjected to continuous extrusion forces from the horizontal and vertical directions, and its bent parts will be gradually straightened, thereby achieving the straightening of the workpiece.

[0010] Preferably, a fixing post is fixed to one side of the bottom end of the movable frame, a mounting bracket is fixed to the top of the movable seat above the knife groove, a movable rod passes through the top of the mounting bracket, a cutting blade is fixed to the bottom end of the movable rod, a reset baffle is fixed to the top end of the movable rod, a reset spring is sleeved on the outer side of the movable rod at the bottom end of the reset baffle, a slide block is fixed to one side of the movable seat, and a slide rail passes through one side of the inner side of the slide block.

[0011] Preferably, the movable frame and the fixed rod form a sliding structure, and the slide block and the slide rail form a sliding structure, with one side of the slide rail fixedly connected to one side of the bracket. When the second transmission wheel drives the turntable to rotate via the connecting shaft, the turntable drives the movable frame to rotate, and the movable frame moves up and down on the outside of the fixed rod. At the same time, the fixed rod drives the movable seat to move back and forth. Under the action of the slide block and the slide rail, the stability of the movable seat during movement is enhanced.

[0012] Preferably, the movable rod and the mounting frame are configured as a sliding structure, and the bottom end of the return spring is fixedly connected to the top end of the mounting frame. When the turntable moves the fixed column downward through the movable frame, the fixed column will cause the return baffle to press down, causing the movable rod to drive the cutting blade to cut the workpiece. After the cutting blade completes the cutting, the turntable continues to rotate, causing the movable frame to move upward. At the same time, the elastic force of the return spring pushes the movable rod upward to reset, causing the cutting blade to disengage from the blade groove and return to the initial standby position. As the turntable continues to rotate, the cutting blade reciprocates, coordinating with the constant speed feeding of the workpiece, thereby achieving continuous and precise cutting at a fixed distance.

[0013] A straightening method for a straightening device used in the processing of communication connectors includes the following steps: S1. First, the workpiece is passed through the top of the first straightening wheel and the first conveying roller in sequence, and then through the inside of the guide groove. At this time, the handwheel is turned, and the handwheel will drive the threaded column to rotate inside the fixed frame. The threaded column will drive the movable seat to rise and fall. At the same time, the movable seat will move outside the slide bar. Under the action of the slide bar, the stability of the movable seat during movement is enhanced. After the movable seat moves, it will drive the second straightening wheel to move, so as to facilitate the adjustment of the gap between the second straightening wheel and the first straightening wheel, thereby adapting to slender workpieces of different diameters. S2. Start the electric push rod to drive the movable frame to rise and fall. The movable frame will drive the guide rod to move inside the fixed frame. Under the action of the guide rod, the stability of the movable frame during movement is enhanced. After the movable frame moves, it will drive the second conveyor roller to move, so as to facilitate the adjustment of the gap between the second conveyor roller and the first conveyor roller, ensuring that the first and second conveyor rollers are in close contact with the workpiece surface, without slipping or damaging the workpiece, thus facilitating stable conveying of the workpiece. S3. Start the drive motor to make the first conveyor roller rotate at the bottom of the fixed frame. The first conveyor roller will drive the second conveyor roller to rotate through the first transmission wheel and the transmission belt. At the same time, the workpiece at the top of the first conveyor roller will move forward due to friction. At this time, the friction of the workpiece will drive the second conveyor roller to rotate synchronously. Under the action of the second conveyor roller and the first conveyor roller, the workpiece is clamped and transported synchronously to avoid the workpiece from shifting during transport. The transported workpiece will drive the first straightening wheel and the second straightening wheel to rotate. When the workpiece passes through the interlaced first straightening wheel and the second straightening wheel at a constant speed, the workpiece will be subjected to continuous extrusion force from the horizontal and vertical directions under the action of the first straightening wheel and the second straightening wheel. Its curved parts are gradually straightened, thereby straightening the workpiece. S4. When the second transmission wheel rotates, it drives the turntable to rotate via the connecting shaft. The turntable drives the movable frame to rotate, and the movable frame moves up and down on the outside of the fixed rod. At the same time, the fixed rod drives the moving seat to move back and forth. The moving seat drives the slide to move on one side of the slide rail. Under the action of the slide and the slide rail, the stability of the moving seat during movement is enhanced. When the turntable drives the fixed column to move downward via the movable frame, the fixed column drives the reset baffle to press down. At this time, the reset spring is compressed. The reset baffle drives the cutting blade to cut the workpiece via the movable rod. After the cutting blade completes the cutting, the turntable continues to rotate, driving the movable frame to move upward. At this time, the fixed column separates from the reset baffle. Under the elastic force of the reset spring, it pushes the movable rod upward to reset, causing the cutting blade to leave the blade groove and return to the initial standby position. As the turntable continues to rotate, the cutting blade performs reciprocating motion, which, in conjunction with the constant speed feeding of the workpiece, achieves continuous and precise cutting at a fixed distance.

[0014] The present invention provides a straightening device and method for processing communication connectors, the advantages of which are: With a cutting mechanism, when the second transmission wheel drives the turntable to rotate via the connecting shaft, the turntable drives the movable frame to rotate. The movable frame moves up and down on the outside of the fixed rod, while the fixed rod drives the movable seat to move back and forth. The stability of the movable seat during movement is enhanced by the sliding seat and slide rail. When the turntable drives the fixed column to move downward via the movable frame, the fixed column drives the reset baffle to press down, causing the movable rod to drive the cutting blade to cut the workpiece. After the cutting blade completes the cutting, the turntable continues to rotate, driving the movable frame to move upward. At the same time, the elastic force of the reset spring pushes the movable rod upward to reset, causing the cutting blade to leave the blade groove and return to the initial standby position. As the turntable continues to rotate, the cutting blade reciprocates, which, combined with the constant speed feeding of the workpiece, achieves continuous and precise cutting at a fixed distance. With a conveying structure, when the first conveying roller rotates, it drives the second conveying roller to rotate via the first transmission wheel and the transmission belt. Simultaneously, the friction force drives the workpiece at its top to move forward. At this time, the friction force of the workpiece drives the second conveying roller to rotate synchronously. Under the action of the second and first conveying rollers, the workpiece is clamped and conveyed synchronously, preventing the workpiece from shifting during conveying. When the electric push rod drives the movable frame to rise and fall, the stability of the movable frame during movement is enhanced by the guide rod. The moved movable frame will drive the second conveying roller to move, thereby facilitating the adjustment of the gap between the second and first conveying rollers. This ensures that the first and second conveying rollers are in close contact with the workpiece surface, preventing slippage and damage to the workpiece, thus facilitating stable conveying of the workpiece. By incorporating a straightening structure, when the threaded column drives the movable seat to move outside the slide bar, the stability of the movable seat during movement is enhanced under the action of the slide bar. The moved movable seat will then drive the second straightening wheel to move, thereby facilitating the adjustment of the gap between the second straightening wheel and the first straightening wheel, thus adapting to slender workpieces of different diameters. When the workpiece passes through the interlaced first and second straightening wheels at a constant speed, it will be subjected to continuous extrusion forces from both the horizontal and vertical directions under the action of the first and second straightening wheels, and its bent parts will be gradually straightened, thereby achieving the straightening of the workpiece.

Under the action of the slide bar 37, the stability of the movable seat 36 during movement is enhanced. After the movable seat 36 moves, it will drive the second straightening wheel 35 to move, thereby facilitating the adjustment of the gap between the second straightening wheel 35 and the first straightening wheel 34, so as to adapt to slender workpieces of different diameters. When the workpiece passes through the interlaced first straightening wheel 34 and second straightening wheel 35 at a constant speed, under the action of the first straightening wheel 34 and the second straightening wheel 35, the workpiece will be subjected to continuous extrusion force from the horizontal and vertical directions, and its bent parts will be gradually straightened, thereby realizing the straightening of the workpiece.

[0022] A bracket 4 is fixed to the other side of the top of the base 1. A cutting mechanism 5 is provided on one side of the top of the bracket 4.

[0023] Reference Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, when the second transmission wheel 29 drives the turntable 51 to rotate via the connecting shaft 57, the turntable 51 drives the movable frame 52 to rotate. The movable frame 52 moves up and down on the outside of the fixed rod 53, while the fixed rod 53 drives the movable seat 54 to move back and forth. The movable seat 54 drives the slide 55 to move on one side of the slide rail 56. Under the action of the slide 55 and the slide rail 56, the stability of the movable seat 54 during movement is enhanced. When the turntable 51 drives the fixed column 59 to move downward via the movable frame 52, the fixed column 59 drives the reset baffle 510 to press down. At this time, the reset spring 5 When 11 is compressed, the reset baffle 510 will drive the cutting blade 513 to cut the workpiece through the movable rod 512. After the cutting blade 513 completes the cutting, the turntable 51 continues to rotate, driving the movable frame 52 to move upward. At this time, the fixed column 59 separates from the reset baffle 510. Under the elastic force of the reset spring 511, it will push the movable rod 512 to reset upward, so that the cutting blade 513 disengages from the blade groove 514 and returns to the initial standby position. As the turntable 51 continues to rotate, the cutting blade 513 performs reciprocating motion, which, in conjunction with the constant speed feeding of the workpiece, achieves continuous and precise cutting at a fixed distance.

[0024] A straightening method for a straightening device used in the processing of communication connectors includes the following steps: S1. First, the workpiece is passed through the top of the first straightening wheel 34 and the first conveying roller 22 in sequence, and then through the inside of the guide groove 515. At this time, the handwheel 33 is turned, and the handwheel 33 will drive the threaded column 32 to rotate inside the fixed frame 31. The threaded column 32 will drive the movable seat 36 to rise and fall. At the same time, the movable seat 36 will move outside the slide bar 37. Under the action of the slide bar 37, the stability of the movable seat 36 during movement is enhanced. After the movable seat 36 moves, it will drive the second straightening wheel 35 to move, so as to facilitate the adjustment of the gap between the second straightening wheel 35 and the first straightening wheel 34, thereby adapting to slender workpieces of different diameters. S2. Start the electric push rod 23, which drives the movable frame 27 to rise and fall. The movable frame 27 will drive the guide rod 28 to move inside the fixed frame 21. Under the action of the guide rod 28, the stability of the movable frame 27 during movement is enhanced. After moving, the movable frame 27 will drive the second conveying roller 25 to move, thereby facilitating the adjustment of the gap between the second conveying roller 25 and the first conveying roller 22. This ensures that the first conveying roller 22 and the second conveying roller 25 are in close contact with the workpiece surface, without slipping or damaging the workpiece, thus facilitating stable conveying of the workpiece. S3. Start the drive motor 24 to make the first conveying roller 22 rotate at the bottom of the fixed frame 21. The first conveying roller 22 will drive the second conveying roller 29 to rotate through the first transmission wheel 26 and the transmission belt 210. At the same time, the workpiece at the top of the roller will move forward due to friction. At this time, the friction of the workpiece will drive the second conveying roller 25 to rotate synchronously. Under the action of the second conveying roller 25 and the first conveying roller 22, the workpiece is clamped and transported synchronously to avoid the workpiece from shifting during transport. The transported workpiece will drive the first straightening wheel 34 and the second straightening wheel 35 to rotate. When the workpiece passes through the interlaced first straightening wheel 34 and the second straightening wheel 35 at a constant speed, the workpiece will be subjected to continuous extrusion force from the horizontal and vertical directions under the action of the first straightening wheel 34 and the second straightening wheel 35. Its curved parts will be gradually straightened, thereby straightening the workpiece. S4. When the second transmission wheel 29 rotates, it drives the turntable 51 to rotate via the connecting shaft 57. The turntable 51 drives the movable frame 52 to rotate, and the movable frame 52 moves up and down on the outside of the fixed rod 53. At the same time, the fixed rod 53 drives the movable seat 54 to move back and forth. The movable seat 54 drives the slide 55 to move on one side of the slide rail 56. Under the action of the slide 55 and the slide rail 56, the stability of the movable seat 54 during movement is enhanced. When the turntable 51 drives the fixed column 59 to move downward via the movable frame 52, the fixed column 59 drives the reset baffle 510 to press down. At this time, the reset spring... When 511 is compressed, the reset baffle 510 will drive the cutting blade 513 to cut the workpiece via the movable rod 512. After the cutting blade 513 completes the cutting, the turntable 51 continues to rotate, driving the movable frame 52 to move upward. At this time, the fixed post 59 separates from the reset baffle 510. Under the elastic force of the reset spring 511, it will push the movable rod 512 to reset upward, causing the cutting blade 513 to disengage from the blade groove 514 and return to the initial standby position. As the turntable 51 continues to rotate, the cutting blade 513 reciprocates, cooperating with the constant speed feeding of the workpiece, thereby achieving continuous and precise cutting at a fixed distance.

10. A straightening method for a straightening device used in the processing of communication connectors, comprising the following steps, characterized in that: S1. First, the workpiece is passed through the top of the first straightening wheel (34) and the first conveying roller (22) in sequence, and then through the inside of the guide groove (515). At this time, the handwheel (33) is turned. The handwheel (33) will drive the threaded column (32) to rotate inside the fixed frame (31). The threaded column (32) will drive the movable seat (36) to rise and fall. At the same time, the movable seat (36) will move outside the slide bar (37). Under the action of the slide bar (37), the stability of the movable seat (36) during movement is enhanced. After the movable seat (36) moves, it will drive the second straightening wheel (35) to move, so as to facilitate the adjustment of the gap between the second straightening wheel (35) and the first straightening wheel (34), thereby adapting to slender workpieces of different diameters. S2. Start the electric push rod (23) to drive the movable frame (27) to rise and fall. The movable frame (27) will drive the guide rod (28) to move inside the fixed frame (21). Under the action of the guide rod (28), the stability of the movable frame (27) during movement is enhanced. After the movable frame (27) moves, it will drive the second conveying roller (25) to move, so as to facilitate the adjustment of the gap between the second conveying roller (25) and the first conveying roller (22), ensuring that the first conveying roller (22) and the second conveying roller (25) are in close contact with the workpiece surface, so as not to slip or damage the workpiece, thus facilitating stable conveying of the workpiece. S3. Start the drive motor (24) to make the first conveying roller (22) rotate at the bottom of the fixed frame (21). The first conveying roller (22) will drive the second transmission roller (29) to rotate through the first transmission wheel (26) and the transmission belt (210). At the same time, the workpiece at the top of the roller will move forward due to friction. At this time, the friction of the workpiece will drive the second conveying roller (25) to rotate synchronously. Under the action of the second conveying roller (25) and the first conveying roller (22), the workpiece is clamped and transported synchronously to avoid the workpiece from shifting during transport. The transported workpiece will drive the first straightening wheel (34) and the second straightening wheel (35) to rotate. When the workpiece passes through the interlaced first straightening wheel (34) and the second straightening wheel (35) at a constant speed, the workpiece will be subjected to continuous extrusion force from the horizontal and vertical directions under the action of the first straightening wheel (34) and the second straightening wheel (35). Its curved parts will be gradually straightened, thereby straightening the workpiece. S4. When the second transmission wheel (29) rotates, it drives the turntable (51) to rotate through the connecting shaft (57). The turntable (51) drives the movable frame (52) to rotate. The movable frame (52) moves up and down on the outside of the fixed rod (53), while the fixed rod (53) drives the movable seat (54) to move back and forth. The movable seat (54) drives the slide (55) to move on one side of the slide rail (56). Under the action of the slide (55) and the slide rail (56), the stability of the movable seat (54) during movement is enhanced. When the turntable (51) drives the fixed column (59) to move downward through the movable frame (52), the fixed column (59) drives the reset baffle (510) to press down. When the reset spring (511) is compressed, the reset baffle (510) will drive the cutting blade (513) to cut the workpiece through the movable rod (512). After the cutting blade (513) completes the cutting, the turntable (51) continues to rotate and drives the movable frame (52) to move upward. At this time, the fixed column (59) separates from the reset baffle (510). Under the elastic force of the reset spring (511), the movable rod (512) will be pushed upward to reset, so that the cutting blade (513) will disengage from the blade groove (514) and return to the initial standby position. As the turntable (51) continues to rotate, the cutting blade (513) will reciprocate. With the constant speed feeding of the workpiece, continuous and precise cutting at a fixed distance can be achieved.
