Description

Technical Field

[0001] The present invention relates to the field of connector interface processing, and more particularly to a flexible cable connector interface processing device. Background Art

[0002] Cables are conductors that are frequently used in our daily lives. With the continuous development of the social economy, the use of cables is also growing rapidly, and the quality requirements for cables are also constantly improving. For example, cables used in the chemical, metallurgical, electric power, steel and other industries have high requirements for high temperature resistance, anti-interference ability, tensile strength and service life. Cable connector terminals are a metal component used to terminate cable conductors. They are generally sheet-shaped, needle-shaped or cylindrical in structure. They are fixed to the end of the wire through mechanical connection (such as crimping) or welding, and then cooperate with other terminals or sockets to achieve circuit conduction or signal transmission between devices.

[0003] When processing cable connector terminals, existing technology often uses terminal bending equipment to bend straight terminals into 90 degrees to meet connection requirements; however, during the one-time bending process, high requirements are often placed on the material of the terminals, resulting in cracks in terminals made of general materials during bending, thereby affecting the quality of the processed terminals.

[0080] In an embodiment of the present invention, a feeding portion 2 is provided to transport the connector terminals 8 to be processed one by one to the bending portion 3, and the connector terminals 8 are bent. Since the terminals are moved forward one by one, the accuracy of the bending is guaranteed, and precise cutting can be achieved when the connector terminals 8 to be processed are cut into finished connector terminals 8; a three-level bending assembly is provided, so that the connector terminals 8 to be processed are first bent at a 45-degree angle, and then bent at a 90-degree angle under the condition of 45-degree bending, thereby avoiding a one-time bending of 90 degrees, causing the terminals to crack or deform, thereby affecting the terminal quality; at the same time, in order to ensure the efficiency of the bending, the bending operation time is short, and the terminals have not yet adapted to the new angle at this time, thereby generating rebound, and an interference bending assembly is provided, which performs inward extrusion at a certain angle on the basis of bending at 90 degrees, thereby ensuring that the connector terminals 8 produced in high-speed production can be bent 90 degrees.

[0081] Among them, the connector terminals 8 are connected one by one by metal plates. In a narrow sense, the connecting terminals excluding the metal plates can be called connector terminals 8; while in real life, the connector terminal 8 is a whole composed of several terminals and metal plates connected together.

[0082] like Figures 3 and 4 As shown, the feeding part 2 includes: a first support plate 201, which is arranged at the top of the support frame 101; a first feed trough 202, which is arranged at the top of the first support plate 201 to place the connector terminal 8, and is connected with the second feed trough 401 to smoothly transport the connector terminal 8 to the bending part 3; an intermittent feeding component, which is arranged on the first support plate 201 to drive the step-by-step feeding of the connector terminal 8; a limiting plate 211, which is arranged on the first feed trough 202 to limit the connector terminal 8; a driving through groove 212, which is opened on the limiting plate 211 and cooperates with the intermittent feeding component.

[0083] like Figures 3 and 4 As shown, the intermittent feeding assembly includes: a first supporting side plate 203, which is arranged on the supporting frame 101; a second supporting side plate 204, which is arranged on the first supporting plate 201; a first motor 209, which is arranged on the second supporting side plate 204 in a direction away from the first feeding trough 202, and the output end of the first motor 209 is passed through the first supporting side plate 203; a first gear 207, which is connected to the output end of the first motor 209; a second gear 208, which is meshed and connected with the first gear 207; a first connecting shaft 210, which is passed through the first supporting side plate 203 and the second supporting side plate 204, and one end is connected to the second gear 208; a rotating disk 205, which is connected to the other end of the first connecting shaft 210; a plurality of groups of needle rollers 206, which are evenly distributed on the circumference of the rotating disk 205, and pass through the driving slot 212 to cooperate with the connector terminal 8 for drive.

[0084] In an embodiment of the present invention, when feeding, the connector terminal 8 to be bent is first placed in the first feeding trough 202 to ensure that the needle roller 206 can touch the connector terminal 8 when it rotates; then the first motor 209 is started to drive the first gear 207 to rotate, and the first gear 207 drives the second gear 208 to rotate, and the second gear 208 drives the rotating disk 205 to rotate through the first connecting shaft 210, thereby driving the needle roller 206 at the outer end of the rotating disk 205 to rotate; since there is a gap between the two terminals, the needle roller 206 will rotate into the gap between the two terminals, rotate to drive the terminal on one side to move forward, and continue to rotate, the needle roller 206 will fall off the terminal and move upward, at this time, the movement stops until the next needle roller 206 rotates into the gap between the two terminals, driving one terminal to move forward; in this way, step-by-step feeding is formed, so that when cutting the connector terminal 8 to be processed into a finished connector terminal 8, precise cutting can be achieved; and when bending the terminal, precise bending can be achieved.

[0085] like Figures 5 to 9 As shown, the preliminary bending assembly includes: a limiting bevel block 403, which is arranged in the first bending groove 402 and is located at one end of the second feed trough 401 away from the first feed trough 202; a first inclined bending block 501, which is arranged at the bottom end of the stamping block 302 and is directly above the limiting bevel block 403.

[0086] like Figures 5 to 9 As shown, the right-angle bending assembly includes: a right-angle bending block 502, which is arranged at the bottom end of the stamping block 302 and is directly above the first bending groove 402, and the end of the right-angle bending block 502 close to the bending part is designed to be a 90-degree arc, so as to avoid irregular deformation of the bending part of the connector terminal 8 and affect the quality of the connector terminal 8.

[0087] like Figures 5 to 9 As shown, the interference bending assembly includes: a second bending groove 404, which is opened on the processing base 301 and connected to the first bending groove 402; a first sliding block 405, which slides in the second bending groove 404, and the top of the first sliding block 405 is designed to be inclined; a spring 406, one end of which is connected to the second bending groove 404, and the other end is connected to the first sliding block 405; an interference bending block 503, which is arranged at the bottom end of the stamping block 302, directly above the first sliding block 405, and the bottom end is designed to be inclined, which is connected to the inclined surface of the first sliding block 405 to drive the first sliding block 405 to move.

[0088] like Figures 10 and 11As shown, the driving part includes: a second support plate 701, connected to the bottom end of the limiting sliding rod 304; a second connecting shaft 702, rotatably connected to the inner wall of the support frame 101; a rotating cam 703, sleeved on the second connecting shaft 702, and located directly below the second support plate 701; a fourth gear 705, sleeved on the second connecting shaft 702; a third gear 704, meshingly connected with the fourth gear 705; a second motor 706, arranged on the inner wall of the support frame 101, and the output end is connected to the third gear 704.

[0089] In the embodiment of the present invention, in order to drive the stamping block 302 to move downward, it is necessary to start the second motor 706 to drive the third gear 704 to rotate, and the third gear 704 drives the fourth gear 705 to rotate, thereby driving the rotating cam 703 to rotate through the second connecting shaft 702, and the rotating cam 703 rotates to drive the second support plate 701 to move up and down, thereby driving the two limiting sliding rods 304 to move up and down, and the limiting sliding rods 304 drive the connecting top plate 303 to move up and down, thereby driving the stamping part to move up and down; wherein, the shape of the designed cam is that when the cam rotates one circle, it will drive the second support plate 701 to move upward, then remain stationary for a short time, then move downward, and finally remain stationary for a short time; the four states are cycled; so that when bending, there will be a certain period of time to maintain the state of the terminal.

[0090] When the connector terminal 8 to be bent moves to the bending portion 3, the driving portion drives the punching block 302 to move downward.

[0091] The first inclined bending block 501 is thereby driven to move downward to cooperate with the limiting inclined block 403, thereby squeezing the terminal sandwiched between the first inclined bending block 501 and the limiting inclined block 403 into a 45-degree angle, and the angle is at the position where the limiting inclined block 403 contacts the connector terminal 8; the terminal is further moved forward to be squeezed into a 45-degree angle, and the punching block 302 is similarly driven downward by the driving portion, and the punching block 302 drives the right-angle bending block 502 downward, thereby bending the 45-degree connector terminal 8 into a 90-degree angle; wherein, the end of the right-angle bending block 502 close to the bend is designed to be a 90-degree arc, thereby protecting the shape of the bend of the connector terminal 8 and improving the processing quality;

[0092] Continue to move forward and extrude the terminal into a 90-degree shape. Similarly, the driving unit drives the stamping block 302 to move downward. The stamping block 302 drives the interference bending block 503 to move downward, thereby pushing the first sliding block 405 to move along the second bending groove 404 toward the end close to the connector terminal 8. When the first sliding block 405 moves, it drives the spring 406 to stretch, thereby squeezing the 90-degree terminal at a certain angle, thereby avoiding the bending time being too short, causing the connector terminal 8 to rebound and affecting the bending quality. At the same time, after the bending is completed, the spring 406 rebounds, causing the first sliding block 405 to return to its initial position, thereby facilitating the next stamping movement.

[0093] Among them, when bending, the bending areas of the first inclined bending block 501, the right-angle bending block 502 and the interference bending block 503 just cover the three connector terminals 8; thus, in the process of feeding the terminals one by one, each terminal will undergo three bending operations of each bending block, thereby further ensuring the bending quality of the connector terminal 8.

[0094] like Figures 8 and 9 As shown, the cutting part includes: a sliding square rod 604, which is arranged at the bottom end of the punching block 302; a limiting plate 606, which is connected to the bottom end of the sliding square rod 604; a cutting knife 607, which is arranged at the bottom end of the limiting plate 606 to facilitate installation and disassembly, and as the punching block 302 moves downward to cut the connector terminal 8 to be processed into a separate whole; a cutting groove 601, which is opened on the processing base 301 to place the cutting knife 607; a driving component, which is arranged at the bottom end of the punching block 302 to drive the sliding square rod 604 to slide.

[0095] like Figures 8 and 9 As shown, the driving assembly includes: a slide rail 603, which is arranged at the bottom end of the punching block 302, and the sliding square rod 604 moves in the slide rail 603; a fixed plate 602, which is arranged at the bottom end of the punching block 302; an electric telescopic rod 605, which is arranged on the fixed plate 602, and the output end is connected to the sliding square rod 604 to drive the sliding square rod 604 to move on the slide rail 603.

[0096] like Figures 1 to 11 As shown, an electric control module is provided. When the connector terminals 8 are cut, the number of the connector terminals 8 entering is determined according to the number of revolutions of the first motor 209. A connector as a whole is composed of several terminals. When the specified number of terminals is reached, that is, the first motor 209 rotates the specified number of revolutions, and sends an electric signal to make the electric telescopic rod 605 achieve a cyclic movement of extension, stop, and shortening, thereby driving the cutting knife 607 to cut the connector terminal 8 to be processed at the specified position to form the finished connector terminal 8.

[0097] In an embodiment of the present invention, the metal plate of the connecting terminal is cut off so that the metal plate and several terminals together form the finished product of the connector terminal 8. Therefore, when it is in the cut-off position, the electric telescopic rod 605 is started to drive the sliding square rod 604 to move along the slide rail 603, so that the sliding square rod 604 drives the cutting knife 607 to move through the limit plate 606, so that the cutting knife 607 moves to the top of the metal plate of the connector terminal 8; at this time, the stamping part moves downward, so that the cutting knife 607 cuts the metal plate, thereby completing the overall processing of the connector terminal 8.

[0098] The number of revolutions of the first motor 209 determines the number of connector terminals 8 that are moved forward. After a completed connector terminal 8 is reached, an electrical signal is released, causing the electric telescopic rod 605 to extend, thereby driving the cutting blade 607 to reach directly above the metal sheet. At the same time, by controlling the operating speeds of the first motor 209 and the second motor 706, the stamping part moves upward during feeding and moves downward to bend during feeding pauses, thereby preventing the equipment from being stuck during feeding and bending. At the same time, the extension pause of the electric telescopic rod 605 also occurs when the stamping part moves downward. When the stamping part moves upward, the electric telescopic rod 605 retracts, thereby driving the cutting blade 607 to move above the cutting groove 601. At this time, even if the stamping part moves downward, the cutting blade 607 will only move into the cutting groove 601 without damaging the equipment.

[0099] Working principle: When feeding, first place the connector terminal 8 to be bent in the first feeding slot 202 to ensure that the needle roller 206 can touch the connector terminal 8 when it rotates; then start the first motor 209 to drive the first gear 207 to rotate, the first gear 207 drives the second gear 208 to rotate, and the second gear 208 drives the rotating disk 205 to rotate through the first connecting shaft 210, thereby driving the needle roller 206 at the outer end of the rotating disk 205 to rotate; since there is a gap between the two terminals, the needle roller 206 will rotate into the gap between the two terminals, and rotate to drive the terminal on one side to move forward, and if it continues to rotate, the needle roller 206 will fall off the terminal and move upward, at this time, the movement stops until the next needle roller 206 rotates into the gap between the two terminals, driving one terminal to move forward; in this way, step-by-step feeding is formed;

[0100] When the connector terminal 8 to be bent moves to the bending portion 3, the second motor 706 is started to drive the third gear 704 to rotate, and the third gear 704 drives the fourth gear 705 to rotate, thereby driving the rotating cam 703 to rotate through the second connecting shaft 702, and the rotating cam 703 rotates to drive the second support plate 701 to move up and down, thereby driving the two limiting sliding rods 304 to move downward, and the limiting sliding rods 304 drive the connecting top plate 303 to move up and down, thereby driving the stamping part to move up and down; thereby driving the first inclined bending block 501 to move downward to cooperate with the limiting inclined block 403, thereby The terminal sandwiched between the first inclined bending block 501 and the limiting inclined block 403 is extruded into a 45-degree angle, and the angle is located at the position where the limiting inclined block 403 contacts the connector terminal 8; the terminal is continued to move forward to be extruded into a 45-degree angle, and the driving unit drives the punching block 302 to move downward, and the punching block 302 drives the right-angle bending block 502 to move downward, thereby bending the 45-degree connector terminal 8 into a 90-degree angle; wherein, the end of the right-angle bending block 502 close to the bend is designed to be a 90-degree arc, thereby protecting the shape of the bend of the connector terminal 8 and improving the processing quality;

[0101] Continuing to move forward, the terminal is extruded into a 90-degree angle. Similarly, the driving unit drives the punching block 302 to move downward, and the punching block 302 drives the interference bending block 503 to move downward, thereby pushing the first sliding block 405 to move along the second bending groove 404 toward the end close to the connector terminal 8. When the first sliding block 405 moves, it drives the spring 406 to stretch, thereby extruding the 90-degree terminal at a certain angle, thereby avoiding the bending time being too short, which causes the connector terminal 8 to rebound and affect the bending quality. At the same time, after the bending is completed, the spring 406 rebounds, causing the first sliding block 405 to return to its initial position, thereby facilitating the next stamping movement.

[0102] During the bending process, the number of revolutions of the first motor 209 is used to determine the number of forward movements of the connector terminals 8. After reaching a completed connector terminal 8, an electrical signal is released to extend the electric telescopic rod 605, thereby driving the cutting knife 607 to reach directly above the metal sheet. At the same time, by controlling the working speeds of the first motor 209 and the second motor 706, the stamping part moves upward when the feeding is moving; during the feeding interval, the stamping part moves downward to bend, thereby avoiding feeding during bending and causing the equipment to jam. At the same time, the extension interval of the electric telescopic rod 605 is also when the stamping part moves downward, and when the stamping part moves upward, the electric telescopic rod 605 contracts. Finally, the bending and processing of the connector terminal 8 is completed.

[0103] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
