Description

Technical fields:

[0001] This utility model relates to the field of wire processing technology, and specifically to an improved automatic terminal crimping machine. Background technology:

[0002] Currently, the use of wires is increasing, and the variety of types is also growing. As the lifespan of electrical equipment increases, the requirements for wire quality are also rising, leading to a surge in demand. In the production process, it is often necessary to combine wires of different thicknesses and then crimp them together with terminals to meet specific applications. Such combined wires are convenient to use and have a long service life. Initially, the production of these combined wires was done manually, using terminal pliers to rivet terminals to the same end of two different wires. However, this method was inefficient, labor-intensive, and produced unsatisfactory quality, gradually failing to meet the demands of mass production. It was eventually replaced by automatic terminal crimping machines.

[0003] Currently, some terminal crimping machines on the market can achieve automatic loading and unloading. For example, Chinese utility model patent application CN218555427U discloses a semi-automatic terminal crimping machine with loading and unloading capabilities. It includes: a machine base, a terminal crimper, a conveyor, a discharge cylinder, a feeding cylinder, a feeder, a feeding cylinder, and a storage bin. The terminal crimper is installed on the top surface of the machine base, and the conveyor is installed on the top surface of the machine base at the processing port of the terminal crimper. The discharge cylinder is located adjacent to the conveyor. The top surface of the machine base is provided with a feeding trough adjacent to the conveyor, and a gap is left between the feeding trough and the feeding cylinder for wire to pass through. This semi-automatic terminal crimping machine can feed the wire in the storage box to the feeder through the feeding cylinder, and feed the wire to the terminal crimper for processing through the feeding cylinder. The conveyor and the feeding cylinder cooperate to feed the processed wire to the feeding trough, thereby automatically completing the wire feeding and unloading work, reducing the workload of the workers and improving work efficiency.

[0004] However, this existing terminal crimping machine still has the following shortcomings:

[0005] In this terminal crimping machine, the wires are stored in the storage box through the cooperation of the conveyor, feeding cylinder, feeder, feeder cylinder and storage box, and the wires can be automatically loaded and unloaded. However, this terminal crimping machine does not have a wire stripping and twisting device, so wire stripping is required by manual labor, which results in low work efficiency. In addition, its terminal crimper cannot be extended or adjusted, and it cannot be adapted to crimp terminals of wires of different lengths, resulting in poor adaptability.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figures 1 to 7 As shown, an improved automatic terminal crimping machine includes: a base plate 1; a wire clamping module 2 disposed on the base plate 1 for inserting wires; a wire twisting module 3 disposed beside the wire clamping module 2 for stripping and twisting the wires; a terminal feeding module 4 disposed between the wire clamping module 2 and the wire twisting module 3 in a swingable manner for crimping terminals; and a vibrating plate module 5 disposed above the wire twisting module 3 for feeding terminals to the terminal feeding module 4.

[0028] The terminal feeding module 4 includes a support base 42 mounted on the base plate 1 and located next to the twisting module 3; a support frame 43 horizontally mounted on the support base 42; a first slider rail A oscillatingly mounted on the upper end of the support base 42; a swing plate 44 fixed to the first slider rail A; an adjustment drive module 45 fixed to the first slider rail A and used to adjust the position of the swing plate 44 to adapt to crimping wires of different lengths; a terminal crimping module 41 fixed to the upper end of the swing plate 44; and a swing cylinder module 46 mounted on the support frame 43 and used to drive the terminal crimping module 41 to swing. The output shaft of the adjustment drive module 45 is connected to the swing plate 44, allowing the swing plate 44 to extend and retract along the first slider rail A to adjust the distance between the terminal crimping module 41 and the twisting module 3 after swinging down. This enables the crimping of terminals onto wires of different lengths, giving the equipment greater adaptability.

[0029] In this invention, by placing the terminal crimping module 41 on a swingable swing plate 44, the terminal crimping module 41 can quickly receive the terminal from the vibrating plate module 5 and swing between the twisting module 3 and the clamping module 2. This achieves simultaneous terminal crimping and wire stripping / twisting within a limited space, significantly improving wire processing efficiency. Furthermore, the swing plate 44 can extend and retract along the first slider rail A, adapting to crimp terminals onto wires of different lengths, thus enhancing the equipment's adaptability. In addition, compared to existing structures, this invention includes a twisting module 3 for stripping and twisting the wire, eliminating the need for manual stripping and resulting in a higher degree of automation.

[0030] The swing cylinder module 46 can drive the terminal crimping module 41 to swing 90°. During operation, the terminal crimping module 41 first swings upward to below the terminal conveying channel 54 of the vibrating plate module 5 and receives the terminal conveyed by the terminal conveying channel 54. Further, it swings between the wire clamping module 2 and the wire twisting module 3, through which the wire passes and the terminal is crimped. Specifically, the terminal crimping module 41 includes a lower mold 411, an eccentric plate 412 installed in the lower mold 411, several crimping blocks 413 distributed in the eccentric plate 412 for crimping the terminal onto the wire, a crimping cylinder 414 disposed in the lower mold 411 for driving the movement of the eccentric plate 412, a first transmission member 416 disposed between the crimping cylinder 414 and the eccentric plate 412 in a transmissive manner, and a cover plate 415 covering the lower mold 411. The cover plate 415 has a first through hole 401 for the wire to pass through, and the lower mold 411 has a second through hole 402 for the wire to pass through. The first through hole 401 also contains a mold core 403 adapted to the wire. The mold core 403 is made of flexible plastic to avoid damaging the wire.

[0031] In this embodiment, the swing cylinder module 46 drives the swing plate 44 to swing 90° via a half-gear-rack transmission method. Specifically, the swing cylinder module 46 includes a first drive cylinder 461 mounted on one end of the support frame 43, a transmission link 462 connected to the output end of the first drive cylinder 461, a first rack 463 connected to the transmission link 462 and driven by the first drive cylinder 461, and a half-gear 464 fixed to the upper end of the support base 42. The first slider rail A is fixed on the half-gear 464 and can swing accordingly.

[0032] In this embodiment, the loading and unloading of terminals is automatically completed through the vibrating disc module 5 and the guide module 6. Specifically, the vibrating disc module 5 includes a vibrating disc support 51 mounted on the base plate 1, a vibrating disc 52 mounted on the vibrating disc support 51 for accommodating terminals, and a vibrating disc 53 mounted on the vibrating disc 52 for generating vibration. The vibrating disc 52 is provided with a terminal conveying channel 54 for conveying terminals outward. The vibrating disc 52 is cylindrical, and the terminal conveying channel 54 is straight and tangent to the vibrating disc 52. A guide module 6 for guiding the terminals is also provided between the vibrating material tray module 5 and the terminal feeding module 4. The guide module 6 includes a guide tube 61 connected between the terminal feeding channel 54 and the terminal feeding module 4, a push cylinder 62 disposed on the side of the vibrating material tray module 5, a second transmission component 63 connected to the output end of the push cylinder 62, and a blocking piece 64 connected to the second transmission component 63 and extending into the terminal feeding channel 54 to block the terminals.

[0033] The wire clamping module 2 includes a wire clamping motor 21 mounted on a base plate 1, a wire clamping seat 22 mounted beside the wire clamping motor 21, a first clamping arm 23 and a second clamping arm 24 mounted inside the wire clamping seat 22 and clamped by the wire clamping motor 21, and a first clamping plate 25 and a second clamping plate 26 respectively mounted on the inner sides of the first clamping arm 23 and the second clamping arm 24. Here, the side of the first clamping plate 25 and the second clamping plate 26 that contacts the wire has a V-shaped opening to facilitate clamping the wire.

[0034] The twisting module 3 includes a first slide rail 38 mounted on a base plate 1, a first sliding seat 31 slidably mounted on the first slide rail 38, a wire clamp 32 mounted on the first sliding seat 31 for clamping the wire, a stripping knife 33 mounted on the wire clamp 32 for stripping the wire, a torsion drive motor 34 mounted on the first sliding seat 31 for driving the wire clamp 32 to rotate, a wire clamp drive motor 35 mounted on the first sliding seat 31 for driving the wire clamp 32 to clamp the wire, a push rod trigger switch 36 mounted at the front end of the wire clamp 32 for detecting whether the wire is in position, and a positioning sleeve 37 mounted at the front end of the push rod trigger switch 36 for positioning the wire. Here, a second drive motor 9 is provided on the base plate 1 for driving the first sliding seat 31 to slide back and forth along the first slide rail 38. When the wire extends into and touches the top rod trigger switch 36, the wire clamp 32 will be driven by the wire clamp drive motor 35 to clamp the wire. Further, the first sliding seat 31 slides backward along the first slide rail 38 to drag the wire to a preset length. Further, the stripping knife 33 strips the wire, and at the same time, the twist drive motor 34 drives the wire clamp 32 to twist the wire.

[0035] The base plate 1 is also provided with a waste collection box 7 for collecting wire sheaths, and the waste collection box 7 is located between the wire clamping module 2 and the wire twisting module 3. Here, the waste generated by the twisting module 3 during the wire processing will fall into the waste collection box 7.

[0036] The base plate 1 is also covered with a protective cover module 8 to prevent foreign objects from falling into the interior. The protective cover module 8 is equipped with a control panel 81 for displaying the working status of the device. The lower end of the protective cover module 8 is also equipped with a cable inlet 82 for inserting cables. At least two control buttons 83 for controlling the device are provided on the side of the control panel 81. An emergency stop button 84 for stopping the operation of the device is also provided on the side of the control panel 81.

[0037] When the equipment is running, the wire is first manually inserted into the inlet 82 and passed through the terminal crimping module 41. Then, the wire clamp 32 of the twisting module 3 clamps the wire and pulls it inward to a preset length. Next, the twisting drive motor 34 drives the wire clamp 32 to rotate the wire. At this time, the stripping blade 33 of the twisting module 3 strips the wire, and the wire insulation falls into the waste collection box 7. Simultaneously, the wire is twisted after stripping. Finally, the terminal crimping module 41 completes the terminal crimping, thus completing the processing. This invention achieves simultaneous stripping, twisting, and terminal crimping of the wire, with precise coordination between the modules, effectively improving wire processing efficiency.

[0038] In summary, by placing the terminal crimping module 41 on the swingable swing plate 44, the terminal crimping module 41 can quickly receive the terminal from the vibrating plate module 5 and swing between the twisting module 3 and the clamping module 2. This achieves simultaneous terminal crimping and wire stripping / twisting within a limited space, significantly improving wire processing efficiency. Furthermore, the swing plate 44 can extend and retract along the first slider rail A, adapting to crimp terminals onto wires of different lengths, thus enhancing the equipment's adaptability. In addition, compared to existing structures, the present invention includes a twisting module 3 for stripping and twisting the wire, eliminating the need for manual stripping and resulting in a higher degree of automation.
