Description

Technical Field

[0001] The utility model relates to the technical field of wire processing equipment, and particularly to an ultra-short wire processing equipment. Background Art

[0002] With the development of technology, electronic products are becoming more and more miniaturized, with higher and higher requirements for the precision of components, more and more precise processing of components, higher and higher requirements for processes, shorter and shorter processing time for components, and better and better quality of components. These are all the development trends in the electronics industry. For the processing of components, it is necessary to require higher and higher precision of the process, shorter and shorter processing length of the components, and better and better quality of the components.

[0003] Ultra-short two-end processed wires are wires processed at both ends, usually used to connect electronic components or circuit boards. The length of this kind of wire is very short, usually only a few centimeters to more than a dozen centimeters, and is suitable for occasions with narrow space or requiring a compact layout. They can be connected to the circuit board or other components by means of welding, crimping or plugging. This kind of wire is usually used in fields such as electronic equipment, communication equipment and medical equipment.

[0004] For ultra-short two-end processed wires, the processing length must be controlled within a certain precision range according to the process requirements. Otherwise, the cumulative errors of each component during installation will cause different lengths. If the processing length of the ultra-short two-end processed wire is too long, it will cause deformation of the inserted PCB board. Currently, ultra-short two-end processed wires are generally made manually, not only the processing precision is difficult to guarantee, but also the processing efficiency is low.

[0035] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present utility model.

[0036] Referring to Figures 1 to 13 As shown, the present utility model provides a ultra - short - wire processing device, including: a wire pre - pay - off mechanism 1 for automatically feeding the wire; a pay - off and cutting mechanism 2 for receiving the wire paid off by the wire pre - pay - off mechanism 1, automatically sending out and cutting the wire of the required length, and stripping the first end of the cut wire; a first - terminal loading and crimping mechanism 3 for loading the terminal, receiving the wire after stripping, and crimping the terminal at the first - end crimping position of the wire; a wire - transferring mechanism 4 for transferring the wire with the terminal crimped at the first end to the second - end crimping position; an automatic wire - stripping mechanism 5 for stripping the second end of the wire at the second - end crimping position; a second - terminal loading and crimping mechanism 6 for loading the terminal, receiving the wire after being stripped by the automatic wire - stripping mechanism 5, and crimping the terminal at the second end of the wire; a heat - shrinkable tube cutting and threading mechanism 7 for cutting the heat - shrinkable tube and sleeving the cut heat - shrinkable tube on the wire after the terminal crimping is completed; a heat - shrinking mechanism 8 for heat - shrinking the heat - shrinkable tube sleeved on the wire; a finished - product collecting mechanism 9 for handling the wire after heat - shrinking is completed.

[0037] In one embodiment, the wire pre - pay - out mechanism 1 further includes a pay - out frame 11, a wire wheel 12, and a pulley - group force - saving mechanism 13. The wire wheel 12 and the pulley - group force - saving mechanism 13 are both installed on the pay - out frame 11. The pulley - group force - saving mechanism 13 includes at least one fixed pulley and one movable pulley. The fixed pulley is fixed on the pay - out frame 11, and the movable pulley is movably installed on the pay - out frame 11. The motor drives the wire wheel 12 to rotate for wire pay - out. The wire enters the wire pay - out and cutting mechanism 2 through the guidance of the pulley - group force - saving mechanism 13. The combination of the fixed pulley and the movable pulley of the pulley - group force - saving mechanism 13 realizes the effect of force - saving wire feeding, and at the same time disperses the acting force of the wire on the wire pre - pay - out mechanism 1 during the wire - feeding process, avoiding damage to the wire pre - pay - out mechanism 1 or the wire.

[0038] In the above - mentioned technical solution, the wire pre - pay - out mechanism 1 is used for automatically feeding the wire. By setting the pulley - group force - saving mechanism 13 in the wire pre - pay - out mechanism 1, it is possible to avoid the situation that the acting force between the wire and the wire pre - pay - out mechanism 1 is too concentrated during the wire - feeding process, resulting in damage to the wire pre - pay - out mechanism 1 or the wire. The wire pay - out and cutting mechanism 2 is used to receive the wire released by the wire pre - pay - out mechanism 1, cut the wire to the required length and automatically send it out, and strip the first end of the cut wire. The first - terminal feeding and crimping mechanism 3 is used for terminal feeding, receiving the wire after stripping, and crimping the first end of the wire at the first - end crimping position. The wire is transported to the second - end crimping position by the wire - transfer mechanism 4. The automatic stripping mechanism 5 strips the second end of the wire at the second - end crimping position. The second - terminal feeding and crimping mechanism 6 is used for terminal feeding, receiving the wire stripped by the automatic stripping mechanism 5, and crimping the terminal at the second end of the wire. The heat - shrinkable tube cutting and threading mechanism 7 can cut the heat - shrinkable tube and sleave the cut heat - shrinkable tube on the wire after terminal crimping. The heat - shrink mechanism 8 shrinks the heat - shrinkable tube sleeved on the wire. The finished - product collecting mechanism 9 is used for handling the wire after heat - shrinking. Through the cooperation of mechanisms such as the wire pre - pay - out mechanism 1 and the wire pay - out and cutting mechanism 2, the length of the ultra - short wire of the ultra - short - wire processing equipment is accurately cut, and rapid processing of both ends of the wire is realized. Compared with general manual processing, the processing accuracy and processing efficiency of both ends of the ultra - short wire are improved. In one embodiment, the wire - transfer mechanism 4 includes: a frame 41; a first clamping part 42, movably arranged on the frame 41 and capable of clamping the second end of the wire with the terminal crimped at the first end; a second clamping part 43, movably arranged on the frame 41, capable of clamping the first end of the wire located on the first clamping part 42 and transporting the wire to the second - end crimping position.

[0039] In the above technical solution, the first clamping part 42 and the second clamping part 43 are both movably arranged on the frame 41. The first clamping part 42 clamps the second end of the wire with the terminal crimped at the first end, and moves together with the second clamping part 43 to the wire handover position, so that the second clamping part 43 can clamp the first end of the wire located on the first clamping part 42. Then, the first clamping part 42 releases the wire to realize the handover of the wire, and the second clamping part 43 clamps the first end of the wire and transports it to the second end crimping position. Since the position clamped by the second clamping part 43 is the first end of the wire with the terminal crimped, the unpeeled second end of the wire is exposed, which facilitates the transportation of the unpeeled second end of the wire to the peeling position for peeling treatment, improving the continuity of the process and the transportation efficiency.

[0040] In one embodiment, a transfer guide rail 44 is arranged on the frame 41. The second clamping part 43 is arranged on the transfer guide rail 44 and can move along the guidance of the transfer guide rail 44. The first clamping part 42 can move in a direction close to or away from the transfer guide rail 44.

[0041] In the above technical solution, the second clamping part 43 moves along the guidance of the transfer guide rail 44 to realize the movement of the second clamping part 43 between the wire handover position and the first end crimping position; the first clamping part 42 can move in a direction close to or away from the transfer guide rail 44, so that the first clamping part 42 moves in a direction close to or away from the transfer guide rail 44 and can reach a position aligned with the second clamping part 43, facilitating the second clamping part 43 to move to the wire handover position to accurately clamp the wire and realize the handover of the wire.

[0042] In one embodiment, the first clamping part 42 includes: a telescopic cylinder 421 that can telescopically move in a direction close to or away from the transfer guide rail 44; a first clamping cylinder 422 arranged at the telescopic end of the telescopic cylinder 421; and a first transfer jaw 423 arranged at the end of the first clamping cylinder 422 and clamping or releasing under the action of the first clamping cylinder 422.

[0043] In the above technical solution, the telescopic cylinder 421 provides power for the first clamping part 42 to enable the first clamping part 42 to telescopically move in a direction close to or away from the transfer guide rail 44; the first clamping cylinder 422 provides power for the clamping and releasing actions of the first transfer jaw 423; the first transfer jaw 423 is arranged at the end of the first clamping cylinder 422 and clamps or releases the second end of the wire under the action of the first clamping cylinder 422.

[0044] In one embodiment, the first clamping cylinder 422 is slidably arranged on the telescopic cylinder 421 in the up and down directions, and the first transport clamp 423 is an L-shaped structure. The first transport clamp 423 includes a first side portion and a second side portion at an angle. The first side portion is connected to the first clamping cylinder 422, and a clamping space is formed between the two oppositely arranged second side portions.

[0045] In the above technical solution, the first clamping cylinder 422 is slidably arranged on the telescopic cylinder 421 in the up and down directions, and cooperates with the telescopic movement of the telescopic cylinder 421 in the direction of approaching or moving away from the transfer guide rail 44, so that the first transfer clamping claw 423 arranged on the first clamping cylinder 422 can move freely in the plane where the telescopic cylinder 421 and the first clamping cylinder 422 are located, ensuring that the wire clamped by the first transfer clamping claw 423 is aligned with the second clamping part 43, so that the second clamping part 43 can accurately clamp the wire, thereby improving the accuracy of the second clamping part 43 in clamping the wire and the transfer efficiency.

[0046] In one embodiment, the second clamping part 43 includes: a transfer sliding seat 431, which is slidably set on the transfer guide rail 44, and a cantilever structure is set on the transfer sliding seat 431; a second clamping cylinder 432, which is set on the cantilever structure; a second transfer clamping jaw 433, which is set at the end of the second clamping cylinder 432, and clamps or releases under the action of the second clamping cylinder 432; when the second transfer clamping jaw 433 slides toward the wire, the first transfer clamping jaw 423 moves to the sliding path of the second transfer clamping jaw 433, and when the second transfer clamping jaw 433 slides to the transfer position, the second transfer clamping jaw 433 clamps the first end of the wire, the first transfer clamping jaw 423 is released, and the second transfer clamping jaw 433 transfers the wire to the second end crimping position through the transfer robot.

[0047] In the above technical solution, a cantilever structure is provided on the transfer sliding seat 431 for carrying the second clamping cylinder 432. The transfer sliding seat 431 is slidably set on the transfer guide rail 44, so that the second clamping cylinder 432 and the second transfer clamping claw 433 carried by the transfer sliding seat 431 can slide along the transfer guide rail 44 together with the transfer sliding seat 431, thereby realizing the movement of the second transfer clamping claw 433 between the wire junction position and the first end crimping position; the second transfer clamping claw 433 is set at the end of the second clamping cylinder 432, and realizes the clamping or loosening action under the action of the second clamping cylinder 432.

[0048] In one embodiment, the first terminal feeding and crimping mechanism 3 includes: a feeding mechanism 31 for performing vibration feeding of the terminal; a terminal clamping mechanism 32 for clamping the terminal from the feeding mechanism 31 to the first end crimping position; and a terminal crimping device 33 for crimping the terminal to the first end of the wire.

[0049] In the above technical solution, the feeding mechanism 31 realizes the vibrating feeding of terminals through the vibration of the tray. The terminal clamping mechanism 32 clamps the terminal material out of the vibrating feeding tray and transfers it to the first end crimping position. At the first end crimping position, the terminal is crimped to the first end of the wire by the terminal crimping device 33.

[0050] In one embodiment, the terminal clamping mechanism 32 includes: a lifting device 321, which is liftably arranged at the feeding mechanism 31; a transfer device 322, which is arranged at the lifting end of the lifting device 321 and can be transferred relative to the lifting device 321; an upper clamping jaw 323, which is arranged on the transfer device 322 and moves with the transfer device 322 to clamp the terminals on the feeding mechanism 31; a conveying device 324, which is arranged below the upper clamping jaw 323; and a lower clamping jaw 325, which is arranged on the conveying device 324, receives the terminals clamped by the upper clamping jaw 323, and clamps the terminals to the first end crimping position under the conveying action of the conveying device 324.

[0051] In the above technical solution, the lifting device 321 is liftably arranged at the feeding mechanism 31 and is used to drive the upper clamping jaw 323 to lift in the vertical direction; the transfer device 322 is arranged at the lifting end of the lifting device 321 and can be transferred relative to the lifting device 321. The upper clamping jaw 323 is arranged on the transfer device 322, so that the upper clamping jaw 323 can be transferred along with the transfer device 322; through the cooperation of the lifting device 321 and the transfer device 322, the terminal clamping mechanism 32 can complete the lifting and transfer actions, thereby driving the upper clamping jaw 323 to move between the transfer position where the terminals are handed over to the lower clamping jaw 325 and the feeding mechanism 31 to complete the clamping and feeding of the terminals, and will not interfere with other structures; the conveying device 324 drives the lower clamping jaw 325 to move between the terminal transfer position and the first end crimping position; the specific working process of the terminal clamping mechanism 32 is as follows: through the cooperation of the lifting device 321 and the transfer device 322, the upper clamping jaw 323 reaches the feeding mechanism 31 to clamp the terminals, and then the upper clamping jaw 323 clamps the terminals and moves to the transfer position where the terminals are handed over to the lower clamping jaw 325. The conveying device 324 drives the lower clamping jaw 325 to move to the terminal transfer position to clamp the terminals. After the upper clamping jaw 323 releases the terminals, the handover of the terminals is completed. The lower clamping jaw 325 clamps the terminals to the first end crimping position under the conveying action of the conveying device 324.

[0052] In one embodiment, the transfer device 322 is a rotating device. The upper clamping jaw 323 is arranged on the rotating device. After the upper clamping jaw 323 is lifted to the material taking height by the lifting device 321, the rotating device drives the upper clamping jaw 323 to rotate to the feeding mechanism 31 to clamp the terminals, which can conveniently, quickly and accurately clamp the terminals, and at the same time avoid interference between the terminal clamping mechanism 32 and the feeding mechanism 31 during the process of clamping the terminals.

[0053] In one embodiment, the transfer device 322 includes a first horizontal displacement device and a second horizontal displacement device. The first horizontal displacement device controls the movement of the upper gripper in a direction close to or away from the lower gripper, and the second horizontal displacement device controls the movement of the upper gripper in a direction close to or away from the feeding mechanism 31. After the lifting device 321 lifts the upper gripper 323 to the picking height, the two horizontal displacement devices cooperate to move the upper gripper 323 to the feeding mechanism 31 to pick up the terminals, which can pick up the terminals conveniently, quickly and accurately, and at the same time avoid interference between the terminal picking mechanism 32 and the feeding mechanism 31 during the process of picking up the terminals.

[0054] In one embodiment, the wire feeding and cutting mechanism 2 includes: a wire feeding mechanism 21, which is arranged at the wire feeding end of the wire pre-feeding mechanism 1 and feeds a preset length of wire; a cutting mechanism 22, which is arranged on the wire feeding path of the wire feeding mechanism 21, cuts the wire of the required length, and strips the first end of the wire.

[0055] In the above technical solution, the wire feeding mechanism 21 positions the wire entering the device from the wire pre-feeding mechanism 1, accurately feeds the wire into the cutting mechanism 22, and controls the wire feeding length to realize feeding a preset length of wire; the cutting mechanism 22 is arranged on the wire feeding path of the wire feeding mechanism 21, cuts the wire of the required length, and strips the first end of the wire.

[0056] In one embodiment, the wire feeding and cutting mechanism 2 further includes a linear guide rail 23. The wire feeding mechanism 21 is arranged on the linear guide rail 23 and can move horizontally along the linear guide rail 23. Since the position where the wire enters the wire feeding and cutting mechanism 2 from the wire pre-feeding mechanism 1 will change, by setting the linear guide rail 23, the wire feeding and cutting mechanism 2 moves horizontally as the wire entering position changes, reducing the influence brought by wire deviation, improving the accuracy of the wire entering the cutting mechanism 22, and thus ensuring more accurate wire cutting length.

[0057] In one embodiment, the wire feeding mechanism 21 includes wire feeding guide wheels 211 and a wire feeding servo motor 212. There are two groups of wire feeding guide wheels 211. The first group of wire feeding guide wheels 211 includes a plurality of wire feeding guide wheels 211 alternately arranged on both sides of the wire along the wire feeding direction. The second group of wire feeding guide wheels 211 includes a plurality of wire feeding guide wheels 211 alternately arranged on both sides of the wire along the wire feeding direction. The central axis of the first group of wire feeding guide wheels 211 is perpendicular to the central axis of the second group of wire feeding guide wheels 211. The driving end of the wire feeding servo motor 212 is drivingly connected to one of the wire feeding guide wheels 211.

[0058] In the above technical solution, the wire feeding guide wheel 211 is used to drive the wire to move for wire feeding. The wire feeding guide wheel 211 includes a first group of wire feeding guide wheels 211 and a second group of wire feeding guide wheels 211. The central axis of the first group of wire feeding guide wheels 211 is perpendicular to the central axis of the second group of wire feeding guide wheels 211. One group limits the wire in the horizontal direction, and the other group limits the wire in the vertical direction. Through the cooperation of the two groups of wire feeding guide wheels 211 that are perpendicular to each other, the purpose of accurately feeding the wire entering the equipment from the wire pre-feeding mechanism 1 into the cutting mechanism 22 is achieved, avoiding the problem of reduced precision in the length of wire cutting caused by wire bending and deviation. The wire feeding servo motor 212 provides power for the rotation of the wire feeding guide wheel 211. At the same time, through the precise control of the number of rotations and the rotation angle of the wire feeding guide wheel 211 by the wire feeding servo motor 212, the effect of accurately feeding the required wire length by the wire feeding mechanism 21 is achieved, improving the control precision of the wire length. In one embodiment, the automatic peeling mechanism 5 includes a cutting mechanism identical to that of the wire feeding and cutting mechanism 2. The second end of the wire from the wire transfer mechanism 4 is placed in the peeling position by the clamping jaws. The outer skin of the second end of the wire is removed by the cutting mechanism of the automatic peeling mechanism 5, and then the wire with the second end already peeled is transported to the second terminal feeding and crimping mechanism 6 for the next process.

[0059] In one embodiment, the cutting mechanism is a V-shaped knife structure, which has a good cutting and peeling effect.

[0060] In one embodiment, the second terminal feeding and crimping mechanism 6 includes a second terminal feeding mechanism 61, a second terminal cutting mechanism, and a second terminal crimping device 62.

The second terminal crimping device 62 is the same as the terminal crimping device 33 of the first terminal feeding and crimping mechanism 3. When the second terminal feeding and crimping mechanism 6 works, the second end of the wire is placed in the crimping position of the second terminal crimping device 62 by the clamping jaws. The second terminal feeding mechanism 61 feeds the chain belt terminals at the second end into the second terminal cutting mechanism, and the cutting knife of the second terminal cutting mechanism cuts the chain belt terminals. The cut chain belt terminals are transported to the crimping position of the second terminal crimping device 62 through the conveying track 612 and are aligned with the second end of the wire at the crimping position, and then the second terminal is crimped and fixed on the second end of the wire by the second terminal crimping device 62.

[0061] In one embodiment, the heat shrink tube cutting and threading mechanism 7 includes a heat shrink tube loading mechanism 71, a heat shrink tube cutting mechanism 72, and a heat shrink tube threading mechanism 73. The heat shrink tube loading mechanism 71 transports the heat shrink tube to the heat shrink tube cutting mechanism 72, and the heat shrink tube cutting mechanism 72 cuts the heat shrink tube to a preset length. The heat shrink tube cutting mechanism 72 includes two conveying wheels, and a conveying space is formed between the two conveying wheels. The heat shrink tube is clamped in the conveying space and conveyed by the conveying wheels. In this embodiment, one of the conveying wheels is driven to rotate by a servo motor, and the servo motor calculates the cutting length of the heat shrink tube. When the heat shrink tube extends a preset length, the heat shrink tube is cut by a cutter of the heat shrink tube cutting mechanism 72. The heat shrink tube threading mechanism 73 includes a tube gripper 731. The tube gripper 731 of the heat shrink tube threading mechanism 73 clamps the heat shrink tube to be cut when the heat shrink tube extends a preset length, and then the heat shrink tube cutting mechanism 72 cuts the heat shrink tube to be cut. The cut heat shrink tube will not fall under the clamping action of the tube gripper 731, and the tube gripper 731 transports the cut heat shrink tube to the wire with the terminals crimped and threads it. The heat shrink tube loading mechanism 71 is, for example, a heat shrink tube loading tray.

[0062] In one embodiment, the heat shrinking mechanism 8 includes a hot air gun 81, and the hot air gun 81 is swingably fixed to the frame.

[0063] In the above technical solution, the gripper transfers the wire that has been threaded with the heat shrink tube from the heat shrink tube cutting and threading mechanism 7 to the heat shrinking mechanism 8, and places the wire at the air outlet of the hot air gun 81; the driving device fixed to the frame drives the hot air gun 81 to swing, preheating the entire heat shrink tube sleeved on the wire to complete the pre-heat shrinking process, and then aligning the air outlet of the hot air gun 81 with the heat shrink tubes at the joints of the first terminal and the second terminal with the wire respectively, and intensively heating the joints of the wire and the terminals, so as to complete the complete heat shrinking process. By sequentially performing the pre-heat shrinking process and the complete heat shrinking process, the heat shrink fixing effect at the joints of the two terminals and the wire is improved, and at the same time, the heat shrinking time of the intermediate wire section is reduced, thereby improving the processing efficiency.

[0064] In one embodiment, the finished product collecting mechanism includes a finished product handling mechanism 91 and a collecting box 92.

[0065] The working process of the present utility model is as follows: The wire pre-laying mechanism 1 feeds the wire into the wire laying and cutting mechanism 2. The wire feeding mechanism 21 of the wire laying and cutting mechanism 2 positions the wire and feeds the wire into the cutting mechanism 22 of the wire laying and cutting mechanism 2. The cutting mechanism 22 cuts the wire to the required length and strips the first end of the wire. Then, the wire with the first end stripped is transported to the first terminal feeding and crimping mechanism 3. The terminal clamping mechanism 32 of the first terminal feeding and crimping mechanism 3 clamps the terminal from the feeding mechanism 31 and places it on the first end of the wire that has been stripped. Then, the terminal crimping is completed through the terminal crimping device 33. Subsequently, the wire with the first end completed with terminal crimping is transported to the automatic stripping mechanism 5 through the wire transfer mechanism 4. The second end of the wire is stripped at the automatic stripping mechanism 5. Then, the wire with the second end stripped is transported to the second terminal feeding and crimping mechanism 6, and the terminal crimping of the second end of the wire is completed using the same crimping device. Then, the wire with the terminal crimping completed is transported to the heat shrinkable tube cutting and threading mechanism 7 through a transfer device such as a jaw. After the heat shrinkable tube cutting and threading mechanism 7 cuts the heat shrinkable tube according to the wire length, the heat shrinkable tube is accurately sleeved on the wire. Then, the heat shrinkable tube sleeved on the wire is heat-shrunk through the heat shrinking mechanism 8. Finally, the finished wire product after heat shrinking is transported by the finished product collecting mechanism 9 and collected in a material box.

[0066] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: The wire pre-laying mechanism 1 is used for automatically feeding the wire. By setting the pulley group force-saving mechanism 13 in the wire pre-laying mechanism 1, it is possible to avoid the situation where the force between the wire and the wire pre-laying mechanism 1 is too concentrated during the wire feeding process, resulting in damage to the wire pre-laying mechanism 1 or the wire; The wire laying and cutting mechanism 2 is used to receive the wire released by the wire pre-laying mechanism 1, cut the wire to the required length and automatically send it out, and strip the first end of the cut wire; The first terminal feeding and crimping mechanism 3 is used for terminal feeding, receives the wire after stripping, and crimps the terminal at the first end crimping position of the wire; The wire is transferred to the second end crimping position by the wire transfer mechanism 4 after the terminal is crimped at the first end; The automatic stripping mechanism 5 strips the second end of the wire at the second end crimping position; The second terminal feeding and crimping mechanism 6 is used for terminal feeding, receives the wire stripped by the automatic stripping mechanism 5, and crimps the terminal at the second end of the wire; The heat shrinkable tube cutting and threading mechanism 7 can cut the heat shrinkable tube and sleave the cut heat shrinkable tube on the wire after the terminal crimping is completed; The heat shrinkable tube is heat-shrunk by the heat shrinkable mechanism 8; The finished product collecting mechanism 9 is used for handling the wire after heat shrinkage; Through the cooperation of the wire pre-laying mechanism 1, the wire laying and cutting mechanism 2 and other mechanisms, the length of the ultra-short wire of the ultra-short wire processing equipment is accurately cut, and the rapid processing of both ends of the wire is realized. Compared with general manual processing, the processing accuracy and processing efficiency of both ends of the ultra-short wire are improved.
