Description

Technical Field

[0001] This utility model relates to the field of terminal wire production technology, and in particular to a one-to-many terminal wire crimping machine. Background Technology

[0002] In the production of terminal wires, terminals need to be riveted onto the wire. Before riveting the terminals, the ends of the wire generally need to be stripped. In existing patents, the applicant filed a Chinese patent application on September 26, 2024, with application number 202422361897.2, disclosing a device for simultaneous double-end terminal crimping and inserting of wire harnesses. This device includes: a first terminal crimping station, a stripping and cutting mechanism, a stripping mechanism, a wire feeding mechanism, a wire pulling mechanism, a first wire feeding mechanism, and a second wire feeding mechanism. This device allows the stripping and cutting mechanisms to strip the wire harness at both ends, and then the first and second wire feeding mechanisms feed the wire harness to a first and second terminal crimping machine for terminal crimping. While this patent allows for the riveting of terminals to both ends of the wire to produce one-to-one terminal wires, in practical applications, some situations require one-to-many terminal wires, which this patent cannot meet. Therefore, the shortcomings are obvious, and a solution is urgently needed. Utility Model Content

[0014] The beneficial effects of this utility model are as follows: In practical application, the first wire feeding mechanism supplies wire to the wire feeding device, which corresponds to the first wire cutting and stripping device. The wire feeding device conveys the end of the wire to the first wire cutting and stripping device, which cuts and strips the wire end. Then, the first wire feeding drive mechanism drives the wire feeding device, along with the wire after cutting and stripping, to the first crimping terminal device. The first crimping terminal device crimps the cut and stripped end of the wire. Then, the first wire feeding drive mechanism drives the wire feeding device, along with the wire after crimping, to the first CCD detection mechanism. The first CCD detection mechanism performs quality inspection on the wire after crimping. Finally, the first wire feeding drive mechanism drives the wire feeding device, along with the quality inspection device, to the first CCD detection mechanism. After testing, the wire is moved to the first wire cutting and stripping device. Then, the first wire clamping and pulling device clamps the wire at the first wire cutting and stripping device and pulls the wire to the required length, allowing the wire to pass through the first wire cutting and stripping device. The wire pulled to a certain length is placed on the wire support table, which supports the wire. Next, the wire transfer mechanism moves between the first wire cutting and stripping device and the first wire clamping and pulling device and clamps the wire. Then, the first wire cutting and stripping device cuts and strips the wire, cutting and stripping the end of the wire on the wire feeding device. Then, the wire transfer mechanism moves the clamped wire (one end of which has a cut and the other end has a terminal crimped) along the wire support table to the first wire cutting and stripping mechanism, which then cuts and strips the cut end of the wire. The wires are cut and stripped. Then, a wire storage robot transfers the stripped wires along a wire support table to a storage device for storage. Once the required quantity of wires is stored in the storage device, a wire transport mechanism clamps the stored wires and transports them along the wire support table to a heat shrink tubing machine. The heat shrink tubing machine applies heat shrink tubing of a predetermined length to the required quantity of wires (wire groups). Next, the wire transport mechanism transports the wire groups with heat shrink tubing along the wire support table to the second crimping terminal device. Simultaneously, a second wire supply mechanism supplies wires to the wire feeding mechanism. At this point, the wire feeding mechanism corresponds to the second cutting and stripping device, which delivers the end of the wire to the second cutting and stripping device, where it cuts and strips the wire end. Next, the second wire feeding drive mechanism drives the wire feeding mechanism, along with the stripped wire, to the second crimping terminal device, where it mates with the end of the wire assembly. The second crimping terminal device then crimps the wire on the feeding mechanism to the mating portion of the wire assembly, crimping a single wire and the wire assembly together through a central terminal to form a pair of multiple wires. Then, with the coordinated operation of the second wire feeding drive mechanism and the wire transport mechanism, the pair of multiple wires is moved between the second CCD detection mechanism and the heat shrink tubing positioning adjustment mechanism. The second CCD detection mechanism first performs quality inspection and visual positioning on the crimped central terminal of the pair of multiple wires. The heat shrink tubing positioning adjustment mechanism then clamps the heat shrink tubing fitted outside the wire assembly and drives it to move to the position outside the central terminal.The heat shrink tubing wraps around the middle terminal of a pair of multiple wires. Then, a translational drive mechanism moves the second wire-clamping and pulling device to the heat shrink tubing positioning and adjusting mechanism, clamping the wire group. With the cooperation of the second wire feeding drive mechanism and the translational drive mechanism, the pair of multiple wires with the heat shrink tubing around the middle terminal are moved along the wire support table to the heat shrink tubing heat-shrink forming device. The heat shrink tubing heat-shrink forming device heats the heat shrink tubing to shrink it and securely wrap it around the middle terminal. Next, with the cooperation of the second wire feeding drive mechanism and the translational drive mechanism, the pair of multiple wires with the heat-shrink tubing is moved to the second wire-cutting and stripping device. During this process, the second wire-clamping and pulling device also pulls the wires on the wire feeding mechanism forward to the required length. Then, the second cutting... The wire stripping device cuts and strips the wires on the wire feeding mechanism. Then, a translational drive mechanism drives a second wire-clamping and pulling device, along with the cut wires, to the second wire-cutting and stripping mechanism. The second wire-cutting and stripping mechanism cuts and strips the wires at the cut points. A third CCD detection mechanism detects the quality of the wire cutting and stripping and visually locates the stripped positions. Then, the translational drive mechanism drives the second wire-clamping and pulling device, along with the stripped wires, to the third terminal-pressing device. The third terminal-pressing device presses terminals onto the stripped positions of the wires to produce a pair of terminal wires. Finally, a finished product output robot picks up the pair of terminal wires from the second wire-clamping and pulling device and outputs them to a designated location. This invention enables fully automated production of pair-of-terminal wires, with high production efficiency, good quality, and reduced labor intensity and costs. Attached Figure Description

The system includes: a wire handling mechanism 22, movable between the wire storage device 10, the heat shrink tubing machine 13, the second crimping terminal device 14, and the heat shrink tubing positioning adjustment mechanism 16; a third crimping terminal device 23 located to the left of the second wire cutting and stripping mechanism 18; a second wire clamping and pulling device 24 movably located in front of the second wire cutting and stripping device 17; a translation drive mechanism 25 for driving the second wire clamping and pulling device 24 between the second wire cutting and stripping device 17, the second wire cutting and stripping mechanism 18, and the third crimping terminal device 23; a wire support platform 26 mounted on the machine base 1 and capable of supporting wires 72 or wire groups 75; and a finished product output robot 27 located to the left of the third crimping terminal device 23. Specifically, a third CCD detection mechanism 77 is provided above the second wire cutting and stripping mechanism 18. Figure 10 As shown, specifically, a pair of multi-terminal wires consists of a terminal 71, a middle terminal 74, a heat shrink tubing 73, a wire 72, and a wire assembly 75.

[0027] In practical applications, the first wire feeding mechanism 8 supplies wire to the wire feeding device 6. At this time, the wire feeding device 6 corresponds to the first wire cutting and stripping device 2. The wire feeding device 6 conveys the end of the wire to the first wire cutting and stripping device 2, which cuts and strips the wire end. Then, the first wire feeding drive mechanism 7 drives the wire feeding device 6, along with the wire after cutting and stripping, to the first crimping terminal device 4. The first crimping terminal device 4 crimps the cut and stripped end of the wire. Then, the first wire feeding drive mechanism 7 drives the wire feeding device 6, along with the crimped wire, to the first CCD detection mechanism 5. The first CCD detection mechanism 5 performs quality inspection on the crimped wire. Then, the first wire feeding drive mechanism 7 drives the wire feeding device 6, along with the wire after crimping, to the first CCD detection mechanism 5. After quality inspection, the wire is moved to the first wire cutting and stripping device 2. Then, the first wire clamping and pulling device 3 clamps the wire at the first wire cutting and stripping device 2 and pulls the wire to the required length, so that the wire passes through the first wire cutting and stripping device 2. The wire pulled to a certain length is placed on the wire support table 26, which can support the wire. Then, the wire transfer mechanism 12 moves between the first wire cutting and stripping device 2 and the first wire clamping and pulling device 3 and clamps the wire. Then, the first wire cutting and stripping device 2 cuts and strips the wire, so that the end of the wire 72 on the wire feeding device 6 is cut and stripped. Then, the wire transfer mechanism 12 moves the clamped wire (one end of which has a cut and the other end has a terminal crimped) along the wire support table 26 to the first wire cutting and stripping device 2. At the first wire stripping mechanism 9, the wire stripping mechanism 9 cuts and strips the wire at the cut end. Then, the wire storage robot 11 transfers the stripped wire along the wire support table 26 to the wire storage device 10 for storage. Once the wire storage device 10 has stored the required number of wires, the wire transport mechanism 22 clamps the required number of wires stored in the wire storage device 10 and transports them along the wire support table 26 to the heat shrink tubing machine 13. The heat shrink tubing machine 13 applies a fixed length of heat shrink tubing to the required number of wires (wire group 75). Then, the wire transport mechanism 22 transports the wire group with the heat shrink tubing along the wire support table 26 to the second crimping terminal device 14. Simultaneously, the second wire supply mechanism 20 supplies wire to the wire feeding mechanism 19. At this time, the wire feeding mechanism 19 and the second crimping terminal device 14... Corresponding to the second wire stripping device 17, the wire feeding mechanism 19 conveys the end of the wire to the second wire stripping device 17, which strips the wire end. Then, the second wire feeding drive mechanism 21 drives the wire feeding mechanism 19, along with the stripped wire, to the second crimping terminal device 14, where it docks with the end of the wire group. The second crimping terminal device 14 then crimps the docking portion of the wire and the wire group on the wire feeding mechanism 19, so that a wire and a wire group are crimped together through the middle terminal to form a pair of multiple wires. Then, with the cooperation of the second wire feeding drive mechanism 21 and the wire transport mechanism 22, the pair of multiple wires is moved between the second CCD detection mechanism 15 and the heat shrink tubing positioning adjustment mechanism 16.The second CCD inspection mechanism 15 first performs quality inspection and visual positioning on the crimped middle terminal of the pair of multiple wires. Then, the heat shrink tubing positioning adjustment mechanism 16 clamps the heat shrink tubing sleeved outside the wire group and drives the heat shrink tubing to move outside the middle terminal, so that the heat shrink tubing wraps around the middle terminal of the pair of multiple wires. Then, the translation drive mechanism 25 drives the second wire clamping and pulling device 24 to move to the heat shrink tubing positioning adjustment mechanism 16 and clamps the wire group. Then, the second wire feeding drive mechanism 21... With the cooperation of the translation drive mechanism 25, a pair of multiple wires with heat shrink tubing sleeved outside the middle terminal are moved along the wire support table 26 to the heat shrink tubing heat shrink forming device 78. The heat shrink tubing heat shrink forming device 78 heats the heat shrink tubing to shrink it and firmly cover the middle terminal. Then, with the cooperation of the second wire feeding drive mechanism 21 and the translation drive mechanism 25, the pair of multiple wires with the heat shrink tubing after heat shrink forming are moved to the second wire cutting and stripping device 17. During the process, the second wire-clamping and pulling device 24 will also pull the wire on the wire feeding mechanism 19 forward to the required length. Then, the second wire-cutting and stripping device 17 will cut and strip the wire on the wire feeding mechanism 19. Next, the translation drive mechanism 25 will drive the second wire-clamping and pulling device 24, along with the pair of wires with cuts, to move along the wire support table 26 to the second wire-cutting and stripping mechanism 18. The second wire-cutting and stripping mechanism 18 will cut and strip the cuts of the pair of wires, and the third CCD detection mechanism 77 will detect the wires. The quality of the wire stripping is inspected, and the stripped areas are visually located. Then, the translation drive mechanism 25 drives the second wire clamping and pulling device 24, along with the stripped pair of wires, to move along the wire support table 26 to the third riveting terminal device 23. The third riveting terminal device 23 rivets the terminals onto the stripped areas of the pair of wires to produce a pair of terminal wires. Finally, the finished product output robot 27 picks up the pair of terminal wires from the second wire clamping and pulling device 24 and outputs them to a designated location. This invention enables fully automated production of pair of terminal wires, with high production efficiency, good quality, and reduced labor intensity and costs. For example, this invention can produce a pair of four-terminal wires or a pair of three-terminal wires.

[0028] Specifically, the heat shrink tubing heat shrink forming device 78 can be a heat blowing device; in practical applications, the heat blowing device blows hot air onto the heat shrink tubing so that the heat shrink tubing is heated and shrinks and wraps around the middle terminal.

[0029] In this embodiment, the heat shrink tubing threading machine 13 includes a heat shrink tubing rack 28 mounted on the machine base 1, a threading platform 29 mounted on the machine base 1 and located in front of the heat shrink tubing rack 28, a threading drive mechanism 30 mounted on the machine base 1 or the threading platform 29, a movable seat 31 connected to the drive end of the threading drive mechanism 30, a tubing clamping mechanism 32 mounted on the movable seat 31 and located on the front end face of the threading platform 29, a drive roller 33 rotatably connected to the top surface of the threading platform 29, a swing arm 34 rotatably connected to the threading platform 29, a driven roller 35 rotatably connected to the swing arm 34 and disposed opposite to the drive roller 33, an elastic member 36 elastically connected between the threading platform 29 and the swing arm 34, a rotation driver 37 mounted on the threading platform 29 and used to drive the drive roller 33 to rotate, a bracket 38 mounted on the front side of the threading platform 29, and a bracket mounted on the support. The support 38 includes a cutting mechanism 39 and multiple wire clamping mechanisms 40 arranged in a straight line on the support 38 and located in front of the clamping mechanism 32. A tube-passing gap 41 exists between the clamping ends of two adjacent wire clamping mechanisms 40. An elastic element 36 applies a force towards the driving roller 33 to the driven roller 35 via a swing arm 34. A tube-passing gap 44 is provided between the driving roller 33 and the driven roller 35. A first guide sleeve 42 and a second guide sleeve 43 are mounted on the top surface of the tube-passing platform 29. The first guide sleeve 42 and the second guide sleeve 43 are coaxially arranged and located at the feed end and discharge end of the tube-passing gap 44, respectively. The cutting end of the cutting mechanism 39 is located between the discharge end of the second guide sleeve 43 and the clamping end of the clamping mechanism 32. The tube-passing drive mechanism 30 can drive the moving seat 31 and the clamping mechanism 32 to move intermittently. Specifically, the rotary drive 37 can be a motor, and the elastic element 36 can be a torsion spring or a tension spring.

[0030] In practical applications, multiple clamping mechanisms 40 clamp the wire assembly, aligning it with the clamping end of the tube clamping mechanism 32. The heat shrink tubing roll is mounted on the heat shrink tubing rack 28. The heat shrink tubing of the roll passes sequentially through the first guide sleeve 42, the tube gap 44, and the second guide sleeve 43. The first and second guide sleeves 42 and 43 guide the movement of the heat shrink tubing. The rotary driver 37 drives the active roller 33 to rotate. The elastic element 36 applies a force towards the active roller 33 to the driven roller 35 via the swing arm 34. The active roller 33 and the driven roller 35 respectively abut against both sides of the heat shrink tubing. The rotating active roller 33 and the driven roller 35 cooperate to drive the heat shrink tubing forward, moving it to the required length to the clamping end of the tube clamping mechanism 32. After the clamping end of the tube clamping mechanism 32 holds the heat shrink tubing, it is then cut. Mechanism 39 cuts the heat shrink tubing, allowing the clamping end of the tubing clamping mechanism 32 to hold a fixed length of heat shrink tubing. Then, the tubing insertion drive mechanism 30 drives the moving seat 31, along with the clamping mechanism 32 and the fixed-length heat shrink tubing, to move closer to the wire assembly. The clamping mechanism 32 first places the fixed-length heat shrink tubing onto the end of the wire assembly. After the first clamping mechanism 40 releases the wire assembly, the clamping mechanism 32 moves the fixed-length heat shrink tubing into the first insertion gap 41, where it re-clamps the wire assembly. After the second clamping mechanism 40 releases the wire assembly, the clamping mechanism 32 moves the fixed-length heat shrink tubing into the second insertion gap 41, where it re-clamps the wire assembly. This segmented approach to fitting the heat shrink tubing onto the wire assembly facilitates smooth and efficient fitting. This structural design automatically fits the heat shrink tubing onto the wire assembly.

[0031] In this embodiment, the heat shrink tubing threading machine 13 further includes a guide seat 45 mounted on the top surface of the threading platform 29 and located behind the first guide sleeve 42. The guide seat 45 has a guide hole 46 coaxially arranged with the first guide sleeve 42. The guide seat 45 is equipped with a sensor 47, which is used to detect whether there is heat shrink tubing in the guide hole 46. The sensor 47 is electrically connected to the control system of the machine. In practical applications, the heat shrink tubing of the heat shrink tubing roll passes through the guide hole 46 of the guide seat 45. The guide hole 46 guides the heat shrink tubing. The sensor 47 detects the heat shrink tubing in the guide hole 46. When the sensor 47 detects that there is no heat shrink tubing in the guide hole 46, the sensor 47 sends a signal to the control system of the machine, causing the control system to issue an alarm to remind the operator to maintain or replace the heat shrink tubing roll on the heat shrink tubing rack 28.

[0032] In this embodiment, the wire storage device 10 includes a base 48 mounted on the machine base 1, a lifting drive mechanism 49 mounted on the base 48, a lifting seat 50 mounted on the lifting end of the lifting drive mechanism 49, a wire fixing plate 51 mounted on the lifting seat 50, a plurality of upper wire pressing blocks 52 that are lifted and lowered above the wire fixing plate 51, a plurality of upper wire pressing drivers 53 mounted on the lifting seat 50 and drivenly connected to the plurality of upper wire pressing blocks 52, a plurality of lower wire pressing blocks 54 that are lifted and lowered below the wire fixing plate 51, and a plurality of lower wire pressing drivers 55 mounted on the lifting seat 50 and drivenly connected to the plurality of lower wire pressing blocks 54. The upper wire pressing drivers 53 are used to drive the upper wire pressing blocks 52 to move closer to or away from the wire fixing plate 51, and the lower wire pressing drivers 55 are used to drive the lower wire pressing blocks 54 to move closer to or away from the wire fixing plate 51. Specifically, both the upper wire pressing drivers 53 and the lower wire pressing drivers 55 can be cylinders.

[0033] In practical applications, initially, the upper pressing block 52 and the fixing plate 51 are both open, as are the lower pressing block 54 and the fixing plate 51. The wire storage robot 11 delivers the required number of wires one by one between the corresponding upper pressing block 52 or lower pressing block 54 and the fixing plate 51. When the wire is between the upper pressing block 52 and the fixing plate 51, the upper pressing driver 53 drives the upper pressing block 52 to move closer to the fixing plate 51 until the upper pressing block 52 presses the wire onto the fixing plate 51. Similarly, the lower pressing block 54 presses the wire onto the fixing plate 51 until the wire storage device 10 stores the required number of wires. The lifting drive mechanism 49 drives the lifting seat 50 to rise and fall, adjusting the height of the fixing plate 51, thereby clamping the wires between the upper pressing block 52 and the fixing plate 51, and between the lower pressing block 54 and the fixing plate 51.

[0034] In this embodiment, both the upper pressure block 52 and the lower pressure block 54 are provided with V-shaped pressure grooves 56. When the upper pressure block 52 or the lower pressure block 54 clamps the wire onto the wire fixing plate 51, the wire is located within the V-shaped pressure groove 56. The inclined surface of the V-shaped pressure groove 56 can correct the wire's deviation, thereby improving the wire's positional accuracy and stability.

[0035] In this embodiment, there are multiple wire feeding devices 6, which are arranged side-by-side at the drive end of the first wire feeding drive mechanism 7. In practical applications, the first wire cutting and stripping device 2 can systematically cut and strip the wires on the multiple wire feeding devices 6, and the first crimping terminal device 4 can crimp terminals onto the wires on the multiple wire feeding devices 6 according to a program. This structural design improves production efficiency.

[0036] In this embodiment, multiple wire feeding devices 6 are mounted on the drive end of the first wire feeding drive mechanism 7 via a pitch angle adjustment mechanism 57. The pitch angle adjustment mechanism 57 is used to drive the pitch tilt angle of the multiple wire feeding devices 6. When the wires are of different diameters or the ends of the wires need to be placed on the first wire cutting and stripping device 2 and the first crimping terminal device 4 at different heights, the pitch angle adjustment mechanism 57 can drive the multiple wire feeding devices 6 to adjust their pitch angles in the vertical direction simultaneously, thereby adjusting the pitch tilt angle of the multiple wire feeding devices 6 and adjusting the height of the ends of the wires on the wire feeding devices 6, preventing the ends of the wires from drooping and being unable to be placed in the accurate position.

[0037] In this embodiment, there are multiple first crimping terminal devices 4. Multiple first crimping terminal devices 4 can crimp different terminals onto the wires on multiple wire feeding devices 6.

[0038] In this embodiment, the first wire clamping and pulling device 3, the second wire clamping and pulling device 24, the wire transfer mechanism 12, and the wire handling mechanism 22 all include a left and right linear drive module 58 mounted on the machine base 1, a front and rear linear drive module 59 mounted on the drive end of the left and right linear drive module 58, a mounting base 60 mounted on the drive end of the front and rear linear drive module 59, a guide rod 61 disposed on the mounting base 60, a slide block 62 slidably sleeved on the guide rod 61, a spring 63 sleeved outside the guide rod 61, a wire clamping assembly 64 movably disposed on the slide block 62, and an opening and closing clamping driver 65 mounted on the mounting base 60 and used to drive the wire clamping assembly 64 to open or close. The two ends of the spring 63 elastically abut against the bottom surface of the slide block 62 and the bottom of the mounting base 60, respectively.

[0039] In practical applications, the opening and closing clamp driver 65 drives the wire clamping assembly 64 to open (open the clamp). After the wire is positioned between the open wire clamping assemblies 64, the opening and closing clamp driver 65 drives the wire clamping assembly 64 to close, thus clamping the wire. The left and right linear drive module 58 is used to drive the wire clamping assembly 64 to move left and right, and the front and rear linear drive module 59 is used to drive the wire clamping assembly 64 to move back and forth. With the coordinated operation of the left and right linear drive module 58 and the front and rear linear drive module 59, the position of the wire clamping assembly 64 is adjusted. Among them, the spring 63 plays a buffering role against the slide 62.

[0040] In this embodiment, the wire clamping assembly 64 includes a lifting slider 66, two clamping claws 67, and two connecting rods 68. The opening and closing clamping actuator 65 is a cylinder. The lifting slider 66 is slidably connected to the slide base 62. The bottom of the lifting slider 66 is connected to the piston rod of the cylinder. The bottom ends of the two connecting rods 68 are coaxially hinged to the top of the lifting slider 66. The middle parts of the two connecting rods 68 are respectively hinged to the slide base 62. The top ends of the two connecting rods 68 are respectively hinged to the bottom ends of the two clamping claws 67. The middle parts of the two clamping claws 67 are respectively hinged to the slide base 62. The top ends of the two clamping claws 67 are each provided with a clamping groove 69 that cooperates with each other. Specifically, the slide base 62 has a Y-shaped groove 70. The two connecting rods 68 and the lifting slider 66 are roughly Y-shaped, and the two connecting rods 68 and the lifting slider 66 are located in the Y-shaped groove 70.

[0041] In practical applications, the piston rod of the cylinder extends and retracts to drive the lifting slider 66 to rise and fall. The rising and falling slider 66 drives two connecting rods 68 to swing back and forth. The two swinging connecting rods 68 drive the two wire clamping claws 67 to open or close. When the two wire clamping claws 67 clamp the wire, if the piston rod of the cylinder also pulls the lifting slider 66 to move downward, the downward force will act on the slide block 62 through the wire clamping assembly 64, causing the slide block 62 to move downward and compress the spring 63. This not only buffers the slide block 62, but also prevents the clamping force of the wire clamping assembly 64 from being too large.

[0042] Specifically, an air blowing hole 76 is provided at the middle of the two clamping claws 67 at an upward angle. When the two clamping claws 67 are clamping the wire, the air blowing hole 76 blows positive pressure gas outward at an angle. This positive pressure gas blows air into the wire to prevent the wire from sagging and causing the two clamping claws 67 to be unable to clamp the wire stably and accurately.

[0043] All technical features in this embodiment can be freely combined according to actual needs. Specifically, mechanisms and / or devices not described in detail in this embodiment can be corresponding mechanisms and / or devices in the prior art.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
