Description

Technical Field

[0001] This utility model relates to the field of terminal crimping technology, specifically a crimping device for cold-pressed terminals. Background Technology

[0002] With the continuous improvement of automation in wire processing technology, crimping of terminals has gradually replaced the previous welding process. Crimping of terminals is an important step in the wire assembly process. It reliably connects the wire core to the terminal by applying external force. It is simple and easy to operate and has been widely used in electrical, electronic, automotive and other industries.

[0003] However, most current crimping devices for cold-pressed terminals require operators to place the cable very close to the crimping device, which is dangerous and prone to vibration, leading to unsuccessful crimping. Therefore, we propose a crimping device for cold-pressed terminals. Utility Model Content

[0004] The purpose of this utility model is to provide a crimping device for cold-pressed terminals, so as to solve the problems mentioned in the background art that most current cold-pressed terminal crimping devices require operators to place the cable very close to the crimping device and are prone to vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crimping device for cold-pressed terminals, comprising a base, a support frame fixedly connected above the base, and a cylinder inside the support frame; a sliding plate, located above the base and slidably connected to the base, with slide rails on both sides of the sliding plate and fixedly connected above the base; a clamping mechanism, comprising a platform, a push plate, and a fixing block, which can better fix the wire and facilitate subsequent processing; and a crimping mechanism, comprising a crimping head and a lower die, which can crimp the terminals.

[0006] The cylinder's drive end is fixedly connected to the pressure joint. The cylinder is used to drive the pressure joint to move vertically. The pressure joint includes a slider connected to the cylinder's drive end by bolts. A mounting groove is connected below the slider, and the upper mold is detachably connected below the mounting groove.

[0007] The upper part of the skateboard is fixedly connected to the platform, the side of the platform is fixedly connected to the push plate, the push plate is L-shaped, a small cylinder is fixedly connected to the outside of the push plate, and the upper part of the push plate is fixedly connected to the fixed block.

[0008] The push plate has a base on the side away from the platform. The base is fixedly connected to the top of the slide plate. The base is fixedly connected to the lower mold. An electric telescopic rod is fixedly connected to the side of the base away from the push plate. A servo motor is fixedly connected to the side of the electric telescopic rod away from the base.

[0009] Servo motor No. 2 is fixedly connected above servo motor No. 1, and electric telescopic rod No. 2 is connected to the valley bottom on one side of servo motor No. 2. Limit block is fixedly connected to the telescopic end of electric telescopic rod No. 2.

[0010] A controller is fixedly connected to one side of the support frame.

[0011] This utility model has at least the following beneficial effects: During operation, the wire to be crimped is first placed on the platform of the clamping mechanism. The L-shaped push plate is driven by a small cylinder on the outside of the push plate to cooperate with the fixing block to form an automatic clamp, effectively fixing the position of the wire and preventing it from shifting. After clamping, the slide plate moves along the base slide rail to send the wire to the crimping station. At this time, the lower die has pre-placed the terminal block, and the wire end is aligned with the terminal slot. The cylinder of the crimping mechanism then drives the crimping head to press down vertically. The entire process is coordinated by the controller. The clamping mechanism replaces the traditional manual crimping, which improves production efficiency and ensures the safety of the operator's hands. In addition, the limit block can also effectively limit the wire from exceeding the terminal block, which can improve the stability of the crimping quality and prevent the risk of short circuit caused by the exposed metal core after crimping due to the wire being too long, or the problem of insufficient contact area and reduced conductivity caused by the wire being too short.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a crimping device for cold-pressed terminals, including a base 1, a support frame 11 fixedly connected above the base 1, and a cylinder 12 inside the support frame 11; a slide plate 2, located above the base 1 and slidably connected to the base 1, with slide rails 21 on both sides of the slide plate 2, and the slide rails 21 fixedly connected above the base 1; a clamping mechanism 3, including a platform 31, a push plate 32, and a fixing block 33, which can better fix the wire and facilitate subsequent processing; and a crimping mechanism 4, including a crimping head 41 and a lower mold 42, which can crimp the terminals.

[0018] The driving end of the cylinder 12 is fixedly connected to the pressure connector 41. The cylinder 12 is used to drive the pressure connector 41 to move vertically. The pressure connector 41 includes a slider 411 connected to the driving end of the cylinder 12 by bolts. A mounting groove 412 is connected below the slider 411. The upper mold 413 is detachably connected below the mounting groove 412.

[0019] The upper part of the skateboard 2 is fixedly connected to the platform 31, and one side of the platform 31 is fixedly connected to the push plate 32. The push plate 32 is L-shaped, and a small cylinder 34 is fixedly connected to the outer side of the push plate 32. The upper part of the push plate 32 is fixedly connected to the fixing block 33.

[0020] A base 43 is provided on the side of the push plate 32 away from the platform 31. The base 43 is fixedly connected above the slide plate 2. The base 43 is fixedly connected to the lower mold 42. An electric telescopic rod 44 is fixedly connected on the side of the base 43 away from the push plate 32. A servo motor 45 is fixedly connected on the side of the electric telescopic rod 44 away from the base 43.

[0021] Servo motor 2 is fixedly connected above servo motor 1 45. Electric telescopic rod 2 47 is connected to the valley bottom on one side of servo motor 2 46. Limit block 48 is fixedly connected to the telescopic end of electric telescopic rod 2 47.

[0022] A controller 49 is fixedly connected to one side of the support frame 11.

[0023] Before operation, place the terminal block in the slot of the lower mold 42 on the base 43. The wire passes through the platform 31 of the clamping mechanism 3 and abuts against the inner side of the push plate 32. After starting the controller 49, the small cylinder 34 on the outside of the push plate 32 pushes the L-shaped push plate 32 to move horizontally towards the platform 31. The fixed block 33 clamps the wire to ensure its vertical positioning. After clamping, the slide plate 2 slides along the slide rails 21 on both sides of the base 1 to transport the wire to the crimping station. At this time, the electric telescopic rod 47 drives the limit block 48 to extend and adjust to the preset position according to the terminal specifications to block the end of the wire to prevent over-insertion.

[0024] Servo motor 45 on one side of base 43 finely adjusts the horizontal position of lower mold 42 via electric telescopic rod 44, while servo motor 46 adjusts the longitudinal position of limit block 48 to achieve multi-dimensional precise positioning. Cylinder 12 in support frame 11 drives crimping head 41 to press vertically downward. Slider 411 drives replaceable upper mold 413 in mounting slot 412 to close with lower mold 42, completing the plastic crimping of terminal and wire. After crimping, cylinder 12 resets, clamping mechanism 3 releases wire, slide plate 2 returns to initial position to remove finished product. Controller 49 synchronously coordinates the movement of slide plate 2, stroke of cylinder 12 and action of electric telescopic rod. Upper mold 413 can be quickly replaced with bolts to adapt to different terminal models. Throughout the process, the coordinated action of limit block 48 and clamping mechanism 3 ensures consistent wire insertion depth.
