Description

Technical Field

[0001] This utility model relates to the field of automated equipment design and manufacturing, and in particular to a breaking mechanism for breaking terminal strips. Background Technology

[0002] In terminal assembly processes, to achieve precise connections between terminal connectors and other components, it is typically necessary to break the terminal strip. Current technologies often employ cylinder-driven systems for strip breaking. While this system can perform the breaking operation, it has several drawbacks. First, the cylinder-driven mechanism is complex, usually requiring multiple cylinders and their control devices, resulting in a large overall system size, cumbersome installation, debugging, and maintenance, and high costs. Second, due to the limited response speed of cylinders, the breaking speed is relatively slow, making it difficult to meet the efficiency requirements of modern high-speed production lines. Furthermore, influenced by factors such as strip material, thickness, and environmental conditions, traditional cylinder-driven methods often exhibit unstable breaking results under certain special conditions, such as incomplete breaking or residual material, thus affecting product quality. Simultaneously, in some terminal assembly processes, limited production space makes it difficult to rationally arrange traditional breaking mechanisms within confined spaces, further reducing work efficiency and potentially leading to positioning errors. Utility Model Content

[0003] To address the problems of complex structure, low efficiency, and potential errors in traditional breaking machines, the present invention aims to provide a breaking mechanism for breaking terminal strips, comprising: a fixed base, a slider baffle, a slider, an eccentric cam, a material trough mechanism, a reducer, and a motor; wherein, the fixed base is provided with a vertically extending slide rail, the slider is movably connected to the eccentric cam, and the material trough mechanism is fixedly connected to the slider; the eccentric cam is connected to the reducer, and the motor drives the reducer to rotate the eccentric cam; the rotation of the eccentric cam drives the slider to slide up and down along the slide rail on the fixed base, thereby driving the material trough mechanism connected to the slider to reciprocate up and down; the material trough mechanism is provided with a slot for allowing residual edge material of the terminal strip to pass through, and at least one opening with a cutting function that allows residual edge material of the terminal strip to pass through the connection point with the terminal.

[0004] Furthermore, at least one side of the at least one opening with a cutting function provided on the material trough mechanism has a blade-shaped structure that gradually narrows in the vertical direction. The blade-shaped structure breaks off the connection between the residual edge material of the terminal strip and the terminal during the reciprocating motion of the material trough mechanism.

[0005] Furthermore, the material trough mechanism includes a first material trough mechanism and a second material trough mechanism, and a channel is provided between the first material trough mechanism and the second material trough mechanism, the channel being used to allow terminals connected to the terminal strip to pass through.

[0006] Furthermore, the first and second material trough mechanisms are fixedly connected by elongated holes, screw holes, and screws in an adjustable manner to accommodate products of different specifications.

[0007] Furthermore, the slider baffle is disposed on the fixed base and cooperates with the slide rail on the fixed base to limit the lateral displacement of the slider during the vertical sliding process, thereby ensuring that the slider performs precise up and down sliding motion along the predetermined slide rail.

[0008] Furthermore, the motor is a servo motor, which achieves high-frequency stable up-and-down sliding motion of the slider by precisely controlling its output speed.

[0009] 1. Improved breaking speed: By using a servo motor to drive the breaking mechanism of this invention, a higher sliding frequency can be achieved, significantly improving the breaking speed of the strip, thereby meeting the needs of high-efficiency production.

[0010] 2. Stable breaking effect: The eccentric cam design ensures stable movement of the slider, guaranteeing consistency and reliability in every break.

[0011] 3. Simple structure and low cost: This utility model is based on motor drive, has a simple structure, low manufacturing cost, and is easy to install and maintain.

[0012] 4. Suitable for confined spaces: Through its optimized mechanical structure, this invention can achieve efficient breaking within a small installation space, improving the adaptability and flexibility of the equipment. Attached Figure Description

[0018] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, this utility model is a breaking mechanism for terminal strip breaking, suitable for breaking strips during terminal assembly, which can improve breaking speed and stability, and reduce manufacturing costs. This embodiment solves the problems of breaking speed and stability in traditional cylinder-driven devices through the design of a servo motor and an eccentric cam.

[0020] like Figures 1 to 3 As shown, where Figure 3 for Figure 2 A cross-sectional view along section line AA shows that the breaking mechanism of this invention includes the following main components:

[0021] Fixed base 1: used to support the stable operation of the entire mechanism, the fixed base 1 is provided with a slide 15 extending in the vertical direction.

[0022] Slider baffle 2: It is set on the fixed base 1 to restrict the movement direction of slider 6 and ensure that slider 6 slides up and down in the mechanism.

[0023] Material trough mechanism: Includes a first material trough mechanism 3 and a second material trough mechanism 4 fixedly connected to the slider 6, used to break off residual edge material of the terminal strip. A channel 14 is provided between the first material trough mechanism 3 and the second material trough mechanism 4, the channel 14 allowing terminals connected to the residual edge material of the strip to pass through, and the first material trough mechanism 3 and the second material trough mechanism 4 are connected by an elongated hole 19, a screw hole 20, and a screw ( Figure 2(Not shown in the figure) The connection can be adjusted to accommodate terminal strips of different specifications. Simultaneously, the first material trough mechanism 3 is provided with a groove 12, and the second material trough mechanism 4 is provided with a groove 13. The groove 12 of the first material trough mechanism 3 and the groove 13 of the second material trough mechanism 4 are respectively used to allow residual edge material from the left and right sides of the terminal strip to pass through. The groove 12 of the first material trough mechanism 3 has an opening 10 with a cutting function near the channel 14, and the groove 13 of the second material trough mechanism 4 has an opening 11 with a cutting function near the channel 14. The openings allow residual edge material of the strip to pass through the connection point with the terminal, and one side of the opening has a gradually narrowing blade-shaped structure. This blade-shaped structure breaks the connection between the residual edge material of the terminal strip and the terminal during the reciprocating motion of the material trough mechanism. Furthermore, if the terminal strip adapted to the material trough mechanism only includes residual edge material on one side, the material trough mechanism of the breaking mechanism of this utility model can only include a single-sided material trough mechanism fixedly connected to the slider 6 (not shown in the figure).

[0024] Eccentric cam 5 and slider 6: The slider 6 is movably connected to the eccentric cam 5. The eccentric cam 5 is connected to the reducer 8 shaft through the flat key 7, which converts the rotational motion of the motor 9 into the up-and-down sliding motion of the slider 6, driving the material trough mechanism to slide in the up-and-down direction.

[0025] Key 7: Used to connect the shafts of the eccentric cam 5 and the reducer 8 to ensure the stability of the rotational transmission.

[0026] Reducer 8: Converts the high-speed rotation of motor 9 into a low-speed, high-torque output to drive the eccentric cam 5 to rotate.

[0027] Motor 9: Provides a power source to drive the eccentric cam 5 in the reducer 8 to rotate, thereby moving the slider 6.

[0028] During operation, motor 9 drives reducer 8, which in turn drives slider 6 to slide up and down via eccentric cam 5. The first material trough mechanism 3 and the second material trough mechanism 4, mounted on slider 6, reciprocate vertically by the up-and-down sliding motion of slider 6, bending and breaking the residual edge material of the terminal strip.

[0029] The asymmetrical design of the eccentric cam 5 and the slider baffle 2 installed on the outside of the slide rail 15 on the fixed base 1 optimize the movement trajectory of the slider 6, ensuring the stability of the up-and-down sliding and ensuring that the breaking effect is uniform each time. The up-and-down sliding speed of the slider 6 is precisely controlled by a servo motor, ensuring high speed and stability in the breaking process.

[0030] This utility model is applicable to terminal products, such as... Figure 4The diagram shows a terminal strip processed according to a preferred embodiment of the present invention, where multiple terminals 16 are connected to the residual edge material 17 of the strip via connecting portions 18. The operational effect of the preferred embodiment of the present invention is as follows: Figure 5 As shown, the breaking mechanism is installed in the terminal assembly equipment. During equipment operation, the terminal strip is conveyed to the breaking mechanism of this invention, which effectively separates multiple terminals 16 and the residual strip material 17 connected to both sides of them by breaking the connecting part 18.

[0031] Specifically, terminal 16 is fed into the breaking mechanism via a transmission mechanism (not shown) fixed to the mounting equipment. The residual material strips 17 on both sides of terminal 16 pass through the slots 12 of the first material trough mechanism 3 and the slots 13 of the second material trough mechanism 4, respectively. Terminal 16 passes through the channel 14 between the first material trough mechanism 3 and the second material trough mechanism 4. The connection portion 18 connecting terminal 16 and the residual material strips 17 on both sides passes through the openings 10 of the slot 12 of the first material trough mechanism 3 and the openings 11 of the slot 13 of the second material trough mechanism 4, respectively. During the operation of the breaking mechanism, the first material trough mechanism 3 and the second material trough mechanism 4 continuously generate vertical relative displacement with the terminal material strips fixed to the transmission mechanism through high-frequency vertical reciprocating motion. The blade-shaped structures of the openings 10 of the slot 12 of the first material trough mechanism 3 and the openings 11 of the slot 13 of the second material trough mechanism 4 continuously bend the connection portion 18 between terminal 16 and the residual material strips 17 passing through the two openings until breakage is completed, thereby effectively separating terminal 16 and the residual material strips 17 on both sides.
