Description

Technical fields:

[0001] This utility model relates to the field of wire processing technology, and specifically to a cold-pressing terminal 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 automated terminal processing equipment.

[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] This terminal crimping machine uses a conveyor, a feeding cylinder, a feeder, a feeder, and a storage bin to work together to store wires in the storage bin and automatically load and unload them. However, for some terminals (such as pre-insulated terminals and multi-core wire terminals), they need to undergo two vibration adjustments when being conveyed from the storage bin to ensure accurate crimping with the wire. Otherwise, the crimped wires are prone to quality defects, making this terminal crimping machine unsuitable. In addition, this terminal crimping machine does not have wire stripping and twisting devices, requiring manual wire stripping, resulting in low work efficiency.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 5The image shows a cold-pressing terminal crimping machine, comprising: 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 beside the wire twisting module 3 for feeding terminals; and a vibrating disc module 5 disposed above the wire twisting module 3 for feeding terminals to the terminal feeding module 4. The terminal feeding module 4 includes a support base 41 disposed on the base plate 1 and located beside the wire twisting module 3, and a first guide rail 42 horizontally mounted on the lower end of the support base 41. The structure includes a swinging structure 43 that is swingable and mounted on the support base 41; a linear vibration structure 44 that is fixed to the upper end of the support base 41 and used to transfer terminals to the swinging structure 43; a blocking drive motor 45 mounted on one side of the support base 41; a blocking arm 46 that is telescopically mounted on the output shaft of the blocking drive motor 45 and used to block terminals to control the transfer speed; a terminal delivery drive structure 47 mounted on the base plate 1 and used to drive the swinging structure 43 to swing downward; and a gripper structure 48 mounted on the other side of the support base 41 and used to clamp terminals and transfer them to the swinging structure 43.

[0026] In this invention, by adding a direct vibration structure 44 to the terminal feeding module 4, the direct vibration structure 44 can perform secondary vibration adjustment on the terminal after it is vibrated out of the vibrating material tray module 5, so that the terminal can swing in the correct posture to facilitate terminal crimping. This effectively improves the accuracy and efficiency of wire processing and can also be adapted to the crimping of various terminals, improving adaptability. Furthermore, the first adjusting cylinder 432 of the swing structure 43 can drive the support plate 433 to extend and retract, thereby adapting to crimping terminals of wires of different lengths, making the equipment more adaptable.

[0027] In this embodiment, the swing structure 43 and the terminal delivery drive structure 47 are driven by a half-gear-rack transmission to make the swing plate 44 swing 90°. Specifically, the swing structure 43 includes a semi-circular gear 431 rotatably mounted on the support base 41, a first adjusting cylinder 432 fixed on the semi-circular gear 431, a support plate 433 telescopically mounted on the first adjusting cylinder 432, a second cylinder group 434 mounted on the support plate 433, a second gripper 436 slidably mounted on the second cylinder group 434 for clamping the terminal, a third cylinder group 437 mounted on the support plate 433, and a third gripper 438 slidably mounted on the third cylinder group 437 for clamping the terminal. The support plate 433 is telescopically adjustable on the first adjusting cylinder 432 to adapt to pressing wires of different lengths.

When the first drive cylinder 471 pushes the cylinder head 472 to move, it drives the rack 473 to drive the semi-circular gear 431 to rotate, so that the swing structure 43 swings.

[0029] The linear vibration structure 44 includes a linear vibrator 441 mounted on a support base 41, a first linear vibration channel 442 mounted on the linear vibrator 441 for receiving terminals vibrated from the vibrating material tray module 5, and a proximity switch 443 mounted beside the first linear vibration channel 442 for detecting the terminal spacing. The first linear vibration channel 442 is inclined. Here, the first linear vibration channel 442 is connected to the terminal conveying channel 54 of the vibrating material tray module 5, and the first linear vibration channel 442 has a slope. The linear vibrator 441 vibrates to make the terminals flowing through the first linear vibration channel 442 have a lower center of gravity, so that the heavier metal parts face down and the parts that need to be pressed face up, to facilitate subsequent processing.

[0030] The gripper structure 48 includes a gripper support frame 481 mounted on a support base 41, a gripper telescopic motor 482 mounted on the gripper support frame 481, an L-shaped transmission plate 483 telescopically mounted on the output shaft of the gripper telescopic motor 482, a gripper drive motor 484 fixed on the L-shaped transmission plate 483, and a fifth clamping block 485 and a sixth clamping block 486 mounted at the lower end of the gripper drive motor 484 for gripping and transferring terminals.

[0031] The vibrating plate module 5 includes a vibrating plate support 51 mounted on the base plate 1, a vibrating plate 52 mounted on the vibrating plate support 51 for accommodating terminals, and a vibrating plate 53 mounted on the vibrating plate 52 for generating vibration. The vibrating plate 52 is provided with a terminal conveying channel 54 for conveying terminals outward.

[0032] The wire clamping module 2 includes a wire clamping motor 21 mounted on a base plate 1, a wire clamping bracket 28 mounted next to the wire clamping motor 21, a wire clamping seat 22 mounted on the wire clamping bracket 28, a transmission plate 27 connecting the wire clamping motor 21 and the wire clamping seat 22, a first clamping block 23 and a second clamping block 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 mounted on the inner sides of the first clamping block 23 and the second clamping block 24, respectively.

[0033] The twisting module 3 includes a first slide rail 38 mounted on the 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.

[0034] 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.

[0035] 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.

[0036] The method of using this utility model is as follows: When the equipment is running, the wire is first inserted into the wire inlet 82, and then the wire clamp 32 of the twisting module 3 clamps the wire and pulls it inward to a preset length. Then, 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 stripping material falls into the waste collection box 7. Simultaneously, the wire is twisted after stripping. Further, combined with... Figure 3 and Figure 4 As shown, the terminal feeding drive structure 47 can drive the swing structure 43 to swing 90°. Assuming the swing structure 43 first swings upward to the side of the linear vibrating structure 44, the clamping structure 48 transfers the terminal on the linear vibrating structure 44 to the swing structure 43. Further, the swing structure 43 swings between the wire clamping module 2 and the wire twisting module 3. At this time, the second clamping jaw 436 and the third clamping jaw 438 crimp the wire to form terminals. This invention achieves simultaneous stripping, twisting, and terminal crimping of the wire, with precise coordination between the modules, effectively improving wire processing efficiency.

[0037] In summary, by adding a direct vibration structure 44 to the terminal feeding module 4, the direct vibration structure 44 can perform secondary vibration adjustment on the terminal after it is vibrated out of the vibrating material tray module 5. This allows the terminal to swing in the correct posture for terminal crimping, effectively improving the accuracy and efficiency of wire processing. It also adapts to the crimping of various terminals, enhancing its adaptability. Furthermore, the first adjusting cylinder 432 of the swing structure 43 can drive the support plate 433 to extend and retract, thus adapting to crimping terminals with wires of different lengths, giving the equipment greater adaptability. In addition, compared with existing structures, this invention includes a twisting module 3 for stripping and twisting the wire, eliminating the need for manual stripping and improving the automation level of the equipment.

[0038] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
