DETAILED DESCRIPTION
[0024] The following is combined with Figures 1 to 7 The utility model is described in detail.
[0025] The utility model provides a steerable wire-paying device for a terminal crimping machine, comprising a fixed plate 1, a wire-paying mechanism 2 being arranged above the fixed plate 1, the wire-paying mechanism 2 being sequentially provided with a wire-passing device 21, a first slider 22, and a first slide rail 23 slidably connected to the first slider 22, a bracket assembly 11 being provided on one side of the fixed plate 1, a connecting rod 12 being fixedly connected to the bottom of the first slide rail 23 being provided on the bracket assembly 11, a first transmission wheel 121 being provided at one end of the connecting rod 12, a first motor 13 being provided on one side of the fixed plate 1 for driving the first transmission wheel 121 to rotate, the first slider 22 being provided with a rack 221, a gear 14 being provided on the bracket assembly 11 for meshing with the rack 221, one side of the gear 14 passing through the bracket assembly 11 and being provided with a second transmission wheel 141, and a second motor 15 being provided on one side of the fixed plate 1 for driving the second transmission wheel 141 to rotate. In the present invention, the wire feeding device 21 is used to secure and release the wire. The first motor 13 drives the first transmission wheel 121 to rotate, causing the wire feeding mechanism 2 to flip at an angle of less than or equal to 90°. This can be used to adjust the direction of wire feeding, facilitating the feeding of the wire into the terminal crimping device in different directions. The second motor 15 drives the gear 14 to rotate, causing the first slider 22 to move back and forth along the first slide rail 23. In this structure, the first slider 22 drives the wire feeding device 21 during its sliding motion. When the first motor 13 drives the wire feeding mechanism 2 to rotate to a certain angle, so that the wire feeding end of the wire feeding device 21 faces the stripping device of the terminal crimping machine, the second motor 15 drives the wire feeding device 21 forward to feed the wire into the stripping device. After the wire stripping is completed, the second motor 15 drives the wire feeding device 21 backward to extract the wire from the stripping device. Finally, the first motor 13 drives the wire feeding mechanism 2 to rotate, causing the wire end to move to the terminal crimping device of the terminal crimping machine for terminal crimping.
[0026] The pay-off mechanism 2 is provided with a swingable support plate 24, on which a curved plate 241 and a seesaw plate 242 are provided, and an elastic member a243 is provided between the seesaw plate 242 and the pay-off mechanism 2. The support plate 24 is provided at the rear end of the pay-off mechanism 2 to support the wire and prevent the wire from being caught by the connecting rod 12 or the gear 14. The support plate 24 can swing slightly within an angle range of less than or equal to 30 degrees. The wire passes through the curved plate 241 and then enters the wire-passing device 21. When the first motor 13 drives the pay-off mechanism 2 to flip, at a specific angle, the wire abuts the curved plate 241 and bends. At this time, the tension generated by the pay-off end of the wire and the wire-passing device 21 on the wire will cause the wire to be tightened. The wire exerts pressure on the curved plate 241, which drives the support plate 24 to swing slightly, thereby relieving the tension of the wire and preventing the wire from breaking. When the support plate 24 moves, it will drive the seesaw 242 to move, causing the elastic member a243 to stretch and accumulate elastic force. When the pay-off device starts to flip or the pay-off end of the wire pays off the wire again and the wire is no longer overly taut, the elastic member a243 drives the support plate 24 to reset.
[0027] A second slide rail 222 is disposed above the first slide block 22, and a second slide block 25 is disposed at the bottom of the wire-passing device 21, slidably connected to the second slide rail 222. A limit plate a251 is disposed at one end of the second slide rail 222, and a limit plate b252 is disposed at the other end of the second slide rail 222. In this embodiment, the wire-passing device 21 is movably connected to the first slide block 22, and the limit plates a251 and b252 are used to limit the range of motion of the second slide block 25, preventing it from falling off.
[0028] More specifically, the second slider 25 is provided with a positioning hole 253, which is provided with an elastic member b254. One end of the elastic member b254 abuts against the limit plate a251. The second slider 25 is fixedly connected to the wire-passing device 21. The elastic member b254 provides a certain buffering performance for the wire-passing device 21. When the front end of the wire-passing device 21 strikes other equipment or is struck by other objects, the wire-passing device 21 can move backward to mitigate the impact force, thus providing high safety performance.
[0029] The wire-passing device 21 is arranged in sequence on the wire-paying mechanism 2. Each wire-passing device 21 is provided with a first positioner 3 and a second positioner 4. The first positioner 3 is provided with a wire entry hole 31, and the second positioner 4 is provided with a wire exit hole 41. The wire entry hole 31 corresponds to the wire exit hole 41. The wire enters the first positioner 3 from the wire entry hole 31, passes through the second positioner 4, and then exits from the wire exit hole 41. The wire-passing device 21 is mainly used to fix the wire and adjust the wire-paying direction.
[0030] The first positioner 3 is provided with a plurality of linearly arranged wire wheels a32, each of which is provided with a wire groove 33 for positioning the wire. The wire wheels a32 are used to fix the wires and prevent the wires between the plurality of wire passing devices 21 from crossing or tying each other.
[0031] The first positioner 3 is provided with a lifting block 34, and a wire wheel b35 is provided on the lifting block 34. The first positioner 3 is also provided with an adjuster 36 that can adjust the position of the lifting block 34. The wire wheel b35 is set above the gap between the two adjacent wire wheels a32. The wire wheels b35 and a32 are internally provided with ratchet assemblies, so that the wire wheels b35 and a32 can only rotate in one direction. The wire wheel b35 is also provided with a wire groove 33. The staff can manually operate the adjuster 36 to lower the lifting block 34, and then let the wire wheel b35 and the wire wheel a32 cooperate to bite the wire material, so that the wire material can only move forward and cannot move backward, which can prevent the wire material from falling off and has high structural stability.
[0032] The second positioner 4 is provided with a wire hole 42 corresponding to the position of the wire inlet hole 31 and the wire outlet hole 41. The wire hole 42 is used to further position the wire. A wire presser 5 for fixing the wire is provided between the wire hole 42 and the wire outlet hole 41. The wire presser 5 can fix the wire so that the wire cannot move forward, making it easier to remove the wire end from the stripping device after stripping.
[0033] Specifically, the wire pressing device 5 is provided with a through-hole 51, and a limiting portion 52 is provided in the through-hole 51. The through-hole 51 is movably connected to the second positioner 4. The wire passes through the through-hole 42 and then enters the outlet hole 41. When the wire pressing device 5 is movable, the limiting portion 52 can cooperate with the inner wall of the second positioner 4 to clamp the wire.
[0034] More specifically, the top of the wire presser 5 passes through the second retainer 4 and is equipped with a curved arm 53. The bottom of the wire presser 5 passes through the second retainer 4 and is equipped with a locking block 54. An elastic member c55 is provided between the locking block 54 and the second retainer 4. Applying pressure to the curved arm 53 pries the wire presser 5 upward, causing the retainer 52 to press the wire against the top of the inner wall of the second retainer 4. The elastic member c55 can push the locking block 54 away, causing the wire presser 5 to return to its original position.
[0035] A smooth limiting plate c56 is provided at the end of the curved arm 53, and a limiting block 6 is provided above the second positioner 4 to limit the movable position of the limiting plate c56. When the wire presser 5 is in the reset state, the curved arm 53 and the limiting plate c56 extend obliquely upward and rearward. When the wire passing device 21 moves forward, the limiting plate c56 abuts the limiting block 6. As the wire passing device 21 moves, the limiting block 6 continuously applies pressure to the limiting plate c56, thereby causing the curved arm 53 to pry the wire presser 5. This structure is specifically manifested in that the first motor 13 drives the wire-releasing device to rotate so that the wire outlet hole 41 is aligned with the stripping device, and then the second motor 15 drives the wire-passing device 21 to move forward, and sends the end of the wire into the stripping device for stripping. During the movement of the wire-passing device 21, the limit plate c56 abuts against the limit block 6, so that the wire presser 5 rises and fixes the wire to prevent the stripping device from pulling the wire; after the wire stripping is completed, the wire-passing device 21 moves backward and resets, the limit plate c56 separates from the limit block 6, and the elastic member c55 drives the wire presser 5 to reset, thereby releasing the action of fixing the wire.
[0036] The elastic member a243, the elastic member b254 and the elastic member c55 described in the utility model are all reset springs.
[0037] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
